Net Income per Limited Partner Unit [Abstract]  
Net Income Per Limited Partner Unit
Net Income Per Limited Partner Unit

Net income per unit applicable to the limited partners is computed using the two-class method, since we have more than one participating security as of March 31, 2018, common units and restricted units. Prior to the equity restructuring transaction described in Note 1, which was effective October 31, 2017, we had participating securities which included the aforementioned common units and restricted units as well as general partner units and IDRs. After the equity restructuring, the general partner interest was no longer entitled to any distributions, and none were made on the general partner interest after October 31, 2017.

To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings. Our dilutive securities, restricted units, are immaterial for all periods presented.

For purposes of applying the two-class method, including the allocation of cash distributions in excess of earnings, net income per limited partner unit is computed as follows:
