Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation—In our opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. All such adjustments are of a normal and recurring nature. These condensed consolidated financial statements are unaudited and, accordingly, should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 23, 2022, or the 2021 10-K.
Basis of Consolidation | Basis of Consolidation—The unaudited condensed consolidated financial statements include the accounts of Root, Inc. and its subsidiaries, all of which are wholly owned. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP.
Use of Estimates | Use of Estimates—The preparation of the unaudited condensed consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in our unaudited condensed consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, allowance for expected credit losses on premium receivables and valuation allowances for income taxes.
