The yields were calculated by: 1. determining the monthly discount rates that, when applied to the assumed streams of cash flows to be paid on Class IO, would cause the discounted present value of the assumed streams of cash flows to equal the assumed purchase price of that Class plus accrued interest, and 2. converting the monthly rates to corporate bond equivalent rates. These calculations do not take into account variations that may occur in the interest rates at which investors may be able to reinvest funds received by them as distributions on their Securities and consequently do not purport to reflect the return on investment in any Class when those reinvestment rates are considered. The information set forth in the following table was prepared on the basis of the Modeling Assumptions and the assumption that the purchase price of Class IO (expressed as a percentage of its original Class Notional Balance) plus accrued interest is as indicated in the table.  The assumed purchase price is not necessarily that at which actual sales will occur. Sensitivity of Class IO to Prepayments Assumed Price 5.57985%* 5% 15% 25% 40% CPR Prepayment Assumption Rates 10.4% 11.3% 14.3% 19.4% * The price does not include accrued interest. Accrued interest has been added to the price in calculating the yields set forth in the table.
