AKRON (May 7)—The trans-Atlantic price collusion investigation of five global EPDM producers has spawned a growing list of civil lawsuits in the U.S. seeking damages from some or all of them. Among the companies known to have filed suit seeking unspecified damages are Freudenberg NOK G.P., Duraplas Corp., Reeves Brothers Inc. and the former owner of Functional Products Inc. The suits likely will evolve into a class action suit, those involved said. The EPDM producers being sued are Crompton Corp./Uniroyal Chemical Co., DuPont Dow Elastomers L.L.C., Bayer A.G. and DSM N.V. To date ExxonMobil Chemical Co. has not been named in the suits monitored. The suits indicate plaintiffs are eligible for treble damages under U.S. antitrust laws. The price collusion investigation, involving officials from U.S., Canadian and European Union competition authorities, was triggered by Crompton, which said in December it contacted the authorities after it "became aware of such behavior by manufacturers of EPDM." DuPont Dow declined to comment on the civil suits.
