Additional report context:
( a ) other changes in expected cash flows may vary from period to period as the firm continues to refine its cash flow model and periodically updates model assumptions . for the years ended december 31 , 2010 and 2009 , other changes in expected cash flows were principally driven by changes in prepayment assumptions , as well as reclassification to the nonaccretable difference . such changes are expected to have an insignificant impact on the accretable yield percentage . the factors that most significantly affect estimates of gross cash flows expected to be collected , and accordingly the accretable yield balance , include : ( i ) changes in the benchmark interest rate indices for variable rate products such as option arm and home equity loans ; and ( ii ) changes in prepayment assump- tions . to date , the decrease in the accretable yield percentage has been primarily related to a decrease in interest rates on vari- able-rate loans and , to a lesser extent , extended loan liquida- tion periods . certain events , such as extended loan liquidation periods , affect the timing of expected cash flows but not the amount of cash expected to be received ( i.e. , the accretable yield balance ) . extended loan liquidation periods reduce the accretable yield percentage because the same accretable yield balance is recognized against a higher-than-expected loan balance over a longer-than-expected period of time. .
