For the twelve months ended December 31, 2012, 2011 and 2010, stock-based awards, primarily stock options, which could result in the issuance of 1.0 million, 1.3 million and 1.3 million shares, respectively, were outstanding, but were not included in the computation of earnings per common share – diluted, because the effect of including such awards would have been antidilutive. In addition there is no adjustment to fully diluted shares related to the Convertible Senior Notes as the average market price was below the conversion price for the period.
