Earnings Per Share [Abstract] |
NET INCOME PER COMMON UNIT | NET INCOME PER COMMON UNIT Basic net income per common unit is determined pursuant to the two-class method. Under this method, all earnings are allocated to our limited partners and participating securities based on their respective rights to receive distributions earned during the period. Participating securities include our general partner interest and restricted units awarded under our long-term incentive plan. We compute basic net income per common unit by dividing net income attributable to common units by the weighted-average number of common units outstanding during the period. The following table details the calculation of net income per common unit:
