B. Explanations
As of 1 July 2008, the Board of Directors amended the governance structure of UBS AG and the new organization regulations of the company became effective as of the same date. The new model clarifies the separation of responsibilities between the Board and the Group Executive Board and abolishes the Chairman's Office. As a result, the Articles of Association will have to be amended accordingly.
