Sompo International was established in March 2017 with the acquisition by Sompo Holdings, Inc. (Sompo) of Endurance Specialty Holdings, Ltd. and its wholly owned operating subsidiaries. Sompo’s core business encompasses one of the largest property and casualty insurance groups in the Japanese domestic market. Seeking opportunities to grow their business globally, Sompo acquired Endurance, a global provider of property and casualty insurance and reinsurance, to effectively become their international operation.
Endurance was founded in 2001 with approximately $1.2 billion in capital. Based in Bermuda, the initial operation focused on property catastrophe reinsurance and excess coverage for large commercial insurance accounts.
