Marsh Risk, an insurance broker and business of Marsh, has launched MLOne, a first-of-its-kind US lead umbrella casualty facility aimed at delivering stronger protection and clearer claims coordination for clients.
The new business unit is part of Marsh’s expanding suite of excess casualty facilities, including its Bermuda-based BX1 and US-based MX1 facilities. These facilities aggregate and coordinate capacity from multiple insurers into a single block of follow-form coverage with a single claims decision maker.
MLOne has been designed to sit above any primary casualty program, consolidating up to $30 million of capacity into a single, quota-share lead umbrella block led by Allianz Commercial, who will assume claims handling for the entire quota share.
The new facility can be combined with BX1 and MX1 in a single program, further reducing contract inconsistencies and simplifying claims resolution, confirms Marsh.
Muffadal Lokhandwala, US Excess Casualty Practice Leader, Marsh Risk, commented, “MLOne represents an important step forward for clients seeking clear, dependable umbrella protection. Clients will gain greater coverage certainty and a more efficient placement and claims process—helping to reduce gaps and litigation risk, while improving program stability and balance sheet protection.”
Dan Aronson, US Casualty Leader, Marsh Risk, added, “MLOne builds on the momentum of our follow-form product family. Together with MX1 and BX1, we’re delivering a consistent, market-tested framework that simplifies excess casualty placement and enhances client outcomes. Our goal is to continue growing this suite of solutions, so clients have predictable, scalable options across their casualty portfolios.”
Mary Ann Stewart, Regional Head of Liability, North America, Allianz Commercial, said, “Allianz’s lead insurer role on this facility reflects our conviction that the casualty market needs smarter, more client-centered solutions. When insureds are navigating increasingly complex claims environments, having a single, accountable claims leader within the quota share structure makes a tangible difference — both in outcomes and in confidence. We are delighted to partner with Marsh Risk to deliver the certainty, efficiency, and advocacy that insureds require in today’s casualty market.”
