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,
	2018			2017			2016
Operating income	$	5,408.6		$	3,928.9		$	3,580.7
Adjustments to reconcile operating income to total gross operating margin:
Add depreciation, amortization and accretion expense in operating costs and expenses		1,687.0			1,531.3			1,456.7
Add asset impairment and related charges in operating costs and expenses		50.5			49.8			52.8
Subtract net gains attributable to asset sales in operating costs       and expenses		(28.7	)		(10.7	)		(2.5	)
Add general and administrative costs		208.3			181.1			160.1
Adjustments for make-up rights on certain new pipeline projects:
Add non-refundable payments received from shippers attributable to make-up rights (1)		21.5			24.1			17.5
Subtract the subsequent recognition of revenues attributable to make-up rights (2)		(56.2	)		(29.9	)		(34.6	)
Total segment gross operating margin	$	7,291.0		$	5,674.6		$	5,230.7
(1)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. (2)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:
