Endurance Services Ltd is a specialty insurance group headquartered in Purchase, New York, with operations in the U.S., U.K., Bermuda, and other regions. Originally established as part of Endurance Specialty Holdings Ltd, the company specializes in property and casualty insurance and reinsurance, including crop insurance where it held a leading position in the U.S. Endurance built a well-balanced, diversified portfolio through profitable underwriting, risk management, and global expansion, culminating in its acquisition by Sompo Holdings. The company had a strong management team and focused on sustainable growth, serving businesses and institutions with specialized risk solutions. It was fully acquired by Sompo in 2017 and now operates as Sompo International. The firm employed several hundred professionals at its peak before the transition.

Investment Strategy

Endurance focused on underwriting specialty insurance and reinsurance lines with the highest risk-adjusted returns, leveraging expert teams to balance risk across products and regions. The company utilized disciplined underwriting, dynamic capital allocation, and reinsurance products to optimize financial stability and profitability. Investment management activities emphasized liquidity, risk-adjusted returns, and capital flexibility, with excess capital returned to shareholders unless new profitable opportunities were found. The firm proactively managed exposures to natural perils, crop insurance, and other specialty risks, maintaining robust enterprise risk management and a diversified, analytical approach toward portfolio growth.
