Saint-Gobain SA’s record 896 million-euro ($1.2 billion) cartel fine may be reduced by European Union regulators within weeks as officials seek to correct a calculation error, according to a Jan. 30 Bloomberg report. Regulators will make small reductions in the penalty because they made a mistake in the way they evaluated auto glass sales, said two people familiar with the decision, according to Bloomberg. A 370 million-euro fine against Pilkington, a Nippon Sheet Glass Co. unit, may also be reduced for the same reason, one of the people said.
