Our more significant estimates include the excess, obsolete and slow moving inventory reserves, warranty reserves, customer rebates, determination of the deferred and accrued revenue components of multiple performance obligations sales agreements, estimated costs to complete obligations associated with deferred and accrued revenue, estimated income tax provision and income tax contingencies, the fair value of stock-based compensation, impairment of goodwill, valuation and estimated lives of intangible assets, estimated pension liability, fair value of investments and the evaluation of other-than-temporary declines in the value of investments. Actual amounts could differ significantly from these estimates.</p> <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">During the three months ended June 30, 2019, the Company revised the methodology in how it estimates its excess and obsolete inventory reserves. Under the revised methodology, <span style="color:#000000;">we establish reserves for estimated excess and obsolete inventory equal to the difference between the cost of the inventory and the estimated net realizable value of the inventory based on historical usage, known trends, inventory age, and market conditions. When we dispose of excess and obsolete inventories, the related disposals are charged against the inventory reserve. See Note 8 of Notes to Condensed Consolidated Financial Statements for additional information.</span></p>
