All material intercompany transactions and balances have been eliminated upon consolidation. All foreign currency amounts in the condensed consolidated statement of operations and comprehensive loss have been translated using an average rate for the reporting period. All foreign currency balances in the balance sheet have been translated using the spot rate at the end of the reporting period.

Although the Company did not see a material impact on its results of operations for the three and nine months ended September 30, 2021 due to the COVID-19 pandemic, the Company cannot predict the duration or magnitude of the pandemic or the full impact that it may have on the Company’s financial condition and results of operations, business operations, and workforce. </span></div><div style="margin-top:12pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Unaudited interim financial information</span></div>In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for the fair presentation of its financial position and its results of operations, changes in stockholders’ equity (deficit) and cash flows. The condensed consolidated balance sheet at December 31, 2020, was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the fiscal year ended December 31, 2020 contained in the Company’s Annual Report on Form 10-K
	us-gaap	Use Of Estimates UseOfEstimates	The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates estimates, including those related to contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenue and expense during the reporting period. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in the Company’s condensed consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, reinsurance recoverables on unpaid losses, valuation allowance on deferred tax assets and valuation on stock-based compensation prior to the Company's Initial Public Offering (the "IPO").
