For shareholders of
Janus Global Research Fund

December 19, 2012

Dear Shareholder:

We wanted to inform you, as a shareholder of Janus Global Research Fund, that the Trustees of your Fund have approved Janus’ proposal to merge the Fund into Janus Worldwide Fund, effective on or about March 15, 2013. Janus’ proposal to merge the two funds was based largely on similarities of the funds’ investment objectives, strategies and policies, as well as the anticipated expense efficiencies due to the larger asset base of the combined Fund after the merger. This merger is subject to approval by the shareholders of Janus Global Research Fund. If the merger is approved, you will receive the same class of shares of the combined Fund that you hold in Janus Global Research Fund as of the merger date.

Although your Fund is merging into Janus Worldwide Fund, after the merger, the combined Fund will continue to have the same investment objective, strategies, policies and portfolio management team that manages your Fund today. The combined Fund will be renamed Janus Global Research Fund, but will have the expense structure of Janus Worldwide Fund. That expense structure is very similar to your Fund’s existing expense structure, in that both Funds have a performance-based management fee, so your total expense ratio over time will fluctuate just as it does today. However, as explained in greater detail in the attached Q&A and Proxy Statement/Prospectus, there are certain differences between the Funds’ fee structures. The impact of these differences on future fees you might pay will depend on the future performance of the combined Fund.

The proposed merger offers a number of benefits to Janus Global Research Fund shareholders, including a lower base management fee rate, fee waivers that likely will result in a lower overall performance fee for three years after the merger, and for most Fund shareholders, lower total expenses than you currently pay. Also, the long-term performance track record of your Fund will remain in place. Finally, the merger is designed to qualify as a tax-free merger, so you should not realize a tax gain or loss as a direct result of the merger. Additional details about the proposed merger are described in the enclosed Q&A and Proxy Statement/Prospectus.

Your Fund’s Board of Trustees believes the proposed merger is in the best interest of shareholders and has recommended that shareholders vote “FOR” the merger.

You can vote in one of four ways:

•  By mail with the enclosed proxy card;

•  By internet through the website listed in the proxy voting instructions;

•  By telephone using the toll-free number listed in the proxy voting instructions; or

•  In person at the special shareholder meeting on March 8, 2013.

Your vote is extremely important, so please read the enclosed Proxy Statement/Prospectus carefully and submit your vote. If you have any questions about the proposal, please call our proxy solicitor, Computershare at 1-866-492-0863.

Thank you for your consideration of this important proposal. We value the trust and confidence you have placed with us and look forward to continuing our relationship with you.

Sincerely,

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

Notice is hereby given that the Board of Trustees of Janus Investment Fund (the “Trust”) has called a Special Meeting of Shareholders of Janus Global Research Fund (“Global Research Fund”), a series of the Trust, to be held at the JW Marriott Hotel, 150 Clayton Lane, Denver, Colorado 80206, on March 8, 2013, at 10:00 a.m. Mountain Time (together with any adjournments or postponements thereof, the “Meeting”). At the Meeting, shareholders will be asked to vote to approve an Agreement and Plan of Reorganization (the “Plan”), which provides for the merger of Global Research Fund into Janus Worldwide Fund (“Worldwide Fund”) (the “Merger”) and to transact such other business, if any, as may properly come before the Meeting.

The persons named as proxies will vote in their discretion on any other business that may properly come before the Meeting.

In the event that the necessary quorum to transact business or the vote required to approve the Plan is not obtained at the Meeting, the persons named as proxies may propose one or more adjournments to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of the holders of a majority of shares of Global Research Fund entitled to vote that are present in person or by proxy at the Meeting. If a quorum is not present, the persons named as proxies will vote the proxies, in accordance with applicable law, in favor of adjournment if they determine additional solicitation is warranted and in the interests of Global Research Fund’s shareholders.

Shareholders who do not expect to attend the Meeting are urged to complete, sign and date the enclosed proxy card(s) and return it in the enclosed addressed envelope, which needs no postage if mailed in the United States, or to take advantage of the Internet or telephonic voting procedures described on the enclosed proxy card(s).

INTRODUCTION

This Proxy Statement/Prospectus is being furnished to shareholders of Janus Global Research Fund in connection with a special meeting of shareholders to be held at the JW Marriott Hotel, 150 Clayton Lane, Denver, Colorado 80206 on March 8, 2013 at 10:00 a.m. Mountain Time (together with any adjournments or postponements thereof, the “Meeting”) to consider a proposal to approve an Agreement and Plan of Reorganization with respect to Janus Global Research Fund (the “Plan”). Under the Plan, all or substantially all of the assets of Janus Global Research Fund (“Global Research Fund”) would be transferred to Janus Worldwide Fund (“Worldwide Fund,” and together with Global Research Fund, the “Funds” and each, a “Fund”), a Fund also managed by Janus Capital Management LLC (“Janus”), in exchange for shares of beneficial interest of Worldwide Fund and the assumption by Worldwide Fund of all of the liabilities of Global Research Fund, as described more fully below (the “Merger”). As a result of the proposed Merger, each shareholder of Global Research Fund will receive a number of full and fractional shares of Worldwide Fund approximately equal in value to their holdings in Global Research Fund as of the closing date of the Merger. The exchange of shares will be conducted at the relative net asset value of the respective Fund shares to be exchanged. After the Merger is completed, Global Research Fund will be liquidated and the combined Fund will be renamed Janus Global Research Fund. The closing of the Merger is contingent upon shareholder approval of the Plan. A copy of the Plan is attached as Appendix A. The Merger is expected to occur on or about March 15, 2013 (the “Closing Date”).

Worldwide Fund and Global Research Fund are each a series of the Trust, an open-end, registered management investment company organized as a Massachusetts business trust. Janus will remain the investment adviser of the combined Fund after the Merger. Janus is responsible for the day-to-day management of Global Research Fund’s and Worldwide Fund’s investment portfolios and furnishes continuous advice and recommendations concerning each Fund’s investments. Janus, which as of September 30, 2012, sponsored 57 mutual funds with approximately $95 billion in mutual fund assets under management, is one of the larger mutual fund sponsors in the United States. The same investment team that currently manages Global Research Fund will continue to manage the combined Fund after the Merger.

The Board of Trustees that oversees the Funds is soliciting proxies from shareholders of Global Research Fund for the Meeting. This Proxy Statement/Prospectus, Notice of Special Meeting, and the proxy card(s) are first being mailed to shareholders on or about December 26, 2012.

The Board of Trustees recommends that shareholders vote FOR the Plan.

This Proxy Statement/Prospectus, which you should read carefully and retain for future reference, sets forth the information that you should know about Global Research Fund, Worldwide Fund, and the proposed Merger, before voting on the Plan and thereby investing in the combined Fund as of the Closing Date. If the Merger is approved, the combined Fund will adopt the investment strategies and policies of your Fund. Both Funds share the same investment objective of long-term growth of capital. In addition, after the Merger, your Fund’s total expenses are expected to decrease as a result of combining with the larger asset base of Worldwide Fund. Janus is also limiting the performance-based management fee rate paid by the combined Fund for three years after the Merger. This will likely mean that the performance-based management fee rate your Fund currently pays will be reduced during the first three years after the Merger. The Prospectus of Worldwide Fund, as supplemented, is enclosed and is incorporated by reference and considered part of this Proxy Statement/Prospectus.

Shares of the Funds have not been approved or disapproved by the SEC nor has the SEC passed upon the accuracy or adequacy of this Proxy Statement/Prospectus. Any representation to the contrary is a criminal offense.

Q&A / SYNOPSIS

This Proxy Statement/Prospectus provides a brief overview of the key features and other matters typically of concern to shareholders considering a proposed merger between mutual funds. These responses are qualified in their entirety by the remainder of this Proxy Statement/Prospectus, which you should read carefully because it contains additional information and further details regarding the Merger. The description of the Merger is qualified by reference to the full text of the Plan, which is attached as Appendix A.

Q.	What is being proposed?
A.	The Board of Trustees of the Trust recommends that shareholders of Global Research Fund approve a plan that authorizes the merger of Global Research Fund into Worldwide Fund. Each Fund is a series of the Trust and is managed by Janus. You are receiving this Proxy Statement/Prospectus because, as a shareholder of Global Research Fund, you have a right to vote on the Merger.

If approved by shareholders, as of the Closing Date, Global Research Fund investors will receive a number of full and fractional shares of Worldwide Fund approximately equivalent in dollar value to their shares held in Global Research Fund as of the close of business on the Closing Date. Specifically, all or substantially all of the assets of Global Research Fund will be transferred to Worldwide Fund solely in exchange for shares of Worldwide Fund with a value approximately equal to the value of Global Research Fund’s assets net of liabilities, and the assumption by Worldwide Fund of all liabilities of Global Research Fund. Immediately following the transfer, the shares of Worldwide Fund received by Global Research Fund will be distributed pro rata to Global Research Fund shareholders of record as of the Closing Date (on or about March 15, 2013). After the Merger is completed, Global Research Fund will be liquidated and the combined Fund will be renamed Janus Global Research Fund. The Merger is conditioned upon receipt of an opinion of counsel that the Merger qualifies as a tax-free Merger.

Q.	What is happening with the Merger?
A.	If approved, the following will occur:

  •  Your Fund (Global Research Fund) will merge into Worldwide Fund, creating the “Combined Fund.”

  •  The Combined Fund will be managed by the investment team that currently manages your Fund.

  •  The Combined Fund will adopt the strategies, investment policies and risks of your Fund.

  •  The Combined Fund will change its name to “Janus Global Research Fund.”

  •  The performance history of Global Research Fund will continue as the Combined Fund’s historical performance.

  •  The Combined Fund will use the expense structure of Worldwide Fund, including maintaining:

¡	the base management fee rate of Worldwide Fund of 0.60%, which is 0.04% lower annually than your Fund, and
¡	the benchmark index of Worldwide Fund, the Morgan Stanley Capital International (“MSCI”) World Indexsm, which will be used for purposes of calculating the Combined Fund’s performance adjustment to the base management fee rather than the MSCI World Growth Index, which is your Fund’s current benchmark.

  •  For three years after the Merger, Janus will waive its management fee to at least a level that is equivalent to the fee rate the Combined Fund would have paid if, after the Merger, the performance history of Worldwide Fund were used to calculate the performance fee adjustment to the base management fee. Essentially, this means that the management fee rate paid by the Combined Fund is expected to be lower than the management fee rate you would pay as a shareholder of Global Research Fund, assuming the performance of each Fund was the same after the Merger.

  •  Your Fund’s total expense ratio (excluding any performance adjustment) is expected to decrease after the Merger as a result of combining assets with the larger Worldwide Fund.

Q.	What is the recommendation of the Board of Trustees?
A.	At a meeting held on August 30, 2012, the Board of Trustees of the Trust (“Board of Trustees,” “Board” or “Trustees”) determined that the Merger is in the best interests of Global Research Fund and Worldwide Fund.
	The Board of Trustees recommends that shareholders vote FOR the Plan.

1

Q.	What did the Board of Trustees consider in determining that the Merger is in the best interests of Global Research Fund?
A.	In determining that the Merger is in the best interests of Global Research Fund, the Board of Trustees considered the following factors, among others:

  •  The compatibility of each Fund’s investment objective, strategies and risks, and the extent of the overlap of portfolio holdings between the Funds.

  •  The portfolio management team that currently manages the Global Research Fund will continue to manage the Combined Fund after the Merger, using the investment strategies and policies of Global Research Fund.

  •  Shareholders of Global Research Fund will have the opportunity to invest in the larger Combined Fund and benefit from long-term economies of scale related to the Fund’s other expenses that are expected to result from the Merger.

  •  The comparative expense structure of the two Funds, including the expectation that expenses for the Combined Fund will be lower for shareholders of Global Research Fund after the Merger. This consideration takes into account the lower base management fee rate (which excludes the performance adjustment) and the three-year fee waiver by Janus implemented with the Merger that is expected to result in a net management fee rate for the Combined Fund during the three-year period that is lower than the one Global Research Fund shareholders would have paid if the Merger did not occur.

  •  The historical performance of Global Research Fund as compared to its current benchmark and to the benchmark of the Combined Fund, and the potential impact on the size of future performance adjustments to the base management fee rate after the three-year waiver expires.

  •  The Merger, for each Fund and its shareholders, is expected to be tax-free in nature.

  •  The Combined Fund may not be able to utilize certain tax loss carry forwards that would otherwise be available.

  •  Janus and Global Research Fund are equally sharing the costs associated with the Merger.

  •  The benefits of the Merger to Janus and its affiliates, including, among other things, that Janus may derive greater operational efficiencies by managing a single fund rather than two separate funds with substantially similar investment objectives, strategies, policies, and risks.

Q. Will I own the same number of shares of the Combined Fund as I currently own of Global Research Fund?

A. No. You will receive the same class of shares of the Combined Fund, and approximately equivalent in dollar value, as the class of shares of Global Research Fund you own as of the Merger. However, the number of shares you receive will depend on the relative net asset values of the shares of Global Research Fund and Worldwide Fund as of the close of trading on the New York Stock Exchange (“NYSE”) on the business day prior to the closing of the Merger.

Q.	How do the Funds’ investment objective, strategies, and risks compare?
A.	The following summarizes the primary similarities and differences in the Funds’ investment objective, principal investment strategies, and risks.
	Similarities:
	Investment Objective:  Each Fund seeks long-term growth of capital.
	Principal Investment Strategies:

  •  Each Fund invests primarily in equity securities selected for their growth potential.

  •  Each Fund can invest in companies of any size located anywhere in the world. Global Research Fund has a formal policy to invest at least 40% of its assets outside the United States. As of September 30, 2012, Global Research Fund held approximately 49.9% of its assets outside the United States and Worldwide Fund held approximately 48.4% of its assets outside the United States.

  •  Each Fund can invest in emerging markets. As of September 30, 2012, Global Research Fund held approximately 3.7% of its assets in emerging markets and Worldwide Fund held approximately 6.9% of its assets in emerging markets.

  •  Each Fund may invest in derivatives.

Diversification:  Each Fund is classified as “diversified,” meaning that the Fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer.

Risks:  Each Fund’s returns will vary and you could lose money. The primary risks of each Fund relate to the market, investments in growth securities, and foreign exposure.

2

Differences:

Portfolio Manager:  Worldwide Fund is managed by George Maris. Global Research Fund is managed by Janus’ equity research analysts, overseen by the Portfolio Oversight Team led by Janus’ Director of Equity Research James Goff. Janus’ equity research analysts select investments for Global Research Fund which represent their high-conviction investment ideas in all market capitalizations, styles, and geographies. For Worldwide Fund, Mr. Maris applies a “bottom up” approach to selecting investments, meaning he looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. If the Merger is approved, Janus’ equity research analysts will manage the Combined Fund and will continue to be led by James Goff.

Benchmarks:  The MSCI World Index^sm is Worldwide Fund’s benchmark and the MSCI World Growth Index is Global Research Fund’s benchmark. Both Funds also compare their performance to a secondary benchmark, the MSCI All Country World Index^sm. If the Merger is approved, Worldwide Fund’s benchmark, the MSCI World Index^sm, will be the Combined Fund’s primary benchmark. If the MSCI World Index^sm does not perform as well as the MSCI World Growth Index, it will be easier for the Combined Fund to outperform the MSCI World Index^sm to a greater extent than the MSCI World Growth Index, thereby having the potential to increase the management fee paid by your Fund beginning in the third year after the Merger. Janus has the opportunity to benefit from increased management fees that may be paid by the Combined Fund if the MSCI World Index^sm does not perform as well as the MSCI World Growth Index. When considering whether to approve this Merger, you should consider the change in benchmarks for measuring performance of the Combined Fund and its potential impact on the management fee you will pay.

Number of Holdings:  As of October 31, 2012, Global Research Fund held 135 securities and Worldwide Fund held 99 securities. Despite this difference in number of holdings, Global Research Fund held 33.3% of its assets in securities that were also held in Worldwide Fund and Worldwide Fund held 48.5% of its assets in securities that were also held in Global Research Fund.

	Further information comparing the investment objectives, strategies, restrictions, and risks is included below under “Summary of the Funds.”
Q.	How do the Funds compare in size?

A. As of October 31, 2012, Global Research Fund’s net assets were approximately $302.8 million and Worldwide Fund’s net assets were approximately $1.9 billion. The asset size of each Fund fluctuates on a daily basis and the asset size of the Combined Fund after the Merger may be larger or smaller than the combined assets of the Funds as of October 31, 2012. More current total net asset information is available at janus.com/advisor/mutual-funds (or janus.com/allfunds if you hold Class D Shares).

Q. How does the fee structure of the Combined Fund after the Merger differ from the current fee structure of my Global Research Fund?

A. The fee structure of the Combined Fund after the Merger is substantially similar to the current fee structure of Global Research Fund, but differs in two important respects in terms of the methodology used to calculate the amount of management fees to be paid. Both Funds utilize a performance-based management fee structure, which is composed of (i) a fixed “base” fee rate and (ii) a performance adjustment to the “base” management fee rate resulting in an increase or decrease by up to 0.15% (assuming constant assets) depending on the Fund’s performance relative to its benchmark index over the prior 36-month rolling period (“Performance Adjustment”).

The first difference between the current fee structure for Global Research Fund and that to be used for the Combined Fund is that while Global Research Fund currently has a fixed “base” fee rate of 0.64%, that rate will decrease to 0.60% for the Combined Fund as a result of the Merger.

The second difference is that the Combined Fund will use a different benchmark index than the one currently used by Global Research Fund to calculate the Performance Adjustment. The Combined Fund will retain Global Research Fund’s historical track record. The Performance Adjustment will be calculated by comparing the Combined Fund’s relative performance to MSCI World Index^sm instead of the MSCI World Growth Index. As discussed below, this change will have no practical impact on the management fee rate paid by the Combined Fund for the first three years after the Merger, because Janus has agreed to waive fees to a level determined as if the Performance Adjustment were calculated using the historical performance of Worldwide Fund. If the management fee rate for any month during the three-year waiver period would have been lower using

3

the historical performance of Worldwide Fund for periods prior to the Merger, Janus will waive its fee that month to the lower amount.

To illustrate, assume the Merger occurred on September 30, 2012 when Worldwide Fund’s management fee rate (including the Performance Adjustment) was 0.59% and Global Research Fund’s management fee rate was 0.74% (including the Performance Adjustment). Janus would waive the management fee rate as of the Merger date to the extent that it increased above 0.59%, and for each month during the next three years Janus would continue to waive the management fee rate if the fee rate that Worldwide Fund would have paid was lower than the Combined Fund’s actual management fee rate. Since the Performance Adjustment is calculated based on the historical performance of the Fund over a 36-month rolling period and Worldwide Fund has underperformed Global Research Fund relative to their respective benchmarks during more of the 36-month period, it is expected that the management fee rate paid by your Fund will be reduced during most, if not all, of the three-year period after the Merger. Since the Performance Adjustment fluctuates monthly, the amount of the management fee rate that the Combined Fund will pay and that Janus will waive will also fluctuate monthly.

Pro forma fee, expense, and financial information is included in this Proxy Statement/Prospectus. For additional details related to the performance fee calculation, please refer to Appendix E.

Q. Will the Merger result in higher management fees for current Global Research Fund shareholders?

A. For the first three years after the Merger, the management fee rate you will pay as a shareholder of the Combined Fund will likely be less than the rate you would pay if the Merger did not take place. That’s because the annual “base” portion of the management fee paid by the Combined Fund will decrease from the 0.64% rate you currently pay to a rate of 0.60%, and Janus has agreed to a three-year fee waiver that, as a practical matter, is expected to eliminate most if not all of the impact of the use of the historical performance of Global Research Fund and the MSCI World Index^sm as the Combined Fund’s benchmark index for purposes of calculating the Performance Adjustment. That means while the fee waiver is in effect, you will likely pay less in management fees as a shareholder in the Combined Fund than if the Merger did not take place. However, when the waiver is removed, the management fee rate paid by the Combined Fund will reflect the actual performance of the Combined Fund relative to the MSCI World Index^sm during the 36 months prior to that date, which could be higher or lower than the management fee rate paid monthly during the three-year waiver period. To the extent the Combined Fund outperforms the MSCI World Index^sm after the date of the Merger you could see an increase, and possibly a significant increase, in the management fee rate paid to Janus by the Combined Fund when the waiver is eliminated. That increase would also mean that Janus could earn more in management fees going forward than it otherwise would if the Merger had not occurred. In addition, the three-year waiver could initially result in better performance for the Combined Fund. However, once the waiver is removed, the management fee rate may be higher than it would have been without the three-year waiver. This could result if the Combined Fund outperforms the MSCI World Index^sm to a greater extent during the three-year waiver period as a result of the waiver.

Further, the historical performance of Global Research Fund has typically outperformed the MSCI World Indexsm to a greater extent than it has outperformed the current benchmark index for the Global Research Fund, which means it theoretically would be easier for Janus to earn a higher management fee rate. However, whether this outperformance continues will depend on the performance of the Combined Fund relative to the MSCI World Indexsm, which is not possible to predict.

Q.

Will the Merger result in higher Fund expenses?

A. Fund expenses are expected to be lower for shareholders of Global Research Fund after the Merger. Based on September 30, 2012 assets (and assuming the Merger occurred on September 30, 2012), all classes of Global Research Fund are expected to experience a decrease in Total Annual Fund Operating Expenses, some a significant decrease, without taking into account any waivers or reimbursements.

	Additional pro forma fee, expense, and financial information is included in this Proxy Statement/Prospectus.
Q.	How will the Fund’s performance be shown after the Merger?
A.	The performance of the Combined Fund that is shown after the Merger will be that of Global Research Fund rather than Worldwide Fund. Global Research Fund commenced operations in February 2005 and Worldwide Fund commenced operations in April 1991. By using Global Research Fund’s performance after the Merger, Worldwide Fund’s accounting history is eliminated and replaced by the accounting history of Global Research Fund. Information comparing each Fund’s historical performance is included in this Proxy Statement/Prospectus.

Q. What are the federal income tax consequences of the Merger?

A. The Merger is expected to qualify as a tax-free transaction for federal income tax purposes (under section 368(a) of the Internal Revenue Code of 1986, as amended) and will not take place unless counsel provides an opinion to that effect. Shareholders should not recognize any capital gain or loss as a direct result of the Merger. You may receive a regular distribution towards the end of the 2012 calendar year. However, in order to effect the Merger as a tax-free transaction, prior to the Closing Date you may receive an additional distribution of ordinary income or capital gains that Global Research Fund has accumulated as of the date of the distribution. Additionally, as a result of the Merger, the Combined Fund may lose the ability to utilize a portion of realized capital losses that Global Research Fund might have used absent the Merger to offset or defer gains on sales of portfolio securities under some circumstances. As always, if you choose to redeem or exchange your shares (whether before or after the Merger), you may realize a taxable gain or loss depending on the performance of such shares since you acquired them; therefore, consider consulting a tax adviser before any exchange or redemption.

Q. Will my cost basis change as a result of the Merger?

A. Your total cost basis is not expected to change as a result of the Merger. However, since the number of shares you hold after the Merger is expected to be different than the number of shares you held prior to the Merger, your average cost basis per share may change. Since the Merger will be treated as a tax-free transaction for Global Research Fund, shareholders should not recognize any capital gain or loss as a direct result of the Merger.

Q.	Will the shareholder services provided by Janus change?
A.	No. Janus currently manages both Global Research Fund and Worldwide Fund and will continue as the investment adviser of the Combined Fund following the Merger. The administrator, custodian, transfer agent, and distributor are the same for the Funds and will not change as a result of the Merger. Shareholders of Global Research Fund will also have the same purchase and redemption privileges as they currently enjoy. Please consult your financial intermediary for information on any services provided by them to the Funds.
Q.	Will there be any sales load, commission or other transactional fee in connection with the Merger?
A.	No. There will be no sales load, commission or other transactional fee in connection with the Merger. The full and fractional value of shares of Global Research Fund will be exchanged for full and fractional corresponding shares of the Combined Fund having approximately equal value, without any sales load, commission or other transactional fee being imposed.
Q.	Can I still add to my existing Global Research Fund account until the Merger?

A. Yes. Global Research Fund shareholders may continue to make additional investments until the Closing Date (anticipated to be on or about March 15, 2013), unless the Board of Trustees determines to limit future investments to ensure a smooth transition of shareholder accounts or for any other reason. If the Merger is approved, an account in the Combined Fund will be set up in your name and your shares of Global Research Fund will automatically be converted to corresponding shares of the Combined Fund. You will receive confirmation of this transaction following the Merger.

Q. Will either Fund pay fees associated with the Merger?

A. Fees associated with the Merger are shared equally between Janus and Global Research Fund. Such fees are estimated to be $300,000 plus any out-of-pocket expenses.

Q. If shareholders approve the Merger, when will the Merger take place?

A. If approved, the Merger is expected to occur on or about March 15, 2013, or as soon as reasonably practicable after shareholder approval is obtained. After completion of the Merger, affected shareholders will receive a confirmation statement reflecting their new Fund account number and number of shares owned.

Q. What if I want to exchange my shares into another Janus fund prior to the Merger?

A. You may exchange your shares into another Janus fund before the Closing Date (on or about March 15, 2013) in accordance with your pre-existing exchange privileges by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus representative at 1-800-525-3713 if you hold Class D Shares or 1-800-525-0020 if you hold shares through an intermediary. If you choose to exchange your shares of Global Research Fund for another Janus fund, your request will be treated as a normal exchange of shares and will be a taxable transaction unless your shares are held in a tax-deferred account, such as an individual retirement account (“IRA”). Exchanges may be subject to minimum investment requirements.

5

Q. What happens if the Merger is not approved?

A. If the Merger is not approved, any shares you held in Global Research Fund would remain Global Research Fund shares. Global Research Fund and Worldwide Fund would each continue to operate separately and the Board of Trustees would determine what further action, if any, to take.

Q. How many votes am I entitled to cast?

A. You are entitled to one vote for each whole dollar value or a proportionate fractional vote for each fractional dollar value of the net asset value of Global Research Fund shares held in your name on the Record Date. Shareholders of record of Global Research Fund at the close of business on the Record Date will receive notice of and be asked to vote on the Plan.

Q.	How can I vote my shares?
A.	You can vote in any one of four ways:

  •  By mail, by sending the enclosed proxy card (signed and dated) in the enclosed envelope;

  •  Through the internet by going to the website listed on your proxy card;

  •  By telephone using the toll-free number listed on your proxy card; or

  •  In person, by attending the Special Meeting of Shareholders on March 8, 2013 (or any adjournments or postponements thereof).

	Whichever method you choose, please take the time to read the full text of this Proxy Statement/Prospectus before you vote.
Q.	If I vote my proxy now as requested, can I change my vote later?
A.	Yes. You may revoke your proxy vote at any time before it is voted at the Meeting by (1) delivering a written revocation to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206; (2) submitting a subsequently executed proxy vote; or (3) attending the Meeting and voting in person. Even if you plan to attend the Meeting, we ask that you return the enclosed proxy card or vote by telephone or the internet. This will help us to ensure that an adequate number of shares are present at the Meeting for consideration of the Merger.
Q.	What is the required vote to approve the Merger?
A.	Approval of the Merger will require the affirmative vote of a “majority of the outstanding voting securities” of Global Research Fund within the meaning of the Investment Company Act of 1940, as amended (the “1940 Act”). This means the lesser of (1) 67% or more of the shares present at the Meeting if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (2) more than 50% of the outstanding shares.
Q.	Whom should I call for additional information about this Proxy Statement/Prospectus?

A. Please call Computershare, your Fund’s information agent (proxy solicitor), at 1-866-492-0863.

SUMMARY OF THE FUNDS

This section provides a summary of each Fund, including but not limited to, each Fund’s investment objective, fees and expenses, primary investment strategies and risks, and historical performance. Please note that this is only a brief discussion and is qualified in its entirety by reference to the complete information contained herein, including the Funds’ prospectuses which are incorporated by reference. There is no assurance that a Fund will achieve its stated objective. Both Funds are designed for long-term investors who primarily seek growth of capital and who can tolerate the greater risks associated with common stock investments. If the Merger is approved, the Combined Fund will adopt the investment strategies and policies of Global Research Fund, and the Janus equity research analysts, overseen by the Portfolio Oversight Team led by Janus’ Director of Equity Research James Goff, will serve as the investment personnel managing the Combined Fund.

Investment Objective

Each Fund seeks long-term growth of capital.

Comparison of Fees and Expenses

The types of expenses currently paid by each class of shares of Global Research Fund are the same types of expenses paid by the corresponding share classes of Worldwide Fund. Currently, the Funds each have a management fee rate that fluctuates up and

6

down monthly based on the performance of the Fund relative to its benchmark index. For Worldwide Fund, the management fee is calculated by applying a performance adjustment of up to 0.15% (positive or negative) based on Worldwide Fund’s performance relative to the MSCI World Index^sm over the prior 36 months to an annual fixed rate of 0.60%. For Global Research Fund, the management fee is calculated by applying a Performance Adjustment of up to 0.15% (positive or negative) based on Global Research Fund’s performance relative to the MSCI World Growth Index over the prior 36 months to an annual fixed rate of 0.64%. If the Merger is approved, the Combined Fund will charge an annual base management fee rate of 0.60% and apply a Performance Adjustment to that rate of up to 0.15% (positive or negative) (assuming constant assets) based on the performance of Global Research Fund relative to the MSCI World Index^sm for periods prior to the Merger date, and performance of the Combined Fund relative to the MSCI World Index^sm for periods after the Merger date. The performance of Global Research Fund for periods prior to the Merger date replaces the performance of Worldwide Fund over those same periods, as Global Research Fund is the performance and accounting survivor for the Merger. Global Research Fund has historically outperformed Worldwide Fund and the MSCI World Index^sm to a greater extent than Worldwide Fund. Since the performance fee paid to Janus is based on the performance of the Fund over a rolling 36-month period, this means that shareholders of Worldwide Fund would experience an increase in the Performance Adjustment to the management fee immediately after the date of the Merger. Therefore, for three years after the Merger, Janus will waive the management fee rate paid by the Combined Fund to the lower of (i) the actual management fee rate using Global Research Fund’s performance and assets for periods prior to the Merger to calculate the Performance Adjustment, or (ii) the management fee rate that would have been paid if Worldwide Fund’s performance and larger assets were used to calculate the Performance Adjustment for periods prior to the Merger.

Current and Pro Forma Fees and Expenses

The following tables compare the fees and expenses you may bear directly or indirectly as an investor in Global Research Fund versus Worldwide Fund, and show the projected (“pro forma”) estimated fees and expenses of the Combined Fund, assuming consummation of the Merger as of September 30, 2012. Fees and expenses shown for Global Research Fund and Worldwide Fund were determined based on each Fund’s average net assets as of the fiscal year ended September 30, 2012. Total net assets as of September 30, 2012 were $305,687,109 for Global Research Fund and $1,918,851,403 for Worldwide Fund.

The pro forma fees and expenses are estimated in good faith and are hypothetical, and do not include any change in expense ratios resulting from a change in assets under management since September 30, 2012 for either Fund. More current total net asset information is available at janus.com/advisor/mutual-funds (or janus.com/allfunds if you hold Class D Shares). It is important for you to know that a decline in a Fund’s average net assets during the current fiscal year and after the Merger, as a result of market volatility or other factors, could cause the Fund’s expense ratio to be higher than the fees and expenses shown, which means you could pay more if you buy or hold shares of the Funds. Global Research Fund is also paying half of the fees related to the Merger, which are shown in a footnote to the table below.

Annual Fund Operating Expenses

Annual Fund Operating Expenses are paid out of a Fund’s assets and include fees for portfolio management, administration and administrative services, including recordkeeping, accounting or subaccounting, and other shareholder services. You do not pay these fees directly, but as the examples in the table below show, these costs are borne indirectly by all shareholders.

The Annual Fund Operating Expenses shown in the table below represent annualized expenses for Global Research Fund and for Worldwide Fund as well as those estimated for the Combined Fund on a pro forma basis, assuming consummation of the Merger, for the fiscal year ended September 30, 2012.

Expense Limitations

Total Annual Fund Operating Expenses After Fee Waiver shown in the table below reflects two separate expense limits agreed to by Janus. First, pursuant to a contract between Janus and each of Global Research Fund and Worldwide Fund, currently through at least February 1, 2014, Janus reduces operating expenses, including its management fee rate (prior to any Performance Adjustment) paid by each Fund, by the amount by which the total annual fund operating expenses allocated to any class of the Fund exceed 1.07% of average daily net assets. For purposes of this waiver, operating expenses do not include distribution and shareholder servicing (12b-1) fees, administrative services fees, including transfer agency fees payable pursuant to the Transfer Agency Agreement, Performance Adjustments, acquired fund fees and expenses, or items not normally considered operating expenses, such as interest, dividends, taxes, brokerage commissions, and extraordinary expenses (including, but not limited to, legal claims and liabilities and litigation costs, and any related indemnification).

7

Second, Janus has also agreed to waive the Performance Adjustment to the management fee to a level that is at least that of the management fee rate paid by Worldwide Fund by using Worldwide Fund’s performance history for periods prior to the Merger and comparing it to the performance fee of the Combined Fund (which is based on Global Research Fund’s performance history for periods prior to the Merger) to determine the amount of any waiver. Essentially, the management fee rate paid by the Combined Fund will be the lower of (i) the actual management fee rate using Global Research Fund’s performance and assets for periods prior to the Merger to calculate the Performance Adjustment, or (ii) the management fee rate that would have been paid if Worldwide Fund’s performance and larger assets were used to calculate the Performance Adjustment for periods prior to the Merger. This waiver (which extends for three years after the Merger) is included in the Total Annual Fund Operating Expenses After Fee Waiver shown in the table, assuming the Merger occurred on September 30, 2012. The waiver will adjust monthly.

Changes to expenses and asset levels of either Global Research Fund or Worldwide Fund or both between the date of this Proxy Statement/Prospectus and the Merger date could impact the net expenses shown below that will be paid by the Combined Fund.

EXAMPLES:

The following Examples are based on expenses without waivers. These Examples are intended to help you compare the cost of investing in Global Research Fund, Worldwide Fund, and the Combined Fund after the Merger with the cost of investing in other mutual funds. The Examples assume that you invest $10,000 in Global Research Fund, Worldwide Fund, and the Combined Fund after the Merger for the time periods indicated and reinvest all dividends and distributions. The Examples also assume that your investment has a 5% return each year and that the Funds’ operating expenses without waivers remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

(1) All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

(2) The “Management Fee” is the management fee rate paid by each Fund to Janus under each Investment Advisory Agreement as of September 30, 2012. Global Research Fund and Worldwide Fund each pay a management fee rate that adjusts up or down by a variable of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This fee rate, prior to any Performance Adjustment, is 0.64% for Global Research Fund and 0.60% for Worldwide Fund. If the Merger is approved, the Combined Fund will continue to charge an annual base management fee rate of 0.60% and apply a Performance Adjustment to that rate of up to 0.15% (positive or negative) (assuming constant assets) based on the performance of Global Research Fund relative to the MSCI World Index^sm, for periods prior to the Merger and performance of the Combined Fund beginning as of the Merger date. The management fee shown for the Combined Fund does not reflect any waivers by Janus. These waivers are reflected under “Total Annual Fund Operating Expenses After Fee Waiver.” Refer to “Management Expenses” section in this Proxy Statement/Prospectus for additional information with further description in the Funds’ Statement of Additional Information, as supplemented, which is incorporated by reference herein.

(3) If applicable to the share class, because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.

(4) “Other Expenses” for Class A Shares, Class C Shares, and Class I Shares may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds. “Other Expenses” for Class S Shares and Class T Shares include an administrative services fee of up to 0.25% of the average daily net assets of each class to compensate Janus Services LLC (“Janus Services”), the Funds’ transfer agent, for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels. “Other Expenses” for Class D Shares include an administrative services fee of 0.12% of the average daily net assets of Class D Shares for shareholder services provided by Janus Services, the Funds’ transfer agent. “Other Expenses” for all classes may include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. If applicable, such amounts are less than 0.01%. “Other Expenses” for all classes may include reimbursement to Janus of its out-of-pocket costs for services as administrator and to Janus Services of its out-of-pocket costs for serving as transfer agent and providing, or arranging by others the provision of, servicing to shareholders.

(5) Janus has contractually agreed to waive each Fund’s total annual fund operating expenses (excluding any Performance Adjustments to management fees, the distribution and shareholder servicing fees, administrative services fees payable pursuant to the Transfer Agency Agreement, brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) to 1.07% for each Fund, until at least February 1, 2014. The contractual waiver may be terminated or modified prior to this date only at the discretion of the Board of Trustees. For the Combined Fund, Janus has also agreed to waive the

11

Performance Adjustment to the management fee as described in this Proxy Statement/Prospectus. Application of the expense waivers and their effect on annual fund operating expenses is reflected, when applicable, under “Total Annual Fund Operating Expenses After Fee Waiver” in the table. As previously noted, Global Research Fund is paying half of the fees related to the Merger. If those expenses were included in the table, the Total Annual Fund Operating Expenses would be 1.27% for Class A Shares, 2.11% for Class C Shares, 1.08% for Class D Shares, 1.43% for Class S Shares, 1.02% for Class I Shares, and 1.17% for Class T Shares.

(6)	Assumes the payment of the maximum initial sales charge on Class A Shares at the time of purchase for the Funds. The sales charge may be waived or reduced for certain investors, which would reduce the expenses for those investors.
(7)	A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example.

(8) A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in Appendix C.

(9) Contingent deferred sales charge is not applicable.

Portfolio Turnover

Each Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Examples, affect the Funds’ performance. During the most recent fiscal year, Global Research Fund’s portfolio turnover rate was 67% of the average value of its portfolio and Worldwide Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Principal Investment Strategies

Worldwide Fund has substantially similar investment strategies to those of Global Research Fund. Each Fund pursues its investment objective by investing primarily in equity securities selected for their growth potential. The primary differences between the Funds are that Global Research Fund has a formal policy to invest at least 40% of its assets outside the United States while Worldwide Fund invests in issuers from several different countries, including the United States, and investments for Global Research Fund are selected by the Janus equity research analysts, overseen by the Portfolio Oversight Team led by Janus’ Director of Equity Research, versus a single portfolio manager for Worldwide Fund. Even though the investment strategies are substantially similar, the manner in which investments are selected by the Funds may differ and result in differences in individual securities between the Funds and differences in weightings of securities that overlap between the Funds.

The following is intended to show the differences between the Funds’ principal investment strategies, and also show the investment strategies of the Combined Fund, post-Merger, which are the same as Global Research Fund’s current strategies. This information is qualified in its entirety by the prospectus of each Fund, which is incorporated by reference.

For additional information on the Funds’ principal investment strategies and related risks, please refer to the “Additional Information About the Funds” section of this Proxy Statement/Prospectus and Appendix C.

Principal Investment Risks

Each Fund invests primarily in equity securities and may invest in various types of equity securities or use certain investment techniques to achieve its investment objective. The following is a summary of the principal risks associated with such securities and investment techniques. Because each Fund has the same investment objective, and substantially similar investment strategies and policies, the principal risks are generally the same for each Fund. Additional information about these risks is included below and described in greater detail later in this Proxy Statement/Prospectus under “Additional Information About the Funds – Additional Risks of the Funds.’’ As with any security, an investment in either Fund involves certain risks, including loss of principal. The fact that a particular risk is not identified does not mean that a Fund, as part of its overall investment strategy, does not invest or is precluded from investing in securities that give rise to that risk.

The biggest risk is that a Fund’s returns will vary, and you could lose money. Each Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk.  Each Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where a Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Funds’ investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk.  The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than

13

investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Funds’ investments. In addition, each Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Additionally, foreign and emerging market risks, including but not limited to price controls, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, nationalization, and restrictions on repatriation of assets may be heightened to the extent a Fund invests in Chinese local market equity securities (also known as “A Shares”). Some of the risks of investing directly in foreign and emerging market securities may be reduced when a Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve other risks. As of September 30, 2012, approximately 3.7% of Global Research Fund’s investments were in emerging markets. As of September 30, 2012, approximately 6.9% of Worldwide Fund’s investments were in emerging markets.

Market Risk.  The value of each Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s or investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of each Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk.  Each Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s and/or investment personnel’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities. Global Research Fund currently compares and broadly matches its sector weights to those of a growth-based index. If growth stocks are out of favor, sectors that are larger in a growth index may underperform, leading to Fund underperformance relative to other indices less biased toward growth stocks. If the Merger is approved, the Combined Fund will compare and broadly match its sector weights to those of the MSCI World Index^sm rather than the MSCI World Growth Index, meaning the selection of growth stocks will be measured against a different benchmark than your Fund currently does today and the different sector weights could change the risk profiles of your Fund.

Derivatives Risk.  Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.

An investment in a Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Comparison of Fund Performance

The following information provides some indication of the risks of investing in each Fund by showing how each Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of each Fund commenced operations on February 25, 2005, for Global Research Fund, and May 15, 1991, for Worldwide Fund. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of each Fund commenced operations on July 6, 2009. Class D Shares of each Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. Worldwide Fund also offers Class R Shares, but such shares are not offered by Global Research Fund.

14

•  The performance shown for Class T Shares of each Fund is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class A Shares, Class C Shares, and Class S Shares of each Fund for periods prior to July 6, 2009, reflects the performance of each Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.

•  The performance shown for Class I Shares of each Fund for periods prior to July 6, 2009, reflects the performance of each Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class D Shares of each Fund for periods prior to February 16, 2010, reflects the performance of each Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of each Fund had been available during periods prior to July 6, 2009, or Class D Shares of each Fund had been available during periods prior to February 16, 2010, the performance shown for each respective share class may have been different. The performance shown for periods following each Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class D Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar charts depict the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of a Fund. If sales charges were included, the returns would be lower. The table following each Fund’s bar chart compares each Fund’s average annual returns for the periods indicated to broad-based securities market indices (which, unlike the Funds, do not have any fees or expenses). Global Research Fund’s performance is compared to the MSCI World Growth Index and the MSCI All Country World Index^sm (the Fund’s secondary benchmark). Worldwide Fund’s performance is compared to the MSCI World Index^sm and the MSCI All Country World Index^sm (the Fund’s secondary benchmark). After the Merger, the Combined Fund will compare its performance to the MSCI World Index^sm, with the MSCI All Country World Index^sm as the Fund’s secondary benchmark. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Funds’ performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Funds’ past performance (before and after taxes) does not necessarily indicate how they will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687 (or at janus.com/allfunds or by calling 1-800-525-3713 if you hold Class D Shares).

(1)	If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
(2)	Calculated assuming maximum permitted sales loads.
(3)	The one year return is calculated to include the contingent deferred sales charge.

After-tax returns are calculated using distributions for each Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

After-tax returns are only shown for Class T Shares of the Funds. After-tax returns for the other classes of shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Management of the Funds

Investment Adviser:  Janus is the investment adviser for each Fund and will remain the investment adviser of the Combined Fund after the Merger.

Portfolio Management:  James P. Goff, CFA, is Janus’ Director of Equity Research and Executive Vice President of Global Research Fund, which he has managed since inception.

Portfolio Manager:  George P. Maris, CFA, is Executive Vice President and Portfolio Manager of Worldwide Fund, which he has managed since March 2011.

If the Merger is approved, the Combined Fund will be managed by Janus’ equity research analysts, overseen by the Portfolio Oversight Team led by Janus’ Director of Equity Research James Goff. Additional detail about management of the Funds is included later in this Proxy Statement/Prospectus.

Tax Information

Each Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of a Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another.

THE MERGER

The Plan

Shareholders of Global Research Fund are being asked to approve the Plan, which sets forth the terms and conditions under which the Merger will be implemented. Significant provisions of the Plan are summarized below; however, this summary is qualified in its entirety by reference to the Plan, which is attached hereto as Appendix A to this Proxy Statement/Prospectus.

The Plan contemplates: (i) Worldwide Fund’s acquisition of all or substantially all of the assets of Global Research Fund in exchange solely for shares of Worldwide Fund and the assumption by Worldwide Fund of all of Global Research Fund’s liabilities, if any, as of the Closing Date; (ii) the distribution on the Closing Date of those shares to the shareholders of Global Research Fund; and (iii) the complete liquidation of Global Research Fund.

The value of Global Research Fund’s assets to be acquired and the amount of its liabilities to be assumed by Worldwide Fund and the net asset value (“NAV”) of a share of Global Research Fund will be determined as of the close of regular trading on the NYSE on the Closing Date, after the declaration by Global Research Fund of distributions, if any on the Closing Date, and will be determined in accordance with the valuation methodologies described in Global Research Fund’s currently effective Prospectuses and Statement of Additional Information, as supplemented (“SAI”). The Plan provides that Janus and Global Research Fund will equally share the fees and costs related the Merger, including the costs and expenses incurred in the preparation and mailing of this Proxy Statement/Prospectus. The Closing Date is expected to be on or about March 15, 2013.

As soon as practicable after the Closing Date, Global Research Fund will distribute pro rata to its shareholders of record the shares of Worldwide Fund it receives in the Merger, so that each shareholder of Global Research Fund will receive a number of full and fractional shares of Worldwide Fund approximately equal in value to his or her holdings in Global Research Fund, and Global Research Fund will be liquidated. The exchange of shares will be conducted at the relative net asset value of the respective Fund shares to be exchanged.

Such distribution will be accomplished by opening accounts on the books of Worldwide Fund in the names of Global Research Fund shareholders and by transferring to those accounts the shares of Worldwide Fund previously credited to the account of Global Research Fund on those books. Each shareholder account shall be credited with the pro rata number of Worldwide Fund’s shares due to that shareholder. All issued and outstanding shares of Global Research Fund will simultaneously be canceled on the books of the Trust. Accordingly, immediately after the Merger, each former shareholder of Global Research Fund will own shares of Worldwide Fund that will be approximately equal to the value of that shareholder’s shares of Global Research Fund as of the Closing Date. Any special options will automatically transfer to the new fund accounts.

The implementation of the Merger is subject to a number of conditions set forth in the Plan, including approval by shareholders of Global Research Fund. The Plan also requires receipt of a tax opinion indicating that, for federal income tax purposes, the Merger qualifies as a tax-free Merger. The Plan may be terminated and the Merger abandoned at any time prior to the Closing Date by the Board of Trustees if the Trustees determine that the Merger is not in the best interests of the Funds’ shareholders. Please review the Plan carefully.

Reasons for the Merger

The Merger is part of an effort by Janus in reviewing its product line-up to provide the potential for both meaningful short- and long-term benefits to Fund shareholders, including clearer product differentiation, a reduction in overlapping offerings, and a resulting larger, more stable asset base. The Funds have the same investment objective and substantially similar principal investment strategies, policies, and risks. The Merger has the potential to increase operational efficiencies, including the elimination of duplicative costs and other inefficiencies that can arise from having comparable mutual funds in the same family

20

of funds. Janus and its affiliates that provide services to the Funds expect to provide the same level of services to shareholders of the Combined Fund after the Merger.

Janus met with the Trustees, none of whom are considered “interested persons” (as defined in the 1940 Act) (“Independent Trustees”), on June 19, 2012, August 1, 2012, August 10, 2012, and August 30, 2012, to discuss Janus’ proposal to merge the Funds. At each meeting, the Independent Trustees also discussed this proposal and the Plan with their independent counsel in executive session. During the course of these meetings, the Trustees requested and considered such information as they deemed relevant to their deliberations.

At the meeting of the Board of Trustees of the Trust held on August 30, 2012, the Trustees approved the Plan after determining that (1) the Merger is in the best interests of Global Research Fund; and (2) the Merger will not dilute the interests of existing shareholders of either Fund. The Trustees determined that the Plan should be submitted to shareholders of Global Research Fund for their approval. In making their determination that the Merger is in the best interests of Global Research Fund, the Trustees considered the following factors, among others:

•  The compatibility of each Fund’s investment objective, strategies and risks, and the extent of the overlap of portfolio holdings between the Funds.

•  The portfolio management team that currently manages the Global Research Fund will continue to manage the Combined Fund after the Merger, using the investment strategies and policies of Global Research Fund.

•  Shareholders of Global Research Fund will have the opportunity to invest in the larger Combined Fund and benefit from long-term economies of scale related to the Fund’s other expenses that are expected to result from the Merger.

•  The comparative expense structure of the two Funds, including the expectation that expenses for the Combined Fund will be lower for shareholders of Global Research Fund after the Merger. This consideration takes into account the lower base management fee rate (which excludes the Performance Adjustment) and the three-year fee waiver by Janus implemented with the Merger that is expected to result in a net management fee rate for the Combined Fund during the three-year period that is lower than the one Global Research shareholders would have paid if the Merger did not occur.

•  The historical performance of Global Research Fund as compared to its current benchmark and to the benchmark of the Combined Fund, and the potential impact on the size of future Performance Adjustments to the base management fee rate after the three-year waiver expires.

•  The Merger, for each Fund and its shareholders, is expected to be tax-free in nature.

•  The Combined Fund may not be able to utilize certain tax loss carry forwards that would otherwise be available.

•  Janus and Global Research Fund are equally sharing the costs associated with the Merger.

•  The benefits of the Merger to Janus and its affiliates, including, among other things, that Janus may derive greater operational efficiencies by managing a single fund rather than two separate funds with substantially similar investment objectives, strategies, policies, and risks.

The Board of Trustees recommends that shareholders vote FOR approval of the Plan to authorize the Merger.

Federal Income Tax Consequences

As a condition to the Merger, the Trust will receive a legal opinion from Dechert LLP, special counsel to Janus, subject to customary assumptions and representations, on the basis of the existing provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the Treasury Regulations promulgated thereunder and current administrative and judicial interpretations thereof, for federal income tax purposes substantially to the effect that:

•  the transfer of all or substantially all of the assets of Global Research Fund solely in exchange for shares of Worldwide Fund and the assumption by Worldwide Fund of all liabilities of Global Research Fund, and the distribution of such shares to the shareholders of Global Research Fund, will constitute a “reorganization” within the meaning of Section 368(a) of the Code;

•  no gain or loss will be recognized by Global Research Fund on the transfer of the assets of Global Research Fund to Worldwide Fund in exchange for Worldwide Fund shares or the assumption by Worldwide Fund of all liabilities of Global Research Fund or upon the distribution of Worldwide Fund shares to Global Research Fund shareholders in exchange for their shares of Global Research Fund, except that Global Research Fund may be required to recognize gain or loss with respect to contracts described in Section 1256(b) of the Code or stock in a passive foreign investment company, as defined in Section 1297(a) of the Code;

•  the tax basis of Global Research Fund’s assets acquired by Worldwide Fund will be the same to Worldwide Fund as the tax basis of such assets to Global Research Fund immediately prior to the Merger, and the holding period of the assets of Global

21

Research Fund in the hands of Worldwide Fund will include the period during which those assets were held by Global Research Fund;

•  no gain or loss will be recognized by Worldwide Fund upon the receipt of the assets of Global Research Fund solely in exchange for Worldwide Fund shares and the assumption by Worldwide Fund of all liabilities of Global Research Fund;

•  no gain or loss will be recognized by shareholders of Global Research Fund upon the receipt of Worldwide Fund shares by such shareholders, provided such shareholders receive solely Worldwide Fund shares (including fractional shares) in exchange for their Global Research Fund shares; and

•  the aggregate tax basis of Worldwide Fund shares, including any fractional shares, received by each shareholder of Global Research Fund pursuant to the Merger will be the same as the aggregate tax basis of Global Research Fund shares held by such shareholder immediately prior to the Merger, and the holding period of Worldwide Fund shares, including fractional shares, to be received by each shareholder of Global Research Fund will include the period during which Global Research Fund shares exchanged were held by such shareholder (provided that Global Research Fund shares were held as a capital asset on the Closing Date).

The receipt of such an opinion is a condition to the consummation of the Merger. The Trust has not obtained an Internal Revenue Service (“IRS”) private letter ruling regarding the federal income tax consequences of the Merger, and the IRS is not bound by advice of counsel. If the transfer of the assets of Global Research Fund in exchange for Worldwide Fund shares and the assumption by Worldwide Fund of all liabilities of Global Research Fund does not constitute a tax-free Merger, each Global Research Fund shareholder generally will recognize a gain or loss approximately equal to the difference between the value of Worldwide Fund shares such shareholder acquires and the tax basis of such shareholder’s Global Research Fund shares.

Prior to the Closing Date, Global Research Fund may pay to its shareholders a cash distribution consisting of any undistributed investment company taxable income and/or any undistributed realized net capital gains, including any gains realized from any sales of assets prior to the Closing Date, which may be, but is likely not to be, attributable to portfolio transitioning. This distribution would be taxable to shareholders that are subject to tax.

Shareholders of Global Research Fund should consult their tax advisers regarding the effect, if any, of the Merger in light of their individual circumstances. Since the foregoing discussion relates only to the federal income tax consequences of the Merger, shareholders of Global Research Fund should also consult tax advisers as to state and local tax consequences, if any, of the Merger.

As of September 30, 2012, Global Research Fund had accumulated capital loss carryforwards of $20,587,631, of which $19,864,758 may expire on September 30, 2017. After the Merger, these losses may be available to the Combined Fund, which had accumulated capital loss carryforwards of $976,572,347 on September 30, 2012. The final amount of the accumulated capital loss carryforwards for Global Research Fund and Worldwide Fund is subject to change and will not be determined until the time of the Merger. After and as a result of the Merger, any accumulated capital loss carryforwards may in part be subject to limitations under applicable tax laws. As a result, the Combined Fund may not be able to use some or all of these losses, if any, as quickly as each Fund may have used these losses in the absence of the Merger, and part of these losses, if any, may not be useable at all. It is possible to fully utilize the $19,864,758 in capital loss carryforwards for Global Research Fund by September 30, 2017. The Board of Trustees of the Trust took this factor into account in concluding that the Merger would be in the best interests of the Funds.

Securities to Be Issued, Key Differences in Shareholder Rights

Global Research Fund and Worldwide Fund are organized as separate series of the Trust, a Massachusetts business trust, and are governed by the same Amended and Restated Agreement and Declaration of Trust dated March 18, 2003, as amended from time to time (“Trust Instrument”) and Bylaws. As such, there are no key differences in the rights of shareholders of the Funds.

ADDITIONAL INFORMATION ABOUT THE FUNDS

Additional Investment Strategies and General Portfolio Policies

Each Fund’s investment objective is long-term growth of capital. The Funds’ Board of Trustees may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to a Fund’s objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.

Unless otherwise stated, the following additional investment strategies and general policies apply to each Fund and provide further information including, but not limited to, the types of securities a Fund may invest in when implementing its investment objective. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. Except for the Funds’ policies with respect to investments in illiquid securities and borrowing, the percentage

23

limitations included in these policies and elsewhere in this Proxy Statement/Prospectus and/or the Funds’ SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities.

Cash Position

The Funds may not always stay fully invested. For example, when the portfolio manager and/or investment personnel believe that market conditions are unfavorable for investing, or when they are otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. In other words, cash or similar investments generally are a residual – they represent the assets that remain after a Fund has committed available assets to desirable investment opportunities. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.

In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment objective. As a result, the Fund may not achieve its investment objective.

Common Stock

Each of the Funds may invest substantially all of its assets in common stocks. The portfolio manager and/or investment personnel generally take a “bottom up” approach to selecting companies in which to invest. This means that they seek to identify individual companies with earnings growth potential that may not be recognized by the market at large. Securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. There are no limitations on the countries in which the Funds may invest, and the Funds may at times have significant exposure to emerging markets. The portfolio manager and/or investment personnel may sell a holding if, among other things, the security reaches the portfolio manager’s and/or investment personnel’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if the portfolio manager and/or investment personnel find a better investment opportunity. The portfolio manager and/or investment personnel may also sell a Fund holding to meet redemptions.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures, and options. Each Fund intends to enter into financial transactions with counterparties that Janus believes to be creditworthy at the time of the transaction. There is always the risk that Janus’ analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Emerging Markets

Each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International

24

Emerging Markets Index^sm. A summary of each Fund’s investments by country is contained in the Funds’ shareholder reports and in the Funds’ Form N-Q reports, which are filed with the Securities and Exchange Commission.

Illiquid Investments

Although the Funds intend to invest in liquid securities, each Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold to the U.S. public because of Securities and Exchange Commission regulations (these are known as “restricted securities”). Under procedures adopted by the Funds’ Trustees, certain restricted securities that are determined to be liquid will not be counted toward this 15% limit.

Portfolio Turnover

In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund, the nature of a Fund’s investments, and the investment style of the portfolio manager and/or investment personnel. Changes are normally made in a Fund’s portfolio whenever the portfolio manager and/or investment personnel believe such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions.

Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance.

Short Sales

The Funds may engage in short sales. No more than 10% of a Fund’s net assets may be invested in short positions (through short sales of stocks, structured products, futures, swaps, and uncovered written calls). The Funds may engage in short sales “against the box” and options for hedging purposes that are not subject to this 10% limit. A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs at a time that other short sellers of the same security also want to close out their positions, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a Fund that does not engage in short sales and may negatively affect the Fund’s performance.

A Fund may also enter into short positions through derivative instruments such as options contracts, futures contracts, and swap agreements which may expose the Fund to similar risks. To the extent that the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Due to certain foreign countries’ restrictions, a Fund will not be able to engage in short sales in certain foreign countries where it may maintain long positions. As a result, a Fund’s ability to fully implement a short selling strategy that could otherwise help the Fund pursue its investment goals may be limited. There can be no assurance that the implementation of a short sale strategy will be successful.

25

Special Situations

The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of a Fund’s portfolio manager and/or investment personnel, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.

Swap Agreements

The Funds may utilize swap agreements as a means to gain exposure to certain common stocks and/or to “hedge” or protect their portfolios from adverse movements in securities prices, the rate of inflation, or interest rates. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, equity, interest rate, and total return swaps are described in the “Glossary of Investment Terms” included as Appendix D.

Other Types of Investments

Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies, as described in the “Glossary of Investment Terms” included as Appendix D. These securities and strategies are not principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:

•  debt securities (such as bonds, notes, and debentures)

•  exchange-traded funds

•  indexed/structured securities (such as mortgage- and asset-backed securities)

•  various derivative transactions (which could comprise a significant percentage of a fund’s portfolio) including, but not limited to, options, futures, forwards, swap agreements (such as equity, interest rate, inflation index, credit default, and total return swaps), participatory notes, structured notes, and other types of derivatives individually or in combination for hedging purposes or for nonhedging purposes such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses; such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs

•  securities purchased on a when-issued, delayed delivery, or forward commitment basis

Fundamental Investment Restrictions

Each Fund has certain additional fundamental investment restrictions that can only be changed with shareholder approval. The Funds have identical fundamental investment restrictions and these restrictions are shown in Appendix B.

Additional Risks of the Funds

The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The following information is designed to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security.

Emerging Markets Risk.  Each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the MSCI

26

Emerging Markets Index^sm. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The price of investments in emerging markets can experience sudden and sharp price swings. The securities markets of many of the countries in which a Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.

Foreign Exposure Risks.  Each Fund will invest in foreign debt and equity securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Investments in foreign securities, including securities of foreign and emerging markets governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:

•  Currency Risk.  As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.

•  Political and Economic Risk.  Foreign investments may be subject to heightened political and economic risks, particularly in emerging markets which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominately based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

•  Regulatory Risk.  There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.

•  Foreign Market Risk.  Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.

•  Geographic Investment Risk.  To the extent that a Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, or regulatory events in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.

•  Transaction Costs.  Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Industry Risk.  Industry risk is the possibility that a group of related securities will decline in price due to industry-specific developments. Companies in the same or similar industries may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry increase that Fund’s exposure to industry risk.

27

Management Risk.  The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies employed for the Funds may fail to produce the intended results. A Fund may underperform its benchmark index or other mutual funds with similar investment objectives.

Because the Funds may invest substantially all of their assets in common stocks, the main risk is the risk that the value of the stocks they hold might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, a Fund’s share price may also decrease.

The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return swaps), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that a portfolio manager’s and/or investment personnel’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk.

A Fund’s performance may also be significantly affected, positively or negatively, by a portfolio manager’s and/or investment personnel’s use of certain types of investments, such as foreign (non-U.S.) securities, non-investment grade bonds (“junk bonds”), initial public offerings (“IPOs”), or securities of companies with relatively small market capitalizations. Note that a portfolio manager’s and/or investment personnel’s use of IPOs and other types of investments may have a magnified performance impact on a fund with a small asset base and the fund may not experience similar performance as its assets grow.

Market Risk.  The value of a Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s and/or investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money.

It is also important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in net asset value, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude the Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) in July 2010 which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity (or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

28

In addition, European markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels, and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal, and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and worldwide sellers of credit default swaps linked to that country’s creditworthiness. These trends have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of all European countries, which in turn may have a material adverse effect on a Fund’s investments in such countries, other countries that depend on European countries for significant amounts of trade or investment, or issuers with exposure to European debt.

Sovereign Debt Risk.  Each Fund may invest in U.S. and foreign government debt securities (“sovereign debt”). Investments in U.S. sovereign debt are considered low risk. However, investments in non-U.S. sovereign debt can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. A Fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the Fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.

Other Comparative Information about the Funds

Investment Adviser

Janus Capital Management LLC, 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund and will be the Combined Fund’s investment adviser after the Merger. Janus is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning each Fund’s investments. Janus also provides certain administration and other services and is responsible for other business affairs of each Fund.

Janus (together with its predecessors) has served as investment adviser to Janus mutual funds since 1970 and currently serves as investment adviser to all of the Janus funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.

Janus furnishes certain administration, compliance, and accounting services for the Funds and is reimbursed by the Funds for certain of its costs in providing those services. In addition, employees of Janus and/or its affiliates serve as officers of the Trust. Janus provides office space for the Funds. Some expenses related to compensation payable to the Funds’ Chief Compliance Officer and compliance staff are shared with the Janus funds. The Funds also pay for salaries, fees, and expenses of certain Janus employees and Fund officers, with respect to certain specified administration functions they perform on behalf of the Janus funds, including the Funds. The Funds pay these costs based on out-of-pocket expenses incurred by Janus, and these costs are separate and apart from management fees and other expenses paid in connection with the investment advisory services Janus provides to the Funds.

Management Expenses

Each Fund pays Janus a management fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, any other transfer agent and custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s management fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the management fee and other expenses that each Fund must pay.

The following table reflects each Fund’s contractual base management fee rate (expressed as an annual rate), as well as the actual management fee rate paid by each Fund to Janus (gross and net of fee waivers, if applicable).

Each Fund pays a management fee rate that may adjust up or down based on each Fund’s performance relative to the cumulative investment record of its benchmark index over the performance measurement period as reflected in the table below. The

29

third column shows the performance hurdle for outperformance or underperformance during the measurement period relative to each Fund’s respective benchmark index. Each Fund has the same performance hurdle of ±6.00%. The fourth column shows the performance adjusted management fee rate, which is equal to the Fund’s base fee rate plus or minus the Performance Adjustment over the period without any fee waivers. The fifth column shows the actual management fee rate, which is equal to the Fund’s base fee rate plus or minus the Performance Adjustment over the period and includes any applicable fee waiver. This fifth column shows the actual amount of the management fee rate paid by each Fund as of the fiscal year ended September 30, 2012.

As an example, if a Fund outperformed its benchmark index over the performance measurement period by 6.00%, the management fee would increase by 0.15% (assuming constant assets). Conversely, if a Fund underperformed its benchmark index over the performance measurement period by 6.00%, the management fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the performance hurdle rate may result in positive or negative incremental adjustments to the management fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the Funds’ SAI.

						Performance
			Performance			Adjusted		Actual
	Base Fee		Hurdle vs.			Management Fee		Management Fee
Fund Name	Rate (%)		Benchmark Index			Rate(1)(%)		Rate(1)(2)(%)
Global Research Fund		0.64		±6.00	%		0.74		0.74
Worldwide Fund		0.60		±6.00	%		0.59		0.59
Combined Fund (post-Merger)		0.60		±6.00	%		0.70		0.59	(3)

(1) Information is shown for the fiscal year ended September 30, 2012.

(2) Janus has agreed to waive each Fund’s total annual fund operating expenses (excluding any Performance Adjustment to the management fee rate, the distribution and shareholder servicing fees, administrative services fees payable pursuant to the Transfer Agency Agreement, brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) to the extent such annual fund operating expenses exceed 1.07% for each Fund (after reduction of any applicable share class level expenses), until at least February 1, 2014. Application of the expense waivers and their effect on annual fund operating expenses is reflected, when applicable, under Total Annual Fund Operating Expenses After Fee Waiver in the table in the “Comparison of Fees and Expenses” section of this Proxy Statement/Prospectus, with additional information included under “Expense Limitations.” The waivers and any applicable Performance Adjustments are not reflected in the base fee rates shown.

(3) Assumes consummation of the Merger on September 30, 2012. Reflects reduction in management fee rate based on Janus’ agreement to waive management fees for a three-year period as described in this Proxy Statement/Prospectus.

For each Fund, the management fee rate is determined by taking the appropriate base fee rate (shown in the previous table) and applying a Performance Adjustment (described in further detail below). The Performance Adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index as shown below:

Fund Name	Benchmark Index
Global Research Fund	MSCI World Growth Index
Worldwide Fund	MSCI World Indexsm
Combined Fund (post-Merger)	MSCI World Indexsm

The calculation of the performance adjustment applies as follows:

Management Fee = Base Fee Rate +/– Performance Adjustment

The management fee rate paid to Janus by each Fund consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the management fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period is a rolling 36-month period.

For purposes of the performance fee calculation assuming consummation of the Merger on September 30, 2012, the management fee rate for the Combined Fund is calculated by applying the annual base management fee rate of 0.60% to the Combined Fund’s average daily net assets during the previous month (which would be the assets of Global Research Fund only), plus or minus the Performance Adjustment which is calculated on the prior 36 months performance history of Global Research Fund relative to the MSCI World Index^sm. Beginning one month after the date of the Merger, the assets of Worldwide Fund are added to the Combined Fund to calculate the management fee.

30

For purposes of determining any waiver of the Performance Adjustment to the management fee, assuming consummation of the Merger on September 30, 2012, the management fee rate for the Combined Fund is calculated by applying the annual base management fee rate of 0.60% to the Combined Fund’s average daily net assets during the previous month (which would be the assets of Worldwide Fund only), plus or minus the Performance Adjustment which is calculated on the prior 36 months performance history of Worldwide Fund relative to the MSCI World Index^sm. Beginning one month after the date of the Merger, the assets of Global Research Fund are added in for purposes of calculating a performance fee that would have applied if Worldwide Fund were the performance and accounting survivor rather than Global Research Fund. Any waiver is the difference in the actual Performance Adjustment and what the Performance Adjustment would have been had Worldwide Fund been the accounting and performance survivor after the Merger.

A hypothetical example of how these calculations are applied is included as Appendix E.

For purposes of calculating the performance fee, no Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus’ fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus’ fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The management fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus would reimburse the applicable Fund.

The application of an expense limit, if any, as well as the three-year waiver by Janus discussed in this Proxy Statement/Prospectus, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus. For the first three years after the Merger, Janus has agreed to waive the Performance Adjustment to the Base Fee to a level that reflects the lower of the Performance Adjustment with Global Research Fund as the accounting and performance survivor or the Performance Adjustment assuming Worldwide Fund had been the performance and accounting survivor, as explained in this Proxy Statement/Prospectus. If the application of this waiver results in the Combined Fund outperforming the MSCI World Index^sm to a greater extent than it would have without the waiver, as a shareholder of the Combined Fund, you could end up paying more in management fees once the waiver is removed.

The investment performance of the Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After Janus determines whether the Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares against the cumulative investment record of that Fund’s benchmark index, Janus applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

A discussion regarding the basis for the Trustees’ approval of the Funds’ current investment advisory agreements is included in the Funds’ semiannual report to shareholders dated March 31, 2012.

Investment Personnel

Global Research Fund

The Research Team (Janus’ equity research analysts overseen by the Portfolio Oversight Team led by James P. Goff) selects investments for Global Research Fund and has done so since inception. If the Merger is approved, the Research Team will select investments for the Combined Fund effective with the Merger, replacing Mr. Maris.

31

James P. Goff, CFA, is Janus’ Director of Equity Research and Executive Vice President of the Fund. Mr. Goff is primarily responsible for the day-to-day operations of the Fund. He leads the Portfolio Oversight Team that reviews the Fund’s risks, overall structure, and guidelines. Mr. Goff joined Janus in 1988. He holds a Bachelor of Arts degree (magna cum laude) in Economics from Yale University. Mr. Goff holds the Chartered Financial Analyst designation.

Worldwide Fund

George P. Maris, CFA, is Executive Vice President and Portfolio Manager of Worldwide Fund, which he has managed since March 2011. Mr. Maris joined Janus in March 2011. Prior to joining Janus, Mr. Maris was a portfolio manager at Northern Trust from 2008 to March 2011, and a portfolio manager with Columbia Management Group from 2004 to 2008. Mr. Maris holds a Bachelor’s degree in Economics from Swarthmore College, a Juris Doctorate from the University of Illinois College of Law, and a Master of Business Administration degree from the University of Chicago. He holds the Chartered Financial Analyst designation.

Worldwide Fund’s and Global Research Fund’s combined SAI, dated January 27, 2012, which is incorporated by reference herein, provides information about Mr. Goff’s and Mr. Maris’ compensation structure and other accounts managed, as well as the range of their individual ownership of securities of the specific Fund(s) they manage and the aggregate range of their individual ownership in all mutual funds advised by Janus.

Conflicts of Interest

Janus manages many funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, Janus is the adviser to the Janus “funds of funds,” which are funds that invest primarily in other mutual funds managed by Janus. Because Janus is the adviser to the Janus “funds of funds” and the Funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus “fund of funds” among such Funds. To the extent that a Fund is an underlying fund in a Janus “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so. Such transactions could accelerate the realization of taxable income if sales of securities resulted in gains and could also increase a fund’s transaction costs. Large redemptions by a Janus “fund of funds” may cause a fund’s expense ratio to increase due to a resulting smaller asset base. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI, which is incorporated by reference herein.

Charter Documents

The following is a summary of certain provisions of the Trust Instrument that each Fund is governed by and is qualified in its entirety by reference to the Trust Instrument.

Voting.  As a shareholder, you are entitled to one vote for each whole dollar and a proportionate fractional vote for each fractional dollar of NAV of the Fund that you own. Generally, all funds and classes vote together as a single group, except where a separate vote of one or more funds or classes is required by law or where the interests of one or more funds or classes are affected differently from other funds or classes. Shares of all series of the Trust have noncumulative voting rights, which means that the holders of more than 50% of the value of shares of all series of the Trust voting for the election of Trustees can elect 100% of the Trustees if they choose to do so. In such event, the holders of the remaining value of shares will not be able to elect any Trustees.

All shares of a Fund participate equally in dividends and other distributions by the shares of the same class of that Fund, and in residual assets of that class of that Fund in the event of liquidation. Shares of each Fund have no preemptive, conversion, or appraisal rights. Shares of each Fund may be transferred by endorsement or stock power as is customary, but a Fund is not bound to recognize any transfer until it is recorded on its books. The Funds have the right to redeem, at the then current NAV, the shares of any shareholder whose account does not meet certain minimum requirements as described in the Funds’ prospectuses and also included in Appendix C.

Shareholder Meetings.  The Trust is not required, and does not intend, to hold annual shareholder meetings unless otherwise required by the Trust Instrument, the 1940 Act or in compliance with any regulatory order. Special meetings may be called for a specific fund or for the Trust for purposes such as election of Trustees, when required by the Trust Instrument or to comply with the 1940 Act or a regulatory order. Under the Trust Instrument, special meetings of shareholders of the Trust or of any fund shall be called upon written request of shareholders holding not less than 10% of the shares then outstanding.

Shareholder Liability.  Under Massachusetts law, shareholders of a Massachusetts business trust could, under certain circumstances, be held liable for the obligations of their Fund. However, the Trust Instrument disclaims shareholder liability for acts or obligations of the Funds and requires that notice of this disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Funds or the Trustees. The Trust Instrument also provides for indemnification from the assets of the Funds for all losses and expenses of any Fund shareholder held liable for the obligations of their Fund. The Trustees intend to conduct the operations of the Funds to avoid, to the extent possible, liability of shareholders for liabilities of their Fund.

Trustee Liability.  A Trustee shall be liable for such Trustee’s own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee, and shall not be liable for errors of judgment or mistakes of fact or law. All persons extending credit to, contracting with or having any claim against the Trust shall look only to the assets of the Fund with which such person dealt for payment under such credit, contract, or claim.

33

Liquidation or Dissolution.  In the event of the liquidation or dissolution of the Trust, shareholders of the funds are entitled to receive, when and as declared by the Trustees, the excess of the assets belonging to their fund, or in the case of a class, belonging to that fund and allocable to that class, over the liabilities belonging to that fund or class. The assets shall be distributed to shareholders in proportion to the relative NAV of the shares of that fund or class held by them and recorded on the books of the Trust. The liquidation of any particular fund or class thereof may be authorized at any time by vote of a majority of the Trustees then in office. Shareholders will receive prior notice of any liquidation effecting their fund or class.

ADDITIONAL INFORMATION

Quorum and Voting

Shareholders of Global Research Fund will vote together at the Meeting. Each holder of a whole or fractional share shall be entitled to one vote for each whole dollar value or a proportionate fractional vote for each fractional dollar value of NAV held in such shareholder’s name. If you are not the owner of record, but your shares are instead held for your benefit by a financial intermediary such as a retirement plan service provider, broker-dealer, bank trust department, insurance company, or other financial intermediary, that financial intermediary may request that you instruct it how to vote the shares you beneficially own. Your financial intermediary will provide you with additional information.

Thirty percent of the outstanding shares entitled to vote at the Meeting shall be a quorum for the transaction of business at the Meeting. Any lesser number is sufficient for adjournments. In the event that the necessary quorum to transact business or the vote required to approve the Merger is not obtained at the Meeting, the persons named as proxies may propose one or more adjournments of the Meeting, in accordance with applicable law, to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of the holders of a majority of the shares of Global Research Fund, present in person or by proxy at the Meeting. The persons named as proxies will vote the proxies, in accordance with applicable law, in favor of adjournment if they determine additional solicitation is warranted and in the interests of Global Research Fund’s shareholders.

“Broker non-votes” are shares held by a broker or nominee for which an executed proxy is received by the Trust, but are not voted because instructions have not been received from beneficial owners or persons entitled to vote and the broker or nominee does not have discretionary voting power. Abstentions and broker non-votes are counted as shares eligible to vote at the Meeting in determining whether a quorum is present, but do not represent votes cast in favor of an adjournment, postponement, or the Merger. Accordingly, assuming the presence of a quorum, abstentions and broker non-votes will have the same effect as a vote against the Merger.

Approval of the Merger will require the affirmative vote of a “majority of the outstanding voting securities” of Global Research Fund within the meaning of the 1940 Act. This means the lesser of (1) 67% or more of the shares present at the Meeting if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (2) more than 50% of the outstanding shares.

Share Ownership

As of November 30, 2012, the officers and Trustees as a group owned approximately 1.1% of Class D Shares of Global Research Fund, 4.9% of Class I Shares of Global Research Fund, and less than 1% of the outstanding shares of any other class of Global Research Fund. In addition, the officers and Trustees as a group owned less than 1% of the outstanding shares of any class of Worldwide Fund. As of November 30, 2012, the percentage ownership of any person or entity owning 5% or more of the outstanding shares of any class of the Funds is listed below. In addition, the percentage ownership of any person or entity owning 25% or more of the outstanding shares of any class of the Funds is listed below. Any person who owns, directly or through one or more controlled companies, more than 25% of the voting securities of a company is presumed to “control” such company. Accordingly, to the extent that a person is identified as the beneficial owner of more than 25% of a Fund, or is identified as the record owner of more than 25% of a Fund and has voting and/or investment powers, that person may be presumed to control such Fund. A controlling person’s vote could have a more significant effect on matters presented to shareholders for approval than the vote of other Fund shareholders.

To the best knowledge of the Trust, as of November 30, 2012, no other person or entity owned beneficially more than 5% of the outstanding shares of any class of the Funds, except as shown. Additionally, to the best knowledge of the Trust, no other person or entity beneficially owned 25% or more of the outstanding shares of any class of the Funds, except as shown. To the best knowledge of the Trust, entities shown as owning more than 25% of the outstanding shares of a class of a Fund are not the beneficial owners of such shares, unless otherwise indicated.

Solicitation of Proxies

Janus and Global Research Fund will each pay half of the fees and expenses related to the Merger, including the costs associated with the drafting, printing, and mailing of this Proxy Statement/Prospectus, the solicitation of proxies, and the Meeting. In addition to solicitation of proxies by mail, certain officers and representatives of the Trust, certain officers and employees of Janus or its affiliates, certain financial services firms and their representatives, without extra compensation, or a solicitor, may solicit proxies personally, by telephone, U.S. Mail, facsimile, verbal, internet, or email communications.

Janus has engaged Computershare, a professional proxy solicitation firm, to assist in the solicitation of proxies, at an estimated cost of $300,000 plus any out-of-pocket expenses. Such expenses will be split between Janus and Global Research Fund. Among other things, Computershare will be (i) required to maintain the confidentiality of all shareholder information; (ii) prohibited from selling or otherwise disclosing shareholder information to any third party; and (iii) required to comply with applicable telemarketing laws.

Brokers, banks, and other fiduciaries may be required to forward soliciting material to their principals on behalf of Global Research Fund and to obtain authorization for the execution of proxies. To the extent Janus or Global Research Fund would have directly borne the expenses for those services, Janus and Global Research Fund, equally sharing the costs, will reimburse these intermediaries for their expenses.

As the Meeting date approaches, certain shareholders whose votes have not been received, may receive telephone calls from a representative of Computershare. Authorization to permit Computershare to execute proxies may be obtained by telephonic or electronically transmitted instructions from shareholders of Global Research Fund. Proxies that are obtained telephonically will be recorded in accordance with the procedures described below. Global Research Fund believes that these procedures are reasonably designed to ensure that both the identity of the shareholder casting the vote and the voting instructions of the shareholder are accurately determined.

In all cases where a telephonic proxy is solicited, the Computershare representative is required to ask for each shareholder’s full name, address, title (if the shareholder is authorized to act on behalf of an entity, such as a corporation), and to confirm that the shareholder has received the Proxy Statement/Prospectus and proxy card(s) in the mail. If the information solicited agrees with the information provided to Computershare, then the Computershare representative has the responsibility to explain the process, and ask for the shareholder’s instructions on the proposal. Although the Computershare representative is permitted to answer questions about the process, he or she is not permitted to recommend to the shareholder how to vote. The Computershare representative may read any recommendation set forth in this Proxy Statement/Prospectus. The Computershare representative will record the shareholder’s instructions. Within 72 hours, the shareholder will be sent a confirmation of his or her vote asking the shareholder to call 1-866-492-0863 immediately if his or her instructions are not accurately reflected in the confirmation.

Telephone Touch-Tone Voting.  Shareholders may provide their voting instructions through telephone touch-tone voting by following the instructions on the enclosed proxy card(s). Shareholders will have an opportunity to review their voting instructions and make any necessary changes before submitting their voting instructions and terminating their telephone call.

Internet Voting.  Shareholders may provide their voting instructions through Internet voting by following the instructions on the enclosed proxy card(s). Shareholders who vote via the Internet, in addition to confirming their voting instructions prior to submission and terminating their Internet link, will, upon request, receive an e-mail confirming their voting instructions. If a shareholder wishes to participate in the Meeting but does not wish to give a proxy by telephone or via the Internet, the shareholder may still submit the proxy card(s) originally sent with the Proxy Statement/Prospectus in the postage paid envelope provided, or

39

attend the Meeting in person. Shareholders requiring additional information regarding the proxy or replacement proxy card(s), may contact Computershare at 1-866-492-0863. Any proxy given by a shareholder is revocable until voted at the Meeting.

Revoking a Proxy.  Any shareholder submitting a proxy has the power to revoke it at any time before it is exercised by submitting to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206, a written notice of revocation or a subsequently executed proxy or by attending the Meeting and voting in person. All properly executed and unrevoked proxies received in time for the Meeting will be voted as specified in the proxy, or, if no specification is made, will be voted FOR the Merger described in this Proxy Statement/Prospectus.

Shares Held by Accounts of Insurance Companies.  Shares of Global Research Fund may be held by certain separate accounts of insurance companies to fund benefits payable under certain variable annuity contracts and variable life insurance policies. Your insurance company may request that you provide it with voting instructions for your beneficially held shares of any such separate account. If you do not provide voting instructions to your insurance company, it may vote all of the shares held in that separate account in the same proportions as the voting actually received from other variable contract holders for that separate account.

Shareholder Proposals for Subsequent Meetings

Global Research Fund is not required, and does not intend, to hold annual shareholder meetings. Shareholder meetings may be called from time to time as described in the Trust Instrument and the Trust’s Amended and Restated Bylaws. Under the proxy rules of the SEC, shareholder proposals that meet certain conditions may be included in Global Research Fund’s proxy statement for a particular meeting. Those rules currently require that for future meetings, the shareholder must be a record or beneficial owner of Global Research Fund shares either (i) with a value of at least $2,000 or (ii) in an amount representing at least 1% of Global Research Fund’s securities to be voted, at the time the proposal is submitted and for one year prior thereto, and must continue to own such shares through the date on which the meeting is held. Another requirement relates to the timely receipt by Global Research Fund of any such proposal. Under those rules, a proposal must have been submitted within a reasonable time before Global Research Fund began to print and mail this Proxy Statement/Prospectus in order to be included in this Proxy Statement/Prospectus. A proposal submitted for inclusion in Global Research Fund’s proxy material for the next special meeting after the meeting to which this Proxy Statement/Prospectus relates must be received by Global Research Fund within a reasonable time before the Fund begins to print and mail the proxy materials for that meeting.

Shareholders wishing to submit a proposal for inclusion in a proxy statement subsequent to the Meeting, if any, should send their written proposal to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206 within a reasonable time before Global Research Fund begins to print and mail the proxy materials for that meeting. Notice of shareholder proposals to be presented at the Meeting must have been received within a reasonable time before the Fund began to mail this Proxy Statement/Prospectus. The timely submission of a proposal does not guarantee its inclusion in the proxy materials.

Other Matters to Come Before the Meeting

The Trustees are not aware of any matter that will be presented for action at the Meeting other than the matter described in this Proxy Statement/Prospectus. Should any other matters requiring a vote of shareholders arise, the proxy in the accompanying form will confer upon the person or persons entitled to vote the shares represented by such proxy the discretionary authority to vote the shares as to any other matters in accordance with their best judgment in the interest of the Trust and/or Fund.

Copies of Fund Information

To avoid sending duplicate copies of materials to certain households, the Fund may mail only one copy of each report or this Proxy Statement/Prospectus to shareholders having the same last name and address on the Fund’s records. The consolidation of these mailings benefits the Fund through reduced mailing expenses. With respect to Class D Shares, if a shareholder wants to receive multiple copies of these materials or to receive only one copy in the future, the shareholder should contact the Fund’s transfer agent, Janus Services, at 1-800-525-3713, or notify the Fund’s transfer agent in writing at P.O. Box 55932, Boston, MA 02205-5932.

40

Please complete, sign, and return the enclosed proxy card(s) or vote by telephone or internet promptly. No postage is required if you mail your proxy card(s) in the United States.

By order of the Board of Trustees,

Robin C. Beery
Chief Executive Officer and President of
Janus Investment Fund

APPENDIX A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”) is made as of this [          ] day of [          , 2012], by and between Janus Investment Fund, a Massachusetts business trust (the “Trust”), on behalf of Janus Global Research Fund, a series of the Trust (the “Predecessor Fund”), and Janus Worldwide Fund, a series of the Trust (the “Successor Fund”).

All references in this Agreement to action taken by the Predecessor Fund or the Successor Fund shall be deemed to refer to action taken by the Trust on behalf of the respective portfolio series.

This Agreement is intended to be and is adopted as a plan of reorganization and liquidation within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”). The reorganization (the “Reorganization”) will consist of the transfer by the Predecessor Fund of all or substantially all of its assets to the Successor Fund, in exchange solely for Class A, Class C, Class D, Class I, Class S and Class T voting shares of beneficial interest in the Successor Fund (the “Successor Fund Shares”) having an aggregate net asset value equal to the aggregate net asset value of the same class of shares of the Predecessor Fund, the assumption by the Successor Fund of all the liabilities of the Predecessor Fund, and the distribution of the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares to the shareholders of the Predecessor Fund in complete liquidation of the Predecessor Fund as provided herein, all upon the terms and conditions hereinafter set forth in this Agreement.

WHEREAS, the Board of Trustees of the Trust has determined that it is in the best interest of each of the Predecessor Fund and the Successor Fund that the assets of the Predecessor Fund be acquired by the Successor Fund pursuant to this Agreement and in accordance with the applicable statutes of the Commonwealth of Massachusetts, and that the interests of existing shareholders will not be diluted as a result of this transaction;

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

1.   PLAN OF REORGANIZATION

1.1  Subject to the terms and conditions herein set forth, the Trust shall (i) transfer all or substantially all of the assets of the Predecessor Fund, as set forth in paragraph 1.2, to the Successor Fund, (ii) the Trust shall cause the Successor Fund to deliver to the Trust full and fractional Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares having an aggregate net asset value equal to the value of the aggregate net assets of the same class of shares of the Predecessor Fund as of the close of regular session trading on the New York Stock Exchange on the Closing Date, as set forth in paragraph 2.1 (the “Closing Date”) and (iii) the Trust shall cause the Successor Fund to assume all liabilities of the Predecessor Fund, as set forth in paragraph 1.2. Such transactions shall take place at the closing provided for in paragraph 2.1 (the “Closing”).

1.2  The assets of the Predecessor Fund to be acquired by the Successor Fund shall consist of all property, including, without limitation, all cash, securities, commodities and futures interests, and dividends or interest receivable which are owned by the Predecessor Fund and any deferred or prepaid expenses shown as an asset on the books of the Predecessor Fund on the Closing Date. The Successor Fund will assume all of the liabilities, expenses, costs, charges and reserves of the Predecessor Fund of any kind, whether absolute, accrued, contingent or otherwise in existence on the Closing Date.

1.3  The Predecessor Fund will distribute pro rata to its shareholders of record of the applicable classes, determined as of immediately after the close of business on the Closing Date (the “Current Shareholders”), the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares received by the Trust pursuant to paragraph 1.1. Such distribution and liquidation will be accomplished by the transfer of the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares then credited to the accounts of the Predecessor Fund on the books of the Successor Fund to open accounts on the share records of the Successor Fund in the names of the Current Shareholders and representing the respective pro rata number of the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares due to such shareholders. All issued and outstanding shares of the Predecessor Fund will simultaneously be canceled on the books of the Trust. The Successor Fund shall not issue certificates representing the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares in connection with such exchange. Ownership of Class A, Class C, Class D, Class I, Class R (to which no assets are exchanged related to the Reorganization), Class S and Class T

A-1

Successor Fund Shares will be shown on the books of the Trust’s transfer agent. As soon as practicable after the Closing, the Trust shall take all steps necessary to effect a complete liquidation of the Predecessor Fund.

2.   CLOSING AND CLOSING DATE

2.1  The Closing Date shall be [          ] [          ], [2013], or such other date as the parties may agree to in writing. All acts taking place at the Closing shall be deemed to take place simultaneously as of immediately after the close of business on the Closing Date unless otherwise agreed to by the parties. The close of business on the Closing Date shall be as of 4:00 p.m. New York Time. The Closing shall be held at the offices of Janus Capital Management LLC (“JCM”), 151 Detroit Street, Denver, Colorado 80206-4805, or at such other time and/or place as the parties may agree.

2.2  The Trust shall cause Janus Services LLC (the “Transfer Agent”), transfer agent of the Predecessor Fund, to deliver at the Closing a certificate of an authorized officer stating that its records contain the names and addresses of the Current Shareholders and the number, class, and percentage ownership of outstanding shares of the Predecessor Fund owned by each such shareholder immediately prior to the Closing. The Successor Fund shall issue and deliver a confirmation evidencing the Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares to be credited on the Closing Date to the Secretary of the Trust or provide evidence satisfactory to the Trust that such Class A, Class C, Class D, Class I, Class S and Class T Successor Fund Shares have been credited to the accounts of the Predecessor Fund on the books of the Successor Fund. At the Closing, each party shall deliver to the other such bills of sales, checks, assignments, share certificates, if any, receipts or other documents as such other party or its counsel may reasonably request.

APPENDIX B

INVESTMENT POLICIES AND RESTRICTIONS

Fundamental Investment Policies and Restrictions:

The Funds are subject to certain fundamental policies and restrictions that may not be changed without shareholder approval. Shareholder approval means approval by the lesser of: (i) more than 50% of the outstanding voting securities of the Trust (or a particular Fund or particular class of shares if a matter affects just that Fund or that class of shares) or (ii) 67% or more of the voting securities present at a meeting if the holders of more than 50% of the outstanding voting securities of the Trust (or a particular Fund or class of shares) are present or represented by proxy. The following policies are fundamental policies of the Funds.

(1) With respect to 75% of its total assets, the Funds may not purchase securities of an issuer (other than the U.S. Government, its agencies, instrumentalities or authorities, or repurchase agreements collateralized by U.S. Government securities, and securities of other investment companies) if: (a) such purchase would, at the time, cause more than 5% of the Fund’s total assets taken at market value to be invested in the securities of such issuer or (b) such purchase would, at the time, result in more than 10% of the outstanding voting securities of such issuer being held by the Fund.

Each Fund may not:

(2) Invest 25% or more of the value of its total assets in any particular industry (other than U.S. Government securities).

(3) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this limitation shall not prevent a Fund from purchasing or selling foreign currencies, options, futures, swaps, forward contracts, or other derivative instruments, or from investing in securities or other instruments backed by physical commodities).

(4) Lend any security or make any other loan if, as a result, more than one-third of a Fund’s total assets would be lent to other parties (but this limitation does not apply to investments in repurchase agreements, commercial paper, debt securities, or loans, including assignments and participation interests).

(5) Act as an underwriter of securities issued by others, except to the extent that a Fund may be deemed an underwriter in connection with the disposition of its portfolio securities.

(6) Borrow money except that a Fund may borrow money for temporary or emergency purposes (not for leveraging or investment). Borrowings from banks will not, in any event, exceed one-third of the value of a Fund’s total assets (including the amount borrowed). This policy shall not prohibit short sales transactions or futures, options, swaps, or forward transactions. The Funds may not issue “senior securities” in contravention of the 1940 Act.

(7) Invest directly in real estate or interests in real estate; however, a Fund may own debt or equity securities issued by companies engaged in those businesses.

As a fundamental policy, a Fund may, notwithstanding any other investment policy or limitation (whether or not fundamental), invest all of its assets in the securities of a single open-end management investment company with substantially the same fundamental investment objectives, policies, and limitations as such Fund.

The Board of Trustees (“Trustees”) has adopted additional investment restrictions for the Funds. These restrictions are operating policies of the Funds and may be changed by the Trustees without shareholder approval. The additional restrictions adopted by the Trustees to date include the following:

(1) If a Fund is an approved underlying fund in a Janus fund of funds, the Fund may not acquire the securities of other investment companies or registered unit investment trusts in excess of the limits of Section 12(d)(1) of the 1940 Act in reliance on subparagraph (F) or subparagraph (G) of Section 12(d)(1).

(2) The Funds may sell securities short if they own or have the right to obtain securities equivalent in kind and amount to the securities sold short without the payment of any additional consideration therefor (“short sales against the box”). In addition, each Fund may engage in short sales other than against the box, which involve selling a security that a Fund borrows and does not own. The Trustees may impose limits on a Fund’s investments in short sales, as described in this Proxy Statement/Prospectus. Transactions in futures, options, swaps, and forward contracts not involving short sales are not deemed to constitute selling securities short.

B-1

(3) The Funds do not intend to purchase securities on margin, except that the Funds may obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments and other deposits in connection with transactions involving short sales, futures, options, swaps, forward contracts, and other permitted investment techniques shall not be deemed to constitute purchasing securities on margin.

(4) A Fund may not mortgage or pledge any securities owned or held by such Fund in amounts that exceed, in the aggregate, 15% of that Fund’s net asset value (“NAV”), provided that this limitation does not apply to: reverse repurchase agreements; deposits of assets to margin; guarantee positions in futures, options, swaps, or forward contracts; or the segregation of assets in connection with such contracts.

(5) The Funds do not currently intend to purchase any security or enter into a repurchase agreement if, as a result, more than 15% of their respective net assets would be invested in repurchase agreements not entitling the holder to payment of principal and interest within seven days and in securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market. The Trustees, or the Funds’ investment adviser acting pursuant to authority delegated by the Trustees, may determine that a readily available market exists for: securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933, as amended (“Rule 144A Securities”), or any successor to such rule; Section 4(2) commercial paper; and municipal lease obligations. Accordingly, such securities may not be subject to the foregoing limitation.

(6) The Funds may not invest in companies for the purpose of exercising control of management.

Under the terms of an exemptive order received from the SEC, each Fund may borrow money from or lend money to other funds that permit such transactions and for which Janus or one of its affiliates serves as investment adviser. All such borrowing and lending will be subject to the above limits and to the limits and other conditions in such exemptive order. A Fund will borrow money through the program only when the costs are equal to or lower than the cost of bank loans. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. A Fund will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). A Fund may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending Fund could result in a lost investment opportunity or additional borrowing costs.

For the purposes of these investment restrictions, the identification of the issuer of a municipal obligation depends on the terms and conditions of the security. When assets and revenues of a political subdivision are separate from those of the government that created the subdivision and the security is backed only by the assets and revenues of the subdivision, the subdivision is deemed to be the sole issuer. Similarly, in the case of an industrial development bond, if the bond is backed only by assets and revenues of a nongovernmental user, then the nongovernmental user would be deemed to be the sole issuer. If, however, in either case, the creating government or some other entity guarantees the security, the guarantee would be considered a separate security that would be treated as an issue of the guaranteeing entity.

For purposes of each Fund’s policies on investing in particular industries, as of the date of the Funds’ currently effective SAI, each Fund relies primarily on industry or industry group classifications as published by Bloomberg L.P. To the extent that the Bloomberg L.P. classifications are so broad that the primary economic characteristics in a single class are materially different, a Fund may further classify issuers in accordance with industry classifications as published by the SEC or relevant SEC staff interpretations. The Funds intend to change industry or industry group classifications with respect to equity investments to Global Industry Classification Standard (“GICS”), but would continue to use Bloomberg L.P. for fixed-income investments. The Funds may change any source used for determining industry classifications without prior shareholder notice or approval.

APPENDIX C

ADDITIONAL INFORMATION ABOUT WORLDWIDE FUND

The Fund offers multiple classes of shares in order to meet the needs of various types of investors.

Class A Shares and Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares may be offered without an initial sales charge through certain retirement platforms and through certain financial intermediary platforms, including but not limited to, fee-based broker-dealers or financial advisors, primarily on their wrap account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the wrap account. Class A Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. Class C Shares pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class A Shares and Class C Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to shareholders.

Class D Shares are available only to investors who hold accounts directly with the Janus funds, and to immediate family members or members of the same household of an eligible individual investor. Under certain limited circumstances, shareholders of other Janus share classes who no longer wish to hold shares through an intermediary may be eligible to purchase Class D Shares.

Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with Janus or its affiliates to offer the shares on their supermarket platforms. Class S Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of their clients.

Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to shareholders. Class I Shares are also available to certain direct institutional investors including, but not limited to, corporations, certain retirement plans, public plans and foundations/endowments.

Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms. Class R Shares pay up to 0.50% of net assets to financial intermediaries for the provision of distribution services and, to a certain extent, shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of the plan or plan participants.

Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with Janus or its affiliates to offer the shares on their supermarket platforms. Class T Shares pay up to 0.25% of net assets to financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to shareholders.

The shares are not offered directly to individual investors with the exception of Class D Shares, and in certain circumstances, Class I Shares. Consult with your financial intermediary representative for additional information on whether the shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem shares, contact your financial intermediary or refer to

C-1

your plan documents. For Class D Shares, contact a Janus representative at 1-800-525-3713, or for Class I Shares held directly with Janus, please contact a Janus representative at 1-800-333-1181.

With certain limited exceptions, the Fund is available only to U.S. citizens or residents, and employees of Janus or its affiliates.

PRICING OF FUND SHARES

The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the regular trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the NAV may be calculated earlier if trading on the NYSE is restricted, or as permitted by the SEC. Foreign securities held by the Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s shares.

The price you pay for purchases of shares is the public offering price, which is the NAV next determined after your request is received in good order by the Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of shares. In order to receive a day’s price, your order must be received in good order by the Fund or its agents by the close of the regular trading session of the NYSE.

Securities held by the Fund are generally valued at market value. Certain short-term instruments maturing within 60 days or less are valued at amortized cost, which approximates market value. If a market quotation for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security (except for short-term instruments maturing within 60 days or less) will be determined in good faith under policies and procedures established by and under the supervision of the Fund’s Trustees. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. While fair value pricing may be more commonly used with foreign equity securities, it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Fund may use systematic fair valuation models provided by independent pricing services to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE.

Due to the subjective nature of fair value pricing, the Fund’s value for a particular security may be different from the last quoted market price. Fair value pricing may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of the Fund’s portfolio securities and the reflection of such change in the Fund’s NAV, as further described in the “Excessive Trading” section of this Proxy Statement/Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the Fund’s valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of the Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Fund’s fair value pricing and excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.

The value of the securities of other open-end funds held by the Fund, if any, will be calculated using the NAV of such open-end funds, and the prospectuses for such open-end funds explain the circumstances under which they use fair value pricing and the effects of using fair value pricing.

All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other

C-2

requests to the Fund under the arrangements made between your financial intermediary or plan sponsor and its customers. The Fund is not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.

CHOOSING A SHARE CLASS

Class A Shares, Class C Shares, Class D Shares, Class S Shares, Class I Shares, Class R Shares, and Class T Shares are offered by this Proxy Statement/Prospectus. The Fund offers multiple classes of shares in order to meet the needs of various types of investors. For more information about these classes of shares and whether or not you are eligible to purchase these shares, please call 1-877-335-2687.

Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. When choosing a share class, you should consider:

•  how much you plan to invest;

•  how long you expect to own the shares;

•  the expenses paid by each class; and

•  for Class A Shares and Class C Shares, whether you qualify for any reduction or waiver of any sales charges.

DISTRIBUTION, SERVICING, AND ADMINISTRATIVE FEES

Distribution and Shareholder Servicing Plans

Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the 1940 Act for Class A Shares, Class S Shares, and Class R Shares (each a “Plan”) and Class C Shares (the “Class C Plan”), the Fund may pay

C-4

Janus Distributors LLC (“Janus Distributors”), the Trust’s distributor, a fee for the sale and distribution and/or shareholder servicing of the shares based on the average daily net assets of each, at the following annual rates:

Class	12b-1 Fee for the Fund
Class A Shares		0.25%
Class C Shares		1.00%	(1)
Class S Shares		0.25%
Class R Shares		0.50%

(1)  Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.

Under the terms of each Plan, the Trust is authorized to make payments to Janus Distributors for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Fund.

Janus Distributors is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although Janus Distributors may, pursuant to a written agreement between Janus Distributors and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.

Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. Janus Distributors is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.

Because 12b-1 fees are paid out of the Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.

Administrative Fees

Class A Shares, Class C Shares, and Class I Shares

Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of the shareholders of the Fund. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with Janus. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. Janus Services remits these administrative fees to intermediaries on behalf of the Funds. Janus Services is then reimbursed by the Funds for such payments. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from Janus Services on behalf of the Fund converts from a networking structure to an omnibus account structure, or otherwise experiences increased costs, fees borne by the shares may increase. The Fund’s Trustees have set limits on fees that the Fund may incur with respect to order processing for omnibus or networked accounts. Such limits are subject to change by the Trustees in the future. Janus Services also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.

Class S Shares, Class R Shares, and Class T Shares

Janus Services, the Trust’s transfer agent, receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares, Class R Shares, and Class T Shares of the Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Fund. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with Janus. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. Janus Services expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Fund. Janus Services or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Fund.

C-5

Class D Shares

The Fund pays an annual administrative services fee of 0.12% of net assets of Class D Shares. These administrative services fees are paid by Class D Shares of the Fund for shareholder services provided by Janus Services.

PAYMENTS TO FINANCIAL INTERMEDIARIES BY JANUS OR ITS AFFILIATES

From its own assets, Janus or its affiliates may pay selected brokerage firms or other financial intermediaries that sell Class A and Class C Shares of the Janus funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by Janus, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Janus and its affiliates consider a number of factors in making payments to financial intermediaries, including the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with Janus’ marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Currently, these payments are limited to the top 100 distributors (measured by sales or expected sales of shares of the Janus funds). Broker-dealer firms currently receiving or expected to receive these fees are listed in the Fund’s combined SAI, which is incorporated by reference herein.

In addition, for most share classes, Janus, Janus Distributors, or their affiliates may pay fees, from their own assets, to brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via NSCC or other means) in connection with investments in the Janus funds. These fees are in addition to any fees that may be paid by the Janus funds for these types of services or other services.

Janus or its affiliates may also share certain marketing expenses with intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Fund. Janus or its affiliates may make payments to participate in intermediary marketing support programs which may provide Janus or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus funds available to their customers.

The receipt of (or prospect of receiving) payments, reimbursements and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus funds’ shares over sales of another Janus funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach Janus to request that Janus make contributions to certain charitable organizations. In these cases, Janus’ contribution may result in the financial intermediary, or its salespersons, recommending Janus funds over other mutual funds (or non-mutual fund investments).

C-6

The payment arrangements described above will not change the price an investor pays for shares nor the amount that a Janus fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you.

PURCHASES

With the exception of Class D Shares and Class I Shares, purchases of shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Class I Shares may be purchased directly with the Fund in certain circumstances as described in the “Minimum Investment Requirements” section. Contact your financial intermediary, a Janus representative (1-800-333-1181) if you hold Class I Shares directly with Janus, or refer to your plan documents for information on how to invest in the Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, the Fund may permit an in-kind purchase of shares at the discretion of Janus. Your financial intermediary may charge you a separate or additional fee for processing purchases of shares. Only certain financial intermediaries are authorized to receive purchase orders on the Fund’s behalf. As discussed under “Payments to financial intermediaries by Janus or its affiliates,” Janus and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Fund or that provide services in connection with investments in the Fund. You should consider such arrangements when evaluating any recommendation of the Fund.

Class D Shares are generally no longer being made available to new investors who do not already have a direct account with the Janus funds. The shares are available only to investors who hold accounts directly with the Janus funds, and to immediate family members or members of the same household of an eligible individual investor. Under certain limited circumstances, shareholders of other Janus share classes who no longer wish to hold shares through an intermediary may be eligible to purchase Class D Shares. Eligible investors can purchase Class D Shares directly through Janus by the following methods:

•  By calling Janus XpressLine^tm at 1-888-979-7737, a 24-hour automated phone system;

•  By contacting a Janus representative at 1-800-525-3713 (TDD for the speech and hearing impaired, 1-800-525-0056);

•  By regular mail, Janus, P.O. Box 55932, Boston, MA 02205-5932;

•  By overnight mail, Janus, 30 Dan Road, Suite 55932, Canton, MA 02021-2809; or

•  Through janus.com.

The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading. For more information about the Fund’s policy on excessive trading, refer to “Excessive Trading.”

In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary (or Janus if you hold shares directly with Janus) is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. Until verification of your identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if they are unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.

In an effort to ensure compliance with this law, Janus’ Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

With respect to Class D Shares, the Fund has also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Fund is required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.

Minimum Investment Requirements

Class A Shares, Class C Shares, Class S Shares, and Class T Shares

The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-deferred accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, accounts held through certain wrap programs may not be subject to these minimums. Investors should refer to their intermediary for additional information.

The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares.

Class D Shares

The minimum investment is $2,500 per Fund account for non-retirement accounts. For certain tax-deferred accounts or UGMA/UTMA accounts, the minimum investment is $1,000 without an automatic investment program, or $500 with an automatic investment program of $100 per month.

Class I Shares

The minimum investment is $1 million for institutional investors investing directly with Janus. Institutional investors generally may meet the minimum investment amount by aggregating multiple accounts within the same Fund. Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-deferred accounts or UGMA/UTMA accounts. Directors, officers, and employees of Janus Capital Group Inc. (“JCGI”) and its affiliates, as well as Trustees and officers of the Fund, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-deferred, tax-qualified and retirement plans, and accounts held through certain wrap programs. For additional information, contact your intermediary, plan sponsor, administrator, or a Janus representative, as applicable.

Class R Shares

Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for information regarding account minimums. For all other account types, the minimum investment is $2,500.

Class A Shares, Class C Shares, Class D Shares, Class S Shares, Class I Shares, and Class T Shares

The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed. If you hold shares directly with the Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum. Please note that you may incur a tax liability as a result of a redemption.

The Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.

Systematic Purchase Plan

You may arrange for periodic purchases by authorizing your financial intermediary (or Janus if you hold shares directly with Janus) to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus representative for details.

Initial Sales Charge

Class A Shares

An initial sales charge may apply to your purchase of Class A Shares of the Fund based on the amount invested, as set forth in the table below. The sales charge is allocated between Janus Distributors and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and

C-8

the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

	Class A Shares			Class A Shares
	Sales Charge as a			Sales Charge as a
	Percentage of			Percentage of
Amount of Purchase at Offering Price	Offering Price(1)			Net Amount Invested
Under $50,000		5.75	%		6.10	%
$50,000 but under $100,000		4.50	%		4.71	%
$100,000 but under $250,000		3.50	%		3.63	%
$250,000 but under $500,000		2.50	%		2.56	%
$500,000 but under $1,000,000		2.00	%		2.04	%
$1,000,000 and above		None	(2)		None

(1)	Offering Price includes the initial sales charge.
(2)	A contingent deferred sales charge of 1.00% may apply to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase.

For purchases of Class A Shares of $1,000,000 or greater, from its own assets, Janus Distributors may pay financial intermediaries commissions as follows:

•  1.00% on amounts from $1,000,000 to $4,000,000;

•  plus 0.50% on amounts greater than $4,000,000 to $10,000,000;

•  plus 0.25% on amounts over $10,000,000.

The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.

Qualifying for a Reduction or Waiver of Class A Shares Sales Charge

You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in this Fund or certain other Janus funds) with your current purchase of Class A Shares of the Fund and certain other Janus funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of shares and purchases are described below. Contact your financial intermediary for more information.

Class A Shares of the Fund may be purchased without an initial sales charge by the following persons (and their spouses and children under 21 years of age): (i) registered representatives and other employees of intermediaries that have selling agreements with Janus Distributors to sell Class A Shares; (ii) directors, officers, and employees of JCGI and its affiliates; and (iii) Trustees and officers of the Trust. In addition, the initial sales charge may be waived on purchases of Class A Shares through financial intermediaries that have entered into an agreement with Janus Distributors that allows the waiver of the sales charge.

In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Fund, its agents, or your financial intermediary may not retain this information.

Right of Accumulation.  You may purchase Class A Shares of the Fund at a reduced sales charge determined by aggregating the dollar amount of the new purchase (measured by the offering price) and the total prior day’s net asset value (net amount invested) of all Class A Shares of the Fund and of certain other classes (Class A Shares and Class C Shares of the Trust) of Janus funds then held by you, or held in accounts identified under “Aggregating Accounts,” and applying the sales charge applicable to such aggregate amount. In order for your purchases and holdings to be aggregated for purposes of qualifying for such discount, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The right of accumulation is subject to modification or discontinuance at any time with respect to all shares purchased thereafter.

C-9

Letter of Intent.  You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.

Aggregating Accounts.  To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:

•  trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);

•  solely controlled business accounts; and

•  single participant retirement plans.

To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.

You may access information regarding sales loads, breakpoint discounts, and purchases of the Fund’s shares, free of charge, and in a clear and prominent format, on our website at janus.com/breakpoints, and by following the appropriate hyperlinks to the specific information.

Commission on Class C Shares

Janus Distributors may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to qualified plans or other financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.

EXCHANGES

Contact your financial intermediary, Janus if you hold shares directly with Janus, or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-deferred accounts).

•  You may generally exchange shares of the Fund for shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan.

•  You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will only be processed in instances where there is no contingent deferred sales charge (“CDSC”) on the shares to be exchanged and no initial sales charge on the shares to be received. The Fund’s fees and expenses differ between share classes. Please consider these differences prior to investing in another share class. Contact your financial intermediary or consult your plan documents for additional information.

•  You must meet the minimum investment amount for each fund.

•  The exchange privilege is not intended as a vehicle for short-term or excessive trading. The Fund may suspend or terminate your exchange privilege if you make more than one round trip in the Fund in a 90-day period and may bar future purchases in the Fund or any of the other Janus funds. The Fund will work with intermediaries to apply the Fund’s exchange limit. However, the Fund may not always have the ability to monitor or enforce the trading activity in such accounts. For more information about the Fund’s policy on excessive trading, refer to “Excessive Trading.”

•  The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.

C-10

Waiver of Sales Charges

Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to any initial sales charge of the Fund’s Class A Shares. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. Any CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.

REDEMPTIONS

Redemptions, like purchases, may generally be effected only through financial intermediaries, retirement platforms, and by certain direct investors holding Class D Shares or Class I Shares. Please contact your financial intermediary, Janus if you hold shares directly Janus, or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of shares.

Shares of the Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by the Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares, will normally be sent the business day following receipt of the redemption order.

The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.

The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed. If you hold shares directly with the Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum. Please note that you may incur a tax liability as a result of a redemption.

Large Shareholder Redemptions

Certain accounts or Janus affiliates may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s shares. Redemptions by these accounts of their holdings in the Fund may impact the Fund’s liquidity and NAV. These redemptions may also force the Fund to sell securities, which may negatively impact the Fund’s brokerage costs.

Redemptions In-Kind

Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash. If this occurs, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions.

While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs.

C-11

Systematic Withdrawal Plan

Class A Shares and Class C Shares

You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived through financial intermediaries that have entered into an agreement with Janus Distributors. The maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.

Class D Shares, Class S Shares, Class I Shares, Class R Shares, and Class T Shares

You may arrange for periodic redemptions by authorizing your financial intermediary (or Janus if you hold shares directly with Janus) to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus representative for details.

Contingent Deferred Sales Charge

Class A Shares and Class C Shares

A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.

CDSC Waivers

There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:

•  Upon the death or disability of an account owner;

•  Retirement plans and certain other accounts held through a financial intermediary that has entered into an agreement with Janus Distributors to waive CDSCs for such accounts;

•  Retirement plan shareholders taking required minimum distributions;

•  The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;

•  The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or

•  If the Fund chooses to liquidate or involuntarily redeem shares in your account.

To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.

Reinstatement Privilege

After you have redeemed Class A Shares, you have a one-time right to reinvest the proceeds into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.

EXCESSIVE TRADING

Excessive Trading Policies and Procedures

The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Fund is intended for long-term investment purposes only, and the Fund will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Fund’s exchange limits or excessive trading policies may be cancelled or revoked by the Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus funds may be considered in enforcing these policies and procedures. As described below, however, the Fund may not be able to identify all instances of excessive trading or completely eliminate the possibility of excessive trading. In particular, it may be difficult to identify excessive trading in certain omnibus accounts and other accounts traded through intermediaries. By their nature, omnibus accounts, in which purchases and redemptions of the Fund’s shares by multiple investors are aggregated by the intermediary and presented to the Fund

C-12

on a net basis, may effectively conceal the identity of individual investors and their transactions from the Fund and its agents. This makes the elimination of excessive trading in the accounts impractical without the assistance of the intermediary.

The Fund attempts to deter excessive trading through at least the following methods:

•  exchange limitations as described under “Exchanges;”

•  trade monitoring; and

•  fair valuation of securities as described under “Pricing of Fund Shares.”

Generally, a purchase and redemption of shares from the Fund (i.e., “round trip”) within 90 calendar days may result in enforcement of the Fund’s excessive trading policies and procedures with respect to future purchase orders, provided that the Fund reserves the right to reject any purchase request as explained above.

The Fund monitors for patterns of shareholder frequent trading and may suspend or permanently terminate the exchange privilege of any investor who makes more than one round trip in the Fund over a 90-day period, and may bar future purchases into the Fund and any of the other Janus funds by such investor. The Fund’s excessive trading policies generally do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus funds by a Janus “fund of funds,” which is a fund that primarily invests in other Janus mutual funds; and (iii) identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with existing target allocations.

The Fund’s Trustees may approve from time to time a redemption fee to be imposed by any Janus fund, subject to 60 days’ notice to shareholders of that fund.

Investors who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Fund’s excessive trading policies and procedures and may be rejected in whole or in part by the Fund. The Fund, however, cannot always identify or reasonably detect excessive trading that may be facilitated by financial intermediaries or made difficult to identify through the use of omnibus accounts by those intermediaries that transmit purchase, exchange, and redemption orders to the Fund, and thus the Fund may have difficulty curtailing such activity. Transactions accepted by a financial intermediary in violation of the Fund’s excessive trading policies may be cancelled or revoked by the Fund by the next business day following receipt by the Fund.

In an attempt to detect and deter excessive trading in omnibus accounts, the Fund or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Fund’s ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.

Certain transactions in Fund shares, such as periodic rebalancing through intermediaries (no more frequently than every 60 days) or those which are made pursuant to systematic purchase, exchange, or redemption programs generally do not raise excessive trading concerns and normally do not require application of the Fund’s methods to detect and deter excessive trading.

The Fund also reserves the right to reject any purchase request (including exchange purchases) by any investor or group of investors for any reason without prior notice, including, in particular, if the trading activity in the account(s) is deemed to be disruptive to the Fund. For example, the Fund may refuse a purchase order if the Fund’s investment personnel believe they would be unable to invest the money effectively in accordance with the Fund’s investment policies or the Fund would otherwise be adversely affected due to the size of the transaction, frequency of trading, or other factors.

The Fund’s policies and procedures regarding excessive trading may be modified at any time by the Fund’s Trustees.

Excessive Trading Risks

Excessive trading may present risks to the Fund’s long-term shareholders. Excessive trading into and out of the Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.

Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not

C-13

invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the Fund, which negatively impacts long-term shareholders. Although the Fund has adopted fair valuation policies and procedures intended to reduce the Fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies, under such circumstances there is potential for short-term arbitrage trades to dilute the value of Fund shares.

Although the Fund takes steps to detect and deter excessive trading pursuant to the policies and procedures described in this Prospectus and approved by the Trustees, there is no assurance that these policies and procedures will be effective in limiting excessive trading in all circumstances. For example, the Fund may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Fund and its agents. This makes the Fund’s identification of excessive trading transactions in the Fund through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Fund encourages intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Fund cannot eliminate completely the possibility of excessive trading.

Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Fund.

AVAILABILITY OF PORTFOLIO HOLDINGS INFORMATION

The Mutual Fund Holdings Disclosure Policies and Procedures adopted by Janus and all mutual funds managed within the Janus fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes policies and procedures with respect to disclosure of portfolio holdings.

•  Full Holdings.  The Fund is required to disclose its complete holdings in the quarterly holdings report on Form N-Q within 60 days of the end of the first and third fiscal quarters, and in the annual report and semiannual report to Fund shareholders. These reports (i) are available on the SEC’s website at http://www.sec.gov; (ii) may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. (information on the Public Reference Room may be obtained by calling 1-800-SEC-0330); and (iii) are available without charge, upon request, by calling a Janus representative at 1-800-525-0020 (toll free). Portfolio holdings, consisting of at least the names of the holdings, are generally available on a calendar quarter-end basis with a 30-day lag. Holdings are generally posted approximately two business days thereafter under Full Holdings for the Fund at janus.com/info (or under the Fund’s Holdings & Details tab at janus.com/allfunds if you hold Class D Shares).

The Fund may provide, upon request, historical full holdings on a monthly basis for periods prior to the previous quarter-end subject to a written confidentiality agreement.

•  Top Holdings.  The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag.

•  Other Information.  The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top performance contributors/detractors (consisting of security names in alphabetical order), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag. Top performance contributors/detractors provided at calendar quarter-end may include the percentage of contribution/detraction to Fund performance.

Full portfolio holdings will remain available on the Janus websites at least until a Form N-CSR or Form N-Q is filed with the SEC for the period that includes the date as of which the website information is current. Funds disclose their short positions, if applicable, only to the extent required in regulatory reports. Janus may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by Janus’ Chief Investment Officer(s) or their delegates. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s combined SAI, which is incorporated herein.

SHAREHOLDER COMMUNICATIONS

Your financial intermediary or plan sponsor (or Janus if you hold shares directly with Janus) is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.

Your financial intermediary or plan sponsor (or Janus if you hold shares directly with Janus) is responsible for providing annual and semiannual reports, including the financial statements of the Fund. These reports show the Fund’s investments and the market value of such investments, as well as other information about the Fund and its operations. Please contact your financial intermediary or plan sponsor (or Janus if you hold shares directly with Janus) to obtain these reports. The Fund’s fiscal year ends September 30.

DISTRIBUTIONS

To avoid taxation of the Fund, the Internal Revenue Code requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. The Fund’s income from certain dividends, interest, and any net realized short-term capital gains are paid to shareholders as ordinary income dividends. Certain dividend income may be reported to shareholders as “qualified dividend income,” which is generally subject to reduced rates of taxation. Net realized long-term capital gains, if any, are paid to shareholders as capital gains distributions, regardless of how long shares of the Fund have been held. Distributions are made at the class level, so they may vary from class to class within the Fund.

Distribution Schedule

Dividends from net investment income for Worldwide Fund are normally declared and distributed in December. In addition, distributions of capital gains are normally declared and distributed in December. If necessary, dividends and net capital gains may be distributed at other times as well.

How Distributions Affect the Fund’s NAV

Distributions are paid to shareholders as of the record date of a distribution of the Fund, regardless of how long the shares have been held. Undistributed dividends and net capital gains are included in the Fund’s daily NAV. The share price of the Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, the Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.

“Buying a Dividend”

If you purchase shares of the Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-deferred account, dividends paid to you would be included in your gross income for tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.

For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary or Janus if you hold shares directly with Janus. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-deferred plan or account.

TAXES

As with any investment, you should consider the tax consequences of investing in the Fund. Any time you sell or exchange shares of a fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction; whether the gain or loss is long-term or short-term depends on how long you owned the shares. Any tax liabilities generated by your transactions are your responsibility.

The following discussion does not apply to qualified tax-deferred accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser if you have any questions. Additionally, state or local taxes may apply to your investment, depending upon the laws of your state of residence.

C-15

Taxes on Distributions

Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. When gains from the sale of a security held by the Fund are paid to shareholders, the rate at which the gain will be taxed to shareholders depends on the length of time the Fund held the security. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Generally, account tax information will be made available to shareholders on or before January 31st of each year. Information regarding distributions may also be reported to the Internal Revenue Service.

Distributions made by the Fund with respect to shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan.

Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 591/2, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor.

The Fund may be required to withhold U.S. federal income tax on all distributions and redemptions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the Internal Revenue Service that they are subject to backup withholding. The current backup withholding rate is applied.

When shareholders sell Fund shares from a taxable account, they typically receive information on their tax forms that calculates their gain or loss using the average cost method. Prior to January 1, 2012, this information was not reported to the IRS, and shareholders had the option of calculating gains or losses using an alternative IRS permitted method. In accordance with legislation passed by Congress in 2008, however, your intermediary (or the Fund, if you hold shares directly with Janus) began reporting cost basis information to the IRS for shares purchased on or after January 1, 2012 and sold thereafter. Your intermediary (or the Fund, if you hold shares directly with Janus) will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method, unless you hold shares directly with Janus in which case the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the new cost basis reporting laws apply to you and your investments.

Taxation of the Fund

Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders as a foreign tax credit. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible. Certain transactions or strategies utilized by the Fund may generate nonqualified income that can impact an investor’s taxes.

The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income taxes twice. Funds that invest in partnerships may be subject to state tax liabilities.

FINANCIAL HIGHLIGHTS

The financial highlights tables are intended to help you understand each Fund’s financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if

C-16

applicable. The information for the fiscal periods shown has been audited by PricewaterhouseCoopers LLP, whose report, along with each Fund’s financial statements, is included in the Annual Report, which is available upon request, and incorporated by reference into each Fund’s SAI.

The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the shares of each Fund (assuming reinvestment of all dividends and distributions).

Class D Shares of each Fund commenced operations on February 16, 2010, after the restructuring of each Fund’s Class J Shares, the predecessor share class. The financial highlights shown for periods prior to February 16, 2010 reflect financial results for the Class J Shares of each Fund. If Class D Shares had been available, the financial results shown may have been different.

Effective February 16, 2010, Class J Shares were renamed Class T Shares and the eligibility requirements changed so that only clients investing through a third-party intermediary may purchase Class T Shares.

APPENDIX D

GLOSSARY OF INVESTMENT TERMS

This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Proxy Statement/Prospectus.

EQUITY AND DEBT SECURITIES

Average-Weighted Effective Maturity is a measure of a bond’s maturity. The stated maturity of a bond is the date when the issuer must repay the bond’s entire principal value to an investor. Some types of bonds may also have an “effective maturity” that is shorter than the stated date due to prepayment or call provisions. Securities without prepayment or call provisions generally have an effective maturity equal to their stated maturity. Average-weighted effective maturity is calculated by averaging the effective maturity of bonds held by a Fund with each effective maturity “weighted” according to the percentage of net assets that it represents.

Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality. If a Fund purchases a participation interest, it may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender. Additional risks are involved in purchasing assignments. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. The Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of any collateral from a secured loan would satisfy a borrower’s obligations or that any collateral could be liquidated. A Fund may have difficulty trading assignments and participations to third parties or selling such securities in secondary markets, which in turn may affect the Fund’s NAV.

Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.

Certificates of Participation (“COPs”) are certificates representing an interest in a pool of securities. Holders are entitled to a proportionate interest in the underlying securities. Municipal lease obligations are often sold in the form of COPs. Refer to “Municipal lease obligations” below.

Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to investors seeking to invest idle cash. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended (the “1933 Act”).

Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.

Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.

Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.

Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).

Duration is the time it will take investors to recoup their investment in a bond. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the

D-1

percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity.

Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.

Exchange-traded funds (“ETFs”) are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.

High-yield/high-risk bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”

Industrial development bonds are revenue bonds that are issued by a public authority but which may be backed only by the credit and security of a private issuer and may involve greater credit risk. Refer to “Municipal securities” below.

Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis. These securities involve prepayment risk, which is the risk that the underlying mortgages or other debt may be refinanced or paid off prior to their maturities during periods of declining interest rates. In that case, a Fund may have to reinvest the proceeds from the securities at a lower rate. Potential market gains on a security subject to prepayment risk may be more limited than potential market gains on a comparable security that is not subject to prepayment risk.

Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts for property or equipment. Lease obligations may not be backed by the issuing municipality’s credit and may involve risks not normally associated with general obligation bonds and other revenue bonds. For example, their interest may become taxable if the lease is assigned and the holders may incur losses if the issuer does not appropriate funds for the lease payments on an annual basis, which may result in termination of the lease and possible default.

Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.

Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.

Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.

Pay-in-kind bonds are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.

D-2

Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.

Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans.

Rule 144A securities are securities that are not registered for sale to the general public under the 1933 Act, but that may be resold to certain institutional investors.

Standby commitment is a right to sell a specified underlying security or securities within a specified period of time and at an exercise price equal to the amortized cost of the underlying security or securities plus accrued interest, if any, at the time of exercise, that may be sold, transferred, or assigned only with the underlying security or securities. A standby commitment entitles the holder to receive same day settlement, and will be considered to be from the party to whom the investment company will look for payment of the exercise price.

Step coupon bonds are high-quality issues with above-market interest rates and a coupon that increases over the life of the bond. They may pay monthly, semiannual, or annual interest payments. On the date of each coupon payment, the issuer decides whether to call the bond at par, or whether to extend it until the next payment date at the new coupon rate.

Strip bonds are debt securities that are stripped of their interest (usually by a financial intermediary) after the securities are issued. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities of comparable maturity.

Tender option bonds are relatively long-term bonds that are coupled with the option to tender the securities to a bank, broker-dealer, or other financial institution at periodic intervals and receive the face value of the bond. This investment structure is commonly used as a means of enhancing a security’s liquidity.

U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.

Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate (the “underlying index”). The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.

Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.

Zero coupon bonds are debt securities that do not pay regular interest at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.

FUTURES, OPTIONS, AND OTHER DERIVATIVES

Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.

Derivatives are financial instruments whose performance is derived from the performance of another asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward contracts, swaps, and futures contracts.

Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be

D-3

based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form. An investment in equity-linked notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities, and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.

Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).

Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.

Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. A Fund may also buy options on futures contracts. An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.

Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments. A Fund bears the market risk of an investment in the underlying instruments, as well as the credit risk of the issuer.

Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).

Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.

Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.

Participatory notes are derivative securities which are linked to the performance of an underlying Indian security and which allow investors to gain market exposure to Indian securities without trading directly in the local Indian market.

Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period.

OTHER INVESTMENTS, STRATEGIES, AND/OR TECHNIQUES

Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles at the end of each day.

Diversification is a classification given to a fund under the 1940 Act. Funds are classified as either “diversified” or “nondiversified.” To be classified as “diversified” under the 1940 Act, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as “nondiversified” under the 1940 Act, on the other hand, has the flexibility to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” However, because the appreciation or depreciation of a

D-4

single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.

Industry concentration for purposes under the 1940 Act is the investment of 25% or more of a Fund’s total assets in an industry or group of industries.

Leverage is when a Fund increases its assets available for investment using borrowings or similar transactions. Because short sales involve borrowing securities and then selling them, a Fund’s short sales effectively leverage the Fund’s assets. The use of leverage may make any change in a Fund’s NAV even greater and thus result in increased volatility of returns. A Fund’s assets that are used as collateral to secure the short sales may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage also creates interest expense that may lower a Fund’s overall returns.

Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.

Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.

Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash. These securities involve the risk that the seller will fail to repurchase the security, as agreed. In that case, a Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.

Reverse repurchase agreements involve the sale of a security by a Fund to another party (generally a bank or dealer) in return for cash and an agreement by the Fund to buy the security back at a specified price and time. This technique will be used primarily to provide cash to satisfy unusually high redemption requests, or for other temporary or emergency purposes.

Short sales in which a Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain. For short sales, the Fund will incur a loss if the value of a security increases during this period because it will be paying more for the security than it has received from the purchaser in the short sale. If the price declines during this period, a Fund will realize a short-term capital gain. Although a Fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security.

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. A Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

APPENDIX E

PERFORMANCE FEE EXAMPLE

The following hypothetical examples are intended to help you understand the performance fee calculation assuming consummation of the Merger, including application of the three-year waiver to the Performance Adjustment component of the management fee agreed to by Janus. The actual performance fee paid by the Combined Fund, including any waivers, will be different from that shown below as it will be based on actual performance and assets as of the Merger Date and going forward.

The Performance Adjustment is calculated using the trailing 36-month relative performance of the Fund to the MSCI World Index^sm, the trailing 36-month average net assets of the Fund, and the hurdle rates at which the Performance Adjustment changes.

For the calculation examples below, the Performance Adjustment and waiver for the Combined Fund is calculated for month 6 and month 13 following the completion of the Merger.

All calculations shown below assume the Merger is completed on the last day of the 2012 calendar year so month 6 is June 2013 and month 13 is January 2014.

For purposes of calculating the actual Performance Adjustment accrual, Global Research Fund’s performance and accounting history will be used relative to the MSCI World Index^sm.

For purposes of calculating the waiver, if any, Worldwide Fund’s performance and accounting history will be used for periods prior to the Merger.

Key assumptions used when calculating projected Performance Adjustments and waivers:

•  The Merger is effective December 31, 2012

•  Fund performance equals benchmark performance (MSCI World Index^sm) for all future periods (August 1, 2012 − December 31, 2015)

•  Fund performance and benchmark performance are 0.00% for all future periods

•  Net flows are $0 for all future periods

Month 6 Step 1 – Calculate the relative performance and Performance Adjustments

Global Research Fund trailing 36-month relative performance through May 2013. The Performance Adjustment is booked one month in arrears so the Performance Adjustment calculation for June 2013 is based on the relative performance through May 2013:

Notes to Pro Forma Financial Statements (Unaudited)

The following section describes the organization and significant accounting policies and provides more detailed information about the schedules and tables that appear throughout this report. In addition, the Notes to Pro Forma Financial Statements explain the methods used in preparing and presenting this report.

1. Organization and Significant Accounting Policies

Janus Global Research Fund and Janus Worldwide Fund (individually, a “Fund” and collectively, the “Funds”) are series funds. The Funds are part of Janus Investment Fund (the “Trust”), which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust offers forty-five funds which include multiple series of shares, with differing investment objectives and policies. The Funds invest primarily in equity securities and are each classified as diversified, as defined in the 1940 Act.

The accompanying unaudited pro forma financial statements are presented to show the effect of the proposed merger of Janus Global Research Fund into Janus Worldwide Fund. If approved by shareholders, Janus Global Research Fund investors will receive a number of full and fractional shares of Janus Worldwide Fund approximately equivalent in dollar value to their shares held in Janus Global Research Fund. Specifically, all or substantially all of the assets of Janus Global Research Fund will be transferred to Janus Worldwide Fund solely in exchange for shares of Janus Worldwide Fund with a value approximately equal to the value of Janus Global Research Fund’s assets net of liabilities, and the assumption by Janus Worldwide Fund of all liabilities of Janus Global Research Fund. Immediately following the transfer, the shares of Janus Worldwide Fund received by Janus Global Research Fund will be distributed pro rata to Janus Global Research Fund shareholders and Janus Global Research Fund will subsequently be liquidated. The purpose of the merger is based on similarities of the Funds’ investment objectives, strategies and policies, as well as the anticipated expense efficiencies due to the larger asset base of the combined fund after the merger. Janus Global Research Fund will be deemed the performance and accounting survivor for the merger.

The reorganization is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes. The unaudited pro forma combined financial statements are presented for informational purposes and may not be representative of what the actual combined financial statements would have been had the reorganization occurred at October 1, 2011. The unaudited pro forma schedules of investments and statements of assets and liabilities reflect the financial position of the Funds at September 30, 2012 as if the reorganization had occurred on that date. The unaudited pro forma statements of operations reflect the results of operations of the Funds for the twelve- month period ended September 30, 2012 as if the reorganization had occurred on October 1, 2011. In accordance with accounting principles generally accepted in the United States of America, the historical cost of investment securities will be carried forward to the surviving fund and the results of operations for pre-combination periods of the surviving fund will not be restated. The accompanying pro forma financial statements should be read in conjunction with the financial statements of the Funds included in their annual reports dated September 30, 2012.

The following accounting policies have been followed by the Funds and are in conformity with accounting principles generally accepted in the United States of America.

Investment Valuation

Securities are valued at the last sales price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities traded on over-the-counter (“OTC”) markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees. Short-term securities with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Short positions shall be valued in accordance with the same methodologies, except that in the event that a last sale price is not available, the latest ask price shall be used instead of a bid price. Foreign securities and currencies are converted

13

to U.S. dollars using the applicable exchange rate in effect as of the daily close of the New York Stock Exchange (“NYSE”). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the Funds are identified between the closing of their principal markets and the time the net asset value (“NAV”) is determined, securities may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Funds’ Trustees. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a nonsignificant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. Restricted and illiquid securities are valued in accordance with procedures established by the Funds’ Trustees.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held at the date of the financial statements. Net unrealized appreciation or depreciation of investments and foreign currency translations arise from changes in the value of assets and liabilities, including investments in securities held at the date of the financial statements, resulting from changes in the exchange rates and changes in market prices of securities held. Currency gains and losses are also calculated on payables and receivables that are denominated in foreign currencies. The payables and receivables are generally related to foreign security transactions and income translations. Foreign currency-denominated assets and forward currency contracts may involve more risks than domestic transactions, including currency risk, political and economic risk, regulatory risk and equity risk. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar.

Valuation Inputs Summary

In accordance with the Financial Accounting Standards Board (“FASB”) guidance, the Funds utilize the “Fair Value Measurements” to define fair value, establish a framework for measuring fair value, and expand disclosure requirements regarding fair value measurements. The Fair Value Measurement Standard does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. This standard emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. Various inputs are used in determining the value of the Funds’ investments defined pursuant to this standard. These inputs are summarized into three broad levels:

Level 1 — Quoted prices in active markets for identical securities.

Level 2 — Prices determined using other significant observable inputs. Observable inputs are inputs that reflect the assumptions market participants would use in pricing a security and are developed based on market data obtained from sources independent of the reporting entity. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others.

Debt securities are valued in accordance with the evaluated bid price supplied by the pricing service and generally categorized as Level 2 in the hierarchy. Securities traded on OTC markets and listed securities for which no sales are

14

reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees and are categorized as Level 2 in the hierarchy. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value and are categorized as Level 2 in the hierarchy. Other securities that may be categorized as Level 2 in the hierarchy include, but are not limited to, preferred stocks, bank loans, American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs), warrants, swaps, investments in mutual funds, OTC options, and forward contracts. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. These are generally categorized as Level 2 in the hierarchy.

Level 3 — Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable or deemed less relevant (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the factors market participants would use in pricing the security and would be based on the best information available under the circumstances.

For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used in employing valuation techniques such as the market approach, the income approach, or the cost approach, as defined under the FASB Guidance. These are categorized as Level 3 in the hierarchy.

During the twelve-month period ending September 30, 2012, there have been no significant changes in valuation techniques used in valuing any such positions held by the Funds.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of inputs used as of September 30, 2012 to value each Fund’s investments in securities and other financial instruments is included in the “Valuation Inputs Summary” and “Level 3 Valuation Reconciliation of Assets” (if applicable) on the Pro Forma Notes to Schedules of Investments.

The Funds adopted FASB Accounting Standards Update “Fair Value Measurements and Disclosures” (the “Update”). This Update applies to a Fund’s disclosures about transfers in and out of Level 1 and Level 2 of the fair value hierarchy and the reasons for the transfers. Disclosures about the valuation techniques and inputs used to measure fair value for investments that fall in either Level 2 or Level 3 fair value hierarchy are summarized under the Level 2 and Level 3 categories listed above. There were no Level 3 securities during the fiscal period.

In May 2011, the FASB issued Accounting Standards Update, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements.” The Accounting Standards Update requires disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Funds shall provide quantitative information about the significant unobservable inputs used in the fair value measurement. To meet the objective of the quantitative disclosure, the Funds may need to further disaggregate to provide more meaningful information about the significant unobservable inputs used and how these inputs vary over time.

The Funds are not required to create quantitative information to comply with this disclosure requirement if quantitative unobservable inputs are not developed by the Funds when measuring fair value (for example, when a Fund uses prices from prior transactions or third-party pricing information without adjustment). However, when providing this disclosure, the Funds cannot ignore quantitative unobservable inputs that are significant to the fair value measurement and are reasonably available to the Funds.

In addition, the Accounting Standards Update requires the Funds to provide a narrative sensitivity disclosure of the fair value measurement changes in unobservable inputs and the interrelationships between those unobservable inputs for fair value measurements categorized with Level 3 of the fair value hierarchy.

The following table shows transfers between Level 1 and Level 2 of the fair value hierarchy during the period ended September 30, 2012.

15

	Transfers Out Of
	Level 2
Fund	to Level 1
Janus Global Research Fund	$	46,308,762
Janus Worldwide Fund		508,071,275

Financial assets were transferred from Level 2 to Level 1 since certain foreign equity prices were applied a fair valuation adjustment factor at the beginning of the fiscal year and no factor was applied at the end of the period.

The Funds recognize transfers between the levels as of the beginning of the period.

Derivative Instruments

The Funds may invest in various types of derivatives, which may at times result in significant derivative exposure. A derivative is a financial instrument whose performance is derived from the performance of another asset. The Funds may invest in derivative instruments including, but not limited to: futures contracts, put options, call options, options on future contracts, options on foreign currencies, swaps, forward contracts, structured investments, and other equity-linked derivatives. Each derivative instrument that was held by one or more of the Funds during the period ended September 30, 2012 is discussed in further detail below. A summary of derivative activity by Fund is reflected in the tables at the end of this section.

The Funds may use derivative instruments for hedging (to offset risks associated with an investment, currency exposure, or market conditions) or for speculative (to seek to enhance returns) purposes. When the Funds invest in a derivative for speculative purposes, the Funds will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. The Funds may not use any derivative to gain exposure to an asset or class of assets in which they would be prohibited by their respective investment restrictions from purchasing directly. The Funds’ ability to use derivative instruments may also be limited by tax considerations.

Investments in derivatives in general are subject to market risks that may cause their prices to fluctuate over time. Investments in derivatives may not directly correlate with the price movements of the underlying instrument. As a result, the use of derivatives may expose the Funds to additional risks that they would not be subject to if they invested directly in the securities underlying those derivatives. The use of derivatives may result in larger losses or smaller gains than otherwise would be the case. Derivatives can be volatile and may involve significant risks, including, but not limited to, counterparty risk, credit risk, currency risk, equity risk, index risk, interest rate risk, leverage risk, and liquidity risk, as described below.

Derivatives may generally be traded OTC or on an exchange. Derivatives traded OTC, such as options and structured notes, are agreements that are individually negotiated between parties and can be tailored to meet a purchaser’s needs.

OTC derivatives are not guaranteed by a clearing agency and may be subject to increased credit risk. In an effort to mitigate credit risk associated with derivatives traded OTC, the Funds may enter into collateral agreements with certain counterparties whereby, subject to certain minimum exposure requirements, a Fund may require the counterparty to post collateral if the Fund has a net aggregate unrealized gain on all OTC derivative contracts with a particular counterparty. There is no guarantee that counterparty exposure is reduced and these arrangements are dependent on Janus Capital Management LLC’s (“Janus Capital”) ability to establish and maintain appropriate systems and trading.

In pursuit of their investment objectives, each Fund may seek to use derivatives to increase or decrease exposure to the following market risk factors:

16

• Counterparty Risk — Counterparty risk is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to a Fund.

• Credit Risk — Credit risk is the risk an issuer will be unable to make principal and interest payments when due, or will default on its obligations.

• Currency Risk — Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

• Equity Risk — Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

• Index Risk — If the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, a Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

• Interest Rate Risk — Interest rate risk is the risk that the value of fixed-income securities will generally decline as prevailing interest rates rise, which may cause a Fund’s NAV to likewise decrease, and vice versa.

• Leverage Risk – Leverage risk is the risk associated with certain types of leveraged investments or trading strategies pursuant to which relatively small market movements may result in large changes in the value of an investment. A Fund creates leverage by using borrowed capital to increase the amount invested, or investing in instruments, including derivatives, where the investment loss can exceed the original amount invested. Certain investments or trading strategies that involve leverage can result in losses that greatly exceed the amount originally invested.

• Liquidity Risk – Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

Forward Foreign Currency Exchange Contracts

A forward foreign currency exchange contract (“forward currency contract”) is an obligation to buy or sell a foreign currency at a future date at a negotiated rate. The Funds may enter into forward currency contracts for hedging purposes, including, but not limited to, reducing exposure to changes in foreign currency exchange rates on foreign portfolio holdings and locking in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. The Funds may also invest in forward currency contracts for nonhedging purposes such as seeking to enhance returns. The Funds are subject to currency risk in the normal course of pursuing their investment objectives through their investments in forward currency contracts.

The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract is included in “Net realized gain/(loss) from investment and foreign currency transactions” on the Pro Forma Statements of Operations (if applicable). Forward currency contracts held by the Funds are fully collateralized by other securities, which are denoted on the accompanying Pro Forma Schedules of Investments (if applicable). The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts. Such collateral is in the possession of the Funds’ custodian.

Options Contracts

An options contract provides the purchaser with the right, but not the obligation, to buy (call option) or sell (put option) a financial instrument at an agreed upon price. The Funds may purchase or write covered and uncovered put and call options on swap contracts (“swaptions”), futures contracts, and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds are subject to interest rate risk, liquidity risk, equity risk, and currency risk in the normal course of pursuing their investment objectives through their investments in options

17

contracts. The Funds may use options contracts to hedge against changes in interest rates, the values of equities, or foreign currencies. The Funds may utilize American-style and European-style options. An American-style option is an option contract that can be exercised at any time between the time of purchase and the option’s expiration date. A European-style option is an option contract that can only be exercised on the option’s expiration date. The Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in long-term equity anticipation securities, which are long-term options contracts that can be maintained for a period of up to three years. The Funds may also enter into a swaption contract which grants the purchaser the right, but not the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. Entering into a swaption contract involves, to varying degrees, the elements of credit, market and interest rate risk, associated with both option contracts and swap contracts. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the Funds receive a premium and become obligated to sell or purchase the underlying security at a fixed price, upon exercise of the option. In writing an option, the Funds bear the risk of an unfavorable change in the price of the security underlying the written option. Exercise of an option written by the Funds could result in the Funds buying or selling a security at a price different from the current market value.

When an option is exercised, the proceeds on sales for a written call option, the purchase cost for a written put option, or the cost of the security for a purchased put or call option are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and OTC put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

Options traded on an exchange are regulated and the terms of the options are standardized. Options traded OTC expose the Funds to counterparty risk in the event that the counterparty does not perform. This risk is mitigated by having a netting arrangement between the Funds and the counterparty and by having the counterparty post collateral to cover the Funds’ exposure to the counterparty.

Holdings of the Funds designated to cover outstanding written options are noted on the Pro Forma Schedules of Investments (if applicable). Options written are reported as a liability on the Pro Forma Statements of Assets and Liabilities as “Options written at value” (if applicable). Realized gains and losses are reported as “Net realized gain/(loss) from written options contracts” on the Pro Forma Statements of Operations (if applicable).

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the options are exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the options are exercised. The risk in buying options is that the Funds pay a premium whether or not the options are exercised. The use of such instruments may involve certain additional risks as a result of unanticipated movements in the market. A lack of correlation between the value of an instrument underlying an option and the asset being hedged, or unexpected adverse price movements, could render the Funds’ hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. There is no limit to the loss the Funds may recognize due to written call options.

Written option activity for the fiscal year ended September 30, 2012 is indicated in the table below:

In accordance with FASB guidance, the Funds adopted the provisions for “Derivatives and Hedging,” which require qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements.

The following tables, grouped by derivative type, provide information about the fair value and location of derivatives within the Pro Forma Statements of Assets and Liabilities as of September 30, 2012.

Additional Investment Risk

It is important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in NAV, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude a Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will

continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the” Dodd-Frank Act”) in July 2010 which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity (or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

In addition, European markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels, and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal, and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and worldwide sellers of credit default swaps linked to that country’s creditworthiness. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of all European countries, which in turn may have a material adverse effect on a Fund’s investments in such countries, other countries that depend on European countries for significant amounts of trade or investment, or issuers with exposure to European debt.

Certain areas of the world have historically been prone to and economically sensitive to environmental events such as, but not limited to, hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, tornadoes, mudslides, or other weather-related phenomena. Such disasters, and the resulting physical or economic damage, could have a severe and negative impact on a Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses as they would under normal conditions. Adverse weather conditions may also have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The extent of a Fund’s exposure to counterparty risk in respect to financial assets approximates its carrying value as recorded on the Fund’s Pro Forma Statement of Assets and Liabilities.

A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby a Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures and options. A Fund intends to enter into financial transactions with counterparties that Janus Capital believes to be creditworthy at the time of the transaction. There is always the risk that Janus Capital’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

21

Emerging Market Investing

Each Fund may invest in securities of issuers or companies from or with exposure to one of more “developing countries” or “emerging markets.” Investing in emerging markets may involve certain risks and considerations not typically associated with investing in the United States and imposes risks greater than, or in addition to, the risks associated with investing in securities of more developed foreign countries. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Funds’ investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Funds’ investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.

Exchange-Traded Funds

The Funds may invest in exchange-traded funds which generally are index-based investment companies that hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Investment Advisory Agreements and Other Transactions with Affiliates

Each Fund pays Janus Capital a management fee which is calculated daily and paid monthly. The following table reflects each Fund’s base fee rate (expressed as an annual rate).

	Base Fee (%)
Fund	(annual rate)
Janus Global Research Fund		0.64
Janus Worldwide Fund		0.60
Pro Forma Combined Fund		0.60

For Janus Global Research Fund and Janus Worldwide Fund, the management fee rate is determined by calculating a base fee and applying a performance adjustment. The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index, as shown below:

Fund		Benchmark Index
Janus Global Research Fund	MSCI World Growth Index
Janus Worldwide Fund	MSCI World Index SM
Pro Forma Combined Fund	MSCI World Index SM

The calculation of the performance adjustment applies as follows:

22

Management Fee = Base Fee Rate +/– Performance Adjustment

The management fee rate paid to Janus Capital by each Fund consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the management fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period is a rolling 36-month period.

For purposes of determining the pro forma performance fee calculation, the management fee rate for the combined fund is calculated by applying the annual base management fee rate of 0.60% to the combined fund’s average daily net assets, plus or minus the Performance Adjustment which is based on the performance of Janus Global Research Fund relative to the MSCI World Index.

No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which a Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The management fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After Janus Capital determines whether the Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares against the cumulative investment record of that Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund.

It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

Janus Capital has contractually agreed to waive each Fund’s total annual fund operating expenses (excluding any Performance Adjustments to management fees, the distribution and shareholder servicing fees, administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees for Class A Shares, Class C Shares, and Class I Shares), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) to 1.00% for each Fund, until at least February 1, 2013. The contractual waiver may be terminated or modified prior to this date only at the discretion of the Board of Trustees.

23

In addition, for a three-year period, Janus Capital has agreed to waive the Performance Adjustment to the management fee to a level that is at least that of the management fee paid by Janus Worldwide Fund by using Janus Worldwide Fund’s performance history for periods prior to the merger and comparing it to the performance fee of the combined fund (which is based on Janus Global Research Fund’s performance history for periods prior to the merger) to determine the amount of any waiver. Essentially, the management fee rate paid by the combined fund will reflect the lower of (i) the actual management fee rate using Janus Global Research Fund’s performance and assets for periods prior to the merger to calculate the Performance Adjustment, or (ii) the management fee rate that would have been paid if Janus Worldwide Fund’s performance and larger assets were used to calculate the Performance Adjustment for periods prior to the merger.

This means that while the fee waiver is in effect, shareholders of the combined fund will likely pay less in management fees than if the merger did not take place. However, when the waiver is removed, the management fee rate paid by the combined fund will reflect the actual performance of the combined fund relative to the MSCI World Index ^SM during the 36 months prior to that date, which could be higher or lower than the management fee rate paid monthly during the three-year waiver period. To the extent the combined fund outperforms the MSCI World Index ^SM after the date of the merger a shareholder could see an increase, and possibly a significant increase, in the management fee rate paid to Janus by the combined fund when the waiver is eliminated. That increase would also mean that Janus could earn more in management fees going forward than it otherwise would if the merger had not occurred. In addition, the three-year waiver could initially result in better performance for the combined fund. However, once the waiver is removed, the management fee rate may be higher than it would have been without the three-year waiver. This could result if the combined fund outperforms the MSCI World Index ^SM to a greater extent during the three-year waiver period as a result of the waiver. Further, the historical performance of Global Research Fund has typically outperformed the MSCI World Index ^SM to a greater extent than it has outperformed the current benchmark index for the Global Research Fund, which means it theoretically would be easier for Janus to earn a higher management fee rate. However, whether this outperformance continues will depend on the performance of the combined fund relative to the MSCI World Index ^SM, which is not possible to predict.

Capital Shares

The pro forma net asset value per share assumes the issuance of shares of Janus Worldwide Fund that would have been issued at September 30, 2012, in connection with the proposed reorganization. The number of shares assumed to be issued is equal to the net asset value of shares of Janus Global Research Fund, as of September 30, 2012 divided by the net asset value per share of the shares of Janus Worldwide Fund as of September 30, 2012. The pro forma number of shares outstanding, by class, for the combined fund consists of the following at September 30, 2012:

	Shares of Janus		Additional Shares		Total Outstanding
	Worldwide Fund		Assumed Issued in		Shares Post-
Class of Shares	Pre-Combination		Reorganization		Combination
Class A Shares		46,637		248,513		295,150

Class T Shares		17,609,643		2,487,877		20,097,520

24

Federal Income Taxes

The Funds intend to continue to qualify as regulated investment companies by complying with the provisions available to certain investment companies, as defined in applicable sections of the Internal Revenue Code, and to make distributions of taxable income sufficient to relieve it from all, or substantially all, Federal income taxes. The tax cost of investments will remain unchanged for the combined fund.

INVESTMENT OBJECTIVE

Janus Asia Equity Fund seeks long-term growth of capital.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. Each share class has different expenses, but represents an investment in the same Fund. For Class A Shares, you may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Janus mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial professional and in the “Purchases” section on page 80 of the Fund’s Prospectus and in the “Purchases” section on page 90 of the Fund’s Statement of Additional Information.

Net Annual Fund Operating Expenses After Fee Waiver(2)	1.58%	2.33%	1.83%	1.33%	1.58%

(1)

Since the Fund is new, Other Expenses are based on the estimated expenses that the Fund expects to incur in its initial fiscal period.

(2)

Janus Capital has contractually agreed to waive the Fund’s total annual fund operating expenses (excluding any performance adjustments to management fees, the distribution and shareholder servicing fees – applicable to Class A Shares, Class C Shares, and Class S Shares; administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees); brokerage commissions; interest; dividends; taxes; acquired fund fees and expenses; and extraordinary expenses) to 1.25% until at least February 1, 2013. The contractual waiver may be terminated or modified prior to this date only at the discretion of the Board of Trustees.

EXAMPLE:

The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses without waivers remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If Shares are redeemed:	1 Year		3 Years
Class A Shares	$	945	$	1,696
Class C Shares	$	568	$	1,408
Class S Shares	$	406	$	1,230

2 ï Janus Asia Equity Fund

If Shares are redeemed:	1 Year		3 Years
Class I Shares	$	359	$	1,091
Class T Shares	$	381	$	1,158

If Shares are not redeemed:	1 Year		3 Years
Class A Shares	$	945	$	1,696
Class C Shares	$	468	$	1,408
Class S Shares	$	406	$	1,230
Class I Shares	$	359	$	1,091
Class T Shares	$	381	$	1,158

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annualized portfolio turnover rate was 12% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities of Asian issuers (excluding Japanese issuers). An Asian issuer is generally considered to be any company that (i) is incorporated or has its principal business activities in an Asian country; (ii) is primarily listed on the trading market of an Asian country; or (iii) derives 50% or more of its revenue from, or has 50% or more of its assets in, one or more Asian countries. The Fund considers “Asian countries” to include, but not be limited to, Hong Kong, China, South Korea, Taiwan, Singapore, Malaysia, Thailand, Indonesia, Philippines, India, Vietnam, Pakistan, Russia, and Sri Lanka. Some of these countries may represent developing or emerging markets.

The Fund generally invests in equity securities, which consist primarily of common stocks, preferred stocks, depositary receipts, and convertible securities, but may also include other types of instruments, such as equity-linked securities and real estate investment trusts issued by Asian real estate companies. The Fund may invest in companies of any market capitalization. While the Fund intends to diversify its investments across a number of different countries, including emerging market countries, it may, under unusual circumstances, invest all or a significant portion of its assets in a single Asian country. To a more limited degree, the Fund may also invest in U.S. and foreign debt securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. The portfolio manager will also analyze each company from a macro perspective taking into consideration any important themes or issues that may impact the investment environment in certain regions or sectors and to estimate regional market risks.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. For purposes of meeting the 80% investment policy, the Fund may include derivatives that have characteristics similar to the Fund’s direct investments. The Fund has invested in and may continue to invest in derivatives, such as swaps, to gain access to foreign markets, in particular where direct investment may be restricted or unavailable. The Fund may also invest in derivative instruments (by taking long and/or short positions) for other purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

3 ï Janus Asia Equity Fund

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an Asian equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 59.4% of the Fund’s investments were in emerging markets.

Geographic Concentration Risk. Because the Fund intends to focus its investments in a particular geographic region, the Fund’s performance is expected to be closely tied to various factors such as social, financial, economic, and political conditions within that region or country. Specifically, the Fund’s investments in Asian issuers increase the Fund’s exposure to the risks associated with volatile securities markets, adverse exchange rates, social, political and regulatory developments, and economic environmental events (such as natural disasters) which may be particular to Asian countries. Events that negatively affect the fiscal stability of Asian countries may cause the value of the Fund’s shares to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than more geographically diverse funds. In addition, many of the economies of the Asian countries in which the Fund invests are interdependent, which may cause them to experience the impact of such events at the same time or may increase the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

(1)  Janus Capital has contractually agreed to waive the Fund’s total annual fund operating expenses (excluding any performance adjustments to management fees, the distribution and shareholder servicing fees – applicable to Class A Shares, Class C Shares, and Class S Shares; administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees); brokerage commissions; interest; dividends; taxes; acquired fund fees and expenses; and extraordinary expenses) to 1.25% until at least February 1, 2013. The contractual waiver may be terminated or modified prior to this date only at the discretion of the Board of Trustees.

EXAMPLE:

The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your

7 ï Janus Emerging Markets Fund

investment has a 5% return each year and that the Fund’s operating expenses without waivers remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If Shares are redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	974	$	1,782	$	2,603	$	4,711
Class C Shares	$	615	$	1,542	$	2,565	$	5,112
Class S Shares	$	468	$	1,408	$	2,354	$	4,748
Class I Shares	$	395	$	1,198	$	2,018	$	4,147
Class T Shares	$	416	$	1,258	$	2,115	$	4,322

If Shares are not redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	974	$	1,782	$	2,603	$	4,711
Class C Shares	$	515	$	1,542	$	2,565	$	5,112

Class T Shares	$	416	$	1,258	$	2,115	$	4,322

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annualized portfolio turnover rate was 211% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of issuers in emerging market countries. The Fund normally invests in securities of issuers that (i) are primarily listed on the trading market of an emerging market country; (ii) are incorporated or have their principal business activities in an emerging market country; or (iii) derive 50% or more of their revenues from, or have 50% or more of their assets in, an emerging market country. An emerging market country is any country that has been determined by an international organization, such as the World Bank, to have a low to middle income economy and/or any country that is not included in the Morgan Stanley Capital International World Index^sm, which measures the equity market performance of developed markets. The Fund generally invests in equity securities, which consist primarily of common stocks, preferred stocks and convertible securities, but may also invest in other types of instruments, such as equity-linked securities and exchange-traded funds. The Fund may invest in companies of any market capitalization. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.

Although the Fund intends to invest substantially all of its assets in several issuers located in emerging market countries, it may invest up to 20% of its net assets in securities of issuers located in the U.S. or other developed market issuers, and it may, under unusual circumstances, invest all or a significant portion of its assets in a single emerging market country. The Fund may also invest in domestic and foreign debt securities.

The portfolio managers apply a “bottom up” approach in choosing investments. In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. For purposes of meeting the 80% investment policy, the Fund may include derivatives that have characteristics similar to the Fund’s direct investments. The Fund has invested in and may continue to invest in derivatives, such as swaps, to gain access to foreign markets, in particular where direct investment may be restricted or unavailable. The Fund may also invest in derivative instruments (by taking long and/or short positions) for other purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the

8 ï Janus Emerging Markets Fund

Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, particularly emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio managers’ perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other

asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Exchange-Traded Funds Risk. The Fund may purchase shares of exchange-traded funds (“ETFs”) to gain exposure to a particular portion of the market. ETFs are pooled investment vehicles, which may be managed or unmanaged, that generally seek to track the performance of a specific index. ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. ETFs have certain inherent risks generally associated with investments in a portfolio of common stocks, including the risk that the general level of stock prices may decline, thereby adversely affecting the value of each unit of the ETF. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. The bar chart depicts the Fund’s performance during the period indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. The index is not actively managed and is not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687.

The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If Shares are redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	679	$	899	$	1,136	$	1,816

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of companies that the portfolio manager believes have a life science orientation. Generally speaking, the “life sciences” relate to maintaining or improving quality of life. So, for example, companies with a “life science orientation” include companies engaged in research, development, production, or distribution of products or services related to health and personal care, medicine, or pharmaceuticals. The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund normally invests in issuers from several different countries, which may include the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities. As a fundamental policy, the Fund normally invests at least 25% of its total assets in the “life sciences” sector, which may include companies in the following industry groups: health care; pharmaceuticals; agriculture; cosmetics/personal care; and biotechnology.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

14 ï Janus Global Life Sciences Fund

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 3.7% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Concentration Risk. The Fund focuses its investments in “life sciences” related industry groups. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009.

•  The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

(2)	Calculated assuming maximum permitted sales loads.
(3)	The one year return is calculated to include the contingent deferred sales charge.

After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 78% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. The Fund may invest in companies of any size located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. The Fund normally invests at least 40% of its net assets in securities of issuers or companies from different countries located throughout the world, excluding the United States. The Fund may have significant exposure to emerging markets. The Fund may also invest in foreign equity and debt securities.

Janus Capital’s equity research analysts (the “Research Team”) select investments for the Fund which represent their high-conviction investment ideas in all market capitalizations, styles, and geographies. The Research Team, comprised of sector specialists, conducts fundamental analysis with a focus on “bottom up” research, quantitative modeling, and valuation analysis. Using this research process, analysts rate their stocks based upon attractiveness. Analysts bring their high-conviction ideas to their respective sector teams. Sector teams compare the appreciation and risk potential of each of the team’s high-conviction ideas and construct a sector portfolio that is intended to maximize the best risk-reward opportunities.

Positions may be sold when, among other things, there is no longer high conviction in the return potential of the investment or if the risk characteristics have caused a re-evaluation of the opportunity. This may occur if the stock has appreciated and reflects the anticipated value, if another company represents a better risk-reward opportunity, or if the investment’s fundamental characteristics deteriorate. Securities may also be sold from the portfolio to rebalance sector weightings.

Janus Capital’s Director of Equity Research oversees the investment process and is responsible for the day-to-day management of the Fund. It is expected that the Fund will be broadly diversified among a variety of industry sectors. The Fund intends to be fully invested under normal circumstances. However, under unusual circumstances, if the Research Team does not have high conviction in enough investment opportunities, the Fund’s uninvested assets may be held in cash or similar instruments.

The Fund may invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions, or to hedge currency exposure relative to the Fund’s benchmark index) and to earn income and enhance returns. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by

fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 6.3% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the investment personnel’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities. The Fund compares and broadly matches its sector weights to those of a growth-based index. If growth stocks are out of favor, sectors that are larger in a growth index may underperform, leading to Fund underperformance relative to indices less biased toward growth stocks.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 138% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by normally investing primarily in a core group of 30-50 domestic and foreign common stocks selected for their growth potential and normally investing at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. The Fund may invest in companies of any size located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. The Fund may also invest in U.S. and foreign debt securities. The Fund may have significant exposure to emerging markets. As of September 30, 2011, the Fund held stocks of 38 companies. Of these holdings, 30 comprised approximately 86.59% of the Fund’s holdings.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions), including, but not limited to, put and call options, futures contracts, and forward currency contracts. The Fund may use derivatives for different purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, to adjust its currency exposure relative to its benchmark index, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund invests primarily in common stocks, which tend to be more volatile than many other investment choices.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could

26 ï Janus Global Select Fund

also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Nondiversification Risk. The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund’s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s net asset value and total return.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 18.3% of the Fund’s investments were in emerging markets.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral

27 ï Janus Global Select Fund

provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009.

•  The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.

•  The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, without the effect of any fee and expense limitations or waivers.

If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. The index is not actively managed and is not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687.

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of companies that the portfolio manager believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories:

•  companies that the portfolio manager believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and

•  companies that the portfolio manager believes rely extensively on technology in connection with their operations or services.

The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund normally invests in issuers from several different countries, which may include the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions), including, but not limited to, put and call options, futures contracts, and forward currency contracts to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a

32 ï Janus Global Technology Fund

market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 4.2% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Industry Risk. Although the Fund does not concentrate its investments in specific industries, it may invest in companies related in such a way that they react similarly to certain market pressures. As a result, the Fund’s returns may be considerably more volatile than the returns of a fund that does not invest in similarly related companies.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009.

•  The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class A Shares, Class C Shares, and Class S Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.

•  The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, without the effect of any fee and expense limitations or waivers.

If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, and Class I Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687.

After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in equity securities. The Fund normally invests in a core group of 60-100 equity securities of issuers from different countries located throughout the world, excluding the United States. The Fund may, under unusual circumstances, invest all of its assets in a single country. The Fund may invest in emerging markets but will normally limit such investments to 20% of its net assets, measured at the time of purchase. The Fund may also invest in foreign debt securities.

The portfolio managers apply a “bottom up” approach in choosing investments. In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. The portfolio managers normally seek to limit any sector exposure and country exposure to plus or minus 10% of the respective weighting of the Fund’s primary benchmark index, currently the Morgan Stanley Capital International EAFE^® Index.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. As of September 30, 2011, approximately 12.0% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions.

In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class I Shares, Class A Shares, Class C Shares, Class S Shares, and Class R Shares of the Fund commenced operations on July 6, 2009, after the reorganization of each corresponding class of shares of Janus Adviser International Equity Fund (“JAD predecessor fund”) into each respective share class of the Fund.

If Class T Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class I Shares, Class A Shares, Class C Shares, Class S Shares, Class R Shares, and Class T Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

(2)	Calculated assuming maximum permitted sales loads.
(3)	The one year return is calculated to include the contingent deferred sales charge.

After-tax returns are calculated using distributions for the Fund’s Class I Shares for periods following July 6, 2009; and for the JAD predecessor fund’s Class I Shares for periods prior to July 6, 2009. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

After-tax returns are only shown for Class I Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class I Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services.

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If Shares are redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	675	$	887	$	1,116	$	1,773
Class C Shares	$	281	$	560	$	964	$	2,095
Class S Shares	$	121	$	378	$	654	$	1,443
Class I Shares	$	78	$	243	$	422	$	942

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 43% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of issuers from countries outside of the United States. The Fund normally invests in securities of issuers from several different countries, excluding the United States. Although the Fund typically invests 80% or more of its assets in issuers located outside the United States, it also may normally invest up to 20% of its assets, measured at the time of purchase, in U.S. issuers, and it may, under unusual circumstances, invest all or substantially all of its assets in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and

44 ï Janus Overseas Fund

standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 31.1% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009.

•  The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.

•  The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, without the effect of any fee and expense limitations or waivers.

If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687.

These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. Each share class has different expenses, but represents an investment in the same Fund. For Class A Shares, you may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Janus mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial professional and in the “Purchases” section on page 80 of the Fund’s Prospectus and in the “Purchases” section on page 90 of the Fund’s Statement of Additional Information.

Maximum Sales Charge (load) Imposed on Purchases (as a percentage of offering price)	5.75%	None	None	None	None	None
Maximum Deferred Sales Charge (load) (as a percentage of the lower of original purchase price or redemption proceeds)	None	1.00%	None	None	None	None
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)	None	None	2.00%	2.00%	2.00%	2.00%

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

If Shares are redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	680	$	902	$	1,141	$	1,827
Class C Shares	$	287	$	579	$	995	$	2,159
Class S Shares	$	124	$	387	$	670	$	1,477
Class I Shares	$	79	$	246	$	428	$	954
Class R Shares	$	150	$	465	$	803	$	1,757
Class T Shares	$	99	$	309	$	536	$	1,190

If Shares are not redeemed:	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	680	$	902	$	1,141	$	1,827
Class C Shares	$	187	$	579	$	995	$	2,159
Class S Shares	$	124	$	387	$	670	$	1,477

Class T Shares	$	99	$	309	$	536	$	1,190

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 94% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing primarily in equity securities, which include, but are not limited to, common stocks, preferred stocks, and depositary receipts of companies of any size located throughout the world. The Fund normally invests in issuers from several different countries, including the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in foreign equity and debt securities.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may invest a significant portion of its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions) including, but not limited to, put and call options, swaps, and forward currency contracts to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund, and to earn income and enhance returns. The Fund may also invest in derivative instruments for other purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions). For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

50 ï Janus Worldwide Fund

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 6.2% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009.

•  The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.

•  The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.

•  The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, without the effect of any fee and expense limitations or waivers.

If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/advisor/mutual-funds or by calling 1-877-335-2687.

For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.

TAX INFORMATION

The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Funds

FEES AND EXPENSES

Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on net assets as of the fiscal year ended September 30, 2011.

•  “Shareholder Fees” are fees paid directly from your investment and may include sales loads or redemption fees. If you sell Class S Shares, Class I Shares, Class R Shares, or Class T Shares of a Fund that you have held for 90 days or less, you may pay a redemption fee. The redemption fee is being eliminated, therefore, no sale or exchange of Class S Shares, Class I Shares, Class R Shares, or Class T Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

•  “Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.

•  The “Management Fee” is the investment advisory fee rate paid by each Fund to Janus Capital. Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Research Fund, Janus International Equity Fund, Janus Overseas Fund, and Janus Worldwide Fund each pay an investment advisory fee rate that adjusts up or down by a variable of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This fee rate, prior to any performance adjustment, is 0.92% for Janus Asia Equity Fund, 1.00% for Janus Emerging Markets Fund, 0.64% for each of Janus Global Research Fund and Janus Overseas Fund, 0.68% for Janus International Equity Fund, and 0.60% for Janus Worldwide Fund. Any such adjustment to this base fee rate commenced January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will commence August 2012 for Janus Asia Equity Fund and may increase or decrease the Management Fee. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).

•  “Distribution/Service (12b-1) Fees.” Because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.

•  A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example in each Fund Summary.

•  A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in the Shareholder’s Guide.

•  “Other Expenses”

○	for Class A Shares, Class C Shares, and Class I Shares, may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds.
○	for Class S Shares, Class R Shares, and Class T Shares, include an administrative services fee of 0.25% of the average daily net assets of each class to compensate Janus Services LLC (“Janus Services”), the Funds’ transfer agent, for providing, or arranging for the provision of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels.
○	for all classes, may include “Short Sale Dividend Expenses.” These expenses include dividends or interest on short sales, which are paid to the lender of borrowed securities, and stock loan fees, which are paid to the prime broker. Such expenses will vary depending on the short sale arrangement, whether the securities a Fund sells short pay dividends or interest, and the amount of such dividends or interest. While “Short Sale Dividend Expenses” include interest and dividends paid out on short positions and may include stock loan fees, they do not take into account the interest credit a Fund earns on cash proceeds of short sales which serve as collateral for short positions. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01%.

55 ï Janus Investment Fund

 ○  for all classes, may include reimbursement to Janus Services of its out-of-pocket costs for serving as transfer agent and providing servicing to shareholders.

•  “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01% and are included in the Fund’s “Other Expenses.”

•  Janus Capital has contractually agreed to waive certain Funds’ “Total Annual Fund Operating Expenses” to certain limits until at least February 1, 2013. The expense limits are described in the “Management Expenses” section of this Prospectus. Because a fee waiver will have a positive effect upon a fund’s performance, a fund that pays a performance-based investment advisory fee may experience a performance adjustment that is considered favorable to Janus Capital as a result of a fee waiver that is in place during the period when the performance adjustment applies.

•  All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

ADDITIONAL INVESTMENT STRATEGIES AND GENERAL PORTFOLIO POLICIES

The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to a Fund’s objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.

Unless otherwise stated, the following additional investment strategies and general policies apply to each Fund and provide further information including, but not limited to, the types of securities a Fund may invest in when implementing its investment objective. For some Funds, these strategies and policies may be part of a principal strategy. For other Funds, these strategies and policies may be utilized to a lesser extent. Except for the Funds’ policies with respect to investments in illiquid securities and borrowing, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities.

Cash Position

The Funds may not always stay fully invested. For example, when the portfolio managers and/or investment personnel believe that market conditions are unfavorable for investing, or when they are otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. In other words, cash or similar investments generally are a residual – they represent the assets that remain after a Fund has committed available assets to desirable investment opportunities. Partly because the portfolio managers and/or investment personnel act independently of each other, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.

In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment objective. As a result, the Fund may not achieve its investment objective.

56 ï Janus Investment Fund

Common Stock

Unless its investment objective or policies prescribe otherwise, each of the Funds may invest substantially all of its assets in common stocks. The portfolio managers and/or investment personnel generally take a “bottom up” approach to selecting companies in which to invest. This means that they seek to identify individual companies with earnings growth potential that may not be recognized by the market at large. Securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. There are no limitations on the countries in which the Funds may invest, and the Funds may at times have significant exposure in emerging markets. The portfolio managers and/or investment personnel may sell a holding if, among other things, the security reaches the portfolio managers’ and/or investment personnel’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if the portfolio managers and/or investment personnel find a better investment opportunity. The portfolio managers and/or investment personnel may also sell a Fund holding to meet redemptions.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures, and options. Each Fund intends to enter into financial transactions with counterparties that Janus Capital believes to be creditworthy at the time of the transaction. There is always the risk that Janus Capital’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Emerging Markets

Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International Emerging Markets Index^sm. Janus International Equity Fund will normally limit its investments in emerging market countries to 20% of its net assets. A summary of each Fund’s investments by country is contained in the Funds’ shareholder reports and in the Funds’ Form N-Q reports, which are filed with the Securities and Exchange Commission.

High-Yield/High-Risk Bonds

A high-yield/high-risk bond (also called a “junk” bond) is a bond rated below investment grade by major rating agencies (i.e., BB+ or lower by Standard & Poor’s Ratings Service (“Standard & Poor’s”) and Fitch, Inc. (“Fitch”), or Ba or lower by Moody’s Investors Service, Inc. (“Moody’s”)) or is an unrated bond of similar quality. It presents greater risk of default (the failure to make timely interest and principal payments) than higher quality bonds. To the extent the Funds invest in high-yield/high-risk bonds, under normal circumstances, each Fund, with the exception of Janus Asia Equity Fund, Janus Emerging Markets Fund, and Janus International Equity Fund, will limit its investments in high-yield/high-risk bonds to 35% or less of its net assets. Each of Janus Asia Equity Fund, Janus Emerging Markets Fund, and Janus International Equity Fund will limit its investments in such bonds to 20% or less of its net assets.

Illiquid Investments

Although the Funds intend to invest in liquid securities, each Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold to the U.S. public because of Securities and Exchange Commission regulations (these are known as “restricted securities”). Under procedures adopted by the Funds’ Trustees, certain restricted securities that are determined to be liquid will not be counted toward this 15% limit.

57 ï Janus Investment Fund

Nondiversification

Diversification is a way to reduce risk by investing in a broad range of stocks or other securities. Janus Global Select Fund is classified as “nondiversified.” A fund that is classified as “nondiversified” has the ability to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” This gives a fund which is classified as nondiversified more flexibility to focus its investments in companies that the portfolio manager has identified as the most attractive for the investment objective and strategy of the fund. However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of the fund.

Portfolio Turnover

In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund, the nature of a Fund’s investments, and the investment style of the portfolio manager and/or investment personnel. Changes are normally made in a Fund’s portfolio whenever the portfolio manager and/or investment personnel believe such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions.

Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.

Securities Lending

A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis. Each Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles. It is also possible that, due to a decline in the value of a cash management vehicle, the Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund. Janus Capital intends to manage the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

Short Sales

Certain Funds may engage in short sales. No more than 10% of a Fund’s net assets may be invested in short positions (through short sales of stocks, structured products, futures, swaps, and uncovered written calls). The Funds may engage in short sales “against the box” and options for hedging purposes that are not subject to this 10% limit. A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs at a time that other short sellers of the same security also want to close out their positions, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a

58 ï Janus Investment Fund

Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a Fund that does not engage in short sales and may negatively affect the Fund’s performance.

A Fund may also enter into short positions through derivative instruments such as options contracts, futures contracts, and swap agreements which may expose the Fund to similar risks. To the extent that the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Due to certain foreign countries’ restrictions, a Fund will not be able to engage in short sales in certain foreign countries where it may maintain long positions. As a result, a Fund’s ability to fully implement a short selling strategy that could otherwise help the Fund pursue its investment goals may be limited.

Although Janus Capital believes that its rigorous “bottom up” approach will be effective in selecting short positions, there is no assurance that Janus Capital will be successful in applying this approach when engaging in short sales.

Special Situations

The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of a Fund’s portfolio managers and/or investment personnel, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.

Swap Agreements

Certain Funds may utilize swap agreements as a means to gain exposure to certain common stocks and/or to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, equity, interest rate, and total return swaps are described in the “Glossary of Investment Terms.”

Other Types of Investments

Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies, as described in the “Glossary of Investment Terms.” These securities and strategies are not principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:

•  debt securities (such as bonds, notes, and debentures)

•  exchange-traded funds

•  indexed/structured securities (such as mortgage- and asset-backed securities)

•  various derivative transactions (which could comprise a significant percentage of a fund’s portfolio) including, but not limited to, options, futures, forwards, swap agreements (such as equity, interest rate, credit default, and total return swaps),

59 ï Janus Investment Fund

participatory notes, structured notes, and other types of derivatives individually or in combination for hedging purposes or for nonhedging purposes such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses; such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs

•  securities purchased on a when-issued, delayed delivery, or forward commitment basis

RISKS OF THE FUNDS

The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. To varying degrees, the Funds may invest in stocks, bonds, alternative strategy investments, and money market instruments or cash/cash equivalents. The following information is designed to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.

Concentration Risk. Janus Global Life Sciences Fund focuses its investments in “life sciences” related industry groups. Because of this, companies in its portfolio may share common characteristics and react similarly to market developments. For example, many companies with a life science orientation are highly regulated and may be dependent upon certain types of technology. As a result, changes in government funding or subsidies, new or anticipated legislative changes, or technological advances could affect the value of such companies and, therefore, the Fund’s net asset value. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.

Emerging Markets Risk. Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International Emerging Markets Index^sm. For Janus Emerging Markets Fund, such countries include any country that has been determined by an international organization, such as the World Bank, to have a low to middle income economy and/or any country that is not included in the Morgan Stanley Capital International World Index^sm, which measures the equity market performance of developed markets. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The price of investments in emerging markets can experience sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments. The securities markets of many of the countries in which a Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers

60 ï Janus Investment Fund

in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. Some of the risks of investing directly in foreign and emerging market securities may be reduced when a Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks.

Foreign Exposure Risks. Each Fund will invest in foreign debt and equity securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Investments in foreign securities, including securities of foreign and emerging markets governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:

•  Currency Risk. As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.

•  Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in emerging markets which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominately based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

•  Regulatory Risk. There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.

•  Foreign Market Risk. Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.

•  Geographic Investment Risk. To the extent that a Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, or regulatory events in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.

•  Transaction Costs. Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Geographic Concentration Risk. Because Janus Asia Equity Fund intends to focus its investments in a particular geographic region, the Fund’s performance is expected to be closely tied to various factors such as the social, financial, economic, and political conditions within that region or country. Specifically, the Fund’s investments in Asian issuers increase the Fund’s exposure to various risks including, but not limited to, risks associated with volatile securities markets, currency fluctuations,

61 ï Janus Investment Fund

social, political, and regulatory developments, economic environmental events (such as natural disasters), and changes in tax or economic policies, each of which, among others, may be particular to Asian countries or the region.

Because of the Fund’s investment focus on Asian issuers, its investments will be more sensitive to social, financial, economic, political, and regulatory developments affecting the fiscal stability of a particular country and/or the broader region. Events that negatively affect the fiscal stability of a particular country and/or the broader region may cause the value of the Fund’s holdings to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than a fund that is more geographically diverse in its investments.

The Asian region within which the Fund will focus its investments comprises countries in various stages of economic and political development. As a result, some countries may have relatively unstable governments or may experience adverse conditions such as overextension of credit, currency devaluations and restrictions, less efficient markets, rising unemployment, high inflation, underdeveloped financial services sectors, heavy reliance on international trade, prolonged economic recessions, and political instability, including military disruption, which could result in significant downturns and volatility in the economies of Asian countries, and therefore, have an adverse effect on the value of the Fund’s portfolio. Certain Asian countries may be vulnerable to trade barriers and other protectionist measures. Some countries have restricted the flow of money in and out of the country. Further, if Asian securities fall out of favor, it may cause the Fund to underperform funds that do not focus their investments in a single region of the world.

It is also possible that from time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to social, financial, economic, political, and regulatory developments. The economies of the Asian countries in which the Fund invests may be interdependent, which could increase the possibility that conditions in one country will adversely impact the issuers of securities in a different country or region, or that the impact of such conditions will be experienced at the same time by the region as a whole. Likewise, the economies of the Asian region may also be dependent on the economies of other countries, such as the United States and Europe, and events in these economies could negatively impact the economies of the Asian region.

The trading volume on some Asian stock exchanges tends to be much lower than in the United States, and Asian securities of some companies are less liquid and more volatile than similar United States securities, which could lead to a significant possibility of loss to the Fund. In addition, brokerage commissions on regional stock exchanges are fixed and are generally higher than the negotiated commissions in the United States.

High-Yield/High-Risk Bond Risk. High-yield/high-risk bonds (or “junk” bonds) are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s, Fitch, and Moody’s or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield/high-risk bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.

Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.

Industry Risk. Industry risk is the possibility that a group of related securities will decline in price due to industry-specific developments. Companies in the same or similar industries may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry increase that Fund’s exposure to industry risk. In the life sciences, for example, many companies are subject to government regulation and approval of their products and services, which may affect their price or availability. In addition, the products and services offered by these companies may quickly become obsolete in the face of scientific or technological developments. The economic outlook of such companies may fluctuate dramatically due to changes in regulatory or competitive environments. Similarly, in technology-related industries, competitive pressures may have a significant effect on the performance of companies in which a Fund may invest. In addition, technology and technology-related companies often progress at an accelerated rate, and these companies may be subject to short product cycles and aggressive pricing, which may increase their volatility.

Janus Global Life Sciences Fund invests in a concentrated portfolio, which may result in greater exposure to related industries. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

62 ï Janus Investment Fund

Management Risk. The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies employed for the Funds may fail to produce the intended results. A Fund may underperform its benchmark index or other mutual funds with similar investment objectives.

Because the Funds may invest substantially all of their assets in common stocks, the main risk is the risk that the value of the stocks they hold might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, a Fund’s share price may also decrease.

The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return swaps), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that a portfolio manager’s and/or investment personnel’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk.

A Fund’s performance may also be significantly affected, positively or negatively, by a portfolio manager’s and/or investment personnel’s use of certain types of investments, such as foreign (non-U.S.) securities, non-investment grade bonds (“junk bonds”), initial public offerings (“IPOs”), or securities of companies with relatively small market capitalizations. Note that a portfolio manager’s and/or investment personnel’s use of IPOs and other types of investments may have a magnified performance impact on a fund with a small asset base and the fund may not experience similar performance as its assets grow.

Market Risk. The value of a Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ and/or investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money.

It is also important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in net asset value, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude the Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) in July 2010 which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity

63 ï Janus Investment Fund

(or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

Nondiversification Risk. Janus Global Select Fund is classified as nondiversified under the Investment Company Act of 1940, as amended, and may hold a greater percentage of its assets in a smaller number of issuers. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s net asset value and total return. Being nondiversified may also make a Fund more susceptible to financial, economic, political, or other developments that may impact a security. Although the Fund may satisfy the requirements for a diversified fund, and has from time to time operated as diversified, the Fund’s nondiversified classification gives the Fund’s portfolio manager more flexibility to hold larger positions in a smaller number of securities than a fund that is classified as diversified. The Fund’s policy of concentrating its portfolio in a smaller number of holdings could result in more volatility in the Fund’s performance and share price.

Real Estate Risk. A Fund may be affected by risks associated with investments in real estate-related securities. The value of securities of issuers in the real estate and real estate-related industries, including real estate investment trusts, is sensitive to changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, supply and demand, and the management skill and creditworthiness of the issuer. These factors may impact a Fund’s investments in foreign real estate markets differently than U.S. real estate markets.

Small- and Mid-Sized Companies Risk. A Fund’s investments in securities issued by small- and mid-sized companies, which tend to be smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, while small- and mid-sized companies may realize more substantial growth than larger or more established issuers, they may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger companies, which could have a significant adverse effect on a Fund’s returns, especially as market conditions change.

Sovereign Debt Risk. Investments in foreign government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. A Fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the Fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.

Management of the Funds

INVESTMENT ADVISER

Janus Capital Management LLC, 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. Janus Capital is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments for all the Funds except Janus Asia Equity Fund. Janus Singapore is responsible for the day-to-day management of the investment portfolio of Janus Asia Equity Fund subject to the general oversight of Janus Capital. Janus Capital also provides certain administration and other services and is responsible for other business affairs of each Fund.

Janus Capital (together with its predecessors) has served as investment adviser to Janus mutual funds since 1970 and currently serves as investment adviser to all of the Janus funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.

Janus Capital furnishes certain administration, compliance, and accounting services for the Funds and is reimbursed by the Funds for certain of its costs in providing those services (to the extent Janus Capital seeks reimbursement and such costs are not otherwise waived). In addition, employees of Janus Capital and/or its affiliates may serve as officers of the Trust. Janus Capital provides office space for the Funds. Some expenses related to compensation payable to the Janus funds’ Chief Compliance Officer and compliance staff are shared with the Janus funds. The Funds also pay for salaries, fees, and expenses of certain Janus Capital employees and Fund officers, with respect to certain specified administration functions they perform on behalf of the Janus funds. The Janus funds pay these costs based on out-of-pocket expenses incurred by Janus Capital, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services Janus Capital provides to the Funds.

MANAGEMENT EXPENSES

Each Fund pays Janus Capital an investment advisory fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, any other transfer agent and custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay. Janus Capital pays Janus Singapore a subadvisory fee from its investment advisory fee for managing Janus Asia Equity Fund.

The following tables reflect each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate), as well as the actual investment advisory fee rate paid by each Fund to Janus Capital (gross and net of fee waivers, if applicable). The investment advisory fee rate is aggregated to include all investment advisory fees paid by a Fund.

Fixed-Rate Investment Advisory Fee

The Funds reflected below pay an investment advisory fee at a fixed rate based on each Fund’s average daily net assets.

Performance-Based Investment Advisory Fee

Janus Global Research Fund, Janus Worldwide Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Emerging Markets Fund, and Janus Asia Equity Fund each pay an investment advisory fee rate that may adjust up or down based on each Fund’s performance relative to the cumulative investment record of its benchmark index over the performance measurement period as reflected in the table below. Any adjustment to the investment advisory fee rate was effective January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will be effective August 2012 for Janus Asia Equity Fund. Until such time, only the base fee rate shown belowapplied. The third column shows the performance hurdle for outperformance or underperformance during the measurement period relative to each Fund’s respective benchmark index. The fourth column shows the performance adjusted investment advisory fee rate, which is equal to the Fund’s base fee rate plus or minus the performance adjustment over the period without any fee waivers. The fifth column shows the actual investment advisory fee rate, which is equal to the Fund’s base fee rate plus or minus the performance adjustment over the period and includes any applicable fee waiver. This fifth column shows the actual amount of the investment advisory fee rate paid by each Fund as of the end of the fiscal year.

As an example, if a Fund outperformed its benchmark index over the performance measurement period by its performance hurdle rate (listed in the table below), the advisory fee would increase by 0.15% (assuming constant assets). Conversely, if a Fund underperformed its benchmark index over the performance measurement period by its performance hurdle rate (listed in the table below), the advisory fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the performance hurdle rate may result in positive or negative incremental adjustments to the advisory fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the SAI.

Application of the expense waivers and their effect on annual fund operating expenses is reflected, when applicable, in the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus, and additional information is included under “Expense Limitations” below. The waivers and any applicable performance adjustments are not reflected in the base fee rates shown.

(3)	Any applicable Performance Adjustment began January 1, 2012 for the Fund.
(4)	For the fiscal year ended September 30, 2011, the Fund did not pay Janus Capital any investment advisory fees (net of fee waivers) because the Fund’s fee waiver exceeded the investment advisory fee.
(5)	Any applicable Performance Adjustment will begin August 1, 2012 for the Fund.

For Janus Global Research Fund, Janus Worldwide Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Emerging Markets Fund, and Janus Asia Equity Fund, the investment advisory fee rate is determined by calculating a base fee (shown in the previous table) and applying a performance adjustment (described in further detail below). The performance

66 ï Janus Investment Fund

adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index as shown below:

Fund Name	Benchmark Index
Janus Global Research Fund	MSCI World Growth Index
Janus Worldwide Fund	MSCI World Indexsm
Janus International Equity Fund	MSCI EAFE® Index
Janus Overseas Fund	MSCI All Country World ex-U.S. Indexsm
Janus Emerging Markets Fund	MSCI Emerging Markets Indexsm
Janus Asia Equity Fund	MSCI All Country Asia ex-Japan Index

The calculation of the performance adjustment applies as follows:

Investment Advisory Fee = Base Fee Rate +/– Performance Adjustment

The investment advisory fee rate paid to Janus Capital by each Fund in the table above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period generally is the previous 36 months, although no Performance Adjustment is made until a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund). When a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund), but less than 36 months, the performance measurement period is equal to the time that has elapsed since the performance-based fee structure took effect. As noted above, any applicable Performance Adjustment began January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will begin August 2012 for Janus Asia Equity Fund.

No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. For performance measurement periods prior to July 6, 2009, certain Funds calculated their Performance Adjustment by comparing the performance of Class T Shares (formerly named Class J Shares) against the investment record of its benchmark index. For periods beginning July 6, 2009, the investment performance of a Fund’s load-waived Class A Shares for the performance measurement period is used to calculate the

67 ï Janus Investment Fund

Performance Adjustment. Because the Performance Adjustment is based on a rolling 36-month performance measurement period, calculations based solely on the performance of a Fund’s load-waived Class A Shares will not be fully implemented for 36 months after July 6, 2009. Until that time, the Fund’s performance will be compared to a blended investment performance record that includes the Fund’s Class T Shares (formerly named Class J Shares) performance (the prior share class used for performance calculations) for the portion of the performance measurement period prior to July 6, 2009, and the Fund’s load-waived Class A Shares for the remainder of the period.

After Janus Capital determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares, or Class T Shares (formerly named Class J Shares) as the case may be, against the cumulative investment record of that Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements and subadvisory agreements (as applicable) is included in the Funds’ annual or semiannual report to shareholders. You can request the Funds’ annual or semiannual reports (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus representative at 1-877-335-2687. The reports are also available, free of charge, at janus.com/info.

Expense Limitations

Janus Capital has contractually agreed to waive the advisory fee payable by each Fund listed below in an amount equal to the amount, if any, that the Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding any performance adjustments to management fees, the distribution and shareholder servicing fees (applicable to Class A Shares, Class C Shares, Class S Shares, and Class R Shares), administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, exceed the annual rate shown below. For information about how the expense limit affects the total expenses of each Fund, see the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. Janus Capital has agreed to continue each waiver until at least February 1, 2013.

Fund Name	Expense Limit Percentage (%)
Janus Asia Equity Fund(1)	1.25
Janus Emerging Markets Fund(1)	1.25
Janus Global Research Fund(1)	1.00
Janus Global Select Fund	0.90
Janus International Equity Fund(1)	1.25
Janus Overseas Fund(1)	0.92
Janus Worldwide Fund(1)	1.00

(1)  The Fund pays an investment advisory fee rate that may adjust up or down based on the Fund’s performance relative to its benchmark index during a measurement period. Because a fee waiver will have a positive effect upon the Fund’s performance, a fee waiver that is in place during the period when the performance adjustment applies may affect the performance adjustment in a way that is favorable to Janus Capital.

Conflicts of Interest

Janus Capital and Janus Singapore each manage many funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus funds’ cash, may give rise to

70 ï Janus Investment Fund

conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, Janus Capital is the adviser to the Janus “funds of funds,” which are funds that invest primarily in other mutual funds managed by Janus Capital. Because Janus Capital is the adviser to the Janus “funds of funds” and the Funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus “fund of funds” among such Funds. To the extent that a Fund is an underlying fund in a Janus “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so. Such transactions could accelerate the realization of taxable income if sales of securities resulted in gains and could also increase a fund’s transaction costs. Large redemptions by a Janus “fund of funds” may cause a fund’s expense ratio to increase due to a resulting smaller asset base. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.

Other information

CLOSED FUND POLICIES

A Fund may limit sales of its Shares to new investors if Janus Capital and the Trustees believe continued sales may adversely affect the Fund’s ability to achieve its investment objective. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. Additional information regarding general policies and exceptions can be found in the closed funds’ prospectuses.

LIQUIDATION/REORGANIZATION OF A FUND

It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust and in accordance with any applicable regulations and laws, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.

DISTRIBUTION OF THE FUNDS

The Funds are distributed by Janus Distributors LLC (“Janus Distributors”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes

DISTRIBUTIONS

To avoid taxation of the Funds, the Internal Revenue Code requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A Fund’s income from certain dividends, interest, and any net realized short-term capital gains are paid to shareholders as ordinary income dividends. Certain dividend income may be reported to shareholders as “qualified dividend income,” which is generally subject to reduced rates of taxation. Net realized long-term capital gains, if any, are paid to shareholders as capital gains distributions, regardless of how long Shares of the Fund have been held. Distributions are made at the class level, so they may vary from class to class within a single Fund.

Distribution Schedule

Dividends from net investment income and distributions of capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.

How Distributions Affect a Fund’s NAV

Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.

“Buying a Dividend”

If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-deferred account, dividends paid to you would be included in your gross income for tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.

For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary, or a Janus representative (1-800-333-1181) if you hold Class I Shares directly with Janus. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-deferred plan or account.

TAXES

As with any investment, you should consider the tax consequences of investing in the Funds. Any time you sell or exchange shares of a fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction; whether the gain or loss is long-term or short-term depends on how long you owned the shares. Any tax liabilities generated by your transactions are your responsibility.

The following discussion does not apply to qualified tax-deferred accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser if you have any questions. Additionally, state or local taxes may apply to your investment, depending upon the laws of your state of residence.

Taxes on Distributions

Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. When gains from the sale of a security held by a Fund are paid to shareholders, the rate at which the gain will be taxed to shareholders depends on the length of time the Fund held the security. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local

taxes. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Generally, account tax information will be made available to shareholders on or before January 31st of each year. Information regarding distributions may also be reported to the Internal Revenue Service.

Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan.

Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 591/2, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.

The Funds may be required to withhold U.S. federal income tax on all distributions and redemptions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the Internal Revenue Service that they are subject to backup withholding. The current backup withholding rate is applied.

When shareholders sell Fund shares from a taxable account, they will typically receive information on their tax forms that calculates their gain or loss using the average cost method. This information currently is not reported to the IRS, and shareholders still have the option of calculating gains or losses using an alternative IRS permitted method. In accordance with legislation passed by Congress in 2008, however, your intermediary (or the Fund, if you hold Class I Shares directly with Janus) will begin reporting cost basis information to the IRS for shares purchased on or after January 1, 2012 and sold thereafter. Your intermediary (or the Fund, if you hold Class I Shares directly with Janus) will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method, unless you hold Class I Shares directly with Janus in which case the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the new cost basis reporting laws apply to you and your investments.

Taxation of the Funds

Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders as a foreign tax credit. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible. Certain transactions or strategies utilized by a Fund may generate nonqualified income that can impact an investor’s taxes.

The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distributions each year of all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income taxes twice. Funds that invest in partnerships may be subject to state tax liabilities.

Shareholder’s guide

The Funds offer multiple classes of shares in order to meet the needs of various types of investors.

Class A Shares and Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares may be offered without an initial sales charge through certain retirement platforms and through certain financial intermediary platforms, including but not limited to, fee-based broker-dealers or financial advisors, primarily on their wrap account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the wrap account. Class A Shares may pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. Class C Shares may pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class A Shares and Class C Shares may pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of their clients.

Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with Janus Capital or its affiliates to offer the Shares on their supermarket platforms. Class S Shares may pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of their clients.

Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares may pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of their clients. Class I Shares are also available to certain direct institutional investors including, but not limited to, corporations, certain retirement plans, public plans and foundations/endowments.

Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms. Class R Shares may pay up to 0.50% of net assets to financial intermediaries for the provision of distribution services and, to a certain extent, shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of the plan or plan participants.

Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with Janus Capital or its affiliates to offer the Shares on their supermarket platforms. Class T Shares may pay up to 0.25% of net assets to financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of their clients.

The Shares are not offered directly to individual investors. Consult with your financial intermediary representative for additional information on whether the Shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem Shares, contact your financial intermediary or refer to your plan documents. For Class I Shares held directly with Janus, please contact a Janus representative at 1-800-333-1181.

With certain limited exceptions, the Funds are available only to U.S. citizens or residents, and employees of Janus Capital or its affiliates.

PRICING OF FUND SHARES

The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the regular trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the NAV may be calculated earlier if trading on the NYSE is restricted, or as permitted by the Securities and Exchange Commission (“SEC”). Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.

The price you pay for purchases of Shares is the public offering price, which is the NAV next determined after your request is received in good order by a Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell Shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares. In order to receive a day’s price, your order must be received in good order by a Fund or its agents by the close of the regular trading session of the NYSE.

Securities held by the Funds are generally valued at market value. Certain short-term instruments maturing within 60 days or less are valued at amortized cost, which approximates market value. If a market quotation for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security (except for short-term instruments maturing within 60 days or less) will be determined in good faith under policies and procedures established by and under the supervision of the Funds’ Trustees. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. While fair value pricing may be more commonly used with foreign equity securities, it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Funds may use systematic fair valuation models provided by independent pricing services to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE.

Due to the subjective nature of fair value pricing, a Fund’s value for a particular security may be different from the last quoted market price. Fair value pricing may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in that Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of that Fund, which negatively impacts long-term shareholders. The Funds’ fair value pricing and excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.

The value of the securities of other open-end funds held by a Fund, if any, will be calculated using the NAV of such open-end funds, and the prospectuses for such open-end funds explain the circumstances under which they use fair value pricing and the effects of using fair value pricing.

All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Funds under the arrangements made between your financial intermediary or plan sponsor and its customers. The Funds are not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.

CHOOSING A SHARE CLASS

Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class R Shares, and Class T Shares are offered by this Prospectus. The Funds offer multiple classes of shares in order to meet the needs of various types of investors. For more information about these classes of Shares and whether or not you are eligible to purchase these Shares, please call 1-877-335-2687.

Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. When choosing a share class, you should consider:

•  how much you plan to invest;

•  how long you expect to own the shares;

•  the expenses paid by each class; and

DISTRIBUTION, SERVICING, AND ADMINISTRATIVE FEES

Distribution and Shareholder Servicing Plans

Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended, for Class A Shares, Class S Shares, and Class R Shares (each a “Plan”) and Class C Shares (the “Class C Plan”), each Fund pays Janus Distributors, the Trust’s distributor, a fee for the sale and distribution and/or shareholder servicing of the Shares based on the average daily net assets of each, at the following annual rates:

Class	12b-1 Fee for the Funds
Class A Shares		0.25%
Class C Shares		1.00%	(1)
Class S Shares		0.25%
Class R Shares		0.50%

(1)  Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.

Under the terms of each Plan, the Trust is authorized to make payments to Janus Distributors for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Funds.

78 ï Janus Investment Fund

Janus Distributors is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although Janus Distributors may, pursuant to a written agreement between Janus Distributors and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.

Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. Janus Distributors is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.

Because 12b-1 fees are paid out of a Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.

Administrative Fees

Class A Shares, Class C Shares, and Class I Shares

Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of the shareholders of the Funds. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with Janus. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. These administrative fees are paid by the Shares of the Funds to Janus Services, which uses such fees to reimburse intermediaries. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from Janus Services on behalf of the Funds converts from a networking structure to an omnibus account structure, or otherwise experiences increased costs, fees borne by the Shares may increase. Janus Services also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.

Class S Shares, Class R Shares, and Class T Shares

Janus Services receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares, Class R Shares, and Class T Shares of each Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with Janus. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. Janus Services expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Funds. Janus Services or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Funds.

PAYMENTS TO FINANCIAL INTERMEDIARIES BY JANUS CAPITAL OR ITS AFFILIATES

From its own assets, Janus Capital or its affiliates may pay selected brokerage firms or other financial intermediaries that sell Class A and Class C Shares of the Janus funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by Janus Capital, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Janus Capital and its affiliates consider a number of factors in making payments to financial intermediaries, including the distribution capabilities of the intermediary, the overall quality of

79 ï Janus Investment Fund

the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with Janus Capital’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Currently, these payments are limited to the top 100 distributors (measured by sales or expected sales of shares of the Janus funds). Broker-dealer firms currently receiving or expected to receive these fees are listed in the SAI.

In addition, for all share classes, Janus Capital, Janus Distributors, or their affiliates may pay fees, from their own assets, to brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via NSCC or other means) in connection with investments in the Janus funds. These fees are in addition to any fees that may be paid by the Janus funds for these types of services or other services.

Janus Capital or its affiliates may also share certain marketing expenses with intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Funds. Janus Capital or its affiliates may make payments to participate in intermediary marketing support programs which may provide Janus Capital or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus funds available to their customers.

The receipt of (or prospect of receiving) payments, reimbursements and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus funds’ shares over sales of another Janus funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach Janus Capital to request that Janus Capital make contributions to certain charitable organizations. In these cases, Janus Capital’s contribution may result in the financial intermediary, or its salespersons, recommending Janus funds over other mutual funds (or non-mutual fund investments).

The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.

PURCHASES

With the exception of Class I Shares, purchases of Shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Class I Shares may be purchased directly with the Funds in certain circumstances as described in the “Minimum Investment Requirements” section. Contact your financial intermediary, a Janus representative (1-800-333-1181) if you hold Class I Shares directly with Janus, or refer to your plan documents for information on how to invest in each Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, a Fund may permit an in-kind purchase of Shares at the discretion of Janus Capital. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Funds’ behalf. As discussed under “Payments

80 ï Janus Investment Fund

to financial intermediaries by Janus Capital or its affiliates,” Janus Capital and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Funds or that provide services in connection with investments in the Funds. You should consider such arrangements when evaluating any recommendation of the Funds.

Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”

In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. Until verification of your identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if they are unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.

In an effort to ensure compliance with this law, Janus’ Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

Minimum Investment Requirements

Class A Shares, Class C Shares, Class S Shares, and Class T Shares

The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-deferred accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, accounts held through certain wrap programs may not be subject to these minimums. Investors should refer to their intermediary for additional information.

The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares.

Class I Shares

The minimum investment is $1 million for institutional investors investing directly with Janus. Institutional investors generally may meet the minimum investment amount by aggregating multiple accounts within the same Fund. Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-deferred accounts or UGMA/UTMA accounts. Directors, officers, and employees of JCGI and its affiliates, as well as Trustees and officers of the Funds, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-deferred, tax-qualified and retirement plans, and accounts held through certain wrap programs. For additional information, contact your intermediary, plan sponsor, administrator, or a Janus representative, as applicable.

Class R Shares

Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for information regarding account minimums. For all other account types, the minimum investment is $2,500.

Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class T Shares

Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed. If you hold Class I Shares directly with a Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum. Please note that you may incur a tax liability as a result of a redemption.

81 ï Janus Investment Fund

Each Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.

Systematic Purchase Plan

You may arrange for periodic purchases by authorizing your financial intermediary (or a Janus representative, if you hold Class I Shares directly with a Fund) to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus representative for details.

Initial Sales Charge

Class A Shares

An initial sales charge may apply to your purchase of Class A Shares of the Funds based on the amount invested, as set forth in the table below. The sales charge is allocated between Janus Distributors and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

	Class A Shares			Class A Shares
	Sales Charge as a			Sales Charge as a

(1)	Offering Price includes the initial sales charge.
(2)	A contingent deferred sales charge of 1.00% may apply to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase.

For purchases of Class A Shares of $1,000,000 or greater, from its own assets, Janus Distributors may pay financial intermediaries commissions as follows:

•  1.00% on amounts from $1,000,000 to $4,000,000;

•  plus 0.50% on amounts greater than $4,000,000 to $10,000,000;

•  plus 0.25% on amounts over $10,000,000.

The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.

Qualifying for a Reduction or Waiver of Class A Shares Sales Charge

You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in these Funds or certain other Janus funds) with your current purchase of Class A Shares of the Funds and certain other Janus funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of Shares and purchases are described below. Contact your financial intermediary for more information.

Class A Shares of the Funds may be purchased without an initial sales charge by the following persons (and their spouses and children under 21 years of age): (i) registered representatives and other employees of intermediaries that have selling agreements with Janus Distributors to sell Class A Shares; (ii) directors, officers, and employees of JCGI and its affiliates; and

82 ï Janus Investment Fund

(iii) Trustees and officers of the Trust. In addition, the initial sales charge may be waived on purchases of Class A Shares through financial intermediaries that have entered into an agreement with Janus Distributors that allows the waiver of the sales charge.

In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Funds, their agents, or your financial intermediary may not retain this information.

Right of Accumulation. You may purchase Class A Shares of a Fund at a reduced sales charge determined by aggregating the dollar amount of the new purchase (measured by the offering price) and the total prior day’s net asset value (net amount invested) of all Class A Shares of the Fund and of certain other classes (Class A Shares and Class C Shares of the Trust) of Janus funds then held by you, or held in accounts identified under “Aggregating Accounts,” and applying the sales charge applicable to such aggregate amount. In order for your purchases and holdings to be aggregated for purposes of qualifying for such discount, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The right of accumulation is subject to modification or discontinuance at any time with respect to all shares purchased thereafter.

Letter of Intent. You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.

Aggregating Accounts. To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:

•  trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);

•  solely controlled business accounts; and

•  single participant retirement plans.

To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.

You may access information regarding sales loads, breakpoint discounts, and purchases of the Funds’ shares, free of charge, and in a clear and prominent format, on our website at janus.com/breakpoints, and by following the appropriate hyperlinks to the specific information.

Commission on Class C Shares

Janus Distributors may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to qualified plans or other financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.

EXCHANGES

Contact your financial intermediary, a Janus representative (1-800-333-1181) if you hold Class I Shares directly with a Fund, or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-deferred accounts).

•  You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan.

•  You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will only be processed in instances where there is no contingent deferred sales charge (“CDSC”) on the shares to be exchanged and no initial sales charge on the shares to be received. A Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.

•  You must meet the minimum investment amount for each fund.

•  The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate your exchange privilege if you make more than one round trip in the Fund in a 90-day period and may bar future purchases in the Fund or any of the other Janus funds. The Funds will work with intermediaries to apply the Funds’ exchange limit. However, the Funds may not always have the ability to monitor or enforce the trading activity in such accounts. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”

•  Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.

•  An exchange of Class S Shares, Class I Shares, Class R Shares, and Class T Shares from each Fund held for 90 days or less may be subject to the Fund’s redemption fee. For more information on redemption fees, including a discussion of the circumstances in which the redemption fee may not apply, refer to “Redemption Fee.” The redemption fee is being eliminated, therefore, no sale or exchange of Class S Shares, Class I Shares, Class R Shares, or Class T Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

Waiver of Sales Charges

Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to any initial sales charge of the Funds’ Class A Shares. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. Any CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the Shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.

REDEMPTIONS

Redemptions, like purchases, may generally be effected only through financial intermediaries, retirement platforms, and by certain direct institutional investors holding Class I Shares. Please contact your financial intermediary, a Janus representative (1-800-333-1181) if you hold Class I Shares directly with a Fund, or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.

Shares of each Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by a Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares or applicable redemption fee for Class S Shares, Class I Shares, Class R Shares, or Class T Shares, will normally be sent the business day following receipt of the redemption order.

Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except

84 ï Janus Investment Fund

for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.

Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed. If you hold Class I Shares directly with a Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum. Please note that you may incur a tax liability as a result of a redemption.

Large Shareholder Redemptions

Certain accounts or Janus affiliates may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these accounts of their holdings in a Fund may impact the Fund’s liquidity and NAV. These redemptions may also force a Fund to sell securities, which may negatively impact the Fund’s brokerage costs.

Redemptions In-Kind

Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash. If this occurs, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions.

While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs.

Systematic Withdrawal Plan

Class A Shares and Class C Shares

You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived through financial intermediaries that have entered into an agreement with Janus Distributors. The maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.

Class S Shares, Class I Shares, Class R Shares, and Class T Shares

You may arrange for periodic redemptions by authorizing your financial intermediary (or a Janus representative, if you hold Class I Shares directly with a Fund) to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus representative for details.

Contingent Deferred Sales Charge

Class A Shares and Class C Shares

A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.

CDSC Waivers

There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:

•  Upon the death or disability of an account owner;

85 ï Janus Investment Fund

•  Retirement plans and certain other accounts held through a financial intermediary that has entered into an agreement with Janus Distributors to waive CDSCs for such accounts;

•  Retirement plan shareholders taking required minimum distributions;

•  The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;

•  The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or

•  If a Fund chooses to liquidate or involuntarily redeem shares in your account.

To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.

Reinstatement Privilege

After you have redeemed Class A Shares, you have a one-time right to reinvest the proceeds into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.

REDEMPTION FEE – Eliminated effective April 2, 2012

Redemptions (and exchanges) of Class S Shares, Class I Shares, Class R Shares, or Class T Shares from a Fund held for 90 days or less may be subject to the Fund’s redemption fee. The redemption fee is 2.00% of a shareholder’s redemption proceeds. This fee is paid to the Fund rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Fund’s asset level and cash flow due to short-term money movements in and out of the Fund. The redemption fee is being eliminated, therefore, no sale or exchange of Class S Shares, Class I Shares, Class R Shares, or Class T Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

Certain intermediaries have agreed to charge the Funds’ redemption fee on their customers’ accounts. In this case, the amount of the fee and the holding period will generally be consistent with the Funds’. However, due to operational requirements, the intermediaries’ methods for tracking and calculating the fee may differ in some respects from the Funds’.

The redemption fee does not apply to certain types of accounts held through intermediaries, including: (i) certain employer-sponsored retirement plans; (ii) certain broker wrap fee and other fee-based programs; (iii) certain omnibus accounts where the omnibus account holder does not have the operational capability to impose a redemption fee on its underlying customers’ accounts; and (iv) certain intermediaries that do not have or report to the Funds sufficient information to impose a redemption fee on their customers’ accounts.

In addition, the redemption fee does not apply to: (i) premature distributions from retirement accounts that are exempt from IRS penalty due to the disability of or medical expenses incurred by the shareholder; (ii) required minimum distributions from retirement accounts; (iii) return of excess contributions in retirement accounts; (iv) redemptions resulting in the settlement of an estate due to the death of the shareholder; (v) redemptions through an automated systematic withdrawal or exchange plan; (vi) redemptions by participants of an employer-sponsored automatic enrollment 401(k) plan who properly elect a refund of contributions within 90 days of being automatically enrolled in such plan; (vii) involuntary redemptions imposed by Janus Capital; (viii) reinvested distributions (dividends and capital gains); and (ix) identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with existing target allocations. For same-fund share class exchanges, no redemption fee will be applied based on the exchange transaction. However, to the extent an intermediary is applying a redemption fee, the redemption fee will be imposed on a subsequent underlying shareholder-initiated sale of shares after the exchange. When cooperation from a financial intermediary is necessary to impose a redemption fee on its customers’ accounts, different or additional exemptions may be applied by the financial intermediary. Redemption fees may be waived under certain circumstances involving involuntary redemptions imposed by intermediaries. Contact your financial intermediary, a Janus representative (1-800-333-1181) if you hold Class I Shares directly with the Fund, or refer to your plan documents for more information on whether the redemption fee is applied to your shares.

In addition to the circumstances previously noted, each Fund reserves the right to waive the redemption fee at its discretion where it believes such waiver is in the best interests of the Fund, including but not limited to when it determines that

86 ï Janus Investment Fund

imposition of the redemption fee is not necessary to protect the Fund from the effects of short-term trading. In addition, each Fund reserves the right to modify or eliminate the redemption fee or waivers at any time. If there is a material change to the Funds’ redemption fee, the Funds will notify you at least 60 days prior to the effective date of the change.

EXCESSIVE TRADING

Excessive Trading Policies and Procedures

The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). Each Fund is intended for long-term investment purposes only, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus funds may be considered in enforcing these policies and procedures. As described below, however, the Funds may not be able to identify all instances of excessive trading or completely eliminate the possibility of excessive trading. In particular, it may be difficult to identify excessive trading in certain omnibus accounts and other accounts traded through intermediaries. By their nature, omnibus accounts, in which purchases and redemptions of the Funds’ shares by multiple investors are aggregated by the intermediary and presented to the Funds on a net basis, may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the elimination of excessive trading in the accounts impractical without the assistance of the intermediary.

The Funds attempt to deter excessive trading through at least the following methods:

•  exchange limitations as described under “Exchanges;”

•  trade monitoring; and

•  fair valuation of securities as described under “Pricing of Fund Shares.”

Generally, a purchase and redemption of Shares from the same Fund (i.e., “round trip”) within 90 calendar days may result in enforcement of a Fund’s excessive trading policies and procedures with respect to future purchase orders, provided that each Fund reserves the right to reject any purchase request as explained above.

The Funds monitor for patterns of shareholder frequent trading and may suspend or permanently terminate the exchange privilege of any investor who makes more than one round trip in a Fund over a 90-day period, and may bar future purchases into the Fund and any of the other Janus funds by such investor. The Funds’ excessive trading policies generally do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus funds by a Janus “fund of funds,” which is a fund that primarily invests in other Janus mutual funds; and (iii) identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with existing target allocations.

The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus fund, subject to 60 days’ notice to shareholders of that fund.

Investors who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. The Funds, however, cannot always identify or reasonably detect excessive trading that may be facilitated by financial intermediaries or made difficult to identify through the use of omnibus accounts by those intermediaries that transmit purchase, exchange, and redemption orders to the Funds, and thus the Funds may have difficulty curtailing such activity. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.

In an attempt to detect and deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.

87 ï Janus Investment Fund

Certain transactions in Fund shares, such as periodic rebalancing through intermediaries (no more frequently than every 60 days) or those which are made pursuant to systematic purchase, exchange, or redemption programs generally do not raise excessive trading concerns and normally do not require application of the Funds’ methods to detect and deter excessive trading.

Each Fund also reserves the right to reject any purchase request (including exchange purchases) by any investor or group of investors for any reason without prior notice, including, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund. For example, a Fund may refuse a purchase order if the Fund’s portfolio managers and/or investment personnel believe they would be unable to invest the money effectively in accordance with the Fund’s investment policies or the Fund would otherwise be adversely affected due to the size of the transaction, frequency of trading, or other factors.

The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.

Excessive Trading Risks

Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.

Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. Although the Funds have adopted fair valuation policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies, under such circumstances there is potential for short-term arbitrage trades to dilute the value of Fund shares.

Although the Funds take steps to detect and deter excessive trading pursuant to the policies and procedures described in this Prospectus and approved by the Trustees, there is no assurance that these policies and procedures will be effective in limiting excessive trading in all circumstances. For example, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.

Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.

AVAILABILITY OF PORTFOLIO HOLDINGS INFORMATION

The Mutual Fund Holdings Disclosure Policies and Procedures adopted by Janus Capital and all mutual funds managed within the Janus fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes policies and procedures with respect to disclosure of portfolio holdings.

•  Full Holdings. Each Fund is required to disclose its complete holdings in the quarterly holdings report on Form N-Q within 60 days of the end of each fiscal quarter, and in the annual report and semiannual report to Fund shareholders. These reports (i) are available on the SEC’s website at http://www.sec.gov; (ii) may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. (information on the Public Reference Room may be obtained by calling 1-800-SEC-0330); and (iii) are available without charge, upon request, by calling a Janus representative at 1-800-525-0020 (toll free). Portfolio holdings (excluding derivatives, short positions, and other investment positions), consisting of at least the names of the holdings, are generally available on a calendar quarter-end basis with a 30-day lag. Holdings are generally posted approximately two business days thereafter under Full Holdings for each Fund at janus.com/info.

88 ï Janus Investment Fund

Each Fund may provide, upon request, historical full holdings on a monthly basis for periods prior to the previous quarter-end subject to a written confidentiality agreement.

•  Top Holdings. Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag.

•  Other Information. Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top performance contributors/detractors (consisting of security names in alphabetical order), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag. Top performance contributors/detractors provided at calendar quarter-end may include the percentage of contribution/detraction to Fund performance.

Full portfolio holdings will remain available on the Janus websites at least until a Form N-CSR or Form N-Q is filed with the SEC for the period that includes the date as of which the website information is current. Funds disclose their short positions, if applicable, only to the extent required in regulatory reports. Janus Capital may exclude from publication all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by Janus Capital’s Chief Investment Officer(s) or their delegates. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.

SHAREHOLDER COMMUNICATIONS

Your financial intermediary or plan sponsor (or Janus, if you hold Class I Shares directly with a Fund) is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.

Your financial intermediary or plan sponsor (or Janus, if you hold Class I Shares directly with a Fund) is responsible for providing annual and semiannual reports, including the financial statements of the Funds that you have authorized for investment. These reports show each Fund’s investments and the market value of such investments, as well as other information about each Fund and its operations. Please contact your financial intermediary or plan sponsor (or Janus, if you hold Class I Shares directly with a Fund) to obtain these reports. The Funds’ fiscal year ends September 30.

Financial highlights

The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and the net expense ratio reflects expenses after any expense offset arrangement. Both expense ratios reflect expenses after waivers (reimbursements), if applicable. The information for the fiscal periods shown has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in the Annual Report, which is available upon request, and incorporated by reference into the SAI.

The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the Shares of the Funds (assuming reinvestment of all dividends and distributions).

Effective February 16, 2010, Class J Shares were renamed Class T Shares and the eligibility requirements changed so that only clients investing through a third-party intermediary may purchase Class T Shares.

Glossary of investment terms

This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.

EQUITY AND DEBT SECURITIES

Average-Weighted Effective Maturity is a measure of a bond’s maturity. The stated maturity of a bond is the date when the issuer must repay the bond’s entire principal value to an investor. Some types of bonds may also have an “effective maturity” that is shorter than the stated date due to prepayment or call provisions. Securities without prepayment or call provisions generally have an effective maturity equal to their stated maturity. Average-weighted effective maturity is calculated by averaging the effective maturity of bonds held by a Fund with each effective maturity “weighted” according to the percentage of net assets that it represents.

Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality. If a Fund purchases a participation interest, it may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender. Additional risks are involved in purchasing assignments. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. The Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of any collateral from a secured loan would satisfy a borrower’s obligations or that any collateral could be liquidated. A Fund may have difficulty trading assignments and participations to third parties or selling such securities in secondary markets, which in turn may affect the Fund’s NAV.

Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.

Certificates of Participation (“COPs”) are certificates representing an interest in a pool of securities. Holders are entitled to a proportionate interest in the underlying securities. Municipal lease obligations are often sold in the form of COPs. Refer to “Municipal lease obligations” below.

Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to investors seeking to invest idle cash. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended (the “1933 Act”).

Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.

Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.

Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.

Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).

Duration is the time it will take investors to recoup their investment in a bond. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity.

139 ï Janus Investment Fund

Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.

Exchange-traded funds (“ETFs”) are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Fixed-income securities are securities that pay a specified rate of return. The term generally includes short- and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.

High-yield/high-risk bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”

Industrial development bonds are revenue bonds that are issued by a public authority but which may be backed only by the credit and security of a private issuer and may involve greater credit risk. Refer to “Municipal securities” below.

Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis. These securities involve prepayment risk, which is the risk that the underlying mortgages or other debt may be refinanced or paid off prior to their maturities during periods of declining interest rates. In that case, a Fund may have to reinvest the proceeds from the securities at a lower rate. Potential market gains on a security subject to prepayment risk may be more limited than potential market gains on a comparable security that is not subject to prepayment risk.

Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts for property or equipment. Lease obligations may not be backed by the issuing municipality’s credit and may involve risks not normally associated with general obligation bonds and other revenue bonds. For example, their interest may become taxable if the lease is assigned and the holders may incur losses if the issuer does not appropriate funds for the lease payments on an annual basis, which may result in termination of the lease and possible default.

Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.

Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.

Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.

Pay-in-kind bonds are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.

Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.

140 ï Janus Investment Fund

Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans.

Rule 144A securities are securities that are not registered for sale to the general public under the 1933 Act, but that may be resold to certain institutional investors.

Standby commitment is a right to sell a specified underlying security or securities within a specified period of time and at an exercise price equal to the amortized cost of the underlying security or securities plus accrued interest, if any, at the time of exercise, that may be sold, transferred, or assigned only with the underlying security or securities. A standby commitment entitles the holder to receive same day settlement, and will be considered to be from the party to whom the investment company will look for payment of the exercise price.

Step coupon bonds are high-quality issues with above-market interest rates and a coupon that increases over the life of the bond. They may pay monthly, semiannual, or annual interest payments. On the date of each coupon payment, the issuer decides whether to call the bond at par, or whether to extend it until the next payment date at the new coupon rate.

Strip bonds are debt securities that are stripped of their interest (usually by a financial intermediary) after the securities are issued. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities of comparable maturity.

Tender option bonds are relatively long-term bonds that are coupled with the option to tender the securities to a bank, broker-dealer, or other financial institution at periodic intervals and receive the face value of the bond. This investment structure is commonly used as a means of enhancing a security’s liquidity.

U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.

Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate (the “underlying index”). The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.

Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.

Zero coupon bonds are debt securities that do not pay regular interest at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.

FUTURES, OPTIONS, AND OTHER DERIVATIVES

Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.

Derivatives are financial instruments whose performance is derived from the performance of another asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward contracts, swaps, and futures contracts.

Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component

141 ï Janus Investment Fund

may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form. An investment in equity-linked notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities, and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.

Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).

Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.

Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. A Fund may also buy options on futures contracts. An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.

Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments. A Fund bears the market risk of an investment in the underlying instruments, as well as the credit risk of the issuer.

Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).

Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.

Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.

Participatory notes are derivative securities which are linked to the performance of an underlying Indian security and which allow investors to gain market exposure to Indian securities without trading directly in the local Indian market.

Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period.

OTHER INVESTMENTS, STRATEGIES, AND/OR TECHNIQUES

Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles at the end of each day.

Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended (the “1940 Act”). Funds are classified as either “diversified” or “nondiversified.” To be classified as “diversified” under the 1940 Act, a fund

142 ï Janus Investment Fund

may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as “nondiversified” under the 1940 Act, on the other hand, has the flexibility to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.

Industry concentration for purposes under the 1940 Act is the investment of 25% or more of a Fund’s total assets in an industry or group of industries.

Leverage is when a Fund increases its assets available for investment using borrowings or similar transactions. Because short sales involve borrowing securities and then selling them, a Fund’s short sales effectively leverage the Fund’s assets. The use of leverage may make any change in a Fund’s NAV even greater and thus result in increased volatility of returns. A Fund’s assets that are used as collateral to secure the short sales may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage also creates interest expense that may lower a Fund’s overall returns.

Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.

Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.

Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash. These securities involve the risk that the seller will fail to repurchase the security, as agreed. In that case, a Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.

Reverse repurchase agreements involve the sale of a security by a Fund to another party (generally a bank or dealer) in return for cash and an agreement by the Fund to buy the security back at a specified price and time. This technique will be used primarily to provide cash to satisfy unusually high redemption requests, or for other temporary or emergency purposes.

Short sales in which a Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain. For short sales, the Fund will incur a loss if the value of a security increases during this period because it will be paying more for the security than it has received from the purchaser in the short sale. If the price declines during this period, a Fund will realize a short-term capital gain. Although a Fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security.

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. A Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

Janus Asia Equity Fund

Ticker: JAQDX Class D Shares*

*  Class D Shares are closed to certain new investors.

INVESTMENT OBJECTIVE

Janus Asia Equity Fund seeks long-term growth of capital.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)	Class D
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)	2.00%
Effective April 2, 2012, the Fund will no longer assess a redemption fee on Shares, regardless of how long such Shares have been held.
ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)	Class D
Management Fees (may adjust up or down)	0.92%
Other Expenses(1)	2.99%
Total Annual Fund Operating Expenses(2)	3.91%
Fee Waiver(2)	2.38%
Net Annual Fund Operating Expenses After Fee Waiver(2)	1.53%

(1)

Since the Fund is new, Other Expenses are based on the estimated expenses that the Fund expects to incur in its initial fiscal period.

(2)

Janus Capital has contractually agreed to waive the Fund’s total annual fund operating expenses (excluding any performance adjustments to management fees, administrative services fees payable pursuant to the Transfer Agency Agreement, brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) to 1.25% until at least February 1, 2013. The contractual waiver may be terminated or modified prior to this date only at the discretion of the Board of Trustees.

EXAMPLE:

The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses without waivers remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years
Class D Shares	$	393	$	1,192

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annualized portfolio turnover rate was 12% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities of Asian issuers (excluding Japanese issuers). An Asian issuer is generally considered to be any company that (i) is incorporated or has its principal business activities in an Asian country; (ii) is primarily listed on the trading market of an Asian country; or (iii) derives 50% or more of its revenue from, or has 50% or more of its assets in, one or more Asian countries. The Fund considers “Asian countries” to include, but not be limited to, Hong Kong, China, South Korea, Taiwan,

2 ï Janus Asia Equity Fund

Singapore, Malaysia, Thailand, Indonesia, Philippines, India, Vietnam, Pakistan, Russia, and Sri Lanka. Some of these countries may represent developing or emerging markets.

The Fund generally invests in equity securities, which consist primarily of common stocks, preferred stocks, depositary receipts, and convertible securities, but may also include other types of instruments, such as equity-linked securities and real estate investment trusts issued by Asian real estate companies. The Fund may invest in companies of any market capitalization. While the Fund intends to diversify its investments across a number of different countries, including emerging market countries, it may, under unusual circumstances, invest all or a significant portion of its assets in a single Asian country. To a more limited degree, the Fund may also invest in U.S. and foreign debt securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. The portfolio manager will also analyze each company from a macro perspective taking into consideration any important themes or issues that may impact the investment environment in certain regions or sectors and to estimate regional market risks.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. For purposes of meeting the 80% investment policy, the Fund may include derivatives that have characteristics similar to the Fund’s direct investments. The Fund has invested in and may continue to invest in derivatives, such as swaps, to gain access to foreign markets, in particular where direct investment may be restricted or unavailable. The Fund may also invest in derivative instruments (by taking long and/or short positions) for other purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an Asian equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies

3 ï Janus Asia Equity Fund

and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 59.4% of the Fund’s investments were in emerging markets.

Geographic Concentration Risk. Because the Fund intends to focus its investments in a particular geographic region, the Fund’s performance is expected to be closely tied to various factors such as social, financial, economic, and political conditions within that region or country. Specifically, the Fund’s investments in Asian issuers increase the Fund’s exposure to the risks associated with volatile securities markets, adverse exchange rates, social, political and regulatory developments, and economic environmental events (such as natural disasters) which may be particular to Asian countries. Events that negatively affect the fiscal stability of Asian countries may cause the value of the Fund’s shares to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than more geographically diverse funds. In addition, many of the economies of the Asian countries in which the Fund invests are interdependent, which may cause them to experience the impact of such events at the same time or may increase the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

EXAMPLE:

The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses without waivers remain the same.

	1 Year		3 Years		5 Years		10 Years
Class D Shares	$	445	$	1,343	$	2,251	$	4,566

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annualized portfolio turnover rate was 211% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of issuers in emerging market countries. The Fund normally invests in securities of issuers that (i) are primarily listed on the trading market of an emerging market country; (ii) are incorporated or have their principal business activities in an emerging market country; or (iii) derive 50% or more of their revenues from, or have 50% or more of their assets in, an emerging market country. An emerging market country is any country that has been determined by an international organization, such as the World Bank, to have a

low to middle income economy and/or any country that is not included in the Morgan Stanley Capital International World Index^sm, which measures the equity market performance of developed markets. The Fund generally invests in equity securities, which consist primarily of common stocks, preferred stocks and convertible securities, but may also invest in other types of instruments, such as equity-linked securities and exchange-traded funds. The Fund may invest in companies of any market capitalization. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.

Although the Fund intends to invest substantially all of its assets in several issuers located in emerging market countries, it may invest up to 20% of its net assets in securities of issuers located in the U.S. or other developed market issuers, and it may, under unusual circumstances, invest all or a significant portion of its assets in a single emerging market country. The Fund may also invest in domestic and foreign debt securities.

The portfolio managers apply a “bottom up” approach in choosing investments. In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. For purposes of meeting the 80% investment policy, the Fund may include derivatives that have characteristics similar to the Fund’s direct investments. The Fund has invested in and may continue to invest in derivatives, such as swaps, to gain access to foreign markets, in particular where direct investment may be restricted or unavailable. The Fund may also invest in derivative instruments (by taking long and/or short positions) for other purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, particularly emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which

7 ï Janus Emerging Markets Fund

could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio managers’ perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Exchange-Traded Funds Risk. The Fund may purchase shares of exchange-traded funds (“ETFs”) to gain exposure to a particular portion of the market. ETFs are pooled investment vehicles, which may be managed or unmanaged, that generally seek to track the performance of a specific index. ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. ETFs have certain inherent risks generally associated with investments in a portfolio of common stocks, including the risk that the general level of stock prices may decline, thereby adversely affecting the value of each unit of the ETF. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)			Class D
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)			2.00%
Effective April 2, 2012, the Fund will no longer assess a redemption fee on Shares, regardless of how long such Shares have been held.

Management Fees			0.64%
Other Expenses			0.27%
Short Sale Dividend Expenses	0.03	%
Remaining Other Expenses	0.24	%
Total Annual Fund Operating Expenses			0.91%

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class D Shares	$	93	$	290	$	504	$	1,120

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of companies that the portfolio manager believes have a life science orientation. Generally speaking, the “life sciences” relate to maintaining or improving quality of life. So, for example, companies with a “life science orientation” include companies engaged in research, development, production, or distribution of products or services related to health and personal care, medicine, or pharmaceuticals. The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund normally invests in issuers from several different countries, which may include the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities. As a fundamental policy, the Fund normally invests at least 25% of its total assets in the “life sciences” sector, which may include companies in the following industry groups: health care; pharmaceuticals; agriculture; cosmetics/personal care; and biotechnology.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 3.7% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Concentration Risk. The Fund focuses its investments in “life sciences” related industry groups. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 78% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. The Fund may invest in companies of any size located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. The Fund normally invests at least 40% of its net assets in securities of issuers or companies from different countries located throughout the world, excluding the United States. The Fund may have significant exposure to emerging markets. The Fund may also invest in foreign equity and debt securities.

Janus Capital’s equity research analysts (the “Research Team”) select investments for the Fund which represent their high-conviction investment ideas in all market capitalizations, styles, and geographies. The Research Team, comprised of sector specialists, conducts fundamental analysis with a focus on “bottom up” research, quantitative modeling, and valuation analysis. Using this research process, analysts rate their stocks based upon attractiveness. Analysts bring their high-conviction ideas to their respective sector teams. Sector teams compare the appreciation and risk potential of each of the team’s high-conviction ideas and construct a sector portfolio that is intended to maximize the best risk-reward opportunities.

16 ï Janus Global Research Fund

Positions may be sold when, among other things, there is no longer high conviction in the return potential of the investment or if the risk characteristics have caused a re-evaluation of the opportunity. This may occur if the stock has appreciated and reflects the anticipated value, if another company represents a better risk-reward opportunity, or if the investment’s fundamental characteristics deteriorate. Securities may also be sold from the portfolio to rebalance sector weightings.

Janus Capital’s Director of Equity Research oversees the investment process and is responsible for the day-to-day management of the Fund. It is expected that the Fund will be broadly diversified among a variety of industry sectors. The Fund intends to be fully invested under normal circumstances. However, under unusual circumstances, if the Research Team does not have high conviction in enough investment opportunities, the Fund’s uninvested assets may be held in cash or similar instruments.

The Fund may invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions, or to hedge currency exposure relative to the Fund’s benchmark index) and to earn income and enhance returns. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 6.3% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could

17 ï Janus Global Research Fund

also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the investment personnel’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities. The Fund compares and broadly matches its sector weights to those of a growth-based index. If growth stocks are out of favor, sectors that are larger in a growth index may underperform, leading to Fund underperformance relative to indices less biased toward growth stocks.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/allfunds or by calling 1-800-525-3713.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)			Class D
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)			2.00%
Effective April 2, 2012, the Fund will no longer assess a redemption fee on Shares, regardless of how long such Shares have been held.
ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)			Class D
Management Fees			0.64%
Other Expenses			0.22%
Short Sale Dividend Expenses	0.01	%
Remaining Other Expenses	0.21	%
Total Annual Fund Operating Expenses			0.86%

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class D Shares	$	88	$	274	$	477	$	1,061

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 138% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by normally investing primarily in a core group of 30-50 domestic and foreign common stocks selected for their growth potential and normally investing at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. The Fund may invest in companies of any size located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. The Fund may also invest in U.S. and foreign debt securities. The Fund may have significant exposure to emerging markets. As of September 30, 2011, the Fund held stocks of 38 companies. Of these holdings, 30 comprised approximately 86.59% of the Fund’s holdings.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

21 ï Janus Global Select Fund

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions), including, but not limited to, put and call options, futures contracts, and forward currency contracts. The Fund may use derivatives for different purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, to adjust its currency exposure relative to its benchmark index, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund invests primarily in common stocks, which tend to be more volatile than many other investment choices.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Nondiversification Risk. The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund’s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s net asset value and total return.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s

investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 18.3% of the Fund’s investments were in emerging markets.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of companies that the portfolio manager believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories:

•  companies that the portfolio manager believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and

•  companies that the portfolio manager believes rely extensively on technology in connection with their operations or services.

The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund normally invests in issuers from several different countries, which may include the United States.

26 ï Janus Global Technology Fund

The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may also invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions), including, but not limited to, put and call options, futures contracts, and forward currency contracts to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund, and to earn income and enhance returns.

For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 4.2% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

27 ï Janus Global Technology Fund

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Industry Risk. Although the Fund does not concentrate its investments in specific industries, it may invest in companies related in such a way that they react similarly to certain market pressures. As a result, the Fund’s returns may be considerably more volatile than the returns of a fund that does not invest in similarly related companies.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/allfunds or by calling 1-800-525-3713.

After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for the periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

INVESTMENT OBJECTIVE

Janus International Equity Fund seeks long-term growth of capital.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)	Class D
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)	2.00%
Effective April 2, 2012, the Fund will no longer assess a redemption fee on Shares, regardless of how long such Shares have been held.
ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)	Class D
Management Fees (may adjust up or down)	0.78%
Other Expenses	0.38%
Total Annual Fund Operating Expenses	1.16%

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class D Shares	$	118	$	368	$	638	$	1,409

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in equity securities. The Fund normally invests in a core group of 60-100 equity securities of issuers from different countries located throughout the world, excluding the United States. The Fund may, under unusual circumstances, invest all of its assets in a single country. The Fund may invest in emerging markets but will normally limit such investments to 20% of its net assets, measured at the time of purchase. The Fund may also invest in foreign debt securities.

The portfolio managers apply a “bottom up” approach in choosing investments. In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. The portfolio managers normally seek to limit any sector exposure and country exposure to plus or minus 10% of the respective weighting of the Fund’s primary benchmark index, currently the Morgan Stanley Capital International EAFE^® Index.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

31 ï Janus International Equity Fund

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. As of September 30, 2011, approximately 12.0% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio managers’ perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 43% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests, under normal circumstances, at least 80% of its net assets in securities of issuers from countries outside of the United States. The Fund normally invests in securities of issuers from several different countries, excluding the United States. Although the Fund typically invests 80% or more of its assets in issuers located outside the United States, it also may normally invest up to 20% of its assets, measured at the time of purchase, in U.S. issuers, and it may, under unusual circumstances, invest all or substantially all of its assets in a single country.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may invest its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions)

for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns. For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 31.1% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.

After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for the periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA.

INVESTMENT OBJECTIVE

Janus Worldwide Fund seeks long-term growth of capital.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)	Class D
Redemption fee on Shares held for 90 days or less (as a percentage of amount redeemed)	2.00%
Effective April 2, 2012, the Fund will no longer assess a redemption fee on Shares, regardless of how long such Shares have been held.
ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)	Class D
Management Fees (may adjust up or down)	0.66%
Other Expenses	0.21%
Total Annual Fund Operating Expenses	0.87%

EXAMPLE:

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class D Shares	$	89	$	278	$	482	$	1,073

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 94% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment objective by investing primarily in equity securities, which include, but are not limited to, common stocks, preferred stocks, and depositary receipts of companies of any size located throughout the world. The Fund normally invests in issuers from several different countries, including the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in foreign equity and debt securities.

The portfolio manager applies a “bottom up” approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies.

The Fund may invest a significant portion of its assets in derivatives, which are instruments that have a value derived from or directly linked to an underlying asset, such as equity securities, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund has invested in and may continue to invest in derivative instruments (by taking long and/or short positions) including, but not limited to, put and call options, swaps, and

40 ï Janus Worldwide Fund

forward currency contracts to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund, and to earn income and enhance returns. The Fund may also invest in derivative instruments for other purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions). For more information on the Fund’s use of derivatives, refer to the Fund’s shareholder reports and Form N-Q reports, which are filed with the Securities and Exchange Commission.

The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination.

PRINCIPAL INVESTMENT RISKS

The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.

Foreign Exposure Risk. The Fund normally has significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.

Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. As of September 30, 2011, approximately 6.2% of the Fund’s investments were in emerging markets.

Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

Growth Securities Risk. The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If the portfolio manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s return. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from the market as a whole and other types of securities.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore

41 ï Janus Worldwide Fund

involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Securities Lending Risk. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.

The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to broad-based securities market indices. The indices are not actively managed and are not available for direct investment. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janus.com/allfunds or by calling 1-800-525-3713.

Additional information about the Funds

FEES AND EXPENSES

Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on net assets as of the fiscal year ended September 30, 2011.

•  “Shareholder Fees” are fees paid directly from your investment and may include redemption fees or exchange fees. If you sell Shares of a Fund that you have held for 90 days or less, you may pay a redemption fee. The redemption fee is being eliminated, therefore, no sale or exchange of Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

•  “Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, accounting, and other shareholder services. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.

•  The “Management Fee” is the investment advisory fee rate paid by each Fund to Janus Capital. Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Research Fund, Janus International Equity Fund, Janus Overseas Fund, and Janus Worldwide Fund each pay an investment advisory fee rate that adjusts up or down by a variable of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This fee rate, prior to any performance adjustment, is 0.92% for Janus Asia Equity Fund, 1.00% for Janus Emerging Markets Fund, 0.64% for each of Janus Global Research Fund and Janus Overseas Fund, 0.68% for Janus International Equity Fund, and 0.60% for Janus Worldwide Fund. Any such adjustment to this base fee rate commenced January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will commence August 2012 for Janus Asia Equity Fund and may increase or decrease the Management Fee. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).

•  “Other Expenses”

○	include an administrative services fee of 0.12% of the average daily net assets of Class D Shares for shareholder services provided by Janus Services LLC (“Janus Services”), the Funds’ transfer agent.
○	may include “Short Sale Dividend Expenses.” These expenses include dividends or interest on short sales, which are paid to the lender of borrowed securities, and stock loan fees, which are paid to the prime broker. Such expenses will vary depending on the short sale arrangement, whether the securities a Fund sells short pay dividends or interest, and the amount of such dividends or interest. While “Short Sale Dividend Expenses” include interest and dividends paid out on short positions and may include stock loan fees, they do not take into account the interest credit a Fund earns on cash proceeds of short sales which serve as collateral for short positions. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01%.
○	may include reimbursement to Janus Services of its out-of-pocket costs for serving as transfer agent and providing servicing to shareholders.

•  “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01%. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01% and are included in the Fund’s “Other Expenses.”

•  Janus Capital has contractually agreed to waive certain Funds’ “Total Annual Fund Operating Expenses” to certain limits until at least February 1, 2013. The expense limits are described in the “Management Expenses” section of this Prospectus. Because a fee waiver will have a positive effect upon a fund’s performance, a fund that pays a performance-based investment advisory fee may experience a performance adjustment that is considered favorable to Janus Capital as a result of a fee waiver that is in place during the period when the performance adjustment applies.

45 ï Janus Investment Fund

•  All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

ADDITIONAL INVESTMENT STRATEGIES AND GENERAL PORTFOLIO POLICIES

The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to a Fund’s objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.

Unless otherwise stated, the following additional investment strategies and general policies apply to each Fund and provide further information including, but not limited to, the types of securities a Fund may invest in when implementing its investment objective. For some Funds, these strategies and policies may be part of a principal strategy. For other Funds, these strategies and policies may be utilized to a lesser extent. Except for the Funds’ policies with respect to investments in illiquid securities and borrowing, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities.

Cash Position

The Funds may not always stay fully invested. For example, when the portfolio managers and/or investment personnel believe that market conditions are unfavorable for investing, or when they are otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. In other words, cash or similar investments generally are a residual – they represent the assets that remain after a Fund has committed available assets to desirable investment opportunities. Partly because the portfolio managers and/or investment personnel act independently of each other, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.

In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment objective. As a result, the Fund may not achieve its investment objective.

Common Stock

Unless its investment objective or policies prescribe otherwise, each of the Funds may invest substantially all of its assets in common stocks. The portfolio managers and/or investment personnel generally take a “bottom up” approach to selecting companies in which to invest. This means that they seek to identify individual companies with earnings growth potential that may not be recognized by the market at large. Securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. There are no limitations on the countries in which the Funds may invest, and the Funds may at times have significant exposure in emerging markets. The portfolio managers and/or investment personnel may sell a holding if, among other things, the security reaches the portfolio managers’ and/or investment personnel’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if the portfolio managers and/or investment personnel find a better investment opportunity. The portfolio managers and/or investment personnel may also sell a Fund holding to meet redemptions.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e.,

46 ï Janus Investment Fund

financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures, and options. Each Fund intends to enter into financial transactions with counterparties that Janus Capital believes to be creditworthy at the time of the transaction. There is always the risk that Janus Capital’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Emerging Markets

Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International Emerging Markets Index^sm. Janus International Equity Fund will normally limit its investments in emerging market countries to 20% of its net assets. A summary of each Fund’s investments by country is contained in the Funds’ shareholder reports and in the Funds’ Form N-Q reports, which are filed with the Securities and Exchange Commission.

High-Yield/High-Risk Bonds

A high-yield/high-risk bond (also called a “junk” bond) is a bond rated below investment grade by major rating agencies (i.e., BB+ or lower by Standard & Poor’s Ratings Service (“Standard & Poor’s”) and Fitch, Inc. (“Fitch”), or Ba or lower by Moody’s Investors Service, Inc. (“Moody’s”)) or is an unrated bond of similar quality. It presents greater risk of default (the failure to make timely interest and principal payments) than higher quality bonds. To the extent the Funds invest in high-yield/high-risk bonds, under normal circumstances, each Fund, with the exception of Janus Asia Equity Fund, Janus Emerging Markets Fund, and Janus International Equity Fund, will limit its investments in high-yield/high-risk bonds to 35% or less of its net assets. Each of Janus Asia Equity Fund, Janus Emerging Markets Fund, and Janus International Equity Fund will limit its investments in such bonds to 20% or less of its net assets.

Illiquid Investments

Although the Funds intend to invest in liquid securities, each Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold to the U.S. public because of Securities and Exchange Commission regulations (these are known as “restricted securities”). Under procedures adopted by the Funds’ Trustees, certain restricted securities that are determined to be liquid will not be counted toward this 15% limit.

Nondiversification

Diversification is a way to reduce risk by investing in a broad range of stocks or other securities. Janus Global Select Fund is classified as “nondiversified.” A fund that is classified as “nondiversified” has the ability to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” This gives a fund which is classified as nondiversified more flexibility to focus its investments in companies that the portfolio manager has identified as the most attractive for the investment objective and strategy of the fund. However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of the fund.

Portfolio Turnover

In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund, the nature of a

47 ï Janus Investment Fund

Fund’s investments, and the investment style of the portfolio manager and/or investment personnel. Changes are normally made in a Fund’s portfolio whenever the portfolio manager and/or investment personnel believe such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions.

Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.

Securities Lending

A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis. Each Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles. It is also possible that, due to a decline in the value of a cash management vehicle, the Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund. Janus Capital intends to manage the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

Short Sales

Certain Funds may engage in short sales. No more than 10% of a Fund’s net assets may be invested in short positions (through short sales of stocks, structured products, futures, swaps, and uncovered written calls). The Funds may engage in short sales “against the box” and options for hedging purposes that are not subject to this 10% limit. A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs at a time that other short sellers of the same security also want to close out their positions, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a Fund that does not engage in short sales and may negatively affect the Fund’s performance.

A Fund may also enter into short positions through derivative instruments such as options contracts, futures contracts, and swap agreements which may expose the Fund to similar risks. To the extent that the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.

Due to certain foreign countries’ restrictions, a Fund will not be able to engage in short sales in certain foreign countries where it may maintain long positions. As a result, a Fund’s ability to fully implement a short selling strategy that could otherwise help the Fund pursue its investment goals may be limited.

Although Janus Capital believes that its rigorous “bottom up” approach will be effective in selecting short positions, there is no assurance that Janus Capital will be successful in applying this approach when engaging in short sales.

Special Situations

The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of a Fund’s portfolio managers and/or investment personnel, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.

Swap Agreements

Certain Funds may utilize swap agreements as a means to gain exposure to certain common stocks and/or to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, equity, interest rate, and total return swaps are described in the “Glossary of Investment Terms.”

Other Types of Investments

Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies, as described in the “Glossary of Investment Terms.” These securities and strategies are not principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:

•  debt securities (such as bonds, notes, and debentures)

•  exchange-traded funds

•  indexed/structured securities (such as mortgage- and asset-backed securities)

•  various derivative transactions (which could comprise a significant percentage of a fund’s portfolio) including, but not limited to, options, futures, forwards, swap agreements (such as equity, interest rate, credit default, and total return swaps), participatory notes, structured notes, and other types of derivatives individually or in combination for hedging purposes or for nonhedging purposes such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses; such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs

•  securities purchased on a when-issued, delayed delivery, or forward commitment basis

RISKS OF THE FUNDS

The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. To varying degrees, the Funds may invest in stocks, bonds, alternative strategy investments, and money market instruments or cash/cash equivalents. The following information is designed to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.

49 ï Janus Investment Fund

Concentration Risk. Janus Global Life Sciences Fund focuses its investments in “life sciences” related industry groups. Because of this, companies in its portfolio may share common characteristics and react similarly to market developments. For example, many companies with a life science orientation are highly regulated and may be dependent upon certain types of technology. As a result, changes in government funding or subsidies, new or anticipated legislative changes, or technological advances could affect the value of such companies and, therefore, the Fund’s net asset value. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.

Emerging Markets Risk. Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International Emerging Markets Index^sm. For Janus Emerging Markets Fund, such countries include any country that has been determined by an international organization, such as the World Bank, to have a low to middle income economy and/or any country that is not included in the Morgan Stanley Capital International World Index^sm, which measures the equity market performance of developed markets. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The price of investments in emerging markets can experience sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments. The securities markets of many of the countries in which a Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. Some of the risks of investing directly in foreign and emerging market securities may be reduced when a Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks.

Foreign Exposure Risks. Each Fund will invest in foreign debt and equity securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Investments in foreign securities, including securities of foreign and emerging markets governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:

•  Currency Risk. As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign

50 ï Janus Investment Fund

issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.

•  Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in emerging markets which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominately based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

•  Regulatory Risk. There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.

•  Foreign Market Risk. Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.

•  Geographic Investment Risk. To the extent that a Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, or regulatory events in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.

•  Transaction Costs. Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Geographic Concentration Risk. Because Janus Asia Equity Fund intends to focus its investments in a particular geographic region, the Fund’s performance is expected to be closely tied to various factors such as the social, financial, economic, and political conditions within that region or country. Specifically, the Fund’s investments in Asian issuers increase the Fund’s exposure to various risks including, but not limited to, risks associated with volatile securities markets, currency fluctuations, social, political, and regulatory developments, economic environmental events (such as natural disasters), and changes in tax or economic policies, each of which, among others, may be particular to Asian countries or the region.

Because of the Fund’s investment focus on Asian issuers, its investments will be more sensitive to social, financial, economic, political, and regulatory developments affecting the fiscal stability of a particular country and/or the broader region. Events that negatively affect the fiscal stability of a particular country and/or the broader region may cause the value of the Fund’s holdings to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than a fund that is more geographically diverse in its investments.

The Asian region within which the Fund will focus its investments comprises countries in various stages of economic and political development. As a result, some countries may have relatively unstable governments or may experience adverse conditions such as overextension of credit, currency devaluations and restrictions, less efficient markets, rising unemployment, high inflation, underdeveloped financial services sectors, heavy reliance on international trade, prolonged economic recessions, and political instability, including military disruption, which could result in significant downturns and volatility in the economies of Asian countries, and therefore, have an adverse effect on the value of the Fund’s portfolio. Certain Asian countries may be vulnerable to trade barriers and other protectionist measures. Some countries have restricted the flow of

51 ï Janus Investment Fund

money in and out of the country. Further, if Asian securities fall out of favor, it may cause the Fund to underperform funds that do not focus their investments in a single region of the world.

It is also possible that from time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to social, financial, economic, political, and regulatory developments. The economies of the Asian countries in which the Fund invests may be interdependent, which could increase the possibility that conditions in one country will adversely impact the issuers of securities in a different country or region, or that the impact of such conditions will be experienced at the same time by the region as a whole. Likewise, the economies of the Asian region may also be dependent on the economies of other countries, such as the United States and Europe, and events in these economies could negatively impact the economies of the Asian region.

The trading volume on some Asian stock exchanges tends to be much lower than in the United States, and Asian securities of some companies are less liquid and more volatile than similar United States securities, which could lead to a significant possibility of loss to the Fund. In addition, brokerage commissions on regional stock exchanges are fixed and are generally higher than the negotiated commissions in the United States.

High-Yield/High-Risk Bond Risk. High-yield/high-risk bonds (or “junk” bonds) are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s, Fitch, and Moody’s or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield/high-risk bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.

Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.

Industry Risk. Industry risk is the possibility that a group of related securities will decline in price due to industry-specific developments. Companies in the same or similar industries may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry increase that Fund’s exposure to industry risk. In the life sciences, for example, many companies are subject to government regulation and approval of their products and services, which may affect their price or availability. In addition, the products and services offered by these companies may quickly become obsolete in the face of scientific or technological developments. The economic outlook of such companies may fluctuate dramatically due to changes in regulatory or competitive environments. Similarly, in technology-related industries, competitive pressures may have a significant effect on the performance of companies in which a Fund may invest. In addition, technology and technology-related companies often progress at an accelerated rate, and these companies may be subject to short product cycles and aggressive pricing, which may increase their volatility.

Janus Global Life Sciences Fund invests in a concentrated portfolio, which may result in greater exposure to related industries. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Management Risk. The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies employed for the Funds may fail to produce the intended results. A Fund may underperform its benchmark index or other mutual funds with similar investment objectives.

Because the Funds may invest substantially all of their assets in common stocks, the main risk is the risk that the value of the stocks they hold might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, a Fund’s share price may also decrease.

The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return swaps), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that a portfolio manager’s and/or investment personnel’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk.

52 ï Janus Investment Fund

A Fund’s performance may also be significantly affected, positively or negatively, by a portfolio manager’s and/or investment personnel’s use of certain types of investments, such as foreign (non-U.S.) securities, non-investment grade bonds (“junk bonds”), initial public offerings (“IPOs”), or securities of companies with relatively small market capitalizations. Note that a portfolio manager’s and/or investment personnel’s use of IPOs and other types of investments may have a magnified performance impact on a fund with a small asset base and the fund may not experience similar performance as its assets grow.

Market Risk. The value of a Fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers’ and/or investment personnel’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money.

It is also important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in net asset value, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude the Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) in July 2010 which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity (or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

Nondiversification Risk. Janus Global Select Fund is classified as nondiversified under the Investment Company Act of 1940, as amended, and may hold a greater percentage of its assets in a smaller number of issuers. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s net asset value and total return. Being nondiversified may also make a Fund more susceptible to financial, economic, political, or other developments that may impact a security. Although the Fund may satisfy the requirements for a diversified fund, and has from time to time operated as diversified, the Fund’s nondiversified classification gives the Fund’s portfolio manager more flexibility to hold larger positions in a smaller number of securities than a fund that is classified as diversified. The Fund’s policy of concentrating its portfolio in a smaller number of holdings could result in more volatility in the Fund’s performance and share price.

Real Estate Risk. A Fund may be affected by risks associated with investments in real estate-related securities. The value of securities of issuers in the real estate and real estate-related industries, including real estate investment trusts, is sensitive to changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, supply and

53 ï Janus Investment Fund

demand, and the management skill and creditworthiness of the issuer. These factors may impact a Fund’s investments in foreign real estate markets differently than U.S. real estate markets.

Small- and Mid-Sized Companies Risk. A Fund’s investments in securities issued by small- and mid-sized companies, which tend to be smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, while small- and mid-sized companies may realize more substantial growth than larger or more established issuers, they may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger companies, which could have a significant adverse effect on a Fund’s returns, especially as market conditions change.

Sovereign Debt Risk. Investments in foreign government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. A Fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the Fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.

Management of the Funds

INVESTMENT ADVISER

Janus Capital Management LLC, 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. Janus Capital is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments for all the Funds except Janus Asia Equity Fund. Janus Singapore is responsible for the day-to-day management of the investment portfolio of Janus Asia Equity Fund subject to the general oversight of Janus Capital. Janus Capital also provides certain administration and other services and is responsible for other business affairs of each Fund.

Janus Capital (together with its predecessors) has served as investment adviser to Janus mutual funds since 1970 and currently serves as investment adviser to all of the Janus funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.

Janus Capital furnishes certain administration, compliance, and accounting services for the Funds and is reimbursed by the Funds for certain of its costs in providing those services (to the extent Janus Capital seeks reimbursement and such costs are not otherwise waived). In addition, employees of Janus Capital and/or its affiliates may serve as officers of the Trust. Janus Capital provides office space for the Funds. Some expenses related to compensation payable to the Janus funds’ Chief Compliance Officer and compliance staff are shared with the Janus funds. The Funds also pay for salaries, fees, and expenses of certain Janus Capital employees and Fund officers, with respect to certain specified administration functions they perform on behalf of the Janus funds. The Janus funds pay these costs based on out-of-pocket expenses incurred by Janus Capital, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services Janus Capital provides to the Funds.

MANAGEMENT EXPENSES

Each Fund pays Janus Capital an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, any other transfer agent and custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay. Janus Capital pays Janus Singapore a subadvisory fee from its investment advisory fee for managing Janus Asia Equity Fund.

The following tables reflect each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate), as well as the actual investment advisory fee rate paid by each Fund to Janus Capital (gross and net of fee waivers, if applicable). The investment advisory fee rate is aggregated to include all investment advisory fees paid by a Fund.

Fixed-Rate Investment Advisory Fee

The Funds reflected below pay an investment advisory fee at a fixed rate based on each Fund’s average daily net assets.

Performance-Based Investment Advisory Fee

Janus Global Research Fund, Janus Worldwide Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Emerging Markets Fund, and Janus Asia Equity Fund each pay an investment advisory fee rate that may adjust up or down based on each Fund’s performance relative to the cumulative investment record of its benchmark index over the performance

measurement period as reflected in the table below. Any adjustment to the investment advisory fee rate was effective January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will be effective August 2012 for Janus Asia Equity Fund. Until such time, only the base fee rate shown belowapplied. The third column shows the performance hurdle for outperformance or underperformance during the measurement period relative to each Fund’s respective benchmark index. The fourth column shows the performance adjusted investment advisory fee rate, which is equal to the Fund’s base fee rate plus or minus the performance adjustment over the period without any fee waivers. The fifth column shows the actual investment advisory fee rate, which is equal to the Fund’s base fee rate plus or minus the performance adjustment over the period and includes any applicable fee waiver. This fifth column shows the actual amount of the investment advisory fee rate paid by each Fund as of the end of the fiscal year.

As an example, if a Fund outperformed its benchmark index over the performance measurement period by its performance hurdle rate (listed in the table below), the advisory fee would increase by 0.15% (assuming constant assets). Conversely, if a Fund underperformed its benchmark index over the performance measurement period by its performance hurdle rate (listed in the table below), the advisory fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the performance hurdle rate may result in positive or negative incremental adjustments to the advisory fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the SAI.

Application of the expense waivers and their effect on annual fund operating expenses is reflected, when applicable, in the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus, and additional information is included under “Expense Limitations” below.

For Janus Global Research Fund, Janus Worldwide Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Emerging Markets Fund, and Janus Asia Equity Fund, the investment advisory fee rate is determined by calculating a base fee (shown in the previous table) and applying a performance adjustment (described in further detail below). The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index as shown below:

Fund Name	Benchmark Index
Janus Global Research Fund	MSCI World Growth Index

Janus International Equity Fund	MSCI EAFE® Index

56 ï Janus Investment Fund

The calculation of the performance adjustment applies as follows:

Investment Advisory Fee = Base Fee Rate +/– Performance Adjustment

The investment advisory fee rate paid to Janus Capital by each Fund in the table above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period generally is the previous 36 months, although no Performance Adjustment is made until a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund). When a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund), but less than 36 months, the performance measurement period is equal to the time that has elapsed since the performance-based fee structure took effect. As noted above, any applicable Performance Adjustment began January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will begin August 2012 for Janus Asia Equity Fund.

No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. For performance measurement periods prior to July 6, 2009, certain Funds calculated their Performance Adjustment by comparing the performance of Class T Shares (formerly named Class J Shares) against the investment record of its benchmark index. For periods beginning July 6, 2009, the investment performance of a Fund’s load-waived Class A Shares for the performance measurement period is used to calculate the Performance Adjustment. Because the Performance Adjustment is based on a rolling 36-month performance measurement period, calculations based solely on the performance of a Fund’s load-waived Class A Shares will not be fully implemented for 36 months after July 6, 2009. Until that time, the Fund’s performance will be compared to a blended investment performance record that includes the Fund’s Class T Shares (formerly named Class J Shares) performance (the prior share class used for performance calculations) for the portion of the performance measurement period prior to July 6, 2009, and the Fund’s load-waived Class A Shares for the remainder of the period.

After Janus Capital determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares, or Class T Shares (formerly named Class J Shares) as the case may be, against the cumulative investment record of that Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it depends

57 ï Janus Investment Fund

on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements and subadvisory agreements (as applicable) is included in the Funds’ annual or semiannual report to shareholders. You can request the Funds’ annual or semiannual reports (as they become available), free of charge, by contacting a Janus representative at 1-800-525-3713. The reports are also available, free of charge, at janus.com/reports.

Expense Limitations

Janus Capital has contractually agreed to waive the advisory fee payable by each Fund listed below in an amount equal to the amount, if any, that the Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding any performance adjustments to management fees, administrative services fees payable pursuant to the Transfer Agency Agreement, brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, exceed the annual rate shown below. For information about how the expense limit affects the total expenses of each Fund, see the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. Janus Capital has agreed to continue each waiver until at least February 1, 2013.

Fund Name	Expense Limit Percentage (%)
Janus Asia Equity Fund(1)	1.25
Janus Emerging Markets Fund(1)	1.25
Janus Global Research Fund(1)	1.00
Janus Global Select Fund	0.90

(1)  The Fund pays an investment advisory fee rate that may adjust up or down based on the Fund’s performance relative to its benchmark index during a measurement period. Because a fee waiver will have a positive effect upon the Fund’s performance, a fee waiver that is in place during the period when the performance adjustment applies may affect the performance adjustment in a way that is favorable to Janus Capital.

Conflicts of Interest

Janus Capital and Janus Singapore each manage many funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus funds’ cash, may give rise to

60 ï Janus Investment Fund

conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, Janus Capital is the adviser to the Janus “funds of funds,” which are funds that invest primarily in other mutual funds managed by Janus Capital. Because Janus Capital is the adviser to the Janus “funds of funds” and the Funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus “fund of funds” among such Funds. To the extent that a Fund is an underlying fund in a Janus “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so. Such transactions could accelerate the realization of taxable income if sales of securities resulted in gains and could also increase a fund’s transaction costs. Large redemptions by a Janus “fund of funds” may cause a fund’s expense ratio to increase due to a resulting smaller asset base. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.

Other information

CLOSED FUND POLICIES

A Fund may limit sales of its Shares to new investors if Janus Capital and the Trustees believe continued sales may adversely affect the Fund’s ability to achieve its investment objective. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. Additional information regarding general policies and exceptions can be found in the closed funds’ prospectuses.

LIQUIDATION/REORGANIZATION OF A FUND

It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust and in accordance with any applicable regulations and laws, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.

DISTRIBUTION OF THE FUNDS

The Funds are distributed by Janus Distributors LLC (“Janus Distributors”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes

DISTRIBUTIONS

To avoid taxation of the Funds, the Internal Revenue Code requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A Fund’s income from certain dividends, interest, and any net realized short-term capital gains are paid to shareholders as ordinary income dividends. Certain dividend income may be reported to shareholders as “qualified dividend income,” which is generally subject to reduced rates of taxation. Net realized long-term capital gains, if any, are paid to shareholders as capital gains distributions, regardless of how long Shares of the Fund have been held. Distributions are made at the class level, so they may vary from class to class within a single Fund.

Distribution Schedule

Dividends from net investment income and distributions of capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well.

How Distributions Affect a Fund’s NAV

Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.

“Buying a Dividend”

If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-deferred account, dividends paid to you would be included in your gross income for tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.

For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-deferred plan or account.

DISTRIBUTION OPTIONS

When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janus.com/individual, by calling a Janus representative, or by writing to the Funds at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Funds offer the following options:

Reinvestment Option. You may reinvest your income dividends and capital gains distributions in additional shares.

Cash Option. You may receive your income dividends and capital gains distributions in cash.

Reinvest and Cash Option. You may receive either your income dividends or capital gains distributions in cash and reinvest the other in additional shares.

Redirect Option. You may direct your dividends or capital gains distributions to purchase shares of another Janus fund.

The Funds reserve the right to reinvest undeliverable and uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Distributions.”

TAXES

As with any investment, you should consider the tax consequences of investing in the Funds. Any time you sell or exchange shares of a fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction; whether the gain or loss is long-term or short-term depends on how long you owned the shares. Any tax liabilities generated by your transactions are your responsibility.

The following discussion does not apply to qualified tax-deferred accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser if you have any questions. Additionally, state or local taxes may apply to your investment, depending upon the laws of your state of residence.

Taxes on Distributions

Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. When gains from the sale of a security held by a Fund are paid to shareholders, the rate at which the gain will be taxed to shareholders depends on the length of time the Fund held the security. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Generally, account tax information will be made available to shareholders on or before January 31st of each year. Information regarding distributions may also be reported to the Internal Revenue Service.

Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan.

Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 591/2, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.

The Funds may be required to withhold U.S. federal income tax on all distributions and redemptions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the Internal Revenue Service that they are subject to backup withholding. The current backup withholding rate is applied.

When shareholders sell Fund shares from a taxable account, they will typically receive information on their tax forms that calculates their gain or loss using the average cost method. This information currently is not reported to the IRS, and shareholders still have the option of calculating gains or losses using an alternative IRS permitted method. In accordance with legislation passed by Congress in 2008, however, each Fund will begin reporting cost basis information to the IRS for shares purchased on or after January 1, 2012 and sold thereafter. Each Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the new cost basis reporting laws apply to you and your investments.

Taxation of the Funds

Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders as a foreign tax credit. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible. Certain transactions or strategies utilized by a Fund may generate nonqualified income that can impact an investor’s taxes.

64 ï Janus Investment Fund

The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distributions each year of all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income taxes twice. Funds that invest in partnerships may be subject to state tax liabilities.

The Shares are available only to investors who hold accounts directly with the Janus funds, and to immediate family members or members of the same household of an eligible individual investor. Under certain limited circumstances, shareholders of other Janus share classes who no longer wish to hold shares through an intermediary may be eligible to purchase Class D Shares.

In addition, directors, officers, and employees of JCGI and its affiliates, as well as Trustees and officers of the Funds, may purchase Class D Shares. Under certain circumstances, where there has been a change in the form of ownership due to, for example, mandatory retirement distributions, legal proceedings, estate settlements, or the gifting of Shares, the recipient of Class D Shares may continue to purchase Class D Shares.

The Funds offer multiple classes of shares in order to meet the needs of various types of investors. You should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. If you would like additional information about the other available share classes, please call 1-800-525-3713.

MINIMUM INVESTMENTS*

To open a new regular Fund account	$	2,500
To open a new UGMA/UTMA account, Coverdell Education Savings Account, or a retirement Fund account
• without an automatic investment program	$	1,000
• with an automatic investment program of $100 per month	$	500
To add to any existing type of Fund account	$	100

*  The Funds reserve the right to change the amount of these minimums from time to time or to waive them in whole or in part. Participants in certain retirement plans, including but not limited to, Janus prototype Money Purchase Pension and Profit Sharing plans, SEP IRAs, SAR SEP IRAs, or outside qualified retirement plans, may not be subject to the stated minimums. Employees of Janus Capital, its wholly-owned subsidiaries, INTECH, and Perkins may open Fund accounts for $100.

Minimum Investment Requirements

Due to the proportionately higher costs of maintaining small accounts, the Funds reserve the right to deduct an annual $25 minimum balance fee per Fund account (paid to Janus Services) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You may receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.

TYPES OF ACCOUNT OWNERSHIP

Please refer to janus.com/individual or an account application for specific requirements to open and maintain an account.

Individual or Joint Ownership

Individual accounts are owned by one person. Joint accounts have two or more owners.

Trust

An established trust can open an account. The names of each trustee, the name of the trust, and the date of the trust agreement must be included on the application.

Business Accounts

Corporations and partnerships may also open an account. The application must be signed by an authorized officer of the corporation or a general partner of the partnership.

TAX-DEFERRED ACCOUNTS

Please refer to janus.com/individual or an account application for specific requirements to open and maintain an account. Certain tax-deferred accounts can only be opened and maintained via written request. Please contact a Janus representative for more information.

If you are eligible, you may set up one or more tax-deferred accounts. A tax-deferred account allows you to shelter your investment income and capital gains from current income taxes. A contribution to certain of these plans may also be tax deductible. The types of tax-deferred accounts that may be opened with Janus are described below. Investors should consult their tax adviser or legal counsel before selecting a tax-deferred account. You may initiate a rollover or a transfer of assets from certain tax-deferred accounts via janus.com/individual.

Investing for Your Retirement

Please visit janus.com/individual or call a Janus representative for more complete information regarding the different types of IRAs available. Distributions from these plans may be subject to income tax and generally to an additional tax if withdrawn prior to age 591/2 or used for a nonqualifying purpose.

Traditional and Roth IRAs

Both IRAs allow most individuals with earned income to contribute up to the lesser of $5,000 or 100% of compensation, with future years increased by cost-of-living adjustments. In addition, IRA holders age 50 or older may contribute $1,000 more than these limits.

67 ï Janus Investment Fund

Simplified Employee Pension (“SEP”) IRA

This plan allows small business owners (including sole proprietors) to make tax-deductible contributions for themselves and any eligible employee(s). A SEP requires an IRA (a “SEP-IRA”) to be set up for each SEP participant.

Profit Sharing or Money Purchase Pension Plans

These plans are open to corporations, partnerships, and small business owners (including sole proprietors) for the benefit of their employees and themselves. You may only open and maintain this type of account via written request. Please contact a Janus representative for more information.

ACCOUNTS FOR THE BENEFIT OF A CHILD

Custodial Accounts (UGMA or UTMA)

An UGMA/UTMA account is a custodial account managed for the benefit of a minor.

Coverdell Education Savings Account

This tax-deferred plan allows individuals, subject to certain income limitations, to contribute up to $2,000 annually on behalf of any child under the age of 18. Contributions are also allowed on behalf of children with special needs beyond age 18. Distributions are generally tax-free when used for qualified education expenses.

Please refer to the following for information regarding opening an account and conducting business with Janus. With certain limited exceptions, the Funds are available only to U.S. citizens or residents, and employees of Janus or its affiliates.

PRICING OF FUND SHARES

The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the regular trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the NAV may be calculated earlier if trading on the NYSE is restricted, or as permitted by the Securities and Exchange Commission (“SEC”). Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.

All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after your request is received in good order by a Fund or its agents.

Securities held by the Funds are generally valued at market value. Certain short-term instruments maturing within 60 days or less are valued at amortized cost, which approximates market value. If a market quotation for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security (except for short-term instruments maturing within 60 days or less) will be determined in good faith under policies and procedures established by and under the supervision of the Funds’ Trustees. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific

69 ï Janus Investment Fund

development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. While fair value pricing may be more commonly used with foreign equity securities, it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Funds may use systematic fair valuation models provided by independent pricing services to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE.

Due to the subjective nature of fair value pricing, a Fund’s value for a particular security may be different from the last quoted market price. Fair value pricing may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in that Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of that Fund, which negatively impacts long-term shareholders. The Funds’ fair value pricing and excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.

The value of the securities of other open-end funds held by a Fund, if any, will be calculated using the NAV of such open-end funds, and the prospectuses for such open-end funds explain the circumstances under which they use fair value pricing and the effects of using fair value pricing.

Policies in Relation to Transactions

All requests, including but not limited to, exchanges between a Fund and other Janus funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the regular trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus’ P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase.

ADMINISTRATIVE SERVICES FEES

The Funds pay an annual administrative services fee of 0.12% of net assets of Class D Shares. These administrative services fees are paid by Class D Shares of each Fund for shareholder services provided by Janus Services.

PAYMENTS TO FINANCIAL INTERMEDIARIES BY JANUS CAPITAL OR ITS AFFILIATES

With respect to other share classes not offered in this Prospectus, Janus Capital or its affiliates may pay, from their own assets, selected brokerage firms or other financial intermediaries that sell the Janus funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by Janus Capital, may be substantial, and may differ for different financial intermediaries. Janus Capital and its affiliates consider a number of factors in making payments to financial intermediaries.

In addition, with respect to other share classes not offered in this Prospectus, Janus Capital or its affiliates may pay fees, from their own assets, to brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via National Securities Clearing Corporation or other means) in connection with investments in the Janus funds. These fees are in addition to any fees that may be paid by the Janus funds for these types of services or other services.

70 ï Janus Investment Fund

Further, Janus Capital or its affiliates may also share certain marketing expenses with intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Funds. Janus Capital or its affiliates may make payments to participate in intermediary marketing support programs which may provide Janus Capital or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus funds available to their customers.

The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus funds’ shares over sales of another Janus funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach Janus Capital to request that Janus Capital make contributions to certain charitable organizations. In these cases, Janus Capital’s contribution may result in the financial intermediary, or its salespersons, recommending Janus funds over other mutual funds (or non-mutual fund investments).

The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you.

PAYING FOR SHARES

Please note the following when purchasing Shares:

•  Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.

•  All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted Canadian bank.

•  Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.

•  When purchasing Shares through the Automatic Investment Program, if no date or dollar amount is specified on your application, investments of $100 will be made on the 20th of each month. Your first automatic investment may take up to two weeks to establish. If the balance in the Janus fund account you are buying into falls to zero as the result of a redemption or exchange, your Automatic Investment Program will be discontinued.

•  We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Funds by submitting good funds via another method accepted by the Funds (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.

•  Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”

71 ï Janus Investment Fund

•  If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus to (i) buy shares of another Janus fund or (ii) sell shares of Janus Money Market Fund and return the proceeds (including any dividends earned) to you, Janus will treat your inaction as approval of the purchase of Janus Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”

•  For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.

•  If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and may be responsible for losses that may be incurred as a result of any decline in the value of the cancelled purchase.

In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), Janus is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. Until verification of your identity is made, Janus may temporarily limit additional share purchases. In addition, Janus may close an account if they are unable to verify a shareholder’s identity. Please contact a Janus representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.

In an effort to ensure compliance with this law, Janus’ Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

The Funds have also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Funds are required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.

EXCHANGES

Please note the following when exchanging shares:

•  An exchange represents the redemption (or sale) of shares from one Fund and the purchase of shares of another Fund, which may produce a taxable gain or loss in a non-retirement account.

•  You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust.

•  You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. A Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.

•  New regular Janus fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus fund account you are exchanging from is less than $2,500. (If your Janus fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)

72 ï Janus Investment Fund

•  UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus fund account you are exchanging from is less than the stated minimum, you must exchange the entire balance. (If your Janus fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)

•  New Janus fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)

•  Exchanges between existing Janus fund accounts must meet the $100 subsequent investment requirement.

•  For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.

•  The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate your exchange privilege if you make more than one round trip in the Fund in a 90-day period and may bar future purchases in the Fund or any of the other Janus funds. Different restrictions may apply if you invest through an intermediary. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”

•  Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.

•  An exchange of Shares from each Fund held for 90 days or less may be subject to the Fund’s redemption fee. For more information on redemption fees, including a discussion of the circumstances in which the redemption fee may not apply, refer to “Redemption Fee.” The redemption fee is being eliminated, therefore, no sale or exchange of Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

•  With certain limited exceptions, exchanges between Janus fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.

•  If the shares you are exchanging are held in certificate form, you must return the certificate to Janus prior to making any exchanges. Shares are no longer available in certificate form.

Note: For the fastest and easiest way to exchange shares, log on to janus.com/individual* 24 hours a day, 7 days a week.

*  Certain account types do not allow transactions via janus.com. For more information, access janus.com/individual or refer to this Shareholder’s Manual.

PAYMENT OF REDEMPTION PROCEEDS

By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.

•  Next Day Wire Transfer – Your redemption proceeds, less any applicable redemption fee, can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.

•  ACH (Automated Clearing House) Transfer – Your redemption proceeds, less any applicable redemption fee, can be electronically transferred to your predesignated bank account on or about the second bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.

By Check – Redemption proceeds, less any applicable redemption fee, will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.

73 ï Janus Investment Fund

By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.

Generally, orders to sell Shares may be initiated at any time at janus.com/individual, by telephone, or in writing. Certain tax-deferred accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Funds can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide alternate instructions, your proceeds will be invested in Shares of Janus Money Market Fund during the 15-day hold period.

Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.

Note: For the fastest and easiest way to redeem shares, log on to janus.com/individual* 24 hours a day, 7 days a week.

*  Certain account types do not allow transactions via janus.com. For more information, access janus.com/individual or refer to this Shareholder’s Manual.

Large Shareholder Redemptions

Certain accounts or Janus affiliates may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these accounts of their holdings in a Fund may impact the Fund’s liquidity and NAV. These redemptions may also force a Fund to sell securities, which may negatively impact the Fund’s brokerage costs.

Redemptions In-Kind

Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash. If this occurs, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions.

While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs.

REDEMPTION FEE – Eliminated effective April 2, 2012

Redemptions (and exchanges) of Shares from a Fund held for 90 days or less may be subject to the Fund’s redemption fee. The redemption fee is 2.00% of a shareholder’s redemption proceeds. This fee is paid to the Fund rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Fund’s asset level and cash flow due to short-term money movements in and out of the Fund. The redemption fee is being eliminated, therefore, no sale or exchange of Shares made on or after April 2, 2012 will be assessed a redemption fee, regardless of how long such Shares have been held.

Certain intermediaries have agreed to charge the Funds’ redemption fee on their customers’ accounts. In this case, the amount of the fee and the holding period will generally be consistent with the Funds’. However, due to operational requirements, the intermediaries’ methods for tracking and calculating the fee may differ in some respects from the Funds’.

The redemption fee does not apply to certain types of accounts held through intermediaries, including: (i) certain employer-sponsored retirement plans; (ii) certain broker wrap fee and other fee-based programs; (iii) certain omnibus accounts where the omnibus account holder does not have the operational capability to impose a redemption fee on its underlying customers’ accounts; and (iv) certain intermediaries that do not have or report to the Funds sufficient information to impose a redemption fee on their customers’ accounts.

In addition, the redemption fee does not apply to: (i) premature distributions from retirement accounts that are exempt from IRS penalty due to the disability of or medical expenses incurred by the shareholder; (ii) required minimum distributions from retirement accounts; (iii) return of excess contributions in retirement accounts; (iv) redemptions resulting in the settlement of an estate due to the death of the shareholder; (v) redemptions through an automated systematic withdrawal or exchange plan; (vi) redemptions by participants of an employer-sponsored automatic enrollment 401(k) plan who properly elect a refund of contributions within 90 days of being automatically enrolled in such plan; (vii) involuntary redemptions imposed by Janus Capital; (viii) reinvested distributions (dividends and capital gains); and (ix) identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with existing target allocations. For same-fund share class exchanges, no redemption fee will be applied based on the exchange transaction. However, the redemption fee will be imposed on a subsequent sale of shares after the exchange.

In addition to the circumstances previously noted, each Fund reserves the right to waive the redemption fee at its discretion where it believes such waiver is in the best interests of the Fund, including but not limited to when it determines that imposition of the redemption fee is not necessary to protect the Fund from the effects of short-term trading. In addition, each Fund reserves the right to modify or eliminate the redemption fee or waivers at any time. If there is a material change to the Funds’ redemption fee, the Funds will notify you at least 60 days prior to the effective date of the change.

WRITTEN INSTRUCTIONS

To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:

•  the name of the Janus fund(s) being redeemed or exchanged;

•  the account number(s);

•  the amount of money or number of shares being redeemed or exchanged;

•  the name(s) on the account;

•  the signature(s) of one or more registered account owners; and

•  your daytime telephone number.

SIGNATURE GUARANTEE

A signature guarantee for each registered account owner is required if any of the following is applicable:

•  You request a redemption by check above a certain dollar amount.

•  You would like a check made payable to anyone other than the shareholder(s) of record.

•  You would like a check mailed to an address that has been changed within 10 days of the redemption request.

•  You would like a check mailed to an address other than the address of record.

•  You would like your redemption proceeds sent to a bank account other than a bank account of record.

The Funds reserve the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.

A signature guarantee may be refused if any of the following is applicable:

•  It does not appear valid or in good form.

•  The transaction amount exceeds the surety bond limit of the signature guarantee.

•  The guarantee stamp has been reported as stolen, missing, or counterfeit.

How to Obtain a Signature Guarantee

A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust

75 ï Janus Investment Fund

companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if they have the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.

If you live outside the United States, a foreign bank properly authorized to do business in your country of residence or a U.S. consulate may be able to authenticate your signature.

EXCESSIVE TRADING

Excessive Trading Policies and Procedures

The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). Each Fund is intended for long-term investment purposes only, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus funds may be considered in enforcing these policies and procedures. Direct investors should be aware that the Funds are also available for purchase through third party intermediaries. As described below, the Funds may not be able to identify all instances of excessive trading or completely eliminate the possibility of excessive trading. In particular, it may be difficult to identify excessive trading in certain omnibus accounts and other accounts traded through intermediaries. By their nature, omnibus accounts, in which purchases and redemptions of the Funds’ shares by multiple investors are aggregated by the intermediary and presented to the Funds on a net basis, may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the elimination of excessive trading in the accounts impractical without the assistance of the intermediary.

The Funds attempt to deter excessive trading through at least the following methods:

•  exchange limitations as described under “Exchanges;”

•  trade monitoring; and

•  fair valuation of securities as described under “Pricing of Fund Shares.”

Generally, a purchase and redemption of Shares from the same Fund (i.e., “round trip”) within 90 calendar days may result in enforcement of a Fund’s excessive trading policies and procedures with respect to future purchase orders, provided that each Fund reserves the right to reject any purchase request as explained above.

The Funds monitor for patterns of shareholder frequent trading and may suspend or permanently terminate the exchange privilege of any investor who makes more than one round trip in a Fund over a 90-day period, and may bar future purchases into the Fund and any of the other Janus funds by such investor. The Funds’ excessive trading policies generally do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus funds by a Janus “fund of funds,” which is a fund that primarily invests in other Janus mutual funds; and (iii) identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with existing target allocations.

The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus fund, subject to 60 days’ notice to shareholders of that fund.

Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. The Funds, however, cannot always identify or reasonably detect excessive trading that may be facilitated by financial intermediaries or made difficult to identify through the use of omnibus accounts by those intermediaries that transmit purchase, exchange, and redemption orders to the Funds, and thus the Funds may have difficulty curtailing such activity. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.

In an attempt to detect and deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through

76 ï Janus Investment Fund

particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.

Certain transactions in Fund shares, such as periodic rebalancing through intermediaries (no more frequently than every 60 days) or those which are made pursuant to systematic purchase, exchange, or redemption programs generally do not raise excessive trading concerns and normally do not require application of the Funds’ methods to detect and deter excessive trading.

Each Fund also reserves the right to reject any purchase request (including exchange purchases) by any investor or group of investors for any reason without prior notice, including, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund. For example, a Fund may refuse a purchase order if the Fund’s portfolio managers and/or investment personnel believe they would be unable to invest the money effectively in accordance with the Fund’s investment policies or the Fund would otherwise be adversely affected due to the size of the transaction, frequency of trading, or other factors.

The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.

Excessive Trading Risks

Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.

Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. Although the Funds have adopted fair valuation policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies, under such circumstances there is potential for short-term arbitrage trades to dilute the value of Fund shares.

Although the Funds take steps to detect and deter excessive trading pursuant to the policies and procedures described in this Prospectus and approved by the Trustees, there is no assurance that these policies and procedures will be effective in limiting excessive trading in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.

Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.

AVAILABILITY OF PORTFOLIO HOLDINGS INFORMATION

The Mutual Fund Holdings Disclosure Policies and Procedures adopted by Janus Capital and all mutual funds managed within the Janus fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes policies and procedures with respect to disclosure of portfolio holdings.

•  Full Holdings. Each Fund is required to disclose its complete holdings in the quarterly holdings report on Form N-Q within 60 days of the end of each fiscal quarter, and in the annual report and semiannual report to Fund shareholders. These reports (i) are available on the SEC’s website at http://www.sec.gov; (ii) may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. (information on the Public Reference Room may be obtained by calling 1-800-SEC-0330); and (iii) are available without charge, upon request, by calling a Janus representative at

77 ï Janus Investment Fund

1-800-525-0020 (toll free). Portfolio holdings (excluding derivatives, short positions, and other investment positions), consisting of at least the names of the holdings, are generally available on a calendar quarter-end basis with a 30-day lag. Holdings are generally posted approximately two business days thereafter under each Fund’s Holdings & Details tab at janus.com/allfunds.

Each Fund may provide, upon request, historical full holdings on a monthly basis for periods prior to the previous quarter-end subject to a written confidentiality agreement.

•  Top Holdings. Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag.

•  Other Information. Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top performance contributors/detractors (consisting of security names in alphabetical order), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag. Top performance contributors/detractors provided at calendar quarter-end may include the percentage of contribution/detraction to Fund performance.

Full portfolio holdings will remain available on the Janus websites at least until a Form N-CSR or Form N-Q is filed with the SEC for the period that includes the date as of which the website information is current. Funds disclose their short positions, if applicable, only to the extent required in regulatory reports. Janus Capital may exclude from publication all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by Janus Capital’s Chief Investment Officer(s) or their delegates. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.

SHAREHOLDER SERVICES AND ACCOUNT POLICIES

Address Changes

For the easiest way to change the address on your account, visit janus.com/individual. You may also call a Janus representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.

Bank Account Changes

For the easiest way to change your bank account of record or add new bank account information to your account, visit janus.com/individual. You may also send a written request signed by the shareholder of record or each shareholder of record if more than one. Please note that you may change or add bank information online at janus.com/individual for purchases only. Certain tax-deferred accounts may require a written notice and, in some instances, bank privileges may not be available. We cannot accept changes or additions to bank account redemption options online at janus.com/individual or over the telephone. If the added bank account is a joint tenant/tenants in common account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.

Distributions

Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janus.com/individual, call a Janus representative, or send a written request signed by one or more shareholder(s) of record.

If you receive Fund distributions from an open non-retirement Fund account by check, and a distribution check sent to you at your address of record has been returned to Janus and you have failed to respond to follow up mailings from Janus, upon return of the follow up mailing the distribution check will be reinvested in your open Fund account at the next calculated NAV. In addition, your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.

78 ï Janus Investment Fund

Involuntary Redemptions

The Funds reserve the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Funds. This includes, but is not limited to, accounts that a Fund or its agents believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.

Online and Telephone Transactions

You may initiate many transactions through janus.com/individual or by calling Janus XpressLine™. You may also contact a Janus representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please visit janus.com/individual or call a Janus representative. The Funds and their agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.

Your account information should be kept private, and you should immediately review any account statements that you receive from Janus. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus immediately about any transactions you believe to be unauthorized.

Occasionally, we experience high call volumes due to unusual market activity or other events that may make it difficult for you to reach a Janus representative by telephone. If you are unable to reach a Janus representative by telephone, please consider visiting janus.com/individual, calling Janus XpressLine™, or sending written instructions.

Registration Changes

To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janus.com/individual or call a Janus representative for further instructions.

Statements, Reports, and Prospectuses

We will send you quarterly confirmations of all transactions. You may elect at janus.com/edelivery to discontinue delivery of your paper statements, and instead receive them online. In addition, at janus.com/individual, the Funds will send you an immediate transaction confirmation statement after every non-systematic transaction. If you have not elected to receive online statements, your confirmation will be mailed within two days of the transaction. The Funds reserve the right to charge a fee for additional account statement requests.

The Funds produce financial reports that include a complete list of each of the Funds’ portfolio holdings semiannually, and update their prospectus annually. You may elect to receive these reports and prospectus updates electronically at janus.com/edelivery. The Funds’ fiscal year ends September 30.

Unless you instruct Janus otherwise by contacting a Janus representative, the Funds will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Funds receive your instructions.

Taxpayer Identification Number

On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Funds to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Funds for any penalty that the IRS may impose.

Temporary Suspension of Services

The Funds or their agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Funds may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Funds to redeem their Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed

79 ï Janus Investment Fund

(except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.

Financial highlights

The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and the net expense ratio reflects expenses after any expense offset arrangement. Both expense ratios reflect expenses after waivers (reimbursements), if applicable. The information for the fiscal periods shown has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in the Annual Report, which is available upon request, and incorporated by reference into the SAI.

The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in Class D Shares of the Funds (assuming reinvestment of all dividends and distributions).

Class D Shares of certain Funds commenced operations on February 16, 2010, after the restructuring of the Funds’ Class J Shares, the predecessor share class. The financial highlights shown for periods prior to February 16, 2010 reflect financial results for the Class J Shares of each respective Fund. If Class D Shares had been available, the financial results shown may have been different.

Glossary of investment terms

This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.

EQUITY AND DEBT SECURITIES

Average-Weighted Effective Maturity is a measure of a bond’s maturity. The stated maturity of a bond is the date when the issuer must repay the bond’s entire principal value to an investor. Some types of bonds may also have an “effective maturity” that is shorter than the stated date due to prepayment or call provisions. Securities without prepayment or call provisions generally have an effective maturity equal to their stated maturity. Average-weighted effective maturity is calculated by averaging the effective maturity of bonds held by a Fund with each effective maturity “weighted” according to the percentage of net assets that it represents.

Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality. If a Fund purchases a participation interest, it may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender. Additional risks are involved in purchasing assignments. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. The Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of any collateral from a secured loan would satisfy a borrower’s obligations or that any collateral could be liquidated. A Fund may have difficulty trading assignments and participations to third parties or selling such securities in secondary markets, which in turn may affect the Fund’s NAV.

Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.

Certificates of Participation (“COPs”) are certificates representing an interest in a pool of securities. Holders are entitled to a proportionate interest in the underlying securities. Municipal lease obligations are often sold in the form of COPs. Refer to “Municipal lease obligations” below.

Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to investors seeking to invest idle cash. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended (the “1933 Act”).

Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.

Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.

Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.

Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).

Duration is the time it will take investors to recoup their investment in a bond. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity.

90 ï Janus Investment Fund

Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.

Exchange-traded funds (“ETFs”) are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Fixed-income securities are securities that pay a specified rate of return. The term generally includes short- and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.

High-yield/high-risk bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”

Industrial development bonds are revenue bonds that are issued by a public authority but which may be backed only by the credit and security of a private issuer and may involve greater credit risk. Refer to “Municipal securities” below.

Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis. These securities involve prepayment risk, which is the risk that the underlying mortgages or other debt may be refinanced or paid off prior to their maturities during periods of declining interest rates. In that case, a Fund may have to reinvest the proceeds from the securities at a lower rate. Potential market gains on a security subject to prepayment risk may be more limited than potential market gains on a comparable security that is not subject to prepayment risk.

Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts for property or equipment. Lease obligations may not be backed by the issuing municipality’s credit and may involve risks not normally associated with general obligation bonds and other revenue bonds. For example, their interest may become taxable if the lease is assigned and the holders may incur losses if the issuer does not appropriate funds for the lease payments on an annual basis, which may result in termination of the lease and possible default.

Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.

Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.

Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.

Pay-in-kind bonds are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.

Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.

Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans.

Rule 144A securities are securities that are not registered for sale to the general public under the 1933 Act, but that may be resold to certain institutional investors.

Standby commitment is a right to sell a specified underlying security or securities within a specified period of time and at an exercise price equal to the amortized cost of the underlying security or securities plus accrued interest, if any, at the time of exercise, that may be sold, transferred, or assigned only with the underlying security or securities. A standby commitment entitles the holder to receive same day settlement, and will be considered to be from the party to whom the investment company will look for payment of the exercise price.

Step coupon bonds are high-quality issues with above-market interest rates and a coupon that increases over the life of the bond. They may pay monthly, semiannual, or annual interest payments. On the date of each coupon payment, the issuer decides whether to call the bond at par, or whether to extend it until the next payment date at the new coupon rate.

Strip bonds are debt securities that are stripped of their interest (usually by a financial intermediary) after the securities are issued. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities of comparable maturity.

Tender option bonds are relatively long-term bonds that are coupled with the option to tender the securities to a bank, broker-dealer, or other financial institution at periodic intervals and receive the face value of the bond. This investment structure is commonly used as a means of enhancing a security’s liquidity.

U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.

Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate (the “underlying index”). The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.

Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.

Zero coupon bonds are debt securities that do not pay regular interest at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.

FUTURES, OPTIONS, AND OTHER DERIVATIVES

Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.

Derivatives are financial instruments whose performance is derived from the performance of another asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward contracts, swaps, and futures contracts.

Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component

92 ï Janus Investment Fund

may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form. An investment in equity-linked notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities, and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.

Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).

Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.

Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. A Fund may also buy options on futures contracts. An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.

Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments. A Fund bears the market risk of an investment in the underlying instruments, as well as the credit risk of the issuer.

Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).

Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.

Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.

Participatory notes are derivative securities which are linked to the performance of an underlying Indian security and which allow investors to gain market exposure to Indian securities without trading directly in the local Indian market.

Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period.

OTHER INVESTMENTS, STRATEGIES, AND/OR TECHNIQUES

Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles at the end of each day.

Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended (the “1940 Act”). Funds are classified as either “diversified” or “nondiversified.” To be classified as “diversified” under the 1940 Act, a fund

93 ï Janus Investment Fund

may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as “nondiversified” under the 1940 Act, on the other hand, has the flexibility to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.

Industry concentration for purposes under the 1940 Act is the investment of 25% or more of a Fund’s total assets in an industry or group of industries.

Leverage is when a Fund increases its assets available for investment using borrowings or similar transactions. Because short sales involve borrowing securities and then selling them, a Fund’s short sales effectively leverage the Fund’s assets. The use of leverage may make any change in a Fund’s NAV even greater and thus result in increased volatility of returns. A Fund’s assets that are used as collateral to secure the short sales may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage also creates interest expense that may lower a Fund’s overall returns.

Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.

Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.

Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash. These securities involve the risk that the seller will fail to repurchase the security, as agreed. In that case, a Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.

Reverse repurchase agreements involve the sale of a security by a Fund to another party (generally a bank or dealer) in return for cash and an agreement by the Fund to buy the security back at a specified price and time. This technique will be used primarily to provide cash to satisfy unusually high redemption requests, or for other temporary or emergency purposes.

Short sales in which a Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain. For short sales, the Fund will incur a loss if the value of a security increases during this period because it will be paying more for the security than it has received from the purchaser in the short sale. If the price declines during this period, a Fund will realize a short-term capital gain. Although a Fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security.

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. A Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

JANUS INVESTMENT FUND

This Statement of Additional Information includes information about 22 series of the Trust. Each Fund is a series of the Trust, an open-end, management investment company.

On July 6, 2009, as the result of the reorganization of funds of the Janus Adviser Series trust into the Trust, certain Funds discussed in this SAI assumed the assets and liabilities of the corresponding Janus Adviser Series funds (each, a “predecessor fund” and collectively, the “predecessor funds”). For this reason, certain historical information contained in this SAI for periods prior to July 6, 2009 is that of the predecessor funds.

Effective February 16, 2010, Class J Shares of the Funds that offered a Class J Shares (the initial share class) were restructured into two separate share classes. Shareholders who held their shares directly with Janus Capital were transitioned to a newly created share class called “Class D Shares.” Shareholders who held their shares through an intermediary remained in Class J Shares, which was renamed “Class T Shares.” As a result, certain historical information specific to Class D Shares and Class T Shares contained in this SAI for periods prior to February 16, 2010 (for those Funds that offered Class J Shares) is that of the initial share class.

CLASSIFICATION

The Investment Company Act of 1940, as amended (“1940 Act”), classifies mutual funds as either diversified or nondiversified. Janus Global Market Neutral Fund, Janus Global Select Fund, Janus Contrarian Fund, Janus Forty Fund, and Janus Twenty Fund are classified as nondiversified. Janus Global Real Estate Fund, Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Worldwide Fund, Janus Balanced Fund, Janus Enterprise Fund, Janus Fund, Janus Growth and Income Fund, Janus Research Fund, Janus Triton Fund, Janus Venture Fund, and Perkins Global Value Fund are classified as diversified.

ADVISER

Janus Capital Management LLC (“Janus Capital” or “Janus”) is the investment adviser for each Fund and is responsible for the general oversight of each subadviser.

SUBADVISERS

Fund subadvised by Janus Singapore. Janus Capital Singapore Pte. Limited (“Janus Singapore”) is the investment subadviser for Janus Asia Equity Fund.

Fund subadvised by Perkins. Perkins Investment Management LLC (“Perkins”) is the investment subadviser for Perkins Global Value Fund.

INVESTMENT POLICIES AND RESTRICTIONS APPLICABLE TO ALL FUNDS

The Funds are subject to certain fundamental policies and restrictions that may not be changed without shareholder approval. Shareholder approval means approval by the lesser of: (i) more than 50% of the outstanding voting securities of the Trust (or a particular Fund or particular class of shares if a matter affects just that Fund or that class of shares) or (ii) 67% or more of the voting securities present at a meeting if the holders of more than 50% of the outstanding voting securities of the Trust (or a particular Fund or class of shares) are present or represented by proxy. The following policies are fundamental policies of the Funds. Unless otherwise noted, each of these policies applies to each Fund, except policies (1) and (2), which apply only to the Funds specifically listed in those policies.

(1) With respect to 75% of its total assets, Janus Global Real Estate Fund, Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Worldwide Fund, Janus Balanced Fund, Janus Enterprise Fund, Janus Fund, Janus Growth and Income Fund, Janus Research Fund, Janus Triton Fund, Janus Venture Fund, and Perkins Global Value Fund may not purchase securities of an issuer (other than the U.S. Government, its agencies, instrumentalities or authorities, or repurchase agreements collateralized by U.S. Government securities, and securities of other investment companies) if: (a) such purchase would, at the time, cause more than 5% of the Fund’s total assets taken at market value to be invested in the securities of such issuer or (b) such purchase would, at the time, result in more than 10% of the outstanding voting securities of such issuer being held by the Fund.

2  

Each Fund may not:

(2) Invest 25% or more of the value of its total assets in any particular industry (other than U.S. Government securities), except that:

(i)	Janus Global Market Neutral Fund will not invest 25% or more of the value of its total assets in any particular industry (other than U.S. Government securities and securities of other investment companies).
(ii)	Janus Global Real Estate Fund will invest 25% or more of the value of its total assets in the real estate industries or real estate-related industries.
(iii)	Janus Global Life Sciences Fund will normally invest 25% or more of the value of its total assets, in aggregate, in the following industry groups: health care, pharmaceuticals, agriculture, cosmetics/personal care, and biotechnology.

(3) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this limitation shall not prevent a Fund from purchasing or selling foreign currencies, options, futures, swaps, forward contracts, or other derivative instruments, or from investing in securities or other instruments backed by physical commodities).

(4) Lend any security or make any other loan if, as a result, more than one-third of a Fund’s total assets would be lent to other parties (but this limitation does not apply to investments in repurchase agreements, commercial paper, debt securities, or loans, including assignments and participation interests).

(5) Act as an underwriter of securities issued by others, except to the extent that a Fund may be deemed an underwriter in connection with the disposition of its portfolio securities.

(6) Borrow money except that a Fund, with the exception of Janus Global Market Neutral Fund, may borrow money for temporary or emergency purposes (not for leveraging or investment). Borrowings from banks will not, in any event, exceed one-third of the value of a Fund’s total assets (including the amount borrowed). This policy shall not prohibit short sales transactions or futures, options, swaps, or forward transactions. The Funds may not issue “senior securities” in contravention of the 1940 Act.

In the case of Janus Global Market Neutral Fund, the Fund may not borrow money, except as permitted by the 1940 Act or exemptions therefrom and the rules and interpretive provisions of the Securities and Exchange Commission thereunder.

(7) Invest directly in real estate or interests in real estate; however, a Fund may own debt or equity securities issued by companies engaged in those businesses.

As a fundamental policy, a Fund may, notwithstanding any other investment policy or limitation (whether or not fundamental), invest all of its assets in the securities of a single open-end management investment company with substantially the same fundamental investment objectives, policies, and limitations as such Fund.

The Board of Trustees (“Trustees”) has adopted additional investment restrictions for the Funds. These restrictions are operating policies of the Funds and may be changed by the Trustees without shareholder approval. The additional restrictions adopted by the Trustees to date include the following:

(1) If a Fund is an approved underlying fund in a Janus fund of funds, the Fund may not acquire the securities of other investment companies or registered unit investment trusts in excess of the limits of Section 12(d)(1) of the 1940 Act in reliance on subparagraph (F) or subparagraph (G) of Section 12(d)(1).

(2) The Funds may sell securities short if they own or have the right to obtain securities equivalent in kind and amount to the securities sold short without the payment of any additional consideration therefor (“short sales against the box”). In addition, each Fund may engage in short sales other than against the box, which involve selling a security that a Fund borrows and does not own. The Trustees may impose limits on a Fund’s investments in short sales, as described in the Fund’s Prospectuses. Transactions in futures, options, swaps, and forward contracts not involving short sales are not deemed to constitute selling securities short.

(3) The Funds do not intend to purchase securities on margin, except that the Funds may obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments and other deposits in connection with transactions involving short sales, futures, options, swaps, forward contracts, and other permitted investment techniques shall not be deemed to constitute purchasing securities on margin.

  3

(4) A Fund may not mortgage or pledge any securities owned or held by such Fund in amounts that exceed, in the aggregate, 15% of that Fund’s net asset value (“NAV”), provided that this limitation does not apply to: reverse repurchase agreements; deposits of assets to margin; guarantee positions in futures, options, swaps, or forward contracts; or the segregation of assets in connection with such contracts.

In the case of Janus Global Market Neutral Fund, the Fund may not mortgage, pledge, hypothecate, or in manner transfer any securities or other assets owned or held by the Fund except in connection with permitted borrowings and in connection with margin deposits, security interests, liens, and collateral arrangements with respect to transactions involving short sales, options, futures contracts, and other permitted investment techniques.

(5) The Funds do not currently intend to purchase any security or enter into a repurchase agreement if, as a result, more than 15% of their respective net assets would be invested in repurchase agreements not entitling the holder to payment of principal and interest within seven days and in securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market. The Trustees, or the Funds’ investment adviser acting pursuant to authority delegated by the Trustees, may determine that a readily available market exists for: securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933, as amended (“Rule 144A Securities”), or any successor to such rule; Section 4(2) commercial paper; and municipal lease obligations. Accordingly, such securities may not be subject to the foregoing limitation.

(6) The Funds may not invest in companies for the purpose of exercising control of management.

Under the terms of an exemptive order received from the Securities and Exchange Commission (“SEC”), each Fund may borrow money from or lend money to other funds that permit such transactions and for which Janus Capital or one of its affiliates serves as investment adviser. All such borrowing and lending will be subject to the above limits and to the limits and other conditions in such exemptive order. A Fund will borrow money through the program only when the costs are equal to or lower than the cost of bank loans. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. A Fund will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). A Fund may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending Fund could result in a lost investment opportunity or additional borrowing costs.

For the purposes of these investment restrictions, the identification of the issuer of a municipal obligation depends on the terms and conditions of the security. When assets and revenues of a political subdivision are separate from those of the government that created the subdivision and the security is backed only by the assets and revenues of the subdivision, the subdivision is deemed to be the sole issuer. Similarly, in the case of an industrial development bond, if the bond is backed only by assets and revenues of a nongovernmental user, then the nongovernmental user would be deemed to be the sole issuer. If, however, in either case, the creating government or some other entity guarantees the security, the guarantee would be considered a separate security that would be treated as an issue of the guaranteeing entity.

For purposes of each Fund’s policies on investing in particular industries, as of the date of this SAI, each Fund relies primarily on industry or industry group classifications as published by Bloomberg L.P. To the extent that the Bloomberg L.P. classifications are so broad that the primary economic characteristics in a single class are materially different, a Fund may further classify issuers in accordance with industry classifications as published by the SEC or relevant SEC staff interpretations. The Funds intend to change industry or industry group classifications with respect to equity investments to Global Industry Classification Standard (“GICS”), but would continue to use Bloomberg L.P. for fixed-income investments. The Funds may change any source used for determining industry classifications without prior shareholder notice or approval.

INVESTMENT POLICIES APPLICABLE TO CERTAIN FUNDS

Janus Global Real Estate Fund. As a fundamental policy, the Fund will concentrate 25% or more of its total assets in securities of issuers in real estate industries or real estate-related industries.

Janus Global Life Sciences Fund. As a fundamental policy, Janus Global Life Sciences Fund will normally invest at least 25% of its total assets, in aggregate, in the following industry groups: health care, pharmaceuticals, agriculture, cosmetics/personal care, and biotechnology. Janus Global Life Sciences Fund does not have a policy to concentrate in any industry other than those listed above.

Janus Balanced Fund. As an operational policy, at least 25% of the assets of Janus Balanced Fund will normally be invested in fixed-income senior securities.

INVESTMENT STRATEGIES AND RISKS

Diversification

Funds are classified as either “diversified” or “nondiversified.” Diversification is a way to reduce risk by investing in a broad range of stocks or other securities. To be classified as “diversified” under the 1940 Act, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as “nondiversified” under the 1940 Act is not subject to the same restrictions and therefore has the ability to take larger positions in a smaller number of issuers than a fund that is classified as “diversified.” This gives a fund which is classified as nondiversified more flexibility to focus its investments in companies that the portfolio managers and/or investment personnel have identified as the most attractive for the investment objective and strategy of the fund. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of a fund.

Cash Position

As discussed in the Prospectuses, a Fund’s cash position may temporarily increase under various circumstances. Securities that the Funds may invest in as a means of receiving a return on idle cash include domestic or foreign currency denominated commercial paper, certificates of deposit, repurchase agreements, or other short-term debt obligations. These securities may include U.S. and foreign short-term cash instruments. Each Fund may also invest in affiliated or non-affiliated money market funds. (Refer to “Investment Company Securities.”)

Illiquid Investments

Although the Funds intend to invest in liquid securities, each Fund may invest up to 15% of its net assets in illiquid investments (i.e., securities that are not readily marketable). The Trustees have authorized Janus Capital to make liquidity determinations with respect to certain securities, including Rule 144A Securities, commercial paper, and municipal lease obligations purchased by the Funds. Under the guidelines established by the Trustees, Janus Capital will consider the following factors: (i) the frequency of trades and quoted prices for the security; (ii) the number of dealers willing to purchase or sell the security and the number of other potential purchasers; (iii) the willingness of dealers to undertake to make a market in the security; and (iv) the nature of the security and the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer. In the case of commercial paper, Janus Capital will also consider whether the paper is traded flat or in default as to principal and interest and any ratings of the paper by a nationally recognized statistical rating organization (“NRSRO”). Investments in Rule 144A Securities could have the effect of increasing the level of a Fund’s illiquidity to the extent that qualified institutional buyers become, for a time, uninterested in purchasing such securities. Certain securities previously deemed liquid may become illiquid in any subsequent assessment of the foregoing factors or other changes affecting the security. Foreign securities that may be freely traded on or through the facilities of an offshore exchange or other established offshore securities market are not restricted under the Funds’ liquidity procedures if traded in that market. Such securities will be treated as “restricted” if traded in the United States because foreign securities are not registered for sale under the U.S. Securities Act of 1933, as amended (the “1933 Act”).

If illiquid securities exceed 15% of a Fund’s net assets after the time of purchase, the Fund will take steps to reduce in an orderly fashion its holdings of illiquid securities. Because illiquid securities may not be readily marketable, the portfolio managers and/or investment personnel may not be able to dispose of them in a timely manner. As a result, the Fund may be forced to hold illiquid securities while their price depreciates. Depreciation in the price of illiquid securities may cause the NAV of a Fund to decline.

Each Fund may invest up to 5% of its total assets in venture capital investments measured at the time of an investment. A later increase or decrease in this percentage resulting from changes in values of assets will not constitute a violation of such limitation. Each Fund may make an initial investment of up to 0.5% of its total assets in any one venture capital company. A Fund may not invest in aggregate more than 1% of its total assets, measured at the time of the subsequent purchase, in any one venture capital company.

Venture capital investments are investments in new and early stage companies whose securities are not publicly traded. These investments may present significant opportunities for capital appreciation but involve a high degree of risk that can result in substantial losses. The Funds may not be able to sell such investments when the portfolio managers and/or investment personnel deem it appropriate to do so due to restrictions on their sale. In addition, the Funds may be forced to sell their venture capital investments at less than fair market value. Where venture capital investments must be registered prior to their

  5

sale, the Funds may be obligated to pay all or part of the registration expenses. Any of these situations may result in a decrease in a Fund’s NAV.

Securities Lending

Under procedures adopted by the Trustees, the Funds may seek to earn additional income by lending securities to qualified parties (typically brokers or other financial institutions) who need to borrow securities in order to complete, among other things, certain transactions such as covering short sales, avoiding failures to deliver securities, or completing arbitrage activities. There is the risk of delay in recovering a loaned security or the risk of loss in collateral rights if the borrower fails financially. In addition, Janus Capital makes efforts to balance the benefits and risks from granting such loans. The Funds do not have the right to vote on securities while they are being lent; however, the Funds may attempt to call back the loan and vote the proxy if time permits. All loans will be continuously secured by collateral which may consist of cash, U.S. Government securities, domestic and foreign short-term debt instruments, letters of credit, time deposits, repurchase agreements, money market mutual funds or other money market accounts, or such other collateral as permitted by the SEC. If a Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.

Upon receipt of cash collateral, Janus Capital may invest it in affiliated or non-affiliated cash management vehicles, whether registered or unregistered entities, as permitted by the 1940 Act and rules promulgated thereunder. Janus Capital currently intends to invest the cash collateral in a cash management vehicle for which Janus Capital serves as investment adviser. An investment in a cash management vehicle is generally subject to the same risks that shareholders experience when investing in similarly structured vehicles, such as the potential for significant fluctuations in assets as a result of the purchase and redemption activity of the securities lending program, a decline in the value of the collateral, and possible liquidity issues. Such risks may delay the return of the cash collateral and cause a Fund to violate its agreement to return the cash collateral to a borrower in a timely manner. As adviser to the Funds and the affiliated cash management vehicle in which the cash collateral is invested, Janus Capital has an inherent conflict of interest as a result of its fiduciary duties to both the Funds and the cash management vehicle. Additionally, Janus Capital receives an investment advisory fee of 0.05% for managing the cash management vehicle used for the securities lending program, but it may not receive a fee for managing certain other affiliated cash management vehicles in which the Funds may invest, and therefore may have an incentive to allocate preferred investment opportunities to investment vehicles for which it is receiving a fee.

Equity Securities

The Funds may invest in equity securities, which include, but are not limited to, common and preferred stocks, securities convertible or exchangeable into common stock, and warrants.

Common Stock. Common stock represents a proportionate share of the ownership of a company. Common stocks sometimes are divided into several classes, with each class having different voting rights, dividend rights, or other differences in their rights and priorities. The value of a stock is based on the market’s assessment of the current and future success of a company’s business, any income paid to stockholders, the value of the company’s assets, and general market conditions. The value of a stock may also be adversely affected by other factors such as accounting irregularities, actual or perceived weaknesses in corporate governance practices of a company’s board or management, and changes in company management. Common stock values can fluctuate dramatically over short periods.

Preferred Stock. A preferred stock represents an ownership interest in a company, but pays dividends at a specific rate and has priority over common stock in payment of dividends and liquidation claims. Preferred stock dividends are generally cumulative, noncumulative, or participating. “Cumulative” dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stock. “Participating” preferred stock may be entitled to a dividend exceeding the stated dividend in certain cases. Like debt securities, the value of a preferred stock often fluctuates more in response to changes in interest rates and the creditworthiness of the issuer, rather than in response to changes in the issuer’s profitability and business prospects. Preferred stock is subject to similar risks as common stock and debt securities.

Convertible Security. A convertible security is generally a debt obligation or preferred stock that may be converted within a specified period of time into a certain amount of common stock of the same or a different issuer. A convertible security, such as a “convertible preferred stock,” provides a fixed-income stream and the opportunity, through its conversion feature, to participate in the capital appreciation resulting from a market price advance in its underlying common stock. Like a common stock, the value of a convertible security tends to increase as the market value of the underlying stock rises, and it tends to

6  

decrease as the market value of the underlying stock declines. As with a fixed-income security, a convertible security tends to increase in market value when interest rates decline and decrease in value when interest rates rise. Because both interest rate and market movements can influence its value, a convertible security is not as sensitive to interest rates as a similar fixed-income security, nor is it as sensitive to changes in share price as its underlying stock.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at prices above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates.

A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by a Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Warrants. Warrants constitute options to purchase equity securities at a specific price and are valid for a specific period of time. They do not represent ownership of the equity securities, but only the right to buy them. Warrants have no voting rights, pay no dividends, and have no rights with respect to the assets of the corporation issuing them. Warrants differ from call options in that warrants are issued by the issuer of the security that may be purchased on their exercise, whereas call options may be issued by anyone. The prices of warrants do not necessarily move parallel to the prices of the underlying equity securities. The price usually represents a premium over the applicable market value of the common stock at the time of the warrant’s issuance. Investments in warrants involve certain risks, including the possible lack of a liquid market for the resale of the warrants, potential price fluctuations as a result of speculation or other factors, and failure of the price of the common stock to rise. The price of a warrant may be more volatile than the price of its underlying security. A warrant becomes worthless if it is not exercised within the specified time period.

Special Purpose Acquisition Companies. The Funds may invest in stock, warrants, and other securities of special purpose acquisition companies (“SPACs”) or similar entities that raise investor funds in order to seek acquisition or business combination opportunities. A SPAC may identify a specific industry or geographic region in which it intends to focus acquisition efforts, although many retain flexibility to invest in any industry or sector. Unless and until an acquisition is completed, a SPAC typically invests its assets (less a portion retained to cover expenses) in U.S. Government securities, money market securities, and cash. If a transaction that meets the requirements for the SPAC is not completed within a pre-established period of time, the invested funds are returned to the entity’s shareholders. Because SPACs and similar entities are in essence blank check companies without an operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to timely identify and complete a profitable acquisition. SPACs which pursue acquisitions only within certain industries or regions may be subject to price volatility related to such industries or regions. SPACs which trade in the over-the-counter market may be considered illiquid and/or be subject to restrictions on resale.

Natural Disasters and Extreme Weather Conditions

Certain areas of the world have historically been prone to and economically sensitive to environmental events such as, but not limited to, hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, tornadoes, mudslides or other weather-related phenomena. Such disasters, and the resulting physical or economic damage, could have a severe and negative impact on a Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses as they would under normal conditions. Adverse weather conditions may also have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

Foreign Securities

Within the parameters of its specific investment policies, each Fund may invest in foreign securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Investments in foreign securities, including securities of foreign and emerging markets governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:

  7

Currency Risk. As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.

Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in emerging markets which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominately based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

Regulatory Risk. There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.

Foreign Market Risk. Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.

Geographic Investment Risk. To the extent that a Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, or regulatory events in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.

Transaction Costs. Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Geographic Concentration Risk. Because Janus Asia Equity Fund intends to focus its investments in a particular geographic region, the Fund’s performance is expected to be closely tied to various factors such as the social, financial, economic, and political conditions within that region or country. Specifically, the Fund’s investments in Asian issuers increases the Fund’s exposure to various risks including, but not limited to, risks associated with volatile securities markets, currency fluctuations, social, political, and regulatory developments, economic environmental events (such as natural disasters), and changes in tax or economic policies, each of which, among others, may be particular to Asian countries or the region.

Because of Janus Asia Equity Fund’s investment focus on Asian issuers, its investments will be more sensitive to social, financial, economic, political, and regulatory developments affecting the fiscal stability of a particular country and/or the broader region. Events that negatively affect the fiscal stability of a particular country and/or the broader region may cause the value of the Fund’s holdings to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than a fund that is more geographically diverse in its investments.

The Asian region within which the Fund will focus its investments comprises countries in various stages of economic and political development. As a result, some countries may have relatively unstable governments or may experience adverse conditions such as overextension of credit, currency devaluations and restrictions, less efficient markets, rising unemployment, high inflation, underdeveloped financial services sectors, heavy reliance on international trade, prolonged economic recessions, and political instability, including military disruption, which could result in significant downturns and volatility in the economies of Asian countries and therefore have an adverse effect on the value of the Fund’s portfolio. Certain Asian countries may be vulnerable to trade barriers and other protectionist measures. Some countries have restricted the flow of

8  

money in and out of the country. Further, if Asian securities fall out of favor, it may cause the Fund to underperform funds that do not focus their investments in a single region of the world.

It is also possible that from time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region, and these companies and industries can be sensitive to social, financial, economic, political, and regulatory developments. The economies of the Asian countries in which the Fund invests may be interdependent, which could increase the possibility that conditions in one country will adversely impact the issuers of securities in a different country or region, or that the impact of such conditions will be experienced at the same time by the region as a whole. Likewise, the economies of the Asian region may also be dependent on the economies of other countries, such as the United States and Europe, and events in these economies could negatively impact the economies of the Asian region.

The trading volume on some Asian stock exchanges tends to be much lower than in the United States, and Asian securities of some companies are less liquid and more volatile than similar United States securities which could lead to a significant possibility of loss to the Fund. In addition, brokerage commissions on regional stock exchanges are fixed and are generally higher than the negotiated commissions in the United States.

Emerging Markets. Within the parameters of its specific investment policies, each Fund, particularly Janus Global Market Neutral Fund, Janus Asia Equity Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus Overseas Fund, Janus Worldwide Fund, and Perkins Global Value Fund, may invest its assets in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include, but are not limited to, countries included in the Morgan Stanley Capital International (“MSCI”) Emerging Markets Index^sm. Each of Janus Global Real Estate Fund and Janus International Equity Fund will normally limit its investments in emerging market countries to 15% and 20%, respectively, of its net assets. Janus Emerging Markets Fund will invest at least 80% of its net assets in companies from or with exposure to one or more “developing countries” or “emerging markets.” Such countries include any country that has been determined by an international organization, such as the World Bank, to have a low to middle income economy and/or any country that is not included in the Morgan Stanley Capital International World Index^sm, which measures the equity market performance of developed markets. Investing in emerging markets involves certain risks not typically associated with investing in the United States and imposes risks greater than, or in addition to, the risks associated with investing in securities of more developed foreign countries as previously discussed under “Foreign Securities.” The prices of investments in emerging markets can experience sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments. Many emerging market countries have experienced substantial, and in some periods extremely high, rates of inflation or deflation for many years, and future inflation may adversely affect the economies and securities markets of such countries. In addition, the economies of developing countries tend to be heavily dependent upon international trade and, as such, have been, and may continue to be, adversely impacted by trade barriers, exchange controls, managed adjustments in relative currency values, and other protectionist measures. These economies also have been, and may continue to be, adversely affected by economic conditions in the countries with which they do business.

The securities markets of many of the countries in which the Funds may invest may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for the Funds to obtain or to enforce a judgment against the issuers of such securities. In addition, there may be little financial or accounting information available with respect to issuers of emerging market securities, and it may be difficult as a result to assess the value of an investment in such securities. Further, a Fund’s ability to participate fully in the smaller, less liquid emerging markets may be limited by the policy restricting its investments in illiquid securities. The Funds may be subject to emerging markets risk to the extent that they invest in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. A summary of each Fund’s investments by country is contained in the Funds’ shareholder reports and Form N-Q reports, which are filed with the SEC.

Borrowing

Janus Global Market Neutral Fund may borrow money from banks for investment purposes to the extent permitted by the 1940 Act. This practice is known as leverage. Currently, under the 1940 Act, a Fund may borrow from banks up to one-third of its total assets (including the amount borrowed) provided that it maintains continuous asset coverage of 300% with respect to such borrowings and sells (within three days) sufficient portfolio holdings to restore such coverage if it should decline to less than 300% due to market fluctuations or otherwise, even if disadvantageous from an investment standpoint. Each Fund may borrow money to meet redemptions in order to avoid forced, unplanned sales of portfolio securities or for other temporary or emergency purposes. This allows a Fund greater flexibility to buy and sell portfolio securities for investment or tax considerations, rather than for cash flow considerations.

The use of borrowing by Janus Global Market Neutral Fund involves special risk considerations that may not be associated with other funds having similar policies. Because substantially all of a Fund’s assets fluctuate in value, whereas the interest obligation resulting from a borrowing will be fixed by the terms of the Fund’s agreement with its lender, the NAV per share of the Fund will tend to increase more when its portfolio securities increase in value and decrease more when its portfolio securities decrease in value than would otherwise be the case if the Fund did not borrow funds. In addition, interest costs on borrowings may fluctuate with changing market rates of interest and may partially offset or exceed the return earned on borrowed funds. Under adverse market conditions, a Fund might have to sell portfolio securities to meet interest or principal payments at a time when fundamental investment considerations would not favor such sales. The interest that the Fund must pay on borrowed money, together with any additional fees to maintain a line of credit or any minimum average balances required to be maintained, are additional costs that will reduce or eliminate any net investment income and may also offset any potential capital gains. Unless the appreciation and income, if any, on assets acquired with borrowed funds exceed the costs of borrowing, the use of leverage will diminish the investment performance of a Fund compared with what it would have been without leverage.

Short Sales

Each Fund may engage in “short sales against the box.” This technique involves either selling short a security that a Fund owns, or selling short a security that a Fund has the right to obtain, for delivery at a specified date in the future. A Fund does not deliver from its portfolio the securities sold short and does not immediately receive the proceeds of the short sale. A Fund borrows the securities sold short and receives proceeds from the short sale only when it delivers the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, a Fund loses the opportunity to participate in the gain.

Each Fund may also engage in other short sales. A Fund may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. In a short sale transaction, a Fund sells a security it does not own to a purchaser at a specified price. To complete a short sale, the Fund must: (i) borrow the security to deliver it to the purchaser and (ii) buy that same security in the market to return it to the lender. Short sales involve the same fundamental risk as short sales against the box, as described in the previous paragraph. In addition, the Fund may incur a loss as a result of the short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security, and the Fund may realize a gain if the security declines in price between those same dates. Although a Fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, the potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. To borrow the security, the Fund may also be required to pay a premium, which would increase the cost of the security sold.

The Funds may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request that the borrowed securities be returned to it on short notice, and a Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, it is more likely that a Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale.

Until a Fund closes its short position or replaces the borrowed security, the Fund may designate liquid assets it owns (other than the short sale proceeds) as segregated assets to the books of the broker and/or its custodian in an amount equal to its obligation to purchase the securities sold short, as required by the 1940 Act. The amount segregated in this manner is expected to be increased or decreased each business day equal to the change in market value of the Fund’s obligation to purchase the security sold short. The proceeds of the short sale will be retained by the broker, to the extent necessary to meet the margin requirements, until the short position is closed out. If the lending broker requires the Fund to deposit

10  

additional collateral (in addition to the short sales proceeds that the broker holds during the period of the short sale), which may be as much as 50% of the value of the securities sold short, the amount of the additional collateral may be deducted in determining the amount of cash or liquid assets the Fund is required to segregate to cover the short sale obligation pursuant to the 1940 Act. The amount segregated must be unencumbered by any other obligation or claim other than the obligation that is being covered. A Fund believes that short sale obligations that are covered, either by an offsetting asset or right (acquiring the security sold short or having an option to purchase the security sold short at an exercise price that covers the obligation), or by the Fund’s segregated asset procedures (or a combination thereof), are not senior securities under the 1940 Act and are not subject to the Fund’s borrowing restrictions. This requirement to segregate assets limits a Fund’s leveraging of its investments and the related risk of losses from leveraging. A Fund also is required to pay the lender of the security any dividends or interest that accrues on a borrowed security during the period of the loan. Depending on the arrangements made with the broker or custodian, a Fund may or may not receive any payments (including interest) on collateral it has deposited with the broker. A Fund’s ability to invest in short sales may be limited, as described in the Fund’s Prospectuses.

Zero Coupon, Step Coupon, and Pay-In-Kind Securities

Within the parameters of its specific investment policies, each Fund may invest up to 10% of its net assets in zero coupon, step coupon, and pay-in-kind securities. Zero coupon bonds are issued and traded at a discount from their face value. They do not entitle the holder to any periodic payment of interest prior to maturity. Step coupon bonds are high-quality issues with above-market interest rates and a coupon that increases over the life of the bond. They may pay monthly, semiannual, or annual interest payments. On the date of each coupon payment, the issuer decides whether to call the bond at par or whether to extend it until the next payment date at the new coupon rate. Pay-in-kind bonds normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made. For the purposes of a Fund’s restriction on investing in income-producing securities, income-producing securities include securities that make periodic interest payments as well as those that make interest payments on a deferred basis or pay interest only at maturity (e.g., Treasury bills or zero coupon bonds).

For federal income tax purposes, holders of zero coupon securities and step coupon securities are required to recognize income even though the holders receive no cash payments of interest during the year. Similarly, holders of payment-in-kind securities must include in their gross income the value of securities they receive as “interest.” In order to qualify as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended, and the regulations thereunder, a Fund must distribute its investment company taxable income, including the original issue discount accrued on zero coupon or step coupon bonds and non-cash income from payment-in-kind securities. Because a Fund will not receive cash payments on a current basis with respect to accrued original-issue discount on zero coupon bonds or step coupon bonds during the period before interest payments begin or may receive non-cash interest payments, in some years that Fund may have to distribute cash obtained from other sources in order to satisfy the distribution requirements under the Internal Revenue Code. A Fund may obtain such cash from selling other portfolio holdings, which may cause that Fund to incur capital gains or losses on the sale. Additionally, these actions are likely to reduce the amount of cash available for investment by a Fund, to reduce the assets to which Fund expenses could be allocated, and to reduce the rate of return for that Fund. In some circumstances, such sales might be necessary in order to satisfy cash distribution requirements even though investment considerations might otherwise make it undesirable for a Fund to sell the securities at the time.

Generally, the market prices of zero coupon, step coupon, and pay-in-kind securities are more volatile than the prices of securities that pay interest periodically and in cash and are likely to respond to changes in interest rates to a greater degree than other types of debt securities having similar maturities and credit quality.

Pass-Through Securities

The Funds may invest in various types of pass-through securities, such as mortgage-backed securities, asset-backed securities, credit-linked trust certificates, traded custody receipts, and participation interests. A pass-through security is a share or certificate of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer. The purchaser of a pass-through security receives an undivided interest in the underlying pool of securities. The issuers of the underlying securities make interest and principal payments to the intermediary, which are passed through to purchasers, such as the Funds. The most common type of pass-through securities is mortgage-backed securities. Government National Mortgage Association (“Ginnie Mae”) Certificates are mortgage-backed securities that evidence an undivided interest in a pool of mortgage loans. Ginnie Mae Certificates differ from bonds in that principal is paid back monthly by the borrowers over the term of the loan rather than returned in a lump sum at maturity. A Fund will generally purchase “modified pass-through” Ginnie Mae Certificates, which entitle the holder to receive a share of all interest and principal

  11

payments paid and owned on the mortgage pool, net of fees paid to the “issuer” and Ginnie Mae, regardless of whether or not the mortgagor actually makes the payment. Ginnie Mae Certificates are backed as to the timely payment of principal and interest by the full faith and credit of the U.S. Government.

The Federal Home Loan Mortgage Corporation (“Freddie Mac”) issues two types of mortgage pass-through securities: mortgage participation certificates (“PCs”) and guaranteed mortgage certificates (“GMCs”). PCs resemble Ginnie Mae Certificates in that each PC represents a pro rata share of all interest and principal payments made and owned on the underlying pool. Freddie Mac guarantees timely payments of interest on PCs and the full return of principal. GMCs also represent a pro rata interest in a pool of mortgages. However, these instruments pay interest semiannually and return principal once a year in guaranteed minimum payments. This type of security is guaranteed by Freddie Mac as to timely payment of principal and interest, but it is not guaranteed by the full faith and credit of the U.S. Government.

The Federal National Mortgage Association (“Fannie Mae”) issues guaranteed mortgage pass-through certificates (“Fannie Mae Certificates”). Fannie Mae Certificates resemble Ginnie Mae Certificates in that each Fannie Mae Certificate represents a pro rata share of all interest and principal payments made and owned on the underlying pool. This type of security is guaranteed by Fannie Mae as to timely payment of principal and interest, but it is not guaranteed by the full faith and credit of the U.S. Government.

In September 2008, the Federal Housing Finance Agency (“FHFA”), an agency of the U.S. Government, placed Fannie Mae and Freddie Mac under conservatorship to provide stability in the financial markets, mortgage availability and taxpayer protection by preserving Fannie Mae’s and Freddie Mac’s assets, and placing them in a sound and solvent condition. Under the conservatorship, the management of Fannie Mae and Freddie Mac was replaced. The effect that the FHFA’s conservatorship will have on Fannie Mae’s and Freddie Mac’s debt and equities is unclear.

Except for GMCs, each of the mortgage-backed securities described above is characterized by monthly payments to the holder, reflecting the monthly payments made by the borrowers who received the underlying mortgage loans. The payments to the security holders (such as the Funds), like the payments on the underlying loans, represent both principal and interest. Although the underlying mortgage loans are for specified periods of time, such as 20 or 30 years, the borrowers can, and typically do, pay them off sooner. Thus, the security holders frequently receive prepayments of principal in addition to the principal that is part of the regular monthly payments. The portfolio managers and/or investment personnel will consider estimated prepayment rates in calculating the average-weighted maturity of a Fund, if relevant. A borrower is more likely to prepay a mortgage that bears a relatively high rate of interest. This means that in times of declining interest rates, higher yielding mortgage-backed securities held by a Fund might be converted to cash, and the Fund will be forced to accept lower interest rates when that cash is used to purchase additional securities in the mortgage-backed securities sector or in other investment sectors. Additionally, prepayments during such periods will limit a Fund’s ability to participate in as large a market gain as may be experienced with a comparable security not subject to prepayment.

The Funds’ investments in mortgage-backed securities may be backed by subprime mortgages. Subprime mortgages are loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their mortgages. Investments in mortgage-backed securities comprised of subprime mortgages may be subject to a higher degree of credit risk, valuation risk, and liquidity risk.

Asset-backed securities represent interests in pools of consumer loans and are backed by paper or accounts receivables originated by banks, credit card companies, or other providers of credit. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. Tax-exempt asset-backed securities include units of beneficial interests in pools of purchase contracts, financing leases, and sales agreements that may be created when a municipality enters into an installment purchase contract or lease with a vendor. Such securities may be secured by the assets purchased or leased by the municipality; however, if the municipality stops making payments, there generally will be no recourse against the vendor. The market for tax-exempt, asset-backed securities is still relatively new. These obligations are likely to involve unscheduled prepayments of principal.

The Funds also may invest in other types of pass-through securities, such as credit-linked trust certificates, traded custody receipts, and participation interests. Holders of the interests are entitled to receive distributions of interest, principal, and other payments on each of the underlying debt securities (less expenses), and in some cases distributions of the underlying debt securities. The underlying debt securities have a specified maturity but are subject to prepayment risk because if an issuer prepays the principal, a Fund may have additional cash to invest at a time when prevailing interest rates have declined and reinvestment of such additional funds is made at a lower rate. The value of the underlying debt securities may change

12  

due to changes in market interest rates. If interest rates rise, the value of the underlying debt securities, and therefore the value of the pass-through security, may decline. If the underlying debt securities are high-yield securities, the risks associated with high-yield/high-risk securities discussed in this SAI and in the Funds’ Prospectuses may apply.

Investment Company Securities

From time to time, the Funds may invest in securities of other investment companies, subject to the provisions of the 1940 Act and any applicable SEC exemptive orders. Section 12(d)(1) of the 1940 Act prohibits a Fund from acquiring: (i) more than 3% of another investment company’s voting stock; (ii) securities of another investment company with a value in excess of 5% of a Fund’s total assets; or (iii) securities of such other investment company and all other investment companies owned by a Fund having a value in excess of 10% of the Fund’s total assets. In addition, Section 12(d)(1) prohibits another investment company from selling its shares to a Fund if, after the sale: (i) the Fund owns more than 3% of the other investment company’s voting stock or (ii) the Fund and other investment companies, and companies controlled by them, own more than 10% of the voting stock of such other investment company. If a Fund is an approved underlying fund in a Janus fund of funds, the Fund may not acquire the securities of other investment companies or registered unit investment trusts in excess of the limits of Section 12(d)(1) of the 1940 Act in reliance on subparagraph (F) or subparagraph (G) of Section 12(d)(1). The Funds may invest their cash holdings in affiliated or non-affiliated money market funds as part of a cash sweep program. The Funds may purchase unlimited shares of affiliated or non-affiliated money market funds and of other funds managed by Janus Capital, whether registered or unregistered entities, as permitted by the 1940 Act and rules promulgated thereunder and/or an SEC exemptive order. To the extent the Funds invest in money market funds or other funds, the Funds will be subject to the same risks that investors experience when investing in such other funds. These risks may include the impact of significant fluctuations in assets as a result of the cash sweep program or purchase and redemption activity by affiliated or non-affiliated shareholders in such other funds. Additionally, as the adviser to the Funds and the money market funds or other funds or investment vehicles in which the Funds may invest, Janus Capital has an inherent conflict of interest because it has fiduciary duties to both the Funds and the money market funds and other funds.

Investment companies may include index-based investments such as exchange-traded funds (“ETFs”), which hold substantially all of their assets in investments representing specific indices. The main risk of investing in index-based investments is the same as investing in a portfolio of investments comprising the index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operation. The market prices of index-based investments will fluctuate in accordance with both changes in the market value of their underlying portfolio investments and due to supply and demand for the instruments on the exchanges on which they are traded (which may result in their trading at a discount or premium to their NAVs). Index-based investments may not replicate exactly the performance of their specific index because of transaction costs and because of the temporary unavailability of certain component securities of the index. Some ETFs have obtained exemptive orders permitting other investment companies, such as the Funds, to acquire their securities in excess of the limits of the 1940 Act.

Exchange-Traded Notes

The Funds may invest in exchange-traded notes (“ETNs”), which are senior, unsecured, unsubordinated debt securities whose returns are linked to a particular index and provide exposure to the total returns of various market indices, including indices linked to stocks, bonds, commodities and currencies. This type of debt security differs from other types of bonds and notes. ETN returns are based upon the performance of a market index minus applicable fees; no period coupon payments are distributed and no principal protections exist. ETNs do not pay cash distributions. Instead, the value of dividends, interest, and investment gains are captured in a Fund’s total return. A Fund may invest in these securities when desiring exposure to debt securities or commodities. When evaluating ETNs for investment, Janus Capital or the subadviser, as applicable, will consider the potential risks involved, expected tax efficiency, rate of return, and credit risk. When a Fund invests in ETNs, it will bear its proportionate share of any fees and expenses borne by the ETN. There may be restrictions on a Fund’s right to redeem its investment in an ETN, which are meant to be held until maturity. A Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market.

Depositary Receipts

Each Fund may invest in sponsored and unsponsored American Depositary Receipts (“ADRs”), which are receipts issued by an American bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. ADRs, in registered form, are designed for use in U.S. securities markets. Unsponsored ADRs may be created without the participation of the foreign issuer. Holders of these ADRs generally bear all the costs of the ADR facility, whereas foreign issuers typically bear certain costs in a sponsored ADR. The bank or trust company depositary of an unsponsored ADR may be under no

  13

obligation to distribute shareholder communications received from the foreign issuer or to pass through voting rights. The Funds may also invest in European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”), and in other similar instruments representing securities of foreign companies. EDRs and GDRs are securities that are typically issued by foreign banks or foreign trust companies, although U.S. banks or U.S. trust companies may issue them. EDRs and GDRs are structured similarly to the arrangements of ADRs. EDRs, in bearer form, are designed for use in European securities markets.

Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, political and economic risk, regulatory risk, market risk, and geographic investment risk, because their values depend on the performance of a foreign security denominated in its home currency. The risks of foreign investing are addressed in some detail in the Funds’ Prospectuses.

U.S. Government Securities

To the extent permitted by its investment objective and policies, each Fund, particularly Janus Balanced Fund, may invest in U.S. Government securities. The 1940 Act defines U.S. Government securities to include securities issued or guaranteed by the U.S. Government, its agencies, and its instrumentalities. U.S. Government securities may also include repurchase agreements collateralized by and municipal securities escrowed with or refunded with U.S. Government securities. U.S. Government securities in which a Fund may invest include U.S. Treasury securities, including Treasury Inflation Protection Securities (“TIPS”), and obligations issued or guaranteed by U.S. Government agencies and instrumentalities that are backed by the full faith and credit of the U.S. Government, such as those issued or guaranteed by the Small Business Administration, Maritime Administration, Export-Import Bank of the United States, Farmers Home Administration, Federal Housing Administration, and Ginnie Mae. In addition, U.S. Government securities in which a Fund may invest include securities backed only by the rights of the issuers to borrow from the U.S. Treasury, such as those issued by the Federal Farm Credit Bank, Federal Intermediate Credit Banks, Tennessee Valley Authority, and Freddie Mac. Securities issued by Fannie Mae, the Federal Home Loan Banks, and the Student Loan Marketing Association (“Sallie Mae”) are supported by the discretionary authority of the U.S. Government to purchase the obligations. There is no guarantee that the U.S. Government will support securities not backed by its full faith and credit. Accordingly, although these securities have historically involved little risk of loss of principal if held to maturity, they may involve more risk than securities backed by the full faith and credit of the U.S. Government because the Funds must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment.

Municipal Obligations

The Funds may invest in municipal obligations issued by states, territories, and possessions of the United States and the District of Columbia. The value of municipal obligations can be affected by changes in their actual or perceived credit quality. The credit quality of municipal obligations can be affected by, among other things, the financial condition of the issuer or guarantor, the issuer’s future borrowing plans and sources of revenue, the economic feasibility of the revenue bond project or general borrowing purpose, political or economic developments in the region where the security is issued, and the liquidity of the security. Because municipal securities are generally traded over-the-counter, the liquidity of a particular issue often depends on the willingness of dealers to make a market in the security. The liquidity of some municipal obligations may be enhanced by demand features, which would enable a Fund to demand payment on short notice from the issuer or a financial intermediary.

Other Income-Producing Securities

Other types of income-producing securities that the Funds may purchase include, but are not limited to, the following types of securities:

Inverse floaters. Inverse floaters are debt instruments whose interest bears an inverse relationship to the interest rate on another security. No Fund will invest more than 5% of its assets in inverse floaters. Similar to variable and floating rate obligations, effective use of inverse floaters requires skills different from those needed to select most portfolio securities. If movements in interest rates are incorrectly anticipated, a Fund could lose money, or its NAV could decline by the use of inverse floaters.

Standby commitments. Standby commitments are the rights to sell a specified underlying security or securities within a specified period of time and at an exercise price equal to the amortized cost of the underlying security or securities plus accrued interest, if any, at the time of exercise, that may be sold, transferred, or assigned only with the underlying security or securities. A standby commitment entitles the holder to receive same day settlement and will be considered to be from the party to whom the investment company will look for payment of the exercise price.

14  

Strip bonds. Strip bonds are debt securities that are stripped of their interest (usually by a financial intermediary) after the securities are issued. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities of comparable maturity.

Tender option bonds. Tender option bonds are relatively long-term bonds that are coupled with the option to tender the securities to a bank, broker-dealer, or other financial institution at periodic intervals and receive the face value of the bonds. This investment structure is commonly used as a means of enhancing a security’s liquidity.

The Funds will purchase standby commitments, tender option bonds, and instruments with demand features primarily for the purpose of increasing the liquidity of their portfolio holdings.

Variable and floating rate obligations. These types of securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate (the “underlying index”). The floating rate tends to decrease the security’s price sensitivity to changes in interest rates. These types of securities are relatively long-term instruments that often carry demand features permitting the holder to demand payment of principal at any time or at specified intervals prior to maturity.

In order to most effectively use these investments, the portfolio managers and/or investment personnel must correctly assess probable movements in interest rates. This involves different skills than those used to select most portfolio securities. If the portfolio managers and/or investment personnel incorrectly forecast such movements, a Fund could be adversely affected by the use of variable or floating rate obligations.

Real Estate Investment Trusts (“REITs”)

Within the parameters of its specific investment policies, each Fund may invest in REITs. Janus Global Real Estate Fund may invest a significant amount of its assets in these types of securities. REITs are sometimes informally characterized as equity REITs, mortgage REITs, and hybrid REITs. Investment in REITs may subject a Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition, and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent, and fluctuations in rental income. Equity REITs generally experience these risks directly through fee or leasehold interests, whereas mortgage REITs generally experience these risks indirectly through mortgage interests, unless the mortgage REIT forecloses on the underlying real estate. Changes in interest rates may also affect the value of a Fund’s investment in REITs. For instance, during periods of declining interest rates, certain mortgage REITs may hold mortgages that the mortgagors elect to prepay, and prepayment may diminish the yield on securities issued by those REITs.

Certain REITs have relatively small market capitalizations, which may tend to increase the volatility of the market price of their securities. Furthermore, REITs are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code and to maintain exemption from the registration requirements of the 1940 Act. By investing in REITs indirectly through a Fund, a shareholder will bear not only his or her proportionate share of the expenses of a Fund, but also, indirectly, similar expenses of the REITs. In addition, REITs depend generally on their ability to generate cash flow to make distributions to shareholders.

Repurchase and Reverse Repurchase Agreements

In a repurchase agreement, a Fund purchases a security and simultaneously commits to resell that security to the seller at an agreed upon price on an agreed upon date within a number of days (usually not more than seven) from the date of purchase. The resale price consists of the purchase price plus an agreed upon incremental amount that is unrelated to the coupon rate or maturity of the purchased security. A repurchase agreement involves the obligation of the seller to pay the agreed upon price, which obligation is in effect secured by the value (at least equal to the amount of the agreed upon resale price and marked-to-market daily) of the underlying security or “collateral.” A risk associated with repurchase agreements is the failure of the seller to repurchase the securities as agreed, which may cause a Fund to suffer a loss if the market value of such securities declines before they can be liquidated on the open market. In the event of bankruptcy or insolvency of the seller, a Fund may encounter delays and incur costs in liquidating the underlying security. In addition, the collateral received in the repurchase transaction may become worthless. To the extent a Fund’s collateral focuses in one or more sectors, such as banks and financial services, the Fund is subject to increased risk as a result of that exposure. Repurchase agreements that mature

  15

in more than seven days are subject to the 15% limit on illiquid investments. While it is not possible to eliminate all risks from these transactions, it is the policy of the Funds to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory by Janus Capital. There is no guarantee that Janus Capital’s analysis of the creditworthiness of the counterparty will be accurate, and the underlying collateral involved in the transaction can expose a Fund to additional risk regardless of the creditworthiness of the parties involved in the transaction.

Reverse repurchase agreements are transactions in which a Fund sells a security and simultaneously commits to repurchase that security from the buyer, such as a bank or broker-dealer, at an agreed upon price on an agreed upon future date. The resale price in a reverse repurchase agreement reflects a market rate of interest that is not related to the coupon rate or maturity of the sold security. For certain demand agreements, there is no agreed upon repurchase date and interest payments are calculated daily, often based upon the prevailing overnight repurchase rate. The Funds will use the proceeds of reverse repurchase agreements only to satisfy unusually heavy redemption requests or for other temporary or emergency purposes without the necessity of selling portfolio securities, or to earn additional income on portfolio securities, such as Treasury bills or notes.

Generally, a reverse repurchase agreement enables a Fund to recover for the term of the reverse repurchase agreement all or most of the cash invested in the portfolio securities sold and to keep the interest income associated with those portfolio securities. Such transactions are only advantageous if the interest cost to a Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. In addition, interest costs on the money received in a reverse repurchase agreement may exceed the return received on the investments made by a Fund with those monies. Using reverse repurchase agreements to earn additional income involves the risk that the interest earned on the invested proceeds is less than the expense of the reverse repurchase agreement transaction. This technique may also have a leveraging effect on a Fund’s portfolio, although a Fund’s intent to segregate assets in the amount of the reverse repurchase agreement minimizes this effect. While a reverse repurchase agreement is outstanding, a Fund will maintain cash and appropriate liquid assets in a segregated custodial account to cover its obligation under the agreement. A Fund will enter into reverse repurchase agreements only with parties that Janus Capital deems creditworthy.

Mortgage Dollar Rolls

Certain Funds, particularly Janus Global Market Neutral Fund and Janus Global Real Estate Fund, may enter into “mortgage dollar rolls,” which are similar to reverse repurchase agreements in certain respects. In a “mortgage dollar roll” transaction, a Fund sells a mortgage-related security (such as a Ginnie Mae security) to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash. Unlike in the case of reverse repurchase agreements, the dealer with which a Fund enters into a dollar roll transaction is not obligated to return the same securities as those originally sold by the Fund, but only securities which are “substantially identical.” To be considered “substantially identical,” the securities returned to a Fund generally must: (i) be collateralized by the same types of underlying mortgages; (ii) be issued by the same agency and be part of the same program; (iii) have a similar original stated maturity; (iv) have identical net coupon rates; (v) have similar market yields (and, therefore, price); and (vi) satisfy “good delivery” requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within 2.5% of the initial amount delivered.

A Fund’s obligations under a dollar roll agreement must be covered by cash, U.S. Government securities, or other liquid high grade debt obligations equal in value to the securities subject to repurchase by a Fund, maintained in a segregated account. To the extent that the Fund collateralizes its obligations under a dollar roll agreement, the asset coverage requirements of the 1940 Act will not apply to such transactions. Furthermore, under certain circumstances, an underlying mortgage-backed security that is part of a dollar roll transaction may be considered illiquid. During the roll period, a Fund foregoes principal and interest paid on the mortgage-backed security. A Fund is compensated by the difference between the current sale price and the lower forward purchase price, often referred to as the “drop,” as well as the interest earned on the cash proceeds of the initial sale.

Successful use of mortgage dollar rolls depends on a Fund’s ability to predict interest rates and mortgage payments. Dollar roll transactions involve the risk that the market value of the securities a Fund is required to purchase may decline below the agreed upon repurchase price.

Bank Loans

Certain Funds, particularly Janus Global Market Neutral Fund and Janus Global Technology Fund (no more than 5% of each Fund’s total assets) and Janus Balanced Fund (no more than 20% of the Fund’s total assets), may invest in bank loans, which include institutionally-traded floating rate securities.

Bank loans, which include institutionally-traded floating rate securities, are obligations of companies or other entities that are typically issued in connection with recapitalizations, acquisitions, and refinancings. Bank loans often involve borrowers whose financial conditions are troubled or uncertain and companies that are highly leveraged. Borrowers may include companies who are involved in bankruptcy proceedings. The Funds generally invest in bank loans directly through an agent, either by assignment from another holder of the loan or as a participation interest in another holder’s portion of the loan. Assignments and participations involve credit risk, interest rate risk, and liquidity risk.

When a Fund purchases an assignment, the Fund generally assumes all the rights and obligations under the loan agreement and will generally become a “lender” for purposes of the particular loan agreement. The rights and obligations acquired by a Fund under an assignment may be different, and be more limited, than those held by an assigning lender. Subject to the terms of a loan agreement, a Fund may enforce compliance by a borrower with the terms of the loan agreement and may have rights with respect to any funds acquired by other lenders through set-off. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. A Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of collateral from a secured loan would satisfy the borrower’s obligations or that the collateral could be liquidated.

If a Fund purchases a participation interest, it typically will have a contractual relationship with the lender and not with the borrower. A Fund may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender, or any other intermediate participant. A Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender and only upon receipt by the lender of the payments from the borrower. The failure by a Fund to receive scheduled interest or principal payments may adversely affect the income of the Fund and may likely reduce the value of its assets, which would be reflected by a reduction in the Fund’s NAV.

The borrower of a loan in which a Fund holds an assignment or participation interest may, either at its own election or pursuant to the terms of the loan documentation, prepay amounts of the loan from time to time. There is no assurance that a Fund will be able to reinvest the proceeds of any loan prepayment at the same interest rate or on the same terms as those of the original loan participation. This may result in a Fund realizing less income on a particular investment and replacing the loan with a less attractive security, which may provide less return to the Fund.

Floating Rate Loans

Floating rate loans typically are negotiated, structured, and originated by a bank or other financial institution (an “agent”) for a lending group or “syndicate” of financial institutions. In most cases, a Fund relies on the agent to assert appropriate creditor remedies against the borrower. The agent may not have the same interests as the Fund, and the agent may determine to waive certain covenants contained in the loan agreement that the Fund would not otherwise have determined to waive. The typical practice of an agent relying on reports from a borrower about its financial condition may involve a risk of fraud by a borrower. In addition, if an agent becomes insolvent or carries out its duties improperly, the Fund may experience delays in realizing payment and/or risk loss of principal and/or income on its floating rate loan investments. The investment team performs a credit analysis on the borrower but typically does not perform credit analysis on the agent or other intermediate participants.

Floating rate loans have interest rates which adjust periodically and are tied to a benchmark lending rate such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a short-term interest rate that banks charge one another and is generally representative of the most competitive and current cash rates. In other cases, the lending rate could be tied to the prime rate offered by one or more major U.S. banks (“Prime Rate”) or the rate paid on large certificates of deposit traded in the secondary markets (“CD rate”). The interest rate on Prime Rate based loans and corporate debt securities may float daily as the Prime Rate changes, while the interest rate on LIBOR or CD rate based loans and corporate debt securities may reset periodically. If the benchmark lending rate changes, the rate payable to lenders under the loan will change at the next scheduled adjustment date specified in the loan agreement. Investing in floating rate loans with longer interest rate reset periods may increase fluctuations in a Fund’s NAV as a result of changes in interest rates. A Fund may attempt to hedge against interest rate fluctuations by entering into interest rate swaps or by using other hedging techniques.

  17

While the Funds generally expect to invest in fully funded term loans, certain of the loans in which the Funds may invest include revolving loans and delayed draw term loans. Such loans generally obligate the lender (and those with an interest in the loan) to fund the loan at the borrower’s discretion. As such, a Fund would need to maintain amounts sufficient to meet its contractual obligations. In cases where a Fund invests in revolving loans and delayed draw term loans, the Fund will maintain high quality liquid assets in an amount at least equal to its obligations under the loans. Amounts maintained in high-quality liquid assets may provide less return to a Fund than investments in floating rate loans. Loans involving revolving credit facilities or delayed terms may require a Fund to increase its investment in a particular floating rate loan when it otherwise would not have done so. Further, a Fund may be obligated to do so even if it may be unlikely that the borrower will repay amounts due.

Purchasers of floating rate loans may pay and/or receive certain fees. The Funds may receive fees such as covenant waiver fees or prepayment penalty fees. A Fund may pay fees such as facility fees. Such fees may affect the Fund’s return.

The Funds do not intend to purchase floating rate loans through private placements or other transactions that may involve confidential information. Such a policy may place a Fund at a disadvantage relative to other investors in floating rate loans who do not follow such a policy, as the Fund may be limited in its available investments or unable to make accurate assessments related to certain investments.

Notwithstanding its intention to generally not receive material, nonpublic information with respect to its management of investments in floating rate loans, Janus Capital may from time to time come into possession of material, nonpublic information about the issuers of loans that may be held in a Fund’s holdings. To the extent required by applicable law, Janus Capital’s ability to trade in these loans for the account of a Fund could potentially be limited by its possession of such information, which could have an adverse effect on a Fund by, for example, preventing the Fund from selling a loan that is experiencing a material decline in value. In some instances, these trading restrictions could continue in effect for a substantial period of time.

The secondary market on which floating rate loans are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate loans and that there may be restrictions on their transfer. As a result, a Fund may be unable to sell assignments or participations at the desired time or may be able to sell only at a price less than fair market value. The secondary market may also be subject to irregular trading activity, wide price spreads, and extended trade settlement periods. With respect to below-investment grade or unrated securities, it also may be more difficult to value the securities because valuation may require more research, and elements of judgment may play a larger role in the valuation because there is less reliable, objective data available.

Other floating rate securities

The Funds may invest in other types of securities including, but not limited to, unsecured floating rate loans, subordinated or junior debt, corporate bonds, U.S. Government securities, mortgage-backed and other asset-backed securities, repurchase agreements, certain money market instruments, high-risk/high-yield bonds, and other instruments (including synthetic or hybrid) that pay interest at rates that adjust whenever a specified interest rate changes and/or resets on predetermined dates.

High-Yield/High-Risk Bonds

Within the parameters of its specific investment policies, each Fund may invest in bonds that are rated below investment grade (i.e., bonds rated BB+ or lower by Standard & Poor’s Ratings Service and Fitch, Inc., or Ba or lower by Moody’s Investors Service, Inc.). To the extent a Fund invests in high-yield/high-risk bonds, under normal circumstances, each of the Funds indicated will limit its investments in such bonds to 35% or less of its net assets (Janus Global Market Neutral Fund, Janus Global Real Estate Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus Overseas Fund, Janus Worldwide Fund, Janus Balanced Fund, Janus Enterprise Fund, Janus Forty Fund, Janus Fund, Janus Growth and Income Fund, Janus Research Fund, Janus Triton Fund, Janus Twenty Fund, Janus Venture Fund, and Perkins Global Value Fund) or 20% or less of its net assets (Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus International Equity Fund, and Janus Contrarian Fund).

Lower rated bonds involve a higher degree of credit risk, which is the risk that the issuer will not make interest or principal payments when due. In the event of an unanticipated default, a Fund would experience a reduction in its income, and could expect a decline in the market value of the bonds so affected.

A Fund may also invest in unrated bonds of foreign and domestic issuers. For the Funds subject to such limit, unrated bonds will be included in each Fund’s limit, as applicable, on investments in bonds rated below investment grade unless its

18  

portfolio managers and/or investment personnel deem such securities to be the equivalent of investment grade bonds. Unrated bonds, while not necessarily of lower quality than rated bonds, may not have as broad a market. Because of the size and perceived demand of the issue, among other factors, certain municipalities may not incur the costs of obtaining a rating. A Fund’s portfolio managers and/or investment personnel will analyze the creditworthiness of the issuer, as well as any financial institution or other party responsible for payments on the bond, in determining whether to purchase unrated municipal bonds.

The secondary market on which high-yield securities are traded is less liquid than the market for investment grade securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. Secondary markets for high-yield securities are less liquid than the market for investment grade securities; therefore, it may be more difficult to value the securities because valuation may require more research, and elements of judgment may play a larger role in the valuation because there is less reliable, objective data available.

Please refer to the “Explanation of Rating Categories” section of this SAI for a description of bond rating categories.

Defaulted Securities

A Fund may hold defaulted securities if the portfolio managers and/or investment personnel believe, based upon an analysis of the financial condition, results of operations, and economic outlook of an issuer, that there is potential for resumption of income payments and that the securities offer an unusual opportunity for capital appreciation. For the Funds subject to such limit, defaulted securities will be included in each Fund’s limit on investments in bonds rated below investment grade. Notwithstanding the portfolio managers’ and/or investment personnel’s belief about the resumption of income, however, the purchase of any security on which payment of interest or dividends is suspended involves a high degree of risk. Such risk includes, among other things, the following:

Financial and Market Risks. Investments in securities that are in default involve a high degree of financial and market risks that can result in substantial or, at times, even total losses. Issuers of defaulted securities may have substantial capital needs and may become involved in bankruptcy or reorganization proceedings. Among the problems involved in investments in such issuers is the fact that it may be difficult to obtain information about the condition of such issuers. The market prices of such securities also are subject to abrupt and erratic movements and above average price volatility, and the spread between the bid and asked prices of such securities may be greater than normally expected.

Disposition of Portfolio Securities. Although the Funds generally will purchase securities for which their portfolio managers and/or investment personnel expect an active market to be maintained, defaulted securities may be less actively traded than other securities, and it may be difficult to dispose of substantial holdings of such securities at prevailing market prices. The Funds will limit holdings of any such securities to amounts that the portfolio managers and/or investment personnel believe could be readily sold, and holdings of such securities would, in any event, be limited so as not to limit a Fund’s ability to readily dispose of securities to meet redemptions.

Other. Defaulted securities require active monitoring and may, at times, require participation in bankruptcy or receivership proceedings on behalf of the Funds.

Futures, Options, and Other Derivative Instruments

Certain Funds may invest in various types of derivatives, which may at times result in significant derivative exposure. A derivative is a financial instrument whose performance is derived from the performance of another asset. The Funds may invest in derivative instruments including, but not limited to: futures contracts, put options, call options, options on future contracts, options on foreign currencies, swaps, forward contracts, structured investments, and other equity-linked derivatives.

A Fund may use derivative instruments for hedging (to offset risks associated with an investment, currency exposure, or market conditions) or for speculative (to seek to enhance returns) purposes. When a Fund invests in a derivative for speculative purposes, the Fund will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. The Funds may not use any derivative to gain exposure to an asset or class of assets that they would be prohibited by their investment restrictions from purchasing directly. A Fund’s ability to use derivative instruments may also be limited by tax considerations. (See “Income Dividends, Capital Gains Distributions, and Tax Status.”)

Investments in derivatives in general are subject to market risks that may cause their prices to fluctuate over time. Investments in derivatives may not directly correlate with the price movements of the underlying instrument. As a result, the use of derivatives may expose a Fund to additional risks that it would not be subject to if it invested directly in the securities

  19

underlying those derivatives. The use of derivatives may result in larger losses or smaller gains than otherwise would be the case. Derivatives can be volatile and may involve significant risks, including:

Counterparty risk – the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to the Fund.

Currency risk – the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

Leverage risk – the risk associated with certain types of leveraged investments or trading strategies pursuant to which relatively small market movements may result in large changes in the value of an investment. A Fund creates leverage by using borrowed capital to increase the amount invested, or investing in instruments, including derivatives, where the investment loss can exceed the original amount invested. Certain investments or trading strategies that involve leverage can result in losses that greatly exceed the amount originally invested.

Liquidity risk – the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

Index risk – if the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, the Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

Derivatives may generally be traded over-the-counter (“OTC”) or on an exchange. Derivatives traded OTC, such as options and structured notes, are agreements that are individually negotiated between parties and can be tailored to meet a purchaser’s needs. OTC derivatives are not guaranteed by a clearing agency and may be subject to increased credit risk.

In an effort to mitigate credit risk associated with derivatives traded OTC, the Funds may enter into collateral agreements with certain counterparties whereby, subject to certain minimum exposure requirements, a Fund may require the counterparty to post collateral if the Fund has a net aggregate unrealized gain on all OTC derivative contracts with a particular counterparty. There is no guarantee that counterparty exposure is reduced and these arrangements are dependent on Janus Capital’s ability to establish and maintain appropriate systems and trading.

Futures Contracts. The Funds may enter into contracts for the purchase or sale for future delivery of equity securities, fixed-income securities, foreign currencies, commodities, and commodity-linked derivatives (to the extent permitted by the Fund and the Internal Revenue Code), or contracts based on financial indices, including indices of U.S. Government securities, foreign government securities, commodities, and equity or fixed-income securities. U.S. futures contracts are traded on exchanges which have been designated “contract markets” by the Commodity Futures Trading Commission (“CFTC”) and must be executed through a futures commission merchant (“FCM”) or brokerage firm, which are members of a relevant contract market. Through their clearing corporations, the exchanges guarantee performance of the contracts as between the clearing members of the exchange.

The buyer or seller of a futures contract is not required to deliver or pay for the underlying instrument unless the contract is held until the delivery date. However, both the buyer and seller are required to deposit “initial margin” for the benefit of the FCM when the contract is entered into. Initial margin deposits are equal to a percentage of the contract’s value, as set by the exchange on which the contract is traded, and currently are maintained in cash or certain other liquid assets held by the Funds. Initial margin payments are similar to good faith deposits or performance bonds. Unlike margin extended by a securities broker, initial margin payments do not constitute purchasing securities on margin for purposes of a Fund’s investment limitations. If the value of either party’s position declines, that party will be required to make additional “variation margin” payments for the benefit of the FCM to settle the change in value on a daily basis. The party that has a gain may be entitled to receive all or a portion of this amount. In the event of the bankruptcy of the FCM that holds margin on behalf of a Fund, that Fund may be entitled to return of margin owed to such Fund only in proportion to the amount received by the FCM’s other customers. Janus Capital or the subadviser will attempt to minimize the risk by careful monitoring of the creditworthiness of the FCMs with which the Funds do business.

The Funds may enter into futures contracts and related options as permitted under CFTC Rule 4.5. The Funds have claimed exclusion from the definition of the term “commodity pool operator” adopted by the CFTC and the National Futures

20  

Association, which regulate trading in the futures markets. Therefore, the Funds are not subject to commodity pool operator registration and regulation under the Commodity Exchange Act.

Although a Fund will segregate cash and liquid assets in an amount sufficient to cover its open futures obligations, the segregated assets would be available to that Fund immediately upon closing out the futures position; however, closing out open futures positions through customary settlement procedures could take several days. Because a Fund’s cash that may otherwise be invested would be held uninvested or invested in other liquid assets so long as the futures position remains open, such Fund’s return could be diminished due to the opportunity losses of foregoing other potential investments.

The Funds may enter into futures contracts to gain exposure to the stock market or other markets pending investment of cash balances or to meet liquidity needs. A Fund may also enter into futures contracts to protect itself from fluctuations in the value of individual securities, the securities markets generally, or interest rate fluctuations, without actually buying or selling the underlying debt or equity security. For example, if the Fund anticipates an increase in the price of stocks, and it intends to purchase stocks at a later time, that Fund could enter into a futures contract to purchase a stock index as a temporary substitute for stock purchases. If an increase in the market occurs that influences the stock index as anticipated, the value of the futures contracts will increase, thereby serving as a hedge against that Fund not participating in a market advance. This technique is sometimes known as an anticipatory hedge. A Fund may also use this technique with respect to an individual company’s stock. To the extent a Fund enters into futures contracts for this purpose, the segregated assets maintained to cover such Fund’s obligations with respect to the futures contracts will consist of liquid assets from its portfolio in an amount equal to the difference between the contract price and the aggregate value of the initial and variation margin payments made by that Fund with respect to the futures contracts. Conversely, if a Fund holds stocks and seeks to protect itself from a decrease in stock prices, the Fund might sell stock index futures contracts, thereby hoping to offset the potential decline in the value of its portfolio securities by a corresponding increase in the value of the futures contract position. Similarly, if a Fund holds an individual company’s stock and expects the price of that stock to decline, the Fund may sell a futures contract on that stock in hopes of offsetting the potential decline in the company’s stock price. A Fund could protect against a decline in stock prices by selling portfolio securities and investing in money market instruments, but the use of futures contracts enables it to maintain a defensive position without having to sell portfolio securities.

If a Fund owns interest rate sensitive securities and the portfolio managers and/or investment personnel expect interest rates to increase, that Fund may take a short position in interest rate futures contracts. Taking such a position would have much the same effect as that Fund selling such securities in its portfolio. If interest rates increase as anticipated, the value of the securities would decline, but the value of that Fund’s interest rate futures contract would increase, thereby keeping the NAV of that Fund from declining as much as it may have otherwise. If, on the other hand, the portfolio managers and/or investment personnel expect interest rates to decline, that Fund may take a long position in interest rate futures contracts in anticipation of later closing out the futures position and purchasing the securities. Although a Fund can accomplish similar results by buying securities with long maturities and selling securities with short maturities, given the greater liquidity of the futures market than the cash market, it may be possible to accomplish the same result more easily and more quickly by using futures contracts as an investment tool to reduce risk.

The ordinary spreads between prices in the cash and futures markets, due to differences in the nature of those markets, are subject to distortions. First, all participants in the futures market are subject to initial margin and variation margin requirements. Rather than meeting additional variation margin requirements, investors may close out futures contracts through offsetting transactions which could distort the normal price relationship between the cash and futures markets. Second, the liquidity of the futures market depends on participants entering into offsetting transactions rather than making or taking delivery of the instrument underlying a futures contract. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced and prices in the futures market distorted. Third, from the point of view of speculators, the margin deposit requirements in the futures market are less onerous than margin requirements in the securities market. Therefore, increased participation by speculators in the futures market may cause temporary price distortions. Due to the possibility of the foregoing distortions, a correct forecast of general price trends by the portfolio managers and/or investment personnel still may not result in a successful use of futures.

Futures contracts entail risks. There is no guarantee that derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. For example, if a Fund has hedged against the effects of a possible decrease in prices of securities held in its portfolio and prices increase instead, that Fund will lose part or all of the benefit of the increased value of these securities because of offsetting losses in its futures positions. This risk may be magnified for single stock futures transactions, as the portfolio managers and/or investment personnel must predict the direction of the price of an individual stock, as opposed to securities prices generally. In addition, if a Fund has insufficient

  21

cash, it may have to sell securities from its portfolio to meet daily variation margin requirements. Those sales may be, but will not necessarily be, at increased prices which reflect the rising market and may occur at a time when the sales are disadvantageous to such Fund.

The prices of futures contracts depend primarily on the value of their underlying instruments. Because there are a limited number of types of futures contracts, it is possible that the standardized futures contracts available to a Fund will not match exactly such Fund’s current or potential investments. A Fund may buy and sell futures contracts based on underlying instruments with different characteristics from the securities in which it typically invests – for example, by hedging investments in portfolio securities with a futures contract based on a broad index of securities – which involves a risk that the futures position will not correlate precisely with the performance of such Fund’s investments.

Futures prices can also diverge from the prices of their underlying instruments, even if the underlying instruments closely correlate with a Fund’s investments, such as with a single stock futures contract. Futures prices are affected by factors such as current and anticipated short-term interest rates, changes in volatility of the underlying instruments, and the time remaining until expiration of the contract. Those factors may affect securities prices differently from futures prices. Imperfect correlations between a Fund’s investments and its futures positions also may result from differing levels of demand in the futures markets and the securities markets, from structural differences in how futures and securities are traded, and from imposition of daily price fluctuation limits for futures contracts. A Fund may buy or sell futures contracts with a greater or lesser value than the securities it wishes to hedge or is considering purchasing in order to attempt to compensate for differences in historical volatility between the futures contract and the securities, although this may not be successful in all cases. If price changes in a Fund’s futures positions are poorly correlated with its other investments, its futures positions may fail to produce desired gains or result in losses that are not offset by the gains in that Fund’s other investments.

Because futures contracts are generally settled within a day from the date they are closed out, compared with a settlement period of three days for some types of securities, the futures markets can provide superior liquidity to the securities markets. Nevertheless, there is no assurance that a liquid secondary market will exist for any particular futures contract at any particular time. In addition, futures exchanges may establish daily price fluctuation limits for futures contracts and may halt trading if a contract’s price moves upward or downward more than the limit in a given day. On volatile trading days when the price fluctuation limit is reached, it may be impossible for a Fund to enter into new positions or close out existing positions. If the secondary market for a futures contract is not liquid because of price fluctuation limits or otherwise, a Fund may not be able to promptly liquidate unfavorable futures positions and potentially could be required to continue to hold a futures position until the delivery date, regardless of changes in its value. As a result, such Fund’s access to other assets held to cover its futures positions also could be impaired.

Options on Futures Contracts. The Funds may buy and write put and call options on futures contracts. A purchased option on a future gives a Fund the right (but not the obligation) to buy or sell a futures contract at a specified price on or before a specified date. The purchase of a call option on a futures contract is similar in some respects to the purchase of a call option on an individual security. As with other option transactions, securities will be segregated to cover applicable margin or segregation requirements on open futures contracts. Depending on the pricing of the option compared to either the price of the futures contract upon which it is based or the price of the underlying instrument, ownership of the option may or may not be less risky than ownership of the futures contract or the underlying instrument. As with the purchase of futures contracts, when a Fund is not fully invested, it may buy a call option on a futures contract to hedge against a market advance.

The writing of a call option on a futures contract constitutes a partial hedge against declining prices of a security, commodity, or foreign currency which is deliverable under, or of the index comprising, the futures contract. If the futures price at the expiration of the option is below the exercise price, a Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in that Fund’s portfolio holdings. The writing of a put option on a futures contract constitutes a partial hedge against increasing prices of a security, commodity, or foreign currency which is deliverable under, or of the index comprising, the futures contract. If the futures price at expiration of the option is higher than the exercise price, a Fund will retain the full amount of the option premium which provides a partial hedge against any increase in the price of securities which that Fund is considering buying. If a call or put option a Fund has written is exercised, such Fund will incur a loss which will be reduced by the amount of the premium it received. Depending on the degree of correlation between the change in the value of its portfolio securities and changes in the value of the futures positions, a Fund’s losses from existing options on futures may to some extent be reduced or increased by changes in the value of portfolio securities.

22  

The purchase of a put option on a futures contract is similar in some respects to the purchase of protective put options on portfolio securities. For example, a Fund may buy a put option on a futures contract to hedge its portfolio against the risk of falling prices or rising interest rates.

The amount of risk a Fund assumes when it buys an option on a futures contract is the premium paid for the option plus related transaction costs. In addition to the correlation risks discussed above, the purchase of an option also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the options bought.

Forward Contracts. A forward contract is an agreement between two parties in which one party is obligated to deliver a stated amount of a stated asset at a specified time in the future and the other party is obligated to pay a specified amount for the asset at the time of delivery. The Funds may enter into forward contracts to purchase and sell government securities, equity or income securities, foreign currencies, or other financial instruments. Currently, the Funds do not intend to invest in forward contracts other than forward currency contracts. Forward contracts generally are traded in an interbank market conducted directly between traders (usually large commercial banks) and their customers. Unlike futures contracts, which are standardized contracts, forward contracts can be specifically drawn to meet the needs of the parties that enter into them. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated exchange.

The following discussion summarizes the Funds’ principal uses of forward foreign currency exchange contracts (“forward currency contracts”). A Fund may enter into forward currency contracts with stated contract values of up to the value of that Fund’s assets. A forward currency contract is an obligation to buy or sell an amount of a specified currency for an agreed price (which may be in U.S. dollars or a foreign currency). A Fund may invest in forward currency contracts for nonhedging purposes such as seeking to enhance return. A Fund will exchange foreign currencies for U.S. dollars and for other foreign currencies in the normal course of business and may buy and sell currencies through forward currency contracts in order to fix a price for securities it has agreed to buy or sell (“transaction hedge”). A Fund also may hedge some or all of its investments denominated in a foreign currency or exposed to foreign currency fluctuations against a decline in the value of that currency relative to the U.S. dollar by entering into forward currency contracts to sell an amount of that currency (or a proxy currency whose performance is expected to replicate or exceed the performance of that currency relative to the U.S. dollar) approximating the value of some or all of its portfolio securities denominated in or exposed to that currency (“position hedge”) or by participating in options or futures contracts with respect to the currency. A Fund also may enter into a forward currency contract with respect to a currency where the Fund is considering the purchase or sale of investments denominated in that currency but has not yet selected the specific investments (“anticipatory hedge”). In any of these circumstances a Fund may, alternatively, enter into a forward currency contract to purchase or sell one foreign currency for a second currency that is expected to perform more favorably relative to the U.S. dollar if the portfolio managers and/or investment personnel believe there is a reasonable degree of correlation between movements in the two currencies (“cross-hedge”). In addition, certain Funds may cross-hedge their U.S. dollar exposure in order to achieve a representative weighted mix of the major currencies in their respective benchmark index and/or to cover an underweight country or region exposure in their portfolio.

These types of hedging minimize the effect of currency appreciation as well as depreciation, but do not eliminate fluctuations in the underlying U.S. dollar equivalent value of the proceeds of or rates of return on a Fund’s foreign currency denominated portfolio securities. The matching of the increase in value of a forward contract and the decline in the U.S. dollar equivalent value of the foreign currency denominated asset that is the subject of the hedge generally will not be precise. Shifting a Fund’s currency exposure from one foreign currency to another removes that Fund’s opportunity to profit from increases in the value of the original currency and involves a risk of increased losses to such Fund if the portfolio managers’ and/or investment personnel’s projection of future exchange rates is inaccurate. Proxy hedges and cross-hedges may protect against losses resulting from a decline in the hedged currency, but will cause a Fund to assume the risk of fluctuations in the value of the currency it purchases which may result in losses if the currency used to hedge does not perform similarly to the currency in which hedged securities are denominated. Unforeseen changes in currency prices may result in poorer overall performance for a Fund than if it had not entered into such contracts.

In general, the Funds cover outstanding forward currency contracts by maintaining liquid portfolio securities denominated in, or whose value is tied to, the currency underlying the forward contract or the currency being hedged. To the extent that a Fund is not able to cover its forward currency positions with underlying portfolio securities, the Fund’s custodian segregates cash or other liquid assets having a value equal to the aggregate amount of such Fund’s commitments under forward contracts entered into with respect to position hedges, cross-hedges, and anticipatory hedges. If the value of the securities used to cover a position or the value of segregated assets declines, a Fund will find alternative cover or segregate additional cash or other liquid assets on a daily basis so that the value of the covered and segregated assets will be equal to the amount

  23

of such Fund’s commitments with respect to such contracts. As an alternative to segregating assets, a Fund may buy call options permitting such Fund to buy the amount of foreign currency being hedged by a forward sale contract, or a Fund may buy put options permitting it to sell the amount of foreign currency subject to a forward buy contract.

While forward contracts are not currently regulated by the CFTC, the CFTC may in the future assert authority to regulate forward contracts. In such event, the Funds’ ability to utilize forward contracts may be restricted. In addition, a Fund may not always be able to enter into forward contracts at attractive prices and may be limited in its ability to use these contracts to hedge Fund assets.

Options on Foreign Currencies. The Funds may buy and write options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. For example, a decline in the U.S. dollar value of a foreign currency in which portfolio securities are denominated will reduce the U.S. dollar value of such securities, even if their value in the foreign currency remains constant. In order to protect against such diminutions in the value of portfolio securities, a Fund may buy put options on the foreign currency. If the value of the currency declines, such Fund will have the right to sell such currency for a fixed amount in U.S. dollars, thereby offsetting, in whole or in part, the adverse effect on its portfolio.

Conversely, when a rise in the U.S. dollar value of a currency in which securities to be acquired are denominated is projected, thereby increasing the cost of such securities, a Fund may buy call options on the foreign currency. The purchase of such options could offset, at least partially, the effects of the adverse movements in exchange rates. As in the case of other types of options, however, the benefit to a Fund from purchases of foreign currency options will be reduced by the amount of the premium and related transaction costs. In addition, if currency exchange rates do not move in the direction or to the extent projected, a Fund could sustain losses on transactions in foreign currency options that would require such Fund to forego a portion or all of the benefits of advantageous changes in those rates.

The Funds may also write options on foreign currencies. For example, to hedge against a potential decline in the U.S. dollar value of foreign currency denominated securities due to adverse fluctuations in exchange rates, a Fund could, instead of purchasing a put option, write a call option on the relevant currency. If the expected decline occurs, the option will most likely not be exercised, and the decline in value of portfolio securities will be offset by the amount of the premium received.

Similarly, instead of purchasing a call option to hedge against a potential increase in the U.S. dollar cost of securities to be acquired, a Fund could write a put option on the relevant currency which, if rates move in the manner projected, should expire unexercised and allow that Fund to hedge the increased cost up to the amount of the premium. As in the case of other types of options, however, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium. If exchange rates do not move in the expected direction, the option may be exercised, and a Fund would be required to buy or sell the underlying currency at a loss which may not be offset by the amount of the premium. Through the writing of options on foreign currencies, a Fund also may lose all or a portion of the benefits which might otherwise have been obtained from favorable movements in exchange rates.

The Funds may write covered call options on foreign currencies. A call option written on a foreign currency by a Fund is “covered” if that Fund owns the foreign currency underlying the call or has an absolute and immediate right to acquire that foreign currency without additional cash consideration (or for additional cash consideration held in a segregated account by its custodian) upon conversion or exchange of other foreign currencies held in its portfolio. A call option is also covered if a Fund has a call on the same foreign currency in the same principal amount as the call written if the exercise price of the call held: (i) is equal to or less than the exercise price of the call written or (ii) is greater than the exercise price of the call written, if the difference is maintained by such Fund in cash or other liquid assets in a segregated account with the Fund’s custodian.

The Funds also may write call options on foreign currencies for cross-hedging purposes. A call option on a foreign currency is for cross-hedging purposes if it is designed to provide a hedge against a decline due to an adverse change in the exchange rate in the U.S. dollar value of a security which a Fund owns or has the right to acquire and which is denominated in the currency underlying the option. Call options on foreign currencies which are entered into for cross-hedging purposes are not covered. However, in such circumstances, a Fund will collateralize the option by segregating cash or other liquid assets in an amount not less than the value of the underlying foreign currency in U.S. dollars marked-to-market daily.

Eurodollar Instruments. Each Fund may make investments in Eurodollar instruments. Eurodollar instruments are U.S. dollar-denominated futures contracts or options thereon which are linked to the LIBOR, although foreign currency denominated instruments are available from time to time. Eurodollar futures contracts enable purchasers to obtain a fixed

24  

rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund might use Eurodollar futures contracts and options thereon to hedge against changes in LIBOR, to which many interest rate swaps and fixed-income instruments are linked.

Additional Risks of Options on Foreign Currencies, Forward Contracts, and Foreign Instruments. Unlike transactions entered into by the Funds in futures contracts, options on foreign currencies and forward contracts are not traded on contract markets regulated by the CFTC or (with the exception of certain foreign currency options) by the SEC. To the contrary, such instruments are traded through financial institutions acting as market-makers, although foreign currency options are also traded on certain Exchanges, such as the Philadelphia Stock Exchange and the Chicago Board Options Exchange, subject to SEC regulation.

Similarly, options on currencies may be traded over-the-counter. In an OTC trading environment, many of the protections afforded to Exchange participants will not be available. For example, there are no daily price fluctuation limits, and adverse market movements could therefore continue to an unlimited extent over a period of time. Although the buyer of an option cannot lose more than the amount of the premium plus related transaction costs, this entire amount could be lost. Moreover, an option writer and a buyer or seller of futures or forward contracts could lose amounts substantially in excess of any premium received or initial margin or collateral posted due to the potential additional margin and collateral requirements associated with such positions.

Options on foreign currencies traded on Exchanges are within the jurisdiction of the SEC, as are other securities traded on Exchanges. As a result, many of the protections provided to traders on organized Exchanges will be available with respect to such transactions. In particular, all foreign currency option positions entered into on an Exchange are cleared and guaranteed by the Options Clearing Corporation (“OCC”), thereby reducing the risk of credit default. Further, a liquid secondary market in options traded on an Exchange may be more readily available than in the OTC market, potentially permitting a Fund to liquidate open positions at a profit prior to exercise or expiration or to limit losses in the event of adverse market movements.

The purchase and sale of exchange-traded foreign currency options, however, is subject to the risks of the availability of a liquid secondary market described above, as well as the risks regarding adverse market movements, margining of options written, the nature of the foreign currency market, possible intervention by governmental authorities, and the effects of other political and economic events. In addition, exchange-traded options on foreign currencies involve certain risks not presented by the OTC market. For example, exercise and settlement of such options must be made exclusively through the OCC, which has established banking relationships in applicable foreign countries for this purpose. As a result, the OCC may, if it determines that foreign governmental restrictions or taxes would prevent the orderly settlement of foreign currency option exercises, or would result in undue burdens on the OCC or its clearing member, impose special procedures on exercise and settlement, such as technical changes in the mechanics of delivery of currency, the fixing of dollar settlement prices, or prohibitions on exercise.

In addition, options on U.S. Government securities, futures contracts, options on futures contracts, forward contracts, and options on foreign currencies may be traded on foreign exchanges and OTC in foreign countries. Such transactions are subject to the risk of governmental actions affecting trading in or the prices of foreign currencies or securities. The value of such positions also could be adversely affected by: (i) other complex foreign political and economic factors; (ii) lesser availability than in the United States of data on which to make trading decisions; (iii) delays in a Fund’s ability to act upon economic events occurring in foreign markets during nonbusiness hours in the United States; (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States; and (v) low trading volume.

A Fund may from time to time participate on committees formed by creditors to negotiate with the management of financially troubled issuers of securities held by that Fund. Such participation may subject a Fund to expenses such as legal fees and may make that Fund an “insider” of the issuer for purposes of the federal securities laws, which may restrict that Fund’s ability to trade in or acquire additional positions in a particular security or other securities of the issuer when it might otherwise desire to do so. Participation by a Fund on such committees also may expose that Fund to potential liabilities under the federal bankruptcy laws or other laws governing the rights of creditors and debtors. A Fund would participate on such committees only when Janus Capital believes that such participation is necessary or desirable to enforce that Fund’s rights as a creditor or to protect the value of securities held by that Fund.

Options on Securities. In an effort to increase current income and to reduce fluctuations in NAV, the Funds may write covered and uncovered put and call options and buy put and call options on securities that are traded on U.S. and foreign

  25

securities exchanges and OTC. Examples of covering transactions include: (i) for a written put, selling short the underlying instrument at the same or higher price than the put’s exercise price; and (ii) for a written call, owning the underlying instrument. The Funds may write and buy options on the same types of securities that the Funds may purchase directly. The Funds may utilize American-style and European-style options. An American-style option is an option contract that can be exercised at any time between the time of purchase and the option’s expiration date. A European-style option is an option contract that can only be exercised on the option’s expiration date.

A Fund may cover its obligations on a put option by segregating cash or other liquid assets with the Fund’s custodian for a value equal to: (i) the full notional value of the put for physically settled options; or (ii) the in-the-money value of the put for cash settled options. A Fund may also cover its obligations on a put option by holding a put on the same security and in the same principal amount as the put written where the exercise price of the put held: (i) is equal to or greater than the exercise price of the put written; or (ii) is less than the exercise price of the put written if the difference is maintained by that Fund in cash or other liquid assets in a segregated account with its custodian. The premium paid by the buyer of an option will normally reflect, among other things, the relationship of the exercise price to the market price and the volatility of the underlying security, the remaining term of the option, supply and demand, and interest rates.

A Fund may cover its obligations on a call option by segregating cash or other liquid assets with the Fund’s custodian for a value equal to: (i) the full notional value of the call for physically settled options; or (ii) the in-the-money value of the call for cash settled options. A Fund may also cover its obligations on a written call option by (i) owning the underlying security covered by the call or having an absolute and immediate right to acquire that security without additional cash consideration (or for additional cash consideration held in a segregated account by the Fund’s custodian) upon conversion or exchange of other securities held in its portfolio; or (ii) holding a call on the same security and in the same principal amount as the call written where the exercise price of the call held: (a) is equal to or less than the exercise price of the call written; or (b) is greater than the exercise price of the call written if the difference is maintained by that Fund in cash or other liquid assets in a segregated account with its custodian.

A Fund would write a call option for hedging purposes, instead of writing a covered call option, when the premium to be received from the cross-hedge transaction would exceed that which would be received from writing a covered call option and the portfolio managers and/or investment personnel believe that writing the option would achieve the desired hedge.

The premium paid by the buyer of an option will normally reflect, among other things, the relationship of the exercise price to the market price and the volatility of the underlying security, the remaining term of the option, supply and demand, and interest rates.

The writer of an option may have no control over when the underlying securities must be sold, in the case of a call option, or bought, in the case of a put option, since with regard to certain options, the writer may be assigned an exercise notice at any time prior to the termination of the obligation. Whether or not an option expires unexercised, the writer retains the amount of the premium. This amount, of course, may, in the case of a covered call option, be offset by a decline in the market value of the underlying security during the option period. If a call option is exercised, the writer experiences a profit or loss from the sale of the underlying security. If a put option is exercised, the writer must fulfill the obligation to buy the underlying security at the exercise price, which will usually exceed the then market value of the underlying security.

The writer of an option that wishes to terminate its obligation may effect a “closing purchase transaction.” This is accomplished by buying an option of the same series as the option previously written. The effect of the purchase is that the writer’s position will be canceled by the clearing corporation. However, a writer may not effect a closing purchase transaction after being notified of the exercise of an option. Likewise, an investor who is the holder of an option may liquidate its position by effecting a “closing sale transaction.” This is accomplished by selling an option of the same series as the option previously bought. There is no guarantee that either a closing purchase or a closing sale transaction can be effected.

In the case of a written call option, effecting a closing transaction will permit a Fund to write another call option on the underlying security with either a different exercise price or expiration date or both. In the case of a written put option, such transaction will permit a Fund to write another put option to the extent that the exercise price is secured by deposited liquid assets. Effecting a closing transaction also will permit a Fund to use the cash or proceeds from the concurrent sale of any securities subject to the option for other investments. If a Fund desires to sell a particular security from its portfolio on which it has written a call option, such Fund will effect a closing transaction prior to or concurrent with the sale of the security.

26  

A Fund will realize a profit from a closing transaction if the price of the purchase transaction is less than the premium received from writing the option or the price received from a sale transaction is more than the premium paid to buy the option. A Fund will realize a loss from a closing transaction if the price of the purchase transaction is more than the premium received from writing the option or the price received from a sale transaction is less than the premium paid to buy the option. Because increases in the market price of a call option generally will reflect increases in the market price of the underlying security, any loss resulting from the repurchase of a call option is likely to be offset in whole or in part by appreciation of the underlying security owned by a Fund.

An option position may be closed out only where a secondary market for an option of the same series exists. If a secondary market does not exist, a Fund may not be able to effect closing transactions in particular options and that Fund would have to exercise the options in order to realize any profit. If a Fund is unable to effect a closing purchase transaction in a secondary market, it will not be able to sell the underlying security until the option expires or it delivers the underlying security upon exercise. The absence of a liquid secondary market may be due to the following: (i) insufficient trading interest in certain options; (ii) restrictions imposed by a national securities exchange (“Exchange”) on which the option is traded on opening or closing transactions or both; (iii) trading halts, suspensions, or other restrictions imposed with respect to particular classes or series of options or underlying securities; (iv) unusual or unforeseen circumstances that interrupt normal operations on an Exchange; (v) the facilities of an Exchange or of the OCC may not at all times be adequate to handle current trading volume; or (vi) one or more Exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that Exchange (or in that class or series of options) would cease to exist, although outstanding options on that Exchange that had been issued by the OCC as a result of trades on that Exchange would continue to be exercisable in accordance with their terms.

A Fund may write options in connection with buy-and-write transactions. In other words, a Fund may buy a security and then write a call option against that security. The exercise price of such call will depend upon the expected price movement of the underlying security. The exercise price of a call option may be below (“in-the-money”), equal to (“at-the-money”), or above (“out-of-the-money”) the current value of the underlying security at the time the option is written. Buy-and-write transactions using in-the-money call options may be used when it is expected that the price of the underlying security will remain flat or decline moderately during the option period. Buy-and-write transactions using at-the-money call options may be used when it is expected that the price of the underlying security will remain fixed or advance moderately during the option period. Buy-and-write transactions using out-of-the-money call options may be used when it is expected that the premiums received from writing the call option plus the appreciation in the market price of the underlying security up to the exercise price will be greater than the appreciation in the price of the underlying security alone. If the call options are exercised in such transactions, a Fund’s maximum gain will be the premium received by it for writing the option, adjusted upwards or downwards by the difference between that Fund’s purchase price of the security and the exercise price. If the options are not exercised and the price of the underlying security declines, the amount of such decline will be offset by the amount of premium received.

The writing of covered put options is similar in terms of risk and return characteristics to buy-and-write transactions. If the market price of the underlying security rises or otherwise is above the exercise price, the put option will expire worthless and a Fund’s gain will be limited to the premium received. If the market price of the underlying security declines or otherwise is below the exercise price, a Fund may elect to close the position or take delivery of the security at the exercise price and that Fund’s return will be the premium received from the put options minus the amount by which the market price of the security is below the exercise price.

A Fund may buy put options to hedge against a decline in the value of its portfolio. By using put options in this way, a Fund will reduce any profit it might otherwise have realized in the underlying security by the amount of the premium paid for the put option and by transaction costs.

A Fund may buy call options to hedge against an increase in the price of securities that it may buy in the future. The premium paid for the call option plus any transaction costs will reduce the benefit, if any, realized by such Fund upon exercise of the option, and, unless the price of the underlying security rises sufficiently, the option may expire worthless to that Fund.

A Fund may write straddles (combinations of put and call options on the same underlying security), which are generally a nonhedging technique used for purposes such as seeking to enhance return. Because combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out than individual

  27

options contracts. The straddle rules of the Internal Revenue Code require deferral of certain losses realized on positions of a straddle to the extent that a Fund has unrealized gains in offsetting positions at year end. The holding period of the securities comprising the straddle will be suspended until the straddle is terminated.

Options on Securities Indices. The Funds may also purchase and write exchange-listed and OTC put and call options on securities indices. A securities index measures the movement of a certain group of securities by assigning relative values to the securities. The index may fluctuate as a result of changes in the market values of the securities included in the index. Some securities index options are based on a broad market index, such as the New York Stock Exchange Composite Index, or a narrower market index such as the Standard & Poor’s 100. Indices may also be based on a particular industry, market segment, or certain currencies such as the U.S. Dollar Index or DXY Index.

Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount. Securities index options may be offset by entering into closing transactions as described above for securities options.

Options on Non-U.S. Securities Indices. The Funds may purchase and write put and call options on foreign securities indices listed on domestic and foreign securities exchanges. The Funds may also purchase and write OTC options on foreign securities indices.

The Funds may, to the extent allowed by federal and state securities laws, invest in options on non-U.S. securities indices instead of investing directly in individual non-U.S. securities. The Funds may also use foreign securities index options for bona fide hedging and non-hedging purposes.

Options on securities indices entail risks in addition to the risks of options on securities. The absence of a liquid secondary market to close out options positions on securities indices may be more likely to occur, although the Funds generally will only purchase or write such an option if Janus Capital or the subadviser, as applicable, believes the option can be closed out. Use of options on securities indices also entails the risk that trading in such options may be interrupted if trading in certain securities included in the index is interrupted. The Funds will not purchase such options unless Janus Capital or the subadviser, as applicable, believes the market is sufficiently developed such that the risk of trading in such options is no greater than the risk of trading in options on securities.

Price movements in a Fund’s portfolio may not correlate precisely with movements in the level of an index and, therefore, the use of options on indices cannot serve as a complete hedge. Because options on securities indices require settlement in cash, the portfolio managers and/or investment personnel may be forced to liquidate portfolio securities to meet settlement obligations. A Fund’s activities in index options may also be restricted by the requirements of the Internal Revenue Code for qualification as a regulated investment company.

In addition, the hours of trading for options on the securities indices may not conform to the hours during which the underlying securities are traded. To the extent that the option markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying securities markets that cannot be reflected in the option markets. It is impossible to predict the volume of trading that may exist in such options, and there can be no assurance that viable exchange markets will develop or exist.

Other Options. In addition to the option strategies described above and in the Prospectuses, a Fund may purchase and sell a variety of options with non-standard payout structures or other features (“exotic options”). Exotic options are traded OTC and typically have price movements that can vary markedly from simple put or call options. The risks associated with exotic options are that they cannot be as easily priced and may be subject to liquidity risk. While some exotic options have fairly active markets others are mostly thinly traded instruments. Some options are pure two-party transactions and may have no liquidity. Each Fund may treat such instruments as illiquid and will limit its investments in such instruments to no more than 15% of its net assets, when combined with all other illiquid investments of the Fund. A Fund may use exotic options to the extent that they are consistent with the Fund’s investment objective and investment policies, and applicable regulations.

28  

The Funds may purchase and sell exotic options that have values which are determined by the correlation of two or more underlying assets. These types of options include, but are not limited to, outperformance options, yield curve options, or other spread options.

Outperformance Option – An option that pays the holder the difference in the performance of two assets. The value of an outperformance option is based on the relative difference, i.e. the percentage outperformance of one underlying security or index compared to another. Outperformance options allow a Fund to gain leveraged exposure to the percentage price performance of one security or index over another. The holder of an outperformance option will only receive payment under the option contract if a designated underlying asset outperforms the other underlying asset. If outperformance does not occur, the holder will not receive payment. The option may expire worthless despite positive performance by the designated underlying asset. Outperformance options are typically cash settled and have European-style exercise provisions.

Yield Curve Options – An option whose value is based on the yield spread or yield differential between two securities. In contrast to other types of options, a yield curve option is based on the difference between the yields of designated securities, rather than the prices of the individual securities, and is settled through cash payments. Accordingly, a yield curve option is profitable to the holder if this differential widens (in the case of a call) or narrows (in the case of a put), regardless of whether the yields of the underlying securities increase or decrease.

Spread Option – A type of option that derives its value from the price differential between two or more assets, or the same asset at different times or places. Spread options can be written on all types of financial products including equities, bonds and currencies.

Swaps and Swap-Related Products. The Funds may enter into swap agreements or utilize swap-related products, including, but not limited to, total return swaps, equity swaps, interest rate swaps, caps, and floors (either on an asset-based or liability-based basis, depending upon whether it is hedging its assets or its liabilities). Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a day to more than one year. A Fund may enter into swap agreements in an attempt to gain exposure to the stocks making up an index of securities in a market without actually purchasing those stocks, or to hedge a position. The most significant factor in the performance of swap agreements is the change in value of the specific index, security, or currency, or other factors that determine the amounts of payments due to and from a Fund. The Funds will usually enter into interest rate swaps on a net basis (i.e., the two payment streams are netted out, with a Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of a Fund’s obligations over its entitlement with respect to each swap will be calculated on a daily basis, and an amount of cash or other liquid assets having an aggregate NAV at least equal to the accrued excess will be maintained in a segregated account by the Fund’s custodian. If a Fund enters into a swap on other than a net basis, it would maintain a segregated account in the full amount accrued on a daily basis of its obligations with respect to the swap.

Swap agreements entail the risk that a party will default on its payment obligations to the Fund. If there is a default by the other party to such a transaction, a Fund normally will have contractual remedies pursuant to the agreements related to the transaction. Swap agreements also bear the risk that a Fund will not be able to meet its obligation to the counterparty.

A Fund normally will not enter into any total return, equity, or interest rate swap, cap, or floor transaction unless the claims-paying ability of the other party thereto meets guidelines established by Janus Capital. Janus Capital’s guidelines may be adjusted in accordance with market conditions. Janus Capital or the subadviser, as applicable, will monitor the creditworthiness of all counterparties on an ongoing basis. Generally, parties that are rated in the highest short-term rating category by an NRSRO will meet Janus Capital’s guidelines. The ratings of NRSROs represent their opinions of the claims-paying ability of entities rated by them. NRSRO ratings are general and are not absolute standards of quality.

The swap market has grown substantially in recent years, with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. Janus Capital has determined that, as a result, the swap market has become relatively liquid. Caps and floors are more recent innovations for which standardized documentation has not yet been developed and, accordingly, they are less liquid than swaps. To the extent a Fund sells (i.e., writes) caps and floors, it will segregate cash or other liquid assets having an aggregate NAV at least equal to the full amount, accrued on a daily basis, of its obligations with respect to any caps or floors.

There is no limit on the amount of total return, equity, or interest rate swap transactions that may be entered into by a Fund. The use of equity swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Swap transactions may in some instances involve the delivery of securities or other underlying assets by a Fund or its counterparty to collateralize obligations under the swap. Under the

  29

documentation currently used in those markets, the risk of loss with respect to swaps is limited to the net amount of the payments that a Fund is contractually obligated to make. If the other party to a swap that is not collateralized defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. A Fund may buy and sell (i.e., write) caps and floors, without limitation, subject to the segregation requirement described above.

Another form of a swap agreement is the credit default swap. A Fund may enter into various types of credit default swap agreements (with values not to exceed 10% of the net assets of the Fund) for investment purposes and to add leverage to its portfolio. As the seller in a credit default swap contract, the Fund would be required to pay the par value (the “notional value”) (or other agreed-upon value) of a referenced debt obligation to the counterparty in the event of a default by a third party, such as a U.S. or foreign corporate issuer, on the debt obligation. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, that Fund would be subject to investment exposure on the notional value of the swap. The maximum potential amount of future payments (undiscounted) that the Fund as a seller could be required to make in a credit default transaction would be the notional amount of the agreement. A Fund may also purchase credit default swap contracts in order to hedge against the risk of default of debt securities held in its portfolio, in which case the Fund would function as the counterparty referenced in the preceding paragraph. Credit default swaps could result in losses if the Fund does not correctly evaluate the creditworthiness of the company or companies on which the credit default swap is based.

Credit default swap agreements may involve greater risks than if a Fund had invested in the reference obligation directly since, in addition to risks relating to the reference obligation, credit default swaps are subject to illiquidity risk, counterparty risk, and credit risk. A Fund will generally incur a greater degree of risk when it sells a credit default swap option than when it purchases a credit default swap. As a buyer of a credit default swap, the Fund may lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. As seller of a credit default swap, if a credit event were to occur, the value of any deliverable obligation received by the Fund, coupled with the upfront or periodic payments previously received, may be less than what it pays to the buyer, resulting in a loss of value to the Fund.

A Fund may invest in funded (notional value of contract paid up front) or unfunded (notional value only paid in case of default) credit default swaps that are based on an index of credit default swaps (“CDXs”) or other similarly structured products. CDXs are designed to track segments of the credit default swap market and provide investors with exposure to specific reference baskets of issuers of bonds or loans. These instruments have the potential to allow an investor to obtain the same investment exposure as an investor who invests in an individual credit default swap, but with the potential added benefit of diversification. The CDX reference baskets are normally priced daily and rebalanced every six months in conjunction with leading market makers in the credit industry. The liquidity of the market for CDXs is normally subject to liquidity in the secured loan and credit derivatives markets.

A Fund investing in CDXs is normally only permitted to take long positions in these instruments. A Fund holding a long position in CDXs typically receives income from principal or interest paid on the underlying securities. A Fund also normally indirectly bears its proportionate share of any expenses paid by a CDX in addition to the expenses of the Fund. By investing in CDXs, a Fund could be exposed to risks relating to, among other things, the reference obligation, illiquidity risk, counterparty risk, and credit risk.

Options on Swap Contracts. Certain funds may purchase or write covered and uncovered put and call options on swap contracts (“swaptions”). Swaption contracts grant the purchaser the right, but not the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. Entering into a swaption contract involves, to varying degrees, the elements of credit, market, and interest rate risk, associated with both option contracts and swap contracts.

Structured Investments. A structured investment is a security having a return tied to an underlying index or other security or asset class. Structured investments generally are individually negotiated agreements and may be traded over-the-counter. Structured investments are organized and operated to restructure the investment characteristics of the underlying security. This restructuring involves the deposit with or purchase by an entity, such as a corporation or trust, or specified instruments (such as commercial bank loans) and the issuance by that entity of one or more classes of securities (“structured securities”) backed by, or representing interests in, the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued structured securities to create securities with different investment characteristics, such as varying maturities, payment priorities, and interest rate provisions, and the extent of such payments made with respect to

30  

structured securities is dependent on the extent of the cash flow on the underlying instruments. Because structured securities typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Investments in structured securities are generally of a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities.

Investments in government and government-related restructured debt instruments are subject to special risks, including the inability or unwillingness to repay principal and interest, requests to reschedule or restructure outstanding debt, and requests to extend additional loan amounts. Structured investments include a wide variety of instruments which are also subject to special risk such as inverse floaters and collateralized debt obligations. Inverse floaters involve leverage which may magnify a Fund’s gains or losses. The risk of collateral debt obligations depends largely on the type of collateral securing the obligations. There is a risk that the collateral will not be adequate to make interest or other payments related to the debt obligation the collateral supports.

Structured instruments that are registered under the federal securities laws may be treated as liquid. In addition, many structured instruments may not be registered under the federal securities laws. In that event, a Fund’s ability to resell such a structured instrument may be more limited than its ability to resell other Fund securities. The Funds may treat such instruments as illiquid and will limit their investments in such instruments to no more than 15% of each Fund’s net assets, when combined with all other illiquid investments of each Fund.

PORTFOLIO TURNOVER

The portfolio turnover rate of a Fund is calculated by dividing the lesser of purchases or sales of portfolio securities (exclusive of purchases or sales of U.S. Government securities and all other securities whose maturities at the time of acquisition were one year or less) by the monthly average of the value of the portfolio securities owned by the Fund during the year. Proceeds from short sales and assets used to cover short positions undertaken are included in the amounts of securities sold and purchased, respectively, during the fiscal year. A 100% portfolio turnover rate would occur, for example, if all of the securities held by a Fund were replaced once during the fiscal year. A Fund cannot accurately predict its turnover rate. Variations in portfolio turnover rates shown may be due to market conditions, changes in the size of a Fund, fluctuating volume of shareholder purchase and redemption orders, the nature of a Fund’s investments, and the investment style and/or outlook of the portfolio managers and/or investment personnel. A Fund’s portfolio turnover rate may be higher when a Fund finds it necessary to significantly change its portfolio to adopt a temporary defensive position or respond to economic or market events. Higher levels of portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover may offset gains in Fund performance. The following tables summarize the portfolio turnover rates for the Funds for the fiscal years or periods noted.

PORTFOLIO HOLDINGS DISCLOSURE POLICIES AND PROCEDURES

The Mutual Fund Holdings Disclosure Policies and Procedures adopted by Janus Capital and all mutual funds managed within the Janus fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes policies and procedures with respect to disclosure of portfolio holdings.

•  Full Holdings. Each Fund is required to disclose its complete holdings in the quarterly holdings report on Form N-Q within 60 days of the end of each fiscal quarter, and in the annual report and semiannual report to Fund shareholders. These reports (i) are available on the SEC’s website at http://www.sec.gov; (ii) may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. (information on the Public Reference Room may be obtained by calling 1-800-SEC-0330); and (iii) are available without charge, upon request, by calling a Janus representative at 1-800-525-0020 (toll free). Portfolio holdings (excluding derivatives, short positions, and other investment positions), consisting of at least the names of the holdings, are generally available on a calendar quarter-end basis with a 30-day lag. Holdings are generally posted approximately two business days thereafter under Full Holdings for each Fund at janus.com/info (or under each Fund’s Holdings & Details tab at janus.com/allfunds if you hold Class D Shares).

Each Fund may provide, upon request, historical full holdings on a monthly basis for periods prior to the previous quarter-end subject to a written confidentiality agreement.

•  Top Holdings. Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag.

•  Other Information. Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top performance contributors/detractors (consisting of security names in alphabetical order), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag and on a calendar quarter-end basis with a 15-day lag. Top performance contributors/detractors provided at calendar quarter-end may include the percentage of contribution/detraction to Fund performance.

Full portfolio holdings will remain available on the Janus websites at least until a Form N-CSR or Form N-Q is filed with the SEC for the period that includes the date as of which the website information is current. Funds disclose their short positions, if applicable, only to the extent required in regulatory reports. Janus Capital may exclude from publication all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus funds.

The Janus funds’ Trustees, officers, and primary service providers, including investment advisers identified in this SAI, distributors, administrators, transfer agents, custodians, and their respective personnel, may receive or have access to nonpublic portfolio holdings information. In addition, third parties, including but not limited to those that provide services to the Janus funds, Janus Capital, and its affiliates, such as trade execution measurement systems providers, independent pricing services, proxy voting service providers, the funds’ insurers, computer systems service providers, lenders, counsel, accountants/auditors, and rating and ranking organizations may also receive or have access to nonpublic portfolio holdings information. Other recipients of nonpublic portfolio holdings information may include, but may not be limited to, third parties such as consultants, data aggregators, and asset allocation services which calculate information derived from holdings for use by Janus Capital, and which supply their analyses (but not the holdings themselves) to their clients. Such parties, either by agreement or by virtue of their duties, are required to maintain confidentiality with respect to such nonpublic portfolio holdings.

Nonpublic portfolio holdings information may be disclosed to certain third parties upon a good faith determination made by Janus Capital’s Chief Compliance Officer or Ethics Committee that a Janus fund has a legitimate business purpose for such disclosure and the recipient agrees to maintain confidentiality. Preapproval by the Chief Compliance Officer or Ethics Committee is not required for certain routine service providers and in response to regulatory, administrative, and judicial requirements. The Chief Compliance Officer reports to the Janus funds’ Trustees regarding material compliance matters with respect to the portfolio holdings disclosure policies and procedures.

Under extraordinary circumstances, Janus Capital’s Chief Investment Officer(s) or their delegates have the authority to waive one or more provisions of, or make exceptions to, the Mutual Fund Holdings Disclosure Policies and Procedures when in the best interest of the Janus funds and when such waiver or exception is consistent with federal securities laws and applicable fiduciary duties. The frequency with which portfolio holdings are disclosed, as well as the lag time associated with such disclosure, may vary as deemed appropriate under the circumstances. All waivers and exceptions involving any of the Janus funds shall be pre-approved by the Chief Compliance Officer or a designee.

Investment adviser and subadvisers

INVESTMENT ADVISER – JANUS CAPITAL MANAGEMENT LLC

As stated in the Prospectuses, each Fund has an Investment Advisory Agreement with Janus Capital Management LLC, 151 Detroit Street, Denver, Colorado 80206-4805. Janus Capital is a direct subsidiary of Janus Capital Group Inc. (“JCGI”), a publicly traded company with principal operations in financial asset management businesses. JCGI owns approximately 95% of Janus Capital, with the remaining 5% held by Janus Management Holdings Corporation.

Each Fund’s Advisory Agreement continues in effect from year to year so long as such continuance is approved annually by a majority of the Funds’ Trustees who are not parties to the Advisory Agreements or “interested persons” (as defined by the 1940 Act) of any such party (the “Independent Trustees”), and by either a majority of the outstanding voting shares of each Fund or the Trustees of the Funds. Each Advisory Agreement: (i) may be terminated without the payment of any penalty by a Fund or Janus Capital on 60 days’ written notice; (ii) terminates automatically in the event of its assignment; and (iii) generally, may not be amended without the approval by vote of a majority of the Trustees of the affected Fund, including a majority of the Independent Trustees and, to the extent required by the 1940 Act, the vote of a majority of the outstanding voting securities of that Fund.

Each Advisory Agreement provides that Janus Capital will furnish continuous advice and recommendations concerning the Funds’ investments, provide office space for the Funds, and certain other advisory-related services. Each Fund pays custodian fees and expenses, any brokerage commissions and dealer spreads, and other expenses in connection with the execution of portfolio transactions, legal and audit expenses, interest and taxes, a portion of trade or other investment company dues and expenses, expenses of shareholders’ meetings, mailing of prospectuses, statements of additional information, and reports to shareholders, fees and expenses of all Fund Trustees, other costs of complying with applicable laws regulating the sale of Fund shares, compensation to the Funds’ transfer agent, and other costs, including shareholder servicing costs. As discussed in this section, Janus Capital has delegated certain management duties for certain Funds to Janus Singapore and Perkins pursuant to subadvisory agreements (“Sub-Advisory Agreements”) between Janus Capital and each subadviser.

Janus Capital also serves as administrator and is authorized to perform, or cause others to perform, the administration services necessary for the operation of the Funds, including, but not limited to, NAV determination, portfolio accounting, recordkeeping, blue sky registration and monitoring services, preparation of prospectuses and other Fund documents, and other services for which the Funds reimburse Janus Capital for its out-of-pocket costs. Each Fund also pays for the salaries, fees, and expenses of certain Janus Capital employees and Fund officers, with respect to certain specified administration functions they perform on behalf of the Funds. Administration costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services Janus Capital (or any subadviser) provides to each Fund. Some expenses related to compensation payable to the Funds’ Chief Compliance Officer and compliance staff are shared with the Funds.

Many of these costs vary from year to year which can make it difficult to predict the total impact to your Fund’s expense ratio, in particular during times of declining asset values of a Fund. Certain costs may be waived and/or reimbursed by Janus Capital to the Funds pursuant to expense limitation agreements with a Fund.

A discussion regarding the basis for the Trustees’ approval of the Funds’ Investment Advisory Agreements and Sub-Advisory Agreements (as applicable) is included in the Funds’ annual or semiannual report to shareholders. You can request the Funds’ annual or semiannual reports (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus representative at 1-877-335-2687 (or 1-800-525-3713 if you hold Class D Shares). The reports are also available, free of charge, at janus.com/info (or janus.com/reports if you hold Class D Shares).

The Funds pay a monthly investment advisory fee to Janus Capital for its services. The fee is based on the average daily net assets of each Fund for Funds with an annual fixed-rate fee, and is calculated at the annual rate. The detail for Funds with this fee structure is shown below under “Average Daily Net Assets of the Fund.” Funds that pay a fee that may adjust up or down based on the Fund’s performance relative to its benchmark index over the performance measurement period have “N/A” in the “Average Daily Net Assets of the Fund” column below. The following table also reflects the Funds’ contractual fixed-rate investment advisory fee rate for Funds with an annual fee based on average daily net assets and the “base fee” rate prior to any performance fee adjustment for Funds that have a performance fee structure.

Under the performance-based fee structure, the investment advisory fee paid to Janus Capital by each Fund consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period generally is the previous 36 months, although no Performance Adjustment will be made until the performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund; or 18 months for Janus Forty Fund and Janus Twenty Fund) (“Initial Performance Measurement Period”); and accordingly, only the Fund’s Base Fee Rate applies for the Initial Performance Measurement Period. When the performance-based fee structure has been in effect for at least the Initial Performance Measurement Period, but less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment advisory fee is paid monthly in arrears.

The Performance Adjustment may result in an increase or decrease in the investment advisory fee paid by a Fund, depending upon the investment performance of the Fund relative to its benchmark index over the performance measurement period. No Performance Adjustment is applied unless the difference between the Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s performance relative to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses, whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation

  39

ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

With the exception of Janus Twenty Fund, the investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. For performance measurement periods prior to July 6, 2009, certain Funds calculated their Performance Adjustment by comparing the performance of Class T Shares (formerly named Class J Shares) against the investment record of each Fund’s respective benchmark index. For periods beginning July 6, 2009, the investment performance of each Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After Janus Capital determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares, or Class T Shares (formerly named Class J Shares) as the case may be, against the cumulative investment record of that Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund.

As noted, for certain Funds, effective July 6, 2009, the investment performance of the Fund’s load-waived Class A Shares is used to calculate the Performance Adjustment. However, because the Fund’s Performance Adjustment is based upon a rolling 36-month performance measurement period, calculations based on the Fund’s load-waived Class A Shares will not be fully implemented for 36 months after July 6, 2009. During this transition period, the Fund’s performance will be compared to a blended investment performance record that includes the Fund’s Class T Shares (formerly named Class J Shares) performance (the prior share class used for performance calculations) for the portion of the performance measurement period prior to July 6, 2009, and the Fund’s load-waived Class A Shares for the remainder of the period. At the conclusion of the transition period, the Fund’s Class T Shares will be eliminated from the Performance Adjustment calculation, and the calculation will be based solely upon the Fund’s load-waived Class A Shares.

Because Janus Twenty Fund does not offer Class A Shares, the investment performance of the Fund’s Class T Shares (formerly named Class J Shares) will be used for purposes of calculating the Fund’s Performance Adjustment. After Janus Capital determines whether Janus Twenty Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s Class T Shares against the cumulative investment record of the Fund’s benchmark index, Janus Capital will apply the same Performance Adjustment (positive or negative) across any other class of shares of Janus Twenty Fund.

The Trustees may determine that a class of shares of a Fund other than Class A Shares (Class T Shares for Janus Twenty Fund) is the most appropriate for use in calculating the Performance Adjustment. If a different class of shares is substituted in calculating the Performance Adjustment, the use of that successor class of shares may apply to the entire performance measurement period so long as the successor class was outstanding at the beginning of such period. If the successor class of shares was not outstanding for all or a portion of the performance measurement period, it may only be used in calculating that portion of the Performance Adjustment attributable to the period during which the successor class was outstanding, and any prior portion of the performance measurement period would be calculated using the class of shares previously designated. Any change to the class of shares used to calculate the Performance Adjustment is subject to applicable law.

The Trustees may from time to time determine that another securities index for a Fund is a more appropriate benchmark index for purposes of evaluating the performance of that Fund. In that event, the Trustees may approve the substitution of a successor index for the Fund’s benchmark index. However, the calculation of the Performance Adjustment for any portion of the performance measurement period prior to the adoption of the successor index will still be based upon the Fund’s performance compared to its former benchmark index. Any change to a particular Fund’s benchmark index for purposes of calculating the Performance Adjustment is subject to applicable law. It is currently the position of the staff of the SEC (the “Staff”) that any changes to a Fund’s benchmark index will require shareholder approval. If there is a change in the Staff’s position, the Trustees intend to notify shareholders of such change in position at such time as the Trustees may determine that a change in a Fund’s benchmark index is appropriate.

Under certain circumstances, the Trustees may, without the prior approval of Fund shareholders, implement changes to the performance fee structure of a Fund as discussed above, subject to applicable law.

Effective July 1, 2010, the FTSE EPRA/NAREIT Global Index became Janus Global Real Estate Fund’s benchmark index for purposes of measuring the Fund’s performance and calculating the Performance Adjustment to the investment advisory fee paid by the Fund to Janus Capital. However, because the Fund’s Performance Adjustment is based upon a rolling 36-month performance measurement period, comparisons to the FTSE EPRA/NAREIT Global Index will not be fully implemented until 36 months after July 1, 2010. During this transition period, the Fund’s returns will be compared to a blended index return

40  

that reflects a measurement of the Fund’s performance relative to the FTSE EPRA/NAREIT Developed Index, the Fund’s prior benchmark index, for the portion of the performance measurement period prior to July 1, 2010, and a measurement of the Fund’s performance relative to the performance of the FTSE EPRA/NAREIT Global Index for periods following July 1, 2010. For periods through July 1, 2013, the performance measurement period will reflect one less month of Performance Adjustment to the FTSE EPRA/NAREIT Developed Index. At the conclusion of the transition period, the FTSE EPRA/NAREIT Developed Index will be eliminated from the Performance Adjustment calculation, and the calculation will include only the Fund’s performance relative to the FTSE EPRA NAREIT Global Index.

It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it will depend on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

If the average daily net assets of a Fund remain constant during a 36-month performance measurement period, current net assets will be the same as average net assets over the performance measurement period and the maximum Performance Adjustment will be equivalent to 0.15% of current net assets. When current net assets vary from net assets over the 36-month performance measurement period, the Performance Adjustment, as a percentage of current assets, may vary significantly, including at a rate more or less than 0.15%, depending upon whether the net assets of the Fund had been increasing or decreasing (and the amount of such increase or decrease) during the performance measurement period. Note that if net assets for a Fund were increasing during the performance measurement period, the total performance fee paid, measured in dollars, would be more than if that Fund had not increased its net assets during the performance measurement period.

Suppose, for example, that the Performance Adjustment was being computed after the assets of a Fund had been shrinking. Assume its monthly Base Fee Rate was 1/12^th of 0.60% of average daily net assets during the previous month. Assume also that average daily net assets during the 36-month performance measurement period were $500 million, but that average daily net assets during the preceding month were just $200 million.

The Base Fee Rate would be computed as follows:

$200 million x 0.60% ¸ 12 = $100,000

If the Fund outperformed or underperformed its benchmark index by an amount which triggered the maximum Performance Adjustment, the Performance Adjustment would be computed as follows:

$500 million x 0.15% ¸ 12 = $62,500, which is approximately 1/12^th of 0.375% of $200 million.

If the Fund had outperformed its benchmark index, the total advisory fee rate for that month would be $162,500, which is approximately 1/12^th of 0.975% of $200 million.

If the Fund had underperformed its benchmark index, the total advisory fee rate for that month would be $37,500, which is approximately 1/12^th of 0.225% of $200 million.

Therefore, the total advisory fee rate for that month, as a percentage of average net assets during the preceding month, would be approximately 1/12^th of 0.975% in the case of outperformance, or approximately 1/12^th of 0.225% in the case of underperformance. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

By contrast, the Performance Adjustment would be a smaller percentage of current assets if the net assets of the Fund were increasing during the performance measurement period. Suppose, for example, that the Performance Adjustment was being computed after the assets of a Fund had been growing. Assume its average daily net assets during the 36-month performance measurement period were $500 million, but that average daily net assets during the preceding month were $800 million.

The Base Fee Rate would be computed as follows:

$800 million x 0.60% ¸ 12 = $400,000

If the Fund outperformed or underperformed its benchmark index by an amount which triggered the maximum Performance Adjustment, the Performance Adjustment would be computed as follows:

$500 million x 0.15% ¸ 12 = $62,500, which is approximately 1/12^th of 0.094% of $800 million.

  41

If the Fund had outperformed its benchmark index, the total advisory fee rate for that month would be $462,500, which is approximately 1/12^th of 0.694% of $800 million.

If the Fund had underperformed its benchmark index, the total advisory fee rate for that month would be $337,500, which is approximately 1/12^th of 0.506% of $800 million.

Therefore, the total advisory fee rate for that month, as a percentage of average net assets during the preceding month, would be approximately 1/12^th of 0.694% in the case of outperformance, or approximately 1/12^th of 0.506% in the case of underperformance.

The Base Fee Rate for each Fund and the Fund’s benchmark index used for purposes of calculating the Performance Adjustment are shown in the following table:

The following hypothetical examples illustrate the application of the Performance Adjustment for each Fund. The examples assume that the average daily net assets of the Fund remain constant during a 36-month performance measurement period. The Performance Adjustment would be a smaller percentage of current assets if the net assets of the Fund were increasing during the performance measurement period, and a greater percentage of current assets if the net assets of the Fund were decreasing during the performance measurement period. All numbers in the examples are rounded to the nearest hundredth percent. The net assets of each Fund as of the fiscal year ended September 30, 2011 are shown below.

Fund Name	Net Assets (000s)
Janus Global Research Fund	$	236,460
Janus Worldwide Fund	$	1,853,555
Janus Contrarian Fund	$	2,447,893
Janus Research Fund	$	2,933,749

Examples: Janus Global Research Fund

The monthly maximum positive or negative Performance Adjustment of 1/12th of 0.15% of average net assets during the prior 36 months occurs if the Fund outperforms or underperforms its benchmark index by 6.00% over the same period. The Performance Adjustment is made in even increments for every 0.50% difference in the investment performance of the Fund’s Class A Shares (waiving the upfront sales load) compared to the cumulative investment record of the MSCI World Growth Index.

Example 1: Fund Outperforms Its Benchmark Index By 6.00%

If the Fund has outperformed the MSCI World Growth Index by 6.00% during the preceding 36 months, the Fund would calculate the investment advisory fee as follows:

		Total Advisory Fee Rate
Base Fee Rate	Performance Adjustment Rate	for that Month
1/12th of 0.64%	1/12th of 0.15%	1/12th of 0.79%

Example 2: Fund Performance Tracks Its Benchmark Index

If the Fund performance has tracked the performance of the MSCI World Growth Index during the preceding 36 months, the Fund would calculate the investment advisory fee as follows:

		Total Advisory Fee Rate
Base Fee Rate	Performance Adjustment Rate	for that Month

SUBADVISERS

Janus Capital has entered into Sub-Advisory Agreements on behalf of Janus Asia Equity Fund and Perkins Global Value Fund.

JANUS CAPITAL SINGAPORE PTE. LIMITED

Janus Capital has entered into a Sub-Advisory Agreement with Janus Capital Singapore Pte. Limited, #36-02 AXA Tower, 8 Shenton Way, Singapore 068811, on behalf of Janus Asia Equity Fund.

Janus Singapore has been in the investment advisory business since 2011. Janus Singapore also serves as subadviser to offshore investment funds. Janus Singapore is a wholly-owned subsidiary of Janus Capital.

Under the Sub-Advisory Agreement between Janus Capital and Janus Singapore, Janus Singapore is responsible for the day-to-day investment operations of Janus Asia Equity Fund. Investments will be acquired, held, disposed of or loaned, consistent with the investment objectives, policies and restrictions established by the Trustees and set forth in the Trust’s registration statement. Janus Singapore: (i) manages the investment operations of the Fund; (ii) keeps Janus Capital fully informed as to the valuation of assets of the Fund, its condition, investment decisions and considerations; (iii) maintains all books and records required under federal securities law relating to day-to-day portfolio management of the Fund; (iv) performs certain limited related administrative functions; and (v) provides the Trustees and Janus Capital with economic, operational, and investment data and reports. The Sub-Advisory Agreement provides that Janus Singapore shall not be liable for any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission taken with respect to the Fund, except for willful malfeasance, bad faith, or gross negligence in the performance of its duties, or by reason of reckless disregard of its obligations and duties under the Sub-Advisory Agreement and except to the extent otherwise provided by law.

Under the Sub-Advisory Agreement, Janus Capital pays Janus Singapore a fee equal to 50% of the advisory fee payable by Janus Asia Equity Fund to Janus Capital (calculated after any applicable performance fee adjustment, fee waivers, and expense reimbursements).

  53

The Sub-Advisory Agreement with Janus Singapore will continue in effect for an initial term through February 2013, and then from year to year thereafter if such continuation is specifically approved at least annually by the Trustees or by vote of a majority of the outstanding shares of the Fund, and in either case by vote of a majority of the Independent Trustees of the Fund. The Sub-Advisory Agreement is subject to termination at any time by Janus Capital or Janus Singapore by giving 90 days’ advance written notice to the other party (Janus Singapore shall allow up to an additional 90 days at the request of Janus Capital or the Trust in order to find a replacement for Janus Singapore) or by Janus Capital or the Trust without advance notice if Janus Singapore is unable to discharge its duties and obligations. The Fund’s Sub-Advisory Agreement terminates automatically in the event of the assignment or termination of the Fund’s Investment Advisory Agreement.

PERFORMANCE-BASED SUBADVISORY FEE

Janus Asia Equity Fund has an investment advisory fee rate that adjusts up or down based upon the Fund’s performance of the Fund’s Class A Shares (waiving the upfront sales load) relative to the cumulative performance of its benchmark index over the performance measurement period. Any performance adjustment will commence August 1, 2012. Until that time, only the fixed rate applies. In accordance with the Sub-Advisory Agreement, Janus Singapore receives a fee from Janus Capital equal to 50% of the advisory fee payable to Janus Capital from the Fund (net of any applicable performance fee adjustments, reimbursement of expenses incurred, or fees waived by Janus Capital).

PERKINS INVESTMENT MANAGEMENT LLC

As a result of shareholder approval of an amended investment advisory agreement effective July 1, 2010, Janus Capital has entered into a Sub-Advisory Agreement with Perkins Investment Management LLC, 311 S. Wacker Drive, Suite 6000, Chicago, Illinois 60606, on behalf of Perkins Global Value Fund.

Perkins and its predecessors have been in the investment advisory business since 1984. Perkins also serves as investment adviser or subadviser to separately managed accounts and other registered investment companies. Janus Capital owns approximately 78% of Perkins.

Under the Sub-Advisory Agreement between Janus Capital and Perkins, Perkins is responsible for the day-to-day investment operations of Perkins Global Value Fund. Investments will be acquired, held, disposed of or loaned, consistent with the investment objectives, policies and restrictions established by the Trustees and set forth in the Trust’s registration statement. Perkins: (i) manages the investment operations of the Fund; (ii) keeps Janus Capital fully informed as to the valuation of assets of the Fund, its condition, investment decisions and considerations; (iii) maintains all books and records required under federal securities law relating to day-to-day portfolio management of the Fund; (iv) performs certain limited related administrative functions; and (v) provides the Trustees and Janus Capital with economic, operational, and investment data and reports. The Sub-Advisory Agreement provides that Perkins shall not be liable for any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission taken with respect to the Fund, except for willful malfeasance, bad faith, or gross negligence in the performance of its duties, or by reason of reckless disregard of its obligations and duties under the Sub-Advisory Agreement and except to the extent otherwise provided by law.

Under the Sub-Advisory Agreement, Janus Capital pays Perkins a fee equal to 50% of the advisory fee payable by Perkins Global Value Fund to Janus Capital (calculated after any applicable performance fee adjustment).

The Sub-Advisory Agreement with Perkins will continue in effect from year to year if such continuation is specifically approved at least annually by the Trustees or by vote of a majority of the outstanding shares of the Fund, and in either case by vote of a majority of the Independent Trustees of the Fund. The Sub-Advisory Agreement is subject to termination at any time by Janus Capital or Perkins by giving 90 days’ advance written notice to the other party (Perkins shall allow up to an additional 90 days at the request of Janus Capital or the Trust in order to find a replacement for Perkins) or by Janus Capital or the Trust without advance notice if Perkins is unable to discharge its duties and obligations. The Fund’s Sub-Advisory Agreement terminates automatically in the event of the assignment or termination of the Fund’s Investment Advisory Agreement.

PERFORMANCE-BASED SUB-ADVISORY FEE

As a result of shareholder approval of Perkins Global Value Fund’s amended investment advisory agreement between Janus Capital and the Trust, on behalf of the Fund, effective July 1, 2010, the subadvisory fee paid to Perkins is a fee that adjusts up or down based upon the performance of the Fund’s Class A Shares (waiving the upfront sales load) relative to the MSCI World Index^sm, the Fund’s benchmark index. Any performance adjustment commenced July 1, 2011 for Perkins Global Value

54  

Fund. Until that time, only the fixed rate applied. In accordance with the Sub-Advisory Agreement, Perkins receives a fee from Janus Capital equal to 50% of the advisory fee payable to Janus Capital from the Fund (net of any applicable performance fee adjustment).

PAYMENTS TO FINANCIAL INTERMEDIARIES BY JANUS CAPITAL OR ITS AFFILIATES

In addition to payments made under 12b-1 plans, Janus Capital and its affiliates also may make payments out of their own assets to selected broker-dealer firms or other financial intermediaries that sell Class A and Class C Shares of Janus funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Janus Capital and its affiliates consider a number of factors in making payments to financial intermediaries. Criteria may include, but are not limited to, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness to cooperate with Janus Capital’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors and their weightings may differ from one intermediary to another and may change from time to time. As of the date of this SAI, the broker-dealer firms with which Janus Capital or its affiliates have agreements or are currently negotiating agreements to make payments out of their own assets related to the acquisition or retention of shareholders for Class A and Class C Shares are AIG Advisor Group, Inc. and its broker-dealer subsidiaries; Ameriprise Financial Services, Inc.; Citigroup Global Markets Inc.; Lincoln Financial Advisors Corporation; LPL Financial Corporation; Merrill Lynch, Pierce, Fenner & Smith Incorporated; Morgan Stanley Smith Barney, LLC; Oppenheimer & Co., Inc.; Raymond James & Associates, Inc.; Raymond James Financial

  55

Services, Inc.; UBS Financial Services Inc.; and Wells Fargo Advisors, LLC. These fees may be in addition to fees paid from a Fund’s assets to them or other financial intermediaries. Any additions, modifications, or deletions to the broker-dealer firms identified that have occurred since that date are not reflected.

In addition, for all share classes (with the exception of Class D Shares), Janus Capital, Janus Distributors LLC (“Janus Distributors”), or their affiliates may pay, from their own assets, brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries’ fees for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services in connection with investments in the Janus funds. These fees are in addition to any fees that may be paid from a Fund’s assets to these financial intermediaries. Janus Capital or its affiliates may have numerous agreements to make payments to financial institutions which perform recordkeeping or other administrative services with respect to shareholder accounts. Contact your financial intermediary if you wish to determine whether it receives such payments.

Janus Capital or its affiliates may also share certain marketing expenses with, or pay for, or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for financial intermediaries to raise awareness of the Funds. Janus Capital or its affiliates may make payments to participate in intermediary marketing support programs which may provide Janus Capital or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus funds available to their customers.

The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus funds’ shares over sales of another Janus funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach Janus Capital to request that Janus Capital make contributions to certain charitable organizations. In these cases, Janus Capital’s contribution may result in the financial intermediary, or its salespersons, recommending Janus funds over other mutual funds (or non-mutual fund investments).

The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you.

ADDITIONAL INFORMATION ABOUT JANUS CAPITAL AND THE SUBADVISERS

Janus Capital acts as subadviser for a number of private-label mutual funds and provides separate account advisory services for institutional accounts. Janus Capital may also manage its own proprietary accounts, as well as other pooled investment vehicles, such as hedge funds. Janus Capital has a fiduciary responsibility to manage all client accounts in a fair and equitable manner. As such, investment decisions for each account managed by Janus Capital, including the Funds, are made independently from those for any other account that is or may in the future become managed by Janus Capital or its affiliates. If, however, a number of accounts managed by Janus Capital are contemporaneously engaged in the purchase or sale of the same security, the orders may be aggregated and/or the transactions may be averaged as to price and allocated to each account in accordance with allocation procedures adopted by Janus Capital. Partial fills for the accounts of two or more portfolio managers and/or investment personnel will be allocated pro rata under procedures adopted by Janus Capital. Circumstances may arise under which Janus Capital may determine that, although it may be desirable and/or suitable that a particular

56  

security or other investment be purchased or sold for more than one account, there exists a limited supply or demand for the security or other investment. Janus Capital seeks to allocate the opportunity to purchase or sell that security or other investment among accounts on an equitable basis by taking into consideration factors including, but not limited to, size of the portfolio, concentration of holdings, investment objectives and guidelines, purchase costs, and cash availability. Janus Capital, however, cannot assure equality of allocations among all its accounts, nor can it assure that the opportunity to purchase or sell a security or other investment will be proportionally allocated among accounts according to any particular or predetermined standards or criteria. In some cases, these allocation procedures may adversely affect the price paid or received by an account or the size of the position obtained or liquidated for an account. In others, however, the accounts’ ability to participate in volume transactions may produce better executions and prices for the accounts.

With respect to allocations of initial public offerings of equity securities or syndicate offerings of bonds (each a “Primary Offering”), under Primary Offering allocation procedures adopted by Janus Capital and Perkins, an account may participate in a Primary Offering if the portfolio managers and/or investment personnel believe the Primary Offering is an appropriate investment based on the account’s investment restrictions, risk profile, asset composition, and/or cash levels. For equity securities, these Primary Offering allocation procedures generally require that all shares purchased in a Primary Offering be allocated on a pro rata basis to all participating accounts based upon the total assets of each account. For syndicated bond offerings, the Primary Offering procedures generally require that all bonds purchased be allocated on a pro rata basis to all participating accounts within the same investment strategy (as opposed to pro rata across all participating accounts).

Janus Capital is permitted to adjust its allocation procedures to address fractional shares, odd lots, or minimum issue sizes and has the discretion to deviate from its allocation procedures in certain circumstances. For example, additional securities may be allocated to the portfolio managers and/or investment personnel who are instrumental in originating or developing an investment opportunity or to comply with the portfolio managers’ and/or investment personnel’s request to ensure that their accounts receive sufficient securities to satisfy specialized investment objectives. Participation in Primary Offerings may impact performance. In particular, the allocation of securities may have the unintended consequence of having a greater impact (positive or negative) on the performance of one or more accounts compared to other accounts.

Janus Capital manages long and short portfolios. The simultaneous management of long and short portfolios creates potential conflicts of interest in fund management and creates potential risks such as the risk that short sale activity could adversely affect the market value of long positions in one or more Janus funds (and vice versa), the risk arising from the sequential orders in long and short positions, and the risks associated with the trade desk receiving opposing orders in the same security at the same time.

Janus Capital has adopted procedures that it believes are reasonably designed to mitigate these and other potential conflicts and risks. Among other things, Janus Capital has trade allocation procedures in place as previously described. In addition, procedures prohibit a portfolio manager from executing a short sale on a security held long in any other portfolio that he or she manages but not held long in the account the manager is placing the short in. Note this does not prohibit shorting against the box. The procedures also require approvals of Janus Capital senior management in other situations that raise potential conflicts of interest, as well as periodic monitoring of long and short trading activity of the Janus funds and accounts.

Janus Singapore, the subadviser for Janus Asia Equity Fund, and Perkins, the subadviser for Perkins Global Value Fund, may buy and sell securities or engage in other investments on behalf of multiple clients, including the Funds. Janus Singapore and Perkins seek to allocate trades among their clients on an equitable basis, taking into consideration such factors as the size of the client’s portfolio, concentration of holdings, investment objectives and guidelines, purchase costs, and cash availability.

The Funds and other funds advised by Janus Capital or its affiliates may also transfer daily uninvested cash balances into one or more joint trading accounts. Assets in the joint trading accounts are invested in money market instruments and the proceeds are allocated to the participating funds on a pro rata basis.

Pursuant to the provisions of the 1940 Act, Janus mutual funds may participate in an affiliated or non-affiliated cash sweep program. In the cash sweep program, uninvested cash balances of Janus funds may be used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles. All Janus funds are eligible to participate in the cash sweep program (the “Investing Funds”). As adviser, Janus Capital has an inherent conflict of interest because of its fiduciary duties to the affiliated money market funds or cash management pooled investment vehicles and the Investing Funds. In addition, Janus Capital receives an investment advisory fee for managing the cash management vehicle used for its securities lending program, but it may not receive a fee for managing certain other affiliated cash management vehicles, and

  57

therefore may have an incentive to allocate preferred investment opportunities to investment vehicles for which it is receiving a fee.

Each account managed by Janus Capital or the subadvisers has its own investment objective and policies and is managed accordingly by the respective portfolio managers and/or investment personnel. As a result, from time to time, two or more different managed accounts may pursue divergent investment strategies with respect to investments or categories of investments.

The officers and Trustees of the Janus funds may also serve as officers and Trustees of the Janus “funds of funds,” which are funds that primarily invest in other Janus mutual funds. Conflicts may arise as the officers and Trustees seek to fulfill their fiduciary responsibilities to both the Janus funds of funds and the other Janus mutual funds. The Trustees intend to address any such conflicts as deemed appropriate.

Janus Ethics Rules

Janus Capital, Janus Singapore, Perkins, and Janus Distributors currently have in place Ethics Rules, which are comprised of the Personal Trading Code of Ethics, Gift and Entertainment Policy, and Outside Employment Policy. The Ethics Rules are designed to ensure Janus Capital, Janus Singapore, Perkins, and Janus Distributors personnel: (i) observe applicable legal (including compliance with applicable federal securities laws) and ethical standards in the performance of their duties; (ii) at all times place the interests of the Fund shareholders first; (iii) disclose all actual or potential conflicts; (iv) adhere to the highest standards of loyalty, candor, and care in all matters relating to the Fund shareholders; (v) conduct all personal trading, including transactions in the Funds and other securities, consistent with the Ethics Rules and in such a manner as to avoid any actual or potential conflict of interest or any abuse of their position of trust and responsibility; and (vi) do not use any material nonpublic information in securities trading. The Ethics Rules are on file with and available from the SEC through the SEC website at http://www.sec.gov.

Under the Personal Trading Code of Ethics (the “Code of Ethics”), all Janus Capital, Janus Singapore, Perkins, and Janus Distributors personnel, as well as the Trustees and Officers of the Funds, are required to conduct their personal investment activities in a manner that Janus Capital believes is not detrimental to the Funds. In addition, Janus Capital, Janus Singapore, Perkins, and Janus Distributors personnel are not permitted to transact in securities held by the Funds for their personal accounts except under circumstances specified in the Code of Ethics. All personnel of Janus Capital, Janus Singapore, Perkins, Janus Distributors, and the Funds, as well as certain other designated employees deemed to have access to current trading information, are required to pre-clear all transactions in securities not otherwise exempt. Requests for trading authorization will be denied when, among other reasons, the proposed personal transaction would be contrary to the provisions of the Code of Ethics.

In addition to the pre-clearance requirement described above, the Code of Ethics subjects such personnel to various trading restrictions and reporting obligations. All reportable transactions are reviewed for compliance with the Code of Ethics and under certain circumstances Janus Capital, Janus Singapore, Perkins, and Janus Distributors personnel may be required to forfeit profits made from personal trading.

PROXY VOTING POLICIES AND PROCEDURES

Each Fund’s Trustees have delegated to Janus Capital or the Fund’s subadviser, as applicable, the authority to vote all proxies relating to such Fund’s portfolio securities in accordance with Janus Capital’s or the applicable subadviser’s own policies and procedures. Summaries of Janus Capital’s and the applicable subadviser’s policies and procedures are available without charge: (i) upon request, by calling 1-800-525-0020; (ii) on the Funds’ website at janus.com/proxyvoting; and (iii) on the SEC’s website at http://www.sec.gov.

A complete copy of Janus Capital’s proxy voting policies and procedures, including specific guidelines, is available at janus.com/proxyvoting.

Each Fund’s proxy voting record for the one-year period ending each June 30th is available, free of charge, through janus.com/proxyvoting and from the SEC through the SEC website at http://www.sec.gov.

JANUS CAPITAL MANAGEMENT LLC
PROXY VOTING SUMMARY FOR MUTUAL FUNDS

Janus Capital seeks to vote proxies in the best interest of its shareholders and without regard to any other Janus Capital relationship (business or otherwise). Janus Capital will not accept direction as to how to vote individual proxies for which it

58  

has voting responsibility from any other person or organization other than the research and information provided by its independent proxy voting service (“Proxy Voting Service”), subject to specific provisions in a client’s account documentation related to exception voting.

Proxy Voting Procedures

Janus Capital has developed proxy voting guidelines (the “Janus Guidelines”) that outline how Janus Capital generally votes proxies on securities held by the portfolios Janus Capital manages. The Janus Guidelines, which include recommendations on most major corporate issues, have been developed by the Janus Proxy Voting Committee (the “Proxy Voting Committee”) in consultation with Janus Capital’s portfolio managers. In creating proxy voting recommendations, the Proxy Voting Committee analyzes proxy proposals, from the Proxy Voting Service, from the prior year and evaluates whether those proposals would adversely or beneficially affect shareholders’ interests. The Proxy Voting Committee also reviews policy rationale provided by the Proxy Voting Service related to voting recommendations for the upcoming proxy season. Once the Proxy Voting Committee establishes its recommendations and revises the Janus Guidelines, they are distributed to Janus Capital’s portfolio managers for review and implementation. While the Proxy Voting Committee sets the Janus Guidelines and serves as a resource for Janus Capital’s portfolio managers, it does not have proxy voting authority for any proprietary or nonproprietary mutual fund. Janus Capital’s portfolio managers are responsible for proxy votes on securities they own in the portfolios they manage. The portfolio managers do not have the right to vote on securities while they are being lent; however, the portfolio managers may attempt to call back the loan and vote the proxy if time permits. Most portfolio managers vote consistently with the Janus Guidelines; however, a portfolio manager may choose to vote differently than the Janus Guidelines. Additionally, Janus Capital has engaged the Proxy Voting Service to assist in the voting of proxies. The Proxy Voting Service also provides research and recommendations on proxy issues.

The Proxy Voting Committee’s oversight responsibilities include monitoring for, and resolving, material conflicts of interest with respect to proxy voting. Janus Capital believes that application of the Janus Guidelines to vote mutual fund proxies should, in most cases, adequately address any possible conflicts of interest since the Janus Guidelines are predetermined. On a quarterly basis, the Proxy Voting Committee reviews records of any votes that were cast differently than the Janus Guidelines and the related rationales for such votes. Additionally, and in instances where a portfolio manager proposes to vote a proxy inconsistent with the Janus Guidelines and a potential conflict is identified, the Proxy Voting Committee will review the proxy votes in order to determine whether a portfolio manager’s voting rationale appears reasonable. If the Proxy Voting Committee does not agree that a portfolio manager’s rationale is reasonable, the Proxy Voting Committee will refer the matter to Janus Capital’s Chief Investment Officer(s) (or Director of Research).

As discussed above, the Proxy Voting Committee has developed the Janus Guidelines for use in voting proxies. Below is a summary of some of the Janus Guidelines.

Board of Directors Issues

Janus Capital: (i) will generally vote in favor of slates of director candidates that are comprised of a majority of independent directors; (ii) will generally vote in favor of proposals to increase the minimum number of independent directors; and (iii) will generally oppose non-independent directors who serve on the audit, compensation, and/or nominating committees of the board.

Auditor Issues

Janus Capital will generally oppose proposals asking for approval of auditors that have a financial interest in or association with the company and are therefore not independent.

Executive Compensation Issues

Janus Capital reviews executive compensation plans on a case-by-case basis using research provided by the Proxy Voting Service. The research is designed to estimate the total cost of a proposed plan. If the proposed cost is above an allowable cap as identified by the Proxy Voting Service, the proposed equity-based compensation plan will generally be opposed. In addition, proposals regarding the re-pricing of underwater options (stock options in which the price the employee is contracted to buy shares is higher than the current market price) and the issuance of reload options (stock options that are automatically granted if outstanding stock options are exercised during a window period) will generally be opposed.

General Corporate Issues

Janus Capital: (i) will generally oppose proposals regarding supermajority voting rights (for example, to approve acquisitions or mergers); (ii) will generally oppose proposals for different classes of stock with different voting rights; and (iii) will

  59

generally oppose proposals seeking to implement measures designed to prevent or obstruct corporate takeovers, unless such measures are designed primarily as a short-term means to protect a tax benefit. Janus Capital will review proposals relating to mergers, acquisitions, tender offers, and other similar actions on a case-by-case basis.

Shareholder Proposals

If a shareholder proposal is specifically addressed by the Janus Guidelines, Janus Capital will generally vote pursuant to that Janus Guideline. Janus Capital will generally abstain from voting shareholder proposals that are social, moral, or ethical in nature or place arbitrary constraints on the board or management of a company. Janus Capital will solicit additional research from its Proxy Voting Service for proposals outside the scope of the Janus Guidelines.

JANUS CAPITAL SINGAPORE PTE. LIMITED
PROXY VOTING SUMMARY FOR MUTUAL FUNDS

Janus Singapore seeks to vote proxies in the best interest of shareholders and without regard to any other Janus Singapore relationship (business or otherwise). Janus Singapore will not accept direction as to how to vote individual proxies for which it has voting responsibility from any other person or organization other than the research and information provided by the Proxy Voting Service, subject to specific provisions in a client’s account documentation related to exception voting.

Proxy Voting Procedures

Janus Singapore has developed proxy voting guidelines (the “Guidelines”) that outline how Janus Singapore generally votes proxies on securities held by the portfolios Janus Singapore manages. The Guidelines, which include recommendations on most major corporate issues, have been developed by the Proxy Voting Committee. The portfolio managers are responsible for proxy votes on securities they own in the portfolios they manage. The portfolio managers do not have the right to vote on securities while they are being lent; however, the portfolio managers may attempt to call back the loan and vote the proxy if time permits. Most portfolio managers vote consistently with the Guidelines; however, a portfolio manager may choose to vote differently than the Guidelines. Additionally, Janus Singapore has engaged the Proxy Voting Service to assist in the voting of proxies. The Proxy Voting Service also provides research and recommendations on proxy issues.

The Proxy Voting Committee’s oversight responsibilities include monitoring for, and resolving, material conflicts of interest with respect to proxy voting. Janus Singapore believes that application of the Guidelines to vote mutual fund proxies should, in most cases, adequately address any possible conflicts of interest since the Guidelines are predetermined. On a quarterly basis, the Proxy Voting Committee reviews records of any votes that were cast differently than the Guidelines and the related rationales for such votes. Additionally, and in instances where a portfolio manager proposes to vote a proxy inconsistent with the Guidelines and a potential conflict is identified, the Proxy Voting Committee will review the proxy votes in order to determine whether a portfolio manager’s voting rationale appears reasonable. If the Proxy Voting Committee does not agree that a portfolio manager’s rationale is reasonable, the Proxy Voting Committee will refer the matter to the Chief Investment Officer(s) (or Director of Research).

PERKINS INVESTMENT MANAGEMENT LLC
PROXY VOTING SUMMARY FOR MUTUAL FUNDS

Perkins seeks to vote proxies in the best interest of its shareholders and without regard to any other Perkins relationship (business or otherwise). Perkins will not accept direction as to how to vote individual proxies for which it has voting responsibility from any other person or organization other than the research and information provided by the Proxy Voting Service, subject to specific provisions in a client’s account documentation related to exception voting.

Proxy Voting Procedures

Perkins has developed proxy voting guidelines (the “Perkins Guidelines”) that outline how Perkins generally votes proxies on securities held by the portfolios Perkins manages. The Perkins Guidelines, which include recommendations on most major corporate issues, have been developed by the Perkins Proxy Voting Committee. Perkins portfolio managers are responsible for proxy votes on securities they own in the portfolios they manage. Most portfolio managers vote consistently with the Perkins Guidelines; however, a portfolio manager may choose to vote differently than the Perkins Guidelines. Perkins has delegated the administration of its proxy voting to Janus Capital. Janus Capital, on Perkins’ behalf, has engaged the Proxy Voting Service to assist in the voting of proxies. The Proxy Voting Service also provides research and recommendations on proxy issues.

The role of the Perkins Proxy Voting Committee is to develop the Perkins Guidelines. The Perkins Proxy Voting Committee also serves as a resource to portfolio management with respect to proxy voting and oversees the proxy voting process. The Perkins Proxy Voting Committee’s oversight responsibilities include monitoring for and resolving material conflicts of interest with respect to proxy voting. Perkins believes that application of the Perkins Guidelines to vote mutual fund proxies should, in most cases, adequately address any possible conflicts of interest since the Perkins Guidelines are predetermined. However, for proxy votes that are inconsistent with the Perkins Guidelines, the Perkins Proxy Voting Committee will review the proxy votes in order to determine whether the portfolio manager’s voting rationale appears reasonable. If the Perkins Proxy Voting Committee does not agree that the portfolio manager’s rationale is reasonable, the Perkins Proxy Voting Committee will refer the matter to the Chief Investment Officer(s) (or the Director of Research).

Custodian, transfer agent, and certain affiliations

State Street Bank and Trust Company (“State Street”), P.O. Box 0351, Boston, Massachusetts 02117-0351 is the custodian of the domestic securities and cash of the Funds and an affiliated cash management pooled vehicle. State Street is the designated Foreign Custody Manager (as the term is defined in Rule 17f-5 under the 1940 Act) of the Funds’ securities and cash held outside the United States. The Funds’ Trustees have delegated to State Street certain responsibilities for such assets, as permitted by Rule 17f-5. State Street and the foreign subcustodians selected by it hold the Funds’ assets in safekeeping and collect and remit the income thereon, subject to the instructions of each Fund.

Janus Services LLC (“Janus Services”), 151 Detroit Street, Denver, Colorado 80206-4805, a wholly-owned subsidiary of Janus Capital, is the Funds’ transfer agent. In addition, Janus Services provides or arranges for the provision of certain other administrative services including, but not limited to, recordkeeping, accounting, order processing, and other shareholder services for the Funds.

Certain, but not all, intermediaries may charge administrative fees to investors in Class A Shares, Class C Shares, and Class I Shares for administrative services provided on behalf of such investors. These administrative fees are paid by the Class A Shares, Class C Shares, and Class I Shares of the Funds to Janus Services, which uses such fees to reimburse intermediaries. Consistent with the Transfer Agency Agreement between Janus Services and the Funds, Janus Services may negotiate the level, structure, and/or terms of the administrative fees with intermediaries requiring such fees on behalf of the Funds. Janus Capital and its affiliates benefit from an increase in assets that may result from such relationships.

Class D Shares of the Funds pay an annual administrative services fee of 0.12% of net assets. These administrative services fees are paid by Class D Shares of each Fund for shareholder services provided by Janus Services.

Janus Services receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class R Shares, Class S Shares, and Class T Shares of each Fund for providing or procuring administrative services to investors in Class R Shares, Class S Shares, and Class T Shares of the Funds. Janus Services expects to use all or a significant portion of this fee to compensate retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries for providing these services. Janus Services or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to Class R Shares, Class S Shares, and Class T Shares of each Fund.

Services provided by these financial intermediaries may include, but are not limited to, recordkeeping, subaccounting, order processing, providing order confirmations, periodic statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, answering inquires regarding accounts, and other administrative services. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with Janus.

For the fiscal years or periods noted, the total amounts paid by Class D Shares, Class R Shares, Class S Shares, and Class T Shares of the Funds to Janus Services for administrative services are summarized below. For Class R Shares, Class S Shares, and Class T Shares, Janus Services pays out all or substantially all of the amount reflected as compensation to broker-dealers and service providers.

Janus Services is compensated for its services related to Class D Shares, and receives reimbursement for its out-of-pocket costs on all other share classes. Included in out-of-pocket expenses are the expenses Janus Services incurs for serving as transfer agent and providing servicing to shareholders.

Through Janus Services, the Funds pay DST Systems, Inc. (“DST”) fees for the use of DST’s shareholder accounting system, as well as for certain broker-controlled accounts and closed accounts. These fees are in addition to any administrative services fees paid to Janus Services. The Funds also use and pay for DST systems to track and process contingent deferred sales charges. These fees are only charged to classes of the Funds with contingent deferred sales charges, as applicable.

Janus Distributors, 151 Detroit Street, Denver, Colorado 80206-4805, a wholly-owned subsidiary of Janus Capital, is the principal underwriter for the Funds. Janus Distributors is registered as a broker-dealer under the Securities Exchange Act of 1934 and is a member of the Financial Industry Regulatory Authority, Inc. Janus Distributors acts as the agent of the Funds in connection with the sale of their Shares in all states in which such Shares are registered and in which Janus Distributors is qualified as a broker-dealer. Under the Distribution Agreement, Janus Distributors continuously offers each Fund’s Shares and accepts orders at NAV per share of the relevant class. The cash-compensation amount or rate at which Janus Distributors’ registered representatives are paid for sales of products may differ based on a type of fund or a specific trust or the distribution channel or platform. The receipt of (or prospect of receiving) compensation described above may provide an incentive for a registered representative to favor sales of funds, or certain share classes of a fund, for which they receive a higher compensation amount or rate. You should consider these arrangements when evaluating any recommendations of your registered representative.

Portfolio transactions and brokerage

Janus Capital places all portfolio transactions of the Funds, except for Janus Asia Equity Fund and Perkins Global Value Fund. With respect to Janus Asia Equity Fund, Janus Capital places all portfolio transactions solely upon Janus Singapore’s direction. With respect to Perkins Global Value Fund, Janus Capital places all portfolio transactions solely upon Perkins’ direction. Janus Capital, Janus Singapore, and Perkins have a policy of seeking to obtain the “best execution” of all portfolio transactions (the best net prices under the circumstances based upon a number of factors including and subject to the factors discussed below) provided that Janus Capital, Janus Singapore, and Perkins may occasionally pay higher commissions for research services as described below. The Funds may trade foreign securities in foreign countries because the best available market for these securities is often on foreign exchanges. In transactions on foreign stock exchanges, brokers’ commissions are frequently fixed and are often higher than in the United States, where commissions are negotiated.

Janus Capital considers a number of factors in seeking best execution in selecting brokers and dealers and in negotiating commissions on agency transactions. In seeking best execution on trades for Funds subadvised by Janus Singapore or Perkins, Janus Capital acts on behalf of and in consultation with each subadviser. Those factors include, but are not limited to: Janus Capital’s, Janus Singapore’s, and Perkins’ knowledge of currently available negotiated commission rates or prices of securities currently available and other current transaction costs; the nature of the security being traded; the size and type of the transaction; the nature and character of the markets for the security to be purchased or sold; the desired timing of the trade; the activity existing and expected in the market for the particular security; confidentiality, including trade anonymity; liquidity; the quality of the execution, clearance, and settlement services; financial stability of the broker or dealer; the existence of actual or apparent operational problems of any broker or dealer; rebates of commissions by a broker to a Fund or to a third party service provider to the Fund to pay Fund expenses; and the value of research products or services provided by brokers. In recognition of the value of the foregoing factors, and as permitted by Section 28(e) of the Securities Exchange Act of 1934, as amended, Janus Capital may place portfolio transactions with a broker or dealer with whom it has negotiated a commission that is in excess of the commission another broker or dealer would have charged for effecting that transaction if Janus Capital (or Janus Capital acting on behalf of and in consultation with each subadviser) determines in good faith that such amount of commission was reasonable in light of the value of the brokerage and research services provided by such broker or dealer viewed in terms of either that particular transaction or of the overall responsibilities of Janus Capital or the subadviser, as applicable. To constitute eligible “research services,” such services must qualify as “advice,” “analyses,” or “reports.” To determine that a service constitutes research services, Janus Capital or the subadviser, as applicable, must conclude that it reflects the “expression of reasoning or knowledge” relating to the value of securities, advisability of effecting transactions in securities or analyses, or reports concerning issuers, securities, economic factors, investment strategies, or the performance of accounts. To constitute eligible “brokerage services,” such services must effect securities transactions and functions incidental thereto, and include clearance, settlement, and the related custody services. Additionally, brokerage services have been interpreted to include services relating to the execution of securities transactions. Research received from brokers or dealers is supplemental to Janus Capital’s and each subadviser’s own research efforts. Because Janus Capital and the subadvisers receive a benefit from research they receive from broker-dealers, Janus Capital and the subadvisers may have an incentive to continue to use those broker-dealers to effect transactions. Janus Capital and the subadvisers do not consider a broker-dealer’s sale of Fund shares when choosing a broker-dealer to effect transactions.

“Cross trades,” in which one Janus Capital account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. Janus Capital and the funds’ Trustees have adopted compliance procedures that provide that any transactions between the Fund and another Janus-advised account are to be made at an independent current market price, as required by law. There is also a potential conflict of interest when cross trades involve a Janus fund that has substantial ownership by Janus Capital. At times, Janus Capital may have a controlling interest of a fund involved in a cross trade.

Janus Global Market Neutral Fund intends to maintain a prime brokerage arrangement to facilitate short sale transactions. A prime broker may provide, and the current prime broker of the Fund is expected to provide, services and products to Janus Capital in connection with the lending, short selling facilities, and related services the prime broker provides to the Fund and other clients. These services may include, without limitation, electronic interfaces, software and various reports in connection with short sale activity. As a result of these services and products, Janus Capital may have an incentive to use the prime broker to effect transactions for the Fund or to accept less favorable pricing for prime brokerage services (including interest and similar charges on short positions).

Janus Capital, Janus Singapore, and Perkins do not guarantee any broker the placement of a predetermined amount of securities transactions in return for the research or brokerage services it provides. Janus Capital, Janus Singapore, and Perkins do, however, have internal procedures for allocating transactions in a manner consistent with their execution policies to brokers that they have identified as providing research, research-related products or services, or execution-related services of a particular benefit to their clients. Janus Capital, Janus Singapore, and Perkins have entered into client commission agreements (“CCAs”) with certain broker-dealers under which the broker-dealers may use a portion of their commissions to pay third parties or other broker-dealers that provide Janus Capital, Janus Singapore, and Perkins with research or brokerage services, as permitted under Section 28(e) of the Securities and Exchange Act of 1934. CCAs allow Janus Capital, Janus Singapore, and Perkins to direct broker-dealers to pool commissions that are generated from orders executed at that broker-dealer, and then periodically direct the broker-dealer to pay third parties or other broker-dealers for research or brokerage services. All uses of CCAs by Janus Capital, Janus Singapore, and Perkins are subject to applicable law and their best execution obligations. Brokerage and research products and services furnished by brokers may be used in servicing any or all of the clients of Janus Capital, Janus Singapore, or Perkins and such research may not necessarily be used by Janus Capital, Janus Singapore, or Perkins in connection with the accounts which paid commissions to the broker providing such brokerage and research products and services. Similarly, research and brokerage services paid for with commissions generated by equity trades may be used for fixed-income clients that normally do not pay brokerage commissions or other clients whose

68  

commissions are generally not used to obtain such research and brokerage services. Janus Singapore and Perkins may make their own separate arrangements with and maintain internal allocation procedures for allocating transactions to brokers who provide research products and services to encourage them to provide services expected to be useful to Janus Singapore’s and Perkins’ clients, including Janus Asia Equity Fund and Perkins Global Value Fund.

Janus Capital, Janus Singapore, and Perkins may also use step-out transactions in order to receive research products and related services. In a step-out transaction, Janus Capital, Janus Singapore, or Perkins directs trades to a broker-dealer with the instruction that the broker-dealer execute the transaction, but “step-out” all or a portion of the transaction or commission in favor of another broker-dealer that provides such products and/or services. The second broker-dealer may clear and settle and receive commissions for the stepped-in portion. In a new issue designation, Janus Capital, Janus Singapore, or Perkins directs purchase orders to a broker-dealer that is a selling group member or underwriter of an equity or fixed-income new issue offering. Janus Capital, Janus Singapore, or Perkins directs that broker-dealer to designate a portion of the broker-dealer’s commission on the new issue purchase to a second broker-dealer(s) that provides such products and/or services. Given Janus Capital’s, Janus Singapore’s, and Perkins’ receipt of such products and services in connection with step-out transactions and new issue designations, Janus Capital, Janus Singapore, and Perkins have an incentive to continue to engage in such transactions; however, Janus Capital, Janus Singapore, and Perkins only intend to utilize step-out transactions and new issue designations when they believe that doing so would not hinder best execution efforts.

When the Funds purchase or sell a security in the over-the-counter market, the transaction takes place directly with a principal market-maker, without the use of a broker, except in those circumstances where, in the opinion of Janus Capital or the subadviser, better prices and executions will be achieved through the use of a broker.

The following tables list the total amount of brokerage commissions paid by each Fund for the fiscal years or periods noted.

Trustees and officers

The following are the Trustees and officers of the Trust, together with a brief description of their principal occupations during the last five years (principal occupations for certain Trustees may include periods over five years). As of the date of this SAI, none of the Trustees are “interested persons” of Janus Capital as that term is defined by the 1940 Act.

Each Trustee has served in that capacity since he or she was originally elected or appointed. The Trustees do not serve a specified term of office. Each Trustee will hold office until the termination of the Trust or his or her earlier death, resignation, retirement, incapacity, or removal. Pursuant to the Funds’ Governance Procedures and Guidelines, Trustees are required to retire no later than the end of the calendar year in which the Trustee turns 72. The Trustees review the Funds’ Governance Procedures and Guidelines from time to time and may make changes they deem appropriate. The Funds’ Nominating and Governance Committee will consider nominees for the position of Trustee recommended by shareholders. Shareholders may submit the name of a candidate for consideration by the Committee by submitting their recommendations to the Trust’s Secretary. Each Trustee is currently a Trustee of one other registered investment company advised by Janus Capital: Janus Aspen Series. As of the date of this SAI, collectively, the two registered investment companies consist of 56 series or funds.

The Trust’s officers are elected annually by the Trustees for a one-year term. Certain officers also serve as officers of Janus Aspen Series. Certain officers of the Funds may also be officers and/or directors of Janus Capital. Fund officers receive no compensation from the Funds, except for the Funds’ Chief Compliance Officer, as authorized by the Trustees.

As discussed below, the Board’s Nominating and Governance Committee is responsible for identifying and recommending candidates for nomination or election by the Board based on a variety of diverse criteria. In its most recent evaluation of the qualifications of each Trustee prior to the election of Trustees in 2010 and in connection with the assessment of candidates prior to the appointment of a new Trustee effective January 1, 2011, the Committee and the Board considered the totality of the information available to them, including the specific experience, qualifications, attributes or skills, as noted below, and concluded that each of the Trustees should serve as members of the Board of Trustees based on the Trust’s business structure. In reaching these conclusions, the Committee and the Board, in the exercise of their reasonable business judgment, evaluated each Trustee based on his or her specific experience, qualifications, attributes and/or skills on an individual basis and in combination with the other Trustees, none of which by itself was considered dispositive.

General Information Regarding the Board of Trustees and Leadership Structure

The Trust is governed by the Board of Trustees, which is responsible for and oversees the management and operations of the Trust and each of the Janus funds on behalf of fund shareholders. Each member of the Board is an Independent Trustee, including the Board’s Chairman. The Board’s responsibilities include, but are not limited to, oversight of the Janus funds’ officers and service providers, including Janus Capital, which is responsible for the Trust’s day-to-day operations. The Trustees approve all of the agreements entered into with the Janus funds’ service providers, including the investment management agreements with Janus Capital and any applicable subadviser. The Trustees are also responsible for determining or changing each Janus fund’s investment objective(s), policies, and available investment techniques, as well as for overseeing the fund’s Chief Compliance Officer. In carrying out these responsibilities, the Trustees are assisted by the Trust’s independent auditor (who reports directly to the Trust’s Audit Committee), independent counsel, an independent fee consultant, and other specialists as appropriate, all of whom are selected by the Trustees. The Trustees also meet regularly without representatives of Janus Capital or its affiliates present.

The Trustees discharge their responsibilities collectively as a Board, as well as through Board committees, each of which operates pursuant to a Board-approved charter that delineates the specific responsibilities of that committee. For example, the Board as a whole is responsible for oversight of the annual process by which the Board considers and approves each fund’s investment advisory agreement with Janus Capital, but specific matters related to oversight of the Janus funds’ independent auditors have been delegated by the Board to its Audit Committee, subject to approval of the Audit Committee’s recommendations by the Board. The members and responsibilities of each Board committee are summarized below. In addition to serving on certain committees, the Chairman of the Board (“Board Chairman”) is responsible for presiding at all meetings of the Board, and has other duties as may be assigned by the Trustees from time to time. The Board Chairman also serves as the Board’s liaison to Janus Capital with respect to all matters related to the Janus funds that are not otherwise delegated to the chair of a Board committee. The Board has determined that this leadership structure is appropriate based on (1) the number of Janus funds overseen and the various investment objectives of those funds; (2) the manner in which the Janus funds’ shares are marketed and distributed; and (3) the responsibilities entrusted to Janus Capital and its affiliates to oversee the Trust’s day-to-day operations, including the management of each Janus fund’s holdings and the distribution of fund shares. On an annual basis, the Board conducts a self-evaluation that considers, among other matters, whether the Board and its committees are functioning effectively and whether, given the size and composition of the Board and each of its committees, the Trustees are able to oversee effectively the number of Janus funds in the complex.

78  

Committees of the Board

The Board of Trustees has seven standing committees that each perform specialized functions: an Audit Committee, Brokerage Committee, Investment Oversight Committee, Legal and Regulatory Committee, Money Market Committee, Nominating and Governance Committee, and Pricing Committee.

Board Oversight of Risk Management

Janus Capital, as part of its responsibilities for the day-to-day operations of the Janus funds, is responsible for day-to-day risk management for the funds. The Board, as part of its overall oversight responsibilities for the Janus funds’ operations, oversees Janus Capital’s risk management efforts with respect to the funds. The Board, in the exercise of its reasonable business judgment, also separately considers potential risks that may impact the Janus funds. The Board discharges its oversight duties

  79

and considers potential risks in a number of different ways, including, but not limited to, receiving reports on a regular basis, either directly or through an appropriate committee, from Janus Capital and its officers. Reports received include those from, among others, Janus Capital’s (1) senior managers responsible for oversight of global risk; (2) senior managers responsible for oversight of fund construction and trading risk; (3) Chief Compliance Officer; and (4) Director of Internal Audit. At the time these reports are presented, the Board or the committee receiving the report will, as it deems necessary, invite the presenter to participate in an executive session to discuss matters outside the presence of any other officers or representatives of Janus Capital or its affiliates. The Board also receives reports from other entities and individuals unaffiliated with Janus Capital, including reports from the Janus funds’ other service providers and from independent consultants hired by the Board.

Various Board committees also will consider particular risk items as the committee addresses items and issues specific to the jurisdiction of that committee. For example, the Pricing Committee will consider valuation risk as part of its regular oversight responsibilities, and similarly, the Brokerage Committee will consider counterparty risk associated with Janus fund transactions. The Board also may be apprised of particular risk management matters in connection with its general oversight and approval of various Janus fund matters brought before the Board. The Board has appointed a Chief Compliance Officer for the Janus funds (“Fund CCO”) who (1) reports directly to the Board and (2) provides a comprehensive written report annually and presents quarterly at the Board’s regular meetings. The Fund CCO, who also serves as Janus Capital’s Chief Compliance Officer, discusses relevant risk issues that may impact the Janus funds and/or Janus Capital’s services to the funds, and routinely meets with the Board in private without representatives of Janus Capital or its affiliates present. The Fund CCO also provides the Board with updates on the application of the Janus funds’ compliance policies and procedures, including how these procedures are designed to mitigate risk and what, if any, changes have been made to enhance the procedures. The Fund CCO may also report to the Board on an ad hoc basis in the event that he identifies issues associated with the Janus funds’ compliance policies and procedures that could expose the funds to additional risk or adversely impact the ability of Janus Capital to provide services to the funds.

The Board believes that its leadership structure permits it to effectively discharge its oversight responsibilities with respect to the Janus funds’ risk management process.

Additional Information About Trustees

Under the Trust’s Governance Procedures and Guidelines, the Trustees are expected to invest in one or more (but not necessarily all) funds advised by Janus Capital for which they serve as Trustee, to the extent they are directly eligible to do so. These investments may include amounts held under a deferred compensation plan that are valued based on “shadow investments” in such funds. Such investments, including the amount and which funds, are dictated by each Trustee’s individual financial circumstances and investment goals. The table below gives the dollar range of shares of the Funds that the Trustees own and which are described in this SAI, as well as the aggregate dollar range of shares of all mutual funds advised by Janus Capital and overseen by the Trustees (collectively, the “Janus Funds”), owned by each Trustee as of December 31, 2011.

(1)  Ownership shown includes amounts held under a deferred compensation plan that are valued based on “shadow investments” in one or more funds.

The Trust pays each Independent Trustee an annual retainer plus a fee for each regular in-person meeting of the Trustees attended, a fee for in-person meetings of committees attended if convened on a date other than that of a regularly scheduled meeting, and a fee for telephone meetings of the Trustees and committees. In addition, committee chairs and the Chairman of the Board of Trustees receive an additional supplemental retainer. Each current Independent Trustee also receives fees from other Janus funds for serving as Trustee of those funds. Janus Capital pays persons who are directors, officers, or employees of Janus Capital or any affiliate thereof, or any Trustee considered an “interested” Trustee, for their services as Trustees or officers. The Trust and other funds managed by Janus Capital may pay all or a portion of the compensation and related expenses of the Funds’ Chief Compliance Officer and compliance staff, as authorized from time to time by the Trustees.

The following table shows the aggregate compensation paid to each Independent Trustee by the Funds described in this SAI and all Janus Funds for the periods indicated. None of the Trustees receives any pension or retirement benefits from the Funds or the Janus Funds. Effective January 1, 2006, the Trustees established a deferred compensation plan under which the Trustees may elect to defer receipt of all, or a portion, of the compensation they earn for their services to the Funds, in lieu of receiving current payments of such compensation. Any deferred amount is treated as though an equivalent dollar amount has been invested in shares of one or more funds advised by Janus Capital (“shadow investments”).

(6)  One of the accounts included in the total, consisting of $834,758,065 of the total assets in the category, has a performance-based advisory fee.

Material Conflicts

As shown in the table above, certain portfolio managers may manage other accounts with investment strategies similar to the Funds. Those other accounts may include other Janus funds, private-label mutual funds for which Janus Capital serves as subadviser, and separately managed accounts or other pooled investment vehicles, such as hedge funds, which may have materially higher fees than a Fund or may have a performance-based management fee. As such, fees earned by Janus Capital may vary among these accounts. In addition, the portfolio managers may personally invest in some but not all of these accounts, and certain of these accounts may have a greater impact on their compensation than others. Certain portfolio managers may also have roles as research analysts for one or more Janus funds and receive compensation with respect to the analyst role. These factors could create conflicts of interest because a portfolio manager may have incentives to favor certain accounts over others, resulting in the potential for other accounts outperforming a Fund. A conflict may also exist if a portfolio manager identifies a limited investment opportunity that may be appropriate for more than one account, but a Fund is not able to take full advantage of that opportunity due to the need to allocate that opportunity among multiple accounts. In addition, the portfolio manager may execute transactions for another account that may adversely impact the value of securities held by the Fund. However, Janus Capital believes that these conflicts may be mitigated to a certain extent by the fact that accounts with like investment strategies managed by a particular portfolio manager are generally managed in a similar fashion, subject to a variety of exceptions, for example, to account for particular investment restrictions or policies applicable only to certain accounts, certain portfolio holdings that may be transferred in-kind when an account is opened, differences in cash flows and account sizes, and similar factors. In addition, Janus Capital has adopted trade allocation procedures that govern allocation of securities among various Janus accounts. Trade allocation and personal trading are described in further detail under “Additional Information About Janus Capital and the Subadvisers.”

Janus Capital is the adviser to the Funds and the Janus “funds of funds,” which are funds that invest primarily in other Janus Capital mutual funds. Because Janus Capital is the adviser to the Janus “funds of funds” and the Funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus “fund of funds” among such Funds. In addition, the Janus “funds of funds” portfolio manager, who also serves as Senior Vice President and Chief Risk Officer of Janus Capital, has regular and continuous access to information regarding the holdings of the Funds, as well as knowledge of, and potential impact on, investment strategies and techniques of the Funds. Janus Capital believes these potential conflicts may be mitigated through its compliance monitoring, including that of asset allocations by the portfolio manager. In addition, Janus Capital has retained an independent consultant to provide research and consulting services with respect to asset allocation and investments for Janus Conservative Allocation Fund, Janus Moderate Allocation Fund, and Janus Growth Allocation Fund, which are “funds of funds” offered by Janus Capital.

Compensation Information

The following describes the structure and method of calculating a portfolio manager’s compensation as of September 30, 2011.

The portfolio managers and, if applicable, co-portfolio managers (“portfolio manager” or “portfolio managers”) are compensated for managing a Fund and any other funds, portfolios, or accounts for which they have exclusive or shared responsibilities (collectively, the “Managed Funds”) through two components: fixed compensation and variable compensation. Certain portfolio managers are eligible to receive additional discretionary compensation in recognition of their continued analyst responsibilities, and the Chief Investment Officers (“CIO”) of Janus Capital are eligible for additional variable compensation in recognition of their CIO roles, each as noted below. In addition, certain portfolio managers who have an

  83

ownership interest or profits interest in certain Janus adviser affiliated entities may receive compensation through those interests.

Fixed Compensation: Fixed compensation is paid in cash and is comprised of an annual base salary based on factors such as the complexity of managing funds and other accounts and scope of responsibility (including assets under management).

Variable Compensation: Variable compensation is paid in the form of cash and long-term incentive awards (consisting of a mixture of JCGI restricted stock and a cash-deferred award that is credited with income, gains, and losses based on the performance of Janus mutual fund investments selected by the portfolio manager). The overall investment team compensation pool is funded each year by an amount equal to a percentage of Janus Capital’s pre-incentive operating income.

Variable compensation is structured to pay a portfolio manager on a quarterly basis primarily on the Managed Funds’ performance, with additional discretionary compensation available from a discretionary variable compensation pool described below.

With respect to any individual portfolio manager’s quarterly variable compensation, the management fee revenue received by Janus Capital in connection with such portfolio manager’s Managed Funds determines the maximum compensation that the individual portfolio manager can receive on a quarterly basis, which is then adjusted downward depending on the portfolio manager’s investment performance on a one-, three-, and five-year rolling period basis with a predominant weighting on the Managed Funds’ performance in the three- and five-year periods. Actual performance is calculated based on the Managed Funds’ aggregate asset-weighted Lipper peer group performance ranking (or, as may be applicable, a combination of two or more Lipper peer groups).

A portfolio manager is also eligible to participate in a discretionary variable compensation pool. The aggregate compensation available under such pool is determined by management at its sole discretion from the overall investment team pool described above. Compensation from the discretionary investment team pool is then allocated among the eligible respective participants at the discretion of Janus Capital based upon, among other things: (i) thought leadership; (ii) mentoring of analysts; (iii) contributions to the sales process; (iv) teamwork and support of team culture; and (v) client relationships.

Newly hired portfolio managers may have guaranteed compensation levels during the first few years of their employment with Janus.

Analyst Variable Compensation: If a portfolio manager also has analyst responsibilities, then such portfolio manager is eligible to participate in a discretionary variable compensation pool. The aggregate compensation available under such pool is determined by management at its sole discretion from the overall investment team pool described above. The aggregate compensation is then allocated among the eligible respective participants at the discretion of Janus Capital based on factors which may include performance of investment recommendations, individual and team contributions, scope of coverage, and subjective criteria.

CIO Variable Compensation: The CIOs are entitled to additional compensation at management’s sole discretion in consideration of their role as CIO of Janus Capital that is generally based on firm-wide investment performance (excluding assets managed by subadvisers), Janus-managed net long-term flows (excluding assets managed by subadvisers and money market funds), investment team leadership factors, and overall corporate leadership factors.

Portfolio managers may elect to defer payment of a designated percentage of their fixed compensation and/or up to all of their variable compensation in accordance with JCGI’s Executive Income Deferral Program.

Additional Compensation Information

The following describes the structure and method of calculating compensation for James Goff, Director of Equity Research, as of September 30, 2011.

Mr. Goff is compensated for his role as Director of Equity Research and for managing a Fund and any other funds, portfolios, or accounts managed by Mr. Goff through two components: fixed compensation and variable compensation.

Fixed Compensation: Fixed compensation is paid in cash and is comprised of an annual base salary based on factors such as his scope of responsibility, tenure, his performance as the Director of Research, and for managing funds.

Variable Compensation: Variable compensation is paid in the form of cash and long-term incentive awards (consisting of a mixture of JCGI restricted stock and a cash-deferred award that is credited with income, gains, and losses based on the performance of Janus mutual fund investments selected by Mr. Goff). Mr. Goff’s variable compensation opportunity is based on four components: (i) firm-wide investment performance; (ii) Janus Capital long-term net flows (excluding assets managed

84  

by subadvisers and money market funds); (iii) certain strategic objectives, including investment team culture, analyst recruitment and development, continued enhancements to the research process, and contributions to sales and client efforts; and (iv) the research portfolios’ investment performance. Variable compensation from firm-wide investment performance and the research portfolios’ investment performance is calculated based upon a percentage of the revenue received from the applicable funds (excluding assets managed by subadvisers) and is adjusted to reflect the actual performance of such funds. Actual performance is calculated based on the applicable funds’ aggregate asset-weighted Lipper peer group performance (or, as may be applicable, a combination of two or more Lipper peer groups) ranking on a one- and three-year rolling period basis (with a predominant weighting on three-year performance for the research portfolios investment performance calculation).

Mr. Goff may elect to defer payment of a designated percentage of his fixed compensation and/or up to all of his variable compensation in accordance with JCGI’s Executive Income Deferral Program.

Each Fund’s Lipper peer group for compensation purposes is shown in the following table:

PERKINS INVESTMENT PERSONNEL

Other Accounts Managed

To the best knowledge of the Trust, the following table provides information relating to other accounts managed by the portfolio manager as of September 30, 2011. No accounts included in the totals listed below have a performance-based advisory fee.

Material Conflicts

As shown in the table above, Perkins Global Value Fund’s portfolio manager may manage other funds and accounts with investment strategies similar to the Fund. Fees earned by the adviser may vary among these accounts, the portfolio manager may personally invest in some but not all of these accounts, and certain of these accounts may have a greater impact on the portfolio manager’s compensation than others. These factors could create conflicts of interest because the portfolio manager may have incentives to favor certain accounts over others, resulting in the potential for other accounts outperforming the Fund. A conflict may also exist if the portfolio manager identifies a limited investment opportunity that may be appropriate for more than one account, but the Fund is not able to take full advantage of that opportunity due to the need to allocate that opportunity among multiple accounts. In addition, the portfolio manager may execute transactions for another account that may adversely impact the value of securities held by the Fund. However, Perkins believes that these conflicts may be mitigated to a certain extent by the fact that accounts with like investment strategies managed by the portfolio manager are generally managed in a similar fashion, subject to a variety of exceptions, for example, to account for particular investment restrictions or policies applicable only to certain accounts, certain portfolio holdings that may be transferred in-kind when an account is opened, differences in cash flows and account sizes, and similar factors. Information regarding Perkins’ trade allocation procedures is described under “Additional Information About Janus Capital and the Subadvisers.”

Compensation Information

The following describes the structure and method of calculating the portfolio manager’s compensation as of September 30, 2011.

The portfolio manager is compensated for managing the Fund and any other funds, portfolios, or accounts for which he has exclusive or shared responsibilities (collectively, the “Managed Funds”) through two components: fixed compensation and variable compensation. In addition, certain portfolio managers who have an ownership interest or profits interest in Perkins may receive compensation through those interests.

Fixed Compensation: Fixed compensation is paid in cash and is comprised of an annual base salary based on factors such as the complexity of managing funds and other accounts and scope of responsibility (including assets under management).

Variable Compensation: Variable compensation is paid in the form of cash and long-term incentive awards (potentially consisting of all or a mixture of JCGI restricted stock and/or a cash-deferred award that is credited with income, gains, and losses based on the performance of mutual fund investments selected by the portfolio manager). The overall Perkins’ compensation pool is funded each year based upon a percentage of the total eligible revenue received by Perkins, with a potential increase in funding based on Perkins’ aggregate revenue-weighted Lipper peer group performance ranking on a trailing three-year basis.

From the overall Perkins’ compensation pool described above, variable compensation is paid to a portfolio manager based primarily on the Managed Funds’ performance, with additional discretionary compensation opportunities. The size of the discretionary bonus pool fluctuates depending on both the revenue derived from firm-wide managed assets and the investment performance of such firm-wide managed assets. Compensation from the discretionary bonus pool is allocated among the eligible respective participants at the discretion of Perkins management based upon, among other things: (i) teamwork and support of team culture; (ii) mentoring of analysts; (iii) contributions to the sales process; (iv) client relationships; and (v) if applicable, CIO duties.

Shares of the trust

Although Janus Twenty Fund is closed, certain investors may continue to invest in the Fund and/or open new Fund accounts as described in the Fund’s Prospectuses. The “Shareholder’s Manual” or “Shareholder’s Guide” section of the Fund’s Prospectuses contains detailed information about the purchase of shares.

NET ASSET VALUE DETERMINATION

As stated in the Funds’ Prospectuses, the net asset value (“NAV”) of the Shares of each class of each Fund is determined once each day the New York Stock Exchange (the “NYSE”) is open, as of the close of its regular trading session (normally 4:00 p.m., New York time, Monday through Friday). The per share NAV for each class of each Fund is computed by dividing the total value of securities and other assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares for the class. In determining NAV, securities listed on an Exchange, the NASDAQ National Market, and foreign markets are generally valued at the closing prices on such markets. If such price is lacking for the trading period immediately preceding the time of determination, such securities are valued at their current bid price. Municipal securities held by the Funds are traded primarily in the over-the-counter markets. Valuations of such securities are furnished by one or more pricing services employed by the Funds and approved by the Trustees and are based upon a computerized matrix system or appraisals obtained by a pricing service, in each case in reliance upon information concerning market transactions and quotations from recognized municipal securities dealers. Other securities that are traded on the over-the-counter markets are generally valued at their closing bid prices. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect at the close of the NYSE. Each Fund will determine the market value of individual securities held by it by using prices provided by one or more professional pricing services which may provide market prices to other funds or, as needed, by obtaining market quotations from independent broker-dealers. Short-term securities maturing within 60 days or less are valued on an amortized cost basis. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities, and ratings.

Securities for which market quotations are not readily available or are deemed unreliable are valued at fair value determined in good faith under procedures established by and under the supervision of the Trustees (the “Valuation Procedures”). Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a nonsignificant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a nonvalued security and a restricted or nonpublic security. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE.

Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed well before the close of business on each business day in New York (i.e., a day on which the NYSE is open). In addition, European or Far Eastern securities trading generally or in a particular country or countries may not take place on all business days in New York. Furthermore, trading takes place in Japanese markets on certain Saturdays and in various foreign markets on days which are not business days in New York and on which a Fund’s NAV is not calculated. A Fund calculates its NAV per share, and therefore effects sales, redemptions, and repurchases of its shares, as of the close of the NYSE once each day on which the NYSE is open. Such calculation may not take place contemporaneously with the determination of the prices of the foreign portfolio securities used in such calculation. If an event that is expected to affect the value of a portfolio security occurs after the close of the principal exchange or market on which that security is traded, and before the close of the NYSE, then that security may be valued in good faith under the Valuation Procedures.

To the extent there are any errors in a Fund’s NAV calculation, Janus Capital may, at its discretion, reprocess individual shareholder transactions so that each shareholder’s account reflects the accurate corrected NAV.

PURCHASES

With the exception of Class D Shares and Class I Shares, Shares of the Funds can generally be purchased only through institutional channels such as financial intermediaries and retirement platforms. Class D Shares and Class I Shares may be purchased directly with the Funds in certain circumstances as provided in the Funds’ Prospectuses. Not all financial intermediaries offer all classes. Shares or classes of the Funds may be purchased without upfront sales charges by certain retirement plans and clients of investment advisers, but these clients will typically pay asset-based fees for their investment advisers’ advice, which are on top of the Funds’ expenses. Certain Shares or classes of the Funds may also be purchased without upfront sales charges or transactional charges by persons who invest through mutual fund “supermarket” programs of certain financial intermediaries that typically do not provide investment recommendations or the assistance of an investment professional. Under certain circumstances, the Funds may permit an in-kind purchase of Class A Shares, Class C Shares, Class I Shares, Class R Shares, Class S Shares, or Class T Shares at the discretion of Janus Capital.

Certain designated organizations are authorized to receive purchase orders on the Funds’ behalf and those organizations are authorized to designate their agents and affiliates as intermediaries to receive purchase orders. Purchase orders are deemed received by a Fund when authorized organizations, their agents, or affiliates receive the order provided that such designated organizations or their agents or affiliates transmit the order to the Fund within contractually specified periods. The Funds are not responsible for the failure of any designated organization or its agents or affiliates to carry out its obligations to its customers. In order to receive a day’s price, your order for any class of Shares must be received in good order by the close of the regular trading session of the NYSE as described above in “Net Asset Value Determination.” Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Your financial intermediary, plan documents, or the Funds’ Prospectuses will provide you with detailed information about investing in the Funds.

The Trust has established an Anti-Money Laundering Compliance Program (the “Program”) as required by the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”). In an effort to ensure compliance with this law, the Trust’s Program provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

Procedures to implement the Program include, but are not limited to, determining that financial intermediaries have established proper anti-money laundering procedures, reporting suspicious and/or fraudulent activity, checking shareholder names against designated government lists, including the Office of Foreign Asset Control (“OFAC”), and a review of all new account applications. The Trust does not intend to transact business with any person or entity whose identity cannot be adequately verified under the provisions of the USA PATRIOT Act.

Class A Shares

The price you pay for Class A Shares is the public offering price, which is the NAV next determined after a Fund or its agent receives in good order your order plus an initial sales charge, if applicable, based on the amount invested as set forth in the table. The Fund receives the NAV. The sales charge is allocated between your financial intermediary and Janus Distributors, the Trust’s distributor, as shown in the table, except where Janus Distributors, in its discretion, allocates up to the entire amount to your financial intermediary. Sales charges, as expressed as a percentage of offering price, a percentage of your net investment, and as a percentage of the sales charge reallowed to financial intermediaries, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the NAV of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding. Although you pay no initial sales charge on purchases of $1,000,000 or more, Janus Distributors may pay, from its own resources, a commission to your financial intermediary on such investments.

**	A contingent deferred sales charge of 1.00% may apply to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase.

As described in the Prospectus, there are several ways you can combine multiple purchases of Class A Shares of the Funds and other Janus funds that are offered with a sales charge to take advantage of lower sales charges.

Class C Shares, Class D Shares, Class I Shares, Class R Shares, Class S Shares, and Class T Shares of the Funds are purchased at the NAV per share as determined at the close of the regular trading session of the NYSE next occurring after a purchase order is received in good order by a Fund or its authorized agent.

Janus Distributors also receives amounts pursuant to Class A Share, Class C Share, Class R Share, and Class S Share 12b-1 plans and, from Class A Shares and Class C Shares, proceeds of contingent deferred sales charges paid by investors upon certain redemptions, as detailed in the “Distribution and Shareholder Servicing Plans” and “Redemptions” sections, respectively, of this SAI.

Commission on Class C Shares

Janus Distributors may compensate your financial intermediary at the time of sale at a commission rate of up to 1.00% of the NAV of the Class C Shares purchased. Service providers to qualified plans will not receive this amount if they receive 12b-1 fees from the time of initial investment of qualified plan assets in Class C Shares.

DISTRIBUTION AND SHAREHOLDER SERVICING PLANS

Class A Shares, Class R Shares, and Class S Shares

As described in the Prospectuses, Class A Shares, Class R Shares, and Class S Shares have each adopted distribution and shareholder servicing plans (the “Class A Plan,” “Class R Plan,” and “Class S Plan,” respectively) in accordance with Rule 12b-1 under the 1940 Act. The Plans are compensation type plans and permit the payment at an annual rate of up to 0.25% of the average daily net assets of Class A Shares and Class S Shares and at an annual rate of up to 0.50% of the average daily net assets of Class R Shares of a Fund for activities that are primarily intended to result in the sale and/or shareholder servicing of Class A Shares, Class R Shares, or Class S Shares of such Fund, including, but not limited to, printing and delivering prospectuses, statements of additional information, shareholder reports, proxy statements, and marketing materials related to Class A Shares, Class R Shares, and Class S Shares to prospective and existing investors; providing educational materials regarding Class A Shares, Class R Shares, and Class S Shares; providing facilities to answer questions from prospective and existing investors about the Funds; receiving and answering correspondence; complying with federal and state securities laws pertaining to the sale of Class A Shares, Class R Shares, and Class S Shares; assisting investors in completing application forms and selecting dividend and other account options; and any other activities for which “service fees” may be paid under Rule 2830 of the Financial Industry Regulatory Authority, Inc. (“FINRA”) Conduct Rules. Payments under the Plans are not tied exclusively to actual distribution and shareholder service expenses, and the payments may exceed distribution and shareholder service expenses actually incurred. Payments are made to Janus Distributors, the Funds’ distributor, who may make ongoing payments to financial intermediaries based on the value of Fund shares held by such intermediaries’ customers. On December 5, 2008, the Trustees unanimously approved a distribution plan with respect to each of the Class A Shares, Class R Shares, and Class S Shares, which became effective on July 6, 2009.

Class C Shares

As described in the Prospectus, Class C Shares have adopted a distribution and shareholder servicing plan (the “Class��C Plan”) in accordance with Rule 12b-1 under the 1940 Act. The Class C Plan is a compensation type plan and permits the payment at an annual rate of up to 0.75% of the average daily net assets of Class C Shares of a Fund for activities which are primarily intended to result in the sale of Class C Shares of such Fund. In addition, the Plan permits the payment of up to 0.25% of the average daily net assets of Class C Shares of a Fund for shareholder servicing activities including, but not limited to, providing facilities to answer questions from existing investors about the Funds; receiving and answering correspondence; assisting investors in changing dividend and other account options and any other activities for which “service fees” may be paid under Rule 2830 of the FINRA Conduct Rules. Payments under the Class C Plan are not tied exclusively to actual distribution and shareholder service expenses, and the payments may exceed distribution and shareholder service expenses actually incurred. On December 5, 2008, the Trustees unanimously approved the Class C Plan, which became effective on July 6, 2009.

The Plans and any Rule 12b-1 related agreement that is entered into by the Funds or Janus Distributors in connection with the Plans will continue in effect for a period of more than one year only so long as continuance is specifically approved at least annually by a vote of a majority of the Trustees, and of a majority of the Trustees who are not interested persons (as defined in the 1940 Act) of the Trust and who have no direct or indirect financial interest in the operation of the Plans or any related agreements (“12b-1 Trustees”). All material amendments to any Plan must be approved by a majority vote of the Trustees, including a majority of the 12b-1 Trustees, at a meeting called for that purpose. In addition, any Plan may be terminated as to a Fund at any time, without penalty, by vote of a majority of the outstanding Shares of that Class of that Fund or by vote of a majority of the 12b-1 Trustees.

Janus Distributors is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although Janus Distributors may, pursuant to a written agreement between Janus Distributors and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.

For the fiscal year ended September 30, 2011, the total amounts paid by the Class A Shares, Class C Shares, Class R Shares, and Class S Shares of the Funds to Janus Distributors (substantially all of which Janus Distributors paid out as compensation to broker-dealers and other service providers) under each Class’ respective Plan are summarized below.

REDEMPTIONS

Redemptions, like purchases, may generally be effected only through institutional channels such as financial intermediaries and retirement platforms. Class D Shares and, in certain circumstances, Class I Shares may be redeemed directly with the Funds. Certain designated organizations are authorized to receive redemption orders on the Funds’ behalf and those organizations are authorized to designate their agents and affiliates as intermediaries to receive redemption orders. Redemption orders are deemed received by a Fund when authorized organizations, their agents, or affiliates receive the order. The Funds are not responsible for the failure of any designated organization or its agents or affiliates to carry out its obligations to its customers.

Certain accounts or Janus affiliates may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these accounts of their holdings in a Fund may impact the Fund’s liquidity and NAV. These redemptions may also force a Fund to sell securities, which may negatively impact the Fund’s brokerage costs.

Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a Fund, by delivery of securities selected from its assets at its discretion. However, each Fund is governed by Rule 18f-1 under the 1940 Act, which requires each Fund to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. If shares are redeemed in-kind, the redeeming shareholder may incur brokerage costs in converting the assets to cash, whereas such costs are borne by the Fund for cash redemptions. The method of valuing securities used to make redemptions in-kind will be the same as the method of valuing portfolio securities described under “Shares of the Trust – Net Asset Value Determination” and such valuation will be made as of the same time the redemption price is determined.

The Funds reserve the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.

Class A Shares

A contingent deferred sales charge (“CDSC”) of 1.00% will be deducted with respect to Class A Shares purchased without a sales load and redeemed within 12 months of purchase, unless waived, as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class A Shares redeemed.

Class C Shares

A CDSC of 1.00% will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless waived, as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class C Shares redeemed.

A redemption fee of 2.00% will be deducted from a shareholder’s redemption proceeds with respect to Class D Shares, Class I Shares, Class R Shares (as applicable), Class S Shares, and Class T Shares of Janus Global Market Neutral Fund, Janus Global Real Estate Fund, Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund, Janus Worldwide Fund, and Perkins Global Value Fund redeemed within 90 days of purchase, unless waived, as discussed in the Prospectuses. Effective April 2, 2012, Janus will no longer assess a redemption fee regardless of how long such Shares have been held.

Processing or Service Fees

Broker-dealers may charge their customers a processing or service fee in connection with the purchase or redemption of Fund shares. Each individual dealer determines and should disclose to its customers the amount and applicability of such a fee. Processing or service fees typically are fixed, nominal dollar amounts and are in addition to the sales and other charges described in the Prospectuses and this SAI. Consult your broker-dealer for specific information about any processing or service fees you may be charged.

Income dividends, capital gains distributions, and tax status

The following is intended to be a general summary of certain U.S. federal income tax consequences of investing in the Funds. It is not intended to be a complete discussion of all such federal income tax consequences, nor does it purport to deal with all categories of investors. This discussion reflects applicable tax laws of the United States as of the date of this SAI. However, tax laws may change or be subject to new interpretation by the courts or the IRS, possibly with retroactive effect. Investors are therefore advised to consult with their own tax advisers before making an investment in the Funds.

It is a policy of the Funds’ Shares to make distributions of substantially all of their respective investment income and any net realized capital gains. Any capital gains realized during each fiscal year, as defined by the Internal Revenue Code, are normally declared and payable to shareholders in December but, if necessary, may be distributed at other times as well. With the exception of Janus Balanced Fund and Janus Growth and Income Fund, each Fund declares and makes annual distributions of income (if any). Janus Balanced Fund and Janus Growth and Income Fund declare and make quarterly distributions of income.

The Funds intend to qualify as regulated investment companies by satisfying certain requirements prescribed by Subchapter M of the Internal Revenue Code. If a Fund failed to qualify as a regulated investment company in any taxable year, the Fund may be subject to federal income tax on its taxable income at corporate rates. In addition, all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, would generally be taxable to shareholders as ordinary income but may, at least in part, qualify for the dividends received deduction applicable to corporations or the reduced rate of taxation applicable to noncorporate holders for “qualified dividend income.” In addition, the Funds could be required to recognize unrealized gains, pay taxes and interest, and make distributions before requalifying as regulated investment companies that are accorded special tax treatment.

All income dividends and capital gains distributions, if any, on a Fund’s Shares are reinvested automatically in additional shares of the same class of Shares of that Fund at the NAV determined on the first business day following the record date.

The Funds may purchase securities of certain foreign corporations considered to be passive foreign investment companies by the Internal Revenue Code. In order to avoid taxes and interest that must be paid by the Funds, the Funds may make various elections permitted by the tax laws. However, these elections could require that the Funds recognize taxable income, which in turn must be distributed even though the Funds may not have received any income upon such an event.

Some foreign securities purchased by the Funds may be subject to foreign taxes which could reduce the yield on such securities. If the amount of foreign taxes is significant in a particular year, the Funds that qualify under Section 853 of the Internal Revenue Code may elect to pass through such taxes to shareholders, who will each decide whether to deduct such taxes or claim a foreign tax credit. If such election is not made by a Fund, any foreign taxes paid or accrued will represent an expense to the Fund, which will reduce its investment company taxable income.

A Fund’s investments in REIT equity securities, if any, may require the Fund to accrue and distribute income not yet received. In order to generate sufficient cash to make the requisite distributions, the Fund may be required to sell securities at a time when fundamental investment considerations would not favor such sales. The Fund’s investments in REIT equity securities may result in the receipt of cash in excess of the REIT’s earnings. If a Fund distributes such amounts, such distribution could constitute a return of capital to shareholders for federal income tax purposes.

Some REITs are permitted to hold “residual interests” in real estate mortgage investment conduits (“REMICs”). Pursuant to the IRS rules, a portion of a Fund’s income from a REIT or “excess inclusion income” that is attributable to the REIT may be subject to federal income tax. Excess inclusion income will normally be allocated to shareholders in proportion to the dividends received by such shareholders. There may be instances in which the Fund may be unaware of a REIT’s excess inclusion income.

As a result of excess inclusion income, the Fund may be subject to additional tax depending on the type of record holder of Fund shares, such as certain federal, state, and foreign governmental entities, tax exempt organizations, and certain rural electrical and telephone cooperatives (“disqualified organizations”). This may impact the Fund’s performance.

Please consult a tax adviser regarding tax consequences of Fund distributions and to determine whether you will need to file a tax return.

Please note that shareholders of Janus Global Real Estate Fund may receive account tax information from the Fund at the end of February of the following year, which is one month later than when most such forms are sent.

100  

Janus Global Real Estate Fund’s investments in REITs may require the Fund to pass through certain “excess inclusion income” as “unrelated business taxable income” (“UBTI”). Tax-exempt investors sensitive to UBTI are strongly encouraged to consult their tax advisers prior to investment in the Fund regarding recent IRS pronouncements about the treatment of such income for certain tax-exempt investors.

Certain fund transactions involving short sales, futures, options, swap agreements, hedged investments, and other similar transactions, if any, may be subject to special provisions of the Internal Revenue Code that, among other things, may affect the character, amount, and timing of distributions to shareholders. The Funds will monitor their transactions and may make certain tax elections where applicable in order to mitigate the effect of these provisions, if possible. Certain transactions or strategies utilized by a Fund may generate nonqualified income that can impact an investor’s taxes.

Principal shareholders

As of December 31, 2011, the officers and Trustees as a group owned approximately 11.2% of Class A Shares of Janus Global Market Neutral Fund, 1.4% of Class I Shares of Janus Global Market Neutral Fund, 11.7% of Class I Shares of Janus Emerging Markets Fund, 10.1% of Class I Shares of Janus Global Life Sciences Fund, 5.0% of Class I Shares of Janus Global Research Fund, 11.9% of Class T Shares of Janus International Equity Fund, 6.0% of Class T Shares of Janus Forty Fund, 8.9% of Class A Shares of Janus Growth and Income Fund, 1.6% of Class I Shares of Janus Growth and Income Fund, 8.3% of Class I Shares of Perkins Global Value Fund, 9.2% of Class T Shares of Perkins Global Value Fund, and less than 1% of the outstanding Shares of any class of each of the other Funds in this SAI. As of December 31, 2011, the percentage ownership of any person or entity owning 5% or more of the outstanding Shares of any class of the Funds is listed below. In addition, the percentage ownership of any person or entity owning 25% or more of the outstanding Shares of any class of the Funds is listed below. Any person who owns, directly or through one or more controlled companies, more than 25% of the voting securities of a company is presumed to “control” such company. Accordingly, to the extent that a person is identified as the beneficial owner of more than 25% of a Fund, or is identified as the record owner of more than 25% of a Fund and has voting and/or investment powers, that person may be presumed to control such Fund. A controlling person’s vote could have a more significant effect on matters presented to shareholders for approval than the vote of other Fund shareholders.

To the best knowledge of the Trust, as of December 31, 2011, no other person or entity owned beneficially more than 5% of the outstanding Shares of any class of the Funds, except as shown. Additionally, to the best knowledge of the Trust, except for JCM’s or JCGI’s ownership in a Fund, no other person or entity beneficially owned 25% or more of the outstanding Shares of any class of the Funds, except as shown. In certain circumstances, JCM’s or JCGI’s ownership may not represent beneficial ownership. To the best knowledge of the Trust, other entities shown as owning more than 25% of the outstanding Shares of a class of a Fund are not the beneficial owners of such Shares, unless otherwise indicated.

On July 6, 2009, the funds of the Janus Adviser Series trust reorganized into the Trust. As a result, certain Funds described in this SAI assumed the assets and liabilities of the corresponding Janus Adviser Series funds. For this reason, certain historical information contained in this SAI for periods prior to July 6, 2009 is that of the predecessor funds. The Funds involved in the reorganizations had a fiscal year end of either October 31 or July 31. Each Fund described in this SAI has a fiscal year end of September 30.

Janus Capital reserves the right to the name “Janus.” In the event that Janus Capital does not continue to provide investment advice to the Funds, the Funds must cease to use the name “Janus” as soon as reasonably practicable.

Under Massachusetts law, shareholders of the Funds could, under certain circumstances, be held liable for the obligations of their Fund. However, the Amended and Restated Agreement and Declaration of Trust disclaims shareholder liability for acts or obligations of the Funds and requires that notice of this disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Funds or the Trustees. The Amended and Restated Agreement and Declaration of Trust also provides for indemnification from the assets of the Funds for all losses and expenses of any Fund shareholder held liable for the obligations of their Fund. Thus, the risk of a shareholder incurring a financial loss on account of their liability as a shareholder of one of the Funds is limited to circumstances in which their Fund would be unable to meet its obligations. The possibility that these circumstances would occur is remote. The Trustees intend to conduct the operations of the Funds to avoid, to the extent possible, liability of shareholders for liabilities of their Fund.

It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust and in accordance with any applicable regulations and laws, such as the 1940 Act, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent. Any such consolidation, merger, or reorganization may be authorized at any time by a vote of a majority of the Trustees then in office.

SHARES OF THE TRUST

The Trust is authorized to issue an unlimited number of shares of beneficial interest with a par value of one cent per share for each series of the Trust. Shares of each series of the Trust are fully paid and nonassessable when issued. Shares of a Fund participate equally in dividends and other distributions by the Shares of the same class of that Fund, and in residual assets of that class of that Fund in the event of liquidation. Shares of each Fund have no preemptive, conversion, or subscription rights. Shares of each Fund may be transferred by endorsement or stock power as is customary, but a Fund is not bound to recognize any transfer until it is recorded on its books.

SHAREHOLDER MEETINGS

The Trust does not intend to hold annual or regular shareholder meetings unless otherwise required by the Amended and Restated Agreement and Declaration of Trust or the 1940 Act. Special meetings may be called for a specific Fund or for the Trust as a whole for purposes such as changing fundamental policies, electing or removing Trustees, making any changes to the Amended and Restated Agreement and Declaration of Trust that would materially adversely affect shareholders’ rights, determining whether to bring certain derivative actions, or for any other purpose requiring a shareholder vote under applicable law or the Trust’s governing documents, or as the Trustees consider necessary or desirable.

Under the Amended and Restated Agreement and Declaration of Trust, special meetings of shareholders of the Trust or of any Fund shall be called subject to certain conditions, upon written request of shareholders owning shares representing at least 10% of the shares then outstanding. The Funds will assist these shareholders in communicating with other shareholders in connection with such a meeting similar to that referred to in Section 16(c) of the 1940 Act.

VOTING RIGHTS

The Trustees of the Trust (excluding Mr. Cvengros, a new Trustee) were elected at a Special Meeting of Shareholders on June 10, 2010. Under the Amended and Restated Agreement and Declaration of Trust, each Trustee will continue in office until the termination of the Trust or his or her earlier death, retirement, resignation, incapacity, or removal. Vacancies will be filled by appointment by a majority of the remaining Trustees, subject to the 1940 Act.

As a shareholder, you are entitled to one vote for each whole dollar and a proportionate fractional vote for each fractional dollar of NAV of the Fund that you own. Generally, all funds and classes vote together as a single group, except where a separate vote of one or more funds or classes is required by law or where the interests of one or more funds or classes are affected differently from other funds or classes. Shares of all series of the Trust have noncumulative voting rights, which

  135

means that the holders of more than 50% of the value of shares of all series of the Trust voting for the election of Trustees can elect 100% of the Trustees if they choose to do so. In such event, the holders of the remaining value of shares will not be able to elect any Trustees.

MASTER/FEEDER OPTION

The Trust may in the future seek to achieve a fund’s objective by investing all of that fund’s assets in another investment company having the same investment objective and substantially the same investment policies and restrictions as those applicable to that fund. Unless otherwise required by law, this policy may be implemented by the Trustees without shareholder approval.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

REGISTRATION STATEMENT

Appendix A

EXPLANATION OF RATING CATEGORIES

The following is a description of credit ratings issued by three of the major credit rating agencies. Credit ratings evaluate only the safety of principal and interest payments, not the market value risk of lower quality securities. Credit rating agencies may fail to change credit ratings to reflect subsequent events on a timely basis. Although Janus Capital and Perkins consider security ratings when making investment decisions, they also perform their own investment analyses and do not rely solely on the ratings assigned by credit agencies.

STANDARD & POOR’S RATINGS SERVICE

Bond Rating	Explanation
Investment Grade
AAA	Highest rating; extremely strong capacity to pay principal and interest.
AA	High quality; very strong capacity to pay principal and interest.
A	Strong capacity to pay principal and interest; somewhat more susceptible to the adverse effects of changing circumstances and economic conditions.
BBB	Adequate capacity to pay principal and interest; normally exhibit adequate protection parameters, but adverse economic conditions or changing circumstances more likely to lead to a weakened capacity to pay principal and interest than for higher rated bonds.
Non-Investment Grade
BB	Less vulnerable to nonpayment than other speculative issues; major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	More vulnerable to nonpayment than obligations rated “BB,” but capacity to meet its financial commitment on the obligation; adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	Currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.
CC	Currently highly vulnerable to nonpayment.
C	Currently highly vulnerable to nonpayment; a bankruptcy petition may have been filed or similar action taken, but payments on the obligation are being continued.
D	In default.

138  

FITCH, INC.

Long-Term Bond Rating	Explanation
Investment Grade
AAA	Highest credit quality. Denotes the lowest expectation of credit risk. Exceptionally strong capacity for payment of financial commitments.
AA	Very high credit quality. Denotes expectations of very low credit risk. Very strong capacity for payment of financial commitments.
A	High credit quality. Denotes expectations of low credit risk. Strong capacity for payment of financial commitments. May be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.
BBB	Good credit quality. Currently expectations of low credit risk. Capacity for payment of financial commitments is considered adequate, but adverse changes in circumstances and economic conditions are more likely to impair this capacity than is the case for higher ratings.
Non-Investment Grade
BB	Speculative. Indicates possibility of credit risk developing, particularly as the result of adverse economic change over time. Business or financial alternatives may be available to allow financial commitments to be met.
B	Highly speculative. May indicate distressed or defaulted obligations with potential for extremely high recoveries.
CCC	May indicate distressed or defaulted obligations with potential for superior to average levels of recovery.
CC	May indicate distressed or defaulted obligations with potential for average or below-average levels of recovery.
C	May indicate distressed or defaulted obligations with potential for below-average to poor recoveries.
D	In default.

FITCH, INC.

Short-Term Bond Rating	Explanation
F-1+	Exceptionally strong credit quality. Issues assigned this rating are regarded as having the strongest degree of assurance for timely payment.
F-1	Very strong credit quality. Issues assigned this rating reflect an assurance for timely payment only slightly less in degree than issues rated F-1+.
F-2	Good credit quality. Issues assigned this rating have a satisfactory degree of assurance for timely payments, but the margin of safety is not as great as the F-1+ and F-1 ratings.

  139

MOODY’S INVESTORS SERVICE, INC.

Bond Rating	Explanation
Investment Grade
Aaa	Highest quality, smallest degree of investment risk.
Aa	High quality; together with Aaa bonds, they compose the high-grade bond group.
A	Upper to medium-grade obligations; many favorable investment attributes.
Baa	Medium-grade obligations; neither highly protected nor poorly secured. Interest and principal appear adequate for the present but certain protective elements may be lacking or may be unreliable over any great length of time.
Non-Investment Grade
Ba	More uncertain, with speculative elements. Protection of interest and principal payments not well safeguarded during good and bad times.
B	Lack characteristics of desirable investment; potentially low assurance of timely interest and principal payments or maintenance of other contract terms over time.
Caa	Poor standing, may be in default; elements of danger with respect to principal or interest payments.
Ca	Speculative in a high degree; could be in default or have other marked shortcomings.
C	Lowest rated; extremely poor prospects of ever attaining investment standing.

Unrated securities will be treated as non-investment grade securities unless the portfolio managers and/or investment personnel determine that such securities are the equivalent of investment grade securities. When calculating the quality assigned to securities that receive different ratings from two or more agencies (“split-rated securities”), the security will receive: (i) the middle rating from the three reporting agencies if three agencies provide a rating for the security or (ii) the lowest rating if only two agencies provide a rating for the security.

SUMMARY

Sluggish economic growth continued over the past year, spurring additional stimulus from the world’s largest central banks. We believe these actions were necessary and are bullish for risk assets, including equities and corporate credit, in the short term. However, fundamental problems remain in Europe, the U.S. is moving toward the “fiscal cliff” and China’s growth is slowing. These issues likely will keep market volatility high for the foreseeable future.

EQUITIES: ROOM TO RUN

Accommodative actions taken by the European Central Bank and the U.S. Federal Reserve (Fed) over the past 12 months have helped lift equity markets, but we’ve seen this before. When pressure builds in the form of negative economic data, central banks release the pressure valve with a new wave of stimulus. Equity markets respond favorably for a time. In reality, sluggish economic growth and market volatility will persist until politicians in Europe and the U.S. present real solutions to their economic difficulties. The good news for investors is that even in this slow-growth environment, equity markets still have room to move higher, in our opinion.

Current equity valuations are in line with historical norms and do not stand out as irrationally cheap, or overly expensive. Dividend yields still compare very favorably to long-term Treasury yields, while providing the opportunity for long-term capital appreciation. With low rates expected until 2015, there is no prospect for yield anywhere else so dividend-paying stocks could move yet higher. Meanwhile, stocks with even a hint of macroeconomic sensitivity have been overly punished. When there is more certainty that macroeconomic conditions are improving, we believe these stocks are due for a significant bounce.

In a best-case scenario, politicians will resolve the impending “fiscal cliff” (when federal government spending cuts begin in January 2013, as payroll tax breaks, long-term unemployment benefits and Bush-era income tax rates are scheduled to end) and lay out a clear path for getting budgetary issues under control. This clarity would free up capital for productive investments, spur hiring and create an explosion of economic growth that could set in motion a historic run for equity markets. This is the best case for stock growth, but less likely. Instead, politicians are likely to push forth a patchwork extension of current tax breaks and spending measures, putting off a bigger budget debate and prolonging sluggish growth. Even in this less rosy scenario equity markets could still rise, driven by dynamic businesses that find ways to grow despite government. Finding companies with the right business drivers to grow in a muddling economy is a challenge we believe favors fundamental, research-driven stock picking.

FIXED INCOME: DON’T FIGHT THE FED

Fed Chairman Ben Bernanke has made it clear that the Fed intends to overshoot, keeping monetary policy accommodative even as the U.S. economy strengthens. There remain risks on the horizon, including the fiscal cliff, China’s economic slowdown and ongoing European debt problems. The Fed also has indicated that it wants to keep interest rates low to encourage investors to move further out on the risk spectrum, beyond Treasury securities and into riskier assets such as equities and corporate credit.

We believe that fixed income risk assets – i.e. credit and MBS – will benefit in the near term from anchored short-term interest rates and the liquidity provided by additional quantitative easing. However, we are keeping an eye on the potential for rising interest rates. While the immediacy of the risk is difficult to pinpoint at present, much depends on events that unfold over the next few months. Current low yields on corporate credit, in both high yield and investment grade markets, also have us leaning toward more defensive positioning.

OUTLOOK: FACING HEADWINDS

We view recent central bank actions as moves in the right direction, and absolutely required in light of the fragility of the global economy. However, global growth is the key factor. Although valuations are being driven higher by the liquidity being poured into the market, ultimately fundamental growth is needed. Europe has taken some steps toward solving its problems, and attention now shifts to the United States. We believe that if Washington can

get its act together and provide clarity on fiscal and tax policy, the relief would free up capital for productive investments, spur hiring by companies and lead to strong economic growth.

Sincerely,

Useful Information About Your Fund Report (unaudited)

Market Perspectives and Management Commentaries

The Management Commentaries in this report include valuable insight from each of the Fund’s managers as well as statistical information to help you understand how your Fund’s performance and characteristics stack up against those of comparable indices.

If a Fund invests in foreign securities, this report may include information about country exposure. Country exposure is based primarily on the country of domicile. However, the Funds’ managers may allocate a company to a country based on other factors such as location of the company’s principal office, the location of the principal trading market for the company’s securities, or the country where a majority of the company’s revenues are derived.

Please keep in mind that the opinions expressed by the Chief Investment Officer(s) (“CIO”) in the Market Perspective and by the Funds’ managers in the Management Commentaries are just that: opinions. They are a reflection of the CIOs’ and managers’ best judgment at the time this report was compiled, which was September 30, 2012. As the investing environment changes, so could their opinions. These views are unique to each CIO and manager and aren’t necessarily shared by fellow employees or by Janus in general.

Fund Expenses

We believe it’s important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

The following is important information regarding each Fund’s Expense Example, which appears in each Fund’s Management Commentary within this Annual Report. Please refer to this information when reviewing the Expense Example for each Fund.

Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments (applicable to Class A Shares only); and (2) ongoing costs, including management fees; distribution and shareholder servicing (12b-1) fees (applicable to Class A Shares, Class C Shares, Class R Shares and Class S Shares only); administrative services fees payable pursuant to the Transfer Agency Agreement; and other Fund expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based upon an investment of $1,000 invested at the beginning of the period and held for the six-month period from April 1, 2012 to September 30, 2012.

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

The second line of the table in each example provides information about hypothetical account values and hypothetical expenses based upon each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Additionally, for an analysis of the fees associated with an investment in each share class, please visit www.finra.org/fundanalyzer.

Janus Capital Management LLC (“Janus Capital”) has contractually agreed to waive certain Funds’ total annual fund operating expenses, excluding any performance adjustments to management fees, if applicable, class-specific distribution and shareholder servicing (12b-1) fees (applicable to Class A Shares, Class C Shares, Class R Shares and Class S Shares only), administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees for Class A Shares, Class C Shares and Class I Shares), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, to certain limits until at least February 1, 2013. Expenses in the examples reflect application of these waivers. Had the waivers not been in effect, your expenses would have been higher. More information

Janus Global & International Funds | 3

(Continued) (unaudited)

regarding the waivers is available in the Funds’ prospectuses.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs. These fees are fully described in the Funds’ prospectuses. Therefore, the second line of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Janus Asia Equity Fund (unaudited)

Fund Snapshot
We believe Asian economies and related equity markets are poised for secular growth. Given the world nature of these markets, equity prices may not at all times fully reflect business fundamentals. As such, fundamental research is the foundation of our Asia investment strategy.

Hiroshi Yoh
portfolio manager

Performance

For the 12-month period ended September 30, 2012, Janus Asia Equity Fund’s Class I Shares returned 24.90%, while the Fund’s benchmark, the MSCI All Country Asia ex-Japan Index, returned 19.58%.

Market Overview

Global equities moved significantly higher on policy announcements by the European Central Bank to address Europe’s sovereign debt crisis and the U.S. Federal Reserve to reverse slowing job growth in the U.S. Asia’s market gains came despite flattening economic growth in the region and Chinese political uncertainty prior to a leadership change later this fall. Adding to market volatility later in the period was a territorial dispute between China and Japan over five uninhabited islands, which led to protests against Japanese owned factories and stores in China. India’s market, which had lagged other markets, rebounded late in the period in part as the result of apparent progress in government attempts at reforming the country’s power sector.

Performance Overview

The Fund outperformed due largely to the strong relative performance of our holdings across sectors. On a country basis, our holdings in China and Taiwan were key contributors followed by our holdings in India.

Individually, Samsung Electronics Co., the Fund’s largest holding, was the most significant contributor. The company continued to expand its market share in smart phones globally and benefited from several product launches. While we recognize the company’s U.S. patent dispute with Apple represents a risk, we do not believe it will lead to a ban of Samsung products in the U.S. and that it will remain a global leader in smart phones. We consider Samsung to be the largest and most competitive electronics company in the world.

Great Wall Motor Co. was also a key contributor. The stock rose significantly after it reported strong year-over-year sales that outpaced peers. Through its exposure to faster growing regions, focus on SUVs and higher product quality, this Chinese automaker should grow faster than the market, in our view.

In Hong Kong, Sitoy Group Holdings, one of the largest producers of bags for luxury apparel makers such as Coach, Michael Kors and Prada (a 5% owner in the company), benefited from strong earnings. Sitoy enjoys a key competitive position given a structural shift in luxury production outsourcing to China due to capacity constraints in traditional markets such as France and Italy. We also view Sitoy as a cheaper way to gain exposure to growing demand for luxury products.

Relative detractors included our holdings in Malaysia and Mongolia. Individually, EVA Precision Industrial Holdings weighed the most on performance. Start-up costs for a new business segment have delayed a recovery in the company’s earnings. We decided to exit our position in the Chinese manufacturer of metal stamping and plastic injection molds.

China Lilang, one of China’s largest makers of men’s clothes and accessories, suffered inordinately during the period due to its smaller market capitalization and its stock market grouping with sportswear companies that lagged. The company’s fundamentals remain unchanged with strong revenue growth and margins. We like that the company’s wholesale business model leaves inventory risk, a concern of investors, with franchisees, and we feel that its margins are sustainable. Lilang’s target market of middle-level managers is also attractive for growth prospects as is the highly fragmented nature of the overall market that may allow for market share gains. We felt the stock’s price discounted most of the worries and could rebound.

Genting Singapore also weighed on performance. The casino operator declined in response to strict rules instituted by Singapore’s government intended to curb gambling for the less affluent. We sold our position.

Derivatives

During the period, we used swaps to access markets in which we were not trading locally either due to our risk policies or an inability to trade locally. In aggregate, these positions contributed to relative performance. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Outlook

Market expectations for 2013 earnings are coming down to reflect slowing economic growth, but we think corporate earnings will be better since the capital spending cycle for the region has peaked. If company revenues grow as they have been (and we think they will), we believe profitability will increase due to lower capital expenditures. This is particularly true in sectors where there has been oversupply, such as steel and cement, and even in the consumer sector, where we’re seeing a slowdown in store openings. Investors have grown very cautious and reduced expectations on economic growth due to slower-than-expected export growth, but in Asia domestic demand is still growing. We expect 7-8% GDP growth for China next year.

Major risks include the U.S. “fiscal cliff” (a legislatively mandated deadline on a series of tax and spending policies), which if it occurs could result in a short-term slowdown in U.S. growth. The ongoing European sovereign debt crisis remains worrisome as well, although fears have dampened somewhat as a result of the European Central Bank’s actions. The China-Japan territorial dispute is another concern, since this involves the second and third largest economies in the world.

In terms of positioning, we remain significantly overweight in consumer discretionary, which is one area where we see sustainable high growth potential. Our holdings within the sector, however, are quite varied and in areas where we believe supply is not saturated. In materials, we moved from an underweight to an overweight by adding several iron ore and coal companies. Price declines in both iron ore and coal, particularly in July and August, made it unprofitable for high cost producers, which we believe will reduce excess supply and allow prices in both commodities to rebound.

Thank you for your investment in Janus Asia Equity Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), real estate investment trusts (“REITs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in REITs which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Janus Asia Equity Fund held approximately 13.3%, 20.7% and 11.7% of its investments in Chinese, South Korean and Taiwanese securities, respectively, as of September 30, 2012, and the Fund may have experienced significant gains or losses due, in part, to its investments in China, South Korea and Taiwan. While holdings are subject to change without notice, the Fund’s returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in China, South Korea and Taiwan.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class I Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore, its performance does not reflect the expenses associated with the active management of an actual portfolio.

Fund Snapshot
We believe company fundamentals and managements’ ability to create value drive share prices over the long-term in emerging markets. We seek to take advantage of opportunities created when investors primarily focus on near-term sentiment and macroeconomic risk factors while ignoring fundamental company research. We buy companies trading well below our conservative estimate of their long-term value and favor quality companies with what we believe are sustainable competitive advantages and high or improving returns on capital.

Performance

Janus Emerging Markets Fund’s Class I Shares returned 9.05% for the 12-month period ended September 30, 2012. The Fund’s benchmark, the MSCI Emerging Markets Index, returned 16.93%.

Portfolio Manager Addition

Hiroshi Yoh was named a co-portfolio manager for Janus Emerging Markets Fund in August, joining co-portfolio managers Matt Hochstetler and Wahid Chammas. Yoh, who joined Janus in 2011, also serves as the portfolio manager of Janus Asia Equity Fund. He has 23 years of financial industry experience and previously served as chief investment officer and a portfolio manager with Tokio Marine Asset Management International. He has also served as president at Franklin Templeton Investment Management Co. (Japan) and held several research and portfolio management positions at Daiwa International Capital Management Co.

Market Overview

Global equity markets produced strong returns following quantitative easing measures by central banks in the U.S. and Europe. The approval of another bailout of Greece and the successful conclusion of a Greek debt restructuring along with general lessening of worries over European sovereign debt also helped sentiment. Inflation in many emerging markets, such as Brazil and China, began to decline along with slower GDP growth. The slower economic growth was healthy in that it has allowed inflation to come within a more moderate range. India rebounded late in the period on hopes that governmental gridlock would loosen. It was hoped a likely credit downgrade of India’s debt would be a catalyst for reform efforts in the country. Higher oil prices gave a boost to the Middle East region, while the election of a new president in Mexico raised hopes for labor reforms in that country.

Performance Overview

The Fund underperformed due largely to our holdings in materials, industrials and health care. Individually, Chariot Oil & Gas weighed the most on performance. The U.K.-based energy firm focused on exploration in Namibia, suffered from disappointing well results.

Turquoise Hill Resources, formerly Ivanhoe Mines, also weighed on results. The Canada-based mining company saw its CEO and six other directors resign in April as part of an equity financing agreement with Rio Tinto, the company’s major shareholder. In May, the stock suffered again when Mongolia passed a law restricting foreign companies from controlling key assets. We believe the company’s world-class mine in Mongolia continues to be undervalued by the market. We also believe Rio Tinto, which acquired a 51% ownership in the company earlier in 2012, will provide the necessary expertise to develop the mine, which is expected to starting producing high-grade copper early next year.

Another detractor, Adani Enterprises, a conglomerate involved in coal mining and power generation, declined due to relative weakness in the Indian equity market and lack of progress in government approvals for some of Adani’s projects. Using an integrated approach involving coal mining, coal logistics and power generation to power transmission, Adani is uniquely positioned, in our view, to better mine domestic coal and transport it from the Eastern India coal belt to the Western India power plants via its rail and port facilities.

Contributors were led by our holdings in telecommunication services and consumer staples. Individually, Samsung was our largest contributor. Among our top five holdings, Samsung continued to expand its market share in smart phones globally and benefited from several product launches. While we recognize the company’s U.S. patent dispute with Apple represents a risk, we do not believe it will lead to a ban of Samsung

products in the U.S. and that it will remain a global leader in smart phones. We consider the company to be both a price leader and a technology leader. The company’s highly diversified earnings sources and the sustainability of its high-margin structure, despite cyclical exposure, support its earnings power. We believe the quality of its earnings, growth, balance sheet and dividend policies surpass global standards.

Another top five holding, Taiwan Semiconductor Manufacturing Co. (TSMC) also aided performance. The company reported results that were at the top end of estimates for its revenues, operating profits and earnings. We like TSMC’s leading market position in foundry, or third-party manufacturing of semiconductor chips. We consider the company a leader in both manufacturing efficiencies and research and development, which makes it well suited to address the growing demand for smaller chip sets that require its leading-edge foundry technology.

Finally, oil and gas exploration and production company Karoon Gas Australia benefited from a successful farm down (selling a share of rights over the prospect to other companies and share investment costs and technological challenges of getting the oil out of the ground) of its Brazilian offshore development sites and successful exploration in the Browse Basin located off the northwest coast of Australia. We believe the company will have success in it exploration campaign in offshore Brazil in the coming year.

Derivatives

During the period, we used currency derivatives to hedge existing currency exposures and swaps to access markets in which we were not trading locally either due to our risk policies or an inability to trade locally. We also executed sales and purchases of puts, calls, and futures to hedge existing equity exposures and potentially gain attractive risk/reward exposures, and sold puts on non-existing positions to hedge other similar securities. In aggregate, these positions negated each other and thus had no impact on performance. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Outlook

While economic growth has slowed in emerging markets, we think China will still manage to produce over 7% GDP growth in 2013 and believe the transition to a new leadership will provide constructive policies for growth. In general, we continue to believe the urbanization of millions of people will provide an attractive growth backdrop and with valuations remaining modest in most of the largest emerging markets, we remain optimistic for the medium-term returns for the asset class. We also think that companies with sustainable competitive moats, growing earnings and strong free cash flow generation will provide better long-term investment results.

Thank you for your investment in Janus Emerging Markets Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), real estate investment trusts (“REITs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Janus Emerging Markets Fund held approximately 12.6% and 10.4% of its total investments in Brazilian and South Korean securities, respectively, as of September 30, 2012, and the Fund may have experienced significant gains or losses due, in part, to its investments in Brazil and South Korea. While holdings are subject to change without notice, the Fund’s returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in Brazil and South Korea.

The Fund invests in REITs which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class I Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore, its performance does not reflect the expenses associated with the active management of an actual portfolio.

Janus Global Life Sciences Fund (unaudited)

Fund Snapshot
We take a global approach to identify high quality or improving businesses in the life sciences sector trading at a discount to our estimate of intrinsic value. We believe the rapidly growing global health care sector offers fertile opportunities for differentiated research. We believe what sets us apart is the quality of our team, the depth of our research and our commitment to delivering superior long-term results for our clients.

Andy Acker
portfolio manager

Performance Overview

Janus Global Life Sciences Fund’s Class T Shares had a good year, rising 36.34% during the 12-month period ended September 30, 2012. This was significantly ahead of the Fund’s primary benchmark, the S&P 500 Index, which returned 30.20%. The Fund also significantly outperformed the MSCI World Health Care Index, the Fund’s secondary benchmark, which rose 25.93% during the period.

Sector Overview

The health care sector benefited from its defensive characteristics in the face of ongoing uncertainty in Europe and the upcoming “fiscal cliff” (a legislatively mandated deadline on a series of tax and spending policies) in the U.S. Interest in the sector was bolstered by increased dividends and share repurchases and several better-than-expected new product launches. Merger and acquisition activity further spurred investor interest as companies took advantage of low interest rates to make highly accretive acquisitions. This also drew attention to some of our favored innovative biotechnology companies as potential buyout targets.

Investment Strategy

The Fund seeks to uncover opportunities that span the life sciences spectrum, including stocks in the biotechnology, pharmaceuticals, health care services, and medical technology arenas. Our bottom-up fundamental approach utilizes extensive proprietary research in an effort to discover the best investment ideas across the globe.

Portfolio Composition

The Fund includes companies that can be categorized into three conceptual groups: core growth, emerging growth and opportunistic investments. In general, about half of the portfolio is invested in core growth holdings (companies with dominant franchises that generate strong, consistent free cash flow). Emerging growth companies (those with new products that we believe can drive earnings acceleration) represent 20-30% of the portfolio. The remaining weighting consists of opportunistic investments, exemplified by companies suffering from what we feel are short-term issues that should resolve over time.

Stocks That Aided Returns

Many of the Fund’s top contributors were concentrated in the biotechnology sector and fit into one of our key themes: investing in companies addressing high unmet medical needs. Examples include two of our top individual contributors, Regeneron Pharmaceuticals and Gilead Sciences.

Regeneron’s stock rose after the company raised guidance for its drug Eylea following better-than-expected sales. Eylea is a next generation drug for wet age-related macular degeneration (AMD), the leading cause of blindness for the elderly. We believe Eylea has potency, cost and convenience advantages over the current standard of care, which has led to a better than expected uptake in the market. The company also benefited from advancement of another novel product for cholesterol lowering into the final stages of clinical testing.

Gilead Sciences received U.S. Food and Drug Administration (FDA) approval to market its HIV drug, Stribild, and priced it higher than market expectations. We believe this should support continued growth for the company’s high margin HIV franchise. Beyond that, Gilead’s emerging hepatitis C franchise widened its lead due to competitor setbacks. When Gilead acquired a key hepatitis C asset through its acquisition of Pharmasset in 2011, investors reacted negatively. Today, there is better appreciation for the product and its strong sales potential. We believe Gilead’s combination of highly active compounds represent one of the most promising new treatment regimens for hepatitis C, which afflicts 3% of the world’s population.

Pharmacy benefit manager (PBM) Express Scripts was another key contributor. We think the company’s

(unaudited)

acquisition of fellow PBM, Medco Health Solutions, could generate significant cost savings and would make Express Scripts the dominant provider of PBM services. We believe PBMs are well positioned to benefit from the wave of patent expirations of branded drugs that is currently underway, and from the rapid growth of specialty pharmaceuticals in the coming years.

Stocks That Weighed on Returns

Detractors were led by biotechnology holding Targacept. Despite highly promising proof of concept data for a novel treatment for refractory depression, late stage clinical trials failed to confirm a therapeutic benefit, leading to a significant decline in the shares. Our “value at risk” approach prompted us to reduce our position size in front of this binary event, but we nevertheless exited the position at a loss.

InterMune’s shares suffered from higher than expected reimbursement hurdles in Europe for its lead drug, Esbriet, used in the treatment of pulmonary fibrosis, a chronic lung disease. Although we believe pulmonary fibrosis remains a high unmet medical need, we think the sales ramp in Europe could take longer than initially expected. We continue to believe the stock has significant upside, especially if a confirmatory trial allows for a launch into the large U.S. market, where adoption could be more rapid.

Finally, Chelsea Therapeutics weighed on performance. The biotechnology holding declined significantly on concerns that FDA approval for its drug to treat some of the symptoms of Parkinson’s disease may be delayed or not approved. We continue to believe the drug has a chance for approval, although we think it’s likely additional studies will be required.

Risk Management

The Fund continues with its “value at risk” approach as part of a comprehensive risk management framework. This approach focuses our attention on downside risks, especially those arising from binary events (such as clinical trial announcements or regulatory decisions) that can lead to significant share price volatility. In practice, this means we limit the position size of any one holding so that, in a worst-case scenario, the estimated adverse impact from a particular event should not exceed 1% of the Fund’s performance. The Fund may also utilize options and futures contracts in an attempt to mitigate risks and enhance the performance of the portfolio.

Please see the Derivative Instruments section in the “Notes to Financial Statements” for derivatives used by the Fund.

Looking Ahead

The significant run-up in health care stocks could make them vulnerable to profit-taking, but we believe the outlooks for the stocks we own remain positive. Managed care is one segment that has not performed well due to investor fears over health care reform. We feel those worries are overdone and have found companies trading at attractive free cash flow multiples with good growth prospects.

Among portfolio changes, we sold our positions in several large pharmaceutical companies that had performed well for the Fund, but either faced patent expiration challenges or suffered disappointments with new drug development. We used the proceeds to invest in what we believe are high quality growth companies, such as Mead Johnson, a global leader in nutritional products, and Perrigo, the dominant provider of store brand over-the-counter pharmaceuticals.

Thank you for your continued investment in Janus Global Life Sciences Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund invests in certain industry groups, which may react similarly to market developments (resulting in greater price volatility), and may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.

Janus Global Research Fund (unaudited)

Fund Snapshot
We are bottom-up, fundamental investors. We believe a deep, independent research process and high conviction investing will deliver exceptional results.
Team-Based Approach
Led by Jim Goff,
Director of Research

Performance Overview

We are pleased with Janus Global Research Fund Class T Shares’ 20.42% absolute return, for the twelve months ended September 30, 2012; however, we are disappointed with the weak relative returns. Our performance was worse than the 23.02% return of the MSCI World Growth Index. We also slightly underperformed the 20.98% return of our secondary benchmark, the MSCI All Country World Index.

While the past year was not our best, we continue to be pleased with the performance of the portfolio over the past three, five and seven years. In February, the Class D Shares of the Fund received the Lipper Award for the Best Global Multi-cap Fund for the five-year period ending December 31, 2011, based on consistency of strong risk-adjusted returns. Fifty Global Multi-cap Growth Funds were eligible for this award for the five-year period. This is exactly our objective, so we were thrilled to receive this recognition.

Proposed Fund Merger

Janus is proposing to merge Janus Global Research Fund and Janus Worldwide Fund, subject to SEC review and approval by shareholders of Janus Global Research Fund. If approved, anticipated end of January 2013, Janus Worldwide Fund’s name will change to Janus Global Research Fund, the benchmark will be the MSCI World Index, and the Fund will be managed by Janus’ research analysts, led by James Goff, applying the same investment strategies and restrictions of Janus Global Research Fund.

Director of Research Comments on Environment

2012 and the prior two calendar years have largely followed the same pattern – a promising start, followed by mid-year misery due largely to Europe, followed by a stronger finish. The first three months of calendar 2012 were strong based on the European Central Bank’s (ECB) Long-Term Refinancing Operation (LTRO) program, providing downside protection to Europe, and a perceived bottoming of the Chinese economy. Equity markets promptly rolled over from April to June based on further slowing and uncertainty in the U.S and China and continued dysfunction in Europe. Valuations, investor sentiment and the market bottomed in June and the “Sell in May and Go Away” slogan gave way to “Buy in June and Get Rich Soon.” With valuations at such low levels, it only took a bit of good news in the form of the Federal Reserve’s third round of quantitative easing, QE3, and bond buying by ECB to rally the MSCI World Growth Index 14.1% from its low in June to the end of September.

The outflows from equities and into bonds since the Lehman Crisis have been of historic proportions. We need to understand, though, that bad headlines are the friend of long-term investors putting money to work. I believe the outflow from equities into bonds is going to end badly for investors. We are finding lots of opportunities we like in the current market. And while high dividend yielding stocks have done well as investors chase for yield, we see attractive valuations particularly in growing companies that are reinvesting for growth as opposed to paying big dividends.

The focus of equity markets on safety and yield has led to the outperformance of larger capitalization and higher yielding companies. Our underexposure to such stocks was a headwind to our performance relative to our index over the past twelve months.

As always, our approach is long term and fundamental. We strive to find great businesses with long duration growth that will create value for shareholders. Investors are focused, probably too much so, on macroeconomic, political, and systemic issues in the global economy. Time horizons are short among investors. It is our hope and expectation that some progress will be made on the issues of deficits, elections and growth in China, Europe and the U.S. in the coming 12 months, calmer markets will prevail and investors will focus more on what we focus on – the long term.

Sector Views

In communications, content owners achieved healthy inflationary pricing despite some contentious battles with distributors this summer. This validates our view that content’s value is still increasing for both consumers and distributors. We believe the value of content will continue rising as it is viewed over new platforms and in international markets, where we see strong subscriber growth for pay-TV platforms. Lately, we have been encouraged by content owners’ ability to capture

Janus Global & International Funds | 33

Janus Global Research Fund (unaudited)

advertising revenue for the content they offer on digital platforms by including the digital content in their upfront bundle sales to advertisers. We expect these multiplatform buys to become more meaningful over the next several years.

For consumer, back-to-school sales got off to a solid start in August. This supports our view that consumer spending continues to be in a growth mode, though at a sub-par annualized pace. The consumer still faces too many headwinds to expect robust growth in U.S. consumer spending in the fourth quarter. In this slow-growth environment, high-quality brands able to differentiate themselves have been able to gain market share.

Janus’ energy team thinks oil prices will remain at their current elevated levels and may even grind their way higher into next year. While oil production rose over the last six months – as Libyan production resumed and Saudi Arabia increased production – total oil inventory dropped for Organization for Economic Co-operation and Development (OECD) countries. This has kept the oil market tight. Going forward, we do not believe we will face a global slowdown severe enough to significantly reduce oil prices. We also believe fears the U.S. could drive oil prices down by flooding the global market are overblown. While horizontal drilling has allowed the U.S. to increase oil production for the first time in decades, the cost of that drilling remains high.

The financials team expects low growth in Europe, but the worst case scenario for the region – break up of the European Union (EU) – appears increasingly unlikely. Unfortunately, the austerity measures struggling countries put in place have choked off growth. The economic environment has also taken its toll on banks. Loan demand remains weak and the regulatory environment continues to hamper profits. However, stock valuations for European banks imply significantly lower returns than banks actually eked in the third quarter of 2012.

In health care, the failure of some high-profile, late-stage clinical trials to treat Alzheimer’s and hepatitis C reaffirmed our view that large-cap pharmaceutical companies are poor investments. We believe there are few commercially important product candidates in these companies’ late-stage pipelines and management will continue to rationalize poor drug development choices in an attempt to create future growth. The recent failures – which we had anticipated – offer a case in point. Many late-stage products face the additional risk of launching into an environment in which good generic alternatives already exist. For most of these new offerings, there is simply not enough innovation to command a substantial price premium, rapid uptake or a disproportionate market share.

Economic conditions continue to deteriorate in China, but our industrials team is starting to see light at the end of the tunnel. Two of the main indicators we monitor for the region – electricity production and rail freight volumes – have yet to turn positive. However, our outlook for China has improved. We see early signs that expansionary policies taken by the Chinese government this spring are starting to flow through the economy. Bank lending has turned up, and purchasing and restocking by Chinese companies have also accelerated. We believe the Chinese economy will start to reaccelerate in the fourth quarter and that 2013 will be a better year for profit growth.

As the pace of change in technology quickens, adaptability is increasingly vital to the prolonged success of technology companies. One of the quickest changes taking shape is the switch in online activity from desktops to mobile phones and tablets. However, the increase in data transmission is starting to clog mobile networks. In coming years, mobile carriers will have to ramp up capital expenditures and build out infrastructure to handle the increased data load. Consumers and businesses have also adopted several other trends faster than expected, including digital credit card payments and increased analytics capabilities.

Performance Overview

Our holdings in technology, industrials and energy weighed the most on performance, while our holdings in communications, financials and health care contributed. On a country basis, our holdings in India and the U.S. were the largest detractors, while holdings and underweight in Japan were the largest contributors.

Individually, India’s Jain Irrigation Systems, a manufacturer of micro-irrigation systems, was the largest detractor. The stock declined after the company reported a loss in its latest quarter. We exited our position. While we continue to like the company’s long-term opportunity in irrigation, we felt the near-term risks on implementing a new finance program to attract cash-strapped farmers as well as ongoing political paralysis in India, which has delayed subsidy payments, were too significant.

Staying in India, Adani Enterprises, a conglomerate involved in coal mining and power generation, also weighed on performance. The stock declined due to relative weakness in the Indian equity market and lack of progress in government approvals for some of Adani’s projects. Using an integrated approach involving coal mining, coal logistics and power generation to power

(unaudited)

transmission, Adani is uniquely positioned, in our view, to better mine domestic coal and transport it from the Eastern India coal belt to the Western India power plants via its rail and port facilities.

Social gaming company Zynga was also a key detractor. A decision by Facebook to de-emphasize gaming on its platform significantly impacted Zynga. We are assessing our thesis on the social gaming company in light of this change.

Individual contributors were led by Apple, the Fund’s largest holding. The world’s largest mobile device and computer maker benefited from strong earnings reported earlier in the period, driven by significant iPhone and iPad sales, as well as the release its latest version of its iPhone late in the period. Apple also initiated its first dividend and share repurchase program during the year. We think Apple continues to have strong opportunities as it attracts new and potentially long-term subscribers and it increases its addressable market as it offers products with lower price points. Apple remained reasonably valued, in our view, so we increased our position.

LyondellBasell Industries was also a significant contributor. The large chemical producer has a cost advantage because the primary input to its production process is natural gas, a commodity that has experienced considerable price pressure due to excess supply. We also feel the company’s new management team is return-on-capital driven and disciplined on investing in its business.

Finally, pharmacy benefit manager (PBM) Express Scripts aided performance. We think the company’s acquisition of fellow PBM, Medco Health Solutions, could generate significant cost savings and would make Express Scripts the dominant provider of PBM services. We believe PBMs are well positioned to benefit from the wave of patent expirations of branded drugs that is currently underway, and from the rapid growth of specialty pharmaceuticals in the coming years.

Thank you for your investment in Janus Global Research Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”) and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class A Shares, Class C Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

February 28, 2005 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the indices. The indices are unmanaged and are not available for direct investment; therefore, their performance does not reflect the expenses associated with the active management of an actual portfolio.

Maris joined Janus from Northern Trust, where he managed U.S., international and global large-cap strategies for institutional and retail clients. He has 14 years of investment management experience including stints at Columbia Management Group and Putnam Investments as well as Northern Trust. Maris will work hand-in-hand with Janus’ team of equity analysts to identify what we consider the best ideas across sectors throughout the world.

Investment Strategy

The Fund remains a high-conviction stock-picking strategy. Looking forward, we plan to invest in 40-70 companies we think represent the best investments from around the world, regardless of geography and across the market capitalization spectrum. We focus on companies with attractive free-cash-flow growth profiles relative to their current valuations, trustworthy management teams and competitive advantages in their businesses. Because we seek excess returns through stock selection, sector weightings generally will not materially diverge from the benchmark weightings. We expect turnover of 50% per year and maximum position sizes of 5%. Additionally, we seek to mitigate liquidity risk by appropriately sizing positions.

Investment Environment

Many of the fears of a global financial crisis emanating from the potential dissolution of the eurozone receded following the European Central Bank’s (ECB) commitment to act as lender of last resort in September. Similarly, German Chancellor Angela Merkel’s support for the ECB’s action demonstrated the key players were unwilling to let the eurozone dissolve. These actions supported our view that a panic leading to runs on banks and sovereign credits was highly unlikely and spurred rallies in equity markets globally, particularly European financials tied to sovereign concerns and European cyclicals hurt by weak demand. Emerging market companies, particularly in China for which Europe is their largest export market, also benefited. This phenomenon led to a virtuous cycle: stronger exports out of China to Europe help other emerging market countries which export to China. The acceptance of an eventual return to normalcy also unlocked value in cyclical stocks by reinforcing the notion current earnings are cyclically weak, and not permanently impaired.

Performance discussion

The Fund significantly underperformed its benchmark due largely to our holdings in the information technology, materials and consumer discretionary sectors. These were partially offset by the relative contribution of our energy holdings. On a country basis, our holdings in the U.S. and Canada weighed the most on performance, while our holdings in Japan were the primary contributors.

Individually, Turquoise Hill Resources, Baoxin Auto Group and EVA Precision Industrial Holdings were the largest individual detractors. All three were sold as part of the portfolio manager transition.

Contributors were led by Cobalt International Energy, Isuzu Motors and Prudential. Isuzu was sold by the previous manager. Cobalt, a U.S. company, reported a significant discovery in one of its West African offshore wells. We

continue to like the oil-focused exploration and production company based on its development prospects.

Prudential also had strong gains during the period. The U.K. insurer benefited late in the period from a favorable regulatory ruling involving capital requirements for its overseas operations. Earlier, the company’s shares rose as part of a general rebound in the financial sector and a strong earnings report driven by better-than-expected results in Asia. Prudential has one of the best long-term growth profiles of any financial services stocks in the world, in our view.

Derivatives

During the period, the previous portfolio manager used options, futures, swaps and forward exchange contracts. In aggregate, these positions detracted from the Fund’s performance during the period. The current portfolio manager plans to use derivatives on a more limited basis relative to the previous manager. Please see the Derivative Instruments section in the “Notes to Financial Statements” for derivatives used by the Fund.

Outlook

We believe the U.S. remains attractive from several perspectives including its strengthened financial system and recovering residential real estate market. Improving home prices are an important factor in consumer wealth. However, unemployment remains stubbornly high, and if higher taxes are implemented, we anticipate investing and consumption will decline. We believe Europe is marginally more attractive based on the political will demonstrated in addressing its sovereign debt crisis. Improvement in Europe should directly benefit emerging markets, which have been unfairly penalized in the risk-off investing environment. Additionally, once the Chinese leadership transition occurs, we expect the Chinese government will be more likely to accelerate economic growth.

Thank you for your continued investment in Janus Global Select Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund’s performance may be affected by risks that include those associated with nondiversification, investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), derivatives, and short sales. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class A Shares, Class C Shares, Class R Shares, and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the indices. The indices are unmanaged and are not available for direct investment; therefore, their performance does not reflect the expenses associated with the active management of an actual portfolio.

Fund Snapshot
We seek to identify strong businesses with sustainable competitive advantages and improving returns on capital. We believe what sets us apart is the depth of our research, our willingness to focus our investments where we feel we have a research edge, and our commitment to delivering superior long-term results for our clients.

Brad Slingerlend

Performance Overview

During the 12 months ended September 30, 2012, Janus Global Technology Fund’s Class T Shares returned 22.86%. By comparison, the Fund’s primary benchmark, the S&P 500 Index, returned 30.20% while the Fund’s secondary benchmark, the MSCI World Information Technology Index, returned 25.23%.

Market Environment

Global technology stocks generated strong absolute returns during the period. Gains were strongest during the first quarter of 2012 when supply chain semiconductor stocks bounced off cyclical lows and investors took advantage of low valuations in large cap technology companies. After retrenching during the second quarter due to slowing economic growth and ongoing worries over the European sovereign debt crisis, technology stocks rallied sharply again over the final month along with global indices following central bank actions in both Europe and the U.S.

Despite the strong performance of technology stocks, technology spending was mixed. In enterprise spending, financial companies, the U.S. federal government and Europe in general were weak, although outside of those segments it was better than expectations. PC and laptop sales were also soft ahead of the Windows 8 launch later this year. However, virtualization of the data center continues to be a growth area since it can represent significant savings for companies. Within the consumer segment, spending on mobile products continued unabated. Communication equipment was another area of strength as carriers increase capital expenditures to build out infrastructure to handle higher data loads. Semiconductor manufacturers and semiconductor equipment providers among other supply chain companies saw sales remain flat due to weak global demand, other than in mobile devices.

Portfolio Manager Comments

We often speak about the important growth of smart phones, mobile computing and apps for consumers and businesses. However, there is another interesting story for technology playing out in the automotive and industrial sectors of the economy where we see opportunity in several semiconductor and electronic connector (a device used to transmit an electric signal between two integrated circuits) stocks. Semiconductors have traditionally been tough businesses which lead shareholders down a rocky road. Combine this with a tough macroeconomic environment and one finds semiconductor stocks sitting at the bottom rung of the trailing 12-month performance ladder. However, when we look at the data, we see growth over the past decade averaging around 7% while both margins and returns on invested capital are increasing. Meanwhile, valuation levels have come down around two thirds compared to a decade ago. What has changed materially is the composition of growth within the total available semiconductor market. For example, our analysis shows that the consumer segment has not grown over the past five years while communications, industrial and automotive growth has more than offset weak consumer performance.

If you think about your own life, this might make some sense. Electronics is pushing deeper into the world all around us – from the cars we drive to the appliances in our kitchen. The holy grail of semiconductor investing is to find a company that participates in this secular, long-duration, growth while not participating in the steep price declines that tend to accompany and facilitate this growth. This is what we think we’ve done with the large weighting towards companies that sell electronic connectors within the portfolio: Amphenol and TE Connectivity.

Connectors are in everything. Their total available market is actually bigger than the market for the types of chips made by Intel. Connectors represent a relatively small part of a device’s total bill of materials so they don’t tend to be subject to undue pricing pressure. Further, they tend to be one of the last parts in the design process – meaning

there are often only one to two sources a company can buy from. Competition remains fragmented, offering additional growth for companies that can find attractive acquisition candidates. Finally, as electronics push deeper into the world around us, so do connectors and increasing units tends to translate into increasing revenues, profits and returns. Couple this with attractive valuations and this makes a pretty good recipe in our opinion.

We also see similar opportunities in semiconductors. Two of our largest holdings in the industry, Atmel and ON Semiconductor, have been disappointing holdings over the past year. However, we continue to see opportunity here. Industrial represents Atmel’s largest end market for their programmable microcontroller products. Microcontrollers act as the electronic brain inside of what’s called embedded electronics. Atmel offers one of the most respected microcontroller platforms in the industry, in our view. ON Semiconductor fits more into the “special situation” category. We see the opportunity for ON’s acquisition of Sanyo Semiconductor to significantly boost earnings in a more normalized global environment – especially in the auto and communications end markets.

While the consumer electronics devices in your life might be converging onto a few must have tools like smart phones and tablets, the proliferation of electronic components into automotive and industrial applications is growing rapidly.

Derivatives

We used puts and calls on individual securities during the period in an attempt to limit the Fund’s decline during market sell-offs. We also used swaps and forward exchange contracts. These positions were a net contributor to relative performance. Over time we expect to use derivatives to take advantage of underlying volatility in the technology sector with the goal of enhancing long term returns for investors. Please see “Notes to Financial Statements” for information about the hedging techniques used by the Fund.

Detractors from Performance

A decision by social networking company Facebook to de-emphasize gaming on its platform significantly impacted Zynga. We are currently assessing our thesis on the social gaming company in light of this change.

Facebook also weighed on performance. The company’s business model shift from desktops to mobile devices occurred quicker than we thought with negative consequences for its revenues in the short term. While we continue to monitor the company’s transition, we decided to exit our position.

Finally, semiconductor maker Atmel traded lower after the company lowered revenue guidance and investor concerns increased over future demand for its microcontrollers used in mobile touchscreens. Industrials represent Atmel’s largest end market for its programmable microcontroller products, which act as the electronic brain inside of embedded electronics. Atmel offers one of the most respected microcontroller platforms in the industry, in our view. The company’s products also enable touch functionality in tablets and other mobile devices. Its touch business has become more competitive, but we continue to see significant opportunities ahead for the company with the new Windows 8 platform for tablets.

Contributors to Performance

Among individual contributors, Apple was the most significant. The world’s largest mobile device and computer maker benefited from strong earnings reported earlier in the period, driven by significant iPhone and iPad sales, and the release its latest version of its iPhone. Apple also initiated its first dividend and share repurchase program during the year. We think Apple continues to have strong opportunities as it attracts new and potentially long-term subscribers and it increases its addressable market as it offers products with lower price points. Apple remained reasonably valued, in our view, so we increased our position.

E-commerce company eBay also recorded strong gains following good earnings reports. We continue to like the online marketplace and payment company’s long-term growth prospects. We feel the company is innovating both its online payment service PayPal and marketplace businesses beyond what is valued by the stock’s price. In particular, we think eBay’s open platform for commerce and payments is best positioned to benefit from accelerating multi-channel commerce in which increasingly online will be used to generate offline in-store demand.

Finally, Amphenol aided performance. We think the company has a strong competitive position with its relatively low-cost, uniquely-designed electronic connectors that are unlikely to be replaced once it is included in a product (autos, computers etc.), giving it high barriers to entry. Its diversified customer base and good margins are also appealing to us.

Thank you for your investment in Janus Global Technology Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), derivatives, and short sales. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund may at times have significant exposure to certain industry groups, which may react similarly to market developments (resulting in greater price volatility). The Fund also may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares, and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Performance Overview

Janus International Equity Fund’s Class I Shares returned 14.33% over the 12-month period ended September 30, 2012, while its primary benchmark, the MSCI EAFE Index, returned 13.75% and its secondary benchmark, the MSCI All Country World ex-U.S. Index, returned 14.48% during the period.

Market Overview

Global equities rallied significantly during the period following a sell-off in the third quarter of 2011. The European Central Bank’s (ECB) decision to inject liquidity through its Long Term Refinancing Operation took a significant amount of fear out of the market, which rose strongly in early 2012. During the second quarter of 2012 and continuing until late in the period, stocks were weak due to concerns of slowing global growth, particularly in China, and renewed worries over the European sovereign debt crisis. However, equity markets charged higher in September following the ECB’s announcement that it would buy sovereign debt to reduce the borrowing costs of peripheral European countries. We interpreted this move as a means of buying time until a period of economic growth can provide Europe a backdrop against which it can solve its debt problems. Additional Chinese stimulus measures also aided the rebound in equities late in the period.

Performance Discussion

The Fund outperformed its primary benchmark led by our holdings in information technology and materials, which more than offset the relative underperformance of our holdings in consumer discretionary and health care. On a country basis, our holdings and underweight in Japan were the largest contributors, while our holdings and underweight in Australia led detractors.

Individually, chemical company LyondellBasell Industries was the most significant contributor. Prices for ethane, a raw material used in the production of ethylene, dropped significantly, improving profitability for the company. LyondellBasell has a cost advantage since the primary input to its production process is natural gas, a commodity that has experienced considerable price pressure due to excess supply. We also feel the company’s management team is return-on-capital driven and disciplined in investing in its business. Lyondell announced a special dividend during the period and bought back its high-cost debt with cash and refinanced some of it at lower costs, all of which were value creating moves in our view.

Prudential also had strong gains during the period. The U.K. insurer benefited late in the period from a favorable regulatory ruling involving capital requirements for its overseas operations. Earlier, the company’s shares rose as part of a general rebound in the financial sector and a strong earnings report driven by better-than-expected results in Asia. A core Fund holding, Prudential has one of the best long-term growth profiles of any financial services stocks in the world, in our view.

In technology, semiconductor equipment provider ASML Holdings was the most significant contributor. The stock rose on news that Intel plans to take a 15 percent stake in the company and fund efforts to accelerate the launch of a new product. We think the deal underscores ASML’s competitive advantage as the only vendor able to deliver cutting-edge, advanced lithography tools, which are necessary for semiconductor manufacturing companies to produce cost competitive semiconductor devices. We believe that ASML’s continued market share gains in the lithography area will lead to levels of free-cash-flow above what the market currently expects.

Individual detractors were led by Chinese travel company Ctrip International, which experienced margin pressures on some of its business lines from competitors seeking to gain market share. We do not believe such competition will negatively impact Ctrip materially long term due its strong market position. We think Ctrip is well positioned to benefit from a burgeoning travel industry. As GDP per capita continues to grow in China, domestic and international travel will increase as well. Ctrip has a

competitive advantage with its large network of sales agents who collect cash and issue tickets for air travel and hotels. We also think it will benefit from the Chinese government’s continued strong promotion of domestic travel.

Yamada Denki, a Japanese electronics retailer, also suffered after one of its near-bankrupt competitors was effectively acquired by another company and refinanced. Since this action significantly altered the competitive landscape for Yamada, we decided to sell our position.

Finally, Brazilian oil and gas exploration and production company OGX Petroleo e Gas Participacoes weighed on performance. The company reported a much lower flow rate from a well than it had projected. Since lower production would likely reduce current cash flow, investors questioned OGX’s ability to fund future expansion. We continue to believe in the long-term asset value of the company’s properties located offshore of Brazil, but also recognize the credibility issue the company’s management faced following the disappointment.

Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion regarding the use of forward currency contracts by the Fund.

Outlook

We think the easing measures China began implementing in May will be evident in the country’s fourth quarter 2012 or first quarter 2013 GDP growth numbers. Additionally, the completion of China’s leadership change should help start some of the infrastructure projects that have been put on hold awaiting the changeover. In the U.S., the housing market remained very strong and we think the economy overall is on a path to recovery. We believe companies are nearing a period in which they will increase capital spending and hiring. The U.S. Federal Reserve’s third round of quantitative easing should help sustain the ongoing recovery.

In Europe, German manufacturing orders appeared to have bottomed and should rebound in the next three to six months. Similarly, we think Germany’s business confidence index is near a bottom and should reverse in early 2013. Thus, we see the potential for a stronger economic outlook in 2013, which would allow Europe to gain momentum in addressing its budget deficits and overall government debt issues. Thus, we see an improving macro environment in 2013 that should allow stock picking to be the main driver of relative performance.

Thank you for your investment in Janus International Equity Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The expense ratios for Class N Shares are estimated.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund may invest in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares, Class I Shares, Class R Shares, and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of each respective share class of the predecessor fund, calculated using the fees and expenses of each respective share class accounting for, when applicable and permitted, any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s and predecessor fund’s Class I Shares, calculated using the fees and expenses of Class D Shares without the effect of any fee and expense limitations or waivers.

Class N Shares of the Fund commenced operations on May 31, 2012. The performance shown for periods prior to May 31, 2012 reflects the historical performance of a similar share class of the Fund and predecessor fund.

Class T Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of the predecessor fund’s Class I Shares, calculated using the fees and expenses of Class T Shares without the effect of any fee and expense limitations or waivers.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class I Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

November 30, 2006 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

Janus Overseas Fund (unaudited)

Fund Snapshot
I believe that company fundamentals drive share prices over the long-term. I use intensive, fundamental research to make high-conviction investments.

Brent Lynn
portfolio manager

Performance Overview

During the 12-month period ended September 30, 2012, Janus Overseas Fund’s Class T Shares returned 3.55%. Its primary benchmark, the MSCI All Country World ex-U.S Index returned 14.48%, and its secondary benchmark, the MSCI EAFE Index, returned 13.75%.

Although absolute performance was positive during the period, the Fund significantly underperformed its benchmark indices for the second year in a row. I am very disappointed with the short-term performance of the Fund. Despite the recent poor performance, my investment approach has not changed, and I remain optimistic about the attractive valuations and long-term prospects for the companies in our Fund. Today’s risk averse markets create tremendous opportunities to buy strong franchises on sale around the world. In this environment, I have concentrated the Fund into our highest conviction ideas. When investors take a long-term view and become more comfortable owning risk assets, I believe the Fund can once again perform to my expectations and to the expectations of my fundholders.

Market Update

Although markets rebounded modestly from depressed levels, the macroeconomic and political environment remained difficult. Amid the macro uncertainty, markets bifurcated between the greatly loved stocks and the very much unloved. Favored were sectors and countries perceived as defensive. Index returns underplay the impact; within countries and sectors we saw a wide performance gap between perceived defensive companies and companies with less near-term visibility in their businesses. For example, within the industrial sector, industrial gas companies, typically with predictable near-term revenues and cash flows, generally outperformed industrial stocks with more volatile earnings such as autos or airlines.

Stocks may have overreacted, in my view, but the uncertainty is not without cause. With a looming fiscal cliff in the United States, a leadership change and slowing economy in China, Indian political inertia and corruption scandals, and the saga of the European sovereign debt crisis, markets had much to digest. The political fighting in Europe was most troubling as it raised fears that excessive government debt levels in a few European countries could spark a global financial crisis.

Austerity programs in Europe and businesses unwilling to take risks kept global economic growth below my expectations. In emerging markets, political issues added to a slowdown already impacted by poor demand in developed markets. I believe, however, that emerging markets have significantly better short-term and long-term growth prospects and stronger sovereign balance sheets than developed economies, yet the stock markets underperformed most European markets over the past 12 months. In dollar terms, the underperformance is even greater. I believe this emerging market relative weakness stems primarily from a low level of risk tolerance among investors.

Portfolio Positioning

While always opportunistic, Janus Overseas Fund took a particularly contrarian approach over the past few years. I added significant investments in depressed financials, cyclicals, and emerging market stocks. This approach achieved some success in prior years, but in the 2011-12 environment of investor risk aversion, contrarian investing clearly has not worked.

I am optimistic about the investment climate. In Europe, the European Central Bank (ECB) and national leaders are attempting to address sovereign balance sheet problems with a much broader approach than before. The ECB is creating a framework to support the sovereign debt markets of troubled countries, such as Spain and Italy, if those countries restructure their economies and government finances. This framework certainly does not solve Europe’s problems, but it can give troubled countries the time to make painful but necessary adjustments. In the U.S., after the election, I believe there is the possibility of a

significant debt reduction compromise between the two parties. Even if a comprehensive deal proves too difficult, a compromise package to limit the impact of a fiscal cliff is realistic. In China, once the leadership transition has been completed in November, I expect to see resumption of the reform process to resume, further government stimulus and an acceleration of private and public sector investment.

My optimism about the medium and long-term potential for Janus Overseas Fund, however, is not based on the macro environment. It is based on the potential I see in our individual holdings. I have met with most of our top companies over past months and our analyst team has met with them much more frequently, as well as with their competitors and customers. I believe that the underlying health of the businesses and the long-term prospects are much better than their stock prices imply. Many of our companies are cyclical, with revenues and cash flows sensitive to the global macro environment, but these businesses are not vaporizing. In most cases, their competitive advantages are increasing, they are still generating significant cash flow, and the long-term prospects remain attractive. I can’t predict when the market’s risk appetite will return and investors will consider these long-term factors but I am convinced that eventually stock market valuations will reflect the business values I see in our companies.

My strategy is to concentrate the Fund in our highest conviction ideas. I maintained large positions in some of our favorite international companies such as Li & Fung, a global leader in sourcing logistics for retailers; Reliance Industries, a leading Indian energy conglomerate; BBVA, a leading bank in Spain and Latin America; Petroleo Brasileiro (Petrobras), one of the world’s fastest growing large oil companies; and Nintendo, one of the world’s leading games companies. Emerging market underperformance for the second year in a row led me to increase the Fund’s overall weight in emerging markets during the period

I decreased our exposure to U.S. stocks when we sold or reduced Ford, Bank of America and Yahoo. The U.S. holdings that remain are special situations with compelling valuations.

Detractors from Performance

Relative to its primary benchmark, the MSCI All-Country World ex-U.S. Index, the Fund’s larger exposure to emerging markets hurt performance during the period, including holdings in India and Brazil. In developed markets, stocks held in Canada, Hong Kong and the UK were significant negative contributors to relative performance. On a sector basis, the Fund’s investments in energy, industrials, and consumer discretionary hurt relative performance.

Currency detracted from the Fund’s absolute and relative performance during the period because of weakening emerging market currencies and corresponding underexposure to outperforming developed market currencies such as the Australian dollar and British pound. The Fund’s hedge against a weakening Japanese yen exposure marginally helped performance. I hedged most of our yen exposure because I felt Japan’s high level of government debt would eventually lead to a weaker yen.

India-based power, port, and coal conglomerate Adani Enterprises was the biggest detractor during the period. Concerns about power pricing, coal contracts, slowing Indian economic growth, and the inability of the Indian government to solve the country’s huge problems in the coal and electricity sectors pressured the stock. I believe that the company’s integrated business model across the power supply chain in India gave Adani Enterprises significant long-term competitive advantages and growth opportunities. In addition, I was encouraged by recent moves by the Indian government to finally address key issues in the power sector. I maintained a significant position in Adani Enterprises during the period.

Canadian oil and gas exploration company Niko Resources was the second largest detractor during the period. The stock fell with concerns about relations with the Indian government and some operational shortfalls, among other issues. I believed that the stock price implied minimal value for Niko’s Indian assets as well as exploration opportunities in Indonesia. I maintained our position in Niko during the period but continue to monitor the company’s exploration progress.

Brazil-based oil and gas company OGX Petroleo e Gas Participacoes was the third largest detractor during the period. The stock fell after the company reported disappointing flow rates from new fields and reduced expectations for oil production over the next few years. I believed that OGX was taking action to mitigate some of the flow rate declines and that the stock valuation did not reflect the company’s long-term production profile and exploration potential offshore Brazil. I added to our position during the period but continue to monitor the company’s production and exploration results.

Contributors to Performance

Hong Kong-based China Overseas Land and Investment, a leading residential property developer in China, was the

72 | SEPTEMBER 30, 2012

(unaudited)

largest positive contributor to performance during the period. China Overseas Land’s competitive advantages from scale, brand, balance sheet, and project execution positioned the company for strong volume growth despite a challenging environment for property development in China, in my view. I believed that the company’s advantages and growth were sustainable, but I cut this long-term holding based on valuation.

U.S.-based airline, Delta Air Lines, was the second largest positive contributor to performance. Strong operations, merger synergies, and continued industry capacity discipline allowed the company to generate solid cash flows even in a difficult economic and oil price environment. I believed Delta’s cash flow generation potential had not been fully appreciated by the market. The stock remained a large holding during the period.

Netherlands-based semiconductor lithography equipment producer ASML Holding was the third largest positive contributor to performance. ASML’s technology lead continued to widen, as evidenced by the company’s dominant market share in leading edge lithography equipment and close partnerships with the world’s largest semiconductor manufacturers. I believed ASML’s technology dominance would continue for many years but I sold our position based on valuation.

Derivatives

In aggregate, derivatives added modestly to performance during the period. In addition to the currency hedge on the Japanese yen mentioned earlier, the Fund also very selectively utilized swaps and options during the period. Reasons for using these instruments included hedging downside risks, achieving market access, and establishing positions more quickly. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Investment Strategy and Outlook

I am disappointed in the underperformance of the Fund over the past two years. I did not foresee this continued difficult environment for global risk assets. I too am a shareholder of Janus Overseas Fund, but more importantly, I am a steward of your money. I take my responsibility very seriously. I recognize that you have trusted me and Janus with your hard-earned savings.

I recognize the near term problems for the global economy but remain optimistic as I look out further. Sovereign debt issues, fiscal cliffs, and political uncertainty will not forever hold back global growth. New technologies, urbanization, infrastructure development, trade, and the desire of people around the world for a better life will once again drive economic growth.

Conviction always is important but in difficult times, it is critical. My conviction in the portfolio comes from our team’s tremendous, in-depth fundamental research. The choppy market means opportunities to buy great companies at bargain prices. I believe that owning these businesses and staying the course will ultimately lead to solid long-term returns.

Thank you for your continued investment in Janus Overseas Fund.

Returns quoted are past performance and do not guarantee future results; current performance may be lower or higher. Investment returns and principal value will vary; there may be a gain or loss when shares are sold.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

See important disclosures on the next page.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The expense ratios for Class N Shares are estimated.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

Janus Overseas Fund held approximately 13.1% and 18.2% of its investments in Brazilian and Indian securities, respectively, as of September 30, 2012, and the Fund may have experienced significant gains or losses due, in part, to its investments in Brazil and India. While holdings are subject to change without notice, the Fund’s returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in Brazil and India.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares, Class R Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

Class N Shares of the Fund commenced operations on May 31, 2012. The performance shown for periods prior to May 31, 2012 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

May 5, 1994 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

Actual expenses paid reflect only the inception period for Class N Shares (May 31, 2012 to September 30, 2012). Therefore, actual expenses shown are lower than would be expected for a six-month period. Actual expenses are equal to the net annualized ratio of 0.44% for Class N Shares multiplied by the average account value over the period, multiplied by 123/366 (to reflect the period); however, hypothetical expenses are multiplied by 183/366 (to reflect the one-half year period). Expenses include the effect of applicable fee waivers and/or expense reimbursements, if any. See Notes to Financial Statements for details regarding waivers and/or reimbursements.

Janus Worldwide Fund (unaudited)

Fund Snapshot
Janus Worldwide Fund invests globally, seeking companies that we believe have a sustainable competitive advantage, high or improving returns on capital and long-term growth. We invest where we believe we have differentiated research in an effort to deliver strong risk-adjusted results over the long term.

George Maris
portfolio manager

Performance Overview

During the 12-month period ended September 30, 2012, Janus Worldwide Fund’s Class T Shares returned 17.44%. Its benchmark, the MSCI World Index, returned 21.59%. The Fund’s secondary benchmark, the MSCI All Country World Index, returned 20.98%.

Proposed Fund Merger

Janus is proposing to merge Janus Global Research Fund and Janus Worldwide Fund, subject to SEC review and approval by shareholders of Janus Global Research Fund. If approved, anticipated end of January 2013, Janus Worldwide Fund’s name will change to Janus Global Research Fund and the Fund will be managed by Janus’ research analysts, led by James Goff, applying the same investment strategies and restrictions of Janus Global Research Fund. Janus Worldwide Fund will also replace its performance and accounting history with that of Janus Global Research Fund. Janus’ proposal to merge the funds is based largely on the similarities of the funds’ investment objectives, strategies and policies. Additional information regarding these changes is expected to be sent to shareholders of Janus Worldwide Fund prior to the merger.

Economic Update

Many of the fears of a global financial crisis emanating from the potential dissolution of the eurozone receded following the European Central Bank’s (ECB) commitment to act as lender of last resort in September. Similarly, German Chancellor Angela Merkel’s support for the ECB’s action demonstrated the key players were unwilling to let the eurozone dissolve. These actions supported our view that a panic leading to runs on banks and sovereign credits was highly unlikely and spurred rallies in equity markets globally, particularly European financials tied to sovereign concerns and European cyclicals hurt by weak demand. Emerging market companies, particularly in China for which Europe is their largest export market, also benefited. This phenomenon led to a virtuous cycle: stronger exports out of China to Europe help other emerging market countries which export to China. The acceptance of an eventual return to normalcy also unlocked value in cyclical stocks by reinforcing the notion current earnings are cyclically weak, and not permanently impaired.

Performance Overview

The Fund underperformed largely due to our holdings in energy, financials and industrials. These positions were partially offset by the positive contribution of our holdings in consumer discretionary, telecommunication services and health care. On a country basis, our holdings in the U.S. and India were the most significant detractors, while our holdings and underweight in Japan were the top contributors.

Individually, India’s Jain Irrigation Systems weighed the most on performance. The stock declined after the company reported a loss in its latest quarter. We reduced our position. While we continue to appreciate the company’s long-term opportunity in irrigation, we also recognized the near-term risks on implementing a new finance program to attract cash-strapped farmers as well as ongoing political paralysis in India, which has delayed subsidy payments.

In financials, MGIC Investment Corp. was a key detractor. The mortgage insurer declined significantly after reporting a loss in its latest quarter. Investors are concerned the nascent recovery in housing defaults will not continue, endangering the company’s balance sheet. Further, Freddie Mac wants the company to increase its capital base in order to underwrite Freddie Mac mortgages in the future. We believe MGIC will benefit from the ongoing recovery in the U.S. housing market and possesses the balance sheet resources to continue to operate profitably. While its balance sheet is weak due to loan defaults emanating from the housing crisis, business undertaken following the crisis has been high quality and exceptionally profitable. If profitability of the new business grows and the losses from old policies decline, MGIC should

Janus Global & International Funds | 81

generate strong returns. Given the need for mortgage insurers, the limited number of market participants and MGIC’s strong market share, MGIC’s risk/reward profile is attractive in our view.

Technology holding Atmel also weighed on performance. The semiconductor manufacturer traded lower after the company lowered revenue guidance, giving rise to concerns over future demand for its microcontrollers used in mobile touchscreens. The industrial market represents Atmel’s largest end market for its programmable microcontroller products, which act as the electronic brain inside of embedded electronics. Atmel offers one of the most respected microcontroller platforms in the industry, in our view. The company’s products also enable touch functionality in tablets and other mobile devices. While the touch business is increasingly competitive, we see significant opportunities for the company with the new Windows 8 platform for tablets.

Contributors were led by Comcast. The company is using its leading position in cable to grow market share and returns. In the cable side of its business, it is offering more attractive entertainment options to grow and retain customers. These options include rolling out new set top boxes with a more intuitive and helpful feature set, contracting with key content providers, such as Disney, to ensure high-quality content will be available to its customers, and facilitating content use with traditional cable television as well as broadband video. We appreciate these actions should lead to greater customer capture, allowing Comcast to further penetrate its customer base with additional offerings in broadband and telecommunications, in addition to new products like home security. The NBC Universal acquisition is also generating significant synergies via cost reductions and better content experiences. Lastly, management is aggressively employing a disciplined capital allocation program, where new investments and acquisitions are considered along with a commitment to material buybacks and dividends.

Regeneron Pharmaceuticals was also a key contributor. The biotechnology company benefited from strong sales of its new drug Eylea. We view Eylea as a next generation drug for wet age-related macular degeneration (also known as wet AMD), the leading cause of blindness for the elderly. The drug appears more effective than the current leading treatment, may reduce by half the number of injections patients receive, and is less expensive, all of which should significantly increase its rate of adoption in the market.

Finally, SBA Communications benefited along with other wireless communications tower companies from strong data usage that has driven demand for tower space. Telecommunications companies have also been competing for network quality, which generally has a direct impact on how much leasing they do with tower companies like SBA. We believe the company has a long runway for potential growth.

Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Investment Outlook and Positioning

The U.S. remains attractive from several perspectives including its strengthened financial system and recovering residential real estate market. Improving home prices are an important factor in consumer wealth. However, unemployment remains stubbornly high, and if higher taxes are implemented, we anticipate investing and consumption will decline. Europe is marginally more attractive based on the political will demonstrated in addressing its sovereign debt crisis. Improvement in Europe should directly benefit emerging markets, which have been unfairly penalized in the risk-off investing environment. Additionally, once the Chinese leadership transition occurs, we expect the Chinese government will be more likely to accelerate economic growth.

With respect to positioning, we increased our exposure to European industrial stocks we consider to be high-quality companies punished due to the cyclical nature of their respective industries. These companies represent attractive opportunities to us given their strong competitive advantages, attractive industries, and compelling stock prices. Adding these companies marginally lowered our exposure to the U.S.

Thank you for your continued support of Janus Worldwide Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class A Shares, Class C Shares, Class R Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations or waivers.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for periods prior to February 16, 2010 reflects the historical performance of the Fund’s predecessor share class.

