Chubb Business Summary

Chubb Limited (CB) operates as the world’s largest publicly traded property and casualty (P&C) insurance company, generating revenue primarily through insurance premiums and net investment income from its $171 billion asset portfolio. The company’s high-density business model is organized into six primary segments: North America Commercial P&C, North America Personal P&C, North America Agricultural Insurance (where it is the top U.S. crop insurer), Overseas General, Global Reinsurance, and Life Insurance. Chubb distinguishes itself through disciplined underwriting and a diverse global footprint spanning 54 countries, catering to multinational corporations, small businesses, and high-net-worth individuals. In the competitive landscape, Chubb contends with global giants such as Allianz, AXA, American International Group (AIG), and The Travelers Companies, maintaining a dominant market position characterized by industry-leading combined ratios and a specialized focus on complex commercial risks and premium personal lines. Originally founded in 1882 by Thomas Caldecot Chubb and his son Percy, the modern entity was solidified through the 2016 merger with ACE Limited. The leadership team is anchored by Chairman and CEO Evan G. Greenberg, who has led the company since 2004 and carries a deep industry pedigree as the son of former AIG chief Maurice Greenberg. Key executives include John Keogh (President and COO), Peter Enns (Executive VP and CFO), and Julie Dillman, who serves as the Executive Chairperson for Operations, Technology, and Digital Transformation, overseeing the firm’s modernization and AI integration. The board is led by Independent Lead Director Michael P. Connors, with notable oversight from directors such as former Citigroup CEO Michael L. Corbat. Chubb’s institutional credibility is reinforced by significant backing from major investors, including a high-profile stake held by Berkshire Hathaway, alongside traditional heavyweights like Vanguard and BlackRock.
