MOODY'S RATES STRUCTURED ASSET SECURITIES CORP TRUST 2005-4XS Aaa.
Approximately $760 Million of Mortgage-Backed Securities Rated.
New York, June 15, 2005 -- Moody's Investors Service has assigned a Aaa rating to the senior certificates
issued by Structured Asset Securities Corporation ("SASCO") 2005-4XS.
Moody's has also assigned ratings ranging from Aa1 to Baa2 to the mezzanine
and subordinate certificates of the same transaction.
The securitization is backed by fixed-rate Alt-A mortgage
loans originated mostly by Aurora Loan Services, Inc. ("Aurora")
(81.9%) and Chase Home Finance LLC (11.9%).
The ratings are based primarily on the credit quality of the loans,
and on the protection from subordination, overcollateralization
(OC), excess spread, and borrower-paid mortgage insurance.
The Class 1-A2A, Class 1-A4B, Class 1-A5A
and Class 3-A5 certificates have the benefit of a certificate guaranty
insurance policy from Ambac Assurance Corporation, but the ratings
of these certificates were assigned without regard to this insurance policy.
Aurora will master service the loans in this transaction.