Class I Shares of the Fund commenced operations on July 6, 2009. The performance shown for periods prior to July 6, 2009 reflects the historical performance of a similar share class of the Fund.

If each share class of the Fund had been available during periods prior to its commencement, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of each share class reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers. Please refer to the Fund’s prospectuses for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

May 16, 1991 is the date used to calculate the since–inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the indices. The indices are unmanaged and are not available for direct investment; therefore, their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

The ratio would be 1.43% and 1.43%, respectively, without the inclusion of the non-recurring expense adjustment.
(10)	As a result in the recharacterization of dividend income to return of capital, the Ratio of Net Investment Income/(Loss) to Average Net Assets has been reduced by 0.04%. The adjustment had no impact on total net assets or total return of the class.

Notes to Financial Statements

The following section describes the organization and significant accounting policies and provides more detailed information about the schedules and tables that appear throughout this report. In addition, the Notes to Financial Statements explain the methods used in preparing and presenting this report.

1.  Organization and Significant Accounting Policies

Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund and Janus Worldwide Fund (individually, a “Fund” and collectively, the “Funds”) are series funds. The Funds are part of Janus Investment Fund (the “Trust”), which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The financial statements include information for the fiscal year ended September 30, 2012. The Trust offers forty-five funds which include multiple series of shares, with differing investment objectives and policies. The Funds invest primarily in equity securities. Each Fund in this report is classified as diversified, as defined in the 1940 Act, with the exception of Janus Global Select Fund, which is classified as nondiversified.

Each Fund in this report offers multiple classes of shares in order to meet the needs of various types of investors. Each class represents an interest in the same portfolio of investments. Certain financial intermediaries may not offer all classes of shares.

Class A Shares and Class C Shares are generally offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. The maximum purchase in Class C Shares is $500,000 for any single purchase.

Class D Shares are generally no longer being made available to new investors. The Shares are available only to investors who hold accounts directly with the Janus funds and to immediate family members or members of the same household of an eligible individual investor. The Shares are not offered through financial intermediaries.

Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, and bank trust platforms, as well as certain retirement platforms. Class I Shares are also available to certain institutional investors including, but not limited to, corporations, certain retirement plans, public plans, and foundations/endowments.

Class N Shares, which commenced May 31, 2012, are generally available only to financial intermediaries purchasing on behalf of 401(k) plans, 457 plans, 403(b) plans, Taft-Hartley multi-employer plans, profit-sharing and money purchase pension plans, defined benefit plans and nonqualified deferred compensation plans.

Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms.

Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with Janus Capital Management LLC (“Janus Capital”) or its affiliates to offer Class S Shares on their supermarket platforms.

Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with Janus Capital or its affiliates to offer Class T Shares on their supermarket platforms.

The following accounting policies have been followed by the Funds and are in conformity with accounting principles generally accepted in the United States of America.

Investment Valuation

Securities are valued at the last sales price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities traded on over-the-counter (“OTC”) markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees. Short-term securities with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Short positions shall be valued in accordance with the same methodologies, except that in the event that a last sale price is not available, the latest ask price shall be used instead of a bid price. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect as of the daily close of

136 | SEPTEMBER 30, 2012

the New York Stock Exchange (“NYSE”). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the Funds are identified between the closing of their principal markets and the time the net asset value (“NAV”) is determined, securities may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Funds’ Trustees. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a nonsignificant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. Restricted and illiquid securities are valued in accordance with procedures established by the Funds’ Trustees.

Investment Transactions and Investment Income

Investment transactions are accounted for as of the date purchased or sold (trade date). Dividend income is recorded on the ex-dividend date. Certain dividends from foreign securities will be recorded as soon as the Trust is informed of the dividend, if such information is obtained subsequent to the ex-dividend date. Dividends from foreign securities may be subject to withholding taxes in foreign jurisdictions. Interest income is recorded on the accrual basis and includes amortization of premiums and accretion of discounts. Gains and losses are determined on the identified cost basis, which is the same basis used for federal income tax purposes. Income, as well as gains and losses, both realized and unrealized, are allocated daily to each class of shares based upon the ratio of net assets represented by each class as a percentage of total net assets.

Expenses

Each Fund bears expenses incurred specifically on its behalf, as well as a portion of general expenses, which may be allocated pro rata to each Fund. Each class of shares bears expenses incurred specifically on its behalf and, in addition, each class bears a portion of general expenses, which are allocated daily to each class of shares based upon the ratio of net assets represented by each class as a percentage of total net assets. Expenses directly attributable to a specific class of shares are charged against the operations of such class.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held at the date of the financial statements. Net unrealized appreciation or depreciation of investments and foreign currency translations arise from changes in the value of assets and liabilities, including investments in securities held at the date of the financial statements, resulting from changes in the exchange rates and changes in market prices of securities held.

Currency gains and losses are also calculated on payables and receivables that are denominated in foreign currencies. The payables and receivables are generally related to foreign security transactions and income translations.

Foreign currency-denominated assets and forward currency contracts may involve more risks than domestic transactions, including currency risk, political and economic risk, regulatory risk and equity risk. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar.

Dividend Distributions

The Funds generally declare and distribute dividends of net investment income and realized capital gains (if any) annually. The majority of dividends and capital gains distributions from the Funds may be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

The Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It is quite common for these dividends to exceed the REITs’ taxable earnings and profits, resulting in the excess portion of such dividends being designated as a return of

Janus Global & International Funds | 137

Notes to Financial Statements (continued)

capital. If the Funds distribute such amounts, such distributions could constitute a return of capital to shareholders for federal income tax purposes.

Federal Income Taxes

No provision for income taxes is included in the accompanying financial statements as the Funds intend to distribute to shareholders all taxable investment income and realized gains and otherwise comply with Subchapter M of the Internal Revenue Code applicable to regulated investment companies.

In accordance with the Financial Accounting Standards Board (“FASB”) guidance, the Funds adopted the provisions of “Income Taxes.” These provisions require an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that, based on the technical merits, have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense on the Statements of Operations.

These provisions require management of the Funds to analyze all open tax years, as defined by the Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the fiscal year ended September 30, 2012, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examinations in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Modernization Act”) was signed by the President. The Modernization Act is the first major piece of legislation affecting Regulated Investment Companies (“RICs”) since 1986 and it modernizes several of the federal income and excise tax provisions related to RICs. Some of the enacted provisions include:

New capital losses may now be carried forward indefinitely, and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for eight years, and carried forward as short-term capital, irrespective of the character of the original loss.

The Modernization Act contains simplification provisions, which are aimed at preventing disqualification of a RIC for “inadvertent” failures of the asset diversification and/or qualifying income tests. Additionally, the Modernization Act exempts RICs from the preferential dividend rule, and repeals the 60-day designation requirement for certain types of pay-through income and gains.

Finally, the Modernization Act contains several provisions aimed at preserving the character of distributions made by a fiscal year RIC during the portion of its taxable year ending after October 31 or December 31, reducing the circumstances under which a RIC might be required to file amended Forms 1099 to restate previously reported distributions.

Except for the simplification provisions related to RIC qualification, the Modernization Act was effective for taxable years beginning after December 22, 2010. The provisions related to RIC qualification are effective for taxable years for which the extended due date of the tax return is after December 22, 2010.

Restricted Cash

As of September 30, 2012, Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Technology Fund and Janus Overseas Fund had restricted cash in the amounts of $82,000, $1,759,450, $110,000 and $87,158,986, respectively. The restricted cash represents collateral received in relation to futures and options contracts invested in by the Funds at September 30, 2012. The restricted cash is held at the Funds’ custodian, State Street Bank and Trust Company. The carrying value of the restricted cash approximates fair value.

Valuation Inputs Summary

In accordance with FASB guidance, the Funds utilize the “Fair Value Measurements” to define fair value, establish a framework for measuring fair value, and expand disclosure requirements regarding fair value measurements. The Fair Value Measurement Standard does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. This standard emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. Various inputs are used in determining the value of the Funds’ investments defined pursuant to this standard. These inputs are summarized into three broad levels:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Prices determined using other significant observable inputs. Observable inputs are inputs that reflect the assumptions market participants would use in pricing a security and are developed based on

138 | SEPTEMBER 30, 2012

market data obtained from sources independent of the reporting entity. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others.

Debt securities are valued in accordance with the evaluated bid price supplied by the pricing service and generally categorized as Level 2 in the hierarchy. Securities traded on OTC markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees and are categorized as Level 2 in the hierarchy. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value and are categorized as Level 2 in the hierarchy. Other securities that may be categorized as Level 2 in the hierarchy include, but are not limited to, preferred stocks, bank loans, American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs), warrants, swaps, investments in mutual funds, OTC options, and forward contracts. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. These are generally categorized as Level 2 in the hierarchy.

Level 3 – Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable or deemed less relevant (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the factors market participants would use in pricing the security and would be based on the best information available under the circumstances.

For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used in employing valuation techniques such as the market approach, the income approach, or the cost approach, as defined under the FASB Guidance. These are categorized as Level 3 in the hierarchy.

There have been no significant changes in valuation techniques used in valuing any such positions held by the Funds since the beginning of the fiscal year.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of inputs used as of September 30, 2012 to value the Funds’ investments in securities and other financial instruments is included in the “Valuation Inputs Summary” and “Level 3 Valuation Reconciliation of Assets” (if applicable) in the Notes to Schedules of Investments.

In May 2011, the FASB issued Accounting Standards Update, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements.” The Accounting Standards Update requires disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Funds shall provide quantitative information about the significant unobservable inputs used in the fair value measurement. To meet the objective of the quantitative disclosure, the Funds may need to further disaggregate to provide more meaningful information about the significant unobservable inputs used and how these inputs vary over time.

The Funds are not required to create quantitative information to comply with this disclosure requirement if quantitative unobservable inputs are not developed by the Funds when measuring fair value (for example, when a Fund uses prices from prior transactions or third-party pricing information without adjustment). However, when providing this disclosure, the Funds cannot ignore quantitative unobservable inputs that are significant to the fair value measurement and are reasonably available to the Funds.

In addition, the Accounting Standards Update requires the Funds to provide a narrative sensitivity disclosure of the fair value measurement changes in unobservable inputs and the interrelationships between those unobservable inputs for fair value measurements categorized with Level 3 of the fair value hierarchy.

The following table shows transfers between Level 1 and Level 2 of the fair value hierarchy during the fiscal year ended September 30, 2012.

	Transfers Out

Janus Asia Equity Fund	$	1,646,689

valuation adjustment factor at the beginning of the fiscal year and no factor was applied at the end of the fiscal year.

The Funds recognize transfers between the levels as of the beginning of the fiscal year.

The significant unobservable inputs used in the fair value measurements categorized within Level 3 of the fair value hierarchy include, but are not limited to:

•  Liquidity – changes to the liquidity market can have an impact on venture capital investments if additional cash is needed

•  Market conditions – market conditions may impact revenues, potential customers, the ability to raise cash, and the business climate

•  Company specific news – product development progress, staff changes, etc. may indicate progress or setbacks in development of the company

•  Portfolio manager/analyst commentary – valuation/net present value models, conference feedback, conversations with management, and market overviews add data to be used in fair value reviews

•  Other – grey market trading activity and sector performance can provide fair value price indications

In general, any significant changes in any of those inputs in isolation could result in a significantly lower or higher fair value measurement.

The following table summarizes the valuation techniques used and unobservable inputs developed by the Global Pricing Committee to determine the fair value of certain, material Level 3 investments for Janus Global Life Sciences Fund. The table does not include Level 3 investments with values derived utilizing prices from prior transaction or third party pricing information without adjustment (e.g., broker quotes, pricing services, net asset values).

** This column represents the directional change in the fair value of the Level 3 investments that would result in an increase from the corresponding input. A decrease to the unobservable input would have the opposite effect. Significant increases and decreases in these inputs in isolation could result in significantly higher or lower fair value measurements.

2.  Derivative Instruments

The Funds may invest in various types of derivatives, which may at times result in significant derivative exposure. A derivative is a financial instrument whose performance is derived from the performance of another asset. The Funds may invest in derivative instruments including, but not limited to: futures contracts, put options, call options, options on future contracts, options on foreign currencies, swaps, forward contracts, structured investments, and other equity-linked derivatives. Each derivative instrument that was held by one or more of the Funds during the fiscal year ended September 30, 2012 is discussed in further detail below. A summary of derivative activity by Fund is reflected in the tables at the end of this section.

The Funds may use derivative instruments for hedging (to offset risks associated with an investment, currency exposure, or market conditions) or for speculative (to seek to enhance returns) purposes. When the Funds invest in a derivative for speculative purposes, the Funds will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. The Funds may not use any derivative to gain exposure to an asset or class of assets in which they would be prohibited by their respective investment restrictions from purchasing

140 | SEPTEMBER 30, 2012

directly. The Funds’ ability to use derivative instruments may also be limited by tax considerations.

Investments in derivatives in general are subject to market risks that may cause their prices to fluctuate over time. Investments in derivatives may not directly correlate with the price movements of the underlying instrument. As a result, the use of derivatives may expose the Funds to additional risks that they would not be subject to if they invested directly in the securities underlying those derivatives. The use of derivatives may result in larger losses or smaller gains than otherwise would be the case. Derivatives can be volatile and may involve significant risks, including, but not limited to, counterparty risk, credit risk, currency risk, equity risk, index risk, interest rate risk, leverage risk, and liquidity risk, as described below.

Derivatives may generally be traded OTC or on an exchange. Derivatives traded OTC, such as options and structured notes, are agreements that are individually negotiated between parties and can be tailored to meet a purchaser’s needs.

OTC derivatives are not guaranteed by a clearing agency and may be subject to increased credit risk. In an effort to mitigate credit risk associated with derivatives traded OTC, the Funds may enter into collateral agreements with certain counterparties whereby, subject to certain minimum exposure requirements, a Fund may require the counterparty to post collateral if the Fund has a net aggregate unrealized gain on all OTC derivative contracts with a particular counterparty. There is no guarantee that counterparty exposure is reduced and these arrangements are dependent on Janus Capital’s ability to establish and maintain appropriate systems and trading.

In pursuit of their investment objectives, each Fund may seek to use derivatives to increase or decrease exposure to the following market risk factors:

•  Counterparty Risk – Counterparty risk is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to a Fund.

•  Credit Risk – Credit risk is the risk an issuer will be unable to make principal and interest payments when due, or will default on its obligations.

•  Currency Risk – Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

•  Equity Risk – Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

•  Index Risk – If the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, a Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

•  Interest Rate Risk – Interest rate risk is the risk that the value of fixed-income securities will generally decline as prevailing interest rates rise, which may cause a Fund’s NAV to likewise decrease, and vice versa.

•  Leverage Risk – Leverage risk is the risk associated with certain types of leveraged investments or trading strategies pursuant to which relatively small market movements may result in large changes in the value of an investment. A Fund creates leverage by using borrowed capital to increase the amount invested, or investing in instruments, including derivatives, where the investment loss can exceed the original amount invested. Certain investments or trading strategies that involve leverage can result in losses that greatly exceed the amount originally invested.

•  Liquidity Risk – Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

Forward Foreign Currency Exchange Contracts

A forward foreign currency exchange contract (“forward currency contract”) is an obligation to buy or sell a foreign currency at a future date at a negotiated rate. The Funds may enter into forward currency contracts for hedging purposes, including, but not limited to, reducing exposure to changes in foreign currency exchange rates on foreign portfolio holdings and locking in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. The Funds may also invest in forward currency contracts for nonhedging purposes such as seeking to enhance returns. The Funds are subject to currency risk in the normal course of pursuing their investment objectives through their investments in forward currency contracts.

The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of

Janus Global & International Funds | 141

Notes to Financial Statements (continued)

the foreign currency in U.S. dollars upon closing a contract is included in “Net realized gain/(loss) from investment and foreign currency transactions” on the Statements of Operations (if applicable).

Forward currency contracts held by the Funds are fully collateralized by other securities, which are denoted on the accompanying Schedules of Investments (if applicable). The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts. Such collateral is in the possession of the Funds’ custodian.

Futures Contracts

A futures contract is an exchange-traded agreement to take or make delivery of an underlying asset at a specific time in the future for a specific predetermined negotiated price. The Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds are subject to interest rate risk, equity risk, and currency risk in the normal course of pursuing their investment objectives through their investments in futures contracts. The Funds may also use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between the values of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Futures contracts are marked-to-market daily, and the daily variation margin is recorded as a receivable or payable on the Statements of Assets and Liabilities (if applicable). When a contract is closed, a realized gain or loss is recorded as “Net realized gain/(loss) from futures contracts” on the Statements of Operations (if applicable), equal to the difference between the opening and closing value of the contract. Generally, futures contracts are marked-to-market (i.e., treated as realized and subject to distribution) for federal income tax purposes at fiscal year-end. Securities held by the Funds that are designated as collateral for market value on futures contracts are noted on the Schedules of Investments (if applicable). Such collateral is in the possession of the Funds’ custodian or with the counterparty broker.

With futures, there is minimal counterparty credit risk to the Funds since futures are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default.

Options Contracts

An options contract provides the purchaser with the right, but not the obligation, to buy (call option) or sell (put option) a financial instrument at an agreed upon price. The Funds may purchase or write covered and uncovered put and call options on swap contracts (“swaptions”), futures contracts, and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds are subject to interest rate risk, liquidity risk, equity risk, and currency risk in the normal course of pursuing their investment objectives through their investments in options contracts. The Funds may use options contracts to hedge against changes in interest rates, the values of equities, or foreign currencies. The Funds may utilize American-style and European-style options. An American-style option is an option contract that can be exercised at any time between the time of purchase and the option’s expiration date. A European-style option is an option contract that can only be exercised on the option’s expiration date. The Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in long-term equity anticipation securities, which are long-term options contracts that can be maintained for a period of up to three years. The Funds may also enter into a swaption contract which grants the purchaser the right, but not the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. Entering into a swaption contract involves, to varying degrees, the elements of credit, market and interest rate risk, associated with both option contracts and swap contracts. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the Funds receive a premium and become obligated to sell or purchase the underlying security at a fixed price, upon exercise of the option. In writing an option, the Funds bear the risk of an unfavorable change in the price of the security underlying the written option. Exercise of an option written by the Funds could result in the Funds buying or selling a security at a price different from the current market value.

When an option is exercised, the proceeds on sales for a written call option, the purchase cost for a written put option, or the cost of the security for a purchased put or call option are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and OTC put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are

different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

Options traded on an exchange are regulated and the terms of the options are standardized. Options traded OTC expose the Funds to counterparty risk in the event that the counterparty does not perform. This risk is mitigated by having a netting arrangement between the Funds and the counterparty and by having the counterparty post collateral to cover the Funds’ exposure to the counterparty.

Holdings of the Funds designated to cover outstanding written options are noted on the Schedules of Investments (if applicable). Options written are reported as a liability on the Statements of Assets and Liabilities as “Options written at value” (if applicable). Realized gains and losses are reported as “Net realized gain/(loss) from written options contracts” on the Statements of Operations (if applicable).

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the options are exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the options are exercised. The risk in buying options is that the Funds pay a premium whether or not the options are exercised. The use of such instruments may involve certain additional risks as a result of unanticipated movements in the market. A lack of correlation between the value of an instrument underlying an option and the asset being hedged, or unexpected adverse price movements, could render the Funds’ hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. There is no limit to the loss the Funds may recognize due to written call options.

Swaps

A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The Funds may utilize swap agreements as a means to gain exposure to certain common stocks and/or to “hedge” or protect their portfolios from adverse movements in securities prices or interest rates. The Funds are subject to equity risk and interest rate risk in the normal course of pursuing their investment objectives through investments in swap contracts. Swap agreements entail the risk that a party will default on its payment obligation to a Fund. If the other party to a swap defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Swap agreements traditionally were privately negotiated and entered into in the OTC market. However, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) of 2010 now permits certain swap agreements to be cleared through a clearinghouse and traded on an exchange or swap execution facility. New regulations under the Dodd-Frank Act could, among other things, increase the cost of such transactions. Swap contracts of the Funds are reported as an asset or liability on the Statements of Assets and Liabilities (if applicable). Realized gains and losses of the Funds are reported in “Net realized gain/(loss) from swap contracts” on the Statements of Operations (if applicable).

Dividend swap agreements involve an exchange by the parties of their respective commitments to pay or right to receive the changes in a dividend index point. The Funds gain exposure by either paying or receiving an amount in respect of an increase or decrease in the change of the relevant dividend index point based on a notional amount. For example, if a Fund took a long position on a dividend index swap, the Fund would receive payments if the relevant index point increased in value and would be obligated to pay if that index point decreased in value.

Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period.

The Funds’ maximum risk of loss for dividend swaps and total return swaps from counterparty risk or credit risk is the discounted value of the payments to be received from/paid to the counterparty over the contract’s remaining life, to the extent that the amount is positive. The risk is mitigated by having a netting arrangement between the Funds and the counterparty and by the posting of collateral to the Funds to cover the Funds’ exposure to the counterparty.

3.  Other investments and strategies

Additional Investment Risk

It is important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in NAV, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude a Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Act which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity (or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

In addition, European markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels, and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal, and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and worldwide sellers of credit default swaps linked to that country’s creditworthiness. These trends have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of all European countries, which in turn may have a material adverse effect on a Fund’s investments in such countries, other countries that depend on European countries for significant amounts of trade or investment, or issuers with exposure to European debt.

Certain areas of the world have historically been prone to and economically sensitive to environmental events such as, but not limited to, hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, tornadoes, mudslides, or other weather-related phenomena. Such disasters, and the resulting physical or economic damage, could have a severe and negative impact on a Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses as they would under normal conditions.

148 | SEPTEMBER 30, 2012

Adverse weather conditions may also have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The extent of a Fund’s exposure to counterparty risk in respect to financial assets approximates its carrying value as recorded on the Fund’s Statement of Assets and Liabilities.

A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby a Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures and options. A Fund intends to enter into financial transactions with counterparties that Janus Capital believes to be creditworthy at the time of the transaction. There is always the risk that Janus Capital’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Emerging Market Investing

Each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging markets.” Investing in emerging markets may involve certain risks and considerations not typically associated with investing in the United States and imposes risks greater than, or in addition to, the risks associated with investing in securities of more developed foreign countries. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Funds’ investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Funds’ investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.

Exchange-Traded Funds

The Funds may invest in exchange-traded funds which generally are index-based investment companies that hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Real Estate Investing

The Funds may invest in equity and debt securities of U.S. and non-U.S. real estate-related companies. Such companies may include those in the real estate industry or real estate-related industries. These securities may include common stocks, preferred stocks, and other equity securities, including, but not limited to, REITs and similar REIT-like entities such as foreign entities that have REIT characteristics.

Short Sales

The Funds may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into short sales against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

The Funds may also engage in other short sales. The Funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the Funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the

Notes to Financial Statements (continued)

lender. No more than 10% of a Fund’s net assets may be invested in short positions (through short sales of stocks, structured products, futures, swaps, and uncovered written calls). The Funds may engage in short sales “against the box” and options for hedging purposes that are not subject to this 10% limit. Although the potential for gain as a result of a short sale is limited to the price at which the Fund sold the security short less the cost of borrowing the security, the potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. There is no assurance the Funds will be able to close out a short position at a particular time or at an acceptable price. A gain or a loss will be recognized upon termination of a short sale. Short sales held by the Funds are fully collateralized by restricted cash or other securities, which are denoted on the accompanying Schedules of Investments (if applicable). The Funds are also required to pay the lender of the security any dividends or interest that accrue on a borrowed security during the period of the loan. Depending on the arrangements made with the broker or custodian, a Fund may or may not receive any payments (including interest) on collateral it has deposited with the broker. The Funds pay stock loan fees, disclosed on the Statements of Operations (if applicable), on assets borrowed from the security broker.

The Funds may also enter into short positions through derivative instruments, such as options contracts, futures contracts, and swap agreements, which may expose the Funds to similar risks. To the extent that the Funds enter into short derivative positions, the Funds may be exposed to risks similar to those associated with short sales, including the risk that the Funds’ losses are theoretically unlimited.

4.  Investment Advisory Agreements and Other Transactions with Affiliates

Each Fund pays Janus Capital an investment advisory fee which is calculated daily and paid monthly. The following table reflects each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate).

			Contractual
			Investment
	Average		Advisory
	Daily		Fee/Base
	Net Assets		Fee (%)
Fund	of the Fund		(annual rate)
Janus Asia Equity Fund		N/A		0.92
Janus Emerging Markets Fund		N/A		1.00
Janus Global Life Sciences Fund		All Asset Levels		0.64
Janus Global Research Fund		N/A		0.64
Janus Global Select Fund		All Asset Levels		0.64
Janus Global Technology Fund		All Asset Levels		0.64
Janus International Equity Fund		N/A		0.68
Janus Overseas Fund		N/A		0.64
Janus Worldwide Fund		N/A		0.60

For Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Research Fund, Janus International Equity Fund, Janus Overseas Fund and Janus Worldwide Fund, the investment advisory fee rate is determined by calculating a base fee and applying a performance adjustment. The base fee rate is the same as the contractual investment advisory fee rate shown in the table above. The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index, as shown below:

Fund	Benchmark Index
Janus Asia Equity Fund		MSCI All Country Asia
		ex-Japan Index
Janus Emerging Markets Fund		MSCI Emerging Markets IndexSM
Janus Global Research Fund		MSCI World Growth Index
Janus International Equity Fund		MSCI EAFE® Index
Janus Overseas Fund		MSCI All Country World
		ex-U.S. IndexSM
Janus Worldwide Fund		MSCI World IndexSM

The calculation of the performance adjustment applies as follows:

Investment Advisory Fee = Base Fee Rate +/- Performance Adjustment

The investment advisory fee rate paid to Janus Capital by each of the Funds listed above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period generally is the previous 36 months, although no Performance Adjustment is made until a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund). When a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund), but

150 | SEPTEMBER 30, 2012

less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. Any applicable Performance Adjustments began January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, January 2012 for Janus Emerging Markets Fund, and August 2012 for Janus Asia Equity Fund.

No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which a Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses, whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. For performance measurement periods prior to July 6, 2009, certain Funds calculated their Performance Adjustment by comparing the performance of Class T Shares (formerly named Class J Shares) against the investment record of each Fund’s respective benchmark index. For periods beginning July 6, 2009, the investment performance of a Fund’s load-waived Class A Shares for the performance measurement period is used to calculate the Performance Adjustment. Because the Performance Adjustment is based on a rolling 36-month performance measurement period, calculations based solely on the performance of a Fund’s load-waived Class A Shares was not fully implemented until July 6, 2012. Prior to that time, the Fund’s performance was compared to a blended investment performance record that includes the Fund’s Class T Shares (formerly named Class J Shares) performance (the prior share class used for performance calculations) for the portion of the performance measurement period prior to July 6, 2009, and the Fund’s load-waived Class A Shares for the remainder of the period. At the conclusion of the transition period, the Fund’s Class T Shares will be eliminated from the Performance Adjustment calculation, and the calculation will be based solely upon a Fund’s load-waived Class A Shares. After Janus Capital determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares, or Class T Shares (formerly named Class J Shares) as the case may be, against the cumulative investment record of the Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable.

It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

The Funds’ prospectuses and statement of additional information contain additional information about performance-based fees. The amount shown as advisory fees on the Statements of Operations reflects the Base Fee Rate plus/minus any Performance Adjustment.

Notes to Financial Statements (continued)

During the fiscal year ended September 30, 2012, the following Funds recorded a Performance Adjustment as indicated in the table below:

	Performance
Fund	Adjustment
Janus Asia Equity Fund	$	(484)
Janus Emerging Markets Fund		(16,712)
Janus Global Research Fund		284,944
Janus International Equity Fund		272,229
Janus Overseas Fund		(16,470,122)
Janus Worldwide Fund		(284,658)

Janus Capital Singapore Pte. Limited (“Janus Singapore”) serves as subadviser to Janus Asia Equity Fund and Janus Emerging Markets Fund. Janus Capital pays Janus Singapore a fee equal to 50% of the advisory fee paid by Janus Asia Equity Fund and 1/3 of the advisory fee paid by Janus Emerging Markets Fund to Janus Capital (calculated after any applicable performance fee adjustment, fee waivers, and expense reimbursements). The subadvisory fee paid by Janus Capital to Janus Singapore adjusts up or down based on each of Janus Asia Equity Fund’s and Janus Emerging Markets Fund’s performance relative to each Fund’s respective benchmark index over the performance measurement period. Janus Singapore has been in the investment management business since 2011 and serves as subadviser to other U.S. registered investment companies and offshore investment funds. Janus Singapore is a wholly-owned subsidiary of Janus Capital.

Janus Services LLC (“Janus Services”), a wholly-owned subsidiary of Janus Capital, is the Funds’ transfer agent. In addition, Janus Services provides or arranges for the provision of certain other administrative services including, but not limited to, recordkeeping, accounting, order processing, and other shareholder services for the Funds.

Certain, but not all, intermediaries charge administrative fees to investors in Class A Shares, Class C Shares, and Class I Shares for administrative services provided on behalf of such investors. These administrative fees are paid by the Class A Shares, Class C Shares, and Class I Shares of the Funds to Janus Services, which uses such fees to reimburse intermediaries. Consistent with the Transfer Agency Agreement between Janus Services and the Funds, Janus Services may negotiate the level, structure, and/or terms of the administrative fees with intermediaries requiring such fees on behalf of the Funds. Janus Capital and its affiliates benefit from an increase in assets that may result from such relationships.

Class D Shares pay an annual administrative services fee of 0.12% of net assets. These administrative services fees are paid by Class D Shares for shareholder services provided by Janus Services.

Janus Services receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class R Shares, Class S Shares and Class T Shares of the Funds for providing or procuring administrative services to investors in Class R Shares, Class S Shares and Class T Shares of the Funds. Janus Services expects to use all or a significant portion of this fee to compensate retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries for providing these services. Janus Services or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to Class R Shares, Class S Shares and Class T Shares of each Fund. Janus Services may keep certain amounts retained for reimbursement of out-of-pocket costs incurred for servicing clients of Class R Shares, Class S Shares, and Class T Shares.

Services provided by these financial intermediaries may include, but are not limited to, recordkeeping, subaccounting, order processing, providing order confirmations, periodic statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, answering inquiries regarding accounts, and other administrative services. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with Janus Capital.

Janus Services is compensated for its services related to Class D Shares, and receives reimbursement for its out-of-pocket costs on all other share classes. Included in out-of-pocket expenses are the expenses Janus Services incurs for serving as transfer agent and providing servicing to shareholders.

Janus Distributors LLC (“Janus Distributors”), a wholly-owned subsidiary of Janus Capital, is the distributor of the Funds. The Funds have adopted a Distribution and Shareholder Servicing Plan (the “Plan”) pursuant to Rule 12b-1 under the 1940 Act. The Plan authorizes payments by the Funds to intermediaries at an annual rate, as determined from time to time by the Board of Trustees, of up to 0.25% of the Class A Shares average daily net assets, of up to 1.00% of the Class C Shares average daily net assets, of up to 0.50% of the Class R Shares average daily net assets, and of up to 0.25% of the Class S Shares average daily net assets. Payments under the Plan are not tied exclusively to actual distribution and shareholder service expenses, and the payments may exceed distribution and shareholder service expenses actually incurred by the Funds. If any of a Fund’s actual distribution and shareholder service expenses incurred during a calendar year are less than

152 | SEPTEMBER 30, 2012

the payments made during a calendar year, the Fund will be refunded the difference. Refunds, if any, are included in “Distribution fees and shareholder servicing fees” in the Statements of Operations.

Janus Capital has agreed to reimburse certain Funds until at least February 1, 2013 by the amount, if any, that such Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding any performance adjustments to management fees, if applicable, class-specific distribution and shareholder servicing fees applicable to Class A Shares, Class C Shares, Class R Shares, and Class S Shares, the administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees for Class A Shares, Class C Shares, and Class I Shares), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, exceed the annual rates noted below. If applicable, amounts reimbursed to the Funds by Janus Capital are disclosed as “Excess Expense Reimbursement” on the Statements of Operations.

Fund	Expense Limit (%)
Janus Asia Equity Fund		1.25
Janus Emerging Markets Fund		1.25
Janus Global Research Fund		1.00
Janus Global Select Fund		0.90
Janus International Equity Fund		1.25
Janus Overseas Fund		0.92
Janus Worldwide Fund		1.00

The Board of Trustees has adopted a deferred compensation plan (the “Deferred Plan”) for independent Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Funds. All deferred fees are credited to an account established in the name of the Trustees. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the Janus funds that are selected by the Trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of September 30, 2012 on the Statements of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statements of Assets and Liabilities. Deferred compensation expenses for the fiscal year ended September 30, 2012 are included in “Non-interested Trustees’ fees and expenses” on the Statements of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. Deferred fees of $96,480 were paid to a Trustee under the Deferred Plan during the fiscal year ended September 30, 2012.

Certain officers of the Funds may also be officers and/or directors of Janus Capital. The Funds’ Chief Compliance Officer and certain other Fund officers may be compensated by the Funds. The Funds reimburse Janus Capital for a portion of the compensation paid to the Chief Compliance Officer and certain compliance staff as well as Janus Capital personnel providing administration services to the Funds. Total compensation of $781,717 was paid to the Chief Compliance Officer and certain compliance staff by the Trust during the fiscal year ended September 30, 2012. Each Fund’s portion is reported as part of “Other Expenses” on the Statements of Operations.

Class A Shares include a 5.75% upfront sales charge of the offering price of the Funds. The sales charge is allocated between Janus Distributors and financial intermediaries. During the fiscal year ended September 30, 2012, Janus Distributors retained the following upfront sales charges:

	Upfront
Fund (Class A Shares)	Sales Charge
Janus Asia Equity Fund	$	651
Janus Emerging Markets Fund		162
Janus Global Life Sciences Fund		5,974
Janus Global Research Fund		3,718
Janus Global Select Fund		1,406
Janus Global Technology Fund		1,117
Janus International Equity Fund		4,662
Janus Overseas Fund		17,586
Janus Worldwide Fund		302

A contingent deferred sales charge (“CDSC”) of 1.00% will be deducted with respect to Class A Shares purchased without a sales load and redeemed within 12 months of purchase, unless waived, as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class A Shares redeemed. During the fiscal year ended September 30, 2012, redeeming shareholders of Class A Shares paid the following CDSCs to Janus Distributors:

Fund (Class A Shares)	CDSC
Janus Global Research Fund	$	1
Janus Global Select Fund		175
Janus International Equity Fund		5
Janus Overseas Fund		5,600

Class C Shares include a 1.00% CDSC paid by redeeming shareholders to Janus Distributors. The CDSC applies to shares redeemed within 12 months of

Janus Global & International Funds | 153

purchase. The redemption price may differ from the net asset value per share. During the fiscal year ended September 30, 2012, redeeming shareholders of Class C Shares paid the following CDSCs:

Fund (Class C Shares)	CDSC
Janus Global Research Fund	$	638
Janus Global Select Fund		1,351
Janus Global Technology Fund		143
Janus International Equity Fund		4,226
Janus Overseas Fund		45,572
Janus Worldwide Fund		12

During the period, a 2.00% redemption fee was imposed on Class D Shares, Class I Shares, Class R Shares, Class S Shares, and Class T Shares of the Funds, as applicable, held for 90 days or less. This fee was paid to the Funds rather than Janus Capital, and was designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Funds’ asset levels and cash flow due to short-term money movements in and out of the Funds. The redemption fee was accounted for as an addition to Paid-in Capital. Effective April 2, 2012, the 2.00% redemption fee charged by the Funds upon the sale or exchange of Class D Shares, Class I Shares, Class R Shares, Class S Shares, or Class T Shares within 90 days of purchase or exchange was eliminated and is no longer being charged by the Funds.

Total redemption fees received by the Funds for the fiscal year ended September 30, 2012 are indicated in the table below:

Fund	Redemption Fee
Janus Asia Equity Fund	$	785
Janus Emerging Markets Fund		3,550
Janus Global Life Sciences Fund		12,169
Janus Global Research Fund		10,121
Janus Global Select Fund		24,433
Janus Global Technology Fund		28,209
Janus International Equity Fund		4,740
Janus Overseas Fund		416,099
Janus Worldwide Fund		13,940

The Funds’ expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such credits or offsets are included in “Expense and Fee Offset” on the Statements of Operations (if applicable). The transfer agent fee offsets received during the fiscal year reduce “Transfer agent fees and expenses” on the Statements of Operations (if applicable). Custodian offsets received reduce “Custodian fees” on the Statements of Operations (if applicable). The Funds could have employed the assets used by the custodian and/or transfer agent to produce income if they had not entered into an expense offset arrangement.

Pursuant to the provisions of the 1940 Act and rules promulgated thereunder, the Funds may participate in an affiliated or nonaffiliated cash sweep program. In the cash sweep program, uninvested cash balances of the Funds may be used to purchase shares of affiliated or nonaffiliated money market funds or cash management pooled investment vehicles. The Funds are eligible to participate in the cash sweep program (the “Investing Funds”). Janus Cash Liquidity Fund LLC is an affiliated unregistered cash management pooled investment vehicle that invests primarily in highly-rated short-term fixed-income securities. Janus Cash Liquidity Fund LLC currently maintains a NAV of $1.00 per share and distributes income daily in a manner consistent with a registered 2a-7 product. There are no restrictions on the Funds’ ability to withdraw investments from Janus Cash Liquidity Fund LLC at will, and there are no unfunded capital commitments due from the Funds to Janus Cash Liquidity Fund LLC. As adviser, Janus Capital has an inherent conflict of interest because of its fiduciary duties to the affiliated cash management pooled investment vehicles and the Investing Funds.

During the fiscal year ended September 30, 2012, Janus International Equity Fund received non-recurring income of $24,135 from an affiliated party.

During the fiscal year ended September 30, 2012, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

5.  Federal Income Tax

The tax components of capital shown in the table below represent: (1) distribution requirements the Funds must satisfy under the income tax regulations; (2) losses or deductions the Funds may be able to offset against income and gains realized in future years; and (3) unrealized appreciation or depreciation of investments for federal income tax purposes (reduced by foreign tax liability).

Other book to tax differences may consist of deferred compensation, derivatives and foreign currency contract adjustments. The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses, if applicable. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

Janus Global & International Funds | 155

Notes to Financial Statements (continued)

The Funds have elected to defer post-October losses and qualified late-year losses as noted in the table below. These losses will be deferred for tax purposes and recognized during the next fiscal year.

Accumulated capital losses noted below represent net capital loss carryovers, as of September 30, 2012, that may be available to offset future realized capital gains and thereby reduce future taxable gains distributions. Under the Regulated Investment Company Modernization Act of 2010, the Funds are permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Losses incurred during these years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may more likely expire unused. Also, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, passive foreign investment companies, net investment losses and capital loss carryovers. Certain permanent differences such as tax returns of capital and net investment losses noted below have been reclassified to paid-in capital.

8.  New Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board issued Accounting Standards Update No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact this update may have on the Funds’ financial statements.

9.  Pending Merger

On August 30, 2012, the Trustees of Janus Global Research Fund approved Janus Capital’s proposal to merge Janus Global Research Fund into Janus Worldwide Fund, effective on or about January 25, 2013. Janus Capital’s proposal to merge the two funds was based largely on similarities of the funds’ investment objectives, strategies and policies, as well as the anticipated expense efficiencies due to the larger asset base of the combined fund after the merger. This merger is subject to approval by the shareholders of Janus Global Research Fund. If the merger is approved, shareholders of Janus Global Research Fund will receive the same class of shares of the combined fund that they hold in Janus Global Research Fund as of the merger date.

Management has evaluated whether any events or transactions occurred subsequent to September 30, 2012 and through the date of issuance of the Funds’ financial statements and determined that there were material events or transactions that would require recognition or disclosure in the Funds’ financial statements as discussed below.

Taking into consideration factors concerning the pending IPO, the fair value of Workday, Inc. (held at September 30, 2012 by Janus Global Technology Fund) has been adjusted in accordance with generally accepted accounting principles required at the period end for financial reporting purposes. As a result, the net asset values and total returns of Janus Global Technology Fund differ from those reflected for shareholder transactions. On October 12, 2012, Workday, Inc. issued an IPO and its fair market value increased 145% compared to the aforementioned fair value. The impacts of October 12, 2012 are not reflected in the September 30, 2012 financial statements of Janus Global Technology Fund. The Fund’s investment in this issuer exposes shareholders to positive and negative performance resulting from this and other events.

Management Fee Evaluation

During 2011, and particularly during November and December, the Boards of Trustees (Trustees) of Janus Investment Fund (JIF) and Janus Aspen Series (JAS) reviewed significant information in connection with considering the continuation of existing investment advisory agreements in effect between Janus Capital Management LLC (JCM) and certain series of JIF and JAS (together, the Janus Funds).¹ In connection with their review, the Trustees engaged an independent fee consultant to assist them in the evaluation of the following fee-related issues:

•  the nature, extent, and quality of JCM’s services provided to the Janus Funds, including fund performance;

•  management fees² (and components thereof) charged by other mutual fund advisers for similar services, including a comparison of total expenses;³

•  management fees (and components thereof) charged to JCM’s institutional and other clients for similar services;

•  costs to JCM and its affiliates of providing services pursuant to the investment advisory agreements;

•  profit margins of JCM and its affiliates from providing those services;

•  possible economies of scale as a fund grows larger; and

•  continued use of performance fees on certain Janus Funds.

On December 8, 2011, the Trustees approved the continuation of the existing investment advisory agreements and related administration agreements for each of the Janus Funds, having determined, in consultation with their independent fee consultant, that the management fees charged by JCM to each of the Janus Funds, in relation to the services provided by JCM, were reasonable.

The following summarizes the findings of the independent fee consultant retained by the Trustees as provided to the Trustees on December 8, 2011.

Summary Findings

Over three years, JCM delivered strong, though declining, performance to the Janus Funds at management fees that are significantly lower than the mean management fees charged by the advisers of comparable mutual funds. For the 36 months ended September 30, 2011, approximately 45% of the Janus Funds were in the top quartile of performance when compared to their respective peer groups established by Lipper, Inc. (“Lipper”) based on total returns, and approximately 62% were in the top two quartiles. For the 12 months ended September 30, 2011, approximately 18% of the Janus Funds were in the top quartile of performance, and approximately 41% were in the top two quartiles. Fifty-five percent of the Janus Funds had a four- or five-star overall rating from Morningstar as of September 30, 2011. Please visit janus.com or call 877-335-2687 for more recent performance information for the Janus Funds.

For the fiscal periods ended December 31, 2010⁴ or March 31, 2011⁵ (together, the “Fiscal Periods”), the total expenses of the Janus Funds were, on average, 15% below the mean total expenses of each fund’s respective Lipper Expense Group and 23% below the mean total expenses for the respective Lipper Expense Universe.

For the Fiscal Periods, the management fees for the Janus Funds were, on average, 8% below the mean management fees for each fund’s respective Lipper Expense Group and 9% below the mean for their respective Lipper Expense Universe.

Within those larger averages, the management fees and total expenses of individual Janus Funds and share classes are reasonable.

The management fees JCM charges to the Janus Funds are also reasonable in relation to the management fees it charges to its institutional and subadvised accounts. Those other accounts have different service and

164 | SEPTEMBER 30, 2012

infrastructure needs. Moreover, the average spread between management fees charged to the Janus Funds and those charged to JCM’s institutional and subadvised accounts is less than the average spread between such management fees charged by other advisers according to recent industry surveys.

The level of profit earned by JCM from managing the Janus Funds appears to be reasonable.

Analysis completed by the independent fee consultant cannot definitively demonstrate or confirm overall economies of scale in the Janus complex. Shareholders are well served by the fee levels and structures in place on the Janus Funds in light of any economies of scale that may be present.

The indices and methodologies used in the calculation of performance fees are appropriate, including for continued use. The use of performance fee adjustments has not had a negative impact on the portfolio management or risk profile of the Janus Funds that have performance fees.

Findings Related to Specific Factors

The following information contains certain conclusions of the independent fee consultant with respect to each of the factors described above:

I. Nature and Quality of Services Provided

JCM provides a number of different services for the Janus Funds and their shareholders ranging from investment management services to various other servicing functions. JCM is a capable provider of those services. JCM has developed a number of institutional competitive advantages that should enable it to provide superior investment and service performance for its clients over the long term. These include:

•  Leading Edge Research – JCM has a research staff that provides a steady stream of proprietary ideas and analytical rigor to the Janus fund managers.

•  Breadth of Research Coverage – JCM has invested in growing its research talent into a number of different market sectors and asset classes. This expanded breadth allows Janus fund managers a broader base of investment options and more opportunities to find undervalued securities.

•  Performance-Focused Culture – JCM has a performance-driven culture combining both strong competitive instincts and collegial cooperation. JCM’s Denver location, away from the major financial centers, can be a positive element in building a strong team and culture.

•  Customer Service-Driven Culture – In their customer service and transfer agency operations, JCM and its affiliates have maintained a strong commitment to service and to measurements that track service performance. JCM has made continual improvements to its website, providing strong web-based service capabilities. As the market has evolved towards advice-driven channels, JCM has evolved its distribution organization and services to support these new channels. JCM continues to add infrastructure to support these new intermediaries.

•  Efficient Cost Structure and Associated Low Total Expenses – JCM has developed an ability to leverage its investment management personnel across larger pools of assets than many other complexes. To the extent lower operating costs at JCM allow for lower management fees or additional investments in investment management, these lower costs can enhance performance of the Janus Funds.

•  Financial Discipline – JCM has shown strong financial discipline in recent years by aggressively managing its costs in the face of declines in revenues. Throughout this process, JCM has continued to invest in its research personnel to maintain its core competence in investment management. Janus has also preserved core capabilities while cutting costs and restructuring its capital structure on a more conservative basis.

•  Quality Trading Infrastructure – JCM maintains trading operations in Denver, London, and Singapore. The U.S. trading personnel are competent, qualified professionals supported by strong systems and market linkages. In particular it was noted that JCM traders are a significant source of advantage for JCM in obtaining best execution on trades.

II. Total Expenses Paid by the Janus Funds vs. Those Paid by Other Mutual Funds

All Janus Funds: As of the Fiscal Periods, the total expenses of each of the Janus Funds were, on average, 15% to 23% below the mean total expenses of comparable funds within a fund’s respective Lipper peer group. In most cases, Janus was below peer expenses for expense components of individual fund segments. There were five key areas where a certain component of Janus average expenses for a given fund category was above peer expenses.

These five areas were (a) Janus Money Market Funds management fees, (b) Janus Specialty Funds non-management expenses, (c) Janus Fixed-Income Funds management fees, (d) Janus Value Funds management fees, and (e) Janus Core Funds nonmanagement expenses. Each of these areas received deeper analysis. The independent fee consultant concluded that, in those

Janus Global & International Funds | 165

Additional Information (unaudited) (continued)

areas where a JCM expense component was above peer expense averages, such variances were reasonable.

Please visit janus.com/info (or janus.com/reports if you hold shares directly with Janus) or call Janus at 877.33JANUS (or 800.525.3713 if you hold shares directly with Janus) for information on Janus Funds’ expenses or to obtain a prospectus or, if available, a summary prospectus that includes a description of such expenses.

Individual Janus Funds (consisting of 239 individual share classes): As of the Fiscal Periods, 113 of the Janus Funds’ share classes had a level of performance versus peers significantly better than the relative level of their expenses versus peers.⁶ Another 58 of the Janus Funds’ share classes were found to have expense ratios that appeared balanced in relation to their performance.⁷ Within this group, individual classes with higher expenses had higher performance; and individual classes with lower expenses had lower performance. Thirteen share classes did not yet have three-year performance histories for evaluation and such classes were categorized based on one-year of returns.⁸ Six share classes were new to 2011 and did not yet have one year of performance history available for analysis. The screening criteria was not applied to these share classes.⁹ Analysis of 49 share classes found that trend lines by fund, recent and planned corrective action, assets under management (AUM) levels, average account sizes and other factors found expenses on these classes to be reasonable.¹⁰

III. Management Fees Paid by Janus Funds vs. Those Paid by Other Mutual Funds

All Janus Funds: The asset-weighted mean management fee paid by the Janus Funds for the Fiscal Periods was 8% below the 0.68% mean management fees of the respective Lipper Expense Group and 9% below the 0.69% mean management fees of the respective Lipper Expense Universe.

Individual Janus Funds (consisting of 235 individual share classes): As of the Fiscal Periods, 119 of the Janus Funds’ share classes had a level of performance versus peers significantly better than the relative level of their management fees versus peers.¹¹ Forty-five classes were found to have management fees that appeared balanced in relation to their performance.¹² Within the latter group, individual classes with higher management fees had higher performance, and individual classes with lower management fees had lower performance. Thirteen share classes did not yet have three-year performance histories for evaluation and were categorized based on one-year returns.⁸ Five share classes were in full management fee waiver typically associated with smaller funds.¹³ Six share classes were new to 2011 and did not have one year of performance history available for analysis. The screening criteria was not applied to these share classes.⁹ Forty-seven share classes received more detailed review. The detailed review of these classes found that trend lines and/or planned corrective actions were likely to result in reasonable fee and service combinations for investors.¹⁴

IV. Management Fees Paid by Janus Funds vs. Those Paid by Other Janus Clients

In addition to managing mutual funds, JCM also provides investment management and services to other types of clients, including institutional/private accounts (also called separate accounts) and subadvised mutual funds. Similar to other asset managers, JCM’s services for these different account types have significant differences, as shown below.

Mutual Funds	Institutional Accounts
Serve a large base of investors	Serve a narrower base of investors
Distributed mostly by intermediaries	Distributed directly
Small shareholder account balances	Large account balances
Standardized pricing/fees	Customized pricing/fees
Standardized reporting	Customized reporting
Offer daily liquidity	Offer less than daily liquidity
Subject to 1940 Act regulation	Not subject to 1940 Act regulation
Extensive regulatory reporting	Limited regulatory reporting
Board oversight	No Board oversight
Class action suits filed	No class action suits filed

Within the industry, pricing for different account types reflects those differences. The independent fee consultant reviewed industry data on institutional account fees and subadvised fees, and analyzed the fee spreads between JCM institutional accounts and their mutual fund counterparts, relative to retail-institutional fee spreads seen across the industry. The independent fee consultant believes that the differential between management fees charged to the Janus Funds by JCM and management fees charged to institutional and subadvised accounts by JCM are reasonable in light of the different levels of services provided.

V. JCM Costs and Profitability

JCM generated profit margins that are in line with other large public advisers. In the opinion of the independent fee consultant, healthy profitability should help investors by ensuring JCM has the continued ability to attract top investment management talent, and a continuing ability to invest in those resources and business activities that produce superior performance.

166 | SEPTEMBER 30, 2012

VI. Possible Economies of Scale

As a manager of a large fund complex, JCM and the Janus Funds may have economies of scale in certain cost elements that can provide benefits as assets grow. Some areas which may have such benefits are:

•  Out of Pocket Expenses – The Janus Funds may share directly in any expense reductions negotiated with third-party service providers.

•  Brokerage Commissions – The Janus Funds share directly in economies of scale through JCM’s negotiation of favorable brokerage commission rates.

•  Other – The Janus Funds can also benefit indirectly from economies of scale through the enhanced levels of resources such economies provide to JCM in its pursuit of performance. One example of this is the addition of research staff as assets grow.

•  Other Fund Nonmanagement Expenses – The Janus Funds may also benefit from a reduction in certain non-management expenses that tend to decline, in terms of basis points, as fund sizes get larger.

There may be diseconomies of scale in certain costs that can work against economies found in other cost elements. Some areas which may have such diseconomies are:

•  large complex legal and regulatory costs; and

•  concentrated fund trading costs.

The independent fee consultant considered various analytical approaches in viewing economies or diseconomies of scale.

VII. Continued Use of Performance Fees on Janus Funds

In assessing whether the continued use of performance fees on certain Janus Funds is appropriate, the independent fee consultant considered (a) the appropriateness of benchmarks used, (b) the appropriateness of the performance calculation methodology, (c) whether any performance-based adjustment had any adverse effect on the management or risk profile of the Janus Funds that have performance fees, and (d) the appropriateness of the continued use of performance-based adjustment structure set out in the advisory agreements. Following this review, the independent fee consultant determined that the continued use of performance fees is appropriate for Janus Funds that charge a performance fee and is in the interests of fund shareholders.

Conclusions

The independent fee consultant concluded that the services provided by JCM and expenses incurred by the Janus Funds over the prior year were reasonable and provide adequate justification for continuation of the Janus Funds’ existing advisory agreements.

When comparing the performance of a Fund with an index, keep in mind that market indices do not include brokerage commissions that would be incurred if you purchased the individual securities in the index. They also do not include taxes payable on dividends and interest or operating expenses incurred if you maintained a Fund invested in the index.

Average annual total returns are quoted for each Fund. Average annual total return is calculated by taking the growth or decline in value of an investment over a period of time, including reinvestment of dividends and distributions, then calculating the annual compounded percentage rate that would have produced the same result had the rate of growth been constant throughout the period. Average annual total return does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or redemptions of Fund shares.

Pursuant to federal securities rules, expense ratios shown in the performance chart reflect subsidized (if applicable) and unsubsidized ratios for the prior fiscal year. The total annual fund operating expenses ratio is gross of any fee waivers, reflecting a Fund’s unsubsidized expense ratio. The net annual fund operating expenses ratio (if applicable) includes contractual waivers of Janus Capital and reflects a Fund’s subsidized expense ratio. Both the total annual fund operating expenses ratio and net annual fund operating expenses ratio are based on average net assets as of the fiscal year ended September 30, 2011. The ratios also include expenses indirectly incurred by a Fund as a result of investing in other investment companies or pooled investments, which are not reflected in the “Financial Highlights” of this report. As a result, these ratios may be higher or lower than those shown in the “Financial Highlights” in this report. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

2.  Schedules of Investments

Following the performance overview section is each Fund’s Schedule of Investments. This schedule reports the industry concentrations and types of securities held in each Fund on the last day of the reporting period. Securities are usually listed by type (common stock, corporate bonds, U.S. Government obligations, etc.) and by industry classification (banking, communications, insurance, etc.). Holdings are subject to change without notice.

The value of each security is quoted as of the last day of the reporting period. The value of securities denominated in foreign currencies is converted into U.S. dollars.

If a Fund invests in foreign securities, it will also provide a summary of investments by country. This summary reports each Fund’s exposure to different countries by providing the percentage of securities invested in each country. The country of each security represents the country in which the company is incorporated. Each Fund’s Schedule of Investments relies upon the industry group and country classifications published by Bloomberg L.P.

2a. Forward Currency Contracts

A table listing forward currency contracts follows each Fund’s Schedule of Investments (if applicable). Forward currency contracts are agreements to deliver or receive a preset amount of currency at a future date. Forward currency contracts are used to hedge against foreign currency risk in the Funds’ long-term holdings.

The table provides the name of the foreign currency, the settlement date of the contract, the amount of the contract, the value of the currency in U.S. dollars and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the change in currency exchange rates from the time the contract was opened to the last day of the reporting period.

2b. Futures

A table listing futures contracts follows each Fund’s Schedule of Investments (if applicable). Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. Futures are used to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, the principal amount, value and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the marked-to-market amount for the last day of the reporting period.

2c. Options

A table listing written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options contracts are contracts that obligate a Fund to sell or purchase an underlying security at a fixed price, upon exercise of the option. Options are used to hedge against

170 | SEPTEMBER 30, 2012

adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, exercise price, value and premiums received.

2d. Swaps

A table listing swaps follows each Fund’s Schedule of Investments (if applicable). Swaps are agreements that obligate two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. Swaps are used as a means to gain exposure to certain common stocks and/or to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the counterparty, the notional amount, the return paid and received by the Fund, termination date and the amount of unrealized appreciation or depreciation for total return swaps. The amount of unrealized appreciation or depreciation reflects the discounted value of the payments to be received from or paid to the counterparty for the last day of the reporting period.

3.  Statements of Assets and Liabilities

These statements are often referred to as the “balance sheets.” They list the assets and liabilities of the Funds on the last day of the reporting period.

The Funds’ assets are calculated by adding the value of the securities owned, the receivable for securities sold but not yet settled, the receivable for dividends declared but not yet received on stocks owned and the receivable for Fund shares sold to investors but not yet settled. The Funds’ liabilities include payables for securities purchased but not yet settled, Fund shares redeemed but not yet paid and expenses owed but not yet paid. Additionally, there may be other assets and liabilities such as unrealized gain or loss on forward currency contracts.

The section entitled “Net Assets Consist of” breaks down the components of the Funds’ net assets. Because the Funds must distribute substantially all earnings, you will notice that a significant portion of net assets is shareholder capital.

The last section of this statement reports the net asset value (“NAV”) per share on the last day of the reporting period. The NAV is calculated by dividing the Funds’ net assets (assets minus liabilities) by the number of shares outstanding.

4.  Statements of Operations

These statements detail the Funds’ income, expenses, gains and losses on securities and currency transactions, and appreciation or depreciation of current Fund holdings.

The first section in this statement, entitled “Investment Income,” reports the dividends earned from stocks and interest earned from interest-bearing securities in the Funds.

The next section reports the expenses incurred by the Funds, including the advisory fee paid to the investment adviser, transfer agent fees and expenses, and printing and postage for mailing statements, financial reports and prospectuses. Expense offsets and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The Funds will realize a gain (or loss) when they sell their position in a particular security. An unrealized gain (or loss) refers to the change in net appreciation or depreciation of the Funds during the reporting period. “Net Realized and Unrealized Gain/(Loss) on Investments” is affected both by changes in the market value of Fund holdings and by gains (or losses) realized during the reporting period.

5.  Statements of Changes in Net Assets

These statements report the increase or decrease in the Funds’ net assets during the reporting period. Changes in the Funds’ net assets are attributable to investment operations, dividends, distributions and capital share transactions. This is important to investors because it shows exactly what caused the Funds’ net asset size to change during the period.

The first section summarizes the information from the Statements of Operations regarding changes in net assets due to the Funds’ investment performance. The Funds’ net assets may also change as a result of dividend and capital gains distributions to investors. If investors receive their dividends in cash, money is taken out of the Funds to pay the distribution. If investors reinvest their dividends, the Funds’ net assets will not be affected. If you compare each Fund’s “Net Decrease from Dividends and Distributions” to the “Reinvested dividends and distributions,” you will notice that dividend distributions had little effect on each Fund’s net assets. This is because the majority of Janus investors reinvest their distributions.

The reinvestment of dividends is included under “Capital Share Transactions.” “Capital Shares” refers to the money investors contribute to the Funds through purchases or withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days or less by a shareholder. The Funds’ net

Financial Statements (unaudited) (continued)

assets will increase and decrease in value as investors purchase and redeem shares from the Funds.

6.  Financial Highlights

This schedule provides a per-share breakdown of the components that affect each Fund’s NAV for current and past reporting periods. Not only does this table provide you with total return, it also reports total distributions, asset size, expense ratios and portfolio turnover rate.

The first line in the table reflects the NAV per share at the beginning of the reporting period. The next line reports the net investment income per share, which comprises dividends and interest income earned on securities held by the Funds. Following is the total of gains/(losses), realized and unrealized. Dividends and distributions are then subtracted to arrive at the NAV per share at the end of the period. The next line reflects the average annual total return reported the last day of the period. The total return may include adjustments in accordance with generally accepted accounting principles. As a result, the total return may differ from the total return reflected for shareholder transactions.

Also included are the expense ratios, or the percentage of average net assets that were used to cover operating expenses during the period. Expense ratios vary across the Funds within the Trust for a number of reasons, including the differences in management fees, the frequency of dividend payments and the extent of foreign investments, which entail greater transaction costs.

The Funds’ expenses may be reduced through expense-reduction arrangements. These arrangements may include the use of balance credits or transfer agent fee offsets. The Statements of Operations reflect total expenses before any such offset, the amount of the offset and the net expenses. The expense ratios are listed in the Financial Highlights.

The ratio of net investment income/(loss) summarizes the income earned less expenses, divided by the average net assets of a Fund during the reporting period. Don’t confuse this ratio with a Fund’s yield. The net investment income ratio is not a true measure of a Fund’s yield because it doesn’t take into account the dividends distributed to the Fund’s investors.

The next figure is the portfolio turnover rate, which measures the buying and selling activity in a Fund. Portfolio turnover is affected by market conditions, changes in the asset size of a Fund, fluctuating volume of shareholder purchase and redemption orders, the nature of the Fund’s investments and the investment style and/or outlook of the portfolio manager. A 100% rate implies that an amount equal to the value of the entire portfolio was replaced once during the fiscal year; a 50% rate means that an amount equal to the value of half the portfolio is traded in a year; and a 200% rate means that an amount equal to the value of the entire portfolio is traded every six months.

Janus provides access to a wide range of investment disciplines.

Alternative

Janus alternative funds seek to deliver strong risk-adjusted returns over a full market cycle with lower correlation to equity markets than traditional investments.

Asset Allocation

Janus’ asset allocation funds utilize our fundamental, bottom-up research to balance risk over the long term. From fund options that meet investors’ risk tolerance and objectives to a method that incorporates non-traditional investment choices to seek non-correlated sources of risk and return, Janus’ asset allocation funds aim to allocate risk more effectively.

Fixed Income

Janus fixed income funds attempt to provide less risk relative to equities while seeking to deliver a competitive total return through high current income and appreciation. Janus money market funds seek capital preservation and liquidity with current income as a secondary objective.

Global & International

Janus global and international funds seek to leverage Janus’ research capabilities by taking advantage of inefficiencies in foreign markets, where accurate information and analytical insight are often at a premium.

Growth & Core

Janus growth funds focus on companies believed to be the leaders in their respective industries, with solid management teams, expanding market share, margins and efficiencies. Janus core funds seek investments in more stable and predictable companies. Our core funds look for a strategic combination of steady growth and, for certain funds, some degree of income.

Mathematical

Our mathematical funds seek to outperform their respective indices while maintaining a risk profile equal to or lower than the index itself. Managed by INTECH (a Janus subsidiary), these funds use a mathematical process in an attempt to build a more “efficient” portfolio than the index.

Value

Our value funds, managed by Perkins (a Janus subsidiary), seek to identify companies with favorable reward to risk characteristics by conducting rigorous downside analysis before determining upside potential.

A FASTER TRACK

Timing can be an important element in investing, but it’s unusual to be proved correct faster than you had expected. During the period we saw many of our 2012 theses come to fruition more quickly than we had anticipated. The world became more risk-tolerant, fueling a rally in equity and credit markets that was especially strong in the first quarter of 2012. In general, the period was positive for active managers with a focus on individual security selection.

Among the positives was that the European debt crisis, while not resolved, showed some progress toward resolution. The U.S. economic recovery continued, albeit at a slow pace, and China’s economy showed signs of heading toward a soft landing. As some of the macroeconomic noise subsided, investors were able to sustain a focus on corporate fundamentals and individual security selection for the first time in more than a year.

Economic headwinds remain, of course. Although the U.S. economy is not growing at its potential, we continue to expect gross domestic product to expand by 2% to 2.5% this year. Europe has greater challenges. Although the massive liquidity pushed into the system by the European Central Bank during the period reduced a significant amount of downside risk, the reality is sinking in that European growth is going to be slower for longer than many had expected. The need for additional stimulus and restructuring in some of the peripheral countries, such as Spain, is becoming increasingly apparent. Another question is whether China’s economy will avoid a hard landing. China is the biggest growth driver in Asia, and the global economy is very dependent on Asian growth right now.

Meanwhile, despite the improving economy, U.S. political dysfunction continues and likely will accelerate over the next few months as we head into the election season. The U.S. government likely will reach the debt ceiling again by the end of 2012, around the same time that the Bush tax cuts, extended unemployment benefits and the payroll tax holiday are scheduled to expire. A replay of the dysfunction we experienced last year in Washington will be coming back to a theater near you.

EQUITIES: BACK TO FUNDAMENTALS

One of the positives seen during the period was a reduction in the extraordinarily high equity correlations that we saw for much of 2011. That is positive for individual security selection and for our relatively concentrated, high-conviction portfolios. Increased investor risk tolerance and a renewed focus on fundamentals likely will create a faster track for companies with strong management teams and winning corporate strategies. These businesses are widening the gap between themselves and their less well-positioned rivals.

We do not believe at this point that equities are overvalued. U.S. companies have shown their ability to grow in a weak economic climate, and we are not seeing signs of that growth slowing. For many companies, margins have risen due to aggressive cost cutting and restructuring, along with worker productivity gains. Stronger revenue growth will be critical for companies to maintain or grow margins from here. For businesses that are fundamentally strong, this should not be more challenging today than it was in a tougher economic climate.

FIXED INCOME: RISK ASSETS TAKE FLIGHT

In the early months of this year, we watched credit markets, particularly high yield, accomplish in weeks a level of gains that we had assumed would take months. While still bullish, we viewed this as an opportunity to take profits in bonds that reached target valuations, as well as to reduce our exposure to higher-beta securities that performed well. (Beta is a measure of the volatility of a portfolio in comparison to a benchmark index. A beta less than one means the portfolio is less volatile than the index, while a beta greater than one indicates more volatility than the index.) We have re-examined credit in our portfolios, retaining investment-grade securities that we believe offer the best relative value and high-yield credits with the least downside risk, as we prepare for the next leg of the market.

The world remains significantly out of balance. The deleveraging process continues as individuals,

corporations, banks and ultimately governments realize that growth hinges on improving their financial positions. We believe that fundamentals still support corporate credit in the near term. Companies continue to improve liquidity profiles and balance sheets, retaining financial discipline despite an improving economy. The capital markets remain wide open to high-yield issuers, allowing for refinancing and terming out of debt maturities, a positive outcome of the current zero-interest-rate-policy environment. We continue to see what we believe are compelling valuations in sectors including financials and energy, and to believe success in fixed income is driven by individual security selection with a focus on risk-adjusted returns and preservation of capital.

Sincerely,

Jonathan Coleman

Useful Information About Your Fund Report (unaudited)

Market Perspectives and Management Commentaries

The Management Commentaries in this report include valuable insight from each of the Fund’s managers as well as statistical information to help you understand how your Fund’s performance and characteristics stack up against those of comparable indices.

If a Fund invests in foreign securities, this report may include information about country exposure. Country exposure is based primarily on the country of domicile. However, the Funds’ managers may allocate a company to a country based on other factors such as location of the company’s principal office, the location of the principal trading market for the company’s securities, or the country where a majority of the company’s revenues are derived.

Please keep in mind that the opinions expressed by the Chief Investment Officer(s) (“CIO”) in the Market Perspectives and by the Funds’ managers in the Management Commentaries are just that: opinions. They are a reflection of the CIOs’ and managers’ best judgment at the time this report was compiled, which was March 31, 2012. As the investing environment changes, so could their opinions. These views are unique to each CIO and manager and aren’t necessarily shared by fellow employees or by Janus in general.

Fund Expenses

We believe it’s important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

The following is important information regarding each Fund’s Expense Example, which appears in each Fund’s Management Commentary within this Semiannual Report. Please refer to this information when reviewing the Expense Example for each Fund.

Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments (applicable to Class A Shares only); redemption fees, as applicable (and any related exchange fees); and (2) ongoing costs, including management fees; distribution and shareholder servicing (12b-1) fees (applicable to Class A Shares, Class C Shares, Class R Shares and Class S Shares only); administrative services fees payable pursuant to the Transfer Agency Agreement; and other Fund expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based upon an investment of $1,000 invested at the beginning of the period and held for the six-month period from October 1, 2011 to March 31, 2012.

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

The second line of the table in each example provides information about hypothetical account values and hypothetical expenses based upon each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Janus Capital Management LLC (“Janus Capital”) has contractually agreed to waive certain Funds’ total annual fund operating expenses, excluding any performance adjustments to management fees, if applicable, class-specific distribution and shareholder servicing (12b-1) fees (applicable to Class A Shares, Class C Shares, Class R Shares and Class S Shares only), administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, to certain limits until at least February 1, 2013. Expenses in the examples reflect application of these waivers. Had the waivers not been in effect, your expenses would have been higher. More information regarding the waivers is available in the Funds’ prospectuses.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as redemption fees (as applicable) and any related exchange fees. These fees are fully described in the prospectus. Therefore, the second line of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Fund Snapshot
Given the dynamic nature of Asian markets, equity prices may not at times fully reflect business fundamentals. As such, fundamental research is the foundation of our Asia investment strategy. We believe that GARP (growth at a reasonable price) is the most suitable style for the fastest growing region in the world. Through fundamental research and analysis, GARP aims to take advantage of market mispricing to achieve excess returns on a sustainable basis and in a risk-controlled manner.

Performance

Janus Asia Equity Fund’s Class I Shares returned 22.75% for the six-month period ended March 31, 2012. The Fund’s benchmark, the MSCI All Country Asia ex-Japan Index, returned 17.45%.

Market Overview

Asian equities recorded strong gains following a deep sell-off in the third quarter of 2011. Global equities, in general, rebounded strongly in October on hopes European leaders were nearing answers to its debt problems, but concerns re-emerged in November and December as the potential for a recession in Europe rose and muted the period’s overall returns. Corporate earnings were strong, but the market remained focused on the macro-economic environment. In India, political infighting delayed badly needed infrastructure projects. High interest rates and inflation as well as battles over corruption weighed on the country’s stock market. Meanwhile, China announced the reserve requirement ratio for its banks would be lowered in an effort to boost liquidity after having raised the ratio six times during 2011.

Over the last half of the period, stocks rallied significantly thanks largely to receding risks in Europe and China. The European Central Bank’s liquidity program (Long Term Refinancing Operations or LTRO) provided a significant buffer to the European debt markets, which in turn encouraged investors to invest more in equities. In China, concerns over a hard landing, a reversal in its investment cycle and inflation pressures also eased. Finally, we think investors took advantage of what we considered cheap valuations in Asia. In 2011, Asian companies grew earnings 5% on average (with expectation of 10% growth in 2012) while stock prices fell 17%, resulting in an approximate 25% decline in the region’s prices-to-earnings (P/E) multiple (a valuation ratio of a company’s current share price compared to its per-share earnings). Once economic conditions began normalizing, investors also normalized their decision-making.

Performance Overview

On a country basis, our holdings and overweight in China were easily the largest relative contributors followed by our holdings in Taiwan and Hong Kong. Detractors included our holdings in South Korea and our holdings and underweight in Thailand. Among sectors, our holdings in consumer discretionary and materials were the largest relative contributors followed by our holdings in information technology and industrials. Detractors included our consumer staples holdings, which were mostly offset by our favorable underweight exposure to the sector. Our health care holdings also weighed on relative performance.

Individually, Samsung Electronics’ shares rallied during the period. We consider Samsung, our largest holding, to be the largest and most competitive electronics company in the world. Samsung’s DMC (Digital, Media and Communication) business has been particularly strong due to significant handset shipments and TV sales. We feel its leadership in handsets is likely to continue with innovative product launches (such as the Galaxy Note). We also anticipate profitability improvement in its DRAM memory chip business due to cutbacks by other money-losing DRAM makers.

China National Building Material, the second largest cement producer in China, also rose significantly. The stock benefited from reduced concerns that China would face a hard landing (a recession as a result of government attempts to slow inflation). We significantly trimmed our position but continue to see upside in the company’s shares relative to the historical high returns on equity it has generated. We think the company continues to build its market share by acquiring smaller cement companies to improve energy consumption efficiency. We also appreciate its potential to benefit from China’s ongoing strong fixed asset investment growth.

In addition, Great Wall Motor Co. was a key contributor. The stock rose significantly during the period after the

Janus Global & International Funds | 5

Janus Asia Equity Fund (unaudited)

company reported strong year-over-year sales that outpaced peers. We added to our position in China’s largest SUV maker. Through its exposure to faster growing regions, focus on SUVs and higher product quality, this Chinese automaker should grow faster than the market, in our view. Since Great Wall Motor was valued at a discount to peers, we added to our position.

Among detractors, EVA Precision Industrial declined modestly after we purchased it. This Chinese manufacturer of metal stamping and plastic injection molds suffered from margin contraction in 2011, when its main Japanese customers pressured it for price cuts following the earthquake and tsunami that hit Japan in March of 2011. We think EVA will achieve an earnings recovery in 2012 driven by strong orders and an acquisition.

Leading Indian energy conglomerate Reliance Industries also weighed on performance. Reliance was negatively impacted by a slowdown in government project approvals due to an ongoing crackdown on corruption within the country. Although the company’s refining margins continue to be under pressure, its petrochemical business remains solid. Also, there are signs that the Indian government may approve changes in its natural gas pricing policies.

Finally, India’s Yes Bank suffered from weakness in the Indian market early in the period. The mid-size Indian bank has a quality management team and good growth strategy, in our view. We feel Yes Bank will benefit from interest liberalization in its current accounts and saving accounts (CASA) and implementation of management’s growth strategy.

Derivatives

During the period, we used currency derivatives to hedge existing currency exposures and swaps to access markets in which we were not trading locally either due to our risk policies or an inability to trade locally. We also executed sales and purchases of puts and calls to hedge existing equity exposures and sold puts on non-existing positions to hedge other similar securities. In aggregate, these positions contributed to relative performance. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Outlook and Positioning

We continue to see more upside potential for Asian equities. The region’s P/E multiple traded at 12x 2012 earnings as of period end, which is lower than its 20-year average of 15.2x (based on MSCI data). We think gains are most likely to occur during the first half of the year, so we continue to overweight cyclical sectors such as consumer discretionary and industrials and look for companies that have lagged in stock performance but continue to demonstrate good growth characteristics. We also have a more modest overweight in the materials sector based on Chinese reforms that could benefit the country’s coal companies. If the markets continue to remain strong in the second quarter, we hope to capture gains and position sectors to a more neutral position relative to our index.

On a country level, we remained overweight in China and Hong Kong, while we were underweight in India and Taiwan. We think China is on pace to achieve a soft economic landing, in terms of both growth and inflation control, after a period of monetary tightening. The Chinese Government lowered its target growth rate from 8% to 7.5%, but that was unsurprising to us. China normally will target a rate below the rate actually achieved. We think the first quarter will be the country’s slowest in terms of growth and are expecting approximately 8.5% growth for 2012, as compared to 9.2% growth in 2011. Our Hong Kong exposure is also largely tied to continued growth in China.

We continue to see a number of fundamental challenges in India led by its importation of oil and raw materials and its expanding budget deficit. High oil prices will likely lead to more deficits for India. The Indian equity market is also highly influenced by foreign investors, which causes it to be more volatile than other Asian markets. Within India, our holdings have cyclical exposure and therefore can be volatile as well. To help offset our holdings’ volatility, we underweighted the country’s exposure. In Taiwan, we were underweight in the country’s chemical and steel industries at period end since we view those as lacking in global competitiveness.

Thank you for your investment in Janus Asia Equity Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), real estate investment trusts (“REITs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in REITs which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Sovereign debt securities are subject to the additional risk that, under some political, diplomatic, social or economic circumstances, some developing countries that issue lower quality debt securities may be unable or unwilling to make principal or interest payments as they come due.

Due to certain investment strategies, the Fund may have an increased position in cash.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

The Fund’s performance for very short time periods may not be indicative of future performance.

Lipper does not rank this Fund as it is less than one year old.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore, its performance does not reflect the expenses associated with the active management of an actual portfolio.

Janus Emerging Markets Fund (unaudited)

Fund Snapshot
We believe company fundamentals and managements’ ability to create value drive share prices over the long-term in emerging markets. We seek to take advantage of opportunities created when investors primarily focus on near-term sentiment and macroeconomic risk factors while ignoring fundamental company research. We buy companies trading well below our conservative estimate of their long-term value and favor quality companies with what we believe are sustainable competitive advantages and high or improving returns on capital.

Performance

Janus Emerging Markets Fund’s Class I Shares returned 20.07% for the six-month period ended March 31, 2012. The Fund’s benchmark, the MSCI Emerging Markets Index, returned 19.12%.

Market Overview

Emerging markets generated strong performance during the period thanks to a reduction in global fears and consequently a rise in risk appetites among investors. The approval of another bailout of Greece and the successful conclusion of a Greek debt restructuring along with general lessening of worries over European sovereign debt helped sentiment. We’ve also seen inflation in many countries, such as Brazil and China, begin to decline along with slower GDP growth. The slower economic growth is healthy in that it has allowed inflation to come within a more moderate range. Finally, we think the strong performance by emerging markets reflects there were great businesses mispriced relative to their long-term return and growth profiles.

Performance Overview

Among sectors, our holdings in energy were the largest relative contributors followed by our holdings in consumer staples and telecommunication services. Detractors included our holdings in industrials, financials and materials.

Within energy and for the Fund overall, Karoon Gas Australia and Cobalt International Energy were among the largest individual contributors. Higher crude oil prices helped the entire sector, but these companies also had positive developments. Australia-based Karoon Gas benefited from raised investor expectations for its Brazilian offshore development sites, and Cobalt, a U.S. company, reported a significant discovery in one of its West African offshore wells.

One of the Fund’s largest holdings, Samsung Electronics, also generated strong gains during the period. Samsung has dramatically grown market share in smart phones and continues to turn out some of the best products in the world. Additionally, its memory chip business (the largest in the world) should benefit from increased spending in consumer electronics and enterprise hardware.

Among detractors, India’s Adani Enterprises declined due to relative weakness in the Indian equity market and lack of progress in government approvals for some of its projects. Our overweight and holdings in India were the largest relative detractors on a country basis. We continue to like the Adani’s long-term prospects. Using an integrated approach involving coal mining, coal logistics and power generation to power transmission, Adani is uniquely positioned, in our view, to better mine domestic coal and transport it from the Eastern India coal belt to the Western India power plants via its rail and port facilities.

Jain Irrigation Systems, another Indian company, also weighed on performance. Jain has a market-leading position in India’s micro-irrigation systems, which are subsidized by the government. We feel these irrigation systems are the fastest way to improve yields and represent a large market opportunity, given the unpredictability of India’s monsoon season and that many farms don’t have simple water catchment systems. The company has been delayed in rolling out its financing business, which we think will reduce the company’s working capital costs.

First Solar, a maker of solar modules and provider of solar power systems, declined as part of general weakness in its industry. We continue to like the company’s outlook and added to our position. The designer and manufacturer of solar modules using a thin film semiconductor technology is the low-cost manufacturer in its industry, in our view. We think the company is continuing to lower the cost of kilowatt per hour, and it is diversifying its end markets.

Derivatives

During the period, we used currency derivatives to hedge existing currency exposures and swaps to access markets in which we were not trading locally either due to our risk policies or an inability to trade locally. We also executed sales and purchases of puts and calls to hedge existing equity exposures and sold puts on non-existing positions to hedge other similar securities. In aggregate, these positions contributed to relative performance. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Conclusion

While slower growth in China has concerned some investors, we take a multi-year view that still points to considerable growth ahead. China’s steel consumption, relative to Japan’s peak level during its development, can still grow 40% to 50% by our estimation. Currently, approximately 52% of its population lives in cities; we think that will increase to 70% to 80% a few years. In terms of square footage housing construction per year per person, China is still far less than the U.S. at its peak.

We also see attractive opportunities in frontier markets such as United Arab Emirates with its growing banking industry, offshore West Africa’s promising oil fields and Mongolia’s potential world-class copper mine.

In India, the pace of governmental reforms has been slower than we had anticipated. The government has started to show signs of movement in terms of plans to raise the price of natural gas and allowing the importation of coal to avoid rolling electrical blackouts. The opportunities in India are significant, but we need to see implementation of structural reforms to become more optimistic.

In general, we think emerging markets will continue to be the growth driver for global markets. They have very large populations that will continue to urbanize and grow their middle classes. As per capita incomes in these countries rise, consumer spending will grow as well. They will also benefit from their incredibly rich resource bases. We remain very optimistic about these markets and are finding companies that can thrive in a high-growth environment and do well in a low-growth environment.

Thank you for your investment in Janus Emerging Markets Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), real estate investment trusts (“REITs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Janus Emerging Markets Fund held approximately 12.2% of its total investments in Brazilian securities as of March 31, 2012 and the Fund may have experienced significant gains or losses due, in part, to its investments in Brazil. While holdings are subject to change without notice, the Fund’s returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in Brazil.

The Fund invests in REITs which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class I Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore, its performance does not reflect the expenses associated with the active management of an actual portfolio.

Expenses include effect of contractual waivers by Janus Capital.

*

Pursuant to a contractual agreement, Janus Capital waived certain fees and expenses during the six-month period for Class A Shares, Class C Shares, Class D Shares, Class S Shares and Class T Shares. Without these waivers, the expenses paid during the period would have been $9.29 for Class A Shares, $13.67 for Class C Shares, $8.91 for Class D Shares, $10.28 for Class S Shares and $9.08 for Class T Shares.

Janus Global Life Sciences Fund (unaudited)

Fund Snapshot
We take a global approach to identify high quality or improving businesses in the life sciences sector trading at a discount to our estimate of intrinsic value. We believe the rapidly growing global health care sector offers fertile opportunities for differentiated research. We believe what sets us apart is the quality of our team, the depth of our research and our commitment to delivering superior long-term results for our clients.

Andy Acker
portfolio manager

Performance Overview

Janus Global Life Sciences Fund’s Class T Shares returned 25.73% over the six-month period ended March 31, 2012, roughly in line with the Fund’s primary benchmark, the S&P 500 Index, which returned 25.89%. However, this was significantly ahead of the MSCI World Health Care Index, the Fund’s secondary benchmark, which returned 16.10% during the period.

Sector Overview

We saw a reversal of trends from late 2011 when health care’s historically defensive characteristics led cautious investors into large cap pharmaceutical stocks. With improving economic conditions early in 2012, investors moved out of large pharmaceuticals and into other areas of health care that had previously underperformed, namely medical devices, life science tools and biotechnology. The move into biotechnology was aided by increased acquisition activity, and some new drug launches that exceeded expectations, supporting our view that drugs that offer a clear improvement over current therapies can still be rapidly adopted.

Investment Strategy

The Fund seeks to uncover opportunities that span the life sciences spectrum, including stocks in the biotechnology, pharmaceutical, health care service and medical technology arenas. Our bottom-up fundamental approach utilizes extensive proprietary research in an effort to discover the best investment ideas across the globe. Our focus remains on companies that are addressing high unmet medical needs and those that we believe will benefit from making the health care system more efficient. We also believe that management teams that make better capital allocation decisions will be rewarded.

Fund Composition

The Fund includes companies that can be categorized into three conceptual groups: core growth, emerging growth and opportunistic investments. In general, about half of the portfolio is invested in core growth holdings (companies with dominant franchises that generate strong, consistent free cash flow). Emerging growth companies (those with new products that we believe can drive earnings acceleration) represent 20-30% of the portfolio. The remaining weighting consists of opportunistic investments, exemplified by companies suffering from what we feel are short-term issues that should resolve over time.

Detractors from Performance

Biotechnology holding Targacept was the largest detractor from performance during the period. Despite highly promising proof of concept data for a novel treatment for refractory depression, late stage clinical trials failed to confirm a therapeutic benefit, leading to a significant decline in the shares. While our Value at Risk approach (see below) prompted us to reduce our position size in front of this binary event, we nevertheless exited the position at a loss.

Mitsubishi Tanabe Pharma suffered from European regulators’ concerns over potential cardiovascular safety issues involving one of the Japanese company’s main products, Gilenya, an oral multiple sclerosis drug. Competition has also increased for the company’s other main asset, a hepatitis C drug, Telaprevir. We reduced our position, but we continue to think the company has solid growth prospects.

Additionally, Chelsea Therapeutics declined significantly due to a delay in obtaining Food and Drug Administration approval for its new drug to treat some of the symptoms of Parkinson’s disease. Although the risk has increased, we continue to believe the drug has a chance for approval, based on additional studies the company currently has underway.

Contributors to Performance

Regeneron was easily the largest contributor with a significant return during the period. The stock was driven

(unaudited)

by a strong launch for Eylea, a next generation drug for wet age-related macular degeneration (AMD), the leading cause of blindness for the elderly. We believe Eylea has potency, cost and convenience advantages over the current standard of care, which has led to a better than expected uptake in the market. Beyond Eylea, we feel Regeneron has a strong technology platform (backed by a lucrative collaboration with Sanofi), and an undervalued pipeline of novel antibody drug candidates, including a potential leading therapy in a new class of cholesterol lowering agents.

Pharmacy benefit manager Express Scripts was another key contributor. It became increasingly apparent that Express Scripts’ proposed acquisition of fellow PBM, Medco Health Solutions, would be approved by regulators, which occurred on April 2. We think the acquisition could generate significant cost savings and would make Express Scripts the dominant provider of PBM services. We believe PBMs are well positioned to benefit from the wave of patent expirations of branded drugs that is currently underway, and from the rapid growth of specialty pharmaceuticals in the coming years.

Amylin Pharmaceuticals saw its stock rise significantly during the period, driven by three positive events. First, the company received the long awaited approval for its diabetes drug Bydureon after several years of regulatory delays. Second, early signs of physician interest and commercial uptake have been encouraging. Finally, press reports indicated that a large pharmaceutical company had made an unsolicited takeout offer for Amylin, sparking speculation about a potential sale. We trimmed our position on the stock’s gains, but continued to hold due to the large market for diabetes treatments and the promise of Bydureon’s more convenient formulation (once a week vs. daily injections). We believe these characteristics could make Amylin an attractive acquisition candidate.

Risk Management

The Fund continues with its “value at risk” approach as part of a comprehensive risk management framework. This approach focuses our attention on downside risks, especially those arising from binary events (such as clinical trial announcements or regulatory decisions) that can lead to significant share price volatility. In practice, this means we limit the position size of any one holding so that, in a worst-case scenario, the estimated adverse impact from a particular event should not exceed 1% of the Fund’s performance. Please see the Derivative Instruments section in the “Notes to Financial Statements” for derivatives used by the Fund.

Looking Ahead

We remain cautious on many large pharmaceutical companies given the significant upcoming patent expirations and lack of sufficient drug pipelines to offset these losses. We also continue to expect a slower pace for many new drug launches, due to pressure from health insurance companies to reduce cost by requiring not just safety and efficacy for many new therapies, but also demonstrated economic value. We think this environment continues to favor innovative companies that address high unmet medical needs. We believe recent acquisitions at significant premiums in the hepatitis-C market underscore this trend.

We have lowered our pharmaceutical exposure from last year by taking profits in GlaxoSmithKline and Bristol-Myers Squibb, and investing the proceeds in companies that we believe have more underappreciated growth potential. We continue to find many attractive opportunities throughout the sector, including stocks of generic drug companies, biotechnology firms, PBMs and drug distributors.

Thank you for your continued investment in Janus Global Life Sciences Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), derivatives, and short sales. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund invests in certain industry groups, which may react similarly to market developments (resulting in greater price volatility), and may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of one or more other share classes of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations and waivers. If each share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities.

Janus Global Research Fund (unaudited)

Fund Snapshot
We believe a deep, independent research process and high-conviction investing can deliver exceptional results by exploiting a market’s tendency to focus on the short term. We believe a team-led research portfolio should control risk without diluting the strengths of a firm’s research effort.
Team-Based Approach
Led by Jim Goff,
Director of Research

Performance

Janus Global Research Fund’s Class T Shares returned 24.73% over the six-month period ended March 31, 2012. The Fund’s primary benchmark, the MSCI World Growth Index, returned 21.75%, and its secondary benchmark, the MSCI All Country World Index, returned 19.91% during the period.

Economic Overview

Global equity markets benefited from easing concerns over the European sovereign debt crisis, particularly a Greek default, and continued optimism from improving U.S. economic data. The combination of European Central Bank activities, led by its liquidity program (Long-Term Refinancing Operations or LTRO), a successful restructuring of Greek debt and stability in the U.S. housing market helped increase investors’ willingness to take risk and boosted corporate activity. Other positives included the Bank of Japan’s plans to target inflation and weaken its currency to stimulate its export-led economy. Signs that the Bank of China would further loosen bank reserve requirements to encourage more lending and the Brazilian central bank’s decision to lower interest rates also aided sentiment. The world’s major central banks have been able to ease monetary policy and stimulate their economies since inflation remains under control.

Contributors to Performance

Our holdings in consumer, financials and health care were the largest contributors to relative performance. On a country basis, our holdings in the U.S., Japan and the U.K. were the largest contributors.

Individually, Apple was the largest contributor during the period. The computer and mobile device maker benefited from a strong earnings report, driven by significant iPhone and iPad sales. Apple also initiated its first dividend and share repurchase program during the period. The company has been the beneficiary of incremental sales opportunities over the past few years from new geographies, such as China, phone service carriers and products, such as the iPad. We think it continues to have strong opportunities as its ecosystem grows; its products reach new countries; and lower price points draw new customers.

Chemical maker LyondellBasell’s shares also rose. Ethane, a raw material used in the production of ethylene, dropped the most in five months, improving profitability for the company. The large chemical producer has a cost advantage since the primary input to its production process is natural gas, a commodity that has experienced considerable price pressure due to excess supply. We also feel the company’s management team is return-on-capital driven and disciplined on investing in its business.

Fastenal was another key contributor; the stock benefited from a series of strong earnings reports. We like the industrial and construction supplier’s business model, management team and its growth profile going forward as it continues to gain market share.

Detractors from Performance

Despite LyondellBasell and Fastenal’s performances, our industrial holdings detracted from relative performance due largely to our holdings in Adani Enterprises, which declined due to relative weakness in the Indian equity market and lack of progress in government approvals for some of its projects. Our holdings and overweight in India were the largest relative detractors on a country basis. We continue to like the Adani’s long-term prospects. Using an integrated approach involving coal mining, coal logistics and power generation to power transmission, Adani is uniquely positioned, in our view, to better mine domestic coal and transport it from the Eastern India coal belt to the Western India power plants via its rail and port facilities.

Jain Irrigation Systems, another Indian company, also weighed on performance. Jain has a market-leading position in India’s micro-irrigation systems, which are subsidized by the government. We feel these irrigation systems are the fastest way to improve yields and represent a large market opportunity, given the unpredictability of India’s monsoon season and that many farms don’t have simple water catchment systems. The company has been delayed in rolling out its financing

business, which we think will reduce the company’s working capital costs.

Finally, Brazilian homebuilder PDG Realty declined after we purchased it during the period. The industry was weak late in the period due to the Brazilian interest rate curve moving higher following a release of the central bank’s minutes. We consider this company to have one of the best management teams in the industry and one that has historically created value for its shareholders. With a fast-growing platform that is increasingly well diversified by geography and by housing sector, PDG is attractive.

Conclusion

The global economic environment is improving, although not necessarily without pause. We think the generally positive trends in Europe and China will help the U.S. market. The Fund does not rely on a fast-growing economy as much as a return to normal levels of risk tolerance, correlations and volatility. When these measures align, it favors the stock picking opportunities available in the Fund. So far this year, stocks generally considered defensive have underperformed the rest of the market and we view this trend as a sign the market is returning to a healthy risk appetite. We are favoring companies with strong balance sheets and competitive positions where we think they will be able to withstand most economic situations.

Our sector teams see positive trends and opportunities. In financials, sentiment has improved as the markets reflect lower odds of a systematic banking crisis. We are seeing modest improvements in U.S. banks, including commercial and industrial loans, and credit card and auto lending. In the consumer sector, high-quality department stores that have a technological advantage are attractive to us; we also like consumer products companies with good exposure to emerging markets. Our health care team is investing in companies with breakthrough drugs that drive value creation, regardless of how health care reform plays out. The industrials team, for its part, prefers areas that have reduced capacity and could regain pricing power such as autos, airlines and general industries.

Thank you for your investment in Janus Global Research Fund.

Returns quoted are past performance and do not guarantee future results; current performance may be lower or higher. Investment returns and principal value will vary; there may be a gain or loss when shares are sold.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

See important disclosures on the next page.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class A Shares, Class C Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of one or more other share classes of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations and waivers. If each share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares, reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

February 28, 2005 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

Janus Global Select Fund (unaudited)

Fund Snapshot
We believe that investing in companies that are creating value by executing on a strategy to sustain or improve their economic profit margin but trading below intrinsic value, will allow us to outperform the index over time. We take a concentrated, opportunistic approach, seeking the most attractive investment opportunities, regardless of market capitalization or geography.

John Eisinger
portfolio manager

Performance Overview

For the six-month period ended March 31, 2012, Janus Global Select Fund’s Class T Shares returned 26.00% versus a return of 19.91% for the Fund’s primary benchmark, the MSCI All Country World Index.

Investment Environment

The market’s strong performance was driven by improving economic fundamentals in the United States, along with a reduction in the tail risk associated with the European banking system thanks to the introduction of the European Central Bank’s liquidity operations (Long Term Refinancing Operations (or LTRO)). The combination of these two factors drove down stock correlations from near all-time high levels at the end of 2011, which enabled individual stocks to express their true fundamentals and be revalued accordingly.

Performance Discussion

The Fund’s performance was driven by stock selection. In the past, we have written about the likelihood that this Fund’s returns will be lumpy, driven more by individual stock selection and less by the overall direction of the market. This is due to the concentrated nature of the portfolio (fewer stocks than the average portfolio) and therefore the larger impact that any one stock can have in a given period. Cobalt International Energy, Inc., for example, increased significantly during the period and contributed 8.09% to results. Cobalt was such a large contributor to performance because we increased its position size as it fell over 60% during the “risk-off” mentality that dominated in the fall of 2011, even though there was no change to the company’s fundamentals. While this type of decline is painful in the short-term from a returns point of view, it is where true money can be made for the long-term.

As a general principal, we try to use market volatility to our advantage, buying stocks that are in free fall when we have strong research-driven opinions on their true value. We find ourselves in this situation again, this time with Ivanhoe Mines, Ltd. The stock is down around 50% from its 2011 highs. We have added to our position, however, as our estimate of the value of the business has not fallen even though the stock price has declined. To us, the stock is even more attractive now.

Simply put, we look for the most attractive stocks based on our differentiated, research-driven opinion on what the business is worth as compared to what it is trading at in the market. The key metric we look at is return on invested capital (ROIC) and the ability and duration of a business to generate ROIC above its cost of capital. Breaking down ROIC that means we look for situations in which future growth (net operating profit after tax) is not being correctly priced by the market (or invested capital could be mispriced in the case of a restructuring, for example.). The valuation we reference is enterprise value/invested capital, as there is a proven relationship between the economic profits a company generates and the intrinsic value of the business. We do not look at multiples (Price/Earnings, Price/Sales etc.) because there is no relationship between a multiple and the value of the business.

Derivatives, primarily options, are used in the portfolio to generate income (through selling calls and selling puts), to have exposure to a position without owning it (generally selling a put to buy a call – often referred to as stock replacement), and periodically to hedge market risk (generally by buying puts in market indices, such as the S&P 500). The purpose of the option strategy is an attempt to generate income and reduce the risk in the portfolio. During the period, this strategy detracted from relative results. Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Contributors to Performance

Cobalt International Energy, Inc.

As mentioned above, Cobalt is an independent, oil-focused exploration and production company with

Janus Global & International Funds | 45

Janus Global Select Fund (unaudited)

substantial prospects offshore West Africa and in the Gulf of Mexico. We believe the stock is materially undervalued relative to the potential oil reserves it holds.

Morgan Stanley

We believe that Morgan Stanley’s returns should steadily improve, driven by organic growth and share gains in its higher return businesses (wealth management, equities, investment banking), expense reductions, and its expected acquisition of Citi’s stake in their wealth management joint venture. Higher returns should, in turn, drive significantly higher valuations versus current meaningful discount to tangible book, and further upside could also be realized if capital market conditions improve.

Isuzu Motors, Ltd.

Isuzu has a very strong position in mid and light-duty trucks in emerging markets (Southeast Asia and Middle East in particular), where demand is growing rapidly. The company also has a significant amount of spare capacity in Japan as the truck market there has shrunk. During the global financial crisis, Isuzu cut costs and lowered its breakeven point. As a result, incremental margins are very high as capacity utilization ramps up. This should drive rapid earnings growth and increasing returns on capital.

Detractors from Performance

EVA Precision Industrial Holdings, Ltd.

Stock performance was weak, driven by growing concerns of margin compression. However, we believe that EVA Precision is in the sweet spot of competitive positioning as the low-cost producer of office automation precision components, while also possessing the technical superiority, complexity and reputation for quality that other Chinese manufacturers cannot replicate. Longer term, we are confident in the company’s ability to capture more orders and gain market share not only in office automation, but the long runway of growth in the Chinese auto and home appliance market.

NRG Energy, Inc.

The company has been executing on its plan to slowly increase returns on capital and to restructure its balance sheet. However, the stock is susceptible in the short-term to changes in natural gas prices, which have continued to decline.

Vertex Pharmaceuticals, Inc.

The specialty pharmaceutical company announced excellent results on its latest quarterly conference call, but investors have started to worry about the duration for which the company’s hepatitis C drug will remain free of competition. These worries overwhelmed the positive fundamental data, causing the pullback in the stock. We sold the stock to reinvest the proceeds into what we consider to be better risk reward.

Outlook

The U.S. is in the midst of an economic recovery and we are seeing many indicators that make us moderately bullish. Company surveys by the research group ISI, measuring sales versus expectations, are at 5-year highs. Unemployment claims are at a post-recession low. The University of Michigan jobs survey increased to a record high in the first quarter (this survey has a high correlation with payroll employment). Real consumer spending is well above its 2007 peak. Corporate profits in the fourth quarter increased 7% year over year, according to ISI, with dividends up 15%, and payout ratios are near record lows (suggesting dividend growth should remain robust). ISI’s homebuilder survey broke above 50 and its house price survey made an upside breakout. ISI’s economic diffusion index, which incorporates all the U.S. economic and market data the company tracks, also made a new high. Other encouraging data include increases in asking prices of homes for sale, increases in building permits, increases in traffic of prospective home buyers and a stock market that is reasonably valued at about 13 times earnings.

However, the world is not without risk, which remains centered in Europe. Although the introduction of the LTRO did reduce tail risks, the core problems of over-indebtedness, austerity induced negative growth in the periphery and rising social risks remain. Peripheral bond spreads have started to widen again, which reflects the worse-than-expected growth and unrealistic deficit targets. Social and political issues are also contributing to the uncertainty with Irish referendums, elections in France, and mid 20% unemployment rates in Spain. We remain underweight Europe in the portfolio.

Offsetting this is continued steady growth in Asia and Latin America. We see falling growth rates and inflation in many of these geographies, which should help policy makers move to more accommodative stances that can help equity markets. We continue to see strong long-term growth and wealth creation in many of these markets and remain overweight in the portfolio.

Net of it all, we expect an improving U.S. economy and continued growth in emerging markets to offset the weakness emanating from Europe. We think it is prudent to expect continued bouts of volatility in the market, which we seek to take advantage of by buying great stocks for the long-term.

Thank you for investing in Janus Global Select Fund.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund’s performance may be affected by risks that include those associated with nondiversification, investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), derivatives, and short sales. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the indices. The indices are unmanaged and are not available for direct investment; therefore, their performance does not reflect the expenses associated with the active management of an actual portfolio.

Expenses are equal to the annualized expense ratio of 1.17% for Class A Shares, 1.86% for Class C Shares, 0.88% for Class D Shares, 0.90% for Class I Shares, 1.47% for Class R Shares, 0.27% for Class S Shares and 0.96% for Class T Shares multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Expenses include effect of contractual waivers by Janus Capital.

A non-recurring expense adjustment impacted the ratio for Class S Shares. The expenses paid during the period would have been $6.79 for Class S Shares without the non-recurring expense adjustment.

Janus Global Technology Fund (unaudited)

Fund Snapshot
We seek to identify strong technology-related businesses with sustainable competitive advantages and improving returns on capital. We believe what sets us apart is the depth of our research, our investment conviction, and our commitment to delivering superior long-term results for our clients.

Brad Slingerlend
portfolio manager

Performance

Janus Global Technology Fund’s Class T Shares returned 25.58% over the six-month period ended March 31, 2012. The Fund’s primary benchmark, the S&P 500 Index, returned 25.89%, and its secondary benchmark, the MSCI World Information Technology Index, returned 28.20% during the period.

Market Environment

Technology stocks helped lead global indices higher during the period after a weak relative performance during calendar year 2011. The rebound was due in part to supply chain semiconductor stocks bouncing off a cyclical low and investors taking advantage of low valuations in large cap technology companies. Improvement in the U.S. economy helped consumer discretionary stocks, which positively impacted consumer electronics like smartphones and tablet computers. Enterprise IT spending was moderately slower due to Europe’s sovereign debt crisis, weakness in financial services broadly, and modest softening in U.S. federal government spending. However, companies focused on big data, server virtualization, storage and cloud computing did not see a slowdown. There was a downturn in hard-disk storage production in the fourth quarter of 2012 due to floods in Thailand, where many key hard-drive components are made. However, the hard-drive impact had largely eased during the first quarter of 2012.

Portfolio Manager Comments

Although the Fund returned solid absolute performance, we were disappointed with the relative performance in the period. We focus our time and effort positioning the portfolio to outperform over the long term, and this past year did not go our way. Compared to the MSCI World Information Technology Index we owned more cyclical companies which underperformed in an uncertain global economic environment, and fewer services companies which outperformed. Our focus on deriving insights from in depth fundamental research remains the same. We continue to find attractive companies to own in the technology sector with strong long-term prospects. Two of our key themes are 1) the rise of the smart phone globally, and 2) increasing use of data analytics – I would like to spend some time exploring these topics here.

Will Homo economicus prove to be real after all? Since Adam Smith begat modern economic theory we have always relied on the flawed idea that the human species is rational and self-interested with access to perfect information. However, in modern times, these flaws in traditional economic theory have created wide ranging global economic challenges. But, is this now changing because of two important trends in technology – smart phones and data analytics?

In theory, the price of ice cream should be the same at your nearby grocery store and your nearby super center, but this is not true in practice. Rational consumers should seek out the best price, but often irrational notions factor into purchase decisions – convenience, lack of information, etc. But what if you did have access to perfect, real-time information?

Say you are in the market for a new LCD TV: using eBay’s Red Laser app you can scan barcodes as you walk through Best Buy and find the lowest price either online or at other physical stores near you.

Say you want to live healthier: new healthcare smartphone apps allow you to very easily track your food consumption and exercise, or even monitor key aspects of your body. Will this access to information cause people to eat healthier, exercise more and generally be happier? In a rational world it certainly would change behavior, with large implications to insurers and drug companies.

Say you want to know where to buy the cheapest basket of groceries nearest to you: now, with shopping list apps you can see where your basket of items is the cheapest.

There is a behavioral revolution taking place with smartphones. Access to the world’s information in your pocket with easy and inexpensive apps to provide you data should allow Homo economicus, the rational

consumer, to finally behave according to “theory.” Many economic theories that are intuitively logical, but have been thrown out, may turn out to be quite true in the midst of this revolution.

So what does this have to do with investing in tech stocks? Good question.

Platforms: New platforms are key to enabling this transformative trend in data. Companies like Amazon.com, with their cloud computing platform Amazon Web Services, allow startups to create low cost apps for consumers and businesses. Apple’s iOS operating system and Google’s Android platform enable computing power and access to information we could not even dream of a few years ago. We see many companies now thinking more broadly about the ecosystem they operate in and how they can be platforms for their customers and partners.

Making the complex simple: Apple’s strength in making the complex simple and easy to use by the masses is a trend we see showing up across several other areas of technology. For example, enterprise software, once complicated and buried in computer programming code, is now accessible by employees with iPads. This simplification and consumerization has broad implications for adoption and growth of technology products and services, and ultimately the global economy.

Driving insight from data: Insight from data analysis is becoming a core competency for many companies in many industries. We are beginning to see leaders emerge in sectors like retail and financials based on their ability to understand and leverage data to create better products and happier customers. In the retail sector some particularly interesting technology developments are starting to have a large impact. Forward thinking retailers leveraging the latest analytics and electronic payment platforms, such as PayPal (owned by eBay), are able to gather data to create more loyal customers while spending less on marketing; or better yet taking marketing dollars and putting them directly in consumer pockets in the form of coupons and rebates. Technology that makes this possible requires heavy investment in software, storage, and new in store devices – leveraging the products of many companies we invest in the Janus Global Technology Fund such as Apple, EMC, NetApp, Teradata, eBay, and Qlik Technologies.

Now that I think about it, I may just ignore my diet app and my shopping list app and run to 7-11 tonight for my ice cream, after all, it is closer...so much for Homo economicus!

Detractors from Performance

Chinese travel company Ctrip.com International was the most significant individual detractor. The company experienced margin pressures on some of its business lines during the period from competitors seeking to gain market share. We do not believe such competition will negatively impact Ctrip.com materially long term due its strong market position. We think Ctrip.com is well positioned to benefit from a burgeoning travel industry. As GDP per capita continues to grow in China, domestic and international travel will increase as well. Ctrip has a competitive advantage with its large network of sales agents who collect cash and issue tickets for air travel and hotels. We also think it will benefit from the Chinese government’s continued strong promotion of domestic travel.

Solar module component maker STR Holdings traded lower after reporting lower-than-expected results. The timing of the solar market recovery will be much slower than we anticipated and we are less optimistic when STR’s customers will begin making substantial orders again; therefore, we sold our position.

Finally, Iron Mountain was also weak during the period. We believe this provider of document storage services can maintain its highly recurring and predictable revenues and pricing power given its dominant market position. Iron Mountain continues to generate significant free cash flow with which it has been buying back stock. We also think there’s a chance the company could convert to a real estate investment trust, which could significantly boost the stock price.

Contributors to Performance

Among individual contributors, Apple benefited from a strong earnings report, driven by significant iPhone and iPad sales. The computer and mobile device maker also initiated its first dividend and share repurchase program during the period. Apple has been the beneficiary of incremental sales opportunities over the past few years from new geographies (such as China), phone service carriers and products (such as iPad). We think it continues to have strong opportunities as its ecosystem continues to grow; its products reach new countries; and lower price points draw new customers. Apple continues to execute its business plan extremely well, and its stock remains reasonably valued, in our view.

Microsoft, another key contributor, also reported better-than-expected earnings although revenue growth came in below estimates. We think Microsoft will benefit from its Windows 8 launch later this year, a strong shift to

multi-year agreements and services (now the majority of the enterprise revenues) and significant traction in key lock-in products like System Center. Windows 8 has the potential to be a strong competitor on desktops, laptops, tablets, and smart phones, and Microsoft’s XBOX platform is gaining share and expanding product offerings in the living room.

Additionally, Amphenol aided performance. We favor the maker of electrical and fiber optic connectors for its competitive position in that it produces historically relatively low-cost, uniquely-designed products that are unlikely to be replaced once they are included in a product (autos, computers etc.). The business model has enabled the company to grow with good margins; it has also served a diversified base of customers, so it has not been too heavily exposed to any one sector or industry.

Derivatives

We initiated and owned positions in futures contracts and derivatives, such as options, in order to help mitigate the risks and potentially enhance the performance of the Fund. During the period, these positions in aggregate contributed to performance. (Please see “Notes to Financial Statements” for information about the hedging techniques used by the Fund.)

Thank you for your investment in Janus Global Technology Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), derivatives, and short sales. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund may at times have significant exposure to certain industry groups, which may react similarly to market developments (resulting in greater price volatility). The Fund also may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of one or more other share classes of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations and waivers. If each share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Janus International Equity Fund (unaudited)

Fund Snapshot
We invest in international companies that we believe have a sustainable competitive advantage, high or improving returns on capital and long-term growth. We invest where we believe we have differentiated research, in an effort to deliver superior risk-adjusted results over the long term.

Performance Overview

Janus International Equity Fund’s Class I Shares returned 18.77% over the six-month period ended March 31, 2012. The Fund’s primary benchmark, the MSCI EAFE Index, returned 14.56%, and its secondary benchmark, the MSCI All Country World ex-U.S. Index, returned 15.37% during the period.

Market Environment

We believe that the fourth quarter of 2011 will prove to have been the inflection point for European stock markets. National governments, the European Central Bank (ECB) and the European Commission have been taking small steps toward what we hope are lasting structural and fiscal improvements. On the political front, Italy and Spain have newly elected leaders who have been instrumental in forming their nations’ recovery plans.

The ECB’s decision to inject liquidity through its Long Term Refinancing Operation (LTRO) took a significant amount of fear out of the market. The action removed to a large extent the risk of the financial system freezing up and related effects it might have had in a Lehman-style global crisis. With fear easing, investors looked more closely at valuations and invested on company fundamentals, which led to a broad-based rally. In general, stock correlations declined and the market moved away from the risk-on, risk-off trade so prevalent in recent years.

In Asia, investors moved from concerns over inflation to worries that China could experience a hard economic landing from government tightening policies. China announced the reserve requirement ratio for its banks would be lowered in an effort to boost liquidity after having raised the ratio six times during 2011. In India, industrial production stopped growing, which surprised investors and contributed to continued weakness in that market.

Also notable was the Bank of Japan’s (BOJ) decision for the first time to target inflation in setting monetary policy. The central bank substantially increased the size of its quantitative easing program or bond purchasing program and committed to implement this by the end of the year. It is clear that not only is the BOJ going to target inflation, but also the yen to help the country’s exporters regain their competitiveness.

Performance Overview

Among individual contributors, chemicals maker LyondellBasell’s shares rallied over 108.39%. Ethane, a raw material used in the production of ethylene, dropped the most in five months, improving profitability for the company. The large chemical producer has a cost advantage since the primary input to its production process is natural gas, a commodity that has experienced considerable price pressure due to excess supply. We also feel the company’s management team is return-on-capital driven and disciplined on investing in its business. Lyondell announced a special dividend during the period and bought back its high-cost debt with cash and refinanced some of it at lower costs, all of which were value creating moves in our view.

Our holdings in Japan were also a key contributor, led by our holdings in Isuzu Motors. The truck maker benefited from increased market expectations for its earnings. Isuzu has a strong market position in mid and light-duty trucks in emerging markets (particularly Southeast Asia and the Middle East), where demand is growing significantly, in our view. Due to shrinkage in the Japanese truck market, there’s also significant amount of spare capacity in its domestic market. Additionally, Isuzu has benefited by reducing costs during the global financial crisis. As a result, the high incremental margins available from putting Isuzu’s spare capacity to work are driving rapid earnings growth while the valuation remains compelling.

On a country basis, our U.K. holdings were the largest contributors led by insurer Prudential, which also recorded significant gains as part of a general rebound in the financial sector late in the period and a strong earnings report driven by better-than-expected results in Asia. We

continue to believe the U.K. insurer is outperforming its peers in Asia.

Relative detractors were led by our holdings in India, where delays in government approvals stalled major infrastructure projects and negatively impacted energy conglomerate Reliance Industries and Adani Enterprises, a coal producer. We think the scale and complexity of Reliance’s refineries could result in significantly better-than-industry average refining margins. We also believe that the company’s offshore oil and gas fields offer potentially significant increases in oil and gas reserves and production growth. We like Adani for its integrated approach involving coal mining, coal logistics and power generation to power transmission. Adani is uniquely positioned, in our view, to better mine domestic coal and transport it from the Eastern India coal belt to the Western India power plants via its rail and port facilities.

Chinese travel company Ctrip.com International was the most significant individual detractor. The company experienced margin pressures on some of its business lines during the period from competitors seeking to gain market share. We do not believe such competition will negatively impact Ctrip.com materially long term due its strong market position. We think Ctrip.com is well positioned to benefit from a burgeoning travel industry. As GDP per capita continues to grow in China, domestic and international travel will increase as well. Ctrip has a competitive advantage with its large network of sales agents who collect cash and issue tickets for air travel and hotels. We also think it will benefit from the Chinese government’s continued strong promotion of domestic travel.

Japanese electronics retailer Yamada Denki also weighed on performance. The company’s comparable sales lagged year-over-year due to significant digital TV sales last year after the country ended its analog signal conversion and forced consumers to upgrade. We felt the short-term TV cycle should have been priced into the stock, but it apparently wasn’t. We took advantage of the price weakness by adding to our position. As the dominant consumer electronics retailer in Japan, Yamada Denki continues to gain market share, and it is stronger than competitors in terms of profitability and balance sheet strength. The company also benefits from its size in terms of making purchases on better terms than competitors.

Please see the Derivative Instruments section in the “Notes to Financial Statements” for derivatives used by the Fund.

Outlook

In Europe, we are concerned higher oil prices could have a further deteriorating impact on an economy that already is likely in a recession. Germany is the continent’s one area of strength, but since half of its exports are to other European countries it may be difficult for it to avoid a recession as well. Tighter fiscal budgets and higher taxes will continue to weigh on consumption. Countries of particular concern to us are Spain, Italy and France. In general, we expect the second half of the year to be weaker than the first half for the region.

Conversely, we think the first quarter will mark the low point for China’s economy this year and expect a stronger performance in the second half of the year when stimulus measures should have a more meaningful impact. China reduced its growth expectations to 7.5% annual GDP growth from the 8% it had used the previous eight years, but we feel that is less of a concern than the market seems to believe since it aligned with the Chinese Government’s five-year plan. We continue to believe China will avoid a hard landing, which is the biggest fear for people investing in Asia.

We have become more optimistic on Japan based on the change in monetary policy that coincides with global manufacturing data turning up, a key driver of the country’s economy historically. Reconstruction from last year’s earthquake and tsunami should also drive demand. We increased our weighting in Japan from 16% to 21% by establishing a position in a motorcycle manufacturer and adding to our position in a heating and air conditioning provider, among other additions to the Fund.

Thank you for your investment in Janus International Equity Fund.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund may invest in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares, Class I Shares, Class R Shares, Class S Shares and Class T Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 was calculated using the performance and the fees and expenses of one or more other share classes of a predecessor fund(s), accounting for, when applicable and permitted, any fee and expense limitations and waivers. If each respective share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010. The performance shown for Class D Shares for periods prior to February 16, 2010 reflects the performance of the Fund’s Class I Shares. The performance shown reflects the fees and expenses of Class D Shares, without the effect of any fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class I Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

November 30, 2006 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

A non-recurring expense adjustment impacted the ratio for Class S Shares. The expenses paid during the period would have been $7.93 for Class S Shares without the non-recurring expense adjustment.

Janus Overseas Fund (unaudited)

Fund Snapshot
I believe that company fundamentals drive share prices over the long term. I use fundamental research to make high-conviction, long-term investments in the most compelling international growth companies regardless of geography.

Brent Lynn
portfolio manager

Performance

Janus Overseas Fund’s Class T Shares returned 20.28% over the six-month period ended March 31, 2012. The Fund’s primary benchmark, the MSCI All Country World ex-U.S. Index, returned 15.37%, and its secondary benchmark, the MSCI EAFE Index, returned 14.56% during the period.

Economic Update

Global equity markets moved broadly higher during the period thanks to an easing of concerns in Europe. While the region is still far from solving its sovereign debt issues, liquidity measures taken by the European Central Bank in December and moves towards a closer fiscal union helped ease the market’s fear of a Lehman-style collapse. In addition, German and French leaders demonstrated the need for comprehensive measures, while indebted lynchpin countries, Italy and Spain, have new leadership in place to potentially implement meaningful structural reforms in areas such as pensions and labor policies. Another bailout for beleaguered Greece also aided market sentiment.

Emerging markets rebounded from a weak performance in 2011 due to better clarity in Europe and reduced inflation in key countries: India, China and Brazil. Lower inflation should allow for more flexibility in fiscal and monetary policies. Brazil benefited from moves by its central bank to lower interest rates following easing in inflationary pressures. We also began to see signs that the Indian Government may move forward to address some of the bottlenecks that have impeded important infrastructure development. These positives were somewhat offset by rising oil prices.

Portfolio Positioning

While always opportunistic, Janus Overseas Fund has taken a particularly contrarian approach over the past few years. We added significant investments in beaten up financial stocks, cyclical stocks, and emerging market stocks. This approach achieved some success in prior years, but in the 2011 environment of extreme risk aversion, contrarian investing clearly did not work. A number of these stocks saw a minor rebound during the first quarter of 2012, as investors’ risk aversion declined.

The global economic slowdown is easing inflationary pressures in emerging markets and should allow for some relaxation of monetary policies in these countries. Also, I believe that European leaders finally have realized that a comprehensive approach to sovereign debt issues is the only way to prevent the crisis from spreading to the core of Europe. Most importantly for the Fund, I see a tremendous disconnect between the intrinsic value of many of our key companies and their stock prices. I believe we have invested in a number of strong companies that have attractive valuations and that can emerge as long-term winners in their industries. I am optimistic that over time the valuations of our companies will not be based on indiscriminate market fear, but on earnings, cash flows, and business fundamentals. During the difficult market environment in recent years, I tried to concentrate the Fund in our highest conviction ideas. I believe that our top holdings have strong, durable franchises and compelling valuations.

Although they are within the guidelines of the Fund, our positions in the U.S. warrant discussion. Janus Overseas Fund is opportunistic and has made investments in special situations companies and at times in the U.S. In the aftermath of the 2008 global financial crisis and subsequent global economic downturn, I found a greater number of special situations than usual and a number of them were U.S.-based companies. Our U.S. exposure rose. More recently, the Fund’s weight in the U.S. declined when I sold holdings in Bank of America, Nabors Industries and Yahoo.

Contributors to Performance

Hong Kong-based Li & Fung, the global leader in sourcing logistics for retailers and the Fund’s largest holding, was the top individual contributor during the period. I think Li &

Janus Global & International Funds | 75

Janus Overseas Fund (unaudited)

Fung has strong organic growth opportunities as U.S. and European retailers outsource more in order to focus on their core competencies. The company also has the opportunity to significantly expand its business with Wal-Mart.

Some U.S. holdings, such as Delta Air Lines and Ford, were also among top contributors during the period after lagging in 2011. These companies performed better as the U.S. economy showed signs of improvement. Despite rising oil prices, Ford and the airlines have improved the structural profitability of their businesses and have the potential to generate significant cash flow.

Detractors from Performance

India, which was among the weakest performing large markets in the world for 2011, desperately needs to implement a wide variety of infrastructure projects and other economic reforms. A well-intentioned, grass roots campaign to expose government corruption, however, fostered an environment where politicians and bureaucrats were reluctant to approve projects or change policies. Inflation also remained higher than desired. This environment hurt our core Indian holdings, specifically Adani Enterprises, Reliance Industries and DLF. I still believe in the long-term opportunities for these companies.

Reliance has strong competitive advantages in its refining and petrochemical businesses. Also, there are signs that the Indian government may move forward with offshore energy project approvals and changes towards a more market oriented gas pricing regime. Adani’s integrated approach involving coal mining, coal logistics and power generation position the company to take advantage of the huge long-term growth in electrical demand in India. The largest real estate company in India, DLF has a strong land bank, especially in the Delhi region, and a long-term record of successful project execution.

Derivatives

In aggregate, derivatives contributed to performance during the period. In addition to a currency hedge on the Japanese yen, the Fund also very selectively utilized swaps and options during the period. Reasons for using these instruments included hedging downside risks, achieving market access, and establishing positions more quickly. Please see the Derivative Instruments section in the “Notes to Financial Statements” for derivatives used by the Fund.

Outlook

The global macro environment, while improved from the heights of uncertainty last fall, remains unclear and a source of volatility to the portfolio. We are trying to look beyond the short-term environment to focus on companies with attractive long-term business opportunities and compelling valuations. I cannot predict when global macro fears will subside, but I have positioned the Fund for a period of lower risk premiums and greater investor focus on company fundamentals and valuation. This includes a high exposure to rapidly growing companies in emerging markets such as China, India, and Brazil. This also includes a high exposure to slower growing companies in developed markets trading at very compelling valuations.

Thank you for your continued investment in Janus Overseas Fund.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

Janus Overseas Fund held approximately 12.2% and 14.1% of its investments in Brazilian and Indian securities, respectively, as of March 31, 2012, and the Fund may have experienced significant gains or losses due, in part, to its investments in Brazil and India. While holdings are subject to change without notice, the Fund’s returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in Brazil and India.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

The Fund will normally invest at least 80% of its net assets, measured at the time of purchase, in the type of securities described by its name.

Class A Shares, Class C Shares, Class R Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of one or more other share classes of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations and waivers. If each share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

May 5, 1994 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

Janus Worldwide Fund (unaudited)

Fund Snapshot
Janus Worldwide Fund invests globally, seeking companies with competitive advantages that lead to improving returns on capital and sustainable long-term growth. We invest where we possess differentiated research insights in an effort to deliver superior risk-adjusted results over time.

George Maris
portfolio manager

Performance

Janus Worldwide Fund’s Class T Shares returned 21.17% over the six-month period ended March 31, 2012, while its primary benchmark, the MSCI World Index, returned 20.03%. The Fund’s secondary benchmark, the MSCI All Country World Index, returned 19.91%.

Market Environment

Global equity markets benefited from easing concerns over the European sovereign debt crisis, particularly regarding a disorderly Greek default, as well as optimism from improving U.S. economic data. The combination of European Central Bank activities, led by its liquidity program (Long-Term Refinancing Operations or LTRO), a successful restructuring of Greek debt and stability in the U.S. housing market helped increase investors’ willingness to take risk and boosted corporate activity. Other positives included the Bank of Japan’s plans to target inflation and weaken its currency to stimulate its export-led economy. The Bank of China’s loosening reserve requirements in an effort to stimulate lending and the Central Bank of Brazil’s decision to lower interest rates to spur growth also aided sentiment. By and large the world’s major central banks eased monetary policy to stabilize, if not stimulate, their economies.

Performance Overview

Our financial holdings were the largest contributors to relative performance. We believed our holdings in general were significantly levered to a rebound in confidence, particularly our financial holdings. U.S. banks JPMorgan Chase, Citigroup and Morgan Stanley were among the Fund’s largest individual contributors. We made a concerted effort to deploy capital to those financials we felt were in substantially better shape than the market price reflected. We added to these companies during December when the selling pressure was most intense and trimmed as they rallied significantly during the first quarter of 2012.

Comcast was also a key contributor. The company is using its leading position in cable to grow market share and returns. In the cable side of its business, it is offering more attractive entertainment options to grow and retain customers. These options include rolling out new set top boxes with a more intuitive and helpful feature set, contracting with key content providers, such as Disney, to ensure high-quality content will be available to its customers, and facilitating content use with traditional cable television as well as broadband video. We appreciate these actions should lead to greater customer capture, allowing Comcast to further penetrate its customer base with additional offerings in broadband and telecommunications, in addition to new products like home security. The NBC Universal acquisition is also generating significant synergies via cost reductions and better content experiences. Lastly, management is aggressively employing a disciplined capital allocation program, where new investments and acquisitions are considered along with a commitment to material buybacks and dividends.

Our Indian holdings weighed the most on relative performance. The governmental gridlock resulting from a scandal over telecommunication licenses and a general investigation into corruption hurt our holdings. In addition, India’s persistent inflation prevented monetary responses at a time of global economic weakness. Our holdings in Indian industrial Jain Irrigation Systems and Educomp Solutions, an Indian education company, fell. We think the fundamentals for both companies remain strong in terms of long-term growth and competitive positions, but continued political stagnation and inflation remain issues. We reduced our exposure to India by eliminating one holding with direct exposure to real estate and utilities, two industries that are most adversely affected by the current environment. Our belief is that once this negative environment improves, the market valuations will reflect the earnings power of our holdings.

Energy wholesale provider NRG Energy was the largest individual detractor. The price of energy is linked with the price of natural gas prices, which remained weak. We trimmed our position, as we assess the company’s longer

term growth profile given the abundance of U.S. natural gas supply.

Please see the Derivative Instruments section in the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Outlook

We remain positive on equity markets given the wide range of promising developments we saw during the period, which has led to greater investor confidence and a reduction in the equity risk premium. At the same time, we see modest growth in the U.S. and more significant growth in emerging markets, particularly China and Brazil. The Chinese Government’s projection of slowing GDP growth, while a concern to some investors, is more about its evolution in becoming the second largest economy in the world. We also believe the U.S. banking system’s demonstrated resilience in the Federal Reserve’s recent stress tests, using a recessionary environment more severe than the last, also boosted confidence in the market. Meanwhile, an apparent bottoming in the U.S. housing market provides stability since the home is typically an individual’s largest single investment. While the macroeconomic picture has improved, we also see risks from increasing populist political rhetoric as we near the U.S. elections in November. Among emerging markets, we are less optimistic that India’s government will be able to stimulate economic growth through its fiscal policies.

Thank you for your continued support of Janus Worldwide Fund.

Performance shown for Class A Shares at Maximum Offering Price (MOP) includes the Fund’s maximum sales charge of 5.75%. Performance shown at Net Asset Value (NAV) does not include this charge and would have been lower had this charge been taken into account.

Performance shown for Class C Shares includes a 1% contingent deferred sales charge (CDSC) on periods of less than 12 months. Performance shown at Net Asset Value (NAV) does not include this sales charge and would have been lower had this sales charge been taken into account.

Net expense ratios reflect the expense waiver, if any, Janus Capital has contractually agreed to through February 1, 2013.

The Fund has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period. See the Fund’s Prospectus or Statement of Additional Information for more details.

The Fund’s performance may be affected by risks that include those associated with investments in specific industries or countries and potential conflicts of interest with the Janus “funds of funds.” Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings (“IPOs”), and derivatives. Please see a Janus prospectus or janus.com/info (or janus.com/reports if you hold shares directly with Janus Capital) for more information about risks, portfolio holdings and other details.

The Fund invests in derivatives which can be highly volatile and involve additional risks than if the underlying securities were held directly by the Fund. Such risks include gains or losses which, as a result of leverage, can be substantially greater than the derivatives’ original cost. There is also a possibility that derivatives may not perform as intended which can reduce opportunity for gains or result in losses by offsetting positive returns in other securities the Fund owns.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

The Fund may have significant exposure to emerging markets. In general, emerging market investments have historically been subject to significant gains and/or losses. As such, the Fund’s returns and NAV may be subject to volatility.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

Class A Shares, Class C Shares, Class R Shares and Class S Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of one or more other share classes of the Fund, calculated using the fees and expenses of each respective share class without the effect of any fee and expense limitations and waivers. If each share class of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund’s commencement of Class D Shares, reflects the fees and expenses of Class D Shares, net of any fee and expense limitations or waivers.

Class I Shares of the Fund commenced operations on July 6, 2009. The historical performance shown for periods prior to July 6, 2009 reflects the performance of a prior share class of the Fund, without the effect of any fee and expense limitations or waivers. If Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different. Please refer to the Fund’s prospectus for further details concerning historical performance.

Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested and do not include the effect of loads.

Ranking is for Class T Shares only; other classes may have different performance characteristics. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

May 16, 1991 is the date used to calculate the since–inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the indices. The indices are unmanaged and are not available for direct investment; therefore, their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

Notes to Financial Statements (unaudited)

The following section describes the organization and significant accounting policies and provides more detailed information about the schedules and tables that appear throughout this report. In addition, the Notes to Financial Statements explain the methods used in preparing and presenting this report.

1.  Organization and Significant Accounting Policies

Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Research Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund and Janus Worldwide Fund (individually, a “Fund” and collectively, the “Funds”) are series funds. The Funds are part of Janus Investment Fund (the “Trust”), which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The financial statements include information for the six-month period ended March 31, 2012. The Trust offers forty-five funds which include multiple series of shares, with differing investment objectives and policies. The Funds invest primarily in equity securities. Each Fund in this report is classified as diversified, as defined in the 1940 Act, with the exception of Janus Global Select Fund, which is classified as nondiversified.

Each Fund in this report offers multiple classes of shares in order to meet the needs of various types of investors. Each class represents an interest in the same portfolio of investments. Certain financial intermediaries may not offer all classes of shares.

Class A Shares and Class C Shares are generally offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. The maximum purchase in Class C Shares is $500,000 for any single purchase.

Class D Shares are generally no longer being made available to new investors. The Shares are available only to investors who hold accounts directly with the Janus funds and to immediate family members or members of the same household of an eligible individual investor. The Shares are not offered through financial intermediaries.

Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, and bank trust platforms, as well as certain retirement platforms. Class I Shares are also available to certain institutional investors including, but not limited to, corporations, certain retirement plans, public plans, and foundations/endowments.

Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms.

Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with Janus Capital Management LLC (“Janus Capital”) or its affiliates to offer Class S Shares on their supermarket platforms.

Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with Janus Capital or its affiliates to offer Class T Shares on their supermarket platforms.

The following accounting policies have been followed by the Funds and are in conformity with accounting principles generally accepted in the United States of America within the investment management industry.

Investment Valuation

Securities are valued at the last sales price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities traded on over-the-counter (“OTC”) markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees. Short-term securities with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Short positions shall be valued in accordance with the same methodologies, except that in the event that a last sale price is not available, the latest ask price shall be used instead of a bid price. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect as of the daily close of the New York Stock Exchange (“NYSE”). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the Funds are identified between the closing of their principal markets and the time the net asset value (“NAV”) is determined, securities

Janus Global & International Funds | 137

Notes to Financial Statements (unaudited) (continued)

may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Funds’ Trustees. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a nonsignificant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. Restricted and illiquid securities are valued in accordance with procedures established by the Funds’ Trustees.

Investment Transactions and Investment Income

Investment transactions are accounted for as of the date purchased or sold (trade date). Dividend income is recorded on the ex-dividend date. Certain dividends from foreign securities will be recorded as soon as the Trust is informed of the dividend, if such information is obtained subsequent to the ex-dividend date. Dividends from foreign securities may be subject to withholding taxes in foreign jurisdictions. Interest income is recorded on the accrual basis and includes amortization of premiums and accretion of discounts. Gains and losses are determined on the identified cost basis, which is the same basis used for federal income tax purposes. Income, as well as gains and losses, both realized and unrealized, are allocated daily to each class of shares based upon the ratio of net assets represented by each class as a percentage of total net assets.

Expenses

Each Fund bears expenses incurred specifically on its behalf, as well as a portion of general expenses, which may be allocated pro rata to each Fund. Each class of shares bears expenses incurred specifically on its behalf and, in addition, each class bears a portion of general expenses, which are allocated daily to each class of shares based upon the ratio of net assets represented by each class as a percentage of total net assets. Expenses directly attributable to a specific class of shares are charged against the operations of such class.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held at the date of the financial statements. Net unrealized appreciation or depreciation of investments and foreign currency translations arise from changes in the value of assets and liabilities, including investments in securities held at the date of the financial statements, resulting from changes in the exchange rates and changes in market prices of securities held.

Currency gains and losses are also calculated on payables and receivables that are denominated in foreign currencies. The payables and receivables are generally related to foreign security transactions and income translations.

Foreign currency-denominated assets and forward currency contracts may involve more risks than domestic transactions, including currency risk, political and economic risk, regulatory risk and equity risk. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar.

Dividend Distributions

The Funds generally declare and distribute dividends of net investment income and realized capital gains (if any) annually. The majority of dividends and capital gains distributions from the Funds may be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

The Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It is quite common for these dividends to exceed the REITs’ taxable earnings and profits, resulting in the excess portion of such dividends being designated as a return of capital. If the Funds distribute such amounts, such distributions could constitute a return of capital to shareholders for federal income tax purposes.

Federal Income Taxes

No provision for income taxes is included in the accompanying financial statements as the Funds intend to

138 | MARCH 31, 2012

distribute to shareholders all taxable investment income and realized gains and otherwise comply with Subchapter M of the Internal Revenue Code applicable to regulated investment companies.

In accordance with the Financial Accounting Standards Board (“FASB”) guidance, the Funds adopted the provisions of “Income Taxes.” These provisions require an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that, based on the technical merits, have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense on the Statements of Operations.

These provisions require management of the Funds to analyze all open tax years, as defined by the Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the period ended March 31, 2012, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examinations in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Modernization Act”) was signed by the President. The Modernization Act is the first major piece of legislation affecting Regulated Investment Companies (“RICs”) since 1986 and it modernizes several of the federal income and excise tax provisions related to RICs. Some of the enacted provisions include:

New capital losses may now be carried forward indefinitely, and retain the character of the original loss. Under pre-enactment law, capital losses could be carried forward for eight years, and carried forward as short-term capital, irrespective of the character of the original loss.

The Modernization Act contains simplification provisions, which are aimed at preventing disqualification of a RIC for “inadvertent” failures of the asset diversification and/or qualifying income tests. Additionally, the Modernization Act exempts RICs from the preferential dividend rule, and repeals the 60-day designation requirement for certain types of pay-through income and gains.

Finally, the Modernization Act contains several provisions aimed at preserving the character of distributions made by a fiscal year RIC during the portion of its taxable year ending after October 31 or December 31, reducing the circumstances under which a RIC might be required to file amended Forms 1099 to restate previously reported distributions.

Except for the simplification provisions related to RIC qualification, the Modernization Act is effective for taxable years beginning after December 22, 2010. The provisions related to RIC qualification are effective for taxable years for which the extended due date of the tax return is after December 22, 2010.

Restricted Cash

As of March 31, 2012, Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Life Sciences Fund, Janus Global Select Fund, Janus Global Technology Fund, Janus International Equity Fund, Janus Overseas Fund and Janus Worldwide Fund had restricted cash in the amounts of $77,650, $1,685,136, $100,000, $12,955,443, $1,969,301, $300,000, $84,158,762 and $950,000, respectively. The restricted cash represents collateral received in relation to options contracts invested in by the Funds at March 31, 2012. The restricted cash is held at the Funds’ custodian, State Street Bank and Trust Company. The carrying value of the restricted cash approximates fair value.

Valuation Inputs Summary

In accordance with FASB guidance, the Funds utilize the “Fair Value Measurements” to define fair value, establish a framework for measuring fair value, and expand disclosure requirements regarding fair value measurements. The Fair Value Measurement Standard does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. This standard emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. Various inputs are used in determining the value of the Funds’ investments defined pursuant to this standard. These inputs are summarized into three broad levels:

Level 1 – Quoted prices in active markets for identical securities.

Level 2 – Prices determined using other significant observable inputs. Observable inputs are inputs that reflect the assumptions market participants would use in pricing a security and are developed based on market data obtained from sources independent of the reporting entity. These may include quoted prices

Janus Global & International Funds | 139

Notes to Financial Statements (unaudited) (continued)

for similar securities, interest rates, prepayment speeds, credit risk, and others.

Debt securities are valued in accordance with the evaluated bid price supplied by the pricing service and generally categorized as Level 2 in the hierarchy. Securities traded on OTC markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds’ Trustees and are categorized as Level 2 in the hierarchy. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value and are categorized as Level 2 in the hierarchy. Other securities that are categorized as Level 2 in the hierarchy include, but are not limited to, preferred stocks, bank loans, American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs), warrants, swaps, investments in mutual funds, OTC options, and forward contracts. The Funds may use systematic fair valuation models provided by independent third parties to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. These are generally categorized as Level 2 in the hierarchy.

Level 3 – Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable or deemed less relevant (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the factors market participants would use in pricing the security and would be based on the best information available under the circumstances.

For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used in employing valuation techniques such as the market approach, the income approach, or the cost approach, as defined under the FASB Guidance. These are categorized as Level 3 in the hierarchy.

There have been no significant changes in valuation techniques used in valuing any such positions held by the Funds since the beginning of the fiscal period.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of inputs used as of March 31, 2012 to value the Funds’ investments in securities and other financial instruments is included in the “Valuation Inputs Summary” and “Level 3 Valuation Reconciliation of Assets” (if applicable) in the Notes to Schedules of Investments.

The Funds adopted FASB Accounting Standards Update “Fair Value Measurements and Disclosures” (the “Update”). This Update applies to a Fund’s disclosures about transfers in and out of Level 1 and Level 2 of the fair value hierarchy and the reasons for the transfers. Disclosures about the valuation techniques and inputs used to measure fair value for investments that fall in either Level 2 or Level 3 fair value hierarchy are summarized under the Level 2 and Level 3 categories listed above.

The following table shows transfers between Level 1 and Level 2 of the fair value hierarchy during the period ended March 31, 2012.

	Transfers In		Transfers Out
	Level 1 to		Level 2
Fund	Level 2		to Level 1
Janus Asia Equity Fund	$	–	$	2,265,723
Janus Emerging Markets Fund		–		4,005,980
Janus Global Life Sciences Fund		–		48,690,583
Janus Global Research Fund		–		55,915,776
Janus Global Select Fund		–		668,547,030
Janus Global Technology Fund		–		105,346,487
Janus International Equity Fund		–		141,968,539
Janus Overseas Fund		–		5,103,484,995
Janus Worldwide Fund		–		649,293,497

Financial assets were transferred from Level 2 to Level 1 since certain foreign equity prices were applied a fair valuation adjustment factor at the beginning of the fiscal year and no factor was applied at the end of the period.

The Funds recognize transfers between the levels as of the beginning of the fiscal period.

In May 2011, the FASB issued Accounting Standards Update, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements.” This disclosure will become effective for interim and annual periods beginning after December 15, 2011. The Accounting Standards Update requires disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Funds shall provide quantitative information about the significant unobservable inputs used in the fair value measurement. To meet the objective of the quantitative disclosure, the Funds may need to further disaggregate to provide more meaningful information about the significant unobservable inputs used and how these inputs vary over time.

140 | MARCH 31, 2012

The Funds are not required to create quantitative information to comply with this disclosure requirement if quantitative unobservable inputs are not developed by the Funds when measuring fair value (for example, when a Fund uses prices from prior transactions or third-party pricing information without adjustment). However, when providing this disclosure, the Funds cannot ignore quantitative unobservable inputs that are significant to the fair value measurement and are reasonably available to the Funds.

In addition, the Accounting Standards Update requires the Funds to provide a narrative sensitivity disclosure of the fair value measurement changes in unobservable inputs and the interrelationships between those unobservable inputs for fair value measurements categorized with Level 3 of the fair value hierarchy.

2.  Derivative Instruments

The Funds may invest in various types of derivatives, which may at times result in significant derivative exposure. A derivative is a financial instrument whose performance is derived from the performance of another asset. The Funds may invest in derivative instruments including, but not limited to: futures contracts, put options, call options, options on future contracts, options on foreign currencies, swaps, forward contracts, structured investments, and other equity-linked derivatives. Each derivative instrument that was held by one or more of the Funds during the period ended March 31, 2012 is discussed in further detail below. A summary of derivative activity by Fund is reflected in the tables at the end of this section.

The Funds may use derivative instruments for hedging (to offset risks associated with an investment, currency exposure, or market conditions) or for speculative (to seek to enhance returns) purposes. When the Funds invest in a derivative for speculative purposes, the Funds will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. The Funds may not use any derivative to gain exposure to an asset or class of assets in which they would be prohibited by their respective investment restrictions from purchasing directly. The Funds’ ability to use derivative instruments may also be limited by tax considerations.

Investments in derivatives in general are subject to market risks that may cause their prices to fluctuate over time. Investments in derivatives may not directly correlate with the price movements of the underlying instrument. As a result, the use of derivatives may expose the Funds to additional risks that they would not be subject to if they invested directly in the securities underlying those derivatives. The use of derivatives may result in larger losses or smaller gains than otherwise would be the case. Derivatives can be volatile and may involve significant risks, including, but not limited to, counterparty risk, credit risk, currency risk, equity risk, index risk, interest rate risk, leverage risk, and liquidity risk, as described below.

Derivatives may generally be traded OTC or on an exchange. Derivatives traded OTC, such as options and structured notes, are agreements that are individually negotiated between parties and can be tailored to meet a purchaser’s needs.

OTC derivatives are not guaranteed by a clearing agency and may be subject to increased credit risk. In an effort to mitigate credit risk associated with derivatives traded OTC, the Funds may enter into collateral agreements with certain counterparties whereby, subject to certain minimum exposure requirements, a Fund may require the counterparty to post collateral if the Fund has a net aggregate unrealized gain on all OTC derivative contracts with a particular counterparty. There is no guarantee that counterparty exposure is reduced and these arrangements are dependent on Janus Capital’s ability to establish and maintain appropriate systems and trading.

In pursuit of their investment objectives, each Fund may seek to use derivatives to increase or decrease exposure to the following market risk factors:

•  Counterparty Risk – Counterparty risk is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to a Fund.

•  Credit Risk – Credit risk is the risk an issuer will be unable to make principal and interest payments when due, or will default on its obligations.

•  Currency Risk – Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

•  Equity Risk – Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

•  Index Risk – If the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, a Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they

Janus Global & International Funds | 141

Notes to Financial Statements (unaudited) (continued)

increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

•  Interest Rate Risk – Interest rate risk is the risk that the value of fixed-income securities will generally decline as prevailing interest rates rise, which may cause a Fund’s NAV to likewise decrease, and vice versa.

•  Leverage Risk – Leverage risk is the risk associated with certain types of leveraged investments or trading strategies pursuant to which relatively small market movements may result in large changes in the value of an investment. A Fund creates leverage by using borrowed capital to increase the amount invested, or investing in instruments, including derivatives, where the investment loss can exceed the original amount invested. Certain investments or trading strategies that involve leverage can result in losses that greatly exceed the amount originally invested.

•  Liquidity Risk – Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

Forward Foreign Currency Exchange Contracts

A forward foreign currency exchange contract (“forward currency contract”) is an obligation to buy or sell a foreign currency at a future date at a negotiated rate. The Funds may enter into forward currency contracts for hedging purposes, including, but not limited to, reducing exposure to changes in foreign currency exchange rates on foreign portfolio holdings and locking in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. The Funds may also invest in forward currency contracts for nonhedging purposes such as seeking to enhance returns. The Funds are subject to currency risk in the normal course of pursuing their investment objectives through their investments in forward currency contracts.

The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract is included in “Net realized gain/(loss) from investment and foreign currency transactions” on the Statements of Operations (if applicable).

Forward currency contracts held by the Funds are fully collateralized by other securities, which are denoted on the accompanying Schedules of Investments (if applicable). The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts. Such collateral is in the possession of the Funds’ custodian.

Futures Contracts

A futures contract is an exchange-traded agreement to take or make delivery of an underlying asset at a specific time in the future for a specific predetermined negotiated price. The Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds are subject to interest rate risk, equity risk, and currency risk in the normal course of pursuing their investment objectives through their investments in futures contracts. The Funds may also use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between the values of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Futures contracts are marked-to-market daily, and the daily variation margin is recorded as a receivable or payable on the Statements of Assets and Liabilities (if applicable). When a contract is closed, a realized gain or loss is recorded as “Net realized gain/(loss) from futures contracts” on the Statements of Operations (if applicable), equal to the difference between the opening and closing value of the contract. Generally, futures contracts are marked-to-market (i.e., treated as realized and subject to distribution) for federal income tax purposes at fiscal year-end. Securities held by the Funds that are designated as collateral for market value on futures contracts are noted on the Schedules of Investments (if applicable). Such collateral is in the possession of the Funds’ custodian or with the counterparty broker.

With futures, there is minimal counterparty credit risk to the Funds since futures are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default.

Options Contracts

An options contract provides the purchaser with the right, but not the obligation, to buy (call option) or sell (put option) a financial instrument at an agreed upon price. The Funds may purchase or write covered and uncovered put and call options on swap contracts (“swaptions”), futures contracts, and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds are subject to interest rate risk, liquidity risk, equity risk, and currency risk in the normal course of pursuing their investment objectives through their investments in options contracts. The Funds may use options contracts to hedge

142 | MARCH 31, 2012

against changes in interest rates, the values of equities, or foreign currencies. The Funds may utilize American-style and European-style options. An American-style option is an option contract that can be exercised at any time between the time of purchase and the option’s expiration date. A European-style option is an option contract that can only be exercised on the option’s expiration date. The Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in long-term equity anticipation securities, which are long-term option contracts that can be maintained for a period of up to three years. The Funds may also enter into a swaption contract which grants the purchaser the right, but not the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. Entering into a swaption contract involves, to varying degrees, the elements of credit, market and interest rate risk, associated with both option contracts and swap contracts. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the Funds receive a premium and become obligated to sell or purchase the underlying security at a fixed price, upon exercise of the option. In writing an option, the Funds bear the risk of an unfavorable change in the price of the security underlying the written option. Exercise of an option written by the Funds could result in the Funds buying or selling a security at a price different from the current market value.

When an option is exercised, the proceeds on sales for a written call option, the purchase cost for a written put option, or the cost of the security for a purchased put or call option are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and OTC put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

Options traded on an exchange are regulated and the terms of the options are standardized. Options traded OTC expose the Funds to counterparty risk in the event that the counterparty does not perform. This risk is mitigated by having a netting arrangement between the Funds and the counterparty and by having the counterparty post collateral to cover the Funds’ exposure to the counterparty.

Holdings of the Funds designated to cover outstanding written options are noted on the Schedules of Investments (if applicable). Options written are reported as a liability on the Statements of Assets and Liabilities as “Options written at value” (if applicable). Realized gains and losses are reported as “Net realized gain/(loss) from written options contracts” on the Statements of Operations (if applicable).

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the options are exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the options are exercised. The risk in buying options is that the Funds pay a premium whether or not the options are exercised. The use of such instruments may involve certain additional risks as a result of unanticipated movements in the market. A lack of correlation between the value of an instrument underlying an option and the asset being hedged, or unexpected adverse price movements, could render the Funds’ hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. There is no limit to the loss the Funds may recognize due to written call options.

Swaps

A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The Funds may utilize swap agreements as a means to gain exposure to certain common stocks and/or to “hedge” or protect their portfolios from adverse movements in securities prices or interest rates. The Funds are subject to equity risk and interest rate risk in the normal course of pursuing their investment objectives through investments in swap contracts. Swap agreements entail the risk that a party will default on its payment obligation to a Fund. If the other party to a swap defaults, a Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Swap agreements traditionally were privately negotiated and entered into in the over-the-counter market. However, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) of 2010 now permits certain swap agreements to be cleared through a clearinghouse and traded on an exchange or swap execution facility. New regulations under the Dodd-Frank Act could, among other things, increase the cost of such transactions. Swap contracts of the Funds are reported as an asset or liability on the Statements of Assets and Liabilities (if applicable). Realized gains and losses of the Funds are reported in “Net realized gain/(loss) from swap contracts” on the Statements of Operations (if applicable).

Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset,

144 | MARCH 31, 2012

which includes both the income it generates and any capital gains over the payment period.

The Funds’ maximum risk of loss for total return swaps from counterparty risk or credit risk is the discounted value of the payments to be received from/paid to the counterparty over the contract’s remaining life, to the extent that the amount is positive. The risk is mitigated by having a netting arrangement between the Funds and the counterparty and by the posting of collateral to the Funds to cover the Funds’ exposure to the counterparty.

In accordance with FASB guidance, the Funds adopted the provisions for “Derivatives and Hedging,” which require qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements.

The following tables, grouped by derivative type, provide information about the fair value and location of derivatives within the Statements of Assets and Liabilities as of March 31, 2012.

3.  Other investments and strategies

Additional Investment Risk

It is important to note that events in both domestic and international equity and fixed-income markets have resulted, and may continue to result, in an unusually high degree of volatility in the markets, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected. These events and the resulting market upheavals may have an adverse effect on a Fund, such as a decline in the value and liquidity of many securities held by the Fund, unusually high and unanticipated levels of redemptions, an increase in portfolio turnover, a decrease in NAV, and an increase in Fund expenses. Because the situation is unprecedented and widespread, it may also be unusually difficult to identify both investment risks and opportunities, which could limit or preclude a Fund’s ability to achieve its investment objective. It is impossible to predict whether or for how long these conditions will continue. Therefore, it is important to understand that the value of your investment may fall, sometimes sharply, and you could lose money.

Further, the instability experienced in the financial markets has resulted in the U.S. Government and various other governmental and regulatory entities taking actions to address the financial crisis. These actions include, but are not limited to, the enactment of the Dodd-Frank Act which is expected to dramatically change the way in which the U.S. financial system is supervised and regulated. More specifically, the Dodd-Frank Act provides for widespread regulation of financial institutions, consumer financial products and services, broker-dealers, over-the-counter derivatives, investment advisers, credit rating agencies, and mortgage lending, which expands federal oversight in the financial sector and may affect the investment management industry as a whole. Given the broad scope, sweeping nature, and the fact that many provisions of the Dodd-Frank Act must be implemented through future rulemaking, the ultimate impact of the Dodd-Frank Act, and any resulting regulation, is not yet certain. As a result, there can be no assurance that these government and regulatory measures will not have an adverse effect on the value or marketability of securities held by a Fund, including potentially limiting or completely restricting the ability of the Fund to use a particular investment instrument as part of its investment strategy, increasing the costs of using these instruments, or possibly making them less effective in general. Furthermore, no assurance can be made that the U.S. Government or any U.S. regulatory entity (or other authority or regulatory entity) will not continue to take further legislative or regulatory action in response to the economic crisis or otherwise, and the effect of such actions, if taken, cannot be known.

148 | MARCH 31, 2012

Certain areas of the world have historically been prone to and economically sensitive to environmental events such as, but not limited to, hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, tornadoes, mudslides, or other weather-related phenomena. Such disasters, and the resulting physical or economic damage, could have a severe and negative impact on a Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses as they would under normal conditions. Adverse weather conditions may also have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

Counterparties

Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The extent of a Fund’s exposure to counterparty risk in respect to financial assets approximates their carrying value as recorded on the Fund’s Statement of Assets and Liabilities.

A Fund may be exposed to counterparty risk through participation in various programs including, but not limited to, lending its securities to third parties, cash sweep arrangements whereby a Fund’s cash balance is invested in one or more types of cash management vehicles, as well as investments in, but not limited to, repurchase agreements, debt securities, and derivatives, including various types of swaps, futures and options. A Fund intends to enter into financial transactions with counterparties that Janus Capital believes to be creditworthy at the time of the transaction. There is always the risk that Janus Capital’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Emerging Market Investing

Investing in emerging markets may involve certain risks and considerations not typically associated with investing in the United States and imposes risks greater than, or in addition to, the risks associated with investing in securities of more developed foreign countries. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Funds’ investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Funds’ investments. To the extent that a Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.

Exchange-Traded Funds

The Funds may invest in exchange-traded funds which generally are index-based investment companies that hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Exchange-Traded Notes

The Funds may invest directly in exchange-traded notes (“ETNs”), which are senior, unsecured, unsubordinated debt securities whose returns are linked to a particular index and provide exposure to the total returns of various market indices, including indices linked to stocks, bonds, commodities and currencies. This type of debt security differs from other types of bonds and notes. ETN returns are based upon the performance of a market index minus applicable fees; no periodic coupon payments are distributed and no principal protections exist. ETNs do not pay cash distributions. Instead, the value of dividends, interest, and investment gains are captured in a Fund’s total return. The Funds may invest in these securities when desiring exposure to debt securities or commodities. When evaluating ETNs for investment, Janus Capital will consider the potential risks involved, expected tax efficiency, rate of return, and credit risk. When the Funds invest in ETNs, they will bear their proportionate share of any fees and expenses borne by the ETN. There may be restrictions on the Funds’ right to redeem their investment in an ETN, which is meant to be held until maturity. The Funds’ decision to sell their ETN holdings may be limited by the availability of a secondary market.

Janus Global & International Funds | 149

Notes to Financial Statements (unaudited) (continued)

Initial Public Offerings

The Funds may invest in initial public offerings (“IPOs”). IPOs and other investment techniques may have a magnified performance impact on a Fund with a small asset base. The Funds may not experience similar performance as their assets grow.

Interfund Lending

As permitted by the Securities and Exchange Commission (“SEC”), or the 1940 Act and rules promulgated thereunder, the Funds may be party to interfund lending agreements between the Funds and other Janus Capital sponsored mutual funds and certain pooled investment vehicles, which permit them to borrow or lend cash at a rate beneficial to both the borrowing and lending funds. Outstanding borrowings from all sources totaling 10% or more of a borrowing Fund’s total assets must be collateralized at 102% of the outstanding principal value of the loan; loans of less than 10% may be unsecured.

Real Estate Investing

The Funds may invest in equity and debt securities of U.S. and non-U.S. real estate-related companies. Such companies may include those in the real estate industry or real estate-related industries. These securities may include common stocks, preferred stocks, and other equity securities, including, but not limited to, REITs and similar REIT-like entities such as foreign entities that have REIT characteristics.

Restricted Security Transactions

Restricted securities held by the Funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933, as amended. The risk of investing in such securities is generally greater than the risk of investing in the securities of widely held, publicly traded companies. Lack of a secondary market and resale restrictions may result in the inability of the Funds to sell a security at a fair price and may substantially delay the sale of the security. In addition, these securities may exhibit greater price volatility than securities for which secondary markets exist.

Securities Lending

Under procedures adopted by the Trustees, the Funds may seek to earn additional income through lending their securities to certain qualified broker-dealers and institutions on a short-term or long-term basis. The Funds may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to 1/3 of their total assets as determined at the time of the loan origination. When the Funds lend their securities, they receive collateral (including cash collateral), at least equal to the value of securities loaned. The Funds may earn income by investing this collateral in one or more affiliated or nonaffiliated cash management vehicles. It is also possible that, due to a decline in the value of a cash management vehicle, the Funds may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Funds may experience delays and costs in recovering the security or gaining access to the collateral provided to the Funds to collateralize the loan. If the Funds are unable to recover a security on loan, the Funds may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Funds. Janus Capital intends to manage the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

The borrower pays fees at the Funds’ direction to Deutsche Bank AG (the “Lending Agent”). The Lending Agent may retain a portion of the interest earned on the cash collateral invested. The cash collateral invested by the Lending Agent is disclosed on the Schedules of Investments (if applicable). The lending fees and the Funds’ portion of the interest income earned on cash collateral are included on the Statements of Operations (if applicable).

The Funds did not have any securities on loan during the period ended March 31, 2012.

Short Sales

The Funds may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into short sales against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

The Funds may also engage in other short sales. The Funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the Funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the

150 | MARCH 31, 2012

lender. No more than 10% of a Fund’s net assets may be invested in short positions (through short sales of stocks, structured products, futures, swaps, and uncovered written calls). The Funds may engage in short sales “against the box” and options for hedging purposes that are not subject to this 10% limit. Although the potential for gain as a result of a short sale is limited to the price at which the Fund sold the security short less the cost of borrowing the security, the potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. There is no assurance the Funds will be able to close out a short position at a particular time or at an acceptable price. A gain or a loss will be recognized upon termination of a short sale. Short sales held by the Funds are fully collateralized by restricted cash or other securities, which are denoted on the accompanying Schedules of Investments (if applicable). The Funds are also required to pay the lender of the security any dividends or interest that accrue on a borrowed security during the period of the loan. Depending on the arrangements made with the broker or custodian, a Fund may or may not receive any payments (including interest) on collateral it has deposited with the broker. The Funds pay stock loan fees, disclosed on the Statements of Operations (if applicable), on assets borrowed from the security broker.

The Funds may also enter into short positions through derivative instruments, such as options contracts, futures contracts, and swap agreements, which may expose the Funds to similar risks. To the extent that the Funds enter into short derivative positions, the Funds may be exposed to risks similar to those associated with short sales, including the risk that the Funds’ losses are theoretically unlimited.

4.  Investment Advisory Agreements and Other Transactions with Affiliates

Each Fund pays Janus Capital an investment advisory fee which is calculated daily and paid monthly. The following table reflects each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate).

			Contractual
			Investment
	Average		Advisory
	Daily		Fee/Base
	Net Assets		Fee (%)
Fund	of the Fund		(annual rate)
Janus Asia Equity Fund		N/A		0.92
Janus Emerging Markets Fund		N/A		1.00
Janus Global Life Sciences Fund		All Asset Levels		0.64
Janus Global Research Fund		N/A		0.64
Janus Global Select Fund		All Asset Levels		0.64
Janus Global Technology Fund		All Asset Levels		0.64
Janus International Equity Fund		N/A		0.68
Janus Overseas Fund		N/A		0.64
Janus Worldwide Fund		N/A		0.60

For Janus Asia Equity Fund, Janus Emerging Markets Fund, Janus Global Research Fund, Janus International Equity Fund, Janus Overseas Fund and Janus Worldwide Fund, the investment advisory fee rate is determined by calculating a base fee and applying a performance adjustment. The base fee rate is the same as the contractual investment advisory fee rate shown in the table above. The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index, as shown below:

Fund	Benchmark Index
Janus Asia Equity Fund		MSCI All Country Asia
		ex-Japan Index
Janus Emerging Markets Fund		MSCI Emerging Markets IndexSM
Janus Global Research Fund		MSCI World Growth Index
Janus International Equity Fund		MSCI EAFE® Index
Janus Overseas Fund		MSCI All Country World
		ex-U.S. IndexSM
Janus Worldwide Fund		MSCI World IndexSM

The calculation of the performance adjustment applies as follows:

Investment Advisory Fee = Base Fee Rate +/- Performance Adjustment

The investment advisory fee rate paid to Janus Capital by each of the Funds listed above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets during the applicable performance measurement period. The performance measurement period generally is the previous 36 months, although no Performance Adjustment is made until a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund). When a Fund’s performance-based fee structure has been in effect for at least 12 months (15 months for Janus Overseas Fund), but

Janus Global & International Funds | 151

Notes to Financial Statements (unaudited) (continued)

less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. Any applicable Performance Adjustments began January 2007 for Janus Global Research Fund, February 2007 for Janus Worldwide Fund, December 2007 for Janus International Equity Fund, November 2011 for Janus Overseas Fund, and January 2012 for Janus Emerging Markets Fund, and will begin August 2012 for Janus Asia Equity Fund.

No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which a Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease Janus Capital’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses, whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, Janus Capital would reimburse the applicable Fund.

The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital may, under some circumstances, exceed the cumulative dollar amount of management fees waived by Janus Capital.

The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. For performance measurement periods prior to July 6, 2009, certain Funds calculated their Performance Adjustment by comparing the performance of Class T Shares (formerly named Class J Shares) against the investment record of its benchmark index. For periods beginning July 6, 2009, the investment performance of a Fund’s load-waived Class A Shares for the performance measurement period is used to calculate the Performance Adjustment. Because the Performance Adjustment is based on a rolling 36-month performance measurement period, calculations based solely on the performance of a Fund’s load-waived Class A Shares will not be fully implemented for 36 months after July 6, 2009. Until that time, the Fund’s performance will be compared to a blended investment performance record that includes the Fund’s Class T Shares (formerly named Class J Shares) performance (the prior share class used for performance calculations) for the portion of the performance measurement period prior to July 6, 2009, and the Fund’s load-waived Class A Shares for the remainder of the period. At the conclusion of the transition period, the Fund’s Class T Shares will be eliminated from the Performance Adjustment calculation, and the calculation will be based solely upon a Fund’s load-waived Class A Shares. After Janus Capital determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares, or Class T Shares (formerly named Class J Shares) as the case may be, against the cumulative investment record of the Fund’s benchmark index, Janus Capital applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable.

It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.

The Funds’ prospectuses and statement of additional information contain additional information about performance-based fees. The amount shown as advisory fees on the Statements of Operations reflects the Base Fee Rate plus/minus any Performance Adjustment, if applicable.

152 | MARCH 31, 2012

During the period ended March 31, 2012, the following Funds recorded a Performance Adjustment as indicated in the table below:

	Performance
Fund	Adjustment
Janus Emerging Markets Fund	$	(4,598)
Janus Global Research Fund		169,593
Janus International Equity Fund		152,401
Janus Overseas Fund		(7,788,012)

Janus Services LLC (“Janus Services”), a wholly-owned subsidiary of Janus Capital, is the Funds’ transfer agent. In addition, Janus Services provides or arranges for the provision of certain other administrative services including, but not limited to, recordkeeping, accounting, order processing, and other shareholder services for the Funds.

Certain, but not all, intermediaries may charge administrative fees to investors in Class A Shares, Class C Shares, and Class I Shares for administrative services provided on behalf of such investors. These administrative fees are paid by the Class A Shares, Class C Shares, and Class I Shares of the Funds to Janus Services, which uses such fees to reimburse intermediaries. Consistent with the Transfer Agency Agreement between Janus Services and the Funds, Janus Services may negotiate the level, structure, and/or terms of the administrative fees with intermediaries requiring such fees on behalf of the Funds. Janus Capital and its affiliates benefit from an increase in assets that may result from such relationships.

Class D Shares pay an annual administrative services fee of 0.12% of net assets. These administrative services fees are paid by the Shares of each Fund for shareholder services provided by Janus Services.

Janus Services receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class R Shares, Class S Shares and Class T Shares of the Funds for providing or procuring administrative services to investors in Class R Shares, Class S Shares and Class T Shares of the Funds. Janus Services expects to use all or a significant portion of this fee to compensate retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries for providing these services. Janus Services or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to Class R Shares, Class S Shares and Class T Shares of each Fund.

Services provided by these financial intermediaries may include, but are not limited to, recordkeeping, subaccounting, order processing, providing order confirmations, periodic statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, answering inquiries regarding accounts, and other administrative services. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with Janus Capital.

Janus Services is compensated for its services related to Class D Shares, and receives reimbursement for its out-of-pocket costs on all other share classes. Included in out-of-pocket expenses are the expenses Janus Services incurs for serving as transfer agent and providing servicing to shareholders.

Janus Distributors LLC (“Janus Distributors”), a wholly-owned subsidiary of Janus Capital, is the distributor of the Funds. The Funds have adopted a Distribution and Shareholder Servicing Plan (the “Plan”) pursuant to Rule 12b-1 under the 1940 Act. The Plan authorizes payments by the Funds at an annual rate, as determined from time to time by the Board of Trustees, of up to 0.25% of the Class A Shares average daily net assets, of up to 1.00% of the Class C Shares average daily net assets, of up to 0.50% of the Class R Shares average daily net assets, and of up to 0.25% of the Class S Shares average daily net assets. Payments under the Plan are not tied exclusively to actual distribution and shareholder service expenses, and the payments may exceed distribution and shareholder service expenses actually incurred by the Funds. If any of a Fund’s actual distribution and shareholder service expenses incurred during a calendar year are less than the payments made during a calendar year, the Fund will be refunded the difference. Refunds, if any, are included in “Distribution fees and shareholder servicing fees” in the Statements of Operations.

Janus Capital has agreed to reimburse certain Funds until at least February 1, 2013 by the amount, if any, that such Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding any performance adjustments to management fees, if applicable, class-specific distribution and shareholder servicing fees applicable to Class A Shares, Class C Shares, Class R Shares, and Class S Shares, the administrative services fees payable pursuant to the Transfer Agency Agreement (except for networking and omnibus fees), brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses, exceed the annual rates noted below. If applicable, amounts reimbursed to the Funds by Janus Capital are disclosed as “Excess Expense Reimbursement” on the Statements of Operations.

The Board of Trustees has adopted a deferred compensation plan (the “Deferred Plan”) for independent Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Funds. All deferred fees are credited to an account established in the name of the Trustees. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the Janus funds that are selected by the Trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of March 31, 2012 on the Statements of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statements of Assets and Liabilities. Deferred compensation expenses for the period ended March 31, 2012 are included in “Non-interested Trustees’ fees and expenses” on the Statements of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were distributed to any Trustee under the Deferred Plan during the period ended March 31, 2012.

For the period ended March 31, 2012, Janus Capital assumed $15,422 of legal, consulting and Trustee costs and fees incurred by the funds in the Trust and Janus Aspen Series together with the Trust (the “Portfolios”), in connection with regulatory and civil litigation matters. These non-recurring costs were allocated to all Portfolios based on the Portfolios’ respective net assets as of July 31, 2004. Unless noted otherwise in the financial highlights, the effect of these non-recurring costs assumed by Janus Capital are included in the ratio of gross expenses to average net assets and were less than 0.01%. No fees were allocated to the Portfolios that commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to the Portfolios based on the Portfolios’ respective net assets on July 31, 2004. These “Non-recurring costs” and “Costs assumed by Janus Capital” are shown on the Statements of Operations.

Certain officers of the Funds may also be officers and/or directors of Janus Capital. Such officers receive no compensation from the Funds, except for the Funds’ Chief Compliance Officer. The Funds reimburse Janus Capital for a portion of the compensation paid to the Chief Compliance Officer and certain compliance staff of the Trust. Total compensation of $531,031 was paid by the Trust during the period ended March 31, 2012. Each Fund’s portion is reported as part of “Other Expenses” on the Statements of Operations.

Class A Shares include a 5.75% upfront sales charge of the offering price of the Funds. The sales charge is allocated between Janus Distributors and financial intermediaries. During the period ended March 31, 2012, Janus Distributors retained the following upfront sales charges:

	Upfront
Fund (Class A Shares)	Sales Charge
Janus Asia Equity Fund	$	495
Janus Emerging Markets Fund		159
Janus Global Life Sciences Fund		787
Janus Global Research Fund		1,878
Janus Global Select Fund		455
Janus Global Technology Fund		227
Janus International Equity Fund		2,346
Janus Overseas Fund		11,375
Janus Worldwide Fund		202

A contingent deferred sales charge (“CDSC”) of 1.00% will be deducted with respect to Class A Shares purchased without a sales load and redeemed within 12 months of purchase, unless waived, as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class A Shares redeemed. During the period ended March 31, 2012, redeeming shareholders of Class A Shares paid the following CDSCs to Janus Distributors:

Fund (Class A Shares)	CDSC
Janus Global Select Fund	$	175
Janus International Equity Fund		5
Janus Overseas Fund		5,600

Class C Shares include a 1.00% CDSC paid by redeeming shareholders to Janus Distributors. The CDSC applies to shares redeemed within 12 months of purchase. The redemption price may differ from the net asset value per share. During the period ended March 31,

Janus Global Research Fund	$	609
Janus Global Select Fund		1,004
Janus Global Technology Fund		143
Janus International Equity Fund		870
Janus Overseas Fund		5,343

During the period, a 2.00% redemption fee was imposed on Class D Shares, Class I Shares, Class R Shares, Class S Shares, and Class T Shares of the Funds, as applicable, held for 90 days or less. This fee was paid to the Funds rather than Janus Capital, and was designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Funds’ asset levels and cash flow due to short-term money movements in and out of the Funds. The redemption fee was accounted for as an addition to Paid-in Capital.

Total redemption fees received by the Funds for the period ended March 31, 2012 are indicated in the table below:

Fund	Redemption Fee
Janus Asia Equity Fund	$	1,246
Janus Emerging Markets Fund		3,496
Janus Global Life Sciences Fund		12,109
Janus Global Research Fund		9,870
Janus Global Select Fund		22,731
Janus Global Technology Fund		28,144
Janus International Equity Fund		5,537
Janus Overseas Fund		366,364
Janus Worldwide Fund		13,671

The Funds’ expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such credits or offsets are included in “Expense and Fee Offset” on the Statements of Operations (if applicable). The transfer agent fee offsets received during the period reduce “Transfer agent fees and expenses” on the Statements of Operations (if applicable). Custodian offsets received reduce “Custodian fees” on the Statements of Operations (if applicable). The Funds could have employed the assets used by the custodian and/or transfer agent to produce income if they had not entered into an expense offset arrangement.

Pursuant to the provisions of the 1940 Act and rules promulgated thereunder, the Funds may participate in an affiliated or nonaffiliated cash sweep program. In the cash sweep program, uninvested cash balances of the Funds may be used to purchase shares of affiliated or nonaffiliated money market funds or cash management pooled investment vehicles. The Funds are eligible to participate in the cash sweep program (the “Investing Funds”). Janus Cash Liquidity Fund LLC is an affiliated unregistered cash management pooled investment vehicle that invests primarily in highly-rated short-term fixed-income securities. Janus Cash Liquidity Fund LLC currently maintains a NAV of $1.00 per share and distributes income daily in a manner consistent with a registered 2a-7 product. There are no restrictions on the Funds’ ability to withdraw investments from Janus Cash Liquidity Fund LLC at will, and there are no unfunded capital commitments due from the Funds to Janus Cash Liquidity Fund LLC. As adviser, Janus Capital has an inherent conflict of interest because of its fiduciary duties to the affiliated cash management pooled investment vehicles and the Investing Funds.

During the six-month period ended March 31, 2012, Janus International Equity Fund received non-recurring income of $24,135 from an affiliated party.

5.  Federal Income Tax

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses, if applicable. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

156 | MARCH 31, 2012

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of March 31, 2012 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/(depreciation) on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments is wash sale loss deferrals, partnerships and passive foreign investment companies.

Accumulated capital losses noted below represent net capital loss carryovers, as of September 30, 2011, that may be available to offset future realized capital gains and thereby reduce future taxable gains distributions. Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Funds will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Losses incurred during those future years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may more likely expire unused. Also, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. The following table shows the expiration dates of the carryovers.

APPROVAL OF ADVISORY AGREEMENTS DURING THE PERIOD

The Trustees of Janus Investment Fund, none of whom has ever been affiliated with Janus Capital and each of whom serves as an “independent” Trustee (the “Trustees”), oversee the management of each Fund and, as required by law, determine annually whether to continue the investment advisory agreement for each Fund and the subadvisory agreements for the nine Funds that utilize subadvisers.

In connection with their most recent consideration of those agreements for each Fund, the Trustees received and reviewed a substantial amount of information provided by Janus Capital and the respective subadvisers in response to requests of the Trustees and their independent legal counsel. They also received and reviewed a considerable amount of information and analysis provided by, and at the request of, their independent fee consultant. Throughout their consideration of the agreements, the Trustees were advised by their independent legal counsel. The Trustees met with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 8, 2011, based on the Trustees’ evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, were fair and reasonable in light of the nature, extent and quality of the services provided by Janus Capital, its affiliates and the subadvisers, the fees charged for those services, and other matters that the Trustees considered relevant in the exercise of their business judgment. At that meeting, the Trustees unanimously approved the continuation of the investment advisory agreement for each Fund, and the subadvisory agreement for each subadvised Fund, for the period from February 1, 2012 through February 1, 2013, subject to earlier termination as provided for in each agreement.

In considering the continuation of those agreements, the Trustees reviewed and analyzed various factors that they determined were relevant, including the factors described below, none of which by itself was considered dispositive. However, the material factors and conclusions that formed the basis for the Trustees’ determination to approve the continuation of the agreements are discussed separately below.

Nature, Extent and Quality of Services

The Trustees reviewed the nature, extent and quality of the services provided by Janus Capital and the subadvisers to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge the Trustees gained from their regular meetings with management on at least a quarterly basis and their ongoing review of information related to the Funds. In addition, the Trustees reviewed the resources and key personnel of Janus Capital and each subadviser, particularly noting those employees who provide investment and risk management services to the Funds. The Trustees also considered other services provided to the Funds by Janus Capital or the subadvisers, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions. The Trustees considered Janus Capital’s role as administrator to the Funds, noting that Janus Capital does not receive a fee for its services but is reimbursed for its out-of-pocket costs. The Trustees considered the role of Janus Capital in monitoring adherence to the Funds’ investment restrictions, providing support services for the Trustees and Trustee committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various policies and procedures of the Funds and with applicable securities laws and regulations.

Additional Information (unaudited) (continued)

The Trustees concluded that the nature, extent and quality of the services provided by Janus Capital or the subadviser to each Fund were appropriate and consistent with the terms of the respective advisory and subadvisory agreements, and that, taking into account steps taken to address those Funds whose performance lagged that of their peers for certain periods, the quality of those services had been consistent with or superior to quality norms in the industry and the Funds were likely to benefit from the continued provision of those services. They also concluded that Janus Capital and each subadviser had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract well-qualified personnel.

Performance of the Funds

The Trustees considered the performance results of each Fund over various time periods. They reviewed information comparing each Fund’s performance with the performance of comparable funds and peer groups identified by Lipper, and with the Fund’s benchmark index. They concluded that the performance of various Funds was good to very good under current market conditions. Although the performance of other Funds lagged that of their peers for certain periods, the Trustees also concluded that Janus Capital had taken or was taking appropriate steps to address those instances of under-performance.

Costs of Services Provided

The Trustees examined information regarding the fees and expenses of each Fund in comparison to similar information for other comparable funds as provided by Lipper. They also reviewed an analysis of that information provided by their independent fee consultant and noted that the rate of management (investment advisory and any administration) fees for most of the Funds, after applicable contractual expense limitations, was below the mean management fee rate of the respective peer group of funds selected by Lipper.

The Trustees considered the methodology used by Janus Capital and each subadviser in determining compensation payable to portfolio managers, the competitive environment for investment management talent and the competitive market for mutual funds in different distribution channels. They concluded that the compensation methodology provided a good alignment of the interests of the portfolio managers with the interests of Fund shareholders.

The Trustees also reviewed management fees charged by Janus Capital and each subadviser to their separate account clients and to non-affiliated funds subadvised by Janus Capital or by a subadviser (for which Janus Capital provides only portfolio management services). Although in most instances subadvisory and separate account fee rates for various investment strategies were lower than management fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of the management agreements with the Funds, Janus Capital performs significant additional services for the Funds that it does not provide to those other clients, including administration services, oversight of the Funds’ other service providers, trustee support, regulatory compliance and numerous other services, and that, in serving the Funds, Janus Capital assumes many legal risks that it does not assume in servicing its other clients. Moreover, they noted that the spread between the average fee rates charged to the Funds and the fee rates that Janus Capital charged to its separate account clients was smaller than the average spread for such fee rates of other advisers, based on publicly available data and research conducted by the Trustees’ independent fee consultant.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. The Trustees also reviewed the financial statements and corporate structure of Janus Capital’s parent company. In their review, the Trustees considered whether Janus Capital and each subadviser receive adequate incentives to manage the Funds effectively. The Trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and the profitability of any fund manager is affected by numerous factors, including the organizational structure of the particular fund manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the fund manager’s capital structure and cost of capital. However, taking into account those factors and the analysis provided by the Trustees’ independent fee consultant, and based on the information available, the Trustees concluded that Janus Capital’s profitability with respect to each Fund in relation to the services rendered was not unreasonable.

The Trustees concluded that the management fees and other compensation payable by each Fund to Janus Capital and its affiliates, as well as the fees paid by Janus Capital to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent and quality of the services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies, the fees Janus Capital and the subadvisers charge to other clients, and, as applicable, the impact of fund performance on fees

164 | MARCH 31, 2012

payable by the Funds. The Trustees also concluded that the overall expense ratio of each Fund was reasonable, taking into account the size of the Fund, the quality of services provided by Janus Capital and any subadviser, the investment performance of the Fund and any expense limitations agreed to by Janus Capital.

Economies of Scale

The Trustees considered information about the potential for Janus Capital to realize economies of scale as the assets of the Funds increase. They noted that, although many Funds pay advisory fees at a fixed rate as a percentage of net assets, without any breakpoints, the actual management fee rate paid by most of the Funds, after any contractual expense limitations, was below the mean management fee rate of the Fund’s peer group identified by Lipper; and, for those Funds whose expenses are being reduced by the contractual expense limitations of Janus Capital, Janus Capital is subsidizing the Funds because they have not reached adequate scale. Moreover, as the assets of many of the Funds have declined in the past few years, certain Funds have benefited from having advisory fee rates that have remained constant rather than increasing as assets declined. In addition, performance fee structures have been implemented for various Funds that have caused or will cause the effective rate of advisory fees payable by such a Fund to vary depending on the investment performance of the Fund relative to its benchmark index over the measurement period; and a few Funds have fee schedules with breakpoints and reduced fee rates above certain asset levels. The Trustees also noted that the Funds share directly in economies of scale through the lower charges of third-party service providers that are based in part on the combined scale of all of the Funds. Based on all of the information they reviewed, including research and analysis conducted by the Trustees’ independent fee consultant, the Trustees concluded that the current fee structure of each Fund was reasonable and that the current rates of fees do reflect a sharing between Janus Capital and the Fund of economies of scale at the current asset level of the Fund.

Other Benefits to Janus Capital

The Trustees also considered benefits that accrue to Janus Capital and its affiliates from their relationships with the Funds. They recognized that two affiliates of Janus Capital separately serve the Funds as transfer agent and distributor, respectively, and the transfer agent receives compensation directly from the non-money market funds for services provided. The Trustees also considered Janus Capital’s past and proposed use of commissions paid by the Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting the Fund and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of these types of client commission arrangements to obtain proprietary and third-party research products and services was consistent with regulatory requirements and guidelines and was likely to benefit each Fund. The Trustees also concluded that, other than the services provided by Janus Capital and its affiliates pursuant to the agreements and the fees to be paid by each Fund therefor, the Funds and Janus Capital may potentially benefit from their relationship with each other in other ways. They concluded that Janus Capital benefits from the receipt of research products and services acquired through commissions paid on portfolio transactions of the Funds and that the Funds benefit from Janus Capital’s receipt of those products and services as well as research products and services acquired through commissions paid by other clients of Janus Capital. They further concluded that success of any Fund could attract other business to Janus Capital or other Janus funds, and that the success of Janus Capital could enhance Janus Capital’s ability to serve the Funds.

After full consideration of the above factors, as well as other factors, the Trustees, each of whom is an independent Trustee, concluded at their December 8, 2011 meeting that the proposed continuation of the investment advisory agreement and, if applicable, the subadvisory agreement for each Fund for another year was in the best interest of the respective Funds and their shareholders.

Explanations of Charts, Tables and
Financial Statements (unaudited)

1.  Performance Overviews

Performance overview graphs compare the performance of a hypothetical $10,000 investment in each Fund (from the ten year period or from the inception date if the period is less than ten years) with one or more widely used market indices. The hypothetical example does not represent the returns of any particular investment.

When comparing the performance of a Fund with an index, keep in mind that market indices do not include brokerage commissions that would be incurred if you purchased the individual securities in the index. They also do not include taxes payable on dividends and interest or operating expenses incurred if you maintained a Fund invested in the index.

Average annual total returns are also quoted for each Fund. Average annual total return is calculated by taking the growth or decline in value of an investment over a period of time, including reinvestment of dividends and distributions, then calculating the annual compounded percentage rate that would have produced the same result had the rate of growth been constant throughout the period. Average annual total return does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or redemptions of Fund shares.

Pursuant to federal securities rules, expense ratios shown in the performance chart reflect subsidized and unsubsidized ratios for the prior fiscal year. The total annual fund operating expenses ratio is gross of any fee waivers, reflecting a Fund’s unsubsidized expense ratio. The net annual fund operating expenses ratio (if applicable) includes contractual waivers of Janus Capital and reflects a Fund’s subsidized expense ratio. Both the total annual fund operating expenses ratio and net annual fund operating expenses ratio are based on average net assets as of the fiscal year ended September 30, 2011 for all Funds except Janus Asia Equity Fund, which is estimated for the fiscal year. The ratios also include expenses indirectly incurred by a Fund as a result of investing in other investment companies or pooled investments, which are not reflected in the “Financial Highlights” of this report. As a result, these ratios may be higher or lower than those shown in the “Financial Highlights” in this report. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

2.  Schedules of Investments

Following the performance overview section is each Fund’s Schedule of Investments. This schedule reports the industry concentrations and types of securities held in each Fund on the last day of the reporting period. Securities are usually listed by type (common stock, corporate bonds, U.S. Government obligations, etc.) and by industry classification (banking, communications, insurance, etc.). Holdings are subject to change without notice.

The value of each security is quoted as of the last day of the reporting period. The value of securities denominated in foreign currencies is converted into U.S. dollars.

If a Fund invests in foreign securities, it will also provide a summary of investments by country. This summary reports each Fund’s exposure to different countries by providing the percentage of securities invested in each country. The country of each security represents the country in which the company is incorporated. Each Fund’s Schedule of Investments relies upon the industry group and country classifications published by Bloomberg L.P.

2a. Forward Currency Contracts

A table listing forward currency contracts follows each Fund’s Schedule of Investments (if applicable). Forward currency contracts are agreements to deliver or receive a preset amount of currency at a future date. Forward currency contracts are used to hedge against foreign currency risk in the Funds’ long-term holdings.

The table provides the name of the foreign currency, the settlement date of the contract, the amount of the contract, the value of the currency in U.S. dollars and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the change in currency exchange rates from the time the contract was opened to the last day of the reporting period.

2b. Futures

A table listing futures contracts follows each Fund’s Schedule of Investments (if applicable). Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. Futures are used to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, the principal amount, value and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the marked-to-market amount for the last day of the reporting period.

2c. Options

A table listing written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options contracts are contracts that obligate a Fund to sell

166 | MARCH 31, 2012

or purchase an underlying security at a fixed price, upon exercise of the option. Options are used to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, exercise price, value and premiums received.

3.  Statements of Assets and Liabilities

These statements are often referred to as the “balance sheets.” They list the assets and liabilities of the Funds on the last day of the reporting period.

The Funds’ assets are calculated by adding the value of the securities owned, the receivable for securities sold but not yet settled, the receivable for dividends declared but not yet received on stocks owned and the receivable for Fund shares sold to investors but not yet settled. The Funds’ liabilities include payables for securities purchased but not yet settled, Fund shares redeemed but not yet paid and expenses owed but not yet paid. Additionally, there may be other assets and liabilities such as unrealized gain or loss on forward currency contracts.

The section entitled “Net Assets Consist of” breaks down the components of the Funds’ net assets. Because the Funds must distribute substantially all earnings, you will notice that a significant portion of net assets is shareholder capital.

The last section of this statement reports the net asset value (“NAV”) per share on the last day of the reporting period. The NAV is calculated by dividing the Funds’ net assets (assets minus liabilities) by the number of shares outstanding.

4.  Statements of Operations

These statements detail the Funds’ income, expenses, gains and losses on securities and currency transactions, and appreciation or depreciation of current Fund holdings.

The first section in this statement, entitled “Investment Income,” reports the dividends earned from stocks and interest earned from interest-bearing securities in the Funds.

The next section reports the expenses incurred by the Funds, including the advisory fee paid to the investment adviser, transfer agent fees and expenses, and printing and postage for mailing statements, financial reports and prospectuses. Expense offsets and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The Funds will realize a gain (or loss) when they sell their position in a particular security. An unrealized gain (or loss) refers to the change in net appreciation or depreciation of the Funds during the reporting period. “Net Realized and Unrealized Gain/(Loss) on Investments” is affected both by changes in the market value of Fund holdings and by gains (or losses) realized during the reporting period.

5.  Statements of Changes in Net Assets

These statements report the increase or decrease in the Funds’ net assets during the reporting period. Changes in the Funds’ net assets are attributable to investment operations, dividends, distributions and capital share transactions. This is important to investors because it shows exactly what caused the Funds’ net asset size to change during the period.

The first section summarizes the information from the Statements of Operations regarding changes in net assets due to the Funds’ investment performance. The Funds’ net assets may also change as a result of dividend and capital gains distributions to investors. If investors receive their dividends in cash, money is taken out of the Funds to pay the distribution. If investors reinvest their dividends, the Funds’ net assets will not be affected. If you compare each Fund’s “Net Decrease from Dividends and Distributions” to the “Reinvested dividends and distributions,” you will notice that dividend distributions had little effect on each Fund’s net assets. This is because the majority of Janus investors reinvest their distributions.

The reinvestment of dividends is included under “Capital Share Transactions.” “Capital Shares” refers to the money investors contribute to the Funds through purchases or withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days or less by a shareholder. The Funds’ net assets will increase and decrease in value as investors purchase and redeem shares from the Funds.

6.  Financial Highlights

This schedule provides a per-share breakdown of the components that affect each Fund’s NAV for current and past reporting periods. Not only does this table provide you with total return, it also reports total distributions, asset size, expense ratios and portfolio turnover rate.

The first line in the table reflects the NAV per share at the beginning of the reporting period. The next line reports the net investment income per share, which comprises dividends and interest income earned on securities held by the Funds. Following is the total of gains/(losses), realized and unrealized. Dividends and distributions are then subtracted to arrive at the NAV per share at the end

Janus Global & International Funds | 167

Explanations of Charts, Tables and
Financial Statements (unaudited) (continued)

of the period. The next line reflects the average annual total return reported the last day of the period. The total return may include adjustments in accordance with generally accepted accounting principles. As a result, the total return may differ from the total return reflected for shareholder transactions.

Also included are the expense ratios, or the percentage of average net assets that were used to cover operating expenses during the period. Expense ratios vary across the Funds within the Trust for a number of reasons, including the differences in management fees, the frequency of dividend payments and the extent of foreign investments, which entail greater transaction costs.

The Funds’ expenses may be reduced through expense-reduction arrangements. These arrangements may include the use of balance credits or transfer agent fee offsets. The Statements of Operations reflect total expenses before any such offset, the amount of the offset and the net expenses. The expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offset (gross expense ratio) and after the expense offsets (net expense ratio). Both expense ratios reflect expenses after waivers (reimbursements), if applicable.

The ratio of net investment income/(loss) summarizes the income earned less expenses, divided by the average net assets of a Fund during the reporting period. Don’t confuse this ratio with a Fund’s yield. The net investment income ratio is not a true measure of a Fund’s yield because it doesn’t take into account the dividends distributed to the Fund’s investors.

The next figure is the portfolio turnover rate, which measures the buying and selling activity in a Fund. Portfolio turnover is affected by market conditions, changes in the asset size of a Fund, fluctuating volume of shareholder purchase and redemption orders, the nature of the Fund’s investments and the investment style and/or outlook of the portfolio manager. A 100% rate implies that an amount equal to the value of the entire portfolio was replaced once during the fiscal year; a 50% rate means that an amount equal to the value of half the portfolio is traded in a year; and a 200% rate means that an amount equal to the value of the entire portfolio is traded every six months.

Janus provides access to a wide range of investment disciplines.

Alternative

Janus alternative funds seek to deliver strong risk-adjusted returns over a full market cycle with lower correlation to equity markets than traditional investments.

Asset Allocation

Janus’ asset allocation funds utilize our fundamental, bottom-up research to balance risk over the long term. From fund options that meet investors’ risk tolerance and objectives to a method that incorporates non-traditional investment choices to seek non-correlated sources of risk and return, Janus’ asset allocation funds aim to allocate risk more effectively.

Fixed Income

Janus fixed income funds attempt to provide less risk relative to equities while seeking to deliver a competitive total return through high current income and appreciation. Janus money market funds seek capital preservation and liquidity with current income as a secondary objective.

Global & International

Janus global and international funds seek to leverage Janus’ research capabilities by taking advantage of inefficiencies in foreign markets, where accurate information and analytical insight are often at a premium.

Growth & Core

Janus growth funds focus on companies believed to be the leaders in their respective industries, with solid management teams, expanding market share, margins and efficiencies. Janus core funds seek investments in more stable and predictable companies. Our core funds look for a strategic combination of steady growth and, for certain funds, some degree of income.

Mathematical

Our mathematical funds seek to outperform their respective indices while maintaining a risk profile equal to or lower than the index itself. Managed by INTECH (a Janus subsidiary), these funds use a mathematical process in an attempt to build a more “efficient” portfolio than the index.

Value

PART C - OTHER INFORMATION

ITEM 15.        Indemnification

          Article VI of Janus Investment Fund’s Amended and Restated Agreement and Declaration of Trust provides for indemnification of certain persons acting on behalf of the Funds. In general, Trustees, officers and Advisory Board members will be indemnified against liability and against all expenses of litigation incurred by them in connection with any claim, action, suit or proceeding (or settlement of the same) in which they become involved by virtue of their connection with the Funds, unless their conduct is determined to constitute willful misfeasance, bad faith, gross negligence or reckless disregard of their duties. A determination that a person covered by the indemnification provisions is entitled to indemnification may be made by the court or other body before which the proceeding is brought, or by either a vote of a majority of a quorum of Trustees who are neither “interested persons” of the Trust nor parties to the proceeding or by an independent legal counsel in a written opinion. The Funds also may advance money for these expenses, provided that the Trustee or officer undertakes to repay the Funds if his or her conduct is later determined to preclude indemnification, and that either he or she provide security for the undertaking, the Trust be insured against losses resulting from lawful advances or a majority of a quorum of disinterested Trustees, or independent counsel in a written opinion, determines that he or she ultimately will be found to be entitled to indemnification. The Trust also maintains a liability insurance policy covering its Trustees, officers and any Advisory Board members.
