Net Loss Per Share
4.  Net Loss Per Share

Basic net loss per share amounts have been computed by dividing net loss by the weighted-average number of common shares outstanding during the period. For each of the periods presented below, we reported net losses and, accordingly, potential dilutive common shares were not included in the computation of diluted net loss per share since it would have been anti-dilutive. The calculations of net loss per share, basic and diluted, are as follows:
