Principles of Consolidation and Basis of Presentation	1. Principles of Consolidation and Basis of Presentation Global Indemnity Limited (“Global Indemnity” or “the Company”), incorporated on February 9, 2016, is domiciled in the Cayman Islands. On November 7, 2016, Global Indemnity replaced Global Indemnity plc as the ultimate parent company as a result of a redomestication transaction. The Company’s A ordinary shares are publicly traded on the NASDAQ Global Select Market under the ticker symbol GBLI. Please see Note 2 of the notes to the consolidated financial statements in Item 8 Part II of the Company’s 2016 Annual Report on Form 10-K The Company manages its business through three business segments: Commercial Lines, Personal Lines, and Reinsurance Operations. The Company’s Commercial Lines offers specialty property and casualty insurance products in the excess and surplus lines marketplace. The Company manages its Commercial Lines by differentiating them into four product classifications: Penn-America, which markets property and general liability products to small commercial businesses through a select network of wholesale general agents with specific binding authority; United National, which markets insurance products for targeted insured segments, including specialty products, such as property, general liability, and professional lines through program administrators with specific binding authority; Diamond State, which markets property, casualty, and professional lines products, which are developed by the Company’s underwriting department by individuals with expertise in those lines of business, through wholesale brokers and also markets through program administrators having specific binding authority; and Vacant Express, which insures dwellings which are currently vacant, undergoing renovation, or are under construction and is distributed through aggregators, brokers, and retail agents. These product classifications comprise the Company’s Commercial Lines business segment and are not considered individual business segments because each product has similar economic characteristics, distribution, and coverage. The Company’s Personal Lines segment offers specialty personal lines and agricultural coverage through general and specialty agents with specific binding authority on an admitted basis. Collectively, the Company’s U.S. insurance subsidiaries are licensed in all 50 states and the District of Columbia. The Commercial Lines and Personal Lines segments comprise the Company’s U.S. Insurance Operations (‘Insurance Operations”). The Company’s Reinsurance Operations consist solely of the operations of its Bermuda-based wholly-owned subsidiary, Global Indemnity Reinsurance Company, Ltd. (“Global Indemnity Reinsurance”). Global Indemnity Reinsurance is a treaty reinsurer of specialty property and casualty insurance and reinsurance companies. The Company’s Reinsurance Operations segment provides reinsurance solutions through brokers and primary writers including insurance and reinsurance companies. During the 1 st re-evaluated 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 and nine months ended September 30, 2017 and 2016 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 2016 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.

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 Obligations of states and political subdivisions – in-house Mortgage-backed securities (“MBS”) – HPI-adjusted Asset-backed securities (“ABS”) - in-depth Commercial mortgage-backed securities (“CMBS”) - re-underwritten Corporate bonds - A- Foreign bonds Common stock The Company recorded the following other than temporary impairments (“OTTI”) on its investment portfolio for the quarters and nine months ended September 30, 2017 and 2016: Quarters Ended September 30, Nine Months Ended (Dollars in thousands) 2017 2016 2017 2016 Fixed maturities: OTTI losses, gross $ — $ (108 ) $ (31 ) $ (201 ) Portion of loss recognized in other comprehensive income (pre-tax) — — — — Net impairment losses on fixed maturities recognized in earnings — (108 ) (31 ) (201 ) Equity securities (1,020 ) (2,106 ) (1,677 ) (4,280 ) Total $ (1,020 ) $ (2,214 ) $ (1,708 ) $ (4,481 ) The following table is an analysis of the credit losses recognized in earnings on fixed maturities held by the Company for the quarters and nine months ended September 30, 2017 and 2016 for which a portion of the OTTI loss was recognized in other comprehensive income.

Variable Interest Entities A Variable Interest Entity (VIE) refers to an investment in which an investor holds a controlling interest that is not based on the majority of voting rights. Under the VIE model, the party that has the power to exercise significant management influence and maintain a controlling financial interest in the entity’s economics is said to be the primary beneficiary, and is required to consolidate the entity within their results. Other entities that participate in a VIE, for which their financial interests fluctuate with changes in the fair value of the investment entity’s net assets but do not have significant management influence and the ability to direct the VIE’s significant economic activities are said to have a variable interest in the VIE but do not consolidate the VIE in their financial results. The Company has variable interests in three VIE’s for which it is not the primary beneficiary. These investments are accounted for under the equity method of accounting as their ownership interest exceeds 3% of their respective investments. The fair value of one of the Company’s VIE’s, which invests in distressed securities and assets, was $29.8 million and $32.9 million as of September 30, 2017 and December 31, 2016, respectively. The Company’s maximum exposure to loss from this VIE, which factors in future funding commitments, was $44.0 million at September 30, 2017 and $48.6 million at December 31, 2016. The fair value of a second VIE that provides financing for middle market companies, was $26.8 million at September 30, 2017 and $33.2 million at December 31, 2016. The Company’s maximum exposure to loss from this VIE, which factors in future funding commitments, was $38.6 million at September 30, 2017 and $42.3 million at December 31, 2016. During the 2 nd

Fair Value Measurements

Fair Value Measurements	9 Months Ended

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 and derivative instruments 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. The following table presents information about the Company’s invested assets and derivative instruments measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. As of September 30, 2017 Fair Value Measurements (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets: Fixed maturities: U.S. treasury and agency obligations $ 117,766 $ — $ — $ 117,766 Obligations of states and political subdivisions — 117,243 — 117,243 Mortgage-backed securities — 146,888 — 146,888 Commercial mortgage-backed securities — 139,093 — 139,093 Asset-backed securities — 209,520 — 209,520 Corporate bonds — 488,593 — 488,593 Foreign corporate bonds — 141,060 — 141,060 Total fixed maturities 117,766 1,242,397 — 1,360,163 Common stock 133,462 — — 133,462 Total assets measured at fair value (1) $ 251,228 $ 1,242,397 $ — $ 1,493,625 Liabilities: Derivative instruments $ — $ 10,702 $ — $ 10,702 Total liabilities measured at fair value $ — $ 10,702 $ — $ 10,702 (1) Excluded from the table above are limited partnerships of $73.6 million at September 30, 2017 whose fair value is based on net asset value as a practical expedient.

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. The estimated fair value of the derivative instruments, consisting of interest rate swaps, is obtained from a third party financial institution that utilizes observable inputs such as the forward interest rate curve. For the Company’s material debt arrangements, the current fair value of the Company’s debt at September 30, 2017 and December 31, 2016 was as follows: September 30, 2017 December 31, 2016 (Dollars in thousands) Carrying Value Fair Value Carrying Value Fair Value Margin Borrowing Facility $ 76,518 $ 76,518 $ 66,646 $ 66,646 7.75% Subordinated Notes due 2045 (1) 96,588 100,448 96,497 95,697 7.875% Subordinated Notes due 2047 (2) 125,829 130,009 — — Total $ 298,935 $ 306,975 $ 163,143 $ 162,343 (1) As of September 30, 2017 and December 31, 2016, the carrying value and fair value of the 7.75% Subordinated Notes due 2045 are net of unamortized debt issuance cost of $3.4 million and $3.5 million, respectively. (2) As of September 30, 2017, the carrying value and fair value of the 7.875% Subordinated Notes due 2047 are net of unamortized debt issuance cost of $4.2 million. The fair value of the margin borrowing facility approximates its carrying value due to the facility being due on demand. The subordinated notes due 2045 and 2047 are publicly traded instruments and are classified as Level 1 in the fair value hierarchy. There were no transfers between Level 1 and Level 2 during the quarters ended September 30, 2017 and 2016. Fair Value of Alternative Investments Other invested assets consist of limited liability partnerships whose fair value is based on net asset value per share as a practical expedient. The following table provides the fair value and future funding commitments related to these investments at September 30, 2017 and December 31, 2016.

