PREPAYMENT CALCULATION METHODOLOGY   
Single Monthly Mortality (SMM): (Voluntary partial and full prepayments + Repurchases)/(Beg Principal Balance - Sched Principal)   
Conditional Prepayment Rate (CPR): 1-((1-SMM)^12)   
PSA Standard Prepayment Model: CPR/(0.02*min(30,WAS))   
Average SMM over period between nth month and mth month (AvgSMMn,m): [(1-SMMn) * (1-SMMn+1) *.......*(1-SMMm)]^(1/months in period n,m)   
Average CPR over period between the nth month and mth month (AvgCPRn,m): 1-((1-AvgSMMn,m)^12)   
Average PSA Approximation over period between the nth month and mth month: AvgCPRn,m/(0.02*Avg WASn,m))   
Average WASn,m: (min(30,WASn)+min(30,WASn+1)+.......+min(30,WASm)/(number of months in the period n,m)   
Weighted Average Seasoning (WAS)   
    
Note: Prepayment rates are calculated since deal issue date and include partial and full voluntary prepayments and repurchases.   
Dates correspond to distribution dates.
