Zurich, Switzerland – April 17, 2012 – The insurance segment of XL Group plc (“XL”) (NYSE: XL) today announced that it has restructured its International Primary Casualty business. In the new structure, four teams built around underwriting tasks and account type underscore a true client focus, allowing the unit to better respond to the needs of clients and brokers. International Primary Casualty serves large corporations in Europe, including the UK, Asia, Australia and Latin America.

Thomas Stamm, Chief Underwriting Officer International Primary Casualty, said: “We’ve seen that globalization and changing legislation pose increasing and similar risks to many of our clients. Some of these risks are particularly complex due to the nature of the client’s business or the projects they participate in. Our new structure lets us be even more nimble and innovative. By working closer together with our clients and brokers it’s now easier for us to find answers to their needs. To do this we bring together experts with a true entrepreneurial spirit and the best skill set to lead our new teams.”

The four teams are:

Underwriting Large Corporates, led by Reto Arrigoni, who moves to XL Group from Zurich. With over 20 years international experience in casualty underwriting and management roles, Reto will look after most of the International Primary Casualty existing clients and also seek profitable growth through new products and cross-selling.

Underwriting Complex Accounts, led by Joachim Walch, who has 25 years industry experience, fifteen of which have been with XL Group. Joachim is charged to develop new client and broker relationships, listening and working with them to create products that best fit their needs.

Underwriting Environmental Liability, led by Simon White, who 15 years ago was one of the first underwriters to provide exclusive environmental cover in the London market. Since then, he’s helped XL Group become one of the leading providers of environmental coverage worldwide. He’ll seek to grow and expand this business through new product development and geographical expansion.

Underwriting Management, led by Michael Rüsch, who has extensive casualty underwriting and underwriting services experience, is responsible for a multi-faceted group that contributes to the strategy, manages existing products and new product development, and runs the numbers that back up our business decisions.

Thomas Stamm added, “As we seek profitable growth through product innovation and geographic expansion, I am convinced and delighted that this new structure will let us get closer to clients and the market. To better respond to their needs.”
