Earnings per Share [Abstract]

Earnings (Loss) per Share

Note 3 .  Earnings per Share (EPS)

Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. 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 1,671,687 and 1,608,613 for the three-month periods ended March 31, 2024 and April 2, 2023, respectively, options to purchase 900,163 shares and 1,002,344 shares of common stock for the three-month periods ending March 31, 2024 and April 2, 2023, 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.
