BUSINESS AND BASIS OF PRESENTATION
BUSINESS AND BASIS OF PRESENTATION

The following notes should be read together with the notes to the consolidated financial statements included in our 2019 Annual Report on Form 10-K.

CNO Financial Group, Inc., a Delaware corporation ("CNO"), is a holding company for a group of insurance companies operating throughout the United States that develop, market and administer health insurance, annuity, individual life insurance and other insurance products.  The terms "CNO Financial Group, Inc.", "CNO", the "Company", "we", "us", and "our" as used in these financial statements refer to CNO and its subsidiaries.  Such terms, when used to describe insurance business and products, refer to the insurance business and products of CNO's insurance subsidiaries.

We focus on serving middle-income pre-retiree and retired Americans, which we believe are attractive, underserved, high growth markets.  We sell our products through three distribution channels: career 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").  We have reclassified certain amounts from the prior periods to conform to the 2020 presentation.  These reclassifications have no effect on net income or shareholders' equity.  Results for interim periods are not necessarily indicative of the results that may be expected for a full year, especially when considering the risks and uncertainties associated with the novel coronavirus ("COVID-19") and the impact it may have on our business, results of operations and financial condition. The COVID-19 pandemic has negatively impacted the U.S. and global economies, created significant volatility and disruption in the capital markets, dramatically increased unemployment levels and has fueled concerns that it will lead to a global recession. Depending on the duration and severity of the pandemic, we foresee the potential for adverse impacts related to, among other things: (i) sales results; (ii) insurance product margin; (iii) net investment income; (iv) invested assets; (v) regulatory capital; (vi) liabilities for insurance products; (vii) deferred acquisition costs; (viii) the present value of future profits; and (ix) income tax assets. The full extent to which COVID-19 will impact our business, results of operations and financial condition remains uncertain.

The balance sheet at December 31, 2019, presented herein, has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

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), other-than-temporary impairments of investments, assets and liabilities related to income taxes, liabilities for insurance products, liabilities related to litigation and guaranty fund assessment accruals.  If our future experience differs from these estimates and assumptions, our financial statements could be materially affected.

The accompanying financial statements 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.

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 tax and related adjustments, 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 realized investment gains (losses)).
Trading securities include: (i) investments purchased with the intent of selling in the near term to generate income; (ii) investments supporting certain insurance liabilities; and (iii) 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 and investments supporting insurance liabilities and reinsurance agreements is recognized in income from policyholder and other special-purpose portfolios (a component of net investment income). The change in fair value of securities with embedded derivatives is recognized in realized investment gains (losses). Investment income related to investments supporting certain insurance liabilities is substantially offset by the change in insurance policy benefits related to certain products.

When an available for sale fixed maturity security's fair value is below the amortized cost, the security is considered impaired. 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 and report the credit loss component in net realized investment gains (losses) limited to the difference between estimated fair value and amortized cost. The impairment related to all other factors (non-credit factors) is reported in accumulated other comprehensive income along with unrealized gains related to fixed maturity investments, available for sale, net of tax and related adjustments. The allowance is adjusted for any additional credit losses and subsequent recoveries. When recognizing an allowance associated with a credit loss, the cost basis is not adjusted. When we determine a security is uncollectable, the remaining amortized cost will be written off.

In determining the credit loss component, we discount the estimated cash flows on a security by security basis. We consider the impact of macroeconomic conditions on inputs used to measure the amount of credit loss. For most structured securities, cash flow estimates are based on bond-specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity, prepayment speeds and structural support, including overcollateralization, excess spread, subordination and guarantees. For corporate bonds, cash flow estimates are derived by considering asset type, rating, time to maturity, and applying an expected loss rate.
  
If we intend to sell an impaired fixed maturity security, available for sale, or identify an impaired fixed maturity security, available for sale, for which is it 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 net realized 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.

Accumulated other comprehensive income is primarily comprised of the net effect of unrealized appreciation (depreciation) on our investments.  These amounts, included in shareholders' equity as of September 30, 2020 and December 31, 2019, were as follows (dollars in millions):

(a)The present value of future profits is the value assigned to the right to receive future cash flows from contracts existing at September 10, 2003, the date Conseco, Inc., an Indiana corporation, emerged from bankruptcy.
At September 30, 2020, adjustments to the present value of future profits, deferred acquisition costs, insurance liabilities and deferred tax assets included $(8.9) million, $(132.8) million, $(189.8) million and $72.0 million, respectively, for premium deficiencies that would exist on certain blocks of business if unrealized gains on the assets backing such products had been realized and the proceeds from the sales of such assets were invested at then current yields.

At December 31, 2019, adjustments to the present value of future profits, deferred acquisition costs, insurance liabilities and deferred tax assets included $(12.2) million, $(26.8) million, $(96.5) million and $29.4 million, respectively, for premium deficiencies that would exist on certain blocks of business if unrealized gains on the assets backing such products had been realized and the proceeds from the sales of such assets were invested at then current yields.

Gross Unrealized Investment Losses

Our investment strategy is to maximize, over a sustained period and within acceptable parameters of quality and risk, investment income and total investment return 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, 2020 (dollars in millions):

Based on management's current assessment of investments with unrealized losses at September 30, 2020, 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.

At September 30, 2020, the mortgage loan balance was primarily comprised of commercial mortgage loans. At September 30, 2020, there was one commercial mortgage loan in process of foreclosure with a carrying value of $5.9 million and there were 25 residential mortgage loans that were noncurrent with a carrying value of $10.9 million (of which, 22 such loans with a carrying value of $10.4 million were in forbearance). Our commercial mortgage loan portfolio is comprised of large commercial mortgage loans. Our loans have risk characteristics that are individually unique. At September 30, 2020, we held residential mortgage loan investments with an amortized cost and fair value of $92.2 million and $92.3 million, respectively.
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, 2020 (dollars in millions):

(c)    The change in the estimated fair value of certain structured securities held at September 30, 2020 that we have elected the fair value option and classify as trading securities was $(1.2) million.

During the first nine months of 2020, we recognized net realized investment losses of $55.4 million, which were comprised of: (i) $15.5 million of net losses from the sales of investments; (ii) $8.8 million of losses related to equity securities, including the change in fair value; (iii) the decrease in fair value of certain fixed maturity investments with embedded derivatives of $1.5 million; (iv) the increase in fair value of embedded derivatives related to a modified coinsurance agreement of $1.8 million; and (v) an increase in the allowance for credit losses and other-than-temporary impairment losses of $31.4 million.

During the first nine months of 2019, we recognized net realized investment gains of $23.7 million, which were comprised of: (i) $6.2 million of net gains from the sales of investments; (ii) $5.1 million of losses on the dissolution of a VIE;(iii) $11.4 million of gains related to equity securities, including the change in fair value; (iv) the increase in fair value of certain fixed maturity investments with embedded derivatives of $10.3 million; (v) the increase in fair value of embedded derivatives related to a modified coinsurance agreement of $6.5 million; and (vi) $5.6 million of writedowns of investments for other than temporary declines in fair value recognized through net income.

Our fixed maturity investments are generally purchased in the context of various long-term strategies, including funding insurance liabilities, so we do not generally seek to generate short-term realized gains through the purchase and sale of such securities.  In certain circumstances, including those in which securities are selling at prices which exceed our view of their underlying economic value, or when it is possible to reinvest the proceeds to better meet our long-term asset-liability objectives, we may sell certain securities.

At September 30, 2020, there were no fixed maturity investments in default.

During the first nine months of 2020, the $51.3 million of gross realized losses on sales of $412.9 million of fixed maturity securities, available for sale included: (i) $15.8 million related to various corporate securities; (ii) $25.0 million related to commercial mortgage-backed securities; and (iii) $10.5 million related to various other investments. Securities are generally sold at a loss following unforeseen issuer-specific events or conditions or shifts in perceived relative values.  These reasons include but are not limited to: (i) changes in the investment environment, including changes in relative value among potential
investment strategies; (ii) expectation that the market value could deteriorate; (iii) our desire to reduce our exposure to an asset class, an issuer or an industry; (iv) prospective or actual changes in credit quality; or (v) changes in expected portfolio cash flows.

