The following disclosure supplements the "Management" section of each Portfolio's Summary Prospectus and Prospectus, the "Additional Information About Management" section of each Portfolio's Prospectus, and the subsection entitled "The Adviser" of the section entitled "Investment Advisory and Other Services" of the Statement of Additional Information:

On November 6, 2025, Brighthouse Financial, Inc. ("Brighthouse"), the parent company of the Portfolio's investment adviser Brighthouse Investment Advisers, LLC ("BIA") and Aquarian Capital LLC ("Aquarian"), a diversified global holding company with a strategic portfolio of insurance and asset management businesses, announced that they have entered into a definitive agreement under which an affiliate of Aquarian will acquire Brighthouse in an all cash transaction. The transaction is subject to approval by Brighthouse's shareholders and customary closing conditions, including receipt of applicable regulatory approvals. Subject to such approvals and the satisfaction of the other conditions, the transaction is expected to be consummated in 2026.

Under the Investment Company Act of 1940, the consummation of the transaction will result in the automatic termination of the Portfolio's investment advisory agreement with BIA, and any related subadvisory agreements, where applicable. As a result, the Trusts' Board of Trustees will be asked to approve new investment advisory agreements between the Trust and BIA and new subadvisory agreements, where applicable. If approved by the Board of Trustees, the investment advisory agreements will be presented to the shareholders of the Portfolio for their approval.
