Earnings Per Share [Abstract]

Per common share amounts

Note 12. Per Common Share Amounts

The following table provides a reconciliation of the weighted average number of common shares used in the computation of basic and diluted EPS. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities and are included in our computation of basic and diluted EPS using the two-class method. Other potentially dilutive common shares, including contingently issuable common shares under our business management agreement with RMR, restricted shares, and the related impact on earnings, are considered when calculating diluted EPS (in thousands):

	Year Ended December 31,
	2014		2013		2012
Weighted average common shares for basic earnings per share		198,868		187,271		169,508
Effect of dilutive securities: restricted share awards		26		143		163
Weighted average common shares for diluted earnings per share		198,894		187,414		169,671

We had no anti-dilutive common share equivalents outstanding for the years ended December 31, 2014, 2013 and 2012.
