Net Income Per Common Share and Net Income Per Common Unit

Essex Property Trust, Inc.

Basic and diluted income per share is calculated as follows for the years ended December 31 ($ in thousands, except share and per share amounts):



	2019					2018					2017
	Income		Weighted- average Common Shares	Per Common Share Amount		Income		Weighted- average Common Shares	Per Common Share Amount		Income		Weighted- average Common Shares	Per Common Share Amount
Basic:
Net income available to common stockholders	$	439,286	65,840,422	$	6.67	$	390,153	66,041,058	$	5.91	$	433,059	65,829,155	$	6.58
Effect of Dilutive Securities
Stock options	—		99,033			—		44,031			—		69,100
Diluted:
Net income available to common stockholders	$	439,286	65,939,455	$	6.66	$	390,153	66,085,089	$	5.90	$	433,059	65,898,255	$	6.57

The table above excludes from the calculations of diluted earnings per share weighted average convertible OP Units of 2,300,478, 2,274,941, and 2,252,575, which include vested Series Z-1 Incentive Units, 2014 Long-Term Incentive Plan Units, and 2015 Long-Term Incentive Plan Units, for the years ended December 31, 2019, 2018 and 2017, respectively, because they were anti-dilutive. The related income allocated to these convertible OP Units aggregated $15.3 million, $13.5 million, and $14.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. Additionally, the table excludes all DownREIT units for which the Operating Partnership has the ability and intention to redeem the units for cash and does not consider them to be common stock equivalents.

Stock options of 115,066, 160,039, and 154,793, for the years ended December 31, 2019, 2018, and 2017, respectively, were excluded from the calculation of diluted earnings per share because the assumed proceeds per share of such options plus the

average unearned compensation were greater than the average market price of the common stock for the years ended and, therefore, were anti-dilutive.
