(1)Net income attributable to common limited partners' ownership interest is allocated to the phantom units on a pro-rata basis (weighted average phantom units outstanding as a percentage of the sum of the weighted average phantom units and common limited partner units outstanding).  For the three months ended March 31, 2013, net loss attributable to common limited partners' ownership interest is not allocated to approximately 1,055,000 phantom units, because the contractual terms of the phantom units as participating securities do not require the holders to share in the losses of the entity.
