On an ongoing basis, the Company evaluates its estimates, including those related to inventory valuation, allowances for doubtful accounts, warranty, sales return reserves and the recoverability of long-lived assets. Management of the Company bases its estimates on historical experience and on various other assumptions. Actual results could differ from those estimates.</span></div>
