The Federal Trade Commission is amending Rules 4.10(d) and (e) of its Rules of Practice, which describe confidentiality protections for materials that the agency obtains pursuant to process in a law enforcement investigation, materials that the agency obtains voluntarily in lieu of such process that are designated confidential by their submitters, and other materials designated as confidential. These amendments conform the agency's rules to its disclosure authority under the International Antitrust Enforcement Assistance Act.
