Earnings Per Share [Abstract]  
Earnings Per Share
Earnings Per Share
Basic earnings per share is computed based on the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed based on the weighted-average number of common shares outstanding, plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares represent outstanding restricted stock units. As a result of the net loss in the current-year twenty-six week period, dilutive potential common shares were anti-dilutive. The components of basic and diluted earnings per share were as follows (in thousands, except per share data):
