Principles of Consolidation and Basis of Presentation	1. Principles of Consolidation and Basis of Presentation Global Indemnity Group, LLC (“Global Indemnity” or "the Company"), a Delaware limited liability company formed on June 23, 2020, replaced Global Indemnity Limited, incorporated in the Cayman Islands as an exempted company with limited liability, as the ultimate parent company of the Global Indemnity group of companies as a result of a redomestication transaction completed on August 28, 2020. This transaction resulted in the redomestication of the Company to the United States. Global Indemnity Group, LLC’s class A common shares are publicly traded on the New York Stock Exchange under the ticker symbol GBLI. Global Indemnity Group, LLC’s predecessors have been publicly traded since 2003. See Note 2 below for additional information regarding the redomestication. During the fourth quarter of 2022, the Company decided to restructure its insurance operations in an effort to strengthen its market presence and enhance its focus on GBLI’s core Wholesale Commercial and InsurTech products. As a result, the Company will be exiting its four brokerage divisions: Professional Liability, Excess Casualty, Environmental, and Middle Market Property. The Company will cease writing new business and existing renewals will be placed in run-off for these four divisions. On August 8, 2022, the Company sold the renewal rights related to its Farm, Ranch & Stable business for policies written on or after August 8, 2022 to Everett Cash Mutual Insurance Company. During the 2nd quarter of 2022, the Company decided that Farm, Ranch & Stable would not be a core business and a decision was made to not allocate additional resources to this segment. Previously, on October 26, 2021, the Company sold the renewal rights related to its manufactured and dwelling homes business which were part of the Specialty Property segment. In 2021, the Company decided to cease writing certain Property Brokerage business which was part of the Commercial Specialty segment, as well as exit certain property and catastrophe lines within the Reinsurance Operations segment. In the fourth quarter of 2022, the Company also decided it will reduce writings within its Reinsurance Operations segment. Based on the decisions to exit or downsize these lines of business, the Company changed the way it manages and analyzes its operating results. The chief operating decision makers decided they will be reviewing the specific results of the Exited Lines in a separate segment. The chief operating decision makers also determined that the small amount of specialty property business that remained from the Specialty Property segment would be included as a product offering in the Commercial Specialty segment for purpose of reviewing results and allocating resources. Several smaller reinsurance treaties have also been reclassified from Reinsurance to Commercial Specialty. The Reinsurance Operations segment writes casualty treaties as well as individual excess policies. Accordingly, the Company has three reportable segments: Commercial Specialty, Reinsurance Operations, and Exited Lines. Management believes these segments allow users of the Company’s financial statements to better understand the Company's performance, better assess prospects for future net cash flows, and make more informed judgments about the Company as a whole. The segment results for the years ended December 31, 2021 and 2020 have been revised to reflect these changes. See Note 23 for additional information regarding segments. Global Indemnity Group, LLC is a holding company that is classified as a publicly traded partnership for U.S. federal income tax purposes and meets the qualifying income exception to maintain partnership status. Global Indemnity Group, LLC owns all shares of its direct and indirect subsidiaries, including those of its insurance companies: United National Insurance Company, Diamond State Insurance Company, Penn-America Insurance Company, Penn-Star Insurance Company, and Penn-Patriot Insurance Company. The insurance companies’ primary activity is providing insurance products across a distribution network that includes wholesale general agents, wholesale brokers, and retailers. The insurance companies manage the distribution of these products through two ongoing business segments: Commercial Specialty and Reinsurance Operations. Commercial Specialty offers specialty property and casualty products designed for GBLI's Wholesale Commercial and InsurTech product offerings. These product lines are offered primarily in the excess and surplus lines marketplace. Reinsurance Operations provides reinsurance and insurance solutions through brokers and primary writers including insurance and reinsurance companies. The company also has an Exited Lines segment that contains lines of business that are no longer being written or are in runoff, including specialty personal lines and property and casualty products such as manufactured home, dwelling, motorcycle, watercraft, certain homeowners business, certain business lines within property brokerage, property and catastrophe reinsurance treaties, and the farm, ranch and equine business. Collectively, the Company’s insurance subsidiaries are licensed in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. 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. The consolidated financial statements include the accounts of Global Indemnity Group, LLC and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain amounts not reported in prior year’s Consolidated Statements of Operations have been reported to conform to the presentation adopted in the current year. Specifically, the Company reported ceded written premiums and change in net unearned premiums in the current year presentation. This change had no effect on total revenues, total expenses, or net income (loss) reported for the prior years.
