Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill, intangible assets acquired from business acquisitions, warranty liabilities, accruals for customer programs and related breakage when appropriate, sales return reserves, allowance for doubtful accounts, inventory valuation, contingent consideration from business acquisitions and periodical reassessment of its fair value, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.</font></div></div>
