Note 4 — Investments in RMBS

RMBS on which the payment of principal and interest is guaranteed by a U.S. government agency or a U.S. government sponsored enterprise are referred to as “Agency RMBS.” RMBS also includes collateralized mortgage obligations (“CMOs”) which are either loss share securities issued by Fannie Mae or Freddie Mac or non-Agency RMBS, sometimes called “private label MBS,” which are structured debt instruments representing interests in specified pools of mortgage loans subdivided into multiple classes, or tranches, of securities, with each tranche having different maturities or risk profiles and different ratings by one or more nationally recognized statistical rating organizations (“NRSRO”). All of the Company’s RMBS are classified as available for sale and are, therefore, reported at fair value with changes in fair value recorded in other comprehensive income (loss) except for securities that are OTTI (dollars in thousands):

(A)	See Note 9 regarding the estimation of fair value, which approximates carrying value for all securities.
(B)	The Company used an implied AAA rating for the Agency RMBS. Collateralized mortgage obligations (“CMOs”) issued by Fannie Mae or Freddie Mac consist of loss share securities, approximately half of which, by unpaid principal balance (“UPB”), are unrated or rated below investment grade at December 31, 2019 by at least one NRSRO. Private label securities are rated investment grade or better by at least one NRSRO as of December 31, 2019.
(C)	The weighted average yield is based on the most recent gross monthly interest income, which is then annualized and divided by the book value of settled securities.
(D)	The weighted average maturity is based on the timing of expected principal reduction on the assets.

At December 31, 2019 and December 31, 2018, the Company pledged Agency RMBS with a carrying value of approximately $2,419.5 million and $1,698.7 million, respectively, as collateral for borrowings under repurchase agreements. At December 31, 2019 and December 31, 2018, the Company did not have any securities purchased from and financed with the same counterparty that did not meet the conditions of ASC 860, Transfers and Servicing , to be considered linked transactions and, therefore, classified as derivatives.

Based on management’s analysis of the Company’s securities, the performance of the underlying loans and changes in market factors, management determined that unrealized losses as of the balance sheet date on the Company’s securities were primarily the result of changes in market factors, rather than issuer-specific credit impairment, and such losses were considered temporary. The Company performed analyses in relation to such securities, using management’s best estimate of their cash flows, which support its belief that the carrying values of such securities were fully recoverable over their expected holding periods. Such market factors include changes in market interest rates and credit spreads and certain macroeconomic events, none of which will directly impact the Company’s ability to collect amounts contractually due. Management continually evaluates the credit status of each of the Company’s securities and the collateral supporting those securities. This evaluation includes a review of the credit of the issuer of the security (if applicable), the credit rating of the security (if applicable), the key terms of the security (including credit support), debt service coverage and loan to value ratios, the performance of the pool of underlying loans and the estimated value of the collateral supporting such loans, including the effect of local, industry and broader economic trends and factors. Significant judgment is required in this analysis. In connection with the above, the Company weighs the fact that a substantial majority of its investments in RMBS are guaranteed by U.S. government agencies or U.S. government sponsored enterprises.

Unrealized losses that are considered other than temporary are recognized in earnings. The Company did not record any OTTI charges during the year ended December 31, 2019 and recorded approximately $45,000 of OTTI charges during the year ended December 31, 2018.

The following tables summarize the Company’s securities in an unrealized loss position as of the dates indicated (dollars in thousands):

(A)	See Note 9 regarding the estimation of fair value, which approximates carrying value for all securities.
(B)	The Company used an implied AAA rating for the Agency RMBS. CMOs issued by Fannie Mae or Freddie Mac consist of loss share securities, approximately half of which, by UPB, are unrated or rated below investment grade at December 31, 2019 by at least one NRSRO. Private label securities are rated investment grade or better by at least one NRSRO as of December 31, 2019.
(C)	The weighted average yield is based on the most recent gross monthly interest income, which is then annualized and divided by the book value of settled securities.
(D)	The weighted average maturity is based on the timing of expected principal reduction on the assets. Except for the security for which the Company has recognized OTTI, the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases which may be maturity.
