We make significant estimates in many areas of our accounting, including but not limited to the following: long-term contracts, stock-based compensation, intangible assets and liabilities including goodwill, provision for excess and obsolete inventory, allowance for doubtful accounts, warranty obligations and income taxes. Actual results may differ from those estimates.</font></div><div style="line-height:120%;padding-left:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div></div>
