	us-gaap	Use Of Estimates UseOfEstimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about the effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these consolidated financial statements relate to reserves for losses and loss adjustment expenses ("LAE"). Actual results could differ from those estimates. See Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023
