17. Net Income (Loss) Per Share

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


	Three months ended
(amounts in thousands)	January 27, 2019		January 28, 2018
Weighted average common shares outstanding, basic		12,438		12,436
Dilutive effect of stock-based compensation		27		—

Weighted average common shares outstanding, diluted		12,465		12,436

At January 27, 2019 and April 29, 2018, there were no options to purchase shares of our common stock outstanding. Therefore, options to purchase shares of our common stock were not included in the computation of diluted net income for the three-months ending January 27, 2019. Stock-based compensation awards totaling 160,743 shares of common stock were not included in the computation of diluted net loss per share for the three-months ending January 28, 2018, as we incurred a net loss for that reporting period.


	Nine months ended
(amounts in thousands)	January 27, 2019		January 28, 2018
Weighted average common shares outstanding, basic		12,488		12,425
Dilutive effect of stock-based compensation		105		201

Weighted average common shares outstanding, diluted		12,593		12,626

At January 27, 2019 and April 29, 2018, there were no options to purchase shares of our common stock outstanding. Therefore, options to purchase shares of our common stock were not included in the computation of diluted net income for the nine-months ending January 27, 2019. All options to purchase shares of common stock were included in the computation of diluted net income for the nine-months ending January 28, 2018, as the exercise price of the options was less than the average market price of the common shares.
