Net Income Per Share

Net Income Per Share

Basic net income per share is computed by dividing the net income available to common stockholders for the period by the weighted average number of shares of common stock outstanding during the period less shares of common stock subject to repurchase and nonvested stock awards. Diluted net income per share is computed by dividing the net income for the period by the weighted average number of shares of common stock and potential shares of common stock outstanding during the period if their effect is dilutive under the treasury stock method.

The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share data):

	Year Ended November 30,
	2012		2011		2010
Net income attributable to TIBCO Software Inc.	$	122,007	$	112,406	$	78,088
Weighted-average shares of common stock used in computing basic net income per share (excluding unvested restricted stock)	160,330		161,469		160,959
Effect of dilutive common stock equivalents:
Stock options	6,677		9,549		7,949
Stock awards	2,683		2,245		2,042
ESPP	8		9		3
Weighted-average shares of common stock used in computing diluted net income per share	169,698		173,272		170,953
Net Income per share attributable to TIBCO Software Inc.:
Basic net income per share	$	0.76	$	0.70	$	0.49
Diluted net income per share	$	0.72	$	0.65	$	0.46

The following potential weighted-average common stock equivalents are not included in the diluted net income per share calculation above, because their effect was anti-dilutive for the periods indicated (in thousands):

	Year Ended November 30,
	2012	2011	2010
Stock options	1,738	1,264	4,487
Stock awards	291	404	76
Convertible senior notes	7,542	—	—
Total anti-dilutive common stock equivalents	9,571	1,668	4,563

Anti-dilutive potential common stock equivalents for fiscal year 2012 include the weighted effect of the 11.9 million shares that could be issued under the Notes if we experience a substantial increase in our common stock price. Under the treasury stock method, the Notes will generally have a dilutive impact on net income per share if our average stock price for the period exceeds the conversion price for the Notes. On conversion of a Note, however, we will deliver cash in an amount generally equal to the lesser of the conversion value and the principal amount of each Note and, only for any conversion value greater than the principal amount, we will deliver shares of common stock.
