Customers and geography
The filing says Chubb serves multinational corporations, mid-size and small businesses, affluent and high-net-worth individuals, individuals purchasing life or A&H coverage, employee or member groups, and insurers seeking reinsurance.

Competition
The filing does not name specific competing companies. It describes competition from large national, global, regional, small, and mid-size insurers; U.S.-based and non-U.S. global carriers; indigenous and locally based insurers; financial institutions and bank-owned insurance subsidiaries; Lloyd’s syndicates; reinsurers; and capital-markets participants providing alternative capital. For North American commercial insurance, it also identifies self-insured retentions and captive programs as competing alternatives. The filing says competitive factors for international operations include underwriting expertise and pricing, operating efficiency, product differentiation, producer relationships, and policyholder service quality. Reinsurance demand can also be affected by government-sponsored or backed catastrophe funds.

Key risks
- Natural and man-made disasters, including terrorism, cyber-attacks, pandemics, and climate-related changes, could produce substantial losses and volatility.
- Actual claims could exceed loss reserves because reserves rely on estimates and judgments.
- Emerging claim and coverage issues could extend coverage beyond underwriting intent or increase claim frequency and severity.
- Loss-limitation methods, underwriting controls, risk models, policy provisions, and geographic limits may not limit losses as intended.
- Reinsurance or retrocessional protection may be unavailable on acceptable terms, and reinsurers may not pay.
- Life insurance reserve and market risk benefit changes can make net income and shareholders’ equity volatile.

People and operations
Chubb reported 45,000 employees for FY2025. The company says it is organized as profit centers by line of business and territory, rather than necessarily by corporate legal entity. These profit centers can access different legal entities subject to licensing and regulatory rules, and are expected to generate P&C underwriting income, life segment income, and appropriate risk-adjusted returns. The filing also states that the company enhanced employee experience in 2025 through operational platforms, self-service capabilities, and refreshed performance and development processes. It describes employee well-being, engagement, and community programs across regions.
