Business Segments [Abstract] |  |  |  |  |
Number of reportable segments | Segment |  |  |  | 4 |
Gross Operating Margin |  |  |  |  |
Operating income |  | $ 1,579 | $ 1,764 | $ 3,313 | $ 3,430
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] | 545 | 531 | 1,078 | 1,045
Asset impairment charges in operating costs and expenses |  | 3 | 5 | 16 | 19
Net losses (gains) attributable to asset sales and related matters in operating costs and expenses |  | (2) | 0 | (4) | 2
General and administrative costs |  | 56 | 62 | 113 | 124
Non-refundable payments received from shippers attributable to make-up rights | [2] | (3) | 39 | 24 | 73
Subsequent recognition of revenues attributable to make-up rights | [3] | (25) | (17) | (45) | (45)
Total segment gross operating margin |  | $ 2,153 | $ 2,384 | $ 4,495 | $ 4,648
[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.
