Earnings Per Share

9 Months Ended

Sep. 30, 2011

Basic earnings per share (“EPS”) is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS assumes the issuance of common stock for all potential dilutive common shares outstanding. The limited partners’ rights to convert their noncontrolling interests in the Operating Partnership into shares of common stock are not dilutive.

The following summarizes the impact of potential dilutive common shares on the denominator used to compute EPS:
