Financial Instruments with Off-Balance Sheet Risk [Abstract] |
Financial Instruments with Off-Balance Sheet Risk | 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 to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. At March 31, 2018, commitments to extend credit to existing and new borrowers approximated $2,216.5 million, which included $656.7 million on unused credit card lines and $795.7 million with commitment maturities beyond one year. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. At March 31, 2018, the Company had outstanding standby letters of credit of $50.2 million. The estimated fair value of the obligation undertaken by the Company in issuing the standby letters of credit is included in other liabilities in the Company’s consolidated balance sheet.
