UBS has announced that Sergio Marchionne, senior independent director of the Board of Directors, and Peter Voser have decided not to stand for re-election to the Board of UBS AG at the annual general meeting (AGM) which will take place on 14 April 2010.

He was elected to the BoD at the AGM 2007 and appointed independent vice chairman and senior independent director in 2008.

Peter Voser, CEO and executive BoD member of Royal Dutch Shell plc in London, was elected to the BoD at the AGM 2005. He is a member of the governance and nominating committee and of the strategy committee.

Kaspar Villiger, Chairman of the Board of UBS, said of these decisions: "I would like to thank the outgoing board members Sergio Marchionne and Peter Voser for their strong contributions to the management of our firm. With their comprehensive economic and entrepreneurial competence they supported UBS in difficult times and provided significant input to the stabilization and the successful initiation of the turnaround of our company."

UBS will provide information at a later stage regarding candidates to succeed the outgoing board members.
