PART I
ITEM 1. BUSINESS
CNA Financial Corporation (CNAF) was incorporated in 1967 and is an insurance holding company. References to “CNA,” the Company,” “we,” “our,” “us” or like terms refer to the business of CNAF and its subsidiaries. CNA's property and casualty and remaining life and group insurance operations are primarily conducted by Continental Casualty Company (CCC), The Continental Insurance Company, Western Surety Company, CNA Insurance Company Limited, Hardy Underwriting Bermuda Limited and its subsidiaries (Hardy), and CNA Insurance Company (Europe) S.A. Loews Corporation (Loews) owned approximately 89.6% of our outstanding common stock as of December 31, 2020.
Our insurance products primarily include commercial property and casualty coverages, including surety. Our services include warranty, risk management information services and claims administration. Our products and services are primarily marketed through independent agents, brokers and managing general underwriters to a wide variety of customers, including small, medium and large businesses, insurance companies, associations, professionals and other groups. The property and casualty insurance industry is highly competitive, both as it relates to rate and service. We compete with a large number of stock and mutual insurance companies, as well as other entities, for both distributors and customers.
Our commercial property and casualty underwriting operations presence in the United States of America (U.S.) consists of field underwriting locations and centralized processing operations which handle policy processing, billing and collection activities and also act as call centers to optimize service. Our claim operations in the U.S. consists of primary locations where we handle multiple claim types and key business functions, as well as regional claim offices which are aligned with our underwriting field structure. We have property and casualty underwriting operations in Canada, the United Kingdom (U.K.) and Continental Europe, as well as access to business placed at Lloyd's of London through Syndicate 382.
Our commercial property and casualty 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 business segments: Life & Group and Corporate & Other. Each segment is managed separately due to differences in their markets and product mix. Discussion of each segment, including the products offered, customers served and distribution channels used, is set forth in the Management's Discussion and Analysis (MD&A) included under Item 7 and in Note O to the Consolidated Financial Statements included under Item 8.
Current Regulation
The insurance industry is subject to comprehensive and detailed regulation and supervision. Regulatory oversight by applicable agencies is exercised through review of submitted filings and information, examinations (both financial and market conduct), direct inquiries and interviews. Each domestic and foreign jurisdiction has established supervisory agencies with broad administrative powers relative to licensing insurers and agents, approving policy forms, establishing reserve requirements, prescribing the form and content of statutory financial reports and regulating capital adequacy and the type, quality and amount of investments permitted. Such regulatory powers also extend to premium rate regulations requiring rates not be excessive, inadequate or unfairly discriminatory. In addition to regulation of dividends by insurance subsidiaries, intercompany transfers of assets or payments may be subject to prior notice or approval by insurance regulators, depending on the size of such transfers and payments in relation to the financial position of the insurance subsidiaries making the transfer or payments.
As our insurance operations are conducted in both domestic and foreign jurisdictions, we are subject to a number of regulatory agency requirements applicable to a portion, or all, of our operations. These include but are not limited to, the State of Illinois Department of Insurance (which is our global group-wide supervisor), the U.K. Prudential Regulatory Authority and Financial Conduct Authority, the Office of Superintendent of Financial Institutions in Canada, the Luxembourg insurance regulator Commissariat aux Assurances (the CAA) and the Bermuda Monetary Authority.

The U.S. and foreign regulatory environment in which we operate is evolving on an ongoing basis and impacts aspects of corporate governance, risk management practices, public disclosures and cyber security. We continue to invest in the security of our systems and network on an enterprise-wide basis.
Domestic insurers are also required by state insurance regulators to provide coverage to certain insureds who would not otherwise be considered eligible by the insurers. Each state dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each state.
Further, domestic insurance companies are subject to state guaranty fund and other insurance-related assessments. Guaranty funds are governed by state insurance guaranty associations which levy assessments to meet the funding needs of insolvent insurer estates. Other insurance-related assessments are generally levied by state agencies to fund various organizations, including disaster relief funds, rating bureaus, insurance departments and workers' compensation second injury funds, and by industry organizations that assist in the statistical analysis and ratemaking process, and we have the ability to recoup certain of these assessments from policyholders.
Although the U.S. federal government does not currently directly regulate the business of insurance, federal legislative and regulatory initiatives can affect the insurance industry. These initiatives and legislation include proposals relating to terrorism and natural catastrophe exposures, cybersecurity risk management, federal financial services reforms and certain tax reforms.
The Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA) provides for a federal government backstop for insured terrorism risks through the end of 2027. The mitigating effect of such law is part of the analysis of our overall risk posture for terrorism and, accordingly, our risk positioning may change if such law was modified.
Hardy, a specialized Lloyd's of London (Lloyd's) underwriter, is also supervised by the Council of Lloyd's, which is the franchisor for all Lloyd's operations. The Council of Lloyd's has wide discretionary powers to regulate Lloyd's underwriting, such as establishing the capital requirements for syndicate participation. In addition, the annual business plan of each syndicate is subject to the review and approval of the Lloyd's Franchise Board, which is responsible for business planning and monitoring for all syndicates.
The transition period for the U.K.’s exit from the European Union (E.U.), commonly referred to as “Brexit,” ended on December 31, 2020. To ensure the Company’s ability to operate effectively throughout the E.U. following the departure of the U.K. from the trading bloc, effective January 1, 2019, our E.U. business is no longer written by the U.K.-domiciled subsidiary Hardy, but through a European subsidiary established in Luxembourg. 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.
Capital adequacy and risk management regulations, referred to as Solvency II, apply to our European operations and are enacted by the European Commission, the executive body of the E.U. Additionally, the International Association of Insurance Supervisors (IAIS) continues to develop capital requirements as more fully discussed below.
Regulation Outlook
The IAIS has adopted a Common Framework (ComFrame) for the Supervision of Internationally Active Insurance Groups (IAIGs) which is focused on the effective group-wide supervision of internationally active insurance groups, such as CNA. As part of ComFrame, the IAIS is developing a global insurance capital standard for insurance groups. While the general parameters of ComFrame have been finalized, many critical areas of the global insurance capital standard are still under consideration. Certain jurisdictional regulatory regimes are subject to revision in response to these global developments.
The National Association of Insurance Commissioners (NAIC) has developed an approach to group capital regulation and solvency-monitoring activities using the Group Capital Calculation (GCC). While the current U.S. regulatory regime is based on legal entity regulation, the GCC will quantify risk across the insurance group and also provide additional financial information to regulators to assess the financial condition of non-insurance

Table of Contents
entities. The GCC was recently adopted by the NAIC along with model legislative language designed to enable the framework once implemented by state legislatures. Alongside the GCC, the NAIC is also working with other interested jurisdictions, both domestic and international, to develop an Aggregation Method (AM) approach to assessing group capital. The AM is influenced by the GCC and calculated in a similar manner. By 2024, the IAIS will be assessing whether the AM provides comparable outcomes to the consolidated group insurance capital standard (ICS) being developed for use with IAIGs.
There have also been definitive developments with respect to prudential insurance supervision unrelated to the IAIS activities. On September 22, 2017, the U.S. Treasury Department, the U.S. Trade Representative (USTR) and the E.U. announced they had formally signed a covered agreement on Prudential Measures Regarding Insurance and Reinsurance (U.S.-E.U. Covered Agreement). The U.S.-E.U. Covered Agreement requires U.S. states to prospectively eliminate the requirement that domestic insurance companies must obtain collateral from E.U. reinsurance companies that are not licensed in their state (alien reinsurers) in order to obtain reserve credit under statutory accounting. In exchange, the E.U. will not impose local presence requirements on U.S. firms operating in the E.U., and effectively must defer to U.S. group capital regulation for these firms. On December 18, 2018, the U.S. Treasury Department, the USTR, and the U.K. announced they formally signed the Bilateral Agreement on Prudential Measures Regarding Insurance and Reinsurance (U.S.-U.K. Covered Agreement). This Agreement has similar terms as the U.S.-E.U. Covered Agreement. Because these covered agreements are not self-executing, U.S. state laws will need to be revised to change reinsurance collateral requirements to conform to the provisions within each of the agreements.
Both the reinsurance collateral requirement change and adoption of group capital regulation must be effected by the states within five years from the signing of the covered agreements, or states risk federal preemption. We will monitor the modification of state laws and regulations in order to comply with the provisions of the covered agreements and assess potential effects on our operations and prospects.
Human Capital
As of December 31, 2020, we had approximately 5,800 employees. We believe we are able to attract and retain top talent by creating a culture that challenges and engages our employees, offering them opportunities to learn, grow and achieve their career goals. Further, our commitment to a culture of inclusion is integral to our goal of attracting and retaining the best talent and ultimately driving our business performance. Our Diversity and Inclusion strategy includes employee-led resource groups, regular training and development for all employees and partnerships with diverse colleges, universities and non-profit organizations that share in our inclusion mission. We also have an established corporate social responsibility strategy with a focus on four core areas: education, environment, inclusion and well-being. Our employees participate in a wide array of volunteer activities and we support their charitable giving by matching employee contributions to qualified nonprofit organizations.
We offer comprehensive compensation and benefits packages to our employees including a 401k Plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off and certain family assistance programs, including paid family leave, flexible work arrangements and adoption assistance plans, amongst others. We also offer stock-based compensation to certain management personnel as a way to attract and retain key talent. See Notes I and J to the Consolidated Financial Statements included under Item 8 for further discussion of our benefit plans and stock-based compensation.
In response to the COVID-19 pandemic in March 2020, we pivoted to a remote working environment for substantially all of our employees with a commitment to the safety of our employees and the communities we serve. In the fourth quarter we began re-opening some offices on a voluntary basis to accommodate employees seeking the flexibility to work from the office, while carefully monitoring the conditions in those areas and continuing to adhere to health and safety protocols.

ITEM 1A. RISK FACTORS
Our business faces many risks and uncertainties. These risks and uncertainties could lead to events or circumstances that have a material adverse effect on our results of operations, equity, business and insurer financial strength and corporate debt ratings. We have described below material risks that we face. There may be additional risks that we do not yet know of or that we do not currently perceive to be material that may also affect our business. You should carefully consider and evaluate all of the information included in this report and any subsequent reports we may file with the SEC or make available to the public before investing in any securities we issue.
COVID-19 Risks
The COVID-19 pandemic and measures to mitigate the spread of the virus have resulted in significant risk across our enterprise, which have had, and may continue to have, material adverse impacts 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 early 2020, 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. While vaccination efforts have begun, in many geographic locations, the virus continues to spread. Accordingly, it remains the case that nearly a year 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 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 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. We recorded a decrease in our estimated audit premiums during the second quarter of 2020 impacting our net earned premium and if general economic conditions do not improve, our net written premiums and net earned premiums may be depressed, which 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.
While our losses incurred during 2020 related to COVID-19 and measures to mitigate its spread represent our best estimate of our ultimate insurance losses resulting from events occurring during 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 in the future. The scope, duration and magnitude of the direct and indirect effects could continue to evolve, 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 full or partial business closures, could cause us to experience additional COVID-19 related catastrophe losses in future quarters, which could be material. For further discussion of risks associated with catastrophe losses, see the Risk Factor, "We are vulnerable to material losses from natural and man-made disasters."

Financial Markets and Investments
The COVID-19 pandemic has also significantly impacted financial markets. 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 continued spread of the virus and 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 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. For further discussion of risks associated with our investments, see the Risk Factor, “We may incur significant realized and unrealized investment losses and volatility in net investment income arising from changes in the financial markets.”
Claims and related litigation
We have experienced, and are likely to continue to experience, increased claim submissions and litigation related to denial of claims based on policy coverage, in certain lines of business that are implicated by the pandemic and mitigating actions taken by our customers and governmental authorities in response to its spread. These lines include primarily healthcare professional liability, workers' compensation, commercial property-related business interruption coverage, management liability (directors and officers, employment practices, and professional liability lines) and trade credit. We have recorded significant losses in these areas during 2020 and may experience continued losses, which could be material. 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 a prolonged decline in 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 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 incurred and may continue 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 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 related mitigating actions. 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. For further discussion of risks associated with our regulatory environment, see the Risk Factor, “We are subject to extensive existing state, local, federal and foreign governmental regulations that restrict our ability to do business and generate revenues; additional

Table of Contents
regulation or significant modification to existing regulations or failure to comply with regulatory requirements may have a materially adverse effect on our business, results of operations and financial condition.”
Business operational impact
Beginning in March 2020, we instituted mandatory work from home for our employees, with the exception of employees performing certain essential operations, across the United States and globally, including Canada, the U.K. and Europe, and moved to teleconference meetings only across the enterprise. As of the date of this report, the majority of our global workforce continues to work from home. The heightened security risks presented by widespread remote access to our computer systems, 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. For further discussion of risks associated with the operation of our business functions, facilities and systems and our vendors' facilities and systems, see the Risk Factor, “Any significant interruption in the operation of our business functions, facilities and systems or our vendors' facilities and systems could result in a materially adverse effect on our operations.” For further discussion of risks associated with information security, see the Risk Factor, “Any significant breach in our data security infrastructure could disrupt business, cause financial losses and damage our reputation.”
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, results of operations and financial condition, the extent of which cannot be determined with any certainty at this time. For further discussion of risks associated with vendors and third party service providers, see the Risk Factors, “Inability to detect and prevent significant employee or third party service provider misconduct, inadvertent errors and omissions, or exposure relating to functions performed on our behalf could result in a materially adverse effect on our business, results of operations and financial condition” and “Loss of key vendor relationships and issues relating to the transitioning of vendor relationships could compromise our ability to conduct business.”
Insurance Risks
If we determine that our recorded insurance reserves are insufficient to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, we may need to increase our insurance reserves which would result in a charge to our earnings.
We maintain insurance reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for reported and unreported claims. Insurance reserves are not an exact calculation of liability but instead are complex management estimates developed utilizing a variety of actuarial reserve estimation techniques as of a given reporting date. The reserve estimation process involves a high degree of judgment and variability and is subject to a number of factors which are highly uncertain. These variables can be affected by both changes in internal processes and external events. Key variables include frequency of claims, claim severity, mortality, morbidity, discount rates, inflation, claim handling policies and procedures, case reserving approach, underwriting and pricing policies, changes in the legal and regulatory environment and the lag time between the occurrence of an insured event and the time of its ultimate settlement. Mortality is the relative incidence of death. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted.
There is generally a higher degree of variability in estimating required reserves for long-tail coverages, such as workers' compensation, general liability and professional liability, as they require a relatively longer period of time for claims to be reported and settled. The impact of changes in inflation and medical costs are also more pronounced for long-tail coverages due to the longer settlement period. Certain risks and uncertainties associated with our insurance reserves are outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of MD&A in Item 7.
We are subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on our business, results of operations and financial condition
9

Table of Contents
by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims, resulting in further increases in our reserves. The effects of unforeseen emerging claim and coverage issues are extremely difficult to predict and may be material.
In light of the many uncertainties associated with establishing the estimates and making the judgments necessary to establish reserve levels, we continually review and change our reserve estimates in a regular and ongoing process as experience develops from the actual reporting and settlement of claims and as the legal, regulatory and economic environment evolves. If our recorded reserves are insufficient for any reason, the required increase in reserves would be recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges could be substantial.
Our actual experience could vary from the key assumptions used to determine active life reserves for long term care policies.
Our active life reserves for long term care policies are based on our best estimate assumptions as of September 30, 2020, due to a reserve unlocking at that date. Key assumptions include morbidity, persistency (the percentage of policies remaining in force), discount rate and future premium rate increases. Estimating future experience for long term care policies is highly uncertain because the adequacy of the reserves is contingent upon actual experience and our future expectations related to these key assumptions. If actual or expected future experience differs from these assumptions, the reserves may not be adequate, requiring us to add reserves. The required increase in reserves would be recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges could be substantial. See the Life & Group Policyholder Reserves portion of Reserves - Estimates and Uncertainties section of MD&A in Item 7 for more information.
Morbidity and persistency experience, inclusive of mortality, can be volatile and may be negatively affected by many factors including, but not limited to, policyholder behavior, judicial decisions regarding policy terms, socioeconomic factors, cost of care inflation, changes in health trends and advances in medical care.
A prolonged period during which investment returns remain at levels lower than those anticipated in our reserving would result in shortfalls in investment income on assets supporting our obligations under long term care policies, which may require changes to our reserves. This risk is more significant for our long term care products because the long potential duration of the policy obligations exceeds the duration of the supporting investment assets. Further, changes to the Internal Revenue Code may also affect the rate at which we discount our reserves. In addition, we may not receive regulatory approval for the level of premium rate increases we request. Any adverse deviation between the level of future premium rate increases approved and the level included in our reserving assumptions may require an increase to our reserves.
We are vulnerable to material losses from natural and man-made disasters.
Catastrophe losses are an inevitable part of our business. Various events can cause catastrophe losses. These events can be natural or man-made, and may include hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil unrest, cyber attacks, pandemics and acts of terrorism. The frequency and severity of these catastrophe events are inherently unpredictable. In addition, longer-term natural catastrophe trends may be changing and new types of catastrophe losses may be developing due to climate change, a phenomenon that has been associated with extreme weather events linked to rising temperatures and includes effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow.
The extent of our losses from catastrophes is a function of the total amount of our insured exposures in the affected areas, the frequency and severity of the events themselves, the level of reinsurance coverage, reinsurance reinstatement premiums and state residual market assessments, if any. It can take a long time for the ultimate cost of any catastrophe losses to us to be finally determined, as a multitude of factors contribute to such costs, including evaluation of general liability and pollution exposures, infrastructure disruption, business interruption and reinsurance collectibility. Further, significant catastrophic events or a series of catastrophic events have the potential to impose financial stress on the reinsurance industry, which could impact our ability to collect amounts owed to us by reinsurers, thereby resulting in higher net incurred losses.

Table of Contents
Reinsurance coverage for terrorism events is provided only in limited circumstances, especially in regard to “unconventional” terrorism acts, such as nuclear, biological, chemical or radiological attacks. Our principal reinsurance protection against these large-scale terrorist attacks is the coverage currently provided through TRIPRA through December 31, 2027. However, such coverage is subject to a mandatory deductible and other limitations. It is also possible that future legislation could change or eliminate the program, which could adversely affect our business by increasing our exposure to terrorism losses, or by lowering our business volume through efforts to avoid that exposure. For a further discussion of TRIPRA, see Part II, Item 7, MD&A - Catastrophes and Related Reinsurance.
As a result of the items discussed above, catastrophe losses are particularly difficult to estimate, could cause us to exhaust our available reinsurance limits and could adversely affect the cost and availability of reinsurance. Accordingly, catastrophic events could have a material adverse effect on our business, results of operations, financial condition and liquidity.
We have exposures related to asbestos and environmental pollution (A&EP) claims, which could result in material losses.
Our property and casualty insurance subsidiaries have exposures related to A&EP claims. Our experience has been that establishing claim and claim adjustment expense reserves for casualty coverages relating to A&EP claims is subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment expense reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability. On August 31, 2010, we completed a retroactive reinsurance transaction under which substantially all of our legacy A&EP liabilities were ceded to National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., subject to an aggregate limit of $4 billion (Loss Portfolio Transfer). The cumulative amount ceded under the Loss Portfolio Transfer as of December 31, 2020 is $3.3 billion. If the other parties to the Loss Portfolio Transfer do not fully perform their obligations, net losses incurred on A&EP claims covered by the Loss Portfolio Transfer exceed the aggregate limit of $4 billion, or we determine we have exposures to A&EP claims not covered by the Loss Portfolio Transfer, we may need to increase our recorded net reserves which would result in a charge against our earnings. These charges could be substantial. Additionally, if the A&EP claims exceed the limit of the Loss Portfolio Transfer, we will need to assess whether to purchase additional limit or to reassume claim handling responsibility for A&EP claims from an affiliate of NICO. Any additional reinsurance premium or future claim handling costs would also reduce our earnings.
We are exposed to, and may face adverse developments related to, mass tort claims that could arise from our insureds’ sale or use of potentially harmful products or substances, changes to the social and legal environment, issues related to altered interpretation of coverage and other new and emerging claim theories.
We face potential exposure to various types of new and emerging mass tort claims, including those related to exposure to potentially harmful products or substances such as glyphosate, lead paint and opioids; claims arising from changes that expand the right to sue, remove limitations on recovery, extend the statutes of limitations or otherwise repeal or weaken tort reforms, such as those related to abuse reviver statutes, including New York reviver statutes; and claims related to new and emerging theories of liability, such as those related to global warming and climate change. Evolving judicial interpretations and new legislation regarding the application of various tort theories and defenses, including application of various theories of joint and several liability, as well as the application of insurance coverage to these claims, give rise to new claimant activity. Emerging mass tort claim activity, including activity based on such changing judicial interpretations and recent and proposed legislation, could have a material adverse effect on our business, results of operations and financial condition.

Table of Contents
We may not be able to obtain sufficient reinsurance at a cost or on terms and conditions we deem acceptable, which could result in increased exposure to risk or a decrease in our underwriting commitments.
A primary reason we purchase reinsurance is to manage our exposure to risk. Under our ceded reinsurance arrangements, another insurer assumes a specified portion of our exposure in exchange for a specified portion of policy premiums. Market conditions determine the availability and cost of the reinsurance protection we purchase, which affects the level of our business and profitability, as well as the level and types of risk we retain. If we are unable to obtain sufficient reinsurance at a cost or on terms and conditions we deem acceptable, we may have increased exposure to risk, which could be material. Alternatively, we may be unwilling to bear the increased risk, which would reduce the level of our underwriting commitments.
Strategic Risks
We face intense competition in our industry; we may be adversely affected by the cyclical nature of the property and casualty business and the evolving landscape of our distribution network.
All aspects of the insurance industry are highly competitive and we must continuously allocate resources to refine and improve our insurance products and services to remain competitive. We compete with a large number of stock and mutual insurance companies and other entities, some of which may be larger or have greater financial or other resources than we do, for both distributors and customers. This includes agents, brokers and managing general underwriters who may increasingly compete with us to the extent that markets continue to provide them with direct access to providers of capital seeking exposure to insurance risk. Insurers compete on the basis of many factors, including products, price, services, ratings and financial strength. The competitor landscape has evolved substantially in recent years, with significant consolidation and new market entrants, such as insurtech firms, resulting in increased pressures on our ability to remain competitive, particularly in obtaining pricing that is both attractive to our customer base and risk-appropriate to us.
In addition, the property and casualty market is cyclical and has experienced periods characterized by relatively high levels of price competition, resulting in less restrictive underwriting standards and relatively low premium rates, followed by periods of relatively lower levels of competition, more selective underwriting standards and relatively high premium rates. During periods in which price competition is high, we may lose business to competitors offering competitive insurance products at lower prices. As a result, our premium levels and expense ratio could be materially adversely impacted.
We market our insurance products worldwide primarily through independent insurance agents, insurance brokers, and managing general underwriters who also promote and distribute the products of our competitors. Any change in our relationships with our distribution network agents, brokers or managing general underwriters, including as a result of consolidation and their increased promotion and distribution of our competitors' products, could adversely affect our ability to sell our products. As a result, our business volume and results of operations could be materially adversely impacted.
We may be adversely affected by technological changes or disruptions in the insurance marketplace.
Technological changes in the way insurance transactions are completed in the marketplace, and our ability to react effectively to such change, may present significant competitive risks. For example, more insurers are utilizing "big data" analytics to make underwriting and other decisions that impact product design and pricing. If such utilization is more effective than how we use similar data and information, we will be at a competitive disadvantage. There can be no assurance that we will continue to compete effectively with our industry peers due to technological changes; accordingly, this may have a material adverse effect on our business, results of operations and financial condition.
In addition, agents and brokers, technology companies, or other third parties may create alternate distribution channels for commercial business that may adversely impact product differentiation and pricing. For example, they may create a digitally enabled distribution channel that may adversely impact our competitive position. Our efforts or the efforts of agents and brokers with respect to new products or alternate distribution channels, as well as changes in the way agents and brokers utilize greater levels of data and technology, could adversely

impact our business relationship with independent agents and brokers who currently market our products, resulting in a lower volume and/or profitability of business generated from these sources.
We face considerable competition within our industry for qualified, specialized talent and any significant inability to attract and retain talent may adversely affect the execution of our business strategies.
The successful execution of our business plan depends on our ability to attract and retain qualified talent. Due to the intense competition in our industry and from businesses outside the industry for qualified employees, especially those in key positions and those possessing highly specialized knowledge and industry experience in areas such as underwriting, data and analytics and technology, we may encounter obstacles to our ability to attract and retain such employees, which could materially adversely affect our business, results of operations and financial condition.
We are controlled by a single stockholder which could result in potential conflicts of interest.
Loews beneficially owned approximately 89.6% of our outstanding shares of common stock as of December 31, 2020, and is in a position to control actions that require the consent of stockholders, including the election of directors, amendment of our Restated Certificate of Incorporation and any merger or sale of substantially all of our assets. In addition, five officers of Loews currently serve on our Board of Directors. We have also entered into services agreements and a registration rights agreement with Loews, and we may in the future enter into other agreements with Loews.  It is possible that potential conflicts of interest could arise in the future for our directors who are also officers of Loews with respect to a number of areas relating to the past and ongoing relationships of Loews and us, including tax and insurance matters, financial commitments and sales of common stock pursuant to registration rights or otherwise.
Financial Risks
We may incur significant realized and unrealized investment losses and volatility in net investment income arising from changes in the financial markets.
Our investment portfolio is exposed to various risks, such as interest rate, credit spread, issuer default, equity prices and foreign currency, which are unpredictable. Financial markets are highly sensitive to changes in economic conditions, monetary policies, tax policies, domestic and international geopolitical issues and many other factors. Changes in financial markets including fluctuations in interest rates, credit, equity prices and foreign currency prices and many other factors beyond our control can adversely affect the value of our investments, the realization of investment income and the rate at which we discount certain liabilities. Our investment portfolio is also subject to increased valuation uncertainties when investment markets are illiquid. The valuation of investments is more subjective when markets are illiquid, thereby increasing the risk that the estimated fair value (i.e., the carrying amount) of the portion of our investment portfolio that is carried at fair value in our financial statements is not reflective of the prices at which actual transactions could occur.
We have significant holdings in fixed maturity investments that are sensitive to changes in interest rates. A decline in interest rates may reduce the returns earned on new fixed maturity investments, thereby reducing our net investment income, while an increase in interest rates may reduce the value of our existing fixed maturity investments, which could reduce our net unrealized gains included in Accumulated other comprehensive income (AOCI). The value of our fixed maturity investments is also 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.
In addition, we invest a portion of our assets in limited partnerships and common stock which are subject to greater market volatility than our fixed maturity investments. Limited partnership investments generally provide a lower level of liquidity than fixed maturity or equity investments which may also limit our ability to withdraw funds from these investments. The timing and amount of income or losses on such investments is inherently variable and can contribute to volatility in reported earnings.
Further, we hold a portfolio of commercial mortgage loans. We are subject to risk related to the recoverability of loan balances, which is influenced by declines in the estimated cash flows from underlying property leases, fair value of collateral, refinancing risk and the creditworthiness of tenants of credit tenant loan properties,
13

where lease payments directly service the loan. Any changes in actual or expected collections would result in a charge to earnings.
As a result of these factors, we may not earn an adequate return on our investments, may be required to write-down the value of our investments and may incur losses on the disposition of our investments all of which could materially adversely affect our business, results of operations and financial condition.
Operational Risks
We use analytical models to assist our decision making in key areas such as pricing, reserving and capital modeling and may be adversely affected if actual results differ materially from the model outputs and related analyses.
We use various modeling techniques and data analytics (e.g., scenarios, predictive, stochastic and/or forecasting) to analyze and estimate exposures, loss trends and other risks associated with our assets and liabilities. This includes both proprietary and third party modeled outputs and related analyses to assist us in decision-making related to underwriting, pricing, capital allocation, reserving, investing, reinsurance and catastrophe risk, among other things. We incorporate numerous assumptions and forecasts about the future level and variability of policyholder behavior, loss frequency and severity, interest rates, equity markets, inflation, capital requirements, and currency exchange rates, among others. The modeled outputs and related analyses from both proprietary models and third parties are subject to various assumptions, uncertainties, model design errors and the inherent limitations of any statistical analysis. Further, climate change may make modeled outcomes less certain or produce new, non-modeled risks.
In addition, the effectiveness of any model can be degraded by operational risks, including the improper use of the model, input errors, data errors and human error. As a result, actual results may differ materially from our modeled results. The profitability and financial condition of the Company substantially depends on the extent to which our actual experience is consistent with assumptions we use in our models and ultimate model outputs. If, based upon these models or other factors, we misprice our products or fail to appropriately estimate the risks we are exposed to, our business, results of operations and financial condition may be materially adversely affected.
Any significant interruption in the operation of our business functions, facilities and systems or our vendors' facilities and systems could result in a materially adverse effect on our operations.
Our business is highly dependent upon our ability to perform, in an efficient and uninterrupted manner, through our employees or vendor relationships, necessary business functions (such as internet support and 24-hour call centers), processing new and renewal business and processing and paying claims and other obligations. Our or our vendors' facilities and systems could become unavailable, inoperable, or otherwise impaired from a variety of causes, including natural events, such as hurricanes, tornadoes, windstorms, earthquakes, severe winter weather and fires, or other events, such as explosions, terrorist attacks, computer security breaches or 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. 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 any reason could significantly impair our ability to perform critical business functions on a timely basis. In addition, because our information technology and telecommunications systems interface with and depend on third-party systems, we could experience service denials if demand for such service exceeds capacity or a third-party system fails or experiences an interruption. If sustained or repeated, such events could result in a deterioration of our ability to write and process new and renewal business, provide customer service, pay claims in a timely manner, or perform other necessary business functions, including the ability to issue financial statements in a timely manner.
The foregoing risks could expose us to monetary and reputational damages. Potential exposures include substantially increased compliance costs and required computer system upgrades and security-related

Table of Contents
investments. If our business continuity plans or system security does not sufficiently address these risks, they could have a material adverse effect on our business, results of operations and financial condition.
Any significant breach in our data security infrastructure could disrupt business, cause financial losses and damage our reputation.
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. Such a breach could affect our data framework or cause a failure to protect the personal information of our customers, claimants or employees, or sensitive and confidential information regarding our business and may result in operational impairments and financial losses, as well as significant harm to our reputation. The risk of a breach could increase as vendors increasingly offer cloud-based software services rather than software services which can be run within our data centers or as we choose to move additional functions to the cloud.
The breach of confidential information also could give rise to legal liability and regulatory action under data protection and privacy laws, as well as evolving regulation in this regard. Any such legal or regulatory action could have a material adverse effect on our business, results of operations and financial condition.
Inability to detect and prevent significant employee or third party service provider misconduct, inadvertent errors and omissions, or exposure relating to functions performed on our behalf could result in a materially adverse effect on our business, results of operations and financial condition.
We may incur losses which arise from employees or third party service providers engaging in intentional, negligent or inadvertent misconduct, fraud, errors and omissions, failure to comply with internal guidelines, including with respect to underwriting authority, or failure to comply with regulatory requirements. Our or our third party service providers' controls may not be able to detect all possible circumstances of such non-compliant activity and the internal structures in place to prevent this activity may not be effective in all cases. Any losses relating to such non-compliant activity could adversely affect our business, results of operations and financial condition.
Portions of our insurance business is underwritten and serviced by third parties. With respect to underwriting, our contractual arrangements with third parties will typically grant them limited rights to write new and renewal policies, subject to contractual restrictions and obligations, including requiring them to underwrite within the terms of our licenses. Should these third parties issue policies that exceed these contractual restrictions, we could be deemed liable for such policies and subject to regulatory fines and penalties for any breach of licensing requirements. It is possible that in such circumstance we might not be fully indemnified for such third parties’ contractual breaches.
Additionally, we rely on certain third-party claims administrators, including the administrators of our long term care claims, to perform significant claim administration and claim adjudication functions. Any failure by such administrator to properly perform service functions may result in losses as a result of over-payment of claims, legal claims against us and adverse regulatory enforcement exposure.
We have also licensed certain systems from third parties. We cannot be certain that we will have access to these systems or that our information technology or application systems will continue to operate as intended.
These risks could adversely impact our reputation and client relationships and have a material adverse effect on our business, results of operations and financial condition.
Loss of key vendor relationships and issues relating to the transitioning of vendor relationships could compromise our ability to conduct business.
In the event that one or more of our vendors suffers a bankruptcy, is sold to another entity, sustains a significant business interruption or otherwise becomes unable to continue to provide products or services at the requisite level, we may be adversely affected. We may suffer operational impairments and financial losses associated with transferring business to a new vendor, assisting a vendor with rectifying operational difficulties, failure by vendors to properly perform service functions or assuming previously outsourced operations ourselves. Our inability to provide for appropriate servicing if a vendor becomes unable to fulfill its contractual obligations to
15

Table of Contents
us, either through transitioning to another service provider temporarily or permanently or assuming servicing internally, may have a materially adverse effect on our business, results of operations and financial condition.
We are subject to capital adequacy requirements and, if we are unable to maintain or raise sufficient capital to meet these requirements, regulatory agencies may restrict or prohibit us from operating our business.
Insurance companies such as ours are subject to capital adequacy standards set by regulators to help identify companies that merit further regulatory attention. In the U.S., these standards apply specified risk factors to various asset, premium and reserve components of our legal entity statutory basis of accounting financial statements. Current rules, including those promulgated by insurance regulators and specialized markets, such as Lloyd's, require companies to maintain statutory capital and surplus at a specified minimum level determined using the applicable jurisdiction's regulatory capital adequacy formula. If we do not meet these minimum requirements, we may be restricted or prohibited from operating our business in the applicable jurisdictions and specialized markets. If we are required to record a material charge against earnings in connection with a change in estimated insurance reserves or the occurrence of a catastrophic event, or if we incur significant losses related to our investment portfolio, which severely deteriorates our capital position, we may violate these minimum capital adequacy requirements unless we are able to raise sufficient additional capital. We may be limited in our ability to raise significant amounts of capital on favorable terms or at all.
The IAIS has adopted a common framework for the supervision of internationally active insurance groups and continues to develop a group basis Insurance Capital Standard (ICS). The NAIC is also developing a group capital standard that is intended to be comparable to the ICS. The development and adoption of these capital standards could increase our prescribed capital requirement, the level at which regulatory scrutiny intensifies, as well as significantly increase our cost of regulatory compliance.
Our insurance subsidiaries, upon whom we depend for dividends in order to fund our corporate obligations, are limited by insurance regulators in their ability to pay dividends.
We are a holding company and are dependent upon dividends, loans and other sources of cash from our subsidiaries in order to meet our obligations. Ordinary dividend payments, or dividends that do not require prior approval by the insurance subsidiaries' domiciliary insurance regulator, are generally limited to amounts determined by formulas that vary by jurisdiction. If we are restricted from paying or receiving intercompany dividends, by regulatory rule or otherwise, we may not be able to fund our corporate obligations and debt service requirements or pay our stockholders dividends from available cash. As a result, we would need to pursue other sources of capital which may be more expensive or may not be available at all.
Rating agencies may downgrade their ratings of us, thereby adversely affecting our ability to write insurance at competitive rates or at all and increasing our cost of capital.
Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries, as well as our public debt, are rated by rating agencies, including, A.M. Best Company (A.M. Best), Moody's Investors Service, Inc. (Moody's), Standard & Poor's (S&P) and Fitch Ratings, Inc. (Fitch). Ratings reflect the rating agency's opinions of an insurance company's or insurance holding company's financial strength, capital adequacy, enterprise risk management practices, operating performance, strategic position and ability to meet its obligations to policyholders and debt holders.
The rating agencies may take action to lower our ratings in the future as a result of any significant financial loss or changes in the methodology or criteria applied by the rating agencies. The severity of the impact on our business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of our insurance products to certain markets and the required collateralization of certain future payment obligations or reserves. Further, if one or more of our corporate debt ratings were downgraded, we may find it more difficult to access the capital markets and we may incur higher borrowing costs.
In addition, it is possible that a significant lowering of the corporate debt ratings of Loews by certain of the rating agencies could result in an adverse effect on our ratings, independent of any change in our circumstances.

For further discussion of our ratings, see the Ratings subsection within the Liquidity and Capital Resources section of MD&A in Item 7.
We are subject to extensive existing state, local, federal and foreign governmental regulations that restrict our ability to do business and generate revenues; additional regulation or significant modification to existing regulations or failure to comply with regulatory requirements may have a materially adverse effect on our business, results of operations and financial condition.
The insurance industry is subject to comprehensive and detailed regulation and supervision. Most insurance regulations are designed to protect the interests of our policyholders and third-party claimants, rather than our investors. Each jurisdiction in which we do business has established supervisory agencies that regulate the manner in which we do business. Any changes in regulation could impose significant burdens on us. In addition, the Lloyd's marketplace sets rules under which its members, including our Hardy syndicate, operate.
These rules and regulations relate to, among other things, the standards of solvency (including risk-based capital measures), government-supported backstops for certain catastrophic events (including terrorism), investment restrictions, accounting and reporting methodology, establishment of reserves and potential assessments of funds to settle covered claims against impaired, insolvent or failed private or quasi-governmental insurers.
Regulatory powers also extend to premium rate regulations which require that rates not be excessive, inadequate or unfairly discriminatory. State jurisdictions ensure compliance with such regulations through market conduct exams, which may result in losses to the extent non-compliance is ascertained, either as a result of failure to document transactions properly or failure to comply with internal guidelines, or otherwise. The jurisdictions in which we do business may also require us to provide coverage to persons whom we would not otherwise consider eligible or restrict us from withdrawing from unprofitable lines of business or unprofitable market areas. Each jurisdiction dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each jurisdiction.

Table of Contents
OVERVIEW
The following discussion should be read in conjunction with Item 1A Risk Factors, Item 6 Selected Financial Data and Item 8 Financial Statements and Supplementary Data of this Form 10-K.
CRITICAL ACCOUNTING ESTIMATES
The preparation of 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 Consolidated Financial Statements and the amount of revenues and expenses reported during the period. Actual results may differ from those estimates.
Our Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third-party professionals and various other assumptions that are believed to be reasonable under the known facts and circumstances.
The accounting estimates discussed below are considered by us to be critical to an understanding of our Consolidated Financial Statements as their application places the most significant demands on our judgment. Note A to the Consolidated Financial Statements included under Item 8 should be read in conjunction with this section to assist with obtaining an understanding of the underlying accounting policies related to these estimates. Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from 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.
Insurance Reserves
Insurance reserves are established for both short and long-duration insurance contracts. Short-duration contracts are primarily related to property and casualty insurance policies where the reserving process is based on actuarial estimates of the amount of loss, including amounts for known and unknown claims. Long-duration contracts are primarily related to long term care policies and are estimated using actuarial estimates about morbidity and persistency as well as assumptions about expected investment returns and future premium rate increases. The reserve for unearned premiums represents the portion of premiums written related to the unexpired terms of coverage. The reserving process is discussed in further detail in the Reserves-Estimates and Uncertainties section below.
Long Term Care Reserves
Future policy benefit reserves for our long term care policies are based on certain assumptions, including morbidity, persistency, inclusive of mortality, discount rates and future premium rate increases. The adequacy of the reserves is contingent upon actual experience and our future expectations related to these key assumptions. If actual or expected future experience differs from these assumptions, the reserves may not be adequate, requiring us to add to reserves.
A prolonged period during which investment returns remain at levels lower than those anticipated in our reserving discount rate assumption could result in shortfalls in investment income on assets supporting our obligations under long term care policies, which may also require an increase to our reserves. In addition, we may not receive regulatory approval for the level of premium rate increases we request.
These changes to our reserves could materially adversely impact our results of operations, financial condition and equity. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.
Reinsurance and Insurance Receivables
Exposure exists with respect to the collectibility of ceded property and casualty and life reinsurance to the extent that any reinsurer is unable to meet its obligations or disputes the liabilities we have ceded under reinsurance agreements. An allowance for uncollectible reinsurance is recorded on the basis of periodic evaluations of balances due from reinsurers, reinsurer financial strength rating and solvency, industry

experience and current and forecast economic conditions. Further information on our reinsurance receivables is in Note G to the Consolidated Financial Statements included under Item 8.
Additionally, exposure exists with respect to the collectibility of amounts due from policyholders related to insurance contracts, including amounts due from insureds under high deductible policies and retrospectively rated policies. An allowance for uncollectible insurance receivables is recorded on the basis of periodic evaluations of balances due from insureds, currently as well as in the future, historical business default data, management's experience and current and forecast economic conditions.
If actual experience differs from the estimates made by management in determining the allowances for uncollectible reinsurance and insurance receivables, net receivables as reflected on our Consolidated Balance Sheets may not be collected. Therefore, our results of operations, financial condition or equity could be materially adversely affected. Further information on our process for determining the allowances for uncollectible reinsurance and insurance receivables is in Note A to the Consolidated Financial Statements included under Item 8.
Valuation of Investments and Impairment of Securities
Our fixed maturity and equity securities are carried at fair value on the balance sheet. Fair value represents the price that would be received in a sale of an asset in an orderly transaction between market participants on the measurement date, the determination of which may require us to make a significant number of assumptions and judgments. Securities with the greatest level of subjectivity around valuation are those that rely on inputs that are significant to the estimated fair value and that are not observable in the market or cannot be derived principally from or corroborated by observable market data. These unobservable inputs are based on assumptions consistent with what we believe other market participants would use to price such securities. Further information on our fair value measurements is in Note C to the Consolidated Financial Statements included under Item 8.
Our fixed maturity securities are subject to market declines below amortized cost that may result in the recognition of impairment losses in earnings. Factors considered in the determination of whether or not an impairment loss is recognized in earnings include a current intention or need to sell the security or an indication that a credit loss exists. Significant judgment is required in the determination of whether a credit loss has occurred for a security. We consider all available evidence when determining whether a security requires a credit allowance to be recorded, including the financial condition and expected near-term and long-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, industry, sector or other specific factors and whether we expect to receive cash flows sufficient to recover the entire amortized cost basis of the security.
Our mortgage loan portfolio is subject to the expected credit loss model, which requires immediate recognition of estimated credit losses over the life of the asset and the presentation of the asset at the net amount expected to be collected. Significant judgment is required in the determination of estimated credit losses and any changes in our expectation of the net amount to be collected are recognized in earnings.
Further information on our process for evaluating impairments and expected credit losses is in Note A to the Consolidated Financial Statements included under Item 8.
Income Taxes
We account for income taxes under the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial statement and tax return basis of assets and liabilities. Any resulting future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized. The assessment of the need for a valuation allowance requires management to make estimates and assumptions about future earnings, reversal of existing temporary differences and available tax planning strategies. If actual experience differs from these estimates and assumptions, the recorded deferred tax asset may not be fully realized resulting in an increase to income tax expense in our results of operations. In addition, the ability to record deferred tax assets in the future could be limited, resulting in a higher effective tax rate in that future period.

RESERVES - ESTIMATES AND UNCERTAINTIES
The level of claim reserves we maintain represents our best estimate, as of a particular point in time, of what the ultimate settlement and administration of claims will cost based on our assessment of facts and circumstances known at that time. Reserves are not an exact calculation of liability but instead are complex estimates that we derive, generally utilizing a variety of actuarial reserve estimation techniques, from numerous assumptions and expectations about future events, both internal and external, many of which are highly uncertain. As noted below, we review our reserves for each segment of our business periodically, and any such review could result in the need to increase reserves in amounts which could be material and could adversely affect our results of operations, financial condition, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note E to the Consolidated Financial Statements included under Item 8.
Property and Casualty Claim and Claim Adjustment Expense Reserves
We maintain loss reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for claims that have been reported but not yet settled (case reserves) and claims that have been incurred but not reported (IBNR). IBNR includes a provision for development on known cases as well as a provision for late reported incurred claims. Claim and claim adjustment expense reserves are reflected as liabilities and are included on the Consolidated Balance Sheets under the heading “Insurance Reserves.” Adjustments to prior year reserve estimates, if necessary, are reflected in results of operations in the period that the need for such adjustments is determined. The carried case and IBNR reserves as of each balance sheet date are provided in the Segment Results section of this MD&A and in Note E to the Consolidated Financial Statements included under Item 8.
As discussed in the Risk Factors discussion within Item 1A, there is a risk that our recorded reserves are insufficient to cover our estimated ultimate unpaid liability for claims and claim adjustment expenses. Given the unprecedented nature of the event, a particularly high level of uncertainty exists as to the potential impact on insurance losses related to the COVID-19 pandemic, mitigating actions and consequent economic crisis. Unforeseen emerging or potential claims and coverage issues are also difficult to predict and could materially adversely affect the adequacy of our claim and claim adjustment expense reserves and could lead to future reserve additions.
In addition, our property and casualty insurance subsidiaries also have actual and potential exposures related to A&EP claims, which could result in material losses. To mitigate the risks posed by our exposure to A&EP claims and claim adjustment expenses, we completed a transaction with NICO under which substantially all of our legacy A&EP liabilities were ceded to NICO effective January 1, 2010. See Note E to the Consolidated Financial Statements included under Item 8 for further discussion about the transaction with NICO, its impact on our results of operations, the deferred retroactive reinsurance gain and the amount of remaining reinsurance limit.
Establishing Property & Casualty Reserve Estimates
In developing claim and claim adjustment expense (loss or losses) reserve estimates, our actuaries perform detailed reserve analyses that are staggered throughout the year. The data is organized at a reserve group level. A reserve group can be a line of business covering a subset of insureds such as commercial automobile liability for small or middle market customers or it can be a particular type of claim such as construction defect. Every reserve group is reviewed at least once during the year, but most are reviewed more frequently. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. In addition to the detailed analyses, we review actual loss emergence for all products each quarter.
Most of our business can be characterized as long-tail. For long-tail business, it will generally be several years between the time the business is written and the time when all claims are settled. Our long-tail exposures include commercial automobile liability, workers' compensation, general liability, medical professional liability, other professional liability and management liability coverages, assumed reinsurance run-off and products liability. Short-tail exposures include property, commercial automobile physical damage, marine, surety and

warranty. Specialty, Commercial and International contain both long-tail and short-tail exposures. Corporate & Other contains run-off long-tail exposures.
Various methods are used to project ultimate losses for both long-tail and short-tail exposures.
The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident or policy years with further expected changes in paid losses. Selection of the paid loss pattern may require consideration of several factors, including the impact of inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions and legislative changes, the impact of underwriting changes, the impact of large claim payments and other factors. Claim cost inflation itself may require evaluation of changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement and the impact of judicial decisions, legislative changes and other factors. Because this method assumes that losses are paid at a consistent rate, changes in any of these factors can affect the results. Since the method does not rely on case reserves, it is not directly influenced by changes in their adequacy.
For many reserve groups, paid loss data for recent periods may be too immature or erratic for accurate predictions. This situation often exists for long-tail exposures. In addition, changes in the factors described above may result in inconsistent payment patterns. Finally, estimating the paid loss pattern subsequent to the most mature point available in the data analyzed often involves considerable uncertainty for long-tail products such as workers' compensation.
The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses.  Since the method uses more data (case reserves in addition to paid losses) than the paid development method, the incurred development patterns may be less variable than paid patterns. However, selection of the incurred loss pattern typically requires analysis of all of the same factors described above. In addition, the inclusion of case reserves can lead to distortions if changes in case reserving practices have taken place, and the use of case incurred losses may not eliminate the issues associated with estimating the incurred loss pattern subsequent to the most mature point available.
The loss ratio method multiplies earned premiums by an expected loss ratio to produce ultimate loss estimates for each accident or policy year. This method may be useful for immature accident or policy periods or if loss development patterns are inconsistent, losses emerge very slowly or there is relatively little loss history from which to estimate future losses. The selection of the expected loss ratio typically requires analysis of loss ratios from earlier accident or policy years or pricing studies and analysis of inflationary trends, frequency trends, rate changes, underwriting changes and other applicable factors.
The Bornhuetter-Ferguson method using paid loss is a combination of the paid development method and the loss ratio method. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method and typically requires analysis of the same factors described above. This method assumes that future losses will develop at the expected loss ratio level. The percent of paid loss to ultimate loss implied from the paid development method is used to determine what percentage of ultimate loss is yet to be paid. The use of the pattern from the paid development method typically requires consideration of the same factors listed in the description of the paid development method. The estimate of losses yet to be paid is added to current paid losses to estimate the ultimate loss for each year. For long-tail lines, this method will react very slowly if actual ultimate loss ratios are different from expectations due to changes not accounted for by the expected loss ratio calculation.
The Bornhuetter-Ferguson method using incurred loss is similar to the Bornhuetter-Ferguson method using paid loss except that it uses case incurred losses. The use of case incurred losses instead of paid losses can result in development patterns that are less variable than paid patterns. However, the inclusion of case reserves can lead to distortions if changes in case reserving have taken place, and the method typically requires analysis of the same factors that need to be reviewed for the loss ratio and incurred development methods.
The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident or policy year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for reserve groups where loss development patterns are inconsistent or too variable to be relied

on exclusively. In addition, this method can more directly account for changes in coverage that affect the number and size of claims. However, this method can be difficult to apply to situations where very large claims or a substantial number of unusual claims result in volatile average claim sizes. Projecting the ultimate number of claims may require analysis of several factors, including the rate at which policyholders report claims to us, the impact of judicial decisions, the impact of underwriting changes and other factors. Estimating the ultimate average loss may require analysis of the impact of large losses and claim cost trends based on changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors.
Stochastic modeling produces a range of possible outcomes based on varying assumptions related to the particular reserve group being modeled. For some reserve groups, we use models which rely on historical development patterns at an aggregate level, while other reserve groups are modeled using individual claim variability assumptions supplied by the claims department. In either case, multiple simulations using varying assumptions are run and the results are analyzed to produce a range of potential outcomes. The results will typically include a mean and percentiles of the possible reserve distribution which aid in the selection of a point estimate.
For many exposures, especially those that are considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, our actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method.  For most of our products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, we may not assign much, if any, weight to the paid and incurred development methods. We may use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods.  For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because our history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, we may also use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods for short-tail exposures.
For other more complex reserve groups where the above methods may not produce reliable indications, we use additional methods tailored to the characteristics of the specific situation.
Periodic Reserve Reviews
The reserve analyses performed by our actuaries result in point estimates. Each quarter, the results of the detailed reserve reviews are summarized and discussed with senior management to determine management's best estimate of reserves. Senior management considers many factors in making this decision. Our recorded reserves reflect our best estimate as of a particular point in time based upon known facts and circumstances, consideration of the factors cited above and our judgment. The carried reserves differ from the actuarial point estimate as discussed further below.
Currently, our recorded reserves are modestly higher than the actuarial point estimate. For Commercial, Specialty and International, the difference between our reserves and the actuarial point estimate is primarily driven by uncertainty with respect to immature accident years, claim cost inflation, changes in claims handling, changes to the tort environment which may adversely affect claim costs and the effects from the economy. For Corporate & Other, the difference between our reserves and the actuarial point estimate is primarily driven by the potential tail volatility of run-off exposures.
The key assumptions fundamental to the reserving process are often different for various reserve groups and accident or policy years. Some of these assumptions are explicit assumptions that are required of a particular method, but most of the assumptions are implicit and cannot be precisely quantified. An example of an explicit assumption is the pattern employed in the paid development method. However, the assumed pattern is itself based on several implicit assumptions such as the impact of inflation on medical costs and the rate at which claim professionals close claims. As a result, the effect on reserve estimates of a particular change in assumptions typically cannot be specifically quantified, and changes in these assumptions cannot be tracked over time.

Our recorded reserves are management's best estimate. In order to provide an indication of the variability associated with our net reserves, the following discussion provides a sensitivity analysis that shows the approximate estimated impact of variations in significant factors affecting our reserve estimates for particular types of business. These significant factors are the ones that we believe could most likely materially affect the reserves. This discussion covers the major types of business for which we believe a material deviation to our reserves is reasonably possible. There can be no assurance that actual experience will be consistent with the current assumptions or with the variation indicated by the discussion. In addition, there can be no assurance that other factors and assumptions will not have a material impact on our reserves.
The three areas for which we believe a significant deviation to our net reserves is reasonably possible are (i) professional liability, management liability and surety products; (ii) workers' compensation; and (iii) general liability.
Professional liability, management liability and surety products include U.S. professional liability coverages provided to various professional firms, including architects, real estate agents, small and mid-sized accounting firms, law firms and other professional firms. They also include directors and officers (D&O), employment practices, fiduciary, fidelity and surety coverages, and medical liability. The most significant factor affecting reserve estimates for these liability coverages is claim severity. Claim severity is driven by the cost of medical care, the cost of wage replacement, legal fees, judicial decisions, legislative changes and other factors. Underwriting and claim handling decisions, such as the classes of business written and individual claim settlement decisions, can also affect claim severity. If the estimated claim severity increases by 9%, we estimate that net reserves would increase by approximately $400 million. If the estimated claim severity decreases by 3%, we estimate that net reserves would decrease by approximately $150 million. Our net reserves for these products were approximately $4.6 billion as of December 31, 2020.
For workers' compensation, since many years will pass from the time the business is written until all claim payments have been made, the most significant factor affecting workers' compensation reserve estimates is claim cost inflation on claim payments. Workers' compensation claim cost inflation is driven by the cost of medical care, the cost of wage replacement, expected claimant lifetimes, judicial decisions, legislative changes and other factors. If estimated workers' compensation claim cost inflation increases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would increase by approximately $350 million. If estimated workers' compensation claim cost inflation decreases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would decrease by approximately $350 million. Our net reserves for workers' compensation were approximately $3.9 billion as of December 31, 2020.
For general liability, the most significant factor affecting reserve estimates is claim severity. Claim severity is driven by changes in the cost of repairing or replacing property, the cost of medical care, the cost of wage replacement, judicial decisions, legislation and other factors. If the estimated claim severity for general liability increases by 6%, we estimate that our net reserves would increase by approximately $200 million. If the estimated claim severity for general liability decreases by 3%, we estimate that our net reserves would decrease by approximately $100 million. Our net reserves for general liability were approximately $3.5 billion as of December 31, 2020.
Given the factors described above, it is not possible to quantify precisely the ultimate exposure represented by claims and related litigation. As a result, we regularly review the adequacy of our reserves and reassess our reserve estimates as historical loss experience develops, additional claims are reported and settled and additional information becomes available in subsequent periods. In reviewing our reserve estimates, we make adjustments in the period that the need for such adjustments is determined. These reviews have resulted in our identification of information and trends that have caused us to change our reserves in prior periods and could lead to our identification of a need for additional material increases or decreases in claim and claim adjustment expense reserves, which could materially affect our results of operations, financial condition, equity, business and insurer financial strength and corporate debt ratings, positively or negatively. See discussion within Note E to the Consolidated Financial Statements included under Item 8 for additional information about reserve development and the Ratings section of this MD&A for further information regarding our financial strength and corporate debt ratings.

Life & Group Policyholder Reserves
Our Life & Group segment includes our run-off long term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long term care policies provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and we have the ability to increase policy premiums, subject to state regulatory approval.
We maintain both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for our 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 our long term care policies, our actuaries perform a detailed claim reserve review on an annual basis. The review analyzes the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. In addition, claim and claim adjustment expense reserves are also maintained for the structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for our structured settlement obligations, our actuaries monitor mortality experience on an annual basis. Our recorded claim and claim adjustment expense reserves reflect management's best estimate after incorporating the results of the most recent reviews. Claim and claim adjustment expense reserves for long term care policies and structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.
Future policy benefit reserves consist of the active life reserves related to our long term care policies for policyholders that are not currently receiving benefits and represent the present value of expected future benefit payments and expenses less expected future premium. The determination of these reserves requires management to make estimates and assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk.
The actuarial assumptions that management believes are subject to the most variability are morbidity, persistency, discount rates and anticipated future premium rate increases. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Discount rates are influenced by the investment yield on assets supporting long term care reserves which is subject to interest rate and market volatility and may also be affected by changes to the Internal Revenue Code. Future premium rate increases are generally subject to regulatory approval, and therefore the exact timing and size of the approved rate increases are unknown. As a result of this variability, our long term care reserves may be subject to material increases if actual experience develops adversely to our expectations.
Annually, in the third quarter, management assesses the adequacy of its long term care future policy benefit reserves by performing a gross premium valuation (GPV) to determine if there is a premium deficiency. Under the GPV, management estimates required reserves using best estimate assumptions as of the date of the assessment without provisions for adverse deviation. The GPV required reserves are then compared to the existing recorded reserves. If the GPV required reserves are greater than the existing recorded reserves, the assumptions are unlocked and future policy benefit reserves are increased to the greater amount. Any such increase is reflected in our 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.

The September 30, 2020 GPV indicated a premium deficiency of $74 million and future policy benefit reserves were increased accordingly. As a result, the long term care active life reserves carried as of September 30, 2020 represent management's best estimate assumptions at that date with no margin for adverse deviation. A summary of the changes as a result of the 2020 GPV is presented in the table below:
Long Term Care Active Life Reserve - Change in estimated reserve margin (In millions)
September 30, 2019 Estimated Margin$— 
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 are not establishing 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.

CATASTROPHES AND RELATED REINSURANCE
Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil unrest, cyber attacks, pandemics and acts of terrorism that produce unusually large aggregate losses. In most, but not all cases, our catastrophe losses from these events in the U.S. are defined consistent with the definition of the Property Claims Service (PCS). PCS defines a catastrophe as an event that causes damage of $25 million or more in direct insured losses to property and affects a significant number of policyholders and insurers. For events outside of the U.S., we define a catastrophe as an industry recognized event that generates an accumulation of claims amounting to more than $1 million for the International segment.
Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in our results of operations and/or equity. We reported catastrophe losses, net of reinsurance, of $550 million and $179 million for the years ended December 31, 2020 and 2019. Net catastrophe losses for the year ended December 31, 2020 included $294 million related primarily to severe weather related events, $195 million related to the COVID-19 pandemic and $61 million related to civil unrest. Net catastrophe losses for the year ended December 31, 2019 related primarily to U.S. weather related events.
We generally seek to manage our exposure to catastrophes through the purchase of catastrophe reinsurance and have catastrophe reinsurance treaties that cover property and workers’ compensation losses. We conduct an ongoing review of our risk and catastrophe coverages and from time to time make changes as we deem appropriate. The following discussion summarizes our most significant catastrophe reinsurance coverage at January 1, 2021.
Group North American Property Treaty
We purchased corporate catastrophe excess-of-loss treaty reinsurance covering our U.S. states and territories and Canadian property exposures underwritten in our North American and European companies. Exposures underwritten through Hardy are excluded. The treaty has a term of May 1, 2020 to May 1, 2021 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $250 million up to $1.2 billion. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological or chemical attack. All layers of the treaty provide for one full reinstatement.
Group Workers' Compensation Treaty
We also purchased corporate Workers' Compensation catastrophe excess-of-loss treaty reinsurance for the period January 1, 2021 to January 1, 2022 providing $275 million of coverage for the accumulation of covered losses related to natural catastrophes above our per occurrence retention of $25 million. The treaty also provides $475 million of coverage for the accumulation of covered losses related to terrorism events above our retention of $25 million. Of this $475 million in Terrorism coverage, $200 million is provided for nuclear, biological chemical and radiation events. One full reinstatement is available for the first $275 million above the retention, regardless of the covered peril. We also purchased a targeted facultative facility to address exposure accumulations in specific peak Terrorism zones.
Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA)
Our principal reinsurance protection against large-scale terrorist attacks, including nuclear, biological, chemical or radiological attacks, is the coverage currently provided through TRIPRA which runs through the end of 2027. TRIPRA provides a U.S. government backstop for insurance-related losses resulting from any “act of terrorism”, which is certified by the Secretary of Treasury in consultation with the Secretary of Homeland Security for losses that exceed a threshold of $200 million industry-wide for the calendar year 2021. Under the current provisions of the program, in 2021, the federal government will reimburse 80% of our covered losses in excess of our applicable deductible up to a total industry program cap of $100 billion. Our deductible is based on eligible commercial property and casualty earned premiums for the preceding calendar year. Based on 2020 earned premiums, our estimated deductible under the program is $820 million for 2021. If an act of terrorism or acts of terrorism result in covered losses exceeding the $100 billion annual industry aggregate limit, Congress would be responsible for determining how additional losses in excess of $100 billion will be paid.

CONSOLIDATED OPERATIONS
Results of Operations
In March 2020, 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. These conditions had a significant impact across our enterprise during 2020. During the first quarter of 2020 we experienced significant declines in the value of our investment portfolio. While financial markets broadly recovered by the end of 2020, our Net investment income and Net investment gains (losses) are lower for the year ended December 31, 2020 as compared with 2019. We also recorded significant catastrophe losses during 2020 related to COVID-19 and recorded a reduction in our estimated audit premiums due to lower exposure. Our 2020 consolidated financial statements reflect our best estimate of the impacts related to COVID-19. While we currently believe that the predominant financial impacts of the pandemic and related mitigating efforts have been incurred as of December 31, 2020, given the unprecedented nature of this event, a high level of uncertainty remains as to future effects. The scope, duration and magnitude of the pandemic and its direct and indirect effects could continue to evolve, and could materially adversely impact our business, results of operations and financial condition.

For a further discussion of the risks to our business associated with COVID-19, see the Risk Factor included under Part I, Item 1A of this Form 10-K.

For more detailed components of our business operations and a discussion of the core income (loss) financial measure, see the Segment Results section within this MD&A. For further discussion of Net investment income and Net investment gains or losses, see the Investments section of this MD&A.

2020 Compared with 2019
Core income decreased $244 million in 2020 as compared with 2019. Core income for our Property & Casualty Operations decreased $356 million primarily due to higher net catastrophe losses and lower net investment income partially offset by improved non-catastrophe current accident year underwriting results. Core results for our Life & Group segment improved $118 million. Life & Group results for the year ended December 31, 2020 include a $59 million charge related to recognition of a premium deficiency as a result of the third quarter 2020 GPV compared to a $170 million charge in 2019 related to recognition of a premium deficiency as a result of the third quarter 2019 GPV. Core loss for our Corporate & Other segment increased $6 million.
Net catastrophe losses were $550 million in 2020 as compared with $179 million in 2019. Catastrophe losses for the year ended December 31, 2020 include $294 million related primarily to severe weather related events, $195 million related to COVID-19 and $61 million related to civil unrest. The COVID-19 losses represent our best estimate of ultimate insurance losses and loss adjustment expenses, including defense costs resulting from the pandemic, mitigating actions 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 related to COVID-19, 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 premium receivables resulting from depressed economic conditions.
Favorable net prior year loss reserve development of $20 million and $73 million was recorded in 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 Consolidated Financial Statements included under Item 8.

SEGMENT RESULTS
The following discusses the results of operations for our business segments.
Our property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International, which we refer to collectively as Property & Casualty Operations. Specialty provides management and professional liability and other coverages through property and casualty products and services using a network of brokers, independent agencies and managing general underwriters. Commercial works with a network of brokers and independent agents to market a broad range of property and casualty insurance products to all types of insureds targeting small business, construction, middle markets and other commercial customers. The International segment underwrites property and casualty coverages on a global basis through a branch operation in Canada, a European business consisting of two insurance companies based in the U.K. and Luxembourg and Hardy, our Lloyd's syndicate.
Our operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other. Life & Group primarily includes the results of our long term care business that is in run-off. Corporate & Other primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty businesses in run-off, including CNA Re and A&EP. Intersegment eliminations are also included in this segment.
On December 30, 2020, we entered into an agreement with Cavello Bay Reinsurance Limited (Cavello), a subsidiary of Enstar Group Limited, under which Cavello will reinsure a legacy portfolio of excess workers’ compensation policies. The transaction closed on February 5, 2021 and is based on reserves in place as of January 1, 2020, and adjusted for any subsequent claim activity. We will reclassify this business from the Commercial segment to the Corporate & Other segment, better reflecting the manner in which we are organized for purposes of making operating decisions and assessing performance. The new classifications will be presented in our financial statements beginning with the period ending March 31, 2021, and prior periods presented will conform to the new presentation. Further information on this retroactive reinsurance agreement is provided in Note S to the Consolidated Financial Statements included under Item 8.
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 and reconciliations of non-GAAP measures to the most comparable GAAP measures and other information in Note O to the Consolidated Financial Statements included under Item 8.
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 Consolidated Financial Statements included under Item 8.

2020 Compared with 2019
Gross written premiums, excluding third party captives, for Specialty increased $281 million in 2020 as compared with 2019 driven by strong rate and higher new business. Net written premiums for Specialty increased $192 million in 2020 as compared with 2019. The increase in net earned premiums was consistent with the trend in net written premiums.
Core income decreased $136 million in 2020 as compared with 2019 primarily due to higher net catastrophe losses and lower net investment income partially offset by improved non-catastrophe current accident year underwriting results.
The combined ratio of 93.5% increased 3.3 points in 2020 as compared with 2019 primarily due to a 4.6 point increase in the loss ratio partially offset by a 1.2 point improvement in the expense ratio. The increase in the loss ratio was primarily due to higher net catastrophe losses. Net catastrophe losses were $125 million, or 4.3 points of the loss ratio, for 2020, as compared with $15 million, or 0.5 points of the loss ratio, for 2019. Net catastrophe losses in 2020 included $109 million related to the COVID-19 pandemic and $16 million related primarily to severe weather related events. The improvement in the expense ratio was driven by lower underwriting expenses and higher net earned premiums.
Favorable net prior year loss reserve development of $61 million and $92 million was recorded in 2020 and 2019. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2020 Compared with 2019
Gross written premiums for Commercial increased $393 million in 2020 as compared with 2019 driven by strong rate and higher new business. Net written premiums for Commercial increased $250 million in 2020 as compared with 2019. The increase in net earned premiums was consistent with the trend in net written premiums partially offset by a reduction in estimated audit premiums as a result of the economic slowdown arising from COVID-19 and premium rate adjustments impacting certain general liability policies. Further information on the general liability premium rate adjustments is provided in Note F to the Consolidated Financial Statements included under Item 8.
Core income decreased $228 million in 2020 as compared with 2019, primarily due to higher net catastrophe losses, lower net investment income and unfavorable net prior year loss reserve development in the current year, including a $50 million charge for mass tort exposures primarily due to New York reviver statute-related claims. These results were partially offset by improved non-catastrophe current accident year underwriting results.
The combined ratio of 106.9% increased 6.1 points in 2020 as compared with 2019 due to an increase in the loss ratio. The increase in the loss ratio was driven by higher net catastrophe losses and unfavorable net prior

year loss reserve development. Net catastrophe losses were $358 million, or 10.7 points of the loss ratio, for 2020, as compared with $154 million, or 4.9 points of the loss ratio, for 2019. Net catastrophe losses in 2020 included $252 million related primarily to severe weather related events, $58 million related to civil unrest and $48 million related to the COVID-19 pandemic. The expense ratio in 2020 was consistent with 2019 as higher acquisition expenses were offset by higher net earned premiums and lower underwriting expenses.
Unfavorable net prior year loss reserve development of $43 million was recorded in 2020 as compared with favorable development of $2 million in 2019. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2020 Compared with 2019
Gross written premiums for International increased $22 million in 2020 as compared with 2019 driven by growth in Europe and Canada partially offset by the impact of the strategic exit from certain Lloyd’s business classes. Net written premiums for International decreased $10 million in 2020 as compared with 2019. The decrease in net earned premiums was consistent with the trend in net written premiums.
Core income increased $8 million in 2020 as compared with 2019.
The combined ratio of 102.4% increased 0.6 points in 2020 as compared with 2019 due to a 2.8 point increase in the loss ratio partially offset by a 2.2 point improvement in the expense ratio. The increase in the loss ratio was driven by higher net catastrophe losses partially offset by favorable net prior year loss reserve development in the current year. Net catastrophe losses were $67 million, or 7.1 points of the loss ratio, for 2020, as compared with $10 million, or 1.1 points of the loss ratio, for 2019. Net catastrophe losses in 2020 included $38 million related to the COVID-19 pandemic, $26 million related primarily to severe weather related events

and $3 million related to civil unrest. The improvement in the expense ratio was driven by lower acquisition and underwriting expenses.
Favorable net prior year loss reserve development of $2 million was recorded in 2020 as compared with unfavorable net prior year loss reserve development of $21 million in 2019. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2020 Compared with 2019
Core results improved $118 million in 2020 as compared with 2019.
Core income for 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 income for 2020 also included a $36 million charge related to an increase in the structured settlement claim reserves and a $30 million benefit related to a reduction in long term care claim reserves, both resulting from the annual claim reserve reviews in the third quarter of 2020. Core loss for 2019 included a $170 million charge related to the recognition of an active life reserve premium deficiency and a $44 million benefit related to a reduction in long term care claim reserves resulting from the annual claim reserve reviews in the third quarter of 2019.
Excluding the impacts of the GPV and claim reserve reviews, core results in 2020 were favorable driven by better than expected morbidity in the long term care business and higher net investment income. The increase in net investment income was driven by the allocation of a portion of limited partnership income to the Life & Group segment beginning in the fourth quarter of 2020. Further, during 2020, relative to expectations, we experienced lower new claim frequency, higher claim terminations and more favorable claim severity 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.

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.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our primary operating cash flow sources are premiums and investment income. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.
For 2020, net cash provided by operating activities was $1,775 million as compared with $1,140 million for 2019. The increase in cash provided by operating activities was driven by an increase in premiums collected, lower net claim payments and lower income taxes paid, partially offset by a lower level of distributions from limited partnerships.
Cash flows from investing activities include the purchase and disposition of financial instruments, excluding those held as trading, and may include the purchase and sale of businesses, equipment and other assets not generally held for resale.
Net cash used by investing activities was $705 million for 2020, as compared with $225 million for 2019. Net cash used by investing activities is primarily driven by cash available from operations and by other factors, such as financing activities.
Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, and outflows for stockholder dividends, repayment of debt and purchases of treasury stock.
Net cash used by financing activities was $902 million and $988 million for 2020 and 2019. Financing activities for the periods presented include:
In 2020, we paid dividends of $950 million and repurchased 435,376 shares of our common stock at an aggregate cost of $18 million.
In the third quarter of 2020, we issued $500 million of 2.05% senior notes due August 15, 2030 and redeemed the $400 million outstanding aggregate principal balance of our 5.75% senior notes due August 15, 2021.
In 2019, we paid dividends of $929 million and repurchased 527,454 shares of our common stock at an aggregate cost of $23 million.
In the second quarter of 2019, we issued $500 million of 3.90% senior notes due May 1, 2029 and redeemed the $500 million outstanding aggregate principal balance of our 5.875% senior notes due August 15, 2020.
Liquidity
We believe that our present cash flows from operating, investing and financing activities are sufficient to fund our current and expected working capital and debt obligation needs and we do not expect this to change in the near term. There are currently no amounts outstanding under our $250 million senior unsecured revolving credit facility and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago (FHLBC).
CCC paid dividends of $975 million and $1,065 million to CNAF during 2020 and 2019.
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.
On February 5, 2021, in connection with the closing of the retroactive reinsurance transaction with Cavello, we transferred approximately $630 million of cash into a collateral trust account as security for Cavello’s obligations under the terms of the agreement. See Note S to the Consolidated Financial Statements included under Item 8 for further information on the retroactive reinsurance transaction with Cavello.

Common Stock Dividends
Dividends of $3.48 per share on our common stock, including a special dividend of $2.00 per share, were declared and paid in 2020. On February 5, 2021, our Board of Directors declared a quarterly dividend of $0.38 per share and a special dividend of $0.75 per share, payable March 11, 2021 to stockholders of record on February 22, 2021. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs and regulatory constraints.
Our ability to pay dividends and other credit obligations is significantly dependent on receipt of dividends from our subsidiaries. The payment of dividends to us by our insurance subsidiaries without prior approval of the insurance department of each subsidiary's domiciliary jurisdiction is limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective state insurance departments.
Further information on our dividends from subsidiaries is provided in Note M to the Consolidated Financial Statements included under Item 8.

Ratings
Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries are rated by major rating agencies and these ratings reflect the rating agency's opinion of the insurance company's financial strength, operating performance, strategic position and ability to meet its obligations to policyholders. Agency ratings are not a recommendation to buy, sell or hold any security and may be revised or withdrawn at any time by the issuing organization. Each agency's rating should be evaluated independently of any other agency's rating. One or more of these agencies could take action in the future to change the ratings of our insurance subsidiaries.
The table below reflects the Insurer Financial Strength Ratings of CNA's insurance company subsidiaries issued by A.M. Best, Moody's, S&P and Fitch. The table also includes the ratings for CNAF's senior debt.

ACCOUNTING STANDARDS UPDATE
For a discussion of Accounting Standards Updates adopted as of January 1, 2020 and that will be adopted in the future, see Note A to the Consolidated Financial Statements included under Item 8.
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:
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 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, drive significant decreases in our premium volume and result 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 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
51

Table of Contents
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;
regulatory limitations and restrictions, including limitations upon our ability to receive dividends from our insurance subsidiaries, imposed by regulatory authorities, including regulatory capital adequacy standards; and
the increasing complexities and regulatory costs relating to operations in Europe resulting from the completion of Brexit and the formation of a new European underwriting subsidiary as a result thereof.
Impact of Natural and Man-Made Disasters and Mass Tort Claims
weather and other natural physical events, including the severity and frequency of storms, hail, snowfall and other winter conditions, natural disasters such as hurricanes and earthquakes, as well as climate change, including effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, wildfires, rain, hail and snow;
regulatory requirements imposed by coastal state regulators in the wake of hurricanes or other natural disasters, including limitations on the ability to exit markets or to non-renew, cancel or change terms and conditions in policies, as well as mandatory assessments to fund any shortfalls arising from the inability of quasi-governmental insurers to pay claims;
man-made disasters, including the possible occurrence of terrorist attacks, the unpredictability of the nature, targets, severity or frequency of such events, and the effect of the absence or insufficiency of applicable terrorism legislation on coverages;
the occurrence of epidemics and pandemics; and
mass tort claims, including those related to exposure to potentially harmful products or substances such as glyphosate, lead paint and opioids; and claims arising from changes that repeal or weaken tort reforms, such as those related to abuse reviver statutes.
Our forward-looking statements speak only as of the date of the filing of this Annual Report on Form 10-K 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 filing of this Annual Report on Form 10-K, even if our expectations or any related events or circumstances change.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our financial instruments are exposed to various market risks, such as interest rate risk, equity price risk and foreign currency risk. Due to the level of risk associated with certain invested assets and the level of uncertainty related to changes in the value of these assets, it is possible that changes in these risks in the near term could have a material adverse impact on our results of operations, financial condition or equity.
Discussions herein regarding market risk focus on only one element of market risk, which is price risk. Price risk relates to changes in the level of prices due to changes in interest rates, equity prices, foreign exchange rates or other factors such as credit spreads. The fair value of our financial instruments is generally adversely affected when interest rates rise, equity markets decline or the dollar strengthens against foreign currency.
Active management of market risk is integral to our operations. We may take the following actions to manage our exposure to market risk within defined tolerance ranges: (1) change the character of future investments purchased or sold or (2) use derivatives to offset the market behavior of existing assets and liabilities or assets expected to be purchased and liabilities expected to be incurred.
Sensitivity Analysis
We monitor our sensitivity to interest rate changes by revaluing financial assets and liabilities using a variety of different interest rates. The Company uses duration and convexity at the security level to estimate the change in fair value that would result from a change in each security's yield. Duration measures the price sensitivity of an asset to changes in yield. Convexity measures how the duration of the asset changes with interest rates. The duration and convexity analysis takes into account the unique characteristics (e.g., call and put options and prepayment expectations) of each security in determining the hypothetical change in fair value. The analysis is performed at the security level and aggregated up to the asset category levels for reporting in the tables below.
The evaluation is performed by applying an instantaneous change in yield rates of varying magnitudes on a static balance sheet to determine the effect such a change in rates would have on our fair value at risk and the resulting effect on stockholders' equity. The analysis presents the sensitivity of the fair value of our financial instruments to selected changes in capital market rates and index levels. The range of change chosen reflects our view of changes that are reasonably possible over a one-year period. The selection of the range of values chosen to represent changes in interest rates should not be construed as our prediction of future market events, but rather an illustration of the impact of such events.
The sensitivity analysis estimates the decline in the fair value of our interest sensitive assets and liabilities that were held as of December 31, 2020 and 2019 due to an instantaneous change in the yield of the security at the end of the period of 100 and 150 basis points, with all other variables held constant.
The sensitivity analysis also assumes an instantaneous 10% and 20% decline in the foreign currency exchange rates versus the United States dollar from their levels as of December 31, 2020 and 2019, with all other variables held constant.
Equity price risk was measured assuming an instantaneous 10% and 25% decline in the S&P 500 from its level as of December 31, 2020 and 2019, with all other variables held constant. Our common stock holdings, which are included in equity securities, were assumed to be highly and positively correlated with the S&P 500 index. The value of limited partnerships are also affected by changes in equity markets, so a model was developed to analyze the observed changes in the value of limited partnerships held by the Company over a multiple year period along with the corresponding changes in the S&P 500 index. The result of the model allowed us to estimate the change in value of limited partnerships due to equity risk.

CNA Financial Corporation
Notes to Consolidated Financial Statements
Note A.  i Summary of Significant Accounting Policies
Basis of Presentation
 i The Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately  i 89.6% of the outstanding common stock of CNAF as of December 31, 2020. / 
The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated.  i The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
Recently Adopted Accounting Standards Updates (ASU)
 i 
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 $ i 5 million decrease in Retained earnings, with a corresponding $ i 7 million allowance for credit losses recorded for Mortgage loans partially offset by a $ i 2 million tax impact.
The allowance for uncollectible reinsurance and insurance receivables was unchanged as a result of adopting the new guidance. At adoption, an allowance for credit losses of $ i 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.
See the accounting policy discussion within this Note, as well as Notes B and G to the Consolidated Financial Statements for additional information regarding credit losses.
ASU 2014-09: In May 2014, the FASB issued ASU No. 2014-09, Revenue Recognition (Topic 606): Revenue from Contracts with Customers. The standard excludes from its scope the accounting for insurance contracts, financial instruments, and certain other agreements that are governed under other GAAP guidance, but the standard does apply to certain of the Company's warranty products and services. The updated guidance requires an entity to recognize revenue as performance obligations are met, in an amount that reflects the consideration the entity is entitled to receive for the transfer of the promised goods or services.

Table of Contents
On January 1, 2018, the Company adopted the updated guidance using the modified retrospective method applied to all contracts which were not completed as of the date of adoption and recognized a cumulative effect adjustment that decreased Retained earnings by $ i 66 million, net of tax.
See Note R to the Consolidated Financial Statements for additional information regarding non-insurance revenues from contracts with customers.
ASU 2016-01: In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.  The updated accounting guidance requires changes to the reporting model for financial instruments. The guidance primarily changes the model for equity securities by requiring changes in the fair value of equity securities (except those accounted for under the equity method of accounting, those without readily determinable fair values and those that result in consolidation of the investee) to be recognized through the income statement.
The Company adopted the updated guidance on January 1, 2018 and recognized a cumulative effect adjustment that increased beginning Retained earnings by $ i 28 million, net of tax.
Accounting Standards Pending Adoption
In August 2018, the FASB issued ASU 2018-12, Financial Services-Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The updated accounting guidance requires changes to the measurement and disclosure of long-duration contracts. The guidance requires entities to annually update cash flow assumptions, including morbidity and persistency, and update discount rate assumptions quarterly using an upper-medium grade fixed-income instrument yield. The effect of changes in cash flow assumptions will be recorded in the Company's results of operations and the effect of changes in discount rate assumptions will be recorded in Other comprehensive income. This guidance is effective for interim and annual periods beginning after December 15, 2022. Early adoption is permitted. The Company may elect to apply the guidance 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 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.
Insurance Operations
Premiums:  i Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured and are principally earned ratably over the term of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.
Property and casualty contracts that are retrospectively rated or subject to audit premiums contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions. These provisions stipulate the adjustment due to loss experience of the insured during the coverage period, or changes in the level of exposure to insurance risk. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the coverage period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company either adjusts such estimated ultimate premium amounts during the course of the coverage period based on actual results to date, or by conducting premium audits after the policy has expired to determine the final exposure to insured risks. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.
Insurance receivables include balances due currently or in the future, including amounts due from insureds related to paid losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. A loss rate methodology is used to determine expected credit losses for insurance receivables. This methodology uses the Company’s historical annual credit losses relative to gross premium written to develop a range of credit loss rates for each dollar of gross written premium underwritten. The
62

Table of Contents
expected credit loss for amounts due from insureds under high deductible and retrospectively rated policies is calculated on a pool basis, informed by historical default rate data obtained from major rating agencies. Changes in the allowance are presented as a component of Other operating expenses on the Consolidated Statements of Operations. Amounts are considered past due based on policy payment terms. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached. See the Credit Losses section of this note for additional information on the Company’s allowances for expected credit losses.
Claim and claim adjustment expense reserves:  i Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (A&EP), workers' compensation lifetime claims and long term care claims, are not discounted and are based on i) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; ii) estimates of incurred but not reported (IBNR) losses; iii) estimates of losses on assumed reinsurance; iv) estimates of future expenses to be incurred in the settlement of claims; v) estimates of salvage and subrogation recoveries and vi) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets.
Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $ i  i 1.2 /  billion as of December 31, 2020 and 2019. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on the Consolidated Balance Sheets.
Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. The Company's obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and are discounted at a weighted average interest rate of  i 6.5% and  i 7.1% as of December 31, 2020 and 2019. As of December 31, 2020 and 2019, the discounted reserves for unfunded structured settlements were $ i 520 million and $ i 497 million, net of discount of $ i 657 million and $ i 724 million. For the years ended December 31, 2020, 2019 and 2018, the amount of interest recognized on the discounted reserves of unfunded structured settlements was $ i 35 million, $ i 36 million and $ i 40 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders’ benefits on the Consolidated Statements of Operations, but is excluded from the Company’s disclosure of prior year loss reserve development.
Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. At December 31, 2020 and 2019, workers' compensation lifetime claim reserves are discounted at a  i  i 3.5 / % interest rate. As of December 31, 2020 and 2019, the discounted reserves for workers’ compensation lifetime claim reserves were $ i 258 million and $ i 293 million, net of discount of $ i 113 million and $ i 135 million. For the years ended December 31, 2020, 2019 and 2018, the amount of interest accretion recognized on the discounted reserves of workers’ compensation lifetime claim reserves was $ i 15 million, $ i 21 million and $ i 16 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations, but is excluded from the Company's disclosure of prior year loss reserve development.
Long term care claim reserves for policyholders that are currently receiving benefits are calculated using mortality and morbidity assumptions based on Company and industry experience. These long term care claim reserves are discounted at a weighted average interest rate of  i 5.8% and  i 5.9% as of December 31, 2020 and 2019. As of December 31, 2020 and 2019, such discounted reserves totaled $ i 2.7 billion and $ i 2.7 billion, net of discount of $ i 439 million and $ i 462 million.

Table of Contents
Future policy benefit reserves:  i Future policy benefit reserves represent the active life reserves related to the Company's long term care policies for policyholders that are not currently receiving benefits and are computed using the net level premium method, which incorporates actuarial assumptions as to morbidity, persistency, inclusive of mortality, discount rate, future premium rate adjustments and expenses. Expense assumptions primarily relate to claim adjudication. These assumptions are locked in over the life of the policy; however if a premium deficiency emerges, the assumptions are unlocked and the future policy benefit reserves are increased. The September 30, 2020 gross premium valuation (GPV) indicated a premium deficiency of $ i 74 million and future policy benefit reserves at that date 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. /  Long term care active life reserves are discounted at a weighted average interest rate of  i 5.4% and  i 5.7% as of December 31, 2020 and 2019.
In circumstances where the cash flow projections supporting future policy benefit reserves are expected to result in profits being recognized in early future years followed by losses in later future years, the future policy benefit reserves are increased in the future profitable years by an amount necessary to offset losses that are projected to be recognized in later future years.  The amount of the additional future policy benefit reserves recorded in each period is determined by applying the ratio of the present value of future losses divided by the present value of future profits from the most recently completed GPV to long term care core income in that period. 
Insurance-related assessments:  i Liabilities for insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2020 and 2019, the liability balances were $ i 82 million and $ i 84 million.
Reinsurance:  i Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.
Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefit reserves. Reinsurance receivables are reported net of an allowance for uncollectible amounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of the Company.
The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. For assessing expected credit losses, the Company separates reinsurance receivables into two pools: voluntary reinsurance receivables and involuntary receivables related 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. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if the Company becomes aware of significant changes related to a reinsurer. The allowance for uncollectible reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer financial strength rating and solvency, industry experience and current and forecast economic conditions. Because billed receivables generally approximate  i 5% or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for uncollectible reinsurance receivables are presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations. See the Credit Losses section of this note for additional information on the Company's allowances for expected credit losses.
64

Table of Contents
Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables from insolvent insurers related to paid losses are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.
A loss portfolio transfer is a retroactive reinsurance contract. If the cumulative claim and allocated claim adjustment expenses ceded under a loss portfolio transfer exceed the consideration paid, the resulting gain from such excess is deferred and amortized into earnings in future periods in proportion to actual recoveries under the loss portfolio transfer. In any period in which there is a revised estimate of claim and allocated claim adjustment expenses and the loss portfolio transfer is in a gain position, the deferred gain is recalculated as if the revised estimate was available at the inception date of the loss portfolio transfer and the change in the deferred gain is recognized in earnings.
Deferred acquisition costs:  i Deferrable acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned. Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs.
The Company evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current period results of operations.
Policyholder dividends:  i Policyholder dividends are paid to participating policyholders within the worker’s compensation and surety lines of business. Net written premiums for participating dividend policies were approximately  i  i  i 1 /  / % of total net written premiums for each of the years ended December 31, 2020, 2019 and 2018. Dividends to policyholders are accrued according to the Company's best estimate of the amount to be paid in accordance with contractual provisions and applicable state laws. Dividends to policyholders are presented as a component of Insurance claims & policyholders' benefits on the Consolidated Statements of Operations and Other liabilities on the Consolidated Balance Sheets. / 
Investments
 i 
The Company classifies its fixed maturity securities as either available-for-sale or trading, and as such, they are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Operations. Changes in fair value related to available-for-sale securities are reported as a component of Other comprehensive income.
The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts, which are included in Net investment income on the Consolidated Statements of Operations. The amortization of premium and accretion of discount for fixed maturity securities takes into consideration call and maturity dates that produce the lowest yield.
For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments predominantly using the retrospective method.
To the extent that unrealized gains on fixed maturity securities supporting long term care products and structured settlements not funded by annuities would result in a premium deficiency if those gains were realized, a related increase in Insurance reserves is recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (Shadow Adjustments). Shadow Adjustments, net of tax, increased $ i 575 million and $ i 1,120 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020 and 2019, net unrealized gains on investments included in Accumulated other comprehensive income
 /

Table of Contents
(AOCI) were correspondingly reduced by Shadow Adjustments of $ i 2,773 million and $ i 2,198 million, respectively.
Equity securities are carried at fair value. The Company's non-redeemable preferred stock contain characteristics of debt securities, are priced similarly to bonds and are held primarily for income generation through periodic dividends. While recognition of gains and losses on these securities is not discretionary, management does not consider the changes in fair value of non-redeemable preferred stock to be reflective of our primary operations. As such, the changes in the fair value of these securities are recorded through Net investment gains (losses) on the Consolidated Statements of Operations. The Company owns certain common stock with the intention of holding the securities primarily for market appreciation and as such, the changes in the fair value of these securities are recorded through Net investment income.
The Company's carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the general partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. Changes in net asset values are accounted for under the equity method and recorded within Net investment income on the Consolidated Statements of Operations.
Mortgage loans are commercial in nature, are carried at unpaid principal balance, net of unamortized fees and an allowance for expected credit losses, and are recorded once funded. 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. The Company applies expected credit loss rates by pool to the outstanding receivable balances. Changes in the allowance for mortgage loans are presented as a component of Net investment gains (losses) on the Consolidated Statements of Operations. Prior to 2020, mortgage loans were evaluated on an individual loan basis considering the collection experience of each loan and other credit quality indicators such as DSCR and the credit-worthiness of the borrower or tenants of credit tenant loan properties. Mortgage loans were considered to be impaired loans and a loss incurred when it was probable that contractual principal and interest payments would not be collected and any impairment losses were recognized as a direct write-down of amortized cost. See the Credit Losses section of this note for additional information on the Company’s allowances for expected credit losses. Interest income from mortgage loans is recognized on an accrual basis using the effective yield method.
Other invested assets include overseas deposits. Overseas deposits are valued using the net asset value per share (or equivalent) practical expedient. They are primarily short-term government securities, agency securities and corporate bonds held in trusts that are managed by Lloyd's of London. These funds are required of Lloyd's syndicates to protect policyholders in overseas markets and may be denominated in local currency.
Short term investments are carried at fair value, with the exception of cash accounts earning interest, which are carried at cost and approximate fair value. Changes in fair value are reported as a component of Other comprehensive income.
Purchases and sales of all securities are recorded on the trade date, except for private placement securities, including bank loan participations, which are recorded once funded. Net investment gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.
 i In the normal course of investing activities, the Company enters into relationships with variable interest entities (VIEs), as both an investor in limited partnerships and asset-backed securities issued by third-party VIEs. The Company is not the primary beneficiary of these VIEs, and therefore does not consolidate them. The Company determines whether it is the primary beneficiary of a VIE based on a qualitative assessment of the relative power and benefits of the Company and the other participants in the VIE. The Company’s maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the Company’s Consolidated Balance Sheets and any unfunded commitments.
66

Table of Contents
An available for sale security is impaired if the fair value of the security is less than its cost adjusted for accretion, amortization and allowance for credit losses. When a security is impaired, it is evaluated to determine whether the Company intends to sell the security before recovery of amortized cost or whether a credit loss exists. Losses on securities that the Company intends to sell are recognized as impairment losses within Net investment gains (losses) on the Consolidated Statements of Operations. If a credit loss exists, an allowance is established and the corresponding amount is recognized as an impairment loss within Net investment gains (losses) on the Consolidated Statements of Operations. The allowance for credit losses related to available-for-sale fixed maturity securities is the difference between the 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. In subsequent periods, the allowance is reviewed, with any changes in the allowance presented as a component of Net investment gains (losses) on the Consolidated Statements of Operations. Changes in the difference between the amortized cost basis, net of the allowance, and the fair value, are recognized in Other comprehensive income.
 i 
Significant judgment is required in the determination of whether an impairment loss has occurred for a security. The Company follows a consistent and systematic process for determining and recording an impairment loss, including the evaluation of securities in an unrealized loss position and securities with an allowance for credit losses on at least a quarterly basis.
The Company’s assessment of whether an impairment loss has occurred incorporates both quantitative and qualitative information. A credit loss exists if the present value of cash flows expected to be collected is less than the amortized cost basis. Significant assumptions enter into these cash flow projections including delinquency rates, probable risk of default, loss severity upon a default, over collateralization and interest coverage triggers and credit support from lower level tranches. The Company 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 and long-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. See the Credit Losses section of this note for additional information on the Company’s allowances for expected credit losses.
Prior to 2020, the Company’s assessment of whether an impairment loss occurred also incorporated both quantitative and qualitative information. Fixed maturity securities in an unrealized loss position that the Company intended to sell, or it more likely than not would be required to sell before recovery of amortized cost, were considered to be impaired and the entire difference between the amortized cost basis and fair value of the security was recognized as an impairment loss in earnings as a direct write-down of amortized cost. The remaining fixed maturity securities in an unrealized loss position were evaluated to determine if a credit loss existed. If a credit loss was determined to exist, the credit loss was recognized in earnings as a direct write-down of amortized cost.
Credit Losses
 i The allowances for credit losses on fixed maturity securities, mortgage loans, reinsurance receivables and insurance receivables are valuation accounts that are reported as a reduction of a financial asset’s cost basis and are 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
67

Table of Contents
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. Amounts are written off against the allowance when determined to be uncollectible.
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 Consolidated Balance Sheet.
Prior to 2020, the allowance for uncollectible reinsurance and insurance receivables was measured using an incurred loss methodology.
Deferred Non-Insurance Warranty Revenue and Acquisition Expense
 i 
Non-insurance warranty revenue is primarily generated from separately-priced service contracts that provide mechanical breakdown and other coverages to vehicle or consumer goods owners. The warranty contracts generally provide coverage from  i 1 month to  i 10 years. For warranty products where the Company acts as the principal in the transaction, Non-insurance warranty revenue is reported on a gross basis, with amounts paid by customers reported as Non-insurance warranty revenue and commissions paid to agents reported as Non-insurance warranty expense.
Non-insurance warranty revenue is reported net of any premiums related to contractual liability coverage issued by the Company's insurance operations. Additionally, the Company provides warranty administration services for dealer and manufacturer obligor warranty products, which include limited warranties and guaranteed automobile protection waivers. The Company recognizes Non-insurance warranty revenue over the service period in proportion to the actuarially determined expected claims emergence pattern. Customers pay in full at the inception of the warranty contract. The liability for deferred revenue represents the unearned portion of revenue in advance of the Company's performance. The deferred revenue balance includes amounts which are refundable on a pro rata basis upon cancellation.
Dealers, retailers and agents earn commission for assisting the Company in obtaining non-insurance warranty contracts. Additionally, the Company utilizes a third-party to perform warranty administrator services for its consumer goods warranties. These costs, which are deferred and recorded as Deferred non-insurance warranty acquisition expense, are amortized to Non-insurance warranty expense consistent with how the related revenue is recognized. The Company evaluates deferred costs for recoverability including consideration of anticipated investment income. Adjustments to deferred costs, if necessary, are recorded in the current period results of operations.
 / 
Income Taxes
 i The Company and its eligible subsidiaries (CNA Tax Group) are included in the consolidated federal income tax return of Loews and its eligible subsidiaries. The Company accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes will not be realized. The Company releases tax effects from AOCI utilizing the security-by-security approach for Net unrealized gains (losses) on investments with an allowance for credit losses and Net unrealized gains (losses) on other investments. For

Pension and postretirement benefits, tax effects from AOCI are released at enacted tax rates based on the pre-tax adjustments to pension liabilities or assets recognized within Other comprehensive income.
Pension and Postretirement Benefits
 i 
The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities on the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits, and actuarial gains and losses arising from differences between actual experience and actuarial assumptions, are recognized in the year in which the changes occur through Other comprehensive income. Unrecognized actuarial gains and losses in excess of 10% of the greater of the beginning of the year projected benefit obligation or fair value of plan assets (the corridor) are amortized as a component of net periodic pension cost (benefit) over the average remaining life expectancy of the plan participants. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits and amortization of actuarial gains and losses are recognized on the Consolidated Statements of Operations.
The vested benefit obligation for the CNA Retirement Plan is determined based on eligible compensation and accrued service for previously entitled employees. Effective June 30, 2015, future benefit accruals under the CNA Retirement Plan were eliminated and the benefit obligations were frozen.
Stock-Based Compensation
 i The Company records compensation expense using the fair value method for all awards it grants, modifies or cancels primarily on a straight-line basis over the requisite service period, generally  i three years. / 
Foreign Currency
 i The Company's foreign subsidiaries' balance sheet accounts are translated at the exchange rates in effect at each reporting date and income statement accounts are either translated at the exchange rates on the date of the transaction or at average exchange rates. Foreign currency translation gains and losses are reflected in Stockholders' equity as a component of AOCI. Foreign currency transaction gains of $ i 13 million, $ i 1 million and $ i 1 million were included in determining Net income for the years ended December 31, 2020, 2019 and 2018, respectively.
Leases
 i 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 right-of-use (ROU) assets and lease liabilities are included in Other assets and Other liabilities on the Company's 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 if an arrangement is a lease at inception. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value 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 options that the Company expects to exercise. The discount rate used to determine the commencement date present value of lease payments is typically the Company’s secured borrowing rate, as most of the Company’s leases do not provide an implicit rate. ROU assets include any lease payments required to be made prior to commencement and exclude lease incentives. The Company has elected to account for its lease and non-lease components as a single lease component. The Company’s non-lease components consist of variable lease costs not based on an index or rate and are excluded from the measurement of ROU assets and lease liabilities. Variable lease costs not based on an index or rate are treated as period costs, and represent charges for services provided by the landlord and the Company's reimbursement to the landlord for costs such as real estate taxes and insurance.
The Company occupies office facilities under lease agreements that expire at various dates. The Company's lease agreements do not contain significant residual value guarantees, restrictions or covenants. The Company does not have any significant finance leases.

Property and Equipment
 i Property and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is determined principally on the straight-line method. Furniture and fixtures are depreciated over  i seven years. Office equipment is depreciated over  i five years. The estimated lives for data processing equipment and software generally range from three to  i five years, but can be as long as  i ten years. Leasehold improvements are depreciated over the corresponding lease terms not to exceed the underlying asset life. / 
Goodwill
 i 
Goodwill represents the excess of purchase price over the fair value of the net assets of acquired entities and businesses. Goodwill in the International segment may change from period to period as a result of foreign currency translation.
Goodwill is tested for impairment annually or when certain triggering events require such tests. As a result of reviews completed for the year ended December 31, 2020, the Company determined that the estimated fair value of the reporting units were in excess of their carrying value including Goodwill. Changes in future periods in assumptions about the level of economic capital, business growth, earnings projections or the weighted average cost of capital could result in goodwill impairment.
Other Intangible Assets
 i Other intangible assets are reported within Other assets on the Consolidated Balance Sheets. Finite-lived intangible assets are amortized over their estimated useful lives. Indefinite-lived other intangible assets are tested for impairment annually or when certain triggering events require such tests.
Earnings (Loss) Per Share Data
 i 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 years ended December 31, 2020, 2019 and 2018, approximately  i 772 thousand,  i 961 thousand and  i 943 thousand potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods,  i 8 thousand,  i 1 thousand and  i 6 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.
Supplementary Cash Flow Information
Cash payments made for interest were $ i 124 million, $ i 136 million and $ i 145 million for the years ended December 31, 2020, 2019 and 2018. Cash payments made for income taxes were $ i 108 million, $ i 255 million and $ i 308 million for the years ended December 31, 2020, 2019 and 2018.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the December 31, 2020 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 December 31, 2020.

Actual maturities may differ from contractual maturities because certain securities may be called or prepaid. Securities not due at a single date are allocated based on weighted average life.
Limited Partnerships
The carrying value of limited partnerships as of December 31, 2020 and 2019 was $ i 1,619 million and $ i 1,752 million, which includes net undistributed earnings of $ i 235 million and $ i 229 million. Limited partnerships comprising  i 49% of the total carrying value are reported on a current basis through December 31, 2020 with no reporting lag,  i 10% are reported on a one month lag and the remainder are reported on more than a one month lag. The number of limited partnerships held and the strategies employed provide diversification to the limited partnership portfolio and the overall invested asset portfolio.
Limited partnerships comprising  i 51% and  i 61% of the carrying value as of December 31, 2020 and 2019 employ hedge fund strategies. Limited partnerships comprising  i 40% and  i 33% of the carrying value as of December 31, 2020 and 2019 were invested in private debt and equity, and the remainder was primarily invested in real estate strategies. Hedge fund strategies include both long and short positions in fixed income, equity and derivative instruments. These hedge fund strategies may seek to generate gains from mispriced or undervalued securities, price differentials between securities, distressed investments, sector rotation or various arbitrage disciplines. Within hedge fund strategies, approximately  i 55% were equity related,  i 26% pursued a multi-strategy approach,  i 14% were focused on distressed investments and  i 5% were fixed income related as of December 31, 2020.
The ten largest limited partnership positions held totaled $ i 775 million and $ i 893 million as of December 31, 2020 and 2019. Based on the most recent information available regarding the Company’s percentage ownership of the individual limited partnerships, the carrying value reflected on the Consolidated Balance Sheets represents approximately  i  i 2 / % of the aggregate partnership equity as of December 31, 2020 and 2019, and the related income reflected on the Consolidated Statements of Operations represents approximately  i 2%,  i 2% and  i 3% of the changes in aggregate partnership equity for the years ended December 31, 2020, 2019 and 2018.
There are risks inherent in limited partnership investments which may result in losses due to short-selling, derivatives or other speculative investment practices. The use of leverage increases volatility generated by the underlying investment strategies.
The Company’s hedge fund limited partnership investments contain withdrawal provisions that generally limit liquidity for a period of thirty days up to one year or longer. Private equity and other non-hedge funds generally do not permit voluntary withdrawals. Typically, hedge fund withdrawals require advance written notice of up to 90 days.

Table of Contents
Derivative Financial Instruments
The Company may use derivatives in the normal course of business, primarily in an attempt to reduce its exposure to market risk (principally interest rate risk and foreign currency risk) stemming from various assets and liabilities. The Company's principal objective under such strategies is to achieve the desired reduction in economic risk, even if the position does not receive hedge accounting treatment.
The Company may enter into interest rate swaps, futures and forward commitments to purchase securities to manage interest rate risk. The Company may use foreign currency forward contracts to manage foreign currency risk.
Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to the instruments recognized on the Consolidated Balance Sheets. The Company generally requires that all over-the-counter derivative contracts be governed by an International Swaps and Derivatives Association Master Agreement, and exchanges collateral under the terms of these agreements with its derivative investment counterparties depending on the amount of the exposure and the credit rating of the counterparty. Gross estimated fair values of derivative positions are presented in Other invested assets and Other liabilities on the Consolidated Balance Sheets. The Company does not offset derivative positions against the fair value of collateral provided or positions subject to netting arrangements. There would be no significant difference in the balance included in such accounts if the estimated fair values were presented net as of December 31, 2020 and 2019.
There was  i  i no /  cash collateral provided by the Company or cash collateral received from counterparties as of December 31, 2020 or 2019.
The Company holds an embedded derivative on a funds withheld liability with a notional value of $ i 190 million and $ i 182 million and a fair value of $( i 19) million and $( i 7) million as of December 31, 2020 and 2019. The embedded derivative on the funds withheld liability is accounted for separately and reported with the funds withheld liability in Other liabilities on the Consolidated Balance Sheets.
Investment Commitments
As part of its overall investment strategy, the Company invests in various assets which require future purchase, sale or funding commitments. These investments are recorded once funded, and the related commitments may include future capital calls from various third-party limited partnerships, signed and accepted mortgage loan applications, and obligations related to private placement securities. As of December 31, 2020, the Company had commitments to purchase or fund approximately $ i 1,210 million and sell approximately $ i 85 million under the terms of these investments.
Investments on Deposit
Securities with carrying values of approximately $ i 3.0 billion and $ i 2.7 billion were deposited by the Company’s insurance subsidiaries under requirements of regulatory authorities and others as of December 31, 2020 and 2019.
Cash and securities with carrying values of approximately $ i 1.1 billion and $ i 1.1 billion were deposited with financial institutions in trust accounts or as collateral for letters of credit to secure obligations with various third parties as of December 31, 2020 and 2019.

Note C.  i 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 Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.
As of December 31, 2020 and December 31, 2019, there were $ i 71 million and $ i 60 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.

Note D.  i Income Taxes
The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. Loews and the Company have agreed that for each taxable year, the Company will 1) be paid by Loews the amount, if any, by which the Loews consolidated federal income tax liability is reduced by virtue of the inclusion of the CNA Tax Group in the Loews consolidated federal income tax return, or 2) pay to Loews an amount, if any, equal to the federal income tax that would have been payable by the CNA Tax Group filing a separate consolidated tax return. In the event that Loews should have a net operating loss in the future computed on the basis of filing a separate consolidated tax return without the CNA Tax Group, the Company may be required to repay tax recoveries previously received from Loews. This agreement may be canceled by either party upon 30 days written notice.
For the years ended December 31, 2020, 2019 and 2018, the Company paid $ i 65 million, $ i 239 million and $ i 275 million to Loews related to federal income taxes.
For 2018 through 2020, Loews and the Company participate in the Internal Revenue Service (IRS) Compliance Assurance Process (CAP), which is a voluntary program for large corporations. Under CAP, the IRS generally conducts a real-time audit and works contemporaneously with the Company to resolve any issues prior to the filing of the 2018 and 2019 tax returns. The 2018 and 2019 examinations were completed in this manner. For 2020, the Company was selected to participate in the phase of CAP reserved for taxpayers whose risk of noncompliance does not warrant use of IRS resources. The Company believes that participation in CAP should reduce tax-related uncertainties, if any.
As of December 31, 2020 and 2019, there were  i  i no /  unrecognized tax benefits.
The Company recognizes interest accrued related to unrecognized tax benefits and tax refund claims in Income tax (expense) benefit on the Consolidated Statements of Operations. The Company recognizes penalties (if any) in Income tax (expense) benefit on the Consolidated Statements of Operations. During 2020, 2019 and 2018 the Company recognized  i  i  i no /  /  interest and  i  i  i no /  /  penalties.

Note E.  i Claim, Claim Adjustment Expense and Future Policy Benefit Reserves
Property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including IBNR claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to 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.

Reserving Methodology
In developing claim and claim adjustment expense (loss or losses) reserve estimates, the Company's actuaries perform detailed reserve analyses that are staggered throughout the year. Every reserve group is reviewed at least once during the year, but most are reviewed more frequently. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. Factors considered include, but are not limited to, the historical pattern and volatility of the actuarial indications, the sensitivity of the actuarial indications to changes in paid and incurred loss patterns, the consistency of claims handling processes, the consistency of case reserving practices, changes in the Company's pricing and underwriting, pricing and underwriting trends in the insurance market and legal, judicial, social and economic trends. In addition to the detailed analyses, the Company reviews actual loss emergence for all products each quarter.
In developing the loss reserve estimates for property and casualty contracts, the Company generally projects ultimate losses using several common actuarial methods as listed below. The Company reviews the various indications from the various methods and applies judgment to select an actuarial point estimate. The carried reserve may differ from the actuarial point estimate as a result of the Company's consideration of the factors noted above as well as the potential volatility of the projections associated with the specific product being analyzed and other factors affecting claims costs that may not be quantifiable through traditional actuarial analysis. The indicated required reserve is the difference between the selected ultimate loss and the inception-to-date paid losses. The difference between the selected ultimate loss and the case incurred or reported loss is IBNR. IBNR includes a provision for development on known cases as well as a provision for late reported incurred claims.
The most frequently utilized methods to project ultimate losses include the following:
Paid development: The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident years with further expected changes in paid loss.
Incurred development: The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses.
Loss ratio: The loss ratio method multiplies premiums by an expected loss ratio to produce ultimate loss estimates for each accident year.
Bornhuetter-Ferguson using premiums and paid loss: The Bornhuetter-Ferguson using premiums and paid loss method is a combination of the paid development approach and the loss ratio approach. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method.
Bornhuetter-Ferguson using premiums and incurred loss: The Bornhuetter-Ferguson using premiums and incurred loss method is similar to the Bornhuetter-Ferguson using premiums and paid loss method except that it uses case incurred losses.
Frequency times severity: The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident year to produce ultimate loss estimates.
Stochastic modeling: The stochastic modeling produces a range of possible outcomes based on varying assumptions related to the particular product being modeled.
For many exposures, especially those that are considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, the Company's actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method. For most of the Company's products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, the Company may not assign any weight to the paid and incurred development methods. The Company will use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods. For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because the Company's history includes a sufficient number of
87

Table of Contents
years to cover the entire period over which paid and incurred losses are expected to change. However, the Company may also use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods for short-tail exposures. For other more complex reserve groups where the above methods may not produce reliable indications, the Company uses additional methods tailored to the characteristics of the specific situation.
The Company's reserving methodologies for mass tort and A&EP are similar as both are based on detailed reviews of large accounts with estimates of ultimate payments based on the facts in each case and the Company's view of applicable law and coverage litigation.

Segment Development Tables
For the Specialty, Commercial and International segments, the following tables present further detail and commentary on the development reflected in the financial statements for each of the periods presented. Also presented are loss reserve development tables that illustrate the change over time of reserves established for claim and allocated claim adjustment expenses arising from short-duration insurance contracts for certain lines of business within each of these segments. Not all lines of business or segments are presented based on their context to the Company's overall loss reserves, calendar year reserve development, or calendar year net earned premiums. Insurance contracts are considered to be short-duration contracts when the contracts are not expected to remain in force for an extended period of time.
The Cumulative Net Incurred Claim and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative net incurred claim and allocated claim adjustment expenses relating to each accident year at the end of the stated calendar year. Changes in the cumulative amount across time are the result of the Company's expanded awareness of additional facts and circumstances that pertain to the unsettled claims. The Cumulative Net Paid Claims and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative amount paid for claims in each accident year as of the end of the stated calendar year. The Net Strengthening or (Releases) of Prior Accident Year Reserves tables, reading across, show the net increase or decrease in the cumulative net incurred accident year claim and allocated claim adjustment expenses during each stated calendar year and indicates whether the reserves for that accident year were strengthened or released.
The information in the tables is reported on a net basis after reinsurance and does not include the effects of discounting. The information contained in calendar years 2019 and prior is unaudited. Information contained in the tables pertaining to the Company's International segment has been presented at the year-end 2020 foreign currency exchange rates for all periods presented to remove the effects of foreign currency exchange rate changes between calendar years. The Company has presented development information for the Hardy business prospectively from the date of acquisition and is presented as a separate table within the Company's International segment. To the extent the Company enters into a commutation, the transaction is reported on a prospective basis. To the extent that the Company enters into a disposition, the effects of the disposition are reported on a retrospective basis by removing the balances associated with the disposed of business.
The amounts reported for the cumulative number of reported claims include direct and assumed open and closed claims by accident year at the claimant level. The number excludes claim counts for claims within a policy deductible where the insured is responsible for payment of losses in the deductible layer. Claim count data for certain assumed reinsurance contracts is unavailable.
IBNR includes reserves for incurred but not reported losses and expected development on case reserves. The Company does not establish case reserves for allocated loss adjusted expenses (ALAE), therefore ALAE reserves are also included in the estimate of IBNR.

2020
Unfavorable development in medical professional liability was primarily due to higher than expected frequency of large losses in recent accident years and unfavorable outcomes on specific claims in older accident years.
Favorable development in other professional liability and management liability was primarily due to lower than expected loss emergence in accident year 2017 and accident years prior to 2010.
Favorable development in surety was due to lower than expected frequency and lack of systemic loss activity for accident years 2019 and prior.
2019
Unfavorable development in medical professional liability was primarily due to higher than expected severity in accident years 2016 through 2018 in the Company's aging services business, higher than expected severity in accident year 2013 in the Company's allied healthcare business, unfavorable outcomes on individual claims and higher than expected severity in accident year 2017 in the Company's dentists business.
Favorable development in other professional liability and management liability was primarily due to lower than expected claim frequency and favorable outcomes on individual claims in accident years 2017 and prior related to financial institutions, lower than expected large claim losses in recent accident years in the Company's public company directors and officers liability (D&O) business and lower than expected loss adjustment expenses across accident years 2010 through 2018.
Favorable development in surety was due to lower than expected frequency for accident years 2018 and prior.
Favorable development in warranty was due to lower than expected paid loss emergence on vehicle products.
2018
Unfavorable development in medical professional liability was primarily due to higher than expected severity in accident years 2014 and 2017 in the Company's hospitals business. Additionally, there was higher than expected frequency and severity in aging services in accident years 2014 through 2017 combined, partially offset by lower than expected frequency in accident year 2015.
Favorable development in other professional liability and management liability was primarily due to lower than expected claim frequency in recent accident years related to financial institutions and professional liability errors and omissions (E&O), favorable severity in accident years 2015 and prior related to professional liability E&O and favorable outcomes on individual claims in financial institutions in accident years 2013 and prior.
Favorable development in surety was due to lower than expected loss emergence for accident years 2017 and prior.

2020
Unfavorable development in commercial auto was due to higher than expected claim severity in the Company's middle market and construction business in recent accident years.
Unfavorable development in general liability was driven by higher than expected emergence in mass tort exposures, primarily due to New York reviver statute-related claims from accident years prior to 2010, increased bodily injury severities in accident years 2012 through 2016 and higher than expected frequency and severity in the Company’s umbrella business in accident years 2015 through 2019.
Favorable development in workers’ compensation was due to favorable medical trends driving lower than expected severity in multiple accident years.
Unfavorable development in property and other was primarily due to higher than expected large loss activity in accident year 2019 in the Company's middle market, national accounts and marine business units.
2019
Favorable development in commercial auto was primarily due to continued lower than expected severity across accident years 2015 and prior and a decline in bodily injury frequency in accident year 2018.

Favorable development in workers’ compensation was due to favorable medical trends driving lower than expected severity in accident years 2012 through 2018.
Favorable development in property and other was primarily driven by lower than expected claim severity related to catastrophe events in accident years 2017 and 2018.
2018
Unfavorable development in general liability was driven by higher than expected claim severity in unsupported umbrella in accident years 2013 through 2016. 
Favorable development in workers’ compensation was driven by lower frequency and severity experience and favorable impacts from California reforms.

(1) Effective January 1, 2020 the Property and Energy and Marine lines of business have been combined in the International segment. Prior period information has been conformed to the new line of business presentation.
2020
Favorable development in casualty was primarily driven by better than expected loss experience across Europe and Canada in multiple accident years.
Unfavorable development in property, energy and marine was driven by adverse experience on discontinued lines.
2019
Favorable development in casualty was driven by lower than expected large losses and claim severity in accident years 2018 and prior in Hardy, Europe and Canada.
Unfavorable development in property, energy and marine was driven by higher than expected claims in Hardy on 2018 accident year Asian catastrophe events.
Unfavorable development in specialty was primarily driven by professional indemnity within Europe financial lines in accident years 2017 and 2018 due to potential design and construct exposures.
2018
Favorable development in casualty was primarily driven by better than expected frequency in the liability portion of the package business in Canada and general liability in Europe.
Unfavorable development in specialty was driven by increased loss severity in the accident year 2017 in Europe professional indemnity. This was partially offset by favorable development in accident years 2015 and prior in Europe healthcare and technology.

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 LPT. At the effective date of the transaction, the Company ceded approximately $ i 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 $ i 4 billion. The $ i 1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $ i 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 $ i 2 billion and transferred to NICO billed third-party reinsurance receivables related to A&EP claims with a net book value of $ i 215 million, resulting in total consideration of $ i 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 $ i 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 Consolidated Statements of Operations.

Net unfavorable prior year development of $ i 125 million, $ i 150 million and $ i 178 million was recognized before consideration of cessions to the LPT for the years ended December 31, 2020, 2019 and 2018. The unfavorable development in 2020 and 2019 was driven by higher than anticipated defense and indemnity costs on known direct asbestos and environmental accounts and a reduction in estimated reinsurance recoverable. The unfavorable development in 2018 was driven by higher than anticipated defense and indemnity costs on known direct asbestos and environmental accounts and by paid losses on assumed reinsurance exposures. Additionally, in 2020, 2019 and 2018, the Company released $ i 25 million, $ i 25 million and $ i 16 million of its provision for uncollectible third-party reinsurance.
As of December 31, 2020 and 2019, the cumulative amounts ceded under the LPT were $ i 3.3 billion and $ i 3.2 billion. The unrecognized deferred retroactive reinsurance benefit was $ i 398 million and $ i 392 million as of December 31, 2020 and 2019 and is included within Other liabilities on the Consolidated Balance Sheets.

Life & Group Policyholder Reserves
The Company’s Life & Group segment includes its run-off long term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long term care policies provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and the Company has the ability to increase policy premiums, subject to state regulatory approval.
The Company maintains both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for the Life & Group segment. Claim and claim adjustment expense reserves consist of estimated reserves for long term care policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported. In developing the claim and claim adjustment expense reserve estimates for long term care policies, the Company’s actuaries perform a detailed claim reserve review on an annual basis. The review analyzes the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. In addition, claim and claim adjustment expense reserves are also maintained for the structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for structured settlement obligations, the Company's actuaries 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 reviews. Claim and claim adjustment expense reserves for long term care policies and structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements.
The Company completed its annual claim reserve reviews in the third quarter of 2020, 2019 and 2018. The Company's 2020 claim reserve reviews resulted in a $ i 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 $ i 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 and 2018 claim reserve reviews resulted in $ i 56 million and $ i 31 million pretax reductions 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 consist of the active life reserves related to the Company’s long term care policies for policyholders that are not currently receiving benefits and represent the present value of expected future benefit payments and expenses less expected future premium. The determination of these reserves requires management to make estimates and assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk.
The actuarial assumptions that management believes are subject to the most variability are morbidity, persistency, discount rates and anticipated future premium rate increases. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Discount rates are influenced by the investment yield on assets supporting long term care reserves which is subject to interest rate and market volatility and may also be affected by changes to the Internal Revenue Code. Future premium rate increases are generally subject to regulatory approval, and therefore the exact timing and size of the approved rate increases are unknown. As a result of this variability, the Company’s long term care reserves may be subject to material increases if actual experience develops adversely to the Company’s expectations.
Annually, in the third quarter, management assesses the adequacy of its long term care future policy benefit reserves by performing a 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.
108

Table of Contents
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.
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 $ i 74 million and a $ i 216 million pretax charge in policyholders' benefits reflected in the Company's results of operations. The Company’s 2018 GPV for the long term care future policy benefit reserves indicated the reserves were not deficient and no adjustment was required.

Note F.  i Legal Proceedings, Contingencies and Guarantees
The Company is a party to various claims and routine 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.
General Liability Premium Rate Adjustment Contingency
The Company recently became aware of discrepancies in the experience rating calculation of certain general liability policies. These calculation discrepancies resulted in certain policyholders being undercharged while others were overcharged. The Company has made corrections to its systems and processes to address the issue. The Company recorded a charge which reduced earned premium by $ i 14 million in anticipation of voluntarily issuing premium refunds in connection with policies written from January 1, 2018 through December 31, 2020 which were overcharged. The Company has contacted regulators in states with a significant anticipated volume of premium refunds. Fines or penalties related to the foregoing are reasonably possible, but the amount of such fines, if any, cannot be estimated at this time.
Guarantees
As of December 31, 2020 and 2019, the Company had recorded liabilities of approximately $ i  i 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 December 31, 2020, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $ i 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 G.  i Reinsurance
The Company cedes insurance to reinsurers to limit its maximum loss, provide greater diversification of risk, minimize exposures on larger risks and to exit certain lines of business. The ceding of insurance does not discharge the primary liability of the Company. A credit exposure exists with respect to reinsurance ceded to the extent that any reinsurer is unable to meet its obligations. A collectibility exposure also exists to the extent that the reinsurer disputes the liabilities assumed under reinsurance agreements. Property and casualty reinsurance coverages are tailored to the specific risk characteristics of each product line and the Company's retained amount varies by type of coverage. Reinsurance contracts are purchased to protect specific lines of business such as property and workers' compensation. Corporate catastrophe reinsurance is also purchased for property and workers' compensation exposure. The Company also utilizes facultative reinsurance in certain lines. In addition, the Company assumes reinsurance primarily through Hardy and as a member of various reinsurance pools and associations.

