The most important of these estimates and assumptions relate to the following: allowance for doubtful accounts, fallouts and other trade accounts receivable reserves; income taxes; self-insured liabilities for workers’ compensation and health insurance; obligations for defined benefit pension plans and goodwill and identifiable intangible assets and any related impairment. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates.</font></div></div>
