## Abstract

The Federal Trade Commission ("Commission" or "FTC") is amending the Hart-Scott-Rodino ("HSR") Premerger Notification Rules ("Rules") that require the parties to certain mergers and acquisitions to file reports with the FTC and the Assistant Attorney General in charge of the Antitrust Division of the Department of Justice ("the Assistant Attorney General" or "DOJ") (together the "Antitrust Agencies" or "Agencies") and to wait a specified period of time before consummating such transactions. The Commission is amending the Antitrust Improvements Act Notification and Report Form ("HSR Form") and Instructions to require use of 10-digit codes based upon the North American Product Classification System in place of the 10- digit codes based upon the North American Industry Classification System.
