Basic net (loss) income per share is based on the weighted-average number of shares of common stock outstanding for each of the periods presented. Net (loss) income per share, assuming dilution, is based on the weighted-average number of shares of common stock equivalents outstanding adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments. The Company's potentially dilutive instruments are made up of equity awards, which include stock options, restricted share units and performance share units. All potentially dilutive common shares were excluded from the diluted loss per share calculation for fiscal 2019, because the Company was in a net loss position and their effect would have been antidilutive
When calculating diluted net income per share, ASC 260 requires the Company to include the potential shares that would be outstanding if all outstanding stock options were exercised. This number would be different from outstanding stock options, because it is offset by shares the Company could repurchase using the proceeds from these hypothetical exercises to obtain the common stock equivalent.
Approximately 5.1 million, 1.4 million and 1.7 million of outstanding stock awards for fiscal 2019, 2018 and 2017, respectively, were excluded from the diluted (loss) income per share calculation because their effect was antidilutive.
