Decrement Tables The decrement tables set forth below illustrate the percentage of the Original Class Princi- pal Balance (or, in the case of the Notional Class, the original Class Notional Balance) that would  remain  outstanding  following  the  distribution  made  each  specified  month  for  each Regular Class, based on the assumption that the related 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 percentages set forth in the following decrement tables have been rounded to the nearest whole percentage (including rounding down to zero). The decrement tables also indicate the Weighted Average Life of each Class under each CPR Prepayment Assumption Rate and the PLD percentage rates indicated above for the Trust PLC Mortgage Loans and the Trust CLC Mortgage Loans. The Weighted Average Life of each Class is calculated by: (a)  multiplying  the  net  reduction,  if  any,  of  the  Class  Principal  Balance  (or  the  net reduction  of  the  Class  Notional  Balance,  in  the  case  of  the  Notional  Class)  from  one Distribution Date to the next Distribution Date by the number of years from the date of issuance thereof to the related Distribution Date, (b)  summing the results, and (c)  dividing the sum by the aggregate amount of the assumed net reductions in principal balance or notional amount, as applicable, referred to in clause (a). The Weighted Average Lives are likely to vary, perhaps significantly, from those set  forth  in  the  tables  below  due  to  the  differences  between  the  actual  rate  of prepayments on the Mortgage Loans underlying the Ginnie Mae Multifamily Certifi- cates and the Modeling Assumptions. The information shown for the Notional Class is for illustrative purposes only, as a Notional Class  is  not  entitled  to  distributions  of  principal  and  has  no  weighted  average  life.  The weighted average life shown for the Notional Class has been calculated on the assumption that a reduction in the Class Notional Balance thereof is a distribution of principal.
