(1) Earnings allocated to the exchangeable OP units not held by the Parent have been included in the numerator and exchangeable common units have been included in the denominator for the purpose of computing diluted earnings per share for all periods as the per share and unit amount is the same.

(2) In March 2015, the exchangeable debt was settled primarily through the issuance of common stock. The adjustment in 2015 assumes the exchange occurred on January 1, 2015.

(3) Our total potentially dilutive shares and units outstanding for the years ended December 31 consisted of the following:

	2017		2016		2015
Total weighted average potentially dilutive limited partnership units		10,010		10,610		3,898
Total potentially dilutive stock awards		9,183		8,444		7,299
