Bayer proposes increasing dividend to EUR 0.95
Thomas de Win elected Vice Chairman of the Supervisory Board
Leverkusen / March 2, 2006 — Bayer AG’s Supervisory Board today accepted the proposal of the Board of Management to recommend to the Annual Stockholders’ Meeting on April 28, 2006, a dividend for fiscal 2005 of EUR 0.95 per share. With some 730 million shares, this would represent a payout of EUR 694 million, an increase of 73 percent. For fiscal 2004, a dividend of EUR 0.55 per share was paid.
“Fiscal 2005 was a very good year for Bayer and we would like our stockholders to participate appropriately in our success,” says Werner Wenning, Chairman of the Board of Management. The Bayer Group’s financial statements will be presented and discussed at the Spring Financial News Conference on March 6, 2006.
The Supervisory Board also elected Thomas de Win as its Vice Chairman. He takes over from Erhard Gipperich, who retired at the end of January 2006. “We would like to thank Mr. Gipperich for his contribution and wish Mr. de Win all the best in his new post,” said Supervisory Board Chairman Dr. Manfred Schneider.
Before the Supervisory Board meeting de Win (47) had been appointed Chairman of the Bayer Central Works Council. He has been a member of the Supervisory Board since April 2002.
