Net Loss Per Share

13. 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, if any, 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 years ended December 31, 2014, 2013 and 2012 are as follows:

In thousands, except per share amounts	2014			2013			2012
Net loss	$	(162,602	)	$	(274,158	)	$	(220,872	)
Weighted average shares outstanding – basic and diluted		186,835			183,575			164,964
Net loss per share – basic and diluted	$	(0.87	)	$	(1.49	)	$	(1.34	)

For the years ended December 31, 2014, 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:
