Income per limited partner unit is computed in accordance with FASB ASC 260-10-05 Earnings Per Share, Master Limited Partnerships (EITF 03-06), by dividing the limited partners’ interest in net income by the weighted average number of limited partner units outstanding. The pro forma nature of the allocation required by this standard provides that in any accounting period where the Company’s aggregate net income exceeds its aggregate distribution for such period, the Company is required to present net income per limited partner unit as if all of the earnings for the periods were distributed, regardless of whether those earnings would actually be distributed during a particular period from an economic or practical perspective. This allocation does not impact the Company’s overall net income or other financial results. However, for periods in which the Company’s aggregate net income exceeds its aggregate distributions for such period, it will have the impact of reducing the earnings per limited partner unit, as the calculation according to this standard result in a theoretical increased allocation of undistributed earnings to the General Partner. In accounting periods where aggregate net income does not exceed aggregate distributions for such period, this standard does not have any impact on the Company’s net income per limited partner unit calculation. A separate and independent calculation for each quarter and year-to-date period is performed, in which the Company’s contractual participation rights are taken into account.
