The table above excludes from the calculations of diluted earnings per share weighted average convertible OP Units of 2,273,413 and 2,252,234, which include vested Series Z-1 Incentive Units, 2014 Long-Term Incentive Plan Units, and 2015 Long-Term Incentive Plan Units for the three months ended March 31, 2018 and 2017, respectively, because they were anti-dilutive. The related income allocated to these convertible OP Units aggregated $3.1 million and $6.1 million for the three months ended March 31, 2018 and 2017, respectively. Additionally, the table excludes all DownREIT limited partnership 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 364,068 and 225,895 for the three months ended March 31, 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 periods ended and, therefore, were anti-dilutive.
