Earnings Per Share [Abstract]  
Earnings per Common Share
EARNINGS PER COMMON SHARE
We determine “Basic earnings per share” using the two-class method as our unvested restricted share awards have non-forfeitable rights to dividends, and are therefore considered participating securities. We compute basic earnings per share by dividing net income attributable to the controlling interest less the allocation of undistributed earnings to unvested restricted share awards by the weighted-average number of common shares outstanding for the period.
We also determine “Diluted earnings per share” under the two-class method with respect to the unvested restricted share awards. We further evaluate any other potentially dilutive securities at the end of the period and adjust the basic earnings per share calculation for the impact of those securities that are dilutive. Our diluted earnings per share calculation includes the dilutive impact of employee stock options based on the treasury stock method and our incentive share awards with performance or market conditions under the contingently issuable method. The diluted earnings per share calculation also considers our operating partnership units under the if-converted method.

The computations of basic and diluted earnings per share for the three and six months ended June 30, 2013 and 2012 were as follows (in thousands, except per share data):
