Amundi Asset Management US, Inc. (the “Adviser”), the Fund’s investment adviser, is currently an indirect, wholly-owned subsidiary of Amundi.  On July 9, 2024, Amundi announced that it had entered into a definitive agreement with Victory Capital Holdings, Inc. (“Victory Capital”) to combine the Adviser with Victory Capital, and for Amundi to become a strategic shareholder of Victory Capital (the “Transaction”).  Victory Capital is headquartered in San Antonio, Texas.  The closing of the Transaction is subject to certain regulatory approvals and other conditions.  There is no assurance that the Transaction will close.
The closing of the Transaction would cause the Fund’s current investment advisory agreement with the Adviser to terminate.  Under the terms of the Transaction, the Fund’s Board of Trustees will be asked to approve a reorganization of the Fund into a corresponding, newly established Victory Fund advised by Victory Capital Management Inc., an affiliate of Victory Capital.  The proposed reorganization of the Fund would be sought in connection with the closing of the Transaction.  If approved by the Board, the proposal to reorganize the Fund will be submitted to the shareholders of the Fund for their approval.  There is no assurance that the Board or the shareholders of the Fund will approve the proposal to reorganize the Fund.

Material Fund Changes
Amundi Asset Management US, Inc. (the “Adviser”), the Fund’s investment adviser, is currently an indirect, wholly-owned subsidiary of Amundi.  On July 9, 2024, Amundi announced that it had entered into a definitive agreement with Victory Capital Holdings, Inc. (“Victory Capital”) to combine the Adviser with Victory Capital, and for Amundi to become a strategic shareholder of Victory Capital (the “Transaction”).  Victory Capital is headquartered in San Antonio, Texas.  The closing of the Transaction is subject to certain regulatory approvals and other conditions.  There is no assurance that the Transaction will close.
The closing of the Transaction would cause the Fund’s current investment advisory agreement with the Adviser to terminate.  Under the terms of the Transaction, the Fund’s Board of Trustees will be asked to approve a reorganization of the Fund into a corresponding, newly established Victory Fund advised by Victory Capital Management Inc., an affiliate of Victory Capital.  The proposed reorganization of the Fund would be sought in connection with the closing of the Transaction.  If approved by the Board, the proposal to reorganize the Fund will be submitted to the shareholders of the Fund for their approval.  There is no assurance that the Board or the shareholders of the Fund will approve the proposal to reorganize the Fund.
