Earnings Per Share [Abstract]  
Net Income (Loss) per Common Share
Net Income (Loss) per Common Share  

Basic net income (loss) per share was calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the period.  Diluted net income (loss) per share was calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the period plus the dilutive effects of options and restricted stock.  Due to the net loss in the thirty-nine weeks ended February 25, 2017, restricted shares in the amount of 145,044 were excluded from the calculation of diluted earnings per share because their inclusion would have been antidilutive.  The computations of basic and diluted net income (loss) per share attributable to the Company are as follows (in thousands, except per share data):
