(1)
Weighted average convertible limited partnership units of 2,228,404 and 2,233,088, which includes vested Series Z incentive units, for the three and nine months ended September 30, 2011, respectively, and weighted average convertible limited partnership units of 2,200,907 and 2,325,220 which includes vested Series Z incentive units, for the three and nine months ended September 30, 2010, respectively, were not included in the determination of diluted EPS because they were 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.

Stock options of 22,000 and 116,747 for the three months ended September 30, 2011 and 2010, respectively, and 29,500 and 133,432 for the nine months ended September 30, 2011 and 2010, respectively, were not included in the diluted earnings per share calculation because the exercise prices of the options were greater than the average market price of the common shares for the three and six months ended and, therefore, were anti-dilutive.

All shares of cumulative convertible preferred stock Series G have been excluded from diluted earnings per share for the three and nine months ended September 30, 2011 and 2010, as the effect was anti-dilutive.

 
(2)
Net income allocated to convertible limited partnership units, which includes vested Series Z units, aggregating $0.6 million and $0.5 million for the three months ended September 30, 2011 and 2010 respectively, and $2.2 million and $2.4 million for the nine months ended September 30, 2011 and 2010, respectively, have been excluded from income available to common stock holders for the calculation of net 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.
