Investments, Debt and Equity Securities [Abstract] |
Residential Mortgage Securities and MSR-Related Assets | Residential Mortgage Securities and MSR-Related Assets 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”), which have interest rates that reset annually or more frequently (collectively, “ARM-MBS”); and (iii) 15 and 30 year fixed-rate mortgages for Agency MBS and, for Non-Agency MBS, 30-year and longer-term fixed rate mortgages. In addition, the Company’s MBS are also comprised of MBS backed by securitized 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. The Company’s RPL/NPL MBS are generally structured with a contractual coupon step-up feature where the coupon increases from 300 - 400 basis points at 36 - 48 months from issuance or sooner. The Company pledges a significant portion of its MBS as collateral against its borrowings under repurchase agreements and Swaps. (See Note 7) 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: The Company’s Non-Agency MBS are primarily 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 or sponsored by Fannie Mae and Freddie Mac. The payments of principal and interest on the CRT securities are paid by Fannie Mae or Freddie Mac, as the case may be, on a monthly basis, and are dependent on the performance of loans in either a reference pool or an actual pool of loans. As the loans in the underlying pool are paid, the principal balance of the CRT securities is paid. As an investor in a CRT security, the Company may incur a principal loss if the performance of the actual or reference pool loans results in either an actual or calculated loss that exceeds the credit enhancement of the security owned by the Company. The Company assesses the credit risk associated with CRT securities by assessing the current and expected future performance of the associated loan pool. The Company pledges a portion of its CRT securities as collateral against its borrowings under repurchase agreements.

(1) | Based on management’s current estimates of future principal cash flows expected to be received.
(2) | Amounts disclosed at September 30, 2019 include CRT securities with a fair value of $32.2 million for which the fair value option has been elected. Such securities had unrealized losses of $241,000 at September 30, 2019.
At September 30, 2019, 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. Gross unrealized losses on the Company’s Agency MBS were $19.3 million at September 30, 2019. 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 September 30, 2019 any unrealized losses on its Agency MBS were temporary. Gross unrealized losses on the Company’s Non-Agency MBS were $261,000 at September 30, 2019. 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 marketplace 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 did no t recognize any credit-related OTTI losses through earnings related to its Non-Agency MBS during the three and nine months ended September 30, 2019 and 2018. 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, year of origination, LTVs, geographic concentrations, 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 relative to the Company’s assumptions 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 a roll-forward of the credit loss component of OTTI on the Company’s Non-Agency MBS for which a non-credit component of OTTI was previously recognized in OCI. Changes in the credit loss component of OTTI are presented based upon whether the current period is the first time OTTI was recorded on a security or a subsequent OTTI charge was recorded.

MSR-Related Assets (a) Term Notes Backed by MSR-Related Collateral At September 30, 2019 and December 31, 2018, the Company had $1.1 billion and $538.5 million, respectively, of term notes issued by SPVs that have acquired rights to receive cash flows representing the servicing fees and/or excess servicing spread associated with certain MSRs. Payment of principal and interest on these term notes is considered to be largely dependent on cash flows generated by the underlying MSRs, as this impacts the cash flows available to the SPV that issued the term notes. At September 30, 2019, these term notes had an amortized cost of $1.1 billion, gross unrealized gains of approximately $5.4 million, a weighted average yield of 4.99% and a weighted average term to maturity of 5.7 years. At December 31, 2018, the term notes had an amortized cost of $538.5 million, gross unrealized losses of $7,000, a weighted average yield of 5.32% and a weighted average term to maturity of 4.7 years. (b) Corporate Loans The Company has made or participated in loans to provide financing to entities that originate residential mortgage loans and own the related MSRs. These corporate loans are secured by MSRs, as well as certain other unencumbered assets owned by the borrower. During the year ended December 31, 2018, the Company participated in a loan where the Company committed to lend $100.0 million of which approximately $60.2 million was drawn at September 30, 2019. At September 30, 2019, the coupon paid by the borrower on the drawn amount is 5.39%, the remaining term associated with the loan is 11 months and the remaining commitment period on any undrawn amount is 11 months. During the remaining commitment period, the Company receives a commitment fee between 0.25% and 1.0% based on the undrawn amount of the loan. In December 2016, the Company entered into a loan agreement under the terms of which it had committed to lend $130.0 million, of which approximately $124.2 million was drawn at March 31, 2018. This loan was paid in full during the three months ended June 30, 2018, at which time any remaining commitment was extinguished.
