  restricted stock units and stock options. 
  
  As of September 30, 2024, we had unrecognized stock-based compensation expense of $487 million under these grants 
  to purchase or receive an aggregate 4.9 million shares of our common stock. For awards probable of achievement, we estimate 
  the unrecognized stock-based compensation expense of $457 million will be recognized over a weighted-average period of 4.3 
  years. 
  
  For the three and nine months ended September 30, 2024 and 2023, stock-based compensation expense related to these
