Vesting period, description |  |  |  | For the remaining half of the PBRSUs granted in the six months ended October 24, 2025, the number of shares used to calculate the settlement amount will depend upon the Company's billings result average over the three-year performance period. The billings result average is computed based on achievement against annual billings targets, with each target set at the beginning of the respective fiscal year, during the three-year performance period. Billings for purposes of measuring the performance of these PBRSUs means the total obtained by adding net revenues as reported on the Company's condensed consolidated statements of income to the amount reported as the change in deferred revenue and financed unearned services revenue on the condensed consolidated statements of cash flows for the applicable measurement period, excluding the impact of fluctuations in foreign currency exchange rates. |  |
