Fitch rates Wells Fargo mortgage pass-through
certificates, series 2006-9 as follows:
-- $1,242,220,224 classes I-A-1 to I-A-35, II-A-1, II-A-2, A-PO, and A-R (senior certificates) 'AAA';
-- $21,997,000 class B-1 'AA+';
-- $12,292,000 class B-2 'AA';
-- $7,116,000 class B-3 'A';
-- $3,881,000 class B-4 'BBB';
-- $2,587,000 class B-5 'BB';
-- $1,940,000 class B-6 'B';
-- $1,946,189 class B-7 'NR';
The 'AAA' ratings on the senior certificates reflect the 4% subordination provided by the 1.70% class B-1, the 0.95% class B-2, the 0.55% class B-3, the 0.30% class B-4, the 0.20% privately offered class B-5, 0.15% privately offered class B-6 and the 0.15% privately offered class B-7. The ratings on the class B-1, B-2, B-3, B-4, B-5 and B-6 certificates are based on their respective subordination. Class B-7 is not rated by Fitch.
Fitch believes the amount of credit enhancement available will be sufficient to cover credit losses. The ratings also reflect the high quality of the underlying collateral, the integrity of the legal and financial structures, and the primary servicing capabilities of Wells Fargo Bank, N.A. ((WFB); rated 'RPS1' by Fitch).
The transaction consists of two groups of 2,428 fully amortizing, fixed interest rate, first lien mortgage loans, with an original weighted average term to maturity (WAM) of approximately 30 years. The aggregate unpaid principal balance of the pool is $1,293,979,414 as of July 1, 2006 (the cut-off date), and the average principal balance is $532,940. The weighted average original loan-to-value ratio (OLTV) of the loan pool is approximately 71.59%; 1.31% of the loans have an OLTV greater than 80%. The weighted average coupon (WAC) of the mortgage loans is 6.501%, and the weighted average FICO score is 746. Cash-outs and rate/term refinance represent 20.03% and 13.16%, respectively. The states that represent the largest geographic concentration are California (27.85%), Virginia (7.40%), New York (6.12%) and Maryland (6.06%). All other states represent less than 5% of the outstanding balance of the pool.
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, see the press release 'Fitch Revises Rating Criteria in Wake of Predatory Lending Legislation,' dated May 1, 2003, available on the Fitch Ratings web site at www.fitchratings.com.
All of the mortgage loans were generally originated in conformity with underwriting standards of WFB. WFB sold the loans to Wells Fargo Asset Securities Corporation (WFASC), a special purpose corporation, who deposited the loans into the trust. The trust issued the certificates in exchange for the mortgage loans. WFB will act as servicer and custodian, and HSBC Bank USA, National Association will act as trustee. Elections will be made to treat the trust as two separate real estate mortgage investment conduit (REMICs) for federal income tax purposes.
