(1) Earnings per share amounts are calculated based on unrounded numbers and therefore may not recalculate using the rounded numbers provided.

We adopted ASU 2020-06 in the first quarter of Fiscal 2023, which required us to prospectively utilize the if-converted method to calculate the dilutive impact of all convertible notes. Prior to adoption, we utilized the treasury stock method for calculating the dilutive impact of convertible notes.

Under the if-converted method, the 2025 Convertible Notes are assumed to be converted into common stock at the beginning of the reporting period, as the 2025 Convertible Notes will be convertible into cash, shares of our common stock or a combination thereof, at our election. If dilutive, the resulting shares are included in the denominator of the calculation and interest charges, net of any income tax effects are added back to the numerator of the calculation. For the 2030 Convertible Notes, we are required to settle the principal amount in cash and any conversion premium in excess of the principal amount in cash, shares of common stock, or a combination of cash and shares of common stock, at our election. As such, the 2030 Convertible Notes only have an impact on diluted earnings per share when the average share price of our common stock exceeds the conversion price.

For all periods presented, the dilutive effect of stock compensation awards, if any, was determined using the treasury stock method. Under the treasury stock method, shares associated with certain anti-dilutive securities have been excluded from the diluted weighted average shares outstanding calculation because the exercise of those options would lead to a net reduction in common shares outstanding or anti-dilution.
