Notes to Condensed Consolidated Financial Statements

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. The Company acquired Hardy Underwriting Bermuda Limited and its subsidiaries on July 2, 2012. Loews Corporation (Loews) owned approximately 90%of the outstanding common stock of CNAF as of September 30, 2013.

The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). 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, 2012, 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 September 30, 2013 and for the three and nine months ended September 30, 2013 and 2012 is unaudited. However, in the opinion of management, the interim data includes all adjustments, consisting of normal recurring accruals, 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. Intercompany amounts have been eliminated.

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 impact 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 and nine months ended September 30, 2013, approximately 515 thousand and 501 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 110 thousand and 115 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.

For the three and nine months ended September 30, 2012, approximately 450 thousand and 400 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 693 thousand and 740 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. At September 30, 2013 and December 31, 2012, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $723 million and $1,511 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 amount of pretax net realized gains on available-for-sale securities reclassified out of AOCI into earnings was $3 million and $15 million for the three and nine months ended September 30, 2013 and $12 million and $59 million for the three and nine months ended September 30, 2012.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2013 Securities in a Gross Unrealized Loss Position table above, are primarily attributable to broader economic conditions, changes in interest rates and credit spreads, market illiquidity and other market factors, but are not indicative of the ultimate collectibility of the current amortized cost of the securities. The investments with longer duration, primarily included within the states, municipalities and political subdivision asset category, were more significantly impacted by changes in market interest rates. The Company has no current intent to sell these

13

securities, 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 at September 30, 2013.

The following table summarizes the activity for the three and nine months ended September 30, 2013 and 2012 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at September 30, 2013 and 2012 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

Contractual Maturity

The following table summarizes available-for-sale fixed maturity securities by contractual maturity at September 30, 2013 and December 31, 2012. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid with or without call or prepayment penalties. Securities not due at a single date are allocated based on weighted average life.

Note D. Derivative Financial Instruments

Gross estimated fair values of derivative positions are presented in Other invested assets and Other liabilities on the Condensed Consolidated Balance Sheets. There would be no significant difference in the balance included in such accounts if the estimated fair values were presented net for the periods ended September 30, 2013 and December 31, 2012. The contractual or notional amounts for derivatives are used to calculate the exchange of contractual payments under the agreements and may not be representative of the potential for gain or loss on these instruments.

During the three and nine months ended September 30, 2013, new derivative transactions entered into totaled $224 million and $2,271 million in notional value while derivative termination activity totaled $221 million and $2,286 million. This activity was attributable to forward commitments for mortgage-backed securities, interest rate futures and foreign currency forwards. During the three and nine months ended September 30, 2012, new derivative transactions entered into totaled $472 million and $1,251 million in notional value while derivative termination activity totaled $488 million and $1,200 million. This activity was primarily attributable to interest rate futures, forward commitments for mortgage-backed securities and foreign currency forwards.

Note E. 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. Prices are determined by a dedicated group who ultimately report to the Company's Chief Financial Officer. This group is responsible for valuation policies and procedures. 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 independently validates detailed information regarding inputs and assumptions for individual securities and v) pricing validation, where prices received are compared to prices independently estimated by the Company.

Securities shown in the Level 3 tables on the previous pages may be transferred in or out of Level 3 based on the availability of observable market information used to determine the fair value of the security. The availability of observable market information varies based on market conditions and trading volume and may cause securities to move in and out of Level 3 from reporting period to reporting period. There were no transfers between Level 1 and Level 2during the three or nine months ended September 30, 2013 and $106 million of transfers from Level 2 to Level 1 during the three and nine months ended September 30, 2012. 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

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 include prices from recently executed transactions of similar securities, broker/dealer 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.

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. 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 tax-exempt auction rate certificates and private placement debt securities. Fair value of auction rate securities is determined utilizing a pricing model with three primary inputs. The interest rate and spread inputs are observable from like instruments while the expected call date assumption is unobservable due to the uncertain nature of principal prepayments prior to maturity and the credit spread adjustment that is security specific. Fair value of certain private placement debt securities 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.

