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 wholly owned subsidiary 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 our wholly-owned subsidiary 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.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies There have been no material changes to the significant accounting policies as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 except for the following: Recently Adopted Accounting Standards Updates No new accounting standards have been recently adopted for the nine months ended September 30, 2021. Recently Issued Accounting Standards Not Yet Adopted Accounting for Measurement of Credit Losses on Financial Instruments In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13 "Financial Instruments: Credit Losses (Topic 326)" replacing the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires financial assets to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 also modified the accounting for available-for-sale ("AFS") debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments: Credit Losses Available-for-Sale Debt Securities . Credit losses relating to AFS debt securities will be recorded through an allowance for credit losses rather than under the current other-than-temporarily impaired ("OTTI") methodology. In April 2019, the FASB issued ASU 2019-04 for targeted improvements related to ASU 2016-13 which clarify that an entity should include all expected recoveries in its estimate of the allowance for credit losses. In addition, for collateral dependent financial assets, the amendments mandate that an allowance for credit losses that is added to the amortized cost basis of the financial asset should not exceed amounts previously written off. It also clarifies FASB’s intent to include all reinsurance recoverables within the scope of Topic 944 to be within the scope of Subtopic 326-20 , regardless of the measurement basis of those recoverables. The Company's reinsurance recoverable on unpaid losses is currently the most significant financial asset within the scope of ASU 2016-13. The guidance is effective for public business entities, excluding entities eligible to be smaller reporting companies ("SRCs") as defined by the SEC, for annual periods beginning after December 15, 2019, and interim periods therein. The guidance is effective for all other entities, including public entities eligible to be SRCs, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. As of September 30, 2021, the Company qualified for SRC status, as determined on the last business day of its most recent second quarter, and is thus eligible to follow the reporting deadlines and effective dates applicable to SRCs. Therefore, Topic 326 will not be effective until fiscal year 2023. The Company continues to evaluate the impact of this guidance on its results of operations, financial condition and liquidity.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company currently has two reportable segments: Diversified Reinsurance and AmTrust Reinsurance. Our Diversified Reinsurance segment consists of a portfolio of predominantly property and casualty reinsurance business focusing on regional and specialty property and casualty insurance companies located primarily in Europe. Our AmTrust Reinsurance segment includes all business ceded to Maiden Reinsurance by AmTrust, primarily the quota share reinsurance agreement (“AmTrust Quota Share”) between Maiden Reinsurance and AmTrust’s wholly owned subsidiary, AmTrust International Insurance, Ltd. (“AII”) and the European hospital liability quota share reinsurance contract ("European Hospital Liability Quota Share") with AmTrust’s wholly owned subsidiaries, AmTrust Europe Limited ("AEL") and AmTrust International Underwriters DAC ("AIU DAC"), which are both in run-off effective January 1, 2019. Please refer to "Note 10. Related Party Transactions" for additional information regarding the AmTrust Reinsurance segment. The Company evaluates segment performance based on segment profit separately from the results of our investment portfolio. General and administrative expenses are allocated to the segments on an actual basis except salaries and benefits where management’s judgment is applied; however general corporate expenses are not allocated to the segments. In determining total assets by reportable segment, the Company identifies those assets that are attributable to a particular segment such as reinsurance balances receivable, reinsurance recoverable on unpaid losses, deferred commission and other acquisition expenses, funds withheld receivable, loan to related party and restricted cash and investments. All remaining assets are allocated to Corporate. The following tables summarize the underwriting results of our reportable segments and the reconciliation of our reportable segments' underwriting results to consolidated net income: For the Three Months Ended September 30, 2021 Diversified Reinsurance AmTrust Reinsurance Total Gross premiums written $ 5,684 $ 1,137 $ 6,821 Net premiums written $ 5,816 $ 1,137 $ 6,953 Net premiums earned $ 7,521 $ 7,509 $ 15,030 Other insurance revenue 138 — 138 Net loss and LAE (554) (9,960) (10,514) Commission and other acquisition expenses (3,461) (2,852) (6,313) General and administrative expenses (1,583) (407) (1,990) Underwriting income (loss) $ 2,061 $ (5,710) (3,649) Reconciliation to net loss Net investment income and net realized and unrealized losses on investment 6,540 Interest and amortization expenses (4,832) Foreign exchange and other gains, net 4,116 Other general and administrative expenses (4,660) Income tax benefit 155 Interest in loss of equity method investments (810) Net loss $ (3,140) Net loss and LAE ratio (1) 7.2 % 132.6 % 69.3 % Commission and other acquisition expense ratio (2) 45.2 % 38.0 % 41.6 % General and administrative expense ratio (3) 20.7 % 5.4 % 43.9 % Expense ratio (4) 65.9 % 43.4 % 85.5 % Combined ratio (5) 73.1 % 176.0 % 154.8 % 3.

Investments	Investments The Company holds: (i) AFS portfolios of fixed maturity and equity securities, carried at fair value; (ii) other investments, of which certain investments are carried at fair value and investments in direct lending entities are carried at cost less impairment; (iii) equity method investments; and (iv) funds held - directly managed. a) Fixed Maturities The amortized cost, gross unrealized gains and losses, and fair value of fixed maturities at September 30, 2021 and December 31, 2020 are as follows: September 30, 2021 Original or amortized cost Gross unrealized gains Gross unrealized losses Fair value U.S. treasury bonds $ 73,485 $ 16 $ (7) $ 73,494 U.S. agency bonds – mortgage-backed 117,205 3,915 (103) 121,017 Non-U.S. government bonds 3,164 187 — 3,351 Asset-backed securities 204,601 930 (2,693) 202,838 Corporate bonds 359,380 17,787 (5,440) 371,727 Total fixed maturity investments $ 757,835 $ 22,835 $ (8,243) $ 772,427 December 31, 2020 Original or amortized cost Gross unrealized gains Gross unrealized losses Fair value U.S. treasury bonds $ 94,468 $ 34 $ — $ 94,502 U.S. agency bonds – mortgage-backed 272,124 9,439 (126) 281,437 Non-U.S. government bonds 8,641 1,067 — 9,708 Asset-backed securities 184,227 1,611 (406) 185,432 Corporate bonds 604,463 40,904 (3,035) 642,332 Total fixed maturity investments $ 1,163,923 $ 53,055 $ (3,567) $ 1,213,411 The contractual maturities of our fixed maturities are shown below.

Investments (continued) At September 30, 2021, there were 55 securities in an unrealized loss position with a fair value of $214,960 and unrealized losses of $8,243. Of these securities, there were 14 securities that have been in an unrealized loss position for twelve months or greater with a fair value of $44,863 and unrealized losses of $3,349. Less than 12 Months 12 Months or More Total December 31, 2020 Fair Unrealized Fair Unrealized Fair Unrealized U.S. agency bonds – mortgage-backed $ 19,360 $ (85) $ 5,646 $ (41) $ 25,006 $ (126) Asset-backed securities 13,371 (217) 31,052 (189) 44,423 (406) Corporate bonds 31,839 (890) 65,296 (2,145) 97,135 (3,035) Total temporarily impaired fixed maturities $ 64,570 $ (1,192) $ 101,994 $ (2,375) $ 166,564 $ (3,567) At December 31, 2020, there were 53 securities in an unrealized loss position with a fair value of $166,564 and unrealized losses of $3,567. Of these securities, there were 35 securities that have been in an unrealized loss position for twelve months or greater with a fair value of $101,994 and unrealized losses of $2,375. Other-than-temporarily impaired The Company performs quarterly reviews of its fixed maturities in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance. At September 30, 2021, we determined that unrealized losses on fixed maturities were primarily due to changes in interest rates as well as the impact of foreign exchange rate changes on certain foreign currency denominated fixed maturities since their date of purchase. All fixed maturity securities continue to pay the expected coupon payments under the contractual terms of the securities. Any credit-related impairment related to fixed maturity securities that the Company does not plan to sell and for which we are not more likely than not to be required to sell is recognized in net earnings, with the non-credit related impairment recognized in comprehensive earnings. Based on analysis, our fixed maturity portfolio is of high credit quality and we believe the amortized cost basis of the securities will ultimately be recovered. The Company continually monitors the credit quality of the fixed maturity investments to assess if it is probable that it will receive contractual or estimated cash flows in the form of principal and interest. For the three and nine months ended September 30, 2020, the Company recognized $962 and $2,468 in OTTI charges in earnings on two and four fixed maturity securities, respectively. There was no impairment recorded for the three and nine months ended September 30, 2021, respectively.

Investments (continued) b) Other Investments and Equity Method Investments Certain of the Company's other investments and equity method investments are subject to restrictions on redemptions and sales that are determined by the governing documents, which could limit our ability to liquidate those investments. These restrictions may include lock-ups, redemption gates, restricted share classes, restrictions on the frequency of redemption and notice periods. A gate is the ability to deny or delay a redemption request. Certain other investments and equity method investments may not have any restrictions governing their sale, but there is no active market and no guarantee that we will be able to execute a sale in a timely manner. In addition, even if certain other investments and equity method investments are not eligible for redemption or sales are restricted, the Company may still receive income distributions from those investments. Other investments The table shows the composition of the Company's other investments as at September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Carrying value % of Total Carrying value % of Total Other privately held investments $ 44,351 42.7 % $ 26,094 38.9 % Private credit funds 15,149 14.6 % 1,301 1.9 % Private equity funds 4,643 4.4 % 3,044 4.6 % Total other investments at fair value 64,143 61.7 % 30,439 45.4 % Investments in direct lending entities (at cost) 39,745 38.3 % 36,571 54.6 % Total other investments $ 103,888 100.0 % $ 67,010 100.0 % The Company's investments in direct lending entities of $39,745 at September 30, 2021 (December 31, 2020 - $36,571) are carried at cost less impairment, if any, with any indication of impairment recognized in income when determined. Please see "Note 5(d) - Fair Value Measurements" for additional information regarding this investment.

The table below shows the carrying value of the Company's equity method investments at September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Carrying Value % of Total Carrying Value % of Total Hedge fund investments $ 31,221 41.6 % $ 29,435 73.8 % Real estate investments 42,551 56.7 % — — % Other investments 1,278 1.7 % 10,451 26.2 % Total equity method investments $ 75,050 100.0 % $ 39,886 100.0 % The equity method investments above include limited partnerships which are variable interests issued by variable interest entities ("VIEs"). The Company does not have the power to direct the activities that are most significant to the economic performance of these VIEs therefore the Company is not the primary beneficiary of these VIEs. T he Company is deemed to have limited influence over the operating and financial policies of the investee and accordingly these investments are reported under the equity method of accounting. In applying the equity method of accounting, the investments are initially recorded at cost and are subsequently adjusted based on the Company’s proportionate share of the investee's net income or loss. 4. Investments (continued) Generally, the maximum exposure to loss on these interests is limited to the amount of commitment made by the Company.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments (a) Fair Values of Financial Instruments Fair Value Measurements — Accounting Standards Codification Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820") defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. Additionally, ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of inputs: • Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Examples of assets and liabilities utilizing Level 1 inputs include: U.S. Treasury bonds; • Level 2 — Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) or can be corroborated by observable market data. Examples of assets and liabilities utilizing Level 2 inputs include: U.S. government-sponsored agency securities; non-U.S. government and supranational obligations; commercial mortgage-backed securities ("CMBS"); collateralized loan obligations ("CLO"); corporate and municipal bonds; and • Level 3 — Valuations based on models where significant inputs are not observable. The unobservable inputs reflect our own assumptions about assumptions that market participants would use developed on the basis of the best information available in the particular circumstances. Examples of assets and liabilities utilizing Level 3 inputs include: an investment in preference shares of a start-up insurance producer. The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument, whether the financial instrument is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires significantly more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in the Level 3 hierarchy. The Company uses prices and inputs that are current as at the measurement date. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified between hierarchy levels. For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these in the Level 1 hierarchy. The Company receives the quoted market prices from a third party nationally recognized provider ("the Pricing Service"). When quoted market prices are unavailable, the Company utilizes the Pricing Service to determine an estimate of fair value. The fair value estimates are included in the Level 2 hierarchy. The Company will challenge any prices for its investments which are considered not to be representative of fair value. If quoted market prices and an estimate from the Pricing Service are unavailable, the Company produces an estimate of fair value based on dealer quotations for recent activity in positions with the same or similar characteristics to that being valued. The Company determines whether the fair value estimate is in the Level 2 or Level 3 hierarchy depending on the level of observable inputs available when estimating the fair value. The Company bases its estimates of fair values for assets on the bid price as it represents what a third party market participant would be willing to pay in an orderly transaction. ASC 825, "Disclosure About Fair Value of Financial Instruments" , requires all entities to disclose the fair value of their financial instruments for assets and liabilities recognized and not recognized in the balance sheet, for which it is practicable to estimate fair value. The following describes the valuation techniques used by the Company to determine the fair value of financial instruments that are measured at fair value on a recurring basis held at September 30, 2021 and December 31, 2020. U.S. government and U.S. agency — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, Federal National Mortgage Association and the Federal Farm Credit Banks Funding Corporation. The fair values of U.S. treasury bonds are based on quoted market prices in active markets, and are included in the Level 1 fair value hierarchy. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. agency bonds are included in the Level 2 fair value hierarchy. Non-U.S. government and supranational bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government and supranational bonds are observable market inputs, the fair values of non-U.S. government and supranational bonds are included in the Level 2 fair value hierarchy. 5. Fair Value Measurements (continued) Asset-backed securities — These securities comprise commercial mortgage-backed securities ("CMBS") and collateralized loan obligations ("CLO") originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS and CLO are observable market inputs, their fair values are included in the Level 2 fair value hierarchy. Corporate and municipal bonds — Bonds issued by corporations, U.S. state and municipality entities or agencies that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The credit spreads are sourced from broker/dealers, trade prices and new issue market. Where pricing is unavailable from pricing services, custodian pricing or non-binding quotes are obtained from broker-dealers to estimate fair values. As significant inputs used to price corporate and municipal bonds are observable market inputs, fair values are included in the Level 2 fair value hierarchy. Equity securities - The fair value of equity securities is primarily priced by pricing services, reflecting the closing price quoted for the final trading day of the period. The common stock is carried at fair value using observable market pricing data and is included in the Level 1 fair value hierarchy. Any unrealized gains or losses on the investment is recorded in net income in the period in which they occur. Other investments — Includes unquoted investments comprised of the following investments: • Privately held investments: These are direct equity investments in common and preferred stock of privately held entities. The fair values are estimated using quarterly financial statements and/or recent private market transactions and thus included under Level 3 of the fair value hierarchy due to unobservable market data used for valuation. These investments are also comprised of investments in insurtech and other insurance focused companies. The fair value of these start-up insurance entities are determined using recent private market transactions where applicable and included in the Level 3 fair value hierarchy due to unobservable market data used for valuation. • Private credit funds: These are privately held equity investments in common stock of entities that lend money valued using the most recently available or quarterly net asset value ("NAV") statements as provided by the external fund manager or third-party administrator and therefore measured using the NAV as a practical expedient. • Private equity funds: These are comprised of private equity funds, private equity co-investments with sponsoring entities and investments in real estate limited partnerships and joint ventures . The fair value is estimated based on the most recently available NAV as advised by the external fund manager or third-party administrator. The fair values are therefore measured using the NAV as a practical expedient. 5. Fair Value of Financial Instruments (continued) (b) Fair Value Hierarchy The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in ASC 820. The framework is based on the inputs used in valuation and gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuation methodology whenever available. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active trading markets and the lowest priority to unobservable inputs that reflect significant market assumptions. At September 30, 2021 and December 31, 2020, the Company classified financial instruments measured at fair value on a recurring basis in the following valuation hierarchy: September 30, 2021 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value Based on NAV Practical Expedient Total Fair Value Fixed maturities U.S. treasury bonds $ 73,494 $ — $ — $ — $ 73,494 U.S. agency bonds – mortgage-backed — 121,017 — — 121,017 Non-U.S. government bonds — 3,351 — — 3,351 Asset-backed securities — 202,838 — — 202,838 Corporate bonds — 371,727 — — 371,727 Equity investments 1,903 — — — 1,903 Other investments — — 29,344 34,799 64,143 Total $ 75,397 $ 698,933 $ 29,344 $ 34,799 $ 838,473 As a percentage of total assets 3.1 % 28.5 % 1.2 % 1.4 % 34.2 % December 31, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value Based on NAV Practical Expedient Total Fair Value Fixed maturities U.S. treasury bonds $ 94,502 $ — $ — $ — $ 94,502 U.S. agency bonds – mortgage-backed — 281,437 — — 281,437 Non-U.S. government bonds — 9,708 — — 9,708 Asset-backed securities — 185,432 — — 185,432 Corporate bonds — 642,332 — — 642,332 Other investments — — 26,094 4,345 30,439 Total $ 94,502 $ 1,118,909 $ 26,094 $ 4,345 $ 1,243,850 As a percentage of total assets 3.2 % 37.9 % 0.9 % 0.1 % 42.1 % The Company utilizes the Pricing Service to assist in determining the fair value of its investments; however, management is ultimately responsible for all fair values presented in the Company’s financial statements. This includes responsibility for monitoring the fair value process, ensuring objective and reliable valuation practices, and pricing of assets and liabilities and use of pricing sources. The Company analyzes and reviews the information and prices received from the Pricing Service to ensure that the prices provided represent a reasonable estimate of fair value. The Pricing Service was utilized to estimate fair value measurements for 99.2% and 99.1% of our fixed maturities at September 30, 2021 and December 31, 2020, respectively. The Pricing Service utilizes market quotations for fixed maturity securities that have quoted market prices in active markets. Since fixed maturities other than U.S. treasury bonds generally do not trade actively on a daily basis, the Pricing Service prepares estimates of fair value measurements using relevant market data, benchmark curves, sector groupings and matrix pricing and these have been classified as Level 2 within the fair value hierarchy. At September 30, 2021 and December 31, 2020, approximately 0.8% and 0.9%, respectively, of our fixed maturities were valued using the market approach. At September 30, 2021, one security or $6,444 (2020 - two securities or $10,809) of fixed maturities classified as Level 2 were priced using a quotation from a broker and/or custodian as opposed to the Pricing Service due to lack of information available. At September 30, 2021 and December 31, 2020, the Company has not adjusted any pricing provided to it based on the review performed by its investment managers. 5. Fair Value of Financial Instruments (continued) During the nine months ended September 30, 2021, the Company transferred its equity investment in an insurtech start-up company focused on technological advancement in the automobile insurance industry out of Level 3 within the fair value hierarchy and into Level 1 due to the recent completion of its initial public offering. There were no transfers to or from Level 3 during the nine months ended September 30, 2020. (c) Level 3 Financial Instruments At September 30, 2021, the Company holds Level 3 financial instruments of $29,344 (December 31, 2020 - $26,094) which includes privately held equity investments in common stock and preferred stock. The fair value of these investments are estimated using quarterly unaudited financial statements or recent private market transactions, where applicable. Due to significant unobservable inputs in these valuations, the Company classifies their fair values as Level 3 within the fair value hierarchy. The following table provides a summary of quantitative information regarding the significant unobservable inputs used in determining the fair value of other investments measured at fair value on a recurring basis under the Level 3 classification at September 30, 2021: Fair Value Valuation Technique Unobservable Inputs Range Other privately held investments $ 27,544 Quarterly financial statements Estimated maturity dates 1.0 years to 3.0 years Other privately held investments 1,800 Recent market transactions Liquidity discount rates Total Level 3 investments $ 29,344 The following table shows the reconciliation of the beginning and ending balances for other investments measured at fair value on a recurring basis using Level 3 inputs for the three and nine months ended September 30, 2021 and 2020. The Company includes any related interest and dividend income in net investment income and thus are excluded from the reconciliation in the table below: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2021 2020 2021 2020 Balance - beginning of period $ 29,344 $ 2,800 $ 26,094 $ 1,800 Purchases — — 4,250 1,000 Transfers out of Level 3 — — (1,000) — Total Level 3 investments - end of period $ 29,344 $ 2,800 $ 29,344 $ 2,800 (d) Financial Instruments Disclosed, But Not Carried, at Fair Value The fair value of financial instruments accounting guidance also applies to financial instruments disclosed, but not carried, at fair value, except for certain financial instruments related to insurance contracts . At September 30, 2021, the carrying values of cash and cash equivalents (including restricted amounts), accrued investment income, reinsurance balances receivable, loan to related party, liability for securities purchased and certain other assets and liabilities approximate fair values due to their inherent short duration. As these financial instruments are not actively traded, their fair values are classified as Level 2. The investments made by direct lending entities are carried at cost less impairment, if any, which approximates fair value. The fair value estimates of these investments are not based on observable market data and, as a result, are classified as Level 3. The fair values of the Senior Notes (as defined in "Note 7 - Long-Term Debt" ) are based on indicative market pricing obtained from a third-party pricing service which uses observable market inputs, and therefore the fair values of these liabilities are classified as Level 2. The following table presents the respective carrying value and fair value for the Senior Notes as at September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Carrying Value Fair Value Carrying Value Fair Value Senior Notes - MHLA – 6.625% $ 110,000 $ 97,680 $ 110,000 $ 90,772 Senior Notes - MHNC – 7.75% 152,500 149,267 152,500 132,126 Total Senior Notes $ 262,500 $ 246,947 $ 262,500 $ 222,898

Reinsurance Disclosures [Abstract]
Reinsurance	Reinsurance The Company uses reinsurance and retrocessional agreements ("ceded reinsurance") to mitigate volatility, reduce its exposure to certain risks and provide capital support. Ceded reinsurance provides for the recovery of a portion of loss and LAE under certain circumstances without relieving the Company of its obligations to the policyholders. The Company remains liable to the extent that any of its reinsurers or retrocessionaires fails to meet their obligations. Loss and LAE incurred and premiums earned are reported after deduction for ceded reinsurance. In the event that one or more of our reinsurers or retrocessionaires are unable to meet their obligations under these agreements, the Company would not realize the full value of the reinsurance recoverable balances. The effect of ceded reinsurance on net premiums written and earned and on net loss and LAE for the nine months ended September 30, 2021 and 2020 was as follows: For the Nine Months Ended September 30, 2021 2020 Premiums written Direct $ 16,181 $ 14,718 Assumed (8,316) 5,515 Ceded (347) (2,740) Net $ 7,518 $ 17,493 Premiums earned Direct $ 17,186 $ 14,630 Assumed 24,103 64,853 Ceded (1,183) (2,655) Net $ 40,106 $ 76,828 Loss and LAE Gross loss and LAE $ 6,132 $ 54,845 Loss and LAE ceded 1,414 (13,686) Net $ 7,546 $ 41,159 The Company's reinsurance recoverable on unpaid losses balance as at September 30, 2021 was $561,627 (December 31, 2020 - $592,571) presented in the Condensed Consolidated Balance Sheets. At September 30, 2021 and December 31, 2020, the Company had no valuation allowance against reinsurance recoverable on unpaid losses. On December 27, 2018, Cavello Bay Reinsurance Limited ("Cavello") and Maiden Reinsurance entered into a retrocession agreement pursuant to which certain assets and liabilities associated with the U.S. treaty reinsurance business held by Maiden Reinsurance were 100.0% retroceded to Cavello in exchange for a ceding commission. The reinsurance recoverable on unpaid losses due from Cavello under this retrocession agreement was $62,813 at September 30, 2021 (December 31, 2020 - $67,972). On July 31, 2019, Maiden Reinsurance and Cavello entered into a Loss Portfolio Transfer and Adverse Development Cover Agreement (the "LPT/ADC Agreement") pursuant to which Cavello assumed the loss reserves as of December 31, 2018 associated with the AmTrust Quota Share in excess of a $2,178,535 retention up to $600,000, in exchange for a retrocession premium of $445,000. The $2,178,535 retention is subject to adjustment for paid losses subsequent to December 31, 2018. The LPT/ADC Agreement provides Maiden Reinsurance with $155,000 in adverse development cover over its carried AmTrust Quota Share loss reserves at December 31, 2018. The LPT/ADC Agreement meets the criteria for risk transfer and is thus accounted for as retroactive reinsurance. Cumulative ceded losses exceeding $445,000 are recognized as a deferred gain liability and amortized into income over the settlement period of the ceded reserves in proportion to cumulative losses collected over the estimated ultimate reinsurance recoverable. The amount of the deferral is recalculated each period based on loss payments and updated estimates. Consequently, cumulative adverse development subsequent to December 31, 2018 may result in significant losses from operations until periods when the deferred gain is recognized as a benefit to earnings. As of September 30, 2021, the reinsurance recoverable on unpaid losses under the retroactive reinsurance agreement was $495,645 while the deferred gain liability was $50,645 (December 31, 2020 - $519,941 and $74,941, respectively). Amortization of the deferred gain will not occur until paid losses have exceeded the minimum retention under the LPT/ADC Agreement, which is estimated to be in 2024. Cavello provided collateral in the form of a letter of credit in the amount of $445,000 to AmTrust under the LPT/ADC Agreement. Cavello is subject to additional collateral funding requirements as explained in "Note 10. Related Party Transactions". As of September 30, 2021, the amount of collateral required was $403,627. Under the terms of the LPT/ADC Agreement, the covered losses associated with the Commutation and Release Agreement with AmTrust are eligible to be covered but recoverable only when such losses are paid or settled by AII or its affiliates, provided such losses and other related amounts shall not exceed $312,786. Cavello's parent company, Enstar, has credit ratings of BBB from both Standard & Poor's and Fitch Ratings at September 30, 2021.

Reserve for Loss and Loss Adjus

Reserve for Loss and Loss Adjustment Expenses	9 Months Ended

Insurance [Abstract]
Reserve for Loss and Loss Adjustment Expenses	Reserve for Loss and Loss Adjustment Expenses The Company uses both historical experience and industry-wide loss development factors to provide a reasonable basis for estimating future losses. In the future, certain events may be beyond the control of management, such as changes in law, judicial interpretations of law, and rates of inflation, which may favorably or unfavorably impact the ultimate settlement of the Company’s loss and LAE reserves. The anticipated effect of inflation is implicitly considered when estimating liabilities for loss and LAE. While anticipated changes in claim costs due to inflation are considered in estimating the ultimate claim costs, changes in the average severity of claims are caused by a number of factors that vary with the individual type of policy written. Ultimate losses are projected based on historical trends adjusted for implemented changes in underwriting standards, claims handling, policy provisions, and general economic trends. Those anticipated trends are monitored based on actual development and are modified if necessary. The reserving process begins with the collection and analysis of paid losses and incurred claims data for each of the Company's contracts. While reserves are mostly reviewed on a contract by contract basis, paid loss and incurred claims data is also aggregated into reserving segments. The segmental data is disaggregated by reserving class and further disaggregated by either accident year (i.e. the year in which the loss event occurred) or by underwriting year (i.e. the year in which the contract generating the premium and losses incepted). In cases where the Company uses underwriting year information, reserves are subsequently allocated to the respective accident year. The reserve for loss and LAE consists of: September 30, 2021 December 31, 2020 Reserve for reported loss and LAE $ 864,935 $ 998,691 Reserve for losses incurred but not reported ("IBNR") 702,591 894,608 Reserve for loss and LAE $ 1,567,526 $ 1,893,299 The following table represents a reconciliation of our beginning and ending gross and net loss and LAE reserves: For the Nine Months Ended September 30, 2021 2020 Gross loss and LAE reserves, January 1 $ 1,893,299 $ 2,439,907 Less: reinsurance recoverable on unpaid losses, January 1 592,571 623,422 Net loss and LAE reserves, January 1 1,300,728 1,816,485 Net incurred losses related to: Current year 31,259 48,988 Prior years (23,713) (7,829) 7,546 41,159 Net paid losses related to: Current year (17,137) (5,253) Prior years (288,202) (519,864) (305,339) (525,117) Retroactive reinsurance adjustment 24,296 32,955 Effect of foreign exchange rate movements (21,332) 11,914 Net loss and LAE reserves, September 30 1,005,899 1,377,396 Reinsurance recoverable on unpaid losses, September 30 561,627 597,677 Gross loss and LAE reserves, September 30 $ 1,567,526 $ 1,975,073 Prior period development arises from changes to loss estimates recognized in the current year that relate to loss reserves established in previous calendar years. The favorable or unfavorable development reflects changes in management's best estimate of the ultimate losses under the relevant reinsurance policies after considerable review of changes in actuarial assessments. During the three and nine months ended September 30, 2021, the Company recognized net favorable prior year loss development of $5,352 and $23,713, respectively (2020 - favorable $7,236 and $7,829, respectively). In the Diversified Reinsurance segment, net favorable prior year loss development was $1,676 and $2,613, respectively, for the three and nine months ended September 30, 2021 (2020 - adverse $483 and $312, respectively). Prior year loss development for the three and nine months ended September 30, 2021 was due to favorable reserve development in German Auto Programs, European Capital Solutions and other runoff business. The adverse prior year loss development for the three and nine months ended September 30, 2020 was primarily due to adverse reserve development in European Capital Solutions. In the AmTrust Reinsurance segment, the net favorable prior year loss development was $3,676 and $21,100, respectively, for the three and nine months ended September 30, 2021 (2020 - favorable $7,719 and $8,141, respectively). The net favorable prior year loss development for the three and nine months ended September 30, 2021 was primarily due to favorable prior year Note 9. Reserve for Loss and Loss Adjustment Expenses (continued) development in Workers Compensation and Commercial Auto Liability partly offset by adverse development in Hospital Liability. The net favorable prior year loss development for the three and nine months ended September 30, 2020 was primarily due to favorable development in Workers Compensation partly offset by adverse development within Commercial Auto and General Liability programs. Retroactive reinsurance adjustment of $24,296 represents the decrease in reinsurance recoverable on unpaid losses under the LPT/ADC Agreement with Cavello that was recognized in the nine months ended September 30, 2021 (2020 - $32,955) in the reconciliation of our beginning and ending gross and net loss and LAE reserves presented above. It reflects the corresponding decrease in the deferred gain on retroactive reinsurance for favorable development on reserves covered under the LPT/ADC Agreement of $24,296 during the nine months ended September 30, 2021 (2020 - $9,250). This adjustment also includes the Workers Compensation commuted losses of $23,705 during the nine months ended September 30, 2020. The deferred gain on retroactive reinsurance represents the cumulative adverse development under the AmTrust Quota Share covered under the LPT/ADC Agreement at September 30, 2021 and December 31, 2020. Amortization of the deferred gain will not occur until paid losses have exceeded the minimum retention under the LPT/ADC Agreement, which is estimated to be in 2024.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Founding Shareholders of the Company were Michael Karfunkel, George Karfunkel and Barry Zyskind. Based on each individual's most recent public filing, Leah Karfunkel (wife of the late Michael Karfunkel) owns or controls approximately 7.8% of the Company's outstanding common shares and Barry Zyskind (the Company's non-executive chairman) owns or controls approximately 7.3% of the Company's outstanding common shares. George Karfunkel owns or controls less than 5.0% of the Company's outstanding common shares. Leah Karfunkel and George Karfunkel are directors of AmTrust, and Barry Zyskind is the chief executive officer and chairman of AmTrust. Leah Karfunkel, George Karfunkel and Barry Zyskind own or control approximately 53.2% of the ownership interests of Evergreen Parent LP, the ultimate parent of AmTrust. The following describes transactions that have transpired between the Company and AmTrust: AmTrust Quota Share Effective July 1, 2007, the Company and AmTrust entered into a master agreement, as amended ("Master Agreement"), by which they caused Maiden Reinsurance and AII to enter into the AmTrust Quota Share by which AII retroceded to Maiden Reinsurance an amount equal to 40% of the premium written by subsidiaries of AmTrust, net of the cost of unaffiliated inuring reinsurance and 40% of losses. The Master Agreement further provided that AII receive a ceding commission of 31% of ceded written premiums. On June 11, 2008, Maiden Reinsurance and AII amended the AmTrust Quota Share to add Retail Commercial Package Business to the Covered Business (as defined in the AmTrust Quota Share). AII receives a ceding commission of 34.375% on Retail Commercial Package Business. On July 1, 2016, the agreement was renewed through June 30, 2019. Effective July 1, 2018, the amount AEL ceded to Maiden Reinsurance was reduced to 20%. Effective July 1, 2013, for the Specialty Program portion of Covered Business only, AII was responsible for ultimate net loss otherwise recoverable from Maiden Reinsurance to the extent that the loss ratio to Maiden Reinsurance, which shall be determined on an inception to date basis from July 1, 2007 through the date of calculation, is between 81.5% and 95% ("Loss Corridor"). Above and below the Loss Corridor, Maiden Reinsurance continued to reinsure losses at its proportional 40% share of the AmTrust Quota Share. Effective July 31, 2019, the Loss Corridor was amended such that the maximum amount covered is $40,500, the amount calculated by Maiden Reinsurance for the Loss Corridor coverage as of March 31, 2019. Any development above this maximum amount will be subject to the coverage of the LPT/ADC Agreement. Effective January 1, 2019, Maiden Reinsurance and AII entered into a partial termination amendment ("Partial Termination Amendment") which amended the AmTrust Quota Share. The Partial Termination Amendment provided for the cut-off of the ongoing and unearned premium of AmTrust’s Small Commercial Business, comprising workers’ compensation, general liability, umbrella liability, professional liability (including cyber liability) insurance coverages, and U.S. Specialty Risk and Extended Warranty ("Terminated Business") as of December 31, 2018. Under the Partial Termination Amendment, the ceding commission payable by Maiden Reinsurance for its remaining in-force business immediately prior to January 1, 2019 increased by five percentage points with respect to in-force remaining business (excluding Terminated Business) and related unearned premium as of January 1, 2019. The Partial Termination Amendment resulted in Maiden Reinsurance returning $647,980 in unearned premium to AII, or $436,760 net of applicable ceding commission and brokerage as calculated during the second quarter of 2019. Subsequently, on January 30, 2019, Maiden Reinsurance and AII agreed to terminate the remaining business subject to the AmTrust Quota Share on a run-off basis effective as of January 1, 2019. Effective July 31, 2019, Maiden Reinsurance and AII entered into a Commutation and Release Agreement which provided for AII to assume all reserves ceded by AII to Maiden Reinsurance with respect to its proportional 40% share of the ultimate net loss under the AmTrust Quota Share related to the commuted business including: (a) all losses incurred in Accident Year 2017 and Accident Year 2018 under California workers' compensation policies and as defined in the AmTrust Quota Share ("Commuted California Business"); and (b) all losses incurred in Accident Year 2018 under New York workers' compensation policies ("Commuted New York Business"), and together with the Commuted California Business ("Commuted Business") in exchange for the release and full discharge of Maiden Reinsurance's obligations to AII with respect to the Commuted Business. The Commuted Business excludes any business classified by AII as Specialty Program or Specialty Risk business. 10. Related Party Transactions (continued) Maiden Reinsurance paid $312,786 ("Commutation Payment"), which is the sum of the net ceded reserves in the amount of $330,682 with respect to the Commuted Business as of December 31, 2018 less payments in the amount of $17,896 made by Maiden Reinsurance with respect to the Commuted Business from January 1, 2019 through July 31, 2019. The Commutation Payment was settled on August 12, 2019 and Maiden Reinsurance paid AII approximately $6,335 in interest related to the Commutation Payment premium, calculated at the rate of 3.30% per annum from January 1, 2019 through August 12, 2019. AII and Maiden Reinsurance also agreed that as of July 31, 2019, the AmTrust Quota Share was deemed amended as applicable so that the Commuted Business is no longer included as part of Covered Business under the AmTrust Quota Share. On January 30, 2019, in connection with the termination of the reinsurance agreement described above, the Company and AmTrust entered into a second amendment to the Master Agreement between the parties, originally entered into on July 3, 2007, to remove the provisions requiring AmTrust to reinsure business with the Company. European Hospital Liability Quota Share Effective April 1, 2011, Maiden Reinsurance entered into the European Hospital Liability Quota Share with AEL and AIU DAC. Pursuant to the terms of the European Hospital Liability Quota Share, Maiden Reinsurance assumed 40% of the premiums and losses related to policies classified as European Hospital Liability, including associated liability coverages and policies covering physician defense costs, written or renewed on or after April 1, 2011. The European Hospital Liability Quota Share also covers policies written or renewed on or before March 31, 2011, but only with respect to losses that occur, accrue or arise on or after April 1, 2011. The maximum limit of liability attaching shall be €5,000 (€10,000 effective January 1, 2012) or currency equivalent (on a 100% basis) per original claim for any one original policy. Maiden Reinsurance paid a ceding commission of 5% on contracts assumed under the European Hospital Liability Quota Share. Effective July 1, 2016, the European Hospital Liability Quota Share was amended such that Maiden Reinsurance assumes from AEL 32.5% of the premiums and losses of all policies written or renewed on or after July 1, 2016 until June 30, 2017 and 20% of all policies written or renewed on or after July 1, 2017. Thereafter, on January 30, 2019, Maiden Reinsurance, AEL and AIU DAC agreed to terminate the European Hospital Liability Quota Share on a run-off basis effective as of January 1, 2019. The table below shows the effect of both of these quota share arrangements with AmTrust on the Company's Condensed Consolidated Income Statements for the three and nine months ended September 30, 2021 and 2020, respectively: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2021 2020 2021 2020 Gross and net premiums written $ 1,137 $ (5,635) $ (3,082) $ (10,340) Net premiums earned 7,509 12,981 19,383 41,205 Net loss and LAE (9,960) (2,441) (4,330) (21,456) Commission and other acquisition expenses (2,852) (5,447) (7,486) (16,221) Collateral provided to AmTrust a) AmTrust Quota Share To provide AmTrust's U.S. insurance subsidiaries with credit for reinsurance on their statutory financial statements, AII, as the direct reinsurer of AmTrust's insurance subsidiaries, established trust accounts ("Trust Accounts") for their benefit. Maiden Reinsurance has provided appropriate collateral to secure its proportional share under the AmTrust Quota Share of AII's obligations to the AmTrust subsidiaries to whom AII is required to provide collateral which can include (a) assets loaned by Maiden Reinsurance to AII for deposit into the Trust Accounts, pursuant to a loan agreement between those parties, (b) assets transferred by Maiden Reinsurance for deposit into the Trust Accounts, or (c) a letter of credit obtained by Maiden Reinsurance and delivered to an AmTrust subsidiary on AII's behalf. Maiden Reinsurance may provide any or a combination of these forms of collateral, provided that the aggregate value thereof equals Maiden Reinsurance's proportionate share of its obligations under the AmTrust Quota Share. Maiden Reinsurance satisfied its collateral requirements under the AmTrust Quota Share with AII as follows: • by lending funds of $167,975 at September 30, 2021 and December 