The successful completion of our planned acquisition of Komag is subject to risks and uncertainties and in the event we fail to complete the acquisition our stock price could suffer and our relationship with vendors and customers may be adversely impacted.
Our ability to complete the planned acquisition of Komag is subject to risks and uncertainties, including, but not limited to, the risk that a condition to closing of the transaction may not be satisfied and the risk that we fail to obtain the financing necessary to complete the transaction. There is also no assurance that an adequate number of Komag shares will be validly tendered, and not withdrawn, in the tender offer sufficient to satisfy our minimum tender offer condition. In the event that the tender offer or merger is not completed or is delayed, the current market price of our common stock may decline if based on an assumption that the merger will occur as contemplated during the third calendar quarter of 2007. Additionally, these uncertainties regarding the merger may adversely affect our relationships with our vendors and customers.
