Ladies and Gentlemen:

Pursuant to Rule 497(j) under the Securities Act of 1933, as amended (the "Act"), the Registrant certifies that the forms of Prospectus and Statement of Additional Information for the Contract that would have been filed under Rule 497(b) or (c) under the Act would not have differed from that contained in the Amendment. The Amendment was filed electronically with the Securities and Exchange Commission on April 30, 2025 and is the most recent post-effective amendment to the Registrant's registration statement with respect to the Contract.
