Earnings Per Share [Abstract]

Earnings Per Share

10. Earnings Per Share

Basic loss per share is calculated by dividing the net loss attributable to controlling interests by the weighted average number of common shares outstanding during the period. Diluted loss per share adjusts basic loss per share for the effects of potentially dilutive common shares, if the effect is not antidilutive. Potentially dilutive common shares consist of shares issuable under our equity-based compensation plan and Operating Partnership units. For the three and six months ended June 30, 2011, 994,820 options to purchase common stock and 396,653 restricted shares have been excluded from the calculation of diluted earnings per share as their effect would have been antidilutive.
