Significant estimates and assumptions by management affect the Company’s revenue recognition for multiple performance obligation arrangements, valuations, purchase price allocations and contingent consideration related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of intangible assets and goodwill, amortization methods and periods, accounts receivable reserves, inventory excess and obsolescence reserves, warranty reserves, certain accrued expenses, restructuring and other related charges, contingent liabilities, tax reserves, deferred tax rates and recoverability of the Company’s net deferred tax assets and related valuation allowances, and stock-based compensation.</span></div><div style="margin-top:9pt;text-align:justify;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Although the Company regularly assesses these estimates, actual results could differ materially from these estimates.
