HOW HAS THE FUND CHANGED?
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 had entered into a definitive agreement for a subsidiary of Franklin Resources to acquire Putnam Holdings in a stock and cash transaction (the “Transaction”). The Transaction was completed on January 1, 2024. As part of the Transaction, your Fund’s then-current investment advisor, Putnam Investment Management, LLC (“Putnam Management”), a wholly-owned subsidiary of Putnam Holdings, and your Fund’s sub-advisors, Putnam Investments Limited (“PIL”) and The Putnam Advisory Company, LLC (“PAC”), indirect, wholly-owned subsidiaries of Putnam Holdings, became indirect, wholly-owned subsidiaries of Franklin Resources. In connection with the Transaction, shareholders of your Fund approved a new management contract with Putnam Management and new sub-advisory contracts with PIL and PAC. The new contracts are identical to the previous contracts, except for the effective dates, initial terms, updates to fund names as necessary to reflect previous name changes, and certain non-substantive changes.
Effective July 15, 2024, Putnam Management transferred its management contract for your Fund to Franklin Advisers, Inc.

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

In connection with the Transaction, shareholders of your Fund approved a new management contract with Putnam Management and new sub-advisory contracts with PIL and PAC.
