A bill to amend the Clayton Act by modifying the notification requirements applicable to mergers and tender offers.

Amends the Clayton Act to eliminate the 15-day waiting period (and thus require a 30-day waiting period) following notification of a proposed acquisition in the case of a cash tender offer.

Requires the 30-day acquisition waiting period to be extended for an additional 30 days (or 60 days if, after the acquisition, the U.S. assets or probable annual U.S. sales of the acquiring person would exceed $1,000,000,000) if the Federal Trade Commission or the Attorney General requires submission of additional information or documentary material concerning the proposed acquisition.
