CNA Financial Corporation

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note A. General

Basis of Presentation

The Condensed Consolidated Financial Statements (Unaudited) include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of March 31, 2015.

The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. Certain financial information that is normally included in annual financial statements, including certain financial statement notes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in CNAF's Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2014, including the summary of significant accounting policies in Note A. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates.

The interim financial data as of March 31, 2015 and for the three months ended March 31, 2015 and 2014 is unaudited. However, in the opinion of management, the interim data includes all adjustments, including normal recurring adjustments, necessary for a fair statement of the Company's results for the interim periods. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

Sale of Continental Assurance Company (CAC)

On August 1, 2014, the Company completed the sale of the common stock of CAC, the Company's former life insurance subsidiary. In the first quarter of 2014, the Company recorded an after-tax impairment loss of $214 million related to the sale. The Company elected to include CAC cash flow activity in the comparative Condensed Consolidated Statement of Cash Flows. Further information on discontinued operations is provided in Note K to the Condensed Consolidated Financial Statements.

Note B. Earnings Per Share

Earnings per share is based on the weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the effect of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

For the three months ended March 31, 2015 and 2014, approximately 654 thousand and 660 thousand potential shares attributable to exercises under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 182 thousand and 110 thousand potential shares attributable to exercises under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.

The net unrealized gains on investments included in the tables above are recorded as a component of Accumulated other comprehensive income (AOCI). When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. As of March 31, 2015 and December 31, 2014, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $1,370 million and $1,288 million. To the extent that unrealized gains on fixed income securities supporting certain products within the Life & Group Non-Core segment would result in a premium deficiency if realized, a related decrease in Deferred acquisition costs and/or increase in Insurance reserves are recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (loss) (Shadow Adjustments).

Based on current facts and circumstances, the Company believes the unrealized losses presented in the March 31, 2015 table above, are not indicative of the ultimate collectibility of the current amortized cost of the securities, but rather are primarily attributable to changes in interest rates and credit spreads, market illiquidity and other factors. The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional OTTI losses to be recorded as of March 31, 2015.

The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of March 31, 2015 and 2014 for which a portion of an OTTI loss was recognized in Other comprehensive income.

Note D. Fair Value

Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable.

Level 1 - Quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are not observable.

Prices may fall within Level 1, 2 or 3 depending upon the methodologies and inputs used to estimate fair value for each specific security. In general the Company seeks to price securities using third-party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using methodologies and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company.

The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures include i) the review of pricing service or broker pricing methodologies, ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, iii) exception reporting, where changes in price, period-over-period, are reviewed and challenged with the pricing service or broker based on exception criteria, iv) deep dives, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities and v) pricing validation, where prices received are compared to prices independently estimated by the Company.

Securities shown on the previous pages may be transferred in or out of levels within the fair value hierarchy based on the availability of observable market information and quoted prices used to determine the fair value of the security. The availability of observable market information and quoted prices varies based on market conditions and trading volume. During the three months ended March 31, 2015 there were no transfers between Level 1 and Level 2. During the three months ended March 31, 2014 there were $23 million of transfers from Level 2 to Level 1 and $1 million from Level 1 to Level 2. The Company's policy is to recognize transfers between levels at the beginning of quarterly reporting periods.

Valuation Methodologies and Inputs

The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified.

Fixed Maturity Securities

Level 1 securities include exchange traded bonds, highly liquid U.S. and foreign government bonds and redeemable preferred stock, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using methodologies that model information generated by market transactions involving identical or comparable assets, as well as discounted cash flow methodologies. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are generally assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with inputs that are not market observable.

Equity Securities

Level 1 equity securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily non-redeemable preferred stocks and common stocks valued using pricing for similar securities, recently executed transactions, broker/dealer quotes and other pricing models utilizing market observable inputs. Level 3 securities are priced using internal models with inputs that are not market observable.

21

Derivative Financial Investments

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities primarily include the embedded derivative on funds withheld liability and currency forwards. The embedded derivative on funds withheld liability is valued using the change in fair value of the assets supporting the funds withheld payable, which are fixed maturity securities valued with observable inputs. Currency forwards are valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, equity warrants and options, are valued using inputs including broker/dealer quotes and are classified within Level 3 of the valuation hierarchy due to a lack of transparency as to whether these quotes are based on information that is observable in the marketplace.

Overseas Deposits

Overseas deposits, which can be redeemed at net asset value in 90 days or less, are classified as Level 2.

Short Term Investments

Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds and treasury bills. Level 2 primarily includes commercial paper, for which all inputs are market observable. Fixed maturity securities purchased within one year of maturity are classified consistent with fixed maturity securities discussed above. Short term investments as presented in the tables above differ from the amounts presented on the Condensed Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.

Life Settlement Contracts

The fair values of life settlement contracts are determined as the present value of the anticipated death benefits less anticipated premium payments based on contract terms that are distinct for each insured, as well as the Company's own assumptions for mortality, premium expense and the rate of return that a buyer would require on the contracts, as no comparable market pricing data is available.

Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurements of Level 3 assets. Valuations for assets and liabilities not presented in the table below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company.

March 31, 2015
(In millions)	Fair Value		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	102	Discounted cash flow	Credit spread	2% - 13% (3%)
Equity securities	13		Market approach	Private offering price	$10 - $4,400 per share ($682)
Life settlement contracts	79		Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	55% - 1676% (164%)

December 31, 2014
(In millions)	Fair Value		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	101	Discounted cash flow	Credit spread	2% - 13% (3%)
Equity securities	16		Market approach	Private offering price	$12 - $4,391 per share ($600)
Life settlement contracts	82		Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	55% - 1676% (163%)

22

For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement. For equity securities, an increase in the private offering price would result in a higher fair value measurement. For life settlement contracts, an increase in the discount rate risk premium or decrease in the mortality assumption would result in a lower fair value measurement.

Financial Assets and Liabilities Not Measured at Fair Value

The carrying amount and estimated fair value of the Company's financial assets and liabilities which are not measured at fair value on the Condensed Consolidated Balance Sheets are presented in the following tables.

March 31, 2015	Carrying Amount		Estimated Fair Value

Mortgage loans	588		—		—		608		608
Liabilities
Long term debt	$	2,559	$	—	$	2,883	$	—	$	2,883

The following methods and assumptions were used to estimate the fair value of these financial assets and liabilities.

The fair values of Mortgage loans were based on the present value of the expected future cash flows discounted at the current interest rate for origination of similar quality loans, adjusted for specific loan risk.

The Company's senior notes and debentures were valued based on observable market prices. The fair value for other debt was estimated using discounted cash flows based on current incremental borrowing rates for similar borrowing arrangements.

The carrying amounts reported on the Condensed Consolidated Balance Sheets for Cash, Short term investments not carried at fair value, Accrued investment income and certain Other assets and Other liabilities approximate fair value due to the short term nature of these items. These assets and liabilities are not listed in the tables above.

23

Note E. Claim and Claim Adjustment Expense Reserves

The Company's property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to such historical patterns as field reserving trends and claims settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions, economic conditions including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.

Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can all affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers' compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the Company's ultimate cost for insurance losses will not exceed current estimates.

Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in the Company's results of operations and/or equity. The Company reported catastrophe losses, net of reinsurance, of $29 million for the three months ended March 31, 2015. Catastrophe losses in 2015 related primarily to U.S. weather-related events. The Company reported catastrophe losses, net of reinsurance, of $74 million for the three months ended March 31, 2014.

The fourth quarter of 2014 asbestos and environmental pollution (A&EP) reserve review was not completed because additional information and analysis on inuring third-party reinsurance recoveries were needed to finalize the review. The review and analysis of this information continues, and the Company expects to complete the review in the second quarter of 2015. Given the significance of the information and analysis needed to finalize the remaining elements of the review, the Company is not able to estimate the impact, if any, of this uncertainty on the Company's Condensed Consolidated Financial Statements.

2015

Overall, unfavorable development for medical professional liability was primarily related to increased frequency in the Aging Services book for accident years 2013 and 2014, partially offset by better than expected severity in accident years 2010 and prior.

Favorable development for other coverages was primarily due to better than expected frequency in property coverages provided to Specialty customers in accident year 2014.

2014

Favorable development for other professional liability and management liability was related to better than expected loss emergence in accident years 2004 and prior.

2015

Favorable development for property and other was due to lower than expected loss emergence from 2014 catastrophe events.

2014

Unfavorable development for commercial auto was primarily related to higher than expected frequency in accident years 2012 and 2013 and higher than expected loss emergence in accident years 2010 and 2011.

Unfavorable development for workers' compensation was primarily due to the recognition of losses related to favorable premium development in accident year 2013.

Favorable development for property and other was primarily due to better than expected loss emergence in catastrophe losses in accident year 2013.

International

The following table presents further detail of the development recorded for the International segment.

Note H. Commitments, Contingencies and Guarantees

Commitments and Contingencies

The Company holds an investment in a real estate joint venture. In the normal course of business, the Company, on a joint and several basis with other unrelated insurance company shareholders, has committed to continue funding the operating deficits of this joint venture. Additionally, the Company and the other unrelated shareholders, on a joint and several basis, have guaranteed an operating lease for an office building, which expires in 2016. The guarantee of the operating lease is a parallel guarantee to the commitment to fund operating deficits; consequently, the separate guarantee to the lessor is not expected to be triggered as long as the joint venture continues to be funded by its shareholders which provide liquidity to make its annual lease payments.

In the event that the other parties to the joint venture are unable to meet their commitments in funding the operations of this joint venture, the Company would be required to assume the obligation for the entire office building operating lease. The Company does not believe it is likely that it will be required to do so.  However, as of March 31, 2015, the maximum potential future lease payments and other related costs that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $41 million. If the Company were required to assume the entire lease obligation, the Company would have the right to pursue reimbursement from the other shareholders and the right to all sublease revenues.

Guarantees

As of March 31, 2015 and December 31, 2014, the Company had recorded liabilities of approximately $5 million related to guarantee and indemnification agreements and management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.

In the course of selling business entities and assets to third parties, the Company agreed to guarantee the performance of certain obligations of a previously owned subsidiary and to indemnify purchasers for losses arising out of breaches of representation and warranties with respect to the business entities or assets being sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation.  Such guarantee and indemnification agreements in effect for sales of business entities, assets and third-party loans may include provisions that survive indefinitely. As of March 31, 2015, the aggregate amount related to quantifiable guarantees was $375 million and the aggregate amount related to indemnification agreements was $324 million. Should the Company be required to make payments under the guarantee, it would have the right to seek reimbursement in certain cases from an affiliate of a previously owned subsidiary.

In addition, the Company has agreed to provide indemnification to third-party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount. As of March 31, 2015, the Company had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. Certain provisions of the indemnification agreements survive indefinitely while others survive until the applicable statutes of limitation expire or until the agreed-upon contract terms expire.

In the normal course of business, the Company also provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities provided by a previously owned subsidiary, which are estimated to mature through 2120. The potential amount of future payments the Company could be required to pay under these guarantees was approximately $2.0 billion as of March 31, 2015. The Company does not believe a payable is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

Note J. Business Segments

The Company's core property and casualty commercial insurance operations are aggregated and reported in three business segments: Specialty, Commercial and International. The Company's non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core.

The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2014. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs and Goodwill are readily identifiable for all individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Realized investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense has been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.

In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio. Net operating income (loss), which is derived from certain income statement amounts, is used by management to monitor performance of the Company's insurance operations. The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk. Based on such analyses, the Company may recognize an OTTI loss on an investment security in accordance with its policy, or sell a security, which may produce realized gains and losses.

Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses, 2) income or loss from discontinued operations and 3) any cumulative effects of changes in accounting guidance. The calculation of net operating income excludes net realized investment gains (losses) because net realized investment gains (losses) are largely discretionary, except for some losses related to OTTI, and are generally driven by economic factors that are not necessarily consistent with key drivers of underwriting performance, and are therefore not considered an indication of trends in insurance operations.

The Company's results of continuing operations and selected balance sheet items by segment are presented in the following tables.

Item 2. Management's Discussion and Analysis (MD&A) of Financial Condition and Results of Operations

Overview

The following discussion highlights significant factors affecting the Company. References to “we,” “our,” “us” or like terms refer to the business of CNA. Based on 2013 statutory net written premiums, we are the eighth largest commercial insurance writer and the 13^th largest property and casualty insurance organization in the United States of America.

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements included under Part I, Item 1 of this Form 10-Q and Item 1A Risk Factors and Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2014.

We utilize the net operating income financial measure to monitor our operations. Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses, 2) income or loss from discontinued operations and 3) any cumulative effects of changes in accounting guidance. See further discussion regarding how we manage our business in Note J to the Condensed Consolidated Financial Statements included under Part I, Item 1. In the evaluation of the results of our Specialty, Commercial and International segments, we utilize the loss ratio, the expense ratio, the dividend ratio and the combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The expense ratio is the percentage of insurance underwriting and acquisition expenses, including the amortization of deferred acquisition costs, to net earned premiums. The dividend ratio is the ratio of policyholders' dividends incurred to net earned premiums. The combined ratio is the sum of the loss, expense and dividend ratios.

Changes in estimates of claim and allocated claim adjustment expense reserves and premium accruals, net of reinsurance, for prior years are defined as net prior year development within this MD&A. These changes can be favorable or unfavorable. Net prior year development does not include the effect of related acquisition expenses. Further information on our reserves is provided in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net income	$	233		$	13

Income from continuing operations increased $13 million for the three months ended March 31, 2015 as compared with the same period in 2014. The increase was due to higher net operating income, partially offset by lower Net realized investment gains, after tax.

Loss from discontinued operations, net of tax, for the three months ended March 31, 2014 includes an impairment loss of $214 million related to the sale of CAC.

Net realized investment gains, after tax, decreased $22 million for the three months ended March 31, 2015 as compared with the same period in 2014. See the Investments section of this MD&A for further discussion of Net investment income and Net realized investment results.

Net operating income increased $35 million for the three months ended March 31, 2015 as compared with the same period in 2014. Net operating income increased $45 million for our core segments. The increase was primarily driven by improved current accident year underwriting results as well as higher limited partnership income. Catastrophe losses were $19 million after tax for the three months ended March 31, 2015 as compared to $48 million after tax for the same period in 2014. See the Specialty, Commercial, and International sections of this MD&A for further discussion of our core results. Net operating loss for our non-core segments increased $10 million driven by results in our long term care business. See the Life & Group Non-Core and Corporate & Other Non-Core sections of this MD&A for further discussion of our non-core results.

Unfavorable net prior year development of $2 million was recorded for the three months ended March 31, 2015 as compared with favorable net prior year development of $6 million for the three months ended March 31, 2014 related to our Specialty, Commercial and International segments. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net earned premiums decreased $119 million for the three months ended March 31, 2015 as compared with the same period in 2014. See the Segment Results section of this MD&A for further discussion.

CRITICAL ACCOUNTING ESTIMATES

The preparation of the Condensed Consolidated Financial Statements (Unaudited) in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the amounts of revenues and expenses reported during the period. Actual results may differ from those estimates.

Our Condensed Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Condensed Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third-party professionals and various other assumptions that are believed to be reasonable under the known facts and circumstances.

The accounting estimates below are considered by us to be critical to an understanding of our Condensed Consolidated Financial Statements as their application places the most significant demands on our judgment.

• Insurance Reserves

• Reinsurance and Insurance Receivables

• Valuation of Investments and Impairment of Securities

• Long Term Care Policies

• Pension and Postretirement Benefit Obligations

• Income Taxes

Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from estimates and may have a material adverse impact on our results of operations or equity. See the Critical Accounting Estimates section of our Management's Discussion and Analysis of Financial Condition and Results of Operations included under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2014 for further information.

SEGMENT RESULTS

The following discusses the results of continuing operations for our operating segments.

Specialty

The following table presents the results of operations.

Expense	31.3			30.0
Dividend	0.2			0.2
Combined	94.6		%	94.1		%

Net written premiums for Specialty for the three months ended March 31, 2015 declined $15 million from the prior year period, primarily due to lower retention. The decline in net earned premiums was consistent with the trend in net written premiums.

Average rate increased 2% for the three months ended March 31, 2015, as compared with an increase of 4% for the three months ended March 31, 2014 for the policies that renewed in each period. Retention of 84% and 86% was achieved in each period.

The combined ratio increased 0.5 points for the three months ended March 31, 2015 as compared with the same period in 2014. The loss ratio improved 0.8 points due to an improved current accident year loss ratio, partially offset by less favorable net prior year development. The expense ratio increased 1.3 points for the three months ended March 31, 2015 as compared with the same period in 2014, primarily driven by increased underwriting expenses.

Favorable net prior year development of $4 million and $9 million was recorded for the three months ended March 31, 2015 and 2014. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Combined	103.3		%	111.3		%

Net written premiums for Commercial decreased $48 million for the three months ended March 31, 2015 as compared with the same period in 2014, primarily driven by underwriting actions taken in certain business classes and a lower level of new business, reflecting competitive market conditions, partially offset by positive rate and higher retention. Net earned premiums decreased $57 million for the three months ended March 31, 2015 as compared with the same period 2014, consistent with the trend in net written premiums.

Average rate increased 3% for the three months ended March 31, 2015, as compared with an increase of 6% for the three months ended March 31, 2014 for the policies that renewed in each period. Retention of 76% and 74% was achieved in each period.

Net income increased $39 million for the three months ended March 31, 2015 as compared with the same period in 2014. This increase was driven by higher net operating income.

Net operating income increased $46 million for the three months ended March 31, 2015 as compared with the same period in 2014, primarily due to improved underwriting results.

The combined ratio improved 8.0 points for the three months ended March 31, 2015 as compared with the same period in 2014. The loss ratio improved 10.2 points, primarily due to an improved current accident year loss ratio. Catastrophe losses were $19 million, or 2.8 points of the loss ratio for the three months ended March 31, 2015, as compared to $60 million, or 8.4 points of the loss ratio for the three months ended March 31, 2014. The expense ratio increased 2.1 points for the three months ended March 31, 2015 as compared with the same period in 2014, primarily due to the unfavorable effect of lower net earned premiums.

Favorable net prior year development of $6 million was recorded for the three months ended March 31, 2015. No net prior year development was recorded for three months ended March 31, 2014. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net written premiums for International decreased $35 million for the three months ended March 31, 2015 as compared with the same period in 2014. The decrease was primarily driven by the unfavorable effect of foreign currency exchange rates, unfavorable premium development at Hardy and the 2014 termination of a specialty product managing general underwriter relationship in Canada. Net earned premiums decreased $50 million for the three months ended March 31, 2015 as compared with the same period in 2014, consistent with the trend in net written premiums.

Average rate decreased 1% for the three months ended March 31, 2015, as compared with no change for the three months ended March 31, 2014 for the policies that renewed in each period. Retention of 76% and 82% was achieved in each period.

Net operating income decreased $7 million for the three months ended March 31, 2015 as compared with the same period in 2014, primarily due to the lower level of net earned premiums. Reinsurance commutations in the first quarter of 2014 reduced ceded losses from prior years and resulted in a release of the related allowance for uncollectible reinsurance.

The combined ratio increased 4.8 points for the three months ended March 31, 2015 as compared with the same period in 2014. The loss ratio increased 6.5 points, due to the unfavorable effect of net prior year development and a higher current accident year loss ratio. The prior year period benefited from the favorable impact of commutations. The expense ratio improved 1.7 points for the three months ended March 31, 2015 as compared with the same period in 2014 due to decreased expenses, partially offset by the unfavorable effect of lower net earned premiums.

Unfavorable net prior year development of $12 million and $3 million was recorded for the three months ended March 31, 2015 and 2014. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Life & Group Non-Core

The following table presents the results of operations.

Three months ended March 31

Net earned premiums	$	138		$	139
Net investment income	179			171
Net operating loss	(17		)	(2		)

Net income (loss)	(14		)	8

Net earned premiums for Life & Group Non-Core were largely consistent for the three months ended March 31, 2015 as compared with the same period in 2014, as the effect of policy lapses was substantially offset by rate increases.

Net results decreased $22 million in the three months ended March 31, 2015 as compared with the same period in 2014, primarily due to an increase in the net operating loss.

Net operating loss increased $15 million in the three months ended March 31, 2015 as compared with the same period in 2014. The increase was driven by unfavorable morbidity in our long term care business.

Portfolio Quality

Our fixed maturity portfolio consists primarily of high quality bonds, 93% of which were rated as investment grade (rated BBB- or higher) as of March 31, 2015 and December 31, 2014. The classification between investment grade and non-investment grade is based on a ratings methodology that takes into account ratings from Standard & Poor's (S&P) and Moody's Investors Service, Inc. (Moody's), in that order of preference. If a security is not rated by these agencies, we formulate an internal rating. As of March 31, 2015 and December 31, 2014, approximately 98% and 99% of the fixed maturity portfolio was rated by S&P or Moody's, or was issued or guaranteed by the U.S. Government, Government agencies or Government-sponsored enterprises.

The following table presents the ratings of our fixed maturity portfolio at fair value.

(In millions)	March 31, 2015		%		December 31, 2014		%
U.S. Government, Government agencies and Government-sponsored enterprises	$	3,829	9	%	$	3,882	10	%
AAA rated	2,762		7		2,850		7
AA and A rated	19,732		49		19,998		49
BBB rated	11,277		28		11,093		27
Non-investment grade	3,005		7		2,945		7
Total	$	40,605	100	%	$	40,768	100	%

Non-investment grade fixed maturity securities, as presented in the table below, include securities rated below BBB- by bond rating agencies and other unrated securities that, according to our analysis, are below investment grade. Non-investment grade securities generally involve a greater degree of risk than investment grade securities. The amortized cost of our non-investment grade fixed maturity securities was $2,862 million and $2,828 million as of March 31, 2015 and December 31, 2014. The following table presents the ratings of these securities at fair value.

(In millions)	March 31, 2015		%		December 31, 2014		%

Duration

A primary objective in the management of the investment portfolio is to optimize return relative to corresponding liabilities and respective liquidity needs. Our views on the current interest rate environment, tax regulations, asset class valuations, specific security issuer and broader industry segment conditions and the domestic and global economic conditions, are some of the factors that enter into an investment decision. We also continually monitor exposure to issuers of securities held and broader industry sector exposures and may from time to time adjust such exposures based on our views of a specific issuer or industry sector.

A further consideration in the management of the investment portfolio is the characteristics of the corresponding liabilities and the ability to align the duration of the portfolio to those liabilities and to meet future liquidity needs, minimize interest rate risk and maintain a level of income sufficient to support the underlying insurance liabilities. For portfolios where future liability cash flows are determinable and typically long term in nature, we segregate investments for asset/liability management purposes. The segregated investments support the long term care and structured settlement liabilities in the Life & Group Non-Core segment.

The effective durations of fixed maturity securities and short term investments are presented in the following table. Amounts presented are net of payable and receivable amounts for securities purchased and sold, but not yet settled.

	March 31, 2015			December 31, 2014
(In millions)	Fair Value		Effective Duration (In years)	Fair Value		Effective Duration (In years)
Investments supporting Life & Group Non-Core	$	14,928	10.3	$	14,668	10.5
Other interest sensitive investments	27,126		4.1	27,748		4.0
Total	$	42,054	6.3	$	42,416	6.3

The investment portfolio is periodically analyzed for changes in duration and related price risk. Additionally, we periodically review the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes. A summary of these risks and specific analysis on changes is included in the Quantitative and Qualitative Disclosures About Market Risk in Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2014.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Our primary operating cash flow sources are premiums and investment income from our insurance subsidiaries. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.

For three months ended March 31, 2015, net cash provided by operating activities was $94 million as compared with $168 million for the same period in 2014. Cash provided by operating activities reflected decreased receipts relating to returns on limited partnerships, partially offset by lower net claim payments. Additionally, cash receipts and cash payments resulting from purchases and sales of trading securities are reported as cash flows related to operating activities.

Cash flows from investing activities include the purchase and disposition of available-for-sale financial instruments and may include the purchase and sale of businesses, land, buildings, equipment and other assets not generally held for resale.

Net cash provided by investing activities was $526 million for the three months ended March 31, 2015, as compared with net cash used of $354 million for the same period in 2014. The cash flow from investing activities is affected by various factors such as the anticipated payment of claims, financing activity, asset/liability management and individual security buy and sell decisions made in the normal course of portfolio management.

Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, outflows for stockholder dividends or repayment of debt and outlays to reacquire equity instruments. For the three months ended March 31, 2015, net cash used by financing activities was $603 million as compared with net cash provided of $210 million for the same period in 2014. Cash used by financing activities reflected an increased special stockholder dividend as compared to the same period in 2014. Additionally, in the first quarter of 2014, we issued $550 million of senior notes.

Common Stock Dividends

A quarterly dividend of $0.25 per share and a special dividend of $2.00 per share of our common stock were declared and paid in the first quarter of 2015. On May 1, 2015, our Board of Directors declared a quarterly dividend of $0.25 per share, payable June 3, 2015 to stockholders of record on May 18, 2015. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs and regulatory constraints.

Liquidity

We believe that our present cash flows from operating, investing and financing activities are sufficient to fund our current and expected working capital and debt obligation needs and we do not expect this to change in the near term. There are currently no amounts outstanding under our $250 million senior unsecured revolving credit facility and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago.

Dividends from Continental Casualty Company (CCC) are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by Illinois Department of Insurance (the Department), are determined based on statutory net income and surplus as well as timing of dividends paid in the preceding twelve months. Ordinary dividends may only be paid from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. During the first quarter of 2015, CCC paid a dividend of $600 million to its parent. As of March 31, 2015, CCC is able to pay approximately $216 million of dividends that would not be subject to the prior approval of the Department.

We have an effective automatic shelf registration statement under which we may issue debt, equity or hybrid securities.

FORWARD-LOOKING STATEMENTS

This report contains a number of forward-looking statements which relate to anticipated future events rather than actual present conditions or historical events. These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and generally include words such as “believes,” “expects,” “intends,” “anticipates,” “estimates,” and similar expressions. Forward-looking statements in this report include any and all statements regarding expected developments in our insurance business, including losses and loss reserves for A&EP and other mass tort claims which are more uncertain, and therefore more difficult to estimate than loss reserves respecting traditional property and casualty exposures; the impact of routine ongoing insurance reserve reviews we are conducting; our expectations concerning our revenues, earnings, expenses and investment activities; volatility in investment returns; expected cost savings and other results from our expense reduction activities; and our proposed actions in response to trends in our business. Forward-looking statements, by their nature, are subject to a variety of inherent risks and uncertainties that could cause actual results to differ materially from the results projected in the forward-looking statement. We cannot control many of these risks and uncertainties. These risks and uncertainties include, but are not limited to, the following:

Company-Specific Factors

• the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of our Annual Report on Form 10-K, including the sufficiency of the reserves and the possibility for future increases, which would be reflected in the results of operations in the period that the need for such adjustment is determined;

• the risk that the other parties to the transaction in which, subject to certain limitations, we ceded our legacy A&EP liabilities will not fully perform their obligations to CNA, the uncertainty in estimating loss reserves for A&EP liabilities and the possible continued exposure of CNA to liabilities for A&EP claims that are not covered under the terms of the transaction;

• the performance of reinsurance companies under reinsurance contracts with us; and

• the risks and uncertainties associated with potential acquisitions and divestitures, including the consummation of such transactions, the successful integration of acquired operations and the potential for subsequent impairment of goodwill or intangible assets.

Industry and General Market Factors

• the impact of competitive products, policies and pricing and the competitive environment in which we operate, including changes in our book of business;

• product and policy availability and demand and market responses, including the level of ability to obtain rate increases and decline or non-renew underpriced accounts, to achieve premium targets and profitability and to realize growth and retention estimates;

• general economic and business conditions, including recessionary conditions that may decrease the size and number of our insurance customers and create additional losses to our lines of business, especially those that provide management and professional liability insurance, as well as surety bonds, to businesses engaged in real estate, financial services and professional services and inflationary pressures on medical care costs, construction costs and other economic sectors that increase the severity of claims;

• conditions in the capital and credit markets, including continuing uncertainty and instability in these markets, as well as the overall economy, and their impact on the returns, types, liquidity and valuation of our investments;

• conditions in the capital and credit markets that may limit our ability to raise significant amounts of capital on favorable terms; and

• the possibility of changes in our ratings by ratings agencies, including the inability to access certain markets or distribution channels and the required collateralization of future payment obligations as a result of such changes, and changes in rating agency policies and practices.

47

Regulatory Factors

• regulatory initiatives and compliance with governmental regulations, judicial interpretations within the regulatory framework, including interpretation of policy provisions, decisions regarding coverage and theories of liability, trends in litigation and the outcome of any litigation involving us and rulings and changes in tax laws and regulations;

• regulatory limitations, impositions and restrictions upon us, including with respect to our ability to increase premium rates, and the effects of assessments and other surcharges for guaranty funds and second-injury funds, other mandatory pooling arrangements and future assessments levied on insurance companies; and

• regulatory limitations and restrictions, including limitations upon our ability to receive dividends from our insurance subsidiaries, imposed by regulatory authorities, including regulatory capital adequacy standards.

Impact of Catastrophic Events and Related Developments

• weather and other natural physical events, including the severity and frequency of storms, hail, snowfall and other winter conditions, natural disasters such as hurricanes and earthquakes, as well as climate change, including effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow;

• regulatory requirements imposed by coastal state regulators in the wake of hurricanes or other natural disasters, including limitations on the ability to exit markets or to non-renew, cancel or change terms and conditions in policies, as well as mandatory assessments to fund any shortfalls arising from the inability of quasi-governmental insurers to pay claims;

• man-made disasters, including the possible occurrence of terrorist attacks, the unpredictability of the nature, targets, severity or frequency of such events and the effect of the absence or insufficiency of applicable terrorism legislation on coverages; and

• the occurrence of epidemics.

Our forward-looking statements speak only as of the date on which they are made and we do not undertake any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date of the statement, even if our expectations or any related events or circumstances change.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There were no material changes in our market risk components for the three months ended March 31, 2015. See the Quantitative and Qualitative Disclosures About Market Risk included in Item 7A on our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2014 for further information. Additional information related to portfolio duration is discussed in the Investments section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part I, Item 2.

Item 4. Controls and Procedures

The Company maintains a system of disclosure controls and procedures which are designed to ensure that information required to be disclosed by the Company in reports that it files or submits to the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including this report, is recorded, processed, summarized and reported on a timely basis. These disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to the Company's management on a timely basis to allow decisions regarding required disclosure.

As of March 31, 2015, the Company's management, including the Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective as of March 31, 2015.

There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2015 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Note A. General

Basis of Presentation

The Condensed Consolidated Financial Statements (Unaudited) include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of March 31, 2015.

The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. Certain financial information that is normally included in annual financial statements, including certain financial statement notes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in CNAF's Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2014, including the summary of significant accounting policies in Note A. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates.

The interim financial data as of March 31, 2015 and for the three months ended March 31, 2015 and 2014 is unaudited. However, in the opinion of management, the interim data includes all adjustments, including normal recurring adjustments, necessary for a fair statement of the Company's results for the interim periods. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

Sale of Continental Assurance Company (CAC)

On August 1, 2014, the Company completed the sale of the common stock of CAC, the Company's former life insurance subsidiary. In the first quarter of 2014, the Company recorded an after-tax impairment loss of $214 million related to the sale. The Company elected to include CAC cash flow activity in the comparative Condensed Consolidated Statement of Cash Flows. Further information on discontinued operations is provided in Note K to the Condensed Consolidated Financial Statements.

Segment Reporting [Abstract]

Business Segments

Note J. Business Segments

The Company's core property and casualty commercial insurance operations are aggregated and reported in three business segments: Specialty, Commercial and International. The Company's non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core.

The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2014. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs and Goodwill are readily identifiable for all individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Realized investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense has been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.

In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio. Net operating income (loss), which is derived from certain income statement amounts, is used by management to monitor performance of the Company's insurance operations. The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk. Based on such analyses, the Company may recognize an OTTI loss on an investment security in accordance with its policy, or sell a security, which may produce realized gains and losses.

Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses, 2) income or loss from discontinued operations and 3) any cumulative effects of changes in accounting guidance. The calculation of net operating income excludes net realized investment gains (losses) because net realized investment gains (losses) are largely discretionary, except for some losses related to OTTI, and are generally driven by economic factors that are not necessarily consistent with key drivers of underwriting performance, and are therefore not considered an indication of trends in insurance operations.

The Company's results of continuing operations and selected balance sheet items by segment are presented in the following tables.

Fair Value Disclosures [Abstract]

Fair Value

Note D. Fair Value

Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable.

Level 1 - Quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are not observable.

Prices may fall within Level 1, 2 or 3 depending upon the methodologies and inputs used to estimate fair value for each specific security. In general the Company seeks to price securities using third-party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using methodologies and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company.

The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures include i) the review of pricing service or broker pricing methodologies, ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, iii) exception reporting, where changes in price, period-over-period, are reviewed and challenged with the pricing service or broker based on exception criteria, iv) deep dives, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities and v) pricing validation, where prices received are compared to prices independently estimated by the Company.

Securities shown on the previous pages may be transferred in or out of levels within the fair value hierarchy based on the availability of observable market information and quoted prices used to determine the fair value of the security. The availability of observable market information and quoted prices varies based on market conditions and trading volume. During the three months ended March 31, 2015 there were no transfers between Level 1 and Level 2. During the three months ended March 31, 2014 there were $23 million of transfers from Level 2 to Level 1 and $1 million from Level 1 to Level 2. The Company's policy is to recognize transfers between levels at the beginning of quarterly reporting periods.

Valuation Methodologies and Inputs

The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified.

Fixed Maturity Securities

Level 1 securities include exchange traded bonds, highly liquid U.S. and foreign government bonds and redeemable preferred stock, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using methodologies that model information generated by market transactions involving identical or comparable assets, as well as discounted cash flow methodologies. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are generally assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with inputs that are not market observable.

Equity Securities

Level 1 equity securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily non-redeemable preferred stocks and common stocks valued using pricing for similar securities, recently executed transactions, broker/dealer quotes and other pricing models utilizing market observable inputs. Level 3 securities are priced using internal models with inputs that are not market observable.

Derivative Financial Investments

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities primarily include the embedded derivative on funds withheld liability and currency forwards. The embedded derivative on funds withheld liability is valued using the change in fair value of the assets supporting the funds withheld payable, which are fixed maturity securities valued with observable inputs. Currency forwards are valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, equity warrants and options, are valued using inputs including broker/dealer quotes and are classified within Level 3 of the valuation hierarchy due to a lack of transparency as to whether these quotes are based on information that is observable in the marketplace.

Overseas Deposits

Overseas deposits, which can be redeemed at net asset value in 90 days or less, are classified as Level 2.

Short Term Investments

Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds and treasury bills. Level 2 primarily includes commercial paper, for which all inputs are market observable. Fixed maturity securities purchased within one year of maturity are classified consistent with fixed maturity securities discussed above. Short term investments as presented in the tables above differ from the amounts presented on the Condensed Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.

Life Settlement Contracts

The fair values of life settlement contracts are determined as the present value of the anticipated death benefits less anticipated premium payments based on contract terms that are distinct for each insured, as well as the Company's own assumptions for mortality, premium expense and the rate of return that a buyer would require on the contracts, as no comparable market pricing data is available.

Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurements of Level 3 assets. Valuations for assets and liabilities not presented in the table below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company.

March 31, 2015
(In millions)	Fair Value		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	102	Discounted cash flow	Credit spread	2% - 13% (3%)
Equity securities	13		Market approach	Private offering price	$10 - $4,400 per share ($682)
Life settlement contracts	79		Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	55% - 1676% (164%)

December 31, 2014
(In millions)	Fair Value		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	101	Discounted cash flow	Credit spread	2% - 13% (3%)
Equity securities	16		Market approach	Private offering price	$12 - $4,391 per share ($600)
Life settlement contracts	82		Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	55% - 1676% (163%)

For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement. For equity securities, an increase in the private offering price would result in a higher fair value measurement. For life settlement contracts, an increase in the discount rate risk premium or decrease in the mortality assumption would result in a lower fair value measurement.

Financial Assets and Liabilities Not Measured at Fair Value

The carrying amount and estimated fair value of the Company's financial assets and liabilities which are not measured at fair value on the Condensed Consolidated Balance Sheets are presented in the following tables.

March 31, 2015	Carrying Amount		Estimated Fair Value

Notes receivable for the issuance of common stock	$	1	$	—	$	—	$	1	$	1

Mortgage loans	588		—		—		608		608
Liabilities
Long term debt	$	2,559	$	—	$	2,883	$	—	$	2,883

The following methods and assumptions were used to estimate the fair value of these financial assets and liabilities.

The fair values of Mortgage loans were based on the present value of the expected future cash flows discounted at the current interest rate for origination of similar quality loans, adjusted for specific loan risk.

The Company's senior notes and debentures were valued based on observable market prices. The fair value for other debt was estimated using discounted cash flows based on current incremental borrowing rates for similar borrowing arrangements.

The carrying amounts reported on the Condensed Consolidated Balance Sheets for Cash, Short term investments not carried at fair value, Accrued investment income and certain Other assets and Other liabilities approximate fair value due to the short term nature of these items. These assets and liabilities are not listed in the tables above.

The net unrealized gains on investments included in the tables above are recorded as a component of Accumulated other comprehensive income (AOCI). When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. As of March 31, 2015 and December 31, 2014, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $1,370 million and $1,288 million. To the extent that unrealized gains on fixed income securities supporting certain products within the Life & Group Non-Core segment would result in a premium deficiency if realized, a related decrease in Deferred acquisition costs and/or increase in Insurance reserves are recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (loss) (Shadow Adjustments).

The following tables present the estimated fair value and gross unrealized losses of fixed maturity and equity securities in a gross unrealized loss position by the length of time in which the securities have continuously been in that position.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the March 31, 2015 table above, are not indicative of the ultimate collectibility of the current amortized cost of the securities, but rather are primarily attributable to changes in interest rates and credit spreads, market illiquidity and other factors. The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional OTTI losses to be recorded as of March 31, 2015.

The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of March 31, 2015 and 2014 for which a portion of an OTTI loss was recognized in Other comprehensive income.

Claim and Claim Adjustment Expense Reserves

Claim and Claim Adjustment Expense Reserves [Abstract]

Claim and Claim Adjustment Expense Reserves

Note E. Claim and Claim Adjustment Expense Reserves

The Company's property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to such historical patterns as field reserving trends and claims settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions, economic conditions including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.

Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can all affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers' compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the Company's ultimate cost for insurance losses will not exceed current estimates.

Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in the Company's results of operations and/or equity. The Company reported catastrophe losses, net of reinsurance, of $29 million for the three months ended March 31, 2015. Catastrophe losses in 2015 related primarily to U.S. weather-related events. The Company reported catastrophe losses, net of reinsurance, of $74 million for the three months ended March 31, 2014.

The fourth quarter of 2014 asbestos and environmental pollution (A&EP) reserve review was not completed because additional information and analysis on inuring third-party reinsurance recoveries were needed to finalize the review. The review and analysis of this information continues, and the Company expects to complete the review in the second quarter of 2015. Given the significance of the information and analysis needed to finalize the remaining elements of the review, the Company is not able to estimate the impact, if any, of this uncertainty on the Company's Condensed Consolidated Financial Statements.

Overall, unfavorable development for medical professional liability was primarily related to increased frequency in the Aging Services book for accident years 2013 and 2014, partially offset by better than expected severity in accident years 2010 and prior.

Favorable development for other coverages was primarily due to better than expected frequency in property coverages provided to Specialty customers in accident year 2014.

2014

Favorable development for other professional liability and management liability was related to better than expected loss emergence in accident years 2004 and prior.

Commercial

Commitments, Contingencies, and Guarantees

Note H. Commitments, Contingencies and Guarantees

Commitments and Contingencies

The Company holds an investment in a real estate joint venture. In the normal course of business, the Company, on a joint and several basis with other unrelated insurance company shareholders, has committed to continue funding the operating deficits of this joint venture. Additionally, the Company and the other unrelated shareholders, on a joint and several basis, have guaranteed an operating lease for an office building, which expires in 2016. The guarantee of the operating lease is a parallel guarantee to the commitment to fund operating deficits; consequently, the separate guarantee to the lessor is not expected to be triggered as long as the joint venture continues to be funded by its shareholders which provide liquidity to make its annual lease payments.

In the event that the other parties to the joint venture are unable to meet their commitments in funding the operations of this joint venture, the Company would be required to assume the obligation for the entire office building operating lease. The Company does not believe it is likely that it will be required to do so.  However, as of March 31, 2015, the maximum potential future lease payments and other related costs that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $41 million. If the Company were required to assume the entire lease obligation, the Company would have the right to pursue reimbursement from the other shareholders and the right to all sublease revenues.

Guarantees

As of March 31, 2015 and December 31, 2014, the Company had recorded liabilities of approximately $5 million related to guarantee and indemnification agreements and management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.

In the course of selling business entities and assets to third parties, the Company agreed to guarantee the performance of certain obligations of a previously owned subsidiary and to indemnify purchasers for losses arising out of breaches of representation and warranties with respect to the business entities or assets being sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation.  Such guarantee and indemnification agreements in effect for sales of business entities, assets and third-party loans may include provisions that survive indefinitely. As of March 31, 2015, the aggregate amount related to quantifiable guarantees was $375 million and the aggregate amount related to indemnification agreements was $324 million. Should the Company be required to make payments under the guarantee, it would have the right to seek reimbursement in certain cases from an affiliate of a previously owned subsidiary.

In addition, the Company has agreed to provide indemnification to third-party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount. As of March 31, 2015, the Company had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. Certain provisions of the indemnification agreements survive indefinitely while others survive until the applicable statutes of limitation expire or until the agreed-upon contract terms expire.

In the normal course of business, the Company also provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities provided by a previously owned subsidiary, which are estimated to mature through 2120. The potential amount of future payments the Company could be required to pay under these guarantees was approximately $2.0 billion as of March 31, 2015. The Company does not believe a payable is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Note B. Earnings Per Share

Earnings per share is based on the weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the effect of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

For the three months ended March 31, 2015 and 2014, approximately 654 thousand and 660 thousand potential shares attributable to exercises under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 182 thousand and 110 thousand potential shares attributable to exercises under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.
