Basis of Presentation and Significant Accounting Policies [Text Block]	'
	2. Significant Accounting Policies
	The Company's Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. The Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions have been eliminated.
	The preparation of financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While Management believes that the amounts included in the Condensed Consolidated Financial Statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company's principal estimates include:
	• Unpaid losses and loss expenses;
	• Policy benefits for life and annuity contracts;
	• Gross and net premiums written and net premiums earned;
	• Recoverability of deferred acquisition costs;
	• Recoverability of deferred tax assets;
	• Valuation of goodwill and intangible assets; and
	• Valuation of certain assets and derivative financial instruments that are measured using significant unobservable inputs.
	In the opinion of Management, all adjustments (which include normal recurring adjustments) necessary for a fair presentation of results for the interim periods have been made. As the Company's reinsurance operations are exposed to low-frequency, high-severity risk events, some of which are seasonal, results for certain interim periods may include unusually low loss experience, while results for other interim periods may include significant catastrophic losses. Consequently, the Company's results for interim periods are not necessarily indicative of results for the full year. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.

	3. Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board issued updated guidance on the accounting for investments in affordable housing projects that qualify for low-income housing tax credits by entities that manage or invest in such projects. The update modifies the conditions that an entity must meet to elect the effective yield or proportional amortization method to account for such investments. The guidance is effective for interim and annual periods beginning after December 15, 2014, with early adoption permitted. The Company does not expect the adoption of this guidance to have a significant impact on its Consolidated Financial Statements or disclosures.

	4. Fair Value
	(a) Fair Value of Financial Instrument Assets
	The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value by maximizing the use of observable inputs and minimizing the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about what market participants would use in pricing the asset or liability based on the best information available in the circumstances. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement.
	The Company determines the appropriate level in the hierarchy for each financial instrument that it measures at fair value. In determining fair value, the Company uses various valuation approaches, including market, income and cost approaches. The hierarchy is broken down into three levels based on the observability of inputs as follows:
	• Level 1 inputs—Unadjusted, quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.
	The Company's financial instruments that it measures at fair value using Level 1 inputs generally include: equities and real estate investment trusts listed on a major exchange, exchange traded funds and exchange traded derivatives, including futures that are actively traded.
	• Level 2 inputs—Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets and significant directly or indirectly observable inputs, other than quoted prices, used in industry accepted models.
	The Company's financial instruments that it measures at fair value using Level 2 inputs generally include: U.S. government issued bonds; U.S. government sponsored enterprises bonds; U.S. state, territory and municipal entities bonds; non-U.S. sovereign government, supranational and government related bonds consisting primarily of bonds issued by non-U.S. national governments and their agencies, non-U.S. regional governments and supranational organizations; investment grade and high yield corporate bonds; catastrophe bonds; mortality bonds; asset-backed securities; mortgage-backed securities; certain equities traded on foreign exchanges; certain fixed income mutual funds; foreign exchange forward contracts; over-the-counter derivatives such as foreign currency option contracts, credit default swaps, interest rate swaps and to-be-announced mortgage-backed securities (TBAs).
	• Level 3 inputs—Unobservable inputs.
	The Company's financial instruments that it measures at fair value using Level 3 inputs generally include: inactively traded fixed maturities including U.S. state, territory and municipal bonds; privately issued corporate securities; special purpose financing asset-backed bonds; unlisted equities; real estate and certain other mutual fund investments; inactively traded weather derivatives; notes and loan receivables, notes securitizations, annuities and residuals, private equities and longevity and other total return swaps.
	The Company's policy is to recognize transfers between the hierarchy levels at the beginning of the period.
	The Company's financial instruments measured at fair value include investments classified as trading securities, certain other invested assets and the segregated investment portfolio underlying the funds held – directly managed account. At March 31, 2014 and December 31, 2013, the Company's financial instruments measured at fair value were classified between Levels 1, 2 and 3 as follows (in thousands of U.S. dollars):

At March 31, 2014 and December 31, 2013, the aggregate carrying amounts of items included in Other invested assets that the Company did not measure at fair value were $189.2 million and $185.8 million, respectively, which related to the Company's investments that are accounted for using the cost method of accounting or equity method of accounting.
In addition to the investments underlying the funds held – directly managed account held at fair value of $596.3 million and $561.3 million at March 31, 2014 and December 31, 2013, respectively, the funds held – directly managed account also included cash and cash equivalents, carried at fair value, of $37.1 million and $84.8 million, respectively, and accrued investment income of $7.5 million and $6.7 million, respectively. At March 31, 2014 and December 31, 2013, the aggregate carrying amounts of items included in the funds held – directly managed account that the Company did not measure at fair value were $123.5 million and $133.0 million, respectively, which primarily related to other assets and liabilities held by Colisée Re related to the underlying business, which are carried at cost (see Note 5 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013).
At March 31, 2014 and December 31, 2013, substantially all of the accrued investment income in the Condensed Consolidated Balance Sheets relate to the Company's investments and the investments underlying the funds held – directly managed account for which the fair value option was elected.
During the three months ended March 31, 2014 and 2013, there were no transfers between Level 1 and Level 2.
Disclosures about the fair value of financial instruments that the Company does not measure at fair value exclude insurance contracts and certain other financial instruments. At March 31, 2014 and December 31, 2013, the fair values of financial instrument assets recorded in the Condensed Consolidated Balance Sheets not described above, approximate their carrying values.
The reconciliations of the beginning and ending balances for all financial instruments measured at fair value using Level 3 inputs for the three months ended March 31, 2014 and 2013, were as follows (in thousands of U.S. dollars):

The tables above do not include financial instruments that are measured using unobservable inputs (Level 3) where the unobservable inputs were obtained from external sources and used without adjustment. These financial instruments include mutual fund investments (included within equities) and certain insurance-linked securities (included within other invested assets).
The Company has established a Valuation Committee which is responsible for determining the Company's invested asset valuation policy and related procedures, for reviewing significant changes in the fair value measurements of securities classified as Level 3 from period to period, and for reviewing in accordance with the invested asset valuation policy an independent internal peer analysis that is performed on the fair value measurements of significant securities that are classified as Level 3. The Valuation Committee is comprised of members of the Company's senior management team and meets on a quarterly basis. The Company's invested asset valuation policy is monitored by the Company's Audit Committee of the Board of Directors (Board) and approved annually by the Company's Risk and Finance Committee of the Board.
Changes in the fair value of the Company's financial instruments subject to the fair value option during the three months ended March 31, 2014 and 2013 were as follows (in thousands of U.S. dollars):
	For the three				For the three
	months ended				months ended

Fixed maturities and short-term investments	$	119,799			$	-71,670

Total	$	131,902			$	-32,481
Substantially all of the above changes in fair value are included in the Condensed Consolidated Statements of Operations under the caption Net realized and unrealized investment gains.
The following methods and assumptions were used by the Company in estimating the fair value of each class of financial instrument recorded in the Condensed Consolidated Balance Sheets. There have been no material changes in the Company's valuation techniques during the periods presented.
Fixed maturities
• U.S. government and government sponsored enterprises—U.S. government and government sponsored enterprises securities consist primarily of bonds issued by the U.S. Treasury, corporate debt securities issued by the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, the Federal Home Loan Bank and the Private Export Funding Corporation. These securities are generally priced by independent pricing services. The independent pricing services may use actual transaction prices for securities that have been actively traded. For securities that have not been actively traded, each pricing source has its own proprietary method to determine the fair value, which may incorporate option adjusted spreads (OAS), interest rate data and market news. The Company generally classifies these securities in Level 2.
• U.S. states, territories and municipalities—U.S. states, territories and municipalities securities consist primarily of bonds issued by U.S. states, territories and municipalities and the Federal Home Loan Mortgage Corporation. These securities are generally priced by independent pricing services using the techniques described for U.S. government and government sponsored enterprises above. The Company generally classifies these securities in Level 2. Certain of the bonds that are issued by municipal housing authorities and the Federal Home Loan Mortgage Corporation are not actively traded and are priced based on internal models using unobservable inputs. Accordingly, the Company classifies these securities in Level 3. The significant unobservable input used in the fair value measurement of these U.S. states, territories and municipalities securities classified as Level 3 is credit spreads. A significant increase (decrease) in credit spreads in isolation could result in a significantly lower (higher) fair value measurement.
• Non-U.S. sovereign government, supranational and government related—Non-U.S. sovereign government, supranational and government related securities consist primarily of bonds issued by non-U.S. national governments and their agencies, non-U.S. regional governments and supranational organizations. These securities are generally priced by independent pricing services using the techniques described for U.S. government and government sponsored enterprises above. The Company generally classifies these securities in Level 2.
• Corporate—Corporate securities consist primarily of bonds issued by U.S. and foreign corporations covering a variety of industries and issuing countries. These securities are generally priced by independent pricing services and brokers. The pricing provider incorporates information including credit spreads, interest rate data and market news into the valuation of each security. The Company generally classifies these securities in Level 2. When a corporate security is inactively traded or the valuation model uses unobservable inputs, the Company classifies the security in Level 3.
• Asset-backed securities—Asset-backed securities primarily consist of bonds issued by U.S. and foreign corporations that are predominantly backed by student loans, automobile loans, credit card receivables, equipment leases, and special purpose financing. With the exception of special purpose financing, these asset-backed securities are generally priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. The Company generally classifies these securities in Level 2. Special purpose financing securities are generally inactively traded and are priced based on valuation models using unobservable inputs. The Company generally classifies these securities in Level 3. The significant unobservable inputs used in the fair value measurement of these asset-backed securities classified as Level 3 are prepayment speeds and credit spreads. Significant increases (decreases) in these prepayment speeds and credit spreads in isolation could result in a significantly lower (higher) fair value measurement.
• Residential mortgage-backed securities—Residential mortgage-backed securities primarily consist of bonds issued by the Government National Mortgage Association, the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, as well as private, non-agency issuers. These residential mortgage-backed securities are generally priced by independent pricing services and brokers. When current market trades are not available, the pricing provider or the Company will employ proprietary models with observable inputs including other trade information, prepayment speeds, yield curves and credit spreads. The Company generally classifies these securities in Level 2.
• Other mortgage-backed securities—Other mortgage-backed securities primarily consist of commercial mortgage-backed securities. These securities are generally priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. The Company generally classifies these securities in Level 2.
In general, the methods employed by the independent pricing services to determine the fair value of the securities that have not been actively traded involve the use of “matrix pricing” in which the independent pricing source applies the credit spread for a comparable security that has traded recently to the current yield curve to determine a reasonable fair value. The Company uses a pricing service ranking to consistently select the most appropriate pricing service in instances where it receives multiple quotes on the same security. When fair values are unavailable from these independent pricing sources, quotes are obtained directly from broker-dealers who are active in the corresponding markets. Most of the Company's fixed maturities are priced from the pricing services or dealer quotes. The Company will typically not make adjustments to prices received from pricing services or dealer quotes; however, in instances where the quoted external price for a security uses significant unobservable inputs, the Company will classify that security as Level 3. The methods used to develop and substantiate the unobservable inputs used are based on the Company's valuation policy and are dependent upon the facts and circumstances surrounding the individual investments which are generally transaction specific. The Company's inactively traded fixed maturities are classified as Level 3. For all fixed maturity investments, the bid price is used for estimating fair value.
To validate prices, the Company compares the fair value estimates to its knowledge of the current market and will investigate prices that it considers not to be representative of fair value. The Company also reviews an internally generated fixed maturity price validation report which converts prices received for fixed maturity investments from the independent pricing sources and from broker-dealers quotes and plots OAS and duration on a sector and rating basis. The OAS is calculated using established algorithms developed by an independent risk analytics platform vendor. The OAS on the fixed maturity price validation report are compared for securities in a similar sector and having a similar rating, and outliers are identified and investigated for price reasonableness. In addition, the Company completes quantitative analyses to compare the performance of each fixed maturity investment portfolio to the performance of an appropriate benchmark, with significant differences identified and investigated.
Short-term investments
Short-term investments are valued in a manner similar to the Company's fixed maturity investments and are generally classified in Level 2.
Equities
Equity securities include U.S. and foreign common and preferred stocks, real estate investment trusts, mutual funds and exchange traded funds. Equities, real estate investment trusts and exchange traded funds are generally classified in Level 1 as the Company uses prices received from independent pricing sources based on quoted prices in active markets. Equities classified as Level 2 are generally mutual funds invested in fixed income securities, where the net asset value of the fund is provided on a daily basis, and common stocks traded in inactive markets. Equities classified as Level 3 are generally mutual funds invested in securities other than the common stock of publicly traded companies, where the net asset value is not provided on a daily basis, and inactively traded common stocks. The significant unobservable inputs used in the fair value measurement of inactively traded common stocks classified as Level 3 include market return information, weighted using management's judgment, from comparable selected publicly traded companies in the same industry, in a similar region and of a similar size, including net income multiples, tangible book value multiples, comparable returns, revenue multiples, adjusted earnings multiples and projected return on equity ratios. Significant increases (decreases) in any of these inputs could result in a significantly higher (lower) fair value measurement. Significant unobservable inputs used in measuring the fair value measurement of inactively traded common stocks also include a liquidity discount. A significant increase (decrease) in the liquidity discount could result in a significantly lower (higher) fair value measurement.
To validate prices, the Company completes quantitative analyses to compare the performance of each equity investment portfolio to the performance of an appropriate benchmark, with significant differences identified and investigated.
Other invested assets
The Company's exchange traded derivatives, such as futures are generally classified as Level 1 as their fair values are quoted prices in active markets. The Company's foreign exchange forward contracts, foreign currency option contracts, credit default swaps, interest rate swaps and TBAs are generally classified as Level 2 within the fair value hierarchy and are priced by independent pricing services.
Included in the Company's Level 3 classification, in general, are certain inactively traded weather derivatives, notes and loan receivables, notes securitizations, annuities and residuals, private equities and longevity and other total return swaps. For Level 3 instruments, the Company will generally (i) receive a price based on a manager's or trustee's valuation for the asset; (ii) develop an internal discounted cash flow model to measure fair value; or (iii) use market return information, adjusted if necessary and weighted using management's judgment, from comparable selected publicly traded equity funds, in a similar region and of a similar size. Where the Company receives prices from the manager or trustee, these prices are based on the manager's or trustee's estimate of fair value for the assets and are generally audited on an annual basis. Where the Company develops its own discounted cash flow models, the inputs will be specific to the asset in question, based on appropriate historical information, adjusted as necessary, and using appropriate discount rates. The significant unobservable inputs used in the fair value measurement of other invested assets classified as Level 3 include credit spreads, prepayment speeds, constant default rates, gross revenue to fair value ratios, net income multiples, effective yields, tangible book value multiples and other valuation ratios. Significant increases (decreases) in any of these inputs in isolation could result in a significantly lower (higher) fair value measurement. Significant unobservable inputs used in the fair value measurement of other invested assets classified as Level 3 also include an assessment of the recoverability of intangible assets and market return information, weighted using management's judgment, from comparable selected publicly traded companies in the same industry, in a similar region and of a similar size. Significant increase (decrease) in these inputs in isolation could result in a significantly higher (lower) fair value measurement. As part of the Company's modeling to determine the fair value of an investment, the Company considers counterparty credit risk as an input to the model, however, the majority of the Company's counterparties are investment grade rated institutions and the failure of any one counterparty would not have a significant impact on the Company's consolidated financial statements.
To validate prices, the Company will compare them to benchmarks, where appropriate, or to the business results generally within that asset class and specifically to those particular assets.
Funds held – directly managed
The segregated investment portfolio underlying the funds held – directly managed account is comprised of fixed maturities and other invested assets which are fair valued on a basis consistent with the methods described above. Substantially all fixed maturities and short-term investments within the funds held – directly managed account are classified as Level 2 within the fair value hierarchy.
The other invested assets within the segregated investment portfolio underlying the funds held – directly managed account, which are classified as Level 3 investments, are primarily real estate mutual fund investments carried at fair value. For the real estate mutual fund investments, the Company receives a price based on the real estate fund manager's valuation for the asset and further adjusts the price, if necessary, based on appropriate current information on the real estate market. Significant increases (decreases) to the adjustment to the real estate fund manager's valuation could result in a significantly lower (higher) fair value measurement.
To validate prices within the segregated investment portfolio underlying the funds held – directly managed account, the Company utilizes the methods described above.
(b) Fair Value of Financial Instrument Liabilities
At March 31, 2014 and December 31, 2013, the fair values of financial instrument liabilities recorded in the Condensed Consolidated Balance Sheets approximate their carrying values, with the exception of the debt related to senior notes (Senior Notes) and the debt related to capital efficient notes (CENts).
The methods and assumptions used by the Company in estimating the fair value of each class of financial instrument liability recorded in the Condensed Consolidated Balance Sheets for which the Company does not measure that instrument at fair value were as follows:
• the fair value of the Senior Notes was calculated based on discounted cash flow models using observable market yields and contractual cash flows based on the aggregate principal amount outstanding of $250 million from PartnerRe Finance A LLC and $500 million from PartnerRe Finance B LLC at March 31, 2014 and December 31, 2013; and
• the fair value of the CENts was calculated based on discounted cash flow models using observable market yields and contractual cash flows based on the aggregate principal amount outstanding of $63 million from PartnerRe Finance II Inc. at March 31, 2014 and December 31, 2013.
The carrying values and fair values of the Senior Notes and CENts at March 31, 2014 and December 31, 2013 were as follows (in thousands of U.S. dollars):
	31-Mar-14								31-Dec-13
	Carrying Value				Fair Value				Carrying Value				Fair Value
Debt related to senior notes⁽¹⁾	$	750,000			$	868,989			$	750,000			$	844,331
Debt related to capital efficient notes ⁽²⁾		63,384				62,780				63,384				61,094

(1) PartnerRe Finance A LLC and PartnerRe Finance B LLC, the issuers of the Senior Notes, do not meet consolidation requirements under U.S. GAAP. Accordingly, the Company shows the related intercompany debt of $750 million in its Condensed Consolidated Balance Sheets at March 31, 2014 and December 31, 2013.
(2) PartnerRe Finance II Inc., the issuer of the CENts, does not meet consolidation requirements under U.S. GAAP. Accordingly, the Company shows the related intercompany debt of $71 million in its Condensed Consolidated Balance Sheets at March 31, 2014 and December 31, 2013.
At March 31, 2014 and December 31, 2013, the Company's debt related to the Senior Notes and CENts was classified as Level 2 in the fair value hierarchy.
Disclosures about the fair value of financial instrument liabilities exclude insurance contracts and certain other financial instruments.

	5. Derivatives
	The Company's derivative instruments are recorded in the Condensed Consolidated Balance Sheets at fair value, with changes in fair value recognized in either net foreign exchange gains and losses or net realized and unrealized investment gains and losses in the Condensed Consolidated Statements of Operations or accumulated other comprehensive income or loss in the Condensed Consolidated Balance Sheets, depending on the nature of the derivative instrument. The Company's objectives for holding or issuing these derivatives are as follows:
	Foreign Exchange Forward Contracts
	The Company utilizes foreign exchange forward contracts as part of its overall currency risk management and investment strategies. From time to time, the Company also utilizes foreign exchange forward contracts to hedge a portion of its net investment exposure resulting from the translation of its foreign subsidiaries and branches whose functional currency is other than the U.S. dollar.
	Foreign Currency Option Contracts and Futures Contracts
	The Company utilizes foreign currency option contracts to mitigate foreign currency risk. The Company uses exchange traded treasury note futures contracts to manage portfolio duration and equity futures to hedge certain investments.
	Credit Default Swaps
	The Company purchases protection through credit default swaps to mitigate the risk associated with its underwriting operations, most notably in the credit/surety line, and to manage market exposures.
	The Company also assumes credit risk through credit default swaps to replicate investment positions. The original term of these credit default swaps is generally five years or less and there are no recourse provisions associated with these swaps. While the Company would be required to perform under exposure assumed through credit default swaps in the event of a default on the underlying issuer. The counterparties on the Company's assumed credit default swaps are all investment grade rated financial institutions.
	Insurance-Linked Securities
	The Company enters into various weather derivatives and longevity total return swaps for which the underlying risks reference parametric weather risks for the weather derivatives and longevity risk for the longevity total return swaps.
	Total Return and Interest Rate Swaps and Interest Rate Derivatives
	The Company enters into total return swaps referencing various project, investments and principal finance obligations. The Company enters into interest rate swaps to mitigate the interest rate risk on certain of the total return swaps and certain fixed maturity investments. The Company also uses other interest rate derivatives to mitigate exposure to interest rate volatility.
	To-Be-Announced Mortgage-Backed Securities
	The Company utilizes TBAs as part of its overall investment strategy and to enhance investment performance.
	The net fair values and the related net notional values of derivatives included in the Company's Condensed Consolidated Balance Sheets at March 31, 2014 and December 31, 2013 were as follows (in thousands of U.S. dollars):

	In March 2013, the Company formed with other third party investors, Lorenz Re Ltd. (Lorenz Re), a Bermuda domiciled special purpose insurer to provide additional capacity to the Company for a diversified portfolio of catastrophe reinsurance treaties over a multi-year period on a fully collateralized reinsurance basis. The original business was written by the Company and was ceded to Lorenz Re effective April 1, 2013.
	Lorenz Re's non-voting redeemable preferred share capital is redeemable at the option of the Company and is expected to be redeemed following the commutation of the portfolio back to the Company on or before June 1, 2016.
	At March 31, 2014 and December 31, 2013, the total assets of Lorenz Re were $99.1 million and $99.6 million, respectively, primarily consisting of cash and investments. At March 31, 2014 and December 31, 2013, the total liabilities were $5.8 million and $11.1 million, respectively, primarily consisting of unpaid losses and loss expenses and other reinsurance balances payable for 2014 and unearned premiums and unpaid losses and loss expenses for 2013. The assets of Lorenz Re can only be used to settle the liabilities of Lorenz Re and there is no recourse to the Company for any liabilities of Lorenz Re.

	Financing receivables
	Included in the Company's Other invested assets are certain notes receivable which meet the definition of financing receivables and are accounted for using the cost method of accounting. These notes receivable are collateralized by commercial or residential property. The Company utilizes a third party consultant to determine the initial investment criteria and to monitor the subsequent performance of the notes receivable. The process undertaken prior to the investment in these notes receivable includes an examination of the underlying collateral. The Company reviews its receivable positions on at least a quarterly basis using actual redemption experience. At March 31, 2014 and December 31, 2013, based on the latest available information, the Company recorded an allowance for credit losses related to these notes receivable of $2.4 million and $2.8 million, respectively.
	The Company monitors the performance of the notes receivable based on the type of underlying collateral and by assigning a “performing” or a “non-performing” indicator of credit quality to each individual receivable. At March 31, 2014, the Company's notes receivable of $19.3 million were all performing and were collateralized by residential property and commercial property of $15.7 million and $3.6 million, respectively. At December 31, 2013, the Company's notes receivable of $24.5 million were all performing and were collateralized by residential property and commercial property of $19.8 million and $4.7 million, respectively.
	There were no significant purchases or sales of financing receivables during the three months ended March 31, 2014 and 2013, however, the outstanding balances were reduced by settlements of the underlying debt.
	(b) Legal Proceedings
	There has been no significant change in legal proceedings at March 31, 2014 compared to December 31, 2013. See Note 18(f) to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	(c) Other
	At March 31, 2014, there were no restrictions on the Company's ability to pay common and preferred shareholders' dividends from retained earnings. The declaration of dividends by PartnerRe Bermuda is subject to prior regulatory approval through December 31, 2014.

