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. There were no potential dilutive common shares and there were no anti-dilutive shares for the three and nine month periods ended September 30, 2020 and 2019.

Basic earnings per unit (“EPU”) is computed using the two-class method. The two-class method is required when either (i) participating securities or (ii) multiple classes of common stock exists. The Operating Partnership’s special common units, and common units issued upon the conversion or redemption of special common units, meet the definition of participating securities as these units have the contractual right and obligation to share in the Operating Partnership’s net income (loss) and distributions. Under this approach net income (loss) attributable to common unitholders is reduced by the amount of distributions made (declared) to all common unitholders and by the amount of distributions that are required to be made (declared and undeclared) to special common unitholders. Distributed and undistributed earnings is subsequently divided by the weighted-average number of common and special common units outstanding for the period to compute basic EPU for each unit. Undistributed losses are allocated 100 percent to common units, other than common units issued upon the conversion or redemption of special common units. The special common units, and common units issued upon the conversion or redemption of special common units, only participate in undistributed losses in the event of a liquidation. Diluted EPU is computed by considering either the two-class method or the if-converted method, whichever results in more dilution. The if-converted method assumes the issuance of common units for all potential dilutive special common units outstanding. Due to the loss position (negative earnings) of the Operating Partnership for the three and nine month periods ended September 30, 2020 and 2019 all special common units, and common units issued upon the conversion or redemption of special common units, are antidilutive. The calculation of diluted EPU through the if-converted method would reduce the loss per share (as a result of an increase number of shares in the denominator) for the common units. Therefore in a loss position diluted EPU is equal to basic EPU. There were no potential dilutive common units and there were no anti-dilutive units other than the special common units, and common units issued upon the conversion or redemption of special common units, outstanding for the three and nine month periods ended September 30, 2020 and 2019.

The following table presents basic and diluted EPU for common and special common units for the three-month and nine-month periods ended September 30, 2020 and 2019.
