Earnings per Share (EPS) [Abstract]

Earnings per Share (EPS)

Note 4.  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:

Options to purchase 1,181,945 shares and 748,754 shares of common stock for the three-month periods ended March 29, 2020 and March 31, 2019, 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.
