The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production depreciation calculations; future metal prices; environmental remediation, reclamation and closure obligations; estimates of recoverable gold and other minerals in stockpiles; estimates of fair value asset impairments; write-downs of inventory, stockpiles to net realizable value; valuation allowances for deferred tax assets; provisional amounts related to income tax effects of newly enacted tax laws; and stock-based compensation. Management routinely makes judgments and estimates about the effects of matters that are inherently uncertain and bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances. Actual results could differ from these estimates. </span></p>
