Earnings Per Common Share
Earnings per common share are based on the weighted average number of common shares outstanding during each year. Codification Topic “Earnings Per Share” (“FASB ASC 260”) defines the calculation of basic and fully diluted earnings per share. Basic and fully diluted earnings per share are based on the weighted average shares outstanding during each year and basic earnings per share exclude any dilutive effects of options, unvested restricted shares and convertible securities. The conversion of OP Units has been excluded from the basic earnings per share calculation. The conversion of an OP Unit for a share of common stock has no material effect on earnings per common share on a fully diluted basis.
 The following table sets forth the computation of basic and diluted earnings per common share for the years ended December 31, 2012, 2011 and 2010 (amounts in thousands):
