Net Income Per Share

9 Months Ended

Sep. 30, 2023

Net income per basic share is computed by dividing net income by the weighted-average number of shares outstanding for the period. Net income per diluted share is computed by dividing net income by the weighted-average number of shares assuming dilution for stock options and restricted stock units. Dilutive shares reflect the potential additional shares that would be outstanding if the dilutive stock options outstanding were exercised and the unvested restricted stock units vested during the period. The computation of net income per share for the three and nine months ended September 30, 2023 and 2022 was as follows:

Options that were considered antidilutive were not included in the computation of diluted net income per share.
