(1)	The three months ended March 31, 2018 and 2017, includes 307 and 0 weighted-average, unvested, measured RSUs, respectively.


(2)	Represents weighted-average number of common shares that would have been issued if the quarter-end was the measurement date for RSUs and performance-based LTIPs.


(3)	Represents weighted-average time-based and performance-based LTIPs that would have been issued if the quarter-end was the measurement date for the periods shown.


(4)	Beneficial interests in the Operating Trust.


(5)	The Series D preferred shares are excluded from the diluted earnings per share calculation for the three months ended March 31, 2017 because including the Series D preferred shares would also require that the preferred distributions be added back to net income, resulting in anti-dilution
