NET LOSS PER SHARE

We calculate basic net loss per share by dividing earnings allocated to common stockholders by the basic weighted average number of common shares outstanding for the period.

Diluted weighted average shares is computed using basic weighted average number of common shares outstanding plus any potentially dilutive securities outstanding during the period using the treasury-stock-type method and the if-converted method, except when their effect is anti-dilutive. Potentially dilutive securities include stock options, restricted stock units, the Upfront Warrants held by Total, and the outstanding senior convertible debentures.

The following table presents the calculation of basic and diluted net loss per share attributable to stockholders:



	Fiscal Year Ended
(In thousands, except per share amounts)	2018			2017			2016
Numerator:
Net loss attributable to stockholders	$	(811,091	)	$	(929,121	)	$	(448,635	)
Denominator¹:
Basic and diluted weighted-average common shares	140,825			139,370			137,985

Basic and diluted net loss per share attributable to stockholders	$	(5.76	)	$	(6.67	)	$	(3.25	)

¹As a result of our net loss attributable to stockholders for fiscal 2018, 2017 and 2016, the inclusion of all potentially dilutive stock options, restricted stock units, and common shares under noted warrants and convertible debt would be anti-dilutive. Therefore, those stock options, restricted stock units and shares were excluded from the computation of the weighted-average shares for diluted net loss per share for such periods.

The following is a summary of outstanding anti-dilutive potential common stock that was excluded from diluted net loss per share attributable to stockholders in the following periods:



	Fiscal Year Ended
(In thousands)	2018	2017	2016
Stock options	—	—	141
Restricted stock units	5,699	3,917	4,997
Upfront Warrants (held by Total)	9,532	364	3,721
4.00% debentures due 2023	13,922	13,922	13,922
0.75% debentures due 2018	4,975	12,026	12,026
0.875% debentures due 2021	8,203	8,203	8,203
