                     REMOVAL OF SECURITIES FROM REGISTRATION


        This Amendment No. 19 to Form S-1 (File No.333-65953) (the "Registration
Statement") is being filed pursuant to Item 512(a)(3) of Regulation S-K under
the Securities Act of 1933, as amended, to remove from registration those market
value adjustment ("MVA") interests of the Registrant that were previously
registered by the Registration Statement and that were not sold in the offering.

         The Registrant has issued an endorsement (the "MVA Endorsement") to
each Contract that contains an MVA Fixed Account option registered by the
Registration Statement. Effective May 2, 2005 (the "Endorsement Effective
Date"), the MVA Endorsement modifies each Contract's MVA formula so that the
application of the MVA formula after the Endorsement Effective Date results in
MVA interests that no longer constitute securities requiring registration.
Registrant will no longer file any amendments to this Registration Statement.

        The Registrant does not intend to use the Registration Statement to sell
any additional securities. Therefore, the offering is being terminated as of the
Endorsement Effective Date. Registrant hereby removes from registration any
previously registered securities that remain unsold under the Registration
Statement.



                                   SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-1 and has duly caused this Amendment to the
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Los Angeles, State of California, on December
20, 2005.
