On an ongoing basis, management evaluates its estimates based upon historical experience, observance of trends, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;"></font></div></div>
