13. Net Loss Per Share

Net loss per share is presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic net 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 earnings 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 options and RSUs, calculated using the treasury stock method. Basic and diluted net loss per share was the same for the periods presented as the impact of potential dilutive shares outstanding was anti-dilutive.

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

We did not include the securities described in the following table in the computation of diluted net loss per share for the periods presented. These exclusions are made if the exercise price of these common shares is in excess of the average market price of the common stock for the periods presented, which has an anti-dilutive effect (amounts in thousands):
