Actual results may differ significantly from those estimates. The estimates underlying the Company's Consolidated Financial Statements relate to, among other things, the valuation of goodwill, other long-lived tangible and intangible assets, the valuation of investments in private companies, income taxes, contingencies, stock-based compensation, the allowance for expected credit losses (also referred to as allowance for doubtful accounts), customer chargeback provisions and the accrual of obligations for loyalty and other incentive programs.</span></div>
