Share equivalents attributable to outstanding stock options, RSUs, PSUs and employee share purchase plans ("ESPP") totaling 2.0 million, 2.0 million, and 0.1 million shares during fiscal years 2023, 2022 and 2021, respectively, were excluded from the calculation of diluted net income per share because their effect would have been anti-dilutive. For fiscal years 2023 and 2022, a small number of performance-based awards were not included in the dilutive net income per share calculation because all necessary conditions had not been satisfied by the end of the respective period, and those shares were not issuable if the end of the reporting period were the end of the performance contingency period.
