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 controlled subsidiaries. Collectively, CNAF and its controlled subsidiaries are referred to as CNA or the Company. CNA’s property and casualty and remaining life and group insurance operations are primarily conducted by Continental Casualty Company (CCC), The Continental Insurance Company, Western Surety Company, and Continental Assurance Corporation. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of September 30, 2012.

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 (SEC) for the year ended December 31, 2011, 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, 2012 and for the three and nine months ended September 30, 2012 and 2011 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.

Noncontrolling Interests

Net income attributable to noncontrolling interests for the three and nine months ended September 30, 2011 represented the noncontrolling interests in CNA Surety Corporation (Surety) and First Insurance Company of Hawaii (FICOH). On June 10, 2011, CNA completed the acquisition of the noncontrolling interest of Surety and on November 29, 2011, CNA completed the sale of its 50% ownership interest in FICOH.

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

In October 2010, the Financial Accounting Standards Board issued updated accounting guidance which limits the capitalization of costs incurred to acquire or renew insurance contracts to those that are incremental direct costs of successful contract acquisitions. The previous guidance allowed the capitalization of acquisition costs that vary with and are primarily related to the acquisition of new and renewal insurance contracts, whether the costs related to successful or unsuccessful efforts.

As of January 1, 2012, the Company adopted the updated accounting guidance prospectively as of January 1, 2004, the earliest date practicable. Due to the lack of available historical data related to certain accident and health contracts issued prior to January 1, 2004, a full retrospective application of the change in accounting guidance was impracticable. Acquisition costs capitalized prior to January 1, 2004 will continue to be accounted for under the previous accounting guidance and will be amortized over the premium-paying period of the related policies using assumptions consistent with those used for computing future policy benefit reserves for such contracts.

For the three and nine months ended September 30, 2012, the adoption of the new accounting guidance resulted in no impact and a $3 million decrease in Net income attributable to CNA and no impact and a $0.01 decrease in Basic and Diluted earnings per share attributable to CNA common stockholders.

The Company has adjusted its previously reported financial information included herein to reflect the change in accounting guidance for deferred acquisition costs. The impacts of adopting the new accounting standard on the

10

Company's Condensed Consolidated Balance Sheet as of December 31, 2011 were a $106 million decrease in Deferred acquisition costs and a $37 million increase in Deferred income taxes. The impacts to Accumulated other comprehensive income (AOCI) and Additional paid-in capital were the result of the indirect effects of the Company's adoption of this guidance on Shadow Adjustments, as further discussed in Note D, and the Company's acquisition of the noncontrolling interest of Surety as discussed above.

The impacts on the Company's Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2011 were a $59 million and $171 million decrease in Amortization of deferred acquisition costs, a $59 million and $178 million increase in Other operating expenses, a $1 million and $2 million decrease in Income tax expense, and a $1 million increase and no impact in Net income attributable to noncontrolling interests, resulting in no impact and a $5 million decrease in Net income attributable to CNA, and no impact and a $0.02 decrease in Basic and Diluted earnings per share attributable to CNA common stockholders. There were no changes to net cash flows from operating, investing or financing activities for the comparative periods presented as a result of the adoption of the new accounting standard.

Note B. Hardy

On July 2, 2012, the Company completed the previously announced acquisition of all outstanding shares of Hardy Underwriting Bermuda Limited and its subsidiaries (Hardy), a specialized Lloyd's of London (Lloyd's) underwriter. Through Lloyd's Syndicate 382, Hardy underwrites primarily short-tail exposures in marine and aviation, non-marine property, specialty lines and property treaty reinsurance. The acquisition of Hardy aligns with the Company's specialized underwriting focus and will be a key platform for expanding the Company's global business through the Lloyd's marketplace. The results of Hardy for the period from July 2, 2012 to September 30, 2012 are included in the results of our core property and casualty insurance operations as a separate segment.

For the year ended December 31, 2011, Hardy reported gross written premiums of $430 million and recorded a loss of $55 million in its group consolidated financial statements prepared in accordance with International Financial Reporting Standards.

The purchase price for Hardy was $231 million. Acquisition related expenses of $4 million were incurred during the nine months ended September 30, 2012, including investment advisory, legal and other expenses, and were recorded in the Corporate and Other Non-Core segment.

The fair value of the assets acquired and the liabilities assumed as a result of the acquisition of Hardy were as follows:

(In millions)	Acquisition Date
	July 2, 2012
Investments:
Fixed maturity securities	$	117
Short term investments	255
Total investments	372
Cash	34
Reinsurance receivables	252
Insurance receivables	222
Accrued investment income	2
Property and equipment	4
Goodwill and other intangible assets	171
Other assets	109
Total assets acquired	$	1,166
Claim and claim adjustment expenses	$	500
Unearned premiums	249
Long term debt	30
Other liabilities	156
Total liabilities assumed	$	935

The intangible assets acquired are presented in the following table.

(In millions)	Amount		Economic Useful Life
Syndicate capacity	$	55	Indefinite
Total indefinite-lived intangible assets	55
Value of business acquired	60		1 - 4 years
Trade name	8		8 years
Distribution channel	13		15 years
Total finite-lived intangible assets	81
Total intangible assets as of the acquisition date	$	136

For the three months ended September 30, 2012, amortization expense of $18 million was included in Amortization of deferred acquisition costs and $6 million was included in Other operating expenses in the Statement of Operations for the Hardy segment. Estimated future amortization expense for these intangible assets is $19 million in the fourth quarter of 2012, $21 million in 2013, $4 million in 2014, $1 million in 2015 and $2 million in both 2016 and 2017.

The acquisition resulted in goodwill of $35 million which was recorded in the Hardy segment. The recognized goodwill is based on the Company's expected growth and profitability of Hardy. The goodwill is not deductible for tax purposes.

Lloyd's requires syndicate capital providers to provide funds at Lloyd's (FAL) which is available to Lloyd's should funds in the Lloyd's premium trust fund be insufficient to cover obligations. At September 30, 2012, the Company had a deposit of $66 million of short duration U.S. Treasury securities in a Lloyd's custody account related to the FAL. Although the Company still owns these securities, these securities are controlled by Lloyd's and are therefore restricted. Additionally, cash and securities with a carrying value of approximately $71 million were deposited by Hardy under local requirements of regulatory authorities as of September 30, 2012.

13

Note C. Earnings Per Share

Earnings per share attributable to the Company's common stockholders 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) attributable to CNA 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, 2012, approximately 450 thousandand 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 thousandand740 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, 2011, approximately 279 thousand and 286 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 1.2 million and 1.1 million 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.

A security is impaired if the fair value of the security is less than its cost adjusted for accretion, amortization and previously recorded OTTI losses, otherwise defined as an unrealized loss. When a security is impaired, the impairment is evaluated to determine whether it is temporary or other-than-temporary.

Significant judgment is required in the determination of whether an OTTI loss has occurred for a security. The Company follows a consistent and systematic process for determining and recording an OTTI loss. The Company has established a committee responsible for the OTTI process. This committee, referred to as the Impairment Committee, is made up of three officers appointed by the Company’s Chief Financial Officer (CFO). The Impairment Committee is responsible for evaluating all securities in an unrealized loss position on at least a quarterly basis.

The Impairment Committee’s assessment of whether an OTTI loss has occurred incorporates both quantitative and qualitative information. Fixed maturity securities that the Company intends to sell, or it more likely than not will be required to sell before recovery of amortized cost, are considered to be other-than-temporarily impaired and the entire difference between the amortized cost basis and fair value of the security is recognized as an OTTI loss in earnings. The remaining fixed maturity securities in an unrealized loss position are evaluated to determine if a credit loss exists. The factors considered by the Impairment Committee include (a) the financial condition and near term prospects of the issuer, (b) whether the debtor is current on interest and principal payments, (c) credit ratings of the securities and (d) general market conditions and industry or sector specific outlook. The Company also considers results and analysis of cash flow modeling for asset-backed securities, and when appropriate, other fixed maturity securities. The focus of the analysis for asset-backed securities is on assessing the sufficiency and quality of underlying collateral and timing of cash flows based on scenario tests. If the present value of the modeled expected cash flows equals or exceeds the amortized cost of a security, no credit loss is judged to exist and the asset-backed security is deemed to be temporarily impaired. If the present value of the expected cash flows is less than amortized cost, the security is judged to be other-than-temporarily impaired for credit reasons and that shortfall, referred to as the credit component, is recognized as an OTTI loss in earnings. The difference between the adjusted amortized cost basis and fair value, referred to as the non-credit component, is recognized as OTTI in Other comprehensive income. In subsequent reporting periods, a change in intent to sell or further credit impairment on a security whose fair value has not deteriorated will cause the non-credit component originally recorded as OTTI in Other comprehensive income to be recognized as an OTTI loss in earnings.

16

The Company performs the discounted cash flow analysis using stressed scenarios to determine future expectations regarding recoverability. For asset-backed securities, significant assumptions enter into these cash flow projections including delinquency rates, probable risk of default, loss severity upon a default, over collateralization and interest coverage triggers, and credit support from lower level tranches.

The Company applies the same impairment model as described above for the majority of non-redeemable preferred stock securities on the basis that these securities possess characteristics similar to debt securities and that the issuers maintain their ability to pay dividends. For all other equity securities, in determining whether the security is other-than-temporarily impaired, the Impairment Committee considers a number of factors including, but not limited to: (a) the length of time and the extent to which the fair value has been less than amortized cost, (b) the financial condition and near term prospects of the issuer, (c) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for an anticipated recovery in value and (d) general market conditions and industry or sector specific outlook.

The following tables provide a summary of fixed maturity and equity securities.

The net unrealized gains on investments included in the tables above are recorded as a component of AOCI. When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. At September 30, 2012 and December 31, 2011, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $1,277 million and $723 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 is recorded, net of tax, as a reduction through Other comprehensive income (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.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2012 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 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, 2012.

The amount of pretax net realized gains (losses) on available-for-sale securities reclassified out of AOCI into earnings was $12 million and $59 million for the three and nine months ended September 30, 2012 and $(29) million and $12 million for the three and nine months ended September 30, 2011.

The following table summarizes the activity for the three and nine months ended September 30, 2012 and 2011 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at September 30, 2012 and 2011 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

Note F. 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 CFO. 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.

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 $106 million of transfers from Level 2 to Level 1 during the three and nine months ended September 30, 2012 and no transfers between Level 1 and Level 2 during the three or nine months ended September 30, 2011. 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 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. Fair value of 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.

Derivative and Other Financial Instruments

Exchange traded derivatives, primarily futures, are valued using quoted market prices and are classified within Level 1 of the fair value hierarchy. Level 2 derivatives primarily include currency forwards valued using observable

29

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. Other financial instruments consist of Level 3 securities for which the fair value option has been elected which contain embedded derivatives and are priced using either broker/dealer quotes or internal models with inputs that are not market observable.

Short Term Investments

The valuation of 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.

	Fair Value at September 30, 2012		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Assets
(In millions)
Fixed maturity securities	$	98	Discounted cash flow	Expected call date	3.6 - 5.6 years (4.6 years)
	$	61	Market approach	Private offering price	$60.00 - $105.00 ($101.49)
Equity securities	$	33	Market approach	Private offering price	$0.10 - $3,842.00 per share ($583.95 per share)
	$	17	Income approach	EBITDA projection (1)	$80 million
				EBITDA multiple (1)	1.82
Life settlement contracts	$	113	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	65% - 928% (185%)

_{(1) Earnings before interest, tax, depreciation and amortization} 

For fixed maturity securities, an increase to the expected call date assumption or decrease in the private offering price would result in a lower fair value measurement. For equity securities, an increase in the private offering price, earnings projections and earnings multiples 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.

September 30, 2012	Carrying Amount		Estimated Fair Value
(In millions)			Level 1		Level 2		Level 3		Total
Financial assets
Notes receivable for the issuance of common stock	$	21	$	—	$	—	$	21	$	21
Mortgage loans	358		—		—		374		374
Financial liabilities
Premium deposits and annuity contracts	$	103	$	—	$	—	$	108	$	108
Short term debt	13		—		13		—		13
Long term debt	2,557		—		2,986		—		2,986

December 31, 2011	Carrying Amount		Estimated Fair Value

Financial assets
Notes receivable for the issuance of common stock	$	22	$	22
Mortgage loans	234		247
Financial liabilities
Premium deposits and annuity contracts	$	109	$	114
Short term debt	83		84
Long term debt	2,525		2,679

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.

31

Note G. 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 $27 million and $123 million for the three and nine months ended September 30, 2012. Catastrophe losses in 2012 related primarily to U.S. storms and Hurricane Isaac. The Company reported catastrophe losses, net of reinsurance, of $50 million and $205 million for the three and nine months ended September 30, 2011.

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, 2012 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $118 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.

The Company has entered into a limited number of contracts with minimum payments, primarily related to outsourced services and software. Estimated future minimum payments under these contracts, which amounted to approximately $13 million at September 30, 2012, were $6 million in 2012, $2 million in 2013 and $5 million thereafter.

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, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $758 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, 2012, 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, 2012 and December 31, 2011, the Company had recorded liabilities of approximately $14 million and $15 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.

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 acquired Hardy on July 2, 2012. Further information on Hardy is set forth in Note B. 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, 2011, other than the accounting for deferred acquisition costs, as further discussed in Note A herein. The Company manages most of its assets on a legal entity basis, while segment operations are conducted across legal entities. As such, only insurance and reinsurance receivables, insurance reserves and deferred acquisition costs are readily identifiable by individual segment. Distinct investment portfolios are not maintained for each individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, 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) attributable to CNA 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 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 significant components of the Company's continuing operations and selected balance sheet items 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 2011 statutory net written premiums, we are the seventh largest commercial insurance writer and the 13^th largest property and casualty insurance organization in the United States of America. References to net operating income (loss), net realized investment gains (losses) and net income (loss) used in this MD&A reflect amounts attributable to CNA, unless otherwise noted.

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 SEC for the year ended December 31, 2011.

We utilize the net operating income financial measure to monitor our operations. Net operating income is calculated by excluding from net income (loss) attributable to CNA 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 K to the Condensed Consolidated Financial Statements included under Part I, Item 1. In evaluating 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 G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Acquisition of Hardy

On July 2, 2012, we acquired Hardy Underwriting Bermuda Limited and its subsidiaries (Hardy), a specialized Lloyd's underwriter. Hardy has business operations in the United Kingdom, Bermuda, Bahrain, Guernsey and Singapore. The acquisition of Hardy aligns with our specialized underwriting focus and will be a key platform for expanding our global business through the Lloyd's marketplace. The Lloyd's market provides access to international licenses, sophisticated excess and surplus insurance business and other syndicated risks. Hardy continues to operate under its own brand and its existing leadership team.

Further information on the acquisition of Hardy is set forth in Note B to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

We have adjusted our previously reported financial information included herein, to reflect the change in accounting guidance for costs associated with acquiring or renewing insurance contracts. This MD&A gives effect to the adjustment of the Condensed Consolidated Financial Statements. See Note A to the Condensed Consolidated Financial Statements included under Part I, Item 1 for additional information.

Three Month Comparison

Net income increased $146 million for the three months ended September 30, 2012 as compared with the same period in 2011, primarily driven by improved net operating income.

Net realized investment results improved $21 million for the three months ended September 30, 2012 as compared with the same period in 2011. See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.

Net operating income increased $125 million for the three months ended September 30, 2012 as compared with the same period in 2011. Net operating income increased $134 million for our core segments, CNA Specialty, CNA Commercial and Hardy. This increase was primarily due to higher net investment income, driven by significantly favorable limited partnership results, and lower catastrophe losses, partially offset by decreased favorable net prior year development. Catastrophe losses were $18 million after-tax for the three months ended September 30, 2012 as compared to $32 million after-tax for the same period in 2011. Net operating results decreased $9 million for our non-core segments, primarily due to unfavorable morbidity in our long term care business.

46

Favorable net prior year development of $47 million and $72 million was recorded for the three months ended September 30, 2012 and 2011 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, 2012 and 2011 is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net earned premiums increased $49 million for the three months ended September 30, 2012 as compared with the same period in 2011, primarily driven by the acquisition of Hardy. See the Segment Results section of this MD&A for further discussion.

