NET LOSS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS

Basic net loss per share attributable to common stockholders ("EPS") excludes dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if the potential common shares had been issued.

The following table reconciles basic and diluted weighted average common shares outstanding for the three months ended March 31, 2014 and 2013 (in thousands, except for loss per share):

	Three Months Ended
	March 31,
	2014			2013
Weighted average common shares outstanding:
Basic	223,207			215,634
Dilutive common stock options (1)	—			—
Diluted	223,207			215,634
Basic and diluted net loss per share attributable to common stockholders	$	(0.44	)	$	(0.54	)

(1) Stock options and unvested stock of 14.5 million shares and 18.6 million shares for the three months ended March 31, 2014 and 2013, respectively, representing securities that could potentially dilute basic EPS in the future were not included in the diluted net loss per share computations because their effect would have been anti-dilutive.
