["Any forward-looking statements made in this financial supplement reflect Chubb Limited's current views with respect to future events and financial performance and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements involve risks and uncertainties which may cause actual results to differ materially from such statements. For example, forward-looking statements related to financial performance, including exposures, reserves and recoverables, could be affected by the frequency and severity of unpredictable catastrophic events, actual loss experience, uncertainties in the reserving or settlement process, currency exchange fluctuations, new theories of liability, judicial, legislative, regulatory and other governmental developments, litigation tactics and developments, investigation developments and actual settlement terms, the amount and timing of reinsurance receivable and credit developments among reinsurers."]
["Our forward-looking statements could also be affected by, among other things, competition, pricing and policy term trends, market acceptance, changes in demand, actual market developments, rating agency action, possible terrorism or the outbreak and effects of war, and such other factors identified in our filings with the Securities and Exchange Commission. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the dates on which they are made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise."]

[null,null,"Core operating income relates only to Chubb income, which excludes noncontrolling interests. It excludes from Chubb net income the after-tax impact of adjusted net realized gains (losses) and other, which include items described in this paragraph, and market risk benefits gains (losses). We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude adjusted net realized gains (losses) and market risk benefits gains (losses) because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities. In addition, we exclude the amortization of fair value adjustments on purchased invested assets and long-term debt related to certain acquisitions due to the size and complexity of these acquisitions. We also exclude integration expenses, which include legal and professional fees and all other costs directly related to acquisition integration activities. The costs are not related to the ongoing activities of the individual segments and are therefore included in Corporate and excluded from our definition of segment income. We believe these integration expenses are not indicative of our underlying profitability, and excluding these integration expenses facilitates the comparison of our financial results to our historical operating results. Additionally, we exclude the non-recurring tax benefit from the Bermuda Economic Transition Adjustment enacted in 2023 and adjusted in 2024 and subsequent years’ amortization of the related deferred tax asset, which we believe provides investors with a better view of our operating performance, enhances the understanding of the trends in the underlying business, improves comparability between periods and provides increased transparency compared to the prior presentation of the non-recurring tax benefit.

We believe the use of this measure is meaningful to show the tax on the underlying performance of our insurance business, by excluding the taxes on adjusted net realized gains (losses), market risk benefit gains (losses), amortization of the fair value adjustments related to purchased invested assets and long-term debt, integration expenses, the non-recurring tax benefit from the Bermuda Economic Transition Adjustment enacted in 2023 and subsequent years’ amortization of the related deferred tax asset.

Book value per share and tangible book value per share excluding accumulated other comprehensive income (loss) (AOCI), excludes AOCI from the numerator because it eliminates the effect of items that can fluctuate significantly from period to period, primarily based on changes in interest rates and foreign currency movement, to highlight underlying growth in book and tangible book value."]

Because these entities are investment companies, we are required to retain the investment company presentation in our consolidated results, which means, we include the net investing activities of these entities in our operating cash flows. Chubb has elected to remove the impact of net investing activities of consolidated investment companies from our operating cash flow as they may distort a reader’s analysis of our underlying operating cash flow related to the core insurance company operations. These net investing activities are more appropriately classified outside of operating cash flows, consistent with our consolidated investing activities. Accordingly, we believe that it is appropriate to adjust operating cash flow for the impact of consolidated investment products."]

[null,null,"Catastrophe losses (Cats): We generally define catastrophe loss events consistent with the definition of the Property Claims Service (PCS) for events in the U.S. and Canada. PCS defines a catastrophe as an event that causes damage of $25 million or more in insured losses and affects a significant number of insureds. For events outside of the U.S. and Canada, we generally use a similar definition. Catastrophe loss events are events that occurred in the current calendar year only. Changes in catastrophe loss estimates in the current calendar year that relate to loss events that occurred in previous calendar years are considered prior period development."]
