Rewritten

[removed: Although we attempt to manage our exposure to such events through the use of underwriting controls, risk models, and the purchase of third-party reinsurance, catastrophic] [added: Catastrophic] events are inherently unpredictable and the actual nature of such events, when they occur, could be more frequent or severe than contemplated in our pricing and risk management expectations.

Rewritten

At December 31, [removed: 2024,] [added: 2025,] gross A&E liabilities represented approximately [removed: 1.6] [added: 1.4] percent of our gross loss reserves.

Rewritten

Accordingly, the ultimate settlement of losses, arising from either latent or non-latent causes, may be significantly greater or less than the loss and loss [added: expense reserves held at the balance sheet date.]

Rewritten

Rewritten

[removed: 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 impacts of insurance, judicial decisions, and social inflation.

Rewritten

We seek to manage our loss exposure by maintaining a disciplined underwriting process throughout our insurance [removed: operations.][added: operations, including the use of underwriting controls and risk models.]

Rewritten

Our reinsurance business also purchases retrocessional [removed: protection] [added: protection,] which allows a reinsurer to cede to another company all or part of the reinsurance originally assumed by the reinsurer.

Rewritten

At December 31, [removed: 2024,] [added: 2025,] we had [removed: $20.1] [added: $20.6] billion of reinsurance recoverables, net of reserves for uncollectible recoverables.

Rewritten

At December 31, [removed: 2024,] [added: 2025,] the aggregate reinsurance balances ceded by our active subsidiaries to Century were approximately $1.9 billion.

Rewritten

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

Rewritten

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

Rewritten

The surety business [removed: tends to be] [added: is] characterized by infrequent but potentially high severity losses.

Rewritten

[removed: In accordance with industry practice, we] [added: We] generally pay amounts owed on claims to brokers who, in turn, remit these amounts to the insured or ceding insurer.

Rewritten

[added: 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

[removed: In addition, a lack of credit] available to our customers could impact our ability to collateralize this risk to our satisfaction, which in turn, could reduce the amount of high-deductible policies we could offer.

Rewritten

Our investment assets are invested by professional investment management firms under the direction of our management team in accordance with investment guidelines approved by the [removed: Risk & Finance Committee of the Board of Directors.][added: Board.]

Rewritten

[removed: Although our investment guidelines stress diversification of risks and conservation of principal and liquidity, our] [added: Our] investments are subject to market risks and risks inherent in individual securities.

Rewritten

[removed: Although we take measures to manage the risks of investing in a changing interest rate environment, we] [added: We] may not be able to effectively mitigate interest rate sensitivity.

Rewritten

[removed: As stated, our] [added: Our] fixed income portfolio is primarily invested in high quality, investment-grade securities.

Rewritten

However, a smaller portion of the portfolio, approximately 17 percent at December 31, [removed: 2024,] [added: 2025,] is invested in below investment-grade securities.

Rewritten

[removed: While we have put in place procedures to monitor the credit risk and liquidity of our invested assets, it] [added: It] is possible [removed: that,] [added: that] in periods of economic weakness (such as recession), we may experience credit or default losses in our portfolio, which could adversely affect our results of operations and financial condition.

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 [added: of our Common Shares.]

Rewritten

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

Rewritten

[removed: 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, although, to the extent permitted by Swiss law, exemptions from the 10 percent limit apply for repurchased treasury shares dedicated for cancellation under our shareholder-approved capital band [removed: or] [added: and] for shares acquired pursuant to a shareholder-ratified repurchase program and dedicated for cancellation.

Rewritten

The principal currencies creating foreign exchange risk are the Korean won, Chinese yuan renminbi, Canadian dollar, Australian dollar, Mexican peso, [removed: British pound sterling,] [added: Thai baht,] Hong Kong dollar, [removed: Thai baht,] [added: Brazilian real,] New [removed: Taiwan] [added: Zealand] dollar, and euro.

Rewritten

At December 31, [removed: 2024,] [added: 2025,] approximately [removed: 29.9] [added: 26.7] percent of our unhedged net assets were denominated in foreign currencies.

Rewritten

[removed: The laws and] [added: Applicable statutes,] regulations [removed: of the jurisdictions in which our insurance] and [removed: reinsurance subsidiaries are domiciled] [added: policies] require, among other things, maintenance of minimum levels of statutory capital, surplus, and liquidity, various solvency standards, and periodic examinations of subsidiaries' financial condition.

Rewritten

[removed: The IAIS has developed a Common Framework for the Supervision of Internationally Active Insurance Groups] (ComFrame), which is focused on the effective group-wide supervision of international active insurance groups (IAIGs), such as Chubb.

Rewritten

Chubb also receives requests for information from investors, customers and other stakeholders from time [added: to time on various aspects of its policies and strategies relating to climate change.]

Rewritten

This has resulted in expanded and increasingly complex expectations related to reporting under multiple, [removed: various,] disparate and potentially inconsistent reporting requirements, increased due diligence, and potential requirements for the reporting of scope 3 greenhouse gas emissions.

Rewritten

New reporting standards, regulations and requirements with various aims and goals could expose us to legal, regulatory, investor and other stakeholder scrutiny, and customers that disagree with our actions [removed: or reporting on climate change] may determine not to do business with us, all of which may adversely affect our business, reputation and results of operations.

Rewritten

Both current and future foreign operations could be adversely affected by unfavorable geopolitical developments, including law changes; tax changes; changes in trade policies; changes to visa or immigration policies; regulatory restrictions; government leadership changes; political events and upheaval; sociopolitical instability; [removed: social, political or economic instability resulting from climate change;] and nationalization of our [added: operations without compensation.]

Rewritten

[removed: Like all global companies, our] [added: Our] systems and those of our third-party service providers, have been, and will likely continue to be, targeted by or subject to viruses, malware or other malicious codes, unauthorized access, cyber-attacks, cyber frauds, ransomware or other unauthorized occurrences, on or conducted through our information systems, which jeopardize the confidentiality, integrity or availability of our information or information systems.

Rewritten

[removed: Although we have implemented] [added: The] administrative and technical controls and [removed: have taken] protective actions [added: we have taken (including conducting due diligence security reviews and negotiating agreements with third-party service providers), which are] designed to reduce the risk of cyber incidents and to protect our information technology and assets, [removed: including conducting due diligence security reviews and negotiating agreements with third-party service providers, and we additionally endeavor to modify such procedures and agreements as circumstances warrant, such measures] may be insufficient to prevent cybersecurity events, which may include unauthorized access, computer viruses, malware or other malicious code or cyber-attack, ransomware, phishing scams, or similar attempts to fraudulently induce our [removed: employees] [added: employees, third party vendors] or others to take actions that compromise our information or information systems, business compromise attacks, catastrophic events, system failures and disruptions, employee errors, negligence or malfeasance, loss of assets or data and other events that could have security consequences.

Rewritten

[removed: Despite the contingency plans and facilities we have in place and our efforts to observe the regulatory requirements surrounding information security, our] [added: Our] ability to conduct business may be adversely affected by a disruption of the infrastructure that supports our business in the communities in which we are located, or of outsourced services or functions.

Rewritten

The modeled outputs and related analyses are subject to various assumptions, uncertainties, model errors and the inherent limitations of any statistical analysis, including the use of historical internal and [added: industry data.]

Rewritten

It is not always possible to deter or prevent [removed: employee] [added: employee, agent, broker or vendor] misconduct, and the precautions that we take to prevent and detect this activity may not be effective in all cases.

Rewritten

We compete on an international and regional basis with major U.S., [removed: Bermuda,] [added: Bermudian,] European, and other international insurers and reinsurers and with underwriting syndicates, some of which have greater financial, technological, marketing, distribution and management resources than we do.

Rewritten

We will be at a competitive disadvantage [removed: if, over time,] [added: if] our competitors are more effective than us in their utilization of technology and evolving data analytics.

Rewritten

[removed: If we do] not anticipate or keep pace with these technological and other changes impacting the insurance industry, it could adversely affect our business results of operations and financial condition.

New in FY2025

The amount of capital that our insurance subsidiaries have and must hold to maintain their financial strength and credit ratings and meet other requirements can vary significantly from time to time and is sensitive to a number of factors, some of which are outside of our control.

New in FY2025

Capital requirements for our insurance subsidiaries are prescribed by the applicable insurance regulators, while rating agencies establish requirements that inform ratings for our insurance subsidiaries.

New in FY2025

Projecting surplus and the related capital requirements is complex and requires making assumptions regarding how our business will perform within the broader macroeconomic environment.

New in FY2025

Insurance regulators and rating agencies evaluate company capital through financial models that calculate minimum capitalization requirements based on risk-based capital formulas for property and casualty insurance groups and their subsidiaries.

New in FY2025

In any particular year, capital levels and risk-based capital requirements may increase or decrease depending on a variety of factors including the mix of business written by our insurance subsidiaries and correlation or diversification in the business profile, the amount of additional capital our insurance subsidiaries must hold to support business growth, the value of securities in our investment portfolio, changes in interest rates and foreign currency exchange rates, as well as changes to the regulatory and rating agency models used to determine our required capital.

Our insurance and reinsurance subsidiaries conduct business globally and are subject to varying degrees of supervision and regulation by the regulatory authorities under which they conduct business.

New in FY2025

The extent of regulation on our insurance business varies across the jurisdictions where we operate, but generally is governed by laws that delegate regulatory, supervisory and administrative authority to insurance departments and similar regulatory agencies.

New in FY2025

The laws and regulations of the jurisdictions in which our insurance and reinsurance subsidiaries are domiciled generally grant regulatory agencies and/or self-regulatory organizations broad rulemaking and enforcement powers, including the power to regulate the issuance, marketing, sale and distribution of our products, the manner in which we underwrite our policies, the delivery of our services, the nature or extent of disclosures that we give our customers, the compensation of our distribution partners, the manner in which we handle claims on our policies and the administration of our policies and contracts, as well as the power to limit or restrict our business for failure to comply with applicable laws and regulations.

Dropped from FY2024

On August 16, 2022, President Biden signed the Inflation Reduction Act (IRA) of 2022 (H.R. 5376).

Dropped from FY2024

Key tax provisions included in the Inflation Reduction Act include a 15 percent corporate alternative minimum tax (CAMT) on adjusted financial statement income for corporations with average profits over $1 billion, and a 1 percent excise tax on repurchases of corporate stock.

Dropped from FY2024

The CAMT and the excise tax on share repurchases are effective for tax years beginning after December 31, 2022.

Dropped from FY2024

Since enactment, the IRS and U.S. Treasury Department have issued final and proposed regulations and notices, interpreting and implementing the new provisions.

On January 20, 2025, President Trump issued a memorandum announcing that the OECD framework has “no force or effect in the United States” and disavowing any commitments previously made by the United States with respect to the framework.

Dropped from FY2024

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.

Dropped from FY2024

Several multilateral organizations, including the EU and the OECD have, in recent years, expressed concern about some countries not participating in adequate tax information exchange arrangements and have threatened those that do not agree to cooperate with punitive sanctions by member countries.

It is still unclear what all these sanctions might be, which countries might adopt them, and when or if they might be imposed.

Dropped from FY2024

We cannot provide assurance that the Tax Information Exchange Agreements (TIEAs) that have been entered into by Switzerland and Bermuda will be sufficient to preclude the sanctions described above, which, if ultimately adopted, could adversely affect us.

Our loss reserves comprise approximately [removed: 77] [added: 76] percent casualty-related business, which typically encompasses long-tail risks, and other risks where a high degree of judgment is required.

Rewritten

While we believe that our reserve for unpaid losses and loss expenses at December 31, [removed: 2024,] [added: 2025,] 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.

Specifically, for our main U.S. Excess/Umbrella portfolios, a five percentage point change in the tail factor (e.g., 1.10 changed to either 1.15 or 1.05) would cause a change of approximately [removed: $0.8] [added: $0.9] billion, either positive or negative, for the projected net loss and loss expense reserves.

Overview

Dropped from FY2024

We operate 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.

Dropped from FY2024

For more information on our segments refer to “Segment Information” under Item 1.

Dropped from FY2024

We have grown our business through increased premium volume, expansion of product offerings and geographic reach, and acquisitions of other companies.

Dropped from FY2024

Our product and geographic diversification differentiate us from the vast majority of our competitors and has been a source of stability during periods of industry volatility.

Dropped from FY2024

Our long-term business strategy focuses on sustained growth in book value achieved through a combination of underwriting and investment income.

Dropped from FY2024

By doing so, we provide value to our clients and shareholders through use of our substantial capital base in the insurance and reinsurance markets.

Dropped from FY2024

We are organized along a profit center structure by line of business and territory that does not necessarily correspond to corporate legal entities.

Dropped from FY2024

Profit centers can access various legal entities subject to licensing and other regulatory rules.

Dropped from FY2024

Profit centers are expected to generate P&C underwriting income, life segment income, and appropriate risk-adjusted returns.

Dropped from FY2024

Our corporate structure has facilitated the development of management talent by giving each profit center's senior management team the necessary autonomy within underwriting authorities to make operating decisions and create products and coverages needed by its target customer base.

Dropped from FY2024

We are focused on delivering P&C underwriting profit and life segment income by only writing policies which we believe adequately compensate us for the risk we accept.

Dropped from FY2024

We generate gross revenues from three principal sources: P&C income, Life income, and investment income.

Dropped from FY2024

Invested assets are substantially held in liquid, investment grade fixed income securities of relatively short duration.

Dropped from FY2024

Claims payments in any short-term period are highly unpredictable due to the random nature of loss events and the timing of claims awards or settlements.

Dropped from FY2024

The value of investments held to pay future claims is subject to market forces such as the level of interest rates, stock market volatility, and credit events such as corporate defaults.

Dropped from FY2024

The actual cost of claims is also volatile based on loss trends, inflation rates, court awards, and catastrophes.

Dropped from FY2024

We believe that our cash balance, our highly liquid investments, credit facilities, and reinsurance protection provide sufficient liquidity to meet unforeseen claim demands that might occur in the year ahead.

Outlook

Dropped from FY2024

2024 was a simply outstanding year, as our results, top and bottom line, continue to demonstrate the broad and diversified nature of our company and the consistency of contributions from our businesses around the world: North America, Asia, Europe, Latin America, both commercial and consumer.

Dropped from FY2024

As we look forward to 2025, we have good momentum and are optimistic about the year ahead.

Dropped from FY2024

The recent California wildfire disaster, which is a first quarter 2025 event, has an estimated net pre-tax cost of $1.5 billion and highlights our commitment to supporting our policyholders in times of need.

Dropped from FY2024

Despite this, we expect continued strong performance across all business segments.

Dropped from FY2024

Global P&C market conditions remain favorable, with significant growth opportunities across our operations, including commercial and consumer lines.

Dropped from FY2024

We anticipate robust growth in operating earnings and earnings per share, driven by our key sources of income: P&C underwriting, investment income, and life insurance.

Dropped from FY2024

While we acknowledge the challenges posed by natural disasters, we are well-positioned to continue delivering outstanding results in 2025.

PART I

Dropped from FY2024

opinion, no material part of our business is dependent upon a single insured or group of insureds.

Dropped from FY2024

We do not believe that the loss of any one insured would have a material adverse effect on our financial condition or results of operations.

Dropped from FY2024

Competition

Dropped from FY2024

Competition in the insurance and reinsurance marketplace is substantial.

Dropped from FY2024

We compete on an international and regional basis with major U.S., Bermuda, European, and other international insurers and reinsurers and with underwriting syndicates, some of which have greater financial, technological, marketing, distribution and management resources than we do.

Dropped from FY2024

In addition, capital market participants have created alternative products that are intended to compete with reinsurance products.

Dropped from FY2024

We also compete with new companies and existing companies that move into the insurance and reinsurance markets.

Dropped from FY2024

Competitors include other stock companies, mutual companies, alternative risk sharing groups (such as group captives and catastrophe pools), and other underwriting organizations.

Dropped from FY2024

Competitors sell through various distribution channels and business models, across a broad array of product lines, and with a high level of variation regarding geographic, marketing, and customer segmentation.

Dropped from FY2024

We compete for business not only on the basis of price but also on the basis of availability of coverage desired by customers and quality of service.

Dropped from FY2024

We also compete in China for assets under management (AUM) with investment management firms, banks, and other financial institutions that offer products that are similar to those offered by Huatai's asset management companies.

Dropped from FY2024

The insurance industry is changing rapidly.

Dropped from FY2024

Our ability to compete is dependent on a number of factors, particularly our ability to maintain the appropriate financial strength ratings as assigned by independent rating agencies and effectively using digital capabilities, including the growth of new digital-based distribution models, in an everchanging competitive landscape and incorporating, among other things, climate and environmental changes into our insurance processes, products, and services.

Dropped from FY2024

Trademarks and Trade Names

Dropped from FY2024

Various trademarks and trade names we use protect names of certain products and services we offer and are important to the extent they provide goodwill and name recognition in the insurance industry.

Dropped from FY2024

We use commercially reasonable efforts to protect these proprietary rights, including various trade secret and trademark laws.

Dropped from FY2024

We intend to retain material trademark rights in perpetuity, so long as it satisfies the use and registration requirements of applicable countries.

Dropped from FY2024

One or more of the trademarks and trade names could be material to our ability to sell our products and services.

Dropped from FY2024

We have taken appropriate steps to protect our ownership of key names, and we believe it is unlikely that anyone would be able to prevent us from using names in places or circumstances material to our operations.

Dropped from FY2024

Global Workforce

Dropped from FY2024

At Chubb, our employees are central to our commitment to deliver excellence in all we do, to provide exceptional service for our customers and business partners, and to be there when our customers need us most.

Human Capital Management Measures

Dropped from FY2024

We have multiple measures of human capital management, including how well we are doing in providing opportunity for everyone to succeed:

Dropped from FY2024

- Women lead lines of business that account for 40 percent of our global premium, lead several of our key global functions (including Enterprise Risk Management, Operations and Technology, Human Resources and Communications) and hold about a third of our executive level manager roles, as well as more than 40 percent of the next most senior manager roles.

Dropped from FY2024

- Our business leaders reflect the ethnic diversity of our global footprint.

Dropped from FY2024

The most senior executives who lead the company’s largest businesses and functions come from Ecuador, Argentina, Australia, the U.K., Korea, Canada, China, Chile, South Africa, and the U.S. Within the U.S., nearly 20 percent of our executive level managers are racially diverse, as well as more than 27 percent of the next most senior managers.

Dropped from FY2024

- Investing in opportunities for personal growth and development is a key to our success.

Dropped from FY2024

These development opportunities help our employees gain exposure and experiences that empower them to grow and contribute and enable our leaders to be intentional in maximizing the potential of each team member.

Dropped from FY2024

In 2024, over 8,000 employees participated in facilitated learning programs, and close to 3,500 colleagues engaged in programs designed to enhance cultural awareness and inclusion.

Prior to the transfer of our entire held-to-maturity (HTM) portfolio to the AFS portfolio in 2023, HTM securities were evaluated for potential credit loss on a collective pool basis quarterly.

Dropped from FY2024

Chubb pooled HTM securities and calculated the current expected credit loss for each pool using Moody's corporate bond default average, corporate bond recovery rate, and an economic cycle multiplier based on the leading economic index adjusted for a forward-looking economic outlook.
