Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	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 three wholly-owned insurance subsidiaries. Our original insurance subsidiary is United Property & Casualty Insurance Company (UPC), which was formed in Florida in 1999 and has operated continuously since that time. 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. We currently offer personal residential insurance in seven states, under authorization from the insurance regulatory authorities in each state. In addition, we write commercial residential insurance in three states: Florida, South Carolina, and Texas. We are also licensed to write personal residential insurance in an additional eleven states; however, we have not commenced writing or no longer write in these states. 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. As a result, these policies will no longer be covered under this agreement. 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 (personal lines) and commercial residential property and casualty insurance policies (commercial lines). Our chief operating decision maker is our President, who makes decisions to allocate resources and assesses performance at both segment levels, as well as at the corporate level. (b)Consolidation and Presentation We prepare our unaudited condensed consolidated interim financial statements in conformity with U.S. generally accepted accounting principles (GAAP). We have condensed or omitted certain information and footnote disclosures normally included in the annual consolidated financial statements presented in accordance with GAAP. In management's opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of interim periods. We include all of our subsidiaries in our consolidated financial statements, eliminating intercompany balances and transactions during consolidation. Our unaudited condensed consolidated interim financial statements and footnotes should be read in conjunction with our consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2021. While preparing our unaudited condensed 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 unaudited condensed 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 Unaudited Condensed Consolidated Balance Sheets and Unaudited Condensed Consolidated Statements of Comprehensive Loss, we generally use the term loss(es) to collectively refer to both loss and loss adjustment expenses. Our results of operations and our cash flows as of the end of the interim periods reported herein do not necessarily indicate our results for the remainder of the year or for any other future period. (c)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 three and six months ended June 30, 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 quarter ended June 30, 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.