	9. Segment Information
	The Company monitors the performance of its operations in three segments, Non-life, Life and Health and Corporate and Other as described in Note 21 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. The Non-life segment is further divided into four sub-segments: North America, Global (Non-U.S.) P&C, Global Specialty and Catastrophe.
	The North America sub-segment includes agriculture, casualty, credit/surety, motor, multiline, property and other risks generally originating in the United States. The Global (Non-U.S.) P&C sub-segment includes casualty, motor and property business generally originating outside of the United States. The Global Specialty sub-segment is comprised of business that is generally considered to be specialized due to the sophisticated technical underwriting required to analyze risks, and is global in nature. This sub-segment consists of several lines of business for which the Company believes it has developed specialized knowledge and underwriting capabilities. These lines of business include agriculture, aviation/space, credit/surety, energy, engineering, marine, specialty casualty, specialty property and other lines. The Catastrophe sub-segment is comprised of the Company's catastrophe line of business. The Life and Health segment includes mortality, longevity and accident and health lines of business. Corporate and Other is comprised of the capital markets and investment related activities of the Company, including principal finance transactions, insurance-linked securities and strategic investments, and its corporate activities, including other operating expenses.
	Since the Company does not manage its assets by segment, net investment income is not allocated to the Non-life segment. However, because of the interest-sensitive nature of some of the Company's Life and Health products, net investment income is considered in Management's assessment of the profitability of the Life and Health segment. The following items are not considered in evaluating the results of the Non-life and Life and Health segments: net realized and unrealized investment gains and losses, interest expense, amortization of intangible assets, net foreign exchange gains and losses, income tax expense or benefit and interest in earnings and losses of equity method investments. Segment results are shown before consideration of intercompany transactions.
	Management measures results for the Non-life segment on the basis of the loss ratio, acquisition ratio, technical ratio, other operating expense ratio and combined ratio (all defined below). Management measures results for the Non-life sub-segments on the basis of the loss ratio, acquisition ratio and technical ratio. Management measures results for the Life and Health segment on the basis of the allocated underwriting result, which includes revenues from net premiums earned, other income or loss and allocated net investment income for Life and Health, and expenses from life policy benefits, acquisition costs and other operating expenses.
	The following tables provide a summary of the segment results for the three months ended March 31, 2014 and 2013 (in millions of U.S. dollars, except ratios):

Disclosure - Significant Accounting Policies [Abstract]	'
Basis of accounting	'
Basis of accounting	The Company's Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. The Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions have been eliminated.
Use Of Estimates	'
	The preparation of financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While Management believes that the amounts included in the Condensed Consolidated Financial Statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company's principal estimates include:
	• Unpaid losses and loss expenses;
	• Policy benefits for life and annuity contracts;
	• Gross and net premiums written and net premiums earned;
	• Recoverability of deferred acquisition costs;
	• Recoverability of deferred tax assets;
	• Valuation of goodwill and intangible assets; and
	• Valuation of certain assets and derivative financial instruments that are measured using significant unobservable inputs.
Recent Accounting Pronouncements	'

	3. Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board issued updated guidance on the accounting for investments in affordable housing projects that qualify for low-income housing tax credits by entities that manage or invest in such projects. The update modifies the conditions that an entity must meet to elect the effective yield or proportional amortization method to account for such investments. The guidance is effective for interim and annual periods beginning after December 15, 2014, with early adoption permitted. The Company does not expect the adoption of this guidance to have a significant impact on its Consolidated Financial Statements or disclosures.

	(1) At March 31, 2014 and December 31, 2013, insurance-linked securities include a longevity swap for which the notional amount is not reflective of the overall potential exposure of the swap. As such, the Company has included the probable maximum loss under the swap within the net notional exposure as an approximation of the notional amount.
	(2) The Company enters into interest rate swaps to mitigate notional exposures on certain total return swaps and certain fixed maturities. Only the notional value of interest rate swaps on fixed maturities is presented separately in the table.

[1]	Amounts include all derivative instruments, irrespective of whether there is a legally enforceable master netting arrangement in place.
[2]	At March 31, 2014 and December 31, 2013, insurance-linked securities include a longevity swap for which the notional amount is not reflective of the overall potential exposure of the swap. As such, the Company has included the probable maximum loss under the swap within the net notional exposure as an approximation of the notional amount.
[3]	The Company enters into interest rate swaps to mitigate notional exposures on certain total return swaps and certain fixed maturities. Only the notional value of interest rate swaps on fixed maturities is presented separately in the table.
