Repurchase Agreements [Abstract] |
Repurchase Agreements Disclosure [Text Block] | Borrowings under Repurchase Agreements The Company pledges certain real estate securities as collateral under repurchase agreements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. Repurchase agreements involve the sale to a counterparty and a simultaneous agreement to repurchase the transferred assets or similar assets from such counterparty at a future date. Repurchase agreements entered into by the Company are accounted for as collateralized borrowings and require the repurchase of the transferred securities at the end of each agreement’s term, which is typically 30 to 180 days. The carrying amount of the Company’s repurchase agreements approximates fair value as the debt is short-term in nature. The Company maintains the beneficial interest in the specific securities pledged during the term of the repurchase agreement and receives the related principal and interest payments. Interest rates on these borrowings are generally fixed based on prevailing rates corresponding to the terms of the borrowings, and interest is paid at the termination of the repurchase agreement at which time the Company may enter into a new repurchase agreement at prevailing market rates with the same counterparty or repay that counterparty and possibly negotiate financing terms with a different counterparty. In response to declines in fair value of pledged securities due to changes in market conditions or the publishing of monthly security paydown factors, counterparties to repurchase agreements will typically make margin calls, whereby the Company will be required to post additional securities as collateral, pay down borrowings or establish cash margin accounts with the counterparties in order to re-establish the agreed-upon collateral requirements. Under the terms of the Company’s master repurchase agreements, or "MRAs," the counterparties may, in certain cases, sell or re-hypothecate the pledged collateral. The Company seeks to have several different counterparties to its repurchase agreements at any given time in order to reduce the exposure to any single counterparty. As of September 30, 2013, the Company had outstanding borrowings under repurchase agreements with seven counterparties. The following table details the Company's outstanding borrowings under repurchase agreements as of September 30, 2013:

Repurchase agreements involving underlying investments that we sold prior to September 30, 2013, for settlement following September 30, 2013, are shown using their original maturity dates even though such repurchase agreements may be expected to be terminated early upon settlement of the sale of the underlying investment. Not included are any repurchase agreements that we may have entered into prior to September 30, 2013 for which delivery of the borrowed funds is not scheduled until after September 30, 2013. As of September 30, 2013, the fair value of Agency RMBS pledged as collateral under outstanding borrowings under repurchase agreements was $1.4 billion. In addition, as of September 30, 2013, the Company held investments with an aggregate value of approximately $1.7 million which was received to satisfy collateral requirements for various repurchase agreements. Collateral pledged under outstanding borrowings include Agency RMBS in the amount of $55.0 million that were sold prior to period end but for which such sale had not yet settled as of September 30, 2013.
