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

OVERVIEW

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

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements included under Part I, Item 1 of this Form 10-Q, and Item 1A Risk Factors and Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2025.

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 gains or losses resulting from pension settlement transactions. Net investment gains or losses are excluded from the calculation of core income (loss) because they are generally driven by economic factors that are not necessarily reflective of our primary operations. The calculation of core income (loss) excludes gains or losses resulting from pension settlement transactions as they result from decisions regarding our defined benefit pension plans which are unrelated to our primary operations. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure and management believes some investors may find this measure useful to evaluate our primary operations. See further discussion regarding how we manage our business in Note J to the Condensed Consolidated Financial Statements included under Part I, Item 1. For reconciliations of non-GAAP measures to the most comparable GAAP measures and other information, please refer herein and/or to our most recent Annual Report on Form 10-K on file with the Securities and Exchange Commission.

In evaluating the results of our Specialty, Commercial and International segments, we utilize the loss ratio, the underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophe-related reinstatement premiums, catastrophe losses and development-related items from the loss ratio. Development-related items represent net prior year loss reserve and premium development, and include the effects of interest accretion and change in allowance for uncollectible reinsurance. 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 ratio, the expense ratio and the dividend ratio. The underlying combined ratio is the sum of the underlying loss ratio, the expense ratio and the dividend ratio. The underlying loss ratio and the underlying combined ratio are deemed to be non-GAAP financial measures, and management believes some investors may find these ratios useful to evaluate our underwriting performance since they remove the impact of catastrophes which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

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 and Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1.

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. Exposure represents the measure of risk used in the pricing of the insurance product. The change in exposure represents the change in premium dollars on policies that renew as a result of the change in risk of the policy. Retention represents the percentage of premium dollars renewed, excluding rate and exposure changes, in comparison to the expiring premium dollars from policies available to renew. New business represents premiums from policies written with new customers and additional policies written with existing customers.

Table of Contents

We use underwriting gain (loss) and underlying underwriting gain (loss), calculated using GAAP financial results, to monitor our insurance operations. Underwriting gain (loss) is deemed to be a non-GAAP financial measure and is calculated pretax as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and insurance related administrative expenses. Net income (loss) is the most directly comparable GAAP measure. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, which are managed separately from our investing activities. Underlying underwriting gain (loss) is also deemed to be a non-GAAP financial measure, and represents pretax underwriting gain (loss) excluding catastrophe-related reinstatement premiums, catastrophe losses and development-related items. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, excluding the impact of catastrophes, which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

OVERVIEW

The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, 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 the reserves are recorded as Future policy benefits reserves as discussed below. The reserve for unearned premiums represents the portion of premiums written related to the unexpired terms of coverage. If our recorded reserves are insufficient to cover our estimated ultimate unpaid liability, we may need to increase our insurance reserves. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.

Long-Term Care Reserves

Future policy benefits reserves for our long-term care policies are based on certain actuarial assumptions, including morbidity, persistency, premium rate actions and expenses. 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 increase reserves. The reserves are discounted using upper-medium grade fixed income instrument yields as of each reporting date. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.

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.

Table of Contents

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.

RESERVES - ESTIMATES AND UNCERTAINTIES

The level of 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, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note E and F 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. 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 increases.

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 and the deferred retroactive reinsurance gains and the amount of remaining reinsurance limit.

Establishing Property & Casualty Reserve Estimates

In developing claim and claim adjustment expense 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 typically 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 economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, 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, 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 can be 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 the 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 reserve differs 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.

Table of Contents

The key assumptions fundamental to the reserving process often vary for different reserve groups and accident or policy years. Some of these assumptions are explicit and required by specific methods, while most are implicit and cannot be precisely quantified. An example of an explicit assumption is the pattern used in the paid or incurred development method. However, this pattern is based on several implicit assumptions, such as the impact of inflation on claim costs and the rate at which claim professionals make claim payments and close claims. Consequently, the effect of changes in assumptions on reserve estimates typically cannot be specifically quantified, and these changes cannot be tracked over time.

Our recorded reserves are management's best estimate. To indicate the variability associated with our recorded reserves, the following discussion provides a sensitivity analysis showing the approximate estimated impact of variations in significant factors affecting our reserve estimates for particular types of business. These significant factors are those we believe could most likely materially affect the reserves. This discussion covers the major types of business for which we believe a material deviation in 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 in the discussion. Additionally, there can be no assurance that other factors and assumptions will not have a material impact on our reserves.

The areas for which we believe a significant deviation to our recorded reserves is reasonably possible are (i) medical professional liability; (ii) other professional liability and management liability; (iii) general liability; (iv) workers' compensation, and (v) commercial automobile liability.

Medical professional liability, other professional liability and management liability, and general liability all have long development patterns with relatively immature paid data. This requires considerable judgment regarding development to ultimate losses and inherent risks due to economic, social and medical inflation, as well as legal fees, judicial decisions, legislative changes and other factors. The following table reflects the impact on our recorded reserves (which could be favorable or unfavorable) of changing the ultimate losses by one percentage point in the long-tail development:

As of December 31, 2025Impact
Recorded Reserve (In billions)Amount (+/-) (In millions)Percent (+/-)
Medical Professional Liability$1.5$1208.0%
Other Professional Liability and Management Liability4.12406.0
General Liability4.82806.0

Workers' compensation also requires considerable judgment given its long development pattern and the impacts of medical inflation, the cost of wage replacement, expected claimant lifetimes, judicial decisions, legislative changes and other factors. Adjusting the ultimate losses by one percentage point change in the long-tail development would increase or decrease the recorded reserve of $3.5 billion as of December 31, 2025 by approximately $240 million, or 7% of the recorded reserves.

Commercial automobile liability is also considered long-tail; however, the frequency of claims and severity of loss assumptions for the latest few accident years are significantly influenced by social and economic inflation, driving habits and attorney involvement. If these trends accelerate beyond expectations, there may be significant deviation in our recorded reserves. Our recorded reserves for commercial automobile liability were $1.6 billion as of December 31, 2025. The following table reflects the impact on our recorded reserves of increasing the frequency and severity assumptions in the ultimate commercial automobile liability losses on the three most recent accident years:

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, 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 may 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 future policy benefit reserves for our long-term care policies. Future policy benefit reserves for long-term care policies relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits. In developing the future policy benefit reserves, our actuaries perform a reserve review on an annual basis. During the annual review, historical policyholder morbidity, persistency, premium rate actions and expense experience is reviewed and compared to the current best estimate actuarial assumption set for potential revision. On a quarterly basis, our actuaries perform experience studies that monitor the appropriateness of best estimate actuarial assumptions against emerging experience to assess whether any updates to those assumptions are warranted. The determination of these reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policies. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk. Future policy benefit reserves are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.

In addition, claim and claim adjustment expense reserves are maintained for our structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for our structured settlement obligations, our actuaries monitor mortality and expense 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 structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.

The actuarial assumptions related to future policy benefit reserves for long-term care policies that management believes are subject to the most variability are morbidity, persistency and premium rate actions. 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. Premium rate actions 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.

Table of Contents

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our liability for future policyholder benefits (LFPB) reserve assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each long-term care product. The impact of each sensitivity is discrete and does not reflect the impact one factor may have on another or the mitigating impact from management actions, which may include additional premium rate actions. 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. The estimated impacts to results of operations in the table below are after consideration of any net premium ratio impacts.

Estimated reduction to pretax income

As part of the annual reserve review completed in the third quarter of each year, statutory long-term care reserve adequacy is evaluated via premium deficiency testing, by comparing carried statutory reserves with our best estimate reserves, which incorporates best estimate discount rate and liability assumptions in its determination. Statutory margin is the excess of carried reserves over best estimate reserves. As of September 30, 2025, statutory long-term care margin increased to $1.5 billion from $1.4 billion.

CATASTROPHES AND RELATED REINSURANCE

Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, tornadoes, 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 United States of America (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 $240 million and $358 million for the years ended December 31, 2025 and 2024. Catastrophe losses for the years ended December 31, 2025 and 2024 were driven by severe weather related events, including $64 million for the California wildfires in 2025 and $71 million for Hurricane Helene and $33 million for Hurricane Milton in 2024.

We use various analyses and methods, including using one of the industry standard natural catastrophe models, to estimate hurricane and earthquake losses at various return periods and to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure through the purchase of catastrophe reinsurance and utilize various reinsurance programs to mitigate catastrophe losses, including excess-of-loss occurrence and aggregate treaties covering property and workers’ compensation, a property quota share treaty and the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA), as well as individual risk agreements that reinsure from losses from specific classes or lines of business. We conduct an ongoing review of our risk and catastrophe reinsurance 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, 2026.

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. The treaty has a term of June 1, 2025 to June 1, 2026 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $275 million up to $1.4 billion for all losses. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological, chemical or radiation event. 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, 2026 to January 1, 2027 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 $775 million of coverage for the accumulation of covered losses related to terrorism events above our per occurrence retention of $25 million. Of the $775 million in terrorism coverage, $200 million is provided for nuclear, biological, chemical and radiation events. All layers of the treaty provide for one full reinstatement.

Terrorism Risk Insurance Program Reauthorization Act of 2019

Our principal reinsurance protection against large-scale terrorist attacks, including nuclear, biological, chemical or radiation events, 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 and the U.S. Attorney General for losses that exceed a threshold of $200 million industry-wide for the calendar year 2026. Under the current provisions of the program, in 2026, 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 2025 earned premiums, our estimated deductible under the program is

$1.4 billion for 2026. 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.

