Property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (“IBNR”) claims as of the reporting date. Reserve projections are based primarily on detailed analysis of the facts in each case, experience with similar cases and various historical development patterns. Consideration is given to historical patterns such as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and economic conditions including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.

Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers’ compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the 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 the Company’s results of operations and/or equity. Catastrophe losses, net of reinsurance, of $114 million and $178 million were recorded for the three months ended September 30, 2022 and 2021 and $171 million and $357 million were recorded for the nine months ended September 30, 2022 and 2021. Catastrophe losses for the three and nine months ended September 30, 2022 were driven primarily by severe weather related events, including $87 million for Hurricane Ian. Catastrophe losses for the three months ended September 30, 2021 included $114 million for Hurricane Ida. Catastrophe losses for the nine months ended September 30, 2021 were driven by severe weather related events, primarily Hurricane Ida and Winter Storms Uri and Viola.

Unfavorable development in property and other was due to higher than expected claim severity in CNA’s medical treatment business mostly offset by favorable development due to lower than expected loss emergence across multiple accident years in commercial.

In 2010, Continental Casualty Company (“CCC”) together with several insurance subsidiaries completed a transaction with National Indemnity Company (“NICO”), a subsidiary of Berkshire Hathaway Inc., under which substantially all of their legacy A&EP liabilities were ceded to NICO through a loss portfolio transfer (“LPT”). At the effective date of the transaction, approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves were ceded to NICO under a retroactive reinsurance agreement with an aggregate limit of $4.0 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. NICO was paid a reinsurance premium of $2.0 billion and billed third party reinsurance receivables related to A&EP claims with a net book value of $215 million were transferred to NICO, resulting in total consideration of $2.2 billion.

In years subsequent to the effective date of the LPT, adverse prior year development on A&EP reserves was recognized 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 a change in the estimate of A&EP reserves is recognized 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 Consolidated Condensed Statements of Operations.

The impact of the LPT on the Consolidated Condensed Statements of Operations was the recognition of a retroactive reinsurance benefit of $17 million and $8 million for the three months ended September 30, 2022 and 2021 and $40 million and $30 million for the nine months ended September 30, 2022 and 2021. As of September 30, 2022 and December 31, 2021, the cumulative amounts ceded under the LPT were $3.4 billion. The unrecognized deferred retroactive reinsurance benefit was $389 million and $429 million as of September 30, 2022 and December 31, 2021 and is included within Other liabilities on the Consolidated Condensed Balance Sheets.

NICO established a collateral trust account as security for its obligations under the LPT. The fair value of the collateral trust account was $2.3 billion as of September 30, 2022. 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 A&EP claims.

The majority of CNA’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.

CNA’s Life & Group business includes its run-off long term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long term care policies provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and CNA has the ability to increase policy premiums, subject to state regulatory approval.

CNA maintains both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for its Life & Group business. Claim and claim adjustment expense reserves consist of estimated reserves for long term care policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported. In developing the claim and claim adjustment expense reserve estimates for long term care policies, CNA’s actuaries perform a detailed claim reserve review on an annual basis. The review analyzes the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. In addition, claim and claim adjustment expense reserves are also maintained for the structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for structured settlement obligations, CNA’s actuaries review mortality experience on an annual basis. CNA’s recorded claim and claim adjustment expense reserves reflect management’s best estimate after incorporating the results of the most recent reviews.

CNA’s most recent annual claim reserve reviews were completed in the third quarter of 2022. The long term care claim reserve review resulted in a $25 million pretax reduction in reserves driven by a $107 million favorable impact from the release of all remaining IBNR reserves established during 2020 and 2021 in response to the COVID-19 pandemic partially offset by an $82 million unfavorable impact from higher claim severity, including utilization and cost of care inflation, than anticipated in the reserve estimates. The structured settlement claim reserve review resulted in a $5 million pretax reduction in reserves due to discount rate assumption changes. CNA’s 2021 annual claim reserve reviews were completed in the third quarter of 2021 resulting in a $40 million pretax reduction in long term care reserves primarily due to lower claim severity than anticipated in the reserve estimates and a $2 million pretax increase in the structured settlement claim reserves primarily due to lower discount rate assumptions and mortality assumption changes.

Future policy benefit reserves consist of active life reserves related to CNA’s long term care policies for policyholders that are not currently receiving benefits and represent the present value of expected future benefit payments and expenses less expected future premium. The determination of these reserves requires management to make estimates and assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk.

The actuarial assumptions that CNA 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, CNA’s long term care reserves may be subject to material increases if actual experience develops adversely to CNA’s expectations.

Annually, in the third quarter, CNA 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 existing assumptions are unlocked and future policy benefit reserves are increased to the greater amount. Any such increase is reflected in the Company’s results of operations in the period in which the need for such adjustment is determined. If the GPV required reserves are less than the existing recorded reserves, assumptions remain locked in and no adjustment is made.
