Special terms not defined herein have the meanings ascribed to them in the Prospectus.

The Portfolios will liquidate and dissolve on or about December 15, 2025, (the "Liquidation Date") and will no longer be available investment allocation options. Effective October 31, 2025, the Vest VI Funds will be closed to new investments and effective December 1, 2025 will be closed to subsequent investments. Until the Liquidation Date, Portfolios' shareholders may continue to reinvest dividends and distributions in the Portfolios or redeem their shares.

Prior to the Liquidation Date, you may change your premium payment allocations instructions and transfer your allocations of contract value to any other available variable investment options offered under the terms of your contract. Any contract value in the Contract that is allocated to the Portfolio at the close of business on the Liquidation Date will be transferred to the Fidelity VIP Government Money Market Portfolio (Service Class 2) (the "Fund"). For 30 days following the Liquidation Date, you may transfer a portion or the entire amount of any of your accumulation value transferred to the Fund to any other available variable investment options free of charge. Transfers made due to the closure and liquidation of the Portfolio will not be counted with regard to the maximum number of free transfers and the limits on the number of transfers under your contract.
