The resecuritization trust consists of one seasoned senior residential mortgage-backed security (RMBS). The AAA rating on the Class A-1 certificates reflects a 50% credit enhancement provided by Class A-2 via subordination. The ratings also reflect the quality of the underlying security, Citigroup Mortgage Loan Trust 2007-AR8 Class 1-A1A. Certain classes of certificates (Initial Exchangeable Certificates) are exchangeable for certain other classes of certificates (Exchangeable Certificates) and vice versa, in the combinations described in Schedule A of the private placement memorandum.

DBRS does not rate Class A-2 and its exchangeable certificates in this transaction.

Interest and principal payments on the certificates will be made generally on the 25th day of each month commencing in January 2010. Interest payments will be distributed on a pro rata basis to the certificates, and principal will be distributed on a sequential basis to the certificates, in the order of priority specified in the private placement memorandum, until the principal balances thereof are reduced to zero.

Any losses realized from the underlying securities will be allocated in a reverse numerical order to the certificates.

The Trust is a resecuritization consisting of one senior RMBS, Citigroup Mortgage Loan Trust 2007-AR8 Class 1-A1A, which is backed by a pool of Alt-A, fixed-rate, first-lien, one- to four-family residential mortgages.
