Effect of dilutive employee stock options and restricted stock units	863		575		162
Diluted weighted-average shares outstanding	26,778		25,043		23,852
Net income per share—basic	$	1.51	$	0.69	$	0.09
Net income per share—diluted	$	1.47	$	0.67	$	0.09

For the year ended December 31, 2011, a total of 1.1 million shares of common stock subject to options and restricted stock units were excluded from the computation of diluted net income per share as the resulting effect would have been anti-dilutive, compared to 1.5 million shares and 3.7 million shares for the years ended December 31, 2010 and 2009, respectively. Options and restricted stock units are anti-dilutive when we have a net loss or when the exercise price of the stock option and the average unrecognized compensation cost of the stock option or restricted stock unit are greater than the average market price of our common stock.
