Item 1A. Risk Factors

95 rewritten, 33 added, 18 removed, 254 unchanged

Rewritten

We have substantial exposure to losses resulting from natural disasters, man-made catastrophes, such as terrorism or cyber-attack, and other catastrophic [removed: events, including pandemics.][added: events.]

Rewritten

[removed: Additionally, we] [added: We] cannot predict how legal, regulatory [removed: and/or] [added: or] social responses to concerns around global climate change and the resulting impact on various sectors of the economy may impact our business.

Rewritten

[removed: Exposure] [added: In addition, exposure] to cyber risk is increasing systematically due to greater digital [removed: dependence and increases] [added: dependence, which may increase] possible losses due to a catastrophic cyber event.

Rewritten

Cyber catastrophic scenarios are not bound by time or geographic limitations and cyber catastrophic perils do not have well-established definitions [removed: and] [added: or] fundamental physical properties.

Rewritten

[removed: Any such evaluation] [added: Such evaluations] could result in future changes in estimates of losses or reinsurance recoverables and would be reflected in our results of operations in the period in which the estimates are changed.

Rewritten

During the loss settlement period, which can be many years in duration for some of our lines of business, additional facts regarding individual claims and trends often will become [removed: known] [added: known,] which may result in a change in overall reserves.

Rewritten

At December 31, [removed: 2023,] [added: 2024,] gross A&E liabilities represented approximately [removed: 1.8] [added: 1.6] percent of our gross loss reserves.

Rewritten

In addition, the amount and timing of the settlement of our P&C liabilities are uncertain and our actual payments could be higher than contemplated in our loss reserves owing to the [removed: impact] [added: impacts] of insurance, judicial decisions, [removed: and/or] [added: and] social inflation.

Rewritten

For example, "reviver" legislation in certain states [removed: does allow] [added: allows] civil claims relating to molestation to be asserted against policyholders that would otherwise be barred by statutes of limitations.

Rewritten

[removed: In the case of] [added: We also look to limit] our [added: loss by using] assumed proportional reinsurance treaties, [added: in which] we seek per occurrence limitations or loss and loss expense ratio caps to limit the impact of losses ceded by the client.

Rewritten

We [removed: also] [added: further] seek to limit our loss exposure by geographic diversification.

Rewritten

However, there are inherent limitations in all of these tactics, and no assurance can be given against the possibility of an event or series of events that [removed: could] result in loss levels that [removed: could] have an adverse effect on our financial condition or results of operations.

Rewritten

Additionally, various provisions of our policies, [added: negotiated to limit our risks,] such as limitations or exclusions from coverage [removed: or] [added: and] choice of forum [removed: negotiated to limit our risks,] may not be enforceable in the manner we intend.

Rewritten

We may be unable to purchase reinsurance, [removed: and/or] [added: or] if we successfully purchase reinsurance, we are subject to the possibility of non-payment.

Rewritten

We purchase protection from third [removed: parties including, but not limited to, reinsurance] [added: parties, including reinsurance,] to protect against catastrophes and other sources of volatility, to increase the amount of protection we can provide our clients, and as part of our overall risk management strategy.

Rewritten

At December 31, [removed: 2023,] [added: 2024,] we had [removed: $20.2] [added: $20.1] billion of reinsurance recoverables, net of reserves for uncollectible recoverables.

Rewritten

At December 31, [removed: 2023,] [added: 2024,] the aggregate reinsurance balances ceded by our active subsidiaries to Century were approximately [removed: $1.8] [added: $1.9] billion.

Rewritten

Should Century's loss reserves experience adverse development in the future and should Century be placed into rehabilitation or liquidation, the reinsurance recoverables due from Century to its affiliates [removed: would] [added: could] be payable only after the payment in full of third-party expenses and liabilities, including administrative expenses [added: and direct policy liabilities.]

Rewritten

Thus, the intercompany reinsurance recoverables [removed: would] [added: could] be at risk to the extent of the shortage of [removed: assets remaining to pay these recoverables.]

Rewritten

While we believe the intercompany reinsurance recoverables from Century are not impaired at this time, we cannot [removed: assure] [added: provide assurance] that adverse development with respect to Century's loss reserves, if manifested, will not result in Century's [added: rehabilitation or] insolvency, which could result in our recognizing a [removed: loss to the extent of any uncollectible reinsurance from Century.][added: loss.]

Rewritten

Our net income and [removed: Shareholders'] [added: shareholders'] equity may be volatile because certain products sold by our life insurance businesses [removed: expose] [added: expose] us to future policy benefit (FPB) reserve and market risk benefits changes that are directly affected by market and other factors and assumptions.