During the first nine months of 2019, the $53.4 million of gross realized losses on sales of $936.6 million of fixed maturity securities, available for sale, included: (i) $46.1 million related to various corporate securities; and (ii) $7.3 million related to various other investments.

During the first nine months of 2019, we recognized $5.6 million of impairment losses recorded in earnings on corporate securities due to issuer specific events.

Prior to January 1, 2020, we regularly evaluated all of our investments with unrealized losses for possible impairment.  Our assessment of whether unrealized losses were "other than temporary" required significant judgment.  Factors considered included: (i) the extent to which fair value was less than the cost basis; (ii) the length of time that the fair value had been less than cost; (iii) whether the unrealized loss was event driven, credit-driven or a result of changes in market interest rates or risk premium; (iv) the near-term prospects for specific events, developments or circumstances likely to affect the value of the investment; (v) the investment's rating and whether the investment was investment-grade and/or had been downgraded since its purchase; (vi) whether the issuer was current on all payments in accordance with the contractual terms of the investment and was expected to meet all of its obligations under the terms of the investment; (vii) whether we intended to sell the investment or it was more likely than not that circumstances would require us to sell the investment before recovery occurs; (viii) the underlying current and prospective asset and enterprise values of the issuer and the extent to which the recoverability of the carrying value of our investment would be affected by changes in such values; (ix) projections of, and unfavorable changes in, cash flows on structured securities including mortgage-backed and asset-backed securities; (x) our best estimate of the value of any collateral; and (xi) other objective and subjective factors.

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.

The following table summarizes the amount of credit losses recognized in earnings on fixed maturity securities, available for sale, held at the beginning of the period, for which a portion of the other-than-temporary impairment was also recognized in accumulated other comprehensive income for the three and nine months ended September 30, 2019 (dollars in millions):

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).

Segment Reporting [Abstract]  
BUSINESS SEGMENTS
BUSINESS SEGMENTS

Prior to 2020, the Company managed its business through the following operating segments: Bankers Life, Washington National and Colonial Penn, which were defined on the basis of product distribution; long-term care in run-off; and corporate operations, comprised of holding company activities and certain noninsurance company businesses.

In January 2020, we announced a new operating model that changes how we view our operating segments. Instead of the operating business segments described above, we view our operations as three insurance product lines (annuity, health and life) and the investment and fee revenue segments. The new structure creates a leaner, more integrated, customer-centric organization that better positions us for long-term success and shareholder value creation. Our new segments are aligned based on their common characteristics, comparability of profit margins and the way management makes operating decisions and assesses the performance of the business. We began reporting under the new segment structure in the first quarter of 2020. Prior period results have been reclassified to conform to the new reporting structure.

Our insurance product line segments (including annuity, health and life) include marketing, underwriting and administration of the policies our insurance subsidiaries sell. Under our new operating model, the business written in each of the three product categories through all of our insurance subsidiaries is aggregated allowing management and investors to assess the performance of each product category. When analyzing profitability of these segments, we use insurance product margin as the measure of profitability, which is: (i) insurance policy income; and (ii) net investment income allocated to the insurance product lines; less (i) insurance policy benefits and interest credited to policyholders; and (ii) amortization, non-deferred commissions and advertising expense. Net investment income is allocated to the product lines using the book yield of investments backing the block of business, which is applied to the average insurance liabilities, net of insurance intangibles, for the block in each period.

Income from insurance products is the sum of the insurance margins of the annuity, health and life product lines, less expenses allocated to the insurance lines. It excludes the income from our fee income business, investment income not allocated to product lines, net expenses not allocated to product lines (primarily holding company expenses) and income taxes.
Management believes insurance product margin and income from insurance products help provide a better understanding of the business and a more meaningful analysis of the results of our insurance product lines.

Under our new structure, we market our insurance products through the Consumer and Worksite Divisions that reflect the customers served by the Company.

The Consumer Division serves individual consumers, engaging with them on the phone, 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 and industry-leading direct-to-consumer business with proven experience in advertising, web/digital and call center support.

The Worksite Division focuses on worksite and group sales for businesses, associations, and other membership groups, interacting with customers at their place of employment. By creating a dedicated Worksite Division, we bring a sharper focus to this high-growth business while further capitalizing on the strength of our recent acquisition of Web Benefits Design Corporation ("WBD"). Sales in the Worksite Division have been particularly adversely impacted by the COVID-19 pandemic given the challenges of interacting with customers at their place of employment.

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. Sales of group underwritten policies are currently not significant, but are expected to increase within the Worksite Division.

We also centralized certain functional areas previously housed in the three business segments, including marketing, business unit finance, sales training and support, and agent recruiting, among others. All policy, contract, and certificate terms, conditions, and benefits remain unchanged.

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 and investment borrowings; and (iv) certain expenses related to benefit plans that are offset by special-purpose investment income. Investment income not allocated to product lines includes investment income on investments in excess of average insurance liabilities, investments held by our holding companies, the spread we earn from the Federal Home Loan Bank ("FHLB") investment borrowing program and variable components of investment income (including call and prepayment income, adjustments to returns on structured securities due to cash flow changes, income (loss) from company-owned life insurance ("COLI") and variations in income (loss) from alternative investments), net of interest expense on corporate debt.

Our fee and other revenue segment includes the earnings generated from sales of third-party insurance products, services provided by WBD (our wholly owned on-line benefit administration firm) and the operations of our broker-dealer and registered investment advisor.

Expenses not allocated to product lines include the expenses of our corporate operations, excluding interest expense on debt.

We measure segment performance by excluding net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), fair value changes related to the agent deferred compensation plan, loss on extinguishment of debt, income taxes and other non-operating items consisting primarily of earnings attributable to VIEs ("pre-tax operating earnings") because we believe that this performance measure is a better indicator of the ongoing business and trends in our business.  Our primary investment focus is on investment income to support our liabilities for insurance products as opposed to the generation of net realized investment gains (losses), and a long-term focus is necessary to maintain profitability over the life of the business.

The net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), fair value changes related to the agent deferred compensation plan, loss on extinguishment of debt 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.  Net realized investment gains (losses) and fair value changes in embedded derivative liabilities (net of related amortization) may affect future earnings levels since our underlying
business is long-term in nature and changes in our investment portfolio may impact our ability to earn the assumed interest rates needed to maintain the profitability of our business.

We are required to establish an embedded derivative related to a modified coinsurance agreement pursuant to which we assume the risks of a block of health insurance business. The embedded derivative represents the mark-to-market adjustment for approximately $113 million in underlying investments held by the ceding reinsurer at September 30, 2020.

Our fixed index annuity products provide a guaranteed minimum rate of return and a higher potential return 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.  Typically, on each policy anniversary date, a new index period begins.  We are generally able to change the participation rate at the beginning of each index period during a policy year, subject to contractual minimums.  The Company accounts for the options attributed to the policyholder for the estimated life of the contract as embedded derivatives. These accounting requirements often create volatility in the earnings from these products. We typically buy call options (including call spreads) referenced to the applicable indices in an effort to offset or hedge potential increases to policyholder benefits resulting from increases in the particular index to which the policy's return is linked.  The notional amount of these options were $2.7 billion and $3.2 billion at September 30, 2020 and December 31, 2019, respectively.

We purchase certain fixed maturity securities that contain embedded derivatives that are required to be held at fair value on the consolidated balance sheet. We have elected the fair value option to carry the entire security at fair value with changes in fair value recognized in net income.

