PART I

ITEM 1. BUSINESS

CNA Financial Corporation (CNAF) was incorporated in 1967 and is an insurance holding company. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. References to “CNA,” “the Company,” “we,” “our,” “us” or like terms refer to the business of CNAF and its subsidiaries. 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, Hardy Underwriting Bermuda Limited and its subsidiaries and Continental Assurance Company (CAC). Loews Corporation (Loews) owned approximately 90% of our outstanding common stock as of December 31, 2012.

Our insurance products primarily include commercial property and casualty coverages, including surety. Our services include risk management, information services, warranty and claims administration. Our products and services are primarily marketed through independent agents, brokers and managing general underwriters to a wide variety of customers, including small, medium and large businesses, insurance companies, associations, professionals and other groups.

Our core business, commercial property and casualty insurance operations, is reported in three business segments: CNA Specialty, CNA Commercial and Hardy. Our non-core businesses are managed in two business segments: Life & Group Non-Core and Corporate & Other Non-Core. Each segment is managed separately due to differences in their product lines and markets. Discussions of each segment, including the products offered, customers served, and distribution channels used, are set forth in the Management's Discussion and Analysis (MD&A) included under Item 7 and in Note O to the Consolidated Financial Statements included under Item 8.

Competition

The property and casualty insurance industry is highly competitive both as to rate and service. We compete with a large number of stock and mutual insurance companies and other entities for both distributors and customers. Insurers compete on the basis of factors including products, price, services, ratings and financial strength. We must continuously allocate resources to refine and improve our insurance products and services.

There are approximately 2,800 individual companies that sell property and casualty insurance in the United States. 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.

Regulation

The insurance industry is subject to comprehensive and detailed regulation and supervision. Each domestic and foreign jurisdiction has established supervisory agencies with broad administrative powers relative to licensing insurers and agents, approving policy forms, establishing reserve requirements, prescribing the form and content of statutory financial reports, and regulating capital adequacy and the type, quality and amount of investments permitted. Such regulatory powers also extend to premium rate regulations, which require that rates not be excessive, inadequate or unfairly discriminatory. In addition to regulation of dividends by insurance subsidiaries, intercompany transfers of assets may be subject to prior notice or approval by insurance regulators, depending on the size of such transfers and payments in relation to the financial position of the insurance subsidiaries making the transfer or payment.

Hardy, a specialized Lloyd's of London (Lloyd's) underwriter, is also supervised by the Council of Lloyd's, which is the franchisor for all Lloyd's operations. The Council of Lloyd's has wide discretionary powers to regulate Lloyd's underwriting, such as establishing the capital requirements for syndicate participation. In addition, the annual business plans of each syndicate are subject to the review and approval of the Lloyd's Franchise Board, which is responsible for business planning and monitoring for all syndicates.

The European Union's executive body, the European Commission, is implementing new capital adequacy and risk management regulations called Solvency II that would apply to our European operations. In addition, global regulators, including the United States National Association of Insurance Commissioners, are working with the International Association of Insurance Supervisors (IAIS) to consider changes to insurance company supervision. Among the areas being addressed are company and group capital requirements, group supervision and enterprise

risk management. It is not currently clear to what extent or how the activities of the IAIS will impact the Company or U.S. insurance regulation.

Domestic insurers are also required by the state insurance regulators to provide coverage to insureds who would not otherwise be considered eligible by the insurers. Each state dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each state.

Further, insurance companies are subject to state guaranty fund and other insurance-related assessments. Guaranty fund assessments are levied by the state departments of insurance to cover claims of insolvent insurers. Other insurance-related assessments are generally levied by state agencies to fund various organizations including disaster relief funds, rating bureaus, insurance departments, and workers' compensation second injury funds, or by industry organizations that assist in the statistical analysis and ratemaking process.

Although the federal government does not directly regulate the business of insurance, federal legislative and regulatory initiatives can impact the insurance industry in a variety of ways. These initiatives and legislation include tort reform proposals; proposals addressing natural catastrophe exposures; terrorism risk mechanisms; federal financial services reforms; various tax proposals affecting insurance companies; and possible regulatory limitations, impositions and restrictions arising from the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as the Patient Protection and Affordable Care Act, both enacted in 2010.

Various legislative and regulatory efforts to reform the tort liability system have, and will continue to, impact our industry. Although there has been some tort reform with positive impact to the insurance industry, new causes of action and theories of damages continue to be proposed in state court actions or by federal or state legislatures that continue to expand liability for insurers and their policyholders. For example, some state legislatures have from time to time considered legislation addressing direct actions against insurers related to bad faith claims. As a result of this unpredictability in the law, insurance underwriting is expected to continue to be difficult in commercial lines, professional liability and other specialty coverages.

The Dodd-Frank Wall Street Reform and Consumer Protection Act expanded the federal presence in insurance oversight and may increase the regulatory requirements to which we may be subject. The Act's requirements include streamlining the state-based regulation of reinsurance and nonadmitted insurance (property or casualty insurance placed from insurers that are eligible to accept insurance, but are not licensed to write insurance in a particular state). The Act also established a new Federal Insurance Office within the U.S. Department of the Treasury. The Act called for numerous studies and contemplates further regulation.

The Patient Protection and Affordable Care Act and the related amendments in the Health Care and Education Reconciliation Act may increase our operating costs and underwriting losses. This landmark legislation may lead to numerous changes in the health care industry that could create additional operating costs for us, particularly with respect to our workers' compensation and long term care products.

Employee Relations

As of December 31, 2012, we had approximately 7,500 employees and have experienced satisfactory labor relations. We have never had work stoppages due to labor disputes.

We have comprehensive benefit plans for substantially all of our employees, including retirement plans, savings plans, disability programs, group life programs and group health care programs. See Note K to the Consolidated Financial Statements included under Item 8 for further discussion of our benefit plans.

Property and Casualty Claim and Claim Adjustment Expenses

The following loss reserve development table illustrates the change over time of reserves established for property and casualty claim and claim adjustment expenses at the end of the preceding ten calendar years for our property and casualty insurance companies. The table excludes our life insurance subsidiaries, and as such, the carried reserves will not agree to the Consolidated Financial Statements included under Item 8. The first section shows the reserves as originally reported at the end of the stated year. The second section, reading down, shows the cumulative amounts paid as of the end of successive years with respect to the originally reported reserve liability. The third section, reading down, shows re-estimates of the originally recorded reserves as of the end of each successive year, which is the result of our property and casualty insurance subsidiaries' expanded awareness of additional facts and circumstances that pertain to the unsettled claims. The last section compares the latest re-estimated reserves to the reserves originally established, and indicates whether the original reserves were adequate or inadequate to cover the estimated costs of unsettled claims.

The loss reserve development table is cumulative and, therefore, ending balances should not be added since the amount at the end of each calendar year includes activity for both the current and prior years. The development amounts in the table below include the impact of reinsurance commutations, but exclude the impact of the provision for uncollectible reinsurance.

ITEM 1A. RISK FACTORS

Our business faces many risks. Each of the risks and uncertainties described below could lead to events or circumstances that have a material adverse effect on our results of operations, equity, business and insurer financial strength and corporate debt ratings. You should carefully consider and evaluate all of the information included in this Report and any subsequent reports we may file with the SEC or make available to the public before investing in any securities we issue.

If we determine that our recorded insurance reserves are insufficient to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, we may need to increase our insurance reserves.

We maintain insurance reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for reported and unreported claims and for future policy benefits. Reserves represent our best estimate at a given point in time. Insurance reserves are not an exact calculation of liability but instead are complex estimates derived by us, generally utilizing a variety of reserve estimation techniques from numerous assumptions and expectations about future events, many of which are highly uncertain, such as estimates of claims severity, frequency of claims, mortality, morbidity, discount rates, inflation, claims handling, case reserving policies and procedures, underwriting and pricing policies, changes in the legal and regulatory environment and the lag time between the occurrence of an insured event and the time of its ultimate settlement. Mortality is the relative incidence of death. Morbidity is the frequency and severity of illness, sickness and diseases contracted. Many of these uncertainties are not precisely quantifiable and require significant judgment on our part. As trends in underlying claims develop, particularly in so-called “long tail” or long duration coverages, we are sometimes required to add to our reserves. This is called unfavorable net prior year development and results in a charge to our earnings in the amount of the added reserves, recorded in the period the change in estimate is made. These charges can be substantial.

We are subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on our business by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims, resulting in further increases in our reserves. The effects of these and other unforeseen emerging claim and coverage issues are extremely hard to predict. Examples of emerging or potential claims and coverage issues include:

• the effects of worldwide economic conditions, which have resulted in an increase in the number and size of certain claims, including both directors and officers (D&O) and errors and omissions (E&O) insurance claims related to corporate failures, as well as other coverages;

• class action litigation relating to claims handling and other practices; and

• mass tort claims, including bodily injury claims related to welding rods, benzene, lead, noise induced hearing loss, injuries from various medical products including pharmaceuticals, and various other chemical and radiation exposure claims.

In light of the many uncertainties associated with establishing the estimates and making the assumptions necessary to establish reserve levels, we review and change our reserve estimates in a regular and ongoing process as experience develops and further claims are reported and settled. If estimated reserves are insufficient for any reason, the required increase in reserves would be recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges could be substantial.

8

Our key assumptions used to determine reserves for long term care products and payout annuity contracts could vary significantly from actual experience.

Our reserves for long term care products and payout annuity contracts are based on certain key assumptions including morbidity, mortality, policy persistency (the percentage of policies remaining in force) and discount rates (which are impacted by expected investment yields). A prolonged period during which interest rates remain at levels lower than those anticipated in our reserving may result in shortfalls in investment income on assets supporting policy obligations, which may require changes to reserves. These assumptions, while based on historical data and industry experience and monitored consistently, are critical bases for reserve estimates and are inherently uncertain. If estimated reserves are insufficient for any reason, the required increase in reserves would be recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges could be substantial.

Catastrophe losses are unpredictable and could result in material losses.

Catastrophe losses are an inevitable part of our business. Various events can cause catastrophe losses. These events can be natural or man-made, and may include hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, and acts of terrorism. The frequency and severity of these catastrophe events are inherently unpredictable. In addition, longer-term natural catastrophe trends may be changing and new types of catastrophe losses may be developing due to climate change, a phenomenon that has been associated with extreme weather events linked to rising temperatures, and includes effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow.

The extent of our losses from catastrophes is a function of the total amount of our insured exposures in the affected areas, the frequency and severity of the events themselves, the level of reinsurance assumed and ceded, and reinsurance reinstatement premiums, if any. As in the case of catastrophe losses generally, it can take a long time for the ultimate cost to us to be finally determined, as a multitude of factors contribute to such costs, including evaluation of general liability and pollution exposures, additional living expenses, infrastructure disruption, business interruption and reinsurance collectibility. Reinsurance coverage for terrorism events is provided only in limited circumstances, especially in regard to “unconventional” terrorism acts, such as nuclear, biological, chemical or radiological attacks. As a result, catastrophe losses are particularly difficult to estimate.

As our claim experience develops on a specific catastrophe, we may be required to adjust our reserves, or take unfavorable net prior year development, to reflect our revised estimates of the total cost of claims.

We have exposures related to asbestos and environmental pollution (A&EP) claims, which could result in material losses.

Our property and casualty insurance subsidiaries have exposures related to A&EP claims. Our experience has been that establishing claim and claim adjustment expense reserves for casualty coverages relating to A&EP claims is subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment expense reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability.

On August 31, 2010, we completed a retroactive reinsurance transaction under which substantially all of our legacy A&EP liabilities were ceded to National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., subject to an aggregate limit of $4 billion (Loss Portfolio Transfer). If the other parties to the Loss Portfolio Transfer do not fully perform their obligations, our liabilities for A&EP claims covered by the Loss Portfolio Transfer exceed the aggregate limit of $4 billion, or we determine we have exposures to A&EP claims not covered by the Loss Portfolio Transfer, we may need to increase our recorded net reserves which would result in a charge against our earnings. These charges could be substantial.

Our premium writings and profitability are affected by the availability and cost of reinsurance.

We purchase reinsurance to help manage our exposure to risk. Under our ceded reinsurance arrangements, another insurer assumes a specified portion of our exposure in exchange for a specified portion of policy premiums. Market conditions determine the availability and cost of the reinsurance protection we purchase, which affects the level of our business and profitability, as well as the level and types of risk we retain. If we are unable to obtain sufficient

9

reinsurance at a cost we deem acceptable, we may be unwilling to bear the increased risk and would reduce the level of our underwriting commitments.

We may not be able to collect amounts owed to us by reinsurers, which could result in higher net incurred losses.

We have significant amounts recoverable from reinsurers which are reported as receivables on our Consolidated Balance Sheets and are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. The ceding of insurance does not, however, discharge our primary liability for claims. As a result, we are subject to credit risk relating to our ability to recover amounts due from reinsurers. In the past, certain of our reinsurance carriers have experienced credit downgrades by rating agencies within the term of our contractual relationship. Such action increases the likelihood that we will not be able to recover amounts due. In addition, reinsurers could dispute amounts which we believe are due to us. If we are not able to collect the amounts due to us from reinsurers for any of the foregoing reasons, our net incurred losses will be higher.

We may not be able to collect amounts owed to us by policyholders who hold deductible policies, which could result in higher net incurred losses.

A portion of our business is written under deductible policies. Under these policies, we are obligated to pay the related insurance claims and are reimbursed by the policyholder to the extent of the deductible, which may be significant. As a result we are exposed to credit risk to the policyholder. If we are not able to collect the amounts due to us from policyholders, our incurred losses will be higher.

We have incurred and may continue to incur significant realized and unrealized investment losses and volatility in net investment income arising from volatility in the capital and credit markets.

Our investment portfolio is exposed to various risks, such as interest rate, credit, and currency risks, many of which are unpredictable. Investment returns are an important part of our overall profitability. General economic conditions, changes in financial markets such as fluctuations in interest rates, credit conditions and currency, commodity and stock prices, and many other factors beyond our control can adversely affect the value of our investments and the realization of investment income. Further, we invest a portion of our assets in equity securities and limited partnerships which are subject to greater market volatility than our fixed income investments. In addition, limited partnership investments generally present higher illiquidity than fixed income investments. As a result of all of these factors, we may not realize an adequate return on our investments, may incur losses on sales of our investments, and may be required to write down the value of our investments.

Our valuation of investments and impairment of securities requires significant judgment, which is inherently uncertain.

We exercise significant judgment in analyzing and validating fair values, which are primarily provided by third parties, for securities in our investment portfolio, including those that are not regularly traded in active markets. We also exercise significant judgment in determining whether the impairment of particular investments is temporary or other-than-temporary. The valuation of residential and commercial mortgage and other asset-backed securities can be particularly sensitive to fairly small changes in collateral performance.

Due to the inherent uncertainties involved with these judgments, we may incur unrealized losses and conclude that other-than-temporary write downs of our investments are required.

Any significant interruption in the operation of our facilities, systems and business functions could result in a materially adverse effect on our operations.

Our business is highly dependent upon our ability to perform, in an efficient and uninterrupted manner, through our employees or vendor relationships, necessary business functions (such as Internet support and 24-hour call centers), processing new and renewal business, and processing and paying claims and other obligations. Our facilities and systems could become unavailable, inoperable, or otherwise impaired from a variety of causes, including, without limitation, natural events, such as hurricanes, tornadoes, windstorms, earthquakes, severe winter weather and fires, or other events, such as explosions, terrorist attacks, computer security breaches or cyber attacks, riots, hazardous material releases, medical epidemics, utility outages, interruptions of our data processing and storage systems or the systems of third-party vendors, or unavailability of communications facilities. Likewise,

10

we could experience a significant failure or corruption of one or more of our information technology, telecommunications, or other systems for various reasons, including significant failures that might occur as existing systems are replaced or upgraded.

The shut-down or unavailability of one or more of our systems or facilities for any reason could significantly impair our ability to perform critical business functions on a timely basis. In addition, because our information technology and telecommunications systems interface with and depend on third-party systems, we could experience service denials if demand for such service exceeds capacity or a third-party system fails or experiences an interruption. If sustained or repeated, such events could result in a deterioration of our ability to write and process new and renewal business, provide customer service, pay claims in a timely manner, or perform other necessary business functions. This could result in a materially adverse effect on our business results, prospects, and liquidity, as well as damage to customer goodwill.

Loss of key vendor relationships or failure of a vendor to protect personal information of our customers, claimants or employees could result in a materially adverse effect on our operations.

We rely on services and products provided by many vendors in the United States and abroad. These include, for example, vendors of computer hardware and software and vendors of services such as claim adjustment services and human resource benefits management services. In the event that one or more of our vendors suffers a bankruptcy or otherwise becomes unable to continue to provide products or services, or fails to protect personal information of our customers, claimants or employees, we may suffer operational impairments and financial losses.

We face intense competition in our industry and may be adversely affected by the cyclical nature of the property and casualty business.

All aspects of the insurance industry are highly competitive and we must continuously allocate resources to refine and improve our insurance products and services. We compete with a large number of stock and mutual insurance companies and other entities for both distributors and customers. Insurers compete on the basis of factors including products, price, services, ratings and financial strength. The property and casualty market is cyclical and has experienced periods characterized by relatively high levels of price competition, less restrictive underwriting standards and relatively low premium rates, followed by periods of relatively lower levels of competition, more selective underwriting standards and relatively high premium rates. During periods in which price competition is high, we may lose business to competitors offering competitive insurance products at lower prices. As a result, our premium levels and expense ratio could be materially adversely impacted.

We are subject to capital adequacy requirements and, if we are unable to maintain or raise sufficient capital to meet these requirements, regulatory agencies may restrict or prohibit us from operating our business.

Insurance companies such as us are subject to capital adequacy standards set by regulators to help identify companies that merit further regulatory attention. These standards apply specified risk factors to various asset, premium and reserve components of statutory capital and surplus reported in our statutory basis of accounting financial statements. Current rules, including those promulgated by insurance regulators and specialized markets, such as Lloyd's, require companies to maintain statutory capital and surplus at a specified minimum level determined using the applicable regulatory capital adequacy formula. If we do not meet these minimum requirements, we may be restricted or prohibited from operating our business. If we are required to record a material charge against earnings in connection with a change in estimate or the occurrence of an event, or if we incur significant losses related to our investment portfolio, we may violate these minimum capital adequacy requirements unless we are able to raise sufficient additional capital.

While Loews has provided us with substantial amounts of capital in prior years, Loews may be restricted in its ability or may not be willing to provide additional capital support to us in the future. If we are in need of additional capital, we may be required to secure this funding from sources other than Loews. We may be limited in our ability to raise significant amounts of capital on favorable terms or at all.

Our insurance subsidiaries, upon whom we depend for dividends in order to fund our working capital needs, are limited by insurance regulators in their ability to pay dividends.

We are a holding company and are dependent upon dividends, loans and other sources of cash from our subsidiaries in order to meet our obligations. Ordinary dividend payments, or dividends that do not require prior approval by

11

the insurance subsidiaries' domiciliary insurance regulator are generally limited to amounts determined by formula which varies by jurisdiction. The formula for the majority of domestic states is the greater of 10% of the prior year statutory surplus or the prior year statutory net income, less the aggregate of all dividends paid during the twelve months prior to the date of payment. Some jurisdictions, including certain domestic states, however, have an additional stipulation that dividends cannot exceed the prior year's earned surplus. If we are restricted, by regulatory rule or otherwise, from paying or receiving inter-company dividends, we may not be able to fund our working capital needs and debt service requirements from available cash. As a result, we would need to look to other sources of capital which may be more expensive or may not be available at all.

Rating agencies may downgrade their ratings of us and thereby adversely affect our ability to write insurance at competitive rates or at all.

Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries, as well as our public debt, are rated by rating agencies, namely, A.M. Best Company (A.M. Best), Moody's Investors Service, Inc. (Moody's) and Standard & Poor's (S&P). Ratings reflect the rating agency's opinions of an insurance company's or insurance holding company's financial strength, capital adequacy, operating performance, strategic position and ability to meet its obligations to policyholders and debt holders.

Due to the intense competitive environment in which we operate, the uncertainty in determining reserves and the potential for us to take material unfavorable net prior year development in the future, and possible changes in the methodology or criteria applied by the rating agencies, the rating agencies may take action to lower our ratings in the future. If our property and casualty insurance financial strength ratings are downgraded below current levels, our business and results of operations could be materially adversely affected. The severity of the impact on our business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of our insurance products to certain markets, and the required collateralization of certain future payment obligations or reserves.

In addition, it is possible that a lowering of the corporate debt ratings of Loews by certain of the rating agencies could result in an adverse impact on our ratings, independent of any change in our circumstances. We have entered into several settlement agreements and assumed reinsurance contracts that require collateralization of future payment obligations and assumed reserves if our ratings or other specific criteria fall below certain thresholds. The ratings triggers are generally more than one level below our current ratings.

We are subject to extensive federal, state, local and foreign governmental regulations that restrict our ability to do business and generate revenues.

The insurance industry is subject to comprehensive and detailed regulation and supervision. Most insurance regulations are designed to protect the interests of our policyholders rather than our investors. Each jurisdiction in which we do business has established supervisory agencies that regulate the manner in which we do business. In addition, the Lloyd's marketplace sets rules under which its members, including our Hardy syndicate, operate.

These rules and regulations relate to, among other things, the following:

• standards of solvency including risk-based capital measurements;

• restrictions on the nature, quality and concentration of investments;

• restrictions on our ability to withdraw from unprofitable lines of insurance or unprofitable market areas;

• the required use of certain methods of accounting and reporting;

• the establishment of reserves for unearned premiums, losses and other purposes;

• potential assessments for funds necessary to settle covered claims against impaired, insolvent or failed private or quasi-governmental insurers;

• licensing of insurers and agents;

• approval of policy forms;

• limitations on the ability of our insurance subsidiaries to pay dividends to us; and

12

• limitations on the ability to non-renew, cancel or change terms and conditions in policies.

Regulatory powers also extend to premium rate regulations which require that rates not be excessive, inadequate or unfairly discriminatory. The jurisdictions in which we do business may also require us to provide coverage to persons whom we would not otherwise consider eligible. Each jurisdiction dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each jurisdiction.

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.

Acquisition of Hardy

On July 2, 2012, we acquired Hardy Underwriting Bermuda Limited and its subsidiaries, 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 Consolidated Financial Statements included under Item 8.

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 Consolidated Financial Statements. See Note A to the Consolidated Financial Statements included under Item 8 for additional information.

2012 Compared with 2011

Net income increased $16 million in 2012 as compared with 2011, driven by increased net realized investment gains, partially offset by lower net operating income.

Net realized investment gains increased $38 million in 2012 as compared with 2011. See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.

Net operating income decreased $23 million in 2012 as compared with 2011. Net operating income decreased $126 million for our core segments, CNA Specialty, CNA Commercial and Hardy. This decrease was primarily due to higher catastrophe impacts and decreased favorable net prior year development. These unfavorable impacts were partially offset by higher net investment income, driven by significantly favorable limited partnership results. Catastrophe impacts were $270 million after-tax in 2012 as compared to $144 million after-tax in 2011. Catastrophe impacts in 2012 reflect $190 million after-tax related to Storm Sandy, including reinstatement premiums of $10 million after-tax. Net operating results improved $103 million for our non-core segments, primarily related to results in our Life & Group Non-Core segment. See the Life & Group Non-Core and Corporate & Other Non-Core sections of this MD&A for further discussion of our non-core results.

19

Favorable net prior year development of $251 million and $431 million was recorded in 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 2012 and 2011 is included in Note G to the Consolidated Financial Statements included under Item 8.

Net earned premiums increased $279 million in 2012 as compared with 2011 driven by the acquisition of Hardy, a $102 million increase in CNA Specialty and a $66 million increase in CNA Commercial. See the Segment Results section of this MD&A for further discussion.

2011 Compared with 2010

As further discussed in Note G to the Consolidated Financial Statements included under Item 8, on August 31, 2010, we completed a transaction with NICO, a subsidiary of Berkshire Hathaway Inc., under which substantially all our legacy A&EP liabilities were ceded to NICO. We recognized an after-tax loss of $365 million in the third quarter of 2010, of which $344 million related to our continuing operations and $21 million related to our discontinued operations.

Net income decreased $79 million in 2011 as compared with 2010. Excluding the loss associated with the Loss Portfolio Transfer in 2010, net income decreased $444 million in 2011 as compared with 2010 due to lower net operating income and decreased net realized investment gains.

Net realized investment gains decreased $48 million in 2011 as compared with 2010. See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.

Net operating income decreased $51 million in 2011 as compared with 2010. Excluding the loss associated with the Loss Portfolio Transfer, net operating income decreased $395 million in 2011 as compared with 2010. Net operating income decreased $253 million for our core segments, CNA Specialty and CNA Commercial. This decrease was primarily due to lower net investment income, lower favorable net prior year development, and higher catastrophe losses. Catastrophe losses were $144 million after-tax in 2011 as compared to catastrophe losses of $79 million after-tax in 2010. These unfavorable impacts were partially offset by improved non-catastrophe current accident year underwriting results, including lower expenses. Expenses in 2010 were unfavorably impacted by costs associated with our Information Technology (IT) Transformation as discussed below. Net operating results decreased $142 million for our non-core segments, Life & Group Non-Core and Corporate & Other Non-Core. This decrease was primarily due to the 2011 results in our payout annuity business, which were negatively impacted by a $115 million after-tax increase in insurance reserves, due to unlocking actuarial reserve assumptions for anticipated adverse changes in mortality and discount rates, which reflect the current low interest rate environment and our view of expected investment yields. The initial reserving assumptions for these contracts were determined at issuance, including a margin for adverse deviation, and were locked in throughout the life of the contract unless a premium deficiency developed. In 2011, a premium deficiency emerged and the actuarial reserve assumptions were unlocked and revised to management's current best estimates. See the Life & Group Non-Core and Corporate & Other Non-Core sections of this MD&A for further discussion of our non-core results.

As further discussed in Note P to the Consolidated Financial Statements included under Item 8, we commenced a program during 2010 to significantly transform our IT organization and delivery model. The total costs for this program were $37 million, of which $36 million were incurred in 2010. The savings resulting from this program are being reinvested in IT and other property and casualty underwriting areas necessary to support our business strategies.

Favorable net prior year development of $431 million and $594 million was recorded in 2011 and 2010 related to our CNA Specialty, CNA Commercial and Corporate & Other Non-Core segments. Further information on net prior year development for 2011 and 2010 is included in Note G to the Consolidated Financial Statements included under Item 8.

Net earned premiums increased $88 million in 2011 as compared with 2010 driven by a $117 million increase in CNA Specialty. See the Segment Results section of this MD&A for further discussion.

Net loss from discontinued operations decreased $20 million in 2011 as compared to 2010 due to the loss associated with the Loss Portfolio Transfer in 2010.

CRITICAL ACCOUNTING ESTIMATES

The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (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 Consolidated Financial Statements and the amounts of revenues and expenses reported during the period. Actual results may differ from those estimates.

Our 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 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 discussed below are considered by us to be critical to an understanding of our Consolidated Financial Statements as their application places the most significant demands on our judgment. Note A to the Consolidated Financial Statements included under Item 8 should be read in conjunction with this section to assist with obtaining an understanding of the underlying accounting policies related to these estimates. Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from estimates and may have a material adverse impact on our results of operations or equity.

Insurance reserves are established for both short and long-duration insurance contracts. Short-duration contracts are primarily related to property and casualty insurance policies where the reserving process is based on actuarial estimates of the amount of loss, including amounts for known and unknown claims. Long-duration contracts include long term care products and payout annuity contracts and are estimated using actuarial estimates about mortality, morbidity and persistency as well as assumptions about expected investment returns. The reserve for unearned premiums on property and casualty contracts represents the portion of premiums written related to the unexpired terms of coverage. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.

Reinsurance and Insurance Receivables

An exposure exists with respect to the collectibility of ceded property and casualty and life reinsurance to the extent that any reinsurer is unable to meet its obligations or disputes the liabilities we have ceded under reinsurance agreements. An allowance for uncollectible reinsurance is recorded on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, our past experience and current economic conditions. Further information on our reinsurance receivables is included in Note I to the Consolidated Financial Statements included under Item 8.

Additionally, an exposure exists with respect to the collectibility of amounts due from policyholders related to insurance contracts, including amounts due from insureds under high deductible policies. An allowance for uncollectible insurance receivables is recorded on the basis of periodic evaluations of balances due from insureds currently or in the future, management's experience and current economic conditions.

If actual experience differs from the estimates made by management in determining the allowances for uncollectible reinsurance and insurance receivables, net receivables as reflected on our Consolidated Balance Sheets may not be collected. Therefore, our results of operations or equity could be materially adversely impacted.

21

Valuation of Investments and Impairment of Securities

We classify our fixed maturity securities and equity securities as either available-for-sale or trading which are both carried at fair value on the balance sheet. Fair value represents the price that would be received in a sale of an asset in an orderly transaction between market participants on the measurement date, the determination of which requires us to make a significant number of assumptions and judgments. Securities with the greatest level of subjectivity around valuation are those that rely on inputs that are significant to the estimated fair value and that are not observable in the market or cannot be derived principally from or corroborated by observable market data. These unobservable inputs are based on assumptions consistent with what we believe other market participants would use to price such securities. Further information on our fair value measurements is included in Note E to the Consolidated Financial Statements included under Item 8.

Our investment portfolio is subject to market declines below amortized cost that may be other-than-temporary and therefore result in the recognition of impairment losses in earnings. Factors considered in the determination of whether or not a decline is other-than-temporary include a current intention or need to sell the security or an indication that a credit loss exists. Significant judgment exists regarding the evaluation of the financial condition and expected near-term and long-term prospects of the issuer, the relevant industry conditions and trends, and whether we expect to receive cash flows sufficient to recover the entire amortized cost basis of the security. We have an Impairment Committee which reviews the investment portfolio on at least a quarterly basis, with ongoing analysis as new information becomes available. Further information on our process for evaluating impairments is included in Note C to the Consolidated Financial Statements included under Item 8.

Long Term Care Products and Payout Annuity Contracts

Future policy benefit reserves for our long term care products and payout annuity contracts are based on certain assumptions including morbidity, mortality, policy persistency, and discount rates, which are impacted by expected investment yields. The adequacy of the reserves are contingent on actual experience related to these key assumptions, which were generally established at time of issue. If actual experience differs from these assumptions, the reserves may not be adequate, requiring us to add to reserves. Therefore, our results of operations or equity could be adversely impacted. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.

Pension and Postretirement Benefit Obligations

We make a significant number of assumptions in estimating the liabilities and costs related to our pension and postretirement benefit obligations under our benefit plans. The assumptions that most impact these costs are the discount rate and the expected long term rate of return on plan assets. These assumptions are evaluated relative to current economic factors such as inflation, interest rates and fiscal and monetary policies. Changes in these assumptions can have a material impact on pension obligations and pension expense.

To determine the discount rate assumption as of the year-end measurement date for our CNA Retirement Plan and CNA Health and Group Benefits Program, we considered the estimated timing of plan benefit payments and available yields on high quality fixed income debt securities. For this purpose, high quality is considered a rating of Aa or better by Moody's or a rating of AA or better from S&P. We reviewed several yield curves constructed using the cash flow characteristics of the plans as well as bond indices as of the measurement date. The year-over-year change of those data points was also considered.

In determining the expected long term rate of return on plan assets assumption for our CNA Retirement Plan, we considered the historical performance of the investment portfolio as well as the long term market return expectations based on the investment mix of the portfolio.

Further information on our pension and postretirement benefit obligations is included in Note K to the Consolidated Financial Statements included under Item 8.

22

Income Taxes

We account for income taxes under the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial statement and tax return basis of assets and liabilities. Any resulting future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized. The assessment of the need for a valuation allowance requires management to make estimates and assumptions about future earnings, reversal of existing temporary differences and available tax planning strategies. If actual experience differs from these estimates and assumptions, the recorded deferred tax asset may not be fully realized resulting in an increase to income tax expense in our results of operations. In addition, the ability to record deferred tax assets in the future could be limited, resulting in a higher effective tax rate in that future period.

RESERVES - ESTIMATES AND UNCERTAINTIES

Property and Casualty Claim and Claim Adjustment Expense Reserves

We maintain loss reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for claims that have been reported but not yet settled (case reserves) and claims that have been incurred but not reported (IBNR). Claim and claim adjustment expense reserves are reflected as liabilities and are included on the Consolidated Balance Sheets under the heading “Insurance Reserves.” Adjustments to prior year reserve estimates, if necessary, are reflected in results of operations in the period that the need for such adjustments is determined. The carried case and IBNR reserves as of each balance sheet date are provided in the Segment Results section of this MD&A and in Note G to the Consolidated Financial Statements included under Item 8.

The level of reserves we maintain represents our best estimate, as of a particular point in time, of what the ultimate settlement and administration of claims will cost based on our assessment of facts and circumstances known at that time. Reserves are not an exact calculation of liability but instead are complex estimates that we derive, generally utilizing a variety of actuarial reserve estimation techniques, from numerous assumptions and expectations about future events, both internal and external, many of which are highly uncertain.

We are subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on our business by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims. Examples of emerging or potential claims and coverage issues include:

• the effects of worldwide economic conditions, which have resulted in an increase in the number and size of certain claims, including both D&O and E&O insurance claims related to corporate failures, as well as other coverages;

• class action litigation relating to claims handling and other practices; and

• mass tort claims, including bodily injury claims related to welding rods, benzene, lead, noise induced hearing loss, injuries from various medical products including pharmaceuticals, and various other chemical and radiation exposure claims.

The impact of these and other unforeseen emerging or potential claims and coverage issues is difficult to predict and could materially adversely affect the adequacy of our claim and claim adjustment expense reserves and could lead to future reserve additions.

Our property and casualty insurance subsidiaries also have actual and potential exposures related to A&EP claims. Our experience has been that establishing reserves for casualty coverages relating to A&EP claims and the related claim adjustment expenses are subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims are subject to a higher degree of variability.

To mitigate the risks posed by our exposure to A&EP claims and claim adjustment expenses, as further discussed in Note G to the Consolidated Financial Statements included under Item 8, on August 31, 2010 we completed a transaction with NICO, a subsidiary of Berkshire Hathaway Inc., under which substantially all of our legacy A&EP liabilities were ceded to NICO effective January 1, 2010 (Loss Portfolio Transfer).

The Loss Portfolio Transfer is considered a retroactive reinsurance contract. In the event that the cumulative claim and allocated claim adjustment expenses ceded under the Loss Portfolio Transfer exceed the consideration paid, the resulting gain from such excess would be deferred. A cumulative amortization adjustment would be recognized in earnings in the period such excess arises so that the resulting deferred gain would reflect the balance that would have existed if the revised estimate was available at the inception date of the Loss Portfolio Transfer. This accounting generally results in a reserve charge because of the timing difference between the recognition of the gross adverse reserve development and the related ceded reinsurance benefit. However, there is no economic impact as long as

24

the additional losses are within the limit under the contract. Any future adverse prior year development in excess of approximately $230 million would put the Loss Portfolio Transfer into an overall gain position under retroactive reinsurance accounting.

Establishing Reserve Estimates

In developing claim and claim adjustment expense ("loss" or "losses") reserve estimates, our actuaries perform detailed reserve analyses that are staggered throughout the year. The data is organized at a "product" level. A product can be a line of business covering a subset of insureds such as commercial automobile liability for small or middle market customers, it can encompass several lines of business provided to a specific set of customers such as dentists, or it can be a particular type of claim such as construction defect. Every product is analyzed at least once during the year, with the exception of certain run-off products which are analyzed on a periodic basis. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. In addition to the detailed analyses, we review actual loss emergence for all products each quarter.

The detailed analyses use a variety of generally accepted actuarial methods and techniques to produce a number of estimates of ultimate loss. Our actuaries determine a point estimate of ultimate loss by reviewing the various estimates and assigning weight to each estimate given the characteristics of the product being reviewed. The reserve estimate is the difference between the estimated ultimate loss and the losses paid to date. The difference between the estimated ultimate loss and the case incurred loss (paid loss plus case reserve) is IBNR. IBNR calculated as such includes a provision for development on known cases (supplemental development) as well as a provision for claims that have occurred but have not yet been reported (pure IBNR).

Most of our business can be characterized as long-tail. For long-tail business, it will generally be several years between the time the business is written and the time when all claims are settled. Our long-tail exposures include commercial automobile liability, workers' compensation, general liability, medical professional liability, other professional liability coverages, assumed reinsurance run-off and products liability. Short-tail exposures include property, commercial automobile physical damage, marine and warranty. CNA Specialty and CNA Commercial contain both long-tail and short-tail exposures. Hardy contains primarily short-tail exposures. Corporate & Other Non-Core contains long-tail exposures.

Various methods are used to project ultimate loss for both long-tail and short-tail exposures including, but not limited to, the following:

•paid development;

•incurred development;

•loss ratio;

•Bornhuetter-Ferguson using paid loss;

•Bornhuetter-Ferguson using incurred loss;

•frequency times severity; and

•stochastic modeling.

The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident or policy years with further expected changes in paid loss. Selection of the paid loss pattern may require consideration of several factors including the impact of inflation on claims costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, the impact of underwriting changes, the impact of large claim payments and other factors. Claim cost inflation itself may require evaluation of changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors. Because this method assumes that losses are paid at a consistent rate, changes in any of these factors can impact the results. Since the method does not rely on case reserves, it is not directly influenced by changes in the adequacy of case reserves.

For many products, paid loss data for recent periods may be too immature or erratic for accurate predictions. This situation often exists for long-tail exposures. In addition, changes in the factors described above may result in

25

inconsistent payment patterns. Finally, estimating the paid loss pattern subsequent to the most mature point available in the data analyzed often involves considerable uncertainty for long-tail products such as workers' compensation.

The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses.  Since the method uses more data (case reserves in addition to paid losses) than the paid development method, the incurred development patterns may be less variable than paid patterns. However, selection of the incurred loss pattern typically requires analysis of all of the same factors described above. In addition, the inclusion of case reserves can lead to distortions if changes in case reserving practices have taken place, and the use of case incurred losses may not eliminate the issues associated with estimating the incurred loss pattern subsequent to the most mature point available.

The loss ratio method multiplies earned premiums by an expected loss ratio to produce ultimate loss estimates for each accident or policy year. This method may be useful for immature accident or policy periods or if loss development patterns are inconsistent, losses emerge very slowly, or there is relatively little loss history from which to estimate future losses. The selection of the expected loss ratio typically requires analysis of loss ratios from earlier accident or policy years or pricing studies and analysis of inflationary trends, frequency trends, rate changes, underwriting changes, and other applicable factors.

The Bornhuetter-Ferguson method using paid loss is a combination of the paid development method and the loss ratio method. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method and typically requires analysis of the same factors described above. This method assumes that future losses will develop at the expected loss ratio level. The percent of paid loss to ultimate loss implied from the paid development method is used to determine what percentage of ultimate loss is yet to be paid. The use of the pattern from the paid development method typically requires consideration of the same factors listed in the description of the paid development method. The estimate of losses yet to be paid is added to current paid losses to estimate the ultimate loss for each year. For long-tail lines, this method will react very slowly if actual ultimate loss ratios are different from expectations due to changes not accounted for by the expected loss ratio calculation.

The Bornhuetter-Ferguson method using incurred loss is similar to the Bornhuetter-Ferguson method using paid loss except that it uses case incurred losses. The use of case incurred losses instead of paid losses can result in development patterns that are less variable than paid patterns. However, the inclusion of case reserves can lead to distortions if changes in case reserving have taken place, and the method typically requires analysis of the same factors that need to be reviewed for the loss ratio and incurred development methods.

The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident or policy year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for products where loss development patterns are inconsistent or too variable to be relied on exclusively. In addition, this method can more directly account for changes in coverage that impact the number and size of claims. However, this method can be difficult to apply to situations where very large claims or a substantial number of unusual claims result in volatile average claim sizes. Projecting the ultimate number of claims may require analysis of several factors including the rate at which policyholders report claims to us, the impact of judicial decisions, the impact of underwriting changes and other factors. Estimating the ultimate average loss may require analysis of the impact of large losses and claim cost trends based on changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors.

Stochastic modeling produces a range of possible outcomes based on varying assumptions related to the particular product being modeled. For some products, we use models which rely on historical development patterns at an aggregate level, while other products are modeled using individual claim variability assumptions supplied by the claims department. In either case, multiple simulations are run and the results are analyzed to produce a range of potential outcomes. The results will typically include a mean and percentiles of the possible reserve distribution which aid in the selection of a point estimate.

For many exposures, especially those that can be considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a

26

case, our actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method.  For most of our products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, we will not assign any weight to the paid and incurred development methods. We will use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods.  For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because our history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, we may also use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods for short-tail exposures.

For other more complex products where the above methods may not produce reliable indications, we use additional methods tailored to the characteristics of the specific situation.

Periodic Reserve Reviews

The reserve analyses performed by our actuaries result in point estimates. Each quarter, the results of the detailed reserve reviews are summarized and discussed with our senior management to determine the best estimate of reserves. This group considers many factors in making this decision. The factors include, but are not limited to, the historical pattern and volatility of the actuarial indications, the sensitivity of the actuarial indications to changes in paid and incurred loss patterns, the consistency of claims handling processes, the consistency of case reserving practices, changes in our pricing and underwriting, pricing and underwriting trends in the insurance market, and legal, judicial, social and economic trends.

Our recorded reserves reflect our best estimate as of a particular point in time based upon known facts, consideration of the factors cited above, and our judgment. The carried reserve may differ from the actuarial point estimate as the result of our consideration of the factors noted above as well as the potential volatility of the projections associated with the specific product being analyzed and other factors impacting claims costs that may not be quantifiable through traditional actuarial analysis. This process results in management's best estimate which is then recorded as the loss reserve.

Currently, our recorded reserves are modestly higher than the actuarial point estimate. For CNA Commercial, CNA Specialty and Hardy, the difference between our reserves and the actuarial point estimate is primarily driven by uncertainty with respect to immature accident years,claim cost inflation, changes in claims handling, tort reform roll-backs which may adversely impact claim costs, and the effects from the economy. For Corporate & Other Non-Core, the difference between our reserves and the actuarial point estimate is primarily driven by the potential tail volatility of run-off exposures.

The key assumptions fundamental to the reserving process are often different for various products and accident or policy years. Some of these assumptions are explicit assumptions that are required of a particular method, but most of the assumptions are implicit and cannot be precisely quantified. An example of an explicit assumption is the pattern employed in the paid development method. However, the assumed pattern is itself based on several implicit assumptions such as the impact of inflation on medical costs and the rate at which claim professionals close claims. As a result, the effect on reserve estimates of a particular change in assumptions typically cannot be specifically quantified, and changes in these assumptions cannot be tracked over time.

Our recorded reserves are management's best estimate. In order to provide an indication of the variability associated with our net reserves, the following discussion provides a sensitivity analysis that shows the approximate estimated impact of variations in significant factors affecting our reserve estimates for particular types of business. These significant factors are the ones that we believe could most likely materially impact the reserves. This discussion covers the major types of business for which we believe a material deviation to our reserves is reasonably possible. There can be no assurance that actual experience will be consistent with the current assumptions or with the variation indicated by the discussion. In addition, there can be no assurance that other factors and assumptions will not have a material impact on our reserves.

Within CNA Specialty, we believe a material deviation to our net reserves is reasonably possible for professional liability and related business. This business includes professional liability coverages provided to various professional firms, including architects, real estate agents, small and mid-sized accounting firms, law firms and

27

technology firms. This business also includes D&O, employment practices, fiduciary, fidelity and surety coverages, as well as insurance products serving the healthcare delivery system. The most significant factor affecting reserve estimates for this business is claim severity. Claim severity is driven by the cost of medical care, the cost of wage replacement, legal fees, judicial decisions, legislative changes and other factors. Underwriting and claim handling decisions such as the classes of business written and individual claim settlement decisions can also impact claim severity. If the estimated claim severity increases by 9%, we estimate that the net reserves would increase by approximately $500 million. If the estimated claim severity decreases by 3%, we estimate that net reserves would decrease by approximately $150 million. Our net reserves for this business were approximately $5.3 billion at December 31, 2012.

Within CNA Commercial, the two types of business for which we believe a material deviation to our net reserves is reasonably possible are workers' compensation and general liability.

For CNA Commercial workers' compensation, since many years will pass from the time the business is written until all claim payments have been made, claim cost inflation on claim payments is the most significant factor affecting workers' compensation reserve estimates. Workers' compensation claim cost inflation is driven by the cost of medical care, the cost of wage replacement, expected claimant lifetimes, judicial decisions, legislative changes and other factors. If estimated workers' compensation claim cost inflation increases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would increase by approximately $450 million. If estimated workers' compensation claim cost inflation decreases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would decrease by approximately $400 million. Our net reserves for CNA Commercial workers' compensation were approximately $4.9 billion at December 31, 2012.

For CNA Commercial general liability, the most significant factor affecting reserve estimates is claim severity. Claim severity is driven by changes in the cost of repairing or replacing property, the cost of medical care, the cost of wage replacement, judicial decisions, legislation and other factors. If the estimated claim severity for general liability increases by 6%, we estimate that our net reserves would increase by approximately $250 million. If the estimated claim severity for general liability decreases by 3%, we estimate that our net reserves would decrease by approximately $100 million. Our net reserves for CNA Commercial general liability were approximately $3.8 billion at December 31, 2012.

Given the factors described above, it is not possible to quantify precisely the ultimate exposure represented by claims and related litigation. As a result, we regularly review the adequacy of our reserves and reassess our reserve estimates as historical loss experience develops, additional claims are reported and settled and additional information becomes available in subsequent periods.

In light of the many uncertainties associated with establishing the estimates and making the assumptions necessary to establish reserve levels, we review our reserve estimates on a regular basis and make adjustments in the period that the need for such adjustments is determined. These reviews have resulted in our identification of information and trends that have caused us to change our reserves in prior periods and could lead to the identification of a need for additional material increases or decreases in claim and claim adjustment expense reserves, which could materially affect our results of operations, equity, business and insurer financial strength and corporate debt ratings positively or negatively. See the Ratings section of this MD&A for further information regarding our financial strength and corporate debt ratings.

Life & Group Non-Core Policyholder Reserves

We calculate and maintain reserves for policyholder claims and benefits for our Life & Group Non-Core segment based on actuarial assumptions. The determination of these reserves is fundamental to our financial results and requires management to make assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk.

The actuarial assumptions represent management's best estimate at the date the contract was issued plus a margin for adverse deviation. Actuarial assumptions include estimates of morbidity, mortality, policy persistency, discount rates and expenses over the life of the contracts. Under GAAP, these assumptions are locked in throughout the life of the contract unless a premium deficiency develops. The impact of differences between the actuarial

28

assumptions and actual experience is reflected in results of operations each period.

Annually, management assesses the adequacy of its GAAP reserves by product group by performing premium deficiency testing. In this test, reserves computed using best estimate assumptions as of the date of the test without provisions for adverse deviation are compared to the recorded reserves. If reserves determined based on management's current best estimate assumptions are greater than the existing net GAAP reserves (i.e. reserves net of any Deferred acquisition costs asset), the existing net GAAP reserves are adjusted to the greater amount.

Payout Annuity Reserves

Our payout annuity reserves consist primarily of single premium group and structured settlement annuities. The annuity payments are generally fixed and are either for a specified period or contingent on the survival of the payee. These reserves are discounted except for reserves for loss adjustment expenses on structured settlements not funded by annuities in our property and casualty insurance companies. In 2012 and 2011, we recognized a premium deficiency on our payout annuity reserves. Therefore, the actuarial assumptions established at time of issue have been unlocked and updated to management's then current best estimate. The actuarial assumptions that management believes are subject to the most variability are discount rates and mortality.

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group. Although such hypothetical revisions are not currently required or anticipated, we believe they could occur based on past variances in experience and our expectations of the ranges of future experience that could reasonably occur.

Sensitivity Analysis

December 31, 2012
	Estimated reduction
Hypothetical revisions (In millions)	to pretax income
Discount rate:
50 basis point decline	$	131
100 basis point decline	$	277
Mortality:
5% decline	$	25
10% decline	$	51

Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized above.

Long Term Care Reserves

Long term care policies provide benefits for nursing home, assisted living and home health care subject to various daily and lifetime caps. Policyholders must continue to make periodic premium payments to keep the policy in force. Generally we have the ability to increase policy premiums, subject to state regulatory approval.

Our long term care reserves consist of an active life reserve, a liability for due and unpaid claims, claims in the course of settlement and incurred but not reported claims. The active life reserve represents the present value of expected future benefit payments and expenses less expected future premium.

The actuarial assumptions that management believes are subject to the most variability are discount rates, morbidity, and persistency, which can be affected by policy lapses and death. The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group. Although such hypothetical revisions are not currently required or anticipated, we believe they could occur based on past variances in experience and our expectations of the ranges of future experience that could reasonably occur.

29

It should be noted that our current GAAP long term care reserves contain a level of margin in excess of management's current best estimates. Any required increase in the net GAAP reserves resulting from the hypothetical revisions in the table below would first reduce the margin before they would affect results of operations. The estimated impact to results of operations in the table below are after consideration of the existing margin.

Sensitivity Analysis

December 31, 2012
	Estimated reduction
Hypothetical revisions (In millions)	to pretax income
Discount rate:
50 basis point decline	$	491
100 basis point decline	$	1,221
Morbidity:
5% increase	$	357
10% increase	$	869
Persistency:
5% decline in voluntary lapse and mortality	$	208
10% decline in voluntary lapse and mortality	$	607

Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized above.

SEGMENT RESULTS

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

Our core property and casualty commercial insurance operations are reported in three business segments: CNA Specialty, CNA Commercial and Hardy. CNA Specialty provides a broad array of professional, financial and specialty property and casualty products and services, primarily through insurance brokers and managing general underwriters. CNA Commercial includes property and casualty coverages sold to small businesses and middle market entities and organizations primarily through an independent agency distribution system. CNA Commercial also includes commercial insurance and risk management products sold to large corporations primarily through insurance brokers. Hardy underwrites primarily short-tail exposures in marine and aviation, non-marine property, specialty lines and property treaty reinsurance. The Company acquired Hardy on July 2, 2012. Further information on Hardy is set forth in Note B.

Our non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core. Life & Group Non-Core primarily includes the results of the life and group lines of business that are in run-off. Corporate & Other Non-Core primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP. Intersegment eliminations are also included in this segment.

Our property and casualty field structure consists of 49 underwriting locations across the United States. In addition, there are five centralized processing operations which handle policy processing, billing and collection activities, and also act as call centers to optimize service. The claims structure consists of two regional claim centers designed to efficiently handle the high volume of low severity claims including property damage, liability, and workers' compensation medical only claims, and 16 principal claim offices handling the more complex claims. In addition, we have underwriting and claim capabilities in Canada and Europe.

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 O to the Consolidated Financial Statements included under Item 8. 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 Consolidated Financial Statements included under Item 8.

2012 Compared with 2011

Net written premiums for CNA Specialty increased $52 million in 2012 as compared with 2011, primarily driven by positive rate achievement, partially offset by lower new business levels in certain lines.

Net operating income decreased $13 million in 2012 as compared with 2011, primarily due to decreased favorable net prior year development and decreased current accident year underwriting results, partially offset by higher investment income and the inclusion of our Surety business on a wholly-owned basis in 2012.

The combined ratio increased 4.9 points in 2012 as compared with 2011. The loss ratio increased 3.9 points, primarily due to decreased favorable net prior year development as well as the impact of a higher current accident year loss ratio.

CNA Commercial

Business Overview

CNA Commercial works with an independent agency distribution system and a network of brokers to market a broad range of property and casualty insurance products and services to small, middle-market and large businesses and organizations domestically and abroad. Property products include standard and excess property coverages, as well as marine coverage, and boiler and machinery. Casualty products include standard casualty insurance products such as workers' compensation, general and product liability, commercial auto and umbrella coverages. Most insurance programs are provided on a guaranteed cost basis; however, we also offer specialized loss-sensitive insurance programs to those customers viewed as higher risk and less predictable in exposure.

These property and casualtyproducts are offered as part of our SmallBusiness,Commercial and International insurance groups. Our Small Business insurance group serves our smaller commercial accounts and the Commercial insurance group serves our middle markets and larger risks. In addition, CNA Commercial provides total risk management services relating to claim and information services to the large commercial insurance marketplace, through a wholly-owned subsidiary, CNA ClaimPlus, Inc., a third party administrator.The International insurance group primarily consists of the commercial product lines of our operations in Europe and Canada. During the fourth quarter of 2011, we sold our 50% ownership interest in First Insurance Company of Hawaii (FICOH).

Also included in CNA Commercial is CNA Select Risk (Select Risk),which includes our excess and surplus lines coverages. Select Risk provides specialized insurance for selected commercial risks on both an individual customer and program basis. Customers insured by Select Risk are generally viewed as higher risk and less predictable in exposure than those covered by standard insurance markets. Select Risk's products are distributed throughout the United States through specialist producers, program agents and brokers.

2012 Compared with 2011

Net written premiums for CNA Commercial increased $23 million in 2012 as compared with 2011. Net written premiums for 2011 included $128 million related to FICOH. Excluding FICOH, the increase in net written premiums was primarily driven by positive rate achievement. Net earned premiums increased $66 million in 2012 as compared with 2011. Net earned premium for 2011 included $125 million related to FICOH. Excluding FICOH, the increase in net earned premiums was driven by the increase in net written premiums and the impact of favorable premium development in 2012 as compared with unfavorable premium development in 2011.

CNA Commercial's average rate increased 7% in 2012, as compared with an increase of 2% in 2011 for the policies that renewed in each period. Retention of 78% was achieved in each period.

35

Net income decreased $77 million in 2012 as compared with 2011. This decrease was due to lower net operating income, partially offset by improved net realized investment results.

Net operating income decreased $90 million in 2012 as compared with 2011. This decrease was primarily due to higher catastrophe losses and decreased favorable net prior year development. These unfavorable impacts were partially offset by higher net investment income, as well as the tax expense item in 2011 discussed below.

The combined ratio increased 7.7 points in 2012 as compared with 2011. The loss ratio increased 7.0 points, primarily due to the impacts of higher catastrophe losses and decreased favorable net prior year development, partially offset by an improved current accident year non-catastrophe loss ratio. Catastrophe losses were $356 million, or 10.9 points of the loss ratio, for 2012, as compared to $208 million, or 6.4 points of the loss ratio, for 2011. Catastrophe losses in 2012 included $241 million related to Storm Sandy.

The expense ratio increased 0.7 points in 2012 as compared with 2011, primarily due to the favorable impact of recoveries in 2011 on insurance receivables written off in prior years.

Favorable net prior year development of $81 million and $183 million was recorded in 2012 and 2011. Further information on CNA Commercial net prior year development for 2012 and 2011 is included in Note G to the Consolidated Financial Statements included under Item 8.

2011 Compared with 2010

Net written premiums for CNA Commercial increased $142 million in 2011 as compared with 2010. This increase was driven by continued positive rate achievement, improved economic conditions reflected in insured exposures, as well as lower reinsurance costs and higher new business levels in certain business lines.

CNA Commercial's average rate increased 2% for 2011, as compared with an increase of 1% in 2010 for the policies that renewed during those periods. Retention of 78% and 80% was achieved in each period.

Net income decreased $118 million in 2011 as compared with 2010. This decrease was due to lower net operating income, partially offset by improved net realized investment results.

Net operating income decreased $147 million in 2011 as compared with 2010. This decrease was primarily due to lower net investment income, higher catastrophe losses and lower favorable net prior year development. In addition, income tax expense of $22 million was recorded in the third quarter of 2011 due to an increase in the tax rate applicable to the undistributed earnings of a 50% owned subsidiary which was sold later in 2011. The sale resulted in a modest after-tax loss inclusive of this income tax expense. These unfavorable impacts were partially offset by improved non-catastrophe current accident year underwriting results, including lower expenses. In 2010, expenses were unfavorably impacted by IT transformation costs, as further discussed in Note P to the Consolidated Financial Statements included under Item 8.

36

The combined ratio increased 3.2 points in 2011 as compared with 2010. The loss ratio increased 4.1 points, primarily due to lower favorable net prior year development and higher catastrophe losses, partially offset by an improved current accident year non-catastrophe loss ratio. Catastrophe losses were $208 million, or 6.4 points of the loss ratio for 2011, as compared to $113 million, or 3.5 points of the loss ratio, for 2010.

The expense ratio improved 0.8 points in 2011 as compared with 2010, primarily due to the favorable impact of recoveries in 2011 on insurance receivables written off in prior years and the impact of IT Transformation costs incurred in 2010, as discussed above.

Favorable net prior year development of $183 million and $256 million was recorded in 2011 and 2010. Further information on CNA Commercial net prior year development for 2011 and 2010 is included in Note G to the Consolidated Financial Statements included under Item 8.

Life & Group Non-Core

Business Overview

The Life & Group Non-Core segment primarily includes the results of the life and group lines of business that are in run-off. We continue to service our existing individual long term care commitments, our payout annuity business and our pension deposit business. We also retain a block of group reinsurance and life settlement contracts. These businesses are being managed as a run-off operation. Our group long term care business, while considered non-core, continues to accept new employees in existing groups.

The following table summarizes the results of operations for Life & Group Non-Core.

2012 Compared with 2011

Net earned premiums for Life & Group Non-Core decreased $9 million in 2012 as compared with 2011. Net earned premiums relate primarily to the individual and group long term care businesses. The decrease in earned premiums was primarily due to lapsing of policies in our individual long term care business, which is in run-off, partially offset by increased premiums resulting from rate increase actions related to this business.

Net loss decreased $123 million in 2012 as compared with 2011. The results included the unfavorable impact of a $24 million after-tax charge in 2012 as compared to a $115 million after-tax charge in 2011 related to our payout annuity business, due to unlocking actuarial reserve assumptions. The initial reserving assumptions for these contracts were determined at issuance, including a margin for adverse deviation, and were locked in throughout the life of the contract unless a premium deficiency developed. The increase to the related reserves in 2012 related to anticipated adverse changes in discount rates, which reflect the current low interest rate environment and our view of expected future investment yields. The increase in 2011 related to anticipated adverse changes in mortality and discount rates. Additionally, long term care claim reserves were increased by $20 million after-tax in 2012 and $33 million after-tax in 2011.

The decrease in net loss was also driven by improved results in our life settlement contracts business and the impact of unfavorable performance in 2011 on our remaining pension deposit business.

2011 Compared with 2010

Net earned premiums for Life & Group Non-Core decreased $13 million in 2011 as compared with 2010. Net earned premiums relate primarily to the individual and group long term care businesses.

Net loss increased $157 million in 2011 as compared with 2010 due to decreased results in our payout annuity, pension deposit and long term care businesses. In 2011, our payout annuity business was negatively impacted by a $115 million after-tax increase in insurance reserves, as discussed above. In 2010, our payout annuity reserves were increased by $39 million pretax and after-tax, resulting from unlocking assumptions. Additionally, long term care claim reserves were increased by $33 million after-tax in 2011.

A number of our separate account pension deposit contracts guarantee principal and an annual minimum rate of interest. If aggregate contract value in the separate account exceeds the fair value of the related assets, an additional Policyholders' funds liability is established. During 2011, we increased this pretax liability by $18 million. During 2010, we decreased this pretax liability by $24 million.

Additionally, the increase in net loss was driven by decreased net realized investment results. The increase in net loss was further driven by favorable reserve development arising from a commutation of an assumed reinsurance agreement in 2010. These unfavorable impacts were partially offset by decreased expenses. In 2010, expenses were unfavorably impacted by the IT transformation costs, as further discussed in Note P to the Consolidated Financial Statements included under Item 8.

Corporate & Other Non-Core

Overview

Corporate & Other Non-Core primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP. In 2010, we ceded substantially all of our legacy A&EP liabilities under the Loss Portfolio Transfer, as further discussed in Note G to the Consolidated Financial Statements included under Item 8.

The following table summarizes the results of operations for the Corporate & Other Non-Core segment, including A&EP and intersegment eliminations.

2012 Compared with 2011

Net loss increased $10 million in 2012 as compared with 2011, primarily driven by the favorable impact in 2011 of a prior year tax amount as discussed later in this section, partially offset by increased favorable net prior year development and improved net realized investment results.

Favorable net prior year development of $12 million and $3 million was recorded in 2012 and 2011.

The following table summarizes the gross and net carried reserves as of December 31, 2012 and 2011 for Corporate & Other Non-Core.

42

2011 Compared with 2010

Net loss decreased $305 million in 2011 as compared with 2010, primarily driven by the after-tax loss of $344 million as a result of the Loss Portfolio Transfer consummated in the third quarter of 2010. As a result of that transaction, the investment income allocated to the Corporate & Other Non-Core segment decreased substantially because of the lower net reserve base and associated risk capital. Claim adjustment expenses are lower because the counterparty to the Loss Portfolio Transfer is responsible for A&EP claim handling. The A&EP operations produced net operating income of $23 million for 2010.

Additionally, the decrease in net loss was driven by the favorable impact of a $22 million prior year tax amount and a $15 million pretax release of a previously established allowance for uncollectible reinsurance receivables arising from a change in estimate. These favorable impacts were partially offset by decreased net realized investment results and higher interest expense. The increase in interest expense primarily relates to the use of debt to fund a portion of the 2010 redemption of our preferred stock.

Favorable net prior year development of $3 million was recorded in 2011, compared to unfavorable net prior development of $6 million in 2010.

INVESTMENTS

Net Investment Income

The significant components of pretax net investment income are presented in the following table.

Net Investment Income

Years ended December 31
(In millions)	2012			2011			2010
Fixed maturity securities	$	2,022		$	2,011		$	2,051

Investment expense	(56		)	(58		)	(54		)
Net investment income	$	2,282		$	2,054		$	2,316

Net investment income for the year ended December 31, 2012 increased $228 million as compared with the same period in 2011. The increase was primarily driven by a significant increase in limited partnership investment income, increased trading portfolio income and an increase in fixed maturity securities income. Limited partnership results were positively impacted by more favorable equity market returns, and overall capital market and credit spread volatility. The increase in fixed maturity securities income was driven by a higher invested asset base and the 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.

Net investment income decreased $262 million in 2011 as compared with 2010. The decrease was primarily driven by a significant decrease in limited partnership results as well as lower fixed maturity security income. Limited partnership results were adversely impacted by less favorable equity market returns, and overall capital market and credit spread volatility. The decrease in fixed maturity security income was primarily driven by the effect of purchasing new investments at lower market interest rates.

The fixed maturity investment portfolio provided a pretax effective income yield of 5.3%, 5.5% and 5.6% for the years ended December 31, 2012, 2011 and 2010. Tax-exempt municipal bonds generated $274 million of net investment income for the year ended December 31, 2012 compared with $240 million and $263 million of net investment income for the same periods in 2011 and 2010.

Net realized investment gains increased $38 million for 2012 as compared with 2011, driven by lower other-than-temporary impairment (OTTI) losses recognized in earnings. Net realized investment gains decreased $48 million for 2011 as compared with 2010. Net realized investment results include OTTI losses of $100 million, $140 million, and $151 million for 2012, 2011, and 2010. Further information on our realized gains and losses, including our OTTI losses and impairment decision process, is set forth in Note C to the Consolidated Financial Statements included under Item 8.

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 December 31, 2012 and 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 December 31, 2012 and 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.

Non-investment grade	3,567		8		3,159		8
Total	$	42,633	100	%	$	39,937	100	%

Non-investment grade fixed maturity securities, as presented in the table below, include high-yield securities rated below BBB- by bond rating agencies and other unrated securities that, according to our analysis, are below investment grade. Non-investment grade securities generally involve a greater degree of risk than investment grade securities. The amortized cost of our non-investment grade fixed maturity bond portfolio was $3,355 million and $3,200 million at December 31, 2012 and 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.

Effective Durations

	December 31, 2012			December 31, 2011
(In millions)	Fair Value		Effective Duration (In years)	Fair Value		Effective Duration (In years)
Investments supporting Life & Group Non-Core	$	15,590	11.3	$	13,820	11.5
Other interest sensitive investments	28,855		3.9	28,071		3.9
Total	$	44,445	6.5	$	41,891	6.4

The investment portfolio is periodically analyzed for changes in duration and related price risk. Additionally, we periodically review the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes. A summary of these risks and specific analysis on changes is included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk included herein.

Total amortized cost	$	1,615	$	2,027	$	161	$	3,803

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. As of December 31, 2012, securities with a fair value and amortized cost of $2,034 million and $1,830 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 $324 million and $298 million pertain to Greece, Italy, Ireland, Portugal and Spain, commonly referred to as “GIIPS.”

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

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

For 2012, net cash provided by operating activities was $1,250 million as compared with $1,702 million for 2011. Cash flows resulting from reinsurance contract commutations are reported as operating activities. During 2012, operating cash flows were decreased by $30 million related to net cash outflows from commutations as compared with net cash inflows of $547 million during 2011. Additionally, we received a $29 million tax refund in 2012 as compared to tax payments of $61 million in 2011.

Net cash used by operating activities was $89 million in 2010. As further discussed in Note G to the Consolidated Financial Statements included under Item 8 and previously referenced in this MD&A, in 2010 we completed the Loss Portfolio Transfer transaction. As a result of this transaction, operating cash flows were reduced for the initial net cash settlement with NICO. Excluding the impact of this transaction, net cash provided by operating activities was approximately $1,800 million for 2010.

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

Net cash used by investing activities was $934 million for 2012, as compared with net cash used of $1,060 million for 2011 and net cash provided of $767 million for 2010. The cash flow from investing activities is impacted 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. Net cash provided by investing activities in 2010 primarily related to the sale of short term investments which was used to fund the $1.9 billion initial net cash settlement with NICO as discussed above.

Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, outflows for stockholder dividends or repayment of debt and outlays to reacquire equity instruments. Net cash used by financing activities was $239 million, $644 million, and $742 million for 2012, 2011 and 2010.

Liquidity

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

During 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 dividends of $450 million.

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

49

Common Stock Dividends

Dividends of $0.60 per share of our common stock were declared and paid in 2012. On February 8, 2013, our Board of Directors declared a quarterly dividend of $0.20 per share, payable March 7, 2013 to stockholders of record on February 21, 2013. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs, and regulatory constraints.

Our ability to pay dividends and other credit obligations is significantly dependent on receipt of dividends from our subsidiaries. The payment of dividends to us by our insurance subsidiaries without prior approval of the insurance department of each subsidiary's domiciliary jurisdiction is limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective state insurance departments.

Further information on our dividends from subsidiaries is provided in Note M to the Consolidated Financial Statements included under Item 8.

Commitments, Contingencies, and Guarantees

We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

A summary of our commitments as of December 31, 2012 is presented in the following table.

Contractual Commitments

Future policy benefit reserves of $697 million and policyholders' fund reserves of $35 million related to business which has been 100% ceded to unaffiliated parties in connection with the sale of our individual life business in 2004 are not included. See the Reserves - Estimates and Uncertainties section of this MD&A for further information.

(d) Primarily relating to outsourced services and software.

(e) Does not include expected estimated contribution of $96 million to our pension and postretirement plans in 2013.

Further information on our commitments, contingencies and guarantees is provided in Notes A, C, D, G, H, J, K and L to the Consolidated Financial Statements included under Item 8.

Ratings

Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries are rated by major rating agencies, and these ratings reflect the rating agency's opinion of the insurance company's financial strength, operating performance, strategic position and ability to meet our obligations to policyholders. Agency ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization. Each agency's rating should be evaluated independently of any other agency's rating. One or more of these agencies could take action in the future to change the ratings of our insurance subsidiaries.

The table below reflects the various group ratings issued by A.M. Best, Moody's and S&P for the property and casualty and life companies. The table also includes the ratings for CNAF senior debt.

	Insurance Financial Strength Ratings			Corporate Debt Ratings
	Property & Casualty		Life	CNAF
	CCC Group	Western Surety Group	CAC	Senior Debt
A.M. Best	A	A	A-	bbb
Moody's	A3	Not rated	Not rated	Baa2
S&P	A-	A-	Not rated	BBB-

S&P maintains a positive outlook and A.M. Best maintains a stable outlook on the Company. In June 2012, Moody's upgraded the Company's debt rating to Baa2 with a stable outlook, affirmed our insurance financial strength rating and revised its outlook on our financial strength rating to positive from stable.

If our property and casualty insurance financial strength ratings were downgraded below current levels, our business and results of operations could be materially adversely affected. The severity of the impact on our business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of our insurance products to certain markets and the required collateralization of certain future payment obligations or reserves. Downgrades of our corporate debt ratings could result in adverse effects upon our liquidity position, including negatively impacting our ability to access capital markets, and increasing our financing costs.

Further, additional collateralization may be required for certain settlement agreements and assumed reinsurance contracts, as well as derivative contracts, if our ratings or other specific criteria fall below certain thresholds.

In addition, it is possible that a lowering of the corporate debt ratings of Loews by certain of these agencies could result in an adverse impact on our ratings, independent of any change in our circumstances. None of the major rating agencies which rates Loews currently maintains a negative outlook or has Loews on negative Credit Watch.

ACCOUNTING STANDARDS UPDATES

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 this Report, 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.

52

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 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our financial instruments are exposed to various market risks, such as interest rate risk, equity price risk and foreign currency risk. Due to the level of risk associated with certain invested assets and the level of uncertainty related to changes in the value of these assets, it is possible that changes in these risks in the near term could have a material adverse impact on our results of operations or equity.

Discussions herein regarding market risk focus on only one element of market risk, which is price risk. Price risk relates to changes in the level of prices due to changes in interest rates, equity prices, foreign exchange rates or other factors such as credit spreads and market liquidity. The fair value of the financial instruments is generally adversely affected when interest rates rise, equity markets decline and the dollar strengthens against foreign currency.

Active management of market risk is integral to our operations. We may take the following actions to manage our exposure to market risk within defined tolerance ranges: (1) change the character of future investments purchased or sold, (2) use derivatives to offset the market behavior of existing assets and liabilities or assets expected to be purchased and liabilities to be incurred, or (3) rebalance our existing asset and liability portfolios.

Sensitivity Analysis

We monitor our sensitivity to interest rate changes by revaluing financial assets and liabilities using a variety of different interest rates. The Company uses duration and convexity at the security level to estimate the change in fair value that would result from a change in each security's yield. Duration measures the price sensitivity of an asset to changes in the yield rate. Convexity measures how the duration of the asset changes with interest rates. The duration and convexity analysis takes into account the unique characteristics (e.g., call and put options and prepayment expectations) of each security in determining the hypothetical change in fair value. The analysis is performed at the security level and aggregated up to the asset category levels for reporting in the tables below.

The evaluation is performed by applying an instantaneous change in yield rates of varying magnitudes on a static balance sheet to determine the effect such a change in rates would have on our fair value at risk and the resulting effect on stockholders' equity. The analysis presents the sensitivity of the fair value of our financial instruments to selected changes in market rates and prices. The range of change chosen reflects our view of changes that are reasonably possible over a one-year period. The selection of the range of values chosen to represent changes in interest rates should not be construed as our prediction of future market events, but rather an illustration of the impact of such events.

The sensitivity analysis estimates the decline in the fair value of our interest sensitive assets and liabilities that were held on December 31, 2012 and 2011 due to an instantaneous change in the yield of the security at the end of the period of 100 and 150 basis points.

The sensitivity analysis also assumes an instantaneous 10% and 20% decline in the foreign currency exchange rates versus the United States dollar from their levels at December 31, 2012 and 2011, with all other variables held constant.

Equity price risk was measured assuming an instantaneous 10% and 25% decline in the S&P 500 from its level at December 31, 2012 and 2011, with all other variables held constant. Our equity holdings were assumed to be highly and positively correlated with the S&P 500.

The value of limited partnerships can be affected by changes in equity markets as well as changes in interest rates. A model was developed to analyze the observed changes in the value of limited partnerships held by the Company over a multiple year period along with the corresponding changes in various equity indices and interest rates. The result of the model allowed us to estimate the change in value of limited partnerships when equity markets decline by 10% and 25% and interest rates increase by 100 and 150 basis points.

54

Our sensitivity analysis has also been applied to the assets supporting our separate account business because certain of our separate account products guarantee principal and a minimum rate of interest. All or a portion of these decreases related to the separate account assets may be offset by decreases in related separate account liabilities to customers, but that is dependent on the position of the separate account in relation to the specific guarantees at the time of the interest rate or price decline. Similarly, increases in the fair value of the separate account investments would also be offset by increases in the same related separate account liabilities by the same approximate amounts.

The following tables present the estimated effects on the fair value of our financial instruments at December 31, 2012 and 2011, due to an increase in yield rates of 100 basis points, a 10% decline in foreign currency exchange rates and a 10% decline in the S&P 500.

Notes to Consolidated Financial Statements

Note A. Summary of Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of December 31, 2012.

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. The preparation of 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 Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The Company has historically reported certain run-off insurance operations acquired in its merger with The Continental Corporation in 1995 as discontinued operations. Due to the immateriality of the remaining liabilities, effective in the third quarter of 2011, the Company is no longer reporting these run-off operations as discontinued operations.

Business

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

The Company serves a wide variety of customers, including small, medium and large businesses; insurance companies; associations; professionals; groups; and individuals with a broad range of insurance and risk management products and services.

Core insurance products include commercial property and casualty coverages, including surety. Non-core insurance products, which primarily have been placed in run-off, include life and accident and health insurance and retirement products and annuities. CNA services include risk management, information services, warranty and claims administration. The Company's products and services are primarily marketed through independent agents, brokers, and managing general underwriters.

Noncontrolling Interests

Net income attributable to noncontrolling interests for the years ended December 31, 2011 and 2010 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.

Insurance Operations

Premiums: Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured which principally are earned ratably over the duration of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.

67

Insurance receivables include balances due currently or in the future, including amounts due from insureds related to losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. Amounts are considered past due based on policy payment terms. That allowance is determined based on periodic evaluations of aged receivables, management's experience and current economic conditions. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached.

Property and casualty contracts that are retrospectively rated contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions and loss experience of the insured during the experience period. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the experience period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company adjusts such estimated ultimate premium amounts during the course of the experience period based on actual results to date. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.

Claim and claim adjustment expense reserves: Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (A&EP), workers' compensation lifetime claims, and accident and health claims, are not discounted and are based on 1) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; 2) estimates of incurred but not reported (IBNR) losses; 3) estimates of losses on assumed reinsurance; 4) estimates of future expenses to be incurred in the settlement of claims; 5) estimates of salvage and subrogation recoveries and 6) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets.

Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $1.3 billion and $1.4 billion as of December 31, 2012 and 2011. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on the Consolidated Balance Sheets.

Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. Certain structured settlements are funded by annuities purchased from Continental Assurance Company (CAC) for which the related annuity obligations are reported in Future policy benefits reserves. Obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and carried at present values determined using interest rates ranging from 7.1% to 9.7% at December 31, 2012 and 5.5% to 8.0% at December 31, 2011. At December 31, 2012 and 2011, the discounted reserves for unfunded structured settlements were $602 million and $632 million, net of discount of $1.0 billion and $1.1 billion.

Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. Accident and health claim reserves are calculated using mortality and morbidity assumptions based on Company and industry experience. Workers' compensation lifetime claim reserves and accident and health claim reserves are discounted at interest rates ranging from 3.0% to 6.5% at both December 31, 2012 and 2011. At December 31, 2012 and 2011, such discounted reserves totaled $2.2 billion and $2.1 billion, net of discount of $837 million and $520 million.

Future policy benefits reserves: Reserves for long term care products and payout annuity contracts are computed using the net level premium method, which incorporates actuarial assumptions as to morbidity, mortality, persistency, discount rates, which are impacted by expected investment yields, and expenses. Expense assumptions include the estimated effects of expenses to be incurred beyond the premium paying period. Actuarial assumptions generally vary by plan, age at issue and policy duration. The initial assumptions are determined at issuance, include a margin for adverse deviation, and are locked in throughout the life of the contract unless a premium deficiency develops. If a premium deficiency emerges, the assumptions are unlocked and deferred acquisition costs, if any, and the future policy benefit reserves are adjusted. Interest rates for long-term care products range from 5.0% to

68

7.4% at December 31, 2012 and from 5.0% to 7.5% at December 31, 2011. Interest rates for payout annuity contracts range from 5.0% to 8.7% at December 31, 2012 and from 5.4% to 7.5% at December 31, 2011. In 2012, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in discount rates, which reflect the current low interest rate environment and our view of expected investment yields, resulting in loss recognition which increased insurance liabilities by $33 million. In 2011, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in mortality and discount rates, resulting in loss recognition which increased insurance reserves by $166 million.

Policyholders' funds reserves: Policyholders' funds reserves primarily include reserves for investment contracts without life contingencies. For these contracts, policyholder liabilities are generally equal to the accumulated policy account values, which consist of an accumulation of deposit payments plus credited interest, less withdrawals and amounts assessed through the end of the period.

Guaranty fund and other insurance-related assessments: Liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated, and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for guaranty funds and other insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2012 and 2011, the liability balances were $143 million and $152 million. As of December 31, 2012 and 2011, included in Other assets on the Consolidated Balance Sheets were $2 million of related assets for premium tax offsets. This asset is limited to the amount that is able to be offset against premium tax on future premium collections from business written or committed to be written.

Reinsurance: Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.

Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. Reinsurance receivables are reported net of an allowance for uncollectible amounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of the Company.

The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The allowance for uncollectible reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, management's experience and current economic conditions. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if the Company becomes aware of significant changes related to a reinsurer. Because billed receivables are generally 5% or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for uncollectible reinsurance receivables are presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables related to paid losses from insolvent insurers are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Reinsurance contracts that do not effectively transfer the economic risk of loss on the underlying policies are recorded using the deposit method of accounting, which requires that premium paid or received by the ceding company or assuming company be accounted for as a deposit asset or liability. The Company had $3 million and $18 million recorded as deposit assets at December 31, 2012 and 2011, and $125 million and $123 million recorded as deposit liabilities at December 31, 2012 and 2011. Income on reinsurance contracts accounted for under the

69

deposit method is recognized using an effective yield based on the anticipated timing of payments and the remaining life of the contract. When the anticipated timing of payments changes, the effective yield is recalculated to reflect actual payments to date and the estimated timing of future payments. The deposit asset or liability is adjusted to the amount that would have existed had the new effective yield been applied since the inception of the contract.

Participating insurance: Policyholder dividends are accrued using an estimate of the amount to be paid based on underlying contractual obligations under policies and applicable state laws. Limitations exist on the amount of income from participating life insurance contracts that may be distributed to stockholders, and therefore the share of income on these policies that cannot be distributed to stockholders is excluded from Stockholders' equity by a charge to operations and other comprehensive income and the establishment of a corresponding liability.

Deferred acquisition costs: Acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Deferred acquisition costs related to long term care contracts issued prior to January 1, 2004 include costs which vary with and are primarily related to the acquisition of business, as further discussed at the Accounting Standards Update section of this note.

Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned.

Deferred acquisition costs related to long term care contracts are 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. Assumptions are made at the date of policy issuance or acquisition and are consistently applied during the lives of the contracts. Deviations from estimated experience are included in results of operations when they occur. For these contracts, the amortization period is typically the estimated life of the policy. At December 31, 2012 and 2011, Deferred acquisition costs were presented net of Shadow Adjustments, as defined later in this note, of $369 million and $398 million.

The Company evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current results of operations.

Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs. Unamortized deferred acquisition costs relating to contracts that have been substantially changed by a modification in benefits, features, rights or coverages that were not anticipated in the original contract are not deferred and are included as a charge to operations in the period during which the contract modification occurred.

Investments in life settlement contracts and related revenue recognition: Prior to 2002, the Company purchased investments in life settlement contracts. A life settlement contract is a contract between the owner of a life insurance policy (the policy owner) and a third-party investor (investor). Under a life settlement contract, the Company obtains the ownership and beneficiary rights of an underlying life insurance policy.

The Company accounts for its investments in life settlement contracts using the fair value method. Under the fair value method, each life settlement contract is carried at its fair value at the end of each reporting period. The change in fair value, life insurance proceeds received and periodic maintenance costs, such as premiums, necessary to keep the underlying policy in force, are recorded in Other revenues on the Consolidated Statements of Operations. The fair value of the Company's investments in life settlement contracts were $100 million and $117 million at December 31, 2012 and 2011, and are included in Other assets on the Consolidated Balance Sheets. The cash receipts and payments related to life settlement contracts are included in Cash flows from operating activities on the Consolidated Statements of Cash Flows.

70

The following table details the values for life settlement contracts. The determination of fair value is discussed in Note E.

December 31, 2012	Number of Life Settlement Contracts	Fair Value of Life Settlement Contracts (In millions)		Face Amount of Life Insurance Policies (In millions)
Estimated maturity during:
2013	70	$	15	$	41
2014	60	13		36
2015	60	11		34
2016	50	9		30
2017	40	7		27
Thereafter	390	45		237
Total	670	$	100	$	405

The Company uses an actuarial model to estimate the aggregate face amount of life insurance that is expected to mature in each future year and the corresponding fair value. This model projects the likelihood of the insured's death for each inforce policy based upon the Company's estimated mortality rates, which may vary due to the relatively small size of the portfolio of life settlement contracts. The number of life settlement contracts presented in the table above is based upon the average face amount of inforce policies estimated to mature in each future year.

The increase in fair value recognized for the years ended December 31, 2012, 2011 and 2010 on contracts still being held was $11 million, $5 million and $10 million. The gains recognized during the years ended December 31, 2012, 2011 and 2010 on contracts that settled were $42 million, $28 million and $19 million.

Separate Account Business: Separate account assets and liabilities represent contract holder funds related to investment and annuity products for which the policyholder assumes substantially all the risk and reward. The assets are segregated into accounts with specific underlying investment objectives and are legally segregated from the Company. All assets of the separate account business are carried at fair value with an equal amount recorded for separate account liabilities. Fee income accruing to the Company related to separate accounts is primarily included within Other revenues on the Consolidated Statements of Operations.

A number of separate account pension deposit contracts guarantee principal and an annual minimum rate of interest. If aggregate contract value in the separate account exceeds the fair value of the related assets, an additional Policyholders' funds liability is established. During 2012 and 2010, the Company decreased this pretax Policyholders' funds liability by $20 million and $24 million. The Company increased this pretax Policyholders' funds liability by $18 million in 2011. Certain of these contracts are subject to a fair value adjustment if terminated by the policyholder.

Investments

The Company classifies its fixed maturity securities and its equity securities as either available-for-sale or trading, and as such, they are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Operations. Changes in fair value related to available-for-sale securities are reported as a component of Other comprehensive income. The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity, which are included in Net investment income on the Consolidated Statements of Operations. Losses may be recognized within Net realized investment gains (losses) on the Consolidated Statements of Operations when a decline in value is determined by the Company to be other-than-temporary.

To the extent that unrealized gains on fixed income securities supporting long term care products and payout annuity contracts would result in a premium deficiency if those gains were realized, a related decrease in Deferred acquisition costs and/or increase in Insurance reserves are recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (Shadow Adjustments). For the years ended December 31, 2012 and 2011, Shadow Adjustments, net of participating policyholders' interest, of $789 million and $572 million, were recorded, net of

71

tax. At December 31, 2012 and 2011, net unrealized gains on investments included in Accumulated other comprehensive income (AOCI) were correspondingly reduced by $1,511 million and $722 million.

For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The amortized cost of high credit quality securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reflected in Net investment income on the Consolidated Statements of Operations. Interest income on lower rated securities is determined using the prospective yield method.

The Company's carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the General Partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. Changes in net asset values are accounted for under the equity method and recorded within Net investment income on the Consolidated Statements of Operations.

Mortgage loans are commercial in nature, are carried at unpaid principal balance, net of unamortized fees and any valuation allowance, and are recorded once funded. Mortgage loans are considered to be impaired loans when it is probable that contractual principal and interest payments will not be collected. A valuation allowance is established for impaired loans to the extent that the present value of expected future cash flows discounted at the loan's original effective interest rate is less than the carrying value of the loan. Interest income from mortgage loans is recognized on an accrual basis using the effective yield method. Accrual of income is generally suspended for mortgage loans that are impaired and collection of principal and interest payments is unlikely. Mortgage loans are considered past due when full principal or interest payments have not been received according to contractual terms.

Other invested assets are carried at fair value and include overseas deposits, certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected. Overseas deposits are primarily short-term government securities, agency securities, and corporate bonds held in trusts that are managed by Lloyd's of London (Lloyd's). These funds are required of Lloyd's syndicates to protect policyholders in overseas markets and may be denominated in local currency. Changes in fair value of overseas deposits are reflected in Net investment income on the Consolidated Statements of Operations. Changes in fair value of certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected are reported in Net realized investment gains (losses) in the Consolidated Statements of Operations.

Short term investments are carried at fair value, with the exception of cash accounts earning interest, which are carried at cost and approximate fair value. Changes in fair value are reported as a component of Other comprehensive income.

Purchases and sales of all securities are recorded on the trade date, except for private placement debt securities, including bank loan participations, which are recorded once funded. Realized investment gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.

Income Taxes

The Company and its eligible subsidiaries (CNA Tax Group) are included in the consolidated federal income tax return of Loews and its eligible subsidiaries. The Company accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized.

72

Pension and Postretirement Benefits

The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities on the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits and actuarial gains and losses are recognized in the year in which the changes occur through Other comprehensive income. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits, and amortization of actuarial gains and losses are recognized on the Consolidated Statements of Operations.

Stock-Based Compensation

The Company records compensation expense using the fair value method for all awards it grants, modifies, repurchases or cancels primarily on a straight-line basis over the requisite service period, generally four years.

Foreign Currency

Foreign currency translation gains and losses are reflected in Stockholders' equity as a component of Accumulated other comprehensive income. The Company's foreign subsidiaries' balance sheet accounts are translated at the exchange rates in effect at each year end and income statement accounts are either translated at the exchange rate on the date of the transaction or at the average exchange rates. Foreign currency transaction gains (losses) of $12 million, $4 million and $(19) million were included in determining net income (loss) for the years ended December 31, 2012, 2011 and 2010.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is determined principally on the straight-line method. Furniture and fixtures are depreciated over seven years. Office equipment is depreciated over five years. The estimated lives for data processing equipment and software range from three to five years. Leasehold improvements are depreciated over the corresponding lease terms not to exceed the underlying asset life. The Company's owned buildings, and related capital improvements, are depreciated over periods not to exceed fifty years.

Goodwill

Goodwill represents the excess of purchase price over the fair value of the net assets of acquired entities and businesses. Goodwill related to Hardy may change from period to period as a result of foreign currency translation. Goodwill is tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the goodwill recognized as part of the acquisition of Hardy.

Intangible Assets

Intangible assets are reported within Other assets. As of December 31, 2012, the Company's finite-lived intangible assets were $40 million. The Company had no finite-lived intangible assets at December 31, 2011. Finite-lived intangible assets are amortized over their estimated useful lives. As of December 31, 2012, and 2011, the Company's indefinite-lived intangible assets were $73 million and $16 million. Indefinite-lived intangible assets are tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the intangible assets acquired as part of the acquisition of Hardy.

Earnings (Loss) Per Share Data

Earnings (loss) per share attributable to the Company's common stockholders is based on 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.

73

For the years ended December 31, 2012, 2011, and 2010, approximately 417 thousand, 290 thousand and 380 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 730 thousand, 1.1 million and 1.2 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.

Supplementary Cash Flow Information

Cash payments made for interest were $170 million, $175 million and $145 million for the years ended December 31, 2012, 2011 and 2010. Cash refunds received for income taxes were $29 million and $175 million for the years ended December 31, 2012 and 2010. Cash payments made for income taxes were $61 million for the year ended December 31, 2011.

Accounting Standards Updates

Adopted

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 year ended December 31, 2012, the adoption of the new accounting guidance resulted in a $5 million decrease in Net income attributable to CNA and a $0.02 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 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 and the Company's acquisition of the noncontrolling interest of Surety as discussed above.

The impacts on the Company's Consolidated Statements of Operations for the years ended December 31, 2011 and 2010 were a $2 million increase and no impact in Other net realized investment gains, a $234 million and $219 million decrease in Amortization of deferred acquisition costs, a $242 million and $219 million increase in Other operating expenses, a $4 million and $1 million decrease in Income tax expense, resulting in a $2 million decrease and a $1 million increase in Net income attributable to CNA, and a $0.01 decrease and no impact 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.

74

Note B. Hardy

On July 2, 2012, the Company completed the acquisition of all outstanding shares of Hardy, a specialized 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 December 31, 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 year ended December 31, 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:

Net OTTI losses recognized in earnings	$	154	$	216	$	232

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.

78

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.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the December 31, 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 December 31, 2012.

The following table summarizes the activity for the years ended December 31, 2012, 2011 and 2010 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at December 31, 2012, 2011 and 2010 for which a portion of an OTTI loss was recognized in Other comprehensive income.

Contractual Maturity

The following table summarizes available-for-sale fixed maturity securities by contractual maturity at December 31, 2012 and 2011. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid with or without call or prepayment penalties. Securities not due at a single date are allocated based on weighted average life.

Limited Partnerships

The carrying value of limited partnerships as of December 31, 2012 and 2011 was $2,462 million and $2,245 million, which includes undistributed earnings of $768 million and $560 million. Limited partnerships comprising 67% of the total carrying value are reported on a current basis through December 31, 2012 with no reporting lag, 17% are reported on a one month lag and the remainder are reported on more than a one month lag. As of December 31, 2012 and 2011, the Company had 79 active limited partnership investments. The number of limited partnerships held and the strategies employed provide diversification to the limited partnership portfolio and the overall invested asset portfolio.

Of the limited partnerships held, 80% and 81% at December 31, 2012 and 2011 employ hedge fund strategies that generate returns through investing in securities that are marketable while engaging in various management techniques primarily in public fixed income and equity markets. These hedge fund strategies include both long

82

and short positions in fixed income, equity and derivative instruments. The hedge fund strategies may seek to generate gains from mispriced or undervalued securities, price differentials between securities, distressed investments, sector rotation, or various arbitrage disciplines. Within hedge fund strategies, approximately 48% were equity related, 27% pursued a multi-strategy approach, 22% were focused on distressed investments and 3% were fixed income related at December 31, 2012.

Limited partnerships representing 16% and 14% at December 31, 2012 and 2011 were invested in private debt and equity. The remaining were invested in various other partnerships including real estate. The ten largest limited partnership positions held totaled $1,309 million and $1,218 million as of December 31, 2012 and 2011. Based on the most recent information available regarding the Company’s percentage ownership of the individual limited partnerships, the carrying value reflected on the Consolidated Balance Sheets represents approximately 4% of the aggregate partnership equity at December 31, 2012 and 2011, and the related income reflected on the Consolidated Statements of Operations represents approximately 3%, 4%, and 3% of the changes in partnership equity for all limited partnership investments for the years ended December 31, 2012, 2011 and 2010.

While the Company generally does not invest in highly leveraged partnerships, there are risks which may result in losses due to short-selling, derivatives or other speculative investment practices. The use of leverage increases volatility generated by the underlying investment strategies.

The Company’s limited partnership investments contain withdrawal provisions that generally limit liquidity for a period of thirty days up to one year and in some cases do not permit withdrawals until the termination of the partnership. Typically, withdrawals require advance written notice of up to 90 days.

Commercial Mortgage Loans

Risks related to the recoverability of loan balances include declines in the estimated cash flows from underlying property leases, fair value of collateral and creditworthiness of tenants of credit tenant loan properties, where lease payments directly service the loan. The Company evaluates loans for impairment on a specific loan basis and identifies loans for evaluation of impairment based on the collection experience of each loan and other credit quality indicators such as debt service coverage ratio and the creditworthiness of the borrower or tenants of credit tenant loan properties. As of December 31, 2012 and 2011, there were no loans past due or in non-accrual status, and no valuation allowance was recorded.

Investment Commitments

As of December 31, 2012, the Company had committed approximately $202 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships.

As of December 31, 2012, the Company had mortgage loan commitments of $22 million representing signed loan applications received and accepted.

The Company invests in various privately placed debt securities, including bank loans, as part of its overall investment strategy and has committed to additional future purchases, sales and funding. As of December 31, 2012, the Company had commitments to purchase $185 million and sell $164 million of such investments.

Investments on Deposit

Securities with carrying values of approximately $3.6 billion and $3.5 billion were deposited by the Company’s insurance subsidiaries under requirements of regulatory authorities and others as of December 31, 2012 and 2011.

Cash and securities with carrying values of approximately $4 million and $5 million were deposited with financial institutions as collateral for letters of credit as of December 31, 2012 and 2011. In addition, cash and securities were deposited in trusts with financial institutions to secure reinsurance and other obligations with various third parties. The carrying values of these deposits were approximately $277 million and $288 million as of December 31, 2012 and 2011.

Note D. Derivative Financial Instruments

The Company may use derivatives in the normal course of business, primarily in an attempt to reduce its exposure to market risk (principally interest rate risk, credit risk, equity price risk and foreign currency risk) stemming from various assets and liabilities. The Company's principal objective under such strategies is to achieve the desired reduction in economic risk, even if the position does not receive hedge accounting treatment.

The Company may enter into interest rate swaps, futures and commitments to purchase securities to manage interest rate risk. Credit derivatives such as credit default swaps (CDS) are entered into to modify the credit risk inherent in certain investments. The Company may use foreign currency forward contracts to manage foreign currency risk.

In addition to the derivatives used for risk management purposes described above, the Company may also use derivatives for purposes of income enhancement. Income enhancement transactions are entered into with the intention of providing additional income or yield to a particular portfolio segment or instrument. Income enhancement transactions are limited in scope and primarily involve the sale of covered options in which the Company receives a premium in exchange for selling a call or put option.

Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to the instruments recognized on the Consolidated Balance Sheets. The Company generally requires that all over-the-counter derivative contracts be governed by an International Swaps and Derivatives Association Master Agreement, and exchanges collateral under the terms of these agreements with its derivative investment counterparties depending on the amount of the exposure and the credit rating of the counterparty. The Company does not offset its net derivative positions against the fair value of the collateral provided. The fair value of cash collateral provided by the Company was $1 million at December 31, 2012 and 2011. There was no cash collateral received from counterparties held at December 31, 2012 or 2011.

Derivative securities are recorded at fair value. See Note E for information regarding the fair value of derivative securities. Changes in the fair value of derivatives not associated with the trading portfolio are reported in Net realized investment gains (losses) on the Consolidated Statements of Operations. Changes in the fair value of derivatives associated with the trading portfolio are reported in Net investment income on the Consolidated Statements of Operations.

During the year ended December 31, 2012, new derivative transactions entered into totaled $1,581 million in notional value while derivative termination activity totaled $1,543 million. This activity was primarily attributable to interest rate futures, forward commitments for mortgage-backed securities, and foreign currency forwards. During the year ended December 31, 2011, new derivative transactions entered into totaled $1,073 million in notional value while derivative termination activity totaled $1,076 million. This activity was primarily attributable to interest rate futures, forward commitments for mortgage-backed securities, and foreign currency forwards.

Note E. Fair Value

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

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

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

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

Prices may fall within Level 1, 2 or 3 depending upon the methodologies and inputs used to estimate fair value for each specific security. Prices are determined by a dedicated group who ultimately report to the Company's 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 and $72 million of transfers from Level 1 to Level 2during the year ended December 31, 2012. There were no significant transfers between Level 1 and Level 2 during the year ended December 31, 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 and the credit spread adjustment that is security specific. Fair value of certain private placement debt securities is determined using internal models with inputs that are not market observable.

Equity Securities

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

91

Other Invested Assets

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities include overseas deposits, which can be redeemed at net asset value in 90 days or less, and derivatives, primarily currency forwards valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, credit default swaps, equity warrants and options, are valued using inputs including broker/dealer quotes and are classified within Level 3 of the valuation hierarchy due to a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include 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 Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.

Life Settlement Contracts

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

Separate Account Business

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

Significant Unobservable Inputs

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

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

For fixed maturity securities, an increase to the expected call date assumption and credit spread adjustment 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 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 Consolidated Balance Sheets are listed in the tables below.

December 31, 2012	Carrying Amount		Estimated Fair Value

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

Note F. Income Taxes

The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. Loews and the Company have agreed that for each taxable year, the Company will 1) be paid by Loews the amount, if any, by which the Loews consolidated federal income tax liability is reduced by virtue of the inclusion of the CNA Tax Group in the Loews consolidated federal income tax return, or 2) pay to Loews an amount, if any, equal to the federal income tax that would have been payable by the CNA Tax Group filing a separate consolidated tax return. In the event that Loews should have a net operating loss in the future computed on the basis of filing a separate consolidated tax return without the CNA Tax Group, the Company may be required to repay tax recoveries previously received from Loews. This agreement may be canceled by either party upon 30 days written notice.

For the years ended December 31, 2012, 2011, and 2010 the Company received from Loews $75 million, $10 million, and $298 million related to federal income taxes.

For 2010 through 2012, the IRS has accepted Loews and the Company into the Compliance Assurance Process (CAP), which is a voluntary program for large corporations. Under CAP, the IRS conducts a real-time audit and works contemporaneously with the Company to resolve any issues prior to the filing of the tax return. The Company believes that this approach should reduce tax-related uncertainties, if any.

At December 31, 2012 and 2011, there were no unrecognized tax benefits.

The Company recognizes interest accrued related to: 1) unrecognized tax benefits in Interest expense and 2) tax refund claims in Other revenues on the Consolidated Statements of Operations. The Company recognizes penalties (if any) in Income tax (expense) benefit on the Consolidated Statements of Operations. During 2012, the Company recognized $2 million of interest income and no penalties. During 2011 and 2010, the Company did not recognize any interest or penalties. There were no amounts accrued for interest or penalties at December 31, 2012 or 2011.

The following table provides a reconciliation between the Company's federal income tax (expense) benefit at statutory rates and the recorded income tax (expense) benefit, excluding discontinued operations.

Net unrealized gains	737		513
Other liabilities	57		37
Gross deferred tax liabilities	1,070		791
Net deferred tax asset	$	93	$	415

At December 31, 2012, the CNA Tax Group had loss carryforwards of approximately $9 million which expire in 2014, and tax credit carryforwards of $4 million.

Although realization of deferred tax assets is not assured, management believes it is more likely than not that the recognized net deferred tax asset will be realized through recoupment of ordinary and capital taxes paid in prior carryback years and through future earnings, reversal of existing temporary differences and available tax planning strategies. As a result, no valuation allowance was recorded at December 31, 2012 or 2011.

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 $391 million, $222 million and $121 million for the years ended December 31, 2012, 2011 and 2010. Catastrophe losses in 2012 related primarily to Storm Sandy and other U.S. storms.

A&EP Reserves

On August 31, 2010, Continental Casualty Company (CCC) together with several of the Company’s insurance subsidiaries completed a transaction with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which substantially all of the Company’s legacy A&EP liabilities were ceded to NICO (Loss Portfolio Transfer).

Under the terms of the NICO transaction, effective January 1, 2010 the Company ceded approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $4 billion. Included in the $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves was approximately $90 million of net claim and allocated claim adjustment expense reserves relating to the Company’s discontinued operations. The $1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third party reinsurance contracts. The NICO aggregate reinsurance limit also covers credit risk on the existing third party reinsurance related to these liabilities.

The Company paid NICO a reinsurance premium of $2 billion and transferred to NICO billed third party reinsurance receivables related to A&EP claims with a net book value of $215 million (net of an allowance of $100 million for uncollectible reinsurance receivables on billed third party reinsurance receivables, as discussed further below). As of August 31, 2010, NICO deposited approximately $2.2 billion in a collateral trust account as security for its obligations to the Company. NICO may reduce the collateral by the amount of net A&EP claim and allocated claim adjustment expense payments. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the full aggregate reinsurance limit as well as certain of NICO’s performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third party reinsurers related to the Company’s A&EP claims.

The following table displays the impact of the Loss Portfolio Transfer on the 2010 Consolidated Statement of Operations.

Impact on Consolidated Statement of Operations

Year ended December 31
(In millions)	2010
Other operating expenses	$	529
Income tax benefit	185
Loss from continuing operations, included in the Corporate & Other Non-Core segment	(344		)
Loss from discontinued operations	(21		)
Net loss attributable to CNA	$	(365	)

In connection with the transfer of billed third party reinsurance receivables related to A&EP claims and the coverage of credit risk afforded under the terms of the Loss Portfolio Transfer, the Company reduced its allowance for uncollectible reinsurance receivables on billed third party reinsurance receivables and ceded claim and allocated claim adjustment expense reserves by $200 million. This reduction is reflected in Other operating expenses presented above.

The Loss Portfolio Transfer is considered a retroactive reinsurance contract. In the event that the cumulative claim and allocated claim adjustment expenses ceded under the Loss Portfolio Transfer exceed the consideration paid, the resulting gain from such excess would be deferred. A cumulative amortization adjustment would be recognized in earnings in the period such excess arises so that the resulting deferred gain would reflect the balance that would have existed if the revised estimate was available at the inception date of the Loss Portfolio Transfer. This accounting generally results in a reserve charge because of the timing difference between the recognition of the gross adverse reserve development and the related ceded reinsurance benefit. However, there is no economic impact as long as the additional losses are within the limit under the contract.

The remaining amount available under the $4 billion aggregate limit of the Loss Portfolio Transfer was $2.0 billion on an incurred basis at December 31, 2012. This incurred amount includes $399 million of adverse prior year development since the contract effective date of January 1, 2010. Any future adverse prior year development in excess of approximately $230 million would put the Loss Portfolio Transfer into an overall gain position under retroactive reinsurance accounting. The net ultimate paid losses ceded under the Loss Portfolio Transfer were $661 million through December 31, 2012. The fair value of the collateral trust account at December 31, 2012 was $2.5 billion.

Net Prior Year Development

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. These changes can be favorable or unfavorable. The following tables and discussion include the net prior year development recorded for CNA Specialty, CNA Commercial, Hardy and Corporate & Other Non-Core segments for the years ended December 31, 2012, 2011 and 2010. The net prior year development presented below includes premium development due to its direct relationship to claim and claim adjustment expense reserve development. The net prior year development presented below also includes the impact of commutations and write-offs, but excludes the impact of increases or decreases in the allowance for uncollectible reinsurance. See Note I for further discussion of the provision for uncollectible reinsurance.

Favorable net prior year development of $11 million, $29 million and $2 million was recorded in the Life & Group Non-Core segment for the years ended December 31, 2012, 2011 and 2010.

For the year ended December 31, 2012, favorable premium development was recorded for CNA Commercial primarily due to premium adjustments on auditable policies arising from increased exposures.

For the year ended December 31, 2011, favorable premium development was recorded for CNA Specialty primarily due to changes in estimates of exposures in medical professional liability tail coverages. 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.

For the year ended December 31, 2010, unfavorable premium development for CNA Commercial was recorded due to a change in ultimate premium estimates relating to retrospectively rated policies and return premium on auditable policies due to reduced exposures.

Note H. Legal Proceedings and Contingent Liabilities

The Company is a party to routine litigation incidental to its business, which, based on the facts and circumstances currently known, is not material to the Consolidated Financial Statements.

Note I. Reinsurance

The Company cedes insurance to reinsurers to limit its maximum loss, provide greater diversification of risk, minimize exposures on larger risks and to exit certain lines of business. The ceding of insurance does not discharge the primary liability of the Company. A credit exposure exists with respect to property and casualty and life reinsurance ceded to the extent that any reinsurer is unable to meet its obligations or to the extent that the reinsurer disputes the liabilities assumed under reinsurance agreements. Property and casualty reinsurance coverages are tailored to the specific risk characteristics of each product line and the Company's retained amount varies by type of coverage. Reinsurance contracts are purchased to protect specific lines of business such as property and workers' compensation. Corporate catastrophe reinsurance is also purchased for property and workers' compensation exposure. Currently, most reinsurance contracts are purchased on an excess of loss basis. The Company also utilizes facultative reinsurance in certain lines. In addition, the Company assumes reinsurance, primarily through Hardy and as a member of various reinsurance pools and associations.

The following table summarizes the amounts receivable from reinsurers at December 31, 2012 and 2011.

Components of Reinsurance Receivables

December 31

Ceded policyholders' funds	35			36
Reinsurance receivables related to paid losses	311			244
Reinsurance receivables	6,231			6,092
Allowance for uncollectible reinsurance	(73		)	(91		)
Reinsurance receivables, net of allowance for uncollectible reinsurance	$	6,158		$	6,001

The Company has established an allowance for uncollectible reinsurance receivables. The Company reviews the allowance quarterly and adjusts the allowance as necessary to reflect changes in estimates of uncollected balances. The allowance may also be reduced related to write-offs of reinsurance receivable balances.

The Company attempts to mitigate its credit risk related to reinsurance by entering into reinsurance arrangements with reinsurers that have credit ratings above certain levels, and by obtaining collateral. On a limited basis, the Company may enter into reinsurance agreements with reinsurers that are not rated, primarily captive reinsurers. The primary methods of obtaining collateral are through reinsurance trusts, letters of credit and funds withheld balances. Such collateral was approximately $3.7 billion and $3.6 billion at December 31, 2012 and 2011.

The Company's largest recoverables from a single reinsurer at December 31, 2012, including prepaid reinsurance premiums, were approximately $2.7 billion from subsidiaries of Berkshire Hathaway Group, $900 million from subsidiaries of Swiss Re Group, and $350 million from subsidiaries of the Hartford Insurance Group. The recoverable from the Berkshire Hathaway Group includes amounts related to third party reinsurance for which a subsidiary of Berkshire Hathaway has assumed the credit risk under the terms of the Loss Portfolio Transfer as discussed in Note G.

Note K. Benefit Plans

Pension and Postretirement Health Care Benefit Plans

CNA sponsors noncontributory pension plans, primarily through the CNA Retirement Plan, typically covering full-time employees age 21 and over that have completed at least one year or 1,000 hours of service.

Effective January 1, 2000, the CNA Retirement Plan was closed to new participants. Existing participants at that time were given a choice to either continue to accrue benefits under the CNA Retirement Plan or to cease accruals at December 31, 1999. Employees who chose to continue to accrue benefits under the plan will receive a benefit based on their years of credited service and highest 60 months of compensation at termination. Compensation is defined as regular salary, eligible bonuses and overtime. Employees who elected to cease accruals at December 31, 1999 received the present value of their accrued benefit in an accrued pension account that is credited with interest based on the annual rate of interest on 30-year Treasury securities. These employees also receive certain enhanced employer contributions in the CNA Savings and Capital Accumulation Plan.

CNA's funding policy for defined benefit pension plans is to make contributions in accordance with applicable governmental regulatory requirements with consideration of the funded status of the plans.

CNA provides certain health care benefits to eligible retired employees, their covered dependents and their beneficiaries primarily through the CNA Health and Group Benefits Program. These benefits have largely been eliminated for active employees.

Discount rate	2.800	%	3.750	%

111

Actuarial assumptions used for the CNA Retirement Plan and CNA Health and Group Benefits Program to determine net cost or benefit are set forth in the following table.

Actuarial Assumptions for Net Cost or Benefit

Years ended December 31	2012		2011		2010
Pension benefits
Discount rate	4.600	%	5.375	%	5.700	%
Expected long term rate of return	8.000		8.000		8.000
Rate of compensation increases	4.125		5.030		5.030
Postretirement benefits
Discount rate	3.750	%	4.375	%	4.875 / 5.500%

In determining the expected long term rate of return on plan assets assumption for the CNA Retirement Plan, CNA considered the historical performance of the benefit plan investment portfolio as well as long term market return expectations based on the investment mix of the portfolio.

The CNA Health and Group Benefits Program has limited its share of the health care trend rate to a cost-of-living adjustment of 4% per year. For all participants, the employer subsidy on health care costs will not increase by more than 4% per year. As a result, the assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation for the CNA Health and Group Benefits Program was 4% per year in 2012, 2011 and 2010.

The health care cost trend rate assumption may have a significant effect on the amount of the benefit obligation and periodic cost reported. An increase in the assumed health care cost trend rate of 1% in each year would have no significant impact on the Company's accumulated postretirement benefit obligation or the Company's aggregate net periodic postretirement benefit for 2012. A decrease in the assumed health care cost trend rate of 1% in each year would decrease the Company's accumulated postretirement benefit obligation as of December 31, 2012 by $3 million and would have no significant impact on the Company's aggregate net periodic postretirement benefit for 2012.

CNA employs a total return approach whereby a mix of equity and fixed maturity securities are used to maximize the long term return of plan assets for a prudent level of risk and to manage cash flows according to plan requirements. The intent of this strategy is to minimize the Company's expense related to funding the plan by outperforming plan liabilities over the long run. Risk tolerance is established after careful consideration of the plan liabilities, plan funded status and corporate financial conditions. The investment portfolio contains a diversified blend of fixed maturity, equity and short term securities. Alternative investments, including limited partnerships, are used to enhance risk adjusted long term returns while improving portfolio diversification. At December 31, 2012 the plan had committed approximately $41 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships. Derivatives may be used to gain market exposure in an efficient and timely manner. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.

The limited partnership investments are recorded at fair value, which represents the plan's share of net asset value of each partnership, as determined by the General Partner. Level 2 includes limited partnership investments which can be redeemed at net asset value in 90 days or less. Level 3 includes limited partnership investments with withdrawal provisions greater than 90 days, or for which withdrawals are not permitted until the termination of the partnership. Within hedge fund strategies, approximately 54% are equity related, 35% pursue a multi-strategy approach and 11% are focused on distressed investments at December 31, 2012.

The fair value of the insurance company guaranteed investment contracts is an estimate of the amount that would be received in an orderly sale to a market participant at the measurement date. The amount the plan would receive from the contract holder if the contracts were terminated is the primary input and is unobservable. The guaranteed investment contracts are therefore classified as Level 3 investments.

For a discussion of the fair value levels and the valuation methodologies used to measure fixed maturity securities, equities, derivatives and short term investments, see Note E.

In 2013, CNA expects to contribute $90 million to its pension plans and $6 million to its postretirement health care benefit plans.

Savings Plans

CNA sponsors savings plans, which are generally contributory plans that allow most employees to contribute a maximum of 20% of their eligible compensation, subject to certain limitations prescribed by the IRS. The Company contributes matching amounts to participants, amounting to 70% of the first 6% (35% of the first 6% in the first year of employment) of eligible compensation contributed by the employee. Employees vest in these contributions ratably over five years.

The CNA Savings and Capital Accumulation Plan allows employees to make contributions to an investment fund that is supported in part by an investment contract purchased from CAC. CAC will not accept any further deposits under this contract. The liability to the CNA Savings and Capital Accumulation Plan is included in Separate account liabilities and Policyholders' funds on the Consolidated Balance Sheets, and was $256 million and $381 million at December 31, 2012 and 2011.

As noted above, during 2000, CCC employees were required to make a choice regarding their continued participation in CNA's defined benefit pension plan. Employees who elected to forgo earning additional benefits in the defined benefit pension plan and all employees hired by CCC on or after January 1, 2000 receive a Company contribution of 3% or 5% of their eligible compensation, depending on their age. In addition, these employees are eligible to receive additional discretionary contributions of up to 2% of eligible compensation and an additional Company match of up to 80% of the first 6% of eligible compensation contributed by the employee. These additional contributions are made at the discretion of management and are contributed to participant accounts in the first quarter of the year following management's determination of the discretionary amounts. Employees vest in these contributions ratably over five years.

Benefit expense for the Company's savings plans was $70 million, $60 million and $61 million for the years ended December 31, 2012, 2011 and 2010.

Stock-Based Compensation

The CNAF Incentive Compensation Plan (the Plan), as amended and restated on January 1, 2010, authorizes the grant of stock-based compensation to certain management personnel for up to 6 million shares of CNAF's common stock. The Plan currently provides for awards of stock options, stock appreciation rights (SARs), restricted shares, performance-based restricted share units (RSUs) and performance share units. The number of shares available for the granting of stock-based compensation under the Plan as of December 31, 2012 was approximately 1.9 million.

The Company recorded stock-based compensation expense related to the Plan of $9 million, $6 million and $5 million for the years ended December 31, 2012, 2011 and 2010. The related income tax benefit recognized was $3 million, $2 million and $2 million. The compensation cost related to nonvested awards not yet recognized was $12 million, and the weighted average period over which it is expected to be recognized is 1.38 years at December 31, 2012.

Equity based compensation that is not fully vested prior to termination is generally forfeited upon termination, except as otherwise provided by contractual obligations. In addition, any such compensation that vested prior to termination is generally canceled immediately, except in cases of retirement, death or disability, and as otherwise provided by contractual obligations.

116

Stock Options and SARs

The exercise price of all stock options and SARs granted is based on the market value of the Company's common stock as of the date of grant. Stock options and SARs generally vest ratably over a four-year service period following date of grant and have a maximum term of ten years.

The fair value of granted stock options and SARs was estimated at the grant date using the Black-Scholes option-pricing model. The Black-Scholes model incorporates a risk free rate of return and various assumptions regarding the underlying common stock and the expected life of the securities granted. Different interest rates and assumptions were used for each grant, as appropriate based on date of grant.

The following table presents the significant assumptions used to estimate the fair value of granted stock options and SARs for the years ended December 31, 2012, 2011 and 2010.

Years ended December 31	2012		2011		2010
Weighted average expected life of the securities granted (in years)	5.68		5.61		5.61
Estimate of the underlying common stock's volatility	40.39	%	39.88	%	39.58	%
Expected dividend yield	2.1	%	1.5	%	—	%
Risk free interest rate	1.0	%	2.2	%	2.6	%

The following table presents activity for stock options and SARs under the Plan in 2012.

Share Awards

The fair value of share awards is based on the market value of the Company's common stock as of the date of grant. Share awards currently granted under the Plan include restricted shares, performance-based RSUs, and performance share units. Generally, restricted shares vest ratably over a four-year service period following the date of grant. Performance-based RSUs generally become payable within a range of 0% to 100% of the number of shares initially granted based upon the attainment of specific annual performance goals and vest ratably over a four-year service period following the date of grant. Performance share units become payable within a range of 0% to 200% of the number of shares initially granted based upon the attainment of specific performance goals achieved over a three year period.

The following table presents activity for restricted shares, performance-based RSUs and performance share units under the Plan in 2012.

Note L. Operating Leases, Commitments and Contingencies, and Guarantees

Operating Leases

The Company occupies office facilities under lease agreements that expire at various dates. In addition, data processing, office and transportation equipment is leased under agreements that expire at various dates. Most leases contain renewal options that provide for rent increases based on prevailing market conditions. Lease expenses for the years ended December 31, 2012, 2011 and 2010were $52 million, $50 million and $52 million. Sublease revenues for the years ended December 31, 2012, 2011 and 2010 were $2 million, $2 million and $3 million.

The table below presents the future minimum lease payments to be made under non-cancelable operating leases along with future minimum sublease receipts to be received on owned and leased properties at December 31, 2012.

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 December 31, 2012 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $111 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 $7 million at December 31, 2012, were $2 million in 2013, $2 million in 2014, and $3 million thereafter.

119

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 December 31, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $725 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 December 31, 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 December 31, 2012 and 2011, the Company had recorded liabilities of approximately $7 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 M. Stockholders’ Equity and Statutory Accounting Practices

2008 Senior Preferred

In 2008, the Company issued, and Loews purchased, $1.25 billion of CNAF non-voting cumulative senior preferred stock, which was approved by a special review committee of independent members of CNAF's Board of Directors. As of December 31, 2010, the preferred stock was redeemed in full.

CNAF used the majority of the proceeds from the 2008 Senior Preferred to increase the statutory surplus of its principal insurance subsidiary, CCC, through the purchase of a $1.0 billion surplus note of CCC. Surplus notes are financial instruments with a stated maturity date and scheduled interest payments, issued by insurance enterprises with the approval of the insurer’s domiciliary state. Surplus notes are treated as capital under statutory accounting. All payments of interest and principal on this note are subject to the prior approval of the Illinois Department of Insurance (the Department). The surplus note of CCC had a term of 30 years and accrued interest at a rate of 10% per year. Interest on the note was payable quarterly. In 2012, CCC received regulatory approval from the Department to repay the $250 million outstanding balance of the $1.0 billion surplus note to CNAF.

Common Stock Dividends

Dividends of $0.60 and $0.40 per share on CNA's common stock were declared and paid in 2012 and 2011. No common stock dividends were declared or paid in 2010.

Statutory Accounting Practices

CNAF’s insurance subsidiaries are domiciled in various jurisdictions. These subsidiaries prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions’ insurance regulators. Domestic prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners (NAIC) as well as state laws, regulations and general administrative rules. These statutory accounting principles vary in certain respects from GAAP. In converting from statutory accounting principles to GAAP, the more significant adjustments include deferral of policy acquisition costs and the inclusion of net unrealized holding gains or losses in stockholders’ equity relating to certain fixed maturity securities.

CNAF’s ability to pay dividends and other credit obligations is significantly dependent on receipt of dividends from CCC as it directly or indirectly owns all significant subsidiaries. The payment of dividends by CNAF's insurance subsidiaries without prior approval of the insurance department of each subsidiary’s domiciliary jurisdiction is generally limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective insurance regulator.

Dividends from CCC are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Department, may be paid only from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of December 31, 2012, CCC is in a positive earned surplus position, enabling CCC to pay approximately $550 million of dividend payments during 2013 that would not be subject to the Department’s prior approval. The actual level of dividends paid in any year is determined after an assessment of available dividend capacity, holding company liquidity and cash needs as well as the impact the dividends will have on the statutory surplus of the applicable insurance company.

121

CNAF’s domestic insurance subsidiaries are subject to risk-based capital requirements. Risk-based capital is a method developed by the NAIC to determine the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of risk-based capital specifies various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. The adequacy of a company's actual capital is evaluated by a comparison to the risk-based capital results, as determined by the formula. Companies below minimum risk-based capital requirements are classified within certain levels, each of which requires specified corrective action. As of December 31, 2012 and 2011, all of CNAF’s domestic insurance subsidiaries exceeded the minimum risk-based capital requirements.

Subsidiaries with insurance operations outside the United States are also subject to insurance regulation in the countries in which they operate. The Company has legal entity and branch operations in other countries, primarily the United Kingdom, Canada and Bermuda. CNAF’s foreign legal entities and branch met or exceeded their respective regulatory and other capital requirements.

Combined statutory capital and surplus and net income (loss), determined in accordance with accounting practices prescribed or permitted by insurance and/or other regulatory authorities for the Combined Continental Casualty Companies and the life company, were as follows.

Statutory Information

	Statutory Capital and Surplus				Statutory Net Income (Loss)

________________

(a) Represents the combined statutory surplus of CCC and its subsidiaries, including the life company.

(b) Information derived from the statutory-basis financial statements to be filed with insurance regulators.

The Hardy insurance entities are not owned by CCC, therefore their regulatory capital is not included in the Statutory Capital and Surplus of the Combined Continental Casualty Companies presented in the table above. At December 31, 2012, Hardy's portion of Syndicate 382's capital requirement was approximately $330 million, which included $66 million of capital provided by CCC and included in Combined Continental Casualty Companies' Statutory Capital and Surplus above.

Note N. Accumulated Other Comprehensive Income (Loss)

The following table displays the components of AOCI included on the Consolidated Balance Sheets.

Accumulated Other Comprehensive Income (Loss)

The amount of pretax net unrealized gains (losses) on available-for-sale securities with OTTI losses reclassified out of AOCI and recognized in earnings was $(28) million, $(83) million and $(42) million for the years ended December 31, 2012, 2011 and 2010, with related tax benefit of $10 million, $29 million and $15 million. The amount of pretax net unrealized gains (losses) on other available-for-sale securities reclassified out of AOCI and recognized in earnings was $89 million, $60 million and $137 million for the years ended December 31, 2012, 2011 and 2010, with related tax (expense) benefit of $(31) million, $(21) million and $(48) million.

123

Note O. Business Segments

The Company's core property and casualty commercial insurance operations are reported in three business segments: CNA Specialty, CNA Commercial and Hardy. CNA Specialty provides a broad array of professional, financial and specialty property and casualty products and services, primarily through insurance brokers and managing general underwriters. CNA Commercial includes property and casualty coverages sold to small businesses and middle market entities and organizations primarily through an independent agency distribution system. CNA Commercial also includes commercial insurance and risk management products sold to large corporations primarily through insurance brokers. Hardy, a specialized Lloyd's underwriter, underwrites primarily short-tail exposures in marine and aviation, non-marine property, specialty lines and property treaty reinsurance.

The Company's non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core. Life & Group Non-Core primarily includes the results of the life and group lines of business that are in run-off. Corporate & Other Non-Core primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP.

The accounting policies of the segments are the same as those described in Note A. 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, deferred acquisition costs, and goodwill 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.

Approximately 9.2%, 8.8% and 6.9% of the Company's direct written premiums were derived from outside the United States for the years ended December 31, 2012, 2011 and 2010.

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.

Note R. Related Party Transactions

The Company reimburses Loews, or pays directly, for management fees, travel and related expenses, software fees, and expenses of investment facilities and services provided to the Company. The amounts reimbursed or paid by the Company were $39 million, $38 million and $38 million for the years ended December 31, 2012, 2011 and 2010. The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. See Note F for a detailed description of the income tax agreement with Loews. In addition, the Company writes, at standard rates, a limited amount of insurance for Loews and its subsidiaries. The earned premiums for the years ended December 31, 2012, 2011 and 2010 were $2 million in each year.

CNA previously sponsored a stock ownership plan whereby the Company financed the purchase of Company common stock by certain former officers, including executive officers. Interest charged on the principal amount of these outstanding stock purchase loans is generally equivalent to the short term applicable federal rate, compounded semi-annually, in effect on the disbursement date of the loan. Loans made pursuant to the plan are generally full recourse and are secured by the stock purchased. The loans were originally issued with a ten-year maturity date, and the majority of the remaining loans have been extended with current terms maturing through August 2015. The carrying value of the loans as of December 31, 2012 approximates the fair value of the related common stock collateral.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

CNA Financial Corporation

Chicago, Illinois

We have audited the accompanying consolidated balance sheets of CNA Financial Corporation (an affiliate of Loews Corporation) and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and stockholders' equity for each of the three years in the period ended December 31, 2012. Our audits also included the financial statement schedules listed in the Index at Item 15. We also have audited the Company's internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management's Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Hardy Underwriting Bermuda Limited and its subsidiaries (“Hardy”), which was acquired on July 2, 2012 and whose financial statements constitute $1,217 million of total assets, $123 million of revenues, and $24 million of net loss of the consolidated financial statement amounts as of and for the year ended December 31, 2012. Accordingly, our audit did not include the internal control over financial reporting at Hardy. The Company's management is responsible for these financial statements and financial statement schedules, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and financial statement schedules and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

131

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

As discussed in Note A to the consolidated financial statements, the Company changed its accounting for costs associated with acquiring or renewing insurance contracts in 2012.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of CNA Financial Corporation (CNAF or the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. CNAF's internal control system was designed to provide reasonable assurance to the Company's management, its Audit Committee and Board of Directors regarding the preparation and fair presentation of published financial statements.

There are inherent limitations to the effectiveness of any internal control or system of control, however well designed, including the possibility of human error and the possible circumvention or overriding of such controls or systems. Moreover, because of changing conditions the reliability of internal controls may vary over time. As a result even effective internal controls can provide no more than reasonable assurance with respect to the accuracy and completeness of financial statements and their process of preparation.

CNAF management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2012. In making this assessment, it has used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. Based on those criteria and our assessment we believe that, as of December 31, 2012, the Company's internal control over financial reporting was effective.

On July 2, 2012, the Company completed the acquisition of Hardy. Hardy's existing disclosure controls and procedures supported their financial reporting as a separate publicly-traded company. In conducting its evaluation of the effectiveness of the Company's internal control over financial reporting, CNAF management elected to exclude Hardy from this evaluation as permitted under SEC rules. As of and for the year ended December 31, 2012, Hardy constituted approximately $1,217 million of total assets, $123 million of revenues and $24 million of net loss of the consolidated financial statement amounts. The Company is currently in the process of evaluating and integrating Hardy's controls over financial reporting. CNAF management expects to complete this integration by June 30, 2013.

CNAF's independent registered public accountant, Deloitte & Touche LLP, has issued an audit report on the Company's internal control over financial reporting. This report appears on page 131.

ITEM 9A. CONTROLS AND PROCEDURES

As of December 31, 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 Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, and the implementing rules of the Securities and Exchange Commission, the Company included a report of management's assessment of the design and effectiveness of its internal controls as part of this Annual Report on Form 10-K for the fiscal year ended December 31, 2012. Management's report and the independent registered public accounting firm's attestation report are included in Part II, Item 8 under the captions entitled “Management's Report on Internal Control Over Financial Reporting” and “Report of Independent Registered Public Accounting Firm” and are incorporated herein by reference.

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 December 31, 2012 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

On July 2, 2012, the Company completed the acquisition of Hardy. Hardy's existing disclosure controls and procedures supported their financial reporting as a separate publicly-traded company. In conducting its evaluation of the effectiveness of the Company's internal control over financial reporting, CNAF management elected to exclude Hardy from this evaluation as permitted under SEC rules. As of and for the year ended December 31, 2012, Hardy constituted approximately $1,217 million of total assets, $123 million of revenues and $24 million of net loss of the consolidated financial statement amounts. The Company is currently in the process of evaluating and integrating Hardy's controls over financial reporting. CNAF management expects to complete this integration by June 30, 2013.

Notes to Condensed Financial Information

A. Basis of Presentation

The condensed financial information of CNA Financial Corporation (CNAF or the Parent Company) should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Item 8 of this Form 10-K. CNAF’s subsidiaries are accounted for using the equity method of accounting. Equity in net income of these subsidiaries is presented on the Condensed Statements of Operations as Equity in net income of subsidiaries. Loews owned approximately 90% of the outstanding common stock of CNAF as of December 31, 2012.

B. Commitments, Contingencies and Guarantees

In the normal course of business, CNAF guarantees the indebtedness of certain of its subsidiaries to the debt maturity or payoff, whichever comes first. These guarantees arise in the normal course of business and are given to induce a lender to enter into an agreement with CNAF’s subsidiaries. CNAF would be required to remit prompt and complete payment when due, should the primary obligor default. The maximum potential amount of future payments that CNAF could be required to pay under these guarantees are approximately $10 million at December 31, 2012. The Parent Company does not believe that a payable is likely under these guarantees.

In the course of selling business entities and assets to third parties, CNAF 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 December 31, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $257 million.

In addition, CNAF 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 December 31, 2012, CNAF 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 December 31, 2012, CNAF has no recorded liabilities related to indemnification agreements. The Parent Company does not believe that any indemnity claim payments are likely.

In the normal course of business, CNAF has provided guarantees to holders of structured settlement annuities (SSA) provided by certain of its subsidiaries, which expire through 2120. CNAF would be required to remit SSA payments due to claimants if the primary obligor failed to perform on these contracts. The maximum potential amount of future payments that CNAF could be required to pay under these guarantees are approximately $1.9 billion at December 31, 2012. The Parent Company does not believe that a payable is likely under these guarantees.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Accounting Policies [Abstract]

Consolidation

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated.

Use of Estimates

The preparation of 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 Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

Discontinued Operations

The Company has historically reported certain run-off insurance operations acquired in its merger with The Continental Corporation in 1995 as discontinued operations. Due to the immateriality of the remaining liabilities, effective in the third quarter of 2011, the Company is no longer reporting these run-off operations as discontinued operations.

Premiums

Premiums: Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured which principally are earned ratably over the duration of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.

Insurance receivables include balances due currently or in the future, including amounts due from insureds related to losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. Amounts are considered past due based on policy payment terms. That allowance is determined based on periodic evaluations of aged receivables, management's experience and current economic conditions. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached.

Property and casualty contracts that are retrospectively rated contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions and loss experience of the insured during the experience period. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the experience period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company adjusts such estimated ultimate premium amounts during the course of the experience period based on actual results to date. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.

Claim and claim adjustment expense reserves

Claim and claim adjustment expense reserves: Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (A&EP), workers' compensation lifetime claims, and accident and health claims, are not discounted and are based on 1) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; 2) estimates of incurred but not reported (IBNR) losses; 3) estimates of losses on assumed reinsurance; 4) estimates of future expenses to be incurred in the settlement of claims; 5) estimates of salvage and subrogation recoveries and 6) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets.

Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $1.3 billion and $1.4 billion as of December 31, 2012 and 2011. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on the Consolidated Balance Sheets.

Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. Certain structured settlements are funded by annuities purchased from Continental Assurance Company (CAC) for which the related annuity obligations are reported in Future policy benefits reserves. Obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and carried at present values determined using interest rates ranging from 7.1% to 9.7% at December 31, 2012 and 5.5% to 8.0% at December 31, 2011. At December 31, 2012 and 2011, the discounted reserves for unfunded structured settlements were $602 million and $632 million, net of discount of $1.0 billion and $1.1 billion.

Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. Accident and health claim reserves are calculated using mortality and morbidity assumptions based on Company and industry experience. Workers' compensation lifetime claim reserves and accident and health claim reserves are discounted at interest rates ranging from 3.0% to 6.5% at both December 31, 2012 and 2011. At December 31, 2012 and 2011, such discounted reserves totaled $2.2 billion and $2.1 billion, net of discount of $837 million and $520 million.

Future policy benefits reserves: Reserves for long term care products and payout annuity contracts are computed using the net level premium method, which incorporates actuarial assumptions as to morbidity, mortality, persistency, discount rates, which are impacted by expected investment yields, and expenses. Expense assumptions include the estimated effects of expenses to be incurred beyond the premium paying period. Actuarial assumptions generally vary by plan, age at issue and policy duration. The initial assumptions are determined at issuance, include a margin for adverse deviation, and are locked in throughout the life of the contract unless a premium deficiency develops. If a premium deficiency emerges, the assumptions are unlocked and deferred acquisition costs, if any, and the future policy benefit reserves are adjusted. Interest rates for long-term care products range from 5.0% to 7.4% at December 31, 2012 and from 5.0% to 7.5% at December 31, 2011. Interest rates for payout annuity contracts range from 5.0% to 8.7% at December 31, 2012 and from 5.4% to 7.5% at December 31, 2011. In 2012, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in discount rates, which reflect the current low interest rate environment and our view of expected investment yields, resulting in loss recognition which increased insurance liabilities by $33 million. In 2011, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in mortality and discount rates, resulting in loss recognition which increased insurance reserves by $166 million.

Policyholders' funds reserves

Policyholders' funds reserves: Policyholders' funds reserves primarily include reserves for investment contracts without life contingencies. For these contracts, policyholder liabilities are generally equal to the accumulated policy account values, which consist of an accumulation of deposit payments plus credited interest, less withdrawals and amounts assessed through the end of the period.

Guaranty fund and other insurance-related assessments

Guaranty fund and other insurance-related assessments: Liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated, and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for guaranty funds and other insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2012 and 2011, the liability balances were $143 million and $152 million. As of December 31, 2012 and 2011, included in Other assets on the Consolidated Balance Sheets were $2 million of related assets for premium tax offsets. This asset is limited to the amount that is able to be offset against premium tax on future premium collections from business written or committed to be written.

Reinsurance

Reinsurance: Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.

Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. Reinsurance receivables are reported net of an allowance for uncollectible amounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of the Company.

The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The allowance for uncollectible reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, management's experience and current economic conditions. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if the Company becomes aware of significant changes related to a reinsurer. Because billed receivables are generally 5% or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for uncollectible reinsurance receivables are presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables related to paid losses from insolvent insurers are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Reinsurance contracts that do not effectively transfer the economic risk of loss on the underlying policies are recorded using the deposit method of accounting, which requires that premium paid or received by the ceding company or assuming company be accounted for as a deposit asset or liability. The Company had $3 million and $18 million recorded as deposit assets at December 31, 2012 and 2011, and $125 million and $123 million recorded as deposit liabilities at December 31, 2012 and 2011. Income on reinsurance contracts accounted for under the deposit method is recognized using an effective yield based on the anticipated timing of payments and the remaining life of the contract. When the anticipated timing of payments changes, the effective yield is recalculated to reflect actual payments to date and the estimated timing of future payments. The deposit asset or liability is adjusted to the amount that would have existed had the new effective yield been applied since the inception of the contract.

Participating insurance

Participating insurance: Policyholder dividends are accrued using an estimate of the amount to be paid based on underlying contractual obligations under policies and applicable state laws. Limitations exist on the amount of income from participating life insurance contracts that may be distributed to stockholders, and therefore the share of income on these policies that cannot be distributed to stockholders is excluded from Stockholders' equity by a charge to operations and other comprehensive income and the establishment of a corresponding liability.

Deferred acquisition costs

Deferred acquisition costs: Acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Deferred acquisition costs related to long term care contracts issued prior to January 1, 2004 include costs which vary with and are primarily related to the acquisition of business, as further discussed at the Accounting Standards Update section of this note.

Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned.

Deferred acquisition costs related to long term care contracts are 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. Assumptions are made at the date of policy issuance or acquisition and are consistently applied during the lives of the contracts. Deviations from estimated experience are included in results of operations when they occur. For these contracts, the amortization period is typically the estimated life of the policy. At December 31, 2012 and 2011, Deferred acquisition costs were presented net of Shadow Adjustments, as defined later in this note, of $369 million and $398 million.

The Company evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current results of operations.

Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs. Unamortized deferred acquisition costs relating to contracts that have been substantially changed by a modification in benefits, features, rights or coverages that were not anticipated in the original contract are not deferred and are included as a charge to operations in the period during which the contract modification occurred.

Investments in life settlement contracts and related revenue recognition

Investments in life settlement contracts and related revenue recognition: Prior to 2002, the Company purchased investments in life settlement contracts. A life settlement contract is a contract between the owner of a life insurance policy (the policy owner) and a third-party investor (investor). Under a life settlement contract, the Company obtains the ownership and beneficiary rights of an underlying life insurance policy.

The Company accounts for its investments in life settlement contracts using the fair value method. Under the fair value method, each life settlement contract is carried at its fair value at the end of each reporting period. The change in fair value, life insurance proceeds received and periodic maintenance costs, such as premiums, necessary to keep the underlying policy in force, are recorded in Other revenues on the Consolidated Statements of Operations. The fair value of the Company's investments in life settlement contracts were $100 million and $117 million at December 31, 2012 and 2011, and are included in Other assets on the Consolidated Balance Sheets. The cash receipts and payments related to life settlement contracts are included in Cash flows from operating activities on the Consolidated Statements of Cash Flows.

The following table details the values for life settlement contracts. The determination of fair value is discussed in Note E.

December 31, 2012	Number of Life Settlement Contracts	Fair Value of Life Settlement Contracts (In millions)		Face Amount of Life Insurance Policies (In millions)
Estimated maturity during:
2013	70	$	15	$	41
2014	60	13		36
2015	60	11		34
2016	50	9		30
2017	40	7		27
Thereafter	390	45		237
Total	670	$	100	$	405

The Company uses an actuarial model to estimate the aggregate face amount of life insurance that is expected to mature in each future year and the corresponding fair value. This model projects the likelihood of the insured's death for each inforce policy based upon the Company's estimated mortality rates, which may vary due to the relatively small size of the portfolio of life settlement contracts. The number of life settlement contracts presented in the table above is based upon the average face amount of inforce policies estimated to mature in each future year.

The increase in fair value recognized for the years ended December 31, 2012, 2011 and 2010 on contracts still being held was $11 million, $5 million and $10 million. The gains recognized during the years ended December 31, 2012, 2011 and 2010 on contracts that settled were $42 million, $28 million and $19 million.

Separate Account Business

Separate Account Business: Separate account assets and liabilities represent contract holder funds related to investment and annuity products for which the policyholder assumes substantially all the risk and reward. The assets are segregated into accounts with specific underlying investment objectives and are legally segregated from the Company. All assets of the separate account business are carried at fair value with an equal amount recorded for separate account liabilities. Fee income accruing to the Company related to separate accounts is primarily included within Other revenues on the Consolidated Statements of Operations.

A number of separate account pension deposit contracts guarantee principal and an annual minimum rate of interest. If aggregate contract value in the separate account exceeds the fair value of the related assets, an additional Policyholders' funds liability is established. During 2012 and 2010, the Company decreased this pretax Policyholders' funds liability by $20 million and $24 million. The Company increased this pretax Policyholders' funds liability by $18 million in 2011. Certain of these contracts are subject to a fair value adjustment if terminated by the policyholder.

Investments

Investments

The Company classifies its fixed maturity securities and its equity securities as either available-for-sale or trading, and as such, they are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Operations. Changes in fair value related to available-for-sale securities are reported as a component of Other comprehensive income. The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity, which are included in Net investment income on the Consolidated Statements of Operations. Losses may be recognized within Net realized investment gains (losses) on the Consolidated Statements of Operations when a decline in value is determined by the Company to be other-than-temporary.

To the extent that unrealized gains on fixed income securities supporting long term care products and payout annuity contracts would result in a premium deficiency if those gains were realized, a related decrease in Deferred acquisition costs and/or increase in Insurance reserves are recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (Shadow Adjustments). For the years ended December 31, 2012 and 2011, Shadow Adjustments, net of participating policyholders' interest, of $789 million and $572 million, were recorded, net of tax. At December 31, 2012 and 2011, net unrealized gains on investments included in Accumulated other comprehensive income (AOCI) were correspondingly reduced by $1,511 million and $722 million.

For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The amortized cost of high credit quality securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reflected in Net investment income on the Consolidated Statements of Operations. Interest income on lower rated securities is determined using the prospective yield method.

The Company's carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the General Partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. Changes in net asset values are accounted for under the equity method and recorded within Net investment income on the Consolidated Statements of Operations.

Mortgage loans are commercial in nature, are carried at unpaid principal balance, net of unamortized fees and any valuation allowance, and are recorded once funded. Mortgage loans are considered to be impaired loans when it is probable that contractual principal and interest payments will not be collected. A valuation allowance is established for impaired loans to the extent that the present value of expected future cash flows discounted at the loan's original effective interest rate is less than the carrying value of the loan. Interest income from mortgage loans is recognized on an accrual basis using the effective yield method. Accrual of income is generally suspended for mortgage loans that are impaired and collection of principal and interest payments is unlikely. Mortgage loans are considered past due when full principal or interest payments have not been received according to contractual terms.

Other invested assets are carried at fair value and include overseas deposits, certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected. Overseas deposits are primarily short-term government securities, agency securities, and corporate bonds held in trusts that are managed by Lloyd's of London (Lloyd's). These funds are required of Lloyd's syndicates to protect policyholders in overseas markets and may be denominated in local currency. Changes in fair value of overseas deposits are reflected in Net investment income on the Consolidated Statements of Operations. Changes in fair value of certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected are reported in Net realized investment gains (losses) in the Consolidated Statements of Operations.

Short term investments are carried at fair value, with the exception of cash accounts earning interest, which are carried at cost and approximate fair value. Changes in fair value are reported as a component of Other comprehensive income.

Purchases and sales of all securities are recorded on the trade date, except for private placement debt securities, including bank loan participations, which are recorded once funded. Realized investment gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.

Income Taxes

Income Taxes

The Company and its eligible subsidiaries (CNA Tax Group) are included in the consolidated federal income tax return of Loews and its eligible subsidiaries. The Company accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized.

Pension and Postretirement Benefits

Pension and Postretirement Benefits

The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities on the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits and actuarial gains and losses are recognized in the year in which the changes occur through Other comprehensive income. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits, and amortization of actuarial gains and losses are recognized on the Consolidated Statements of Operations.

Stock-Based Compensation

Stock-Based Compensation

The Company records compensation expense using the fair value method for all awards it grants, modifies, repurchases or cancels primarily on a straight-line basis over the requisite service period, generally four years.

Foreign Currency

Foreign Currency

Foreign currency translation gains and losses are reflected in Stockholders' equity as a component of Accumulated other comprehensive income. The Company's foreign subsidiaries' balance sheet accounts are translated at the exchange rates in effect at each year end and income statement accounts are either translated at the exchange rate on the date of the transaction or at the average exchange rates. Foreign currency transaction gains (losses) of $12 million, $4 million and $(19) million were included in determining net income (loss) for the years ended December 31, 2012, 2011 and 2010.

Property and Equipment

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is determined principally on the straight-line method. Furniture and fixtures are depreciated over seven years. Office equipment is depreciated over five years. The estimated lives for data processing equipment and software range from three to five years. Leasehold improvements are depreciated over the corresponding lease terms not to exceed the underlying asset life. The Company's owned buildings, and related capital improvements, are depreciated over periods not to exceed fifty years.

Goodwill

Goodwill

Goodwill represents the excess of purchase price over the fair value of the net assets of acquired entities and businesses. Goodwill related to Hardy may change from period to period as a result of foreign currency translation. Goodwill is tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the goodwill recognized as part of the acquisition of Hardy.

Intangible Assets

Intangible Assets

Intangible assets are reported within Other assets. As of December 31, 2012, the Company's finite-lived intangible assets were $40 million. The Company had no finite-lived intangible assets at December 31, 2011. Finite-lived intangible assets are amortized over their estimated useful lives. As of December 31, 2012, and 2011, the Company's indefinite-lived intangible assets were $73 million and $16 million. Indefinite-lived intangible assets are tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the intangible assets acquired as part of the acquisition of Hardy.

Earnings (Loss) Per Share Data

Earnings (Loss) Per Share Data

Earnings (loss) per share attributable to the Company's common stockholders is based on 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 years ended December 31, 2012, 2011, and 2010, approximately 417 thousand, 290 thousand and 380 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 730 thousand, 1.1 million and 1.2 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.

Accounting Standards Updates

Accounting Standards Updates

Adopted

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 year ended December 31, 2012, the adoption of the new accounting guidance resulted in a $5 million decrease in Net income attributable to CNA and a $0.02 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 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 and the Company's acquisition of the noncontrolling interest of Surety as discussed above.

The impacts on the Company's Consolidated Statements of Operations for the years ended December 31, 2011 and 2010 were a $2 million increase and no impact in Other net realized investment gains, a $234 million and $219 million decrease in Amortization of deferred acquisition costs, a $242 million and $219 million increase in Other operating expenses, a $4 million and $1 million decrease in Income tax expense, resulting in a $2 million decrease and a $1 million increase in Net income attributable to CNA, and a $0.01 decrease and no impact 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.

Derivative Securities

Derivative securities are recorded at fair value. See Note E for information regarding the fair value of derivative securities. Changes in the fair value of derivatives not associated with the trading portfolio are reported in Net realized investment gains (losses) on the Consolidated Statements of Operations. Changes in the fair value of derivatives associated with the trading portfolio are reported in Net investment income on the Consolidated Statements of Operations.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note A. Summary of Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of December 31, 2012.

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. The preparation of 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 Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The Company has historically reported certain run-off insurance operations acquired in its merger with The Continental Corporation in 1995 as discontinued operations. Due to the immateriality of the remaining liabilities, effective in the third quarter of 2011, the Company is no longer reporting these run-off operations as discontinued operations.

Business

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

The Company serves a wide variety of customers, including small, medium and large businesses; insurance companies; associations; professionals; groups; and individuals with a broad range of insurance and risk management products and services.

Core insurance products include commercial property and casualty coverages, including surety. Non-core insurance products, which primarily have been placed in run-off, include life and accident and health insurance and retirement products and annuities. CNA services include risk management, information services, warranty and claims administration. The Company's products and services are primarily marketed through independent agents, brokers, and managing general underwriters.

Noncontrolling Interests

Net income attributable to noncontrolling interests for the years ended December 31, 2011 and 2010 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.

Insurance Operations

Premiums: Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured which principally are earned ratably over the duration of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.

Insurance receivables include balances due currently or in the future, including amounts due from insureds related to losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. Amounts are considered past due based on policy payment terms. That allowance is determined based on periodic evaluations of aged receivables, management's experience and current economic conditions. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached.

Property and casualty contracts that are retrospectively rated contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions and loss experience of the insured during the experience period. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the experience period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company adjusts such estimated ultimate premium amounts during the course of the experience period based on actual results to date. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.

Claim and claim adjustment expense reserves: Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (A&EP), workers' compensation lifetime claims, and accident and health claims, are not discounted and are based on 1) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; 2) estimates of incurred but not reported (IBNR) losses; 3) estimates of losses on assumed reinsurance; 4) estimates of future expenses to be incurred in the settlement of claims; 5) estimates of salvage and subrogation recoveries and 6) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets.

Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $1.3 billion and $1.4 billion as of December 31, 2012 and 2011. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on the Consolidated Balance Sheets.

Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. Certain structured settlements are funded by annuities purchased from Continental Assurance Company (CAC) for which the related annuity obligations are reported in Future policy benefits reserves. Obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and carried at present values determined using interest rates ranging from 7.1% to 9.7% at December 31, 2012 and 5.5% to 8.0% at December 31, 2011. At December 31, 2012 and 2011, the discounted reserves for unfunded structured settlements were $602 million and $632 million, net of discount of $1.0 billion and $1.1 billion.

Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. Accident and health claim reserves are calculated using mortality and morbidity assumptions based on Company and industry experience. Workers' compensation lifetime claim reserves and accident and health claim reserves are discounted at interest rates ranging from 3.0% to 6.5% at both December 31, 2012 and 2011. At December 31, 2012 and 2011, such discounted reserves totaled $2.2 billion and $2.1 billion, net of discount of $837 million and $520 million.

