15. Net Income (Loss) Per Common Share
Basic net income (loss) per share of common stock is computed using the weighted average number of common shares outstanding for the period. The calculation of potential common shares assumes the exercise of dilutive stock options and vesting of awards (RSUs and RSAs), net of assumed treasury share repurchases at average market prices. Nonqualified stock options totaling 1.3 million and stock awards totaling 0.3 million shares were excluded from the calculation of diluted net income per common share for the three months ended September 30, 2011, because they were anti-dilutive. In net loss periods, basic net loss per share and diluted net loss per share are identical since the effect of potential common shares is anti-dilutive and therefore excluded.
