Sard Verbinnen & Co continues to advise and represent longtime client SAC Capital as the hedge fund this week was hit by criminal charges and has faced probes for years.

sacSard managing director Jonathan Gasthalter, a former press hand for the New York State attorney general, has led the SAC account for several years.

The FBI on Wednesday announced insider-trading charges against four SAC companies and portfolio manager Richard Lee, who pled guilty on July 23 to conspiracy and fraud charges.

"SAC has never encouraged, promoted or tolerated insider trading and takes its compliance and management obligations seriously," said a statement released by Gasthalter. "The handful of men who admit they broke the law does not reflect the honesty, integrity and character of the thousands of men and women who have worked at SAC over the past 21 years. SAC will continue to operate as we work through these matters."

Earlier insider trading cases against seven SAC executives going back three four years have resulted in five guilty pleas, the FBI said.

SAC chief Steven Cohen has not been charged.
