Notes to Condensed Consolidated Financial Statements
Note A. General
Basis of Presentation
The Condensed Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned 91.7% of the outstanding common stock of CNAF as of September 30, 2023.
The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, including certain financial statement notes, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in CNAF's Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) for the year ended December 31, 2022, including the summary of significant accounting policies in Note A. The preparation of Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
The interim financial data as of September 30, 2023 and for the three and nine months ended September 30, 2023 and 2022 is unaudited. However, in the opinion of management, the interim data includes all adjustments, including normal recurring adjustments, necessary for a fair statement of the Company's results for the interim periods in accordance with GAAP. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2022 Consolidated Balance Sheet included in this Quarterly Report on Form 10-Q was derived from audited financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC, adjusted for the application of ASU 2018-12, Financial Services-Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (ASU 2018-12).
Recently Adopted Accounting Standards Updates (ASU)
ASU 2018-12: In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-12, which requires changes to the measurement and disclosure of long-duration contracts. Entities are required to review, and update if there is a change, cash flow assumptions (including morbidity and persistency) used to measure the liability for future policyholder benefits (LFPB) at least annually. The LFPB must also be updated for actual experience at least annually. The LFPB is reflected as Insurance reserves: Future policy benefits on the Condensed Consolidated Balance Sheet. The discount rate assumption used to measure the LFPB must be updated quarterly using an upper-medium grade (low credit risk) fixed-income instrument yield, commonly interpreted as a single-A rate. The effect of changes in cash flow assumptions and actual variances from expected experience are recorded in the Company's results of operations within Insurance claims and policyholders’ benefits. The effect of changes in discount rate assumptions are recorded in Other comprehensive income (loss). In contrast, under legacy accounting guidance, cash flow and discount rate assumptions were locked-in unless a premium deficiency emerged. The discount rate assumption under legacy accounting guidance was determined using the Company’s internal investment portfolio yield, which was generally higher than a single-A yield.
The new guidance eliminates the need to hold shadow reserves associated with the Company’s long term care reserves. Under legacy accounting guidance, to the extent that unrealized gains on fixed maturity securities supporting long term care reserves would have resulted in a premium deficiency if realized, a related increase to Insurance reserves was recorded, net of tax, as a reduction of net unrealized gains (losses), through Other comprehensive income (loss) (shadow reserves).

Table of Contents
The unit of account is the level at which reserves are measured. Under the new guidance, the unit of account used to measure the LFPB is the cohort. Cohorts are comprised of insurance contracts issued no more than one year apart, and must be further disaggregated according to policy benefit and insurance risk characteristics. Under legacy accounting guidance, the LFPB was generally measured at the individual policy level.
Under the new guidance, the Net Premium Ratio (NPR) is capped at 100%. To the extent that NPR would otherwise exceed 100%, the LFPB is increased and a loss is recognized immediately in the Company’s results of operations. The NPR cap is applied at the cohort level each quarter when NPR is updated. In contrast, under legacy accounting guidance, premium deficiency testing was performed annually at the product level. See Note F to the Condensed Consolidated Financial Statements for further explanation of the NPR and LFPB calculations.
The Company adopted the new guidance effective January 1, 2023, using the modified retrospective method applied as of the transition date of January 1, 2021. The Company's run-off long term care business is in scope of the new guidance. All prior periods presented in the financial statements have been adjusted to reflect application of the new guidance. The Company’s original locked in discount rate, utilized for purposes of calculating the NPR under the new guidance, was based on the discount rate assumption used to calculate the LFPB immediately prior to the transition date. While the requirements of the new guidance represent a material change from legacy accounting, the new guidance does not impact capital and surplus under statutory accounting practices, cash flows or the underlying economics of the business.
In December 2022, the FASB issued ASU 2022-05, Financial Services-Insurance (Topic 944): Transition for Sold Contracts (ASU 2022-05). This guidance permits companies to make an election to exclude from the scope of ASU 2018-12 any insurance contracts that have been de-recognized prior to the effective date of ASU 2018-12, assuming that the company has no significant continuing involvement with the de-recognized contracts. In the fourth quarter of 2022, the Company novated its block of legacy annuity business, which was fully-ceded prior to novation. The Company has elected the ASU 2022-05 transition relief, and has excluded the novated legacy annuity business from the scope of ASU 2018-12.
Explanation of ASU 2018-12 Transition Impacts:
The following table presents a roll-forward of the pre-transition LFPB balance as of January 1, 2021:

(In millions) |
Balance as of December 31, 2020, as previously reported | $ | 13,318 |
Reclassification of reserves for policyholders currently receiving benefits to Future policy benefits (1) | 2,844 |
De-recognition of shadow reserves | (3,293) |
Re-measurement using an upper-medium grade fixed income instrument yield discount rate | 6,255 |
Other adjustments | 8 |
Balance as of January 1, 2021, as adjusted | $ | 19,132 |

(1) In conjunction with the adoption of ASU 2018-12, at January 1, 2023, the Company reclassified the long term care reserves for policyholders currently receiving benefits from Claim and claim adjustment expenses to Future policy benefits. This change was applied retrospectively as of January 1, 2021.
Shadow reserves associated with the Company’s long term care business were de-recognized as of the transition date in Accumulated other comprehensive income (AOCI). The effect of re-measuring the LFPB at the single-A discount rate as of the transition date was similarly recorded in AOCI. The Company did not have any cohorts for which the NPR exceeded 100% at the transition date.
The Company’s practice under legacy accounting guidance was to calculate and record premium deficiency reserves at the policy level. Accordingly, an allocation methodology was not required to assign historical premium deficiency reserves to cohorts upon transition to ASU 2018-12.

Note B. Earnings (Loss) Per Share Data
Earnings (loss) per share is based on weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the impact of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
The following table presents the income and share data used in the basic and diluted earnings per share computations.

(1) As of January 1, 2023, the Company adopted ASU 2018-12 using the modified retrospective method applied as of the transition date of January 1, 2021. Prior period amounts have been adjusted to reflect application of the new guidance.
Excluded from the calculation of diluted earnings (loss) per share is the impact of potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans that would have been antidilutive during the respective periods.
The Company repurchased 550,000 and 890,000 shares of CNAF common stock at an aggregate cost of $24 million and $39 million during the nine months ended September 30, 2023 and 2022.

Net investment gains (losses) for the three months ended September 30, 2022 in the table above included a $35 million net loss related to the novation of a coinsurance agreement on the Company’s legacy annuity business, which was transacted on a funds withheld basis and gave rise to an embedded derivative. The net loss of $35 million was comprised of a $59 million loss on the fixed maturity securities supporting the funds withheld liability to recognize unrealized losses which had been included in AOCI since the inception of the coinsurance agreement, partially offset by a $24 million gain on the associated embedded derivative. Taken together, this net loss was the final recognition of changes in the valuation of the funds held assets and offsets previously recognized net investment gains on the associated embedded derivative. The coinsurance agreement was novated in the fourth quarter of 2022.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the September 30, 2023 securities in a gross unrealized loss position tables above are not indicative of the ultimate collectability of the current amortized cost of the securities, but rather are primarily attributable to changes in risk-free interest rates. In reaching this determination, the Company considered the continued volatility in risk-free rates and credit spreads as well as the fact that its unrealized losses are concentrated in investment grade issuers. Additionally, the Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional impairment losses to be recorded as of September 30, 2023.

Note D. Fair Value
Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable.
Level 1 - Quoted prices for identical instruments in active markets.
Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.
Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are not observable.
Prices may fall within Level 1, 2 or 3 depending upon the methodology and inputs used to estimate fair value for each specific security. In general, the Company seeks to price securities using third-party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using a methodology and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company.
The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures may include i) the review of pricing service methodologies or broker pricing qualifications, ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, iii) exception reporting, where period-over-period changes in price are reviewed and challenged with the pricing service or broker based on exception criteria, and iv) deep dives, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities.

Table of Contents
Valuation Methodologies and Inputs
The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified.
Fixed Maturity Securities
Level 1 securities include highly liquid government securities and exchange traded bonds, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using a methodology based on information generated by market transactions involving identical or comparable assets, a discounted cash flow methodology, or a combination of both when necessary. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are primarily assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with some inputs that are not market observable.
Equity Securities
Level 1 equity securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily valued using pricing for similar securities, recently executed transactions and other pricing models utilizing market observable inputs. Level 3 securities are primarily priced using broker/dealer quotes and internal models with some inputs that are not market observable.
Short Term and Other Invested Assets
Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds and treasury bills. Level 2 primarily includes non-U.S. government securities for which all inputs are market observable. Fixed maturity securities purchased within one year of maturity are classified consistent with fixed maturity securities discussed above. Short term investments as presented in the tables above differ from the amounts presented on the Condensed Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.
As of September 30, 2023 and December 31, 2022, there were $63 million and $72 million of overseas deposits within Other invested assets, which can be redeemed at net asset value in 90 days or less. Overseas deposits are excluded from the fair value hierarchy because their fair value is recorded using the net asset value per share (or equivalent) practical expedient.
Other Liabilities
Level 2 securities include currency forward contracts valued using observable market forward rates.

Significant Unobservable Inputs
The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurements of Level 3 assets. Valuations for assets and liabilities not presented in the tables below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company. The weighted average rate is calculated based on fair value.

September 30, 2023 | Estimated Fair Value (In millions) |  | Valuation Technique(s) |  | Unobservable Input(s) |  | Range (Weighted Average)
Fixed maturity securities | $ | 1,359 |  |  | Discounted cash flow |  | Credit spread |  | 1% - 7% (2%)

December 31, 2022 | Estimated Fair Value (In millions) |  | Valuation Technique(s) |  | Unobservable Input(s) |  | Range (Weighted Average)
Fixed maturity securities | $ | 1,177 |  |  | Discounted cash flow |  | Credit spread |  | 1% - 8% (2%)

For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement.
Financial Assets and Liabilities Not Measured at Fair Value

Note E. Claim and Claim Adjustment Expense Reserves
Claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to historical patterns such as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and economic conditions, economic, medical and social inflation, and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.
Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers' compensation, general liability and professional liability claims. Claim and claim adjustment expense reserves are also maintained for the Company's structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for structured settlement obligations, the Company's actuaries review mortality experience on an annual basis. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the Company's ultimate cost for insurance losses will not exceed current estimates.
Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in our results of operations and/or equity. The Company reported catastrophe losses, net of reinsurance, of $94 million and $214 million for the three and nine months ended September 30, 2023, primarily related to severe weather related events. The Company reported catastrophe losses, net of reinsurance, of $114 million and $171 million for the three and nine months ended September 30, 2022 primarily related to severe weather events, including $87 million for Hurricane Ian.

Asbestos & Environmental Pollution (A&EP) Reserves
In 2010, Continental Casualty Company (CCC) together with several of the Company’s insurance subsidiaries completed a transaction with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which substantially all of the Company’s legacy A&EP liabilities were ceded to NICO through a Loss Portfolio Transfer (LPT). At the effective date of the transaction, the Company ceded approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $4 billion. The $1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third-party reinsurance contracts. The NICO LPT aggregate reinsurance limit also covers credit risk on the existing third-party reinsurance related to these liabilities. The Company paid NICO a reinsurance premium of $2 billion and transferred to NICO billed third-party reinsurance receivables related to A&EP claims with a net book value of $215 million, resulting in total consideration of $2.2 billion.
In years subsequent to the effective date of the LPT, the Company recognized adverse prior year development on its A&EP reserves resulting in additional amounts ceded under the LPT. As a result, the cumulative amounts ceded under the LPT have exceeded the $2.2 billion consideration paid, resulting in the NICO LPT moving into a gain position, requiring retroactive reinsurance accounting. Under retroactive reinsurance accounting, this gain is deferred and only recognized in earnings in proportion to actual paid recoveries under the LPT. Over the life of the contract, there is no economic impact as long as any additional losses incurred are within the limit of the LPT. In a period in which the Company recognizes a change in the estimate of A&EP reserves that increases or decreases the amounts ceded under the LPT, the proportion of actual paid recoveries to total ceded losses is affected and the change in the deferred gain is recognized in earnings as if the revised estimate of ceded losses was available at the effective date of the LPT. The effect of the deferred retroactive reinsurance benefit is recorded in Insurance claims and policyholders' benefits on the Condensed Consolidated Statements of Operations.
The impact of the LPT on the Condensed Consolidated Statements of Operations was the recognition of a retroactive reinsurance benefit of $15 million and $17 million for the three months ended September 30, 2023 and 2022 and $38 million and $40 million for the nine months ended September 30, 2023 and 2022. As of September 30, 2023 and December 31, 2022, the cumulative amounts ceded under the LPT were $3.5 billion. The unrecognized deferred retroactive reinsurance benefit was $388 million and $425 million as of September 30, 2023 and December 31, 2022 and is included within Other liabilities on the Condensed Consolidated Balance Sheets.
NICO established a collateral trust account as security for its obligations to the Company. The fair value of the collateral trust account was $2.3 billion as of September 30, 2023. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the aggregate reinsurance limit as well as certain of NICO’s performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third-party reinsurers related to the majority of the Company’s A&EP claims.
Credit Risk for Ceded Reserves
The majority of the Company’s outstanding voluntary reinsurance receivables are due from reinsurers with financial strength ratings of A or higher. Receivables due from reinsurers with lower financial strength ratings are primarily due from captive reinsurers and are backed by collateral arrangements.

Note F. Future Policy Benefits Reserves
Future policy benefits reserves are related to the Company's run-off long term care business, which is included in the Life & Group segment.
The determination of Future policy benefits reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policy. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk. As a result of this variability, the Company’s future policy benefits reserves may be subject to material increases if actual experience develops adversely to the Company’s expectations.
The LFPB is computed using the net level premium method, which incorporates cash flow assumptions and discount rate assumptions. Under the net level premium method, the LFPB is equal to the present value of future benefits and claim settlement expenses less the present value of future net premiums. Net premiums are equal to gross premiums multiplied by the NPR. The NPR is generally the ratio of the present value of benefits and expense payments to the present value of gross premiums, expected over the lifetime of the policy. As a result of the modified retrospective adoption of ASU 2018-12, the Company’s NPR calculation incorporates the original locked in discount rate and the reserve balance as of the transition date of January 1, 2021.
The key cash flow assumptions used to estimate the LFPB are morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expenses. 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. Expense assumptions relate to claim adjudication. The Company has not elected the practical expedient that allows locking in the expense assumption. The discount rate is determined using the upper-medium grade fixed income instrument yield curve.
The Company has elected to update the NPR and the LFPB for actual experience on a quarterly basis. A quarterly assessment is also made as to whether evidence suggests that cash flow assumptions should be updated. Annually in the third quarter, actuarial analysis is performed on policyholder morbidity, persistency, premium rate increases and expense experience. This analysis, combined with judgment, informs the setting of updated cash flow assumptions used to estimate the LFPB. Actuarial analysis includes predictive modeling, actual to expected experience comparisons and trend analysis. Applicable industry research is also considered.
The cash flow assumption updates for the third quarter of 2023 resulted in an $8 million pretax increase in the LFPB. Persistency updates were unfavorable due to revisions to lapse rates. Morbidity updates were favorable driven by claim severity assumption updates, and there was a favorable impact from outperformance on premium rate assumptions. Adjusted to reflect the application of the LDTI accounting standard, the cash flow assumption updates for the third quarter of 2022 resulted in a $186 million pretax increase to the LFPB, primarily driven by the unfavorable impact of increased cost of care inflation offset by favorable premium rate assumptions.
Quarterly, to derive the upper-medium grade fixed income instrument yield discount rate assumption, the Company uses a published spot rate curve constructed from single-A rated U.S. dollar denominated corporate bonds. The Company uses linear interpolation to determine yield assumptions for tenors that fall between points for which observable rates are available. For cash flows that are projected to occur beyond the tenor for which market-observable rates are available, the Company applies judgment to estimate a normative rate which the Company grades to over 10 years.
Quarterly, the updated NPR is used to derive an updated LFPB as of the beginning of the current quarter measured at the original locked in discount rate. The updated LFPB is then compared to the existing carrying amount of the liability as of the same date (measured at the original locked in discount rate) to determine the re-measurement gain (loss), which is presented parenthetically within the Insurance claims and policyholders’ benefits line on the Condensed Consolidated Statements of Operations.

Table of Contents
Insurance contracts are grouped into cohorts according to issue year. Contracts assumed through reinsurance are generally included within the same cohorts as contracts issued directly by the Company, according to issue year. The issue year for assumed contracts is defined according to the date that the Company’s assumption of insurance risk incepted. For assumed contracts that were reinsured concurrently with the issuance of the underlying direct contract, issue year is defined as the year that the underlying policy was issued. For contracts that were already in-force when assumed by the Company, issue year is defined as the year in which the reinsurance agreement incepted. For group long term care business, issue year is defined as the year the individual insurance certificate was issued. Long term care is the Company's only long-duration product line, therefore, cohorts are not further disaggregated by product.

Note G. Legal Proceedings, Contingencies and Guarantees
The Company is a party to various claims and litigation incidental to its business, which, based on the facts and circumstances currently known, are not material to the Company's results of operations or financial position.
Guarantees
The Company has provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities issued by a previously owned subsidiary. As of September 30, 2023, the potential amount of future payments the Company could be required to pay under these guarantees was $1.5 billion, which will be paid over the lifetime of the annuitants. The Company does not believe any payment is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

Note J. Business Segments
The Company's property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International. These three segments are collectively referred to as Property & Casualty Operations. The Company's operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other.
The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2022. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs, Goodwill and Deferred non-insurance warranty acquisition expense and revenue are readily identifiable for individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Net investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense have been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.
In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio.
The performance of the Company's insurance operations is monitored by management through core income (loss), which is derived from certain income statement amounts. The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk.
Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses. The calculation of core income (loss) excludes net investment gains or losses because net investment gains or losses are generally driven by economic factors that are not necessarily reflective of our primary operations.

Item 2. Management's Discussion and Analysis (MD&A) of Financial Conditions 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 included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2022.
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 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 CNA's most recent Annual Report on Form 10-K on file with the Securities and Exchange Commission.
In evaluating the results of our Specialty, Commercial and International segments, we utilize the loss ratio, the 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. 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. 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 to the Condensed Consolidated Financial Statements included under Part I, Item 1.

CRITICAL ACCOUNTING ESTIMATES
The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the amount of revenues and expenses reported during the period. Actual results may differ from those estimates.
Our Condensed Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Condensed Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third-party professionals and various other assumptions that are believed to be reasonable under the known facts and circumstances.
The accounting estimates discussed below are considered by us to be critical to an understanding of our Condensed Consolidated Financial Statements as their application places the most significant demands on our judgment:
•Insurance Reserves
•Long Term Care Reserves
•Reinsurance and Insurance Receivables
•Valuation of Investments and Impairment of Securities
•Income Taxes
Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from our estimates and may have a material adverse impact on our results of operations, financial condition, equity, business, and insurer financial strength and corporate debt ratings.
See the Critical Accounting Estimates section of our Management's Discussion and Analysis of Financial Condition and Results of Operations included under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2022 for further information on the accounting estimates related to Reinsurance and Insurance Receivables, Valuation of Investments and Impairment of Securities and Income Taxes.
The information presented below restates in their entirety, as a result of the adoption of ASU 2018-12 and its impact on long term care reserves, the accounting estimates related to Insurance Reserves and Long Term Care Reserves included under the Critical Accounting Estimates section of our Management's Discussion and Analysis of Financial Condition and Results of Operations included under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2022. Further information on the long term care reserving process under the new guidance is included in Note A and Note F to the Condensed Consolidated Financial Statements included under Part I, Item I.
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 of our Annual Report on Form 10-K for the year ended December 31, 2022.
Long Term Care Reserves
Future policy benefits reserves for our long term care policies are based on certain assumptions, including morbidity, persistency (inclusive of mortality), 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.
Changes to our reserves could materially adversely impact our results of operations, financial condition and equity.

Prior period amounts presented in the financial statements have been adjusted to reflect application of the new guidance. See Note A to the Condensed Consolidated Financial Statements for additional information.
Three Month Comparison
Core income increased $246 million for the three months ended September 30, 2023 as compared with the same period in 2022. Core income for our Property & Casualty Operations increased $91 million primarily due to higher net investment income, improved underlying underwriting results, and lower catastrophe losses partially offset by lower favorable net prior year loss reserve development. Core loss for our Life & Group segment improved $163 million, while core loss for our Corporate & Other segment increased $8 million.
Catastrophe losses were $94 million for the three months ended September 30, 2023, primarily related to severe weather related events. Catastrophe losses were $114 million for the three months ended September 30, 2022, primarily related to severe weather related events, including $87 million for Hurricane Ian. Unfavorable net prior year loss reserve development of $13 million was recorded for the three months ended September 30, 2023 as compared with favorable net prior year loss reserve development of $17 million recorded for the three months ended September 30, 2022 related to our Specialty, Commercial and Corporate & Other segments. Further information on net prior year loss reserve development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.

Nine Month Comparison
Core income increased $351 million for the nine months ended September 30, 2023 as compared with the same period in 2022. Core income for our Property & Casualty Operations increased $173 million primarily due to higher net investment income and improved underlying underwriting results partially offset by lower favorable net prior year loss reserve development and higher catastrophe losses. Core loss for our Life & Group segment improved $144 million, while core loss for our Corporate & Other segment improved $34 million.
Catastrophe losses were $214 million for the nine months ended September 30, 2023, primarily related to severe weather related events. Catastrophe losses were $171 million for the nine months ended September 30, 2022, primarily related to severe weather related events, including $87 million for Hurricane Ian. Unfavorable net prior year loss reserve development of $44 million was recorded for the nine months ended September 30, 2023 as compared with favorable net prior year loss development of $2 million for the nine months ended September 30, 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 Condensed Consolidated Financial Statements included under Part I, Item 1.
Results for the three and nine months ended September 30, 2023 were impacted by unfavorable net pension costs related to our legacy United States of America (U.S.) pension plan 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 has resulted in an unfavorable impact on our expense ratio for the three and nine months ended September 30, 2023. The components of our net periodic pension cost (benefit) are presented in Note H to the Condensed Consolidated Financial Statements included under Part I, Item I.

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 Condensed Consolidated Financial Statements for additional information.
Three Month Comparison
Core loss decreased $163 million for the three months ended September 30, 2023 as compared with the same period in 2022. Both periods are inclusive of cash flow assumption updates as a result of the annual reserve review completed in the third quarter of each year. Results for the prior year quarter have been adjusted to reflect the application of the LDTI accounting standard and include an unfavorable impact from cash flow assumption updates in 2022.
The cash flow assumption updates for the three months ended September 30, 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 the three months ended September 30, 2022 resulted in a $186 million pretax increase to long term care reserves, primarily driven by the unfavorable impact of increased cost of care inflation 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 the three months ended September 30, 2023 and 2022.
Nine Month Comparison
Core loss decreased $144 million for the nine months ended September 30, 2023 as compared with the same period in 2022, primarily due to the annual reserve reviews performed in the third quarter of each year partially offset by long term care policy buyouts. Policy buyouts generally result in an unfavorable impact on core loss, as the cash payments are linked to higher statutory reserve levels. We expect to continue offering policy buyouts for the remainder of 2023 and into future years.
Future Policy Benefit Reserves
Annually in the third quarter, an actuarial analysis is performed on policyholder morbidity, persistency, premium rate increases and expense experience. This analysis, combined with judgment, informs the setting of updated cash flow assumptions used to estimate the liability for future policyholder benefits (LFPB). See Note F to the Condensed Consolidated Financial Statements included under Part I, Item 1 for further information on the reserving process.
The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our 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.

See Note A and Note F to the Condensed Consolidated Financial Statements for additional information.
(2) In conjunction with the adoption of LDTI, at January 1, 2023 we reclassified the long term care reserves for policyholders currently receiving benefits from Claim and claim adjustment expense to Future policy benefits. This change was applied retrospectively as of January 1, 2021.
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.

Pretax net investment losses decreased $58 million for the three months ended September 30, 2023 as compared with the same period in 2022 which reflects lower net losses on fixed maturity securities.
Pretax net investment losses decreased $61 million for the nine months ended September 30, 2023 as compared with the same period in 2022 driven by the favorable relative change in fair value of non-redeemable preferred stock.
Additionally, Derivatives, short term and other for the three months ended September 30, 2022 included a $35 million non-economic net loss related to the novation of a coinsurance agreement on our legacy annuity business in our Life & Group segment and the associated funds withheld embedded derivative. The coinsurance agreement was novated in the fourth quarter of 2022.
Further information on our investment gains and losses is set forth in Note C to the Condensed Consolidated Financial Statements included under Part I, Item 1.

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 September 30, 2023 the allowance for expected credit losses on our mortgage portfolio was $35 million, or 3.4% 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 September 30, 2023, these holdings had an estimated fair value of $437 million and net unrealized losses of $128 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.
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.

| September 30, 2023 |  | December 31, 2022
(In millions) | Estimated Fair Value |  | Effective Duration (In years) |  | Estimated Fair Value |  | Effective Duration (In years)
Investments supporting Life & Group | $ | 13,737 |  |  | 9.8 |  |  | $ | 14,511 |  |  | 9.9 |
Other investments | 26,459 |  |  | 4.6 |  |  | 25,445 |  |  | 4.7 |
Total | $ | 40,196 |  |  | 6.3 |  |  | $ | 39,956 |  |  | 6.6 |

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 of our Annual Report on Form 10-K for the year ended December 31, 2022.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our primary operating cash flow sources are premiums and investment income. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.
For the nine months ended September 30, 2023, net cash provided by operating activities was $1,765 million as compared with $1,990 million for the same period in 2022. The decrease in cash provided by operating activities was driven by higher net claim payments, which includes long term care policy buyouts of $160 million, and lower distributions from limited partnerships partially offset by an increase in premiums collected.
Cash flows from investing activities include the purchase and disposition of financial instruments, excluding those held as trading, and may include the purchase and sale of businesses, equipment and other assets not generally held for resale.
For the nine months ended September 30, 2023, net cash used by investing activities was $1,537 million as compared with net cash used by investing activities of $1,072 million for the same period in 2022. Net cash used by investing activities is primarily driven by cash available from operations and by other factors, such as financing activities.
Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, and outflows for stockholder dividends, repayment of debt and purchases of our common stock.
For the nine months ended September 30, 2023, net cash used by financing activities was $218 million as compared with $924 million for the same period in 2022. Financing activities for the periods presented include:
•During the nine months ended September 30, 2023, we paid dividends of $673 million and repurchased 550,000 shares of our common stock at an aggregate cost of $24 million.
•In the second quarter of 2023, we issued $400 million of 5.50% senior notes due June 15, 2033, and in the third quarter of 2023, we issued an additional $100 million of 5.50% senior notes due June 15, 2033.
•During the nine months ended September 30, 2022, we paid dividends of $874 million and repurchased 890,000 shares of our common stock at an aggregate cost of $39 million.

Table of Contents
Common Stock Dividends
Cash dividends of $2.46 per share on our common stock, including a special cash dividend of $1.20 per share, were declared and paid during the nine months ended September 30, 2023. On October 27, 2023, our Board of Directors declared a quarterly cash dividend of $0.42 per share, payable November 30, 2023 to stockholders of record on November 13, 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.
Liquidity
We believe that our present cash flows from operating, investing and financing activities are sufficient to fund our current and expected working capital and debt obligation needs and we do not expect this to change in the near term. There are currently no amounts outstanding under our $250 million senior unsecured revolving credit facility and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago (FHLBC).
Dividends from Continental Casualty Company (CCC) are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Illinois Department of Insurance (the Department), are determined based on the greater of the prior year's statutory net income or 10% of statutory surplus as of the end of the prior year, as well as timing and amount of dividends paid in the preceding twelve months. Additionally, ordinary dividends may only be paid from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of September 30, 2023, CCC was in a positive earned surplus position. CCC paid dividends of $770 million and $845 million during the nine months ended September 30, 2023 and 2022. The actual level of dividends paid in any year is determined after an assessment of available dividend capacity, holding company liquidity and cash needs as well as the impact the dividends will have on the statutory surplus of the applicable insurance company.
We have an effective 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.

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 (ASU 2018-12). The updated accounting guidance requires changes to the measurement and disclosure of long-duration contracts. For us, this includes our long term care business in the Life & Group segment. For a discussion of Accounting Standards, see Note A to the Condensed Consolidated Financial Statements included under Part I, Item 1.
Prior period amounts in the condensed consolidated financial statements have been adjusted to reflect application of ASU 2018-12. Core income for the third quarter of 2022 decreased $170 million from what was previously reported under legacy accounting guidance, primarily related to our third quarter 2022 annual review of cash flow reserving assumptions. Under legacy accounting guidance, the third quarter 2022 gross premium valuation assessment indicated a pretax margin of $125 million and no unlocking event occurred. Under the new guidance, favorable changes to the upper-medium grade fixed income instrument discount rate were recorded through Accumulated other comprehensive income quarterly, while the net unfavorable impact of increased cost of care inflation offset by favorable premium rate action assumptions was recorded in income. Excluding the third quarter of 2022, Core income did not change materially from what was reported prior to adoption of ASU 2018-12.
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. These risks and uncertainties include, but are not limited to, the following as well as those risks contained in the Risk Factors section of our 2022 Annual Report on Form 10-K:
Company-Specific Factors
•the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates sections of our 2022 Annual Report on Form 10-K and this report, and the Reserves - Estimates and Uncertainties section of our 2022 Annual Report on Form 10-K, 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 excess workers' compensation (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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
There were no material changes in our market risk components for the three months ended September 30, 2023. See the Quantitative and Qualitative Disclosures About Market Risk included in Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2022 for further information. Additional information related to portfolio duration is discussed in the Investments section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part I, Item 2.
Item 4. Controls and Procedures
The Company maintains a system of disclosure controls and procedures which are designed to ensure that information required to be disclosed by the Company in reports that it files or submits to the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including this report, is recorded, processed, summarized and reported on a timely basis. These disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to the Company's management on a timely basis to allow decisions regarding required disclosure.
As of September 30, 2023, the Company's management, including the Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective as of September 30, 2023.
There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15 (f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2023 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
