On an ongoing basis, the Company evaluates its estimates, including those related to asset impairment, accruals for self-insurance and compensation and related benefits, contingencies and litigation, and income taxes. The Company bases these estimates on the information that is currently available and on various other assumptions that it believes are reasonable under the circumstances. Actual results could differ from those estimates under different assumptions or conditions.</font></div></div>
