Description of Business and Summary of Significant Accounting Policies	1. Description of Business and Summary of Significant Accounting Policies Description of Business Hippo Holdings Inc., referred to herein as “Hippo” or the “Company” is an insurance holding company incorporated in Delaware. Hippo has subsidiaries that provide property and casualty insurance products to both individuals and business customers. The Company’s headquarters are located in Palo Alto, California. Basis of Presentation and Consolidation The interim condensed consolidated financial statements and accompanying notes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and include the Company’s consolidated subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Certain information and disclosures normally included in condensed consolidated financial statements prepared in accordance with GAAP have been omitted accordingly. The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Interim results are not necessarily indicative of the results for a full year. Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include, but are not limited to, loss and loss adjustment expense (“LAE”) reserves, provision for commission slide and cancellations, reinsurance recoverable on paid and unpaid losses and LAE, the fair values of investments, stock-based awards, contingent consideration liabilities, acquired intangible assets, deferred tax assets and uncertain tax positions, and revenue recognition. The Company evaluates these estimates on an ongoing basis. These estimates are informed by experience and other assumptions that the Company believes are reasonable under the circumstances. Actual results may differ significantly from these estimates. Recent Accounting Pronouncements Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures. The ASU includes requirements that an entity disclose the title of the chief operating decision maker (CODM) and on an interim and annual basis, significant segment expenses and the composition of other segment items for each segment's reported profit. The standard also permits disclosure of additional measures of segment profit. This ASU is effective for public companies with annual periods beginning after December 15, 2023, and interim periods within annual period beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its disclosures. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This ASU is effective for public companies with annual periods beginning after December 15, 2024, with early adoption permitted.