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 can not be reliably estimated. In these cases, the actual tax expense or benefit applicable to that item is treated discretely and is reported in the same period as the related item. The components of income tax expense are as follows (dollars in millions):

The Tax Cuts and Job Act (the “Tax Reform Act”), which was effective in 2018, eliminated a company’s ability to carryback losses to prior years for losses realized in 2018 and beyond. In addition, the utilization of these net operating loss carryforwards ("NOLs") to offset income in 2018 and subsequent years was limited to 80 percent of taxable income. The Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, a tax-and-spending package intended to provide economic relief to address the impact of the COVID-19 pandemic, was signed into law in March 2020. Provisions in the CARES Act permit NOLs arising in a taxable year beginning after December 31, 2017, and before January 1, 2021 to be allowed as a carryback to each of the five taxable years preceding the taxable year of such loss. Accordingly, we are able to carryback the NOL created in 2018 related to the long-term care reinsurance transaction to 2017 and 2016 resulting in a $34.0 million tax benefit from the difference in tax rates between the current enacted rate of 21% and the enacted rate in 2016 and 2017 of 35%. This provision also accelerated the utilization of approximately $375 million of life NOLs and restored approximately $130 million of non-life NOLs. Further, the CARES Act temporarily repeals the 80 percent limitation for taxable years beginning
before January 1, 2021 (as required under the Tax Reform Act). This provision resulted in the acceleration of approximately $105 million of life NOLs and restored approximately $35 million of non-life NOLs.

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, shall be 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 including changes resulting from the Tax Reform Act, investment strategies, the impact of the sale or reinsurance of business, the recapture of business previously ceded, tax planning strategies and the COVID-19 pandemic. Our estimates of future taxable income are based on evidence we consider to be objectively verifiable. At September 30, 2020, our projection of future taxable income for purposes of determining the valuation allowance is based on our estimates of such future taxable income through the date our NOLs expire. Such estimates are subject to the risks and uncertainties associated with the COVID-19 pandemic and the extent to which actual impacts differ from the assumptions used in our deferred tax valuation model. Based on our assessment, we have concluded that it is more likely than not that all our deferred tax assets of $226.7 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 an increase in the valuation allowance in a future period.  Any future increase in the valuation allowance may result in additional income tax expense and reduce shareholders' equity, and such an increase could have a significant impact upon our earnings in the future.
The Internal Revenue Code (the "Code") limits the extent to which losses realized by a non-life entity (or entities) may offset income from a life insurance company (or companies) to the lesser of: (i) 35 percent of the income of the life insurance company; or (ii) 35 percent of the total loss of the non-life entities (including NOLs of the non-life entities). There is no similar limitation on the extent to which losses realized by a life insurance entity (or entities) may offset income from a non-life entity (or entities).

Section 382 of the Code imposes limitations on a corporation's ability to use its NOLs when the company undergoes a 50 percent ownership change over a three-year period.  Future transactions and the timing of such transactions could cause an ownership change for Section 382 income tax purposes.  Such transactions may include, but are not limited to, additional repurchases under our securities repurchase program, issuances of common stock and acquisitions or sales of shares of CNO stock by certain holders of our shares, including persons who have held, currently hold or may accumulate in the future five percent or more of our outstanding common stock for their own account.  Many of these transactions are beyond our control.  If an additional ownership change were to occur for purposes of Section 382, we would be required to calculate an annual restriction on the use of our NOLs to offset future taxable income.  The annual restriction would be calculated based upon the value of CNO's equity at the time of such ownership change, multiplied by a federal long-term tax exempt rate (.89 percent at September 30, 2020), and the annual restriction could limit our ability to use a substantial portion of our NOLs to offset future taxable income.  We regularly monitor ownership change (as calculated for purposes of Section 382) and, as of September 30, 2020, we were below the 50 percent ownership change level that could limit our ability to utilize our NOLs.

We have $1.8 billion of federal NOLs as of September 30, 2020, as summarized below (dollars in millions):

Total federal non-life NOLs$1,774.8 

Our life NOLs have been fully utilized in 2020. Our non-life NOLs can be used to offset 35 percent of remaining life insurance company taxable income until all non-life NOLs are utilized or expire.
We also had deferred tax assets related to NOLs for state income taxes of $4.5 million and $10.3 million at September 30, 2020 and December 31, 2019, respectively.  The related state NOLs are available to offset future state taxable income in certain states through 2033.
The federal statute of limitations remains open with respect to tax years 2016 through 2019. 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.

Revolving Credit Agreement

On May 19, 2015, the Company entered into a $150.0 million four-year unsecured revolving credit agreement with KeyBank National Association, as administrative agent (the "Agent"), and the lenders from time to time party thereto. On May 19, 2015, the Company made an initial drawing of $100.0 million under the Revolving Credit Agreement. On October 13, 2017, the Company entered into an amendment and restatement agreement (the "Amendment Agreement") with respect to its revolving credit agreement (as amended by the Amendment Agreement, the "Revolving Credit Agreement"). The Amendment Agreement, among other things, increased the total commitments available under the revolving credit facility from $150.0 million to $250.0 million, increased the aggregate amount of additional incremental loans the Company may incur from $50.0 million to $100.0 million and extended the maturity date of the revolving credit facility from May 19, 2019 to October 13, 2022. There were no amounts outstanding under the Revolving Credit Agreement during the nine months ended September 30, 2020.

The interest rates with respect to loans under the Revolving Credit Agreement are based on, at the Company's option, a floating base rate (defined as a per annum rate equal to the highest of: (i) the federal funds rate plus 0.50%; (ii) the "prime rate" of the Agent; and (iii) the eurodollar rate for a one-month interest period plus an applicable margin based on the Company's unsecured debt rating), or a eurodollar rate plus an applicable margin based on the Company's unsecured debt rating. The margins under the Revolving Credit Agreement range from 1.375 percent to 2.125 percent, in the case of loans at the eurodollar rate, and 0.375 percent to 1.125 percent, in the case of loans at the base rate. In addition, the daily average undrawn portion of the Revolving Credit Agreement accrues a commitment fee payable quarterly in arrears. The applicable margin for, and the commitment fee applicable to, the Revolving Credit Agreement, will be adjusted from time to time pursuant to a ratings-based pricing grid.

The Revolving Credit Agreement requires the Company to maintain (each as calculated in accordance with the Revolving Credit Agreement): (i) a debt to total capitalization ratio of not more than 35.0 percent (such ratio was 23.7 percent at September 30, 2020); (ii) an aggregate ratio of total adjusted capital to company action level risk-based capital for the Company's insurance subsidiaries of not less than 250 percent (such ratio was estimated to be 428 percent at September 30, 2020); and (iii) a minimum consolidated net worth of not less than the sum of (x) $2,674 million plus (y) 50.0 percent of the net equity proceeds received by the Company from the issuance and sale of equity interests in the Company (the Company's consolidated net worth was $3,282.3 million at September 30, 2020 compared to the minimum requirement of $2,693.4 million).

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, 2020, the carrying value of the FHLB common stock was $71.0 million.  As of September 30, 2020, collateralized borrowings from the FHLB totaled $1.6 billion and the proceeds were used to purchase fixed maturity securities.  The borrowings are classified as investment borrowings in the accompanying consolidated balance sheet.  The borrowings are collateralized by investments with an estimated fair value of $2.1 billion at September 30, 2020, which are maintained in a custodial account for the benefit of the FHLB.  Substantially all of such investments are classified as fixed maturities, available for sale, in our consolidated balance sheet.  
The following summarizes the terms of the borrowings from the FHLB by our insurance subsidiaries (dollars in millions):

The variable rate borrowings are pre-payable on each interest reset date without penalty.  The fixed rate borrowings are pre-payable subject to payment of a yield maintenance fee based on prevailing market interest rates.  At September 30, 2020, the aggregate yield maintenance fee to prepay all fixed rate borrowings was $5.2 million.

Interest expense of $18.3 million and $36.1 million in the first nine months of 2020 and 2019, respectively, was recognized related to total borrowings from the FHLB.

SALES INDUCEMENTS

Certain of our annuity products offer sales inducements to contract holders in the form of enhanced crediting rates or bonus payments in the initial period of the contract.  Certain of our life insurance products offer persistency bonuses credited to the contract holder's balance after the policy has been outstanding for a specified period of time.  These enhanced rates and persistency bonuses are considered sales inducements in accordance with GAAP.  Such amounts are deferred and amortized in the same manner as deferred acquisition costs.  Sales inducements deferred totaled $10.2 million and $21.2 million during the nine months ended September 30, 2020 and 2019, respectively.  Amounts amortized totaled $10.9 million and $3.8 million during the nine months ended September 30, 2020 and 2019, respectively.  The unamortized balance of deferred sales inducements was $60.0 million and $60.7 million at September 30, 2020 and December 31, 2019, respectively.

Accounting Changes and Error Corrections [Abstract]  
RECENTLY ISSUED ACCOUNTING STANDARDS
RECENTLY ISSUED ACCOUNTING STANDARDS

Pending Accounting Standards

In August 2018, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance that makes targeted improvements to the accounting for long-duration contracts. The new guidance: (i) improves the timeliness of recognizing changes in the liability for future benefits and modifies the rate used to discount future cash flows; (ii) simplifies and improves the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts; (iii) simplifies the amortization of deferred acquisition costs; and (iv) requires enhanced disclosures, including disaggregated rollforwards of the liability for future policy benefits, policyholder account liabilities, market risk benefits and deferred acquisition costs. Additionally, qualitative and quantitative information about expected cash flows, estimates and assumptions will be required. The new measurement guidance for traditional and limited-payment contract liabilities and the new guidance for the amortization of deferred acquisition costs are required to be adopted on a modified retrospective transition approach, with an option to elect a full retrospective transition if certain criteria are met. The transition approach for deferred acquisition costs is required to be consistent with the transition applied to the liability for future policyholder benefits. Under the modified retrospective approach, for contracts in-force at the transition date, an entity would continue to use the existing locked-in investment yield interest rate assumption to calculate the net premium ratio, rather than the upper-medium grade fixed-income corporate instrument yield. However, for balance sheet remeasurement purposes, the current upper-medium grade fixed-income corporate instrument yield would be used at transition through accumulated other comprehensive income and subsequently through other comprehensive income. For market risk benefits, retrospective application is required, with the ability to use hindsight to measure fair value components to the extent assumptions in a prior period are unobservable or otherwise unavailable. In October 2019, the FASB approved a delay for the effective date of the adoption of this guidance by one year (until January 1, 2022). In September 2020, the FASB voted to delay the effective date of this guidance for the Company by one year (until January 1, 2023). Final authoritative guidance addressing the revised effective date is expected to be issued later in 2020. The Company has not yet determined the expected impact of adoption of this guidance on its consolidated financial position, results of operations or cash flows.

Adopted Accounting Standards

In February 2016, the FASB issued authoritative guidance related to accounting for leases, requiring lessees to report most leases on their balance sheets, regardless of whether the lease is classified as a finance lease or an operating lease. For lessees, the initial lease liability is equal to the present value of future lease payments, and a corresponding asset, adjusted for certain items, is also recorded. Expense recognition for lessees will remain similar to current accounting requirements for capital and operating leases. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The guidance was effective for the Company on January 1, 2019. Based on lease
contracts in effect at January 1, 2019, the impact of implementation of the new leasing guidance was the recognition of a "right to use" asset (included in other assets) and a "lease liability" (included in other liabilities) of $72.0 million and there was no cumulative effect adjustment to retained earnings as of January 1, 2019. The Company elected to apply practical expedients related to the adoption of the new guidance including: not reassessing whether a contract includes an embedded lease at adoption; not reassessing the previously determined classification of a lease as operating or capital; not reassessing our previously recorded initial direct costs; election of an accounting policy that permits inclusion of both the lease and non-lease components as a single component and account for it as a lease; and election of an accounting policy to exclude lease accounting requirements for leases that have terms of less than twelve months. Refer to the note to the consolidated financial statements entitled "Leases" for additional disclosures.

In June 2016, the FASB issued authoritative guidance related to the measurement of credit losses on financial instruments. The new guidance replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Credit losses on available for sale debt securities are measured in a manner similar to current GAAP. However, the guidance requires that credit losses be presented as an allowance rather than as a writedown. The guidance was effective for the Company on January 1, 2020. The impact of adoption, using the modified retrospective approach, was as follows (dollars in millions):

Retained earnings535.7 (17.8)517.9 
Total shareholders' equity4,677.0 (17.8)4,659.2 
In March 2017, the FASB issued authoritative guidance related to the premium amortization on purchased callable debt securities. The guidance shortens the amortization period for certain callable debt securities held at a premium. Specifically, the new guidance requires the premium to be amortized to the earliest call date. The guidance does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance was effective for the Company on January 1, 2019. The guidance was applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of January 1, 2019. The impact of adoption was as follows (dollars in millions):
January 1, 2019
Amounts prior to effect of adoption of authoritative guidanceEffect of adoption of authoritative guidanceAs adjusted
Fixed maturities, available for sale$18,447.7 $(4.0)$18,443.7

Retained earnings196.6 (3.1)193.5 
Total shareholders' equity3,370.9 (3.1)3,367.8 
In January 2017, the FASB issued authoritative guidance that removes Step 2 of the goodwill impairment test under current guidance, which requires a hypothetical purchase price allocation. The new guidance requires an impairment charge to be recognized for the amount by which the carrying amount exceeds the reported unit's fair value. Upon adoption, the guidance is to be applied prospectively. The guidance was effective for the Company on January 1, 2020. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2017, the FASB issued authoritative guidance related to derivatives and hedging. The new guidance expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instruments and the hedged item in the financial statements. The new guidance also includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The guidance was effective for the Company on January 1, 2019. Based on the Company's current use of derivatives and hedging activities, the adoption of this guidance had no impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued authoritative guidance related to changes to the disclosure requirements for fair value measurement. The new guidance removes, modifies and adds certain disclosure requirements. The guidance was effective for the Company on January 1, 2020. The adoption of such guidance impacted certain fair value disclosures, but did not impact our consolidated financial position, results of operations or cash flows.

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 December 19, 2018, Melanie Cyganowski, as Equity Receiver for Platinum Partners Credit Opportunities Master Fund, LP ("PPCO") and other Platinum entities (the "PPCO Receiver") brought an action in the United States District Court for the Southern District of New York, Cyganowski v. Beechwood Re Ltd, et al., alleging, among other claims, fraud, aiding and abetting fraud, fraudulent transfer and violation of the Racketeer Influenced and Corrupt Organizations Act against numerous defendants, including Beechwood Re Ltd. ("BRe") and many of its affiliates and CNO Financial Group, Inc., Bankers Conseco Life Insurance Company ("BCLIC"), Washington National and 40|86 Advisors, Inc. (collectively, the "CNO Parties"). The PPCO Receiver alleged that Platinum insiders conspired with BRe and its principals and affiliates in a massive fraudulent scheme to enrich the Platinum and BRe insiders to the detriment of Platinum investors and creditors. The PPCO Receiver alleged that CNO Financial Group, Inc., BCLIC, Washington National and 40|86 Advisors, Inc. had liability for the fraudulent scheme of the Platinum and BRe insiders under a theory that they turned a blind eye to the fraudulent scheme due to their desire to transfer unprofitable legacy portfolios of long-term care insurance via the reinsurance transactions with BRe. On January 24, 2019, the court consolidated the PPCO Receiver action with two other cases (to which the CNO companies are not parties) before it for at least discovery purposes.  On August 19, 2019, the court granted in their entirety CNO Financial Group, Inc.’s and 40|86 Advisors, Inc.’s motions to dismiss the PPCO Receiver’s claims against them. The court granted in part and denied in part the motions to dismiss of BCLIC and Washington National, dismissing the PPCO Receiver’s claims for, among other things, fraud, aiding and abetting fraud, securities fraud and violation of the Racketeer Influenced and Corrupt Organizations Act, while denying BCLIC’s and Washington National’s motions to dismiss the PPCO Receiver’s fraudulent transfer and unjust enrichment claims. BCLIC and Washington National agreed with the PPCO Receiver to fully settle the Cyganowski case. Under the settlement, neither BCLIC nor Washington National will incur any liability or make any payment to anyone, but instead they were granted an unsecured claim against PPCO’s estate. The settlement agreement states that the PPCO Receiver’s decision to enter into the agreement was based in part on the CNO Parties’ credible arguments based on an expansive documentary record that the CNO Parties were not knowing participants in any fraud perpetrated by any of the Platinum funds or any of the Beechwood entities, but were instead purely victims of such fraud schemes. The settlement agreement was approved by the Court on July 17, 2020, and the Joint Stipulation and Order of Dismissal with Prejudice was accepted by the Court on August 6, 2020. The Cyganowski case is thus completely concluded.

On April 9, 2019, BCLIC and Washington National commenced an action entitled Bankers Conseco Life Insurance Company and Washington National Insurance Company v. Wilmington Trust, National Association, in the Supreme Court of the State of New York, County of New York, Commercial Division (the "Wilmington Action").  In the Wilmington Action, BCLIC and Washington National assert claims against Wilmington Trust, National Association ("Wilmington") for breaching its express contractual obligations under four trust agreements pursuant to which Wilmington was the trustee in regard to trust assets ceded as part of reinsurance agreements with BRe, as well as for breaching its fiduciary duties to BCLIC and Washington National. The Court granted Wilmington’s motion to dismiss this litigation. BCLIC and Washington National are appealing the Court’s decision.

On June 7, 2019, the Joint Official Liquidators of Platinum Partners Value Arbitrage Fund L.P. (in Official Liquidation) and Principal Growth Strategies, LLC, commenced suit against, among others, the CNO Parties in Delaware Chancery Court. 
Plaintiffs allege that the CNO Parties were unjustly enriched when they terminated BCLIC and Washington National's reinsurance agreements with BRe and recaptured assets from reinsurance trusts, in particular, Agera securities.  Plaintiffs contend that the Agera securities were fraudulently transferred to the Reinsurance Trusts by other Platinum-related entities and they are seeking to claw back those Agera securities, or the value of those assets, from the CNO Parties.  The CNO Parties are vigorously contesting the plaintiff’s claims. The CNO Parties had removed the case to the United States District Court for the District of Delaware but on April 6, 2020, the District Court granted the plaintiff's motion to remand the case back to the Delaware Chancery Court. The Plaintiff has filed an Amended Complaint and the CNO Parties have responded.

On June 28, 2019, BCLIC and Washington National commenced an action entitled Bankers Conseco Life Insurance Company and Washington National Insurance Company v. KPMG LLP, in the Supreme Court of the State of New York, County of New York, Commercial Division (the "KPMG Action").  In the KPMG Action, BCLIC and Washington National assert claims against KPMG LLP ("KPMG") for aiding and abetting fraud, constructive fraud and negligent misrepresentation arising from KPMG's alleged role in the Platinum Partners' scheme to defraud BCLIC and Washington National into reinsuring its long-term care business with BRe. The Court granted KPMG’s motion to dismiss this litigation. BCLIC and Washington
National are appealing the Court’s decision.

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.

In August 2011, we were notified of an examination to be done on behalf of a number of states for the purpose of determining compliance with unclaimed property laws by the Company and its subsidiaries.  Such examination has included inquiries related to the use of data available on the U.S. Social Security Administration's Death Master File ("SSADMF") to identify instances where benefits under life insurance policies, annuities and retained asset accounts are payable. We are continuing to provide information to the examiners in response to their requests. A total of 41 states and the District of Columbia participated in this examination. In November 2018, we entered into a Global Resolution Agreement for compliance with laws and regulations concerning the identification, reporting and escheatment of unclaimed contract benefits or abandoned funds. Under the terms of the Global Resolution Agreement, a third-party auditor acting on behalf of the signatory jurisdictions is comparing expanded matching criteria to the SSADMF to identify deceased insureds and contract holders where a valid claim has not been made.

INVESTMENTS IN VARIABLE INTEREST ENTITIES

We have concluded that we are the primary beneficiary with respect to certain VIEs, which are consolidated in our financial statements.  In consolidating the VIEs, we consistently use the financial information most recently distributed to investors in the VIE.

All of the VIEs are collateralized loan trusts that were established to issue securities to finance the purchase of corporate loans and other permitted investments.  The assets held by the trusts are legally isolated and not available to the Company.  The liabilities of the VIEs are expected to be satisfied from the cash flows generated by the underlying loans held by the trusts, not from the assets of the Company.  The Company has no financial obligation to the VIEs beyond its investment in each VIE.

Certain of our subsidiaries are noteholders of the VIEs.  Another subsidiary of the Company is the investment manager for the VIEs.  As such, it has the power to direct the most significant activities of the VIEs which materially impacts the economic performance of the VIEs.

The following tables provide supplemental information about the assets and liabilities of the VIEs which have been consolidated in accordance with authoritative guidance (dollars in millions):

During the first nine months of 2020, the VIEs recognized net realized investment losses of $17.9 million which were comprised of: (i) $5.6 million of net losses from the sales of fixed maturities; and (ii) a $12.3 million increase in the allowance for credit losses. Such net realized losses included gross realized losses of $5.7 million from the sale of $47.3 million of investments. During the first nine months of 2019, the VIEs recognized net realized investment losses of $15.8 million which were comprised of: (i) $10.7 million of net losses from the sales of fixed maturities; and (ii) $5.1 million of losses on the dissolution of a VIE. Such net realized losses included gross realized losses of $10.9 million from the sale of $276.8 million of investments.

At September 30, 2020, there were six investments held by the VIEs in default with an amortized cost of $11.4 million, a carrying value of $6.2 million and an allowance for credit losses of $5.0 million.

At September 30, 2020, the VIEs held: (i) investments with a fair value of $643.0 million and gross unrealized losses not deemed to have credit losses of $14.3 million that had been in an unrealized loss position for less than twelve months; and (ii) investments with a fair value of $196.4 million and gross unrealized losses not deemed to have credit losses of $7.4 million that had been in an unrealized loss position for twelve months or greater.

At December 31, 2019, the VIEs held: (i) investments with a fair value of $153.0 million and gross unrealized losses of $3.1 million that had been in an unrealized loss position for less than twelve months; and (ii) investments with a fair value of $430.1 million and gross unrealized losses of $18.5 million that had been in an unrealized loss position for twelve months or greater.
The investments held by the VIEs are evaluated for impairment in a manner that is consistent with the Company's fixed maturities, available for sale. Similarly, prior to January 1, 2020, the investments held by the VIEs were evaluated for other-than-temporary declines in fair value in a manner that was 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, 2020, we held investments in various limited partnerships, in which we are not the primary beneficiary, totaling $557.1 million (classified as other invested assets).  At September 30, 2020, we had unfunded commitments to these partnerships totaling $78.8 million.  Our maximum exposure to loss on these investments is limited to the amount of our investment.

Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, therefore, represents an exit price, not an entry price.  We carry certain assets and liabilities at fair value on a recurring basis, including fixed maturities, equity securities, trading securities, investments held by VIEs, derivatives, separate account assets and embedded derivatives.  We carry our COLI, which is invested in a series of mutual funds, at its cash surrender value which approximates fair value. In addition, we disclose fair value for certain financial instruments, including mortgage loans, policy loans, cash and cash equivalents, insurance liabilities for interest-sensitive products, investment borrowings, notes payable and borrowings related to VIEs.

The degree of judgment utilized in measuring the fair value of financial instruments is largely dependent on the level to which pricing is based on observable inputs.  Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our view of market assumptions in the absence of observable market information. Financial instruments with readily available active quoted prices would be considered to have fair values based on the highest level of observable inputs, and little judgment would be utilized in measuring fair value.  Financial instruments that rarely trade would often have fair value based on a lower level of observable inputs, and more judgment would be utilized in measuring fair value.

Valuation Hierarchy

There is a three-level hierarchy for valuing assets or liabilities at fair value based on whether inputs are observable or unobservable.

•Level 1 – includes assets and liabilities valued using inputs that are unadjusted quoted prices in active markets for identical assets or liabilities.  Our Level 1 assets primarily include cash and cash equivalents and exchange-traded securities.

•Level 2 – includes assets and liabilities valued using inputs that are quoted prices for similar assets in an active market, quoted prices for identical or similar assets in a market that is not active, observable inputs, or observable inputs that can be corroborated by market data.  Level 2 assets and liabilities include those financial instruments that are valued by independent pricing services using models or other valuation methodologies.  These models consider various inputs such as credit rating, maturity, corporate credit spreads, reported trades and other inputs that are observable or derived from observable information in the marketplace or are supported by transactions executed in the marketplace. Financial assets in this category primarily include: certain publicly registered and privately placed corporate fixed maturity securities; certain government or agency securities; certain mortgage and asset-backed securities; certain equity securities; most investments held by our consolidated VIEs; and derivatives such as call options. Financial liabilities in this category include investment borrowings, notes payable and borrowings related to VIEs.

•Level 3 – includes assets and liabilities valued using unobservable inputs that are used in model-based valuations that contain management assumptions.  Level 3 assets and liabilities include those financial instruments whose fair value is estimated based on broker/dealer quotes, pricing services or internally developed models or methodologies utilizing significant inputs not based on, or corroborated by, readily available market information.  Financial assets in this category include certain corporate securities, certain structured securities, mortgage loans, and other less liquid securities.  Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives (including embedded derivatives related to our fixed index annuity products and to a modified coinsurance arrangement) 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 fixed maturity and equity securities, including those held in trading portfolios and those held by consolidated VIEs and separate account assets 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. 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. 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. 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, commercial mortgage-backed securities and collateralized loan obligations are generally priced using market and income approaches. Inputs generally consist of quoted prices in inactive markets, spreads on actively traded securities, expected prepayments, expected default rates, expected recovery rates and issue specific information including, but not limited to, collateral type, seniority and vintage.

Equity securities are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads.

•Investments held by VIEs

Corporate securities are generally priced using market and income approaches using pricing vendors. Inputs generally consist of issuer rating, benchmark yields, maturity, and credit spreads.

•Other invested assets - derivatives

The fair value measurements for derivative instruments, including embedded derivatives requiring bifurcation, are determined based on the consideration of several inputs including closing exchange or over-the-counter market price quotes, time value and volatility factors underlying options, market interest rates and non-performance risk.

Third-party pricing services normally derive security prices through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information.  If there are no recently reported trades, the third-party pricing services may use matrix or model processes to develop a security price where future cash flow expectations are discounted at an estimated risk-adjusted market rate.  The number of prices obtained for a given security is dependent on the Company's analysis of such prices as further described below.

As the Company is responsible for the determination of fair value, we have control processes designed to ensure that the fair values received from third-party pricing sources are reasonable and the valuation techniques and assumptions used appear reasonable and consistent with prevailing market conditions. Additionally, when inputs are provided by third-party pricing sources, we have controls in place to review those inputs for reasonableness. As part of these controls, we perform
monthly quantitative and qualitative analysis on the prices received from third parties to determine whether the prices are reasonable estimates of fair value.  The Company's analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) where available, a comparison of multiple pricing services' valuations for the same security; (iii) a review of month to month price fluctuations; (iv) a review to ensure valuations are not unreasonably dated; and (v) back testing to compare actual purchase and sale transactions with valuations received from third parties.  As a result of such procedures, the Company may conclude a particular price received from a third party is not reflective of current market conditions.  In those instances, we may request additional pricing quotes or apply internally developed valuations. However, the number of such instances is insignificant and the aggregate change in value of such investments is not materially different from the original prices received.

The categorization of the fair value measurements of our investments priced by independent pricing services was based upon the Company's judgment of the inputs or methodologies used by the independent pricing services to value different asset classes.  Such inputs typically include: benchmark yields, reported trades, broker dealer quotes, issuer spreads, benchmark securities, bids, offers and other relevant data.  The Company categorizes such fair value measurements based upon asset classes and the underlying observable or unobservable inputs used to value such investments.

For securities that are not priced by pricing services and may not be reliably priced using pricing models, we obtain broker quotes.  These broker quotes are non-binding and represent an exit price, but assumptions used to establish the fair value may not be observable and therefore represent Level 3 inputs.  Approximately 88 percent of our Level 3 fixed maturity 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 pricing service information for certain assets that the Company is able to validate.
(b)Purchases, sales, issuances and settlements, net, represent the activity that occurred during the period that results in a change of the asset or liability 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 and changes to embedded derivative instruments related to insurance products resulting from the issuance of new contracts, or changes to existing contracts.  The following summarizes such activity for the nine months ended September 30, 2019 (dollars in millions):

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, net realized investment gains (losses) or insurance policy benefits within the consolidated statement of operations or accumulated other comprehensive income 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 and liabilities still held as of the reporting date primarily represents impairments for fixed maturities, available for sale, changes in fair value of trading securities and certain derivatives and changes in fair value of embedded derivative instruments included in liabilities for insurance products that exist as of the reporting date.

The amount presented for gains (losses) included in accumulated other comprehensive income (loss) for assets and liabilities still 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, 2020, 92 percent of our Level 3 fixed maturities, available for sale, were investment grade and 87 percent of our Level 3 fixed maturities, available for sale, consisted of corporate securities.

BUSINESS AND BASIS OF PRESENTATION (Policies)
 9 Months Ended

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), other-than-temporary impairments of investments, assets and liabilities related to income taxes, liabilities for insurance products, liabilities related to litigation and guaranty fund assessment accruals.  If our future experience differs from these estimates and assumptions, our financial statements could be materially affected.
Consolidation The accompanying financial statements 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.
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 tax and related adjustments, 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 realized investment gains (losses)).
Prior to January 1, 2020, we regularly evaluated all of our investments with unrealized losses for possible impairment.  Our assessment of whether unrealized losses were "other than temporary" required significant judgment.  Factors considered included: (i) the extent to which fair value was less than the cost basis; (ii) the length of time that the fair value had been less than cost; (iii) whether the unrealized loss was event driven, credit-driven or a result of changes in market interest rates or risk premium; (iv) the near-term prospects for specific events, developments or circumstances likely to affect the value of the investment; (v) the investment's rating and whether the investment was investment-grade and/or had been downgraded since its purchase; (vi) whether the issuer was current on all payments in accordance with the contractual terms of the investment and was expected to meet all of its obligations under the terms of the investment; (vii) whether we intended to sell the investment or it was more likely than not that circumstances would require us to sell the investment before recovery occurs; (viii) the underlying current and prospective asset and enterprise values of the issuer and the extent to which the recoverability of the carrying value of our investment would be affected by changes in such values; (ix) projections of, and unfavorable changes in, cash flows on structured securities including mortgage-backed and asset-backed securities; (x) our best estimate of the value of any collateral; and (xi) other objective and subjective factors.

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
Prior to 2020, the Company managed its business through the following operating segments: Bankers Life, Washington National and Colonial Penn, which were defined on the basis of product distribution; long-term care in run-off; and corporate operations, comprised of holding company activities and certain noninsurance company businesses.

