[1] Includes only those options that were in-the-money as of May 27, 2023. Stock options for which the exercise price exceeded the market price have been omitted. Fluctuations in the intrinsic value of both outstanding and exercisable options may result from changes in underlying stock price and timing and volume of option grants, exercises and forfeitures.
