Counterparty Risk and Concentration

15. Counterparty Risk and Concentration

      Counterparty risk is the risk that counterparties may fail to fulfill their obligations, including their inability to post additional collateral in circumstances where their pledged collateral value becomes inadequate. The Company attempts to manage its exposure to counterparty risk through diversification, use of financial instruments and monitoring the creditworthiness of counterparties.

      The Company finances the acquisition of a significant portion of its residential mortgage loans, RMBS and Other Investment Securities with repurchase agreements. In connection with these financing arrangements, the Company pledges its residential mortgage loans and securities as collateral to secure the borrowings. The amount of collateral pledged will typically exceed the amount of the borrowings (i.e., the haircut) such that the borrowings will be over-collateralized. As a result, the Company is exposed to the counterparty if, during the term of the repurchase agreement financing, a lender should default on its obligation and the Company is not able to recover its pledged assets. The amount of this exposure is the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged by the Company to the lender including accrued interest receivable on such collateral.

      As explained in the notes above, while the Company engages in repurchase financing activities with several financial institutions, the Company maintains custody accounts with two custodians at June 30, 2014. There is no guarantee that these custodians will not become insolvent. While there are certain regulations that seek to protect customer property in the event of a failure, insolvency or liquidation of a custodian, there is no certainty that the Company would not incur losses due to its assets being unavailable for a period of time in the event of a failure of a custodian that has custody of the Company's assets. Although management monitors the credit worthiness of its custodians, such losses could be significant and could materially impair the ability of the Company to achieve its investment objective.
