Reclassifications: Certain reclassifications of prior year balances have been made to conform to the current year presentation. These reclassifications had no effect on the reported financial position or results of operations. The most significant reclassifications were to reclassify the Cerro Bayo statements of operations from historical presentation to income (loss) from discontinued operations in the consolidated statements of operations for all periods presented. Correction of an Immaterial Error: In the fourth quarter of 2010, the Company identified an error in the amount of income tax benefit recognized in 2009 and the three month period ended March 31, 2010.
