Earnings Per Share [Abstract] |
Earnings (Loss) Per Share | Earnings (Loss) Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding combined with dilutive common share equivalents outstanding, if the effect is dilutive. Potentially dilutive securities were excluded from the calculation of diluted loss per share for the year ended December 31, 2017, since including them would have an anti-dilutive effect on loss per share due to the loss from continuing operations incurred during the period. Securities convertible into shares of common stock that were not considered in the diluted loss per share calculations were 0.7 million stock options, before they were converted into common shares during 2017, and 0.7 million restricted stock units. Basic and diluted earnings (loss) per common share are as follows (in thousands, except per share data):