In January 2020, we announced a new operating model that changes how we view our operating segments. Instead of the operating business segments described above, we view our operations as three insurance product lines (annuity, health and life) and the investment and fee revenue segments. The new structure creates a leaner, more integrated, customer-centric organization that better positions us for long-term success and shareholder value creation. Our new segments are aligned based on their common characteristics, comparability of profit margins and the way management makes operating decisions and assesses the performance of the business. We began reporting under the new segment structure in the first quarter of 2020. Prior period results have been reclassified to conform to the new reporting structure.

Our insurance product line segments (including annuity, health and life) include marketing, underwriting and administration of the policies our insurance subsidiaries sell. Under our new operating model, the business written in each of the three product categories through all of our insurance subsidiaries is aggregated allowing management and investors to assess the performance of each product category. When analyzing profitability of these segments, we use insurance product margin as the measure of profitability, which is: (i) insurance policy income; and (ii) net investment income allocated to the insurance product lines; less (i) insurance policy benefits and interest credited to policyholders; and (ii) amortization, non-deferred commissions and advertising expense. Net investment income is allocated to the product lines using the book yield of investments backing the block of business, which is applied to the average insurance liabilities, net of insurance intangibles, for the block in each period.

Income from insurance products is the sum of the insurance margins of the annuity, health and life product lines, less expenses allocated to the insurance lines. It excludes the income from our fee income business, investment income not allocated to product lines, net expenses not allocated to product lines (primarily holding company expenses) and income taxes.
Management believes insurance product margin and income from insurance products help provide a better understanding of the business and a more meaningful analysis of the results of our insurance product lines.

Under our new structure, we market our insurance products through the Consumer and Worksite Divisions that reflect the customers served by the Company.

The Consumer Division serves individual consumers, engaging with them on the phone, 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 and industry-leading direct-to-consumer business with proven experience in advertising, web/digital and call center support.

The Worksite Division focuses on worksite and group sales for businesses, associations, and other membership groups, interacting with customers at their place of employment. By creating a dedicated Worksite Division, we bring a sharper focus to this high-growth business while further capitalizing on the strength of our recent acquisition of Web Benefits Design Corporation ("WBD"). Sales in the Worksite Division have been particularly adversely impacted by the COVID-19 pandemic given the challenges of interacting with customers at their place of employment.

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. Sales of group underwritten policies are currently not significant, but are expected to increase within the Worksite Division.

We also centralized certain functional areas previously housed in the three business segments, including marketing, business unit finance, sales training and support, and agent recruiting, among others. All policy, contract, and certificate terms, conditions, and benefits remain unchanged.

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 and investment borrowings; and (iv) certain expenses related to benefit plans that are offset by special-purpose investment income. Investment income not allocated to product lines includes investment income on investments in excess of average insurance liabilities, investments held by our holding companies, the spread we earn from the Federal Home Loan Bank ("FHLB") investment borrowing program and variable components of investment income (including call and prepayment income, adjustments to returns on structured securities due to cash flow changes, income (loss) from company-owned life insurance ("COLI") and variations in income (loss) from alternative investments), net of interest expense on corporate debt.

Our fee and other revenue segment includes the earnings generated from sales of third-party insurance products, services provided by WBD (our wholly owned on-line benefit administration firm) and the operations of our broker-dealer and registered investment advisor.

Expenses not allocated to product lines include the expenses of our corporate operations, excluding interest expense on debt.

We measure segment performance by excluding net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), fair value changes related to the agent deferred compensation plan, loss on extinguishment of debt, income taxes and other non-operating items consisting primarily of earnings attributable to VIEs ("pre-tax operating earnings") because we believe that this performance measure is a better indicator of the ongoing business and trends in our business.  Our primary investment focus is on investment income to support our liabilities for insurance products as opposed to the generation of net realized investment gains (losses), and a long-term focus is necessary to maintain profitability over the life of the business.

The net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), fair value changes related to the agent deferred compensation plan, loss on extinguishment of debt 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.  Net realized investment gains (losses) and fair value changes in embedded derivative liabilities (net of related amortization) 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.
Pending Accounting Standards and Adopted Accounting Standards
Pending Accounting Standards

In August 2018, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance that makes targeted improvements to the accounting for long-duration contracts. The new guidance: (i) improves the timeliness of recognizing changes in the liability for future benefits and modifies the rate used to discount future cash flows; (ii) simplifies and improves the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts; (iii) simplifies the amortization of deferred acquisition costs; and (iv) requires enhanced disclosures, including disaggregated rollforwards of the liability for future policy benefits, policyholder account liabilities, market risk benefits and deferred acquisition costs. Additionally, qualitative and quantitative information about expected cash flows, estimates and assumptions will be required. The new measurement guidance for traditional and limited-payment contract liabilities and the new guidance for the amortization of deferred acquisition costs are required to be adopted on a modified retrospective transition approach, with an option to elect a full retrospective transition if certain criteria are met. The transition approach for deferred acquisition costs is required to be consistent with the transition applied to the liability for future policyholder benefits. Under the modified retrospective approach, for contracts in-force at the transition date, an entity would continue to use the existing locked-in investment yield interest rate assumption to calculate the net premium ratio, rather than the upper-medium grade fixed-income corporate instrument yield. However, for balance sheet remeasurement purposes, the current upper-medium grade fixed-income corporate instrument yield would be used at transition through accumulated other comprehensive income and subsequently through other comprehensive income. For market risk benefits, retrospective application is required, with the ability to use hindsight to measure fair value components to the extent assumptions in a prior period are unobservable or otherwise unavailable. In October 2019, the FASB approved a delay for the effective date of the adoption of this guidance by one year (until January 1, 2022). In September 2020, the FASB voted to delay the effective date of this guidance for the Company by one year (until January 1, 2023). Final authoritative guidance addressing the revised effective date is expected to be issued later in 2020. The Company has not yet determined the expected impact of adoption of this guidance on its consolidated financial position, results of operations or cash flows.

Adopted Accounting Standards

In February 2016, the FASB issued authoritative guidance related to accounting for leases, requiring lessees to report most leases on their balance sheets, regardless of whether the lease is classified as a finance lease or an operating lease. For lessees, the initial lease liability is equal to the present value of future lease payments, and a corresponding asset, adjusted for certain items, is also recorded. Expense recognition for lessees will remain similar to current accounting requirements for capital and operating leases. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The guidance was effective for the Company on January 1, 2019. Based on lease
contracts in effect at January 1, 2019, the impact of implementation of the new leasing guidance was the recognition of a "right to use" asset (included in other assets) and a "lease liability" (included in other liabilities) of $72.0 million and there was no cumulative effect adjustment to retained earnings as of January 1, 2019. The Company elected to apply practical expedients related to the adoption of the new guidance including: not reassessing whether a contract includes an embedded lease at adoption; not reassessing the previously determined classification of a lease as operating or capital; not reassessing our previously recorded initial direct costs; election of an accounting policy that permits inclusion of both the lease and non-lease components as a single component and account for it as a lease; and election of an accounting policy to exclude lease accounting requirements for leases that have terms of less than twelve months. Refer to the note to the consolidated financial statements entitled "Leases" for additional disclosures.

In June 2016, the FASB issued authoritative guidance related to the measurement of credit losses on financial instruments. The new guidance replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Credit losses on available for sale debt securities are measured in a manner similar to current GAAP. However, the guidance requires that credit losses be presented as an allowance rather than as a writedown. The guidance was effective for the Company on January 1, 2020. The impact of adoption, using the modified retrospective approach, was as follows (dollars in millions):

Total shareholders' equity4,677.0 (17.8)4,659.2 
In March 2017, the FASB issued authoritative guidance related to the premium amortization on purchased callable debt securities. The guidance shortens the amortization period for certain callable debt securities held at a premium. Specifically, the new guidance requires the premium to be amortized to the earliest call date. The guidance does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance was effective for the Company on January 1, 2019. The guidance was applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of January 1, 2019. The impact of adoption was as follows (dollars in millions):
January 1, 2019

Retained earnings196.6 (3.1)193.5 
Total shareholders' equity3,370.9 (3.1)3,367.8 
In January 2017, the FASB issued authoritative guidance that removes Step 2 of the goodwill impairment test under current guidance, which requires a hypothetical purchase price allocation. The new guidance requires an impairment charge to be recognized for the amount by which the carrying amount exceeds the reported unit's fair value. Upon adoption, the guidance is to be applied prospectively. The guidance was effective for the Company on January 1, 2020. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2017, the FASB issued authoritative guidance related to derivatives and hedging. The new guidance expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instruments and the hedged item in the financial statements. The new guidance also includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The guidance was effective for the Company on January 1, 2019. Based on the Company's current use of derivatives and hedging activities, the adoption of this guidance had no impact on the Company's consolidated financial position, results of operations or cash flows.

In August 2018, the FASB issued authoritative guidance related to changes to the disclosure requirements for fair value measurement. The new guidance removes, modifies and adds certain disclosure requirements. The guidance was effective for the Company on January 1, 2020. The adoption of such guidance impacted certain fair value disclosures, but did not impact our consolidated financial position, results of operations or cash flows.
Fair Value Measurements
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and, therefore, represents an exit price, not an entry price.  We carry certain assets and liabilities at fair value on a recurring basis, including fixed maturities, equity securities, trading securities, investments held by VIEs, derivatives, separate account assets and embedded derivatives.  We carry our COLI, which is invested in a series of mutual funds, at its cash surrender value which approximates fair value. In addition, we disclose fair value for certain financial instruments, including mortgage loans, policy loans, cash and cash equivalents, insurance liabilities for interest-sensitive products, investment borrowings, notes payable and borrowings related to VIEs.

The degree of judgment utilized in measuring the fair value of financial instruments is largely dependent on the level to which pricing is based on observable inputs.  Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our view of market assumptions in the absence of observable market information. Financial instruments with readily available active quoted prices would be considered to have fair values based on the highest level of observable inputs, and little judgment would be utilized in measuring fair value.  Financial instruments that rarely trade would often have fair value based on a lower level of observable inputs, and more judgment would be utilized in measuring fair value.

Valuation Hierarchy

There is a three-level hierarchy for valuing assets or liabilities at fair value based on whether inputs are observable or unobservable.

•Level 1 – includes assets and liabilities valued using inputs that are unadjusted quoted prices in active markets for identical assets or liabilities.  Our Level 1 assets primarily include cash and cash equivalents and exchange-traded securities.

•Level 2 – includes assets and liabilities valued using inputs that are quoted prices for similar assets in an active market, quoted prices for identical or similar assets in a market that is not active, observable inputs, or observable inputs that can be corroborated by market data.  Level 2 assets and liabilities include those financial instruments that are valued by independent pricing services using models or other valuation methodologies.  These models consider various inputs such as credit rating, maturity, corporate credit spreads, reported trades and other inputs that are observable or derived from observable information in the marketplace or are supported by transactions executed in the marketplace. Financial assets in this category primarily include: certain publicly registered and privately placed corporate fixed maturity securities; certain government or agency securities; certain mortgage and asset-backed securities; certain equity securities; most investments held by our consolidated VIEs; and derivatives such as call options. Financial liabilities in this category include investment borrowings, notes payable and borrowings related to VIEs.

•Level 3 – includes assets and liabilities valued using unobservable inputs that are used in model-based valuations that contain management assumptions.  Level 3 assets and liabilities include those financial instruments whose fair value is estimated based on broker/dealer quotes, pricing services or internally developed models or methodologies utilizing significant inputs not based on, or corroborated by, readily available market information.  Financial assets in this category include certain corporate securities, certain structured securities, mortgage loans, and other less liquid securities.  Financial liabilities in this category include our insurance liabilities for interest-sensitive products, which includes embedded derivatives (including embedded derivatives related to our fixed index annuity products and to a modified coinsurance arrangement) 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 fixed maturity and equity securities, including those held in trading portfolios and those held by consolidated VIEs and separate account assets 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. 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. 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. 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, commercial mortgage-backed securities and collateralized loan obligations are generally priced using market and income approaches. Inputs generally consist of quoted prices in inactive markets, spreads on actively traded securities, expected prepayments, expected default rates, expected recovery rates and issue specific information including, but not limited to, collateral type, seniority and vintage.

Equity securities are generally priced using the market approach. Inputs generally consist of trades of identical or similar securities, quoted prices in inactive markets, issuer rating, benchmark yields, maturity and credit spreads.

•Investments held by VIEs

Corporate securities are generally priced using market and income approaches using pricing vendors. Inputs generally consist of issuer rating, benchmark yields, maturity, and credit spreads.

•Other invested assets - derivatives

The fair value measurements for derivative instruments, including embedded derivatives requiring bifurcation, are determined based on the consideration of several inputs including closing exchange or over-the-counter market price quotes, time value and volatility factors underlying options, market interest rates and non-performance risk.

Third-party pricing services normally derive security prices through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information.  If there are no recently reported trades, the third-party pricing services may use matrix or model processes to develop a security price where future cash flow expectations are discounted at an estimated risk-adjusted market rate.  The number of prices obtained for a given security is dependent on the Company's analysis of such prices as further described below.

As the Company is responsible for the determination of fair value, we have control processes designed to ensure that the fair values received from third-party pricing sources are reasonable and the valuation techniques and assumptions used appear reasonable and consistent with prevailing market conditions. Additionally, when inputs are provided by third-party pricing sources, we have controls in place to review those inputs for reasonableness. As part of these controls, we perform
monthly quantitative and qualitative analysis on the prices received from third parties to determine whether the prices are reasonable estimates of fair value.  The Company's analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) where available, a comparison of multiple pricing services' valuations for the same security; (iii) a review of month to month price fluctuations; (iv) a review to ensure valuations are not unreasonably dated; and (v) back testing to compare actual purchase and sale transactions with valuations received from third parties.  As a result of such procedures, the Company may conclude a particular price received from a third party is not reflective of current market conditions.  In those instances, we may request additional pricing quotes or apply internally developed valuations. However, the number of such instances is insignificant and the aggregate change in value of such investments is not materially different from the original prices received.

The categorization of the fair value measurements of our investments priced by independent pricing services was based upon the Company's judgment of the inputs or methodologies used by the independent pricing services to value different asset classes.  Such inputs typically include: benchmark yields, reported trades, broker dealer quotes, issuer spreads, benchmark securities, bids, offers and other relevant data.  The Company categorizes such fair value measurements based upon asset classes and the underlying observable or unobservable inputs used to value such investments.

For securities that are not priced by pricing services and may not be reliably priced using pricing models, we obtain broker quotes.  These broker quotes are non-binding and represent an exit price, but assumptions used to establish the fair value may not be observable and therefore represent Level 3 inputs.  Approximately 88 percent of our Level 3 fixed maturity 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)    The weighted average is based on the relative fair value of the related assets or liabilities.
(b)    Corporate securities - The significant unobservable input used in the fair value measurement of our corporate 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 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.
(d)    Equity securities - The significant unobservable input used in the fair value measurement of these equity 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.
(e)    Other assets categorized as Level 3 - For these assets, there were no adjustments to quoted market prices obtained from third-party pricing sources.
(f)    Embedded derivatives related to fixed index annuity products (classified as policyholder account liabilities) - The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed index annuity products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would have led to a higher (lower) fair value measurement. The discount rate is based on risk free rates (U.S. Treasury rates for similar durations) adjusted for our non-performance risk and risk margins for non-capital market inputs. Increases (decreases) in the discount rates would have led to a lower (higher) fair value measurement. Assumed surrender rates are used to project how long the contracts remain in force. Generally, the longer the contracts are assumed to be in force the higher the fair value of the embedded derivative.