31, 2020 pursuant to a loan agreement entered into between those parties. Advances under the loan are secured by promissory notes. This loan was assigned by AII to AmTrust effective December 31, 2014 and is carried at cost. Interest is payable at a rate equivalent to the Federal Funds Effective Rate ("Fed Funds") plus 200 basis points per annum. Interest income on the loan was $885 and $2,611 for the three and nine months ended September 30, 2021, respectively (2020 - $886 and $3,111, respectively) and the effective yield was 2.1% and 2.1% for the same respective periods (2020 - 2.1% and 2.5%, respectively). • on January 30, 2019, in connection with the termination of the reinsurance agreements described above, the Company and AmTrust amended the Loan Agreement between Maiden Reinsurance, AmTrust and AII, originally entered into on November 16, 2007, by extending the maturity date to January 1, 2025 and specifies that due to the termination of the AmTrust Quota Share, no further loans or advances may be made pursuant to the Loan Agreement; 10. Related Party Transactions (continued) • effective December 1, 2008, the Company entered into a Reinsurer Trust Assets Collateral agreement to provide to AII sufficient collateral to secure its proportional share of AII's obligations to the U.S. AmTrust subsidiaries. The amount of the collateral at September 30, 2021 was $328,891 (December 31, 2020 - $666,879) and the accrued interest was $1,893 (December 31, 2020 - $3,048). Please refer to "Note 4. (e) Investments" for additional information; • on January 11, 2019, a portion of the existing Trust Accounts used for collateral on the AmTrust Quota Share were converted to a funds withheld arrangement. The Company transferred $575,000 to AmTrust as a funds withheld receivable which currently has an annual interest rate of 1.8%, subject to annual adjustment. The annual interest rate was 2.65% for the duration of 2020. At September 30, 2021, the funds withheld balance was $575,000 (December 31, 2020 - $575,000) and the accrued interest was $2,609 (December 31, 2020 - $3,845). The interest income on the funds withheld receivable was $2,609 and $7,741 for the three and nine months ended September 30, 2021, respectively (2020 - $3,845 and $11,451, respectively). Pursuant to the terms of the LPT/ADC Agreement, Maiden Reinsurance, Cavello and AmTrust and certain of its affiliated companies entered into a Master Collateral Agreement (“MCA”) to define and enable the operation of collateral provided under the AmTrust Quota Share. Under the MCA, Cavello provided letters of credit on behalf of Maiden Reinsurance to AmTrust in an amount representing Cavello’s obligations under the LPT/ADC Agreement. Because these letters of credit replaced other collateral previously provided directly by Maiden Reinsurance to AmTrust, the MCA coordinates the collateral protection that will be provided to AmTrust to ensure that no gaps in collateral funding occur by operation of the LPT/ADC Agreement and related MCA. As a result of entering into both the LPT/ADC Agreement and the MCA, certain post-termination endorsements (“PTEs”) to the AmTrust Quota Share between AII and Maiden Reinsurance were required. Effective July 31, 2019, the PTEs: i) enable the operation of both the LPT/ADC Agreement and MCA by making provision for certain forms of collateral, including letters of credit provided by Cavello on Maiden Reinsurance’s behalf, and further defines the permitted use and return of collateral; and ii) increase the required funding percentage for Maiden Reinsurance under the collateral arrangements between the parties to 105% of its obligations, subject to a minimum excess funding requirement of $54,000, as may be mutually amended by the parties from time to time. Under certain defined conditions, Maiden Reinsurance may be required to increase this funding percentage to 110%. Effective March 16, 2020, Maiden Reinsurance discontinued as a Bermuda company and completed its re-domestication to the State of Vermont. Bermuda is a Solvency II equivalent jurisdiction and the State of Vermont is not such a jurisdiction; therefore, the collateral provided under the respective agreements with AmTrust subsidiaries was strengthened to reflect the impact of the re-domestication concurrent with the date of Maiden Reinsurance’s re-domestication to Vermont. Maiden Reinsurance and AmTrust agreed to: 1) amend the AmTrust Quota Share pursuant to Post Termination Endorsement No. 2 effective March 16, 2020; and 2) amend the European Hospital Liability Quota Share pursuant to Post Termination Endorsement No. 1 effective March 16, 2020. Pursuant to the terms of Post Termination Endorsement No. 2 to the AmTrust Quota Share, Maiden Reinsurance strengthened the collateral protection provided by Maiden Reinsurance to AII by increasing the required funding percentage for Maiden Reinsurance under the collateral arrangements between the parties to 110% of its obligations, subject to a minimum excess funding requirement of $54,000, as may be mutually amended by the parties from time to time. Post Termination Endorsement No. 2 also sets forth conditions by which the funding percentage will be reduced and the sequence of how collateral will be utilized as obligations, as defined under the AmTrust Quota Share, are satisfied. Pursuant to the terms of Post Termination Endorsement No. 1 to the European Hospital Liability Quota Share, Maiden Reinsurance strengthened the collateral protection provided by Maiden Reinsurance to AEL and AIU DAC by increasing the required funding percentage for Maiden Reinsurance under the collateral arrangements between the parties to the greater of 120% of the Exposure (as defined therein) and the amount of security required to offset the increase in the Solvency Capital Requirement (“SCR”) that results from the changes in the SCR which arise out of Maiden Reinsurance's re-domestication as compared to the SCR calculation if Maiden Reinsurance had remained domesticated in a Solvency II equivalent jurisdiction with a solvency ratio above 100% and provided collateral equivalent to 100% of the Exposure. b) European Hospital Liability Quota Share Collateral has been provided to both AEL and AIU DAC under the European Hospital Liability Quota Share. For AEL, the amount of the collateral held in reinsurance trust accounts at September 30, 2021 was $286,118 (December 31, 2020 - $318,063) and the accrued interest was $1,577 (December 31, 2020 - $2,283). For AIU DAC, the Company utilizes funds withheld to satisfy its collateral requirements. At September 30, 2021, the amount of funds withheld was $28,734 (December 31, 2020 - $28,093) and the accrued interest was $107 (December 31, 2020 - $318). AIU DAC pays Maiden Reinsurance a fixed annual interest rate of 0.5% on the average daily funds withheld balance which is subject to annual adjustment. The interest income on the funds withheld receivable was $37 and $111 for the three and nine months ended September 30, 2021, respectively (2020 - $64 and $262, respectively). 10. Related Party Transactions (continued) Brokerage Agreement Effective July 1, 2007, the Company entered into a reinsurance brokerage agreement with AII Reinsurance Broker Ltd.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees There are no material changes from the commitments, contingencies and concentrations previously disclosed in the Company’s Form 10-K for the year ended December 31, 2020 except for the guarantees related to the indebtedness of others as disclosed in Note 11 (b) below. a) Concentrations of Credit Risk At September 30, 2021 and December 31, 2020, the Company’s assets where significant concentrations of credit risk may exist include investments, cash and cash equivalents, loan to related party, reinsurance recoverable on unpaid losses and funds withheld receivable. Please refer to " Note 8. Reinsurance " for additional information regarding the Company's credit risk exposure on its reinsurance counterparties including the impact of the LPT/ADC Agreement effective January 1, 2019. The Company requires its reinsurers to have adequate financial strength. The Company evaluates the financial condition of its reinsurers and monitors its concentration of credit risk on an ongoing basis. Provisions are made for amounts considered potentially uncollectible. Letters of credit are provided by its reinsurers for material amounts recoverable as discussed in " Note 8. Reinsurance ". The Company manages the concentration of credit risk in its investment portfolio through issuer and sector exposure limitations. The Company believes it bears minimal credit risk in its cash on deposit. The Company also monitors the credit risk related to the loan to related party and funds withheld receivable, within which the largest balances are due from AmTrust. AmTrust has a financial strength/credit rating of A- (Excellent) from A.M. Best at September 30, 2021. To mitigate credit risk, the Company generally has a contractual right of offset thereby allowing claims to be settled net of any premiums or loan receivable. The Company believes these balances as at September 30, 2021 will be fully collectible. b) Investment Commitments and Related Financial Guarantees The Company had unfunded commitments on other investments of $101,431 at September 30, 2021 (2020 - $63,313). Please refer to "Note 4 (b) - Investments" for details on unfunded commitments for other investments held at September 30, 2021. The remaining unfunded commitments on other investments at September 30, 2021 includes commitments for a private credit fund investment and a private equity fund investment for which the Company had agreements to fund at September 30, 2021. The Company had unfunded commitments on equity method investments of $26,949 at September 30, 2021. Certain of the Company's investments in limited partnerships are related to real estate joint ventures with interests in multi-property projects with varying strategies ranging from the development of properties to the ownership of income-producing properties. In certain of these joint ventures, the Company has provided certain indemnities, guarantees and commitments to certain parties such that it may be required to make payments now or in the future. Any loss for which the Company could be liable would be contingent on the default of a loan by the real estate joint venture entity for which the Company provided a financial guarantee to a lender. While the Company has committed to aggregate limits as to the amount of guarantees it will provide as part of its limited partnerships, guarantees are only provided on an individual transaction basis and are subject to the terms and conditions of each transaction mutually agreed by the parties involved. The Company is not bound to such guarantees without its express authorization. As discussed above, at September 30, 2021, guarantees of $33,191 have been provided to lenders by the Company on behalf of real estate joint ventures, however, the likelihood of the Company incurring any losses pertaining to project level financing guarantees was determined to be remote. Therefore, no liability has been accrued under ASC 450-20. c) Operating Lease Commitments The Company leases office spaces, housing, office equipment and company vehicles under various operating leases expiring in various years through 2024. The Company terminated one of its office leasing arrangements and its subleasing arrangement during the nine months ended September 30, 2021. The Company's leases are currently classified as operating leases and none of them have non-lease components. For operating leases that have an initial lease term of more than twelve months, and whose lease payments are above a certain threshold, the Company recognizes a lease liability and a right-of-use asset in the Condensed Consolidated Balance Sheets at the present value of the remaining lease payments until expiration. As the lease contracts generally do not provide an implicit discount rate, the Company used the weighted-average discount rate of 10%, representing its secured incremental borrowing rate, in calculating the present value of the lease liability. This amount is recorded as a lease liability within accrued expenses and other liabilities with an equivalent amount for the right-of-use asset presented as part of other assets and is deemed insignificant at September 30, 2021. The Company's weighted-average remaining lease term is approximately 2.7 years at September 30, 2021. d) Legal Proceedings Except as noted below, the Company is not a party to any material legal proceedings. From time to time, the Company is subject to routine legal proceedings, including arbitration, arising in the ordinary course of business. These legal proceedings generally relate to claims asserted by or against the Company in the ordinary course of insurance or reinsurance operations. Based on the Company's opinion, the eventual outcome of these legal proceedings is not expected to have a material adverse effect on its financial condition or results of operations. In April 2009, the Company learned that Bentzion S. Turin, the former Chief Operating Officer, General Counsel and Secretary of Maiden Holdings and Maiden Reinsurance, sent a letter to the U.S. Department of Labor claiming that his employment with the Company was terminated in retaliation for corporate whistle-blowing in violation of the whistle-blower protection provisions of the Sarbanes-Oxley Act of 2002. Mr. Turin alleged that he was terminated for raising concerns 11. Commitments, Contingencies and Guarantees (continued) regarding corporate governance with respect to the negotiation of the terms of the Trust Preferred Securities Offering. He seeks reinstatement as Chief Operating Officer, General Counsel and Secretary of Maiden Holdings and Maiden Reinsurance, back pay and legal fees incurred. On December 31, 2009, the U.S. Secretary of Labor found no reasonable cause for Mr. Turin’s claim and dismissed the complaint in its entirety. Mr. Turin objected to the Secretary's findings and requested a hearing before an administrative law judge in the U.S. Department of Labor. The Company moved to dismiss Mr. Turin's complaint, and its motion was granted by the Administrative Law Judge on June 30, 2011. On July 13, 2011, Mr. Turin filed a petition for review of the Administrative Law Judge's decision with the Administrative Review Board in the U.S. Department of Labor. On March 29, 2013, the Administrative Review Board reversed the dismissal of the complaint on procedural grounds, and remanded the case to the administrative law judge. The administrative hearing began in September 2014 and concluded in November 2018. On September 2, 2021, Administrative Law Judge Theresa C. Timlin of the U.S. Department of Labor issued a decision and order which denied Mr. Turin’s complaint in full. On September 16, 2021, Mr. Turin filed a petition for review of the Administrative Law Judge's decision with the Administrative Review Board in the U.S. Department of Labor. The Company believes that it had good and sufficient reasons for terminating Mr. Turin's employment and that the claim is without merit. The Company will continue to vigorously defend itself against this claim. A putative class action complaint was filed against Maiden Holdings, Arturo M. Raschbaum, Karen L. Schmitt, and John M. Marshaleck in the United States District Court for the District of New Jersey on February 11, 2019. On February 19, 2020, the Court appointed lead plaintiffs, and on May 1, 2020, lead plaintiffs filed an amended class action complaint (the “Amended Complaint”).The Amended Complaint asserts violations of Section 10(b) of the Exchange Act and Rule 10b-5 (and Section 20(a) for control person liability) arising in large part from allegations that Maiden failed to take adequate loss reserves in connection with reinsurance provided to AmTrust. Plaintiffs further claim that certain of Maiden Holdings’ representations concerning its business, underwriting and financial statements were rendered false by the allegedly inadequate loss reserves, that these misrepresentations inflated the price of Maiden Holdings' common stock, and that when the truth about the misrepresentations was revealed, the Company’s stock price fell, causing Plaintiffs to incur losses. On September 11, 2020, a motion to dismiss was filed on behalf of all Defendants. On August 6, 2021, the Court issued an order denying, in part, Defendants’ motion to dismiss, ordering Plaintiffs to file a shorter amended complaint no later than August 20, 2021, and permitting discovery to proceed on a limited basis. We believe the claims are without merit and we intend to vigorously defend ourselves. It is possible that additional lawsuits will be filed against the Company, its subsidiaries and its respective officers due to the diminution in value of our securities as a result of our operating results and financial condition. It is currently uncertain as to the effect of such litigation on our business, operating results and financial condition.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company uses the estimated annual effective tax rate method. Certain items, including those deemed to be unusual, infrequent or that cannot be reliably estimated, are excluded from the estimated annual effective tax rate. In these cases, the actual tax expense or benefit is reported in the same period as the related item. Certain tax effects are also not reflected in the estimated annual effective tax rate, primarily certain changes in the realizability of deferred tax assets "(DTAs") and uncertain tax positions. Maiden NA files a consolidated federal income tax return for the Company’s U.S. based subsidiaries, including Maiden Reinsurance, which re-domesticated from Bermuda to Vermont on March 16, 2020 and, as a result, became subject to U.S. taxes. Maiden NA has net operating loss carry-forwards and other DTAs and deferred tax liabilities that are not presently recognized as a net DTA because a full valuation allowance is currently carried against them. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief and Economic Security Act (the “CARES” Act) to mitigate the economic impacts of COVID-19. The Company believes that the provisions of the CARES Act will not have a material impact on its U.S. federal tax liabilities.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In September 2021, the Company authorized the open market repurchase of its outstanding preference shares in accordance with a written plan adopted pursuant to Rule 10b5-1 of the Securities Exchange Act of 1934. The Company intends to finance these repurchases using its available unrestricted cash.

Accounting Policies [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 wholly owned subsidiary 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"
Recently Adopted Accounting Standards Updates and Recently Issued Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards Updates No new accounting standards have been recently adopted for the nine months ended September 30, 2021. Recently Issued Accounting Standards Not Yet Adopted Accounting for Measurement of Credit Losses on Financial Instruments In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13 "Financial Instruments: Credit Losses (Topic 326)" replacing the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires financial assets to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 also modified the accounting for available-for-sale ("AFS") debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments: Credit Losses Available-for-Sale Debt Securities . Credit losses relating to AFS debt securities will be recorded through an allowance for credit losses rather than under the current other-than-temporarily impaired ("OTTI") methodology. In April 2019, the FASB issued ASU 2019-04 for targeted improvements related to ASU 2016-13 which clarify that an entity should include all expected recoveries in its estimate of the allowance for credit losses. In addition, for collateral dependent financial assets, the amendments mandate that an allowance for credit losses that is added to the amortized cost basis of the financial asset should not exceed amounts previously written off. It also clarifies FASB’s intent to include all reinsurance recoverables within the scope of Topic 944 to be within the scope of Subtopic 326-20 , regardless of the measurement basis of those recoverables. The Company's reinsurance recoverable on unpaid losses is currently the most significant financial asset within the scope of ASU 2016-13. The guidance is effective for public business entities, excluding entities eligible to be smaller reporting companies ("SRCs") as defined by the SEC, for annual periods beginning after December 15, 2019, and interim periods therein. The guidance is effective for all other entities, including public entities eligible to be SRCs, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. As of September 30, 2021, the Company qualified for SRC status, as determined on the last business day of its most recent second quarter, and is thus eligible to follow the reporting deadlines and effective dates applicable to SRCs. Therefore, Topic 326 will not be effective until fiscal year 2023. The Company continues to evaluate the impact of this guidance on its results of operations, financial condition and liquidity.
Fair Value of Financial Instruments	Fair Values of Financial Instruments Fair Value Measurements — Accounting Standards Codification Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820") defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. Additionally, ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of inputs: • Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Examples of assets and liabilities utilizing Level 1 inputs include: U.S. Treasury bonds; • Level 2 — Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) or can be corroborated by observable market data. Examples of assets and liabilities utilizing Level 2 inputs include: U.S. government-sponsored agency securities; non-U.S. government and supranational obligations; commercial mortgage-backed securities ("CMBS"); collateralized loan obligations ("CLO"); corporate and municipal bonds; and • Level 3 — Valuations based on models where significant inputs are not observable. The unobservable inputs reflect our own assumptions about assumptions that market participants would use developed on the basis of the best information available in the particular circumstances. Examples of assets and liabilities utilizing Level 3 inputs include: an investment in preference shares of a start-up insurance producer. The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument, whether the financial instrument is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires significantly more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in the Level 3 hierarchy. The Company uses prices and inputs that are current as at the measurement date. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified between hierarchy levels. For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these in the Level 1 hierarchy. The Company receives the quoted market prices from a third party nationally recognized provider ("the Pricing Service"). When quoted market prices are unavailable, the Company utilizes the Pricing Service to determine an estimate of fair value. The fair value estimates are included in the Level 2 hierarchy. The Company will challenge any prices for its investments which are considered not to be representative of fair value. If quoted market prices and an estimate from the Pricing Service are unavailable, the Company produces an estimate of fair value based on dealer quotations for recent activity in positions with the same or similar characteristics to that being valued. The Company determines whether the fair value estimate is in the Level 2 or Level 3 hierarchy depending on the level of observable inputs available when estimating the fair value. The Company bases its estimates of fair values for assets on the bid price as it represents what a third party market participant would be willing to pay in an orderly transaction. ASC 825, "Disclosure About Fair Value of Financial Instruments" , requires all entities to disclose the fair value of their financial instruments for assets and liabilities recognized and not recognized in the balance sheet, for which it is practicable to estimate fair value. The following describes the valuation techniques used by the Company to determine the fair value of financial instruments that are measured at fair value on a recurring basis held at September 30, 2021 and December 31, 2020. U.S. government and U.S. agency — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, Federal National Mortgage Association and the Federal Farm Credit Banks Funding Corporation. The fair values of U.S. treasury bonds are based on quoted market prices in active markets, and are included in the Level 1 fair value hierarchy. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. agency bonds are included in the Level 2 fair value hierarchy. Non-U.S. government and supranational bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government and supranational bonds are observable market inputs, the fair values of non-U.S. government and supranational bonds are included in the Level 2 fair value hierarchy. 5. Fair Value Measurements (continued) Asset-backed securities — These securities comprise commercial mortgage-backed securities ("CMBS") and collateralized loan obligations ("CLO") originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS and CLO are observable market inputs, their fair values are included in the Level 2 fair value hierarchy. Corporate and municipal bonds — Bonds issued by corporations, U.S. state and municipality entities or agencies that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The credit spreads are sourced from broker/dealers, trade prices and new issue market. Where pricing is unavailable from pricing services, custodian pricing or non-binding quotes are obtained from broker-dealers to estimate fair values. As significant inputs used to price corporate and municipal bonds are observable market inputs, fair values are included in the Level 2 fair value hierarchy. Equity securities - The fair value of equity securities is primarily priced by pricing services, reflecting the closing price quoted for the final trading day of the period. The common stock is carried at fair value using observable market pricing data and is included in the Level 1 fair value hierarchy. Any unrealized gains or losses on the investment is recorded in net income in the period in which they occur. Other investments — Includes unquoted investments comprised of the following investments: • Privately held investments: These are direct equity investments in common and preferred stock of privately held entities. The fair values are estimated using quarterly financial statements and/or recent private market transactions and thus included under Level 3 of the fair value hierarchy due to unobservable market data used for valuation. These investments are also comprised of investments in insurtech and other insurance focused companies. The fair value of these start-up insurance entities are determined using recent private market transactions where applicable and included in the Level 3 fair value hierarchy due to unobservable market data used for valuation. • Private credit funds: These are privately held equity investments in common stock of entities that lend money valued using the most recently available or quarterly net asset value ("NAV") statements as provided by the external fund manager or third-party administrator and therefore measured using the NAV as a practical expedient. • Private equity funds: These are comprised of private equity funds, private equity co-investments with sponsoring entities and investments in real estate limited partnerships and joint ventures . The fair value is estimated based on the most recently available NAV as advised by the external fund manager or third-party administrator. The fair values are therefore measured using the NAV as a practical expedient.
