Net income (loss) per share is presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic net income (loss) per share is computed by dividing earnings available to common shareholders by the weighted average shares of common stock outstanding during the period. For the purposes of calculating diluted net income (loss) per share, the denominator includes both the weighted average number of shares of common stock outstanding during the period and the weighted average number of shares of potential dilutive shares of common stock, such as stock awards, calculated using the treasury stock method. Basic and diluted net income (loss) per share was the same for fiscal 2017 and 2016 as the impact of potential dilutive shares outstanding was anti-dilutive.

The following table sets forth our computation of basic and diluted net income (loss) per common share (amounts in thousands, except per share data):

The number of common shares used in the computation of diluted net income (loss) per share for the periods presented does not include the effect of the following potentially outstanding common shares because the effect would have been anti-dilutive (amounts in thousands):
