On October 10, 2024, TD Bank N.A. and its parent company, TD Bank US Holding Company (collectively, "TD Bank") pleaded guilty to various violations of federal anti-money laundering laws. The Funds' sub-adviser, Epoch Investment Partners, Inc. ("Epoch"), is an affiliate of TD Bank. Epoch has informed the Funds that the conduct underlying TD Bank's guilty plea does not relate to Epoch, any Epoch employee or Epoch's investment advisory business. Nevertheless, because of its affiliation with TD Bank, Epoch must obtain an exemptive order from the Securities and Exchange Commission (the "SEC") to remain eligible to serve as an investment adviser to registered investment companies. Epoch is seeking an order from the SEC to permit Epoch to continue to provide sub-advisory services to the Funds and other registered investment companies notwithstanding TD Bank's plea. While there can be no assurance that the requested order will be granted, the SEC has granted this type of relief in the past. In the meantime, Epoch will continue to provide sub-advisory services to the Funds, consistent with its fiduciary duty.

PLEASE RETAIN THIS SUPPLEMENT FOR YOUR FUTURE REFERENCE.
