The settlement resolved allegations that the companies engaged in illegal and anticompetitive practices related to bids for highway pavement marking contracts on State of Oregon projects. The state alleged that 3M, a manufacturer of pavement striping tape, and SPM, a striping contractor, exchanged information regarding bids, coordinated bids, allocated projects and provided false certifications. As a result, the state alleged that competition was reduced and the government received less advantageous terms for the purchase and installation of roadway marking products. The companies denied wrongdoing. The settlement required 3M and SPM to pay a combined $750,000 to the State of Oregon. An additional $750,000 was made available as a credit to the Oregon Department of Transportation for a total of $1.5 million. The companies also agreed to refrain from conduct that could substantially lessen competition and to provide the Department ongoing certification of compliance.
