The fund's [prospectus and statement of additional information](http://www.sec.gov/Archives/edgar/data/../../../ix?doc=/Archives/edgar/data/81248/000119312526023829/d22151d485bpos.htm), both dated February 1, 2026, as may be supplemented, are all incorporated by reference into this Summary Prospectus.

**Goal** 

The fund seeks as high a rate of current income as the Investment Manager (as defined below) believes is consistent with preservation of capital and maintenance of liquidity.

**Fees and expenses** 

The following tables describe the fees and expenses you may pay if you buy, hold and sell shares of the fund. **You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.** Information about sales charge discounts is available from your financial professional and in the Appendix to the fund's prospectus.

| **Share class** | **Maximum sales charge (load)<br>imposed on purchases (as a<br>percentage of offering price)** | **Maximum deferred sales charge<br>(load) (as a percentage of original<br>purchase price or redemption<br>proceeds, whichever is lower)** |
| Class A |  | 1.00%<sup>1</sup> |
| Class C |  | 1.00%<sup>1</sup> |
| Class R |  |  |

---

<sup>1</sup> A deferred sales charge on class A and C shares may apply to certain redemptions of shares purchased by exchange from another Putnam fund. The rate of the deferred sales charge for class C shares will be determined based on the time between the original purchase of class C shares from the other Putnam fund(s) and date of redemption of shares from this fund. 

**Annual Fund Operating Expenses**

|  Class C | 0.26% |  | 0.16% | 0.42% |
|  Class R | 0.26% |  | 0.16% | 0.42% |

<sup>1</sup> The fund's Board of Trustees has determined to limit payments under the distribution and services (12b-1) plans in place with respect to class C and class R shares to 0.00% of average net assets. 

**Example** 

The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem or hold all your shares at the end of those periods. It assumes a 5% return on your investment each year and that the fund's operating expenses remain the same (except that any applicable fee waiver or expense reimbursement is reflected only through its expiration date). Your actual costs may be higher or lower.

**Investments, risks, and performance** 

**Investments** 

The fund invests mainly in money market instruments that are high quality and have short-term maturities. The fund invests significantly in certificates of deposit, commercial paper (including asset-backed commercial paper), U.S. government debt and repurchase agreements, corporate obligations and time deposits. The fund may also invest in U.S. dollar denominated foreign securities of these types. The Investment Manager may consider, among other factors, credit and interest rate risks and characteristics of the issuer or counterparty, as well as general market conditions, when deciding whether to buy or sell investments.

**Risks** 

It is important to understand that you can lose money by investing in the fund.

**Market risk:** The effects of inflation may erode the value of an investment in the fund over time. 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, government actions, geopolitical events or changes, outbreaks of infectious illnesses or other widespread public health issues, and factors related to a specific issuer, asset class, geography, industry or sector. These and other factors may lead to increased volatility and reduced liquidity in the fund's portfolio holdings, may negatively impact the fund's performance, and may exacerbate other risks to which the fund is subject.

**Interest rate risk:** The values of money market investments usually rise and fall in response to changes in interest rates. Interest rate risk is generally lowest for investments with short maturities (a significant part of the fund's investments).

**Credit quality risk:** Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value. Although the fund only buys high quality investments, investments backed by a letter of credit have the risks that the provider of the letter of credit will not be able to fulfill its obligations to the issuer.

------

**Focus of investments risk:** To the extent that the fund invests significantly in a particular industry, it runs an increased risk of loss if economic or other developments affecting that industry cause the prices of related money market investments to fall.

**Foreign investments risk:** The fund may invest in money market instruments of foreign issuers that are denominated in U.S. dollars. Foreign investments involve certain special risks, such as unfavorable political and legal developments, limited financial information, and economic and financial instability. In addition, the liquidity of these investments may be more limited than for most U.S. investments. Foreign settlement procedures may also involve additional risks.

**Management and operational risk:** There is no guarantee that the investment techniques, analyses, or judgments that the Investment Manager applies in making investment decisions for the fund will produce the intended outcome or that the investments selected for the fund will perform as well as other securities that were not selected for the fund. The Investment Manager, or the fund's other service providers, may experience disruptions or operating errors that could negatively impact the fund.

The fund may not achieve its goal, and it is not intended to be a complete investment program. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund may impose a fee upon the sale of your shares. An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's sponsor is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.

**Performance** 

The accompanying bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Class A shares. The table shows the average annual total returns of each class of the fund that has been in operation for at least one full calendar year. Performance for classes other than those shown may vary from the performance shown to the extent the expenses for those classes differ. The fund makes updated performance information, including its current net asset value, available at www.franklintempleton.com.

*The fund's past performance is not necessarily an indication of how the fund will perform in the future.*

**Purchase and sale of fund shares** 

In accordance with the Securities and Exchange Commission's ("SEC") rules governing money market funds, the fund operates as a retail money market fund and requires all beneficial owners to be natural persons.

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.

When opening an account, you must complete and mail a Putnam account application, along with a check made payable to the fund, to: Putnam Investor Services, P.O. Box 219697, Kansas City, MO 64121-9697. The minimum initial

------

investment of $500 is currently waived, although the fund reserves the right to reject initial investments under $500 at its discretion. There is no minimum for subsequent investments. Shares are sold at a net asset value of $1.00 per share, without any initial sales charge.

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") and the Federal Reserve Bank of New York ("FRBNY") are both open. On any day when the NYSE, the FRBNY or the bond markets (as recommended by the Securities Industry and Financial Markets Association ("SIFMA")) close early due to an unanticipated event, or if trading on the NYSE is restricted, an emergency arises, or as otherwise permitted by the SEC, the fund reserves the right to close early and make its net asset value calculation as of the time of its early close. Shares may be sold or exchanged by mail, by phone, or, for exchanges only, online at www.franklintempleton.com. Some restrictions may apply.

------

**Tax information** 

The fund's distributions will be taxed as ordinary income 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.
