2. Net Loss per Share Basic net loss per share (basic EPS) is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, less RSAs subject to forfeiture. Diluted net loss per share (diluted EPS) is computed by dividing net loss by the weighted-average number of common shares outstanding during the period, less RSAs subject to forfeiture, plus dilutive potential common shares. Diluted EPS is identical to basic EPS for all periods presented since potential common shares are excluded from the calculation, as their effect is anti-dilutive. Weighted-Average Shares Outstanding The following table sets forth the computation of basic and diluted net loss and the weighted-average number of shares used in computing basic and diluted net loss per share:
