NET INCOME (LOSS) PER SHARE

The Company calculates net income (loss) per share by dividing earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period.

Diluted weighted average shares is computed using basic weighted average shares 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, warrants associated with the CSO2015, and the outstanding senior convertible debentures.

The following table presents the calculation of basic and diluted net income (loss) per share:



	Three Months Ended
(In thousands, except per share amounts)	April 3, 2016			March 29, 2015
Basic net income (loss) per share:
Numerator
Net income (loss) attributable to stockholders	$	(85,409	)	$	(9,581	)
Denominator
Basic weighted-average common shares	137,203			132,033

Basic net income (loss) per share	$	(0.62	)	$	(0.07	)

Diluted net income (loss) per share:
Numerator
Net income (loss) attributable to stockholders	$	(85,409	)	$	(9,581	)
Add: Interest expense incurred on the 4.00% debentures due 2023, net of tax	—			n/a
Add: Interest expense incurred on the 0.75% debentures due 2018, net of tax	—			—
Add: Interest expense incurred on the 0.875% debentures due 2021, net of tax	—			—
Net income (loss) available to common stockholders	$	(85,409	)	$	(9,581	)

The Upfront Warrants allow Total to acquire up to 9,531,677 shares of the Company's common stock at an exercise price of $7.8685. The warrants under the CSO2015, when such warrants were still outstanding, entitled holders to acquire up to 11.1 million shares of the Company's common stock at an exercise price of $24.00. During the second quarter of fiscal 2015, the Company entered into unwind agreements pursuant to which the Company issued common stock to settle all of the outstanding warrants relating to the CSO2015 (refer to "Note 12. Debt and Credit Sources" in our Annual Report on Form 10-K for the fiscal year ended January 3, 2016).

Holders of the Company's 4.00% debentures due 2023, 0.875% debentures due 2021, and 0.75% debentures due 2018 can convert the debentures into shares of the Company's common stock, at the applicable conversion rate, at any time on or before maturity. These debentures are included in the calculation of diluted net income per share if they were outstanding during the period presented and if their inclusion is dilutive under the if-converted method.

Holders of the Company's 4.50% debentures due 2015 could, under certain circumstances at their option and before maturity, convert the debentures into cash, and not into shares of the Company's common stock (or any other securities). Therefore, the 4.50% debentures due 2015 are excluded from the net income per share calculation. In March 2015, the 4.50% debentures due 2015 matured and were settled in cash (refer to "Note 12. Debt and Credit Sources" in our Annual Report on Form 10-K for the fiscal year ended January 3, 2016).

The following is a summary of outstanding anti-dilutive potential common stock that was excluded from income (loss) per diluted share in the following periods:



	Three Months Ended
(In thousands)	April 3, 2016¹	March 29, 2015¹
Stock options	149	190
Restricted stock units	3,816	3,616
Upfront Warrants (held by Total)	6,367	6,908
Warrants (under the CSO2015)	n/a	11,096
4.00% debentures due 2023	13,922	n/a
0.75% debentures due 2018	12,026	12,026
0.875% debentures due 2021	8,203	8,203

As a result of the net loss per share for the three months ended April 3, 2016 and March 29, 2015, 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 period.
