Operating Loss Carryforwards, Limitations on Use	A formal Section 382 study would be required to determine the actual allowable usage of U.S. net operating loss carryforwards.  However, it is possible that past ownership changes will result in the inability to utilize a significant portion of the Company’s NOL carryforward that was generated prior to any change of control.  The Company’s ability to use its remaining NOL carryforwards may be further limited if the Company experiences an IRC Section 382 ownership change in connection with future changes in the Company’s stock ownership.  Based on information currently available, the Company currently estimates that $206.5 million of the U.S. net operating losses will not be able to be utilized and have reduced the Company’s deferred tax asset accordingly.
