Business Segments [Abstract] |
Measurement of Total Segment Gross Operating Margin | The following table presents our measurement of total segment gross operating margin for the years indicated. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.
|  | For the Year Ended December 31, |
|  | 2023 |  |  | 2022 |  |  | 2021 |
Operating income |  | $ | 6,929 |  |  | $ | 6,907 |  |  | $ | 6,103 |
Adjustments to reconcile operating income to total segment gross operating margin (addition or subtraction indicated by sign): |  |  |  |  |  |  |  |  |  |  |  |
Depreciation, amortization and accretion expense in operating costs and expenses (1) |  |  | 2,215 |  |  |  | 2,107 |  |  |  | 2,011 |
Asset impairment charges in operating costs and expenses |  |  | 30 |  |  |  | 53 |  |  |  | 233 |
Net losses (gains) attributable to asset sales and related matters in operating costs and expenses |  |  | (10 | ) |  |  | 1 |  |  |  | 5 |
General and administrative costs |  |  | 231 |  |  |  | 241 |  |  |  | 209 |
Non-refundable payments received from shippers attributable to make-up rights (2) |  |  | 52 |  |  |  | 144 |  |  |  | 85 |
Subsequent recognition of revenues attributable to make-up rights (3) |  |  | (71 | ) |  |  | (97 | ) |  |  | (138 | )
Total segment gross operating margin |  | $ | 9,376 |  |  | $ | 9,356 |  |  | $ | 8,508 |
(1) | Excludes amortization of major maintenance costs for reaction-based plants, which are a component of gross operating margin.
(2) | Since make-up rights entail a future performance obligation by the pipeline to the shipper, these receipts are recorded as deferred revenue for GAAP purposes; however, these receipts are included in gross operating margin in the period of receipt since they are nonrefundable to the shipper.
(3) | As deferred revenues attributable to make-up rights are subsequently recognized as revenue under GAAP, gross operating margin must be adjusted to remove such amounts to prevent duplication since the associated non-refundable payments were previously included in gross operating margin.
Information by Business Segments | Gross operating margin by segment is calculated by subtracting segment operating costs and expenses from segment revenues, with both segment totals reflecting the adjustments noted in the preceding table, as applicable, and before the elimination of intercompany transactions. The following table presents gross operating margin by segment for the years indicated:
