Excluded from the dilutive securities shown above were options to purchase 408,979 and 237,405 shares of Common Stock during the three months ended June 30, 2016 and 2015, respectively. Excluded from the dilutive securities shown above were options to purchase 405,123 and 215,767 shares of Common Stock during the six months ended June 30, 2016 and 2015, respectively. These exclusions were made if the exercise prices of the 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 average shares outstanding in the options or if we have a net loss, as these effects are anti-dilutive.
