| Schedule of Earnings Per Share, Basic and Diluted |
Net income per unit applicable to common limited partner units is computed by dividing the respective limited partners' interest in net income by the weighted-average number of common units outstanding for the period. Because the Partnership has more than one class of participating securities, it uses the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units and incentive distribution rights. Net income attributable to the Partnership is allocated to the unitholders in accordance with their respective ownership percentages in preparation of the consolidated statements of changes in equity. However, in the event distributions related to the incentive distribution rights are made, net income equal to the amount of those distributions would first be allocated to the general partner before the remaining net income would be allocated to the unitholders based on their respective ownership percentages. Basic and diluted net income per unit is the same because the Partnership does not have any potentially dilutive units outstanding for the periods presented. | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended June 30, 2026 | | | Limited Partners' Common Units | | Incentive Distribution Rights | | Total | | Net income attributable to the Partnership: | | | | | | | | Distribution | | $ | 16,615 | | | $ | — | | | $ | 16,615 | | Distribution in excess of net income | | (2,377) | | | — | | | (2,377) | | | Net income | | $ | 14,238 | | | $ | — | | | $ | 14,238 | | | Weighted average units outstanding: | | | | | | | | Basic and diluted | | 35,245,879 | | | | | 35,245,879 | | | Net income per limited partner unit: | | | | | | | | Basic and diluted | | $ | 0.40 | | | | | |
