Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and with the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in conformity with GAAP, but are not required for interim reporting purposes, have been omitted. These Consolidated Financial Statements and Notes thereto should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Part II - Item 8 of the Company's Annual Report on Form 10-K for the year ended December 31, 2023. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full year. The accompanying Consolidated Financial Statements and Notes thereto are unaudited and reflect all adjustments (generally consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods. The Company's significant accounting policies are summarized in Part II - Item 8, Note 1 of the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. The Company has reclassified the presentation of certain prior period information to conform to the current year's presentation.
Consolidation	Consolidation All intercompany transactions and balances between HMEC and its subsidiaries and affiliates have been eliminated.
Use of Estimates	Use of Estimates The preparation of consolidated 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 reporting date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The most significant critical accounting estimates include valuation of hard-to-value fixed maturity securities, evaluation of credit loss impairments for fixed maturity securities, valuation of future policy benefit reserves, and valuation of liabilities for property and casualty unpaid claims and claim expense reserves.
Future Adoption of New Accounting Standards	Future Adoption of New Accounting Standards Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This update will improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 includes: 1) a requirement to disclose significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, 2) a requirement to disclose an amount for other segment items by reportable segment and a description of its composition, 3) a requirement to disclose a reportable segments profit or loss and assets currently required by Topic 280 in interim periods, 4) clarifies that in addition to the measure that is most consistent with the measurement principles under generally accepted accounting principles (GAAP), a public entity is not precluded from reporting additional measures of a segment's profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources, and 5) a requirement to disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This guidance will be effective for the Company for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows. Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update will improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the Company for annual periods beginning after December 15, 2024 and interim periods beginning after December 15, 2025. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows.