2025 Compared with 2024

Net income was $1,278 million for 2025 as compared with $959 million for 2024, which included a $293 million after-tax loss from pension settlement transactions. Pension settlement transactions are further discussed in Note J to the Consolidated Financial Statements included under Item 8. Core income increased $26 million in 2025 as compared with 2024. Core income for our Property & Casualty Operations increased $115 million driven by improved current accident year underwriting results and higher net investment income partially offset by unfavorable net prior period development. Core loss for our Life & Group segment increased $21 million, while core loss for our Corporate & Other segment increased $68 million.

Catastrophe losses were $240 million and $358 million for 2025 and 2024. Catastrophe losses for 2025 and 2024 were driven by severe weather related events, including $64 million for the California wildfires in 2025 and $71 million for Hurricane Helene and $33 million for Hurricane Milton in 2024. Unfavorable net prior year loss reserve development of $185 million and $48 million was recorded in 2025 and 2024 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 retail and wholesale brokers, independent agents and managing general underwriters. Commercial works with a network of retail and wholesale 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 market 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 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 A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.

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 gains or losses resulting from pension settlement transactions. Net investment gains or losses are excluded from the calculation of core income (loss) because they are generally driven by economic factors that are not necessarily reflective of our primary operations. The calculation of core income (loss) excludes gains or losses resulting from pension settlement transactions as they result from decisions regarding our defined benefit pension plans which are unrelated to our primary operations. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure and management believes some investors may find this measure useful to evaluate our primary operations. See further discussion regarding how we manage our business in Note N to the Consolidated Financial Statements included under Item 8. For reconciliations of non-GAAP measures to the most comparable GAAP measures and other information, please see below and in Note N 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 underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophe losses and development-related items from the loss ratio. Development-related items represents net prior year loss reserve and premium development, and includes the effects of interest accretion and change in allowance for uncollectible reinsurance. 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 ratio, the expense ratio and the dividend ratio. The underlying combined ratio is the sum of the underlying loss ratio, the expense ratio and the dividend ratio. The underlying loss ratio and the underlying combined ratio are deemed to be non-GAAP financial measures, and management believes some investors may find these ratios useful to evaluate our underwriting performance since they remove the impact of catastrophe losses which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

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 and Note F to the Consolidated Financial Statements included under Item 8.

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

Table of Contents

excluding exposure change. Exposure represents the measure of risk used in the pricing of the insurance product. The change in exposure represents the change in premium dollars on policies that renew as a result of the change in risk of the policy. Retention represents the percentage of premium dollars renewed, excluding rate and exposure changes, in comparison to the expiring premium dollars from policies available to renew. New business represents premiums from policies written with new customers and additional policies written with existing customers.

We use underwriting gain (loss) and underlying underwriting gain (loss), calculated using GAAP financial results, to monitor our insurance operations. Underwriting gain (loss) is deemed to be a non-GAAP financial measure and is calculated pretax as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and insurance related administrative expenses. Net income (loss) is the most directly comparable GAAP measure. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, which are managed separately from our investing activities. Underlying underwriting gain (loss) is also deemed to be a non-GAAP financial measure, and represents pretax underwriting gain (loss) excluding catastrophe losses and development-related items. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, excluding the impact of catastrophe losses, which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

2025 Compared with 2024

Net written premiums for Specialty increased $70 million in 2025 as compared with 2024 driven by rate partially offset by lower retention. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income decreased $57 million in 2025 as compared with 2024 primarily due to unfavorable net prior year loss reserve development in 2025 compared with favorable net prior year loss reserve development in 2024 and lower underlying underwriting results partially offset by higher net investment income.

The combined ratio of 95.3% increased 2.7 points in 2025 as compared with 2024 due to a 2.0 point increase in the loss ratio and a 0.7 point increase in the expense ratio. The increase in the loss ratio was due to unfavorable net prior year loss reserve development recorded in 2025 and an increase in the underlying loss ratio, primarily driven by continued pricing pressure in management liability lines. The increase in the expense ratio was driven by higher employee related costs and a non-recurring technology charge partially offset by higher net earned premiums. There were no catastrophe losses for 2025 or 2024.

Unfavorable net prior year loss reserve development of $37 million was recorded in 2025 compared with $9 million of favorable net prior year loss reserve development recorded in 2024. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2025 Compared with 2024

Net written premiums for Commercial increased $352 million in 2025 as compared with 2024 driven by favorable renewal premium change, inclusive of rate, partially offset by lower retention. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $118 million in 2025 as compared with 2024, driven by lower catastrophe losses, improved underlying underwriting results and higher net investment income partially offset by unfavorable net prior year loss reserve development.

The combined ratio of 95.2% improved 1.5 points in 2025 as compared with 2024 due to a 1.1 point improvement in the expense ratio and a 0.4 point improvement in the loss ratio. The improvement in the expense ratio was primarily driven by higher net earned premiums and a lower acquisition ratio. The improvement in the loss ratio was driven by lower catastrophe losses partially offset by unfavorable net prior year loss reserve development and an increase in the underlying loss ratio related to social inflation impacted lines. Catastrophe losses were $217 million, or 3.8 points of the loss ratio, for 2025, as compared with $318 million, or 6.2 points of the loss ratio, for 2024.

2025 Compared with 2024

Core loss increased $21 million in 2025 as compared with 2024 primarily due to lower net investment income from limited partnerships. Both years are inclusive of assumption updates as a result of the annual reserve review completed in the third quarter of each year.

The cash flow assumption updates from the annual reserve review for 2025 and 2024 resulted in a pretax increase in long-term care reserves of $7 million and $15 million.

The annual structured settlement reserve review resulted in a pretax increase in claim reserves of $2 million for 2025 and a reduction in claim reserves of $9 million for 2024.

The current year also includes an unfavorable non-economic impact related to the A&EP LPT. The prior year included $16 million of after-tax charges related to office consolidation.

The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT resulted in an after-tax charge of $36 million and $6 million in 2025 and 2024, both of which have no economic impact.

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 2025, net cash provided by operating activities was $2,490 million as compared with $2,571 million for 2024. The decrease in cash provided by operating activities was driven by an increase in net claim payments and higher operating expenses, partially offset by an increase in premiums collected and higher cash from investment earnings.

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.

For 2025, net cash used by investing activities was $1,449 million as compared with $1,317 million for 2024. Net cash used or provided 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 our common stock.

For 2025, net cash used by financing activities was $1,104 million as compared with $1,117 million for 2024. Financing activities for the periods presented include:

•In 2025, we issued $500 million of 5.20% notes due August 15, 2035 and repaid at par the $500 million outstanding aggregate principal balance of our 4.50% senior notes in advance of their March 1, 2026 maturity date.

•In 2025, we paid dividends of $1,047 million and repurchased 700,000 shares of common stock at an aggregate cost of $34 million.

•In 2024, we issued $500 million of 5.125% notes due February 15, 2034 and repaid the $550 million outstanding aggregate principal balance of our 3.95% senior notes which came due May 15, 2024.

•In 2024, we paid dividends of $1,025 million and repurchased 450,000 shares of our common stock at an aggregate cost of $20 million.

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 $1,115 million and $995 million to CNAF during 2025 and 2024.

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

Common Stock Dividends

Cash dividends of $3.84 per share on our common stock, including a special cash dividend of $2.00 per share, were declared and paid in 2025. On February 6, 2026, our Board of Directors declared a quarterly cash dividend of $0.48 per share and a special cash dividend of $2.00 per share, payable March 12, 2026 to stockholders of record on February 23, 2026. 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 satisfy our 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.

Commitments, Contingencies and Guarantees

We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

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, see Note A to the Consolidated Financial Statements included under Item 8.

RECENT LEGISLATION

On July 4, 2025, H.R. 1, “An Act to provide for reconciliation pursuant to title II of H. Con. Res. 14,” commonly referred to as the One Big Beautiful Bill Act (OBBBA), was enacted. The OBBBA includes significant federal tax law changes which, among other impacts, modify and make permanent certain business tax provisions originally enacted in the 2017 Tax Cuts and Jobs Act. The provisions of the OBBBA have not had a material impact on our results of operations or financial condition. The OBBBA is subject to further clarification from the issuance of future technical guidance by the U.S. Department of Treasury.

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 conduct; 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 statements. We cannot control many of these risks and uncertainties. Material risks and uncertainties are addressed in Part I, Item IA Risk Factors and 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 of future increases, which would be reflected in the results of operations in the period that the need for such adjustment is determined;

•the risk that the other parties to the transactions in which, subject to certain limitations, we ceded our legacy A&EP and EWC liabilities, respectively, will not fully perform their respective obligations to CNA, the uncertainty in estimating loss reserves for A&EP and EWC liabilities and the possible continued exposure of CNA to liabilities for A&EP and EWC claims that are not covered under the terms of the respective transactions; and

•the performance of reinsurance companies under reinsurance contracts with us.

Industry and General Market Factors

•general economic and business conditions, including potential recessionary conditions that may decrease the size and number of our insurance customers and create losses in our lines of business, and inflationary pressures on medical care costs, construction costs and other economic sectors;

•the effect of new tariffs and changes in tariffs, as well as significant uncertainty surrounding U.S. tariff policy generally, and any retaliatory tariffs, may adversely impact the economic environment, inflation expectations and certain loss costs, and may result in decreases in the size and number of our insurance customers;

•the effects of social inflation, including frequency of nuclear verdicts and increased litigation activity, on the severity of claims;

•the effects on the frequency of claims of reviver statutes that extend, or eliminate, the statute of limitations for the reporting of claims, including statutes passed in certain states with respect to sexual abuse;

OVERVIEW

The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, 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 the reserves are recorded as Future policy benefits reserves as discussed below. The reserve for unearned premiums represents the portion of premiums written related to the unexpired terms of coverage. If our recorded reserves are insufficient to cover our estimated ultimate unpaid liability, we may need to increase our insurance reserves. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.

Long-Term Care Reserves

Future policy benefits reserves for our long-term care policies are based on certain actuarial assumptions, including morbidity, persistency, anticipated future premium rate increases and expenses. 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 increase reserves. The reserves are discounted using upper-medium grade fixed income instrument yields as of each reporting date. In addition, we may not receive regulatory approval for the level of premium rate increases we request. 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 H 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

21

Table of Contents

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. 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.

RESERVES - ESTIMATES AND UNCERTAINTIES

The level of 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, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note E and F 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. 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 increases.

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 and the deferred retroactive reinsurance gains and the amount of remaining reinsurance limit.

Establishing Property & Casualty Reserve Estimates

In developing claim and claim adjustment expense 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 typically 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

23

Table of Contents

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 economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, 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, 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 can be 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 the 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 reserve differs 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 areas for which we believe a significant deviation to our net reserves is reasonably possible are (i) professional liability, management liability (including medical professional liability) and surety products; (ii) workers' compensation; (iii) general liability, and (iv) commercial auto liability.

Professional liability, management liability and surety products include US 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), errors and omissions (E&O), employment practices, fiduciary, fidelity, cyber 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 $500 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 $5.8 billion as of December 31, 2024.

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 $250 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 $250 million. Our net reserves for workers' compensation were approximately $3.5 billion as of December 31, 2024.

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 $300 million. If the estimated claim severity for general liability decreases by 3%, we estimate that our net reserves would decrease by approximately $150 million. Our net reserves for general liability were approximately $4.9 billion as of December 31, 2024.

Commercial auto liability is also considered long-tail; however, both the frequency of claims and severity of loss assumptions for the latest few accident years are significantly influenced by social inflation, economic inflation, driving habits and attorney involvement. If these trends accelerate beyond expectations, there may be significant deviation in our net reserves. If the estimated auto liability claim severity were to increase 5% and frequency were to increase 1% on the three most recent accident years, we estimate that our net reserves would increase by approximately $90 million. Our net reserves for commercial auto were approximately $1.2 billion as of December 31, 2024.

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, 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 may 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 future policy benefit reserves for our long-term care policies. Future policy benefit reserves for long-term care policies relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits. In developing the future policy benefit reserves, our actuaries perform a reserve review on an annual basis. During the annual review, historical policyholder morbidity, persistency, anticipated future premium rate increases and expense experience is reviewed and compared to the current best estimate actuarial assumption set for potential revision. On a quarterly basis, our actuaries perform experience studies that monitor the appropriateness of best estimate actuarial assumptions against emerging experience to assess whether any updates to those assumptions are warranted. The determination of these reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policies. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk. Future policy benefit reserves are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.

In addition, claim and claim adjustment expense reserves are maintained for our structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for our structured settlement obligations, our actuaries monitor mortality and expense 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 structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.

The actuarial assumptions related to future policy benefit reserves for long-term care policies that management believes are subject to the most variability are morbidity, persistency 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. 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-

27

Table of Contents

term care reserves may be subject to material increases if actual experience develops adversely to our expectations.

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our liability for future policyholder benefits (LFPB) reserve assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each long-term care product. The impact of each sensitivity is discrete and does not reflect the impact one factor may have on another or the mitigating impact from management actions, which may include additional future premium rate increases. 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. The estimated impacts to results of operations in the table below are after consideration of any net premium ratio impacts.

Morbidity:
2.5% increase in morbidity$290
5% increase in morbidity590

10% decrease in active life mortality and lapse310
Premium Rate Actions:
25% decrease in anticipated future premium rate increases$10
50% decrease in anticipated future premium rate increases20

As part of the annual reserve review, statutory long-term care reserve adequacy is evaluated via premium deficiency testing, by comparing carried statutory reserves with our best estimate reserves, which incorporates best estimate discount rate and liability assumptions in its determination. Statutory margin is the excess of carried reserves over best estimate reserves. As of September 30, 2024, statutory long-term care margin increased to $1.4 billion from $1.3 billion, primarily driven by a more favorable interest rate environment resulting in a higher yielding investment portfolio.

CATASTROPHES AND RELATED REINSURANCE

Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, tornadoes, 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 United States of America (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 $358 million and $236 million for the years ended December 31, 2024 and 2023. Catastrophe losses for the years ended December 31, 2024 and 2023 were driven by severe weather related events, including $71 million for Hurricane Helene and $33 million for Hurricane Milton in 2024.

We use various analyses and methods, including using one of the industry standard natural catastrophe models, to estimate hurricane and earthquake losses at various return periods and to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure through the purchase of catastrophe reinsurance and utilize various reinsurance programs to mitigate catastrophe losses, including excess-of-loss occurrence and aggregate treaties covering property and workers’ compensation, a property quota share treaty and the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA), as well as individual risk agreements that reinsure from losses from specific classes or lines of business. We conduct an ongoing review of our risk and catastrophe reinsurance 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, 2025.

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. The treaty has a term of June 1, 2024 to June 1, 2025 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $250 million up to $1.4 billion for all losses. 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, 2025 to January 1, 2026 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 $775 million of coverage for the accumulation of covered losses related to terrorism events above our per occurrence retention of $25 million. Of the $775 million in terrorism coverage, $200 million is provided for nuclear, biological chemical and radiation events. All layers of the treaty provide for one full reinstatement.

Terrorism Risk Insurance Program Reauthorization Act of 2019

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 2025. Under the current provisions of the program, in 2025, 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 2024 earned premiums, our estimated deductible under the program is $1.2 billion for 2025. If an act of terrorism or

29

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.

2024 Compared with 2023

Net income was $959 million for 2024, which includes a $293 million after-tax loss from pension settlement transactions, as compared with $1,205 million for 2023. Pension settlement transactions are further discussed in Note J to the Consolidated Financial Statements included under Item 8. Core income increased $32 million in 2024 as compared with 2023. Core income for our Property & Casualty Operations increased $44 million driven by higher net investment income and improved underlying underwriting results partially offset by higher catastrophe losses and an unfavorable impact from changes in foreign currency exchange rates. Core loss for our Life & Group segment decreased $25 million, while core loss for our Corporate & Other segment increased $37 million.

Catastrophe losses were $358 million and $236 million for 2024 and 2023, primarily driven by severe weather related events, including $71 million for Hurricane Helene and $33 million for Hurricane Milton in 2024. Unfavorable net prior year loss reserve development of $48 million was recorded in each of 2024 and 2023 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 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, A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.

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 gains or losses resulting from pension settlement transactions. Net investment gains or losses are excluded from the calculation of core income (loss) because they are generally driven by economic factors that are not necessarily reflective of our primary operations. The calculation of core income (loss) excludes gains or losses resulting from pension settlement transactions as they result from decisions regarding our defined benefit pension plans which are unrelated to our primary operations. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure and management believes some investors may find this measure useful to evaluate our primary operations. See further discussion regarding how we manage our business in Note P to the Consolidated Financial Statements included under Item 8. For reconciliations of non-GAAP measures to the most comparable GAAP measures and other information, please see below and Note P 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 underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophe losses and development-related items from the loss ratio. Development-related items represents net prior year loss reserve and premium development, and includes the effects of interest accretion and change in allowance for uncollectible reinsurance and deductible amounts. 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 ratio, the expense ratio and the dividend ratio. The underlying combined ratio is the sum of the underlying loss ratio, the expense ratio and the dividend ratio. The underlying loss ratio and the underlying combined ratio are deemed to be non-GAAP financial measures, and management believes some investors may find these ratios useful to evaluate our underwriting performance since they remove the impact of catastrophe losses which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

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 and Note F to the Consolidated Financial Statements included under Item 8.

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. Exposure represents the measure of risk used in the pricing of the insurance

product. The change in exposure represents the change in premium dollars on policies that renew as a result of the change in risk of the policy. Retention represents the percentage of premium dollars renewed, excluding rate and exposure changes, in comparison to the expiring premium dollars from policies available to renew. 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.

We use underwriting gain (loss) and underlying underwriting gain (loss), calculated using GAAP financial results, to monitor our insurance operations. Underwriting gain (loss) is deemed to be a non-GAAP financial measure and is calculated pretax as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and insurance related administrative expenses. Net income (loss) is the most directly comparable GAAP measure. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, which are managed separately from our investing activities. Underlying underwriting gain (loss) is also deemed to be a non-GAAP financial measure, and represents pretax underwriting gain (loss) excluding catastrophe losses and development-related items. Management believes some investors may find this measure useful to evaluate the profitability, before tax, derived from our underwriting activities, excluding the impact of catastrophe losses, which are unpredictable as to timing and amount, and development-related items as they are not indicative of our current year underwriting performance.

