John Reece

A chartered accountant, John Reece joined chemicals conglomerate Ineos in 2000, less than two years after the company's founding. Formerly a partner at PricewaterhouseCoopers, where he specialized in working with chemicals firms, Reece is now Ineos' chief financial officer. The $40 billion (sales) company produces everything from specialty chemicals to plastics and insulation. It has also become a major player in the U.K. shale industry, with production fields in the North Sea and exploration areas in England and Scotland. Reece graduated from Cambridge with a degree in economics; he derives his fortune from his minority stake in Ineos.
