The Company treats securities sold under agreements to repurchase as collateralized financings. The Company reflects the obligations to repurchase the identical securities sold as liabilities, with the dollar amount of securities underlying the agreements remaining in the asset accounts. Generally, for these types of agreements, there is a requirement that collateral be maintained with a market value equal to or in excess of the principal amount borrowed. As such, the collateral pledged may be increased or decreased over time to meet contractual obligations. The securities underlying the agreements to repurchase are held in collateral accounts with a third-party custodian. At December 31, 2016, the weighted-average remaining maturity of these agreements was 349 days, with maturities as follows:


	Amount
(dollars in thousands)	Maturing
Less than 30 days	$	1,200
30 through 90 days		2,000
Over 90 days		5,951
Total	$	9,151
