Chubb Limited — Business Overview
What does Chubb do?
Chubb is one of the world's largest property and casualty (P&C) insurers, selling a broad range of insurance and reinsurance products to businesses and individuals in 54 countries. It collects premiums from policyholders in exchange for agreeing to cover losses from events like fires, lawsuits, natural disasters, accidents, and death. The company generated $53.0 billion in net premiums earned (NPE) — the portion of premiums it keeps after paying reinsurers — in 2025, with $272 billion in total assets and $74 billion in shareholders' equity.
Chubb operates through six segments:
| Segment | Share of 2025 NPE | What it does |
|---|---|---|
| North America Commercial P&C Insurance | 38% | P&C and accident & health (A&H) insurance for large corporations, mid-size, and small businesses in the U.S., Canada, and Bermuda |
| North America Personal P&C Insurance | 13% | Home, auto, valuables, and liability insurance for affluent and high-net-worth individuals in the U.S. and Canada |
| North America Agricultural Insurance | 5% | Federally subsidized crop insurance and farm/ranch P&C coverage in the U.S. and Canada |
| Overseas General Insurance | 27% | Commercial and consumer P&C, specialty lines, and A&H insurance across international markets, including China |
| Global Reinsurance | 3% | Reinsurance (insurance sold to other insurers) worldwide under the Chubb Tempest Re brand |
| Life Insurance | 14% | Life, accident, health, and savings products, primarily in Asia; also includes Chinese asset management operations through Huatai |
How does Chubb make money?
Chubb earns money from three main sources: underwriting profit, investment income, and life segment income. Underwriting profit is what remains after paying claims and operating expenses out of the premiums collected. This is Chubb's core focus — it describes itself explicitly as "an underwriting company" that prioritizes disciplined pricing and risk selection over volume. Investment income is earned by putting the float (premiums collected but not yet paid out as claims) to work in a portfolio of primarily investment-grade fixed-income securities. The Life segment generates income through insurance premiums, investment spreads on policyholder savings balances, and asset management fees.
A notable revenue stream within its Life and China operations is asset management. Huatai Asset Management, Chubb's majority-owned Chinese subsidiary, manages over $155 billion in assets under management (AUM), more than 90% of which belongs to third-party clients. It earns management and performance fees on those assets, adding a fee-based income layer that is less common among pure-play insurers.
What market does Chubb operate in?
Chubb operates in the global insurance and reinsurance market, which is large, mature in developed economies, and still growing in emerging markets. P&C insurance is a cyclical industry, meaning that pricing and profitability swing based on the supply of capital and the frequency of large losses. Chubb addresses this by writing a mix of less cyclical product lines and maintaining strict underwriting discipline across market cycles.
Several secular trends shape this industry. Climate change is increasing the frequency and severity of natural catastrophes — a direct risk to P&C insurers. Chubb explicitly acknowledges this in its underwriting process and has reduced exposure in wildfire-prone areas. On the other side, growing wealth in Asia is driving demand for life, health, and personal insurance products, which is why Chubb has invested heavily in that region through acquisitions like Cigna's Asian business in 2022 and a controlling stake in China's Huatai Group (now approximately 87.2% owned) in 2023.
Who are Chubb's main competitors?
The competitive landscape varies significantly by segment and geography, with no single dominant rival across all of Chubb's businesses. In North America commercial lines, it faces large national carriers as well as mid-size specialty insurers. In major accounts and global specialty, competitors include large global carriers and Lloyd's of London syndicates. In Asia life insurance, it competes against multinational insurers, large domestic carriers, and state-owned Chinese insurers. The reinsurance segment faces competition from major global reinsurers as well as alternative capital providers (such as catastrophe bonds) that have grown in recent years.
Chubb's stated competitive advantages center on product breadth, geographic scale, underwriting expertise, and claims service quality. It is one of the few insurers capable of writing policies on a locally admitted basis (meaning through licensed local entities rather than across borders) in virtually every major insurance market. This matters especially for large multinational corporations that need consistent coverage across many countries. Its strong capital base also allows it to take on large and complex risks that smaller competitors cannot.
Where does Chubb operate?
Chubb has a genuinely global footprint, with operations in 54 countries, and its workforce is more international than its U.S. listing might suggest. Of its approximately 45,000 employees, 40% are based in Asia, 37% in North America, 13% in Latin America, and 10% in Europe, Eurasia, and Africa.
Asia is a critical and growing region for the company. The Life Insurance segment derives 95% of its net written premiums from Asia, with key markets in South Korea, mainland China, Hong Kong, Taiwan, Thailand, Vietnam, New Zealand, and Indonesia. China in particular represents a significant and growing exposure through Huatai Group, which includes P&C, life, and asset management businesses operating across 20–28 Chinese provinces. This concentration carries geopolitical risk that the filing implicitly acknowledges through its discussion of local regulatory requirements, foreign ownership rules, and the use of joint ventures to comply with Chinese law. Chubb both underwrites and sells insurance in its international markets through locally licensed entities, giving it a compliance and distribution advantage, but also tying its results to the regulatory and economic conditions of those countries.
