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 three months ended March 31, 2020 and 2019, since including them would have an anti-dilutive effect on loss per share due to the net loss incurred during the periods. Securities convertible into shares of common stock that were not considered in the diluted loss per share calculations were 0.4 million restricted stock units and 3.0 million stock options for the three months ended March 31, 2020 and 0.2 million restricted stock units for the three months ended March 31, 2019.
