During 2011, BancShares acquired the rights to service mortgage loans that had previously been sold by United Western. The asset was recorded at its fair value and is being amortized over the remaining estimated servicing life at acquisition of 60 months. In conjunction with the adoption of the change in accounting for QSPEs during 2010, the servicing asset related to a previous asset securitization was eliminated resulting in a decrease to the servicing asset of $304. BancShares does not hedge its mortgage servicing asset.
