I. Notice of Portfolio Substitutions

On or about May 1, 2024 (the “Substitution Date”), in accordance with applicable law, shares of the Existing Funds listed below will be substituted for shares of the Replacement Fund listed below.

Each Existing Fund currently serves as an underlying fund portfolio for a variable investment option and will remain available for investment until the Substitution Date. To the extent that the Replacement Fund is not currently available as an investment option under your contract, the Replacement Fund will be added as an investment option on or before the Substitution Date.

The substitutions will take place at no cost to you and will have no tax consequences to you.

You do not need to take any action.

On the Substitution Date, the Existing Funds will be substituted for the Replacement Fund at relative net asset value, and any remaining policy value you have invested in an Existing Fund will be transferred to the Replacement Fund. Your policy value will not change as a result of the substitutions. The terms of your policy will not be altered in any way, and you will not pay any additional fees or charges as a result of the substitutions.

Beginning on the Substitution Date, the Existing Funds will no longer be available for investment, and we will automatically direct any contributions, automated transfer features such as a Rebalancing program or Dollar Cost Averaging program, or other transactions using an Existing Fund to the Replacement Fund.

At any time prior to the Substitution Date, you may transfer policy value out of an Existing Fund and such transfer or transfers will not incur a transfer fee and will not count against the number of free transfers you are permitted. For

30 days following the Substitution Date, you may transfer policy value out of the Replacement Fund, and such transfer or transfers will not incur a transfer fee and will not count against the number of free transfers you are permitted. From the date of this Supplement until 30 days after the Substitution Date, we will not exercise any reserved contractual rights to impose fees or restrictions on transfers involving an Existing Fund (before the Substitution Date) or the Replacement Fund (after the Substitution Date), other than with respect to market timing.

The Funds may not be available on all contracts. For the investment options currently available to you, please check your Prospectus or contact our Administrative Office referenced in the Prospectuses.
