NET LOSS PER SHARE
 
We compute net loss per share based on the weighted average number of common shares outstanding for the period.  Diluted net loss per share reflects the maximum dilution that would have resulted from incremental common shares issuable upon the exercise of stock options.  We compute the number of common share equivalents, which includes stock options, using the treasury stock method. We have excluded stock options to acquire approximately 2,063,000 and 1,568,000 shares for the three and nine months ended September 30, 2019 and September 30, 2018, respectively, from the computation of the dilutive stock options because the effect of including the stock options would have been anti-dilutive.

The following table sets forth the computation of basic and diluted net income (loss) per common share for the three and nine months ended September 30, 2019 and September 30, 2018:
