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

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.
