NET INCOME PER UNIT
NET INCOME PER UNIT

We have identified the general partner interest and incentive distribution rights (IDR) as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we have no potentially dilutive securities outstanding.

The following table details the calculation of earnings per unit:
