	Global Indemnity plc (“Global Indemnity” or “the Company”) was incorporated on March 9, 2010 and is domiciled in Ireland. Global Indemnity replaced the Company’s predecessor, United America Indemnity, Ltd., as the ultimate parent company as a result of a re-domestication transaction. United America Indemnity, Ltd. was incorporated on August 26, 2003, and is domiciled in the Cayman Islands. United America Indemnity, Ltd. is now a subsidiary of the Company. The Company’s A ordinary shares are publicly traded on the NASDAQ Global Select Market under the trading symbol “GBLI.”
	The Company manages its business through two business segments: Insurance Operations, which includes the operations of United National Insurance Company, Diamond State Insurance Company, United National Specialty Insurance Company, Penn-America Insurance Company, Penn-Star Insurance Company, Penn-Patriot Insurance Company, American Insurance Adjustment Agency, Inc., Collectibles Insurance Services, LLC, Global Indemnity Insurance Agency, LLC, and J.H. Ferguson & Associates, LLC, and Reinsurance Operations, which includes the operations of Wind River Reinsurance Company, Ltd. (“Wind River Reinsurance”).
	The interim consolidated financial statements are unaudited, but have been prepared in conformity with United States of America generally accepted accounting principles (“GAAP”), which differs in certain respects from those principles followed in reports to insurance regulatory authorities. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The unaudited consolidated financial statements include all adjustments that are, in the opinion of management, of a normal recurring nature and are necessary for a fair statement of results for the interim periods. Results of operations for the quarters ended March 31, 2014 and 2013 are not necessarily indicative of the results of a full year. The accompanying notes to the unaudited consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements contained in the Company’s 2013 Annual Report on Form 10-K.
	The consolidated financial statements include the accounts of Global Indemnity and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

-2	Fixed maturities in a gross unrealized loss position for twelve months or longer are primarily comprised of non-credit losses on investment grade securities where management does not intend to sell, and it is more likely than not that the Company will not be forced to sell the security before recovery. The Company has analyzed these securities and has determined that they are not other than temporarily impaired.
The Company regularly performs various analytical valuation procedures with respect to its investments, including reviewing each fixed maturity security in an unrealized loss position to assess whether the security is a candidate for credit loss. Specifically, the Company considers credit rating, market price, and issuer specific financial information, among other factors, to assess the likelihood of collection of all principal and interest as contractually due. Securities for which the Company determines that a credit loss is likely are subjected to further analysis through discounted cash flow testing to estimate the credit loss to be recognized in earnings, if any. The specific methodologies and significant assumptions used by asset class are discussed below. Upon identification of such securities and periodically thereafter, a detailed review is performed to determine whether the decline is considered other than temporary. This review includes an analysis of several factors, including but not limited to, the credit ratings and cash flows of the securities and the magnitude and length of time that the fair value of such securities is below cost.
For fixed maturities, the factors considered in reaching the conclusion that a decline below cost is other than temporary include, among others, whether:
	-1	the issuer is in financial distress;
	-2	the investment is secured;
	-3	a significant credit rating action occurred;
	-4	scheduled interest payments were delayed or missed;
	-5	changes in laws or regulations have affected an issuer or industry;
	-6	the investment has an unrealized loss and was identified by the Company’s investment manager as an investment to be sold before recovery or maturity; and
	-7	the investment failed cash flow projection testing to determine if anticipated principal and interest payments will be realized.
According to accounting guidance for debt securities in an unrealized loss position, the Company is required to assess whether it has the intent to sell the debt security or more likely than not will be required to sell the debt security before the anticipated recovery. If either of these conditions is met the Company must recognize an other than temporary impairment with the entire unrealized loss being recorded through earnings. For debt securities in an unrealized loss position not meeting these conditions, the Company assesses whether the impairment of a security is other than temporary. If the impairment is deemed to be other than temporary, the Company must separate the other than temporary impairment into two components: the amount representing the credit loss and the amount related to all other factors, such as changes in interest rates. The credit loss represents the portion of the amortized book value in excess of the net present value of the projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. The credit loss component of the other than temporary impairment is recorded through earnings, whereas the amount relating to factors other than credit losses is recorded in other comprehensive income, net of taxes.
For equity securities, management carefully reviews all securities with unrealized losses to determine if a security should be impaired and further focuses on securities that have either:
	-1	persisted with unrealized losses for more than twelve consecutive months or
	-2	the value of the investment has been 20% or more below cost for six continuous months or more.
The amount of any write-down, including those that are deemed to be other than temporary, is included in earnings as a realized loss in the period in which the impairment arose.
The following is a description, by asset type, of the methodology and significant inputs that the Company used to measure the amount of credit loss recognized in earnings, if any:
U.S. treasury and agency obligations - As of March 31, 2014, gross unrealized losses related to U.S. treasury and agency obligations were $0.139 million. All unrealized losses have been in an unrealized loss position for less than twelve months. All of these securities are rated AA+. Extensive macroeconomic and market analysis is conducted in evaluating these securities. The analysis is driven by moderate interest rate anticipation, yield curve management, and security selection.
Obligations of states and political subdivisions - As of March 31, 2014, gross unrealized losses related to obligations of states and political subdivisions were $1.146 million. Of this amount, $0.294 million have been in an unrealized loss position for twelve months or greater and are rated A- or better. All factors that influence performance of the municipal bond market are considered in evaluating these securities. The aforementioned factors include investor expectations, supply and demand patterns, and current versus historical yield and spread relationships. The analysis relies on the output of fixed income credit analysts, as well as dedicated municipal bond analysts who perform extensive in-house fundamental analysis on each issuer, regardless of their rating by the major agencies.
Mortgage-backed securities (“MBS”) - As of March 31, 2014, gross unrealized losses related to mortgage-backed securities were $2.123 million. Of this amount, $0.136 million have been in an unrealized loss position for twelve months or greater and are rated AA+. Mortgage-backed securities are modeled to project principal losses under downside, base, and upside scenarios for the economy and home prices. The primary assumption that drives the security and loan level modeling is the Home Price Index (“HPI”) projection. The model first projects HPI at the national level, then at the zip-code level based on the historical relationship between the individual zip code HPI and the national HPI. The model utilizes loan level data and borrower characteristics including FICO score, geographic location, original and current loan size, loan age, mortgage rate and type (fixed rate / interest-only / adjustable rate mortgage), issuer / originator, residential type (owner occupied / investor property), dwelling type (single family / multi-family), loan purpose, level of documentation, and delinquency status as inputs. The model also includes the explicit treatment of silent second liens, utilization of loan modification history, and the application of roll rate adjustments.
Asset-backed securities (“ABS”) - As of March 31, 2014, gross unrealized losses related to asset backed securities were $0.168 million. Of this amount, $0.001 million have been in an unrealized loss position for twelve months or greater and are rated A or better. The weighted average credit enhancement for the Company’s asset backed portfolio is 23.9. This represents the percentage of pool losses that can occur before an asset backed security will incur its first dollar of principal losses. Every ABS transaction is analyzed on a stand-alone basis. This analysis involves a thorough review of the collateral, prepayment, and structural risk in each transaction. Additionally, the analysis includes an in-depth credit analysis of the originator and servicer of the collateral. The analysis projects an expected loss for a deal given a set of assumptions specific to the asset type. These assumptions are used to calculate at what level of losses the deal will incur its first dollar of principal loss. The major assumptions used to calculate this ratio are loss severities, recovery lags, and no advances on principal and interest.
Commercial mortgage-backed securities (“CMBS”) - As of March 31, 2014, gross unrealized losses related to the CMBS portfolio were $0.402 million. All unrealized losses have been in an unrealized loss position for less than twelve months. All of these securities are rated AA or better. The weighted average credit enhancement for the Company’s CMBS portfolio is 31.1. This represents the percentage of pool losses that can occur before a mortgage-backed security will incur its first dollar of principal loss. For the Company’s CMBS portfolio, a loan level analysis is utilized where every underlying CMBS loan is re-underwritten based on a set of assumptions reflecting expectations for the future path of the economy. In the analysis, the focus is centered on stressing the significant variables that influence commercial loan defaults and collateral losses in CMBS deals. These variables include: (1) a projected drop in occupancies; (2) capitalization rates that vary by property type and are forecasted to return to more normalized levels as the capital markets repair and capital begins to flow again; and (3) property value stress testing using projected property performance and projected capitalization rates. Term risk is triggered if the projected debt service coverage rate falls below 1x. Balloon risk is triggered if a property’s projected performance does not satisfy new tighter mortgage standards.
Corporate bonds and loans - As of March 31, 2014, gross unrealized losses related to corporate bonds and loans were $0.450 million. All unrealized losses have been in an unrealized loss position for less than twelve months. These securities are rated investment grade. The analysis for this sector includes maintaining detailed financial models that include a projection of each issuer’s future financial performance, including prospective debt servicing capabilities, capital structure composition, and the value of the collateral. The analysis incorporates the macroeconomic environment, industry conditions in which the issuer operates, the issuer’s current competitive position, its vulnerability to changes in the competitive and regulatory environment, issuer liquidity, issuer commitment to bondholders, issuer creditworthiness, and asset protection. Part of the process also includes running downside scenarios to evaluate the expected likelihood of default as well as potential losses in the event of default.
Foreign bonds - As of March 31, 2014, gross unrealized losses related to foreign bonds were $0.070 million. All unrealized losses have been in an unrealized loss position for less than twelve months. These securities are rated investment grade. For this sector, detailed financial models are maintained that include a projection of each issuer’s future financial performance, including prospective debt servicing capabilities, capital structure composition, and the value of the collateral. The analysis incorporates the macroeconomic environment, industry conditions in which the issuer operates, the issuer’s current competitive position, its vulnerability to changes in the competitive and regulatory environment, issuer liquidity, issuer commitment to bondholders, issuer creditworthiness, and asset protection. Part of the process also includes running downside scenarios to evaluate the expected likelihood of default as well as potential losses in the event of default.
Common stock - As of March 31, 2014, gross unrealized losses related to common stock were $1.248 million. Of this amount, $0.015 million have been in an unrealized loss position for twelve months or greater. To determine if an other than temporary impairment of an equity security has occurred, the Company considers, among other things, the severity and duration of the decline in fair value of the equity security. The Company also examines other factors to determine if the equity security could recover its value in a reasonable period of time.
Other invested assets - As of March 31, 2014, gross unrealized losses related to other invested assets were $0.085 million. All securities have been in an unrealized loss position for less than twelve months.

Insurance Enhanced Municipal Bonds
As of March 31, 2014, the Company held insurance enhanced municipal bonds of approximately $26.5 million, which represented approximately 1.7% of the Company’s total cash and invested assets, net of payable/receivable for securities purchased and sold. These securities had an average rating of “AA-.” Approximately $2.9 million of these bonds are pre-refunded with U.S. treasury securities, of which $1.2 million are backed by financial guarantors, meaning that funds have been set aside in escrow to satisfy the future interest and principal obligations of the bond. Of the remaining $23.6 million of insurance enhanced municipal bonds, $15.0 million would have carried a lower credit rating had they not been insured. The following table provides a breakdown of the ratings for these municipal bonds with and without insurance.

Derivative Instruments

Interest rate swaps are used by the Company primarily to reduce risks from changes in interest rates. Under the terms of the interest rate swaps, the Company agrees with another party to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts as calculated by reference to an agreed notional amount. As of March 31, 2014, the Company posted collateral of $4.9 million which is included in other assets on the consolidated balance sheets.

The Company accounts for its interest rate swaps in accordance with accounting guidance under Financial Accounting Standards Codification (“ASC”) section 815, Derivatives and Hedging. The Company has designated the interest rate swaps as non-hedge instruments. Accordingly, the Company recognizes the fair value of the interest rate swaps in other assets or other liabilities on the consolidated balance sheets with the changes in fair value recognized as net realized investment gains in the consolidated statement of operations. The estimated fair value of the interest rate swaps, which is primarily derived from the forward interest rate curve, is based on the valuation received from a third party financial institution.

The following table summarizes information on the location and amount of the derivatives’ fair value on the consolidated balance sheets as of March 31, 2014 and December 31, 2013:

Fair Value Measurements	'
	4	Fair Value Measurements
	The accounting standards related to fair value measurements define fair value, establish a framework for measuring fair value, outline a fair value hierarchy based on inputs used to measure fair value, and enhance disclosure requirements for fair value measurements. These standards do not change existing guidance as to whether or not an instrument is carried at fair value. The Company has determined that its fair value measurements are in accordance with the requirements of these accounting standards.
	The Company’s invested assets are carried at their fair value and are categorized based upon a fair value hierarchy:
		•		Level 1 - inputs utilize quoted prices (unadjusted) in active markets for identical assets that the Company has the ability to access at the measurement date.
		•		Level 2 - inputs utilize other than quoted prices included in Level 1 that are observable for similar assets, either directly or indirectly.
		•		Level 3 - inputs are unobservable for the asset, and include situations where there is little, if any, market activity for the asset.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. 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 asset.
	Both observable and unobservable inputs may be used to determine the fair value of positions that the Company has classified within the Level 3 category. As a result, the unrealized gains and losses for invested assets within the Level 3 category presented in the tables below may include changes in fair value that are attributed to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.
	The following table presents information about the Company’s invested assets measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value.

	The securities classified as Level 1 in the above table consist of U.S. Treasuries and equity securities actively traded on an exchange.
	The securities classified as Level 2 in the above table consist primarily of fixed maturity securities and derivative instruments. Based on the typical trading volumes and the lack of quoted market prices for fixed maturities, security prices are derived through recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. If there are no recent reported trades, matrix or model processes are used to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Included in the pricing of asset-backed securities, collateralized mortgage obligations, and mortgage-backed securities are estimates of the rate of future prepayments of principal over the remaining life of the securities. Such estimates are derived based on the characteristics of the underlying structure and prepayment speeds previously experienced at the interest rate levels projected for the underlying collateral. For corporate loans, price quotes from multiple dealers along with recent reported trades for identical or similar securities are used to develop prices. The estimated fair value of the interest rate swaps is obtained from a third party financial institution who utilizes observable inputs such as the forward interest rate curve.
	There were no transfers between Level 1 and Level 2 during the quarters ended March 31, 2014 or 2013.
	The following table presents changes in Level 3 investments measured at fair value on a recurring basis for the quarters ended March 31, 2014 and 2013:

	The investments classified as Level 3 in the above table relate to investments in limited partnerships. The Company does not have access to daily valuations; therefore, the estimated fair values of the limited partnerships are measured utilizing net asset value as a practical expedient for the limited partnerships.

Pricing
The Company’s pricing vendors provide prices for all investment categories except for investments in limited partnerships which are measured utilizing net asset values as a practical expedient. One vendor provides prices for equity securities and all fixed maturity categories.
The following is a description of the valuation methodologies used by the Company’s pricing vendors for investment securities carried at fair value:
	•		Equity prices are received from all primary and secondary exchanges.
	•		Corporate and agency bonds are evaluated by utilizing a multi-dimensional relational model. For bonds with early redemption options, an option adjusted spread model is utilized. Both asset classes use standard inputs and incorporate security set up, defined sector breakdown, benchmark yields, apply base spreads, yield to maturity, and adjust for corporate actions.
	•		A volatility-driven multi-dimensional spread table or an option-adjusted spread model and prepayment model is used for agency commercial mortgage obligations (“CMO”). For non-agency CMOs, a prepayment/spread/yield/price adjustment model is utilized. CMOs are categorized with mortgage-backed securities in the tables listed above. For ABSs, a multi-dimensional, collateral specific spread / prepayment speed tables is utilized. For both asset classes, evaluations utilize standard inputs plus new issue data, monthly payment information, and collateral performance. The evaluated pricing models incorporate security set-up, prepayment speeds, cash flows, and treasury swap curves and spread adjustments.
	•		For municipals, a multi-dimensional relational model is used to evaluate securities within this asset class. The evaluated pricing models for this asset class incorporate security set-up, benchmark yields, apply base spreads, yield to worst or market convention, ratings updates, prepayment schedules and adjustments for material events notices.
	•		U.S. treasuries are evaluated by obtaining feeds from a number of live data sources including active market makers and inter-dealer brokers.
	•		For MBSs, a matrix model correlation to TBA (a forward MBS trade) or benchmarking is utilized to value a security.
The Company performs certain procedures to validate whether the pricing information received from the pricing vendors is reasonable, to ensure that the fair value determination is consistent with accounting guidance, and to ensure that its assets are properly classified in the fair value hierarchy. The Company’s procedures include, but are not limited to:
	•		Reviewing periodic reports provided by the Investment Manager that provide information regarding rating changes and securities placed on watch. This procedure allows the Company to understand why a particular security’s market value may have changed.
	•		Understanding and periodically evaluating the various pricing methods and procedures used by the Company’s pricing vendors to ensure that investments are properly classified within the fair value hierarchy.
	•		On a quarterly basis, the Company corroborates investment security prices received from its pricing vendors by obtaining pricing from a second pricing vendor for a sample of securities.
During the quarters ended March 31, 2014 and 2013, the Company has not adjusted quotes or prices obtained from the pricing vendors.

Income Taxes	'
	5	Income Taxes
	The statutory income tax rates of the countries where the Company does business are 35.0% in the United States, 0.0% in Bermuda, 0.0% in the Cayman Islands, 0.0% in Gibraltar, 29.22% in the Duchy of Luxembourg, and 25.0% on non-trading income, 33.0% on capital gains and 12.5% on trading income in the Republic of Ireland. The statutory income tax rate of each country is applied against the expected annual taxable income of the Company in each country to estimate the annual income tax expense. Total estimated annual income tax expense is divided by total estimated annual pre-tax income to determine the expected annual income tax rate used to compute the income tax provision. On an interim basis, the expected annual income tax rate is applied against interim pre-tax income, excluding net realized gains and losses and discrete items such as limited partnership distributions, and then that amount is added to income taxes on net realized gains and losses and discrete items.
	The Company’s income before income taxes from its non-U.S. subsidiaries and U.S. subsidiaries, including the results of the quota share and stop-loss agreements between Wind River Reinsurance and the Insurance Operations, for the quarters ended March 31, 2014 and 2013 were as follows:

	The effective income tax benefit rate for the quarter ended March 31, 2014 was 26.5%, compared to an effective income tax benefit rate of 2.6% for the quarter ended March 31, 2013. The increase in the effective tax benefit rate is primarily due to the capital loss on the Company’s derivative instrument in 2014. Any difference between the actual tax rate on an interim basis compared to the expected annual tax rate is reflected in the effective tax rate adjustment. The effective income tax benefit rate of 26.5% and 2.6% for the quarters ended March 31, 2014 and 2013, respectively, differed from the weighted average expected income tax benefit rate of 23.8% and weighted average income tax expense rate of 2.9% for the quarters ended March 31, 2014 and 2013, respectively, due to the fact that the Company records income tax expense on an interim basis using the projected annual effective tax rate, net of tax-exempt interest and dividends.
	The Company had an alternative minimum tax credit carry forward of $9.9 million as of March 31, 2014 and December 31, 2013 which can be carried forward indefinitely. The company has a net operating loss (“NOL”) carryforward of $1.2 million as of March 31, 2014 and December 31, 2013 that expires in 2032.

	When analyzing loss reserves and prior year development, the Company considers many factors, including the frequency and severity of claims, loss trends, case reserve settlements that may have resulted in significant development, and any other additional or pertinent factors that may impact reserve estimates.
	In the first quarter of 2014, the Company reduced its prior accident year loss reserves by $2.1 million, which consisted of a $2.0 million decrease related to Insurance Operations and a $0.1 million decrease related to Reinsurance Operations.
	The $2.0 million decrease related to Insurance Operations primarily consisted of the following:
		•		General Liability: A $0.9 million decrease primarily driven by better than expected experience in the active general liability lines in accident years 2005 to 2011 offset by strengthening of environmental losses.
		•		Professional Liability: A $1.8 million decrease primarily driven by better than expected experience in the runoff of the professional liability lines in accident years 2005 to 2011.
		•		Other lines: increased $0.7 million mainly in the 2011 accident year due to higher than expected emergence for discontinued lines. As a result, management increased loss reserves.
	The $0.1 million decrease related to Reinsurance Operations is primarily related to a reduction in accident years 2010 to 2013 for property treaties.
	In the first quarter of 2013, the Company reduced its prior accident year loss reserves by $2.7 million, which consisted of a $2.8 million decrease related to Insurance Operations and a $0.1 million increase related to Reinsurance Operations.
	The $2.8 million decrease related to Insurance Operations consisted of a reduction in property lines primarily driven by better than expected emergence for accident years 2008 through 2012. The $0.1 million increase related to Reinsurance Operations primarily consisted of worse than expected emergence on a marine treaty.

	The Company is, from time to time, involved in various legal proceedings in the ordinary course of business. The Company maintains insurance and reinsurance coverage for such risks in amounts that it considers adequate. However, there can be no assurance that the insurance and reinsurance coverage that the Company maintains is sufficient or will be available in adequate amounts or at a reasonable cost. The Company does not believe that the resolution of any currently pending legal proceedings, either individually or taken as a whole, will have a material adverse effect on its business, results of operations, cash flows, or financial condition.
	There is a greater potential for disputes with reinsurers who are in runoff. Some of the Company’s reinsurers’ have operations that are in runoff, and therefore, the Company closely monitors those relationships.

Principles of Consolidation and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2014
Business Segments	'
	The Company manages its business through two business segments: Insurance Operations, which includes the operations of United National Insurance Company, Diamond State Insurance Company, United National Specialty Insurance Company, Penn-America Insurance Company, Penn-Star Insurance Company, Penn-Patriot Insurance Company, American Insurance Adjustment Agency, Inc., Collectibles Insurance Services, LLC, Global Indemnity Insurance Agency, LLC, and J.H. Ferguson & Associates, LLC, and Reinsurance Operations, which includes the operations of Wind River Reinsurance Company, Ltd. (“Wind River Reinsurance”).
Interim Consolidated Financial statements	'
	The interim consolidated financial statements are unaudited, but have been prepared in conformity with United States of America generally accepted accounting principles (“GAAP”), which differs in certain respects from those principles followed in reports to insurance regulatory authorities. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The unaudited consolidated financial statements include all adjustments that are, in the opinion of management, of a normal recurring nature and are necessary for a fair statement of results for the interim periods. Results of operations for the quarters ended March 31, 2014 and 2013 are not necessarily indicative of the results of a full year. The accompanying notes to the unaudited consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements contained in the Company’s 2013 Annual Report on Form 10-K.
Intercompany Balances and Transactions	'
	The consolidated financial statements include the accounts of Global Indemnity and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Investments	'
	The Company regularly performs various analytical valuation procedures with respect to its investments, including reviewing each fixed maturity security in an unrealized loss position to assess whether the security is a candidate for credit loss. Specifically, the Company considers credit rating, market price, and issuer specific financial information, among other factors, to assess the likelihood of collection of all principal and interest as contractually due. Securities for which the Company determines that a credit loss is likely are subjected to further analysis through discounted cash flow testing to estimate the credit loss to be recognized in earnings, if any. The specific methodologies and significant assumptions used by asset class are discussed below. Upon identification of such securities and periodically thereafter, a detailed review is performed to determine whether the decline is considered other than temporary. This review includes an analysis of several factors, including but not limited to, the credit ratings and cash flows of the securities and the magnitude and length of time that the fair value of such securities is below cost.
	For fixed maturities, the factors considered in reaching the conclusion that a decline below cost is other than temporary include, among others, whether:
		-1	the issuer is in financial distress;
		-2	the investment is secured;
		-3	a significant credit rating action occurred;
		-4	scheduled interest payments were delayed or missed;
		-5	changes in laws or regulations have affected an issuer or industry;
		-6	the investment has an unrealized loss and was identified by the Company’s investment manager as an investment to be sold before recovery or maturity; and
		-7	the investment failed cash flow projection testing to determine if anticipated principal and interest payments will be realized.
	According to accounting guidance for debt securities in an unrealized loss position, the Company is required to assess whether it has the intent to sell the debt security or more likely than not will be required to sell the debt security before the anticipated recovery. If either of these conditions is met the Company must recognize an other than temporary impairment with the entire unrealized loss being recorded through earnings. For debt securities in an unrealized loss position not meeting these conditions, the Company assesses whether the impairment of a security is other than temporary. If the impairment is deemed to be other than temporary, the Company must separate the other than temporary impairment into two components: the amount representing the credit loss and the amount related to all other factors, such as changes in interest rates. The credit loss represents the portion of the amortized book value in excess of the net present value of the projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. The credit loss component of the other than temporary impairment is recorded through earnings, whereas the amount relating to factors other than credit losses is recorded in other comprehensive income, net of taxes.
	For equity securities, management carefully reviews all securities with unrealized losses to determine if a security should be impaired and further focuses on securities that have either:
		-1	persisted with unrealized losses for more than twelve consecutive months or
		-2	the value of the investment has been 20% or more below cost for six continuous months or more.
Derivatives Policy	'
	The Company accounts for its interest rate swaps in accordance with accounting guidance under Financial Accounting Standards Codification (“ASC”) section 815, Derivatives and Hedging. The Company has designated the interest rate swaps as non-hedge instruments. Accordingly, the Company recognizes the fair value of the interest rate swaps in other assets or other liabilities on the consolidated balance sheets with the changes in fair value recognized as net realized investment gains in the consolidated statement of operations. The estimated fair value of the interest rate swaps, which is primarily derived from the forward interest rate curve, is based on the valuation received from a third party financial institution.
Fair Value Measurement Policy	'
	The accounting standards related to fair value measurements define fair value, establish a framework for measuring fair value, outline a fair value hierarchy based on inputs used to measure fair value, and enhance disclosure requirements for fair value measurements. These standards do not change existing guidance as to whether or not an instrument is carried at fair value. The Company has determined that its fair value measurements are in accordance with the requirements of these accounting standards.
	The Company’s invested assets are carried at their fair value and are categorized based upon a fair value hierarchy:
		•		Level 1 - inputs utilize quoted prices (unadjusted) in active markets for identical assets that the Company has the ability to access at the measurement date.
		•		Level 2 - inputs utilize other than quoted prices included in Level 1 that are observable for similar assets, either directly or indirectly.
		•		Level 3 - inputs are unobservable for the asset, and include situations where there is little, if any, market activity for the asset.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. 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 asset.
	Both observable and unobservable inputs may be used to determine the fair value of positions that the Company has classified within the Level 3 category. As a result, the unrealized gains and losses for invested assets within the Level 3 category presented in the tables below may include changes in fair value that are attributed to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.
	Based on the typical trading volumes and the lack of quoted market prices for fixed maturities, security prices are derived through recent reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. If there are no recent reported trades, matrix or model processes are used to develop a security price where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Included in the pricing of asset-backed securities, collateralized mortgage obligations, and mortgage-backed securities are estimates of the rate of future prepayments of principal over the remaining life of the securities. Such estimates are derived based on the characteristics of the underlying structure and prepayment speeds previously experienced at the interest rate levels projected for the underlying collateral. For corporate loans, price quotes from multiple dealers along with recent reported trades for identical or similar securities are used to develop prices. The estimated fair value of the interest rate swaps is obtained from a third party financial institution who utilizes observable inputs such as the forward interest rate curve.
	The Company’s pricing vendors provide prices for all investment categories except for investments in limited partnerships which are measured utilizing net asset values as a practical expedient.
	The following is a description of the valuation methodologies used by the Company’s pricing vendors for investment securities carried at fair value:
		•		Equity prices are received from all primary and secondary exchanges.
		•		Corporate and agency bonds are evaluated by utilizing a multi-dimensional relational model. For bonds with early redemption options, an option adjusted spread model is utilized. Both asset classes use standard inputs and incorporate security set up, defined sector breakdown, benchmark yields, apply base spreads, yield to maturity, and adjust for corporate actions.
		•		A volatility-driven multi-dimensional spread table or an option-adjusted spread model and prepayment model is used for agency commercial mortgage obligations (“CMO”). For non-agency CMOs, a prepayment/spread/yield/price adjustment model is utilized. CMOs are categorized with mortgage-backed securities in the tables listed above. For ABSs, a multi-dimensional, collateral specific spread / prepayment speed tables is utilized. For both asset classes, evaluations utilize standard inputs plus new issue data, monthly payment information, and collateral performance. The evaluated pricing models incorporate security set-up, prepayment speeds, cash flows, and treasury swap curves and spread adjustments.
		•		For municipals, a multi-dimensional relational model is used to evaluate securities within this asset class. The evaluated pricing models for this asset class incorporate security set-up, benchmark yields, apply base spreads, yield to worst or market convention, ratings updates, prepayment schedules and adjustments for material events notices.
		•		U.S. treasuries are evaluated by obtaining feeds from a number of live data sources including active market makers and inter-dealer brokers.
		•		For MBSs, a matrix model correlation to TBA (a forward MBS trade) or benchmarking is utilized to value a security.
Statutory income tax rates	'
	The statutory income tax rate of each country is applied against the expected annual taxable income of the Company in each country to estimate the annual income tax expense.
Loss Reserves And Prior Year Development	'
	When analyzing loss reserves and prior year development, the Company considers many factors, including the frequency and severity of claims, loss trends, case reserve settlements that may have resulted in significant development, and any other additional or pertinent factors that may impact reserve estimates.
Earnings Per Share	'
	Earnings per share have been computed using the weighted average number of ordinary shares and ordinary share equivalents outstanding during the period.
