Alcan ( AL) chief Dick Evans eliminated the office of the president and the position of operating chief as he took over the Montreal-based aluminum company.Evans made the move as he formally took the reins as president and CEO from his predecessor, Travis Engen. Alcan said in October that Engen would retire this month and that Evans would take over. Engen led Alcan for five years starting March 12, 2001. On Monday, the company said the presidents of its four business groups will report to Evans and sit on the executive committee. The presidents are Jacynthe Cote, bauxite and alumina; Cynthia Carroll, primary metal group; Michel Jacques, engineered products; and Christel Bories, packaging. "It is a pleasure and honor to lead this team of talented and seasoned officers who have played key roles in the company's transformation in recent years," Evans said. "Our commitment to Alcan's values, principles and financial targets is unwavering. With the Pechiney integration completed, however, we will increasingly shift our focus to executing and delivering on our targets." Alcan also said the corporate head office located in Montreal will continue to focus on strategy development, governance, policy and compliance. Michael Hanley remains chief financial officer.