Nine Month Comparison

Net income increased $218 million for the nine months ended September 30, 2012 as compared with the same period in 2011. This increase was due to improved net operating income and increased net realized investment gains.

Net realized investment gains increased $41 million for the nine months ended September 30, 2012 as compared with the same period in 2011. See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.

Net operating income increased $176 million for the nine months ended September 30, 2012 as compared with the same period in 2011. Net operating income increased $159 million for our core segments, CNA Specialty, CNA Commercial and Hardy. This increase was primarily due to higher net investment income, driven by favorable limited partnership income, and lower catastrophe losses. Catastrophe losses were $80 million after-tax for the nine months ended September 30, 2012 as compared to $133 million after-tax for the same period in 2011. Net operating results improved $17 million for our non-core segments, driven by results in our Life and Group Non-Core segment.

Favorable net prior year development of $165 million and $179 million was recorded for the nine months ended September 30, 2012 and 2011 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, 2012 and 2011 is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net earned premiums increased $156 million for the nine months ended September 30, 2012 as compared with the same period in 2011, driven by increases in CNA Commercial and CNA Specialty, and the acquisition of Hardy. 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

Three Month Comparison

Net written premiums for CNA Specialty decreased $27 million for the three months ended September 30, 2012 as compared with the same period in 2011. This decrease was primarily due to lower new business levels in certain lines, partially offset by continued positive rate achievement. Net earned premiums decreased $3 million as compared with the same period in 2011. This decrease was primarily due to favorable premium development recorded in 2011, partially offset by the impact of increased net written premiums over recent quarters. Further information on premium development is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

CNA Specialty's average rate increased 5% for the three months ended September 30, 2012, as compared with flat average rate for the three months ended September 30, 2011 for the policies that renewed in each period. Retention of 86% and 87% was achieved in each respective period.

Net income increased $58 million for the three months ended September 30, 2012 as compared with the same period in 2011. This increase was driven by higher net operating income.

Net operating income increased $53 million for the three months ended September 30, 2012 as compared with the same period in 2011, primarily due to higher net investment income.

The combined ratio decreased 1.0 point for the three months ended September 30, 2012 as compared with the same period in 2011. The loss ratio decreased 3.0 points, due to the impact of increased favorable net prior year development and an improved current accident year loss ratio. The expense ratio increased 1.2 points for the three months ended September 30, 2012 as compared with the same period in 2011, primarily due to the impact of favorable premium development in 2011.

Favorable net prior year development of $40 million and $31 million was recorded for the three months ended September 30, 2012 and 2011. Further information on CNA Specialty's net prior year development for the three months ended September 30, 2012 and 2011 is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Nine Month Comparison

Net written premiums for CNA Specialty increased $34 million for the nine months ended September 30, 2012 as compared with the same period in 2011, driven by increased rate, partially offset by lower new business levels in certain lines. Net earned premiums increased $65 million as compared with the same period in 2011, consistent with increased net written premiums over recent quarters.

CNA Specialty's average rate increased 4% for the nine months ended September 30, 2012, as compared with flat average rate for the nine months ended September 30, 2011 for the policies that renewed in each period. Retention of 86% was achieved in each respective period.

Net income increased $55 million for the nine months ended September 30, 2012 as compared with the same period in 2011, primarily due to the same reason discussed above in the three month comparison.

Net operating income increased $48 million for the nine months ended September 30, 2012 as compared with the same period in 2011, primarily due to higher net investment income and the inclusion of our Surety business on a wholly-owned basis in 2012. These favorable impacts were partially offset by decreased favorable net prior year development and decreased current accident year underwriting results.

The combined ratio increased 1.1 points for the nine months ended September 30, 2012 as compared with the same period in 2011. The loss ratio remained unchanged as the impact of an improved current accident year loss ratio was offset by decreased favorable net prior year development. The expense ratio increased 0.9 points for the nine months ended September 30, 2012 as compared with the same period in 2011, primarily due to increased underwriting expenses and the impact of favorable premium development in 2011.

Favorable net prior year development of $95 million and $106 million was recorded for the nine months ended September 30, 2012 and 2011. Further information on CNA Specialty's net prior year development for the nine months ended September 30, 2012 and 2011 is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Net written premiums for the three months ended September 30, 2011 included $38 million related to FICOH, which was sold in the fourth quarter of 2011. Excluding FICOH, the increase in net written premiums was primarily driven by continued positive rate achievement. Net earned premiums decreased $8 million for the three months ended September 30, 2012 as compared with the same period in 2011. Net earned premiums for the three months ended September 30, 2011 included $35 million related to FICOH. Excluding FICOH, the increase in net earned premiums was driven by the increase in net written premiums over recent quarters.

CNA Commercial's average rate increased 8% for the three months ended September 30, 2012, as compared with an increase of 2% for the three months ended September 30, 2011 for the policies that renewed in each period. Retention of 79% was achieved in each respective period.

Net income increased $94 million for the three months ended September 30, 2012 as compared with the same period in 2011. This increase was due to increased net operating income and improved net realized investment results.

Net operating income increased $78 million for the three months ended September 30, 2012 as compared with the same period in 2011. This increase was primarily due to higher net investment income and lower catastrophe losses. These favorable impacts were partially offset by decreased favorable net prior year development. Furthermore, income tax expense of $22 million was recorded in 2011 due to an increase in the tax rate applicable to the undistributed earnings of FICOH, which was under contract for sale.

The combined ratio increased 3.1 points for the three months ended September 30, 2012 as compared with the same period in 2011. The loss ratio increased 1.8 points, primarily due to the impacts of less favorable net prior year development, partially offset by lower catastrophe losses and an improved current accident year non-catastrophe loss ratio. Catastrophe losses were $24 million, or 2.8 points of the loss ratio, for the three months ended September 30, 2012, as compared to $46 million, or 5.5 points of the loss ratio, for the three months ended September 30, 2011.

The expense ratio increased 1.4 points for the three months ended September 30, 2012 as compared with the same period in 2011, primarily due to higher underwriting expenses and the favorable impact of recoveries in 2011 on insurance receivables written off in prior years.

Excluding FICOH, the increase in net written premiums was due to the same reason discussed above in the three month comparison. Excluding FICOH, the increase in net earned premiums was driven by the increase in net written premiums over recent quarters and favorable premium development recorded in 2012. Further information on premium development is included in Note G to the Condensed Consolidated Financial Statements included under Part I, Item 1.

CNA Commercial's average rate increased 6% for the nine months ended September 30, 2012 as compared with an increase of 2% for the nine months ended September 30, 2011 for the policies that renewed in each period. Retention of 78% and 79% was achieved in each respective period.

Net income increased $121 million for the nine months ended September 30, 2012 as compared with the same period in 2011, primarily due to increased net operating income.

Net operating income increased $108 million for the nine months ended September 30, 2012 as compared with the same period in 2011. This increase was primarily due to lower catastrophe losses and higher net investment income, as well as the tax expense item in 2011 discussed above in the three month comparison. These favorable impacts were partially offset by decreased favorable net prior year development.

The combined ratio improved 2.7 points for the nine months ended September 30, 2012 as compared with the same period in 2011. The loss ratio improved 3.4 points, primarily due to the impacts of lower catastrophe losses and an improved current accident year non-catastrophe loss ratio, partially offset by decreased favorable net prior year development.

Three Month Comparison

Net loss increased $1 million for the three months ended September 30, 2012 as compared with the same period in 2011. This increase was primarily due to the $10 million impact of a release of a previously established allowance for uncollectible reinsurance receivables arising from a change in estimate in 2011. This unfavorable impact was partially offset by decreased unfavorable net prior year development and higher net investment income.

Unfavorable net prior year development of $2 million and $12 million was recorded for the three months ended September 30, 2012 and 2011.

Nine Month Comparison

Net loss decreased $12 million for the nine months ended September 30, 2012 as compared with the same period in 2011, primarily due to improved net realized investment results and lower interest expense.

Unfavorable net prior year development of $2 million and $5 million was recorded for the nine months ended September 30, 2012 and 2011.

Net investment income	$	601		$	394		$	1,719		$	1,531

Net investment income for the three months ended September 30, 2012 increased $207 million as compared with the same period in 2011. The increase was primarily driven by a significant increase in limited partnership investment results.

Net investment income for the nine months ended September 30, 2012 increased $188 million as compared with the same period in 2011. The increase was primarily driven by a significant increase in limited partnership investment income and an increase in fixed maturity securities income. The increase in fixed maturity securities income was driven by a higher invested asset base and a favorable net impact of changes in estimates of prepayments for asset-backed securities. These favorable impacts were partially offset by the effect of purchasing new investments at lower market interest rates.

The fixed maturity investment portfolio provided a pretax effective income yield of 5.4% and 5.5% for the nine months ended September 30, 2012 and 2011. Tax-exempt municipal bonds generated $70 million and $205 million of net investment income for the three and nine months ended September 30, 2012 compared with $60 million and $174 million of net investment income for the same periods in 2011.

Further information on our realized gains and losses, including our OTTI losses and impairment decision process, is set forth in Note D 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, 2012 and December 31, 2011. The classification between investment grade and non-investment grade is based on a ratings methodology that takes into account ratings from two major providers, S&P and Moody's, in that order of preference. If a security is not rated by these providers, we formulate an internal rating. At September 30, 2012 and December 31, 2011, approximately 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

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 $2,961 million and $3,200 million at September 30, 2012 and December 31, 2011.

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.

European Exposure

Our fixed maturity portfolio also includes European exposure. The following table summarizes European exposure included within fixed maturity holdings.

Total amortized cost	$	1,598	$	1,941	$	159	$	3,698

European exposure is based on application of a country of risk methodology. Country of risk is derived from the issuing entity's management location, country of primary listing, revenue and reporting currency. The acquisition of Hardy increased the fair value and amortized cost of European exposure by $89 million as of September 30, 2012. As of September 30, 2012, securities with a fair value and amortized cost of $1,951 million and $1,777 million relate to Eurozone countries, which consist of member states of the European Union that use the Euro as their national currency. Of this amount, securities with a fair value and amortized cost of $311 million and $300 million pertain to Greece, Italy, Ireland, Portugal and Spain, commonly referred to as “GIIPS.”

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Our principal 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, 2012, net cash provided by operating activities was $993 million as compared with $813 million for the same period in 2011. Cash provided by operating activities was favorably affected by increased investment income receipts in 2012 as compared with the same period in 2011. In addition, we received a $75 million federal income tax refund in 2012.

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

For the nine months ended September 30, 2012, net cash used by investing activities was $747 million as compared with $217 million for the same period in 2011. 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. Additionally, during 2012, we acquired Hardy.

Cash flows from financing activities 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, 2012, net cash used by financing activities was $195 million as compared with $588 million for the same period in 2011. During 2011, we purchased the noncontrolling interest of Surety.

Common Stock Dividends

Dividends of $0.15 per share were declared and paid in the third quarter of 2012. On October 26, 2012, we declared a quarterly dividend of $0.15 per share, payable November 29, 2012 to stockholders of record on November 13, 2012. 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.

During 2012, we entered into a new credit agreement with a syndicate of banks. The new credit agreement established a four-year $250 million senior unsecured revolving credit facility which is intended to be used for general corporate purposes. At our election, the commitments under the new credit agreement may be increased from time to time up to an additional aggregate amount of $100 million, and two one-year extensions are available prior to the first and second anniversary of the closing date subject to applicable consents. Under the new credit agreement we are required to pay a facility fee which would adjust automatically in the event of a change in our financial ratings. The new credit agreement includes several covenants, including maintenance of a minimum consolidated net worth and a specified ratio of consolidated indebtedness to consolidated total capitalization. In addition, our previous credit agreement was canceled as of the effective date of the new credit agreement. As of September 30, 2012, we had no outstanding borrowings under the new credit agreement.

During 2012, CCC repaid to CNAF the $250 million outstanding balance of the $1.0 billion surplus note which was originally issued in 2008. Additionally, CCC paid a dividend of $300 million. As of September 30, 2012, CCC is able to pay approximately $690 million of dividends during the remainder of 2012 that would not be subject to the prior approval of the Illinois Department of Insurance.

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 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.

63

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, 2012. 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, 2011 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

Evaluation of Disclosure 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, 2012, 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, 2012.

Changes in Internal Control over Financial Reporting

On July 2, 2012, we completed the acquisition of Hardy. Hardy's existing disclosure controls and procedures supported their financial reporting as a separate publicly-traded company. In conducting our evaluation of the effectiveness of our internal control over financial reporting, we have elected to exclude Hardy from our evaluation as permitted under SEC rules. We are currently in the process of evaluating and integrating Hardy's controls over financial reporting with ours. We expect to complete this integration by June 30, 2013.

Other than as noted above, 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, 2012 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]

General

Note A. General

Basis of Presentation

The Condensed Consolidated Financial Statements (Unaudited) include the accounts of CNA Financial Corporation (CNAF) and its controlled subsidiaries. Collectively, CNAF and its controlled subsidiaries are referred to as CNA or the Company. CNA’s property and casualty and remaining life and group insurance operations are primarily conducted by Continental Casualty Company (CCC), The Continental Insurance Company, Western Surety Company, and Continental Assurance Corporation. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of September 30, 2012.

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 (SEC) for the year ended December 31, 2011, 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, 2012 and for the three and nine months ended September 30, 2012 and 2011 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.

Noncontrolling Interests

Net income attributable to noncontrolling interests for the three and nine months ended September 30, 2011 represented the noncontrolling interests in CNA Surety Corporation (Surety) and First Insurance Company of Hawaii (FICOH). On June 10, 2011, CNA completed the acquisition of the noncontrolling interest of Surety and on November 29, 2011, CNA completed the sale of its 50% ownership interest in FICOH.

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

In October 2010, the Financial Accounting Standards Board issued updated accounting guidance which limits the capitalization of costs incurred to acquire or renew insurance contracts to those that are incremental direct costs of successful contract acquisitions. The previous guidance allowed the capitalization of acquisition costs that vary with and are primarily related to the acquisition of new and renewal insurance contracts, whether the costs related to successful or unsuccessful efforts.

As of January 1, 2012, the Company adopted the updated accounting guidance prospectively as of January 1, 2004, the earliest date practicable. Due to the lack of available historical data related to certain accident and health contracts issued prior to January 1, 2004, a full retrospective application of the change in accounting guidance was impracticable. Acquisition costs capitalized prior to January 1, 2004 will continue to be accounted for under the previous accounting guidance and will be amortized over the premium-paying period of the related policies using assumptions consistent with those used for computing future policy benefit reserves for such contracts.

For the three and nine months ended September 30, 2012, the adoption of the new accounting guidance resulted in no impact and a $3 million decrease in Net income attributable to CNA and no impact and a $0.01 decrease in Basic and Diluted earnings per share attributable to CNA common stockholders.

The Company has adjusted its previously reported financial information included herein to reflect the change in accounting guidance for deferred acquisition costs. The impacts of adopting the new accounting standard on the Company's Condensed Consolidated Balance Sheet as of December 31, 2011 were a $106 million decrease in Deferred acquisition costs and a $37 million increase in Deferred income taxes. The impacts to Accumulated other comprehensive income (AOCI) and Additional paid-in capital were the result of the indirect effects of the Company's adoption of this guidance on Shadow Adjustments, as further discussed in Note D, and the Company's acquisition of the noncontrolling interest of Surety as discussed above.

The impacts on the Company's Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2011 were a $59 million and $171 million decrease in Amortization of deferred acquisition costs, a $59 million and $178 million increase in Other operating expenses, a $1 million and $2 million decrease in Income tax expense, and a $1 million increase and no impact in Net income attributable to noncontrolling interests, resulting in no impact and a $5 million decrease in Net income attributable to CNA, and no impact and a $0.02 decrease in Basic and Diluted earnings per share attributable to CNA common stockholders. There were no changes to net cash flows from operating, investing or financing activities for the comparative periods presented as a result of the adoption of the new accounting standard.

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, 2012 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $118 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.

The Company has entered into a limited number of contracts with minimum payments, primarily related to outsourced services and software. Estimated future minimum payments under these contracts, which amounted to approximately $13 million at September 30, 2012, were $6 million in 2012, $2 million in 2013 and $5 million thereafter.

