Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Maiden Holdings, Ltd. (sometimes referred to as "Maiden Holdings" or "Parent Company") is a Bermuda-based holding company. Together with its subsidiaries (collectively referred to as the "Company", "We" or "Maiden"), Maiden previously focused on serving the needs of regional and specialty insurers in the United States of America ("U.S."), Europe and select other global markets. The Company operates internationally through Maiden Global Holdings, Ltd. ("Maiden Global") providing branded auto and credit life insurance products through insurer partners to retail clients in the EU and other global markets. These products also produce reinsurance programs which are underwritten by Maiden Reinsurance Ltd. ("Maiden Reinsurance"). Maiden Reinsurance does not underwrite any direct insurance business. Certain international credit life business is written on a primary basis by Maiden Life Försäkrings AB ("Maiden LF") and general insurance business is written on a primary basis by Maiden General Försäkrings AB ("Maiden GF"). We are not presently actively underwriting reinsurance business. We are also running off the liabilities associated with AmTrust Financial Services, Inc. ("AmTrust") contracts we terminated in early 2019 as discussed below. Strategic Review Since 2018, we have engaged in a series of strategic measures that have dramatically reduced the required regulatory capital needed to operate our business, materially strengthened our solvency ratios, re-domiciled Maiden Reinsurance to Vermont in the U.S. and ceased active reinsurance underwriting. During that time, we significantly increased our estimate of ultimate losses and loss reserves while purchasing reinsurance protection against further loss reserve volatility and as a result, have improved the ultimate economic value of the Company. We believe these measures have given the Company the ability to more flexibly allocate capital to those activities most likely to produce the greatest returns for shareholders. The measures we ultimately have taken were initiated in early 2018, when our Board of Directors initiated a review of strategic alternatives (the "Strategic Review") to evaluate ways to increase shareholder value after a period of continuing higher than targeted combined ratios and lower returns on equity than planned. In addition, as of December 31, 2018, both the Company and its subsidiary Maiden Reinsurance failed to meet their requirements to hold sufficient capital to cover their respective enhanced capital requirements (“ECR”). The Company had communicated such conditions to the Bermuda Monetary Authority ("BMA") and is following the guidelines of a reportable “event” as stipulated by Bermuda insurance law. As part of both the Strategic Review and the remediation measures implemented to cure the breach of the ECR, a series of transactions were entered into including: (1) completed the sale of Maiden Reinsurance North America, Inc. ("Maiden US") on December 27, 2018; (2) Maiden Reinsurance's shareholders, Maiden Holdings and Maiden Holdings North America, Ltd. ("Maiden NA"), made capital injections of $125,000 on December 31, 2018 and $70,000 on January 18, 2019 to Maiden Reinsurance from the sale proceeds of Maiden US; (3) entered into a partial termination amendment ("Partial Termination Amendment") with AmTrust effective January 1, 2019 which amended the quota share reinsurance agreement (“AmTrust Quota Share”) between Maiden Reinsurance and AmTrust’s wholly owned subsidiary AmTrust International Insurance, Ltd. (“AII”) (as more fully described in "Note 8 - Reinsurance" ); (4) entered into amendments which terminated the AmTrust Quota Share 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") effective January 1, 2019 (these transactions are broadly referred to herein as the "Final AmTrust QS Terminations"); (5) entered into the Loss Portfolio Transfer and Adverse Development Cover Agreement ("LPT/ADC Agreement") with Enstar Group Limited ("Enstar') pursuant to the revised Master Transaction Agreement entered into on March 1, 2019; and (6) entered into a Commutation and Release Agreement with AmTrust to commute certain workers' compensation business with AII as of January 1, 2019. As a result of the completion of these steps, both the Company and Maiden Reinsurance have sufficient capital in excess of the respective ECR requirements. Please see below for additional details regarding the LPT/ADC Agreement and the Commutation and Release Agreement. Discontinued Operations The Company made the strategic decision to divest its U.S. treaty reinsurance operations through the sale of Maiden US which was completed on December 27, 2018. Except as explicitly described as held for sale or as discontinued operations, and unless otherwise noted, all discussions and amounts presented herein relate to the Company's continuing operations except for net loss, net loss attributable to Maiden and net loss attributable to Maiden common shareholders. Sale of U.S. treaty reinsurance operations The sale of the U.S. treaty reinsurance business occurred in two parts: (a) On August 29, 2018, the Company entered into a Renewal Rights Agreement ("Renewal Rights") with Transatlantic Reinsurance Company ("TransRe"), pursuant to which the Company sold, and TransRe purchased, Maiden US's rights to: (i) renew Maiden US’s treaty reinsurance agreements upon their expiration or cancellation, (ii) solicit renewals of and replacement coverages for the treaty reinsurance agreements and (iii) replicate and use the products and contract forms used in Maiden US’s business. The sale was consummated on August 29, 2018. The Company continues to earn premiums and remain liable for losses occurring subsequent to August 29, 2018 for any policies in force prior to and as of August 29, 2018, until those policies expire. The payment received for the sale of the Renewal Rights was $7,500 subject to potential additional amounts payable in the future in accordance with the agreement, however no additional fees have been recognized to date. 1. Organization (continued) (b) On December 27, 2018, the Company completed its sale agreement ("U.S. Sale Agreement") with Enstar Holdings (US) LLC ("Enstar U.S."), pursuant to which Maiden NA sold Maiden US to Enstar U.S. Pursuant to and subject to the terms of the U.S. Sale Agreement: (i) Maiden NA sold, and Enstar U.S. purchased, all of the outstanding common shares of Maiden US (“Maiden US Sale”) for gross consideration of $286,375 ; (ii) Cavello Bay Reinsurance Limited ("Cavello"), Enstar’s Bermuda reinsurance affiliate, and Maiden Reinsurance entered into an agreement pursuant to which certain quota share reinsurance contracts between Maiden US and Maiden Reinsurance were novated to Cavello for a ceding commission Maiden Reinsurance of $12,250 ; (iii) Cavello and Maiden Reinsurance also entered into a retrocession agreement pursuant to which certain assets and liabilities associated with the Company’s U.S. treaty reinsurance business held by Maiden Reinsurance were retroceded to Cavello in exchange for a $1,750 ceding commission; and (iv) Maiden Reinsurance provided Enstar with a reinsurance cover for loss reserve development, up to a maximum of $25,000 , when losses are more than $100,000 in excess of the net loss and loss adjustment expenses recorded as of June 30, 2018, for no additional consideration. As discussed above, Maiden NA completed the sale of Maiden US to Enstar U.S. for gross consideration of $286,375 , which was subject to certain post-closing adjustments. In conjunction with the completion of the LPT/ADC Agreement discussed below, on July 31, 2019, Maiden NA and Enstar U.S. waived the post-closing adjustments set forth in the U.S. Sale Agreement and agreed to terminate the $25,000 excess of loss reinsurance agreement that Maiden Reinsurance provided to Enstar in relation to the Maiden US loss reserves acquired by Enstar. As a result of these agreements, Maiden recorded a net additional loss from discontinued operations of $16,714 for the year ended December 31, 2019 . The Company determined that the sale of the U.S. treaty reinsurance operations represented a strategic shift that has a major effect on its ongoing operations and financial results and that all of the held for sale criteria were met. Accordingly, all transactions related to the U.S. treaty reinsurance operations have been reported and presented as part of discontinued operations. Please refer to " Note 2. Significant Accounting Policies " and " Note 6. Discontinued Operations " for additional information regarding the effect of the reclassifications on the Company's Consolidated Financial Statements. LPT/ADC Agreement with Enstar Pursuant to the LPT/ADC Agreement dated as of July 31, 2019 and effective as of January 1, 2019 entered into between Maiden Reinsurance and Cavello, 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 therefore has been accounted for as retroactive reinsurance. Cumulative ceded losses exceeding $445,000 result in a deferred gain which will be recognized over the settlement period in proportion to cumulative losses collected over the estimated ultimate reinsurance recoverable. 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. At December 31, 2019 , the deferred gain liability recorded for retroactive reinsurance under the LPT/ADC Agreement was $112,950 . 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 . Under the terms of the LPT/ADC Agreement, the covered losses associated with the commutation with AmTrust, as discussed below in Commutation and Release Agreement - AmTrust Quota Share, 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 . Settlement of funding for the LPT/ADC Agreement occurred on August 12, 2019 and Maiden Reinsurance paid Enstar approximately $7,261 in interest related to the LPT/ADC Agreement premium, calculated at the rate of 2.64% per annum from January 1, 2019 through August 12, 2019 . Commutation and Release Agreement - AmTrust Quota Share Effective July 31, 2019, Maiden Reinsurance and AII entered into the Commutation and Release Agreement which provided for AII to re-assume all reserves ceded by AII to Maiden Reinsurance with respect to: (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 from all of its 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. Maiden Reinsurance transferred cash and invested assets in the amount of $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. Settlement of the Commutation Payment occurred 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 . Maiden Reinsurance received a no objection letter from the BMA regarding the Commutation and Release Agreement. 1. Organization (continued) Re-domestication of Maiden Reinsurance During the fourth quarter of 2019, our principal operating subsidiary, Maiden Reinsurance, submitted the necessary filings to discontinue its operations from Bermuda and to apply to be licensed and re-domesticate to the State of Vermont in the U.S. Filings were made with the Vermont Department of Financial Regulation ("Vermont DFR"), the Vermont Secretary of State as well as with the BMA to provide notice of the Company's intent to discontinue from Bermuda and re-domesticate to Vermont. Maiden Reinsurance completed the re-domestication to the State of Vermont on March 16, 2020. We have determined that re-domiciling Maiden Reinsurance to Vermont will enable us to better align our operations, capital and resources with our liabilities, which originate mostly in the U.S., resulting in a more efficient structure.The re-domestication, in combination with the Strategic Review previously taken and undertaken in close consultation with the BMA to de-risk the Company’s balance sheet, is expected to continue to strengthen the Company’s capital position and solvency ratios. While the Vermont DFR will become the group supervisor for the Company, the re-domestication does not apply to the parent holding company which remains a Bermuda-based holding company. Securities issued by Maiden Holdings are not affected by the re-domestication of Maiden Reinsurance to Vermont. Segments As a result of the strategic decision to divest all of the Company's U.S. treaty reinsurance operations noted above, the Company revised the composition of its reportable segments. As described in more detail under “ Note 3 — Segment Information ”, the reportable segments include: (i) Diversified Reinsurance which consists of a portfolio of property and casualty reinsurance business focusing on regional and specialty property and casualty insurance companies located primarily in Europe; and (ii) AmTrust Reinsurance which includes all business ceded to Maiden Reinsurance from subsidiaries of AmTrust. In addition to these reportable segments, the results of operations of the former National General Holdings Corporation Quota Share ("NGHC Quota Share") segment, which was commuted in November 2019, is included in the "Other" category. Certain prior year comparatives have been reclassified to conform to this new presentation.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Reporting and Consolidation — These Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the U.S. ("U.S. GAAP") and include the accounts of Maiden Holdings and all of its subsidiaries. These Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the period and all such adjustments are of a normal recurring nature. All significant intercompany transactions and accounts have been eliminated. 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 loss. As part of the Strategic Review initiated by the Company's Board of Directors in 2018, the Company made the strategic decision to divest its U.S. treaty reinsurance operations through the sale of Maiden US, completed on December 27, 2018, which had a major effect on its ongoing operations and financial results. Accordingly, all of the remaining assets and liabilities related to the true up of sale consideration are classified as held for sale in the Consolidated Balance Sheet as at December 31, 2018 . The operating results of the Company's U.S. treaty reinsurance business for the years ended December 31, 2019 and 2018 have been reclassified and presented as part of discontinued operations in the Consolidated Statements of Income. Except as explicitly described as held for sale or as discontinued operations, and unless otherwise noted, all discussions and amounts presented herein relate to the Company's continuing operations except for net loss, net loss attributable to Maiden and net loss attributable to Maiden common shareholders. Please see “ Note 6 — Discontinued Operations " for additional information related to discontinued operations. Estimates — The preparation of U.S. GAAP Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. The significant estimates include, but are not limited to, reserve for loss and loss adjustment expenses ("loss and LAE") and deferred gain on retroactive reinsurance; recoverability of reinsurance balances receivable, reinsurance recoverable on unpaid losses and deferred commission and other acquisition expenses; valuation of financial instruments and deferred tax assets; and the determination of other-than-temporary impairment ("OTTI") of investments. Investments — The Company has historically classified its fixed maturity investments as either available-for-sale ("AFS") or held-to-maturity ("HTM"). The AFS portfolio is reported at fair value and any unrealized gains or losses are reported as a component of accumulated other comprehensive income ("AOCI"). The HTM portfolio at December 31, 2018 included securities for which the Company had the ability and intent to hold to maturity or redemption and was reported at amortized cost. When a security was transferred from AFS to HTM, the fair value at the time of transfer, adjusted for subsequent amortization, became the security's amortized cost. The net unrealized holdings gains of securities transferred from AFS to HTM at the designation date continue to be reported in the carrying value of the HTM securities and is amortized through other comprehensive income over the remaining life of the securities using the effective yield method in a manner consistent with the amortization of any premium or discount. When a security transferred from HTM to AFS, the security’s amortized cost basis carried over to the AFS category for subsequent amortization of the historical premium or discount, comparisons of fair value and amortized cost for determining unrealized holding gains and losses, and required disclosures of amortized cost. The difference between the security’s amortized cost and fair value at the date of transfer into the AFS portfolio is recognized as an unrealized gain or loss and recorded in AOCI. Due to the termination of both AmTrust quota share contracts effective January 1, 2019, the Company no longer believed that it had the positive ability to hold the securities in the HTM portfolio to maturity because this portfolio served as part of the collateral for the AmTrust Reinsurance segment loss reserves. Therefore, the Company reclassified and transferred all HTM securities to the AFS portfolio in the first quarter of 2019. Please see " Note 4 — Investments " for further details. The fair value of fixed maturity investments is generally determined from quotations received from third-party nationally recognized pricing services ("Pricing Service"), or when such prices are not available, by reference to broker or underwriter bid indications. Short-term investments comprise securities due to mature within one year of the date of purchase. The Company held no short-term investments as at December 31, 2019 and 2018 . The Company's other investments comprise of unquoted investments. The Company accounts for its unquoted other investments at fair value in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 944-325, "Financial Services - Insurance - Investments - Other" ("ASC 944-325"). Unquoted other investments are comprised of investments in limited partnerships, which are reported at fair value based on the financial information received from the fund managers and other information available to management with changes in fair value recognized in net income, as well as investments in start-up insurance entities which are reported at fair value using recent private market transactions. Investments made by special purpose vehicles focused on lending activities are carried at cost less impairment, if any. Any indication of impairment is recognized in income when determined. Purchases and sales of investments are recorded on a trade date basis. Realized gains or losses on sales of investments are determined based on the first in first out cost method. Net investment income is recognized when earned and includes accrued interest and dividend income together with amortization of market premiums and discounts using the effective yield method, net of investment management fees. For U.S. government agency mortgage-backed securities ("Agency MBS") and any other holdings for which there is a prepayment risk, prepayment assumptions are evaluated and revised as necessary. Any adjustments required due to the change in effective yields and maturities are recognized on a prospective basis through yield adjustments. 2. Significant Accounting Policies (continued) A security is potentially impaired when its fair value falls below its amortized cost. On a quarterly basis, all potentially impaired securities are reviewed to determine whether the impairment is temporary or OTTI. OTTI assessments are inherently judgmental, especially where securities have experienced severe declines in fair value over a short period. The Company's review process begins with a quantitative analysis to identify securities to be further evaluated for potential classification as OTTI. For all identified securities, further fundamental analysis is performed that considers, but is not limited to, the following quantitative and qualitative factors: historic and implied volatility of the security; length of time and extent to which the fair value has been less than amortized cost; adverse conditions specifically related to the security or to specific conditions in an industry or geographic area; failure, if any, of the issuer of the security to make scheduled payments; and recoveries or additional declines in fair value subsequent to the balance sheet date. The Company recognizes OTTI losses within earnings for its impaired fixed maturity securities (i) for which the Company has the intent to sell the security or (ii) it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery and (iii) for those securities which have a credit loss. In assessing whether a credit loss exists, the Company compares the present value of the cash flows expected to be collected from the security with the amortized cost basis of the security. In instances in which a determination is made that an impairment exists but the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining amortized cost basis, the impairment is separated into (i) the amount of the total impairment related to the credit loss and (ii) the amount of the total impairment related to all other factors. The amount of the total OTTI related to the credit loss is recognized in earnings. The amount of the total OTTI related to all other factors is recognized in other comprehensive income. In periods after the recognition of OTTI on the fixed maturity securities, the Company accounts for such securities as if they had been purchased on the measurement date of the OTTI at an amortized cost basis equal to the previous amortized cost basis less the OTTI recognized in earnings. For fixed maturity securities in which an OTTI loss was recognized in earnings, the difference between the new amortized cost basis and the cash flows expected to be collected will be amortized into net investment income. As the Company's investment portfolio is the largest component of its consolidated assets, any OTTI on fixed maturity securities could be material to the Company's financial condition and results particularly during periods of dislocation in the financial markets. Fair Value Measurements — ASC 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 as follows: • Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since 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 severities, 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. 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 a financial instrument to be reclassified between levels. For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these prices in the amounts disclosed in the Level 1 fair value hierarchy. The Company receives the quoted market prices from the Pricing Service which is a third-party nationally recognized provider. 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 fair value hierarchy. The Company challenges any prices for its investments which are considered not to be representative of fair value. If quoted market prices and estimates 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 investment being valued or through consensus pricing of a pricing service. 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 fair value. The Company bases its estimates of fair values for assets on the bid price as it represents the price a third-party market participant would be willing to pay in an orderly transaction. 2. Significant Accounting Policies (continued) Cash and Cash Equivalents — The Company maintains cash accounts in several banks and brokerage institutions. Cash equivalents consist of investments in money market funds and short-term investments with an original maturity of 90 days or less and are stated at cost, which approximates fair value. Restricted cash and cash equivalents are separately reported in the Consolidated Balance Sheets. The Company maintains certain cash and investments in trust accounts used primarily as collateral for unearned premiums and loss and LAE reserves owed to insureds. The Company is required to maintain minimum balances in these restricted accounts based on pre-determined formulas. Please see " Note 4. (e) Investments " for additional details. Premiums and Related Expenses — For pro-rata contracts and excess-of-loss contracts where no deposit or minimum premium is specified in the contract, premium written is recognized based on estimates of ultimate premiums provided by the ceding companies. Initial estimates of premium written are recognized in the period in which the underlying risks are incepted. Subsequent adjustments, based on reports of actual premium by the ceding companies, or revisions in estimates, are recorded in the period in which they are determined. Reinsurance premiums assumed are generally earned on a pro-rata basis over the terms of the underlying policies or reinsurance contracts. Contracts and policies written on a "losses occurring" basis cover claims that may occur during the term of the contract or policy, which is typically twelve months. Accordingly, the premium is earned evenly over the term. Contracts which are written on a "risks attaching" basis cover claims which attach to the underlying insurance policies written during the terms of such contracts. Premiums earned on such contracts usually extend beyond the original term of the reinsurance contract, typically resulting in recognition of premiums earned over a 24-month period. Reinsurance premiums on specialty risk and extended warranty are earned based on the estimated program coverage period. These estimates are based on the expected distribution of coverage periods by contract at inception, because a single contract may contain multiple coverage period options, and these estimates are revised based on the actual coverage period selected by the original insured. Unearned premiums represent the portion of premiums written which is applicable to the unexpired term of the contract or policy in force. These premiums can be subject to estimates based upon information received from ceding companies and any subsequent differences arising on such estimates are recorded in the period in which they are determined. Assumed and ceded reinsurance contracts that lack a significant transfer of risk are treated as deposits. No deposit contracts are held as at December 31, 2019 and 2018 . Acquisition expenses represent the costs of writing business that vary with, and are primarily related to, the production of that business. Policy and contract acquisition expenses, including assumed commissions, are deferred and recognized as expense as the related premiums are earned. The Company considers anticipated investment income in determining the recoverability of these costs and believes they are fully recoverable. A premium deficiency is recognized if the sum of anticipated losses and loss adjustment expenses, unamortized acquisition expenses less anticipated investment income exceed unearned premiums. Loss and Loss Adjustment Expenses Incurred — Loss and LAE represent the estimated ultimate net costs of all reported and unreported losses incurred through December 31 of the latest fiscal year. The reserve for loss and LAE is estimated using a statistical analysis of actuarial data and is not discounted for the time value of money. Although considerable variability is inherent in the estimates of reserves for loss and LAE, management believes that the reserve for loss and LAE is adequate based on known information to date. In estimating loss reserves, the Company utilizes a variety of standard actuarial methods. These estimates are continually reviewed and adjusted as necessary as experience develops or new information becomes available. Such adjustments are included and reported in current operations as favorable or unfavorable prior period development. Reinsurance — Reinsurance premiums and loss and LAE ceded to other companies are accounted for on a basis consistent with those used in accounting for original policies issued and pursuant to the terms of the reinsurance contracts. The Company records premiums earned and loss and LAE incurred and ceded to other companies as reduction of premium revenue and loss and LAE, respectively. The unexpired portion of reinsurance purchased by the Company (retrocession or reinsurance premiums ceded) is included in other assets and amortized over the contract period in proportion to the amount of insurance protection provided. The ultimate amount of premiums, including adjustments, is recognized as premiums ceded and amortized over the applicable contract period to which they apply. Premiums earned are reported net of reinsurance in the Consolidated Statements of Income. Reinsurance recoverable on unpaid losses relate to the portion of reserves and paid losses and LAE that are ceded to other companies. Reinsurance recoverable on unpaid losses are separately recorded as an asset in the Consolidated Balance Sheets. The Company remains contingently liable for all loss payments in the event of failure to collect from reinsurers. Accounting for Retroactive Reinsurance Agreements - Retroactive reinsurance agreements are reinsurance agreements under which a reinsurer agrees to reimburse the Company as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability which is amortized into income over the settlement period of the ceded reserves once the paid losses have exceeded the minimum retention. The amount of the deferral is recalculated each period based on actual loss payments and updated estimates of ultimate losses. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the retroactive reinsurance agreement is recognized within income immediately. On July 31, 2019, Maiden Reinsurance entered into the LPT/ADC Agreement as discussed in " Note 1 — Organization " . This transaction was accounted for as retroactive reinsurance pursuant to U.S. GAAP and a deferred gain liability is recognized for the amount which represents the cumulative adverse development of losses subject to the LPT/ADC Agreement. Amortization of the deferred gain will not begin until paid losses have exceeded the minimum retention under this agreement, which is estimated to be in 2024 . 2. Significant Accounting Policies (continued) Debt Obligations and Deferred Debt Issuance Costs — Costs incurred in issuing debt are capitalized and amortized over the contractual life of the debt. The amortization of these costs are included in interest and amortization expenses in the Consolidated Statements of Income. The unamortized amount of issuance costs is presented as a deduction from the related principal liability for senior notes in the Consolidated Balance Sheets. Leases — The Company's leases are all currently classified as operating leases and none of them have non-lease components. For operating leases that have a lease term of more than twelve months, the Company recognized a lease liability (presented as part of accrued expenses and other liabilities) and a right-of-use asset (presented as part of other assets) in the Company's 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 a weighted-average discount rate of 10% , representing its estimated secured incremental borrowing rate, in calculating the present value of the lease liability. The Company has made an accounting policy election not to include renewal, termination, or purchase options that are not reasonably certain of exercise when determining the term of the borrowing. The Company recognizes the related leasing expense on a straight-line basis over the lease term in the Company's Consolidated Statements of Income. Goodwill and Intangible Assets — A purchase price that is in excess of the fair value of the net assets acquired arising from a business combination is recorded as goodwill and is not amortized. Other intangible assets with a finite life are amortized over the estimated useful life of the asset. Intangible assets with an indefinite useful life are not amortized similar to goodwill. Goodwill and other indefinite life intangible assets were historically tested for impairment on an annual basis or more frequently if events or changes in circumstances indicated that the carrying amount may not be recoverable. Finite life intangible assets were reviewed for indicators of impairment on an annual basis or more frequently if events or changes in circumstances indicated that the carrying amount may not be recoverable, and tested for impairment if appropriate. For purposes of the annual impairment evaluation, goodwill was assigned to the applicable reporting unit of the acquired entities giving rise to the goodwill. The Company had established October 1 as the date for performing the annual impairment tests or when “triggering events” occur or circumstances changed that could have potentially reduced the fair value of a reporting unit below its carrying amount. Goodwill was considered impaired if the carrying amount of the reporting unit exceeded its fair value. If goodwill or other intangible assets were impaired, they were written down to their estimated fair values with a corresponding loss reflected in the Consolidated Statements of Income. The announced sale of the Company's U.S. treaty reinsurance operations resulted in a triggering event and consequently during the year ended December 31, 2018 , the remaining balance of goodwill and intangible assets was written off as they were deemed to be permanently impaired due to the sale of the U.S. treaty reinsurance renewal rights and the sale of the U.S. Diversified Reinsurance business. Please refer to " Note 6 — Discontinued Operations " for further details of this disposal. Noncontrolling Interests — The Company accounts for noncontrolling interests in subsidiaries in accordance with ASC Topic 810 " Consolidations" , and presents any noncontrolling shareholders' interest in the equity section of the Consolidated Balance Sheets. Net income attributable to noncontrolling interests is presented separately in the Consolidated Statements of Income. There are no remaining noncontrolling interests in subsidiaries as at December 31, 2019 . Income Taxes — The Company accounts for income taxes using ASC Topic 740 " Income Taxes" for subsidiaries operating in taxable jurisdictions. Deferred income taxes reflect the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. A valuation allowance is recorded if it is more likely than not that some or all of a deferred tax asset may not be realized. The Company considers future taxable income and feasible tax planning strategies in assessing the need for a valuation allowance. In the event the Company determines that it will not be able to realize all or part of its deferred income tax assets in the future, an adjustment to the deferred income tax assets would be charged to income in the period in which such determination is made. In addition, if the Company subsequently assesses that the valuation allowance is no longer needed, a benefit would be recorded to income in the period in which such determination is made. U.S. GAAP allows for the recognition of tax benefits of uncertain tax positions only where the position is more likely than not to be sustained assuming examination by tax authorities. A liability is established for any tax benefit claimed in a tax return in excess of this threshold. Income tax related interest and penalties would be included as income tax expense. The Company has not recorded or accrued any interest or penalties during the years ended December 31, 2019 and 2018 . Share-Based Compensation Expense — The Company is authorized to issue restricted share awards and units, performance based restricted share units ("PB-RSUs"), share options and other equity-based awards to its employees and directors. The Company recognizes the compensation expense for share options, restricted share and share unit grants, based on the fair value of the award on the date of grant, over the requisite service vesting period. Forfeitures are accounted for when they occur. The estimated fair value of the grant will be amortized ratably over its vesting period as a charge to compensation expense (a component of general and administrative expenses) and an increase to additional paid-in capital in Consolidated Shareholders’ Equity. The estimated fair value of the PB-RSUs is recognized as a charge to compensation expense and an increase to additional paid-in capital in Consolidated Shareholders’ Equity following the satisfaction of certain criteria during the specified performance period. Forfeitures are accounted for if and when they occur. Earnings Per Share — Basic earnings per share are computed based on the weighted-average number of common shares outstanding and exclude any dilutive effects of options, restricted share units ("RSUs") and PB-RSUs. Dilutive earnings per share are computed using the weighted-average number of common shares outstanding during the period adjusted for the dilutive impact of share options, RSUs and PB-RSUs. 2. Significant Accounting Policies (continued) The two-class method is used to determine earnings per share based on dividends declared on common shares and participating securities (i.e. distributed earnings) and participation rights of participating securities in any undistributed earnings. Each unvested restricted share granted by the Company to certain senior leaders is considered a participating security and the two-class method is used to calculate net income attributable to Maiden common shareholders per common share – basic and diluted. However, any undistributed losses are not allocated to the participating securities. Treasury Shares — Treasury shares include common shares repurchased by the Company and not subsequently cancelled as well as share repurchases from employees, which represent withholdings in respect of tax obligations on the vesting of restricted shares and performance based shares. These shares are recorded at cost and result in a reduction of the total Maiden shareholders’ equity in the Consolidated Balance Sheets. Foreign Currency Transactions — The functional currency of the Company and many of its subsidiaries is the U.S. dollar. For these companies, monetary assets and liabilities denominated in foreign currencies are translated at year-end exchange rates, with resulting foreign exchange gains and losses recognized in the Consolidated Statements of Income. Revenues and expenses in foreign currencies are converted at average exchange rates during the year. Monetary assets and liabilities include cash and cash equivalents, reinsurance balances receivable, reinsurance recoverable on unpaid losses, funds withheld receivable, reserve for loss and LAE and accrued expenses and other liabilities. Accounts that are classified as non-monetary such as deferred commission and other acquisition expenses and unearned premiums are not revalued. Assets and liabilities of foreign subsidiaries and divisions, whose functional currency is not the U.S. dollar, are translated at year-end exchange rates. Revenues and expenses of these entities are translated at average exchange rates during the year. The effects of the foreign currency translation adjustment for foreign entities are included in AOCI. The amount of the cumulative translation adjustment at December 31, 2019 was $(4,160) ( 2018 - $(5,854) ). Recently Adopted Accounting Standards Updates Improvements to Non-employee Share-Based Payment Accounting In June 2018, the FASB issued Accounting Standards Update ("ASU") 2018-07 that simplifies the accounting for share-based payments granted to non-employees for goods and services. Under the guidance, payments to non-employees would be aligned with the requirements for share-based payments granted to employees as FASB viewed the awards to both employees and non-employees to be economically similar and thus two different accounting models were not justified. The Company currently measures directors’ share-based payment awards at fair value as at their grant date; therefore the adoption of this standard on January 1, 2019 did not have any impact on the Company’s Consolidated Financial Statements. Codification Improvements In July 2018, the FASB issued ASU 2018-09 which includes clarifications to existing codifications or corrections of unintended application of guidance not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments in this update include items raised for board consideration through the codification's feedback system that met the scope of this project, making the due diligence process necessary. The amendments affect a wide variety of topics in the codification and apply to all reporting entities within the scope of the affected accounting guidance. None of the topics deemed applicable upon adoption of this standard on January 1, 2019 had a material impact on the financial statements. Topic 842, Leases In July 2018, the FASB issued ASU 2018-11 for targeted improvements related to ASU 2016-02 which provide entities with an additional transition method to apply the new leasing standard. Under the new optional transition method, an entity initially app

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 by AmTrust, primarily the AmTrust Quota Share and the European Hospital Liability Quota Share, which are in run-off effective January 1, 2019. In addition to our reportable segments, the results of operations of the former NGHC Quota Share segment, which was commuted in November 2019, have been included in the "Other" category. Please refer to " Note 10. Related Party Transactions " for additional information. As a result of the strategic decision to divest all of the Company's U.S. treaty reinsurance operations as discussed in " Note 1. Organization " and " Note 6. Discontinued Operations ", the Company revised the composition of its reportable segments. Previously, the underwriting results associated with the discontinued operations of the Company's U.S. treaty reinsurance business were included within the Diversified Reinsurance segment and the operating results associated with the remnants of the U.S. excess and surplus business were included within the Other category. These are now excluded and all prior periods presented have been reclassified to conform to this new presentation. 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 reportable 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, loan to related party, restricted cash and investments, and funds withheld receivable. All remaining assets are allocated to Corporate. As discussed in "Note 1. Organization" and "Note 10. Related Party Transactions" , the Partial Termination Amendment and the termination of the remaining business with AmTrust effective January 1, 2019 resulted in a significant reduction in gross premiums written. This was due to the return of unearned premium on certain lines covered by the Partial Termination Amendment, with no new business written in 2019 as a result of the termination of the AmTrust Quota Share and the European Hospital Liability Quota Share.

The HTM portfolio at December 31, 2018 included securities for which we had the ability and intent to hold to maturity or redemption and was reported at amortized cost. However, due to the termination of both AmTrust quota share contracts effective January 1, 2019, the Company no longer believed that it had the positive ability to hold the securities in the HTM portfolio to maturity because the HTM portfolio was part of the collateral for the AmTrust Reinsurance segment loss reserves. Therefore, the Company reclassified and transferred all HTM securities to the AFS portfolio at their fair market value as at March 31, 2019 . The carrying value of the HTM securities at the time of transfer was $1,011,878 and the related unrealized gains of $14,230 were added to AOCI. The contractual maturities of our fixed maturities are shown in the table below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investments (continued) At December 31, 2019 , there were approximately 104 securities in an unrealized loss position with a fair value of $386,299 and unrealized losses of $17,639 . Of these securities, there were 67 securities that have been in an unrealized loss position for 12 months or greater with a fair value of $262,519 and unrealized losses of $16,815 .

Of these securities, there were 103 securities that have been in an unrealized loss position for 12 months or greater with a fair value of $1,188,564 and unrealized losses of $52,253 . OTTI The Company performs quarterly reviews of its fixed maturities in order to determine whether declines in fair value below the amortized cost basis should be considered other-than-temporary in accordance with applicable guidance. At December 31, 2019 , we determined that unrealized losses on fixed maturities were primarily due to interest rates rising 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 the Company is 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 our analysis, our fixed maturity portfolio is of high credit quality and believe the amortized cost basis of the securities will be ultimately recovered. The Company continually monitors the credit quality of the fixed maturity investments to assess if it is probable that we will receive our contractual or estimated cash flows in the form of principal and interest. For the year ended December 31, 2019 , the Company recognized $165 in OTTI charges in earnings on one fixed maturity security ( 2018 - $5,832 on seventy-two fixed maturity securities).

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements a) Fair Values of Financial Instruments ASC 825, "Disclosure About Fair Value of Financial Instruments" , requires all entities to disclose the fair value of their financial instruments for both assets and liabilities recognized and not recognized within the balance sheet, and 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 held at December 31, 2019 and 2018 . U.S. government and U.S. agency — Bonds issued by the U.S. Treasury, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association and the Federal National Mortgage Association. 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. The Company believes 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 credit spread above the risk-free yield curve. As the yields for the risk-free yield curve and the credit 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 attributes. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate credit 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 are included in the Level 2 fair value hierarchy. Asset-backed securities — These securities comprise CMBS and 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. 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, the 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 the 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 the significant inputs used to price corporate and municipal bonds are observable market inputs, the fair values are included in the Level 2 fair value hierarchy. Other investments — Includes unquoted investments comprised of investments in limited partnerships and other investments which includes investments in special purpose vehicles focused on lending activities as well as investments in start-up insurance entities. The fair values of the investments in limited partnerships are determined by the fund manager based on recent filings, operating results, balance sheet stability, growth and other business and market sector fundamentals. The fair value of these investments are measured using the NAV practical expedient and therefore have not been categorized within the fair value hierarchy. If there is a reporting lag between the current period end and the reporting date of the latest available fund valuation, fair values are estimated by starting with the most recently available valuation and adjusting for return estimates as well as any subscriptions and distributions that took place during the current period. The investments made by special purpose vehicles focused on lending activities are carried at cost less impairment, if any, with any indication of impairment recognized in income when determined. As these investments are carried at cost, they are not included in the fair value hierarchy below. The fair value of the start-up insurance entities are determined using recent private market transactions and as such, the fair value of these investments are included in the Level 3 fair value hierarchy. Cash and cash equivalents (including restricted amounts), accrued investment income, reinsurance balances receivable and certain other assets and liabilities — The carrying values reported in the Consolidated Balance Sheets for these financial instruments approximate their fair value due to their short term nature and are classified within the Level 2 fair value hierarchy. Loan to related party, reinsurance recoverable on unpaid losses and funds withheld receivable — The carrying values reported in the Consolidated Balance Sheets for these financial instruments approximate their fair value and are included in the Level 2 fair value hierarchy. Senior notes — The carrying value for these financial instruments includes the principal amounts of the notes less any unamortized issuance costs. The fair values of the senior notes are based on indicative market pricing obtained from a third-party service provider and, as such, are included in the Level 2 fair value hierarchy. b) Fair Value Hierarchy The Company’s estimates of fair value for its financial assets and financial liabilities are based on the framework established in ASC 820. The framework is based on the inputs used in the valuation process 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. 5. Fair Value Measurements (continued) At December 31, 2019 and 2018 , the Company classified its financial instruments measured at fair value on a recurring basis in the following valuation hierarchy: December 31, 2019 Quoted Prices Significant Significant Fair Value Based on NAV Practical Expedient Total Fair Fixed maturities U.S. treasury bonds $ 95,625 $ — $ — $ — $ 95,625 U.S. agency bonds – mortgage-backed — 538,722 — — 538,722 Non-U.S. government and supranational bonds — 11,999 — — 11,999 Asset-backed securities — 188,170 — — 188,170 Corporate bonds — 996,856 — — 996,856 Municipal bonds — 4,146 — — 4,146 Other investments — — 1,800 3,077 4,877 Total $ 95,625 $ 1,739,893 $ 1,800 $ 3,077 $ 1,840,395 As a percentage of total assets 2.7 % 48.8 % 0.1 % 0.1 % 51.7 % December 31, 2018 Quoted Prices Significant Significant Fair Value Based on NAV Practical Expedient Total Fair Fixed maturities U.S. treasury bonds $ 139,072 $ — $ — $ — $ 139,072 U.S. agency bonds – mortgage-backed — 1,453,134 — — 1,453,134 U.S. agency bonds – other — 129,233 — — 129,233 Non-U.S. government and supranational bonds — 10,072 — — 10,072 Asset-backed securities — 215,082 — — 215,082 Corporate bonds — 1,104,975 — — 1,104,975 Other investments — — 19,883 3,833 23,716 Total $ 139,072 $ 2,912,496 $ 19,883 $ 3,833 $ 3,075,284 As a percentage of total assets 2.6 % 55.1 % 0.4 % 0.1 % 58.2 % 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 approximately 99.7% and 99.9% of our fixed maturities at December 31, 2019 and 2018 , 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 December 31, 2019 and 2018 , approximately 0.3% and 0.1% , respectively, of the Level 2 fixed maturities are valued using the market approach. At December 31, 2019 and 2018 , one security or $5,481 and one security or $5,676 , respectively, 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 December 31, 2019 and 2018 , the Company has not adjusted any pricing provided to it based on the review performed by its investment managers. There were no transfers between Level 1 and Level 2 within the fair value hierarchy. During the year ended December 31, 2019 , the Company transferred its investment in special purpose vehicles focused on lending activities out of Level 3 within the fair value hierarchy due to a change in accounting policy to report these investments at cost less any impairment instead of fair market value. No other transfers to or from Level 3 occurred during the respective periods. 5. Fair Value Measurements (continued) c) Level 3 Financial Instruments At December 31, 2019 , the Company has other investments of $1,800 ( December 31, 2018 - $19,883 ) which includes investments in start-up insurance entities. The fair value of investments in start-up insurance entities was determined using recent private market transactions. Due to significant unobservable inputs in these valuations, the Company classifies the fair value estimate of these other investments as Level 3 within the fair value hierarchy. d) Financial Instruments not measured at Fair Value The following table presents the respective carrying value and fair value for the financial instruments not measured at fair value on the Consolidated Balance Sheets: December 31, 2019 December 31, 2018 Carrying Value Fair Value Carrying Value Fair Value Financial Assets HTM – corporate bonds $ — $ — $ 957,845 $ 940,727 HTM - municipal bonds — — 57,836 57,285 Total financial assets $ — $ — $ 1,015,681 $ 998,012 Financial Liabilities Senior Notes - MHLA – 6.625% $ 110,000 $ 86,460 $ 110,000 $ 75,240 Senior Notes - MHNC – 7.75% 152,500 137,067 152,500 143,960 Total financial liabilities $ 262,500 $ 223,527 $ 262,500 $ 219,200

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Sale of U.S. Treaty Reinsurance operations As described in " Note 1. Organization ", the Company entered into a Renewal Rights transaction with TransRe on August 29, 2018 and subsequently sold Maiden US on December 27, 2018 pursuant to the U.S. Sale Agreement with Enstar U.S. Maiden US was a substantial portion of the Diversified Reinsurance segment, therefore the Company concluded that the sale represented a strategic shift that had a major effect on its ongoing operations and financial results and that all of the held for sale criteria were met. Accordingly, all transactions related to the U.S. treaty reinsurance operations are reported and presented as part of the results from discontinued operations in the Consolidated Statements of Income and any remaining assets and liabilities related to true up of sale consideration are classified as held for sale in the Consolidated Balance Sheet as at December 31, 2018 . As described in " Note 1 — Organization ", 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 retroceded to Cavello on December 27, 2018. Previously, the assets and liabilities related to this business including the retrocession agreement were classified as held for sale, however, a decision has been made to reclassify them as held and used in the current period as it is now considered unlikely that these reserves will be novated in the foreseeable future; therefore, there are no remaining assets and liabilities classified as held for sale as at December 31, 2019 . Furthermore, the assets and liabilities related to this business as at December 31, 2018 have been reclassified from held for sale to conform to the current presentation. The assets and liabilities classified as held for sale in the Consolidated Balance Sheet as at December 31, 2018 comprise: 2018 ASSETS Fixed maturities, available-for-sale, at fair value $ 63,560 Restricted cash and cash equivalents 6,113 Other assets 33,955 Total assets held for sale $ 103,628 LIABILITIES Reserve for loss and loss adjustment expenses $ 6,363 Accrued expenses and other liabilities 78,751 Total liabilities held for sale $ 85,114 The following table summarizes the major classes of items constituting the net loss from discontinued operations presented on the Consolidated Statements of Income for the years ended December 31, 2019 and 2018 : For the Year Ended December 31, 2019 2018 Gross premiums written $ — $ 493,862 Net premiums written $ — $ 479,577 Net premiums earned $ — $ 618,265 Other insurance revenue — — Net investment income — 39,265 Net loss and loss adjustment expenses 6,363 (474,711 ) Commission and other acquisition expenses — (142,946 ) General and administrative expenses (2,392 ) (26,739 ) Amortization of intangible assets — (1,387 ) Income from discontinued operations 3,971 11,747 Loss on disposal of discontinued operations (25,474 ) (113,294 ) Income tax (expense) benefit (1,038 ) 7,434 Loss from discontinued operations, net of income tax $ (22,541 ) $ (94,113 ) As described in "Note 1. Organization", as a result of the Settlement and Commutation Agreement entered into between the Company and Enstar U.S. on July 31, 2019, the Company recorded an additional loss from discontinued operations of $16,714 for the year ended December 31, 2019 , which is included in the net loss from discontinued operations of $22,541 . The loss on disposal of discontinued operations for the year ended December 31, 2018 primarily includes the impairment of goodwill and intangible assets of $74,196 that was recognized due to the sale of Maiden US, net of the payment received for the sale of the Renewal Rights of $7,500 . 6. Discontinued Operations (continued) The goodwill and intangible assets historically were subject to annual impairment testing on October 1 or when “triggering events” occurred or circumstances changed that could have potentially reduced the fair value of a reporting unit below its carrying amount. The sale of the Company's U.S. treaty reinsurance operations resulted in a triggering event and consequently during the year ended December 31, 2018

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Senior Notes At December 31, 2019 and 2018 , both Maiden Holdings and its wholly owned subsidiary, Maiden NA, have outstanding publicly-traded senior notes which were issued in 2016 and 2013, respectively (the "Senior Notes"). The 2013 Senior Notes issued by Maiden NA are fully and unconditionally guaranteed by Maiden Holdings. The Senior Notes are unsecured and unsubordinated obligations of the Company. The following tables detail the issuances outstanding at December 31, 2019 and 2018 : December 31, 2019 2016 Senior Notes 2013 Senior Notes Total Principal amount $ 110,000 $ 152,500 $ 262,500 Less: unamortized issuance costs 3,565 4,027 7,592 Carrying value $ 106,435 $ 148,473 $ 254,908 December 31, 2018 2016 Senior Notes 2013 Senior Notes Total Principal amount $ 110,000 $ 152,500 $ 262,500 Less: unamortized issuance costs 3,610 4,196 7,806 Carrying value $ 106,390 $ 148,304 $ 254,694 Other details: Original debt issuance costs $ 3,715 $ 5,054 Maturity date June 14, 2046 December 1, 2043 Earliest redeemable date (for cash) June 14, 2021 December 1, 2018 Coupon rate 6.625 % 7.75 % Effective interest rate 7.07 % 8.04 % The interest expense incurred on the Senior Notes for the year ended December 31, 2019 was $19,106 ( 2018 - $19,106 ), of which $1,342 was accrued at both December 31, 2019 and 2018 , respectively. The issuance costs related to the Senior Notes were capitalized and are being amortized over the effective life of the Senior Notes. The amortization expense was $214 for the year ended December 31, 2019 ( 2018 - $212 ). Under the terms of the 2013 Senior Notes , the 2013 Senior Notes can be redeemed, in whole or in part after December 1, 2018 at Maiden NA's option at any time and from time to time, until maturity at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued but unpaid interest on the principal amount being redeemed to, but not including, the redemption date. Maiden NA is required to give at least thirty and not more than sixty days notice prior to the redemption date. However, as part of the Company's remediation measures, the Company had previously voluntarily undertaken with the BMA to not voluntarily redeem the 2013 Senior Notes

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. Additionally, Maiden Reinsurance entered into a number of retrocessional quota share agreements with a highly rated global insurer to cede certain lines of business from both of the Company's reportable segments. Effective July 1, 2018, Maiden Reinsurance commuted all of these retrocessional quota share agreements. 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 years ended December 31, 2019 and 2018 was as follows: For the Year Ended December 31, 2019 2018 Premiums written Direct $ 16,637 $ 11,024 Assumed (545,243 ) 2,006,774 Ceded (3,244 ) (3,201 ) Net $ (531,850 ) $ 2,014,597 Premiums earned Direct $ 16,118 $ 10,733 Assumed 434,559 2,032,161 Ceded (2,915 ) (16,692 ) Net $ 447,762 $ 2,026,202 Loss and LAE Gross loss and LAE $ 453,478 $ 1,885,232 Loss and LAE ceded (649 ) (5,111 ) Net $ 452,829 $ 1,880,121 As discussed in " Note 1 — Organization " , on December 27, 2018, 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 retroceded to Cavello in exchange for a ceding commission. The balance of reinsurance recoverable on unpaid losses due from Cavello under this retrocession agreement was $62,699 at December 31, 2019 ( 2018 - $70,158 ). On July 31, 2019, Maiden Reinsurance and Cavello entered into 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 . Please see " Note 1 — Organization " for further details. 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. Reinsurance recoverable on unpaid losses under the retroactive reinsurance agreement was $557,950 while the deferred gain liability was $112,950 as of December 31, 2019 . 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 has provided collateral in the form of a letter of credit in the amount of $445,000 to AmTrust under the LPT/ADC Agreement and is subject to additional collateral funding requirements as explained in " Note 10 — Related Party Transactions " . 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 do not exceed $312,786 . Cavello's parent company, Enstar, has credit ratings of BBB from both Standard &Poor's and Fitch Ratings at December 31, 2019 . The Company's reinsurance recoverable on unpaid losses balance as at December 31, 2019 was $623,422 ( 2018 - $71,901 ) presented in the Consolidated Balance Sheets. At December 31, 2019 and 2018 , the Company had no valuation allowance against reinsurance recoverable on unpaid losses.

Reserve for Loss and Loss Adjus

Reserve for Loss and Loss Adjustment Expenses	12 Months Ended

Insurance [Abstract]
Reserve for Loss and Loss Adjustment Expenses	Reserve for Loss and Loss Adjustment Expenses General 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). The Company in some cases uses underwriting year information to analyze our Diversified Reinsurance segment and subsequently allocate reserves to the respective accident years. The reserve for loss and LAE comprises: December 31, 2019 2018 Reserve for reported loss and LAE $ 1,271,358 $ 1,619,776 Reserve for losses incurred but not reported ("IBNR") 1,168,549 1,506,358 Reserve for loss and LAE $ 2,439,907 $ 3,126,134 The following table represents a reconciliation of the beginning and ending gross and net loss and LAE reserves: For the Year Ended December 31, 2019 2018 Gross loss and LAE reserves, January 1 $ 3,126,134 $ 2,464,442 Less: reinsurance recoverable on unpaid losses, January 1 71,901 24,883 Net loss and LAE reserves, January 1 3,054,233 2,439,559 Net incurred losses related to: Current year 328,194 1,431,484 Prior years 124,635 448,637 452,829 1,880,121 Net paid losses related to: Current year (101,654 ) (440,315 ) Prior years (1,025,381 ) (723,451 ) (1,127,035 ) (1,163,766 ) Retroactive reinsurance adjustment (557,950 ) — Effect of foreign exchange rate movements (5,592 ) (23,961 ) Other adjustments — (77,720 ) Net loss and LAE reserves, December 31 1,816,485 3,054,233 Reinsurance recoverable on unpaid losses, December 31 623,422 71,901 Gross loss and LAE reserves, December 31 $ 2,439,907 $ 3,126,134 Commencing in 2015, Maiden Reinsurance entered into a number of retrocessional quota share agreements with a highly rated global insurer to cede certain lines of business from both of our reportable segments. Effective July 1, 2018, Maiden Reinsurance commuted all of these retrocessional quota share agreements. Actuarial Methods Used to Estimate Loss and LAE Reserves The Company utilizes a variety of standard actuarial methods in its analysis of loss reserves. The selections from these various methods are based on the loss development characteristics of the specific line of business and significant actuarial judgment. The actuarial methods utilized include: The Expected Loss Ratio ("ELR") method is a technique that multiplicatively applies an expected loss ratio to premium earned to yield estimated ultimate losses. The ELR assumption is generally derived from pricing information and historical experience 9. Reserve for Loss and Loss Adjustment Expenses (continued) of the business. This method is frequently used for the purpose of stability in the early valuations of an underwriting year with large and uncertain loss development factors. This technique does not take into account actual loss emergence for the underwriting year being projected. As an underwriting year matures and actual loss experience becomes more credible, other methods may be applied in determining the estimated ultimate losses. The Loss Development ("LD") method is a reserving method in which ultimate losses are estimated by applying a loss development factor to actual reported (or paid) loss experience. This method fully utilizes actual experience. Multiplication of underwriting year actual reported (or paid) losses by its respective development factor produces the estimated ultimate losses. The LD method is based upon the assumption that the relative change in a given underwriting year’s losses from one evaluation point to the next is similar to the relative change in prior underwriting years’ losses at similar evaluation points. In addition, this method is based on the assumption that the reserving and payment patterns as well as the claim handling procedures have not changed substantially over time. In the case where changes to the payment patterns or the claim handling procedures are identified, historical losses are adjusted to the current basis, and development factors are selected based on the relative change of the adjusted losses (the Berquist Sherman method is one example of this approach). When a company has a sufficiently reliable loss development history, a development pattern based on the company’s historical indications may be used to develop losses to ultimate values. The Bornhuetter-Ferguson ("BF") reserving technique is used for long-tailed or lower frequency, more volatile lines. It is also useful in situations where the reported loss experience is relatively immature and/or lacks sufficient credibility for the application of methods that are more heavily reliant on emerged experience. The BF method is an additive IBNR method that combines the ELR and LD techniques by splitting the expected loss into two pieces - expected reported (or paid) losses and expected unreported (or unpaid) losses. Expected unreported (unpaid) losses, estimated by the use of loss development factors, are added to the current actual reported (or paid) losses to produce an estimate of ultimate losses by underwriting year. The BF method introduces an element of stability that moderates the impact of inconsistent changes in paid and reported losses. The average frequency and severity ("FS") reserving technique is used for lines where claim count is available, and the estimate of loss development factors is more difficult due to volatility in historical data. The available data for such lines is usually more volatile in the estimation of future losses using the LD and BF reserving methods. The FS method uses historical data to estimate the average number of ultimate claims (frequency) and the average costs of closed claims (severity). The estimate of ultimate losses by underwriting year is the result of the multiplication of the ultimate number of claims and the average cost of a claim. With the guidance of the methods above, actuarial judgment is applied in the determination of ultimate losses. In general, the Company’s segments have varying levels of seasoning with which the Company has direct experience and as a result, differing methods are utilized to estimate loss and LAE reserves in each segment. In the Diversified Reinsurance segment, the Company utilizes the ELR approach at the onset of reserving an account, the BF method for business with less but maturing loss experience, and as the experience matures the LD method. For proportional or pro-rata business, the Company typically relies heavily on the actual historical contract experience to estimate reserving parameters such as loss development factors, whereas for excess of loss business there will be more usage of industry and/or Company benchmark assumptions. The Company underwrote the AmTrust Reinsurance segment from July 1, 2007 until the Final AmTrust QS Terminations effective January 1, 2019. A large proportion of the exposure in the underlying book of business has significant seasoning, and allows for a significant amount of credibility in using parameters derived from historical experience to calculate reserve estimates. Some segments of the book are a result of recent acquisitions or newer markets for AmTrust. These segments require a greater level of assumptions and professional judgment in deriving ultimate losses, which inherently implies a wider range of reasonable estimates. As a result, the Company has tended to rely on a weighted approach which primarily employs the LD method for aspects of the segment with ample historical data, while also considering the ELR or BF method for exposure resulting from recent acquisitions, or a relative business with a more limited level of experience. The FS method is also considered for segments of the AmTrust book of business for which claim count information is available. The Company’s actuarial analysis of this book of business is more refined in that it utilizes a combination of quarterly and annual data instead of contract period data in totality. Additional data detailing items such as class of business, state, claim counts, frequency and severity is available, further enhancing the reserve analysis. Prior Year Development 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. The following table summarizes the favorable (adverse) prior period development experienced in each of our reportable segments for the years ended December 31, 2019 and 2018 : For the Year Ended Diversified Reinsurance AmTrust Reinsurance Other Total December 31, 2019 $ 1,488 $ (113,722 ) $ (312 ) $ (112,546 ) December 31, 2018 (2,326 ) (399,200 ) (1,685 ) (403,211 ) 9. Reserve for Loss and Loss Adjustment Expenses (continued) During 2019 , the Company increased incurred losses for 2018 and prior accident years by $124,635 or 4.1% of prior year net loss and LAE reserves compared to $448,637 or 18.4% in 2018 . The $112,546 of net adverse development was primarily driven by $113,722 of adverse development in the AmTrust Reinsurance segment combined with net favorable development of $1,488 in the Diversified Reinsurance segment and net adverse development of $312 within the Other category. In addition, some premium for prior accident years is reported to us in subsequent periods. This leads to increases in the provision for loss and LAE in prior years during current periods, which is not considered adverse development. During 2019 , incurred losses in the AmTrust segment increased $21,710 ( 2018 - $45,426 ) associated with $36,739 ( 2018 - $75,359 ) of premiums earned reported during 2019 attributable to 2018 and prior accident years. In the Diversified Reinsurance segment, net favorable prior year loss development was $1,488 for the year ended December 31, 2019 ( 2018 - $2,326 ) primarily due to favorable reserve development in German Auto Programs as well as facultative reinsurance run-off lines. The adverse prior year loss development in 2018 was primarily due to adverse development in the European Capital Solutions business as well as in the facultative reinsurance run-off partially offset by favorable development in International Auto. In the AmTrust Reinsurance segment, net adverse prior year development was $113,722 for the year ended December 31, 2019 ( 2018 - $399,200 ) primarily driven by Commercial Auto Liability of $118,462 and General Liability of $116,746 primarily from accident years 2014 to 2018, partly offset by favorable development in Workers Compensation of $113,003 , gross of the increase in loss from prior year premium recognized during the current period, primarily from accident years 2016 to 2018. The adverse development for the year ended December 31, 2019 includes $9,286 recognized from application of the $40,500 loss corridor cap on AmTrust program business. Please see "Note 10. Related Party Transactions" for further details of the loss corridor. The development in 2018 for the AmTrust Reinsurance segment was largely from Workers' Compensation of $151,269 which represented nearly half of the adverse development, primarily driven by accident years 2014 to 2016, due to a higher expectation of loss development at later maturities as well as adverse development in European Hospital Liability of $95,794 , driven by underwriting years 2011 to 2013, General Liability of $78,317 , driven by accident years 2013 to 2017, and Commercial Auto liability of $76,207 , primarily from accident years 2015 to 2017. The adverse loss development in European Hospital Liability was partly caused by the failure of the Italian government to implement a law passed in April 2017 which was expected to reduce medical malpractice costs, and also by a reduced expectation with regards to the ultimate amount of no-payment claims. Reinsurance recoverable on unpaid losses under the LPT/ADC Agreement with Cavello of $557,950 , which included a deferred gain on retroactive reinsurance of $112,950 , was recognized in the year ended December 31, 2019 in the reconciliation of our beginning and ending gross and net loss and LAE reserves presented above. The deferred gain represents the cumulative adverse development under the AmTrust Quota Share covered under the LPT/ADC Agreement at December 31, 2019 . 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 . Under the Commutation and Release Agreement with AmTrust on July 1, 2019, Maiden Reinsurance transferred cash and invested assets of $312,786 which is the sum of the net ceded reserves of $330,682 with respect to the Commuted Business as of December 31, 2018 less payments of $17,896 made by Maiden Reinsurance with respect to the Commuted Business from January 1, 2019 through July 31, 2019. Settlement of the commutation occurred on August 12, 2019 and is reflected in the reconciliation of our beginning and ending gross and net loss and LAE reserves presented above under net paid losses related to prior years. Our Other category incurred net adverse prior year development of $312 for the year ended December 31, 2019 ( 2018 - $1,685 ) due to increased reserves in the run-off of the NGHC Quota Share which was commuted in November 2019. a) Claims Development The following is a summary of the Company's incurred and paid loss development by accident year, net of reinsurance, from the last nine calendar years including the total reserve for losses, IBNR, plus development on reported loss and LAE for both of our reportable segments, Diversified Reinsurance and AmTrust Reinsurance, as of December 31, 2019 . Information prior to 2019 is included as unaudited supplementary information. Only nine years of information has been presented as it was impractical to obtain the sufficiently detailed additional information on earlier years. The incurred and paid amounts have been translated from the local currency to U.S. dollars using the December 31, 2019 spot rate for all years presented in the table below in order to isolate changes in foreign exchange rates from loss development. Information regarding our Other category has not been presented in the development tables below but is included in the reconciliation, as these losses include amounts from our former NGHC Quota Share segment which was commuted in November 2019. As a reinsurer of primarily quota share contracts, claim counts are available on a very limited basis. Therefore claim counts have not been provided in the tables below as it is impractical to do so. 9. Reserve for Loss and Loss Adjustment Expenses (continued) The Diversified Reinsurance segment incurred and paid losses are analyzed by the following lines of business: (1) International; and (2) European Capital Solutions. The AmTrust Reinsurance segment incurred and paid losses are analyzed by the following lines of business: (1) Workers’ Compensation; (2) Commercial Auto Liability; (3) General Liability; (4) European Hospital Liability; and (5) All Other Lines. There are a number of factors to consider when evaluating the information in these tables: • In the Diversified Reinsurance segment, contracts are written on both an accident year and underwriting year basis, some are multi-line and the majority of the premium is associated with proportional contracts. Many proportional treaty reinsurance contracts are submitted using quarterly bordereau reporting by underwriting year. However, the remaining losses can generally only be allocated to accident years based on estimated premium earning and loss reporting patterns. Further estimates are required to allocate losses to line of business. Multi-line accounts are generally analyzed on an individual basis by line of business, but are booked in the Company’s records to a contract, rather than to each individual line of business within a contract. For the purpose of this disclosure allocations are made to the various lines of business. Management’s assumptions and allocation procedures for these tables may produce results that differ from the actual loss emergence reported by line of business each quarter; • The AmTrust Reinsurance segment consists primarily of two contracts, the European Hospital Liability Quota Share and a much larger quota share that includes all other covered business, the AmTrust Quota Share. There is also a small amount of excess of loss business that has not been written since 2009 which is included as a reconciling item. Maiden receives several cession statements and uses these to report premiums in three categories - Small Business Commercial, Specialty Program and Specialty Risk and Extended Warranty in Note 3. Segment Information . The tables provided include allocations of IBNR reserves to line of business by accident year. Management’s assumptions and allocation procedures for these tables may produce results that differ from the actual loss emergence reported by line of business each quarter; and • For both segments, the premium and exposure for prior accident years is often reported to us in subsequent periods, as reporting lags exist from an insurer to a reinsurer. This leads to increases in the provision for loss and LAE in prior years, but does not reduce expected income (and in many cases can result in additional income). Diversified Reinsurance Segment The following tables represent information on the Company's incurred loss and LAE and cumulative paid loss and LAE, both net of reinsurance, since 2011 for our Diversified Reinsurance segment. The development tables below included reserves acquired from the loss portfolio transfer agreement associated with the GMAC International Insurance Services ("IIS") business as at November 30, 2010 of $98,827 . For the purposes of disclosure, the reserves from the loss portfolio transfer was allocated to the original accident year. Many pro-rata contracts are big enough that specific company development patterns are used. The ELR from the pricing of the account is typically used for the first year or more until the data suggests an alternative result is likely. Use of the ELR method transitions to the BF and then the LD method. For smaller contracts, benchmark development patterns may be used in both the pricing to establish the ELR and the reserving. The use of benchmark patterns is more prevalent in excess of loss business and the movement to experience based methods is slower. Diversified Reinsurance - International The international business written by our IIS team is mainly proportional treaty business, a significant portion of which is Personal Auto quota share but also comprises credit life quota share. Life and personal accident business is also written on a direct basis by Maiden LF. The IIS team works with insurance partners, automobile manufacturers and their related credit providers and other organizations to design and implement insurance programs in both auto distribution-related and other consumer insurance products. For the auto quota share exposure, our initial underwriting year loss projections are generally based on the ELR method, derived from account pricing analyses. Payment and reporting patterns are short-tailed, and the movement away from the ELR to BF or LD methods typically happens very rapidly. Credit life reserves are primarily a function of reporting lag, typically only one or several months on average. The reserves are calculated using a FS methodology, where the frequency is a function of the average claims lag and the average per claims severity. 9.

Reserve for Loss and Loss Adjustment Expenses (continued) Diversified Reinsurance - European Capital Solutions The European Capital Solutions business is mainly a portfolio of assumed reinsurance in Europe which is now in run-off. Maiden Reinsurance began writing treaty reinsurance contracts under this initiative in 2016 therefore only four calendar years of the Company's incurred and paid loss development by accident year have been provided in the tables below. Diversified Reinsurance - European Capital Solutions Incurred loss and LAE, net of reinsurance At December 31, 2019 For the Year Ended December 31, 2016 2017 2018 2019 Total IBNR Accident Year: Unaudited Unaudited Unaudited 2016 $ 4,839 $ 4,911 $ 5,318 $ 5,563 $ 1,052 2017 8,699 10,085 8,997 2,333 2018 22,617 24,490 11,380 2019 15,381 5,487 Total $ 54,431 $ 20,252 Cumulative paid loss and LAE, net of reinsurance For the Year Ended December 31, 2016 2017 2018 2019 Accident Year: Unaudited Unaudited Unaudited 2016 $ 780 $ 2,311 $ 3,271 $ 4,635 2017 1,926 4,070 5,744 2018 3,188 8,321 2019 3,195 Total 21,895 Total net reserves $ 32,536 The following tables represent information on the Company's incurred loss and LAE and cumulative paid loss and LAE, both net of reinsurance, by significant line of business since 2011 for our AmTrust Reinsurance segment. All data shown for the AmTrust in the tables that follow are from the Company’s quota share contracts with AmTrust, both the multi-year AmTrust Quota Share and the annually renewable European Hospital Liability Quota Share. AmTrust purchases significant reinsurance for losses above $10 million covered by the AmTrust Quota Share. The Company’s share of AmTrust’s losses net of reinsurance in the AmTrust Quota Share is generally 40% . Additionally, for the Specialty Program portion of Covered Business only, AmTrust will be 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% . Above and below the defined corridor, Maiden Reinsurance has reinsured losses at its proportional 40% share per 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. Recoverables from the LPT/ADC Agreement are displayed in the column " Impact of ADC " in the tables below. Amounts have been allocated to Accident Year and line of business according to the timing of the respective losses, based on the currently projected payout patterns. These allocations may shift over time as actual payments are made and payout patterns are re–estimated. Please refer to " Note 1 — Organization " for additional information . 9. Reserve for Loss and Loss Adjustment Expenses (continued) AmTrust Reinsurance: Workers’ Compensation This reserve class consists of the Workers’ Compensation portion of the AmTrust Quota Share. The business is written in the U.S. by AmTrust from both their Small Commercial Business and Specialty Program business units. The Small Commercial Business unit focuses on writing smaller, niche workers' compensation exposures in generally low-hazard occupations. Workers’ Compensation business written in the Specialty Program unit is typically part of programs consisting of multiple lines of business. The business is produced by managing general agents with AmTrust regularly adding new programs and terminating or renegotiating unprofitable ones. Our initial underwriting year loss projections are generally based on the ELR method, derived from historical performance after the consideration of loss and premium trends. Since it is proportional exposure, and due to the size and the classes of business insured by AmTrust, this reserving class is much shorter tailed than a traditional workers compensation book, and the transition to the BF and the LD methods happens relatively quickly, within the first several years. 9.

Reserve for Loss and Loss Adjustment Expenses (continued) AmTrust Reinsurance: General Liability This reserve class consists of the General Liability portion of the AmTrust Quota Share. The business is written in the U.S. by AmTrust from both their Small Commercial Business and Specialty Program business units. The Small Commercial Business unit focuses on writing smaller niche business, typically under-served by the broader insurance market, which typically have limits of $1,000 . General Liability business written in the Small Commercial Business unit grew substantially following AmTrust’s renewal rights acquisition in 2014. Specialty Program business may contain a mix of exposures from retail operations, contractors, manufacturers, and other premises. Our initial underwriting year loss projections are generally based on the ELR method, derived from historical performance after the consideration of loss and premium trends. This proportional exposure is medium tailed, and the IBNR is typically derived from the use of the initial ELR for the first several years following the earning of the exposure, followed by a transition to the BF and the LD methods. 9.

AmTrust The following describes transactions 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 AmTrust's Bermuda reinsurance subsidiary, AII, to enter into the AmTrust Quota Share by which AII retrocedes 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 premiums written. On June 11, 2008, Maiden Reinsurance and AII amended the AmTrust Quota Share to add Retail Commercial Package Business to the Covered Business. 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. Please refer to Note 1. "Organization" for additional information . Effective January 1, 2019, Maiden Reinsurance and AII entered into the 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 approximately $647,980 in unearned premium to AII, or approximately $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. Please refer to Note 1. "Organization" for additional information. AII and Maiden Reinsurance also agreed that, as of July 31, 2019, the AmTrust Quota Share shall be deemed amended as applicable so that the Commuted Business is no longer included as part of the 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 a quota share reinsurance contract with AEL and AIU DAC, both wholly owned subsidiaries of AmTrust. Pursuant to the terms of the contract, 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 contract 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. 10. Related Party Transactions (continued) Effective July 1, 2016, the contract 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. Subsequently, 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 Consolidated Results of Operations for the years ended December 31, 2019 and 2018 , respectively: For the Year Ended December 31, 2019 2018 Gross and net premiums written $ (581,001 ) $ 1,886,280 Net premiums earned 364,711 1,928,208 Net loss and loss adjustment expenses (402,679 ) (1,810,667 ) Commission and other acquisition expenses (139,862 ) (622,495 ) Collateral provided to AmTrust a) AmTrust Quota Share In order to provide AmTrust's U.S. insurance subsidiaries with credit for reinsurance on their statutory financial statements, AII, as the direct reinsurer of the AmTrust's insurance subsidiaries, has established trust accounts ("Trust Accounts") for their benefit. Maiden Reinsurance has agreed to provide 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. This collateral may be in the form of (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, (c) a letter of credit obtained by Maiden Reinsurance and delivered to an AmTrust subsidiary on AII's behalf, or (d) premiums withheld by an AmTrust subsidiary at Maiden Reinsurance's request in lieu of remitting such premiums to AII. 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: i. by lending funds of $167,975 at December 31, 2019 and 2018 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. Effective December 18, 2017, interest is payable at a rate equivalent to the Federal Funds Effective Rate ("Fed Funds") plus 200 basis points per annum. Please see " Note 4. (c) Investments" for the total amount of interest earned from this loan. The interest income on the loan was approximately $6,983 for the year ended December 31, 2019 ( 2018 - $6,442 ) and the effective yield was 4.2% ( 2018 - 3.8% ). On January 30, 2019, in connection with the termination of the reinsurance agreements described above, the Company and AmTrust entered into an amendment to the Loan Agreement between Maiden Reinsurance, AmTrust and AII, originally entered into on November 16, 2007, extending the maturity date to January 1, 2025 and acknowledges that due to the termination of the AmTrust Quota Share, no further loans or advances may be made pursuant to the Loan Agreement; ii. 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 December 31, 2019 was approximately $1,155,955 ( 2018 - $3,650,418 ) and the accrued interest was $7,366 ( 2018 - $23,283 ). Please refer to " Note 4. (e) Investments " for additional information. iii. 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 cash and investments of $575,000 to AmTrust as a funds withheld receivable which bears an annual interest rate of 3.5% , subject to annual adjustment. At December 31, 2019 , the balance of funds withheld was $575,000 and the accrued interest was $5,073 . The interest income on the funds withheld receivable was approximately $19,572 for the year ended December 31, 2019 . 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 to AmTrust on behalf of Maiden Reinsurance in an amount representing its obligations under the LPT/ADC Agreement. As 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% . 10. Related Party Transactions (continued) b) European Hospital Liability Quota Share Collateral has been provided to both AEL and AIU DAC under the European Hospital Liability Quota Share agreement: for AEL, the amount of collateral in reinsurance trust accounts at December 31, 2019 was approximately $253,631 ( 2018 - $249,948 ) and the accrued interest was $1,821 ( 2018 - $1,976 ); and for AIUL, in January 2019, Maiden Reinsurance transferred cash of €45,113 ( $51,244 ) to AIU DAC as a funds withheld receivable.

Pursuant to the brokerage agreement, AIIB provided brokerage services relating to the AmTrust Quota Share and the European Hospital Liability Quota Share for a fee equal to 1.25% of the premium assumed. AIIB was not the Company's exclusive broker. The brokerage agreement was terminated as of March 15, 2019 .

Commitments, Contingencies and

Commitments, Contingencies and Concentrations	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Concentrations	Commitments, Contingencies and Concentrations a) Concentrations of Credit Risk At December 31, 2019 and 2018 , the Company’s assets where significant concentrations of credit risk may exist include investments, cash and cash equivalents, loan to related party, reinsurance balances receivable, funds withheld receivable and reinsurance recoverable on unpaid losses. 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 further in " Note 8 — Reinsurance ". The Company manages concentration of credit risk in the 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, funds withheld receivable and its reinsurance balances receivable, within which the largest balances are due from AmTrust. AmTrust has a financial strength/credit rating of A- from A.M. Best at December 31, 2019 . 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 December 31, 2019 will be fully collectible. b) Concentrations of Revenue During the year ended December 31, 2019 , net premiums earned from AmTrust accounted for $364,711 or 81.5% of total net premiums earned ( 2018 – $1,928,208 or 95.2% ). c) Brokers The Company formerly marketed its Diversified Reinsurance segment through third-party intermediaries as well as directly through its own marketing efforts. The majority of business within the Diversified Reinsurance segment was marketed directly through the Company's own efforts therefore reliance on brokers is not of significance for the years ended December 31, 2019 and 2018 . d) Letters of Credit At December 31, 2019 , the Company had letters of credit outstanding of $66,652 ( 2018 - $88,327 ) for collateral purposes which are secured by cash and fixed maturities with a fair value of $86,032 at December 31, 2019 ( 2018 - $111,134 ). e) Employment Agreements The Company has entered into employment agreements with certain individuals. The employment agreements provide for executive benefits and severance payments under certain circumstances. f) Operating Lease Commitments The Company leases office spaces, housing, office equipment and company vehicles under various operating leases expiring in various years through 2022 . The Company did not enter into any new lease arrangements during the year ended December 31, 2019 . The Company's leases are all currently classified as operating leases and none of them have non-lease components. For operating leases that have a lease term of more than twelve months, the Company recognized a lease liability and a right-of-use asset in the 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. The exercise of lease renewal options is at the sole discretion of the Company and none of the current lease renewal options are deemed to be reasonably certain to be exercised. The Company has made an accounting policy election not to include renewal, termination, or purchase options that are not reasonably certain of exercise when determining the effective term of the borrowing. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company's weighted-average remaining lease term is approximately 2.6 years. At December 31, 2019 , the Company's future lease obligations of approximately $2,342 was calculated based on the present value of future annual rental commitments excluding taxes, insurance and other operating costs for non-cancellable operating leases discounted using its secured incremental borrowing rate. This amount has been recognized on the Company's Consolidated Balance Sheets as a lease liability of $2,342 within accrued expenses and other liabilities with an equivalent amount for the right-of-use asset presented as part of other assets. Under the guidance, the Company continues to recognize the related leasing expense on a straight-line basis over the lease term on the Consolidated Statements of Income. The Company's total lease expense for the year ended December 31, 2019 was $1,776 ( 2018 - $2,318 ) which was recognized within net income consistent with the accounting treatment applicable in prior periods under Topic 840 . The operating cash outflows from operating leases included in the measurement of the lease liability during the year ended December 31, 2019 was $1,363 . 11. Commitments, Contingencies and Concentrations (continued) At December 31, 2019 , the scheduled maturity of the Company's operating lease liabilities are expected to be as follows: December 31, 2019 2020 $ 1,172 2021 741 2022 741 Discount for present value (312 ) Total discounted operating lease liabilities $ 2,342 g) Other Commitments The Company has remaining unfunded commitments on its investment in limited partnerships of approximately $340 at December 31, 2019 ( 2018 - $414 ). The Company also has remaining unfunded commitments on its investments in special purpose vehicles focused on lending activities of approximately $767 at December 31, 2019 ( 2018 - $7,359 ). h) Other Collateral In the ordinary course of business, the Company enters into reinsurance agreements that may include terms which could require the Company to collateralize certain of its obligations. i) Deposit Insurance The Company maintains cash and cash equivalents balances at financial institutions in the U.S., Bermuda and other international jurisdictions. In the U.S., the Federal Deposit Insurance Corporation secures accounts up to $250 . In certain other international jurisdictions, there exist similar protections. Management monitors balances in excess of insured limits and believes they do not represent a significant credit risk to the Company. j) 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 arbitrations, 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 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. 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, alleging that Defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 (and Section 20(a) for control person liability) by making misrepresentations about the Company and its business, including the Company’s risk management and underwriting policies and practices. Plaintiffs further claim that these misrepresentations inflated the price of Maiden Holdings' common shares, and that when the truth about the misrepresentations was revealed, the Company’s stock price fell, causing Plaintiffs to incur losses. The Company has not yet been served with an amended complaint, but believes the claims are without merit and intends to vigorously defend itself. There exist and the Company expects additional lawsuits to 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 conditions.

At March 15, 2020 , because preference share dividends have not been declared and paid for six quarterly dividend periods, the holders of the Preference Share Series A, Series C and Series D are collectively entitled to vote for the election of a total of two additional members of the Company's Board of Directors. c) Preference Shares – Series C On November 25, 2015 , the Company issued and authorized a total of 6,600,000 7.125% Preference Shares – Series C (the "Series C"), par value $0.01 per share, at a price of $25 per preference share. The Series C have no stated maturity date and are redeemable in whole or in part at the sole option of the Company any time after December 15, 2020 at a redemption price of $25 per preference share plus any declared and unpaid dividends, without accumulation of any undeclared dividends. Dividends on the Series C are non-cumulative. Consequently, in the event a dividend is not declared on the Series C for any dividend period, holders of Series C will not be entitled to receive a dividend for such period, and such undeclared dividend will not accrue and will not be payable. During any dividend period, so long as any Series C remain outstanding, unless the full dividends for the latest completed dividend period on all outstanding Series C have been declared and paid, no dividend shall be paid or declared on the common shares. The holders of the Series C, together with other preference share series, have no voting rights other than the right to elect up to two directors if preference share dividends are not declared and paid for six or more dividend periods. For the year ended December 31, 2019 , the Company did not declare or pay dividends on the Series C shares ( 2018 - $8,816 or $1.3359 per share). No dividends have been declared by the Company's Board of Directors on the Series C shares since the fourth quarter of 2018. At March 15, 2020 , because preference share dividends have not been declared and paid for six quarterly dividend periods, the holders of the Preference Share Series A, Series C and Series D are collectively entitled to vote for the election of a total of two additional members of the Company's Board of Directors. d) Preference Shares - Series A On August 22, 2012, the Company issued and authorized a total of 6,000,000 8.25% Preference Shares – Series A (the "Series A"), par value $0.01 per share, at a price of $25 per preference share.

Dividends on the Series A are non-cumulative. Consequently, in the event a dividend is not declared on the Series A for any dividend period, holders of Series A will not be entitled to receive a dividend for such period, and such undeclared dividend will not accrue and will not be payable. During any dividend period, so long as any Series A remain outstanding, unless the full dividends for the latest completed dividend period on all outstanding Series A have been declared and paid, no dividend shall be paid or declared on the common shares. The holders of the Series A, together with other preference share series, have no voting rights other than the right to elect up to two directors if preference share dividends are not declared and paid for six or more dividend periods. For the year ended December 31, 2019 , the Company did not declare or pay dividends on the Series A shares ( 2018 - $9,282 or $1.5469 per share).

Share-based Payment Arrangement, Noncash Expense [Abstract]
Share Compensation and Pension Plans	Share Compensation and Pension Plans The Company’s Amended and Restated 2007 Share Incentive Plan ("2007 Plan"), provides for grants of options, restricted shares and restricted share units. New shares are issued upon exercise of options and vesting of restricted shares and share units. The total number of common shares currently reserved for issuance under the Plan is 10,000,000 . The 2007 Plan is administered by the Compensation Committee of the Board of Directors (the "Committee"). Share Options Exercise prices of options are established at or above the fair market value of the Company’s common shares at the date of grant. Under the Plan, unless otherwise determined by the Committee and provided in an award agreement, 25% of the options will become exercisable on the first anniversary of the grant date, with an additional 6.25% of the options vesting each quarter thereafter based on the grantee’s continued employment over a four -year period, and will expire ten years after grant date. The fair value of each option grant is separately estimated for each vesting date. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the award and each vesting date. The Company has estimated the fair value of all share option awards on the date of the grant by applying the Black-Scholes-Merton multiple-option pricing valuation model. The application of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense. The following table shows all options granted, exercised, forfeited and expired under the Plan for the years ended December 31, 2019 and 2018 : Number of Weighted Weighted Average Grant-Date Fair Value Weighted Aggregate Range of Outstanding, December 31, 2017 1,516,769 $ 7.03 2.45 years $ 1,100 $3.28 - $13.98 Granted 275,000 $ 7.07 $ 1.36 $3.24 - $7.20 Exercised (9,500 ) $ 3.28 $ 5,715 Expired (1,038,510 ) $ 6.50 Forfeited (85,935 ) $ 7.23 Outstanding, December 31, 2018 657,824 $ 7.92 4.40 years $ — $3.24 - $13.98 Granted 7,500 $ 1.31 $ 0.25 Expired (119,320 ) $ 5.78 Forfeited (61,875 ) $ 7.15 Outstanding, December 31, 2019 484,129 $ 8.44 3.63 years $ — $1.31 - $13.98 Total exercisable at December 31, 2019 390,379 $ 8.90 2.53 years $ — $3.24 - $13.98 The weighted average grant date fair value was $2.29 ( 2018 - $2.08 ) for all options outstanding at December 31, 2019 . There was $65 ( 2018 - $178 ) of total unrecognized compensation cost related to non-vested options at December 31, 2019 which will be recognized during the next 1.25 years . There were no options exercised during the year ended December 31, 2019 . During the year ended December 31, 2018, cash in the amount of $31 was received from employees as a result of employee share option exercises. In connection with these exercises, there was no tax benefit realized by the Company. Restricted Shares and Restricted Share Units The fair value of each restricted share or restricted share unit is determined based on the market value of the Company's common shares on the date of grant. The total estimated fair value is amortized as an expense on a straight-line basis over the requisite service period as determined by the Committee, which varies between 2 to 3 years for employees and 1 year for directors. Performance-Based Restricted Share Units ("PB-RSU") The Committee approved the formation of a long-term incentive program under the Plan on March 1, 2011. On that date, the Committee determined to award PB-RSU to certain senior leaders of the Company. The formula for determining the amount of PB-RSU awarded uses a combination of a percentage of the employee's base salary (based on a benchmarking analysis from our compensation consultant) divided by the closing price on NASDAQ of our common shares on that date. The grants were performance based which required that certain criteria such as non-GAAP operating return on common equity, underwriting performance, revenue growth and operating expense be met during the performance period to attain a payout. Each metric had a corresponding weighted percentage with a target and maximum level of performance goal set to achieve a payout. All prior PB-RSU were paid 50% based on certain criteria stated above, while the other 50% of the payout was based upon the recommendation of the Company's CEO and the Committee's ultimate discretion of individual contribution to business results and strategic success for the performance period. Settlement of the grants were made in common shares upon the decision of the Committee and the performance cycles were for three years . Beginning in 2014 and ending in 2018 with final payouts in 2019, the Committee approved an annual award of PB-RSU to certain senior leaders of the Company with each annual award vesting over three years . 14. Share Compensation and Pension Plans (continued) Non-Performance-Based Restricted Share Units ("NPB-RSU") Beginning in 2012, the Committee approved an annual award of NPB-RSU with each annual award vesting over three years . The total fair value of share units vested during the year ended December 31, 2019 was $219 ( 2018 - $897 ). Starting in fiscal year 2019, the Company has changed its practice of awarding a fixed number of restricted share units to the non-employee directors and instead intends to grant such directors $65 worth of compensation in the form of either restricted share units, stock options or cash. For 2019, the compensation was granted in the form of cash to each director. It is the Company's intention that annually, on or around June 1, each non-employee director will receive a grant of $65 worth of compensation which, if non-cash compensation, will vest on the first anniversary of the grant. Discretionary Non-Performance-Based Restricted Shares ("NPB-RS") Beginning in 2013, the Committee approved an annual award of NPB-RS with each annual award vesting either over two or three years . The total fair value of restricted shares vested during the year ended December 31, 2019 was $582 ( 2018 - $400 ). The following table shows a summary of activity under the Company's restricted share awards: Non-Performance-Based Restricted Share Units Non-Performance-Based Restricted Shares Performance Based Restricted Share Units (1) Number of Weighted Average Grant-Date Fair Value Number of Weighted Average Grant-Date Fair Value Number of Weighted Average Grant-Date Fair Value Non-vested at December 31, 2017 97,258 $ 12.65 37,226 $ 14.93 810,464 $ 14.60 Awards granted 25,000 $ 8.75 268,971 $ 5.79 734,668 $ 7.20 Awards vested (71,928 ) $ 12.47 (27,726 ) $ 14.43 (99,931 ) $ 13.88 Awards forfeited (25,330 ) $ 13.16 (17,500 ) $ 9.36 (597,556 ) $ 11.15 Non-vested at December 31, 2018 25,000 $ 8.75 260,971 $ 5.94 847,645 $ 10.71 Awards granted — $ — 1,669,490 $ 0.79 — $ — Awards vested (25,000 ) $ 8.75 (91,823 ) $ 6.34 (83,751 ) $ 13.16 Awards forfeited — $ — (19,841 ) $ 1.26 (763,894 ) $ 10.44 Non-vested at December 31, 2019 — $ — 1,818,797 $ 1.24 — $ — (1) For Performance Based Shares, the number of shares is stated at the maximum number that can be attained if the performance conditions are met. Forfeitures represent shares forfeited due to vesting below the maximum attainable as a result of the Company not fully meeting the performance conditions. There was $1,827 of total unrecognized compensation cost related to restricted shares at December 31, 2019 , which will be recognized during the next 1.70 years. Total share-based expense for the year ended December 31, 2019 was $1,911 ( 2018 - $1,276 ). Pension Plans The Company provides pension benefits to eligible employees principally through various defined contribution plans sponsored by the Company which vary by subsidiary. The Company’s expenses for its defined contribution plans for the year ended December 31, 2019 was $774 ( 2018 - $1,543 ). 2019 Omnibus Incentive Plan During the 2019 Annual General Meeting of Shareholders of the Company held on December 10, 2019, the 2007 Plan was terminated and replaced with the 2019 Omnibus Incentive Plan ("2019 Plan"). The Company filed with the Securities and Exchange Commission ("SEC") the Form S-8 "Securities offered to employees pursuant to employee benefit plans" on January 20, 2020, which covers the offer and resale of up to 11,289,956 of the Company's common shares, par value $0.01 per share. Such shares may be offered and sold from time to time by certain officers and directors of the Company who have acquired or will acquire such shares pursuant to the 2019 Plan. See the SEC filing for further details regarding the 2019 Plan.

Statutory Requirements and Divi

Statutory Requirements and Dividend Restrictions	12 Months Ended

Statutory Financial Information [Abstract]
Statutory Requirements and Dividend Restrictions	Statutory Requirements and Dividend Restrictions Our insurance and reinsurance operations are subject to insurance and/or reinsurance laws and regulations in the jurisdictions in which they operate. These regulations include certain liquidity and solvency requirements whereby restrictions are imposed on the amount of dividends or other distributions, such as loans or cash advances, available to shareholders without prior approval of the insurance regulatory authorities. The statutory capital and surplus and statutory net (loss) income of our principal operating subsidiaries in their respective jurisdictions were as follows: Maiden Reinsurance (1) Maiden LF Maiden GF Statutory Capital and Surplus December 31, 2019 $ 921,984 $ 10,234 $ 8,902 December 31, 2018 869,883 7,588 6,182 Statutory Net (Loss) Income For the Year Ended December 31, 2019 $ (103,521 ) $ (785 ) $ 408 For the Year Ended December 31, 2018 (389,373 ) (482 ) 88 (1) Statutory Capital and Surplus and Statutory Net Loss is prior to Maiden Reinsurance's re-domestication to Vermont. a) Bermuda Maiden Reinsurance was registered as a Class 3B reinsurer under The Insurance Act 1978 (Bermuda), amendments thereto and related regulations (the "Insurance Act"). Under the Insurance Act, Maiden Reinsurance was subject to enhanced capital requirements in addition to minimum solvency and liquidity requirements. Maiden Reinsurance was also required to maintain statutory economic capital and surplus at a level at least equal to its Enhanced Capital Requirement ("ECR") which is the greater of its minimum solvency margin ("MSM") and the required capital calculated by reference to the Bermuda Solvency Capital Requirement ("BSCR"). Prior to its re-domestication of Maiden Reinsurance to Vermont, pursuant to Bermuda law, the Company was required to ensure that the value of the group's assets exceeded the amount of the group's liabilities by the aggregate minimum margin of solvency of each qualifying member of the group ("Group MSM"). Since December 31, 2013, the Company has been required to maintain available group capital and surplus at a level equal to or in excess of the Group Enhanced Capital Requirement ("Group ECR") which is established by reference to either the Group Bermuda Solvency Capital Requirement ("Group BSCR") model or an approved group internal capital model. Both the Company and Maiden Reinsurance met and exceeded their respective MSM and ECR ratios as required by Bermuda insurance legislation at December 31, 2019 . Under the Insurance Act, prior to its re-domestication to Vermont, Maiden Reinsurance was prohibited from declaring or paying dividends of more than 25% of its total statutory capital and surplus, as shown in its previous financial year statutory balance sheet, unless at least seven days before payment of the dividend, it files with the BMA an affidavit that it will continue to meet its minimum capital requirements as described above. Maiden Reinsurance was also required to obtain the BMA’s prior approval before reducing its total statutory capital, as shown in its previous financial year statutory balance sheet, by 15% or more. Maiden Reinsurance was also restricted in paying dividends that would result in Maiden Reinsurance failing to comply with the ECR as calculated based on the BSCR or cause it to fail to meet its relevant margins. Finally, prior to its re-domestication to Vermont, Maiden Reinsurance had voluntarily undertaken with the BMA not to make any capital distributions of any kind, including the payment of any common or preference share dividends, without the express consent of the BMA. At December 31, 2019 , the maximum dividend Maiden Reinsurance could pay, without a signed affidavit, having met minimum levels of statutory capital and surplus was $0 ( 2018 - $0 ). No dividends were paid during the years ended December 31, 2019 and 2018 . b) United States of America During the fourth quarter of 2019, our principal operating subsidiary, Maiden Reinsurance, submitted the necessary filings to discontinue its operations from Bermuda and to apply to be licensed and re-domesticate to the State of Vermont in the U.S. Filings were made with the Vermont DFR, Vermont Secretary of State as well as with the BMA to provide notice of the Company's intent to discontinue from Bermuda and re-domesticate to Vermont. Maiden Reinsurance completed the re-domestication on March 16, 2020. We have determined that re-domiciling Maiden Reinsurance to Vermont enables us to better align our operations, capital and resources with our liabilities, which originate mostly in the U.S., resulting in a more efficient structure.The re-domestication, in combination with the Strategic Review previously taken and undertaken in close consultation with the BMA to de-risk the Company’s balance sheet, is expected to continue to strengthen the Company’s capital position and solvency ratios. Under Vermont statutory regulations, no captive insurance company may pay a dividend out of, or other distribution with respect to, capital or surplus without the prior approval of the Commissioner. Approval of an ongoing plan for the payment of dividends or other distributions shall be conditioned upon the retention, at the time of each payment, of capital or surplus in excess of amounts specified by, or determined in accordance with formulas approved by, the Commissioner. Notwithstanding the provisions of 11B Vermont Statutes Annotated chapter 13, a captive insurance may make such distributions as are in conformity with its purposes and approved by the Commissioner. 15. Statutory Requirements and Dividend Restrictions (continued) c) Sweden The Company has two Swedish domiciled insurance subsidiaries in Sweden, Maiden LF and Maiden GF, both regulated by the Swedish Finansinspektionen ("Swedish FSA"). Maiden LF was required to maintain a minimum level of statutory capital and surplus of $5,296 at December 31, 2019 ( 2018 - $4,372 ). This requirement was met by Maiden LF throughout the year. The statutory assets were approximately $16,501 at December 31, 2019 ( 2018 - $13,206 ) and statutory capital and surplus was approximately $10,234 at December 31, 2019 ( 2018 - $7,588 ). Maiden LF is subject to statutory and regulatory restrictions under the Swedish FSA that limit the maximum amount of annual dividends or distributions paid by Maiden LF to Maiden Holdings. As of December 31, 2019 , Maiden LF is allowed to pay dividends or distributions not exceeding $975 ( 2018 - $1,801 ). No dividends were paid during the years ended December 31, 2019 and 2018 . Maiden GF was required to maintain a minimum level of statutory capital and surplus of $2,951 at December 31, 2019 ( 2018 - $2,867 ). This requirement was met by Maiden GF throughout the year. The statutory assets were approximately $10,940 at December 31, 2019 ( 2018 - $7,257 ) and statutory capital and surplus was approximately $8,902 at December 31, 2019 ( 2018 - $6,182 ). Maiden GF is subject to statutory and regulatory restrictions under the Swedish FSA that limit the maximum amount of annual dividends or distributions paid by Maiden GF to Maiden Holdings. As of December 31, 2019 , Maiden GF is allowed to pay dividends or distributions not exceeding $252 ( 2018 - $0 ). No dividends were paid during the years ended December 31, 2019 and 2018 .

Taxation

Taxation	12 Months Ended

Income Tax Disclosure [Abstract]
Taxation	Taxation Under current Bermuda law, Maiden Holdings and Maiden Reinsurance have received an undertaking from the Bermuda government exempting them from all local income, withholding and capital gains taxes until March 31, 2035. At the present time, no such taxes are levied in Bermuda. Maiden Holdings and Maiden Reinsurance believe that they operate in a manner such that they will not be considered to be engaged in a trade or business in the U.S. Accordingly, Maiden Holdings and Maiden Reinsurance have not recorded any provision for U.S. taxation. Our U.S. subsidiaries are subject to federal, state and local corporate income taxes and other taxes applicable to U.S. corporations. The provision for federal income taxes has been determined under the principles of the consolidated tax provisions of the U.S. Internal Revenue Code and Regulations. Should our U.S. subsidiaries pay a dividend outside the U.S. group, withholding taxes will apply. Tax years 2017 and 2018 are subject to examination in the U.S by the Internal Revenue Service. The Company was examined in prior years and those exams were closed without any impact on our operations. The Company has subsidiary operations in various other locations around the world, including Australia, Ireland, Sweden and the United Kingdom, that are subject to relevant taxes in those jurisdictions. These subsidiaries are not under examination but generally remain subject to examination in all applicable jurisdictions for tax years from 2016 through 2019 . Deferred income taxes have not been accrued with respect to certain undistributed earnings of foreign subsidiaries as it is the intention that such earnings will remain reinvested or will not be taxable. If the earnings were to be distributed, as dividends or otherwise, such amounts may be subject to withholding tax in the country of the paying entity. Currently, however, no withholding taxes have been accrued. There were no unrecognized tax benefits at December 31, 2019 and 2018 . Loss before taxes and income tax (benefit) expense for the years ended December 31, 2019 and 2018 are as follows: For the Year Ended December 31, 2019 2018 Loss from continuing operations before income taxes – Domestic (Bermuda) $ (60,583 ) $ (424,667 ) Loss from continuing operations before income taxes – Foreign (U.S. and others) (49,690 ) (25,184 ) Total loss from continuing operations before income taxes $ (110,273 ) $ (449,851 ) Current tax expense – Domestic (Bermuda) $ — $ — Current tax expense – Foreign (U.S. and others) 112 501 Total current tax expense $ 112 $ 501 Deferred tax expense – Domestic (Bermuda) $ — $ — Deferred tax benefit – Foreign (U.S. and others) (1,023 ) (60 ) Total deferred tax benefit $ (1,023 ) $ (60 ) Total income tax (benefit) expense $ (911 ) $ 441 The following table is a reconciliation of the actual income tax rate for the years ended December 31, 2019 and 2018 to the amount computed by applying the effective tax rate of 0.0% under Bermuda law to the Company's loss from continuing operations before income taxes: For the Year Ended December 31, 2019 2018 Loss from continuing operations before income taxes $ (110,273 ) $ (449,851 ) Less: income tax expense (911 ) 441 Net loss from continuing operations $ (109,362 ) $ (450,292 ) Reconciliation of effective tax rate (% of income before income taxes) Bermuda tax rate — % — % U.S. taxes at statutory rates 0.2 % 1.1 % Valuation allowance in respect of U.S. taxes 0.7 % (1.1 )% Other jurisdictions (0.1 )% (0.1 )% Actual tax rate 0.8 % (0.1 )% 16. Taxation (continued) Deferred income taxes reflect the tax impact of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. The significant components of the Company's deferred tax assets and liabilities at December 31, 2019 and 2018 were as follows: December 31, 2019 2018 Deferred tax assets: Net operating losses $ 46,735 $ 44,119 Capital loss carry-forward 6,338 12,345 Interest limitation 2,338 — Others 513 548 Deferred tax assets before valuation allowance 55,924 57,012 Valuation allowance 55,569 56,326 Deferred tax assets, net 355 686 Deferred tax liabilities: Net unrealized gains on investment 96 33 Deferred tax liabilities 96 33 Net deferred tax asset $ 259 $ 653 The net deferred tax asset at December 31, 2019 was $259 ( 2018 - $653 ). A valuation allowance has been established against the net U.S. deferred tax assets which is primarily attributable to net operating losses and capital losses. At this time, the Company believes it is necessary to establish a valuation allowance against the U.S. net deferred tax assets, other than the Alternative Minimum Tax credit, due to insufficient positive evidence regarding the utilization of these losses. During 2019 , the Company recorded a decrease in the valuation allowance of $757 ( 2018 - increase of $16,392 ). At December 31, 2019 , the Company has available net operating loss carry-forwards of approximately $222,547 ( 2018 - $208,853 ) for income tax purposes which expire beginning in 2029. At December 31, 2019 , the Company also has a capital loss carry-forward of $30,183 ( 2018 - $58,785 ) which will expire in 2023.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events 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, to strengthen the collateral provided under the respective agreements 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 will strengthen 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 will strengthen 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.

Accounting Policies [Abstract]
Basis of Reporting and Consolidation	Basis of Reporting and Consolidation — These Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the U.S. ("U.S. GAAP") and include the accounts of Maiden Holdings and all of its subsidiaries. These Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the period and all such adjustments are of a normal recurring nature. All significant intercompany transactions and accounts have been eliminated. 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 loss. As part of the Strategic Review initiated by the Company's Board of Directors in 2018, the Company made the strategic decision to divest its U.S. treaty reinsurance operations through the sale of Maiden US, completed on December 27, 2018, which had a major effect on its ongoing operations and financial results. Accordingly, all of the remaining assets and liabilities related to the true up of sale consideration are classified as held for sale in the Consolidated Balance Sheet as at December 31, 2018 . The operating results of the Company's U.S. treaty reinsurance business for the years ended December 31, 2019 and 2018 have been reclassified and presented as part of discontinued operations in the Consolidated Statements of Income. Except as explicitly described as held for sale or as discontinued operations, and unless otherwise noted, all discussions and amounts presented herein relate to the Company's continuing operations except for net loss, net loss attributable to Maiden and net loss attributable to Maiden common shareholders. Please see “ Note 6 — Discontinued Operations " for additional information related to discontinued operations.
Estimates	Estimates — The preparation of U.S. GAAP Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. The significant estimates include, but are not limited to, reserve for loss and loss adjustment expenses ("loss and LAE") and deferred gain on retroactive reinsurance; recoverability of reinsurance balances receivable, reinsurance recoverable on unpaid losses and deferred commission and other acquisition expenses; valuation of financial instruments and deferred tax assets; and the determination of other-than-temporary impairment ("OTTI") of investments.
Investments	Investments — The Company has historically classified its fixed maturity investments as either available-for-sale ("AFS") or held-to-maturity ("HTM"). The AFS portfolio is reported at fair value and any unrealized gains or losses are reported as a component of accumulated other comprehensive income ("AOCI"). The HTM portfolio at December 31, 2018 included securities for which the Company had the ability and intent to hold to maturity or redemption and was reported at amortized cost. When a security was transferred from AFS to HTM, the fair value at the time of transfer, adjusted for subsequent amortization, became the security's amortized cost. The net unrealized holdings gains of securities transferred from AFS to HTM at the designation date continue to be reported in the carrying value of the HTM securities and is amortized through other comprehensive income over the remaining life of the securities using the effective yield method in a manner consistent with the amortization of any premium or discount. When a security transferred from HTM to AFS, the security’s amortized cost basis carried over to the AFS category for subsequent amortization of the historical premium or discount, comparisons of fair value and amortized cost for determining unrealized holding gains and losses, and required disclosures of amortized cost. The difference between the security’s amortized cost and fair value at the date of transfer into the AFS portfolio is recognized as an unrealized gain or loss and recorded in AOCI. Due to the termination of both AmTrust quota share contracts effective January 1, 2019, the Company no longer believed that it had the positive ability to hold the securities in the HTM portfolio to maturity because this portfolio served as part of the collateral for the AmTrust Reinsurance segment loss reserves. Therefore, the Company reclassified and transferred all HTM securities to the AFS portfolio in the first quarter of 2019. Please see " Note 4 — Investments " for further details. The fair value of fixed maturity investments is generally determined from quotations received from third-party nationally recognized pricing services ("Pricing Service"), or when such prices are not available, by reference to broker or underwriter bid indications. Short-term investments comprise securities due to mature within one year of the date of purchase. The Company held no short-term investments as at December 31, 2019 and 2018 . The Company's other investments comprise of unquoted investments. The Company accounts for its unquoted other investments at fair value in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 944-325, "Financial Services - Insurance - Investments - Other" ("ASC 944-325"). Unquoted other investments are comprised of investments in limited partnerships, which are reported at fair value based on the financial information received from the fund managers and other information available to management with changes in fair value recognized in net income, as well as investments in start-up insurance entities which are reported at fair value using recent private market transactions. Investments made by special purpose vehicles focused on lending activities are carried at cost less impairment, if any. Any indication of impairment is recognized in income when determined. Purchases and sales of investments are recorded on a trade date basis. Realized gains or losses on sales of investments are determined based on the first in first out cost method. Net investment income is recognized when earned and includes accrued interest and dividend income together with amortization of market premiums and discounts using the effective yield method, net of investment management fees. For U.S. government agency mortgage-backed securities ("Agency MBS") and any other holdings for which there is a prepayment risk, prepayment assumptions are evaluated and revised as necessary. Any adjustments required due to the change in effective yields and maturities are recognized on a prospective basis through yield adjustments. 2. Significant Accounting Policies (continued) A security is potentially impaired when its fair value falls below its amortized cost. On a quarterly basis, all potentially impaired securities are reviewed to determine whether the impairment is temporary or OTTI. OTTI assessments are inherently judgmental, especially where securities have experienced severe declines in fair value over a short period. The Company's review process begins with a quantitative analysis to identify securities to be further evaluated for potential classification as OTTI. For all identified securities, further fundamental analysis is performed that considers, but is not limited to, the following quantitative and qualitative factors: historic and implied volatility of the security; length of time and extent to which the fair value has been less than amortized cost; adverse conditions specifically related to the security or to specific conditions in an industry or geographic area; failure, if any, of the issuer of the security to make scheduled payments; and recoveries or additional declines in fair value subsequent to the balance sheet date. The Company recognizes OTTI losses within earnings for its impaired fixed maturity securities (i) for which the Company has the intent to sell the security or (ii) it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery and (iii) for those securities which have a credit loss. In assessing whether a credit loss exists, the Company compares the present value of the cash flows expected to be collected from the security with the amortized cost basis of the security. In instances in which a determination is made that an impairment exists but the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining amortized cost basis, the impairment is separated into (i) the amount of the total impairment related to the credit loss and (ii) the amount of the total impairment related to all other factors. The amount of the total OTTI related to the credit loss is recognized in earnings. The amount of the total OTTI related to all other factors is recognized in other comprehensive income. In periods after the recognition of OTTI on the fixed maturity securities, the Company accounts for such securities as if they had been purchased on the measurement date of the OTTI at an amortized cost basis equal to the previous amortized cost basis less the OTTI recognized in earnings. For fixed maturity securities in which an OTTI loss was recognized in earnings, the difference between the new amortized cost basis and the cash flows expected to be collected will be amortized into net investment income. As the Company's investment portfolio is the largest component of its consolidated assets, any OTTI on fixed maturity securities could be material to the Company's financial condition and results particularly during periods of dislocation in the financial markets.
Fair Value Measurements	Fair Value Measurements — ASC 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 as follows: • Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since 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 severities, 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. 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 a financial instrument to be reclassified between levels. For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these prices in the amounts disclosed in the Level 1 fair value hierarchy. The Company receives the quoted market prices from the Pricing Service which is a third-party nationally recognized provider. 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 fair value hierarchy. The Company challenges any prices for its investments which are considered not to be representative of fair value. If quoted market prices and estimates 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 investment being valued or through consensus pricing of a pricing service. 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 fair value. The Company bases its estimates of fair values for assets on the bid price as it represents the price a third-party market participant would be willing to pay in an orderly transaction.
Cash and Cash Equivalents	Cash and Cash Equivalents — The Company maintains cash accounts in several banks and brokerage institutions. Cash equivalents consist of investments in money market funds and short-term investments with an original maturity of 90 days or less and are stated at cost, which approximates fair value. Restricted cash and cash equivalents are separately reported in the Consolidated Balance Sheets. The Company maintains certain cash and investments in trust accounts used primarily as collateral for unearned premiums and loss and LAE reserves owed to insureds. The Company is required to maintain minimum balances in these restricted accounts based on pre-determined formulas. Please see " Note 4. (e) Investments " for additional details.
Premiums and Related Expenses	Premiums and Related Expenses — For pro-rata contracts and excess-of-loss contracts where no deposit or minimum premium is specified in the contract, premium written is recognized based on estimates of ultimate premiums provided by the ceding companies. Initial estimates of premium written are recognized in the period in which the underlying risks are incepted. Subsequent adjustments, based on reports of actual premium by the ceding companies, or revisions in estimates, are recorded in the period in which they are determined. Reinsurance premiums assumed are generally earned on a pro-rata basis over the terms of the underlying policies or reinsurance contracts. Contracts and policies written on a "losses occurring" basis cover claims that may occur during the term of the contract or policy, which is typically twelve months. Accordingly, the premium is earned evenly over the term. Contracts which are written on a "risks attaching" basis cover claims which attach to the underlying insurance policies written during the terms of such contracts. Premiums earned on such contracts usually extend beyond the original term of the reinsurance contract, typically resulting in recognition of premiums earned over a 24-month period. Reinsurance premiums on specialty risk and extended warranty are earned based on the estimated program coverage period. These estimates are based on the expected distribution of coverage periods by contract at inception, because a single contract may contain multiple coverage period options, and these estimates are revised based on the actual coverage period selected by the original insured. Unearned premiums represent the portion of premiums written which is applicable to the unexpired term of the contract or policy in force. These premiums can be subject to estimates based upon information received from ceding companies and any subsequent differences arising on such estimates are recorded in the period in which they are determined. Assumed and ceded reinsurance contracts that lack a significant transfer of risk are treated as deposits. No deposit contracts are held as at December 31, 2019 and 2018 . Acquisition expenses represent the costs of writing business that vary with, and are primarily related to, the production of that business. Policy and contract acquisition expenses, including assumed commissions, are deferred and recognized as expense as the related premiums are earned. The Company considers anticipated investment income in determining the recoverability of these costs and believes they are fully recoverable. A premium deficiency is recognized if the sum of anticipated losses and loss adjustment expenses, unamortized acquisition expenses less anticipated investment income exceed unearned premiums.
Loss and Loss Adjustment Expenses Incurred	Loss and Loss Adjustment Expenses Incurred — Loss and LAE represent the estimated ultimate net costs of all reported and unreported losses incurred through December 31 of the latest fiscal year. The reserve for loss and LAE is estimated using a statistical analysis of actuarial data and is not discounted for the time value of money. Although considerable variability is inherent in the estimates of reserves for loss and LAE, management believes that the reserve for loss and LAE is adequate based on known information to date. In estimating loss reserves, the Company utilizes a variety of standard actuarial methods. These estimates are continually reviewed and adjusted as necessary as experience develops or new information becomes available. Such adjustments are included and reported in current operations as favorable or unfavorable prior period development.
Reinsurance and Accounting for Retroactive Reinsurance Agreements	Reinsurance — Reinsurance premiums and loss and LAE ceded to other companies are accounted for on a basis consistent with those used in accounting for original policies issued and pursuant to the terms of the reinsurance contracts. The Company records premiums earned and loss and LAE incurred and ceded to other companies as reduction of premium revenue and loss and LAE, respectively. The unexpired portion of reinsurance purchased by the Company (retrocession or reinsurance premiums ceded) is included in other assets and amortized over the contract period in proportion to the amount of insurance protection provided. The ultimate amount of premiums, including adjustments, is recognized as premiums ceded and amortized over the applicable contract period to which they apply. Premiums earned are reported net of reinsurance in the Consolidated Statements of Income. Reinsurance recoverable on unpaid losses relate to the portion of reserves and paid losses and LAE that are ceded to other companies. Reinsurance recoverable on unpaid losses are separately recorded as an asset in the Consolidated Balance Sheets. The Company remains contingently liable for all loss payments in the event of failure to collect from reinsurers. Accounting for Retroactive Reinsurance Agreements - Retroactive reinsurance agreements are reinsurance agreements under which a reinsurer agrees to reimburse the Company as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability which is amortized into income over the settlement period of the ceded reserves once the paid losses have exceeded the minimum retention. The amount of the deferral is recalculated each period based on actual loss payments and updated estimates of ultimate losses. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the retroactive reinsurance agreement is recognized within income immediately.
Debt Obligations and Deferred Debt Issuance Costs	Debt Obligations and Deferred Debt Issuance Costs — Costs incurred in issuing debt are capitalized and amortized over the contractual life of the debt. The amortization of these costs are included in interest and amortization expenses in the Consolidated Statements of Income. The unamortized amount of issuance costs is presented as a deduction from the related principal liability for senior notes in the Consolidated Balance Sheets.
Leases	Leases — The Company's leases are all currently classified as operating leases and none of them have non-lease components. For operating leases that have a lease term of more than twelve months, the Company recognized a lease liability (presented as part of accrued expenses and other liabilities) and a right-of-use asset (presented as part of other assets) in the Company's 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 a weighted-average discount rate of 10% , representing its estimated secured incremental borrowing rate, in calculating the present value of the lease liability. The Company has made an accounting policy election not to include renewal, termination, or purchase options that are not reasonably certain of exercise when determining the term of the borrowing. The Company recognizes the related leasing expense on a straight-line basis over the lease term in the Company's Consolidated Statements of Income.
Goodwill and Intangible Assets	Goodwill and Intangible Assets — A purchase price that is in excess of the fair value of the net assets acquired arising from a business combination is recorded as goodwill and is not amortized. Other intangible assets with a finite life are amortized over the estimated useful life of the asset. Intangible assets with an indefinite useful life are not amortized similar to goodwill. Goodwill and other indefinite life intangible assets were historically tested for impairment on an annual basis or more frequently if events or changes in circumstances indicated that the carrying amount may not be recoverable. Finite life intangible assets were reviewed for indicators of impairment on an annual basis or more frequently if events or changes in circumstances indicated that the carrying amount may not be recoverable, and tested for impairment if appropriate. For purposes of the annual impairment evaluation, goodwill was assigned to the applicable reporting unit of the acquired entities giving rise to the goodwill. The Company had established October 1 as the date for performing the annual impairment tests or when “triggering events” occur or circumstances changed that could have potentially reduced the fair value of a reporting unit below its carrying amount. Goodwill was considered impaired if the carrying amount of the reporting unit exceeded its fair value. If goodwill or other intangible assets were impaired, they were written down to their estimated fair values with a corresponding loss reflected in the Consolidated Statements of Income.
Noncontrolling Interests	Noncontrolling Interests — The Company accounts for noncontrolling interests in subsidiaries in accordance with ASC Topic 810 " Consolidations"
Income Taxes	Income Taxes — The Company accounts for income taxes using ASC Topic 740 " Income Taxes" for subsidiaries operating in taxable jurisdictions. Deferred income taxes reflect the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. A valuation allowance is recorded if it is more likely than not that some or all of a deferred tax asset may not be realized. The Company considers future taxable income and feasible tax planning strategies in assessing the need for a valuation allowance. In the event the Company determines that it will not be able to realize all or part of its deferred income tax assets in the future, an adjustment to the deferred income tax assets would be charged to income in the period in which such determination is made. In addition, if the Company subsequently assesses that the valuation allowance is no longer needed, a benefit would be recorded to income in the period in which such determination is made. U.S. GAAP allows for the recognition of tax benefits of uncertain tax positions only where the position is more likely than not to be sustained assuming examination by tax authorities. A liability is established for any tax benefit claimed in a tax return in excess of this threshold. Income tax related interest and penalties would be included as income tax expense. The Company has not recorded or accrued any interest or penalties during the years ended December 31, 2019 and 2018 .
Share-Based Compensation Expense	Share-Based Compensation Expense — The Company is authorized to issue restricted share awards and units, performance based restricted share units ("PB-RSUs"), share options and other equity-based awards to its employees and directors. The Company recognizes the compensation expense for share options, restricted share and share unit grants, based on the fair value of the award on the date of grant, over the requisite service vesting period. Forfeitures are accounted for when they occur. The estimated fair value of the grant will be amortized ratably over its vesting period as a charge to compensation expense (a component of general and administrative expenses) and an increase to additional paid-in capital in Consolidated Shareholders’ Equity. The estimated fair value of the PB-RSUs is recognized as a charge to compensation expense and an increase to additional paid-in capital in Consolidated Shareholders’ Equity following the satisfaction of certain criteria during the specified performance period. Forfeitures are accounted for if and when they occur.
Earnings Per Share	Earnings Per Share — Basic earnings per share are computed based on the weighted-average number of common shares outstanding and exclude any dilutive effects of options, restricted share units ("RSUs") and PB-RSUs. Dilutive earnings per share are computed using the weighted-average number of common shares outstanding during the period adjusted for the dilutive impact of share options, RSUs and PB-RSUs. 2. Significant Accounting Policies (continued) The two-class method is used to determine earnings per share based on dividends declared on common shares and participating securities (i.e. distributed earnings) and participation rights of participating securities in any undistributed earnings. Each unvested restricted share granted by the Company to certain senior leaders is considered a participating security and the two-class method is used to calculate net income attributable to Maiden common shareholders per common share – basic and diluted. However, any undistributed losses are not allocated to the participating securities.
Treasury Shares	Treasury Shares — Treasury shares include common shares repurchased by the Company and not subsequently cancelled as well as share repurchases from employees, which represent withholdings in respect of tax obligations on the vesting of restricted shares and performance based shares. These shares are recorded at cost and result in a reduction of the total Maiden shareholders’ equity in the Consolidated Balance Sheets.
Foreign Currency Transactions	Foreign Currency Transactions — The functional currency of the Company and many of its subsidiaries is the U.S. dollar. For these companies, monetary assets and liabilities denominated in foreign currencies are translated at year-end exchange rates, with resulting foreign exchange gains and losses recognized in the Consolidated Statements of Income. Revenues and expenses in foreign currencies are converted at average exchange rates during the year. Monetary assets and liabilities include cash and cash equivalents, reinsurance balances receivable, reinsurance recoverable on unpaid losses, funds withheld receivable, reserve for loss and LAE and accrued expenses and other liabilities. Accounts that are classified as non-monetary such as deferred commission and other acquisition expenses and unearned premiums are not revalued.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards Updates Improvements to Non-employee Share-Based Payment Accounting In June 2018, the FASB issued Accounting Standards Update ("ASU") 2018-07 that simplifies the accounting for share-based payments granted to non-employees for goods and services. Under the guidance, payments to non-employees would be aligned with the requirements for share-based payments granted to employees as FASB viewed the awards to both employees and non-employees to be economically similar and thus two different accounting models were not justified. The Company currently measures directors’ share-based payment awards at fair value as at their grant date; therefore the adoption of this standard on January 1, 2019 did not have any impact on the Company’s Consolidated Financial Statements. Codification Improvements In July 2018, the FASB issued ASU 2018-09 which includes clarifications to existing codifications or corrections of unintended application of guidance not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments in this update include items raised for board consideration through the codification's feedback system that met the scope of this project, making the due diligence process necessary. The amendments affect a wide variety of topics in the codification and apply to all reporting entities within the scope of the affected accounting guidance. None of the topics deemed applicable upon adoption of this standard on January 1, 2019 had a material impact on the financial statements. Topic 842, Leases In July 2018, the FASB issued ASU 2018-11 for targeted improvements related to ASU 2016-02 which provide entities with an additional transition method to apply the new leasing standard. Under the new optional transition method, an entity initially applies ASC 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Topic 842 became effective for the Company during the first quarter of 2019 and was applied using a modified retrospective approach by electing the additional transition method permitted by ASU 2018-11. Under the additional transition method, the Company's reporting for the comparative periods presented in its financial statements will be in accordance with the pre-effective date lease accounting requirements under Topic 840. The Company adopted Topic 842 effective on January 1, 2019 , by electing as a package the practical expedients permitted under the transition guidance of Topic 842, and applied consistently to all leases that had commenced before the effective date of adoption. The package of practical expedients allowed the Company to not reassess the following: whether any expired or existing contracts are or contain leases; the lease classification for any expired or existing leases; and initial direct costs for any existing leases. In addition to electing the package of practical expedients, the Company made an accounting policy election to account for non-lease components separately from lease components. Furthermore, the Company made an accounting policy election not to recognize leases with an initial term of twelve months or less in the Company's Consolidated Balance Sheets. The adoption of this standard on January 1, 2019 impacted the Company’s Consolidated Balance Sheets by recognizing a lease liability within accrued expenses and other liabilities of $2,342 with an equivalent amount for the right-of-use asset presented as part of other assets, but the adoption did not have any impact on its results of operations or cash flows. Please refer to "Note 11. Commitments and Contingencies f) Operating Lease Commitments" for further disclosures regarding the impact of the adoption of Topic 842 in 2019 . 2. Significant Accounting Policies (continued) Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued ASU 2017-08 to amend the amortization period for certain purchased callable debt securities held at a premium. U.S. GAAP historically excluded certain callable debt securities from consideration of early repayment of principal even if the holder was certain that the call option would be exercised. As a result, upon the exercise of a call option on a callable debt security held at a premium, the unamortized premium was then recorded as a loss in earnings. The amendments in ASU 2017-08 affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. The amendments shorten the amortization period for certain callable debt securities held at a premium and require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company holds a number of fixed maturities with callable features on its Consolidated Balance Sheets which includes certain securities purchased at a premium that are being amortized over their contractual maturity period. The Company has always handled the amortization of any premiums by amortizing to the earliest effective maturity date (including call dates); therefore, the adoption of this guidance on January 1, 2019 did not have any impact on its Consolidated Financial Statements. Recently Issued Accounting Standards Not Yet Adopted Accounting for Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued 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 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 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 balances receivable and reinsurance recoverable on unpaid losses are its most significant financial assets 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 December 31, 2019 , 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 the 2023 fiscal year. The Company continues to evaluate the impact of this guidance on its results of operations, financial condition and liquidity. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU 2018-13 for changes to the disclosure framework related to Topic 820 which amends the disclosure requirements for fair value measurement. The following disclosure requirements were removed from Topic 820: (i) amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) policy for timing of transfers between levels, and (iii) valuation processes for Level 3 fair value measurements. The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: (i) changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (ii) range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption.

