Net Loss Per Share

15. Net Loss Per Share

Basic net loss per share amounts have been computed based on the weighted-average number of common shares outstanding. Diluted net loss per share amounts have been computed based on the weighted-average number of common shares outstanding plus the dilutive effect of potential common shares. The computation of potential common shares has been performed using the treasury stock method. Because of the net loss reported in each period, diluted and basic net loss per share amounts are the same.

The calculation of net loss and the number of shares used to compute basic and diluted earnings per share for the three-month and six-month periods ended June 30, 2013 and 2012 are as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
In thousands, except per share data	2013			2012			2013			2012
Net loss	$	(68,985	)	$	(51,312	)	$	(133,655	)	$	(107,206	)
Net loss per share – basic and diluted	$	(0.37	)	$	(0.31	)	$	(0.74	)	$	(0.66	)
Weighted average shares – basic and diluted		184,726			165,848			181,651			163,409

For the three-month and six-month periods ended June 30, 2013 and 2012, the following potentially dilutive securities were not included in the computation of net loss per share because the effect would be anti-dilutive:
