Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding.


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

Of the options outstanding of 1,536,887 and 1,499,373 for the three-month periods ended April 3, 2022 and April 4, 2021, respectively, options to purchase 732,874 shares and 558,734 shares of common stock for the three-month periods ending April 3, 2022 and April 4, 2021, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares.