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, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $758 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, 2012, 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, 2012 and December 31, 2011, the Company had recorded liabilities of approximately $14 million and $15 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.

(b) Includes net unrealized gains (losses) related to changes in the fair value of securities for which the fair value option has been elected. There were no net unrealized gains (losses) included in the three months ended September 30, 2012 or 2011 or the nine months ended September 30, 2012. There were $1 million of net unrealized gains for the nine months ended September 30, 2011.

The components of net other-than-temporary impairment (OTTI) losses recognized in earnings by asset type are summarized in the following table.

A security is impaired if the fair value of the security is less than its cost adjusted for accretion, amortization and previously recorded OTTI losses, otherwise defined as an unrealized loss. When a security is impaired, the impairment is evaluated to determine whether it is temporary or other-than-temporary.

Significant judgment is required in the determination of whether an OTTI loss has occurred for a security. The Company follows a consistent and systematic process for determining and recording an OTTI loss. The Company has established a committee responsible for the OTTI process. This committee, referred to as the Impairment Committee, is made up of three officers appointed by the Company’s Chief Financial Officer (CFO). The Impairment Committee is responsible for evaluating all securities in an unrealized loss position on at least a quarterly basis.

The Impairment Committee’s assessment of whether an OTTI loss has occurred incorporates both quantitative and qualitative information. Fixed maturity securities that the Company intends to sell, or it more likely than not will be required to sell before recovery of amortized cost, are considered to be other-than-temporarily impaired and the entire difference between the amortized cost basis and fair value of the security is recognized as an OTTI loss in earnings. The remaining fixed maturity securities in an unrealized loss position are evaluated to determine if a credit loss exists. The factors considered by the Impairment Committee include (a) the financial condition and near term prospects of the issuer, (b) whether the debtor is current on interest and principal payments, (c) credit ratings of the securities and (d) general market conditions and industry or sector specific outlook. The Company also considers results and analysis of cash flow modeling for asset-backed securities, and when appropriate, other fixed maturity securities. The focus of the analysis for asset-backed securities is on assessing the sufficiency and quality of underlying collateral and timing of cash flows based on scenario tests. If the present value of the modeled expected cash flows equals or exceeds the amortized cost of a security, no credit loss is judged to exist and the asset-backed security is deemed to be temporarily impaired. If the present value of the expected cash flows is less than amortized cost, the security is judged to be other-than-temporarily impaired for credit reasons and that shortfall, referred to as the credit component, is recognized as an OTTI loss in earnings. The difference between the adjusted amortized cost basis and fair value, referred to as the non-credit component, is recognized as OTTI in Other comprehensive income. In subsequent reporting periods, a change in intent to sell or further credit impairment on a security whose fair value has not deteriorated will cause the non-credit component originally recorded as OTTI in Other comprehensive income to be recognized as an OTTI loss in earnings.

The Company performs the discounted cash flow analysis using stressed scenarios to determine future expectations regarding recoverability. For asset-backed securities, significant assumptions enter into these cash flow projections including delinquency rates, probable risk of default, loss severity upon a default, over collateralization and interest coverage triggers, and credit support from lower level tranches.

The Company applies the same impairment model as described above for the majority of non-redeemable preferred stock securities on the basis that these securities possess characteristics similar to debt securities and that the issuers maintain their ability to pay dividends. For all other equity securities, in determining whether the security is other-than-temporarily impaired, the Impairment Committee considers a number of factors including, but not limited to: (a) the length of time and the extent to which the fair value has been less than amortized cost, (b) the financial condition and near term prospects of the issuer, (c) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for an anticipated recovery in value and (d) general market conditions and industry or sector specific outlook.

The following tables provide a summary of fixed maturity and equity securities.

The net unrealized gains on investments included in the tables above are recorded as a component of AOCI. When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. At September 30, 2012 and December 31, 2011, the net unrealized gains on investments included in AOCI were net of after-tax Shadow Adjustments of $1,277 million and $723 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 is recorded, net of tax, as a reduction through Other comprehensive income (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.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2012 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 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, 2012.

The amount of pretax net realized gains (losses) on available-for-sale securities reclassified out of AOCI into earnings was $12 million and $59 million for the three and nine months ended September 30, 2012 and $(29) million and $12 million for the three and nine months ended September 30, 2011.

The following table summarizes the activity for the three and nine months ended September 30, 2012 and 2011 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at September 30, 2012 and 2011 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

Earnings (Loss) Per Share [Abstract]

Earnings Per Share [Text Block]

Note C. Earnings Per Share

Earnings per share attributable to the Company's common stockholders 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) attributable to CNA 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, 2012, approximately 450 thousandand 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 thousandand740 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, 2011, approximately 279 thousand and 286 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 1.2 million and 1.1 million 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.

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 acquired Hardy on July 2, 2012. Further information on Hardy is set forth in Note B. 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, 2011, other than the accounting for deferred acquisition costs, as further discussed in Note A herein. The Company manages most of its assets on a legal entity basis, while segment operations are conducted across legal entities. As such, only insurance and reinsurance receivables, insurance reserves and deferred acquisition costs are readily identifiable by individual segment. Distinct investment portfolios are not maintained for each individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, 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) attributable to CNA 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 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 significant components of the Company's continuing operations and selected balance sheet items are presented in the following tables.

