[1] The amount of the dividend on the convertible preferred stock per common share obtainable on conversion of the convertible preferred stock was less than basic earnings per share for Series 1, 3 and 4 preferred stocks for Fiscal 2013 and 2012. Therefore, conversion of these convertible preferred stocks were included in diluted earnings per share for Fiscal 2013 and 2012. The amount of the dividend on Series 3 convertible preferred stock per common share obtainable on conversion of the convertible preferred stock was less than basic earnings for Fiscal 2011. Therefore, conversion of Series 3 preferred shares were included in diluted earnings per share for Fiscal 2011. The amount of the dividend on Series 1 and Series 4 convertible preferred stock per common share obtainable on conversion of the preferred stock was higher than basic earnings for Fiscal 2011. Therefore, conversion of Series 1 and Series 4 preferred shares were not reflected in diluted earnings per share for Fiscal 2011 because it would have been antidilutive. The shares convertible to common stock for Series 1, 3 and 4 preferred stock would have been 13,502 and 15,575 and 4,920, respectively, as of February 2, 2013.
