Earnings per Share

The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended June 30,					Six Months Ended June 30,
	2018			2017		2018		2017
	(in thousands, except per share data)
Numerator:

Net income	$	(10,554	)	$	7,195	$	225	$	20,885
Denominator for basic earnings per share - weighted-average common shares outstanding		165,162			162,357		164,812		158,259
Effect of dilutive securities: Stock options, restricted shares and performance based shares		-			1,448		2,903		1,683
Denominator for diluted earnings per share - adjusted weighted-average shares and assumed exercise of options, restricted shares and performance based shares		165,162			163,805		167,715		159,942

Net (loss) income per common share - basic	$	(0.06	)	$	0.04	$	0.00	$	0.13

Net (loss) income per common share - diluted	$	(0.06	)	$	0.04	$	0.00	$	0.13

Basic net (loss) income per share, excluding any dilutive effects of stock options, unvested restricted stock and unvested performance based shares, is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per share is computed in a manner similar to basic; however diluted net income per share reflects the assumed conversion of all potentially dilutive securities. For the

three

months ended

June 30, 2018,

3.2

million shares relating to stock options, unvested restricted shares and unvested performance based restricted shares were excluded from the calculation of diluted loss per share since their inclusion would have been anti-dilutive due to the loss incurred in the period.
