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), worksite direct 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). The Company conducts and manages its business in four reporting segments: (1) Property & Casualty, (2) Life & Retirement, (3) Supplemental & Group Benefits and (4) Corporate & Other. 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, 2022. The results of operations for the three months ended March 31, 2023 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, 2022. 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 expense reserves, valuation of liabilities for group benefits unpaid claims and claim expense reserves, valuation of future policy benefit reserves and policyholders' account balances and valuation of long-duration insurance contracts under the new accounting guidance in ASU 2018-12. Adoption of New Accounting Standards Accounting for Long-Duration Insurance Contracts In August 2018, the FASB issued ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, as clarified and amended by (i) ASU 2019-09, Financial Services - Insurance (Topic 944): Effective Date, and (ii) ASU 2020-11, Financial Services - Insurance (Topic 944): Effective Date and Early Application (collectively referred to herein as ASU 2018-12). ASU 2018-12 changed existing recognition, measurement, presentation, and disclosure requirements for long-duration contracts. ASU 2018-12 includes: (1) a requirement to review and, if there is a change, update cash flow assumptions used to measure the liability for future policy benefits (LFPB) at least annually, and to update the discount rate assumption quarterly, (2) a requirement to account for market risk benefits (MRBs) at fair value, (3) simplified amortization for deferred policy acquisition costs (DAC), and (4) enhanced financial statement presentation and disclosures. ASU 2018-12 became effective for the Company for interim and annual periods beginning after December 15, 2022. The Company adopted ASU 2018-12 for LFPB and DAC on a modified retrospective basis such that those balances were adjusted to conform to ASU 2018-12 on January 1, 2021. The Company adopted ASU 2018-12 for MRBs on a full retrospective basis, using hindsight where necessary. For variable annuities, actuarial assumptions (mortality, lapse, and premium payment patterns) used to measure MRBs were unobservable for years prior to 2006 and thus, hindsight was used to determine relevant assumptions for transition purposes. The factors used in applying hindsight included internal experience studies, the historical economic environment, actual performance of the business, and relevant industry information. The following table summarizes the balance of and changes in LFPB on January 1, 2021 due to adoption of ASU 2018-12. The impact of shifts between deferred profit liabilities (DPL) and LFPB for limited-payment products are presented as offsetting line items in the effect of net premiums exceeding gross premiums and the effect of decrease/increase of DPL.

At transition, the Company had several instances, at the cohort level, where net premiums exceeded gross premiums which were recorded as an adjustment to retained earnings. For DAC, the Company removed shadow adjustments previously recorded in accumulated other comprehensive income (loss) (i.e., AOCI) for the impact of net unrealized investment gains (losses) that were included in the pre-ASU 2018-12 expected gross profits amortization calculation as of the transition date. For MRBs, the transition adjustment to AOCI relates to the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date. The remaining difference between the fair value and carrying amount of MRBs at transition, excluding the amounts recorded in AOCI, was recorded as an adjustment to retained earnings as of the transition date. While the requirements of ASU 2018-12 represent a significant change from legacy GAAP, the adoption of ASU 2018-12 did not impact cash flows on the Company’s policies, or the underlying economics of the Company’s business. The Company's insurance subsidiaries' risk-based capital amounts and ratios, and regulatory dividends are not impacted as the National Association of Insurance Commissioners (NAIC) rejected ASU 2018-12. See Note 11 for summarization of the effects of adopting ASU 2018-12 on the Company's 2022 Consolidated Financial Statements. Significant Accounting Policies The following significant accounting policy has been added to reflect the Company's adoption of ASU 2018-12 as described above. Liability for Future Policy Benefits LFPB, which is the present value of estimated future policy benefits to be paid to or on behalf of policyholders and certain related expenses less the present value of estimated future net premiums to be collected from policyholders, is accrued as premium revenue. The liability is estimated using current assumptions that include discount rate, mortality, lapses, and expenses. These current assumptions are based on judgments that consider the Company's historical experience, industry data, and other factors. For traditional, limited-payment and supplemental health contracts, such contracts are grouped into cohorts by contract type and issue year. The liability is adjusted for differences between actual and expected experience. With the exception of the expense assumption, the Company reviews its historical and future cash flow assumptions at least annually and updates the net premium ratio used to calculate the liability each time the assumptions are changed. The Company has elected to use expense assumptions that are locked-in at contract inception and are not subsequently reviewed or updated. At least annually, the Company updates its estimate of cash flows expected over the entire life of a group of contracts using actual historical experience and current future cash flow assumptions. These updated cash flows are used to calculate the revised net premiums and net premium ratio, which are used to derive an updated LFPB as of the beginning of the current reporting period, discounted at the original contract issuance discount rate. This amount is then compared to the carrying amount of the liability as of that same date, before updating cash flow assumptions, to determine the current period change in liability estimate. This current period change in liability estimate is the liability remeasurement gain or loss. The impact of updated cash flow assumptions as well as the periodic liability remeasurement gain or loss is recognized as Benefits, claims and settlement expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss). In subsequent periods, the revised net premiums are used to measure LFPB, subject to future revisions. For traditional and limited-payment contracts, a standard discount rate is used to measure the liabilities that is equivalent to the yield from an A-rated bond. The discount rate assumption is updated quarterly and used to remeasure the liability at the reporting date, with the resulting change reflected in other comprehensive income. For liability cash flows that are projected beyond the duration of market-observable A- rated bond, the Company uses the last market-observable yield level, and uses linear interpolation to determine yield assumptions for durations that do not have market-observable yields. Deferred Profit Liability For limited-payment products, gross premiums received in excess of net premiums are deferred at initial recognition as a DPL. Gross premiums are measured using assumptions consistent with those used in the measurement of LFPB, including discount rate, mortality, lapses, and expenses. DPL is amortized and recognized as premium revenue in proportion to insurance in force for life insurance contracts and expected future benefit payments for annuity contracts. Interest is accreted on the balance of DPL using the discount rate determined at contract issuance. The Company reviews and updates its estimates of cash flows for DPL at the same time as the estimates of cash flows for the liability for future policy benefits. When cash flows are updated, the updated estimates are used to recalculate DPL at contract issuance. The recalculated DPL as of the beginning of the current reporting period is compared to the carrying amount of DPL as of the beginning of the current reporting period, and any difference is recognized as either a charge or credit to Net premiums and contract charges earned presented in the Consolidated Statements of Operations and Comprehensive Income (Loss). DPL is recognized as a component of the Investment contract and future policy benefit reserves presented in the Consolidated Balance Sheets. Market Risk Benefits MRBs are contracts or contract features that both provide protection to the contract holder from other-than-nominal capital market risk and expose the Company to other-than-nominal capital market risk. MRBs include guaranteed minimum death benefits on variable annuity products. MRBs are measured at fair value using a non-option-based valuation model based on current net amounts at risk, market data, Company experience, and other factors. Changes in fair value of MRBs are recognized as a component of Benefits, claims and settlement expenses presented in the Consolidated Statements of Operations and Comprehensive Income (Loss) each period with the exception of the portion of the change in fair value due to a change in the instrument-specific credit risk, which is recognized in other comprehensive income. MRBs are recognized as a component of Policyholders' account balances reserves presented in the Consolidated Balance Sheets. Deferred Policy Acquisition Costs and Deferred Sales Inducements DAC are costs that are incremental and directly related to the successful acquisition of new or renewal insurance contracts. Such costs include the incremental direct costs of contract acquisition, such as sales commissions; the portion of employees' total compensation and payroll-related fringe benefits related directly to time spent performing acquisition activities, such as underwriting, issuing, and processing policies for contracts that have actually been acquired; and other costs related directly to acquisition activities that would not have been incurred if the contract had not been acquired. Contracts are grouped by contract type and issue year into cohorts consistent with the grouping used in estimating the associated liability. DAC is amortized on a constant level basis for the grouped contracts over the expected term of the related contracts to approximate straight-line amortization. For all life insurance products, the constant level basis used is face amount in force. For all deferred annuity products, the constant level basis used is the deposit amount in force. The constant level bases used for amortization are projected using mortality and lapse assumptions that are based on the Company's experience, industry data, and other factors and are consistent with those used for LFPB. If those projected assumptions change in future periods, they will be reflected in the cohort level amortization basis at that time. Unexpected terminations, due to mortality and lapse experience higher than expected, are recognized in the current period as a reduction of the capitalized balances. Amortization of DAC is recognized as DAC amortization expense presented in the Consolidated Statements of Operations and Comprehensive Income (Loss). The DAC balance is reduced for actual experience in excess of expected experience. Changes in future estimates are recognized prospectively over the remaining expected contract term. Deferred sales inducements (DSIs) are contract features that are intended to attract new customers or to persuade existing customers to keep their current policy. DSIs may be deferred if the Company can demonstrate that the deferred sales inducement amounts are both incremental to the amounts Company credits on similar contracts without sales inducements and the amounts are higher than the contract's expected ongoing crediting rates for periods after the inducement. Day-one bonuses and persistency bonuses generally meet the criteria to be deferred. DSIs are amortized using the same methodology and assumptions used to amortize DAC.

Investments, Debt and Equity Securities [Abstract]
Investments	NOTE 2 - Investments Net Investment Income The components of net investment income for the following periods were as follows: ($ in millions) Three Months Ended 2023 2022 Fixed maturity securities $ 67.7 $ 58.6 Equity securities 2.7 1.3 Limited partnership interests 4.4 13.0 Short-term and other investments 3.5 2.7 Investment expenses (3.6) (2.6) Net investment income - investment portfolio 74.7 73.0 Investment income - deposit asset on reinsurance 25.7 24.9 Total net investment income $ 100.4 $ 97.9 Net Investment Losses Net investment gains (losses) for the following periods were as follows: ($ in millions) Three Months Ended 2023 2022 Fixed maturity securities $ (2.4) $ (2.3) Equity securities (1.0) (15.5) Short-term investments and other (0.5) 2.3 Net investment losses $ (3.9) $ (15.5) The Company, from time to time, sells fixed maturity securities subsequent to the reporting date that were considered temporarily impaired at such reporting date. Such sales are due to issuer-specific events occurring subsequent to the reporting date that result in a change in the Company's intent to sell a fixed maturity security. The types of events that may result in a sale include significant changes in the economic facts and circumstances related to the invested asset, significant unforeseen changes in liquidity needs, or changes in the Company's investment strategy. Net Investment Losses by Transaction Type The breakdown of net investment gains (losses) by transaction type for the following periods were as follows: ($ in millions) Three Months Ended 2023 2022 Credit loss impairments $ — $ (0.9) Intent-to-sell impairments — (0.9) Total impairments — (1.8) Sales and other, net (2.4) 1.1 Change in fair value - equity securities (1.0) (17.1) Change in fair value and gains (losses) realized on settlements - derivatives (0.5) 2.3 Net investment losses $ (3.9) $ (15.5) Allowance for Credit Loss Impairments on Fixed Maturity Securities The following table presents changes in the allowance for credit loss impairments on fixed maturity securities classified as available for sale for the category of other asset-backed securities (no other categories of fixed maturity securities have an allowance for credit loss impairments): ($ in millions) Three Months Ended 2023 2022 Beginning balance $ 1.2 $ 7.7 Credit losses on fixed maturity securities for which credit losses were not previously reported — — Net increase related to credit losses previously reported — 0.9 Reduction of credit allowances related to sales — — Write-offs — (0.3) Ending balance $ 1.2 $ 8.3 Fixed Maturity Securities The Company's investment portfolio is comprised primarily of fixed maturity securities. Amortized cost, net, gross unrealized investment gains (losses) and fair values of all fixed maturity securities in the portfolio were as follows: ($ in millions) Amortized Gross Unrealized Gross Unrealized Fair March 31, 2023 Fixed maturity securities U.S. Government and federally sponsored agency obligations: (1) Mortgage-backed securities $ 637.6 $ 2.0 $ 55.6 $ 584.0 Other, including U.S. Treasury securities 424.4 1.2 60.6 365.0 Municipal bonds 1,363.0 26.3 98.5 1,290.8 Foreign government bonds 34.1 — 1.5 32.6 Corporate bonds 2,155.4 17.2 229.1 1,943.5 Other asset-backed securities 1,188.8 2.9 57.6 1,134.1 Totals $ 5,803.3 $ 49.6 $ 502.9 $ 5,350.0 December 31, 2022 Fixed maturity securities U.S. Government and federally sponsored agency obligations: (1) Mortgage-backed securities $ 638.2 $ 1.3 $ 69.1 $ 570.4 Other, including U.S. Treasury securities 410.0 0.5 67.8 342.7 Municipal bonds 1,380.9 16.9 128.1 1,269.7 Foreign government bonds 35.1 — 1.6 33.5 Corporate bonds 2,161.2 12.7 272.2 1,901.7 Other asset-backed securities 1,131.5 3.6 68.1 1,067.0 Totals $ 5,756.9 $ 35.0 $ 606.9 $ 5,185.0 (1) Fair value includes securities issued by Federal National Mortgage Association (FNMA) of $341.3 million and $330.8 million; Federal Home Loan Mortgage Corporation (FHLMC) of $279.3 million and $273.3 million; and Government National Mortgage Association (GNMA) of $86.8 million and $86.2 million as of March 31, 2023 and December 31, 2022, respectively. The following table presents the fair value and gross unrealized losses for fixed maturity securities in an unrealized loss position as of March 31, 2023 and December 31, 2022, respectively. The Company views the decrease in fair value of all of the fixed maturity securities with unrealized losses as of March 31, 2023 — which was driven largely by increasing interest rates, spread widening, financial market illiquidity and/or market volatility from the date of acquisition — as temporary. As of March 31, 2023, the Company has not made the decision to sell and it is not more likely than not the Company will be required to sell the fixed maturity securities with unrealized losses before an anticipated recovery in value. There has been a significant increase in interest rates since January 1, 2022 driven mostly by increases in U.S. Treasury rates, though credit spreads also widened. As of March 31, 2023, the 10-year U.S. Treasury yield increased 196 basis points since January 2022, rising from 1.51% as of January 1, 2022 to 3.47% as of March 31, 2023. Additionally, credit spreads widened during the same time period, with investment grade and high yield wider by 46 and 172 basis points, respectively. These upward movements in rates caused market yields in the Company's investment portfolios to rise sharply, with downward pressure on prices. As of March 31, 2023, investment grade and high yield total returns were down 12.8% and 8.0%, respectively, since January 1, 2022. As of March 31, 2023, the Bloomberg Barclays Index Yield-to-Worst for Investment Grade rose 2.84% since January 1, 2022, ending at 5.2%, while the High Yield Index rose 4.31% to 8.5% since January 1, 2022. The Company's investment portfolios generated sizable unrealized losses as a result of sharp increases in interest rates. Therefore, it was determined that the unrealized losses on the fixed maturity securities presented in the table below were not indicative of any credit loss impairments as of March 31, 2023.

With respect to fixed maturity securities involving securitized financial assets, the underlying collateral cash flows were stress tested to determine there was no adverse change in the present value of cash flows below the net amortized cost basis. Maturities of Fixed Maturity Securities The following table presents the distribution of the Company’s fixed maturity securities portfolio by estimated expected maturity. Estimated expected maturities differ from contractual maturities, reflecting assumptions regarding borrowers' utilization of the right to call or prepay obligations with or without call or prepayment penalties. For structured securities, estimated expected maturities consider broker-dealer survey prepayment assumptions and are verified for consistency with the interest rate and economic environments.

Principal factors influencing carrying amount appreciation or depreciation include operating performance, comparable public company earnings multiples, capitalization rates and the economic environment. The Company recognizes an impairment loss for EMA limited partnership interests when evidence demonstrates that the loss is other than temporary. Evidence of a loss in value that is other than temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment. The carrying amounts of EMA limited partnership interests were as follows: ($ in millions) March 31, 2023 December 31, 2022 Commercial mortgage loan funds $ 623.7 $ 593.6 Private equity funds 77.7 76.3 Infrastructure equity funds 73.2 72.0 Real estate equity funds 87.7 71.3 Infrastructure debt funds 62.6 60.0 Other funds (1) 120.5 110.5 Total $ 1,045.4 $ 983.7 (1) Other funds consist primarily of limited partnership interests in corporate mezzanine, venture capital and private credit funds. Offsetting of Assets and Liabilities The Company's derivatives are subject to enforceable master netting arrangements. Collateral support agreements associated with each master netting arrangement provides that the Company will receive or pledge financial collateral in the event minimum thresholds have been reached. The Company’s reverse repurchase agreements are also subject to enforceable master netting arrangements but there was no offsetting in their presentation in the Company’s Consolidated Balance Sheets. Information regarding the Company's derivatives is contained in Part II - Item 8, Note 5 in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. The following table presents instruments that were subject to a master netting arrangement for the Company. ($ in millions) Gross Net Amounts Gross Amounts Not Offset Gross Financial Cash Net March 31, 2023 Asset derivatives: Free-standing derivatives $ 9.2 $ — $ 9.2 $ — $ 8.3 $ 0.9 December 31, 2022 Asset derivatives: Free-standing derivatives $ 6.8 $ — $ 6.8 $ — $ 5.9 $ 0.9 Reverse Repurchase Agreements In connection with reverse repurchase agreements, the Company transfers primarily U.S. government, government agency and corporate securities and receives cash. For reverse repurchase agreements, the Company receives cash in an amount equal to at least 95% of the fair value of the securities transferred, and the agreements with third parties contain contractual provisions to allow for additional collateral to be obtained when necessary. The Company accounts for reverse repurchase agreements as secured borrowings. The securities transferred under reverse repurchase agreements are included in Fixed maturity securities with the obligation to repurchase those securities reported in Other liabilities on the Company's Consolidated Balance Sheets. The fair value of the securities transferred wa s $74.7 million as of March 31, 2023 and $73.3 million as of December 31, 2022. The obligation for securities sold under reverse repurchase agreements was a net amount of $70.2 million as of March 31, 2023 and December 31, 2022. Deposits As of March 31, 2023 and December 31, 2022, fixed maturity securities with a fair value of $29.0 million and $28.6 million, respectively, were on deposit with governmental agencies as required by law in various states for which the insurance subsidiaries of HMEC conduct business. In addition, as of March 31, 2023 and December 31, 2022, fixed maturity securities with a fair value of $948.1 million and $860.4 million, respectively, were on deposit with the Federal Home Loan Bank of Chicago (FHLB) as collateral for amounts subject to funding agreements, advances and borrowings which were equal to $869.5 million as of March 31, 2023 and $792.5 million as of December 31, 2022. The deposited securities are reported as Fixed maturity securities on the Company’s Consolidated Balance Sheets.