(1) The years ended December 31, 2020, 2019 and 2018, include 157, 210, and 308 weighted-average, unvested, earned RSUs, respectively.

(2) Represents weighted-average number of common shares that would have been issued if the year-end was the measurement date for unvested, unearned RSUs.

(3) Represents the weighted-average dilutive shares issuable from LTIP Units if the year-end was the measurement date for the periods shown.

(4) The Series D preferred shares are excluded from the diluted earnings per share calculation for the year ended December 31, 2018 because including the Series D preferred shares would also require that the preferred distributions be added back to net income, resulting in anti-dilution.

(5) Beneficial interests in the Operating Trust.
