Accounting Policies [Abstract]
Significant accounting policies	The following is a summary of the significant accounting and reporting policies adopted by the Company:
	Use of estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The major estimates reflected in the Company’s condensed consolidated financial statements include, but are not limited to, the loss and loss adjustment expense reserves, estimates of written and earned premiums and fair value of financial instruments.
	Cash and restricted cash and cash equivalents
	Cash and cash equivalents consist of cash held in banks and other short-term, highly liquid investments with original maturity dates of ninety days or less.
	Restricted cash and cash equivalents consist of cash held in trust accounts with the Catastrophe Reinsurer, securing collateralized reinsurance contracts written, trust accounts securing obligations under certain reinsurance contracts and cash held with banks securing letters of credit issued under credit facilities.
	Premium revenue recognition
	To the extent that the amount of written premium is estimable, the Company estimates the ultimate premiums for the entire contract period and records this estimate at the inception of the contract. For contracts where the full written premium is not estimable at inception, the Company records written premium for the portion of the contract period for which the amount is estimable. These estimates are based primarily on information in the underlying contracts as well as information provided by clients and/or brokers.
	Changes in premium estimates are expected and may result in adjustments in any reporting period. These estimates change over time as additional information regarding the underlying business volume is obtained. Any subsequent adjustments arising on such estimates are recorded in the period in which they are determined.
	Premiums written are earned over the exposure period in proportion to the period of risk covered. Unearned premiums represent the portion of premiums written that relate to the remaining term of the underlying policies in force.
	Premiums for retroactive exposures in reinsurance contracts are earned at the inception of the contract, as all of the underlying loss events covered by these exposures occurred in the past. Any underwriting profit at inception related to retroactive exposures in a reinsurance contract is deferred and recognised over the estimated future payout of the loss and loss adjustment expense reserves. Any underwriting loss at inception related to retroactive exposures in a reinsurance contract is recognised immediately.
	Reinsurance premiums ceded
	From time to time the Company reduces the risk of losses on business written by reinsuring certain risks and exposures with other reinsurers. The Company remains liable to the extent that any retrocessionaire fails to meet its obligations and to the extent that the Company does not hold sufficient security for their unpaid obligations. Ceded premiums are written during the period in which the risks incept and are expensed over the contract period in proportion to the period of risk covered. Unearned premiums ceded consist of the unexpired portion of reinsurance ceded.
	Deferred acquisition costs
	Acquisition costs consist of commissions, brokerage and excise taxes that are related directly to the successful acquisition of new or renewal reinsurance contracts. These costs are deferred and amortized over the period in which the related premiums are earned. The Company evaluates the recoverability of deferred acquisition costs by determining if the sum of future earned premiums and anticipated investment income is greater than expected future loss and loss adjustment expenses and acquisition costs. If a loss is probable on the unexpired portion of contracts in force, a premium deficiency loss is recognized. As of March 31, 2015, deferred acquisition costs are considered to be fully recoverable and no premium deficiency has been recorded.
	Acquisition costs also include profit commissions that are expensed when incurred. Profit commissions are calculated and accrued based on the expected loss experience for contracts and recorded when the current loss estimate indicates that a profit commission is probable under the contract terms.
	Loss and loss adjustment expense reserves
	The Company’s loss and loss adjustment expense reserves include case reserves, reserves for losses incurred but not yet reported (“IBNR reserves”) and deferred profit reserves for retroactive exposures in reinsurance contracts. Case reserves are established for losses that have been reported, but not yet paid. IBNR reserves represent the estimated loss and loss adjustment expenses that have been incurred by insureds and reinsureds but not yet reported to the insurer or reinsurer, including unknown future development on loss and loss adjustment expenses that are known to the insurer or reinsurer. IBNR reserves are established by management based on actuarially determined estimates of ultimate loss and loss adjustment expenses.
	Inherent in the estimate of ultimate loss and loss adjustment expenses are expected trends in claim severity and frequency and other factors that may vary significantly as claims are settled. Accordingly, ultimate loss and loss adjustment expenses may differ materially from the amounts recorded in the condensed consolidated financial statements. These estimates are reviewed regularly and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Such adjustments, if any, are recorded in the condensed consolidated statements of income in the period in which they become known.
	Deposit liabilities
	Certain contracts do not transfer sufficient insurance risk to be deemed reinsurance contracts and are accounted for using the deposit method of accounting. Management exercises judgment in determining whether contracts transfer sufficient risk to be accounted for as reinsurance contracts. Using the deposit method of accounting, a deposit liability, rather than written premium, is initially recorded based upon the consideration received less any explicitly identified premiums or fees. In subsequent periods, the deposit liability is adjusted by calculating the effective yield on the deposit to reflect actual payments to date and future expected payments.
	Fair value measurement
	The Company determines the fair value of financial instruments in accordance with current accounting guidance, which defines fair value and establishes a three level fair value hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. Fair value is defined as the price that the Company would receive to sell an asset or would pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Company determines the estimated fair value of each individual security utilizing the highest level inputs available.
	The fair value of the Company’s assets and liabilities, which qualify as financial instruments, approximates the carrying amounts presented in the condensed consolidated balance sheets.
	Investments
	The Company’s investments are classified as “trading securities” and are carried at fair value with changes in fair value included in earnings in the condensed consolidated statements of income.
	The fair value of the Company’s investments are based on quoted market prices, or when such prices are not available, by reference to broker or underwriter bid indications, industry recognized pricing vendors, and/or internal pricing valuation techniques. Investment transactions are recorded on a trade date basis with balances pending settlement included in due to/from brokers in the condensed consolidated balance sheets.
	Realized gains and losses are determined using cost calculated on a specific identification basis. Dividends are recorded on the ex-dividend date. Income and expense are recorded on the accrual basis including interest and premiums amortized and discounts accreted.
	Derivatives
	Underwriting
	The Catastrophe Reinsurer enters into certain contracts under which the potential loss payments are triggered exclusively by reference to a specified index, such as an industry loss. These contracts are considered derivatives. The Company records the fair value of these contracts in derivative liabilities, at fair value, in the condensed consolidated balance sheet. Changes in the fair value of these contracts are recorded in net investment income in the condensed consolidated statement of income.
	Investments
	Derivative instruments within our investment assets managed by our investment manager Third Point LLC, are recorded in the condensed consolidated balance sheets at fair value, with changes in fair values and realized gains and losses recognised in net investment income in the condensed consolidated statements of income.
	Derivatives serve as a key component of the Company’s investment strategy and are utilized primarily to structure the portfolio, or individual investments, and to economically match the investment objectives of the Company. The Company’s derivatives do not qualify as hedges for financial reporting purposes and are recorded in the condensed consolidated balance sheets on a gross basis and not offset against any collateral pledged or received. Pursuant to the International Swaps and Derivatives Association (“ISDA”) master agreements, securities lending agreements and other derivatives agreements, the Company and its counterparties typically have the ability to net certain payments owed to each other in specified circumstances. In addition, in the event a party to one of the ISDA master agreements, securities lending agreements or other derivatives agreements defaults, or a transaction is otherwise subject to termination, the non-defaulting party generally has the right to set off against payments owed to the defaulting party or collateral held by the non defaulting party.
	The Company enters into derivative contracts to manage credit risk, interest rate risk, currency exchange risk, and other exposure risks. The Company uses derivatives in connection with its risk-management activities to economically hedge certain risks and to gain exposure to certain investments. The utilization of derivative contracts also allows for an efficient means by which to trade certain asset classes.
	Fair values of derivatives are determined by using quoted market prices, industry recognized pricing vendors, and counterparty quotes when available; otherwise fair values are based on pricing models that consider the time value of money, volatility, and the current market and contractual prices of underlying financial instruments.
	Embedded derivatives
	Certain of the Company’s deposit and reinsurance contracts contain interest crediting features that vary based on the net investment return on investments managed by Third Point LLC. These contractual features are considered embedded derivatives in accordance with U.S. GAAP. We include the estimated fair value of these embedded derivatives in the condensed consolidated balance sheets with the host contract in order to reflect the expected settlement of these features with the host contract.
	Share-based compensation
	The Company accounts for its share-based compensation transactions using the fair value of the award at the grant date. Determining the fair value of share purchase options at the grant date requires estimation and judgment. The Company uses an option-pricing model (Black-Scholes) to calculate the fair value of share purchase options.
	For share purchase options or restricted share awards granted that contain both a service and performance condition, the Company recognizes share compensation expense only for the portion of the options or restricted share awards that are considered probable of vesting. Share compensation for share purchase options or restricted share awards considered probable of vesting is expensed over the service (vesting) period on a graded vesting basis. The probability of share purchase options or restricted share awards vesting is evaluated at each reporting period.  When the share purchase options or restricted share awards are considered probable of vesting, the Company records a true up of share compensation expense from the grant date (service inception date) to the current reporting period end based on the fair value of the options or restricted share awards at the grant date.
	The Company measures grant date fair value for restricted share awards, with a service condition only, based on the price of its common shares at the grant date and the expense is recognised on a straight-line basis over the vesting period.
	Warrants
	The Company accounts for warrant contracts issued to certain of its founding investors (“Founders”) in conjunction with the initial capitalization of the Company by using either the physical settlement or net-share settlement methods. The fair value of these warrants was recorded in equity as additional paid-in capital. The fair value of warrants issued are estimated on the grant date using the Black-Scholes option-pricing model.
	The Company accounts for certain warrant contracts issued to an advisor, where services have been received by the Company, in part, in exchange for equity instruments, based on the fair value of such services. The associated cost of these warrants has been recorded as capital raise costs and is included in additional paid in capital in the condensed consolidated statements of shareholders’ equity.
	Debt offering costs
	Costs incurred in issuing debt, which includes underwriters’ fees, legal and accounting fees, printing and other fees are capitalized and presented as a direct deduction from the senior notes payable in the condensed consolidated balance sheets. These costs are amortized over the term of the debt and are included in interest expense in the condensed consolidated statements of income.
	Foreign currency transactions
	The Company’s functional currency is the U.S. dollar. Transactions involving monetary assets and liabilities denominated in foreign currencies have been converted into U.S. dollars at the exchange rate in effect on the balance sheet date, and the related revenues and expenses are converted using specific rates for the period, as appropriate. Net foreign currency transaction gains and losses arising from these activities are reported in the condensed consolidated statements of income in the period in which they arise.
	The Company does not isolate the portion of the net investment income resulting from changes in foreign exchange rates on investments, dividends and interest from the fluctuations arising from changes in fair values of securities and derivatives held. Periodic payments received or paid on swap agreements are recorded as realized gain or loss on investment transactions. Such fluctuations are included within net investment income in the condensed consolidated statements of income.
	Income taxes
	We provide for income taxes for our operations in income tax paying jurisdictions. Our provision relies on estimates and interpretations of currently enacted tax laws. We recognize deferred tax assets and liabilities based on the temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Such temporary differences are primarily due to tax basis discounts on loss and loss adjustment expense reserves and unearned premiums, deferred acquisition costs and investments. A valuation allowance against deferred tax assets is recorded if it is more likely than not that all, or some portion, of the benefits related to deferred tax assets will not be realized. Any adjustments to deferred income taxes are accounted for as changes in estimates and are reflected in the condensed consolidated statements of income in the period in which they are made. Any adjustments could be material and could significantly impact earnings in the period they are recorded.
	Non-controlling interests
	The Company consolidates the results of entities in which it has a controlling financial interest. The Company records the portion of shareholders’ equity attributable to non-controlling interests as a separate line within shareholders’ equity in the condensed consolidated balance sheets. The Company records the portion of income attributable to non-controlling interests as a separate line within the condensed consolidated statements of income.
	Earnings per share
	Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the period. The weighted average number of common shares excludes any dilutive effect of outstanding warrants, options and convertible securities such as unvested restricted shares. Diluted earnings per share is based on the weighted average number of common shares and share equivalents including any dilutive effects of warrants, options and other awards under share plans and are determined using the treasury stock method. U.S. GAAP requires that unvested share awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid (referred to as “participating securities”), be included in the number of shares outstanding for both basic and diluted earnings per share calculations. The Company treats certain of its unvested restricted shares as participating securities. In the event of a net loss, the participating securities are excluded from the calculation of both basic and diluted loss per share.
	Leases
	Leases in which substantially all of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are recognised in the condensed consolidated statements of income on a straight-line basis over the term of the lease.
	Comprehensive income
	The Company has no comprehensive income other than net income disclosed in the condensed consolidated statements of income.
	Segment information
	Under U.S. GAAP, operating segments are based on the internal information that management uses for allocating resources and assessing performance of the Company. The Company reports two operating segments – Property and Casualty Reinsurance and Catastrophe Risk Management. The Company also has a corporate function that includes the Company’s investment income on capital, certain general and administrative expenses related to its corporate activities, interest expense and income tax expense.
	Prior year changes in the presentation of condensed consolidated statements of cash flows
	The Company had previously excluded income attributable to non-controlling interests from cash flows provided by operating activities and included these amounts in cash flows used in investing activities and provided by financing activities. The Company began including income from non-controlling interests in cash flows provided by operating activities for the year ended December 31, 2014. In addition, cash flows related to the non-controlling interest in investment affiliate were previously included in net cash used in investing activities and is now being included in net cash provided by financing activities. Lastly, the Company now includes interest expense on deposit liabilities and the change in fair value of embedded derivatives in deposit liability contracts as non-cash adjustments in operating activities. These changes did not impact the condensed consolidated balance sheet or condensed consolidated statements of income for the prior periods. The Company modified the presentation of its condensed consolidated statements of cash flows for the three months ended March 31, 2014 to conform with the current year presentation.
Recently issued accounting standards
Issued and effective as of March 31, 2015
In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASU 2014-08). ASU 2014-08 changes the requirements for reporting discontinued operations, such that a disposal of a component of the Company’s operations is required to be reported as discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on the Company’s operations and financial results. ASU 2014-08 is effective for all disposals that occur after January 1, 2015, with early adoption permitted. The Company does not expect this new pronouncement to have a material impact on the Company’s condensed consolidated financial statements.
Issued but not yet effective as of March 31, 2015
In February 2015, the FASB issued Accounting Standard Update 2015-02, Consolidation (Topic 810) Amendments to the Consolidation Analysis (ASU 2015-02). ASU 2015-02 requires management to evaluate whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities. ASU 2015-02 eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 also provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in ASU 2015-02 are effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on the Company’s condensed consolidated financial statements.
In April 2015, the FASB issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (ASU 2015-03). ASU 2015-03 simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. The amendments in ASU 2015-03 are effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2015-03 effective with its debt issuance in February 2015.

	The Company’s Investment Manager has a formal valuation policy that sets forth the pricing methodology for investments to be used in determining the fair value of each security in the Company’s portfolio. The valuation policy is updated and approved at least on an annual basis by Third Point LLC’s valuation committee (the “Committee”), which is comprised of officers and employees who are senior business management personnel of Third Point LLC. The Committee meets monthly. The Committee’s role is to review and verify the propriety and consistency of the valuation methodology to determine the fair value of investments. The Committee also reviews any due diligence performed and approves any changes to current or potential external pricing vendors.
	Investments are carried at fair value. The fair values of investments are estimated using prices obtained from either third-party pricing services or broker quotes. The methodology for valuation is generally determined based on the investment’s asset class per the Company’s Investment Manager’s valuation policy. For investments where fair values from pricing services or brokers are unavailable, fair values are estimated using information obtained from the Company’s Investment Manager.
	Securities and commodities listed on a national securities or commodities exchange or quoted on NASDAQ are valued at their last sales price as of the last business day of the period. Listed securities with no reported sales on such date and over-the-counter (“OTC”) securities are valued at their last closing bid price if held long by the Company, and last closing ask price if held short by the Company. As of March 31, 2015, securities valued at $509.8 million (December 31, 2014 - $434.4 million), representing 24.8% (December 31, 2014 – 23.5%) of investments in securities and commodities and derivative assets, and $3.5 million (December 31, 2014 - $1.3 million), representing 2.9% (December 31, 2014 – 1.4%) of securities sold, not yet purchased and derivative liabilities, are valued based on broker quotes or other quoted market prices for similar securities.
	Private securities are not registered for public sale and are carried at an estimated fair value at the end of the period. Valuation techniques used by the Company may include market approach, last transaction analysis, liquidation analysis and/or using discounted cash flow models where the significant inputs could include but are not limited to additional rounds of equity financing, financial metrics such as revenue multiples or price-earnings ratio, discount rates and other factors. In addition, third party valuation firms may be employed to conduct separate valuations of such private securities. The third party valuation firms provide written reports documenting their recommended valuation as of the determination date for the specified investments.
	As of March 31, 2015, the Company had $10.3 million (December 31, 2014 - $2.3 million) of private securities fair valued by a third party valuation firm using information obtained from the Company’s Investment Manager. Private securities represented less than 1% of total investments in securities, commodities and derivative assets. The actual value at which these securities could actually be sold or settled with a willing buyer or seller may differ from the Company’s estimated fair values depending on a number of factors including, but not limited to, current and future economic conditions, the quantity sold or settled, the presence of an active market and the availability of a willing buyer or seller.
	The Company’s free standing derivatives are recorded at fair value, and are included in the condensed consolidated balance sheets in derivative assets and derivative liabilities. The Company values exchange-traded derivatives at their last sales price on the exchange where it is primarily traded. OTC derivatives, which include swap, option, swaption, forward, future and contract for differences, are valued by third party sources when available; otherwise, fair values are obtained from broker quotes that are based on pricing models that consider the time value of money, volatility, and the current market and contractual prices of the underlying financial instruments.
	As an extension of our underwriting activities, the Catastrophe Reinsurer has sold derivative instruments that provide reinsurance-like protection to third parties for specific loss events associated with certain lines of business.  These derivatives are recorded in the condensed consolidated balance sheets at fair value, with changes in the fair value of these derivatives recorded in net investment income in the condensed consolidated statements of income.  These contracts are valued on the basis of models developed by us, which approximates fair value.
	The Company also has derivatives embedded in non-derivative host contracts that are required to be separated from the host contracts and accounted for at fair value with changes in fair value of the embedded derivative reported in net investment income. The Company’s embedded derivatives relate to interest crediting features in certain reinsurance and deposit contracts that vary based on the returns on our investments managed by Third Point LLC. The Company determines the fair value of the embedded derivatives using models developed by the Company, which approximates fair value. See discussion of accounting policy for embedded derivatives in Note 2 for additional information.
	The Company’s holdings in asset-backed securities (“ABS”) are substantially invested in residential mortgage-backed securities (“RMBS”). The balance of the ABS positions was held in commercial mortgage-backed securities, collateralized debt obligations and student loan asset-backed securities. These investments are valued using broker quotes or a recognised third-party pricing vendor. All of these classes of ABS are sensitive to changes in interest rates and any resulting change in the rate at which borrowers sell their properties, refinance, or otherwise pre-pay their loans. As an investor in these classes of ABS, the Company may be exposed to the credit risk of underlying borrowers not being able to make timely payments on loans or the likelihood of borrowers defaulting on their loans. In addition, the Company may be exposed to significant market and liquidity risks.
	The Company values its investments in limited partnerships at fair value, which is estimated based on the Company’s share of the net asset value of the limited partnerships as provided by the investment managers of the underlying investment funds. The resulting net gains or net losses are reflected in the condensed consolidated statements of income.
	On December 18, 2014, we entered into a subscription agreement with the Kiskadee Diversified Fund Ltd. (“Kiskadee Fund”) to invest up to $25.0 million in Hiscox Insurance Company (Bermuda) Limited’s (“Hiscox”) separately managed insurance-linked securities platform, Kiskadee Re Ltd.  The Kiskadee Fund is a fund vehicle managed by Hiscox. The Kiskadee Fund invests in property catastrophe exposures through collateralized reinsurance transactions and other insurance-linked investments.  On January 2, 2015, we funded $5.0 million of this commitment.  The remaining $20.0 million commitment is due to be funded on June 1, 2015. This Company has elected the fair value option for this investment which is recorded on the condensed consolidated balance sheet at fair value as a Level 3 asset. The fair value is estimated based on the Company’s share of the net asset value in the Kiskadee Fund, as provided by the investment manager. The resulting net gains or losses are reflected in the condensed consolidated statements of income.
	The Company performs several processes to ascertain the reasonableness of the valuation of all of the Company’s investments comprising the Company’s investment portfolio, including securities that are categorized as Level 2 and Level 3 within the fair value hierarchy. These processes include i) obtaining and reviewing weekly and monthly investment portfolio reports from the Investment Manager, ii) obtaining and reviewing monthly Net Asset Value (“NAV”) and investment return reports received directly from the Company’s third-party fund administrator, which are compared to the reports noted in (i), and iii) monthly update discussions with the Company’s Investment Manager regarding the investment portfolio, including, their process for reviewing and validating pricing obtained from third party service providers.
	For the three months ended March 31, 2015 and 2014, there were no changes in the valuation techniques as it relates to the above.
	U.S. GAAP disclosure requirements establish a framework for measuring fair value, including a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. The three-level hierarchy of inputs is summarized below:
	•	Level 1 – Quoted prices available in active markets/exchanges for identical investments as of the reporting date.
	•	Level 2 – Observable inputs to the valuation methodology other than unadjusted quoted market prices for identical assets or liabilities in active markets. Level 2 inputs include, but are not limited to, prices quoted for similar assets or liabilities in active markets/exchanges, prices quoted for identical or similar assets or liabilities in markets that are not active and fair values determined through the use of models or other valuation methodologies.
	•	Level 3 – Pricing inputs unobservable for the investment and include activities where there is little, if any, market activity for the investment. The inputs applied in the determination of fair value require significant management judgment and estimation.
	Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources other than those of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.
	The key inputs for corporate, government and sovereign bond valuation are coupon frequency, coupon rate and underlying bond spread. The key inputs for asset-backed securities are yield, probability of default, loss severity and prepayment.
	Key inputs for over-the-counter (“OTC”) valuations vary based on the type of underlying security on which the contract was written:
	•	The key inputs for most OTC option contracts include notional, strike price, maturity, payout structure, current foreign exchange forward and spot rates, current market price of underlying and volatility of underlying.
	•	The key inputs for most forward contracts include notional, maturity, forward rate, spot rate, various interest rate curves and discount factor.
	•	The key inputs for swap valuation will vary based on the type of underlying on which the contract was written. Generally, the key inputs for most swap contracts include notional, swap period, fixed rate, credit or interest rate curves, current market or spot price of the underlying and the volatility of the underlying.
	The following tables present the Company’s investments, categorized by the level of the fair value hierarchy as of March 31, 2015 and December 31, 2014:

During the three months ended March 31, 2015, the Company made no significant reclassifications of assets or liabilities between Levels 1 and 2. During the year ended December 31, 2014, the Company reclassified $86.6 million of private common equity securities from Level 2 to Level 1 equity securities. This reclassification is the result of the issuer’s IPO, with quoted prices having become available in an active market as of the reporting date.

-1	Total change in realized and unrealized gain (loss) recorded on Level 3 financial instruments are included in net investment income in the condensed consolidated statements of income (loss).
Total unrealized losses related to fair value assets using significant unobservable inputs (Level 3) for the three months ended March 31, 2015 was $1.4 million (2014 - losses of $0.03 million).
For assets and liabilities that were transferred into Level 3 during the period, gains (losses) are presented as if the assets or liabilities had been transferred into Level 3 at the beginning of the period; similarly, for assets and liabilities that were transferred out of Level 3 during the year, gains (losses) are presented as if the assets or liabilities had been transferred out of Level 3 at the beginning of the year. The Company held no Level 3 investments where quantitative unobservable inputs are produced by the Company itself when estimating fair value.
The following table summarizes information about the significant unobservable inputs used in determining the fair value of the Level 3 investments held by the Company.  Level 3 investments not presented in the table below generally do not have any unobservable inputs to disclose, as they are valued primarily using dealer quotes, at cost or net asset value for investment in limited partnerships.

Due to and from Broker-Dealers and Clearing Organizations [Abstract]
Due from/to brokers	The Company holds substantially all of its investments through its prime brokers pursuant to agreements between the Company and each prime broker. The brokerage arrangements differ from broker to broker, but generally cash and investments in securities and commodities balances are available as collateral against investments in securities sold, not yet purchased and derivative positions, if required.
	Due from/to brokers include cash balances maintained with the Company’s prime brokers, investment receivables, margin debt balances, receivables and payables from unsettled trades and proceeds from securities sold, not yet purchased. In addition, due from and to brokers includes cash collateral received and posted from OTC and repurchase agreement counterparties. As of March 31, 2015, the Company’s due from/to brokers includes a total non-U.S. currency balance of $17.8 million (December 31, 2014 - payable of $1.1 million).
	The Company uses prime brokerage arrangements to provide cash collateral for its letter of credit facilities and to fund trust accounts securing certain reinsurance contracts.  As of March 31, 2015, the Company had $508.0 million (December 31, 2014 - $308.8 million) of restricted cash securing letter of credit facilities and certain reinsurance contracts. Margin debt at the brokers primarily relates to borrowings to fund collateral arrangements and investment activity. Amounts are borrowed through committed facilities with terms of up to 90 days, secured by assets of the Company held by the prime broker, and incur interest based on the Company’s negotiated rates.  This interest expense is reflected in net investment income in the condensed consolidated statements of income.

*Unrealized gain (loss) relates to derivatives still held at reporting date.
The Company’s derivative contracts are generally subject to the International Swaps and Derivatives Association (“ISDA”) Master Agreements or other similar agreements which contain provisions setting forth events of default and/or termination events (“credit-risk-related contingent features”), including but not limited to provisions setting forth maximum permissible declines in the Company’s net asset value. Upon the occurrence of a termination event with respect to an ISDA Agreement, the Company’s counterparty could elect to terminate the derivative contracts governed by such agreement, resulting in the realization of any net gains or losses with respect to such derivative contracts and the return of collateral held by such party. During the three months ended March 31, 2015, no termination events were triggered under the ISDA Master Agreements. As of March 31, 2015, the aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position was $7.9 million (December 31, 2014 - $1.9 million) for which the Company posted $87.0 million (December 31, 2014 - $27.6 million) of collateral in the normal course of business. Similarly, the Company held collateral (approximately $2.4 million) in cash from certain counterparties as of March 31, 2015. If the credit-risk-related contingent features underlying these instruments had been triggered as of March 31, 2015 and the Company had to settle these instruments immediately, no additional amounts would be required to be posted that would exceed the settlement amounts of open derivative contracts or in the case of cross margining relationships, the assets in the Company’s prime brokerage accounts are sufficient to offset the derivative liabilities.
The Company’s derivatives do not qualify as hedges for financial reporting purposes and are recorded in the condensed consolidated financial statements on a gross basis and not offset against any collateral pledged or received. Pursuant to ISDA master agreements and other counterparty agreements, the Company and its counterparties typically have the ability to net certain payments owed to each other in specified circumstances. In addition, in the event a party to one of the ISDA master agreements or other derivatives agreements defaults, or a transaction is otherwise subject to termination, the non-defaulting party generally has the right to set off against payments owed to the defaulting party or collateral held by the non-defaulting party.
The Company does not offset its derivative instruments and presents all amounts in the condensed consolidated balance sheets on a gross basis. The Company has pledged cash collateral to counterparties to support the current value of amounts due to the counterparties based on the value of the underlying security. As of March 31, 2015 and December 31, 2014, the gross and net amounts of derivative instruments and repurchase and reverse repurchase agreements that are subject to enforceable master netting arrangements or similar agreements were as follows:

Loss and Loss Adjustment Expense Reserves [Abstract]
Loss and loss adjustment expense reserves	As of March 31, 2015 and December 31, 2014, loss and loss adjustment expense reserves in the condensed consolidated balance sheets was comprised of the following:
		March 31,			December 31,
		2015			2014
		($ in thousands)
	Case loss and loss adjustment expense reserves	$	57,211		$	64,343

	Net reserve for loss and loss adjustment expenses, end of year	273,529			154,347
	Plus: loss and loss adjustment expenses recoverable, end of year	408			10,277
	Gross reserve for loss and loss adjustment expenses, end of year	$	273,937		$	164,624
	The $2.2 million decrease in prior years’ reserves for the three months ended March 31, 2015 reflects $6.1 million of favorable reserve development partially offset by $3.9 million resulting from increases in premium estimates on certain contracts. The prior years’ reserve development is explained as follows:
	•	The $6.1 million of favorable reserve development is offset by increases of $7.1 million in acquisition costs primarily as a result of changes in the estimated split of the composite ratio between loss and loss adjustment expenses incurred and acquisition costs for certain contracts that have sliding scale commissions and profit commissions that vary inversely with loss experience. The net impact as a result of changes in prior years’ reserves was a decrease in net underwriting income of $1.0 million for the three months ended March 31, 2015.
	•	The $3.9 million increase in loss and loss adjustment expenses incurred related to the increase in premium estimates on certain contracts was accompanied by a $2.6 million increase in acquisition costs, for a total of $6.5 million increase in loss and loss adjustment expenses incurred and acquisition costs. The related increase in earned premium related to the increase in premium estimates was $6.5 million, resulting in an insignificant change in net underwriting loss for the three months ended March 31, 2015.
	•	In total, the change in underwriting income for prior periods due to loss reserve development and adjustments to premium estimates was a decrease of $1.0 million for the three months ended March 31, 2015.
	The net paid losses of $84.2 million for the three months ended March 31, 2015 included $63.5 million of paid losses related to two contracts that were commuted in the quarter compared to $nil for the three months ended March 31, 2014.
	The $3.0 million increase in prior years’ reserves for the three months ended March 31, 2014 reflects $2.0 million of adverse loss development, primarily related to one crop contract, and $1.0 million related to premium estimate increases on certain other contracts. The change in loss and loss adjustment expense reserves related to premium estimate changes and were accompanied by similar changes in the premium earned for those contracts, resulting in minimal impact to net underwriting income for that period.

Management, Performance and Founders Fees [Abstract]
Management, performance and founders fees	The Company, Third Point Re and Third Point Re USA are party to Joint Venture and Investment Management Agreements (the “Investment Agreements”) with Third Point LLC and Third Point Advisors LLC under which Third Point LLC manages certain jointly held assets.
	Pursuant to the Investment Agreements, Third Point Advisors LLC receives an annual performance fee allocation equal to 20% of the net investment income of the Company’s share of the investment assets managed by Third Point LLC, subject to a loss carry forward provision. Additionally, a total management fee equal to 2% annually of the Company’s share of the investment assets managed by Third Point LLC is paid to Third Point LLC and various Founders of the Company. Management fees are paid monthly, whereas performance fees are paid annually, in arrears.
	Investment fee expenses related to the Investment Agreements, which are included in net investment income in the condensed consolidated statements of income for the three months ended March 31, 2015 and 2014 are as follows:
		2015		2014

Deposit Contracts, Liabilities [Abstract]
Deposit contracts	Deposit liability contracts each contain a fixed interest crediting rate. Certain deposit contracts also contain a variable interest crediting feature based on actual investment returns realized by the Company that can increase the overall effective interest crediting rate on those contracts. These variable interest crediting features are considered embedded derivatives. We include the estimated fair value of these embedded derivatives with the host deposit liability contracts. Changes in the estimated fair value of these embedded derivatives are recorded in other expenses in the condensed consolidated statements of income.
	The following table represents activity in the deposit liabilities for the three months ended March 31, 2015 and year ended December 31, 2014:

Income Tax Disclosure [Abstract]
Income taxes	We provide for income tax expense or benefit based upon pre-tax income reported in the condensed consolidated financial statements and the provisions of currently enacted tax laws.  The Company and its Bermuda subsidiaries are incorporated under the laws of Bermuda and are subject to Bermuda law with respect to taxation.  Under current Bermuda law, the Company and its Bermuda subsidiaries are not subject to any income or capital gains taxes. In the event that such taxes are imposed, the Company and its Bermuda subsidiaries would be exempted from any such taxes until March 2035 under the Tax Assurance Certificates issued to such entities pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966, as amended.
	The Company has an operating subsidiary incorporated in Bermuda, Third Point Re USA, which made an election to pay taxes in the United States of America under Section 953(d) of the U.S. Internal Revenue Code of 1986, as amended. The operations of Third Point Re USA will be subject to U.S. federal income taxes generally at a rate of 35%. Any of our non-U.S. subsidiaries could become subject to U.S. federal income tax only to the extent that they derive income from activity that is deemed to be the conduct of a trade or business within the United States.  We do not consider our non-U.S. subsidiaries to be engaged in a trade or business within the United States and, therefore, do not believe that our non-U.S. subsidiaries are subject to U.S. federal income tax.  However, there is little legal precedent as to what constitutes being engaged in a trade or business within the United States and, thus, there exists the possibility that the U.S. Internal Revenue Service could assert claims that our non-U.S. subsidiaries are engaged in a trade or business in the United States and attempt to assess taxes that are not provided for.
	The Company also has subsidiaries in the United Kingdom, TPRUK and TPRUK Holdings, which are subject to applicable taxes in that jurisdiction.  On July 17, 2013, the U.K. government passed the Finance Act 2013, which reduced the corporate income tax rate from 23% to 21% (effective April 1, 2014) and provided for a further reduction in the corporate income tax rate from 21% to 20% (effective April 1, 2015).
	The Company is subject to withholding taxes on income sourced in the United States and in other countries, subject to the countries’ specific tax regulations where the income originated. Income subject to withholding taxes include, but is not limited to, dividends, capital gains and interest on certain investments.
	The Company is also subject to uncertain tax positions related to investment transactions in certain foreign jurisdictions. As of March 31, 2015, the Company has accrued $2.6 million for uncertain tax positions.
	For the three months ended March 31, 2015 and 2014, the Company recorded income tax expenses, as follows:

	The fair value of share options issued were estimated on the grant date using the Black-Scholes option-pricing model. There were no options granted in the three months ended March 31, 2015. The share price used for purposes of determining the fair value of share options that were granted in the year ended December 31, 2014 was $15.05.

The other assumptions used in the option-pricing model were as follows: risk free interest rate of 2.2%, expected life of 6.5 years and a 0.0% dividend yield. As of March 31, 2015, the weighted average remaining contractual term for options outstanding was 6.9 years (December 31, 2014 - 7.1 years).
	The following table summarizes information about the Company’s management and director share options outstanding as of March 31, 2015:

	(b)	Restricted shares with service condition
	Restricted shares vest either ratably or at the end of the required service period and contain certain restrictions during the vesting period, relating to, among other things, forfeiture in the event of termination of employment or service and transferability.
	Restricted share award activity for the restricted shares with only a service condition for the three months ended March 31, 2015 and year ended December 31, 2014 was as follows:

Performance based restricted shares vest based on continued service and the achievement of certain financial performance measures over a three-year performance measurement period. The number of performance-based restricted shares that may be retained upon vesting will vary based on the level of achievement of the performance goals. The vesting date for these awards are March 1, 2017 and March 1, 2018, respectively.

Guarantees [Abstract]
Financial instruments with off-balance sheet risk or concentrations of credit risk	Off-balance sheet risk
	In the normal course of business, the Company trades various financial instruments and engages in various investment activities with off-balance sheet risk. These financial instruments include securities sold, not yet purchased, forwards, futures, options, swaptions, swaps and contracts for differences. Generally, these financial instruments represent future commitments to purchase or sell other financial instruments at specific terms at specified future dates. Each of these financial instruments contains varying degrees of off-balance sheet risk whereby changes in the fair values of the securities underlying the financial instruments or fluctuations in interest rates and index values may exceed the amounts recognized in the condensed consolidated balance sheets.
	Securities sold, not yet purchased are recorded as liabilities in the condensed consolidated balance sheets and have market risk to the extent that the Company, in satisfying its obligations, may be required to purchase securities at a higher value than that recorded in the condensed consolidated balance sheets. The Company’s investments in securities and commodities and amounts due from brokers are partially restricted until the Company satisfies the obligation to deliver securities sold, not yet purchased.
	Forward and futures contracts are a commitment to purchase or sell financial instruments, currencies or commodities at a future date at a negotiated rate. Forward and futures contracts expose the Company to market risks to the extent that adverse changes occur to the underlying financial instruments such as currency rates or equity index fluctuations.
	Option contracts give the purchaser the right, but not the obligation, to purchase from or sell to the option writer financial instruments, commodities or currencies within a defined time period for a specified price. The premium received by the Company upon writing an option contract is recorded as a liability, marked to market on a daily basis and is included in securities sold, not yet purchased in the condensed consolidated balance sheets. In writing an option, the Company bears the market risk of an unfavorable change in the financial instrument underlying the written option. Exercise of an option written by the Company could result in the Company selling or buying a financial instrument at a price different from the current fair value.
	In the normal course of trading activities in its investment portfolio, the Company trades and holds certain derivative contracts, such as written options, which constitute guarantees. The maximum payout for written put options is limited to the number of contracts written and the related strike prices and the maximum payout for written call options is dependent upon the market price of the underlying security at the date of a payout event. As of March 31, 2015, the investment portfolio had a maximum payout amount of approximately $963.8 million (December 31, 2014 - $666.9 million) relating to written put option contracts with expiration ranging from one month to 10 months from the balance sheet date. The maximum payout amount could be offset by the subsequent sale, if any, of assets obtained via the settlement of a payout event. The fair value of these written put options as of March 31, 2015 was $19.8 million (December 31, 2014 - $4.5 million) and is included in securities sold, not yet purchased in the condensed consolidated balance sheets.
	Swaption contracts give the Company the right, but not the obligation, to enter into a specified interest-rate swap within a specified period of time. The Company’s market and counterparty credit risk is limited to the premium paid to enter into the swaption contract and net unrealized gains.
	Total return swaps, contracts for differences, index swaps, and interest rate swaps that involve the exchange of cash flows between the Company and counterparties are based on the change in the fair value of a particular equity, index, or interest rate on a specified notional holding. The use of these contracts exposes the Company to market risks equivalent to actually holding securities of the notional value but typically involve little capital commitment relative to the exposure achieved. The gains or losses of the Company may therefore be magnified on the capital commitment.
	Credit derivatives
	Credit default swaps protect the buyer against the loss of principal on one or more underlying bonds, loans, or mortgages in the event the issuer suffers a credit event. Typical credit events include failure to pay or restructuring of obligations, bankruptcy, dissolution or insolvency of the underlying issuer. The buyer of the protection pays an initial and/or a periodic premium to the seller and receives protection for the period of the contract. If there is not a credit event, as defined in the contract, the buyer receives no payments from the seller. If there is a credit event, the buyer receives a payment from the seller of protection as calculated by the contract between the two parties.
	The Company may also enter into index and/or basket credit default swaps where the credit derivative may reference a basket of single-name credit default swaps or a broad-based index. Generally, in the event of a default on one of the underlying names, the buyer will receive a pro-rata portion of the total notional amount of the credit default index or basket contract from the seller. When the Company purchases single-name, index and basket credit default swaps, the Company is exposed to counterparty nonperformance.
	Upon selling credit default swap protection, the Company may expose itself to the risk of loss from related credit events specified in the contract. Credit spreads of the underlying together with the period of expiration is indicative of the likelihood of a credit event under the credit default swap contract and the Company’s risk of loss. Higher credit spreads and shorter expiration dates are indicative of a higher likelihood of a credit event resulting in the Company’s payment to the buyer of protection. Lower credit spreads and longer expiration dates would indicate the opposite and lowers the likelihood the Company needs to pay the buyer of protection. As of March 31, 2015, there was no cash collateral received specifically related to written credit default swaps as collateral is based on the net exposure associated with all derivative instruments subject to applicable netting agreements with counterparties and may not be specific to any individual derivative contract.
	The following table sets forth certain information related to the Company’s written credit derivatives as of March 31, 2015 and December 31, 2014:

	-1	As of March 31, 2015 and December 31, 2014, the Company did not hold any offsetting buy protection credit derivatives with the same underlying reference obligation.
	-2	Fair value amounts of derivative contracts are shown on a gross basis prior to cash collateral or counterparty netting.
	Concentrations of credit risk
	In addition to off-balance sheet risks related to specific financial instruments, the Company may be subject to concentrations of credit risk with particular counterparties. Substantially all securities transactions of the Company are cleared by several major securities firms. The Company had substantially all such individual counterparty concentration with these brokers or their affiliates as of March 31, 2015. However, the Company reduces its credit risk with counterparties by entering into master netting agreements. Therefore, assets represent the Company’s greater unrealized gains less unrealized losses for derivative contracts in which the Company has master netting agreements. Similarly, liabilities represent the Company’s greater unrealized losses less unrealized gains for derivative contracts in which the Joint Venture has master netting agreements. Furthermore, the Company obtains collateral from counterparties to reduce its exposure to counterparty credit risk.
	The Company’s maximum exposure to credit risk associated with counterparty nonperformance on derivative contracts is limited to the net unrealized gains by counterparties inherent in such contracts which are recognised in the condensed consolidated balance sheets. As of March 31, 2015, the Company’s maximum counterparty credit risk exposure was $5.7 million (December 31, 2014 - $9.7 million).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Investments
	Loan and other participation interests purchased by the Company, such as bank debt, may include revolving credit arrangements or other financing commitments obligating the Company to advance additional amounts on demand. As of March 31, 2015, the Company had one unfunded capital commitment of $4.2 million related to its investment in the Hellenic Fund (see Note 17 for additional information).
	In the normal course of business, the Company, as part of its investment strategy, enters into contracts that contain a variety of indemnifications and warranties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. Thus, no amounts have been accrued related to such indemnifications. The Company also indemnifies Third Point Advisors LLC, Third Point LLC and its employees from and against any loss or expense, including, without limitation any judgment, settlement, legal fees and other costs. Any expenses related to this indemnification are reflected in net investment income in the condensed consolidated statements of income.
	See Note 4 for information regarding investment commitment to Kiskadee Fund.
	Financing
	On February 13, 2015, TPRUSA issued $115.0 million of Notes due February 13, 2025. The Notes bear interest at 7.0% and interest is payable semi-annually on February 13 and August 13 of each year, beginning August 13, 2015. The Notes are fully and unconditionally guaranteed by Third Point Reinsurance Ltd., and, in certain circumstances specified in the indenture governing the Notes, certain existing or future subsidiaries of the Company may be required to guarantee the Notes.
	Litigation
	From time to time in the normal course of business, the Company may be involved in formal and informal dispute resolution procedures, which may include arbitration or litigation, the outcomes of which determine the rights and obligations under the Company’s reinsurance contracts and other contractual agreements. In some disputes, the Company may seek to enforce its rights under an agreement or to collect funds owing to it.  In other matters, the Company may resist attempts by others to collect funds or enforce alleged rights. While the final outcome of legal disputes that may arise cannot be predicted with certainty, the Company is not currently involved in any material formal or informal dispute resolution procedures.

Significant accounting policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Use of estimates	Use of estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The major estimates reflected in the Company’s condensed consolidated financial statements include, but are not limited to, the loss and loss adjustment expense reserves, estimates of written and earned premiums and fair value of financial instruments.
Cash and restricted cash and cash equivalents	Cash and restricted cash and cash equivalents
	Cash and cash equivalents consist of cash held in banks and other short-term, highly liquid investments with original maturity dates of ninety days or less.
	Restricted cash and cash equivalents consist of cash held in trust accounts with the Catastrophe Reinsurer, securing collateralized reinsurance contracts written, trust accounts securing obligations under certain reinsurance contracts and cash held with banks securing letters of credit issued under credit facilities.
Premium revenue recognition	Premium revenue recognition
	To the extent that the amount of written premium is estimable, the Company estimates the ultimate premiums for the entire contract period and records this estimate at the inception of the contract. For contracts where the full written premium is not estimable at inception, the Company records written premium for the portion of the contract period for which the amount is estimable. These estimates are based primarily on information in the underlying contracts as well as information provided by clients and/or brokers.
	Changes in premium estimates are expected and may result in adjustments in any reporting period. These estimates change over time as additional information regarding the underlying business volume is obtained. Any subsequent adjustments arising on such estimates are recorded in the period in which they are determined.
	Premiums written are earned over the exposure period in proportion to the period of risk covered. Unearned premiums represent the portion of premiums written that relate to the remaining term of the underlying policies in force.
	Premiums for retroactive exposures in reinsurance contracts are earned at the inception of the contract, as all of the underlying loss events covered by these exposures occurred in the past. Any underwriting profit at inception related to retroactive exposures in a reinsurance contract is deferred and recognised over the estimated future payout of the loss and loss adjustment expense reserves. Any underwriting loss at inception related to retroactive exposures in a reinsurance contract is recognised immediately.
Reinsurance premiums ceded	Reinsurance premiums ceded
	From time to time the Company reduces the risk of losses on business written by reinsuring certain risks and exposures with other reinsurers. The Company remains liable to the extent that any retrocessionaire fails to meet its obligations and to the extent that the Company does not hold sufficient security for their unpaid obligations. Ceded premiums are written during the period in which the risks incept and are expensed over the contract period in proportion to the period of risk covered. Unearned premiums ceded consist of the unexpired portion of reinsurance ceded.
Deferred acquisition costs	Deferred acquisition costs
	Acquisition costs consist of commissions, brokerage and excise taxes that are related directly to the successful acquisition of new or renewal reinsurance contracts. These costs are deferred and amortized over the period in which the related premiums are earned. The Company evaluates the recoverability of deferred acquisition costs by determining if the sum of future earned premiums and anticipated investment income is greater than expected future loss and loss adjustment expenses and acquisition costs. If a loss is probable on the unexpired portion of contracts in force, a premium deficiency loss is recognized. As of March 31, 2015, deferred acquisition costs are considered to be fully recoverable and no premium deficiency has been recorded.
	Acquisition costs also include profit commissions that are expensed when incurred. Profit commissions are calculated and accrued based on the expected loss experience for contracts and recorded when the current loss estimate indicates that a profit commission is probable under the contract terms.
Loss and loss adjustment expense reserves	Loss and loss adjustment expense reserves
	The Company’s loss and loss adjustment expense reserves include case reserves, reserves for losses incurred but not yet reported (“IBNR reserves”) and deferred profit reserves for retroactive exposures in reinsurance contracts. Case reserves are established for losses that have been reported, but not yet paid. IBNR reserves represent the estimated loss and loss adjustment expenses that have been incurred by insureds and reinsureds but not yet reported to the insurer or reinsurer, including unknown future development on loss and loss adjustment expenses that are known to the insurer or reinsurer. IBNR reserves are established by management based on actuarially determined estimates of ultimate loss and loss adjustment expenses.
	Inherent in the estimate of ultimate loss and loss adjustment expenses are expected trends in claim severity and frequency and other factors that may vary significantly as claims are settled. Accordingly, ultimate loss and loss adjustment expenses may differ materially from the amounts recorded in the condensed consolidated financial statements. These estimates are reviewed regularly and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Such adjustments, if any, are recorded in the condensed consolidated statements of income in the period in which they become known.
Deposit liabilities	Deposit liabilities
	Certain contracts do not transfer sufficient insurance risk to be deemed reinsurance contracts and are accounted for using the deposit method of accounting. Management exercises judgment in determining whether contracts transfer sufficient risk to be accounted for as reinsurance contracts. Using the deposit method of accounting, a deposit liability, rather than written premium, is initially recorded based upon the consideration received less any explicitly identified premiums or fees. In subsequent periods, the deposit liability is adjusted by calculating the effective yield on the deposit to reflect actual payments to date and future expected payments.
Fair value measurement	Fair value measurement
	The Company determines the fair value of financial instruments in accordance with current accounting guidance, which defines fair value and establishes a three level fair value hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. Fair value is defined as the price that the Company would receive to sell an asset or would pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Company determines the estimated fair value of each individual security utilizing the highest level inputs available.
	The fair value of the Company’s assets and liabilities, which qualify as financial instruments, approximates the carrying amounts presented in the condensed consolidated balance sheets.
Investments	Investments
	The Company’s investments are classified as “trading securities” and are carried at fair value with changes in fair value included in earnings in the condensed consolidated statements of income.
	The fair value of the Company’s investments are based on quoted market prices, or when such prices are not available, by reference to broker or underwriter bid indications, industry recognized pricing vendors, and/or internal pricing valuation techniques. Investment transactions are recorded on a trade date basis with balances pending settlement included in due to/from brokers in the condensed consolidated balance sheets.
	Realized gains and losses are determined using cost calculated on a specific identification basis. Dividends are recorded on the ex-dividend date. Income and expense are recorded on the accrual basis including interest and premiums amortized and discounts accreted.
Derivatives	Derivatives
	Underwriting
	The Catastrophe Reinsurer enters into certain contracts under which the potential loss payments are triggered exclusively by reference to a specified index, such as an industry loss. These contracts are considered derivatives. The Company records the fair value of these contracts in derivative liabilities, at fair value, in the condensed consolidated balance sheet. Changes in the fair value of these contracts are recorded in net investment income in the condensed consolidated statement of income.
	Investments
	Derivative instruments within our investment assets managed by our investment manager Third Point LLC, are recorded in the condensed consolidated balance sheets at fair value, with changes in fair values and realized gains and losses recognised in net investment income in the condensed consolidated statements of income.
	Derivatives serve as a key component of the Company’s investment strategy and are utilized primarily to structure the portfolio, or individual investments, and to economically match the investment objectives of the Company. The Company’s derivatives do not qualify as hedges for financial reporting purposes and are recorded in the condensed consolidated balance sheets on a gross basis and not offset against any collateral pledged or received. Pursuant to the International Swaps and Derivatives Association (“ISDA”) master agreements, securities lending agreements and other derivatives agreements, the Company and its counterparties typically have the ability to net certain payments owed to each other in specified circumstances. In addition, in the event a party to one of the ISDA master agreements, securities lending agreements or other derivatives agreements defaults, or a transaction is otherwise subject to termination, the non-defaulting party generally has the right to set off against payments owed to the defaulting party or collateral held by the non defaulting party.
	The Company enters into derivative contracts to manage credit risk, interest rate risk, currency exchange risk, and other exposure risks. The Company uses derivatives in connection with its risk-management activities to economically hedge certain risks and to gain exposure to certain investments. The utilization of derivative contracts also allows for an efficient means by which to trade certain asset classes.
	Fair values of derivatives are determined by using quoted market prices, industry recognized pricing vendors, and counterparty quotes when available; otherwise fair values are based on pricing models that consider the time value of money, volatility, and the current market and contractual prices of underlying financial instruments.
	Embedded derivatives
	Certain of the Company’s deposit and reinsurance contracts contain interest crediting features that vary based on the net investment return on investments managed by Third Point LLC. These contractual features are considered embedded derivatives in accordance with U.S. GAAP. We include the estimated fair value of these embedded derivatives in the condensed consolidated balance sheets with the host contract in order to reflect the expected settlement of these features with the host contract.
Share-based compensation	Share-based compensation
	The Company accounts for its share-based compensation transactions using the fair value of the award at the grant date. Determining the fair value of share purchase options at the grant date requires estimation and judgment. The Company uses an option-pricing model (Black-Scholes) to calculate the fair value of share purchase options.
	For share purchase options or restricted share awards granted that contain both a service and performance condition, the Company recognizes share compensation expense only for the portion of the options or restricted share awards that are considered probable of vesting. Share compensation for share purchase options or restricted share awards considered probable of vesting is expensed over the service (vesting) period on a graded vesting basis. The probability of share purchase options or restricted share awards vesting is evaluated at each reporting period.  When the share purchase options or restricted share awards are considered probable of vesting, the Company records a true up of share compensation expense from the grant date (service inception date) to the current reporting period end based on the fair value of the options or restricted share awards at the grant date.
	The Company measures grant date fair value for restricted share awards, with a service condition only, based on the price of its common shares at the grant date and the expense is recognised on a straight-line basis over the vesting period.
Warrants	Warrants
	The Company accounts for warrant contracts issued to certain of its founding investors (“Founders”) in conjunction with the initial capitalization of the Company by using either the physical settlement or net-share settlement methods. The fair value of these warrants was recorded in equity as additional paid-in capital. The fair value of warrants issued are estimated on the grant date using the Black-Scholes option-pricing model.
	The Company accounts for certain warrant contracts issued to an advisor, where services have been received by the Company, in part, in exchange for equity instruments, based on the fair value of such services. The associated cost of these warrants has been recorded as capital raise costs and is included in additional paid in capital in the condensed consolidated statements of shareholders’ equity.
Offering costs	Debt offering costs
	Costs incurred in issuing debt, which includes underwriters’ fees, legal and accounting fees, printing and other fees are capitalized and presented as a direct deduction from the senior notes payable in the condensed consolidated balance sheets. These costs are amortized over the term of the debt and are included in interest expense in the condensed consolidated statements of income.
Foreign currency transactions	Foreign currency transactions
	The Company’s functional currency is the U.S. dollar. Transactions involving monetary assets and liabilities denominated in foreign currencies have been converted into U.S. dollars at the exchange rate in effect on the balance sheet date, and the related revenues and expenses are converted using specific rates for the period, as appropriate. Net foreign currency transaction gains and losses arising from these activities are reported in the condensed consolidated statements of income in the period in which they arise.
	The Company does not isolate the portion of the net investment income resulting from changes in foreign exchange rates on investments, dividends and interest from the fluctuations arising from changes in fair values of securities and derivatives held. Periodic payments received or paid on swap agreements are recorded as realized gain or loss on investment transactions. Such fluctuations are included within net investment income in the condensed consolidated statements of income.
Income taxes and uncertain tax positions	Income taxes
	We provide for income taxes for our operations in income tax paying jurisdictions. Our provision relies on estimates and interpretations of currently enacted tax laws. We recognize deferred tax assets and liabilities based on the temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Such temporary differences are primarily due to tax basis discounts on loss and loss adjustment expense reserves and unearned premiums, deferred acquisition costs and investments. A valuation allowance against deferred tax assets is recorded if it is more likely than not that all, or some portion, of the benefits related to deferred tax assets will not be realized. Any adjustments to deferred income taxes are accounted for as changes in estimates and are reflected in the condensed consolidated statements of income in the period in which they are made. Any adjustments could be material and could significantly impact earnings in the period they are recorded.
Non-controlling interests	Non-controlling interests
	The Company consolidates the results of entities in which it has a controlling financial interest. The Company records the portion of shareholders’ equity attributable to non-controlling interests as a separate line within shareholders’ equity in the condensed consolidated balance sheets. The Company records the portion of income attributable to non-controlling interests as a separate line within the condensed consolidated statements of income.
Earnings per share	Earnings per share
	Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the period. The weighted average number of common shares excludes any dilutive effect of outstanding warrants, options and convertible securities such as unvested restricted shares. Diluted earnings per share is based on the weighted average number of common shares and share equivalents including any dilutive effects of warrants, options and other awards under share plans and are determined using the treasury stock method. U.S. GAAP requires that unvested share awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid (referred to as “participating securities”), be included in the number of shares outstanding for both basic and diluted earnings per share calculations. The Company treats certain of its unvested restricted shares as participating securities. In the event of a net loss, the participating securities are excluded from the calculation of both basic and diluted loss per share.
Leases	Leases
	Leases in which substantially all of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are recognised in the condensed consolidated statements of income on a straight-line basis over the term of the lease.
Comprehensive income	Comprehensive income
	The Company has no comprehensive income other than net income disclosed in the condensed consolidated statements of income.
Segment information	Segment information
	Under U.S. GAAP, operating segments are based on the internal information that management uses for allocating resources and assessing performance of the Company. The Company reports two operating segments – Property and Casualty Reinsurance and Catastrophe Risk Management. The Company also has a corporate function that includes the Company’s investment income on capital, certain general and administrative expenses related to its corporate activities, interest expense and income tax expense.
Prior year changes in the presentation of consolidated statements of cash flows	Prior year changes in the presentation of condensed consolidated statements of cash flows
	The Company had previously excluded income attributable to non-controlling interests from cash flows provided by operating activities and included these amounts in cash flows used in investing activities and provided by financing activities. The Company began including income from non-controlling interests in cash flows provided by operating activities for the year ended December 31, 2014. In addition, cash flows related to the non-controlling interest in investment affiliate were previously included in net cash used in investing activities and is now being included in net cash provided by financing activities. Lastly, the Company now includes interest expense on deposit liabilities and the change in fair value of embedded derivatives in deposit liability contracts as non-cash adjustments in operating activities. These changes did not impact the condensed consolidated balance sheet or condensed consolidated statements of income for the prior periods. The Company modified the presentation of its condensed consolidated statements of cash flows for the three months ended March 31, 2014 to conform with the current year presentation.
Recently issued accounting standards	Recently issued accounting standards
	Issued and effective as of March 31, 2015
	In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASU 2014-08). ASU 2014-08 changes the requirements for reporting discontinued operations, such that a disposal of a component of the Company’s operations is required to be reported as discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on the Company’s operations and financial results. ASU 2014-08 is effective for all disposals that occur after January 1, 2015, with early adoption permitted. The Company does not expect this new pronouncement to have a material impact on the Company’s condensed consolidated financial statements.
	Issued but not yet effective as of March 31, 2015
	In February 2015, the FASB issued Accounting Standard Update 2015-02, Consolidation (Topic 810) Amendments to the Consolidation Analysis (ASU 2015-02). ASU 2015-02 requires management to evaluate whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities. ASU 2015-02 eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 also provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in ASU 2015-02 are effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on the Company’s condensed consolidated financial statements.
	In April 2015, the FASB issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (ASU 2015-03). ASU 2015-03 simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. The amendments in ASU 2015-03 are effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2015-03 effective with its debt issuance in February 2015.
