Marsh Risk launches lead umbrella casualty facility with Allianz Commercial
Marsh Risk has launched MLOne, a US lead umbrella casualty facility providing up to $30 million of follow-form capacity under a single quota-share structure, expanding its casualty solutions portfolio alongside its Bermuda-based BX1 platform.
The new facility, MLOne, is designed to sit above any primary casualty programme and represents the latest addition to Marsh Risk’s excess casualty portfolio, alongside its Bermuda-based BX1 and US-based MX1 facilities. The facility aggregates capacity from multiple insurers into a single block of follow-form coverage with a single claims decision maker.
Allianz Commercial will lead the facility and assume claims handling responsibility for the entire quota share. MLOne can also be combined with BX1 and MX1 within a single programme, with the aim of reducing contract inconsistencies and simplifying claims resolution.
According to Marsh Risk, the facility is intended to provide greater coverage certainty while streamlining both placement and claims processes for clients.
Muffadal Lokhandwala (pictured), US excess casualty practice leader, Marsh Risk, said: “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 in North America at 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.”
