Condensed Financial Information Disclosure [Abstract]
Schedule II - Condensed Financial Information of Registrant	NOTE 1 – GENERAL The financial statements of the Registrant should be read in conjunction with the consolidated financial statements in “Item 8.” Nature of Operations and Basis of Presentation Universal Insurance Holdings, Inc. is a Delaware corporation incorporated in 1990. The Parent Company is an insurance holding company whose wholly-owned subsidiaries perform all aspects of insurance underwriting, distribution and claims. Through its wholly-owned subsidiaries, including Universal Property & Casualty Insurance Company (“UPCIC”) and American Platinum Property and Casualty Insurance Company (“APPCIC”), the Parent Company is principally engaged in the property and casualty insurance business offered primarily through a network of independent agents. Risk from catastrophic losses is managed through the use of reinsurance agreements. The Parent Company generates revenues from earnings on investments and management fees. The Parent Company also receives distributions of earnings from its insurance and non-insurance subsidiaries. Certain amounts in the prior periods’ consolidated financial statements have been reclassified in order to conform to current period presentation. Such reclassifications had no effect on net income or stockholders’ equity. Capital Contributions to Subsidiaries During the years ended December 31, 2023, 2022, and 2021, the Parent Company made capital contributions of $72.0 million, $84.0 million and $92.0 million, respectively, to UPCIC to increase UPCIC’s statutory capital and surplus. During the year ended December 31, 2023, the Parent Company did not make a capital contribution to APPCIC. During the year ended December 31, 2022, the Parent Company made capital contributions of $3.0 million to increase APPCIC’s statutory capital and surplus. There were no capital contributions by the Parent Company to APPCIC during 2021. Dividends received from Subsidiaries The Parent Company received distributions from the earnings of its non-insurance consolidated subsidiaries of $164.1 million, $231.9 million, and $149.9 million during the years ended December 31, 2023, 2022, and 2021, respectively. There were no dividends paid by UPCIC and APPCIC to the Parent Company during the years ended December 31, 2023, 2022, and 2021. NOTE 2 - INTERCOMPANY NOTE RECEIVABLE During the years ended December 31, 2023, the Parent Company did not fund Subordinated Surplus Debentures (“Surplus Debentures”) to UPCIC. During the year ended December 31, 2022, the Parent Company funded $110.0 million of surplus debentures through PSI, the Insurance Entities’ parent company, to UPCIC to increase UPCIC’s statutory capital and surplus. During the year ended December 31, 2023 the Parent Company did not fund surplus debentures to APPCIC. During the year ended December 31, 2022, the Parent Company funded $4.0 million Surplus Debenture through PSI to APPCIC to increase APPCIC statutory capital and surplus. Intercompany note receivable is stated separately in the accompanying Condensed Consolidated Balance Sheets. Effective in 2021 for UPCIC and 2022 for APPCIC, the holding company has put in place an ongoing surplus note arrangement with the Insurance Entities, which has been approved by the Florida Office of Insurance Regulation (“FLOIR”) as the Insurance Entities’ domestic regulator. Surplus debentures are unsecured debt issued by the Insurance Entities that are subordinated to all claims by policyholders and creditors, with interest and principal payments on the surplus note to the holding company being made only upon the FLOIR’s express approval. Surplus debentures are considered bonds in function and payout structure, but are accounted for as equity in the statutory reporting of the Insurance Entities. The holding company has outstanding with the Insurance Entities $134.0 million in surplus notes. Under the arrangement, interest accrues at a variable rate (currently 10.54%) on the outstanding surplus note balances and, if approved by the FLOIR, is payable annually to the holding company. In 2023, UPCIC received approval from its Florida regulator to permit UPCIC to pay interest accruing from surplus notes outstanding during 2023.

NOTE 4 – SUBSEQUENT EVENTS The Parent Company performed an evaluation of subsequent events through the date the financial statements were issued and determined there were no recognized or unrecognized subsequent events that would require an adjustment or additional disclosure in the consolidated financial statements as of December 31, 2023.
