CY2022	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The major estimates reflected in the Company’s consolidated financial statements include, but are not limited to, the loss and loss adjustment expense reserves, estimates of written and earned premiums and fair value of financial instruments.
