COMBINED INFORMATION STATEMENT OF PIONEER GOVERNMENT INCOME FUND AND PROSPECTUS FOR PIONEER BOND FUND (each, a "Pioneer Fund" and together, the "Pioneer Funds") The address and telephone number of each Pioneer Fund is: 60 State Street Boston, Massachusetts 02109 1-800-225-6292 To the Shareholders of Pioneer Government Income Fund: The Board of Trustees of your fund has approved the reorganization of your fund (the "Acquired Fund") with Pioneer Bond Fund (the "Acquiring Fund") after considering the recommendation of Pioneer Investment Management, Inc., the investment manager to your fund and concluding that the reorganization would be in the best interests of your fund. Following is a brief description of certain aspects of the Reorganization: o Your fund and the Acquiring Fund have similar investment objectives and both funds invest primarily in investment grade debt securities. However, the Acquiring Fund may invest in a significantly broader range of debt securities than your fund. Whereas your fund invests at least 80% of its assets in U.S. government securities, the Acquiring Fund invests at least 80% of its assets in investment grade debt securities, including corporate bonds and other debt instruments in addition to U.S. government securities. The Acquiring Fund also may invest up to 20% of its net assets in debt securities rated below investment grade (known as "junk bonds"). Accordingly, as a result of the Reorganization, shareholders of the Acquired Fund, as shareholders of the combined fund, will be exposed to greater investment risk in general, including greater credit exposure, and may experience greater volatility. o The combined fund will pay a lower management fee rate than the management fee rate paid by your fund. o The expense ratio of each class of shares of the combined fund is expected to be lower than the expense ratio of the corresponding class of shares of your fund. o The historical performance of the Acquiring Fund was generally higher than the historical performance of your fund. o Your fund has not achieved a sufficient size to allow for more efficient operations and is not likely to do so in the future. The combined fund may be better positioned to attract assets than your fund. The larger asset size of the combined fund may allow it, relative to your fund, to reduce per share expenses as fixed expenses will be shared over a larger asset base. o The reorganization generally is not expected to have federal income tax consequences for shareholders. The reorganization is expected to occur on or about March 11, 2016. No commission, redemption fee or other transactional fee will be charged as a result of the reorganization. The reorganization does not require shareholder approval, and you are not being asked to vote. We do, however, ask that you review the enclosed information statement/prospectus, which contains information about the Acquiring Fund, outlines the differences between your fund and the Acquiring Fund, and provides details about the terms and conditions of the reorganization. The Board of Trustees of your fund has unanimously approved your fund's reorganization and believes the reorganization is in the best interests of your fund. If you have any questions, please call 1-800-225-6292. Sincerely, Christopher J.

Following the completion of the reorganization, you will be a shareholder in a fund that has the same investment adviser as your fund, similar investment objectives, strategies and policies, and that has management fees that are no higher than your fund's management fees. However, the combined fund will be substantially larger in size. The reorganization does not require shareholder approval, and you are not being asked to vote.

Background to the Reorganization Pioneer Investment Management, Inc. ("Pioneer"), your fund's investment adviser, recommended the reorganization of your fund with the Acquiring Fund (the "Reorganization") for a number of reasons, including: o Your fund and the Acquiring Fund have similar investment objectives to provide current income and both funds invest primarily in investment grade debt securities. However, the Acquiring Fund may invest in a significantly broader range of debt securities than your fund. o The combined fund will pay a lower management fee rate than your fund. The expense ratio of each class of shares of the combined fund is expected to be lower than the expense ratio of the corresponding class of shares of your fund. o The historical performance of the Acquiring Fund was generally higher than the historical performance of your fund. o Your fund has not achieved a sufficient size to allow for more efficient operations and is not likely to do so in the future. The combined fund may be better positioned to attract assets than your fund. The larger asset size of the combined fund may allow it, relative to your fund, to reduce per share expenses as fixed expenses will be shared over a larger asset base. At a meeting held on November 10, 2015, the Board of Trustees of the funds unanimously approved the Reorganization of your fund. The Reorganization of your fund is not subject to approval by the shareholders of your fund. 3 How will the Reorganization work? o The Reorganization is scheduled to occur on or about March 11, 2016, but may occur on such later date as the parties may agree in writing (the "Closing Date"). o Your fund will transfer all of its assets to the Acquiring Fund, and the Acquiring Fund will assume all of the Acquired Fund's liabilities. o The Acquiring Fund will issue Class A, Class C and Class Y shares to your fund in amounts equal to the aggregate net asset value of your fund's Class A, Class C and Class Y shares, respectively. o Shares of the Acquiring Fund will be distributed to you in proportion to the relative net asset value of your holdings of shares of each class of the Acquired Fund on the Closing Date. Therefore, upon completion of the Reorganization, you will hold shares of the corresponding class of the Acquiring Fund with the same aggregate net asset value as your holdings of shares of each class of the Acquired Fund immediately prior to the Reorganization. The net asset value attributable to a class of shares of each fund will be determined using the Pioneer Funds' valuation policies and procedures. Each fund's valuation policy and procedures are identical. o No sales load, contingent deferred sales charge, commission, redemption fee or other transactional fee will be charged as a result of the Reorganization. After the Reorganization, any contingent deferred sales charge that applied to your Class A or Class C shares of the Acquired Fund at the time of the Reorganization will continue to apply for the remainder of the applicable holding period at the time of the Reorganization. In calculating any applicable contingent deferred sales charge, the period during which you held your shares will be included in the holding period of the shares you receive as a result of the Reorganization. o The Reorganization generally is not expected to result in income, gain or loss being recognized for federal income tax purposes by either fund or by the shareholders of either fund. o In approving the Reorganization, the Board of Trustees of each fund, including all of the Trustees who are not "interested" persons (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Pioneer Funds, Pioneer, or Pioneer Funds Distributor, Inc., the Pioneer Funds' principal underwriter and distributor ("PFD") (the "Independent Trustees"), has determined that the Reorganization is in the best interest of each fund and will not dilute the interests of shareholders. The Trustees have made this determination based on factors that are discussed below. In addition to the Class A, Class C and Class Y shares to be issued in the Reorganization, the Acquiring Fund also offers other classes of shares. This Information Statement/Prospectus relates only to the Class A, Class C and Class Y shares to be issued in the Reorganization. What was the basis of the Trustees' determination that the Reorganization was in the best interests of your fund? The Board of Trustees believes that reorganizing your fund with the Acquiring Fund offers you a number of potential benefits. These potential benefits and considerations include: o Your fund and the Acquiring Fund have similar investment objectives (to provide current income) and both funds invest primarily in investment grade debt securities. However, the Acquiring Fund may invest in a significantly broader range of debt securities than your fund, including corporate bonds and other debt instruments in addition to U.S. government securities. The Acquiring Fund also may invest up to 20% of its net assets in debt securities rated below investment grade (known as "junk bonds"). o Your fund has not achieved a sufficient size to allow for more efficient operations and is not likely to do so in the future. The combined fund may be better positioned to attract assets than your fund. The larger asset size of the combined fund may allow it, relative to your fund, to reduce per share expenses as fixed expenses will be shared over a larger asset base. o The expense ratio of each class of shares of the combined fund is expected to be lower than the expense ratio of the corresponding class of shares of your fund. o The combined fund will pay a lower management fee rate than the management fee rate paid by your fund. o The historical performance of the Acquiring Fund was generally higher than the historical performance of your fund. What are the federal income tax consequences of the Reorganization? As a condition to the closing of the Reorganization, the funds must receive an opinion of Morgan, Lewis & Bockius LLP to the effect that the Reorganization will constitute a "reorganization" within the meaning of Section 368(a) of the Code. Accordingly, subject to the limited exceptions described below under the heading "Tax Status of the Reorganization," it is expected that neither you nor your fund will recognize gain or loss as a direct result of the Reorganization, and that the aggregate tax basis of the shares that you receive in the 4 Reorganization will be the same as the aggregate tax basis of the shares that you surrender in the Reorganization. In addition, the holding period of shares you receive in the Reorganization will include the holding period of the shares that you surrender in the Reorganization, provided that you held those shares as capital assets on the date of the Reorganization. However, in accordance with the Pioneer Funds' policy that each Pioneer Fund distributes its investment company taxable income (computed without regard to the dividends-paid deduction), net tax-exempt income and net capital gains for each taxable year (in order to qualify for tax treatment as a regulated investment company and avoid federal income tax thereon at the fund level), your fund will declare and pay a distribution of such income and gains to its shareholders shortly before the Reorganization. Such distribution may affect the amount, timing or character of taxable income that you realize in respect of your fund shares. For more information, see "Tax Status of the Reorganization" on page 32 of the Information Statement/Prospectus. The Pioneer Fund with which the Acquired Fund is being reorganized may make a comparable distribution to its shareholders shortly before the Reorganization. Additionally, following the Reorganization, the Acquiring Fund will continue to make distributions according to its regular distribution schedule. You will generally need to pay tax on those distributions even though they may include income and gains that were accrued and/or realized before you became a shareholder of the Acquiring Fund. Who bears the expenses associated with the Reorganization? Each fund will bear approximately 25% of the expenses incurred in connection with the Reorganization, including expenses associated with the preparation, printing and mailing of any shareholder communications (including this Information Statement/Prospectus), any filings with the SEC and other governmental agencies in connection with the Reorganization, audit fees and legal fees ("Reorganization Costs"). Pioneer will bear the remaining 50% of the Reorganization Costs. It is estimated that these expenses in the aggregate will not exceed $125,000, of which each fund will bear approximately $31,250. 5 REORGANIZATION OF PIONEER GOVERNMENT INCOME FUND WITH PIONEER BOND FUND SUMMARY The following is a summary of more complete information appearing later in this Information Statement/Prospectus or incorporated herein. You should read carefully the entire Information Statement/Prospectus, including the form of Agreement and Plan of Reorganization attached as Exhibit A, because it contains details that are not in the summary. The Board of Trustees of your fund has approved the Reorganization of your fund with the Acquiring Fund. Each fund is managed by Pioneer and has similar investment policies, but there are certain differences between the funds, including: o The investment objectives of your fund and the Acquiring Fund are similar, but not identical. Your fund's investment object is current income. The Acquiring Fund's investment objective is current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. The Acquiring Fund also seeks a relatively stable level of dividends. o Your fund and the Acquiring Fund both invest primarily in investment grade debt securities. However, the Acquiring Fund may invest in a significantly broader range of debt securities than your fund. Your fund invests at least 80% of its assets in U.S. government securities. In contrast, the Acquiring Fund invests at least 80% of its assets in investment grade debt securities, including corporate bonds and other debt instruments in addition to U.S. government securities. The Acquiring Fund also may invest up to 20% of its net assets in debt securities rated below investment grade (known as "junk bonds"). Accordingly, as a result of the Reorganization, the Acquired Fund's shareholders, as shareholders of the combined fund, will be exposed to greater investment risk in general, including greater credit exposure, and may experience greater volatility. The tables below compare certain features of your fund to the features of the Acquiring Fund that will be in effect upon completion of the Reorganization. In the table below, if a row extends across the entire table, the policy disclosed applies to both your fund and the Acquiring Fund. 6 Comparison of Acquired Fund and the Acquiring Fund ----------------------------------------------------------------------------------------------------------------------------- Pioneer Government Income Fund Pioneer Bond Fund (the Acquired Fund) (the Acquiring Fund) ----------------------------------------------------------------------------------------------------------------------------- Investment Current income.

The fund may invest up to 20% of its net assets in grade securities debt securities rated below investment grade or, if ("Junk Bonds") unrated, of equivalent quality as determined by Pioneer (known as "junk bonds"). The fund's investment in debt securities rated below investment grade may include debt securities rated "D" or better, or comparable unrated securities. Debt securities rated "D" are in default. A debt security is below investment grade if it is rated BB or lower by Standard & Poor's Financial Services LLC or the equivalent rating by another nationally recognized statistical rating organization or determined to be of equivalent credit quality by Pioneer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher quality debt securities. Below investment grade securities also may be more difficult to value. ------------------------------------------------------------------------------------------------------------------------------------ Debt Rating For purposes of the fund's credit quality policies, if a security receives different ratings from nationally considerations recognized statistical rating organizations, the fund will use the rating chosen by the portfolio manager as most representative of the security's credit quality. The ratings of nationally recognized statistical rating organizations represent their opinions as to the quality of the securities that they undertake to rate and may not accurately describe the risks of the securities. A rating organization may have a conflict of interest with respect to a security for which it assigns a quality rating. In addition, there may be a delay between a change in the credit quality of a security or other asset and a change in the quality rating assigned to the security or other asset by a rating organization. If a rating organization changes the quality rating assigned to one or more of the fund's securities, Pioneer will consider if any action is appropriate in light of the fund's investment objectives and policies. An investor can still lose significant amounts when investing in investment grade securities. These ratings are used as criteria for the selection of portfolio securities, in addition to Pioneer's own assessment of the credit quality of potential investments. ------------------------------------------------------------------------------------------------------------------------------------ Mortgage-backed The fund may invest in mortgage-backed The fund may invest a substantial portion of its securities securities. assets in mortgage-related securities, including "sub-prime" mortgages, and asset-backed securities. Mortgage-backed securities represent interests in pools of mortgage loans assembled for sale to investors by various U.S. governmental agencies, government-related organizations and private issuers. ------------------------------------------------------------------------------------------------------------------------------------ Mortgage-backed securities may be issued by private issuers, by government-sponsored entities such as the Federal National Mortgage Association ("FNMA") or Federal Home Loan Mortgage Corporation ("FHLMC") or by agencies of the U.S. government, such as the Government National Mortgage Association ("GNMA"). Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property. The fund's investments in mortgage-related securities may include mortgage derivatives and structured securities. The fund may invest in collateralized mortgage obligations (CMOs). A CMO is a mortgage-backed bond that is issued in multiple classes, each with a specified fixed or floating interest rate and a final scheduled distribution date. The holder of an interest in a CMO is entitled to receive specified cash flows from a pool of underlying ------------------------------------------------------------------------------------------------------------------------------------ 10 PRINCIPAL INVESTMENTS ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund (the Acquired Fund) Pioneer Bond Fund (the Acquiring Fund) ------------------------------------------------------------------------------------------------------------------------------------ mortgages or other mortgage-backed securities. Depending upon the class of CMO purchased, the holder may be entitled to payment before the cash flow from the pool is used to pay holders of other classes of the CMO or, alternatively, the holder may be paid only to the extent that there is cash remaining after the cash flow has been used to pay other classes. A subordinated interest may serve as a credit support for the senior securities purchased by other investors. ------------------------------------------------------------------------------------------------------------------------------------ Asset-backed The fund may invest in asset-backed securities. Asset-backed securities represent participations in, or are securities secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables. The fund's investments in asset-backed securities may include derivative and structured securities. ------------------------------------------------------------------------------------------------------------------------------------ The fund may invest in asset-backed securities issued by special entities, such as trusts, that are backed by a pool of financial assets. The fund may invest in collateralized debt obligations (CDOs), which include collateralized bond obligations (CBOs), collateralized loan obligations (CLOs) and other similarly structured securities. A CDO is a trust backed by a pool of fixed income securities. The trust typically is split into two or more portions, called tranches, which vary in credit quality, yield, credit support and right to repayment of principal and interest. Lower tranches pay higher interest rates but represent lower degrees of credit quality and are more sensitive to the rate of defaults in the pool of obligations. Certain CDOs may use derivatives, such as credit default swaps, to create synthetic exposure to assets rather than holding such assets directly. ------------------------------------------------------------------------------------------------------------------------------------ Floating rate The fund may invest in floating rate loans. Floating rate loans are provided by banks and other financial loans institutions to large corporate customers in connection with recapitalizations, acquisitions, and refinancings. These loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These loans are rated below investment grade, but typically are secured with specific collateral and have a senior position in the capital structure of the borrower. These loans typically have rates of interest that are reset periodically by reference to a base lending rate, such as the London Interbank Offered Rate (LIBOR), plus a premium. ------------------------------------------------------------------------------------------------------------------------------------ Subordinated The fund may invest in securities that are subordinated or "junior" to more senior securities of the issuer. The securities investor in a subordinated security of an issuer is entitled to payment after other holders of debt in that issuer. ------------------------------------------------------------------------------------------------------------------------------------ Non-U.S. No stated policy. The fund is permitted to invest in The fund may invest up to 15% of its total assets in investments non-U.S. investments subject to its policy to invest securities of non-U.S. issuers. Up to 5% of the fund's at least 80% of its assets in U.S. government total assets may be invested in securities of securities. emerging market issuers. Non-U.S. issuers are issuers that are organized and have their principal offices outside of the United States. Non-U.S. securities may be issued by non- U.S. governments, banks or corporations, or private issuers, and certain supranational organizations, such as the World Bank and the European Union. The fund considers emerging market issuers to include issuers organized under the laws of an emerging market country, issuers with a principal office in an emerging market country, issuers that derive at least 50% of their gross revenues or profits from goods or services produced in emerging markets, and emerging market governmental issuers. ------------------------------------------------------------------------------------------------------------------------------------ 11 ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund (the Acquired Fund) Pioneer Bond Fund (the Acquiring Fund) ------------------------------------------------------------------------------------------------------------------------------------ Event-linked No stated policy. The fund is permitted to invest in The fund may invest in "event-linked" bonds, which bonds and other event-linked bonds and other insurance-linked sometimes are referred to as "insurance-linked" or insurance-linked securities subject to its policy to invest at least "catastrophe" bonds. Event-linked bonds are debt securities 80% of its assets in U.S. government securities. obligations for which the return of principal and the payment of interest are contingent on the non- occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude or other event that leads to physical or economic loss. For some event-linked bonds, the trigger event's magnitude may be based on losses to a company or industry, industry indexes or readings of scientific instruments rather than specified actual losses. The fund is entitled to receive principal and interest payments so long as no trigger event occurs of the description and magnitude specified by the instrument. Event-linked bonds may be issued by government agencies, insurance companies, reinsurers, special purpose corporations or other on-shore or off-shore entities. The fund may invest in interests in pooled entities that invest primarily in event-linked bonds. Event-linked bonds are typically rated by at least one nationally recognized statistical rating agency, but also may be unrated. The rating for an event-linked bond primarily reflects the rating agency's calculated probability that a pre-defined trigger event will occur. This rating also assesses the event-linked bond's credit risk and the model used to calculate the probability of a trigger event. In addition to event-linked bonds, the fund may also invest in other insurance-linked securities, including structured reinsurance instruments such as quota share instruments (a form of proportional reinsurance whereby an investor participates in the premiums and losses of a reinsurer's portfolio of catastrophe-oriented policies, sometimes referred to as "reinsurance sidecars") and collateralized reinsurance investments, industry loss warranties, and other insurance- and reinsurance-related securities. Quota share instruments and other structured reinsurance instruments generally will be considered illiquid securities by the fund. ----------------------------------------------------------------------------------------------------------------------------------- Zero coupon No stated policy. The fund is permitted to invest in The fund may invest in zero coupon securities. Zero securities zero coupon securities. coupon securities are debt instruments that do not pay interest during the life of the security but are issued at a discount from the amount the investor will receive when the issuer repays the amount borrowed (the face value). The discount approximates the total amount of interest that would be paid at an assumed interest rate. ----------------------------------------------------------------------------------------------------------------------------------- "When-issued", The fund may purchase and sell securities, including No stated policy. The Acquiring Fund is permitted to delayed delivery, mortgaged-backed securities, on a when-issued, invest in "when-issued", delayed delivery, to be to be announced delayed delivery, to be announced or forward announced and forward commitment transactions. and forward commitment basis. These transactions arise when commitment securities are purchased or sold by the fund with transactions payment and delivery taking place at a fixed future date. The fund will not earn income on these securities until delivered. The fund may engage in these transactions when it believes they would result in a favorable price and yield for the security being purchased or sold. ----------------------------------------------------------------------------------------------------------------------------------- 12 ------------------------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund (the Acquired Fund) Pioneer Bond Fund (the Acquiring Fund) ------------------------------------------------------------------------------------------------------------------------------------ Mortgage dollar The fund may enter into mortgage dollar roll No stated policy. The Acquiring Fund is permitted to roll transactions transactions to earn additional income. In these invest in mortgage dollar roll transactions. transactions, the fund sells a U.S. agency mortgage- backed security and simultaneously agrees to purchase at a future date another U.S. agency mortgage-backed security with the same interest rate and maturity date, but generally backed by a different pool of mortgages. The fund loses the right to receive interest and principal payments in the security it sold. However, the fund benefits from the interest earned on investing the proceeds of the sale and may receive a fee or a lower repurchase price. ------------------------------------------------------------------------------------------------------------------------------------ Derivatives The fund may, but is not required to, use futures and options on securities, indices and currencies, forward foreign currency exchange contracts, swaps and other derivatives. The fund also may enter into credit default swaps, which can be used to acquire or to transfer the credit risk of a security or index of securities without buying or selling the security or securities comprising the relevant index. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. The fund may use derivatives for a variety of purposes, including: o In an attempt to hedge against adverse changes in the market prices of securities, interest rates or currency exchange rates o As a substitute for purchasing or selling securities o To attempt to increase the fund's return as a non-hedging strategy that may be considered speculative o To manage portfolio characteristics (for example, the duration or credit quality of the fund's portfolio) o As a cash flow management technique The fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. ------------------------------------------------------------------------------------------------------------------------------------ Inverse floating The fund may invest in inverse floating rate obligations (a type of derivative instrument). The interest rate on rate obligations inverse floating rate obligations will generally decrease as short-term interest rates increase, and increase as short-term rates decrease. Due to their leveraged structure, the sensitivity of the market value of an inverse floating rate obligation to changes in interest rates is generally greater than a comparable long-term bond issued by the same issuer and with similar credit quality, redemption and maturity provisions. Inverse floating rate obligations may be volatile and involve leverage risk. ------------------------------------------------------------------------------------------------------------------------------------ Repurchase In a repurchase agreement, the fund purchases securities from a broker/dealer or a bank, called the agreements counterparty, upon the agreement of the counterparty to repurchase the securities from the fund at a later date, and at a specified price, which is typically higher than the purchase price paid by the fund. The securities purchased serve as the fund's collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the fund is entitled to sell the securities, but the fund may not be able to sell them for the price at which they were purchased, thus causing a loss. Additionally, if the counterparty becomes insolvent, there is some risk that the fund will not have a right to the securities, or the immediate right to sell the securities. ------------------------------------------------------------------------------------------------------------------------------------ Reverse repurchase The fund may enter into reverse repurchase agreements pursuant to which the fund transfers securities to a agreements and counterparty in return for cash, and the fund agrees to repurchase the securities at a later date and for a borrowing higher price. Reverse repurchase agreements are treated as borrowings by the fund, are a form of leverage and may make the value of an investment in the fund more volatile and increase the risks of investing in the fund. The fund also may borrow money from banks or other lenders for temporary purposes. The fund may borrow up to 33 1/3% of its total assets. Entering into reverse repurchase agreements and other borrowing transactions may cause the fund to liquidate positions when it may not be advantageous to do so in order to satisfy its obligations or meet segregation requirements. ------------------------------------------------------------------------------------------------------------------------------------ Cash management Normally, the fund invests substantially all of its assets to meet its investment objectives. The fund may invest and temporary the remainder of its assets in securities with remaining maturities of less than one year or cash equivalents, or investments may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, the fund may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. The fund may adopt a defensive strategy when the adviser believes securities in which the fund normally invests have special or unusual risks or are less attractive due to adverse market, economic, political or other conditions. During such periods, it may be more difficult for the fund to achieve its investment objective. ------------------------------------------------------------------------------------------------------------------------------------ Short-term trading The fund usually does not trade for short-term profits. The fund will sell an investment, however, even if it has only been held for a short time, if it no longer meets the fund's investment criteria. If the fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. ------------------------------------------------------------------------------------------------------------------------------------ 13 Comparison of Principal Risks The following describe the common risks of investing in the Acquired Fund and the Acquiring Fund. For purposes of this section, "the fund" means the Acquired Fund, the Acquiring Fund, or, where applicable, an underlying fund. You could lose money on your investment in the fund. As with any mutual fund, there is no guarantee that the fund will achieve its objectives. Market risk. The values of securities held by the fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets or adverse investor sentiment. Changes in market conditions may not have the same impact on all types of securities. The values of securities may also fall due to specific conditions that affect a particular sector of the securities market or a particular issuer. In the past several years, financial markets, such as those in the United States, Europe, Asia and elsewhere, have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers have defaulted on, or been forced to restructure, their debts. These conditions may continue, recur, worsen or spread. The U.S. government and the Federal Reserve, as well as certain foreign governments and their central banks, have taken steps to support financial markets, including by keeping interest rates at historically low levels. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. The Federal Reserve recently has reduced its market support activities. Further reduction or withdrawal of Federal Reserve or other U.S. or non-U.S. governmental or central bank support, including interest rate increases, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the fund invests. Policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the fund's investments may be negatively affected. The fund may experience a substantial or complete loss on any individual security or derivative position. Particularly during periods of declining or illiquid markets, the fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, and could cause the remaining shareholders in the fund to lose money. This redemption risk is greater to the extent that the fund has investors with large shareholdings, short investment horizons or unpredictable cash flow needs. Interest rate risk. The market prices of securities may fluctuate significantly when interest rates change. When interest rates rise, the value of fixed income securities and therefore the value of your investment in the fund, generally falls. Interest rates have been historically low, so the fund faces a heightened risk that interest rates may rise. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the fund. A change in interest rates will not have the same impact on all fixed income securities. Generally, the longer the maturity or duration of a fixed income security, the greater the impact of a rise in interest rates on the security's value. For example, if interest rates increase by 1%, the value of a fund's portfolio with a portfolio duration of ten years would be expected to decrease by 10%, all other things being equal. Calculations of duration and maturity may be based on estimates and may not reliably predict a security's price sensitivity to changes in interest rates. Moreover, securities can change in value in response to other factors, such as credit risk. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and foreign interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. When interest rates go down, the income received by the fund, and the fund's yield, may decline. Also, when interest rates decline, investments made by the fund may pay a lower interest rate, which would reduce the income received and distributed by the fund. Certain fixed income securities pay interest at variable or floating rates. Variable rate securities tend to reset at specified intervals, while floating rate securities may reset whenever there is a change in a specified index rate. In most cases, these reset provisions reduce the impact of changes in market interest rates on the value of the security. However, some securities do not track the underlying index directly, but reset based on formulas that may produce a leveraging effect; others may also provide for interest payments that vary inversely with market rates. The market prices of these securities may fluctuate significantly when interest rates change. Yield generated by the fund may decline due to a decrease in market interest rates. Credit risk. If an obligor (such as the issuer itself or a party offering credit enhancement) for a security held by the fund fails to pay, otherwise defaults, is perceived to be less creditworthy, becomes insolvent or files for bankruptcy, a security's credit rating is downgraded or the credit quality or value of an underlying asset declines, the value of your investment could decline. If the fund enters into financial contracts (such as certain derivatives, repurchase agreements, reverse repurchase agreements, and when-issued, delayed delivery and forward commitment transactions), the fund will be subject to the credit risk presented by the 14 counterparty. In addition, the fund may incur expenses in an effort to protect the fund's interests or to enforce its rights. Credit risk is broadly gauged by the credit ratings of the securities in which the fund invests. However, ratings are only the opinions of the companies issuing them and are not guarantees as to quality. Securities rated in the lowest category of investment grade (Baa/BBB) may possess certain speculative characteristics. Prepayment or call risk. Many fixed income securities give the issuer the option to prepay or call the security prior to its maturity date. Issuers often exercise this right when interest rates fall. Accordingly, if the fund holds a fixed income security that can be prepaid or called prior to its maturity date, it will not benefit fully from the increase in value that other fixed income securities generally experience when interest rates fall. Upon prepayment of the security, the fund also would be forced to reinvest the proceeds at then current yields, which would be lower than the yield of the security that was prepaid or called. In addition, if the fund purchases a fixed income security at a premium (at a price that exceeds its stated par or principal value), the fund may lose the amount of the premium paid in the event of prepayment. Extension risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration and reduce the value of the security. To the extent the fund invests significantly in mortgage-related and asset-backed securities, its exposure to extension risks may be greater than if it invested in other fixed income securities. Liquidity risk. Liquidity risk exists when particular investments are impossible or difficult to purchase or sell. Although most of the fund's securities and other investments must be liquid at the time of investment, securities and other investments may become illiquid after purchase by the fund, particularly during periods of market turmoil. Markets may become illiquid when, for instance, there are few, if any, interested buyers and sellers or when dealers are unwilling to make a market for certain securities or when dealer market-making capacity is otherwise reduced, and this is more likely to occur as a result of the reduction of market support activity by the Federal Reserve. A lack of liquidity or other adverse credit market conditions may affect the fund's ability to sell the securities in which it invests or to find and purchase suitable investments. These illiquid investments may also be difficult to value. If the fund is forced to sell or unwind an illiquid investment to meet redemption requests or for other cash needs, the fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities and other investments, the fund, due to limitations on investments in illiquid securities, may be unable to achieve its desired level of exposure to a certain sector. Liquidity risk may be magnified in a rising interest rate environment in which investor redemptions from fixed-income mutual funds may be higher than normal. If an auction fails for an auction rate security, there may be no secondary market for the security and the fund may be forced to hold the security until the security is refinanced by the issuer or a secondary market develops. To the extent the fund holds a material percentage of the outstanding debt securities of an issuer, this practice may impact adversely the liquidity and market value of those investments. Portfolio selection risk. The adviser's judgment about the quality, relative yield, relative value or market trends affecting a particular sector or region, market segment, security or about interest rates generally may prove to be incorrect. U.S. Treasury obligations risk. The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the fund's investments in obligations issued by the U.S. Treasury to decline. U.S. government agency obligations risk. The fund invests in obligations issued by agencies and instrumentalities of the U.S. government. Government-sponsored entities such as Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage Corporation ("FHLMC") and the Federal Home Loan Banks ("FHLBs"), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government. Such debt and mortgage-backed securities are subject to the risk of default on the payment of interest and/or principal, similar to debt of private issuers. Although the U.S. government has provided financial support to FNMA and FHLMC in the past, there can be no assurance that it will support these or other government-sponsored entities in the future. Mortgage-related and asset-backed securities risk. The repayment of certain mortgage-backed and asset-backed securities depends primarily on the cash collections received from the issuer's underlying asset portfolio and, in certain cases, the issuer's ability to issue replacement securities. As a result, there could be losses to the fund in the event of credit or market value deterioration in the issuer's underlying portfolio, mismatches in the timing of the cash flows of the underlying asset interests and the repayment obligations of maturing securities, or the issuer's inability to issue new or replacement securities. Mortgage-backed securities tend to be more sensitive to changes in interest rate than other types of debt securities. These securities are also subject to prepayment and extension risks. Upon the occurrence of certain triggering events or defaults, the fund may become the holder of underlying assets at a time when those assets may be difficult to sell or may be sold only at a loss. In the event of a default, the value of the underlying collateral may be insufficient to pay certain expenses, such as litigation and foreclosure expenses, and inadequate to pay 15 any principal or unpaid interest. Privately issued mortgage-backed and asset-backed securities are not traded on an exchange and may have a limited market. Without an active trading market, these securities may be particularly difficult to value given the complexities in valuing the underlying collateral. Certain mortgage-backed and asset-backed securities may pay principal only at maturity or may represent only the right to receive payments of principal or interest on the underlying obligations, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. Principal only instruments generally increase in value if interest rates decline, but are also subject to the risk of prepayment. Interest only instruments generally increase in value in a rising interest rate environment when fewer of the underlying obligations are prepaid. Interest only instruments could lose their entire value in a declining interest rate environment if the underlying obligations are prepaid. Unlike mortgage-related securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, mortgage-related securities issued by private issuers do not have a government or government-sponsored entity guarantee (but may have other credit enhancement), and may, and frequently do, have less favorable collateral, credit risk or other characteristics. The fund may invest in other mortgage-related securities, including mortgage derivatives and structured securities. These securities typically are not secured by real property. Because these securities have embedded leverage features, small changes in interest or prepayment rates may cause large and sudden price movements. These securities also can become illiquid and difficult to value in volatile or declining markets. Mortgage-backed securities are particularly susceptible to prepayment and extension risks, because prepayments on the underlying mortgages tend to increase when interest rates fall and decrease when interest rates rise. Prepayments may also occur on a scheduled basis or due to foreclosure. When market interest rates increase, mortgage refinancings and prepayments slow, which lengthens the effective duration of these securities. As a result, the negative effect of the interest rate increase on the market value of mortgage-backed securities is usually more pronounced than it is for other types of fixed income securities, potentially increasing the volatility of the fund. Conversely, when market interest rates decline, while the value of mortgage-backed securities may increase, the rates of prepayment of the underlying mortgages tend to increase, which shortens the effective duration of these securities. Mortgage-backed securities are also subject to the risk that the underlying borrowers will be unable to meet their obligations. At times, some of the mortgage-backed securities in which the fund may invest will have higher than market interest rates and therefore will be purchased at a premium above their par value. Prepayments may cause losses on securities purchased at a premium. The value of mortgage-backed and asset-backed securities may be affected by changes in credit quality or value of the mortgage loans or other assets that support the securities. In addition, for mortgage-backed securities, when market conditions result in an increase in the default rates on the underlying mortgages and the foreclosure values of the underlying real estate are below the outstanding amount of the underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be less likely. The fund may invest in CMOs. Principal prepayments on the underlying mortgage loans may cause a CMO to be retired substantially earlier than its stated maturity or final distribution date. If there are defaults on the underlying mortgage loans, the fund will be less likely to receive payments of principal and interest, and will be more likely to suffer a loss. This risk may be increased to the extent the underlying mortgages include sub-prime mortgages. As market conditions change, and particularly during periods of rapid or unanticipated changes in market interest rates, the attractiveness of a CMO class and the ability of the structure to provide the anticipated investment characteristics may be significantly reduced. Such changes can result in volatility in the market value, and in some instances reduced liquidity, of a CMO class. In response to the financial crisis that began in 2008, the Federal Reserve has attempted to keep mortgage rates low by acting as a buyer of mortgage-backed assets. This support has recently ended. As a result, mortgage rates may rise and prices of mortgage-backed securities may fall. To the extent the fund's assets are invested in mortgage-backed securities, returns to fund investors may decline. Asset-backed securities are structured like mortgage-backed securities and are subject to many of the same risks. The ability of an issuer of asset-backed securities to enforce its security interest in the underlying asset or to otherwise recover from the underlying obligor may be limited. Certain asset-backed securities present a heightened level of risk because, in the event of default, the liquidation value of the underlying assets may be inadequate to pay any unpaid principal or interest. Risks of investing in floating rate loans. Floating rate loans and similar investments may be illiquid or less liquid than other investments and difficult to value. The value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer's obligations or may be difficult to liquidate. In the event of a default, the fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. Further, the fund's access to collateral, if any, may be limited by bankruptcy law. No active trading market may exist for many floating rate loans, and many loans are subject 16 to restrictions on resale. Market quotations for these securities may be volatile and/or subject to large spreads between bid and ask prices. Any secondary market may be subject to irregular trading activity and extended trade settlement periods. An economic downturn generally leads to a higher non-payment rate, and a loan may lose significant value before a default occurs. There is less readily available, reliable information about most floating rate loans than is the case for many other types of securities. Normally, Pioneer will seek to avoid receiving material, non-public information about the issuer of a loan either held by, or considered for investment by, the fund, and this decision could adversely affect the fund's investment performance. Loans may not be considered "securities," and purchasers, such as the fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Risks of subordinated securities. A holder of securities that are subordinated or "junior" to more senior securities of an issuer is entitled to payment after holders of more senior securities of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, any loss incurred by the subordinated securities is likely to be proportionately greater, and any recovery of interest or principal may take more time. If there is a default, bankruptcy or liquidation of the issuer, most subordinated securities are paid only if sufficient assets remain after payment of the issuer's non-subordinated securities. As a result, even a perceived decline in creditworthiness of the issuer is likely to have a greater impact on them. Municipal securities risk. The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities, potentially resulting in defaults. Issuers often depend on revenues from those projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. Municipal issuers may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In recent periods, an increasing number of municipal issuers in the United States have defaulted on obligations and commenced insolvency proceedings. Financial difficulties of municipal issuers may continue or get worse. To the extent the fund invests significantly in a single state or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, the fund will be more susceptible to associated risks and developments. Risks of zero coupon bonds, payment in kind, deferred and contingent payment securities. Zero coupon bonds (which do not pay interest until maturity) and payment in kind securities (which pay interest in the form of additional securities) may be more speculative and may fluctuate more in value than securities that pay income periodically and in cash. These securities are more likely to respond to changes in interest rates than interest-bearing securities having similar maturities and credit quality. These securities are more sensitive to the credit quality of the underlying issuer. Payment in kind securities may be difficult to value because their continuing accruals require judgments about the collectability of the deferred payments and the value of any collateral. Deferred interest securities are obligations that generally provide for a period of delay before the regular payment of interest begins and are issued at a significant discount from face value. The interest rate on contingent payment securities is determined by the outcome of an event, such as the performance of a financial index. If the financial index does not increase by a prescribed amount, the fund may receive no interest. Unlike bonds that pay interest throughout the period to maturity, the fund generally will realize no cash until maturity and, if the issuer defaults, the fund may obtain no return at all on its investment. In addition, although the fund receives no periodic cash payments on such securities, the fund is deemed for tax purposes to receive income from such securities, which applicable tax rules require the fund to distribute to shareholders. Such distributions may be taxable when distributed to shareholders and, in addition, could reduce the fund's reserve position and require the fund to sell securities and incur a gain or loss at a time it may not otherwise want in order to provide the cash necessary for these distributions. Risks of investing in "when-issued", delayed delivery, to be announced and forward commitment transactions. The market value of these transactions may increase or decrease as a result of changes in interest rates. These transactions involve risk of loss if the value of the underlying security changes unfavorably before the settlement date or if the assets set aside to pay for these securities decline in value prior to the settlement date. Therefore, these transactions may have a leveraging effect on the fund, making the value of an investment in the fund more volatile and increasing the fund's overall investment exposure. There is also a risk that the security will not be issued or that the other party to the transaction will default on its obligation to purchase or sell the security, which may result in the fund missing the opportunity to obtain a favorable price or yield elsewhere. Derivatives risk. Using swaps, futures and other derivatives exposes the fund to special risks and costs and may result in losses to the fund, even when used for hedging purposes. Using derivatives can increase losses and reduce opportunities for gain when market prices, interest rates or currencies, or the derivative instruments themselves, behave in a way not anticipated by the fund, especially 17 in abnormal market conditions. Using derivatives can have a leveraging effect (which may increase investment losses) and increase the fund's volatility, which is the degree to which the fund's share price may fluctuate within a short time period. Certain derivatives have the potential for unlimited loss, regardless of the size of the fund's initial investment. If changes in a derivative's value do not correspond to changes in the value of the fund's other investments or do not correlate well with the underlying assets, rate or index, the fund may not fully benefit from, or could lose money on, or could experience unusually high expenses as a result of, the derivative position. The other parties to certain derivative transactions present the same types of credit risk as issuers of fixed income securities. Derivatives also tend to involve greater liquidity risk and they may be difficult to value. The fund may be unable to terminate or sell its derivative positions. In fact, many over-the-counter derivatives will not have liquidity beyond the counterparty to the instrument. Use of derivatives or similar instruments may have different tax consequences for the fund than an investment in the underlying security, and those differences may affect the amount, timing and character of income distributed to shareholders. The fund's use of derivatives may also increase the amount of taxes payable by shareholders. Risks associated with the use of derivatives are magnified to the extent that an increased portion of the fund's assets are committed to derivatives in general or are invested in just one or a few types of derivatives. Investments by the fund in structured securities, a type of derivative, raise certain tax, legal, regulatory and accounting issues that may not be presented by direct investments in securities. These issues could be resolved in a manner that could hurt the performance of the fund. Swap agreements and options to enter into swap agreements ("swaptions") tend to shift the fund's investment exposure from one type of investment to another. For example, the fund may enter into interest rate swaps, which involve the exchange of interest payments by the fund with another party, such as the exchange of floating rate payments for fixed interest payments with respect to a notional amount of principal. If an interest rate swap intended to be used as a hedge negates a favorable interest rate movement, the investment performance of the fund would be less than it would have been if the fund had not entered into the interest rate swap. The U.S. government and foreign governments are in the process of adopting and implementing regulations governing derivative markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, may limit their availability or utility or otherwise adversely affect their performance, or may disrupt markets. The fund may be exposed to additional risks as a result of the additional regulations. The extent and impact of the regulations are not yet fully known and may not be for some time. The fund will be required to maintain its positions with a clearing organization through one or more clearing brokers. The clearing organization will require the fund to post margin and the broker may require the fund to post additional margin to secure the fund's obligations. The amount of margin required may change from time to time. In addition, cleared transactions may be more expensive to maintain than over-the-counter transactions and may require the fund to deposit larger amounts of margin. The fund may not be able to recover margin amounts if the broker has financial difficulties. Also, the broker may require the fund to terminate a derivatives position under certain circumstances. This may cause the fund to lose money. The fund's ability to use certain derivative instruments currently is limited by Commodity Futures Trading Commission rules. Risks of investing in inverse floating rate obligations. The interest rate on inverse floating rate obligations will generally decrease as short-term interest rates increase, and increase as short-term rates decrease. Due to their leveraged structure, the sensitivity of the market value of an inverse floating rate obligation to changes in interest rates is generally greater than a comparable long-term bond issued by the same issuer and with similar credit quality, redemption and maturity provisions. Inverse floating rate obligations may be volatile and involve leverage risk. Leveraging risk. The value of your investment may be more volatile and other risks tend to be compounded if the fund borrows or uses derivatives or other investments that have embedded leverage. Leverage generally magnifies the effect of any increase or decrease in the value of the fund's underlying assets and creates a risk of loss of value on a larger pool of assets than the fund would otherwise have, potentially resulting in the loss of all assets. Engaging in such transactions may cause the fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements. Repurchase agreement risk. In the event that the other party to a repurchase agreement defaults on its obligations, the fund may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. In addition, if the fund is characterized by a court as an unsecured creditor, it would be at risk of losing some or all of the principal and interest involved in the transaction. Market segment risk. To the extent the fund emphasizes, from time to time, investments in a market segment, the fund will be subject to a greater degree to the risks particular to that segment, and may experience greater market fluctuation, than a fund without the same focus. For example, industries in the financial segment, such as banks, insurance companies, broker-dealers and real estate investment trusts (REITs), may be sensitive to changes in interest rates and general economic activity and are generally subject to extensive government regulation. 18 Valuation risk. Many factors may influence the price at which the fund could sell any particular portfolio investment. The sales price may well differ -- higher or lower - from the fund's last valuation of the investment, and such differences could be significant, particularly for illiquid securities and securities that trade in thin markets and/or markets that experience extreme volatility. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued the security or had used a different valuation methodology. Fixed income securities are typically valued using fair value methodologies. The value of foreign securities, certain fixed income securities and currencies, as applicable, may be materially affected by events after the close of the market on which they are valued, but before the fund determines its net asset value. Cash management risk. The value of the investments held by the fund for cash management or temporary defensive purposes may be affected by market risks, changing interest rates and by changes in credit ratings of the investments. To the extent that the fund has any uninvested cash, the fund would be subject to credit risk with respect to the depository institution holding the cash. If the fund holds cash uninvested, the fund will not earn income on the cash and the fund's yield will go down. During such periods, it may be more difficult for the fund to achieve its investment objectives. Expense risk. Your actual costs of investing in the fund may be higher than the expenses shown in "Annual fund operating expenses" for a variety of reasons. For example, expense ratios may be higher than those shown if overall net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile. In addition to the common risks of investing in the Acquired Fund and the Acquiring Fund, the following are additional principal risks of investment in the Acquiring Fund: Risks of instruments that allow for balloon payments or negative amortization payments. Certain debt instruments allow for balloon payments or negative amortization payments. Such instruments permit the borrower to avoid paying currently a portion of the interest accruing on the instrument. While these features make the debt instrument more affordable to the borrower in the near term, they increase the risk that the borrower will be unable to make the resulting higher payment or payments that become due at the maturity of the loan. High yield or "junk" bond risk. Debt securities that are below investment grade, called "junk bonds," are speculative, have a higher risk of default or are already in default, tend to be less liquid and are more difficult to value than higher grade securities and may involve major risk of exposure to adverse conditions and negative sentiments. These securities have a higher risk of issuer default because, among other reasons, issuers of junk bonds often have more debt in relation to total capitalization than issuers of investment grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments. These risks are more pronounced for securities that are already in default. Changes in economic conditions or developments regarding the individual issuer are more likely to cause price volatility and weaken the capacity of such securities to make principal and interest payments than is the case for higher grade debt securities. The value of lower-quality debt securities often fluctuates in response to company, political, or economic developments and can decline significantly over short as well as long periods of time or during periods of general or regional economic difficulty. Junk bonds may also be less liquid than higher-rated securities, which means that the fund may have difficulty selling them at times, and it may have to apply a greater degree of judgment in establishing a price for purposes of valuing fund shares. Junk bonds generally are issued by less creditworthy issuers. In the event of an issuer's bankruptcy, claims of other creditors may have priority over the claims of junk bond holders, leaving few or no assets available to repay junk bond holders. The fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer. Junk bonds frequently have redemption features that permit an issuer to repurchase the security from the fund before it matures. If the issuer redeems junk bonds, the fund may have to invest the proceeds in bonds with lower yields and may lose income. Risks of investing in insurance-linked securities. The return of principal and the payment of interest on "event-linked" bonds and other insurance-linked securities are contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude or other event that leads to physical or economic loss. If a trigger event, as defined within the terms of an event-linked bond, involves losses or other metrics exceeding a specific magnitude in the geographic region and time period specified, the fund may lose a portion or all of its accrued interest and/or principal invested in the event-linked bond. In addition to the specified trigger events, event-linked bonds may expose the fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Event-linked bonds are also subject to the risk that the model used to calculate the probability of a trigger event was not accurate and underestimated the likelihood of a trigger event. Insurance-linked securities may provide for extensions of maturity in order to process and audit loss claims in those cases when a trigger event has, or possibly has, occurred. Upon the occurrence or possible occurrence of a trigger event, and until the completion of the processing and auditing of applicable loss claims, the fund's investment in an event-linked bond or other insurance-linked security may be priced using fair value methods. Lack of a liquid market may impose the risk of higher transaction costs and the possibility that the fund may be forced to liquidate positions when it would not be advantageous to do so. Certain 19 insurance-linked securities represent interests in baskets of underlying reinsurance contracts. The fund has limited transparency into the individual contracts underlying such securities and therefore must rely on the risk assessment and sound underwriting practices of the issuer. Certain insurance-linked securities may be difficult to value. Risks of non-U.S. investments. Investing in non-U.S. issuers, or in U.S. issuers that have significant exposure to foreign markets, may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced for issuers in emerging markets or to the extent that the fund invests significantly in one region or country. These risks may include: o Less information about non-U.S. issuers or markets may be available due to less rigorous disclosure or accounting standards or regulatory practices o Many non-U.S. markets are smaller, less liquid and more volatile. In a changing market, the adviser may not be able to sell the fund's portfolio securities at times, in amounts and at prices it considers reasonable o Adverse effect of currency exchange rates or controls on the value of the fund's investments, or its ability to convert non-U.S. currencies to U.S. dollars o The economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession o Economic, political, regulatory and social developments may adversely affect the securities markets o It may be difficult for the fund to pursue claims or enforce judgments against a foreign bank, depository or issuer of a security, or any of their agents, in the courts of a foreign country o Withholding and other non-U.S. taxes may decrease the fund's return. The value of the fund's foreign investments also may be affected by U.S. tax considerations and restrictions in receiving investment proceeds from a foreign country o Some markets in which the fund may invest are located in parts of the world that have historically been prone to natural disasters that could result in a significant adverse impact on the economies of those countries and investments made in those countries o It is often more expensive for the fund to buy, sell and hold securities in certain foreign markets than in the United States o A governmental entity may delay, or refuse or be unable to pay, interest or principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity's debt position in relation to the economy or the failure to put in place economic reforms o Investing in depositary receipts is subject to many of the same risks as investing directly in non-U.S. issuers. Depositary receipts may involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange. o A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the fund's investments in euro-denominated securities and derivative contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries o If one or more stockholders of a supranational entity such as the World Bank fail to make necessary additional capital contributions, the entity may be unable to pay interest or repay principal on its debt securities Risks of convertible securities. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. As with all fixed income securities, the market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security approaches or exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. As the market price of the underlying common stock declines, the convertible security tends to trade increasingly on a yield basis and thus may not decline in price to the same extent as the underlying common stock. Convertible securities rank senior to common stocks in an issuer's capital structure and consequently entail less risk than the issuer's common stock. The value of a synthetic convertible security will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible security is composed of two or more separate securities or instruments, each with its own market value. If the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value. Preferred stocks risk. Preferred stocks may pay fixed or adjustable rates of return. Preferred stocks are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company's preferred stocks generally pay dividends only after the company makes required payments to holders of its bonds and other debt. Thus, the value of preferred stocks will usually react more strongly than bonds and other debt to actual or perceived changes in the company's financial condition or prospects. 20 The market value of preferred stocks generally decreases when interest rates rise. Preferred stocks of smaller companies may be more vulnerable to adverse developments than preferred stocks of larger companies. Credit default swap risk. Credit default swap contracts, a type of derivative instrument, involve heightened risks and may result in losses to the fund. Credit default swaps may in some cases be illiquid and difficult to value, and they increase credit risk since the fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap. If the fund buys a credit default swap, it will be subject to the risk that the credit default swap may expire worthless, as the credit default swap would only generate income in the event of a default on the underlying debt security or other specified event. As a buyer, the fund would also be subject to credit risk relating to the seller's payment of its obligations in the event of a default (or similar event). If the fund sells a credit default swap, it will be exposed to the credit risk of the issuer of the obligation to which the credit default swap relates. As a seller, the fund would also be subject to leverage risk, because it would be liable for the full notional amount of the swap in the event of default (or similar event). Swaps may be difficult to unwind or terminate. Certain index-based credit default swaps are structured in tranches, whereby junior tranches assume greater default risk than senior tranches. The absence of a central exchange or market for swap transactions may lead, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions. New regulations require many kinds of swaps to be executed through a centralized exchange or regulated facility and be cleared through a regulated clearinghouse. Although this clearing mechanism is generally expected to reduce counterparty credit risk, it may disrupt or limit the swap market and may not result in swaps being easier to trade or value. As swaps become more standardized, the fund may not be able to enter into swaps that meet its investment needs. The fund also may not be able to find a clearinghouse willing to accept the swaps for clearing. In a cleared swap, a central clearing organization will be the counterparty to the transaction. The fund will assume the risk that the clearinghouse may be unable to perform its obligations. The new regulations may make using swaps more costly, may limit their availability, or may otherwise adversely affect their value or performance. The following is an additional principal risk of the Acquired Fund; as noted above, the Acquiring Fund is also permitted to invest in mortgage dollar roll transactions: Mortgage dollar roll transactions risk. The benefits to the fund from mortgage dollar roll transactions depend upon the adviser's ability to forecast mortgage prepayment patterns on different mortgage pools. The fund may lose money if, during the period between the time it agrees to the forward purchase of the mortgage securities and the settlement date, these securities decline in value due to market conditions or prepayments on the underlying mortgages. Comparison of Fees and Expenses Shareholders of both Pioneer Funds pay various fees and expenses, either directly or indirectly. The tables below show the fees and expenses that you would pay if you were to buy and hold shares of each Pioneer Fund. The expenses in the tables appearing below are based on (i) for the Acquired Fund, expenses for the twelve-month period ended July 31, 2015, and (ii) for the Acquiring Fund, expenses for the twelve-month period ended June 30, 2015. Future expenses for all share classes may be greater or less. The tables also show the combined fund's pro forma expenses assuming the Reorganization occurred on June 30, 2015.

(2) Pioneer has contractually agreed to limit ordinary operating expenses (ordinary operating expenses means all fund expenses other than extraordinary expenses, such as litigation, taxes, brokerage commissions and acquired fund fees and expenses) to the extent required to reduce fund expenses to 0.85% of the average daily net assets attributable to Class A shares. This expense limitation is in effect through November 1, 2017. There can be no assurance that Pioneer will extend the expense limitation beyond such time. While in effect, the arrangement may be terminated for a class only by agreement of the adviser and the Board of Trustees. Examples: The examples are intended to help you compare the cost of investing in each fund with the cost of investing in other mutual funds. The examples assume that you invest $10,000 in each fund for the time periods shown, and then, except as indicated, redeem all of your shares at the end of those periods. The examples also assume that (a) your investment has a 5% return each year and (b) each fund's total annual operating expenses remain the same except for year one (which considers the effect of the expense limitation). Pro forma expenses are included assuming consummation of the Reorganization as of June 30, 2015. The examples are for comparison purposes only and are not a representation of any fund's actual expenses or returns, either past or future.

The Trustees considered the following matters, among others, in approving the proposal. First, the Board considered the similarities and differences in the funds' investment objectives and principal investment strategies. The Board considered that your fund and the Acquiring Fund have similar investment objectives to provide current income. The Board considered that both funds invest primarily in investment grade debt securities. The Board considered that the Acquiring Fund may invest in a significantly broader range of debt securities than your fund, noting that your fund invests at least 80% of its assets in U.S. government securities, while the Acquiring Fund invests at least 80% of its assets in investment grade debt securities, including corporate bonds and other debt instruments in addition to U.S. government securities. The Board considered that the Acquiring Fund also may invest up to 20% of its net assets in debt securities rated below investment grade (known as "junk bonds"). Second, the Board considered that your fund has not achieved a sufficient size to allow for more efficient operations and is not likely to do so in the future. The Board considered that the combined fund may be better positioned to attract assets than your fund. The Board considered that the larger asset size of the combined fund may allow it, relative to your fund, to reduce per share expenses as fixed expenses will be shared over a larger asset base. Third, the Board considered that the expense ratio of each class of shares of the combined fund is expected to be lower than the expense ratio of the corresponding class of shares of your fund, both before and after any applicable fee waivers or expense reimbursements. Fourth, the Board considered that the combined fund will pay a lower management fee rate than the management fee rate paid by your fund. Fifth, the Board considered that the historical performance of the Acquiring Fund was higher than the historical performance of your fund for the three, five and ten-year periods ended October 2, 2015, based on data provided by Morningstar, Inc. The Board noted that your fund's performance was higher than the performance of the Acquiring Fund for the one-year period ended October 2, 2015. Sixth, the Board considered the ability of the combined fund to utilize certain tax capital-loss carryforwards in the future. Seventh, the Board considered that the Acquired Fund would bear approximately 25% of the expenses incurred in connection with the Reorganization, including expenses associated with the preparation, printing and mailing of any shareholder communications (including this Information Statement/Prospectus), any filings with the SEC and other governmental agencies in connection with the Reorganization, audit fees and legal fees, and the Acquiring Fund would likewise bear approximately 25% of these costs. The Board considered that Pioneer would bear the remaining 50% of the expenses incurred in connection with the Reorganization. In approving the allocation of Reorganization costs, the Board considered information provided by Pioneer with respect to the relative short-term economic benefits and costs to shareholders anticipated to result from the Reorganization. Eighth, the Board considered that the Reorganization generally is not expected to result in income, gain or loss being recognized for federal income tax purposes by your fund, Pioneer Bond Fund or by the shareholders of either fund. Ninth, the Board considered that the funds' investment adviser and principal distributor would benefit from the Reorganization. For example, Pioneer might achieve cost savings from managing one larger fund compared to managing more than one fund with similar investment strategies. The consolidated portfolio management effort also might result in time and personnel savings and the preparation of fewer reports and regulatory filings, as well as prospectus disclosure, for one fund instead of two. The Board believes that the Reorganization, in the long-term, could result in a decrease in the combined fund's gross expenses. Tenth, the Board also considered that the Reorganization presents an excellent opportunity for the shareholders of each fund to become investors in a combined fund that has a larger asset size than either fund alone without the obligation to pay commissions or other transaction costs that a fund normally incurs when purchasing securities. This opportunity provides an economic benefit to both funds and their shareholders. 27 CAPITALIZATION The following table sets forth the capitalization of each Pioneer Fund as of December 18, 2015, and the pro forma combined capitalization of the combined fund as if the Reorganization occurred on that date. The actual exchange ratios on the Closing Date may vary from the exchange ratios indicated. This is due to changes in the market value of the portfolio securities of the Pioneer Funds between December 18, 2015 and the Closing Date, changes in the amount of undistributed net investment income and net realized capital gains of the Pioneer Funds during that period resulting from income and distributions, and changes in the accrued liabilities of the Pioneer Funds during the same period.

The expenses of the Reorganization borne by the funds are estimated in the aggregate to be $62,500. Pioneer will bear the remaining expenses of the Reorganization. It is impossible to predict how many shares of the combined fund will actually be received and distributed by your fund on the Closing Date. The table should not be relied upon to determine the amount of combined fund shares that will actually be received and distributed. BOARDS' EVALUATION OF THE REORGANIZATION For the reasons described above, the Board of Trustees of your fund, including the Independent Trustees, approved the Reorganization. In particular, the Board of Trustees determined that the Reorganization is in the best interests of your fund and that the interests of your fund's shareholders would not be diluted as a result of the Reorganization. Similarly, the Board of Trustees of the Acquiring Fund, including the Independent Trustees, approved the Reorganization. The Trustees also determined that the Reorganization is in the best interests of that fund and that the interests of the shareholders of that fund would not be diluted as a result of the Reorganization. 28 OTHER IMPORTANT INFORMATION CONCERNING THE REORGANIZATION Portfolio Securities After the closing of the Reorganization, management will analyze and evaluate the portfolio securities of the combined fund. Consistent with the combined fund's investment objective and policies, any restrictions imposed by the Code and in the best interests of the shareholders of the combined fund (including former shareholders of your fund), management will influence the extent and duration to which the portfolio securities of your fund and the Acquiring Fund will be maintained by the combined fund. It is possible that, although it is not necessary to dispose of portfolio securities in order to effect the Reorganization, the portfolio manager of the combined fund may conclude that some of the holdings of the combined fund are not consistent with the combined fund's long-term investment strategy, and, accordingly, there may be dispositions of some of the portfolio securities of a combined fund following the Reorganization. Subject to market conditions at the time of any such disposition, the disposition of the portfolio securities by a combined fund may result in a capital gain or loss. The actual tax consequences of any disposition of portfolio securities will vary depending upon the specific security(ies) being sold, other capital gains and losses that may be recognized, and the combined fund's ability to use any available tax loss carryforwards. The disposition of portfolio securities also may result in significant brokerage expense to the combined fund. Tax Capital Loss Carryforwards Federal income tax law permits a regulated investment company to carry forward net capital losses that arose in tax years that began on or before December 22, 2010 ("Pre-2011 Losses") for a period of up to eight taxable years. Net capital losses that arise in tax years beginning after December 22, 2010 ("Post-2010 Losses") may generally be carried forward without limit, and such carryforwards must be fully utilized before the regulated investment company is permitted to utilize carryforwards of Pre-2011 Losses. Presently, the net capital loss carryforwards of Pioneer Government Income Fund and Pioneer Bond Fund from their prior taxable years can be summarized as follows: Fund Capital Loss Carryforward ------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund $9,482,795 ------------------------------------------------------------------------------------------------------------------ Pioneer Bond Fund $ -- ------------------------------------------------------------------------------------------------------------------ The Funds' Pre-2011 Losses and their expiration dates are as follows: Fund 7/31/2016 7/31/2017 7/31/2018 ------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund $2,793,238 $ -- $ -- ------------------------------------------------------------------------------------------------------------------ Fund 6/30/2016 6/30/2017 6/30/2018 ------------------------------------------------------------------------------------------------------------------ Pioneer Bond Fund $ -- $ -- $ -- ------------------------------------------------------------------------------------------------------------------ The Funds' Post-2010 Losses are as follows: Fund Capital Loss Carryforward ------------------------------------------------------------------------------------------------------------------ Pioneer Government Income Fund $6,689,557 (short term capital losses: $844,011 long term capital losses: $5,845,546) ------------------------------------------------------------------------------------------------------------------ Pioneer Bond Fund $ -- ------------------------------------------------------------------------------------------------------------------ For the period ending on the Closing Date, each fund may have net realized capital gains or losses and as of the Closing Date a fund may also have net unrealized capital gains or losses. Your fund's Pre-2011 Losses, to the extent unused, will expire on the earlier of July 31, 2016 and the date on which the Reorganization closes. The Reorganization may result in a number of additional limitations on the combined fund's ability to use realized and unrealized losses of the combining funds. The discussion below describes the limitations that may apply based on the funds' tax attributes and relative net asset values as of October 31, 2015. Since the Reorganization is not expected to close until March 11, 2016, the net current-year realized capital losses and net unrealized capital gains and the effect of the limitations described may change significantly between now and the completion of the Reorganization. Further, the ability of your fund and Pioneer Bond Fund to use capital losses to offset gains (even in the absence of the Reorganization) depends on factors other than loss limitations, such as the future realization of capital gains or losses. 29 First, in the tax year of the combined fund in which the Reorganization occurs, the combined fund will be able to use carryforwards of your fund's capital losses (including from your fund's short taxable year ending on the Closing Date), subject to the limitations described in the following paragraphs, to offset only a prorated portion of the combined fund's capital gains for such tax year, based on the number of days remaining in the combined fund's tax year after the Closing Date. Second, the Reorganization is expected to result in a limitation on the combined fund's ability to use your fund's capital loss carryforwards in subsequent tax years. This limitation, imposed by Section 382 of the Code, is expected to apply because your fund has capital loss carryforwards and its shareholders will own less than 50% of the combined fund immediately after the Reorganization. The annual Section 382 limitation for periods following the Reorganization generally will equal the product of the net asset value of your Fund immediately prior to the Reorganization and the "long-term tax-exempt rate," published by the Internal Revenue Service, in effect at the time of the Reorganization (as of October 31, 2015, the annual limitation would be $2,990,115). Third, the Reorganization may result in a limitation on the combined fund's ability to use a portion of losses recognized by the combined fund in the taxable year in which the Reorganization occurs, or, in certain cases, a net unrealized loss inherent in the assets of Pioneer Bond Fund at the time of the Reorganization, to offset gains realized after the Reorganization that are attributable to unrealized capital gains of your fund as of the Closing Date. That limitation will apply if your fund's unrealized capital gains as of the Closing Date are at least $10,000,000 or at least 15% of the fair market value of your fund's assets as of the Closing Date. Fourth, the Reorganization may result in a limitation on the combined fund's ability to use capital loss carryforwards of your fund (including any net loss from your fund's short taxable year ending on the date of the Reorganization) to offset gains realized after the Reorganization that are attributable to unrealized capital gains in Pioneer Bond Fund's assets immediately prior to the Reorganization. This limitation will generally apply if Pioneer Bond Fund's unrealized capital gains as of the date of the Reorganization are at least $10,000,000 or at least 15% of the fair market value of Pioneer Bond Fund's assets as of the Closing Date. As of October 31, 2015, the funds had the following current-year realized capital gains(losses) and net realized gains: Fund Current-Year Realized Capital Gains(Losses) Net Unrealized Gains -------------------------------------------------------------------------------------------- Pioneer Government Income Fund $79,772 $3,548,104 -------------------------------------------------------------------------------------------- Pioneer Bond Fund ($6,863,722) $7,280,173 Fifth, any capital loss carryforwards from prior years, any net current-year capital losses, and, potentially, any unrealized capital losses will benefit the shareholders of the combined fund, rather than only the shareholders of the combining fund in which the loss originated. 30 TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION The Reorganization o The Reorganization is scheduled to occur as of the close of business on March 11, 2016 but may occur on such later date as the parties may agree to in writing. o The Acquired Fund will transfer all of its assets to the Acquiring Fund. The Acquiring Fund will assume all of your fund's liabilities. The net asset value of both Pioneer Funds will be computed as of the close of regular trading on the New York Stock Exchange on the Closing Date. o The Acquiring Fund will issue Class A, Class C and Class Y shares to the Acquired Fund in amounts equal to the aggregate net asset value of the Acquired Fund's Class A, Class C and Class Y shares, respectively. o Shares of the Acquiring Fund will immediately be distributed to you in proportion to the relative net asset value of your holdings of shares of the applicable class or classes of the Acquired Fund on the Closing Date. As a result, the Acquired Fund's Class A shareholders will end up as Class A shareholders of the Acquiring Fund, and the Acquired Fund's Class C and Class Y shareholders will end up as Class C and Class Y shareholders, respectively, of the Acquiring Fund. The net asset value attributable to a class of shares of each fund will be determined using the Pioneer Funds' valuation policies and procedures. Each fund's valuation policies and procedures are identical. o After the shares are issued, the Acquired Fund will be dissolved. o No sales load, contingent deferred sales charge, commission, redemption fee or other transactional fee will be charged as a result of the Reorganization. After the Reorganization, any contingent deferred sales charge that applied to Class A (if applicable) or Class C shares of the Acquired Fund at the time of the Reorganization will continue to apply for the remainder of the applicable holding period at the time of the Reorganization. In calculating any applicable contingent deferred sales charge, the period during which you held your shares will be included in the holding period of the shares of the combined fund you receive as a result of the Reorganization. o The Reorganization generally is not expected to result in income, gain or loss being recognized for federal income tax purposes by shareholders of either Pioneer Fund involved in the Reorganization, or by either your fund or Pioneer Bond Fund involved in the Reorganization, except as set forth below under the heading "Tax Status of the Reorganization." The Reorganization will not take place unless both funds involved in the Reorganization receive a tax opinion from Morgan, Lewis & Bockius LLP, counsel to the funds, as described below under the heading "Tax Status of the Reorganization". Agreement and Plan of Reorganization The Agreement and Plan of Reorganization with respect to the Reorganization is attached as Exhibit A to this Information Statement/Prospectus. Material provisions of the Agreement and Plan of Reorganization are described below, but are qualified in their entirety by the attached copy. Cancellation of Share Certificates. If your shares are represented by one or more share certificates before the Closing Date, on the Closing Date all certificates will be canceled, will no longer evidence ownership of the Acquired Fund's shares and will evidence ownership of shares of the combined fund. The combined fund will not issue share certificates in the Reorganization. Conditions to Closing the Reorganization. The obligation of the Acquired Fund to consummate the Reorganization is subject to the satisfaction of certain conditions, including the performance by the Acquiring Fund of all its obligations under the Agreement and Plan of Reorganization and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Agreement and Plan of Reorganization, Section 6). The obligation of the Acquiring Fund to consummate the Reorganization is subject to the satisfaction of certain conditions, including the Acquired Fund's performance of all of its obligations under the Agreement and Plan of Reorganization, the receipt of certain documents and financial statements from that fund and the receipt of all consents, orders and permits necessary to consummate the Reorganization (see Agreement and Plan of Reorganization, Section 7). The funds' obligations are subject to the receipt of a favorable opinion of Morgan, Lewis & Bockius LLP as to the federal income tax consequences of the Reorganization (see Agreement and Plan of Reorganization, Section 8.4). Termination of Agreement and Plan of Reorganization. The Board of Trustees of either fund may terminate the Agreement and Plan of Reorganization at any time before the Closing Date, if the Board believes that proceeding with the Reorganization would no longer be in the best interests of shareholders of the applicable fund. 31 Expenses of the Reorganization. Each fund will bear approximately 25% of the expenses incurred in connection with the Reorganization, including expenses associated with the preparation, printing and mailing of any shareholder communications (including this Information Statement/Prospectus), any filings with the SEC and other governmental agencies in connection with the Reorganization, audit fees and legal fees ("Reorganization Costs"). Pioneer will bear the remaining 50% of the Reorganization Costs. TAX STATUS OF THE REORGANIZATION The Reorganization is conditioned upon the receipt by each fund of an opinion from Morgan, Lewis & Bockius LLP, counsel to the Pioneer Funds, substantially to the effect that, for federal income tax purposes: o The transfer to the Acquiring Fund of all of your fund's assets in exchange solely for the issuance of the Acquiring Fund's shares to your fund and the assumption of all of your fund's liabilities by the Acquiring Fund, followed by the distribution of the Acquiring Fund's shares in complete liquidation of your fund, will constitute a "reorganization" within the meaning of Section 368(a) of the Code, and each of your fund and Pioneer Bond Fund will be a "party to a reorganization" within the meaning of Section 368(b) of the Code; o No gain or loss will be recognized by your fund in the Reorganization upon (1) the transfer of all of its assets to the Acquiring Fund as described above or (2) the distribution by your fund of the Acquiring Fund's shares to your fund's shareholders in complete liquidation of your fund, except for (A) any gain or loss that may be recognized with respect to "section 1256 contracts" as defined in Section 1256(b) of the Code, (B) any gain that may be recognized on the transfer of stock in a "passive foreign investment company" as defined in Section 1297(a) of the Code, and (C) any other gain or loss that may be required to be recognized as a result of the closing of your fund's taxable year or upon the transfer of an asset regardless of whether such transfer would otherwise be a non-recognition transaction under the Code; o The tax basis in the hands of Pioneer Bond Fund of the assets of your fund transferred in the Reorganization will be the same as the tax basis of the assets in the hands of your fund immediately before the transfer of the assets, increased by the amount of gain (or decreased by the amount of loss), if any, recognized by your fund on the transfer; o The holding period of each asset of your fund in the hands of Pioneer Bond Fund, other than assets with respect to which gain or loss is required to be recognized in the Reorganization, will include the period during which that asset was held by your fund (except where investment activities of the Acquiring Fund will have the effect of reducing or eliminating the holding period with respect to an asset); o No gain or loss will be recognized by Pioneer Bond Fund upon its receipt of your fund's assets solely in exchange for shares of Pioneer Bond Fund and the assumption of your fund's liabilities; o You will not recognize gain or loss upon the exchange of your shares for shares of the Acquiring Fund as part of the Reorganization; o The aggregate tax basis of Acquiring Fund shares you receive in the Reorganization will be the same as the aggregate tax basis of the shares of your fund you surrender in the exchange; and o The holding period of Acquiring Fund shares you receive in the Reorganization will include the holding period of the shares of your fund that you surrender in the exchange, provided that you hold the shares of your fund as capital assets on the date of the exchange. In rendering such opinion, counsel shall rely upon, among other things, certain facts, assumptions and representations of your fund and the Acquiring Fund. The condition that each fund receives such an opinion may not be waived by either fund. No tax ruling has been or will be received from the Internal Revenue Service ("IRS") in connection with the Reorganization. An opinion of counsel is not binding on the IRS or a court, and no assurance can be given that the IRS would not assert, or a court would not sustain, a contrary position. Immediately prior to the Reorganization, your fund will declare and pay a dividend, which, together with all previous dividends, is intended to have the effect of distributing to your fund's shareholders all of your fund's investment company taxable income (computed without regard to the dividends-paid deduction), all of its net tax-exempt income, and all of its net capital gain (after deduction for any available capital loss carryover) for taxable years ending on or prior to the Closing. The amount of such distribution to the shareholders 32 of your fund is estimated as of October 31, 2015 to be as set forth in the table below. The amount set forth in the table below is an estimate based on your fund's income and capital gains expected to be realized as if its taxable year ended on the Closing Date. Amounts actually distributed to shareholders immediately prior to the Reorganization may be higher or lower than the amounts set forth in the table below. Fund Distribution Amount (per share)(unaudited) -------------------------------------------------------------- Pioneer Government Income Fund $ -- -------------------------------------------------------------- Such distributions will generally result in taxable income to you. The foregoing discussion is very general and does not take into account any considerations that may apply to certain classes of taxpayers who are subject to special circumstances, such as shareholders who are not citizens of or residents of the United States, insurance companies, tax-exempt organizations, financial institutions, dealers in securities or foreign currencies, or persons who hold their shares as part of a straddle or conversion transaction. You should consult your tax adviser for the particular tax consequences to you of the transaction, including the applicability of any state, local or foreign tax laws. 33 CLASSES OF SHARES OF THE FUNDS The table below provides information regarding the characteristics and fee structure of Class A, Class C and Class Y shares of the Pioneer Funds. The policies disclosed below apply to each Pioneer Fund. ------------------------------------------------------------------------------------------------------------------------------------ Class A sales charges The Class A shares of each Pioneer Fund have the same characteristics and fee structure. and fees o Class A shares are offered with an initial sales charge up to 4.50% of the offering price, which is reduced or waived for large purchases and certain types of investors. At the time of your purchase, your investment firm may receive a commission from the distributor of up to 4%, declining as the size of your investment increases. o There is no contingent deferred sales charge, except in certain circumstances when no initial sales charge is charged. o Class A shares are subject to distribution and service (12b-1) fees of up to 0.25% of average daily net assets. ------------------------------------------------------------------------------------------------------------------------------------ Class C sales charges The Class C shares of each Pioneer Fund have the same characteristics and fee structure. and fees o Class C shares are offered without an initial sales charge. o Class C shares are subject to a contingent deferred sales charge of 1% if you sell your shares within one year of purchase. Your investment firm may receive a commission from the distributor at the time of your purchase of up to 1%. o Class C shares are subject to distribution and service (12b-1) fees of 1.00% of average daily net assets. o Class C shares do not convert to another share class. o The maximum purchase amount (per transaction) for Class C shares is $499,999. ------------------------------------------------------------------------------------------------------------------------------------ Class Y sales charges The Class Y shares of each Pioneer Fund have the same characteristics and fee structure. and fees o Class Y shares are offered without an initial sales charge. o Class Y shares are not subject to a contingent deferred sales charge. o Class Y shares are not subject to distribution and service (12b-1) fees. o Initial investments are subject to a $5 million investment minimum, which may be waived in some circumstances. ------------------------------------------------------------------------------------------------------------------------------------ 34 BUYING, SELLING AND EXCHANGING SHARES OF THE FUNDS The table below provides information regarding how to buy, sell and exchange shares of the Pioneer Funds. The policies disclosed below apply to each Pioneer Fund. ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares ------------------------------------------------------------------------------------------------------------------------------------ Buying shares You may buy fund shares from any financial intermediary that has a sales agreement or other arrangement with the distributor. You can buy shares at net asset value per share plus any applicable sales charge. The distributor may reject any order until it has confirmed the order in writing and received payment. Normally, your financial intermediary will send your purchase request to the fund's transfer agent. Consult your investment professional for more information. Your investment firm receives a commission from the distributor, and may receive additional compensation from Pioneer, for your purchase of fund shares. ------------------------------------------------------------------------------------------------------------------------------------ Minimum initial Your initial investment must be at least $1,000 for Class A or Class C shares and at least $5 million for Class Y investment shares. Additional investments must be at least $100 for Class A shares and $500 for Class C shares. You may qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account, establishing an automatic investment plan or placing your trade through your investment firm. The fund may waive the initial or subsequent investment minimums. Minimum investment amounts may be waived for, among other things, share purchases made through certain mutual fund programs (e.g., asset based fee program accounts) sponsored by qualified intermediaries, such as broker-dealers and investment advisers, that have entered into an agreement with Pioneer. There is no minimum additional investment amount for Class Y shares. ------------------------------------------------------------------------------------------------------------------------------------ Maximum purchase Purchases of each Pioneer Fund shares are limited to $499,999 for Class C shares. These limits are applied on amounts a per transaction basis. There is no maximum purchase for Class A or Class Y shares. ------------------------------------------------------------------------------------------------------------------------------------ Exchanging shares You may, under certain circumstances, exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. The fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred sales charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. You generally will have to pay income taxes on an exchange. ------------------------------------------------------------------------------------------------------------------------------------ Selling shares Your shares will be sold at the share price (net asset value less any applicable sales charge) next calculated after the fund or its authorized agent, such as a broker-dealer, receives your request in good order. If a signature guarantee is required, you must submit your request in writing. If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. The fund generally will send your sale proceeds by check, bank wire or electronic funds transfer. Normally you will be paid within seven days. If you recently sent a check to purchase the shares being sold, the fund may delay payment of the sale proceeds until your check has cleared. This may take up to 10 calendar days from the purchase date. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below. If you are selling shares from a retirement account other than an IRA, you must make your request in writing. You generally will have to pay income taxes on a sale. If you must use a written request to exchange or sell your shares and your account is registered in the name of a corporation or other fiduciary you must include the name of an authorized person and a certified copy of a current corporate resolution, certificate of incumbency or similar legal document showing that the named individual is authorized to act on behalf of the record owner. ------------------------------------------------------------------------------------------------------------------------------------ 35 ------------------------------------------------------------------------------------------------------------------------------------ Buying, Selling and Exchanging Shares ------------------------------------------------------------------------------------------------------------------------------------ Net asset The fund's net asset value is the value of its securities plus any other assets minus its accrued operating value expenses and other liabilities. The fund calculates a net asset value for each class of shares every day the New York Stock Exchange is open as of the scheduled close of regular trading (normally 4:00 p.m. Eastern time). If the New York Stock Exchange closes at another time, the fund will calculate a net asset value for each class of shares as of the scheduled closing time. On days when the New York Stock Exchange is closed for trading, including certain holidays listed in the statement of additional information, a net asset value is not calculated. The fund's most recent net asset value is available on the fund's website, us.pioneerinvestments.com. The fund generally values debt securities and certain derivative instruments by using the prices supplied by independent third party pricing services. A pricing service may use market prices or quotations from one or more brokers or other sources, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. Senior loans are valued at the mean between the last available bid and asked prices for one or more brokers or dealers as obtained from an independent third party pricing service. If no reliable prices are available from either the primary or an alternative pricing service, broker quotes will be solicited. Event linked bonds are valued at the bid price obtained from an independent third party pricing service. Other insurance-linked securities may be valued at the bid price obtained from an independent third party pricing service, or through a third party using a pricing matrix, insurance industry valuation models, or other fair value methods or techniques to provide an estimated value of the instrument. The fund generally values its equity securities and certain derivative instruments that are traded on an exchange using the last sale price on the principal exchange on which they are traded. Equity securities that are not traded on the date of valuation, or securities for which no last sale prices are available, are valued at the mean between the last bid and asked prices or, if both last bid and asked prices are not available, at the last quoted bid price. Last sale, bid and asked prices are provided by independent third party pricing services. In the case of equity securities not traded on an exchange, prices are typically determined by independent third party pricing services approved by the Board of Trustees using a variety of techniques and methods. The fund may use a fair value model developed by an independent pricing service to value non-U.S. equity securities. To the extent that the fund invests in shares of other mutual funds that are not traded on an exchange, such shares of other mutual funds are valued at their net asset values as provided by those funds. The prospectuses for those funds explain the circumstances under which those funds will use fair value pricing methods and the effects of using fair value pricing methods. The valuations of securities traded in non-U.S. markets and certain fixed income securities will generally be determined as of the earlier closing time of the markets on which they primarily trade. When the fund holds securities or other assets that are denominated in a foreign currency, the fund will normally use the currency exchange rates as of 3:00 p.m. (Eastern time). Non-U.S. markets are open for trading on weekends and other days when the fund does not price its shares. Therefore, the value of the fund's shares may change on days when you will not be able to purchase or redeem fund shares. When independent third party pricing services are unable to supply prices for an investment, or when prices or market quotations are considered by Pioneer to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers. When such prices or quotations are not available, or when they are considered by Pioneer to be unreliable, the fund uses fair value methods to value its securities pursuant to procedures adopted by the Board of Trustees. The fund also may use fair value methods if it is determined that a significant event has occurred between the time at which a price is determined and the time at which the fund's net asset value is calculated. Because the fund may invest in securities rated below investment grade -- some of which may be thinly traded and for which prices may not be readily available or may be unreliable -- the fund may use fair value methods more frequently than funds that primarily invest in securities that are more widely traded. Valuing securities using fair value methods may cause the net asset value of the fund's shares to differ from the net asset value that would be calculated only using market prices. The prices used by the fund to value its securities may differ from the amounts that would be realized if these securities were sold and these differences may be significant, particularly for securities that trade in relatively thin markets and/or markets that experience extreme volatility. ------------------------------------------------------------------------------------------------------------------------------------ 36 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS Investment adviser Pioneer Investment Management, Inc., as each fund's investment adviser (the "Adviser"), selects the fund's investments and oversees the fund's operations. Pioneer is an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"), one of the largest banking groups in Italy. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of September 30, 2015, assets under management were approximately $243 billion worldwide, including over $66 billion in assets under management by Pioneer (and its U.S. affiliates). On November 11, 2015, UniCredit announced that it signed a binding master agreement with Banco Santander and affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the "Transaction"). The Transaction, as previously announced by UniCredit, will establish a holding company, with the name Pioneer Investments, to be owned by UniCredit (50%) and the Private Equity Firms (50% between them). The holding company will control Pioneer's U.S. operations, including the Adviser. The holding company also will own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco Santander will own directly the remaining 33.3% stake. The closing of the Transaction is expected to happen in 2016, subject to certain regulatory and other approvals. Under the Investment Company Act of 1940, completion of the Transaction will cause the Trust's investment advisory agreement with the Adviser to terminate. In connection with the Transaction, the Trust's Board of Trustees will be asked to approve a new investment advisory agreement for the Trust. If approved by the Board, the Trust's new investment advisory agreement will be submitted to the shareholders of the Trust for their approval. Pioneer Investment Management, Inc.'s main office is at 60 State Street, Boston, Massachusetts 02109. The firm's U.S. mutual fund investment history includes creating one of the first mutual funds in 1928. The Adviser has received an order from the Securities and Exchange Commission that permits Pioneer, subject to the approval of each Pioneer Fund's Board of Trustees, to hire and terminate a subadviser that is not affiliated with Pioneer (an "unaffiliated subadviser") or to materially modify an existing subadvisory contract with an unaffiliated subadviser for the Pioneer Fund without shareholder approval. Pioneer retains the ultimate responsibility to oversee and recommend the hiring, termination and replacement of any unaffiliated subadviser. Portfolio managers Day-to-day management of the Acquiring Fund's portfolio is the responsibility of Kenneth J. Taubes. Mr. Taubes is supported by Charles Melchreit. Mr. Taubes and Mr. Melchreit are supported by the fixed income team. Members of this team manage other Pioneer funds investing primarily in fixed income securities. The portfolio managers and the team also may draw upon the research and investment management expertise of the global research teams, which provide fundamental and quantitative research on companies and include members from one or more of Pioneer's affiliates. Mr. Taubes, Executive Vice President and Chief Investment Officer, U.S. of Pioneer, is responsible for overseeing the U.S. and global fixed income teams. He joined Pioneer as a senior vice president in September 1998 and has been an investment professional since 1982. Mr. Taubes has served as portfolio manager of the Acquiring Fund since 2004. Mr. Melchreit, Senior Vice President, joined Pioneer in 2006, and has served as portfolio manager of the Acquiring Fund since 2012. Distributor Pioneer Funds Distributor, Inc. is each Pioneer Fund's distributor. Each Pioneer Fund compensates the distributor for its services. The distributor is an affiliate of Pioneer. Disclosure of portfolio holdings Each Pioneer Fund's policies and procedures with respect to the disclosure of its portfolio securities are described in the fund's statement of additional information. 37 Distribution and service arrangements Distribution Plan Each Pioneer Fund has adopted a distribution plan for its Class A and Class C shares in accordance with Rule 12b-1 under the 1940 Act. Under each plan, a Pioneer Fund pays distribution and service fees to the distributor. Because these fees are an ongoing expense of a Pioneer Fund, over time they increase the cost of your investment and your shares may cost more than shares that are subject to other types of sales charges. Additional Payments to Financial Intermediaries Your financial intermediary may receive compensation from a Pioneer Fund, Pioneer and its affiliates for the sale of a Pioneer Fund's shares and related services. Compensation may include sales commissions and distribution and service (Rule 12b-1) fees, as well as compensation for administrative services and transaction processing. Pioneer and its affiliates may make additional payments to your financial intermediary. These payments may provide your financial intermediary with an incentive to favor the Pioneer funds over other mutual funds or assist the distributor in its efforts to promote the sale of a Pioneer Fund's shares. Financial intermediaries include broker-dealers, banks (including bank trust departments), registered investment advisers, financial planners, retirement plan administrators and other types of intermediaries. Pioneer makes these additional payments (sometimes referred to as "revenue sharing") to financial intermediaries out of its own assets, which may include profits derived from services provided to a Pioneer Fund, or from the retention of a portion of sales charges or distribution and service fees. Pioneer may base these payments on a variety of criteria, including the amount of sales or assets of the Pioneer funds attributable to the financial intermediary or as a per transaction fee. Not all financial intermediaries receive additional compensation and the amount of compensation paid varies for each financial intermediary. In certain cases, these payments may be significant. Pioneer determines which firms to support and the extent of the payments it is willing to make, generally choosing firms that have a strong capability to effectively distribute shares of the Pioneer funds and that are willing to cooperate with Pioneer's promotional efforts. Pioneer also may compensate financial intermediaries (in addition to amounts that may be paid by the fund) for providing certain administrative services and transaction processing services. Pioneer may benefit from revenue sharing if the intermediary features the Pioneer funds in its sales system (such as by placing certain Pioneer funds on its preferred fund list or giving access on a preferential basis to members of the financial intermediary's sales force or management). In addition, the financial intermediary may agree to participate in the distributor's marketing efforts (such as by helping to facilitate or provide financial assistance for conferences, seminars or other programs at which Pioneer personnel may make presentations on the Pioneer funds to the intermediary's sales force). To the extent intermediaries sell more shares of the Pioneer funds or retain shares of the Pioneer funds in their clients' accounts, Pioneer receives greater management and other fees due to the increase in the Pioneer funds' assets. The intermediary may earn a profit on these payments if the amount of the payment to the intermediary exceeds the intermediary's costs. The compensation that Pioneer pays to financial intermediaries is discussed in more detail in the fund's statement of additional information. Your intermediary may charge you additional fees or commissions other than those disclosed in this prospectus. Intermediaries may categorize and disclose these arrangements differently than in the discussion above and in the statement of additional information. You can ask your financial intermediary about any payments it receives from Pioneer or the Pioneer funds, as well as about fees and/or commissions it charges. Pioneer and its affiliates may have other relationships with your financial intermediary relating to the provision of services to the Pioneer funds, such as providing omnibus account services or effecting portfolio transactions for the Pioneer funds. If your intermediary provides these services, Pioneer or the Pioneer funds may compensate the intermediary for these services. In addition, your intermediary may have other relationships with Pioneer or its affiliates that are not related to the Pioneer funds. Initial Sales Charge (Class A Shares Only) You pay the offering price (the net asset value per share plus any initial sales charge) when you buy Class A shares unless you qualify to purchase shares at net asset value. You pay a lower sales charge as the size of your investment increases. You do not pay a sales charge when you reinvest dividends or capital gain distributions paid by a Pioneer Fund. 38 Sales Charges for Class A Shares ------------------------------------------------------------------------------------------------- Sales charge as % of ------------------------------------------------------------------------------------------------- Amount of Purchase Offering price Net amount invested ------------------------------------------------------------------------------------------------- Less than $100,000 4.50 4.71 ------------------------------------------------------------------------------------------------- $100,000 but less than $250,000 3.50 3.63 ------------------------------------------------------------------------------------------------- $250,000 but less than $500,000 2.50 2.56 ------------------------------------------------------------------------------------------------- $500,000 or more -0- -0- The dollar amount of the sales charge is the difference between the offering price of the shares purchased (based on the applicable sales charge in the table) and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge as a percentage of the offering price and of the net amount invested for any particular purchase of Pioneer Fund shares may be higher or lower due to rounding. Reduced sales charges You may qualify for a reduced Class A sales charge if you own or are purchasing shares of Pioneer mutual funds. The investment levels required to obtain a reduced sales charge are commonly referred to as "breakpoints." Pioneer offers two principal means of taking advantage of breakpoints in sales charges for aggregate purchases of Class A shares of the Pioneer funds over time if: o The amount of shares you own of the Pioneer funds plus the amount you are investing now is at least $100,000 (Rights of accumulation) o You plan to invest at least $100,000 over the next 13 months (Letter of intent) Rights of accumulation If you qualify for rights of accumulation, your sales charge will be based on the combined value (at the current offering price) of all your Pioneer mutual fund shares, the shares of your spouse and the shares of any children under the age of 21. Letter of intent You can use a letter of intent to qualify for reduced sales charges in two situations: o If you plan to invest at least $100,000 (excluding any reinvestment of dividends and capital gain distributions) in a Pioneer Fund's Class A shares during the next 13 months o If you include in your letter of intent the value (at the current offering price) of all of your Class A shares of a Pioneer Fund and Class A or Class C shares of all other Pioneer mutual fund shares held of record in the amount used to determine the applicable sales charge for Pioneer Fund shares you plan to buy Completing a letter of intent does not obligate you to purchase additional shares, but if you do not buy enough shares to qualify for the projected level of sales charges by the end of the 13-month period (or when you sell your shares, if earlier), the distributor will recalculate your sales charge. You must pay the additional sales charge within 20 days after you are notified of the recalculation or it will be deducted from your account (or your sale proceeds). Any share class for which no sales charge is paid cannot be included under the letter of intent. For more information regarding letters of intent, please contact your investment professional or obtain and read the statement of additional information. Qualifying for a reduced Class A sales charge In calculating your total account value in order to determine whether you have met sales charge breakpoints, you can include your Pioneer mutual fund shares, those of your spouse and the shares of any children under the age of 21. Pioneer will use each fund's current offering price to calculate your total account value. Certain trustees and fiduciaries may also qualify for a reduced sales charge. To receive a reduced sales charge, you or your investment professional must, at the time of purchase, notify the distributor of your eligibility. In order to verify your eligibility for a discount, you may need to provide your investment professional or the fund with information or records, such as account numbers or statements, regarding shares of the fund or other Pioneer mutual funds held in all accounts by you, your spouse or children under the age of 21 with that investment professional or with any other financial intermediary. Eligible accounts may include joint accounts, retirement plan accounts, such as IRA and 401k accounts, and custodial accounts, such as ESA, UGMA and UTMA accounts. 39 It is your responsibility to confirm that your investment professional has notified the distributor of your eligibility for a reduced sales charge at the time of sale. If you or your investment professional do not notify the distributor of your eligibility, you will risk losing the benefits of a reduced sales charge. For this purpose, Pioneer mutual funds include any fund for which the distributor is principal underwriter and, at the distributor's discretion, may include funds organized outside the U.S. and managed by Pioneer or an affiliate. You can locate information regarding the reduction or waiver of sales charges, in a clear and prominent format and free of charge, on Pioneer's website at www.pioneerinvestments.com. The website includes hyperlinks that facilitate access to this information. Class A purchases at net asset value You may purchase Class A shares at net asset value (without a sales charge) as follows. If you believe you qualify for any of the Class A sales charge waivers discussed below, contact your investment professional or the distributor. You are required to provide written confirmation of your eligibility. You may not resell these shares except to or on behalf of the fund. Class A purchases at net asset value are available to: o Current or former trustees and officers of the fund; o Partners and employees of legal counsel to the fund (at the time of initial share purchase); o Directors, officers, employees or sales representatives of Pioneer and its affiliates (at the time of initial share purchase); o Directors, officers, employees or sales representatives of any subadviser or a predecessor adviser (or their affiliates) to any investment company for which Pioneer serves as investment adviser (at the time of initial share purchase); o Officers, partners, employees or registered representatives of broker-dealers (at the time of initial share purchase) which have entered into sales agreements with the distributor; o Employees of Regions Financial Corporation and its affiliates (at the time of initial share purchase); o Members of the immediate families of any of the persons above; o Any trust, custodian, pension, profit sharing or other benefit plan of the foregoing persons; o Insurance company separate accounts; o Certain wrap accounts for the benefit of clients of investment professionals or other financial intermediaries adhering to standards established by the distributor; o Other funds and accounts for which Pioneer or any of its affiliates serves as investment adviser or manager; o Investors in connection with certain reorganization, liquidation or acquisition transactions involving other investment companies or personal holding companies; o Certain unit investment trusts; o Group employer-sponsored retirement plans with at least $500,000 in total plan assets. Waivers for group employer-sponsored retirement plans do not apply to traditional IRAs, Roth IRAs, SEPs, SARSEPs, SIMPLE IRAs, KEOGHs, individual 401(k) or individual 403(b) plans, or to brokerage relationships in which sales charges are customarily imposed; o Group employer-sponsored retirement plans with accounts established with Pioneer on or before March 31, 2004 with 100 or more eligible employees or at least $500,000 in total plan assets; o Participants in an employer-sponsored 403(b) plan or employer-sponsored 457 plan if (i) your employer has made special arrangements for your plan to operate as a group through a single broker, dealer or financial intermediary and (ii) all participants in the plan who purchase shares of a Pioneer mutual fund do so through a single broker, dealer or other financial intermediary designated by your employer; o Investors purchasing shares pursuant to the reinstatement privilege applicable to Class A shares; and o Shareholders of record (i.e., shareholders whose shares are not held in the name of a broker or an omnibus account) on the date of the reorganization of a predecessor Safeco fund into a corresponding Pioneer fund, shareholders who owned shares in the name of an omnibus account provider on that date that agrees with the fund to distinguish beneficial holders in the same manner, and retirement plans with assets invested in the predecessor Safeco fund on that date. 40 In addition, Class A shares may be purchased at net asset value through certain mutual fund programs sponsored by qualified intermediaries, such as broker-dealers and investment advisers. In each case, the intermediary has entered into an agreement with Pioneer to include the Pioneer funds in their program without the imposition of a sales charge. The intermediary provides investors participating in the program with additional services, including advisory, asset allocation, recordkeeping or other services. You should ask your investment firm if it offers and you are eligible to participate in such a mutual fund program and whether participation in the program is consistent with your investment goals. The intermediaries sponsoring or participating in these mutual fund programs also may offer their clients other classes of shares of the funds and investors may receive different levels of services or pay different fees depending upon the class of shares included in the program. Investors should consider carefully any separate transaction and other fees charged by these programs in connection with investing in each available share class before selecting a share class. Such mutual fund programs include certain self-directed brokerage services accounts held through qualified intermediaries that may or may not charge participating investors transaction fees. Contingent deferred sales charges (CDSCs) Class A shares Purchases of Class A shares of $500,000 or more, or by participants in a group plan which were not subject to an initial sales charge, may be subject to a contingent deferred sales charge upon redemption. A contingent deferred sales charge is payable to the distributor in the event of a share redemption within 12 months following the share purchase at the rate of 1% of the lesser of the value of the shares redeemed (exclusive of reinvested dividend and capital gain distributions) or the total cost of such shares. However, the contingent deferred sales charge is waived for redemptions of Class A shares purchased by an employer-sponsored retirement plan that has at least $500,000 in total plan assets (or that has 1,000 or more eligible employees for plans with accounts established with Pioneer on or before March 31, 2004). Class C shares You buy Class C shares at net asset value per share without paying an initial sales charge. However, if you sell your Class C shares within one year of purchase, upon redemption you will pay the distributor a contingent deferred sales charge of 1% of the current market value or the original cost of the shares you are selling, whichever is less. Paying the contingent deferred sales charge (CDSC) Several rules apply for calculating CDSCs so that you pay the lowest possible CDSC. o The CDSC is calculated on the current market value or the original cost of the shares you are selling, whichever is less o You do not pay a CDSC on reinvested dividends or distributions o If you sell only some of your shares, the transfer agent will first sell your shares that are not subject to any CDSC and then the shares that you have owned the longest o You may qualify for a waiver of the CDSC normally charged. See "Waiver or reduction of contingent deferred sales charges" Waiver or reduction of contingent deferred sales charges It is your responsibility to confirm that your investment professional has notified the distributor of your eligibility for a reduced sales charge at the time of sale. If you or your investment professional do not notify the distributor of your eligibility, you will risk losing the benefits of a reduced sales charge. The distributor may waive or reduce the CDSC for Class A shares that are subject to a CDSC or for Class C shares if: o The distribution results from the death of all registered account owners or a participant in an employer-sponsored plan. For UGMAs, UTMAs and trust accounts, the waiver applies only upon the death of all beneficial owners; o You become disabled (within the meaning of Section 72 of the Internal Revenue Code) after the purchase of the shares being sold. For UGMAs, UTMAs and trust accounts, the waiver only applies upon the disability of all beneficial owners; o The distribution is made in connection with limited automatic redemptions as described in "Systematic withdrawal plans" (limited in any year to 10% of the value of the account in the fund at the time the withdrawal plan is established); o The distribution is from any type of IRA, 403(b) or employer-sponsored plan described under Section 401(a) or 457 of the Internal Revenue Code and, in connection with the distribution, one of the following applies: 41 --It is part of a series of substantially equal periodic payments made over the life expectancy of the participant or the joint life expectancy of the participant and his or her beneficiary (limited in any year to 10% of the value of the participant's account at the time the distribution amount is established); --It is a required minimum distribution due to the attainment of age 70 1/2, in which case the distribution amount may exceed 10% (based solely on total plan assets held in Pioneer mutual funds); --It is rolled over to or reinvested in another Pioneer mutual fund in the same class of shares, which will be subject to the CDSC of the shares originally held; or --It is in the form of a loan to a participant in a plan that permits loans (each repayment applied to the purchase of shares will be subject to a CDSC as though a new purchase); o The distribution is to a participant in an employer-sponsored retirement plan described under Section 401(a) of the Internal Revenue Code or to a participant in an employer-sponsored 403(b) plan or employer-sponsored 457 plan if (i) your employer has made special arrangements for your plan to operate as a group through a single broker, dealer or financial intermediary and (ii) all participants in the plan who purchase shares of a Pioneer mutual fund do so through a single broker, dealer or other financial intermediary designated by your employer and is or is in connection with: --A return of excess employee deferrals or contributions; --A qualifying hardship distribution as described in the Internal Revenue Code; --Due to retirement or termination of employment; --From a qualified defined contribution plan and represents a participant's directed transfer, provided that this privilege has been preauthorized through a prior agreement with the distributor regarding participant directed transfers; o The distribution is made pursuant to the fund's right to liquidate or involuntarily redeem shares in a shareholder's account; o The distribution is made to pay an account's advisory or custodial fees; or o The distributor does not pay the selling broker a commission normally paid at the time of the sale.

Each Pioneer Fund is generally available for purchase in the United States, Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands. Except to the extent otherwise permitted by the Pioneer Funds' distributor, the Pioneer Funds will only accept accounts from U.S. citizens with a U.S. address (including an APO or FPO address) or resident aliens with a U.S. address (including an APO or FPO address) and a U.S. tax payer identification number. Identity verification To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you open an account, you will need to supply your name, address, date of birth, and other information that will allow the fund to identify you. 42 A Pioneer Fund may close your account if we cannot adequately verify your identity. The redemption price will be the net asset value on the date of redemption. Investing through financial intermediaries and retirement plans If you invest in a Pioneer Fund through your financial intermediary or through a retirement plan, the options and services available to you may be different from those discussed in this Information Statement / Prospectus. Shareholders investing through financial intermediaries, programs sponsored by financial intermediaries and retirement plans may only purchase funds and classes of shares that are available. When you invest through an account that is not in your name, you generally may buy and sell shares and complete other transactions only through the account. Ask your investment professional or financial intermediary for more information. Additional conditions may apply to your investment in a Pioneer Fund, and the investment professional or intermediary may charge you a transaction-based, administrative or other fee for its services. These conditions and fees are in addition to those imposed by the Pioneer Fund and its affiliates. You should ask your investment professional or financial intermediary about its services and any applicable fees. Share prices for transactions If you place an order to purchase, exchange or sell shares with the transfer agent or an authorized agent by the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time), the share price for your transaction will be based on the net asset value determined as of the close of regular trading on the New York Stock Exchange on that day (plus or minus any applicable sales charges). If your order is placed with the transfer agent or an authorized agent after the close of regular trading on the New York Stock Exchange, or your order is not in good order, the share price will be based on the net asset value next determined after your order is received in good order by the fund or authorized agent. The authorized agent is responsible for transmitting your order to the fund in a timely manner. Good order means that: o You have provided adequate instructions o There are no outstanding claims against your account o There are no transaction limitations on your account o If you have any fund share certificates, you submit them and they are signed by each record owner exactly as the shares are registered o Your request includes a signature guarantee if you: --Are selling over $100,000 or exchanging over $500,000 worth of shares --Changed your account registration or address within the last 30 days --Instruct the transfer agent to mail the check to an address different from the one on your account --Want the check paid to someone other than the account's record owner(s) --Are transferring the sale proceeds to a Pioneer mutual fund account with a different registration Transaction limitations Your transactions are subject to certain limitations, including the limitation on the purchase of a Pioneer Fund's shares within 30 calendar days of a redemption.

A Pioneer Fund may waive the initial or subsequent investment minimums. Minimum investment amounts may be waived for, among other things, share purchases made through certain mutual fund programs (e.g., asset based fee program accounts) sponsored by qualified intermediaries, such as broker-dealers and investment advisers, that have entered into an agreement with Pioneer. Class Y shares Your initial investment in Class Y shares must be at least $5 million. This amount may be invested in one or more of the Pioneer mutual funds that currently offer Class Y shares.

The intermediary provides investors participating in the program with additional services, including advisory, asset allocation, recordkeeping or other services. You should ask your investment firm if it offers and you are eligible to participate in such a mutual fund program and whether participation in the program is consistent with your investment goals. The intermediaries sponsoring or participating in these mutual fund programs may also offer their clients other classes of shares of the funds and investors may receive different levels of services or pay different fees depending upon the class of shares included in the program. Investors should consider carefully any separate transaction and other fees charged by these programs in connection with investing in each available share class before selecting a share class; or (f) The investment is made by another Pioneer fund. The fund reserves the right to waive the initial investment minimum in other circumstances. Maximum purchase amounts Purchases of shares of a Pioneer Fund are limited to $499,999 for Class C shares. This limit is applied on a per transaction basis. Class A and Class Y shares are not subject to a maximum purchase amount.

How to buy shares Through your investment firm Normally, your investment firm will send your purchase request to the Pioneer Funds' distributor and/or transfer agent. Consult your investment professional for more information. Your investment firm receives a commission from the distributor, and may receive additional compensation from Pioneer, for your purchase of shares of a Pioneer Fund. By phone or online You can use the telephone or online purchase privilege if you have an existing non-retirement account. Certain IRAs can use the telephone purchase privilege. If your account is eligible, you can purchase additional fund shares by phone or online if: o You established your bank account of record at least 30 days ago o Your bank information has not changed for at least 30 days o You are not purchasing more than $100,000 worth of shares per account per day o You can provide the proper account identification information When you request a telephone or online purchase, the transfer agent will electronically debit the amount of the purchase from your bank account of record. The transfer agent will purchase shares of the Pioneer Fund for the amount of the debit at the offering price determined after the transfer agent receives your telephone or online purchase instruction and good funds. It usually takes three business days for the transfer agent to receive notification from your bank that good funds are available in the amount of your investment. In writing, by mail You can purchase shares of a Pioneer Fund for an existing fund account by mailing a check to the fund. Make your check payable to the Pioneer Fund. Neither initial nor subsequent investments should be made by third party check, travelers check, or credit card check. Your check must be in U.S. dollars and drawn on a U.S. bank.

Please note that there may be a delay in receipt by the fund's transfer agent of purchase orders submitted by regular mail to a post office address. By wire (Class Y shares only) If you have an existing (Class Y shares only) account, you may wire funds to purchase shares. Note, however, that: o State Street Bank must receive your wire no later than 11:00 a.m. Eastern time on the business day after the Pioneer Fund receives your request to purchase shares o If State Street Bank does not receive your wire by 11:00 a.m. Eastern time on the next business day, your transaction will be canceled at your expense and risk o Wire transfers normally take two or more hours to complete and a fee may be charged by the sending bank o Wire transfers may be restricted on holidays and at certain other times Instruct your bank to wire funds to: Receiving Bank: State Street Bank and Trust Company 225 Franklin Street Boston, MA 02101 ABA Routing No. 011000028 For further credit to: Shareholder Name Existing Pioneer Account No. [Name of Pioneer Fund] 45 The transfer agent must receive your account application before you send your initial check or federal funds wire. In addition, you must provide a bank wire address of record when you establish your account. Exchanging You may, under certain circumstances, exchange your shares for shares of the same class of another Pioneer mutual fund. Your exchange request must be for at least $1,000. Each Pioneer Fund allows you to exchange your shares at net asset value without charging you either an initial or contingent deferred sales charge at the time of the exchange. Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your original purchase will determine your contingent deferred sales charge. Before you request an exchange, consider each fund's investment objective and policies as described in the fund's prospectus. You generally will have to pay income taxes on an exchange. Same-fund exchange privilege Certain shareholders may be eligible to exchange their shares for the Pioneer Fund's Class Y shares. If eligible, no sales charges or other charges will apply to any such exchange. Generally, shareholders will not recognize a gain or loss for federal income tax purposes upon such an exchange. Investors should contact their financial intermediary to learn more about the details of this privilege. How to exchange shares Through your investment firm Normally, your investment firm will send your exchange request to the Pioneer Fund's transfer agent. Consult your investment professional for more information about exchanging your shares.

Selling Your shares will be sold at the share price (net asset value less any applicable sales charge) next calculated after the Pioneer Fund or its authorized agent, such as a broker-dealer, receives your request in good order. If a signature guarantee is required, you must submit your request in writing. 46 If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds. Each Pioneer Fund generally will send your sale proceeds by check, bank wire or electronic funds transfer. Normally you will be paid within seven days. If you recently sent a check to purchase the shares being sold, the Pioneer Fund may delay payment of the sale proceeds until your check has cleared. This may take up to 10 calendar days from the purchase date. If you are selling shares from a non-retirement account or certain IRAs, you may use any of the methods described below. If you are selling shares from a retirement account other than an IRA, you must make your request in writing. You generally will have to pay income taxes on a sale. If you must use a written request to exchange or sell your shares and your account is registered in the name of a corporation or other fiduciary you must include the name of an authorized person and a certified copy of a current corporate resolution, certificate of incumbency or similar legal document showing that the named individual is authorized to act on behalf of the record owner. How to sell shares Through your investment firm Normally, your investment firm will send your request to sell shares to the Pioneer Funds' transfer agent. Consult your investment professional for more information. Each Pioneer Fund has authorized the distributor to act as its agent in the repurchase of fund shares from qualified investment firms. Each Pioneer Fund reserves the right to terminate this procedure at any time. By phone or online If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by phone or online. You may sell shares of a Pioneer Fund held in a retirement plan account by phone only if your account is an eligible IRA (tax penalties may apply). You may not sell your shares by phone or online if you have changed your address (for checks) or your bank information (for wires and transfers) in the last 30 days. You may receive your sale proceeds: o By check, provided the check is made payable exactly as your account is registered o By bank wire or by electronic funds transfer, provided the sale proceeds are being sent to your bank address of record For Class Y shares, shareholders may sell up to $5 million per account per day if the proceeds are directed to your bank account of record ($100,000 per account per day if the proceeds are not directed to your bank account of record).

Telephone transaction privileges If your account is registered in your name, you can buy, exchange or sell shares of the Pioneer Funds by telephone. If you do not want your account to have telephone transaction privileges, you must indicate that choice on your account application or by writing to the fund. When you request a telephone transaction the fund's transfer agent will try to confirm that the request is genuine. The transfer agent records the call, requires the caller to provide validating information for the account and sends you a written confirmation. Each Pioneer Fund may implement other confirmation procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker-dealer or other third party. If a Pioneer Fund's confirmation procedures are followed, neither the fund nor its agents will bear any liability for these transactions. Online transaction privileges If your account is registered in your name, you may be able to buy, exchange or sell fund shares online. Your investment firm may also be able to buy, exchange or sell your fund shares online. To establish online transaction privileges: o For new accounts, complete the online section of the account application o For existing accounts, complete an account options form, write to the transfer agent or complete the online authorization screen at www.pioneerinvestments.com. To use online transactions, you must read and agree to the terms of an online transaction agreement available on the Pioneer website. When you or your investment firm requests an online transaction the transfer agent electronically records the transaction, requires an authorizing password and sends a written confirmation. Each Pioneer Fund may implement other procedures from time to time. Different procedures may apply if you have a non-U.S. account or if your account is registered in the name of an institution, broker-dealer or other third party. You may not be able to use the online transaction privilege for certain types of accounts, including most retirement accounts. Automatic investment plans You can make regular periodic investments in a Pioneer Fund by setting up monthly bank drafts, government allotments, payroll deductions, a Pioneer Investomatic Plan and other similar automatic investment plans. Automatic investments may be made only through U.S. banks. You may use an automatic investment plan to establish a Class A share account with a small initial investment. If you have a Class C share account and your balance is at least $1,000, you may establish an automatic investment plan. Pioneer Investomatic Plan If you establish a Pioneer Investomatic Plan, the transfer agent will make a periodic investment in shares of a Pioneer Fund by means of a preauthorized electronic funds transfer from your bank account. Your plan investments are voluntary. You may discontinue your plan at any time or change the plan's dollar amount, frequency or investment date by calling or writing to the transfer agent. You should allow up to 30 days for the transfer agent to establish your plan. 48 Automatic exchanges You can automatically exchange your shares of a Pioneer Fund for shares of the same class of another Pioneer mutual fund. The automatic exchange will begin on the day you select when you complete the appropriate section of your account application or an account options form. In order to establish automatic exchange: o You must select exchanges on a monthly or quarterly basis o Both the originating and receiving accounts must have identical registrations o The originating account must have a minimum balance of $5,000 You may have to pay income taxes on an exchange. Distribution options Each Pioneer Fund offers three distribution options. Any shares of a Pioneer Fund you buy by reinvesting distributions will be priced at the applicable net asset value per share. (1) Unless you indicate another option on your account application, any dividends and capital gain distributions paid to you by a Pioneer Fund will automatically be invested in additional fund shares. (2) You may elect to have the amount of any dividends paid to you in cash and any capital gain distributions reinvested in additional shares. (3) You may elect to have the full amount of any dividends and/or capital gain distributions paid to you in cash. Options (2) and (3) are not available to retirement plan accounts or accounts with a current value of less than $500. If you are under 59 1/2, taxes and tax penalties may apply. If your distribution check is returned to the transfer agent or you do not cash the check for six months or more, the transfer agent may reinvest the amount of the check in your account and automatically change the distribution option on your account to option (1) until you request a different option in writing. If the amount of a distribution check would be less than $25, the Pioneer Fund may reinvest the amount in additional shares of the fund instead of sending a check. Additional shares of the Pioneer Fund will be purchased at the then-current net asset value. Directed dividends You can invest the dividends paid by one of your Pioneer mutual fund accounts in a second Pioneer mutual fund account. The value of your second account must be at least $1,000. You may direct the investment of any amount of dividends. There are no fees or charges for directed dividends. If you have a retirement plan account, you may only direct dividends to accounts with identical registrations. Systematic withdrawal plans When you establish a systematic withdrawal plan for your account, the transfer agent will sell the number of fund shares you specify on a periodic basis and the proceeds will be paid to you or to any person you select. You must obtain a signature guarantee to direct payments to another person after you have established your systematic withdrawal plan. Payments can be made either by check or by electronic transfer to a U.S. bank account you designate. To establish a systematic withdrawal plan: o Your account must have a total value of at least $10,000 when you establish your plan o You may not request a periodic withdrawal of more than 10% of the value of any Class C share account (valued at the time the plan is implemented) These requirements do not apply to scheduled (Internal Revenue Code Section 72(t) election) or mandatory (required minimum distribution) withdrawals from IRAs and certain retirement plans. Systematic sales of fund shares may be taxable transactions for you. While you are making systematic withdrawals from your account, you may pay unnecessary initial sales charges on additional purchases of Class A shares or contingent deferred sales charges. 49 Direct deposit If you elect to take dividends or dividends and capital gain distributions in cash, or if you establish a systematic withdrawal plan, you may choose to have those cash payments deposited directly into your savings, checking or NOW bank account. Voluntary tax withholding You may have the transfer agent withhold 28% of the dividends and capital gain distributions paid from your fund account (before any reinvestment) and forward the amount withheld to the Internal Revenue Service as a credit against your federal income taxes. Voluntary tax withholding is not available for retirement plan accounts or for accounts subject to backup withholding. Shareholder services and policies Excessive trading Frequent trading into and out of a Pioneer Fund can disrupt portfolio management strategies, harm the Pioneer Fund's performance by forcing the Pioneer Fund to hold excess cash or to liquidate certain portfolio securities prematurely and increase expenses for all investors, including long-term investors who do not generate these costs. An investor may use short-term trading as a strategy, for example, if the investor believes that the valuation of the Pioneer Fund's portfolio securities for purposes of calculating its net asset value does not fully reflect the then-current fair market value of those holdings. Each Pioneer Fund discourages, and does not take any intentional action to accommodate, excessive and short-term trading practices, such as market timing. Although there is no generally applied standard in the marketplace as to what level of trading activity is excessive, we may consider trading in a Pioneer Fund's shares to be excessive for a variety of reasons, such as if: o You sell shares within a short period of time after the shares were purchased; o You make two or more purchases and redemptions within a short period of time; o You enter into a series of transactions that indicate a timing pattern or strategy; or o We reasonably believe that you have engaged in such practices in connection with other mutual funds. Each Pioneer Fund's Board of Trustees has adopted policies and procedures with respect to frequent purchases and redemptions of fund shares by investors in the Pioneer Fund. Pursuant to these policies and procedures, we monitor selected trades on a daily basis in an effort to detect excessive short-term trading. If we determine that an investor or a client of a broker or other intermediary has engaged in excessive short-term trading that we believe may be harmful to a Pioneer Fund, we will ask the investor, broker or other intermediary to cease such activity and we will refuse to process purchase orders (including purchases by exchange) of such investor, broker, other intermediary or accounts that we believe are under their control. In determining whether to take such actions, we seek to act in a manner that is consistent with the best interests of the shareholders of the Pioneer Fund. While we use our reasonable efforts to detect excessive trading activity, there can be no assurance that our efforts will be successful or that market timers will not employ tactics designed to evade detection. If we are not successful, your return from an investment in a Pioneer Fund may be adversely affected. Frequently, shares of a Pioneer Fund are held through omnibus accounts maintained by financial intermediaries such as brokers and retirement plan administrators, where the holdings of multiple shareholders, such as all the clients of a particular broker or other intermediary, are aggregated. Our ability to monitor trading practices by investors purchasing shares through omnibus accounts may be limited and dependent upon the cooperation of the broker or other intermediary in taking steps to limit this type of activity. Each Pioneer Fund may reject a purchase or exchange order before its acceptance or the issuance of shares. Each Pioneer Fund may also restrict additional purchases or exchanges in an account. Each of these steps may be taken for any transaction, for any reason, without prior notice, including transactions that the Pioneer Fund believes are requested on behalf of market timers. Each Pioneer Fund reserves the right to reject any purchase or exchange request by any investor or financial institution if the Pioneer Fund believes that any combination of trading activity in the account or related accounts is potentially disruptive to the fund. A prospective investor whose purchase or exchange order is rejected will not achieve the investment results, whether gain or loss, that would have been realized if the order had been accepted and an investment made in the fund. A Pioneer Fund and its shareholders do not incur any gain or loss as a result of a rejected order. Each Pioneer Fund may impose further restrictions on trading activities by market timers in the future. To limit the negative effects of excessive trading, each Pioneer Fund has adopted the following restriction on investor transactions. If an investor redeems $5,000 or more (including redemptions that are a part of an exchange transaction) from a Pioneer Fund, that investor shall be prevented (or "blocked") from purchasing shares of the Pioneer Fund (including purchases that are a part of an exchange transaction) for 30 calendar days after the redemption. This policy does not apply to systematic purchase or withdrawal plan transactions, transactions made through employer-sponsored retirement plans described under Section 401(a), 403(b) or 457 of the Internal Revenue Code or employee benefit plans, scheduled (Internal Revenue Code Section 72(t) election) or mandatory (required minimum distribution) withdrawals 50 from IRAs, rebalancing transactions made through certain asset allocation or "wrap" programs, transactions by insurance company separate accounts or transactions by other funds that invest in the Pioneer Fund. This policy does not apply to purchase or redemption transactions of less than $5,000 or to Pioneer U.S. Government Money Market Fund or Pioneer Multi-Asset Ultrashort Income Fund. We rely on financial intermediaries that maintain omnibus accounts to apply to their customers either the Pioneer Funds' policy described above or the intermediaries' own policies or restrictions designed to limit excessive trading of shares of a Pioneer Fund. However, we do not impose this policy at the omnibus account level. Purchases pursuant to the reinstatement privilege (for Class A shares) are subject to this policy. Purchases in kind You may use securities you own to purchase shares of a Pioneer Fund provided that Pioneer, in its sole discretion, determines that the securities are consistent with the Pioneer Fund's objective and policies and their acquisition is in the best interests of the Pioneer Fund. If the fund accepts your securities, they will be valued for purposes of determining the number of shares of the Pioneer Fund to be issued to you in the same way the fund will value the securities for purposes of determining its net asset value. For federal income tax purposes, you may be taxed in the same manner as if you sold the securities that you use to purchase shares of the Pioneer Fund for cash in an amount equal to the value of the shares of the Pioneer Fund that you purchase. Your broker may also impose a fee in connection with processing your purchase of shares of a Pioneer Fund with securities. Reinstatement privilege (Class A shares) If you recently sold all or part of your Class A shares, you may be able to reinvest all or part of your sale proceeds without a sales charge in Class A shares of any Pioneer mutual fund. To qualify for reinstatement: o You must send a written request to the transfer agent no more than 90 days after selling your shares and o The registration of the account in which you reinvest your sale proceeds must be identical to the registration of the account from which you sold your shares. Purchases pursuant to the reinstatement privilege are subject to limitations on investor transactions, including the limitation on the purchase of a Pioneer Fund's shares within 30 calendar days of redemption. See "Excessive trading." When you elect reinstatement, you are subject to the provisions outlined in the selected the Pioneer Fund's prospectus, including the fund's minimum investment requirement. Your sale proceeds will be reinvested in shares of the Pioneer Fund at the Class A net asset value per share determined after the transfer agent receives your written request for reinstatement. You may realize a gain or loss for federal income tax purposes as a result of your sale of shares of a Pioneer Fund, and special tax rules may apply if you elect reinstatement.

Household delivery of fund documents With your consent, Pioneer may send a single proxy statement, prospectus and shareowner report to your residence for you and any other member of your household who has an account with a Pioneer Fund. If you wish to revoke your consent to this practice, you may do so by notifying Pioneer, by phone or in writing (see "How to contact us"). Pioneer will begin mailing separate proxy statements, prospectuses and shareowner reports to you within 30 days after receiving your notice. Confirmation statements The Pioneer Funds' transfer agent maintains an account for each investment firm or individual shareowner and records all account transactions. You will be sent confirmation statements showing the details of your transactions as they occur, except automatic investment plan transactions, which are confirmed quarterly. If you have more than one Pioneer mutual fund account registered in your name, the Pioneer combined account statement will be mailed to you each quarter. Tax information Early each year, each Pioneer Fund will mail you information about the tax status of the dividends and distributions paid to you by the Pioneer Fund. Tax information for IRA rollovers In January (or by the applicable Internal Revenue Service deadline) following the year in which you take a reportable distribution, the Pioneer Funds' transfer agent will mail you a tax form reflecting the total amount(s) of distribution(s) received by the end of January. Privacy Each Pioneer Fund has a policy designed to protect the privacy of your personal information. A copy of Pioneer's privacy notice was given to you at the time you opened your account. Each Pioneer Fund will send you a copy of the privacy notice each year. You may also obtain the privacy notice by calling the fund or through Pioneer's website. Signature guarantees and other requirements You are required to obtain a signature guarantee when: o Requesting certain types of exchanges or sales of shares of a Pioneer Fund o Redeeming shares for which you hold a share certificate o Requesting certain types of changes for your existing account You can obtain a signature guarantee from most broker-dealers, banks, credit unions (if authorized under state law) and federal savings and loan associations. You cannot obtain a signature guarantee from a notary public. The Pioneer funds generally accept only medallion signature guarantees. A medallion signature guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution that is participating in a medallion program recognized by the Securities Transfer Association. Signature guarantees from financial institutions that are not participating in one of these programs are not accepted as medallion signature guarantees. A Pioneer Fund may accept other forms of guarantee from financial intermediaries in limited circumstances. Fiduciaries and corporations are required to submit additional documents to sell shares of a Pioneer Fund. 52 Minimum account size The fund requires that you maintain a minimum account value of $500. If you hold less than $500 in your account, each Pioneer Fund reserves the right to notify you that it intends to sell your shares and close your account. You will be given 60 days from the date of the notice to make additional investments to avoid having your shares sold. This policy does not apply to certain qualified retirement plan accounts. Telephone and website access You may have difficulty contacting a Pioneer Fund by telephone or accessing www.pioneerinvestments.com during times of market volatility or disruption in telephone or Internet service. On New York Stock Exchange holidays or on days when the exchange closes early, Pioneer will adjust the hours for the telephone center and for online transaction processing accordingly. If you are unable to access www.pioneerinvestments.com or reach a Pioneer Fund by telephone, you should communicate with the Pioneer Fund in writing. Share certificates The Pioneer Funds do not offer share certificates. Shares are electronically recorded. Any existing certificated shares can only be sold by returning your certificate to the transfer agent, along with a letter of instruction or a stock power (a separate written authority transferring ownership) and a signature guarantee. Other policies Each Pioneer Fund and the distributor reserve the right to: o reject any purchase or exchange order for any reason, without prior notice o charge a fee for exchanges or to modify, limit or suspend the exchange privilege at any time without notice. Each Pioneer Fund will provide 60 days' notice of material amendments to or termination of the exchange privilege o revise, suspend, limit or terminate the account options or services available to shareowners at any time, except as required by the rules of the Securities and Exchange Commission Each Pioneer Fund reserves the right to: o suspend transactions in shares when trading on the New York Stock Exchange is closed or restricted, or when the Securities and Exchange Commission determines an emergency or other circumstances exist that make it impracticable for the Pioneer Fund to sell or value its portfolio securities, or otherwise as permitted by the rules of or by the order of the Securities and Exchange Commission o redeem in kind by delivering to you portfolio securities owned by the Pioneer Fund rather than cash. Securities you receive this way may increase or decrease in value while you hold them and you may incur brokerage and transaction charges and tax liability when you convert the securities to cash o charge transfer, shareholder servicing or similar agent fees, such as an account maintenance fee for small balance accounts, directly to accounts upon at least 30 days' notice. A Pioneer Fund may do this by deducting the fee from your distribution of dividends and/or by redeeming fund shares to the extent necessary to cover the fee o close your account after a period of inactivity, as determined by state law, and transfer your shares to the appropriate state Dividends, capital gains and taxes Dividends and capital gains Each Pioneer Fund declares dividends daily. The daily dividends consist of substantially all of the Pioneer Fund's net income (excluding any net short- and long-term capital gains). You begin to earn dividends on the first business day following receipt of payment for shares. You continue to earn dividends up to and including the date of sale. Dividends are normally paid on the last business day of each month. Each Pioneer Fund generally pays any distribution of net short- and long-term capital gains in November. Each Pioneer Fund may also pay dividends and capital gain distributions at other times if necessary for the fund to avoid U.S. federal income or excise tax. If you invest in a Pioneer Fund shortly before a distribution described in this paragraph, generally you will pay a higher price per share and, unless you are exempt from tax, you will pay taxes on the amount of the distribution whether you reinvest the distribution in additional shares or receive it as cash. 53 Taxes You will normally have to pay federal income taxes, and any state or local taxes, on the dividends and other distributions you receive from a Pioneer Fund, whether you take the distributions in cash or reinvest them in additional shares. For U.S. federal income tax purposes, distributions from a Pioneer Fund's net capital gains (if any) are considered long-term capital gains and are generally taxable to noncorporate shareholders at rates of up to 20%. Distributions from a Pioneer Fund's net short-term capital gains are generally taxable as ordinary income. Other dividends are generally taxable as ordinary income. Since the Pioneer Funds's income is derived primarily from sources that do not pay dividends, it is not expected that a substantial portion of the dividends paid by the Pioneer Funds will qualify either for the dividends-received deduction for corporations or for any favorable U.S. federal income tax rate available to noncorporate shareholders on "qualified dividend income." Each Pioneer Fund will report to shareholders annually the U.S. federal income tax status of all fund distributions. If a Pioneer Fund declares a dividend in October, November or December, payable to shareholders of record in such a month, and pays it in January of the following year, you will be taxed on the dividend as if you received it in the year in which it was declared. Sales and exchanges generally will be taxable transactions to shareowners. When you sell or exchange Pioneer Fund shares you will generally recognize a capital gain or capital loss in an amount equal to the difference between the net amount of sale proceeds (or, in the case of an exchange, the fair market value of the shares) that you receive and your tax basis for the shares that you sell or exchange. A 3.8% Medicare contribution tax generally applies to all or a portion of the net investment income of a shareholder who is an individual and not a nonresident alien for federal income tax purposes and who has adjusted gross income (subject to certain adjustments) that exceeds a threshold amount. This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. For these purposes, dividends, interest and certain capital gains are generally taken into account in computing a shareholder's net investment income. You must provide your social security number or other taxpayer identification number to the applicable Pioneer Fund along with the certifications required by the Internal Revenue Service when you open an account. If you do not or if it is otherwise legally required to do so, the Pioneer Fund will apply "backup withholding" tax on your dividends and other distributions, sale proceeds and any other payments to you that are subject to backup withholding. The backup withholding rate is 28%. Shareholders that are exempt from U.S. federal income tax, such as retirement plans that are qualified under Section 401 of the Internal Revenue Code, generally are not subject to U.S. federal income tax on Pioneer Fund dividends or other distributions or on sales or exchanges of Pioneer Fund shares. However, in the case of Pioneer Fund shares held through a nonqualified deferred compensation plan, Pioneer Fund dividends and other distributions received by the plan and sales and exchanges of Pioneer Fund shares by the plan generally will be taxable to the employer sponsoring such plan in accordance with U.S. federal income tax laws that are generally applicable to shareholders receiving such dividends and other distributions from regulated investment companies such as the applicable Pioneer Fund or effecting such sales or exchanges. Plan participants whose retirement plan invests in a Pioneer Fund generally are not subject to federal income tax on the Pioneer Fund's dividends or other distributions received by the plan or on sales or exchanges of the Pioneer Fund's shares by the plan. However, distributions to plan participants from a retirement plan generally are taxable to plan participants as ordinary income. Distributions derived from interest on U.S. government obligations (but generally not distributions of gain from the sale of such obligations) may be exempt from certain state and local taxes. You should ask your tax adviser about any federal, state, local and foreign tax considerations relating to an investment in a Pioneer Fund. You may also consult the Pioneer Fund's statement of additional information for a more detailed discussion of the U.S. federal income tax considerations that may affect the Pioneer Fund and its shareowners. 54 FINANCIAL HIGHLIGHTS The financial highlights table helps you understand the Acquiring Fund's financial performance for the past five years and, if applicable, for any recent semiannual period. Certain information reflects financial results for a single fund share.

(*) Attached as Exhibit A to the combined Information Statement/Prospectus (**) Filed herewith. ITEM 17. UNDERTAKINGS. (1) The undersigned Registrant agrees that prior to any public reoffering of the securities registered through the use of a prospectus which is part of this Registration Statement by any person or party which is deemed to be an underwriter within the meaning of Rule 145(c) of the Securities Act of 1933, the reoffering prospectus will contain the information called for by the applicable registration form for the reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (2) The undersigned Registrant agrees that every prospectus that is filed under paragraph (1) above will be filed as part of an amendment to the Registration Statement and will not be used until the amendment is effective, and that, in determining any liability under the Securities Act of 1933, each post-effective amendment shall be deemed to be a new registration statement for the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering of them. (3) The undersigned Registrant agrees that it shall file a final executed version of the legal and consent opinion as to tax matters as an exhibit to the subsequent post-effective amendment to its registration statement on Form N-14 filed with the SEC upon the closing of the reorganization contemplated by this Registration Statement on Form N-14. (4) Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. SIGNATURES As required by the Securities Act of 1933, this Registration Statement on Form N-14 has been signed on behalf of the Registrant, in the City of Boston and the Commonwealth of Massachusetts, on the 22nd day of December, 2015.
