Note 17 - Earnings Per Share

Basic net income or loss per share is calculated by dividing net income or loss available to common stockholders by the basic weighted-average number of common shares outstanding for the respective period, which includes equity classified prefunded warrants. Equity classified prefunded warrants are included in the computation of the basic weighted-average number of common shares outstanding since the exercise price is negligible and all of the equity classified prefunded warrants are fully vested and exercisable.

Diluted net income or loss per share is calculated by dividing adjusted net income or loss by the diluted weighted-average number of common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for this calculation consist of warrants to purchase common stock that are either liability classified or equity classified, prefunded warrants to purchase common stock that are liability classified, stock options, unvested restricted stock and unvested restricted stock units (see Note 15 - Equity Incentive Plan and Note 16 - Warrants for further detail). If the Company’s adjusted numerator for net income from continuing operations divided by the diluted weighted-average number of common shares outstanding for each potentially dilutive security was greater than the net income from continuing operations per share, then the Company did not include those common equivalent shares in the computation of diluted net income or loss from continuing operations per share; diluted net income or loss from discontinued operations, net of tax; or diluted net income or loss per share because the effect would have been anti-dilutive.

The following is a reconciliation of the numerator and the denominator used in the basic per share calculations:

The following is a reconciliation of the numerator and the denominator used in the diluted per share calculations:

The following table sets forth securities that could be considered anti-dilutive, and therefore are excluded from the calculation of diluted weighted-average common shares outstanding and related per share calculations:
