CY2021	us-gaap	Use Of Estimates UseOfEstimates	Use of EstimatesThe preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include revenue recognition, valuation of long-lived assets including identifiable intangibles and goodwill, accounting for income taxes including the related valuation allowance on the deferred tax asset and uncertain tax positions, contingencies and litigation, contingent acquisition consideration, and stock-based compensation. In the future, the Company may realize actual results that differ from the current reported estimates and if the estimates that the Company has used change in the future, such changes could have a material impact on the Company’s consolidated financial position, results of operations and cash flows.
