Partners' Capital Notes [Abstract]

Net Income Per Limited Partner Unit

Net Income Per Limited Partner UnitNet income per unit applicable to common limited partner units is computed by dividing the respective limited partners’ interest in net income attributable to the Partnership for the period by the weighted average number of common units outstanding for the period. Because we have more than one class of participating securities, we use the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units, general partner units and IDR’s. Basic and diluted net income per unit are the same because we do not have any potentially dilutive units outstanding for the periods presented.

Net income earned by the Partnership is allocated between the limited partners and the general partner (including IDR’s) in accordance with our partnership agreement. Earnings are allocated based on actual cash distributions declared to our unitholders, including those attributable to IDR’s. To the extent net income attributable to the Partnership exceeds or is less than cash distributions, this difference is allocated based on the unitholders’ respective ownership percentages.

The following tables show the allocation of net income attributable to the Partnership to arrive at net income per limited partner unit:
