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, 2024. The results of operations for the three and nine months ended September 30, 2025 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, 2024.
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 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. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-04, 03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This guidance will improve the disclosures regarding a public business entity’s expenses by requiring (1) disclosure of the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption, (2) inclusion of certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements, (3) disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and (4) disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this guidance will be effective for the Company for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows.
