Earnings (Loss) Per Share [Abstract]


NOTE H —	EARNINGS (LOSS) PER SHARE

The following table sets forth the numerators and denominators used in the computation of basic and diluted earnings (loss) per share. Options to purchase 9.9 million and 10.2 million shares of common stock were excluded from the computation of diluted earnings per share for fiscal 2011 and 2010, respectively, because the exercise price was greater than the average market price of the common shares and, therefore, their effect would have been antidilutive. All outstanding stock options were excluded from the computation of diluted earnings per share for fiscal 2009 because they were antidilutive due to the net loss recorded during that year. Additionally, the convertible senior notes were excluded from the computation of diluted earnings per share for all three years because they were antidilutive.
