The termination of Bayer\'s listing on the New York Stock Exchange (NYSE) became effective September 26, 2007. Since September 27, 2007, Bayer ADSs are traded in the U.S. over-the-counter market. Effective on December 28, 2007, the certification of Bayer AG of its termination of registration of its ordinary shares under the U.S. Securities Exchange Act of 1934, as amended (the \"Exchange Act\") became effective pursuant to Rule 12h-6 under that Act. With that event, Bayer’s obligations under the Exchange Act to file financial reports and other documents with the U.S. Securities and Exchange Commission (the \"SEC\") have permanently terminated, and Bayer is no longer subject to the various provisions and requirements of the Sarbanes-Oxley Act of 2002. Bayer will continue to publish material documents on this website in English as required by Rule 12g3-2(b) under the U.S. Securities Exchange Act.
