Basic weighted average shares outstanding for purposes of basic earnings per share are less than the shares outstanding due to 370,400 shares, 584,700 shares and 564,100 shares of restricted stock for 2012, 2011 and 2010, respectively, which are accounted for as part of diluted weighted average shares outstanding in diluted earnings per share. The number of equivalent shares that were not included in weighted average shares outstanding assuming dilution, because their effect would have been anti-dilutive, was 229,000, 176,000 and 9,000 at December 31, 2012, 2011 and 2010, respectively.
