| Accounting for Certain Loans Acquired in a Purchase     | ACCOUNTING FOR CERTAIN LOANS ACQUIRED IN A PURCHASEThe Bank acquired loans in a purchase during the year ended December 31, 2012.  The following table includes the carrying amount of these loans, which are included in the balance sheet amounts of loans receivable at June 30, 2013 and December 31, 2012.

Evidence of credit quality deterioration as of the purchase date may include information such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Purchased credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality (ASC 310-30) and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan.  Accordingly, an allowance for credit losses related to these loans is not carried over and recorded at the acquisition date.  Management estimated the cash flows expected to be collected at acquisition, which incorporated the estimate of current key assumptions, such as default rates, severity and prepayment speeds. |
