Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block] | NOTE 4 AVAILABLE-FOR-SALE SECURITIES With effect from January 1, 2015, ASU 2014-11 changed the basis on which the Company accounts for repurchase to maturity transactions and linked repurchase financings to be consistent with the basis on which the Company accounts for secured borrowings. Accordingly, the assets and repurchase agreements that encompass linked transactions that were previously accounted for on a net basis and recorded as a forward purchase (derivative) contract are now bifurcated, and the gross amounts are reported in available-for-sale securities and repurchase agreements separately. Consequently, the Company’s GAAP financial statements as of and for the period ended June 30, 2015 are not directly comparable to prior period GAAP financials. The following table presents the Company’s AFS investment securities by collateral type at fair value as of June 30, 2015 and December 31, 2014: June 30, 2015 December 31, 2014 Mortgage-backed securities: Agency Federal Home Loan Mortgage Corporation $ 89,429,826 $ 162,344,627 Federal National Mortgage Association 143,635,331 152,486,058 Non-Agency 142,019,587 53,485,053 Multi-Family 116,499,851 Total mortgage-backed securities $ 491,584,595 $ 368,315,738 The following tables present the amortized cost and fair value of the Company’s AFS investment securities by collateral type as of June 30, 2015 and December 31, 2014: June 30, 2015 Agency Non-Agency (1) Multi-Family Total Face Value $ 229,830,135 $ 188,029,097 $ 153,521,523 $ 571,380,755 Unamortized premium 1,202,379 66,825 - 1,269,204 Unamortized discount Designated credit reserve - (18,305,657 ) (2) - (18,305,657 ) Net, unamortized (1,887,043 ) (35,090,000 ) (36,154,385 ) (73,131,428 ) Amortized Cost 229,145,471 134,700,265 117,367,138 481,212,874 Gross unrealized gain 4,276,386 5,143,175 1,203,761 10,623,322 Gross unrealized (loss) (356,700 ) (1,424,572 ) (2,071,048 ) (3,852,320 ) Fair Value $ 233,065,157 $ 138,418,868 116,499,851 $ 487,983,876 December 31, 2014 Agency Non-Agency Total Face Value $ 309,790,551 $ 76,672,548 $ 386,463,099 Unamortized premium 4,796,106 - 4,796,106 Unamortized discount Designated credit reserve - (12,697,796 ) (12,697,796 ) Net, unamortized (2,244,687 ) (15,209,335 ) (17,454,022 ) Amortized Cost 312,341,970 48,765,417 361,107,387 Gross unrealized gain 3,670,643 4,732,247 8,402,890 Gross unrealized (loss) (1,181,928 ) (12,611 ) (1,194,539 ) Fair Value $ 314,830,685 $ 53,485,053 $ 368,315,738 (1) Non-Agency AFS does not include interest-only securities with a notional amount of $229,787,057, book value of $3,832,990, unrealized loss of $232,273 and a fair value of $3,600,718. (2) Discount designated as Credit Reserve and amount related to OTTI are generally not expected to be accreted into interest income. Amounts disclosed at June 30, 2015 reflect Credit Reserve of $1,410,284 and OTTI of $2,890,939. At June 30, 2015, the Company did not intend to sell any of its MBS that were in an unrealized loss position, and it is “more likely than not” that the Company will not be required to sell these MBS before recovery of their amortized cost basis, which may be at their maturity. The Company recognized credit-related OTTI losses through earnings of $167,784 on two Non-Agency RMBS and decreased credit reserves by $734,989 on two Non-Agency RMBS sold during the three months ended on June 30, 2015. Non-Agency RMBS on which OTTI is recognized have experienced, or are expected to experience, credit-related adverse cash flow changes, or credit impairment. The Company’s estimate of cash flows for its Non-Agency RMBS is based on its review of the underlying mortgage loans securing these RMBS. The Company considers information available about the structure of the securitization, including structural credit enhancement, if any, and the past and expected future performance of underlying mortgage loans, including timing of expected future cash flows, prepayment rates, default rates, loss severities, delinquency rates, percentage of non-performing loans, FICO scores at loan origination, year of origination, loan-to-value ratios, geographic concentrations, as well as Rating Agency reports, general market assessments, and dialogue with market participants. Significant judgment is used in both the Company’s analysis of the