Earnings Per Share And Unit [Abstract]

12.	Earnings per Share and Unit

Parent Company Earnings per Share

The following summarizes the calculation of basic and diluted earnings per share:

	Three months ended September 30,				Nine months ended September 30,
(in thousands, except per share data)	2019		2018		2019		2018
Numerator:
Income from operations attributable to common stockholders - basic	$	56,965	$	69,722	$	199,139	$	170,222
Income from operations attributable to common stockholders - diluted	$	56,965		69,722	$	199,139		170,222
Denominator:
Weighted average common shares outstanding for basic EPS		167,559		169,438		167,512		169,847
Weighted average common shares outstanding for diluted EPS ⁽¹⁾		167,944		169,839		167,834		170,166
Income per common share – basic	$	0.34		0.41	$	1.19		1.00
Income per common share – diluted	$	0.34		0.41	$	1.19		1.00

⁽¹⁾ Includes the dilutive impact of unvested restricted stock 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 be anti-dilutive. Weighted average exchangeable Operating Partnership units outstanding for the three and nine months ended September 30, 2019 was 405,934 and 368,854, respectively. Weighted average exchangeable Operating Partnership units outstanding for both the three and nine months ended September 30, 2018 was 349,902.

The 1.9 million shares issuable under the forward sale agreements are excluded for the three and nine months ended September 30, 2019 because they would be anti-dilutive.
