A New York-based investor group called F.A.C. Inc. has offered to buy Victor Posner’s Fischbach Corp., the nation’s largest electrical contractor, for $25 per share, or $97.5 million. A Fischbach spokesman had no comment on the bid. Fischbach gained attention after Ivan F. Boesky pleaded guilty to a criminal charge that he filed a false document with the SEC relating to his trading in Fischbach stock. Most recently, Posner, Fischbach’s chairman, was charged in a civil case brought by the SEC for allegedly participating in a massive securities fraud with investment banker Drexel Burnham Lambert Inc. and the head of its “junk bond” department, Michael Milken.
