[1] The aggregate grant date fair value of phantom unit awards issued during 2022 was $192 million based on a grant date market price of the Partnership’s common units ranging from $24.10 to $26.62 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.
