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 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, PanAgora pursues the fund’s goal by following an investment strategy designed to generate returns from investing in a combination of asset classes with diversified risk characteristics.

A description of the fund’s risk parity strategy, as well as the types of investments that the fund may make and the associated risks, follows.

Prospectus   9

In allocating the fund’s assets among the different asset classes, PanAgora employs a proprietary “risk parity” approach, which seeks to balance the fund’s portfolio risks across and within asset classes. This risk parity approach relies on quantitative models and information and data inputs to those models.

When allocating investments across asset classes, the fund generally allocates a greater portion of its assets to asset classes PanAgora views as having lower risk, such as developed market bonds, than to asset classes PanAgora views as having higher risk, such as global equities.

In its “neutral” position, the fund’s assets are generally strategically allocated among the different asset classes so that the anticipated contribution of each asset class to the overall risk of the fund will be approximately as follows: 40% from equity risk; 40% from fixed income risk; and 20% from inflation risk. However, there is no assurance that the anticipated contribution of each asset class to the fund’s overall risk can be achieved; in addition, PanAgora may seek different risk contributions from time to time. Because of the difference in the amount of risk inherent in these asset classes, the percentage of the fund’s assets allocated to a particular asset class is likely to be significantly different from the anticipated contribution to overall risk from that asset class. PanAgora also expects to vary the fund’s allocation to the asset classes tactically in response to changing market conditions, including in an effort to protect from downside risk, using a proprietary dynamic risk allocation approach that will cause the fund to deviate from its neutral position. Additionally, market movements are likely to change the risk levels and risk allocations of the fund.

When allocating investments within each asset class, PanAgora’s risk parity approach seeks to diversify risk exposures across a variety of factors. For example, while a market index-like, capitalization-based index, may reflect very different exposures to particular industry sectors, geographies, companies and commodity types, PanAgora seeks to invest the fund’s assets so that the fund’s exposures to the risks associated with these and other factors more balanced.

PanAgora believes that a risk parity approach may result in a portfolio that exhibits a certain level of volatility. Volatility is a statistic measurement of the variation of return. However, there can be no assurance that the fund will exhibit the desired level of volatility. The fund’s ability to achieve its investment objective depends upon PanAgora’s analysis of various factors, including economic and market factors, and the mix of asset classes that results from such analysis. PanAgora’s analysis, including any evaluations and assumptions regarding such factors, may prove incorrect. The fund may experience losses or poor relative performance if PanAgora allocates a significant portion of the fund’s assets to an asset class or subset of an asset class that does not perform well relative to other asset classes or other subsets of asset

10   Prospectus

classes. The fund may underperform funds that allocate their assets differently than the fund, due to differences in the relative performance of asset classes and subsets of asset classes.

The fund will gain exposure to different areas of risk either through direct investment or through derivative instruments, primarily including forwards, futures, and swaps, but which may also include, but are not limited to, options. The fund may invest without limit in equity securities, including, but not limited to, global developed markets, large-cap equities, emerging markets equities, and U.S. small and mid-cap equities. The fund may additionally invest in fixed-income securities of any credit quality, duration or maturity (including, but not limited to, U.S and non-U.S. sovereign bonds, global inflation-linked government bonds (including Treasury Inflation Protected Securities, and investment-grade corporate bonds), commodities (including through, but not limited to, commodity-linked notes and commodity-related derivative instruments (primarily commodity futures and swaps on commodity futures)), exchange-traded funds (“ETFs”), exchange-traded notes, and emerging markets and other currencies (including through cash bonds and currency forwards). These asset classes offer different return potential and exposure to different investment risks.

A significant portion of the assets of the fund will be invested in short-term instruments, which may include, but are not limited to, U.S. Government securities (including U.S. Treasury bills), U.S. Government agency securities, investment-grade corporate obligations, Eurodollar obligations, bankers’ acceptances, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market fund shares, and cash and cash equivalents generally with one year or less term to maturity. These investments serve as collateral for the derivative positions the fund takes and also may earn income for the fund.

Prospectus   11

If the quantitative models or data used in managing the fund prove to be incorrect or incomplete, investment decisions made in reliance on the models or data may not produce the desired results and may cause the fund to underperform its benchmark or other funds with a similar investment goal, and the fund may realize losses. For example, PanAgora may, in reliance on faulty models or data, be unsuccessful in its efforts to manage the fund’s overall level of volatility and its efforts to diversify risk. Any hedging based on faulty models and data may prove to be unsuccessful. In addition, models may incorrectly forecast future behavior, leading to potential losses on a cash flow and/or mark-to-market basis. Use of these models in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind) also may result in losses for the fund.

All models require data. Some of the models that PanAgora may use are typically constructed based on historical data, and the success of these models is dependent largely on the accuracy and reliability of the supplied historical data. If incorrect data is entered into a model, the resulting output will be incorrect. As a result, any investment decisions made in reliance on the incorrect output from a model may not produce the desired results and the fund may realize losses. Even when data is correctly inputted into a model, the resulting information may differ, sometimes substantially, from other available data. For example, “model prices” that are provided by a model will often differ substantially from market prices, particularly for instruments that are complex in nature, such as derivatives.

Models also rely on the proper functioning of hardware and technology, which are subject to disruption risk. There is no guarantee that the hardware and technology on which the models rely will be uninterrupted or error free, or that any defects in such hardware or technology will be able to be corrected in a short time period.

12   Prospectus

Derivatives (including forwards, futures, and swaps) involve special risks and may result in losses. The value of derivatives may move in unexpected ways due to unanticipated market movements, the use of leverage, imperfect correlation between the derivatives instrument and the reference asset, or other factors, especially in unusual market conditions, and may result in increased volatility. Derivatives may be difficult to value and may increase the fund’s transactions costs. The successful use of derivatives depends on the ability to manage these sophisticated instruments. There is no assurance that the fund’s use of derivative instruments will enable the fund to achieve its investment objective or that PanAgora will be able to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors.

Other risks arise from the potential inability to terminate or sell derivatives positions. A liquid secondary market may not always exist for the fund’s derivatives positions. In fact, many over-the-counter instruments (investments not traded on an exchange) will not be liquid. Derivatives, particularly over-the-counter instruments, also involve the risk that the other party to the derivatives transaction will not meet its obligations. Derivatives also are subject to the risk that the fund may be delayed or prevented from recovering margin or other amounts deposited with a clearinghouse, futures commission merchant or other counterparty. If the fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements at a time when it may be disadvantageous to do so.

Derivatives transactions (including forwards, futures, and swaps) often involve “leverage,” 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. Derivatives and other transactions that give rise to leverage may cause the fund’s performance to be more volatile than if the fund had not been leveraged, as leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the fund’s exposure to an asset class. Leveraging also may require that the fund liquidate portfolio securities when it may not be advantageous to do so, to satisfy its obligations or to meet segregation requirements. Leveraging may expose the fund to losses in excess of the amounts invested. Furthermore, if the fund uses leverage through purchasing derivative instruments, the fund has the risk that losses may exceed the net assets of the Fund. The risk of loss from short derivatives positions is theoretically unlimited.

A portion of any capital gains from futures contracts in which the fund invests directly will be treated for federal income tax purposes as short-term capital gains that, when distributed to taxable shareholders, will be taxable as ordinary income. The fund’s investments in swaps will generate ordinary income and losses for federal income tax purposes. The fund’s investments in futures and swaps may cause the fund to recognize income without receiving cash with which to make the distributions necessary to qualify and be eligible for treatment as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) and avoid

Prospectus   13

a fund-level tax. The fund may therefore need to liquidate other investments, including when it is not advantageous to do so, to meet its distribution requirement. The fund is not permitted to carry forward any net ordinary losses it realizes in a taxable year to offset ordinary income it realizes in subsequent taxable years.

For further information about additional types and risks of derivatives and the fund’s asset segregation policies, see Miscellaneous Investments, Investment Practices and Risks in the Statement of Additional Information (SAI).

14   Prospectus

Some investments give the issuer the option to call or redeem an investment before its maturity date. If an issuer calls or redeems an investment during a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering a lower yield, and therefore the fund might not benefit from any increase in value as a result of declining interest rates.

The fund may invest in inflation-protected securities issued by the U.S. Department of Treasury, by non-U.S. governments, or by private issuers. Inflation-protected securities are debt instruments whose principal and/or interest are adjusted for inflation. If inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in the value of inflation-protected securities. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in the value of inflation-protected securities. When real interest rates are rising faster than nominal interest rates, inflation-indexed bonds, including Treasury Inflation Protected Securities, may experience greater losses than other fixed income securities with similar durations. Inflation-protected securities issued by the U.S. Treasury pay a fixed rate of interest that is applied to an inflation-adjusted principal amount. The principal amount is adjusted based on changes in the Consumer Price Index, a measure of inflation. The principal due at maturity is typically equal to the inflation-adjusted principal amount, or to the instrument’s original par value, whichever is greater. Because the principal amount would be adjusted downward during a period of deflation, the fund will be subject to deflation risk with respect to its investments in these securities. In addition, if the fund purchases inflation-adjusted debt instruments in the secondary market whose principal values have been adjusted upward due to inflation since issuance, the fund may experience a loss if there is a subsequent period of deflation.

Prospectus   15

Specifically, in the commodity futures markets, producers of the underlying commodity may decide to hedge the price risk of selling the commodity by selling futures contracts on one day to lock in the price of the commodity at delivery on the next day. In order to induce speculators to purchase the other side of the same futures contract, the commodity producer generally must sell the futures contract at a lower price than the expected future spot price of the commodity. Conversely, if most hedgers in the futures market are purchasing futures contracts to hedge against a rise in prices, then speculators will only sell the other side of the futures contract at a higher futures price than the expected future spot price of the commodity. The changing nature of the hedgers and speculators in the commodities markets will influence whether the prices of commodity-linked derivatives are above or below the expected future spot price, which can have significant implications for the fund and the subsidiary.

Commodities markets (and commodity-linked derivative instruments) may be subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators and government regulation and intervention.

Each of Putnam Investment Management, LLC (“Putnam Management”) and PanAgora is registered as a commodity pool operator (“CPO”) with the Commodity Futures Trading Commission (“CFTC”) and is considered a CPO with respect to the fund. Each of Putnam Investment Management, PanAgora and the fund therefore are subject to regulation by the CFTC under the Commodity Exchange Act. Consequently, Putnam Management, PanAgora and the fund are required to comply with applicable CFTC regulations. Compliance with these regulations may increase the fund’s operating expenses.

The fund’s investments in U.S. government securities and U.S. government agency securities may also be subject to credit risk. Although securities issued or guaranteed by the U.S. Government are generally considered to be subject to a relatively low amount of credit risk, most securities issued by agencies and instrumentalities of the U.S. Government are not backed by the full faith and credit of the U.S. Government and are supported only by the credit of the issuing agency or instrumentality. If the fund invests in debt securities, the value of your investment may be adversely affected if a security’s credit rating is downgraded, an issuer of an investment held by the fund fails to pay an obligation on a timely basis, otherwise defaults, or is perceived by other investors to be less creditworthy.

The fund may also be subject to the credit risk presented by another party (counterparty credit risk) to the extent it engages in transactions, such as securities loans, repurchase agreements or certain derivatives, which involve a promise by the counterparty to honor an obligation to the fund. If the fund engages in transactions with a counterparty, the value of your investment may be adversely affected if the counterparty files for bankruptcy, becomes insolvent, or otherwise becomes unable or unwilling to honor its obligation to the fund.

The value of a debt instrument may also be affected by changes in, or perceptions of, the financial condition of the issuer, borrower, counterparty, or other entity, or underlying collateral or assets, or changes in, or perceptions of, specific or general market, economic, industry, political, regulatory, geopolitical, environmental, public health, and other conditions.

Although investment-grade investments generally have lower credit risk, they may share some of the risks of lower-rated investments.

An investment company or ETF may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the fund’s performance. Shares of a closed-end investment company or ETF may trade at a premium or discount to the NAV of its portfolio securities depending on a variety of factors, including market supply and demand.

18   Prospectus

The risks of foreign investments are typically increased in countries with less developed markets, which are sometimes referred to as emerging markets. Emerging markets may have less developed economies and legal and regulatory systems, and may be susceptible to greater political and economic instability than developed foreign markets. Countries with emerging markets are also more likely to experience high levels of inflation or currency devaluation, and investments in emerging markets may be more volatile and less liquid than investments in developed markets. For these and other reasons, investments in emerging markets are often considered speculative.

Certain risks related to foreign investments 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.

Prospectus   19

The subsidiary is managed on an aggregate basis with the fund pursuant to compliance policies and procedures that are the same, in all material respects, as the policies and procedures adopted by the fund. As a result, PanAgora, in managing the subsidiary’s portfolio, is subject to the same investment policies and restrictions that apply to the management of the fund, and, in particular, to the requirements (which are consistent with the requirements of the 1940 Act) relating to portfolio leverage, liquidity, brokerage, transactions with affiliated persons, and the timing and method of the valuation of the subsidiary’s portfolio investments and shares of the subsidiary. These policies and restrictions are described in detail in the SAI. The fund’s Chief Compliance Officer oversees implementation of the subsidiary’s policies and procedures, and makes periodic reports to the Board regarding the subsidiary’s compliance with its policies and procedures. The fund and subsidiary test for compliance with certain investment restrictions on a consolidated basis.

PanAgora provides investment management and other services to the subsidiary. PanAgora does not receive separate compensation from the subsidiary for providing it with investment management or administrative services. However, Putnam Management pays PanAgora based on the fund’s assets, including the assets invested in the subsidiary. The subsidiary will also enter into separate contracts for the provision of custody (which are consistent with the requirements of the 1940 Act) and audit services with the same or with affiliates of the same service providers that provide those services to the fund.

By investing in the subsidiary, the fund is indirectly exposed to the risks associated with the subsidiary’s investments. The commodity-related instruments held by the subsidiary are generally similar to those that are permitted to be held by the fund and are subject to the same risks that apply to similar investments if held directly by the fund (see “Derivatives” above).

There can be no assurance that the investment objective of the subsidiary will be achieved. The subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all of the investor protections of the 1940 Act. However, the fund wholly owns and controls the subsidiary, and the fund and the subsidiary are both managed by Putnam Investment Management, making it unlikely that the subsidiary will take action contrary to the interests of the fund and its shareholders. The Board has oversight responsibility for the investment activities of the fund, including its investment in the subsidiary, and the fund’s role as sole

20   Prospectus

shareholder of the subsidiary. To the extent applicable to the investment activities of the subsidiary, the subsidiary will be subject to the same investment restrictions and limitations, and will follow the same compliance policies and procedures, as the fund. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the fund and/or the subsidiary to operate as described in this prospectus and the SAI and could adversely affect the fund.

The financial statements of the subsidiary will be consolidated with the fund’s financial statements in the fund’s Annual and Semi-Annual Reports. The fund’s Annual and Semi-Annual Reports are distributed to shareholders, and copies of the reports are provided without charge upon request as indicated on the back cover of this prospectus. Please refer to the SAI for additional information about the organization and management of the subsidiary.

The fund’s investment in the subsidiary is expected to provide the fund with exposure to the commodities markets within the limitations of the federal tax requirements of Subchapter M of the Code. The fund’s pursuit of its investment strategy may be limited by the fund’s intention to qualify for treatment as a regulated investment company under Subchapter M of the Code. As noted below in “Fund distributions and taxes,” the rules regarding the extent to which annual net income, if any, realized by the subsidiary and included in the fund’s annual income for U.S. federal income purposes will constitute “qualifying income” for purposes of the fund’s qualification as a regulated investment company under the Code are unclear and currently under consideration.

Prospectus   21

The fund generally will use its short-term instruments or other liquid assets to cover its obligations. The fund will take action as necessary for the purpose of complying with the asset segregation policy stated above. Such actions may include the sale of the fund’s portfolio investments. There is a possibility that segregation of a large percentage of a fund’s assets could impede portfolio management or the fund’s ability to meet redemption requests or other current obligations.

The novel coronavirus (COVID-19) pandemic and efforts to contain its spread have negatively affected, and are likely to continue to negatively affect, the global economy, the economies of the United States and other individual countries, and the financial performance of individual issuers, sectors, industries, asset classes, and markets in significant and unforeseen ways. The COVID-19 pandemic has resulted in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, and economic downturns and recessions, and these effects may continue for an extended period of time and may increase in severity over time. In addition, actions taken by government and quasi-governmental authorities and regulators throughout the world in response to the COVID-19 pandemic, including significant fiscal and monetary policy changes, may affect the value, volatility, and liquidity of some securities and other assets. Given the significant uncertainty surrounding the magnitude, duration, reach, costs and effects of the COVID-19 pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, it is difficult to predict its potential impacts on the fund’s investments. 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.

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-advisory agreement described below is discussed in the fund’s annual report to shareholders dated August 31, 2020.

