Earnings Per Share [Abstract]

Earnings (Loss) Per Common Share

Earnings (Loss) Per Common Share

Basic earnings (loss) per common share is computed by dividing net income (loss) attributable to Holdings' common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is computed by dividing net income (loss) attributable to Holdings' common stockholders by the weighted average number of common shares outstanding during the period and the effect of all dilutive common stock equivalents. In periods where there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive. These computations have been retroactively adjusted to reflect the 2011 Stock Split and the 2013 Stock Split as described in Note 12.

For the years ended December 31, 2013 and 2012, the computation of diluted earnings per share included the effect of 3.4 million and 3.3 million dilutive stock options and restricted stock units, respectively, and excluded the effect of 1.2 million and 1.9 million antidilutive stock options, respectively. Earnings per common share for the years ended December 31, 2013 and 2012 was calculated as follows:

	For the year ended December 31,
(Amounts in thousands, except per share amounts)	2013		2012
Net income attributable to Six Flags Entertainment Corporation common stockholders	$	118,552	$	365,935
Weighted average common shares outstanding—basic	96,940		107,684
Effect of dilutive stock options and restricted stock units	3,431		3,252
Weighted average common shares outstanding—diluted	100,371		110,936
Earnings per share—basic	$	1.22	$	3.40
Earnings per share—diluted	$	1.18	$	3.30

For the year ended December 31, 2011, we incurred a net loss and therefore diluted shares outstanding equaled basic shares outstanding as the computation of diluted shares outstanding excluded the effect of 11.4 million antidilutive stock options.

These share amounts have been retroactively adjusted to reflect the 2011 Stock Split and the 2013 Stock Split as described in Note 12.
