Earnings Per Share [Abstract]

Reconciliation of the basic and diluted net loss per share computations

A reconciliation of the basic and diluted net loss per share computations for the three months ended March 31, 2015 and 2014 is as follows (in thousands, except per share data):

	For the three months ended March 31,
	2015			2014
Numerator:
Net loss	$	(80,196	)	$	(92,178	)
Denominator:
Average number of common shares outstanding(1)	74,336			62,601
Basic and diluted net loss per share	$	(1.08	)	$	(1.47	)

_______________________________________________________________________________

(1) Basic earnings per share is computed by dividing net loss by the average number of common shares outstanding during the reporting period. In periods of net loss, the number of shares used to calculate diluted earnings per share is the same as basic earnings per share; therefore, the effect of dilutive securities is zero for such periods. The weighted average number of stock options and restricted stock units outstanding for the three months ended March 31, 2015 and 2014 totaling 2,135,196 and 1,012,919, respectively, were excluded from the calculation above because their effect would have been anti-dilutive.
