Earnings Per Share [Abstract] |
Loss per Share |
7. | Loss per Share
Basic per share data is computed by dividing net income or loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted per share data is computed by dividing net income or loss applicable to common stockholders by the weighted average number of common shares outstanding during the period increased to include, if dilutive, the number of additional common shares that would have been outstanding as calculated using the treasury stock method. Potential common shares were related to outstanding but unexercised options, multiple series of preferred stock, and warrants for all periods presented. We have excluded all potentially dilutive securities from the calculation of diluted loss per share attributable to common stockholders as of June 30, 2018 and 2017, as their inclusion would be antidilutive. Potentially dilutive common shares excluded from the calculations of diluted loss per share were 2.7 million as of June 30, 2018, which includes 2.2 million outstanding warrants and 0.2 million options, 0.3 million shares of preferred stock, and restricted stock awards. Potentially dilutive common shares excluded from the calculation of diluted loss per share were 0.5 million as of June 30, 2017.
