We consider our most critical accounting estimates to be future metals prices; obligations for environmental, reclamation and closure matters; mineral reserves; and valuation of business combinations. Other significant areas requiring the use of management assumptions and estimates relate to reserves for contingencies and litigation; asset impairments, including long-lived assets and investments; valuation of deferred tax assets; and post-employment, post-retirement and other employee benefit assets and liabilities. We have based our estimates on historical experience and on various other assumptions that we believe to be reasonable. Accordingly, actual results <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may </div>differ materially from these estimates under different assumptions or conditions.</div></div></div></div>
