Marsh Risk today announced the launch of BX1, a new insurance facility based in Bermuda and designed to address challenges of growing exposures and complexity in the US casualty insurance market.

BX1 offers a unified block of $50 million excess casualty capacity, “placement certainty, and superior policy terms tailored to meet the complex needs of the challenging US casualty market”, Marsh, the global insurance broker and risk adviser, said in a statement.

BX1, a solution designed for US-based clients, consolidates capacity from leading Bermuda insurers Ascot, Markel, Ark, and Sompo under a single Marsh Bermuda contract.

This structure helps simplify documentation and claims handling by providing a single claims decision-maker and contact, reducing administrative complexity and claims expenses for clients.

The policy is issued on the proprietary Marsh XSellence excess casualty form, delivering follow-form coverage, and includes affirmative coverage for punitive damages — a critical insurance protection often excluded or limited in traditional casualty programmes, Marsh said.

With a minimum attachment point starting as low as $10 million and flexibility to attach at higher levels, “BX1 is designed to meet the needs of complex casualty placements across most industries”, the statement added.

Lindsay Roos, Bermuda chief executive officer, Marsh Risk International Placement, said: “The US casualty market continues to present significant challenges, with increasing complexity and exposure for clients.

“BX1 addresses these challenges by offering a large, consolidated block of capacity with placement certainty and streamlined claims handling. This facility provides our clients with clarity, enhanced coverage, and the confidence to navigate a demanding liability environment with greater ease.”
