Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Business Horace Mann Educators Corporation is a holding company for insurance subsidiaries that market and underwrite personal lines of property and casualty insurance products (primarily personal lines of auto and property insurance), life insurance products, retirement products (primarily tax-qualified fixed and variable annuities), voluntary supplemental insurance products (primarily cancer, heart, hospital, supplemental disability and accident coverages), and employer-sponsored group benefit products (primarily short-term and long-term group disability, and group term life coverages), primarily to K-12 teachers, administrators and other employees of public schools and their families (collectively, HMEC, the Company or Horace Mann). As described more fully in Note 2, the Company acquired Madison National Life Insurance Company, Inc. (Madison National) effective January 1, 2022. In conjunction with the acquisition, management changed how it manages and conducts business resulting in three operating segments: (1) Property & Casualty, (2) Life & Retirement, and (3) Supplemental & Group Benefits (which includes the results of Madison National). 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, 2021. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full year. The accompanying Consolidated Financial Statements and Notes thereto are unaudited. These financial statements 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 Company's Annual Report on Form 10-K for the year ended December 31, 2021. The Company has reclassified the presentation of certain prior period information to conform to the current year's presentation. Consolidation All intercompany transactions and balances between HMEC and its subsidiaries and affiliates have been eliminated. 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, 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, evaluation of goodwill and intangible assets for impairment, valuation of annuity and life deferred policy acquisition costs, valuation of liabilities for property and casualty unpaid claims and claim expenses, valuation of certain investment contracts and policy reserves and valuation of assets acquired and liabilities assumed under purchase accounting and purchase price allocation. Future Adoption of New Accounting Standards Accounting for Long-Duration Insurance Contracts In August 2018, the FASB issued targeted improvements to the accounting and disclosure guidance for long-duration insurance contracts. Under the new guidance, the cash flow assumptions used to measure the liability for future policy benefits for traditional insurance contracts will be required to be updated at least annually with changes recognized as a benefit expense (i.e., assumptions will no longer be locked-in). Insurance entities will be required to use a standard discount rate to measure the liabilities that will be equivalent to the yield from a high-quality bond. The new guidance also changes the amortization of deferred policy acquisition costs (DAC) to be on a constant-level basis over the expected term of the related contracts with no interest accruing on the DAC balance. The new guidance also introduces a new category of contract features associated with deposit type contracts referred to as market risk benefits (MRBs). Contract features meeting the definition of a MRB will be measured at fair value. New disclosures will be required for long-duration insurance contracts in order to provide better transparency into the exposure of insurance entities and the drivers of their results. For public business entities, the guidance is effective for annual reporting periods beginning after December 15, 2022, including interim periods within those years. With regards to the liability for future policy benefits and DAC, the guidance applies to contracts in force as of the beginning of the earliest period presented and may be applied retrospectively. With regards to MRBs, the guidance is to be applied retrospectively at the beginning of the earliest period presented. Early adoption is permitted. Management is currently evaluating the impact this guidance will have on the results of operations and financial position of the Company.
