For the three months ended June 30, 2020 and 2021, there were 15,000 and no weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the nine months ended June 30, 2020 and 2021, there were 29,601 and 578 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive.
