The Company believes that its most significant estimates are those related to revenue recognition, valuation and impairment of investments, its assessment of ownership interests as variable interest entities and the related determination of consolidation, share-based compensation expense, fair value of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowances for doubtful accounts. On an ongoing basis, management evaluates its estimates based on historical experience and on various other factors that the Company believes to be reasonable under the circumstances. Actual results could materially differ from those estimates.</span></div>Additionally, the full impact of the COVID-19 pandemic is unknown and cannot be reasonably estimated. However, the Company has made appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent there are differences between these estimates and the actual results, our Condensed Consolidated Financial Statements could be materially affected.
