Estimates are used for, but not limited to, supplier revenue, allowance for credit losses, depreciable lives of property and equipment, acquisition purchase price allocations including valuation of acquired intangible assets and goodwill and contingent consideration, valuation of operating lease right-of-use (“ROU”) assets, impairment of goodwill, other intangible assets, long-lived assets, capitalized client incentives and investments in equity method investments, valuation allowances on deferred income taxes, valuation of pensions, interest rate swaps, earnout shares and contingent liabilities. Actual results could differ materially from those estimates.</span></div>
