The number of shares used to calculate basic net income per common share is based on the weighted average number of the Company’s outstanding common shares during the respective period. The number of shares used to calculate diluted net income per common share is based on the number of common shares used to calculate basic net income per common share plus the dilutive effect of stock options and other stock-based instruments held by the Company’s employees and directors during the period, and the Company’s outstanding warrants. The dilutive effect of outstanding stock-based instruments is determined by application of the treasury stock method. The stock options and warrants become dilutive for diluted net income per common share calculations when the market price of the Company’s common stock exceeds the exercise price. Anti-dilution also occurs in periods of a net loss, and the dilutive impact of all warrants and share-based compensation awards are excluded.

For the years ended December 31, 2023, 2022, and 2021, respectively,1,240,0, and 717,992 warrants, stock options, and other stock-based instruments were excluded from the computation of dilutive net income per common share because they would have been anti-dilutive. When applying the treasury stock method, anti-dilution generally occurs when the exercise prices or unrecognized compensation cost per share are higher than the Company’s average stock price during an applicable period.

The following table presents the net income per common share for the years ended December 31, 2023, 2022, and 2021:
