The Commission has levied fines totaling €487 million on Asahi, Guardian, Pilkington and Saint- Gobain for having coordinated price increases and other commercial conditions for flat glass in the European Economic Area (EEA) between 2004 and 2005. The cartel concerned flat glass used in the construction sector for windows, doors and mirrors including basic float glass, low emissivity glass (glass coated to reduce heat transfer), laminated glass and unprocessed mirror glass. The cartel participants, which collectively held approximately 80 percent of the flat glass market in the EEA, were alleged to have conducted meetings to discuss and agree on the level and timing of price increases, target prices as well as minimum prices, and to have exchanged sensitive business information. The investigation was initiated by the Commission on the basis of information gathered by several Member States’ Competition Authorities.
