Basic net (loss) income per share is computed using the weighted-average number of shares outstanding during the period. Diluted net (loss) income 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 per share follows:

	Three months ended
(amounts in thousands)	February 2, 2020		January 27, 2019
Weighted average common shares outstanding, basic		12,409		12,438
Dilutive effect of stock-based compensation		—		27
Weighted average common shares outstanding, diluted		12,409		12,465

During the three-months ended February 2, 2020, 10,793 shares of unvested common stock were not included in the computation of diluted earnings per share, as we incurred a net loss for that reporting period. During the three-months ended January 27, 2019, 723 shares of unvested common stock were not included in the computation of diluted earnings per share as their effect would be antidilutive.

	Nine months ended
(amounts in thousands)	February 2, 2020		January 27, 2019
Weighted average common shares outstanding, basic		12,405		12,488
Dilutive effect of stock-based compensation		16		105
Weighted average common shares outstanding, diluted		12,421		12,593

During the nine-months ended February 2, 2020, 5,853 shares of unvested common stock were not included in the computation of diluted earnings per share as their effect would be antidilutive. During the nine-months ended January 27, 2019, all unvested shares of common stock were included in the computation of diluted earnings per share.
