Putnam Investments Limited*

The Putnam Advisory Company, LLC*

On May 31, 2023, Franklin Resources, Inc. (“Franklin Resources”) and Great-West Lifeco Inc., the parent company of Putnam U.S. Holdings I, LLC (“Putnam Holdings”), announced that they have entered into a definitive agreement for a subsidiary of Franklin Resources to acquire Putnam Holdings in a stock and cash transaction.

As part of this transaction, Putnam Investment Management, LLC (“Putnam Management”), a wholly owned subsidiary of Putnam Holdings and investment manager to the Putnam family of funds (the “Putnam Funds”), including your fund, would become an indirect wholly owned subsidiary of Franklin Resources.

The transaction is subject to customary closing conditions, including receipt of applicable regulatory approvals. Subject to such approvals and the satisfaction of these conditions, the transaction is currently expected to be consummated in the fourth quarter of 2023 or early 2024.

Under the Investment Company Act of 1940, as amended, consummation of the transaction will result in the automatic termination of the investment management contract between each Putnam Fund and Putnam Management and any related sub-management and sub-advisory contracts, where applicable. In anticipation of this automatic termination, on June 23, 2023, the Board of Trustees of the Putnam Funds approved a new investment management contract between each Putnam Fund and Putnam Management (and new sub-management and sub-advisory contracts, if applicable), which were, or will be, presented to the shareholders of each Putnam Fund for their approval at shareholder meetings in October 2023 or at any adjourned sessions of such meetings. Proxy solicitation materials related to these meetings have been made available to shareholders that held shares of the fund at the close of business on July 24, 2023.

Purchase and sale of fund shares

You can open an account, purchase and/or sell fund shares, or exchange them for shares of another Putnam fund by contacting your financial professional or by calling Putnam Investor Services at 1-800-225-1581. Purchases of class B shares are closed to new and existing investors except by exchange from class B shares of another Putnam fund or through dividend and/or capital gains reinvestment.

When opening an account, you must complete and mail a Putnam account application, along with a check made payable to the fund, to: Putnam Investments, P.O. Box 219697, Kansas City, MO 64121-9697. The minimum initial investment of $500 is currently waived, although Putnam reserves the right to reject initial investments under $500 at its discretion. There is no minimum for subsequent investments.

You can sell your shares back to the fund or exchange them for shares of another Putnam fund any day the New York Stock Exchange (NYSE) is open. Shares may be sold or exchanged by mail, by phone, or, for exchanges only, online at putnam.com. Some restrictions may apply.

Tax information

The fund’s distributions will be taxed as ordinary income or capital gains unless you hold the shares through a tax-advantaged arrangement, in which case you will generally be taxed only upon withdrawal of monies from the arrangement.

Financial intermediary compensation

If you purchase the fund through a broker/dealer or other financial intermediary (such as a bank or financial professional), the fund and its related companies may pay that intermediary for the sale of fund shares and related services. Please bear in mind that these payments may create a conflict of interest by influencing the broker/dealer or other intermediary to recommend the fund over another investment. Ask your advisor or visit your advisor’s website for more information.

What are the fund’s main investment strategies and related risks?

This section contains greater detail on the fund’s main investment strategies and the related risks you would face as a fund shareholder. It is important to keep in mind that risk and reward generally go hand in hand; the higher the potential reward, the greater the risk.

As mentioned in the fund summary, we pursue the fund’s goal by investing mainly in equity securities (growth or value or both) of large and midsize companies.

The fund is “non-diversified,” which means it may invest a greater percentage of its assets in fewer issuers than a “diversified” fund. A fund that makes large investments in fewer issuers (as the fund currently does) is more vulnerable than a more broadly diversified fund to fluctuations in the values of the securities it holds.

The fund may hold sizeable percentages of its assets in cash or short-term instruments that can be used to pursue favorable investment opportunities. Large cash positions may dampen results, and may prevent the fund from achieving its goals.

For all of these reasons, an investment in the fund may fluctuate in value to a greater degree, and have a greater degree of risk, than a fund that does not employ these investment strategies.

• Common stocks. Common stock represents an ownership interest in a company. The value of a company’s stock may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company’s products or services. A stock’s value may also fall because of factors affecting not just the company, but also other companies in the same industry or in a number of different industries, such as increases in production costs. From time to time, the fund may invest a significant portion of its assets in companies in one or more related industries or sectors, which would make the fund more vulnerable to adverse developments affecting those industries or sectors. For example, the fund may invest a significant portion of its assets in companies in the information technology sector (including companies that develop products, processes or services that will provide advances and improvements through information technology to consumers, enterprises and governments). The information technology sector may be significantly affected by technological obsolescence or innovation, short product cycles, falling prices and profits, competitive pressures and general market conditions.

The value of a company’s stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates or inflation rates. In addition, a company’s stock generally pays dividends only after the company invests in its own business and makes required payments to holders of its bonds and other debt. For this reason, the value of a company’s stock will usually react more strongly than its bonds and other debt to actual or perceived changes in the company’s financial condition or prospects.

Growth stocks — Stocks of companies we believe are fast-growing may trade at a higher multiple of current earnings than other stocks. The values of these stocks may be more sensitive to changes in current or expected earnings or to heightened levels of inflation than the values of other stocks. If our assessment of the prospects for a company’s earnings growth is wrong, or if our judgment of how other investors will value the company’s earnings growth is wrong, then the price of the company’s stock may fall or may not approach the value that we have placed on it. In addition, growth stocks, at times, may not perform as well as value stocks or the stock market in general, and may be out of favor with investors for varying periods of time.

Value stocks — Companies whose stocks we believe are undervalued by the market may have experienced adverse business developments or may be subject to special risks that have caused their stocks to be out of favor. If our assessment of a company’s

prospects is wrong, or if other investors do not similarly recognize the value of the company, then the price of the company’s stock may fall or may not approach the value that we have placed on it. In addition, value stocks, at times, may not perform as well as growth stocks or the stock market in general, and may be out of favor with investors for varying periods of time.

• Small and midsize companies. These companies, some of which may have a market capitalization of less than $1 billion, are more likely than larger companies to have limited product lines, markets or financial resources, lack profitability or depend on a small management group. Stocks of these companies often trade in smaller volumes, and their prices may fluctuate more than stocks of larger companies. Stocks of small and midsize companies may therefore be more vulnerable to adverse developments than those of larger companies. In addition, stocks of small and midsize companies, at times, may not perform as well as stocks of larger companies or the stock market in general, and may be out of favor with investors for varying periods of time.

• Preferred stocks. Preferred stock generally pays dividends at a specified rate. Like common stock, the value of preferred stock may fluctuate in response to factors affecting the issuer, the issuer’s industry, and the financial markets generally. Preferred stock may also be subject to interest rate risk and other risks common to debt securities, and it ordinarily does not carry voting rights. Preferred stock has preference over common stock in the payment of dividends and the liquidation of assets, but it is junior to the debt securities of the issuer in those respects.

• Convertible securities. Convertible securities include bonds, preferred stocks and other instruments that pay interest or dividends and that can be converted into or exchanged for common stocks or other equity securities, or equivalent value, at a particular price or rate (a “conversion price”). Convertible securities generally have less potential for gain or loss than common stocks, but may have more potential for gain or loss than debt securities. In general, a convertible security performs more like a stock when the underlying stock’s price is near or higher than the conversion price (because it is assumed that it will be converted into the stock) and more like a bond when the underlying stock’s price is lower than the conversion price (because it is assumed that it will not be converted). Convertible securities tend to provide higher yields than common stocks. However, a higher yield may not protect investors against the risk of loss or adequately mitigate any loss associated with a decline in the price of a convertible security.

• Foreign investments. We may invest in foreign investments, although they do not represent a primary focus of the fund. Foreign investments involve certain special risks. For example, their values may decline in response to changes in currency exchange rates, unfavorable political and legal developments, unreliable or untimely information, and economic and financial instability. In addition, the liquidity of these investments may be more limited than for most U.S. investments, which means we may at times be unable to sell them at desirable prices. Foreign settlement procedures may also involve additional risks. These risks are generally greater in the case of developing (also known as emerging) markets, which typically have less developed legal and financial systems.

Some of these risks may also apply to some extent to U.S.-traded investments that are denominated in foreign currencies, investments in U.S. companies that are traded in foreign markets, or investments in U.S. companies that have significant foreign operations.

• Depositary receipts. We may invest in American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs), which represent interests in a company’s securities that have been deposited with a bank or trust and that trade on an exchange or over-the-counter (OTC). For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. entity. For GDRs, the depository may be a U.S. or non-U.S. entity and the underlying securities may be issued by a U.S. or non-U.S. entity. Although the issuing bank or trust company may impose charges for the collection of dividends and the conversion of such securities into the underlying securities, there are generally no fees imposed on the purchase or sale of these securities, other than transaction fees ordinarily involved with trading stock. Such securities may be less liquid or may trade at lower prices than the underlying securities of the issuer. Additionally, the issuers of securities underlying depositary receipts may not be obligated to timely disclose information that is considered material under the securities laws of the United States. Therefore, less information may be available regarding these issuers than about the issuers of other securities and the market value of the depositary receipts may only reflect such limited information.

• Derivatives. We may engage in a variety of transactions involving equity-related derivatives, such as futures, options, certain foreign currency transactions and swap contracts, although they do not represent a primary focus of the fund. Derivatives are financial instruments whose value depends upon, or is derived from, the value of something else, such as one or more underlying investments, pools of investments, indexes or currencies. We may make use of “short” derivative positions, the values of which typically move in the opposite direction from the price of the underlying investment, pool of investments, index or currency. We may use derivatives both for hedging and non-hedging purposes, including as a substitute for a direct investment in the securities of one or more issuers. For example, we may, from time to time, write (i.e., sell) covered call options or purchase put options on securities to hedge against declines in the value of securities in the fund’s portfolio. We may use foreign currency transactions to increase or decrease the fund’s exposure to a particular currency or group of currencies. We may also invest in index futures contracts as a substitute for a direct investment in securities. However, we may also choose not to use derivatives based on our evaluation of market conditions or the availability of suitable derivatives. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to that investment.

Derivatives involve special risks and may result in losses. The successful use of derivatives depends on our ability to manage these sophisticated instruments. Some derivatives are “leveraged,” which means they provide the fund with investment exposure greater than the value of the fund’s investment in the derivatives. As a result,

these derivatives may magnify or otherwise increase investment losses to the fund. The risk of loss from certain short derivative positions is theoretically unlimited. The value of derivatives may move in unexpected ways due to unanticipated market movements, the use of leverage, imperfect correlation between the derivative instrument and the reference asset, or other factors, especially in unusual market conditions, and volatility in the value of derivatives could adversely impact the fund’s returns, obligations and exposures.

Other risks arise from the potential inability to terminate or sell derivative positions. Derivatives may be subject to liquidity risk due to the fund’s obligation to make payments of margin, collateral, or settlement payments to counterparties. A liquid secondary market may not always exist for the fund’s derivative positions. In fact, certain over-the-counter instruments (investments not traded on an exchange) may not be liquid. Over-the-counter instruments also involve the risk that the other party to the derivative transaction may not be willing or able to meet its obligations with respect to the derivative transaction. The risk of a party failing to meet its obligations may increase if the fund has significant exposure to that counterparty. Derivative transactions may also be subject to operational risk, including due to documentation and settlement issues, system failures, inadequate controls and human error, and legal risk due to insufficient documentation, insufficient capacity or authority of a counterparty, or issues with respect to the legality or enforceability of the derivative contract. For further information about additional types and risks of derivatives, see Miscellaneous Investments, Investment Practices and Risks in the SAI.

• Liquidity and illiquid investments. We may invest up to 15% of the fund’s net assets in illiquid investments, which may be considered speculative and which may be difficult to sell. The sale of many of these investments is prohibited or limited by law or contract. Some investments may be difficult to value for purposes of determining the fund’s net asset value. Certain other investments may not have an active trading market due to adverse market, economic, industry, political, regulatory, geopolitical, environmental, public health, and other conditions, including investors trying to sell large quantities of a particular investment or type of investment, or lack of market makers or other buyers for a particular investment or type of investment. We may not be able to sell the fund’s illiquid investments when we consider it desirable to do so, or we may be able to sell them only at less than their value. The larger size of certain of a fund’s holdings and the lack of liquidity in securities markets may limit our ability to sell those securities, or to sell them at appropriate prices, thereby negatively impacting the fund.

• Market risk. The value of investments in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic, political or financial market conditions; investor sentiment and market perceptions (including perceptions about monetary policy, interest rates, inflation or the risk of default); government actions (including protectionist measures, intervention in the financial markets or other regulation, and changes in fiscal, monetary or tax policies); geopolitical events or changes (including natural disasters, terrorism and war); outbreaks of infectious illnesses or other widespread public health issues (including

epidemics and pandemics); and factors related to a specific issuer, geography, industry or sector. Foreign financial markets have their own market risks, and they may be more or less volatile than U.S. markets and may move in different directions. During a general downturn in financial markets, multiple asset classes may decline in value simultaneously. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings. During those periods, the fund may experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices. These risks may be exacerbated during economic downturns or other periods of economic stress.

The COVID-19 pandemic and efforts to contain its spread have resulted in, among other effects, significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, significant changes in fiscal and monetary policies, and economic downturns and recessions. The effects of the COVID-19 pandemic have negatively affected, and may continue to negatively affect, the global economy, the economies of the United States and other individual countries, the financial performance of individual issuers, sectors, industries, asset classes, and markets, and the value, volatility, and liquidity of particular securities and other assets. The effects of the COVID-19 pandemic also are likely to exacerbate other risks that apply to the fund, including the risks disclosed in this prospectus, which could negatively impact the fund’s performance and lead to losses on your investment in the fund. The duration of the COVID-19 pandemic and its effects cannot be determined with certainty.

• ESG considerations. We expect to integrate environmental, social, or governance (“ESG”) considerations, where we consider them material and relevant, into our fundamental research process and investment decision-making for the fund, although ESG considerations do not represent a primary focus of the fund. We believe that ESG considerations, like other, more traditional subjects of investment analysis such as market position, growth prospects, and business strategy, have the potential to impact financial risk and investment returns. We believe that ESG considerations are best analyzed in combination with a company’s fundamentals, including a company’s industry, geography, and strategic position. When considering ESG factors, we use company disclosures, public data sources, and independent third-party data as inputs into our analytical processes. The consideration of ESG factors as part of the fund’s investment process does not mean that the fund pursues a specific “ESG” or “sustainable” investment strategy, and we may make investment decisions for the fund other than on the basis of relevant ESG considerations.

• Management and operational risk. The fund is actively managed and its performance will reflect, in part, our ability to make investment decisions that seek to achieve the fund’s investment objective. There is no guarantee that the investment techniques, analyses, or judgments that we apply in making investment decisions for the fund will produce the intended outcome or that the investments we select for the fund will perform as well as other securities that were not selected for the fund. As a result, the fund may underperform its benchmark or other funds with a similar investment goal and may realize losses. In addition, we, or the fund’s other service

providers, may experience disruptions or operating errors that could negatively impact the fund. Although service providers may have operational risk management policies and procedures and take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors, it may not be possible to identify all of the operational risks that may affect the fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

• Other investments. In addition to the main investment strategies described above, the fund may make other types of investments, such as investments in convertible securities and debt instruments. The fund may also invest in cash or cash equivalents, including money market instruments or short-term instruments such as commercial paper, bank obligations (e.g., certificates of deposit and bankers’ acceptances), repurchase agreements, and U.S. Treasury bills or other government obligations. The fund may also from time to time invest all or a portion of its cash balances in money market and/or short-term bond funds advised by Putnam Management or its affiliates. The percentage of the fund invested in cash and cash equivalents and such money market and short-term bond funds is expected to vary over time and will depend on various factors, including market conditions, purchase and redemption activity by fund shareholders, and our assessment of the cash level that is appropriate to allow the fund to pursue investment opportunities as they arise and to meet shareholder redemption requests. Large cash positions may dampen performance and may prevent the fund from achieving its goal. The fund may also loan portfolio securities to earn income. These practices may be subject to other risks, as described under Miscellaneous Investments, Investment Practices and Risks in the SAI.

• Temporary defensive strategies. In response to adverse market, economic, political or other conditions, we may take temporary defensive positions, such as investing some or all of the fund’s assets in cash and cash equivalents, that differ from the fund’s usual investment strategies. However, we may choose not to use these temporary defensive strategies for a variety of reasons, even in very volatile market conditions. If we do employ these strategies, the fund may miss out on investment opportunities, and may not achieve its goal. Additionally, while temporary defensive strategies are mainly designed to limit losses, they may not work as intended.

• Changes in policies. The Trustees may change the fund’s goal, investment strategies and other policies set forth in this prospectus without shareholder approval, except as otherwise provided in the prospectus or SAI.

• Portfolio turnover rate. The fund’s portfolio turnover rate measures how frequently the fund buys and sells investments. A portfolio turnover rate of 100%, for example, would mean that the fund sold and replaced securities valued at 100% of the fund’s assets within a one-year period. From time to time the fund may engage in frequent trading. Funds with high turnover may be more likely to realize capital gains that must be distributed to shareholders as taxable income. High turnover may also cause a fund to pay more brokerage commissions and other transaction costs, which may detract from performance. The fund’s portfolio turnover rate and the amount of brokerage commissions it pays will vary over time based on market conditions.

• Portfolio holdings. The SAI includes a description of the fund’s policies with respect to the disclosure of its portfolio holdings. For more specific information on the fund’s portfolio, you may visit the Putnam Investments website, putnam.com/individual, where the fund’s top 10 holdings and related portfolio information may be viewed monthly beginning approximately 15 days after the end of each month, and full portfolio holdings may be viewed quarterly beginning on the 8th business day after the end of each calendar quarter. This information will remain available on the website at least until the fund files a Form N-CSR or publicly available Form N-PORT with the SEC for the period that includes the date of the information, after which such information can be found on the SEC’s website at http://www.sec.gov.

Who oversees and manages the fund?

The fund’s Trustees

As a shareholder of a mutual fund, you have certain rights and protections, including representation by a Board of Trustees. The Putnam Funds’ Board of Trustees oversees the general conduct of the fund’s business and represents the interests of the Putnam fund shareholders. At least 75% of the members of the Putnam Funds’ Board of Trustees are independent, which means they are not officers of the fund or affiliated with Putnam Investment Management, LLC (Putnam Management).

The Trustees periodically review the fund’s investment performance and the quality of other services such as administration, custody, and investor services. At least annually, the Trustees review the fees paid to Putnam Management and its affiliates for providing or overseeing these services, as well as the overall level of the fund’s operating expenses. In carrying out their responsibilities, the Trustees are assisted by an administrative staff, auditors and legal counsel that are selected by the Trustees and are independent of Putnam Management and its affiliates.

The fund’s investment manager

The Trustees have retained Putnam Management, which has managed mutual funds since 1937, to be the fund’s investment manager, responsible for making investment decisions for the fund and managing the fund’s other affairs and business.

The basis for the Trustees’ approval of the fund’s management contract and the sub-management and sub-advisory contracts described below is discussed in the fund’s annual report to shareholders dated August 31, 2023.

The fund pays a monthly management fee to Putnam Management. The fee is calculated by applying a rate to the fund’s average net assets for the month. The rate is based on the monthly average of the aggregate net assets of other open-end funds sponsored by Putnam Management (excluding net assets of such funds that are invested in, or that are invested in by, other such funds to the extent necessary to avoid “double counting” of those assets), and generally declines as the aggregate net assets increase.

The fund paid Putnam Management a management fee (after any applicable waivers) of 0.62% of average net assets for the fund’s last fiscal year.

Putnam Management’s address is 100 Federal Street, Boston, MA 02110.

Putnam Management has retained its affiliate PIL to make investment decisions for such fund assets as may be designated from time to time for its management by Putnam Management. PIL is not currently managing any fund assets. If PIL were to manage any fund assets, Putnam Management (and not the fund) would pay a quarterly sub-management fee to PIL for its services at the annual rate of 0.25% of the average net asset value (NAV) of any fund assets managed by PIL. PIL, which provides a full range of international investment advisory services to institutional clients, is located at 16 St James’s Street, London, England, SW1A 1ER.

Putnam Management and PIL have retained their affiliate PAC to make investment decisions for such fund assets as may be designated from time to time for its management by Putnam Management. PAC is not currently managing any fund assets. If PAC were to manage any fund assets, Putnam Management or PIL, as applicable (and not the fund), would pay a quarterly sub-advisory fee to PAC for its services at the annual rate of 0.25% of the average NAV of any fund assets managed by PAC. PAC, which provides financial services to institutions and individuals through separately-managed accounts and pooled investment vehicles, has its headquarters at 100 Federal Street, Boston, MA 02110, with additional investment management personnel located in Singapore.

Pursuant to these arrangements, Putnam investment professionals who are based in foreign jurisdictions may serve as portfolio managers of the fund or provide other investment services, consistent with local regulations.

• Portfolio managers. The officers of Putnam Management identified below are jointly and primarily responsible for the day-to-day management of the fund’s portfolio.

The SAI provides information about these individuals’ compensation, other accounts managed by these individuals and these individuals’ ownership of securities in the fund.

How does the fund price its shares?

The price of the fund’s shares is based on its NAV. The NAV per share of each class equals the total value of its assets, less its liabilities, divided by the number of its outstanding shares. Shares are only valued as of the scheduled close of regular trading on the NYSE each day the exchange is open.

The fund values its investments for which market quotations are readily available at market value. It values all other investments and assets at their fair value, which may differ from recent market prices. For example, the fund may value a stock traded on a U.S. exchange at its fair value when the exchange closes early or trading in the stock is suspended. It may also value a stock at fair value if recent transactions in the stock have been very limited or if, in the case of a security traded on a market that closes before the NYSE closes, material information about the issuer becomes available after the close of the relevant market.

The fund translates prices for its investments quoted in foreign currencies into U.S. dollars at current exchange rates, which are generally determined as of 4:00 p.m. Eastern Time each day the NYSE is open. As a result, changes in the value of those currencies in relation to the U.S. dollar may affect the fund’s NAV. Because foreign markets may be open at different times than the NYSE, the value of the fund’s shares may change on days when shareholders are not able to buy or sell them.

Many securities markets and exchanges outside the U.S. close before the close of the NYSE, and the closing prices for securities in those markets or exchanges may not reflect events that occur after the close but before the scheduled close of regular trading on the NYSE. As a result, the fund has adopted fair value pricing procedures, which, among other things, require the fund to fair value foreign equity securities if there has been a movement in the U.S. market that exceeds a specified threshold that may change from time to time. As noted above, the value determined for an investment using the fund’s fair value pricing procedures may differ from recent market prices for the investment. Although the threshold may be revised from time to time and the number of days on which the fair value prices will be used will depend on market activity, it is possible that fair value prices will be used by the fund to a significant extent. As noted above, the value determined for an investment using the fund’s fair value pricing procedures may differ from recent market prices for the investment.

The fund’s most recent NAV is available on Putnam Investments’ website at putnam.com/individual or by contacting Putnam Investor Services at 1-800-225-1581.

How do I buy fund shares?

Opening an account

You can open a fund account and purchase class A, B and C shares by contacting your financial representative or Putnam Investor Services at 1-800-225-1581 and obtaining a Putnam account application. Purchases of class B shares are closed to new and existing investors except by exchange from class B shares of another Putnam fund or through dividend and/or capital gains reinvestment. The completed application, along with a check made payable to the fund, must then be returned to Putnam Investor Services at the following address:

Putnam Investments
P.O. Box 219697
Kansas City, MO 64121-9697

You can open a fund account with as little as $500. The minimum investment is waived if you make regular investments weekly, semi-monthly or monthly through automatic deductions from your bank checking or savings account. Although Putnam is currently waiving the minimum, it reserves the right to reject initial investments under the minimum at its discretion.

The fund sells its shares at the offering price, which is the NAV plus any applicable sales charge (class A shares only). Your financial representative or Putnam Investor Services generally must receive your completed buy order before the close of regular trading on the NYSE for your shares to be bought at that day’s offering price.

If you participate in an employer-sponsored retirement plan that offers the fund, please consult your employer for information on how to purchase shares of the fund through the plan, including any restrictions or limitations that may apply.

Federal law requires mutual funds to obtain, verify, and record information that identifies investors opening new accounts. Investors must provide their full name, residential or business address, Social Security or tax identification number, and date of birth. Entities, such as trusts, estates, corporations and partnerships must also provide additional identifying documentation. For trusts, the fund must obtain and verify identifying information for each trustee listed in the account registration. For certain legal entities, the fund must also obtain and verify identifying information regarding beneficial owners and/or control persons. The fund is unable to accept new accounts if any required information is not provided. If Putnam Investor Services cannot verify identifying information after opening your account, the fund reserves the right to close your account at the then-current NAV, which may be more or less than your original investment, net of any applicable sales charges. Putnam Investor Services may share identifying information with third parties for the purpose of verification subject to the terms of Putnam’s privacy policy.

Also, the fund may periodically close to new purchases of shares or refuse any order to buy shares if the fund determines that doing so would be in the best interests of the fund and its shareholders.

Purchasing additional shares

Once you have an existing account, you can make additional investments at any time in any amount in the following ways:

• Through a financial representative. Your representative will be responsible for furnishing all necessary documents to Putnam Investor Services and may charge you for his or her services.

• Through Putnam’s Systematic Investing Program. You can make regular investments weekly, semi-monthly or monthly through automatic deductions from your bank checking or savings account.

• Via the Internet or phone. If you have an existing Putnam fund account and you have completed and returned an Electronic Investment Authorization Form, you can buy additional shares online at putnam.com or by calling Putnam Investor Services at 1-800-225-1581.

• By mail. You may also request a book of investment stubs for your account. Complete an investment stub and write a check for the amount you wish to invest, payable to the fund. Return the check and investment stub to Putnam Investor Services.

• By wire transfer. You may buy fund shares by bank wire transfer of same-day funds. Please call Putnam Investor Services at 1-800-225-1581 for wiring instructions. Any commercial bank can transfer same-day funds by wire. The fund will normally accept wired funds for investment on the day received if they are received by the fund’s designated bank before the close of regular trading on the NYSE. Your bank may charge you for wiring same-day funds. Although the fund’s designated bank does not currently charge you for receiving same-day funds, it reserves the right to charge for this service. You cannot buy shares for employer-sponsored retirement plans by wire transfer.

Which class of shares is best for me?

This prospectus offers you three classes of fund shares: A, B and C. Employer-sponsored retirement plans may also choose class R or R6 shares, and certain investors described below may also choose class Y or R6 shares. Purchases of class B shares are closed to new and existing investors except by exchange from class B shares of another Putnam fund or through dividend and/or capital gains reinvestment.

Each share class represents investments in the same portfolio of securities, but each class has its own sales charge and expense structure, as illustrated in the Fund summary — Fees and expenses section, allowing you and your financial representative to choose the class that best suits your investment needs. When you purchase shares of the fund, you must choose a share class. Deciding which share class best suits your situation depends on a number of factors that you should discuss with your financial representative, including:

• How long you expect to hold your investment. Class B shares charge a contingent deferred sales charge (CDSC) on redemptions that is phased out over the first six years; class C shares charge a CDSC on redemptions in the first year.

• How much you intend to invest. While investments of less than $100,000 can be made in any share class, class A offers sales charge discounts starting at $50,000.

• Total expenses associated with each share class. As shown in the section entitled Fund summary — Fees and expenses, each share class offers a different combination of up-front and ongoing expenses. Generally, the lower the up-front sales charge, the greater the ongoing expenses.

Here is a summary of the differences among the classes of shares

Class A shares

• Initial sales charge of up to 5.75%

• Lower sales charges available for investments of $50,000 or more

• No deferred sales charge (except that a deferred sales charge of 1.00% may be imposed on certain redemptions of shares bought without an initial sales charge)

• Lower annual expenses, and higher dividends, than class B or C shares because of lower 12b-1 fees.

Class B shares

• Purchases of class B shares are closed to new and existing investors except by exchange from class B shares of another Putnam fund or through dividend and/or capital gains reinvestment

• No initial sales charge; your entire investment goes to work immediately

• Deferred sales charge of up to 5.00% if shares are sold within six years of purchase

• Higher annual expenses, and lower dividends, than class A shares because of higher 12b-1 fees

• Convert automatically to class A shares after eight years, thereby reducing future 12b-1 fees.

Class C shares

• No initial sales charge; your entire investment goes to work immediately

• Deferred sales charge of 1.00% if shares are sold within one year of purchase

• Higher annual expenses, and lower dividends, than class A shares because of higher 12b-1 fees

• Convert automatically to class A shares after eight years, thereby reducing future 12b-1 fees, provided that Putnam Investor Services or the financial intermediary through which a shareholder purchased class C shares has records verifying that the class C shares have been held for at least eight years, and that class A shares are available for purchase by residents in the shareholder’s jurisdiction. In certain cases, records verifying that the class C shares have been held for at least eight years may not be available (for example, participant level share lot aging may not be tracked by group retirement plan recordkeeping platforms through which class C shares of the fund are held in an omnibus account). If such records are unavailable, Putnam Investor Services or the relevant financial intermediary may not effect the conversion or may effect the conversion on a different schedule determined by Putnam Investor

Services or the financial intermediary, which may be shorter or longer than eight years. Investors should consult their financial representative for more information about their eligibility for class C share conversion.

• Orders for class C shares of one or more Putnam funds, other than class C shares sold to employer-sponsored retirement plans, will be refused when the total value of the purchase, plus existing account balances that are eligible to be linked under a right of accumulation for purchases of class A shares (as described below), is $1,000,000 or more. Investors considering cumulative purchases of $1,000,000 or more should consider whether class A shares would be more advantageous and consult their financial representative.

• May be exchanged automatically for class A shares if the shareholder is investing through an account or platform with a financial intermediary, to the extent described in the Appendix, provided that class A shares are available for purchase by residents in the shareholder’s jurisdiction.

Class R shares (available only to employer-sponsored retirement plans)

• No initial sales charge; your entire investment goes to work immediately

• No deferred sales charge

• Lower annual expenses, and higher dividends, than class B or C shares because of lower 12b-1 fees

• Higher annual expenses, and lower dividends, than class A shares because of higher 12b-1 fees

• No conversion to class A shares, so no reduction in future 12b-1 fees.

Class R6 shares (available only to investors listed below)

• The following investors may purchase class R6 shares:

• No initial sales charge; your entire investment goes to work immediately

• No deferred sales charge

• Lower annual expenses, and higher dividends, than class A, B, C or R shares because of no 12b-1 fees and lower investor servicing fees

• Lower annual expenses, and higher dividends, than class Y shares because of lower investor servicing fees.

Class Y shares (available only to investors listed below)

• The following investors may purchase class Y shares if approved by Putnam:

Insurance Company, or the fund’s Board of Trustees, the member’s class Y shares convert automatically to class A shares, unless the member’s departure is a retirement, as determined by Putnam in its discretion for employees and directors of Putnam and employees of Great-West Life & Annuity Insurance Company and by the Board of Trustees in its discretion for Trustees; provided that conversion will not take place with respect to class Y shares held by former Putnam employees and their immediate family members in health savings accounts where it is not operationally practicable due to platform or other limitations; and

Trust companies or bank trust departments that purchased class Y shares for trust accounts may transfer them to the beneficiaries of the trust accounts, who may continue to hold them or exchange them for class Y shares of other Putnam funds. Defined contribution plans (including corporate IRAs) that purchased class Y shares under prior eligibility criteria may continue to purchase class Y shares.

• No initial sales charge; your entire investment goes to work immediately

• No deferred sales charge

• Lower annual expenses, and higher dividends, than class A, B, C or R shares because of no 12b-1 fees

• Higher annual expenses, and lower dividends, than class R6 shares because of higher investor servicing fees.

Initial sales charges for class A shares

Reducing your class A sales charge

The fund offers two principal ways for you to qualify for discounts on initial sales charges on class A shares, often referred to as “breakpoint discounts”:

• Right of accumulation. You can add the amount of your current purchases of class A shares of the fund and other Putnam funds to the value of your existing accounts in the fund and other Putnam funds. Individuals can also include purchases by, and accounts owned by, their spouse and minor children, including accounts established through different financial representatives. For your current purchases, you will pay the initial sales charge applicable to the total value of the linked accounts and purchases, which may be lower than the sales charge otherwise applicable to each of your current purchases. Shares of Putnam money market funds, other than money market fund shares acquired by exchange from other Putnam funds, are not included for purposes of the right of accumulation.

To calculate the total value of your existing accounts and any linked accounts, the fund will use the higher of (a) the current maximum public offering price of those shares or (b) if you purchased the shares after December 31, 2007, the initial value of the total purchases, or, if you held the shares on December 31, 2007, the market value at maximum public offering price on that date, in either case, less the market value on the applicable redemption date of any of those shares that you have redeemed.

• Statement of intention. A statement of intention is a document in which you agree to make purchases of class A shares in a specified amount within a period of 13 months. For each purchase you make under the statement of intention, you will pay the initial sales charge applicable to the total amount you have agreed to purchase. While a statement of intention is not a binding obligation on you, if you do not purchase the full amount of shares within 13 months, the fund will redeem shares from your account in an amount equal to the difference between the higher initial sales charge you would have paid in the absence of the statement of intention and the initial sales charge you actually paid.

Account types that may be linked with each other to obtain breakpoint discounts using the methods described above include:

• Individual accounts

• Joint accounts

• Accounts established as part of a retirement plan and IRA accounts (some restrictions may apply)

• Shares of Putnam funds owned through accounts in the name of your dealer or other financial intermediary (with documentation identifying beneficial ownership of shares)

• Accounts held as part of a Section 529 college savings plan managed by Putnam Management (some restrictions may apply)

In order to obtain a breakpoint discount, you should inform your financial representative at the time you purchase shares of the existence of other accounts or purchases that are eligible to be linked for the purpose of calculating the initial sales

charge. The fund or your financial representative may ask you for records or other information about other shares held in your accounts and linked accounts, including accounts opened with a different financial representative. Restrictions may apply to certain accounts and transactions. Further details about breakpoint discounts can be found on Putnam Investments’ website at putnam.com/individual by selecting Pricing and performance from the Products drop-down menu, and then About fund costs, and in the SAI.

• Additional reductions and waivers of sales charges. In addition to the breakpoint discount methods described above for class A shares, the fund may sell the classes of shares specified below without a sales charge or CDSC under the circumstances described below. The sales charge and CDSC waiver categories described below do not apply to customers purchasing shares of the fund through any of the financial intermediaries specified in the Appendix to this prospectus (each, a “Specified Intermediary”).

Different financial intermediaries may impose different sales charges. Please refer to the Appendix for the sales charge or CDSC waivers that are applicable to each Specified Intermediary.

Class A shares

The following categories of investors are eligible to purchase class A shares without payment of a sales charge:

Administrators and other service providers of employer-sponsored retirement plans are required to enter into contractual arrangements with Putnam Investor Services in order to offer and hold fund shares. Administrators and other service providers of employer-sponsored retirement plans seeking to place trades on behalf of their plan clients should consult Putnam Investor Services as to the applicable requirements.

Class A, Class B and Class C shares

A CDSC is waived in the event of a redemption under the following circumstances:

Additional information about reductions and waivers of sales charges, including deferred sales charges, is included in the SAI. You may consult your financial representative or Putnam Retail Management for assistance.

How do I sell or exchange fund shares?

You can sell your shares back to the fund or exchange them for shares of another Putnam fund any day the NYSE is open, either through your financial representative or directly to the fund.

If you redeem your shares shortly after purchasing them, your redemption payment for the shares may be delayed until the fund collects the purchase price of the shares, which may be up to 7 calendar days after the purchase date.

Regarding exchanges, not all Putnam funds offer all classes of shares or may be open to new investors. If you exchange shares otherwise subject to a deferred sales charge, the transaction will not be subject to the deferred sales charge. When you redeem the shares acquired through the exchange, however, the redemption may be subject to the deferred sales charge, depending upon when and from which fund you originally purchased the shares. The deferred sales charge will be computed using the schedule of any fund into or from which you have exchanged your shares that would result in your paying the highest deferred sales charge applicable to your class of shares. For purposes of computing the deferred sales charge, the length of time you have owned your shares will be measured from the date of original purchase, unless you originally purchased the shares from another Putnam fund that does not directly charge a deferred sales charge, in which case the length of time you have owned your shares will be measured from the date you exchange those shares for shares of another Putnam fund that does charge a deferred sales charge, and will not be affected by any subsequent exchanges among funds.

• Selling or exchanging shares through your financial representative. Your representative must receive your request in proper form before the close of regular trading on the NYSE for you to receive that day’s NAV, less any applicable deferred sales charge. Your representative will be responsible for furnishing all necessary documents to Putnam Investor Services on a timely basis and may charge you for his or her services.

• Selling or exchanging shares directly with the fund. Putnam Investor Services must receive your request in proper form before the close of regular trading on the NYSE in order to receive that day’s NAV, less any applicable deferred sales charge.

• By mail. Send a letter of instruction signed by all registered owners or their legal representatives to Putnam Investor Services. If you have certificates for the shares you want to sell or exchange, you must return them unendorsed with your letter of instruction.

• By telephone. You may use Putnam’s telephone redemption privilege to redeem shares valued at less than $100,000 unless you have notified Putnam Investor Services of an address change within the preceding 15 days, in which case other requirements may apply. Unless you indicate otherwise on the account application, Putnam Investor Services will be authorized to accept redemption instructions received by telephone. A telephone exchange privilege is currently available. Sale or exchange of shares by telephone is not permitted if there are certificates for your shares. The telephone redemption and exchange privileges may be modified or terminated without notice.

• Via the Internet. You may also exchange shares via the Internet at putnam.com/individual.

• Shares held through your employer’s retirement plan. For information on how to sell or exchange shares of the fund that were purchased through your employer’s retirement plan, including any restrictions and charges that the plan may impose, please consult your employer.

• Additional requirements. In certain situations, for example, if you sell shares with a value of $100,000 or more, the signatures of all registered owners or their legal representatives must be guaranteed by a bank, broker-dealer or certain other financial institutions. In addition, Putnam Investor Services usually requires additional documents for the sale of shares by a corporation, partnership, agent or fiduciary, or surviving joint owner. For more information concerning Putnam’s signature guarantee and documentation requirements, contact Putnam Investor Services.

The fund also reserves the right to revise or terminate the exchange privilege, limit the amount or number of exchanges or reject any exchange. The fund into which you would like to exchange may also reject your exchange. These actions may apply to all shareholders or only to those shareholders whose exchanges Putnam Management determines are likely to have a negative effect on the fund or other Putnam funds. Consult Putnam Investor Services before requesting an exchange. Ask your financial representative or Putnam Investor Services for prospectuses of other Putnam funds. Some Putnam funds are not available in all states.

Deferred sales charges for class B, class C and certain class A shares

If you sell (redeem) class B shares within six years of purchase, you will generally pay a deferred sales charge according to the following schedule:

A deferred sales charge of 1.00% will apply to class C shares if redeemed within one year of purchase. Class A shares that are part of a purchase of $1 million or more (other than by an employer-sponsored retirement plan) will be subject to a 1.00% deferred sales charge if redeemed within twelve months of purchase.

Deferred sales charges will be based on the lower of the shares’ cost and current NAV. Shares not subject to any charge will be redeemed first, followed by shares held longest. You may sell shares acquired by reinvestment of distributions without a charge at any time.

• Payment information. If your account is held directly with Putnam Investor Services, the fund typically expects to send you payment for your shares the business day after your request is received in good order. If you hold your shares through certain financial intermediaries or financial intermediary programs, receipt of payment for your shares may differ based on industry standard trade settlement practices, as managed by your intermediary. However, it is possible that payment of redemption proceeds, for both accounts held with Putnam Investor Services and those held through a financial intermediary, may take up to seven days. Under unusual circumstances, the fund may suspend redemptions, or postpone payment for

more than seven days, as permitted by federal securities law. Under normal market conditions, the fund typically expects to satisfy redemption requests by using holdings of cash and cash equivalents or selling portfolio assets to generate cash. Under stressed market conditions, the fund may also satisfy redemption requests by borrowing under the fund’s lines of credit or interfund lending arrangements. For additional information regarding the fund’s lines of credit and interfund lending arrangements, please see the SAI.

To the extent consistent with applicable laws and regulations, the fund reserves the right to satisfy all or a portion of a redemption request by distributing securities or other property in lieu of cash (“in-kind” redemptions), under both normal and stressed market conditions. The fund generally expects to use in-kind redemptions only in stressed market conditions or stressed conditions specific to the fund, such as redemption requests that represent a large percentage of the fund’s net assets in order to minimize the effect of the large redemption on the fund and its remaining shareholders. The fund will not use in-kind redemptions for retail investors who hold shares of the fund through a financial intermediary. Any in-kind redemption will be effected through a pro rata distribution of all publicly traded portfolio securities or securities for which quoted bid prices are available, subject to certain exceptions. The securities distributed in an in-kind redemption will be valued in the same manner as they are valued for purposes of computing the fund’s net asset value. Once distributed in-kind to an investor, securities may increase or decrease in value before the investor is able to convert them into cash. Any transaction costs or other expenses involved in liquidating securities received in an in-kind redemption will be borne by the redeeming investor. The fund has committed, in connection with an election under Rule 18f-1 under the Investment Company Act of 1940, to pay all redemptions of fund shares by a single shareholder during any 90-day period in cash, up to the lesser of (i) $250,000 or (ii) 1% of the fund’s net assets measured as of the beginning of such 90-day period. For information regarding procedures for in-kind redemptions, please contact Putnam Retail Management. You will not receive interest on uncashed redemption checks.

• Redemption by the fund. If you own fewer shares than the minimum set by the Trustees (presently 20 shares), the fund may redeem your shares without your permission and send you the proceeds after providing you with at least 60 days’ notice to attain the minimum. To the extent permitted by applicable law, the fund may also redeem shares if you own more than a maximum amount set by the Trustees. There is presently no maximum, but the Trustees could set a maximum that would apply to both present and future shareholders.

• Abandoned property. If your account is held directly with Putnam Investor Services and is later deemed “abandoned” or “unclaimed” under state law, the fund may be required to “escheat” (transfer) the shares in your account, or to redeem those shares and remit the proceeds, to the applicable state’s unclaimed property division. The state may redeem escheated shares. If you subsequently seek to reclaim from the state the proceeds of any sale of your shares, you may only be able to recover the amount received when the shares were sold (and not the amount those shares

are worth currently). It is your responsibility to maintain a correct address for your account, to keep your account active by contacting Putnam Investor Services by mail, by telephone or through Putnam Investor Services’ website, www.putnam.com, and to cash promptly all checks for dividends, capital gains and redemptions. The fund and Putnam Investor Services, Putnam Management, and their respective affiliates will not be liable to fund shareholders or their representatives for good faith efforts to comply with state escheatment laws.

Policy on excessive short-term trading

• Risks of excessive short-term trading. Excessive short-term trading activity may reduce the fund’s performance and harm all fund shareholders by interfering with portfolio management, increasing the fund’s expenses and diluting the fund’s NAV. Depending on the size and frequency of short-term trades in the fund’s shares, the fund may experience increased cash volatility, which could require the fund to maintain undesirably large cash positions or buy or sell portfolio securities it would not have bought or sold otherwise. The need to execute additional portfolio transactions due to these cash flows may also increase the fund’s brokerage and administrative costs and, for investors in taxable accounts, may increase taxable distributions received from the fund.

When the fund invests in foreign securities, its performance may be adversely impacted and the interests of longer-term shareholders may be diluted as a result of time-zone arbitrage, a short-term trading practice that seeks to exploit changes in the value of the fund’s investments that result from events occurring after the close of the foreign markets on which the investments trade, but prior to the later close of trading on the NYSE, the time as of which the fund determines its NAV. If an arbitrageur is successful, he or she may dilute the interests of other shareholders by trading shares at prices that do not fully reflect their fair value.

Because the fund invests in securities that may trade infrequently or may be more difficult to value, such as securities of smaller companies, it may be susceptible to trading by short-term traders who seek to exploit perceived price inefficiencies in the fund’s investments. In addition, the market for securities of smaller companies may at times show “market momentum,” in which positive or negative performance may continue from one day to the next for reasons unrelated to the fundamentals of the issuer. Short-term traders may seek to capture this momentum by trading frequently in the fund’s shares, which will reduce the fund’s performance and may dilute the interests of other shareholders. Because securities of smaller companies may be less liquid than securities of larger companies, the fund may also be unable to buy or sell these securities at desirable prices when the need arises (for example, in response to volatile cash flows caused by short-term trading). Similar risks may apply if the fund holds other types of less liquid securities, including below-investment-grade bonds.

• Fund policies. In order to protect the interests of long-term shareholders of the fund, Putnam Management and the fund’s Trustees have adopted policies and procedures intended to discourage excessive short-term trading. The fund seeks to discourage excessive short-term trading by using fair value pricing procedures to value

investments under some circumstances. In addition, Putnam Management monitors activity in those shareholder accounts about which it possesses, or otherwise obtains, the necessary information in order to detect excessive short-term trading patterns and takes steps to deter excessive short-term traders.

• Account monitoring. Putnam Management’s Compliance Department currently uses multiple reporting tools to detect short-term trading activity occurring in accounts for investors held directly with the Putnam funds as well as in accounts held through financial intermediaries. Putnam Management measures excessive short-term trading in the fund by the number of “round trip” transactions within a specified period of time. A “round trip” transaction is defined as a purchase or exchange into a fund followed, or preceded, by a redemption or exchange out of the same fund. If Putnam Management’s Compliance Department determines that an investor has engaged in excessive short-term trading, Putnam Management will issue the investor and/or the investor’s financial intermediary, if any, a written warning. Putnam Management’s practices for measuring excessive short-term trading activity and issuing warnings may change from time to time. Some types of transactions are exempt from monitoring, including, but not limited to, those in connection with systematic investment or withdrawal plans and reinvestment of dividend and capital gain distributions.

• Account restrictions. In addition to these monitoring practices, Putnam Management and the fund reserve the right to reject or restrict purchases or exchanges for any reason. Continued excessive short-term trading activity by an investor or financial intermediary following a warning may lead to termination of the exchange privilege for that investor or the financial intermediary initiating the trades on the investor’s behalf. Putnam Management may determine that an investor’s trading activity is excessive or otherwise potentially harmful based on various factors, including an investor’s or financial intermediary’s trading history in the fund or other Putnam funds, and may aggregate activity in multiple accounts in the fund or other Putnam funds that Putnam Management believes are under common ownership or control for purposes of determining whether the activity is excessive. If Putnam Management identifies an investor or financial intermediary engaging in excessive trading, it may revoke certain privileges, such as the telephone exchange privilege or the ability to initiate online exchanges via Putnam’s Individual Investor website. Putnam Management may also temporarily or permanently bar the investor or financial intermediary from investing in the fund or other Putnam funds. Putnam Management may take these steps in its discretion even if the investor’s activity does not fall within Putnam Management’s current monitoring parameters for the fund.

• Limitations on the fund’s policies. There is no guarantee that these policies will be able to detect excessive short-term trading in all accounts. For example, Putnam Management currently does not have access to sufficient information to identify each investor’s trading history, and in certain circumstances there may be operational or technological constraints on its ability to enforce the fund’s policies. In addition, even when Putnam Management has sufficient information, its detection methods may not capture all excessive short-term trading.

In particular, many purchase, redemption and exchange orders are received from financial intermediaries that hold omnibus accounts with the fund. Omnibus accounts are accounts in which shares are held in the name of a financial intermediary, such as a retirement plan sponsor, broker, adviser, or third-party administrator or recordkeeper, on behalf of its clients or participants, who are the beneficial owners of the fund shares held in the omnibus account. Putnam Management monitors cash flows into and out of the fund on an ongoing basis. If cash flows or other information indicate that excessive short-term trading may be taking place within an omnibus account, Putnam Management will contact the financial intermediary that maintains the omnibus account to obtain information about trading activity of the beneficial owners and attempt to identify and remedy any excessive trading. However, Putnam Management’s ability to monitor and deter excessive short-term traders in omnibus accounts ultimately depends on the capabilities and cooperation of the financial intermediaries that maintain the omnibus accounts. Financial intermediaries may impose different or additional limits on short-term trading.

Distribution plans and payments to dealers

Putnam funds are distributed primarily through dealers (including any broker, dealer, bank, bank trust department, registered investment advisor, financial planner, retirement plan administrator, and any other institution having a selling, services, or any similar agreement with Putnam Retail Management or one of its affiliates). In order to pay for the marketing of fund shares and services provided to shareholders, the fund has adopted distribution and service (12b-1) plans, which increase the annual operating expenses you pay each year in certain share classes, as shown in the table of annual fund operating expenses in the section Fund summary — Fees and expenses. Putnam Retail Management and its affiliates also make additional payments to dealers that do not increase your fund expenses, as described below.

• Distribution and service (12b-1) plans. The fund’s 12b-1 plans provide for payments at annual rates (based on average net assets) of up to 0.35% on class A shares and 1.00% on class B, class C and class R shares. The Trustees currently limit payments on class A and class R shares to 0.25% and 0.50% of average net assets, respectively. Because these fees are paid out of the fund’s assets on an ongoing basis, they will increase the cost of your investment. The higher fees for class B, class C and class R shares may cost you more over time than paying the initial sales charge for class A shares. Because class R shares, unlike class B and class C shares, do not convert to class A shares, class R shares may cost you more over time than class B and class C shares. Class R6 and class Y shares, for shareholders who are eligible to purchase them, will be less expensive than other classes of shares because they do not bear sales charges or 12b-1 fees.

