For fiscal 2023, 2022 and 2021, no options were excluded from the calculation of dilutive potential common shares. The Convertible Notes had no impact on the calculation of dilutive potential common shares in fiscal 2023, as the price of our common stock did not exceed the conversion price. The Capped Call Transactions are excluded from the calculation of dilutive potential common shares as their effect is anti-dilutive.
