Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. These estimates and assumptions include valuing equity securities in share-based payment arrangements, estimating the fair value of equity instruments recorded as derivative liabilities, useful lives of depreciable assets and whether impairment charges may apply, and the fair value of environmental remediation liabilities.</font></div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>
