NEW YORK-The price of Ply Gem Industries Inc. stock fell 11.2 percent April 11, the day after Monte R. Haymon abruptly resigned as president and chief operating officer. Most of Ply Gem's business comes from wood products, but the New York building products maker has three plastics companies: Variform Inc., a vinyl siding extruder in Kearney, Mo.; Great Lakes Window Inc., a vinyl window fabricator in Toledo, Ohio; and Richwood Building Products Inc. of Richwood, Ky., which injection molds siding accessories.
Haymon, former president and chief executive officer of Packaging Corp. of America, joined Ply Gem in January 1994. Ply Gem announced his resignation on April 10. No reason was given. Haymon will continue as a consultant to Ply Gem.
Ply Gem's stock fell $2, to $15.875 April 11 on the New York Stock Exchange. The company has started a search for a new president.
