Weighted average shares used to calculate net loss per share, diluted	36,789			34,699			28,805
Net loss per share:
Basic	$	(0.40	)	$	(0.79	)	$	(1.72	)
Diluted	$	(0.40	)	$	(0.79	)	$	(1.72	)

(A) The following as-if converted shares associated with the Company’s 2015 convertible senior notes were excluded from the calculation as their effect would be anti-dilutive (in thousands):

	For the Years Ended December 31,
	2015	2014	2013
2015 convertible senior notes	—	2,110	2,110

(B) The following shares, by equity award type, were excluded from the calculation, as their effect would have been anti-dilutive (in thousands):

	For the Years Ended December 31,
	2015	2014	2013
Stock options	2,966	2,841	3,465
Restricted stock units	151	128	335
Performance based restricted stock units (C)	1,625	240	193
Total equity award shares excluded	4,742	3,209	3,993

(C) 2014 and 2013 performance based restricted stock units are presented based on attainment of 100% of the performance goals being met. The maximum multiplier for a given semi-annual performance period is 2.75x the original grant and overall achievement is limited to a maximum of 2.5x of the target award over the entire performance period (Note 16 - Employee Benefit Plans). Based on this formula, the maximum number of shares that could be earned was 0.6 million and 0.5 million for the years ended December 31, 2014 and 2013. The 2015 performance based restricted stock units do not have a multiplier feature (Note 16 - Employee Benefit Plans) and are presented based on attainment of 100% of the performance goals being met.
