NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
Chubb Limited and Subsidiaries
1. 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, including internal reinsurance transactions, have been eliminated.
On July 1, 2023, Chubb discontinued equity method accounting for its investment in Huatai Group upon obtaining a controlling interest and applied consolidation accounting. Therefore, effective July 1, 2023, business activity for, and the financial position of, Huatai Group is reported at 100 percent on the Consolidated Financial Statements. At June 30, 2024, and December 31, 2023, our aggregate ownership interest in Huatai Group was approximately 85.5 percent and 76.5 percent, respectively. The relevant amounts attributable to shareholders other than Chubb are reflected in the Consolidated Financial Statements under the captions Noncontrolling interests, Net income (loss) attributable to noncontrolling interests, and Comprehensive income (loss) attributable to noncontrolling interests. Refer to Note 2 for additional information on the acquisition of Huatai Group.
Huatai Group's life insurance and asset management businesses are included in the Life Insurance segment, and Huatai Group's P&C business is included in the Overseas General Insurance segment. Results for Huatai Group's non-insurance operations, comprising real estate and holding company activity, are included in Corporate.
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 2023 Form 10-K.
b) Debt
On March 7, 2024, Chubb INA Holdings LLC (Chubb INA) issued $1.0 billion of 5.0 percent senior notes due March 2034. These senior unsecured notes are guaranteed on a senior basis by Chubb Limited and they 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 senior notes are redeemable at any time at Chubb INA's option subject to a “make-whole” premium (the present value of the remaining principal and interest discounted at the applicable comparable government bond rate plus 0.15 percent). 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.
Chubb INA's $700 million of 3.35 percent senior notes due May 2024 was paid upon maturity.
c) New Accounting Pronouncements
Accounting guidance not yet adopted
Improvements to Reportable Segment Disclosures
In November 2023, the Financial Accounting Standards Board (FASB) issued guidance that requires expanded reportable segment disclosures, primarily related to significant segment expenses which are regularly provided to the chief operating decision maker. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024. Retrospective application is required. We are currently evaluating the impact of this disclosure-only requirement.

Chubb Limited and Subsidiaries
Improvements to Income Tax Disclosures
In December 2023, the FASB issued guidance that requires expanded income tax disclosures, including the disaggregation of existing disclosures related to the tax rate reconciliation and income taxes paid. The guidance is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. We are currently evaluating the impact of this disclosure-only requirement.
2. Acquisitions
Healthy Paws
On May 31, 2024, we acquired the business of Healthy Paws Pet Insurance LLC, a managing general agent specializing in pet insurance, from Aon plc for approximately $300 million in cash. We recognized goodwill of $256 million and intangible assets of $39 million from this acquisition. Chubb has been the exclusive underwriter of Healthy Paws since 2013. The transaction positions Chubb to expand in a niche market with substantial growth potential. This business is assigned to the North America Commercial Insurance segment.
Huatai Group
Huatai Insurance Group Co., Ltd. (Huatai Group) is a Chinese financial services holding company and the parent company of, among others, Huatai Property & Casualty Insurance Co., Ltd. (Huatai P&C), Huatai Life Insurance Co., Ltd. (Huatai Life), Huatai Asset Management Co., Ltd., and Huatai Baoxing Fund Management Co., Ltd., of which Huatai Group owns 100 percent, 80 percent, 91 percent, and 85 percent, respectively (collectively, Huatai).
On July 1, 2023, Chubb increased ownership interest from approximately 64.2 percent to approximately 69.6 percent. At that time, Chubb discontinued the equity method of accounting and applied consolidation accounting. Refer to Note 2 to the Consolidated Financial Statements in our 2023 Form 10-K for additional information.
In the first quarter of 2024, we closed on incremental ownership interests of approximately 9.0 percent for $555 million, $319 million of which was previously paid prior to 2024, and $236 million was paid in 2024. Our aggregate ownership interest in Huatai Group was approximately 85.5 percent as of June 30, 2024. Chubb has outstanding agreements for approximately 0.6 percent of incremental ownership interests, pending completion of certain closing conditions. We have paid deposits of $12 million related to these outstanding agreements, with approximately $24 million remaining to be paid upon closing, based on current exchange rates.
The acquisition of a controlling majority interest in Huatai Group on July 1, 2023, generated $3,458 million of Goodwill, attributable to expected growth and profitability, and $1,655 million of Other intangible assets. None of the goodwill is expected to be deductible for income tax purposes. Additionally, the acquisition generated $309 million of Value of business acquired (VOBA). Chubb financed the transaction through available cash on hand. Direct costs related to the acquisition are immaterial, and were expensed as incurred. These include one-time costs that are directly attributable to third-party consulting fees and other professional and legal fees related to the acquisition.
The following table summarizes the fair value of the assets acquired and liabilities assumed on July 1, 2023.

At June 30, 2024, the tax benefit on certain unrealized losses in our investment portfolio was reduced by a valuation allowance of $610 million necessary due to limitations on the utilization of these losses. As part of evaluating whether it was more likely than not that we could realize these losses, we considered realized gains, carryback ability and available tax planning strategies.

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

Investment funds employ various investment strategies, such as long/short equity and arbitrage/distressed. Included in this category are investments for which Chubb has the option to redeem at agreed upon value as described in each investment fund’s subscription agreement. Depending on the terms of the various subscription agreements, investment fund investments may be redeemed monthly, quarterly, semi-annually, or annually. If Chubb wishes to redeem an investment fund investment, it must first determine if the investment fund is still in a lock-up period (a time when Chubb cannot redeem its investment so that the investment fund manager has time to build the portfolio). If the investment fund is no longer in its lock-up period, Chubb must then notify the investment fund manager of its intention to redeem by the notification date prescribed by the subscription agreement. Subsequent to notification, the investment fund can redeem Chubb’s investment within several months of the notification. Notice periods for redemption of the investment funds are up to 270 days. Chubb can redeem its investment funds without consent from the investment fund managers.
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

f) Variable interest entities (VIEs)
Consolidated VIEs
Certain subsidiaries of Huatai Group are the investment manager of, and maintain investments in, sponsored investment products that are considered variable interest entities. 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 2023 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 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, 2024, and December 31, 2023, was $215 million and $153 million, respectively, and our maximum risk of loss approximates the carrying amount. These investments are classified within Equity securities on the Consolidated balance sheets.
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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries
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. The following is a description of the valuation techniques and inputs used to determine fair values for financial instruments carried at fair value, as well as the general classification of such financial instruments pursuant to the valuation hierarchy.
Fixed maturities
We use pricing services to estimate fair value measurements for the majority of our fixed maturities. The pricing services use market quotations for fixed maturities that have quoted prices in active markets; such securities are classified within Level 1. For fixed maturities other than U.S. Treasury securities that generally do not trade on a daily basis, the pricing services prepare estimates of fair value measurements using their pricing applications or pricing models, which include available relevant market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. Additional valuation factors that can be taken into account are nominal spreads, dollar basis, and liquidity adjustments. The pricing services evaluate each asset class based on relevant market and credit information, perceived market movements, and sector news. The market inputs used in the pricing evaluation, listed in the approximate order of priority include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. The extent of the use of each input is dependent on the asset class and the market conditions. Given the asset class, the priority of the use of inputs may change, or some market inputs may not be relevant. Additionally, fixed maturities valuation is more subjective when markets are less liquid due to the lack of market-based inputs (i.e., stale pricing) and may require the use of models to be priced. The lack of market-based inputs may increase the potential that an investment's estimated fair value is not reflective of the price at which an actual transaction would occur. The overwhelming majority of fixed maturities are classified within Level 2 because the most significant inputs used in the pricing techniques are observable. For a small number of fixed maturities, we obtain a single broker quote (typically from a market maker). Due to the disclaimers on the quotes that indicate that the price is indicative only, we include these fair value estimates in Level 3.
Equity securities
Equity securities with active markets are classified within Level 1 as fair values are based on quoted market prices. For equity securities in markets which are less active, fair values are based on market valuations and are classified within Level 2. Equity securities for which pricing is unobservable are classified within Level 3.
Short-term investments
Short-term investments, which comprise securities due to mature within one year of the date of purchase that are traded in active markets, are classified within Level 1 as fair values are based on quoted market prices. Securities such as commercial paper and discount notes are classified within Level 2 because these securities are typically not actively traded due to their approaching maturity, and as such, their cost approximates fair value. Short-term investments for which pricing is unobservable are classified within Level 3.
Private equities
Fair values for Private equities including investments in partially-owned investment companies, investment funds, and limited partnerships are based on their respective NAV and are excluded from the fair value hierarchy table below.
Other investments
Certain of our long-duration contracts are supported by assets that do not qualify for separate account treatment under U.S. GAAP. These assets primarily comprise mutual funds, classified within Level 1 in the valuation hierarchy on the same basis as other equity securities traded in active markets. Other investments principally include fixed maturities carried at fair value with changes in fair value recorded through Net realized gains (losses) on the Consolidated statements of operations. These fixed maturities principally relate to the Huatai investment portfolio, including those portfolios supporting certain participating policies, and are classified within Level 2. Also included are life insurance policies collateralizing investments held in rabbi trusts maintained by Chubb for deferred compensation plans and supplemental retirement plans. These policies are carried at cash surrender value and are classified in the valuation hierarchy within Level 2.
Securities lending collateral
The underlying assets included in Securities lending collateral in the Consolidated balance sheets are fixed maturities which are classified in the valuation hierarchy on the same basis as other fixed maturities. Excluded from the valuation hierarchy is the corresponding liability related to Chubb’s obligation to return the collateral plus interest as it is reported at contract value and not fair value in the Consolidated balance sheets.

Investment derivatives
Actively traded investment derivative instruments, including futures, options, and forward contracts are classified within Level 1 as fair values are based on quoted market prices. The fair value of cross-currency swaps and interest rate swaps is based on market valuations and is classified within Level 2. These derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets.
Derivatives designated as hedging instruments
Certain of our derivatives are cross-currency swaps designated as fair value and net investment hedging instruments. The fair value of cross-currency swaps and interest rate swaps is based on market valuations and is classified within Level 2. Investment derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets.
Other derivative instruments
We maintain positions in exchange-traded equity futures contracts designed to limit exposure to a severe equity market decline, which would cause an increase in expected market risk benefits (MRB) claims, and therefore, an increase in MRB reserves. Our positions in exchange-traded equity futures contracts are classified within Level 1. The fair value of the majority of the remaining positions in other derivative instruments is based on significant observable inputs including equity security and interest rate indices. Accordingly, these are classified within Level 2. Other derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets. Chubb also maintains positions in convertible securities that contain embedded derivatives. Convertible securities are recorded in either Fixed maturities available-for-sale (FM AFS) or Equity securities (ES) and are classified as either Level 1 of Level 2 depending on the underlying investment.
Separate account assets
Separate account assets represent segregated funds where investment risks are borne by the customers, except to the extent of certain guarantees made by Chubb. Separate account assets principally comprise mutual funds classified within Level 1 in the valuation hierarchy on the same basis as other equity securities traded in active markets. Separate account assets also include fixed maturities classified within Level 2 because the most significant inputs used in the pricing techniques are observable. Excluded from the valuation hierarchy are the corresponding liabilities as they are reported at contract value and not fair value in the Consolidated balance sheets.

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 and six months ended June 30, 2024, included $288 million and $338 million, respectively, from workers' compensation due to lower-than-expected loss experience and our annual assessment of multi-claimant events, including industrial accidents. The favorable development was partially offset by net adverse development of $117 million and $167 million, respectively, in commercial auto liability mainly due to higher-than-expected loss development and severity trend. Development for the six months ended June 30, 2024, included $144 million of favorable development in surety, property and marine lines, partially offset by net adverse development of $97 million in commercial excess and umbrella lines.
Net favorable development for the three and six months ended June 30, 2023 included $264 million and $308 million, respectively, from workers' compensation lines due to lower-than-expected loss experience and our annual assessment of multi-claimant events, including industrial accidents. The favorable development was partially offset by net adverse development of $119 million and $125 million, respectively, in commercial auto liability due to adverse reported loss experience.
Overseas General Insurance. Net favorable development for the three months ended June 30, 2024 included favorable claim development, mainly in marine and property lines. Net favorable development for the six months ended June 30, 2024 included favorable development of $85 million in property and $73 million in marine.
Net favorable development for the three months ended June 30, 2023 included favorable claim development in short-tail property and casualty and A&H. Net favorable development for the six months ended June 30, 2023 included $110 million of favorable catastrophe development and non-catastrophe property loss emergence.
Corporate. Net adverse development for the three and six months ended June 30, 2024 and 2023 was driven primarily by molestation-related claims development.

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:

| June 30 |  | June 30
(in millions of U.S. dollars) | 2024 |  | 2023
Cash and cash equivalents | $ | 100 |  |  | $ | 98 |
Mutual funds | 5,649 |  |  | 5,382 |
Fixed maturities | 85 |  |  | 94 |
Total | $ | 5,834 |  |  | $ | 5,574 |

The following table presents a roll-forward of separate account liabilities:

| Six Months Ended
| June 30
(in millions of U.S. dollars) | 2024 |  | 2023
Balance – beginning of period | $ | 5,573 |  |  | $ | 5,190 |
Premiums and deposits | 576 |  |  | 517 |
Policy charges | (80) |  |  | (70) |
Surrenders and withdrawals | (426) |  |  | (246) |

Balance – end of period | $ | 5,834 |  |  | $ | 5,574 |
Cash surrender value (1) | $ | 5,625 |  |  | $ | 5,369 |

(1)Cash surrender value represents the amount of the contract holder'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 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:

11. 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:

| Six Months Ended June 30
(in millions of U.S. dollars) | 2024 |  | 2023
Balance – beginning of period | $ | 771 |  |  | $ | 800 |
Balance, beginning of period, before effect of changes in the instrument-specific credit risk | 749 |  |  | 776 |
Interest rate changes | (87) |  |  | 37 |
Effect of changes in equity markets | (83) |  |  | (144) |
Effect of changes in volatilities | (13) |  |  | 31 |
Actual policyholder behavior different from expected behavior | 31 |  |  | 14 |
Effect of timing and all other | (33) |  |  | (8) |
Balance, end of period, before effect of changes in the instrument-specific credit risk | $ | 564 |  |  | $ | 706 |
Effect of changes in the instrument-specific credit risk | 12 |  |  | 16 |
Balance – end of period | $ | 576 |  |  | $ | 722 |
Weighted-average age of policyholders (years) | 74 |  | 73
Net amount at risk (1) | $ | 1,630 |  |  | $ | 2,048 |

(1) 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 gains (losses) of $(191) million and $(192) million for the six months ended June 30, 2024 and 2023, 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.

|  |  | Valuation Technique |  | Significant Unobservable Inputs |  | June 30, 2024 |  | June 30, 2023
|  |  | Ranges |  | Weighted Average(1) |  | Ranges |  | Weighted Average(1)
MRB (1) |  |  | Actuarial model |  | Lapse rate |  | 0.5% – 30.0% |  | 4.3 | % |  | 0.5% – 30.4% |  | 4.0 | %
|  |  |  |  | Annuitization rate |  | 0% – 100% |  | 4.3 | % |  | 0% – 100% |  | 4.2 | %

(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. For treaties with limited experience, rates are established by blending the experience with data received from other ceding companies. 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 2023 Form 10-K.
12. 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 either Fixed maturities available-for-sale (FM AFS) or Equity securities (ES), depending on the underlying investment. These are the most numerous and frequent derivative transactions. 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 of derivative instruments in an asset or (liability) position, and notional value/payment provision of our derivative instruments:

Chubb Limited and Subsidiaries
At June 30, 2024, and December 31, 2023, net derivative liabilities of $103 million and $115 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 for 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) Cross-currency swaps - fair value hedges
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 €1.5 billion, or approximately $1.6 billion at June 30, 2024, of our 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

Interest expense reclassified from OCI | (4) |  | (4) |  |  | (8) |  | (8) |
OCI gain (loss) after reclassifications | $ | (30) |  | $ | 50 |  |  | $ | 3 |  | $ | 17 |

(ii) Cross-currency swaps - net investment hedges
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, and Swiss franc. 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.
The mark-to-market adjustments for foreign currency changes will remain until the underlying hedge subsidiary is deconsolidated or if hedge accounting is discontinued.
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 is reclassified to Interest expense as follows:

| Three Months Ended |  | Six Months Ended
| June 30 |  | June 30

(1)Includes embedded derivatives.
(2)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.
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
37

Table of Contents
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries
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 or preferred stock 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 either available-for-sale or as an equity security. Chubb purchases convertible securities for their total return and not specifically for the conversion feature.
(iv) TBA
By acquiring 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

At June 30, 2024, and December 31, 2023, our repurchase agreement obligations of $3,149 million and $2,833 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:

Gross amount of recognized liabilities for repurchase agreements |  |  |  |  |  |  | $ | 3,149 |  |  |  |  |  |  |  |  | $ | 2,833 |
Difference (1) |  |  |  |  |  |  | $ | 140 |  |  |  |  |  |  |  |  | $ | 91 |

(1)Per the repurchase agreements, the amount of collateral posted is required to exceed the amount of gross liability.
Potential risks exist in our secured borrowing transactions due to market conditions and counterparty exposure. With collateral that we pledge, there is a risk that the collateral may not be returned at the expiration of the agreement. If the counterparty fails to return the collateral, Chubb will have free use of the borrowed funds until our collateral is returned. In addition, we may encounter the risk that Chubb may not be able to renew outstanding borrowings with a new term or with an existing counterparty due to market conditions including a decrease in demand as well as more restrictive terms from banks due to increased regulatory and capital constraints. Should this condition occur, Chubb may seek alternative borrowing sources or reduce borrowings. Additionally, increased margins and collateral requirements due to market conditions would increase our restricted assets as we are required to provide additional collateral to support the transaction.
e) Fixed maturities
At June 30, 2024, and December 31, 2023, commitments to purchase fixed income securities over the next several years were $1.2 billion and $1.0 billion, respectively.
f) Private equities
Private equities in the Consolidated balance sheets are investments in limited partnerships and partially-owned investment companies with a carrying value of $14.1 billion at June 30, 2024. In connection with these investments, we have commitments that may require funding of up to $6.8 billion over the next several years. At December 31, 2023, these investments had a carrying value of $13.9 billion with commitments that could have required funding of up to $6.2 billion.
g) Income taxes
At June 30, 2024, $72 million of unrecognized tax benefits remain out standing. It is reasonably possible that, over the next twelve months, the amount of unrecognized tax benefits may change resulting from the re-evaluation of unrecognized tax benefits arising from examinations by taxing authorities, settlements, and the lapses of statutes of limitations. With few exceptions, Chubb is no longer subject to income tax examinations for years before 2012.
h) 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.
i) Lease commitments
At June 30, 2024, and December 31, 2023, the right-of-use asset was $743 million and $784 million, respectively, recorded within Other assets, and the lease liability was $801 million and $832 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.
13. 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, 2024, our Common Shares had a par value of CHF 0.50 per share.
At our May 2024 annual general meeting, our shareholders approved an annual dividend for the following year of up to $3.64 per share, expected to be paid in four quarterly installments of $0.91 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 2025 annual general meeting, and is authorized to abstain from distributing a dividend at its discretion.
At our May 2023 and 2022 annual general meetings, our shareholders approved annual dividends for the following year of up to $3.44 per share and $3.32 per share, respectively, which were paid in four quarterly installments of $0.86 per share and $0.83 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

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. At our May 2023 annual general meeting, held on May 17, 2023, our shareholders approved the cancellation of 14,925,028 shares purchased under our share repurchase programs during 2022. The capital reduction was subject to publication requirements and became effective in accordance with Swiss law on May 22, 2023. At our May 2024 annual general meeting, held on May 16, 2024, our shareholders approved the cancellation of 11,825,600 shares purchased under our share repurchase programs during 2023. The capital reduction was subject to publication requirements and became effective in accordance with Swiss law on May 21, 2024. During the six months ended June 30, 2024, 3,474,357 shares were repurchased, 11,825,600 shares were canceled, and 2,278,215 net shares were issued under employee share-based compensation plans. At June 30, 2024, 15,552,491 Common Shares remain in treasury.

14. 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 February 26, 2024, Chubb granted 1,359,237 stock options with a weighted-average grant date fair value of $64.15 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 (shareholders' equity less goodwill and intangible assets, 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 February 26, 2024, Chubb granted 685,665 service-based restricted stock, 290,085 service-based restricted stock units, 101,514 performance shares, and 284,013 performance stock units to employees and officers with a grant date fair value of $254.84 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).

percent, and partially-owned insurance companies. This line item includes mark-to-market gains (losses) on private equities of $4 million and $107 million for the three and six months ended June 30, 2024, respectively, and $(3) million and $239 million, respectively, for the prior year periods.
In addition, this line item includes net income attributable to our investment in Huatai under the equity method of accounting comprising income of $22 million and $36 million for the three and six months ended June 30, 2023, respectively. Effective July 1, 2023, we discontinued the equity method of accounting and include the results of operations of Huatai in our consolidated results.
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.
17. Segment information
Chubb operates through six business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insuran ce, 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 intermediar ies. Effective July 1, 2023, the results of Huatai's life and asset management businesses, included within the Life Insurance segment, and the results of Huatai's P&C insurance business, included within Overseas General Insurance, are presented gross within Underwriting income (loss), Net investment income (loss), and Other income (expense) as required under consolidation accounting. Huatai's results prior to July 1, 2023 were included net within Other (income) expense based on our ownership interest as required under equity method accounting.
Management uses Underwriting income (loss) as the 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. Segment income (loss) includes Underwriting income (loss), Net investment income (loss), 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. Our main measure of segment performance is Segment income (loss), which also includes Amortization of purchased intangibles acquired by the segment. 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, Cigna integration expenses, Income tax expense, and Net income (loss) attributable to noncontrolling interests are reported within Corporate. Cigna integration expenses are one-time costs that are directly attributable to third-party consulting fees, employee-related retention costs, and other professional and legal fees primarily related to the acquisition of Cigna's business in Asia. 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 Chief Executive Officer does not manage segment results or allocate resources to segments when considering these costs, and therefore 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. These items are reconciled to the consolidated presentation in the Segment measure reclass column below and include:
•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. We view gains and losses from fair value changes in both separate account assets and liabilities as part of the results of our underwriting operations, and therefore these gains and losses are reclassified 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 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.

Financial Highlights for the Three Months Ended June 30, 2024
•Net income attributable to Chubb was $2.2 billion compared with $1.8 billion in the prior year period. Net income in the current quarter was driven by strong underwriting results and record net investment income.
•Consolidated net premiums written were $13.4 billion, up 11.8 percent, or 12.3 percent in constant dollars. P&C net premiums written increased 10.3 percent, or 10.6 percent in constant dollars, with commercial insurance up 8.8 percent and consumer insurance up 15.9 percent. Life Insurance segment net premiums written increased 24.5 percent, or 27.6 percent in constant dollars, reflecting the impact of the consolidation of Huatai Group on July 1, 2023, and growth in existing business.
•Pre-tax net investment income was a record $1.5 billion compared with $1.1 billion in the prior year period, primarily due to strong operating cash flow at higher reinvestment rates on fixed maturities, and the consolidation of Huatai Group.
•Consolidated net premiums earned were $12.3 billion, up 11.7 percent, or 12.3 percent in constant dollars.
•Total pre-tax and after-tax catastrophe losses, net of reinsurance and including reinstatement premiums, were $580 million (5.4 percentage points of the P&C combined ratio) and $482 million, respectively, compared with $400 million (4.1
54

percentage points of the P&C combined ratio) and $319 million, respectively, in the prior year period.
•Total pre-tax and after-tax favorable prior period development were $192 million and $167 million, respectively, compared with $200 million and $155 million, respectively, in the prior year period.
•The P&C combined ratio was 86.8 percent compared with 85.4 percent in the prior year period. The current year ratio increased primarily due to higher catastrophe losses and lower favorable prior period development. The P&C current accident year (CAY) combined ratio excluding catastrophe losses was 83.2 percent compared with 83.3 percent in the prior year period.
•Operating cash flow was $4.1 billion compared with $2.5 billion in the prior year period.
•Chubb shareholders' equity increased $503 million in the quarter, primarily from net income attributable to Chubb of $2.2 billion, partially offset by total capital returned to shareholders of $939 million, net unrealized losses of $478 million related to cumulative foreign exchange translation, and net unrealized losses on our investment portfolio of $476 million, reflecting the mark-to-market impact in the fixed-income portfolio. Total capital returned to shareholders comprises share repurchases of $570 million at an average purchase price of $253.02 per share, and dividends of $369 million.

(1)Commercial multiple peril represents retail package business (property and general liability).
The increase in consolidated net premiums written for the three and six months ended June 30, 2024, reflects growth across most product lines driven by strong premium retention, including rate and exposure increases, and strong new business. The consolidation of Huatai Group's life and P&C businesses contributed $445 million, or 3.6 percentage points, and $1,004 million, or 4.2 percentage points, for the three and six months ended June 30, 2024, respectively.

•Property and other short-tail lines grew globally due to strong new business and retention, including both rate and exposure increases.
•Commercial casualty grew globally due to strong retention, including both rate and exposure increases, and strong new business.
•Financial lines declined due to a competitive market environment and lower retention.
•Workers' compensation grew slightly due to new business and retention, including exposure increases.
•Commercial multiple peril grew due to strong new business and retention, including higher rates in North America.
•Surety grew due to strong new business.
•Agriculture declined primarily due to lower commodity prices in the current year. The decrease in net premiums written for the six months ended June 30, 2024, also reflects a return of premium under the U.S. government risk-sharing formula related to the 2023 crop year.
•Personal lines grew globally due to new business and renewal retention, as well as increases in both rate and exposure, and the consolidation of Huatai.
•Global A&H – P&C grew in Europe and Asia, with Asia partially benefiting from the consolidation of Huatai.
•Reinsurance lines reflected continued growth, mainly in property lines and a large one-off structured transaction in the three months ended June 30, 2024.
•Life Insurance grew due to the consolidation of Huatai Group, and organic growth in Asia, Latin America, and in Combined Insurance North America. The consolidation of Huatai Group contributed $219 million, or 17.3 percentage points, and $485 million, or 18.9 percentage points, to growth for the three and six months ended June 30, 2024, respectively.

Table of Contents
Net Premiums Earned
Net premiums earned for short-duration contracts, typically P&C contracts, generally reflect the portion of net premiums written that was recorded as revenues for the period as the exposure periods expire. Net premiums earned for long-duration contracts, typically traditional life contracts, generally are recognized as earned when due from policyholders. For the three months ended June 30, 2024, net premiums earned increased $1.3 billion, up 11.7 percent, or 12.3 percent in constant dollars. P&C net premiums earned increased 10.1 percent, or 10.4 percent in constant dollars, comprising growth in commercial insurance and consumer insurance of 8.8 percent and 15.1 percent, respectively. For the six months ended June 30, 2024, net premiums earned increased $2.7 billion, up 12.9 percent, or 13.4 percent in constant dollars. P&C net premiums earned increased 11.1 percent, or 11.3 percent in constant dollars, comprising growth in commercial insurance and consumer insurance of 10.1 percent and 14.6 percent, respectively.
Catastrophe Losses and Prior Period Development
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 losses are net of reinsurance and include reinstatement premiums, which are additional premiums paid on certain reinsurance agreements in order to reinstate coverage that had been exhausted by loss occurrences. The reinstatement premium amount is typically a pro rata portion of the original ceded premium paid based on how much of the reinsurance limit had been exhausted.
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. PPD includes adjustments relating to either profit commission reserves or policyholder dividend reserves based on actual claim experience that develops after the policy period ends. The expense adjustments correlate to the prior period loss development on these same policies. Refer to the Non-GAAP Reconciliation section for further information on reinstatement premiums on catastrophe losses and adjustments to prior period development.

Catastrophe losses through June 30, 2024 and 2023, were primarily from the following events:
•2024: Severe weather-related events in the U.S. and internationally, including Rio Grande storms.
•2023: Severe weather-related events in the U.S. and internationally, including New Zealand storms.
Pre-tax net favorable PPD for the three months ended June 30, 2024, was $285 million in our active companies with 35 percent in long-tail lines, primarily in workers' compensation lines, partially offset by unfavorable development in commercial auto liability, and 65 percent in short-tail lines, primarily in marine and property lines. Our corporate run-off portfolio had adverse development of $93 million, which included molestation-related claims development of approximately $60 million.
Pre-tax net favorable PPD for the six months ended June 30, 2024, was $501 million in our active companies, principally in short-tail property and marine lines. Our corporate run-off portfolio had adverse development of $102 million, primarily for molestation-related claims development.
Pre-tax net favorable PPD for the three months ended June 30, 2023, was $200 million, including adverse development of $49 million for molestation-related claims development.
Pre-tax net favorable PPD for the six months ended June 30, 2023, was $396 million, including adverse development of $49 million for molestation claims. Excluding the adverse development, we had net favorable development of $445 million with 23 percent in long-tail lines, principally from accident years 2011 through 2019, and 77 percent in short-tail lines, primarily in A&H and surety lines.

P&C Combined Ratio
In evaluating our segments, excluding Life Insurance financial performance, we use the P&C combined ratio, the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. We calculate these ratios by dividing the respective expense amounts by net premiums earned. We do not calculate these ratios for the Life Insurance segment as we do not use these measures to monitor or manage the business in that segment. The P&C combined ratio is determined by adding the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. A P&C combined ratio under 100 percent indicates underwriting income, and a combined ratio exceeding 100 percent indicates underwriting loss.

| Three Months Ended |  | Six Months Ended
| June 30 |  | June 30
| 2024 |  | 2023 |  | 2024 |  | 2023
Combined ratio: |  |  |  |  |  |  |
Loss and loss expense ratio | 60.6 | % |  | 59.3 | % |  | 59.4 | % |  | 59.1 | %
Policy acquisition cost ratio | 18.0 | % |  | 17.9 | % |  | 18.6 | % |  | 18.3 | %
Administrative expense ratio | 8.2 | % |  | 8.2 | % |  | 8.4 | % |  | 8.4 | %
P&C Combined ratio | 86.8 | % |  | 85.4 | % |  | 86.4 | % |  | 85.8 | %
Catastrophe losses | (5.4) | % |  | (4.1) | % |  | (4.9) | % |  | (4.6) | %
Prior period development | 1.8 | % |  | 2.0 | % |  | 1.9 | % |  | 2.2 | %
P&C CAY combined ratio excluding catastrophe losses | 83.2 | % |  | 83.3 | % |  | 83.4 | % |  | 83.4 | %

The P&C combined ratio increased for the three and six months ended June 30, 2024, reflecting higher catastrophe losses and a lower impact from favorable prior period development.
The P&C CAY combined ratio excluding catastrophe losses was relatively flat for the three and six months ended June 30, 2024, primarily reflecting the favorable impact of higher net premiums earned and a higher percentage of net premiums earned from property lines and homeowners. These factors were substantially offset by higher loss trends in certain casualty lines, price changes not keeping pace with loss trends in financial lines, and increased spending to support growth.
Policy benefits
Policy benefits represent losses on contracts classified as long-duration and generally include accident and supplemental health products, term and whole life products, endowment products, and annuities. Policy benefits include (gains) losses from fair value changes in separate account liabilities that do not qualify for separate account treatment under U.S. GAAP. The offsetting movements of these liabilities are recorded in Other (income) expense in the Consolidated statements of operations. In addition, Policy benefits include the impact on the liabilities from (gains) losses on investment portfolios supporting certain participating policies. The offsetting movements of these liabilities are recorded in Realized gains (losses) in the Consolidated statements of operations. Policy benefits for the three and six months ended June 30, 2024, include the results of Huatai Group. Refer to the Life Insurance segment operating results section for further discussion.
Policy benefits were $1,219 million and $830 million for the three months ended June 30, 2024 and 2023, respectively, and $2,399 million and $1,627 million for the six months ended June 30, 2024 and 2023, respectively. The increase in Policy benefits is primarily due to the consolidation of Huatai Group.

Premiums
Net premiums written decreased $9 million, or 1.2 percent, and $53 million, or 5.0 percent, for the three and six months ended June 30, 2024, primarily due lower commodity prices in the current year. The decrease in net premiums written for the six months ended June 30, 2024, also reflects a return of premium of $41 million under the U.S. government risk-sharing formula related to the 2023 crop year. Under the profit-sharing agreement, we ceded more premium due to lower losses experienced in certain states. The decrease was partially offset by strong new business and rate increases in our Agriculture P&C business.

Premiums
Net premiums written increased $118 million and $200 million for the three and six months ended June 30, 2024, respectively, primarily reflecting continued growth driven by strong new business. The increase in premium was most notably in property and casualty lines, which included a large one-off structured transaction in the current quarter. This transaction benefited growth by 12.5 and 6.5 percentage points for the three and six months ended June 30, 2024, respectively.
Net premiums earned increased $102 million and $153 million for the three and six months ended June 30, 2024, respectively, reflecting the increase in net premiums written described above, including the large structured transaction, which was fully earned when written.

Combined Ratio
The combined ratio increased for the three and six months ended June 30, 2024, primarily reflecting the impact of lower favorable prior period development, as a percentage of net premiums earned. The CAY combined ratio excluding catastrophe losses increased for the three months ended June 30, 2024, primarily due to the impact of the large structured transaction, partially offset by growth in property lines, resulting in a lower expected loss ratio. The CAY combined ratio excluding catastrophe losses improved for the six months ended June 30, 2024, primarily due to favorable market conditions in catastrophe exposed property lines and favorable impact of higher net premiums earned on the administrative expense ratio, partially offset by the impact of the large structured transaction described above.
Life Insurance
The Life Insurance segment comprises our international life operations. Effective July 1, 2023, the Life Insurance segment includes 100 percent of the results of Huatai Group's life and asset management business as required under consolidation accounting. We previously included our share of Huatai results based on our equity method investment within Other (income) expense. The Life Insurance segment also includes Chubb Tempest Life Re (Chubb Life Re), and the North American supplemental A&H and life business of Combined Insurance.

Premiums
Net premiums written increased $310 million and $650 million, or $342 million and $716 million on a constant-dollar basis, for the three and six months ended June 30, 2024, respectively.
For our international life operations, net premiums written increased 27.8 percent and 29.6 percent for the three and six months ended June 30, 2024, substantially due to the consolidation of Huatai Group's life business which contributed $219 million and $485 million or 21.3 and 23.4 percentage points, respectively. The remaining increase in net premiums written is primarily driven by growth in North and Southeast Asia as well as by higher new business in Latin America.
Net premiums written in our North American Combined Insurance business increased 11.8 percent and 8.6 percent, for the three and six months ended June 30, 2024, respectively, due to growth in its worksite business of 28.7 percent and 24.6 percent partially offset by the non-renewal of a large program.

Deposits collected on universal life and investment contracts (life deposits) are not reflected as revenues in our Consolidated statements of operations in accordance with U.S. GAAP. New life deposits are an important component of production, and although they do not significantly affect current period income from operations, they are key to our efforts to grow our business. Life deposits collected increased $147 million and $438 million for the three and six months ended June 30, 2024, respectively, primarily from the consolidation of Huatai Life business.
Life Insurance segment income
Life Insurance segment income increased $22 million and $46 million for the three and six months ended June 30, 2024, reflecting the growth in premiums described above, as well as higher net investment income from fund investments and fixed income yield.
Corporate
Corporate results primarily include the results of our non-insurance companies, income and expenses not attributable to reportable segments, and loss and loss expenses of asbestos and environmental (A&E) liabilities and certain other non-A&E run-off exposures, including molestation. Effective July 1, 2023, 100 percent of Huatai Group’s non-insurance operations results, comprising real estate and holding company activity, are included in Corporate.

Cigna integration expenses principally comprised legal and professional fees and all other costs directly related to the integration activities of the Cigna acquisition. These expenses are one-time in nature and are not related to the on-going business activities of the segments. The Chief Executive Officer does not manage segment results or allocate resources to segments when considering these costs and they are therefore excluded from our definition of segment income.
Refer to the respective sections that follow for a discussion of Net realized gains (losses), Net investment income (loss), Amortization of purchased intangibles, and Income tax expense (benefit). Refer to Notes 11 and 16 to the Consolidated Financial Statements for additional information on Market risk benefits gains (losses) and Other (income) expense, respectively.

Net Realized and Unrealized Gains (Losses)

We take a long-term view with our investment strategy, and our investment managers manage our investment portfolio to maximize total return within specific guidelines designed to minimize risk. The majority of our investment portfolio is available-for-sale and reported at fair value.
The effect of market movements on our fixed maturities available-for-sale portfolio impacts Net income (through Net realized gains (losses)) when securities are sold, when we write down an asset, or when we record a change to the valuation allowance for expected credit losses. For a further discussion related to how we assess the valuation allowance for expected credit losses and the related impact on Net income, refer to Note 1 f) to the Consolidated Financial Statements in our 2023 Form 10-K. The effect of market movements on fixed maturities related to consolidated investment products and investments supporting certain participating products in the Huatai portfolio impact Net realized gains (losses). Additionally, Net income is impacted through the reporting of changes in the fair value of public and private equity securities and derivatives, including financial futures, options, and swaps. Changes in unrealized appreciation and depreciation on available-for-sale securities, resulting from the revaluation of securities held, changes in cumulative foreign currency translation adjustment, changes in current discount rate on future policy benefits, changes in instrument-specific credit risk on market risk benefits, unrealized postretirement benefit obligations liability adjustment, and cross-currency swaps designated as hedges for accounting purposes are reported as separate components of Accumulated other comprehensive income (loss) in Shareholders’ equity in the Consolidated balance sheets.

Pre-tax net unrealized losses of $489 million and $1,166 million in our investment portfolio for the three and six months ended June 30, 2024, respectively, were primarily driven by higher interest rates.

Effective Income Tax Rate

Our effective tax rate (ETR) reflects a mix of income or losses in jurisdictions with a wide range of tax rates, permanent differences between U.S. GAAP and local tax laws, and the impact of discrete items. A change in the geographic mix of earnings could impact our ETR.
For the three and six months ended June 30, 2024, our ETR was 18.1 percent and 15.6 percent, respectively, compared to an ETR of 17.9 percent and 17.4 percent, respectively, in the prior year. The ETR for each period was impacted by our mix of earnings among various jurisdictions and by discrete tax items. The six months ended June 30, 2024 included an incremental deferred tax benefit of $55 million in the first quarter related to the Bermuda tax law enacted in December 2023.

Non-GAAP Reconciliation

In presenting our results, we included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important for an understanding of our overall results of operations and financial condition. However, they should not be viewed as a substitute for measures determined in accordance with GAAP.
We provide financial measures, including net premiums written, net premiums earned, and underwriting income on a constant-dollar basis. We believe it is useful to evaluate the trends in our results exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which our international business is transacted, as these exchange rates could fluctuate significantly between periods and distort the analysis of trends. The impact is determined by assuming constant foreign exchange rates between periods by translating prior period results using the same local currency exchange rates as the comparable current period.
P&C performance metrics comprise consolidated operating results (including Corporate) and exclude the operating results of the Life Insurance segment. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’s P&C operations which are the most economically similar. We exclude the Life Insurance segment because the results of this business do not always correlate with the results of our P&C operations.

Table of Contents
P&C combined ratio is the sum of the loss and loss expense ratio, policy acquisition cost ratio and the administrative expense ratio excluding the life business and including the realized gains and losses on the 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.
CAY P&C combined ratio excluding catastrophe losses (CATs) excludes CATs and prior period development (PPD) from the P&C combined ratio. We exclude CATs as they are not predictable as to timing and amount and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. The combined ratio numerator is adjusted to exclude CATs, PPD, and expense adjustments on PPD, and the denominator is adjusted to exclude net premiums earned adjustments on PPD and reinstatement premiums on CATs and PPD. In periods where there are adjustments on loss sensitive policies, these adjustments are excluded from PPD and net premiums earned when calculating the ratios. We believe this measure provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our P&C business that may be obscured by these items. This measure is commonly reported among our peer companies and allows for a better comparison.
Reinstatement premiums are additional premiums paid on certain reinsurance agreements in order to reinstate coverage that had been exhausted by loss occurrences. The reinstatement premium amount is typically a pro rata portion of the original ceded premium paid based on how much of the reinsurance limit had been exhausted.
Net premiums earned adjustments within PPD are adjustments to the initial premium earned on retrospectively rated policies based on actual claim experience that develops after the policy period ends. The premium adjustments correlate to the prior period loss development on these same policies and are fully earned in the period the adjustments are recorded.
Prior period expense adjustments typically relate to adjustable commission reserves or policyholder dividend reserves based on actual claim experience that develops after the policy period ends. The expense adjustments correlate to the prior period loss development on these same policies.

Net investment income is influenced by a number of factors including the amounts and timing of inward and outward cash flows, the level of interest rates, and changes in overall asset allocation. Net investment income increased 28.2 percent and 27.0 percent for the three and six months ended June 30, 2024, respectively, primarily due to higher reinvestment rates on fixed maturities and the consolidation of Huatai Group.
For private equities where we own less than three percent, investment income is included within Net investment income in the table above. For private equities where we own more than three percent, investment income is included within Other (income) expense in the Consolidated statements of operations. Excluded from Net investment income is the mark-to-market movement for private equities, which is recorded within either Other (income) expense or Net realized gains (losses) based on our percentage of ownership. The total mark-to-market movement for private equities excluded from Net investment income was as follows:

Investments

Our investment portfolio is invested primarily in publicly traded, investment grade, fixed income securities with an average credit quality of A/A as rated by the independent investment rating services Standard and Poor’s (S&P)/Moody’s Investors Service (Moody’s) at June 30, 2024. Excluding Huatai, the portfolio is primarily managed externally by independent, professional investment managers and is broadly diversified across geographies, sectors, and issuers. We hold no collateralized debt obligations in our investment portfolio, and we provide no credit default protection. We have long-standing global credit limits for our entire portfolio across the organization. Exposures are aggregated, monitored, and actively managed by our Global Credit Committee, comprising senior executives, including our Chief Financial Officer, our Chief Risk Officer, our Chief Investment Officer, and our Treasurer. We also have well-established, strict contractual investment rules requiring managers to maintain highly diversified exposures to individual issuers and clos ely monitor investment manager compliance with portfolio guidelines.

Municipal
As part of our overall investment strategy, we may invest in states, municipalities, and other political subdivisions fixed maturity securities (Municipal). We apply the same investment selection process described previously to our Municipal investments. The portfolio is highly diversified primarily in state general obligation bonds and essential service revenue bonds including education and utilities (water, power, and sewers).
Non-U.S.
Chubb’s local currency investment portfolios have strict contractual investment guidelines requiring managers to maintain a high quality and diversified portfolio to both sector and individual issuers. Investment portfolios are monitored daily to ensure investment manager compliance with portfolio guidelines.
Our non-U.S. investment grade fixed income portfolios are currency-matched with the insurance liabilities of our non-U.S. operations. The average credit quality of our non-U.S. fixed income securities is A and 39 percent of our holdings are rated AAA or guaranteed by governments or quasi-government agencies. Within the context of these investment portfolios, our government and corporate bond holdings are highly diversified across industries and geographies. Issuer limits are based on credit rating (AA—two percent, A—one percent, BBB—0.5 percent of the total portfolio) and are monitored daily via an internal compliance system. We manage our indirect exposure using the same credit rating-based investment approach. Accordingly, we do not believe our indirect exposure is material.

Below-investment grade corporate fixed income portfolio
Below-investment grade securities have different characteristics than investment grade corporate debt securities. Risk of loss from default by the borrower is greater with below-investment grade securities. Below-investment grade securities are generally unsecured and are often subordinated to other creditors of the issuer. Also, issuers of below-investment grade securities usually have higher levels of debt and are more sensitive to adverse economic conditions, such as recession or increasing interest rates, than investment grade issuers. At June 30, 2024, our corporate fixed income investment portfolio included below-investment grade and non-rated securities which, in total, comprised approximately 14 percent of our fixed income portfolio. Our below-investment grade and non-rated portfolio includes over 1,600 issuers, with the greatest single exposure being $167 million.
We manage high-yield bonds as a distinct and separate asset class from investment grade bonds. The allocation to high-yield bonds is explicitly set by internal management and is targeted to securities in the upper tier of credit quality (BB/B). Our minimum rating for initial purchase is BB/B. Fifteen external investment managers are responsible for high-yield security selection and portfolio construction. Our high-yield managers have a conservative approach to credit selection and very low historical default experience. Holdings are highly diversified across industries and generally subject to a 1.5 percent issuer limit

as a percentage of high-yield allocation. We monitor position limits daily through an internal compliance system. Derivative and structured securities (e.g., credit default swaps and collateralized debt obligations) are not permitted in the high-yield portfolio.

Critical Accounting Estimates

Unpaid losses and loss expenses
As an insurance and reinsurance company, we are required by applicable laws and regulations and U.S. GAAP to establish loss and loss expense reserves for the estimated unpaid portion of the ultimate liability for losses and loss expenses under the terms of our policies and agreements with our insured and reinsured customers. With the exception of certain structured settlements, for which the timing and amount of future claim payments are reliably determinable, and certain reserves for unsettled claims, our loss reserves are not discounted for the time value of money.
The following table presents a roll-forward of our unpaid losses and loss expenses:

(in millions of U.S. dollars) | Gross Losses |  | Reinsurance Recoverable (1) |  | Net Losses
Balance at December 31, 2023 | $ | 80,122 |  |  | $ | 17,884 |  |  | $ | 62,238 |
Losses and loss expenses incurred | 14,422 |  |  | 2,264 |  |  | 12,158 |
Losses and loss expenses paid | (12,080) |  |  | (2,670) |  |  | (9,410) |
Other (including foreign exchange translation) | (273) |  |  | (69) |  |  | (204) |
Balance at June 30, 2024 | $ | 82,191 |  |  | $ | 17,409 |  |  | $ | 64,782 |

(1)Net of valuation allowance for uncollectible reinsurance.
The estimate of the liabilities includes provisions for claims that have been reported but are unpaid at the balance sheet date (case reserves) and for obligations on claims that have been incurred but not reported (IBNR) at the balance sheet date. IBNR may also include provisions to account for the possibility that reported claims may settle for amounts that differ from the established case reserves. Loss reserves also include an estimate of expenses associated with processing and settling unpaid claims (loss expenses).
Refer to Note 8 to the Consolidated Financial Statements for a discussion on the changes in the loss reserves.
Asbestos and Environmental (A&E)
There was no significant A&E reserve activity during the three and six months ended June 30, 2024. A&E reserves are included in Corporate. Refer to our 2023 Form 10-K for further information on our A&E exposures.
Fair value measurements
Accounting 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 (Level 1 inputs) and the lowest priority to unobservable data (Level 3 inputs). Level 2 includes inputs, other than quoted prices within Level 1, that are observable for assets or liabilities either directly or indirectly. Refer to Note 4 to the Consolidated Financial Statements for information on our fair value measurements.

Catastrophe Management

We actively monitor and manage our catastrophe risk accumulation around the world from natural perils, which includes setting risk limits based on probable maximum loss (PML) and purchasing catastrophe reinsurance to ensure sufficient liquidity and capital to meet the expectations of regulators, rating agencies, and policyholders, and to provide shareholders with an appropriate risk-adjusted return. Chubb uses internal and external data together with sophisticated, analytical catastrophe loss and risk modeling techniques to ensure an appropriate understanding of risk, including diversification and correlation effects, across different product lines and territories. The table below presents our modeled pre-tax estimates of natural catastrophe PML, net of reinsurance, at June 30, 2024, and does not represent our expected catastrophe losses for any one year.

| Modeled Net Probable Maximum Loss (PML) Pre-tax
| Worldwide (1) |  | U.S. Hurricane (2) |  | California Earthquake (3)
| Annual Aggregate |  | Annual Aggregate |  | Single Occurrence
(in millions of U.S. dollars, except for percentages) | Chubb |  | % of Total Chubb Shareholders’ Equity |  | Chubb |  | % of Total Chubb Shareholders’ Equity |  | Chubb |  | % of Total Chubb Shareholders’ Equity

1-in-250 | $ | 8,180 |  |  | 13.4 | % |  | $ | 5,718 |  |  | 9.4 | % |  | $ | 2,157 |  |  | 3.5 | %

(1) Worldwide aggregate includes modeled losses arising from tropical cyclones, convective storms, earthquakes, wildfires, and inland floods, and excludes "non-modeled" perils such as man-made and other catastrophe risks including pandemic.
(2) U.S. hurricane modeled losses include losses from wind, storm-surge, and related precipitation-induced flooding.
(3) California earthquake modeled losses include the fire-following sub-peril.
The PML for worldwide and key U.S. peril regions are based on our in-force portfolio at April 1, 2024, and reflect the April 1, 2024, reinsurance program, as well as inuring reinsurance protection coverage. As of April 1, 2024, we increased retention in North America by $500 million and increased limits by $1.7 billion. Refer to the Global Property Catastrophe Reinsurance section for more information. These estimates assume that reinsurance recoverable is fully collectible.
According to the model, for the 1-in-100 return period scenario, there is a one percent chance that our pre-tax annual aggregate losses incurred in any year from U.S. hurricane events could be in excess of $3,636 million (or 6.0 percent of total Chubb shareholders’ equity at June 30, 2024). Effective March 31, 2024, our worldwide and U.S. Hurricane PMLs reflect the latest North Atlantic hurricane vulnerability model.
The above estimates of Chubb’s loss profile are inherently uncertain for many reasons, including the following:
•While the use of third-party modeling packages to simulate potential catastrophe losses is prevalent within the insurance industry, the models are reliant upon significant meteorology, seismology, and engineering assumptions to estimate catastrophe losses. In particular, modeled catastrophe events are not always a representation of actual events and ensuing additional loss potential;
•There is no universal standard in the preparation of insured data for use in the models, the running of the modeling software, and interpretation of loss output. These loss estimates do not represent our potential maximum exposures and it is highly likely that our actual incurred losses would vary materially from the modeled estimates;
•The potential effects of climate change add to modeling complexity; and
•Changing climate conditions could impact our exposure to natural catastrophe risks. Published studies by leading government, academic, and professional organizations combined with extensive research by Chubb climate scientists reveal the potential for increases in the frequency and severity of key natural perils such as tropical cyclones, inland flood, and wildfire. To understand the potential impacts on the Chubb portfolio, we have conducted stress tests on our peak exposure zone, namely in the U.S., using parameters outlined by the Intergovernmental Panel on Climate Change (IPCC) Climate Change 2021 report. These parameters consider the impacts of climate change and the resulting climate peril impacts over a timescale relevant to our business. The tests are conducted by adjusting our baseline view of risk for the perils of hurricane, inland flood, and wildfire in the U.S. to reflect increases in frequency and severity across the modeled domains for each of these perils. Based on these tests against the Chubb portfolio we do not expect material impacts to our baseline PMLs from climate change through December 31, 2024. These tests reflect current exposures only and exclude potentially mitigating factors such as changes to building codes, public or private risk mitigation, regulation, and public policy.
Refer to Item 7 in our 2023 Form 10-K for more information on man-made and other catastrophes.

Chubb’s core property catastrophe reinsurance program provides protection against natural catastrophes impacting its primary property operations (i.e., excluding our Global Reinsurance and Life Insurance segments).
We regularly review our reinsurance protection and corresponding property catastrophe exposures. This may or may not lead to the purchase of additional reinsurance prior to a program’s renewal date. In addition, prior to each renewal date, we consider how much, if any, coverage we intend to buy and we may make material changes to the current structure in light of various factors, including modeled PML assessment at various return periods, reinsurance pricing, our risk tolerance and exposures, and various other structuring considerations.
Chubb renewed its Global Property Catastrophe Reinsurance Program for our North American and International operations effective April 1, 2024, through March 31, 2025. The program consists of three layers in excess of losses retained by Chubb on a per occurrence basis. Chubb renewed its terrorism coverage (excluding nuclear, biological, chemical and radiation coverage, with an inclusion of coverage for biological and chemical coverage for personal lines) for the United States from April 1, 2024, through March 31, 2025, with the same limits and retention and percentage placed except that the majority of terrorism coverage is on an aggregate basis above our retentions without a reinstatement.
Effective September 1, 2023, Chubb purchased an additional layer of per occurrence coverage for named windstorms and earthquakes within Northeast states. Coverage is provided for losses for North American and international operations within the territory through August 31, 2024.

Loss Location |  | Layer of Loss |  | Comments | Notes
United States (excluding Alaska and Hawaii) |  | $0 million – $1.75 billion |  | Losses retained by Chubb | (a)
United States (excluding Alaska and Hawaii) |  | $1.75 billion – $2.85 billion |  | All natural perils and terrorism | (b)
United States (excluding Alaska and Hawaii) |  | $2.85 billion – $4.0 billion |  | All natural perils and terrorism | (c)
United States (excluding Alaska and Hawaii) |  | $4.0 billion – $5.7 billion |  | Named windstorm and earthquake |
United States (Northeast States Only) |  | $3.5 billion – $4.0 billion |  | Named windstorm and earthquake | (d)
International (including Alaska and Hawaii) |  | $0 million – $225 million |  | Losses retained by Chubb | (a)
International (including Alaska and Hawaii) |  | $225 million – $1.325 billion |  | All natural perils and terrorism | (b)
Alaska, Hawaii, and Canada |  | $1.325 billion – $2.475 billion |  | All natural perils and terrorism | (c)

(a) Ultimate retention will depend upon the nature of the loss and the interplay between the underlying per risk programs and certain other catastrophe programs purchased by individual business units. These other catastrophe programs have the potential to reduce our effective retention below the stated levels.
(b) These coverages are both part of the same First layer within the Global Property Catastrophe Reinsurance Program and are fully placed with Reinsurers.
(c) These coverages are both part of the same Second layer within the Global Property C atastrophe Reinsurance Program and are fully placed with Reinsurers.
(d) Northeast states are defined as Virginia to Maine. This coverage is fully placed with Reinsurers and inures to the benefit of the United States (excluding Alaska and Hawaii) layer.

Repurchase agreements are excluded from the table above and are disclosed separately from short-term debt in the Consolidated balance sheets. The repurchase agreements are collateralized borrowings where we maintain the right and ability to redeem the collateral on short notice, unlike short-term debt which comprises the current maturities of our long-term debt instruments.
On March 7, 2024, Chubb INA Holdings LLC (Chubb INA) issued $1.0 billion of 5.0 percent senior notes due March 2034. Chubb INA's $700 million of 3.35 percent senior notes due May 2024 was paid upon maturity.
For the six months ended June 30, 2024, we repurchased $886 million of Common Shares in a series of open market transactions under the Board of Directors (Board) share repurchase authorization. At June 30, 2024, there were 15,552,491 Common Shares in treasury with a weighted-average cost of $159.49 per share, and $2.8 billion in share repurchase authorization remained. For the period July 1, 2024, through July 25, 2024, we repurchased 175,465 Common Shares for a total of $45 million in a series of open market transactions under the share repurchase authorization. At July 25, 2024, $2.8 billion in share repurchase authorization remained.
We generally maintain the ability to issue certain classes of debt and equity securities via a Securities and Exchange Commission (SEC) shelf registration statement which is renewed every three years. This allows us capital market access for refinancing as well as for unforeseen or opportunistic capital needs.
Dividends
We have paid dividends each quarter since we became a public company in 1993. Under Swiss law, dividends must be stated in Swiss francs though dividend payments are made by Chubb in U.S. dollars. Refer to Note 13 to the Consolidated Financial Statements for a discussion of our dividend methodology.
At our May 2024 annual general meeting, our shareholders approved an annual dividend for the following year of up to $3.64 per share, or CHF 3.29 per share, calculated using the USD/CHF exchange rate as published in the Wall Street Journal on May 16, 2024, expected to be paid in four quarterly installments of $0.91 per share after the general meeting by way of a distribution from capital contribution reserves, transferred to free reserves for payment. The Board determines the record and payment dates at which the annual dividend may be paid until the date of the 2025 annual general meeting, and is authorized to abstain from distributing a dividend at its discretion. The annual dividend approved in May 2024 represented a $0.20 per share increase ($0.05 per quarter) over the prior year dividend.
The following table represents dividends paid per Common Share to shareholders of record on each of the following dates:

Shareholders of record as of: |  | Dividends paid as of: |  |  |
December 15, 2023 |  | January 5, 2024 |  | $0.86 (CHF 0.76) |
March 15, 2024 |  | April 5, 2024 |  | $0.86 (CHF 0.75) |
June 14, 2024 |  | July 5, 2024 |  | $0.91 (CHF 0.82) |

Liquidity

We anticipate that positive cash flows from operations (underwriting activities and investment income) should be sufficient to cover cash outflows under most loss scenarios for the near term. In addition to cash from operations, routine sales of investments, and financing arrangements, we have agreements with a third-party bank provider which implemented two international multi-currency notional cash pooling programs to enhance cash management efficiency during periods of short-term timing mismatches between expected inflows and outflows of cash by currency. The programs allow us to optimize investment income by avoiding portfolio disruption. Should the need arise, we generally have access to capital markets and to credit facilities with letter of credit capacity of $4.0 billion, $3.0 billion of which can be used for revolving credit. At June 30, 2024, our usage under these facilities was $903 million in letters of credit. Our access to credit under these facilities is dependent on the ability of the banks that are a party to the facilities to meet their funding commitments. The facilities require that we maintain certain financial covenants, all of which we met at June 30, 2024. Should the existing credit providers on these facilities experience financial difficulty, we may be required to replace credit sources, possibly in a difficult market. If we cannot obtain adequate capital or sources of credit on favorable terms, on a timely basis, or at all, our business, operating results, and financial condition could be adversely affected. To date, we have not experienced difficulty accessing our credit facility or establishing additional facilities when needed.
The payment of dividends or other statutorily permissible distributions from our operating companies are subject to the laws and regulations applicable to each jurisdiction, as well as the need to maintain capital levels adequate to support the insurance and reinsurance operations, including financial strength ratings issued by independent rating agencies. During the six months ended June 30, 2024, we were able to meet all our obligations, including the payments of dividends on our Common Shares, with our net cash flows.
We assess which subsidiaries to draw dividends from based on a number of factors. Considerations such as regulatory and legal restrictions as well as the subsidiary’s financial condition are paramount to the dividend decision. Chubb Limited received dividends of $700 million and $925 million from its Bermuda subsidiaries during the six months ended June 30, 2024 and 2023, respectively. Chubb Limited also received dividends of $91 million from its other international subsidiary during the six months ended June 30, 2024.
The U.S. insurance subsidiaries of Chubb INA may pay dividends, without prior regulatory approval, subject to restrictions set out in state law of the subsidiary’s domicile (or, if applicable, commercial domicile). Chubb INA’s international subsidiaries are also subject to insurance laws and regulations particular to the countries in which the subsidiaries operate. These laws and regulations sometimes include restrictions that limit the amount of dividends payable without prior approval of regulatory insurance authorities. Chubb Limited received no dividends from Chubb INA during the six months ended June 30, 2024 and 2023. Debt issued by Chubb INA is serviced by statutorily permissible distributions by Chubb INA’s insurance subsidiaries to Chubb INA as well as other group resources. Chubb INA received $1.7 billion and $458 million from its subsidiaries during the six months ended June 30, 2024 and 2023, respectively.
Cash Flows
Our sources of liquidity include cash from operations, routine sales of investments, and financing arrangements. The following is a discussion of our cash flows for the six months ended June 30, 2024 and 2023.
Operating cash flows were $7.3 billion in the six months ended June 30, 2024, compared to $4.8 billion in the prior year period, primarily due to higher net premiums collected, net investment income, and the impact of the Huatai consolidation.
Cash used for investing was $6.1 billion in the six months ended June 30, 2024, compared to $2.3 billion in the prior year period, an increase of $3.8 billion, which primarily included higher net purchases of fixed maturities and equity securities of $3.6 billion.
Cash used for financing was $1.2 billion in the six months ended June 30, 2024, compared to $2.3 billion in the prior year period, a decrease in cash used for financing of $1.1 billion. This was primarily due to net proceeds from the issuance of long-term debt, net of repayments of $296 million compared with repayments of $475 million in the prior year and fewer common shares repurchased of $211 million.
We use repurchase agreements as a low-cost funding alternative. At June 30, 2024, there were $3.1 billion in repurchase agreements outstanding with various maturities over the next twelve months.

Both internal and external forces influence our financial condition, results of operations, and cash flows. Claim settlements, premium levels, and investment returns may be impacted by changing rates of inflation and other economic conditions. In many cases, significant periods of time, ranging up to several years or more, may lapse between the occurrence of an insured loss, the reporting of the loss to us, and the settlement of the liability for that loss.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Refer to Item 7A included in our 2023 Form 10-K.
Foreign currency management
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. We occasionally engage in hedging activity for planned cross border transactions. For an estimated impact of foreign currency movement on our net assets denominated in non-U.S. currencies, refer to Item 7A in our 2023 Form 10-K. This information will be updated and disclosed in interim filings if our net assets in non-U.S. currencies change materially from the December 31, 2023, balances disclosed in the 2023 Form 10-K.
Reinsurance of market risk benefits
Chubb views its MRB reinsurance business as having a similar risk profile to that of catastrophe reinsurance, with the probability of long-term economic loss relatively small at the time of pricing. Adverse changes in market factors and policyholder behavior will have an impact on both MRB gains (losses) and net income. When evaluating these risks, we expect to be compensated for taking both the risk of a cumulative long-term economic net loss, as well as the short-term accounting variations caused by these market movements. Therefore, we evaluate this business in terms of its long-term economic risk and reward.
The tables below are estimates of the sensitivities to instantaneous changes in economic inputs (e.g., equity shock, interest rate shock etc.) at June 30, 2024, for both the fair value of the MRB liability (FVL) and the fair value of specific derivative instruments held (hedge value) to partially offset the risk in the MRB reinsurance portfolio. The following assumptions should be considered when using the below tables:
•Equity shocks impact all global equity markets equally
•Our liabilities are sensitive to global equity markets in the following proportions: 80 percent—90 percent U.S. equity, and 10 percent—20 percent international equity.
•Our current hedge portfolio is sensitive only to U.S. equity markets.
•We would suggest using the S&P 500 index as a proxy for U.S. equity, and the MSCI EAFE index as a proxy for international equity.
•Interest rate shocks assume a parallel shift in the U.S. yield curve
•Our liabilities are also sensitive to global interest rates at various points on the yield curve, mainly the U.S. Treasury curve in the following proportions: up to 15 percent short-term rates (maturing in less than 5 years), 15 percent—30 percent medium-term rates (maturing between 5 years and 10 years, inclusive), and 65 percent—80 percent long-term rates (maturing beyond 10 years).

Table of Contents
•A change in AA-rated credit spreads impacts the rate used to discount cash flows in the fair value model. AA-rated credit spreads are a proxy for both our own credit spreads and the credit spreads of the ceding insurers.
•The hedge sensitivity is from June 30, 2024, market levels and only applicable to the equity and interest rate sensitivities table below.
•The sensitivities do not scale linearly and may be proportionally greater for larger movements in the market factors. Actual sensitivity of our net income may differ from those disclosed in the tables below due to fluctuations in short-term market movements.

Table of Contents
Market Risk Benefits Net Amount at Risk
All our MRB reinsurance treaties include annual or aggregate claim limits and many include an aggregate deductible which limit the net amount at risk under these programs. The tables below present the net amount at risk at June 30, 2024, following an immediate change in equity market levels, assuming all global equity markets are impacted equally.
a) Reinsurance covering the GMDB risk only

| Equity Shock
(in millions of U.S. dollars) | +20 | % |  | Flat |  | -20 | % |  | -40 | % |  | -60 | % |  | -80 | %
GMDB net amount at risk | $ | 219 |  |  | $ | 216 |  |  | $ | 375 |  |  | $ | 637 |  |  | $ | 643 |  |  | $ | 522 |
Claims at 100% immediate mortality | 131 |  |  | 138 |  |  | 147 |  |  | 138 |  |  | 126 |  |  | 112 |

The treaty limits function as a ceiling as equity markets fall. As the shocks in the table above become incrementally more negative, the impacts begin to drop due to the specific nature of these claim limits, many of which are annual claim limits calculated as a percentage of the reinsured account value. There is also an impact due to a portion of the reinsurance under which claims are positively correlated to equity markets (claims decrease as equity markets fall).
b) Reinsurance covering the GLB risk only

| Equity Shock
(in millions of U.S. dollars) | +20 | % |  | Flat |  | -20 | % |  | -40 | % |  | -60 | % |  | -80 | %
GLB net amount at risk | $ | 759 |  |  | $ | 996 |  |  | $ | 1,365 |  |  | $ | 1,897 |  |  | $ | 2,205 |  |  | $ | 2,475 |

The treaty limits cause the net amount at risk to increase at a declining rate as equity markets fall.
c) Reinsurance covering both the GMDB and GLB risks on the same underlying policyholders

| Equity Shock
(in millions of U.S. dollars) | +20 | % |  | Flat |  | -20 | % |  | -40 | % |  | -60 | % |  | -80 | %
GMDB net amount at risk | $ | 35 |  |  | $ | 41 |  |  | $ | 51 |  |  | $ | 61 |  |  | $ | 69 |  |  | $ | 76 |
GLB net amount at risk | 305 |  |  | 377 |  |  | 474 |  |  | 592 |  |  | 708 |  |  | 750 |
Claims at 100% immediate mortality | 27 |  |  | 26 |  |  | 26 |  |  | 26 |  |  | 26 |  |  | 26 |

The treaty limits cause the GMDB and GLB net amount at risk to increase at a declining rate as equity markets fall.

ITEM 4. Controls and Procedures

Chubb’s management, with the participation of Chubb’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of Chubb’s disclosure controls and procedures as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 as of June 30, 2024. Based upon that evaluation, Chubb’s Chief Executive Officer and Chief Financial Officer concluded that Chubb’s disclosure controls and procedures are effective in allowing information required to be disclosed in reports filed under the Securities Exchange Act of 1934 to be recorded, processed, summarized, and reported within time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to Chubb’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Effective July 1, 2023, Chubb discontinued the equity method of accounting to its investment in Huatai Group and applied consolidation accounting. For the three and six months ended June 30, 2024, Huatai Group represented approximately 5 percent of consolidated revenues. At June 30, 2024, Huatai group represented approximately 7 percent of total assets. We currently exclude, and are in the process of working to incorporate, Huatai Group in our evaluation of internal controls over financial reporting, and related disclosure controls and procedures.
Other than working to incorporate Huatai Group as noted above, there have been no changes in Chubb's internal controls over financial reporting during the three months ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, Chubb's internal controls over financial reporting.