• Payments to dealers. If you purchase your shares through a dealer, your dealer generally receives payments from Putnam Retail Management representing some or all of the sales charges and distribution and service (12b-1) fees, if any, shown in the tables under Fund summary — Fees and expenses at the front of this prospectus.

Putnam Retail Management and its affiliates also pay additional compensation to selected dealers in recognition of their marketing support and/or program servicing (each of which is described in more detail below). These payments may create an incentive for a dealer firm or its representatives to recommend or offer shares of the fund or other Putnam funds to its customers. These additional payments are made by Putnam Retail Management and its affiliates and do not increase the amount paid by you or the fund as shown under Fund summary — Fees and expenses.

The additional payments to dealers by Putnam Retail Management and its affiliates are generally based on one or more of the following factors: average net assets of a fund attributable to that dealer, sales or net sales of a fund attributable to that dealer, or reimbursement of ticket charges (fees that a dealer firm charges its representatives for effecting transactions in fund shares), or on the basis of a negotiated lump sum payment for services provided.

Marketing support payments are generally available to most dealers engaging in significant sales of Putnam fund shares. These payments are individually negotiated with each dealer firm, taking into account the marketing support services provided by the dealer, including business planning assistance, educating dealer personnel about the Putnam funds and shareholder financial planning needs, placement on the dealer’s preferred or recommended fund company list, access to sales meetings, sales representatives and management representatives of the dealer, market data, as well as the size of the dealer’s relationship with Putnam Retail Management. Although the total amount of marketing support payments made to dealers in any year may vary, on average, the aggregate payments are not expected, on an annual basis, to exceed 0.085% of the average net assets of Putnam’s retail mutual funds attributable to the dealers.

Program servicing payments, which are paid in some instances to dealers in connection with investments in the fund through dealer platforms and other investment programs, are not expected, with certain limited exceptions, to exceed 0.20% of the total assets in the program on an annual basis. These payments are made for program or platform services provided by the dealer, including shareholder recordkeeping, reporting, or transaction processing, as well as services rendered in connection with dealer platform development and maintenance, fund/investment selection and monitoring, or other similar services.

You can find a list of all dealers to which Putnam made marketing support and/or program servicing payments in 2022 in the SAI, which is on file with the SEC and is also available on Putnam’s website at putnam.com. You can also find other details in the SAI about the payments made by Putnam Retail Management and its affiliates and the services provided by your dealer. Your dealer may charge you fees or commissions in addition to those disclosed in this prospectus. You can also ask your dealer about any payments it receives from Putnam Retail Management and its affiliates and any services your dealer provides, as well as about fees and/or commissions it charges.

• Other payments. Putnam Retail Management and its affiliates may make other payments (including payments in connection with educational seminars or conferences) or allow other promotional incentives to dealers to the extent permitted by SEC and NASD (as adopted by FINRA) rules and by other applicable laws and regulations. The fund’s transfer agent may also make payments to certain financial intermediaries in recognition of subaccounting or other services they provide to shareholders or plan participants who invest in the fund or other Putnam funds through their retirement plan. See the discussion in the SAI under Management — Investor Servicing Agent for more details.

Fund distributions and taxes

The fund normally distributes any net investment income and any net realized capital gains annually. You may choose to reinvest distributions from net investment income, capital gains or both in additional shares of your fund or other Putnam funds, or you may receive them in cash in the form of a check or an electronic deposit to your bank account. If you do not select an option when you open your account, all distributions will be reinvested. If you choose to receive distributions in cash, but correspondence from the fund or Putnam Investor Services is returned as “undeliverable,” the distribution option on your account may be converted to reinvest future distributions in the fund. You will not receive interest on uncashed distribution checks.

For shares purchased through your employer’s retirement plan, the terms of the plan will govern how the plan may receive distributions from the fund.

For federal income tax purposes, distributions of net investment income are generally taxable to you as ordinary income. Taxes on distributions of capital gains are determined by how long the fund owned (or is deemed to have owned) the investments that generated them, rather than by how long you have owned (or are deemed to have owned) your shares. Distributions that the fund properly reports to you as gains from investments that the fund owned for more than one year are generally taxable to you as long-term capital gains includible in net capital gain and taxed to individuals at reduced rates. Distributions of gains from investments that the fund owned for one year or less are generally taxable to you as ordinary income. Distributions that the fund properly reports to you as “qualified dividend income” are taxable at the reduced rates applicable to your net capital gain provided that both you and the fund meet certain holding period and other requirements. Distributions are taxable in the manner described in this paragraph whether you receive them in cash or reinvest them in additional shares of this fund or other Putnam funds.

Distributions by the fund to retirement plans that qualify for tax-advantaged treatment under federal income tax laws will not be taxable. Special tax rules apply to investments through such plans. You should consult your tax advisor to determine the suitability of the fund as an investment through such a plan and the tax treatment of distributions (including distributions of amounts attributable to an investment in the fund) from such a plan.

Unless you are investing through a tax-advantaged retirement account (such as an IRA), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution because doing so may cost you money in taxes. Distributions are taxable to you even if they are paid from income or gains earned by the fund before your investment (and thus were included in the price you paid). Contact your financial representative or Putnam to find out the distribution schedule for your fund.

The fund’s investments in foreign securities may be subject to foreign withholding or other taxes. In that case, the fund’s return on those investments would be decreased. Shareholders generally will not be entitled to claim a credit or deduction with respect to these foreign taxes. In addition, the fund’s investments in foreign securities or foreign currencies may increase or accelerate the fund’s recognition of ordinary income and may affect the timing or amount of the fund’s distributions.

The fund’s use of derivatives, if any, may affect the amount, timing and character of distributions to shareholders and, therefore, may increase the amount of taxes payable by shareholders.

Any gain resulting from the sale or exchange of your shares generally also will be subject to tax.

The above is a general summary of the tax implications of investing in the fund. Please refer to the SAI for further details. You should consult your tax advisor for more information on your own tax situation, including possible foreign, state and local taxes.

Information about the Summary Prospectus, Prospectus, and SAI

The summary prospectus, prospectus, and SAI for a fund provide information concerning the fund. The summary prospectus, prospectus, and SAI are updated at least annually and any information provided in a summary prospectus, prospectus, or SAI can be changed without a shareholder vote unless specifically stated otherwise.

EDWARD D. JONES & CO., L.P. (“EDWARD JONES”)

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

Effective on or after January 1st, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the Putnam funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

Rights of Accumulation (“ROA”)

• The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the Putnam funds held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

• The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

• ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent (“LOI”)

• Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

• If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

• Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones uassociatender its policies and procedures) as the associate. This waiver will continue for the remainder of the ’s life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones’ policies and procedures.

• Shares purchased in an Edward Jones fee-based program.

• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

• Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front-end sales load and one of the following:

• Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

• Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

Contingent Deferred Sales Charge (“CDSC”) Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

• The death or disability of the shareholder.

• Systematic withdrawals with up to 10% per year of the account value.

• Return of excess contributions from an Individual Retirement Account (IRA).

• Shares redeemed as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.
