Calculation Methodology: Monthly Default Rate (MDR): sum(Beg Principal Balance of Liquidated Loans)/ sum(Beg Principal Balance). Conditional Default Rate (CDR): 1-((1-MDR)^12) SDA Standard Default Assumption: If WAS is less than or equal to 30 then CDR/(WAS*0.02) else if WAS is greater than 30 and less than or equal to 60 then CDR/0.6 else if WAS is greater than 60 and less than or equal to 120 then CDR/(0.6 - ((WAS-60)*0.0095)) else if WAS is greater than 120 then CDR/0.03 Loss Severity Approximation for current period: sum(Realized Loss Amount)/sum(Beg Principal Balance of Liquidated Loans)
