Chubb and Zurich North America, in collaboration with National Indemnity Company, have established a new excess casualty insurance facility targeted at large national and multinational corporations.
This facility will deliver up to $100m in lead excess casualty insurance capacity on a claims-made basis.
It will begin underwriting business with immediate effect, with coverage effective from 1 July 2025 in the US.
The coverage is underwritten by Chubb and Zurich and backed by National Indemnity Company, part of Berkshire Hathaway.
It features a unified access point through either Chubb or Zurich, offering “consistency” in coverage terms, and “expert ” claims management, the insurers said in a statement.
Chubb president and chief operating officer John Keogh stated: “This initiative, between three of the largest, most experienced insurers in the large account market, is our effort to bring a new approach in terms of insurance protection and claims capability, that best serves those clients who are more and more often the target of legal abuse.”