expected cash flows for its Non-Agency RMBS and any determination of OTTI that is the result, at least in part, of credit impairment. The following table presents the composition of OTTI charges recorded by the Company for the three and six months ended June 30, 2015 and 2014: Three Months Ended Three Months Ended June 30, 2015 June 30, 2014 (Increase)/decrease in credit reserves $ 567,205 $ - Additional other-than-temporary credit impairment losses - - Total impairment losses recognized in earnings 567,205 - Six Months Ended Six Months Ended June 30, 2015 June 30, 2014 ( Increase)/decrease in credit reserves (1,410,284 ) - Additional other-than-temporary credit impairment losses (2,890,939 ) - Total impairment losses recognized in earnings (4,301,223 ) - Unrealized losses on the Company’s Non-Agency RMBS were $1.4 million at June 30, 2015. Based upon the most recent evaluation, the Company does not consider these unrealized losses to be indicative of OTTI and does not believe that these unrealized losses to be credit related, but are rather due to non-credit factors, including changes in the rate of prepayments. To the extent the Company determines there are likely to be decreases in cash flows expected to be collected, and these are the result of non-credit impairment, such changes are generally recognized prospectively through adjustment of the loan’s yield over its remaining life. The following table presents a summary of the Company’s net realized gain (loss) from the sale of AFS securities, inclusive of securities previously booked as linked, for the three and six months ended June 30, 2015 and June 30, 2014: Three Months Ended Three Months Ended June 30, 2015 June 30, 2014 AFS securities sold, at cost $ 106,968,002 $ 11,997,363 Proceeds from AFS securities sold 107,609,266 12,915,101 Net realized gain (loss) on sale of AFS securities $ 641,264 $ 917,738 Six Months Ended Six Months Ended June 30, 2015 June 30, 2014 AFS securities sold, at cost $ 106,968,002 $ 106,746,157 Proceeds from AFS securities sold 107,609,266 103,535,140 Net realized gain (loss) on sale of AFS securities $ 641,264 $ (3,211,017 ) The following tables present the fair value of AFS investment securities by rate type as of June 30, 2015 and December 31, 2014: June 30, 2015 Agency Non-Agency Multi-Family Total Adjustable rate $ 216,373,089 $ 142,019,587 - $ 358,392,676 Fixed rate 16,692,069 - 116,499,851 133,191,920 Total $ 233,065,158 $ 142,019,587 116,499,851 $ 491,584,596 December 31, 2014 Agency Non-Agency Total Adjustable rate $ 229,648,342 $ 53,485,053 $ 283,133,395 Fixed rate 85,182,343 - 85,182,343 Total $ 314,830,685 $ 53,485,053 $ 368,315,738 The following tables present the fair value of AFS investment securities by maturity date as of June 30, 2015 and December 31, 2014: June 30, 2015 December 31, 2014 Less than one year $ - $ - Greater than one year and less than five years 62,111,743 35,855,146 Greater than or equal to five years 429,472,853 332,460,592 Total $ 491,584,596 $ 368,315,738 As described in Note 3, when the Company purchases a credit-sensitive AFS security at a significant discount to its face value, the Company generally does not amortize into income a significant portion of this discount that the Company is entitled to earn because it does not expect to collect it due to the inherent credit risk of the security. The Company may also record an OTTI for a portion of its investment in the security to the extent the Company believes that the amortized cost will exceed the present value of expected future cash flows. The amount of principal that the Company does not amortize into income is designated as an off balance sheet credit reserve on the security, with unamortized net discounts or premiums amortized into income over time to the extent realizable. Actual maturities of AFS securities are affected by the contractual lives of the associated mortgage collateral, periodic payments of principal, and prepayments of principal. Therefore actual maturities of available-for-sale securities are generally shorter than stated contractual maturities. Stated contractual maturities are generally greater than ten years. The following tables present the changes for the six months ended June 30, 2015 and year ended December 31, 2014 of the unamortized net discount and designated credit reserves on the Company’s MBS.
