Options to purchase 123,292, 264,447 and 502,103 shares of Common Stock were outstanding during 2011, 2010 and 2009, 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 exceeds the weighted shares outstanding in the options, or if we have a net loss, as the effects are anti-dilutive.
