For the fiscal years ended September 30, 2021, 2022, and 2023 there were 1,619, 71,976 and 10,963 weighted average shares of options outstanding and non-vested restricted stock outstanding, respectively, that were not included in the computation of diluted net income per share because the options’ exercise prices or non-vested restricted stock prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive.
