Net Income Per Share Attributable To Quest Software Inc. Stockholders

NOTE 12 — NET INCOME PER SHARE ATTRIBUTABLE TO QUEST SOFTWARE INC. STOCKHOLDERS

Basic net income per share is computed by dividing net income attributable to Quest Software Inc. stockholders by the weighted-average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution of securities by including other common stock equivalents, including stock options and restricted stock units, in the weighted–average number of common shares outstanding for a period, if dilutive.

The table below sets forth the reconciliation of the denominator of the net income per share attributable to Quest Software, Inc. stockholders (in thousands):

	Three Months Ended March  31
	2012		2011
Shares used in computing basic net income per share		83,424		92,303
Dilutive effect of stock options and restricted stock units (1)		1,678		2,809
Shares used in computing diluted net income per share		85,102		95,112

(1) Options to purchase 4.9 million and 1.3 million shares of common stock were outstanding during the three months ended March 31, 2012 and 2011, respectively, but were not included in the computation of diluted net income per share as inclusion would have been anti-dilutive.
