Basic net (loss) income from continuing operations per share is computed using the weighted-average number of shares outstanding during the period. Diluted net (loss) income from continuing operations per share uses the weighted-average number of shares outstanding during the period plus the dilutive effect of stock-based compensation calculated using the treasury stock method. Weighted average shares used in the computation of basic and diluted net (loss) income from continuing operations per share are as follows:

(in thousands)	2020		2019		2018
weighted-average common shares outstanding, basic		12,378		12,462		12,431
dilutive effect of stock-based compensation		—		86		202
weighted-average common shares outstanding, diluted		12,378		12,548		12,633

As of May 3, 2020, April 28, 2019, and April 29, 2018, there were no options outstanding to purchase shares of our common stock. Therefore, options to purchase shares of our common stock were not included in the computation of diluted net (loss) income from continuing operations per share during fiscal 2020 and 2019. However, we did have options to purchase shares of common stock during fiscal 2018 that were included in the computation of diluted net income from continuing operations per share, as the exercise price of the options was less than the average market price of common shares.

During fiscal 2020, 19,388 shares of unvested common stock were not included in the computation of diluted net loss from continuing operations per share as their effect would be antidilutive. During fiscal 2020, 45,731 shares of unvested common stock were not included in the computation of diluted net loss from continuing operations per share, as we incurred a net loss for the fiscal year, in which their effect would be anti-diluted. During fiscal 2019 and 2018, all unvested shares of common stock were included in the computation of diluted net income from continuing operations per share.
