The Lubrizol Corporation has made several officer changes. These changes were driven in part by the completed acquisition of Lubrizol by Berkshire Hathaway, as well as by the retirement of some executives. James L. Hambrick remains Lubrizol's chairman, president and chief executive officer. In addition to Hambrick, Lubrizol's executive leadership team includes the following individuals: Suzanne Day, corporate vice president, general counsel and chief ethics officer; Bob Graf, corporate vice president, research and development, as well as assuming product safety and compliance responsibilities; John King, corporate vice president, information systems and business processes; Eric Schnur, president, Lubrizol Advanced Materials; Dan Sheets, president, Lubrizol Additives; Greg Taylor, corporate vice president, strategy, development and communications; Brian Valentine, corporate vice president, chief financial officer and treasurer, as well as assuming global risk management responsibilities and Mike Vaughn, who will become corporate vice president, operations, supply chain and HSES (effective upon the retirement of Larry Norwood in 2012).
In addition, Andy Panega, joined Lubrizol as corporate vice president, human resources. Panega brings 30 years of experience in human resource management, serving in both corporate and consulting roles. He held leadership roles in human resources at General Mills, Tonka Corporation, Dun & Bradstreet and R.R. Donnelley and Sons.
