The Hart-Scott-Rodino Act requires under certain circumstances that prospective acquirers of voting securities or assets apply for clearance from regulators. Requests for early termination or clearance are granted when the Federal Trade Commission and the antitrust division of the Department of Justice have determined that they won't take action during the waiting period. The following is a list of companies or people to which the FTC has granted early clearance of antitrust concerns under the HSR Act: NAME OF ACQUIRING PERSON NAME OF ACQUIRED PERSON DATE NAME OF ACQUIRED ENTITY TERMINATED _____________________________________________________________ AT&T Inc.
