Net Income per Common Share

9.  Net Income per Common Share

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

	For the Quarter Ended June 30,				For the Six Months Ended June 30,
	2019		2018		2019		2018
Weighted average common shares outstanding basic		35,471,795		32,606,838		35,430,392		31,561,194
Dilutive effect of stock options and restricted stock		271,768		477,702		322,662		520,156
Weighted average common shares outstanding diluted		35,743,563		33,084,540		35,753,054		32,081,350

Options to purchase 643,813 and 648,313 shares of common stock that were outstanding for the quarter and six months ended June 30, 2019, respectively, and 252,132 for the six months ended June 30, 2018, were not included in the computation of diluted earnings per share as the exercise prices of these options were greater than the average market price of common shares, and were therefore anti-dilutive. There were no options to purchase shares of common stock excluded from the computation of diluted earnings per share for the quarter ended June 30, 2018.
