Chubb

The company operates as a diversified insurance and reinsurance group. It underwrites personal, commercial, specialty and accident and health risks, including multinational commercial programmes, and assumes property and casualty reinsurance from primary carriers and captives. Value is created by assessing and pricing risk, providing tailored coverage and limits, and servicing claims and risk‑engineering needs for policyholders and cedants. Geographic diversification and a broad product set provide risk spreading across lines and territories.

Financially, the model is based on collecting gross written premiums up front, retaining an underwriting margin after claims and operating costs, and generating additional return on capital by investing the premium float and shareholder funds. The group also uses retrocession and ceding arrangements to manage its own risk and capital. Scale and underwriting expertise are central to maintaining underwriting discipline and supporting complex multinational and reinsurance structures.

Chubb is a global property and casualty insurance group headquartered in Switzerland and listed in New York through its parent, Chubb Limited. The company writes personal, commercial and specialty insurance and provides reinsurance capacity worldwide, including multinational programmes and accident and health products. It competes with other large P&C insurers such as Allianz, AIG, Zurich, AXA and Tokio Marine.

The group generates revenue primarily from gross written premiums on personal and commercial insurance policies and from reinsurance arrangements, supplemented by investment income on the float generated from premium reserves. Its customers include individuals and households, small and mid‑sized businesses, large corporates and other insurers and captives that purchase reinsurance capacity.
