While his contributions to Bain Capital’s success are too numerous to list in their entirety, there are some key accomplishments that were central to our firm’s growth. At a time when few private equity firms moved into new asset classes, Paul played an important role as a senior advisor in the founding and early development of Brookside Capital. He was one of the partners who recognized a new strategic opportunity for expansion into Asia, helping to create the investment strategy and build the team. His guidance was critical to the establishment of our portfolio group, which has become one of our key levers in growing great companies. And, he led the industrials vertical which has made investments in more than 50 companies since its inception. A Bain Capital spokesman declined comment.
