- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.

| Accounting Policies [Abstract] | |
| Significant Accounting Policies | SIGNIFICANT ACCOUNTING POLICIES There have been no material changes to our significant accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2011. BASIS OF PRESENTATION The consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company's financial position and results of operations as at the end of and for the periods presented. All significant intercompany accounts and transactions have been eliminated from these statements. Except as discussed in “Note 3. Discontinued Operations,” and unless otherwise noted, the notes to the consolidated financial statements reflect the Company's continuing operations. Certain comparative information has been reclassified to conform to the current presentation. Because of the seasonality of the Company's business, the results of operations and cash flows for any interim period will not necessarily be indicative of the results of operations and cash flows for the full fiscal year or subsequent quarters. USE OF ESTIMATES IN FINANCIAL STATEMENTS The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. The major estimates reflected in the Company’s consolidated financial statements include, but are not limited to, the reserve for claims and claim expenses, reinsurance recoverables, including allowances for reinsurance recoverables deemed uncollectible, estimates of written and earned premiums, fair value, including the fair value of investments, financial instruments and derivatives, impairment charges and the Company’s deferred tax valuation allowance. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts In October 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts (“ASU 2010-26”), which amends FASB ASC Topic Financial Services - Insurance. ASU 2010-26 modifies 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. ASU 2010-26 became effective for fiscal periods beginning on or after December 15, 2011, and as a result, the Company adopted ASU 2010-26 effective January 1, 2012. The adoption of ASU 2010-26 did not have a material impact on the Company's consolidated statements of operations and financial condition. Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”), which amends FASB ASC Topic Fair Value Measurement. ASU 2011-04 was issued to provide largely identical guidance about fair value measurement and disclosure requirements with the International Accounting Standards Board's new International Financial Reporting Standards (“IFRS”) 13, Fair Value Measurement. ASU 2011-04 does not extend the use of fair value but, rather, provides guidance about how fair value should be applied where it is already required or permitted under GAAP and requires enhanced disclosures covering all transfers between Levels 1 and 2 of the fair value hierarchy. Additional disclosures covering Level 3 assets are also required. ASU 2011-04 became effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and as a result, the Company adopted ASU 2011-04 effective January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on the Company's consolidated statements of operations and financial condition. The additional disclosures required by ASU 2011-04 have been provided in "Note 5. Fair Value Measurements" of the Company's Notes to Consolidated Financial Statements. Presentation of Comprehensive Income In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (“ASU 2011-05”), which amends FASB ASC Topic Comprehensive Income. ASU 2011-05 increases the prominence of items reported in other comprehensive income and eliminates the option to present components of other comprehensive income as part of the statement of changes in shareholders' equity. ASU 2011-05 requires that all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 became effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with retroactive application required. The Company adopted ASU 2010-26 effective January 1, 2012 and it did not have a material impact on the Company's consolidated statements of operations and financial condition. |

| Discontinued Operation, Income (Loss) from Discontinued Operation Disclosures [Abstract] | |
| Discontinued Operations | DISCONTINUED OPERATIONS U.S.-Based Insurance Operations On November 18, 2010, the Company entered into a Stock Purchase Agreement with QBE to sell substantially all of its U.S.-based insurance operations, including its U.S. property and casualty business underwritten through managing general agents, its crop insurance business underwritten through Agro National, its commercial property insurance operations and its claims operations. At December 31, 2010, the Company classified the assets and liabilities associated with this transaction as held for sale and the assets and liabilities were recorded at the lower of the carrying value or fair value less costs to sell. The financial results for these operations have been presented as discontinued operations in the Company's consolidated statements of operations for all periods presented. Consideration for the transaction was book value at December 31, 2010, for the aforementioned businesses, payable in cash at closing and subject to adjustment for certain tax and other items. The transaction closed on March 4, 2011 and net consideration of $269.5 million was received by the Company. Pursuant to the Stock Purchase Agreement, the Company was subject to a post-closing review following December 31, 2011 of the net reserve for claims and claim expenses for loss events occurring on or prior to December 31, 2010 (the “Reserve Collar”). Subsequent to the post-closing review, the Company was liable to pay, or otherwise reimburse QBE amounts up to $10.0 million for net adverse development on prior accident years net claims and claim expenses. Conversely, if prior accident years net claims and claim expenses experienced net favorable development, QBE was liable to pay, or otherwise reimburse the Company amounts up to $10.0 million. During 2011, the Company recognized a $10.0 million liability and corresponding expense in liabilities of discontinued operations held for sale and (loss) income from discontinued operations, respectively, due to purported net adverse development on prior accident years net claims and claim expenses associated with the Reserve Collar. Effective May 23, 2012, the Company and QBE reached an agreement in respect of the Reserve Collar, and the Company paid QBE the sum of $9.0 million on June 1, 2012, representing full and final settlement of the Reserve Collar and recorded a gain of $1.0 million in income from discontinued operations during the second quarter of 2012. |

| Investments | INVESTMENTS Fixed Maturity Investments Trading The following table summarizes the fair value of fixed maturity investments trading:
Fixed Maturity Investments Available For Sale The following table summarizes the amortized cost, fair value and related unrealized gains and losses and non-credit other-than-temporary impairments of fixed maturity investments available for sale:
Contractual maturities of fixed maturity investments are as follows. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
Equity Investments Trading The following table summarizes the fair value of equity investments trading:
Pledged Investments At June 30, 2012, $1,330.9 million of cash and investments at fair value were on deposit with, or in trust accounts for the benefit of various counterparties, including with respect to the Company's principal letter of credit facility. Of this amount, $522.6 million is on deposit with, or in trust accounts for the benefit of, U.S. state regulatory authorities. Net Investment Income, Net Realized and Unrealized Gains on Investments and Net Other-Than-Temporary Impairments The components of net investment income are as follows:
Net realized and unrealized gains on investments and net other-than-temporary impairments are as follows:
The following table provides an analysis of the length of time the Company’s fixed maturity investments available for sale in an unrealized loss have been in a continual unrealized loss position.
At June 30, 2012, the Company held 44 fixed maturity investments available for sale securities that were in an unrealized loss position, including 13 fixed maturity investments available for sale securities that were in an unrealized loss position for twelve months or greater. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before the anticipated recovery of the remaining amortized cost basis. The Company performed reviews of its fixed maturity investments available for sale for the six months ended June 30, 2012 and 2011, respectively, in order to determine whether declines in the fair value below the amortized cost basis were considered other-than-temporary in accordance with the applicable guidance, as discussed below. Other-Than-Temporary Impairment Process The Company's process for assessing whether declines in the fair value of its fixed maturity investments available for sale represent impairments that are other-than-temporary includes reviewing each fixed maturity investment available for sale that is impaired and determining: (i) if the Company has the intent to sell the debt security or (ii) if it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery; and (iii) whether a credit loss exists, that is, where the Company expects that the present value of the cash flows expected to be collected from the security are less than the amortized cost basis of the security. In assessing the Company’s intent to sell securities, the Company’s procedures may include actions such as discussing planned sales with its third party investment managers, reviewing sales that have occurred shortly after the balance sheet date, and consideration of other qualitative factors that may be indicative of the Company’s intent to sell or hold the relevant securities. For the six months ended June 30, 2012, the Company recognized $Nil other-than-temporary impairments due to the Company’s intent to sell these securities as of June 30, 2012 (2011 – $Nil). In assessing whether it is more likely than not that the Company will be required to sell a security before its anticipated recovery, the Company considers various factors including its future cash flow forecasts and requirements, legal and regulatory requirements, the level of its cash, cash equivalents, short term investments, fixed maturity investments trading and fixed maturity investments available for sale in an unrealized gain position, and other relevant factors. For the six months ended June 30, 2012, the Company recognized $Nil of other-than-temporary impairments due to required sales (2011 – $Nil). In evaluating credit losses, the Company considers a variety of factors in the assessment of a security including: (i) the time period during which there has been a significant decline below cost; (ii) the extent of the decline below cost and par; (iii) the potential for the security to recover in value; (iv) an analysis of the financial condition of the issuer; (v) the rating of the issuer; (vi) the implied rating of the issuer based on an analysis of option adjusted spreads; (vii) the absolute level of the option adjusted spread for the issuer; and (viii) an analysis of the collateral structure and credit support of the security, if applicable. Once the Company determines that it is possible that a credit loss may exist for a security, the Company performs a detailed review of the cash flows expected to be collected from the issuer. The Company estimates expected cash flows by applying estimated default probabilities and recovery rates to the contractual cash flows of the issuer, with such default and recovery rates reflecting long-term historical averages adjusted to reflect current credit, economic and market conditions, giving due consideration to collateral and credit support, if applicable, and discounting the expected cash flows at the purchase yield on the security. In instances in which a determination is made that an impairment exists but the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining amortized cost basis, the impairment is separated into: (i) the amount of the total other-than-temporary impairment related to the credit loss; and (ii) the amount of the total other-than-temporary impairment related to all other factors. The amount of the other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the other-than-temporary impairment related to all other factors is recognized in other comprehensive income. For the six months ended June 30, 2012, the Company recognized $0.3 million of other-than-temporary impairments which were recognized in earnings and $52 thousand related to other factors which were recognized in other comprehensive income (2011 – $Nil and $Nil, respectively). The following table provides a rollforward of the amount of other-than-temporary impairments related to credit losses recognized in earnings for which a portion of an other-than-temporary impairment was recognized in accumulated other comprehensive income:

| Fair Value Measurements | FAIR VALUE MEASUREMENTS The use of fair value to measure certain assets and liabilities with resulting unrealized gains or losses is pervasive within the Company's financial statements. Fair value is defined under accounting guidance currently applicable to the Company to be the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. The Company recognizes the change in unrealized gains and losses arising from changes in fair value in its consolidated statements of operations, with the exception of changes in unrealized gains and losses on its fixed maturity investments available for sale, which are recognized as a component of accumulated other comprehensive income in shareholders' equity. FASB ASC Topic Fair Value Measurements and Disclosures prescribes a fair value hierarchy that prioritizes the inputs to the respective valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement of the asset or liability. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and the Company considers factors specific to the asset or liability. In order to determine if a market is active or inactive for a security, the Company considers a number of factors, including, but not limited to, the spread between what a seller is asking for a security and what a buyer is bidding for the same security, the volume of trading activity for the security in question, the price of the security compared to its par value (for fixed maturity investments), and other factors that may be indicative of market activity. There have been no material changes in the Company's valuation techniques, nor have there been any transfers between Level 1 and Level 2, or Level 2 and Level 3, respectively, during the period represented by these consolidated financial statements. Below is a summary of the assets and liabilities that are measured at fair value on a recurring basis and also represents the carrying amount on the Company’s consolidated balance sheet:
(1) See "Note 12. Derivative Instruments" for additional information related to the fair value by type of contract, of derivatives entered into by the Company.
(1) See "Note 12. Derivative Instruments" for additional information related to the fair value by type of contract, of derivatives entered into by the Company. Level 1 and Level 2 Assets and Liabilities Measured at Fair Value Fixed Maturity Investments Fixed maturity investments included in Level 1 consist of the Company's investments in U.S. treasuries. Fixed maturity investments included in Level 2 are agencies, non-U.S. government, Federal Deposit Insurance Company ("FDIC") guaranteed corporate, non-U.S. government-backed corporate, corporate, agency mortgage-backed, non-agency mortgage-backed, commercial mortgage-backed and asset-backed fixed maturity investments. The Company’s fixed maturity investments portfolios are primarily priced using pricing services, such as index providers and pricing vendors, as well as broker quotations. In general, the pricing vendors provide pricing for a high volume of liquid securities that are actively traded. For securities that do not trade on an exchange, the pricing services generally utilize market data and other observable inputs in matrix pricing models to determine month end prices. Observable inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, bids, offers, reference data and industry and economic events. Index pricing generally relies on market traders as the primary source for pricing, however models are also utilized to provide prices for all index eligible securities. The models use a variety of observable inputs such as benchmark yields, transactional data, dealer runs, broker-dealer quotes and corporate actions. Prices are generally verified using third party data. Securities which are priced by an index provider are generally included in the index. In general, broker-dealers value securities through their trading desks based on observable inputs. The methodologies include mapping securities based on trade data, bids or offers, observed spreads, and performance on newly issued securities. Broker-dealers also determine valuations by observing secondary trading of similar securities. Prices obtained from broker quotations are considered non-binding, however they are based on observable inputs and by observing secondary trading of similar securities obtained from active, non-distressed markets. The Company considers these Level 2 inputs as they are corroborated with other market observable inputs. The techniques generally used to determine the fair value of our fixed maturity investments are detailed below by asset class. U.S. treasuries Level 1 - At June 30, 2012, the Company’s U.S. treasuries fixed maturity investments are primarily priced by pricing services and had a weighted average effective yield of 0.5% and a weighted average credit quality of AA (December 31, 2011 - 0.6% and AA, respectively). When pricing these securities, the pricing services utilize daily data from many real time market sources, including active broker dealers. Certain data sources are regularly reviewed for accuracy to attempt to ensure the most reliable price source is used for each issue and maturity date. Agencies Level 2 - At June 30, 2012, the Company’s agency fixed maturity investments had a weighted average effective yield of 0.7% and a weighted average credit quality of AA (December 31, 2011 - 0.5% and AA, respectively). The issuers of the Company’s agency fixed maturity investments primarily consist of the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and other agencies. Fixed maturity investments included in agencies are primarily priced by pricing services. When evaluating these securities, the pricing services gather information from market sources and integrates other observations from markets and sector news. Evaluations are updated by obtaining broker dealer quotes and other market information including actual trade volumes, when available. The fair value of each security is individually computed using analytical models which incorporate option adjusted spreads and other daily interest rate data. Non-U.S. government (Sovereign debt) Level 2 - Non-U.S. government fixed maturity investments held by the Company at June 30, 2012, had a weighted average effective yield of 2.2% and a weighted average credit quality of AA (December 31, 2011 - 2.3% and AA, respectively). The issuers of securities in this sector are non-U.S. governments and their respective agencies as well as supranational organizations. Securities held in these sectors are primarily priced by pricing services who employ proprietary discounted cash flow models to value the securities. Key quantitative inputs for these models are daily observed benchmark curves for treasury, swap and high issuance credits. The pricing services then apply a credit spread for each security which is developed by in-depth and real time market analysis. For securities in which trade volume is low, the pricing services utilize data from more frequently traded securities with similar attributes. These models may also be supplemented by daily market and credit research for international markets. FDIC guaranteed corporate Level 2 - The Company’s FDIC guaranteed corporate fixed maturity investments had a weighted average effective yield of 0.3% and a weighted average credit quality of AA at June 30, 2012 (December 31, 2011 - 0.3% and AA, respectively). The issuers consist of well known corporate issuers who participate in the FDIC program. The Company’s FDIC guaranteed corporate fixed maturity investments are primarily priced by pricing services. When evaluating these securities, the pricing services gather information from market sources regarding the issuer of the security and obtain credit data, as well as other observations, from markets and sector news. Evaluations are updated by obtaining broker dealer quotes and other market information including actual trade volumes, when available. The pricing services also consider the specific terms and conditions of the securities, including any specific features which may influence risk. In certain instances, securities are individually evaluated using a spread which is added to the U.S. treasury curve. Non-U.S. government-backed corporate Level 2 - Non-U.S. government-backed corporate fixed maturity investments had a weighted average effective yield of 1.2% and a weighted average credit quality of AAA at June 30, 2012 (December 31, 2011 - 1.4% and AAA, respectively). Non-U.S. government-backed fixed maturity investments are primarily priced by pricing services who employ proprietary discounted cash flow models to value the securities. Key quantitative inputs for these models are daily observed benchmark curves for treasury, swap and high issuance credits. The pricing services then apply a credit spread to the respective curve for each security which is developed by in-depth and real time market analysis. For securities in which trade volume is low, the pricing services utilize data from more frequently traded securities with similar attributes. These models may also be supplemented by daily market and credit research for international markets. Corporate Level 2 - At June 30, 2012, the Company’s corporate fixed maturity investments principally consist of U.S. and international corporations and had a weighted average effective yield of 3.1% and a weighted average credit quality of A (December 31, 2011 - 4.2% and A, respectively). The Company’s corporate fixed maturity investments are primarily priced by pricing services. When evaluating these securities, the pricing services gather information from market sources regarding the issuer of the security and obtain credit data, as well as other observations, from markets and sector news. Evaluations are updated by obtaining broker dealer quotes and other market information including actual trade volumes, when available. The pricing services also consider the specific terms and conditions of the securities, including any specific features which may influence risk. In certain instances, securities are individually evaluated using a spread which is added to the U.S. treasury curve or a security specific swap curve as appropriate. Agency mortgage-backed Level 2 - At June 30, 2012, the Company’s agency mortgage-backed fixed maturity investments included agency residential mortgage-backed securities with a weighted average effective yield of 1.5%, a weighted average credit quality of AA and a weighted average life of 2.8 years (December 31, 2011 - 1.5%, AA and 2.6 years, respectively). The Company’s agency mortgage-backed fixed maturity investments are primarily priced by pricing services using a mortgage pool specific model which utilizes daily inputs from the active and the to be announced ("TBA") market which is very liquid, as well as the U.S. treasury market. The model also utilizes additional information, such as the weighted average maturity, weighted average coupon and other available pool level data which is provided by the sponsoring agency. Valuations are also corroborated with daily active market quotes. Non-agency mortgage-backed Level 2 - The Company’s non-agency mortgage-backed fixed maturity investments include non-agency prime residential mortgage-backed and non-agency Alt-A fixed maturity investments. The Company has no fixed maturity investments classified as sub-prime held in its fixed maturity investments portfolio. At June 30, 2012, the Company’s non-agency prime residential mortgage-backed fixed maturity investments have a weighted average effective yield of 5.2%, a weighted average credit quality of BBB, and a weighted average life of 5.2 years (December 31, 2011 - 8.0%, BBB and 3.3 years, respectively). The Company’s non-agency Alt-A fixed maturity investments held at June 30, 2012 have a weighted average effective yield of 7.0%, a weighted average credit quality of BBB and a weighted average life of 5.5 years (December 31, 2011 - 9.1%, A and 3.8 years, respectively) . Securities held in these sectors are primarily priced by pricing services using an option adjusted spread (”OAS”) model or other relevant models, which principally utilize inputs including benchmark yields, available trade information or broker quotes, and issuer spreads. The pricing services also review collateral prepayment speeds, loss severity and delinquencies among other collateral performance indicators for the securities valuation, when applicable. Commercial mortgage-backed Level 2 - The Company’s commercial mortgage-backed fixed maturity investments held at June 30, 2012 have a weighted average effective yield of 2.5%, a weighted average credit quality of AA, and a weighted average life of 3.8 years (December 31, 2011 - 3.2%, AA and 4.2 years, respectively). Securities held in these sectors are primarily priced by pricing services. The pricing services apply dealer quotes and other available trade information such as bid and offers, prepayment speeds which may be adjusted for the underlying collateral or current price data, the U.S. treasury curve and swap curve as well as cash settlement. The pricing services discount the expected cash flows for each security held in this sector using a spread adjusted benchmark yield based on the characteristics of the security. Asset-backed Level 2 - At June 30, 2012, the Company’s asset-backed fixed maturity investments had a weighted average effective yield of 2.5%, a weighted average credit quality of AAA and a weighted average life of 3.8 years (December 31, 2011 - 0.9%, AAA and 1.8 years, respectively). The underlying collateral for the Company’s asset-backed fixed maturity investments primarily consists of student loans, credit card receivables, auto loans and other receivables. Securities held in these sectors are primarily priced by pricing services. The pricing services apply dealer quotes and other available trade information such as bids and offers, prepayment speeds which may be adjusted for the underlying collateral or current price data, the U.S. treasury curve and swap curve as well as cash settlement. The pricing services determine the expected cash flows for each security held in this sector using historical prepayment and default projections for the underlying collateral and current market data. In addition, a spread is applied to the relevant benchmark and used to discount the cash flows noted above to determine the fair value of the securities held in this sector. Short Term Investments Level 2 - The fair value of the Company's portfolio of short term investments are generally determined using amortized cost which approximates fair value and, in certain cases, in a manner similar to the Company’s fixed maturity investments noted above. Equity Investments, Classified as Trading Level 1 - The fair value of the Company's portfolio of equity investments, classified as trading are primarily priced by pricing services, reflecting the closing price quoted for the final trading day of the period. When pricing these securities, the pricing services utilize daily data from many real time market sources, including active broker dealers and applicable securities exchanges. All data sources are regularly reviewed for accuracy to attempt to ensure the most reliable price source is used for each issue. Other investments Senior secured bank loan funds Level 2 - At June 30, 2012, the Company’s investments in senior secured bank loan funds include funds that invest primarily in bank loans and other senior debt instruments. The fair value of the Company’s senior secured bank loan funds are determined using the net asset value per share of the funds. Investments of $246.6 million are redeemable, in part on a monthly basis, or in whole over a three month period. Catastrophe bonds Level 2 - The Company's other investments include investments in catastrophe bonds which are recorded at fair value. The fair value of the Company's investments in catastrophe bonds is based on broker or underwriter bid indications. Non-U.S. fixed income funds Level 2 - The Company’s non-U.S. fixed income funds invested primarily in non-U.S. convertible securities. The fair values of the investments in this category were estimated using the net asset value per share of the investments which were provided by third parties such as the relevant investment manager or administrator. During April 2012, the Company fully redeemed its remaining investment in non-U.S. fixed income funds at the then net asset value per share. Hedge funds Level 2 - The Company has investments in hedge funds that pursue multiple strategies. The fair values of the Company’s hedge funds are determined by adjusting the previous period's reported net asset value, which is generally one month in arrears, for an estimated periodic rate of return obtained from the respective investment manager. For each respective hedge fund investment, the Company obtains and reviews the valuation methodology used by the investment manager and the latest audited financial statements to attempt to ensure that the hedge fund investment is following fair value principles consistent with GAAP in determining the net asset value of each investor's interest. During June 2012, the Company fully redeemed the portion of its investment in hedge funds which the Company had considered Level 2 in the fair value hierarchy, at the then net asset value per share. Other assets and liabilities Derivatives Level 1 and Level 2 - Other assets and liabilities include certain other derivatives entered into by the Company. The fair value of these transactions include certain exchange traded foreign currency forward contracts which are considered Level 1, and certain credit derivatives, determined using standard industry valuation models and considered Level 2, as the inputs to the valuation model are based on observable market inputs, including credit spreads, credit ratings of the underlying referenced security, the risk free rate and the contract term. Other Level 1 - The liabilities measured at fair value and included in Level 1 at June 30, 2012 of $4.6 million are principally cash settled restricted stock units (“CSRSU”) that form part of the Company's compensation program. The fair value of the Company's CSRSUs is determined using observable exchange traded prices for the Company's common shares. Level 3 Assets and Liabilities Measured at Fair Value Below is a summary of quantitative information regarding the significant observable and unobservable inputs (Level 3) used in determining the fair value of assets and liabilities measured at fair value on a recurring basis:
Fixed Maturity Investments Corporate Level 3 - Included in the Company's corporate fixed maturity investments is an investment with a fair value of $17.5 million in the preferred equity of a property and casualty insurance group organized to market residential property insurance in North America. The Company measures the fair value of this investment using a DCF model and seeks to incorporate all relevant information reasonably available to it. The Company considers the contractual agreement which stipulates the methodology for calculating a dividend rate to be paid upon liquidation, conversion or redemption. At June 30, 2012, the dividend rate was 5.9%. In addition, the Company has estimated an illiquidity premium of 1.0% and a risk-free rate of 0.2%. To ensure the estimate for fair value determined using the DCF model is reasonable, the Company reviews private market comparables of similar investments, if available, and in particular, credit ratings of other private market comparables for similar investments to determine the appropriateness of its estimate of fair value using a DCF model. The fair value of the Company's investment in corporate fixed maturity investments determined by a DCF model is positively correlated to the dividend rate, and inversely correlated to the credit spread, illiquidity premium and the risk-free rate. In addition, the Company's corporate fixed maturity investments include an investment with a fair value of $10.3 million at June 30, 2012 in the preferred equity of a company that provides insurance for a variety of veterinarian costs, including surgeries, medication and diagnostic testing. When utilizing an internal valuation model to determine the fair value of this investment, the Company uses a combination of quantitative and qualitative factors, which may include, but are not limited to, discounted cash flow analysis, financial statement analysis, budgets and forecasts, capital transactions and third party valuations. In circumstances where a private market transaction has recently occurred, the Company will evaluate the comparableness of that transaction and incorporate into its internal valuation model accordingly. Recent private market transactions of investments similar to that held by the Company have been used to determine the fair value of $10.3 million at June 30, 2012, as the Company believes it represents the price that would be received upon the sale of its investment in an orderly transaction among market participants. Consequently, should future relevant private market transactions occur, the Company will re-evaluate the information available used to determine fair value of this investment and record any adjustments to fair value in its consolidated statements of operations. Other investments Private equity partnerships Level 3 - Included in the Company’s $360.3 million of investments in private equity partnerships at June 30, 2012 are alternative asset limited partnerships (or similar corporate structures) that invest in certain private equity asset classes including U.S. and global leveraged buyouts; mezzanine investments; distressed securities; real estate; and oil, gas and power. The fair value of private equity partnership investments is based on current estimated net asset values established in accordance with the governing documents of such investments and is obtained from the investment manager or general partner of the respective entity. The type of underlying investments held by the investee which form the basis of the net asset valuation include assets such as private business ventures, for which the Company does not have access to financial information. As a result, the Company is unable to corroborate the fair value measurement of the underlying investments of the private equity partnership and therefore requires significant management judgment to determine the fair value of the private equity partnership. In circumstances where there is a reporting lag between the current period end reporting date and the reporting date of the latest fund valuation, the Company estimates the fair value of these funds by starting with the prior month or quarter-end fund valuations, adjusting these valuations for actual capital calls, redemptions or distributions, as well as the impact of changes in foreign currency exchange rates, and then estimating the return for the current period. In circumstances in which the Company estimates the return for the current period, all relevant information reasonably available to the Company is utilized. This principally includes preliminary estimates reported to the Company by its fund managers, obtaining the valuation of underlying portfolio investments where such underlying investments are publicly traded and therefore have a readily observable price, using information that is available to the Company with respect to the underlying investments, reviewing various indices for similar investments or asset classes, as well as estimating returns based on the results of similar types of investments for which the Company has obtained reported results, or other valuation methods, where possible. The range of such current estimated periodic returns for the six months ended June 30, 2012 was negative 19.7% to positive 12.6% with a weighted average of negative 1.4%. The fair value of the Company's investment in private equity partnerships is positively correlated to the estimated periodic rate of return. The Company also considers factors such as recent financial information, the value of capital transactions with the partnership and management’s judgment regarding whether any adjustments should be made to the net asset value. For each respective private equity partnership, the Company obtains and reviews the valuation methodology used by the investment manager or general partner and the latest audited financial statements to ensure that the investment partnership is following fair value principles consistent with GAAP in determining the net asset value of each limited partner's interest. Senior secured bank loan funds Level 3 - The Company has a $22.7 million investment in a closed end fund which invests primarily in loans. The Company has no right to redeem its investment in this fund. The Company’s investment in this fund is valued using estimated monthly net asset valuations received from the investment manager. The lock up provisions in this fund result in a lack of current observable market transactions between the fund participants and the fund, and therefore, the Company considers the fair value of its investment in this fund to be determined using Level 3 inputs. The Company obtains and reviews the latest audited financial statements to attempt to ensure that the fund is following fair value principles consistent with GAAP in determining the net asset value. Hedge funds Level 3 - The Company has $6.2 million of hedge fund investments that are invested in so called "side pockets" or illiquid investments. In these instances, the Company generally does not have the right to redeem its interest, and as such, the Company classifies this portion of its investment as Level 3. The fair value of these illiquid investments are determined by adjusting the previous periods' reported net asset value (generally one month in arrears) for an estimated periodic rate of return obtained from the respective investment manager. For each respective hedge fund investment, the Company obtains and reviews the valuation methodology used by the investment manager and the latest audited financial statements to ensure that the hedge fund investment is following fair value principles consistent with GAAP in determining the net asset value. Miscellaneous other investments Level 3 - Included in miscellaneous other investments is a loan to a third party with a fair value of $1.3 million. The Company determines the fair value of this loan using a DCF model and endeavors to incorporate all relevant information reasonably available, including the outstanding principal amount, interest rate inherent in the loan as determined using the 3-month LIBOR, credit spread and an illiquidity premium. The fair value of this loan is inversely correlated to the 3-month LIBOR, credit spread and illiquidity premium. Other assets and liabilities Assumed and ceded (re)insurance contracts Level 3 - The $9.7 million fair value of the Company's assumed and ceded (re)insurance contracts accounted for at fair value is obtained through the use of an internal valuation model with the inputs to the internal valuation model based on proprietary data as observable market inputs are not available. The most significant unobservable inputs are the reserve for claims and claim expenses and losses recoverable. Generally, an increase (decrease) in the reserve for claims and claim expenses, or a decrease (increase) in losses recoverable, would result in a decrease (increase) to the fair value of the Company's assumed and ceded (re)insurance contracts. Derivatives Level 3 - Derivatives measured at fair value include $9.1 million of proprietary, non-exchange traded derivative-based risk management products primarily to address weather and energy risks, and hedging and trading activities related to these risks. The trading markets for these derivatives are generally linked to energy and agriculture commodities, weather and other natural phenomena and in instances where market prices are not available, the Company uses industry or internally developed valuation techniques such as spread option, Black Scholes, quanto and simulation modeling to determine fair value and are considered Level 3. These models may reference prices for similar instruments. Observable and unobservable inputs to these valuation techniques vary by contract requirements and commodity type, are validated using market-based or independently sourced parameters where applicable and would typically include the following, if applicable, dependent on contract requirements and commodity type:
The range of each unobservable input could vary based on the specific commodity, including, but not limited to natural gas, electricity, crude, liquids, temperature or precipitation. Due to the diversity of the portfolio, the range of unobservable inputs could be wide-spread as reflected in the above table on quantitative information. If a trade has one or more significant valuation inputs that are unobservable, such trades are initially valued at the transaction price, which is considered to be the best initial estimate of fair value. Subsequent to the initial valuation, the Company updates market observable inputs to reflect observable market changes. The unobservable inputs are validated at each reporting period and are only changed when corroborated by evidence such as similar market transactions, third-party pricing services and/or broker or dealer quotations or other empirical market data. The Company seeks to use broker quotes in less liquid markets. Changes in any or all of the unobservable inputs listed above may contribute positively or negatively to the overall portfolio fair value depending upon the underlying position. In general, movements in weather curves are the largest contributing factor that impact fair value. However, trades valued using unobservable inputs represent a small percentage of the total number of transactions in the portfolio. Pricing models are internally approved by the Company's Risk Committee prior to implementation and are reviewed periodically. Other Level 3 - The Company has an investment of $14.2 million at June 30, 2012 in the common equity of a mortgage insurance company which provides private capital to lenders and investors that supports financing for homeowner mortgages. The fair value of this investment is based on the unadjusted net asset value obtained from the management of the mortgage insurance company. The fair value of the Company's investment is positively correlated to the net asset valuation. The Company also considers factors such as recent financial information, the value of capital transactions with the mortgage insurance company and management's judgment regarding whether any adjustments should be made to the net asset value. The Company also has an investment in the preferred equity of a company that develops online risk management products primarily focused on motor fuels risk, more specifically, structuring products, sourcing the risk and facilitating the settlement of capital. The fair value of this investment at June 30, 2012 of $1.3 million was determined using recent private market transactions. In instances where private market transactions are not available, the fair value is measured using a number of qualitative and quantitative factors, including but not limited to a net asset estimation of the company, projected earnings, private market transactions, and any other information that may be available to the Company. At June 30, 2012, the Company determined that the fair value of its investment was appropriate when compared to the net asset position of the company and recent private market transactions. Should the net asset position of the company increase, the fair value of the Company's investment would also increase. Below is a reconciliation of the beginning and ending balances, for the periods shown, of assets and liabilities measured at fair value on a recurring basis using Level 3 inputs. Interest and dividend income are included in net investment income and are excluded from the reconciliation.
Financial Instruments Disclosed, But Not Carried, at Fair Value The Company uses various financial instruments in the normal course of its business. The Company's insurance contracts are excluded from fair value of financial instruments accounting guidance, unless the Company elects the fair value option, and therefore, are not included in the amounts discussed herein. The carrying values of cash, accrued interest, receivables for investments sold, certain other assets, payables for investments purchased, certain other liabilities, and other financial instruments not included herein approximated their fair values. Senior Notes In January 2003, RenaissanceRe issued $100.0 million, which represents the carrying amount on the Company’s consolidated balance sheet, of 5.875% Senior Notes due February 15, 2013, with interest on the notes payable on February 15 and August 15 of each year. At June 30, 2012, the fair value of the 5.875% Senior Notes was $102.2 million (December 31, 2011 – $103.4 million). In March 2010, RenRe North America Holdings Inc. (“RRNAH”) issued $250.0 million of 5.75% Senior Notes due March 15, 2020, with interest on the notes payable on March 15 and September 15 of each year. At June 30, 2012, the fair value of the 5.75% Senior Notes was $264.1 million (December 31, 2011 - $263.0 million). The fair value of RenaissanceRe’s 5.875% Senior Notes and RRNAH’s 5.75% Senior Notes is determined using indicative market pricing obtained from third-party service providers, which the Company considers Level 2 in the fair value hierarchy. There have been no changes during the period in the Company's valuation technique used to determine the fair value of its Senior Notes. The Fair Value Option for Financial Assets and Financial Liabilities The Company has elected to account for certain assets and liabilities at fair value using the guidance under FASB ASC Topic Financial Instruments as the Company believes it represents the most meaningful measurement basis for these assets and liabilities. Below is a summary of the balances the Company has elected to account for at fair value:
Included in net investment income for the three and six months ended June 30, 2012 was net unrealized (losses) gains of $(13.4) million and $21.9 million related to the changes in fair value of other investments (2011 – $5.7 million and $33.7 million, respectively). Net unrealized losses related to the changes in the fair value of other assets and liabilities recorded in other (loss) income was $0.4 million and $2.5 million for the three and six months ended June 30, 2012 (2011 – $(0.8) million and $43.3 million, respectively). Measuring the Fair Value of Other Investments Using Net Asset Valuations The table below shows the Company’s portfolio of other investments measured using net asset valuations:
Private equity partnerships – Included in the Company’s investments in private equity partnerships are alternative asset limited partnerships (or similar corporate structures) that invest in certain private equity asset classes including U.S. and global leveraged buyouts; mezzanine investments; distressed securities; real estate; and oil, gas and power. The fair values of the investments in this category have been estimated using the net asset value of the investments, as discussed in detail above. The Company generally has no right to redeem its interest in any of these private equity partnerships in advance of dissolution of the applicable partnership. Instead, the nature of these investments is that distributions are received by the Company in connection with the liquidation of the underlying assets of the applicable limited partnership. It is estimated that the majority of the underlying assets of the limited partnerships would liquidate over 7 to 10 years from inception of the limited partnership. Senior secured bank loan funds – The Company’s investment in senior secured bank loan funds includes funds that invest primarily in bank loans and other senior debt instruments. The fair values of the investments in this category have been determined using the net asset value per share of the funds or the estimated net asset per share where applicable, as discussed in detail above. Investments of $246.6 million are redeemable, in part on a monthly basis, or in whole over a three month period. The Company also has a $22.7 million investment in a closed end fund which invests in loans. The Company has no right to redeem its investment in this fund. Hedge funds – The Company invests in hedge funds that pursue multiple strategies. The fair values of the investments in this category are estimated using the net asset value per share of the funds, as discussed in detail above. The remaining portion of the Company's investments in hedge funds at June 30, 2012, are $6.2 million of so called “side pocket” investments which are not redeemable at the option of the shareholder. As noted above, the Company fully redeemed the remaining non-side pocket investments in hedge funds during June 2012. The Company has retained its interest in the side pocket investments until the underlying investments attributable to such side pockets are liquidated, realized or deemed realized at the discretion of the fund manager. |

| Ceded Reinsurance | CEDED REINSURANCE The Company purchases reinsurance and other protection to manage its risk portfolio and to reduce its exposure to large losses. The Company currently has in place contracts that provide for recovery of a portion of certain claims and claim expenses, generally in excess of various retentions or on a proportional basis. In addition to loss recoveries, certain of the Company’s ceded reinsurance contracts provide for recoveries of additional premiums, reinstatement premiums and for lost no-claims bonuses, which are incurred when losses are ceded to other reinsurance contracts. The Company remains liable to the extent that any reinsurance company fails to meet its obligations.

| Noncontrolling Interests | NONCONTROLLING INTERESTS Redeemable Noncontrolling Interest – DaVinciRe In October 2001, the Company formed DaVinciRe and DaVinci with other equity investors. RenaissanceRe owns a noncontrolling economic interest in DaVinciRe; however, because RenaissanceRe controls a majority of DaVinciRe’s outstanding voting rights, the consolidated financial statements of DaVinciRe are included in the consolidated financial statements of the Company. The portion of DaVinciRe’s earnings owned by third parties is recorded in the consolidated statements of operations as net (income) loss attributable to noncontrolling interests. The Company's ownership in DaVinciRe was 31.5% at June 30, 2012 (December 31, 2011 - 42.8%). DaVinciRe shareholders are party to a shareholders agreement (the “Shareholders Agreement”) which provides DaVinciRe shareholders, excluding RenaissanceRe, with certain redemption rights that enable each shareholder to notify DaVinciRe of such shareholder’s desire for DaVinciRe to repurchase up to half of such shareholder’s initial aggregate number of shares held, subject to certain limitations, such as limiting the aggregate of all share repurchase requests to 25% of DaVinciRe’s capital in any given year and satisfying all applicable regulatory requirements. If total shareholder requests exceed 25% of DaVinciRe’s capital, the number of shares repurchased will be reduced among the requesting shareholders pro-rata, based on the amounts desired to be repurchased. Shareholders desiring to have DaVinci repurchase their shares must notify DaVinciRe before March 1 of each year. The repurchase price will be based on GAAP book value as of the end of the year in which the shareholder notice is given, and the repurchase will be effective as of such date. Payment will be made by April 1 of the following year, following delivery of the audited financial statements for the year in which the repurchase was effective. The repurchase price is subject to a true-up for development on outstanding loss reserves after settlement of all claims relating to the applicable years. Certain third party shareholders of DaVinciRe submitted repurchase notices on or before the required annual redemption notice date of March 1, 2011, in accordance with the Shareholders Agreement. The repurchase notices submitted on or before March 1, 2011, were for shares of DaVinciRe with a GAAP book value of $9.2 million at December 31, 2011. Effective January 1, 2012, DaVinciRe redeemed the shares for $9.2 million, less a $1.8 million reserve holdback. On June 1, 2011, DaVinciRe completed an equity raise of $100.0 million from new and existing shareholders, including $30.0 million contributed by the Company. As a result of the equity raise, the Company's ownership in DaVinciRe decreased to 42.8% effective June 1, 2011. Effective January 1, 2012, an existing third party shareholder sold a portion of its shares in DaVinciRe to a new third party shareholder. In connection with the sale by the existing third party shareholder, DaVinciRe retained a $4.9 million holdback. In addition, effective January 1, 2012, the Company sold a portion of its shares of DaVinciRe to a separate new third party shareholder. The Company sold these shares for $98.9 million, net of a $10.0 million reserve holdback due from DaVinciRe. The Company's ownership in DaVinciRe was 42.8% at December 31, 2011 and subsequent to the above transactions, its ownership interest in DaVinciRe decreased to 34.7% effective January 1, 2012. Certain third party shareholders of DaVinciRe submitted repurchase notices on or before the required annual redemption notice date of March 1, 2012, in accordance with the Shareholders Agreement. The repurchase notices submitted on or before March 1, 2012, were for shares of DaVinciRe with a GAAP book value of $50.0 million at June 30, 2012. On June 1, 2012, DaVinciRe completed an equity raise of $49.3 million from a new third party investor. In addition, the Company and an existing third party investor each sold $24.7 million in common shares of DaVinciRe to another existing third party investor, for a total of $49.4 million. In connection with the sale by the Company and the existing third party investor, DaVinciRe retained a $5.0 million holdback, $2.5 million of which is payable to the Company. As a result of the above transactions, the Company's ownership in DaVinciRe decreased to 31.5% effective January 1, 2012. The Company expects its ownership in DaVinciRe to fluctuate over time. The activity in redeemable noncontrolling interest – DaVinciRe is detailed in the table below:
Noncontrolling Interest - Angus Fund L.P. (the “Angus Fund”) In December 2010, REAL and RenRe Commodity Advisors Inc. (“RRCA”), both wholly owned subsidiaries of the Company, formed the Angus Fund with other equity investors. REAL, the general partner of the Angus Fund, has invested $55 thousand in the Angus Fund, representing a 1.0% ownership interest at June 30, 2012 (December 31, 2011 - $41 thousand and 1.0%, respectively), and RRCA, a limited partner, has invested $2.0 million in the Angus Fund, representing a 35.1% ownership interest at June 30, 2012 (December 31, 2011 - $1.0 million and 24.2%, respectively). The Angus Fund was formed to provide capital to and make investments in companies primarily in the heating oil and propane distribution industries to supplement the Company’s weather and energy risk management operations. The Angus Fund meets the definition of a variable interest entity ("VIE"), therefore the Company evaluated its ownership in the Angus Fund to determine if it is the primary beneficiary. The Company has concluded it is the primary beneficiary of the Angus Fund as it has the power to direct, and has a more than insignificant economic interest in, the activities of the Angus Fund and as such, the financial position and results of operations of the Angus Fund are consolidated. The portion of the Angus Fund's earnings owned by third parties is recorded in the consolidated statements of operations as net (income) loss attributable to noncontrolling interest. The Company expects its ownership in the Angus Fund to fluctuate over time. The activity in noncontrolling interest is detailed in the table below:

| Variable Interest Entities | VARIABLE INTEREST ENTITIES Effective January 1, 2012, the Company formed and launched a new managed joint venture, Upsilon Reinsurance Ltd. (“Upsilon Re”), a Bermuda domiciled special purpose insurer ("SPI"), to provide additional capacity to the worldwide aggregate and per-occurrence retrocessional property catastrophe excess of loss market for the 2012 underwriting year. The original business was written by Renaissance Reinsurance of Europe ("ROE"), a wholly owned subsidiary of RenaissanceRe, and included $37.4 million of gross premiums written. A portion of this business was in turn ceded to Upsilon Re under a fully-collateralized retrocessional reinsurance contract, effective January 1, 2012. In conjunction with the formation and launch of Upsilon Re, $16.8 million of non-voting Class B shares were sold to external investors, and the Company invested $48.8 million in Upsilon Re's non-voting Class B shares, representing a 74.5% ownership interest in Upsilon Re. The Class B shareholders will participate in substantially all of the profits or losses of Upsilon Re while the Class B shares remain outstanding. The holders of Class B shares indemnify Upsilon Re against losses relating to insurance risk and therefore these shares have been accounted for as prospective reinsurance under Financial Accounting Standards Board Accounting Standards Codification Topic Financial Services - Insurance. In addition, another third party investor supplied $17.6 million of capital through a reinsurance participation with ROE alongside Upsilon Re. Inclusive of the third party quota share agreement, the Company has a 61.4% participation in the original risks assumed by ROE. Both Upsilon Re and the third party reinsurance participation related to Upsilon Re are managed by RUM in return for an expense override, as well as a potential underwriting profit commission. Upsilon Re is considered a VIE and the Company is considered the primary beneficiary. As a result, Upsilon Re is consolidated by the Company and all significant inter-company transactions have been eliminated. The Company's ownership interest in Upsilon Re could change over time, perhaps materially so, and the Company may also elect to underwrite additional risks within Upsilon Re and to write business within Upsilon Re in future underwriting years. Effective June 1, 2012, the Company formed and launched a new managed joint venture, Timicuan Reinsurance III Limited (“Tim Re III”), a Bermuda domiciled SPI, to provide collateralized reinsurance in respect of a portfolio of Florida reinstatement premium protection ("RPP") contracts. The original business was written by Renaissance Reinsurance and DaVinci, and included $41.1 million of gross premiums written incepting June 1, 2012 and Renaissance Reinsurance and DaVinci ceded $37.7 million to Tim Re III under a fully-collateralized reinsurance contract. In conjunction with the formation and launch of Tim Re III, $44.8 million of non-voting Class B shares were sold to external investors, and the Company invested an additional $10.3 million in Tim Re III's non-voting Class B shares, representing an 18.6% ownership interest in Tim Re III. The Class B shareholders will participate in substantially all of the profits or losses of Tim Re III while the Class B shares remain outstanding. The holders of Class B shares indemnify Tim Re III against losses relating to insurance risk and therefore these shares have been accounted for as prospective reinsurance under Financial Accounting Standards Board Accounting Standards Codification Topic Financial Services - Insurance. In addition, another third party investor supplied $5.2 million of capital through a reinsurance participation with Renaissance Reinsurance and DaVinci, alongside Tim Re III. Both Tim Re III and the third party reinsurance participation related to Tim Re III are managed by RUM in return for a potential underwriting profit commission. Tim Re III is considered a VIE and the Company is considered the primary beneficiary. As a result, Tim Re III is consolidated by the Company and all significant inter-company transactions have been eliminated. |

| Stockholders' Equity Note [Abstract] | |
| Shareholders' Equity | SHAREHOLDERS’ EQUITY The Board of Directors of RenaissanceRe declared, and RenaissanceRe paid, a dividend of $0.27 per common share to shareholders of record on March 15 and June 15, 2012, respectively. The Company’s share repurchase program may be effected from time to time, depending on market conditions and other factors, through open market purchases and privately negotiated transactions. Unless terminated earlier by resolution of the Company’s Board of Directors, the program will expire when the Company has repurchased the full value of the shares authorized. The Company’s decision to repurchase common shares will depend on, among other matters, the market price of the common shares and the capital requirements of the Company. During the six months ended June 30, 2012, the Company repurchased 1.2 million shares in open market transactions, at an aggregate cost of $91.6 million, and at an average share price of $74.57. Subsequent to June 30, 2012 and through the period ending July 30, 2012, the Company repurchased approximately 71 thousand common shares in open market transactions at an aggregate cost of $5.3 million and at an average share price of $74.21. On February 22, 2012, the Company approved an increase in its authorized share repurchase program to an aggregate amount of $500.0 million. At June 30, 2012, $412.0 million remained available for repurchase under the Board authorized share repurchase program. See "Part II, Item 2 - Unregistered Sales of Equity Securities and use of Proceeds" for additional information. In December 2006, the Company raised $300.0 million through the issuance of 12 million Series D Preference Shares at $25 per share and in March 2004, the Company raised $250.0 million through the issuance of 10 million Series C Preference Shares at $25 per share. The Series D and Series C Preference Shares may be redeemed at $25 per share at the Company’s option on or after December 1, 2011 and March 23, 2009, respectively. Dividends on the Series D and Series C Preference Shares are cumulative from the date of original issuance and are payable quarterly in arrears at 6.60% and 6.08%, respectively, when, if, and as declared by the Board of Directors. The preference shares have no stated maturity and are not convertible into any other securities of the Company. Generally, the preference shares have no voting rights. Whenever dividends payable on the preference shares are in arrears (whether or not such dividends have been earned or declared) in an amount equivalent to dividends for six full dividend periods (whether or not consecutive), the holders of the preference shares, voting as a single class regardless of class or series, will have the right to elect two directors to the Board of Directors of the Company. During the six months ended June 30, 2012, the Company declared and paid $17.5 million in preference share dividends (2011 – $17.5 million). |

| Derivative Instruments | DERIVATIVE INSTRUMENTS The Company enters into derivative instruments such as futures, options, swaps, forward contracts and other derivative contracts primarily to manage its foreign currency exposure, obtain exposure to a particular financial market, for yield enhancement, or for trading and speculation. The Company accounts for its derivatives in accordance with FASB ASC Topic Derivatives and Hedging, which requires all derivatives to be recorded at fair value on the Company's balance sheet as either assets or liabilities, depending on the rights or obligations of the derivatives, with changes in fair value reflected in current earnings. The Company does not currently apply hedge accounting in respect of any positions reflected in its consolidated financial statements. Where the Company has entered into master netting agreements with counterparties, or the Company has the legal and contractual right to offset positions, the derivative positions are generally netted by counterparty and are reported accordingly in other assets and other liabilities. The table below shows the location on the consolidated balance sheets and fair value of the Company’s principal derivative instruments:
The location and amount of the gain (loss) recognized in the Company’s consolidated statements of operations related to its derivative instruments is shown in the following table:
The Company is not aware of the existence of any credit-risk related contingent features that it believes would be triggered in its derivative instruments that are in a net liability position at June 30, 2012. Interest Rate Futures The Company uses interest rate futures within its portfolio of fixed maturity investments to manage its exposure to interest rate risk, which can include increasing or decreasing its exposure to this risk. At June 30, 2012, the Company had $360.2 million of notional long positions and $303.7 million of notional short positions of primarily Eurodollar, U.S. treasury and non-U.S. dollar futures contracts (December 31, 2011 – $3.2 billion and $285.7 million, respectively). The fair value of these derivatives is determined using exchange traded prices. Foreign Currency Derivatives The Company’s functional currency is the U.S. dollar. The Company writes a portion of its business in currencies other than U.S. dollars and may, from time to time, experience foreign exchange gains and losses in the Company’s consolidated financial statements. All changes in exchange rates, with the exception of non-U.S. dollar denominated investments classified as available for sale and non-monetary assets and liabilities, are recognized currently in the Company’s consolidated statements of operations. Underwriting Operations Related Foreign Currency Contracts The Company’s foreign currency policy with regard to its underwriting operations is generally to hold foreign currency assets, including cash, investments and receivables that approximate the foreign currency liabilities, including claims and claim expense reserves and reinsurance balances payable. When necessary, the Company may use foreign currency forward and option contracts to minimize the effect of fluctuating foreign currencies on the value of non-U.S. dollar denominated assets and liabilities associated with its underwriting operations. The fair value of the Company's underwriting operations related foreign currency contracts is determined using indicative pricing obtained from counterparties or broker quotes. At June 30, 2012, the Company had outstanding underwriting related foreign currency contracts of $179.7 million in notional long positions and $503.4 million notional in short positions, denominated in U.S. dollars (December 31, 2011 – $160.5 million and $700.8 million, respectively). Investment Portfolio Related Foreign Currency Forward Contracts The Company’s investment operations are exposed to currency fluctuations through its investments in non-U.S. dollar fixed maturity investments, short term investments and other investments. To economically hedge its exposure to currency fluctuations from these investments, the Company has entered into foreign currency forward contracts. Foreign exchange gains (losses) associated with the Company’s hedging of these non-U.S. dollar investments are recorded in net foreign exchange (losses) gains in its consolidated statements of operations. The fair value of the Company's investment portfolio related foreign currency forward contracts is determined using an interpolated rate based on closing forward market rates. At June 30, 2012, the Company had outstanding investment portfolio related foreign currency contracts of $198.3 million in notional long positions and $284.6 million in notional short positions, denominated in U.S. dollars (December 31, 2011 – $48.1 million and $211.6 million, respectively). Energy and Risk Operations Related Foreign Currency Contracts The Company’s energy and risk operations are exposed to currency fluctuations through certain derivative transactions it enters into that are denominated in non-U.S. dollars. The Company may, from time to time, use foreign currency forward and option contracts to minimize the effect of fluctuating foreign currencies on the value of non-U.S. dollar denominated assets and liabilities associated with these operations. The fair value of the Company's energy and risk operations related foreign currency contracts is based on exchange traded prices. At June 30, 2012, the Company’s energy and risk operations had foreign currency contracts of $Nil in notional long positions and $16.7 million in notional short positions (December 31, 2011 – $7.8 million and $12.7 million, respectively). Credit Derivatives The Company’s exposure to credit risk is primarily due to its fixed maturity investments, short term investments, premiums receivable and reinsurance recoverable. From time to time, the Company purchases credit derivatives to hedge its exposures in the insurance industry, and to assist in managing the credit risk associated with ceded reinsurance. The Company also employs credit derivatives in its investment portfolio to either assume credit risk or hedge its credit exposure. The fair value of the credit derivatives is determined using industry valuation models, broker bid indications or internal pricing valuation techniques. The fair value of these credit derivatives can change based on a variety of factors including changes in credit spreads, default rates and recovery rates, the correlation of credit risk between the referenced credit and the counterparty, and market rate inputs such as interest rates. At June 30, 2012, the Company had outstanding credit derivatives of $15.0 million in notional long positions and $24.4 million in notional short positions, denominated in U.S. dollars (December 31, 2011 – $15.0 million and $38.1 million, respectively). Energy and Weather-Related Derivatives The Company regularly transacts in certain derivative-based risk management products primarily to address weather and energy risks and engages in hedging and trading activities related to these risks. The trading markets for these derivatives are generally linked to energy and agriculture commodities, weather and other natural phenomena. Currently, a percentage of the Company’s derivative-based risk management products are transacted on a dual-trigger basis combining weather or other natural phenomenon, with prices for commodities or securities related to energy or agriculture. The fair value of these contracts is obtained through the use of quoted market prices, or in the absence of such quoted prices, industry or internal valuation models. Generally, the Company’s current portfolio of such derivative contracts is of comparably short duration and such contracts are predominantly seasonal in nature. Over time, the Company currently expects that its participation in these markets, and the impact of these operations on its financial results, is likely to increase on both an absolute and relative basis. As of the dates set forth below, the Company had the following gross derivative contract positions outstanding relating to its energy and weather derivatives trading activities.
The Company uses, among other things, value-at-risk (“VaR”) analysis to monitor the risks associated with its energy and weather derivatives trading portfolio. VaR is a tool that measures the potential loss that could occur if the Company's trading positions were maintained over a defined period of time, calculated at a given statistical confidence level. Due to the seasonal nature of the Company's energy and weather derivatives trading activities, the VaR is based on a rolling two season (one-year) holding period assuming no dynamic trading during the holding period. A 99% confidence level is used for the VaR analysis. A 99% confidence level implies that within a one-year period, the potential loss in the Company's portfolio is not expected to exceed the VaR estimate in 99% of the possible modeled outcomes. In the remaining estimated 1% of the possible outcomes, the anticipated potential loss is expected to be higher than the VaR figure, and on average substantially higher. The VaR model, based on a Monte Carlo simulation methodology, seeks to take into account correlations between different positions and potential for movements to offset one another within the portfolio. The expected value of the risk factors in the Company's portfolio is generally obtained from exchange-traded futures markets. For most of the risk factors, the volatility is derived from exchange-traded options markets. For those risk factors for which exchange-traded options might not exist, the volatility is based on historical analysis matched to broker quotes from the over-the-counter market, where available. The joint distribution of outcomes is based on our estimate of the historical seasonal dependence among the underlying risk factors, scaled to the current market levels. The Company then estimates the expected outcomes by applying a Monte Carlo simulation to these risk factors. The joint distribution of the simulated risk factors is then filtered through the portfolio positions, and then the distribution of the outcomes is realized. The 99th percentile of this distribution is then calculated as the portfolio VaR. Among the significant limitations of this methodology is that the market data used to forecast parameters of the model may not be an appropriate proxy of those parameters. The VaR methodology uses a number of assumptions, such as (i) risks are measured under average market conditions, assuming normal distribution of market risk factors, (ii) future movements in market risk factors follow estimated historical movements, and (iii) the assessed exposures do not change during the holding period. We believe the VaR methodology has utility but do not derive absolute assurance from it. Accordingly, there is no guarantee that these assumptions will prove correct and actual outcomes may vary, perhaps substantially and adversely. The Company expects that, for any given period, its actual results will differ from its assumptions, including with respect to previously estimated potential losses and that such losses could be substantially higher than the estimated VaR. At June 30, 2012, the estimated VaR for the Company's portfolio of energy and weather-related derivatives, as described above, calculated at an estimated 99% confidence level, was $42.0 million. The average, low and high amounts calculated by the Company's VaR analysis during the six months ended June 30, 2012 were $26.4 million, $13.0 million and $49.3 million, respectively. At June 30, 2012, RenaissanceRe had provided guarantees in the aggregate amount of $354.3 million to certain counterparties of the weather and energy risk operations of Renaissance Trading. In the future, RenaissanceRe may issue guarantees for other purposes or increase the amount of guarantees issued to counterparties of Renaissance Trading. Platinum Warrant The Company held a warrant to purchase up to 2.5 million common shares of Platinum for $27.00 per share. The Company recorded its investment in the Platinum warrant at fair value. The fair value of the warrant was estimated using either the Black-Scholes option pricing model or the in-the-money value, the greater of which the Company considered the best estimate of the exit value of the warrant. On January 20, 2011, the Company sold its warrant to Platinum for an aggregate of $47.9 million, and recognized a $3.0 million gain on the sale, which is included in other income during the six months ended June 30, 2011. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Litigation | COMMITMENTS AND CONTINGENCIES There are no material changes from the commitments and contingencies previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2011. The Company and its subsidiaries are subject to lawsuits and regulatory actions in the normal course of business that do not arise from or directly relate to claims on reinsurance treaties or contracts or direct surplus lines insurance policies. This category of business litigation may involve allegations of underwriting or claims-handling errors or misconduct, employment claims, regulatory actions or disputes arising from the Company's business ventures. The Company's operating subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages. Generally, the Company's direct surplus lines insurance operations are subject to greater frequency and diversity of claims and claims-related litigation than its reinsurance operations and, in some jurisdictions, may be subject to direct actions by allegedly injured persons or entities seeking damages from policyholders. These lawsuits, involving claims on policies issued by the Company's subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in its loss and loss expense reserves which are discussed in its loss reserves discussion. In addition, the Company may from time to time engage in litigation or arbitration related to its claims for payment in respect of ceded reinsurance. Any such litigation or arbitration contains an element of uncertainty, and the Company believes the inherent uncertainty in such matters may have increased recently and will likely continue to increase. Currently, the Company believes that no individual litigation or arbitration to which it is presently a party is likely to have a material adverse effect on its financial condition, business or operations. |

|||||||||||||
| Accounting Policies [Abstract] | |||||||||||||
| Basis of Presentation | The consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company's financial position and results of operations as at the end of and for the periods presented. All significant intercompany accounts and transactions have been eliminated from these statements. Except as discussed in “Note 3. Discontinued Operations,” and unless otherwise noted, the notes to the consolidated financial statements reflect the Company's continuing operations. Certain comparative information has been reclassified to conform to the current presentation. Because of the seasonality of the Company's business, the results of operations and cash flows for any interim period will not necessarily be indicative of the results of operations and cash flows for the full fiscal year or subsequent quarters. |
||||||||||||
| Use of Estimates in Financial Statements | The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. The major estimates reflected in the Company’s consolidated financial statements include, but are not limited to, the reserve for claims and claim expenses, reinsurance recoverables, including allowances for reinsurance recoverables deemed uncollectible, estimates of written and earned premiums, fair value, including the fair value of investments, financial instruments and derivatives, impairment charges and the Company’s deferred tax valuation allowance. |
||||||||||||
| Earnings Per Share | The Company accounts for its earnings per share in accordance with FASB ASC Topic Earnings per Share. Basic earnings per common share is based on weighted average common shares and excludes any dilutive effects of stock options and restricted stock. Diluted earnings per common share assumes the exercise of all dilutive stock options and restricted stock grants. In accordance with FASB ASC Topic Earnings per Share, earnings per share calculations use average common shares outstanding - basic, when the Company is in a net loss position for the period. |
||||||||||||
| Recently Adopted Accounting Pronouncements | RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts In October 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts (“ASU 2010-26”), which amends FASB ASC Topic Financial Services - Insurance. ASU 2010-26 modifies 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. ASU 2010-26 became effective for fiscal periods beginning on or after December 15, 2011, and as a result, the Company adopted ASU 2010-26 effective January 1, 2012. The adoption of ASU 2010-26 did not have a material impact on the Company's consolidated statements of operations and financial condition. Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”), which amends FASB ASC Topic Fair Value Measurement. ASU 2011-04 was issued to provide largely identical guidance about fair value measurement and disclosure requirements with the International Accounting Standards Board's new International Financial Reporting Standards (“IFRS”) 13, Fair Value Measurement. ASU 2011-04 does not extend the use of fair value but, rather, provides guidance about how fair value should be applied where it is already required or permitted under GAAP and requires enhanced disclosures covering all transfers between Levels 1 and 2 of the fair value hierarchy. Additional disclosures covering Level 3 assets are also required. ASU 2011-04 became effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and as a result, the Company adopted ASU 2011-04 effective January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on the Company's consolidated statements of operations and financial condition. The additional disclosures required by ASU 2011-04 have been provided in "Note 5. Fair Value Measurements" of the Company's Notes to Consolidated Financial Statements. Presentation of Comprehensive Income In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (“ASU 2011-05”), which amends FASB ASC Topic Comprehensive Income. ASU 2011-05 increases the prominence of items reported in other comprehensive income and eliminates the option to present components of other comprehensive income as part of the statement of changes in shareholders' equity. ASU 2011-05 requires that all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 became effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with retroactive application required. The Company adopted ASU 2010-26 effective January 1, 2012 and it did not have a material impact on the Company's consolidated statements of operations and financial condition. |

| Fair Value | The use of fair value to measure certain assets and liabilities with resulting unrealized gains or losses is pervasive within the Company's financial statements. Fair value is defined under accounting guidance currently applicable to the Company to be the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. The Company recognizes the change in unrealized gains and losses arising from changes in fair value in its consolidated statements of operations, with the exception of changes in unrealized gains and losses on its fixed maturity investments available for sale, which are recognized as a component of accumulated other comprehensive income in shareholders' equity. FASB ASC Topic Fair Value Measurements and Disclosures prescribes a fair value hierarchy that prioritizes the inputs to the respective valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement of the asset or liability. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and the Company considers factors specific to the asset or liability. In order to determine if a market is active or inactive for a security, the Company considers a number of factors, including, but not limited to, the spread between what a seller is asking for a security and what a buyer is bidding for the same security, the volume of trading activity for the security in question, the price of the security compared to its par value (for fixed maturity investments), and other factors that may be indicative of market activity. There have been no material changes in the Company's valuation techniques, nor have there been any transfers between Level 1 and Level 2, or Level 2 and Level 3, respectively, during the period represented by these consolidated financial statements. |

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

The net amount paid (received) by the reporting entity through acquisition (sale/maturities) of short-term investments with an original maturity that is one year or less which qualify for treatment as an investing activity based on management's intention and intended by management to be liquidated, if necessary, within the current operating cycle.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).
