The Company is managed by ACM, an investment advisor registered with the Securities and Exchange Commission ("SEC") (which registration the Company provides notice of to the state of Florida) (see Note 8 and Note 14 to the consolidated financial statements). We have elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). We believe that we are organized in conformity with the requirements for qualification as a REIT under the Code and our manner of operations enables us to meet the requirements for taxation as a REIT for federal income tax purposes (See Real Estate Investment Trust Requirements section below). All per share amounts, common shares outstanding and stock-based compensation amounts for all periods presented reflect our one-for-five reverse stock split (the "Reverse Stock Split"), which was effective September 29, 2023. No other reclassifications have been made to previously reported amounts. Strategies ARMOUR brings private capital into the mortgage markets to support home ownership for a broad and diverse spectrum of Americans. We seek to create stockholder value through thoughtful investment and risk management of a leveraged and diversified portfolio of MBS. We rely on the decades of experience of our management team for (i) MBS securities portfolio analysis and selection, (ii) access to equity capital and repurchase financing on potentially attractive rates and terms, and (iii) hedging and liquidity strategies to moderate interest rate and MBS price risk. We prioritize maintaining common share dividends appropriate for the intermediate term rather than focusing on short-term market fluctuations. We are deeply committed to implementing sustainable environmental, responsible social, and prudent governance practices that improve our work and our world. We strive to contribute to a healthy, sustainable environment by utilizing resources efficiently. As an organization, we create a relatively small environmental footprint. Still, we are focused on minimizing the environmental impact of our business where possible.

At December 31, 2024, we invested solely in MBS. Our investment in securities consists primarily of fixed rate loans. Our charter permits us to invest in MBS backed by fixed rate, hybrid adjustable rate and adjustable rate home loans as well as unsecured notes and bonds issued by GSEs, U.S. Treasuries and money market instruments. Borrowings We borrow against our MBS using repurchase agreements.
