MBS and CRT Securities

Agency and Non-Agency MBS

The Company’s MBS are comprised of Agency MBS and Non-Agency MBS which include MBS issued prior to 2008 (“Legacy Non-Agency MBS”) . These MBS are secured by: (i) hybrid mortgages (“Hybrids”), which have interest rates that are fixed for a specified period of time and, thereafter, generally adjust annually to an increment over a specified interest rate index; (ii) adjustable-rate mortgages (“ARMs”); (iii) mortgages that have interest rates that reset more frequently (collectively, “ARM-MBS”); and (iv) 15 year and longer-term fixed rate mortgages. In addition, the Company’s MBS are also comprised of MBS secured by re-performing/non-performing loans (“RPL/NPL MBS”), where the cash flows of the bond may not reflect the contractual cash flows of the underlying collateral. RPL/NPL MBS contain a feature where the coupon steps-up 300 basis points at 36 months from issuance or sooner.

The Company pledges a significant portion of its MBS as collateral against its borrowings under repurchase agreements, FHLB advances and Swaps. Non-Agency MBS that were accounted for as components of Linked Transactions prior to 2015 are not reflected in the tables for prior periods set forth in this note, as they were accounted for as derivatives. New accounting guidance that was effective for the Company on January 1, 2015 prospectively eliminated the use of Linked Transaction accounting. (See Notes 2(t), 6 and 9)

Agency MBS: Agency MBS are guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as Ginnie Mae. The payment of principal and/or interest on Ginnie Mae MBS is explicitly backed by the full faith and credit of the U.S. Government. Since the third quarter of 2008, Fannie Mae and Freddie Mac have been under the conservatorship of the Federal Housing Finance Agency, which significantly strengthened the backing for these government-sponsored entities.

Non-Agency MBS (including Non-Agency MBS transferred to consolidated VIEs): The Company’s Non-Agency MBS are secured by pools of residential mortgages, which are not guaranteed by an agency of the U.S. Government or any federally chartered corporation. Credit risk associated with Non-Agency MBS is regularly assessed as new information regarding the underlying collateral becomes available and based on updated estimates of cash flows generated by the underlying collateral.

CRT Securities

CRT securities are debt obligations issued by Fannie Mae and Freddie Mac. While the coupon payments are paid by Fannie Mae or Freddie Mac on a monthly basis, the payment of principal is dependent on the performance of loans in a reference pool of MBS securitized by Fannie Mae or Freddie Mac. As principal on loans in the reference pool are paid, principal payments on the securities are made and the principal balances of the securities are reduced. Consequently, CRT securities mirror the payment and prepayment behavior of the mortgage loans in the reference pool. As an investor in a CRT security, the Company may incur a loss if certain defined credit events occur, including if the loans in the reference pool experience delinquencies exceeding specified thresholds. The Company assesses the credit risk associated with CRT securities by assessing the current and expected future performance of the associated reference pool. CRT securities that were accounted for as components of Linked Transactions prior to 2015 are not reflected in the tables for prior periods set forth in this note, as they were accounted for as derivatives. (See Notes 2(t), 6 and 9)

(1) Based on management’s current estimates of future principal cash flows expected to be received.

(2) Amounts disclosed at December 31, 2015 includes CRT securities with a fair value of $54.1 million for which the fair value option has been elected. Such securities have unrealized losses of $555,000 at December 31, 2015.

At December 31, 2015, the Company did not intend to sell any of its investments that were in an unrealized loss position, and it is “more likely than not” that the Company will not be required to sell these securities before recovery of their amortized cost basis, which may be at their maturity. With respect to Non-Agency MBS held by consolidated VIEs, the ability of any entity to cause the sale to a third-party by the VIE prior to the maturity of these Non-Agency MBS is either specifically precluded, or is limited to specified events of default, none of which has occurred to date.

Gross unrealized losses on the Company’s Agency MBS were $40.4 million at December 31, 2015. Agency MBS are issued by Government Sponsored Entities (“GSEs”) and enjoy either the implicit or explicit backing of the full faith and credit of the U.S. Government. While the Company’s Agency MBS are not rated by any rating agency, they are currently perceived by market participants to be of high credit quality, with risk of default limited to the unlikely event that the U.S. Government would not continue to support the GSEs. Given the credit quality inherent in Agency MBS, the Company does not consider any of the current impairments on its Agency MBS to be credit related. In assessing whether it is more likely than not that it will be required to sell any impaired security before its anticipated recovery, which may be at its maturity, the Company considers for each impaired security, the significance of each investment, the amount of impairment, the projected future performance of such impaired securities, as well as the Company’s current and anticipated leverage capacity and liquidity position. Based on these analyses, the Company determined that at December 31, 2015 any unrealized losses on its Agency MBS were temporary.

Unrealized losses on the Company’s Non-Agency MBS (including Non-Agency MBS transferred to consolidated VIEs) were $28.4 million, of which $19.3 million were RPL/NPL MBS and $9.1 million were Legacy Non-Agency MBS at December 31, 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 are credit related, but are rather a reflection of current market yields and/or market place bid-ask spreads. The Company has reviewed its Non-Agency MBS that are in an unrealized loss position to identify those securities with losses that are other-than-temporary based on an assessment of changes in expected cash flows for such securities, which considers recent bond performance and, where possible, expected future performance of the underlying collateral.

The Company recognized credit-related OTTI losses through earnings related to its Non-Agency MBS of $705,000 during the year ended December 31, 2015. The Company did not recognize any credit-related OTTI losses through earnings related to its investments during the years ended December 31, 2014 and 2013.

Non-Agency MBS on which OTTI is recognized have experienced, or are expected to experience, credit-related adverse cash flow changes. The Company’s estimate of cash flows for these Non-Agency MBS is based on its review of the underlying mortgage loans securing these MBS. 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, LTVs, geographic concentrations, as well as Rating Agency reports, general market assessments, and dialogue with market participants. Changes in the Company’s evaluation of each of these factors impacts the cash flows expected to be collected at the OTTI assessment date. For Non-Agency MBS purchased at a discount to par that were assessed for and had no OTTI recorded this period, such cash flow estimates indicated that the amount of expected losses decreased compared to the previous OTTI assessment date. These positive cash flow changes are primarily driven by recent improvements in LTVs due to loan amortization and home price appreciation, which, in turn, positively impacts the Company’s estimates of default rates and loss severities for the underlying collateral. In addition, voluntary prepayments (i.e. loans that prepay in full with no loss) have generally trended higher for these MBS which also positively impacts the Company’s estimate of expected loss. Overall, the combination of higher voluntary prepayments and lower LTVs supports the Company’s assessment that such MBS are not other-than-temporarily impaired.

The following table presents the composition of OTTI charges recorded by the Company for the years ended December 31, 2015, 2014 and 2013:



	For the Year Ended December 31,
