“A respected CEO and industry leader, Bill’s background, commercial insight and experience expanding business and market access will bring new perspectives to an already strong and diverse Board of Directors,” said Mark Rohr, Celanese chairman and chief executive officer. “We look forward to his ability to help us identify intriguing new growth opportunities.
