Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General and significant accounting policies a) 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 17 for additional information. The interim unaudited Consolidated Financial Statements include the accounts of Chubb Limited and its subsidiaries (collectively, Chubb, we, us, or our), over which Chubb exercises control, including Huatai Group, our majority-owned subsidiary, and minority-owned entities such as variable interest entities (VIEs) in which Chubb is considered the primary beneficiary. Noncontrolling interests on the Consolidated Financial Statements represent the portion of majority-owned subsidiaries and VIEs in which we do not have direct equity ownership. These interim unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. 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 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 2025 Form 10-K. b) New Accounting Pronouncements Accounting guidance not yet adopted Disaggregation of Income Statement Expenses In November 2024, the FASB issued guidance that requires disclosure of specified information about certain costs and expenses in the notes to the financial statements. The guidance is effective for our 2027 annual reporting, and interim reporting periods beginning in 2028. Prospective application is required, with retrospective application permitted. We are evaluating the impact of this disclosure-only requirement.

Expected maturities could differ from contractual maturities because borrowers may have the right to call or prepay obligations, with or without call or prepayment penalties.

b) Gross unrealized loss

Fixed maturities in an unrealized loss position comprised both investment grade and below investment grade securities for which fair value declined, principally due to rising interest rates since the date of purchase. Refer to Note 1 f) in the 2025 Form 10-K for further information on factors considered in the evaluation of expected credit losses.

The following tables present, for available-for-sale (AFS) fixed maturities in an unrealized loss position (including securities on loan) that are not deemed to have expected credit losses, the aggregate fair value and gross unrealized loss by length of time the security has continuously been in an unrealized loss position:

At June 30, 2026, the tax benefit on certain unrealized losses in our investment portfolio was reduced by a valuation allowance of $285 million necessary due to limitations on the utilization of these losses for tax purposes. As part of evaluating whether it was more likely than not that we could record a tax benefit on these losses, we considered realized gains, carryback capacity and available tax planning strategies.

The following table presents a roll-forward of valuation allowance for expected credit losses on fixed maturities:

Included in all categories in the above table, except for Investment funds, are investments for which Chubb will never have the contractual option to redeem but receives distributions based on the liquidation of the underlying assets. Further, for all categories except for Investment funds, Chubb does not have the ability to sell or transfer the investments without the consent from the general partner of individual funds.


Investment Category:						Consists of investments in private equity funds:
Financial						targeting financial services companies, such as financial institutions and insurance services worldwide
Real assets						targeting investments related to hard physical assets, such as real estate, infrastructure, and natural resources
Distressed						targeting distressed corporate debt/credit and equity opportunities in the U.S.
Private credit						targeting privately originated corporate debt investments, including senior secured loans and subordinated bonds
Traditional						employing traditional private equity investment strategies, such as buyout and growth equity globally
Vintage						funds where the initial fund term has expired

Refer to Note 3 e) in our 2025 Form 10-K for further information on our private equity investments.

e) Restricted assets

Chubb is required to maintain assets on deposit with various regulatory authorities to support its insurance and reinsurance operations. These requirements are generally promulgated in the statutory regulations of the individual jurisdictions. The assets on deposit are available to settle insurance and reinsurance liabilities. Chubb is also required to restrict assets pledged under

repurchase agreements, which represent Chubb's agreement to sell securities and repurchase them at a future date for a predetermined price. We use trust funds in certain large reinsurance transactions where the trust funds are set up for the benefit of the ceding companies and generally take the place of letter of credit (LOC) requirements. We have investments in segregated portfolios primarily to provide collateral or guarantees for LOC and derivative transactions. Included in restricted assets at June 30, 2026, and December 31, 2025, are investments, primarily fixed maturities, totaling $18,955 million and $19,048 million, respectively, and cash of $243 million and $198 million, respectively.

The following table presents the components of restricted assets:


	June 30		December 31
(in millions of U.S. dollars)	2026		2025
Trust funds	$	8,529	$	8,461
Assets pledged under repurchase agreements	3,546		3,518
Deposits with U.S. regulatory authorities	2,575		2,598

Deposits with non-U.S. regulatory authorities and other	4,548		4,669

Total	$	19,198	$	19,246

f) Variable interest entities (VIEs)

Consolidated VIEs

We maintain investments in sponsored investment products that are considered VIEs. We have determined that we are the primary beneficiary and consolidate these investment products if we hold at least 10 percent ownership. Refer to Note 1 g) of our 2025 Form 10-K for further information on our consolidation criteria. The assets of these VIEs are not available to our creditors, and the investors in these VIEs have no recourse to Chubb in excess of the assets contained within the VIEs. Our economic exposures are limited to our investments based on our ownership interest in these VIEs. Our total exposure to these consolidated investment products represents the value of our economic ownership interest.

Unconsolidated VIEs

We recorded an investment in a reserved alternative investment fund (Fund) sponsored and managed by a third-party investment fund manager. The Fund is a variable interest entity; however, Chubb is not the primary beneficiary and does not consolidate the Fund because Chubb does not receive substantially all the risks and returns of the Fund. The carrying value of this investment at June 30, 2026, and December 31, 2025, was $5.3 billion and $5.4 billion, respectively, which approximates our maximum risk of loss. We have elected to account for this investment using the fair value option, classified as Equity securities on the Consolidated balance sheets. We elected the fair value option so that changes in fair value of the Fund are recorded in Net realized gains (losses) and dividends from the Fund are recorded as Net investment income when declared on the Consolidated statements of operations.

We also do not consolidate sponsored investment products where we have determined that we are not the primary beneficiary. The carrying value of these investments at June 30, 2026, and December 31, 2025, was $198 million and $70 million, respectively, and our maximum risk of loss approximates the carrying amount. These investments are classified primarily within Equity securities on the Consolidated balance sheets.

Fair value measurements

Fair Value Disclosures [Abstract]

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) in our 2025 Form 10-K for further information on the valuation and leveling of assets and liabilities measured at fair value.

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:

Prior Period Development

Prior period development (PPD) arises from changes to loss estimates recognized in the current year that relate to loss events that occurred in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years. Long-tail lines include lines such as workers' compensation, general liability, and financial lines; while short-tail lines include lines such as most property lines, energy, personal accident, and agriculture. The following table summarizes (favorable) and adverse PPD by segment:

Significant prior period movements by segment, principally driven by reserve reviews completed during each respective period, are discussed in more detail below. The remaining net development for long-tail lines and short-tail business for each segment and Corporate comprises numerous favorable and adverse movements across a number of lines and accident years, none of which is significant individually or in the aggregate.

North America Commercial P&C Insurance. Net favorable development for the three months ended June 30, 2026, included $69 million from long-tail lines, primarily from workers' compensation, due to lower-than-expected reported loss activity and our annual assessment of multi-claimant events, including industrial accidents, partially offset by net adverse development in commercial general liability, mainly due to higher-than-expected loss development. Net favorable development for the six months ended June 30, 2026, included $152 million from short-tail lines, primarily from surety, due to lower-than-expected loss development.

Net favorable development for the three months ended June 30, 2025, included $75 million from long-tail lines, primarily from the Risk Management business where PPD was favorable $163 million. This business underwrites workers' compensation, general liability and auto liability, and the favorable development was the net of lower-than-expected reported loss activity primarily on workers' compensation, partially offset by adverse development in general liability. This favorable development was partially offset by adverse development from other commercial auto liability portfolios which experienced higher-than-expected reported loss activity. Net favorable development for the six months ended June 30, 2025, included $193 million of favorable development from short-tail lines, primarily from surety, due to lower-than-expected loss development. Net favorable development for long-tail lines was the result of favorable development in workers' compensation and financial lines partially offset by adverse development in general casualty lines.

North America Personal P&C Insurance. Net favorable development for the three and six months ended June 30, 2026, included favorable development primarily in the auto physical damage line, due to lower-than-expected loss development.

Net favorable development for the three and six months ended June 30, 2025, included favorable development in the auto physical damage and recreational marine lines due to favorable loss emergence.

Overseas General Insurance. Net favorable development for the three and six months ended June 30, 2026, included $157 million and $288 million, respectively, from short-tail lines, primarily from favorable claim development in property.

Net favorable development for the three and six months ended June 30, 2025, included $112 million and $234 million, respectively, from short-tail lines, primarily from favorable claim development in property and marine lines.

Corporate. Net adverse development for the three and six months ended June 30, 2026 and 2025, was driven primarily by adverse development for molestation-related claims.

Separate accounts

Separate account assets represent segregated funds where investment risks are borne by the customers, except to the extent of certain guarantees made by Chubb. The assets that support variable contracts are measured at fair value and are reported as Separate account assets and corresponding liabilities are reported within Separate account liabilities on the Consolidated balance sheets. Policy charges assessed against the policyholders for mortality, administration, and other services are included in Net premiums earned on the Consolidated statements of operations.

The following table presents the aggregate fair value of Separate account assets, by major security type:

Cash surrender value (1)	$	6,960	$	6,101

(1)Cash surrender value represents the amount of the policyholder's account balances distributable at the balance sheet date less certain surrender charges.

Unearned revenue liabilities

Unearned revenue liabilities represent policy charges for services to be provided in future periods. The charges are reflected as deferred revenue and are generally amortized into income over the expected life of the contract using the same methodology, factors, and assumptions used to amortize deferred acquisition costs. Unearned revenue liabilities pertaining to both policyholders' account balances and separate accounts are recorded in Policyholders' account balances in the Consolidated balance sheets. The following table presents a roll-forward of unearned revenue liabilities:

Market risk benefits

Our reinsurance programs covering variable annuity guarantees, comprising guaranteed living benefits (GLB) and guaranteed minimum death benefits (GMDB), meet the definition of Market risk benefits (MRB). The following table presents a roll-forward of MRB:

Balance – end of period	$	505	$	609
Weighted-average age of policyholders (years)	75		74
Net amount at risk (2)	$	1,189	$	1,479

(1) Market movements are predominantly driven by changes in equities.

(2) The net amount at risk is defined as the present value of future claim payments assuming policy account values and guaranteed values are fixed at the valuation date, and reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty. No withdrawals, lapses, and mortality improvements are assumed in the projection. GLB-related risks contain conservative mortality and annuitization assumptions.

Excluded from the table above are MRB losses of $121 million and $103 million for the six months ended June 30, 2026 and 2025, respectively, reported in the Consolidated statements of operations, relating to the market risk benefits' economic hedge and other net cash flows. There is no reinsurance recoverable associated with our liability for MRB.

For MRB, Chubb estimates fair value using an internal valuation model which includes a number of factors including interest rates, equity markets, credit risk, current account value, market volatility, expected annuitization rates and other policyholder behavior, and changes in policyholder mortality. All reinsurance treaties contain claim limits, which are also factored into the valuation model.

(1)The weighted-average lapse and annuitization rates are determined by weighting each treaty's rates by the MRB contract's fair value.

The most significant policyholder behavior assumptions include lapse rates for MRBs, and GLB annuitization rates. Assumptions regarding lapse rates and GLB annuitization rates differ by treaty, but the underlying methodologies to determine rates applied to each treaty are comparable.

A lapse rate is the percentage of in-force policies surrendered in a given calendar year. All else equal, as lapse rates increase, ultimate claim payments will decrease.

The GLB annuitization rate is the percentage of policies for which the policyholder will elect to annuitize using the guaranteed benefit provided under the GLB. All else equal, as GLB annuitization rates increase, ultimate claim payments will increase, subject to treaty claim limits.

The effect of changes in key market factors on assumed lapse and annuitization rates reflect emerging trends using data available from cedants. The model and related assumptions are regularly re-evaluated by management and enhanced, as appropriate, based upon additional experience obtained related to policyholder behavior and availability of updated information such as market conditions, market participant assumptions, and demographics of in-force annuities. For detailed information on our lapse and annuitization rate assumptions, refer to Note 11 to the Consolidated Financial Statements of our 2025 Form 10-K.

Debt Disclosure [Abstract]
Debt Disclosure	Debt a) Chubb INA senior unsecured notes In March 2026, Chubb INA issued CHF200 million (approximately $254 million based on the foreign exchange rate at the date of issuance) aggregate principal amount of 1.02 percent senior unsecured notes due March 2032. Chubb INA's $1.5 billion of 3.35 percent senior unsecured notes due May 2026 were paid upon maturity. In May 2026, Chubb INA issued a series of senior unsecured notes denominated in Chinese yuan renminbi (CNH) comprising: •CNH2.5 billion (approximately $367 million based on the foreign exchange rate at the date of issuance) of 2.40 percent senior unsecured notes due 2031; and •CNH1.5 billion (approximately $220 million based on the foreign exchange rate at the date of issuance) of 2.85 percent senior unsecured notes due 2036. In May 2026, Chubb INA issued $1.0 billion of 5.30 percent senior unsecured notes due May 2036. In June 2026, Chubb INA issued a series of senior unsecured notes denominated in Canadian dollar (CAD) comprising: •CAD400 million (approximately $286 million based on the foreign exchange rate at the date of issuance) of 3.780 percent senior unsecured notes due 2031; and •CAD400 million (approximately $286 million based on the foreign exchange rate at the date of issuance) of 4.034 percent senior unsecured notes due 2033. In June 2026, the €575 million 0.875 percent senior unsecured notes due to mature in June 2027 were reclassified to short-term debt. Chubb INA's senior unsecured notes are guaranteed on a senior basis by Chubb Limited and rank equally with all of Chubb INA's other senior obligations. They also contain customary limitations on lien provisions as well as customary events of default provisions which, if breached, could result in the accelerated maturity of such senior debt. These notes are redeemable at any time at Chubb INA's option subject to a “make-whole” premium, as defined in the offering documentation. The notes are also redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. These notes do not have the benefit of any sinking fund.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Commitments and Contingencies Disclosure [Abstract]

Commitments, contingencies, and guarantees

6 Months Ended

Jun. 30, 2026

Commitments, contingencies, and guarantees

a) Derivative instruments

Chubb maintains positions in derivative instruments such as futures, options, swaps, and foreign currency forward contracts for which the primary purposes are to manage duration and foreign currency exposure, yield enhancement, or to obtain an exposure to a particular financial market. Chubb also maintains positions in convertible securities that contain embedded derivatives, and exchange-traded equity futures contracts on equity market indices to limit equity exposure in the market risk benefit (MRB) book of business. Derivative instruments are principally recorded in either Other assets (OA) or Accounts payable, accrued expenses, and other liabilities (AP) in the Consolidated balance sheets. Convertible securities are recorded in Fixed maturities available-for-sale (FM AFS). In addition, Chubb, from time to time, purchases to be announced mortgage-backed securities (TBAs) as part of its investing activities.

