Earnings (Loss) Per Share

12 Months Ended

Dec. 28, 2021

Basic earnings (loss) per share (“EPS”) is calculated by dividing net income (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during each period. Diluted EPS is calculated using net income (loss) available to common stockholders divided by diluted weighted-average shares of common stock outstanding during each period. Potentially dilutive securities include shares of common stock underlying stock options and restricted common stock. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect.

The following table sets forth the computations of basic and diluted EPS (in thousands, except share and per share data):

The Company computes the effect of dilutive securities using the treasury stock method and average market prices during the period. Potential common shares are excluded from the computation of diluted earnings per share when the effect would be anti-dilutive. Shares issuable on the vesting or exercise of share based awards or exercise of outstanding warrants were excluded from the calculation of diluted loss per share because the effect of their inclusion would have been anti-dilutive totaled 503,142, 3,175,472 and 1,513,552 for 2021, 2020 and 2019, respectively.
