CNA Financial Corporation
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% of the outstanding common stock of CNAF as of March 31, 2019.2020.
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, 2018,2019, 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 March 31, 20192020 and for the three months ended March 31, 20192020 and 20182019 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 2016-02: 2016-13:In FebruaryJune 2016 the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (Topic 842): Accounting for Leases. The updated accounting guidance requires lessees to recognize on the balance sheet assets and liabilities for the rights and obligations created by the majority of leases, including those historically accounted for as operating leases. On January 1, 2019, the Company adopted the updated guidance using a modified retrospective method. Prior period amounts have not been adjusted and continue to be reported in accordance with the previous accounting guidance. The Company utilized the package of practical expedients allowing the Company to not reassess whether a contract is or contains a lease, lease classification and initial direct costs. The Company also utilized the practical expedient to not separate lease and non-lease components for all leases.
Adoption of the updated guidance resulted in the following changes to the Condensed Consolidated Balance Sheet on January 1, 2019:
(In millions)Balance as of December 31, 2018 Adjustments Due to Adoption of Topic 842 Balance as of January 1, 2019

Operating lease right-of-use (ROU) assets, included within Other assets, were reduced by accrued rent and lease incentives of $75 million previously classified as Other liabilities. The updated guidance did not impact the Condensed Consolidated Statements of Operations. See Note K to the Condensed Consolidated Financial Statements for additional information regarding leases.

Accounting Standards Pending Adoption
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurementof Credit Losses on Financial Instruments. Instruments. The updated accounting guidance requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income. The guidance is effective for interim and annual periods beginning after December 15, 2019. The guidance will be applied using a modified retrospective approach with the cumulative effect recognized as an adjustment to retained earnings. A prospective transition approach is required for debt securities that have recognized an other-than-temporary impairment prior to the effective date. The Company is currently evaluating the effect the guidance will have on the Company'sCompany’s results of operations. For financial statements, but expects the primary changes to be the use ofassets measured at cost, the expected credit loss model for its mortgage loan portfolio, reinsurance and insurance receivables and other financing receivables andrequires immediate recognition of estimated credit losses over the uselife of the allowance method rather thanasset and presentation of the write-down method for credit losses within the available-for-sale fixed maturities portfolio. The expected credit loss model will require a financial asset to be presented at the net amount expected to be collected. TheThis 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 method for available-for-sale debt securities will allow the Company to recordand reversals of credit lossesthe 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 in the quarter that payment becomes 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 Net incomethe 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, 2020,2021, and the Company will adopt it on January 1, 2022. The guidance requires restatement of the prior periods presented. Early adoption is permitted. The Company is currently evaluating the method and timing of adoption and the effect the updated guidance will have on its financial statements.statements, including the increased disclosure requirements. The annual updating of cash flow assumptions is expected to increase income statement volatility. The quarterly change in discount rate is expected to increase volatility in the Company’s stockholders' equity, but that will be somewhat mitigated because Shadow Adjustments are eliminated under the new guidance. While the requirements of the new guidance represent a material change from existing GAAP, the underlying economics of the business and related cash flows arewill be unchanged.

Note B. Earnings (Loss) Per Share
Earnings (loss) per share is based on the weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the impact of dilutive securities and is computed by dividing Net income (loss) 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 months ended March 31, 2020, approximately 1,015 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were excluded from the calculation of diluted loss per share because the effect would have been antidilutive due to the net loss position of the Company. For the three months ended March 31, 2019, and 2018, approximately 971 thousand and 1,009 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 the three months ended March 31, 2018 approximately 9 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were not included in the calculation of diluted earnings per share, because the effect would have been antidilutive. For the three months ended March 31, 2019 there were no0 antidilutive shares.
The Company repurchased 435,376 and 317,508 shares of CNA Financial CorporationCNAF common stock at an aggregate cost of $18 million and $14 million during the three months ended March 31, 2020 and 2019. No repurchases were made during 2018.

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 are presented as a component of Net investment gains (losses) on the Condensed Consolidated Statements of Operations.

The following table presents the activity related to the allowance on available-for-sale securities with credit impairments and PCD assets for the three months ended March 31, 2020. Accrued interest receivable on available-for-sale fixed maturity securities totaled $390 million 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 AOCI.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 March 31, 20192020 and December 31, 2018,2019, the net unrealized gains on investments included in AOCI were correspondingly reduced by Shadow Adjustments of $1,458$1,700 million and $1,078$2,198 million.

The following tables present the estimated fair value and gross unrealized losses of fixed maturity securities in a gross unrealized loss position for which an allowance for credit loss has not been recorded, by the length of time in which the securities have continuously been in that position.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the March 31, 2019 securities in a2020 gross unrealized loss position tabletables above are not indicative of the ultimate collectibility of the current amortized cost of the securities, but rathersecurities. Rather, the Company believes the gross unrealized losses are attributable primarily to changes in interest rates,widening credit spreads and other factors.over risk free rates beyond historic norms, as a result of market uncertainties stemming from the COVID-19 pandemic, as well as supply shocks in the energy sector coupled with demand shocks in multiple sectors from the COVID-19 pandemic, that originated during the first quarter of 2020. 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 OTTIimpairment losses to be recorded as of March 31, 2019.
The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of March 31, 2019 and 2018 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

to privately placed debt securities. As of March 31, 2019, the Company had mortgage loan commitments of $9 million representing signed loan applications received and accepted.
The Company invests in various privately placed debt securities, including bank loans, as part of its overall investment strategy and has committed to additional future purchases, sales and funding. Purchases and sales of privately placed debt securities are recorded once funded. As of March 31, 2019,2020, the Company had commitments to purchase or fund additional amounts of $283approximately $1,025 million and sell $150approximately $85 million under the terms of such securities.these investments.
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 Company has adjusted the historical loss rate applied to mortgage loans over the forecast period to reflect higher expected credit losses based on observable economic forecasts, which increased the allowance by $13 million for the period ended March 31, 2020.

The following table presents the amortized cost basis of mortgage loans for each credit quality indicator by year of origination as of March 31, 2020:

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 and v) pricing validation, where prices received are compared to prices independently estimated by the Company.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.

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, and redeemable preferred stock, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. 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 March 31, 20192020 and December 31, 2018,2019, there were approximately $54$58 million and $48$60 million of overseas deposits within otherOther 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
Level 2 investments primarily include the embedded derivative on the funds withheld liability. 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.

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.

The following methods and assumptions were used to estimate the fair value of these financial assets and liabilities.
The fair valuesvalue of mortgage loans werewas based on the present value of the expected future cash flows discounted at the current interest rate for origination of similar quality loans, adjusted for specific loan risk.
The fair value of the note receivable was based on the present value of the expected future cash flows discounted at the current interest rate for origination of similar notes, adjusted for specific credit risk. TheDuring the three months ended March 31, 2020, the note receivable iswas repaid in full. As of December 31, 2019, the note receivable was included within Other assets on the Condensed Consolidated Balance Sheets.
The Company's senior notes and debentures were valued based on observable market prices. The fair value for other debt was estimated using discounted cash flows based on current incremental borrowing rates for similar borrowing arrangements.
The carrying amounts reported on the Condensed Consolidated Balance Sheets for Cash, Short term investments not carried at fair value, Accrued investment income and certain Other assets and Other liabilities approximate fair value due to the short term nature of these items. These assets and liabilities are not listed in the tables above.

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 $58$75 million and $34$58 million for the three months ended March 31, 20192020 and 2018.2019. Net catastrophe losses infor the first quarter ofthree months ended March 31, 2020 included $13 million related to the COVID-19 pandemic, with the remaining $62 million related primarily to U.S. weather related events. Net catastrophe losses for the three months ended March 31, 2019 and 2018 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 in the Condensed Consolidated Statements of Operations.
The following table presents the impact of the Loss Portfolio TransferLPT on the Condensed Consolidated Statements of Operations.

The Company intends to complete its annual A&EP reserve review inOperations was the fourth quarterrecognition of 2019a retroactive reinsurance benefit of $14 million and maintain this timing for all future annual A&EP reserve reviews. The Company completed A&EP reserve reviews in both the first and fourth quarters of 2018. Based upon the Company's 2018 first quarter A&EP reserve review, net unfavorable prior year development of $113$22 million was recognized before consideration of cessions to the LPT for the three months ended March 31, 2018. The 2018 unfavorable development was driven by higher than anticipated defense costs on direct asbestos2020 and environmental accounts and paid losses on assumed reinsurance exposures. Additionally, in 2018, the Company released a portion of its provision for uncollectible third-party reinsurance.
2019. As of March 31, 20192020 and December 31, 2018,2019, the cumulative amounts ceded under the LPT were $3.1$3.2 billion. The unrecognized deferred retroactive reinsurance benefit was $352$378 million and $374$392 million as of March 31, 20192020 and December 31, 20182019 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 $3.0$2.7 billion and $2.7$3.7 billion as of March 31, 20192020 and December 31, 2018.2019. The decrease in the fair value of the trust was driven by overall declines in equity markets. As of March 31, 2020, the fair market value of the trust represented more than 150% of the gross LPT reserves. 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.

Note F. Legal Proceedings, Contingencies and Guarantees
The Company is a party to routinevarious claims and litigation incidental to its business, which, based on the facts and circumstances currently known, isare not material to the Company's results of operations or financial position.
Guarantees
As of March 31, 20192020 and December 31, 2018,2019, the Company had recorded liabilities of approximately $5 million related to guarantee and indemnification agreements and managementagreements. Management does not believe that any future indemnity claims will be significantly greater than the amounts recorded.
In the course of selling business entities and assets to third parties, the Company agreed to guarantee the performance of certain obligations of previously owned subsidiaries and to indemnify purchasers for losses arising out of breaches of representations and warranties with respect to the business entities or assets sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation. Such guarantee and indemnification agreements in effect for sales of business entities, assets and third-party loans may include provisions that survive indefinitely. As of March 31, 2019, the aggregate amount related to quantifiable guarantees was $375 million and the aggregate amount related to quantifiable indemnification agreements was $252 million. In certain cases, should the Company be required to make payments under any such guarantee, it would have the right to seek reimbursement from an affiliate of a previously owned subsidiary.
In addition, the Company has agreed to provide indemnification to third-party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount. As of March 31, 2019, the Company had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. Certain provisions of the indemnification agreements survive indefinitely, while others survive until the applicable statutes of limitation expire, or until the agreed-upon contract terms expire.
The Company alsohas provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities providedissued by a previously owned subsidiary. As of March 31, 2019,2020, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $1.7 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 three3 business segments: Specialty, Commercial and International. These three3 segments are collectively referred to as Property & Casualty Operations. The Company's operations outside of Property & Casualty Operations are managed and reported in two2 segments: Life & Group and Corporate & Other.
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, 2018.2019. 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 i) net investment gains (losses), ii) income or loss from discontinued operations, iii)losses and any cumulative effects of changes in accounting guidance and iv) deferred tax asset and liability remeasurement as a result of an enacted U.S. Federal tax rate change.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 consistent with key driversreflective of underwriting performance, and are therefore not considered an indication of trends in insuranceour primary operations.


The Company's results of operations and selected balance sheet items by segment are presented in the following tables.

Note K. LeasesExpected Credit Losses - Uncollectible Reinsurance and Insurance Receivables
A lease provides the lessee the right to control the use of an identified asset for a period of time in exchange for consideration. Operating lease ROU assets and lease liabilities are included in Other assets and Other liabilities on the Company's Condensed Consolidated Balance Sheets.
ROU assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. The Company determines ifhas established an arrangementallowance 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 a lease at inception. Operating lease ROU assets and liabilities are recognized atno perceived credit risk. The principal credit quality indicator used in the lease commencement datevaluation 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 present valueCompany’s historical loss experience and the Company’s assessment of lease payments over the lease term. Most operating leases contain renewal options that provide for rent increases based on prevailing market conditions. Certain leases contain options to terminate before maturity. The lease term used to calculate the ROU asset includes any renewal options or lease termination that the Company expects to exercise. The discount rate used to determine the commencement date present value of lease payments is the interest rate implicitreinsurance counterparty risk profile, which generally corresponds with a B rating. Changes in the lease, or when that is not readily determinable,allowance are presented as a component of Insurance claims and policyholders' benefits on the Company utilizes its secured borrowing rate. ROU assets include any lease payments required to be made prior to commencement and exclude lease incentives. Both ROU assets and lease liabilities exclude variable payments not based on an index or rate, which are treated as period costs. The Company's lease agreements do not contain significant residual value guarantees, restrictions or covenants.Condensed Consolidated Statements of Operations.
The Company occupies office facilities under lease agreements that expire at various dates. In addition, data processing, office and transportation equipment is leased under agreements that expire at various dates. The Company’s leases generally include lease and non-lease components, whichfollowing table summarizes the Company has elected to account for as a single lease component. Variable lease costs not based on an index or rate consistoutstanding amount of non-lease components, which are being accounted for as lease components, and represent charges for services providedvoluntary reinsurance receivables, gross of any collateral arrangements, by the landlord and our reimbursement for the landlord’s costs, including real estate taxes and insurance. The Company does not have any significant finance leases.
Operating lease cost was $10 million and variable lease cost was $4 million for the three months ended March 31, 2019. Cash paid for amounts included in operating lease liabilities was $8 million for the three months ended March 31, 2019.

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, andas well as the supplemental risk factor regarding the COVID-19 pandemic 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, 2018.2019.
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 i) net investment gains or losses ii) income or loss from discontinued operations, iii)and any cumulative effects of changes in accounting guidance and iv) deferred tax asset and liability remeasurement as a result of an enacted U.S. Federal tax rate change.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 consistent with key driversreflective of underwriting performance, and are therefore not considered an indication of trends in insuranceour 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 expense ratio, the dividend ratio and the combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The expense ratio is the percentage of insurance underwriting and acquisition expenses, including the amortization of deferred acquisition costs, to net earned premiums. The dividend ratio is the ratio of policyholders' dividends incurred to net earned premiums. The combined ratio is the sum of the loss, expense and dividend ratios. 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 mostly 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
Long Term Care Policies
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, 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, 20182019 for further information.

CONSOLIDATED OPERATIONS
Results of Operations
The following table includesCOVID-19 pandemic and global, national, regional and local efforts to mitigate the consolidatedspread of the virus have rapidly evolved and led to severely depressed economic conditions and financial market disruption, primarily beginning in the month of March. These conditions have had an impact across our enterprise during the first quarter of 2020. While the impact to our underwriting results was limited, we experienced significant declines in the value of our investment portfolio during the first quarter. Currently, we believe the future impact across our operations is likely to be reflected in continued volatility in our investment portfolio, and adverse effects on our underwriting results including our financial measure, core income (loss).decreased premiums, elevated expenses in the form of credit losses for uncollectible receivables, and increased claims reporting activity and related litigation, due to both the pandemic and depressed economic conditions. For more discussion of COVID-19 impacts on our underwriting results and detailed components of our business operations and a discussion of the core income (loss) financial measure, see the segment sections within this MD&A. For further discussion of Net investment income and Net investment results,gains or losses, see the Investments section of this MD&A. For further discussion of the risks to our business associated with COVID-19, see the Risk Factor included under Part II, Item 1A of this Form 10-Q.

Core income increased $37decreased $210 million for the three months ended March 31, 20192020 as compared with the same period in 2018.2019. Core income for our Property & Casualty Operations decreased $13$192 million primarily due to lower underwriting income partially offset by higher net investment income driven by limited partnership and common stock returns. Our underwriting results for the three months ended March 31, 2020 included a $15 million pretax ($12 million after-tax) loss related to COVID-19 comprised of claims activity included in catastrophe losses and an increase in our allowance for uncollectible insurance receivables. Core income for our Life & Group segment decreased $4$6 million while the core loss for our Corporate & Other segment improved $54increased $12 million.
Net catastrophe losses were $58$75 million and $34$58 million for the three months ended March 31, 20192020 and 2018.2019. Catastrophe losses for the three months ended March 31, 2020 include $13 million related to COVID-19, which is being tracked as a separate catastrophe event. Favorable net prior year loss reserve development of $14$15 million and $39$14 million was recorded in the three months ended March 31, 20192020 and 20182019 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
The impact COVID-19 had on our insurance underwriting results was more limited in the first quarter of 2020 than we anticipate occurring in the second and third quarters of 2020, and possibly thereafter, as the situation continues to evolve. Currently, we believe the future impact on our underwriting results is likely to include declines in premium volume, driven by slower growth, especially for lines of business that are sensitive to rates of economic growth, as well as policy cancellations, refunds or return of premiums, as a result of decreased insured exposures for our current policyholders. In addition, many of our customers, across a broad spectrum of industries, are likely to be impacted by lost business, which may affect our ability to collect amounts owed to us, increasing our expenses for credit losses for uncollectible premiums. Lower premiums and higher expenses will result in an increase to our expense ratio. Further, while loss frequency may decrease related to lower exposures in certain lines, we expect an overall increase in insurance claims reporting activity and related litigation due to both the pandemic and depressed economic conditions. This includes increased frequency in claim submissions in lines that are implicated by the virus and the mitigating activities taken by our customers and governmental authorities in response to its spread. These include workers’ compensation, healthcare, commercial property coverage, and directors’ and officers’ liability and employment practices liability lines. In addition, our surety lines may experience increased losses, particularly in construction surety, where there is risk that contractors will be adversely impacted by general economic conditions. The costs associated with claims handling and defense, as well as the payment of claims for covered exposures, will likely increase our loss ratio. For further discussion of the risks to our business associated with COVID-19, see the Risk Factor included under Part II, Item 1A of this Form 10-Q.
The following discusses the results of operations for our business segments.segments during the first quarter of 2020. 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.

INVESTMENTS
The financial market disruption in the first quarter of 2020 significantly impacted our investment portfolio during the period. Losses from our limited partnership and common and preferred equity portfolios, as well as the recognition of impairment losses on certain fixed maturity holdings, have negatively impacted our net income. Additionally, the overall fair value of our available for sale fixed maturity portfolio has declined, primarily as a result of credit spread widening. We currently expect some level of continued volatility in our investment portfolio as the situation continues to evolve.

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, 2018.2019.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our primary operating cash flow sources are premiums and investment income from our insurance subsidiaries. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.
Related to the COVID-19 pandemic and efforts to mitigate the spread of the virus, cash flows may be adversely impacted by lower premium volumes, suspensions and cancellations of policies, return of premiums or premium refunds, and increased claim and defense cost payments in future quarters. 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 three months ended March 31, 2019,2020, net cash provided by operating activities was $287$212 million as compared with $218$287 million for the same period in 2018.2019. The increasedecrease in cash provided by operating activities was driven by higher net claim payments and a higherlower level of distributions onfrom limited partnerships.partnerships partially offset by an increase in premiums collected.
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, land, buildings, equipment and other assets not generally held for resale.
Net cash provided by investing activities was $289$1,087 million for the three months ended March 31, 2019,2020, as compared with $489$289 million for the same period in 2018.2019. The cash flow from investing activities is affected by various factors such as the anticipated payment of claims, financing activity, asset/liability management and individual security buy and sell decisions made in the normal course of portfolio management.
Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, and outflows for stockholder dividends, or repayment of debt and outlays to reacquire equity securities.purchases of treasury stock.
For the three months ended March 31, 2019,2020, net cash used by financing activities was $665$675 million as compared with $781$665 million for the same period in 2018.2019. In the first quarter of 2020, we paid dividends of $649 million and repurchased 435,376 shares of our common stock at an aggregate cost of $18 million. In the first quarter of 2019, we paid dividends of $643 million and repurchased 317,508 shares of our common stock at an aggregate cost of $14 million. In the first quarter of 2018, we paid dividends of $624 million and redeemed the $150 million outstanding aggregate principal balance of our 6.950% senior notes due January 15, 2018.
Common Stock Dividends
A quarterly dividend of $0.35$0.37 per share and a special dividend of $2.00 per share of our common stock were declared and paid in the first quarter of 2019.2020. On April 26, 2019,May 1, 2020, our Board of Directors declared a quarterly dividend of $0.35$0.37 per share, payable May 30, 2019June 4, 2020 to stockholders of record on May 13, 2019.18, 2020. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs and regulatory constraints.

Liquidity
We believe that our present cash flows from 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 billion of cash, short term investments and highly liquid securities issued by US government agencies as of March 31, 2020, of which $506 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 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 March 31, 2019,2020, CCC was in a positive earned surplus position. The maximum allowable dividend CCC could pay during 20192020 that would not be subject to the Department's prior approval is $1,383$1,078 million, less dividends paid during the preceding twelve months measured at that point in time. CCC paid dividends of $356$125 million during the ninethree months ended June 30, 2019, $135 million during the three months ended September 30, 2019, $125 million during the three months ended December 31, 20182019 and $680$670 million during the three months ended March 31, 2019.2020. As of March 31, 2019,2020, CCC is able to pay approximately $347$23 million of dividends that would not be subject to prior approval of the Department. 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 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, 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 for long term care, A&EP and other mass tort claims which are more uncertain, and therefore more difficult to estimate than loss reserves respecting traditional property and casualty exposures; the impact of routine ongoing insurance reserve reviews we are conducting; our expectations concerning our revenues, earnings, expenses and investment activities; volatility in investment returns; expected cost savings and other results from our expense reduction activities; and our proposed actions in response to trends in our business. Forward-looking statements, by their nature, are subject to a variety of inherent risks and uncertainties that could cause actual results to differ materially from the results projected in the forward-looking statement. We cannot control many of these risks and uncertainties. These risks and uncertainties include, but are not limited to, the following:
Company-Specific Factors
the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of our 2019 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, as economic uncertainty and depressed business conditions brought on by the crisis may materially and adversely impact our business, driving significant decreases in our premium volume and resulting in significant losses in our investment portfolio, 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 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

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 Factors
regulatory and legal initiatives and compliance with governmental regulations and other legal requirements, including with respect to cyber security protocols, 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; and
regulatory limitations and restrictions, including limitations upon our ability to receive dividends from our insurance subsidiaries, imposed by regulatory authorities, including regulatory capital adequacy standards.

the occurrence of epidemics.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.
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.” BrexitWhile the withdrawal of the U.K. from the E.U. was official as of January 31, 2020, until the transition period ends, there remains scheduled toa lack of specificity and detail regarding the long term relationship between the two sides and how businesses operating in both jurisdictions may be completed in 2019, although the formal exit has been delayed twice. Effectiveaffected. In any event, effective January 1, 2019, we writeour E.U. business in the E.U.is no longer handled out of our U.K.-domiciled subsidiary, but through our recently established European subsidiary in Luxembourg, which was established specifically to address the departure of the U.K. from the E.U. and not through our U.K.-domiciled subsidiary.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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
There were no material changes in our market risk components for the three months ended March 31, 2019.2020. 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, 20182019 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 March 31, 2019,2020, 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 March 31, 2019.2020.
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 March 31, 20192020 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, 2019, includes a detailed discussion 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-K.
The COVID-19 pandemic and mitigating actions have resulted in significant risk across our enterprise, which may have a material adverse impact on our business, results of operations and financial condition, 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. Because of the extensiveness of the pandemic, all of the direct and indirect consequences and implications of COVID-19 are not yet 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 may 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. Significant decreases in premium volume would also directly and adversely impact our underwriting expense ratio. In addition, many of our customers, representing a broad spectrum of industries and markets, may potentially be impacted by lost business, which may affect our ability to collect amounts owed to us by policyholders.
The COVID-19 pandemic has also significantly impacted the financial markets. As investors embark on a flight to quality, risk free rates have decreased. In addition, extreme market volatility due to liquidity concerns and overall uncertainties have driven widening credit spreads and declining equity markets. These conditions have impacted our investment portfolio results and valuations and may continue to do so, resulting in additional losses in our investment portfolio. The value of our fixed maturity investments is subject to risk that certain investments may default or become impaired due to deterioration in the financial condition of issuers of the investments we hold or in the underlying collateral of the security or loan, particularly in industries heavily impacted by COVID-19 and mitigating actions, including energy, retail, travel, entertainment, and real estate. Our municipal bond portfolio is also subject to risks of default by state and local governments and agencies that are under increased strain related to the pandemic.
These significant economic and financial market disruptions 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.

Claims activity
Another aspect is claim activity and related litigation, which may increase significantly in certain of our lines of business as a result of the pandemic and mitigating actions. We may experience increased frequency in claim submissions in 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 potential regulatory or legislative actions that are further described below under Regulatory impact. These include workers’ compensation, healthcare, commercial property coverage, and directors’ and officers’ liability and employment practices liability lines. In addition, our surety lines may experience increased losses, particularly in construction surety, where there is significant risk that contractors will be adversely and materially impacted by general economic conditions. 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 effect on our business, results of operations 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 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.
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 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, 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 access to our computer systems, may have a material impact on our business operations, the extent of which cannot be determined with any certainty at this time.
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.