Refer to Note E to the Consolidated Financial Statements for information regarding the LPT. The Company has also excluded receivables from involuntary pools.
The Company attempts to mitigate its credit risk related to reinsurance by entering into reinsurance arrangements with reinsurers that have credit ratings above certain levels and by obtaining collateral. On a limited basis, the Company may enter into reinsurance agreements with reinsurers that are not rated, primarily captive reinsurers. Receivables from captive reinsurers are backed by collateral arrangements and comprise the majority of the voluntary reinsurance receivables within the B- to B++ rating distribution in the table above. The primary methods of obtaining collateral are through reinsurance trusts, letters of credit and funds withheld balances. Such collateral, limited by the balance of open recoverables, was approximately $ i 3.3 billion and $ i 3.2 billion as of December 31, 2020 and 2019.
The Company's largest recoverables from a single reinsurer as of December 31, 2020, including ceded unearned premium reserves, were approximately $ i 1.9 billion from subsidiaries of the Berkshire Hathaway Insurance Group, $ i 377 million from the Gateway Rivers Insurance Company and $ i 314 million from the Palo Verde Insurance Company. These amounts are substantially collateralized or otherwise secured. The recoverable from subsidiaries of the Berkshire Hathaway Insurance Group includes amounts related to third-party

Note I.  i Benefit Plans
Pension and Postretirement Health Care Benefit Plans
CNA sponsors noncontributory defined benefit pension plans, primarily through the CNA Retirement Plan, covering certain eligible employees. These plans are closed to new entrants. CNA's funding policy for defined benefit pension plans is to make contributions in accordance with applicable governmental regulatory requirements with consideration of the funded status of the plans.
Effective January 1, 2000, the CNA Retirement Plan was closed to new participants. Existing participants at that time were given a choice to either continue to accrue benefits under the CNA Retirement Plan or to cease accruals effective December 31, 1999. Employees who chose to continue to accrue benefits under the plan received benefits in accordance with plan provisions through June 30, 2015 as discussed further below. Participants who elected to cease accruals effective December 31, 1999 received the present value of their accrued benefit in an accrued pension account that is credited with interest based on the annual rate of interest on 30-year Treasury securities. These employees also receive certain enhanced employer contributions in the CNA 401k Plan.
Effective June 30, 2015, the Company eliminated future benefit accruals associated with the CNA Retirement Plan. Participants continuing to accrue benefits under the CNA Retirement Plan at that time are entitled to an accrued benefit payable based on their eligible compensation and accrued service through June 30, 2015. These affected participants now also receive enhanced employer contributions in the CNA 401k Plan similar to participants who elected to cease accruals effective December 31, 1999. Employees who elected to cease accruals effective December 31, 1999 were not affected by this curtailment.
CNA provides certain postretirement health care benefits to eligible retired employees, their covered dependents and their beneficiaries primarily through the CNA Health and Group Benefits Program. These postretirement benefits have largely been eliminated for active employees.

To determine the discount rate assumption as of the year-end measurement date for the CNA Retirement Plan and CNA Health and Group Benefits Program, the Company considered the estimated timing of plan benefit payments and available yields on high quality fixed income debt securities. For this purpose, high quality is considered a rating of Aa or better by Moody's Investors Service, Inc. (Moody's) or a rating of AA or better from Standard & Poor's (S&P). The Company reviewed several yield curves constructed using the cash flow characteristics of the plans as well as bond indices as of the measurement date. The trend of those data points was also considered.
In determining the expected long term rate of return on plan assets assumption for the CNA Retirement Plan, CNA considered the historical performance of the benefit plan investment portfolio as well as long term market return expectations based on the investment mix of the portfolio and the expected investment horizon.
The CNA Health and Group Benefits Program has limited its share of the health care trend rate to a cost-of-living adjustment of  i 4% per year. For all participants, the employer subsidy on health care costs will not increase by more than  i 4% per year. As a result, the assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation for the CNA Health and Group Benefits Program was  i  i  i 4 /  / % per year in 2020, 2019 and 2018.
CNA employs a total return approach whereby a mix of equity, limited partnerships and fixed maturity securities are used to maximize the long term return of retirement plan assets for a prudent level of risk and to manage cash flows according to plan requirements. The target allocation of plan assets is  i 40% to  i 60% invested in equity securities and limited partnerships, with the remainder primarily invested in fixed maturity securities. Alternative investments, including limited partnerships, are used to enhance risk adjusted long term returns while improving portfolio diversification. The intent of this strategy is to minimize the Company's expense related to funding the plan by generating investment returns that exceed the growth of the plan liabilities over the long run. Risk tolerance is established after careful consideration of the plan liabilities, plan funded status and corporate financial conditions.
As of December 31, 2020, the Plan had committed approximately $ i 190 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships. Derivatives may be used to gain market exposure in an efficient and timely manner. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.

The limited partnership investments held within the plan are recorded at fair value, which represents the plan's share of net asset value of each partnership, as determined by each limited partnership's general partner. Limited partnerships comprising  i 75% and  i 79% of the carrying value as of December 31, 2020 and 2019 employ hedge fund strategies that generate returns through investing in marketable securities in the public fixed income and equity markets and the remainder were primarily invested in private debt and equity. Within hedge fund strategies, approximately  i 69% were equity related,  i 27% pursued a multi-strategy approach and  i 4% were focused on distressed investments as of December 31, 2020.

In 2021, CNA expects to contribute $ i 6 million to its pension plans and $ i 1 million to its postretirement health care benefit plans.
Savings Plans
CNA sponsors savings plans, which are generally contributory plans that allow most employees to contribute a maximum of  i 50% of their eligible compensation, subject to certain limitations prescribed by the IRS. Effective January 1, 2020, the Company adopted amendments to its primary savings plan which impacted the Company contribution design. Under the current plan, the Company contributes matching amounts to participants amounting to  i 100% of the first  i 6% of eligible compensation contributed by the employee. In addition, eligible employees also receive a Company contribution of  i 5% of their eligible compensation, referred to as a basic contribution. Company contributions vest ratably over participants first  i five years of service.
Prior to January 1, 2020, the Company match was limited to  i 70% ( i 35% in the first year of employment) of the first  i 6% of eligible compensation contributed by the employee. The basic contribution was either  i 3% or  i 5%, depending on the age of the employee. Further, employees previously were eligible to receive additional discretionary contributions of up to  i 2% of eligible compensation and an additional Company match of up to  i 80% of the first  i 6% of eligible compensation contributed by the employee. These additional contributions were made at the discretion of management.
Benefit expense for the Company's savings plans was $ i 70 million, $ i 71 million and $ i 71 million for the years ended December 31, 2020, 2019 and 2018.

Note J.  i Stock-Based Compensation
The current CNAF Incentive Compensation Plan (the Plan) authorizes the grant of stock-based compensation to certain management personnel for up to  i 16 million shares of CNAF common stock. The Plan currently provides for awards of stock options, stock appreciation rights (SARs), restricted shares, restricted stock units (RSUs), performance-based RSUs and performance share units. The number of shares available for the granting of stock-based compensation under the Plan as of December 31, 2020 was approximately  i 5.9 million.
In 2016, CNA adopted the Annual Performance Share Plan (PSP). The PSP provides officers with an opportunity to earn an award based upon attainment of specific performance goals achieved over a  i one-year performance period. Awards are granted at the beginning of each performance year and are generally subject to a  i two-year cliff vesting period after the Company’s annual performance has been determined. Prior to the PSP, CNA issued performance share units under the Long Term Incentive Plan (LTI Plan). The LTI Plan had a  i three-year performance period and was settled during 2018. In both plans, the performance share units become payable within a range of  i 0% to  i 200% of the number of performance share units initially granted. Related to the transition to the PSP, CNA granted Special Supplemental Equity Awards (SSE) in 2016, which consisted of restricted stock units that fully vested in 2018.
Additionally, the Company may grant RSUs under the Plan in certain circumstances. These awards generally vest over a one to  i three-year service period following the grant date.
Stock-based compensation that is not fully vested prior to termination is generally forfeited upon termination, except in cases of retirement, death or disability, and as otherwise provided by contractual obligations. The fair value of stock-based compensation awards is based on the market value of the Company's common stock as of the date of grant, except for awards made to foreign participants, which is based on the current market value of the Company’s common stock. Payments made under the PSP and SSE are made entirely in shares of common stock granted under the Plan, except for awards made to foreign participants, which are paid in cash.
The Company recorded stock-based compensation expense related to the Plan of $ i 37 million, $ i 34 million and $ i 32 million for the years ended December 31, 2020, 2019 and 2018.

Note M.  i Stockholders’ Equity and Statutory Accounting Practices
Common Stock Dividends
There are no restrictions on the retained earnings or net income of CNAF with regard to payment of dividends to its stockholders. However, given the holding company nature of CNAF, its ability to pay a dividend is significantly dependent on the receipt of dividends from its subsidiaries, particularly CCC, which directly or indirectly owns the vast majority of all significant subsidiaries. See the Statutory Accounting Practices section below for a discussion of the regulatory restrictions on CCC's availability to pay dividends.
CNAF's ability to pay dividends may be indirectly limited by the minimum consolidated net worth covenant in the Company's line of credit agreement. See Note H to the Consolidated Financial Statements for further discussion of the Company's debt obligations.
Statutory Accounting Practices
CNAF’s insurance subsidiaries are domiciled in various jurisdictions. These subsidiaries prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions’ insurance regulators. Domestic prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners (NAIC) as well as state laws, regulations and general administrative rules. These statutory accounting principles vary in certain respects from GAAP. In converting from statutory accounting principles to GAAP, the more significant adjustments include deferral of policy acquisition costs and the inclusion of net unrealized holding gains or losses in stockholders’ equity relating to certain fixed maturity securities.
The Company has a prescribed practice as it relates to the accounting under Statement of Statutory Accounting Principles No. 62R (SSAP No. 62R), Property and Casualty Reinsurance, paragraphs 88 and 89 in conjunction with the 2010 LPT with NICO which is further discussed in Note E to the Consolidated Financial Statements.  The prescribed practice allows the Company to aggregate all third party A&EP reinsurance balances administered by NICO in Schedule F and to utilize the LPT as collateral for the underlying third party reinsurance balances for purposes of calculating the statutory reinsurance penalty. This prescribed practice increased statutory capital and surplus by $ i  i 91 /  million at December 31, 2020 and 2019.
The payment of dividends by CNAF's insurance subsidiaries without prior approval of the insurance department of each subsidiary’s domiciliary jurisdiction is generally limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective insurance regulator.
Dividends from CCC are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the 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 the 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 December 31, 2020, CCC is in a positive earned surplus position. The maximum allowable dividend CCC could pay during 2021 that would not be subject to the Department’s prior approval is $ i 1,070 million, less dividends paid during the preceding twelve months measured at that point in time. CCC paid dividends of $ i 975 million in 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.

 / 
CNAF’s domestic insurance subsidiaries are subject to risk-based capital (RBC) requirements. RBC is a method developed by the NAIC to determine the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of RBC specifies various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. The adequacy of a company's actual capital is evaluated by a comparison to the RBC results, as determined by the formula. Companies below minimum RBC requirements are classified within certain levels, each of which requires specified corrective action.
The statutory capital and surplus presented above for CCC was approximately  i 266% and  i 291% of company action level RBC as of December 31, 2020 and 2019. Company action level RBC is the level of RBC which triggers a heightened level of regulatory supervision. The statutory capital and surplus of the Company's foreign insurance subsidiaries, which is not significant to the overall statutory capital and surplus, also met or exceeded their respective regulatory and other capital requirements.

Note O.  i Business Segments
The Company's property and casualty commercial insurance operations are managed and reported in  i three business segments: Specialty, Commercial and International. These  i three segments are collectively referred to as Property & Casualty Operations. Specialty provides management and professional liability and other coverages through property and casualty products and services using a network of brokers, independent agencies and managing general underwriters. Commercial works with a network of brokers and independent agents to market a broad range of property and casualty insurance products to all types of insureds targeting small business, construction, middle markets and other commercial customers. The International segment underwrites property and casualty coverages on a global basis through a branch operation in Canada, a European business consisting of two insurance companies based in the U.K. and Luxembourg and Hardy, the Company's Lloyd's syndicate.
The Company's operations outside of Property & Casualty Operations are managed and reported in  i two segments: Life & Group and Corporate & Other. Life & Group primarily includes the results of the long term care business that is in run-off. Corporate & Other primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty business in run-off, including CNA Re and A&EP.
The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements. 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.
Approximately  i  i  i 9 /  / % of the Company's direct written premiums were derived from outside the United States for the years ended December 31, 2020, 2019 and 2018.
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 R.  i Non-Insurance Revenues from Contracts with Customers
Non-Insurance revenue is recognized when obligations under the terms of a contract with a customer are satisfied; generally this occurs over time as obligations are fulfilled. Revenue is measured as the amount of consideration the Company expects to receive in exchange for providing services.

The Company had deferred non-insurance warranty revenue balances of $ i 4.0 billion and $ i 3.8 billion reported in Deferred non-insurance warranty revenue as of December 31, 2020 and 2019. The increase in the deferred revenue balance for the year ended December 31, 2020 was primarily driven by deferrals outpacing revenue recognized in the period due to growth in the business. For the year ended December 31, 2020, the Company recognized $ i 1.1 billion of revenues that were included in the deferred revenue balance as of January 1, 2020. For the year ended December 31, 2019, the Company recognized $ i 971 million of revenues that were included in the deferred revenue balance as of January 1, 2019.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
CNA Financial Corporation
Chicago, Illinois
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of CNA Financial Corporation (an affiliate of Loews Corporation) and subsidiaries (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), cash flows, and stockholders' equity, for each of the three years in the period ended December 31, 2020, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
Change in Accounting Principle
As discussed in Note A to the financial statements, the Company changed its method of accounting for measurement of credit losses on financial instruments in 2020.
Basis for Opinions
The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Claim and claim adjustment expense reserves - Property & Casualty - Refer to Notes A and E to the consolidated financial statements.
Critical Audit Matter Description
The estimation of property and casualty claim and claim adjustment expense reserves (“P&C claim and claim adjustment expense reserves”), including those claims that are incurred but not reported, requires significant judgment. Estimating P&C claim and claim adjustment expense reserves is subject to a high degree of variability as it involves complex estimates that are generally derived using a variety of actuarial estimation techniques and numerous assumptions and expectations about future events, many of which are highly uncertain. Modest changes in judgments and assumptions can materially impact the valuation of these liabilities, particularly for claims with longer-tailed exposures such as workers’ compensation, general liability and professional liability claims.
Given the significant judgments made by management in estimating P&C claim and claim adjustment expense reserves, auditing P&C claim and claim adjustment expense reserves required a high degree of auditor judgment and an increased extent of effort, including the involvement of our actuarial specialists.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to P&C claim and claim adjustment expense reserves included the following, among others:
We tested the effectiveness of controls related to the determination of P&C claim and claim adjustment expense reserves, including those controls related to the estimation of and management’s review of P&C claim and claim adjustment expense reserves.
We tested the underlying data, including historical claims, that served as the basis for the actuarial analyses, to test that the inputs to the actuarial estimates were accurate and complete.
With the assistance of our actuarial specialists:
134

Table of Contents
We developed a range of independent estimates of P&C claim and claim adjustment expense reserves and compared our estimates to the recorded reserves.
We compared our prior year estimates of expected incurred losses to actual experience during the most recent year to identify potential bias in the Company’s determination of P&C claim and claim adjustment expense reserves.
Future policy benefit reserves - Long Term Care - Refer to Notes A and E to the consolidated financial statements.
Critical Audit Matter Description
The estimation of long term care future policy benefit reserves (“LTC future policy benefit reserves”) requires significant judgment in the selection of key assumptions, including morbidity, persistency (inclusive of mortality), discount rate and future premium rate increases.
A gross premium valuation (“GPV”) is performed annually to assess the adequacy of the LTC future policy benefit reserves. The actuarial assumptions underlying the recorded LTC future policy benefit reserves are “locked-in” absent an indicated premium deficiency. If the GPV indicates the recorded LTC future policy benefit reserves are not adequate (i.e. a premium deficiency exists), the assumptions are “unlocked” and the LTC future policy benefit reserves are increased to eliminate the premium deficiency.
Estimating future experience for long term care policies is subject to significant estimation risk as the required projection period spans several decades. Morbidity and persistency experience can be volatile while discount rates and premium rate increases can be difficult to predict. Modest changes in each of these assumptions can materially impact the valuation of these liabilities.
Given the significant judgments made by management in estimating LTC future policy benefit reserves, auditing LTC future policy benefit reserves required a high degree of auditor judgment and an increased extent of effort, including the involvement of our actuarial specialists.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to LTC future policy benefit reserves included the following, among others:
We tested the effectiveness of controls related to the determination of LTC future policy benefit reserves, including those controls related to the estimation of and management’s review of LTC future policy benefit reserves.
We tested the underlying data, including demographic and historical claims data, that served as the basis for the actuarial analyses, to test that the inputs to the actuarial estimates were accurate and complete.
With the assistance of our actuarial specialists:
We independently recalculated a sample of LTC future policy benefit reserves and compared our estimates to the recorded reserves.
We evaluated the key assumptions applied in the GPV analysis, including comparing those assumptions to the Company’s historical experience, underlying portfolio yield and market data.
We assessed the Company’s projection of future cash flows to evaluate the reasonableness of the charge related to unlocking LTC future policy benefit reserves to recognize a premium deficiency.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of CNA Financial Corporation (CNAF or the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. CNAF's internal control system was designed to provide reasonable assurance to the Company's management, its Audit Committee and Board of Directors regarding the preparation and fair presentation of published financial statements.
There are inherent limitations to the effectiveness of any internal control or system of control, however well designed, including the possibility of human error and the possible circumvention or overriding of such controls or systems. Moreover, because of changing conditions the reliability of internal controls may vary over time. As a result even effective internal controls can provide no more than reasonable assurance with respect to the accuracy and completeness of financial statements and their process of preparation.
CNAF management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2020. In making this assessment, it has used the criteria set forth by the 2013 Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. Based on those criteria and our assessment we believe that, as of December 31, 2020, the Company's internal control over financial reporting was effective.
CNAF's independent registered public accountant, Deloitte & Touche LLP, has issued an audit report on the Company's internal control over financial reporting. This report appears on page 133.

Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective.
