Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared the accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the Financial Statements do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“U.S. GAAP”) for annual financial statements. Therefore, the Financial Statements should be read in conjunction with the audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 26, 2021. The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included in the Financial Statements. The results for interim periods do not necessarily indicate the results that may be expected for any other interim period or for the full year. To conform to the current period presentation, certain amounts in the prior periods’ condensed consolidated financial statements and notes have been reclassified. Such reclassifications were of an immaterial amount and had no effect on net income or stockholders’ equity. The Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, as well as variable interest entities (“VIE”) in which the Company is determined to be the primary beneficiary. All material intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company’s primary use of estimates is in the recognition of liabilities for unpaid losses, loss adjustment expenses, subrogation recoveries and reinsurance recoveries. Actual results could differ from those estimates.
Assets Held for Sale	Assets Held for Sale. The Company considers properties, including land, to be assets held for sale when (1) management commits to a plan to sell the property; (2) it is unlikely that the disposal plan will be significantly modified or discontinued; (3) the property is available for immediate sale in its present condition; (4) actions required to complete the sale of the property have been initiated; (5) sale of the property is probable and the Company expects the completed sale will occur within one year; and (6) the property is actively being marketed for sale at a price that is reasonable given our estimate of current market value. Upon designation of a property as an asset held for sale, we record the property’s value at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and the Company ceases depreciation. Assets held for sale are stated separately in the accompanying Condensed Consolidated Balance Sheets.