Gross written premiums, excluding third-party captives, for Specialty increased $95 million in 2024 as compared with 2023 driven by retention and favorable renewal premium change. Net written premiums for Specialty increased $116 million in 2024 as compared with 2023. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income decreased $14 million in 2024 as compared with 2023 primarily due to lower underlying underwriting results and higher claim costs in our non-insurance auto warranty business partially offset by higher net investment income.

The combined ratio of 92.6% increased 2.2 points in 2024 as compared with 2023 primarily due to a 1.3 point increase in the loss ratio and a 0.8 point increase in the expense ratio. The increase in the loss ratio was primarily due to an increase in the underlying loss ratio, primarily driven by continued pricing pressure in management liability lines over the last several quarters. The increase in the expense ratio was driven by lower net earned premium growth. There were no catastrophe losses for 2024 and 2023.

Favorable net prior year loss reserve development of $9 million and $14 million was recorded in 2024 and 2023. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2024 Compared with 2023

Gross written premiums for Commercial increased $844 million in 2024 as compared with 2023 driven by favorable renewal premium change, rate and higher new business. Net written premiums for Commercial increased $589 million in 2024 as compared with 2023. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $50 million in 2024 as compared with 2023, driven by improved underlying underwriting results and higher net investment income partially offset by higher catastrophe losses.

The combined ratio of 96.7% increased 0.7 points in 2024 as compared with 2023 due to a 2.4 point increase in the loss ratio partially offset by a 1.7 point improvement in the expense ratio. The increase in the loss ratio was primarily driven by higher catastrophe losses and an increase in the underlying loss ratio, driven by the continuation of elevated loss cost trends in commercial auto and mix of business. Catastrophe losses were $318 million, or 6.2 points of the loss ratio, for 2024, as compared with $207 million, or 4.5 points of the loss ratio, for 2023.

2024 Compared with 2023

Gross written premiums for International decreased $2 million in 2024 as compared with 2023. Excluding the effect of foreign currency exchange rates, gross written premiums decreased $14 million driven by lower new business and rate. Net written premiums for International increased $25 million in 2024 as compared with 2023. Excluding the effect of foreign currency exchange rates, net written premiums increased $21 million as compared with 2023 driven by favorable adjustments on prior year reinsurance treaties, in the current year. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $8 million in 2024 as compared with 2023 driven by higher net investment income and favorable net prior year loss reserve development in the current year compared with unfavorable net prior year loss reserve development in the prior year, partially offset by lower underlying underwriting results and higher catastrophe losses.

Table of Contents

The combined ratio of 94.0% increased 1.4 points in 2024 as compared with 2023 due to a 1.9 point increase in the expense ratio partially offset by a 0.5 point improvement in the loss ratio. The increase in the expense ratio was driven by higher employee related costs and a favorable reinsurance acquisition related catch-up adjustment recorded in the prior year, partially offset by higher net earned premiums. The improvement in the loss ratio was primarily driven by favorable net prior year loss reserve development partially offset by higher catastrophe losses. Catastrophe losses were $40 million, or 3.2 points of the loss ratio, for 2024, as compared with $29 million, or 2.5 points of the loss ratio, for 2023.

2024 Compared with 2023

Core loss decreased $25 million in 2024 as compared with 2023 primarily due to higher net investment income. Both years are inclusive of assumption updates as a result of the annual reserve review completed in the third quarter of each year.

The cash flow assumption updates from the annual reserve review for 2024 and 2023 resulted in a pretax increase in long-term care reserves of $15 million and $8 million.

The annual structured settlement reserve review resulted in a pretax reduction in claim reserves of $9 million and $6 million for 2024 and 2023.

2024 Compared with 2023

Core loss increased $37 million for 2024 as compared with 2023. The current year includes higher corporate expenses as a result of continued investments in technology and an unfavorable non-economic impact related to the A&EP LPT. The current year also includes a $62 million after-tax charge related to unfavorable net prior year loss reserve development for legacy mass tort claims compared with a $56 million after-tax charge for legacy mass tort claims in the prior year.

The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT resulted in an after-tax charge of $6 million in 2024 compared to an after-tax benefit of $6 million in 2023, both of which have no economic impact.

Included in 2024 results is $16 million of after-tax charges related to office consolidation compared with $19 million of after-tax charges in the prior year.

Commercial Real Estate

Our investment portfolio has exposure to the commercial real estate sector primarily through our fixed maturity securities and mortgage loan portfolios. The performance of these assets is dependent on a number of factors, including the performance of the underlying collateral (which is influenced by cash flows from underlying property leases), changes in the fair value of collateral, refinancing risk, and the creditworthiness of tenants of credit tenant loan properties (where lease payments directly service the loan).

Within our fixed maturity securities portfolio, our exposure is primarily through our commercial mortgage-backed securities portfolio and our corporate and other bonds portfolio, which contains obligations of real estate investment trust (REIT) issuers. Commercial mortgage-backed securities include both single asset, single borrower collateral that is securitized independently and conduit collateral that is securitized in diversified pools.

Mortgage loans are commercial in nature and are carried at unpaid principal balance, net of unamortized fees and an allowance for expected credit losses. 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). This assessment utilizes historical credit loss experience adjusted to reflect current conditions and reasonable and supportable forecasts. As of December 31, 2024 and 2023 the allowance for expected credit losses on our mortgage portfolio was $35 million, or 3.3% of our amortized cost basis.

In addition to our mortgage loan portfolio, we invest in securitized credit tenant loans and ground lease financings that are classified as fixed maturity securities and are largely investment grade quality. As of December 31, 2024 and 2023, these holdings had an estimated fair value of $471 million and $479 million, and net unrealized losses of $118 million and $87 million.

We own other fixed maturity securities which have exposure to cell towers, data centers and other collateral types that could be viewed as having real estate characteristics. We view these securities to have risks more akin to operating enterprises that do not share the same risks as the broader commercial real estate market. Additionally, we do not have significant real estate exposure through our limited partnership portfolio.

Duration

A primary objective in the management of the investment portfolio is to optimize return relative to the corresponding liabilities and respective liquidity needs. Our views on the current interest rate environment, tax regulations, asset class valuations, specific security issuer and broader industry segment conditions as well as domestic and global economic conditions, are some of the factors that enter into an investment decision. We also continually monitor exposure to issuers of securities held and broader industry sector exposures and may from time to time adjust such exposures based on our views of a specific issuer or industry sector.

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

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

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

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 2024, net cash provided by operating activities was $2,571 million as compared with $2,285 million for 2023. The increase in cash provided by operating activities was driven by an increase in premiums collected and higher earnings from fixed income securities, partially offset by an increase in net claim payments and higher operating expenses.

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.

For 2024, net cash used by investing activities was $1,317 million as compared with $1,843 million for 2023. Net cash used or provided 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 our common stock.

For 2024, net cash used by financing activities was $1,117 million as compared with $577 million for 2023. Financing activities for the periods presented include:

•In 2024, we issued $500 million of 5.125% notes due February 15, 2034 and repaid the $550 million outstanding aggregate principal balance of our 3.95% senior notes which came due May 15, 2024.

•In 2024, we paid dividends of $1,025 million and repurchased 450,000 shares of our common stock at an aggregate cost of $20 million.

•In 2023, we issued $500 million of 5.50% senior notes due June 15, 2033 and repaid the $243 million outstanding aggregate principal balance of our 7.25% debenture which came due November 15, 2023.

•In 2023, we paid dividends of $787 million and repurchased 550,000 shares of our common stock at an aggregate cost of $24 million.

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 $995 million and $1,055 million to CNAF during 2024 and 2023.

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

Common Stock Dividends

Cash dividends of $3.76 per share on our common stock, including a special cash dividend of $2.00 per share, were declared and paid in 2024. On February 7, 2025, our Board of Directors declared a quarterly cash dividend of $0.46 per share and a special cash dividend of $2.00 per share, payable March 13, 2025 to stockholders of record on February 24, 2025. 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 satisfy our 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 N 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.

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 conduct; 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 statements. We cannot control many of these risks and uncertainties. Material risks and uncertainties are addressed in Part I, Item IA Risk Factors and include, but are not limited to, the following:

OVERVIEW

The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, 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 the reserves are recorded as Future policy benefits reserves as discussed below. 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 benefits reserves for our long-term care policies are based on certain actuarial assumptions, including morbidity, persistency (inclusive of mortality), anticipated future premium rate increases, and expenses. 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 increase reserves. The reserves are discounted using upper-medium grade fixed income instrument yields as of each reporting date. In addition, we may not receive regulatory approval for the level of premium rate increases we request. 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 H 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

21

Table of Contents

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. 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.

RESERVES - ESTIMATES AND UNCERTAINTIES

The level of 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, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note E and F 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. 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 increases.

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 and the deferred retroactive reinsurance gains and the amount of remaining reinsurance limit.

Establishing Property & Casualty Reserve Estimates

In developing claim and claim adjustment expense 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 typically 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 economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, 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, 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 can be 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 the 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 reserve differs 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 US 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), errors and omissions (E&O), employment practices, fiduciary, fidelity, cyber 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 $500 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 $5.7 billion as of December 31, 2023.

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 $250 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 $250 million. Our net reserves for workers' compensation were approximately $3.6 billion as of December 31, 2023.

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 $250 million. If the estimated claim severity for general liability decreases by 3%, we estimate that our net reserves would decrease by approximately $150 million. Our net reserves for general liability were approximately $4.2 billion as of December 31, 2023.

Table of Contents

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, 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 may 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 future policy benefit reserves for our long-term care policies. Future policy benefit reserves for long-term care policies relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits. In developing the future policy benefit reserves, our actuaries perform a reserve review on an annual basis. During the annual review, historical policyholder morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expense experience is reviewed and compared to the current best estimate actuarial assumption set for potential revision. On a quarterly basis, our actuaries perform experience studies that monitor the appropriateness of best estimate actuarial assumptions against emerging experience to assess whether any updates to those assumptions are warranted. The determination of these reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policies. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk.

In addition, claim and claim adjustment expense reserves are maintained for our structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for our structured settlement obligations, our actuaries monitor mortality and expense 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 structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.

The actuarial assumptions related to future policy benefit reserves for long-term care policies that management believes are subject to the most variability are morbidity, persistency 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. 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.

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our liability for future policyholder benefits (LFPB) reserve assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group. The impact of each sensitivity is discrete and does not reflect the impact one factor may have on another or the mitigating impact from management actions, which may include additional future premium rate increases. 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. The estimated impacts to results of operations in the table below are after consideration of any net premium ratio impacts.

Morbidity:

5% increase in morbidity600

As part of the annual reserve review, statutory long-term care reserve adequacy is evaluated via premium deficiency testing, by comparing carried statutory reserves with our best estimate reserves, which incorporates best estimate discount rate and liability assumptions in its determination. Statutory margin is the excess of carried reserves over best estimate reserves. As of September 30, 2023, statutory long-term care margin increased to $1.3 billion, primarily driven by a more favorable interest rate environment resulting in a higher yielding investment portfolio.

CATASTROPHES AND RELATED REINSURANCE

Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, tornadoes, 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 United States of America (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 $236 million and $247 million for the years ended December 31, 2023 and 2022. Catastrophe losses for the years ended December 31, 2023 and 2022 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022.

We use various analyses and methods, including using one of the industry standard natural catastrophe models, to estimate hurricane and earthquake losses at various return periods and to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure through the purchase of catastrophe reinsurance and utilize various reinsurance programs to mitigate catastrophe losses, including excess-of-loss occurrence and aggregate treaties covering property and workers’ compensation, a property quota share treaty and the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA), as well as individual risk agreements that reinsure from losses from specific classes or lines of business. We conduct an ongoing review of our risk and catastrophe reinsurance 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, 2024.

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 and covered under a separate treaty. The treaty has a term of June 1, 2023 to June 1, 2024 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $235 million up to $1.1 billion for all losses other than earthquakes. Earthquakes are covered 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, 2024 to January 1, 2025 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 $775 million of coverage for the accumulation of covered losses related to terrorism events above our per occurrence retention of $25 million. Of the $775 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.

Terrorism Risk Insurance Program Reauthorization Act of 2019

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 2024. Under the current provisions of the program, in 2024, 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

29

Table of Contents

on eligible commercial property and casualty earned premiums for the preceding calendar year. Based on 2023 earned premiums, our estimated deductible under the program is $1.1 billion for 2024. 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.

See Note A to the Consolidated Financial Statements for additional information.

2023 Compared with 2022

Core income increased $448 million in 2023 as compared with 2022. Core income for our Property & Casualty Operations increased $265 million driven by higher net investment income and improved underwriting results. Core loss for our Life & Group segment decreased $173 million, while core loss for our Corporate & Other segment decreased $10 million.

Catastrophe losses were $236 million in 2023, primarily driven by severe weather related events. Catastrophe losses were $247 million in 2022, primarily related to Winter Storm Elliott and Hurricane Ian. Unfavorable net prior year loss reserve development of $48 million was recorded in 2023 as compared with favorable net prior year loss reserve development of $32 million in 2022 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.

2022 Compared with 2021

Core income decreased $252 million in 2022 as compared with 2021. Core income for our Property & Casualty Operations increased $56 million primarily due to improved underwriting results and higher net investment income from fixed income securities partially offset by lower investment income from limited partnerships and common stock. Core results for our Life & Group segment decreased $329 million, while core loss for our Corporate & Other segment decreased $21 million.

Catastrophe losses were $247 million in 2022 as compared with $397 million in 2021. Catastrophe losses for the years ended December 31, 2022 and 2021 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022 and Hurricane Ida and Winter Storms Uri and Viola for 2021.

Favorable net prior year loss reserve development of $32 million was recorded in 2022 as compared with unfavorable net prior year loss reserve development of $11 million in 2021 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 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, A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.

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. 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 and management believes some investors may find this measure useful to evaluate our primary operations. 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 P 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 underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophe losses and development-related items from the loss ratio. Development-related items represents net prior year loss reserve and premium development, and includes the effects of interest accretion and change in allowance for uncollectible reinsurance and deductible amounts. 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 underlying combined ratio is the sum of the underlying loss ratio, 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. Exposure represents the measure of risk used in the pricing of the insurance product. The change in exposure represents the change in premium dollars on policies that renew as a result of the change in risk of the policy. Retention represents the percentage of premium dollars renewed, excluding rate and exposure changes, in comparison to the expiring premium dollars from policies available to renew. 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. We use underwriting gain (loss), calculated using GAAP financial results, to monitor our insurance operations. Underwriting gain (loss) is pretax and is calculated as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and other insurance related expenses. Underlying underwriting gain (loss) represents underwriting results excluding catastrophe losses and development-related items.

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 and Note F to the Consolidated Financial Statements included under Item 8.

2023 Compared with 2022

Gross written premiums, excluding third-party captives, for Specialty decreased $14 million in 2023 as compared with 2022 driven by lower new business partially offset by strong retention. Net written premiums for Specialty increased $23 million in 2023 as compared with 2022. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $40 million in 2023 as compared with 2022 primarily due to higher net investment income partially offset by lower favorable net prior year loss reserve development, lower underlying underwriting results and lower income from non-insurance warranty business.

The combined ratio of 90.4% increased 1.8 point in 2023 as compared with 2022 primarily due to a 1.0 point increase in the expense ratio and a 0.8 point increase in the loss ratio. The increase in the expense ratio was driven by higher employee related and acquisition costs. The increase in the loss ratio was largely due to lower favorable net prior year loss reserve development. There were no catastrophe losses for 2023, as compared with $2 million, or 0.1 points of the loss ratio, for 2022.

Favorable net prior year loss reserve development of $14 million and $40 million was recorded in 2023 and 2022. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2023 Compared with 2022

Gross written premiums for Commercial increased $950 million in 2023 as compared with 2022 driven by higher new business and rate. Net written premiums for Commercial increased $687 million in 2023 as compared with 2022. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $186 million in 2023 as compared with 2022, driven by higher net investment income and improved current accident year underwriting results partially offset by lower favorable net prior year loss reserve development.

The combined ratio of 96.0% improved 1.3 points in 2023 as compared with 2022 due to a 0.8 point improvement in the expense ratio and a 0.5 improvement in the loss ratio. The improvement in the expense ratio was driven by higher net earned premiums partially offset by higher employee related costs. The improvement in the loss ratio was driven by lower catastrophe losses partially offset by lower favorable net prior year loss reserve development. Catastrophe losses were $207 million, or 4.5 points of the loss ratio, for 2023, as compared with $222 million, or 5.6 points of the loss ratio, for 2022.

Table of Contents

The combined ratio of 92.6% increased 0.8 points in 2023 as compared with 2022 due to a 1.9 point increase in the loss ratio partially offset by a 1.1 point improvement in the expense ratio. The increase in the loss ratio was driven by unfavorable net prior year loss reserve development of $13 million recorded for 2023 compared to favorable net prior year loss reserve development of $13 million recorded for 2022. Catastrophe losses were $29 million, or 2.5 points of the loss ratio, for 2023, as compared with $23 million, or 2.2 points of the loss ratio, for 2022. The improvement in the expense ratio was driven by higher net earned premiums and a favorable reinsurance acquisition related catch-up adjustment in the third quarter of 2023, partially offset by higher employee related costs.

Prior period amounts presented in the financial statements have been adjusted to reflect application of the new guidance. See Note A and Note F to the Consolidated Financial Statements for additional information.

2023 Compared with 2022

Core loss decreased $173 million in 2023 as compared with 2022 primarily due to higher net investment income and an unfavorable pretax impact of $181 million in the prior year as a result of the annual reserve reviews, partially offset by long-term care policy buyouts in 2023. Policy buyouts generally result in an unfavorable impact on core loss, as the cash payments are linked to higher statutory reserve levels. Excluding the impacts of long-term care policy buyouts, 2023 underwriting results are generally in line with reserving expectations.

Both years are inclusive of cash flow assumption updates as a result of the annual reserve review completed in the third quarter of each year. Cash flow assumption updates for 2023 resulted in an $8 million pretax increase in long-term care reserves. Adjusted to reflect the application of the LDTI accounting standard, the cash flow assumption updates for 2022 resulted in a $186 million pretax increase in long-term care reserves, primarily driven by the unfavorable impact of increased cost of care inflation, partially offset by favorable premium rate assumptions.

The annual structured settlement review resulted in a pretax reduction in claim reserves of $6 million and $5 million for 2023 and 2022.

2022 Compared with 2021

Results for both years have been adjusted to reflect the application of the LDTI accounting standard.

Core results decreased $329 million in 2022 as compared with 2021 primarily due to the unfavorable impact of the 2022 annual reserve reviews and lower net investment income.

Cash flow assumption updates, as a result of the annual reserve reviews, for 2022 resulted in an $186 million pretax increase in long-term care reserves compared to a $3 million pretax increase in 2021.

The annual structured settlement review resulted in a pretax reduction in claim reserves of $5 million for 2022 and a pretax increase to claim reserves of $2 million for 2021.

2023 Compared with 2022

Core loss decreased $10 million for 2023 as compared with 2022. The current year includes higher net investment income, a $19 million after-tax charge related to office consolidation, and a $56 million after-tax charge related to unfavorable prior period development for legacy mass tort claims compared with a $51 million after-tax charge for legacy mass tort claims in the prior year. The charge related to office consolidation is further discussed in Note M and net prior year loss reserve development is further discussed in Note E, to the Consolidated Financial Statements included under Item 8.

The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT resulted in an after-tax benefit of $6 million and $3 million in 2023 and 2022, both of which have no economic impact. The A&EP LPT is further discussed in Note E to the Consolidated Financial Statements included under Item 8.

Commercial Real Estate

Our investment portfolio has exposure to the commercial real estate sector primarily through our fixed maturity securities and mortgage loan portfolios. The performance of these assets is dependent on a number of factors, including the performance of the underlying collateral (which is influenced by cash flows from underlying property leases), changes in the fair value of collateral, refinancing risk, and the creditworthiness of tenants of credit tenant loan properties (where lease payments directly service the loan).

Within our fixed maturity securities portfolio, our exposure is primarily through our commercial mortgage-backed securities portfolio and our corporate and other bonds portfolio, which contains obligations of real estate investment trust (REIT) issuers. Commercial mortgage-backed securities include both single asset, single borrower collateral that is securitized independently and conduit collateral that is securitized in diversified pools.

The following tables present the estimated fair value and net unrealized gains (losses) of our commercial mortgage-backed securities by property type and by ratings distribution.

Mortgage loans are commercial in nature and are carried at unpaid principal balance, net of unamortized fees and an allowance for expected credit losses. 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). This assessment utilizes historical credit loss experience adjusted to reflect current conditions and reasonable and supportable forecasts. As of December 31, 2023 the allowance for expected credit losses on our mortgage portfolio was $35 million, or 3.3% of our amortized cost basis.

In addition to our mortgage loan portfolio, we invest in securitized credit tenant loans and ground lease financings that are classified as fixed maturity securities and are largely investment grade quality. As of December 31, 2023, these holdings had an estimated fair value of $479 million and net unrealized losses of $87 million.

We own other fixed maturity securities which have exposure to cell towers, data centers and other collateral types that could be viewed as having real estate characteristics. We view these securities to have risks more akin to operating enterprises that do not share the same risks as the broader commercial real estate market.

We do not hold any direct investments in commercial real estate. Additionally, we do not have significant exposure through our limited partnership portfolio to funds whose primary strategy is real estate focused.

Table of Contents

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.

Other investments27,9814.525,4454.7
Total$43,1186.5$39,9566.6

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 2023, net cash provided by operating activities was $2,285 million as compared with $2,502 million for 2022. The decrease in cash provided by operating activities was driven by higher net claim payments, which includes long-term care policy buyouts of $193 million, and higher operating expenses partially offset by an increase in premiums collected.

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

For 2023, net cash used by investing activities was $1,843 million as compared with $1,512 million for 2022. Net cash used or provided 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 our common stock.

For 2023, net cash used by financing activities was $577 million as compared with $1,032 million for 2022. Financing activities for the periods presented include:

•In 2023, we paid dividends of $787 million and repurchased 550,000 shares of our common stock at an aggregate cost of $24 million.

•In 2023, we issued $500 million of 5.50% senior notes due June 15, 2033 and repaid the $243 million outstanding aggregate principal balance of our 7.25% debenture which came due November 15, 2023.

•In 2022, we paid dividends of $982 million and repurchased 890,000 shares of our common stock at an aggregate cost of $39 million.

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, which was amended and restated during the fourth quarter of 2023, and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago (FHLBC). Further information on our Second Amended and Restated Credit Agreement is in Note I to the Consolidated Financial Statements included under Item 8.

CCC paid dividends of $1,055 million and $990 million to CNAF during 2023 and 2022.

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

Common Stock Dividends

Cash dividends of $2.88 per share on our common stock, including a special cash dividend of $1.20 per share, were declared and paid in 2023. On February 2, 2024, our Board of Directors declared a quarterly cash dividend of $0.44 per share and a special cash dividend of $2.00 per share, payable March 7, 2024 to stockholders of record on February 20, 2024. 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 satisfy our 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 N to the Consolidated Financial Statements included under Item 8.

Commitments, Contingencies and Guarantees

We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

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, see Note A to the Consolidated Financial Statements included under Item 8.

RECENT TAX LEGISLATION

Corporate Alternative Minimum Tax

The Inflation Reduction Act was enacted on August 16, 2022, and includes, among other provisions, a corporate alternative minimum tax (CAMT) of 15%, effective January 1, 2023, imposed on the adjusted financial statement income (AFSI) of an applicable corporation whose average annual AFSI over three prior years exceeds $1 billion. Based on interpretations of the CAMT and current guidance, we believe that the CAMT has no impact on our financial results for the year ended December 31, 2023. Along with Loews, we will continue to monitor as additional technical guidance from the U.S. Department of Treasury, including forthcoming proposed regulations, becomes available.

Pillar Two

The Organization for Economic Co-operation and Development/G20 Inclusive Framework on Base Erosion and Profit Shifting has introduced rules to establish a global minimum corporate tax rate of 15%, commonly referred to as the Pillar Two rules. Numerous foreign countries have enacted legislation to implement the Pillar Two rules, effective beginning in 2024, or are expected to enact similar legislation. We are currently evaluating the potential impacts that Pillar Two may have on future periods and will continue to monitor the implementation of the Pillar Two rules in the jurisdictions in which we operate.

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 conduct; 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 statements. We cannot control many of these risks and uncertainties. Material risks and uncertainties are addressed in Part I, Item IA Risk Factors and 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 transactions in which, subject to certain limitations, we ceded our legacy A&EP and EWC liabilities, respectively, will not fully perform their respective obligations to CNA, the uncertainty in estimating loss reserves for A&EP and EWC liabilities and the possible continued exposure of CNA to liabilities for A&EP and EWC claims that are not covered under the terms of the respective transactions; and

•the performance of reinsurance companies under reinsurance contracts with us.

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

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

Regulatory, Legal and Operational Factors

•regulatory and legal initiatives and compliance with governmental regulations and other legal requirements, which are increasing in complexity and number, change frequently, sometimes conflict, and could expose us to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution in one or more jurisdictions, including regulations related to cybersecurity protocols (which continue to evolve in breadth, sophistication and maturity in response to an ever-evolving threat landscape), 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;

OVERVIEW

The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, 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 require increases 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. Further information on our income taxes is in Note D to the Consolidated Financial Statements included under Item 8.

RESERVES - ESTIMATES AND UNCERTAINTIES

The level of 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, 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. 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 and the deferred retroactive reinsurance gains 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 typically 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 economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, 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, 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 can be 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 the 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 reserve differs 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 US 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), errors and omissions (E&O), employment practices, fiduciary, fidelity, cyber 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 $500 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 $5.3 billion as of December 31, 2022.

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 $300 million. Our net reserves for workers' compensation were approximately $3.7 billion as of December 31, 2022.

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 $3.6 billion as of December 31, 2022.

Table of Contents

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, 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

27

Table of Contents

existing 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.

Information regarding ASU 2018-12, which, beginning in 2023, will require changes in the measurement and disclosure of long-duration contracts, including our long term care business, is provided in the Accounting Standards Update section of this MD&A and in Note A to the Consolidated Financial Statements included under Item 8.

The September 30, 2022 GPV indicated that our recorded reserves included a margin of approximately $125 million. A summary of the changes in the estimated reserve margin is presented in the table below:

Long Term Care Active Life Reserve - Change in estimated reserve margin (In millions)
September 30, 2021 Estimated Margin$72
Changes in underlying economic assumptions(1)(130)
Changes in underlying morbidity assumptions(30)
Changes in underlying persistency assumptions40
Changes in underlying premium rate action assumptions190
Changes in underlying expense and other assumptions(17)
September 30, 2022 Estimated Margin$125

(1) Economic assumptions include the impact of interest rates and cost of care inflation.

The increase in the margin in 2022 was primarily driven by changes in discount rate assumptions due to higher near-term expected reinvestment rates and higher than previously estimated rate increases on active rate increase programs. These favorable drivers were partially offset by changes in cost of care inflation assumptions.

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

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our future policy benefit reserve assumptions. The annual GPV process involves updating all assumptions to management's then current best estimate, and historically all significant assumptions have been revised each year. In the table below, we have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group. The impact of each sensitivity is discrete and does not reflect the impact one factor may have on another or the mitigating impact from management actions, which may include additional future premium rate increases. Although such hypothetical revisions are not currently required or anticipated, we believe they could occur based on past variances in experience and our expectations of the ranges of future experience that could reasonably occur. Any required increase in the recorded reserves resulting from a hypothetical revision in the table below would first reduce the margin in our carried reserves before it would affect results from operations. Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized below. The estimated impacts to results of operations in the table below are after consideration of the existing margin.

CATASTROPHES AND RELATED REINSURANCE

Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, tornadoes, 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 $247 million and $397 million for the years ended December 31, 2022 and 2021. Catastrophe losses for the years ended December 31, 2022 and 2021 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022 and Hurricane Ida and Winter Storms Uri and Viola for 2021.

We use various analyses and methods, including using one of the industry standard natural catastrophe models to estimate hurricane and earthquake losses at various return periods, to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure 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 reinsurance coverages and from time to time make changes as we deem appropriate.

In 2021, we added a quota share treaty to our property reinsurance program, which covers policies written during the treaty term and in-force as of June 1, 2021. As a result of the coverage of in-force policies, net written premiums were reduced by $122 million during the second quarter of 2021 for the one-time catch-up under the treaty of unearned premium on policies previously written as of the treaty inception. The treaty was renewed for a term of June 1, 2022 to June 1, 2023.

The following discussion summarizes our most significant catastrophe reinsurance coverage at January 1, 2023.

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 and covered under a separate treaty. The treaty has a term of June 1, 2022 to June 1, 2023 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $190 million up to $900 million for all losses other than earthquakes. Earthquakes are covered up to $1.0 billion. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological or chemical attack. All layers of the treaty provide for one full reinstatement.

Group Workers' Compensation Treaty

We also purchased corporate Workers' Compensation catastrophe excess-of-loss treaty reinsurance for the period January 1, 2023 to January 1, 2024 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 $600 million of coverage for the accumulation of covered losses related to terrorism events above our retention of $25 million. Of this $600 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.

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 2023. Under the current provisions of the program, in 2023, 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 2022 earned premiums, our estimated deductible under the program is $1 billion for 2023. 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.

2022 Compared with 2021

Core income decreased $58 million in 2022 as compared with 2021. Core income for our Property & Casualty Operations increased $56 million primarily due to improved underwriting results and higher net investment income from fixed income securities partially offset by lower investment income from limited partnership and common stock results. Core results for our Life & Group segment decreased $135 million, while core loss for our Corporate & Other segment improved $21 million.

Catastrophe losses were $247 million in 2022 as compared with $397 million in 2021. Catastrophe losses for the years ended December 31, 2022 and 2021 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022 and Hurricane Ida and Winter Storms Uri and Viola for 2021.

Favorable net prior year loss reserve development of $32 million was recorded in 2022 as compared with unfavorable net prior year loss reserve development of $11 million in 2021 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 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, A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.

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 and management believes some investors may find this measure useful to evaluate our primary operations. 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 underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophes losses and net prior year loss reserve and premium development 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 underlying combined ratio is the sum of the underlying loss ratio, 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, excluding rate and exposure changes, 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. We use underwriting gain (loss) to monitor our insurance operations. Underwriting gain (loss) is pretax and is calculated as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and other insurance related expenses.

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

2022 Compared with 2021

Gross written premiums, excluding third-party captives, for Specialty increased $142 million in 2022 as compared with 2021 driven by retention and rate. Net written premiums for Specialty increased $81 million in 2022 as compared with 2021. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income decreased $36 million in 2022 as compared with 2021 primarily due to lower net investment income driven by limited partnership and common stock results partially offset by improved current accident year underwriting results.

The combined ratio of 88.6% improved 0.1 point in 2022 as compared with 2021 primarily due to a 0.7 point improvement in the loss ratio largely offset by a 0.5 point increase in the expense ratio. The improvement in the loss ratio was largely due to improved current accident year underwriting results. Catastrophe losses were $2 million, or 0.1 points of the loss ratio, for 2022, as compared with $12 million, or 0.4 points of the loss ratio, for 2021. The increase in the expense ratio was primarily due to an increase in underwriting expenses driven by investments in technology and talent.

Favorable net prior year loss reserve development of $40 million and $45 million was recorded in 2022 and 2021. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2022 Compared with 2021

Gross written premiums for Commercial increased $725 million in 2022 as compared with 2021 driven by higher new business and retention. Net written premiums for Commercial increased $598 million in 2022 as compared with 2021. The prior period included a one-time written premium catch-up resulting from the addition of a quota share treaty to our property reinsurance program. Excluding the impact of the prior period written premium catch-up, net written premiums increased $486 million in 2022 as compared with 2021. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $72 million in 2022 as compared with 2021, driven by lower catastrophe losses and improved non-catastrophe underwriting results partially offset by lower net investment income driven by limited partnerships and common stock results.

The combined ratio of 97.3% improved 5.8 points in 2022 as compared with 2021 primarily due to a 5.1 improvement in the loss ratio and a 0.7 point improvement in the expense ratio. The improvement in the loss ratio was driven by lower catastrophe losses and higher favorable net prior year loss reserve development. Catastrophe losses were $222 million, or 5.6 points of the loss ratio, for 2022, as compared with $358 million,

or 10.0 points of the loss ratio, for 2021. The combined ratio excluding catastrophes and development improved 0.2 points in 2022 as compared with 2021. The improvement in the expense ratio of 0.7 points was driven by higher net earned premiums and lower acquisition costs partially offset by an increase in underwriting expenses. The loss ratio excluding catastrophes and development increased 0.5 points primarily driven by a shift in mix of business associated with the property quota share treaty purchased during June of 2021. Our property coverages, which have a lower underlying loss ratio than most other commercial coverages, now represent a smaller proportion of net earned premiums.

Favorable net prior year loss reserve development of $43 million and $6 million was recorded in 2022 and 2021. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

2022 Compared with 2021

Core loss improved $21 million for 2022 as compared with 2021 driven by favorability related to the A&EP Loss Portfolio Transfer (LPT) and the prior period recognition of a $12 million after-tax loss resulting from the legacy EWC LPT. These results were partially offset by an increase in expenses as result of continued investments in technology infrastructure and security.

The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT resulted in an after-tax benefit of $3 million in 2022 compared to an after-tax charge of $25 million in 2021, both of which have no economic impact. The A&EP LPT and EWC LPT are further discussed in Note E to the Condensed Consolidated Financial Statements included under Item 8.

PENSION PLAN IMPACT ON 2023 RESULTS

We anticipate a net pension cost of approximately $12 million in 2023 as compared with a benefit of $55 million in 2022. The change is primarily due to higher interest cost on projected benefit obligations as a result of an increase in discount rates year over year, as well as a lower expected return on plan assets as a result of a lower plan asset base given actual asset returns in 2022. A portion of this additional cost will result in an unfavorable impact on our expense ratio in 2023.

Our legacy pension plan is further discussed in Note I to the Condensed Financial Statements included under Item 8.

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.

Other investments25,4454.728,9154.9
Total$39,9566.6$47,3736.6

The effective duration of Investments supporting Life & Group liabilities at December 31, 2022 lengthened as compared with December 31, 2021, reflecting strategic repositioning to capitalize on higher rates and reduce reinvestment risk.

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 2022, net cash provided by operating activities was $2,502 million as compared with $1,997 million for 2021. The increase in cash provided by operating activities was driven by the prior year payment of the EWC LPT premium. The EWC LPT is further discussed in Note E to the Consolidated Financial Statements included under Part II, Item 8.

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.

For 2022, net cash used by investing activities was $1,512 million as compared with $1,228 million for 2021. Net cash used or provided 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 our common stock.

For 2022, net cash used by financing activities was $1,032 million as compared with $648 million for 2021. Financing activities for the periods presented include:

•In 2022, we paid dividends of $982 million and repurchased 890,000 shares of our common stock at an aggregate cost of $39 million.

•In 2021, we paid dividends of $621 million and repurchased 377,615 shares of our common stock at an aggregate cost of $18 million.

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 $990 million and $880 million to CNAF during 2022 and 2021.

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

Common Stock Dividends

Cash dividends of $3.60 per share on our common stock, including a special cash dividend of $2.00 per share, were declared and paid in 2022. On February 3, 2023, our Board of Directors declared a quarterly cash dividend of $0.42 per share and a special cash dividend of $1.20 per share, payable March 9, 2023 to stockholders of record on February 21, 2023. 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.

Commitments, Contingencies and Guarantees

We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

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

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. For the Company, this includes the long term care business. The Company will adopt the new guidance effective January 1, 2023, using the modified retrospective method applied as of the transition date of January 1, 2021.

The most significant impact will be the effect of updating the discount rate assumption quarterly to reflect an upper-medium grade fixed-income instrument yield, rather than CNA’s expected investment portfolio yield. This will be partially offset by the de-recognition of Shadow Adjustments associated with long-duration contracts. The Company expects the net impact of these changes will be a decrease of approximately $2.3 billion in Accumulated other comprehensive income (AOCI) as of the transition date of January 1, 2021. To illustrate the sensitivity of this adjustment, had the Company used interest rates in effect as of December 31, 2022 in its calculation, the transition impact to AOCI would have been a decrease of approximately $250 million.

The requirement to review, and update if there is a change, cash flow assumptions at least annually is expected to change the pattern of earnings being recognized. Under current accounting guidance, the Company’s third quarter 2022 gross premium valuation assessment indicated a pretax reserve margin of $125 million, with no unlocking event. However under the new guidance, the effect of changes in cash flow assumptions from the Company’s assessment would be recorded in the Company’s results of operations (except for discount rate changes which would be recorded quarterly through AOCI).

For a discussion of Accounting Standards, 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 conduct; 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 statements. These risks and uncertainties are addressed in Part I, Item IA Risk Factors and include, but are not limited to, the following:

Company-Specific Factors

OVERVIEW

The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, 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 require increases 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

Table of Contents

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 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, 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. 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 and the deferred retroactive reinsurance gains 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 typically 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

Table of Contents

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 economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, 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, 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 can be 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 the 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 reserve differs 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 US 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 $450 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 $5.0 billion as of December 31, 2021.

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, 2021.

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 $3.2 billion as of December 31, 2021.

Table of Contents

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, 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

27

Table of Contents

existing 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.

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

Long Term Care Active Life Reserve - Change in estimated reserve margin (In millions)
September 30, 2020 Estimated Margin$
Changes in underlying discount rate assumptions(1)65
Changes in underlying morbidity assumptions205
Changes in underlying persistency assumptions(233)
Changes in underlying premium rate action assumptions27
Changes in underlying expense and other assumptions8
September 30, 2021 Estimated Margin$72

(1) Including cost of care inflation assumption.

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

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

The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our active life reserve assumptions. The annual GPV process involves updating all assumptions to management's then current best estimate, and historically all significant assumptions have been revised each year. In the table below, we have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group and would occur absent any changes, mitigating or otherwise, in the other assumptions. Although such hypothetical revisions are not currently required or anticipated, we believe they could occur based on past variances in experience and our expectations of the ranges of future experience that could reasonably occur. Any required increase in the recorded reserves resulting from a hypothetical revision in the table below would first reduce the margin in our carried reserves before it would affect results from operations. Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized below. The estimated impacts to results of operations in the table below are after consideration of the existing margin.

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 $397 million and $550 million for the years ended December 31, 2021 and 2020. Net catastrophe losses for the year ended December 31, 2021 were driven by severe weather related events, primarily Hurricane Ida and Winter Storms Uri and Viola. 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.

We use various analyses and methods, including using one of the industry standard natural catastrophe models to estimate hurricane and earthquake losses at various return periods, to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure 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 reinsurance coverages and from time to time make changes as we deem appropriate.

During the second quarter of 2021, we added a quota share treaty to our property reinsurance program, which covers policies written during the treaty term and in-force as of June 1, 2021. As a result of the coverage of in-force policies, net written premiums were reduced by $122 million during the second quarter for the one-time catch-up under the treaty of unearned premium on policies previously written as of the June 1, 2021 treaty inception. This ceded premium will earn in future quarters consistent with the underlying gross policies.

The following discussion summarizes our most significant catastrophe reinsurance coverage at January 1, 2022.

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 and covered under a separate treaty. The treaty has a term of June 1, 2021 to June 1, 2022 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $190 million up to $900 million for all losses other than earthquakes. Earthquakes are covered up to $1.0 billion. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological or chemical attack. All layers of the treaty provide for one full reinstatement.

Group Workers' Compensation Treaty

We also purchased corporate Workers' Compensation catastrophe excess-of-loss treaty reinsurance for the period January 1, 2022 to January 1, 2023 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.

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 2022. Under the current provisions of the program, in 2022, 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 2021 earned premiums, our estimated deductible under the program is $915 million for 2022. 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.

2021 Compared with 2020

Core income increased $371 million in 2021 as compared with 2020. Core income for our Property & Casualty Operations increased $344 million primarily due to improved current accident year underwriting results and higher net investment income driven by limited partnership and common stock returns. Core income for our Life & Group segment improved $117 million. Core loss for our Corporate & Other segment increased $90 million.

Net catastrophe losses were $397 million in 2021 as compared with $550 million in 2020. Catastrophe losses for the year ended December 31, 2021 were driven by severe weather related events, primarily Hurricane Ida and Winter Storms Uri and Viola. 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.

Unfavorable net prior year loss reserve development of $11 million was recorded in 2021 as compared with favorable net prior year loss reserve development of $20 million in 2020 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 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, A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.

Effective January 1, 2021, we changed the segment presentation of a legacy portfolio of excess workers compensation policies and certain legacy mass tort reserves. These businesses were previously reported in the Commercial business segment and are now reported as part of the Corporate & Other business segment. Prior period information has been conformed to the new segment presentation. See Note O to the Consolidated Financial Statements included under Item 8 for more information on the changes to our business segments.

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

32

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.

2021 Compared with 2020

Gross written premiums, excluding third-party captives, for Specialty increased $376 million in 2021 as compared with 2020 driven by rate and higher new business. Net written premiums for Specialty increased $185 million in 2021 as compared with 2020. The increase in net earned premiums was consistent with the trend in net written premiums.

Core income increased $169 million in 2021 as compared with 2020 primarily due to lower net catastrophe losses, improved non-catastrophe current accident year underwriting results and higher net investment income driven by limited partnership and common stock returns.

The combined ratio of 88.7% improved 4.8 points in 2021 as compared with 2020 due to a 4.0 point improvement in the loss ratio and a 0.8 point improvement in the expense ratio. The improvement in the loss ratio was primarily due to lower net catastrophe losses. Net catastrophe losses were $12 million, or 0.4 points of the loss ratio, for 2021, as compared with $125 million, or 4.3 points of the loss ratio, for 2020. The improvement in the expense ratio was driven by higher net earned premiums.

Favorable net prior year loss reserve development of $45 million and $61 million was recorded in 2021 and 2020. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

Gross written premiums for Commercial increased $359 million in 2021 as compared with 2020 driven by rate and higher new business. Net written premiums for Commercial increased $30 million in 2021 as compared with 2020. Net written premiums for 2021 were unfavorably impacted by the June 1, 2021 written premium catch-up resulting from the addition of the quota share treaty to our property reinsurance program. Excluding the impact of the June 1, 2021 written premium catch-up, net written premiums increased $142 million for 2021 as compared with 2020. Net earned premiums for Commercial increased $229 million in 2021 as compared with 2020. The increase in net earned premiums was partially impacted by a reduction in estimated audit premiums related to COVID-19 in 2020.

Table of Contents

Core income increased $127 million in 2021 as compared with 2020, primarily due to higher net investment income driven by limited partnership and common stock returns and improved current accident year underwriting results.

The combined ratio of 103.1% improved 2.0 points in 2021 as compared with 2020 primarily due to a 1.9 point improvement in the expense ratio. The improvement in the expense ratio was primarily due to higher net earned premiums and lower acquisition costs. Net catastrophe losses were $358 million, or 10.0 points of the loss ratio, for 2021, as compared with $358 million, or 10.7 points of the loss ratio, for 2020.

Favorable net prior year loss reserve development of $6 million and $7 million was recorded in 2021 and 2020. 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.

Core income decreased $213 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 105.1% increased 5.6 points in 2020 as compared with 2019 due to an increase in the loss ratio primarily driven by higher net catastrophe losses. 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.

Favorable net prior year loss reserve development of $7 million and $40 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.

Core loss increased $90 million for 2021 as compared with 2020 driven by lower net investment income, unfavorability related to the A&EP Loss Portfolio Transfer (LPT), expenses related to the March 2021 cybersecurity attack, the recognition of a $12 million after-tax loss resulting from the legacy EWC LPT and higher unfavorable net prior year loss reserve development on legacy mass tort exposures.

The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT in both periods resulted in after-tax charges of $25 million and $5 million in 2021 and 2020, respectively, which have no economic impact.

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.

Other investments28,9154.928,8394.5
Total$47,3736.6$47,3576.3

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

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 2021, net cash provided by operating activities was $1,997 million as compared with $1,775 million for 2020. The increase in cash provided by operating activities was driven by an increase in net premiums collected and lower net claim payments, which were impacted by a slowdown in court dockets. These items were partially offset by the payment of the EWC LPT premium. The EWC LPT is further discussed in Note E to the Consolidated Financial Statements included under Part II, Item 8.

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 $1,228 million for 2021, as compared with $705 million for 2020. Net cash used or provided 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 $648 million and $902 million for 2021 and 2020. Financing activities for the periods presented include:

•In 2021, we paid dividends of $621 million and repurchased 377,615 shares of our common stock at an aggregate cost of $18 million.

•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.

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 $880 million and $975 million to CNAF during 2021 and 2020.

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.

Common Stock Dividends

Cash dividends of $2.27 per share on our common stock, including a special cash dividend of $0.75 per share, were declared and paid in 2021. On February 4, 2022, our Board of Directors declared a quarterly cash dividend of $0.40 per share and a special cash dividend of $2.00 per share, payable March 10, 2022 to stockholders of record on February 22, 2022. 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.

Commitments, Contingencies and Guarantees

We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

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, 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 transactions in which, subject to certain limitations, we ceded our legacy A&EP and EWC liabilities, respectively, will not fully perform their respective obligations to CNA, the uncertainty in estimating loss reserves for A&EP and EWC liabilities and the possible continued exposure of CNA to liabilities for A&EP and EWC claims that are not covered under the terms of the respective transactions;

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

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

Industry and General Market Factors

•the COVID-19 pandemic and measures to mitigate the spread of the virus may continue to result in increased claims and related litigation risk across our enterprise;

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

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

•general economic and business conditions, including recessionary conditions that may decrease the size and number of our insurance customers and create losses to our lines of business and inflationary pressures on medical care costs, construction costs and other economic sectors, as well as social inflation, that increase the severity of claims;

•conditions in the capital and credit markets, including uncertainty and instability in these markets, as well as the overall economy, and their impact on the returns, types, liquidity and valuation of our investments;

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

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