NET INCOME PER COMMON SHARE [Abstract]  
NET INCOME PER COMMON SHARE
NOTE 3 ¾ NET INCOME PER COMMON SHARE
 
Basic net income per common share is computed by dividing net income, after deducting preferred share dividends and adjusting for the impact of unvested stock awards deemed to be participating securities, by the weighted average number of common shares outstanding, calculated excluding unvested stock awards.

Diluted net income per common share is computed by dividing net income available to common stockholders, after adding dividends on the Company’s Series A and B convertible preferred shares when such shares were dilutive, by the basic weighted average number of common shares and common share equivalents outstanding, giving effect to equity awards and these convertible preferred shares when such awards and shares were dilutive.  Prior to their redemption in June 2013, the Series A and B preferred shares were considered dilutive whenever basic net income per common share exceeded each Series’ dividend divided by the conversion rates applicable for that period.  Shares of the Company’s 7.50% Series E Cumulative Redeemable Preferred Stock first issued in May 2013 are contingently convertible into common shares only upon the occurrence of a change in control and are therefore not presently considered dilutive securities.  Unvested stock awards that are deemed participating securities are included in the calculation of diluted net income per common share, if dilutive, under either the two-class method or the treasury stock method, depending upon which method produces the more dilutive result.
