	Significant Accounting Policies

	Basis of Reporting and Consolidation — These Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The Consolidated Financial Statements 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 in the Consolidated Financial Statements. Certain prior year comparatives have been reclassified to conform to the current year presentation.

	Estimates — The preparation of these Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported 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 differ from those estimates. The significant estimates reflected in the Company’s financial statements include, but are not limited to:


	•	reserve for loss and loss adjustment expenses;


	•	recoverability of deferred commission and other acquisition expenses;


	•	determination of impairment of goodwill and other intangible assets;


	•	valuation of financial instruments; and


	•	determination of other-than-temporary impairment of investments.

	Investments — The Company currently classifies all of its fixed maturity investments as “available-for-sale” and, accordingly, they are carried at estimated fair value. The fair value of fixed maturity securities is generally determined from quotations received from nationally recognized pricing services, 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 accounts for its other investments at fair value in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 944, “Financial Services” (“ASC 944”). Other investments primarily comprise 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. Unrealized gains or losses on other investments are reported as a component of accumulated other comprehensive income.

	2. Significant Accounting Policies (continued)

	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 interest and dividend income together with amortization of market premiums and discounts using the effective yield method and is net of investment management fees and other expenses. For mortgage-backed securities 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.

	Impairments of investment securities results in a charge to operations when a market decline below cost is deemed to be other than temporary. To determine the recovery period of a fixed maturity security, we consider the facts and circumstances surrounding the underlying issuer including, but not limited to, the following:


	•	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.

	When assessing our intent to sell a fixed maturity security or if it is more likely that we will be required to sell a fixed maturity security before recovery of its cost basis, we evaluate facts and circumstances such as, but not limited to, decisions to reposition our security portfolio, sale of securities to meet cash flow needs and sales of securities to capitalize on favorable pricing. In order to determine the amount of the credit loss for a fixed maturity security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The discount rate is the effective interest rate implicit in the underlying fixed maturity security. The effective interest rate is the original yield or the coupon if the fixed maturity security was previously impaired. If an other-than-temporary impairment (“OTTI”) exists and we have the intent to sell the security, we conclude that the entire OTTI is credit-related and the amortized cost for the security is written down to current fair value with a corresponding charge to realized loss on our Consolidated Statements of Income. If we do not intend to sell a fixed maturity security or it is not more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost but the present value of the cash flows expected to be collected is less than the amortized cost of the fixed maturity security (referred to as the credit loss), we conclude that an OTTI has occurred and the amortized cost is written down to the estimated recovery value with a corresponding charge to realized loss on our Consolidated Statements of Income, as this is also deemed the credit portion of the OTTI. The remainder of the decline to fair value is recorded to other comprehensive income (“OCI”), as an unrealized OTTI loss on our Consolidated Balance Sheets, as this is considered a noncredit (i.e. recoverable) impairment.

	Fair Value Measurements — FASB 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 securities, 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: listed derivatives that are not actively traded; U.S. government-sponsored agency securities; non-U.S. government obligations; corporate and municipal bonds; mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”); short-duration high yield fund, and over-the-counter (“OTC”) derivatives (e.g. foreign currency options and forward contracts); 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; hedge and credit funds with partial transparency; and collateralized loan obligation (“CLO”) — equity tranche securities that are traded in less liquid markets.


	2. Significant Accounting Policies (continued)

	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, a nationally recognized pricing service provider (“Pricing Service”). When quoted market prices are unavailable, the Company utilizes a 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 a 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

Cash and Cash Equivalents — The Company maintains its 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. Accordingly, changes in restricted cash and cash equivalents are reported as an investing activity in our Consolidated Statements of Cash Flows. The Company maintains certain cash and investments in trust accounts to be used primarily as collateral for unearned premiums and loss and loss adjustment expenses reserves owed to insureds. The Company is required to maintain minimum balances in these accounts based on pre-determined formulas. See "Note 4. (e) Investments" for additional details.

Premiums and Related Costs — For pro-rata contracts and excess-of-loss contracts where no deposit or minimum premium is specified in the contract, written premium is recognized based on estimates of ultimate premiums provided by the ceding companies. Initial estimates of written premium 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 12 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.

The unearned portion of reinsurance purchased by the Company (retrocession or reinsurance premiums ceded) is reported as prepaid reinsurance premiums 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. Reserves are established for the unexpensed portion of premiums ceded and losses recoverable are recorded as an asset called reinsurance recoverable on unpaid losses. Premiums earned are reported net of reinsurance in the Consolidated Statements of Income.

Assumed and ceded reinsurance contracts that lack a significant transfer of risk are treated as deposits.

Acquisition expenses represent the costs of writing business that vary with, and are primarily related to, the production of insurance and reinsurance business. Policy and contract acquisition expenses, including assumed commissions and other direct operating expenses that are related to successful contracts are deferred and recognized as expense as related premiums are earned.

Only certain costs incurred in the successful acquisition of new and renewal insurance contracts are capitalized. Those costs include incremental direct costs of contract acquisition that result directly from and are essential to the contract transaction and would not have been incurred had the contract transaction not occurred. All other acquisition-related costs, such as costs incurred for soliciting business, administration, and unsuccessful acquisition or renewal efforts are charged to expense as incurred. Administrative costs, including rent, depreciation, occupancy, equipment, and all other general overhead costs are considered indirect costs and are expensed as incurred.

2. Significant Accounting Policies (continued)

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 and anticipated investment income exceed unearned premium.

Loss and Loss Adjustment Expenses Incurred — Loss and loss adjustment expenses (“LAE”) represent the estimated ultimate net costs of all reported and unreported losses incurred through December 31. The reserve for loss and LAE is estimated using individual case-basis valuations and statistical analysis and is not discounted. 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. In estimating reserves, the Company utilizes a variety of standard actuarial methods. The estimates are continually reviewed and adjusted as necessary as experience develops or new information becomes known. Such adjustments are included in current operations.

Capital Assets — Capital assets are recorded at cost. Maintenance and repairs are charged to operations as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets, as follows:


Furniture and fixtures	3 – 7 years
Computer equipment and software	3 years
Vehicles	3 years
Leasehold improvements	Lease term

Debt Obligations and Deferred Debt Issuance Costs — Costs incurred in issuing debt are capitalized and amortized over the life of the debt. The amortization of these costs is included in interest expense in the Consolidated Statements of Income.

Business Combinations, 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. Other intangible assets with an indefinite useful life are not amortized.

Goodwill and other indefinite life intangible assets are tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. Definite life intangible assets are reviewed for indicators of impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable, and tested for impairment if appropriate. For purposes of the annual impairment evaluation, goodwill is assigned to the applicable reporting unit of the acquired entities giving rise to the goodwill.

The Company has established October 1 as the date for performing its annual impairment tests. If goodwill or other intangible assets are impaired, they are written down to their estimated fair values with a corresponding loss reflected in the Company’s Consolidated Statements of Income.

Noncontrolling Interests — The Company accounts for its noncontrolling interests in accordance with FASB ASC Topic 810 “Consolidations”, and presents such noncontrolling shareholders' interest in the equity section of the Company’s Consolidated Balance Sheets. Net income (loss) attributable to noncontrolling interests is presented separately in the Company’s Consolidated Statements of Income.

Income Taxes — The Company accounts for income taxes using FASB ASC Topic 740 “Income Taxes” for its 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 are included as income tax expense.

Share Based Compensation Expense — The Company recognizes the compensation expense for share option, restricted share and share unit grants, based on the fair value of the award on the date of grant, over the vesting period, which is the requisite service period. The fair value of the grant will be amortized ratably over its vesting period as a charge to compensation expense and an increase to additional paid in capital in Shareholders’ Equity.

2. Significant Accounting Policies (continued)

Earnings Per Share — Basic earnings per share are computed based on the weighted-average number of common shares outstanding. 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 using the treasury stock method and the mandatory convertible preference shares using the if-converted method.

Treasury Shares — Treasury shares are common shares repurchased by the Company and not subsequently cancelled. These shares are recorded at cost and result in a reduction of our 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, we translate monetary assets and liabilities denominated in foreign currencies at year-end exchange rates, with the 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 investments, cash and cash equivalents, reinsurance balances receivable, reserve for loss and loss adjustment expenses 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 subsidiaries and divisions, whose functional currency is not the U.S. dollar, are translated at prevailing year-end exchange rates. Revenues and expenses of such foreign entities are translated at average exchange rates during the year. The effects of the translation adjustments for foreign entities are included in accumulated other comprehensive income. The amount of cumulative translation adjustment at December 31, 2013 was $(8,944) (2012 - $(2,535)).

Recently Adopted Accounting Standards Updates

Comprehensive Income - Reporting of amounts reclassified out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued Accounting Standards Update ("ASU") 2013-02, which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The ASU expands the current disclosure guidance by requiring entities to present separately, for each component of other comprehensive income, current period reclassifications out of accumulated other comprehensive income and other amounts of current period other comprehensive income. Entities may present the disaggregation either on the face of the statement where net income is presented or in the notes to the financial statements. The Company has opted to present this disaggregation of the components of other comprehensive income in the notes to the financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. Early adoption of the guidance is permitted and shall be applied prospectively. The adoption of this guidance as of January 1, 2013 did not have any effect on the Company's results of operations, financial position or liquidity.

Balance Sheet Offsetting

In December 2011, the FASB issued new guidance requiring additional disclosures about financial instruments and derivative instruments that are either: (1) offset for balance sheet presentation purposes or (2) subject to an enforceable master netting arrangement or similar arrangement, regardless of whether they are offset for balance sheet presentation purposes. This guidance is effective at January 1, 2013, with retrospective presentation of the new disclosures required. As this new guidance is disclosure-related only and does not amend the existing balance sheet offsetting guidance, the adoption of this guidance did not have any effect on the Company's results of operations, financial position or liquidity.

Qualitative Impairment Test For Indefinite-Lived Intangibles

On July 27, 2012, the FASB issued final guidance adding an optional qualitative assessment for determining whether an indefinite-lived intangible asset is impaired. This ASU 2012-02 is similar to the goodwill guidance which allows companies to perform a qualitative assessment to test goodwill for impairment. This guidance gives companies the option to first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50%) that an indefinite-lived intangible asset is impaired. If a company determines that it is more likely than not that the fair value of such asset exceeds its carrying amount, it would not need to calculate the fair value of the asset in that year. However, if a company concludes otherwise, it must calculate the fair value of the asset, compare that value with its carrying amount and record an impairment charge, if any. To perform a qualitative assessment, a company must identify and evaluate changes in economic, industry and company-specific events and circumstances that could affect the significant inputs used to determine the fair value of an indefinite-lived intangible asset. The guidance became effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company adopted this guidance on January 1, 2013. The adoption of this guidance did not have any effect on the Company's results of operations, financial position or liquidity.

2. Significant Accounting Policies (continued)

Technical Corrections and Improvements

In October 2012, FASB issued ASU 2012-04, Technical Corrections and Improvements. The amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Additionally, the amendments make the Codification easier to understand and the fair value measurement guidance easier to apply by eliminating inconsistencies and providing needed clarifications. Transition guidance is provided for amendments the FASB believes could change practice. The amendments in this ASU that do not have transition guidance are effective upon issuance for both public and nonpublic entities. For public entities, the amendments that are subject to the transition guidance became effective for fiscal periods beginning after December 15, 2012. This guidance did not have any effect on the Company's results of operations, financial position or liquidity.
Recently Issued Accounting Standards Updates Not Yet Adopted
Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity

In March 2013, FASB issued ASU 2013-05 with the objective of resolving the diversity about whether ASC 810-10, Consolidation - Overall, or ASC 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity.

Under this guidance, when a reporting entity that is also the parent entity, ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity, the parent is required to apply the guidance in ASC 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Additionally, for an equity method investment that is a foreign entity, the partial sale guidance in ASC 830-30-40 continues to be applicable. As such, a pro rata portion of the cumulative translation adjustment should be released into net income upon a partial sale of such an equity method investment. However, this treatment does not apply to an equity method investment that is not a foreign entity. In those instances, the cumulative translation adjustment is released into net income only if the partial sale represents a complete or substantially complete liquidation of the foreign entity that contains the equity method investment.

Furthermore, the amendments in this ASU clarify that the sale of an investment in a foreign entity includes both: (1) events that result in the loss of a controlling financial interest in a foreign entity (that is, irrespective of any retained investment); and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date (sometimes also referred to as a step acquisition). Accordingly, the cumulative translation adjustment should be released into net income upon the occurrence of those events.

The amendments in this ASU are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The amendments should be applied prospectively to derecognition events occurring after the effective date. Prior periods should not be adjusted. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company's results of operations, financial condition or liquidity.

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists

On July 18, 2013, FASB issued ASU 2013-11 which provides guidance on the presentation of an unrecognized tax benefit when a net operating loss ("NOL") carry-forward, a similar tax loss, or a tax credit carry-forward exists. Under this ASU, an entity must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a NOL carry-forward, similar tax loss, or a tax credit carry-forward. There are two exceptions to this form of presentation as follows:


•	To the extent a NOL carry-forward, a similar tax loss, or a tax credit carry-forward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position; and


•	The entity does not intend to use the deferred tax asset for this purpose.

2. Significant Accounting Policies (continued)

If either of these conditions exists, an entity should present an unrecognized benefit in the financial statements as a liability and should not net the unrecognizable tax benefit with a deferred tax asset.

The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company's results of operations, financial condition or liquidity.

	Segment Information

	The Company currently operates three business segments, Diversified Reinsurance, AmTrust Quota Share Reinsurance and the NGHC Quota Share (formerly known as the ACAC Quota Share), which is currently in run-off. The Company evaluates segment performance based on segment profit separately from the results of our investment portfolio. Other operating expenses are called general and administrative expenses and 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 segment, the Company identifies those assets that are attributable to a particular segment such as reinsurance balances receivable, prepaid reinsurance premiums, reinsurance recoverable on unpaid losses, deferred commission and other acquisition expenses, loans, goodwill and intangible assets, other assets and restricted cash and cash equivalents and investments. All remaining assets are allocated to Corporate.

	Fee-generating business, which is included in the Diversified Reinsurance segment, is considered part of the underwriting operations of the Company. To the extent that the fees are generated on underlying insurance contracts sold to third parties that are then ceded under quota share reinsurance contracts with Maiden Bermuda, a proportionate share of the fee is offset against the related acquisition expense. To the extent that fee business is not directly associated with premium revenue generated under the applicable reinsurance contracts, that fee revenue is separately reported on the line captioned “Other insurance revenue” in the Company's Consolidated Statements of Income.

OTTI

We review our investment portfolio for impairment on a quarterly basis. Impairment of investments results in a charge to operations when a fair value decline below cost is deemed to be other-than-temporary. As of December 31, 2013, we reviewed our portfolio to evaluate the necessity of recording impairment losses for other-than-temporary declines in the fair value of investments. During the years ended December 31, 2013, 2012 and 2011, the Company recognized no OTTI. Based on our qualitative and quantitative OTTI review of each asset class within our fixed maturity portfolio, the unrealized losses on fixed maturities at December 31, 2013 were primarily due to widening of credit spreads since their date of purchase. Because we do not intend to sell these securities and it is not more likely than not that we will be required to sell these securities 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 December 31, 2013.

We are required to maintain assets on deposit to support our reinsurance operations and to serve as collateral for our reinsurance liabilities under various reinsurance agreements. The assets on deposit are available to settle reinsurance liabilities. We also utilize trust accounts to collateralize business with our reinsurance counterparties. These trust accounts generally take the place of letter of credit requirements.

	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 as of December 31, 2013.

	U.S. government and U.S. government agencies — Comprised primarily of 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 securities 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 securities 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.

	Non-U.S. government bonds — Comprised of bonds issued by non-U.S. governments and their agencies along with supranational organizations. These securities are generally priced by pricing services. The pricing services 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 bonds are observable market inputs, the fair values of non-U.S. government bonds are included in the Level 2 fair value hierarchy.

	Other mortgage-backed securities — Other mortgage-backed bonds consist of three 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.

	Corporate bonds — Comprised of bonds issued by corporations that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by pricing services. The fair values of corporate bonds that are short-term are priced, by the pricing services, using the spread above the London Interbank Offering Rate ("LIBOR") yield curve and the fair value of corporate bonds that are long-term are priced 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.

	5. Fair Value Measurements (continued)

	Municipal bonds - auction rate — Comprised of auction rate securities issued by U.S. state and municipality entities or agencies. Municipal auction rate securities are reported in the Consolidated Balance Sheets at fair value which approximates their cost. As the significant inputs used to price the auction rate securities are observable market inputs, auction rate securities are classified within Level 2.

	Municipal bonds - other — Comprised of bonds issued by U.S. state and municipality entities or agencies. The fair values of municipal bonds are generally priced by 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.

	Other investments — 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, 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 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 balance sheets for this financial instrument approximates its fair value.

	Senior notes — The amount reported in the accompanying 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.

	Junior subordinated debt — The amount reported in the accompanying balance sheets for this financial instrument represents the carrying value of the debt. The fair value of the debt was derived using the Black-Derman-Toy model. As the fair value of the junior subordinated debt is determined using observable market inputs in the Black-Derman-Toy model, the fair value is included in the Level 2 fair value hierarchy. See "Note 17. Subsequent Events" for additional information related to the redemption of the Junior Subordinated Debt.

	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.

	In accordance with ASC 820, the Company determines fair value of the financial instrument based on the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

	5. Fair Value Measurements (continued)

	At December 31, 2013 and 2012, we classified our financial instruments measured at fair value on a recurring basis in the following valuation hierarchy:

The Company utilized a Pricing Service to estimate fair value measurements for approximately 95.3% and 99.7% of its fixed maturities at December 31, 2013 and 2012, 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 securities 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. As of December 31, 2013 and 2012, 4.7% and 0.3%, respectively, of its fixed maturities are valued using the market approach. At those dates, a total of five securities and one security, respectively, or approximately $150,298 and $26,121, respectively, of Level 2 fixed maturities, were priced using a quotation from a broker and/or custodian as opposed to the Pricing Service. For each of these securities, the Pricing Service was not able to value these newly-issued U.S. agency bonds due to the lack of information available as of December 31, 2013 and 2012. All of these securities were valued subsequently in January 2014 and 2013, respectively, by the Pricing Service. At December 31, 2013 and 2012, we have not adjusted any pricing provided to us based on the review performed by our investment managers.

5. Fair Value Measurements (continued)

There have not been any transfers between Level 1 and Level 2, or Level 2 and Level 3, respectively, during the periods represented by these Consolidated Financial Statements.

Other investments: The Company has $4,092 or approximately 0.1% 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 and other business and market sector fundamentals. Due to the significant unobservable inputs in these valuations, the Company includes the estimate in the amount disclosed as Level 3. The Company also has an investment of $1,000 in preference shares of a start-up insurance producer, the fair value was determined using recent private market transactions, and as such, the fair value is included in the Level 3 fair value hierarchy.

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

c) Level 3 Financial Instruments

The following table presents changes in Level 3 for our financial instruments measured at fair value on a recurring basis for the years ended December 31, 2013 and 2012:

	Goodwill and Intangible Assets

	Goodwill

	Goodwill is calculated as the excess of purchase price over the net fair value of assets acquired. The Company performs an annual impairment analysis to identify potential goodwill impairment and measures the amount of a goodwill impairment loss to be recognized. This annual test is performed during the fourth quarter of each year or more frequently if events or circumstances change in a way that requires the Company to perform the impairment analysis on an interim basis. Goodwill impairment testing requires an evaluation of the estimated fair value of each reporting unit to its carrying value, including the goodwill. An impairment charge is recorded if the estimated fair value is less than the carrying amount of the reporting unit. No impairments have been identified to date.

	Intangible Assets

	Intangible assets consist of finite and indefinite life assets. Finite life intangible assets include customer and producer relationships and trademarks. Insurance company licenses are considered indefinite life intangible assets subject to annual impairment testing.

	The following tables show the analysis of goodwill and intangible assets:


			Goodwill		Intangible Assets			Total

	The goodwill and intangible assets were recognized as a result of the the acquisition of the reinsurance operations of GMAC Insurance (“GMACI”), including its book of assumed reinsurance business, GMAC RE Insurance Services LLC (renamed Maiden Re), GMAC Direct Insurance Company (renamed Maiden US) and Integon Specialty Insurance Company (renamed Maiden Specialty Insurance Company ("Maiden Specialty") (collectively referred to as the “GMAC Acquisition”) on October 31, 2008 and the acquisition of the majority of the reinsurance-related infrastructure, assets and liabilities of U.K. based GMAC International Insurance Services ("IIS") (the "IIS Acquisition") on November 30, 2010 and. The goodwill and intangible assets are assigned to the Diversified Reinsurance segment and are subject to annual impairment testing. No impairment was recorded during the years ended December 31, 2013, 2012 and 2011.

	Senior Notes

	In June 2011, the Company, through its wholly owned subsidiary Maiden Holdings North America, Ltd. ("Maiden NA"), issued $107,500 principal amount of 8.25% Senior Notes (“2011 Senior Notes”) due on June 15, 2041, which are fully and unconditionally guaranteed by the Company. The 2011 Senior Notes are redeemable for cash, in whole or in part, on or after June 15, 2016, at 100% of the principal amount plus accrued and unpaid interest to but excluding the redemption date. The 2011 Senior Notes are an unsecured and unsubordinated obligation of the Company and rank ahead of the Junior Subordinated Debt, described below. The effective interest rate of the 2011 Senior Notes, based on the net proceeds received, was 8.47%. The net proceeds from the sale of the 2011 Senior Notes were $104,689, after issuance costs of $2,811. The issuance costs related to the 2011 Senior Notes were capitalized and are being amortized over the life of the notes. Amortization expense for the year ended December 31, 2013 was $94 (2012 - $94 and for the period from June 15, 2011 to December 31, 2011- $49).

	The interest on the 2011 Senior Notes is payable each quarter beginning on September 15, 2011. Interest expense for the year ended December 31, 2013 was $8,869 (2012 - $8,869 and for the period from June 15, 2011 to December 31, 2011- $4,607), of which $394 was accrued as of December 31, 2013 and 2012, respectively. See "Note 10. Related Party Transactions" for additional information on related party participation in the 2011 Senior Notes.

	In March 2012, the Company, through Maiden NA, issued $100,000 principal amount of 8.00% Senior Notes ("2012 Senior Notes") due on March 27, 2042, which are fully and unconditionally guaranteed by the Company. The 2012 Senior Notes are redeemable for cash, in whole or in part, on or after March 27, 2017, at 100% of the principal amount to be redeemed plus accrued and unpaid interest up to but excluding the redemption date. The 2012 Senior Notes are an unsecured and unsubordinated obligation of the Company and rank ahead of the Junior Subordinated Debt, described below. The effective interest rate of the 2012 Senior Notes, based on the net proceeds received, was 8.28%. The net proceeds from the sale of the 2012 Senior Notes were $96,594, after issuance costs of $3,406. The issuance costs related to the 2012 Senior Notes were capitalized and will be amortized over the life of the notes. Amortization expense for the year ended December 31, 2013 was $113 (for the period from March 27, 2012 to December 31, 2012 - $87).

	The interest on the 2012 Senior Notes is payable each quarter beginning on June 27, 2012. Interest expense for the year ended December 31, 2013 was $8,000 (for the period from March 27, 2012 to December 31, 2012 - $6,111), of which $111 was accrued as of December 31, 2013 and 2012, respectively.

	On November 25, 2013, the Company, through Maiden NA, issued $152,500 principal amount of 7.75% Senior Notes ("2013 Senior Notes") due on December 1, 2043, which are fully and unconditionally guaranteed by the Company. The 2013 Senior Notes are redeemable for cash, in whole or in part, on or after December 1, 2018 at 100% of the principal amount to be redeemed plus accrued and unpaid interest up to but excluding the redemption date. The 2013 Senior Notes are an unsecured and unsubordinated obligation of the Company and rank ahead of the Junior Subordinated Debt, described below. The effective interest rate of the 2013 Senior Notes, based on the net proceeds received, was 8.02%. The net proceeds from the sale of the 2013 Senior Notes were $147,446 after issuance costs of $5,054. The issuance costs related to the 2013 Senior Notes were capitalized and will be amortized over the life of the notes. Amortization expense for the period from November 25, 2013 to December 31, 2013 was $17.

	The interest on the 2013 Senior Notes is payable each quarter beginning on March 1, 2014 and will include accrued interest from November 25, 2013. Interest expense for the period from November 25, 2013 to December 31, 2013 was $1,215, all of which was accrued as of December 31, 2013.

	Junior Subordinated Debt

	On January 20, 2009, the Company completed a private placement of 260,000 units (the “Units”), each Unit consisting of $1,000 principal amount of capital securities (the “Trust Preferred Securities”) of Maiden Capital Financing Trust (the “Trust”), a special purpose trust established by Maiden NA, and 45 common shares, $0.01 par value, of the Company for a purchase price of $1,000.45 per Unit (the “TRUPS Offering”). In the aggregate, 11,700,000 common shares were issued to the purchasers in the TRUPS Offering. This resulted in gross proceeds to the Company of $260,117, before $4,342 of issuance costs.

	7. Long-Term Debt (continued)

	Certain trusts established by Michael Karfunkel and George Karfunkel, two of the Company's Founding Shareholders, purchased an aggregate of 159,000 of the Units, or 61.12%. The remaining 101,000 Units were purchased by existing institutional shareholders of the Company.

	The Trust used the proceeds from the sale of the Trust Preferred Securities to purchase a subordinated debenture (the “Junior Subordinated Debt”) in the principal amount of $260,000 issued by Maiden NA.

	Under the terms of the Trust Preferred Securities, the Company can repay the principal balance in full or in part at any time. However, if the Company repays such principal within five years of the date of issuance, it is required to pay an additional amount equal to one full year of interest on the amount of Trust Preferred Securities repaid. If the remaining amount of the Trust Preferred Securities were repaid within five years of the date of issuance (adjusted for the $107,500 repurchase of Junior Subordinated Debt, which occurred on July 15, 2011), the additional amount due would be $21,350, which would be a reduction in earnings.

	Pursuant to separate Guarantee Agreements dated as of January 20, 2009 with Wilmington Trust Company, as guarantee trustee, each of the Company and Maiden NA has agreed to guarantee the payment of distributions and payments on liquidation or redemption of the Trust Preferred Securities.

	As a consequence of the issuance of a majority of the Units to a related party under ASC Topic 810 “Consolidation”, the Trust is a variable interest entity and the Company is deemed not to be the primary beneficiary of the Trust, therefore it is not consolidated. The issuance of common shares associated with the Trust Preferred Securities resulted in an original issuance discount of $44,928 based on market price of $3.85 on January 20, 2009. The discount is amortized over 30 years based on the effective interest method. The Junior Subordinated Debt and Trust Preferred Securities mature in 2039 and carry a stated or coupon rate of 14% with an effective interest rate of 16.95%.

	Using the proceeds from the 2011 Senior Notes offering and existing cash, the Company repurchased principal amount of $107,500 of the Junior Subordinated Debt on July 15, 2011. Pursuant to the terms of the TRUPS Offering, the Company incurred and paid a repurchase expense equivalent to one year's interest expense of $15,050. The Company also accelerated the amortization of the issuance cost and discount related to the repurchased Junior Subordinated Debt which amounted to $20,313.

	As of December 31, 2013, the stated value of the Junior Subordinated Debt was $126,381, which comprises the principal amount of $152,500 and unamortized discount of $26,119. Amortization expense for the year ended December 31, 2013 was $64 (2012 - $54, 2011 - $46). Interest expense for the year ended December 31, 2013 was $21,350 (2012 - $21,350, 2011 - $29,502), of which $4,448 was accrued as of December 31, 2013 and 2012, respectively. See "Note 17. Subsequent Events" for additional information related to the redemption of the Junior Subordinated Debt.

	Reinsurance

	The Company utilizes reinsurance and retrocessional reinsurance (“ceded reinsurance”) agreements to reduce its exposure to large claims and catastrophic loss occurrences with various reinsurance companies. These agreements provide for recovery from reinsurers of a portion of losses and LAE under certain circumstances without relieving the Company of its obligations to the policyholders. The Company remains liable to the extent that any reinsurance company fails to meet its obligations. Losses and LAE incurred and premiums earned are reported after deduction for reinsurance. In the event that one or more of the reinsurers are unable to meet their obligations under these reinsurance agreements, the Company would not realize the full value of the reinsurance recoverable balances.

	8. Reinsurance (continued)

	The effect of retrocessional activity on net premiums written and earned and on net loss and loss adjustment expenses for the years ended December 31, 2013, 2012 and 2011 was as follows:


	For the Year Ended December 31,	2013			2012			2011

	Net	$	1,349,630		$	1,262,348		$	1,043,054


	The reinsurers with the three largest balances accounted for 38.0%, 13.3% and 11.7%, respectively, of the Company's reinsurance recoverable on unpaid losses balance at December 31, 2013 (2012 – 30.2%, 18.0% and 11.4%, respectively). At December 31, 2013, 90.2% of the reinsurance recoverable on unpaid loss and loss adjusted expenses ceded was due from reinsurers with credit ratings from A.M Best of A or better, 7.5% due from reinsurers with credit ratings of A- and the remaining 2.0% of the reinsurance recoverable was due from reinsurers with credit ratings of B++. At December 31, 2013 and 2012, the Company had no valuation allowance against reinsurance recoverable on unpaid losses.

	Management believes that its use of both historical experience and industry-wide loss development factors provide a reasonable basis for estimating future losses. As the Company writes more business and develops more credible data, the Company expects to assign more weight to its own historical experience than industry-wide results. In either case, future events beyond the control of management, such as changes in law, judicial interpretations of law, and inflation 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 losses and LAE. While anticipated changes in claim costs due to inflation are considered in estimating the ultimate claim costs, changes in average severity of claims are caused by a number of factors that vary with the individual type of policy written. Future average severities are projected based on historical trends adjusted for implemented changes in underwriting standards, policy provisions, and general economic trends. Those anticipated trends are monitored based on actual development and are modified if necessary.

	During 2013, the Company recorded estimated favorable development on prior year loss reserves of $1,413 compared to net adverse development of $23,332 in the prior year and $14,199 in 2011. Included in the total is $13,721 (2012 - $9,134, 2011 - $28,898) of gains relating to the loss portfolio transfers acquired as part of the GMAC Acquisition and the IIS Acquisition. The total gain to date from the loss portfolio transfer reserves is $89,373 (2012 - $75,656, 2011 - $68,882) of which $0 remains as of December 31, 2013 (2012 - $4). The gain is amortized into income in proportion to the actual paydown of the reserves acquired.

	Prior period development arises from changes to loss estimates recognized in the current year that relate to loss reserves first reported in previous calendar years. The development reflects changes in the actuarial assessments of the ultimate losses under the relevant reinsurance policies.

	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 premium written, effective as of 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.

	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%.

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% (the “AmTrust Loss Corridor”). For the purposes of determining whether the loss ratio falls within the AmTrust Loss Corridor, workers' compensation business written in AmTrust's Specialty Program segment from July 1, 2007 through December 31, 2012 is excluded from the loss ratio calculation. Above and below the defined corridor, Maiden Bermuda will continue to reinsure losses at its proportional 40% share per the Reinsurance Agreement.

	Collateral provided to AmTrust

	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 Bermuda has agreed to provide appropriate collateral to secure its proportional share under the Reinsurance Agreement of AII's obligations to the AmTrust subsidiaries to whom AII is required to provide collateral.

AII has agreed that, if an AmTrust subsidiary returns to AII excess assets withdrawn from a Trust Account, drawn on a Letter of Credit or maintained by such AmTrust subsidiary as Withheld Funds, AII will immediately return to Maiden Bermuda its proportionate share of such excess assets. AII has further agreed that if the aggregate fair market value of the amount of Maiden Bermuda's assets held in the Trust Account exceeds Maiden Bermuda's proportionate share of AII's obligations, or if an AmTrust subsidiary misapplies any such collateral, AII will immediately return to Maiden Bermuda an amount equal to such excess or misapplied collateral, less any amounts AII has paid to Maiden Bermuda. In addition, if an AmTrust subsidiary withdraws Maiden Bermuda's assets from a Trust Account and maintains those assets on its books as withheld funds, AII has agreed to pay to Maiden Bermuda interest at the rate equivalent to the one-month LIBOR plus 90 basis points per annum computed on the basis of a 360-day year on the loan (except to the extent Maiden Bermuda's proportionate share of AII's obligations to that AmTrust subsidiary exceeds the value of the collateral Maiden Bermuda has provided), and net of unpaid fees Maiden Bermuda owes to AII Insurance Management Limited ("AIIM") and its share of fees owed to the trustee of the Trust Account.

	•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.

AIIB may, if mutually agreed, also produce reinsurance business for the Company from other ceding companies, and in such cases the Company will negotiate a mutually acceptable commission rate. Following the initial one-year term, the agreement may be terminated upon 30 days written notice by either party.

NGHC Quota Share Reinsurance Agreement

Maiden Bermuda, effective March 1, 2010, reinsures 25% of the net premiums of the GMAC personal lines business, pursuant to a quota share reinsurance agreement (“NGHC Quota Share”) with the GMAC personal lines insurance companies, as cedents, and Maiden Bermuda. Maiden Bermuda has a 50% participation in the NGHC Quota Share, by which it receives 25% of net premiums of the personal lines automobile business. The NGHC Quota Share provides that the reinsurers, severally, in accordance with their participation percentages, shall receive 50% of the net premium of the GMAC personal lines insurance companies and assume 50% of the related net losses. The NGHC Quota Share has an initial term of three years and shall renew automatically for successive three years terms unless terminated by written notice not less than nine months prior to the expiration of the current term. Notwithstanding the foregoing, Maiden Bermuda's participation in the NGHC Quota Share may be terminated by NGHC on 60 days written notice in the event Maiden Bermuda becomes insolvent, is placed into receivership, its financial condition is impaired by 50% of the amount of its surplus at the inception of the NGHC Quota Share or latest anniversary, whichever is greater, is subject to a change of control, or ceases writing new and renewal business. NGHC also may terminate the agreement on nine months written notice following the effective date of initial public offering or private placement of stock by NGHC or a subsidiary. Maiden Bermuda may terminate its participation in the NGHC Quota Share on 60 days written notice in the event NGHC is subject to a change of control, ceases writing new and renewal business, effects a reduction in their net retention without Maiden Bermuda's consent or fails to remit premium as required by the terms of the NGHC Quota Share.

The NGHC Quota Share provides that the reinsurers pay a provisional ceding commission equal to 32.5% of ceded earned premium, net of premiums ceded by the personal lines companies for inuring reinsurance, subject to adjustment.The ceding commission is subject to adjustment to a maximum of 34.5% if the loss ratio for the reinsured business is 60.0% or less and a minimum of 30.5% if the loss ratio is 64.5% or greater.

Effective October 1, 2012, the parties amended the reinsurance agreement to decrease the provisional ceding commission from 32.5% to 32.0% of ceded earned premium, net of premiums ceded by the personal lines companies for inuring reinsurance, subject to adjustment.

On August 1, 2013, the Company received notice from NGHC of the termination of the NGHC Quota Share effective on that date. The Company and NGHC mutually agreed that the termination is on a run-off basis, which means that Maiden Bermuda continues to earn premiums and remain liable for losses occurring subsequent to August 1, 2013 for any policies in force prior to and as of August 1, 2013 until those policies expire.

	a) Concentrations of Credit Risk

	As of December 31, 2013 and 2012, the Company’s assets primarily consisted of investments, cash, loan to related party and reinsurance balances receivable.

	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 and its reinsurance balances receivable, within which the largest balance is due from AmTrust. To mitigate credit risk, we generally have a contractual right of offset thereby allowing us to settle claims net of any premiums or loan receivable. The Company believes these balances will be fully collectible.

	b) Concentrations of Revenue

	During 2013, our gross premiums written from AmTrust and NGHC accounted for 60.6% (2012 – 56.8%, 2011 – 51.0%) of our total gross premiums written. AmTrust accounted for $1,169,961 or 53.1% (2012 – $840,346 or 42.0%, 2011 – $669,283 or 36.9%) and NGHC accounted for $164,567 or 7.5% ( 2012 – $295,646 or 14.8%, 2011 – $256,201 or 14.1%).

	c) Brokers

	We produce our reinsurance business for our Diversified Reinsurance segment primarily through brokers. During 2013, three brokers accounted for 49.7% (2012 – 49.7%, 2011 – 59.7%) of our total gross premiums written through brokers for the Diversified Reinsurance segment. Marsh Inc. (including Guy Carpenter) accounted for 20.9% (2012 – 24.1%, 2011 – 27.4%), Aon Benfield Inc. for 19.7% (2012– 13.5%, 2011 – 18.1%) and Beach & Associates, Ltd. for 9.1% (2012 – 12.1%, 2011 – 14.2%).

	11. Commitments and Contingencies (continued)

	d) Letters of Credit

	As of December 31, 2013 and 2012, we had letters of credit outstanding of $93,860 and $91,821, respectively. The letters of credit are secured by cash and fixed maturities with a fair value of $99,482 (2012 - $113,717).

	e) Employment agreements

	The Company has entered into employment agreements with certain individuals. The employment agreements provide for option awards, executive benefits and severance payments under certain circumstances.

	f) Operating Lease Commitments

	The Company leases office space, an apartment, equipment and vehicles under operating leases expiring in various years through 2017. The Company's office space lease in Hamilton, Bermuda for Maiden Holdings and Maiden Bermuda, which expires on November 30, 2017, has an option to renew for another five years. The Company's total rent expense for the years ended December 31, 2013, 2012 and 2011 was $2,286, $2,485 and $2,283, respectively. Future minimum lease payments as of December 31, 2013 under non-cancellable operating leases for the next five years are approximately as follows:


		31-Dec-13
	2014	$	2,004

	2015	1,345

	2016	717

	2017	593

	2018	—

		$	4,659


	g) Unfunded Commitments

	The Company has an unfunded commitment on its investment in limited partnerships of approximately $2,088 as of December 31, 2013.

	h) Loans and Other Collateral

	Please see "Note 10. Related Party Transactions" for the discussion related to loan provided to AmTrust.

	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 account 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 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 TRUPS 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.

11. Commitments and Contingencies (continued)

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. A hearing is presently scheduled to begin in May 2014. 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.

	The Company's common shares have a par value of $0.01 per share. The holders of our common shares are entitled to receive dividends and are allocated one vote per common share, subject to downward adjustment under certain circumstances.

	On December 24, 2012, the Company adopted a written trading plan to facilitate the repurchase of its common shares in accordance with the Company's existing share purchase reauthorization whereby in August 2012, the Board of Directors approved the repurchase of up to $75 million of the Company's common shares. During the years ended December 31, 2013, and 2012 there were no common shares repurchased by the Company.

	(b) Mandatory Convertible Preference Shares - Series B
	In October 2013, the Company issued a total of 3,300,000 7.25% Mandatory Convertible Preference Shares - Series B (the "Preference Shares - Series B"), par value $0.01, at a price of $50 per preference share. The Company received net proceeds of $159,675 from the offering after deducting issuance costs of $5,325, which was recognized as a reduction in additional paid-in capital. The Preference Shares - Series B are not redeemable. The authorized number of the Preference Shares - Series B is 3,300,000.
	The Company will pay cumulative dividends on each of the Preference Shares - Series B at a rate of 7.25% per annum on the initial liquidation preference of $50 per share (equivalent to $3.625 per annum per Preference Share - Series B or $0.90625 per quarter except on the initial payment date which was $0.745139). Dividends will accrue and accumulate from the date of issuance and, to the extent that the Company has lawfully available funds to pay dividends and the board of directors declares a dividend payable, it will pay dividends quarterly each year commencing on December 15, 2013, up to, and including, September 15, 2016 in cash and on September 15, 2016 or any earlier conversion date in cash, or common shares, or a combination thereof, at the Company’s election and subject to the share cap, which is an amount per share equal to the product of (i) 2 and (ii) the maximum conversion rate of 4.0322, subject to conversion rate adjustments.
	On the mandatory conversion date, September 15, 2016, each of the then-outstanding Preference Shares - Series B will automatically convert into a variable number of the Company’s common shares equal to the conversion rate, which will not be more than 4.0322 of the Company's common shares and not less than 3.2258, subject to conversion rate adjustments, that is based on the volume weighted average price per share of the Company’s common shares over the forty consecutive trading day period beginning on, and including, the forty-second scheduled trading day immediately preceding September 15, 2016 (the "final averaging period"). The mandatory conversion date is the third business day immediately following the last trading day of the final averaging period. The conversion rate will be adjusted from time to time if the Company issues common shares as a dividend, increases the cash dividend from $0.09 per share or in some other cases as described under "Description of the Mandatory Convertible Preference Shares - Conversion Rate Adjustments" of the Form 424B2 Prospectus Supplement filed with the SEC on September 27, 2013.

	At any time prior to September 15, 2016, other than during the fundamental change conversion period (as defined in the prospectus supplement), a holder of mandatory convertible preference shares may elect to convert such holder's mandatory convertible preference shares at the minimum conversion rate of 3.2258 shares of the common stock per mandatory convertible preference share, subject to adjustment as described under "Description of Mandatory Convertible Preference Shares - Conversion Rate Adjustments" of the Form 424B2 Prospectus Supplement filed with the SEC on September 27, 2013.
	The Preference Shares - Series B have no voting rights other than to elect two additional members of the board of directors if dividends on the Preference Shares - Series B have not been declared and paid for the equivalent of six or more dividend periods.
	For the year ended December 31, 2013, the Company declared and paid $2,459 in dividends on the Preference Shares - Series B.

	13. Shareholders’ Equity (continued)

	c) Preference Shares - Series A

	On August 22, 2012, the Company issued six million 8.25% Preference Shares - Series A (the “Preference Shares - Series A”), par value $0.01 per share, at a price of $25 per share. The Company received net proceeds of $145,041 from its offering, after deducting issuance costs of $4,959, which was recognized as a reduction in additional paid-in capital. The Preference Shares - Series A have no stated maturity date and are redeemable in whole or in part at the option of the Company any time after August 29, 2017 at a redemption price of $25 per preference share plus any declared and unpaid dividends, without accumulation of any undeclared dividends. The authorized number of the Preference Shares - Series A is 6,000,000.

	Dividends on the Preference Shares - Series A are non-cumulative. Consequently, in the event dividends are not declared on the Preference Shares - Series A for any dividend period, holders of Preference Shares - 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. The holders of Preference Shares - Series A will be entitled to receive dividend payments only when, as and if declared by the Company's board of directors or a duly authorized committee of the board of directors. Any such dividends will be payable from, and including, the date of original issue on a non-cumulative basis, quarterly in arrears.

	To the extent declared, these dividends will accumulate, with respect to each dividend period, in an amount per share equal to 8.25% of the $25 liquidation preference per annum. During any dividend period, so long as any Preference Shares - Series A remain outstanding, unless the full dividends for the latest completed dividend period on all outstanding Preference Shares - Series A have been declared and paid, no dividend shall be paid or declared on the common shares.

	The holders of the Preference Shares - Series A 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 years ended December 31, 2013 and 2012, the Company declared and paid $12,375 and $3,644 in dividends, respectively on the Preference Shares - Series A.

Share Compensation and Pension Plans	12 Months Ended
	Dec. 31, 2013
Share-based Compensation [Abstract]	'
Share Compensation and Pension Plans	'
	Share Compensation and Pension Plans

	The Company’s Amended and Restated 2007 Share Incentive Plan (the “Plan”), provides for grants of options, restricted common shares and restricted share units. The total number of common shares currently reserved for issuance under the Plan is 10,000,000. The Plan is administered by the Compensation Committee of the Board of Directors.

	Restricted Shares and Share Units

	The fair value of each restricted share or 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 over the requisite service period as determined by the Compensation Committee of the Board of Directors.

	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 Compensation 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.

	14. Share Compensation and Pension Plans (continued)

	The key assumptions used in determining the fair value of options granted in 2013, 2012 and 2011 and a summary of the methodology applied to develop each assumption were as follows:


			2013			2012			2011
	Assumptions:
	Volatility		45.30 – 51.40	%		45.30 – 47.60	%		45.55 – 47.60	%
	Risk-free interest rate		0.85 – 1.77	%		0.85 – 1.29	%		1.29 – 1.62	%
	Weighted average expected lives in years		6.1 years			6.1 years			6.1 years
	Forfeiture rate		1.60 – 3.45	%		1.6	%		0	%
	Dividend yield rate		3.46 – 3.55	%		3.04 – 3.55	%		3.04 – 3.27	%

	Expected Price Volatility — This is a measure of the amount by which a price has fluctuated or is expected to fluctuate. Maiden began trading on May 6, 2008, thus, has a maximum of 5.6 year trading history for estimating historical volatility. Maiden's expected volatility for 2013 of 51.4% was based on the average of its historical volatility, measured over the maximum available term of 5.6 years. Prior to 2013, it was not possible to use actual experience to estimate the expected volatility of the price of the common shares in estimating the value of the options granted because the Company's common shares only began trading in May 2008, thus, it does not have enough history over which to calculate an expected volatility representative of the volatility over the expected lives of the options. As a substitute for such estimate, the Company blended its historical volatility with the historical volatilities of a set of comparable companies in the industry in which the Company operates.

	Risk-Free Interest Rate — This is based on the yields on U.S. Treasury constant maturity notes with a term equal to the expected life of the option. An increase in the risk-free interest rate will increase compensation expense.

	Expected Lives — This is the period of time over which the options granted are expected to remain outstanding giving consideration to vesting schedules, historical exercise and forfeiture patterns. The Company uses the simplified method outlined in SEC Staff Accounting Bulletin No. 107 to estimate expected lives for options granted during the period as historical exercise data is not available and the options meet the requirements set out in the Bulletin. Options granted have a maximum term of ten years. An increase in the expected life will increase compensation expense.

	Forfeiture Rate — This is the estimated percentage of options granted that are expected to be forfeited or cancelled before becoming fully vested. An increase in the forfeiture rate will decrease compensation expense.

	Dividend Yield — This is calculated by dividing the expected annual dividend by the share price of the Company at the valuation date. An increase in the dividend yield will decrease compensation expense.

	14. Share Compensation and Pension Plans (continued)

	The following schedule shows all options granted, exercised, expired and exchanged under the Plan for the years ended December 31, 2013, 2012 and 2011:

Total options exercisable at December 31, 2013	2,208,517			$	6.57						5.55 years		$	9,590		$3.28 – 10.00


The weighted average grant date fair value was $2.03, $2.05 and $2.01 for all options outstanding at December 31, 2013, 2012 and 2011, respectively. There was $513 (2012 - $1,528) of total unrecognized compensation cost related to non-vested options as of December 31, 2013 which will be recognized during the next 4 years. Cash in the amount of $1,776 was received from employees as a result of employee share option exercises during the year ended December 31, 2013 (2012 – $478; 2011 – $422). The Company issues new common shares upon the exercise of an option. In connection with these exercises, there was no tax benefit realized by the Company.

Performance-Based Restricted Share Units (PB-RSUs)

The Compensation Committee of the Board of Directors (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-RSUs to executive officers and senior Company employees. The formula for determining the amount of PB-RSUs 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 Global Select Market of our common shares on that date. The grants are performance based which require that certain criteria such as return on equity, underwriting performance, revenue growth and operating expense be met during the performance period to attain a payout. Each metric has a corresponding weighted percentage with a target, threshold and maximum level of performance goal set to achieve a payout. Settlement of the grants can be made in either common shares or cash upon the decision of the Committee. The first performance cycle was for two years, 2011-2012, and subsequent performance cycles are for three years. For the years 2011-2012, no RSUs vested as the target level of performance was not met.

Effective February 19, 2013, the Committee approved the award of PB-RSUs to executive officers and senior Company employees for the fiscal years 2013-2015. All prior, current and future PB-RSUs are paid 50% based on criteria such as return on equity, underwriting performance, revenue growth and operating expense being met during the performance period, while the other 50% of the payout is at the discretion of the Committee based on individual performance. For the year ended December 31, 2013, no accrual was recognized as the calculated weighted percentage of the performance results of the Company did not meet the target levels.

14. Share Compensation and Pension Plans (continued)

CEO Non-Performance-Based Restricted Share Units

On March 1, 2012, the Committee approved an award of NPB-RSUs to the Company's CEO. The award consists of 86,705 restricted share units which fully vested on December 31, 2013 and the units shall be settled no later than 2.5 months after December 31, 2013.

	Taxation

	Under current Bermuda law, Maiden Holdings and Maiden Bermuda, 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 Bermuda 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 Bermuda 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 the U.S. subsidiaries pay a dividend outside the U.S. group, withholding taxes will apply. Our U.S. subsidiaries were under examination for tax years 2009 and 2010. The audits have been closed. There was no impact on the financial statements as a result. Subsequent tax years are not under examination but remain subject to examination in the U.S.

	The Company has subsidiary operations in various other jurisdictions around the world, including but not limited to Australia, Austria, Germany, Netherlands, Russia, Sweden and the U.K., that are subject to relevant taxes in those jurisdictions.

	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 taxation in the country of the paying entity. Currently however, no withholding taxes have been accrued.

	There were no unrecognized tax benefits at December 31, 2013, 2012 and 2011.

	15. Taxation (continued)

	Income tax expense for the years ended December 31, 2013, 2012 and 2011 was as follows:



	For the Year Ended December 31,		2013				2012			2011

	Current tax expense – Domestic (Bermuda)		$	—			$	—		$	—

	Current tax expense – Foreign (U.S. and others)		873				1,020			632

	Total current tax expense		873				1,020			632

	Deferred tax expense – Domestic (Bermuda)		—				—			—

	Deferred tax expense – Foreign (U.S. and others)		990				1,193			1,295

	Total deferred tax expense		990				1,193			1,295

	Total income tax expense		$	1,863			$	2,213		$	1,927


	The following table is a reconciliation of the actual income tax rate for the years ended December 31, 2013, 2012 and 2011 to the amount computed by applying the effective tax rate of 0.0% under Bermuda law to income before taxes:



	For the Year Ended December 31,		2013				2012			2011

	15. 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 our deferred tax assets and liabilities as of December 31, 2013 and 2012 were as follows:


December 31,		2013				2012
Deferred tax assets:
Net operating losses		$	51,569			$	42,014

Unearned premiums		9,364				8,929

Discounting of net loss and loss adjustment expense reserves		11,678				10,585

Net unrealized losses on investments		5,236				—

Accruals not currently deductible		1,879				88

Amortization of intangibles		3,093				2,988

Others		1,065				913

Deferred tax assets before valuation allowance		83,884				65,517

Valuation allowance		67,013				41,231

Deferred tax assets, net		16,871				24,286

Deferred tax liabilities:

Deferred commission and other acquisition expenses		15,587				13,054

Indefinite lived intangible		2,870				2,870

Amortization of goodwill		5,997				4,837

Net unrealized gains on investments		—				10,249

Market discount on bonds		499				488

Others		606				488

Deferred tax liabilities		25,559				31,986

Net deferred tax liability		$	8,688			$	7,700


The net deferred tax liability at December 31, 2013 is $8,688. A valuation allowance has been established against the net U.S. deferred tax assets which is primarily attributable to net operating losses, unearned premium and loss reserve discounting. At this time, we believe it is necessary to establish a valuation allowance against the net deferred tax assets due to insufficient positive evidence regarding the utilization of these losses. During 2013, the Company recorded an increase in the valuation allowance of $10,313 (2012 - $6,104) which was recorded in the Consolidated Statements of Income and an increase of $15,469 (2012 - decrease of $1,081) was recorded as a component of other comprehensive income in shareholders’ equity.

At December 31, 2013, the Company has an available U.S. net operating loss carry-forward of approximately $147,339 for income tax purposes which expires beginning in 2029.

Statutory_Financial_Informatio

Statutory Financial Information	12 Months Ended
	Dec. 31, 2013
Statutory Financial Information [Abstract]	'
Statutory Financial Information	'
	Statutory Financial Information

	Under The Insurance Act 1978 (Bermuda), amendments thereto and related regulations (the “Insurance Act”), Maiden Bermuda is required to prepare Statutory Financial Statements and to file a Statutory Financial Return in Bermuda. The Insurance Act also requires Maiden Bermuda to maintain a minimum share capital of $120. To satisfy these requirements, the statutory capital and surplus of Maiden Bermuda at December 31, 2013 was approximately $1,106,098 (2012 – $943,407) and the amount required to be maintained under Bermuda law, the Minimum Solvency Margin ("MSM"), was $255,327 (2012 – $230,164), respectively. Maiden Bermuda was also required to maintain a minimum liquidity ratio. All requirements were met by Maiden Bermuda throughout the period. In addition, Maiden Bermuda is subject to statutory and regulatory restrictions under the Insurance Act that limit the maximum amount of annual dividends or distributions to be paid by Maiden Bermuda to Maiden Holdings without notification to the Bermuda Monetary Authority (the "BMA") of such payment (and in certain cases prior approval of the BMA). Maiden Bermuda is also restricted in paying dividends that would result in Maiden Bermuda failing to comply with the enhanced capital requirement ("ECR") as calculated based on the Bermuda Solvency Requirement ("BSCR"). Maiden Bermuda is currently completing its BSCR as of December 31, 2013 and it is anticipated Maiden Bermuda will be allowed to pay dividends or distributions not exceeding $218,161.

	16. Statutory Financial Information (continued)

	Maiden Bermuda is 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 dividends it files with the BMA an affidavit that it will continue to meet its minimum capital requirements as described above. In addition, Maiden Bermuda must 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.
	In accordance with the BMA's Insurance (Group Supervision) Rules 2011 all groups for which the BMA is Group Supervisor are also subject to regulatory capital requirements. The BMA acts as group supervisor of Maiden Holdings and its subsidiaries and has advised that Maiden Bermuda is the designated insurer. These regulations require that a group’s available statutory capital and surplus should be equal to or exceed the value of both its MSM and ECR. The Company has complied with its regulatory capital requirements at December 31, 2013.

	Maiden Bermuda is registered as a Class 3B reinsurer under the Insurance Act and therefore must maintain capital at a level equal to its ECR which is established by reference to the BSCR model. The BSCR employs a standard mathematical model that correlates the risk underwritten to the capital that is dedicated to the business. The regulatory requirements are designed to have insurers operate at or above a threshold capital level, which exceeds the BSCR. While not specifically referred to in the Insurance Act, the BMA has established a target capital level (“TCL”) for each Class 3B insurer equal to 120% of its ECR. While a Class 3B insurer is not currently required to maintain its statutory capital and surplus at this level, the TCL serves as an early warning tool for the BMA and failure to maintain statutory capital at least equal to the TCL will likely result in increased BMA regulatory oversight. Maiden Bermuda is currently completing its BSCR as of December 31, 2013 and believes that it exceeds the ECR level of required capital.

	For Bermuda registered insurance companies, there are some differences between financial statements prepared in accordance with U.S. GAAP and those prepared on a statutory basis. Certain assets are non-admitted under Bermuda regulations and so deferred commission and other acquisition expenses have been fully expensed and prepaid expenses and fixed assets removed from the statutory balance sheet. The Company’s insurance subsidiaries in the U.S., Maiden US and Maiden Specialty, file financial statements in accordance with statutory accounting practices (“SAP”) prescribed or permitted by state insurance regulatory authorities. The minimum statutory capital necessary to satisfy regulatory requirements for Maiden US and Maiden Specialty for the year ended December 31, 2013 are $1,200 and $45,000, respectively (2012 - $1,200 and $45,000, respectively). These requirements were met by Maiden US and Maiden Specialty throughout the year ended December 31, 2013. Without prior approval of its domiciliary commissioner, dividends to shareholders are limited by the laws of the U.S. companies’ state of domicile, Missouri and North Carolina, respectively, to the greater of 10% of statutory policyholders’ surplus as of the preceding December 31, or net income, less net realized capital gain on investments, for the 12-month period ending December 31 of the preceding year. Accordingly, the maximum dividend payments that can be made in the next year without prior approval by the Missouri Department of Insurance and North Carolina Department of Insurance is $0 and $4,894, respectively.

	The Company’s insurance subsidiary in Sweden, Maiden LF, is regulated by the Swedish Finansinspektionen (“Swedish FSA”). Maiden LF was required to maintain a minimum level of statutory capital and surplus of $5,096 at December 31, 2013 (2012 - $4,881). This requirement was met by Maiden LF throughout the period. The statutory assets were approximately $37,413 (2012 - $29,378). 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 the Company. As of December 31, 2013, Maiden LF is allowed to pay dividends or distributions not exceeding $2,272.

	As of December 31, 2013, the Company's net assets were $1,124,295 (2012- $1,015,611), of which $264,629 (2012 - $285,113) are restricted primarily as a result of statutory restrictions on the Company's insurance subsidiaries as well as collateral requirements under various reinsurance agreements.

	The Statutory equity and net income of the Company's insurance and reinsurance subsidiaries were as follows:


		Maiden Bermuda		Maiden US			Maiden Specialty		Maiden LF
	Statutory Capital and Surplus
	31-Dec-13	$	1,106,098	$	269,598		$	48,940	$	9,136

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Reporting and Consolidation	'
	Basis of Reporting and Consolidation — These Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The Consolidated Financial Statements 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 in the Consolidated Financial Statements. Certain prior year comparatives have been reclassified to conform to the current year presentation.
Estimates	'
	Estimates — The preparation of these Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported 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 differ from those estimates. The significant estimates reflected in the Company’s financial statements include, but are not limited to:


	•	reserve for loss and loss adjustment expenses;


	•	recoverability of deferred commission and other acquisition expenses;


	•	determination of impairment of goodwill and other intangible assets;


	•	valuation of financial instruments; and


	•	determination of other-than-temporary impairment of investments.
Investments	'
	Investments — The Company currently classifies all of its fixed maturity investments as “available-for-sale” and, accordingly, they are carried at estimated fair value. The fair value of fixed maturity securities is generally determined from quotations received from nationally recognized pricing services, 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 accounts for its other investments at fair value in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 944, “Financial Services” (“ASC 944”). Other investments primarily comprise 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. Unrealized gains or losses on other investments are reported as a component of accumulated other comprehensive income.

	2. Significant Accounting Policies (continued)

	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 interest and dividend income together with amortization of market premiums and discounts using the effective yield method and is net of investment management fees and other expenses. For mortgage-backed securities 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.

	Impairments of investment securities results in a charge to operations when a market decline below cost is deemed to be other than temporary. To determine the recovery period of a fixed maturity security, we consider the facts and circumstances surrounding the underlying issuer including, but not limited to, the following:


	•	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.

	When assessing our intent to sell a fixed maturity security or if it is more likely that we will be required to sell a fixed maturity security before recovery of its cost basis, we evaluate facts and circumstances such as, but not limited to, decisions to reposition our security portfolio, sale of securities to meet cash flow needs and sales of securities to capitalize on favorable pricing. In order to determine the amount of the credit loss for a fixed maturity security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The discount rate is the effective interest rate implicit in the underlying fixed maturity security. The effective interest rate is the original yield or the coupon if the fixed maturity security was previously impaired. If an other-than-temporary impairment (“OTTI”) exists and we have the intent to sell the security, we conclude that the entire OTTI is credit-related and the amortized cost for the security is written down to current fair value with a corresponding charge to realized loss on our Consolidated Statements of Income. If we do not intend to sell a fixed maturity security or it is not more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost but the present value of the cash flows expected to be collected is less than the amortized cost of the fixed maturity security (referred to as the credit loss), we conclude that an OTTI has occurred and the amortized cost is written down to the estimated recovery value with a corresponding charge to realized loss on our Consolidated Statements of Income, as this is also deemed the credit portion of the OTTI. The remainder of the decline to fair value is recorded to other comprehensive income (“OCI”), as an unrealized OTTI loss on our Consolidated Balance Sheets, as this is considered a noncredit (i.e. recoverable) impairment.
Fair Value Measurements	'
	Fair Value Measurements — FASB 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 securities, 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: listed derivatives that are not actively traded; U.S. government-sponsored agency securities; non-U.S. government obligations; corporate and municipal bonds; mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”); short-duration high yield fund, and over-the-counter (“OTC”) derivatives (e.g. foreign currency options and forward contracts); 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; hedge and credit funds with partial transparency; and collateralized loan obligation (“CLO”) — equity tranche securities that are traded in less liquid markets.


	2. Significant Accounting Policies (continued)

	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, a nationally recognized pricing service provider (“Pricing Service”). When quoted market prices are unavailable, the Company utilizes a 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 a 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 transactio
Cash and Cash Equivalents	'
	Cash and Cash Equivalents — The Company maintains its 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. Accordingly, changes in restricted cash and cash equivalents are reported as an investing activity in our Consolidated Statements of Cash Flows. The Company maintains certain cash and investments in trust accounts to be used primarily as collateral for unearned premiums and loss and loss adjustment expenses reserves owed to insureds. The Company is required to maintain minimum balances in these accounts based on pre-determined formulas. See "Note 4. (e) Investments" for additional details.
Premiums and Related Costs	'
	Premiums and Related Costs — For pro-rata contracts and excess-of-loss contracts where no deposit or minimum premium is specified in the contract, written premium is recognized based on estimates of ultimate premiums provided by the ceding companies. Initial estimates of written premium 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 12 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.

	The unearned portion of reinsurance purchased by the Company (retrocession or reinsurance premiums ceded) is reported as prepaid reinsurance premiums 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. Reserves are established for the unexpensed portion of premiums ceded and losses recoverable are recorded as an asset called reinsurance recoverable on unpaid losses. Premiums earned are reported net of reinsurance in the Consolidated Statements of Income.

	Assumed and ceded reinsurance contracts that lack a significant transfer of risk are treated as deposits.

	Acquisition expenses represent the costs of writing business that vary with, and are primarily related to, the production of insurance and reinsurance business. Policy and contract acquisition expenses, including assumed commissions and other direct operating expenses that are related to successful contracts are deferred and recognized as expense as related premiums are earned.

	Only certain costs incurred in the successful acquisition of new and renewal insurance contracts are capitalized. Those costs include incremental direct costs of contract acquisition that result directly from and are essential to the contract transaction and would not have been incurred had the contract transaction not occurred. All other acquisition-related costs, such as costs incurred for soliciting business, administration, and unsuccessful acquisition or renewal efforts are charged to expense as incurred. Administrative costs, including rent, depreciation, occupancy, equipment, and all other general overhead costs are considered indirect costs and are expensed as incurred.

	2. Significant Accounting Policies (continued)
Loss and Loss Adjustment Expenses Incurred	'
	Loss and Loss Adjustment Expenses Incurred — Loss and loss adjustment expenses (“LAE”) represent the estimated ultimate net costs of all reported and unreported losses incurred through December 31. The reserve for loss and LAE is estimated using individual case-basis valuations and statistical analysis and is not discounted. 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. In estimating reserves, the Company utilizes a variety of standard actuarial methods. The estimates are continually reviewed and adjusted as necessary as experience develops or new information becomes known. Such adjustments are included in current operations.
Capital Assets	'
	Capital Assets — Capital assets are recorded at cost. Maintenance and repairs are charged to operations as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets, as follows:


	Furniture and fixtures	3 – 7 years
	Computer equipment and software	3 years
	Vehicles	3 years
	Leasehold improvements	Lease term
Business Combinations, Goodwill and Intangible Assets	'
	Business Combinations, 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. Other intangible assets with an indefinite useful life are not amortized.

	Goodwill and other indefinite life intangible assets are tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. Definite life intangible assets are reviewed for indicators of impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable, and tested for impairment if appropriate. For purposes of the annual impairment evaluation, goodwill is assigned to the applicable reporting unit of the acquired entities giving rise to the goodwill.

	The Company has established October 1 as the date for performing its annual impairment tests. If goodwill or other intangible assets are impaired, they are written down to their estimated fair values with a corresponding loss reflected in the Company’s Consolidated Statements of Income.
Non Controlling Interests	'
	Noncontrolling Interests — The Company accounts for its noncontrolling interests in accordance with FASB ASC Topic 810 “Consolidations”, and presents such noncontrolling shareholders' interest in the equity section of the Company’s Consolidated Balance Sheets. Net income (loss) attributable to noncontrolling interests is presented separately in the Company’s Consolidated Statements of Income.
Income Taxes	'
	Income Taxes — The Company accounts for income taxes using FASB ASC Topic 740 “Income Taxes” for its 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 are included as income tax expense.
Share Compensation Expense	'
	Share Based Compensation Expense — The Company recognizes the compensation expense for share option, restricted share and share unit grants, based on the fair value of the award on the date of grant, over the vesting period, which is the requisite service period. The fair value of the grant will be amortized ratably over its vesting period as a charge to compensation expense and an increase to additional paid in capital in Shareholders’ Equity.

	2. Significant Accounting Policies (continued)

Earnings Per Share	'
	Earnings Per Share — Basic earnings per share are computed based on the weighted-average number of common shares outstanding. 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 using the treasury stock method and the mandatory convertible preference shares using the if-converted method.
Treasury Shares	'
	Treasury Shares — Treasury shares are common shares repurchased by the Company and not subsequently cancelled. These shares are recorded at cost and result in a reduction of our 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, we translate monetary assets and liabilities denominated in foreign currencies at year-end exchange rates, with the 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 investments, cash and cash equivalents, reinsurance balances receivable, reserve for loss and loss adjustment expenses 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 subsidiaries and divisions, whose functional currency is not the U.S. dollar, are translated at prevailing year-end exchange rates. Revenues and expenses of such foreign entities are translated at average exchange rates during the year. The effects of the translation adjustments for foreign entities are included in accumulated other comprehensive income.
Recently Adopted Accounting Standards Updates	'
	Recently Adopted Accounting Standards Updates

	Comprehensive Income - Reporting of amounts reclassified out of Accumulated Other Comprehensive Income

	In February 2013, the FASB issued Accounting Standards Update ("ASU") 2013-02, which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. The ASU expands the current disclosure guidance by requiring entities to present separately, for each component of other comprehensive income, current period reclassifications out of accumulated other comprehensive income and other amounts of current period other comprehensive income. Entities may present the disaggregation either on the face of the statement where net income is presented or in the notes to the financial statements. The Company has opted to present this disaggregation of the components of other comprehensive income in the notes to the financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. Early adoption of the guidance is permitted and shall be applied prospectively. The adoption of this guidance as of January 1, 2013 did not have any effect on the Company's results of operations, financial position or liquidity.

	Balance Sheet Offsetting

	In December 2011, the FASB issued new guidance requiring additional disclosures about financial instruments and derivative instruments that are either: (1) offset for balance sheet presentation purposes or (2) subject to an enforceable master netting arrangement or similar arrangement, regardless of whether they are offset for balance sheet presentation purposes. This guidance is effective at January 1, 2013, with retrospective presentation of the new disclosures required. As this new guidance is disclosure-related only and does not amend the existing balance sheet offsetting guidance, the adoption of this guidance did not have any effect on the Company's results of operations, financial position or liquidity.

	Qualitative Impairment Test For Indefinite-Lived Intangibles

	On July 27, 2012, the FASB issued final guidance adding an optional qualitative assessment for determining whether an indefinite-lived intangible asset is impaired. This ASU 2012-02 is similar to the goodwill guidance which allows companies to perform a qualitative assessment to test goodwill for impairment. This guidance gives companies the option to first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50%) that an indefinite-lived intangible asset is impaired. If a company determines that it is more likely than not that the fair value of such asset exceeds its carrying amount, it would not need to calculate the fair value of the asset in that year. However, if a company concludes otherwise, it must calculate the fair value of the asset, compare that value with its carrying amount and record an impairment charge, if any. To perform a qualitative assessment, a company must identify and evaluate changes in economic, industry and company-specific events and circumstances that could affect the significant inputs used to determine the fair value of an indefinite-lived intangible asset. The guidance became effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company adopted this guidance on January 1, 2013. The adoption of this guidance did not have any effect on the Company's results of operations, financial position or liquidity.

	2. Significant Accounting Policies (continued)

	Technical Corrections and Improvements

	In October 2012, FASB issued ASU 2012-04, Technical Corrections and Improvements. The amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Additionally, the amendments make the Codification easier to understand and the fair value measurement guidance easier to apply by eliminating inconsistencies and providing needed clarifications. Transition guidance is provided for amendments the FASB believes could change practice. The amendments in this ASU that do not have transition guidance are effective upon issuance for both public and nonpublic entities. For public entities, the amendments that are subject to the transition guidance became effective for fiscal periods beginning after December 15, 2012. This guidance did not have any effect on the Company's results of operations, financial position or liquidity.
	Recently Issued Accounting Standards Updates Not Yet Adopted
	Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity

	In March 2013, FASB issued ASU 2013-05 with the objective of resolving the diversity about whether ASC 810-10, Consolidation - Overall, or ASC 830-30, Foreign Currency Matters - Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity.

	Under this guidance, when a reporting entity that is also the parent entity, ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity, the parent is required to apply the guidance in ASC 830-30 to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Additionally, for an equity method investment that is a foreign entity, the partial sale guidance in ASC 830-30-40 continues to be applicable. As such, a pro rata portion of the cumulative translation adjustment should be released into net income upon a partial sale of such an equity method investment. However, this treatment does not apply to an equity method investment that is not a foreign entity. In those instances, the cumulative translation adjustment is released into net income only if the partial sale represents a complete or substantially complete liquidation of the foreign entity that contains the equity method investment.

	Furthermore, the amendments in this ASU clarify that the sale of an investment in a foreign entity includes both: (1) events that result in the loss of a controlling financial interest in a foreign entity (that is, irrespective of any retained investment); and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date (sometimes also referred to as a step acquisition). Accordingly, the cumulative translation adjustment should be released into net income upon the occurrence of those events.

	The amendments in this ASU are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The amendments should be applied prospectively to derecognition events occurring after the effective date. Prior periods should not be adjusted. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company's results of operations, financial condition or liquidity.

	Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry-forward, a Similar Tax Loss, or a Tax Credit Carry-forward Exists

	On July 18, 2013, FASB issued ASU 2013-11 which provides guidance on the presentation of an unrecognized tax benefit when a net operating loss ("NOL") carry-forward, a similar tax loss, or a tax credit carry-forward exists. Under this ASU, an entity must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a NOL carry-forward, similar tax loss, or a tax credit carry-forward. There are two exceptions to this form of presentation as follows:


	•	To the extent a NOL carry-forward, a similar tax loss, or a tax credit carry-forward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position; and


	•	The entity does not intend to use the deferred tax asset for this purpose.

	2. Significant Accounting Policies (continued)

	If either of these conditions exists, an entity should present an unrecognized benefit in the financial statements as a liability and should not net the unrecognizable tax benefit with a deferred tax asset.

	The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The adoption of this guidance is not expected to have an impact on the Company's results of operations, financial condition or liquidity.
