On or about June 10, 2005, the Registrant will cause the issuance and sale of approximately $612,994,300 initial principal amount of Mortgage Pass-Through Certificates, Series 2005-1 (collectively, the “Certificates”) pursuant to a Pooling and Servicing Agreement, dated as of June 1, 2005, among the Registrant, Impac Funding Corporation, as Master Servicer, and Wells Fargo Bank, N.A., as Trustee.

In connection with the sale of the Series 2005-1, Class 1-A-1, Class 1-A-X, Class 2-A, Class 3-A-1, Class 3-A-X, Class 4-A, Class 5-A-1, Class 5-A-2, Class 5-A-3, Class 5-A-4, Class 5-A-5, Class 5-A-6, Class 5-A-7, Class 5-A-X, Class B-1, Class B-2 and Class B-3 Certificates (the “Underwritten Certificates”), the Registrant has been advised by UBS Securities LLC (the “Underwriter”) that the Underwriter has furnished to prospective investors certain yield tables and other computational materials (the “Computational Materials”) with respect to the Underwritten Certificates following the effective date of Registration Statement 333-117991, which Computational Materials are being filed as exhibits to this report.

The Computational Materials have been provided by the Underwriter. The information in the Computational Materials is preliminary and may be superseded by the Prospectus Supplement relating to the Underwritten Certificates and by any other information subsequently filed with the Securities and Exchange Commission.

The Computational Materials were prepared by the Underwriter at the request of certain prospective investors, based on assumptions provided by, and satisfying the special requirements of, such prospective investors. The Computational Materials may be based on assumptions that differ from the assumptions set forth in the Prospectus Supplement. The Computational Materials may not include, and do not purport to include, information based on assumptions representing a complete set of possible scenarios. Accordingly, the Computational Materials may not be relevant to or appropriate for investors other than those specifically requesting them.

In addition, the actual characteristics and performance of the mortgage loans underlying the Underwritten Certificates (the “Mortgage Loans”) may differ from the assumptions used in the Computational Materials, which are hypothetical in nature and which were provided to certain investors only to give a general sense of how the yield, average life, duration, expected maturity, interest rate sensitivity and cash flow characteristics of a particular class of Underwritten Certificates might vary under varying prepayment and other scenarios. Any difference between such assumptions and the actual characteristics and performance of the Mortgage Loans will affect the actual yield, average life, duration, expected maturity, interest rate sensitivity and cash flow characteristics of the Underwritten Certificates.
