Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating securities is calculated according to dividends declared and participation rights in undistributed earnings. For 2013, 2012 and 2011, we had 0.3 million weighted average unvested shares outstanding, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares; the portion of earnings allocated to the unvested shares is reflected as “earnings allocated to unvested shares” in the reconciliation below.

In the dilutive EPS calculation, dilutive stock options were calculated using the treasury stock method consistent with prior periods. There were no anti-dilutive stock options in 2013 or 2012. Approximately 0.1 million stock options were excluded in 2011 as they were anti-dilutive. The conversions of downREIT operating partnership units and 5.417% Series 1 Cumulative Convertible Preferred Shares are anti-dilutive for all periods presented and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.
