accruals for mine reclamation and closure costs (including perpetual water treatment) totaling
$205,632 and $98,940, respectively. The portion of the costs expected to be incurred within a year
was $14,908 and $8,375, as of December 31, 2009 and 2008, respectively, is included in <i>Accrued
expenses and other current liabilities</i>. There were no assets that were legally restricted for
purposes of settling asset retirement obligations at December 31, 2009 or 2008. These regulatory
obligations are secured by surety bonds.
