	Third Point Reinsurance Ltd. (the “Company”) was incorporated as an exempted company under the laws of Bermuda on October 6, 2011 and, through its wholly-owned subsidiary Third Point Reinsurance Company Ltd. (“Third Point Re”), is a provider of global specialty property and casualty reinsurance products. Third Point Re was incorporated in Bermuda and is registered as a Class 4 insurer under the Insurance Act 1978, as amended, and related regulations (the “Act”). Third Point Re commenced reinsurance operations in January 2012.
	On June 15, 2012, Third Point Reinsurance Opportunities Fund Ltd. (the “Catastrophe Fund”), Third Point Reinsurance Investment Management Ltd. (the “Catastrophe Fund Manager”), and Third Point Re Cat Ltd. (the “Catastrophe Reinsurer”) were incorporated in Bermuda. The Company subsequently announced a strategic arrangement with Hiscox Insurance Company (Bermuda) Limited (“Hiscox”) to launch a collateralized catastrophe reinsurance underwriting fund management business. The Catastrophe Fund Manager, a Bermuda exempted company, is the investment manager of the Catastrophe Fund and is 85% owned by Third Point Re and 15% owned by Hiscox. The Catastrophe Fund Manager is responsible for the investment and management of the Catastrophe Fund’s assets. The Catastrophe Fund is an exempted company incorporated in Bermuda and is open to both related party and third party investors. The Catastrophe Fund Manager also acts as manager of the Catastrophe Reinsurer and, in this capacity, is responsible for overseeing the underwriting and investment activities of the Catastrophe Reinsurer. The Catastrophe Reinsurer is a Bermuda exempted company and is licensed as a special purpose insurer under the Act.
	On August 2, 2012, the Company established a wholly-owned subsidiary in the United Kingdom, Third Point Re Marketing (UK) Limited. (“TPRUK”). On May 20, 2013, TPRUK was licensed as an insurance intermediary by the UK Financial Conduct Authority.
	On August 20, 2013, the Company completed an initial public offering (“IPO”) of 24,832,484 common shares at an offering price of $12.50 per share. The net proceeds of the offering were $286.0 million, after deducting offering costs. The Company's common shares are listed on the New York Stock Exchange under the symbol “TPRE”.
	These consolidated financial statements include the results of the Company and its wholly and majority owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). All significant intercompany accounts and transactions have been eliminated.

Accounting Policies [Abstract]	'
Significant accounting policies	'
	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 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 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 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 and cash held with brokers securing letters of credit issued under credit facilities.
	Premium revenue recognition
	The Company estimates the ultimate premiums for the entire contract period and records this estimate at the inception of the contract, to the extent that the amount of written premium is estimable. 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.
	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 reinsurance contracts, where the Company has evaluated and concluded that risk transfer has occured, are earned at the inception of the contract, as all of the underlying loss events covered by these contracts occurred in the past. Any underwriting profit at inception of a retroactive reinsurance contract is deferred and recognised over the estimated future payout of the loss and loss adjustment expenses reserves. Any underwriting loss at inception of a retroactive reinsurance contract is recognised immediately.
	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.
	Reinsurance premiums ceded
	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 December 31, 2013, 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 and reserves for losses incurred but not yet reported (“IBNR reserves”). Case reserves are established for losses that have been reported, but not yet paid, based on loss reports from brokers and ceding companies. 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 developments on loss and loss adjustment expenses which 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 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 consolidated statements of income (loss) in the period in which they become known.
	Deposit liabilities
	Certain contracts do not transfer sufficient insurance risk and are accounted for using the deposit method of accounting. Management exercises judgment in determining whether contracts contain 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 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 consolidated statements of income (loss).
	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 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 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 consolidated balance sheet. Changes in the fair value of these contracts are recorded in net investment income in the consolidated statement of income.
	Investments
	Derivative instruments within our investment assets managed by our investment manager Third Point LLC, are recorded in the consolidated balance sheets at fair value, with changes in fair values and realized gains and losses recognised in net investment income in the consolidated statements of income (loss).
	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 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 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.
	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 granted that contain both a service and performance condition, the Company recognizes share compensation expense only for the portion of the options that are considered probable of being exercised. Share compensation for share purchase options considered probable of being exercised is expensed over the service (vesting) period on a graded vesting basis. The probability of share purchase options being exercised is evaluated at each reporting period.  When the share purchase options are considered probable of being exercised, the Company records a catch up of share compensation expense from the grant date (service inception date for existing options) to the current reporting period end based on the fair value of the options at the grant date.
	The Company measures grant date fair value for restricted share awards 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 certain warrant contracts issued to its Founders in conjunction with the initial capitalization of the Company, and which it may settle 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 consolidated statements of shareholders’ equity.
	Offering costs
	Offering costs incurred in connection with the initial capital raise of the Company and the IPO, which included underwriters’ fees, legal and accounting fees, printing and other fees have been deducted from the gross proceeds of the offering. The proceeds from the issuance of shares net of offering costs is included in additional paid in capital in the consolidated statements of shareholders’ equity.
	Foreign currency transactions
	The Company’s functional currency is the U.S. dollar. Transactions in foreign currencies are recorded in U.S. dollars at the exchange rate in effect on the transaction date. Monetary assets and liabilities in foreign currencies are translated at the exchange rates in effect at the reporting date and foreign exchange gains and losses are included in the consolidated statements of income (loss).
	Income taxes and uncertain tax positions
	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 pursuant to the Tax Assurance Certificates issued to such entities pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966, as amended.
	As of December 31, 2013, the Company did not have any uncertain tax positions.
	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 consolidated balance sheets. The Company records the portion of income attributable to non-controlling interests as a separate line within the consolidated statements of income (loss).
	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 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.
	During the fourth quarter of 2013, the Company determined that it had incorrectly calculated diluted earnings per share for the prior periods, which resulted in an understatement of diluted earnings per share. Basic earnings per share was correctly presented for the prior periods. The accompanying consolidated financial statements for the years ended December 31, 2013 and 2012 and for the period from October 6, 2011 (incorporation date) to December 31, 2011 correctly present diluted earnings per share and the weighted average number of dilutive shares outstanding. The following tables summarize the correct diluted earnings per share amounts and weighted average number of dilutive shares outstanding amounts for the prior periods.

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 consolidated statements of income (loss) 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 consolidated statements of income (loss).
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 results and certain general and administrative expenses related to its corporate activities.
Recently issued accounting standards
Issued and effective as of December 31, 2013
In January 2013, the FASB issued Accounting Standards Update No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities (ASU 2013-01). The objective of ASU 2013-01 is to address implementation issues about the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amendments clarify that the scope of ASU 2011-11 applies to derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. Entities with other types of financial assets and financial liabilities subject to a master netting arrangement or similar agreement also are affected because these amendments make them no longer subject to the disclosure requirements in ASU 2011-11. ASU 2013-01 is effective for interim and annual periods beginning on or after January 1, 2013. The Company has included the required disclosures in Note 9 of notes to consolidated financial statements.
In February 2013, the FASB issued Accounting Standard Update No. 2013-02, Comprehensive Income (ASU 2013-02). The objective of ASU 2013-02 is to improve the reporting of reclassifications out of other comprehensive income. ASU 2013-02 is effective for periods subsequent to December 15, 2012. The adoption of this guidance had no impact on the Company’s consolidated financial statements.
Issued but not yet effective as of December 31, 2013
In June 2013, the FASB issued Accounting Standards Update No. 2013-08, Financial Services - Investment Companies - Amendments to the Scope, Measurement, and Disclosure Requirements (ASU 2013-08). The amendments in this update change the assessment of whether an entity is an investment company by developing a new two-tiered approach for that assessment, which requires an entity to possess certain fundamental characteristics while allowing judgment in assessing other typical characteristics. The new approach requires an entity to assess all of the characteristics of an investment company and consider its purpose and design to determine whether it is an investment company. ASU 2013-08 is effective prospectively for periods subsequent to December 15, 2013. Early adoption is prohibited. The Company is currently evaluating the impact of this guidance; however, it is not expected to have a material impact on the Company's consolidated financial statements.

	Reinsurance premiums ceded
	The Company from time to time purchases retrocessional coverage for one or more of the following reasons: to manage its overall exposure, to reduce its net liability on individual risks, to obtain additional underwriting capacity and to balance its underwriting portfolio. Additionally, retrocession can be used as a mechanism to share the risks and rewards of business written and therefore can be used as a tool to align the Company’s interests with those of its counterparties. The Company currently has coverage that provides for recovery of a portion of loss and loss adjustment expenses incurred on one crop contract. Loss and loss adjustment expenses recoverable from the retrocessionaires are recorded as assets. For the year ended December 31, 2013, loss and loss adjustment expenses incurred and reported on the consolidated statements of income (loss) are net of loss and loss expenses recovered of $9.3 million. Retrocession contracts do not relieve the Company from its obligations to the insureds. Failure of retrocessionaires to honor their obligations could result in losses to the Company. As of December 31, 2013, the Company had loss and loss adjustment expenses recoverable of $9.3 million with one retrocessionaire who was rated “A (Excellent)” by A.M. Best Company. The Company regularly evaluates the financial condition of its retrocessionaires to assess the ability of the retrocessionaires to honor their obligations.

	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.
	The fair values of investments are estimated using prices obtained from either third-party pricing services or dealer quotes. The methodology for valuation is generally determined based on the investment's asset class as per the Company's Investment Manager valuation policy.  For investments that the Company is unable to obtain fair values from a pricing service or broker, 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 December 31, 2013, securities valued at $483.2 million (December 31, 2012 - $248.4 million), representing 33.1% (December 31, 2012 – 26.5%) of investments in securities and commodities, and $41.0 million (December 31, 2012 - $68.8 million), representing 73.1% (December 31, 2012 – 39.0%) of securities sold, not yet purchased, are valued based on dealer 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, as determined by the Company's Investment Manager. Valuation techniques used by the Company's Investment Manager 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, the Company or the Company’s Investment Manager may employ third party valuation firms to conduct separate valuations of such private securities. The third party valuation firms provide the Company or the Company’s Investment Manager with a written report documenting their recommended valuation as of the determination date for the specified investments.
	As of December 31, 2013, the Company had $3.3 million (December 31, 2012 - $2.8 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. 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 derivatives are recorded at fair value, and are included in the consolidated balance sheet 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 counterparty 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 its 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 consolidated balance sheets at fair value, with the offset recorded in net investment income in the consolidated statements of income (loss).  These contracts are valued on the basis of models developed by the Company, which approximates fair value.
	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 dealer 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. Investors in these classes of ABS 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, investors 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 consolidated statements of income (loss).
	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 outside service providers.
	For the years ended December 31, 2013 and 2012, there were no changes in the valuation techniques as it relates to the above.
	Monetary assets and liabilities denominated in foreign currencies are translated at the closing rates of exchange. Transactions during the period are translated at the rate of exchange prevailing on the date of the transaction. The Company does not isolate that 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 consolidated statements of income (loss).
	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 December 31, 2013 and 2012:

Securities purchased under an agreement to sell	'
	Securities purchased under an agreement to sell
	The Company may enter into repurchase and reverse repurchase agreements with financial institutions in which the financial institution agrees to resell or repurchase and the Company agrees to repurchase or resell such securities at a mutually agreed price upon maturity. As of December 31, 2013, the Company held outstanding reverse repurchase agreements valued at $38.1 million (December 31, 2012 - $60.4 million). As of December 31, 2013, the total value of securities received as collateral by the Company was $37.6 million (December 31, 2012 - $60.0 million). As the Company held only reverse repurchase agreements as of December 31, 2013, these positions are not impacted by master netting agreements. Interest expense and income related to these transactions are included in interest payable and receivable in the consolidated balance sheets. For the year ended December 31, 2013, foreign currency gains of $1.9 million (2012 – gains of $0.6 million) on reverse repurchase agreements are included in net investment income in the consolidated statements of income (loss). Generally, reverse repurchase agreements mature within 30 to 90 days.

Financial Instruments Sold, Not yet Purchased, at Fair Value [Abstract]	'
Securities sold, not yet purchased, at fair value	'
	Securities sold, not yet purchased, at fair value
	Securities sold, not yet purchased are securities that the Company has sold, but does not own, in anticipation of a decline in the fair value of the security. The Company’s risk is that the value of the security will increase rather than decline. Consequently, the settlement amount of the liability for securities sold, not yet purchased may exceed the amount recorded in the consolidated balance sheet as the Company is obligated to purchase the securities sold, not yet purchased in the market at prevailing prices to settle its obligations. To sell a security sold, not yet purchased, the Company needs to borrow the security for delivery to the buyer. On each day that the transaction is open, the liability for the obligation to replace the borrowed security is marked-to-market and an unrealized gain or loss is recorded. At the time that the transaction is closed, the Company realizes a gain or loss equal to the difference between the price at which the security was sold and the cost of replacing the borrowed security. While the transaction is open, the Company will also incur an expense for any dividends or interest that will be paid to the lender of the securities.

	The $4.7 million decrease in prior years' reserves reflects $1.3 million of favorable loss experience on several contracts and $3.4 million related to premium estimate decreases, primarily related to one crop contract. The reduction in loss and loss adjustment expense reserves related to premium estimates was accompanied by an equal decrease in the premium written and earned for that contract, resulting in a minimal impact to net underwriting income.

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 Agreement, which are included in net investment income in the consolidated statements of income (loss) for the years ended December 31, 2013 and 2012 are as follows:

	The Company's authorized share capital of $33.0 million is comprised of 300,000,000 common shares with a par value of $0.10 each and 30,000,000 preference shares with a par value of $0.10 each. As of December 31, 2013, 103,888,916 common shares were issued and outstanding. No preference shares have been issued to date.
	On August 20, 2013, the Company completed an IPO of 24,832,484 common shares at a purchase price of $12.50 per share. The net proceeds of the offering were $286.0 million, after deducting offering costs.
	Warrants
	The Company’s Founders and an advisor provided insurance industry expertise, resources and relationships to ensure that the Company would be fully operational with key management in place in time for the January 2012 underwriting season. In consideration of these commitments, the Company reserved for issuance to the Founders and an advisor warrants to purchase, in the aggregate, up to 4.0% (Founders 3.5% and an advisor 0.5%) of the diluted shares (up to a maximum of $1 billion of subscribed shares) provided that the Founders and the advisor will not be issued any warrants for common shares issued in consideration for any capital raised by the Company in excess of $1 billion. The following is a summary of warrants as of December 31, 2013:

	Advisor	$	10	581,295	2,171
				4,651,163	$	17,374
	The warrants were subject to a performance condition that was met as a result of the IPO. Prior to the IPO, 3,648,006 of the warrants outstanding had met the performance condition. After the IPO, the remaining 1,003,157 warrants met the performance condition. For the year ended December 31, 2013, the Company recorded $3.7 million related to the additional warrants that met the performance condition as a result of the IPO. These amounts have been recorded as a component of capital raise costs in additional paid in capital resulting in no net impact to total shareholders’ equity.
	The warrants expire 10 years from the date of issuance, December 22, 2011, and will be exercisable at a price per share of $10.00, which is equal to the price per share paid by investors in the initial private offering.

	On July 15, 2013, the Third Point Reinsurance Ltd. 2103 Omnibus Incentive Plan (“Omnibus Plan”) was approved by the Board of Directors and subsequently on August 2, 2013 by the Shareholders of the Company. An aggregate of 21,627,906 common shares were made available under the Omnibus Plan. This number of shares includes the shares available under the Third Point Reinsurance Limited Share Incentive Plan ("Share Incentive Plan"). Awards under the Omnibus Plan may be made in the form of performance awards, restricted shares, restricted share units, share options, share appreciation rights and other share-based awards.
	As of December 31, 2013, 10,613,975 of the Company's common shares were available for future issuance under the equity incentive compensation plans.
	Share based compensation expense of $9.8 million for the year ended December 31, 2013 (2012 - $6.4 million) was included in general and administrative expenses, which included $2.1 million related to additional expense incurred due to the performance condition having been met as a result of the IPO.
	As of December 31, 2013, the Company had $23.8 million of unamortized share compensation expense which is expected to be amortized over a weighted average period of 2.0 years.
	(a)	Management and director options
	The management options issued under the Share Incentive Plan were subject to a service and performance condition. The service condition will be met with respect to 20% of the management options on each of the first five anniversary dates following the grant date of the management options. The performance condition with respect to the management options was met as a result of the IPO. Prior to the IPO, 8,572,594 of the management options outstanding had met the performance condition. After the IPO, the remaining 2,357,633 management options had met the performance condition.
	The director options contain only a service condition that will be met with respect to 20% of the director options on each of the five anniversary dates following the grant date of the director options. On November 6, 2013, the director options were modified so that a total of 60% of the outstanding options vested on that date and the remaining 40% of the director options were forfeited. These forfeited options were replaced with restricted share awards.
	The management and director options activity for the years ended December 31, 2013 and 2012 were as follows:
		Number of		Weighted

	Balances as of December 31, 2013	10,981,075		$	13.23
	The fair value of share options issued were estimated on the grant date using the Black-Scholes option-pricing model. The estimated share price used for purposes of determining the fair value of share options that were granted in the second quarter of 2013 (prior to the IPO) was $10.89 (2012 - $10.00). The volatility assumption used of 21.95% (2012 - 31.25%) was based on the average estimated volatility of a reinsurance company peer group. The other assumptions used in the option-pricing model were as follows: risk free interest rate of 1.23% (2012 - 1.9%), expected life of 6.5 years (2012 - 10.0 years) and a 0.0% dividend yield (2012 - 0.0%). As of December 31, 2013, the weighted average remaining contractual term for options outstanding was 8.1 years (2012 - 9.0 years).
	The following table summarizes information about the Company’s management and director share options outstanding as of December 31, 2013:

	The aggregate intrinsic value of options outstanding and options exercisable as of December 31, 2013 was $61.5 million and $17.6 million, respectively (2012 - $5.9 million and $0.5 million, respectively).

	a)	Pine Brook Road Partners, LLC and Narragansett Bay Insurance Company
	Third Point Re entered into a quota share reinsurance agreement with Narragansett Bay Insurance Company (“Narragansett Bay”) effective December 31, 2012, which was renewed on December 31, 2013.

	b)	TP Lux Holdco LP
	Third Point Re entered into a limited partnership agreement, as one of the limited partners of TP Lux Holdco LP (the “Cayman HoldCo”), which is also an affiliate of the Investment Manager. The Cayman HoldCo was formed as a limited partnership under the laws of the Cayman Islands and invests and holds debt and equity interests in TP Lux HoldCo S.a.r.l, a Luxembourg private limited liability company (the “LuxCo”), which is also an affiliate of the Investment Manager.
	The LuxCo was established under the laws of the Grand-Duchy of Luxembourg and its principle objective is to act as a collective investment vehicle to purchase Euro debt and equity investments. Third Point Re invests in the Cayman HoldCo alongside other investment funds managed by the Investment Manager. As of December 31, 2013 and 2012, Third Point Re held approximately a 10% interest in the Cayman Holdco. As a result, Third Point Re accounts for its investment in the limited partnership under the variable interest model, in which Third Point Re is not the primary beneficiary, at fair value in the consolidated balance sheets and records the change in the fair value in the consolidated statements of income (loss).
	As of December 31, 2013, the estimated fair value of the investment in the limited partnership was $29.3 million (December 31, 2012 - $91.3 million).  The valuation policy with respect to this investment in a limited partnership is further described in Note 5.

Guarantees [Abstract]	'
Financial instruments with off-balance sheet risk or concentrations of credit risk	'
	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 recognised in the consolidated balance sheets.
	Securities sold, not yet purchased are recorded as liabilities in the 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 consolidated balance sheets. The Company’s investments in securities 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 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 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.
	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. Cash collateral available to the Company to mitigate potential counterparty risk related to written credit default swaps amounted to $1.6 million as of December 31, 2013. Cash collateral received 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 December 31, 2013:
			Maximum Payout/ Notional Amount (by period of expiration)						Fair Value of Written Credit Derivatives (2)
	Credit Spreads on		0-5 years		5 years or		Total Written		Asset		Liability			Net Asset/(Liability)

	-1	As of December 31, 2013, 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.
	As of December 31, 2012, the Company sold protection on an index-reference obligation with a maximum potential payout amount of $0.4 million, a credit spread of 0.44% and maturity in 2046. The fair value of such protection sold totaled $0.2 million as of December 31, 2012.
	Concentrations of credit risk
	In addition to off-balance sheet risks related to specific financial instruments, the Company may be subject to concentration 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 December 31, 2013. 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 counterparty inherent in such contracts which are recognised in the consolidated balance sheets. As of December 31, 2013, the Company’s maximum counterparty credit risk exposure was $19.0 million (December 31, 2012 - $17.0 million).

	-1	Effective January 1, 2013, the Citibank facility was reduced from $250.0 million to $150.0 million.
	As of December 31, 2013, $127.3 million (December 31, 2012 - $60.9 million) of letters of credit, representing 42.4% (December 31, 2012 – 15.3% (based on total available facilities of $400 million)) of the total available facilities, had been drawn upon.

	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 consolidated statements of income (loss).
	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 formal or informal dispute resolution procedures.

	Statutory requirements
	The following is a summary of actual and required statutory capital and surplus and statutory net income as of December 31, 2013 and 2012 and for the years then ended:
		31-Dec-13		31-Dec-12
		($ in thousands)
	Actual statutory capital	$	1,303,487	$	824,453
	Required statutory capital and surplus	526,933		116,416
	Statutory net income	229,974		101,347
	Under the Bermuda Insurance Act, 1978 and related regulations, Third Point Re is subject to capital requirements calculated using the Bermuda Solvency and Capital Requirement, or BSCR model, which is a standardized statutory risk-based capital model used to measure the risk associated with Third Point Re’s assets, liabilities and premiums. Third Point Re’s required statutory capital and surplus under the BSCR model is referred to as the enhanced capital requirement, or ECR. Third Point Re is required to calculate and submit the ECR to the Bermuda Monetary Authority, or the BMA, annually. Following receipt of the submission of Third Point Re’s ECR the BMA has the authority to impose additional capital requirements (capital add-ons) if it deems necessary. If a company fails to maintain or meet its ECR, the BMA may take various degrees of regulatory action. As of December 31, 2013 and 2012, Third Point Re met its ECR.
	The principal difference between statutory capital and surplus and shareholders' equity presented in accordance with GAAP is deferred acquisition costs and prepaid expenses, which are non-admitted assets for statutory purposes.
	Third Point Re is also required under its Class 4 license to maintain a minimum liquidity ratio whereby the value of its relevant assets is not less than 75% of the amount of its relevant liabilities for general business. As of December 31, 2013 and 2012, Third Point Re met the minimum liquidity ratio requirement.
	Third Point Re may declare dividends subject to it continuing to meet its solvency and capital requirements, which includes continuing to hold statutory capital and surplus equal to or exceeding its ECR. Third Point Re is prohibited from declaring or paying in any fiscal year dividends of more than 25% of its prior year's statutory capital and surplus unless Third Point Re files with the BMA a signed affidavit by at least two members of the Board of Directors attesting that a dividend would not cause the company to fail to meet its relevant margins. As of December 31, 2013, Third Point Re could pay dividends in 2014 of approximately $325.9 million (2012 - $206.1 million) without providing an affidavit to the BMA.

Accounting Policies [Abstract]

'

Use of estimates

'

Use of estimates

The preparation of 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 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 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.

Premium revenue recognition

'

Premium revenue recognition

The Company estimates the ultimate premiums for the entire contract period and records this estimate at the inception of the contract, to the extent that the amount of written premium is estimable. 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.

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 reinsurance contracts, where the Company has evaluated and concluded that risk transfer has occured, are earned at the inception of the contract, as all of the underlying loss events covered by these contracts occurred in the past. Any underwriting profit at inception of a retroactive reinsurance contract is deferred and recognised over the estimated future payout of the loss and loss adjustment expenses reserves. Any underwriting loss at inception of a retroactive reinsurance contract is recognised immediately.

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.

Reinsurance premiums ceded

'

Reinsurance premiums ceded

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 December 31, 2013, 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 and reserves for losses incurred but not yet reported (“IBNR reserves”). Case reserves are established for losses that have been reported, but not yet paid, based on loss reports from brokers and ceding companies. 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 developments on loss and loss adjustment expenses which 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 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 consolidated statements of income (loss) in the period in which they become known.

Deposit liabilities

'

Deposit liabilities

Certain contracts do not transfer sufficient insurance risk and are accounted for using the deposit method of accounting. Management exercises judgment in determining whether contracts contain 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 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 consolidated statements of income (loss).

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 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 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 consolidated balance sheet. Changes in the fair value of these contracts are recorded in net investment income in the consolidated statement of income.

Investments

Derivative instruments within our investment assets managed by our investment manager Third Point LLC, are recorded in the consolidated balance sheets at fair value, with changes in fair values and realized gains and losses recognised in net investment income in the consolidated statements of income (loss).

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 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 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.

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 granted that contain both a service and performance condition, the Company recognizes share compensation expense only for the portion of the options that are considered probable of being exercised. Share compensation for share purchase options considered probable of being exercised is expensed over the service (vesting) period on a graded vesting basis. The probability of share purchase options being exercised is evaluated at each reporting period.  When the share purchase options are considered probable of being exercised, the Company records a catch up of share compensation expense from the grant date (service inception date for existing options) to the current reporting period end based on the fair value of the options at the grant date.

The Company measures grant date fair value for restricted share awards 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 certain warrant contracts issued to its Founders in conjunction with the initial capitalization of the Company, and which it may settle 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 consolidated statements of shareholders’ equity.

Offering costs

'

Offering costs

Offering costs incurred in connection with the initial capital raise of the Company and the IPO, which included underwriters’ fees, legal and accounting fees, printing and other fees have been deducted from the gross proceeds of the offering. The proceeds from the issuance of shares net of offering costs is included in additional paid in capital in the consolidated statements of shareholders’ equity.

Foreign currency transactions

'

Foreign currency transactions

The Company’s functional currency is the U.S. dollar. Transactions in foreign currencies are recorded in U.S. dollars at the exchange rate in effect on the transaction date. Monetary assets and liabilities in foreign currencies are translated at the exchange rates in effect at the reporting date and foreign exchange gains and losses are included in the consolidated statements of income (loss).

Income taxes and uncertain tax positions

'

Income taxes and uncertain tax positions

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 pursuant to the Tax Assurance Certificates issued to such entities pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966, as amended.

As of December 31, 2013, the Company did not have any uncertain tax positions.

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 consolidated balance sheets. The Company records the portion of income attributable to non-controlling interests as a separate line within the consolidated statements of income (loss).

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 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.

During the fourth quarter of 2013, the Company determined that it had incorrectly calculated diluted earnings per share for the prior periods, which resulted in an understatement of diluted earnings per share. Basic earnings per share was correctly presented for the prior periods. The accompanying consolidated financial statements for the years ended December 31, 2013 and 2012 and for the period from October 6, 2011 (incorporation date) to December 31, 2011 correctly present diluted earnings per share and the weighted average number of dilutive shares outstanding. The following tables summarize the correct diluted earnings per share amounts and weighted average number of dilutive shares outstanding amounts for the prior periods.

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 consolidated statements of income (loss) 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 consolidated statements of income (loss).

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 results and certain general and administrative expenses related to its corporate activities.

Recently issued accounting standards

Recently issued accounting standards

Issued and effective as of December 31, 2013

In January 2013, the FASB issued Accounting Standards Update No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities (ASU 2013-01). The objective of ASU 2013-01 is to address implementation issues about the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amendments clarify that the scope of ASU 2011-11 applies to derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. Entities with other types of financial assets and financial liabilities subject to a master netting arrangement or similar agreement also are affected because these amendments make them no longer subject to the disclosure requirements in ASU 2011-11. ASU 2013-01 is effective for interim and annual periods beginning on or after January 1, 2013. The Company has included the required disclosures in Note 9 of notes to consolidated financial statements.

In February 2013, the FASB issued Accounting Standard Update No. 2013-02, Comprehensive Income (ASU 2013-02). The objective of ASU 2013-02 is to improve the reporting of reclassifications out of other comprehensive income. ASU 2013-02 is effective for periods subsequent to December 15, 2012. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

Issued but not yet effective as of December 31, 2013

In June 2013, the FASB issued Accounting Standards Update No. 2013-08, Financial Services - Investment Companies - Amendments to the Scope, Measurement, and Disclosure Requirements (ASU 2013-08). The amendments in this update change the assessment of whether an entity is an investment company by developing a new two-tiered approach for that assessment, which requires an entity to possess certain fundamental characteristics while allowing judgment in assessing other typical characteristics. The new approach requires an entity to assess all of the characteristics of an investment company and consider its purpose and design to determine whether it is an investment company. ASU 2013-08 is effective prospectively for periods subsequent to December 15, 2013. Early adoption is prohibited. The Company is currently evaluating the impact of this guidance; however, it is not expected to have a material impact on the Company's consolidated financial statements.
