Financial Instruments With Off Balance Sheet Risk [Abstract] |
Financial Instruments Representing Off-Balance-Sheet Credit Risk |
The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business, in order to meet the financing needs of its customers. Those financial instruments consist of unused commitments to extend credit and standby letters of credit. They involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The Company's exposure to credit loss in the event of nonperformance by counterparties for commitments to extend credit and letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and issuing letters of credit as it does for originating loans included on the balance sheet. The following financial instruments represent off-balance-sheet credit risk (dollars in thousands):
