Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Maiden Holdings, Ltd. and its subsidiaries (the "Company" or "Maiden") and have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP" or "U.S. GAAP") for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. All significant inter-company transactions and accounts have been eliminated. These interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These unaudited Condensed Consolidated Financial Statements, including these notes, should be read in conjunction with the Company's audited Consolidated Financial Statements, and related notes thereto, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014. Certain reclassifications have been made for 2014 to conform to the 2015 presentation and have no impact on net income and total equity previously reported.

- Definition

The entire disclosure for the organization, consolidation and basis of presentation of financial statements disclosure, and significant accounting policies of the reporting entity. May be provided in more than one note to the financial statements, as long as users are provided with an understanding of (1) the significant judgments and assumptions made by an enterprise in determining whether it must consolidate a VIE and/or disclose information about its involvement with a VIE, (2) the nature of restrictions on a consolidated VIE's assets reported by an enterprise in its statement of financial position, including the carrying amounts of such assets, (3) the nature of, and changes in, the risks associated with an enterprise's involvement with the VIE, and (4) how an enterprise's involvement with the VIE affects the enterprise's financial position, financial performance, and cash flows. Describes procedure if disclosures are provided in more than one note to the financial statements.

Significant Accounting Policies	Jun. 30, 2015
Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies There have been no material changes to our significant accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2014. Recently Issued Accounting Standards Not Yet Adopted Simplifying the Presentation of Debt Issuance Costs In April 2015 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03 which changes the presentation of debt issuance costs in financial statements. Under this new guidance, the Company will be required to present such cost in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The amortization of such costs shall be reported as an interest expense. For public business entities, this final guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning December 15, 2015. Early adoption is permitted and the Company will be required to apply this new guidance retrospectively to all prior periods presented. The Company will also be required, in the year of adoption (and in interim periods within that year) to provide certain disclosures about the change in accounting principle, including the nature of and reason for the change, the transition method, a description of the prior-period information that has been retrospectively adjusted and the effect of the change on the financial line items (that is, debt issuance cost asset and the debt liability). The Company is evaluating the impact of this new guidance on its consolidated results of operations and financial condition. Disclosures about Short-Duration Contracts In May 2015 the FASB issued ASU 2015-09 which is aimed at providing users of financial statements with more transparent information about an insurance entity’s initial claim estimates and subsequent adjustments to those estimates, methodologies and judgments in estimating claims, and the timing, frequency and severity of claims particularly related to products such as auto, homeowners or health insurance. The new disclosures are required for short-duration insurance contracts issued by insurers. For public business entities, this guidance will be effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted and should be applied retrospectively by providing comparative disclosures for each period presented. The Company is evaluating the impact of this new guidance on its consolidated results of operations and financial condition. Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) In May 2015, the FASB issued ASU No. 2015-07 which removes the requirement to categorize all investments for which fair value is measured using the net asset value per share practical expedient within the fair value hierarchy. ASU 2015-07 also removes the requirement to make certain disclosures for investments that are eligible to be measured at fair value using the net asset value per share practical expedient, unless the entity has elected to measure the fair value using that practical expedient. 2. Significant Accounting Policies (continued) For public business entities, this guidance will be effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. A reporting entity should apply the amendments retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. Earlier application is permitted. As this guidance is disclosure-related only, the adoption of this guidance is not expected to have a material impact on the Company’s statements of operations and financial position.

Segment Reporting [Abstract]

Segment Reporting

The Company currently has two reportable segments: Diversified Reinsurance and AmTrust Reinsurance. Refer to "Business - Our Reportable Segments" section included under Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2014 for a detailed discussion about these segments.

The Company evaluates segment performance based on segment profit separately from the results of our investment portfolio. Other operating expenses allocated to the segments are called General and Administrative expenses which are allocated on an actual basis except salaries and benefits where management’s judgment is applied. The Company does not allocate general corporate expenses 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, loans, goodwill and intangible assets, restricted cash and cash equivalents and investments, and prepaid reinsurance premiums, reinsurance recoverable on paid losses and funds withheld (which are presented as part of other assets in the unaudited Condensed Consolidated Balance Sheets). All remaining assets are allocated to Corporate.

Fee-generating business is considered part of the underwriting operations of the Company and is reported as "Other insurance revenue" in the unaudited Condensed Consolidated Statements of Income. To the extent that these fees are generated from underlying insurance contracts sold to third parties that are subsequently ceded under quota share reinsurance contracts to Maiden Reinsurance Ltd. ("Maiden Bermuda"), a proportionate share of the fee is offset against the related acquisition expense.

The following tables summarize our reporting segment's underwriting results and the reconciliation of our reportable segments and Other category's underwriting results to our consolidated net income:

Other-Than-Temporary Impairments ("OTTI")

The Company performs quarterly reviews of its investment portfolio in order to determine whether declines in fair value below the amortized cost basis were considered other-than-temporary in accordance with applicable guidance. At June 30, 2015, we have determined that the unrealized losses on fixed maturities were primarily due to widening of credit spreads since their date of purchase. As we do not intend to sell these securities and it is not more likely than not that we will be required to do so until a recovery of fair value to amortized cost, we currently believe it is probable that we will collect all amounts due according to their respective contractual terms. Therefore, we do not consider these fixed maturities to be other-than-temporarily impaired at June 30, 2015. For the three and six months ended June 30, 2015 and 2014, the Company recognized no OTTI, respectively.

The following summarizes the credit ratings of our AFS fixed maturities:

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

(a) Fair Values of Financial Instruments

FASB Accounting Standards Codification ("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 (i.e. the “exit price”) 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: exchange-traded equity securities, U.S. Treasury bonds, and listed derivatives that are actively traded;

•

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; collateralized loan obligations; 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: insurance and reinsurance derivative contracts; and hedge and credit funds with partial transparency.

The availability of observable inputs can vary from financial instrument to financial instrument 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 Level 3. We use prices and inputs that are current as of the measurement date. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified between 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 hierarchy. The Company receives the quoted market prices from a third party nationally recognized pricing service provider ("the Pricing Service"). When quoted market prices are unavailable, the Company utilizes the Pricing Service to determine an estimate of fair value. The fair value estimates are included in the Level 2 hierarchy. The Company will challenge any prices for its investments which are considered not to be representation of fair value. If quoted market prices and an estimate from the Pricing Service are unavailable, the Company produces an estimate of fair value based on dealer quotations for recent activity in positions with the same or similar characteristics to that being valued 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 the fair value. The Company bases its estimates of fair values for assets on the bid price as it represents what a third party market participant would be willing to pay in an orderly transaction.

ASC 825, “Disclosure About Fair Value of Financial Instruments", requires all entities to disclose the fair value of their financial instruments, both assets and liabilities recognized and not recognized in the balance sheet, for which it is practicable to estimate fair value.

The following describes the valuation techniques used by the Company to determine the fair value of financial instruments held at June 30, 2015.

U.S. government and U.S. government agencies — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, 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. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. government agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency bonds are included in the Level 2 fair value hierarchy.

5. Fair Value of Financial Instruments (continued)

Non-U.S. government and supranational bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government and supranational bonds are observable market inputs, the fair values of non-U.S. government and supranational bonds are included in the Level 2 fair value hierarchy.

Commercial mortgage-backed securities ("CMBS") — These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS are observable market inputs, the fair value of the CMBS is included in the Level 2 fair value hierarchy.

Collateralized loan obligation ("CLO") — These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CLO are observable market inputs, the fair value of the CLO is included in the Level 2 fair value hierarchy.

Corporate bonds — Bonds issued by corporations that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The fair values of corporate bonds are priced by the pricing services using the spread above the risk-free yield curve. The spreads are sourced from broker/dealers, trade prices and the new issue market. Where pricing is unavailable from pricing services, we obtain non-binding quotes from broker-dealers. As the significant inputs used to price corporate bonds are observable market inputs, the fair values of corporate bonds are included in the Level 2 fair value hierarchy.

Municipal bonds — Bonds issued by U.S. state and municipality entities or agencies. The fair values of municipal bonds are generally priced by independent pricing services. The pricing services typically use spreads obtained from broker-dealers, trade prices and the new issue market. As the significant inputs used to price the municipal bonds are observable market inputs, municipal bonds are classified within Level 2.

Short-term investments — Primarily commercial paper issued by corporations, all with maturities greater than 90 days and less than one year at the date of purchase. The fair values of these short-term investments are priced by independent pricing services, using market pricing and other observable market inputs for the same or similar securities obtained from a number of industry standard data providers. As the significant inputs used to price the commercial paper securities are observable market inputs, commercial paper securities are classified within Level 2.

Other investments — Includes both quoted and unquoted investments. The fair value of our quoted equity investment is obtained from the Pricing Service, reflecting the closing price quoted for the final trading day of the period and is classified within Level 1. Unquoted other investments comprise investments in limited partnerships and an investment in preference shares of a start-up insurance producer. The fair values of the 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, and as such, the fair values are included in the Level 3 fair value hierarchy. The fair value of the investment in preference shares of a start-up insurance producer was determined using recent private market transactions and as such, the fair value is included in the Level 3 fair value hierarchy.

Reinsurance balance receivable — The carrying values reported in the accompanying condensed consolidated balance sheets for these financial instruments approximate their fair value due to short term nature of the assets.

Loan to related party — The carrying value reported in the accompanying condensed consolidated balance sheets for this financial instrument approximates its fair value.

Senior notes — The amount reported in the accompanying condensed consolidated balance sheets for these financial instruments represents the carrying value of the notes. The fair values are based on quoted prices of identical instruments in inactive markets and as such, are included in the Level 2 hierarchy.

5. Fair Value of Financial Instruments (continued)

(b) Fair Value Hierarchy

The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in ASC 820. The framework is based on the inputs used in valuation and gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the ASC 820 hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions.

We classified our financial instruments measured at fair value on a recurring basis in the following valuation hierarchy:



June 30, 2015	Quoted Prices in Active Markets for Identical Assets (Level 1)			Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)			Total Fair Value

5. Fair Value of Financial Instruments (continued)

The Company utilized a Pricing Service to estimate fair value measurements for approximately 99.7% and 99.9% of its fixed maturities at June 30, 2015 and December 31, 2014, 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 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. At June 30, 2015 and December 31, 2014, 0.3% and 0.1%, respectively, of the fixed maturities are valued using the market approach. At those dates, a total of three securities and one security, respectively, or approximately $11,290 and $5,016, respectively, of Level 2 fixed maturities, were priced using a quotation from a broker and/or custodian as opposed to the Pricing Service due to lack of information available. At June 30, 2015 and December 31, 2014, we have not adjusted any pricing provided to us based on the review performed by our investment managers.

Other investments: The Company utilized a Pricing Service to estimate fair value measurement for the quoted equity investment reflecting the closing price quoted for the final trading day of the period and is included in Level 1. For the unquoted other investments, the Company has $5,906, or 0.2%, of its investment portfolio in limited partnerships where the fair value estimate is determined by the fund manager based on recent filings, operating results, balance sheet stability, growth, other business and market sector fundamentals and an investment of $1,000 in preference shares of a start-up insurance producer, the fair value of which was determined using recent private market transactions. Due to the significant unobservable inputs in these valuations, the Company includes the estimate of the fair value of the unquoted investments as Level 3.

There have not been any transfers between Level 1 and Level 2 during the periods represented by these unaudited Condensed Consolidated Financial Statements.

The Company has determined that its investments in Level 3 securities are not material to its financial position or results of operations.

The following tables present changes in Level 3 for our financial instruments measured at fair value on a recurring basis:

AmTrust Quota Share Reinsurance Agreement Effective July 1, 2007, the Company and AmTrust entered into a master agreement, as amended (the "Master Agreement"), by which they caused Maiden Bermuda, a wholly owned subsidiary of the Company, and AmTrust's Bermuda reinsurance subsidiary, AmTrust International Insurance, Ltd. ("AII"), to enter into a quota share reinsurance agreement (the "Reinsurance Agreement") by which (a) AII retrocedes to Maiden Bermuda an amount equal to 40% of the premium written by subsidiaries of AmTrust, net of the cost of unaffiliated inuring reinsurance (and in the case of AmTrust's U.K. insurance subsidiary, AmTrust Europe Limited ("AEL"), net of commissions) and 40% of losses and (b) AII transferred to Maiden Bermuda 40% of the AmTrust subsidiaries' unearned premiums, effective July 1, 2007, with respect to the current lines of business. The Master Agreement further provided that AII receives a ceding commission of 31% of ceded written premiums. 6. Related Party Transactions (continued) On June 11, 2008, Maiden Bermuda and AII amended the Reinsurance Agreement to add Retail Commercial Package Business to the Covered Business as a consequence of AmTrust's acquisition of Unitrin Business Insurance ("UBI"). Under the amendment, AmTrust's subsidiaries ceded, upon collection, to Maiden Bermuda 100% of $82.2 million of unearned premium (net of inuring reinsurance) from the acquisition of UBI's in-force book of business. Additionally, AmTrust cedes to Maiden Bermuda 40% of net premiums written, effective June 1, 2008. Maiden Bermuda will pay to AmTrust a ceding commission of 34.375% on the unearned premium cession and the Retail Commercial Package Business. On February 9, 2009, Maiden Bermuda and AII amended the Reinsurance Agreement to clarify that (i) AII would offer Maiden Bermuda the opportunity to reinsure Excess Retention Business, which is defined as a policy issued by an AmTrust insurance subsidiary with respect to which the insurance subsidiary's retention is greater than $5,000 and (ii) the deduction for the cost of inuring reinsurance from Affiliate Subject Premium (as defined in the Reinsurance Agreement) retroceded to Maiden Bermuda is net of ceding commission. Effective April 1, 2011, Maiden Bermuda and AII amended the Master Agreement to reduce the commission on all business ceded except Retail Commercial Package Business to 30% until December, 31, 2011. Thereafter the rate shall be 31% subject to an adjustment of 1% to 30% if the proportion of Specialty Risk and Extended Warranty premium ceded is greater than or equal to 42% of the Covered Business (excluding Retail Commercial Package Business). If the proportion of Specialty Risk and Extended Warranty premium ceded is greater than or equal to 38% but less than 42% of the Covered Business (excluding Retail Commercial Package Business), the commission rate shall be reduced by 0.5% to 30.5%. In addition, the collateral arrangements were restated to clarify that balances relating to all AmTrust subsidiaries are subject to collateral requirements. Effective March 7, 2013, Maiden Bermuda and AII amended the Reinsurance Agreement extending the term of the agreement to July 1, 2016, and shall automatically renew for successive three-year periods thereafter. If AII or Maiden Bermuda elects to so terminate the Reinsurance Agreement, it shall give written notice to the other party hereto not less than nine months prior to either July 1, 2016 or the expiration of any successive three-year period. In addition, either party is entitled to terminate on thirty days' notice or less upon the occurrence of certain early termination events, which include a default in payment, insolvency, change in control of AII or Maiden Bermuda, run-off, or a reduction of 50% or more of the shareholders' equity of Maiden Bermuda or the combined shareholders' equity of AII and the AmTrust subsidiaries. The amendment further provides that, effective January 1, 2013, AII will receive a ceding commission of 31% of ceded written premiums with respect to all Covered Business other than retail commercial package business, for which the ceding commission will remain 34.375%. Lastly, with regard to the Specialty Program portion of Covered Business only, AII will be responsible for ultimate net loss otherwise recoverable from Maiden Bermuda to the extent that the loss ratio to Maiden Bermuda, 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 Bermuda will continue to reinsure losses at its proportional 40% share per the Reinsurance Agreement. AmTrust European Hospital Liability Quota Share Agreement ("European Hospital Liability Quota Share") Effective April 1, 2011, Maiden Bermuda, entered into a quota share reinsurance contract with AEL and AmTrust International Underwriters Limited ("AIUL"), both wholly owned subsidiaries of AmTrust.

Other Reinsurance Agreements Effective September 1, 2010, the Company through its indirect wholly owned subsidiary, Maiden Specialty Insurance Company ("Maiden Specialty"), entered into a quota share reinsurance agreement with Technology Insurance Company, Inc. ("Technology"), a subsidiary of AmTrust.

Maiden Specialty's involvement is limited to certain states where Technology was not fully licensed. The agreement also provides that Maiden Specialty receives a ceding commission of 5% of ceded written premiums. The reinsurance agreement had a term of three years and remained continuously in force until terminated in accordance with the contract. 6. Related Party Transactions (continued) The OPL program was terminated on December 31, 2011 on a run-off basis and the NAXS program terminated on October 31, 2012. Maiden Specialty recorded $21 and $45 of ceded premiums and $2 and $3 ceding commission income for the three and six months ended June 30, 2015, respectively, (June 30, 2014 - $50 and $85 of premiums ceded and $2 and $4 of ceding commission income, respectively). Effective September 1, 2010, our indirect wholly owned subsidiary, Maiden Reinsurance North America, Inc. ("Maiden US"), entered into an arrangement whereby a subsidiary of AmTrust fronted a reinsurance agreement in which Maiden US assumed 80% of the gross liabilities produced under the Southern General Agency program with the other 20% being assumed by a third party. This fronting arrangement compensated AmTrust with a 5% commission of ceded written premiums. The agreement was subsequently amended, effective September 1, 2012, whereby the termination date of the agreement was extended until August 31, 2013. This agreement expired on the termination date and is currently in run-off. Pursuant to the latest amendment, Maiden US now receives 100% of the premium and reinsures 100% of the gross liabilities incurred (from the effective date). As this program is currently in run-off, for the three and six months ended June 30, 2015, Maiden US did not record any premiums earned or commission expense, respectively, (June 30, 2014 - $640 and $1,756 of premiums earned and $32 and $88 of commission expense, respectively). Effective April 1, 2012, Maiden US entered into a reinsurance agreement with AmTrust's wholly owned subsidiary, AmTrust North America, Inc. ("AmTrust NA"). Maiden US shall indemnify AmTrust NA, on an excess of loss basis, as a result of losses occurring on AmTrust NA's new and renewal policies relating to the lines of business classified as Automobile Liability by AmTrust NA in its annual statement utilizing the specific underwriting guidelines defined in the reinsurance agreement. AmTrust NA shall retain the first $1,000 of loss, per any one policy or per any one loss occurrence. Maiden US shall be liable for the amount by which AmTrust NA's loss exceeds $1,000, but the liability of Maiden US shall not exceed $1,000 on any one policy and any one loss occurrence. The agreement provides AmTrust NA with fixed ceding commissions on net premiums written varying between 10% to 27.5% depending on the commission rate in the underlying policy. This agreement has a term of one year and automatically renews annually unless terminated pursuant to the terms of the agreement. Under this agreement, for the three and six months ended June 30, 2015, Maiden US recorded approximately $173 and $329 of net premiums earned and $45 and $82 of commission expense, respectively, (June 30, 2014 - $347 and $650 net premiums earned and $79 and $126 commission expense, respectively).

The maximum liability shall not exceed €20 per insured person and any bound agreement shall not exceed 12 months. Notice of termination for this agreement was given on June 4, 2015 and therefore the agreement shall be terminated within 90 days of this notice.

Commitments and Contingencies Disclosure [Abstract]

There are no material changes from the commitments and contingencies previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

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 Bermuda, 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 concerns regarding corporate governance with respect to negotiation of the terms of the Trust Preferred Securities Offering and seeks reinstatement as Chief Operating Officer, General Counsel and Secretary of Maiden Holdings and Maiden Bermuda, 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. The Company filed its brief in opposition to the petition for review on October 19, 2011. 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 we expect it to conclude in 2015. The Company believes that it had ample reason for terminating such employment for good and sufficient legal cause, and the Company believes that the claim is without merit and is vigorously defending this claim.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jun. 30, 2015
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Maiden Holdings, Ltd. and its subsidiaries (the "Company" or "Maiden") and have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP" or "U.S. GAAP") for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. All significant inter-company transactions and accounts have been eliminated. These interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These unaudited Condensed Consolidated Financial Statements, including these notes, should be read in conjunction with the Company's audited Consolidated Financial Statements, and related notes thereto, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014. Certain reclassifications have been made for 2014 to conform to the 2015 presentation and have no impact on net income and total equity previously reported.
Recent Accounting Pronouncements	Recently Issued Accounting Standards Not Yet Adopted Simplifying the Presentation of Debt Issuance Costs In April 2015 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03 which changes the presentation of debt issuance costs in financial statements. Under this new guidance, the Company will be required to present such cost in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The amortization of such costs shall be reported as an interest expense. For public business entities, this final guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning December 15, 2015. Early adoption is permitted and the Company will be required to apply this new guidance retrospectively to all prior periods presented. The Company will also be required, in the year of adoption (and in interim periods within that year) to provide certain disclosures about the change in accounting principle, including the nature of and reason for the change, the transition method, a description of the prior-period information that has been retrospectively adjusted and the effect of the change on the financial line items (that is, debt issuance cost asset and the debt liability). The Company is evaluating the impact of this new guidance on its consolidated results of operations and financial condition. Disclosures about Short-Duration Contracts In May 2015 the FASB issued ASU 2015-09 which is aimed at providing users of financial statements with more transparent information about an insurance entity’s initial claim estimates and subsequent adjustments to those estimates, methodologies and judgments in estimating claims, and the timing, frequency and severity of claims particularly related to products such as auto, homeowners or health insurance. The new disclosures are required for short-duration insurance contracts issued by insurers. For public business entities, this guidance will be effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted and should be applied retrospectively by providing comparative disclosures for each period presented. The Company is evaluating the impact of this new guidance on its consolidated results of operations and financial condition. Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) In May 2015, the FASB issued ASU No. 2015-07 which removes the requirement to categorize all investments for which fair value is measured using the net asset value per share practical expedient within the fair value hierarchy. ASU 2015-07 also removes the requirement to make certain disclosures for investments that are eligible to be measured at fair value using the net asset value per share practical expedient, unless the entity has elected to measure the fair value using that practical expedient. 2. Significant Accounting Policies (continued) For public business entities, this guidance will be effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. A reporting entity should apply the amendments retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. Earlier application is permitted. As this guidance is disclosure-related only, the adoption of this guidance is not expected to have a material impact on the Company’s statements of operations and financial position.

- Definition

Tabular disclosure of liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, by class that are measured at fair value on a recurring and/or nonrecurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
