Significant items subject to such estimates and assumptions include revenue recognition, internal-use software development costs, income taxes, stock-based compensation, allowance for doubtful accounts, valuation of acquired intangible assets of Dosh and Bridg, valuation of contingent consideration for Bridg, income tax valuation allowance and contingencies. We base our estimates on historical experience and on assumptions that we believe are reasonable. Changes in facts or circumstances may cause us to change our assumptions and estimates in future periods and it is possible that actual results could differ from our current or revised future estimates.</span></div>
