SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SIGNIFICANT ACCOUNTING POLICIES [Text Block]	2. SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of AXIS Capital, its wholly-owned subsidiaries, and variable interest entities (“VIEs”) in which the Company is considered the primary beneficiary. All inter-company accounts and transactions have been eliminated. A VIE is an entity that either: (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. We are the primary beneficiary of a VIE if we have a controlling financial interest in the VIE, based on the following two characteristics: a) the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE, and b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Tabular dollar and share amounts are in thousands, with the exception of per share amounts. All amounts are reported in U.S. dollars. Use of Estimates The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amount 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. While management believes that the amounts included in the consolidated financial statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company's principal estimates include: reserve for losses and loss expenses; reinsurance recoverable on unpaid losses, including the provision for uncollectible amounts; gross and net premiums written and net premiums earned; recoverability of deferred tax assets; other-than-temporary impairments (“OTTI”) in the carrying value of available-for-sale investment securities; and valuation of certain fixed maturities, other investments and derivatives that are measured using significant unobservable inputs. Our significant accounting policies are: a) Investments Investments available for sale Our fixed maturities and equities classified as “available for sale” are reported at fair value at the balance sheet date. See Note 6 – Fair Value Measurements for additional information regarding the determination of fair value. The change in fair value (net unrealized gain or loss) on our available for sale investments, net of tax, is included as a separate component of accumulated other comprehensive income (loss) (“AOCI”) in shareholders' equity. Net investment income includes interest and dividend income and the amortization of market premiums and discounts and is presented net of investment expenses. Investment income is recognized when earned. Purchases and sales of investments are recorded on a trade-date basis and realized gains/losses on sales of investments are determined based on the specific identification method. We recognize investment income from fixed maturities based on the constant effective yield method, which includes an adjustment for estimated principal repayments, if any. The effective yield used to determine the amortization for fixed maturities subject to prepayment risk (e.g. asset-backed, loan-backed and other structured securities) is recalculated and adjusted periodically based upon actual historical and/or projected future cash flows. The adjustments to the yield for highly-rated prepayable fixed maturities are accounted for using the retrospective method. The adjustments to the yield for other prepayable fixed maturities are accounted for using the prospective method. On a quarterly basis, we assess whether unrealized losses on available for sale investments represent impairments that are other than temporary. Several factors are considered in this assessment including, but not limited to: (i) the extent and duration of the decline, (ii) the reason for the decline (e.g. credit spread widening, credit event), (iii) the historical and implied future volatility of the fair value, (iv) the financial condition and near-term prospects of the issuer and (v) the collateral structure and credit support of the security, if applicable. Effective April 1, 2009, we adopted an updated Financial Accounting Standards Board (“FASB”) guidance for the recognition and presentation of OTTI for fixed maturities. A fixed maturity is impaired when the fair value is below its amortized cost. For an impaired fixed maturity where we intend to sell the security or it is more likely than not that we will be required to sell the security before its anticipated recovery, the full amount of the impairment is charged to earnings and is included in net realized investment gains (losses). Where we intend to hold the impaired fixed maturity, we estimate the anticipated credit loss of the security and recognize only this portion of the impairment in earnings, with the remaining balance of the impairment (non-credit related e.g. interest rates, market conditions, etc.) recognized in AOCI. We impair an equity security in an unrealized loss position when we do not have the ability and intent to hold the security for a reasonable period of time to allow for a full recovery. The full impairment is charged to earnings, in net realized investment gains (losses). Upon recognition of an OTTI, the new cost basis for the security is the previous amortized cost for a fixed maturity or cost for an equity security less the OTTI recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value; except for fixed maturities whereby the difference between the new cost basis and the expected cash flows is accreted on a quarterly basis to net investment income over the remaining life of the fixed maturity. Other investments We record other investments at fair value (see Note 6 – Fair Value Measurements), with both changes in fair value and realized gains/losses reported in net investment income. Short-term investments Short-term investments primarily comprise highly-liquid debt securities with maturities greater than three months but less than one year from the date of purchase. These investments are carried at amortized cost, which approximates fair value. b) Cash and cash equivalents Cash equivalents include money-market funds and fixed interest deposits placed with a maturity of under 90 days when purchased. Cash and cash equivalents are recorded at amortized cost, which approximates fair value due to the short-term, liquid nature of these securities. c) Premiums and Acquisition Costs Premiums Insurance premiums written are recorded in accordance with the terms of the underlying policies. For multi-year policies where premiums are payable in annual installments, premiums are recorded at the inception of the policy based on management's best estimate of total premiums to be received. However, this excludes premiums for the period during which the insured/reinsured has the ability to unilaterally commute or cancel coverage. Reinsurance premiums are recorded at the inception of the policy and are estimated based upon information received from ceding companies. Any subsequent differences arising on insurance and reinsurance premium estimates are recorded in the period they are determined. (Re)insurance premiums are earned over the period during which we are exposed to the underlying risk, which is generally one to two years with the exception of multi-year policies. Unearned premiums represent the portion of premiums written which is applicable to the unexpired risks under contracts in force. Reinstatement premiums are recognized at the time a loss event occurs and coverage limits for the remaining life of the contract are reinstated under pre-defined contract terms; such premiums are earned over the remaining risk period. The accrual of reinstatement premiums is based on our estimate of losses and loss adjustment expenses, which reflects management's judgment, as described in Note 2(d) – Losses and Loss Expenses below. Premiums receivable balances in excess of 90 days past due are reviewed for impairment at least quarterly and an allowance is established for amounts considered uncollectible. The need for charge-off of any amounts previously reserved as uncollectible is assessed on a quarterly basis. Acquisition Costs Acquisition costs vary with and are directly related to the acquisition of (re)insurance contracts and consist primarily of fees and commissions paid to brokers and premium taxes. Premiums receivable are presented net of applicable acquisition costs when contract terms provide for the right of offset. Acquisition costs are shown net of commissions earned on ceded reinsurance. Our net acquisition costs are deferred and charged to expense as the related premium is earned. Anticipated losses and loss expenses, other costs and investment income related to these premiums are considered in assessing the recoverability of our deferred acquisition costs. If deferred amounts are estimated to be unrecoverable, they are expensed. Compensation expenses for personnel involved in contract acquisition, as well as advertising costs, are expensed as incurred. d) Losses and Loss Expenses Our reserve for losses and loss expenses represents an estimate of the unpaid portion of our ultimate liability for losses and loss expenses for (re)insured events that have occurred at or before the balance sheet date. The balance reflects both claims that have been reported to us (“case reserves”) and claims that have been incurred but not yet reported to us (“IBNR”). These amounts are reduced for estimated amounts of salvage and subrogation recoveries. We review our reserve for losses and loss expenses on a quarterly basis. Case reserves are primarily established based on amounts reported from insureds and/or their brokers. Management estimates IBNR after reviewing detailed actuarial analyses and applying informed judgment to consider qualitative factors that may not be fully reflected in the actuarial estimates. A variety of actuarial methods are utilized in this process, including the Expected Loss Ratio, Bornhuetter-Ferguson and Chain Ladder methods. Our estimate is highly dependent on management's judgment as to which method(s) are most appropriate for a particular accident year and class of business. Given our relatively limited operating history, our historical data is often supplemented with industry benchmarks when applying these methodologies. Any adjustments to our previous reserve for losses and loss expenses estimates are recognized in the period they are determined. While we believe that our reserves for losses and loss expenses are adequate, this estimate requires significant judgment and new information, events or circumstances may result in ultimate losses that are materially greater or less than provided for in the Consolidated Balance Sheets. e) Reinsurance In the normal course of business, we purchase reinsurance protection to limit our ultimate losses from catastrophic events and to reduce our loss aggregation risk. The premiums paid to our reinsurers (i.e. premiums ceded) are expensed over the coverage period. Prepaid reinsurance premiums represent the portion of premiums ceded which is applicable to the unexpired term of the contracts in force. Reinstatement-related premiums ceded are recorded at the time a loss event occurs and our coverage limits for the remaining life of a contract are reinstated under pre-defined contract terms; such premiums are expensed over the remaining risk period. Reinsurance recoverable related to our case reserves is estimated on a case-by-case basis by applying the terms of any applicable reinsurance coverage to our individual case reserve estimates. Our estimate of reinsurance recoverable related to our IBNR reserves is generally developed as part of our loss reserving process. Our reinsurance recoverable is presented net of a provision for uncollectible amounts, reflecting the amount we believe will ultimately not be recovered due to reinsurer insolvency, contractual disputes over contract language or coverage and/or some other reason. We apply case-specific provisions against certain recoveries that we deem unlikely to be collected in full. In addition, we use a default analysis to estimate our provision for uncollectible amounts on the remainder of the balance. The estimates of our reinsurance recoverable and the associated provision require management's judgment and are reviewed in detail on a quarterly basis. Any adjustments to amounts recognized in prior periods are reported in our net losses and loss expenses in the Consolidated Statement of Operations for the period when the adjustments were identified. The charge-off of amounts previously reserved as uncollectible is also considered on a case-by-case basis as part of this quarterly process. f) Foreign Exchange The Company's reporting currency is the U.S. dollar. In translating the financial statements of our subsidiaries or branches where the functional currency is other than the U.S. dollar, assets and liabilities are converted into U.S. dollars using the rates of exchange in effect at the balance sheet dates and revenues and expenses are converted using the weighted average foreign exchange rates for the period. The effect of translation adjustments is reported as a separate component of AOCI in shareholders' equity. In recording foreign currency transactions, revenue and expense items are converted to the relevant functional currency at the exchange rate prevailing at the transaction date. Assets and liabilities originating in currencies other than the functional currency are translated into the functional currency at the rates of exchange in effect at the balance sheet date. The resulting foreign currency gains or losses are recognized in the Consolidated Statements of Operations, with the exception of those related to foreign-denominated available for sale investments. For these investments, exchange rate fluctuations represent an unrealized appreciation/depreciation in the value of the securities and are included in the related component of AOCI. g) Share-Based Compensation The Company is authorized to issue restricted stock awards and units, stock options and other equity-based awards to its employees and directors. The fair value of the share-based compensation is measured at the grant date and expensed over the period for which the employee is required to provide services in exchange for the award. The expense associated with awards subject to graded vesting is recognized on a straight-line basis. Forfeiture benefits are estimated at the time of grant and incorporated in the determination of share-based compensation. h) Derivative Instruments Derivative Instruments not Designated as Hedging Instruments We may enter into derivative instruments such as futures, options, interest rate swaps and foreign currency forward contracts as part of our overall foreign currency risk management strategy, to obtain exposure to a particular financial market or for yield enhancement. From time to time we may also enter into (re)insurance contracts that meet the FASB's definition of a derivative contract. We measure all derivative instruments at fair value (see Note 6 – Fair Value Measurements) and recognize them as either assets or liabilities in the Consolidated Balance Sheets. Subsequent changes in fair value and any realized gains or losses are recognized in the Consolidated Statements of Operations. Derivative Instruments Designated as Hedging Instruments We may designate a currency derivative as a hedge of foreign exchange rate-related movements in the fair value of certain investment portfolios. This is referred to as a fair value hedge. Changes in the fair value of the designated fair value hedge, along with the changes in the fair value of the hedged asset attributable to the hedged risk, are recorded in net realized investment gains (losses) in the Consolidated Statements of Operations, along with any hedge ineffectiveness. To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in value of the hedged item. Further, the hedge relationship must be designated and formally documented at the inception, detailing the particular risk management objective and strategy for the hedge, including the item and risk that is being hedged, the derivative that is being used, and how effectiveness will be assessed. We formally measure the hedge effectiveness at inception and on an ongoing basis. We evaluate the effectiveness on a retrospective and prospective basis, using the period-to-period dollar offset method. Using this method, if the hedge correlation is within the range of 80% to 125%, we consider the hedge effective and apply hedge accounting. Cash flows from derivative instruments designated as hedging instruments are presented as operating activities in the Consolidated Statements of Cash Flows. i) Goodwill and Intangible Assets We classify intangible assets into three categories: (1) intangible assets with finite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization, and (3) goodwill. We amortize intangible assets with finite lives over their estimated useful lives in proportion to the estimated economic benefits of the intangible assets. We also test these assets for impairment if circumstances indicate that the carrying value may not be fully recoverable. Such circumstances may include an economic downturn in a geographic market or a change in the assessment of future operations. If, as a result of such an evaluation, we determine that the carrying value of the finite lived intangible assets is not recoverable, the value of the assets will be reduced to fair value with the difference being expensed in the Consolidated Statement of Operations. Our intangible assets with indefinite lives include licenses held by certain subsidiaries in various jurisdictions that allow such subsidiaries to write insurance and/or reinsurance business. These intangible assets are carried at or below estimated fair value and are tested annually for impairment, or more frequently if circumstances indicate that a possible impairment has arisen. We have recorded goodwill in connection with certain acquisitions. Goodwill represents the excess of the cost of acquisitions over the fair value of the net assets acquired and is assigned to applicable reporting unit(s) on the acquisition date based upon the expected benefit to be received by the reporting unit. We determine the expected benefit based on several factors, including the purpose of the business combination, our strategy subsequent to the business combination and the structure of the acquired company subsequent to the business combination. Goodwill is not subject to amortization. We test goodwill for potential impairment during the fourth quarter each year and between annual tests if an event occurs or circumstances change that may indicate that potential exists for the fair value of a reporting unit to be reduced to a level below its carrying amount. Our impairment evaluation is a two-step process and is conducted at the reporting unit level. First, we identify potential impairment by comparing the fair value of the reporting units to estimated book values, including goodwill. The fair value of each reporting unit is derived based upon valuation techniques and assumptions that we believe market participants would use to value our business. The estimated fair values are generally determined utilizing methodologies that incorporate discounted cash flow analyses. The values derived from the analyses are then compared to recent market transactions for reasonableness. We derive the net book value of our reporting units by estimating the amount of shareholders' equity required to support the activities of each reporting unit. If the estimated fair value of a reporting unit exceeds the estimated book value, goodwill is not considered impaired. If the book value exceeds the estimated fair value, the second step compares the implied fair value of the reporting unit's goodwill with the carrying amount of the goodwill in order to determine the magnitude of impairment to be recognized. The implied fair value of goodwill is determined by deducting the fair value of a reporting unit's identifiable assets and liabilities from the fair value of the reporting unit as a whole. The excess of the carrying value of goodwill above the implied goodwill, if any, would be recognized as an impairment charge in the Consolidated Statement of Operations. j) Income Taxes Certain subsidiaries and branches of the Company operate in jurisdictions where they are subject to taxation. Current and deferred income taxes are charged or credited to net income, or in certain cases to AOCI, based upon enacted tax laws and rates applicable in the relevant jurisdiction in the period in which the tax becomes accruable or realizable. Deferred income taxes are provided for all temporary differences between the bases of assets and liabilities used in the Consolidated Balance Sheets and those used in the various jurisdictional tax returns. When our assessment indicates that it is more likely than not that a portion of a deferred tax asset will not be realized in the foreseeable future, a valuation allowance against deferred tax assets is recorded. We recognize the tax benefits of uncertain tax positions only when the position is more-likely-than-not to be sustained upon audit by the relevant taxing authorities. k) Treasury Shares Common shares repurchased by the Company and not subsequently cancelled are classified as treasury shares and are recorded at cost. This results in a reduction of shareholders' equity in the Consolidated Balance Sheets. When shares are reissued from treasury, we use the average cost method to determine the cost of the reissued shares. Gains on sales/reissuances of treasury shares are credited to additional paid-in capital, while losses are charged to additional paid-in capital to the extent that previous net gains from reissued treasury shares were included therein; otherwise losses are charged to retained earnings. l) New Accounting Standards Adopted in 2011 Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts Effective January 1, 2011, we prospectively adopted amended FASB guidance that modified the definition of the types of costs that can be capitalized in relation to the acquisition of new and renewal insurance contracts. The amended guidance requires costs to be incremental or directly related to the successful acquisition of new or renewal contracts in order to be capitalized as a deferred acquisition cost. Capitalized costs would include incremental direct costs, such as commissions paid to brokers. Additionally, the portion of employee salaries and benefits directly related to time spent for acquired contracts would be capitalized. Costs that fall outside the revised definition must be expensed when incurred. In accordance with the transitional provisions of this amended guidance, we elected not to capitalize acquisition costs that we did not previously capitalize, namely those costs related to employee salaries and benefits. The adoption of this guidance did not impact our results of operations, financial condition or liquidity. Comprehensive Income Effective July 1, 2011, we retrospectively adopted FASB guidance revising the manner in which entities present comprehensive income in their financial statements. The amended guidance eliminated the option to report other comprehensive income and its components in the statement of changes in shareholders' equity. Components of comprehensive income may be reported in either 1) a continuous statement of comprehensive income or 2) two separate but consecutive statements. As the new guidance did not change the items that constitute net income and/or other comprehensive income, the timing of reclassifications from other comprehensive income to net income or the earnings per share computation, its adoption did not impact our results of operations, financial condition or liquidity. m) Recently Issued Accounting Policies Not Yet Adopted Fair Value Measurement and Disclosures In May 2011, the FASB amended its existing fair value measurement guidance by: clarifying principal market determination, addressing the fair value measurement of instruments with offsetting market or counterparty credit risks, clarifying that the “valuation premise” and “highest and best use” concepts are not relevant to financial instruments, limiting the application of premiums and discounts, prohibiting the use of blockage factors to all three levels of the fair value hierarchy, and expanding disclosure requirements. If different fair value measurements result from the application of the amended guidance, the difference will be recognized in income in the period of adoption as a change in estimate. The new requirements will be effective January 1, 2012 and the new disclosure requirements are to be applied prospectively. We do not expect that adoption of this amended guidance will significantly impact our results of operations, financial condition or liquidity. Goodwill In September 2011, the FASB issued new guidance providing entities with the option to perform a qualitative assessment prior to calculating the estimated fair value of a reporting unit, the first step of the required annual goodwill impairment test. Entities able to qualitatively conclude that the fair value of a reporting unit more likely than not (a likelihood of more than 50%) exceeds its carrying amount can bypass the existing requirement to perform the quantitative annual impairment test. This guidance will become effective at January 1, 2012 and does not change how an entity measures a goodwill impairment loss; thus, the adoption of this guidance will not impact our results of operations, financial condition 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 will be 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 will not impact our results of operations, financial condition or liquidity.

SIGNIFICANT ACCOUNTING POLICIES [Abstract]

SIGNIFICANT ACCOUNTING POLICIES [Text Block]

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of AXIS Capital, its wholly-owned subsidiaries, and variable interest entities (“VIEs”) in which the Company is considered the primary beneficiary. All inter-company accounts and transactions have been eliminated.

A VIE is an entity that either: (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. We are the primary beneficiary of a VIE if we have a controlling financial interest in the VIE, based on the following two characteristics: a) the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE, and b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE.

Tabular dollar and share amounts are in thousands, with the exception of per share amounts. All amounts are reported in U.S. dollars.

Use of Estimates

The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amount 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. While management believes that the amounts included in the consolidated financial statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company's principal estimates include:

reserve for losses and loss expenses;
reinsurance recoverable on unpaid losses, including the provision for uncollectible amounts;
gross and net premiums written and net premiums earned;
recoverability of deferred tax assets;
other-than-temporary impairments (“OTTI”) in the carrying value of available-for-sale investment securities; and
valuation of certain fixed maturities, other investments and derivatives that are measured using significant unobservable inputs.

Our significant accounting policies are:

a) Investments

Investments available for sale

Our fixed maturities and equities classified as “available for sale” are reported at fair value at the balance sheet date. See Note 6 – Fair Value Measurements for additional information regarding the determination of fair value. The change in fair value (net unrealized gain or loss) on our available for sale investments, net of tax, is included as a separate component of accumulated other comprehensive income (loss) (“AOCI”) in shareholders' equity.

Net investment income includes interest and dividend income and the amortization of market premiums and discounts and is presented net of investment expenses. Investment income is recognized when earned. Purchases and sales of investments are recorded on a trade-date basis and realized gains/losses on sales of investments are determined based on the specific identification method.

We recognize investment income from fixed maturities based on the constant effective yield method, which includes an adjustment for estimated principal repayments, if any. The effective yield used to determine the amortization for fixed maturities subject to prepayment risk (e.g. asset-backed, loan-backed and other structured securities) is recalculated and adjusted periodically based upon actual historical and/or projected future cash flows. The adjustments to the yield for highly-rated prepayable fixed maturities are accounted for using the retrospective method. The adjustments to the yield for other prepayable fixed maturities are accounted for using the prospective method.

On a quarterly basis, we assess whether unrealized losses on available for sale investments represent impairments that are other than temporary. Several factors are considered in this assessment including, but not limited to: (i) the extent and duration of the decline, (ii) the reason for the decline (e.g. credit spread widening, credit event), (iii) the historical and implied future volatility of the fair value, (iv) the financial condition and near-term prospects of the issuer and (v) the collateral structure and credit support of the security, if applicable.

Effective April 1, 2009, we adopted an updated Financial Accounting Standards Board (“FASB”) guidance for the recognition and presentation of OTTI for fixed maturities. A fixed maturity is impaired when the fair value is below its amortized cost. For an impaired fixed maturity where we intend to sell the security or it is more likely than not that we will be required to sell the security before its anticipated recovery, the full amount of the impairment is charged to earnings and is included in net realized investment gains (losses). Where we intend to hold the impaired fixed maturity, we estimate the anticipated credit loss of the security and recognize only this portion of the impairment in earnings, with the remaining balance of the impairment (non-credit related e.g. interest rates, market conditions, etc.) recognized in AOCI.

We impair an equity security in an unrealized loss position when we do not have the ability and intent to hold the security for a reasonable period of time to allow for a full recovery. The full impairment is charged to earnings, in net realized investment gains (losses).

Upon recognition of an OTTI, the new cost basis for the security is the previous amortized cost for a fixed maturity or cost for an equity security less the OTTI recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value; except for fixed maturities whereby the difference between the new cost basis and the expected cash flows is accreted on a quarterly basis to net investment income over the remaining life of the fixed maturity.

Other investments

We record other investments at fair value (see Note 6 – Fair Value Measurements), with both changes in fair value and realized gains/losses reported in net investment income.

Short-term investments

Short-term investments primarily comprise highly-liquid debt securities with maturities greater than three months but less than one year from the date of purchase. These investments are carried at amortized cost, which approximates fair value.

b) Cash and cash equivalents

Cash equivalents include money-market funds and fixed interest deposits placed with a maturity of under 90 days when purchased. Cash and cash equivalents are recorded at amortized cost, which approximates fair value due to the short-term, liquid nature of these securities.

c) Premiums and Acquisition Costs

Premiums

Insurance premiums written are recorded in accordance with the terms of the underlying policies. For multi-year policies where premiums are payable in annual installments, premiums are recorded at the inception of the policy based on management's best estimate of total premiums to be received. However, this excludes premiums for the period during which the insured/reinsured has the ability to unilaterally commute or cancel coverage. Reinsurance premiums are recorded at the inception of the policy and are estimated based upon information received from ceding companies. Any subsequent differences arising on insurance and reinsurance premium estimates are recorded in the period they are determined.

(Re)insurance premiums are earned over the period during which we are exposed to the underlying risk, which is generally one to two years with the exception of multi-year policies. Unearned premiums represent the portion of premiums written which is applicable to the unexpired risks under contracts in force.

Reinstatement premiums are recognized at the time a loss event occurs and coverage limits for the remaining life of the contract are reinstated under pre-defined contract terms; such premiums are earned over the remaining risk period. The accrual of reinstatement premiums is based on our estimate of losses and loss adjustment expenses, which reflects management's judgment, as described in Note 2(d) – Losses and Loss Expenses below.

Premiums receivable balances in excess of 90 days past due are reviewed for impairment at least quarterly and an allowance is established for amounts considered uncollectible. The need for charge-off of any amounts previously reserved as uncollectible is assessed on a quarterly basis.

Acquisition Costs

Acquisition costs vary with and are directly related to the acquisition of (re)insurance contracts and consist primarily of fees and commissions paid to brokers and premium taxes. Premiums receivable are presented net of applicable acquisition costs when contract terms provide for the right of offset. Acquisition costs are shown net of commissions earned on ceded reinsurance. Our net acquisition costs are deferred and charged to expense as the related premium is earned.

Anticipated losses and loss expenses, other costs and investment income related to these premiums are considered in assessing the recoverability of our deferred acquisition costs. If deferred amounts are estimated to be unrecoverable, they are expensed. Compensation expenses for personnel involved in contract acquisition, as well as advertising costs, are expensed as incurred.

d) Losses and Loss Expenses

Our reserve for losses and loss expenses represents an estimate of the unpaid portion of our ultimate liability for losses and loss expenses for (re)insured events that have occurred at or before the balance sheet date. The balance reflects both claims that have been reported to us (“case reserves”) and claims that have been incurred but not yet reported to us (“IBNR”). These amounts are reduced for estimated amounts of salvage and subrogation recoveries.

We review our reserve for losses and loss expenses on a quarterly basis. Case reserves are primarily established based on amounts reported from insureds and/or their brokers. Management estimates IBNR after reviewing detailed actuarial analyses and applying informed judgment to consider qualitative factors that may not be fully reflected in the actuarial estimates. A variety of actuarial methods are utilized in this process, including the Expected Loss Ratio, Bornhuetter-Ferguson and Chain Ladder methods. Our estimate is highly dependent on management's judgment as to which method(s) are most appropriate for a particular accident year and class of business. Given our relatively limited operating history, our historical data is often supplemented with industry benchmarks when applying these methodologies.

Any adjustments to our previous reserve for losses and loss expenses estimates are recognized in the period they are determined. While we believe that our reserves for losses and loss expenses are adequate, this estimate requires significant judgment and new information, events or circumstances may result in ultimate losses that are materially greater or less than provided for in the Consolidated Balance Sheets.

e) Reinsurance

In the normal course of business, we purchase reinsurance protection to limit our ultimate losses from catastrophic events and to reduce our loss aggregation risk. The premiums paid to our reinsurers (i.e. premiums ceded) are expensed over the coverage period. Prepaid reinsurance premiums represent the portion of premiums ceded which is applicable to the unexpired term of the contracts in force. Reinstatement-related premiums ceded are recorded at the time a loss event occurs and our coverage limits for the remaining life of a contract are reinstated under pre-defined contract terms; such premiums are expensed over the remaining risk period.

Reinsurance recoverable related to our case reserves is estimated on a case-by-case basis by applying the terms of any applicable reinsurance coverage to our individual case reserve estimates. Our estimate of reinsurance recoverable related to our IBNR reserves is generally developed as part of our loss reserving process.

Our reinsurance recoverable is presented net of a provision for uncollectible amounts, reflecting the amount we believe will ultimately not be recovered due to reinsurer insolvency, contractual disputes over contract language or coverage and/or some other reason. We apply case-specific provisions against certain recoveries that we deem unlikely to be collected in full. In addition, we use a default analysis to estimate our provision for uncollectible amounts on the remainder of the balance.

The estimates of our reinsurance recoverable and the associated provision require management's judgment and are reviewed in detail on a quarterly basis. Any adjustments to amounts recognized in prior periods are reported in our net losses and loss expenses in the Consolidated Statement of Operations for the period when the adjustments were identified. The charge-off of amounts previously reserved as uncollectible is also considered on a case-by-case basis as part of this quarterly process.

f) Foreign Exchange

The Company's reporting currency is the U.S. dollar. In translating the financial statements of our subsidiaries or branches where the functional currency is other than the U.S. dollar, assets and liabilities are converted into U.S. dollars using the rates of exchange in effect at the balance sheet dates and revenues and expenses are converted using the weighted average foreign exchange rates for the period. The effect of translation adjustments is reported as a separate component of AOCI in shareholders' equity.

In recording foreign currency transactions, revenue and expense items are converted to the relevant functional currency at the exchange rate prevailing at the transaction date. Assets and liabilities originating in currencies other than the functional currency are translated into the functional currency at the rates of exchange in effect at the balance sheet date. The resulting foreign currency gains or losses are recognized in the Consolidated Statements of Operations, with the exception of those related to foreign-denominated available for sale investments. For these investments, exchange rate fluctuations represent an unrealized appreciation/depreciation in the value of the securities and are included in the related component of AOCI.

g) Share-Based Compensation

The Company is authorized to issue restricted stock awards and units, stock options and other equity-based awards to its employees and directors. The fair value of the share-based compensation is measured at the grant date and expensed over the period for which the employee is required to provide services in exchange for the award. The expense associated with awards subject to graded vesting is recognized on a straight-line basis. Forfeiture benefits are estimated at the time of grant and incorporated in the determination of share-based compensation.

h) Derivative Instruments

Derivative Instruments not Designated as Hedging Instruments

We may enter into derivative instruments such as futures, options, interest rate swaps and foreign currency forward contracts as part of our overall foreign currency risk management strategy, to obtain exposure to a particular financial market or for yield enhancement. From time to time we may also enter into (re)insurance contracts that meet the FASB's definition of a derivative contract.

We measure all derivative instruments at fair value (see Note 6 – Fair Value Measurements) and recognize them as either assets or liabilities in the Consolidated Balance Sheets. Subsequent changes in fair value and any realized gains or losses are recognized in the Consolidated Statements of Operations.

Derivative Instruments Designated as Hedging Instruments

We may designate a currency derivative as a hedge of foreign exchange rate-related movements in the fair value of certain investment portfolios. This is referred to as a fair value hedge. Changes in the fair value of the designated fair value hedge, along with the changes in the fair value of the hedged asset attributable to the hedged risk, are recorded in net realized investment gains (losses) in the Consolidated Statements of Operations, along with any hedge ineffectiveness.

To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in value of the hedged item. Further, the hedge relationship must be designated and formally documented at the inception, detailing the particular risk management objective and strategy for the hedge, including the item and risk that is being hedged, the derivative that is being used, and how effectiveness will be assessed. We formally measure the hedge effectiveness at inception and on an ongoing basis. We evaluate the effectiveness on a retrospective and prospective basis, using the period-to-period dollar offset method. Using this method, if the hedge correlation is within the range of 80% to 125%, we consider the hedge effective and apply hedge accounting. Cash flows from derivative instruments designated as hedging instruments are presented as operating activities in the Consolidated Statements of Cash Flows.

i) Goodwill and Intangible Assets

We classify intangible assets into three categories: (1) intangible assets with finite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization, and (3) goodwill.

We amortize intangible assets with finite lives over their estimated useful lives in proportion to the estimated economic benefits of the intangible assets. We also test these assets for impairment if circumstances indicate that the carrying value may not be fully recoverable. Such circumstances may include an economic downturn in a geographic market or a change in the assessment of future operations. If, as a result of such an evaluation, we determine that the carrying value of the finite lived intangible assets is not recoverable, the value of the assets will be reduced to fair value with the difference being expensed in the Consolidated Statement of Operations.

Our intangible assets with indefinite lives include licenses held by certain subsidiaries in various jurisdictions that allow such subsidiaries to write insurance and/or reinsurance business. These intangible assets are carried at or below estimated fair value and are tested annually for impairment, or more frequently if circumstances indicate that a possible impairment has arisen.

We have recorded goodwill in connection with certain acquisitions. Goodwill represents the excess of the cost of acquisitions over the fair value of the net assets acquired and is assigned to applicable reporting unit(s) on the acquisition date based upon the expected benefit to be received by the reporting unit. We determine the expected benefit based on several factors, including the purpose of the business combination, our strategy subsequent to the business combination and the structure of the acquired company subsequent to the business combination. Goodwill is not subject to amortization. We test goodwill for potential impairment during the fourth quarter each year and between annual tests if an event occurs or circumstances change that may indicate that potential exists for the fair value of a reporting unit to be reduced to a level below its carrying amount. Our impairment evaluation is a two-step process and is conducted at the reporting unit level. First, we identify potential impairment by comparing the fair value of the reporting units to estimated book values, including goodwill. The fair value of each reporting unit is derived based upon valuation techniques and assumptions that we believe market participants would use to value our business. The estimated fair values are generally determined utilizing methodologies that incorporate discounted cash flow analyses. The values derived from the analyses are then compared to recent market transactions for reasonableness. We derive the net book value of our reporting units by estimating the amount of shareholders' equity required to support the activities of each reporting unit. If the estimated fair value of a reporting unit exceeds the estimated book value, goodwill is not considered impaired. If the book value exceeds the estimated fair value, the second step compares the implied fair value of the reporting unit's goodwill with the carrying amount of the goodwill in order to determine the magnitude of impairment to be recognized. The implied fair value of goodwill is determined by deducting the fair value of a reporting unit's identifiable assets and liabilities from the fair value of the reporting unit as a whole. The excess of the carrying value of goodwill above the implied goodwill, if any, would be recognized as an impairment charge in the Consolidated Statement of Operations.

j) Income Taxes

Certain subsidiaries and branches of the Company operate in jurisdictions where they are subject to taxation. Current and deferred income taxes are charged or credited to net income, or in certain cases to AOCI, based upon enacted tax laws and rates applicable in the relevant jurisdiction in the period in which the tax becomes accruable or realizable. Deferred income taxes are provided for all temporary differences between the bases of assets and liabilities used in the Consolidated Balance Sheets and those used in the various jurisdictional tax returns. When our assessment indicates that it is more likely than not that a portion of a deferred tax asset will not be realized in the foreseeable future, a valuation allowance against deferred tax assets is recorded. We recognize the tax benefits of uncertain tax positions only when the position is more-likely-than-not to be sustained upon audit by the relevant taxing authorities.

k) Treasury Shares

Common shares repurchased by the Company and not subsequently cancelled are classified as treasury shares and are recorded at cost. This results in a reduction of shareholders' equity in the Consolidated Balance Sheets. When shares are reissued from treasury, we use the average cost method to determine the cost of the reissued shares. Gains on sales/reissuances of treasury shares are credited to additional paid-in capital, while losses are charged to additional paid-in capital to the extent that previous net gains from reissued treasury shares were included therein; otherwise losses are charged to retained earnings.

l) New Accounting Standards Adopted in 2011

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

Effective January 1, 2011, we prospectively adopted amended FASB guidance that modified the definition of the types of costs that can be capitalized in relation to the acquisition of new and renewal insurance contracts. The amended guidance requires costs to be incremental or directly related to the successful acquisition of new or renewal contracts in order to be capitalized as a deferred acquisition cost. Capitalized costs would include incremental direct costs, such as commissions paid to brokers. Additionally, the portion of employee salaries and benefits directly related to time spent for acquired contracts would be capitalized. Costs that fall outside the revised definition must be expensed when incurred. In accordance with the transitional provisions of this amended guidance, we elected not to capitalize acquisition costs that we did not previously capitalize, namely those costs related to employee salaries and benefits. The adoption of this guidance did not impact our results of operations, financial condition or liquidity.

Comprehensive Income

Effective July 1, 2011, we retrospectively adopted FASB guidance revising the manner in which entities present comprehensive income in their financial statements. The amended guidance eliminated the option to report other comprehensive income and its components in the statement of changes in shareholders' equity. Components of comprehensive income may be reported in either 1) a continuous statement of comprehensive income or 2) two separate but consecutive statements. As the new guidance did not change the items that constitute net income and/or other comprehensive income, the timing of reclassifications from other comprehensive income to net income or the earnings per share computation, its adoption did not impact our results of operations, financial condition or liquidity.

m) Recently Issued Accounting Policies Not Yet Adopted

Fair Value Measurement and Disclosures

In May 2011, the FASB amended its existing fair value measurement guidance by:

clarifying principal market determination,
addressing the fair value measurement of instruments with offsetting market or counterparty credit risks,
clarifying that the “valuation premise” and “highest and best use” concepts are not relevant to financial instruments,
limiting the application of premiums and discounts,
prohibiting the use of blockage factors to all three levels of the fair value hierarchy, and
expanding disclosure requirements.

If different fair value measurements result from the application of the amended guidance, the difference will be recognized in income in the period of adoption as a change in estimate. The new requirements will be effective January 1, 2012 and the new disclosure requirements are to be applied prospectively. We do not expect that adoption of this amended guidance will significantly impact our results of operations, financial condition or liquidity.

Goodwill

In September 2011, the FASB issued new guidance providing entities with the option to perform a qualitative assessment prior to calculating the estimated fair value of a reporting unit, the first step of the required annual goodwill impairment test. Entities able to qualitatively conclude that the fair value of a reporting unit more likely than not (a likelihood of more than 50%) exceeds its carrying amount can bypass the existing requirement to perform the quantitative annual impairment test. This guidance will become effective at January 1, 2012 and does not change how an entity measures a goodwill impairment loss; thus, the adoption of this guidance will not impact our results of operations, financial condition 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 will be 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 will not impact our results of operations, financial condition or liquidity.
