Earnings per Share

10. Earnings per Share

Basic earnings (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the effects of stock options, restricted common stock, warrants and other potentially dilutive financial instruments, only in the periods in which the effects are dilutive. The accounting standard pertaining to earnings per share precludes the calculation of diluted earnings per share when a net loss is presented. The following is a reconciliation of the weighted-average shares outstanding and calculation of basic and diluted earnings per share:

	Year Ended December 31,
	2011		2010		2009
	(In Thousands, Except for Per Share Data)
Net income (loss) attributable to XO Group Inc.	$	6,040	$	3,654	$	(4,874	)
Total weighted-average basic shares		29,060		32,768		32,092
Dilutive securities:
Restricted stock		491		507		—
Employee Stock Purchase Plan		10		10		—
Options/warrants		131		375		—
Total weighted-average diluted shares		29,692		33,660		32,092
Net income (loss) per share attributable to XO Group Inc. common shareholders:
Basic	$	0.21	$	0.11	$	(0.15	)
Diluted	$	0.20	$	0.11	$	(0.15	)

The calculation of diluted earnings per share excludes a weighted average number of stock options and restricted stock of 184,300, 161,119 and 233,585 for the years ended December 31, 2011, 2010 and 2009, respectively, because to include them in the calculation would be antidilutive.