23

Other Invested Assets

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities primarily include overseas deposits, which can be redeemed at net asset value in 90 days or less, and derivatives, primarily currency forwards valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, credit default 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.

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.

Separate Account Business

Separate account business includes fixed maturity securities, equities and short term investments. The valuation methodologies and inputs for these asset types have been described above.

Significant Unobservable Inputs

The table below presents 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.

Assets (In millions)	Fair Value at September 30, 2013		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	179	Discounted cash flow	Expected call date	2.1 - 5.3 years (3.8 years)
				Credit spread	1.92% - 26.24% (3.80%)
Equity securities	$	13	Market approach	Private offering price	$289.80 - $4,273.77 per share ($1,337.14 per share)
Life settlement contracts	$	90	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	69% - 883% (208.8%)

24

Assets (In millions)	Fair Value at December 31, 2012		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	121	Discounted cash flow	Expected call date	3.3 - 5.3 years (4.3 years)
				Credit spread adjustment	0.02% - 0.48% (0.17%)
	$	72	Market approach	Private offering price	$42.39 - $102.32 ($100.11)
Equity securities	$	34	Market approach	Private offering price	$4.54 - $3,842.00 per share ($571.17 per share)
Life settlement contracts	$	100	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	69% - 883% (208.9%)

For fixed maturity securities, an increase to the expected call date and 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 instrument assets and liabilities which are not measured at fair value on the Condensed Consolidated Balance Sheets are listed in the tables below.

Short term debt	13		—		13		—		13
Long term debt	2,557		—		3,016		—		3,016

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

The fair values of Notes receivable for the issuance of common stock were estimated using discounted cash flows utilizing interest rates currently offered for obligations securitized with similar collateral, adjusted for specific note receivable risk.

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.

Premium deposits and annuity contracts were valued based on cash surrender values or estimated fair values of policyholder liabilities, net of amounts ceded related to sold business.

25

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.

Note F. 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 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 $42 million and $146 million for the three and nine months ended September 30, 2013. Catastrophe losses in 2013 related primarily to U.S. storms. The Company reported catastrophe losses, net of reinsurance, of $27 million and $123 million for the three and nine months ended September 30, 2012.

Note J. 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, the maximum potential future lease payments and other related costs at September 30, 2013 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $90 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

In the course of selling business entities and assets to third parties, the Company has agreed 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 indemnification provisions generally survive for periods ranging from nine months following the applicable closing date to the expiration of the relevant statutes of limitation. As of September 30, 2013, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $723 million.

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 September 30, 2013, 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. These indemnification agreements survive until the applicable statutes of limitation expire or until the agreed upon contract terms expire.

As of September 30, 2013 and December 31, 2012, the Company had recorded liabilities of approximately $7 million related to indemnification agreements and management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.

35

Note K. Business Segments

The Company's core property and casualty commercial insurance operations are reported in three business segments: CNA Specialty, CNA Commercial and Hardy. 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 of the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2012. 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, 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 and 2) any cumulative effects of changes in accounting guidance. The calculation of net operating income excludes net realized investment gains or losses because net realized investment gains or 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 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 2012 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, 2012.

We utilize the net operating income financial measure to monitor our operations. Net operating income is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses and 2) any cumulative effects of changes in accounting guidance. See further discussion regarding how we manage our business in Note K to the Condensed Consolidated Financial Statements included under Part I, Item 1. In the evaluation of the results of our CNA Specialty, CNA Commercial and Hardy 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 impact of related acquisition expenses. Further information on our reserves is provided in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Three Month Comparison

Net income increased $51 million for the three months ended September 30, 2013 as compared with the same period in 2012. This increase was primarily due to higher net operating income.

Net realized investment gains decreased $2 million for the three months ended September 30, 2013 as compared with the same period in 2012. See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.

Net operating income increased $53 million for the three months ended September 30, 2013 as compared with the same period in 2012. Net operating income increased $66 million for our core segments, CNA Specialty, CNA Commercial and Hardy. This increase was primarily due to improved non-catastrophe current accident year underwriting results and higher favorable net prior year development, partially offset by higher catastrophe losses. Catastrophe losses were $28 million after-tax for the three months ended September 30, 2013 as compared with $18 million after-tax for the same period in 2012. Net operating results decreased $13 million for our non-core segments, driven by results in our Life & Group Non-Core segment. See the Life & Group Non-Core and Corporate & Other Non-Core sections of this MD&A for further discussion of our non-core results.

Favorable net prior year development of $76 million and $47 million was recorded for the three months ended September 30, 2013 and 2012 related to our CNA Specialty, CNA Commercial, Hardy and Corporate & Other Non-Core segments. Further information on net prior year development for the three months ended September 30, 2013 and 2012 is included in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Nine Month Comparison

Net income increased $79 million for the nine months ended September 30, 2013 as compared with the same period in 2012. This increase was due to higher net operating income, partially offset by decreased net realized investment gains.

Net realized investment gains decreased $31 million for the nine months ended September 30, 2013 as compared with the same period in 2012.

Net operating income increased $110 million for the nine months ended September 30, 2013 as compared with the same period in 2012. Net operating income increased $147 million for our core segments, CNA Specialty, CNA Commercial and Hardy. This increase was primarily due to improved non-catastrophe current accident year underwriting results, higher net investment income and a settlement benefit of $30 million after-tax related to workers’ compensation residual market litigation. These favorable items were partially offset by lower favorable net prior year development and increased catastrophe losses. Catastrophe losses were $96 million after-tax for the nine months ended September 30, 2013 as compared with $80 million after-tax for the same period in 2012. Net operating results decreased $37 million for our non-core segments, driven by results in our Life & Group Non-Core segment. See the Life & Group Non-Core and Corporate & Other Non-Core sections of this MD&A for further discussion of our non-core results.

Favorable net prior year development of $128 million and $165 million was recorded for the nine months ended September 30, 2013 and 2012 related to our CNA Specialty, CNA Commercial, Hardy and Corporate & Other Non-Core segments. Further information on net prior year development for the nine months ended September 30, 2013 and 2012 is included in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net earned premiums increased $291 million for the nine months ended September 30, 2013 as compared with the same period in 2012, driven by the acquisition of Hardy in July of 2012, a $74 million increase in CNA Specialty and a $57 million increase in CNA Commercial. 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 Products and Payout Annuity Contracts

• 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, 2012 for further information.

Catastrophe losses were $121 million, or 4.8 points of the loss ratio, for the nine months ended September 30, 2013, as compared with $115 million, or 4.7 points of the loss ratio, for the nine months ended September 30, 2012.

Unfavorable net prior year development of $5 million was recorded for the nine months ended September 30, 2013, compared to favorable net prior year development of $66 million for the nine months ended September 30, 2012. Further information on net prior year development is included in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Three Month Comparison

Net written premiums for Hardy increased $25 million for the three months ended September 30, 2013 as compared with the same period in 2012, driven by growth of non-marine property and a reduction in the amount of reinsurance purchased across several business units. In addition, a change in Hardy's share of the results of Syndicate 382 contributed to the growth in the period. Hardy retains 100% of the results for the 2013 year of account, while 25% of the capital for the 2012 year of account was provided by third parties. Net earned premiums increased $22 million as compared with the same period in 2012, consistent with increased net written premiums.

Hardy's average rate decreased 5% for the three months ended September 30, 2013, as compared with an increase of 1% for the three months ended September 30, 2012, for the policies that renewed in each period. Retention of 75% and 73% was achieved in each period.

Net income increased $11 million for the three months ended September 30, 2013 as compared with the same period in 2012. This increase was primarily due to higher net operating income.

Net operating income increased $9 million for the three months ended September 30, 2013 as compared with the same period in 2012, due to improved non-catastrophe underwriting results, partially offset by higher catastrophe losses. Pretax results in 2013 included $3 million of integration costs while results in 2012 included $6 million of non-run rate purchase accounting expenses. Further information on Hardy's amortization expense is included in Note I to the Condensed Consolidated Financial Statements included under Part I, Item 1.

The combined ratio improved 0.7 points for the three months ended September 30, 2013 as compared with the same period in 2012. The loss ratio increased 7.2 points, primarily due to higher catastrophe losses. The expense ratio improved 7.9 points, primarily due to the higher net earned premium base.

Favorable net prior year development of $5 million and $6 million was recorded for the three months ended September 30, 2013 and 2012. Further information on net prior year development is included in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Nine Month Results

The composition of net earned premiums for Hardy was $100 million for marine and aviation, $69 million for non-marine property, $30 million for specialty lines and $27 million for property treaty reinsurance. Premiums in 2012 relate to amounts written and earned after Hardy was acquired on July 2.

Hardy's average rate decreased 1% for the nine months ended September 30, 2013 for the policies that renewed in the period. Retention of 71% was achieved in the period.

51

Results in 2013 include favorable non-catastrophe underwriting results and pretax unfavorable net prior year development of $12 million. The unfavorable development primarily related to 2011 catastrophe events, including the Thailand floods and the New Zealand Lyttelton earthquake. The net prior year development includes $7 million of unfavorable premium development. Catastrophe losses were $5 million, or 2.0 points of the loss ratio, for the nine months ended September 30, 2013. No catastrophe losses were incurred for the nine months ended September 30, 2012.

The following table summarizes the gross and net carried reserves as of September 30, 2013 and December 31, 2012 for Hardy.

Three Month Comparison

Net earned premiums for Life & Group Non-Core decreased $1 million for the three months ended September 30, 2013 as compared with the same period in 2012. Net earned premiums relate primarily to the individual and group long term care businesses.

Net loss increased $11 million for the three months ended September 30, 2013 as compared with the same period in 2012. Results were affected by unfavorable morbidity in our long term care business, partially offset by the effect of rate increase actions and favorable persistency in that business.

Nine Month Comparison

Net earned premiums for Life & Group Non-Core decreased $2 million for the nine months ended September 30, 2013 as compared with the same period in 2012.

Net loss increased $33 million for the nine months ended September 30, 2013 as compared with the same period in 2012. This increase was primarily due to the same reasons discussed above in the three month comparison. Additionally, results in 2012 included a significant gain related to a benefit on a life settlement contract.

Three Month Comparison

Corporate & Other Non-Core primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP. Results for the three months ended September 30, 2013 were comparable to the prior year period.

Unfavorable net prior year development of $2 million was recorded in each of the three months ended September 30, 2013 and 2012.

Nine Month Comparison

Net loss decreased $1 million for the nine months ended September 30, 2013 as compared with the same period in 2012. Both periods benefited from releases of previously established allowances for uncollectible amounts arising from changes in estimates. For the nine months ended September 30, 2013, results were positively affected by $6 million related to the release of an allowance established for officer notes receivable. For the nine months ended September 30, 2012, results were positively affected by $13 million related to the release of an allowance established for uncollectible reinsurance receivables.

Unfavorable net prior year development of $1 million and $2 million was recorded for the nine months ended September 30, 2013 and 2012.

The following table summarizes the gross and net carried reserves as of September 30, 2013 and December 31, 2012 for Corporate & Other Non-Core.

Investment expense	(14		)	(13		)	(40		)	(42		)
Net investment income	$	597		$	601		$	1,808		$	1,719

Net investment income was $597 million for the third quarter of 2013, essentially unchanged from $601 million in the prior year quarter.

Net investment income for the nine months ended September 30, 2013 increased $89 million as compared with the same period in 2012. The increase was primarily driven by a significant increase in limited partnership investment results, partially offset by a decrease in fixed maturity securities income.

The fixed maturity investment portfolio provided a pretax effective income yield of 5.2% and 5.4% for the nine months ended September 30, 2013 and 2012. Tax-exempt municipal bonds generated $83 million and $223 million of net investment income for the three and nine months ended September 30, 2013 compared with $70 million and $205 million of net investment income for the same periods in 2012.

Net realized investment results decreased $2 million and $31 million for the three and nine months ended September 30, 2013 as compared with the same periods in 2012, driven by lower net realized investment gains on sales of securities, partially offset by lower OTTI losses recognized in earnings. Further information on our realized gains and losses, including our OTTI losses, is set forth in Note C to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Portfolio Quality

Our fixed maturity portfolio consists primarily of high quality bonds, 92% of which were rated as investment grade (rated BBB- or higher) at September 30, 2013 and December 31, 2012. 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 rating agencies, we formulate an internal rating. At September 30, 2013 and December 31, 2012, approximately 99% and 98% 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 summarizes the ratings of our fixed maturity portfolio at fair value.

Fixed Maturity Ratings

(In millions)	September 30, 2013		%		December 31, 2012		%
U.S. Government, Government agencies and Government-sponsored enterprises	$	3,506	9	%	$	4,540	11	%

Non-investment grade fixed maturity securities, as presented in the table below, include high-yield 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 bond portfolio was $3,259 million and $3,355 million at September 30, 2013 and December 31, 2012. The following table summarizes the ratings of this portfolio at fair value.

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 liabilities in the Life & Group Non-Core segment including annuities, structured settlements and long term care products.

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

Effective Durations

	September 30, 2013			December 31, 2012
(In millions)	Fair Value		Effective Duration (In years)	Fair Value		Effective Duration (In years)
Investments supporting Life & Group Non-Core	$	14,840	11.4	$	15,590	11.3
Other interest sensitive investments	27,803		4.4	28,855		3.9
Total	$	42,643	6.8	$	44,445	6.5

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, 2012.

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 the nine months ended September 30, 2013, net cash provided by operating activities was $921 million as compared with $993 million for the same period in 2012. Cash provided by operating activities in 2012 was favorably affected by a $75 million tax refund.

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

For the nine months ended September 30, 2013, net cash used by investing activities was $689 million as compared with $747 million for the same period in 2012. 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 nine months ended September 30, 2013, net cash used by financing activities was $200 million as compared with $195 million for the same period in 2012. Net cash used by financing activities in both periods was substantially related to the payment of dividends to common stockholders.

Common Stock Dividends

Dividends of $0.60 per share of our common stock were declared and paid during the nine months ended September 30, 2013. On October 25, 2013, our Board of Directors declared a quarterly dividend of $0.20 per share, payable November 26, 2013 to stockholders of record on November 12, 2013. 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 operations, investing activities 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.

During the nine months ended September 30, 2013, CCC paid dividends of $300 million to CNAF. As of September 30, 2013, CCC is able to pay approximately $550 million of dividends during the remainder of 2013 that would not be subject to the prior approval of the Illinois Department of Insurance.

In August 2013, CCC became a member of the Federal Home Loan Bank of Chicago (FHLBC). FHLBC membership provides participants with access to additional sources of liquidity through various programs and services. As a requirement of membership in the FHLBC, CCC acquired $16 million of FHLBC stock giving it access to approximately $330 million of additional liquidity. Any funding above this level would require the purchase of additional shares of FHLBC stock. As of September 30, 2013, CCC has no outstanding borrowings from the FHLBC.

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

Ratings

Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries are rated by major rating agencies and these ratings reflect the rating agency's opinion of

59

the insurance company's financial strength, operating performance, strategic position and ability to meet our obligations to policyholders. In June 2013, S&P upgraded our property and casualty insurance financial strength ratings to A with a stable outlook and upgraded the credit rating on the senior debt of CNAF to BBB. Further information on our ratings is included in the Management's Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012.

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 asbestos and environmental pollution 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 loss 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 consummation of contemplated transactions and the successful integration of acquired operations.

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 under priced 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, as well as restrictions on the ability or willingness of Loews to provide additional capital support to us; 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.

61

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 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 as well as the new federal financial regulatory reform of the insurance industry established by the Dodd-Frank Wall Street Reform and Consumer Protection Act;

• increased operating costs and underwriting losses arising from the Patient Protection and Affordable Care Act and the related amendments in the Health Care and Education Reconciliation Act, as well as health care reform proposals at the state level; 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 weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain 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 and the effect of the absence or insufficiency of applicable terrorism legislation on coverages;

• the unpredictability of the nature, targets, severity or frequency of potential terrorist events, as well as the uncertainty as to our ability to contain our terrorism exposure effectively; 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 nine months ended September 30, 2013. 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, 2012 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 September 30, 2013, 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 September 30, 2013.

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 September 30, 2013 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Commitments and Contingencies Disclosure [Abstract]

Commitments, Contingencies, and Guarantees

Note J. 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, the maximum potential future lease payments and other related costs at September 30, 2013 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $90 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

In the course of selling business entities and assets to third parties, the Company has agreed 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 indemnification provisions generally survive for periods ranging from nine months following the applicable closing date to the expiration of the relevant statutes of limitation. As of September 30, 2013, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $723 million.

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 September 30, 2013, 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. These indemnification agreements survive until the applicable statutes of limitation expire or until the agreed upon contract terms expire.

As of September 30, 2013 and December 31, 2012, the Company had recorded liabilities of approximately $7 million related to indemnification agreements and management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.

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. At September 30, 2013 and December 31, 2012, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $723 million and $1,511 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 summarize the estimated fair value and gross unrealized losses of available-for-sale 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.

The amount of pretax net realized gains on available-for-sale securities reclassified out of AOCI into earnings was $3 million and $15 million for the three and nine months ended September 30, 2013 and $12 million and $59 million for the three and nine months ended September 30, 2012.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2013 Securities in a Gross Unrealized Loss Position table above, are primarily attributable to broader economic conditions, changes in interest rates and credit spreads, market illiquidity and other market factors, but are not indicative of the ultimate collectibility of the current amortized cost of the securities. The investments with longer duration, primarily included within the states, municipalities and political subdivision asset category, were more significantly impacted by changes in market interest rates. The Company has no current intent to sell these securities, 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 at September 30, 2013.

The following table summarizes the activity for the three and nine months ended September 30, 2013 and 2012 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at September 30, 2013 and 2012 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

Segment Reporting [Abstract]

Business Segments

Note K. Business Segments

The Company's core property and casualty commercial insurance operations are reported in three business segments: CNA Specialty, CNA Commercial and Hardy. 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 of the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2012. 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, 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 and 2) any cumulative effects of changes in accounting guidance. The calculation of net operating income excludes net realized investment gains or losses because net realized investment gains or 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 operations and selected balance sheet items by segment are presented in the following tables.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General

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. The Company acquired Hardy Underwriting Bermuda Limited and its subsidiaries on July 2, 2012. Loews Corporation (Loews) owned approximately 90%of the outstanding common stock of CNAF as of September 30, 2013.

The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). 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, 2012, 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 September 30, 2013 and for the three and nine months ended September 30, 2013 and 2012 is unaudited. However, in the opinion of management, the interim data includes all adjustments, consisting of normal recurring accruals, 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. Intercompany amounts have been eliminated.

Summary of Derivative Instruments [Abstract]

Derivative Financial Instruments

Note D. Derivative Financial Instruments

Gross estimated fair values of derivative positions are presented in Other invested assets and Other liabilities on the Condensed Consolidated Balance Sheets. There would be no significant difference in the balance included in such accounts if the estimated fair values were presented net for the periods ended September 30, 2013 and December 31, 2012. The contractual or notional amounts for derivatives are used to calculate the exchange of contractual payments under the agreements and may not be representative of the potential for gain or loss on these instruments.

This activity was attributable to forward commitments for mortgage-backed securities, interest rate futures and foreign currency forwards. During the three and nine months ended September 30, 2012, new derivative transactions entered into totaled $472 million and $1,251 million in notional value while derivative termination activity totaled $488 million and $1,200 million. This activity was primarily attributable to interest rate futures, forward commitments for mortgage-backed securities and foreign currency forwards.

Earnings (loss) per share

Earnings Per Share [Abstract]

Earnings Per Share

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 impact 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 and nine months ended September 30, 2013, approximately 515 thousand and 501 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 110 thousand and 115 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.

For the three and nine months ended September 30, 2012, approximately 450 thousand and 400 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 693 thousand and 740 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.

Claim and Claim Adjustment Expense Reserves

Insurance Loss Reserves [Abstract]

Claim and Claim Adjustment Expense Reserves

Note F. 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 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.

Fair Value Disclosures [Abstract]

Fair Value

Note E. 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. Prices are determined by a dedicated group who ultimately report to the Company's Chief Financial Officer. This group is responsible for valuation policies and procedures. 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 independently validates detailed information regarding inputs and assumptions for individual securities and v) pricing validation, where prices received are compared to prices independently estimated by the Company.

Securities shown in the Level 3 tables on the previous pages may be transferred in or out of Level 3 based on the availability of observable market information used to determine the fair value of the security. The availability of observable market information varies based on market conditions and trading volume and may cause securities to move in and out of Level 3 from reporting period to reporting period. There were no transfers between Level 1 and Level 2during the three or nine months ended September 30, 2013 and $106 million of transfers from Level 2 to Level 1 during the three and nine months ended September 30, 2012. 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

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 include prices from recently executed transactions of similar securities, broker/dealer 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.

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. 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 tax-exempt auction rate certificates and private placement debt securities. Fair value of auction rate securities is determined utilizing a pricing model with three primary inputs. The interest rate and spread inputs are observable from like instruments while the expected call date assumption is unobservable due to the uncertain nature of principal prepayments prior to maturity and the credit spread adjustment that is security specific. Fair value of certain private placement debt securities 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.

Other Invested Assets

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities primarily include overseas deposits, which can be redeemed at net asset value in 90 days or less, and derivatives, primarily currency forwards valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, credit default 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.

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.

Separate Account Business

Separate account business includes fixed maturity securities, equities and short term investments. The valuation methodologies and inputs for these asset types have been described above.

Significant Unobservable Inputs

The table below presents 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.

Assets (In millions)	Fair Value at September 30, 2013		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	179	Discounted cash flow	Expected call date	2.1 - 5.3 years (3.8 years)
				Credit spread	1.92% - 26.24% (3.80%)
Equity securities	$	13	Market approach	Private offering price	$289.80 - $4,273.77 per share ($1,337.14 per share)
Life settlement contracts	$	90	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	69% - 883% (208.8%)

Assets (In millions)	Fair Value at December 31, 2012		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Fixed maturity securities	$	121	Discounted cash flow	Expected call date	3.3 - 5.3 years (4.3 years)
				Credit spread adjustment	0.02% - 0.48% (0.17%)
	$	72	Market approach	Private offering price	$42.39 - $102.32 ($100.11)
Equity securities	$	34	Market approach	Private offering price	$4.54 - $3,842.00 per share ($571.17 per share)
Life settlement contracts	$	100	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	69% - 883% (208.9%)

For fixed maturity securities, an increase to the expected call date and 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 instrument assets and liabilities which are not measured at fair value on the Condensed Consolidated Balance Sheets are listed in the tables below.

Short term debt	13		—		13		—		13
Long term debt	2,557		—		3,016		—		3,016

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

The fair values of Notes receivable for the issuance of common stock were estimated using discounted cash flows utilizing interest rates currently offered for obligations securitized with similar collateral, adjusted for specific note receivable risk.

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.

Premium deposits and annuity contracts were valued based on cash surrender values or estimated fair values of policyholder liabilities, net of amounts ceded related to sold business.

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.