All data shown for the AmTrust in the tables that follow are from the Company’s quota share contracts with AmTrust, both the multi-year AmTrust Quota Share and the annually renewable European Hospital Liability Quota Share. AmTrust purchases significant reinsurance for losses above $10 million covered by the AmTrust Quota Share. The Company’s share of AmTrust’s losses net of reinsurance in the AmTrust Quota Share is generally 40% . Additionally, for the Specialty Program portion of Covered Business only, AmTrust will be 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% . Above and below the defined corridor, Maiden Reinsurance has reinsured losses at its proportional 40% share per 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. Recoverables from the LPT/ADC Agreement are displayed in the column " Impact of ADC " in the tables below. Amounts have been allocated to Accident Year and line of business according to the timing of the respective losses, based on the currently projected payout patterns. These allocations may shift over time as actual payments are made and payout patterns are re–estimated. Please refer to " Note 1 — Organization " for additional information .

The business is written in the U.S. by AmTrust from both their Small Commercial Business and Specialty Program business units. The Small Commercial Business unit focuses on writing smaller, niche workers' compensation exposures in generally low-hazard occupations. Workers’ Compensation business written in the Specialty Program unit is typically part of programs consisting of multiple lines of business. The business is produced by managing general agents with AmTrust regularly adding new programs and terminating or renegotiating unprofitable ones. Our initial underwriting year loss projections are generally based on the ELR method, derived from historical performance after the consideration of loss and premium trends. Since it is proportional exposure, and due to the size and the classes of business insured by AmTrust, this reserving class is much shorter tailed than a traditional workers compensation book, and the transition to the BF and the LD methods happens relatively quickly, within the first several years. The following tables represent information on the Company's incurred loss and LAE and cumulative paid loss and LAE, both net of reinsurance, since 2011 for our Diversified Reinsurance segment. The development tables below included reserves acquired from the loss portfolio transfer agreement associated with the GMAC International Insurance Services ("IIS") business as at November 30, 2010 of $98,827 . For the purposes of disclosure, the reserves from the loss portfolio transfer was allocated to the original accident year. Many pro-rata contracts are big enough that specific company development patterns are used. The ELR from the pricing of the account is typically used for the first year or more until the data suggests an alternative result is likely. Use of the ELR method transitions to the BF and then the LD method. For smaller contracts, benchmark development patterns may be used in both the pricing to establish the ELR and the reserving. The use of benchmark patterns is more prevalent in excess of loss business and the movement to experience based methods is slower. Diversified Reinsurance - International The international business written by our IIS team is mainly proportional treaty business, a significant portion of which is Personal Auto quota share but also comprises credit life quota share. Life and personal accident business is also written on a direct basis by Maiden LF. The IIS team works with insurance partners, automobile manufacturers and their related credit providers and other organizations to design and implement insurance programs in both auto distribution-related and other consumer insurance products. For the auto quota share exposure, our initial underwriting year loss projections are generally based on the ELR method, derived from account pricing analyses. Payment and reporting patterns are short-tailed, and the movement away from the ELR to BF or LD methods typically happens very rapidly. Credit life reserves are primarily a function of reporting lag, typically only one or several months on average. The reserves are calculated using a FS methodology, where the frequency is a function of the average claims lag and the average per claims severity.

The Small Commercial Business unit focuses on writing smaller niche business, typically under-served by the broader insurance market, and policies typically have limits of $1,000 . Auto Liability business written in the Small Commercial Business unit grew substantially following a large renewal rights acquisition completed by AmTrust in 2014. Commercial Auto Liability business written in the Specialty Program unit is typically part of programs consisting of multiple lines of business. Our initial underwriting year loss projections are generally based on the ELR method, derived from historical performance after the consideration of loss and premium trends. This proportional exposure is relatively short tailed, and the transition to the BF and the LD methods happens relatively quickly, within the first several years. AmTrust Reinsurance: European Hospital Liability AmTrust entered this line of business in Italy in 2010 when it believed there were significant opportunities in what had traditionally been an under-performing market. European Hospital Liability policies are written on a claim made basis. Maiden wrote a separate annually renewable contract covering this exposure in 2011 which is not part of the AmTrust Quota Share. Currently, most exposure remains in Italy with a modest amount of exposure to other European nations. The European Hospital Liability Quota Share is a claims made exposure, and in many instances claims are eventually closed with no liability. This phenomena is estimated during the reserving process, and can result in a provision for pure IBNR (reserves for claims which have not yet been reported) which is minimal or negative. This estimate will vary as the exposure matures which could result in changes to the level of reserves. Also, severity for known claims and expenses can increase over time, which requires a provision for IBNR. The net result is a relatively small amount of IBNR. Our initial underwriting year loss projections are generally based on the ELR method, derived from historical performance after the consideration of loss and premium trends. Loss reporting for this line is unique, as a large proportion of claims are initially reserved but eventually closed with no payment, as the insurer is found to have no liability after investigation of the fundamentals of the claim. In addition, the underlying insurance policies we assume are subject to deductibles on both a per claim and aggregate basis. For these reasons, the LD method is not typically employed in the estimate of loss. After the first several years, we utilize a FS methodology; frequency is estimated on a reported claim basis and adjusted for an estimate of the proportion of claims which will close with no payment, while severity is estimated on both a gross and net of deductible basis.
