For more than 30 years, our lawyers have been instrumental in the structuring, formation and operation of onshore and offshore captives and insurers.

We are well-known for our experience in the formation of Bermuda-based insurance companies, including Everest Re Group, LaSalle Re, Intrepid Re and Endurance Specialty. We have been counsel or co-counsel in high-profile IPOs, including those of ACE, Assured Guaranty, LaSalle Re, IPC Re, Montpelier Re and Endurance. We have also structured and formed US and offshore captives for many of our non-insurance clients. Several of our captive clients are organized as risk retention groups under the Federal Risk Retention Act of 1986.
