Earnings Per Share

3 Months Ended

Mar. 31, 2017

Basic net income (loss) per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period. Diluted EPS is calculated by adjusting weighted average shares outstanding for the dilutive effect of potential common shares, determined using the treasury-stock method. For purposes of the diluted EPS calculation, stock options, restricted stock and restricted stock unit awards are considered to be potential common shares. During periods of net loss, no effect is given to potential common shares as they are anti-dilutive. Performance-based restricted stock units are not included in the calculation of diluted EPS until they are contingently issuable.

The basic and diluted EPS calculations for the three months ended March 31, 2017 and 2016 are presented below:



	Three Months Ended March 31,
(in thousands, except per share amounts)	2017		2016
Income (loss) attributable to common stockholders	$	3,744	$	(6,756	)

Weighted average common shares outstanding, basic	66,692		65,338
Effect of dilutive securities:
Restricted stock	83		—
Restricted stock units	178		—
Stock options	233		—
Weighted average common shares outstanding, diluted	67,186		65,338

Basic income (loss) per common share	$	0.06	$	(0.10	)
Diluted income (loss) per common share	$	0.06	$	(0.10	)

The following table provides the securities that could potentially dilute EPS in the future, but were not included in the computation of diluted EPS for the periods presented because to do so would have been anti-dilutive. The amounts included in this table exclude performance-based restricted stock units. The number of currently outstanding performance-based restricted stock units that are issued upon vesting could range from zero to a maximum of 364,652.
