Organization Consolidation And Presentation Of Financial Statements [Abstract]
Principles of Consolidation and Basis of Presentation	1. Global Indemnity Limited (“Global Indemnity” or “the Company”) was incorporated on February 9, 2016 and 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. See Note 2 below for details regarding the redomestication. In connection with the redomestication, Global Indemnity plc was converted to a private unlimited company and was placed into liquidation. The liquidation was finalized in 2017. 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 primarily 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, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. The Company’s Reinsurance Operations consist solely of the operations of its Bermuda-based wholly-owned subsidiary, 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 The consolidated financial statements 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. On January 1, 2018, the Company adopted new accounting guidance which requires equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income. Upon adoption, the Company recorded a cumulative effect adjustment, net of tax, of $10.0 million which reduced accumulated other comprehensive income and increased retained earnings. During the year ended December 31, 2018, net realized investment gains (losses) included a loss of $22.0 million related to the change in the fair value of equity investments in accordance with this new accounting guidance. In addition, under the new guidance, equity investments, are no longer classified into different categories as either trading or available for sale. Prior to the adoption of this new guidance, equity securities were previously classified as available for sale. On January 1, 2018, the Company adopted new accounting guidance regarding the classification of certain cash receipts and cash payments within the statement of cash flows. Upon adoption, the Company made a policy election to use the cumulative earnings approach for presenting distributions received from equity method investees. Under this approach, distributions up to the amount of cumulative equity in earnings recognized will be treated as returns on investment and presented in operating activities and those in excess of that amount will be treated as returns of investment and presented in the investing section. Prior to adoption, all distributions received from equity method investees were presented in the investing section of the consolidated statements of cash flows. The provisions of this accounting guidance were adopted on a retrospective basis. As a result, the consolidated statement of cash flows for the years ended December 31, 2017 and 2016 that was included in the Form 10-K for the years ended December 31, 2017 and 2016 was restated. For the years ended December 31, 2017 and 2016, net cash flows from operating activities was increased by $4.7 million and $5.2 million, respectively, and net cash flows from investing activities was reduced by $4.7 million and $5.2 million, respectively. 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.

Redomestication [Abstract]
Redomestication	2. Redomestication On June 20, 2016, the Company’s Board of Directors unanimously approved a plan for the Company to redomicile from Ireland to the Cayman Islands. On September 14, 2016, the Company held a special meeting of the holders of its A ordinary shares and B ordinary shares and an extraordinary general meeting of its shareholders. All resolutions required to effectuate the redomestication were approved by the requisite shareholder vote. On October 21, 2016, the High Court of Ireland sanctioned Global Indemnity plc’s scheme of arrangement related to the redomestication from Ireland to Cayman Islands. The redomestication transaction was completed on November 7, 2016 and as a result, Global Indemnity Limited, a Cayman Islands exempted company, replaced Global Indemnity plc as the ultimate holding company of the Global Indemnity group of companies. In connection with the redomestication to the Cayman Islands, each A ordinary share of Global Indemnity plc was cancelled and replaced with one A ordinary share of Global Indemnity Limited and each B ordinary share of Global Indemnity plc was cancelled and replaced with one B ordinary share of Global Indemnity Limited. The Global Indemnity Limited A ordinary shares trade on the NASDAQ Global Select Market (“NASDAQ”) under the ticker symbol GBLI, the same symbol under which Global Indemnity plc’s A ordinary shares were previously listed.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Investments The Company’s investments in fixed maturities, which are classified as available for sale, and equity securities are carried at their fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair values of the Company's fixed maturities and equity securities are determined on the basis of quoted market prices where available. If quoted market prices are not available, the Company uses third party pricing services to assist in determining fair value. In many instances, these services examine the pricing of similar instruments to estimate fair value. The Company purchases bonds with the expectation of holding them to their maturity; however, changes to the portfolio are sometimes required to assure it is appropriately matched to liabilities. In addition, changes in financial market conditions and tax considerations may cause the Company to sell an investment before it matures. The difference between amortized cost and fair value of the Company’s fixed maturity portfolio, net of the effect of deferred income taxes, is reflected in accumulated other comprehensive income in shareholders’ equity and, accordingly, has no effect on net income other than for the credit loss component of impairments deemed to be other than temporary. Equity securities are measured at fair value with the changes in fair value recognized in net income. For investments in limited liability companies and limited partnerships where the ownership interest is less than 3%, the Company carries these investments at fair value, and the change in the difference between cost and the fair value of the partnership interests, net of the effect of deferred income taxes, is reflected in accumulated other comprehensive income in shareholders' equity and, accordingly, has no effect on net income other than for impairments deemed to be other than temporary. 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 or limited partnership requires that its cost basis be updated to account for the income or loss earned on the investment. The income or loss associated with the limited liability companies or limited partnerships is reflected in the consolidated statements of operations, and the adjusted cost basis approximates fair value. The Company’s investments in other invested assets were valued at $50.8 million and $77.8 million as of December 31, 2018 and 2017, respectively. These amounts relate to investments in limited liability companies and limited partnerships. The Company does not have access to daily valuations, therefore; the estimated fair value of the limited liability companies and limited partnerships are based on net asset value as a practical expedient for the limited liability companies and limited partnerships. Net realized gains and losses on investments are determined based on the first-in, first-out method. 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. Prior to the implementation of new accounting guidance on January 1, 2018, management carefully reviewed all equities securities with unrealized losses to determine if a security should be impaired and further focuses on securities that had either: (1) persisted with unrealized losses for more than twelve consecutive months or (2) the value of the investment had been 20% or more below cost for six continuous months or more. On January 1, 2018, the Company adopted new accounting guidance which requires equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income. 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. For an analysis of other than temporary losses that were recorded for the years ended December 31, 2018, 2017, and 2016, please see Note 4 below. 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 two VIEs 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. Cash and Cash Equivalents For the purpose of the statements of cash flows, the Company considers all liquid instruments with an original maturity of three months or less to be cash equivalents. The Company has a cash management program that provides for the investment of excess cash balances primarily in short-term money market instruments. Generally, bank balances exceed federally insured limits. The carrying amount of cash and cash equivalents approximates fair value. At December 31, 2018 and 2017, the Company had approximately $77.4 million and $67.1 million, respectively, of cash and cash equivalents that was invested in a diversified portfolio of high quality short-term debt securities. Valuation of Premium Receivable The Company evaluates the collectability of premium receivable based on a combination of factors. In instances in which the Company is aware of a specific circumstance where a party may be unable to meet its financial obligations to the Company, a specific allowance for bad debts against amounts due is recorded to reduce the net receivable to the amount reasonably believed by management to be collectible. For all remaining balances, allowances are recognized for bad debts based on the length of time the receivables are past due. The allowance for bad debts was $2.3 million and $2.2 million as of December 31, 2018 and 2017, respectively. Goodwill and Intangible Assets The Company tests for impairment of goodwill at least annually and more frequently as circumstances warrant in accordance with applicable accounting guidance. Accounting guidance allows for the testing of goodwill for impairment using both qualitative and quantitative factors. Impairment of goodwill is recognized only if the carrying amount of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. The amount of the impairment loss would be equal to the excess carrying value of the goodwill over the implied fair value of the reporting unit goodwill. Based on the qualitative assessment performed, t of as of December 31, 2018. Impairment of intangible assets with an indefinite at least annually and more frequently as circumstances warrant here were no impairments Intangible assets that are not deemed to have an indefinite useful life are amortized over their estimated useful lives. The carrying amounts of definite lived intangible assets are regularly reviewed for indicators of impairment in accordance with applicable accounting guidance. Impairment is recognized only if the carrying amount of the intangible asset is in excess of its undiscounted projected cash flows. The impairment is measured as the difference between the carrying amount and the estimated fair value of the asset. As of December 31, 2018, there were no triggering events that occurred during the year that would result in an impairment of definite lived intangible assets. See Note 7 for additional information on goodwill and intangible assets. Reinsurance In the normal course of business, the Company seeks to reduce the loss that may arise from events that cause unfavorable underwriting results by reinsuring certain levels of risk from various areas of exposure with reinsurers. Amounts receivable from reinsurers are estimated in a manner consistent with the reinsured policy and the reinsurance contract. The Company regularly reviews the collectability of reinsurance receivables. An allowance for uncollectible reinsurance receivable is recognized based on the financial strength of the reinsurers and the length of time any balances are past due. Any changes in the allowance resulting from this review are included in net losses and loss adjustment expenses on the consolidated statements of operations during the period in which the determination is made. The allowance for uncollectible reinsurance was $8.0 million as of December 31, 2018 and 2017. The applicable accounting guidance requires that the reinsurer must assume significant insurance risk under the reinsured portions of the underlying insurance contracts and that there must be a reasonably possible chance that the reinsurer may realize a significant loss from the transaction. The Company has evaluated its reinsurance contracts and concluded that each contract qualifies for reinsurance accounting treatment pursuant to this guidance. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. The deferred tax asset balance is analyzed regularly by management. This assessment requires significant judgment and considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of carryforward periods, and tax planning strategies and/or actions. Management believes that it is more likely than not that the results of future operations can generate sufficient taxable income to realize the remaining deferred income tax assets, and accordingly, the Company has not established any valuation allowances. Deferred Acquisition Costs The costs of acquiring new and renewal insurance and reinsurance contracts include commissions, premium taxes and certain other costs that are directly related to the successful acquisition of new and renewal insurance and reinsurance contracts. The excess of the Company’s costs of acquiring new and renewal insurance and reinsurance contracts over the related ceding commissions earned from reinsurers is capitalized as deferred acquisition costs and amortized over the period in which the related premiums are earned. The amortization of deferred acquisition costs for the years ended December 31, 2018, 2017, and 2016 was $118.0 million, $109.0 million, and $114.3 million, respectively. Premium Deficiency A premium deficiency is recognized if the sum of expected loss and loss adjustment expenses and unamortized acquisition costs exceeds related unearned premium after consideration of investment income. This evaluation is done at a distribution and product line level in Insurance Operations and at a treaty level in Reinsurance Operations. Any future expected loss on the related unearned premium is recorded first by impairing the unamortized acquisition costs on the related unearned premium followed by an increase to loss and loss adjustment expense reserves on additional expected loss in excess of unamortized acquisition costs. No premium deficiency reserve existed as of December 31, 2018 or 2017. Derivative Instruments The Company uses derivative instruments to manage its exposure to cash flow variability from interest rate risk. The derivative instruments are carried on the balance sheet at fair value and included in other assets and other liabilities. Changes in the fair value of the derivative instruments and the periodic net interest settlements under the derivatives instruments are recognized as net realized investment gains (losses) on the consolidated statements of operations. Margin Borrowing Facility The carrying amounts reported in the balance sheet represent the outstanding borrowings. The outstanding borrowings are due on demand; therefore, the cash receipts and cash payments related to the margin borrowing facility are shown net in the consolidated statements of cash flows. Subordinated Notes The carrying amounts reported in the balance sheet represent the outstanding balances, net of deferred issuance cost. See Note 11 for details. Unpaid Losses and Loss Adjustment Expenses The liability for unpaid losses and loss adjustment expenses represents the Company’s best estimate of future amounts needed to pay losses and related settlement expenses with respect to events insured by the Company. This liability is based upon the accumulation of individual case estimates for losses reported prior to the close of the accounting period with respect to direct business, estimates received from ceding companies with respect to assumed reinsurance, and estimates of unreported losses. The process of establishing the liability for unpaid losses and loss adjustment is complex, requiring the use of informed actuarially based estimates and management’s judgment. In some cases, significant periods of time, up to several years or more, may elapse between the occurrence of an insured loss and the reporting of that loss to the Company. To establish this liability, the Company regularly reviews and updates the methods of making such estimates and establishing the resulting liabilities. Any resulting adjustments are recorded in consolidated statements of operations during the period in which the determination is made. Retirement of Treasury Stock Upon the formal retirement of treasury stock, the Company offsets the par value of the treasury stock that is being retired against Ordinary Shares and reflects any excess of cost over par value as a deduction from Additional Paid-in Capital. Share Redemptions When shares are redeemed, the Company offsets the par value of the redeemed shares against Ordinary Shares and reflects any excess of cost over par value as a deduction from Retained Earnings. Premiums Premiums are recognized as revenue ratably over the term of the respective policies and treaties. Unearned premiums are computed on a pro rata basis to the day of expiration. Mandatory reinstatement premiums assessed on reinsurance policies are earned in the period of the loss event that gave rise to the reinstatement premiums. Contingent Commissions Certain professional general agencies of the Insurance Operations are paid special incentives, referred to as contingent commissions, when results of business produced by these agencies are more favorable than predetermined thresholds. Similarly, in some circumstances, companies that cede business to the Reinsurance Operations are paid profit commissions based on the profitability of the ceded portfolio. These commissions are charged to other underwriting expenses when incurred. Share-Based Compensation The Company accounts for stock options and other equity based compensation using the modified prospective application of the fair value-based method permitted by the appropriate accounting guidance. See Note 15 for details. Earnings per Share Basic earnings per share have been calculated by dividing net income available to common shareholders by the weighted-average ordinary shares outstanding. In periods of net income, diluted earnings per share have been calculated by dividing net income available to common shareholders by the sum of the weighted-average ordinary shares outstanding and the weighted-average common share equivalents outstanding, which include options and other equity awards. In periods of net loss, diluted earnings per share is the same as basic earnings per share. See Note 17 for details. Foreign Currency The Company maintains investments and cash accounts in foreign currencies related to the operations of its business. At period-end, the Company re-measures non-U.S. currency financial assets to their current U.S. dollar equivalent. The resulting gain or loss for foreign denominated fixed maturity investments is reflected in accumulated other comprehensive income in shareholders’ equity; whereas, the gain or loss on foreign denominated cash accounts and equity securities is reflected in income during the period. Financial liabilities, if any, are generally adjusted within the reserving process. However, for known losses on claims to be paid in foreign currencies, the Company re-measures the liabilities to their current U.S. dollar equivalent each period end with the resulting gain or loss reflected in income during the period. Net transaction gains and losses, primarily comprised of re-measurement of known losses on claims to be paid in foreign currencies, were a loss Other Income On September 30, 2016, Diamond State Insurance Company sold all the outstanding shares of capital stock of one of its wholly owned subsidiaries, United National Specialty Insurance Company, to an unrelated party. Diamond State Insurance Company received a one-time payment of $18.7 million and recognized a pretax gain of $6.9 million which is reflected in other income in 2016. This transaction did not have an impact on the Company’s ongoing business operations. Subsequent to the sale, any business previously written by United National Specialty Insurance Company is being written by other companies within the Company’s U.S. Insurance Operations. In addition, in 2018, other income is primarily comprised of fee income and foreign exchange gains and losses. In 2017, other income is comprised of fee income on policies issued, commission income, accrued interest on the anticipated indemnification of unpaid loss and loss adjustment expense reserve, and foreign exchange gains and losses.

The Company has analyzed these securities and has determined that they are not other than temporarily impaired. Subject to the risks and uncertainties in evaluating the potential impairment of a security’s value, the impairment evaluation conducted by the Company as of December 31, 2018 concluded the unrealized losses discussed above are not other than temporary impairments. The impairment evaluation process is discussed in the “Investment” section of Note 3 (“Summary of Significant Accounting Policies”). 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 December 31, 2018, gross unrealized losses related to U.S. treasury and agency obligations were $1.163 million. All unrealized losses have been in an unrealized loss position for twelve months or greater and are rated AA+. Macroeconomic and market analysis is conducted in evaluating these securities. Consideration is given to the interest rate environment, duration and yield curve management of the portfolio, sector allocation and security selection. Obligations of states and political subdivisions – As of December 31, 2018, gross unrealized losses related to obligations of states and political subdivisions were $0.338 million. Of this amount, $0.281 million have been in an unrealized loss position for twelve months or greater and are rated investment grade 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 December 31, 2018, gross unrealized losses related to mortgage-backed securities were $1.786 million. Of this amount, $1.378 million have been in an unrealized loss position for twelve months or greater. 99.1% of the unrealized losses for twelve months or greater are related to securities rated AA+ or better. 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. These forecasts incorporate not just national macro-economic trends, but also regional impacts to arrive at the most granular and accurate projections. These assumptions are incorporated into the model as a basis to generate delinquency probabilities, default curves, loss severity curves, and voluntary prepayment curves at the loan level within each deal. The model utilizes HPI-adjusted current LTV, payment history, loan terms, loan modification history, and borrower characteristics as inputs to generate expected cash flows and principal loss for each bond under various scenarios. Asset backed securities (“ABS”) - As of December 31, 2018, gross unrealized losses related to asset backed securities were $2.012 million. Of this amount, $0.670 million have been in an unrealized loss position for twelve months or greater. 93.7% of the unrealized losses for twelve months or greater are related to securities rated investment grade or better. The weighted average credit enhancement for the Company’s asset backed portfolio is 23.0. 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 December 31, 2018, gross unrealized losses related to the CMBS portfolio were $3.852 million. Of this amount, $2.974 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 CMBS portfolio is 47.9. 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. Each loan is analyzed over time using a series of tests to determine if a credit event will occur during the life of the loan. Inherent in this process are several economic scenarios and their corresponding rent/vacancy and capital market states. The five primary credit events that frame the analysis include loan modifications, term default, balloon default, extension, and ability to pay off at balloon. The resulting output is the expected loss adjusted cash flows for each bond under the base case and distressed scenarios. Corporate bonds - As of December 31, 2018, gross unrealized losses related to corporate bonds were $12.080 million. Of this amount, $3.289 million have been in an unrealized loss position for twelve months or greater. 88.7% of the unrealized losses for twelve months or greater are related to securities rated investment grade or better. The analysis for this asset class 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 December 31, 2018, gross unrealized losses related to foreign bonds were $3.292 million. Of this amount, $1.497 million have been in an unrealized loss position for twelve months or greater. 69.5% of the unrealized losses for twelve months or greater are related to securities rated investment grade or better. For this asset class, 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.

Approximately $0.7 million of these securities were tax-free municipal bonds, which represented less than 0.1% 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.” None of these bonds are pre-refunded with U.S. treasury securities, nor would they have carried a lower credit rating had they not been insured. A summary of the Company’s insurance enhanced municipal bonds that are backed by financial guarantors, including the pre-refunded bonds that are escrowed in U.S. government obligations, as of December 31, 2018, is as follows: (Dollars in thousands) Financial Guarantor Total Pre-refunded Securities Government Guaranteed Securities Exposure Net of Pre-refunded & Government Guaranteed Securities Municipal Bond Insurance Association $ 699 $ — $ — $ 699 Gov't National Housing Association — — — — Total backed by financial guarantors 699 — — 699 Other credit enhanced municipal bonds — — — — Total $ 699 $ — $ — $ 699 In addition to the tax-free municipal bonds, the Company held $32.9 million of insurance enhanced bonds, which represented approximately 2.2% of the Company’s total invested assets, net of receivable/payable for securities purchased and sold. The insurance enhanced bonds are comprised of $19.7 million of taxable municipal bonds, $13.0 million of commercial mortgage-backed securities, and $0.2 million of collateralized mortgage obligations. The financial guarantors of the Company’s $32.9 million of insurance enhanced commercial-mortgage-backed, taxable municipal securities, and collateralized mortgage obligations include Municipal Bond Insurance Association ($5.1 million), Assured Guaranty Corporation ($14.6 million), Federal Home Loan Mortgage Corporation ($13.0 million), and Federal Deposit Insurance Corporation ($0.2 million). The Company had no direct investments in the entities that have provided financial guarantees or other credit support to any security held by the Company at December 31, 2018. Bonds Held on Deposit Certain cash balances, cash equivalents, equity securities, and bonds available for sale were deposited with various governmental authorities in accordance with statutory requirements, were held as collateral pursuant to borrowing arrangements, or were held in trust pursuant to intercompany reinsurance agreements. The fair values were as follows as of December 31, 2018 and 2017: Estimated Fair Value (Dollars in thousands) December 31, 2018 December 31, 2017 On deposit with governmental authorities $ 25,855 $ 26,852 Intercompany trusts held for the benefit of U.S. policyholders 209,028 328,494 Held in trust pursuant to third party requirements 98,417 94,098 Letter of credit held for third party requirements 2,317 3,944 Securities held as collateral for borrowing arrangements (1) 83,214 88,040 Total $ 418,831 $ 541,428 (1) Amount required to collateralize margin borrowing facility. 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 two 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 $17.9 million and $26.3 million as of December 31, 2018 and 2017, respectively. The Company’s maximum exposure to loss from this VIE, which factors in future funding commitments, was $32.1 million and $40.5 million at December 31, 2018 and 2017, respectively.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	5. 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. The Company accounts for the interest rate swaps as non-hedge instruments and 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 or losses in the consolidated statements of operations. The Company is ultimately responsible for the valuation of the interest rate swaps. To aid in determining the estimated fair value of the interest rate swaps, the Company relies on the forward interest rate curve and information obtained from a third party financial institution. The following table summarizes information on the location and the gross amount of the derivatives’ fair value on the consolidated balance sheets as of December 31, 2018 and 2017: (Dollars in thousands) December 31, 2018 December 31, 2017 Derivatives Not Designated as Hedging Instruments under ASC 815 Balance Sheet Location Notional Amount Fair Value Notional Amount Fair Value Interest rate swap agreements Other assets/liabilities $ 200,000 $ (4,062 ) $ 200,000 $ (7,968 ) The following table summarizes the net gains (losses) included in the consolidated statements of operations for changes in the fair value of the derivatives and the periodic net interest settlements under the derivatives for the years ended December 31, 2018, 2017, and 2016: Consolidated Statements of Years Ended December 31, (Dollars in thousands) Operations Line 2018 2017 2016 Interest rate swap agreements Net realized investment gains (losses) $ 2,117 $ (75 ) $ (1,110 ) As of December 31, 2018 and 2017, the Company is due $2.6 million and $3.1 million, respectively, for funds it needed to post to execute the swap transaction and $3.7 million and $9.5 million, respectively, for margin calls made in connection with the interest rate swaps. These amounts are included in other assets on the consolidated balance sheets.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. 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 December 31, 2018 and 2017, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. As of December 31, 2018 Fair Value Measurements (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets: Fixed maturities: U.S. treasury and agency obligations $ 78,855 $ — $ — $ 78,855 Obligations of states and political subdivisions — 95,613 — 95,613 Mortgage-backed securities — 117,854 — 117,854 Commercial mortgage-backed securities — 202,722 — 202,722 Asset-backed securities — 183,754 — 183,754 Corporate bonds — 440,855 — 440,855 Foreign corporate bonds — 115,502 — 115,502 Total fixed maturities 78,855 1,156,300 — 1,235,155 Common stock 124,747 — — 124,747 Total assets measured at fair value (1) $ 203,602 $ 1,156,300 $ — $ 1,359,902 Liabilities: Derivative instruments $ — $ 4,062 $ — $ 4,062 Total Liabilities measured at fair value $ — $ 4,062 $ — $ 4,062 (1) Excluded from the table above are limited partnerships of $50.8 million at December 31, 2018 whose fair value is based on net asset value as a practical expedient. As of December 31, 2017 Fair Value Measurements (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets: Fixed maturities: U.S. treasury and agency obligations $ 104,680 $ — $ — $ 104,680 Obligations of states and political subdivisions — 95,114 — 95,114 Mortgage-backed securities — 149,350 — 149,350 Commercial mortgage-backed securities — 139,795 — 139,795 Asset-backed securities — 203,701 — 203,701 Corporate bonds — 423,390 — 423,390 Foreign corporate bonds — 125,407 — 125,407 Total fixed maturities 104,680 1,136,757 — 1,241,437 Common stock 140,229 — — 140,229 Total assets measured at fair value (1) $ 244,909 $ 1,136,757 $ — $ 1,381,666 Liabilities: Derivative instruments $ — $ 7,968 $ — $ 7,968 Total liabilities measured at fair value $ — $ 7,968 $ — $ 7,968 (1) Excluded from the table above are limited partnerships of $77.8 million at December 31, 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 December 31, 2018 and 2017 was as follows: December 31, 2018 December 31, 2017 (Dollars in thousands) Carrying Value Fair Value Carrying Value Fair Value Margin Borrowing Facility $ 65,818 $ 65,818 $ 72,230 $ 72,230 7.75% Subordinated Notes due 2045 (1) 96,742 92,261 96,619 100,059 7.875% Subordinated Notes due 2047 (2) 126,005 120,597 125,864 130,429 Total $ 288,565 $ 278,676 $ 294,713 $ 302,718 (1) As of December 31, 2018 and 2017, the carrying value and fair value of the 7.75% Subordinated Notes due 2045 are net of unamortized debt issuance cost of $3.3 million and $3.4 million, respectively. (2) As of December 31, 2018 and 2017, the carrying value and fair value of the 7.875% Subordinated Notes due 2047 are net of unamortized debt issuance cost of $4.0 million and $4.1 million, respectively. 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 years ended December 31, 2018, 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 practical expedient. The following table provides the fair value and future funding commitments related to these investments at December 31, 2018 and 2017.

The Company does not have the ability to sell or transfer its limited partnership interest without consent from the general partner. The Company continues to hold an investment in this limited partnership and has written the fair value down to zero. (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 and 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 partnership agreement, the Company anticipates its interest in this partnership to be redeemed by 2020. (3) This limited partnership provides financing for middle market companies. During the fourth quarter of 2018 the Company received permission from the general partner to divest from the limited partnership and subsequently sold its interest. (4) This limited partnership invests in stressed and distressed securities and structured products.

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 associated with these limited liability companies or limited partnerships, which is reflected in the consolidated statements of operations, was $6.9 million, $4.7 million, and $5.2 million for the years ended December 31, 2018, 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 terms and conditions sourced from commercial vendors. Bonds with similar characteristics are grouped into specific sectors. Both asset classes use standard inputs and utilize bid price or spread, quotes, benchmark yields, discount rates, market data feeds, and financial statements. • 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 benchmark 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, an integrated evaluation system is used. The pricing models incorporate trades, spreads, benchmark curves, market data feeds, new issue data, and trustee reports. • 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, various external analytical products are utilized and purchased from commercial vendors. 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. This procedure allows the Company to understand why a particular security’s market value may have changed or may potentially change. • 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 2018 and 2017, the Company has not adjusted quotes or prices obtained from the pricing vendors.

Intangible assets with definite lives As of December 31, 2018 and 2017, definite lived intangible assets, net of accumulated amortization, were $3.0 million and $3.5 million, respectively, and were comprised of customer relationships, agent relationships, and tradenames. The Company reviewed internal business unit results, the growth of competitors and the overall property and casualty insurance market for indicators of impairment of its definite lived intangible assets. There was no impairment of these assets in 2018 or 2017.

Insurance [Abstract]
Reinsurance	8. Reinsurance The Company cedes risk to unrelated reinsurers on a pro rata (“quota share”) and excess of loss basis in the ordinary course of business to limit its net loss exposure on insurance contracts. Reinsurance ceded arrangements do not discharge the Company of primary liability. Moreover, reinsurers may fail to pay the Company due to a lack of reinsurer liquidity, perceived improper underwriting, and losses for risks that are excluded from reinsurance coverage and other similar factors, all of which could adversely affect the Company’s financial results. The Company had the following reinsurance balances as of December 31, 2018 and 2017: (Dollars in thousands) December 31, 2018 December 31, 2017 Reinsurance receivables, net $ 114,418 $ 105,060 Collateral securing reinsurance receivables (11,347 ) (6,584 ) Reinsurance receivables, net of collateral $ 103,071 $ 98,476 Allowance for uncollectible reinsurance receivables $ 8,040 $ 8,040 Prepaid reinsurance premiums 20,594 28,851 The reinsurance receivables above are net of a purchase accounting adjustment related to discounting acquired loss reserves to their present value and applying a risk margin to the discounted reserves. This adjustment was $0.8 million and $1.2 million at December 31, 2018 and 2017, respectively. As of December 31, 2018, the Company had one aggregate unsecured reinsurance receivables that exceeded 3% of shareholders’ equity from the following reinsurer.

Income Taxes	9. Income Taxes As of December 31, 2018, the statutory income tax rates of the countries where the Company conducts business are 21% in the United States, 0% in Bermuda, 0% in the Cayman Islands, 26.01% for companies with a registered office in Luxembourg City, 0.25% to 2.5% in Barbados, and 25% on non-trading income, 33% 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 annual taxable income of each country to calculate the annual income tax expense. The Company’s income before income taxes from its non-U.S. subsidiaries and U.S. subsidiaries for the years ended December 31, 2018, 2017, and 2016 were as follows: Year Ended December 31, 2018 (Dollars in thousands) Non-U.S. Subsidiaries U.S. Subsidiaries Eliminations Total Revenues: Gross premiums written $ 48,050 $ 499,847 $ - $ 547,897 Net premiums written $ 48,041 $ 424,506 $ - $ 472,547 Net premiums earned $ 135,826 $ 331,949 $ - $ 467,775 Net investment income 49,699 27,294 (30,651 ) 46,342 Net realized investment losses (669 ) (16,238 ) - (16,907 ) Other income (loss) (210 ) 1,938 - 1,728 Total revenues 184,646 344,943 (30,651 ) 498,938 Losses and Expenses: Net losses and loss adjustment expenses 91,178 243,447 - 334,625 Acquisition costs and other underwriting expenses 57,487 133,291 - 190,778 Corporate and other operating expenses 12,234 17,532 - 29,766 Interest expense 7,108 43,237 (30,651 ) 19,694 Income (loss) before income taxes $ 16,639 $ (92,564 ) $ - $ (75,925 ) Year Ended December 31, 2017 (Dollars in thousands) Non-U.S. Subsidiaries U.S. Subsidiaries Eliminations Total Revenues: Gross premiums written $ 212,386 $ 462,453 $ (158,505 ) $ 516,334 Net premiums written $ 212,432 $ 237,748 $ — $ 450,180 Net premiums earned $ 201,165 $ 236,869 $ — $ 438,034 Net investment income 56,890 24,609 (42,176 ) 39,323 Net realized investment gains (losses) (641 ) 2,217 — 1,576 Other income 216 6,366 — 6,582 Total revenues 257,630 270,061 (42,176 ) 485,515 Losses and Expenses: Net losses and loss adjustment expenses 94,903 174,309 — 269,212 Acquisition costs and other underwriting expenses 89,153 94,580 — 183,733 Corporate and other operating expenses 17,399 8,315 — 25,714 Interest expense 16,740 42,342 (42,176 ) 16,906 Income (loss) before income taxes $ 39,435 $ (49,485 ) $ — $ (10,050 ) Year Ended December 31, 2016 (Dollars in thousands) Non-U.S. Subsidiaries U.S. Subsidiaries Eliminations Total Revenues: Gross premiums written $ 201,726 $ 506,061 $ (141,942 ) $ 565,845 Net premiums written $ 201,690 $ 269,250 $ — $ 470,940 Net premiums earned $ 212,325 $ 256,140 $ — $ 468,465 Net investment income 48,807 19,341 (34,165 ) 33,983 Net realized investment gains (losses) (89 ) 21,810 — 21,721 Other income (loss) (224 ) 10,569 — 10,345 Total revenues 260,819 307,860 (34,165 ) 534,514 Losses and Expenses: Net losses and loss adjustment expenses 95,812 168,191 — 264,003 Acquisition costs and other underwriting expenses 94,749 101,901 — 196,650 Corporate and other operating expenses 9,035 8,303 — 17,338 Interest expense 8,312 34,758 (34,165 ) 8,905 Income (loss) before income taxes $ 52,911 $ (5,293 ) $ — $ 47,618 For the years ended December 31, 2017 and 2016, the Company’s income (loss) before income taxes from its non-U.S. subsidiaries and U.S. subsidiaries, as reported in the table above, includes the results of the quota share agreement between Global Indemnity Reinsurance and the Insurance Operations. This quota share agreement was cancelled on a runoff basis effective January 1, 2018. The following table summarizes the components of income tax benefit: Years Ended December 31, (Dollars in thousands) 2018 2017 2016 Current income tax expense: Foreign $ 325 $ 392 $ 330 U.S. Federal — 127 147 Total current income tax expense 325 519 477 Deferred income tax expense (benefit): U.S. tax rate change — 17,524 — U.S. Federal (19,554 ) (18,542 ) (2,727 ) Total deferred income tax expense (benefit) (19,554 ) (1,018 ) (2,727 ) Total income tax benefit $ (19,229 ) $ (499 ) $ (2,250 ) The weighted average expected tax provision has been calculated using income (loss) before income taxes in each jurisdiction multiplied by that jurisdiction’s applicable statutory tax rate. The following table summarizes the differences between the tax provision for financial statement purposes and the expected tax provision at the weighted average tax rate: Years Ended December 31, 2018 2017 2016 (Dollars in thousands) Amount % of Pre- Tax Income Amount % of Pre- Tax Income Amount % of Pre- Tax Income Expected tax provision at weighted average $ (19,112 ) (25.2 %) $ (16,928 ) (168.4 %) $ (1,496 ) (3.1 %) Adjustments: Tax exempt interest (6 ) (0.0 %) (213 ) (2.1 ) (394 ) (0.8 ) Dividend exclusion (279 ) (0.4 %) (571 ) (5.7 ) (617 ) (1.3 ) Tax rate change — (— %) 17,524 174.4 — — Non-deductible interest 356 0.5 % — — — — Other (188 ) (0.2 %) (311 ) (3.2 ) 257 0.5 Effective income tax benefit $ (19,229 ) (25.3 %) $ (499 ) (5.0 %) $ (2,250 ) (4.7 %) The effective income tax benefit rate for 2018 was 25.3%, compared with an effective income tax benefit rate of 5.0% and 4.7% for 2017 and 2016, respectively. The increase in the effective income tax benefit rate in 2018 compared to 2017 is due to a $17.5 million tax expense recorded in 2017 as a result of the TCJA enacted in 2017 resulting in lowering the tax rate from 35% to 21% offset by an increase in losses incurred by the Company’s non-U.S. operations in 2018 compared to 2017. The increase in the effective income tax benefit rate in 2017 compared to 2016 is due to incurring a provisional tax expense of $17.5 million related to the reduction in the deferred tax asset as a result of the TCJA enacted on December 22, 2017 which lowered the U.S. tax rate from 35% to 21% offset by $18.4 million tax benefit due to an increase in losses incurred in the Company’s U.S. operations for 2017 compared to 2016. The tax effects of temporary differences that give rise to significant portions of the net deferred tax assets at December 31, 2018 and 2017 are presented below: (Dollars in thousands) 2018 2017 Deferred tax assets: Discounted unpaid losses and loss adjustment expenses $ 3,482 $ 3,625 Unearned premiums 9,206 5,318 Section 163(j) carryforward 11,075 7,906 Net operating loss carryforward 29,480 16,323 Partnership K1 basis differences 113 130 Gain on derivative instruments 853 1,673 Investment impairments 816 1,742 Stock options 1,375 1,740 Stat-to-GAAP reinsurance reserve 895 1,014 Unrealized loss on securities available-for-sale and investments in limited partnerships included in accumulated other comprehensive income 2,778 - Unrealized loss on equity securities 1,409 - Intercompany transfers 210 317 Other 1,860 3,249 Total deferred tax assets 63,552 43,037 Deferred tax liabilities: Purchase accounting adjustment for American Reliable - 7,723 Intangible assets 3,150 2,394 Unrealized gain on securities available-for-sale and investments in limited partnerships included in accumulated other comprehensive income - 3,105 Investment basis differences 212 211 Deferred acquisition costs 10,525 1,921 Depreciation and amortization 528 285 Other 548 1,202 Total deferred tax liabilities 14,963 16,841 Total net deferred tax assets $ 48,589 $ 26,196 The deferred tax assets and deferred tax liabilities listed in the table above relate to temporary differences between the Company’s accounting and tax carrying values and carryforwards for its companies in the United States. Management believes it is more likely than not that the remaining deferred tax assets will be completely utilized in future years. As a result, the Company has not recorded a valuation allowance at December 31, 2018 and 2017. The Company has a net operating loss (“NOL”) carryforward of $29.5 million as of December 31, 2018, which begins to expire in 2035 based on when the original NOL was generated. The Company’s NOL carryforward as of December 31, 2017 was $16.3 million. The Company has a Section 163(j) (“163(j)”) carryforward of $11.1 million and $7.9 million as of December 31, 2018 and 2017, respectively, which can be carried forward indefinitely. The 163(j) carryforward is for disqualified interest paid or accrued to a related entity that is not subject to U.S. tax. The Company had an alternative minimum tax (“AMT”) credit carryforward of $11.0 million as of December 31, 2017. The TCJA repealed the corporate AMT. The AMT credit carryforward of $11.0 million was reclassed to federal income taxes receivable at December 31, 2017 and will be fully refunded by the end of 2021. The Company and some of its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. The Company is no longer subject to U.S. federal tax examinations by tax authorities for tax years before 2015. Should the Company’s subsidiaries that are subject to income taxes imposed by the U.S. authorities pay a dividend to their foreign affiliates, withholding taxes would apply. The Company has not recorded deferred taxes for potential withholding tax on undistributed earnings. The Company believes, although there can be no assurances, that it qualifies for treaty benefits under the Tax Convention with Luxembourg and would be subject to a 5% withholding tax if it were to pay a dividend. Determination of the unrecognized deferred tax liability related to these undistributed earnings is not practicable because of the complexities with its hypothetical calculation. The Company did not pay any dividends from a U.S. subsidiary to a foreign affiliate during 2018, 2017, or 2016. The Company applies a more-likely-than-not recognition threshold for all tax uncertainties whereby it only recognizes those tax benefits that have a greater than 50% likelihood of being sustained upon examination by the taxing authorities. All tax benefits recognized by the company in 2018, 2017, 2016 have a greater than 50% likelihood of being sustained upon examination by the taxing authorities. The Company classifies all interest and penalties related to uncertain tax positions as income tax expense. The Company did not incur any interest and penalties related to uncertain tax positions during the years ended December 31, 2018, 2017 and 2016. As of December 31, 2018, the Company did not record any liabilities for tax-related interest and penalties on its consolidated balance sheets.

Liability for Unpaid Losses and Loss Adjustment Expenses	10. Liability for Unpaid Losses and Loss Adjustment Expenses Consolidated Activity Activity in the liability for unpaid losses and loss adjustment expenses is summarized as follows: Years Ended December 31, (Dollars in thousands) 2018 2017 2016 Balance at beginning of period $ 634,664 $ 651,042 $ 680,047 Less: Ceded reinsurance receivables 97,243 130,439 108,130 Net balance at beginning of period 537,421 520,603 571,917 Purchased reserves, gross — 19,333 2,007 Less: Purchased reserves ceded — (29 ) (45 ) Purchase reserves, net of third party reinsurance — 19,362 2,052 Incurred losses and loss adjustment expenses related to: Current year 363,423 323,112 321,255 Prior years (28,798 ) (53,900 ) (57,252 ) Total incurred losses and loss adjustment expenses 334,625 269,212 264,003 Paid losses and loss adjustment expenses related to: Current year 173,545 156,325 177,006 Prior years 127,812 115,431 140,363 Total paid losses and loss adjustment expenses 301,357 271,756 317,369 Net balance at end of period 570,689 537,421 520,603 Plus: Ceded reinsurance receivables 109,342 97,243 130,439 Balance at end of period $ 680,031 $ 634,664 $ 651,042 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. During 2018, the Company reduced its prior accident year loss reserves by $28.8 million, which consisted of a $7.3 million decrease related to Commercial Lines, $12.6 million decrease related to Personal Lines, and a $8.9 million decrease related to Reinsurance Operations. The $7.3 million reduction of prior accident year loss reserves related to Commercial Lines primarily consisted of the following: • General Liability: A $1.3 million reduction • Commercial Auto Liability: A $3.2 million decrease in the aggregate primarily due to a reduction in the 2010, 2012 and 2013 accident years resulting from lower than anticipated claims severity partially offset by an increase in the 2015 and 2017 accident years. • Professional Liability: A $0.9 million decrease reflects lower than expected claims severity mainly in the 2008, 2011, and 2014 accident years • Property: A $1.9 million decrease The $12.6 million reduction of prior accident year loss reserves related to Personal Lines primarily consisted of the following: • Property: A $7.0 million reduction primarily due to lower than anticipated claims severity in the 2014 through 2017 accident years partially offset by an increase in the 2013 accident year. • General Liability: A $5.6 million decrease primarily due to lower than expected claims severity in the 2011 through 2014, 2016, and 2017 accident years partially offset by an increase in the 2007 and 2015 accident years. The $8.9 million reduction of prior accident year loss reserves related to Reinsurance Operations was from the property lines for accident years 2007, 2009 through 2012, 2015, and 2016 partially offset by increases in the 2013, 2014, and 2017 accident years. The accident year changes were based on a review of the experience reported from cedants. During 2017, the Company reduced its prior accident year loss reserves by $53.9 million, which consisted of a $39.4 million decrease related to Commercial Lines, $6.6 million decrease related to Personal Lines, and a $7.9 million decrease related to Reinsurance Operations. The $39.4 million reduction of prior accident year loss reserves related to Commercial Lines primarily consisted of the following: • General Liability: A $26.9 million reduction in aggregate with $6.9 million of favorable development in the construction defect reserve category and $20.0 million of favorable development in the other general liability reserve categories. The favorable development in the construction defect reserve category recognizes lower than anticipated claims frequency and severity which led to reductions primarily in the 2005 through 2016 accident years. For the other general liability reserve categories, lower than expected claims severity was the primary driver of the favorable development mainly in the 2005 through 2014 accident years. • Professional Liability: A $5.8 million decrease in aggregate primarily reflects lower than expected claims severity in the 2006 through 2008 and 2011 through 2012 accident years. • Property: A $6.3 million reduction in aggregate with $4.0 million of favorable development in the property excluding catastrophe reserve categories and $2.3 million of favorable development in the property catastrophe reserve categories. The favorable development in the reserve categories excluding catastrophe experience reflects lower than expected claims severity in the 2011 through 2015 accident years. For the property catastrophe reserve categories, lower than anticipated claims severity was the driver of the favorable development in the 2011 through 2016 accident years. • Workers Compensation: A $0.5 million reduction primarily due to lower than expected case incurred emergence in the 2011 accident year. The $6.6 million reduction of prior accident year loss reserves related to Personal Lines primarily consisted of the following: • Property: A $6.1 million reduction in the property reserve categories. The decrease reflects lower than expected case incurred emergence primarily in the 2016 accident year and favorable development from the Butte wildfire subrogation recovery in the 2015 accident year. • General Liability: A $0.5 million reduction reflects lower than expected case incurred emergence in the 2016 accident year, primarily in the agriculture reserve category, partially offset by adverse development in the 2015 accident year reflecting higher than anticipated case incurred emergence mainly in the dwelling reserve category. The $7.9 million reduction of prior accident year loss reserves related to Reinsurance Operations was primarily from the property lines for accident years 2008 through 2016. Ultimate losses were lowered in these accident years based on review of the experience reported from cedants. During 2016, the Company reduced its prior accident year loss reserves by $57.3 million, which consisted of a $43.8 million decrease related to Commercial Lines and a $13.5 million decrease related to Reinsurance Operations. The $43.8 million reduction of prior accident year loss reserves related to Commercial Lines primarily consisted of the following: • Property: A $0.8 million increase in aggregate with a $0.5 million increase in the non-catastrophe segments and $0.3 million increase in the catastrophe segments. The increases reflect higher than expected case incurred emergence, primarily in the 2009, 2012, and 2015 accident years. The increases were partially offset by decreases in the 2008, 2011, and 2013 accident years due to better than expected case incurred emergence in those accident years. • General Liability: A $43.8 million reduction in aggregate, within the casualty lines, with $9.4 million of favorable development in the construction defect reserve category and $34.4 million of favorable development in the other general liability reserve categories. For the construction defect reserve category, lower than expected frequency and severity led to favorable development in accident years 2005 through 2015. Lower than expected claims severity was the driver of the favorable development in the other general liability reserve categories, primarily in the 2004 through 2014 accident years. • Marine: A $1.4 million decrease in accident years 2010 through 2012 was driven by less than expected case incurred emergence in these years which is primarily within the casualty lines. The $13.5 million reduction of prior accident year loss reserves related to Reinsurance Operations was primarily from the property lines for accident years 2010 through 2015. Ultimate losses were lowered in these accident years based on reviews of the experience reported from cedants. Prior to 2001, the Company underwrote multi-peril business insuring general contractors, developers, and sub-contractors primarily involved in residential construction that has resulted in significant exposure to construction defect (“CD”) claims. The Company’s reserves for CD claims are established based upon management’s best estimate in consideration of known facts, existing case law and generally accepted actuarial methodologies. However, due to the inherent uncertainty concerning this type of business, the ultimate exposure for these claims may vary significantly from the amounts currently recorded. As of December 31, 2018 and 2017, gross reserves for CD claims were $42.4 million and $43.8 million, respectively, and net reserves for CD claims were $39.3 million and $40.2 million, respectively. The Company has exposure to asbestos and environmental (“A&E”) claims. The asbestos exposure primarily arises from the sale of product liability insurance, and the environmental exposure arises from the sale of general liability and commercial multi-peril insurance. In establishing the liability for unpaid losses and loss adjustment expenses related to A&E exposures, management considers facts currently known and the current state of the law and coverage litigation. Liabilities are recognized for known claims (including the cost of related litigation) when sufficient information has been developed to indicate the involvement of a specific insurance policy, and management can reasonably estimate its liability. In addition, liabilities have been established to cover additional exposures on both known and unasserted claims. Estimates of the liabilities are reviewed and updated regularly. Case law continues to evolve for such claims, and uncertainty exists about the outcome of coverage litigation and whether past claim experience will be representative of future claim experience. Included in net unpaid losses and loss adjustment expenses as of December 31, 2018, 2017, and 2016 were IBNR reserves of $27.4 million, $26.9 million, and $26.7 million, respectively, and case reserves of approximately $2.1 million, $3.3 million, and $3.2 million, respectively, for known A&E-related claims. The following table shows the Company’s gross reserves for A&E losses: Years Ended December 31, 2018 2017 2016 Gross reserve for A&E losses and loss adjustment expenses – beginning of period $ 51,873 $ 51,919 $ 53,824 Plus: Incurred losses and loss adjustment expenses – case reserves 341 542 (669 ) Plus: Incurred losses and loss adjustment expenses – IBNR (342 ) 928 2,064 Less: Payments 1,427 1,516 3,300 Gross reserves for A&E losses and loss adjustment expenses – end of period $ 50,445 $ 51,873 $ 51,919 The following table shows the Company’s net reserves for A&E losses: Years Ended December 31, (Dollars in thousands) 2018 2017 2016 Net reserve for A&E losses and loss adjustment expenses – beginning of period $ 30,124 $ 29,890 $ 30,529 Plus: Incurred losses and loss adjustment expenses – case reserves (511 ) 769 (125 ) Plus: Incurred losses and loss adjustment expenses – IBNR 511 198 631 Less: Payments 600 733 1,145 Net reserves for A&E losses and loss adjustment expenses – end of period $ 29,524 $ 30,124 $ 29,890 Establishing reserves for A&E and other mass tort claims involves more judgment than other types of claims due to, among other things, inconsistent court decisions, an increase in bankruptcy filings as a result of asbestos-related liabilities, and judicial interpretations that often expand theories of recovery and broaden the scope of coverage. The insurance industry continues to receive a substantial number of asbestos-related bodily injury claims, with an increasing focus being directed toward other parties, including installers of products containing asbestos rather than against asbestos manufacturers. This shift has resulted in significant insurance coverage litigation implicating applicable coverage defenses or determinations, if any, including but not limited to, determinations as to whether or not an asbestos-related bodily injury claim is subject to aggregate limits of liability found in most comprehensive general liability policies. As of December 31, 2018, 2017, and 2016, the survival ratio on a gross basis for the Company’s open A&E claims was 24.2 years, 20.7 years, and 13.8 years, respectively. As of December 31, 2018, 2017, and 2016, the survival ratio on a net basis for the Company’s open A&E claims was 35.7 years, 35.6 years, and 19.3 years, respectively. The survival ratio, which is the ratio of gross or net reserves to the 3-year average of annual paid claims, is a financial measure that indicates how long the current amount of gross or net reserves are expected to last based on the current rate of paid claims. Line of Business Categories The following is information, presented by lines of business with similar characteristics including similar payout patterns, about incurred and paid claims development as of December 31, 2018, net of reinsurance, as well as cumulative claim frequency and the total of incurred-but-not-reported liabilities included within the net incurred claims amounts. The years included represent the number of years for which claims incurred typically remain outstanding but need not exceed 10 years including the most recent report period presented.

Paid loss, ALAE and Case reserves, shown in the reinsurance category tables below, which are originally based in a foreign currency, are remeasured in U.S. dollars based on the Foreign Exchange (FX) rate at the end of the period.

Debt Disclosure [Abstract]
Debt	11. Debt The Company’s outstanding debt consisted of the following at December 31, 2018 and 2017: December 31, (Dollars in thousands) 2018 2017 Margin Borrowing Facility $ 65,818 $ 72,230 7.75% Subordinated Notes due 2045 96,742 96,619 7.875% Subordinated Notes due 2047 126,005 125,864 Total $ 288,565 $ 294,713 Margin Borrowing Facility The Company has available a margin borrowing facility. The borrowing rate for this facility is tied to the Fed Funds Effective rate and was approximately 2.7% and 1.6% at December 31, 2018 and 2017, respectively. This facility is due on demand. The borrowings are subject to maintenance margin, which is a minimum account balance that must be maintained. A decline in market conditions could require an additional deposit of collateral. As of December 31, 2018, approximately $83.2 million in securities were deposited as collateral to support borrowings. The amount borrowed against the margin account may fluctuate as routine investment transactions, such as dividends received, investment income received, maturities and pay-downs, impact cash balances. The margin facility contains customary events of default, including, without limitation, insolvency, failure to make required payments, failure to comply with any representations or warranties, failure to adequately assure future performance, and failure of a guarantor to perform under its guarantee. The amount outstanding on the Company’s margin borrowing facility was $65.8 million and $72.2 million as of December 31, 2018 and 2017, respectively. The Company recorded interest expense related to the Margin Borrowing Facility of approximately $1.4 million, $1.0 million, and $1.0 million for the years ended December 31, 2018, 2017, and 2016, respectively. 7.75% Subordinated Notes due 2045 On August 12, 2015, the Company issued $100.0 million in aggregate principal amount of its 2045 Subordinated Notes through an underwritten public offering (the “2045 Notes”). The 2045 Notes bear interest at an annual rate equal to 7.75%, payable quarterly in arrears on February 15, May 15, August 15, and November 15 of each year, commencing November 15, 2015. The 2045 Notes mature on August 15, 2045. The Company has the right to redeem the 2045 Notes in $25 increments, in whole or in part, on and after August 15, 2020, or on any interest payment date thereafter, at a redemption price equal to 100% of the principal amount of the 2045 Notes being redeemed plus accrued and unpaid interest to, but not including, the date of redemption. The 2045 Notes are subordinated unsecured obligations and rank (i) senior to the Company’s existing and future capital stock, (ii) senior in right of payment to future junior subordinated debt, (iii) equally in right of payment with any unsecured, subordinated debt that the Company incurs in the future that ranks equally with the 2045 Notes, and (iv) subordinate in right of payment to any of the Company’s existing and future senior debt. In addition, the 2045 Notes are structurally subordinated to all existing and future indebtedness, liabilities and other obligations of the Company’s subsidiaries. The 2045 Notes do not require the maintenance of any financial ratios or specified levels of net worth or liquidity, and do not contain provisions that would afford holders of the 2045 Notes protection in the event of a sudden and dramatic decline in the Company’s credit quality resulting from any highly leveraged transaction, reorganization, restructuring, merger or similar transaction involving the Company that may adversely affect holders. The 2045 Notes do not restrict the Company in any way, now or in the future, from incurring additional indebtedness, including senior indebtedness that would rank senior in right of payment to the 2045 Notes. There is no right of acceleration of maturity of the 2045 Notes in the case of default in the payment of principal, premium, if any, or interest on the 2045 Notes or in the performance of any other obligation of the Company under the 2045 Notes or if the Company defaults on any other debt securities. Holders may accelerate payment of indebtedness on the 2045 Notes only upon the Company’s bankruptcy, insolvency or reorganization. The Company incurred $3.7 million in deferred issuance costs associated with the 2045 Notes, which is being amortized over the term of the 2045 Notes. Interest expense, including amortization of deferred issuance costs, recognized on the 2045 Notes was $7.9 million for each of the years ended December 31, 2018, 2017, and 2016. 7.875% Subordinated Notes due 2047 On March 23, 2017, the Company issued Subordinated Notes due in 2047 in the aggregate principal amount of $120.0 million through an underwritten public offering (the “2047 Notes”). Pursuant to the underwriting agreement, the Company granted the underwriters a 30 day option to purchase up to an additional $18 million aggregate principal amount of the 2047 Notes solely to cover over-allotments, if any. On March 30, 2017, the underwriters exercised their over-allotment option in the amount of $10 million principal amount of the 2047 Notes. As a result, the aggregate principal amount of the 2047 Notes increased to $130.0 million. The sale of the 2047 Notes pursuant to the over-allotment option closed on March 30, 2017. The 2047 Notes bear interest at an annual rate equal to 7.875%, payable quarterly in arrears on January 15, April 15, July 15, and October 15 of each year, commencing July 15, 2017. The 2047 Notes mature on April 15, 2047. The Company has the right to redeem the 2047 Notes in $25 increments, in whole or in part, on and after April 15, 2022, or on any interest payment date thereafter, at a redemption price equal to 100% of the principal amount of the 2047 Notes being redeemed plus accrued and unpaid interest to, but not including, the date of redemption. If the Company redeems only a portion of the 2047 Notes on any date of redemption, the Company may subsequently redeem additional 2047 Notes. The 2047 Notes are subordinated unsecured obligations and rank (i) senior to the Company’s existing and future capital stock, (ii) senior in right of payment to future junior subordinated debt, (iii) equally in right of payment with any existing unsecured, subordinated debt that the Company has issued or may issue in the future that ranks equally with the 2047 Notes, including the Company’s 2045 Notes and (iv) subordinate in right of payment to any of the Company’s future senior debt. In addition, the 2047 Notes are structurally subordinated to all existing and future indebtedness, liabilities and other obligations of the Company’s subsidiaries including the Company’s margin borrowing facility. The 2047 Notes do not require the maintenance of any financial ratios or specified levels of net worth or liquidity, and do not contain provisions that would afford holders of the 2047 Notes protection in the event of a sudden and dramatic decline in the Company’s credit quality resulting from any highly leveraged transaction, reorganization, restructuring, merger or similar transaction involving the Company that may adversely affect holders. The 2047 Notes do not restrict the Company in any way, now or in the future, from incurring additional indebtedness, including senior indebtedness that would rank senior in right of payment to the 2047 Notes. There is no right of acceleration of maturity of the 2047 Notes in the case of default in the payment of principal, premium, if any, or interest on the 2047 Notes or in the performance of any other obligation of the Company under the notes or if the Company defaults on any other debt securities. Holders may accelerate payment of indebtedness on the 2047 Notes only upon the Company’s bankruptcy, insolvency or reorganization.

("GIGI"), an indirect wholly owned subsidiary of the Company, became a subordinated co-obligor with respect to the 2045 Notes and the 2047 Notes with the same obligations and duties as the Company under the Indenture (including the due and punctual performance and observance of all of the covenants and conditions to be performed by the Company, including, without limitation, the obligation to pay the principal of, and interest on, the Notes of either series when due whether at maturity, by acceleration, redemption or otherwise), and with the same rights, benefits and privileges of the Company thereunder. Notwithstanding the foregoing, GIGI's obligations (including the obligation to pay the principal of and interest in respect of the Notes of any series) are subject to subordination to all monetary obligations or liabilities of GIGI owing to Global Indemnity Reinsurance, Ltd., a wholly owned subsidiary of the Company, and/or any other regulated reinsurance or insurance company that is a direct or indirect subsidiary of the Company, in addition to indebtedness of GIGI for borrowed money. If the Company pays any amount with respect to the subordinated note obligations, the Company is entitled to be reimbursed by GIGI within 10 business days after a demand is made to GIGI by the Company. In consideration for becoming a subordinated co-obligor on the subordinated notes, GIGI received a promissory note from the Company with a principal amount of $230 million due April 15, 2047 that has since been assigned to an affiliate. This promissory note is eliminated in consolidation.

Equity [Abstract]
Shareholders' Equity	12. Shareholders’ Equity On November 7, 2016, Global Indemnity plc, an Irish public limited company, and Global Indemnity Limited, a Cayman Islands exempted company, completed the previously disclosed scheme of arrangement under Irish law (the “Scheme of Arrangement”) that effected a transaction (the “Redomestication”) that resulted in the shareholders of Global Indemnity plc becoming shareholders of Global Indemnity Limited, and Global Indemnity plc becoming a subsidiary of Global Indemnity Limited until it was liquidated in 2017. In accordance with the terms of the Scheme of Arrangement, the following steps occurred effectively simultaneously on November 7, 2016: 1. 13,463,864 shares of Global Indemnity plc A ordinary shares, par value $0.0001 per share, which represent all of the existing A ordinary shares excluding the treasury shares held by Global Indemnity plc and A shares held by Global Indemnity Limited, and 4,133,366 Global Indemnity plc B ordinary shares, par value $0.0001 per share, (together, the “Global Indemnity plc ordinary shares”) were cancelled. The treasury shares of Global Indemnity plc were not subject to the scheme. The carrying value of the Global Indemnity plc treasury shares, $103.2 million, were offset against the Additional Paid-in Capital account of Global Indemnity Limited, according to the Company’s policy regarding the treatment of treasury shares; 2. the reserves created on the cancellation of the Global Indemnity plc ordinary shares were used to issue 17,597,230 Global Indemnity plc ordinary shares to Global Indemnity Limited; and 3. in return for such issuance of new Global Indemnity plc ordinary shares to Global Indemnity Limited, Global Indemnity Limited issued 13,463,864 A ordinary shares, par value $0.0001 per share, and 4,133,366 Global Indemnity Limited B ordinary shares, par value $0.0001 per share (together the “Global Indemnity Limited ordinary shares”), to the former stockholders of Global Indemnity plc. Each shareholder received one Global Indemnity Limited A ordinary share for each Global Indemnity plc A ordinary share owned by such shareholder prior to the Scheme of Arrangement and one Global Indemnity Limited B ordinary share for each Global Indemnity plc B ordinary share owned by such shareholder prior to the Scheme of Arrangement. Prior to the Redomestication, the Global Indemnity plc A ordinary shares were listed on the Nasdaq Global Select Market (“Nasdaq”) under the symbol “GBLI” and registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In connection with the Redomestication, Global Indemnity plc requested that Nasdaq file with the U.S. Securities and Exchange Commission (the “SEC”) an application to strike the Global Indemnity plc A ordinary shares from listing on Nasdaq and the Global Indemnity plc A ordinary shares from registration under the Exchange Act. The Global Indemnity Limited ordinary shares are deemed registered under the Exchange Act. The Global Indemnity Limited A ordinary shares began trading on Nasdaq under the symbol “GBLI,” the same symbol under which the Global Indemnity plc ordinary shares previously traded, at the opening of Nasdaq on November 7, 2016. Dividend Restriction The ability of Global Indemnity Limited to pay dividends is subject to Cayman Island regulations. Under Cayman Islands law, dividends and distributions may only be made from distributable reserves or from amounts standing to the credit of the Company’s share premium account, together with any reserve established by the revaluation of the Company’s asset, subject to the ability of the Company to meet its obligations in the ordinary course as they fall due. Distributable reserves represents the accumulated realized profits and losses of Global Indemnity Limited on a standalone basis, which is $215.1 million as of December 31, 2018. Share premium represents the excess of the consideration paid upon the initial issuance of any share over the par value. As of December 31, 2018, share premium was $438.2 million. Reserves established by the revaluation of the Company’s asset were ($21.2) million as of December 31, 2018. As of December 31, 2018, the maximum dividends and distributions allowable under Cayman Island law is $632.1 million. Since the Company is a holding company and has no direct operations, its ability to pay dividends depends, in part, on the ability of its subsidiaries to pay dividends. Global Indemnity Reinsurance and the U.S. insurance subsidiaries are subject to significant regulatory restrictions limiting their ability to declare and pay dividends. See Note 18 for additional information regarding dividend limitations imposed on Global Indemnity Reinsurance and the U.S. insurance subsidiaries. Dividend Program During the fourth quarter of 2017, Global Indemnity announced the adoption of a dividend program. Although subject to the absolute discretion of the Board of Directors and factors, conditions, and prospects as such may exist from time to time when the Board of Directors considers the advisability of declaring a quarterly dividend, the Company currently anticipates a dividend rate of $0.25 per share per quarter ($1.00 per share per year). Dividends Dividend payments of $0.25 per ordinary share per quarter were paid as follows: Approval Date Record Date Payment Date Total Dividends Paid ($ in thousands) March 4, 2018 March 21, 2018 March 29, 2018 $ 3,499 June 3, 2018 June 22, 2018 June 29, 2018 3,502 September 16, 2018 September 27, 2018 October 1, 2018 3,504 December 2, 2018 December 24, 2018 December 31, 2018 3,506 Various (1) Various Various 16 Total $ 14,027 (1) Represents dividends paid upon the vesting of shares. As of December 31, 2018, accrued dividends on unvested shares, which were included in other liabilities on the consolidated balance sheets, were $0.2 million. Repurchases and Redemptions of the Company’s Ordinary Shares The Company allows employees to surrender A ordinary shares as payment for the tax liability incurred upon the vesting of restricted stock that was issued under the Company’s share incentive plan in effect at the time of issuance. During 2018, 2017, and 2016, the Company purchased an aggregate of 45,233, 29,551 and 28,099, respectively, of surrendered A ordinary shares from its employees for $1.8 million, $1.2 million and $0.8 million, respectively. All shares purchased from employees by the Company are held as treasury stock and recorded at cost until formally retired by the company. In 2015, the Company entered into a redemption agreement with certain affiliates of the Fox Paine Funds to redeem 8,260,870 of its ordinary shares. In conjunction with the 2015 redemption, the Company acquired rights, expiring year end 2019, to redeem an additional 3,397,031 ordinary shares for $78.1 million, which amount was subject to an annual 3% increase. On December 29, 2017, Global Indemnity acquired 3,397,031 of its A ordinary shares for approximately $83.0 million in the aggregate (approximately $24.44 per share) from former investors in the Fox Paine Funds.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies Legal Proceedings 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. The Company anticipates that, similar to the rest of the insurance and reinsurance industry, it will continue to be subject to litigation and arbitration proceedings in the ordinary course of business. Commitments In 2014, the Company entered into a $50 million commitment to purchase an alternative investment vehicle which is comprised of European non-performing loans.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation Plans	15. Share-Based Compensation Plans Effective January 1, 2017, the Company adopted new accounting guidance which changed several aspects of the accounting for share-based payment transactions. Under the new guidance, all excess tax benefits and tax deficiencies associated with share-based payment awards are required to be recognized as an income tax benefit or expense in net income with the corresponding cash flows recognized as an operating activity in the Consolidated Statement of Cash Flow as opposed to being reported separately as a financing activity. Excess tax benefits and deficiencies are no longer recognized in additional paid-in-capital. The new guidance removes the requirement to delay recognition of any excess tax benefit when there is no current taxes payable to which the benefit would be applied. The new guidance also allows an employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur, rather than estimating forfeitures upon issuance of the award. Upon adoption of this new accounting guidance, the Company elected to retain its policy of accruing the compensation cost based on the number of awards that are expected to vest. The adoption of this accounting guidance did not result in any cumulative adjustment or restatement. The provisions of this new guidance were adopted on a prospective basis and did not have a material impact on the Company’s financial position, results of operations or cash flows. The fair value method of accounting recognizes share-based compensation to employees and non-employee directors in the consolidated statements of operations using the grant-date fair value of the stock options and other equity-based compensation expensed over the requisite service and vesting period. For the purpose of determining the fair value of stock option awards, the Company uses the Black-Scholes option-pricing model. An estimation of forfeitures is required when recognizing compensation expense which is then adjusted over the requisite service period should actual forfeitures differ from such estimates. Changes in estimated forfeitures are recognized through a cumulative adjustment to compensation in the period of change. Prior to January 1, 2017, the prescribed accounting guidance required tax benefits relating to excess stock-based compensation deductions to be presented in the consolidated statements of cash flows as financing cash inflows. The tax benefit resulting from stock-based compensation deductions in excess of amounts reported for financial reporting purposes was $0.1 million for the year ended December 31, 2016. Share Incentive Plan On June 13, 2018, the Company’s Shareholders approved the Global Indemnity Limited 2018 Share Incentive Plan (“the 2018 Plan”). The purpose of the 2018 Plan is to provide the Company a competitive advantage in attracting, retaining, and motivating officers, employees, consultants and non-employee directors, and to provide the Company with a share plan providing incentives linked to the financial results of the Company’s business and increases in shareholder value. Under the 2018 Plan, the Company may issue up to 2.5 million A ordinary shares pursuant to awards granted under the Plan. The 2018 Plan replaced the Global Indemnity Limited Share Incentive Plan, effective since February 2014, which was set to expire pursuant to its terms on February 9, 2019. Options Award activity for stock options granted under the Plan and the weighted average exercise price per share are summarized as follows: Time-Based Options Performance- Based Options Total Options Weighted Average Exercise Price Per Share Options outstanding at January 1, 2016 300,000 500,000 800,000 $ 25.94 Options issued — - - — Options forfeited — (200,000 ) (200,000 ) 28.37 Options exercised — — — — Options expired — — — — Options purchased by the Company — — — — Options outstanding at December 31, 2016 300,000 300,000 600,000 25.13 Options issued — — — — Options forfeited — — — — Options exercised — — — — Options expired — — — — Options purchased by the Company — — — — Options outstanding at December 31, 2017 300,000 300,000 (1) 600,000 25.13 Options issued 300,000 — 300,000 50.00 Options forfeited — (100,000 ) (100,000 ) 38.43 Options exercised — — — — Options expired — — — — Options purchased by the Company — — — — Options outstanding at December 31, 2018 600,000 200,000 800,000 $ 35.06 Options exercisable at December 31, 2018 400,000 — 400,000 $ 25.90 (1) In 2014, 300,000 options were granted. On March 6, 2018, the existing vesting provisions of these options were eliminated and replaced with new vesting provisions related to return on equity targets for 2018, 2019, and 2020 (“Bonus Years”). 100,000 options were related to the 2018 Bonus Year. Return on equity targets for the 2018 bonus year were not met and therefore, these 100,000 options have been forfeited. 200,000 options remain outstanding but are not yet exercisable. 100,000 options are related to return on equity targets for the 2019 bonus year. These options are subject to remeasurement of 2019 bonus year results after the third full calendar year following the bonus year. 100,000 options are related to return on equity targets for the 2020 bonus year. These options are subject to remeasurement of 2020 bonus year results after the third full calendar year following the bonus year. During the year ended December 31, 2018, the Company awarded 300,000 options with a strike price of $50.00. There were no stock options issued in 2017 or 2016. The Company recorded $0.3 million, ($0.4) million, and $0.3 million of compensation expense for stock options outstanding under the Plan during the years ended December 31, 2018, 2017, and 2016, respectively. The Company did not receive any proceeds from the exercise of options during 2018, 2017 or 2016 under the Plan. Compensation expense related to options outstanding under the Plan is anticipated to be $1.3 million and $0.7 million during the years ended December 31, 2019 and 2020, respectively. Option intrinsic values, which are the differences between the fair value of $36.23 at December 31, 2018 and the strike price of the option, are as follows: Number of Shares Weighted Average Strike Price Intrinsic Value Outstanding 800,000 35.06 5.5 million Exercisable 400,000 25.90 5.5 million Exercised (1) — — — (1) The intrinsic value of the exercised options is the difference between the fair market value at time of exercise and the strike price of the option.

Earnings Per Share [Abstract]
Earnings Per Share	17. 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. The following table sets forth the computation of basic and diluted earnings per share. Years Ended December 31, (Dollars in thousands, except share and per share data) 2018 2017 2016 Net income (loss) $ (56,696 ) $ (9,551 ) $ 49,868 Basic earnings per share: Weighted average shares outstanding - basic 14,088,883 17,308,663 17,246,717 Net income (loss) per share $ (4.02 ) $ (0.55 ) $ 2.89 Diluted earnings per share: Weighted average shares outstanding – diluted (1) 14,088,883 17,308,663 17,547,061 Net income (loss) per share $ (4.02 ) $ (0.55 ) $ 2.84 (1) For the years ended December 31, 2018 and 2017, “weighted average shares outstanding – basic” was used to calculate “diluted earnings per share” due to a net loss for the period. A reconciliation of weighted average shares for basic earnings per share to weighted average shares for diluted earnings per share is as follows: Years Ended December 31, 2018 2017 2016 Weighted average shares for basic earnings per share 14,088,883 17,308,663 17,246,717 Non-vested restricted stock — — 187,526 Options — — 112,818 Weighted average shares for diluted earnings per share 14,088,883 17,308,663 17,547,061 If the Company had not incurred a loss in the years ended December 31, 2018 and 2017, 14,325,276 and 17,680,209 weighted average shares, respectively, would have been used to compute the diluted loss per share calculations. In addition to the basic shares, weighted average shares for the diluted calculations would have included 76,568 and 157,441 shares of non-vested restricted stock, respectively, and 159,825 and 214,105 share equivalents for options, respectively. The weighted average shares outstanding used to determine dilutive earnings per share for the years ended December 31, 2018 and 2016 do not include 500,000 and 300,000 options, respectively, which were deemed to be anti-dilutive. The year ended December 31, 2017 did not have any options that were deemed to be anti-dilutive.

Insurance [Abstract]
Statutory Financial Information	18. Statutory Financial Information GAAP differs in certain respects from Statutory Accounting Principles (“SAP”) as prescribed or permitted by the various U.S. state insurance departments. The principal differences between SAP and GAAP are as follows: • Under SAP, investments in debt securities are primarily carried at amortized cost, while under GAAP the Company records its debt securities at estimated fair value. • Under SAP, policy acquisition costs, such as commissions, premium taxes, fees and other costs of underwriting policies are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis over the period covered by the policy. • Under SAP, certain assets designated as "Non-admitted assets" (such as prepaid expenses) are charged against surplus. • Under SAP, net deferred income tax assets are admitted following the application of specified criteria, with the resulting admitted deferred tax amount being credited directly to surplus. • Under SAP, certain premium receivables are non-admitted and are charged against surplus based upon aging criteria. • Under SAP, the costs and related receivables for guaranty funds and other assessments are recorded based on management's estimate of the ultimate liability and related receivable settlement, while under GAAP such costs are accrued when the liability is probable and reasonably estimable and the related receivable amount is based on future premium collections or policy surcharges from in-force policies. • Under SAP, unpaid losses and loss adjustment expenses and unearned premiums are reported net of the effects of reinsurance transactions, whereas under GAAP, unpaid losses and loss adjustment expenses and unearned premiums are reported gross of reinsurance. • Under SAP, a provision for reinsurance is charged to surplus based on the authorized status of reinsurers, available collateral, and certain aging criteria, whereas under GAAP, an allowance for uncollectible reinsurance is established based on management’s best estimate of the collectability of reinsurance receivables. • Under SAP, the tax impact of the Tax Cuts and Jobs Act enacted on December 22, 2017 is recorded through surplus, whereas under GAAP, the tax impact is recorded in the Consolidated Statements of Operations. The National Association of Insurance Commissioners (“NAIC”) issues model laws and regulations, many of which have been adopted by state insurance regulators, relating to: (a) risk-based capital ("RBC") standards; (b) codification of insurance accounting principles; (c) investment restrictions; and (d) restrictions on the ability of insurance companies to pay dividends. The Company’s U.S. insurance subsidiaries are required by law to maintain certain minimum surplus on a statutory basis, and are subject to regulations under which payment of a dividend from statutory surplus is restricted and may require prior approval of regulatory authorities. Applying the current regulatory restrictions as of December 31, 2018, the maximum amount of distributions that could be paid in 2019 by the United National insurance companies and the Penn-America insurance companies under applicable laws and regulations without regulatory approval is approximately $10.6 million and $6.5 million, respectively. The Penn-America insurance companies limitation includes $2.1 million that would be distributed to United National Insurance Company or its subsidiary Penn Independent Corporation based on the December 31, 2018 ownership percentages. American Reliable is unable to pay a distribution in 2019 without regulatory approval. During 2018, the United National Insurance Company declared and paid dividends of $20.0 million. Penn-America Insurance Company and American Reliable did not declare or pay any dividends in 2018. The NAIC's RBC model provides a tool for insurance regulators to determine the levels of statutory capital and surplus an insurer must maintain in relation to its insurance and investment risks, as well as its reinsurance exposures, to assess the potential need for regulatory attention. The model provides four levels of regulatory attention, varying with the ratio of an insurance company's total adjusted capital to its authorized control level RBC ("ACLRBC"). If a company’s total adjusted capital is: (a) less than or equal to 200%, but greater than 150% of its ACLRBC (the "Company Action Level"), the company must submit a comprehensive plan to the regulatory authority proposing corrective actions aimed at improving its capital position; (b) less than or equal to 150%, but greater than 100% of its ACLRBC (the "Regulatory Action Level"), the regulatory authority will perform a special examination of the company and issue an order specifying the corrective actions that must be followed; (c) less than or equal to 100%, but greater than 70% of its ACLRBC (the "Authorized Control Level"), the regulatory authority may take any action it deems necessary, including placing the company under regulatory control; and (d) less than or equal to 70% of its ACLRBC (the "Mandatory Control Level"), the regulatory authority must place the company under its control. Based on the standards currently adopted, the Company reported in its 2018 statutory filings that the capital and surplus of the U.S. insurance companies are above the prescribed Company Action Level RBC requirements. The following is selected information for the Company’s U.S. insurance companies, net of intercompany eliminations, where applicable, as determined in accordance with SAP: Years Ended December 31, (Dollars in thousands) 2018 2017 2016 Statutory capital and surplus, as of end of period $ 225,645 $ 274,586 $ 323,144 Statutory net income (loss) (52,036 ) (19,019 ) 35,618 Global Indemnity Reinsurance must also prepare annual statutory financial statements. The Bermuda Insurance Act 1978 (the “Insurance Act”) prescribes rules for the preparation and substance of these statutory financial statements which include, in statutory form, a balance sheet, an income statement, a statement of capital and surplus and notes thereto. The statutory financial statements are not prepared in accordance with GAAP or SAP and are distinct from the financial statements prepared for presentation to Global Indemnity Reinsurance's shareholders and under the Bermuda Companies Act 1981 (the “Companies Act”), which financial statements will be prepared in accordance with GAAP. The principal differences between statutory financial statements prepared under the Insurance Act and GAAP are as follows: • Under the Insurance Act, policy acquisition costs, such as commissions, premium taxes, fees and other costs of underwriting policies are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis over the period covered by the policy. • Under the Insurance Act, prepaid expenses and intangible assets are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis. • Under the Insurance Act, unpaid losses and loss adjustment expenses and unearned premiums are reported net of the effects of reinsurance transactions, whereas under GAAP, unpaid losses and loss adjustment expenses and unearned premiums are reported gross of reinsurance. Under the Companies Act, Global Indemnity Reinsurance may only declare or pay a dividend if it has no reasonable grounds for believing that it is, or would after the payment be, unable to pay its liabilities as they become due, or if the realizable value of its assets would not be less than the aggregate of its liabilities and its issued share capital and share premium accounts. Global Indemnity Reinsurance is also prohibited, without the approval of the BMA, from reducing by 15% or more its total statutory capital or 25% or more of its total statutory capital and surplus as set out in its previous year’s statutory financial statements, and any application for such approval must include such information as the BMA may require. Based upon the total statutory capital plus the statutory surplus as set out in its 2018 statutory financial statements that will be filed in 2019, Global Indemnity Reinsurance could pay a dividend of up to $223.9 million without requesting BMA approval. Global Indemnity Reinsurance is dependent on receiving distributions from its subsidiaries in order to pay the full dividend in cash. In 2018, Global Indemnity Reinsurance declared and paid a dividend of $50.0 million to its parent, Global Indemnity. In addition, Global Indemnity Reinsurance paid a dividend of $20.0 million in 2018, which was previously declared in 2017, to Global Indemnity. The following is selected information for Global Indemnity Reinsurance, net of intercompany eliminations, where applicable, as determined in accordance with the Bermuda Insurance Act 1978: Years Ended December 31, (Dollars in thousands) 2018 2017 2016 Statutory capital and surplus, as of end of period $ 835,620 $ 908,433 $ 838,923 Statutory net income (3,972 ) 29,647 32,768

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	22. New Accounting Pronouncements Accounting Standards Adopted in 2018 In July, 2018, the FASB issued new accounting guidance that affected a wide variety of topics in the Codification. The amendments in this update represent changes to clarify, correct errors in, or make minor improvements to the Codification. This amendment is meant to make the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarification. Some of the amendments in this guidance are effective immediately with the remainder effective for annual periods beginning after December 31, 2018. The adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. In February, 2018, the FASB issued new accounting guidance which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA. The amendments in this Update also require certain disclosures related to stranded tax effects. The guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company early adopted the provisions of this new guidance on a retrospective basis as of January 1, 2018 and made an election to reclassify, in its entirety, all stranded tax effects related to TCJA. As a result, the Company recorded a cumulative effect adjustment of $0.1 million which was reclassified from accumulated other comprehensive income to retained earnings. The adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. In May, 2017, the FASB issued updated accounting guidance which clarified 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. The Company adopted this guidance during the first quarter of 2018. The provisions of this guidance were adopted on a prospective basis. As a result of adopting this guidance, stock based compensation decreased by less than $0.1 million during the year ended December 31, 2018. The adjustment was due to the Company entering into an Employment Agreement with its Chief Executive Officer which modified the vesting schedule on 300,000 options issued in 2014. The Company did not record a cumulative effect adjustment to shareholders’ equity as a result of adopting this guidance and the adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. In October, 2016, the FASB issued new accounting guidance regarding intra-entity transfers of assets other than inventory. Prior to adoption, the tax effects of intra-entity asset transfers (intercompany sales) were deferred until the transferred asset was sold to a third party or otherwise recovered through use. This is an exception to the principle in ASC 740, Income Taxes, that generally requires comprehensive recognition of current and deferred income taxes. The new guidance eliminates the exception for all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. Upon adoption on January 1, 2018, the Company applied the provisions of this guidance on a modified retrospective basis resulting in a cumulative-effect adjustment which increased retained earnings by $0.2 million. The adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. In August, 2016, the FASB issued new accounting guidance regarding the classification of certain cash receipts and cash payments within the statements of cash flows. The new guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This guidance is effective for public business entities for fiscal periods beginning after December 15, 2017, and interim periods within those fiscal years. Upon adoption on January 1, 2018, the Company made an accounting policy election to use the cumulative earnings approach for presenting distributions received from equity method investees. Under this approach, distributions up to the amount of cumulative equity in earnings recognized will be treated as returns on investment and presented in operating activities and those in excess of that amount will be treated as returns of investment and presented in the investing section. Prior to adoption, all distributions received from equity method investees were presented in the investing section of the consolidated statements of cash flows. The other cash flow issues addressed by the new guidance did not impact the Company. The provisions of this accounting guidance were adopted on a retrospective basis. The adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. In January, 2016, the FASB issued new accounting guidance surrounding the accounting for financial instruments. The new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. In particular, the guidance requires equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income. It also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. This guidance is effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Upon adoption on January 1, 2018, the Company recorded a cumulative effect adjustment, net of tax, of $10.0 million which reduced accumulated other comprehensive income and increased retained earnings. During the year ended December 31, 2018, net realized investment gains (losses) included a loss of $22.0 million related to the change in the fair value of equity investments in accordance with this new accounting guidance. In May, 2014, the FASB issued new accounting guidance regarding the recognition of revenue from customers arising from the transfer of goods and services. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted the standard and all related amendments using the modified retrospective method. Long and short duration insurance contracts, which comprise the majority of the Company’s revenues, are excluded from this accounting guidance. As such, revenue within the scope of the new guidance primarily includes fee income. The adoption of this new accounting guidance did not have a material impact to the Company’s financial condition, results of operation, or cash flows. There were no material changes in the timing or measurement of revenues based upon the guidance. As a result, there is no cumulative effect on retained earnings. Recently Issued Accounting Guidance Not Yet Adopted In August, 2018, the FASB issued new accounting guidance which removed, modified, and added certain disclosures related to Topic 820, Fair Value. This guidance is effective for all fiscal years beginning after December 15, 2019 including interim periods within those fiscal years. The Company does not expect the new guidance to have a material impact on its financial condition, results of operations, or cash flows. In June, 2018, the FASB issued new accounting guidance which expanded the scope of Accounting Standards Codification (“ASC”) Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. This guidance is effective for fiscal years beginning after December 15, 2018 including interim periods. The Company does not anticipate the new guidance having 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 amortization 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 does not anticipate the new guidance having a material impact 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 June, 2016, the FASB issued new accounting guidance addressing the measurement of credit losses on financial instruments. For assets held at amortized cost basis, the new guidance replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of information for credit loss estimates. For available for sale debt securities, credit losses should be measured similar to current GAAP; however, the new guidance requires that credit losses be presented as an allowance rather than as a write-down and allows for the reversal of credit losses in the current period net income. This guidance is effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early application of this new guidance is permitted as of the fiscal years beginning after December 15, 2018 including interim periods within those fiscal years. This guidance will be applied using a modified-retrospective approach through a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is still evaluating the impact of this guidance on its financial condition, results of operations, and cash flows. In February, 2016, the FASB issued new accounting guidance regarding leases. The new guidance increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. In July, 2018, additional accounting guidance was issued which provided entities with an additional and optional transition method when adopting this new standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative effect adjustment to the opening balance sheet of retained earnings. The lease guidance is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company plans to adopt this new accounting guidance on January 1, 2019 using the optional transition method. The Company will elect the package of practical expedients permitted under the transition guidance within the new standard. In addition, the Company will elect the hindsight practical expedient to determine the lease term for existing leases. The

