Item 7.01 Regulation FD Disclosure.

There were a number of questions raised during the July 28, 2005 analyst teleconference with respect to carbon black feedstock costs and the manner in which prices are adjusted under our carbon black supply contracts for such costs. In the discussion, we commented on the method by which the changes in feedstock costs impact our contract prices and management believes it is useful to provide further detail regarding these adjustments. Generally, our carbon black supply contracts provide for a price adjustment on the first day of each quarter to account for changes in feedstock costs and, in some cases, changes in other relevant costs. The feedstock adjustments are based upon the average of a relevant index over a three month period. Because of the need to communicate these adjustments to our customers in a timely manner, the contracts typically provide for the adjustments to be calculated in the month preceding the quarter. Accordingly, the calculation is typically based upon the average of the three months preceding the month in which the calculation is made. For example, the price adjustment applicable to the quarter commencing July 1 is calculated in June using the index average during the months of March, April and May.

With respect to the relevant feedstock index, the formulas use indices that approximate movements in our actual feedstock costs. The indices typically used are Platt's Gulf Coast Spot Assessment 3% Sulfur, Platt's Rotterdam 1% Sulfur and Platt's New York #6 1% Fuel Oil.
