Earnings Per Share

6 Months Ended

Jun. 30, 2019

The computation of basic and diluted earnings per share ("EPS") is based on Net income divided by the basic weighted average number of common shares and diluted weighted average number of common shares, respectively. The details of the basic and diluted EPS calculations for the three and six months ended June 30, 2019 and 2018 were as follows:


	Three Months Ended June 30,						Six Months Ended June 30,
	2019		2018		2019		2018
Basic
Net Income	$	15,346	$	28,410	$	35,520	$	40,003
Weighted average common shares outstanding	28,162,007		30,481,627		28,489,486		30,485,095
EPS – Basic	$	0.54	$	0.93	$	1.25	$	1.31
Diluted
Dilutive effect of equity awards and other stock-based holdings	974,972		823,541		970,663		809,228
Weighted average common shares outstanding	29,136,979		31,305,168		29,460,149		31,294,323
EPS – Diluted	$	0.53	$	0.91	$	1.21	$	1.28

Diluted EPS is computed based upon the weighted average number of common shares outstanding for the period plus the dilutive effect of common stock equivalents (which includes units allocated to the AdvanSix stock unit fund under the AdvanSix Inc. Deferred Compensation Plan) using the treasury stock method and the average market price of our common stock for the year.

The diluted EPS calculations exclude the effect of stock options when the options’ assumed proceeds exceed the average market price of the common shares during the period. For the three months ended June 30, 2019 and 2018, stock options of 539,054 and 128,777, respectively, were anti-dilutive and excluded from the computations of dilutive EPS.
