Such estimates include the value and allocation of purchase consideration, valuation of accounts receivable, Reimbursable receivables, Warehouse receivables, Investments, Goodwill, intangible assets, derivative financial instruments, other long-lived assets, earn-out liabilities, legal contingencies, assumptions used in the calculation of income taxes, incentive compensation, self-insurance program liabilities, and retirement and other post-employment benefits, among others.</span></div><div style="margin-bottom:6pt;margin-top:6pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:130%">These estimates and assumptions are based on management's best estimate and judgment. We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Market factors, such as illiquid credit markets, volatile equity markets and foreign currency exchange rate fluctuations can increase the uncertainty in such estimates and assumptions. Because future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Although actual amounts may differ from such estimated amounts, we believe such differences are not likely to be material.</span></div>
