Net (Loss) Income per Share Attributable to Sterling Common Stockholders

Basic net (loss) income per share attributable to Sterling common stockholders is computed by dividing net (loss) income attributable to Sterling common stockholders by the weighted average number of common shares outstanding during the period. Diluted net (loss) income per common share attributable to Sterling common stockholders is the same as basic net (loss) income per share attributable to Sterling common stockholders but includes dilutive unvested stock and stock options using the treasury stock method. The following table reconciles the numerators and denominators of the basic and diluted per common share computations for net (loss) income attributable to Sterling common stockholders (amounts in thousands, except per share data):

		Three Months Ended June 30,								Six Months Ended June 30,
		2015				2014				2015				2014
Numerator:
Net (loss) income attributable to Sterling common stockholders		$	(2,542	)		$	1,200			$	(19,534	)		$	1,406

Denominator:
Weighted average common shares outstanding — basic			19,270				17,942				19,041				17,309
Shares for dilutive unvested stock and stock options			-				168				-				155
Weighted average common shares outstanding and incremental shares assumed repurchased— diluted			19,270				18,110				19,041				17,464
Basic and diluted (loss) earnings per share attributable to Sterling common stockholders		$	(0.13	)		$	0.07			$	(1.03	)		$	0.08

In accordance with the treasury stock method, no shares of unvested common stock and stock options were excluded from the diluted weighted average common shares outstanding for the three months ended June 30, 2015, as the assumed proceeds related to these shares would purchase more shares than the unvested shares outstanding resulting in anti-dilution.

In addition, and also in accordance with the treasury stock method, approximately 0.1 million shares were excluded from the diluted weighted average common shares outstanding for the six months ended June 30, 2015, as the Company incurred a loss during this period and the impact of such shares would have been antidilutive.
