Notes to Condensed Consolidated Financial Statements (Unaudited)
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%89.5% of the outstanding common stock of CNAF as of September 30, 2020.March 31, 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, 2019,2020, 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, 2020March 31, 2021 and for the three and nine months ended September 30,March 31, 2021 and 2020 and 2019 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.
Recently Adopted Accounting Standards Updates (ASU)
ASU 2016-13: In June 2016 the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The updated accounting guidance requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through the Company’s results of operations. For financial assets measured at cost, the expected credit loss model requires immediate recognition of estimated credit losses over the life of the asset and presentation of the asset at the net amount expected to be collected. This new guidance applies to mortgage loan investments, reinsurance and insurance receivables and other financing receivables. For available-for-sale fixed maturity securities carried at fair value, estimated credit losses will continue to be measured at the present value of expected cash flows, however, the other than temporary impairment (OTTI) concept has been eliminated. Under the previous guidance, estimated credit impairments resulted in a write-down of amortized cost. Under the new guidance, estimated credit losses are recognized through an allowance and reversals of the allowance are permitted if the estimate of credit losses declines. For available-for-sale fixed maturity securities where the Company has an intent to sell, impairment will continue to result in a write-down of amortized cost.
On January 1, 2020, the Company adopted the updated guidance using a modified retrospective method with a cumulative effect adjustment recorded to beginning Retained earnings. Prior period amounts have not been adjusted and continue to be reported in accordance with the previous accounting guidance. A prospective transition approach is required for available-for-sale fixed maturity securities that were purchased with credit deterioration (PCD assets) or have recognized an OTTI write-down prior to the effective date. The cumulative effect of the accounting change resulted in a $5 million decrease in Retained earnings, with a corresponding $7 million allowance for credit losses recorded for Mortgage loans partially offset by a $2 million tax impact.

The allowance for uncollectible insurance and reinsurance receivables was unchanged as a result of adopting the new guidance. At adoption, an allowance for credit losses of $6 million was established for available-for-sale fixed maturity securities that were PCD assets, with a corresponding increase to amortized cost, resulting in no adjustment to the carrying value of the securities. Below is a summary of the significant accounting policies impacted by the adoption of ASU 2016-13.
The allowance for credit losses is a valuation account that is reported as a reduction of a financial asset’s cost basis and is measured on a pool basis when similar risk characteristics exist. Management estimates the allowance using relevant available information from both internal and external sources. Historical credit loss experience provides the basis for the estimation of expected credit losses and adjustments may be made to reflect current conditions and reasonable and supportable forecasts. Adjustments to historical loss information are made for any additional factors that come to the Company’s attention. This could include significant shifts in counterparty financial strength ratings, aging of past due receivables, amounts sent to collection agencies, or other underlying portfolio changes. Amounts are considered past due when payments have not been received according to contractual terms. The Company also considers current and forecast economic conditions, using a variety of economic metrics and forecast indices. The sensitivity of expected credit losses relative to changes to these forecast economic conditions can vary by financial asset class. The Company considers a reasonable and supportable forecast period to be up to 24 months from the balance sheet date. After the forecast period, the Company reverts to historical credit experience. The Company uses collateral arrangements such as letters of credit and amounts held in beneficiary trusts to mitigate credit risk, which are considered in the estimate of net amount expected to be collected.
The Company has made a policy election to present accrued interest balances separately from the amortized cost basis of assets and has elected the practical expedient to exclude the accrued interest from the tabular disclosures for mortgage loans and available-for-sale securities. The Company has elected not to estimate an allowance for credit losses on accrued interest receivable. The accrual of interest income is discontinued and the asset is placed on nonaccrual status within 90 days of the interest becoming delinquent. Interest accrued but not received for assets on nonaccrual status is reversed through investment income. Interest received for assets that are on nonaccrual status is recognized as payment is received. The asset is returned to accrual status when the principal and interest amounts contractually due are brought current and future payments are expected. Interest receivable is presented as a component of accrued investment income on the Condensed Consolidated Balance Sheet.
See Note C and Note K to the Condensed Consolidated Financial Statements for additional information regarding credit losses.
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 DurationLong-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, 2021, however the FASB has approved a one year deferral of the effective date. Early2022, with early adoption is permitted. The Companyguidance may elect to apply the guidancebe 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, 2020,March 31, 2021, approximately 620 thousand and 7301,020 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 thosethe same periods, 9period, approximately 120 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, 2019,March 31, 2020, approximately 1 million and 9201,015 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were included inexcluded from the calculation of diluted earnings per share. For those same periods, less than 1 thousand and approximately 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 earningsloss per share because the effect would have been antidilutive.antidilutive due to the net loss position of the Company.

For available-for-sale fixed maturity securities, a credit loss exists if the present value of cash flows expected to be collected is less than the amortized cost basis. The allowance for credit loss related to available-for-sale fixed maturity securities is the difference between present value of cash flows expected to be collected and the amortized cost basis, limited by the amount that the fair value is less than the amortized cost basis. The Company considers all available evidence when determining whether an investment requires a credit loss write-down or allowance to be recorded. Examples of such evidence may include the financial condition and near term prospects of the issuer, whether the issuer is current with interest and principal payments, credit ratings on the security or changes in ratings

over time, general market conditions and industry, sector or other specific factors and whether it is likely that the Company will recover its amortized cost through the collection of cash flows. Changes in the allowance since acquisition are presented as a component of Net investment gains (losses) on the Condensed Consolidated Statements of Operations.
The following tables present the activity related to the allowance on available-for-sale securities with credit impairments and PCDpurchased credit-deteriorated (PCD) assets. Accrued interest receivable on available-for-sale fixed maturity securities totaled $390$389 million, $371 million and $390 million as of March 31, 2021, December 31, 2020 and March 31, 2020 and is excluded from the estimate of expected credit losses and the amortized cost basis in the tables included within this Note.

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, 2020March 31, 2021 and December 31, 2019,2020, the net unrealized gains on investments included in AOCI were correspondingly reduced by Shadow Adjustments of $2,559$2,301 million and $2,198$2,773 million.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2020March 31, 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 September 30, 2020.March 31, 2021.

Mortgage Loans
The allowance for expected credit losses is developed by assessing the credit quality of pools of mortgage loans in good standing using debt service coverage ratios (DSCR) and loan-to-value ratios (LTV). The DSCR compares a property’s net operating income to its debt service payments, including principal and interest. The LTV ratio compares the current unpaid principal balance of the loan to the estimated fair value of the underlying property collateralizing the loan. The pools developed to measure the credit loss allowance use increments of DSCR and LTV to draw distinctions between risk levels. Changes in the allowance for mortgage loans are presented as a component of Net investment gains (losses) on the Condensed Consolidated Statements of Operations.

The following table presents the amortized cost basis of mortgage loans for each credit quality indicator by year of origination. The primary credit quality indicators utilized are debt service coverage ratios (DSCR) and loan-to-value ratios (LTV).

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, 2020March 31, 2021 and December 31, 2019,2020, there were $64$72 million and $60$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.

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 $160$125 million and $536$75 million for the three and nine months ended September 30,March 31, 2021 and 2020. Net catastrophe losses for the three months ended September 30, 2020March 31, 2021 were primarily driven by severe weather related events, primarily Hurricanes Laura, IsaiasWinter Storms Uri and Sally, and the Midwest derecho.Viola. Net catastrophe losses for the ninethree months ended September 30,March 31, 2020 included $273 million related primarily to severe weather related events, $195$13 million related to the COVID-19 pandemic, and $68with the remaining $62 million related to civil unrest. The Company reported catastrophe losses, net of reinsurance, of $32 million and $128 million for the three and nine months ended September 30, 2019 related primarily to U.S. weather related events.

Asbestos and& 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 inon 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 $9$10 million and $7$14 million for the three months ended September 30, 2020March 31, 2021 and 2019 and $43 million for the nine months ended September 30, 2020 and 2019.2020. As of September 30, 2020March 31, 2021 and December 31, 2019,2020, the cumulative amounts ceded under the LPT were $3.2$3.3 billion. The unrecognized deferred retroactive reinsurance benefit was $349$388 million and $392$398 million as of September 30, 2020March 31, 2021 and December 31, 20192020 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 $3.5$4.6 billion and $3.7$4.2 billion as of September 30, 2020March 31, 2021 and December 31, 2019.2020. 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 Policyholder Reserves
The Company’s Life & Group segment includes its run-off long term care businessLimited, 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 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 andof January 1, 2020, the Company has the ability to increase policy premiums, subject to state regulatory approval.
The Company maintains bothceded approximately $690 million of net EWC claim and allocated claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefitsto 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 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 experience study on an annual basis. The study reviews 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 monitor 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 studies.
The Company's most recent annual claim experience studies were completed in the third quarter of 2020 and resulted in a $46 million pretax increase in claim and claim adjustment expense reserve estimates for structured settlement obligations primarily due to lower discount rate assumptions and mortality assumption changes and a $37 million pretax reduction in claim and claim adjustment expense reserves for long term care policies primarily due to lower claim severity than anticipated in the reserve estimates. The Company's 2019 annual claim experience studies were completed in the third quarter of 2019 and resulted in a $56 million pretax reduction in claim and claim adjustment expense reserves for long term care policies primarily due to lower claim severity than anticipated in the reserve estimates.
Future policy benefit reserves represent the active life reservesthree months ended March 31, 2021 related to the Company’s long term care policiesEWC LPT.
Cavello established a collateral trust account as security for policyholders that are not currently receiving benefits,its obligations to the Company, which representwill be maintained at 105% of outstanding reserves. As of March 31, 2021, 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 overremaining amount available under the life$1 billion aggregate limit of the contract. Since many of these contracts may be in forceEWC LPT was $310 million on an incurred basis.

Credit Risk for several decades, these assumptions are subject to significant estimation risk.Ceded Reserves
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 sizemajority of the approved rate increasesCompany’s outstanding voluntary reinsurance receivables are unknown. As a resultdue from reinsurers with financial strength ratings of this variability, the Company’s long term care future policy benefit reserves may be subject to material increases if actual experience develops adversely to the Company’s expectations.A- or higher. Receivables due from reinsurers with lower financial strength ratings are primarily due from captive reinsurers and are backed by collateral arrangements.
Annually, in the third quarter, management assesses the adequacy
26

Table 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. Periodically, management engages independent third parties to assess the appropriateness of its best estimate assumptions. The most recent third party assessment, performed in 2019, validated the assumption setting process and confirmed the best estimate assumptions appropriately reflected the experience data at that time.Contents

The GPV for the long term care future policy benefit reserves, performed in the third quarter of 2020 and 2019, indicated a premium deficiency primarily driven by lower discount rate assumptions. Recognition of the premium deficiency resulted in a $74 million and a $216 million pretax increase in policyholders' benefits reflected in the Company's results of operations for the three and nine months ended September 30, 2020 and 2019.

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.
Guarantees
As of September 30, 2020March 31, 2021 and December 31, 2019,2020, the Company had recorded liabilities of approximately $5 million related to guarantee and indemnification agreements. Management does not believe that any future indemnity claims will be significantly greater than the amounts recorded.
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, 2020,March 31, 2021, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $1.7$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 3 business segments: Specialty, Commercial and International. These 3 segments are collectively referred to as Property & Casualty Operations. The Company's operations outside of Property & Casualty Operations are managed and reported in 2two 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, 2019.2020. 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.

Note K. Expected Credit Losses - Uncollectible Reinsurance and Insurance Receivables
The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. For assessing expected credit losses, the Company separates reinsurance receivables into two pools: voluntary reinsurance receivables and involuntary reinsurance exposures to mandatory pools. The Company has not recorded an allowance for involuntary pools as there is no perceived credit risk. The principal credit quality indicator used in the valuation of the allowance on voluntary reinsurance receivables is the financial strength rating of the reinsurer sourced from major rating agencies. If the reinsurer is unrated, an internal financial strength rating is assigned based on the Company’s historical loss experience and the Company’s assessment of reinsurance counterparty risk profile, which generally corresponds with a B rating. Changes in the allowance are presented as a component of Insurance claims and policyholders' benefits on the Condensed Consolidated Statements of Operations.
The following table summarizes the outstanding amount of voluntary reinsurance receivables, gross of any collateral arrangements, by financial strength rating.

Refer to Note E for information regarding the LPT. The Company has also excluded receivables from involuntary pools.

Voluntary reinsurance receivables within the B- to B++ rating distribution are primarily due from captive reinsurers and backed by collateral arrangements.
The Company has established an allowance for uncollectible insurance receivables. A loss rate methodology is used to determine expected credit losses for premium receivables. This methodology uses the Company’s historical annual credit losses relative to gross premium written to develop a rangeTable of credit loss rates for each dollar of gross written premium underwritten. The expected credit loss for loss sensitive business in good standing is calculated on a pool basis, using historical default rate data obtained from major rating agencies. Changes in the allowance are presented as a component of Other operating expenses on the Condensed Consolidated Statements of Operations.Contents

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 supplemental risk factor regarding the COVID-19 pandemicupdates 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, 2019.2020.
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, 20192020 for further information.

CONSOLIDATED OPERATIONS
Results of Operations
In March 2020,The following table includes the World Health Organization declared COVID-19 to be a pandemic. The pandemic, together with global, national, regional and local efforts to mitigate the spread of the virus, have rapidly evolved and led to severely depressed economic conditions and financial market disruption. While these conditions have had a significant impact across our enterprise during 2020, COVID-19 impacts to ourconsolidated results for the three months ended September 30, 2020 were more limited. During the first quarter of 2020 we experienced significant declines in the value of our investment portfolio, and during the second quarter of 2020 we recorded significant underwriting losses. Whileoperations including our financial markets have broadly recovered during the second and third quarters of 2020, our Net investmentmeasure, core income and Net investment gains (losses) are lower for the nine months ended September 30, 2020 as compared with the same period in 2019.
For a further discussion of COVID-19 impacts on our underwriting results see the Expected impact of COVID-19 on underwriting results within the Segment Results section of this MD&A.

Net catastrophe losses were $536 million and $128 million for the nine months ended September 30, 2020 and 2019. Catastrophe losses for the nine months ended September 30, 2020 include $273 million related primarily to severe weather related events, $195 million related to COVID-19 and $68 million related to civil unrest. The COVID-19 losses, which were recognized in the first half of 2020, followed a detailed review and analysis of existing and potential exposures in light of current information, and represent the Company's best estimate of its ultimate insurance losses and loss adjustment expenses, including defense costs resulting from the pandemic and the consequent economic crisis. The losses were substantially driven by healthcare professional liability with additional impacts from workers' compensation, management liability, commercial property, trade credit and surety. Due to the timing and fluidity of the events, emergence pattern of claims and long tail nature of certain exposures the losses are substantially classified as incurred but not reported (IBNR) reserves. The COVID-19 catastrophe losses do not include the benefits of lower current accident year losses associated with lower loss frequency in certain lines of business as a result of shelter in place restrictions. Those benefits are modest and are partially offset by the impact of a reduction in our estimated audit premiums and an increase in our credit allowance for premiums receivables resulting from the depressed economic conditions.
Favorable net prior year loss reserve development of $8 million and $29 million was recorded for the nine months ended September 30, 2020 and 2019 related to our Specialty, Commercial, International and Corporate & Other segments. 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.

SEGMENT RESULTS
Expected impact of COVID-19 on Property & Casualty underwriting results
Our underwriting results for the first nine months of 2020 were negatively impacted by COVID-19 and the related depressed economic conditions. In many geographic locations, the virus continues to spread. Accordingly, it remains the case that months past the initial identification of the threat, all of the direct and indirect consequences and implications of COVID-19 are not yet known and may not emerge for some time. Until the virus is brought under control, the timing of any economic recovery remains uncertain. As a result, the impact to our results in the first three quarters of 2020 may not be indicative of its impacts for the remainder of 2020 or thereafter. For further discussion of the risks to our business associated with COVID-19 and measures to mitigate the spread of the virus, see the Investments and Liquidity and Capital Resources sections of this MD&A and the Risk Factor included under Part II, Item 1A of this Form 10-Q.
We experienced year-over-year growth in gross and net written premiums, excluding third party captives, driven by rate increases across property and casualty lines of business. However, depressed economic conditions generally have had an unfavorable impact on premium exposures, resulting in a decrease in our estimated audit premiums during the second quarter of 2020 and causing an unfavorable impact on our net earned premiums. Additionally, in the second quarter of 2020 we renewed multiple property and casualty reinsurance treaties at higher costs as well as purchased additional coverage, which had an unfavorable impact on net written premiums and will have an unfavorable impact on our net earned premiums in future quarters. Lower net earned premiums have had and may continue to have an unfavorable impact on our expense ratio. Our expense ratio has also been unfavorably impacted by increases in our allowance for uncollectible insurance receivables, more than offset by lower travel-related expenses. If general economic conditions do not improve in the remainder of 2020 or thereafter, our net written premiums, net earned premiums and our expense ratio may continue to be unfavorably impacted as a result.
While our losses incurred during the first nine months of 2020 related to COVID-19 represent our best estimate of ultimate insurance losses resulting from events occurring in the first nine months of 2020 due to the pandemic and the consequent economic crisis, given the unprecedented nature of this event, a high level of uncertainty exists as to the potential impact on insurance losses from these events or other events that might occur for the remainder of the year and thereafter. The scope, duration and magnitude of the direct and indirect effects could continue to evolve through the remainder of 2020, and possibly thereafter, and could materially impact our ultimate loss estimate, including in lines of business where losses have already been incurred as well as the potential for impacts in other lines unknown at this time. Continued spread of the virus, as well as new or extended shelter in place restrictions and business closures, could cause us to experience additional COVID-19 related catastrophe losses in future quarters.
We have also experienced modest benefits in certain lines of business as a result of lower loss frequency from shelter in place restrictions. Those benefits only apply to a portion of our portfolio, as our larger portfolios, including healthcare, construction and property coverages, have seen limited benefit. In addition, the impact from lower frequency is mostly offset by higher severity in certain areas of the portfolio.
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.

Core lossincome improved $87$32 million for the three months ended September 30, 2020March 31, 2021 as compared with the same period in 2019. 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 primarily driven by actions taken on discount rate assumptions. The normative risk free rate (the projection of the 10-year U.S. Treasury rate in the long term) was lowered by 100 basis points to 2.75% and the time period to grade up to the normative rate was extended from 6 years to 10 years. Core loss for the three months ended September 30, 2020 also included a $36 million increase in the structured settlement claim reserves and a $30 million reduction in long term care claim reserves, both resulting from the annual claim experience studies in the third quarter of 2020. Excluding the impacts of the GPV and claim reserve reviews, core results were favorable driven by better than expected morbidity in the long term care business. Duringbusiness and higher net investment income. The increase in net investment income was driven by returns in the thirdlimited partnership portfolio. Further, during the first quarter of 2020,2021, relative to expectations, we experienced lower new claim frequency, higher claim terminations and more favorable claim severity in the long term care business amid the effects of COVID-19. Given the uncertainty of these trends, we increased our IBNR reserves in anticipation of increased claim activity as the COVID-19 pandemic abates.
Core loss for the three months ended September 30, 2019 included a $170 million charge related to the recognition of an active life reserve premium deficiency partially offset by a $44 million reduction in long term care claim reserves resulting from the annual claim experience study in the third quarter of 2019.
Nine Month Comparison
Core loss improved $88 million for the nine months ended September 30, 2020 as compared with the same period in 2019. The drivers of core loss for the nine month period were generally consistent with the three month summary noted 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.










The September 30, 2020 GPV indicated a premium deficiency of $74 million and future policy benefit reserves were increased accordingly. As a result, the long term care active life reserves carried as of September 30, 2020 represent management's best estimate assumptions at that date with no margin for adverse deviation. A summary of the changes in the GPV results is presented in the table below:
Long Term Care Active Life Reserve - Change in estimated reserve margin (In millions) 
September 30, 2019 Estimated Margin$
Changes in underlying discount rate assumptions(609)
Changes in underlying morbidity assumptions51
Changes in underlying persistency assumptions152
Changes in underlying premium rate action assumptions318
Changes in underlying expense and other assumptions14
September 30, 2020 Premium Deficiency$(74)
The premium deficiency was primarily driven by changes in discount rate assumptions due to lower expected reinvestment rates, contemplating both near-term market indications and long-term normative assumptions. This unfavorable driver was significantly offset by higher than previously estimated rate increases on active rate increase programs, new planned rate increase filings and favorable changes to the underlying persistency and morbidity assumptions.
Our projections do not indicate a pattern of expected profits in earlier future years followed by expected losses in later future years. As such, we will not establish additional future policy benefit reserves for profits followed by losses in periods where the long term care business generates core income. The need for these additional future policy benefit reserves will be re-evaluated in connection with the next GPV, which is expected to be completed in the third quarter of 2021.
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 Hypothetical revisions 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 actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized below.

INVESTMENTS
The financial market disruption in the first quarter of 2020 significantly impacted our investment portfolio. Losses from our limited partnership and common and preferred equity portfolios, as well as the recognition of impairment losses on certain fixed maturity holdings, negatively impacted our Net income for the three months ended March 31, 2020. While financial markets have broadly recovered during the second and third quarters of 2020, there could be continued volatility in our investment portfolio.

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, 2019.2020.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our primary operating cash flow sources are premiums and investment income from our insurance subsidiaries.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.
Related to the COVID-19 pandemic and efforts to mitigate the spread of the virus, as the situation continues to evolve through the remainder of 2020, and possibly thereafter, uncertainty exists as to the potential impacts on our operating cash flows. At this time, we do not believe these impacts would give rise to a material liquidity concern given our overall liquid assets and anticipated future cash flows.
For the ninethree months ended September 30, 2020,March 31, 2021, net cash provided by operating activities was $1,408$82 million as compared with $980$212 million for the same period in 2019.2020. The increasedecrease in cash provided by operating activities was driven by an increase in premiums collected,the payment of the EWC LPT premium partially offset by lower net claim payments and lower income taxes paid, partially offset by a lower level of distributions from limited partnerships.an increase in premiums collected. 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 usedprovided by investing activities was $407$408 million for the ninethree months ended September 30, 2020,March 31, 2021, as compared with $60$1,087 million for the same period in 2019.

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 ninethree months ended September 30, 2020,March 31, 2021, net cash used by financing activities was $801$321 million as compared with $887$675 million for the same period 2019. Financing activities forin 2020. In the periods presented include:

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. In addition, we held $5.5 billion of cash, short term investments and highly liquid securities issued by the U.S. government and its agencies as of September 30, 2020, of which $517 million was held at the CNAF holding company. 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 CCCContinental 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, 2020,March 31, 2021, CCC was in a positive earned surplus position. CCC paid dividends of $855$330 million and $940$670 million during the ninethree months ended September 30, 2020March 31, 2021 and 2019.2020. 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, adopted in the current period and that will be adopted in the future, see Note A to the Condensed Consolidated Financial Statements included under Part I,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:following as well as those risks contained in the Risk Factors section of our 2020 Annual Report on Form 10-K and this report:

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

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 additional losses to our lines of business especially those that provide management and professional liability insurance, as well as surety bonds, to businesses engaged in real estate, financial services and professional services and inflationary pressures on medical care costs, construction costs and other economic sectors that increase the severity of claims;
conditions in the capital and credit markets, including 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

Referendum on the United Kingdom's Membership in the European Union
in 2016, the U.K. approved an exit from the E.U., commonly referred to as "Brexit.” While the withdrawal of the U.K. from the E.U. was official as of January 31, 2020, until the transition period ends, there remains a lack of specificity and detail regarding the long term relationship between the two sides and how businesses operating in both jurisdictions may be affected. In any event, effective January 1, 2019, our E.U. business is no longer handled out of our U.K.-domiciled subsidiary, but through our European subsidiary in Luxembourg, which was established specifically to address the departure of the U.K. from the E.U. and to seek to ensure the Company’s ability to operate effectively throughout the E.U. As a result, the complexity and cost of regulatory compliance of our European business has increased and will likely continue to result in elevated expenses.
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.

There were no material changes in our market risk components for the ninethree months ended September 30, 2020.March 31, 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, 20192020 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.

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, 2019 and our Quarterly Reports on Form 10-Q for each of the first two quarters of 2020, includeincludes a detailed discussionsdiscussion of certain material risk factors facing us. The information presented below describes updates and additions to such risk factors and should be read in conjunction with the risk factors and information disclosed in our Form 10-K10-K.
Any significant interruption in the operation of our business functions, facilities and restatessystems or our vendors' facilities and systems could result in their entiretya 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 cyber attacks, 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 following risk factors containedfactor 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 Quarterly Report on Form 10-Q forability 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 quarter ended June 30, 2020.ability to issue financial statements in a timely manner.
The COVID-19 pandemicforegoing risks could also expose us to monetary and measures to mitigatereputational damages. Potential exposures resulting from the spread ofMarch 2021 cybersecurity attack, described in the virusfollowing risk factor, as well as any future incidents may include substantially increased compliance costs and required computer system upgrades and security-related investments. If our business continuity plans or system security do not sufficiently address these risks, they could have resulted in significant risk across our enterprise, which have had, and may continue to have,a material adverse impactseffect on our business, results of operations and financial condition,condition.
Based on the extent of which cannot be determined with any certainty at this time.
The COVID-19 outbreak, and actions seeking to mitigate the spread of the virus, accelerated in both breadth and scope through the month of February, with the World Health Organization declaring it a pandemic on March 11, 2020. The situation has continued to evolve exponentially with implicated exposures increasing given sustained uncertainties across the global marketplace. Both the extensiveness of the pandemic itself, as well as the measures taken to mitigate the virus' spread globally, are unprecedented and their effects continue to be pervasive. In many geographic locations, the virus continues to spread. Accordingly, it remains the case that months past the initial identification of the threat, all of the direct and indirect consequences and implications of COVID-19 and measures to mitigate its spread are not yetinformation currently known, and may not emerge for some time.
Risks presented by the ongoing effects of COVID-19 that are known at this time include the following:
Broad economic impact
The economic effect of the pandemic has been broad in nature and has significantly impacted business operations across all industries, including ours. Depressed economic conditions have led to and may continue to lead to decreased insured exposures causing us to experience declines in premium volume, especially for lines of business that are sensitive to rates of economic growth and those that are impacted by audit premium adjustments. Significant decreases in premium volume directly and adversely impacts our underwriting expense ratio. In addition, certain customers, across a broad spectrum of industries and markets, have been and continue to be impacted by lost business, which may affect our ability to collect amounts owed to us by policyholders. We recorded a decrease in our estimated audit premiums during the second quarter of 2020 impacting our net earned premium and if general economic conditionswe do not improve inbelieve that the remainder of 2020 or thereafter, our net written premiums and net earned premiums may be depressed, which mayMarch 2021 cybersecurity attack will have a material impact on our business, results of operations or financial condition. However, no assurances can be given, and we may be subject to future incidents that could have a material adverse effect or result in operational impairments and financial condition, the extent of which cannot be determined with any certainty at this time.
While our losses incurred during the first nine months of 2020 related to COVID-19 and measures to mitigate its spread represent our best estimate of our ultimate insurance losses resulting from events occurring in the first nine months of 2020 due to the pandemic and the consequent economic crisis, given the unprecedented nature of this event, a high level of uncertainty exists as to the potential impact on insurance losses from these events or other events that might occur for the remainder of the year and thereafter. The scope, duration and magnitude of the direct and indirect effects could continue to evolve through the remainder of 2020, and possibly thereafter, and could materially impact our ultimate loss estimate, including in lines of business where losses have already been incurred, as well as significant harm to our reputation.
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 potential for impactspersonal information of our customers, claimants or employees, or sensitive and confidential information regarding our business and may

We sustained a sophisticated cybersecurity attack in March 2021 involving ransomware that caused a network disruption and impacted certain of our systems. Promptly upon detection, we undertook steps to experience additional COVID-19 related catastrophe losses in future quarters, which could be material.

The COVID-19 pandemic has also significantly impacted financial markets.notifying law enforcement and key regulators. As investors have embarked on a flight to quality, risk free rates have decreased.  In addition, liquidity concerns and overall economic uncertainties drove increased volatility in credit spreads and equity markets.  While government actions to date have provided some stability to financial markets, economic prospects in the short term continue to be depressed and we remain in a historically low interest rate environment. The unabated spread of the virusdate of this report, we have restored network systems and resumed normal operations. We are continuing to assess the extension of efforts to mitigate the spread in numerous geographic areas will continue to cause substantial uncertainty on the timing and strength of any economic recovery and could continue to impact our investment portfolio results and valuations, and may result in additional volatility or losses in our investment portfolio, which could be material.

These significant financial market disruptionsAlthough we maintain cybersecurity insurance coverage insuring against costs resulting from cyber attacks (including the attack described above), it is possible losses may exceed the amount available under our coverage and our coverage policy may not cover all losses. Further, future cybersecurity insurance coverage may be difficult to obtain or may only be available at significantly higher costs to us.
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. However, no assurances can be given, and financial condition, the extent of which cannot be determined with any certainty at this time.
Claims and related litigation
Claim activity and related litigation has increased, and may continue to increase significantly, in certain lines of business as a result of the pandemic and mitigating actions. We have experienced, and are likely to continue to experience, increased frequency in claim submissions in product lines that are implicated by the virus and the mitigating activities taken by our customers and governmental authorities in response to its spread, as well as increased litigation related to denial of claims based on policy coverage. These lines include primarily healthcare professional liability and workers' compensation, as well as commercial property-related business interruption coverage, management liability (directors and officers, employment practices, and professional liability lines) and trade credit. In addition, our surety lines may continue to experience increased losses, particularly in construction surety, where there is significant risk that contractors will be adversely and materially impacted by general economic conditions. We have recorded significant losses in these areas in the first nine months of 2020 and may experience continued losses, which could be material.
Increased frequency or severity in any or all of the foregoing lines, or others where the exposure has yet to emerge, may have a material impact on our business, results of operations and financial condition, the extent of which cannot be determined with any certainty at this time.
We have also begun to incur substantial expenses related to litigation activity in connection with COVID-related legal claims. These actions primarily relate to denial of claims submitted as a result of the pandemic and the mitigating actions under commercial property policies for business interruption coverage, including lockdowns and closing of certain businesses. The significance of such litigation, both in substance and volume, and the resultant activities we have initiated, including external counsel engagement, and the costs related thereto, may have a material impact on our business, results of operation and financial condition, the extent of which cannot be determined with any certainty at this time.
Regulatory impact
The regulatory environment is rapidly evolving in direct response to the pandemic and the mitigating actions being taken. Numerous regulatory authorities to which our business is subject have implemented or are contemplating broad and significant regulations restricting and governing insurance company operations during the pandemic crisis. Such actions include, but are not limited to, premium moratoriums, premium refunds and reductions, restrictions on policy cancellations and potential legislation-driven expansion of policy terms. To date, certain state authorities have ordered premium refunds and certain regulatory and legislative bodies have proposed requiring insurers to cover business interruption under policies that were not written to provide for such coverage under the current circumstances. In addition, certain states have directed expansion of workers’ compensation coverage through presumption of compensability of claims for a broad category of workers. This highly fluid and challenging regulatory environment, and the new regulations we are now, and may be subject to future incidents that could have such a material adverse effect or may have a

material impact on our business, results of operationresult in operational impairments and financial condition, the extent of which cannot be determined with any certainty at this time.
Business operational impact
Beginning on March 17, 2020, we instituted mandatory work from home for all of our employees, across the United States and globally, including Canada, the United Kingdom and Europe, and moved to teleconference meetings only across the enterprise. As of the date of this report, the work from home mandate remains in place across the majority of our global workforce. Mandatory work from home may impact the productivity of our workforce, and increases the risk of information security exposure. Disruptions to our employees’ productivity,losses, as well as their health and welfare, especially in the context of accelerated contagion of the virus (which has not occurred across our employee population at this time), along with the heightened security risks presented by widespread remote accesssignificant harm to our computer systems, may have a material impact onreputation.

In addition, in virtually all cases, our critical vendors have also had to impose workplace restrictions or work from home mandates on their employees, which may result in interruption in service delivery or failure by vendors to properly perform required services, including delivery in a manner more susceptible to significant information security risk. Such vendor issues may result in a material impact on our business operations, the extent of which cannot be determined with any certainty at this time.
