Earnings Per Share [Abstract] |
Loss Per Share | Loss Per Share Basic loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted loss per common share is calculated by dividing net 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, 2016 and 2015, since including them would have an anti-dilutive effect on loss per share due to the net loss 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 and 0.8 million restricted stock units for the three months ended March 31, 2016 and 1.5 million stock options and 0.4 million restricted stock units for the three months ended March 31, 2015. Basic and diluted loss per common share are as follows (in thousands, except per share data):
