The Company’s management regularly assesses these estimates, which primarily affect revenue recognition, allowance for credit loss, the valuation of goodwill and intangible assets, leases, stock-based compensation and income tax provision. Actual results could differ from those estimates and such differences may be material to the accompanying unaudited condensed consolidated financial statements.</span></div>
