[1] The aggregate grant date fair value of phantom unit awards issued during 2024 was $233 million based on a grant date market price of the Partnership’s common units ranging from $26.25 to $28.05 per unit.  An estimated annual forfeiture rate of 2.0% was applied to these awards.

[2] Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued.
