MFA Financial Inc was incorporated in Maryland on July 24, 1997, and began operations on April 10, 1998. The Companys principal objective is to generate net income for stockholders resulting from the difference between the interest and other income earned from investments and the interest expense paid on leveraged investments and operating costs. The Company primarily invests in residential mortgage-backed securities that are issued or guaranteed by a federally chartered corporation or agency of the U.S. government such as Fannie Mae, Freddie Mac etc. and residential mortgage-backed securities that are not guaranteed by any U.S. government agency or any federally-chartered corporation. The mortgage-backed securities are primarily secured by pools of hybrid, adjustable-rate mortgage loans and 15-year fixed-rate mortgages. The Company has been elected to be treated as a REIT for U.S. federal income tax purposes. In order to maintain its qualification as a REIT, the Company must comply with a number of requirements under federal tax law, including that it must distribute at least 90% of its annual REIT taxable income to its stockholders.