Rewritten

Our pricing, establishment of liabilities for life insurance and annuity products, including reinsurance programs, are based upon various assumptions, including [removed: but not limited to] equity market changes, interest rates, mortality rates, morbidity rates, and policyholder behavior.

Rewritten

[removed: With the adoption of] [added: Under] long-duration targeted improvements (LDTI), the accounting for our FPB reserves is also sensitive to changing interest rate conditions.

Rewritten

We have exposure to counterparties through a variety of commercial transactions and arrangements, including reinsurance [removed: transactions;] [added: transactions,] agreements with banks, hedge funds and other investment [removed: vehicles;] [added: vehicles,] and derivative transactions, that expose us to credit risk in the event our counterparty fails to perform its obligations.

Rewritten

Under the terms of certain high-deductible policies [removed: which] [added: that] we offer, such as workers’ compensation and general liability, our customers are responsible [removed: to reimburse] [added: for reimbursing] us for an agreed-upon dollar amount per claim.

Rewritten

[removed: through collateral agreements and maintain a provision for uncollectible accounts associated with this credit exposure, an] increased inability of customers to reimburse us in this context could have an adverse effect on our financial condition and results of operations.

Rewritten

Accordingly, our business is dependent on the willingness of these agents and brokers to recommend our products to their customers, [removed: who] [added: and our agents and brokers] may also promote and distribute the products of our competitors.

Rewritten

Realized and unrealized losses in our investment portfolio would reduce our book value, and if [removed: significant,] [added: material,] can affect our ability to conduct business.

Rewritten

However, a smaller portion of the portfolio, approximately 17 percent at December 31, [removed: 2023,] [added: 2024,] is invested in below investment-grade securities.

Rewritten

We may need to raise additional funds through financings or access funds through existing or new credit facilities or through short-term repurchase [removed: agreements.][added: or borrowing arrangements.]

Rewritten

In the case of equity financings, dilution to our shareholders could result, and in any case, such securities may have rights, preferences, and privileges that are senior to those [removed: of our Common]

Rewritten

Our ability to pay dividends [removed: and/or] [added: and] to make payments on indebtedness may be constrained by our holding company structure.

Rewritten

Rewritten

In addition, Swiss law requires that the total par value of Chubb's treasury shares must not be in excess of 10 percent of its total share capital, [removed: although an exemption] [added: although, to the extent permitted by Swiss law, exemptions] from the 10 percent limit [removed: applies] [added: apply] for repurchased treasury shares dedicated for cancellation [removed: and] [added: under our shareholder-approved capital band or for shares] acquired pursuant to a shareholder-ratified repurchase [removed: program.][added: program and dedicated for cancellation.]

Rewritten

As a result, in order to maintain our share repurchase program, our shareholders must [added: either] periodically approve [removed: a reduction in] our [removed: share] capital [removed: through the cancellation of designated blocks of repurchased shares held in treasury and may from time] [added: band authorizing our Board] to [removed: time] [added: reduce our share capital or,] as necessary, [removed: in a separate vote,] ratify our share repurchase [removed: program.][added: program authorizing our Board to acquire shares in excess of the 10 percent limit.]

Rewritten

Rewritten

The memorandum also directs the U.S. Secretary of the Treasury to develop and present to President Trump a list of protective measures or other options towards foreign countries that are either not in compliance with any tax treaty with the United States or have tax rules that are “extraterritorial or disproportionately affect American companies.” The possible uneven enactment of the OECD framework by various jurisdictions coupled with the United States’ response to these rules could cause uncertainties to and increases in our income taxes.

Our loss reserves comprise approximately [removed: 78] [added: 77] percent casualty-related business, which typically encompasses long-tail risks, and other risks where a high degree of judgment is required.

Rewritten

The process of establishing loss reserves for property and casualty claims can be complex and is subject to considerable uncertainty as it requires the use of informed estimates and judgments based on circumstances underlying the insured losses [removed: known at the date of accrual.]

Rewritten

The effects of [removed: recent heightened] inflation create additional uncertainty, while climate change could, over time, add new uncertainties to the loss reserving process.

The judgments involved in projecting the ultimate losses may pertain to the use and interpretation of various standard actuarial reserving methods that place reliance on the extrapolation of actual historical data, loss development patterns, industry data, and other [removed: benchmarks] [added: benchmarks,] as appropriate.

Rewritten

While we believe that our reserve for unpaid losses and loss expenses at December 31, [removed: 2023,] [added: 2024,] is adequate, new information or emerging trends that differ from our assumptions may lead to future development of losses and loss expenses that is significantly greater or less than the recorded reserve, which could have a material effect on future operating results.

New in FY2024
