[1] The aggregate grant date fair value of phantom unit awards issued during 2023 was $229 million based on a grant date market price of the Partnership’s common units ranging from $25.80 to $25.95 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.
