Organization, Consolidation and Presentation of Financial Statements [Abstract]  
BUSINESS, BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES BUSINESS, BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES
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 and financial services 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, 2024 consolidated balance sheet data was derived from the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K. Accordingly, these interim consolidated financial statements should be read together with the consolidated financial statements included in our 2024 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, guaranty fund assessment accruals, goodwill and intangible assets, and fee revenue.  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.
Goodwill and Intangible Assets

In February 2021, we acquired DirectPath, LLC ("DirectPath", now known as Optavise, LLC ("Optavise") subsequent to its name change in April 2022). In April 2019, we acquired Web Benefits Design Corporation ("WBD"), which was subsequently merged into Optavise during 2023. Optavise provides personalized benefits education, advocacy and transparency, and communications services that help employers reduce healthcare costs and assist employees with making informed benefits decisions. Optavise goodwill and other intangible assets arising from the acquisitions are reflected in our Fee income segment.

Intangible assets with definite lives are amortized over their estimated useful lives and are reviewed for impairment if indicators of impairment arise. When such indicators are present, intangible assets are first tested for recoverability in accordance with Accounting Standards Codification (ASC) 360, Property, Plant, and Equipment. If the assets are not recoverable, an impairment loss is recorded, measured as the difference between the assets' fair value and their carrying value. Goodwill is tested annually for impairment and whenever indicators of impairment arise in accordance with ASC 350, Intangibles - Goodwill and Other. The Company first performs a qualitative assessment to determine whether it is more likely than not a goodwill impairment exists, and if an indication of potential impairment results from the qualitative assessment, a quantitative assessment is performed. The Company prepares a quantitative assessment to determine the fair value of the reporting unit by using a combination of the present value of expected future cash flows and a market approach based on revenue-multiple data from peer companies and relevant observable market transactions, if available. If an impairment is
identified, a write-off is recorded by the amount that the carrying value exceeds the fair value of the reporting unit up to the carrying amount of goodwill and intangible assets.

Macroeconomic, industry and market conditions, both current and future expected financial performance, and relevant entity-specific events in the three months ended September 30, 2025 caused us to consider whether there were any interim indicators of impairment. As a result of this evaluation, we identified that the valuation of Optavise would more likely than not be impacted by the recent decline in value of comparable publicly traded companies. This, combined with lower than anticipated revenue in the quarter and trends for future periods led us to conclude that there were indicators of impairment and we accordingly prepared a quantitative assessment. The Company determined the fair value of the reporting unit by using a combination of the present value of expected future cash flows and a market approach based on earnings multiple data from peer companies, using unobservable level 3 inputs.

As a result of the quantitative assessment performed, the Company concluded that goodwill of $69.5 million and other assets, primarily intangible assets, of $27.2 million were fully impaired as of September 30, 2025. The total impairment charge of $96.7 million is included in the accompanying consolidated statement of comprehensive income for the three and nine months ended September 30, 2025.
Recently Adopted Accounting Standards

We adopted Accounting Standards Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable
Segment Disclosures ("ASU 2023-07") effective January 1, 2024. 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 Financial Accounting Standards Board ("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. The adoption of ASU
2023-07 did not have an impact on our financial position or results of operations, and did not have a material impact on our
disclosures. The adoption was made retrospectively.
Recently Issued Accounting Standards

In September 2025, the FASB issued Accounting Standards Update 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software ("ASU 2025-06"). This update removes all references to prescriptive and sequential software development stages, and adds that entities are required to start capitalizing software costs when both of the following occur: 1) management has authorized and committed to funding the software project, and 2) it is probable that the project will be completed and the software will be used to perform the function intended. The update also removes Subtopic 350-50, Website Development Costs, and incorporates that guidance within Subtopic 350-40. ASU 2025-06 is effective for annual periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. Early adoption is permitted. Entities will have the option to apply the updates prospectively, under a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption, or retrospectively. We are currently evaluating the effect of ASU 2025-06 on our consolidated financial statements and related disclosures.

In July 2025, the FASB issued Accounting Standards Update 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update provides a practical expedient for entities when estimating expected credit losses to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 is effective for annual periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods. Early adoption is permitted. ASU 2025-05 should be applied prospectively. We are currently evaluating the effect of ASU 2025-05 on our consolidated financial statements and related disclosures.
In November 2024, the FASB issued Accounting Standards Update 2024-03, Income Statement—Reporting
Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement
Expenses (“ASU 2024-03”), which requires disclosure of additional information about specific expense categories in the
notes to the financial statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and for
interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. ASU 2024-03 may be
applied retrospectively or prospectively. The adoption of ASU 2024-03 will modify our disclosures but will not have an impact on our financial position or results of operations. We do not expect the impact to our disclosures to be material.

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 after December 15, 2024, 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.
Revision of Prior Period Amounts

As previously disclosed, certain amounts presented in the prior years’ consolidated statement of operations for the three and nine months ended September 30, 2024, consolidated balance sheet as of December 31, 2024, consolidated statement of shareholders’ equity as of December 31, 2024 and related footnotes thereto have been corrected to conform with the current period presentation. During the fourth quarter of 2024, the Company corrected certain immaterial errors that resulted in misclassifications related to market risk benefits.

Upon the adoption of Accounting Standards Update 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, the Company recorded the fair value of the market risk benefit ("MRB") in policyholder account balances, resulting in no initial MRB presented separately on the consolidated balance sheet. MRBs are required to be presented separately in the consolidated balance sheet. Subsequent to transaction inception, the resulting accumulated change in the fair value of the MRBs was recorded as market risk benefits within the consolidated balance sheet. Additionally, the transaction’s resulting policyholder account balance discount was accreted in change in fair value of MRBs. This accretion should have been recorded in insurance policy benefits within the consolidated statement of operations.

To correct for the error, the Company increased insurance policy benefits and decreased change in value of market benefits by $4.8 million within the consolidated statement of operations for the three months ended September 30, 2024, and the Company increased insurance policy benefits and decreased change in fair value of market risk benefits by $15.6 million within the consolidated statement of operations for the nine months ended September 30, 2024.

In addition, the Company identified an immaterial overstatement of its policy holder account balances and insurance policy benefits recorded for the year ended December 31, 2024 and the quarter ended March 31, 2025 related to the calculation of the embedded derivative for its flexible premium bonus indexed annuity product. This error caused the embedded derivative to be overstated as of these periods by $21.6 million and $31.7 million, respectively. The correction of these errors had no impact on our statement of cash flows or segment results for the periods reported.

Finally, the consolidated balance sheet for the year ended December 31, 2024 has been revised to correct immaterial errors related to the classification of non-redeemable preferred stock and to reflect an unsettled investment trade by one of our variable interest entities ("VIEs"). To correct for these errors, fixed maturities, available for sale, at fair value was decreased by $110.4 million with a corresponding increase to equity securities at fair value, and investments held by variable interest entities increased $1.5 million with a corresponding increase to other liabilities.
The Company assessed the materiality of these errors on prior period consolidated financial statements and determined that such financial statements were not materially misstated. Accordingly, the Company corrected these immaterial errors in this Quarterly Report on Form 10-Q. The following tables present the impact of the correction of the immaterial errors related to the overstatement of policy holder account balances and insurance policy benefits recorded, the classification of non-redeemable preferred stock and to reflect an unsettled investment trade by one of our variable interest entities for the year ended December 31, 2024 and for the three months ended March 31, 2025 (in millions):

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 in the consolidated statement of operations. The change in fair value of securities with embedded derivatives is recognized in other investment gains (losses) in the consolidated statement of operations.

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 over-
collateralization, 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 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 uncollectible, 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 September 30, 2025, 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):

Gross Unrealized Investment Losses

Our investment strategy is to manage, over a sustained period and within acceptable parameters of quality and risk, capital efficiency through active strategic asset allocation and investment management. 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.
The following table summarizes the gross unrealized losses and fair values of our investments with unrealized losses for which an allowance for credit losses has not been recorded, aggregated by investment category and length of time that such securities have been in a continuous unrealized loss position at September 30, 2025 (dollars in millions):

Based on management's current assessment of investments with unrealized losses at September 30, 2025, the Company believes the issuers of the securities will continue to meet their obligations.  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.

Mortgage Loans

Mortgage loans are carried at amortized unpaid balance, net of allowance for estimated credit losses. 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 September 30, 2025, we held commercial mortgage loan investments with an amortized cost and fair value of $1,674.0 million and $1,577.1 million, respectively. At September 30, 2025, there were no commercial mortgage loans that were non-current or in the process of 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 September 30, 2025 (dollars in millions):

________________
(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.

At September 30, 2025, we held residential mortgage loan investments with an amortized cost and fair value of $1,389.8 million and $1,366.0 million, respectively. We consider current or non-current loan status as our primary credit quality indicator in conjunction with other quantitative and qualitative factors. We define non-current loans as those that are 90 or more days past-due and/or in nonaccrual status. At September 30, 2025, there were 24 residential mortgage loans that were non-current with an amortized cost of $17.7 million (of which, five loans with an amortized cost of $3.7 million were in foreclosure).

