Net loss used for basic calculation		$	(16,863	)		$	(9,460	)
Effect of revaluation of warrant liability			—				(6,296	)
Adjusted net loss used for diluted calculation		$	(16,863	)		$	(15,756	)
Denominator:
Basic weighted average number of shares outstanding			99,471				93,411
Effect of dilutive potential shares			—				1,251
Diluted weighted average number of shares outstanding			99,471				94,662
Net loss per share:
Basic		$	(0.17	)		$	(0.10	)
Diluted		$	(0.17	)		$	(0.17	)

Anti-Dilutive Effect of Common Shares

The table below presents shares underlying stock options, employee stock purchase plan rights, restricted stock units and/or convertible preferred stock that were excluded from the calculation of the weighted average number of shares outstanding used for the calculation of diluted net loss per share. These are excluded from the calculation due to their anti-dilutive effect for the three months ended March 31, 2016 and 2015 (shares in thousands):

		Three Months Ended March 31,
		2016				2015
Weighted average number of anti-dilutive potential shares—outstanding options			14,986				13,439

- Definition

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
