SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE |
SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE | 9. SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE Securities sold under agreements to repurchase totaled $0.9 million at December 31, 2017 and $0.7 million at December 31, 2016. The repurchase agreements were collateralized by investment securities, of which 52% were U.S. GSE residential collateralized mortgage obligations and 48% were U.S. GSE residential mortgage-backed securities with a carrying amount of $1.8 million at December 31, 2017 and 49% were U.S. GSE residential collateralized mortgage obligations and 51% were U.S. GSE residential mortgage-backed securities with a carrying amount of $2.3 million at December 31, 2016. Securities sold under agreements to repurchase are financing arrangements with $0.9 million maturing during the first quarter of 2018. At maturity, the securities underlying the agreements are returned to the Company. The primary risk associated with these secured borrowings is the requirement to pledge a market value based balance of collateral in excess of the borrowed amount. The excess collateral pledged represents an unsecured exposure to the lending counterparty. As the market value of the collateral changes, both through changes in discount rates and spreads as well as related cash flows, additional collateral may need to be pledged. In accordance with the Company’s policies, eligible counterparties are defined and monitored to minimize exposure. The following table summarizes information concerning securities sold under agreements to repurchase:
