​ Net income per share is calculated pursuant to ASC Topic 260, “Earnings per Share” (“ASC Topic 260”). Basic earnings per share (“EPS”) excludes potentially dilutive securities and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed assuming the conversion or exercise of all dilutive securities such as employee stock options and restricted stock units (“RSUs”). ​ The number of incremental shares from the assumed exercise of stock options and RSUs is calculated by using the treasury stock method. As of September 30, 2024, 2023 and 2022, there were 361,613, 224,374 and 57,584 options to purchase common stock outstanding, respectively. As of September 30, 2024, 2023 and 2022, there were 242,080, 101,968 and 32,897 shares subject to vesting of restricted stock units outstanding, respectively. The average outstanding diluted shares calculation excludes options with an exercise price that exceeds the average market price of shares during the period. For fiscal years 2024 and 2023, 362,000 options and 203,000 options to purchase common stock were excluded from the computation of diluted earnings per share because the effect would be anti-dilutive. For fiscal year 2022, 0 shares were excluded from the calculation of earnings per share as their effect would be anti-dilutive.
