What Chubb Limited told the SEC could break it.
Chubb's disclosures map to its distinct insurance segments rather than a single theme. Its life business is geographically concentrated, with Chubb Life's operations centered in Asia — 95% of its net written premiums, deposits, and earnings — across markets like South Korea, mainland China, Hong Kong, and Taiwan. On the casualty side, its legacy asbestos-and-environmental reserves are sensitive to the legal environment: run-off subsidiary Century held about $1.5 billion of gross reserves at year-end 2025, and 'reviver' statutes reopening time-barred sexual-molestation claims could add to them. Two further exposures hinge on federal programs — its crop (MPCI) business runs through the USDA program and tracks commodity prices, and its terrorism coverage relies on the TRIA backstop, extended through December 31, 2027.
4 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Geographic concentration
- Chubb Life concentrated in Asia (95% of NWP/deposits/earnings); China Huatai stakesmedium
Chubb Life's main operations are in Asia, which accounts for 95% of its net written premiums, deposits and earnings (markets include South Korea, mainland China, Hong Kong, Taiwan, Thailand, Vietnam, New Zealand, Indonesia), with China stakes including Huatai Baoxing Fund Management (74.1%) — concentrating life-segment exposure in Asia/China.

Litigation
- asbestos & environmental (A&E) reserves; 'reviver' statutes reopening sexual-molestation claims (Century ~$1.5B reserves)medium
Chubb's A&E reserve estimation is sensitive to the legal environment; its run-off subsidiary Century carried ~$1.5 billion of gross reserves at year-end 2025, and changes such as 'reviver' statutes relating to sexual-molestation claims may give rise to additional claims previously barred by statutes of limitations.
“Changes in laws and regulations may have an adverse effect on Century's reserves; for example, the enactment of "reviver" statutes relating to claims of sexual molestation may give rise to additional claims that would have been barred by the statutes of limitations in effect at the time of the alleg[ed acts]”

Commodity & input dependence
- crop insurance (MPCI) tied to USDA federal program and commodity priceslow
Chubb's North America Agricultural Insurance MPCI program is offered in conjunction with the USDA in a federally regulated program where all approved providers offer the same forms/rates; 2025 net premiums written were affected by a federal government profit-share agreement adjustment ($179M) and lower commodity prices.
“Net premiums written for 2025 also reflected higher reported acreage from policyholders, and policy count growth, partially offset by lower commodity prices in the current year.”

Regulatory & policy
- terrorism-coverage reliance on TRIA/TRIPRA (extended through Dec 31, 2027)low
Chubb's terrorism-coverage availability depends on the U.S. Terrorism Risk Insurance Act (TRIA), extended under TRIPRA through December 31, 2027, which applies to certain of its operations; lapse or change in the federal terrorism backstop would alter Chubb's terrorism-risk exposure.
“The U.S. Terrorism Risk Insurance Act (TRIA), which was enacted in 2002 to ensure the availability of insurance coverage for certain types of terrorist acts in the U.S., has been extended under the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA) through December 31, 2027, and applies to certain of our operations.”
