Fair Value Disclosures [Text Block] | 14. Fair Value of Financial Instruments The Company has established and documented processes for determining fair values. Fair value is based upon quoted market prices, where available. If listed prices or quotes are not available, then fair value is based upon internally developed models that primarily use inputs that are market-based or independently-sourced market parameters, including interest rate yield curves. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of valuation hierarchy are defined as follows: Level 1 Level 2 Level 3 The following describes the valuation methodologies used for the Company’s financial instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. a. Investment Securities Available for Sale (RMBS , U.S. Treasury Securities and CLOs) – b. Investment Securities Available for Sale (CMBS) – c. Multi-Family Loans Held in Securitization Trusts – d. Derivative Instruments – e . Multi-Family CDOs – The following table presents the Company’s financial instruments measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014, respectively, on the Company’s condensed consolidated balance sheets (dollar amounts in thousands): Measured at Fair Value on a Recurring Basis at June 30 , 2015 December 31, 2014 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets carried at fair value Investment securities available for sale: Agency RMBS $ — $ 723,600 $ — $ 723,600 $ — $ 779,505 $ — $ 779,505 Non-Agency RMBS — 1,720 — 1,720 — 1,939 — 1,939 CLOs — — — — — 35,203 — 35,203 U.S. Treasury Securities 10,000 — — 10,000 — — — — Investment securities available for sale held in securitization trusts: CMBS — — 40,217 40,217 — — 38,594 38,594 Multi-family loans held in securitization trusts — — 7,235,328 7,235,328 — — 8,365,514 8,365,514 Derivative assets: TBA Securities — 300,674 — 300,674 — 284,971 — 284,971 Options on U.S. Treasury futures 3 — — 3 92 — — 92 U.S. Treasury futures — — — — 379 — — 379 Interest rate swaps — 233 — 233 — 1,135 — 1,135 Swaptions — 1,907 — 1,907 — 2,273 — 2,273 Total $ 10,003 $ 1,028,134 $ 7,275,545 $ 8,313,682 $ 471 $ 1,105,026 $ 8,404,108 $ 9,509,605 Liabilities carried at fair value Multi-family collateralized debt obligations $ — $ — $ 6,932,092 $ 6,932,092 $ — $ — $ 8,048,053 $ 8,048,053 Derivative liabilities: U.S. Treasury futures 69 — — 69 — — — — Eurodollar futures 2,288 — — 2,288 900 — — 900 Interest rate swaps — 521 — 521 — 232 — 232 Interest rate swap futures 1,533 — — 1,533 331 — — 331 Total $ 3,890 $ 521 $ 6,932,092 $ 6,936,503 $ 1,231 $ 232 $ 8,048,053 $ 8,049,516 The following table details changes in valuation for the Level 3 assets for the six months ended June 30, 2015 and 2014, respectively (amounts in thousands): Level 3 Assets: Six Months Ended June 30, 201 5 201 4 Balance at beginning of period $ 8,404,108 $ 8,203,600 Total gains/(losses) (realized/unrealized) Included in earnings (1) (15,756 ) 318,427 Included in other comprehensive income 422 8,402 Sales (2) (1,075,529 ) — Paydowns (37,700 ) (33,669 ) Sale of real estate owned — (3,385 ) Balance at the end of period $ 7,275,545 $ 8,493,375 (1) Amounts included in interest income from multi-family loans held in securitization trusts , unrealized gain on multi-family loans and debt held in securitization trusts, net and gain on deconsolidation.

As markets and products develop and the pricing for certain products becomes more transparent, the Company continues to refine its valuation methodologies. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company uses inputs that are current as of each reporting date, which may include periods of market dislocation, during which time price transparency may be reduced. This condition could cause the Company’s financial instruments to be reclassified from Level 2 to Level 3 in future periods.

Receivable for securities sold – e . Mortgage loans held for sale (net) – f . First mortgage loan and mezzanine loan and equity investments – g . Financing arrangements – h .
