Statistical Collateral Summary – Aggregate Collateral

All information on the Mortgage Loans is approximate, includes a portion of the prefunding, and is based off of rolled scheduled balances as of the 12/01/05 cutoff date. Approximately 29.9% of the mortgage loans do not provide for any payments of principal in the first two, three, five or ten years following origination. The final numbers will be found in the prospectus supplement. Thirty-day delinquencies and sixty-day delinquencies will represent less than 1.5% and 0.5% of the Mortgage Loans, respectively. The Original Loan-to-Value (OLTV) ratio displayed in the tables below employs the Combined Loan-to-Value (CLTV) ratio in the case of second liens.

Statistical Collateral Summary – Second Lien Collateral

 All information on the Mortgage Loans is approximate, includes a portion of the prefunding, and is based off of rolled scheduled balances as of the 12/01/05 cutoff date. The final numbers will be found in the prospectus supplement. Thirty-day delinquencies and sixty-day delinquencies will represent less than 1.5% and 0.5% of the Mortgage Loans, respectively. The Original Loan-to-Value (OLTV) ratio displayed in the tables below employs the Combined Loan-to-Value (CLTV) ratio in the case of second liens.

Statistical Collateral Summary – Interest Only Collateral

All information on the Mortgage Loans is approximate, includes a portion of the prefunding, and is based off of rolled scheduled balances as of the 12/01/05 cutoff date. None of the mortgage loans provide for any payments of principal inthe first two, three, five or ten years following origination. The final numbers will be found in the prospectus supplement. Thirty-day delinquencies and sixty-day delinquencies will represent less than 1.5% and 0.5% of the Mortgage Loans, respectively.
