The Company is also commercially domiciled in California, making it subject to California insurance holding company laws. These statutes require that each insurance company in the system register with the insurance department of its state of domicile and furnish information concerning the operations of companies within the holding company system that may materially affect the operations, management or financial condition of the insurers within the system and domiciled in that state. Segment Reporting The Company has a single operating segment, the property and casualty insurance business. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM reviews the Company’s consolidated net income as reported under GAAP, which is the primary measure of segment profit or loss. The CODM also reviews the individual measures and significant segment expenses that contribute to net income including gross written premiums, net earned premiums, losses and loss adjustment expenses, acquisition and underwriting expenses, and net investment income. The CODM reviews these measures, comparing them to prior periods and forecasted expectations, and makes resource allocation decisions based on the analysis. The significant segment expenses provided to the CODM are consistent with the categories shown in the Company’s Consolidated Statements of Income and Comprehensive Income and there are no other segment items used by the CODM. While the Company’s CODM also reviews the revenue streams attributable to individual products, operations are managed, resources are allocated, and financial performance is evaluated on a consolidated basis. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. The consolidated financial statements also include the accounts of Laulima, as Laulima is a variable interest entity (“VIE”) for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company’s consolidated financial statements include, but are not limited to, reserves for losses and loss adjustment expenses, reinsurance recoverables on unpaid losses, and the fair values of investments.
