The outstanding repo agreements at March 31, 2017 were fixed rate and collateralized by GSE securities, of which 82% were residential mortgage-backed securities and 18% were obligations of GSEs. Securities collateralizing these agreements are classified as encumbered securities in the consolidated statements of financial condition. The amount of excess collateral required is governed by each individual contract. 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 our policies, criteria for eligible counterparties has been established and excess collateral pledged is monitored to minimize our exposure.
