Chubb Limited is a global insurance and reinsurance organization headquartered in Zurich, Switzerland, that serves a diverse client base across 54 countries and territories. The company provides commercial and consumer property and casualty (P&C) insurance, accident and health (A&H) coverage, reinsurance, and life insurance products. As of December 31, 2025, Chubb reported total assets of $272 billion and shareholders’ equity of $74 billion. Its operations encompass risk management, loss control, engineering, and specialized lines such as directors and officers, aviation, energy, and surety. Chubb emphasizes underwriting discipline, seeking to earn profits through prudent risk selection rather than pursuing volume for its own sake.

Chubb generates revenue primarily from three sources: P&C underwriting income, investment income, and life segment income. In 2025, consolidated net premiums earned amounted to $53.0 billion, reflecting premiums collected from its broad portfolio of insurance contracts. Investment income is derived from a disciplined, investment‑grade fixed‑income portfolio supplemented by limited partnerships and funds, with a focus on maintaining liquidity and credit quality. Life segment income includes both insurance contract earnings from mortality and morbidity risks and investment contract fees from policyholder deposits. Together, these streams drive the company’s profitability and support its capital‑return objectives.

The company operates through the following 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.

• North America Commercial P&C Insurance: provides P&C and A&H insurance and services to large, middle‑market, and small commercial businesses in the U. S., Canada, and Bermuda. This segment includes commercial insurance, major accounts, wholesale specialty, and Bermuda high‑excess lines, each targeting distinct client groups and risk profiles.

• North America Personal P&C Insurance: offers homeowners, automobile, valuable articles, personal excess liability, travel, cyber, and recreational marine insurance to affluent and high‑net‑worth individuals and families in the U. S. and Canada. The segment focuses on high‑value personal lines that exceed the capabilities of mass‑market carriers.

• North America Agricultural Insurance: delivers crop insurance, primarily Multiple Peril Crop Insurance and crop‑hail, through Rain and Hail, and farm‑and‑ranch specialty P&C coverages via the Chubb Agribusiness unit in the U. S. and Canada. It also supplies commercial agribusiness coverages for companies that manufacture, process, or distribute agricultural products.

• Overseas General Insurance: encompasses Chubb International’s retail commercial and consumer lines, the wholesale specialty business of Chubb Global Markets, and the international supplemental A&H business. Operations span Europe, the Middle East and Africa, Asia, and Latin America, offering both admitted and surplus‑lines products through brokers, agents, and digital platforms.

• Global Reinsurance: provides traditional and non‑traditional reinsurance coverage worldwide through Chubb Tempest Re units in Bermuda, the USA, International, and Canada. The segment focuses on property catastrophe, casualty, and specialty lines, leveraging Chubb’s capital strength and analytical capabilities to serve primary insurers.

• Life Insurance: comprises international life operations (Chubb Life), including Huatai Life, Chubb Life Re, and Chubb Benefits, offering protection and savings products such as term life, universal, unit‑linked, annuities, and asset management services. The segment’s core markets are in Asia, with additional presence in Egypt and select Latin American countries through joint distribution models.

Chubb ranks among the largest global property and casualty insurers, distinguished by its diversified product mix, strong capital base, and consistent underwriting discipline. The company competes with major multinational insurers such as Allianz, AXA, Zurich Insurance Group, and Berkshire Hathaway, as well as regional players and Lloyd’s syndicates in specific lines. Its competitive advantages include sophisticated risk selection, a reputation for superior claims service, a global platform that enables multinational account servicing, and the ability to offer integrated P&C, A&H, and life solutions. This breadth of offerings and geographic reach provides stability across market cycles and supports long‑term book‑value growth.

Chubb serves multinational corporations, mid‑size and small businesses, affluent and high‑net‑worth individuals, and consumers purchasing personal lines such as homeowners and automobile coverage. The company also supplies accident and health programs to employers and affinity groups, and provides reinsurance to primary insurers seeking capacity protection. Its client base spans a wide range of industries, including construction, manufacturing, technology, finance, and healthcare, reflecting Chubb’s ability to tailor solutions to varied risk profiles.
