Financial Instruments With Off Balance Sheet Risk [Abstract] |
Financial Instruments with Off-Balance-Sheet Risk | Note 8 – Financial Instruments with Off-Balance-Sheet 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 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):
|  | March 31, 2013 |  | December 31, 2012 |
Commitments to extend credit |  | $ | 313,907 |  | $ | 225,400 |
Standby letters of credit |  | $ | 6,727 |  | $ | 6,690 |
Commercial letters of credit |  | $ | 8,536 |  | $ | 8,539 |
Commitments to extend credit consist primarily of the following: Unfunded home equity lines of credit; commercial real estate construction loans, which are established under standard underwriting guidelines and policies and are secured by deeds of trust, with disbursements made over the course of construction; commercial revolving lines of credit, which have a high degree of industry diversification; the unused portions of mortgage warehouse lines of credit; and the unused portions of formalized (disclosed) deposit account overdraft lines. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments are expected to expire without being drawn upon, the unused portions of committed amounts do not necessarily represent future cash requirements. Standby letters of credit are generally unsecured and are issued by the Company to guarantee the performance of a customer to a third party, while commercial letters of credit represent the Company’s commitment to pay a third party on behalf of a customer upon fulfillment of contractual requirements. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The Company is also utilizing a $69 million letter of credit issued by the Federal Home Loan Bank on the Company’s behalf as security for certain deposits. The letter of credit is backed by specific loans which are pledged to the Federal Home Loan Bank by the Company.
