Collateral Positions

The Company pledges securities or cash as collateral to its counterparties pursuant to its borrowings under repurchase agreements and for initial margin payments on centrally cleared Swaps. In addition, the Company receives securities or cash as collateral pursuant to financing provided under reverse repurchase agreements.  The Company exchanges collateral with its counterparties based on changes in the fair value, notional amount and term of the associated repurchase agreements and Swap contracts, as applicable.  In connection with these margining practices, either the Company or its counterparty may be required to pledge cash or securities as collateral. When the Company’s pledged collateral exceeds the required margin, the Company may initiate a reverse margin call, at which time the counterparty may either return the excess collateral, or provide collateral to the Company in the form of cash or equivalent securities.

The Company’s assets pledged as collateral are described in Notes 2(f) - Restricted Cash, 5(c) - Derivative Instruments and 6 - Repurchase Agreements. The total fair value of assets pledged as collateral with respect to the Company’s borrowings under repurchase agreements and derivative hedging instruments was $9.4 billion and $8.1 billion at December 31, 2018 and 2017, respectively. An aggregate of $33.1 million and $19.6 million of accrued interest on those assets had also been pledged as of December 31, 2018 and 2017, respectively. In addition, at December 31, 2017, $688.1 million of Legacy Non-Agency MBS were pledged as collateral and $504.1 million of U.S. Treasury securities were held as collateral in connection with contemporaneous repurchase and reverse repurchase agreements entered into with a single counterparty.