Claim and Claim Adjustment Expense Reserves

9 Months Ended

Insurance Loss Reserves [Abstract]

Claim and Claim Adjustment Expense Reserves

Note G. 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 $27 million and $123 million for the three and nine months ended September 30, 2012. Catastrophe losses in 2012 related primarily to U.S. storms and Hurricane Isaac. The Company reported catastrophe losses, net of reinsurance, of $50 million and $205 million for the three and nine months ended September 30, 2011.

For the nine months ended September 30, 2012, favorable premium development was recorded for CNA Commercial primarily due to premium adjustments on auditable policies arising from increased exposures.

For the three and nine months ended September 30, 2011, favorable premium development was recorded for CNA Specialty primarily due to changes in estimates of exposures in medical professional liability tail coverages.

For the nine months ended September 30, 2011, unfavorable premium development for CNA Commercial was recorded due to a further reduction of ultimate premium estimates relating to retrospectively rated policies, partially offset by premium adjustments on auditable policies due to increased exposures.

Fair Value Disclosures [Abstract]

Fair Value

Note F. 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 CFO. 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.

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 $106 million of transfers from Level 2 to Level 1 during the three and nine months ended September 30, 2012 and no transfers between Level 1 and Level 2 during the three or nine months ended September 30, 2011. 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 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. Fair value of 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.

Derivative and Other Financial Instruments

Exchange traded derivatives, primarily futures, are valued using quoted market prices and are classified within Level 1 of the fair value hierarchy. Level 2 derivatives primarily include 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. Other financial instruments consist of Level 3 securities for which the fair value option has been elected which contain embedded derivatives and are priced using either broker/dealer quotes or internal models with inputs that are not market observable.

Short Term Investments

The valuation of 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.

	Fair Value at September 30, 2012		Valuation Technique(s)	Unobservable Input(s)	Range  (Weighted Average)
Assets
(In millions)
Fixed maturity securities	$	98	Discounted cash flow	Expected call date	3.6 - 5.6 years (4.6 years)
	$	61	Market approach	Private offering price	$60.00 - $105.00 ($101.49)
Equity securities	$	33	Market approach	Private offering price	$0.10 - $3,842.00 per share ($583.95 per share)
	$	17	Income approach	EBITDA projection (1)	$80 million
				EBITDA multiple (1)	1.82
Life settlement contracts	$	113	Discounted cash flow	Discount rate risk premium	9%
				Mortality assumption	65% - 928% (185%)

_{(1) Earnings before interest, tax, depreciation and amortization} 

For fixed maturity securities, an increase to the expected call date assumption or decrease in the private offering price would result in a lower fair value measurement. For equity securities, an increase in the private offering price, earnings projections and earnings multiples 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.

Financial liabilities
Premium deposits and annuity contracts	$	109	$	114
Short term debt	83		84
Long term debt	2,525		2,679

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.

Hardy [Abstract]

Business Combination Disclosure [Text Block]

Note B. Hardy

On July 2, 2012, the Company completed the previously announced acquisition of all outstanding shares of Hardy Underwriting Bermuda Limited and its subsidiaries (Hardy), a specialized Lloyd's of London (Lloyd's) underwriter. Through Lloyd's Syndicate 382, Hardy underwrites primarily short-tail exposures in marine and aviation, non-marine property, specialty lines and property treaty reinsurance. The acquisition of Hardy aligns with the Company's specialized underwriting focus and will be a key platform for expanding the Company's global business through the Lloyd's marketplace. The results of Hardy for the period from July 2, 2012 to September 30, 2012 are included in the results of our core property and casualty insurance operations as a separate segment.

For the year ended December 31, 2011, Hardy reported gross written premiums of $430 million and recorded a loss of $55 million in its group consolidated financial statements prepared in accordance with International Financial Reporting Standards.

The purchase price for Hardy was $231 million. Acquisition related expenses of $4 million were incurred during the nine months ended September 30, 2012, including investment advisory, legal and other expenses, and were recorded in the Corporate and Other Non-Core segment.

The fair value of the assets acquired and the liabilities assumed as a result of the acquisition of Hardy were as follows:

(In millions)	Acquisition Date

Short term investments	255

Total assets acquired	$	1,166
Claim and claim adjustment expenses	$	500

The intangible assets acquired are presented in the following table.

Total indefinite-lived intangible assets	55

Trade name	8		8 years
Distribution channel	13		15 years
Total finite-lived intangible assets	81
Total intangible assets as of the acquisition date	$	136

For the three months ended September 30, 2012, amortization expense of $18 million was included in Amortization of deferred acquisition costs and $6 million was included in Other operating expenses in the Statement of Operations for the Hardy segment. Estimated future amortization expense for these intangible assets is $19 million in the fourth quarter of 2012, $21 million in 2013, $4 million in 2014, $1 million in 2015 and $2 million in both 2016 and 2017.

The acquisition resulted in goodwill of $35 million which was recorded in the Hardy segment. The recognized goodwill is based on the Company's expected growth and profitability of Hardy. The goodwill is not deductible for tax purposes.

Lloyd's requires syndicate capital providers to provide funds at Lloyd's (FAL) which is available to Lloyd's should funds in the Lloyd's premium trust fund be insufficient to cover obligations. At September 30, 2012, the Company had a deposit of $66 million of short duration U.S. Treasury securities in a Lloyd's custody account related to the FAL. Although the Company still owns these securities, these securities are controlled by Lloyd's and are therefore restricted. Additionally, cash and securities with a carrying value of approximately $71 million were deposited by Hardy under local requirements of regulatory authorities as of September 30, 2012.
