Basic and Diluted Net Income (Loss) Per Share

For the three and nine months ended September 30, 2019 and 2018, basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income per common share is calculated to give effect to all dilutive securities, if applicable, using the treasury stock method. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.

The following table sets forth the reconciliation of shares used to compute basic and diluted net (loss) income per share for the periods indicated (in thousands):

The computation of diluted earnings per share excludes stock options and stock units that are anti-dilutive. The following common stock equivalents were anti-dilutive (in thousands):
