Accounting Policies [Abstract]
Basis of Accounting	The unaudited consolidated financial statements of the Company as of March 31, 2024 and December 31, 2023 and for the three months ended March 31, 2024 and 2023 include all adjustments, consisting of normal recurring accruals, which, in the opinion of management, are necessary for a fair statement of the results on an interim basis. Certain financial information, which is normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), has been omitted since it is not required for interim reporting purposes. The December 31, 2023 consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The results for the three months ended March 31, 2024 and 2023 are not necessarily indicative of the results for a full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the years ended December 31, 2023, 2022 and 2021, included in the Company’s most recent Form 10-K filing.
Voting and Variable Interest Entities	The Company consolidates the results of operations and financial position of all voting interest entities ("VOE") in which the Company has a controlling financial interest and all variable interest entities ("VIE") in which the Company is considered to be the primary beneficiary. The consolidation assessment, including the determination as to whether an entity qualifies as a VIE or VOE, depends on the facts and circumstances surrounding each entity.
Use of Estimates	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 (and disclosure of contingent assets and liabilities) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Ultimate actual results could differ, possibly materially, from those estimates.
Consolidation	All intercompany accounts and transactions have been eliminated.
Adoption of New Accounting Standards and Future Adoption of Recently Issued Accounting Standards	Adoption of New Accounting Standards The Company did not adopt any new accounting standards that had a material impact during the three months ended March 31, 2024. Future Adoption of Recently Issued Accounting Standards The Company assessed the adoption impacts of recently issued accounting standards that are effective after 2024 by the Financial Accounting Standards Board on the Company’s consolidated financial statements. Additionally, the Company assessed whether there have been material updates to previously issued accounting standards that are effective after 2024. There were no accounting standards identified, other than those directly referenced below, that are expected to have a material impact to Group. Improvements to Income Tax Disclosures. In December 2023, the Financial Accounting Standards Board issued Accounting Standard Update No. 2023-09, which requires expanded income tax disclosures, including the disaggregation of existing disclosures related to the tax rate reconciliation and income taxes paid. The guidance is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on the Company's financial statement disclosures.
Fair Value of Financial Instruments	Equity securities denominated in U.S. currency with quoted prices in active markets for identical assets are categorized as Level 1 since the quoted prices are directly observable. Equity securities traded on foreign exchanges are categorized as Level 2 due to the added input of a foreign exchange conversion rate to determine fair value. The Company uses foreign currency exchange rates published by nationally recognized sources. Fixed maturity securities listed in the tables have been categorized as Level 2, since a particular security may not have traded but the pricing services are able to use valuation models with observable market inputs such as interest rate yield curves and prices for similar fixed maturity securities in terms of issuer, maturity and seniority. For foreign government securities and foreign corporate securities, the fair values provided by the third party pricing services in local currencies, and where applicable, are converted to U.S. dollars using currency exchange rates from nationally recognized sources. In addition, some of the fixed maturities with fair values categorized as Level 3 result when prices are not available from the nationally recognized pricing services and are obtained from investment managers and are derived using unobservable inputs. The Company will value the securities with unobservable inputs using comparable market information or receive fair values from investment managers. The investment managers may obtain non-binding price quotes for the securities from brokers. The single broker quotes are provided by market makers or broker-dealers who are recognized as market participants in the markets in which they are providing the quotes. The prices received from brokers are reviewed for reasonableness by the third party asset managers and the Company. If the broker quotes are for foreign denominated securities, the quotes are converted to U.S. dollars using currency exchange rates from nationally recognized sources. The composition and valuation inputs for the presented fixed maturities categories Level 1 and Level 2 are as follows: •U.S. Treasury securities and obligations of U.S. government agencies and corporations are primarily comprised of U.S. Treasury bonds, and the fair value is based on observable market inputs such as quoted prices, reported trades, quoted prices for similar issuances or benchmark yields; •Obligations of U.S. states and political subdivisions are comprised of state and municipal bond issuances, and the fair values are based on observable market inputs such as quoted market prices, quoted prices for similar securities, benchmark yields and credit spreads; •Corporate securities are primarily comprised of U.S. corporate and public utility bond issuances, and the fair values are based on observable market inputs such as quoted market prices, quoted prices for similar securities, benchmark yields and credit spreads; •Asset-backed and mortgage-backed securities fair values are based on observable inputs such as quoted prices, reported trades, quoted prices for similar issuances or benchmark yields and cash flow models using observable inputs such as prepayment speeds, collateral performance and default spreads; •Foreign government securities are comprised of global non-U.S. sovereign bond issuances, and the fair values are based on observable market inputs such as quoted market prices, quoted prices for similar securities and models with observable inputs such as benchmark yields and credit spreads and then, where applicable, converted to U.S. dollars using an exchange rate from a nationally recognized source; •Foreign corporate securities are comprised of global non-U.S. corporate bond issuances, and the fair values are based on observable market inputs such as quoted market prices, quoted prices for similar securities and models with observable inputs such as benchmark yields and credit spreads and then, where applicable, converted to U.S. dollars using an exchange rate from a nationally recognized source.
