EARNINGS PER UNIT</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Basic and diluted earnings per unit (including earnings per unit for LP Units and Class B Units) is calculated by dividing net income, after deducting the amount allocated to noncontrolling interests, by the weighted-average number of LP Units and Class B Units outstanding during the period. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Pursuant to the Merger Agreement, BGH’s unitholders received a total of approximately 20.0 million of Buckeye’s LP Units in the aggregate in exchange for all outstanding BGH common units and management units. As a result, the number of Buckeye’s LP Units outstanding increased from 51.6 million to 71.4 million on the date of the Merger. However, for historical reporting purposes, the impact of this change was accounted for as a reverse split of BGH’s units of 0.705 to 1.0, together with the addition of Buckeye’s existing LP Units. Therefore, since BGH was the surviving accounting entity, the weighted average number of units outstanding used for basic and diluted earnings per unit calculations are BGH’s historical weighted average common units outstanding adjusted for the reverse unit split and the addition of Buckeye’s existing LP Units. Amounts reflecting historical BGH unit and per unit amounts included in this report have been restated for the reverse unit split. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The following table is a reconciliation of the weighted average number of units used in the basic and diluted earnings per unit calculations for the periods indicated (in thousands, except per unit amounts): </div> <div align="center"> <table style="font-size: 10pt;
