(1) The years ended December 31, 2022, 2021 and 2020, include 105, 256, and 157 weighted-average, unvested, earned RSUs, respectively.

(2) Represents the 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 years ended December 31, 2022 and 2021 because including the Series D preferred shares would also require that the preferred distributions be added back to net income, resulting in anti-dilution. The RSUs and market-based LTIP Units are excluded from the

diluted earnings per share calculation for the year ended December 31, 2021, because including them results in anti-dilution.

(5) Beneficial interests in the Operating Trust.
