(the “Company”) was incorporated in the Commonwealth of Virginia on December 18, 1987 and commenced operations in February 1988. The Company is an internally managed mortgage real estate investment trust, or mortgage REIT, which primarily earns income from investing on a leveraged basis in Agency mortgage-backed securities (“Agency MBS”) and in to-be-announced securities (“TBAs” or “TBA securities”). Agency MBS have a guaranty of principal and interest payments by a U.S. government-sponsored entity (“GSE”) such as Fannie Mae and Freddie Mac, which are in conservatorship and are currently supported by a senior preferred stock purchase agreement from the U.S. Treasury. As of December 31, 2023, the majority of the Company’s Agency MBS are secured by residential real property (“Agency RMBS”). The remainder of the Company’s investments are in Agency commercial MBS (“Agency CMBS”) and in both Agency and non-Agency CMBS interest-only (“CMBS IO”). Non-Agency MBS do not have a GSE guaranty of principal or interest payments.</span></div>
