10. Income Taxes
 
The Company has not recognized any income tax provision (benefit) for the three and six months ended June 30, 2011, and June 30, 2010 due to continuing losses from operations.
 
The U.S. statutory federal income tax rate is reconciled to the Company’s effective income tax rate as follows:

The Company assesses the recoverability of deferred tax assets and the need for a valuation allowance on an ongoing basis. In making this assessment, management considers all available positive and negative evidence to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized in future periods. This assessment requires significant judgment and estimates involving current and deferred income taxes, tax attributes relating to the interpretation of various tax laws, historical bases of tax attributes associated with certain assets and limitations surrounding the realization of deferred tax assets.
 
As of June 30, 2011, the net operating loss carryforward was $196 million, which will begin to expire if not used by December 31, 2028. The U.S. federal statute of limitations remains open for our 2006 and subsequent tax years.
