Polaroid Corp., citing costs of a corporate restructuring and the expenses of thwarting a hostile takeover bid by Shamrock Holdings of Burbank, posted a $50.4-million loss for its third quarter. The loss, on revenue of $436.3 million, contrasted with a profit of $24.4 million on revenue of $425.9 million in the 1987 period. The 1988 quarter’s figures include a $97-million charge to cover costs of restructuring, global distribution of 35-millimeter color film and a $300-million employee stock ownership plan. The Cambridge, Mass., firm also attributed the loss to start-up costs for its Impulse camera line.
