CNA Financial Corporation
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 June 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 June 30, 2021 and for the three and six months ended June 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 six months ended June 30, 2021, approximately 952 thousand and 967 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 1 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 six months ended June 30, 2020, approximately 445 thousand and 778 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 915 thousand and 13 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 six months ended June 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 June 30, 2021 and December 31, 2020, the net unrealized gains on investments included in AOCI were correspondingly reduced by Shadow Adjustments of $ 2,635 million and $ 2,773 million.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the June 30, 2021 securities in a gross unrealized loss position table above are not indicative of the ultimate collectibility 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 June 30, 2021.

Actual maturities may differ from contractual maturities because certain securities may be called or prepaid. Securities not due at a single date are allocated based on weighted average life.
Derivative Financial Instruments
The Company holds an embedded derivative on a funds withheld liability with a notional value of $ 274 million and $ 190 million and a fair value of $( 13 ) million an d $( 19 ) million as of June 30, 2021 and December 31, 2020. The embedded derivative on the funds withheld liability is accounted for separately and reported with the funds withheld liability in Other liabilities on the Condensed Consolidated Balance Sheets.
Investment Commitments
As part of its overall investment strategy, the Company invests in various assets which require future purchase, sale or funding commitments. These investments are recorded once funded, and the related commitments may include future capital calls from various third-party limited partnerships, signed and accepted mortgage loan applications, and obligations related to private placement securities. As of June 30, 2021, the Company had commitments to purchase or fund approximately $ 1,330 million and sell approximately $ 95 million under the terms of these investments.

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.

Assets and Liabilities Measured at Fair Value
Assets and liabilities measured at fair value on a recurring basis are presented in the following tables. Corporate bonds and other includes obligations of the U.S. Treasury, government-sponsored enterprises, foreign governments and redeemable preferred stock.

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.
21
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 June 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.
22
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.
June 30, 2021 Estimated Fair Value
(In millions) 		Valuation Technique(s) Unobservable Input(s) Range
(Weighted Average)
Fixed maturity securities $ 1,067 Discounted cash flow Credit spread
1 % - 8 % ( 2 %)

(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.

These assets and liabilities are not listed in the tables above.
23
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 our results of operations and/or equity. The Company reported catastrophe losses, net of reinsurance, of $ 54 million and $ 179 million for the three and six months ended June 30, 2021 related primarily to severe weather related events. The Company reported catastrophe losses, net of reinsurance, of $ 301 million and $ 376 million for the three and six months ended June 30, 2020. Net catastrophe losses for the three months ended June 30, 2020 included $ 182 million related to the COVID-19 pandemic, $ 61 million related to civil unrest and $ 58 million related primarily to severe weather related events. Net catastrophe losses for the six months ended June 30, 2020 included $ 195 million related to the COVID-19 pandemic, $ 61 million related to civil unrest, and $ 120 million related primarily to severe weather related events.

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 $ 12 million and $ 20 million for the three months ended June 30, 2021 and 2020 and $ 22 million and $ 34 million for the six months ended June 30, 2021 and 2020. As of June 30, 2021 and December 31, 2020, the cumulative amounts ceded under the LPT were $ 3.3 billion. The unrecognized deferred retroactive reinsurance benefit was $ 376 million and $ 398 million as of June 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 June 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 June 30, 2021, the cumulative amounts ceded under the EWC LPT were $ 690 million and the remaining amount available under the $ 1 billion aggregate limit was $ 310 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.

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.
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.
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 June 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.


42
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.

CATASTROPHES AND RELATED REINSURANCE
Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil unrest, cyber attacks, pandemics and acts of terrorism that produce unusually large aggregate losses.
Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in our results of operations and/or equity. We generally seek to manage our exposure to catastrophes through the purchase of catastrophe reinsurance and have catastrophe reinsurance treaties that cover property and workers’ compensation losses. We conduct an ongoing review of our risk and catastrophe coverages and from time to time make changes as we deem appropriate. We utilize various reinsurance programs to mitigate catastrophe losses including excess-of-loss occurrence and aggregate treaties covering property and workers’ compensation, and the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA), as well as individual risk agreements that reinsure from losses from specific classes or lines of business. During the second quarter of 2021, we added a quota share treaty to our property reinsurance program, which covers policies written during the treaty term and in-force as of June 1, 2021. As a result of the coverage of in-force policies, net written premiums were reduced by $122 million during the quarter for the one-time catch-up under the treaty of unearned premium on policies previously written as of the June 1, 2021 treaty inception. This ceded premium will earn in future quarters consistent with the underlying gross policies. We also renewed our excess-of-loss property catastrophe reinsurance as described below.
Group North American Property Treaty
We purchased corporate catastrophe excess-of-loss treaty reinsurance covering our U.S. states and territories and Canadian property exposures underwritten in our North American and European companies. Exposures underwritten through Hardy are excluded. The treaty has a term of June 1, 2021 to June 1, 2022 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $190 million up to $900 million for all losses other than earthquakes. Earthquakes are covered up to $1.0 billion. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological or chemical attack. All layers of the treaty provide for one full reinstatement.
See the Catastrophes and Related Reinsurance 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 $242 million for the three months ended June 30, 2021 as compared with the same period in 2020. Core income for our Property & Casualty Operations increased $226 million primarily due to lower net catastrophe losses and improved non-catastrophe current accident year underwriting results. Core income for our Life & Group segment increased $29 million while core loss for our Corporate & Other segment increased $13 million.
Net catastrophe losses were $54 million and $301 million for the three months ended June 30, 2021 and 2020. Catastrophe losses for the three months ended June 30, 2021 related primarily to severe weather related events. Catastrophe losses for the three months ended June 30, 2020 include $182 million related to COVID-19, $61 million related to civil unrest and $58 million related primarily to severe weather related events.

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. As a result, our written premium production, most notably in Commercial, was impacted by lower levels of retention and new business during the three months ended June 30, 2021. We have also incurred additional expenses within our Corporate Segment related to the cybersecurity attack and expect these expenses may continue. 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.

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.

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 six months ended June 30, 2021, net cash provided by operating activities was $685 million as compared with $650 million for the same period in 2020. The increase in cash provided by operating activities was driven by lower net claim payments and an increase in premiums collected, largely offset by the payment of the EWC LPT premium. 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 $202 million for the six months ended June 30, 2021, as compared with net cash provided of $475 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 six months ended June 30, 2021, net cash used by financing activities was $441 million as compared with $776 million for the same period in 2020. Financing activities for the periods presented include:
• During the six months ended June 30, 2021, we paid dividends of $414 million and repurchased 377,615 shares of our common stock at an aggregate cost of $18 million.
• During the six months ended June 30, 2020, we paid dividends of $750 million and repurchased 435,376 shares of our common stock at an aggregate cost of $18 million.
Common Stock Dividends
Cash dividends of $1.51 per share on our common stock, including a special cash dividend of $0.75 per share, were declared and paid during the six months ended June 30, 2021. On July 30, 2021, our Board of Directors declared a quarterly cash dividend of $0.38 per share, payable September 2, 2021 to stockholders of record on August 16, 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.
59
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 June 30, 2021, CCC was in a positive earned surplus position. CCC paid dividends of $480 million and $815 million during the six months ended June 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 transaction in which, subject to certain limitations, we ceded our legacy A&EP liabilities will not fully perform their obligations to CNA, the uncertainty in estimating loss reserves for A&EP liabilities and the possible continued exposure of CNA to liabilities for A&EP claims that are not covered under the terms of the transaction;
• the performance of reinsurance companies under reinsurance contracts with us; and
• the risks and uncertainties associated with potential acquisitions and divestitures, including the consummation of such transactions, the successful integration of acquired operations and the potential for subsequent impairment of goodwill or intangible assets.
Industry and General Market Factors
• the 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
61
• 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 six months ended June 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 June 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 June 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 June 30, 2021 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. Other Information
Item 1. Legal Proceedings
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 the quarter ended March 31, 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 March 31, 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 and processing and paying claims and other obligations.
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. 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.

64

Any significant breach in our data security infrastructure 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.
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. Any such breach of our 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), it is possible losses may exceed the amount available under our coverage and/or our coverage policy may not 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 replenishment of the Company’s current policy through the end of the term, as well as future cybersecurity insurance coverage beyond the current term, may be difficult to obtain and will likely only be available at significantly higher cost.
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.
