	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 and valuation allowance on deferred tax assets.
