Slow rates of prepayments on the Mortgage Loans are likely to coincide with periods of high prevailing interest rates. •   During  periods  of  high  prevailing  interest  rates,  the  amount  of  principal  payments available to an investor for reinvestment at those high rates may be relatively low. The Mortgage Loans will not prepay at any constant rate until maturity, nor will all of the Mortgage Loans prepay at the same rate at any one time. The timing of changes in the rate of prepayments may affect the actual yield to an investor, even if the average rate of principal prepayments is consistent with the investor's expectation. In general, the earlier a prepayment of principal on the Mortgage Loans, the greater the effect on an investor's yield. As a result, the effect on an investor's yield of principal prepayments occurring at a rate higher (or lower) than the rate anticipated by the investor during the period immediately following the Closing Date is not likely to be offset by a later equivalent reduction (or increase) in the rate of principal prepayments. Payment Delay: Effect on Yields The effective yield on any Class will be less than the yield otherwise produced by its Interest Rate and purchase price because on any Distribution Date, 30 days' interest will be payable on (or added to the principal amount of) that Class even though interest began to accrue approximately 46 days earlier. Yield Table The following table shows the pre-tax yields to maturity on a corporate bond equivalent basis of Class IO based on the assumption that the Trust PLC Mortgage Loans prepay at the CPR Prepayment Assumption Rates and 100% PLD and the Trust CLC Mortgage Loans prepay at 0% CPR and 0% PLD until the Trust CLCs convert to Ginnie Mae Project Loan Certificates after which they prepay at the CPR Prepayment Assumption Rates and 100% PLD. The Mortgage Loans will not prepay at any constant rate until maturity. Moreover, it is likely that the Mortgage Loans will experience actual prepayment rates that differ from those of the Modeling Assumptions. Therefore, the actual pre-tax yield of Class IO may differ from those shown in the table even if Class IO is purchased at the assumed price shown. 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) is as indicated in the table. The assumed purchase price is not necessarily that at which actual sales will occur. S-33
