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. The components of basic and diluted earnings per share were as follows (in thousands, except per share data):

For the thirteen weeks ended August 4, 2018 and July 29, 2017, and the twenty-six weeks ended August 4, 2018, there were an immaterial number of additional shares issuable upon the vesting of restricted stock units that were excluded from the diluted share calculations because they were anti-dilutive.

For the twenty-six weeks ended July 29, 2017, all potential common shares were excluded from the diluted share calculation because they were anti-dilutive due to the net loss in the period.
