HOW HAS THE FUND CHANGED?

Effective July 15, 2026, the Fund’s name changed to “Franklin Multi-Asset Income Fund”.

Effective August 1, 2026 (the “Effective Date”), The Putnam Advisory Company, LLC (“PAC”), a sub-advisor to the Fund prior to the Effective Date, and an indirect wholly-owned subsidiary of Franklin Templeton, Inc. (formerly Franklin Resources, Inc.), transferred its investment personnel and the assets and liabilities related to its Singapore branch’s investment management business to Templeton Asset Management Ltd. (“TAML”), also an indirect wholly-owned subsidiary of Franklin Templeton, Inc. (the “Reorganization”). As of the Effective Date, PAC investment professionals in its Singapore branch became employees of TAML, and the sub-advisory agreement between Franklin Advisers, Inc. (the “Investment Manager”) and PAC with respect to the Fund was transferred to TAML pursuant to an assignment and assumption agreement (such sub-advisory agreement, as modified by the assignment and assumption agreement, the “New Sub-Advisory Contract”). In connection with the Reorganization, the Fund’s Trustees approved the New Sub-Advisory Contract between the Investment Manager and TAML, pursuant to which TAML became a sub-advisor of the Fund on the Effective Date.

The changes described above are not expected to change the Fund’s investment strategy or the way in which the Fund’s assets are managed in any material way, are not expected to materially change the nature or level of services provided to the Fund, and will not result in an increase in the fees payable by the Fund to the Investment Manager.

For more complete information, you may review the Fund’s current prospectus and any applicable supplements and the Fund’s next prospectus, which we expect to be available by January 1, 2027, at https://www.franklintempleton.com/regulatory-fund-documents or upon request at (800) 225-1581 or funddocuments@putnam.com.

HOW HAS THE FUND CHANGED?

Effective July 15, 2026, the Fund’s name changed to “Franklin Multi-Asset Income Fund”.

Effective August 1, 2026 (the “Effective Date”), The Putnam Advisory Company, LLC (“PAC”), a sub-advisor to the Fund prior to the Effective Date, and an indirect wholly-owned subsidiary of Franklin Templeton, Inc. (formerly Franklin Resources, Inc.), transferred its investment personnel and the assets and liabilities related to its Singapore branch’s investment management business to Templeton Asset Management Ltd. (“TAML”), also an indirect wholly-owned subsidiary of Franklin Templeton, Inc. (the “Reorganization”). As of the Effective Date, PAC investment professionals in its Singapore branch became employees of TAML, and the sub-advisory agreement between Franklin Advisers, Inc. (the “Investment Manager”) and PAC with respect to the Fund was transferred to TAML pursuant to an assignment and assumption agreement (such sub-advisory agreement, as modified by the assignment and assumption agreement, the “New Sub-Advisory Contract”). In connection with the Reorganization, the Fund’s Trustees approved the New Sub-Advisory Contract between the Investment Manager and TAML, pursuant to which TAML became a sub-advisor of the Fund on the Effective Date.

The changes described above are not expected to change the Fund’s investment strategy or the way in which the Fund’s assets are managed in any material way, are not expected to materially change the nature or level of services provided to the Fund, and will not result in an increase in the fees payable by the Fund to the Investment Manager.

(c) N/A

(d) N/A

(f) Pursuant to Item 19(a) (1), the Registrant is attaching as an exhibit a copy of its code of ethics that applies to its principal executive officers and principal financial and accounting officer.

The Board of Trustees of the Registrant has determined that Warren Lowell, Kenneth Tanji and Manoj P. Singh possess the technical attributes identified in Item 3 to Form N-CSR to qualify as “audit committee financial experts,” and has designated Warren Lowell, Kenneth Tanji and Manoj P. Singh as the Audit Committee’s financial experts. Warren Lowell, Kenneth Tanji and Manoj P. Singh are “independent” Trustees pursuant to paragraph (a)(2) of Item 3 to Form N-CSR.

Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an “expert” for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification. The designation or identification of a person as an audit committee financial expert does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.

(a) Audit Fees. The aggregate fees billed in the last two fiscal years ending August 31, 2025 and August 31, 2026 (the “Reporting Periods”) for professional services rendered by the Registrant’s principal accountant (the “Auditor”) for the audit of the Registrant’s annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $101,148 in August 31, 2025 and $85,390 in August 31, 2026.

(b) Audit-Related Fees. The aggregate fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant’s financial statements were $0 in August 31, 2025 and $0 in August 31, 2026.

The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning (“Tax Services”) were $21,408 in August 31, 2025 and $21,408 in August 31, 2026. These services consisted of (i) review or preparation of U.S. federal, state, local and excise tax returns; (ii) U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments, and (iii) tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

There were no fees billed for tax services by the Registrant’s investment adviser and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Registrant (“Service Affiliates”) during the Reporting Periods that required pre-approval by the Audit Committee.

(d) All Other Fees. The aggregate fees billed in the Reporting Periods for products and services provided by the Auditor to the Registrant, other than the services reported in paragraphs (a) through (c) of this item, were $0 in August 31, 2025 and $0 in August 31, 2026.

There were no other non-audit services rendered by the Auditor to the Service Affiliates requiring pre-approval by the Audit Committee in the Reporting Periods.

(e) Audit Committee’s pre–approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

Pre-Approval Policies of the Audit, Compliance and Risk Committee. The Audit, Compliance and Risk Committee of the Putnam funds has determined that, as a matter of policy, all work performed for the funds by the funds’ independent auditors will be pre-approved by the Committee itself and thus will generally not be subject to pre-approval procedures.

The Audit, Compliance and Risk Committee also has adopted a policy to pre-approve the engagement by the fund’s investment manager and certain of its affiliates of the fund’s independent auditors, even in circumstances where pre-approval is not required by applicable law. Any such requests by the fund’s investment manager or certain of its affiliates are typically submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work should be performed by that particular audit firm as opposed to another one. In reviewing such requests, the Committee considers, among other things, whether the provision of such services by the audit firm are compatible with the independence of the audit firm.

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) Non-audit fees billed by the Auditor for services rendered to the Registrant and the Service Affiliates during the reporting period were $583,796 in August 31, 2025 and $1,557,011 in August 31, 2026.

(h) Yes. The Registrant’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Auditor’s independence. All services provided by the Auditor to the Registrant or to the Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

(j) Not applicable

Not applicable.
