Louisiana-Pacific Corporation (NYSE: LPX) announced today that Archie W. Dunham retired from the board of directors at the Annual Meeting of Shareholders as required by the mandatory retirement age in the bylaws. Mr. Dunham has served on the board since 1996 and during his tenure served as the Chairman of the Finance and Audit Committee and was also a member of both the Compensation Committee and Executive Committee. “Archie has made many contributions to LP during his board service, both in up and down markets,” said Curt Stevens, chief executive officer. “His vast business experience, strong ethical principles and his financial savvy have served LP shareholders very well.” “From my perspective, Archie is the consummate director,” continued Gary Cook, Chairman of the Board. “He brought his international business experience, knowledge of commodity markets and insights into the political and regulatory process to bear in all of our deliberations. We wish Archie well and know that we will miss his participation going forward.” In preparation for Mr. Dunham’s retirement, the board of directors reviewed its current size and determined to reduce the number of board members from nine to eight, so there will be no search for a new member.
