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, four wholly-owned insurance subsidiaries, and one majority-owned insurance subsidiary. Our largest insurance subsidiary is United Property & Casualty Insurance Company (UPC), which was formed in Florida in 1999 and has operated continuously since that time. Our four other insurance subsidiaries are Family Security Insurance Company, Inc. (FSIC), acquired via merger on February 3, 2015, Interboro Insurance Company (IIC), acquired via merger on April 29, 2016, American Coastal Insurance Company (ACIC), acquired via merger on April 3, 2017, and Journey Insurance Company (JIC). JIC was formed in strategic partnership with a subsidiary of Tokio Marine Kiln Group Limited (Kiln) on August 30, 2018. The Kiln subsidiary holds a noncontrolling interest in JIC. Our other subsidiaries include United Insurance Management, L.C. (UIM), a managing general agent that manages substantially all aspects of UPC and FSIC's business, as well as JIC's personal residential business; Skyway Claims Services, LLC, which provides claims adjusting services to UPC, FSIC, ACIC and JIC; AmCo Holding Company, LLC (AmCo) and Family Security Holdings, LLC (FSH), which are holding company subsidiaries that consolidate their respective insurance companies; 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 11 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 property and casualty insurance in an additional six states; however, we have not commenced writing in these states. Effective December 31, 2021, we entered into a quota share reinsurance agreement with Homeowners Choice Property and Casualty, Inc. (HCPCI). Under the terms of this agreement, we will cede 85% of our in-force, new, and renewal policies in the states of Georgia, North Carolina and South Carolina. Effective June 1, 2021, we entered into a quota share reinsurance agreement with HCPCI and TypTap Insurance Company (TypTap). Under the terms of this agreement, we will cede 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 is 50% to HCPCI and 50% to TypTap. HCPCI is responsible for processing all claims as a part of this agreement. As the transfer of each state is completed, the quota share coverage for the transitioned state will no longer be in effect. As of December 31, 2021, we have completed the transfer of our Rhode Island and Connecticut policies. 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) Impact of COVID-19 and Financial Status We are committed to maintaining a stable and secure business for our employees, agents, customers and stockholders. During the second half of 2020, we were able to resume hiring activities, despite the limits on in-person interviews and on-boarding procedures resulting from COVID-related protocols. In addition, we have converted to virtual sales processes to enable our agents to continue their activities. We believe these activities, collectively, help ensure the health and safety of our employees through adherence to CDC, state and local government work guidelines. We have not experienced a material impact from COVID-19 on our business operations, financial position, liquidity or our ability to service our policyholders to date, with the exceptions of fluctuations in our investment portfolios due to volatility of the equity securities markets, as further described in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-K. 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, 2021. We did not incur material claims or significant disruptions to our business for the year ended December 31, 2021 as a result of COVID-19. At this time, it is not possible to reasonably estimate the extent of the impact of the economic uncertainties on our business, results of operations and financial condition in future periods, due to uncertainty regarding the duration of the COVID-19 pandemic, but we will continue to respond to the COVID-19 pandemic and take reasonable measures to make sure customers continue to be served without interruption.
