Organization and Basis of Presentation

Note 1. Organization and Basis of Presentation

Arlington Asset Investment Corp. (“Arlington Asset”) and its consolidated subsidiaries (unless the context otherwise provides, collectively, the “Company”) is an investment firm that acquires and holds residential mortgage-related assets, primarily comprised of residential mortgage-backed securities (“MBS”). The Company’s investments in residential MBS include (i) residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”), government-sponsored enterprises (“GSEs”) or the Government National Mortgage Association (“Ginnie Mae”), a U.S. government agency, which are collectively referred to as “agency MBS,” and (ii) residential MBS issued by private institutions for which the principal and interest payments are not guaranteed by a GSE, which are referred to as “private-label MBS” or “non-agency MBS.”

The unaudited interim consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The Company’s unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

The Company’s consolidated financial statements include the accounts of Arlington Asset and all other entities in which the Company has a controlling financial interest. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Although the Company bases these estimates and assumptions on historical experience and all other reasonably available information that the Company believes to be relevant under the circumstances, such estimates frequently require management to exercise significant subjective judgment about matters that are inherently uncertain. Actual results may differ from these estimates materially.

Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the previously reported net income, other comprehensive income, total assets or total liabilities.
