Net Income per Unit Net Income per Unit
Basic net income per unit attributable to limited partners is computed by dividing limited partners' interest in net income by the weighted-average number of outstanding common units. Diluted net income per unit attributable to common limited partners includes the effects of potentially dilutive units on our common units. For the years ended December 31, 2023, 2022 and 2021, potentially dilutive units outstanding consist of unvested phantom units.
The calculation of net income per unit is as follows (in thousands, except unit and per unit amounts):
