3. Net Income/(Loss) Per Share

The computation of basic and diluted net income/(loss) per share was as follows (in thousands, except per share data):


	Three Months Ended					Nine Months Ended
	March 31,					March 31,
	2014			2013		2014		2013
Numerator:
Net income/(loss)	$	(40,056	)	$	36,446	$	12,217	$	53,613

Denominator:
Shares, basic		35,685			32,234		34,212		32,552
Effect of dilutive share-based awards		—			1,901		2,320		1,291

Shares, diluted		35,685			34,135		36,532		33,843

Net income/(loss) per share:
Basic	$	(1.12	)	$	1.13	$	0.36	$	1.65

Diluted	$	(1.12	)	$	1.07	$	0.33	$	1.58

Our basic net income/(loss) per share amounts for each period presented have been computed using the weighted average number of shares of common stock outstanding. Our diluted net income/(loss) per share amounts for each period presented include the weighted average effect of potentially dilutive shares. We use the “treasury stock” method to determine the dilutive effect of our stock options, deferred stock units, or DSUs, market stock units, or MSUs, and convertible notes.

Dilutive net income/(loss) per share amounts do not include the weighted average effect of 2,481,307 share-based compensation awards and convertible notes outstanding, and shares issuable for settlement of contingent consideration determined to be payable during the three months ended March 31, 2014, 1,055,896 share-based awards that were outstanding during the three months ended March 31, 2013, and 356,878 and 3,025,632 share-based awards that were outstanding during the nine months ended March 31, 2014 and 2013, respectively. These share-based awards were not included in the computation of diluted net income/(loss) per share because their effect would have been antidilutive.
