4. Fair value measurements

a) Fair value hierarchy

Fair value of financial assets and financial liabilities is estimated based on the framework established in the fair value accounting guidance. The guidance defines fair value as the price to sell an asset or transfer a liability (an exit price) in an orderly transaction between market participants and establishes a three-level valuation hierarchy based on the reliability of the inputs. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data.

The three levels of the hierarchy are as follows:

•Level 1 – Unadjusted quoted prices for identical assets or liabilities in active markets;

•Level 2 – Includes, among other items, inputs other than quoted prices that are observable for the asset or liability such as

interest rates and yield curves, quoted prices for similar assets and liabilities in active markets, and quoted prices for identical or similar assets and liabilities in markets that are not active; and

•Level 3 – Inputs that are unobservable and reflect management’s judgments about assumptions that market participants

would use in pricing an asset or liability.

We categorize financial instruments within the valuation hierarchy at the balance sheet date based upon the lowest level of inputs that are significant to the fair value measurement.

We use pricing services to obtain fair value measurements for the majority of our investment securities. Based on management’s understanding of the methodologies used, these pricing services only produce an estimate of fair value if there is observable market information that would allow them to make a fair value estimate. Based on our understanding of the market inputs used by the pricing services, all applicable investments have been valued in accordance with U.S. GAAP. We do not adjust prices obtained from pricing services. Refer to Note 4 a) of our 2025 Form 10-K for further information on the valuation and leveling of assets and liabilities measured at fair value.

Level 3 financial instruments

The following tables present a reconciliation of the beginning and ending balances of financial instruments measured at fair value using significant unobservable inputs (Level 3). Excluded from the tables below is the reconciliation of Market risk benefits, refer to Note 11 for additional information.

b) Financial instruments disclosed, but not measured, at fair value

Chubb uses various financial instruments in the normal course of its business. Our insurance contracts are excluded from fair value of financial instruments accounting guidance, and therefore, are not included in the amounts discussed below.

The carrying values of cash, other assets, other liabilities, and other financial instruments not included below approximated their fair values. Refer to Note 4 b) of our 2025 Form 10-K for information on the fair value methods and assumptions for private debt held-for-investment, repurchase agreements, short-term and long-term debt, and hybrid debt.

The following tables present fair value, by valuation hierarchy, and carrying value of the financial instruments not measured at fair value:
