(1) 2016 includes the dilutive impact of unvested restricted stock and shares issuable under the forward equity offering using the treasury stock method.
Income allocated to noncontrolling interests of the Operating Partnership has been excluded from the numerator and exchangeable Operating Partnership units have been omitted from the denominator for the purpose of computing diluted earnings per share since the effect of including these amounts in the numerator and denominator would have no impact. Weighted average exchangeable Operating Partnership units outstanding for the three months ended March 31, 2017 and 2016 were 154,170.
