(1)

Income (loss) allocated to the exchangeable Operating Partnership units not held by the REIT has been included in the numerator and exchangeable Operating Partnership units have been included in the denominator for the purpose of computing diluted earnings per share for all periods since the per share/unit amount is the same. Weighted average exchangeable Operating Partnership units outstanding (in thousands) were 1,859 and 1,900 for the three months ended September 30, 2013 and 2012, respectively and were 1,882 and 1,973 for the nine months ended September 30, 2013 and 2012, respectively.

(2)	The increase in shares/units between the periods is due to an equity offering in April 2013. See Note 8 for more information.

(3)

Total weighted average potentially dilutive stock awards and warrants outstanding (in thousands) were 14,133 and 9,633 for the three months ended September 30, 2013 and 2012, respectively, and 14,070 and 9,824 for the nine months ended September 30, 2013 and 2012, respectively. Total weighted average potentially dilutive shares/units from exchangeable debt outstanding (in thousands) were 11,879 for all periods presented. Total weighted average potentially dilutive limited partnership units outstanding (in thousands) were 1,950 and 1,285 for the three months ended September 30, 2013 and 2012, respectively and 1,426 and 1,287 for the nine months ended September 30, 2013 and 2012, respectively.
