The yields were calculated by
1.
determining the monthly discount rates that, when applied to the applicable assumed
streams of cash flows to be paid on the applicable Class, 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 (in the case of interest-bearing Classes), 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 any investment in any Class
when those reinvestment rates are considered.
The information set forth in the following tables was prepared on the basis of the Modeling
Assumptions and the assumptions that (1) the Interest Rate applicable to each Inverse Floating
Rate Class for each Accrual Period following the first Accrual Period will be based on the
indicated level of LIBOR and (2) the purchase price of each Class (expressed as a percentage
of its original Class Principal Balance or Class Notional Balance) plus accrued interest (in the
case of the interest-bearing Classes) is as indicated in the related table. The assumed
purchase price is not necessarily that at which actual sales will occur.
