Changes In The Amount Of Accretable Yield | The following table documents changes to the amount of accretable yield for the years ended December 31, 2012, and 2011. For acquired loans, improved cash flow estimates and receipt of unscheduled loan payments result in the reclassification of nonaccretable yield to accretable yield. During 2012, the improved ability to estimate cash flows due to expanded use of an acquired loan accounting system also contributed to significant increases in accretable yield. Accretable yield resulting from the improved ability to estimate future cash flows generally does not represent amounts previously identified as nonaccretable difference.
