Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Investment Objective | Organization and Investment Objective Ellington Financial Inc., formerly known as Ellington Financial LLC, was originally formed as a Delaware limited liability company on July 9, 2007 and commenced operations on August 17, 2007. On February 28, 2019, Ellington Financial LLC filed a certificate of conversion with the Secretary of State of the State of Delaware (the "Secretary") to convert from a Delaware limited liability company to a Delaware corporation (the "Conversion") and change its name to Ellington Financial Inc. The Conversion became effective on March 1, 2019, and upon effectiveness, each of Ellington Financial LLC's existing common shares representing limited liability company interests, no par value, converted into one issued and outstanding, fully paid and nonassessable share of common stock, $0.001 par value per share, of Ellington Financial Inc. In connection with the Conversion, Ellington Financial Inc.'s Board of Directors (the "Board of Directors") approved Ellington Financial Inc.'s Certificate of Incorporation (which was also filed with the Secretary) and Bylaws. Ellington Financial Operating Partnership LLC (the "Operating Partnership"), a 98.7% owned consolidated subsidiary of Ellington Financial Inc., was formed as a Delaware limited liability company on December 14, 2012 and commenced operations on January 1, 2013. All of Ellington Financial Inc.'s operations and business activities are conducted through the Operating Partnership. Ellington Financial Inc., the Operating Partnership, and their consolidated subsidiaries are hereafter collectively referred to as the "Company." All intercompany accounts are eliminated in consolidation. The Company conducts its operations to qualify and be taxed as a real estate investment trust, or "REIT," under the Internal Revenue Code of 1986, as amended (the "Code"), and has elected to be taxed as a corporation effective January 1, 2019. The Company has elected to be taxed as a REIT for U.S. federal income tax purposes. In anticipation of the Company's intended election to be taxed as a REIT under the Code beginning with its 2019 taxable year (the "REIT Election"), the Company implemented an internal restructuring as of December 31, 2018. As part of this restructuring, the Company moved certain of its non-REIT-qualifying investments and financial derivatives to taxable REIT subsidiaries or, "TRSs," and disposed of certain of its investments in non-REIT-qualifying investments and financial derivatives. The Company invests in a diverse array of financial assets, including residential and commercial mortgage loans, residential mortgage-backed securities, or "RMBS," commercial mortgage-backed securities, or "CMBS," consumer loans and asset-backed securities, or "ABS," including ABS backed by consumer loans, collateralized loan obligations, or "CLOs," non-mortgage- and mortgage-related derivatives, equity investments in loan origination companies, and other strategic investments. Ellington Financial Management LLC (the "Manager") is an SEC-registered investment adviser that serves as the Manager to the Company pursuant to the terms of its Seventh Amended and Restated Management Agreement (the "Management Agreement"), which was approved by the Board of Directors effective March 13, 2018. The Manager is an affiliate of Ellington Management Group, L.L.C. ("Ellington"), an investment management firm that is registered as both an investment adviser and a commodity pool operator. In accordance with the terms of the Management Agreement, the Manager implements the investment strategy and manages the business and operations on a day-to-day basis for the Company and performs certain services for the Company, subject to oversight by the Board of Directors. COVID-19 Impact During the first quarter of 2020, there was a worldwide outbreak of a novel coronavirus disease, or "COVID-19." The outbreak was declared a pandemic by the World Health Organization and numerous countries, including the United States, have responded by instituting quarantines or lockdowns, imposing restrictions on travel, restrictions on the ability of individuals to assemble in groups, and restrictions on the ability of certain businesses to operate, all of which have resulted in significant disruptions in the U.S. and global economies. In mid-March 2020, adverse economic conditions related to the COVID-19 pandemic began to impact the Company's financial position and results of operations. The COVID-19 pandemic has contributed to volatility, dislocations in the financial markets, and illiquidity. As a result, during the first quarter of 2020 the Company received margin calls under its repurchase agreements that were higher than typical historical levels. During the remainder of 2020, prices for most credit assets, which are assets for which the principal and interest payments are not guaranteed by a U.S. government agency or a U.S. government-sponsored entity, stabilized, and market volatility subsided, and as a result our margin calls reverted to more typical levels. We satisfied all margin calls during the year ended December 31, 2020. Actions by the U.S. Federal Reserve starting in the second half of March 2020 helped stabilize the market for certain assets, including RMBS for which the principal and interest payments are guaranteed by a U.S. government agency or a U.S. government-sponsored entity, or "Agency RMBS," and investment-grade corporate bonds, while other sectors, including non-investment-grade CMBS and CLOs, noticeably lagged. In light of the heightened levels of market volatility and systemic liquidity risk experienced during the first quarter of 2020, the Company proactively reduced the size of its Agency RMBS portfolio, thereby bolstering its liquidity and lowering its leverage, and it maintained a smaller Agency RMBS portfolio through the rest of 2020. Beginning in the second quarter, the Company resumed making new credit and Agency RMBS investments, but continued to maintain a higher cash balance and lower debt-to-equity ratio than prior to the outbreak of COVID-19. The Company's management team implemented business continuity plans, and the Company, the Manager, and Ellington continue to be fully operational in a largely work-from-home environment. Organization and Investment Objective Ellington Financial LLC was formed as a Delaware limited liability company on July 9, 2007 and commenced operations on August 17, 2007. Ellington Financial Operating Partnership LLC (the "Operating Partnership"), a 97.6% owned consolidated subsidiary of Ellington Financial LLC, was formed as a Delaware limited liability company on December 14, 2012 and commenced operations on January 1, 2013. All of the Company's operations and business activities are conducted through the Operating Partnership. Ellington Financial LLC, the Operating Partnership, and their consolidated subsidiaries are hereafter collectively referred to as the "Company." All intercompany accounts are eliminated in consolidation. The Company invests in a diverse array of financial assets, including residential mortgage-backed securities, or "RMBS," commercial mortgage-backed securities, or "CMBS," residential and commercial mortgage loans, consumer loans and asset-backed securities, or "ABS," backed by consumer loans, collateralized loan obligations, or "CLOs," non-mortgage and mortgage-related derivatives, equity investments in loan origination companies, and other strategic investments. Ellington Financial Management LLC ("EFM" or the "Manager") is an SEC-registered investment adviser and a registered commodity pool operator that serves as the Manager to the Company pursuant to the terms of its seventh amended and restated management agreement (the "Management Agreement").
