Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income 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:

	Three Months Ended June 30,		Six Months Ended June 30,
	2012	2011	2012	2011
Denominator – basic	150,913	148,356	149,704	148,214
Stock options	—	1	—	7
Deemed shares related to deferred compensation arrangements	41	41	42	41
Denominator – diluted	150,954	148,398	149,746	148,262

The dilutive effect of stock options of 2 and 6 shares for the six months ended June 30, 2012 and 2011, respectively. were excluded from the computations of diluted EPS because the effect of including the stock options would have been anti-dilutive. The dilutive effect of stock options of 3 shares for the three months ended June 30, 2011 was excluded from the computation of diluted EPS because the effect of including the stock options would have been anti-dilutive.
