Significant areas requiring the use of estimates and measurement of uncertainty include determination of valuation for deferred tax assets, uncertain income tax positions, assessment of impairment of long-lived assets and goodwill, assessment of environmental matters, allocation of purchase price and fair value estimates for business combinations, equity-based compensation and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions.</font></div></div>