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company is required to disclose estimated fair values for certain financial and nonfinancial assets and liabilities. Fair values of the Company’s insurance contracts other than annuity contracts (which are investment contracts) and EMA limited partnership interests are not required to be disclosed. However, the estimated fair values of liabilities under all insurance contracts are taken into consideration in the Company’s overall management of interest rate risk through appropriate matching of investment maturities with amounts due under insurance contracts. Information regarding the three-level fair value hierarchy presented below and the valuation methodologies utilized by the Company to estimate fair values at each reporting date is included in Part II - Item 8, Note 4 of the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Financial Instruments Measured and Carried at Fair Value on a Recurring Basis The following table presents the Company's fair value hierarchy for financial assets and financial liabilities measured and carried at fair value on a recurring basis. During the three months ended March 31, 2023 and 2022, there were no transfers between Level 1 and Level 2. As of March 31, 2023, Level 3 invested assets comprised 8.0% of the Company’s total investment portfolio at fair value.

(2) Includes U.S. Government and federally sponsored agency obligations for mortgage-backed securities and other asset-backed securities. (3) Transfers into and out of Level 3 during the three months ended March 31, 2023 and 2022 were related to changes in the primary pricing source and changes in observability of external information used in determining fair value. The Company's policy is to recognize transfers into and out of the levels as having occurred at the end of the reporting period in which the transfers were determined. For the three months ended March 31, 2023, the Company had no net investment losses and $1.0 million of net investment losses for the three months ended March 31, 2022, that were included in net income and were primarily attributable to credit loss impairments for Level 3 financial assets. For the three months ended March 31, 2023, the Company had net investment losses of $0.2 million and $5.2 million of net investment gains for the three months ended March 31, 2022, that were included in net income and were attributable to changes in the fair value of Level 3 financial liabilities. Quantitative Information about Level 3 Fair Value Measurements The following table provides quantitative information about the significant unobservable inputs for recurring fair value measurements categorized within Level 3.

(5) Determined as a percentage of the risk-free rate. The valuation techniques and significant unobservable inputs used in the fair value measurement for financial assets and financial liabilities classified as Level 3 are subject to the control processes as described in Part II - Item 8, Note 4 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Generally, valuation techniques for fixed maturity securities include spread pricing, matrix pricing and discounted cash flow methodologies; include inputs such as quoted prices for identical or similar securities that are less liquid; and are based on lower levels of trading activity than securities classified as Level 2. The valuation techniques and significant unobservable inputs used in the fair value measurement for equity securities classified as Level 3 use similar valuation techniques and significant unobservable inputs as those used for fixed maturity securities. The sensitivity of the estimated fair values to changes in the significant unobservable inputs for fixed maturity and equity securities included in Level 3 include: benchmark yield, liquidity premium, estimated cash flows, prepayment and default speeds, spreads, weighted average life and credit rating. Significant spread widening in isolation will adversely impact the overall valuation, while significant tightening will lead to substantial valuation increases. Significant increases (decreases) in illiquidity premiums in isolation will result in substantially lower (higher) valuations. Significant increases (decreases) in expected default rates in isolation will result in substantially lower (higher) valuations. Financial Instruments Not Carried at Fair Value The Company has various other financial assets and financial liabilities used in the normal course of business that are not carried at fair value, but for which fair value disclosure is required.

The assets that support variable contracts are measured at fair value and are reported as separate account assets on the Consolidated Balance Sheets. An equivalent amount is reported as separate account liabilities. MRB assets and liabilities for minimum guarantees are valued and presented separately from separate account assets and separate account liabilities. MRBs are discussed further in the market risk benefits section of this Note to the Consolidated Financial Statements. Policy charges assessed against the policyholders for mortality, administration and other services are included in the life premiums and contract charges line item on the Consolidated Statements of Operations and Comprehensive Income (Loss).

Segment Reporting [Abstract]
Segment Information	Segment Information The Company conducts and manages its business in four reporting segments. The three operating segments, representing the major lines of business, are: (1) Property & Casualty (primarily personal lines of auto and property insurance products), (2) Life & Retirement (primarily tax-qualified fixed and variable annuities as well as life insurance products), and (3) Supplemental & Group Benefits (primarily cancer, heart, hospital, supplemental disability, accident, short-term and long-term group disability, and group term life coverages). The Company does not allocate the impact of corporate-level transactions to these operating segments, consistent with the basis for management's evaluation of the results of those segments, but classifies those items in the fourth reporting segment, Corporate & Other. In addition to ongoing transactions such as corporate debt service, net investment gains (losses) and certain public company expenses, such items in Corporate & Other have also included corporate debt retirement costs, when applicable. Summarized financial information for these segments is as follows: ($ in millions) Three Months Ended 2023 2022 Net premiums and contract charges earned Property & Casualty $ 152.4 $ 150.2 Life & Retirement 37.7 35.8 Supplemental & Group Benefits 65.8 69.8 Total $ 255.9 $ 255.8 Net investment income Property & Casualty $ 4.0 $ 7.2 Life & Retirement 87.9 84.2 Supplemental & Group Benefits 9.1 7.1 Corporate & Other — — Intersegment eliminations (0.6) (0.6) Total $ 100.4 $ 97.9 Net income (loss) Property & Casualty $ (11.6) $ 8.5 Life & Retirement 14.0 15.6 Supplemental & Group Benefits 14.0 13.2 Corporate & Other (9.8) (17.0) Total $ 6.6 $ 20.3 ($ in millions) March 31, 2023 December 31, 2022 Assets Property & Casualty $ 1,077.0 $ 1,083.8 Life & Retirement 11,085.1 10,754.5 Supplemental & Group Benefits 1,377.1 1,359.3 Corporate & Other 169.0 173.4 Intersegment eliminations (54.3) (64.9) Total $ 13,653.9 $ 13,306.1

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Contingencies and Commitments Lawsuits and Legal Proceedings Companies in the insurance industry have been subject to substantial litigation resulting from claims, disputes and other matters. For instance, they have faced expensive claims, including class action lawsuits, alleging, among other things, improper sales practices and improper claims settlement procedures. Negotiated settlements of certain such actions have had a material adverse effect on many insurance companies. At the time of issuance of this Quarterly Report on Form 10-Q, the Company does not have pending litigation from which there is a reasonable possibility of material loss. Assessments for Insolvencies of Unaffiliated Insurance Companies The Company is contingently liable for possible assessments under regulatory requirements pertaining to potential insolvencies of unaffiliated insurance companies. Liabilities, which are established based upon regulatory guidance, have generally been insignificant. Investment Commitments The Company has outstanding commitments to fund investments primarily in limited partnership interests. Such unfunded commitments were $599.4 million and $704.2 million as of March 31, 2023 and December 31, 2022, respectively.

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, 2022. The results of operations for the three months ended March 31, 2023 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, 2022. 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, 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 expense reserves, valuation of liabilities for group benefits unpaid claims and claim expense reserves, valuation of future policy benefit reserves and policyholders' account balances and valuation of long-duration insurance contracts under the new accounting guidance in ASU 2018-12.
