Estimates are based upon historical factors, current circumstances, and the experience and judgment of management. Management evaluates its assumptions and estimates on an ongoing basis and may engage outside subject matter experts to assist in its valuations. Significant items subject to such estimates and assumptions include valuation of business combinations including acquired intangible assets and goodwill, loss contingencies, the recognition and measurement of current and deferred income taxes, including the measurement of uncertain tax positions, and valuation of assets and liabilities and results of operations of our discontinued operations. Actual results could differ from such estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the COVID-19 pandemic.</span></div>
