(10) Net Loss Per Share Attributable to Common Stockholders

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company’s convertible preferred stock that was outstanding prior to the closing of the IPO is considered a participating security with respect to the periods during which it was outstanding. Participating securities do not have a contractual obligation to share in the Company’s losses. As such, for the periods the Company incurs net losses, there is no impact on the calculated net loss per share attributable to common stockholders in applying the two-class method.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, participating securities, stock options to purchase common stock, RSUs, warrants to purchase common stock and convertible preferred stock are considered to be common stock equivalents and have been excluded from the calculation of diluted net loss per share attributable to common stockholders, as their effect is antidilutive.

The computation of basic and diluted net loss per share attributable to common stockholders is as follows (in thousands, except share and per share data):
