BOSTON--(BUSINESS WIRE)--Each of the Funds listed above announced today that the Fund’s Board of Directors (the “Board”) has approved a plan of liquidation of the Fund. The liquidation pursuant to the plan will be submitted to Fund stockholders for approval at a Special Meeting. The Board recommends that stockholders of each Fund vote for the liquidation of their Fund at the Special Meeting.

As previously announced, effective April 1, 2025, Amundi Asset Management US, Inc., each Fund’s former investment adviser, was combined with Victory Capital Holdings, Inc., the parent company of Victory Capital Management Inc. (“Victory Capital”) (the “Transaction”). In connection with the Transaction, Fund stockholders were asked to approve a new investment advisory agreement with Victory Capital (the “New Agreement”) at a special meeting originally scheduled for March 26, 2025 (the “Postponed Meeting”). Each Fund postponed its meeting because it had not obtained a sufficient number of votes to approve the New Agreement. Because stockholders did not approve the New Agreement prior to the closing of the Transaction, each Fund entered into an interim investment advisory agreement (the “Interim Agreement”) with Victory Capital, which was approved by the Board and took effect upon the closing of the Transaction. The Interim Agreement allows Victory Capital to manage each Fund for up to 150 days following the closing of the Transaction. After considering various options for the Funds, the Board approved, and recommends that stockholders vote for, the liquidation of their Fund.

Each Fund intends to file a proxy statement with the U.S. Securities and Exchange Commission (“SEC”) with respect to the proposal to liquidate the Fund. Copies of each Fund’s proxy statement will also be mailed to each stockholder of record of the Fund. Stockholders are advised to read their Fund’s proxy statement when it is available because it will contain important information. When filed with the SEC, the proxy statement and other documents filed by the Funds will be available free of charge on the SEC website, www.sec.gov.

In light of the Board’s approval of a plan of liquidation for the Fund and its recommendation that stockholders of the Fund vote for liquidation pursuant to the plan, the Postponed Meeting will not be rescheduled.
