Net Income (Loss) Per Common Share

7.  Net Income (Loss) Per Common Share

Net income (loss) per common share, as shown on the accompanying Consolidated Statements of Operations, is determined on the basis of the weighted average number of common shares outstanding during the periods as follows:

	For the Year Ended December 31,
	2019		2018		2017
Weighted average common shares outstanding basic		35,491,958		33,426,855		30,222,289
Dilutive effect of stock options and restricted stock		161,189		—		340,357
Weighted average common shares outstanding diluted		35,653,147		33,426,855		30,562,646

Options to purchase 470,185 and 242,500 shares of common stock that were outstanding at December 31, 2019 and 2017, respectively, were not included in the computation of diluted earnings per share as the exercise prices of these options was greater than the average market price of common shares, and were therefore anti-dilutive. Due to the net loss for the year ended December 31, 2018, diluted weighted-average shares outstanding are equal to basic weighted-average shares outstanding because the effect of all equity awards is anti-dilutive.
