  On June 12, 2007, Cabot Corporation ("Cabot") agreed to settle the federal class action lawsuits pending against it alleging that Cabot and other carbon black manufacturers had violated antitrust laws in setting prices for carbon black sold in the United States.  Cabot&#x2019;s share of the settlement cost is $10 million.  Cabot denies any wrongdoing of any kind in these cases, and strongly believes that it has good defenses to these claims.