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 primarily 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, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. The Company’s Reinsurance Operations consist solely of the operations of its Bermuda-based wholly-owned subsidiary, 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 The consolidated financial statements 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.
Intercompany Balances and Transactions	On January 1, 2018, the Company adopted new accounting guidance which requires equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income. Upon adoption, the Company recorded a cumulative effect adjustment, net of tax, of $10.0 million which reduced accumulated other comprehensive income and increased retained earnings. During the year ended December 31, 2018, net realized investment gains (losses) included a loss of $22.0 million related to the change in the fair value of equity investments in accordance with this new accounting guidance. In addition, under the new guidance, equity investments, are no longer classified into different categories as either trading or available for sale. Prior to the adoption of this new guidance, equity securities were previously classified as available for sale. On January 1, 2018, the Company adopted new accounting guidance regarding the classification of certain cash receipts and cash payments within the statement of cash flows. Upon adoption, the Company made a policy election to use the cumulative earnings approach for presenting distributions received from equity method investees. Under this approach, distributions up to the amount of cumulative equity in earnings recognized will be treated as returns on investment and presented in operating activities and those in excess of that amount will be treated as returns of investment and presented in the investing section. Prior to adoption, all distributions received from equity method investees were presented in the investing section of the consolidated statements of cash flows. The provisions of this accounting guidance were adopted on a retrospective basis. As a result, the consolidated statement of cash flows for the years ended December 31, 2017 and 2016 that was included in the Form 10-K for the years ended December 31, 2017 and 2016 was restated. For the years ended December 31, 2017 and 2016, net cash flows from operating activities was increased by $4.7 million and $5.2 million, respectively, and net cash flows from investing activities was reduced by $4.7 million and $5.2 million, respectively. 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	Investments The Company’s investments in fixed maturities, which are classified as available for sale, and equity securities are carried at their fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair values of the Company's fixed maturities and equity securities are determined on the basis of quoted market prices where available. If quoted market prices are not available, the Company uses third party pricing services to assist in determining fair value. In many instances, these services examine the pricing of similar instruments to estimate fair value. The Company purchases bonds with the expectation of holding them to their maturity; however, changes to the portfolio are sometimes required to assure it is appropriately matched to liabilities. In addition, changes in financial market conditions and tax considerations may cause the Company to sell an investment before it matures. The difference between amortized cost and fair value of the Company’s fixed maturity portfolio, net of the effect of deferred income taxes, is reflected in accumulated other comprehensive income in shareholders’ equity and, accordingly, has no effect on net income other than for the credit loss component of impairments deemed to be other than temporary. Equity securities are measured at fair value with the changes in fair value recognized in net income. For investments in limited liability companies and limited partnerships where the ownership interest is less than 3%, the Company carries these investments at fair value, and the change in the difference between cost and the fair value of the partnership interests, net of the effect of deferred income taxes, is reflected in accumulated other comprehensive income in shareholders' equity and, accordingly, has no effect on net income other than for impairments deemed to be other than temporary. 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 or limited partnership requires that its cost basis be updated to account for the income or loss earned on the investment. The income or loss associated with the limited liability companies or limited partnerships is reflected in the consolidated statements of operations, and the adjusted cost basis approximates fair value. The Company’s investments in other invested assets were valued at $50.8 million and $77.8 million as of December 31, 2018 and 2017, respectively. These amounts relate to investments in limited liability companies and limited partnerships. The Company does not have access to daily valuations, therefore; the estimated fair value of the limited liability companies and limited partnerships are based on net asset value as a practical expedient for the limited liability companies and limited partnerships. Net realized gains and losses on investments are determined based on the first-in, first-out method. 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. Prior to the implementation of new accounting guidance on January 1, 2018, management carefully reviewed all equities securities with unrealized losses to determine if a security should be impaired and further focuses on securities that had either: (1) persisted with unrealized losses for more than twelve consecutive months or (2) the value of the investment had been 20% or more below cost for six continuous months or more. On January 1, 2018, the Company adopted new accounting guidance which requires equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income. 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. For an analysis of other than temporary losses that were recorded for the years ended December 31, 2018, 2017, and 2016, please see Note 4 below.
Variable Interest Entities	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 two VIEs 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.
Cash and Cash Equivalents	Cash and Cash Equivalents For the purpose of the statements of cash flows, the Company considers all liquid instruments with an original maturity of three months or less to be cash equivalents. The Company has a cash management program that provides for the investment of excess cash balances primarily in short-term money market instruments. Generally, bank balances exceed federally insured limits. The carrying amount of cash and cash equivalents approximates fair value. At December 31, 2018 and 2017, the Company had approximately $77.4 million and $67.1 million, respectively, of cash and cash equivalents that was invested in a diversified portfolio of high quality short-term debt securities.
Valuation of Premium Receivable	Valuation of Premium Receivable The Company evaluates the collectability of premium receivable based on a combination of factors. In instances in which the Company is aware of a specific circumstance where a party may be unable to meet its financial obligations to the Company, a specific allowance for bad debts against amounts due is recorded to reduce the net receivable to the amount reasonably believed by management to be collectible. For all remaining balances, allowances are recognized for bad debts based on the length of time the receivables are past due. The allowance for bad debts was $2.3 million and $2.2 million as of December 31, 2018 and 2017, respectively.
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company tests for impairment of goodwill at least annually and more frequently as circumstances warrant in accordance with applicable accounting guidance. Accounting guidance allows for the testing of goodwill for impairment using both qualitative and quantitative factors. Impairment of goodwill is recognized only if the carrying amount of the reporting unit, including goodwill, exceeds the fair value of the reporting unit. The amount of the impairment loss would be equal to the excess carrying value of the goodwill over the implied fair value of the reporting unit goodwill. Based on the qualitative assessment performed, t of as of December 31, 2018. Impairment of intangible assets with an indefinite at least annually and more frequently as circumstances warrant here were no impairments Intangible assets that are not deemed to have an indefinite useful life are amortized over their estimated useful lives. The carrying amounts of definite lived intangible assets are regularly reviewed for indicators of impairment in accordance with applicable accounting guidance. Impairment is recognized only if the carrying amount of the intangible asset is in excess of its undiscounted projected cash flows. The impairment is measured as the difference between the carrying amount and the estimated fair value of the asset. As of December 31, 2018, there were no triggering events that occurred during the year that would result in an impairment of definite lived intangible assets. See Note 7 for additional information on goodwill and intangible assets.
Reinsurance	Reinsurance In the normal course of business, the Company seeks to reduce the loss that may arise from events that cause unfavorable underwriting results by reinsuring certain levels of risk from various areas of exposure with reinsurers. Amounts receivable from reinsurers are estimated in a manner consistent with the reinsured policy and the reinsurance contract. The Company regularly reviews the collectability of reinsurance receivables. An allowance for uncollectible reinsurance receivable is recognized based on the financial strength of the reinsurers and the length of time any balances are past due. Any changes in the allowance resulting from this review are included in net losses and loss adjustment expenses on the consolidated statements of operations during the period in which the determination is made. The allowance for uncollectible reinsurance was $8.0 million as of December 31, 2018 and 2017. The applicable accounting guidance requires that the reinsurer must assume significant insurance risk under the reinsured portions of the underlying insurance contracts and that there must be a reasonably possible chance that the reinsurer may realize a significant loss from the transaction. The Company has evaluated its reinsurance contracts and concluded that each contract qualifies for reinsurance accounting treatment pursuant to this guidance.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. The deferred tax asset balance is analyzed regularly by management. This assessment requires significant judgment and considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of carryforward periods, and tax planning strategies and/or actions. Management believes that it is more likely than not that the results of future operations can generate sufficient taxable income to realize the remaining deferred income tax assets, and accordingly, the Company has not established any valuation allowances.
Deferred Acquisition Costs	Deferred Acquisition Costs The costs of acquiring new and renewal insurance and reinsurance contracts include commissions, premium taxes and certain other costs that are directly related to the successful acquisition of new and renewal insurance and reinsurance contracts. The excess of the Company’s costs of acquiring new and renewal insurance and reinsurance contracts over the related ceding commissions earned from reinsurers is capitalized as deferred acquisition costs and amortized over the period in which the related premiums are earned. The amortization of deferred acquisition costs for the years ended December 31, 2018, 2017, and 2016 was $118.0 million, $109.0 million, and $114.3 million, respectively.
Premium Deficiency	Premium Deficiency A premium deficiency is recognized if the sum of expected loss and loss adjustment expenses and unamortized acquisition costs exceeds related unearned premium after consideration of investment income. This evaluation is done at a distribution and product line level in Insurance Operations and at a treaty level in Reinsurance Operations. Any future expected loss on the related unearned premium is recorded first by impairing the unamortized acquisition costs on the related unearned premium followed by an increase to loss and loss adjustment expense reserves on additional expected loss in excess of unamortized acquisition costs. No premium deficiency reserve existed as of December 31, 2018 or 2017.
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage its exposure to cash flow variability from interest rate risk. The derivative instruments are carried on the balance sheet at fair value and included in other assets and other liabilities. Changes in the fair value of the derivative instruments and the periodic net interest settlements under the derivatives instruments are recognized as net realized investment gains (losses) on the consolidated statements of operations. The Company accounts for the interest rate swaps as non-hedge instruments and 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 or losses in the consolidated statements of operations. The Company is ultimately responsible for the valuation of the interest rate swaps. To aid in determining the estimated fair value of the interest rate swaps, the Company relies on the forward interest rate curve and information obtained from a third party financial institution.
Margin Borrowing Facility	Margin Borrowing Facility The carrying amounts reported in the balance sheet represent the outstanding borrowings. The outstanding borrowings are due on demand; therefore, the cash receipts and cash payments related to the margin borrowing facility are shown net in the consolidated statements of cash flows.
Subordinated Notes	Subordinated Notes The carrying amounts reported in the balance sheet represent the outstanding balances, net of deferred issuance cost. See Note 11 for details.
Unpaid Losses and Loss Adjustment Expenses	Unpaid Losses and Loss Adjustment Expenses The liability for unpaid losses and loss adjustment expenses represents the Company’s best estimate of future amounts needed to pay losses and related settlement expenses with respect to events insured by the Company. This liability is based upon the accumulation of individual case estimates for losses reported prior to the close of the accounting period with respect to direct business, estimates received from ceding companies with respect to assumed reinsurance, and estimates of unreported losses. The process of establishing the liability for unpaid losses and loss adjustment is complex, requiring the use of informed actuarially based estimates and management’s judgment. In some cases, significant periods of time, up to several years or more, may elapse between the occurrence of an insured loss and the reporting of that loss to the Company. To establish this liability, the Company regularly reviews and updates the methods of making such estimates and establishing the resulting liabilities. Any resulting adjustments are recorded in consolidated statements of operations during the period in which the determination is made.
Retirement of Treasury Stock	Retirement of Treasury Stock Upon the formal retirement of treasury stock, the Company offsets the par value of the treasury stock that is being retired against Ordinary Shares and reflects any excess of cost over par value as a deduction from Additional Paid-in Capital.
Share Redemptions	Share Redemptions When shares are redeemed, the Company offsets the par value of the redeemed shares against Ordinary Shares and reflects any excess of cost over par value as a deduction from Retained Earnings.
Premiums	Premiums Premiums are recognized as revenue ratably over the term of the respective policies and treaties. Unearned premiums are computed on a pro rata basis to the day of expiration. Mandatory reinstatement premiums assessed on reinsurance policies are earned in the period of the loss event that gave rise to the reinstatement premiums.
Contingent Commissions	Contingent Commissions Certain professional general agencies of the Insurance Operations are paid special incentives, referred to as contingent commissions, when results of business produced by these agencies are more favorable than predetermined thresholds. Similarly, in some circumstances, companies that cede business to the Reinsurance Operations are paid profit commissions based on the profitability of the ceded portfolio. These commissions are charged to other underwriting expenses when incurred.
Share-Based Compensation	Share-Based Compensation The Company accounts for stock options and other equity based compensation using the modified prospective application of the fair value-based method permitted by the appropriate accounting guidance. See Note 15 for details.
Earnings per Share	Earnings per Share Basic earnings per share have been calculated by dividing net income available to common shareholders by the weighted-average ordinary shares outstanding. In periods of net income, diluted earnings per share have been calculated by dividing net income available to common shareholders by the sum of the weighted-average ordinary shares outstanding and the weighted-average common share equivalents outstanding, which include options and other equity awards. In periods of net loss, diluted earnings per share is the same as basic earnings per share. See Note 17 for details. Earnings per share have been computed using the weighted average number of ordinary shares and ordinary share equivalents outstanding during the period.
Foreign Currency	Foreign Currency The Company maintains investments and cash accounts in foreign currencies related to the operations of its business. At period-end, the Company re-measures non-U.S. currency financial assets to their current U.S. dollar equivalent. The resulting gain or loss for foreign denominated fixed maturity investments is reflected in accumulated other comprehensive income in shareholders’ equity; whereas, the gain or loss on foreign denominated cash accounts and equity securities is reflected in income during the period. Financial liabilities, if any, are generally adjusted within the reserving process. However, for known losses on claims to be paid in foreign currencies, the Company re-measures the liabilities to their current U.S. dollar equivalent each period end with the resulting gain or loss reflected in income during the period. Net transaction gains and losses, primarily comprised of re-measurement of known losses on claims to be paid in foreign currencies, were a loss
Other Income	Other Income On September 30, 2016, Diamond State Insurance Company sold all the outstanding shares of capital stock of one of its wholly owned subsidiaries, United National Specialty Insurance Company, to an unrelated party. Diamond State Insurance Company received a one-time payment of $18.7 million and recognized a pretax gain of $6.9 million which is reflected in other income in 2016. This transaction did not have an impact on the Company’s ongoing business operations. Subsequent to the sale, any business previously written by United National Specialty Insurance Company is being written by other companies within the Company’s U.S. Insurance Operations. In addition, in 2018, other income is primarily comprised of fee income and foreign exchange gains and losses. In 2017, other income is comprised of fee income on policies issued, commission income, accrued interest on the anticipated indemnification of unpaid loss and loss adjustment expense reserve, and foreign exchange gains and losses.
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. 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 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 terms and conditions sourced from commercial vendors. Bonds with similar characteristics are grouped into specific sectors. Both asset classes use standard inputs and utilize bid price or spread, quotes, benchmark yields, discount rates, market data feeds, and financial statements. • 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 benchmark 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, an integrated evaluation system is used. The pricing models incorporate trades, spreads, benchmark curves, market data feeds, new issue data, and trustee reports. • 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, various external analytical products are utilized and purchased from commercial vendors.
Statutory Income Tax Rates	The statutory income tax rate of each country is applied against the annual taxable income of each country to calculate the annual income tax expense
Tax Uncertainties	The Company applies a more-likely-than-not recognition threshold for all tax uncertainties whereby it only recognizes those tax benefits that have a greater than 50% likelihood of being sustained upon examination by the taxing authorities.
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.
Share-Based Compensation	The fair value method of accounting recognizes share-based compensation to employees and non-employee directors in the consolidated statements of operations using the grant-date fair value of the stock options and other equity-based compensation expensed over the requisite service and vesting period. For the purpose of determining the fair value of stock option awards, the Company uses the Black-Scholes option-pricing model. An estimation of forfeitures is required when recognizing compensation expense which is then adjusted over the requisite service period should actual forfeitures differ from such estimates. Changes in estimated forfeitures are recognized through a cumulative adjustment to compensation in the period of change. Prior to January 1, 2017, the prescribed accounting guidance required tax benefits relating to excess stock-based compensation deductions to be presented in the consolidated statements of cash flows as financing cash inflows. The tax benefit resulting from stock-based compensation deductions in excess of amounts reported for financial reporting purposes was $0.1 million for the year ended December 31, 2016.
Financial Information	GAAP differs in certain respects from Statutory Accounting Principles (“SAP”) as prescribed or permitted by the various U.S. state insurance departments. The principal differences between SAP and GAAP are as follows: • Under SAP, investments in debt securities are primarily carried at amortized cost, while under GAAP the Company records its debt securities at estimated fair value. • Under SAP, policy acquisition costs, such as commissions, premium taxes, fees and other costs of underwriting policies are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis over the period covered by the policy. • Under SAP, certain assets designated as "Non-admitted assets" (such as prepaid expenses) are charged against surplus. • Under SAP, net deferred income tax assets are admitted following the application of specified criteria, with the resulting admitted deferred tax amount being credited directly to surplus. • Under SAP, certain premium receivables are non-admitted and are charged against surplus based upon aging criteria. • Under SAP, the costs and related receivables for guaranty funds and other assessments are recorded based on management's estimate of the ultimate liability and related receivable settlement, while under GAAP such costs are accrued when the liability is probable and reasonably estimable and the related receivable amount is based on future premium collections or policy surcharges from in-force policies. • Under SAP, unpaid losses and loss adjustment expenses and unearned premiums are reported net of the effects of reinsurance transactions, whereas under GAAP, unpaid losses and loss adjustment expenses and unearned premiums are reported gross of reinsurance. • Under SAP, a provision for reinsurance is charged to surplus based on the authorized status of reinsurers, available collateral, and certain aging criteria, whereas under GAAP, an allowance for uncollectible reinsurance is established based on management’s best estimate of the collectability of reinsurance receivables. • Under SAP, the tax impact of the Tax Cuts and Jobs Act enacted on December 22, 2017 is recorded through surplus, whereas under GAAP, the tax impact is recorded in the Consolidated Statements of Operations.
Global Indemnity Reinsurance
Financial Information	Global Indemnity Reinsurance must also prepare annual statutory financial statements. The Bermuda Insurance Act 1978 (the “Insurance Act”) prescribes rules for the preparation and substance of these statutory financial statements which include, in statutory form, a balance sheet, an income statement, a statement of capital and surplus and notes thereto. The statutory financial statements are not prepared in accordance with GAAP or SAP and are distinct from the financial statements prepared for presentation to Global Indemnity Reinsurance's shareholders and under the Bermuda Companies Act 1981 (the “Companies Act”), which financial statements will be prepared in accordance with GAAP. The principal differences between statutory financial statements prepared under the Insurance Act and GAAP are as follows: • Under the Insurance Act, policy acquisition costs, such as commissions, premium taxes, fees and other costs of underwriting policies are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis over the period covered by the policy. • Under the Insurance Act, prepaid expenses and intangible assets are charged to current operations as incurred, while under GAAP such costs are deferred and amortized on a pro rata basis. • Under the Insurance Act, unpaid losses and loss adjustment expenses and unearned premiums are reported net of the effects of reinsurance transactions, whereas under GAAP, unpaid losses and loss adjustment expenses and unearned premiums are reported gross of reinsurance.

[2]	In 2014, 300,000 options were granted. On March 6, 2018, the existing vesting provisions of these options were eliminated and replaced with new vesting provisions related to return on equity targets for 2018, 2019, and 2020 (“Bonus Years”). 100,000 options were related to the 2018 Bonus Year. Return on equity targets for the 2018 bonus year were not met and therefore, these 100,000 options have been forfeited. 200,000 options remain outstanding but are not yet exercisable. 100,000 options are related to return on equity targets for the 2019 bonus year. These options are subject to remeasurement of 2019 bonus year results after the third full calendar year following the bonus year. 100,000 options are related to return on equity targets for the 2020 bonus year. These options are subject to remeasurement of 2020 bonus year results after the third full calendar year following the bonus year.
