[1] During the fourth quarter of 2021, the partnership reclassified $2,036 million of depreciation and amortization expenses, which were previously presented as a separate line item, to direct operating costs. Prior period amounts were also adjusted to reflect this change, which resulted in an increase to direct operating costs by $1,705 million and $1,214 million for years ended December 31, 2020 and 2019, respectively, with equal and offsetting decreases to depreciation and amortization expense. This reclassification had no impact on revenues, net income, or basic and diluted earnings per limited partner unit.
