Effective on or about the close of business on December 5, 2025 (the “Liquidation Date”), due to the liquidation of the underlying portfolio listed below (the “Portfolio”), the subaccount (the “Subaccount”) will be liquidated.

If you have contract value allocated to the Subaccount on the Liquidation Date, shares of the Portfolio held for you in the Subaccount will be exchanged for shares of the Transamerica BlackRock Government Money Market VP (the “Money Market Portfolio”), of equal value on the Liquidation Date, and held in the Transamerica BlackRock Government Money Market VP subaccount (the “Money Market Subaccount”).

As of the start of business on the Liquidation Date, you will no longer be able to use automated transfer features such as Rebalancing Program or Dollar Cost Averaging with the Subaccount for the Portfolio. If you are using an automated transfer feature such as Rebalancing Program or Dollar Cost Averaging with the Subaccount for the Portfolio, you should contact us immediately to make alternate arrangements. If you do not make alternate arrangements any subsequent allocations to the Subaccount for the Portfolio will be directed to the Money Market Subaccount.
