Weighted average recognition period of unrecognized compensation expense for shares expected to vest		2 years 11 months 15 days

[1] The unrecognized compensation expense calculated under the fair value method for shares expected to vest as of May 31, 2024 was approximately $76 million and is expected to be recognized over a weighted-average period of 2.96 years. Approximately 16 million shares outstanding as of May 31, 2024 were not expected to vest.

[2] The aggregate intrinsic value was calculated based on the gross difference between our closing stock price on the last trading day of fiscal 2024 of $117.19 and the exercise prices for all “in-the-money” options outstanding, excluding tax effects.
