The Company extends standby letters of credit to its customers in the normal course of business. The standby letters of credit are generally short-term. As of June 30, 2013, the Company's maximum potential obligation under standby letters of credit was $67.9 million compared to $68.7 million at December 31, 2012. Management uses the same credit policies to extend standby letters of credit that it uses for on-balance sheet lending decisions and may require collateral to support standby letters of credit based upon its evaluation of the counterparty. Management does not anticipate any significant losses as a result of these transactions, and has determined that the fair value of standby letters of credit is not significant.</font></div></div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for each guarantee obligation, or each group of similar guarantee obligations, including (a) the nature of the guarantee, including its term, how it arose, and the events or circumstances that would require the guarantor to perform under the guarantee; (b) the maximum potential amount of future payments (undiscounted) the guarantor could be required to make under the guarantee; (c) the current carrying amount of the liability, if any, for the guarantor's obligations under the guarantee; and (d) the nature of any recourse provisions under the guarantee, and any assets held either as collateral or by third parties, and any relevant related party disclosure.
