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 and nine months ended September 30, 2017 and 2016, 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 1.3 million restricted stock units for the three and nine months ended September 30, 2017, and 0.7 million stock options and 0.8 million restricted stock units for the three and nine months ended September 30, 2016.

Basic and diluted earnings (loss) per common share are as follows (in thousands, except per share data):