(2) This limited partnership invests in distressed securities and assets through senior and subordinated, secured and unsecured debt and equity, in both public and private large-cap (3) This limited partnership provides financing for middle market companies. The Company does not have the ability to sell or transfer its limited partnership interest without consent from the general partner. The Company does not have the contractual option to redeem its limited partnership interest but receives distributions based on the liquidation of the underlying assets. Based on the terms of the investment management agreement, the Company anticipates its interest to be redeemed no later than 2024. (4) This limited partnership invests in stressed and distressed debt instruments. The Company does not have the ability to sell or transfer its limited partnership interest without consent from the general partner. The Company does not have the contractual option to redeem its limited partnership interest but receives distributions based on the liquidation of the underlying assets. Based on the terms of the partnership agreement, the Company anticipates its interest to be redeemed no later than 2027. Limited Liability Companies and Limited Partnerships with ownership interest exceeding 3% The Company uses the equity method to account for investments in limited liability companies and limited partnerships where its ownership interest exceeds 3%. The equity method of accounting for an investment in a limited liability company and limited partnership requires that its cost basis be updated to account for the income or loss earned on the investment. The investment income or loss associated with these limited liability companies or limited partnerships, which is reflected in the consolidated statements of operations, was $0.7 million and $0.9 million during the quarters end September 30, 2017 and 2016, respectively, and $2.4 million and $3.7 million during the nine months ended September 30, 2017 and 2016, respectively. Pricing The Company’s pricing vendors provide prices for all investment categories except for investments in limited partnerships whose fair value is based on net asset values as a practical expedient. Two primary vendors are utilized to provide prices for equity and fixed maturity securities. The following is a description of the valuation methodologies used by the Company’s pricing vendors for investment securities carried at fair value: • Common stock 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. • Data from commercial vendors is aggregated with market information, then converted into a prepayment/spread/LIBOR curve model used for commercial mortgage obligations (“CMO”). CMOs are categorized with mortgage-backed securities in the tables listed above. For asset-backed securities, data derived from market information along with trustee and servicer reports is converted into spreads to interpolated swap yield curve. For both asset classes, evaluations utilize standard inputs plus new issue data, monthly payment information, and collateral performance. The evaluated pricing models incorporate discount rates, loan level information, prepayment speeds, treasury benchmarks, and LIBOR and swap curves. • For obligations of state and political subdivisions, a multi-dimensional relational model is used to evaluate securities. The pricing models incorporate security set-up, • U.S. treasuries are evaluated by obtaining feeds from a number of live data sources including active market makers and inter-dealer brokers. • For mortgage-backed securities, a matrix model correlation to 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 provides information regarding rating changes and securities placed on watch.

The increase in the income tax benefit rate is primarily due to losses incurred in the Company’s U.S. operations for the quarter ended September 30, 2017 as compared to a gain in 2016. Taxes were computed using a discrete period computation because a reliable estimate of an effective tax rate could not be made.

Commitments and Contingencies	10. Commitments and Contingencies Legal Proceedings The Company is, from time to time, involved in various legal proceedings in the ordinary course of business.

There is a greater potential for disputes with reinsurers who are in runoff.

A reconciliation of weighted average shares for basic earnings per share to weighted average shares for diluted earnings per share is as follows: Quarters Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Weighted average shares for basic earnings per share 17,343,292 17,254,843 17,331,840 17,241,040 Non-vested — 176,087 149,490 165,011 Options — 109,130 203,189 109,803 Weighted average shares for diluted earnings per share 17,343,292 17,540,060 17,684,519 17,515,854 If the Company had not incurred a loss in the quarter ended September 30, 2017, 17,721,954 weighted average shares would have been used to compute the diluted loss per share calculation which would have included 164,693 shares of non-vested The weighted average shares outstanding used to determine dilutive earnings per share for the quarter and nine months ended September 30, 2016 do not include 300,000 shares which were deemed to be anti-dilutive. There were no anti-dilutive shares for the quarter or nine months ended September 30, 2017.

New Accounting Pronouncements

New Accounting Pronouncements	14. New Accounting Pronouncements In May, 2017, the Financial Accounting Standards Board (“FASB”) issued updated accounting guidance which clarifies whether changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This guidance is effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. Although the Company is still evaluating the impact of this new guidance, the Company does not anticipate it will have a material impact on its financial condition, results of operations, or cash flows. In March, 2017, the FASB issued new accounting guidance which amends the amortization period for certain purchased callable debt securities held at a premium. Under current generally accepted accounting principles, entities generally amortize the premium as an adjustment of yield over the contractual life of the instruments. Under the new guidance, the amortizations period would be shortened to the earliest call date. This guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The Company is still evaluating the impact of this guidance on its financial condition, results of operations, and cash flows. In January, 2017, the FASB issued updated guidance that simplifies how an entity is required to test goodwill for impairment by eliminating the requirement to calculate the implied fair value of goodwill (i.e. Step 2 of the current goodwill impairment test). Under the new amendments, an entity may still first assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of a goodwill impairment loss to be recognized, if any. A goodwill impairment loss is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. This guidance is effective for public business entities’ annual or interim goodwill impairment testing in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Although the Company is still evaluating the impact of this new guidance, the Company does not anticipate it will have a material impact on its financial condition, results of operations, or cash flows. In January, 2017, the FASB amended The Accounting Standards Codification to incorporate SEC Staff Announcements at the September 22, 2016 and November 17, 2016 Emerging Issues Task Force (EITF) Meetings. The announcement from September 22, 2016 specifically addresses Accounting Standards Update (ASU) No. 2014-09, No. 2016-02, No. 2016-13, In February, 2016, the FASB issued ASU No. 2016-02, right-of-use In June, 2016, the FASB issued ASU 2016-13, In May, 2014, the FASB issued (ASU) No. 2014-09, Please see Note 22 of the notes to the consolidated financial statements in Item 8 Part II of the Company’s 2016 Annual Report on Form 10-K

Business Segments	The Company manages its business through three business segments: Commercial Lines, Personal Lines, and Reinsurance Operations. The Company’s Commercial Lines offers specialty property and casualty insurance products in the excess and surplus lines marketplace. The Company manages its Commercial Lines by differentiating them into four product classifications: Penn-America, which markets property and general liability products to small commercial businesses through a select network of wholesale general agents with specific binding authority; United National, which markets insurance products for targeted insured segments, including specialty products, such as property, general liability, and professional lines through program administrators with specific binding authority; Diamond State, which markets property, casualty, and professional lines products, which are developed by the Company’s underwriting department by individuals with expertise in those lines of business, through wholesale brokers and also markets through program administrators having specific binding authority; and Vacant Express, which insures dwellings which are currently vacant, undergoing renovation, or are under construction and is distributed through aggregators, brokers, and retail agents. These product classifications comprise the Company’s Commercial Lines business segment and are not considered individual business segments because each product has similar economic characteristics, distribution, and coverage. The Company’s Personal Lines segment offers specialty personal lines and agricultural coverage through general and specialty agents with specific binding authority on an admitted basis. Collectively, the Company’s U.S. insurance subsidiaries are licensed in all 50 states and the District of Columbia. The Commercial Lines and Personal Lines segments comprise the Company’s U.S. Insurance Operations (‘Insurance Operations”). The Company’s Reinsurance Operations consist solely of the operations of its Bermuda-based wholly-owned subsidiary, Global Indemnity Reinsurance Company, Ltd. (“Global Indemnity Reinsurance”). Global Indemnity Reinsurance is a treaty reinsurer of specialty property and casualty insurance and reinsurance companies. The Company’s Reinsurance Operations segment provides reinsurance solutions through brokers and primary writers including insurance and reinsurance companies. During the 1 st re-evaluated
Intercompany Balances and Transactions	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 and nine months ended September 30, 2017 and 2016 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 2016 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.
Investments Policy	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 has a 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.
Derivative Instruments Policy	The Company accounts for the interest rate swaps as non-hedge
Fair Value Measurement Policy	The Company’s invested assets and derivative instruments 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. The following is a description of the valuation methodologies used by the Company’s pricing vendors for investment securities carried at fair value: • Common stock 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. • Data from commercial vendors is aggregated with market information, then converted into a prepayment/spread/LIBOR curve model used for commercial mortgage obligations (“CMO”). CMOs are categorized with mortgage-backed securities in the tables listed above. For asset-backed securities, data derived from market information along with trustee and servicer reports is converted into spreads to interpolated swap yield curve. For both asset classes, evaluations utilize standard inputs plus new issue data, monthly payment information, and collateral performance. The evaluated pricing models incorporate discount rates, loan level information, prepayment speeds, treasury benchmarks, and LIBOR and swap curves. • For obligations of state and political subdivisions, a multi-dimensional relational model is used to evaluate securities. The pricing models incorporate security set-up, • U.S. treasuries are evaluated by obtaining feeds from a number of live data sources including active market makers and inter-dealer brokers. • For mortgage-backed securities, 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. Generally, during interim periods, the Company will divide total estimated annual income tax expense by total estimated annual pre-tax pre-tax
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 Policy	Earnings per share have been computed using the weighted average number of ordinary shares and ordinary share equivalents outstanding during the period.
