Earnings Per Share [Abstract] |
Basic and Diluted Net Loss Per Share | NOTE 4—BASIC AND DILUTED NET LOSS PER SHARE Basic net loss per share has been computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is calculated by dividing net loss by the weighted-average number of shares of common stock and potential dilutive securities outstanding during the period. The total number of shares subject to stock options and restricted stock units outstanding, which are all anti-dilutive, were excluded from consideration in the calculation of diluted net loss per share. Stock options and restricted stock units outstanding as of June 30, 2018 and 2017 were 8,702,199 and 9,898,588, respectively.
