Notes to Condensed Consolidated Financial Statements

Note A. General

Basis of Presentation

The Condensed 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 89.6 % of the outstanding common stock of CNAF as of September 30, 2021.

The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, including certain financial statement notes, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in CNAF's Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2020, including the summary of significant accounting policies in Note A. The preparation of Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The interim financial data as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020 is unaudited. However, in the opinion of management, the interim data includes all adjustments, including normal recurring adjustments, necessary for a fair statement of the Company's results for the interim periods. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

Accounting Standards Pending Adoption

In August 2018, the FASB issued ASU 2018-12, Financial Services-Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts . The updated accounting guidance requires changes to the measurement and disclosure of long-duration contracts. The guidance requires entities to annually update cash flow assumptions, including morbidity and persistency, and update discount rate assumptions quarterly using an upper-medium grade fixed-income instrument yield. The effect of changes in cash flow assumptions will be recorded in the Company's results of operations and the effect of changes in discount rate assumptions will be recorded in Other comprehensive income. This guidance is effective for interim and annual periods beginning after December 15, 2022, with early adoption permitted. The guidance may be applied using either a modified retrospective transition method or a full retrospective transition method. The guidance requires restatement of prior periods presented. The Company plans to adopt on the effective date, using the modified retrospective transition method and is currently evaluating the effect the updated guidance will have on its financial statements, including the increased disclosure requirements. The annual updating of cash flow assumptions is expected to increase income statement volatility. While the requirements of the new guidance represent a material change from existing GAAP, the underlying economics of the business and related cash flows will be unchanged.

Note B. Earnings (Loss) Per Share

Earnings (loss) per share 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) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

For the three and nine months ended September 30, 2021, approximately 1,015 thousand and 980 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 4 thousand and 3 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.

For the three and nine months ended September 30, 2020, approximately 620 thousand and 730 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 9 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.

The Company repurchased 377,615 and 435,376 shares of CNAF common stock at an aggregate cost of $ 18 million during each of the nine months ended September 30, 2021 and 2020.

The net unrealized gains on investments included in the tables above are recorded as a component of Accumulated other comprehensive income (AOCI). When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. To the extent that unrealized gains on fixed income securities supporting certain products within the Life & Group segment would result in a premium deficiency if realized, a related increase in Insurance reserves is recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (loss) (Shadow Adjustments). As of September 30, 2021 and December 31, 2020, the net unrealized gains on investments included in AOCI were correspondingly reduced by Shadow Adjustments of $ 2,481 million and $ 2,773 million.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2021 securities in a gross unrealized loss position table above are not indicative of the ultimate collectability of the current amortized cost of the securities, but rather are attributable to changes in interest rates, credit spreads and other factors. The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional impairment losses to be recorded as of September 30, 2021.

Note D. Fair Value

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

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

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

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

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

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

Securities may be transferred in or out of levels within the fair value hierarchy based on the availability of observable market information and quoted prices used to determine the fair value of the security. The availability of observable market information and quoted prices varies based on market conditions and trading volume.

Table of Contents

Valuation Methodologies and Inputs

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

Fixed Maturity Securities

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

Short Term and Other Invested Assets

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

As of September 30, 2021 and December 31, 2020, there were $ 65 million and $ 71 million of overseas deposits within Other invested assets, which can be redeemed at net asset value in 90 days or less. Overseas deposits are excluded from the fair value hierarchy because their fair value is recorded using the net asset value per share (or equivalent) practical expedient.

Derivative Financial Investments

The embedded derivative on funds withheld liability is valued using the change in fair value of the assets supporting the funds withheld liability, which are fixed maturity securities primarily valued with observable inputs.

Table of Contents

Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurements of Level 3 assets. Valuations for assets and liabilities not presented in the tables 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. The weighted average rate is calculated based on fair value.

September 30, 2021	Estimated Fair Value (In millions)	Valuation Technique(s)	Unobservable Input(s)	Range (Weighted Average)
Fixed maturity securities	$ 1,154	Discounted cash flow	Credit spread	1 % - 7 % ( 2 %)

December 31, 2020	Estimated Fair Value (In millions)	Valuation Technique(s)	Unobservable Input(s)	Range (Weighted Average)
Fixed maturity securities	$ 966	Discounted cash flow	Credit spread	1 % - 8 % ( 3 %)

For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement.

Financial Assets and Liabilities Not Measured at Fair Value

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

September 30, 2021 — (In millions)	Carrying Amount	Estimated Fair Value — Level 1	Level 2	Level 3	Total
Assets
Mortgage loans	$ 1,031	$ —	$ —	$ 1,106	$ 1,106
Liabilities
Long term debt	$ 2,778	$ —	$ 3,027	$ —	$ 3,027

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

Note E. Claim and Claim Adjustment Expense Reserves

Property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to historical patterns such as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and 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 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 $ 178 million and $ 357 million for the three and nine months ended September 30, 2021. Catastrophe losses for the three months ended September 30, 2021 included $ 114 million for Hurricane Ida. Catastrophe losses for the nine months ended September 30, 2021 were driven by severe weather related events, primarily Hurricane Ida and Winter Storms Uri and Viola. The Company reported catastrophe losses, net of reinsurance, of $ 160 million and $ 536 million for the three and nine months ended September 30, 2020. Net catastrophe losses for the three months ended September 30, 2020 were driven by severe weather related events, primarily Hurricanes Laura, Isaias and Sally, and the Midwest derecho. Net catastrophe losses for the nine months ended September 30, 2020 included $ 273 million related primarily to severe weather related events, $ 195 million related to the COVID-19 pandemic and $ 68 million related to civil unrest.

Asbestos & Environmental Pollution (A&EP) Reserves

In 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 through a Loss Portfolio Transfer (LPT). At the effective date of the transaction, 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. 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 LPT 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, resulting in total consideration of $ 2.2 billion.

In years subsequent to the effective date of the LPT, the Company recognized adverse prior year development on its A&EP reserves resulting in additional amounts ceded under the LPT. As a result, the cumulative amounts ceded under the LPT have exceeded the $ 2.2 billion consideration paid, resulting in the NICO LPT moving into a gain position, requiring retroactive reinsurance accounting. Under retroactive reinsurance accounting, this gain is deferred and only recognized in earnings in proportion to actual paid recoveries under the LPT. Over the life of the contract, there is no economic impact as long as any additional losses incurred are within the limit of the LPT. In a period in which the Company recognizes a change in the estimate of A&EP reserves that increases or decreases the amounts ceded under the LPT, the proportion of actual paid recoveries to total ceded losses is affected and the change in the deferred gain is recognized in earnings as if the revised estimate of ceded losses was available at the effective date of the LPT. The effect of the deferred retroactive reinsurance benefit is recorded in Insurance claims and policyholders' benefits on the Condensed Consolidated Statements of Operations.

The impact of the LPT on the Condensed Consolidated Statements of Operations was the recognition of a retroactive reinsurance benefit of $ 8 million and $ 9 million for the three months ended September 30, 2021 and 2020 and $ 30 million and $ 43 million for the nine months ended September 30, 2021 and 2020. As of September 30, 2021 and December 31, 2020, the cumulative amounts ceded under the LPT were $ 3.3 billion. The unrecognized deferred retroactive reinsurance benefit was $ 368 million and $ 398 million as of September 30, 2021 and December 31, 2020 and is included within Other liabilities on the Condensed Consolidated Balance Sheets.

NICO established a collateral trust account as security for its obligations to the Company. The fair value of the collateral trust account was $ 2.9 billion as of September 30, 2021. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the 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 majority of the Company’s A&EP claims.

Excess Workers' Compensation LPT

On February 5, 2021, CCC completed a transaction with Cavello Bay Reinsurance Limited (Cavello), a subsidiary of Enstar Group Limited, under which certain legacy excess workers’ compensation (EWC) liabilities were ceded to Cavello. Under the terms of the transaction, based on reserves in place as of January 1, 2020, the Company ceded approximately $ 690 million of net EWC claim and allocated claim adjustment expense reserves to Cavello under an LPT with an aggregate limit of $ 1 billion. The Company paid Cavello a reinsurance premium of $ 697 million, less claims paid between January 1, 2020 and the closing date of the agreement of $ 64 million. After transaction costs, the Company recognized an after-tax loss of approximately $ 12 million in the Corporate & Other segment in the first quarter of 2021 related to the EWC LPT.

As of September 30, 2021, the cumulative amount ceded under the EWC LPT was $ 690 million.

Cavello established a collateral trust account as security for its obligations to the Company, which will be maintained at 105 % of outstanding reserves.

Credit Risk for Ceded Reserves

The majority of the Company’s outstanding voluntary reinsurance receivables are due from reinsurers with financial strength ratings of A- or higher. Receivables due from reinsurers with lower financial strength ratings are primarily due from captive reinsurers and are backed by collateral arrangements.

Life & Group Policyholder Reserves

The Company’s Life & Group segment includes its run-off long term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long term care policies provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and the Company has the ability to increase policy premiums, subject to state regulatory approval.

The Company maintains both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for the Life & Group segment. Claim and claim adjustment expense reserves consist of estimated reserves for long term care policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported. In developing the claim and claim adjustment expense reserve estimates for long term care policies, the Company’s actuaries perform a detailed claim reserve review on an annual basis. The review analyzes the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. In addition, claim and claim adjustment expense reserves are also maintained for the structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for structured settlement obligations, the Company's actuaries review mortality experience on an annual basis. The Company’s recorded claim and claim adjustment expense reserves reflect management's best estimate after incorporating the results of the most recent reviews.

The Company completed its annual claim reserve reviews in the third quarters of 2021 and 2020 resulting in $ 40 million and $ 37 million pretax reductions in long term care reserves primarily due to lower claim severity than anticipated in the reserve estimates and $ 2 million and $ 46 million pretax increases in the structured settlement claim reserves primarily due to lower discount rate assumptions and mortality assumption changes.

Future policy benefit reserves consist of active life reserves related to the Company’s long term care policies for policyholders that are not currently receiving benefits and represent the present value of expected future benefit payments and expenses less expected future premium. The determination of these reserves requires management to make estimates and 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 that management believes are subject to the most variability are morbidity, persistency, discount rates and anticipated future premium rate increases. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Discount rates are influenced by the investment yield on assets supporting long term care reserves which is subject to interest rate and market volatility and may also be affected by changes to the Internal Revenue Code. Future premium rate increases are generally subject to regulatory approval, and therefore the exact timing and size of the approved rate increases are unknown. As a result of this variability, the Company’s long term care reserves may be subject to material increases if actual experience develops adversely to the Company’s expectations.

Annually, in the third quarter, management assesses the adequacy of its long term care future policy benefit reserves by performing a gross premium valuation (GPV) to determine if there is a premium deficiency. Under the GPV, management estimates required reserves using best estimate assumptions as of the date of the assessment without provisions for adverse deviation. The GPV required reserves are then compared to the existing recorded reserves. If the GPV required reserves are greater than the existing recorded reserves, the existing assumptions are unlocked and future policy benefit reserves are increased to the greater amount. Any such increase is reflected in the Company’s results of operations in the period in which the need for such adjustment is determined. If the GPV required reserves are less than the existing recorded reserves, assumptions remain locked in and no adjustment is required.

The GPV for the long term care future policy benefit reserves, performed in the third quarter of 2021, indicated recorded reserves included a pretax margin of approximately $ 72 million as of September 30, 2021.

Table of Contents

The GPV for the long term care future policy benefit reserves, performed in the third quarter of 2020, indicated a premium deficiency primarily driven by lower discount rate assumptions. Recognition of the premium deficiency resulted in a $ 74 million pretax increase in policyholders' benefits reflected in the Company's results of operations for the three and nine months ended September 30, 2020.

Note F . Legal Proceedings, Contingencies and Guarantees

The Company is a party to various claims and litigation incidental to its business, which, based on the facts and circumstances currently known, are not material to the Company's results of operations or financial position.

Data Breach-related Contingency

As previously disclosed, the Company sustained a sophisticated cybersecurity attack in March 2021 involving ransomware. The Company’s investigation revealed that an unauthorized third party copied some personal information relating to certain current and former employees, contractor workers and their dependents and certain other persons, including some policyholders. In July 2021, we provided notifications to the impacted individuals and to regulators, in accordance with applicable law. The Company may be subject to subsequent investigations, fines or penalties, as well as other legal claims and actions, related to the foregoing. The likelihood is reasonably possible, but the amount of such fines, penalties or costs, if any, cannot be estimated at this time.

Guarantees

The Company has provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities issued by a previously owned subsidiary. As of September 30, 2021, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $ 1.6 billion, which will be paid over the lifetime of the annuitants. The Company does not believe any payment is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

Note I. Business Segments

The Company's property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International. These three segments are collectively referred to as Property & Casualty Operations. The Company's operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other.

Effective January 1, 2021, and in connection with the ceding of certain legacy reserves under a retroactive reinsurance agreement executed in February 2021, management changed the segment presentation of a legacy portfolio of excess workers’ compensation policies relating to business written in 2007 and prior. This business, which was previously reported as part of the Commercial business segment, is now reported as part of the Corporate & Other business segment. Further information on this retroactive reinsurance agreement is provided in Note E. In addition, a determination was made to change the segment presentation of certain legacy mass tort reserves. Similar to the aforementioned excess workers’ compensation legacy business, these legacy mass tort reserves were previously reported in the Commercial business segment and are now reported as part of the Corporate & Other business segment. These changes were made to better reflect the manner in which the Company is organized for purposes of making operating decisions and assessing performance. Prior period information has been conformed to the new segment presentation.

The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2020. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs, Goodwill and Deferred non-insurance warranty acquisition expense and revenue are readily identifiable for individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Net investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense have been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.

In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio.

The performance of the Company's insurance operations is monitored by management through core income (loss), which is derived from certain income statement amounts. 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.

Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses and any cumulative effects of changes in accounting guidance. The calculation of core income (loss) excludes net investment gains or losses because net investment gains or losses are generally driven by economic factors that are not necessarily reflective of our primary operations.

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

OVERVIEW

The following discussion highlights significant factors affecting the Company. References to “we,” “our,” “us” or like terms refer to the business of CNA.

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements included under Part I, Item 1 of this Form 10-Q, as well as the updates and additions to our Risk Factors disclosed under Part II, Item 1A of this Form 10-Q. The following discussion should also be read in conjunction with Item 1A Risk Factors and Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2020.

We utilize the core income (loss) financial measure to monitor our operations. Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses and any cumulative effects of changes in accounting guidance. The calculation of core income (loss) excludes net investment gains or losses because net investment gains or losses are generally driven by economic factors that are not necessarily reflective of our primary operations. Management monitors core income (loss) for each business segment to assess segment performance. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure. See further discussion regarding how we manage our business in Note I to the Condensed Consolidated Financial Statements included under Part I, Item 1. For reconciliations of non-GAAP measures to the most comparable GAAP measures and other information, please refer herein and/or to CNA's most recent Annual Report on Form 10-K on file with the Securities and Exchange Commission.

In evaluating the results of our Specialty, Commercial and International segments, we utilize the loss ratio, the loss ratio excluding catastrophes and development, the expense ratio, the dividend ratio, the combined ratio and the combined ratio excluding catastrophes and development. 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 loss ratio excluding catastrophes and development excludes net catastrophes losses and changes in estimates of claim and claim adjustment expense reserves, net of reinsurance, for prior years from the loss ratio. 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. The combined ratio excluding catastrophes and development is the sum of the loss ratio excluding catastrophes and development, the expense ratio and the dividend ratio. In addition we also utilize renewal premium change, rate, retention and new business in evaluating operating trends. Renewal premium change represents the estimated change in average premium on policies that renew, including rate and exposure changes. Rate represents the average change in price on policies that renew excluding exposure change. For certain products within Small Business, where quantifiable, rate includes the influence of new business as well. Exposure represents the measure of risk used in the pricing of the insurance product. Retention represents the percentage of premium dollars renewed in comparison to the expiring premium dollars from policies available to renew. Renewal premium change, rate and retention presented for the prior year are updated to reflect subsequent activity on policies written in the period. New business represents premiums from policies written with new customers and additional policies written with existing customers. Gross written premiums, excluding third party captives, excludes business which is ceded to third party captives, including business related to large warranty programs.

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

CRITICAL ACCOUNTING ESTIMATES

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

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

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

• Insurance Reserves

• Long Term Care Reserves

• Reinsurance and Insurance Receivables

• Valuation of Investments and Impairment of Securities

• Income Taxes

Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from our estimates and may have a material adverse impact on our results of operations, financial condition, equity, business, and insurer financial strength and corporate debt ratings. See the Critical Accounting Estimates section of our Management's Discussion and Analysis of Financial Condition and Results of Operations included under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020 for further information.

Three Month Comparison

Core income increased $44 million for the three months ended September 30, 2021 as compared with the same period in 2020. Core income for our Property & Casualty Operations decreased $19 million primarily due to higher net catastrophe losses and lower net investment income partially offset by improved non-catastrophe current accident year underwriting results. Core results for our Life & Group segment improved $76 million while core loss for our Corporate & Other segment increased $13 million.

Net catastrophe losses were $178 million and $160 million for the three months ended September 30, 2021 and 2020. Catastrophe losses for the three months ended September 30, 2021 included $114 million for Hurricane Ida.

Nine Month Comparison

Core income increased $441 million for the nine months ended September 30, 2021 as compared with the same period in 2020. Core income for our Property & Casualty Operations increased $349 million primarily due to improved current accident year underwriting results and higher net investment income driven by limited partnership and common stock returns. Core results for our Life & Group segment improved $137 million while core loss for our Corporate & Other segment increased $45 million.

Net catastrophe losses were $357 million and $536 million for nine months ended September 30, 2021 and 2020.

SEGMENT RESULTS

The following discusses the results of operations for our business segments. Our property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International, which we refer to collectively as Property & Casualty Operations. Our operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other.

Effective January 1, 2021, we changed the segment presentation of a legacy portfolio of excess workers’ compensation policies and certain legacy mass tort reserves. These businesses were previously reported in the Commercial business segment and are now reported as part of the Corporate & Other business segment. Prior period information has been conformed to the new segment presentation. See Note I to the Condensed Consolidated Financial Statements included under Part I, Item 1 for more information on the changes to our business segments.

Recent Developments

As previously disclosed, we sustained a sophisticated cybersecurity attack in March 2021 involving ransomware that caused a network disruption and impacted certain of our systems. We have incurred expenses within our Corporate Segment related to the cybersecurity attack and expect these expenses will continue. Additionally, we anticipate making continued investments in technology to improve our security and infrastructure, which will increase our expenses in future periods. While we do not believe that the March 2021 cybersecurity attack will have a material impact on our business, results of operations or financial condition, no assurances can be given at this time as we continue to assess the full impact from the incident, including costs, expenses and insurance coverage.

Net written premiums for Commercial decreased $81 million for the nine months ended September 30, 2021 as compared with the same period in 2020 driven by the impact of the June 1, 2021 written premium catch-up resulting from the addition of the quota share treaty to our property reinsurance program. Excluding the impact of the June 1, 2021 written

premium catch-up, net written premiums increased $31 million for the nine months ended September 30, 2021 as compared with the same period in 2020. Net earned premiums for Commercial increased $159 million for the nine months ended September 30, 2021 as compared with the same period in 2020. The increase in net earned premiums was partially impacted by a reduction in estimated audit premiums related to COVID-19 in 2020.

Core income increased $120 million for the nine months ended September 30, 2021 as compared with the same period in 2020 primarily due to higher net investment income driven by limited partnership and common stock returns and improved current accident year underwriting results.

The combined ratio of 106.0% improved 2.3 points for the nine months ended September 30, 2021 as compared with the same period in 2020 primarily due to a 1.8 point improvement in the expense ratio. The improvement in the expense ratio was primarily due to higher net earned premiums and a favorable acquisition ratio. Net catastrophe losses were $332 million, or 12.6 points of the loss ratio, for the nine months ended September 30, 2021, as compared with $354 million, or 14.3 points of the loss ratio, for the nine months ended September 30, 2020.

Unfavorable net prior year loss reserve development of $2 million was recorded for the nine months ended September 30, 2021 as compared with favorable net prior year loss reserve development of $8 million for the nine months ended September 30, 2020. Further information on net prior year loss reserve development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Three Month Comparison

Core results improved $76 million for the three months ended September 30, 2021 as compared with the same period in 2020.

Life & Group results for the three months ended September 30, 2021 included no unlocking event for active life reserves as a result of the gross premium valuation (GPV). Core income for the three months ended September 30, 2021 included a $31 million favorable impact from the reduction in long term care claim reserves resulting from the annual claim reserve reviews in the third quarter of 2021. Core loss for the three months ended September 30, 2020 included a $59 million charge related to the recognition of an active life reserve premium deficiency for long term care policies. The results for the three months ended September 30, 2020 also included a $36 million charge related to the increase in the structured settlement claim reserves partially offset by a $30 million impact from the reduction in long term care claim reserves, both resulting from the annual claim reserve reviews in the third quarter of 2020.

Nine Month Comparison

Results for the nine months ended September 30, 2021 were generally consistent with the three month summary above.

Life & Group Policyholder Reserves

Annually, in the third quarter, management assesses the adequacy of its long term care future policy benefit reserves by performing a GPV to determine if there is a premium deficiency. See Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1 for further information on the reserving process.

Table of Contents

The September 30, 2021 GPV indicated that our recorded reserves included a margin of approximately $72 million. A summary of the changes in the estimated reserve margin is presented in the table below:

Long Term Care Active Life Reserve - Change in estimated reserve margin (In millions)
September 30, 2020 Estimated Margin	$ —
Changes in underlying discount rate assumptions (1)	65
Changes in underlying morbidity assumptions	205
Changes in underlying persistency assumptions	(233)
Changes in underlying premium rate action assumptions	27
Changes in underlying expense and other assumptions	8
September 30, 2021 Estimated Margin	$ 72

(1) Including cost of care inflation assumption.

The increase in the margin in 2021 was primarily driven by changes in discount rate assumptions due to higher near-term expected reinvestment rates and favorable changes to underlying morbidity assumptions. These favorable drivers were partially offset by unfavorable changes to underlying persistency assumptions.

The Company has determined that additional future policy benefit reserves for profits followed by losses are not currently required based on the most recent projection.

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our active life reserve assumptions. The annual GPV process involves updating all assumptions to management's then current best estimate, and historically all significant assumptions have been revised each year. In the table below, we have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group and would occur absent any changes, mitigating or otherwise, in the other assumptions. 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. Any required increase in the recorded reserves resulting from a hypothetical revision in the table below would first reduce the margin in our carried reserves before it would affect results from operations. Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized below. The estimated impacts to results of operations in the table below are after consideration of the existing margin.

Duration

A primary objective in the management of the investment portfolio is to optimize return relative to the 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 as well as domestic and global economic conditions, are some of the factors that enter into an investment decision. We also continually monitor exposure to issuers of securities held and broader industry sector exposures and may from time to time adjust such exposures based on our views of a specific issuer or industry sector.

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

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

(In millions)	September 30, 2021 — Estimated Fair Value	Effective Duration (In years)	December 31, 2020 — Estimated Fair Value	Effective Duration (In years)
Investments supporting Life & Group	$ 18,431	9.3	$ 18,518	9.2
Other investments	28,520	5.1	28,839	4.5
Total	$ 46,951	6.7	$ 47,357	6.3

The investment portfolio is periodically analyzed for changes in duration and related price risk. Certain securities have duration characteristics that are variable based on market interest rates, credit spreads and other factors that may drive variability in the amount and timing of cash flows. Additionally, we periodically review the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes. A summary of these risks and specific analysis on changes is included in the Quantitative and Qualitative Disclosures About Market Risk included under Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2020.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

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

For the nine months ended September 30, 2021, net cash provided by operating activities was $1,354 million as compared with $1,408 million for the same period in 2020. The decrease in cash provided by operating activities was driven by the payment of the EWC LPT premium, increased ceded premiums paid and higher taxes paid, partially offset by an increase in gross premiums collected, lower claim payments and a higher level of distributions from limited partnerships. The EWC LPT is further discussed in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Cash flows from investing activities include the purchase and disposition of financial instruments, excluding those held as trading, and may include the purchase and sale of businesses, equipment and other assets not generally held for resale.

Net cash used by investing activities was $597 million for the nine months ended September 30, 2021, as compared with $407 million for the same period in 2020. Net cash used or provided by investing activities is primarily driven by cash available from operations and other factors, such as financing activities.

Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, and outflows for stockholder dividends, repayment of debt and purchases of treasury stock.

For the nine months ended September 30, 2021, net cash used by financing activities was $545 million as compared with $801 million for the same period in 2020. Financing activities for the periods presented include:

• During the nine months ended September 30, 2021, we paid dividends of $518 million and repurchased 377,615 shares of our common stock at an aggregate cost of $18 million.

• During the nine months ended September 30, 2020, we paid dividends of $850 million and repurchased 435,376 shares of our common stock at an aggregate cost of $18 million.

• In the third quarter of 2020, we issued $500 million of 2.05% senior notes due August 15, 2030 and redeemed the $400 million outstanding aggregate principal balances of our 5.750% senior notes due August 15, 2021.

Common Stock Dividends

Cash dividends of $1.89 per share on our common stock, including a special cash dividend of $0.75 per share, were declared and paid during the nine months ended September 30, 2021. On October 29, 2021, our Board of Directors declared a quarterly cash dividend of $0.38 per share, payable December 2, 2021 to stockholders of record on November 15, 2021. 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.

Table of Contents

Liquidity

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

Dividends from Continental Casualty Company (CCC) are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Illinois Department of Insurance (the Department), are determined based on the greater of the prior year's statutory net income or 10% of statutory surplus as of the end of the prior year, as well as timing and amount of dividends paid in the preceding twelve months. Additionally, ordinary dividends may only be paid from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of September 30, 2021, CCC was in a positive earned surplus position. CCC paid dividends of $600 million and $855 million during the nine months ended September 30, 2021 and 2020. 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.

We have an effective automatic shelf registration statement on file with the Securities and Exchange Commission under which we may publicly issue debt, equity or hybrid securities from time to time.

ACCOUNTING STANDARDS UPDATE

For a discussion of Accounting Standards Updates, see Note A to the Condensed Consolidated Financial Statements included under Part 1, Item 1.

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 (note that loss reserves for long term care, A&EP and other mass tort claims 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; 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 as well as those risks contained in the Risk Factors section of our 2020 Annual Report on Form 10-K and this report:

Company-Specific Factors

• the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of our 2020 Annual Report on Form 10-K and 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 transactions in which, subject to certain limitations, we ceded our legacy A&EP and EWC liabilities, respectively, will not fully perform their respective obligations to CNA, the uncertainty in estimating loss reserves for A&EP and EWC liabilities and the possible continued exposure of CNA to liabilities for A&EP and EWC claims that are not covered under the terms of the respective transactions;

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

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

Industry and General Market Factors

• the COVID-19 pandemic, and actions seeking to mitigate the spread of the virus, have resulted in significant risk across our enterprise; economic uncertainty and depressed business conditions brought on by the crisis may materially and adversely impact our business operations and may lead to increased claim and litigation activity and unfavorable regulatory outcomes.

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

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

• general economic and business conditions, including recessionary conditions that may decrease the size and number of our insurance customers and create losses to our lines of business 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 uncertainty and instability in these markets, as well as the overall economy, and their impact on the returns, types, liquidity and valuation of our investments;

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

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

Regulatory and Legal Factors

• regulatory and legal initiatives and compliance with governmental regulations and other legal requirements, including with respect to cyber security protocols (which may be enhanced following completion of work relating to the sophisticated cyber incident sustained by the Company in March 2021 as discussed in Risk Factors, Part II, Item 1A of this report), legal inquiries by state authorities, judicial interpretations within the regulatory framework, including interpretation of policy provisions, decisions regarding coverage and theories of liability, legislative actions that increase claimant activity, including those revising applicability of statutes of limitations, trends in litigation and the outcome of any litigation involving us and rulings and changes in tax laws and regulations;

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

• 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; and

• regulatory and legal implications relating to the sophisticated cyber incident sustained by the Company in March 2021 that may arise.

Impact of Natural and Man-Made Disasters and Mass Tort Claims

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

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

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

• the occurrence of epidemics and pandemics; and

• mass tort claims, including those related to exposure to potentially harmful products or substances such as glyphosate, lead paint and opioids; and claims arising from changes that repeal or weaken tort reforms, such as those related to abuse reviver statutes.

Our forward-looking statements speak only as of the date of the filing of this Quarterly Report on Form 10-Q and we do not undertake any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date of the statement, even if our expectations or any related events or circumstances change.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There were no material changes in our market risk components for the nine months ended September 30, 2021. See the Quantitative and Qualitative Disclosures About Market Risk included in Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2020 for further information. Additional information related to portfolio duration is discussed in the Investments section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part I, Item 2.

Item 4. Controls and Procedures

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

As of September 30, 2021, the Company's management, including the Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective as of September 30, 2021.

There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2021 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Information on our legal proceedings is set forth in Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Item 1A. Risk Factors

Our Annual Report on Form 10-K for the year ended December 31, 2020 and our Quarterly Report on Form 10-Q for each of the first two quarters of 2021, include detailed discussions of certain material risk factors facing us. The information presented below describes updates and additions to and should be read in conjunction with the risk factors and information disclosed in our Form 10-K and restates in their entirety the risk factors contained in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2021.

Any significant interruption in the operation of our business functions, facilities and systems or our vendors' facilities and systems 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, processing and paying claims and other obligations and issuing financial statements.

Our, or our vendors’, facilities and systems could become unavailable, inoperable, or otherwise impaired from a variety of causes, including 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 cyberattacks, riots, hazardous material releases, medical epidemics or pandemics, utility outages, interruptions of our data processing and storage systems or the systems of third-party vendors, or unavailability of communications facilities. An interruption of our system availability occurred in March 2021 as a result of a cybersecurity attack sustained by the Company. Please refer to the immediately following risk factor for further information regarding this incident. Likewise, we could experience a significant failure, interruption or corruption of one or more of our or our vendors’ information technology, telecommunications, or other systems for various reasons, including significant failures or interruptions that might occur as existing systems are replaced or upgraded. The shut-down or unavailability of one or more of our or our vendors' systems or facilities for these and other reasons 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, including the ability to issue financial statements in a timely manner.

The foregoing risks could also expose us to monetary and reputational damages. Potential exposures resulting from the March 2021 cybersecurity attack, described in the immediately following risk factor, as well as any future incidents may include substantially increased compliance costs, as well as increased costs relating to investments in computer system and security-related upgrades, with those costs potentially not recoverable under relevant insurance coverage. The Company anticipates making continued investments to improve its security and infrastructure. These expenses are not recoverable under relevant insurance coverage. If our business continuity plans or system security do not sufficiently address these risks, they could have a material adverse effect on our business, results of operations and financial condition.

Based on the information currently known, we do not believe that the March 2021 cybersecurity attack will have a material impact on our business, results of operations or financial condition, but no assurances can be given as we continue to assess the full impact from the incident, including costs, expenses and insurance coverage. We may also be subject to future incidents that could have a material adverse effect on our business, results of operations or financial condition or may result in operational impairments and financial losses, as well as significant harm to our reputation.

Any significant breach in our data security infrastructure or our vendors’ facilities and systems could disrupt business, cause financial losses and damage our reputation, and insurance coverage may not be available for claims related to a breach.

A significant breach of our data security infrastructure may result from actions by our employees, vendors, third-party administrators, or unknown third parties or through cyber-attacks. The risk of a breach can exist whether software services are in our data centers or we use cloud-based software services. Breaches have occurred, and may occur again, in our systems and in the systems of our vendors and third party administrators.

Such a breach could affect our data framework or cause a failure to protect the personal information of our customers, claimants or employees, or sensitive and confidential information regarding our business and may result in operational impairments and financial losses, as well as significant harm to our reputation. The breach of confidential information also could give rise to legal liability and regulatory action under data protection and privacy laws, as well as evolving regulation in this regard. During the third quarter of 2021, we were notified of a breach of certain systems of a third-party administrator, which resulted in breach notifications sent by such administrator to potentially impacted persons, including a limited number of Company claimants. While we do not believe such notifications and resultant actions will have a material adverse effect on our business, this or similar incidents, or any other such breach of our or our vendors’ data security infrastructure could have a material adverse effect on our business, results of operations and financial condition.

We sustained a sophisticated cybersecurity attack in March 2021 involving ransomware that caused a network disruption and impacted certain of our systems. Upon detection, we undertook steps to address the incident, including engaging a team of third-party forensic experts and notifying law enforcement and key regulators. We restored network systems and resumed normal operations. We are continuing to assess all actions that we will take to improve our existing systems.

Our investigation revealed that an unauthorized third party copied some personal information relating to certain current and former employees, contractor workers and their dependents and certain other persons, including some policyholders. In July 2021, we provided notifications to the impacted individuals and to regulators, in accordance with applicable law. Although we currently have no indication that the impacted data has been misused, or that CNA or its policyholder data was specifically targeted by the unauthorized third party, we may be subject to subsequent investigations, claims or actions in addition to other costs, fines, penalties, or other obligations related to impacted data, whether or not such data is misused. In addition, the misuse, or perceived misuse, of sensitive or confidential information regarding our business or policyholders could cause harm to our reputation and result in the loss of business with existing or potential customers, which could adversely impact our business, results of operations and financial condition.

Although we maintain cybersecurity insurance coverage insuring against costs resulting from cyber-attacks (including the March 2021 attack), we do not expect the amount available under our coverage and/or our coverage policy to cover all losses. Costs and expenses incurred and likely to be incurred by the Company in connection with the March 2021 attack include both direct and indirect costs and not all may be covered by our insurance coverage. In addition, potential disputes with our insurers about the availability of insurance coverage for claims relating to the March 2021 attack or any future incident could occur. Further, both as a result of the March 2021 attack and industry trends generally, the Company will incur higher costs for the replenishment of the Company’s current policy through the end of the term, as well as future cybersecurity insurance coverage beyond the current term.
