He is the co-author of Bloomberg BNA Corporate Practice Portfolio Series No. 15-4th, Inside Information: Prevention of Abuse.  This portfolio volume addresses the obligations of a U.S. public company and its insiders arising from the possession of material nonpublic information concerning the company or its securities. After initially discussing what information is deemed to be material and nonpublic, the portfolio then analyzes the prohibitions against insider trading, the scope of the company's obligation to disclose material information, and the formulation of corporate procedures that promote compliance with the insider trading prohibitions and disclosure requirements. The portfolio also discusses potential liabilities and statutory defenses for insider trading, as well as the liability for short-swing profits under Section 16 of the Securities Exchange Act of 1934.
