Basic and Diluted Net Income (Loss) per Share

BASIC AND DILUTED NET INCOME (LOSS) PER SHARE

We compute basic net income (loss) per share by dividing net income (loss) by the weighted average number of common shares outstanding during the relevant period. Diluted net income (loss) per common share has been computed by dividing net income (loss) by the diluted number of common shares outstanding during the period. Except where the result would be antidilutive to net income (loss), diluted net income (loss) per common share would be computed assuming the impact of the conversion of the $200.0 million of 2.5% convertible senior notes due February 15, 2019 (the “Convertible Notes”), the exercise of outstanding stock options, the vesting of restricted stock units (“RSUs”), and the exercise of warrants.

We have a choice to settle the conversion obligation under the Convertible Notes in cash, shares or any combination of the two. Pursuant to certain covenants in our six-year $350.0 million term loan facility (the “2015 Term Loan Facility”), which we entered into in 2015 to partially fund the acquisition of CBR, we may be restricted from settling the conversion obligation in whole or in part with cash unless certain conditions in the 2015 Term Loan Facility are satisfied. We utilize the if-converted method to reflect the impact of the conversion of the Convertible Notes. This method assumes the conversion of the Convertible Notes into shares of our common stock and reflects the elimination of interest expense related to the Convertible Notes when dilutive.

The dilutive effect of the warrants, stock options and RSUs has been calculated using the treasury stock method.

The components of basic and diluted net loss per share for the three months ended March 31, 2017 and 2016, were as follows (in thousands, except per share data):



	Three Months Ended March 31,
	2017			2016
Net loss	$	(36,560	)	$	(7,527	)

Weighted average shares outstanding used to compute net loss per share:
Basic	34,378			34,739
Diluted	34,378			34,739

Net loss per share:
Basic	$	(1.06	)	$	(0.22	)
Diluted	$	(1.06	)	$	(0.22	)

The following table sets forth the potential common shares issuable upon the exercise of outstanding options, the vesting of RSUs, the exercise of warrants (prior to consideration of the treasury stock method), and the conversion of the Convertible Notes, which were excluded from our computation of diluted net income (loss) per share because their inclusion would have been anti-dilutive (in thousands):



	Three Months Ended March 31,
	2017	2016
Options to purchase shares of common stock	2,406	2,455
Shares of common stock issuable upon the vesting of RSUs	775	904
Warrants	7,382	7,382
Convertible 2.5% notes	7,382	7,382
Total	17,945	18,123

In connection with the issuance of the Convertible Notes, in February 2014, we entered into convertible bond hedges. The convertible bond hedges are not included for purposes of calculating the number of diluted shares outstanding, as their effect would be anti-dilutive. The convertible bond hedges are generally expected, but not guaranteed, to reduce the potential dilution and/or offset the cash payments we are required to make upon conversion of the Convertible Notes.
