As originally reported in fiscal 2009, potentially dilutive common shares attributable to employee stock plans diluted shares were excluded from the diluted share calculation as they would have been anti-dilutive and would have reduced the net loss per share; however, as a result of reporting our AEG segment as discontinued operations, the anti-dilution of these potentially dilutive common shares is now based on income from continuing operations as compared to net income (loss) and are now included in the shares used in diluted per share calculation.