(b)    Other changes in fair value are comprised of (i) gains related to certain other invested assets and fixed maturity investments with embedded derivatives, including the change in fair value, of nil and $8.1 million for the three months ended September 30, 2025 and 2024, respectively, and $7.1 million and $25.2 million for the nine months ended September 30, 2025 and 2024, respectively; and (ii) the increase in fair value of embedded derivatives related to a modified coinsurance agreement of $0.5 million and $1.7 million for the three months ended September 30, 2025 and 2024, respectively, and $1.8 million and $1.9 million for the nine months ended September 30, 2025 and 2024, respectively.
(c)    Changes in the estimated fair value of fixed maturity investments with embedded derivatives that we have elected the fair value option (that are still held as of the end of the respective periods) were $3.0 million and $6.1 million for the three months ended September 30, 2025 and 2024, respectively, and $10.1 million and $10.8 million for the nine months ended September 30, 2025 and 2024, respectively.

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.

During the three months ended September 30, 2025, the $18.1 million of gross realized losses on sales of $349.1 million of fixed maturity securities, available for sale, primarily related to various corporate securities. Securities are generally sold at a loss following unforeseen sector or issuer-specific events or conditions, shifts in perceived credit quality relative values, or in connection with strategic asset repositionings related to changes in market conditions.

During the nine months ended September 30, 2025, the $42.7 million of gross realized losses on sales of $874.2 million of fixed maturity securities, available for sale, primarily related to various corporate securities.
During the three months ended September 30, 2024, the $12.8 million of gross realized losses on sales of $561.1 million of fixed maturity securities, available for sale, primarily related to various corporate securities and commercial mortgage-backed securities.

During the nine months ended September 30, 2024, the $46.3 million of gross realized losses on sales of $1,230.3 million of fixed maturity securities, available for sale, primarily related to various corporate securities, asset backed securities, and 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.
At September 30, 2025, the amortized cost and carrying value of fixed maturities that were non-income producing were $5.7 million and $3.8 million, respectively.

FAIR VALUE MEASUREMENTS

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 company-owned life insurance ("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, policy loans and other less liquid securities.  Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives and MRB related to our fixed indexed annuity products, and 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 independent 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 observable market 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. 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 98 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 September 30, 2025 is as follows (dollars in millions):
 Quoted prices in active markets

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses during the time the applicable financial instruments were classified as Level 3. Realized and unrealized gains (losses) on Level 3 assets are primarily reported in either net investment income for policyholder and other special-purpose portfolios or investment gains (losses) within the consolidated statement of operations; or accumulated other comprehensive loss within shareholders' equity based on the appropriate accounting treatment for the instrument. The amount presented for gains (losses) included in our net income for assets held as of the reporting date primarily represents: (i) the change in the allowance for credit losses for fixed maturities, available for sale; and (ii) changes in fair value of equity securities and trading securities that are held as of the reporting date. The amount presented for gains (losses) included in other comprehensive loss for assets held as of the reporting date primarily represents changes in the fair value of fixed maturities, available for sale, that are held as of the reporting date.

At September 30, 2025, 91 percent of our Level 3 fixed maturities, available for sale, were investment grade and 82 percent of our Level 3 fixed maturities, available for sale, consisted of corporate securities.

(a)    The weighted average is based on the relative fair value of the related assets or liabilities.
(b)    Asset-backed securities - The significant unobservable input used in the fair value measurement of these asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would have resulted in a significantly lower (higher) fair value measurement.
(c)    Asset-backed 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.
(d)    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.
(e)    Market risk benefits – Many of our fixed indexed annuity products include a guaranteed living withdrawal benefit ("GLWB") that is considered a MRB. The calculation of the value of MRBs is based on significant unobservable inputs including nonmarket assumptions related to surrender rates, partial withdrawal rates, mortality and GLWB utilization. These assumptions are based on actuarial estimates and past experience. Increases in assumed surrender rates would generally decrease the value of a MRB liability. Increases in partial withdrawal rates would generally decrease the value of a MRB liability. A decrease in the mortality assumption would generally increase the MRB liability. Increases in utilization rates would generally increase the value of a MRB liability. Increases in non-performance risk spread decrease the MRB liability.
(f)    Embedded derivatives related to fixed indexed annuity products are classified as policyholder account liabilities on the consolidated balance sheet. The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed indexed annuity products are surrender rates, partial withdrawal rates, mortality, GLWB utilization, option budget, and non-performance risk. Assumed surrender rates, partial withdrawal rates, and mortality 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. Increases (decreases) in utilization rates would generally increase (decrease) the value of the embedded derivative.Increases (decreases) in option budget in isolation would have resulted in a higher (lower) fair value measurement. Increases in non-performance risk spread result in a lower fair value measurement.

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 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 third quarter of 2025 and 2024, we reviewed our actual experience and updated our assumptions for future cash flows. The impact of updating these assumptions is reflected in the "Effect of changes in cash flow assumptions" line items in the tables below.
The following tables summarize balances and changes in the liability for future policy benefits for traditional and limited-payment contracts for the nine months ended September 30, 2025 (dollars in millions):

Many of our fixed indexed annuity products include a GLWB that is considered a 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.

In the third quarter of 2025 and 2024, we reviewed our nonmarket assumptions used to calculate the MRBs and determined updates were warranted. The impact of updating these assumptions is reflected in the “Effect of changes in future expected policyholder behavior” line items in the table below.

Weighted average shares outstanding for diluted earnings per share98,553 107,131 100,670 109,078 
Basic earnings per common share is computed by dividing net income 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

Segment Reporting [Abstract]  
BUSINESS SEGMENTS BUSINESS SEGMENTS
We view our operations as three insurance product line segments (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 the CODM makes operating decisions and assesses the performance of the business. Our CODM is the Chief Executive Officer.

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; (ii) interest credited to policyholders; (iii) amortization of deferred acquisition costs and present value of future profits, non-deferred commissions; and (iv) 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 values for interest sensitive 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 product 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 an additional 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 Bankers Life and Casualty Company ("Bankers Life") funding agreement backed note ("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 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 (primarily Medicare Advantage), services provided by Optavise, LLC ("Optavise") and the operations of our broker-dealer and registered investment advisor. The resulting fee income metric is the fee income segment's measure of profitability.

Our CODM allocates resources and assesses the performance of each operating segment based on the respective
product line insurance margin, investment income not allocated, and fee income metrics described above.

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, costs related to our three-year project to modernize certain elements of our technology ("TechMod"), goodwill and other asset impairment expenses and other non-operating items including 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.

Policyholder account balances$1,598.4 $1,471.6 

Our fixed indexed annuity products provide a guaranteed minimum rate of return on the fixed fund portion of the contracts and a higher potential return on the index portion of the contract that is based on a percentage (the "participation rate") of the amount of increase in the value of a particular index, such as the Standard & Poor's 500 Index, over a specified period.  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. We are required to record the embedded derivatives related to our fixed indexed annuity products at estimated fair value. 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 $4.4 billion and $4.2 billion at September 30, 2025 and December 31, 2024, 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 $71.6 million in underlying investments held by the ceding reinsurer at September 30, 2025.

We purchase certain fixed maturity securities that contain embedded derivatives that are required to be held at fair value on the consolidated balance sheet. In these instances, we generally elect the fair value option to carry these securities at fair value with changes in fair value recognized in net income.

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.

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 results in a tax deduction of certain indirect costs previously capitalized under the Company's prior method of accounting. 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 formal IRS approval was not required. The Company requested approval for its tax method change in June 2024. At December 31, 2024, the Company had not yet received approval from the IRS and was therefore required to account for the existing tax assets under the prior tax method of accounting. In March 2025, the Company executed a consent agreement with the IRS that provides formal approval for the tax method change. As a result, the Company recharacterized the remaining $797.6 million of capitalized indirect costs under the prior accounting method to a net operating loss carryforward ("NOL") with no expiration date.

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 net deferred tax assets of $690.6 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.

Section 382 of the Internal Revenue Code (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 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 (3.71 percent at September 30, 2025), 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 September 30, 2025, we were below the 50 percent ownership change level that could limit our ability to utilize our NOLs.

We have $977.3 million of federal non-life NOLs as of September 30, 2025, as summarized below (dollars in millions):
Year of expirationTotal
NOLs expiring in 2029 through 2035$150.4 
NOLs with no expiration date826.9 
Total$977.3 

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 $4.4 million at September 30, 2025 and December 31, 2024, respectively, primarily resulting from the tax method change discussed previously.  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 Company had a capital loss carryforward of $30.9 million and $5.6 million at September 30, 2025 and December 31, 2024, respectively. Capital loss carryforwards can be carried forward for up to five years to offset future capital gains. We expect this carryforward to be fully utilized prior to the expiration date in 2030.

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 2024. 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 resolved in a manner consistent with management’s expectations, the Company may be required to adjust its provision for income taxes.

On July 4, 2025, the One Big Beautiful Bill Act of 2025 was enacted in the United States, which among other things, provides permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. These changes will primarily impact the timing of our tax deductions; however, we do not expect these provisions to have a material impact on our financial position or results of operations.

Credit Agreement

On May 8, 2025, the Company entered into a sixth amendment and restatement agreement (the "Credit Agreement") with respect to its existing credit agreement. The $250.0 million 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 15.0 percent of total capitalization) of not more than 35.0 percent (such ratio was 24.0 percent at September 30, 2025); and (ii) a minimum consolidated net worth of not less than the sum of (x) $2,674.0 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, including the conversion of debt securities of the Company into Equity interests (the Company's consolidated net worth was $3,729.9 million at September 30, 2025 compared to the minimum requirement of $2,674.3 million). The maturity date of the Credit Agreement is May 8, 2030. The Credit Agreement contains certain other restrictive covenants with which the Company must comply. The interest rate applicable to loans under the Credit Agreement is calculated as the Secured Overnight Financing Rate ("SOFR") or the base rate (as defined in the Credit Agreement), at the Company's option, plus a margin based on the Company's unsecured debt rating. The applicable margins under the Credit Agreement range from 1.125 percent to 1.750 percent, in the case of loans at the SOFR, and 0.125 percent to 0.750 percent, in the case of loans at the base rate. The commitment fee under the Credit Agreement is based on the Company's unsecured debt rating. The Credit Agreement also provides that the Company may incur up to $200 million of incremental loans (which may include new term loans), subject to conditions that are set forth therein. There are no term loans outstanding under the Credit Agreement as of September 30, 2025. There were no amounts outstanding under the Credit Agreement during the nine months ended September 30, 2025.

INVESTMENT BORROWINGS INVESTMENT BORROWINGS
Three of the Company's insurance subsidiaries (Bankers Life, Washington National Insurance Company ("Washington National") and Colonial Penn Life Insurance Company ("Colonial Penn")) are members of the FHLB.  As members of the FHLB, our insurance subsidiaries have the ability to borrow on a collateralized basis from the FHLB. 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 September 30, 2025, the carrying value of the FHLB common stock was $109.3 million.  As of September 30, 2025, collateralized borrowings from the FHLB totaled $2.4 billion and the proceeds were used to purchase matched 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 $3.4 billion at September 30, 2025, 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.

Generally, the variable and fixed rate borrowings are pre-payable.  At September 30, 2025, the aggregate prepayment penalty on such outstanding borrowings was not material.

Interest expense of $83.4 million and $94.6 million during the nine months ended September 30, 2025 and 2024, respectively, was recognized related to total borrowings from the FHLB, reflecting lower interest rates on the variable rate investment borrowings partially offset by higher average investment borrowings during the nine months ended September 30, 2025.

Equity [Abstract]  
SHAREHOLDERS' EQUITY SHAREHOLDERS' EQUITY
During the nine months ended September 30, 2025, we repurchased 6.7 million shares of common stock for $259.9 million under our securities repurchase program (including $1.0 million of repurchases settled in the fourth quarter of 2025). The Company had remaining repurchase authority of $480.4 million as of September 30, 2025.

During the nine months ended September 30, 2025, we issued 0.9 million shares of common stock, net of shares withheld to pay tax withholdings, pursuant to employee benefit plans.

During the nine months ended September 30, 2025, dividends declared on common stock totaled $50.0 million ($0.50 per common share). In May 2025, the Company increased its quarterly common stock dividend to $0.17 per share from $0.16 per share.

Accumulated other comprehensive loss, included in shareholders' equity as of September 30, 2025 and December 31, 2024, is comprised of the following (dollars in millions):

LITIGATION AND OTHER LEGAL PROCEEDINGS

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 Beechwood Re Ltd. ("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 Plaintiffs' motion to remand the case back to the Delaware Chancery Court. On July 10, 2020, Plaintiffs filed an Amended Complaint and the CNO Parties 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. Under the existing Case Schedule, trial is scheduled to commence in April 2026.

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") and other provisions 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. On September 25, 2024, the Court granted in part and denied in part the CNO Entities' Motion for Summary Judgment on the breach of contract claim. On November 12, 2024, the Court granted CNO Entities' Motion to Bifurcate the trials of the breach
of contract and alter ego claims. On May 7, 2025, the CNO Entities conceded that certain actions by Conseco Life Insurance Company breached the policies’ terms; the CNO Entities maintain that such breaches did not cause any damages to Plaintiffs. A three-day jury trial on causation and damages as to the two class representatives commenced on June 16, 2025, and the jury returned a verdict in favor of the class representatives on June 18, 2025 for approximately $0.2 million collectively. This verdict is notional and contingent and has no preclusive effect on any follow on trials by absent class members in terms of causation and damages. The class representatives' ability to collect any damages from the CNO Entities will depend on the outcome of the bench trial on alter ego liability. The bench trial on alter ego liability was held between August 26 to September 2, 2025, but no ruling has been made yet. The parties are currently preparing post-trial briefing, which is anticipated to be concluded by mid-November. Any liability of any kind will depend on the outcome of the alter ego trial, and in the event the court rules in favor of Plaintiffs on that issue, whether absent class members will participate in follow on trials to determine whether they are entitled to damages, and the outcome of those trials. The outcome of all trials will be subject to appeal. Because there is no final judgment in the case resulting from the jury trial, the CNO Entities cannot yet appeal the jury verdict, and all rights to appeal with respect to all issues have otherwise been preserved. Any follow on trials and appeals with respect to absent class members may take years to resolve. 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.

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 commercial bank 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):

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 September 30, 2025, such loans had an amortized cost of $298.6 million; gross unrealized gains of $0.5 million; gross unrealized losses of $1.8 million; allowance for credit losses of $0.5 million; and an estimated fair value of $296.8 million.

The following table summarizes changes in the allowance for credit losses related to corporate securities held by VIEs (dollars in millions):

The following table sets forth the amortized cost and estimated fair value of the investments held by the VIEs at September 30, 2025, 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.

During the nine months ended September 30, 2025, the VIEs recognized net investment losses of $6.1 million which were comprised of: (i) $6.9 million of net losses from the sales of fixed maturities and (ii) a decrease in the allowance for credit losses of $0.8 million. Such net realized losses included gross realized losses of $7.3 million from the sale of $88.2 million of investments.

During the nine months ended September 30, 2024, the VIEs recognized net investment losses of $12.5 million which were comprised of: (i) $17.7 million of net losses from the sales of fixed maturities; (ii) $3.9 million of gains related to the liquidation of a VIE; and (iii) an decrease in the allowance for credit losses of $1.3 million. Such net realized losses included gross realized losses of $18.9 million from the sale of $176.9 million of investments.

At September 30, 2025, there were no fixed maturity investments held by the VIEs in default.

At September 30, 2025, the VIEs held: (i) investments (for which an allowance for credit losses has not been recorded) with a fair value of $169.5 million and gross unrealized losses not deemed to have credit losses of $1.4 million that had been in an unrealized loss position for less than twelve months.

At December 31, 2024, the VIEs held: (i) investments (for which an allowance for credit losses has not been recorded) with a fair value of $183.2 million and gross unrealized losses of $0.9 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 $25.6 million and gross unrealized losses of $0.3 million that had been in an unrealized loss position for greater than twelve months.

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 September 30, 2025, we held investments of $598.3 million in various limited partnerships, in which we are not the primary beneficiary. These investments are included within other invested assets on the consolidated balance sheet and typically reported to us one quarter in arrears. At September 30, 2025, we had unfunded commitments to these partnerships totaling $639.4 million.  Our maximum exposure to loss on these investments is limited to the amount of our investment and any unfunded commitments.

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, guaranty fund assessment accruals, goodwill and intangible assets, and fee revenue.  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.
Goodwill and Intangible Assets
Goodwill and Intangible Assets

In February 2021, we acquired DirectPath, LLC ("DirectPath", now known as Optavise, LLC ("Optavise") subsequent to its name change in April 2022). In April 2019, we acquired Web Benefits Design Corporation ("WBD"), which was subsequently merged into Optavise during 2023. Optavise provides personalized benefits education, advocacy and transparency, and communications services that help employers reduce healthcare costs and assist employees with making informed benefits decisions. Optavise goodwill and other intangible assets arising from the acquisitions are reflected in our Fee income segment.

Intangible assets with definite lives are amortized over their estimated useful lives and are reviewed for impairment if indicators of impairment arise. When such indicators are present, intangible assets are first tested for recoverability in accordance with Accounting Standards Codification (ASC) 360, Property, Plant, and Equipment. If the assets are not recoverable, an impairment loss is recorded, measured as the difference between the assets' fair value and their carrying value. Goodwill is tested annually for impairment and whenever indicators of impairment arise in accordance with ASC 350, Intangibles - Goodwill and Other. The Company first performs a qualitative assessment to determine whether it is more likely than not a goodwill impairment exists, and if an indication of potential impairment results from the qualitative assessment, a quantitative assessment is performed. The Company prepares a quantitative assessment to determine the fair value of the reporting unit by using a combination of the present value of expected future cash flows and a market approach based on revenue-multiple data from peer companies and relevant observable market transactions, if available. If an impairment is
identified, a write-off is recorded by the amount that the carrying value exceeds the fair value of the reporting unit up to the carrying amount of goodwill and intangible assets.
Macroeconomic, industry and market conditions, both current and future expected financial performance, and relevant entity-specific events in the three months ended September 30, 2025 caused us to consider whether there were any interim indicators of impairment. As a result of this evaluation, we identified that the valuation of Optavise would more likely than not be impacted by the recent decline in value of comparable publicly traded companies. This, combined with lower than anticipated revenue in the quarter and trends for future periods led us to conclude that there were indicators of impairment and we accordingly prepared a quantitative assessment. The Company determined the fair value of the reporting unit by using a combination of the present value of expected future cash flows and a market approach based on earnings multiple data from peer companies, using unobservable level 3 inputs.
Recently Adopted/Issued Accounting Standards
Recently Adopted Accounting Standards

We adopted Accounting Standards Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable
Segment Disclosures ("ASU 2023-07") effective January 1, 2024. 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 Financial Accounting Standards Board ("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. The adoption of ASU
2023-07 did not have an impact on our financial position or results of operations, and did not have a material impact on our

In September 2025, the FASB issued Accounting Standards Update 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software ("ASU 2025-06"). This update removes all references to prescriptive and sequential software development stages, and adds that entities are required to start capitalizing software costs when both of the following occur: 1) management has authorized and committed to funding the software project, and 2) it is probable that the project will be completed and the software will be used to perform the function intended. The update also removes Subtopic 350-50, Website Development Costs, and incorporates that guidance within Subtopic 350-40. ASU 2025-06 is effective for annual periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. Early adoption is permitted. Entities will have the option to apply the updates prospectively, under a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption, or retrospectively. We are currently evaluating the effect of ASU 2025-06 on our consolidated financial statements and related disclosures.

In July 2025, the FASB issued Accounting Standards Update 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update provides a practical expedient for entities when estimating expected credit losses to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 is effective for annual periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods. Early adoption is permitted. ASU 2025-05 should be applied prospectively. We are currently evaluating the effect of ASU 2025-05 on our consolidated financial statements and related disclosures.
In November 2024, the FASB issued Accounting Standards Update 2024-03, Income Statement—Reporting
Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement
Expenses (“ASU 2024-03”), which requires disclosure of additional information about specific expense categories in the
notes to the financial statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and for
interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. ASU 2024-03 may be
applied retrospectively or prospectively. The adoption of ASU 2024-03 will modify our disclosures but will not have an impact on our financial position or results of operations. We do not expect the impact to our disclosures to be material.

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 after December 15, 2024, 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.
Revision of Prior Period Amounts
Revision of Prior Period Amounts

As previously disclosed, certain amounts presented in the prior years’ consolidated statement of operations for the three and nine months ended September 30, 2024, consolidated balance sheet as of December 31, 2024, consolidated statement of shareholders’ equity as of December 31, 2024 and related footnotes thereto have been corrected to conform with the current period presentation. During the fourth quarter of 2024, the Company corrected certain immaterial errors that resulted in misclassifications related to market risk benefits.

Upon the adoption of Accounting Standards Update 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, the Company recorded the fair value of the market risk benefit ("MRB") in policyholder account balances, resulting in no initial MRB presented separately on the consolidated balance sheet. MRBs are required to be presented separately in the consolidated balance sheet. Subsequent to transaction inception, the resulting accumulated change in the fair value of the MRBs was recorded as market risk benefits within the consolidated balance sheet. Additionally, the transaction’s resulting policyholder account balance discount was accreted in change in fair value of MRBs. This accretion should have been recorded in insurance policy benefits within the consolidated statement of operations.

To correct for the error, the Company increased insurance policy benefits and decreased change in value of market benefits by $4.8 million within the consolidated statement of operations for the three months ended September 30, 2024, and the Company increased insurance policy benefits and decreased change in fair value of market risk benefits by $15.6 million within the consolidated statement of operations for the nine months ended September 30, 2024.

In addition, the Company identified an immaterial overstatement of its policy holder account balances and insurance policy benefits recorded for the year ended December 31, 2024 and the quarter ended March 31, 2025 related to the calculation of the embedded derivative for its flexible premium bonus indexed annuity product. This error caused the embedded derivative to be overstated as of these periods by $21.6 million and $31.7 million, respectively. The correction of these errors had no impact on our statement of cash flows or segment results for the periods reported.
Finally, the consolidated balance sheet for the year ended December 31, 2024 has been revised to correct immaterial errors related to the classification of non-redeemable preferred stock and to reflect an unsettled investment trade by one of our variable interest entities ("VIEs"). To correct for these errors, fixed maturities, available for sale, at fair value was decreased by $110.4 million with a corresponding increase to equity securities at fair value, and investments held by variable interest entities increased $1.5 million with a corresponding increase to other liabilities.
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 in the consolidated statement of operations. The change in fair value of securities with embedded derivatives is recognized in other investment gains (losses) in the consolidated statement of operations.

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 over-
collateralization, 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 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 uncollectible, 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.
Earnings Per Share Basic earnings per common share is computed by dividing net income 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 line segments (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 the CODM makes operating decisions and assesses the performance of the business. Our CODM is the Chief Executive Officer.

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; (ii) interest credited to policyholders; (iii) amortization of deferred acquisition costs and present value of future profits, non-deferred commissions; and (iv) 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 values for interest sensitive 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 product 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 an additional 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 Bankers Life and Casualty Company ("Bankers Life") funding agreement backed note ("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 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 (primarily Medicare Advantage), services provided by Optavise, LLC ("Optavise") and the operations of our broker-dealer and registered investment advisor. The resulting fee income metric is the fee income segment's measure of profitability.

Our CODM allocates resources and assesses the performance of each operating segment based on the respective
product line insurance margin, investment income not allocated, and fee income metrics described above.

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, costs related to our three-year project to modernize certain elements of our technology ("TechMod"), goodwill and other asset impairment expenses and other non-operating items including 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 company-owned life insurance ("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, policy loans and other less liquid securities.  Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives and MRB related to our fixed indexed annuity products, and 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 independent 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 observable market 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. 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 98 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.

(a)Transfers into Level 3 are the result of unobservable inputs utilized within valuation methodologies for assets that were previously valued using observable inputs. Transfers out of Level 3 are due to the use of observable inputs in valuation methodologies as well as the utilization of independent pricing service information for certain assets that the Company is able to validate.
(b)Purchases, sales, issuances and settlements represent the activity that occurred during the period that results in a change of the asset but does not represent changes in fair value for the instruments held at the beginning of the period.  Such activity primarily consists of purchases and sales of fixed maturity and equity securities. There were no issuances or settlements during the three months ended September 30, 2025.

_________
(a)Transfers into Level 3 are the result of unobservable inputs utilized within valuation methodologies for assets that were previously valued using observable inputs. Transfers out of Level 3 are due to the use of observable inputs in valuation methodologies as well as the utilization of independent pricing service information for certain assets that the Company is able to validate.
(b)Purchases, sales, issuances and settlements represent the activity that occurred during the period that results in a change of the asset but does not represent changes in fair value for the instruments held at the beginning of the period.  Such activity primarily consists of purchases and sales of fixed maturity and equity securities.  There were no issuances or settlements during the nine months ended September 30, 2024.

________________________________
(a)    The weighted average is based on the relative fair value of the related assets or liabilities.
(b)    Asset-backed securities - The significant unobservable input used in the fair value measurement of these asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would have resulted in a significantly lower (higher) fair value measurement.
(c)    Asset-backed 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.
(d)    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.
(e)    Market risk benefits – Many of our fixed indexed annuity products include a guaranteed living withdrawal benefit ("GLWB") that is considered a MRB. The calculation of the value of MRBs is based on significant unobservable inputs including nonmarket assumptions related to surrender rates, partial withdrawal rates, mortality and GLWB utilization. These assumptions are based on actuarial estimates and past experience. Increases in assumed surrender rates would generally decrease the value of a MRB liability. Increases in partial withdrawal rates would generally decrease the value of a MRB liability. A decrease in the mortality assumption would generally increase the MRB liability. Increases in utilization rates would generally increase the value of a MRB liability. Increases in non-performance risk spread decrease the MRB liability.
(f)    Embedded derivatives related to fixed indexed annuity products are classified as policyholder account liabilities on the consolidated balance sheet. The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed indexed annuity products are surrender rates, partial withdrawal rates, mortality, GLWB utilization, option budget, and non-performance risk. Assumed surrender rates, partial withdrawal rates, and mortality 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. Increases (decreases) in utilization rates would generally increase (decrease) the value of the embedded derivative.Increases (decreases) in option budget in isolation would have resulted in a higher (lower) fair value measurement. Increases in non-performance risk spread result in a lower fair value measurement.
