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 September 30,		Nine Months Ended September 30,
	2012	2011	2012	2011
Denominator – basic	158,689	148,363	152,721	148,264
Stock options	—	—	2	4
Deemed shares related to deferred compensation arrangements	42	42	42	42
Denominator – diluted	158,731	148,405	152,765	148,310

The dilutive effect of stock options of 34 and 14 shares for the three and nine month periods ended September 30, 2011, respectively, were excluded from the computations of diluted EPS because the effect of including the stock options would have been anti-dilutive. There were no anti-dilutive shares for the three and nine months ended September 30, 2012.

See Note 5 related to an issuance of common stock in the second quarter of 2012.

See Note 15 related to issuance of common stock subsequent to September 30, 2012.
