7. EARNINGS PER SHARE

Basic earnings per share are computed by dividing net earnings by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share are computed by dividing net earnings by the sum of (a) the weighted average number of shares of common stock outstanding during the period and (b) the potentially dilutive securities outstanding during the period. Stock options are the only potentially dilutive securities; and the number of dilutive options is computed using the treasury stock method.

The following table sets forth the calculation of basic and diluted earnings per share:

Potentially dilutive securities, which were not included in the computation of diluted earnings per share, because either the effect would have been anti-dilutive or the options’ exercise prices were greater than the average market price of the common stock, were 397,000 and 175,000 for the 13 weeks ended May 29, 2022 and May 30, 2021, respectively.
