Income Taxes

We are not presently a taxpayer and have not recorded a net liability for international, federal or state income taxes in any of the periods included in the accompanying financial statements. Our Consolidated Statements of Operations for the three and nine months endedSeptember 30, 2011 and 2010 include no income tax benefits.

During the third quarter of 2010, largely due to the increased level of trading activity in our shares, we experienced an ownership change within the provisions of Internal Revenue Code ("IRC") Section 382 that will subject approximately $855 million of our existing net operating loss ("NOL") carryforwards to the annual NOL utilization limitations.  The applicable Section 382 limitation may have affected our ability to fully utilize our existing tax NOL carryforwards.  Our ability to fully utilize our existing tax NOL carryforwards is dependent on increasing the recognition of built-in gains in the five-year period following the above-referenced ownership change. We will continue to monitor trading activity in our shares which may cause an additional ownership change which may ultimately affect our ability to fully utilize our existing tax NOL carryforwards.
