Options to purchase 233,655, 123,292 and 264,447 shares of Common Stock were outstanding during 2012, 2011 and 2010, respectively, but were not included in the computation of diluted earnings per share. These exclusions are made if the exercise prices of these options are greater than the average market price of our Common Stock for the period, if the number of shares we can repurchase under the treasury stock method exceeds the weighted shares outstanding in the options, or if we have a net loss, as the effects are anti-dilutive.
