NOTE 2—NET LOSS PER COMMON SHARE

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of vested common shares outstanding during the period. Diluted net loss per common share is computed by giving effect to all potential dilutive common shares, including outstanding options, common stock subject to repurchase and warrants. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per common share follows (in thousands):
