| Repurchase Agreement Borrowings     | Repurchase Agreement BorrowingsSecurities sold under agreements to repurchase ("repurchase agreements") with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by the Company.  Repurchase agreements with customers are included in short-term borrowings on the consolidated condensed balance sheets.All repurchase agreements are subject to terms and conditions of repurchase/security agreements between the Company and the client and are accounted for as secured borrowings.  Our repurchase agreements reflected in short-term borrowings consist of customer accounts and securities which are pledged on an individual security basis.At March 31, 2016 and December 31, 2015, our repurchase agreement borrowings totaled $7.4 million and $7.2 million respectively, and are classified as short-term debt on the consolidated condensed balance sheets.  These borrowings were collateralized with residential mortgage backed securities with a market value of  $16.9 million and $17.1 million at March 31, 2016 and December 31, 2015, respectively. Declines in the value of the collateral would require us to pledge additional securities.  As of March 31, 2016 and December 31, 2015 the Company had $196.5 million and $213.6 million, respectively, of available unpledged securities.The following table presents the carrying value of repurchase agreements by remaining contractual maturity at March 31, 2016 and December 31, 2015:March 31, 2016       (dollars in thousands)Remaining Contractual Maturity of the Agreements Overnight and Continuous 1 - 90 days Over 90 days TotalResidential mortgage-backed securities-GSE$7,352 $— $— $7,352        December 31, 2015       (dollars in thousands)Remaining Contractual Maturity of the Agreements Overnight and Continuous 1 - 90 days Over 90 days TotalResidential mortgage-backed securities-GSE$7,219 $— $— $7,219 |
