Earnings Per Share [Abstract]

Net Income (Loss) Per Common Share

6.  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,
	2018		2017		2016
Weighted average common shares outstanding basic		33,426,855		30,222,289		29,750,378
Dilutive effect of stock options and restricted stock		—		340,357		217,534
Weighted average common shares outstanding diluted		33,426,855		30,562,646		29,967,912

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. Options to purchase 242,500 and 551,761 shares of common stock that were outstanding at December 31, 2017 and 2016, 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.
