Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Nature of Operations Universal Insurance Holdings, Inc. (“UVE”, and together with its wholly-owned subsidiaries, “the Company”) is a Delaware corporation incorporated in 1990. The Company is a vertically integrated insurance holding company performing all aspects of insurance underwriting, distribution and claims. Through its wholly-owned insurance company subsidiaries, Universal Property & Casualty Insurance Company (“UPCIC”) and American Platinum Property and Casualty Insurance Company (“APPCIC”, and together with UPCIC, the “Insurance Entities”), the Company is principally engaged in the property and casualty insurance business offered primarily through its network of independent agents. Risk from catastrophic losses is managed through the use of reinsurance agreements. The Company’s primary product is residential homeowners’ insurance offered in 19 states as of September 30, 2022, including Florida, which comprises the majority of the Company’s policies in force. See “—Note 5 (Insurance Operations)” for more information regarding the Company’s insurance operations. The Company generates revenues primarily from the collection of premiums and investment returns on funds invested on cash flows in excess of those retained and used for claims-paying obligations and insurance operations. Other significant sources of revenue include brokerage commissions collected from reinsurers on certain reinsurance programs placed on behalf of the Insurance Entities, policy fees collected from policyholders by the Company’s wholly-owned managing general agent subsidiary and payment plan fees charged to policyholders who choose to pay their premiums in installments. The Company’s wholly-owned adjusting company receives claims-handling fees from the Insurance Entities. The Insurance Entities are reimbursed for these fees on claims that are subject to recovery under the Insurance Entities’ respective reinsurance programs. These fees, after expenses, are recorded in the Condensed Consolidated Financial Statements as an adjustment to losses and loss adjustment expense (“LAE”). Basis of Presentation The Company has prepared the accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the Financial Statements do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for annual financial statements. Therefore, the Financial Statements should be read in conjunction with the audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 28, 2022. The Condensed Consolidated Balance Sheet at December 31, 2021 was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included in the Financial Statements. The results for interim periods do not necessarily indicate the results that may be expected for any other interim period or for the full year. To conform to the current period presentation, certain amounts in the prior periods’ condensed consolidated financial statements and notes have been reclassified. Such reclassifications were of an immaterial amount and had no effect on net income or stockholders’ equity. The Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, as well as variable interest entities (“VIE”) in which the Company is determined to be the primary beneficiary. All material intercompany balances and transactions have been eliminated in consolidation. The preparation of 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 as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company’s primary use of estimates is in the recognition of liabilities for unpaid losses, loss adjustment expenses, subrogation recoveries and reinsurance recoveries. Actual results could differ from those estimates.
