Earnings per Share and Earnings per Unit

Earnings per Share of the Company

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:

Denominator – diluted	170,792	170,494	170,731	170,457


(1)	Performance stock units are contingently issuable common shares and are included in earnings per share if the effect is dilutive. See Note 13 for a description of the long-term incentive program, which was adopted in 2015, that these units relate to.

Earnings per Unit of the Operating Partnership

Basic earnings per unit (“EPU”) is computed by dividing net income attributable to common unitholders by the weighted-average number of common units outstanding for the period. Diluted EPU assumes the issuance of common units for all potential dilutive common units outstanding.

The following summarizes the impact of potential dilutive common units on the denominator used to compute EPU:

Denominator – diluted	200,045	199,751	199,986	199,716


(1)	Performance stock units are contingently issuable common units and are included in earnings per unit if the effect is dilutive. See Note 13 for a description of the long-term incentive program, which was adopted in 2015, that these units relate to.
