Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Maiden Holdings, Ltd. ("Parent Company" or "Maiden Holdings") and its subsidiaries (the "Company" or "Maiden"). They have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All significant intercompany transactions and accounts have been eliminated. These interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These unaudited Condensed Consolidated Financial Statements, including these notes, should be read in conjunction with the Company's audited Consolidated Financial Statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. Certain prior year comparatives have been reclassified to conform to the current year presentation. The effect of these reclassifications had no impact on previously reported shareholders' equity or net income. As a result of a series of strategic actions the Company has taken in recent years as discussed below, we create shareholder value by actively managing and allocating our assets and capital, including through ownership and management of businesses and assets mostly in the insurance and related financial services industries where we can leverage our deep knowledge of those markets. We also provide a full range of legacy services to small insurance companies, particularly those in run-off or with blocks of reserves that are no longer core, working with clients to develop and implement finality solutions including acquiring entire companies. We expect our legacy solutions business to contribute to our active asset and capital management strategies. Short-term income protection business is written on a primary basis by our wholly owned subsidiaries Maiden Life Försäkrings AB ("Maiden LF") and Maiden General Försäkrings AB ("Maiden GF") in the Scandinavian and Northern European markets. Insurance support services are provided to Maiden LF and Maiden GF by our services company, Maiden Global Holdings Ltd. (“Maiden Global”), which is also a licensed intermediary in the United Kingdom. Maiden Global had previously operated internationally by providing branded auto and credit life insurance products through insurer partners, particularly those in the European Union ("EU") and other global markets. These products also produced reinsurance programs which were underwritten by our wholly owned subsidiary Maiden Reinsurance Ltd. (“Maiden Reinsurance”). The Company is not actively underwriting reinsurance business but has some historic reinsurance programs underwritten by Maiden Reinsurance which are in run-off. The Company continues to run-off the liabilities associated with AmTrust Financial Services, Inc. ("AmTrust") reinsurance agreements which were terminated in 2019 as discussed in "Note 10 - Related Party Transactions". We have a retroactive reinsurance agreement and a commutation agreement that further reduces our exposure and limits the potential volatility related to these AmTrust liabilities, which are discussed in "Note 8 - Reinsurance". Since 2018, the Company has engaged in a series of strategic measures that have dramatically reduced the regulatory capital required to operate our business, materially strengthened our solvency ratios, re-domiciled Maiden Reinsurance from Bermuda to the State of Vermont in the U.S. and ceased active reinsurance underwriting. These transactions can be found in Part II of our Annual Report on Form 10-K for the year ended December 31, 2020 that was filed with the SEC on March 15, 2021 and are more fully described (as applicable) in "Note 8 - Reinsurance" and "Note 10 - Related Party Transactions" in these financial statements. Please see the Company's audited Consolidated Financial Statements, and related notes thereto, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 for further details on the above transactions. Re-domestication of Maiden Reinsurance Effective March 16, 2020, we re-domesticated our principal operating subsidiary, Maiden Reinsurance, from Bermuda to the State of Vermont in the U.S., having determined that re-domesticating Maiden Reinsurance to Vermont enables us to better align our capital and resources with our liabilities, which originate mostly in the U.S., resulting in a more efficient structure. Maiden Reinsurance is now subject to the statutes and regulations of Vermont in the ordinary course of business. The re-domestication, in combination with other strategic measures described above that were completed in 2019, will continue to strengthen the Company’s capital position and solvency ratios. While the Vermont Department of Financial Regulation ("Vermont DFR") is now the group supervisor for the Company, the re-domestication did not apply to the Parent Company which remains a Bermuda-based holding company. Securities issued by Maiden Holdings were not affected by the re-domestication of Maiden Reinsurance to Vermont. Concurrent with its re-domestication to Vermont on March 16, 2020, Maiden Holdings contributed as capital the remaining 65% of its ownership in Maiden Reinsurance to Maiden Holdings North America, Ltd. ("Maiden NA"). Maiden NA now owns 100% of Maiden Reinsurance in the aggregate. 1. Basis of Presentation (continued) COVID-19 Pandemic The continuing COVID-19 global pandemic has caused significant disruption to the economy and financial markets globally, and the full extent of the potential impacts of COVID-19 are not yet known. Circumstances caused by the COVID-19 pandemic are complex, uncertain and rapidly evolving. Our results of operations, financial condition, and liquidity and capital resources may have been adversely impacted by the COVID-19 pandemic, and the future impact of the pandemic on our financial condition or results of operations is difficult to predict. As described herein, the Company is not presently engaged in active reinsurance underwriting and is running off the remaining unearned exposures it has reinsured. The Company's Swedish and UK insurance operations ("IIS unit") do write limited primary insurance coverages that could be exposed to COVID-19 claims. While we assess our exposure to COVID-19 insurance and reinsurance claims on our existing insurance exposures and remaining reinsurance exposures as limited and immaterial, given the uncertainty surrounding the COVID-19 pandemic and its impact on the insurance industry, our preliminary estimates of loss and loss adjustment expenses ("loss and LAE") and estimates of reinsurance recoverable arising from the COVID-19 pandemic may materially change. Maiden Reinsurance has not received any COVID-19 claims to date but our companies within our IIS unit have received a limited number of claims related to those coverages which it deems as immaterial. Unanticipated issues relating to claims and coverage may emerge, which could adversely affect our business by increasing the scope of coverage beyond our intent and/or increasing the frequency and severity of claims. The Company's investment portfolio may be adversely impacted by unfavorable market conditions caused by the COVID-19 pandemic, and the Company and its reinsurance subsidiaries may need additional capital to maintain compliance with regulatory capital requirements and/or be required to post additional collateral under existing reinsurance arrangements, which could reduce our liquidity. In addition, the Company may experience continued volatility in its results of operations which could negatively impact its financial condition and create a reduction in the amount of available distribution or dividend capacity from its regulated reinsurance subsidiaries, which would also reduce liquidity.
