Excluded from the dilutive securities shown above were options to purchase 212,968 and 177,414 shares of Common Stock during the three months ended March 31, 2013 and 2012, respectively. 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.
