Options to purchase 352,250 shares and 0 shares at September 30, 2019 and 2018, respectively, were not included in the computation of net income per diluted share for the three months ended September 30, 2019, because the exercise price was greater than the average market price of the common share, therefore, the effect would be antidilutive. Options to purchase 352,250 and 117,600 shares at September 30, 2019 and 2018, respectively, were not included in the computation of net income per diluted share for the nine months ended September 30, 2019 and 2018, because the exercise price was greater than the average market price of the common share, therefore, the effect would be antidilutive. As of September 30, 2019, no contingently issuable shares were estimated to be awarded under the 2019, 2018 and 2017 total shareholder return plans, as stock performance targets were not met and are therefore not included in the calculation because the effect would be antidilutive. As of September 30, 2018, 45,840 contingently issuable shares were estimated to be awarded under the 2018 and 2017 total shareholder return plans, as stock performance targets had been met to date and were included in the diluted calculation. Performance-based restricted stock compensation totaling 30,137 and 17,081 shares were estimated to be awarded as of September 30, 2019 and 2018, respectively, and are included in the diluted calculation.
