100% of the Prospectus Prepayment Curve (“PPC”) for the fixed rate collateral assumes 4.60% Constant Prepayment Rate (“CPR”) in the first month of the life of the mortgage loans, which then increases by approximately 1.67% CPR in each of the following 11 months. In month 12, and thereafter, 100% PPC for the fixed rate collateral assumes 23.00% CPR. 100% PPC for the adjustable rate loans assumes 8.00% CPR in the first month of the life of the mortgage loans, which then increases by approximately 2.00% CPR in each of the following 11 months. In month 12 through 22, 100% PPC for the adjustable rate loans assumes 30.00% CPR. In month 23 through 27, 100% PPC for the adjustable rate loans assumes 55.00% CPR. In month 28 and thereafter, 100% PPC for the adjustable rate loans is assumed to remain constant at 35.00% CPR. The bonds are priced to call at 100% of the PPC and assuming one-month LIBOR and six-month LIBOR are 3.80% and 4.10%, respectively. The initial class principal balances of the certificates are subject to a variance of no more than plus or minus 5% prior to their issuance.