Adoption of New Accounting Standards / Significant Accounting Policies	Adoption of New Accounting Standards Accounting for Long-Duration Insurance Contracts In August 2018, the FASB issued ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, as clarified and amended by (i) ASU 2019-09, Financial Services - Insurance (Topic 944): Effective Date, and (ii) ASU 2020-11, Financial Services - Insurance (Topic 944): Effective Date and Early Application (collectively referred to herein as ASU 2018-12). ASU 2018-12 changed existing recognition, measurement, presentation, and disclosure requirements for long-duration contracts. ASU 2018-12 includes: (1) a requirement to review and, if there is a change, update cash flow assumptions used to measure the liability for future policy benefits (LFPB) at least annually, and to update the discount rate assumption quarterly, (2) a requirement to account for market risk benefits (MRBs) at fair value, (3) simplified amortization for deferred policy acquisition costs (DAC), and (4) enhanced financial statement presentation and disclosures. ASU 2018-12 became effective for the Company for interim and annual periods beginning after December 15, 2022. The Company adopted ASU 2018-12 for LFPB and DAC on a modified retrospective basis such that those balances were adjusted to conform to ASU 2018-12 on January 1, 2021. The Company adopted ASU 2018-12 for MRBs on a full retrospective basis, using hindsight where necessary. For variable annuities, actuarial assumptions (mortality, lapse, and premium payment patterns) used to measure MRBs were unobservable for years prior to 2006 and thus, hindsight was used to determine relevant assumptions for transition purposes. The factors used in applying hindsight included internal experience studies, the historical economic environment, actual performance of the business, and relevant industry information. For LFPB, the net transition adjustment is related to the difference in the discount rate used pre-transition and the discount rate at January 1, 2021. At transition, the Company had several instances, at the cohort level, where net premiums exceeded gross premiums which were recorded as an adjustment to retained earnings. For DAC, the Company removed shadow adjustments previously recorded in accumulated other comprehensive income (loss) (i.e., AOCI) for the impact of net unrealized investment gains (losses) that were included in the pre-ASU 2018-12 expected gross profits amortization calculation as of the transition date. For MRBs, the transition adjustment to AOCI relates to the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date. The remaining difference between the fair value and carrying amount of MRBs at transition, excluding the amounts recorded in AOCI, was recorded as an adjustment to retained earnings as of the transition date. While the requirements of ASU 2018-12 represent a significant change from legacy GAAP, the adoption of ASU 2018-12 did not impact cash flows on the Company’s policies, or the underlying economics of the Company’s business. The Company's insurance subsidiaries' risk-based capital amounts and ratios, and regulatory dividends are not impacted as the National Association of Insurance Commissioners (NAIC) rejected ASU 2018-12. See Note 11 for summarization of the effects of adopting ASU 2018-12 on the Company's 2022 Consolidated Financial Statements. Significant Accounting Policies The following significant accounting policy has been added to reflect the Company's adoption of ASU 2018-12 as described above. Liability for Future Policy Benefits LFPB, which is the present value of estimated future policy benefits to be paid to or on behalf of policyholders and certain related expenses less the present value of estimated future net premiums to be collected from policyholders, is accrued as premium revenue. The liability is estimated using current assumptions that include discount rate, mortality, lapses, and expenses. These current assumptions are based on judgments that consider the Company's historical experience, industry data, and other factors. For traditional, limited-payment and supplemental health contracts, such contracts are grouped into cohorts by contract type and issue year. The liability is adjusted for differences between actual and expected experience. With the exception of the expense assumption, the Company reviews its historical and future cash flow assumptions at least annually and updates the net premium ratio used to calculate the liability each time the assumptions are changed. The Company has elected to use expense assumptions that are locked-in at contract inception and are not subsequently reviewed or updated. At least annually, the Company updates its estimate of cash flows expected over the entire life of a group of contracts using actual historical experience and current future cash flow assumptions. These updated cash flows are used to calculate the revised net premiums and net premium ratio, which are used to derive an updated LFPB as of the beginning of the current reporting period, discounted at the original contract issuance discount rate. This amount is then compared to the carrying amount of the liability as of that same date, before updating cash flow assumptions, to determine the current period change in liability estimate. This current period change in liability estimate is the liability remeasurement gain or loss. The impact of updated cash flow assumptions as well as the periodic liability remeasurement gain or loss is recognized as Benefits, claims and settlement expenses in the Consolidated Statements of Operations and Comprehensive Income (Loss). In subsequent periods, the revised net premiums are used to measure LFPB, subject to future revisions. For traditional and limited-payment contracts, a standard discount rate is used to measure the liabilities that is equivalent to the yield from an A-rated bond. The discount rate assumption is updated quarterly and used to remeasure the liability at the reporting date, with the resulting change reflected in other comprehensive income. For liability cash flows that are projected beyond the duration of market-observable A- rated bond, the Company uses the last market-observable yield level, and uses linear interpolation to determine yield assumptions for durations that do not have market-observable yields. Deferred Profit Liability For limited-payment products, gross premiums received in excess of net premiums are deferred at initial recognition as a DPL. Gross premiums are measured using assumptions consistent with those used in the measurement of LFPB, including discount rate, mortality, lapses, and expenses. DPL is amortized and recognized as premium revenue in proportion to insurance in force for life insurance contracts and expected future benefit payments for annuity contracts. Interest is accreted on the balance of DPL using the discount rate determined at contract issuance. The Company reviews and updates its estimates of cash flows for DPL at the same time as the estimates of cash flows for the liability for future policy benefits. When cash flows are updated, the updated estimates are used to recalculate DPL at contract issuance. The recalculated DPL as of the beginning of the current reporting period is compared to the carrying amount of DPL as of the beginning of the current reporting period, and any difference is recognized as either a charge or credit to Net premiums and contract charges earned presented in the Consolidated Statements of Operations and Comprehensive Income (Loss). DPL is recognized as a component of the Investment contract and future policy benefit reserves presented in the Consolidated Balance Sheets. Market Risk Benefits MRBs are contracts or contract features that both provide protection to the contract holder from other-than-nominal capital market risk and expose the Company to other-than-nominal capital market risk. MRBs include guaranteed minimum death benefits on variable annuity products. MRBs are measured at fair value using a non-option-based valuation model based on current net amounts at risk, market data, Company experience, and other factors. Changes in fair value of MRBs are recognized as a component of Benefits, claims and settlement expenses presented in the Consolidated Statements of Operations and Comprehensive Income (Loss) each period with the exception of the portion of the change in fair value due to a change in the instrument-specific credit risk, which is recognized in other comprehensive income. MRBs are recognized as a component of Policyholders' account balances reserves presented in the Consolidated Balance Sheets. Deferred Policy Acquisition Costs and Deferred Sales Inducements DAC are costs that are incremental and directly related to the successful acquisition of new or renewal insurance contracts. Such costs include the incremental direct costs of contract acquisition, such as sales commissions; the portion of employees' total compensation and payroll-related fringe benefits related directly to time spent performing acquisition activities, such as underwriting, issuing, and processing policies for contracts that have actually been acquired; and other costs related directly to acquisition activities that would not have been incurred if the contract had not been acquired. Contracts are grouped by contract type and issue year into cohorts consistent with the grouping used in estimating the associated liability. DAC is amortized on a constant level basis for the grouped contracts over the expected term of the related contracts to approximate straight-line amortization. For all life insurance products, the constant level basis used is face amount in force. For all deferred annuity products, the constant level basis used is the deposit amount in force. The constant level bases used for amortization are projected using mortality and lapse assumptions that are based on the Company's experience, industry data, and other factors and are consistent with those used for LFPB. If those projected assumptions change in future periods, they will be reflected in the cohort level amortization basis at that time. Unexpected terminations, due to mortality and lapse experience higher than expected, are recognized in the current period as a reduction of the capitalized balances. Amortization of DAC is recognized as DAC amortization expense presented in the Consolidated Statements of Operations and Comprehensive Income (Loss). The DAC balance is reduced for actual experience in excess of expected experience. Changes in future estimates are recognized prospectively over the remaining expected contract term. Deferred sales inducements (DSIs) are contract features that are intended to attract new customers or to persuade existing customers to keep their current policy. DSIs may be deferred if the Company can demonstrate that the deferred sales inducement amounts are both incremental to the amounts Company credits on similar contracts without sales inducements and the amounts are higher than the contract's expected ongoing crediting rates for periods after the inducement. Day-one bonuses and persistency bonuses generally meet the criteria to be deferred. DSIs are amortized using the same methodology and assumptions used to amortize DAC.