Future policy benefits reserves: Reserves for long term care products and payout annuity contracts are computed using the net level premium method, which incorporates actuarial assumptions as to morbidity, mortality, persistency, discount rates, which are impacted by expected investment yields, and expenses. Expense assumptions include the estimated effects of expenses to be incurred beyond the premium paying period. Actuarial assumptions generally vary by plan, age at issue and policy duration. The initial assumptions are determined at issuance, include a margin for adverse deviation, and are locked in throughout the life of the contract unless a premium deficiency develops. If a premium deficiency emerges, the assumptions are unlocked and deferred acquisition costs, if any, and the future policy benefit reserves are adjusted. Interest rates for long-term care products range from 5.0% to 7.4% at December 31, 2012 and from 5.0% to 7.5% at December 31, 2011. Interest rates for payout annuity contracts range from 5.0% to 8.7% at December 31, 2012 and from 5.4% to 7.5% at December 31, 2011. In 2012, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in discount rates, which reflect the current low interest rate environment and our view of expected investment yields, resulting in loss recognition which increased insurance liabilities by $33 million. In 2011, the Company unlocked assumptions related to its payout annuity contracts due to anticipated adverse changes in mortality and discount rates, resulting in loss recognition which increased insurance reserves by $166 million.

Policyholders' funds reserves: Policyholders' funds reserves primarily include reserves for investment contracts without life contingencies. For these contracts, policyholder liabilities are generally equal to the accumulated policy account values, which consist of an accumulation of deposit payments plus credited interest, less withdrawals and amounts assessed through the end of the period.

Guaranty fund and other insurance-related assessments: Liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated, and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for guaranty funds and other insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2012 and 2011, the liability balances were $143 million and $152 million. As of December 31, 2012 and 2011, included in Other assets on the Consolidated Balance Sheets were $2 million of related assets for premium tax offsets. This asset is limited to the amount that is able to be offset against premium tax on future premium collections from business written or committed to be written.

Reinsurance: Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.

Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. Reinsurance receivables are reported net of an allowance for uncollectible amounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of the Company.

The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The allowance for uncollectible reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, management's experience and current economic conditions. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if the Company becomes aware of significant changes related to a reinsurer. Because billed receivables are generally 5% or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for uncollectible reinsurance receivables are presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables related to paid losses from insolvent insurers are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.

Reinsurance contracts that do not effectively transfer the economic risk of loss on the underlying policies are recorded using the deposit method of accounting, which requires that premium paid or received by the ceding company or assuming company be accounted for as a deposit asset or liability. The Company had $3 million and $18 million recorded as deposit assets at December 31, 2012 and 2011, and $125 million and $123 million recorded as deposit liabilities at December 31, 2012 and 2011. Income on reinsurance contracts accounted for under the deposit method is recognized using an effective yield based on the anticipated timing of payments and the remaining life of the contract. When the anticipated timing of payments changes, the effective yield is recalculated to reflect actual payments to date and the estimated timing of future payments. The deposit asset or liability is adjusted to the amount that would have existed had the new effective yield been applied since the inception of the contract.

Participating insurance: Policyholder dividends are accrued using an estimate of the amount to be paid based on underlying contractual obligations under policies and applicable state laws. Limitations exist on the amount of income from participating life insurance contracts that may be distributed to stockholders, and therefore the share of income on these policies that cannot be distributed to stockholders is excluded from Stockholders' equity by a charge to operations and other comprehensive income and the establishment of a corresponding liability.

Deferred acquisition costs: Acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Deferred acquisition costs related to long term care contracts issued prior to January 1, 2004 include costs which vary with and are primarily related to the acquisition of business, as further discussed at the Accounting Standards Update section of this note.

Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned.

Deferred acquisition costs related to long term care contracts are 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. Assumptions are made at the date of policy issuance or acquisition and are consistently applied during the lives of the contracts. Deviations from estimated experience are included in results of operations when they occur. For these contracts, the amortization period is typically the estimated life of the policy. At December 31, 2012 and 2011, Deferred acquisition costs were presented net of Shadow Adjustments, as defined later in this note, of $369 million and $398 million.

The Company evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current results of operations.

Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs. Unamortized deferred acquisition costs relating to contracts that have been substantially changed by a modification in benefits, features, rights or coverages that were not anticipated in the original contract are not deferred and are included as a charge to operations in the period during which the contract modification occurred.

Investments in life settlement contracts and related revenue recognition: Prior to 2002, the Company purchased investments in life settlement contracts. A life settlement contract is a contract between the owner of a life insurance policy (the policy owner) and a third-party investor (investor). Under a life settlement contract, the Company obtains the ownership and beneficiary rights of an underlying life insurance policy.

The Company accounts for its investments in life settlement contracts using the fair value method. Under the fair value method, each life settlement contract is carried at its fair value at the end of each reporting period. The change in fair value, life insurance proceeds received and periodic maintenance costs, such as premiums, necessary to keep the underlying policy in force, are recorded in Other revenues on the Consolidated Statements of Operations. The fair value of the Company's investments in life settlement contracts were $100 million and $117 million at December 31, 2012 and 2011, and are included in Other assets on the Consolidated Balance Sheets. The cash receipts and payments related to life settlement contracts are included in Cash flows from operating activities on the Consolidated Statements of Cash Flows.

The following table details the values for life settlement contracts. The determination of fair value is discussed in Note E.

December 31, 2012	Number of Life Settlement Contracts	Fair Value of Life Settlement Contracts (In millions)		Face Amount of Life Insurance Policies (In millions)
Estimated maturity during:
2013	70	$	15	$	41
2014	60	13		36
2015	60	11		34
2016	50	9		30
2017	40	7		27
Thereafter	390	45		237
Total	670	$	100	$	405

The Company uses an actuarial model to estimate the aggregate face amount of life insurance that is expected to mature in each future year and the corresponding fair value. This model projects the likelihood of the insured's death for each inforce policy based upon the Company's estimated mortality rates, which may vary due to the relatively small size of the portfolio of life settlement contracts. The number of life settlement contracts presented in the table above is based upon the average face amount of inforce policies estimated to mature in each future year.

The increase in fair value recognized for the years ended December 31, 2012, 2011 and 2010 on contracts still being held was $11 million, $5 million and $10 million. The gains recognized during the years ended December 31, 2012, 2011 and 2010 on contracts that settled were $42 million, $28 million and $19 million.

Separate Account Business: Separate account assets and liabilities represent contract holder funds related to investment and annuity products for which the policyholder assumes substantially all the risk and reward. The assets are segregated into accounts with specific underlying investment objectives and are legally segregated from the Company. All assets of the separate account business are carried at fair value with an equal amount recorded for separate account liabilities. Fee income accruing to the Company related to separate accounts is primarily included within Other revenues on the Consolidated Statements of Operations.

A number of separate account pension deposit contracts guarantee principal and an annual minimum rate of interest. If aggregate contract value in the separate account exceeds the fair value of the related assets, an additional Policyholders' funds liability is established. During 2012 and 2010, the Company decreased this pretax Policyholders' funds liability by $20 million and $24 million. The Company increased this pretax Policyholders' funds liability by $18 million in 2011. Certain of these contracts are subject to a fair value adjustment if terminated by the policyholder.

The Company classifies its fixed maturity securities and its equity securities as either available-for-sale or trading, and as such, they are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Operations. Changes in fair value related to available-for-sale securities are reported as a component of Other comprehensive income. The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity, which are included in Net investment income on the Consolidated Statements of Operations. Losses may be recognized within Net realized investment gains (losses) on the Consolidated Statements of Operations when a decline in value is determined by the Company to be other-than-temporary.

To the extent that unrealized gains on fixed income securities supporting long term care products and payout annuity contracts would result in a premium deficiency if those gains were realized, a related decrease in Deferred acquisition costs and/or increase in Insurance reserves are recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (Shadow Adjustments). For the years ended December 31, 2012 and 2011, Shadow Adjustments, net of participating policyholders' interest, of $789 million and $572 million, were recorded, net of tax. At December 31, 2012 and 2011, net unrealized gains on investments included in Accumulated other comprehensive income (AOCI) were correspondingly reduced by $1,511 million and $722 million.

For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The amortized cost of high credit quality securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reflected in Net investment income on the Consolidated Statements of Operations. Interest income on lower rated securities is determined using the prospective yield method.

The Company's carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the General Partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. Changes in net asset values are accounted for under the equity method and recorded within Net investment income on the Consolidated Statements of Operations.

Mortgage loans are commercial in nature, are carried at unpaid principal balance, net of unamortized fees and any valuation allowance, and are recorded once funded. Mortgage loans are considered to be impaired loans when it is probable that contractual principal and interest payments will not be collected. A valuation allowance is established for impaired loans to the extent that the present value of expected future cash flows discounted at the loan's original effective interest rate is less than the carrying value of the loan. Interest income from mortgage loans is recognized on an accrual basis using the effective yield method. Accrual of income is generally suspended for mortgage loans that are impaired and collection of principal and interest payments is unlikely. Mortgage loans are considered past due when full principal or interest payments have not been received according to contractual terms.

Other invested assets are carried at fair value and include overseas deposits, certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected. Overseas deposits are primarily short-term government securities, agency securities, and corporate bonds held in trusts that are managed by Lloyd's of London (Lloyd's). These funds are required of Lloyd's syndicates to protect policyholders in overseas markets and may be denominated in local currency. Changes in fair value of overseas deposits are reflected in Net investment income on the Consolidated Statements of Operations. Changes in fair value of certain derivative securities and securities containing embedded credit derivatives for which the fair value option was elected are reported in Net realized investment gains (losses) in the Consolidated Statements of Operations.

Short term investments are carried at fair value, with the exception of cash accounts earning interest, which are carried at cost and approximate fair value. Changes in fair value are reported as a component of Other comprehensive income.

Purchases and sales of all securities are recorded on the trade date, except for private placement debt securities, including bank loan participations, which are recorded once funded. Realized investment gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.

Income Taxes

The Company and its eligible subsidiaries (CNA Tax Group) are included in the consolidated federal income tax return of Loews and its eligible subsidiaries. The Company accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized.

Pension and Postretirement Benefits

The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities on the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits and actuarial gains and losses are recognized in the year in which the changes occur through Other comprehensive income. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits, and amortization of actuarial gains and losses are recognized on the Consolidated Statements of Operations.

Stock-Based Compensation

The Company records compensation expense using the fair value method for all awards it grants, modifies, repurchases or cancels primarily on a straight-line basis over the requisite service period, generally four years.

Foreign Currency

Foreign currency translation gains and losses are reflected in Stockholders' equity as a component of Accumulated other comprehensive income. The Company's foreign subsidiaries' balance sheet accounts are translated at the exchange rates in effect at each year end and income statement accounts are either translated at the exchange rate on the date of the transaction or at the average exchange rates. Foreign currency transaction gains (losses) of $12 million, $4 million and $(19) million were included in determining net income (loss) for the years ended December 31, 2012, 2011 and 2010.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is determined principally on the straight-line method. Furniture and fixtures are depreciated over seven years. Office equipment is depreciated over five years. The estimated lives for data processing equipment and software range from three to five years. Leasehold improvements are depreciated over the corresponding lease terms not to exceed the underlying asset life. The Company's owned buildings, and related capital improvements, are depreciated over periods not to exceed fifty years.

Goodwill

Goodwill represents the excess of purchase price over the fair value of the net assets of acquired entities and businesses. Goodwill related to Hardy may change from period to period as a result of foreign currency translation. Goodwill is tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the goodwill recognized as part of the acquisition of Hardy.

Intangible Assets

Intangible assets are reported within Other assets. As of December 31, 2012, the Company's finite-lived intangible assets were $40 million. The Company had no finite-lived intangible assets at December 31, 2011. Finite-lived intangible assets are amortized over their estimated useful lives. As of December 31, 2012, and 2011, the Company's indefinite-lived intangible assets were $73 million and $16 million. Indefinite-lived intangible assets are tested for impairment annually or when certain triggering events require such tests. See Note B to the Consolidated Financial Statements for further discussion of the intangible assets acquired as part of the acquisition of Hardy.

Earnings (Loss) Per Share Data

Earnings (loss) per share attributable to the Company's common stockholders is based on 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 years ended December 31, 2012, 2011, and 2010, approximately 417 thousand, 290 thousand and 380 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 730 thousand, 1.1 million and 1.2 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.

Supplementary Cash Flow Information

Cash payments made for interest were $170 million, $175 million and $145 million for the years ended December 31, 2012, 2011 and 2010. Cash refunds received for income taxes were $29 million and $175 million for the years ended December 31, 2012 and 2010. Cash payments made for income taxes were $61 million for the year ended December 31, 2011.

Accounting Standards Updates

Adopted

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 year ended December 31, 2012, the adoption of the new accounting guidance resulted in a $5 million decrease in Net income attributable to CNA and a $0.02 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 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 and the Company's acquisition of the noncontrolling interest of Surety as discussed above.

The impacts on the Company's Consolidated Statements of Operations for the years ended December 31, 2011 and 2010 were a $2 million increase and no impact in Other net realized investment gains, a $234 million and $219 million decrease in Amortization of deferred acquisition costs, a $242 million and $219 million increase in Other operating expenses, a $4 million and $1 million decrease in Income tax expense, resulting in a $2 million decrease and a $1 million increase in Net income attributable to CNA, and a $0.01 decrease and no impact 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.

Notes to Condensed Financial Information

A. Basis of Presentation

The condensed financial information of CNA Financial Corporation (CNAF or the Parent Company) should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Item 8 of this Form 10-K. CNAF’s subsidiaries are accounted for using the equity method of accounting. Equity in net income of these subsidiaries is presented on the Condensed Statements of Operations as Equity in net income of subsidiaries. Loews owned approximately 90% of the outstanding common stock of CNAF as of December 31, 2012.

B. Commitments, Contingencies and Guarantees

In the normal course of business, CNAF guarantees the indebtedness of certain of its subsidiaries to the debt maturity or payoff, whichever comes first. These guarantees arise in the normal course of business and are given to induce a lender to enter into an agreement with CNAF’s subsidiaries. CNAF would be required to remit prompt and complete payment when due, should the primary obligor default. The maximum potential amount of future payments that CNAF could be required to pay under these guarantees are approximately $10 million at December 31, 2012. The Parent Company does not believe that a payable is likely under these guarantees.

In the course of selling business entities and assets to third parties, CNAF 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 December 31, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $257 million.

In addition, CNAF 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 December 31, 2012, CNAF 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 December 31, 2012, CNAF has no recorded liabilities related to indemnification agreements. The Parent Company does not believe that any indemnity claim payments are likely.

In the normal course of business, CNAF has provided guarantees to holders of structured settlement annuities (SSA) provided by certain of its subsidiaries, which expire through 2120. CNAF would be required to remit SSA payments due to claimants if the primary obligor failed to perform on these contracts. The maximum potential amount of future payments that CNAF could be required to pay under these guarantees are approximately $1.9 billion at December 31, 2012. The Parent Company does not believe that a payable is likely under these guarantees.

Reinsurance Disclosures [Abstract]

Reinsurance

Note I. Reinsurance

The Company cedes insurance to reinsurers to limit its maximum loss, provide greater diversification of risk, minimize exposures on larger risks and to exit certain lines of business. The ceding of insurance does not discharge the primary liability of the Company. A credit exposure exists with respect to property and casualty and life reinsurance ceded to the extent that any reinsurer is unable to meet its obligations or to the extent that the reinsurer disputes the liabilities assumed under reinsurance agreements. Property and casualty reinsurance coverages are tailored to the specific risk characteristics of each product line and the Company's retained amount varies by type of coverage. Reinsurance contracts are purchased to protect specific lines of business such as property and workers' compensation. Corporate catastrophe reinsurance is also purchased for property and workers' compensation exposure. Currently, most reinsurance contracts are purchased on an excess of loss basis. The Company also utilizes facultative reinsurance in certain lines. In addition, the Company assumes reinsurance, primarily through Hardy and as a member of various reinsurance pools and associations.

The following table summarizes the amounts receivable from reinsurers at December 31, 2012 and 2011.

The Company has established an allowance for uncollectible reinsurance receivables. The Company reviews the allowance quarterly and adjusts the allowance as necessary to reflect changes in estimates of uncollected balances. The allowance may also be reduced related to write-offs of reinsurance receivable balances.

The Company attempts to mitigate its credit risk related to reinsurance by entering into reinsurance arrangements with reinsurers that have credit ratings above certain levels, and by obtaining collateral. On a limited basis, the Company may enter into reinsurance agreements with reinsurers that are not rated, primarily captive reinsurers. The primary methods of obtaining collateral are through reinsurance trusts, letters of credit and funds withheld balances. Such collateral was approximately $3.7 billion and $3.6 billion at December 31, 2012 and 2011.

The Company's largest recoverables from a single reinsurer at December 31, 2012, including prepaid reinsurance premiums, were approximately $2.7 billion from subsidiaries of Berkshire Hathaway Group, $900 million from subsidiaries of Swiss Re Group, and $350 million from subsidiaries of the Hartford Insurance Group. The recoverable from the Berkshire Hathaway Group includes amounts related to third party reinsurance for which a subsidiary of Berkshire Hathaway has assumed the credit risk under the terms of the Loss Portfolio Transfer as discussed in Note G.

The effects of reinsurance on earned premiums and written premiums for the years ended December 31, 2012, 2011 and 2010 are shown in the following tables.

On April 19, 2012, the Company 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 the Company's 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, the Company is required to pay a facility fee which would adjust automatically in the event of a change in the Company's 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. As of December 31, 2012, we had no outstanding borrowings under the new credit agreement.

The Company's remaining debt obligations contain customary covenants for investment grade issuers. The Company is in compliance with all covenants as of and for the year ended December 31, 2012.

The combined aggregate maturities for debt at December 31, 2012 are presented in the following table.

Derivative Financial Instruments

Summary of Derivative Instruments [Abstract]

Derivative Financial Instruments

Note D. Derivative Financial Instruments

The Company may use derivatives in the normal course of business, primarily in an attempt to reduce its exposure to market risk (principally interest rate risk, credit risk, equity price risk and foreign currency risk) stemming from various assets and liabilities. The Company's principal objective under such strategies is to achieve the desired reduction in economic risk, even if the position does not receive hedge accounting treatment.

The Company may enter into interest rate swaps, futures and commitments to purchase securities to manage interest rate risk. Credit derivatives such as credit default swaps (CDS) are entered into to modify the credit risk inherent in certain investments. The Company may use foreign currency forward contracts to manage foreign currency risk.

In addition to the derivatives used for risk management purposes described above, the Company may also use derivatives for purposes of income enhancement. Income enhancement transactions are entered into with the intention of providing additional income or yield to a particular portfolio segment or instrument. Income enhancement transactions are limited in scope and primarily involve the sale of covered options in which the Company receives a premium in exchange for selling a call or put option.

Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to the instruments recognized on the Consolidated Balance Sheets. The Company generally requires that all over-the-counter derivative contracts be governed by an International Swaps and Derivatives Association Master Agreement, and exchanges collateral under the terms of these agreements with its derivative investment counterparties depending on the amount of the exposure and the credit rating of the counterparty. The Company does not offset its net derivative positions against the fair value of the collateral provided. The fair value of cash collateral provided by the Company was $1 million at December 31, 2012 and 2011. There was no cash collateral received from counterparties held at December 31, 2012 or 2011.

Derivative securities are recorded at fair value. See Note E for information regarding the fair value of derivative securities. Changes in the fair value of derivatives not associated with the trading portfolio are reported in Net realized investment gains (losses) on the Consolidated Statements of Operations. Changes in the fair value of derivatives associated with the trading portfolio are reported in Net investment income on the Consolidated Statements of Operations.

A summary of the recognized gains (losses) related to derivative financial instruments follows.

Net OTTI losses recognized in earnings	$	154	$	216	$	232

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.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the December 31, 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 December 31, 2012.

The following table summarizes the activity for the years ended December 31, 2012, 2011 and 2010 related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held at December 31, 2012, 2011 and 2010 for which a portion of an OTTI loss was recognized in Other comprehensive income.

Contractual Maturity

The following table summarizes available-for-sale fixed maturity securities by contractual maturity at December 31, 2012 and 2011. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid with or without call or prepayment penalties. Securities not due at a single date are allocated based on weighted average life.

Contractual Maturity

Limited Partnerships

The carrying value of limited partnerships as of December 31, 2012 and 2011 was $2,462 million and $2,245 million, which includes undistributed earnings of $768 million and $560 million. Limited partnerships comprising 67% of the total carrying value are reported on a current basis through December 31, 2012 with no reporting lag, 17% are reported on a one month lag and the remainder are reported on more than a one month lag. As of December 31, 2012 and 2011, the Company had 79 active limited partnership investments. The number of limited partnerships held and the strategies employed provide diversification to the limited partnership portfolio and the overall invested asset portfolio.

Of the limited partnerships held, 80% and 81% at December 31, 2012 and 2011 employ hedge fund strategies that generate returns through investing in securities that are marketable while engaging in various management techniques primarily in public fixed income and equity markets. These hedge fund strategies include both long and short positions in fixed income, equity and derivative instruments. The hedge fund strategies may seek to generate gains from mispriced or undervalued securities, price differentials between securities, distressed investments, sector rotation, or various arbitrage disciplines. Within hedge fund strategies, approximately 48% were equity related, 27% pursued a multi-strategy approach, 22% were focused on distressed investments and 3% were fixed income related at December 31, 2012.

Limited partnerships representing 16% and 14% at December 31, 2012 and 2011 were invested in private debt and equity. The remaining were invested in various other partnerships including real estate. The ten largest limited partnership positions held totaled $1,309 million and $1,218 million as of December 31, 2012 and 2011. Based on the most recent information available regarding the Company’s percentage ownership of the individual limited partnerships, the carrying value reflected on the Consolidated Balance Sheets represents approximately 4% of the aggregate partnership equity at December 31, 2012 and 2011, and the related income reflected on the Consolidated Statements of Operations represents approximately 3%, 4%, and 3% of the changes in partnership equity for all limited partnership investments for the years ended December 31, 2012, 2011 and 2010.

While the Company generally does not invest in highly leveraged partnerships, there are risks which may result in losses due to short-selling, derivatives or other speculative investment practices. The use of leverage increases volatility generated by the underlying investment strategies.

The Company’s limited partnership investments contain withdrawal provisions that generally limit liquidity for a period of thirty days up to one year and in some cases do not permit withdrawals until the termination of the partnership. Typically, withdrawals require advance written notice of up to 90 days.

Commercial Mortgage Loans

Risks related to the recoverability of loan balances include declines in the estimated cash flows from underlying property leases, fair value of collateral and creditworthiness of tenants of credit tenant loan properties, where lease payments directly service the loan. The Company evaluates loans for impairment on a specific loan basis and identifies loans for evaluation of impairment based on the collection experience of each loan and other credit quality indicators such as debt service coverage ratio and the creditworthiness of the borrower or tenants of credit tenant loan properties. As of December 31, 2012 and 2011, there were no loans past due or in non-accrual status, and no valuation allowance was recorded.

Investment Commitments

As of December 31, 2012, the Company had committed approximately $202 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships.

As of December 31, 2012, the Company had mortgage loan commitments of $22 million representing signed loan applications received and accepted.

The Company invests in various privately placed debt securities, including bank loans, as part of its overall investment strategy and has committed to additional future purchases, sales and funding. As of December 31, 2012, the Company had commitments to purchase $185 million and sell $164 million of such investments.

Investments on Deposit

Securities with carrying values of approximately $3.6 billion and $3.5 billion were deposited by the Company’s insurance subsidiaries under requirements of regulatory authorities and others as of December 31, 2012 and 2011.

Cash and securities with carrying values of approximately $4 million and $5 million were deposited with financial institutions as collateral for letters of credit as of December 31, 2012 and 2011. In addition, cash and securities were deposited in trusts with financial institutions to secure reinsurance and other obligations with various third parties. The carrying values of these deposits were approximately $277 million and $288 million as of December 31, 2012 and 2011.

Segment Reporting [Abstract]

Business Segments

Note O. Business Segments

The Company's core property and casualty commercial insurance operations are reported in three business segments: CNA Specialty, CNA Commercial and Hardy. CNA Specialty provides a broad array of professional, financial and specialty property and casualty products and services, primarily through insurance brokers and managing general underwriters. CNA Commercial includes property and casualty coverages sold to small businesses and middle market entities and organizations primarily through an independent agency distribution system. CNA Commercial also includes commercial insurance and risk management products sold to large corporations primarily through insurance brokers. Hardy, a specialized Lloyd's underwriter, underwrites primarily short-tail exposures in marine and aviation, non-marine property, specialty lines and property treaty reinsurance.

The Company's non-core operations are managed in two segments: Life & Group Non-Core and Corporate & Other Non-Core. Life & Group Non-Core primarily includes the results of the life and group lines of business that are in run-off. Corporate & Other Non-Core primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP.

The accounting policies of the segments are the same as those described in Note A. 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, deferred acquisition costs, and goodwill 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.

Approximately 9.2%, 8.8% and 6.9% of the Company's direct written premiums were derived from outside the United States for the years ended December 31, 2012, 2011 and 2010.

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.

Benefit Plans

Note K. Benefit Plans

Pension and Postretirement Health Care Benefit Plans

CNA sponsors noncontributory pension plans, primarily through the CNA Retirement Plan, typically covering full-time employees age 21 and over that have completed at least one year or 1,000 hours of service.

Effective January 1, 2000, the CNA Retirement Plan was closed to new participants. Existing participants at that time were given a choice to either continue to accrue benefits under the CNA Retirement Plan or to cease accruals at December 31, 1999. Employees who chose to continue to accrue benefits under the plan will receive a benefit based on their years of credited service and highest 60 months of compensation at termination. Compensation is defined as regular salary, eligible bonuses and overtime. Employees who elected to cease accruals at December 31, 1999 received the present value of their accrued benefit in an accrued pension account that is credited with interest based on the annual rate of interest on 30-year Treasury securities. These employees also receive certain enhanced employer contributions in the CNA Savings and Capital Accumulation Plan.

CNA's funding policy for defined benefit pension plans is to make contributions in accordance with applicable governmental regulatory requirements with consideration of the funded status of the plans.

CNA provides certain health care benefits to eligible retired employees, their covered dependents and their beneficiaries primarily through the CNA Health and Group Benefits Program. These benefits have largely been eliminated for active employees.

The following table provides a reconciliation of benefit obligations and plan assets for the years ended December 31, 2012 and 2011.

Actuarial assumptions used for the CNA Retirement Plan and CNA Health and Group Benefits Program to determine benefit obligations are set forth in the following table.

Actuarial Assumptions for Benefit Obligations

December 31	2012		2011
Pension benefits
Discount rate	3.800	%	4.600	%
Expected long term rate of return	7.750		8.000
Rate of compensation increases	4.066		4.125
Postretirement benefits
Discount rate	2.800	%	3.750	%

Actuarial assumptions used for the CNA Retirement Plan and CNA Health and Group Benefits Program to determine net cost or benefit are set forth in the following table.

Actuarial Assumptions for Net Cost or Benefit

Years ended December 31	2012		2011		2010
Pension benefits
Discount rate	4.600	%	5.375	%	5.700	%
Expected long term rate of return	8.000		8.000		8.000
Rate of compensation increases	4.125		5.030		5.030
Postretirement benefits
Discount rate	3.750	%	4.375	%	4.875 / 5.500%

In determining the expected long term rate of return on plan assets assumption for the CNA Retirement Plan, CNA considered the historical performance of the benefit plan investment portfolio as well as long term market return expectations based on the investment mix of the portfolio.

The CNA Health and Group Benefits Program has limited its share of the health care trend rate to a cost-of-living adjustment of 4% per year. For all participants, the employer subsidy on health care costs will not increase by more than 4% per year. As a result, the assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation for the CNA Health and Group Benefits Program was 4% per year in 2012, 2011 and 2010.

The health care cost trend rate assumption may have a significant effect on the amount of the benefit obligation and periodic cost reported. An increase in the assumed health care cost trend rate of 1% in each year would have no significant impact on the Company's accumulated postretirement benefit obligation or the Company's aggregate net periodic postretirement benefit for 2012. A decrease in the assumed health care cost trend rate of 1% in each year would decrease the Company's accumulated postretirement benefit obligation as of December 31, 2012 by $3 million and would have no significant impact on the Company's aggregate net periodic postretirement benefit for 2012.

CNA employs a total return approach whereby a mix of equity and fixed maturity securities are used to maximize the long term return of plan assets for a prudent level of risk and to manage cash flows according to plan requirements. The intent of this strategy is to minimize the Company's expense related to funding the plan by outperforming plan liabilities over the long run. Risk tolerance is established after careful consideration of the plan liabilities, plan funded status and corporate financial conditions. The investment portfolio contains a diversified blend of fixed maturity, equity and short term securities. Alternative investments, including limited partnerships, are used to enhance risk adjusted long term returns while improving portfolio diversification. At December 31, 2012 the plan had committed approximately $41 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships. Derivatives may be used to gain market exposure in an efficient and timely manner. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.

Pension plan assets measured at fair value on a recurring basis are summarized below.

The limited partnership investments are recorded at fair value, which represents the plan's share of net asset value of each partnership, as determined by the General Partner. Level 2 includes limited partnership investments which can be redeemed at net asset value in 90 days or less. Level 3 includes limited partnership investments with withdrawal provisions greater than 90 days, or for which withdrawals are not permitted until the termination of the partnership. Within hedge fund strategies, approximately 54% are equity related, 35% pursue a multi-strategy approach and 11% are focused on distressed investments at December 31, 2012.

The fair value of the insurance company guaranteed investment contracts is an estimate of the amount that would be received in an orderly sale to a market participant at the measurement date. The amount the plan would receive from the contract holder if the contracts were terminated is the primary input and is unobservable. The guaranteed investment contracts are therefore classified as Level 3 investments.

For a discussion of the fair value levels and the valuation methodologies used to measure fixed maturity securities, equities, derivatives and short term investments, see Note E.

In 2013, CNA expects to contribute $90 million to its pension plans and $6 million to its postretirement health care benefit plans.

Savings Plans

CNA sponsors savings plans, which are generally contributory plans that allow most employees to contribute a maximum of 20% of their eligible compensation, subject to certain limitations prescribed by the IRS. The Company contributes matching amounts to participants, amounting to 70% of the first 6% (35% of the first 6% in the first year of employment) of eligible compensation contributed by the employee. Employees vest in these contributions ratably over five years.

The CNA Savings and Capital Accumulation Plan allows employees to make contributions to an investment fund that is supported in part by an investment contract purchased from CAC. CAC will not accept any further deposits under this contract. The liability to the CNA Savings and Capital Accumulation Plan is included in Separate account liabilities and Policyholders' funds on the Consolidated Balance Sheets, and was $256 million and $381 million at December 31, 2012 and 2011.

As noted above, during 2000, CCC employees were required to make a choice regarding their continued participation in CNA's defined benefit pension plan. Employees who elected to forgo earning additional benefits in the defined benefit pension plan and all employees hired by CCC on or after January 1, 2000 receive a Company contribution of 3% or 5% of their eligible compensation, depending on their age. In addition, these employees are eligible to receive additional discretionary contributions of up to 2% of eligible compensation and an additional Company match of up to 80% of the first 6% of eligible compensation contributed by the employee. These additional contributions are made at the discretion of management and are contributed to participant accounts in the first quarter of the year following management's determination of the discretionary amounts. Employees vest in these contributions ratably over five years.

Benefit expense for the Company's savings plans was $70 million, $60 million and $61 million for the years ended December 31, 2012, 2011 and 2010.

Stock-Based Compensation

The CNAF Incentive Compensation Plan (the Plan), as amended and restated on January 1, 2010, authorizes the grant of stock-based compensation to certain management personnel for up to 6 million shares of CNAF's common stock. The Plan currently provides for awards of stock options, stock appreciation rights (SARs), restricted shares, performance-based restricted share units (RSUs) and performance share units. The number of shares available for the granting of stock-based compensation under the Plan as of December 31, 2012 was approximately 1.9 million.

The Company recorded stock-based compensation expense related to the Plan of $9 million, $6 million and $5 million for the years ended December 31, 2012, 2011 and 2010. The related income tax benefit recognized was $3 million, $2 million and $2 million. The compensation cost related to nonvested awards not yet recognized was $12 million, and the weighted average period over which it is expected to be recognized is 1.38 years at December 31, 2012.

Equity based compensation that is not fully vested prior to termination is generally forfeited upon termination, except as otherwise provided by contractual obligations. In addition, any such compensation that vested prior to termination is generally canceled immediately, except in cases of retirement, death or disability, and as otherwise provided by contractual obligations.

Stock Options and SARs

The exercise price of all stock options and SARs granted is based on the market value of the Company's common stock as of the date of grant. Stock options and SARs generally vest ratably over a four-year service period following date of grant and have a maximum term of ten years.

The fair value of granted stock options and SARs was estimated at the grant date using the Black-Scholes option-pricing model. The Black-Scholes model incorporates a risk free rate of return and various assumptions regarding the underlying common stock and the expected life of the securities granted. Different interest rates and assumptions were used for each grant, as appropriate based on date of grant.

The following table presents the significant assumptions used to estimate the fair value of granted stock options and SARs for the years ended December 31, 2012, 2011 and 2010.

Years ended December 31	2012		2011		2010

Share Awards

The fair value of share awards is based on the market value of the Company's common stock as of the date of grant. Share awards currently granted under the Plan include restricted shares, performance-based RSUs, and performance share units. Generally, restricted shares vest ratably over a four-year service period following the date of grant. Performance-based RSUs generally become payable within a range of 0% to 100% of the number of shares initially granted based upon the attainment of specific annual performance goals and vest ratably over a four-year service period following the date of grant. Performance share units become payable within a range of 0% to 200% of the number of shares initially granted based upon the attainment of specific performance goals achieved over a three year period.

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 $391 million, $222 million and $121 million for the years ended December 31, 2012, 2011 and 2010. Catastrophe losses in 2012 related primarily to Storm Sandy and other U.S. storms.

The table below provides a reconciliation between beginning and ending claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves of the life company.

A&EP Reserves

On August 31, 2010, Continental Casualty Company (CCC) together with several of the Company’s insurance subsidiaries completed a transaction with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which substantially all of the Company’s legacy A&EP liabilities were ceded to NICO (Loss Portfolio Transfer).

Under the terms of the NICO transaction, effective January 1, 2010 the Company ceded approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $4 billion. Included in the $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves was approximately $90 million of net claim and allocated claim adjustment expense reserves relating to the Company’s discontinued operations. The $1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third party reinsurance contracts. The NICO aggregate reinsurance limit also covers credit risk on the existing third party reinsurance related to these liabilities.

The Company paid NICO a reinsurance premium of $2 billion and transferred to NICO billed third party reinsurance receivables related to A&EP claims with a net book value of $215 million (net of an allowance of $100 million for uncollectible reinsurance receivables on billed third party reinsurance receivables, as discussed further below). As of August 31, 2010, NICO deposited approximately $2.2 billion in a collateral trust account as security for its obligations to the Company. NICO may reduce the collateral by the amount of net A&EP claim and allocated claim adjustment expense payments. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the full aggregate reinsurance limit as well as certain of NICO’s performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third party reinsurers related to the Company’s A&EP claims.

The following table displays the impact of the Loss Portfolio Transfer on the 2010 Consolidated Statement of Operations.

Impact on Consolidated Statement of Operations

Year ended December 31
(In millions)	2010
Other operating expenses	$	529
Income tax benefit	185
Loss from continuing operations, included in the Corporate & Other Non-Core segment	(344		)
Loss from discontinued operations	(21		)
Net loss attributable to CNA	$	(365	)

In connection with the transfer of billed third party reinsurance receivables related to A&EP claims and the coverage of credit risk afforded under the terms of the Loss Portfolio Transfer, the Company reduced its allowance for uncollectible reinsurance receivables on billed third party reinsurance receivables and ceded claim and allocated claim adjustment expense reserves by $200 million. This reduction is reflected in Other operating expenses presented above.

The Loss Portfolio Transfer is considered a retroactive reinsurance contract. In the event that the cumulative claim and allocated claim adjustment expenses ceded under the Loss Portfolio Transfer exceed the consideration paid, the resulting gain from such excess would be deferred. A cumulative amortization adjustment would be recognized in earnings in the period such excess arises so that the resulting deferred gain would reflect the balance that would have existed if the revised estimate was available at the inception date of the Loss Portfolio Transfer. This accounting generally results in a reserve charge because of the timing difference between the recognition of the gross adverse reserve development and the related ceded reinsurance benefit. However, there is no economic impact as long as the additional losses are within the limit under the contract.

The remaining amount available under the $4 billion aggregate limit of the Loss Portfolio Transfer was $2.0 billion on an incurred basis at December 31, 2012. This incurred amount includes $399 million of adverse prior year development since the contract effective date of January 1, 2010. Any future adverse prior year development in excess of approximately $230 million would put the Loss Portfolio Transfer into an overall gain position under retroactive reinsurance accounting. The net ultimate paid losses ceded under the Loss Portfolio Transfer were $661 million through December 31, 2012. The fair value of the collateral trust account at December 31, 2012 was $2.5 billion.

Net Prior Year Development

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. These changes can be favorable or unfavorable. The following tables and discussion include the net prior year development recorded for CNA Specialty, CNA Commercial, Hardy and Corporate & Other Non-Core segments for the years ended December 31, 2012, 2011 and 2010. The net prior year development presented below includes premium development due to its direct relationship to claim and claim adjustment expense reserve development. The net prior year development presented below also includes the impact of commutations and write-offs, but excludes the impact of increases or decreases in the allowance for uncollectible reinsurance. See Note I for further discussion of the provision for uncollectible reinsurance.

Favorable net prior year development of $11 million, $29 million and $2 million was recorded in the Life & Group Non-Core segment for the years ended December 31, 2012, 2011 and 2010.

For the year ended December 31, 2012, favorable premium development was recorded for CNA Commercial primarily due to premium adjustments on auditable policies arising from increased exposures.

For the year ended December 31, 2011, favorable premium development was recorded for CNA Specialty primarily due to changes in estimates of exposures in medical professional liability tail coverages. 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.

For the year ended December 31, 2010, unfavorable premium development for CNA Commercial was recorded due to a change in ultimate premium estimates relating to retrospectively rated policies and return premium on auditable policies due to reduced exposures.

Fair Value Disclosures [Abstract]

Fair Value

Note E. Fair Value

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

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

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

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

Prices may fall within Level 1, 2 or 3 depending upon the methodologies and inputs used to estimate fair value for each specific security. Prices are determined by a dedicated group who ultimately report to the Company's 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 and $72 million of transfers from Level 1 to Level 2during the year ended December 31, 2012. There were no significant transfers between Level 1 and Level 2 during the year ended December 31, 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 and the credit spread adjustment that is security specific. Fair value of certain private placement debt securities is determined using internal models with inputs that are not market observable.

Equity Securities

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

Other Invested Assets

Level 1 securities include exchange traded derivatives, primarily futures, valued using quoted market prices. Level 2 securities include overseas deposits, which can be redeemed at net asset value in 90 days or less, and derivatives, primarily currency forwards valued using observable market forward rates. Over-the-counter derivatives, principally interest rate swaps, total return swaps, credit default swaps, equity warrants and options, are valued using inputs including broker/dealer quotes and are classified within Level 3 of the valuation hierarchy due to a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include 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 Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.

Life Settlement Contracts

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

Separate Account Business

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

Significant Unobservable Inputs

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

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

For fixed maturity securities, an increase to the expected call date assumption and credit spread adjustment 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 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 Consolidated Balance Sheets are listed in the tables below.

December 31, 2012	Carrying Amount		Estimated Fair Value

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 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.

Income Tax Disclosure [Abstract]

Income Taxes

Note F. Income Taxes

The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. Loews and the Company have agreed that for each taxable year, the Company will 1) be paid by Loews the amount, if any, by which the Loews consolidated federal income tax liability is reduced by virtue of the inclusion of the CNA Tax Group in the Loews consolidated federal income tax return, or 2) pay to Loews an amount, if any, equal to the federal income tax that would have been payable by the CNA Tax Group filing a separate consolidated tax return. In the event that Loews should have a net operating loss in the future computed on the basis of filing a separate consolidated tax return without the CNA Tax Group, the Company may be required to repay tax recoveries previously received from Loews. This agreement may be canceled by either party upon 30 days written notice.

For the years ended December 31, 2012, 2011, and 2010 the Company received from Loews $75 million, $10 million, and $298 million related to federal income taxes.

For 2010 through 2012, the IRS has accepted Loews and the Company into the Compliance Assurance Process (CAP), which is a voluntary program for large corporations. Under CAP, the IRS conducts a real-time audit and works contemporaneously with the Company to resolve any issues prior to the filing of the tax return. The Company believes that this approach should reduce tax-related uncertainties, if any.

At December 31, 2012 and 2011, there were no unrecognized tax benefits.

The Company recognizes interest accrued related to: 1) unrecognized tax benefits in Interest expense and 2) tax refund claims in Other revenues on the Consolidated Statements of Operations. The Company recognizes penalties (if any) in Income tax (expense) benefit on the Consolidated Statements of Operations. During 2012, the Company recognized $2 million of interest income and no penalties. During 2011 and 2010, the Company did not recognize any interest or penalties. There were no amounts accrued for interest or penalties at December 31, 2012 or 2011.

The following table provides a reconciliation between the Company's federal income tax (expense) benefit at statutory rates and the recorded income tax (expense) benefit, excluding discontinued operations.

Provision has not been made for the investment in certain subsidiaries for which the Company intends to invest the undistributed earnings indefinitely. At December 31, 2012, the company has not provided deferred taxes of $4 million on $12 million of undistributed earnings related to a foreign subsidiary.

The following table provides the current and deferred components of the Company's income tax (expense) benefit, excluding taxes on discontinued operations.

Total income tax presented above includes foreign tax expense of approximately $34 million, $27 million and $50 million related to income from continuing foreign operations of approximately $88 million, $75 million and $91 million for the years ended December 31, 2012, 2011 and 2010.

The deferred tax effects of the significant components of the Company's deferred tax assets and liabilities are set forth in the table below.

Net unrealized gains	737		513
Other liabilities	57		37
Gross deferred tax liabilities	1,070		791
Net deferred tax asset	$	93	$	415

At December 31, 2012, the CNA Tax Group had loss carryforwards of approximately $9 million which expire in 2014, and tax credit carryforwards of $4 million.

Although realization of deferred tax assets is not assured, management believes it is more likely than not that the recognized net deferred tax asset will be realized through recoupment of ordinary and capital taxes paid in prior carryback years and through future earnings, reversal of existing temporary differences and available tax planning strategies. As a result, no valuation allowance was recorded at December 31, 2012 or 2011.

Stockholders' Equity and Statutory Accounting Practices

Stockholders' Equity and Statutory Accounting Practices [Abstract]

Stockholders' Equity And Statutory Accounting Practices

Note M. Stockholders’ Equity and Statutory Accounting Practices

2008 Senior Preferred

In 2008, the Company issued, and Loews purchased, $1.25 billion of CNAF non-voting cumulative senior preferred stock, which was approved by a special review committee of independent members of CNAF's Board of Directors. As of December 31, 2010, the preferred stock was redeemed in full.

CNAF used the majority of the proceeds from the 2008 Senior Preferred to increase the statutory surplus of its principal insurance subsidiary, CCC, through the purchase of a $1.0 billion surplus note of CCC. Surplus notes are financial instruments with a stated maturity date and scheduled interest payments, issued by insurance enterprises with the approval of the insurer’s domiciliary state. Surplus notes are treated as capital under statutory accounting. All payments of interest and principal on this note are subject to the prior approval of the Illinois Department of Insurance (the Department). The surplus note of CCC had a term of 30 years and accrued interest at a rate of 10% per year. Interest on the note was payable quarterly. In 2012, CCC received regulatory approval from the Department to repay the $250 million outstanding balance of the $1.0 billion surplus note to CNAF.

Common Stock Dividends

Dividends of $0.60 and $0.40 per share on CNA's common stock were declared and paid in 2012 and 2011. No common stock dividends were declared or paid in 2010.

Statutory Accounting Practices

CNAF’s insurance subsidiaries are domiciled in various jurisdictions. These subsidiaries prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions’ insurance regulators. Domestic prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners (NAIC) as well as state laws, regulations and general administrative rules. These statutory accounting principles vary in certain respects from GAAP. In converting from statutory accounting principles to GAAP, the more significant adjustments include deferral of policy acquisition costs and the inclusion of net unrealized holding gains or losses in stockholders’ equity relating to certain fixed maturity securities.

CNAF’s ability to pay dividends and other credit obligations is significantly dependent on receipt of dividends from CCC as it directly or indirectly owns all significant subsidiaries. The payment of dividends by CNAF's insurance subsidiaries without prior approval of the insurance department of each subsidiary’s domiciliary jurisdiction is generally limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective insurance regulator.

Dividends from CCC are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Department, may be paid only from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of December 31, 2012, CCC is in a positive earned surplus position, enabling CCC to pay approximately $550 million of dividend payments during 2013 that would not be subject to the Department’s prior approval. The actual level of dividends paid in any year is determined after an assessment of available dividend capacity, holding company liquidity and cash needs as well as the impact the dividends will have on the statutory surplus of the applicable insurance company.

CNAF’s domestic insurance subsidiaries are subject to risk-based capital requirements. Risk-based capital is a method developed by the NAIC to determine the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of risk-based capital specifies various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. The adequacy of a company's actual capital is evaluated by a comparison to the risk-based capital results, as determined by the formula. Companies below minimum risk-based capital requirements are classified within certain levels, each of which requires specified corrective action. As of December 31, 2012 and 2011, all of CNAF’s domestic insurance subsidiaries exceeded the minimum risk-based capital requirements.

Subsidiaries with insurance operations outside the United States are also subject to insurance regulation in the countries in which they operate. The Company has legal entity and branch operations in other countries, primarily the United Kingdom, Canada and Bermuda. CNAF’s foreign legal entities and branch met or exceeded their respective regulatory and other capital requirements.

Combined statutory capital and surplus and net income (loss), determined in accordance with accounting practices prescribed or permitted by insurance and/or other regulatory authorities for the Combined Continental Casualty Companies and the life company, were as follows.

(b) Information derived from the statutory-basis financial statements to be filed with insurance regulators.

The Hardy insurance entities are not owned by CCC, therefore their regulatory capital is not included in the Statutory Capital and Surplus of the Combined Continental Casualty Companies presented in the table above. At December 31, 2012, Hardy's portion of Syndicate 382's capital requirement was approximately $330 million, which included $66 million of capital provided by CCC and included in Combined Continental Casualty Companies' Statutory Capital and Surplus above.

Related Party Transactions

Note R. Related Party Transactions

The Company reimburses Loews, or pays directly, for management fees, travel and related expenses, software fees, and expenses of investment facilities and services provided to the Company. The amounts reimbursed or paid by the Company were $39 million, $38 million and $38 million for the years ended December 31, 2012, 2011 and 2010. The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. See Note F for a detailed description of the income tax agreement with Loews. In addition, the Company writes, at standard rates, a limited amount of insurance for Loews and its subsidiaries. The earned premiums for the years ended December 31, 2012, 2011 and 2010 were $2 million in each year.

CNA previously sponsored a stock ownership plan whereby the Company financed the purchase of Company common stock by certain former officers, including executive officers. Interest charged on the principal amount of these outstanding stock purchase loans is generally equivalent to the short term applicable federal rate, compounded semi-annually, in effect on the disbursement date of the loan. Loans made pursuant to the plan are generally full recourse and are secured by the stock purchased. The loans were originally issued with a ten-year maturity date, and the majority of the remaining loans have been extended with current terms maturing through August 2015. The carrying value of the loans as of December 31, 2012 approximates the fair value of the related common stock collateral.

Hardy [Abstract]

Hardy

Note B. Hardy

On July 2, 2012, the Company completed the acquisition of all outstanding shares of Hardy, a specialized 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 December 31, 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 year ended December 31, 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:

Operating Leases, Commitments and Contingencies, and Guarantees [Abstract]

Operating Leases, Commitments and Contingencies, and Guarantees

Note L. Operating Leases, Commitments and Contingencies, and Guarantees

Operating Leases

The Company occupies office facilities under lease agreements that expire at various dates. In addition, data processing, office and transportation equipment is leased under agreements that expire at various dates. Most leases contain renewal options that provide for rent increases based on prevailing market conditions. Lease expenses for the years ended December 31, 2012, 2011 and 2010were $52 million, $50 million and $52 million. Sublease revenues for the years ended December 31, 2012, 2011 and 2010 were $2 million, $2 million and $3 million.

The table below presents the future minimum lease payments to be made under non-cancelable operating leases along with future minimum sublease receipts to be received on owned and leased properties at December 31, 2012.

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 December 31, 2012 that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $111 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 $7 million at December 31, 2012, were $2 million in 2013, $2 million in 2014, and $3 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 December 31, 2012, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $725 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 December 31, 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 December 31, 2012 and 2011, the Company had recorded liabilities of approximately $7 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.
