Repurchase Agreements [Abstract] |
Repurchase Agreements, Resale Agreements, Securities Borrowed, and Securities Loaned Disclosure [Text Block] | REPURCHASE AGREEMENTS We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and secure long-term funding needs. Repurchase agreements are transactions whereby we offer to sell to a counterparty an undivided interest in an eligible security at an agreed upon purchase price, and which obligates BancShares to repurchase the security on an agreed upon date at an agreed upon repurchase price plus interest at an agreed upon rate. Securities sold under agreements to repurchase are recorded at the amount of cash received in connection with the transaction and are reflected as short-term borrowings on the Consolidated Balance Sheets. We monitor collateral levels on a continuous basis and maintain records of each transaction specifically describing the applicable security and the counterparty’s fractional interest in that security, and we segregate the security from its general assets in accordance with regulations governing custodial holdings of securities. The primary risk with our repurchase agreements is market risk associated with the investments securing the transactions, as we may be required to provide additional collateral based on fair value changes of the underlying investments. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. The carrying value of available for sale investment securities pledged as collateral under repurchase agreements totaled $825.6 million and $418.3 million at September 30, 2015 and December 31, 2014, respectively. The remaining contractual maturity of the securities sold under agreements to repurchase by class of collateral pledged included in short-term borrowings in the Consolidated Balance Sheets as of September 30, 2015 and December 31, 2014 is presented in the following tables.
