Fujitsu said Wednesday that all material reviews by governmental agencies of the United States, Japan, Canada and Europe have been completed and the necessary approvals obtained in connection with its proposed acquisition of all the outstanding shares of Amdahl Corp not currently owned by Fujitsu. The company also said that, as of the close of trading on the American Stock Exchange on Tuesday, more than 18.7 million shares of Amdahl stock have been tendered. Together with the shares already owned by Fujitsu, the tendered shares give Fujitsu roughly 57% ownership of Amdahl, exceeding the minimum number that Fujitsu must receive as a condition of closing the tender offer.
