[1] Adjustments for stock options and awards of 61 shares and 329 shares and deferred compensation arrangements of 12 shares and 11 shares were anti-dilutive in fiscal 2012 and 2011, respectively. These shares were therefore excluded from the earnings per share calculation due to our net loss for the years.
