Net Income Per Unit
NET INCOME PER UNIT

We use the two-class method when calculating the net income per unit applicable to limited partners, because we have more than one participating security. Our participating securities consist of common units, subordinated units, general partner units and IDRs. Net income earned by the Partnership is allocated between the limited (both common and subordinated) and general partners in accordance with our partnership agreement. We base our calculation of net income per unit on the weighted average number of common and subordinated limited partner units outstanding during the period. Diluted net income per unit includes the effects of potentially dilutive units on our common units, which consist of unvested service and performance phantom units. Basic and diluted net income per unit applicable to subordinated limited partners are the same, as there are no potentially dilutive subordinated units outstanding. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement. The calculation of net income per unit is as follows (in thousands, except unit and per unit amounts):

____________ 
(a)
General partner’s distributions (including IDRs) consist of an approximate 2% general partner interest and IDRs, which entitle the general partner to receive increasing percentages, up to 50%, of quarterly distributions in excess of $0.388125 per unit per quarter. See Note K of our Annual Report on Form 10-K for the year ended December 31, 2013 for further discussion related to IDRs.
(b)
We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. Therefore, as a result of the public offering of common units in January 2013, net income per common and subordinated limited partner units will not agree for the three months ended March 31, 2013.
