Management makes its best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: revenue reserves; self-insurance accruals; long-term incentive compensation; tax liabilities; loss contingencies; litigation claims; and impairment assessments on long-lived assets and goodwill.</span></p>
