Earnings Per Share [Abstract] |
Computation of Basic and Diluted Net Loss Per Common Share | 9. Computation of Basic and Diluted Net Loss Per Common Share Basic and diluted net loss per share is based upon the weighted average number of common shares outstanding during the period. Common stock equivalents consist of incremental common shares issuable upon the exercise of stock options, and the release (vesting) of restricted stock units and awards and are calculated under the treasury stock method. Common stock equivalent shares from unexercised stock options, and unvested restricted stock units and awards are excluded from the computation for periods in which we incur a net loss or if the exercise price of such options is greater than the average market price of our common stock for the period as their effect would be anti-dilutive. For the three months ended September 29, 2018 and September 30, 2017, potential shares from stock options, RSUs and Restricted Stock Awards (“RSAs”) totaling 1,436,320 and 842,775 shares, respectively, were excluded from the computation of diluted weighted average shares outstanding. For the nine months ended September 29, 2018 and September 30, 2017, potential shares from stock options, RSUs and RSAs totaling 1,253,843 and 868,198 shares, respectively, were excluded from the computation of diluted weighted average shares outstanding. A reconciliation of the numerator and denominator of basic and diluted net loss per common share is provided as follows:
