Ultra Short MAC Series, the following language is added to the section CHARGES AND EXPENSES, and existing references to the Management Contract in that section are deemed to include the New Management Contract (defined below), as the context requires:

Effective July 15, 2024, Putnam Management transferred all of its rights and obligations under the existing management contract between Putnam Management and your fund to Franklin Advisers by means of an assignment and assumption agreement (the "Transfer"), and Franklin Advisers assumed the role of investment adviser for the fund pursuant to a new management contract (the "New Management Contract"). The terms of the New Management Contract are substantially similar to the terms of the fund's previous management contract, and the fees payable under the New Management Contract are identical to those under the previous management contract. In order to provide continuity in the determination of the management fee rates for all funds whose fee rates are 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) ("Total Open-End Mutual Fund Average Net Assets"), the assignment and assumption agreement includes an acknowledgment by Franklin Advisers and Putnam Management that each fund whose assets are counted in the calculation of Total Open-End Mutual Fund Average Net Assets will continue to be deemed an open-end fund sponsored by Putnam Management.

In connection with the Transfer, as of July 15, 2024, Putnam Management also transferred all of its rights and obligations under the sub-management contract between Putnam Management and Putnam Investments Limited ("PIL") to Franklin Advisers in respect of the fund by means of an assignment and assumption agreement, resulting in a new sub-management contract with respect to the fund. The new sub-management contract replaces, and has terms that are substantially similar to, the previous sub-management contract, as described below in the section "Management-The Sub-Advisers" of this SAI.

Effective July 15, 2024, Putnam Management transferred all of its rights and obligations under the existing management contract between Putnam Management and your fund to Franklin Advisers by means of an assignment and assumption agreement (the "Transfer"), and Franklin Advisers assumed the role of investment adviser for the fund pursuant to a new management contract (the "New Management Contract"). The terms of the New Management Contract are

substantially similar to the terms of the fund's previous management contract, and the fees payable under the New Management Contract are identical to those under the previous management contract.

In connection with the Transfer, as of July 15, 2024, Putnam Management also transferred all of its rights and obligations under the sub-management contract between Putnam Management and Putnam Investments Limited ("PIL") to Franklin Advisers in respect of the fund by means of an assignment and assumption agreement, resulting in a new sub-management contract with respect to the fund. The new sub-management contract replaces, and has terms that are substantially similar to, the previous sub-management contract, as described below in the section "Management-The Sub-Advisers" of this SAI.

· For Putnam Dynamic Asset Allocation Balanced Fund, Putnam Dynamic Asset Allocation Conservative Fund, Putnam Dynamic Asset Allocation Equity Fund, Putnam Dynamic Asset Allocation Growth Fund, Putnam Multi-Asset Income Fund, and Putnam VT Global Asset Allocation Fund, the following language is added to the section CHARGES AND EXPENSES:

Effective July 15, 2024, Putnam Management transferred all of its rights and obligations under the existing sub-advisory contract between Putnam Management, PIL, and The Putnam Advisory Company, LLC ("PAC") in respect of the fund to Franklin Advisers by means of an assignment and assumption agreement, resulting in a new sub-advisory contract with respect to the fund. The new sub-advisory contract replaces, and has terms that are substantially similar to, the previous sub-advisory contract among Putnam Management, PIL, and PAC, as described below in the section "Management-The Sub-Advisers" of this SAI.

· For each fund listed in the table above for which Putnam Management serves as Investment Manager, the following language is added to the section CHARGES AND EXPENSES:

Effective July 15, 2024, Putnam Management retained its affiliate, Franklin Advisers, to make investment decisions for such fund assets as may be designated from time to time for its management by Putnam Management and to provide certain other advisory and related services pursuant to a new subadvisory agreement relating to the fund. Please see "Management-The Sub-Advisers" of this SAI for a further discussion of the new subadvisory agreement.

· For each fund listed in the table above, the sub-section Personal Investments by Employees of Putnam Management and Putnam Retail Management and Officers and Trustees of the Fund in the section MANAGEMENT is replaced with the following:

Employees of Putnam Management, PIL, PAC and Putnam Retail Management and officers and Trustees of the fund are subject to significant restrictions on engaging in personal securities transactions. These restrictions are set forth in the Codes of Ethics adopted by Putnam Management, PIL, PAC and Putnam Retail Management and by the fund (the "Code of Ethics"). The Code of Ethics, in accordance with Rule 17j-1 under the 1940 Act, contains provisions and

6

requirements designed to identify and addresses certain conflicts of interest between personal investment activities and the interests of the fund.

The Code of Ethics does not prohibit personnel from investing in securities that may be purchased or held by the fund. However, the Code of Ethics, consistent with standards recommended by the Investment Company Institute's Advisory Group on Personal Investing and requirements established by Rule 17j-1 and rules adopted under the Investment Advisers Act of 1940, among other things, prohibits personal securities investments without pre-clearance, imposes time periods during which personal transactions may not be made in certain securities by employees with access to investment information, and requires the timely submission of broker confirmations and quarterly reporting of personal securities transactions. Additional restrictions apply to portfolio managers, traders, research analysts and others involved in the investment advisory process.

The Code of Ethics does not prohibit unaffiliated officers and Trustees from investing in securities that may be held by the fund; however, the Putnam Funds Code of Ethics regulates the personal securities transactions of unaffiliated Trustees of the fund, including limiting the time periods during which they may personally buy and sell certain securities and requiring them to submit reports of personal securities transactions under certain circumstances.

The fund's Trustees, in compliance with Rule 17j-1, approved the Code of Ethics and are required to approve any material changes to the Code of Ethics. The Trustees also provide continued oversight of personal investment policies and annually evaluate the implementation and effectiveness of the Code of Ethics.

· For each fund listed in the table above, all references to Putnam Management in the section PROXY VOTING GUIDELINES AND PROCEDURES and in APPENDIX A - PROXY VOTING GUIDELINES OF THE PUTNAM FUNDS and APPENDIX B - FINANCIAL STATEMENTS, remain unchanged.
