Bayer CropScience streamlines its management structures

Dr. Rüdiger Scheitza, Dr. Dirk Suwelack and Dr. Wolfgang Welter appointed to the Board of Management

- Bayer CropScience AG, one of the world's leading companies in the areas of crop protection, seeds and biotechnology, is adopting a new organizational structure effective July 1, 2004. "Following the successful integration of Aventis CropScience we can now streamline our structures and further enhance our focus on market requirements," explains Professor Friedrich Berschauer, the Chairman of the Board of Management of this Bayer subgroup. "We're going for a leaner organization, optimizing our strategic and operational decision-making, and redefining responsibilities."

Notably, there will now be a smaller Executive Committee, comprising the members of the Board of Management, the heads of the Regions and the heads of the Environmental Science and BioScience Business Groups. A number of changes are being made on the Board of Management.

CEO Berschauer and Dr. Bernward Garthoff, already responsible for research and development, will be joined on the Board of Management by Dr. Rüdiger Scheitza (Portfolio Management and Labor Director), Dr. Dirk Suwelack (Business Planning & Administration) and Dr. Wolfgang Welter (Industrial Operations and Investments).

Bayer CropScience's business activities in more than 120 countries will in future be organized into three regions (currently five): Americas, Europe & TAMECIS (Turkey, Africa, Middle East, Commonwealth of Independent States) and Asia Pacific.

Current board members Dr. Esmail Zirakparvar and Willy Scherf will take on new assignments in the United States: Dr. Zirakparvar will become Head of Bayer CropScience's new Americas Region, while Willy Scherf is relocating to Pittsburgh, Pennsylvania, to head up Bayer Corporate and Business Services.