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 all open-end funds sponsored by Putnam Management for which PanAgora is acting as sub-adviser launched on or after the date of the fund’s management contract, as determined at the close of each business day during the month.

The fund paid Putnam Management a management fee (after any applicable waivers) of 0.51% of average net assets for the fund’s last fiscal year.

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

The subsidiary pays a monthly management fee to Putnam Management at the same rate as the fund. For so long as the fund invests in the subsidiary, the management fee paid by the fund to Putnam Management is reduced by an amount equal to the management fee Putnam Management receives from the subsidiary under the management contract between Putnam Management and the subsidiary.

Putnam Management has retained its affiliate PanAgora to make investment decisions for such fund assets as may be designated from time to time for its management by Putnam Management. Putnam Management (and not the fund) pays a quarterly sub-advisory fee to PanAgora for its services. For the fund’s last fiscal year, Putnam Management paid PanAgora an effective management fee of 0.35% of the average net asset value (NAV) of fund assets managed by PanAgora.

PanAgora is located at One International Place, 24th Floor, Boston, Massachusetts 02210.

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 at its fair value when the relevant 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. Although the threshold may be revised from time to time and the number of days on which fair value prices will be used will depend upon 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:

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 a 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:

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”:

32   Prospectus

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.

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

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 Mutual Funds, then Pricing and performance, and then About fund costs, and in the SAI.

Prospectus   33

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.

34   Prospectus

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

Prospectus   35

Putnam fund that does charge a deferred sales charge, and will not be affected by any subsequent exchanges among funds.

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.

36   Prospectus

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 $500,000 or more (other than by an employer-sponsored retirement plan) will be subject to a 1.00% deferred sales charge if redeemed within nine 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.

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

Prospectus   37

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.

Policy on excessive short-term trading

Because 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.

When 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

38   Prospectus

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.

Prospectus   39

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.

40   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.

Prospectus   41

You can find a list of all dealers to which Putnam made marketing support and/or program servicing payments in 2020 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.

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 and gains on the sale of or payment on bonds characterized as market discount 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

42   Prospectus

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 certain debt obligations may cause the fund to recognize taxable income in excess of the cash generated by such obligations. Thus, the fund could be required at times to liquidate other investments, including when it is not advantageous to do so, in order to satisfy its distribution requirements.

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 may affect the amount, timing and character of distributions to shareholders and, therefore, may increase the amount of taxes payable by shareholders. A portion of any capital gains from futures contracts in which the fund invests directly will be treated for federal income tax purposes as short-term capital gains that, when distributed to taxable shareholders, will be taxable as ordinary income. The fund’s investments in swaps will generate ordinary income and losses for federal income tax purposes. The fund’s investments in futures and swaps may cause the fund to recognize income without receiving cash with which to make the distributions necessary to qualify and be eligible for treatment as a regulated investment company under Subchapter M of the Code and avoid a fund-level tax. The fund may therefore need to liquidate other investments, including when it is not advantageous to do so, to meet its distribution requirement. The fund is not permitted to carry forward any net ordinary losses it realizes in a taxable year to offset ordinary income it realizes in subsequent taxable years.

The fund intends to gain exposure to commodities and commodity-related investments, in whole or in part, through the fund’s investment in the subsidiary. It is expected that all of the subsidiary’s income will be “subpart F income” currently

Prospectus   43

included in the fund’s income as ordinary income for federal income tax purposes. The rules regarding the extent to which such subpart F inclusions will be treated as “qualifying income” for purposes of the 90% gross income requirement for qualification as a regulated investment company under Subchapter M of the Code are unclear and currently under consideration. In the absence of further guidance, the fund will seek to ensure that it satisfies the 90% gross income requirement, including but not limited to by ensuring that the subsidiary timely distributes to the fund an amount equal to the subsidiary’s subpart F income by the end of the subsidiary’s taxable year. In order to make such distributions, the subsidiary may be required to sell investments, including at a time when it may be disadvantageous to do so. Net losses incurred by the subsidiary during a tax year do not flow through to the fund and thus will not be available to offset income or capital gain generated from the fund’s other investments. In addition, the subsidiary is not permitted to carry forward any net ordinary losses it realizes in a taxable year to offset ordinary income it realizes in subsequent taxable years. You should consult the SAI for additional information.

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.
