c) Accounting guidance adopted in 2023
Targeted Improvements to the Accounting for Long-Duration Contracts
Effective January 1, 2023, we adopted new guidance on the accounting for long-duration contracts (LDTI). The new accounting guidance requires more frequent updating of assumptions and a standardized discount rate for the future policy benefit liability, a requirement to use the fair value measurement model for policies with market risk benefits, simplified amortization of deferred acquisition costs, and enhanced disclosures.

With the exception of market risk benefits, we adopted this guidance on a modified retrospective basis. Under the modified retrospective basis, the liability for future policy benefits is updated to remove any amounts related to changes to the original discount rate at January 1, 2021 (the transition date) in AOCI and future cash flow assumptions are applied to contracts in force. The liability for future policy benefits prior to the transition date continues to use the original discount rate (interest accretion rate). The guidance for long-duration contracts applicable to market risk benefits, primarily assumed reinsurance programs involving minimum benefit guarantees under variable annuity contracts, was adopted on a retrospective transition approach. Under the retrospective transition approach, we calculated the fair value of market risk benefits which were previously accounted for under an insurance accounting model and recognized an adjustment to retained earnings as of January 1, 2021.

On January 1, 2021, we recognized a cumulative effect adjustment and increased beginning retained earnings by $52 million, and decreased AOCI by $1.8 billion. Results for the prior reporting periods in this report are presented in accordance with the new guidance. We also adopted the required disclosures in Note 6 Deferred acquisition costs, Note 9 Future policy benefits, Note 10 Policyholders’ account balances, Note 11 Market risk benefits, and Note 12 Separate accounts.

The impact of adoption of the new guidance on our historical financial statements is as follows:

Excluded from the table above is the reclassification of separate accounts assets, separate account liabilities, and Policyholders' account balances as separate line items on the consolidated balance sheets. Separate accounts assets were previously classified in Other assets, and separate account liabilities and Policyholders' account balances were previously classified in Accounts payable, accrued expenses, and other liabilities.

Significant accounting policies
The following accounting policies have been updated to reflect the adoption of LDTI. Refer to Note 1 in the 2022 Form 10-K for a complete description of our accounting policies.

Deferred policy acquisition costs (DAC)
Policy acquisition costs on long-duration contracts are grouped by contract type and issue year into cohorts consistent with the grouping used in estimating the associated liability. Deferred policy acquisition costs are amortized on a constant level basis over the expected term of the related contracts to approximate straight-line amortization. The constant level basis used for amortization is the face amount in force and is projected using the same assumptions used in estimating the liability for future policy benefits. If those projected assumptions change in future periods, they will be reflected in the cohort level amortization basis at that time. Unexpected changes in the in-force portfolio, due to variances in mortality and lapse experience, are recognized over the contract term. Changes in future mortality and lapse assumptions are also recognized prospectively over the remaining expected contract term.

Future policy benefits
For traditional and limited-payment contracts, contracts are grouped into cohorts by contract type and issue year to determine a liability for future policy benefits. The future policy benefit liability (FPBL) is the present value of estimated future policy benefits to be paid to or on behalf of policyholders and certain related expenses less the present value of estimated future net premiums to be collected from policyholders, and is accrued as premium revenue is recognized. The valuation of this liability requires management to make estimates and assumptions regarding expenses, mortality, and persistency. Estimates are primarily based on historical experience. Actual results could differ materially from these estimates.

The liability is adjusted for differences between actual and expected experience. With the exception of the expense assumption, we review our future cash flow assumptions at least annually to determine if the net premium ratio (NPR), the mechanism used to record the liability as premium is earned, used to calculate the liability should be changed at that time. We have elected to use expense assumptions that are locked in at contract inception and are not subsequently reviewed or updated. Each quarter, we update the cash flows expected over the entire life of each cohort for actual historical experience and projected future cash

flows. These updated cash flows are used to calculate the revised NPR, which is used to derive an updated FPBL as of the beginning of the current reporting period, discounted at the original contract issuance discount rate. This amount is then compared to the carrying amount of the liability as of that same date, but before the updating of cash flow assumptions, to determine the current period change in FPBL. This current period change in the liability is the liability remeasurement gain or loss and is recorded in Policy benefits in the Consolidated statements of operations. In subsequent periods, the revised NPR is used to measure the FPBL until future revisions become required.

For traditional and limited-payment contracts, the discount rate assumption based on an upper-medium grade fixed-income instrument yield. An equivalent rate is derived based on A-credit-rated fixed-income instruments with similar duration to the liability. The discount rate assumption is updated quarterly and used to remeasure the liability at each reporting date, with the resulting change reflected in Other comprehensive income. For liability cash flows that are projected beyond the duration of market-observable A-credit-rated fixed-income instruments, we use the last market-observable yield level, as the basis for a linear interpolation to determine yield assumptions for durations that do not have market-observable yields.

Deferred profit liability
For limited-payment products, gross premiums received in excess of net premiums are deferred at initial recognition as a deferred profit liability (DPL) and recorded as a component of Future policy benefits in the Consolidated balance sheets. Net premiums are measured using actual cash flows and future cash flow assumptions consistent with those used in the measurement of the liability for future policy benefits and remeasured quarterly. The DPL is amortized in proportion to the discounted in-force policies. Interest is accreted on the balance of the DPL using the discount rate consistent with the interest accretion on the FPBL. The recalculated DPL, including adjusted amortization through the current period, is compared to the current carrying amount and the difference is recognized as an adjustment to Policy benefits in the Consolidated statements of operations as a remeasurement gain or loss.

Market risk benefits
Chubb reinsures various death and living benefit guarantees associated with variable annuities issued primarily in the United States, which are referred to as market risk benefits. These reinsurance contracts provide both protection to the ceding entity from other-than-nominal capital market risk and expose us to other-than-nominal capital market risk.

Market risk benefits are measured at fair value using a valuation model based on current net exposures, market data, our experience, and other factors. Changes in fair value are recognized in Market risk benefits gains (losses) in the Consolidated statements of operations, except the change in fair value due to a change in the instrument-specific credit risk, which is recognized in other comprehensive income. Refer to Note 11 for additional information.

2. Acquisitions

Cigna’s Accident and Health (A&H) and Life Insurance Business in Asian Markets

On July 1, 2022, we completed the acquisition of the life and non-life insurance companies that house the personal accident, supplemental health, and life insurance business of Cigna in several Asian markets. Chubb paid approximately $5.4 billion in cash for the operations, which include Cigna's accident and health (A&H) and life business in Korea, Taiwan, New Zealand, Thailand, Hong Kong, and Indonesia, collectively referred to as Cigna's business in Asia. This complementary strategic acquisition expands our presence and advances our long-term growth opportunity in Asia. Effective July 1, 2022, the results of operations of this acquired business are reported primarily in our Life Insurance segment and, to a lesser extent, our Overseas General Insurance segment. Refer to the 2022 Form 10-K for additional information on this acquisition.

The acquisition of Cigna's business in Asia generated $1,177 million of goodwill, attributable to expected growth and profitability, and $309 million of other intangible assets. None of the goodwill is expected to be deductible for income tax purposes. Additionally, the acquisition of Cigna's business in Asia generated $3,633 million of value of business acquired (VOBA). Chubb financed the transaction through a combination of available cash and $2.0 billion in repurchase agreements that expired at the end of 2022.

The following table summarizes Chubb's best estimate of fair value of the assets acquired and liabilities assumed at July 1, 2022. These estimates remain preliminary and are subject to adjustment. While they are not expected to be materially different than those shown, any material adjustments to the estimates will be reflected, retroactively, as of the date of the acquisition as a measurement period adjustment.

At March 31, 2023, the tax benefit on certain unrealized losses in our investment portfolio was reduced by a valuation allowance of $646 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 capacity and available tax planning strategies.

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 March 31, 2023 and December 31, 2022 are investments, primarily fixed maturities, totaling $16,021 million and $15,721 million, respectively, and cash of $94 million and $115 million, respectively.

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

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries

market information that would allow them to make a fair value estimate. Based on our understanding of the market inputs used by the pricing services, all applicable investments have been valued in accordance with 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.

Other investments
Fair values for the majority of Other investments 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. Certain of our long-duration contracts are supported by assets that do not qualify for separate account reporting under GAAP. These assets 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 also include equity securities, classified within Level 1 and fixed maturities, classified within Level 2, held in rabbi trusts maintained by Chubb for deferred compensation plans and supplemental retirement plans and are classified within the valuation hierarchy on the same basis as other equity securities and fixed maturities.

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
18

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries

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.

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 claims and, therefore, an increase in market risk benefits (MRB) reserves and our MRB reinsurance business. 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 based on unobservable inputs are classified within Level 3. Other derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets.

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.

VOBA
Value of business acquired (VOBA) represents the fair value of the future profits of in-force long duration contracts, and is amortized in relation to the profit emergence of the underlying contracts, in a manner similar to deferred acquisition costs. The VOBA calculation is based on many factors including mortality, morbidity, persistency, investment yields, expenses, and the discount rate, with the discount rate being the most significant factor.

The following table presents a roll-forward of VOBA:

Gross unpaid losses and loss expenses decreased $330 million for the three months ended March 31, 2023, principally reflecting underlying exposure growth that was more than offset by the favorable impact of foreign currency movement, a large payment related to the Boy Scouts of America agreement, and a non-recurring transaction in the quarter. In addition, there was an increase in net unpaid losses and loss expenses of $236 million reflecting the factors noted above as well as higher collections in the quarter.

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:

Total$(12)$(228)$(240)
Significant prior period movements by segment, principally driven by reserve reviews completed during each respective period, are discussed in more detail below. The remaining net development for long-tail lines and short-tail business for each segment and Corporate comprises numerous favorable and adverse movements across a number of lines and accident years, none of which is significant individually or in the aggregate.
North America Commercial P&C Insurance. Net favorable development for the three months ended March 31, 2023, was $72 million favorable with $81 million favorable in short-tail lines and $9 million adverse in long-tail lines. The short tail development was primarily in surety and A&H, partially offset by adverse development in property and marine due to the net impact of positive development from Hurricane Ian and negative development from Winter Storm Elliott. The long tail development was the net of favorable developments in specialty casualty and workers comp due to lower than expected paid and reported loss activity offset by adverse development in general liability and certain financial lines due to higher than expected development.
Net favorable development for the three months ended March 31, 2022, included favorable development in A&H lines of $76 million, which experienced lower than expected loss emergence. The favorable development was partially offset by adverse development in commercial umbrella and excess portfolios of $60 million driven by higher than expected loss emergence.
North America Personal P&C Insurance. Net adverse development for the three months ended March 31, 2023, was $17 million with no individually significant movements. Net favorable development for the three months ended March 31, 2022, included favorable development in the homeowners line of business from a reserve release due to lower than expected paid and reported loss activity attributable to the indirect effects of COVID related economic slowdown.
Overseas General Insurance. Net favorable development for the three months ended March 31, 2023, included $85 million in property lines, driven by favorable catastrophe development of $43 million, and non-catastrophe loss emergence in Continental Europe and the U.K.
Net favorable development for the three months ended March 31, 2022, included favorable development in property and A&H lines of business.

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:

Excluded from the table above are MRB gains (losses) of $(89) million and $26 million for the three months ended March 31, 2023 and 2022, 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 reinsurance, Chubb estimates fair value using an internal valuation model which includes a number of factors including interest rates, equity markets, credit risk, current account value, market volatility, expected annuitization rates and other policyholder behavior, and changes in policyholder mortality. All reinsurance treaties contain claim limits, which are also factored into the valuation model.

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

The most significant policyholder behavior assumptions include lapse rates for MRBs and the annuitization rates which is applicable to GLB only. 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. In general, the base lapse function assumes low lapse rates during the surrender charge period, followed by a "spike" lapse rate in the year immediately following the surrender charge period, and then reverting to an ultimate lapse rate, typically over a 2-year period. This base rate is adjusted downward for policies with more valuable guarantees (policies with guaranteed values far in excess of their account values). Partial withdrawals and the impact of older policyholders with tax-qualified contracts (due to required minimum distributions) are also reflected in our modeling.

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. All GLB reinsurance treaties include claim limits to protect Chubb in the event that actual annuitization behavior is significantly higher than expected. In general, Chubb assumes that GLB annuitization rates will be

35

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries

higher for policies with more valuable guarantees (policies with guaranteed values far in excess of their account values). Chubb also assumes that GLB annuitization rates increase as policyholders get older. In addition, it is also assumed that GLB annuitization rates are higher in the first year immediately following the waiting period (the first year the policies are eligible to annuitize using the GLB) in comparison to all subsequent years. Chubb does not yet have fully credible annuitization experience for all clients.

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.

12. 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.

13. 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 MRB book of business. Investment derivative instruments and derivatives designated as hedges for accounting purposes are recorded in either Other assets (OA) or Accounts payable, accrued expenses, and other liabilities (AP); convertible bonds are recorded in Fixed maturities available for sale (FM AFS); and convertible equity securities are recorded in Equity securities (ES) in the Consolidated balance sheets. 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.

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.

(i) Cross-currency swaps - fair value hedges
In September 2022, Chubb entered into 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 March 31, 2023, of our euro denominated debt, by converting cash flows back into the U.S. dollar.

These fair value hedges are carried at fair value. The hedges are expected to be highly effective, with gains or losses on the fair value hedges offsetting the foreign currency remeasurement on the hedged euro denominated senior notes within Net realized gains (losses). The remaining change in fair value is recorded in Other comprehensive income (OCI), with an immaterial amount recorded in Interest expense.

For the three months ended March 31, 2023, we recognized a net loss of $17 million, comprising $20 million of net realized gains, $4 million of interest expense, and a remaining change in fair value of $33 million pre-tax of other comprehensive loss recorded within OCI.

(ii) Cross-currency swaps - net investment hedges
In September 2022, Chubb entered into 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.

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

For the three months ended March 31, 2023, we recognized a net loss of $23 million, comprising $26 million pre-tax of cumulative translation losses recorded in OCI, and $3 million of interest income.

(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

39

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:

At March 31, 2023, and December 31, 2022, our repurchase agreement obligations of $1,420 million and $1,419 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, and the repurchase agreement obligation is recorded in Repurchase agreements in the Consolidated balance sheets.

(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 March 31, 2023, and December 31, 2022, commitments to purchase fixed income securities over the next several years were $810 million and $770 million, respectively.

f) Other investments
At March 31, 2023, included in Other investments in the Consolidated balance sheet are investments in limited partnerships and partially-owned investment companies with a carrying value of $12.4 billion. In connection with these investments, we have commitments that may require funding of up to $6.7 billion over the next several years. At December 31, 2022, these investments had a carrying value of $12.0 billion with commitments that may have required funding of up to $7.4 billion.

g) Income taxes
At March 31, 2023, $66 million of unrecognized tax benefits remain outstanding. 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 March 31, 2023, and December 31, 2022, the right-of-use asset was $571 million and $607 million, respectively, recorded within Other assets, and the lease liability was $595 million and $633 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.

14. 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 March 31, 2023, our Common Shares had a par value of CHF 24.15 per share.

At our May 2022 and 2021 annual general meetings, our shareholders approved annual dividends for the following year of up to $3.32 per share and $3.20 per share, respectively, which were paid in four quarterly installments of $0.83 per share and $0.80 per share, respectively, at dates determined by the Board of Directors (Board) after the annual general meetings by way of a distribution from capital contribution reserves, transferred to free reserves for payment.

Dividend distributions per Common Share for the three months ended March 31, 2023 and 2022, were $0.83 (CHF 0.77) and $0.80 (CHF 0.74), respectively.

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 the Chubb Limited Extraordinary General Meeting of Shareholders, held on November 3, 2021, shareholders approved the cancellation of 14,465,400 shares repurchased under our share repurchase program during the first six months of 2021. The capital reduction by cancellation of shares was subject to publication requirements and a two-month waiting period in accordance with Swiss law and became effective on January 17, 2022. At our May 2022 annual general meeting, held on May 19, 2022, our shareholders approved the cancellation of 13,179,100 shares purchased under our share repurchase program during the last six months of 2021. The capital reduction by cancellation of shares was subject to publication requirements and a two-month waiting period in accordance with Swiss law and became effective on August 4, 2022. During the three months ended March 31, 2023, 2,010,400 shares were repurchased and 1,574,224 net shares were issued under employee share-based compensation plans. At March 31, 2023, 32,217,934 Common Shares remain in treasury.

Chubb Limited securities repurchase authorizations
The Board has authorized share repurchase programs as follows:

One-time incremental share repurchase program of $5.0 billion of Chubb Common Shares from July 19, 2021, through June 30, 2022; and

15. 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 23, 2023, Chubb granted 1,540,002 stock options with a weighted-average grant date fair value of $51.32 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-based restricted stock awards. Chubb generally grants service-based restricted stock and restricted stock units with a 4-year vesting period, based on a graded vesting schedule. The performance-based restricted stock awards granted comprise target awards and premium awards that cliff vest at the end of a 3-year performance period based on both 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 our peer group. The restricted stock is principally granted at market close price on the grant date. On February 23, 2023, Chubb granted 785,319 service-based restricted stock awards, 315,545 service-based restricted stock units, and 407,825 performance-based stock awards to employees and officers with a grant date fair value of $208.60 each. Each restricted stock unit represents our obligation to deliver to the holder one Common Share upon vesting.

This line item also includes net income of $14 million and $42 million attributable to our investments in Huatai for the three months ended March 31, 2023 and 2022, respectively.
(2)     Related to gains (losses) from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP.
Other income and expense includes equity in net income of partially-owned entities, which includes our share of net income or loss, both underlying operating income and mark-to-market movement, related to partially-owned investment companies (private equity) and partially-owned insurance companies. 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 reporting under GAAP. The offsetting movement in the separate account liabilities is included in Policy benefits in the Consolidated statements of operations. 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.

18. Segment information

Chubb operates through six business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insurance, Overseas General Insurance, Global Reinsurance, and Life Insurance. These segments distribute their products through various forms of brokers, agencies, and direct marketing programs. All business segments have established relationships with reinsurance intermediaries. Segment results for the three months ended March 31, 2023, include the results of Cigna's business in Asia, which are principally assigned to our Life Insurance segment and, to a lesser extent, our Overseas General Insurance segment according to the nature of the business written.

Management uses underwriting income (loss) as the basis for segment performance for its P&C operations. P&C underwriting income (loss) excludes the Life Insurance segment and is calculated 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, and income tax 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 related to the acquisition of Cigna's A&H and Life insurance companies in several Asian markets. 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

47

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)
Chubb Limited and Subsidiaries

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 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.

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 March 31, 2023

Net income was $1.9 billion compared with $2.0 billion in the prior year period. Net income in the current quarter included the results of Cigna's business acquired during the third quarter of 2022 and record net investment income. Net income is slightly lower compared to the prior year, reflecting market risk benefit losses of $115 million, from lower interest rates and higher volatility, partially offset by higher equity markets, compared to a gain of $49 million in the prior year.

Consolidated net premiums written were $10.7 billion, up 16.6 percent, or 18.3 percent in constant dollars, with Cigna's business in Asia adding 8.3 percentage points, or 8.4 percentage points in constant dollars. P&C net premiums written were up 9.3 percent, or 11.0 percent in constant dollars, with commercial and consumer lines up 11.5 percent and 9.4 percent, respectively.

Consolidated net premiums earned were $10.1 billion, up 16.1 percent, or 17.7 percent in constant dollars, with Cigna's business in Asia adding 8.7 percentage points, or 8.8 percentage points in constant dollars. P&C net premiums earned increased 8.3 percent, or 9.8 percent in constant dollars, with commercial and consumer lines up 10.5 percent and 8.0 percent, respectively.

Total pre-tax and after-tax catastrophe losses were $458 million (5.1 percentage points of the P&C combined ratio) and $382 million, respectively, compared with $333 million (4.0 percentage points of the P&C combined ratio) and $290 million, respectively, in the prior year period. Catastrophe losses in the current quarter were primarily from global weather-related events.
Total pre-tax and after-tax favorable prior period development were $196 million (2.2 percentage points of the combined ratio) and $149 million, respectively. The $196 million in pre-tax development was comprised of $202 million in favorable non-catastrophe development and $6 million in adverse catastrophe-related development. This compares with $240 million (3.2 percentage points of the combined ratio) and $195 million, respectively, in the prior year period.

The P&C combined ratio was 86.3 percent compared with 84.3 percent in the prior year period. The current year P&C combined 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 83.4 percent compared with 83.5 percent in the prior year period.

Net investment income was a record $1.1 billion compared with $822 million in the prior year period, primarily reflecting higher reinvestment rates.

Operating cash flow was $2.25 billion compared with $2.44 billion in the prior year period.

Effective January 1, 2023, we adopted the Long-Duration Targeted Improvements (LDTI) U.S. GAAP guidance, which principally impacted the Life Insurance segment. Financial data for the prior reporting periods in this report are adjusted, as applicable, and are presented in accordance with the new guidance. The impact to 2022 results was immaterial.

Shareholders' equity increased by $2.5 billion in the quarter, primarily from net income of $1.9 billion and net unrealized gains on investments of $1.6 billion after-tax from lower interest rates. In addition, shareholders' equity reflected total capital returned to shareholders in the quarter of $772 million, including share repurchases of $428 million, at an average purchase price of $212.81 per share, and dividends of $344 million.

The increase in consolidated net premiums written for the three months ended March 31, 2023, reflects growth across most product lines driven by strong renewal retention, positive rate increases, and new business. Cigna's business in Asia contributed $758 million for the three months ended March 31, 2023.

Commercial casualty grew in all regions globally driven by strong premium retention, including both rate and exposure increases, and strong new business.
Workers' compensation growth was due to strong premium retention and rate increases in North America.
Financial lines decreased, reflecting lower new business and lower rates in North America.
Surety increased due to strong new business in North America.
Commercial multiple peril increased due to strong premium retention, including both rate and exposure increases, and strong new business in North America.
Property and other short-tail lines grew globally due to strong premium retention, including both rate and exposure increases, and strong new business.
Agriculture increased due to underlying growth in crop insurance, reflecting higher commodity prices. In addition, the prior year included a return of premium to the U.S. government of $161 million.
Personal lines grew principally in North America, with growth strongest in our high net worth business.
Global A&H – P&C increased due to growth in Asia, including $34 million from the acquisition of Cigna’s business in Asia, and higher new business and increased consumer activity, including higher travel volume, in Europe, Latin America, and Japan.
Reinsurance lines increased primarily due to continued growth in the portfolio, driven by new business.

Global A&H – Life increased due to the acquisition of Cigna’s business in Asia, which contributed $570 million to growth. Our North American Combined Insurance supplemental A&H business decreased primarily due to the non-renewal of a large program.
Life increased driven substantially by growth in Asia, principally from new business in Hong Kong, and the acquisition of Cigna's business in Asia, which contributed $154 million to growth.
For additional information on net premiums written, refer to the segment results discussions.

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 March 31, 2023, net premiums earned increased $1.4 billion, up 16.1 percent, or 17.7 percent in constant dollars. P&C net premiums earned increased 8.3 percent, or 9.8 percent in constant dollars, comprising growth in commercial and consumer lines of 10.5 percent and 8.0 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.

Prior period development 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.

Three Months Ended
March 31
(in millions of U.S. dollars)20232022
Catastrophe losses$458 $333 
Favorable prior period development$196 $240 

Catastrophe losses through March 31, 2023 and 2022, were primarily from the following events:
2023: Severe weather-related events in the U.S. and internationally; and New Zealand storms.
2022: Australia storms, Colorado wildfires, and other severe weather-related events in the U.S. and internationally.

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.

Pre-tax net favorable PPD for the three months ended March 31, 2023, was $196 million, comprising $202 million in favorable non-catastrophe development and $6 million in adverse catastrophe-related development. This development includes adverse development of $19 million in long-tail lines, principally from accident years 2013 through 2017. The remaining net favorable development of $215 million in short-tail lines is primarily in surety and A&H lines.

Pre-tax net favorable PPD for the three months ended March 31, 2022, was $240 million, with 5 percent in long-tail lines, principally from accident years 2018 and prior, and 95 percent in short-tail lines, primarily in A&H, property, and surety lines.

Refer to the prior period development discussion in Note 8 to the Consolidated Financial Statements for additional information.

P&C Combined Ratio
In evaluating our segments, excluding Life Insurance financial performance, we use the P&C combined ratio. We calculate this ratio by dividing the respective expense amounts by net premiums earned. We do not calculate this ratio for the Life Insurance segment as we do not use this measure to monitor or manage that segment. A P&C combined ratio under 100 percent indicates underwriting income, and a combined ratio exceeding 100 percent indicates underwriting loss.

P&C Combined ratio86.3 %84.3 %

The loss and loss expense ratio increased for the three months ended March 31, 2023, reflecting higher catastrophe losses and lower favorable prior period development. The CAY loss ratio excluding catastrophe losses decreased for the three months ended March 31, 2023, primarily from a higher percentage of net premiums earned from lines with a lower loss ratio and earned rate and exposure exceeding loss cost trends in certain lines.

The policy acquisition cost ratio decreased for the three months ended March 31, 2023, primarily due to the favorable impact of higher net premiums earned.

The administrative expense ratio for the three months ended March 31, 2023 remained essentially flat as higher employee-related expenses and increased investment to support growth was offset by the favorable impact of higher net premiums earned.

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. Refer to the Life Insurance segment operating results section for further discussion.

For the three months ended March 31, 2023 and 2022, Policy benefits were $797 million and $373 million, respectively, which included (gains) losses from fair value changes in separate account liabilities that do not qualify for separate account reporting under GAAP of $(25) million and $(31) million, respectively. The offsetting movements of these liabilities are recorded in Other (income) expense on the Consolidated statements of operations. Excluding the separate account gains and losses, Policy benefits were $822 million and $404 million for the three months ended March 31, 2023 and 2022, respectively.

2023: U.S. flooding, hail, tornadoes, wind events, and winter storm losses.
2022: Winter storm losses and other severe weather-related events in the U.S.

Refer to Note 8 in the Consolidated Financial Statements for detail on prior period development.

Premiums
Net premiums written increased $249 million, or 6.2 percent for the three months ended March 31, 2023, reflecting strong premium retention, including both rate and exposure increases, and strong new business in certain lines. The increase in premiums was across most lines of business, including property, commercial multiple peril, A&H, and excess casualty. Partially offsetting the increase was a 1.3 percentage point impact of loss portfolio transfer transactions year-over-year.

Net premiums earned increased $255 million, or 6.2 percent for the three months ended March 31, 2023, reflecting the growth in net premiums written described above.

Combined Ratio
The loss and loss expense ratio increased for the three months ended March 31, 2023, primarily from higher catastrophe losses and lower favorable prior period development. Prior period development for the three months ended March 31, 2023, comprised $112 million of favorable development, partially offset by a charge of $40 million related to development from the 2022 late-season catastrophes. The CAY loss ratio excluding catastrophe losses decreased for the three months ended March 31, 2023, primarily from a higher percentage of net premiums earned from property lines that have a lower loss ratio and earned rate and exposure exceeding loss cost trends in certain lines.

The administrative expense ratio increased for the three months ended March 31, 2023, primarily due to higher pension expenses reflecting unfavorable market conditions, partially offset by the favorable impact of higher net premiums earned. We expect the higher pension expense to continue through 2023.

Combined Ratio
The loss and loss expense ratio increased for the three months ended March 31, 2023, primarily reflecting the impact of higher catastrophe losses in the current quarter, including a charge of $9 million related to the development from 2022 late-season catastrophes, and a reserve release in the prior year quarter due to lower than expected paid and reported loss activity attributable to the indirect effects of COVID related economic slowdown. The CAY loss ratio excluding catastrophe losses increased for the three months ended March 31, 2023, primarily reflecting higher auto losses, partially offset by homeowners earned rate and exposure exceeding lost cost trends.

The administrative expense ratio increased for the three months ended March 31, 2023, primarily due to higher year-over-year pension expenses from unfavorable market conditions, partially offset by the favorable impact of higher net premiums earned. We expect the higher pension expense to continue through 2023.


North America Agricultural Insurance

Refer to Note 8 in the Consolidated Financial Statements for detail on prior period development.

Premiums
Net premiums written increased $231 million for the three months ended March 31, 2023, reflecting growth in MPCI due to higher commodity prices, and strong new business in Chubb Agribusiness. In addition, growth reflects the return of premium to the U.S. government of $161 million in the first quarter of 2022 as part of the profit-sharing agreement. Under the profit-sharing agreement, we returned additional premiums to the government because of the lower losses experienced in certain states in 2021.

Net premiums earned increased $188 million for the three months ended March 31, 2023, reflecting the factors described above.

Combined Ratio
The CAY loss ratio excluding catastrophe losses increased for the three months ended March 31, 2023, primarily from higher premiums earned from MPCI, which have a higher loss ratio, and a 1.5 percentage point increase from a year-over-year impact from our crop commodity price hedge activity which produced a loss this quarter versus a gain last year.

The CAY administrative expense ratio increased for the three months ended March 31, 2023, reflecting lower Administrative and Operating (A&O) reimbursements on the MPCI business.

Premiums
Net premiums written increased $184 million, or $297 million on a constant dollar basis, for the three months ended March 31, 2023, reflecting growth in commercial lines of 6.2 percent, or 10.8 percent on a constant-dollar basis, and growth in consumer lines of 5.6 percent, or 8.6 percent on a constant-dollar basis.

Our European division increased for the three months ended March 31, 2023, supported by both our wholesale and retail divisions. The growth in commercial lines of 6.0 percent, or 11.7 percent on a constant-dollar basis, was primarily driven by higher new business, and positive rate increases, including commercial property and casualty lines. Consumer lines declined 2.9 percent, but grew 4.5 percent on a constant-dollar basis primarily due to increased travel volume in A&H.

Latin America increased for the three months ended March 31, 2023. The growth in commercial lines of 10.1 percent, or 9.4 percent on a constant-dollar basis, is driven by exposure increases, positive rate increases, and new business, primarily property and casualty lines. Consumer lines grew 8.5 percent, or 2.4 percent on a constant-dollar basis due to increased A&H.

Asia Pacific increased for the three months ended March 31, 2023. The growth in commercial lines of 11.3 percent, or 14.9 percent on a constant-dollar basis, is driven by higher new business, higher retention and positive rate increases, including property and casualty lines. The growth in consumer lines of 16.7 percent, or 22.5 percent on a constant-dollar basis, increased primarily from travel in A&H. The acquisition of Cigna's business in Asia contributed $34 million in 2023.

Japan increased for the three months ended March 31, 2023, on a constant-dollar basis, primarily from higher new business in A&H.

Net premiums earned increased $158 million, or $252 million on a constant-dollar basis, for the three months ended March 31, 2023, reflecting the increase in commercial and consumer net premiums written described above.

The loss and loss expense ratio decreased for the three months ended March 31, 2023, due to lower catastrophe losses and higher favorable prior period development related to a reserve release from 2022 late-season catastrophes.

The policy acquisition cost ratio decreased for the three months ended March 31, 2023, primarily due to a change in the mix of business, including less premiums earned from personal lines that have a higher acquisition cost ratio and higher premiums earned from commercial lines that have a lower acquisition cost ratio than consumer lines.

The administrative expense ratio decreased for the three months ended March 31, 2023, reflecting the favorable impact of higher net premiums earned, partially offset by increased investment to support growth.

Administrative expenses increased $14 million for the three months ended March 31, 2023, primarily due to increased spending to support digital growth initiatives.

Cigna integration expenses of $22 million for the three months ended March 31, 2022, 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 17 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. Our held to maturity investment portfolio is reported at amortized cost, net of valuation allowance.

Table of Contents





The effect of market movements on our fixed maturities 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 e) to the Consolidated Financial Statements in our 2022 Form 10-K. 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 gains of $1,786 million in our investment portfolio for the three months ended March 31, 2023 were principally the result of a decrease in interest rates. In addition, there were pre-tax net realized losses of $200 million, comprising losses from sales of fixed maturities, derivative losses, and impairments on fixed income securities.

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 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 months ended March 31, 2023 our ETR was 16.9 percent compared to 15.3 percent in the prior year period. The increase in the ETR from the prior year period was due to an increase in income in higher tax rate jurisdictions driven by the Cigna acquisition and an increase in the enacted UK tax rate, partially offset by discrete tax items.

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.

Book value per common share is shareholders’ equity divided by the shares outstanding. Tangible book value per common share is shareholders’ equity less goodwill and other intangible assets, net of tax, divided by the shares outstanding. We believe that book value comparisons to less acquisitive peer companies are more meaningful when adjusted for goodwill and other intangible assets. The calculation of tangible book value per share does not consider the embedded goodwill attributable to our investments in partially-owned insurance companies until we consolidate.

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.

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, net premiums earned adjustments on PPD, prior period expense adjustments and reinstatement premiums 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.

Amortization of Purchased Intangibles and Other Amortization
Amortization of purchased intangibles
Amortization expense related to purchased intangibles was $72 million and $71 million for the three months ended March 31, 2023 and 2022, respectively.

At March 31, 2023, the deferred tax liability associated with the Other intangible assets (excluding the fair value adjustment on Unpaid losses and loss expense) was $1,206 million.

The following table presents, as of March 31, 2023, the expected reduction to the deferred tax liability associated with the amortization of Other intangible assets, at current foreign currency exchange rates, for the second through fourth quarters of 2023 and for the next five years:

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 34.7 percent for the three months ended March 31, 2023, primarily due to higher reinvestment rates on fixed maturities.

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:

Interest Expense
Interest expense for the three months ended March 31, 2023, comprised $165 million related to fixed expenses on existing debt obligations and variable expenses, and a $5 million benefit related to the amortization of the fair value of debt assumed in the Chubb Corp acquisition. The variable expenses relate to fees from the usage of certain facilities, including letters of credit, and interest on held collateral and repurchase agreements. Interest expense for the first quarter of 2023 was higher than expected primarily due to rising interest rates on held collateral. Based on our existing fixed debt obligations and projected variable expenses, we now expect pre-tax interest expense on these items to be approximately $495 million for the remainder of 2023, or $165 million each quarter. For more information on our debt obligations, refer to Note 9 to the Consolidated Financial Statements, under Item 8 in our 2022 Form 10-K.


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 March 31, 2023. The portfolio is externally managed by independent, professional investment managers and is broadly diversified across geographies, sectors, and issuers. Other investments principally comprise direct investments, investment funds, and limited partnerships. 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 closely monitor investment manager compliance with portfolio guidelines.

We estimate that a 100 basis point (bps) increase in interest rates would reduce the valuation of our fixed income portfolio by approximately $4.7 billion at March 31, 2023. The following table shows the fair value and cost/amortized cost, net of valuation allowance, of our invested assets:

The fair value of our total investments increased $2.2 billion during the three months ended March 31, 2023, primarily due to the investing of operating cash flow and unrealized gains on fixed maturities due to decreasing interest rates. This increase was partially offset by the payment of our $475 million 2.7 percent senior notes due March 2023 and share repurchases.

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.
Our exposure to the euro results primarily from Chubb European Group SE which is headquartered in France and offers a broad range of coverages throughout the European Union, Central, and Eastern Europe. Chubb primarily invests in Euro denominated investments to support its local currency insurance obligations and required capital levels. 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 44 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 March 31, 2023, our corporate fixed income investment portfolio included below-investment grade and non-rated securities which, in total, comprised approximately 16 percent of our fixed income portfolio. Our below-investment grade and non-rated portfolio includes over 1,700 issuers, with the greatest single exposure being $156 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. Sixteen 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 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:

(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.

Future policy benefits

Effective January 1, 2023, Chubb adopted the long-duration targeted improvement (LDTI) U.S. GAAP accounting guidance which affects the recognition, measurement, presentation, and disclosure requirements for long-duration contracts. For a discussion of our critical accounting estimates, refer to Item 7 in our 2022 Form 10-K.

Asbestos and Environmental (A&E)
There was no significant A&E reserve activity during the three months ended March 31, 2023. A&E reserves are included in Corporate. Refer to our 2022 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, including 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 March 31, 2023, and does not represent our expected catastrophe losses for any one year.

(1)    Worldwide aggregate is comprised of losses arising from tropical cyclones, convective storms, earthquakes, U.S. wildfires, and floods in the U.S., Canada, and Europe, and excludes "non-modeled" perils such as man-made and other catastrophe risks including pandemic.
(2)    U.S. hurricane losses include losses from wind, storm-surge, and related precipitation-induced flooding.
(3)    California earthquakes include the fire-following sub-peril.

The PML for worldwide and key U.S. peril regions are based on our in-force portfolio at January 1, 2023, and reflect the April 1, 2023, reinsurance program (see Global Property Catastrophe Reinsurance Program section) as well as inuring reinsurance protection coverages. 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 $3,441 million (or 6.5 percent of our total shareholders’ equity at March 31, 2023). Effective December 31, 2022, our worldwide PMLs include losses from floods in Canada and Europe. Additionally, U.S. hurricane PMLs include losses from hurricane related precipitation-induced flooding.

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, 2023. 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 2022 Form 10-K for more information on man-made and other catastrophes.

Global Property Catastrophe Reinsurance Program
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, 2023, through March 31, 2024, with no material changes in coverage from the expiring program. The program consists of three layers in excess of losses retained by Chubb on a per occurrence basis. In addition, 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, 2023, through March 31, 2024, 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.

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.

For the three months ended March 31, 2023, we repurchased $428 million of Common Shares in a series of open market transactions under the Board of Directors (Board) share repurchase authorization. At March 31, 2023, there were 32,217,934 Common Shares in treasury with a weighted-average cost of $165.77 per share, and $1.2 billion in share repurchase authorization remained through June 30, 2023. For the period April 1, 2023, through May 1, 2023, we repurchased 215,400 Common Shares for a total of $43 million in a series of open market transactions under the share repurchase authorization. At May 1, 2023, $1.2 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 14 to the Consolidated Financial Statements for a discussion of our dividend methodology.

At our May 2022 annual general meeting, our shareholders approved an annual dividend for the following year of up to $3.32 per share, or CHF 3.22 per share, calculated using the USD/CHF exchange rate as published in the Wall Street Journal on May 19, 2022, expected to be paid in four quarterly installments of $0.83 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 2023 annual general meeting, and is authorized to abstain from distributing a dividend at its discretion. The four quarterly installments each of $0.83 per share were distributed by the Board as expected. The annual dividend approved in May 2022 represented a $0.12 per share increase ($0.03 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:

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 March 31, 2023, our usage under these facilities was $1.4 billion 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 March 31, 2023. 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 three months ended March 31, 2023, 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 $225 million and $1.0 billion from its Bermuda subsidiaries during the three months ended March 31, 2023 and 2022, respectively.

The U.S. insurance subsidiaries of Chubb INA Holdings Inc. (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 three months ended March 31, 2023 and 2022. 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 no dividends from its subsidiaries during the three months ended March 31, 2023 and 2022.

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 three months ended March 31, 2023 and 2022.

Operating cash flows were $2.3 billion in the three months ended March 31, 2023, compared to $2.4 billion in the prior year period.

Cash used for investing was $570 million in the three months ended March 31, 2023, compared to $995 million in the prior year period, a decrease of $425 million. Cash used for investing in the current period included lower private equity contributions, net of distributions received, of $351 million and lower net purchases of equity securities and fixed maturities of $148 million.

Cash used for financing was $1.4 billion in the three months ended March 31, 2023, compared to $1.3 billion in the prior year period. The increase of $108 million is from the repayment of long-term debt of $475 million in the current year, partially offset by fewer common shares repurchased of $456 million.

We use repurchase agreements as a low-cost alternative. At March 31, 2023, there were $1.4 billion in repurchase agreements outstanding with various maturities over the next two 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 2022 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 2022 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, 2022, balances disclosed in the 2022 Form 10-K.

Reinsurance of market risk benefits
Effective January 1, 2023, we adopted new U.S. GAAP accounting guidance for long-duration contracts that affects the accounting for GMDB and GLB liabilities, collectively referred to as market risk benefits (MRB). MRB are measured at fair value using a valuation model based on current net exposures, market data, our experience, and other factors. Changes in fair value are recorded to Market risk benefits gains (losses) in the Consolidated statements of operations, except for the change in fair value due to a change in the instrument-specific credit risk which will be recognized in Other comprehensive income.

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 March 31, 2023, of 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: 5 percent—15 percent short-term rates (maturing in less than 5 years), 15 percent—25 percent medium-term rates (maturing between 5 years and 10 years, inclusive), and 70 percent—80 percent long-term rates (maturing beyond 10 years).
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 March 31, 2023, 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.

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 March 31, 2023, 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$255 $373 $665 $791 $736 $610 
Claims at 100% immediate mortality149 158 154 146 132 118 

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$1,010 $1,370 $1,973 $2,414 $2,799 $3,024 

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$45 $55 $66 $77 $85 $92 
GLB net amount at risk399 498 621 746 868 881 
Claims at 100% immediate mortality32 32 32 31 31 31 

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 March 31, 2023. 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.
On July 1, 2022, we acquired the personal accident, supplemental health, and life insurance business of Cigna in several Asian markets (Cigna Asia business). As of and for the three months ended March 31, 2023, Cigna's Asia business represented approximately 7 percent of consolidated revenues and 3 percent of total assets. We currently exclude, and are in the process of working to incorporate, Cigna's Asia business in our evaluation of internal controls over financial reporting, and related disclosure controls and procedures.
Other than working to incorporate Cigna's Asia business as noted above, there have been no changes in Chubb's internal controls over financial reporting during the three months ended March 31, 2023, that have materially affected, or are reasonably likely to materially affect, Chubb's internal controls over financial reporting.
