Fitch Rates $479MM RBSGC MLT Mtge P-T Ctfs, Series 2007-A.

NEW YORK -- Fitch rates RBSGC Mortgage Loan Trust $479 million mortgage loan pass-through certificates, series 2007-A, as follows:

--$447 million classes 1-A-1, 2-A-1 through 2-A-5, 3-A-1, 3-A-2, X, PO, and R 'AAA';

--$13.7 million class B-1 'AA+';

--$5.5 million class

--$4.8 million class B-3 'A';

--$3.6 million class B-4 'BBB';

--$2.4 million class B-5 'BB' (144A);

--$1.9 million class B-6 'B' (144A).

The 'AAA' rating on the senior certificates reflects the 7% total credit enhancement provided by the 2.6% class B-1, 1.4% class B-2, 1% class B-3, 0.75% class B-4, privately offered 0.5% class B-5, and privately offered 0.4% class B-6, as well as the non-rated, privately offered 0.35% class B-7.

Fitch believes that the amount of credit enhancement will be sufficient to cover credit losses, including limited bankruptcy, fraud, and special hazard losses. In addition, the ratings reflect the quality of the mortgage collateral, the strength of the legal and financial structures, and the servicing capabilities of Wells Fargo Bank, N.A. (rated 'RMS1' by Fitch).

The aggregate mortgage pool trust consists of 1,921 fixed-rate, conventional, first lien residential mortgage loans, substantially all of which have original terms to stated maturity of 30 years. As of the cut-off date (Jan. 1, 2007), the mortgages have an aggregate principal balance of approximately $480,662,574. The mortgage pool has a weighted average original loan-to-value ratio (OLTV) of 73.38%, a weighted average coupon (WAC) of 6.904%, and a weighted average remaining term (WAM) of 352.

None of the mortgage loans are 'high cost' loans as defined under any local, state, or federal laws. For additional information on Fitch's rating criteria regarding predatory lending legislation, please see the press release issued May 1, 2003 entitled 'Fitch Revises Rating Criteria in Wake of Predatory Lending Legislation' available on the Fitch Ratings web site at www.fitchratings.com.

The mortgage loans were originated or acquired by Wells Fargo Bank, N.A. (61.43% of the mortgage pool), First Magnus Financial Corporation (19.33% of the mortgage pool), and MortgageIT, Inc. (19.24% of the mortgage pool).

Greenwich Capital Acceptance, Inc., a special purpose corporation, deposited the loans in the trust, which issued the certificates. For federal income tax purposes, an election will be made to treat the trust fund as multiple real estate mortgage investment conduits (REMICs).
