Plunging Profits

PPG Industries Inc., a Pittsburgh glass and resin maker, said Thursday that its annual profit plummeted 21% as it took a $44.2-million charge because of a pending sale of its biomedical division to Irvine-based Enhanced Imaging Technologies Inc. PPG announced last month that it was selling its biomedical systems division to Enhanced Imaging for $55 million. That deal is expected to be completed by the second quarter. PPG assembled its biomedical systems division in 1986 through acquisitions from Litton Industries and Honeywell Inc.
