7. Net Loss Per Share of Common Stock
Diluted loss per share is the same as basic loss per share for all periods presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss. Basic loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding.
The following table sets forth the computation of basic and diluted loss per share for common stockholders:
