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 September 30, 2016, the weighted-average remaining maturity of these agreements was 441 days, with maturities as follows:
