BUSINESSOverviewWe (Energy Transfer Partners, L.P., a Delaware limited partnership, “ETP” or the “Partnership”) are one of the largest publicly traded master limitedpartnerships in the United States in terms of equity market capitalization (approximately $23.31 billion as of January 31, 2018). We are managed by ourgeneral partner, Energy Transfer Partners GP, L.P. (our “General Partner” or “ETP GP”), and ETP GP is managed by its general partner, Energy TransferPartners, L.L.C. (“ETP LLC”), which is owned by Energy Transfer Equity, L.P., another publicly traded master limited partnership (“ETE”). The primaryactivities in which we are engaged, all of which are in the United States, and the operating subsidiaries (collectively referred to as the “OperatingCompanies”) through which we conduct those activities are as follows:•Natural gas operations, including the following:•natural gas midstream and intrastate transportation and storage; and•interstate natural gas transportation and storage.•Crude oil, NGLs and refined product transportation, terminalling services and acquisition and marketing activities, as well as NGL storage andfractionation services.The following chart summarizes our organizational structure as of February 7, 2018. For simplicity, certain immaterial entities and ownership interest havenot been depicted.1 Table of ContentsUnless the context requires otherwise, the Partnership, the Operating Companies, and their subsidiaries are collectively referred to in this report as “we,” “us,”“ETP,” “Energy Transfer” or “the Partnership.”Significant Achievements in 2017 and BeyondStrategic TransactionsOur significant strategic transactions in 2017 and beyond included the following, as discussed in more detail herein:•In February 2017, Bakken Holdings Company LLC, an entity in which ETP indirectly owns a 100% membership interest, sold a 49% interest in itswholly-owned subsidiary, Bakken Pipeline Investments LLC, to MarEn Bakken Company LLC, an entity jointly owned by MPLX LP and EnbridgeEnergy Partners, L.P., for $2.00 billion in cash. Bakken Pipeline Investments LLC indirectly owns a 75% interest in each of Dakota Access and ETCO.The remaining 25% of each of Dakota Access and ETCO is owned by wholly-owned subsidiaries of Phillips 66. As discussed below, in July 2017, thePartnership contributed a portion of its ownership interest in Dakota Access and ETCO to PEP. ETP continues to consolidate Dakota Access and ETCOsubsequent to this transaction.•In February 2017, Sunoco Logistics formed PEP, a strategic joint venture with ExxonMobil. Sunoco Logistics contributed its Permian Express 1,Permian Express 2, Permian Longview and Louisiana Access pipelines. ExxonMobil contributed its Longview to Louisiana and Pegasus pipelines,Hawkins gathering system, an idle pipeline in southern Oklahoma, and its Patoka, Illinois terminal. Assets contributed to PEP by ExxonMobil werereflected at fair value on the Partnership’s consolidated balance sheet at the date of the contribution, including $547 million of intangible assets and$435 million of property, plant and equipment.•In April 2017, Energy Transfer Partners, L.P. and Sunoco Logistics completed a merger transaction (the “Sunoco Logistics Merger”) in which SunocoLogistics acquired Energy Transfer Partners, L.P. in a unit-for-unit transaction, with the Energy Transfer Partners, L.P. unitholders receiving 1.5 commonunits of Sunoco Logistics for each Energy Transfer Partners, L.P. common unit they owned. In connection with the merger, Sunoco Logistics wasrenamed Energy Transfer Partners, L.P. and Sunoco Logistics’ general partner was merged with and into ETP GP, with ETP GP surviving as an indirectwholly-owned subsidiary of ETE.•In July 2017, ETP contributed an approximate 15% ownership interest in Dakota Access and ETCO to PEP, which resulted in an increase in ETP’sownership interest in PEP to approximately 88%. ETP maintains a controlling financial and voting interest in PEP and is the operator of all of the assets.As such, PEP is reflected as a consolidated subsidiary of the Partnership. ExxonMobil’s interest in PEP is reflected as noncontrolling interest in theconsolidated balance sheets. ExxonMobil’s contribution resulted in an increase of $988 million in noncontrolling interest, which is reflected in “Capitalcontributions from noncontrolling interest” in the consolidated statement of equity.•In October 2017, ETP completed the previously announced contribution transaction with a fund managed by Blackstone Energy Partners andBlackstone Capital Partners, pursuant to which ETP exchanged a 49.9% interest in the holding company that owns 65% of the Rover pipeline (“RoverHoldco”). As a result, Rover Holdco is now owned 50.1% by ETP and 49.9% by Blackstone. Upon closing, Blackstone contributed funds to reimburseETP for its pro rata share of the Rover construction costs incurred by ETP through the closing date, along with the payment of additional amountssubject to certain adjustments.•In January 2018, ETP entered into a contribution agreement (“CDM Contribution Agreement”) with ETP GP, ETC Compression, LLC, USAC and ETE,pursuant to which ETP will contribute to USAC 100% of the membership interests of CDM and CDM E&T for aggregate consideration of $1.7 billion,consisting of USAC common units, new USAC Class B units and cash. The Class B units will be substantially similar to USAC common units, except theClass B units will not receive distributions paid with respect to USAC common units prior to the one year anniversary of the closing date of the CDMContribution Agreement. Each Class B Unit will convert into one USAC common unit on such one year anniversary. In connection with the foregoing,ETP entered into a purchase agreement with ETE, ETP LLC, USAC Holdings and, for certain limited purposes, R/C IV USACP Holdings, L.P., pursuant towhich ETE and ETP LLC will acquire from USAC Holdings (i) all of the outstanding interests in the general partner of USAC and (ii) 12,466,912 USACcommon units for $250 million in cash. The transactions are expected to close in the first half of 2018, subject to customary closing conditions.Significant Organic Growth ProjectsOur significant announced organic growth projects in 2017 included the following, as discussed in more detail herein:•In June 2017, ETP announced that the Dakota Access Pipeline and the Energy Transfer Crude Oil Pipeline (collectively, the “Bakken Pipeline”) wereplaced in commercial service.•ETP announced that Phase 1A and Phase 1B of the Rover pipeline were placed in service in August 2017 and December 2017, respectively.2 Table of ContentsSegment OverviewSee Note 15 to our consolidated financial statements in “Item 8. Financial Statements and Supplementary Data” for additional financial information aboutour segments.Intrastate Transportation and Storage SegmentNatural gas transportation pipelines receive natural gas from other mainline transportation pipelines, storage facilities and gathering systems and deliver thenatural gas to industrial end-users, storage facilities, utilities and other pipelines. Through our intrastate transportation and storage segment, we own andoperate approximately 7,900 miles of natural gas transportation pipelines with approximately 15.2 Bcf/d of transportation capacity and three natural gasstorage facilities located in the state of Texas. We also own a 49.99% general partner interest in RIGS, a 450-mile intrastate pipeline that delivers natural gasfrom northwest Louisiana to downstream pipelines and markets. We own a 16% membership interest in the Trans-Pecos and Comanche Trail pipelines, a 338-mile intrastate pipeline system that delivers natural gas from the Waha Hub near Midland, Texas to the United States/Mexico border.Through ETC OLP, we own the largest intrastate pipeline system in the United States with interconnects to Texas markets and to major consumption areasthroughout the United States. Our intrastate transportation and storage segment focuses on the transportation of natural gas to major markets from variousprolific natural gas producing areas through connections with other pipeline systems as well as through our Oasis pipeline, our East Texas pipeline, ournatural gas pipeline and storage assets that are referred to as the ET Fuel System, and our HPL System, which are described below.Our intrastate transportation and storage segment’s results are determined primarily by the amount of capacity our customers reserve as well as the actualvolume of natural gas that flows through the transportation pipelines. Under transportation contracts, our customers are charged (i) a demand fee, which is afixed fee for the reservation of an agreed amount of capacity on the transportation pipeline for a specified period of time and which obligates the customer topay even if the customer does not transport natural gas on the respective pipeline, (ii) a transportation fee, which is based on the actual throughput of naturalgas by the customer, (iii) fuel retention based on a percentage of gas transported on the pipeline, or (iv) a combination of the three, generally payablemonthly.We also generate revenues and margin from the sale of natural gas to electric utilities, independent power plants, local distribution companies, industrial end-users and marketing companies on our HPL System. Generally, we purchase natural gas from either the market (including purchases from our marketingoperations) or from producers at the wellhead. To the extent the natural gas comes from producers, it is primarily purchased at a discount to a specified marketprice and typically resold to customers based on an index price. In addition, our intrastate transportation and storage segment generates revenues from feescharged for storing customers’ working natural gas in our storage facilities and from managing natural gas for our own account.Interstate Transportation and Storage SegmentNatural gas transportation pipelines receive natural gas from other mainline transportation pipelines, storage facilities and gathering systems and deliver thenatural gas to industrial end-users, storage facilities, utilities and other pipelines. Through our interstate transportation and storage segment, we directly ownand operate approximately 11,800 miles of interstate natural gas pipelines with approximately 10.3 Bcf/d of transportation capacity and have a 50% interestin the joint venture that owns the 185-mile Fayetteville Express pipeline and the 500-mile Midcontinent Express pipeline. ETP also owns a 50% interest inCitrus, which owns 100% of FGT, an approximately 5,360-mile pipeline system that extends from South Texas through the Gulf Coast to south Florida. ETPoperates the FEP and FGT joint ventures.Our interstate transportation and storage segment includes Panhandle, which owns and operates a large natural gas open-access interstate pipelinenetwork. The pipeline network, consisting of the Panhandle, Trunkline and Sea Robin transmission systems, serves customers in the Midwest, Gulf Coast andMidcontinent United States with a comprehensive array of transportation and storage services. In connection with its natural gas pipeline transmission andstorage systems, Panhandle has five natural gas storage fields located in Illinois, Kansas, Louisiana, Michigan and Oklahoma. Southwest Gas operates four ofthese fields and Trunkline operates one.The Rover Pipeline is a new 713-mile natural gas pipeline designed to transport 3.25 Bcf/d of domestically produced natural gas from the Marcellus andUtica Shale production areas to markets across the United States as well as into the Union Gas Dawn Storage Hub in Ontario, Canada, for redistribution backinto the United States or into the Canadian market. Currently under construction, portions of the pipeline are in service transporting gas from processingplants in Eastern Ohio for delivery to other pipeline interconnects in Eastern Ohio as well as the Midwest Hub near Defiance, Ohio, where the gas will bedelivered for distribution to markets across the United States. The Rover Pipeline Phase 1A and 1B are in service with a capacity of approximately 1.7 Bcf/d.3 Table of ContentsWe also own a 50% interest in the MEP pipeline system, which is operated by KMI, and has the capability to transport up to 1.8 Bcf/d of natural gas.Gulf States is a small interstate pipeline that uses cost-based rates and terms and conditions of service for shippers wishing to secure capacity for interstatetransportation service. Rates charged are largely governed by long-term negotiated rate agreements.The results from our interstate transportation and storage segment are primarily derived from the fees we earn from natural gas transportation and storageservices.Midstream SegmentThe midstream natural gas industry is the link between the exploration and production of natural gas and the delivery of its components to end-use markets.The midstream industry consists of natural gas gathering, compression, treating, processing, storage, and transportation, and is generally characterized byregional competition based on the proximity of gathering systems and processing plants to natural gas producing wells and the proximity of storage facilitiesto production areas and end-use markets.The natural gas gathering process begins with the drilling of wells into gas-bearing rock formations. Once a well has been completed, the well is connected toa gathering system. Gathering systems generally consist of a network of small diameter pipelines and, if necessary, compression systems, that collects naturalgas from points near producing wells and transports it to larger pipelines for further transportation.Gathering systems are operated at design pressures that will maximize the total throughput from all connected wells. Specifically, lower pressure gatheringsystems allow wells, which produce at progressively lower field pressures as they age, to remain connected to gathering systems and to continue to producefor longer periods of time. As the pressure of a well declines, it becomes increasingly difficult to deliver the remaining production in the ground against ahigher pressure that exists in the connecting gathering system. Field compression is typically used to lower the pressure of a gathering system. If fieldcompression is not installed, then the remaining production in the ground will not be produced because it cannot overcome the higher gathering systempressure. In contrast, if field compression is installed, then a well can continue delivering production that otherwise might not be produced.Natural gas has a varied composition depending on the field, the formation and the reservoir from which it is produced. Natural gas from certain formations ishigher in carbon dioxide, hydrogen sulfide or certain other contaminants. Treating plants remove carbon dioxide and hydrogen sulfide from natural gas toensure that it meets pipeline quality specifications.Some natural gas produced by a well does not meet the pipeline quality specifications established by downstream pipelines or is not suitable for commercialuse and must be processed to remove the mixed NGL stream. In addition, some natural gas produced by a well, while not required to be processed, can beprocessed to take advantage of favorable margins for NGLs extracted from the gas stream. Natural gas processing involves the separation of natural gas intopipeline quality natural gas, or residue gas, and a mixed NGL stream.Through our midstream segment, we own and operate natural gas and NGL gathering pipelines, natural gas processing plants, natural gas treating facilitiesand natural gas conditioning facilities with an aggregate processing, treating and conditioning capacity of approximately 12.3 Bcf/d. Our midstream segmentfocuses on the gathering, compression, treating, blending, and processing, and our operations are currently concentrated in major producing basins andshales, including the Austin Chalk trend and Eagle Ford Shale in South and Southeast Texas, the Permian Basin in West Texas and New Mexico, the BarnettShale and Woodford Shale in North Texas, the Bossier Sands in East Texas, the Marcellus Shale in West Virginia and Pennsylvania, the Haynesville Shale inEast Texas and Louisiana, and the Cotton Valley Shale in Louisiana. Many of our midstream assets are integrated with our intrastate transportation andstorage assets.Our midstream segment also includes a 60% interest in ELG, which operates natural gas gathering, oil pipeline, and oil stabilization facilities in South Texas,a 33.33% membership interest in Ranch Westex JV LLC, which processes natural gas delivered from the NGLs-rich shale formations in West Texas, a 75%membership interest in ORS, which operates a natural gas gathering system in the Utica shale in Ohio, and a 50% interest in Mi Vida JV, which operates acryogenic processing plant and related facilities in West Texas, a 51% membership interest in Aqua – PVR, which transports and supplies fresh water tonatural gas producers in the Marcellus shale in Pennsylvania, and a 50% interest in Sweeny Gathering LP, which operates a natural gas gathering facility inSouth Texas.Our midstream segment results are derived primarily from margins we earn for natural gas volumes that are gathered, transported, purchased and sold throughour pipeline systems and the natural gas and NGL volumes processed at our processing and treating facilities.4 Table of ContentsNGL and Refined Products Transportation and Services SegmentOur NGL operations transport, store and execute acquisition and marketing activities utilizing a complementary network of pipelines, storage and blendingfacilities, and strategic off-take locations that provide access to multiple NGL markets.Liquids transportation pipelines transport mixed NGLs and other hydrocarbons from natural gas processing facilities to fractionation plants and storagefacilities. NGL storage facilities are used for the storage of mixed NGLs, NGL products and petrochemical products owned by third parties in storage tanksand underground wells, which allow for the injection and withdrawal of such products at various times of the year to meet demand cycles. NGL fractionatorsseparate mixed NGL streams into purity products, such as ethane, propane, normal butane, isobutane and natural gasoline.Our NGL and refined products transportation and services segment includes approximately 4,300 miles of NGL pipelines, five NGL and propanefractionation facilities with an aggregate capacity of 545 MBbls/d and NGL storage facilities with aggregate working storage capacity of approximately 53million Bbls. Four of our NGL and propane fractionation facilities and 50 million Bbls of our NGL storage capacity are located at Mont Belvieu, Texas, oneNGL fractionation facility is located in Geismar, Louisiana, and the segment has 3 million Bbls of salt dome storage capacity near Hattiesburg, Mississippi.We are currently constructing a fifth and sixth fractionator in Mont Belvieu, Texas, which are expected to be operational in the third quarter of 2018 and thesecond quarter of 2019, respectively. The NGL pipelines primarily transport NGLs from the Permian and Delaware basins and the Barnett and Eagle FordShales to Mont Belvieu.Terminalling services are facilitated by approximately 7 million Bbls of NGLs storage capacity, including approximately 1 million Bbls of storage at ourNederland, Texas terminal facility, 1 million Bbls of storage at our Inkster, Michigan terminal facility and 5 million Bbls at our Marcus Hook, Pennsylvaniaterminal facility (the “Marcus Hook Industrial Complex”). These operations also support our NGLs blending activities, including the use of our patentedbutane blending technology.Liquids transportation revenue is principally generated from fees charged to customers under dedicated contracts or take-or-pay contracts. Under a dedicatedcontract, the customer agrees to deliver the total output from particular processing plants that are connected to the NGL pipeline. Take-or-pay contracts haveminimum throughput commitments requiring the customer to pay regardless of whether a fixed volume is transported. Transportation fees are market-based,negotiated with customers and competitive with regional regulated pipelines.NGL fractionation revenue is principally generated from fees charged to customers under take-or-pay contracts. Take-or-pay contracts have minimumpayment obligations for throughput commitments requiring the customer to pay regardless of whether a fixed volume is fractionated from raw make intopurity NGL products. Fractionation fees are market-based, negotiated with customers and competitive with other fractionators along the Gulf Coast.NGL storage revenues are derived from base storage fees and throughput fees. Base storage fees are firm take-or-pay contracts on the volume of capacityreserved, regardless of the capacity actually used. Throughput fees are charged for providing ancillary services, including receipt and delivery and custodytransfer fees.This segment also includes revenues earned from the marketing of NGLs and processing and fractionating refinery off-gas. Marketing of NGLs primarilygenerates margin from selling ratable NGLs to end users and from optimizing storage assets. Processing and fractionation of refinery off-gas margin isgenerated from a percentage-of-proceeds of O-grade product sales and income sharing contracts, which are subject to market pricing of olefins and NGLs.Our refined products operations provide transportation and terminalling services through the use of approximately 2,200 miles of refined products pipelinesand approximately 40 active refined products marketing terminals. Our marketing terminals are located primarily in the northeast, midwest and southwestUnited States, with approximately 8 million Bbls of refined products storage capacity. Our refined products operations include our Eagle Point facility inNew Jersey, which has approximately 6 million Bbls of refined products storage capacity. We also include our equity ownership interests in four refinedproducts pipeline companies. The operations also perform terminalling activities at our Marcus Hook Industrial Complex. Our refined products operationsutilize our integrated pipeline and terminalling assets, as well as acquisition and marketing activities, to service refined products markets in several regions inthe United States.Crude Oil Transportation and Services SegmentOur crude oil operations provide transportation, terminalling and acquisition and marketing services to crude oil markets throughout the southwest, midwestand northeastern United States. Included within the operations are approximately 9,360 miles of crude oil trunk and gathering pipelines in the southwest andmidwest United States and equity ownership interests in two crude oil pipelines. Our crude oil terminalling services operate with an aggregate storagecapacity of approximately 33 million Bbls, including approximately 26 million Bbls at our Gulf Coast terminal in Nederland, Texas and approximately 3million Bbls at our5 Table of ContentsFort Mifflin terminal complex in Pennsylvania. Our crude oil acquisition and marketing activities utilize our pipeline and terminal assets, our proprietaryfleet crude oil tractor trailers and truck unloading facilities, as well as third-party assets, to service crude oil markets principally in the mid-continent UnitedStates.Revenues throughout our crude oil pipeline systems are generated from tariffs paid by shippers utilizing our transportation services. These tariffs are filedwith the FERC and other state regulatory agencies, as applicable.Our crude oil acquisition and marketing activities include the gathering, purchasing, marketing and selling of crude oil primarily in the mid-continent UnitedStates. Specifically, the crude oil acquisition and marketing activities include:•purchasing crude oil at both the wellhead from producers, and in bulk from aggregators at major pipeline interconnections and trading locations;•storing inventory during contango market conditions (when the price of crude oil for future delivery is higher than current prices);•buying and selling crude oil of different grades, at different locations in order to maximize value;•transporting crude oil using the pipelines, terminals and trucks or, when necessary or cost effective, pipelines, terminals or trucks owned and operated bythird parties; and•marketing crude oil to major integrated oil companies, independent refiners and resellers through various types of sale and exchange transactions.In November 2016, we purchased a crude oil acquisition and marketing business from Vitol, with operations based in the Permian Basin, Texas. Included inthe acquisition was a significant acreage dedication from an investment-grade Permian producer.All Other SegmentSegments below the quantitative thresholds are classified as “All other.” These include the following:•We own an equity method investment in limited partnership units of Sunoco LP.

Dakota Access and ETCO are collectively referred to as the “Bakken Pipeline.” The Bakken Pipeline is a 1,915 mile pipeline with aninitial capacity of 470 MBbls/d, expandable to 570 MBbls/d, that transports domestically produced crude oil from the Bakken/Three Forks productionareas in North Dakota to a storage and terminal hub outside of Patoka, Illinois, or to gulf coast connections including our crude terminal in NederlandTexas.The pipeline transports light, sweet crude oil from North Dakota to major refining markets in the Midwest and Gulf Coast regions.Dakota Access went into service on June 1, 2017 and consists of approximately 1,172 miles of 30-inch diameter pipeline traversing North Dakota, SouthDakota, Iowa and Illinois. Crude oil transported on the Dakota Access originates at six terminal locations in the North Dakota counties of Mountrail,Williams and McKenzie. The pipeline delivers the crude oil to a hub outside of Patoka, Illinois where it can be delivered to the ETCO Pipeline fordelivery to the Gulf Coast, or can be transported via other pipelines to refining markets throughout the Midwest.ETCO went into service on June 1, 2017 and consists of more than 743 miles consisting of 678 miles of mostly 30-inch converted natural gas pipelineand 65 miles of new 30-inch pipeline from Patoka, Illinois to Nederland, Texas, where the crude oil can be refined or further transported to additionalrefining markets.•Bayou Bridge Pipeline. The Bayou Bridge Pipeline is a joint venture between ETP and Phillips 66, in which ETP has a 60% ownership interest andserves as the operator of the pipeline. Phase I of the pipeline, which consists of a 30-inch pipeline from Nederland, Texas to Lake Charles, Louisiana,went into service in April 2016. Phase II of the pipeline, which will consist of 24-inch pipe from Lake Charles, Louisiana to St. James, Louisiana, isexpected to be completed in the second half of 2018.When completed the Bayou Bridge Pipeline will have a capacity expandable to approximately 480 MBbls/d of light and heavy crude oil from differentsources to the St. James crude oil hub, which is home to important refineries located in the Gulf Coast region.•Permian Express Pipelines. The Permian Express pipelines are part of the PEP joint venture and include Permian Express 1, Permian Express 2, PermianLongview and Louisiana Access pipelines, as well as the Longview to Louisiana and Pegasus pipelines contributed to this joint venture by ExxonMobil.These pipelines are comprised of crude oil trunk pipelines and crude oil gathering pipelines in Texas and Oklahoma and provide takeaway capacity fromthe Permian Basin, which origins in multiple locations in Western Texas.•Other Crude Oil pipelines include the Mid-Valley pipeline system which originates in Longview, Texas and passes through Louisiana, Arkansas,Mississippi, Tennessee, Kentucky and Ohio and terminates in Samaria, Michigan. This pipeline provides crude oil to a number of refineries, primarily inthe Midwest United States.In addition, we own a crude oil pipeline that runs from Marysville, Michigan to Toledo, Ohio, and a truck injection point for local production atMarysville. This pipeline receives crude oil from the Enbridge pipeline system for delivery to refineries located in Toledo, Ohio and to MPLX’s Samaria,Michigan tank farm, which supplies its Marathon Petroleum Corporation’s refinery in Detroit, Michigan.We also own and operate crude oil pipeline and gathering systems in Oklahoma. We have the ability to deliver substantially all of the crude oil gatheredon our Oklahoma system to Cushing. We are one of the largest purchasers of crude oil from producers in the state, and our crude oil acquisition andmarketing activities business is the primary shipper on our Oklahoma crude oil system.Crude Oil Terminals•Nederland. The Nederland terminal, located on the Sabine-Neches waterway between Beaumont and Port Arthur, Texas, is a large marine terminalproviding storage and distribution services for refiners and other large transporters of crude oil and NGLs. The terminal receives, stores, and distributescrude oil, NGLs, feedstocks, lubricants, petrochemicals, and bunker oils (used for fueling ships and other marine vessels), and also blends lubricants. Theterminal currently has a total storage capacity of approximately 26 million Bbls in approximately 150 above ground storage tanks with individualcapacities of up to 660 MBbls.The Nederland terminal can receive crude oil at four of its five ship docks and four barge berths. The four ship docks are capable of receiving over 2million Bbls/d of crude oil. In addition to our crude oil pipelines, the terminal can also receive crude oil through a number of other pipelines, includingthe DOE. The DOE pipelines connect the terminal to the United States Strategic Petroleum Reserve’s West Hackberry caverns at Hackberry, Louisianaand Big Hill caverns near Winnie, Texas, which have an aggregate storage capacity of approximately 395 million Bbls.15 Table of ContentsThe Nederland Terminal can deliver crude oil and other petroleum products via pipeline, barge and ship. The terminal has two ship docks and threebarge berths that are capable of delivering crude oils for international transport. In total, the terminal is capable of delivering over 2 million Bbls/d ofcrude oil to our crude oil pipelines or a number of third-party pipelines including the DOE. The Nederland terminal generates crude oil revenuesprimarily by providing term or spot storage services and throughput capabilities to a number of customers.•Fort Mifflin. The Fort Mifflin terminal complex is located on the Delaware River in Philadelphia, Pennsylvania and includes the Fort Mifflin terminal,the Hog Island wharf, the Darby Creek tank farm and connecting pipelines. Revenues are generated from the Fort Mifflin terminal complex by chargingfees based on throughput.The Fort Mifflin terminal contains two ship docks with freshwater drafts and a total storage capacity of approximately 570 MBbls. Crude oil and somerefined products enter the Fort Mifflin terminal primarily from marine vessels on the Delaware River. One Fort Mifflin dock is designed to handle crudeoil from very large crude carrier-class tankers and smaller crude oil vessels. The other dock can accommodate only smaller crude oil vessels.The Hog Island wharf is located next to the Fort Mifflin terminal on the Delaware River and receives crude oil via two ship docks, one of which canaccommodate crude oil tankers and smaller crude oil vessels, and the other of which can accommodate some smaller crude oil vessels.The Darby Creek tank farm is a primary crude oil storage terminal for the Philadelphia refinery, which is operated by PES under a joint venture withSunoco, Inc. This facility has a total storage capacity of approximately 3 million Bbls. Darby Creek receives crude oil from the Fort Mifflin terminal andHog Island wharf via our pipelines. The tank farm then stores the crude oil and transports it to the PES refinery via our pipelines.•Eagle Point. The Eagle Point terminal is located in Westville, New Jersey and consists of docks, truck loading facilities and a tank farm. The docks arelocated on the Delaware River and can accommodate three marine vessels (ships or barges) to receive and deliver crude oil, intermediate products andrefined products to outbound ships and barges. The tank farm has a total active storage capacity of approximately 1 million Bbls and can receive crudeoil via barge and rail and deliver via ship and barge, providing customers with access to various markets. The terminal generates revenue primarily bycharging fees based on throughput, blending services and storage.•Midland. The Midland terminal is located in Midland, Texas and was acquired in November 2016 from Vitol. The facility includes approximately 2million Bbls of crude oil storage, a combined 14 lanes of truck loading and unloading, and provides access to the Permian Express 2 transportationsystem.•Marcus Hook Industrial Complex.

The terminal has a total active crude oil storage capacity of approximately 1 million Bbls.•Patoka, Illinois Terminal. The Patoka, Illinois terminal is a tank farm and was contributed by ExxonMobil to the PEP joint venture and is located inMarion County, Illinois. The facility includes 234 acres of owned land and provides for approximately 2 million Bbls of crude oil storage.Crude Oil Acquisition and MarketingOur crude oil acquisition and marketing operations are conducted using our assets, which include approximately 370 crude oil transport trucks andapproximately 150 crude oil truck unloading facilities, as well as third-party truck, rail and marine assets.All OtherThe following details our assets in the all other segment.Equity Method Investments•Sunoco LP. We have an equity method investment in limited partnership units of Sunoco LP. As of December 31, 2017, our investment consisted of 43.5million units, representing 43.6% of Sunoco LP’s total outstanding common units. Subsequent to Sunoco LP’s repurchase of a portion of its commonunits on February 7, 2018, our investment consists of 26.2 million units, representing 31.8% of Sunoco LP’s total outstanding common units.•PES. We have a non-controlling interest in PES, comprising 33% of PES’ outstanding common units. As discussed in “Segment Overview - All Other”above, PES Holdings and eight affiliates filed for Chapter 11 bankruptcy protection on January 21, 2018.16 Table of ContentsContract Services OperationsWe own and operate a fleet of equipment used to provide treating services, such as carbon dioxide and hydrogen sulfide removal, natural gas cooling,dehydration and BTU management. Our contract treating services are primarily located in Texas, Louisiana and Arkansas.CompressionWe own all of the outstanding equity interests of CDM, which operates a natural gas compression equipment business with operations in Arkansas,California, Colorado, Louisiana, New Mexico, Oklahoma, Pennsylvania and Texas. As discussed in “Strategic Transactions,” in January 2018, we enteredinto an agreement to contribute CDM to USAC.We own 100% of the membership interests of ETG, which owns all of the partnership interests of ETT. ETT provides compression services to customersengaged in the transportation of natural gas, including our other segments.Natural Resources OperationsOur Natural Resources operations primarily involve the management and leasing of coal properties and the subsequent collection of royalties. We also earnrevenues from other land management activities, such as selling standing timber, leasing fee-based coal-related infrastructure facilities to certain lessees andend-user industrial plants, collecting oil and gas royalties and from coal transportation, or wheelage fees. As of December 31, 2017, we owned or controlledapproximately 766 million tons of proven and probable coal reserves in central and northern Appalachia, properties in eastern Kentucky, southwesternVirginia and southern West Virginia, and in the Illinois Basin, properties in southern Illinois, Indiana, and western Kentucky and as the operator of end-usercoal handling facilities.Liquefaction ProjectLCL, an entity whose parent is owned 60% by ETE and 40% by ETP, is in the process of developing a liquefaction project at the site of ETE’s existingregasification facility in Lake Charles, Louisiana. The project development agreement previously entered into in September 2013 with BG Group plc (now"Shell") related to this project expired in February 2017. On June 28, 2017, LCL signed a memorandum of understanding with Korea Gas Corporation andShell to study the feasibility of a joint development of the Lake Charles liquefaction project. The project would utilize existing dock and storage facilitiesowned by ETE located on the Lake Charles site. The parties’ determination as to the feasibility of the project will be particularly dependent upon theprospects for securing long-term contractual arrangements for the off-take of LNG which in turn will be dependent upon supply and demand factors affectingthe price of LNG in foreign markets. The financial viability of the project will also be dependent upon a number of other factors, including the expected costto construct the liquefaction facility, the terms and conditions of the financing for the construction of the liquefaction facility, the cost of the natural gassupply, the costs to transport natural gas to the liquefaction facility, the costs to operate the liquefaction facility and the costs to transport LNG from theliquefaction facility to customers in foreign markets (particularly Europe and Asia). Some of these costs fluctuate based on a variety of factors, includingsupply and demand factors affecting the price of natural gas in the United States, supply and demand factors affecting the costs for construction services forlarge infrastructure projects in the United States, and general economic conditions, there can be no assurance that the parties will determine to proceed todevelop this project.The liquefaction project is expected to consist of three LNG trains with a combined design nameplate outlet capacity of 16.45 metric tonnes per annum. Oncecompleted, the liquefaction project will enable LCL to liquefy domestically produced natural gas and export it as LNG. By adding the new liquefactionfacility and integrating with the existing LNG regasification/import facility, the enhanced facility would become a bi-directional facility capable ofexporting and importing LNG. Shell is the sole customer for the existing regasification facility and is obligated to pay reservation fees for 100% of theregasification capacity regardless of whether it actually utilizes such capacity pursuant to a regasification services agreement that terminates in 2030. Theliquefaction project would be constructed on 440 acres of land, of which 80 acres are owned by Lake Charles LNG and the remaining acres are to be leased byLCL under a long-term lease from the Lake Charles Harbor and Terminal District.The export of LNG produced by the liquefaction project from the United States would be undertaken under long-term export authorizations issued by theDOE to LCL. In March 2013, LCL obtained a DOE authorization to export LNG to countries with which the United States has or will have Free TradeAgreements (“FTA”) for trade in natural gas (the “FTA Authorization”). In July 2016, LCL also obtained a conditional DOE authorization to export LNG tocountries that do not have an FTA for trade in natural gas (the “Non-FTA Authorization”). The FTA Authorization and Non-FTA Authorization have 25- and20-year terms, respectively. We have received our wetlands permits from the United States Army Corps of Engineers (“USACE”) to perform wetlands mitigation work and to performmodification and dredging work for the temporary and permanent dock facilities at the Lake Charles LNG facilities.17 Table of ContentsBusiness StrategyWe have designed our business strategy with the goal of creating and maximizing value to our Unitholders.

We believe that by pursuing independent operating and growth strategies we will be best positioned to achieve ourobjectives. We balance our desire for growth with our goal of preserving a strong balance sheet, ample liquidity and investment grade credit metrics.Following is a summary of the business strategies of our core businesses:Growth through acquisitions. We intend to continue to make strategic acquisitions that offer the opportunity for operational efficiencies and the potentialfor increased utilization and expansion of our existing assets while supporting our investment grade credit ratings.Engage in construction and expansion opportunities. We intend to leverage our existing infrastructure and customer relationships by constructing andexpanding systems to meet new or increased demand for midstream and transportation services.Increase cash flow from fee-based businesses. We intend to increase the percentage of our business conducted with third parties under fee-basedarrangements in order to provide for stable, consistent cash flows over long contract periods while reducing exposure to changes in commodity prices.Enhance profitability of existing assets. We intend to increase the profitability of our existing asset base by adding new volumes under long-term producercommitments, undertaking additional initiatives to enhance utilization and reducing costs by improving operations.CompetitionNatural GasThe business of providing natural gas gathering, compression, treating, transportation, storage and marketing services is highly competitive. Since pipelinesare generally the only practical mode of transportation for natural gas over land, the most significant competitors of our transportation and storage segmentare other pipelines. Pipelines typically compete with each other based on location, capacity, price and reliability.We face competition with respect to retaining and obtaining significant natural gas supplies under terms favorable to us for the gathering, treating andmarketing portions of our business. Our competitors include major integrated oil companies, interstate and intrastate pipelines and other companies thatgather, compress, treat, process, transport and market natural gas. Many of our competitors, such as major oil and gas and pipeline companies, have capitalresources and control supplies of natural gas substantially greater than ours.In marketing natural gas, we have numerous competitors, including marketing affiliates of interstate pipelines, major integrated oil companies, and local andnational natural gas gatherers, brokers and marketers of widely varying sizes, financial resources and experience. Local utilities and distributors of natural gasare, in some cases, engaged directly, and through affiliates, in marketing activities that compete with our marketing operations.NGLIn markets served by our NGL pipelines, we face competition with other pipeline companies, including those affiliated with major oil, petrochemical andnatural gas companies, and barge, rail and truck fleet operations. In general, our NGL pipelines compete with these entities in terms of transportation fees,reliability and quality of customer service. We face competition with other storage facilities based on fees charged and the ability to receive and distributethe customer’s products. We compete with a number of NGL fractionators in Texas and Louisiana. Competition for such services is primarily based on thefractionation fee charged.Crude Oil and ProductsIn markets served by our products and crude oil pipelines, we face competition from other pipelines as well as rail and truck transportation. Generally,pipelines are the lowest cost method for long-haul, overland movement of products and crude oil. Therefore, the most significant competitors for largevolume shipments in the areas served by our pipelines are other pipelines.18 Table of ContentsIn addition, pipeline operations face competition from rail and trucks that deliver products in a number of areas that our pipeline operations serve. While theircosts may not be competitive for longer hauls or large volume shipments, rail and trucks compete effectively for incremental and marginal volume in manyareas served by our pipelines.With respect to competition from other pipelines, the primary competitive factors consist of transportation charges, access to crude oil supply and marketdemand. Competitive factors in crude oil purchasing and marketing include price and contract flexibility, quantity and quality of services, and accessibilityto end markets.Our refined product terminals compete with other independent terminals with respect to price, versatility and services provided. The competition primarilycomes from integrated petroleum companies, refining and marketing companies, independent terminal companies and distribution companies with marketingand trading operations.Credit Risk and CustomersCredit risk refers to the risk that a counterparty may default on its contractual obligations resulting in a loss to the Partnership. Credit policies have beenapproved and implemented to govern the Partnership’s portfolio of counterparties with the objective of mitigating credit losses. These policies establishguidelines, controls and limits to manage credit risk within approved tolerances by mandating an appropriate evaluation of the financial condition ofexisting and potential counterparties, monitoring agency credit ratings, and by implementing credit practices that limit exposure according to the riskprofiles of the counterparties. Furthermore, the Partnership may, at times, require collateral under certain circumstances to mitigate credit risk as necessary.The Partnership also uses industry standard commercial agreements which allow for the netting of exposures associated with transactions executed under asingle commercial agreement. Additionally, we utilize master netting agreements to offset credit exposure across multiple commercial agreements with asingle counterparty or affiliated group of counterparties.The Partnership’s counterparties consist of a diverse portfolio of customers across the energy industry, including petrochemical companies, commercial andindustrials, oil and gas producers, municipalities, gas and electric utilities, midstream companies and independent power generators. Our overall exposuremay be affected positively or negatively by macroeconomic or regulatory changes that impact our counterparties to one extent or another. Currently,management does not anticipate a material adverse effect in our financial position or results of operations as a consequence of counterparty non-performance.Our natural gas transportation and midstream revenues are derived significantly from companies that engage in exploration and production activities. Thediscovery and development of new shale formations across the United States has created an abundance of natural gas and crude oil resulting in a negativeimpact on prices in recent years for natural gas and crude oil. As a result, some of our exploration and production customers have been adversely impacted;however, we are monitoring these customers and mitigating credit risk as necessary.During the year ended December 31, 2017, none of our customers individually accounted for more than 10% of our consolidated revenues.Regulation of Interstate Natural Gas Pipelines. The FERC has broad regulatory authority over the business and operations of interstate natural gaspipelines. Under the Natural Gas Act (“NGA”), the FERC generally regulates the transportation of natural gas in interstate commerce. For FERC regulatorypurposes, “transportation” includes natural gas pipeline transmission (forwardhauls and backhauls), storage and other services. The Florida Gas Transmission,Transwestern, Panhandle Eastern, Trunkline Gas, Tiger, Fayetteville Express, Sea Robin, Gulf States and Midcontinent Express pipelines transport natural gasin interstate commerce and thus each qualifies as a “natural-gas company” under the NGA subject to the FERC’s regulatory jurisdiction. We also hold certainnatural gas storage facilities that are subject to the FERC’s regulatory oversight under the NGA.The FERC’s NGA authority includes the power to:•approve the siting, construction and operation of new facilities;•review and approve transportation rates;•determine the types of services our regulated assets are permitted to perform;•regulate the terms and conditions associated with these services;•permit the extension or abandonment of services and facilities;•require the maintenance of accounts and records; and•authorize the acquisition and disposition of facilities.19 Table of ContentsUnder the NGA, interstate natural gas companies must charge rates that are just and reasonable. In addition, the NGA prohibits natural gas companies fromunduly preferring or unreasonably discriminating against any person with respect to pipeline rates or terms and conditions of service.The maximum rates to be charged by NGA-jurisdictional natural gas companies and their terms and conditions for service are required to be on file with theFERC. Most natural gas companies are authorized to offer discounts from their FERC-approved maximum just and reasonable rates when competitionwarrants such discounts. Natural gas companies are also generally permitted to offer negotiated rates different from rates established in their tariff if, amongother requirements, such companies’ tariffs offer a cost-based recourse rate to a prospective shipper as an alternative to the negotiated rate. Natural gascompanies must make offers of rate discounts and negotiated rates on a basis that is not unduly discriminatory. Existing tariff rates may be challenged bycomplaint or on the FERC’s own motion, and if found unjust and unreasonable, may be altered on a prospective basis from no earlier than the date of thecomplaint or initiation of a proceeding by the FERC. The FERC must also approve all rate changes. We cannot guarantee that the FERC will allow us tocharge rates that fully recover our costs or continue to pursue its approach of pro-competitive policies.For two of our NGA-jurisdictional natural gas companies, Tiger and Fayetteville Express, the large majority of capacity in those pipelines is subscribed forlengthy terms under FERC-approved negotiated rates. However, as indicated above, cost-based recourse rates are also offered under their respective tariffs.Pursuant to the FERC’s rules promulgated under the Energy Policy Act of 2005, it is unlawful for any entity, directly or indirectly, in connection with thepurchase or sale of electric energy or natural gas or the purchase or sale of transmission or transportation services subject to FERC jurisdiction: (i) to defraudusing any device, scheme or artifice; (ii) to make any untrue statement of material fact or omit a material fact; or (iii) to engage in any act, practice or courseof business that operates or would operate as a fraud or deceit. The Commodity Futures Trading Commission (“CFTC”) also holds authority to monitorcertain segments of the physical and futures energy commodities market pursuant to the Commodity Exchange Act (“CEA”). With regard to our physicalpurchases and sales of natural gas, NGLs or other energy commodities; our gathering or transportation of these energy commodities; and any related hedgingactivities that we undertake, we are required to observe these anti-market manipulation laws and related regulations enforced by the FERC and/or the CFTC.These agencies hold substantial enforcement authority, including the ability to assess or seek civil penalties of up to approximately $1 million per day perviolation, to order disgorgement of profits and to recommend criminal penalties. Should we violate the anti-market manipulation laws and regulations, wecould also be subject to related third-party damage claims by, among others, sellers, royalty owners and taxing authorities.Failure to comply with the NGA, the Energy Policy Act of 2005, the CEA and the other federal laws and regulations governing our operations and businessactivities can result in the imposition of administrative, civil and criminal remedies.Regulation of Intrastate Natural Gas and NGL Pipelines. Intrastate transportation of natural gas and NGLs is largely regulated by the state in which suchtransportation takes place. To the extent that our intrastate natural gas transportation systems transport natural gas in interstate commerce, the rates and termsand conditions of such services are subject to FERC jurisdiction under Section 311 of the Natural Gas Policy Act (“NGPA”). The NGPA regulates, amongother things, the provision of transportation services by an intrastate natural gas pipeline on behalf of a local distribution company or an interstate natural gaspipeline. The rates and terms and conditions of some transportation and storage services provided on the Oasis pipeline, HPL System, East Texas pipeline, ETFuel System, Trans-Pecos and Comanche Trail are subject to FERC regulation pursuant to Section 311 of the NGPA. Under Section 311, rates charged forintrastate transportation must be fair and equitable, and amounts collected in excess of fair and equitable rates are subject to refund with interest. The termsand conditions of service set forth in the intrastate facility’s statement of operating conditions are also subject to FERC review and approval. Should theFERC determine not to authorize rates equal to or greater than our currently approved Section 311 rates, our business may be adversely affected. Failure toobserve the service limitations applicable to transportation and storage services under Section 311, failure to comply with the rates approved by the FERC forSection 311 service, and failure to comply with the terms and conditions of service established in the pipeline’s FERC-approved statement of operatingconditions could result in an alteration of jurisdictional status, and/or the imposition of administrative, civil and criminal remedies.Our intrastate natural gas operations are also subject to regulation by various agencies in Texas, principally the TRRC. Our intrastate pipeline and storageoperations in Texas are also subject to the Texas Utilities Code, as implemented by the TRRC. Generally, the TRRC is vested with authority to ensure thatrates, operations and services of gas utilities, including intrastate pipelines, are just and reasonable and not discriminatory. The rates we charge fortransportation services are deemed just and reasonable under Texas law unless challenged in a customer or TRRC complaint. We cannot predict whether sucha complaint will be filed against us or whether the TRRC will change its regulation of these rates. Failure to comply with the Texas Utilities Code can resultin the imposition of administrative, civil and criminal remedies.20 Table of ContentsOur NGL pipelines and operations may also be or become subject to state public utility or related jurisdiction which could impose additional safety andoperational regulations relating to the design, siting, installation, testing, construction, operation, replacement and management of NGL gathering facilities.In addition, the rates, terms and conditions for shipments of NGLs on our pipelines are subject to regulation by FERC under the Interstate Commerce Act(“ICA”) and the Energy Policy Act of 1992 (the “EPAct of 1992”) if the NGLs are transported in interstate or foreign commerce whether by our pipelines orother means of transportation. Since we do not control the entire transportation path of all NGLs shipped on our pipelines, FERC regulation could betriggered by our customers’ transportation decisions.Regulation of Sales of Natural Gas and NGLs. The price at which we buy and sell natural gas currently is not subject to federal regulation and, for the mostpart, is not subject to state regulation. The price at which we sell NGLs is not subject to federal or state regulation.To the extent that we enter into transportation contracts with natural gas pipelines that are subject to FERC regulation, we are subject to FERC requirementsrelated to the use of such capacity. Any failure on our part to comply with the FERC’s regulations and policies, or with an interstate pipeline’s tariff, couldresult in the imposition of civil and criminal penalties.Our sales of natural gas are affected by the availability, terms and cost of pipeline transportation. As noted above, the price and terms of access to pipelinetransportation are subject to extensive federal and state regulation. The FERC is continually proposing and implementing new rules and regulations affectingthose segments of the natural gas industry. These initiatives also may affect the intrastate transportation of natural gas under certain circumstances. The statedpurpose of many of these regulatory changes is to promote competition among the various sectors of the natural gas industry and these initiatives generallyreflect more light-handed regulation. We cannot predict the ultimate impact of these regulatory changes to our natural gas marketing operations, and we notethat some of the FERC’s regulatory changes may adversely affect the availability and reliability of interruptible transportation service on interstate pipelines.We do not believe that we will be affected by any such FERC action in a manner that is materially different from other natural gas marketers with whom wecompete.Regulation of Gathering Pipelines. Section 1(b) of the NGA exempts natural gas gathering facilities from the jurisdiction of the FERC under the NGA. Weown a number of natural gas pipelines in Texas, Louisiana and West Virginia that we believe meet the traditional tests the FERC uses to establish a pipeline’sstatus as a gathering pipeline not subject to FERC jurisdiction. However, the distinction between FERC-regulated transmission services and federallyunregulated gathering services has been the subject of substantial litigation and varying interpretations, so the classification and regulation of our gatheringfacilities could be subject to change based on future determinations by the FERC, the courts and Congress. State regulation of gathering facilities generallyincludes various safety, environmental and, in some circumstances, nondiscriminatory take requirements and complaint-based rate regulation.In Texas, our gathering facilities are subject to regulation by the TRRC under the Texas Utilities Code in the same manner as described above for ourintrastate pipeline facilities. Louisiana’s Pipeline Operations Section of the Department of Natural Resources’ Office of Conservation is generally responsiblefor regulating intrastate pipelines and gathering facilities in Louisiana and has authority to review and authorize natural gas transportation transactions andthe construction, acquisition, abandonment and interconnection of physical facilities.Historically, apart from pipeline safety, Louisiana has not acted to exercise this jurisdiction respecting gathering facilities. In Louisiana, our Chalkley Systemis regulated as an intrastate transporter, and the Louisiana Office of Conservation has determined that our Whiskey Bay System is a gathering system.We are subject to state ratable take and common purchaser statutes in all of the states in which we operate. The ratable take statutes generally requiregatherers to take, without undue discrimination, natural gas production that may be tendered to the gatherer for handling. Similarly, common purchaserstatutes generally require gatherers to purchase without undue discrimination as to source of supply or producer. These statutes are designed to prohibitdiscrimination in favor of one producer over another producer or one source of supply over another source of supply. These statutes have the effect ofrestricting the right of an owner of gathering facilities to decide with whom it contracts to purchase or transport natural gas.Natural gas gathering may receive greater regulatory scrutiny at both the state and federal levels. For example, the TRRC has approved changes to itsregulations governing transportation and gathering services performed by intrastate pipelines and gatherers, which prohibit such entities from undulydiscriminating in favor of their affiliates. Many of the producing states have adopted some form of complaint-based regulation that generally allows naturalgas producers and shippers to file complaints with state regulators in an effort to resolve grievances relating to natural gas gathering access and ratediscrimination allegations. Our gathering operations could be adversely affected should they be subject in the future to the application of additional ordifferent state or federal regulation of rates and services. Our gathering operations also may be or become subject to safety and operational regulationsrelating to the design, installation, testing, construction, operation, replacement and management of gathering facilities. Additional rules and legislationpertaining to these matters are considered or adopted from time to time. We cannot predict what effect, if any,21 Table of Contentssuch changes might have on our operations, but the industry could be required to incur additional capital expenditures and increased costs depending onfuture legislative and regulatory changes.Regulation of Interstate Crude Oil, NGL and Products Pipelines. Interstate common carrier pipeline operations are subject to rate regulation by the FERCunder the ICA, the EPAct of 1992, and related rules and orders. The ICA requires that tariff rates for petroleum pipelines be “just and reasonable” and notunduly discriminatory and that such rates and terms and conditions of service be filed with the FERC. This statute also permits interested persons tochallenge proposed new or changed rates. The FERC is authorized to suspend the effectiveness of such rates for up to seven months, though rates aretypically not suspended for the maximum allowable period. If the FERC finds that the new or changed rate is unlawful, it may require the carrier to payrefunds for the period that the rate was in effect. The FERC also may investigate, upon complaint or on its own motion, rates that are already in effect and mayorder a carrier to change its rates prospectively. Upon an appropriate showing, a shipper may obtain reparations for damages sustained for a period of up totwo years prior to the filing of a complaint.The FERC generally has not investigated interstate rates on its own initiative when those rates, like those we charge, have not been the subject of a protest ora complaint by a shipper. However, the FERC could investigate our rates at the urging of a third party if the third party is either a current shipper or has asubstantial economic interest in the tariff rate level. Although no assurance can be given that the tariff rates charged by us ultimately will be upheld ifchallenged, management believes that the tariff rates now in effect for our pipelines are within the maximum rates allowed under current FERC policies andprecedents.For many locations served by our product and crude pipelines, we are able to establish negotiated rates. Otherwise, we are permitted to charge cost-basedrates, or in many cases, grandfathered rates based on historical charges or settlements with our customers. To the extent we rely on cost-of-service ratemakingto establish or support our rates, the issue of the proper allowance for federal and state income taxes could arise. In 2005, FERC issued a policy statementstating that it would permit common carriers, among others, to include an income tax allowance in cost-of-service rates to reflect actual or potential taxliability attributable to a regulated entity’s operating income, regardless of the form of ownership. Under FERC’s policy, a tax pass-through entity seekingsuch an income tax allowance must establish that its partners or members have an actual or potential income tax liability on the regulated entity’s income.Whether a pipeline’s owners have such actual or potential income tax liability is subject to review by FERC on a case-by-case basis. Although this policy isgenerally favorable for common carriers that are organized as pass-through entities, it still entails rate risk due to the FERC’s case-by-case review approach.The application of this policy, as well as any decision by FERC regarding our cost of service, may also be subject to review in the courts. In December 2016,FERC issued a Notice of Inquiry Regarding the Commission’s Policy for Recovery of Income Tax Costs. FERC requested comments regarding how to addressany double recovery resulting from the Commission’s current income tax allowance and rate of return policies. The comment period with respect to the noticeof inquiry ended on April 7, 2017. The outcome of the inquiry is still pending.Effective January 2018, the 2017 Tax Cuts and Jobs Act changed several provisions of the federal tax code, including a reduction in the maximum corporatetax rate. With the lower tax rate, the maximum tariff rates allowed by FERC under its rate base methodology for master limited partnerships may be impactedby a lower income tax allowance component. Many of our interstate pipelines, such as Tiger, MEP and FEP, have negotiated market rates that were agreed toby customers in connection with long-term contracts entered into to support the construction of the pipelines. Other systems, such as FGT, Transwestern andPEPL, have a mix of tariff rate, discount rate, and negotiated rate agreements. In addition, several of these pipelines are covered by approved settlements,where rate filings will be made in the future. As such, the timing and impact of these systems of any tax change is unknown at this time.EPAct of 1992 required FERC to establish a simplified and generally applicable methodology to adjust tariff rates for inflation for interstate petroleumpipelines. As a result, FERC adopted an indexing rate methodology which, as currently in effect, allows common carriers to change their rates withinprescribed ceiling levels that are tied to changes in the Producer Price Index for Finished Goods, or PPIFG. FERC’s indexing methodology is subject toreview every five years. During the five-year period commencing July 1, 2011 and ending June 30, 2016, common carriers charging indexed rates arepermitted to adjust their indexed ceilings annually by PPIFG plus 2.65%. Beginning July 1, 2016, the indexing method provided for annual changes equal tothe change in PPIFG plus 1.23%. The indexing methodology is applicable to existing rates, including grandfathered rates, with the exclusion of market-basedrates. A pipeline is not required to raise its rates up to the index ceiling, but it is permitted to do so and rate increases made under the index are presumed tobe just and reasonable unless a protesting party can demonstrate that the portion of the rate increase resulting from application of the index is substantially inexcess of the pipeline’s increase in costs. Under the indexing rate methodology, in any year in which the index is negative, pipelines must file to lower theirrates if those rates would otherwise be above the rate ceiling. In October 2016, FERC issued an Advance Notice of Proposed Rulemaking seeking commenton a number of proposals, including: (1) whether the Commission should deny any increase in a rate ceiling or annual index-based rate increase if apipeline’s revenues exceed total costs by 15% for the prior two years; (2) a new percentage comparison test that would deny a proposed increase to apipeline’s rate or ceiling level greater than 5% above the barrel-mile cost changes; and (3) a requirement that all pipelines file indexed ceiling levelsannually, with the ceiling levels subject to challenge22 Table of Contentsand restricting the pipeline’s ability to carry forward the full indexed increase to a future period. The comment period with respect to the proposed rulesended on March 17, 2017. FERC has taken no further action on the proposed rule to date.Finally, in November 2017 FERC responded to a petition for declaratory order and issued an order that may have significant impacts on the way a marketer ofcrude oil or petroleum products that is affiliated with an interstate pipeline can price its services if those services include transportation on an affiliate’sinterstate pipeline. In particular, FERC’s November 2017 order prohibits buy/sell arrangements by a marketing affiliate if: (i) the transportation differentialapplicable to its affiliate’s interstate pipeline transportation service is at a discount to the affiliated pipeline’s filed rate for that service; and (ii) the pipelineaffiliate subsidizes the loss. Several parties have requested that FERC clarify its November 2017 order or, in the alternative, grant rehearing of the November2017 order. We are unable to predict how FERC will respond to such requests. Depending on how FERC responds, it could have an impact on the rates weare permitted to charge.Regulation of Intrastate Crude Oil, NGL and Products Pipelines. Some of our crude oil, NGL and products pipelines are subject to regulation by the TRRC,the PA PUC, and the Oklahoma Corporation Commission. The operations of our joint venture interests are also subject to regulation in the states in whichthey operate. The applicable state statutes require that pipeline rates be nondiscriminatory and provide no more than a fair return on the aggregate value ofthe pipeline property used to render services. State commissions generally have not initiated an investigation of rates or practices of petroleum pipelines inthe absence of shipper complaints. Complaints to state agencies have been infrequent and are usually resolved informally. Although management cannot becertain that our intrastate rates ultimately would be upheld if challenged, we believe that, given this history, the tariffs now in effect are not likely to bechallenged or, if challenged, are not likely to be ordered to be reduced.In addition, as noted above, the rates, terms and conditions for shipments of crude oil, NGLs or products on our pipelines could be subject to regulation byFERC under the ICA and the EPAct of 1992 if the crude oil, NGLs or products are transported in interstate or foreign commerce whether by our pipelines orother means of transportation. Since we do not control the entire transportation path of all crude oil, NGLs or products shipped on our pipelines, FERCregulation could be triggered by our customers’ transportation decisions.Regulation of Pipeline Safety. Our pipeline operations are subject to regulation by the DOT, through the PHMSA, pursuant to the Natural Gas PipelineSafety Act of 1968, as amended (“NGPSA”), with respect to natural gas and the Hazardous Liquids Pipeline Safety Act of 1979, as amended (“HLPSA”), withrespect to crude oil, NGLs and condensates. The NGPSA and HLPSA, as amended, govern the design, installation, testing, construction, operation,replacement and management of natural gas as well as crude oil, NGL and condensate pipeline facilities. Pursuant to these acts, PHMSA has promulgatedregulations governing pipeline wall thickness, design pressures, maximum operating pressures, pipeline patrols and leak surveys, minimum depthrequirements, and emergency procedures, as well as other matters intended to ensure adequate protection for the public and to prevent accidents and failures.Additionally, PHMSA has established a series of rules requiring pipeline operators to develop and implement integrity management programs for certain gasand hazardous liquid pipelines that, in the event of a pipeline leak or rupture, could affect high consequence areas (“HCAs”), which are areas where a releasecould have the most significant adverse consequences, including high population areas, certain drinking water sources and unusually sensitive ecologicalareas. Failure to comply with the pipeline safety laws and regulations may result in the assessment of sanctions, including administrative, civil or criminalpenalties, the imposition of investigatory, remedial or corrective action obligations, the occurrence of delays in permitting or the performance of projects, orthe issuance of injunctions limiting or prohibiting some or all of our operations in the affected area.The HLPSA and NGPSA have been amended by the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (“2011 Pipeline Safety Act”) and theProtecting Our Infrastructure of Pipelines and Enhancing Safety Act of 2016 (“2016 Pipeline Safety Act”). The 2011 Pipeline Safety Act increased thepenalties for safety violations, established additional safety requirements for newly constructed pipelines and required studies of safety issues that couldresult in the adoption of new regulatory requirements by PHMSA for existing pipelines. The 2011 Pipeline Safety Act doubled the maximum administrativefines for safety violations from $100,000 to $200,000 for a single violation and from $1 million to $2 million for a related series of violations, but providedthat these maximum penalty caps do not apply to certain civil enforcement actions. Effective April 27, 2017, to account for inflation, those maximum civilpenalties were increased to $209,002 per day, with a maximum of $2,090,022 for a series of violations. The 2016 Pipeline Safety Act extended PHMSA’sstatutory mandate through 2019 and, among other things, requiring PHMSA to complete certain of its outstanding mandates under the 2011 Pipeline SafetyAct and developing new safety standards for natural gas storage facilities by June 22, 2018. The 2016 Pipeline Safety Act also empowers PHMSA to addressimminent hazards by imposing emergency restrictions, prohibitions and safety measures on owners and operators of hazardous liquid or natural gas pipelinefacilities without prior notice or an opportunity for a hearing. PHMSA issued interim regulations in October 2016 to implement the agency’s expandedauthority to address unsafe pipeline conditions or practices that pose an imminent hazard to life, property, or the environment.23 Table of ContentsIn addition, states have adopted regulations, similar to existing PHMSA regulations, for intrastate gathering and transmission lines. The states in which weconduct operations typically have developed regulatory programs that parallel the federal regulatory scheme and are applicable to intrastate pipelines. Undersuch state regulatory programs, states have the authority to conduct pipeline inspections, to investigate accidents and to oversee compliance andenforcement, safety programs and record maintenance and reporting. Congress, PHMSA and individual states may pass or implement additional safetyrequirements that could result in increased compliance costs for us and other companies in our industry. For example, federal construction, maintenance andinspection standards under the NGPSA that apply to pipelines in relatively populated areas may not apply to gathering lines running through rural regions.This “rural gathering exemption” under the NGPSA presently exempts substantial portions of our gathering facilities located outside of cities, towns or anyarea designated as residential or commercial from jurisdiction under the NGPSA, but does not apply to our intrastate natural gas pipelines. In recent years, thePHMSA has considered changes to this rural gathering exemption, including publishing an advance notice of proposed rulemaking relating to gas pipelinesin 2011, in which the agency sought public comment on possible changes to the definition of “high consequence areas” and “gathering lines” and thestrengthening of pipeline integrity management requirements. In April 2016, pursuant to one of the requirements of the 2011 Pipeline Safety Act, PHMSApublished a proposed rulemaking that, among other things, would expand certain of PHMSA’s current regulatory safety programs for natural gas pipelines innewly defined “moderate consequence areas” that contain as few as 5 dwellings within a potential impact area; require natural gas pipelines installed before1970 and thus excluded from certain pressure testing obligations to be tested to determine their maximum allowable operating pressures (“MAOP”); andrequire certain onshore and offshore gathering lines in Class I areas to comply with damage prevention, corrosion control, public education, MAOP limits,line markers and emergency planning standards. Additional requirements proposed by this proposed rulemaking would increase PHMSA’s integritymanagement requirements for natural gas pipelines and also require consideration of seismicity in evaluating threats to pipelines. PHMSA has not yetfinalized the March 2016 proposed rulemaking.In January 2017, PHMSA issued a final rule amending federal safety standards for hazardous liquid pipelines. The final rule is the latest step in a lengthyrulemaking process that began in 2010 with a request for comments and continued with publication of a rulemaking proposal in October 2015. The generaleffective date of this final rule is six months from publication in the Federal Register, but it is currently subject to further administrative review in connectionwith the transition of Presidential administrations and thus, implementation of this final rule remains uncertain. The final rule addresses several areasincluding reporting requirements for gravity and unregulated gathering lines, inspections after weather or climatic events, leak detection systemrequirements, revisions to repair criteria and other integrity management revisions. In addition, PHMSA issued regulations on January 23, 2017, on operatorqualification, cost recovery, accident and incident notification and other pipeline safety changes that are now effective. These regulations are also subject,however, to potential further review in connection with the transition of Presidential administrations. Historically, our pipeline safety costs have not had amaterial adverse effect on our business or results of operations but there is no assurance that such costs will not be material in the future, whether due toelimination of the rural gathering exemption or otherwise due to changes in pipeline safety laws and regulations.In another example of how future legal requirements could result in increased compliance costs, notwithstanding the applicability of the federal OSHA’sProcess Safety Management (“PSM”) regulations and the EPA’s Risk Management Planning (“RMP”) requirements at regulated facilities, PHMSA and one ormore state regulators, including the Texas Railroad Commission, have in recent years, expanded the scope of their regulatory inspections to include certainin-plant equipment and pipelines found within NGL fractionation facilities and associated storage facilities, in order to assess compliance of such equipmentand pipelines with hazardous liquid pipeline safety requirements. To the extent that these actions are pursued by PHMSA, midstream operators of NGLfractionation facilities and associated storage facilities subject to such inspection may be required to make operational changes or modifications at theirfacilities to meet standards beyond current PSM and RMP requirements, which changes or modifications may result in additional capital costs, possibleoperational delays and increased costs of operation that, in some instances, may be significant.Environmental MattersGeneral. Our operation of processing plants, pipelines and associated facilities, including compression, in connection with the gathering, processing, storageand transmission of natural gas and the storage and transportation of NGLs, crude oil and refined products is subject to stringent federal, tribal, state and locallaws and regulations, including those governing, among other things, air emissions, wastewater discharges, the use, management and disposal of hazardousand nonhazardous materials and wastes, and the cleanup of contamination. Noncompliance with such laws and regulations, or incidents resulting inenvironmental releases, could cause us to incur substantial costs, penalties, fines and criminal sanctions, third-party claims for personal injury or propertydamage, capital expenditures to retrofit or upgrade our facilities and programs, or curtailment or cancellation of permits on operations. As with the industrygenerally, compliance with existing and anticipated environmental laws and regulations increases our overall cost of doing business, including our cost ofplanning, permitting, constructing and operating our plants, pipelines and other facilities. As a result of these laws and regulations, our construction andoperation costs include capital, operating and maintenance cost items necessary to maintain or upgrade our equipment and facilities.24 Table of ContentsWe have implemented procedures designed to ensure that governmental environmental approvals for both existing operations and those under constructionare updated as circumstances require. Historically, our environmental compliance costs have not had a material adverse effect on our business, results ofoperations or financial condition; however, there can be no assurance that such costs will not be material in the future. For example, we cannot be certain,however, that identification of presently unidentified conditions, more rigorous enforcement by regulatory agencies, enactment of more stringentenvironmental laws and regulations or unanticipated events will not arise in the future and give rise to environmental liabilities that could have a materialadverse effect on our business, financial condition or results of operations.Hazardous Substances and Waste Materials. To a large extent, the environmental laws and regulations affecting our operations relate to the release ofhazardous substances and waste materials into soils, groundwater and surface water and include measures to prevent, minimize or remediate contamination ofthe environment. These laws and regulations generally regulate the generation, storage, treatment, transportation and disposal of hazardous substances andwaste materials and may require investigatory and remedial actions at sites where such material has been released or disposed. For example, theComprehensive Environmental Response, Compensation and Liability Act, as amended, (“CERCLA”), also known as the “Superfund” law, and comparablestate laws, impose liability without regard to fault or the legality of the original conduct on certain classes of persons that contributed to a release of a“hazardous substance” into the environment. These persons include the owner and operator of the site where a release occurred and companies that disposedor arranged for the disposal of the hazardous substance that has been released into the environment. Under CERCLA, these persons may be subject to strict,joint and several liability, without regard to fault, for, among other things, the costs of investigating and remediating the hazardous substances that have beenreleased into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA and comparable state law also authorizethe federal EPA, its state counterparts, and, in some instances, third parties to take actions in response to threats to the public health or the environment and toseek to recover from the responsible classes of persons the costs they incur. It is not uncommon for neighboring landowners and other third parties to fileclaims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. Although“petroleum” as well as natural gas and NGLs are excluded from CERCLA’s definition of a “hazardous substance,” in the course of our ordinary operations wegenerate wastes that may fall within that definition or that may be subject to other waste disposal laws and regulations. We may be responsible underCERCLA or state laws for all or part of the costs required to clean up sites at which such substances or wastes have been disposed.We also generate both hazardous and nonhazardous wastes that are subject to requirements of the federal Resource Conservation and Recovery Act, asamended, (“RCRA”) and comparable state statutes. We are not currently required to comply with a substantial portion of the RCRA hazardous wasterequirements at many of our facilities because the minimal quantities of hazardous wastes generated there make us subject to less stringent non-hazardousmanagement standards. From time to time, the EPA has considered or third parties have petitioned the agency on the adoption of stricter handling, storageand disposal standards for nonhazardous wastes, including certain wastes associated with the exploration, development and production of crude oil andnatural gas. For example, following the filing of a lawsuit by several non-governmental environmental groups against the EPA for the agency’s failure totimely assess its RCRA Subtitle D criteria regulations for oil and gas wastes, EPA and the environmental groups entered into an agreement that was finalizedin a consent decree issued by the United States District Court for the District of Columbia on December 28, 2016. Under the decree, the EPA is required topropose no later than March 15, 2019, a rulemaking for revision of certain Subtitle D criteria regulations pertaining to oil and gas wastes or sign adetermination that revision of the regulations is not necessary. If EPA proposes a rulemaking for revised oil and gas waste regulations, the Consent Decreerequires that the EPA take final action following notice and comment rulemaking no later than July 15, 2021. It is possible that some wastes generated by usthat are currently classified as nonhazardous may in the future be designated as “hazardous wastes,” resulting in the wastes being subject to more rigorousand costly disposal requirements, or that the full complement of RCRA standards could be applied to facilities that generate lesser amounts of hazardouswaste. Changes such as these examples in applicable regulations may result in a material increase in our capital expenditures or plant operating andmaintenance expense and, in the case of our oil and natural gas exploration and production customers, could result in increased operating costs for thosecustomers and a corresponding decrease in demand for our processing, transportation and storage services.We currently own or lease sites that have been used over the years by prior owners and lessees and by us for various activities related to gathering, processing,storage and transmission of natural gas, NGLs, crude oil and products. Waste disposal practices within the oil and gas industry have improved over the yearswith the passage and implementation of various environmental laws and regulations. Nevertheless, some hydrocarbons and wastes have been disposed of orotherwise released on or under various sites during the operating history of those facilities that are now owned or leased by us. Notwithstanding thepossibility that these releases may have occurred during the ownership or operation of these assets by others, these sites may be subject to CERCLA, RCRAand comparable state laws. Under these laws, we could be required to remove or remediate previously disposed wastes (including wastes disposed of orreleased by prior owners or operators) or contamination (including soil and groundwater contamination) or to prevent the migration of contamination.25 Table of ContentsAs of December 31, 2017 and 2016, accruals of $350 million and $309 million, respectively, were recorded in our consolidated balance sheets as accrued andother current liabilities and other non-current liabilities to cover estimated material environmental liabilities including, for example, certain matters assumedin connection with our acquisition of the HPL System, our acquisition of Transwestern, potential environmental liabilities for three sites that were formerlyowned by Titan Energy Partners, L.P. or its predecessors, and the predecessor owner’s share of certain environmental liabilities of ETC OLP.The Partnership is subject to extensive and frequently changing federal, tribal, state and local laws and regulations, including those relating to the dischargeof materials into the environment or that otherwise relate to the protection of the environment, waste management and the characteristics and composition offuels. These laws and regulations require environmental assessment and remediation efforts at many of Sunoco, Inc.’s facilities and at formerly owned orthird-party sites. Accruals for these environmental remediation activities amounted to $284 million and $289 million at December 31, 2017 and 2016,respectively, which is included in the total accruals above. These legacy sites that are subject to environmental assessments include formerly owned terminalsand other logistics assets, retail sites that are no longer operated by Sunoco, Inc., closed and/or sold refineries and other formerly owned sites. In December2013, a wholly-owned captive insurance company was established for these legacy sites that are no longer operating. The premiums paid to the captiveinsurance company include estimates for environmental claims that have been incurred but not reported, based on an actuarially determined fully developedclaims expense estimate. In such cases, we accrue losses attributable to unasserted claims based on the discounted estimates that are used to develop thepremiums paid to the captive insurance company. As of December 31, 2017 the captive insurance company held $207 million of cash and investments.The Partnership’s accrual for environmental remediation activities reflects anticipated work at identified sites where an assessment has indicated that cleanupcosts are probable and reasonably estimable. The accrual for known claims is undiscounted and is based on currently available information, estimated timingof remedial actions and related inflation assumptions, existing technology and presently enacted laws and regulations. It is often extremely difficult todevelop reasonable estimates of future site remediation costs due to changing regulations, changing technologies and their associated costs, and changes inthe economic environment. Engineering studies, historical experience and other factors are used to identify and evaluate remediation alternatives and theirrelated costs in determining the estimated accruals for environmental remediation activities.Under various environmental laws, including the RCRA, the Partnership has initiated corrective remedial action at certain of its facilities, formerly ownedfacilities and at certain third-party sites. At the Partnership’s major manufacturing facilities, we have typically assumed continued industrial use and acontainment/remediation strategy focused on eliminating unacceptable risks to human health or the environment. The remediation accruals for these sitesreflect that strategy. Accruals include amounts designed to prevent or mitigate off-site migration and to contain the impact on the facility property, as well asto address known, discrete areas requiring remediation within the plants. Remedial activities include, for example, closure of RCRA waste management units,recovery of hydrocarbons, handling of impacted soil, mitigation of surface water impacts and prevention or mitigation of off-site migration. A change in thisapproach as a result of changing the intended use of a property or a sale to a third party could result in a comparatively higher cost remediation strategy in thefuture.In general, a remediation site or issue is typically evaluated on an individual basis based upon information available for the site or issue and no pooling orstatistical analysis is used to evaluate an aggregate risk for a group of similar items (for example, service station sites) in determining the amount of probableloss accrual to be recorded. The estimates of environmental remediation costs also frequently involve evaluation of a range of estimates. In many cases, it isdifficult to determine that one point in the range of loss estimates is more likely than any other. In these situations, existing accounting guidance allows usthe minimum amount of the range to accrue. Accordingly, the low end of the range often represents the amount of loss which has been recorded.In addition to the probable and estimable losses which have been recorded, management believes it is reasonably possible (that is, it is less than probable butgreater than remote) that additional environmental remediation losses will be incurred. At December 31, 2017, the aggregate of such additional estimatedmaximum reasonably possible losses, which relate to numerous individual sites, totaled approximately $5 million, which amount is in excess of the $350million in environmental accruals recorded on December 31, 2017. This estimate of reasonably possible losses comprises estimates for remediation activitiesat current logistics and retail assets, and in many cases, reflects the upper end of the loss ranges which are described above. Such estimates include potentiallyhigher contractor costs for expected remediation activities, the potential need to use more costly or comprehensive remediation methods and longeroperating and monitoring periods, among other things.In summary, total future costs for environmental remediation activities will depend upon, among other things, the identification of any additional sites, thedetermination of the extent of the contamination at each site, the timing and nature of required remedial actions, the nature of operations at each site, thetechnology available and needed to meet the various existing legal requirements, the nature and terms of cost-sharing arrangements with other potentiallyresponsible parties, the availability of insurance coverage, the nature and extent of future environmental laws and regulations, inflation rates, terms ofconsent agreements or remediation permits with regulatory agencies and the determination of the Partnership’s liability at the sites, if any, in light of thenumber, participation level and financial viability of the other parties. The recognition of additional losses, if and when they were to occur,26 Table of Contentswould likely extend over many years, but management can provide no assurance that it would be over many years. If changes in environmental laws orregulations occur or the assumptions used to estimate losses at multiple sites are adjusted, such changes could materially and adversely impact multiplefacilities, formerly owned facilities and third-party sites at the same time. As a result, from time to time, significant charges against income for environmentalremediation may occur. And while management does not believe that any such charges would have a material adverse impact on the Partnership’sconsolidated financial position, it can provide no assurance.Transwestern conducts soil and groundwater remediation at a number of its facilities. Some of the cleanup activities include remediation of severalcompressor sites on the Transwestern system for contamination by PCBs, and the costs of this work are not eligible for recovery in rates. The total accruedfuture estimated cost of remediation activities expected to continue through 2025 is $5 million, which is included in the total environmental accrualsmentioned above. Transwestern received FERC approval for rate recovery of projected soil and groundwater remediation costs not related to PCBs effectiveApril 1, 2007. Transwestern, as part of ongoing arrangements with customers, continues to incur costs associated with containing and removing potentialPCB contamination. Future costs cannot be reasonably estimated because remediation activities are undertaken as potential claims are made by customersand former customers. Such future costs are not expected to have a material impact on our financial position, results of operations or cash flows, butmanagement can provide no assurance.Air Emissions. Our operations are subject to the federal Clean Air Act, as amended, and comparable state laws and regulations. These laws and regulationsregulate emissions of air pollutants from various industrial sources, including our processing plants, and also impose various monitoring and reportingrequirements. Such laws and regulations may require that we obtain pre-approval for the construction or modification of certain projects or facilities, such asour processing plants and compression facilities, expected to produce air emissions or to result in the increase of existing air emissions, that we obtain andstrictly comply with air permits containing various emissions and operational limitations, or that we utilize specific emission control technologies to limitemissions. We will incur capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operatingpermits and approvals for air emissions. In addition, our processing plants, pipelines and compression facilities are subject to increasingly stringentregulations, including regulations that require the installation of control technology or the implementation of work practices to control hazardous airpollutants. Moreover, the Clean Air Act requires an operating permit for major sources of emissions and this requirement applies to some of our facilities.Historically, our costs for compliance with existing Clean Air Act and comparable state law requirements have not had a material adverse effect on our resultsof operations; however, there can be no assurance that such costs will not be material in the future. The EPA and state agencies are often considering,proposing or finalizing new regulations that could impact our existing operations and the costs and timing of new infrastructure development. For example,in October 2015, the EPA published a final rule under the Clean Air Act, lowering the National Ambient Air Quality Standard (“NAAQS”) for ground-levelozone to 70 parts per billion for the 8-hour primary and secondary ozone standards. The EPA published a final rule in November 2017 that issued areadesignations with respect to ground-level ozone for approximately 85% of the United States counties as either “attainment/unclassifiable” or “unclassifiable”and is expected to issue non-attainment designations for the remaining areas of the United States not addressed under the November 2017 final rule in thefirst half of 2018. Reclassification of areas or imposition of more stringent standards may make it more difficult to construct new or modified sources of airpollution in newly designated non-attainment areas. Also, states are expected to implement more stringent requirements as a result of this new final rule,which could apply to our customers’ operations. Compliance with this or other new regulations could, among other things, require installation of newemission controls on some of our equipment, result in longer permitting timelines, and significantly increase our capital expenditures and operating costs,which could adversely impact our business.Clean Water Act. The Federal Water Pollution Control Act of 1972, as amended, (“Clean Water Act”) and comparable state laws impose restrictions and strictcontrols regarding the discharge of pollutants, including hydrocarbon-bearing wastes, into state waters and waters of the United States. Pursuant to the CleanWater Act and similar state laws, a National Pollutant Discharge Elimination System, or state permit, or both, must be obtained to discharge pollutants intofederal and state waters. In addition, the Clean Water Act and comparable state laws require that individual permits or coverage under general permits beobtained by subject facilities for discharges of storm water runoff. The Clean Water Act also prohibits the discharge of dredge and fill material in regulatedwaters, including wetlands, unless authorized by permit. In May 2015, the EPA issued a final rule that attempts to clarify the federal jurisdictional reach overwaters of the United States but this rule has been stayed nationwide by the United States Sixth Circuit Court of Appeals as that appellate court and numerousdistrict courts ponder lawsuits opposing implementation of the rule. In June 2015, the EPA and the United States Army Corps of Engineers (the “Corps”)published a final rule attempting to clarify the federal jurisdictional reach over waters of the United States, but legal challenges to this rule followed. The2015 rule was stayed nationwide to determine whether federal district or appellate courts had jurisdiction to hear cases in the matter and, in January 2017, theUnited States Supreme Court agreed to hear the case. The EPA and Corps proposed a rulemaking in June 2017 to repeal the June 2015 rule, announced theirintent to issue a new rule defining the Clean Water Act’s jurisdiction, and published a proposed rule in November 2017 specifying that the contested May2015 rule would not take effect until two years after the November 2017 proposed rule was finalized and published in the Federal Register. Recently, onJanuary 22, 2018, the27 Table of ContentsUnited States Supreme Court issued a decision finding that jurisdiction resides with the federal district courts; consequently, while implementation of the2015 rule currently remains stayed, the previously-filed district court cases will be allowed to proceed. On January 31, 2018, the EPA and Corps finalized arule that would delay applicability of the rule to two years from the rule’s publication in the Federal Register. As a result of these recent developments, futureimplementation of the June 2015 rule is uncertain at this time but to the extent any rule expands the scope of the Clean Water Act’s jurisdiction, ouroperations as well as our exploration and production customers’ drilling programs could incur increased costs and delays with respect to obtaining permitsfor dredge and fill activities in wetland areas.Spills. Our operations can result in the discharge of regulated substances, including NGLs, crude oil or other products. The Clean Water Act, as amended bythe federal Oil Pollution Act of 1990, as amended, (“OPA”), and comparable state laws impose restrictions and strict controls regarding the discharge ofregulated substances into state waters or waters of the United States. The Clean Water Act and comparable state laws can impose substantial administrative,civil and criminal penalties for non-compliance including spills and other non-authorized discharges. The OPA subjects owners of covered facilities to strictjoint and potentially unlimited liability for removal costs and other consequences of a release of oil, where the release is into navigable waters, alongshorelines or in the exclusive economic zone of the United States. Spill prevention control and countermeasure requirements of the Clean Water Act andsome state laws require that containment dikes and similar structures be installed to help prevent the impact on navigable waters in the event of a release ofoil. The PHMSA, the EPA, or various state regulatory agencies, has approved our oil spill emergency response plans that are to be used in the event of a spillincident.In addition, some states maintain groundwater protection programs that require permits for discharges or operations that may impact groundwater conditions.Our management believes that compliance with existing permits and compliance with foreseeable new permit requirements will not have a material adverseeffect on our results of operations, financial position or expected cash flows.Endangered Species Act. The Endangered Species Act, as amended, restricts activities that may affect endangered or threatened species or their habitat.Similar protections are offered to migratory birds under the Migratory Bird Treaty Act. We may operate in areas that are currently designated as a habitat forendangered or threatened species or where the discovery of previously unidentified endangered species, or the designation of additional species asendangered or threatened may occur in which event such one or more developments could cause us to incur additional costs, to develop habitat conservationplans, to become subject to expansion or operating restrictions, or bans in the affected areas. Moreover, such designation of previously unprotected species asthreatened or endangered in areas where our oil and natural gas exploration and production customers operate could cause our customers to incur increasedcosts arising from species protection measures and could result in delays or limitations in our customers’ performance of operations, which could reducedemand for our services.Climate Change. Climate change continues to attract considerable public, governmental and scientific attention. As a result, numerous proposals have beenmade and are likely to continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of GHGs.These efforts have included consideration of cap-and-trade programs, carbon taxes and GHG reporting and tracking programs, and regulations that directlylimit GHG emissions from certain sources. At the federal level, no comprehensive climate change legislation has been implemented to date. The EPA has,however, adopted rules under authority of the Clean Air Act that, among other things, establish Potential for Significant Deterioration (“PSD”) constructionand Title V operating permit reviews for GHG emissions from certain large stationary sources that are also potential major sources of certain principal, orcriteria, pollutant emissions, which reviews could require securing PSD permits at covered facilities emitting GHGs and meeting “best available controltechnology” standards for those GHG emissions. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissionsfrom certain petroleum and natural gas system sources in the United States, including, among others, onshore processing, transmission, storage anddistribution facilities. In October 2015, the EPA amended and expanded the GHG reporting requirements to all segments of the oil and natural gas industry,including gathering and boosting facilities and blowdowns of natural gas transmission pipelines.Federal agencies also have begun directly regulating emissions of methane, a GHG, from oil and natural gas operations. In June 2016, the EPA published NewSource Performance Standards (“NSPS”), known as Subpart OOOOa, that require certain new, modified or reconstructed facilities in the oil and natural gassector to reduce these methane gas and volatile organic compound emissions. These Subpart OOOOa standards will expand previously issued NSPSpublished by the EPA in 2012 and known as Subpart OOOO, by using certain equipment-specific emissions control practices, requiring additional controlsfor pneumatic controllers and pumps as well as compressors, and imposing leak detection and repair requirements for natural gas compressor and boosterstations. However, the Subpart OOOOa standards have been subject to attempts by the EPA to stay portions of those standards, and the agency proposedrulemaking in June 2017 to stay the requirements for a period of two years and revisit implementation of Subpart OOOOa in its entirety. The EPA has not yetpublished a final rule and, as a result, the June 2016 rule remains in effect but future implementation of the 2016 standards is uncertain at this time. This rule,should it remain in effect, and any other new methane emission standards imposed on the oil and gas sector could result in increased costs to our operationsas well as result in delays or curtailment in such operations, which costs, delays or curtailment could adversely affect our business.28 Table of ContentsAdditionally, in December 2015, the United States joined the international community at the 21st Conference of the Parties of the United Nations FrameworkConvention on Climate Change in Paris, France preparing an agreement requiring member countries to review and “represent a progression” in their intendednationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This “Paris Agreement” was signed by theUnited States in April 2016 and entered into force in November 2016; however, this agreement does not create any binding obligations for nations to limittheir GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In August 2017, the United States State Department informedthe United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four-year exit processbeginning when it took effect in November 2016, which would result in an effective exit date of November 2020. The United States’ adherence to the exitprocess and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time.The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHGs or otherwise restrictemissions of GHGs could result in increased compliance costs or additional operating restrictions, and could have a material adverse effect on our business,financial condition, demand for our services, results of operations, and cash flows. Recently, activists concerned about the potential effects of climate changehave directed their attention at sources of funding for fossil-fuel energy companies, which has resulted in certain financial institutions, funds and othersources of capital restricting or eliminating their investment in oil and natural gas activities. Ultimately, this could make it more difficult to secure fundingfor exploration and production or midstream activities. Notwithstanding potential risks related to climate change, the International Energy Agency estimatesthat global energy demand will continue to rise and will not peak until after 2040 and that oil and natural gas will continue to represent a substantialpercentage of global energy use over that time. Finally, some scientists have concluded that increasing concentrations of GHG in the atmosphere mayproduce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climateevents that could have an adverse effect on our assets.Some have suggested that one consequence of climate change could be increased severity of extreme weather, such as increased hurricanes and floods. If sucheffects were to occur, our operations could be adversely affected in various ways, including damages to our facilities from powerful winds or rising waters, orincreased costs for insurance. Another possible consequence of climate change is increased volatility in seasonal temperatures. The market for our NGLs andnatural gas is generally improved by periods of colder weather and impaired by periods of warmer weather, so any changes in climate could affect the marketfor the fuels that we produce. Despite the use of the term “global warming” as a shorthand for climate change, some studies indicate that climate change couldcause some areas to experience temperatures substantially colder than their historical averages. As a result, it is difficult to predict how the market for ourproducts could be affected by increased temperature volatility, although if there is an overall trend of warmer temperatures, it would be expected to have anadverse effect on our business.Employee Health and Safety. We are subject to the requirements of the federal OSHA and comparable state laws that regulate the protection of the health andsafety of workers. In addition, the Occupational Safety and Health Administration’s hazard communication standard requires that information be maintainedabout hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities andcitizens. Historically, our costs for OSHA required activities, including general industry standards, recordkeeping requirements, and monitoring ofoccupational exposure to regulated substances, have not had a material adverse effect on our results of operations but there is no assurance that such costswill not be material in the future.EmployeesAs of December 31, 2017, we employed 8,494 persons, 1,225 of which are represented by labor unions. We believe that our relations with our employees aresatisfactory.SEC ReportingWe file or furnish annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any related amendments and supplementsthereto with the SEC.

RISK FACTORSIn addition to risks and uncertainties in the ordinary course of business that are common to all businesses, important factors that are specific to our structureas a limited partnership, our industry and our company could materially impact our future performance and results of operations. We have provided below alist of these risk factors that should be reviewed when considering an investment in our securities. Panhandle files Annual Reports on Form 10-K that includerisk factors that can be reviewed for further information. The risk factors set forth below, and those included in Panhandle’s Annual Report on Form 10-K, arenot all the risks we face and other factors currently considered immaterial or unknown to us may impact our future operations.Risks Inherent in an Investment in UsCash distributions are not guaranteed and may fluctuate with our performance and other external factors.The amount of cash we can distribute to holders of our Common Units or other partnership securities depends upon the amount of cash we generate from ouroperations. The amount of cash we generate from our operations will fluctuate from quarter to quarter and will depend upon, among other things:•the amount of natural gas, NGLs, crude oil and refined products transported in our pipelines and gathering systems;•the level of throughput in our processing and treating operations;•the fees we charge and the margins we realize for our services;•the price of natural gas, NGLs, crude oil and refined products;•the relationship between natural gas, NGL and crude oil prices;•the amount of cash distributions we receive with respect to the Sunoco LP common units that our subsidiaries own;•the weather in our operating areas;•the level of competition from other midstream, transportation and storage and other energy providers;•the level of our operating costs;•prevailing economic conditions; and•the level and results of our derivative activities.In addition, the actual amount of cash we will have available for distribution will also depend on other factors, such as:•the level of capital expenditures we make;•the level of costs related to litigation and regulatory compliance matters;•the cost of acquisitions, if any;•the levels of any margin calls that result from changes in commodity prices;•our debt service requirements;•fluctuations in our working capital needs;•our ability to borrow under our revolving credit facility;•our ability to access capital markets;•restrictions on distributions contained in our debt agreements; and•the amount of cash reserves established by our General Partner in its discretion for the proper conduct of our business.Because of all these factors, we cannot guarantee that we will have sufficient available cash to pay a specific level of cash distributions to our Unitholders.Furthermore, Unitholders should be aware that the amount of cash we have available for distribution depends primarily upon our cash flow and is not solely afunction of profitability, which is affected by non-cash items. As a result, we may declare and/or pay cash distributions during periods when we record netlosses.30 Table of ContentsWe may sell additional limited partner interests or other classes of equity, diluting existing interests of Unitholders.Our partnership agreement allows us to issue an unlimited number of additional limited partner interests, including securities senior to the Common Units,without the approval of our Unitholders. The issuance of additional Common Units or other equity securities will have the following effects:•the current proportionate ownership interest of our Unitholders in us will decrease;•the amount of cash available for distribution on each Common Unit or partnership security may decrease;•the ratio of taxable income to distributions may increase;•the relative voting strength of each previously outstanding Common Unit may be diminished; and•the market price of the Common Units or partnership securities may decline.Sunoco LP may issue additional common units, which may increase the risk that Sunoco LP will not have sufficient available cash to maintain or increaseits per unit distribution level.Sunoco LP’s partnership agreement allows the issuance of an unlimited number of additional limited partner interests. The issuance of additional commonunits or other equity securities by Sunoco LP will have the following effects:•Unitholders’ current proportionate ownership interest in Sunoco LP will decrease;•the amount of cash available for distribution on each common unit or partnership security may decrease;•the ratio of taxable income to distributions may increase;•the relative voting strength of each previously outstanding common unit may be diminished; and•the market price of Sunoco LP common units may decline.The payment of distributions on any additional units issued by Sunoco LP may increase the risk that it may not have sufficient cash available to maintain orincrease its per unit distribution level, which in turn may impact the available cash that we have to meet our obligations.Future sales of our units or other limited partner interests in the public market could reduce the market price of Unitholders’ limited partner interests.As of January 31, 2018, ETE owned 27.5 million ETP Common Units. If ETE were to sell and/or distribute its Common Units to the holders of its equityinterests in the future, those holders may dispose of some or all of these units. The sale or disposition of a substantial portion of these units in the publicmarkets could reduce the market price of our outstanding Common Units.Unitholders may not have limited liability if a court finds that Unitholder actions constitute control of our business.Under Delaware law, a Unitholder could be held liable for our obligations to the same extent as a general partner if a court determined that the right ofUnitholders to remove our general partner or to take other action under our partnership agreement constituted participation in the “control” of our business.Our general partner generally has unlimited liability for our obligations, such as our debts and environmental liabilities, except for those contractualobligations that are expressly made without recourse to our general partner. Our partnership agreement allows the general partner to incur obligations on ourbehalf that are expressly non-recourse to the general partner. The general partner has entered into such limited recourse obligations in most instancesinvolving payment liability and intends to do so in the future.In addition, Section 17-607 of the Delaware Revised Uniform Limited Partnership Act provides that under some circumstances, a Unitholder may be liable tous for the amount of a distribution for a period of three years from the date of the distribution.Our debt level and debt agreements may limit our ability to make distributions to Unitholders and may limit our future financial and operating flexibility.As of December 31, 2017, we had approximately $33.09 billion of consolidated debt, excluding the debt of our joint ventures. Our level of indebtednessaffects our operations in several ways, including, among other things:•a significant portion of our and our subsidiaries’ cash flow from operations will be dedicated to the payment of principal and interest on outstanding debtand will not be available for other purposes, including payment of distributions;•covenants contained in our and our subsidiaries’ existing debt agreements require us and them, as applicable, to meet financial tests that may adverselyaffect our flexibility in planning for and reacting to changes in our business;31 Table of Contents•our and our subsidiaries’ ability to obtain additional financing for working capital, capital expenditures, acquisitions and general partnership, corporateor limited liability company purposes, as applicable, may be limited;•we may be at a competitive disadvantage relative to similar companies that have less debt;•we may be more vulnerable to adverse economic and industry conditions as a result of our significant debt level; and•failure by us or our subsidiaries to comply with the various restrictive covenants of our respective debt agreements could negatively impact our ability toincur additional debt, including our ability to utilize the available capacity under our revolving credit facility, and our ability to pay our distributions.Capital projects will require significant amounts of debt and equity financing, which may not be available to us on acceptable terms, or at all.We plan to fund our growth capital expenditures, including any new pipeline construction projects and improvements or repairs to existing facilities that wemay undertake, with proceeds from sales of our debt and equity securities and borrowings under our revolving credit facility; however, we cannot be certainthat we will be able to issue our debt and equity securities on terms satisfactory to us, or at all. If we are unable to finance our expansion projects as expected,we could be required to seek alternative financing, the terms of which may not be attractive to us, or to revise or cancel our expansion plans.A significant increase in our indebtedness that is proportionately greater than our issuance of equity could negatively impact our and our subsidiaries’ creditratings or our ability to remain in compliance with the financial covenants under our revolving credit agreement, which could have a material adverse effecton our financial condition, results of operations and cash flows.Increases in interest rates could adversely affect our business, results of operations, cash flows and financial condition.In addition to our exposure to commodity prices, we have exposure to changes in interest rates. Approximately $5.11 billion of our consolidated debt as ofDecember 31, 2017 bears interest at variable interest rates and the remainder bears interest at fixed rates. To the extent that we have debt with floating interestrates, our results of operations, cash flows and financial condition could be materially adversely affected by increases in interest rates. We manage a portionof our interest rate exposures by utilizing interest rate swaps.An increase in interest rates may also cause a corresponding decline in demand for equity investments, in general, and in particular for yield-based equityinvestments such as our Common Units. Any such reduction in demand for our Common Units resulting from other more attractive investment opportunitiesmay cause the trading price of our Common Units to decline.The credit and risk profile of our General Partner and its owners could adversely affect our credit ratings and profile.The credit and business risk profiles of our General Partner, and of ETE as the indirect owner of our General Partner, may be factors in credit evaluations of usas a publicly traded limited partnership due to the significant influence of our General Partner and ETE over our business activities, including our cashdistributions, acquisition strategy and business risk profile. Another factor that may be considered is the financial condition of our General Partner and itsowners, including the degree of their financial leverage and their dependence on cash flow from the Partnership to service their indebtedness.ETE has significant indebtedness outstanding and is dependent principally on the cash distributions from its general and limited partner equity interests in usto service such indebtedness. Any distributions by us to ETE will be made only after satisfying our then current obligations to our creditors. Although wehave taken certain steps in our organizational structure, financial reporting and contractual relationships to reflect the separateness of us, ETP GP and ETPLLC from the entities that control ETP GP (ETE and its general partner), our credit ratings and business risk profile could be adversely affected if the ratingsand risk profiles of such entities were viewed as substantially lower or riskier than ours.Unitholders have limited voting rights and are not entitled to elect the General Partner or its directors. In addition, even if Unitholders are dissatisfied,they cannot easily remove the General Partner.Unlike the holders of common stock in a corporation, Unitholders have only limited voting rights on matters affecting our business, and therefore limitedability to influence management’s decisions regarding our business. Unitholders did not elect our General Partner and will have no right to elect our GeneralPartner on an annual or other continuing basis. Although our General Partner has a contractually-limited fiduciary duty to our Unitholders, the directors ofour General Partner and its general partner have a fiduciary duty to manage the General Partner and its general partner in a manner beneficial to the owners ofthose entities.Furthermore, if the Unitholders are dissatisfied with the performance of our General Partner, they may be unable to remove our General Partner. The GeneralPartner generally may not be removed except upon the vote of the holders of 66 2/3% of the outstanding units voting together as a single class, includingunits owned by the General Partner and its affiliates. As of December 31, 2017,32 Table of ContentsETE and its affiliates held approximately 2.4% of our outstanding Common Units and our officers and directors held less than 1% of our outstandingCommon Units.Furthermore, Unitholders’ voting rights are further restricted by the partnership agreement provision providing that any units held by a person that owns 20%or more of any class of units then outstanding, other than the General Partner and its affiliates, cannot be voted on any matter.Our General Partner may, in its sole discretion, approve the issuance of partnership securities and specify the terms of such partnership securities.Pursuant to our partnership agreement, our General Partner has the ability, in its sole discretion and without the approval of the Unitholders, to approve theissuance of securities by the Partnership at any time and to specify the terms and conditions of such securities. The securities authorized to be issued may beissued in one or more classes or series, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series ofpartnership securities), as shall be determined by our General Partner, including:•the right to share in the Partnership’s profits and losses;•the right to share in the Partnership’s distributions;•the rights upon dissolution and liquidation of the Partnership;•whether, and the terms upon which, the Partnership may redeem the securities;•whether the securities will be issued, evidenced by certificates and assigned or transferred; and•the right, if any, of the security to vote on matters relating to the Partnership, including matters relating to the relative rights, preferences and privilegesof such security.Please see “We may sell additional limited partner interests, diluting existing interests of Unitholders.” above.The control of our General Partner may be transferred to a third party without Unitholder consent.The General Partner may transfer its general partner interest to a third party without the consent of the Unitholders. Furthermore, the general partner of ourGeneral Partner may transfer its general partner interest in our General Partner to a third party without the consent of the Unitholders. Any new owner of theGeneral Partner or the general partner of the General Partner would be in a position to replace the officers of the General Partner with its own choices and tocontrol the decisions taken by such officers.Unitholders may be required to sell their units to the General Partner at an undesirable time or price.If at any time less than 20% of the outstanding units of any class are held by persons other than the General Partner and its affiliates, the General Partner willhave the right to acquire all, but not less than all, of those units at a price no less than their then-current market price. As a consequence, a Unitholder may berequired to sell their Common Units at an undesirable time or price. The General Partner may assign this purchase right to any of its affiliates or to us.The interruption of distributions to us from our operating subsidiaries and equity investees may affect our ability to satisfy our obligations and to makedistributions to our partners.We are a holding company with no business operations other than that of our operating subsidiaries. Our only significant assets are the equity interests weown in our operating subsidiaries and equity investees. As a result, we depend upon the earnings and cash flow of our operating subsidiaries and equityinvestees and any interruption of distributions to us may affect our ability to meet our obligations, including any obligations under our debt agreements, andto make distributions to our partners.Cost reimbursements due to our General Partner may be substantial and may reduce our ability to pay the distributions to Unitholders.Prior to making any distributions to our Unitholders, we will reimburse our General Partner for all expenses it has incurred on our behalf. In addition, ourGeneral Partner and its affiliates may provide us with services for which we will be charged reasonable fees as determined by the General Partner. Thereimbursement of these expenses and the payment of these fees could adversely affect our ability to make distributions to the Unitholders. Our GeneralPartner has sole discretion to determine the amount of these expenses and fees.33 Table of ContentsUnitholders may have liability to repay distributions.Under certain circumstances, Unitholders may have to repay us amounts wrongfully distributed to them. Under Delaware law, we may not make a distributionto Unitholders if the distribution causes our liabilities to exceed the fair value of our assets. Liabilities to partners on account of their partnership interests andnon-recourse liabilities are not counted for purposes of determining whether a distribution is permitted. Delaware law provides that a limited partner whoreceives such a distribution and knew at the time of the distribution that the distribution violated Delaware law, will be liable to the limited partnership forthe distribution amount for three years from the distribution date. Under Delaware law, an assignee who becomes a substituted limited partner of a limitedpartnership is liable for the obligations of the assignor to make contributions to the partnership. However, such an assignee is not obligated for liabilitiesunknown to him at the time he or she became a limited partner if the liabilities could not be determined from the partnership agreement.We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets.We are a holding company, and our subsidiaries conduct all of our operations and own all of our operating assets. We do not have significant assets otherthan the partnership interests and the equity in our subsidiaries. As a result, our ability to pay distributions to our Unitholders and to service our debt dependson the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restrictedby, among other things, credit facilities and applicable state partnership laws and other laws and regulations. If we are unable to obtain funds from oursubsidiaries we may not be able to pay distributions to our Unitholders or to pay interest or principal on our debt when due.We do not have the same flexibility as other types of organizations to accumulate cash, which may limit cash available to service our debt or to repay debtat maturity.Unlike a corporation, our partnership agreement requires us to distribute, on a quarterly basis, 100% of our Available Cash (as defined in our partnershipagreement) to our Unitholders of record and our General Partner. Available Cash is generally all of our cash on hand as of the end of a quarter, adjusted forcash distributions and net changes to reserves. Our General Partner will determine the amount and timing of such distributions and has broad discretion toestablish and make additions to our reserves or the reserves of our operating subsidiaries in amounts it determines in its reasonable discretion to be necessaryor appropriate:•to provide for the proper conduct of our business and the businesses of our operating subsidiaries (including reserves for future capital expenditures andfor our anticipated future credit needs);•to provide funds for distributions to our Unitholders and our General Partner for any one or more of the next four calendar quarters; or•to comply with applicable law or any of our loan or other agreements.A downgrade of our credit ratings could impact our and our subsidiaries’ liquidity, access to capital and costs of doing business, and maintaining creditratings is under the control of independent third parties.A downgrade of our credit ratings might increase our and our subsidiaries’ cost of borrowing and could require us to post collateral with third parties,negatively impacting our available liquidity. Our and our subsidiaries’ ability to access capital markets could also be limited by a downgrade of our creditratings and other disruptions. Such disruptions could include:•economic downturns;•deteriorating capital market conditions;•declining market prices for natural gas, NGLs and other commodities;•terrorist attacks or threatened attacks on our facilities or those of other energy companies; and•the overall health of the energy industry, including the bankruptcy or insolvency of other companies.Credit rating agencies perform independent analysis when assigning credit ratings. The analysis includes a number of criteria including, but not limited to,business composition, market and operational risks, as well as various financial tests. Credit rating agencies continue to review the criteria for industry sectorsand various debt ratings and may make changes to those criteria from time to time. Credit ratings are not recommendations to buy, sell or hold investments inthe rated entity. Ratings are subject to revision or withdrawal at any time by the rating agencies, and we cannot assure you that we will maintain our currentcredit ratings.34 Table of ContentsRisks Related to Conflicts of InterestOur partnership agreement limits our General Partner’s fiduciary duties to our Unitholders and restricts the remedies available to Unitholders for actionstaken by our General Partner that might otherwise constitute breaches of fiduciary duty.Our partnership agreement contains provisions that waive or consent to conduct by our General Partner and its affiliates and reduce the obligations to whichour General Partner would otherwise be held by state-law fiduciary duty standards. The following is a summary of the material restrictions contained in ourpartnership agreement on the duties owed by our General Partner, and our officers and directors, to the limited partners. Our partnership agreement:•eliminates all standards of care and duties other than those set forth in our partnership agreement, including fiduciary duties, to the fullest extentpermitted by law;•permits our General Partner to make a number of decisions in its “sole discretion,” which standard entitles our General Partner to consider only theinterests and factors that it desires, and it has no duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates orany limited partner;•provides that our General Partner is entitled to make other decisions in its “reasonable discretion;”•generally provides that affiliated transactions and resolutions of conflicts of interest must be “fair and reasonable” to us and that, in determining whethera transaction or resolution is “fair and reasonable,” our General Partner may consider the interests of all parties involved, including its own;•provides that unless our General Partner has acted in bad faith, the action taken by our General Partner shall not constitute a breach of its fiduciary duty;•provides that our General Partner may resolve any conflicts of interest involving us and our General Partner and its affiliates, and any resolution of aconflict of interest by our General Partner that is “fair and reasonable” to us will be deemed approved by all partners, including the Unitholders, and willnot constitute a breach of the partnership agreement;•provides that our General Partner may, but is not required, in connection with its resolution of a conflict of interest, to seek “special approval” of suchresolution by appointing a conflicts committee of the General Partner’s board of directors composed of two or more independent directors to considersuch conflicts of interest and to recommend action to the board of directors, and any resolution of the conflict of interest by the conflicts committee shallbe conclusively deemed “fair and reasonable” to us;•provides that our General Partner may consult with consultants and advisors and, subject to certain restrictions, is conclusively deemed to have acted ingood faith when it acts in reliance on the opinion of such consultants and advisors; and•provides that our General Partner and its officers and directors will not be liable for monetary damages to us, our limited partners or assignees for errors ofjudgment or for any acts or omissions if our General Partner and those other persons acted in good faith.In order to become a limited partner of our partnership, a Unitholder is required to agree to be bound by the provisions in our partnership agreement,including the provisions discussed above.Some of our executive officers and directors face potential conflicts of interest in managing our business.Certain of our executive officers and directors are also officers and/or directors of ETE. These relationships may create conflicts of interest regardingcorporate opportunities and other matters. The resolution of any such conflicts may not always be in our or our Unitholders’ best interests. In addition, theseoverlapping executive officers and directors allocate their time among us and ETE. These officers and directors face potential conflicts regarding theallocation of their time, which may adversely affect our business, results of operations and financial condition.The General Partner’s absolute discretion in determining the level of cash reserves may adversely affect our ability to make cash distributions to ourUnitholders.Our partnership agreement requires the General Partner to deduct from operating surplus cash reserves that in its reasonable discretion are necessary to fundour future operating expenditures. In addition, our partnership agreement permits the General Partner to reduce available cash by establishing cash reservesfor the proper conduct of our business, to comply with applicable law or agreements to which we are a party or to provide funds for future distributions topartners. These cash reserves will affect the amount of cash available for distribution to Unitholders.35 Table of ContentsOur General Partner has conflicts of interest and limited fiduciary responsibilities that may permit our General Partner to favor its own interests to thedetriment of Unitholders.ETE indirectly owns our General Partner and as a result controls us. The directors and officers of our General Partner and its affiliates have fiduciary duties tomanage our General Partner in a manner that is beneficial to ETE, the sole owner of our General Partner. At the same time, our General Partner hascontractually-limited fiduciary duties to our Unitholders. Therefore, our General Partner’s duties to us may conflict with the duties of its officers and directorsto ETE as its sole owner. As a result of these conflicts of interest, our General Partner may favor its own interest or those of ETE or their owners or affiliatesover the interest of our Unitholders.Such conflicts may arise from, among others, the following:•Our partnership agreement limits the liability and reduces the fiduciary duties of our General Partner while also restricting the remedies available to ourUnitholders for actions that, without these limitations, might constitute breaches of fiduciary duty. Unitholders are deemed to have consented to someactions and conflicts of interest that might otherwise be deemed a breach of fiduciary or other duties under applicable state law. Our General Partner isallowed to take into account the interests of parties in addition to us in resolving conflicts of interest, thereby limiting its fiduciary duties to us.•Our General Partner is allowed to take into account the interests of parties in addition to us, including ETE, in resolving conflicts of interest, therebylimiting its fiduciary duties to us.•Our General Partner’s affiliates, including ETE, are not prohibited from engaging in other businesses or activities, including those in direct competitionwith us.•Our General Partner determines the amount and timing of our asset purchases and sales, capital expenditures, borrowings, repayments of debt, issuancesof equity and debt securities and cash reserves, each of which can affect the amount of cash that is distributed to Unitholders and to ETE.•Neither our partnership agreement nor any other agreement requires ETE or its affiliates to pursue a business strategy that favors us. The directors andofficers of the general partners of ETE have a fiduciary duty to make decisions in the best interest of their members, limited partners and Unitholders,which may be contrary to our best interests.•Some of the directors and officers of ETE who provide advice to us also may devote significant time to the businesses of ETE and will be compensatedby them for their services.•Our General Partner determines which costs, including allocated overhead costs, are reimbursable by us.•Our General Partner is allowed to resolve any conflicts of interest involving us and our General Partner and its affiliates, and any resolution of a conflictof interest by our General Partner that is fair and reasonable to us will be deemed approved by all partners and will not constitute a breach of thepartnership agreement.•Our General Partner controls the enforcement of obligations owed to us by it.•Our General Partner decides whether to retain separate counsel, accountants or others to perform services for us.•Our General Partner is not restricted from causing us to pay it or its affiliates for any services rendered on terms that are fair and reasonable to us orentering into additional contractual arrangements with any of these entities on our behalf.•Our General Partner intends to limit its liability regarding our contractual and other obligations and, in some circumstances, may be entitled to beindemnified by us.•In some instances, our General Partner may cause us to borrow funds in order to permit the payment of distributions, even if the purpose or effect of theborrowing is to make incentive distributions.Affiliates of our General Partner may compete with us.Except as provided in our partnership agreement, affiliates and related parties of our General Partner are not prohibited from engaging in other businesses oractivities, including those that might be in direct competition with us.Risks Related to Our BusinessWe do not control, and therefore may not be able to cause or prevent certain actions by, certain of our joint ventures.Certain of our joint ventures have their own governing boards, and we may not control all of the decisions of those boards. Consequently, it may be difficultor impossible for us to cause the joint venture entity to take actions that we believe would be in our or the joint venture’s best interests. Likewise, we may beunable to prevent actions of the joint venture.36 Table of ContentsWe are exposed to the credit risk of our customers and derivative counterparties, and an increase in the nonpayment and nonperformance by ourcustomers or derivative counterparties could reduce our ability to make distributions to our Unitholders.The risks of nonpayment and nonperformance by our customers are a major concern in our business. Participants in the energy industry have been subjectedto heightened scrutiny from the financial markets in light of past collapses and failures of other energy companies. We are subject to risks of loss resultingfrom nonpayment or nonperformance by our customers. The current commodity price volatility and the tightening of credit in the financial markets maymake it more difficult for customers to obtain financing and, depending on the degree to which this occurs, there may be a material increase in thenonpayment and nonperformance by our customers. To the extent one or more of our customers is in financial distress or commences bankruptcyproceedings, contracts with these customers may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code.In addition, our risk management activities are subject to the risks that a counterparty may not perform its obligation under the applicable derivativeinstrument, the terms of the derivative instruments are imperfect, and our risk management policies and procedures are not properly followed. Any materialnonpayment or nonperformance by our customers or our derivative counterparties could reduce our ability to make distributions to our Unitholders. Anysubstantial increase in the nonpayment and nonperformance by our customers could have a material effect on our results of operations and operating cashflows.Income from our midstream, transportation, terminalling and storage operations is exposed to risks due to fluctuations in the demand for and price ofnatural gas, NGLs and oil that are beyond our control.The prices for natural gas, NGLs and oil (including refined petroleum products) reflect market demand that fluctuates with changes in global and UnitedStates economic conditions and other factors, including:•the level of domestic natural gas, NGL, and oil production;•the level of natural gas, NGL, and oil imports and exports, including liquefied natural gas;•actions taken by natural gas and oil producing nations;•instability or other events affecting natural gas and oil producing nations;•the impact of weather and other events of nature on the demand for natural gas, NGLs and oil;•the availability of storage, terminal and transportation systems, and refining, processing and treating facilities;•the price, availability and marketing of competitive fuels;•the demand for electricity;•activities by non-governmental organizations to limit certain sources of funding for the energy sector or restrict the exploration, development andproduction of oil and natural gas;•the cost of capital needed to maintain or increase production levels and to construct and expand facilities•the impact of energy conservation and fuel efficiency efforts; and•the extent of governmental regulation, taxation, fees and duties.In the past, the prices of natural gas, NGLs and oil have been extremely volatile, and we expect this volatility to continue.Any loss of business from existing customers or our inability to attract new customers due to a decline in demand for natural gas, NGLs, or oil could have amaterial adverse effect on our revenues and results of operations. In addition, significant price fluctuations for natural gas, NGL and oil commodities couldmaterially affect our profitability.We are affected by competition from other midstream, transportation, terminalling and storage companies.We experience competition in all of our business segments. With respect to our midstream operations, we compete for both natural gas supplies andcustomers for our services. Our competitors include major integrated oil companies, interstate and intrastate pipelines and companies that gather, compress,treat, process, transport, store and market natural gas.Our natural gas and NGL transportation pipelines and storage facilities compete with other interstate and intrastate pipeline companies and storage providersin the transportation and storage of natural gas and NGLs. The principal elements of competition among pipelines are rates, terms of service, access to sourcesof supply and the flexibility and reliability of service. Natural gas and NGLs also competes with other forms of energy, including electricity, coal, fuel oilsand renewable or alternative energy. Competition among fuels and energy supplies is primarily based on price; however, non-price factors, includinggovernmental regulation, environmental impacts, efficiency, ease of use and handling, and the availability of subsidies and tax benefits also affectscompetitive outcomes.37 Table of ContentsIn markets served by our NGL pipelines, we compete with other pipeline companies and barge, rail and truck fleet operations. We also face competition withother storage and fractionation facilities based on fees charged and the ability to receive, distribute and/or fractionate the customer’s products.Our crude oil and refined petroleum products pipelines face significant competition from other pipelines for large volume shipments. These operations alsoface competition from trucks for incremental and marginal volumes in the areas we serve. Further, our crude and refined product terminals compete withterminals owned by integrated petroleum companies, refining and marketing companies, independent terminal companies and distribution companies withmarketing and trading operations.We may be unable to retain or replace existing midstream, transportation, terminalling and storage customers or volumes due to declining demand orincreased competition in oil, natural gas and NGL markets, which would reduce our revenues and limit our future profitability.The retention or replacement of existing customers and the volume of services that we provide at rates sufficient to maintain or increase current revenues andcash flows depends on a number of factors beyond our control, including the price of and demand for oil, natural gas, and NGLs in the markets we serve andcompetition from other service providers.A significant portion of our sales of natural gas are to industrial customers and utilities. As a consequence of the volatility of natural gas prices and increasedcompetition in the industry and other factors, industrial customers, utilities and other gas customers are increasingly reluctant to enter into long-termpurchase contracts. Many customers purchase natural gas from more than one supplier and have the ability to change suppliers at any time. Some of thesecustomers also have the ability to switch between gas and alternate fuels in response to relative price fluctuations in the market. Because there are manycompanies of greatly varying size and financial capacity that compete with us in the marketing of natural gas, we often compete in natural gas sales marketsprimarily on the basis of price.We also receive a substantial portion of our revenues by providing natural gas gathering, processing, treating, transportation and storage services. While asubstantial portion of our services are sold under long-term contracts for reserved service, we also provide service on an unreserved or short-term basis.Demand for our services may be substantially reduced due to changing market prices. Declining prices may result in lower rates of natural gas productionresulting in less use of services, while rising prices may diminish consumer demand and also limit the use of services. In addition, our competitors may attractour customers’ business. If demand declines or competition increases, we may not be able to sustain existing levels of unreserved service or renew or extendlong-term contracts as they expire or we may reduce our rates to meet competitive pressures.Revenue from our NGL transportation systems and refined products storage is also exposed to risks due to fluctuations in demand for transportation andstorage service as a result of unfavorable commodity prices, competition from nearby pipelines, and other factors. We receive substantially all of ourtransportation revenues through dedicated contracts under which the customer agrees to deliver the total output from particular processing plants that areconnected only to our transportation system. Reduction in demand for natural gas or NGLs due to unfavorable prices or other factors, however, may resultlower rates of production under dedicated contracts and lower demand for our services. In addition, our refined products storage revenues are primarilyderived from fixed capacity arrangements between us and our customers, a portion of our revenue is derived from fungible storage and throughputarrangements, under which our revenue is more dependent upon demand for storage from our customers.The volume of crude oil and products transported through our oil pipelines and terminal facilities depends on the availability of attractively priced crude oiland refined products in the areas serviced by our assets. A period of sustained price reductions for crude oil or refined products could lead to a decline indrilling activity, production and refining of crude oil, or import levels in these areas. A period of sustained increases in the price of crude oil or productssupplied from or delivered to any of these areas could materially reduce demand for crude oil or refined in these areas. In either case, the volumes of crude oilor products transported in our oil pipelines and terminal facilities could decline.The loss of existing customers by our midstream, transportation, terminalling and storage facilities or a reduction in the volume of the services our customerspurchase from us, or our inability to attract new customers and service volumes would negatively affect our revenues, be detrimental to our growth, andadversely affect our results of operations.Our midstream facilities and transportation pipelines are attached to basins with naturally declining production, which we may not be able to replace withnew sources of supply.In order to maintain or increase throughput levels on our gathering systems and transportation pipeline systems and asset utilization rates at our treating andprocessing plants, we must continually contract for new natural gas supplies and natural gas transportation services.38 Table of ContentsA substantial portion of our assets, including our gathering systems and our processing and treating plants, are connected to natural gas reserves and wellsthat experience declining production over time. Our gas transportation pipelines are also dependent upon natural gas production in areas served by ourgathering systems or in areas served by other gathering systems or transportation pipelines that connect with our transportation pipelines. We may not be ableto obtain additional contracts for natural gas supplies for our natural gas gathering systems, and we may be unable to maintain or increase the levels ofnatural gas throughput on our transportation pipelines. The primary factors affecting our ability to connect new supplies of natural gas to our gatheringsystems include our success in contracting for existing natural gas supplies that are not committed to other systems and the level of drilling activity andproduction of natural gas near our gathering systems or in areas that provide access to our transportation pipelines or markets to which our systems connect.We have no control over the level of drilling activity in our areas of operation, the amount of reserves underlying the wells and the rate at which productionfrom a well will decline. In addition, we have no control over producers or their production and contracting decisions.While a substantial portion of our services are provided under long-term contracts for reserved service, we also provide service on an unreserved basis. Thereserves available through the supply basins connected to our gathering, processing, treating, transportation and storage facilities may decline and may notbe replaced by other sources of supply. A decrease in development or production activity could cause a decrease in the volume of unreserved services weprovide and a decrease in the number and volume of our contracts for reserved transportation service over the long run, which in each case would adverselyaffect our revenues and results of operations.If we are unable to replace any significant volume declines with additional volumes from other sources, our results of operations and cash flows could bematerially and adversely affected.The profitability of certain activities in our natural gas gathering, processing, transportation and storage operations are largely dependent upon naturalgas commodity prices, price spreads between two or more physical locations and market demand for natural gas and NGLs.For a portion of the natural gas gathered on our systems, we purchase natural gas from producers at the wellhead and then gather and deliver the natural gas topipelines where we typically resell the natural gas under various arrangements, including sales at index prices. Generally, the gross margins we realize underthese arrangements decrease in periods of low natural gas prices.We also enter into percent-of-proceeds arrangements, keep-whole arrangements, and processing fee agreements pursuant to which we agree to gather andprocess natural gas received from the producers.Under percent-of-proceeds arrangements, we generally sell the residue gas and NGLs at market prices and remit to the producers an agreed upon percentage ofthe proceeds based on an index price. In other cases, instead of remitting cash payments to the producer, we deliver an agreed upon percentage of the residuegas and NGL volumes to the producer and sell the volumes we keep to third parties at market prices. Under these arrangements, our revenues and grossmargins decline when natural gas prices and NGL prices decrease. Accordingly, a decrease in the price of natural gas or NGLs could have an adverse effect onour revenues and results of operations.Under keep-whole arrangements, we generally sell the NGLs produced from our gathering and processing operations at market prices. Because the extractionof the NGLs from the natural gas during processing reduces the Btu content of the natural gas, we must either purchase natural gas at market prices for returnto producers or make a cash payment to producers equal to the value of this natural gas. Under these arrangements, our gross margins generally decrease whenthe price of natural gas increases relative to the price of NGLs.When we process the gas for a fee under processing fee agreements, we may guarantee recoveries to the producer. If recoveries are less than those guaranteedto the producer, we may suffer a loss by having to supply liquids or its cash equivalent to keep the producer whole.We also receive fees and retain gas in kind from our natural gas transportation and storage customers. Our fuel retention fees and the value of gas that weretain in kind are directly affected by changes in natural gas prices. Decreases in natural gas prices tend to decrease our fuel retention fees and the value ofretained gas.In addition, we receive revenue from our off-gas processing and fractionating system in south Louisiana primarily through customer agreements that are acombination of keep-whole and percent-of-proceeds arrangements, as well as from transportation and fractionation fees. Consequently, a large portion of ouroff-gas processing and fractionation revenue is exposed to risks due to fluctuations in commodity prices. In addition, a decline in NGL prices could cause adecrease in demand for our off-gas processing and fractionation services and could have an adverse effect on our results of operations.39 Table of ContentsFor our midstream segment, we generally analyze gross margin based on fee-based margin (which includes revenues from processing fee arrangements) andnon-fee based margin (which includes gross margin earned on percent-of-proceeds and keep-whole arrangements). For the years ended December 31, 2017,2016 and 2015, gross margin from our midstream segment totaled $2.18 billion, $1.80 billion and $1.79 billion, respectively, of which fee-based revenuesconstituted 78%, 86% and 88%, respectively, and non-fee based margin constituted 22%, 14% and 12%, respectively. The amount of gross margin earned byour midstream segment from fee-based and non-fee based arrangements (individually and as a percentage of total revenues) will be impacted by the volumesassociated with both types of arrangements, as well as commodity prices; therefore, the dollar amounts and the relative magnitude of gross margin from fee-based and non-fee based arrangements in future periods may be significantly different from results reported in previous periods.A material decrease in demand or distribution of crude oil available for transport through our pipelines or terminal facilities could materially andadversely affect our results of operations, financial position, or cash flows.The volume of crude oil transported through our crude oil pipelines and terminal facilities depends on the availability of attractively priced crude oilproduced or received in the areas serviced by our assets. A period of sustained crude oil price declines could lead to a decline in drilling activity, productionand import levels in these areas. Similarly, a period of sustained increases in the price of crude oil supplied from any of these areas, as compared to alternativesources of crude oil available to our customers, could materially reduce demand for crude oil in these areas. In either case, the volumes of crude oiltransported in our crude oil pipelines and terminal facilities could decline, and it could likely be difficult to secure alternative sources of attractively pricedcrude oil supply in a timely fashion or at all. If we are unable to replace any significant volume declines with additional volumes from other sources, ourresults of operations, financial position, or cash flows could be materially and adversely affected.An interruption of supply of crude oil to our facilities could materially and adversely affect our results of operations and revenues.While we are well positioned to transport and receive crude oil by pipeline, marine transport and trucks, rail transportation also serves as a critical link in thesupply of domestic crude oil production to United States refiners, especially for crude oil from regions such as the Bakken that are not sourced near pipelinesor waterways that connect to all of the major United States refining centers. Federal regulators have issued a safety advisory warning that Bakken crude oilmay be more volatile than many other North American crude oils and reinforcing the requirement to properly test, characterize, classify, and, if applicable,sufficiently degasify hazardous materials prior to and during transportation. The domestic crude oil received by our facilities, especially from the Bakkenregion, may be transported by railroad. If the ability to transport crude oil by rail is disrupted because of accidents, weather interruptions, governmentalregulation, congestion on rail lines, terrorism, other third-party action or casualty or other events, then we could experience an interruption of supply ordelivery or an increased cost of receiving crude oil, and could experience a decline in volumes received. Recent railcar accidents in Quebec, Alabama, NorthDakota, Pennsylvania and Virginia, in each case involving trains carrying crude oil from the Bakken region, have led to increased legislative and regulatoryscrutiny over the safety of transporting crude oil by rail. In 2015, the DOT, through the PHMSA, issued a rule implementing new rail car standards andrailroad operating procedures. Changing operating practices, as well as new regulations on tank car standards and shipper classifications, could increase thetime required to move crude oil from production areas of facilities, increase the cost of rail transportation, and decrease the efficiency of transportation ofcrude oil by rail, any of which could materially reduce the volume of crude oil received by rail and adversely affect our financial condition, results ofoperations, and cash flows.The use of derivative financial instruments could result in material financial losses by us.From time to time, we have sought to reduce our exposure to fluctuations in commodity prices and interest rates by using derivative financial instruments andother risk management mechanisms and by our trading, marketing and/or system optimization activities. To the extent that we hedge our commodity priceand interest rate exposures, we forgo the benefits we would otherwise experience if commodity prices or interest rates were to change in our favor.The accounting standards regarding hedge accounting are very complex, and even when we engage in hedging transactions that are effective economically(whether to mitigate our exposure to fluctuations in commodity prices, or to balance our exposure to fixed and variable interest rates), these transactions maynot be considered effective for accounting purposes. Accordingly, our consolidated financial statements may reflect some volatility due to these hedges, evenwhen there is no underlying economic impact at that point. It is also not always possible for us to engage in a hedging transaction that completely mitigatesour exposure to commodity prices. Our consolidated financial statements may reflect a gain or loss arising from an exposure to commodity prices for whichwe are unable to enter into a completely effective hedge.In addition, our derivatives activities can result in losses. Such losses could occur under various circumstances, including if a counterparty does not performits obligations under the derivative arrangement, the hedge is imperfect, commodity prices move unfavorably related to our physical or financial positions orhedging policies and procedures are not followed.40 Table of ContentsOur revenues depend on our customers’ ability to use our pipelines and third-party pipelines over which we have no control.Our natural gas transportation, storage and NGL businesses depend, in part, on our customers’ ability to obtain access to pipelines to deliver gas to us andreceive gas from us. Many of these pipelines are owned by parties not affiliated with us. Any interruption of service on our pipelines or third-party pipelinesdue to testing, line repair, reduced operating pressures, or other causes or adverse change in terms and conditions of service could have a material adverseeffect on our ability, and the ability of our customers, to transport natural gas to and from our pipelines and facilities and a corresponding material adverseeffect on our transportation and storage revenues. In addition, the rates charged by interconnected pipelines for transportation to and from our facilities affectthe utilization and value of our storage services. Significant changes in the rates charged by those pipelines or the rates charged by other pipelines withwhich the interconnected pipelines compete could also have a material adverse effect on our storage revenues.Shippers using our oil pipelines and terminals are also dependent upon our pipelines and connections to third-party pipelines to receive and deliver crude oiland products. Any interruptions or reduction in the capabilities of these pipelines due to testing, line repair, reduced operating pressures, or other causescould result in reduced volumes transported in our pipelines or through our terminals. Similarly, if additional shippers begin transporting volume overinterconnecting oil pipelines, the allocations of pipeline capacity to our existing shippers on these interconnecting pipelines could be reduced, which alsocould reduce volumes transported in its pipelines or through our terminals. Allocation reductions of this nature are not infrequent and are beyond our control.Any such interruptions or allocation reductions that, individually or in the aggregate, are material or continue for a sustained period of time could have amaterial adverse effect on our results of operations, financial position, or cash flows.The inability to continue to access lands owned by third parties could adversely affect our ability to operate and our financial results.Our ability to operate our pipeline systems on certain lands owned by third parties, will depend on our success in maintaining existing rights-of-way andobtaining new rights-of-way on those lands. We are parties to rights-of-way agreements, permits and licenses authorizing land use with numerous parties,including, private land owners, governmental entities, Native American tribes, rail carriers, public utilities and others. Our ability to secure extensions ofexisting agreements, permits and licenses is essential to our continuing business operations, and securing additional rights-of-way will be critical to ourability to pursue expansion projects. We cannot provide any assurance that we will be able to maintain access to existing rights-of-way upon the expirationof the current grants, that all of the rights-of-way will be obtained in a timely fashion or that we will acquire new rights-of-way as needed.Further, whether we have the power of eminent domain for our pipelines varies from state to state, depending upon the type of pipeline and the laws of theparticular state and the ownership of the land to which we seek access. When we exercise eminent down rights or negotiate private agreements cases, we mustcompensate landowners for the use of their property and, in eminent domain actions, such compensation may be determined by a court. The inability toexercise the power of eminent domain could negatively affect our business if we were to lose the right to use or occupy the property on which our pipelinesare located. For example, following a recent decision issued in May 2017 by the federal Tenth Circuit Court of Appeals, tribal ownership of even a very smallfractional interest in an allotted land, that is, tribal land owned or at one time owned by an individual Indian landowner, bars condemnation of any interest inthe allotment. Consequently, the inability to condemn such allotted lands under circumstances where an existing pipeline rights-of-way may soon lapse orterminate serves as an additional impediment for pipeline operators. Any loss of rights with respect to our real property, through our inability to renew right-of-way contracts or otherwise, could have a material adverse effect on our business, results of operations, financial condition and ability to make cashdistributions to you.We may not be able to fully execute our growth strategy if we encounter increased competition for qualified assets.Our strategy contemplates growth through the development and acquisition of a wide range of midstream, transportation, storage and other energyinfrastructure assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses to enhanceour ability to compete effectively and diversify our asset portfolio, thereby providing more stable cash flow. We regularly consider and enter into discussionsregarding the acquisition of additional assets and businesses, stand-alone development projects or other transactions that we believe will presentopportunities to realize synergies and increase our cash flow.Consistent with our strategy, we may, from time to time, engage in discussions with potential sellers regarding the possible acquisition of additional assets orbusinesses. Such acquisition efforts may involve our participation in processes that involve a number of potential buyers, commonly referred to as “auction”processes, as well as situations in which we believe we are the only party or one of a very limited number of potential buyers in negotiations with thepotential seller. We cannot give assurance that our acquisition efforts will be successful or that any acquisition will be completed on terms consideredfavorable to us.In addition, we are experiencing increased competition for the assets we purchase or contemplate purchasing. Increased competition for a limited pool ofassets could result in us losing to other bidders more often or acquiring assets at higher prices, both of which41 Table of Contentswould limit our ability to fully execute our growth strategy. Inability to execute our growth strategy may materially adversely impact our results ofoperations.An impairment of goodwill and intangible assets could reduce our earnings.As of December 31, 2017, our consolidated balance sheet reflected $3.12 billion of goodwill and $5.31 billion of intangible assets. Goodwill is recordedwhen the purchase price of a business exceeds the fair value of the tangible and separately measurable intangible net assets. Accounting principles generallyaccepted in the United States require us to test goodwill for impairment on an annual basis or when events or circumstances occur, indicating that goodwillmight be impaired. Long-lived assets such as intangible assets with finite useful lives are reviewed for impairment whenever events or changes incircumstances indicate that the carrying amount may not be recoverable. If we determine that any of our goodwill or intangible assets were impaired, wewould be required to take an immediate charge to earnings with a correlative effect on partners’ capital and balance sheet leverage as measured by debt tototal capitalization.During the fourth quarter of 2017, the Partnership performed goodwill impairment tests on our reporting units and recognized goodwill impairments of $262million in the interstate transportation and storage segment, $79 million in the NGL and refined products transportation and services segment and $452million in the all other segment primarily due to changes in assumptions related to projected future revenues and cash flows from the dates the goodwill wasoriginally recorded.During the fourth quarter of 2016, we performed goodwill impairment tests on our reporting units and recognized goodwill impairments of $638 million inthe interstate transportation and storage segment and $32 million in the midstream segment. These goodwill impairments were primarily due to decreases inprojected future revenues and cash flows driven by declines in commodity prices and changes in the markets that these assets serve. In 2015, we recordedgoodwill impairments of $99 million related to Transwestern due primarily to the market declines in current and expected future commodity prices in thefourth quarter of 2015 and $106 million related to Lone Star Refinery Services due primarily to changes in assumptions related to potential future revenues aswell as the market declines in current and expected future commodity prices, as well as $24 million of intangible asset impairments related to Lone Star NGLRefinery Services primarily due to the economic obsolescence identified as a result of expected decrease in future cash flows.If we do not make acquisitions on economically acceptable terms, our future growth could be limited.Our results of operations and our ability to grow and to increase distributions to Unitholders will depend in part on our ability to make acquisitions that areaccretive to our distributable cash flow per unit.We may be unable to make accretive acquisitions for any of the following reasons, among others:•because we are unable to identify attractive acquisition candidates or negotiate acceptable purchase contracts with them;•because we are unable to raise financing for such acquisitions on economically acceptable terms; or•because we are outbid by competitors, some of which are substantially larger than us and have greater financial resources and lower costs of capital thenwe do.Furthermore, even if we consummate acquisitions that we believe will be accretive, those acquisitions may in fact adversely affect our results of operations orresult in a decrease in distributable cash flow per unit. Any acquisition involves potential risks, including the risk that we may:•fail to realize anticipated benefits, such as new customer relationships, cost-savings or cash flow enhancements;•decrease our liquidity by using a significant portion of our available cash or borrowing capacity to finance acquisitions;•significantly increase our interest expense or financial leverage if we incur additional debt to finance acquisitions;•encounter difficulties operating in new geographic areas or new lines of business;•incur or assume unanticipated liabilities, losses or costs associated with the business or assets acquired for which we are not indemnified or for which theindemnity is inadequate;•be unable to hire, train or retrain qualified personnel to manage and operate our growing business and assets;•less effectively manage our historical assets, due to the diversion of management’s attention from other business concerns; or•incur other significant charges, such as impairment of goodwill or other intangible assets, asset devaluation or restructuring charges.42 Table of ContentsIf we consummate future acquisitions, our capitalization and results of operations may change significantly. As we determine the application of our funds andother resources, Unitholders will not have an opportunity to evaluate the economic, financial and other relevant information that we will consider.Integration of assets acquired in past acquisitions or future acquisitions with our existing business will be a complex and time-consuming process. Afailure to successfully integrate the acquired assets with our existing business in a timely manner may have a material adverse effect on our business,financial condition, results of operations or cash available for distribution to our unitholders.The difficulties of integrating past and future acquisitions with our business include, among other things:•operating a larger combined organization in new geographic areas and new lines of business;•hiring, training or retaining qualified personnel to manage and operate our growing business and assets;•integrating management teams and employees into existing operations and establishing effective communication and information exchange with suchmanagement teams and employees;•diversion of management’s attention from our existing business;•assimilation of acquired assets and operations, including additional regulatory programs;•loss of customers or key employees;•maintaining an effective system of internal controls in compliance with the Sarbanes-Oxley Act of 2002 as well as other regulatory compliance andcorporate governance matters; and•integrating new technology systems for financial reporting.If any of these risks or other unanticipated liabilities or costs were to materialize, then desired benefits from past acquisitions and future acquisitions resultingin a negative impact to our future results of operations. In addition, acquired assets may perform at levels below the forecasts used to evaluate theiracquisition, due to factors beyond our control. If the acquired assets perform at levels below the forecasts, then our future results of operations could benegatively impacted.Also, our reviews of proposed business or asset acquisitions are inherently imperfect because it is generally not feasible to perform an in-depth review of eachsuch proposal given time constraints imposed by sellers. Even if performed, a detailed review of assets and businesses may not reveal existing or potentialproblems, and may not provide sufficient familiarity with such business or assets to fully assess their deficiencies and potential. Inspections may not beperformed on every asset, and environmental problems, may not be observable even when an inspection is undertaken.If we do not continue to construct new pipelines, our future growth could be limited.Our results of operations and ability to grow and to increase distributable cash flow per unit will depend, in part, on our ability to construct pipelines that areaccretive to our distributable cash flow. We may be unable to construct pipelines that are accretive to distributable cash flow for any of the following reasons,among others:•we are unable to identify pipeline construction opportunities with favorable projected financial returns;•we are unable to obtain necessary governmental approvals and contracts with qualified contractors and vendors on acceptable terms;•we are unable to raise financing for our identified pipeline construction opportunities; or•we are unable to secure sufficient transportation commitments from potential customers due to competition from other pipeline construction projects orfor other reasons.Furthermore, even if we construct a pipeline that we believe will be accretive, the pipeline may in fact adversely affect our results of operations or results fromthose projected prior to commencement of construction and other factors.Expanding our business by constructing new pipelines and related facilities subjects us to risks.One of the ways that we have grown our business is through the construction of additions to our existing gathering, compression, treating, processing andtransportation systems. The construction of new pipelines and related facilities (or the improvement and repair of existing facilities) involves numerousregulatory, environmental, political and legal uncertainties beyond our control and requires the expenditure of significant amounts of capital that we will berequired to finance through borrowings, the issuance of additional equity or from operating cash flow. If we undertake these projects, they may not becompleted on schedule, at all, or at the budgeted cost. A variety of factors outside our control, such as weather, natural disasters and difficulties in obtainingpermits43 Table of Contentsand rights-of-way or other regulatory approvals, as well as the performance by third-party contractors, may result in increased costs or delays in construction.Cost overruns or delays in completing a project could have a material adverse effect on our results of operations and cash flows. Moreover, our revenues maynot increase immediately following the completion of a particular project. For instance, if we build a new pipeline, the construction will occur over anextended period of time, but we may not materially increase our revenues until long after the project’s completion. In addition, the success of a pipelineconstruction project will likely depend upon the level of oil and natural gas exploration and development drilling activity and the demand for pipelinetransportation in the areas proposed to be serviced by the project as well as our ability to obtain commitments from producers in the area to utilize the newlyconstructed pipelines. In this regard, we may construct facilities to capture anticipated future growth in oil or natural gas production in a region in which suchgrowth does not materialize. As a result, new facilities may be unable to attract enough throughput or contracted capacity reservation commitments toachieve our expected investment return, which could adversely affect our results of operations and financial condition.We depend on certain key producers for our supply of natural gas and the loss of any of these key producers could adversely affect our financial results.Certain producers who are connected to our systems represent a material source of our supply of natural gas. We are not the only option available to theseproducers for disposition of the natural gas they produce. To the extent that these and other producers may reduce the volumes of natural gas that they supplyus, we would be adversely affected unless we were able to acquire comparable supplies of natural gas from other producers.Our intrastate transportation and storage and interstate transportation and storage operations depend on key customers to transport natural gas throughour pipelines and the pipelines of our joint ventures.During 2017, Trafigura US Inc., KMI, and Calpine Energy Services L.P. collectively accounted for approximately 36% of our intrastate transportation andstorage revenues. During 2017, Chesapeake Energy Marketing, Inc., EnCana Marketing (USA), Inc. and Shell Energy North America (US), L.P., collectivelyaccounted for 19% of our interstate transportation and storage revenues.Our joint ventures, FEP and Citrus, also depend on key customers for the transport of natural gas through their pipelines. FEP has a small number of majorshippers with one shipper accounting for approximately 64% of its revenues in 2017 while Citrus has long-term agreements with its top two customers whichaccounted for 61% of its 2017 revenue. For Trans-Pecos and Comanche Trail, CFE International LLC is the sole shipper.The failure of the major shippers on our and our joint ventures’ intrastate and interstate transportation and storage pipelines to fulfill their contractualobligations could have a material adverse effect on our cash flow and results of operations if we or our joint ventures were unable to replace these customersunder arrangements that provide similar economic benefits as these existing contracts.Our interstate natural gas pipelines are subject to laws, regulations and policies governing the rates they are allowed to charge for their services, whichmay prevent us from fully recovering our costs.Laws, regulations and policies governing interstate natural gas pipeline rates could affect the ability of our interstate pipelines to establish rates, to chargerates that would cover future increases in its costs, or to continue to collect rates that cover current costs.We are required to file tariff rates (also known as recourse rates) with the FERC that shippers may pay for interstate natural gas transportation services. Wemay also agree to discount these rates on a not unduly discriminatory basis or negotiate rates with shippers who elect not to pay the recourse rates. The FERCmust approve or accept all rate filings for us to be allowed to charge such rates.The FERC may review existing tariff rates on its own initiative or upon receipt of a complaint filed by a third party. The FERC may, on a prospective basis,order refunds of amounts collected if it finds the rates to have been shown not to be just and reasonable or to have been unduly discriminatory. The FERC hasrecently exercised this authority with respect to several other pipeline companies. If the FERC were to initiate a proceeding against us and find that our rateswere not just and reasonable or unduly discriminatory, the maximum rates we are permitted to charge may be reduced and the reduction could have anadverse effect on our revenues and results of operations.The costs of our interstate pipeline operations may increase and we may not be able to recover all of those costs due to FERC regulation of our rates. If wepropose to change our tariff rates, our proposed rates may be challenged by the FERC or third parties, and the FERC may deny, modify or limit our proposedchanges if we are unable to persuade the FERC that changes would result in just and reasonable rates that are not unduly discriminatory. We also may belimited by the terms of rate case settlement agreements or negotiated rate agreements with individual customers from seeking future rate increases, or we maybe constrained by competitive factors from charging our tariff rates.44 Table of ContentsTo the extent our costs increase in an amount greater than our revenues increase, or there is a lag between our cost increases and our ability to file for andobtain rate increases, our operating results would be negatively affected. Even if a rate increase is permitted by the FERC to become effective, the rateincrease may not be adequate. We cannot guarantee that our interstate pipelines will be able to recover all of our costs through existing or future rates.The ability of interstate pipelines held in tax-pass-through entities, like us, to include an allowance for income taxes as a cost-of-service element in theirregulated rates has been subject to extensive litigation before the FERC and the courts for a number of years. It is currently the FERC’s policy to permitpipelines to include in cost-of-service a tax allowance to reflect actual or potential income tax liability on their public utility income attributable to allpartnership or limited liability company interests, to the extent that the ultimate owners have an actual or potential income tax liability on such income.Whether a pipeline’s owners have such actual or potential income tax liability will be reviewed by the FERC on a case-by-case basis. Under the FERC’spolicy, we thus remain eligible to include an income tax allowance in the tariff rates we charge for interstate natural gas transportation. On December 15,2016, FERC issued a Notice of Inquiry requesting energy industry input on how FERC should address income tax allowances in cost-based rates proposed bypipeline companies organized as part of a master limited partnership. FERC issued the Notice of Inquiry in response to a remand from the United States Courtof Appeals for the D.C. Circuit in United Airlines v. FERC, in which the court determined that FERC had not justified its conclusion that an oil pipelineorganized as a partnership would not “double recover” its taxes under the current policy by both including a tax allowance in its cost-based rates and earninga return on equity calculated on a pre-tax basis. FERC requested comments regarding how to address any double recovery resulting from the Commission’scurrent income tax allowance and rate of return policies. The comment period with respect to the notice of inquiry ended on April 7, 2017. The outcome ofthe inquiry is still pending. We cannot predict whether FERC will successfully justify its conclusion that there is no double recovery of taxes under thesecircumstances or whether FERC will modify its current policy on either income tax allowances or return on equity calculations for pipeline companiesorganized as part of a master limited partnership. However, any modification that reduces or eliminates an income tax allowance for pipeline companiesorganized as part of a master limited partnership or decreases the return on equity for such pipelines could result in an adverse impact on our revenuesassociated with the transportation and storage services we provide pursuant to cost-based rates.Effective January 2018, the 2017 Tax Cuts and Jobs Act changed several provisions of the federal tax code, including a reduction in the maximum corporatetax rate. Following the 2017 Tax Cuts and Jobs Act being signed into law, filings have been made at FERC requesting that FERC require pipelines to lowertheir transportation rates to account for lower taxes. Following the effective date of the law, the FERC orders granting certificates to construct proposedpipeline facilities have directed pipelines proposing new rates for service on those facilities to re-file such rates so that the rates reflect the reduction in thecorporate tax rate, and FERC has issued data requests in pending