Earnings Per Share [Text Block]

7.

Net Income (Loss) per Common Share

Basic earnings per share is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated using the weighted average number of common shares outstanding plus dilutive common stock equivalents outstanding as determined by the treasury method during the period. In periods when we have a net loss, common stock equivalents are excluded from our calculation of earnings per share as their inclusion would have an antidilutive effect. For the

three

month period ended

March 31, 2019,

we excluded a nominal amount of unvested stock awards from our calculation of diluted weighted average shares because they were antidilutive. For the

three

month period ended

March 31, 2018,

we excluded

3.3

million common stock options,

6.7

million warrants, and

338,000

unvested stock awards from our calculation of diluted weighted average shares because they were antidilutive.

The following table shows the calculation of basic and diluted earnings per shares:
