Earnings Per Share

Basic earnings per share (“basic EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the reporting period. Diluted earnings per share (“diluted EPS”) gives effect to all dilutive potential shares outstanding resulting from employee stock options, restricted stock units, performance share units and stock appreciation rights ("SARs") during the period. The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2018 and 2017:



	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Net income	$	8,719	$	6,139	$	19,376	$	1,594

Basic – weighted average shares outstanding	28,075		27,891		28,059		27,894

Effect of dilutive potential securities	771		248		680		192

Diluted – weighted average shares outstanding	28,846		28,139		28,739		28,086

Net income (per share)
Basic	$	0.31	$	0.22	$	0.69	$	0.06
Diluted	0.30		0.22		0.67		0.06

The shares used in the calculation of diluted EPS exclude options and SARs to purchase shares where the exercise price was greater than the average market price of common shares for the period and the effect of the inclusion would be anti-dilutive. Such shares aggregated approximately 0.8 million and 0.5 million for the three and six months ended June 30, 2018, respectively, and approximately 1.4 million and 2.0 million for the three and six months ended June 30, 2017.
