Analogy 1: The Goldman Sachs of insurance.

Analogy 2: Like AIG or Travelers, but specializing in bespoke insurance for businesses and high-net-worth individuals.

• Commercial Property & Casualty Insurance: Protects businesses from property damage, liability claims, workers' compensation, and other operational risks.
• Personal Property & Casualty Insurance: Offers tailored insurance solutions for high-net-worth individuals and families, covering homes, vehicles, valuable possessions, and personal liability.
• Accident & Health Insurance: Provides coverage for medical expenses, disability income, and accidental death benefits for individuals and employee groups.
• Reinsurance: Sells insurance to other insurance companies to help them reduce their risk exposure and capacity.

Chubb Limited (symbol: CB) is a global insurance company. While it serves a broad spectrum of clients, its commercial property & casualty business represents its largest segment by premium volume, indicating it primarily sells to other companies.

Due to the nature of the insurance business, Chubb has millions of policyholders globally and does not publicly disclose the names of its specific customer companies. Insurers typically do not have "major customers" in the traditional sense of a supplier selling to a few large corporate clients. Instead, they serve broad categories of businesses across various industries.

Chubb's major customer categories in the business sector include:

• Large Corporations and Multinational Companies: Chubb provides a wide array of property, casualty, and specialty insurance solutions for complex risks faced by large enterprises operating globally.
• Middle Market Companies: Serving businesses that fall between small enterprises and large corporations, Chubb offers comprehensive insurance products tailored to their specific industry and risk profiles.
• Small Businesses: Chubb also provides essential property, liability, and workers' compensation coverage for small and growing businesses.
• Specialty Sectors: The company offers highly specialized insurance products for industries such as energy, marine, aviation, technology, financial institutions, and construction, among others.

While the primary focus based on premium volume is on businesses, it's worth noting that Chubb also has a significant presence in personal lines, particularly serving affluent and high-net-worth individuals and families with customized home, auto, and valuable article insurance.
