Business Segments [Abstract] |
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 chief operating decision makers in deciding how to allocate resources and in assessing operating and financial performance. The Chief Executive Officer and President of our general partner have been identified as our 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 current assets and operations of each business segment (mileage and other statistics are unaudited):
 | Our NGL Pipelines & Services business segment includes our natural gas processing plants and associated NGL marketing activities; approximately 19,600 miles of NGL pipelines; NGL and related product storage facilities; and 14 NGL fractionators. This segment also includes our NGL export docks and related operations.
 | Our Crude Oil Pipelines & Services business segment includes approximately 5,800 miles of crude oil pipelines, crude oil storage terminals located in Oklahoma and Texas, and associated crude oil marketing activities.
 | Our Natural Gas Pipelines & Services business segment includes approximately 19,700 miles of natural gas pipeline systems that provide for the gathering and transportation of natural gas in Colorado, Louisiana, New Mexico, Texas and Wyoming. This segment also includes our natural gas marketing activities.
 | Our Petrochemical & Refined Products Services business segment includes (i) propylene production facilities, which include our propylene fractionation units and recently completed PDH facility, approximately 800 miles of pipelines, and associated marketing operations; (ii) a butane isomerization complex and related deisobutanizer units; (iii) octane enhancement and high purity isobutylene production facilities; (iv) refined products pipelines aggregating approximately 4,100 miles, terminals and associated marketing activities; and (v) marine transportation.
Our plants, pipelines and other fixed assets are located in the U.S. Sale of Offshore Business In July 2015, we completed the sale of our Offshore Business, which comprised our Offshore Pipelines & Services business segment, to Genesis for approximately $1.53 billion in cash. Our Offshore Business served drilling and development regions, including deepwater production fields, in the northern Gulf of Mexico offshore Alabama, Louisiana, Mississippi and Texas and included approximately 2,350 miles of offshore natural gas and crude oil pipelines and six offshore hub platforms. We viewed our Offshore Business as an extension of our midstream energy services network. As such, the sale of these assets did not represent a strategic shift in our consolidated operations, and their sale did not have a major effect on our financial results. The sale of this non-strategic business allowed us to redeploy capital to other business opportunities that we believe will generate a higher rate of return for us in the future (e.g., our acquisition of EFS Midstream – see Note 12). 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. The following table presents our measurement of total segment gross operating margin for the periods presented. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.
|  | For the Year Ended December 31, |
|  | 2017 |  |  | 2016 |  |  | 2015 |
Income before income taxes |  | $ | 2,881.3 |  |  | $ | 2,576.4 |  |  | $ | 2,555.9 |
Add total other expense, net |  |  | 1,047.6 |  |  |  | 1,004.3 |  |  |  | 984.3 |
Operating income |  |  | 3,928.9 |  |  |  | 3,580.7 |  |  |  | 3,540.2 |
Adjustments to reconcile operating income to total gross operating margin: |  |  |  |  |  |  |  |  |  |  |  |
Add depreciation, amortization and accretion expense in operating costs and expenses |  |  | 1,531.3 |  |  |  | 1,456.7 |  |  |  | 1,428.2 |
Add asset impairment and related charges in operating costs and expenses |  |  | 49.8 |  |  |  | 52.8 |  |  |  | 162.6 |
Add net losses or subtract net gains attributable to asset sales in operating costs and expenses |  |  | (10.7 | ) |  |  | (2.5 | ) |  |  | 15.6 |
Add general and administrative costs |  |  | 181.1 |  |  |  | 160.1 |  |  |  | 192.6 |
Adjustments for make-up rights on certain new pipeline projects: |  |  |  |  |  |  |  |  |  |  |  |
Add non-refundable payments received from shippers attributable to make-up rights (1) |  |  | 24.1 |  |  |  | 17.5 |  |  |  | 53.6 |
Subtract the subsequent recognition of revenues attributable to make-up rights (2) |  |  | (29.9 | ) |  |  | (34.6 | ) |  |  | (60.7 | )
Total segment gross operating margin |  | $ | 5,674.6 |  |  | $ | 5,230.7 |  |  | $ | 5,332.1 |
(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. |
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, including that associated with make-up rights, is initially deferred and subsequently recognized under GAAP at the earlier of when the deficiency volume is shipped, when the shipper’s ability to meet the minimum volume commitment has expired (typically a one year contractual period), or when the pipeline is otherwise released from its transportation service performance obligation. However, management includes deferred transportation revenues relating to the “make-up rights” of committed shippers when reviewing the financial results of certain new pipeline projects (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 pipeline projects, 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 periods indicated:

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. Substantially all of our consolidated revenues are earned in the U.S. and derived from a wide customer base. 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 equity method investees) 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 processing plant, a natural gas gathering pipeline, a crude oil pipeline or terminal, an NGL fractionator, an NGL storage facility or an NGL gathering or transportation pipeline. Many of our equity investees are included within our integrated midstream asset network. For example, we use the Front Range Pipeline and Texas Express Pipeline to transport mixed NGLs to our Mont Belvieu complex for fractionation and storage and the Seaway Pipeline to transport crude oil to our terminals in the Houston, Texas area. Given the integral nature of our 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.

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 amounts (a component of property, plant and equipment) generally do 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). Other Revenue and Expense Information The following table presents supplemental information regarding our consolidated revenues and costs and expenses for the periods indicated:

(1) Represents the cost of operating our plants, pipelines and other fixed assets excluding: depreciation, amortization and accretion charges; asset impairment and related charges; and net losses (or gains) attributable to asset sales and insurance recoveries. |
Fluctuations in our product sales revenues and related cost of sales amounts are explained in part by changes in energy commodity prices. In general, lower energy commodity prices result in a decrease in our revenues attributable to product sales; however, these lower commodity prices also decrease the associated cost of sales as purchase costs decline. The same correlation would be true in the case of higher energy commodity sales prices and purchase costs. Major Customer Information Our largest non-affiliated customer for 2017 was Vitol Holding B.V. and its affiliates (collectively, “Vitol”), which accounted for $3.29 billion, or 11.2%, of our consolidated revenues for the year. Vitol is a global energy and commodity trading company. The following table presents our consolidated revenues from Vitol by business segment for the year ended December 31, 2017:
NGL Pipelines & Services |  | $ | 2,099.1 |
Crude Oil Pipelines & Services |  |  | 625.6 |
Natural Gas Pipelines & Services |  |  | 51.1 |
Petrochemical & Refined Products Services |  |  | 512.5 |
Total |  | $ | 3,288.3 |
Vitol was our largest non-affiliated customer for 2016, accounting for 9.9% of our consolidated revenues. Shell Oil Company and its affiliates was our largest non-affiliated customer for 2015, accounting for 7.4%, of our consolidated revenues.
