Organization, Consolidation and Presentation of Financial Statements [Abstract]
BUSINESS AND BASIS OF PRESENTATION	BUSINESS AND BASIS OF PRESENTATION CNO Financial Group, Inc., a Delaware corporation ("CNO"), is a holding company for a group of insurance companies that develop, market and administer health insurance, annuity, individual life insurance and other insurance products. The terms "CNO Financial Group, Inc.", "CNO", the "Company", "we", "us", and "our" as used in these financial statements refer to CNO and its subsidiaries. Such terms, when used to describe insurance business and products, refer to the insurance business and products of CNO's insurance subsidiaries. We focus on serving middle-income pre-retiree and retired Americans, which we believe are attractive, underserved, high growth markets. We sell our products through exclusive agents, independent producers (some of whom sell one or more of our product lines exclusively) and direct marketing. Our unaudited consolidated financial statements reflect normal recurring adjustments that, in the opinion of management, are necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented. As permitted by rules and regulations of the Securities and Exchange Commission (the "SEC") applicable to quarterly reports on Form 10-Q, we have condensed or omitted certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Results for interim periods are not necessarily indicative of the results that may be expected for a full year. The December 31, 2023 consolidated balance sheet data was derived from the audited consolidated financial statements included in our 2023 Annual Report on Form 10-K. Accordingly, these interim consolidated financial statements should be read together with the consolidated financial statements included in our 2023 Annual Report on Form 10-K. When we prepare financial statements in conformity with GAAP, we are required to make estimates and assumptions that significantly affect reported amounts of various assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting periods. For example, we use significant estimates and assumptions to calculate values for deferred acquisition costs, the present value of future profits, fair value measurements of certain investments (including derivatives), allowance for credit losses and other-than-temporary impairments of investments, assets and liabilities related to income taxes, liabilities for insurance products, liabilities related to litigation and guaranty fund assessment accruals. If our future experience differs from these estimates and assumptions, our financial statements could be materially affected. The accompanying financial statements are unaudited and include the accounts of the Company and its subsidiaries. Our consolidated financial statements exclude transactions between us and our consolidated affiliates, or among our consolidated affiliates.

Accounting Policies [Abstract]
RECENTLY ISSUED ACCOUNTING STANDARDS	RECENTLY ISSUED ACCOUNTING STANDARDS In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. Such requirements include: (i) disclosures on significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss on an annual and interim basis; (ii) disclosures of an amount for other segment items by reportable segment and a description of its composition on an annual and interim basis (the other segment items category is the difference between segment revenues less the segment expenses disclosed pursuant to the new guidance); (iii) providing all annual disclosures on a reportable segment’s profit or loss and assets currently required by FASB ASC Topic 280, Segment Reporting in interim periods; and (iv) specifying the title and position of the CODM and an explanation of how the CODM uses the reported measures to assess segment performance and make decisions about allocating resources. ASU 2023-07 is effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, to be applied on a retrospective basis (with early adoption permitted). The adoption of ASU 2023-07 will expand our disclosures but will not have an impact on our financial position or results of operations. In December 2023, the FASB issued Accounting Standards Update 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 is intended to improve the effectiveness of income tax disclosures by requiring, among other things, the disclosure on an annual basis of: (i) specific categories in the rate reconciliation; and (ii) additional information for reconciling items that meet a quantitative threshold. In addition, ASU 2023-09 requires disclosure (on an annual basis) of the following information about income taxes paid: (i) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; and (ii) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). ASU 2023-09 is effective for annual periods beginning January 1, 2025, to be applied prospectively with an option for retrospective application (with early adoption permitted). The adoption of ASU 2023-09 will modify our disclosures but will not have an impact on our financial position or results of operations.

INVESTMENTS

Investments, Debt and Equity Securities [Abstract]
INVESTMENTS	INVESTMENTS We classify our fixed maturity securities into one of two categories: (i) "available for sale" (which we carry at estimated fair value with any unrealized gain or loss, net of any allowance for credit losses and income taxes, recorded as a component of shareholders' equity); or (ii) "trading" (which we carry at estimated fair value with changes in such value recognized as either net investment income (classified as investment income from policyholder and other special-purpose portfolios) or investment gains (losses)). Trading securities include: (i) investments purchased with the intent of selling in the near term to generate income; and (ii) certain fixed maturity securities containing embedded derivatives for which we have elected the fair value option. The change in fair value of the income generating investments is recognized in income from policyholder and other special-purpose portfolios (a component of net investment income). The change in fair value of securities with embedded derivatives is recognized in other investment gains (losses). We review our available for sale fixed maturity securities with unrealized losses to determine whether such impairments are the result of credit losses. We analyze various factors to make such determinations including, but not limited to: (i) actions taken by rating agencies; (ii) default by the issuer; (iii) the significance of the decline; (iv) an assessment of our intent to sell the security before recovering the security's amortized cost; (v) an economic analysis of the issuer's industry; and (vi) the financial strength, liquidity, and recoverability of the issuer. We perform a security by security review each quarter to evaluate whether a credit loss has occurred. In determining the credit loss component, we discount the estimated cash flows on a security by security basis. We consider the impact of macroeconomic conditions on inputs used to measure the amount of credit loss. For most structured securities, cash flow estimates are based on bond-specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity, prepayment speeds and structural support, including overcollateralization, excess spread, subordination and guarantees. For corporate bonds, cash flow estimates are derived by considering asset type, rating, time to maturity, and applying an expected loss rate. If a portion of the decline is due to credit-related factors, we separate the credit loss component of the impairment from the amount related to all other factors. The credit loss component is recorded as an allowance and reported in other investment gains (losses) (limited to the difference between estimated fair value and amortized cost). The impairment related to all other factors (non-credit factors) is reported in accumulated other comprehensive income (loss) along with unrealized gains (losses) related to fixed maturity investments, available for sale, net of tax and related adjustments. The allowance is adjusted for any additional credit losses and subsequent recoveries. When recognizing an allowance associated with a credit loss, the cost basis is not adjusted. When we determine a security is uncollectable, the remaining amortized cost will be written off. If we intend to sell an impaired fixed maturity security, available for sale, or identify an impaired fixed maturity security, available for sale, for which it is more likely than not we will be required to sell before anticipated recovery, the difference between the fair value and the amortized cost is included in other investment gains (losses) and the fair value becomes the new amortized cost. The new cost basis is not adjusted for any subsequent recoveries in fair value. The Company reports accrued investment income separately from fixed maturities, available for sale, and has elected not to measure an allowance for credit losses for accrued investment income. Accrued investment income is written off through net investment income at the time the issuer of the bond defaults or is expected to default on payments. At June 30, 2024, the amortized cost, gross unrealized gains, gross unrealized losses, allowance for credit losses and estimated fair value of fixed maturities, available for sale, were as follows (dollars in millions): Amortized cost Gross unrealized gains Gross unrealized losses Allowance for credit losses Estimated fair value Corporate securities $ 13,450.7 $ 43.4 $ (1,667.4) $ (38.6) $ 11,788.1 Certificates of deposit 470.2 3.5 — — 473.7 United States Treasury securities and obligations of United States government corporations and agencies 278.6 — (22.1) — 256.5 States and political subdivisions 3,192.5 18.6 (399.7) (.6) 2,810.8 Foreign governments 101.1 .4 (13.3) (.5) 87.7 Asset-backed securities 1,552.2 4.5 (87.9) (.1) 1,468.7 Agency residential mortgage-backed securities 787.3 6.1 (4.0) — 789.4 Non-agency residential mortgage-backed securities 1,667.2 30.4 (144.8) — 1,552.8 Collateralized loan obligations 1,227.6 5.1 (7.8) — 1,224.9 Commercial mortgage-backed securities 2,378.7 1.2 (214.6) — 2,165.3 Total fixed maturities, available for sale $ 25,106.1 $ 113.2 $ (2,561.6) $ (39.8) $ 22,617.9 At December 31, 2023, the amortized cost, gross unrealized gains, gross unrealized losses, allowance for credit losses and estimated fair value of fixed maturities, available for sale, were as follows (dollars in millions): Amortized cost Gross unrealized gains Gross unrealized losses Allowance for credit losses Estimated fair value Corporate securities $ 13,186.9 $ 74.7 $ (1,382.4) $ (41.7) $ 11,837.5 United States Treasury securities and obligations of United States government corporations and agencies 207.6 .1 (13.3) — 194.4 States and political subdivisions 2,896.8 31.3 (360.7) (.7) 2,566.7 Foreign governments 92.7 1.2 (10.4) (.4) 83.1 Asset-backed securities 1,476.2 4.1 (107.8) (.1) 1,372.4 Agency residential mortgage-backed securities 639.0 9.5 (.5) — 648.0 Non-agency residential mortgage-backed securities 1,670.1 35.8 (152.7) — 1,553.2 Collateralized loan obligations 1,042.5 3.3 (13.0) — 1,032.8 Commercial mortgage-backed securities 2,487.4 .7 (270.0) — 2,218.1 Total fixed maturities, available for sale $ 23,699.2 $ 160.7 $ (2,310.8) $ (42.9) $ 21,506.2 The following table sets forth the amortized cost and estimated fair value of fixed maturities, available for sale, at June 30, 2024, by contractual maturity. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without penalties. Structured securities (such as asset-backed securities, agency residential mortgage-backed securities, non-agency residential mortgage-backed securities, collateralized loan obligations and commercial mortgage-backed securities, collectively referred to as "structured securities") frequently include provisions for periodic principal payments and permit periodic unscheduled payments.

Accordingly, we may sell securities at a gain or a loss to enhance the projected total return of the portfolio as market opportunities change, to reflect changing perceptions of risk, or to better match certain characteristics of our investment portfolio with the corresponding characteristics of our insurance liabilities.

While we do not have the intent to sell securities with unrealized losses and it is not more likely than not that we will be required to sell securities with unrealized losses prior to their anticipated recovery, our intent on an individual security may change, based upon market or other unforeseen developments. In such instances, if a loss is recognized from a sale subsequent to a balance sheet date due to these unexpected developments, the loss is recognized in the period in which we had the intent to sell the security before its anticipated recovery.

Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Payment terms specified for mortgage loans may include a prepayment penalty for unscheduled payoff of the investment. Prepayment penalties are recognized as investment income when received. The allowance for estimated credit losses is measured using a loss-rate method on an individual asset basis. Inputs used include asset-specific characteristics, current economic conditions, historical loss information and reasonable and supportable forecasts about future economic conditions. The mortgage loan balance was comprised of commercial and residential mortgage loans. At June 30, 2024, we held commercial mortgage loan investments with an amortized cost and fair value of $1,487.2 million and $1,315.6 million, respectively. At June 30, 2024, there were no commercial mortgage loans that were noncurrent or in the process of foreclosure. At June 30, 2024, we held residential mortgage loan investments with an amortized cost and fair value of $702.0 million and $704.9 million, respectively. At June 30, 2024, there were twenty-three residential mortgage loans that were noncurrent with an amortized cost of $14.3 million (of which, fifteen loans with an amortized cost of $6.6 million were in foreclosure). The following table provides the amortized cost by year of origination and estimated fair value of our outstanding commercial mortgage loans and the underlying collateral as of June 30, 2024 (dollars in millions): Estimated fair Loan-to-value ratio (a) 2024 2023 2022 2021 2020 Prior Total amortized cost Commercial mortgage loans Collateral Less than 60% $ 65.0 $ 160.4 $ 159.9 $ 111.7 $ 32.9 $ 511.9 $ 1,041.8 $ 928.5 $ 3,934.4 60% to less than 70% 16.3 126.9 72.1 29.0 5.4 17.6 267.3 245.1 410.9 70% to less than 80% — 19.2 30.0 — — 35.2 84.4 67.4 114.9 80% to less than 90% — — 47.8 — — 45.9 93.7 74.6 111.8 Total $ 81.3 $ 306.5 $ 309.8 $ 140.7 $ 38.3 $ 610.6 $ 1,487.2 $ 1,315.6 $ 4,572.0 ________________ (a) Loan-to-value ratios are calculated as the ratio of: (i) the amortized cost of the commercial mortgage loans; to (ii) the estimated fair value of the underlying collateral.

(b) Changes in the estimated fair value of equity securities (that are still held as of the end of the respective periods) were $(0.7) million and $(0.5) million in the three months ended June 30, 2024 and 2023, respectively, and were $0.3 million and $0.1 million for the six months ended June 30, 2024 and 2023, respectively. (c) Changes in the estimated fair value of trading securities that we have elected the fair value option (that are still held as of the end of the respective periods) were nil and $(3.1) million in the three months ended June 30, 2024 and 2023, respectively, and were $4.7 million and $(5.6) million in the six months ended June 30, 2024 and 2023, respectively. During the first six months of 2024, we recognized net investment losses of $9.4 million, which were comprised of: (i) $36.2 million of net losses from the sales of investments; (ii) $0.1 million of gains related to equity securities, including the change in fair value; (iii) $17.1 million of gains related to certain other invested assets and fixed maturity investments with embedded derivatives, including the change in fair value; (iv) the increase in fair value of embedded derivatives related to a modified coinsurance agreement of $0.2 million; (v) $3.8 million of gains related to the liquidation of a VIE; and (vi) a decrease in the allowance for credit losses of $5.6 million. During the first six months of 2023, we recognized net investment losses of $49.9 million, which were comprised of: (i) $35.8 million of net losses from the sales of investments; (ii) $0.2 million of losses related to equity securities, including the change in fair value; (iii) the decrease in fair value of certain other invested assets and fixed maturity investments with embedded derivatives of $2.2 million; (iv) the decrease in fair value of embedded derivatives related to a modified coinsurance agreement of $0.3 million; and (v) an increase in the allowance for credit losses of $11.4 million. Our fixed maturity investments are generally purchased in the context of various long-term strategies, including funding insurance liabilities, so we do not generally seek to generate short-term realized gains through the purchase and sale of such securities. In certain circumstances, including those in which securities are selling at prices which exceed our view of their underlying economic value, or when it is possible to reinvest the proceeds to better meet our long-term asset-liability objectives, we may sell certain securities. At June 30, 2024, there were no fixed maturity investments in default. During the first six months of 2024, the $33.5 million of gross realized losses on sales of $669.2 million of fixed maturity securities, available for sale, included: (i) $19.8 million related to various corporate securities; (ii) $9.2 million related to commercial mortgage-backed securities; and (iii) $4.5 million related to various other investments. Securities are generally sold at a loss following unforeseen issuer-specific events or conditions or shifts in perceived relative values. These reasons include but are not limited to: (i) changes in the investment environment; (ii) expectation that the market value could deteriorate; (iii) our desire to reduce our exposure (or reflect changing perceptions of risk) related to an asset class, an issuer or an industry; (iv) prospective or actual changes in credit quality; (v) better match certain characteristics of our investment portfolio with the corresponding characteristics of our insurance liabilities; (vi) changes in expected portfolio cash flows; or (vii) an opportunity to enhance the projected total return of the portfolio. During the first six months of 2023, the $36.0 million of gross realized losses on sales of $388.8 million of fixed maturity securities, available for sale, included: (i) $29.8 million related to various corporate securities; (ii) $4.3 million related to commercial mortgage-backed securities; and (iii) $1.9 million related to various other investments. Future events may occur, or additional information may become available, which may necessitate future realized losses in our portfolio. Significant losses could have a material adverse effect on our consolidated financial statements in future periods.

Insurance [Abstract]
LIABILITIES FOR INSURANCE PRODUCTS	LIABILITIES FOR INSURANCE PRODUCTS The liability for future policy benefits is determined based on numerous assumptions. The most significant assumptions for our life and annuity business are mortality and lapse/withdrawal rates which are based on our experience and, in cases of limited experience, industry experience. Mortality and lapse/withdrawal rates also take into consideration future expectations in policyholder behavior that may vary from past experience. For our health business, mortality rates, lapse rates, morbidity assumptions and future rate increases are based on our experience and, in cases of limited experience, industry experience. Such assumptions also consider future expectations in policyholder behavior that may vary from past experience. In the first six months of 2024, we reviewed the actual mortality, lapse, and morbidity experience and determined that no changes to assumptions for future cash flows were necessary. This is consistent with the impact in the "Effect of actual variances from expected experience" line items in the tables below, which indicate our actual experience did not deviate significantly from our expectations. The following tables summarize balances and changes in the liability for future policy benefits for traditional and limited-payment contracts for the six months ended June 30, 2024 (dollars in

comprised of blocks of business that are 100% ceded. (b) Such amount represents the difference between: (i) the total insurance liabilities for our fixed indexed annuities (including the host contract and the related embedded derivative); and (ii) the policyholder account balances for these products. The accounting requirement to bifurcate the embedded derivative and value it at the current estimated fair value results in this amount. (c) In certain instances for interest-sensitive products, the total insurance liabilities for a particular line of business may not be deficient in the aggregate to trigger loss recognition, but the pattern of earnings may be such that profits are expected to be recognized in earlier years followed by losses in later years. In these situations, accounting standards require that an additional liability (the "future loss reserve") be recognized by an amount necessary to sufficiently offset the losses that would be recognized in later years. Many of our fixed indexed annuity products include a guaranteed living withdrawal benefit ("GLWB") that is considered a market risk benefit ("MRB"). The calculation of MRBs includes market assumptions (interest rate, equity returns, volatility and dividend yields) and nonmarket assumptions (mortality rates, surrender and withdrawal rates, GLWB utilization and spreads). Market assumptions are updated quarterly to reflect current market conditions. During the first six months of 2024, we reviewed the nonmarket assumptions used to calculate MRBs and determined that such assumptions were appropriate. The following table presents the balance of and changes in MRBs associated with our fixed indexed annuities (dollars in millions): Six months ended June 30, 2024 2023 Net liability (asset), beginning of period $ (68.0) $ (54.0) Effect of changes in the instrument-specific credit risk, beginning of period 4.8 12.2 Balance, beginning of period, before effect of changes in the instrument-specific credit risk (63.2) (41.8) Issuances .1 (.1) Interest accrual 10.2 10.7 Attributed fees collected — — Benefit payments — — Effect of changes in interest rates (19.4) 4.2 Effect of changes in equity markets (3.8) 9.7 Effect of changes in equity index volatility (1.0) (25.3) Actual policyholder behavior different from expected behavior 4.1 1.8 Effect of changes in future expected policyholder behavior - other — — Effect of changes in future expected policyholder behavior - risk margin — — Effect of changes in assumptions (4.1) (3.9) Net liability (asset), end of period, before effect of changes in the instrument-specific credit risk (77.1) (44.7) Effect of changes in the instrument-specific credit risk, end of period (4.2) (10.8) Net liability (asset), end of period (81.3) (55.5) Reinsurance recoverable, end of period — — Net liability (asset), end of period, net of reinsurance $ (81.3) $ (55.5) Balance reported as an asset $ 84.5 $ 66.0 Balance reported as a liability 3.2 10.5 Net liability (asset) $ (81.3) $ (55.5) Net amount at risk $ 50.0 $ 52.0 Weighted average attained age of contract holders 69 69 The following table summarizes the amount of revenue and interest related to traditional and limited-payment contracts recognized in the consolidated statement of operations (dollars in millions): Gross premiums (a) Interest accretion (b) Six months ended Six months ended June 30, June 30, 2024 2023 2024 2023 Other annuities $ 2.6 $ 3.8 $ 7.0 $ 7.4 Supplemental health 361.1 355.0 83.8 83.8 Medicare supplement 309.0 307.2 5.2 5.4 Long-term care 170.0 163.6 87.6 86.7 Traditional life 362.0 357.3 57.2 56.1 Total $ 1,204.7 $ 1,186.9 $ 240.8 $ 239.4 _____________________ (a) Such amounts are included in insurance policy income in the consolidated statement of operations.

Segment Reporting [Abstract]
BUSINESS SEGMENTS	BUSINESS SEGMENTS We view our operations as three insurance product lines (annuity, health and life) and the investment and fee income segments. Our segments are aligned based on their common characteristics, comparability of profit margins and the way management makes operating decisions and assesses the performance of the business. Our insurance product line segments (annuity, health and life) include marketing, underwriting and administration of the policies our insurance subsidiaries sell. The business written in each of the three product categories through all of our insurance subsidiaries is aggregated allowing management and investors to assess the performance of each product category. When analyzing profitability of these segments, we use insurance product margin as the measure of profitability, which is: (i) insurance policy income; and (ii) net investment income allocated to the insurance product lines; less (i) insurance policy benefits and interest credited to policyholders; and (ii) amortization of deferred acquisition costs and present value of future profits, non-deferred commissions and advertising expense. Net investment income is allocated to the product lines using the book yield of investments backing the block of business, which is applied to the average net insurance liabilities for the block in each period. Net insurance liabilities for the purpose of allocating investment income to product lines are equal to: (i) policyholder account balances for annuity products; (ii) total reserves before the fair value adjustments reflected in accumulated other comprehensive income (loss), if applicable, for all other products; less (iii) amounts related to reinsured business; (iv) deferred acquisition costs; (v) the present value of future profits; and (vi) the value of unexpired options credited to insurance liabilities. Income from insurance products is the sum of the insurance product margins of the annuity, health and life product lines, less expenses allocated to the insurance lines. It excludes the income from our fee income business, investment income not allocated to product lines, net expenses not allocated to product lines (primarily holding company expenses) and income taxes. Management believes insurance product margin and income from insurance products help provide a better understanding of the business and a more meaningful analysis of the results of our insurance product lines. We market our products through the Consumer and Worksite Divisions that reflect the customers served by the Company. The Consumer and Worksite Divisions are primarily focused on marketing insurance products, several types of which are sold in both divisions and underwritten in the same manner. The Consumer Division serves individual consumers, engaging with them on the phone, virtually, online, face-to-face with agents, or through a combination of sales channels. This structure unifies consumer capabilities into a single division and integrates the strength of our agent sales forces with one of the largest direct-to-consumer insurance businesses with proven experience in advertising, web/digital and call center support. The Worksite Division focuses on the sale of voluntary benefit life and health insurance products in the workplace for businesses, associations, and other membership groups, interacting with customers at their place of employment and virtually. The Worksite Division also offers employer benefits services that seek to increase benefits engagement and reduce costs for employers and their employees. These services include: benefit administration technology, year-round advocacy, enrollment, benefits compliance and communications services. The investment segment involves the management of our capital resources, including investments and the management of corporate debt and liquidity. Our measure of profitability of this segment is the total net investment income not allocated to the insurance products. Investment income not allocated to product lines represents net investment income less: (i) equity returns credited to policyholder account balances; (ii) the investment income allocated to our product lines; (iii) interest expense on notes payable, investment borrowings and financing arrangements; (iv) expenses related to the FABN program; and (v) certain expenses related to benefit plans that are offset by special-purpose investment income; plus (vi) the impact of annual option forfeitures related to fixed indexed annuity surrenders. Investment income not allocated to product lines includes investment income on investments in excess of amounts allocated to product lines, investments held by our holding companies, the spread we earn from our Federal Home Loan Bank ("FHLB") investment borrowing and FABN programs and variable components of investment income (including call and prepayment income, adjustments to returns on structured securities due to cash flow changes, income (loss) from company-owned life insurance ("COLI") and alternative investment income not allocated to product lines), net of interest expense on corporate debt and financing arrangements. The spread earned from our FHLB investment borrowing and FABN programs includes the investment income on the matched assets less: (i) interest on investment borrowings related to the FHLB investment borrowing program; (ii) interest credited on funding agreements; and (iii) amortization of deferred acquisition costs related to the FABN program. Our fee income segment includes the earnings generated from sales of third-party insurance products, services provided by Optavise, LLC ("Optavise") and the operations of our broker/dealer and registered investment advisor. Expenses not allocated to product lines include the expenses of our corporate operations, excluding interest expense on debt. We measure segment performance by excluding total investment gains (losses), changes in fair value of embedded derivative liabilities and MRBs, fair value changes related to the agent deferred compensation plan, income taxes and other non-operating items consisting primarily of earnings attributable to VIEs ("pre-tax operating earnings") because we believe that this performance measure is a better indicator of the ongoing business and trends in our business. Our primary investment focus is on investment income to support our liabilities for insurance products as opposed to the generation of investment gains (losses), and a long-term focus is necessary to maintain profitability over the life of the business. Investment gains (losses), changes in fair value of embedded derivative liabilities and MRBs, fair value changes related to the agent deferred compensation plan and other non-operating items consisting primarily of earnings attributable to VIEs depend on market conditions or represent unusual items that do not necessarily relate to the underlying business of our segments. Investment gains (losses) and changes in fair value of embedded derivative liabilities and MRBs may affect future earnings levels since our underlying business is long-term in nature and changes in our investment portfolio may impact our ability to earn the assumed interest rates needed to maintain the profitability of our business.

We are generally able to change the participation rate at the beginning of each index period (typically on each policy anniversary date), subject to contractual minimums. The Company accounts for the options attributed to the policyholder for the estimated life of the contract as embedded derivatives. These accounting requirements often create volatility in the earnings from these products. We typically buy call options (including call spreads) referenced to the applicable indices in an effort to offset or hedge potential increases to policyholder benefits resulting from increases in the particular index to which the policy's return is linked. The notional amount of these options was $3.8 billion and $3.3 billion at June 30, 2024 and December 31, 2023, respectively. We are required to establish an embedded derivative related to a modified coinsurance agreement pursuant to which we assume the risks of a block of health insurance business. The embedded derivative represents the mark-to-market adjustment for approximately $78 million in underlying investments held by the ceding reinsurer at June 30, 2024. We purchase certain fixed maturity securities that contain embedded derivatives that are required to be held at fair value on the consolidated balance sheet. We have elected the fair value option to carry the entire security at fair value with changes in fair value recognized in net income.

We limit our exposure to such a loss by diversifying among several counterparties believed to be strong and creditworthy. At June 30, 2024, all of our counterparties were rated "A" or higher by S&P Global Ratings ("S&P"). The Company and its subsidiaries are parties to master netting arrangements with its counterparties related to entering into various derivative contracts.

We deduct this cost from insurance policy income. Reinsurance recoveries netted against insurance policy benefits totaled $89.8 million and $86.9 million in the second quarters of 2024 and 2023, respectively, and $195.6 million and $221.8 million in the first six months of 2024 and 2023, respectively. From time to time, we assume insurance from other companies. Any costs associated with the assumption of insurance are amortized consistent with the method used to amortize deferred acquisition costs. Reinsurance premiums assumed totaled $3.8 million and $4.3 million in the second quarters of 2024 and 2023, respectively, and $7.9 million and $8.4 million in the first six months of 2024 and 2023, respectively. Insurance policy benefits related to reinsurance assumed totaled $7.1 million and $5.8 million in the second quarters of 2024 and 2023, respectively, and $13.0 million and $10.5 million in the first six months of 2024 and 2023, respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company's interim tax expense is based upon the estimated annual effective tax rate for the respective period. Under authoritative guidance, certain items are required to be excluded from the estimated annual effective tax rate calculation. Such items include changes in judgment about the realizability of deferred tax assets resulting from changes in projections of income expected to be available in future years, and items deemed to be unusual, infrequent, or that cannot be reliably estimated. In these cases, the actual tax expense or benefit applicable to that item is treated discretely and is reported in the same period as the related item. The components of income tax expense (benefit) are as follows (dollars in millions): Three months ended Six months ended June 30, June 30, 2024 2023 2024 2023 Current tax expense $ 9.3 $ 19.7 $ 26.6 $ 33.7 Deferred tax expense (benefit) 25.0 2.7 41.6 (11.5) Total income tax expense $ 34.3 $ 22.4 $ 68.2 $ 22.2 A reconciliation of the U.S. statutory corporate tax rate to the estimated annual effective rate, reflected in the consolidated statement of operations is as follows: Six months ended June 30, 2024 2023 U.S. statutory corporate rate 21.0 % 21.0 % Non-taxable income and nondeductible benefits, net (.3) (.5) State taxes 2.3 2.8 Effective tax rate 23.0 % 23.3 % The components of the Company's income tax assets and liabilities are summarized below (dollars in millions): June 30, December 31, Deferred tax assets: Net federal operating loss carryforwards $ 255.4 $ 77.1 Net state operating loss carryforwards 41.1 2.5 Insurance liabilities 346.0 322.8 Indirect costs allocable to self-constructed real estate assets — 252.9 Accumulated other comprehensive loss 414.8 445.5 Other 20.2 35.6 Gross deferred tax assets 1,077.5 1,136.4 Deferred tax liabilities: Investments (38.7) (36.3) Present value of future profits and deferred acquisition costs (173.8) (163.0) Gross deferred tax liabilities (212.5) (199.3) Net deferred tax assets 865.0 937.1 Current income taxes prepaid (accrued) 17.8 (.9) Income tax assets, net $ 882.8 $ 936.2 Effective January 1, 2024, the Company elected to change its tax method of accounting for indirect costs allocable to self-constructed real estate assets. The change in accounting method would result in a current year tax deduction of certain indirect costs previously capitalized under the Company's prior method of accounting. Accordingly, for tax reporting purposes, the Company expects to recognize a tax loss of $985 million related to the change in accounting method which could be carried forward indefinitely pursuant to the Tax Cuts and Jobs Act, subject to limitations specified in the Internal Revenue Code (the “Code"). In the second quarter of 2024, the Internal Revenue Service (the "IRS") revised the list of tax method accounting changes that require approval from the IRS to include tax method accounting changes related to indirect costs allocable to self-constructed real estate assets. Previously, only a taxpayer-initiated election was necessary and IRS approval was not required. The Company requested approval for its tax method change in June 2024. If the Company’s request for a change in accounting method is ultimately not granted by the IRS, the remaining tax assets would be recharacterized as indirect costs allocable to self-constructed assets. Most of the assets associated with the indirect costs allocable to self-constructed real estate assets are currently held for sale or recently sold. Upon disposal of such assets, the related tax benefits would be reflected as net operating loss carryforwards ("NOLs") which could be carried forward indefinitely. With respect to the assets not currently held for sale, the tax benefits will be recognized over the 39 year depreciable life of the self-constructed assets or upon disposal. Our income tax expense includes deferred income taxes arising from temporary differences between the financial reporting and tax bases of assets and liabilities and NOLs. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which temporary differences are expected to be recovered or paid. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in earnings in the period when the changes are enacted. A reduction of the net carrying amount of deferred tax assets by establishing a valuation allowance is required if, based on the available evidence, it is more likely than not that such assets will not be realized. In assessing the need for a valuation allowance, all available evidence, both positive and negative, are considered to determine whether, based on the weight of that evidence, a valuation allowance for deferred tax assets is needed. This assessment requires significant judgment and considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of carryforward periods, our experience with operating loss and tax credit carryforwards expiring unused, and tax planning strategies. We evaluate the need to establish a valuation allowance for our deferred income tax assets on an ongoing basis using a deferred tax valuation model. Our model is adjusted to reflect changes in our projections of future taxable income. Our estimates of future taxable income are based on evidence we consider to be objectively verifiable. Such estimates are subject to numerous risks and uncertainties and the extent to which actual impacts differ from the assumptions used in our deferred tax valuation model. Based on our assessment, we have concluded that it is more likely than not that all our deferred tax assets of $865.0 million will be realized through future taxable earnings. Recovery of our deferred tax asset is dependent on achieving the level of future taxable income projected in our deferred tax valuation model and failure to do so could result in the recognition of a valuation allowance in a future period. The recognition of a valuation allowance would increase income tax expense and reduce shareholders' equity, and such an increase could have a significant impact upon our earnings in the future. The Code limits the extent to which losses realized by a non-life entity (or entities) may offset income from a life insurance company (or companies) to the lesser of: (i) 35 percent of the income of the life insurance company; or (ii) 35 percent of the total loss of the non-life entities (including NOLs of the non-life entities). There is no similar limitation on the extent to which losses realized by a life insurance entity (or entities) may offset income from a non-life entity (or entities). Section 382 of the Code imposes limitations on a corporation's ability to use its NOLs when the company undergoes a 50 percent ownership change over a three-year period. Future transactions and the timing of such transactions could cause an ownership change for Section 382 income tax purposes. Such transactions may include, but are not limited to, additional repurchases under our securities repurchase program, issuances of common stock and acquisitions or sales of shares of CNO stock by certain holders of our shares, including persons who have held, currently hold or may accumulate in the future five percent or more of our outstanding common stock for their own account. Many of these transactions are beyond our control. If an additional ownership change were to occur for purposes of Section 382, we would be required to calculate an annual restriction on the use of our NOLs to offset future taxable income. The annual restriction would be calculated based upon the value of CNO's equity at the time of such ownership change, multiplied by a federal long-term tax exempt rate (3.62 percent at June 30, 2024), and the annual restriction could limit our ability to use a substantial portion of our NOLs to offset future taxable income or may defer the utilization of such NOLs. We regularly monitor ownership change (as calculated for purposes of Section 382) and, as of June 30, 2024, we were below the 50 percent ownership change level that could limit our ability to utilize our NOLs. We have $1.2 billion of federal non-life NOLs as of June 30, 2024, as summarized below (dollars in millions): Net operating loss Year of expiration carryforwards 2026 $ 15.8 2027 10.8 2028 through 2035 340.7 No expiration date (a) 849.0 Total federal non-life NOLs $ 1,216.3 ____________________ (a) Pending IRS approval of our tax method change or disposal of self-constructed assets. Our non-life NOLs with expiration dates can be used to offset 35 percent of life insurance company taxable income and 100 percent of non-life company taxable income until all non-life NOLs are utilized or expire. Our non-life NOLs with no expiration date can be used to offset 35 percent of life insurance company taxable income and 80 percent of non-life company taxable income. We also had deferred tax assets related to NOLs for state income taxes of $41.1 million and $2.5 million at June 30, 2024 and December 31, 2023, respectively. The related state NOLs are available to offset future state taxable income in certain states and are expected to be fully utilized prior to expiration. The IRS is conducting an examination of our 2016 through 2018 tax returns. The federal statute of limitations remains open with respect to tax years 2016 through 2023. The Company's various state income tax returns are generally open for tax years based on individual state statutes of limitation. Generally, for tax years which generate NOLs, capital losses or tax credit carryforwards, the statute remains open until the expiration of the statute of limitations for the tax year in which such carryforwards are utilized. The outcome of tax audits cannot be predicted with certainty. If the Company's tax audits are not

The 2034 Notes were issued under the Indenture, dated as of June 12, 2019 (the "Base Indenture") as supplemented by the Third Supplemental Indenture, dated as of May 13, 2024 (the "Supplemental Indenture" and, together with the Base Indenture, the "Indenture"), each between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the "Trustee"). The 2034 Notes mature on June 15, 2034, unless earlier repurchased by the Company, and interest on the 2034 Notes is payable at 6.450% per annum. Interest on the 2034 Notes is paid semi-annually on June 15 and December 15 of each year, beginning on December 15, 2024. The 2034 Notes are senior unsecured obligations and rank equally with the Company’s other senior unsecured and unsubordinated debt from time to time outstanding, including obligations under our Revolving Credit Agreement (as defined below). The 2034 Notes are effectively subordinated to all of the Company’s future indebtedness that is secured, to the extent of the value of the assets securing such indebtedness. The 2034 Notes are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s subsidiaries. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or the holders of not less than 25% in aggregate principal amount of the 2034 Notes then outstanding may declare the entire principal amount of all the 2034 Notes, and the interest accrued on such 2034 Notes, if any, to be immediately due and payable. In the case of certain events of bankruptcy, insolvency or reorganization relating to the Company, the principal amount of the securities together with any accrued and unpaid interest thereon will automatically be and become immediately due and payable. Prior to March 15, 2034 (the date that is three months prior to the maturity date of the 2034 Notes) (the "Par Call Date"), the 2034 Notes are redeemable at a redemption price equal to the greater of (i) 100% of the principal amount of the 2034 Notes to be redeemed, or (ii)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the 2034 Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Indenture) plus 30 basis points less (b) interest accrued to the date of redemption, plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date. On and after the Par Call Date, the 2034 Notes are redeemable at a redemption price equal to 100% of the principal amount of the 2034 Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. The Company expects to use the net proceeds from the offering of the 2034 Notes (the “Offering”), together with cash on hand: (i) for general corporate purposes, which includes the repayment of its $500.0 million of 5.250% Senior Notes due May 2025 (the "2025 Notes"); and (ii) to pay fees, costs and expenses in connection with the foregoing and the Offering. The following table sets forth the sources and uses of cash from the transaction (dollars in millions): Sources: 2034 Notes, net of original issue discount $ 697.7 Uses: General corporate purposes (including 500.0 million invested primarily in certificates of deposit for the repayment at maturity of the 2025 Notes) $ 691.0 Debt issuance costs 6.7 $ 697.7 Revolving Credit Agreement The $250.0 million revolving credit agreement (the "Revolving Credit Agreement"), among other things, (i) requires the Company to maintain (each as calculated in accordance with the Revolving Credit Agreement): (i) a debt to total capitalization ratio (excluding hybrid securities, except to the extent that the aggregate amount outstanding of all such hybrid securities exceeds an amount equal to 15 percent of total capitalization) of not more than 35.0 percent (such ratio was 30.5 percent at June 30, 2024); and (ii) a minimum consolidated net worth of not less than the sum of (x) $2,674 million plus (y) 25.0 percent of the net equity proceeds received by the Company from the issuance and sale of equity interests in the Company (the Company's consolidated net worth was $3,893.2 million at June 30, 2024 compared to the minimum requirement of $2,697.5 million). The maturity date of the Revolving Credit Agreement is July 16, 2026. The Revolving Credit Agreement contains certain other restrictive covenants with which the Company must comply. The interest rate applicable to loans under the Revolving Credit Agreement is calculated as the Secured Overnight Financing Rate ("SOFR") (plus a credit spread adjustment of 0.10 percent for all available interest periods) or the base rate (as defined in the Revolving Credit Agreement), at the Company's option, plus a margin based on the Company's unsecured debt rating. The margins under the Revolving Credit Agreement range from 1.375 percent to 2.125 percent, in the case of loans at the SOFR, and 0.375 percent to 1.125 percent, in the case of loans at the base rate. The commitment fee under the Revolving Credit Agreement is based on the Company's unsecured debt rating. There were no amounts outstanding under the Revolving Credit Agreement during the six months ended June 30, 2024.

We are required to hold certain minimum amounts of FHLB common stock as a condition of membership in the FHLB, and additional amounts based on the amount of the borrowings. At June 30, 2024, the carrying value of the FHLB common stock was $94.6 million. As of June 30, 2024, collateralized borrowings from the FHLB totaled $2.2 billion and the proceeds were used to purchase variable rate fixed maturity securities with similar durations. The borrowings are classified as investment borrowings in the accompanying consolidated balance sheet. The borrowings are collateralized by investments with an estimated fair value of $2.9 billion at June 30, 2024, which are maintained in a custodial account for the benefit of the FHLB. Substantially all of such investments are classified as fixed maturities, available for sale, in our consolidated balance sheet. The following summarizes the terms of the borrowings from the FHLB by our insurance subsidiaries (dollars in millions): Amount Maturity Interest rate at borrowed date June 30, 2024 $ 15.5 July 2024 Fixed rate – 1.990% 27.0 August 2024 Fixed rate – .640% 21.7 May 2025 Variable rate – 5.695% 17.8 June 2025 Fixed rate – 2.940% 12.5 June 2025 Variable rate – 5.910% 125.0 September 2025 Variable rate – 5.690% 100.0 October 2025 Variable rate – 5.834% 100.0 October 2025 Variable rate – 5.824% 57.7 October 2025 Variable rate – 5.801% 50.0 November 2025 Variable rate – 5.834% 12.5 December 2025 Variable rate – 5.926% 50.0 January 2026 Variable rate – 5.819% 50.0 January 2026 Variable rate – 5.824% 100.0 January 2026 Variable rate – 5.794% 5.0 May 2026 Variable rate – 5.766% 21.8 May 2026 Variable rate – 5.684% 50.0 May 2026 Variable rate – 5.610% 10.0 November 2026 Variable rate – 5.814% 75.0 December 2026 Variable rate – 5.752% 75.0 January 2027 Variable rate – 5.667% 50.0 January 2027 Variable rate – 5.763% 50.0 January 2027 Variable rate – 5.759% 100.0 January 2027 Variable rate – 5.792% 100.0 February 2027 Variable rate – 5.734% 50.0 April 2027 Variable rate – 5.630% 50.0 May 2027 Variable rate – 5.640% 100.0 June 2027 Variable rate – 5.710% 10.0 June 2027 Variable rate – 5.933% 50.0 July 2027 Variable rate – 6.000% 50.0 July 2027 Variable rate – 6.044% 100.0 August 2027 Variable rate – 6.015% 75.0 January 2028 Variable rate – 5.755% 50.0 January 2028 Variable rate – 5.803% 50.0 January 2028 Variable rate – 5.824% 34.5 February 2028 Variable rate – 5.875% 100.0 February 2028 Variable rate – 5.824% 21.0 February 2028 Variable rate – 5.744% 22.0 February 2028 Variable rate – 5.830% 100.0 February 2028 Variable rate – 5.754% 15.0 July 2028 Variable rate – 5.720% 35.0 August 2028 Variable rate – 5.730% $ 2,189.0 Generally, the variable and fixed rate borrowings are pre-payable. At June 30, 2024, the aggregate prepayment penalty on such outstanding borrowings was not material. Interest expense of $62.8 million and $45.9 million in the first six months of 2024 and 2023, respectively, was recognized related to total borrowings from the FHLB, reflecting both higher interest rates on the variable rate investment borrowings and higher average borrowings outstanding in the 2024 period.

Commitments and Contingencies Disclosure [Abstract]
LITIGATION AND OTHER LEGAL PROCEEDINGS	LITIGATION AND OTHER LEGAL PROCEEDINGS Legal Proceedings The Company and its subsidiaries are involved in various legal actions in the normal course of business, in which claims for compensatory and punitive damages are asserted, some for substantial amounts. We recognize an estimated loss from these loss contingencies when we believe it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Some of the pending matters have been filed as purported class actions and some actions have been filed in certain jurisdictions that permit punitive damage awards that are disproportionate to the actual damages incurred. The amounts sought in certain of these actions are often large or indeterminate and the ultimate outcome of certain actions is difficult to predict. In the event of an adverse outcome in one or more of these matters, there is a possibility that the ultimate liability may be in excess of the liabilities we have established and could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, the resolution of pending or future litigation may involve modifications to the terms of outstanding insurance policies or could impact the timing and amount of rate increases, which could adversely affect the future profitability of the related insurance policies. Based upon information presently available, and in light of legal, factual and other defenses available to the Company and its subsidiaries, the Company does not believe that it is probable that the ultimate liability from either pending or threatened legal actions, after consideration of existing loss provisions, will have a material adverse effect on the Company's consolidated financial condition, operating results or cash flows. However, given the inherent difficulty in predicting the outcome of legal proceedings, there exists the possibility that such legal actions could have a material adverse effect on the Company's consolidated financial condition, operating results or cash flows. In addition to the inherent difficulty of predicting litigation outcomes, particularly those that will be decided by a jury, some matters purport to seek substantial or an unspecified amount of damages for unsubstantiated conduct spanning several years based on complex legal theories and damages models. The alleged damages typically are indeterminate or not factually supported in the complaint, and, in any event, the Company's experience indicates that monetary demands for damages often bear little relation to the ultimate loss. In some cases, plaintiffs are seeking to certify classes in the litigation and class certification either has been denied or is pending and we have filed oppositions to class certification or sought to decertify a prior class certification. In addition, for many of these cases: (i) there is uncertainty as to the outcome of pending appeals or motions; (ii) there are significant factual issues to be resolved; and/or (iii) there are novel legal issues presented. Accordingly, the Company cannot reasonably estimate the possible loss or range of loss in excess of amounts accrued, if any, or predict the timing of the eventual resolution of these matters. The Company reviews these matters on an ongoing basis. When assessing reasonably possible and probable outcomes, the Company bases its assessment on the expected ultimate outcome following all appeals. On June 7, 2019, Platinum Partners Value Arbitrage Fund L.P. (in Official Liquidation) ("PPVA"), the Joint Official Liquidators of PPVA (the "JOLs") and Principal Growth Strategies, LLC, ("PGS"), commenced suit against, among others, CNO Financial Group, Inc., Bankers Conseco Life Insurance Company ("BCLIC"), Washington National and 40|86 Advisors, Inc. (collectively, the "CNO Parties") in Delaware Chancery Court. Plaintiffs seek an unspecified amount of damages, costs, attorney's fees, and other relief as the court deems appropriate. Plaintiffs allege that the CNO Parties were unjustly enriched when they terminated BCLIC and Washington National's reinsurance agreements with BRe and recaptured assets from reinsurance trusts, in particular, Agera securities. Plaintiffs contend that the Agera securities were fraudulently transferred to the reinsurance trusts by other Platinum-related entities and they are seeking to claw back those Agera securities, or the value of those assets, from the CNO Parties. The CNO Parties had removed the case to the United States District Court for the District of Delaware but on April 6, 2020, the District Court granted the plaintiff's motion to remand the case back to the Delaware Chancery Court. Plaintiffs have filed an Amended Complaint and the CNO Parties have moved to dismiss the Amended Complaint. The Delaware Chancery Court denied the CNO Parties’ motions to dismiss the Amended Complaint on the basis of forum non conveniens, but granted the CNO Parties’ motion to stay the case pending the conclusion of a related matter. On December 1, 2023, the Delaware Chancery Court lifted the stay as of November 30, 2023. On January 25, 2024, the Delaware Chancery Court granted in part and denied in part the CNO Parties’ motion to dismiss the Amended Complaint. Based on the Court’s ruling, PPVA and the JOLs’ claims against the CNO Parties were dismissed. On April 9, 2024, PGS filed a second amended complaint, which contains the same claims against the CNO Parties that PGS had previously asserted. The CNO Parties are vigorously contesting PGS's claims. On October 5, 2012, plaintiffs William Jeffrey Burnett and Joe H. Camp commenced an action entitled Burnett v. Conseco Life Ins. Co. against, among others, CNO Financial Group, Inc. and CNO Services, LLC (collectively, the "CNO Entities") in the United States District Court for the Central District of California on behalf of a putative class of former interest-sensitive whole life insurance policyholders who surrendered their policies or let them lapse. Plaintiffs' first amended complaint alleges that the CNO Entities are liable under an alter ego theory for Conseco Life Insurance Company's purported breach of the optional premium payment provision (the "Optional Premium Payment") of plaintiffs' insurance policies. In January 2018, the case was transferred to the United States District Court for the Southern District of Indiana. On August 17, 2020, the Court denied the CNO Entities' motions to dismiss. On January 13, 2021, the Court granted final approval of a class action settlement between plaintiffs and co-defendant Conseco Life Insurance Company (n/k/a Wilco Life Insurance Company). The case remains pending against the CNO Entities. On March 25, 2022, the Court certified a Rule 23(b)(3) class of under 2,000 policyholders who invoked the policy's Optional Premium Payment prior to October 2008 and who surrendered their policies between October 7, 2008 and September 1, 2011. The Court's certification order acknowledged the existence of individualized issues of causation and damages, which the Court stated could be addressed in individualized proceedings following a class trial on the alter ego allegations and the meaning of the subject insurance policy language. The CNO Entities continue to vigorously defend the case. Regulatory Examinations and Fines Insurance companies face significant risks related to regulatory investigations and actions. Regulatory investigations generally result from matters related to sales or underwriting practices, payment of contingent or other sales commissions, claim payments and procedures, product design, product disclosure, additional premium charges for premiums paid on a periodic basis, denial or delay of benefits, charging excessive or impermissible fees on products, procedures related to canceling policies, changing the way cost of insurance charges are calculated for certain life insurance products or recommending unsuitable products to customers. We are, in the ordinary course of our business, subject to various examinations, inquiries and information requests from state, federal and other authorities. The ultimate outcome of these regulatory actions (including the costs of complying with information requests and policy reviews) cannot be predicted with certainty. In the event of an unfavorable outcome in one or more of these matters, the ultimate liability may be in excess of liabilities we have established and we could suffer significant reputational harm as a result of these matters, which could also have a material adverse effect on our business, financial condition, results of operations or cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
INVESTMENTS IN VARIABLE INTEREST ENTITIES	INVESTMENTS IN VARIABLE INTEREST ENTITIES We have concluded that we are the primary beneficiary with respect to certain VIEs, which are consolidated in our financial statements. In consolidating the VIEs, we consistently use the financial information most recently distributed to investors in the VIE. All of the VIEs are collateralized loan trusts that were established to issue securities to finance the purchase of corporate loans and other permitted investments. The assets held by the trusts are legally isolated and not available to the Company. The liabilities of the VIEs are expected to be satisfied from the cash flows generated by the underlying loans held by the trusts, not from the assets of the Company. The Company has no financial obligation to the VIEs beyond its investment in each VIE. Certain of our subsidiaries are noteholders of the VIEs. Another subsidiary of the Company is the investment manager for the VIEs. As such, it has the power to direct the most significant activities of the VIEs which materially impacts the economic performance of the VIEs. The following tables provide supplemental information about the assets and liabilities of the VIEs which have been consolidated in accordance with authoritative guidance (dollars in millions): June 30, 2024 VIEs Eliminations Net effect on Assets: Investments held by variable interest entities $ 425.5 $ — $ 425.5 Notes receivable of VIEs held by subsidiaries — (104.9) (104.9) Cash and cash equivalents held by variable interest entities 113.3 — 113.3 Accrued investment income 1.5 — 1.5 Income tax assets, net 13.7 — 13.7 Other assets 8.4 (.5) 7.9 Total assets $ 562.4 $ (105.4) $ 457.0 Liabilities: Other liabilities $ 9.6 $ (2.2) $ 7.4 Borrowings related to variable interest entities 501.4 — 501.4 Notes payable of VIEs held by subsidiaries 106.1 (106.1) — Total liabilities $ 617.1 $ (108.3) $ 508.8 December 31, 2023 VIEs Eliminations Net effect on Assets: Investments held by variable interest entities $ 768.6 $ — $ 768.6 Notes receivable of VIEs held by subsidiaries — (113.8) (113.8) Cash and cash equivalents held by variable interest entities 114.5 — 114.5 Accrued investment income 2.7 — 2.7 Income tax assets, net 13.0 — 13.0 Other assets — (.7) (.7) Total assets $ 898.8 $ (114.5) $ 784.3 Liabilities: Other liabilities $ 14.6 $ (2.2) $ 12.4 Borrowings related to variable interest entities 820.8 — 820.8 Notes payable of VIEs held by subsidiaries 126.1 (126.1) — Total liabilities $ 961.5 $ (128.3) $ 833.2 The investment portfolios held by the VIEs are primarily comprised of commercial bank loans to corporate obligors which are almost entirely rated below-investment grade. At June 30, 2024, such loans had an amortized cost of $440.6 million; gross unrealized gains of $1.3 million; gross unrealized losses of $13.6 million; allowance for credit losses of $2.8 million; and an estimated fair value of $425.5 million. The following table summarizes changes in the allowance for credit losses related to corporate securities held by VIEs for the three months ended June 30, 2024 and 2023 (dollars in millions): Three months ended June 30, 2024 2023 Allowance at the beginning of the period $ 4.3 $ 3.5 Additions for securities for which credit losses were not previously recorded — .4 Additions (reductions) for securities where an allowance was previously recorded .2 .8 Reduction for securities sold during the period (1.7) (.2) Allowance at the end of the period $ 2.8 $ 4.5 The following table summarizes changes in the allowance for credit losses related to corporate securities held by VIEs for the six months ended June 30, 2024 and 2023 (dollars in millions): Six months ended June 30, 2024 2023 Allowance at the beginning of the period $ 3.1 $ 5.5 Additions for securities for which credit losses were not previously recorded .3 .7 Additions (reductions) for securities where an allowance was previously recorded 1.9 .1 Reduction for securities sold during the period (2.5) (1.8) Allowance at the end of the period $ 2.8 $ 4.5 The following table sets forth the amortized cost and estimated fair value of the investments held by the VIEs at June 30, 2024, by contractual maturity. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without penalties. Amortized Estimated (Dollars in millions) Due in one year or less $ 13.2 $ 11.3 Due after one year through five years 413.2 399.9 Due after five years through ten years 14.2 14.3 Total $ 440.6 $ 425.5 During the first six months of 2024, the VIEs recognized investment losses of $5.7 million which were comprised of: (i) $9.8 million of net losses from the sales of fixed maturities; (ii) $3.8 million of gains related to the liquidation of a VIE; and (iii) a decrease in the allowance for credit losses of $0.3 million. Such net realized losses included gross realized losses of $10.6 million from the sale of $103.1 million of investments. During the first six months of 2023, the VIEs recognized net investment losses of $4.0 million which were comprised of: (i) $5.0 million of net losses from the sales of fixed maturities; and (ii) a decrease in the allowance for credit losses of $1.0 million. Such net realized losses included gross realized losses of $5.2 million from the sale of $11.0 million of investments. At June 30, 2024, there were no fixed maturity investments held by the VIEs in default. At June 30, 2024, the VIEs held: (i) investments (for which an allowance for credit losses has not been recorded) with a fair value of $56.6 million and gross unrealized losses not deemed to have credit losses of $0.3 million that had been in an unrealized loss position for less than twelve months; and (ii) investments (for which an allowance for credit losses has not been recorded) with a fair value of $89.6 million and gross unrealized losses not deemed to have credit losses of $2.2 million that had been in an unrealized loss position for twelve months or greater. At December 31, 2023, the VIEs held: (i) investments (for which an allowance for credit losses has not been recorded) with a fair value of $24.8 million and gross unrealized losses of $0.1 million that had been in an unrealized loss position for less than twelve months; and (ii) investments (for which an allowance for credit losses has not been recorded) with a fair value of $302.3 million and gross unrealized losses of $8.7 million that had been in an unrealized loss position for twelve months or greater. The investments held by the VIEs are evaluated for impairment in a manner that is consistent with the Company's fixed maturities, available for sale. In addition, the Company, in the normal course of business, makes passive investments in structured securities issued by VIEs for which the Company is not the investment manager. These structured securities include asset-backed securities, collateralized loan obligations, commercial mortgage-backed securities, agency residential mortgage-backed securities and non-agency residential mortgage-backed securities. Our maximum exposure to loss on these securities is limited to our cost basis in the investment. We have determined that we are not the primary beneficiary of these structured securities due to the relative size of our investment in comparison to the total principal amount of the individual structured securities and the level of credit subordination which reduces our obligation to absorb gains or losses. At June 30, 2024, we held investments in various limited partnerships and hedge funds, in which we are not the primary beneficiary, totaling $477.8 million (classified as other invested assets). At June 30, 2024, we had unfunded commitments to these partnerships totaling $398.1 million. Our maximum exposure to loss on these investments is limited to the amount of our investment.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, therefore, represents an exit price, not an entry price. We carry certain assets and liabilities at fair value on a recurring basis, including fixed maturities, equity securities, trading securities, investments held by VIEs, derivatives, separate account assets and embedded derivatives. We carry our COLI, which is invested in a series of mutual funds, at its cash surrender value which approximates fair value. In addition, we disclose fair value for certain financial instruments that are not carried at fair value, including mortgage loans, policy loans, cash and cash equivalents, insurance liabilities for interest-sensitive products and funding agreements, investment borrowings, notes payable and borrowings related to VIEs. The degree of judgment utilized in measuring the fair value of financial instruments is largely dependent on the level to which pricing is based on observable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our view of market assumptions in the absence of observable market information. Financial instruments with readily available active quoted prices would be considered to have fair values based on the highest level of observable inputs, and little judgment would be utilized in measuring fair value. Financial instruments that rarely trade would often have fair value based on a lower level of observable inputs, and more judgment would be utilized in measuring fair value. Valuation Hierarchy There is a three-level hierarchy for valuing assets or liabilities at fair value based on whether inputs are observable or unobservable. • Level 1 – includes assets and liabilities valued using inputs that are unadjusted quoted prices in active markets for identical assets or liabilities. Our Level 1 assets primarily include cash and cash equivalents and exchange-traded securities. • Level 2 – includes assets and liabilities valued using inputs that are quoted prices for similar assets in an active market, quoted prices for identical or similar assets in a market that is not active, observable inputs, or observable inputs that can be corroborated by market data. Level 2 assets and liabilities include those financial instruments that are valued by independent pricing services using models or other valuation methodologies. These models consider various inputs such as credit rating, maturity, corporate credit spreads, reported trades and other inputs that are observable or derived from observable information in the marketplace or are supported by transactions executed in the marketplace. Financial assets in this category primarily include: certain publicly registered and privately placed corporate fixed maturity securities; certain government or agency securities; certain mortgage and asset-backed securities; certain equity securities; most investments held by our consolidated VIEs; and derivatives such as call options. Financial liabilities in this category include investment borrowings, notes payable and borrowings related to VIEs. • Level 3 – includes assets and liabilities valued using unobservable inputs that are used in model-based valuations that contain management assumptions. Level 3 assets and liabilities include those financial instruments whose fair value is estimated based on broker/dealer quotes, pricing services or internally developed models or methodologies utilizing significant inputs not based on, or corroborated by, readily available market information. Financial assets in this category include certain corporate securities, certain structured securities, mortgage loans, and other less liquid securities. Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives (including embedded derivatives related to our fixed indexed annuity products and to a modified coinsurance arrangement), and funding agreements since their values include significant unobservable inputs including actuarial assumptions. At each reporting date, we classify assets and liabilities into the three input levels based on the lowest level of input that is significant to the measurement of fair value for each asset and liability reported at fair value. This classification is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction and overall market conditions. Our assessment of the significance of a particular input to the fair value measurement and the ultimate classification of each asset and liability requires judgment and is subject to change from period to period based on the observability of the valuation inputs. The vast majority of our assets carried at fair value use Level 2 inputs for the determination of fair value. These fair values are obtained primarily from independent pricing services, which use Level 2 inputs for the determination of fair value. Our Level 2 assets are valued as follows: • Fixed maturities available for sale, equity securities and trading securities Corporate securities are generally priced using market and income approaches using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads. U.S. Treasuries and obligations of U.S. Government corporations and agencies are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets and maturity. States and political subdivisions are generally priced using the market approach using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, new issuances and credit spreads. Foreign governments are generally priced using the market approach using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, new issuances, benchmark yields, credit spreads and issuer rating. Asset-backed securities, agency and non-agency residential mortgage-backed securities, collateralized loan obligations and commercial mortgage-backed securities are generally priced using market and income approaches using independent pricing services. Inputs generally consist of quoted prices in inactive markets, spreads on actively traded securities, expected prepayments, expected default rates, expected recovery rates and issue specific information including, but not limited to, collateral type, seniority and vintage. Equity securities are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads. • Investments held by VIEs Corporate securities are generally priced using market and income approaches using pricing vendors. Inputs generally consist of issuer rating, benchmark yields, maturity, and credit spreads. • Other invested assets - derivatives The fair value measurements for derivative instruments, including embedded derivatives requiring bifurcation, are determined based on the consideration of several inputs including closing exchange or over-the-counter market price quotes, time value and volatility factors underlying options, market interest rates and non-performance risk. Third-party pricing services normally derive security prices through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. If there are no recently reported trades, the third-party pricing services may use matrix or model processes to develop a security price where future cash flow expectations are discounted at an estimated risk-adjusted market rate. The number of prices obtained for a given security is dependent on the Company's analysis of such prices as further described below. As the Company is responsible for the determination of fair value, we have control processes designed to ensure that the fair values received from third-party pricing sources are reasonable and the valuation techniques and assumptions used appear reasonable and consistent with prevailing market conditions. Additionally, when inputs are provided by third-party pricing sources, we have controls in place to review those inputs for reasonableness. As part of these controls, we perform monthly quantitative and qualitative analysis on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. The Company's analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) where available, a comparison of multiple pricing services' valuations for the same security; (iii) a review of month to month price fluctuations; (iv) a review to ensure valuations are not unreasonably dated; and (v) back testing to compare actual purchase and sale transactions with valuations received from third parties. As a result of such procedures, the Company may conclude a particular price received from a third-party is not reflective of current market conditions. In those instances, we may request additional pricing quotes or apply internally developed valuations. However, the number of such instances is insignificant and the aggregate change in value of such investments is not materially different from the original prices received. The categorization of the fair value measurements of our investments priced by independent pricing services was based upon the Company's judgment of the inputs or methodologies used by the independent pricing services to value different asset classes. Such inputs typically include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers and other relevant data. The Company categorizes such fair value measurements based upon asset classes and the underlying observable or unobservable inputs used to value such investments. For securities that are not priced by pricing services and may not be reliably priced using pricing models, we obtain broker quotes. These broker quotes are non-binding and represent an exit price, but assumptions used to establish the fair value may not be observable and therefore represent Level 3 inputs. Approximately 92 percent of our Level 3 fixed maturity securities and trading securities were valued using unadjusted broker quotes or broker-provided valuation inputs. The remaining Level 3 fixed maturity investments do not have readily determinable market prices and/or observable inputs. For these securities, we use internally developed valuations. Key assumptions used to determine fair value for these securities may include risk premiums, projected performance of underlying collateral and other factors involving significant assumptions which may not be reflective of an active market. For certain investments, we use a matrix or model process to develop a security price where future cash flow expectations are discounted at an estimated market rate. The pricing matrix incorporates term interest rates as well as a spread level based on the issuer's credit rating, other factors relating to the issuer, and the security's maturity. In some instances issuer-specific spread adjustments, which can be positive or negative, are made based upon internal analysis of security specifics such as liquidity, deal size, and time to maturity. The categorization of fair value measurements, by input level, for our financial instruments carried at fair value on a recurring basis at June 30, 2024 is as follows (dollars in millions): Quoted prices in active markets Significant other observable inputs Significant unobservable inputs Total Assets: Fixed maturities, available for sale: Corporate securities $ — $ 11,660.4 $ 127.7 $ 11,788.1 Certificates of deposit — 473.7 — 473.7 United States Treasury securities and obligations of United States government corporations and agencies — 256.5 — 256.5 States and political subdivisions — 2,810.8 — 2,810.8 Foreign governments — 87.7 — 87.7 Asset-backed securities — 1,442.9 25.8 1,468.7 Agency residential mortgage-backed securities — 789.4 — 789.4 Non-agency residential mortgage-backed securities — 1,552.8 — 1,552.8 Collateralized loan obligations — 1,224.9 — 1,224.9 Commercial mortgage-backed securities — 2,165.3 — 2,165.3 Total fixed maturities, available for sale — 22,464.4 153.5 22,617.9 Equity securities -

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	When we prepare financial statements in conformity with GAAP, we are required to make estimates and assumptions that significantly affect reported amounts of various assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting periods. For example, we use significant estimates and assumptions to calculate values for deferred acquisition costs, the present value of future profits, fair value measurements of certain investments (including derivatives), allowance for credit losses and other-than-temporary impairments of investments, assets and liabilities related to income taxes, liabilities for insurance products, liabilities related to litigation and guaranty fund assessment accruals. If our future experience differs from these estimates and assumptions, our financial statements could be materially affected.
Consolidation	The accompanying financial statements are unaudited and include the accounts of the Company and its subsidiaries. Our consolidated financial statements exclude transactions between us and our consolidated affiliates, or among our consolidated affiliates.
Recently Issued Accounting Standards	In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. Such requirements include: (i) disclosures on significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss on an annual and interim basis; (ii) disclosures of an amount for other segment items by reportable segment and a description of its composition on an annual and interim basis (the other segment items category is the difference between segment revenues less the segment expenses disclosed pursuant to the new guidance); (iii) providing all annual disclosures on a reportable segment’s profit or loss and assets currently required by FASB ASC Topic 280, Segment Reporting in interim periods; and (iv) specifying the title and position of the CODM and an explanation of how the CODM uses the reported measures to assess segment performance and make decisions about allocating resources. ASU 2023-07 is effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, to be applied on a retrospective basis (with early adoption permitted). The adoption of ASU 2023-07 will expand our disclosures but will not have an impact on our financial position or results of operations. In December 2023, the FASB issued Accounting Standards Update 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 is intended to improve the effectiveness of income tax disclosures by requiring, among other things, the disclosure on an annual basis of: (i) specific categories in the rate reconciliation; and (ii) additional information for reconciling items that meet a quantitative threshold. In addition, ASU 2023-09 requires disclosure (on an annual basis) of the following information about income taxes paid: (i) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; and (ii) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). ASU 2023-09 is effective for annual periods beginning January 1, 2025, to be applied prospectively with an option for retrospective application (with early adoption permitted). The adoption of ASU 2023-09 will modify our disclosures but will not have an impact on our financial position or results of operations.
Investments	We classify our fixed maturity securities into one of two categories: (i) "available for sale" (which we carry at estimated fair value with any unrealized gain or loss, net of any allowance for credit losses and income taxes, recorded as a component of shareholders' equity); or (ii) "trading" (which we carry at estimated fair value with changes in such value recognized as either net investment income (classified as investment income from policyholder and other special-purpose portfolios) or investment gains (losses)). Trading securities include: (i) investments purchased with the intent of selling in the near term to generate income; and (ii) certain fixed maturity securities containing embedded derivatives for which we have elected the fair value option. The change in fair value of the income generating investments is recognized in income from policyholder and other special-purpose portfolios (a component of net investment income). The change in fair value of securities with embedded derivatives is recognized in other investment gains (losses). We review our available for sale fixed maturity securities with unrealized losses to determine whether such impairments are the result of credit losses. We analyze various factors to make such determinations including, but not limited to: (i) actions taken by rating agencies; (ii) default by the issuer; (iii) the significance of the decline; (iv) an assessment of our intent to sell the security before recovering the security's amortized cost; (v) an economic analysis of the issuer's industry; and (vi) the financial strength, liquidity, and recoverability of the issuer. We perform a security by security review each quarter to evaluate whether a credit loss has occurred. In determining the credit loss component, we discount the estimated cash flows on a security by security basis. We consider the impact of macroeconomic conditions on inputs used to measure the amount of credit loss. For most structured securities, cash flow estimates are based on bond-specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity, prepayment speeds and structural support, including overcollateralization, excess spread, subordination and guarantees. For corporate bonds, cash flow estimates are derived by considering asset type, rating, time to maturity, and applying an expected loss rate. If a portion of the decline is due to credit-related factors, we separate the credit loss component of the impairment from the amount related to all other factors. The credit loss component is recorded as an allowance and reported in other investment gains (losses) (limited to the difference between estimated fair value and amortized cost). The impairment related to all other factors (non-credit factors) is reported in accumulated other comprehensive income (loss) along with unrealized gains (losses) related to fixed maturity investments, available for sale, net of tax and related adjustments. The allowance is adjusted for any additional credit losses and subsequent recoveries. When recognizing an allowance associated with a credit loss, the cost basis is not adjusted. When we determine a security is uncollectable, the remaining amortized cost will be written off. If we intend to sell an impaired fixed maturity security, available for sale, or identify an impaired fixed maturity security, available for sale, for which it is more likely than not we will be required to sell before anticipated recovery, the difference between the fair value and the amortized cost is included in other investment gains (losses) and the fair value becomes the new amortized cost. The new cost basis is not adjusted for any subsequent recoveries in fair value. The Company reports accrued investment income separately from fixed maturities, available for sale, and has elected not to measure an allowance for credit losses for accrued investment income. Accrued investment income is written off through net investment income at the time the issuer of the bond defaults or is expected to default on payments. Future events may occur, or additional information may become available, which may necessitate future realized losses in our portfolio. Significant losses could have a material adverse effect on our consolidated financial statements in future periods.
Policyholder account balances	Policyholder account balances represent the contract value that has accrued to the benefit of the policyholder as of the balance sheet date. It includes the accumulated account deposits, plus interest credited, less policyholder withdrawals and, if applicable, charges assessed. This balance also includes liabilities for the funding agreement-backed notes ("FABN"). Total liabilities for insurance products related to our fixed indexed annuities are comprised of: (i) the liability related to the host contract; and (ii) the fair market value of the embedded derivatives as summarized below (dollars in millions): June 30, December 31, Fixed indexed annuity insurance liabilities: Host contract liability $ 8,753.4 $ 8,487.0 Embedded derivatives at fair value 1,418.0 1,376.7 Total fixed indexed annuity insurance liabilities $ 10,171.4 $ 9,863.7 For presentation in the consolidated balance sheet, the total fixed indexed annuity insurance liability balance is bifurcated between: (i) policyholder account balances (which is the total of all current balances accruing to the policyholder under the terms and conditions of the policies assuming the contracts will continue in force); and (ii) the difference between the total fixed indexed annuity insurance liabilities summarized above and the policyholder account balances, which is classified as future policy benefits. These classifications are summarized below (dollars in millions): June 30, December 31, Policyholder account balances $ 10,409.5 $ 10,138.6 Future policy benefits (238.1) (274.9) Total fixed indexed annuity insurance liabilities $ 10,171.4 $ 9,863.7 When the total policyholder account balance exceeds the total fixed indexed annuity insurance liabilities, a negative future policy benefit balance will occur.
Earnings Per Share	Basic earnings per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period.  Restricted shares (including our performance units) are not included in basic earnings per share until vested.  Diluted earnings per share reflect the potential dilution that could occur if outstanding stock options were exercised and restricted stock was vested.  The dilution from options and restricted shares is calculated using the treasury stock method.  Under this method, we assume the proceeds from the exercise of the options (or the unrecognized compensation expense with respect to restricted stock and performance units) will be used to purchase shares of our common stock at the average market price during the period, reducing the dilutive effect of the exercise of the options (or the vesting of the restricted stock and performance units).
Business Segments	We view our operations as three insurance product lines (annuity, health and life) and the investment and fee income segments. Our segments are aligned based on their common characteristics, comparability of profit margins and the way management makes operating decisions and assesses the performance of the business. Our insurance product line segments (annuity, health and life) include marketing, underwriting and administration of the policies our insurance subsidiaries sell. The business written in each of the three product categories through all of our insurance subsidiaries is aggregated allowing management and investors to assess the performance of each product category. When analyzing profitability of these segments, we use insurance product margin as the measure of profitability, which is: (i) insurance policy income; and (ii) net investment income allocated to the insurance product lines; less (i) insurance policy benefits and interest credited to policyholders; and (ii) amortization of deferred acquisition costs and present value of future profits, non-deferred commissions and advertising expense. Net investment income is allocated to the product lines using the book yield of investments backing the block of business, which is applied to the average net insurance liabilities for the block in each period. Net insurance liabilities for the purpose of allocating investment income to product lines are equal to: (i) policyholder account balances for annuity products; (ii) total reserves before the fair value adjustments reflected in accumulated other comprehensive income (loss), if applicable, for all other products; less (iii) amounts related to reinsured business; (iv) deferred acquisition costs; (v) the present value of future profits; and (vi) the value of unexpired options credited to insurance liabilities. Income from insurance products is the sum of the insurance product margins of the annuity, health and life product lines, less expenses allocated to the insurance lines. It excludes the income from our fee income business, investment income not allocated to product lines, net expenses not allocated to product lines (primarily holding company expenses) and income taxes. Management believes insurance product margin and income from insurance products help provide a better understanding of the business and a more meaningful analysis of the results of our insurance product lines. We market our products through the Consumer and Worksite Divisions that reflect the customers served by the Company. The Consumer and Worksite Divisions are primarily focused on marketing insurance products, several types of which are sold in both divisions and underwritten in the same manner. The Consumer Division serves individual consumers, engaging with them on the phone, virtually, online, face-to-face with agents, or through a combination of sales channels. This structure unifies consumer capabilities into a single division and integrates the strength of our agent sales forces with one of the largest direct-to-consumer insurance businesses with proven experience in advertising, web/digital and call center support. The Worksite Division focuses on the sale of voluntary benefit life and health insurance products in the workplace for businesses, associations, and other membership groups, interacting with customers at their place of employment and virtually. The Worksite Division also offers employer benefits services that seek to increase benefits engagement and reduce costs for employers and their employees. These services include: benefit administration technology, year-round advocacy, enrollment, benefits compliance and communications services. The investment segment involves the management of our capital resources, including investments and the management of corporate debt and liquidity. Our measure of profitability of this segment is the total net investment income not allocated to the insurance products. Investment income not allocated to product lines represents net investment income less: (i) equity returns credited to policyholder account balances; (ii) the investment income allocated to our product lines; (iii) interest expense on notes payable, investment borrowings and financing arrangements; (iv) expenses related to the FABN program; and (v) certain expenses related to benefit plans that are offset by special-purpose investment income; plus (vi) the impact of annual option forfeitures related to fixed indexed annuity surrenders. Investment income not allocated to product lines includes investment income on investments in excess of amounts allocated to product lines, investments held by our holding companies, the spread we earn from our Federal Home Loan Bank ("FHLB") investment borrowing and FABN programs and variable components of investment income (including call and prepayment income, adjustments to returns on structured securities due to cash flow changes, income (loss) from company-owned life insurance ("COLI") and alternative investment income not allocated to product lines), net of interest expense on corporate debt and financing arrangements. The spread earned from our FHLB investment borrowing and FABN programs includes the investment income on the matched assets less: (i) interest on investment borrowings related to the FHLB investment borrowing program; (ii) interest credited on funding agreements; and (iii) amortization of deferred acquisition costs related to the FABN program. Our fee income segment includes the earnings generated from sales of third-party insurance products, services provided by Optavise, LLC ("Optavise") and the operations of our broker/dealer and registered investment advisor. Expenses not allocated to product lines include the expenses of our corporate operations, excluding interest expense on debt. We measure segment performance by excluding total investment gains (losses), changes in fair value of embedded derivative liabilities and MRBs, fair value changes related to the agent deferred compensation plan, income taxes and other non-operating items consisting primarily of earnings attributable to VIEs ("pre-tax operating earnings") because we believe that this performance measure is a better indicator of the ongoing business and trends in our business. Our primary investment focus is on investment income to support our liabilities for insurance products as opposed to the generation of investment gains (losses), and a long-term focus is necessary to maintain profitability over the life of the business. Investment gains (losses), changes in fair value of embedded derivative liabilities and MRBs, fair value changes related to the agent deferred compensation plan and other non-operating items consisting primarily of earnings attributable to VIEs depend on market conditions or represent unusual items that do not necessarily relate to the underlying business of our segments. Investment gains (losses) and changes in fair value of embedded derivative liabilities and MRBs may affect future earnings levels since our underlying business is long-term in nature and changes in our investment portfolio may impact our ability to earn the assumed interest rates needed to maintain the profitability of our business.
Fair Value Measurements	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, therefore, represents an exit price, not an entry price. We carry certain assets and liabilities at fair value on a recurring basis, including fixed maturities, equity securities, trading securities, investments held by VIEs, derivatives, separate account assets and embedded derivatives. We carry our COLI, which is invested in a series of mutual funds, at its cash surrender value which approximates fair value. In addition, we disclose fair value for certain financial instruments that are not carried at fair value, including mortgage loans, policy loans, cash and cash equivalents, insurance liabilities for interest-sensitive products and funding agreements, investment borrowings, notes payable and borrowings related to VIEs. The degree of judgment utilized in measuring the fair value of financial instruments is largely dependent on the level to which pricing is based on observable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our view of market assumptions in the absence of observable market information. Financial instruments with readily available active quoted prices would be considered to have fair values based on the highest level of observable inputs, and little judgment would be utilized in measuring fair value. Financial instruments that rarely trade would often have fair value based on a lower level of observable inputs, and more judgment would be utilized in measuring fair value. Valuation Hierarchy There is a three-level hierarchy for valuing assets or liabilities at fair value based on whether inputs are observable or unobservable. • Level 1 – includes assets and liabilities valued using inputs that are unadjusted quoted prices in active markets for identical assets or liabilities. Our Level 1 assets primarily include cash and cash equivalents and exchange-traded securities. • Level 2 – includes assets and liabilities valued using inputs that are quoted prices for similar assets in an active market, quoted prices for identical or similar assets in a market that is not active, observable inputs, or observable inputs that can be corroborated by market data. Level 2 assets and liabilities include those financial instruments that are valued by independent pricing services using models or other valuation methodologies. These models consider various inputs such as credit rating, maturity, corporate credit spreads, reported trades and other inputs that are observable or derived from observable information in the marketplace or are supported by transactions executed in the marketplace. Financial assets in this category primarily include: certain publicly registered and privately placed corporate fixed maturity securities; certain government or agency securities; certain mortgage and asset-backed securities; certain equity securities; most investments held by our consolidated VIEs; and derivatives such as call options. Financial liabilities in this category include investment borrowings, notes payable and borrowings related to VIEs. • Level 3 – includes assets and liabilities valued using unobservable inputs that are used in model-based valuations that contain management assumptions. Level 3 assets and liabilities include those financial instruments whose fair value is estimated based on broker/dealer quotes, pricing services or internally developed models or methodologies utilizing significant inputs not based on, or corroborated by, readily available market information. Financial assets in this category include certain corporate securities, certain structured securities, mortgage loans, and other less liquid securities. Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives (including embedded derivatives related to our fixed indexed annuity products and to a modified coinsurance arrangement), and funding agreements since their values include significant unobservable inputs including actuarial assumptions. At each reporting date, we classify assets and liabilities into the three input levels based on the lowest level of input that is significant to the measurement of fair value for each asset and liability reported at fair value. This classification is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction and overall market conditions. Our assessment of the significance of a particular input to the fair value measurement and the ultimate classification of each asset and liability requires judgment and is subject to change from period to period based on the observability of the valuation inputs. The vast majority of our assets carried at fair value use Level 2 inputs for the determination of fair value. These fair values are obtained primarily from independent pricing services, which use Level 2 inputs for the determination of fair value. Our Level 2 assets are valued as follows: • Fixed maturities available for sale, equity securities and trading securities Corporate securities are generally priced using market and income approaches using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads. U.S. Treasuries and obligations of U.S. Government corporations and agencies are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets and maturity. States and political subdivisions are generally priced using the market approach using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, new issuances and credit spreads. Foreign governments are generally priced using the market approach using independent pricing services. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, new issuances, benchmark yields, credit spreads and issuer rating. Asset-backed securities, agency and non-agency residential mortgage-backed securities, collateralized loan obligations and commercial mortgage-backed securities are generally priced using market and income approaches using independent pricing services. Inputs generally consist of quoted prices in inactive markets, spreads on actively traded securities, expected prepayments, expected default rates, expected recovery rates and issue specific information including, but not limited to, collateral type, seniority and vintage. Equity securities are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads. • Investments held by VIEs Corporate securities are generally priced using market and income approaches using pricing vendors. Inputs generally consist of issuer rating, benchmark yields, maturity, and credit spreads. • Other invested assets - derivatives The fair value measurements for derivative instruments, including embedded derivatives requiring bifurcation, are determined based on the consideration of several inputs including closing exchange or over-the-counter market price quotes, time value and volatility factors underlying options, market interest rates and non-performance risk. Third-party pricing services normally derive security prices through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. If there are no recently reported trades, the third-party pricing services may use matrix or model processes to develop a security price where future cash flow expectations are discounted at an estimated risk-adjusted market rate. The number of prices obtained for a given security is dependent on the Company's analysis of such prices as further described below. As the Company is responsible for the determination of fair value, we have control processes designed to ensure that the fair values received from third-party pricing sources are reasonable and the valuation techniques and assumptions used appear reasonable and consistent with prevailing market conditions. Additionally, when inputs are provided by third-party pricing sources, we have controls in place to review those inputs for reasonableness. As part of these controls, we perform monthly quantitative and qualitative analysis on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. The Company's analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) where available, a comparison of multiple pricing services' valuations for the same security; (iii) a review of month to month price fluctuations; (iv) a review to ensure valuations are not unreasonably dated; and (v) back testing to compare actual purchase and sale transactions with valuations received from third parties. As a result of such procedures, the Company may conclude a particular price received from a third-party is not reflective of current market conditions. In those instances, we may request additional pricing quotes or apply internally developed valuations. However, the number of such instances is insignificant and the aggregate change in value of such investments is not materially different from the original prices received. The categorization of the fair value measurements of our investments priced by independent pricing services was based upon the Company's judgment of the inputs or methodologies used by the independent pricing services to value different asset classes. Such inputs typically include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers and other relevant data. The Company categorizes such fair value measurements based upon asset classes and the underlying observable or unobservable inputs used to value such investments. For securities that are not priced by pricing services and may not be reliably priced using pricing models, we obtain broker quotes. These broker quotes are non-binding and represent an exit price, but assumptions used to establish the fair value may not be observable and therefore represent Level 3 inputs. Approximately 92 percent of our Level 3 fixed maturity securities and trading securities were valued using unadjusted broker quotes or broker-provided valuation inputs. The remaining Level 3 fixed maturity investments do not have readily determinable market prices and/or observable inputs. For these securities, we use internally developed valuations. Key assumptions used to determine fair value for these securities may include risk premiums, projected performance of underlying collateral and other factors involving significant assumptions which may not be reflective of an active market. For certain investments, we use a matrix or model process to develop a security price where future cash flow expectations are discounted at an estimated market rate. The pricing matrix incorporates term interest rates as well as a spread level based on the issuer's credit rating, other factors relating to the issuer, and the security's maturity. In some instances issuer-specific spread adjustments, which can be positive or negative, are made based upon internal analysis of security specifics such as liquidity, deal size, and time to maturity.

(b) Such amount represents the difference between: (i) the total insurance liabilities for our fixed indexed annuities (including the host contract and the related embedded derivative); and (ii) the policyholder account balances for these products. The accounting requirement to bifurcate the embedded derivative and value it at the current estimated fair value results in this amount. (c) In certain instances for interest-sensitive products, the total insurance liabilities for a particular line of business may not be deficient in the aggregate to trigger loss recognition, but the pattern of earnings may be such that profits are expected to be recognized in earlier years followed by losses in later years. In these situations, accounting standards require that an additional liability (the "future loss reserve") be recognized by an amount necessary to sufficiently offset the losses that would be recognized in later years.

Schedule of Fair Value Measurement Inputs	The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at June 30, 2024 (dollars in millions): Fair value at June 30, 2024 Valuation techniques Unobservable inputs Range (weighted average) (a) Assets: Corporate securities (b) $ 2.5 Recovery method Percent of recovery expected (25.00%) Corporate securities (c) 1.5 Unadjusted purchase price Not applicable Not applicable Asset-backed securities (d) 8.2 Discounted cash flow analysis Discount margins (1.98%) Equity securities (e) 63.6 Market comparables EBITDA multiples 10.8X Equity securities (f) 9.3 Unadjusted purchase price Not applicable Not applicable Other assets categorized as Level 3 (g) 210.0 Unadjusted third-party price source Not applicable Not applicable Market risk benefit asset (h) 84.5 Discounted cash flow analysis Surrender rates 1.42% - 15.25% (4.28%) Utilization rates 5.92% - 47.62% (24.88%) Total 379.6 Liabilities: Market risk benefit liability (h) 3.2 Discounted cash flow analysis Surrender rates 1.42% - 15.25% (4.28%) Utilization rates 5.92% - 47.62% (24.88%) Embedded derivatives related to fixed indexed annuity products (i) 1,418.0 Discounted projected embedded derivatives Projected portfolio yields 4.32% - 4.92% (4.57%) Discount rates 4.26% - 5.83% (4.91%) Surrender rates 1.42% - 23.70% (6.92%) ________________________________ (a) The weighted average is based on the relative fair value of the related assets or liabilities. (b) Corporate securities - The significant unobservable input used in the fair value measurement of these corporate securities is percentage of recovery expected. Significant increases (decreases) in percentage of recovery expected in isolation would have resulted in a significantly higher (lower) fair value measurement. (c) Corporate securities - For these assets, there were no adjustments to the purchase price. (d) Asset-backed securities - The significant unobservable input used in the fair value measurement of these asset-backed securities is discount margin added to a risk-free market yield. Significant increases (decreases) in discount margin in isolation would have resulted in a significantly lower (higher) fair value measurement. (e) Equity securities - The significant unobservable input used in the fair value measurement of these equity securities is multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"). Generally, increases (decreases) in the EBITDA multiples would result in higher (lower) fair value measurements. (f) Equity securities - For these assets, there were no adjustments to the purchase price. (g) Other assets categorized as Level 3 - For these assets, there were no adjustments to non-binding quoted market prices obtained from third-party pricing sources. (h) Market risk benefits – Many of our fixed indexed annuity products include a GLWB that is considered a MRB. The calculation of the value of MRBs is based on significant unobservable inputs including assumptions related to surrenders and utilization of policy benefits. These assumptions are based on actuarial estimates and past experience. Increases in assumed surrender rates would generally increase the value of a MRB asset or decrease the value of a MRB liability (with decreases in assumed surrender rates having the opposite impacts). Increases in utilization rates would generally decrease the value of a MRB asset or increase the value of a MRB liability (with decreases in utilization rates having the opposite impacts). (i) Embedded derivatives related to fixed indexed annuity products (classified as policyholder account liabilities) - The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed indexed annuity products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would have resulted in a higher (lower) fair value measurement. The discount rate is based on risk free rates (U.S. Treasury rates for similar durations) adjusted for our non-performance risk and risk margins for non-capital market inputs. Increases (decreases) in the discount rates would have resulted in a lower (higher) fair value measurement. Assumed surrender rates are used to project how long the contracts remain in force. Generally, the longer the contracts are assumed to be in force the higher the fair value of the embedded derivative. The embedded derivatives related to fixed indexed annuity products are classified in policyholder account balances and future policy benefits as presented in the note to the consolidated financial statements entitled "Accounting for Derivatives". The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at December 31, 2023 (dollars in millions): Fair value at December 31, 2023 Valuation techniques Unobservable inputs Range (weighted average) (a) Assets: Corporate securities (b) $ 2.9 Discounted cash flow analysis Discount margins (2.22%) Corporate securities (c) 2.5 Recovery method Percent of recovery expected (25.00%) Corporate securities (d) 1.5 Unadjusted purchase price Not applicable Not applicable Asset-backed securities (e) 8.6 Discounted cash flow analysis Discount margins (2.24%) Equity securities (f) 63.4 Market comparables EBITDA multiples 11.3X Equity securities (g) .1 Recovery method Percent of recovery expected 0.00% - 100.00% (100.00%) Equity securities (h) 9.2 Unadjusted purchase price Not applicable Not applicable Other assets categorized as Level 3 (i) 213.9 Unadjusted third-party price source Not applicable Not applicable Market risk benefit asset (j) 75.4 Discounted cash flow analysis Surrender rates 1.42% - 15.25% (4.28%) Utilization rates 5.92% - 47.62% (24.88%) Total 377.5 Liabilities: Market risk benefit liability (j) 7.4 Discounted cash flow analysis Surrender rates 1.42% - 15.25% (4.28%) Utilization rates 5.92% - 47.62% (24.88%) Embedded derivatives related to fixed indexed annuity products (k) 1,376.7 Discounted projected embedded derivatives Projected portfolio yields 4.32% - 4.92% (4.57%) Discount rates 3.85% - 5.76% (4.41%) Surrender rates 1.42% - 23.70% (6.92%) ________________________________ (a) The weighted average is based on the relative fair value of the related assets or liabilities.
