Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share are calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share are calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards. Common stock equivalents are excluded from the computation if their effect is anti-dilutive. Diluted earnings per share are computed using the treasury stock method.

No anti-dilutive common stock equivalents were excluded from the computation for the years ended December 31, 2013 and 2012. Anti-dilutive common stock equivalents of approximately 2,000 shares were excluded from the computation for the year ended December 31, 2011.

The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the years ended December 31, 2013, 2012 and 2011 (in thousands, except per share data):
