March 19: Boyd L. Jefferies, founder of the Los Angeles securities firm Jefferies & Co., agrees to plead guilty to two criminal charges involving securities law violations, including one deal involving Boesky. He is not accused of insider trading. Jefferies, who was implicated by Boesky, resigns as chairman of Jefferies & Co. and agrees to stay out of the securities business for at least five years.

(Sandy) Lewis, a well-known takeover speculator, on charges that he manipulated the stock price of Fireman’s Fund Corp. in 1986 to help American Express Co. sell part of its Fireman’s Fund stake for more money. The indictment is based partly on disclosures by Boyd Jefferies more than a year earlier.


Dec. 22: Corporate raider and Singer Co. Chairman Paul A. Bilzerian is indicted by a grand jury on 12 felony counts linked to four unsuccessful takeover deals in 1985 and 1986.