As a global company, Chubb entities transact business in multiple currencies. Our policy is to generally match assets, liabilities, and required capital for each individual jurisdiction in local currency, which would include the use of derivatives discussed below. Some of Chubb's derivatives satisfy hedge accounting requirements, as discussed below. We also consider economic hedging for planned cross border transactions.

The following table presents the balance sheet location, fair value in an asset or (liability) position, and notional value/payment provision of our derivative instruments:


				June 30, 2026								December 31, 2025
	Consolidated Balance Sheet Location	Fair Value				Notional Amount/ Payment Provision			Fair Value					Notional Amount/ Payment Provision

(1)Includes fair value of embedded derivatives.

(2)Related to MRB book of business.

At June 30, 2026, and December 31, 2025, net derivative liabilities of $105 million and $179 million, respectively, included in the table above were subject to a master netting agreement. The remaining derivatives included in the table above were not subject to a master netting agreement.

b) Hedge accounting

We designate certain derivatives as fair value hedges and net investment hedges for accounting purposes to hedge foreign currency exposure associated with portions of our euro denominated debt and the net investment in certain foreign subsidiaries, respectively. These derivatives comprise cross-currency swaps, which are agreements under which two counterparties exchange interest payments and principal denominated in different currencies at a future date. These hedges have been and are expected to be highly effective.

(i) Fair value hedges

Cross-currency swaps

Chubb holds certain cross-currency swaps designated as fair value hedges. The objective of these cross-currency swaps is to hedge the foreign currency risk on €1.7 billion, or approximately $2.0 billion at June 30, 2026, of euro denominated debt by converting cash flows back into the U.S. dollar.

These hedges are carried at fair value, with changes in fair value recorded in Other comprehensive income (OCI). The gains or losses on the fair value hedges offsetting the foreign currency remeasurement on the hedged euro denominated senior notes are reclassified from OCI into Net realized gains (losses), and an additional portion is reclassified into Interest expense as follows:


	Three Months Ended				Six Months Ended
	June 30				June 30
(pre-tax, in millions of U.S. dollars)	2026		2025		2026		2025
Gain (loss) recognized in OCI	$	16	$	141	$	(27)	$	115
Net realized gain (loss) reclassified from OCI	(23)		169		(57)		238
Interest expense reclassified from OCI	(4)		(5)		(9)		(9)
OCI gain (loss) after reclassifications	$	43	$	(23)	$	39	$	(114)

(ii) Net investment hedges

Cross-currency swaps

Chubb holds certain cross-currency swaps designated as net investment hedges. The objective of these cross-currency swaps is to hedge the foreign currency exposure in the net investments of certain foreign subsidiaries by converting cash flows from U.S. dollar to the British pound sterling, Japanese yen, Swiss franc, Chinese yuan renminbi, and Korean won. The hedged risk is designated as the foreign currency exposure arising between the functional currency of the foreign subsidiary and the functional currency of its parent entity.

These net investment hedges are carried at fair value, with changes in fair value recorded in Cumulative translation adjustments (CTA) within OCI, and a portion reclassified to Interest expense. The mark-to-market adjustments for foreign currency changes will remain in CTA until the underlying hedge subsidiary is deconsolidated or hedge accounting is discontinued.

In March 2026, in connection with the issuance of Swiss franc (CHF) 200 million senior unsecured notes and related designation as a net investment hedge, Chubb terminated its Swiss franc cross-currency swap with a notional amount of CHF95.8 million, originally maturing in March 2038. This termination resulted in a $42 million loss, which will remain in CTA until the underlying hedged subsidiary is deconsolidated.

Foreign denominated debt

Chubb designated the following foreign denominated debt as non-derivative net investment hedges:

•Chinese yuan renminbi term loans, $586 million at June 30, 2026

•Chinese yuan renminbi bonds, $1.3 billion at June 30, 2026

•Swiss franc senior unsecured notes, issued in Q1 2026, $250 million at June 30, 2026

•Canadian dollar bonds, issued in Q2 2026, $574 million at June 30, 2026

These non-derivative net investment hedges mitigate the foreign currency exposure in the net investments of certain foreign subsidiaries. Changes in the carrying value of the debt attributable to foreign currency revaluation are recorded in CTA within

OCI. These adjustments will remain in CTA until the underlying hedged subsidiary is deconsolidated or hedge accounting is discontinued.

The following table presents the OCI impact of derivative and non-derivative net investment hedges:


	Three Months Ended				Six Months Ended
	June 30				June 30

Total OCI gain (loss) after reclassifications	$	(8)	$	(151)	$	8	$	(135)

c) Derivative instruments not designated as hedges

Derivative instruments which are not designated as hedges are carried at fair value with changes in fair value recorded in Net realized gains (losses) or, for futures contracts on equities related to the MRB book of business, in Market risk benefits gains (losses) in the Consolidated statements of operations. The following table presents net gains (losses) related to derivative instrument activity in the Consolidated statements of operations:

(1)Related to MRB book of business.

(i) Foreign currency exposure management

A foreign currency forward contract (forward) is an agreement between participants to exchange specific currencies at a future date. Chubb uses forwards to minimize the effect of fluctuating foreign currencies as discussed above.

(ii) Duration management and market exposure

Futures

Futures contracts give the holder the right and obligation to participate in market movements, determined by the index or underlying security on which the futures contract is based. Settlement is made daily in cash by an amount equal to the change in value of the futures contract times a multiplier that scales the size of the contract. Exchange-traded futures contracts on money market instruments, notes and bonds are used in fixed maturity portfolios to more efficiently manage duration, as substitutes for ownership of the money market instruments, bonds, and notes without significantly increasing the risk in the

portfolio. Investments in futures contracts may be made only to the extent that there are assets under management not otherwise committed.

Exchange-traded equity futures contracts are used to limit exposure to a severe equity market decline, which would cause an increase in expected claims and, therefore, an increase in market risk benefit reserves.

Forwards

A fixed income forward contract (forward) is an agreement between participants to exchange a specific instrument at a fixed price at a future date. Chubb uses forwards to mitigate reinvestment risk of future written premiums.

Options

An option contract conveys to the holder the right, but not the obligation, to purchase or sell a specified amount or value of an underlying security at a fixed price. Option contracts are used in our investment portfolio as protection against unexpected shifts in interest rates, which would affect the duration of the fixed maturity portfolio. By using options in the portfolio, the overall interest rate sensitivity of the portfolio can be reduced. Option contracts may also be used as an alternative to futures contracts in the synthetic strategy as described above.

The price of an option is influenced by the underlying security, level of interest rates, expected volatility, time to expiration, and supply and demand.

The credit risk associated with the above derivative financial instruments relates to the potential for non-performance by counterparties. Although non-performance is not anticipated, in order to minimize the risk of loss, management monitors the creditworthiness of its counterparties and obtains collateral. The performance of exchange-traded instruments is guaranteed by the exchange on which they trade. For non-exchange-traded instruments, the counterparties are principally banks which must meet certain criteria according to our investment guidelines.

Other

Included within Other are derivatives intended to reduce potential losses which may arise from certain exposures in our insurance business. The economic benefit provided by these derivatives is similar to purchased reinsurance. For example, Chubb may, from time to time, enter into crop derivative contracts to protect underwriting results in the event of a significant decline in commodity prices.

(iii) Convertible security investments

A convertible security is a debt instrument that can be converted into a predetermined amount of the issuer’s equity. The convertible option is an embedded derivative within the host instruments which are classified in the investment portfolio as a fixed maturity security. Chubb purchases convertible securities for their total return and not specifically for the conversion feature.

(iv) TBA

By acquiring to be announced mortgage-backed securities (TBAs), we make a commitment to purchase a future issuance of mortgage-backed securities. For the period between purchase of the TBAs and issuance of the underlying security, we account for our position as a derivative in the Consolidated Financial Statements. Chubb purchases TBAs, from time to time, both for their total return and for the flexibility they provide related to our mortgage-backed security strategy.

(v) Futures contracts on equities

Under the MRB program, as the assuming entity, Chubb is obligated to provide coverage until the expiration or maturity of the underlying deferred annuity contracts or the expiry of the reinsurance treaty. We may recognize a loss for changes in fair value due to adverse changes in the capital markets (e.g., declining interest rates and/or declining U.S. and/or international equity markets). To mitigate adverse changes in the capital markets, we maintain positions in exchange-traded equity futures contracts, as noted under section "(ii) Futures" above. These futures increase in fair value when the S&P 500 index decreases (and decrease in fair value when the S&P 500 index increases). The net impact of gains or losses related to changes in fair value of the MRB liability and the exchange-traded equity futures are included in Market risk benefits gains (losses) in the Consolidated statements of operations.

d) Securities lending and secured borrowings

Chubb participates in a securities lending program operated by a third-party banking institution whereby certain assets are loaned to qualified borrowers and from which we earn an incremental return. The securities lending collateral can only be drawn down by Chubb in the event that the institution borrowing the securities is in default under the lending agreement. An

indemnification agreement with the lending agent protects us in the event a borrower becomes insolvent or fails to return any of the securities on loan. The collateral is recorded in Securities lending collateral and the liability is recorded in Securities lending payable in the Consolidated balance sheets.

The following table presents the carrying value of collateral held under securities lending agreements by investment category and remaining contractual maturity of the underlying agreements:


	Remaining contractual maturity
	June 30, 2026		December 31, 2025
(in millions of U.S. dollars)	Overnight and Continuous
Collateral held under securities lending agreements:
Cash	$	533	$	1,332
U.S. and local government securities	315		234
Non-U.S.	544		768
Corporate and asset-backed securities	96		62

Equity securities	382		104
Total	$	1,870	$	2,500
Gross amount of recognized liability for securities lending payable	$	1,870	$	2,500

At June 30, 2026, and December 31, 2025, our repurchase agreement obligations of $3,368 million and $3,324 million, respectively, were fully collateralized. In contrast to securities lending programs, the use of cash received is not restricted for the repurchase obligations. The fair value of the underlying securities sold remains in Fixed maturities available-for-sale or Other investments, and the repurchase agreement obligation is recorded in Repurchase agreements in the Consolidated balance sheets.

The following table presents the carrying value of collateral pledged under repurchase agreements by investment category and remaining contractual maturity of the underlying agreements:


	Remaining contractual maturity
	June 30, 2026						December 31, 2025
	Up to 30 Days		30-90 Days		Total			Up to 30 Days		30-90 Days		Greater than 90 Days		Total

(1)Per the repurchase agreements, the amount of collateral posted is required to exceed the amount of gross liability.

Refer to Note 14 e) in our 2025 Form 10-K for further information on our secured borrowing transactions.

e) Private equities

Private equities in the Consolidated balance sheets are investments in limited partnerships and partially-owned investment companies. Refer to Note 2 d) for information on our future private equity funding commitments.

f) Legal proceedings

Our insurance subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages and, in some jurisdictions, direct actions by allegedly-injured persons seeking damages from policyholders. These lawsuits, involving claims on policies issued by our subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in our loss and loss expense reserves. In addition to claims litigation, we are subject to lawsuits and regulatory actions in the normal course of business that do not arise from or directly relate to claims on insurance policies. This category of business litigation typically involves, among other things, allegations of underwriting errors or misconduct, employment claims, regulatory activity, or disputes arising from our business ventures. In the opinion of management, our ultimate liability for these matters could be, but we believe is not likely to be, material to our consolidated financial condition and results of operations.

g) Lease commitments

At June 30, 2026, and December 31, 2025, the right-of-use asset was $1,002 million and $1,025 million, respectively, recorded within Other assets, and the lease liability was $1,234 million and $1,214 million, respectively, recorded within Accounts payable, accrued expenses, and other liabilities on the Consolidated balance sheets. These leases consist principally of real estate operating leases that are amortized on a straight-line basis over the term of the lease, which expire at various dates.

Stockholders' Equity Note [Abstract]

Shareholders' equity

Shareholders’ equity

All of Chubb’s Common Shares are authorized under Swiss corporate law. Though the par value of Common Shares is stated in Swiss francs, Chubb continues to use U.S. dollars as its reporting currency for preparing the Consolidated Financial Statements. Under Swiss corporate law, dividends, including distributions from legal reserves or through a reduction in par value (par value reduction), must be stated in Swiss francs though dividend payments are made by Chubb in U.S. dollars. At June 30, 2026, our Common Shares had a par value of CHF 0.50 per share.

At our May 2026 annual general meeting, our shareholders approved an annual dividend for the following year of up to $4.08 per share, expected to be paid in four quarterly installments of $1.02 per share after the general meeting by way of distribution from capital contribution reserves, transferred to free reserves for payment. The Board of Directors (Board) will determine the record and payment dates at which the annual dividend may be paid until the date of 2027 annual general meeting, and is authorized to abstain from distributing a dividend at its discretion.

At our May 2025 and 2024 annual general meetings, our shareholders approved annual dividends for the following year of up to $3.88 per share and $3.64 per share, respectively, which were paid in four quarterly installments of $0.97 and $0.91 per share, respectively, at dates determined by the Board after the annual general meetings by way of a distribution from capital contribution reserves, transferred to free reserves for payment.

The following table presents dividend distributions per Common Share in Swiss francs (CHF) and U.S. dollars (USD):


	Three Months Ended						Six Months Ended

	2026			2025			2026			2025

Total dividend distributions per common share	0.80	$	1.02	0.81	$	0.97	1.55	$	1.99	1.62	$	1.88

Increases in Common Shares in treasury are due to open market repurchases of Common Shares and the surrender of Common Shares to satisfy tax withholding obligations in connection with the vesting of restricted stock and the forfeiture of unvested restricted stock. Decreases in Common Shares in treasury are principally due to grants of restricted stock, exercises of stock options, purchases under the Employee Stock Purchase Plan (ESPP), and share cancellations.

During March 2026 and 2025, Chubb completed share capital reductions by means of cancellation of 11,986,574 and 7,518,565 Common Shares purchased under our share repurchase program during 2025 and 2024, respectively. The capital reductions were completed in accordance with the capital band provision for authorized share capital increases and reductions by the Board set forth in the Articles of Association. During the six months ended June 30, 2026, 6,507,381 shares were repurchased, 11,986,574 shares were canceled, and 1,040,203 net shares were issued under employee share-based compensation plans. At June 30, 2026, 14,486,798 Common Shares remain in treasury.

Chubb Limited securities repurchase authorizations

In June 2023, the Board authorized the repurchase of up to $5.0 billion of Chubb Common Shares, effective July 1, 2023, with no expiration date. In May 2025, the Board determined to terminate the June 2023 authorization as of June 30, 2025 and concurrently authorized a new repurchase amount of up to $5.0 billion of Chubb Common Shares, effective July 1, 2025, with no expiration date. In May 2026, the Board determined to terminate the June 2025 authorization as of June 30, 2026 and concurrently authorized a new repurchase amount of up to $7.5 billion of Chubb Common Shares, effective July 1, 2026, with no expiration date. The following table presents repurchases of Chubb's Common Shares conducted in a series of open market transactions under the Board authorizations:

Compensation and Employee Benefit Plans [Text Block]

Share-based compensation	6 Months Ended
Share-based compensation	Jun. 30, 2026
Share-Based Payment Arrangement [Abstract]
Share-based compensation	Share-based compensation The Chubb Limited 2016 Long-Term Incentive Plan, as amended and restated (the Amended 2016 LTIP), permits grants of both incentive and non-qualified stock options principally at an option price per share equal to the grant date fair value of Chubb's Common Shares. Stock options are generally granted with a 3-year vesting period and a 10-year term. Stock options typically vest in equal annual installments over the respective vesting period, which is also the requisite service period. On March 2, 2026, Chubb granted 1,070,510 stock options with a weighted-average grant date fair value of $87.84 each. The fair value of the options issued is estimated on the grant date using the Black-Scholes option pricing model. The Amended 2016 LTIP also permits grants of service-based restricted stock and restricted stock units as well as performance shares and performance stock units. Under the Chubb Deferred Stock Unit Plan, a sub-plan of the Amended 2016 LTIP, eligible participants may defer vested performance stock units and restricted stock units to the extent such awards are U.S.-allocated compensation. Chubb generally grants service-based restricted stock and restricted stock units with a 4-year vesting period, based on a graded vesting schedule. Performance shares and performance stock units granted comprise both target and premium awards that cliff vest at the end of a 3-year performance period based on tangible book value (Chubb shareholders' equity less goodwill and intangible assets attributable to Chubb, net of tax) per share growth and P&C combined ratio compared to a defined group of peer companies. Premium awards are subject to an additional vesting provision based on total shareholder return compared to the peer group. Stock and unit awards are principally granted at market close price on the grant date. On March 2, 2026, Chubb granted 102,036 service-based restricted stock, 670,919 service-based restricted stock units, 90,078 performance shares, and 251,832 performance stock units to employees and officers with a grant date fair value of $342.76 each. Each service-based restricted stock unit and performance stock unit represents our obligation to deliver to the holder one Common Share upon vesting (or the end of the deferral period, if the unit is under the Chubb Deferred Stock Unit Plan).

Equity in net income of partially-owned entities includes our share of net income or loss, both underlying operating income and mark-to-market movement, related to partially-owned investment companies (private equity) where we own more than three

percent, and partially-owned insurance companies. This line item includes mark-to-market gains (losses) on private equities of $6 million and $33 million for the three and six months ended June 30, 2026 respectively, and $540 million and $513 million, respectively, for the prior year periods.

Also included in Other income and expense are gains (losses) from fair value changes in separate account assets that do not qualify for separate account treatment under U.S. GAAP. The offsetting movement in the separate account liabilities is included in Policy benefits in the Consolidated statements of operations.

Asset management and performance fee revenue and expense primarily relate to the management of third-party assets by Huatai's asset management business, which is unrelated to Huatai Group's core insurance operations. These revenues and expenses are recognized in the period in which the services are performed and, for certain asset performance fees, to the extent it is probable that a significant reversal will not occur.

Certain federal excise and capital taxes incurred as a result of capital management initiatives are included in Other income and expense as these are considered capital transactions and are excluded from underwriting results. Bad debt expense for uncollectible premiums is also included in Other income and expense.

Segment Reporting [Abstract]

Segment information

Chubb operates through six 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. These segments distribute their products through various forms of brokers, agencies, and direct marketing programs. All business segments have established relationships with reinsurance intermediaries.

Segment performance is reviewed by the Chief Executive Officer of Chubb Ltd, our Chief Operating Decision Maker (CODM). The CODM is ultimately responsible for evaluating the performance of our six business segments, making strategic operating decisions, and allocating resources. The financial results of our operations are reported in a manner consistent with results reviewed by the CODM in reviewing and assessing the performance of our six business segments. Excluding our Life Insurance segment, the CODM uses Underwriting income (loss) as a basis for segment performance. Chubb calculates Underwriting income (loss) by subtracting Losses and loss expenses, Policy benefits, Policy acquisition costs, and Administrative expenses from Net premiums earned. For both our P&C and Life Insurance segments, another measure of segment performance is Segment income (loss). Segment income (loss) includes Underwriting income (loss), Net investment income (loss), amortization of purchased intangibles acquired by the segment, and other operating income and expense items such as each segment's share of the operating income (loss) related to partially-owned entities, and miscellaneous income and expense items for which the segments are held accountable. We determined that this definition of Segment income (loss) is appropriate and aligns with how the business is managed. We continue to evaluate our segments as our business continues to evolve and may further refine our segments and Segment income (loss) measures.

Revenue and expenses managed at the corporate level, including Net realized gains (losses), Market risk benefits gains (losses), Interest expense, Integration expenses and severance, Income tax expense, and Net income (loss) attributable to noncontrolling interests are reported within Corporate. Integration expenses and severance are one-time costs that are directly attributable to third-party consulting fees, employee-related retention costs, and other professional and legal fees, as well as severance expenses incurred as part of transformation initiatives to enhance operational efficiency. These items are not allocated to the segment level as they are one-time in nature and are not related to the ongoing business activities of the segment. The CODM does not manage segment results or allocate resources to segments when considering these costs, and therefore Integration expenses and severance are excluded from our definition of Segment income (loss).

Certain items are presented in a different manner for segment reporting purposes than in the Consolidated Financial Statements, including:

•Losses and loss expenses include realized gains and losses on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing impacts underwriting results. We view gains and losses on these derivatives as part of the results of our underwriting operations, and therefore, realized gains (losses) from these derivatives are reclassified to losses and loss expenses.

•Policy benefits include fair value changes on separate accounts that do not qualify for separate accounting under U.S. GAAP. These gains and losses have been reclassified from Other (income) expense to Policy benefits. Policy benefits also include the impact of realized gains and losses on investment portfolios supporting certain participating policies.

These realized gains and losses have been reclassified from net realized gains (losses) to policy benefits. This presentation better reflects the gains and losses from fair value changes in separate account assets and liabilities, and the economics of the participating policies by connecting the investment performance that is shared with policyholders to the liability.

•Net investment income includes investment income reclassified from Other (income) expense related to partially-owned investment companies (private equity partnerships) where our ownership interest is in excess of three percent. We view investment income from these equity-method private equity partnerships as Net investment income for segment reporting purposes.

The following tables present the Statement of Operations by segment:

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 17 for additional information. The interim unaudited Consolidated Financial Statements include the accounts of Chubb Limited and its subsidiaries (collectively, Chubb, we, us, or our), over which Chubb exercises control, including Huatai Group, our majority-owned subsidiary, and minority-owned entities such as variable interest entities (VIEs) in which Chubb is considered the primary beneficiary. Noncontrolling interests on the Consolidated Financial Statements represent the portion of majority-owned subsidiaries and VIEs in which we do not have direct equity ownership. These interim unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. 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 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 2025 Form 10-K

Fair value measurements (Fair Value Measurement Policy) (Policies)	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement, Policy	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.

Weighted-average age of policyholders (years)	75		74
Net amount at risk (2)	$	1,189	$	1,479

(1) Market movements are predominantly driven by changes in equities.

(2) The net amount at risk is defined as the present value of future claim payments assuming policy account values and guaranteed values are fixed at the valuation date, and reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty. No withdrawals, lapses, and mortality improvements are assumed in the projection. GLB-related risks contain conservative mortality and annuitization assumptions.

Schedule Of Significant Unobservable Inputs Used In Level 3 Liability Valuations

For MRB, Chubb estimates fair value using an internal valuation model which includes a number of factors including interest rates, equity markets, credit risk, current account value, market volatility, expected annuitization rates and other policyholder behavior, and changes in policyholder mortality. All reinsurance treaties contain claim limits, which are also factored into the valuation model.

The net amount at risk is defined as the present value of future claim payments assuming policy account values and guaranteed values are fixed at the valuation date, and reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty. No withdrawals, lapses, and mortality improvements are assumed in the projection. GLB-related risks contain conservative mortality and annuitization assumptions.
