NLY 2023 Annual Report

than not that it will be required to sell the security before recovery of its amortized cost basis, or (3) does not expect to recover the entire amortized cost basis of the security. Further, the security is analyzed for credit loss (the difference between the present value of cash flows expected to be collected and the amortized cost basis). The credit loss, if any, will then be recognized in the Consolidated Statements of Comprehensive Income (Loss) as a securities loss provision and reflected as an allowance for credit losses on securities on the Consolidated Statements of Financial Condition, while the balance of losses related to other factors will be recognized as a component of Other comprehensive income (loss). For the year ended December 31, 2021, the Company recognized a $0.4 million impairment on a commercial mortgage-backed security that it intended to sell. There was no impairment recognized for the years ended December 31, 2023 and 2022. When the fair value of a held-tomaturity security is less than the cost, the Company performs an analysis to determine whether it expects to recover the entire cost basis of the security. Agency Mortgage-Backed Securities - The Company invests in mortgage pass-through certificates, collateralized mortgage obligations and other MBS representing interests in or obligations backed by pools of residential or multifamily mortgage loans and certificates. Many of the underlying loans and certificates are guaranteed by the Government National Mortgage Association (“Ginnie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”) or the Federal National Mortgage Association (“Fannie Mae”) (collectively, “Agency mortgage-backed securities”). Agency mortgage-backed securities may include forward contracts for Agency mortgage-backed securities purchases or sales of a generic pool, on a to-be-announced basis. TBA securities without intent to accept delivery (“TBA derivatives”) are accounted for as derivatives as discussed in the “Derivative Instruments” Note. CRT Securities - CRT securities are risk sharing instruments issued by Fannie Mae and Freddie Mac, and similarly structured transactions arranged by third party market participants. CRT securities are designed to synthetically transfer mortgage credit risk from Fannie Mae and Freddie Mac to private investors. Non-Agency Mortgage-Backed Securities - The Company invests in non-Agency mortgage-backed securities such as those issued in prime loan, prime jumbo loan, Alt-A loan, subprime loan, non-performing loan (“NPL”) and re-performing loan (“RPL”) securitizations. Agency mortgage-backed securities, non-Agency mortgage-backed securities and residential CRT securities are referred to herein as “Residential Securities.” Although the Company generally intends to hold most of its Residential Securities until maturity, it may, from time to time, sell any of its Residential Securities as part of the overall management of its portfolio. Commercial Mortgage-Backed Securities (“Commercial Securities”) - The Company invests in Commercial Securities such as conduit, credit CMBS, single-asset single borrower and collateralized loan obligations.
