W.W. Grainger (GWW)

Chairman and Chief Executive Officer Richard L. Keyser said, “Jim’s addition to the board is part of the company’s succession plans. We are delighted to have him participate in the decisions we need to make as we aggressively grow the business.”

David W. Grainger has decided not to stand for reelection at the company's annual meeting.

Keyser said, “David has been a mainstay of the company and board of directors, and for the past 54 years he has helped transform Grainger into the leading industrial distributor of facilities maintenance products in North America. While he is stepping down from the board, as senior chairman he will continue to provide us his counsel.” John W. McCarter, Jr., Chairman of the Board Affairs and Nominating Committee, said, "It is difficult to lose a strong board member. We are glad that David is staying on with the company in a senior advisory role."
