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 2012 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.  CNO became the successor to Conseco, Inc., an Indiana corporation (our "Predecessor"), in connection with our bankruptcy reorganization which became effective on September 10, 2003.  The terms "CNO Financial Group, Inc.", the "Company", "we", "us", and "our" as used in these financial statements refer to CNO and its subsidiaries or, when the context requires otherwise, our Predecessor 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 the pre-retiree and retired middle-income American markets, 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 2013 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.

The balance sheet at December 31, 2012, 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 would 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.
OUT-OF-PERIOD ADJUSTMENT (Notes)
OUT-OF-PERIOD ADJUSTMENT
OUT-OF-PERIOD ADJUSTMENT

We recorded the net effect of an out-of-period adjustment which increased our insurance policy benefits by $6.7 million, increased amortization expense by $2.5 million, decreased tax expense by $3.2 million and decreased our net income by $6.0 million (or 3 cents per diluted share) in the six months ended June 30, 2013 (none of which was recognized in the second quarter of 2013). We evaluated this error taking into account both qualitative and quantitative factors and considered the impact of this error in relation to the 2013 period, as well as the materiality to the periods in which they originated. The impact of correcting this error in prior years was not significant to any individual period. Management believes this error is immaterial to the consolidated financial statements and all previously issued financial statements.
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 net investment income (classified as investment income from policyholder and reinsurer accounts and other special-purpose portfolios)).

Our trading securities include: (i) investments purchased with the intent of selling in the near term to generate income on price changes; and (ii) investments supporting certain insurance liabilities (including investments backing the market strategies of our multibucket annuity products) and certain reinsurance agreements. The change in fair value of these securities is recognized in income from policyholder and reinsurer accounts and other special-purpose portfolios (a component of net investment income). Investment income from trading securities backing certain insurance liabilities and certain reinsurance agreements is substantially offset by the change in insurance policy benefits related to certain products and agreements.  The trading account also includes certain fixed maturity securities containing embedded derivatives for which we have elected the fair value option. The change in value of these securities is recognized in realized investment gains (losses). Our trading securities totaled $241.0 million and $266.2 million at June 30, 2013 and December 31, 2012, respectively.

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 June 30, 2013 and December 31, 2012, 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 our Predecessor emerged from bankruptcy).

At June 30, 2013, adjustments to the present value of future profits, deferred acquisition costs, insurance liabilities and deferred tax assets included $(151.4) million, $(146.8) million, $(25.8) million and $116.6 million, respectively, for premium deficiencies that would exist on certain long-term health products 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 June 30, 2013, the amortized cost, gross unrealized gains and losses, estimated fair value, other-than-temporary impairments in accumulated other comprehensive income of fixed maturities, available for sale, were as follows (dollars in millions):

The following table sets forth the amortized cost and estimated fair value of fixed maturities, available for sale, at June 30, 2013, by contractual maturity.  Actual maturities will differ from contractual maturities because certain borrowers may have the right to call or prepay obligations with or without penalties.  In addition, structured securities (such as asset-backed securities, collateralized debt obligations, commercial mortgage-backed securities, mortgage pass-through securities and collateralized mortgage obligations, collectively referred to as "structured securities") frequently include provisions for periodic principal payments and permit periodic unscheduled payments.

Net Realized Investment Gains (Losses)

During the first six months of 2013, we recognized net realized investment gains of $18.5 million, which were comprised of $29.6 million of net gains from the sales of investments (primarily fixed maturities) with proceeds of $.9 billion and the decrease in fair value of certain fixed maturity investments with embedded derivatives of $10.5 million and $.6 million of writedowns of investments for other than temporary declines in fair value recognized through net income.

During the first six months of 2012, we recognized net realized investment gains of $54.8 million, which were comprised of $61.2 million of net gains from the sales of investments (primarily fixed maturities) with proceeds of $1.3 billion, the increase in fair value of certain fixed maturity investments with embedded derivatives of $5.0 million, and $11.4 million of writedowns of investments for other than temporary declines in fair value recognized through net income.

At June 30, 2013, fixed maturity securities in default or considered nonperforming had an aggregate amortized cost of $.4 million and a carrying value of $.5 million.

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

During the six months ended June 30, 2013, we sold $181.3 million of fixed maturity investments which resulted in gross investment losses (before income taxes) of $3.4 million.  We sell securities at a loss for a number of reasons including, but not limited to:  (i) changes in the investment environment; (ii) expectation that the market value could deteriorate further; (iii) 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 cash flows.

We regularly evaluate all of our investments with unrealized losses for possible impairment.  Our assessment of whether unrealized losses are "other than temporary" requires significant judgment.  Factors considered include:  (i) the extent to which fair value is less than the cost basis; (ii) the length of time that the fair value has been less than cost; (iii) whether the unrealized loss is 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 is investment-grade and/or has been downgraded since its purchase; (vi) whether the issuer is current on all payments in accordance with the contractual terms of the investment and is expected to meet all of its obligations under the terms of the investment; (vii) whether we intend to sell the investment or it is more likely than not that circumstances will 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 may 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.

Impairment losses on equity securities are recognized in net income.  The manner in which impairment losses on fixed maturity securities, available for sale, are recognized in the financial statements is dependent on the facts and circumstances related to the specific security.  If we intend to sell a security or it is more likely than not that we would be required to sell a security before the recovery of its amortized cost, the security is other-than-temporarily impaired and the full amount of the impairment is recognized as a loss through earnings.  If we do not expect to recover the amortized cost basis, we do not plan to sell the security, and if it is not more likely than not that we would be required to sell a security before the recovery of its amortized cost, less any current period credit loss, the recognition of the other-than-temporary impairment is bifurcated.  We recognize the credit loss portion in net income and the noncredit loss portion in accumulated other comprehensive income.

We estimate the amount of the credit loss component of a fixed maturity security impairment as the difference between amortized cost and the present value of the expected cash flows of the security.  The present value is determined using the best estimate of future cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security.  The methodology and assumptions for establishing the best estimate of future cash flows vary depending on the type of security.

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 excess spread, subordination and guarantees.  For corporate bonds, cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using bond specific facts and circumstances. The previous amortized cost basis less the impairment recognized in net income becomes the security's new cost basis.  We accrete the new cost basis to the estimated future cash flows over the expected remaining life of the security, except when the security is in default or considered nonperforming.

The remaining noncredit impairment, which is recorded in accumulated other comprehensive income, is the difference between the security's estimated fair value and our best estimate of future cash flows discounted at the effective interest rate prior to impairment.  The remaining noncredit impairment typically represents changes in the market interest rates, current market liquidity and risk premiums.  As of June 30, 2013, other-than-temporary impairments included in accumulated other comprehensive income of $4.8 million (before taxes and related amortization) related to structured securities.

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 six months ended June 30, 2013 and 2012 (dollars in millions):

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 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 that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that such securities have been in a continuous unrealized loss position, at June 30, 2013 (dollars in millions):

Based on management's current assessment of investments with unrealized losses at June 30, 2013, the Company believes the issuers of the securities will continue to meet their obligations (or with respect to equity-type securities, the investment value will recover to its cost basis).  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.

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 and warrants were exercised and restricted stock was vested.  The dilution from options, warrants and restricted shares is calculated using the treasury stock method.  Under this method, we assume the proceeds from the exercise of the options and warrants (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 and warrants (or the vesting of the restricted stock and performance units). Initially, the 7.0% Debentures were convertible into 182.1494 shares of our common stock for each $1,000 principal amount of 7.0% Debentures, which is equivalent to an initial conversion price of approximately $5.49 per share. The conversion rate is subject to adjustment following the occurrence of certain events (including the payment of dividends on our common stock) in accordance with the terms of an indenture dated as of October 16, 2009 (the "7.0% Indenture"). At June 30, 2013, the conversion rate was 184.3127 shares of our common stock for each $1,000 principal amount of 7.0% Debentures outstanding. On July 1, 2013, the Company issued a conversion right termination notice to holders of the 7.0% Debentures as further discussed in the note to the consolidated financial statements entitled "Notes Payable - Direct Corporate Obligations".

BUSINESS SEGMENTS
BUSINESS SEGMENTS
BUSINESS SEGMENTS

The Company manages its business through the following operating segments: Bankers Life, Washington National and Colonial Penn, which are defined on the basis of product distribution; Other CNO Business, comprised primarily of products we no longer sell actively; and corporate operations, comprised of holding company activities and certain noninsurance company businesses.  

We measure segment performance by excluding net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), equity in earnings of certain non-strategic investments and earnings attributable to non-controlling interests and loss on extinguishment of debt 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 realized investment gains (losses), and a long-term focus is necessary to maintain profitability over the life of the business.

Net realized investment gains (losses), fair value changes in embedded derivative liabilities (net of related amortization), equity in earnings of certain non-strategic investments and earnings attributable to non-controlling interests and loss on extinguishment of debt depend on market conditions and 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.

ACCOUNTING FOR DERIVATIVES
ACCOUNTING FOR DERIVATIVES
ACCOUNTING FOR DERIVATIVES

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.  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.  We reflect changes in the estimated fair value of these options in net investment income (classified as investment income from policyholder and reinsurer accounts and other special-purpose portfolios).  Net investment gains (losses) related to fixed index products were $75.9 million and $18.0 million in the six months ended June 30, 2013 and 2012, respectively. These amounts were substantially offset by a corresponding change to insurance policy benefits.  The estimated fair value of these options was $114.1 million and $54.4 million at June 30, 2013 and December 31, 2012, respectively.  We classify these instruments as other invested assets.

The Company accounts for the options attributed to the policyholder for the estimated life of the annuity contract as embedded derivatives.  The Company purchases options to hedge liabilities for the next policy period approximately on each policy anniversary date and must estimate the fair value of the forward embedded options related to the policies.  These accounting requirements often create volatility in the earnings from these products.  We record the changes in the fair values of the embedded derivatives in earnings as a component of insurance policy benefits.  The fair value of these derivatives, which are classified as "liabilities for interest-sensitive products", was $796.3 million at June 30, 2013 and $734.0 million at December 31, 2012. We recognized an increase (reduction) to earnings of $18.5 million and $(10.6) million in the second quarters of 2013 and 2012, respectively, and $20.6 million and $(3.7) million in the first six months of 2013 and 2012, respectively, from the volatility caused by the accounting requirements to record embedded options at fair value.

If the counterparties for the call options we hold fail to meet their obligations, we may have to recognize a loss.  We limit our exposure to such a loss by diversifying among several counterparties believed to be strong and creditworthy.  At June 30, 2013, substantially all of our counterparties were rated "BBB+" or higher by Standard & Poor's Corporation ("S&P").

Certain of our reinsurance payable balances contain embedded derivatives.  Such derivatives had an estimated fair value of $2.6 million and $5.5 million at June 30, 2013 and December 31, 2012, respectively.  We record the change in the fair value of these derivatives as a component of investment income (classified as investment income from policyholder and reinsurer accounts and other special-purpose portfolios).  We maintain the investments related to these agreements in our trading securities account, which we carry at estimated fair value with changes in such value recognized as investment income (also classified as investment income from policyholder and reinsurer accounts and other special-purpose portfolios).  The change in value of these trading securities offsets the change in value of the embedded derivatives.

We purchase certain fixed maturity securities that contain embedded derivatives that are required to be bifurcated from the instrument and held at fair value on the consolidated balance sheet. For certain of these securities, we have elected the fair value option to carry the entire security at fair value with changes in fair value reported in net income for operational ease. Such securities totaled $176.6 million and $196.6 million at June 30, 2013 and December 31, 2012, respectively.

The cost of reinsurance ceded totaled $55.1 million and $59.3 million in the second quarters of 2013 and 2012, respectively, and $107.1 million and $116.5 million in the first six months of 2013 and 2012, respectively. We deduct this cost from insurance policy income.  Reinsurance recoveries netted against insurance policy benefits totaled $39.1 million and $54.2 million in the second quarters of 2013 and 2012, respectively, and $92.7 million and $115.8 million in the first six months of 2013 and 2012, respectively.

From time-to-time, we assume insurance from other companies.  Any costs associated with the assumption of insurance are amortized consistent with the method used to amortize deferred acquisition costs.  Reinsurance premiums assumed totaled $15.4 million and $22.9 million in the second quarters of 2013 and 2012, respectively, and $29.1 million and $38.8 million in the first six months of 2013 and 2012, respectively.  Reinsurance premiums included amounts assumed pursuant to marketing and quota-share agreements with Coventry Health Care ("Coventry") of $10.8 million and $17.7 million in the second quarters of 2013 and 2012, respectively, and $19.7 million and $28.5 million in the first six months of 2013 and 2012, respectively.

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 loss on extinguishment of debt of $7.7 million and $65.4 million in the three and six months ended June 30, 2013, respectively, was treated as a discrete item.

Our income tax expense includes deferred income taxes arising from temporary differences between the financial reporting and tax bases of assets and liabilities, capital loss carryforwards and net operating loss carryforwards ("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, including our indepth review in the third quarter of each year in conjunction with our annual financial planning process. The realization of our deferred tax assets depends upon generating sufficient future taxable income during the periods in which our temporary differences become deductible and before our capital loss carryforwards and NOLs expire.

In the first six months of 2013, we reduced our deferred tax valuation allowance by $15.5 million (of which, $5.0 million was recognized in the second quarter of 2013) resulting from the utilization of capital loss carryforwards during the period. We will continue to assess the need for a valuation allowance in the future. If future results are less than projected, a valuation allowance may be required to reduce the deferred tax assets, which could have a material impact on our results of operations in the period in which it is recorded.

Recovery of our deferred tax assets is dependent on achieving the future taxable income used in our deferred tax valuation model and failure to do so would 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.  In addition, the use of the Company's NOLs is dependent, in part, on whether the Internal Revenue Service (the "IRS") ultimately agrees with the tax position we have taken in our tax returns with respect to the classification of the loss we recognized as a result of the transfer of the stock of Senior Health Insurance Company of Pennsylvania ("Senior Health") to Senior Health Care Oversight Trust, an independent trust (the "Independent Trust").

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 an ownership change.  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 (including upon conversion of our outstanding 7.0% Debentures), 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 (2.70 percent at June 30, 2013), and the annual restriction could effectively eliminate 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 June 30, 2013, we were below the 50 percent ownership change level that would trigger further impairment of our ability to utilize our NOLs.

As of June 30, 2013, we had $3.6 billion of federal NOLs and $.8 billion of capital loss carryforwards. The following table summarizes the expiration dates of our loss carryforwards assuming: the IRS does not ultimately agree with the position we have taken with respect to the loss on our investment in Senior Health; and does not reflect the impact of the agreement on the terms of a settlement we reached with the IRS in July 2013 related to the classification of cancellation of indebtedness income ("CODI") resulting from the bankruptcy of our Predecessor both as further described below (dollars in millions):

 _________________________
(a)
The life/non-life allocation summarized above does not reflect the agreement on the terms of a settlement we reached with the IRS in July 2013 with respect to the allocation of CODI.  Approximately $315 million of the non-life NOLs expiring in 2023 will be characterized as life NOLs expiring in 2018. The impact of the agreement is expected to be reflected in our financial statements for the three month period ended September 30, 2013, pending receipt of the final settlement agreement.
(b)
The allocation of the capital loss carryforwards summarized above assumes the IRS does not ultimately agree with the tax position we have taken with respect to our investment in Senior Health, which was worthless when it was transferred to the Independent Trust in 2008. If the IRS ultimately agrees with our tax position of classifying this loss as ordinary, capital loss carryforwards expiring in 2013 would decrease and life NOLs expiring in 2023 would increase by $742 million.

We had deferred tax assets related to NOLs for state income taxes of $16.1 million and $16.2 million at June 30, 2013 and December 31, 2012, respectively.  The related state NOLs are available to offset future state taxable income in certain states through 2019.

In July 2006, the Joint Committee of Taxation accepted the audit and the settlement which characterized $2.1 billion of the tax losses on our Predecessor's investment in Conseco Finance Corp. as life company losses and the remaining $3.8 billion as non-life losses prior to the application of the CODI attribute reductions described below.

The Code provides that any income realized as a result of the CODI in bankruptcy must reduce NOLs. We realized $2.5 billion of CODI when we emerged from bankruptcy. Pursuant to the Company's interpretation of the tax law, the CODI reductions were all used to reduce non-life NOLs and this position has been taken in our tax returns. However, the IRS was not in agreement with our position. An agreement on the terms of a settlement was reached in July 2013. Due to uncertainties with respect to the position the IRS could take and limitations on our ability to utilize NOLs based on projected life and non-life income, we had consistently considered the $631 million of CODI to be a reduction to life NOLs when determining our valuation allowance. Under the terms of the agreement, approximately $315 million of the $631 million of CODI will be treated as a reduction to the non-life NOLs. We expect the final closing agreement to result in a reduction to our valuation allowance of approximately $70.0 million which will be recognized in the three month period ended September 30, 2013, excluding the impacts of any other tax developments.

We recognized a $742 million loss on our investment in Senior Health which was worthless when it was transferred to the Independent Trust in 2008. We have treated the loss as a capital loss when determining the deferred tax benefit we may receive. We also established a full valuation allowance as we believe we will not generate capital gains to utilize the benefit. However, due to uncertainties in the Code, we have reflected this loss as an ordinary loss in our tax return, contrary to certain IRS rulings. We are exploring the use of tax planning strategies to utilize this loss, assuming it is ultimately determined to be a capital loss. We have not been able to conclude that the potential strategies we have identified are feasible and/or prudent as of June 30, 2013. If classifying this loss as ordinary is ultimately determined to be correct, our valuation allowance would be reduced by approximately $130 million based on the income projections used in determining our valuation allowance.

Due to the uncertainty in tax law, we were not able to conclude that a tax position for the repurchase premium related to the repurchase of our 7% Debentures on September 28, 2012 and March 27, 2013, was more likely than not to be sustained. We recently engaged outside counsel and received external evidence after June 30, 2013 which supports our position that deductions with respect to a portion of the repurchase premium paid in 2012 and 2013 should be allowed under Section 249 of the Code. We expect to record a tax benefit of approximately $14.0 million in the three months ended September 30, 2013, related to the change in facts regarding the deductibility of a portion of the repurchase premium, excluding the impacts of any other tax developments.

Tax years 2004 and 2008 through 2010 are open to examination by the IRS through September 2014, while tax year 2011 is open through September 2015.  The Company's various state income tax returns are generally open for tax years 2009 through 2011 based on the individual state statutes of limitation. Generally, for tax years which generate NOLs, capital losses or tax credit carryforwards, the statute of limitations does not close until the expiration of the statute of limitations for the tax year in which such carryforwards are utilized.

Senior Secured Credit Agreement

On September 28, 2012, the Company entered into a senior secured credit agreement, providing for: (i) a $425.0 million six-year term loan facility ($394.0 million remains outstanding at June 30, 2013); (ii) a $250.0 million four-year term loan facility ($212.5 million remains outstanding at June 30, 2013); and (iii) a $50.0 million three-year revolving credit facility, with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders from time to time party thereto (the "Senior Secured Credit Agreement"). The Senior Secured Credit Agreement is guaranteed by the Subsidiary Guarantors (as defined below) and secured by a first-priority lien (which ranks pari passu with the liens securing the 6.375% Notes) on substantially all of the Company's and the Subsidiary Guarantors' assets. As of June 30, 2013, no amounts have been borrowed under the revolving credit facility.

The revolving credit facility includes an uncommitted subfacility for swingline loans of up to $5.0 million, and up to $5.0 million of the revolving credit facility is available for the issuance of letters of credit. The six-year term loan facility amortizes in quarterly installments in amounts resulting in an annual amortization of 1% and the four-year term loan facility amortizes in quarterly installments resulting in an annual amortization of 20% during the first and second years and 30% during the third and fourth years. Subject to certain conditions, the Company may incur additional incremental loans under the Senior Secured Credit Agreement in an amount of up to $250.0 million.

In May 2013, we amended our Senior Secured Credit Agreement. Pursuant to the amended terms, the applicable interest rates were decreased. The new interest rates with respect to loans under: (i) the six-year term loan facility are, at the Company's option, equal to a eurodollar rate, plus 2.75% per annum, or a base rate, plus 1.75% per annum, subject to a eurodollar rate "floor" of 1.00% and a base rate "floor" of 2.25% (previously a eurodollar rate, plus 3.75% per annum, or a base rate, plus 2.75% per annum, subject to a eurodollar rate "floor" of 1.25% and a base rate "floor" of 2.25%); (ii) the four-year term loan facility are, at the Company's option, equal to a eurodollar rate, plus 2.25% per annum, or a base rate, plus 1.25% per annum, subject to a eurodollar rate "floor" of .75% and a base rate "floor" of 2.00% (previously a eurodollar rate, plus 3.25% per annum, or a base rate, plus 2.25% per annum, subject to a eurodollar rate "floor" of 1.00% and a base rate "floor" of 2.00%); and (iii) the revolving credit facility will be, at the Company's option, equal to a eurodollar rate, plus 3.00% per annum, or a base rate, plus 2.00% per annum, in each case, with respect to revolving credit facility borrowings only, subject to certain step-downs based on the debt to total capitalization ratio of the Company (previously a eurodollar rate, plus 3.50% per annum, or a base rate, plus 2.50% per annum, subject to certain step-downs based on the debt to total capitalization ratio of the Company). At June 30, 2013, the interest rates on the six-year term loan facility and the four-year term loan facility were 3.75% and 3.00%, respectively.

Other changes to the Senior Secured Credit Agreement included:

(i)
modifications of mandatory prepayments resulting from certain restricted payments made (including any common stock dividends and share repurchases) as defined in the Senior Secured Credit Agreement. Pursuant to the amended terms, the amount of the mandatory prepayment is: (a) 100% of the amount of certain restricted payments provided that if, as of the end of the fiscal quarter immediately preceding such restricted payment, the debt to total capitalization ratio is: (x) equal to or less than 25.0% but greater than 20.0%, the prepayment requirement shall be reduced to 33.33% (previously less than or equal to 22.5% but greater than 17.5%); or (y) equal to or less than 20.0%, the prepayment requirement shall not apply (previously equal to or less than 17.5%); and

(ii)
that there will be a 1.00% fee in connection with any repricing of the six-year term loan facility that reduces the interest rate prior to the date that is six months after the closing of the amendment of the Senior Secured Credit Agreement.

In the first six months of 2013, we made mandatory prepayments of $20.4 million in an amount equal to 33.33% of our share repurchases and common stock dividend payments, as required under the terms of our Senior Secured Credit Agreement. We also made additional payments of $17.7 million to cover the remaining portion of the scheduled quarterly principal payments due under the Senior Secured Credit Agreement.

In the second quarter of 2013, we recognized a loss on extinguishment of debt totaling $2.9 million reflecting expenses related to the amendment of the Senior Secured Credit Agreement and the write-off of unamortized discount and issuance costs associated with prepayments on the Senior Secured Credit Agreement.

Mandatory prepayments of the Senior Secured Credit Agreement will be required, subject to certain exceptions, in an amount equal to: (i) 100% of the net cash proceeds from certain asset sales or casualty events; (ii) 100% of the net cash proceeds received by the Company or any of its restricted subsidiaries from certain debt issuances; and (iii) 100% of the amount of certain restricted payments made (including any common stock dividends and share repurchases) as defined in the Senior Secured Credit Agreement provided that if, as of the end of the fiscal quarter immediately preceding such restricted payment, the debt to total capitalization ratio is: (x) equal to or less than 25.0%, but greater than 20.0%, the prepayment requirement shall be reduced to 33.33%; or (y) equal to or less than 20.0%, the prepayment requirement shall not apply.

Notwithstanding the foregoing, no mandatory prepayments pursuant to item (i) in the preceding paragraph shall be required if: (x) the debt to total capitalization ratio is equal or less than 20% and (y) either (A) the financial strength rating of certain of the Company's insurance subsidiaries is equal or better than A- (stable) from A.M. Best Company ("A.M. Best") or (B) the Senior Secured Credit Agreement is rated equal or better than BBB- (stable) from S&P and Baa3 (stable) by Moody's Investor Services, Inc. ("Moody's").

The Senior Secured Credit Agreement requires the Company to maintain (each as calculated in accordance with the Senior Secured Credit Agreement): (i) a debt to total capitalization ratio of not more than 27.5 percent (such ratio was 19.1 percent at June 30, 2013); (ii) an interest coverage ratio of not less than 2.50 to 1.00 for each rolling four quarters (or, if less, the number of full fiscal quarters commencing after the effective date of the Senior Secured Credit Agreement) (such ratio was 7.84 to 1.00 for the period ended June 30, 2013); (iii) 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 376 percent at June 30, 2013); and (iv) a combined statutory capital and surplus for the Company's insurance subsidiaries of at least $1,300.0 million (combined statutory capital and surplus at June 30, 2013, was $1,864.9 million).

6.375% Notes

On September 28, 2012, we issued $275.0 million in aggregate principal amount of 6.375% Notes pursuant to an Indenture, dated as of September 28, 2012 (the "6.375% Indenture"), among the Company, the subsidiary guarantors party thereto (the "Subsidiary Guarantors") and Wilmington Trust, National Association, as trustee and as collateral agent. The 6.375% Notes mature on October 1, 2020. Interest on the 6.375% Notes accrues at a rate of 6.375% per annum and is payable semiannually in arrears on April 1 and October 1 of each year, commencing on April 1, 2013. The 6.375% Notes and the guarantees thereof (the "Guarantees") are senior secured obligations of the Company and the Subsidiary Guarantors and rank equally in right of payment with all of the Company's and the Subsidiary Guarantors' existing and future senior obligations, and senior to all of the Company's and the Subsidiary Guarantors' future subordinated indebtedness. The 6.375% Notes are secured by a first-priority lien on substantially all of the assets of the Company and the Subsidiary Guarantors, subject to certain exceptions. The 6.375% Notes and the Guarantees are pari passu with respect to security and in right of payment with all of the Company's and the Subsidiary Guarantors' existing and future secured indebtedness under the Senior Secured Credit Agreement. The 6.375% Notes are structurally subordinated to all of the liabilities and preferred stock of each of the Company's insurance subsidiaries, which are not guarantors of the 6.375% Notes.

Under the 6.375% Indenture, the Company can make Restricted Payments (as such term is defined in the 6.375% Indenture) up to a calculated limit, provided that the Company's pro forma risk-based capital ratio exceeds 225% after giving effect to the Restricted Payment and certain other conditions are met. Restricted Payments include, among other items, repurchases of common stock and cash dividends on common stock (to the extent such dividends exceed $30 million in the aggregate in any calendar year). Restricted payments do not include cash paid to purchase our outstanding 7.0% Debentures pursuant to the previously announced tender offer discussed below.

The limit of Restricted Payments permitted under the 6.375% Indenture is the sum of (x) 50% of the Company's "Net Excess Cash Flow" (as defined in the 6.375% Indenture) for the period (taken as one accounting period) from July 1, 2012 to the end of the Company's most recently ended fiscal quarter for which financial statements are available at the time of such Restricted Payment, (y) $175.0 million and (z) certain other amounts specified in the 6.375% Indenture. Based on the provisions set forth in the 6.375% Indenture and the Company's Net Excess Cash Flow for the period from July 1, 2012 through June 30, 2013, the Company could have made additional Restricted Payments under this 6.375% Indenture covenant of approximately $238 million as of June 30, 2013. This limitation on Restricted Payments does not apply if the Debt to Total Capitalization Ratio (as defined in the 6.375% Indenture) as of the last day of the Company's most recently ended fiscal quarter for which financial statements are available that immediately precedes the date of any Restricted Payment, calculated immediately after giving effect to such Restricted Payment and any related transactions on a pro forma basis, is equal to or less than 17.5%.

7.0% Debentures

On March 28, 2013, the Company completed the cash tender offer (the "Offer") for $59.3 million aggregate principal amount of its 7.0% Debentures for an aggregate purchase price of $124.8 million. The Offer was conducted as part of our previously announced securities repurchase program.

Pursuant to the terms of the Offer, holders of the 7.0% Debentures who tendered their 7.0% Debentures prior to the expiration date, received, for each $1,000 principal amount of such 7.0% Debentures, a cash purchase price (the "Purchase Price") equal to the sum of: (i) the average volume weighted average price of our common stock (as defined in the Offer) ($11.2393 at the close of trading on March 27, 2013) multiplied by 183.5145; plus (ii) a fixed cash amount of $61.25. The final Purchase Price per $1,000 principal amount of 7.0% Debentures was $2,123.82. In addition to the Purchase Price, holders received accrued and unpaid interest on any 7.0% Debentures that were tendered to, but excluding, the settlement date of the Offer.

In May 2013, we repurchased $4.5 million principal amount of the 7.0% Debentures for an aggregate purchase price of $9.4 million.

In the first six months of 2013, we recognized a loss on extinguishment of debt totaling $62.5 million as a result of the Offer and repurchase of 7.0% Debentures described above, the write-off of unamortized discount and issuance costs associated with the 7.0% Debentures that were repurchased and other transaction costs. Additional paid-in capital was also reduced by $12.6 million to extinguish the beneficial conversion feature associated with a portion of the 7.0% Debentures that were repurchased.

On July 1, 2013, the Company issued a conversion right termination notice (the “Conversion Termination Notice”) to holders of the 7.0% Debentures. The Company elected to terminate the right to convert the 7.0% Debentures into shares of its common stock, par value $0.01 per share, effective as of July 30, 2013 (the “Conversion Termination Date”). Holders of the 7.0% Debentures were able to exercise their conversion right at any time on or prior to the close of business on July 30, 2013. Holders exercising their conversion right received 184.3127 shares of common stock per $1,000 principal amount of 7.0% Debentures converted.

7.0% Debentures submitted for conversion were deemed paid in full and the Company has no further obligation with respect to such 7.0% Debentures. Holders of $25.7 million in aggregate principal amount of the 7.0% Debentures exercised their conversion right and received 4.7 million shares of our common stock.

As of July 31, 2013, $3.5 million in aggregate principal amount of the 7.0% Debentures remained outstanding.

INVESTMENT BORROWINGS
INVESTMENT BORROWINGS
INVESTMENT BORROWINGS

Three of the Company's insurance subsidiaries (Conseco Life Insurance Company ("Conseco Life"), Washington National Insurance Company and Bankers Life and Casualty Company ("Bankers Life")) are members of the Federal Home Loan Bank ("FHLB").  As members of the FHLB, Conseco Life, Washington National Insurance Company and Bankers Life have the ability to borrow on a collateralized basis from the FHLB.  Conseco Life, Washington National Insurance Company and Bankers Life are required to hold certain minimum amounts of FHLB common stock as a condition of membership in the FHLB, and additional amounts based on the amount of the borrowings.  At June 30, 2013, the carrying value of the FHLB common stock was $92.5 million.  As of June 30, 2013, collateralized borrowings from the FHLB totaled $1.8 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 $2.3 billion at June 30, 2013, 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.  Interest expense of $13.6 million and $14.4 million in the first six months of 2013 and 2012, respectively, was recognized related to the borrowings.

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 current market interest rates.  At June 30, 2013, the aggregate yield maintenance fee to prepay all fixed rate borrowings was $48.0 million.

As part of our investment strategy, we may enter into repurchase agreements to increase our investment return. Pursuant to such agreements, the Company sells securities subject to an obligation to repurchase the same securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, these repurchase agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities. Such borrowings totaled $27.6 million at June 30, 2013. The borrowings mature as follows: $20.9 million - within 30 days; and $6.7 million - between 30 and 90 days.

The primary risks associated with short-term collateralized borrowings are: (i) a substantial decline in the market value of the margined security; and (ii) that a counterparty may be unable to perform under the terms of the contract or be unwilling to extend such financing in future periods especially if the liquidity or value of the margined security has declined. Exposure is limited to any depreciation in value of the related securities.

At June 30, 2013, investment borrowings consisted of:  (i) collateralized borrowings from the FHLB of $1.8 billion; (ii) repurchase agreements of $27.6 million; and (iii) other borrowings of $.6 million.

At December 31, 2012, investment borrowings consisted of:  (i) collateralized borrowings from the FHLB of $1.7 billion; and (ii) other borrowings of $.8 million.

In May 2011, the Company announced a common share repurchase program of up to $100.0 million. In February 2012, June 2012 and December 2012, the Company's Board of Directors approved, in aggregate, an additional $500.0 million to repurchase the Company's outstanding securities. In the first six months of 2013, we repurchased 4.4 million shares of common stock for $50.0 million, under the securities repurchase program. The Company purchased $63.8 million aggregate principal amount of our 7.0% Debentures in the first six months of 2013 as further discussed in the note to the consolidated financial statements entitled "Notes Payable - Direct Corporate Obligations". Such repayments were made pursuant to our securities repurchase program. The Company had remaining repurchase authority of $165.7 million as of June 30, 2013.

In May 2012, we initiated a common stock dividend program. In the first six months of 2013, dividends declared and paid on common stock were $0.05 per share totaling $11.1 million.
SALES INDUCEMENTS
SALES INDUCEMENTS
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 holders 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 $2.5 million and $2.3 million during the six months ended June 30, 2013 and 2012, respectively.  Amounts amortized totaled $13.3 million and $14.3 million during the six months ended June 30, 2013 and 2012, respectively.  The unamortized balance of deferred sales inducements at June 30, 2013 and December 31, 2012 was $115.7 million and $126.5 million, respectively.  The balance of insurance liabilities for persistency bonus benefits was $31.3 million and $34.6 million at June 30, 2013 and December 31, 2012, respectively.
ASSETS AND LIABILITIES SUBJECT TO OFFSETTING DISCLOSURE REQUIREMENTS
ASSETS AND LIABILITIES SUBJECT TO OFFSETTING DISCLOSURE REQUIREMENTS
ASSETS AND LIABILITIES SUBJECT TO OFFSETTING DISCLOSURE REQUIREMENTS

Call options

As described in the note to the consolidated financial statements entitled "Accounting for Derivatives", we buy call options (including call spreads) referenced to 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. We limit our exposure to the counterparties failing to meet their obligation with respect to the call options by diversifying among several counterparties believed to be strong and credit worthy. The call options are free-standing derivatives and are recorded at fair value in the Company's consolidated balance sheet. The Company and its subsidiaries are parties to master netting arrangements with its counterparties related to entering into various derivative contracts. However, the offsetting of assets and liabilities is not applicable to the derivative contracts that were in place at June 30, 2013 or December 31, 2012. The counterparties do not provide collateral to the Company related to their obligations under the call options.

Repurchase agreements

As described in the note to the consolidated financial statements entitled "Investment Borrowings", we may enter into agreements under which we sell securities subject to an obligation to repurchase the same securities. These repurchase agreements are accounted for as collateralized financing arrangements and not as a sale and subsequent repurchase of securities. The obligation to repurchase the securities is reflected as investment borrowings in the Company's consolidated balance sheet, while the securities underlying the repurchase agreements remain in the respective investment asset accounts. There is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities. In addition, as the Company does not currently have any outstanding reverse repurchase agreements, there is no such offsetting to be done with the repurchase agreements.

The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral would be used to settle the fair value of the repurchase agreement should the Company be in default (e.g., fails to make an interest payment to the counterparty). If the counterparty were to default (e.g., declare bankruptcy), the Company could cancel the repurchase agreement (i.e., cease payment of principal and interest), and attempt collection on the amount of collateral value in excess of the repurchase agreement fair value. The collateral is held by a third party financial institution in the counterparty's custodial account. The counterparty has the right to sell or repledge the investment securities.

RECENTLY ISSUED ACCOUNTING STANDARDS
RECENTLY ISSUED ACCOUNTING STANDARDS
ECENTLY ISSUED ACCOUNTING STANDARDS

Pending Accounting Standards

In July 2013, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance regarding the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. Such guidance will require an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except under certain circumstances as further described in the guidance.

Such guidance does not require new recurring disclosures. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The guidance should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
    
Adopted Accounting Standards

In December 2011, the FASB issued authoritative guidance regarding disclosures about offsetting assets and liabilities. The guidance requires an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The guidance is effective for annual and interim reporting periods beginning on or after January 1, 2013, with retrospective disclosures required for all comparative periods presented. In January 2013, the FASB issued authoritative guidance that limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements and securities lending transactions to the extent that they are: (i) offset in the financial statements; or (ii) subject to an enforceable master netting arrangement or similar agreement. Such disclosures are included in the note to the consolidated financial statements entitled "Assets and Liabilities Subject to Offsetting Disclosure Requirements".

INVESTMENTS IN VARIABLE INTEREST ENTITIES
INVESTMENTS IN VARIABLE INTEREST ENTITIES
INVESTMENTS IN VARIABLE INTEREST ENTITIES

We have concluded that we are the primary beneficiary with respect to certain variable interest entities ("VIEs"), which are consolidated in our financial statements.  The following is a description of our significant investments in VIEs:

All of the VIEs are collateralized loan trusts that were established to issue securities and use the proceeds to principally invest in corporate loans and other permitted investments (including a new VIE which was consolidated in the first quarter of 2013).  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 further commitments to the VIEs.

Certain of our insurance 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 table provides supplemental information about the assets and liabilities of the VIEs which have been consolidated in accordance with authoritative guidance (dollars in millions):

The investment portfolios held by the VIEs are primarily comprised of corporate bank loans which are almost entirely rated below-investment grade.  At June 30, 2013, such loans had an amortized cost of $1,087.9 million; gross unrealized gains of $4.2 million; gross unrealized losses of $4.2 million; and an estimated fair value of $1,087.9 million.

The following table sets forth the amortized cost and estimated fair value of the investments held by the VIEs at June 30, 2013, by contractual maturity.  Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without penalties.

During the first six months of 2013, we recognized net realized investment losses on the VIE investments of $.3 million, which were comprised of $.3 million of net gains from the sales of fixed maturities, and $.6 million of writedowns of investments for other than temporary declines in fair value recognized through net income.  During the first six months of 2012, we recognized net realized investment losses on the VIE investments of $.2 million, which were comprised of $.2 million of net gains from the sales of fixed maturities, and $.4 million of writedowns of investments for other than temporary declines in fair value recognized through net income.

At June 30, 2013, there were no investments held by the VIEs that were in default.

During the first six months of 2013, no investments held by the VIEs were sold which resulted in gross investment losses.

At June 30, 2013, the VIEs held:  (i) investments with a fair value of $541.5 million and gross unrealized losses of $4.2 million that had been in an unrealized loss position for less than twelve months; and (ii) investments with a fair value of $11.3 million and gross unrealized losses of nil that had been in an unrealized loss position for greater than twelve months.

The investments held by the VIEs are evaluated for other-than-temporary declines in fair value in a manner that is consistent with the Company's fixed maturities, available for sale.

In addition, the Company, in the normal course of business, makes passive investments in structured securities issued by VIEs for which the Company is not the investment manager.  These structured securities include asset-backed securities, collateralized debt obligations, commercial mortgage-backed securities, residential mortgage-backed securities and collateralized mortgage obligations.  Our maximum exposure to loss on these securities is limited to our cost basis in the investment.  We have determined that we are not the primary beneficiary of these structured securities due to the relative size of our investment in comparison to the total principal amount of the individual structured securities and the level of credit subordination which reduces our obligation to absorb gains or losses.

At June 30, 2013, we hold investments in various limited partnerships, in which we are not the primary beneficiary, totaling $29.6 million (classified as other invested assets).  At June 30, 2013, we had unfunded commitments to these partnerships of $39.5 million.  Our maximum exposure to loss on these investments is limited to the amount of our investment.
FAIR VALUE MEASUREMENTS
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, cash and cash equivalents, separate account assets and embedded derivatives.  We carry our company-owned life insurance policy, which is backed by a series of mutual funds, at its cash surrender value and our hedge fund investments at their net asset values; in both cases, we believe these values approximate their fair values. In addition, we disclose fair value for certain financial instruments, including mortgage loans and policy loans, 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 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 are primarily industry-standard models that consider various inputs such as interest rate, credit or issuer spreads, reported trades and other inputs that are observable or derived from observable information in the marketplace or are supported by observable levels at which transactions are executed in the marketplace.  Financial assets in this category primarily include:  certain public 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; certain mutual fund and hedge fund investments; and most short-term investments; and non-exchange-traded derivatives such as call options to hedge liabilities related to our fixed index annuity products. 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 (primarily certain below-investment grade privately placed 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. Any transfers between levels are reported as having occurred at the beginning of the period. There were no transfers between Level 1 and Level 2 in both the first six months of 2013 and 2012.

The vast majority of our fixed maturity and equity securities, including those held in trading portfolios and those held by consolidated VIEs, short-term 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.  Substantially all of our Level 2 fixed maturity securities and separate account assets were valued from independent pricing services.  Third party pricing services normally derive the 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 developed and 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.

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 24 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-free rates, risk premiums, 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 developed and discounted at an estimated market rate.  The pricing matrix utilizes a spread level to determine the market price for a security.  The credit spread generally incorporates the issuer's credit rating and other factors relating to the issuer's industry 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.

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 stale; 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 the prices received from third parties are not reflective of current market conditions.  In those instances, we may request additional pricing quotes or apply internally developed valuations.  However, the number of 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 include:  benchmark yields, reported trades, broker dealer quotes, issuer spreads, benchmark securities, bids, offers and reference data.  The Company categorizes such fair value measurements based upon asset classes and the underlying observable or unobservable inputs used to value such investments.

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 quotations; time value and volatility factors underlying options; market interest rates; and non-performance risk.  For certain embedded derivatives, we use actuarial assumptions in the determination of fair value.

For those financial instruments disclosed at fair value, we use the following methods and assumptions to determine the estimated fair values:

Mortgage loans and policy loans.  We discount future expected cash flows for loans included in our investment portfolio based on interest rates currently being offered for similar loans to borrowers with similar credit ratings.  We aggregate loans with similar characteristics in our calculations.  The fair value of policy loans approximates their carrying value.

Company-owned life insurance is backed by a series of mutual funds and is carried at cash surrender value which approximates estimated fair value.

Hedge fund investments are carried at their net asset values which approximates estimated fair value.

Insurance liabilities for interest-sensitive products.  We discount future expected cash flows based on interest rates currently being offered for similar contracts with similar maturities.

Cash and cash equivalents include commercial paper, invested cash and other investments purchased with original maturities of less than three months. We carry them at amortized cost, which approximates estimated fair value.

Insurance liabilities for interest-sensitive products.  We discount future expected cash flows based on interest rates currently being offered for similar contracts with similar maturities.

Investment borrowings, notes payable and borrowings related to variable interest entities.  For publicly traded debt, we use current fair values.  For other notes, we use discounted cash flow analyses based on our current incremental borrowing rates for similar types of borrowing arrangements.

____________________
(a)
The estimated fair value of insurance liabilities for interest-sensitive products was approximately equal to its carrying value at June 30, 2013 and December 31, 2012.  This was because interest rates credited on the vast majority of account balances approximate current rates paid on similar products and because these rates are not generally guaranteed beyond one year.


The following table presents additional information about assets and liabilities measured at fair value on a recurring basis and for which we have utilized significant unobservable (Level 3) inputs to determine fair value for the three months ended June 30, 2013 (dollars in millions):

For our fixed maturity securities, the majority of our transfers out of Level 3 are the result of obtaining a valuation from an independent pricing service which utilized observable inputs at the end of the period, whereas a broker quote was used as of the beginning of the period.
(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 three months ended June 30, 2013 (dollars in millions):

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 six months ended June 30, 2012 (dollars in millions):

At June 30, 2013, 93 percent of our Level 3 fixed maturities, available for sale, were investment grade and 39 percent and 54 percent of our Level 3 fixed maturities, available for sale, consisted of collateralized debt obligations and corporate securities, respectively.

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 reinsurer accounts 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 loss 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 following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at June 30, 2013 (dollars in millions):

________________________________
(a)
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 result in a significantly lower (higher) fair value measurement.
(b)
Asset-backed securities - The significant unobservable input used in the fair value measurement of our asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would result in a significantly lower (higher) fair value measurement.
(c)
Collateralized debt obligations - The significant unobservable inputs used in the fair value measurement of our collateralized debt obligations relate to collateral performance, including default rate, recoveries and constant prepayment rate, as well as discount margins of the underlying collateral. Significant increases (decreases) in default rate in isolation would result in a significantly lower (higher) fair value measurement. Generally, a significant increase (decrease) in the constant prepayment rate and recoveries in isolation would result in a significantly higher (lower) fair value measurement. Generally a significant increase (decrease) in discount margin in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the annual default rate is accompanied by a directionally similar change in the assumption used for discount margins and portfolio CCC % and a directionally opposite change in the assumption used for constant prepayment rate and recoveries. A tranche's payment priority and investment cost basis could alter generalized fair value outcomes.
(d)
Preferred stock - The significant unobservable inputs used in the fair value measurement of this preferred stock investment are the EBITDA multiple and revenue multiple. Generally, a significant increase (decrease) in the EBITDA or revenue multiples in isolation would result 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)
Interest sensitive products - The significant unobservable inputs used in the fair value measurement of our interest sensitive products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would lead to a higher (lower) fair value measurement. The discount rate is based on the Treasury rate adjusted by a margin. Increases (decreases) in the discount rates would lead 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.

The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at December 31, 2012 (dollars in millions):

Investments Classified by Contractual Maturity Date [Table Text Block] 
The following table sets forth the amortized cost and estimated fair value of fixed maturities, available for sale, at June 30, 2013, by contractual maturity.  Actual maturities will differ from contractual maturities because certain borrowers may have the right to call or prepay obligations with or without penalties.  In addition, structured securities (such as asset-backed securities, collateralized debt obligations, commercial mortgage-backed securities, mortgage pass-through securities and collateralized mortgage obligations, collectively referred to as "structured securities") frequently include provisions for periodic principal payments and permit periodic unscheduled payments.

Summary of Operating Loss Carryforwards [Table Text Block] 
As of June 30, 2013, we had $3.6 billion of federal NOLs and $.8 billion of capital loss carryforwards. The following table summarizes the expiration dates of our loss carryforwards assuming: the IRS does not ultimately agree with the position we have taken with respect to the loss on our investment in Senior Health; and does not reflect the impact of the agreement on the terms of a settlement we reached with the IRS in July 2013 related to the classification of cancellation of indebtedness income ("CODI") resulting from the bankruptcy of our Predecessor both as further described below (dollars in millions):

 _________________________
(a)
The life/non-life allocation summarized above does not reflect the agreement on the terms of a settlement we reached with the IRS in July 2013 with respect to the allocation of CODI.  Approximately $315 million of the non-life NOLs expiring in 2023 will be characterized as life NOLs expiring in 2018. The impact of the agreement is expected to be reflected in our financial statements for the three month period ended September 30, 2013, pending receipt of the final settlement agreement.
(b)
The allocation of the capital loss carryforwards summarized above assumes the IRS does not ultimately agree with the tax position we have taken with respect to our investment in Senior Health, which was worthless when it was transferred to the Independent Trust in 2008. If the IRS ultimately agrees with our tax position of classifying this loss as ordinary, capital loss carryforwards expiring in 2013 would decrease and life NOLs expiring in 2023 would increase by $742 million.

____________________
(a)
The estimated fair value of insurance liabilities for interest-sensitive products was approximately equal to its carrying value at June 30, 2013 and December 31, 2012.  This was because interest rates credited on the vast majority of account balances approximate current rates paid on similar products and because these rates are not generally guaranteed beyond one year.

(a)
For our fixed maturity securities, the majority of our transfers out of Level 3 are the result of obtaining a valuation from an independent pricing service which utilized observable inputs at the end of the period, whereas a broker quote was used as of the beginning of the period.
(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 three months ended June 30, 2013 (dollars in millions):

For our fixed maturity securities, the majority of our transfers out of Level 3 are the result of obtaining a valuation from an independent pricing service which utilized observable inputs at the end of the period, whereas a broker quote was used as of the beginning of the period.

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 six months ended June 30, 2013 (dollars in millions):

________________________________
(a)
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 result in a significantly lower (higher) fair value measurement.
(b)
Asset-backed securities - The significant unobservable input used in the fair value measurement of our asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would result in a significantly lower (higher) fair value measurement.
(c)
Collateralized debt obligations - The significant unobservable inputs used in the fair value measurement of our collateralized debt obligations relate to collateral performance, including default rate, recoveries and constant prepayment rate, as well as discount margins of the underlying collateral. Significant increases (decreases) in default rate in isolation would result in a significantly lower (higher) fair value measurement. Generally, a significant increase (decrease) in the constant prepayment rate and recoveries in isolation would result in a significantly higher (lower) fair value measurement. Generally a significant increase (decrease) in discount margin in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the annual default rate is accompanied by a directionally similar change in the assumption used for discount margins and portfolio CCC % and a directionally opposite change in the assumption used for constant prepayment rate and recoveries. A tranche's payment priority and investment cost basis could alter generalized fair value outcomes.
(d)
Preferred stock - The significant unobservable inputs used in the fair value measurement of this preferred stock investment are the EBITDA multiple and revenue multiple. Generally, a significant increase (decrease) in the EBITDA or revenue multiples in isolation would result 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)
Interest sensitive products - The significant unobservable inputs used in the fair value measurement of our interest sensitive products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would lead to a higher (lower) fair value measurement. The discount rate is based on the Treasury rate adjusted by a margin. Increases (decreases) in the discount rates would lead 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.

The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at December 31, 2012 (dollars in millions):

(a)
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 result in a significantly lower (higher) fair value measurement.
(b)
Asset-backed securities - The significant unobservable input used in the fair value measurement of our asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would result in a significantly lower (higher) fair value measurement.
(c)
Collateralized debt obligations - The significant unobservable inputs used in the fair value measurement of our collateralized debt obligations relate to collateral performance, including default rate, recoveries and constant prepayment rate, as well as discount margins of the underlying collateral. Significant increases (decreases) in default rate in isolation would result in a significantly lower (higher) fair value measurement. Generally, a significant increase (decrease) in the constant prepayment rate and recoveries in isolation would result in a significantly higher (lower) fair value measurement. Generally a significant increase (decrease) in discount margin in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the annual default rate is accompanied by a directionally similar change in the assumption used for discount margins and portfolio CCC % and a directionally opposite change in the assumption used for constant prepayment rate and recoveries.

[3] Collateralized debt obligations - The significant unobservable inputs used in the fair value measurement of our collateralized debt obligations relate to collateral performance, including default rate, recoveries and constant prepayment rate, as well as discount margins of the underlying collateral. Significant increases (decreases) in default rate in isolation would result in a significantly lower (higher) fair value measurement. Generally, a significant increase (decrease) in the constant prepayment rate and recoveries in isolation would result in a significantly higher (lower) fair value measurement. Generally a significant increase (decrease) in discount margin in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the annual default rate is accompanied by a directionally similar change in the assumption used for discount margins and portfolio CCC % and a directionally opposite change in the assumption used for constant prepayment rate and recoveries. A tranche's payment priority and investment cost basis could alter generalized fair value outcomes.
[6] rest sensitive products - The significant unobservable inputs used in the fair value measurement of our interest sensitive products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would lead to a higher (lower) fair value measurement. The discount rate is based on the Treasury rate adjusted by a margin. Increases (decreases) in the discount rates would lead 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. The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at December 31, 2012 (dollars in millions): Fair value at December 31, 2012 Valuation technique(s) Unobservable inputs Range (weighted average)Assets: Corporate securities (a)$248.3 Discounted cash flow analysis Discount margins 1.90% - 3.25% (2.78%)Asset-backed securities (b)33.3 Discounted cash flow analysis Discount margins 2.78% - 3.14% (2.99%)Collateralized debt obligations (c)331.4 Discounted cash flow analysis Recoveries 65% - 66% Constant prepayment rate 20% Discount margins .95% - 8.75% (2.02%) Annual default rate .95% - 5.54% (3.01%) Portfolio CCC % 1.18% - 21.56% (11.99%)Venture capital investments (d)2.8 Market multiples EBITDA multiple 6.8 Revenue multiple 1.5Other assets categorized as Level 3 (e)162.4 Unadjusted third-party price source Not applicable Not applicableTotal778.2 Liabilities: Interest sensitive products (f)739.5 Discounted projected embedded derivatives Projected portfolio yields 5.35% - 5.61% (5.55%) Discount rates 0.0 - 3.6% (1.4%) Surrender rates 4% - 43% (19%)________________________________(a)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 result in a significantly lower (higher) fair value measurement.(b)Asset-backed securities - The significant unobservable input used in the fair value measurement of our asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would result in a significantly lower (higher) fair value measurement.(c)Collateralized debt obligations - The significant unobservable inputs used in the fair value measurement of our collateralized debt obligations relate to collateral performance, including default rate, recoveries and constant prepayment rate, as well as discount margins of the underlying collateral. Significant increases (decreases) in default rate in isolation would result in a significantly lower (higher) fair value measurement. Generally, a significant increase (decrease) in the constant prepayment rate and recoveries in isolation would result in a significantly higher (lower) fair value measurement. Generally a significant increase (decrease) in discount margin in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the annual default rate is accompanied by a directionally similar change in the assumption used for discount margins and portfolio CCC % and a directionally opposite change in the assumption used for constant prepayment rate and recoveries. A tranche's payment priority and investment cost basis could alter generalized fair value outcomes.(d)Venture capital investments - The significant unobservable inputs used in the fair value measurement of our venture capital investments are the EBITDA multiple and revenue multiple. Generally, a significant increase (decrease) in the EBITDA or revenue multiples in isolation would result 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)Interest sensitive products - The significant unobservable inputs used in the fair value measurement of our interest sensitive products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would lead to a higher (lower) fair value measurement. The discount rate is based on the Treasury rate adjusted by a margin. Increases (decreases) in the discount rates would lead 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.
