(1)

Weighted average convertible limited partnership units of 2,239,057 and 2,230,354, which includes vested Series Z incentive units, for the three months ended June 30, 2012, and 2011, respectively, and 2,242,112 and 2,230,354 for the six months ended June 30, 2012 and 2011, respectively, were not included in the determination of diluted EPS because they were anti-dilutive. Income allocated to convertible limited partnership units, which includes vested Series Z units, aggregating $2.5 million and $1.0 million for the three months ended June 30, 2012 and 2011, respectively, and $4.1 million and $1.6 million for the six months ended June 30, 2012 and 2011, respectively, have been excluded from income available to common stock holders for the calculation of diluted income per common share since these units are excluded from the diluted weighted average common shares for the period as the effect was anti-dilutive. The Company has the ability to redeem DownREIT limited partnership units for cash and does not consider them to be potentially dilutive securities.
