LONDON (Oct. 10)—Bayer A.G. and Flexsys N.V./S.A. confirmed that they, like Crompton Corp., are cooperating with an investigation of price collusion concerning rubber chemicals. The probe is part of a larger investigation into cartels in the chemicals sector by U.S. and European authorities. Crompton issued a statement on Oct. 8 saying authorities from the U.S. and European Union had issued subpoenas to the company and several individual employees in connection with, "collusive dealings" in the rubber chemicals industry. Bayer said antitrust authorities visited its U.S. offices and headquarters in Leverkusen, Germany, at the end of September. A spokesman said the investigation appears to go back as far as 1994, and only the rubber chemicals business, rather than the rubber and chemical business as a whole, is under study. Walter Kymmell, general counsel for Flexsys, confirmed that the company is cooperating with the authorities in this matter, but declined to make any further comment.
