Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation	ORGANIZATION, CONSOLIDATION AND PRESENTATION (a)Business United Insurance Holdings Corp. (referred to in this document as we, our, us, the Company or UPC Insurance) is a property and casualty insurance holding company that sources, writes and services residential personal and commercial property and casualty insurance policies using a network of agents and wholly-owned insurance subsidiaries. Our original insurance subsidiary is United Property & Casualty Insurance Company (UPC), which was formed in Florida in 1999. Our two other insurance subsidiaries are Interboro Insurance Company (IIC), acquired via merger on April 29, 2016; and American Coastal Insurance Company (ACIC), acquired via merger on April 3, 2017. Our other subsidiaries include United Insurance Management, L.C. (UIM), a managing general agent that manages substantially all aspects of UPC's business; Skyway Claims Services, LLC, which provides claims adjusting services to UPC, and ACIC; AmCo Holding Company, LLC (AmCo), which is a holding company subsidiary that consolidates its respective insurance company; BlueLine Cayman Holdings (BlueLine), which reinsures portfolios of excess and surplus policies; UPC Re, which provides a portion of the reinsurance protection purchased by our insurance subsidiaries when needed; Skyway Reinsurance Services, LLC, which provides reinsurance brokerage services for our insurance companies; Skyway Legal Services, LLC, which provides claims litigation services to our insurance companies; and Skyway Technologies, LLC, a managing general agent that provides technological and distribution services to our insurance companies. Our primary products are homeowners' and commercial residential property insurance. In 2022 we offered personal residential insurance in six states, under authorization from the insurance regulatory authorities in each state. In addition, we write commercial residential insurance in Florida. During 2022, we also wrote commercial residential insurance in South Carolina, and Texas, however, effective May 1, 2022, we no longer write in these states. We are also licensed to write property and casualty insurance in an additional twelve states; however, we have not commenced writing or no longer write in these states. On August 25, 2022, we announced that UPC had filed plans for withdrawal in the states of Florida, Louisiana, and Texas and intended to file a plan for withdrawal in the state of New York. All filed plans entail non-renewing personal lines policies in these states. Additionally, we announced that Demotech, Inc. (Demotech), an insurance rating agency, notified UPC of its intent to withdraw UPC's Financial Stability Rating. On December 5, 2022, the Florida Office of Insurance Regulation ("FLOIR") issued Consent Order No. 303643-22- CO that provides for the administrative supervision and approval of the plan of run-off for UPC (the "Consent Order"). The Consent Order provides formal approval of UPC's Plan of Run-Off (the "Plan") to facilitate a solvent wind down of its affairs in an orderly fashion. Additionally, in connection with the Plan, IIC has agreed to not pay ordinary dividends without the prior approval of the New York Department of Financial Services until January 1, 2025. On February 10, 2023, we announced that a solvent run-off of UPC was unlikely and on February 27, 2023, UPC was placed into receivership with the Florida Department of Financial Services which divested our ownership of UPC. Effective June 1, 2022, we merged our majority-owned insurance subsidiary, Journey Insurance Company (JIC) into ACIC, with ACIC being the surviving entity. JIC was formed in strategic partnership with a subsidiary of Tokio Marine Kiln Group Limited (Kiln) on August 30, 2018, and operated independently from ACIC prior to the merging of the entities. The Kiln subsidiary held a noncontrolling interest in JIC, which was terminated prior to the merger. Effective June 1, 2022, we entered into a quota share reinsurance agreement with TypTap Insurance Company (Typtap). Under the terms of this agreement, we cede 100% of our in-force, new, and renewal policies in the states of Georgia, North Carolina and South Carolina. Effective June 1, 2022, we began the transition of South Carolina policies to Homeowners Choice Property and Casualty, Inc (HCPCI) in connection with our renewal rights agreement. Effective October 1, 2022, transitioned Georgia policies to HCPCI in connection with our renewal rights agreement. Effective December 1, 2022, we began the transition of North Carolina policies to HCPCI in connection with our renewal rights agreement. As a result, these policies will no longer be covered under this agreement upon their renewal. This agreement replaces the 85% quota share agreement with HCPCI effective December 31, 2021. Effective May 31, 2022, we merged Family Security Insurance Company, Inc. (FSIC) into UPC, with UPC being the surviving entity. FSIC was acquired via merger on February 3, 2015, and operated independently from UPC prior to the merging of the entities. In conjunction with the merger, we dissolved Family Security Holdings (FSH), a holding company subsidiary that consolidated its respective insurance company, FSIC. Effective June 1, 2021, we entered into a quota share reinsurance agreement with HCPCI and TypTap. Under the terms of this agreement, we ceded 100% of our in-force, new, and renewal policies in the states of Connecticut, New Jersey, Massachusetts, and Rhode Island. The cession of these policies was 50% to HCPCI and 50% to TypTap. HCPCI is responsible for processing all claims as a part of this agreement. As of April 1, 2022, we completed the transition of all policies in these four states to HCPCI in connection with our renewal rights agreement (Northeast Renewal Agreement) to sell UPC's personal lines homeowners business in these states. We conduct our operations under two reportable segments, personal residential property and casualty insurance policies and commercial residential property and casualty insurance policies. Our chief operating decision maker is our President, who makes decisions to allocate resources and assesses performance at both segment levels as well as the corporate level. (b)Consolidation and Presentation We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). While preparing our consolidated financial statements, we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, as well as reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Reported amounts that require us to make extensive use of estimates include our reserves for unpaid losses and loss adjustment expenses, investments and goodwill. Except for the captions on our Consolidated Balance Sheets and Consolidated Statements of Comprehensive Loss, we generally use the term loss(es) to collectively refer to both loss and loss adjustment expenses. We include all of our subsidiaries in our consolidated financial statements, eliminating intercompany balances and transactions during consolidation. (c) Going Concern In accordance with ASC Subtopic 205-40, Presentation of Financial Statements—Going Concern (“ASC 205-40”), the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its obligations as they become due within one year after the date that the financial statements are issued. As required under ASC 205-40, management’s evaluation should initially not take into consideration the potential mitigating effects of management’s plans that have not been fully implemented as of the date the financial statements are issued. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. In performing this evaluation, we concluded that under the standards of ASC 205-40 the following conditions raised substantial doubt about our ability to continue as a going concern: (1) the ability to obtain reinsurance recoveries allocated to ACIC under the catastrophe treaties covering Hurricane Ian where ACIC’s affiliate, United Property & Casualty Insurance Company (“UPC”) is also a party, and (2) the ability to obtain adequate reinsurance to meet the requirements of the FLOIR and Demotech, the rating agency, for future reinsurance periods. Upon completion of the Company’s year-end review of unpaid loss and loss adjustment reserves with our independent actuarial firm, our insurance entity, UPC, increased its gross loss estimate related to Hurricane Ian to $864 million. UPC’s loss estimate of $864 million fully exhausts all reinsurance available to UPC for this specific event, based on the reinsurance allocation agreement discussed below. As a result of this development, the Company immediately notified the FLOIR that UPC was expected to be insolvent as of December 31, 2022. On February 27, 2023, UPC was ordered into receivership for purposes of liquidation, with the Florida Department of Financial Services (the “DFS”) appointed as the receiver, which deconsolidated UPC from the group. The Company’s other insurance subsidiaries are not parties to the receivership and continue to operate. However, ACIC’s catastrophe reinsurance coverage is a part of a combined reinsurance program with UPC. To properly allocate the reinsurance recoverables under the shared catastrophe treaties, UPC and ACIC entered a reinsurance allocation agreement that became effective on June 1, 2022 (the “Allocation Agreement”). The Allocation Agreement was filed with and approved by the FLOIR on December 5, 2022. However, ACIC now believes there is uncertainty regarding the timing of receipt of both recoveries currently held by UPC that are allocated to ACIC and future recoverables now that UPC has been placed into receivership. As of December 31, 2022, UPC held recoveries due to ACIC totaling $31,306,000. On April 5, 2023, the Company filed a Motion for Release of Property of ACIC in the Circuit Court of the Second Judicial Circuit for Leon County, Florida, requesting that UPC immediately remit to ACIC reinsurance recoveries currently held by UPC and reinsurance recoveries recovered by UPC in the future in accordance with the Company’s Allocation Agreement. Alternatively, ACIC requested reinsurance recoveries remitted to UPC be placed into a segregated account for future reconciliation and remittance to ACIC. On April 13, 2023, the DFS filed a response to the Company’s motion, objecting to ACIC’s position. On April 14, 2023, the Court denied ACIC’s motion without prejudice. As a result of the foregoing, management believes substantial doubt exists regarding the Company’s ability to continue as a going concern. As of December 31, 2022, ACIC calculates it is due approximately $273 million from the private reinsurance program described above in accordance with the Allocation Agreement approved by the FLOIR, related to its ultimate gross Hurricane Ian loss. To the extent that these reinsurance recoverables are not received timely and treated as a nonadmitted asset of ACIC, which would be excluded from regulatory capital and surplus, the Company may not have sufficient liquidity to continue to operate. Management believes that the ability for ACIC to obtain adequate reinsurance to meet its needs for the June 1, 2023 to May 31, 2024 catastrophe cover can only be accomplished assuming that recoveries due to ACIC pursuant to the Allocation Agreement can be resolved in short order. Such conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for one year following the issuance of the financial statements. The Company intends to continue to work towards a fair and equitable resolution regarding these recoveries, however no assurance can be given that it will receive all or any portion of the reinsurance recoverables that it believes are due to ACIC. (d) Impact of COVID-19 and Financial Status We did not experience a material impact from COVID-19 on our business operations, financial position, liquidity or our ability to service our policyholders during the year ended December 31, 2022. In addition, the COVID-19 pandemic and resulting global disruptions did not have a material impact on our access to credit and capital markets needed to maintain sufficient liquidity for our continued operating needs during the year ended December 31, 2022. Additionally, during the fourth quarter of 2021 we implemented our new flexible work policy. This policy allows all employees to work remotely permanently, with the return to our offices being completely voluntary at this time. We will continue to respond to the COVID-19 pandemic and take reasonable measures to make sure customers continue to be served without interruption.
