subtotals), includes an adjustment for corporate expenses. As these costs most likely represent normal operating costs of your business, they would not be an appropriate <FONT STYLE="white-space:nowrap">non-GAAP</FONT> adjustment. Please revise
future filings accordingly. See guidance in Question 100.01 of the CD&amp;I on <FONT STYLE="white-space:nowrap">non-GAAP</FONT> Financial Measures. </P>
