Net loss per share is calculated using the weighted average number of shares of common stock outstanding during the applicable period. Basic weighted average common shares outstanding do not include shares of restricted stock that have not yet vested, although such shares are included as outstanding shares in the Company’s Consolidated Balance Sheet. Diluted net earnings per share is computed using the weighted average number of common shares outstanding and if dilutive, potential common shares outstanding during the period. Potential common shares consist of the additional common shares issuable in respect of restricted share awards, stock options and convertible preferred stock.

The following table presents the computation of basic and diluted net loss per share:

Potentially dilutive securities totalling 406,992 and 337,492, respectively, were excluded from the calculation of diluted net loss per share for the years ended January 2, 2021 and December 28, 2019 because the effects were anti-dilutive based on the application of the treasury stock method.
