Travelers is one of the largest P&C insurance companies in the U.S., selling policies that protect businesses and individuals against financial losses from events like accidents, natural disasters, lawsuits, and theft. Travelers operates through three segments: Business Insurance (~50% of net written premiums), Bond & Specialty Insurance (~10%), and Personal Insurance (~40%). Business Insurance sells commercial P&C coverage to companies of all sizes, organized by customer scale from small "Main Street" businesses to large corporations, across product lines including commercial auto, workers' comp, general liability, and property. Bond & Specialty sells surety bonds and management liability products like D&O and cyber; Travelers is a leading surety underwriter in North America. Personal Insurance covers individual auto and homeowners policies, with roughly 8.4 million active U.S. policies. Travelers sells primarily through independent agents and brokers, which is central to its distribution strategy, with a smaller direct and digital channel in personal lines. Travelers earns money two ways: underwriting income (premiums minus claims and expenses) and investment income from the float, invested primarily in high-quality fixed income securities across an invested asset base exceeding $100B. Key profitability drivers include renewal pricing staying ahead of loss cost trends, catastrophe exposure management, and investment yield. Travelers uses reinsurance to cap catastrophe losses, with its corporate treaty attaching at $3B of losses per year. The company is investing in AI and data analytics to improve underwriting, pricing segmentation, and claims automation, and cites a proprietary dataset of over 65 billion data points as a competitive input.
