Basis of presentation

Basis of presentation

Chubb Limited is a holding company incorporated in Zurich, Switzerland. Chubb Limited, through its subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. Our results are reported through the following business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insurance, Overseas General Insurance, Global Reinsurance, and Life Insurance. Refer to Note 18 for additional information.

The interim unaudited consolidated financial statements, which include the accounts of Chubb Limited and its subsidiaries (collectively, Chubb, we, us, or our), have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and, in the opinion of management, reflect all adjustments necessary for a fair statement of the results and financial position for such periods. All significant intercompany accounts and transactions, including internal reinsurance transactions, have been eliminated.

The results of operations and cash flows for any interim period are not necessarily indicative of the results for the full year. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our 2022 Form 10-K.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents

Restricted cash

Restricted cash in the Consolidated balance sheets represents amounts held for the benefit of third parties and is legally or contractually restricted as to withdrawal or usage. Amounts include deposits with U.S. and non-U.S. regulatory authorities, trust funds set up for the benefit of ceding companies, and amounts pledged as collateral to meet financing arrangements.

The following table provides a reconciliation of cash and restricted cash reported within the Consolidated balance sheets that total to the amounts shown in the Consolidated statements of cash flows:

Accounting guidance adopted

Accounting guidance adopted in 2023

Targeted Improvements to the Accounting for Long-Duration Contracts

Effective January 1, 2023, we adopted new guidance on the accounting for long-duration contracts (LDTI). The new accounting guidance requires more frequent updating of assumptions and a standardized discount rate for the future policy benefit liability, a requirement to use the fair value measurement model for policies with market risk benefits, simplified amortization of deferred acquisition costs, and enhanced disclosures.

With the exception of market risk benefits, we adopted this guidance on a modified retrospective basis. Under the modified retrospective basis, the liability for future policy benefits is updated to remove any amounts related to changes to the original discount rate at January 1, 2021 (the transition date) in AOCI and future cash flow assumptions are applied to contracts in force. The liability for future policy benefits prior to the transition date continues to use the original discount rate (interest accretion rate). The guidance for long-duration contracts applicable to market risk benefits, primarily assumed reinsurance programs involving minimum benefit guarantees under variable annuity contracts, was adopted on a retrospective transition approach. Under the retrospective transition approach, we calculated the fair value of market risk benefits which were previously accounted for under an insurance accounting model and recognized an adjustment to retained earnings as of January 1, 2021.

On January 1, 2021, we recognized a cumulative effect adjustment and increased beginning retained earnings by $52 million, and decreased AOCI by $1.8 billion. Results for the prior reporting periods in this report are presented in accordance with the new guidance. We also adopted the required disclosures in Note 6 Deferred acquisition costs, Note 9 Future policy benefits, Note 10 Policyholders’ account balances, Note 11 Market risk benefits, and Note 12 Separate accounts.

The impact of adoption of the new guidance on our historical financial statements is as follows:

Deferred policy acquisition costs and value of business acquired

Deferred policy acquisition costs (DAC)

Policy acquisition costs on long-duration contracts are grouped by contract type and issue year into cohorts consistent with the grouping used in estimating the associated liability. Deferred policy acquisition costs are amortized on a constant level basis over the expected term of the related contracts to approximate straight-line amortization. The constant level basis used for amortization is the face amount in force and is projected using the same assumptions used in estimating the liability for future policy benefits. If those projected assumptions change in future periods, they will be reflected in the cohort level amortization basis at that time. Unexpected changes in the in-force portfolio, due to variances in mortality and lapse experience, are recognized over the contract term. Changes in future mortality and lapse assumptions are also recognized prospectively over the remaining expected contract term.

Future policy benefits

Future policy benefits

For traditional and limited-payment contracts, contracts are grouped into cohorts by contract type and issue year to determine a liability for future policy benefits. The future policy benefit liability (FPBL) is the present value of estimated future policy benefits to be paid to or on behalf of policyholders and certain related expenses less the present value of estimated future net premiums to be collected from policyholders, and is accrued as premium revenue is recognized. The valuation of this liability requires management to make estimates and assumptions regarding expenses, mortality, and persistency. Estimates are primarily based on historical experience. Actual results could differ materially from these estimates.

The liability is adjusted for differences between actual and expected experience. With the exception of the expense assumption, we review our future cash flow assumptions at least annually to determine if the net premium ratio (NPR), the mechanism used to record the liability as premium is earned, used to calculate the liability should be changed at that time. We have elected to use expense assumptions that are locked in at contract inception and are not subsequently reviewed or updated. Each quarter, we update the cash flows expected over the entire life of each cohort for actual historical experience and projected future cash

flows. These updated cash flows are used to calculate the revised NPR, which is used to derive an updated FPBL as of the beginning of the current reporting period, discounted at the original contract issuance discount rate. This amount is then compared to the carrying amount of the liability as of that same date, but before the updating of cash flow assumptions, to determine the current period change in FPBL. This current period change in the liability is the liability remeasurement gain or loss and is recorded in Policy benefits in the Consolidated statements of operations. In subsequent periods, the revised NPR is used to measure the FPBL until future revisions become required.

For traditional and limited-payment contracts, the discount rate assumption based on an upper-medium grade fixed-income instrument yield. An equivalent rate is derived based on A-credit-rated fixed-income instruments with similar duration to the liability. The discount rate assumption is updated quarterly and used to remeasure the liability at each reporting date, with the resulting change reflected in Other comprehensive income. For liability cash flows that are projected beyond the duration of market-observable A-credit-rated fixed-income instruments, we use the last market-observable yield level, as the basis for a linear interpolation to determine yield assumptions for durations that do not have market-observable yields.

Deferred profit liability

For limited-payment products, gross premiums received in excess of net premiums are deferred at initial recognition as a deferred profit liability (DPL) and recorded as a component of Future policy benefits in the Consolidated balance sheets. Net premiums are measured using actual cash flows and future cash flow assumptions consistent with those used in the measurement of the liability for future policy benefits and remeasured quarterly. The DPL is amortized in proportion to the discounted in-force policies. Interest is accreted on the balance of the DPL using the discount rate consistent with the interest accretion on the FPBL. The recalculated DPL, including adjusted amortization through the current period, is compared to the current carrying amount and the difference is recognized as an adjustment to Policy benefits in the Consolidated statements of operations as a remeasurement gain or loss.

Market Risk Benefit

Market risk benefits

Chubb reinsures various death and living benefit guarantees associated with variable annuities issued primarily in the United States, which are referred to as market risk benefits. These reinsurance contracts provide both protection to the ceding entity from other-than-nominal capital market risk and expose us to other-than-nominal capital market risk.

Market risk benefits are measured at fair value using a valuation model based on current net exposures, market data, our experience, and other factors. Changes in fair value are recognized in Market risk benefits gains (losses) in the Consolidated statements of operations, except the change in fair value due to a change in the instrument-specific credit risk, which is recognized in other comprehensive income. Refer to Note 11 for additional information.
