On March 19, 2024, the Board of Trustees of the Trust approved the combination of the Class IA shares of each Portfolio listed below with the Portfolio’s Class IB shares (the “Combination”). Each Portfolio’s Class IA shares and Class IB shares have identical terms and identical expense ratios. The Combination is expected to occur effective after the close of business on June 21, 2024 (the “Effective Date”). The Combination will be effected at the relative net asset value of each share class of the relevant Portfolio. As of the Effective Date, an investor that held Class IA shares of a Portfolio will hold Class IB shares of the same Portfolio having a value equal to the value of the Class IA shares held immediately prior to the Combination. The Combination is not expected to have any federal income tax consequences for investors; investors generally should not realize any gain or loss as a result of the Combination.
