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, 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 IIC; 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; and Skyway Legal Services, LLC, which provides claims litigation services to our insurance companies; and Skyway Technology Services, LLC, which provides technological and distribution services to our insurance companies. Our primary products are homeowners' and commercial residential property insurance, which we currently offer 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, 2020, we entered into a quota share reinsurance agreement with Homeowners Choice Property and Casualty, Inc (HCP). Under the terms of this agreement, HCP provided 69.5% quota share reinsurance on in-force, new, and renewal policies in Connecticut, Massachusetts, New Jersey, and Rhode Island effective December 31, 2020, until June 1, 2021. Effective June 1, 2021, we entered into a quota share reinsurance agreement with HCP 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 HPC and 50% to Typtap. HCP is responsible for processing all claims as a part of this agreement. We conduct our operations under one reportable segment, property and casualty insurance policies. Our chief operating decision maker is our President, who makes decisions to allocate resources and assesses performance 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, 2020. 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 Income (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 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 I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Form 10-Q. 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, 2021. We did not incur material claims or significant disruptions to our business for the three and six-months ended June 30, 2021. 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.
