Chubb Limited (NYSE: CB) is a major global insurer and reinsurer providing property and casualty (P&C), accident and health, reinsurance, and life insurance products. The company’s core operations are organized around insurance and reinsurance needs across geographies and customer segments. In North America, Chubb serves businesses through its Commercial Property & Casualty division with offerings such as commercial property, casualty, workers’ compensation, package policies, risk management services, financial lines, marine, construction, environmental, medical/cyber risk solutions, surety, and excess casualty. It also serves affluent individuals and high-net-worth families through Personal P&C, covering homeowners, automobiles (including collector vehicles), valuable possessions, and various liability and travel/recreational marine risks.
For agricultural customers, Chubb’s North American Agricultural Insurance business focuses on protection for farms and ranch properties and multi-peril crop and crop-hail coverage—product design aimed at aligning insurance coverage to seasonal and weather-related risk. Internationally, the Overseas General Insurance segment provides traditional P&C coverage and specialized lines such as financial lines, marine, energy, aviation, political risk, and construction, with products often delivered to corporate and mid-market clients and smaller customers through retail brokers and agents.
Chubb’s Global Reinsurance segment, operating under the Chubb Tempest Re brand, provides both traditional and specialty reinsurance to P&C insurers worldwide. In addition, Chubb’s Life Insurance division offers protection and savings products including whole life, endowment plans, individual and group term life, medical and health, personal accident, credit life, universal life, and unit-linked contracts.
From a business model perspective, Chubb’s revenue is largely driven by insurance premiums, which are supported by underwriting discipline and, for many insurers, investment income. A key cost driver is claims and expenses (including severity and frequency of losses, catastrophe risk such as weather-related events, and claims handling). Capital and solvency management are central to sustaining growth and paying claims—reflected in industry metrics like leverage and liquidity, alongside operational expenses (e.g., sales and general administrative costs). Because insurers do not have a traditional “bill of materials” in the manufacturing sense, the practical analog for cost structure is the underwriting/claims expense stack: policy administration, broker/agent-related expenses, claims management, reinsurance costs, and investment-related operating costs.
Financially, the company is typically evaluated through underwriting performance, combined ratios (for P&C), premium growth, investment yield, and return on equity and assets. Key leadership includes Chairman and CEO Evan G. Greenberg, who guides strategy and oversight across lines of business. Overall, Chubb’s stated mission is to help protect what matters most by underwriting a wide range of risks with a focus on breadth of coverage, specialty capabilities, and global distribution.
