Business Segments

Note 10.  Business Segments and Related Information

Segment Overview

Our operations are reported under four business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services and (iv) Petrochemical & Refined Products Services.  Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.  

Financial information regarding these segments is evaluated regularly by our co-chief operating decision makers in deciding how to allocate resources and in assessing our operating and financial performance.  The co-principal executive officers of our general partner have been identified as our co-chief operating decision makers.  While these two officers evaluate results in a number of different ways, the business segment structure is the primary basis for which the allocation of resources and financial results are assessed.

The following information summarizes the assets and operations of each business segment:

• Our NGL Pipelines & Services business segment includes our natural gas processing and related NGL marketing activities, NGL pipelines, NGL fractionation facilities, NGL and related product storage facilities, and NGL marine terminals.

• Our Crude Oil Pipelines & Services business segment includes our crude oil pipelines, crude oil storage and marine terminals, and related crude oil marketing activities.  

• Our Natural Gas Pipelines & Services business segment includes our natural gas pipeline systems that provide for the gathering, treating and transportation of natural gas.  This segment also includes our natural gas marketing activities.

• Our Petrochemical & Refined Products Services business segment includes our (i) propylene production facilities, which include propylene fractionation units and a PDH facility, and related pipelines and marketing activities, (ii) butane isomerization complex and related deisobutanizer operations, (iii) octane enhancement, iBDH and HPIB production facilities, (iv) refined products pipelines, terminals and related marketing activities, (v) ethylene export terminal and related operations; and (vi) marine transportation business.

Our plants, pipelines and other fixed assets are located in the U.S.

Segment Gross Operating Margin

We evaluate segment performance based on our financial measure of gross operating margin.  Gross operating margin is an important performance measure of the core profitability of our operations and forms the basis of our internal financial reporting.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results.  Gross operating margin is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests.  Our calculation of gross operating margin may or may not be comparable to similarly titled measures used by other companies.

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,
	2022			2021			2020
Operating income	$	6,907		$	6,103		$	5,035
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)		2,107			2,011			1,962
Asset impairment charges in operating costs and expenses		53			233			890
Net losses (gains) attributable to asset sales and related matters in operating costs and  expenses		1			5			(4	)
General and administrative costs		241			209			220
Non-refundable payments received from shippers attributable to make-up rights (2)		144			85			118
Subsequent recognition of revenues attributable to make-up rights (3)		(97	)		(138	)		(33	)
Total segment gross operating margin	$	9,356		$	8,508		$	8,188

(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.

The results of operations from our liquids pipelines are primarily dependent upon the volumes transported and the associated fees we charge for such transportation services.  Typically, pipeline transportation revenue is recognized when volumes are re-delivered to customers.  However, under certain pipeline transportation agreements, customers are required to ship a minimum volume over an agreed-upon period.  These arrangements may entail the shipper paying a transportation fee based on a minimum volume commitment, with a provision that allows the shipper to make-up any volume shortfalls over the agreed-upon period (referred to as shipper “make-up rights”).  Revenue pursuant to such agreements is initially deferred and subsequently recognized under GAAP at the earlier of when the deficiency volume is shipped, when the likelihood of the shipper’s ability to meet the minimum volume commitment becomes remote, or when the pipeline is otherwise released from its performance obligation.

However, management includes deferred transportation revenues relating to the “make-up rights” of committed shippers when reviewing the financial results of certain pipelines (Texas Express Pipeline, Front Range Pipeline, ATEX, Aegis Ethane Pipeline, and Seaway Pipeline).  From an internal (and segment) reporting standpoint, management considers the transportation fees paid by committed shippers on these pipelines, including any non-refundable revenues that may be deferred under GAAP related to make-up rights, to be important in assessing the financial performance of these pipeline assets.  Although the adjustments for make-up rights are included in segment gross operating margin, our consolidated revenues do not reflect any deferred revenues until the conditions for recognizing such revenues are met in accordance with GAAP.

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:

	For the Year Ended December 31,
	2022		2021		2020
Gross operating margin by segment:
NGL Pipelines & Services	$	5,142	$	4,316	$	4,182
Crude Oil Pipelines & Services		1,655		1,680		1,997
Natural Gas Pipelines & Services		1,042		1,155		927
Petrochemical & Refined Products Services		1,517		1,357		1,082
Total segment gross operating margin	$	9,356	$	8,508	$	8,188

Segment revenues include intersegment and intrasegment transactions, which are generally based on transactions made at market-based rates.  Our consolidated revenues reflect the elimination of intercompany transactions.

We include equity in income of unconsolidated affiliates in our measurement of segment gross operating margin and operating income.  Equity investments with industry partners are a significant component of our business strategy.  They are a means by which we conduct our operations to align our interests with those of customers and/or suppliers.  This method of operation enables us to achieve favorable economies of scale relative to the level of investment and business risk assumed.  Many of these businesses perform supporting or complementary roles to our other midstream business operations.

Our integrated midstream energy asset network (including the midstream energy assets owned by our unconsolidated affiliates) provides services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals.  In general, hydrocarbons may enter our asset system in a number of ways, such as through a natural gas gathering pipeline, natural gas processing facility, a crude oil pipeline or terminal, an NGL fractionator, an NGL storage facility or an NGL gathering or transportation pipeline.  The assets of many of our equity investees are included within our integrated midstream network.  For example, we use the Front Range Pipeline and Texas Express Pipeline to transport mixed NGLs to our Chambers County NGL fractionation and storage complex and the Seaway Pipeline to transport crude oil to our terminals in the Houston, Texas area.  Given the integral nature of these equity method investees to our operations, we believe the presentation of equity earnings from such investees as a component of gross operating margin and operating income is meaningful and appropriate.

Year ended December 31, 2020		20,786		12,485		9,402		8,619		1,808		53,100

Segment assets consist of property, plant and equipment, investments in unconsolidated affiliates, intangible assets and goodwill.  The carrying values of such amounts are assigned to each segment based on each asset’s or investment’s principal operations and contribution to the gross operating margin of that particular segment.  Since construction-in-progress (a component of property, plant and equipment) does not contribute to segment gross operating margin, such amounts are excluded from segment asset totals until the underlying assets are placed in service.  Intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate.  The remainder of our consolidated total assets, which consist primarily of working capital assets, are excluded from segment assets since these amounts are not attributable to one specific segment (e.g., cash).

Supplemental Revenue and Expense Information

The following table presents additional information regarding our consolidated revenues and costs and expenses for the years indicated:

	For the Year Ended December 31,
	2022		2021		2020
Consolidated revenues:
NGL Pipelines & Services	$	24,259	$	16,302	$	11,177
Crude Oil Pipelines & Services		18,561		10,902		6,689
Natural Gas Pipelines & Services		6,260		4,400		2,553
Petrochemical & Refined Products Services		9,106		9,203		6,781
Total consolidated revenues	$	58,186	$	40,807	$	27,200
Consolidated costs and expenses:
Operating costs and expenses:
Cost of sales	$	45,836	$	29,887	$	16,723
Other operating costs and expenses (1)		3,454		2,915		2,800
Depreciation, amortization and accretion		2,158		2,038		1,962
Impairment of goodwill		–		–		296
Impairment of assets other than goodwill		53		233		594
Net losses (gains) attributable to asset sales and related matters		1		5		(4	)
General and administrative costs		241		209		220
Total consolidated costs and expenses	$	51,743	$	35,287	$	22,591

(1) Represents the cost of operating our plants, pipelines and other fixed assets excluding: depreciation, amortization and accretion charges; asset impairment charges; and net losses (gains) attributable to asset sales and related matters.

Fluctuations in our product sales revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  In general, higher energy commodity prices result in an increase in our revenues attributable to product sales; however, these higher commodity prices would also be expected to increase the associated cost of sales as purchase costs are higher.  The same type of relationship would be true in the case of lower energy commodity sales prices and purchase costs.

Major Customer Information

Substantially all of our consolidated revenues are earned in the U.S. and derived from a wide customer base.  For the year ended December 31, 2022, Vitol Holding B.V. and its affiliates (collectively, “Vitol”) accounted for $5.92 billion, or 10.2%, of our consolidated revenues.  Vitol is a global energy and commodity trading company. Revenues earned from Vitol during 2022 are included within each of our four business segments.

No single customer accounted for 10% or more of our consolidated revenues during the years ended December 31, 2021 or 2020.
