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) whether they engage with Horace Mann directly or through their district/employer. The Company operates under four reporting segments: (1) Property & Casualty, (2) Life & Retirement, (3) Supplemental & Group Benefits and (4) Corporate & Other. Basis of Presentation The accompanying audited consolidated financial statements have been prepared in accordance 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). 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 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, 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 certain investment contracts and policy reserves, valuation of long-duration contracts under the new accounting guidance in ASU 2018-12 and valuation of assets acquired and liabilities assumed under purchase accounting. Investments Fixed Maturity Securities The Company invests predominantly in fixed maturity securities. Fixed maturity securities include bonds, asset-backed securities (ABS), mortgage-backed securities (MBS), other structured securities and redeemable preferred stocks. MBS includes residential and commercial mortgage-backed securities. Fixed maturity securities, which may be sold prior to their contractual maturity, are designated as available for sale (AFS) and are carried at fair value of which a portion represent securities that are hard-to-value. See Note 4 – Fair Value of Financial Instruments – Investments for a detailed description of how the Company estimates fair value for its fixed maturity securities portfolio including hard-to-value securities. An adjustment for net unrealized investment gains (losses) on all fixed maturity securities available for sale and carried at fair value, is recognized as a separate component of accumulated other comprehensive income (loss) (i.e., AOCI) within shareholders’ equity, net of applicable deferred taxes and the related impact on deferred policy acquisition costs (DAC) associated with annuity contracts and life insurance products with account values that would have occurred if the securities had been sold at their aggregate fair value and the proceeds reinvested at current yields. The Company excludes accrued interest receivable from the amortized cost basis of its AFS fixed maturity securities. Equity Securities Equity securities primarily include common stocks, exchange traded and mutual funds and non-redeemable preferred stocks. Certain exchange traded and mutual funds have fixed maturity securities as their underlying investments. Equity securities are carried at fair value and have readily determinable fair values. Limited Partnership Interests Investments in limited partnership interests are accounted for using the equity method of accounting (EMA) and include interests in commercial mortgage loan funds, private equity funds, infrastructure equity funds, real estate equity funds, infrastructure debt funds and other funds. Short-Term and Other Investments Short-term investments, including money market funds, commercial paper, U.S. Treasury bills and other short-term investments, are carried at fair value. Other investments primarily consist of policy loans, Federal Home Loan Bank of Chicago (FHLB) common stock, mortgage loans and derivatives. Policy loans are carried at unpaid principal balances. FHLB common stock is carried at cost. Mortgage loans are carried at amortized cost, net, which represent the amount expected to be collected. Derivatives are carried at fair value. Variable Interest Entities (VIEs) The Company invests in fixed maturity securities and alternative investment funds that could qualify as variable interests in VIEs, including corporate securities, ABS and MBS. Such variable interests in VIEs have been reviewed and the Company determined that those VIEs are not subject to consolidation as the Company is not the primary beneficiary because it does not have the power to direct the activities that most significantly impact those VIEs' economic performance. Net Investment Income Net investment income primarily consists of interest, dividends and income from limited partnership interests. Interest is recognized on an accrual basis using the effective yield method and dividends are recorded at the ex-dividend date. ABS and MBS interest income is determined considering estimated pay-downs, including prepayments, obtained from third-party data sources and internal estimates. Actual prepayment experience is periodically reviewed, and effective yields are recalculated when differences arise between the prepayments originally anticipated and the actual prepayments received and currently anticipated. For ABS and MBS of high credit quality with fixed interest rates, the effective yield is recalculated on a retrospective basis. For all others, the effective yield is generally recalculated on a prospective basis. Net investment income for AFS fixed maturity securities includes the impact of accreting the credit loss allowance for the time value of money. Accrual of income is suspended for fixed maturity securities when the timing and amount of cash flows expected to be received is not reasonably estimable. Accrual of income is suspended for commercial mortgage loans that are in default or when full and timely collection of principal and interest payments is not probable. Accrued investment income receivables are monitored for recoverability and when not expected to be collected, are written-off through net investment income. Cash receipts on investments on non-accrual status are generally recorded as a reduction of amortized cost or principal. Income from limited partnership interests is recognized based upon the changes in fair value of the investee’s equity primarily determined using its net asset value and is generally recognized on a three month delay due to the availability of the related financial statements of the investee. The Company reports accrued investment income separately from AFS fixed maturity securities and has elected not to measure an allowance for credit losses for accrued investment income. Accrued investment income is written-off and recognized as a net investment loss at the time the issuer of the security defaults or is expected to default on payments. Net Investment Gains (Losses) Net investment gains (losses) include gains and losses on investment sales, changes in the credit loss allowances related to fixed maturity securities and mortgage loans, impairments, valuation changes of equity securities and periodic changes in fair value and settlements of derivatives. Net investment gains (losses) on investment sales are determined on a specific identification basis and are net of credit losses already recognized through an allowance. Credit Loss Impairments for Fixed Maturity Securities For AFS fixed maturity securities, the difference between amortized cost, net of a credit loss allowance (i.e., amortized cost, net) and fair value, net of certain other items and deferred income taxes is reported as a component of AOCI on the Consolidated Balance Sheets and is not reflected in the operating results of any period until reclassified to net income upon the consummation of a transaction with an unrelated third party or when a credit loss allowance is recorded. The Company has a comprehensive portfolio monitoring process to evaluate fixed maturity securities (at the cusip/issuer level) on a quarterly basis that may require a credit loss allowance. These reviews, in conjunction with the Company's investment managers’ monthly credit reports and relevant factors such as (1) the financial condition and near-term prospects of the issuer; (2) the Company’s intent to sell a security or whether it is more likely than not that the Company will be required to sell a security before the anticipated recovery in value; (3) the market leadership of the issuer; (4) the debt ratings of the issuer; and (5) the cash flows and liquidity of the issuer or the underlying cash flows for ABS and MBS, are all considered in the impairment assessment. For each fixed maturity security in an unrealized loss position, the Company assesses whether management with the appropriate authority has made the decision to sell or whether it is more likely than not that the Company will be required to sell the security before the anticipated recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If a security meets either of these criteria, any existing credit loss allowance would be written-off against the amortized cost basis of the asset along with any remaining unrealized losses, with the incremental losses recorded as a net investment loss. If the Company has not made the decision to sell the fixed maturity security and it is not more likely than not that the Company will be required to sell the fixed maturity security before the anticipated recovery of its amortized cost basis, the Company evaluates whether it expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. The Company estimates the anticipated recovery value based on the best estimate of future cash flows considering past events, current conditions and reasonable and supportable forecasts. The estimated future cash flows are discounted at the security’s current effective rate and are compared to the amortized cost basis of the security. The determination of cash flow estimates is inherently subjective, and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security are considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, the remaining payment terms of the security, prepayment speeds, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, origination vintage year, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third-party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, sector credit ratings, financial condition of the bond insurer for insured fixed maturity securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate the anticipated recovery value if the Company determines that the security is dependent on the liquidation of collateral for ultimate settlement. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed maturity security, a credit loss allowance is recorded as a net investment loss for the shortfall in expected cash flows; however, the amortized cost basis, net of the credit loss allowance, may not be lower than the fair value of the security. The portion of the unrealized loss related to factors other than credit remains classified in AOCI. If the Company determines that the fixed maturity security does not have sufficient cash flows or other information to estimate a recovery value for the security, the Company may conclude that the entire decline in fair value is deemed to be credit related and the loss is recognized as a net investment loss. When a security is sold or otherwise disposed or the security is deemed uncollectible and written-off, the Company reverses amounts previously recognized in the credit loss allowance through net investment gains (losses). Recoveries after write-offs are recognized when received. Deferred Policy Acquisition Costs The Company's DAC by reporting segment was as follows: ($ in millions) December 31, 2022 2021 Property & Casualty $ 24.5 $ 24.4 Life & Retirement 403.5 219.4 Supplemental & Group Benefits 5.1 4.2 Total $ 433.1 $ 248.0 DAC consists of commissions, policy issuance and other costs which are incremental and directly related to the successful acquisition of new or renewal business, which are deferred and amortized on a basis consistent with the type of insurance coverage. For property and casualty risks, DAC is amortized over the terms of the insurance policies (6 or 12 months). For all annuity contracts, DAC is amortized over 20 years in proportion to estimated gross profits. DAC is amortized in proportion to estimated gross profits over 20 years for certain life insurance products with account values and over 30 years for indexed universal life (IUL) products. For other individual life contracts, DAC is amortized in proportion to anticipated premiums over the terms of the insurance policies (10, 15, 20, 30 years). For supplemental and group benefit policies, DAC is amortized in proportion to anticipated premiums over the terms of the insurance policies (approximately 6 years, based on an estimated average duration across all supplemental and group benefit products). The Company periodically reviews the assumptions and estimates used in DAC and also periodically reviews its estimations of gross profits, a process sometimes referred to as "unlocking". The most significant assumptions that are involved in the estimation of annuity gross profits include interest rate spreads, future financial market performance, business surrender/lapse rates, expenses and the impact of net investment gains (losses) on fixed maturity and equity securities. For the variable deposit portion of retirement, the Company amortizes DAC utilizing a future financial market performance assumption of a gross 8% reversion to the mean approach with a 200 basis point corridor around the mean during the reversion period, representing a cap and a floor on the Company's long-term assumption. The Company's practice with regard to future financial market performance assumes that long-term appreciation in the financial markets is not changed by short-term market fluctuations, but is only changed when sustained deviations are experienced. The Company monitors these fluctuations and only changes the assumption when long-term expectations change. The most significant assumptions that are involved in the estimation of life insurance gross profits include interest rates expected to be received on investments, business persistency, and mortality. Conversions from term to permanent insurance cause an immediate write down of the associated DAC. The most significant assumptions that are involved in the estimation of supplemental gross profits include morbidity, persistency, expenses and interest rates expected to be received on investments. When a supplemental policy lapses, there is an immediate write down of the associated DAC. Annually, the Company performs a gross premium valuation (GPV) on life insurance policies to assess whether a loss recognition event has occurred. This involves discounting expected future benefits and expenses less expected future premiums. To the extent that this amount is greater than the liability for future benefits less the DAC asset, in aggregate for the life insurance block, a loss would be recognized by first writing-off the DAC asset and then increasing the liability. In the event actual experience differs significantly from assumptions or assumptions are significantly revised, the Company may be required to recognize a material charge or credit to current period DAC amortization expense for the period in which the adjustment is made. The Company recognized the following adjustments to DAC amortization expense as a result of evaluating actual experience and prospective assumptions (i.e., the impact of unlocking): ($ in millions) Year Ended December 31, 2022 2021 2020 (Decrease) increase to DAC amortization expense: Life & Retirement $ 5.1 $ (1.5) $ (2.1) Supplemental & Group Benefits — — — Total $ 5.1 $ (1.5) $ (2.1) DAC for annuity contracts and life insurance products with account values are adjusted for the impact on estimated future gross profits as if net unrealized investment gains (losses) on fixed maturity securities had been realized at the reporting date. This adjustment increased DAC by $118.0 million as of December 31, 2022 and reduced DAC by $71.9 million and $90.5 million as of December 31, 2021 and 2020, respectively. The after tax impact of this adjustment is included in AOCI (along with net unrealized investment gains (losses) on fixed maturity securities) within shareholders' equity. DAC is reviewed for recoverability from future income, including net investment income, and costs that are deemed unrecoverable are expensed in the period in which the determination is made. No such costs were deemed unrecoverable during the years ended December 31, 2022, 2021 and 2020. Intangible Assets, net The value of business acquired (VOBA) associated with the acquisitions of NTA Life Enterprises, LLC (NTA) and Madison National Life Insurance Company, Inc. (Madison National) represents the difference between the fair value of insurance contracts and insurance policy reserves measured in accordance with the Company's accounting policy for insurance contracts acquired. VOBA was based on an actuarial estimate of the present value of future distributable earnings for insurance in force on the acquisition date. VOBA net of accumulated amortization was $70.5 million as of December 31, 2022 and is being amortized by product based on the present value of future premiums to be received. The Company estimates that it will recognize VOBA amortization of $5.8 million in 2023, $5.4 million in 2024, $5.1 million in 2025, $4.7 million in 2026 and $4.4 million in 2027. The Company accounts for the value of distribution acquired (VODA) associated with the acquisition of NTA based on an actuarial estimate of the present value of future business to be written by the existing distribution channel. VODA net of accumulated amortization was $38.9 million as of December 31, 2022 and is being amortized on a straight-line basis. The Company estimates that it will recognize VODA amortization of $2.9 million in each of the years 2023 through 2027, respectively. The Company accounts for VODA associated with the acquisition of BCG Securities, Inc. (BCGS) based on management's estimate of the present value of future business to be written by the existing distribution channel. VODA net of accumulated amortization was $0.5 million as of December 31, 2022 and is being amortized based on the present value of future profits to be received. The cumulative amortization the Company expects to recognize for the years 2023 through 2027 is insignificant. The Company accounts for the value of agency relationships based on the present value of commission overrides retained by NTA. Agency relationships net of accumulated amortization was $8.8 million as of December 31, 2022 and is being amortized based on the present value of future premiums to be received. The Company estimates that it will recognize agency relationships amortization of $1.6 million in 2023, $1.4 million in 2024, $1.2 million in 2025, $1.0 million in 2026 and $0.9 million in 2027. The Company accounts for the value of customer relationships based on the present value of expected profits from existing Benefit Consultants Group, Inc. (BCG) and Madison National customers in force at the date of acquisition. Customer relationships net of accumulated amortization was $53.2 million as of December 31, 2022 and is being amortized based on the present value of future profits to be received for BCG and based on the present value of future premiums for Madison National. The Company estimates that it will recognize customer relationships amortization of $4.6 million in 2023, $4.9 million in 2024, $5.2 million in 2025, $5.6 million in 2026 and $6.0 million in 2027. The trade names intangible asset represents the present value of future savings accruing to NTA, BCG and BCGS by virtue of not having to pay royalties for the use of the trade names, valued using the relief from royalty method. The state licenses intangible asset represents the regulatory licenses held by NTA and Madison National that were valued using the cost approach. Both the trade names and state licenses are indefinite-lived intangible assets that are not subject to amortization. Annually, the Company performs a VOBA analysis on supplemental insurance policies to assess whether a loss recognition event has occurred. This initially involves comparing the historical and expected future experience on the block to the assumptions embedded in the original VOBA intangible asset. If both the experience to date and current expected experience are consistently better than the initial VOBA assumptions, the remaining value in the block is sufficient to support the VOBA intangible asset and no loss recognition is necessary. If the historical and current expected assumptions are not uniformly better than the initial VOBA assumptions, a GPV is performed to assess whether a loss recognition event has occurred. This involves discounting expected future benefits and expenses less expected future premiums. To the extent that this amount is greater than the liability for future benefits less the VOBA intangible asset, in aggregate for the supplemental insurance block, a loss would be recognized by first writing-off the VOBA and then increasing the liability. Currently, a GPV is not required for the acquired supplemental block. No such costs were deemed unrecoverable during the year ended December 31, 2022. Amortizing intangible assets (i.e., VODA, agency relationships and customer relationships) are tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. The carrying amount of an amortizing intangible asset is not recoverable if it exceeds the sum of undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount is not recoverable from undiscounted cash flows, the impairment is measured as the difference between the carrying amount and fair value. Intangible assets that are not subject to amortization (i.e., trade names and state licenses) are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of an intangible asset that is not subject to amortization exceeds its fair value, an impairment loss is recognized in an amount equal to the excess. As of October 1, 2022, the Company performed a qualitative assessment to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessment of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset is less than its carrying amount with the exception of lower than anticipated BCG revenues which triggered a requirement to evaluate the intangible assets associated with BCG. For the evaluation, the fair value of BCG's intangible assets were measured using discounted cash flow methods. The carrying amounts for customer relationships and trade names exceeded the fair values resulting in a $2.5 million intangible asset impairment charge for customer relationships and a $0.3 million intangible asset impairment charge for trade names. As of October 1, 2021, the Company performed both qualitative assessments and quantitative impairment tests for intangible assets and concluded that no impairments were warranted. As of October 1, 2020, the Company performed qualitative assessments to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessments of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset was less than its carrying amount with the exception of VODA and trade names intangible assets assigned to BCGS, for which quantitative intangible asset impairment tests were performed that resulted in intangible asset impairment charges of $4.4 million in aggregate. Goodwill When the Company was acquired from CIGNA Corporation by HME Holdings, Inc. in 1989, goodwill was recognized in the application of purchase accounting. In 1994, goodwill was recognized with respect to the acquisition of Horace Mann Property & Casualty Insurance Company. In 2019, goodwill was recognized with respect to the acquisitions of BCG, BCGS and NTA. In 2022, goodwill was recognized with respect to the acquisition of Madison National. Goodwill represents the excess of the amounts paid to acquire a business over the fair value of its net assets at the date of acquisition. Goodwill is not amortized, but is tested for impairment at the reporting unit level at least annually or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A reporting unit is defined as an operating segment or a business unit one level below an operating segment, if separate financial information is prepared and regularly reviewed by management at that level. The Company's reporting units, for which goodwill has been allocated, are Property & Casualty, Life, BCG, BCGS, Supplemental and Group Benefits. Refer to Note 7 for the allocation of goodwill by reporting segment as of December 31, 2022. The goodwill impairment test, as defined in GAAP, allows an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the entity performs a quantitative goodwill impairment test by comparing the fair value of a reporting unit to its carrying amount for purposes of confirming and measuring an impairment. Goodwill impairment is the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. Any amount of goodwill determined to be impaired is recognized as an expense in the period in which the impairment determination is made. As of October 1, 2022, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount with the exception of lower than anticipated BCG revenues which triggered an impairment of the goodwill associated with the BCG reporting unit within the Retirement operating segment. For the evaluation, the fair value of BCG was measured using a discounted cash flow method. The carrying amount exceeded the fair value, resulting in a $2.0 million goodwill impairment charge. As of October 1, 2021, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. As of October 1, 2020, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount with the exception of lower than anticipated BCGS wealth management sales outside of the education markets which triggered an impairment of the goodwill associated with the BCG reporting unit within the Retirement operating segment. For the evaluation, the fair value of BCGS was measured using a discounted cash flow method. The carrying amount exceeded the fair value, resulting in a $5.6 million goodwill impairment charge. During each year from 2020 through 2022, the Company completed the required annual goodwill impairment testing. With exception to the goodwill impairment charges described in Note 7, no other goodwill impairment charges were necessary as a result of such assessments. The assessment of goodwill recoverability requires significant judgment and is subject to inherent uncertainty. The use of different assumptions, within a reasonable range, could cause the fair value of a reporting unit to fall below its carrying amount. Subsequent goodwill assessments could result in impairment, particularly for any reporting unit with at-risk goodwill, due to the impact of a volatile financial market on earnings, discount rate assumptions, liquidity and market capitalization. Property and Equipment Property and equipment is carried at cost less accumulated depreciation, which is calculated using the straight-line method and based on the estimated useful lives of the assets. The estimated life for real estate is identified by specific property and range from 20 to 45 years. The estimated useful lives of leasehold improvements and other property and equipment, including capitalized software, generally range from 3 to 10 years. The following amounts are included in Other assets in the Consolidated Balance Sheets: ($ in millions) December 31, 2022 2021 Property and equipment $ 148.3 $ 136.4 Less: accumulated depreciation 79.0 70.4 Total $ 69.3 $ 66.0 Separate Account Variable Annuity Assets and Liabilities Separate Account variable annuity assets represent contractholder funds invested in various mutual funds. The Separate Account variable annuity assets comprise actively traded mutual funds that have daily quoted net asset values that are readily determinable for identical assets that the Company can access. Net asset values for the actively traded mutual funds in which the Separate Account variable annuity assets are invested are obtained daily from the fund managers. Separate Account variable annuity liabilities are equal to the estimated fair value of Separate Account variable annuity assets. The investment income, gains and losses of these accounts accrue directly to the contractholders and are not included in the results of operations of the Company. The activity of the Separate Accounts is not reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss) except for (1) contract charges earned, (2) the activity related to contract guarantees, which are benefits on existing variable annuity

Business Combination and Asset Acquisition [Abstract]
Acquisitions	AcquisitionsEffective January 1, 2022, the Company acquired all the equity interests in Madison National pursuant to a Stock Purchase Agreement (Agreement) dated as of July 14, 2021. The final adjusted purchase price of the transaction was $172.3 million. The seller of Madison National has a potential earn-out of up to $12.5 million payable in cash, if specified financial targets are achieved by the end of 2023. As a result of the acquisition, Madison National became a wholly owned subsidiary of the Company. Madison National is a leading writer of employer-sponsored benefits provided to educators by K-12 school districts. Founded in 1961 and headquartered in Madison, Wisconsin, Madison National offers short-term and long-term group disability, group term life, and worksite solutions products, including accident and critical illness. Madison National's results are being reported in the reporting segment titled "Supplemental & Group Benefits". The amount of revenues and pretax income for Madison National since the date of acquisition included in the Company's Consolidated Statement of Operations and Other Comprehensive Income (Loss) for the year ended December 31, 2022 are $140.9 million and $13.8 million (inclusive of the $4.7 million non-cash impact from amortization of intangible assets under purchase accounting), respectively. During the fourth quarter of 2022, the Company finalized its estimates of the fair value of Madison National assets acquired and liabilities assumed, including, but not limited to, intangible assets, policy reserves, certain tax-related balances and certain investments. In accordance with Accounting Standards Codification (ASC) 805, Business Combinations, there were no adjustments to the preliminary estimates of the assets acquired and liabilities assumed. The Company has allocated all of the goodwill associated with the Madison National acquisition to the Supplemental & Group Benefits reporting segment. The factors that contributed to recognition of goodwill include synergies from economies of scale within underwriting operations, acquiring a talented workforce and cost savings opportunities. Based on the Company's final allocation of the purchase price, the fair value of the assets acquired and liabilities assumed were as follows: ($ in millions) Assets: Investments $ 90.4 Cash and short-term investments 123.4 Reinsurance recoverable 356.0 Intangible assets (1) 59.4 Other assets 23.2 Liabilities: Investment contract and policy reserves 274.5 Unpaid claims and claim expenses 48.2 Unearned premiums 1.5 Other policyholder funds 152.8 Other liabilities 15.9 Total identifiable net assets acquired 159.5 Goodwill (2) 12.8 Purchase price $ 172.3 (1) Intangible assets consist of the value of business acquired, value of customer relationships and state licenses.

Generally, such sales are due to issuer specific events occurring subsequent to the reporting date that result in a change in the Company's intent or ability to hold a fixed maturity security. The types of events that may result in a sale include significant changes in economic facts and circumstances related to the fixed maturity security, significant unforeseen changes in liquidity needs, or changes in the Company's investment strategy.

The following table presents the fair value and gross unrealized losses for fixed maturity securities in an unrealized loss position as of December 31, 2022 and 2021. The Company views the decrease in fair value of all fixed maturity securities with unrealized losses as of December 31, 2022 — 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 December 31, 2022, 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 anticipated recovery in value. There has been a significant increase in interest rates since December 31, 2021, driven mostly by increases in U.S. Treasury rates, though credit spreads also widened. The 10-year U.S. Treasury yield increased 236 basis points for the year ended December 31, 2022, rising from 1.51% as of December 31, 2021 to 3.87% as of December 31, 2022. Additionally, credit spreads widened during the same time period, with investment grade and high yield wider by 40 and 171 basis points, respectively. These upward movements in rates caused market yields in the Company's portfolios to rise sharply, with downward pressure on prices. Investment grade and high yield total returns for the year ended December 31, 2022 were down 15.4% and 11.2%, respectively. The Bloomberg Barclays Index Yield-to-Worst for Investment Grade rose 3.1% for the year ended December 31, 2022, ending at 5.4%, while the High Yield Index rose 4.8% to 9.0%. The Company's 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 December 31, 2022.

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 decline include operating performance, comparable public company earnings multiples, capitalization rates and the economic environment. The Company recognizes an impairment loss for equity method 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 equity method limited partnership interests were as follows: ($ in millions) December 31, 2022 2021 Commercial mortgage loan funds $ 593.6 $ 346.8 Private equity funds 76.3 74.0 Infrastructure equity funds 72.0 58.3 Real estate equity funds 71.3 46.3 Infrastructure debt funds 60.0 62.4 Other funds (1) 110.5 125.0 Total $ 983.7 $ 712.8 (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 provide that the Company will receive or pledge financial collateral in the event minimum thresholds have been reached.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	The Company is required to disclose estimated fair values for certain financial and nonfinancial assets and liabilities. Fair values for the Company's insurance contracts other than annuity contracts (which are investment contracts) and equity method limited partnership interests are not required to be disclosed in fair value hierarchy. 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 the matching of investment maturities with amounts due under insurance contracts. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between knowledgeable, unrelated and willing market participants on the measurement date. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company categorizes the fair value of its financial and nonfinancial assets and liabilities into a three-level hierarchy based on the priority of inputs to the valuation technique. The three levels of inputs that may be used to measure fair value are: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include certain fixed maturity and equity securities that are traded in an active exchange market, as well as U.S. Treasury securities. Level 2 Unadjusted observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for the assets or liabilities. Level 2 assets and liabilities include fixed maturity securities (1) with quoted prices that are traded less frequently than exchange-traded instruments or (2) values based on discounted cash flows with observable inputs. This category generally includes certain U.S. Government and agency mortgage-backed securities, non-agency structured securities, corporate fixed maturity securities, preferred stocks, derivatives and embedded derivatives. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, certain discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation and for which the significant inputs are unobservable. This category generally includes certain private debt and equity instruments, as well as embedded derivatives. When the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. As a result, a Level 3 fair value measurement may include inputs that are observable (Level 1 or Level 2) and unobservable (Level 3). Net transfers into or out of each of the three levels are reported as having occurred at the end of the reporting period in which the transfers were determined. The following discussion describes the valuation methodologies used for financial assets and financial liabilities measured at fair value. The techniques utilized in estimating fair value are affected by the assumptions used, including discount rates and estimates of the amount and timing of expected future cash flows. The use of different methodologies, assumptions and inputs may have a material effect on the estimated fair values of the Company's financial assets and liabilities. Judgment is exercised in deriving conclusions about the Company's business, its value or financial position based on the fair value information of financial assets and liabilities presented below. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial asset or financial liability, including estimates of both the timing and amount of expected future cash flows and the credit standing of the issuer. In some cases, fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial asset or financial liability. The disclosed fair values do not reflect any premium or discount that could result from offering for sale at one time an entire holding of a particular financial asset or financial liability. In periods of market disruption, the ability to observe prices and inputs may be reduced for many financial instruments. This condition could cause a financial instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3. Potential taxes and other expenses that would be incurred in an actual sale or settlement are not reflected in the fair value amounts disclosed. Investments The fair value of a fixed maturity security is the estimated amount at which the security could be exchanged in an orderly transaction between knowledgeable, unrelated and willing parties. The Company utilizes ICE Data Pricing, its investment managers and custodian bank to obtain fair value prices from independent third-party valuation service providers, broker quotes, model prices and matrix pricing. Each month, the Company obtains fair value prices from its investment managers and custodian bank, each of which use a variety of independent, nationally recognized pricing sources to determine market valuations for fixed maturity securities. Differences in prices between the sources that the Company considers significant are researched and the Company utilizes the price that it considers most representative of an exit price. Typical inputs used by these pricing sources include, but are not limited to, reported trades, bids, offers, benchmark yield curves, benchmarking of similar securities, rating designations, sector groupings, issuer spreads and/or estimated cash flows, prepayment and default speeds, among others. The Company's fixed maturity securities portfolio is primarily publicly traded, which allows for a high percentage of the fixed maturity securities portfolio to be priced through pricing services. Approximately 88.6% and 90.2% of the fixed maturity securities portfolio, based on fair value, was priced through pricing services or index priced as of December 31, 2022 and 2021, respectively. The remainder of the fixed maturity securities portfolio was priced by broker quotes, model prices or matrix pricing. When non-binding broker quotes can be corroborated by comparison to other vendor quotes, pricing models or analyses, the fixed maturity securities are generally classified as Level 2, otherwise they are classified as Level 3. There were no significant changes to the valuation process during 2022. The valuation of hard-to-value fixed maturity securities (generally 75 -125 securities) is more subjective because the markets are less liquid and there is a lack of observable market-based inputs. This may increase the potential that the estimated fair value of an investment is not reflective of the price at which an actual transaction would occur. When the pricing sources cannot provide fair value determinations, the investment managers obtain non-binding price quotes from brokers. For those securities where the investment manager cannot obtain broker quotes, they will model the security, generally using estimated cash flows of the underlying collateral. Brokers' valuation methodologies as well as investment managers’ modeling methodologies are sometimes matrix-based, using indicative evaluation measures and adjustments for specific security characteristics and market sentiment. The selection of the market inputs and assumptions used to estimate the fair value of hard-to-value fixed maturity securities requires judgment and includes: benchmark yield, liquidity premium, estimated cash flows, prepayment speeds and default rates, spreads, weighted average life, and credit rating. The extent of the use of each market input depends on the market sector and market conditions. Depending on the security, the priority of the use of inputs may change or some market inputs may not be relevant. For some securities, additional inputs may be necessary. The Company gains assurance that its portfolio of fixed maturity securities including hard-to-value fixed maturity securities is appropriately valued through the execution of various processes and controls designed to ensure the overall reasonableness and consistent application of valuation methodologies, including inputs and assumptions, and compliance with GAAP. The Company’s processes and controls are designed to ensure (1) the valuation methodologies are appropriate and consistently applied, (2) the inputs and assumptions are reasonable and consistent with the objective of determining fair value, and (3) the fair values are accurately recorded. For example, on a continuing basis, the Company assesses the reasonableness of individual fair values that have stale security prices or that exceed certain thresholds as compared to previous fair values received from valuation service providers. The Company performs procedures to understand and assess the methodologies, processes and controls of valuation service providers. In addition, the Company may validate the reasonableness of fair values by comparing information obtained from valuation service providers or brokers to other third-party valuation sources for selected securities. To determine the fair value of equity securities, the Company utilizes its investment managers and its custodian bank to obtain fair value prices from independent third-party valuation service providers. Each month, the Company obtains fair value prices from its investment managers and custodian bank, each of which use a variety of independent, nationally recognized pricing sources to determine market valuations for equity securities. In summary, the following financial assets and financial liabilities are carried at fair value on a recurring basis: Financial assets • Fixed maturity securities, including hard-to-value fixed maturity securities, as described above. • Equity securities, as described above. • Short-term fixed maturity securities — Because of the nature of these assets, carrying amounts generally approximate fair values. • Derivatives — Fair values are based on the amount of cash expected to be received to settle each derivative on the reporting date. These amounts are obtained from each of the counterparties using industry accepted valuation models and observable inputs. Significant inputs include contractual terms, underlying index prices, market volatilities, interest rates and dividend yields. • FHLB membership and activity stocks — Fair value is based on redemption value, which is equal to par value. Financial liabilities • The fair value of derivatives embedded in IUL contracts is set equal to the fair value of the outstanding call options. • The fair value of derivatives embedded in FIA contracts is determined using the option budget method for each premium received (i.e., the option budget method is used as the future account growth rate). With this method, future excess cash flows (defined as benefits in excess of required non-forfeiture benefits) are discounted at the risk-free rate and adjusted for non-performance, to determine the fair value of the embedded derivatives. 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. As of December 31, 2022, Level 3 investments comprised approximately 7.8% of the Company's total investment portfolio at fair value.

(3) Transfers into and out of Level 3 during the years ended December 31, 2022 and 2021 were attributable to changes in the availability of observable market information for individual fixed maturity securities and short-term investments. 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. As of December 31, 2022, the Company had a $3.4 million net investment loss on Level 3 financial assets that was included in net income and was primarily attributable to credit loss impairments. As of December 31, 2021 the Company had a $8.1 million net investment loss on Level 3 financial assets that was included in net income. For the years ended December 31, 2022 and 2021, a net investment gain of $12.9 million and a net investment loss of $10.0 million, respectively, were included in net income that 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.

(4) "T spread" is a specific point on the OTR curve. (5) Mortality multiplier is applied to the Annuity 2000 table. (6) 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 previously described in this Note. 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 mainly dissimilar 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 following table presents the carrying amount and fair value of the Company’s financial assets and financial liabilities not carried at fair value and the level within the fair value hierarchy at which such financial assets and liabilities are categorized.

For policy loans, fair value is based on estimates using discounted cash flow analysis and current interest rates being offered for new loans. For mortgage loans, fair value is estimated by discounting the expected future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and similar remaining maturities. Deposit Asset on Reinsurance The fair value of the deposit asset on reinsurance is estimated by discounting the future cash flows that are expected to arise out of the annuity reinsurance transaction. The treasury yield curve, plus an assumed credit spread, is used to determine the appropriate discount rate. Investment Contract and Policy Reserves The fair values of fixed annuity contract liabilities and policyholder account balances on life contracts are equal to the discounted estimated future cash flows (using the Company's current interest rates for similar products including consideration of minimum guaranteed interest rates). The Company carries these financial liabilities at cost. Also, included in investment contract and policy reserves are embedded derivatives related to the Company's IUL products which are carried at fair value. See Note 5 for further information. Other Policyholder Funds Other policyholder funds are liabilities related to supplementary contracts without life contingencies and dividend accumulations, as well as balances outstanding under funding agreements with the FHLB and embedded derivatives related to the FIA products. Except for embedded derivatives, each of these components is carried at cost, which management believes is a reasonable estimate of fair value due to the relatively short duration of these items, based on the Company's past experience. The fair value of the embedded derivatives related to FIA products is estimated at each reporting date by (1) projecting policy contract values and minimum guaranteed contract values over the expected lives of the contracts and (2) discounting the excess of the projected contract value amounts at the applicable risk free interest rates adjusted for the Company's nonperformance risk related to those liabilities. The projections of policy contract values are based on the Company's best estimate assumptions for future contract growth and decrements. The assumptions for future contract growth include the expected index credits which are derived from the fair values of the underlying call options purchased to fund such index credits and the expected costs of annual call options that will be purchased in the future to fund index credits beyond the next contract anniversary. Projections of minimum guaranteed contract values include the same best estimate assumptions for contract decrements used to project policy contract values. Reverse Repurchase Agreements Reverse repurchase agreements are transactions in which the Company (transferor) transfers fixed maturity securities to another party (transferee) and receives cash (or securities), with a simultaneous agreement to repurchase the same securities (or substantially the same securities) at a specified price on a specified date. These transactions are generally short-term in nature, and therefore, the carrying amounts of these instruments approximate fair value. The Company accounts for reverse repurchase agreements as secured borrowings. This means that the fixed maturity 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 carrying amount of the Company's obligation under reverse repurchase agreements is equal to the amount of cash it received on the date of transfer and the fair value of the Company's obligation under reverse repurchase agreements is equal to the-then current fair value of the fixed maturity securities transferred as of the reporting date. Short-term Debt The Company carries short-term debt at amortized cost which approximates fair value. Long-term Debt The Company carries long-term debt at amortized cost. The fair value of long-term debt is estimated based on unadjusted quoted market prices of the Company's securities or unadjusted market prices based on similar publicly traded issues when trading activity for the Company's securities is not sufficient to provide a market price.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company offers FIA products, which are deferred fixed annuities that guarantee the return of principal to the contractholder and credits interest based on a percentage of the gain in a specified market index. The Company also offers IUL products which credits interest based on a percentage of the gain in a specified market index. When deposits are received for FIA and IUL contracts, a portion is used to purchase derivatives consisting of call options on the applicable market indices to fund the index credits due to FIA and IUL policyholders. For the Company, substantially all such call options are one-year options purchased to match the funding requirements of the underlying contracts. The change in fair value of derivatives includes the gains or losses recognized at the expiration of the option term or early termination and the changes in fair value for open positions. Call options are not purchased to fund the index liabilities that may arise after the next deposit anniversary date. On the respective anniversary dates of the indexed deposits, the index used to compute the annual index credit is reset and new one-year call options are purchased to fund the next annual index credit. The cost of these purchases is managed through the terms of the FIA and IUL contracts, which permit changes to index return caps, participation rates and/or asset fees, subject to guaranteed minimums on each contract's anniversary date. By adjusting the index return caps, participation rates or asset fees, crediting rates generally can be managed except in cases where the contractual features would prevent further modifications. The future annual index credits on FIA are accounted for as a "series of embedded derivatives" over the expected life of the applicable contract with a corresponding reserve recognized. For IUL, the embedded derivative represents a single-year liability for the index return. The Company carries all derivatives at fair value in the Consolidated Balance Sheets. The Company elected to not use hedge accounting for derivative transactions related to the FIA and IUL products. As a result, the Company recognizes the purchased call options and the embedded derivatives related to the provision of a contingent return at fair value, with changes in the fair value of the derivatives recognized immediately as Net investment gains (losses) in the Consolidated Statements of Operations and Comprehensive Income (Loss). The fair values of derivatives, including derivatives embedded in FIA and IUL contracts, are presented in the Consolidated Balance Sheets as follows: ($ in millions) December 31, 2022 2021 Assets Derivatives, reported in Short-term and other investments $ 6.8 $ 10.7 Liabilities FIA - embedded derivatives, reported in Other policyholder funds 91.0 106.6 IUL - embedded derivatives, reported in Investment contract and policy reserves 1.2 2.1 In general, the change in the fair value of the embedded derivatives related to FIA will not correspond to the change in fair value of the purchased call options because the purchased call options are one-year options while the fair value of the embedded derivatives represent the rights of the policyholder to receive index credits over the entire period the FIA contracts are expected to be in force, which typically exceeds 10 years. The changes in fair value of derivatives included in the Consolidated Statements of Operations and Comprehensive Income (Loss) were as follows: ($ in millions) Years Ended December 31, 2022 2021 2020 Change in fair value of derivatives: (1) Net investment gains (losses) $ (9.7) $ 8.7 $ 0.2 Change in fair value of embedded derivatives: Net investment gains (losses) 14.9 (11.3) (12.1) (1) Includes gains (losses) recognized at option expiration or early termination and changes in fair value for open positions. The Company's strategy attempts to mitigate potential risk of loss under these agreements through a regular monitoring process, which evaluates the program's effectiveness. The Company is exposed to risk of loss in the event of nonperformance by the counterparties and, accordingly, option contracts are purchased from multiple counterparties, which are evaluated for creditworthiness prior to purchase of the contracts. All of these options have been purchased from nationally recognized financial institutions with a S&P/Moody's Investors Service, Inc.

Reinsurance Disclosures [Abstract]
Deposit Asset on Reinsurance	The Company reinsures a $3.1 billion block of in force fixed and variable annuity business with a minimum crediting rate of 4.5%. The reinsured fixed business represents approximately 50% of the Company’s in force fixed annuity account balances. The arrangement contains investment guidelines and a trust to help meet the Company’s risk management objectives. Under the annuity reinsurance agreement, approximately $2.5 billion of fixed annuity reserves are reinsured on a coinsurance basis. The separate account assets and liabilities of approximately $0.6 billion are reinsured on a modified coinsurance basis and thus, remain on the Company's consolidated financial statements, but the related results of operations are fully reinsured. The annuity reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk. Therefore, the Company recognizes the annuity reinsurance agreement using the deposit method of accounting. The assets transferred to the reinsurer as consideration paid is reported as a Deposit asset on reinsurance on the Company's Consolidated Balance Sheets. As amounts are received or paid, consistent with the underlying reinsured contracts, the Deposit asset on reinsurance is adjusted. The Deposit asset on reinsurance is accreted to the estimated ultimate cash flows using the interest method and the adjustment is reported as Net investment income. Interest accreted on the Deposit asset on reinsurance was $103.5 million and $101.1 million for the years ended December 31, 2022 and 2021, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company conducts goodwill impairment testing at the reporting unit level at least annually or more frequently if events occur or circumstances change that indicate that the carrying amount may not be recoverable. See Note 1 for further description of impairment testing. At October 1, 2022, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount with the exception of lower than anticipated BCG revenues which triggered an impairment of the goodwill associated with the BCG reporting unit within the Retirement operating segment. For the evaluation, the fair value of BCG was measured using a discounted cash flow method. The carrying amount exceeded the fair value, resulting in a $2.0 million goodwill impairment charge. At October 1, 2021, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. At October 1, 2020, the Company performed a quantitative goodwill impairment test. Based on the results of the test, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount with the exception of lower than anticipated BCGS wealth management sales outside of the education markets which triggered an impairment of the goodwill associated with the BCGS reporting unit within the Retirement operating segment. For the evaluation, the fair value of BCGS was measured using a discounted cash flow method. The carrying amount exceeded the fair value, resulting in a $5.6 million goodwill impairment charge. Goodwill impairment charges are reported as Other expense - goodwill and intangible asset impairments in the Consolidated Statements of Operations and Comprehensive Income (Loss). The changes in the carrying amount of goodwill by reporting segment for the year ended December 31, 2022 were as follows: ($ in millions) Property & Casualty Life & Retirement Supplemental & Group Benefits Total Balance as of January 1, 2020 Goodwill $ 9.5 $ 48.0 $ 19.6 $ 77.1 Accumulated impairment losses — (28.0) — (28.0) Total goodwill, net 9.5 20.0 19.6 49.1 Acquisitions — — — — Impairments — (5.6) — (5.6) Balance as of December 31, 2020 Goodwill 9.5 48.0 19.6 77.1 Accumulated impairment losses — (33.6) — (33.6) Total goodwill, net 9.5 14.4 19.6 43.5 Acquisitions — — — — Impairments — — — — Balance as of December 31, 2021 Goodwill 9.5 48.0 19.6 77.1 Accumulated impairment losses — (33.6) — (33.6) Total goodwill, net 9.5 14.4 19.6 43.5 Acquisitions — — 12.8 12.8 Impairments — (2.0) — (2.0) Balance as of December 31, 2022 Goodwill 9.5 48.0 32.4 89.9 Accumulated impairment losses — (35.6) — (35.6) Total goodwill, net $ 9.5 $ 12.4 $ 32.4 $ 54.3 As of December 31, 2022, the outstanding amounts of definite-lived intangible assets subject to amortization are attributable to the acquisitions of BCG, BCGS and NTA during 2019 as well as the acquisition of Madison National during 2022. The acquisitions of BCG, BCGS, NTA and Madison National resulted in initial recognition of definite-lived intangible assets subject to amortization in the amounts of $9.1 million, $5.0 million, $160.4 million and $56.5 million, respectively. As of December 31, 2022 the outstanding amounts of definite-lived intangible assets subject to amortization were as follows: ($ in millions) Weighted Average Useful Life (in Years) At inception: Value of business acquired 28 $ 100.1 Value of distribution acquired 17 54.0 Value of agency relationships 14 17.0 Value of customer relationships 10 59.9 Total 20 231.0 Accumulated amortization and impairments: Value of business acquired (29.6) Value of distribution acquired (14.7) Value of agency relationships (8.2) Value of customer relationships (6.7) Total (59.2) Net intangible assets subject to amortization: $ 171.8 With regards to the definite-lived intangible assets in the table above, the VOBA intangible asset represents the present value of the expected underwriting profit within policies that were in force on the date of acquisition. The VODA intangible asset represents the present value of future business to be written by the existing agency force. The value of agency relationships intangible asset represents the present value of the commission overrides retained by NTA. The value of customer relationships intangible asset represents the present value of the expected profits from existing BCG and Madison National customers in force at the date of acquisition. All of the aforementioned definite-lived intangible assets were valued using the income approach. Estimated future amortization of the Company's definite-lived intangible assets were as follows: ($ in millions) Year Ending December 31, 2023 $ 14.8 2024 14.6 2025 14.4 2026 14.3 2027 14.2 Thereafter 99.5 Total $ 171.8 The VOBA intangible asset is being amortized by product based on the present value of future premiums to be received. The VODA intangible asset with respect to the acquisition of NTA is being amortized on a straight-line basis. The VODA intangible asset with respect to the acquisition of BCGS was being amortized based on the present value of future profits to be received but will be amortized on a straight-line basis subsequent to the reporting date. The value of agency relationships intangible asset is being amortized based on the present value of future premiums to be received. The value of customer relationships intangible assets are being amortized based on the present value of future profits to be received for BCG and based on the present value of future premiums for Madison National. Indefinite-lived intangible assets (not subject to amortization) as of December 31, 2022 were as follows: ($ in millions) December 31, Impairments Acquisitions December 31, Trade names $ 7.9 $ (0.3) $ — $ 7.6 State licenses 2.9 — 2.9 5.8 Total $ 10.8 $ (0.3) $ 2.9 $ 13.4 The trade names intangible asset represents the present value of future savings accruing to NTA, BCG and BCGS by virtue of not having to pay royalties for the use of the trade names, valued using the relief from royalty method. The state licenses intangible asset represents the regulatory licenses held by NTA and Madison National that were valued using the cost approach. The Company conducts intangible asset impairment testing at least annually, or more often if events, changes or circumstances indicate that the carrying amounts may not be recoverable. See Note 1 for further description of impairment testing. At October 1, 2022, the Company performed a qualitative assessment to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessment of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset is less than its carrying amount with the exception of lower than anticipated BCG revenues which triggered a requirement to evaluate the intangible assets associated with BCG. For the evaluation, the fair value of BCG's intangible assets were measured using discounted cash flow methods. The carrying amounts for customer relationships and trade names exceeded their fair values resulting in a $2.5 million intangible asset impairment charge for customer relationships and a $0.3 million intangible asset impairment charge for trade names. At October 1, 2021, the Company performed a qualitative assessment to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessment of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset is less than its carrying amount. At October 1, 2020, the Company performed a qualitative assessment to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessment of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset is less than its carrying amount with the exception of lower than anticipated BCGS wealth management sales outside of the education markets which triggered a requirement to evaluate the intangible assets associated with BCGS. For the evaluation, the fair value of BCGS' intangible assets were measured using discounted cash flow methods. The carrying amounts for VODA and trade names exceeded their fair values resulting in a $3.6 million intangible asset impairment charge for VODA and a $0.8 million intangible asset impairment charge for trade names. Intangible asset impairment charges are reported as Other expense - goodwill and intangible asset impairments

Insurance Loss Reserves [Abstract]
Unpaid Claims and Claim Expense Reserves	Unpaid Claims and Claim Expense Reserves Property & Casualty Unpaid Claims and Claim Expense Reserves The following table is a summary reconciliation of the beginning and ending Property & Casualty unpaid claims and claim expense reserves for the periods indicated. The table presents reserves on both a gross and net (after reinsurance) basis. The total net Property & Casualty insurance claims and claim expense incurred amounts are reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss). The end of the year gross reserve (before reinsurance balances and reinsurance recoverable balances) are reflected on a gross basis in the Consolidated Balance Sheets. ($ in millions) Years Ended December 31, 2022 2021 2020 Property & Casualty Gross reserves, beginning of year $ 362.4 $ 372.2 $ 387.0 Less: reinsurance recoverables 110.3 112.9 120.5 Net reserves, beginning of year (1) 252.1 259.3 266.5 Incurred claims and claim expenses: Claims occurring in the current year 512.3 455.1 441.2 Increase (decrease) in estimated reserves for claims occurring in prior years (2) 22.0 (7.2) (10.2) Total claims and claim expenses incurred 534.3 447.9 431.0 Claims and claim expense payments for claims occurring during: Current year 320.0 307.1 291.4 Prior years 178.5 148.0 146.8 Total claims and claim expense payments 498.5 455.1 438.2 Net reserves, end of year 287.9 252.1 259.3 Plus: reinsurance recoverables 100.8 110.3 112.9 Gross reserves, end of year $ 388.7 $ 362.4 $ 372.2 (1) Reserves are net of anticipated reinsurance recoverables. (2) Shows the amounts by which the Company increased (decreased) its reserves in each of the periods indicated for claims occurring in previous periods to reflect subsequent information on such claims and changes in their projected final settlement costs. Also, refer to the paragraphs below for additional information regarding prior years' reserve development recognized in 2022, 2021 and 2020. Underwriting results for Property & Casualty are significantly influenced by estimates of the Company's ultimate liability for insured events. There is a high degree of uncertainty inherent in the estimates of ultimate losses underlying the liability for unpaid claims and claim settlement expenses. This inherent uncertainty is particularly significant for liability-related exposures due to the extended period, often many years, which transpires between a loss event, receipt of related claims data from policyholders and ultimate settlement of the claim. Reserves for Property & Casualty claims include provisions for payments to be made on reported claims (case reserves), IBNR claims and associated settlement expenses (together, loss reserves). The process by which these loss reserves are established requires reliance upon estimates based on known facts and on interpretations of circumstances, including the Company's experience with similar cases and historical trends involving claim payments and related patterns, pending levels of unpaid claims and product mix, as well as other factors including court decisions, economic conditions, public attitudes and medical costs. The Company believes the Property & Casualty loss reserves are appropriately established based on available facts, laws, and regulations. The Company calculates and recognizes a single best estimate of the reserve as of each reporting date, for each line of business and its coverages for reported losses and for IBNR losses and as a result, the Company believes no other estimate is better than the recognized amount. Due to uncertainties involved, the ultimate cost of losses may vary materially from recognized amounts. The Company continually updates loss estimates using both quantitative and qualitative information from its reserving actuaries and information derived from other sources. Adjustments may be required as information develops which varies from experience, or, in some cases, augments data which previously was not considered sufficient for use in determining liabilities. The effects of these adjustments may be significant and are charged or credited to income in the period in which the adjustments are made. Numerous risk factors will affect more than one product line. One of these factors is changes in claim department practices, including claim closure rates, number of claims closed without payment, the use of third-party claim adjusters and the level of needed case reserve estimated by the adjuster. Other risk factors include changes in claim frequency, changes in claim severity, regulatory and legislative actions, court actions, changes in economic conditions and trends (e.g., medical costs, labor rates and the cost of materials), the occurrence of unusually large or frequent catastrophic loss events, timeliness of claim reporting, the state in which the claim occurred and degree of claimant fraud. The extent of the impact of a risk factor will also vary by coverages within a product line. Individual risk factors are also subject to interactions with other risk factors within product line coverages. While all product lines are exposed to these risks, there are some loss types or product lines for which the financial effect will be more significant. For instance, given the relatively large proportion (approximately 71.4% as of December 31, 2022) of the Company's reserves that are in the longer-tail auto liability coverages, regulatory and court actions, changes in economic conditions and trends, and medical costs could be expected to impact this product line more extensively than others. Reserves are established for claims as they occur for each line of business based on estimates of the ultimate cost to settle the claims. The actual loss results are compared to prior estimates and differences are recorded as re-estimates. The primary actuarial techniques (development of paid loss dollars, development of reported loss dollars, methods based on expected loss ratios and methods utilizing frequency and severity of claims) used to estimate reserves and provide for losses are applied to actual paid losses and reported losses (paid losses plus individual case reserves set by claim adjusters) for an accident year to create an estimate of how losses are likely to develop over time. An accident year refers to classifying claims based on the year in which the claims occurred. For estimating short-tail coverage reserves (e.g., homeowners and auto physical damage), which comprise approximately 28.3% of the Company's total loss reserves as of December 31, 2022, the primary actuarial technique utilized is the development of paid loss dollars due to the relatively quick claim settlement period. As it relates to estimating long-tail coverage reserves (primarily related to auto liability), which comprise approximately 71.4% of the Company's total loss reserves as of December 31, 2022, the primary actuarial technique utilized is the development of reported loss dollars due to the relatively long claim settlement period. In all of the loss estimation techniques referred to above, a ratio (development factor) is calculated which compares current results to results in the prior period for each accident year. Various development factors, based on historical results, are multiplied by the current experience to estimate the development of losses of each accident year from the current time period into the next time period. The development factors for the next time period for each accident year are compounded over the remaining calendar years to calculate an estimate of ultimate losses for each accident year. Occasionally, unusual aberrations in loss patterns are caused by factors such as changes in claim reporting, settlement patterns, unusually large losses, process changes, legal or regulatory environment changes, and other influences. In these instances, analyses of alternate development factor selections are performed to evaluate the effect of these factors and judgment is applied to make appropriate development factor assumptions needed to develop a best estimate of ultimate losses. Paid losses are then subtracted from estimated ultimate losses to determine the indicated loss reserves. The difference between indicated reserves and recorded reserves is the amount of reserve re-estimate. Reserves are re-estimated quarterly. When new development factors are calculated from actual losses that differ from estimated development factors used in previous reserve estimates, assumptions about losses and required reserves are revised based on the new development factors. Changes to reserves are recognized in the period in which development factor changes result in reserve re-estimates. Claim count estimates are also established for claims as they occur for each line of business based on estimates of the ultimate claim counts. These counts are derived by counting the number of claimants by insurance coverage. The primary actuarial techniques (development of paid claim counts and development of reported claim counts) used to estimate ultimate claim counts are applied to actual paid claim counts and reported claim counts (paid claims plus individual unpaid claims set by claim adjusters) for an accident year to create an estimate of how claims are likely to develop over time. An accident year refers to classifying claims based on the year in which the claim occurred. The ultimate claim count generally gives equal consideration to the results of the two actuarial techniques described. Occasionally, unusual aberrations in claim reporting patterns or claim payment patterns may occur. In these instances, analyses of alternate development factor selections are performed to evaluate the effect of these factors and judgment is applied to make appropriate development factor assumptions needed to develop a best estimate of ultimate claims. See tables on the following pages of Note 8 for details of the average annual percentage payout of incurred claims by age, also referred to as a history of claims duration and tables illustrating the incurred and paid claims development information by accident year on a net basis for the lines of homeowners, auto liability, and auto physical damage, which represents 99.7% of the Company's Property & Casualty incurred losses for 2022. Numerous actuarial estimates of the types described above are prepared each quarter to monitor losses for each line of business, including the line's individual coverages, for reported losses and IBNR. Often, several different estimates are prepared for each detailed component, incorporating alternative analyses of changing claim settlement patterns and other influences on losses, from which the Company selects the best estimate for each component, occasionally incorporating additional analyses and judgment, as described above. These estimates also incorporate the historical impact of inflation into reserve estimates, the implicit assumption being that a multi-year average development factor represents an adequate provision. Based on the Company's review of these estimates, as well as the review of independent reserve studies, the best estimate of required reserves for each line of business, including the line's individual coverages, is determined by management and is recognized for each accident year, then the required reserves for each component are summed to create the reserve balances carried on the Company's Consolidated Balance Sheets. Based on the Company's products and coverages, historical experience, and various actuarial methodologies used to develop reserve estimates, the Company estimates that the potential variability of the Property & Casualty loss reserves within a reasonable probability of other possible outcomes may be different than expected. A change in claim severity or claim frequency of approximately plus or minus 2.0% of reserves equates to plus or minus approximately $2.0 million of net income as of December 31, 2022. Although this evaluation reflects the most likely outcomes, it is possible the final outcome may fall below or above these estimates. Net favorable (unfavorable) development of total reserves for Property & Casualty claims occurring in prior years was $(22.0) million in 2022, $7.2 million in 2021 and $10.2 million in 2020. In 2022, Property & Casualty had unfavorable prior years' auto reserve development of $28.0 million, reflecting the impact on severity of overall inflation, higher medical costs, increased usage of medical services and the current judicial environment, as well as favorable prior years' property reserve development of $6.0 million as a result of favorable loss trends for accident years 2021 and prior. In 2021, the favorable development was the result of favorable loss trends in auto and homeowners loss emergence for accident years 2020 and prior. In 2020, the favorable development was predominantly the result of favorable loss trends in property for accident years 2019 and prior including the recognition of $4.8 million of subrogation received on the 2018 Camp Fire event. The Company completes a detailed study of Property & Casualty reserves based on information available at the end of each quarter and year. Trends of reported losses (paid amounts and case reserves on claims reported to the Company) for each accident year are reviewed and ultimate loss costs for those accident years are estimated. The Company engages an independent property and casualty actuarial consulting firm to prepare an independent study of the Company's Property & Casualty reserves as of December 31 st of each year. The result of the independent actuarial study as of December 31, 2022 was consistent with management's analysis and selected estimates and did not result in any adjustments to the Company's Property & Casualty reserves recognized. At the time each of the reserve analyses was performed, the Company believed that each estimate was based upon sound methodology and such methodologies were appropriately applied and that there were no trends which indicated the likelihood of future loss reserve development. The financial impact of net reserve development was therefore accounted for in the period that the development was determined. No other adjustments were made in the determination of the liabilities during the periods covered by these consolidated financial statements. Management believes that, based on data currently available, it has reasonably estimated the Company's ultimate losses. Below is the average annual percentage payout of incurred claims by age, also referred to as a history of claims duration: Average Annual Percentage Payout of Incurred Claims by Age, Net of Reinsurance Years 1 2 3 4 5 6 7 8 9 10 Homeowners 78.9 % 17.7 % 2.2 % 0.6 % 0.5 % 0.1 % — — — — Auto liability 37.9 % 34.5 % 14.7 % 6.6 % 3.4 % 1.6 % 0.6 % 0.2 % 0.4 % 0.1 % Auto physical damage 95.0 % 5.0 % — — — — — — — — The following tables illustrate the incurred and paid claims development by accident year on a net basis for the lines of homeowners, auto liability and auto physical damage.

The table presents reserves on both a gross and net (after reinsurance). The total net Group Benefits insurance claims and claim expense incurred amounts are reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss). The end of the year gross reserve (before reinsurance balances and reinsurance recoverable balances) are reflected on a gross basis in the Consolidated Balance Sheets.

(2) Shows the amounts by which the Company increased (decreased) its reserves for claims occurring in previous periods to reflect subsequent information on such claims and changes in their projected final settlement costs. Also, refer to the paragraphs below for additional information regarding prior years' reserve development recognized in 2022. The Company's Group Benefits has short-duration contracts that are generated from specialty health and group disability lines of business, and are accounted for based on actuarial estimates of the amount of loss inherent in that period’s claims, including losses incurred for which claims have not been reported. Short-duration contract loss estimates rely on actuarial observations of ultimate loss experience for similar historical events. The Company maintains loss reserves for these lines of business to cover its estimated liability for unpaid losses and loss adjustment expenses, where material, (including legal, other fees, and costs not associated with specific claims but related to the claims payment function) for reported and unreported claims incurred as of the end of each accounting period. These loss reserves are based on actuarial assumptions. Many factors could affect these reserves, including economic and social conditions, frequency and severity of claims, medical trends resulting from the influences of underlying cost inflation, changes in utilization and demand for medical services, and changes in doctrines of legal liability and damage awards in litigation. Therefore, the Company’s reserves are necessarily based on estimates, assumptions and analysis of historical experience. The Company’s results depend upon the variation between actual claims experience and the assumptions used in determining reserves and pricing products. Reserve assumptions and estimates require significant judgment and, therefore, are inherently uncertain. The Company cannot determine with precision the ultimate amounts that will be paid for actual claims or the timing of those payments. The Company's estimate of loss represents management's best estimate of the Company's liability at the reporting date. The Company believes that its liability for policy benefits and claims is reasonable and adequate to satisfy its ultimate liability. The Company primarily uses its own loss development experience, but will also supplement that with data from its outside actuaries, reinsurers and industry loss experience as warranted. To illustrate the impact that loss ratios have on the Company’s loss reserves and related expenses, each hypothetical 1% change in the loss ratio for the health business (i.e., the ratio of insurance benefits, claims and settlement expenses to earned health premiums) for the year ended December 31, 2022, would increase reserves (in the case of a higher ratio) or decrease reserves (in the case of a lower ratio) by approximately $0.8 million pretax with a corresponding increase or decrease to Benefits, claims and settlement expenses in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss). For the specialty health line of business, IBNR claims liabilities plus expected development on reported claims are calculated using standard actuarial methods and practices. The “primary” assumption in the determination of specialty health reserves is that historical claim development patterns are representative of future claim development patterns. Factors that may affect this assumption include changes in claim payment processing times and procedures, changes in time delay in submission of claims, and the incidence of unusually large claims. Liabilities for claims for specialty health coverages are computed using completion factors and expected net loss ratios derived from actual historical premium and claim data. The reserving analysis includes a review of claim processing statistical measures and large claim early notifications; the potential impacts of any changes in these factors are not material. The Company has business that is serviced by third-party administrators. From time to time, there are changes in the timing of claims processing due to any number of factors including, but not limited to, system conversions and staffing changes during the year. These changes are monitored by the Company and the effects of these changes are taken into consideration during the claim reserving process. While these calculations are based on standard methodologies, they are estimates based on historical patterns. To the extent that actual claim payment patterns differ from historical patterns, such estimated reserves may be redundant or inadequate. The effects of such deviations are evaluated by considering claim backlog statistics and reviewing the reasonableness of projected claim ratios. Other factors which may affect the accuracy of policy benefits and claim estimates include the proportion of large claims which may take longer to adjudicate, changes in billing patterns by providers and changes in claim management practices such as hospital bill audits. Since the Company's analysis considers a variety of outcomes related to these factors, the Company does not believe that any reasonably likely change in these factors will have a material effect. With regards to the Company’s group disability line of business, the two “primary” assumptions on which disability policy benefits and claims are based are: (i) morbidity levels; and (ii) recovery rates. If morbidity levels increase, for example due to an epidemic or a recessionary environment, the Company would increase reserves because there would be more new claims than expected. With regards to the assumed recovery rate, if disabled lives recover more quickly than anticipated then the existing claims reserves would be reduced; if less quickly, the existing claims reserves would be increased. Advancements in medical treatments could affect future recovery, termination, and mortality rates. In 2022, Group Benefits had net favorable prior years' reserve development of $11.1 million which was primarily the result of favorable loss trends in specialty health and group disability for loss years 2021 and prior. Below is the average annual percentage payout of incurred claims by age for Group Benefits, also referred to as a history of claims duration: Average Annual Percentage Payout of Incurred Claims by Age, Net of Reinsurance Years 1 2 3 4 5 6 7 8 9 10 Specialty health 74.9 % 24.1 % 0.5 % 0.2 % 0.1 % 0.2 % — % — % — % — % Group disability 18.0 % 17.9 % 5.6 % 2.5 % 1.8 % 1.5 % 1.2 % 0.8 % 0.5 % 0.3 % The following tables illustrate the incurred and paid claims development by accident year on a net basis for the lines of specialty health and group disability. Conditions and trends that have affected the development of these reserves in the past will not necessarily reoccur in the future. It may not be appropriate to use this cumulative history in the projection of future performance.

Insurance [Abstract]
Reinsurance and Catastrophes	Reinsurance and Catastrophes In the normal course of business, the Company's insurance subsidiaries assume and cede reinsurance with other insurers. Reinsurance is ceded primarily to limit losses from large events and to permit recovery of a portion of direct losses; however, such a transfer does not relieve the originating insurance company of primary liability. The Company is a national underwriter and therefore has exposure to catastrophic losses in certain coastal states and other regions throughout the U.S. Catastrophes can be caused by various events including hurricanes, windstorms, hail, severe winter weather, wildfires and earthquakes, and the frequency and severity of catastrophes are inherently unpredictable. The financial impact from catastrophic losses results from both the total amount of insured exposure in the area affected by the catastrophe as well as the severity of the event. The Company seeks to reduce its exposure to catastrophe losses through the geographic diversification of its insurance coverage, deductibles, maximum coverage limits and the purchase of catastrophe reinsurance. The Company's catastrophe losses incurred were approximately $80.0 million, $78.2 million and $84.4 million for the years ended December 31, 2022, 2021 and 2020, respectively. For 2022, catastrophe losses were impacted by winter storm events, wind/hail/tornado and hurricane events. The total amounts of reinsurance recoverable on unpaid insurance reserves classified as assets and included in the amounts being reported as Reinsurance balances receivable in the Consolidated Balance Sheets were as follows: ($ in millions) December 31, 2022 2021 Reinsurance recoverables on reserves and unpaid claims Property & Casualty Reinsurance companies $ 3.1 $ 10.4 State insurance facilities 97.7 99.9 Group benefits 352.4 — Life and health 9.3 9.3 Total $ 462.5 $ 119.6 As of December 31, 2022, the Company had a reinsurance recoverable in the amount of $214.1 million from National Guardian Life Insurance Company (NGL) that exceeded 10.0% of consolidated shareholders' equity as of the reporting date. NGL currently has an assigned credit rating of A by A.M. Best. The Company recognizes the cost of reinsurance premiums over the contract periods for such premiums in proportion to the insurance protection provided. Amounts recoverable from reinsurers for unpaid claims and claim settlement expenses, including estimated amounts for unsettled claims, IBNR claims and policy benefits, are estimated in a manner consistent with the insurance liability associated with the policy. The effects of reinsurance on premiums written and contract deposits; premiums and contract charges earned; and benefits, claims and settlement expenses were as follows: ($ in millions) Gross Ceded to Other Companies (1) Assumed Net Year Ended December 31, 2022 Net premiums written and contract deposits (2) $ 1,495.2 $ 62.9 $ 53.0 $ 1,485.3 Net premiums and contract charges earned 1,048.0 72.0 53.0 1,029.0 Benefits, claims and settlement expenses 787.2 43.6 18.0 761.6 Year Ended December 31, 2021 Net premiums written and contract deposits (2) 1,370.1 23.1 9.4 1,356.4 Net premiums and contract charges earned 913.2 33.3 9.7 889.6 Benefits, claims and settlement expenses 619.3 7.8 6.2 617.7 Year Ended December 31, 2020 Net premiums written and contract deposits (2) 1,369.9 20.4 9.8 1,359.3 Net premiums and contract charges earned 949.6 28.8 9.9 930.7 Benefits, claims and settlement expenses 475.7 (86.2) 7.0 568.9 (1) Excludes the annuity reinsurance agreement accounted for using the deposit method that is discussed in Note 6. (2) This measure is not based on accounting principles generally accepted in the United States of America (non-GAAP). An explanation of this non-GAAP measure is contained in the Glossary of Selected Terms included as an exhibit in the Company's reports filed with the SEC. There were no losses from uncollectible reinsurance recoverables in the three years ended December 31, 2022. Past due reinsurance recoverables as of December 31, 2022 were not material. The Company maintains property and casualty catastrophe excess of loss reinsurance coverage. For 2022, the Company's catastrophe excess of loss coverage consisted of one contract in addition to a minimal amount of coverage by the Florida Hurricane Catastrophe Fund (FHCF). The catastrophe excess of loss contract provided 95% coverage for catastrophe losses above a retention of $25.0 million per occurrence up to $175.0 million per occurrence. This contract consisted of three layers, each of which provided for one mandatory reinstatement. The layers were $25.0 million excess of $25.0 million, $40.0 million excess of $50.0 million and $85.0 million excess of $90.0 million. For liability coverages, in 2022, the Company reinsured each loss above a retention of $5.0 million per occurrence up to $20.0 million in a clash event. A clash cover is a reinsurance casualty excess contract requiring two or more casualty coverages or policies issued by the Company to be involved in the same loss occurrence for coverage to apply. The maximum individual life insurance risk retained by the Company is $0.5 million on any individual life, while either $0.1 million or $0.125 million is retained on each group life policy depending on the type of coverage. Excess amounts are reinsured. The Company also maintains a life catastrophe reinsurance program. For 2022, the Company reinsured 100% of the catastrophe risk in excess of $1.0 million up to $35.0 million per occurrence, with one reinstatement. The Company's life catastrophe risk reinsurance program covers acts of terrorism and includes nuclear, biological and chemical explosions but excludes other acts of war. With regards to worksite direct insurance products, the Company retains all of the risk on its supplemental health product lines, including accidental death risk embedded within certain products. However, the Company’s other accidental death and dismemberment risk issued through all other policies and riders are ceded 100%. With regards to employer-sponsored products, the Company has retained approximately 72.6% of gross and assumed group disability and specialty health benefits in 2022. The Company has a block of individual life and annuity benefits that is effectively 100% ceded. The Company purchases quota share reinsurance and excess reinsurance in amounts deemed appropriate by its risk committee. The Company monitors its retention amounts by product line and has the ability to adjust retention as appropriate.

Credit Agreement with Financial Institutions (Revolving Credit Facility) Effective July 12, 2021, the Company, as borrower, amended its Credit Agreement (Revolving Credit Facility). The amended Revolving Credit Facility increased the amount available from $225.0 million to $325.0 million. PNC Bank, National Association and JPMorgan Chase Bank, N.A. serve as joint lead arrangers under the amended Revolving Credit Facility, with The Northern Trust Company, KeyBank National Association, U.S. Bank National Association, Illinois National Bank and Comerica Bank as lenders participating in the syndicate. Terms and conditions of the Revolving Credit Facility are substantially consistent with the prior agreement, with an interest rate based on LIBOR plus 115 basis points. The amended Revolving Credit Facility expires on July 12, 2026. As of December 31, 2022, the amount outstanding on the Revolving Credit Facility was $249.0 million. The $76.0 million unused portion of the Revolving Credit Facility is available for use and subject to a variable commitment fee, which was 0.15% on an annual basis as of December 31, 2022. Senior Notes As of December 31, 2022, the Company had outstanding $250.0 million aggregate principal amount of 4.50% Senior Notes (Senior Notes), which will mature on December 1, 2025, issued at a discount of 0.265% resulting in an effective yield of 4.53%. Interest on the Senior Notes is payable semi-annually at a rate of 4.50%. The Senior Notes are redeemable in whole or in part, at any time, at the Company's option, at a redemption price equal to the greater of (1) 100% of the principal amount of the notes being redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted, on a semi-annual basis, at the Treasury yield (as defined in the indenture) plus 35 basis points, plus, in either of the above cases, accrued interest to the date of redemption. Federal Home Loan Bank Borrowings In 2017, Horace Mann Insurance Company (HMIC) became a member of FHLB, which provides HMIC with access to collateralized borrowings and other FHLB products. As membership requires the ownership of membership stock, in June 2017, HMIC purchased common stock to meet the membership requirement. Any borrowing from FHLB requires the purchase of FHLB activity-based common stock in an amount equal to 4.5% of the borrowing, or a lower percentage - such as 2.0% based on the Reduced Capitalization Advance Program. In the fourth quarter of 2017, HMIC purchased common stock to meet the activity-based requirement. In 2021, the Board authorized a maximum amount equal to 25% of net aggregate admitted assets less separate account assets of the insurance subsidiaries for FHLB borrowings. As of December 31, 2022, the Company had no borrowings outstanding with FHLB. Covenants The Company is in compliance with all of the financial covenants contained in the Senior Notes indenture and the Revolving Credit Facility agreement, consisting primarily of relationships of (1) debt to capital, (2) net worth, as defined in the financial covenants, (3) insurance subsidiaries' risk-based capital and (4) securities subject to funding agreements and securities lending transactions (including repurchase transactions, reverse repurchase transactions, fee-based transactions and other similar securities lending agreements).

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax assets and liabilities included in Other assets and Other liabilities, respectively, in the Consolidated Balance Sheets were as follows: ($ in millions) December 31, 2022 2021 Income tax (asset) liability Current $ (18.8) $ (9.5) Deferred 6.2 190.5 Deferred tax assets and liabilities are recognized for all future tax consequences attributable to "temporary differences" between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. There are no deferred tax liabilities that have not been recognized. The "temporary differences" that gave rise to the deferred tax balances were as follows: ($ in millions) December 31, 2022 2021 Deferred tax assets Other comprehensive income - net unrealized losses on securities $ 105.8 $ — Unearned premium reserve reduction 10.1 11.7 Compensation accruals 8.4 9.6 Impaired securities 2.0 2.3 Other comprehensive income - net funded status of benefit plans 2.3 2.7 Discounting of unpaid claims and claim expense tax reserves 2.8 2.5 Net operating loss carryforward 3.6 — Intangibles 0.1 0.1 Postretirement benefits other than pensions 0.2 0.3 Total gross deferred tax assets 135.3 29.2 Deferred tax liabilities Other comprehensive income - net unrealized gains on securities — 101.1 Deferred policy acquisition costs 73.0 37.3 Life insurance future policy benefit reserve 30.9 30.7 Life insurance future policy benefit reserve (transitional rule) 6.4 8.5 Discounting of unpaid claims and claim expense tax reserves (transitional rule) 0.5 0.6 Investment related adjustments 29.9 37.3 Other, net 0.8 4.2 Total gross deferred tax liabilities 141.5 219.7 Net deferred tax liability $ 6.2 $ 190.5 The Company evaluated sources and character of income, including historical earnings, loss carryback potential, taxable income from future reversals of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences, and taxable income from prudent and feasible tax planning strategies. Although realization of deferred tax assets is not assured, the Company believes it is more likely than not that gross deferred tax assets will be fully realized and that a valuation allowance with respect to the realization of the total gross deferred tax assets was not necessary as of December 31, 2022 and 2021. The components of the provision for income tax expense (benefit) were as follows: ($ in millions) Years Ended December 31, 2022 2021 2020 Current $ (0.7) $ 27.7 $ 16.9 Deferred (8.6) 4.4 9.4 Total income tax expense (benefit) $ (9.3) $ 32.1 $ 26.3 Income tax expense for the following periods differed from the expected tax computed by applying the federal corporate tax rate of 21% for 2022, 2021 and 2020 to income before income taxes as follows: ($ in millions) Years Ended December 31, 2022 2021 2020 Expected federal tax on income $ (2.5) $ 36.7 $ 33.5 Add (deduct) tax effects of: Tax-exempt interest (3.3) (3.9) (4.2) Dividend received deduction (3.2) (2.2) (1.5) Goodwill impairment — — 0.2 CARES Act net operating loss carryback — — (2.8) Employee share-based compensation (0.5) (1.3) (0.5) Contingent consideration (0.3) — — Compensation deduction limitation 0.7 1.5 0.7 Research and development reserve (0.4) — 0.2 Prior year adjustments 0.1 0.1 (0.2) Other, net 0.1 1.2 0.9 Income tax expense (benefit) provided on income $ (9.3) $ 32.1 $ 26.3 The Company's federal income tax returns for years prior to 2019 are no longer subject to examination by the Internal Revenue Service (IRS). The Company recognizes tax benefits from tax return positions only if it is more likely than not the position will be sustainable, upon examination, on its technical merits and any relevant administrative practices or precedents. As a result, the Company applies a more likely than not recognition threshold for all tax uncertainties. The Company records liabilities for uncertain tax filing positions where it is more likely than not that the position will not be sustainable upon audit by taxing authorities. These liabilities are reevaluated routinely and are adjusted appropriately based upon changes in facts or law. The Company has no unrecorded liabilities from uncertain tax filing positions. HMEC and its subsidiaries file a consolidated federal income tax return. The federal income tax sharing agreements between HMEC and its subsidiaries, as approved by the Board, provide that tax on income is charged to each subsidiary as if it were filing a separate tax return with the limitation that each subsidiary will receive the benefit of any losses or tax credits to the extent utilized in the consolidated tax return. Intercompany balances are settled quarterly with a final settlement after filing the consolidated federal income tax return with the IRS. National Teachers Associates Life Insurance Company and NTA Life Insurance Company of New York are not included in HMEC's consolidated federal income tax return and will file separate federal income tax returns until they are eligible to participate in HMEC's consolidated federal income tax return. This is expected to occur in 2025. Madison National Life Insurance Company is included in the consolidated federal income tax return and tax sharing agreement as of its acquisition by HMEC. A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding interest and penalties, is as follows: ($ in millions) Years Ended December 31, 2022 2021 2020 Balance as of the beginning of the year $ 1.7 $ 2.3 $ 2.0 Increases related to prior year tax positions — — 0.2 Decreases related to prior year tax positions — (0.1) — Increases related to current year tax positions — — 0.1 Settlements — — — Lapse of statute (1.3) (0.5) — Balance as of the end of the year $ 0.4 $ 1.7 $ 2.3 The Company's effective tax rate would be affected to the extent there were unrecognized tax benefits that could be recognized. There are no positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly change within the next 12 months. The Company decreased liabilities for unrecognized tax benefits in the amount of $1.3 million, $0.5 million, and $0 related to the lapse of statues for the years ended December 31, 2022, 2021, and 2020 respectively. The Company classifies all tax related interest and penalties as income tax expense. Interest and penalties were both immaterial in each of the years ended December 31, 2022, 2021 and 2020.

Equity [Abstract]
Shareholders' Equity and Share-Based Compensation	Shareholders' Equity and Share-Based Compensation Share Repurchase Program and Treasury Shares On May 25, 2022, the Board of Directors authorized a share repurchase program allowing repurchases of up to $50 million (i.e., the 2022 Program) to begin following the completion of the $50 million repurchase plan which was authorized on September 30, 2015 (i.e., the 2015 Program). Both Programs authorize the repurchase of the Company's common shares in open market or privately negotiated transactions, from time to time, depending on market conditions. The Programs do not have expiration dates and may be limited or terminated at any time without notice. The 2015 Program was completed in July 2022 and the Company began repurchasing shares under the 2022 Program. During 2022, the Company repurchased 670,816 shares of its common stock, or 1.6% of the shares outstanding as of December 31, 2021, at an aggregate cost of $24.0 million, or an average price of $35.82 per share. During 2021, the Company repurchased 140,758 shares of its common stock, or 0.2% of the shares outstanding as of December 31, 2020, at an aggregate cost of $5.3 million, or an average price of $37.49 per share. During 2020, the Company repurchased 52,095 shares of its common stock, or 0.1% of the shares outstanding as of December 31, 2019, at an aggregate cost of $2.2 million, or an average price of $41.17 per share. In total and through December 31, 2022, 1,696,221 shares were repurchased under the Programs at an average price of $34.31 per share. The repurchase of shares was funded through use of cash. As of December 31, 2022, $41.3 million remained authorized for future share repurchases under the 2022 Program. As of December 31, 2022, the Company held 25,714,153 shares in treasury. Authorization of Preferred Stock In 1996, the shareholders of HMEC approved authorization of 1,000,000 shares of 0.001 par value preferred stock. The Board is authorized to (1) direct the issuance of the preferred stock in one or more series, (2) fix the dividend rate, conversion or exchange rights, redemption price and liquidation preference, of any series of the preferred stock, (3) fix the number of shares for any series and (4) increase or decrease the number of shares of any series. No shares of preferred stock were issued or outstanding as of December 31, 2022 and 2021. 2010 Comprehensive Executive Compensation Plan In 2010, the shareholders of HMEC approved the 2010 Comprehensive Executive Compensation Plan (the Comprehensive Plan). The purpose of the Comprehensive Plan is to aid the Company in attracting, retaining, motivating and rewarding employees and non-employee Directors; to provide for equitable and competitive compensation opportunities, including deferral opportunities; to encourage long-term service; to recognize individual contributions and reward achievement of Company goals; and to promote the creation of long-term value for the Company's shareholders by closely aligning the interests of plan participants with those of shareholders. The Comprehensive Plan authorizes share-based and cash-based incentives for plan participants. In 2012, the shareholders of HMEC approved the implementation of a fungible share pool under which grants of full value shares will count against the share limit as two and one half shares for every share subject to a full value award. In May 2021, the shareholders of HMEC approved an amendment and restatement of the Comprehensive Plan which included an increase of 2,500,000 in the number of shares of common stock reserved for issuance under the Comprehensive Plan. As of December 31, 2022, approximately 1,998,249 shares were available for grant under the Comprehensive Plan. Shares of common stock issued under the Comprehensive Plan may be either authorized and unissued shares of HMEC or shares that have been reacquired by HMEC; however, new shares have been issued historically. As further described in the paragraphs below, CSUs, stock options and RSUs under the Comprehensive Plan were as follows: December 31, 2022 2021 2020 CSUs related to deferred compensation for Directors 15,372 26,313 23,609 CSUs related to deferred compensation for employees 12,437 16,571 20,467 Stock options 1,194,352 1,032,128 916,287 RSUs related to incentive compensation 816,759 834,981 823,393 Total 2,038,920 1,909,993 1,783,756 Director Common Stock Units Deferred compensation for Directors is in the form of CSUs, which represent an equal number of common shares to be issued in the future.

Statutory Information and Divid

Statutory Information and Dividend Restrictions	12 Months Ended

Insurance [Abstract]
Statutory Information and Dividend Restrictions	The insurance departments of various states in which the insurance subsidiaries of HMEC are domiciled recognize as net income and surplus those amounts determined in conformity with statutory accounting principles prescribed or permitted by the insurance departments, which differ in certain respects from GAAP. HMEC has principal insurance subsidiaries domiciled in Illinois, New York, Wisconsin and Texas. The statutory financial statements of these subsidiaries are prepared in accordance with accounting principles prescribed or permitted by the Illinois Department of Insurance, the New York Department of Financial Services, the Wisconsin Office of the Commissioner of Insurance and the Texas Department of Insurance, as applicable. Prescribed statutory accounting principles include a variety of publications of the NAIC, as well as state laws, regulations and general administrative rules. In converting from statutory to GAAP, typical adjustments include DAC, certain reinsurance transactions, the inclusion of statutory non-admitted assets and the inclusion of net unrealized investment gains or losses in shareholders' equity relating to fixed maturity securities. The following table includes selected information for HMEC's insurance subsidiaries: ($ in millions) Year Ended December 31, 2022 2021 2020 Consolidated net income, statutory basis $ 77.0 $ 114.8 $ 141.9 Consolidated capital and surplus, statutory basis (1) $ 1,024.5 $ 955.1 $ 937.3 (1) Subject to regulatory restrictions. The NAIC has risk-based capital guidelines to evaluate the adequacy of statutory capital and surplus in relation to risks assumed in investments, reserving policies, and volume and types of insurance business written. As of December 31, 2022 and 2021, the minimum statutory-basis capital and surplus required to be maintained by HMEC's insurance subsidiaries was $123.3 million and $123.0 million, respectively. As of December 31, 2022 and 2021, statutory capital and surplus of each of the Company's insurance subsidiaries was above required levels. The restricted net assets of HMEC's insurance subsidiaries wer e $28.6 million and $26.2 million as of December 31, 2022 and 2021, respectively. The minimum statutory basis capital and surplus amount at each date is the total estimated authorized control level risk-based capital for all of HMEC's insurance subsidiaries combined. Authorized control level risk-based capital represents the minimum level of statutory basis capital and surplus necessary before the insurance commissioner in the respective state of domicile is authorized to take whatever regulatory actions considered necessary to protect the best interests of the policyholders and creditors of the insurer. The amount of restricted net assets represents the combined fair value of securities on deposit with governmental agencies for the insurance subsidiaries as required by law in various states in which the insurance subsidiaries of HMEC conduct business. HMEC relies largely on dividends from its insurance subsidiaries to meet its obligations for payment of principal and interest on debt, dividends to shareholders and parent company operating expenses, including tax payments pursuant to tax sharing agreements. Payments for share repurchase programs also have this dependency. HMEC's insurance subsidiaries are subject to various regulatory restrictions which limit the amount of annual dividends or other distributions, including loans or cash advances, available to HMEC without prior approval of the insurance regulatory authorities. As a result, HMEC may not be able to receive dividends from such subsidiaries at times and in amounts necessary to pay desired dividends to shareholders.

Retirement Benefits [Abstract]
Retirement Plans and Other Postretirement Benefits	Retirement Plans and Other Postretirement BenefitsThe Company sponsors two qualified and three non-qualified retirement plans. Substantially all employees participate in the 401(k) plan. Both the qualified defined benefit plan and the two non-qualified supplemental defined benefit plans have been frozen since 2002. All participants in the frozen plans are 100% vested in their accrued benefit and all non-qualified supplemental defined benefit plan participants are receiving payments. Certain employees participate in a non-qualified defined contribution plan. Qualified Plans All employees participate in the 401(k) plan and receive a 100% vested 3% "safe harbor" company contribution based on employees' eligible earnings. The Company matches each dollar of employee contributions up to a 5% maximum — in addition to maintaining the automatic 3% "safe harbor" contribution. The matching company contribution vests after 5 years of service. The 401(k) plan is fully funded. The Company's policy for the frozen defined benefit plan is to contribute to the plan amounts which are actuarially determined to provide sufficient funding to meet future benefit payments as defined by federal laws and regulations. For the two qualified plans, all assets are held in their respective plan trusts. Non-qualified Plans The non-qualified plans were established for specific employees whose otherwise eligible earnings exceeded the statutory limits under the qualified plans. Benefit accruals under the non-qualified supplemental defined benefit plans were frozen in 2002 and all participants are currently in payment status. Both the non-qualified frozen supplemental defined benefit plans and the non-qualified contribution plan are unfunded plans with the Company's contributions made at the time payments are made to participants. Plan Expense Plan expense recognized for the non-qualified defined contribution, 401(k), defined benefit and supplemental retirement plans was $10.7 million, $9.2 million and $10.0 million for the years ended December 31, 2022, 2021 and 2020, respectively.

To set its discount rate, the Company looks to leading indicators, including the Mercer Above Mean Yield Curve. The assumption for the long-term rate of return on plan assets was determined by considering actual investment experience during the lifetime of the plan, balanced with reasonable expectations of future growth considering the various classes of assets and percentage allocation for each asset class. The Company has an investment policy for the defined benefit pension plan that aligns the assets within the plan's trust. Management believes this allocation will produce the targeted long-term rate of return on assets necessary for payment of future benefit obligations, while providing adequate liquidity for payments to current beneficiaries. Assets are reviewed against the defined benefit pension plan's investment policy and the trustee has been directed to adjust invested assets at least quarterly to maintain the target allocation percentages. Fair values of the equity security funds and fixed income funds have been determined from public quotations. The following table presents the fair value hierarchy for the Company's defined benefit pension plan assets, excluding cash held.

There were no Level 3 assets held during the years ended December 31, 2022 and 2021. In 2023, the Company expects amortization of net losses of $0.2 million and $0.2 million for the defined benefit plan and the supplemental retirement plans, respectively, and expects no amortization of prior service cost for the supplemental retirement plans to be included in net periodic pension expense. Postretirement Benefits Other than Pensions As of December 31, 2006, upon discontinuation of retiree medical benefits, Health Reimbursement Accounts (HRAs) were established for eligible participants and totaled $7.3 million. As of December 31, 2022, the balance of the previously established HRAs was $1.2 million. Funding of HRAs was $0.1 million, $0.0 million and $0.1 million for the years ended December 31, 2022, 2021 and 2020, respectively. 2023 Contributions In 2023, there is no minimum funding requirement for the Company's defined benefit plan.

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 Annual Report on Form 10-K, 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 $704.2 million and $858.1 million for the years ended December 31, 2022 and 2021, respectively.

Equity [Abstract]
Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss)	Comprehensive income (loss) represents the change in shareholders' equity during a reporting period from transactions and other events and circumstances from non-shareholder sources. For the Company, comprehensive income (loss) is equal to net income plus or minus the after tax change in net unrealized investment gains (losses) on fixed maturity securities and the after tax change in net funded status of benefit plans for the periods as shown in the Consolidated Statements of Changes in Shareholders' Equity. AOCI represents the accumulated change in shareholders' equity from these transactions and other events and circumstances from non-shareholder sources as shown in the Consolidated Balance Sheets. In the Consolidated Balance Sheets, the Company recognizes the net funded status of benefit plans as a component of AOCI, net of tax. Comprehensive Income (Loss) The components of comprehensive income (loss) were as follows: ($ in millions) Year Ended December 31, 2022 2021 2020 Net income (loss) $ (2.6) $ 142.8 $ 133.3 Other comprehensive income (loss): Change in net unrealized investment gains (losses) on fixed maturity securities: Net unrealized investment gains (losses) on securities arising during the period (885.3) (104.9) 184.0 Less: reclassification adjustment for net investment gains (losses) included in income before income tax (61.6) (8.5) 11.2 Total, before tax (823.7) (96.4) 172.8 Income tax expense (benefit) (176.1) (20.8) 36.9 Total, net of tax (647.6) (75.6) 135.9 Change in net funded status of benefit plans: Before tax 1.8 1.2 (0.5) Income tax expense (benefit) 0.4 0.2 (0.1) Total, net of tax 1.4 1.0 (0.4) Total comprehensive income (loss) $ (648.8) $ 68.2 $ 268.8 Accumulated Other Comprehensive Income (Loss) The following table reconciles the components of AOCI for the periods indicated.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company conducts and manages its business through four reporting segments. The three reporting 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 reporting segments, consistent with the basis for management's evaluation of the results of those reporting 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 also have included corporate debt retirement costs, when applicable. In 2021 and prior, the Company conducted and managed its business through five reporting segments. The four reporting segments representing the major lines of business, were: (1) Property & Casualty, (2) Supplemental, (3) Retirement, and (4) Life. The Company did not allocate the impact of corporate-level transactions to these reporting segments, consistent with the basis for management's evaluation of the results of those reporting segments, but classifies those items in the fifth reporting segment, Corporate & Other. The change in reporting segments in 2022 aligns with leadership assignments and how the Company makes operating decisions and assesses performance as well as maintaining discrete financial information to evaluate performance and allocate resources. Accordingly, the presentation of prior period reporting segment information has been reclassified to conform to the current year's presentation. The accounting policies of the reporting segments are the same as those described in Note 1. The Company accounts for intersegment transactions, primarily the allocation of operating and agency costs from Corporate & Other to Property & Casualty, Life & Retirement, and Supplemental & Group Benefits on a direct cost basis. Summarized financial information for these segments is as follows: ($ in millions) December 31, 2022 2021 2020 Net premiums and contract charges earned Property & Casualty $ 608.2 $ 617.4 $ 650.1 Life & Retirement 145.3 144.2 147.0 Supplemental & Group Benefits (1) 275.5 128.0 133.6 Total $ 1,029.0 $ 889.6 $ 930.7 Net investment income Property & Casualty $ 31.4 $ 61.1 $ 42.6 Life & Retirement 338.3 338.6 299.3 Supplemental & Group Benefits (1) 33.3 25.2 18.1 Corporate & Other — (0.1) (0.2) Intersegment eliminations (2.1) (2.3) (2.2) Total $ 400.9 $ 422.5 $ 357.6 Net income (loss) Property & Casualty $ (44.4) $ 57.0 $ 76.5 Life & Retirement 48.8 68.4 30.7 Supplemental & Group Benefits (1) 58.5 46.0 42.9 Corporate & Other (65.5) (28.6) (16.8) Total $ (2.6) $ 142.8 $ 133.3 ($ in millions) December 31, 2022 2021 2020 Assets Property & Casualty $ 1,083.8 $ 1,243.4 $ 1,324.9 Life & Retirement 10,858.3 12,068.6 11,243.2 Supplemental & Group Benefits (1) 1,396.1 854.9 811.5 Corporate & Other 173.4 281.8 182.3 Intersegment eliminations (64.8) (64.8) (90.1) Total $ 13,446.8 $ 14,383.9 $ 13,471.8 Additional significant financial information for these segments is as follows: ($ in millions) Years Ended December 31, 2022 2021 2020 DAC amortization expense Property & Casualty $ 64.3 $ 67.7 $ 74.4 Life & Retirement 32.8 25.5 23.8 Supplemental & Group Benefits (1) 1.6 1.5 1.7 Total $ 98.7 $ 94.7 $ 99.9 Income tax expense (benefit) Property & Casualty $ (13.8) $ 13.2 $ 15.4 Life & Retirement 6.6 13.6 4.6 Supplemental & Group Benefits (1) 16.1 12.6 12.0 Corporate & Other (18.2) (7.3) (5.7) Total $ (9.3) $ 32.1 $ 26.3 (1) Group Benefits was acquired effective January 1, 2022 and thus, comparison to amounts for the years ended December 31, 2021 and 2020 is not meaningful.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying audited consolidated financial statements have been prepared in accordance 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). 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, 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 certain investment contracts and policy reserves, valuation of long-duration contracts under the new accounting guidance in ASU 2018-12 and valuation of assets acquired and liabilities assumed under purchase accounting.
Investments	Investments Fixed Maturity Securities The Company invests predominantly in fixed maturity securities. Fixed maturity securities include bonds, asset-backed securities (ABS), mortgage-backed securities (MBS), other structured securities and redeemable preferred stocks. MBS includes residential and commercial mortgage-backed securities. Fixed maturity securities, which may be sold prior to their contractual maturity, are designated as available for sale (AFS) and are carried at fair value of which a portion represent securities that are hard-to-value. See Note 4 – Fair Value of Financial Instruments – Investments for a detailed description of how the Company estimates fair value for its fixed maturity securities portfolio including hard-to-value securities. An adjustment for net unrealized investment gains (losses) on all fixed maturity securities available for sale and carried at fair value, is recognized as a separate component of accumulated other comprehensive income (loss) (i.e., AOCI) within shareholders’ equity, net of applicable deferred taxes and the related impact on deferred policy acquisition costs (DAC) associated with annuity contracts and life insurance products with account values that would have occurred if the securities had been sold at their aggregate fair value and the proceeds reinvested at current yields. The Company excludes accrued interest receivable from the amortized cost basis of its AFS fixed maturity securities. Equity Securities Equity securities primarily include common stocks, exchange traded and mutual funds and non-redeemable preferred stocks. Certain exchange traded and mutual funds have fixed maturity securities as their underlying investments. Equity securities are carried at fair value and have readily determinable fair values. Limited Partnership Interests Investments in limited partnership interests are accounted for using the equity method of accounting (EMA) and include interests in commercial mortgage loan funds, private equity funds, infrastructure equity funds, real estate equity funds, infrastructure debt funds and other funds. Short-Term and Other Investments Short-term investments, including money market funds, commercial paper, U.S. Treasury bills and other short-term investments, are carried at fair value. Other investments primarily consist of policy loans, Federal Home Loan Bank of Chicago (FHLB) common stock, mortgage loans and derivatives. Policy loans are carried at unpaid principal balances. FHLB common stock is carried at cost. Mortgage loans are carried at amortized cost, net, which represent the amount expected to be collected. Derivatives are carried at fair value. Variable Interest Entities (VIEs) The Company invests in fixed maturity securities and alternative investment funds that could qualify as variable interests in VIEs, including corporate securities, ABS and MBS. Such variable interests in VIEs have been reviewed and the Company determined that those VIEs are not subject to consolidation as the Company is not the primary beneficiary because it does not have the power to direct the activities that most significantly impact those VIEs' economic performance. Net Investment Income Net investment income primarily consists of interest, dividends and income from limited partnership interests. Interest is recognized on an accrual basis using the effective yield method and dividends are recorded at the ex-dividend date. ABS and MBS interest income is determined considering estimated pay-downs, including prepayments, obtained from third-party data sources and internal estimates. Actual prepayment experience is periodically reviewed, and effective yields are recalculated when differences arise between the prepayments originally anticipated and the actual prepayments received and currently anticipated. For ABS and MBS of high credit quality with fixed interest rates, the effective yield is recalculated on a retrospective basis. For all others, the effective yield is generally recalculated on a prospective basis. Net investment income for AFS fixed maturity securities includes the impact of accreting the credit loss allowance for the time value of money. Accrual of income is suspended for fixed maturity securities when the timing and amount of cash flows expected to be received is not reasonably estimable. Accrual of income is suspended for commercial mortgage loans that are in default or when full and timely collection of principal and interest payments is not probable. Accrued investment income receivables are monitored for recoverability and when not expected to be collected, are written-off through net investment income. Cash receipts on investments on non-accrual status are generally recorded as a reduction of amortized cost or principal. Income from limited partnership interests is recognized based upon the changes in fair value of the investee’s equity primarily determined using its net asset value and is generally recognized on a three month delay due to the availability of the related financial statements of the investee. The Company reports accrued investment income separately from AFS fixed maturity securities and has elected not to measure an allowance for credit losses for accrued investment income. Accrued investment income is written-off and recognized as a net investment loss at the time the issuer of the security defaults or is expected to default on payments. Net Investment Gains (Losses) Net investment gains (losses) include gains and losses on investment sales, changes in the credit loss allowances related to fixed maturity securities and mortgage loans, impairments, valuation changes of equity securities and periodic changes in fair value and settlements of derivatives. Net investment gains (losses) on investment sales are determined on a specific identification basis and are net of credit losses already recognized through an allowance. Credit Loss Impairments for Fixed Maturity Securities For AFS fixed maturity securities, the difference between amortized cost, net of a credit loss allowance (i.e., amortized cost, net) and fair value, net of certain other items and deferred income taxes is reported as a component of AOCI on the Consolidated Balance Sheets and is not reflected in the operating results of any period until reclassified to net income upon the consummation of a transaction with an unrelated third party or when a credit loss allowance is recorded. The Company has a comprehensive portfolio monitoring process to evaluate fixed maturity securities (at the cusip/issuer level) on a quarterly basis that may require a credit loss allowance. These reviews, in conjunction with the Company's investment managers’ monthly credit reports and relevant factors such as (1) the financial condition and near-term prospects of the issuer; (2) the Company’s intent to sell a security or whether it is more likely than not that the Company will be required to sell a security before the anticipated recovery in value; (3) the market leadership of the issuer; (4) the debt ratings of the issuer; and (5) the cash flows and liquidity of the issuer or the underlying cash flows for ABS and MBS, are all considered in the impairment assessment. For each fixed maturity security in an unrealized loss position, the Company assesses whether management with the appropriate authority has made the decision to sell or whether it is more likely than not that the Company will be required to sell the security before the anticipated recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If a security meets either of these criteria, any existing credit loss allowance would be written-off against the amortized cost basis of the asset along with any remaining unrealized losses, with the incremental losses recorded as a net investment loss. If the Company has not made the decision to sell the fixed maturity security and it is not more likely than not that the Company will be required to sell the fixed maturity security before the anticipated recovery of its amortized cost basis, the Company evaluates whether it expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. The Company estimates the anticipated recovery value based on the best estimate of future cash flows considering past events, current conditions and reasonable and supportable forecasts. The estimated future cash flows are discounted at the security’s current effective rate and are compared to the amortized cost basis of the security. The determination of cash flow estimates is inherently subjective, and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security are considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, the remaining payment terms of the security, prepayment speeds, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, origination vintage year, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third-party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, sector credit ratings, financial condition of the bond insurer for insured fixed maturity securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate the anticipated recovery value if the Company determines that the security is dependent on the liquidation of collateral for ultimate settlement. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed maturity security, a credit loss allowance is recorded as a net investment loss for the shortfall in expected cash flows; however, the amortized cost basis, net of the credit loss allowance, may not be lower than the fair value of the security. The portion of the unrealized loss related to factors other than credit remains classified in AOCI. If the Company determines that the fixed maturity security does not have sufficient cash flows or other information to estimate a recovery value for the security, the Company may conclude that the entire decline in fair value is deemed to be credit related and the loss is recognized as a net investment loss. When a security is sold or otherwise disposed or the security is deemed uncollectible and written-off, the Company reverses amounts previously recognized in the credit loss allowance through net investment gains (losses). Recoveries after write-offs are recognized when received.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs The Company's DAC by reporting segment was as follows: ($ in millions) December 31, 2022 2021 Property & Casualty $ 24.5 $ 24.4 Life & Retirement 403.5 219.4 Supplemental & Group Benefits 5.1 4.2 Total $ 433.1 $ 248.0 DAC consists of commissions, policy issuance and other costs which are incremental and directly related to the successful acquisition of new or renewal business, which are deferred and amortized on a basis consistent with the type of insurance coverage. For property and casualty risks, DAC is amortized over the terms of the insurance policies (6 or 12 months). For all annuity contracts, DAC is amortized over 20 years in proportion to estimated gross profits. DAC is amortized in proportion to estimated gross profits over 20 years for certain life insurance products with account values and over 30 years for indexed universal life (IUL) products. For other individual life contracts, DAC is amortized in proportion to anticipated premiums over the terms of the insurance policies (10, 15, 20, 30 years). For supplemental and group benefit policies, DAC is amortized in proportion to anticipated premiums over the terms of the insurance policies (approximately 6 years, based on an estimated average duration across all supplemental and group benefit products). The Company periodically reviews the assumptions and estimates used in DAC and also periodically reviews its estimations of gross profits, a process sometimes referred to as "unlocking". The most significant assumptions that are involved in the estimation of annuity gross profits include interest rate spreads, future financial market performance, business surrender/lapse rates, expenses and the impact of net investment gains (losses) on fixed maturity and equity securities. For the variable deposit portion of retirement, the Company amortizes DAC utilizing a future financial market performance assumption of a gross 8% reversion to the mean approach with a 200 basis point corridor around the mean during the reversion period, representing a cap and a floor on the Company's long-term assumption. The Company's practice with regard to future financial market performance assumes that long-term appreciation in the financial markets is not changed by short-term market fluctuations, but is only changed when sustained deviations are experienced. The Company monitors these fluctuations and only changes the assumption when long-term expectations change. The most significant assumptions that are involved in the estimation of life insurance gross profits include interest rates expected to be received on investments, business persistency, and mortality. Conversions from term to permanent insurance cause an immediate write down of the associated DAC. The most significant assumptions that are involved in the estimation of supplemental gross profits include morbidity, persistency, expenses and interest rates expected to be received on investments. When a supplemental policy lapses, there is an immediate write down of the associated DAC. Annually, the Company performs a gross premium valuation (GPV) on life insurance policies to assess whether a loss recognition event has occurred. This involves discounting expected future benefits and expenses less expected future premiums. To the extent that this amount is greater than the liability for future benefits less the DAC asset, in aggregate for the life insurance block, a loss would be recognized by first writing-off the DAC asset and then increasing the liability.
Intangible Assets, net	Intangible Assets, net The value of business acquired (VOBA) associated with the acquisitions of NTA Life Enterprises, LLC (NTA) and Madison National Life Insurance Company, Inc. (Madison National) represents the difference between the fair value of insurance contracts and insurance policy reserves measured in accordance with the Company's accounting policy for insurance contracts acquired. VOBA was based on an actuarial estimate of the present value of future distributable earnings for insurance in force on the acquisition date. VOBA net of accumulated amortization was $70.5 million as of December 31, 2022 and is being amortized by product based on the present value of future premiums to be received. The Company estimates that it will recognize VOBA amortization of $5.8 million in 2023, $5.4 million in 2024, $5.1 million in 2025, $4.7 million in 2026 and $4.4 million in 2027. The Company accounts for the value of distribution acquired (VODA) associated with the acquisition of NTA based on an actuarial estimate of the present value of future business to be written by the existing distribution channel. VODA net of accumulated amortization was $38.9 million as of December 31, 2022 and is being amortized on a straight-line basis. The Company estimates that it will recognize VODA amortization of $2.9 million in each of the years 2023 through 2027, respectively. The Company accounts for VODA associated with the acquisition of BCG Securities, Inc. (BCGS) based on management's estimate of the present value of future business to be written by the existing distribution channel. VODA net of accumulated amortization was $0.5 million as of December 31, 2022 and is being amortized based on the present value of future profits to be received. The cumulative amortization the Company expects to recognize for the years 2023 through 2027 is insignificant. The Company accounts for the value of agency relationships based on the present value of commission overrides retained by NTA. Agency relationships net of accumulated amortization was $8.8 million as of December 31, 2022 and is being amortized based on the present value of future premiums to be received. The Company estimates that it will recognize agency relationships amortization of $1.6 million in 2023, $1.4 million in 2024, $1.2 million in 2025, $1.0 million in 2026 and $0.9 million in 2027. The Company accounts for the value of customer relationships based on the present value of expected profits from existing Benefit Consultants Group, Inc. (BCG) and Madison National customers in force at the date of acquisition. Customer relationships net of accumulated amortization was $53.2 million as of December 31, 2022 and is being amortized based on the present value of future profits to be received for BCG and based on the present value of future premiums for Madison National. The Company estimates that it will recognize customer relationships amortization of $4.6 million in 2023, $4.9 million in 2024, $5.2 million in 2025, $5.6 million in 2026 and $6.0 million in 2027. The trade names intangible asset represents the present value of future savings accruing to NTA, BCG and BCGS by virtue of not having to pay royalties for the use of the trade names, valued using the relief from royalty method. The state licenses intangible asset represents the regulatory licenses held by NTA and Madison National that were valued using the cost approach. Both the trade names and state licenses are indefinite-lived intangible assets that are not subject to amortization. Annually, the Company performs a VOBA analysis on supplemental insurance policies to assess whether a loss recognition event has occurred. This initially involves comparing the historical and expected future experience on the block to the assumptions embedded in the original VOBA intangible asset. If both the experience to date and current expected experience are consistently better than the initial VOBA assumptions, the remaining value in the block is sufficient to support the VOBA intangible asset and no loss recognition is necessary. If the historical and current expected assumptions are not uniformly better than the initial VOBA assumptions, a GPV is performed to assess whether a loss recognition event has occurred. This involves discounting expected future benefits and expenses less expected future premiums. To the extent that this amount is greater than the liability for future benefits less the VOBA intangible asset, in aggregate for the supplemental insurance block, a loss would be recognized by first writing-off the VOBA and then increasing the liability. Currently, a GPV is not required for the acquired supplemental block. No such costs were deemed unrecoverable during the year ended December 31, 2022. Amortizing intangible assets (i.e., VODA, agency relationships and customer relationships) are tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. The carrying amount of an amortizing intangible asset is not recoverable if it exceeds the sum of undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount is not recoverable from undiscounted cash flows, the impairment is measured as the difference between the carrying amount and fair value. Intangible assets that are not subject to amortization (i.e., trade names and state licenses) are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of an intangible asset that is not subject to amortization exceeds its fair value, an impairment loss is recognized in an amount equal to the excess. As of October 1, 2022, the Company performed a qualitative assessment to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessment of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset is less than its carrying amount with the exception of lower than anticipated BCG revenues which triggered a requirement to evaluate the intangible assets associated with BCG. For the evaluation, the fair value of BCG's intangible assets were measured using discounted cash flow methods. The carrying amounts for customer relationships and trade names exceeded the fair values resulting in a $2.5 million intangible asset impairment charge for customer relationships and a $0.3 million intangible asset impairment charge for trade names. As of October 1, 2021, the Company performed both qualitative assessments and quantitative impairment tests for intangible assets and concluded that no impairments were warranted. As of October 1, 2020, the Company performed qualitative assessments to determine whether it was necessary to perform quantitative intangible asset impairment tests. Based on the assessments of qualitative factors, there were no events or circumstances that led to a determination that it is more likely than not that the fair value of an intangible asset was less than its carrying amount with the exception of VODA and trade names intangible assets assigned to BCGS, for which quantitative intangible asset impairment tests were performed that resulted in intangible asset impairment charges of $4.4 million in aggregate.
Goodwill	Goodwill When the Company was acquired from CIGNA Corporation by HME Holdings, Inc. in 1989, goodwill was recognized in the application of purchase accounting. In 1994, goodwill was recognized with respect to the acquisition of Horace Mann Property & Casualty Insurance Company. In 2019, goodwill was recognized with respect to the acquisitions of BCG, BCGS and NTA. In 2022, goodwill was recognized with respect to the acquisition of Madison National. Goodwill represents the excess of the amounts paid to acquire a business over the fair value of its net assets at the date of acquisition. Goodwill is not amortized, but is tested for impairment at the reporting unit level at least annually or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. A reporting unit is defined as an operating segment or a business unit one level below an operating segment, if separate financial information is prepared and regularly reviewed by management at that level. The Company's reporting units, for which goodwill has been allocated, are Property & Casualty, Life, BCG, BCGS, Supplemental and Group Benefits. Refer to Note 7 for the allocation of goodwill by reporting segment as of December 31, 2022. The goodwill impairment test, as defined in GAAP, allows an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the entity performs a quantitative goodwill impairment test by comparing the fair value of a reporting unit to its carrying amount for purposes of confirming and measuring an impairment. Goodwill impairment is the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. Any amount of goodwill determined to be impaired is recognized as an expense in the period in which the impairment determination is made.
Property and Equipment	Property and EquipmentProperty and equipment is carried at cost less accumulated depreciation, which is calculated using the straight-line method and based on the estimated useful lives of the assets. The estimated life for real estate is identified by specific property and range from 20 to 45 years. The estimated useful lives of leasehold improvements and other property and equipment, including capitalized software, generally range from 3 to 10 years.
Separate Account Variable Annuity Assets and Liabilities	Separate Account Variable Annuity Assets and Liabilities Separate Account variable annuity assets represent contractholder funds invested in various mutual funds. The Separate Account variable annuity assets comprise actively traded mutual funds that have daily quoted net asset values that are readily determinable for identical assets that the Company can access. Net asset values for the actively traded mutual funds in which the Separate Account variable annuity assets are invested are obtained daily from the fund managers. Separate Account variable annuity liabilities are equal to the estimated fair value of Separate Account variable annuity assets. The investment income, gains and losses of these accounts accrue directly to the contractholders and are not included in the results of operations of the Company. The activity of the Separate Accounts is not reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss) except for (1) contract charges earned, (2) the activity related to contract guarantees, which are benefits on existing variable annuity contracts, and (3) the impact of financial market performance on the amortization of DAC. The Company's contract charges earned include fees charged to the Separate Accounts, including mortality charges, risk charges, policy administration fees, investment management fees and surrender charges.
Investment Contract and Policy Reserves	Investment Contract and Policy Reserves Liabilities for future benefits on supplemental, life and annuity policies are established in amounts adequate to meet the estimated future obligations on policies in force. Liabilities for future policy benefits on certain supplemental and life insurance policies are computed using the net level premium method including assumptions as to investment yields, mortality, morbidity, persistency, expenses and other assumptions based on the Company's experience, including a provision for adverse deviation. These assumptions are established at the time the policy is issued and are intended to estimate the experience for the period the policy benefits are payable. If experience is less favorable than the assumptions, additional liabilities may be established, resulting in recognition of a loss for that period. Liabilities for future benefits on annuity contracts and certain long-duration life insurance contracts are carried at accumulated policyholder values without reduction for potential surrender or withdrawal charges. The liability also includes provisions for the unearned portion of certain policy charges.
Reserves for Fixed Indexed Annuities and Indexed Universal Life Products	Reserves for Fixed Indexed Annuities and Indexed Universal Life Products The Company offers fixed indexed annuity (FIA) products with interest crediting strategies linked to the Standard & Poor's (S&P) 500 Index and the Dow Jones Industrial Average (DJIA). The Company purchases call options on the applicable indices as an investment to provide the income needed to fund the annual index credits on the indexed products. These products are deferred fixed annuities with a guaranteed minimum interest rate plus a contingent return based on equity market performance and are considered hybrid financial instruments under GAAP. The Company elected to not use hedge accounting for derivative transactions. As a result, the Company accounts for the purchased call options and the embedded derivative related to the provision of a contingent return at fair value, with changes in fair value recognized as Net investment gains (losses) in the Consolidated Statements of Operations and Comprehensive Income (Loss). The embedded derivative is bifurcated from the host contract and included in Other policyholder funds in the Consolidated Balance Sheets. The host contract is accounted for as a debt instrument in accordance with GAAP and is included in Investment contract and life policy reserves in the Consolidated Balance Sheets with any discount to the minimum account value being accreted using the effective yield method. In the Consolidated Statements of Operations and Comprehensive Income (Loss), accreted interest for FIA products and benefit claims on these products incurred during the reporting period are included in Benefits, claims and settlement expenses. The Company offers indexed universal life (IUL) products as part of its product portfolio with interest crediting strategies linked to the S&P 500 Index and the DJIA as well as a fixed option. The Company purchases call options monthly to economically hedge the potential liabilities arising in IUL accounts. As a result, the Company records the purchased call options and the embedded derivative related to the provision of a contingent return at fair value, with changes in fair value reported in Net investment gains (losses) in the Consolidated Statements of Operations and Comprehensive Income (Loss). IUL policies with a balance in one or more indexed accounts are considered to have an embedded derivative. The benefit reserve for the host contract is measured using the retrospective deposit method, which for Horace Mann's IUL product is equal to the account balance. The embedded derivative is bifurcated from the host contract, carried at fair value, and included in Investment contract and life policy reserves in the Consolidated Balance Sheets. See Note 4 for more information regarding the determination of fair value for derivatives embedded in FIA and IUL and purchased call options.
Unpaid Claims and Claim Expense Reserves	Unpaid Claims and Claim Expense Reserves Liabilities for Property & Casualty unpaid claims and claim expense reserves (reserves) include provisions for payments to be made on reported claims, claims incurred but not yet reported (IBNR) and associated settlement expenses. All of the Company's reserves for Property & Casualty unpaid claims and claim expenses are carried at the full value of estimated liabilities and are not discounted for interest expected to be earned on the reserves. Estimated amounts of salvage and subrogation on unpaid Property & Casualty claims are deducted from the liability for unpaid claims. Due to the nature of the Company's personal lines business, the Company has no exposure to losses related to claims for toxic waste cleanup, other environmental remediation or asbestos-related illnesses other than claims under property insurance policies for environmentally related items such as mold.
Other Policyholder Funds	Other Policyholder Funds Other policyholder funds includes payout annuity contracts without life contingencies and dividend accumulations, as well as balances outstanding under funding agreements with the Federal Home Loan Bank of Chicago (FHLB) and embedded derivatives related to FIA products. Except for embedded derivatives, each of these components is carried at cost. Embedded derivatives are carried at fair value. Amounts received and
Reinsurance	Reinsurance The Company enters into reinsurance arrangements pursuant to which it cedes certain insurance risks to unaffiliated reinsurers. Cessions under reinsurance agreements do not discharge the Company's obligations as the primary insurer. The accounting for reinsurance arrangements depends on whether the arrangement provides indemnification against loss or liability relating to insurance risk in accordance with GAAP. If the Company determines that a reinsurance agreement exposes the reinsurer to a reasonable possibility of a significant loss from insurance risk, the ceded unearned premiums and reinsurance balances recoverable on paid and unpaid losses and settlement expenses are reported separately as assets, instead of being netted with the related liabilities, since reinsurance does not relieve the Company of its legal liability to its policyholders. See Note 9 for further details. If the Company determines that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, the Company recognizes the reinsurance agreement using the deposit method of accounting. The assets transferred to the reinsurer as consideration paid is reported as a Deposit asset on reinsurance on the Company's Consolidated Balance Sheets. As amounts are received or paid or received, consistent with the underlying reinsured contracts, the Deposit asset on reinsurance is adjusted. The Deposit asset on reinsurance is accreted to the estimated ultimate cash flows using the interest method and the adjustment is reported as Net investment income. See Note 6 for further details.
Insurance Premiums and Contract Charges Earned	Insurance Premiums and Contract Charges Earned Property & Casualty insurance premiums are recognized as revenue ratably over the related contract periods in proportion to the risks insured. The unexpired portions of these Property & Casualty premiums are recorded as unearned premiums, using the monthly pro rata method. Premiums and contract charges for life insurance contracts with account values and annuity contracts consist of charges for the cost of insurance, policy administration and withdrawals. Premiums for traditional life and supplemental and group policies are recognized as revenues when due over the premium-paying period. Contract deposits to annuity contracts and life insurance contracts with account values represent funds deposited by policyholders and are not included in the Company's premiums or contract charges earned.
Share-Based Compensation	Share-Based Compensation The Company grants stock options and both service-based and performance-based restricted common stock units (RSUs) to executive officers, other employees and Directors in an effort to attract and retain individuals
Income Taxes	Income Taxes The Company uses the asset and liability method for calculating deferred federal income taxes. Income tax provisions are generally based on income reported for financial statement purposes. The provisions for federal income taxes for the years ended December 31, 2022, 2021 and 2020 included amounts currently payable and deferred income taxes resulting from the cumulative differences in the Company's assets and liabilities, determined on a tax return versus financial statement basis. Deferred tax assets and liabilities include provisions for net unrealized investment gains (losses) on fixed maturity securities as well as the net funded status of benefit plans with the changes for each period included in the respective components of AOCI within shareholders' equity.
Earnings Per Share	Earnings Per ShareBasic earnings per share is computed based on the weighted average number of common shares outstanding plus the weighted average number of fully vested RSUs and common stock units (CSUs) payable as shares of HMEC common stock. Diluted earnings per share is computed based on the weighted average number of common shares and common stock equivalents outstanding, to the extent dilutive.
Consolidated Statements of Cash Flows	Consolidated Statements of Cash FlowsFor purposes of the Consolidated Statements of Cash Flows, cash constitutes cash on deposit at banks as well as restricted cash.
Future Adoption of New Accounting Standards	Future 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, further amended by ASU 2019-09, Effective Date, Financial Services – Insurance (Topic 944), and ASU 2020-11, Effective Date and Early Application, Financial Services – Insurance (Topic 944). This update will change 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 DAC, and 4) enhanced financial statement presentation and disclosures. This guidance will be effective for the Company for interim and annual periods beginning after December 15, 2022. The Company will adopt the guidance in the first quarter of 2023 using a modified retrospective approach for LFPB and DAC. MRBs will be adopted utilizing a retrospective method. LFPB and DAC When measuring LFPB, long-duration contracts issued by the Company will be grouped into calendar-year cohorts based on the contract issue date and product type. The Company has made an entity-wide election to not update expense assumptions when updating cash flow assumptions. Cash flows will be discounted using duration-specific forward rates from Single-A rated fixed income instruments. For liability cash flows that are projected beyond the duration of market-observable level yields for upper-medium-grade (low credit risk) fixed income instruments, the Company uses the last market-observable level yield and use linear interpolation to determine yield assumptions for durations that do not have market-observable yields. DAC will be grouped into calendar-year cohorts, consistent with the cohorts utilized in measuring the LFPB for the corresponding contracts. DAC will be amortized on a constant level basis over the expected term of the corresponding contracts. MRBs The Company’s existing variable annuity contracts include Guaranteed Minimum Death Benefits (GMDB). GMDBs are MRBs under ASU 2018-12 and will be measured at fair value with changes in fair value recognized in income, except for changes in instrument-specific credit risk which will be recorded in other comprehensive income. The Company’s instrument-specific credit risk will be determined using observable market data for Company debt. Implementation Progress and Transition Adjustment - LFPB The Company currently estimates that the January 1, 2021 transition date impact from adoption will result in a decrease in AOCI of $499.3 million. This is due primarily to updating the LFPB discount rate assumptions previously locked-in for reserves held at the transition date to rates determined by reference to the transition date market level yields for upper-medium-grade (low credit risk) fixed income instruments as of December 31, 2020. The Company had five cohorts where the net premium ratio was capped at 100% at the transition date, resulting in a reduction to retained earnings of $0.2 million. The Company estimates the effect from adoption because of the update of underlying assumptions, including the removal of the provision for adverse deviation, will increase income after-tax by $7 million to $17 million and $15 million to $25 million for the years ended December 31, 2022 and 2021, respectively. Implementation Progress and Transition Adjustment - DAC The Company currently estimates that the January 1, 2021 transition date impact from adoption will result in an increase in AOCI of $71.5 million. This is due to the removal of amounts previously recognized in AOCI (shadow DAC adjustments). The Company estimates the effect of amortizing on a constant-level basis over the expected term of the related contracts will increase income after-tax by $8 million to $10 million and $3 million to $4 million for the years ended December 31, 2022 and 2021, respectively. Implementation Progress and Transition Adjustment – MRBs Under the retrospective method of adoption, the Company currently estimates that the January 1, 2021 transition date impact from adoption will result in a decrease to AOCI of $1.3 million and a decrease to retained earnings of $5.4 million. The effect of changes in the instrument-specific credit risk between the MRBs contract issue date and the transition date is recognized in AOCI. The remaining difference between the fair value and the carryover basis at the transition date is recognized as an adjustment to opening retained earnings. To determine the terms of each MRB at contract issuance, the Company maximized the use of relevant observable information as of contract issuance. However, the Company determined that it did not have relevant observable information as of contract issuance for all individual assumptions for every MRB, particularly related to mortality, lapse and premium payment assumptions for MRBs issued prior to 2006. For those individual assumptions without relevant observable information at contract issuance, the Company used hindsight and historical experience. The Company estimates the change in fair value except for changes in instrument-specific credit risk will increase income after-tax by $0 million to $4 million and $2 million to $6 million for the years ended December 31, 2022 and 2021, respectively. The Company estimates that the change in instrument-specific credit risk will result in increases (decreases) to AOCI of $(3) million to $3 million and $(7) million to $(1) million for the years ended December 31, 2022 and 2021, respectively. Implementation Progress – Overall The Company has not completed its implementation process for the years ended December 31, 2022 and 2021, including the finalization of the design and implementation of relevant key controls. The Company expects to continue to refine these key controls until implementation in the first quarter of 2023, which could drive variability

Summary of Fair Value and Gross Unrealized Losses of Fixed Maturity Securities and Equity Securities in an Unrealized Loss Position	The following table presents the fair value and gross unrealized losses for fixed maturity securities in an unrealized loss position as of December 31, 2022 and 2021. The Company views the decrease in fair value of all fixed maturity securities with unrealized losses as of December 31, 2022 — 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 December 31, 2022, 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 anticipated recovery in value. There has been a significant increase in interest rates since December 31, 2021, driven mostly by increases in U.S. Treasury rates, though credit spreads also widened. The 10-year U.S. Treasury yield increased 236 basis points for the year ended December 31, 2022, rising from 1.51% as of December 31, 2021 to 3.87% as of December 31, 2022. Additionally, credit spreads widened during the same time period, with investment grade and high yield wider by 40 and 171 basis points, respectively. These upward movements in rates caused market yields in the Company's portfolios to rise sharply, with downward pressure on prices. Investment grade and high yield total returns for the year ended December 31, 2022 were down 15.4% and 11.2%, respectively. The Bloomberg Barclays Index Yield-to-Worst for Investment Grade rose 3.1% for the year ended December 31, 2022, ending at 5.4%, while the High Yield Index rose 4.8% to 9.0%. The Company's 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 December 31, 2022.
