Short-Term Borrowings [Abstract] |
Short-Term Borrowings | (9) Short-Term Borrowings Short-term borrowings totaled $316.8 million and $456.0 million at December 31, 2014 and 2013, respectively, and consist of Federal funds purchased and securities sold under repurchase agreements, which generally represent overnight borrowing transactions, and other short-term borrowings, primarily FHLB advances, with original maturities of one year or less. The Company had unused lines of credit with the FHLB available for short-term financing of approximately $958 million and $497 million at December 31, 2014 and 2013, respectively. Borrowings on these lines are secured by FHLB stock, certain securities and one-to-four family first lien mortgage loans. Securities collateralizing repurchase agreements are held in safekeeping by nonaffiliated financial institutions and are under the Company’s control. Information related to short-term borrowings is summarized as follows:
