Earnings Per Share [Abstract] |
Net Loss Per Share | Note 12. Net Loss Per Share Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding adjusted to give effect to potentially dilutive securities. Restricted stock and unit awards, and stock options have not been included in the diluted loss per share calculation as their inclusion would have had an anti-dilutive effect. The potential common stock equivalents that have been excluded from the computation of diluted loss per share consist of the following:
