Consider these risks before investing: Investments in small and/or midsize companies increase the risk of greater price fluctuations. Growth stocks may be more susceptible to earnings disappointments, and the market may not favor growth-style investing. The prices of stocks in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including both general financial market conditions and factors related to a specific company or industry.

Message from the Trustees

Dear Fellow Shareholder:

Stock markets around the world have continued to show strength into 2013, with the S&P 500 Index delivering its best January return since 1997. Investors witnessed several positive developments, including the U.S. fiscal cliff bill that Congress passed on January 1, 2013; the improving employment and housing situations; a more stable Europe; and China’s “soft landing” and positive growth.

Today’s market environment is one of slow and steady improvement, but uncertainties linger. Questions remain about potential economic fallout from the upcoming debt ceiling and budget sequestration debates in the United States. And the sovereign debt situation in Europe, while stabilized, is far from resolved.

At Putnam, our investment team is focused on actively managing risk and pursuing returns in today’s volatile global market. As always, it is important to rely on the guidance of your financial advisor to help you manage your investment portfolio in accordance with your goals and risk tolerance.

We would also like to extend a welcome to new shareholders of the fund and to thank all of our investors for your continued confidence in Putnam.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. Share price, principal value, and return will fluctuate, and you may have a gain or a loss when you sell your shares. Performance of class A shares assumes reinvestment of distributions and does not account for taxes. Fund returns in the bar chart do not reflect a sales charge of 5.75%; had they, returns would have been lower. See pages 5 and 10–12 for additional performance information. For a portion of the periods, the fund had expense limitations, without which returns would have been lower. To obtain the most recent month-end performance, visit putnam.com.

* The fund’s benchmark, the Russell 1000 Growth Index, was introduced on 12/31/78, which post-dates the inception of the fund’s class A shares.

† Returns for the six-month period are not annualized, but cumulative.

Interview with your fund’s portfolio manager

Could you tell us about the investing environment for the six months ended January 31, 2013?

When the period began, U.S. stocks were enjoying a considerable upswing, with major stock market indexes beginning to reach multi-year highs. I believe the fuel for a powerful rally had been with us for some time, but we needed to get investor confidence back. In the period’s early months, we made progress on that front, and the market was able to “climb a wall of worry” as investors reacted favorably to a host of economic stimulus actions. The European Central Bank announced new measures to free up sovereign debt markets, followed by the U.S. Federal Reserve announcing a third round of aggressive quantitative easing. Later in the period, as we approached the U.S. presidential election, some turbulence returned to the markets, but stocks recovered quickly and delivered solid performance in the final two months of the period.

How did large-cap growth stocks and the fund perform in this environment?

The fund outperformed both its benchmark and the average return for funds within its Lipper peer group. Large-cap growth stocks, as measured by the fund’s benchmark, the Russell 1000 Growth Index, had slightly lower returns than the broader stock market, but performed well for the period.

This comparison shows your fund’s performance in the context of broad market indexes for the six months ended 1/31/13. See pages 4 and 10–12 for additional fund performance information. Index descriptions can be found on page 14.

It was an encouraging period for my investment approach, as we saw a reversal of many of the market trends and anomalies that had been affecting the fund’s relative performance for some time.

It is worth noting the change for cyclical stocks — those whose performance tends to be tied to overall economic conditions. Many cyclical companies that had started with low valuations and were growing their earnings rapidly — the types of stocks I target — had been performing poorly on a relative basis over the past couple of years.

Despite their underperformance, I continued to hold many of these cyclical stocks, which I believed offered a combination of above-average growth potential and attractive valuations. During the period, investors finally began to recognize, and pay for, the investment potential in these companies, and fund performance was rewarded.

In light of the stock market’s strength, have you made any shifts in the positioning of the fund’s portfolio?

A number of cyclical holdings in the portfolio have advanced considerably in recent months, and in some cases, I have trimmed the fund’s exposure. Beyond these small shifts, however, my strategy remains intact and I have made no major thematic changes in the stocks I am pursuing. I strive to construct a portfolio with higher forward growth rates for earnings and cash flow than those of the Russell 1000 Growth Index, but to do so without paying too much for that growth.

What were some examples of stocks that helped fund performance for the period?

One example of a stock that helped performance is General Motors. It began the period with a price-earnings ratio of approximately 6x consensus earnings expectations for 2013. I added it to the portfolio based on anticipated improvement in the U.S.

automobile market, a significant product cycle ahead for the company, and a very strong balance sheet position that I believed would aid its long-term earnings growth. I also believed it offered a low valuation relative to the company’s growth outlook. As U.S. auto sales continued their solid improvement despite macroeconomic concerns, and as the company bought back a very large stake from the government, the stock rallied sharply.

One of the more dramatic examples of the stock market rebound can be found in the financials sector — which is clearly reflected in the fund’s top performers. Among the top contributors to returns for the period were The Hartford Financial Services Group, an insurance and financial services company; JPMorgan Chase and Citigroup, both financial services companies; and Assured Guaranty, a credit protection company.

The resurgence of the financials sector illustrates how the market has refocused on the fundamental strengths of companies. Just one to two years ago, investors shunned almost all companies in the sector, despite the fact that most of them were delivering strong financial performance. Finally, in 2012, these stocks came roaring back, and it was the top-performing sector in the S&P 500. It takes conviction — and sometimes quite a bit of patience — to capitalize on these types of opportunities.

This table shows the fund’s top 10 holdings by percentage of the fund’s net assets as of 1/31/13. Short-term holdings are excluded. Holdings will vary over time.

What were some examples of stocks that hurt performance?

Best Buy, a large retailer of consumer electronics, has been hurt by perceptions of an increasingly competitive environment and by management changes. While the shift to online purchases is a well-known challenge, we believe the potential impact on the company may be less than investors believe. In our view, cost-cutting opportunities and strong free-cash-flow generation position the company for higher growth than the market expects. And, it is worth noting that the stock rebounded considerably in the final month of the period, in part due to better-than-expected holiday sales. Other detractors included Tronox, a producer of titanium ore, and Apple.

What is your outlook for investment opportunities in the second half of the fund’s fiscal year?

For an active manager focused on bottom-up stock selection and fundamental research, I believe the opportunities are tremendous. We see companies with strong fundamentals that appear likely to continue growing their earnings, but there is some aspect of their business that investors remain skeptical about. Or, perhaps the companies are out of favor due to the cyclicality of their industry.

We continue to focus on fundamental research, seeking stocks with the right combination of solid growth and low valuations. I believe the portfolio could benefit if the market continues to follow fundamentals, and investors are willing to pay reasonable multiples for this growth potential.

Thank you, Nick, for your time and insights today.

IN THE NEWS

Mixed signals are coming from the U.S. economy. On the positive side, the unemployment rate continues to tick down, the housing sector is recovering, and the stock market has reached multi-year highs. But uncertainty remains. The nation’s GDP was essentially flat in the fourth quarter of 2012, after several consecutive quarters of expansion. A precipitous drop in military spending contributed to the slowdown, and many questions remain about government spending and its impact on GDP going forward. Consumer confidence recently dropped following the tax increases resulting from the fiscal cliff resolution, as people anticipate the pinch of less take-home pay. The next few months should provide clearer direction for the markets on government spending and the resilience of the recovery.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. After-sales-charge returns for class A and M shares reflect the deduction of the maximum 5.75% and 3.50% sales charge, respectively, levied at the time of purchase. Class B share returns after contingent deferred sales charge (CDSC) reflect the applicable CDSC, which is 5% in the first year, declining over time to 1% in the sixth year, and is eliminated thereafter. Class C share returns after CDSC reflect a 1% CDSC for the first year that is eliminated thereafter. Class R, R5, R6, and Y shares have no initial sales charge or CDSC. Performance for class B, C, M, R, and Y shares before their inception is derived from the historical performance of class A shares, adjusted for the applicable sales charge (or CDSC) and the higher operating expenses for such shares, except for class Y shares, for which 12b-1 fees are not applicable. Performance for class R5 and R6 shares prior to their inception is derived from the historical performance of class Y shares and has not been adjusted for the lower investor servicing fees applicable to class R5 and R6 shares; had it, returns would have been higher.

Recent performance may have benefited from one or more legal settlements.

For a portion of the periods, the fund had expense limitations, without which returns would have been lower.

Class B share performance does not reflect conversion to class A shares.

Your fund’s expenses

As a mutual fund investor, you pay ongoing expenses, such as management fees, distribution fees (12b-1 fees), and other expenses. Using the following information, you can estimate how these expenses affect your investment and compare them with the expenses of other funds. You may also pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund’s prospectus or talk to your financial representative.

Terms and definitions

Important terms

Total return shows how the value of the fund’s shares changed over time, assuming you held the shares through the entire period and reinvested all distributions in the fund.

Before sales charge, or net asset value, is the price, or value, of one share of a mutual fund, without a sales charge. Before-sales-charge figures fluctuate with market conditions, and are calculated by dividing the net assets of each class of shares by the number of outstanding shares in the class.

After sales charge is the price of a mutual fund share plus the maximum sales charge levied at the time of purchase. After-sales-charge performance figures shown here assume the 5.75% maximum sales charge for class A shares and 3.50% for class M shares.

Contingent deferred sales charge (CDSC) is generally a charge applied at the time of the redemption of class B or C shares and assumes redemption at the end of the period. Your fund’s class B CDSC declines over time from a 5% maximum during the first year to 1% during the sixth year. After the sixth year, the CDSC no longer applies. The CDSC for class C shares is 1% for one year after purchase.

Share classes

Class A shares are generally subject to an initial sales charge and no CDSC (except on certain redemptions of shares bought without an initial sales charge).

Class B shares are not subject to an initial sales charge. They may be subject to a CDSC.

Class C shares are not subject to an initial sales charge and are subject to a CDSC only if the shares are redeemed during the first year.

Class M shares have a lower initial sales charge and a higher 12b-1 fee than class A shares and no CDSC (except on certain redemptions of shares bought without an initial sales charge).

Class R shares are not subject to an initial sales charge or CDSC and are available only to certain defined contribution plans.

Class R5 shares and class R6 shares are not subject to an initial sales charge or CDSC, and carry no 12b-1 fee. They are only available to certain defined contribution plans with assets of at least $50 million.

Class Y shares are not subject to an initial sales charge or CDSC, and carry no 12b-1 fee. They are generally only available to corporate and institutional clients and clients in other approved programs.

Financial statements

A guide to financial statements

These sections of the report, as well as the accompanying Notes, constitute the fund’s financial statements.

The fund’s portfolio lists all the fund’s investments and their values as of the last day of the reporting period. Holdings are organized by asset type and industry sector, country, or state to show areas of concentration and diversification.

Statement of assets and liabilities shows how the fund’s net assets and share price are determined. All investment and non-investment assets are added together. Any unpaid expenses and other liabilities are subtracted from this total. The result is divided by the number of shares to determine the net asset value per share, which is calculated separately for each class of shares. (For funds with preferred shares, the amount subtracted from total assets includes the liquidation preference of preferred shares.)

Statement of operations shows the fund’s net investment gain or loss. This is done by first adding up all the fund’s earnings — from dividends and interest income — and subtracting its operating expenses to determine net investment income (or loss). Then, any net gain or loss the fund realized on the sales of its holdings — as well as any unrealized gains or losses over the period — is added to or subtracted from the net investment result to determine the fund’s net gain or loss for the fiscal period.

Statement of changes in net assets shows how the fund’s net assets were affected by the fund’s net investment gain or loss, by distributions to shareholders, and by changes in the number of the fund’s shares. It lists distributions and their sources (net investment income or realized capital gains) over the current reporting period and the most recent fiscal year-end. The distributions listed here may not match the sources listed in the Statement of operations because the distributions are determined on a tax basis and may be paid in a different period from the one in which they were earned. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year.

Financial highlights provide an overview of the fund’s investment results, per-share distributions, expense ratios, net investment income ratios, and portfolio turnover in one summary table, reflecting the five most recent reporting periods. In a semiannual report, the highlights table also includes the current reporting period.

ASC 820 establishes a three-level hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund’s investments. The three levels are defined as follows:

Level 1: Valuations based on quoted prices for identical securities in active markets.

Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations based on inputs that are unobservable and significant to the fair value measurement.

The following is a summary of the inputs used to value the fund’s net assets as of the close of the reporting period:

Notes to financial statements 1/31/13 (Unaudited)

Within the following Notes to financial statements, references to “State Street” represent State Street Bank and Trust Company, references to “the SEC” represent the Securities and Exchange Commission, references to “Putnam Management” represent Putnam Investment Management, LLC, the fund’s manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC and references to “OTC”, if any, represent over-the-counter. Unless otherwise noted, the “reporting period” represents the period from August 1, 2012 through January 31, 2013.

Putnam Voyager Fund (the fund) is a Massachusetts business trust, which is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The investment objective of the fund is to seek capital appreciation by investing mainly in common stocks of midsize and large U.S. companies, with a focus on growth stocks. Growth stocks are issued by companies whose earnings are expected to grow faster than those of similar firms and whose business growth and other characteristics may lead to an increase in stock price. Putnam Management may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments.

The fund offers class A, class B, class C, class M, class R, class R5, class R6 and class Y shares. Class A and class M shares are sold with a maximum front-end sales charge of 5.75% and 3.50%, respectively, and generally do not pay a contingent deferred sales charge. Class B shares, which convert to class A shares after approximately eight years, do not pay a front-end sales charge and are subject to a contingent deferred sales charge if those shares are redeemed within six years of purchase. Class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. Class R shares, which are not available to all investors, are sold at net asset value. The expenses for class A, class B, class C, class M and class R shares may differ based on the distribution fee of each class, which is identified in Note 2. Class R5, class R6 and class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, class M and class R shares, but do not bear a distribution fee and in the case of class R5 and class R6 shares, bear a lower investor servicing fee, which is identified in Note 2. Class R5, class R6 and class Y shares are not available to all investors.

In the normal course of business, the fund enters into contracts that may include agreements to indemnify another party under given circumstances. The fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be, but have not yet been, made against the fund. However, the fund’s management team expects the risk of material loss to be remote.

Note 1: Significant accounting policies

The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations. Actual results could differ from those estimates. Subsequent events after the Statement of assets and liabilities date through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

Investment income, realized and unrealized gains and losses and expenses of the fund are borne pro-rata based on the relative net assets of each class to the total net assets of the fund, except that each class bears expenses unique to that class (including the distribution fees applicable to such classes). Each class votes as a class only with respect to its own distribution plan or other matters on which a class vote is required by law or determined by the Trustees. If the fund were liquidated, shares of each class would receive their pro-rata share of the net assets of the fund. In addition, the Trustees declare separate dividends on each class of shares.

Security valuation Investments for which market quotations are readily available are valued at the last reported sales price on their principal exchange, or official closing price for certain markets, and are classified as Level 1 securities under Accounting Standards Codification ASC 820 Fair Value Measurements and Disclosures (ASC 820). If no sales are reported, as in the case of some securities that are traded OTC, a security is valued at its last reported bid price and is generally categorized as a Level 2 security.

Investments in open-end investment companies (excluding exchange traded funds), if any, which can be classified as Level 1 or Level 2 securities, are based on their net asset value. The net asset value of such investment companies equals the total value of their assets less their liabilities and divided by the number of their outstanding shares.

34   Voyager Fund 

Market quotations are not considered to be readily available for certain debt obligations and other investments; such investments are valued on the basis of valuations furnished by an independent pricing service approved by the Trustees or dealers selected by Putnam Management. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities (which considers such factors as security prices, yields, maturities and ratings). These securities will generally be categorized as Level 2.

Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. Accordingly, on certain days, the fund will fair value foreign equity securities taking into account multiple factors including movements in the U.S. securities markets, currency valuations and comparisons to the valuation of American Depository Receipts, exchange-traded funds and futures contracts. These securities, which would generally be classified as Level 1 securities, will be transferred to Level 2 of the fair value hierarchy when they are valued at fair value. The number of days on which fair value prices will be used will depend on market activity and it is possible that fair value prices will be used by the fund to a significant extent. Securities quoted in foreign currencies, if any, are translated into U.S. dollars at the current exchange rate.

To the extent a pricing service or dealer is unable to value a security or provides a valuation that Putnam Management does not believe accurately reflects the security’s fair value, the security will be valued at fair value by Putnam Management. Certain investments, including certain restricted and illiquid securities and derivatives, are also valued at fair value following procedures approved by the Trustees. These valuations consider such factors as significant market or specific security events such as interest rate or credit quality changes, various relationships with other securities, discount rates, U.S. Treasury, U.S. swap and credit yields, index levels, convexity exposures and recovery rates. These securities are classified as Level 2 or as Level 3 depending on the priority of the significant inputs.

Such valuations and procedures are reviewed periodically by the Trustees. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securities over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the value of a security in a current sale and does not reflect an actual market price, which may be different by a material amount.

Security transactions and related investment income Security transactions are recorded on the trade date (the date the order to buy or sell is executed). Gains or losses on securities sold are determined on the identified cost basis.

Interest income, net of any applicable withholding taxes, is recorded on the accrual basis. Dividend income, net of any applicable withholding taxes, is recognized on the ex-dividend date except that certain dividends from foreign securities, if any, are recognized as soon as the fund is informed of the ex-dividend date. Non-cash dividends, if any, are recorded at the fair market value of the securities received. Dividends representing a return of capital or capital gains, if any, are reflected as a reduction of cost and/or as a realized gain.

All premiums/discounts are amortized/accreted on a yield-to-maturity basis.

Foreign currency translation The accounting records of the fund are maintained in U.S. dollars. The market value of foreign securities, currency holdings, and other assets and liabilities is recorded in the books and records of the fund after translation to U.S. dollars based on the exchange rates on that day. The cost of each security is determined using historical exchange rates. Income and withholding taxes are translated at prevailing exchange rates when earned or incurred. The fund does not isolate that portion of realized or unrealized gains or losses resulting from changes in the foreign exchange rate on investments from fluctuations arising from changes in the market prices of the securities. Such gains and losses are included with the net realized and unrealized gain or loss on investments. Net realized gains and losses on foreign currency transactions represent net realized exchange gains or losses on closed forward currency contracts, disposition of foreign currencies, currency gains and losses realized between the trade and settlement dates on securities transactions and the difference between the amount of investment income and foreign withholding taxes recorded on the fund’s books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized appreciation and depreciation of assets and liabilities in foreign currencies arise from changes in the value of open forward currency contracts and assets and liabilities other than investments at the period end, resulting from changes in the exchange rate.

Options contracts The fund uses options contracts to hedge against changes in values of securities it owns, owned or expects to own.

Voyager Fund  35 

The potential risk to the fund is that the change in value of options contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise from changes in the value of the underlying instruments, if there is an illiquid secondary market for the contracts, if interest or exchange rates move unexpectedly or if the counterparty to the contract is unable to perform. Realized gains and losses on purchased options are included in realized gains and losses on investment securities. If a written call option is exercised, the premium originally received is recorded as an addition to sales proceeds. If a written put option is exercised, the premium originally received is recorded as a reduction to the cost of investments.

Exchange traded options are valued at the last sale price or, if no sales are reported, the last bid price for purchased options and the last ask price for written options. OTC traded options are valued using prices supplied by dealers. Certain options contracts include premiums that do not settle until the expiration date of the contract.

Written option contracts outstanding at period end, if any, are listed after the fund’s portfolio. For the fund’s average contract amount, see Note 5.

Forward currency contracts The fund buys and sells forward currency contracts, which are agreements between two parties to buy and sell currencies at a set price on a future date. These contracts are used to hedge foreign exchange risk.

The U.S. dollar value of forward currency contracts is determined using current forward currency exchange rates supplied by a quotation service. The market value of the contract will fluctuate with changes in currency exchange rates. The contract is marked to market daily and the change in market value is recorded as an unrealized gain or loss. The fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed when the contract matures or by delivery of the currency. The fund could be exposed to risk if the value of the currency changes unfavorably, if the counterparties to the contracts are unable to meet the terms of their contracts or if the fund is unable to enter into a closing position. Risks may exceed amounts recognized on the Statement of assets and liabilities.

Forward currency contracts outstanding at period end, if any, are listed after the fund’s portfolio. For the fund’s average contract amount, see Note 5.

Total return swap contracts The fund entered into OTC total return swap contracts, which are arrangements to exchange a market linked return for a periodic payment, both based on a notional principal amount, to gain exposure to specific sectors or industries.

To the extent that the total return of the security, index or other financial measure underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the fund will receive a payment from or make a payment to the counterparty. OTC total return swap contracts are marked to market daily based upon quotations from an independent pricing service or market makers and the change, if any, is recorded as an unrealized gain or loss. Payments received or made are recorded as realized gains or losses. Certain OTC total return swap contracts may include extended effective dates. Payments related to these swap contracts are accrued based on the terms of the contract. The fund could be exposed to credit or market risk due to unfavorable changes in the fluctuation of interest rates or in the price of the underlying security or index, the possibility that there is no liquid market for these agreements or that the counterparty may default on its obligation to perform. The fund’s maximum risk of loss from counterparty risk is the fair value of the contract. This risk may be mitigated by having a master netting arrangement between the fund and the counterparty. Risk of loss may exceed amounts recognized on the Statement of assets and liabilities.

OTC total return swap contracts outstanding at period end, if any, are listed after the fund’s portfolio. For the fund’s average notional amount, see Note 5.

Master agreements The fund is a party to ISDA (International Swaps and Derivatives Association, Inc.) Master Agreements (Master Agreements) with certain counterparties that govern OTC derivative and foreign exchange contracts entered into from time to time. The Master Agreements may contain provisions regarding, among other things, the parties’ general obligations, representations, agreements, collateral requirements, events of default and early termination. With respect to certain counterparties, in accordance with the terms of the Master Agreements, collateral posted to the fund is held in a segregated account by the fund’s custodian and with respect to those amounts which can be sold or repledged, are presented in the fund’s portfolio. Collateral posted to the fund which cannot be sold or repledged totaled $2,869,463 at the close of the reporting period.

Collateral pledged by the fund is segregated by the fund’s custodian and identified in the fund’s portfolio. Collateral can be in the form of cash or debt securities issued by the U.S. Government or related agencies or other securities

36   Voyager Fund 

as agreed to by the fund and the applicable counterparty. Collateral requirements are determined based on the fund’s net position with each counterparty.

Termination events applicable to the fund may occur upon a decline in the fund’s net assets below a specified threshold over a certain period of time. Termination events applicable to counterparties may occur upon a decline in the counterparty’s long-term and short-term credit ratings below a specified level. In each case, upon occurrence, the other party may elect to terminate early and cause settlement of all derivative and foreign exchange contracts outstanding, including the payment of any losses and costs resulting from such early termination, as reasonably determined by the terminating party. Any decision by one or more of the fund’s counterparties to elect early termination could impact the fund’s future derivative activity.

At the close of the reporting period, the fund did not have a net liability position on derivative contracts subject to the Master Agreements.

Securities lending The fund may lend securities, through its agent, to qualified borrowers in order to earn additional income. The loans are collateralized by cash in an amount at least equal to the market value of the securities loaned. The market value of securities loaned is determined daily and any additional required collateral is allocated to the fund on the next business day. The risk of borrower default will be borne by the fund’s agent; the fund will bear the risk of loss with respect to the investment of the cash collateral. Income from securities lending is included in investment income on the Statement of operations. Cash collateral is invested in Putnam Cash Collateral Pool, LLC, a limited liability company managed by an affiliate of Putnam Management. Investments in Putnam Cash Collateral Pool, LLC are valued at its closing net asset value each business day. There are no management fees charged to Putnam Cash Collateral Pool, LLC. At the close of the reporting period, the value of securities loaned amounted to $388,361,738. Certain of these securities were sold prior to the close of the reporting period and are included in Receivable for investments sold on the Statement of assets and liabilities. The fund received cash collateral of $395,804,515.

Interfund lending The fund, along with other Putnam funds, may participate in an interfund lending program pursuant to an exemptive order issued by the SEC. This program allows the fund to borrow from or lend to other Putnam funds that permit such transactions. Interfund lending transactions are subject to each fund’s investment policies and borrowing and lending limits. Interest earned or paid on the interfund lending transaction will be based on the average of certain current market rates. During the reporting period, the fund did not utilize the program.

Line of credit The fund participates, along with other Putnam funds, in a $315 million unsecured committed line of credit and a $185 million unsecured uncommitted line of credit, both provided by State Street. Borrowings may be made for temporary or emergency purposes, including the funding of shareholder redemption requests and trade settlements. Interest is charged to the fund based on the fund’s borrowing at a rate equal to the Federal Funds rate plus 1.25% for the committed line of credit and the Federal Funds rate plus 1.30% for the uncommitted line of credit. A closing fee equal to 0.02% of the committed line of credit and $50,000 for the uncommitted line of credit has been paid by the participating funds. In addition, a commitment fee of 0.11% per annum on any unutilized portion of the committed line of credit is allocated to the participating funds based on their relative net assets and paid quarterly. During the reporting period, the fund had no borrowings against these arrangements.

Federal taxes It is the policy of the fund to distribute all of its taxable income within the prescribed time period and otherwise comply with the provisions of the Internal Revenue Code of 1986, as amended (the Code), applicable to regulated investment companies. It is also the intention of the fund to distribute an amount sufficient to avoid imposition of any excise tax under Section 4982 of the Code.

The fund is subject to the provisions of Accounting Standards Codification ASC 740 Income Taxes (ASC 740). ASC 740 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The fund did not have a liability to record for any unrecognized tax benefits in the accompanying financial statements. No provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains. Each of the fund’s federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

The fund may also be subject to taxes imposed by governments of countries in which it invests. Such taxes are generally based on either income or gains earned or repatriated. The fund accrues and applies such taxes to net investment income, net realized gains and net unrealized gains as income and/or capital gains are earned. In some cases, the fund may be entitled to reclaim all or a portion of such taxes, and such reclaim amounts, if any, are reflected as an asset on the fund’s books. In many cases, however, the fund may not receive such amounts for an extended period of time, depending on the country of investment.

Voyager Fund  37 

At July 31, 2012 the fund had a capital loss carryover of $414,288,774 available to the extent allowed by the Code to offset future net capital gain, if any. The amounts of the carryovers and the expiration dates are:

	Loss carryover
Short-term	Long-term	Total	Expiration
$115,108,326	$—	$115,108,326	*
299,180,448	N/A	299,180,448	July 31, 2017

* Under the Regulated Investment Company Modernization Act of 2010, the fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer certain capital losses of $120,184,889 recognized during the period between November 1, 2011 and July 31, 2012 to its fiscal year ending July 31, 2013.

The aggregate identified cost on a tax basis is $3,998,912,994, resulting in gross unrealized appreciation and depreciation of $318,399,229 and $277,692,883, respectively, or net unrealized appreciation of $40,706,346.

Distributions to shareholders Distributions to shareholders from net investment income are recorded by the fund on the ex-dividend date. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year. Reclassifications are made to the fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryovers) under income tax regulations.

Note 2: Management fee, administrative services and other transactions

The fund pays Putnam Management a management fee (base fee) (based on the fund’s average net assets and computed and paid monthly) at annual rates that may vary based on the average of the aggregate net assets of most open-end funds, as defined in the fund’s management contract, sponsored by Putnam Management. Such annual rates may vary as follows:

0.710%	of the first $5 billion,	0.510%	of the next $50 billion,
0.660%	of the next $5 billion,	0.490%	of the next $50 billion,
0.610%	of the next $10 billion,	0.480%	of the next $100 billion and
0.560%	of the next $10 billion,	0.475%	of any excess thereafter.

In addition, beginning with January 2011, the monthly management fee consists of the monthly base fee plus or minus a performance adjustment for the month. The performance adjustment is determined based on performance over the thirty-six month period then ended or, if shorter, the period from January 1, 2010 to the end of the month for which the fee adjustment is being computed. Each month, the performance adjustment is calculated by multiplying the performance adjustment rate and the fund’s average net assets over the performance period and the result is divided by twelve. The resulting dollar amount is added to, or subtracted from the base fee for that month. The performance adjustment rate is equal to 0.03 multiplied by the difference between the fund’s annualized performance (measured by the fund’s class A shares) and the annualized performance of the Russell 1000 Growth Index, each measured over the performance period. The maximum annualized performance adjustment rates are +/– 0.12%. The monthly base fee is determined based on the fund’s average net assets for the month, while the performance adjustment is determined based on the fund’s average net assets over the performance period of up to thirty-six months. This means it is possible that, if the fund underperforms significantly over the performance period, and the fund’s assets have declined significantly over that period, the negative performance adjustment may exceed the base fee. In this event, Putnam Management would make a payment to the fund.

38   Voyager Fund 

Because the performance adjustment is based on the fund’s performance relative to its applicable benchmark index, and not its absolute performance, the performance adjustment could increase Putnam Management’s fee even if the fund’s shares lose value during the performance period provided that the fund outperformed its benchmark index, and could decrease Putnam Management’s fee even if the fund’s shares increase in value during the performance period provided that the fund underperformed its benchmark index.

For the reporting period, the base fee represented an effective rate (excluding the impact from any expense waivers in effect) of 0.285% of the fund’s average net assets before a decrease of $2,446,013 (0.069% of the fund’s average net assets) based on performance.

Putnam Management has contractually agreed, through June 30, 2013, to waive fees or reimburse the fund’s expenses to the extent necessary to limit the cumulative expenses of the fund, exclusive of brokerage, interest, taxes, investment-related expenses, extraordinary expenses, acquired fund fees and expenses and payments under the fund’s investor servicing contract, investment management contract and distribution plans, on a fiscal year-to-date basis to an annual rate of 0.20% of the fund’s average net assets over such fiscal year-to-date period. During the reporting period, the fund’s expenses were not reduced as a result of this limit.

Putnam Investments Limited (PIL), an affiliate of Putnam Management, is authorized by the Trustees to manage a separate portion of the assets of the fund as determined by Putnam Management from time to time. Putnam Management pays a quarterly sub-management fee to PIL for its services at an annual rate of 0.35% of the average net assets of the portion of the fund managed by PIL.

The fund reimburses Putnam Management an allocated amount for the compensation and related expenses of certain officers of the fund and their staff who provide administrative services to the fund. The aggregate amount of all such reimbursements is determined annually by the Trustees.

Custodial functions for the fund’s assets are provided by State Street. Custody fees are based on the fund’s asset level, the number of its security holdings and transaction volumes.

Putnam Investor Services, Inc., an affiliate of Putnam Management, provides investor servicing agent functions to the fund. Putnam Investor Services, Inc. received fees for investor servicing (except for Class R5 and R6 shares) based on the fund’s retail asset level, the number of shareholder accounts in the fund and the level of defined contribution plan assets in the fund. Class R5 shares pay a monthly fee based on the average net assets of class R5 shares at an annual rate of 0.15%. Class R6 shares pay a monthly fee based on the average net assets of class R6 shares at an annual rate of 0.05%. Investor servicing fees will not exceed an annual rate of 0.32% of the fund’s average net assets. Prior to March 1, 2012, investor servicing fees could not exceed an annual rate of 0.375% of the fund’s average net assets. During the reporting period, the expenses for each class of shares related to investor servicing fees were as follows:

Class A	$4,278,646	Class R5	8
Class B	153,018	Class R6	3
Class C	227,179	Class Y	464,732
Class M	34,085	Total	$5,185,542
Class R	27,871

The fund has entered into expense offset arrangements with Putnam Investor Services, Inc. and State Street whereby Putnam Investor Services, Inc.’s and State Street’s fees are reduced by credits allowed on cash balances. The fund also reduced expenses through brokerage/service arrangements. For the reporting period, the fund’s expenses were reduced by $2,129 under the expense offset arrangements and by $404,364 under the brokerage/service arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of which $2,666 as a quarterly retainer, has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees also are reimbursed for expenses they incur relating to their services as Trustees.

The fund has adopted a Trustee Fee Deferral Plan (the Deferral Plan) which allows the Trustees to defer the receipt of all or a portion of Trustees fees payable on or after July 1, 1995. The deferred fees remain invested in certain Putnam funds until distribution in accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension plan (the Pension Plan) covering all Trustees of the fund who have served as a Trustee for at least five years and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee’s average annual attendance and retainer fees for

Note 7: Market, credit and other risks

In the normal course of business, the fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the contracting party to the transaction to perform (credit risk). The fund may be exposed to additional credit risk that an institution or other entity with which the fund has unsettled or open transactions will default. Investments in foreign securities involve certain risks, including those related to economic instability, unfavorable political developments, and currency fluctuations.

Note 8: New accounting pronouncement

In December 2011, the FASB issued ASU No. 2011–11 “Disclosures about Offsetting Assets and Liabilities”. The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of assets and liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. Putnam Management is currently evaluating the application of ASU 2011–11 and its impact, if any, on the fund’s financial statements.
