[1] The aggregate grant date fair value of phantom unit awards issued during 2020 was $190.4 million based on a grant date market price of EPD common units ranging from $17.24 to $25.76 per unit.  An estimated annual forfeiture rate of 2.4% 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.
