Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of EstimatesThe preparation of the consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company's consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, reinsurance recoverable on unpaid losses, the fair values of investments, valuation allowance on deferred tax assets and the valuation of stock-based compensation.
