The Federal Trade Commission is amending its regulations, which govern applications for approval of proposed divestitures, acquisitions, or similar transactions that are subject to Commission review under outstanding orders, and is also making a conforming amendment. The principal changes accomplished by these amendments are to clarify the nature of the materials that will be placed on the public record in prior approval proceedings, to clarify the timing of such placement, and to provide expressly that, in appropriate cases, the Commission may shorten, eliminate, extend or reopen a comment period.