certificate proceedings for proposed pipeline facilities requesting pipelines to explain theimpacts of the reduction in the corporate tax rate on the rate proposals in those proceedings and to provide re-calculated initial rates for service on theproposed pipeline facilities. FERC may enact other regulations or issue further requests to pipelines regarding the impact of the corporate tax rate change onthe rates. The FERC’s establishment of a just and reasonable rate is based on many components, and the reduction in the corporate tax rate may impact two ofsuch components: the allowance for income taxes and the amount for accumulated deferred income taxes. Because our existing jurisdictional rates wereestablished based on a higher corporate tax rate, FERC or our shippers may challenge these rates in the future, and the resulting new rate may be lower thanthe rates we currently charge.Our interstate natural gas pipelines are subject to laws, regulations and policies governing terms and conditions of service, which could adversely affectour business and results of operations.In addition to rate oversight, the FERC’s regulatory authority extends to many other aspects of the business and operations of our interstate natural gaspipelines, including:•terms and conditions of service;•the types of services interstate pipelines may or must offer their customers;•construction of new facilities;•acquisition, extension or abandonment of services or facilities;•reporting and information posting requirements;•accounts and records; and•relationships with affiliated companies involved in all aspects of the natural gas and energy businesses.Compliance with these requirements can be costly and burdensome. In addition, we cannot guarantee that the FERC will authorize tariff changes and otheractivities we might propose and to undertake in a timely manner and free from potentially burdensome conditions. Future changes to laws, regulations,policies and interpretations thereof may impair our access to capital markets or45 Table of Contentsmay impair the ability of our interstate pipelines to compete for business, may impair their ability to recover costs or may increase the cost and burden ofoperation.The current FERC Chairman announced in December 2017 that FERC will review its policies on certification of natural gas pipelines, including anexamination of its long-standing Policy Statement on Certification of New Interstate Natural Gas Pipeline Facilities, issued in 1999, that is used to determinewhether to grant certificates for new pipeline projects. We are unable to predict what, if any, changes may be proposed that will affect our natural gas pipelinebusiness or when such proposals, if any, might become effective. We do not expect that any change in this policy would affect us in a materially differentmanner than any other similarly sized natural gas pipeline company operating in the United States.Rate regulation or market conditions may not allow us to recover the full amount of increases in the costs of our crude oil, NGL and products pipelineoperations.Transportation provided on our common carrier interstate crude oil, NGL and products pipelines is subject to rate regulation by the FERC, which requiresthat tariff rates for transportation on these oil pipelines be just and reasonable and not unduly discriminatory. If we propose new or changed rates, the FERCor interested persons may challenge those rates and the FERC is authorized to suspend the effectiveness of such rates for up to seven months and toinvestigate such rates. If, upon completion of an investigation, the FERC finds that the proposed rate is unjust or unreasonable, it is authorized to require thecarrier to refund revenues in excess of the prior tariff during the term of the investigation. The FERC also may investigate, upon complaint or on its ownmotion, rates that are already in effect and may order a carrier to change its rates prospectively. Upon an appropriate showing, a shipper may obtainreparations for damages sustained for a period of up to two years prior to the filing of a complaint.The primary ratemaking methodology used by the FERC to authorize increases in the tariff rates of petroleum pipelines is price indexing. The FERC’sratemaking methodologies may limit our ability to set rates based on our costs or may delay the use of rates that reflect increased costs. In October 2016,FERC issued an Advance Notice of Proposed Rulemaking seeking comment on a number of proposals, including: (1) whether the Commission should denyany increase in a rate ceiling or annual index-based rate increase if a pipeline’s revenues exceed total costs by 15% for the prior two years; (2) a newpercentage comparison test that would deny a proposed increase to a pipeline’s rate or ceiling level greater than 5% above the barrel-mile cost changes; and(3) a requirement that all pipelines file indexed ceiling levels annually, with the ceiling levels subject to challenge and restricting the pipeline’s ability tocarry forward the full indexed increase to a future period. The comment period with respect to the proposed rules ended March 17, 2017. FERC has not yettaken any further action on the proposed rule. If the FERC’s indexing methodology changes, the new methodology could materially and adversely affect ourfinancial condition, results of operations or cash flows.Under the EPAct of 1992, certain interstate pipeline rates were deemed just and reasonable or “grandfathered.” Revenues are derived from such grandfatheredrates on most of our FERC-regulated pipelines. A person challenging a grandfathered rate must, as a threshold matter, establish a substantial change since thedate of enactment of the Energy Policy Act, in either the economic circumstances or the nature of the service that formed the basis for the rate. If the FERCwere to find a substantial change in circumstances, then the existing rates could be subject to detailed review and there is a risk that some rates could befound to be in excess of levels justified by the pipeline’s costs. In such event, the FERC could order us to reduce pipeline rates prospectively and to payrefunds to shippers.If the FERC’s petroleum pipeline ratemaking methodologies procedures changes, the new methodology or procedures could adversely affect our businessand results of operations.State regulatory measures could adversely affect the business and operations of our midstream and intrastate pipeline and storage assets.Our midstream and intrastate transportation and storage operations are generally exempt from FERC regulation under the NGA, but FERC regulation stillsignificantly affects our business and the market for our products. The rates, terms and conditions of service for the interstate services we provide in ourintrastate gas pipelines and gas storage are subject to FERC regulation under Section 311 of the NGPA. Our HPL System, East Texas pipeline, Oasis pipelineand ET Fuel System provide such services. Under Section 311, rates charged for transportation and storage must be fair and equitable. Amounts collected inexcess of fair and equitable rates are subject to refund with interest, and the terms and conditions of service, set forth in the pipeline’s statement of operatingconditions, are subject to FERC review and approval. Should the FERC determine not to authorize rates equal to or greater than our costs of service, our cashflow would be negatively affected.Our midstream and intrastate gas and oil transportation pipelines and our intrastate gas storage operations are subject to state regulation. All of the states inwhich we operate midstream assets, intrastate pipelines or intrastate storage facilities have adopted some form of complaint-based regulation, which allowproducers and shippers to file complaints with state regulators in an effort to resolve grievances relating to the fairness of rates and terms of access. The statesin which we operate have ratable take statutes, which generally require gatherers to take, without undue discrimination, production that may be tendered tothe gatherer for46 Table of Contentshandling. Similarly, common purchaser statutes generally require gatherers to purchase without undue discrimination as to source of supply or producer.These statutes have the effect of restricting our right as an owner of gathering facilities to decide with whom we contract to purchase or transport natural gas.Should a complaint be filed in any of these states or should regulation become more active, our business may be adversely affected.Our intrastate transportation operations located in Texas are also subject to regulation as gas utilities by the TRRC. Texas gas utilities must publish the ratesthey charge for transportation and storage services in tariffs filed with the TRRC, although such rates are deemed just and reasonable under Texas law unlesschallenged in a complaint.We are subject to other forms of state regulation, including requirements to obtain operating permits, reporting requirements, and safety rules (see descriptionof federal and state pipeline safety regulation below). Violations of state laws, regulations, orders and permit conditions can result in the modification,cancellation or suspension of a permit, civil penalties and other relief.Certain of our assets may become subject to regulation.The distinction between federally unregulated gathering facilities and FERC-regulated transmission pipelines under the NGA has been the subject ofextensive litigation and may be determined by the FERC on a case-by-case basis, although the FERC has made no determinations as to the status of ourfacilities. Consequently, the classification and regulation of our gathering facilities could change based on future determinations by the FERC, the courts orCongress. If our gas gathering operations become subject to FERC jurisdiction, the result may adversely affect the rates we are able to charge and the serviceswe currently provide, and may include the potential for a termination of our gathering agreements with our customers.Intrastate transportation of NGLs is largely regulated by the state in which such transportation takes place. Lone Star’s NGL Pipeline transports NGLs withinthe state of Texas and is subject to regulation by the TRRC. This NGLs transportation system offers services pursuant to an intrastate transportation tariff onfile with the TRRC. In 2013, Lone Star’s NGL pipeline also commenced the interstate transportation of NGLs, which is subject to FERC’s jurisdiction underthe Interstate Commerce Act and the Energy Policy Act of 1992. Both intrastate and interstate NGL transportation services must be provided in a manner thatis just, reasonable, and non-discriminatory. The tariff rates established for interstate services were based on a negotiated agreement; however, if FERC’sratemaking methodologies were imposed, they may, among other things, delay the use of rates that reflect increased costs and subject us to potentiallyburdensome and expensive operational, reporting and other requirements. In addition, the rates, terms and conditions for shipments of crude oil, petroleumproducts and NGLs on our pipelines are subject to regulation by FERC if the NGLs are transported in interstate or foreign commerce, whether by ourpipelines or other means of transportation. Since we do not control the entire transportation path of all crude oil, petroleum products and NGLs on ourpipelines, FERC regulation could be triggered by our customers’ transportation decisions.In addition, if any of our pipelines were found to have provided services or otherwise operated in violation of the NGA, NGPA, or ICA, this could result in theimposition of administrative and criminal remedies and civil penalties, as well as a requirement to disgorge charges collected for such services in excess ofthe rate established by the FERC. Any of the foregoing could adversely affect revenues and cash flow related to these assets.We may incur significant costs and liabilities resulting from performance of pipeline integrity programs and related repairs.Pursuant to authority under the NGPSA and HLPSA, PHMSA has established a series of rules requiring pipeline operators to develop and implement integritymanagement programs for natural gas transmission and hazardous liquid pipelines that, in the event of a pipeline leak or rupture, could affect HCAs which areareas where a release could have the most significant adverse consequences, including high population areas, certain drinking water sources, and unusuallysensitive ecological areas. These regulations require operators of covered pipelines to:•perform ongoing assessments of pipeline integrity;•identify and characterize applicable threats to pipeline segments that could impact a high consequence area;•improve data collection, integration and analysis;•repair and remediate the pipeline as necessary; and•implement preventive and mitigating actions.In addition, states have adopted regulations similar to existing PHMSA regulations for intrastate gathering and transmission lines. At this time, we cannotpredict the ultimate cost of compliance with applicable pipeline integrity management regulations, as the cost will vary significantly depending on thenumber and extent of any repairs found to be necessary as a result of the pipeline integrity testing. We will continue our pipeline integrity testing programs toassess and maintain the integrity of our pipelines. The results of these tests could cause us to incur significant and unanticipated capital and operatingexpenditures for repairs or upgrades47 Table of Contentsdeemed necessary to ensure the continued safe and reliable operation of our pipelines. Any changes to pipeline safety laws by Congress and regulations byPHMSA that result in more stringent or costly safety standards could have a significant adverse effect on us and similarly situated midstream operators. Forexample, in January 2017, PHMSA issued a final rule for hazardous liquid pipelines that significantly expands the reach of certain PHMSA integritymanagement requirements, such as, for example, periodic assessments, leak detection and repairs, regardless of the pipeline’s proximity to a HCA. The finalrule also imposes new reporting requirements for certain unregulated pipelines, including all hazardous liquid gathering lines. However, the date ofimplementation of this final rule by publication in the Federal Register is uncertain given the recent change in Presidential Administrations. In a secondexample, in April 2016, PHMSA published a proposed rulemaking that would impose new or more stringent requirements for certain natural gas lines andgathering lines including, among other things, expanding certain of PHMSA’s current regulatory safety programs for natural gas pipelines in newly defined“moderate consequence areas” that contain as few as 5 dwellings within a potential impact area; requiring gas pipelines installed before 1970 and thusexcluded from certain pressure testing obligations to be tested to determine their maximum allowable operating pressure (“MAOP”); and requiring certainonshore and offshore gathering lines in Class I areas to comply with damage prevention, corrosion control, public education, MAOP limits, line markers andemergency planning standards. Additional requirements proposed by this proposed rulemaking would increase PHMSA’s integrity management requirementsand also require consideration of seismicity in evaluating threats to pipelines. The changes adopted or proposed by these rulemakings or made in future legalrequirements could have a material adverse effect on our results of operations and costs of transportation services.Federal and state legislative and regulatory initiatives relating to pipeline safety that require the use of new or more stringent safety controls or result inmore stringent enforcement of applicable legal requirements could subject us to increased capital costs, operational delays and costs of operation.The NGPSA and HLPSA were amended by the 2011 Pipeline Safety Act. Among other things, the 2011 Pipeline Safety Act increased the penalties for safetyviolations and directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, automaticor remote-controlled valve use, excess flow valve use, leak detection system installation, testing to confirm that the material strength of certain pipelines areabove 30% of specified minimum yield strength, and operator verification of records confirming the MAOP of certain interstate natural gas transmissionpipelines. Effective April 27, 2017, maximum administrative fines for safety violations were increased to account for inflation, with maximum civil penaltiesset at $209,002 per day, with a maximum of $2,090,022 for a series of violations. In June 2016, the 2016 Pipeline Safety Act was passed, extending PHMSA’sstatutory mandate through 2019 and, among other things, requiring PHMSA to complete certain of its outstanding mandates under the 2011 Pipeline SafetyAct and developing new safety standards for natural gas storage facilities by June 22, 2018. The 2016 Pipeline Safety Act also empowers PHMSA to addressimminent hazards by imposing emergency restrictions, prohibitions and safety measures on owners and operators of natural gas or hazardous liquid pipelinefacilities without prior notice or an opportunity for a hearing. PHMSA issued interim regulations in October 2016 to implement the agency’s expandedauthority to address unsafe pipeline conditions or practices that pose an imminent hazard to life, property, or the environment. The safety enhancementrequirements and other provisions of the 2011 Pipeline Safety Act as further amended by the 2016 Pipeline Safety Act as well as any implementation ofPHMSA rules thereunder or any issuance or reinterpretation of guidance by PHMSA or any state agencies with respect thereto could require us to install newor modified safety controls, pursue additional capital projects, or conduct maintenance programs on an accelerated basis, any or all of which tasks couldresult in our incurring increased operating costs that could be significant and have a material adverse effect on our results of operations or financialcondition.Our business involves the generation, handling and disposal of hazardous substances, hydrocarbons and wastes which activities are subject toenvironmental and worker health and safety laws and regulations that may cause us to incur significant costs and liabilities.Our business is subject to stringent federal, tribal state, and local laws and regulations governing the discharge of materials into the environment, workerhealth and safety and protection of the environment. These laws and regulations may require the acquisition of permits for the construction and operation ofour pipelines, plants and facilities, result in capital expenditures to manage, limit or prevent emissions, discharges or releases of various materials from ourpipelines, plants and facilities, impose specific health and safety standards addressing worker protection, and impose substantial liabilities for pollutionresulting from our construction and operations activities. Several governmental authorities, such as the EPA and analogous state agencies have the power toenforce compliance with these laws and regulations and the permits issued under them and frequently mandate difficult and costly remediation measures andother actions. Failure to comply with these laws, regulations and permits may result in the assessment of significant administrative, civil and criminalpenalties, the imposition of investigatory remedial and corrective action obligations, the occurrence of delays in permitting and completion of projects, andthe issuance of injunctive relief. Certain environmental laws impose strict, joint and several liability for costs required to clean up and restore sites wherehazardous substances, hydrocarbons or wastes have been disposed or released, even under circumstances where the substances, hydrocarbons or wastes havebeen released by a predecessor operator. Moreover, it is not uncommon for neighboring landowners and other third parties48 Table of Contentsto file claims for personal injury and property and natural resource damage allegedly caused by noise, odor or the release of hazardous substances,hydrocarbons or wastes into the environment.We may incur substantial environmental costs and liabilities because of the underlying risk arising out of our operations. Although we have establishedfinancial reserves for our estimated environmental remediation liabilities, additional contamination or conditions may be discovered, resulting in increasedremediation costs, liabilities or natural resource damages that could substantially increase our costs for site remediation projects. Accordingly, we cannotassure you that our current reserves are adequate to cover all future liabilities, even for currently known contamination.Changes in environmental laws and regulations occur frequently, and any such changes that result in more stringent and costly waste handling, emissionstandards, or storage, transport, disposal or remediation requirements could have a material adverse effect on our operations or financial position. Forexample, in October 2015, the EPA published a final rule under the Clean Air Act, lowering the NAAQS for ground-level ozone to 70 parts per billion for the8-hour primary and secondary ozone standards. The EPA published a final rule in November 2017 that issued area designations with respect to ground-levelozone for approximately 85% of the United States counties as either “attainment/unclassifiable” or “unclassifiable” and is expected to issue non-attainmentdesignations for the remaining areas of the United States not addressed under the November 2017 final rule in the first half of 2018. Reclassification of areasor imposition of more stringent standards may make it more difficult to construct new or modified sources of air pollution in newly designated non-attainment areas. Also, states are expected to implement more stringent requirements as a result of this new final rule, which could apply to our customers’operations. Compliance with this final rule or any other new regulations could, among other things, require installation of new emission controls on some ofour equipment, result in longer permitting timelines or new restrictions or prohibitions with respect to permits or projects, and significantly increase ourcapital expenditures and operating costs, which could adversely impact our business. Historically, we have been able to satisfy the more stringent nitrogenoxide emission reduction requirements that affect our compressor units in ozone non-attainment areas at reasonable cost, but there is no assurance that wewill not incur material costs in the future to meet the new, more stringent ozone standard.Product liability claims and litigation could adversely affect our business and results of operations.Product liability is a significant commercial risk. Substantial damage awards have been made in certain jurisdictions against manufacturers and resellersbased upon claims for injuries caused by the use of or exposure to various products. There can be no assurance that product liability claims against us wouldnot have a material adverse effect on our business or results of operations.Along with other refiners, manufacturers and sellers of gasoline, Sunoco, Inc. is a defendant in numerous lawsuits that allege MTBE contamination ingroundwater. Plaintiffs, who include water purveyors and municipalities responsible for supplying drinking water and private well owners, are seekingcompensatory damages (and in some cases injunctive relief, punitive damages and attorneys’ fees) for claims relating to the alleged manufacture anddistribution of a defective product (MTBE-containing gasoline) that contaminates groundwater, and general allegations of product liability, nuisance,trespass, negligence, violation of environmental laws and deceptive business practices. There has been insufficient information developed about theplaintiffs’ legal theories or the facts that would be relevant to an analysis of the ultimate liability to Sunoco, Inc. An adverse determination of liability relatedto these allegations or other product liability claims against Sunoco, Inc. could have a material adverse effect on our business or results of operations.Climate change legislation or regulations restricting emissions of “greenhouse gases” could result in increased operating costs and reduced demand forthe services we provide.Climate change continues to attract considerable public, governmental and scientific attention. As a result, numerous proposals have been made and arelikely to continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of GHGs. These effortshave included consideration of cap-and-trade programs, carbon taxes and GHG reporting and tracking programs, and regulations that directly limit GHGemissions from certain sources. At the federal level, no comprehensive climate change legislation has been implemented to date. The EPA has, however,adopted rules under authority of the Clean Air Act that, among other things, establish PSD construction and Title V operating permit reviews for GHGemissions from certain large stationary sources that are also potential major sources of certain principal, or criteria, pollutant emissions, which reviews couldrequire securing PSD permits at covered facilities emitting GHGs and meeting “best available control technology” standards for those GHG emissions. Inaddition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sourcesin the United States, including, among others, onshore processing, transmission, storage and distribution facilities. In October 2015, the EPA amended andexpanded the GHG reporting requirements to all segments of the oil and natural gas industry, including gathering and boosting facilities and blowdowns ofnatural gas transmission pipelines.Federal agencies also have begun directly regulating emissions of methane, a GHG, from oil and natural gas operations. In June 2016, the EPA published NewSource Performance Standards (“NSPS”), known as Subpart OOOOa, that require certain new,49 Table of Contentsmodified or reconstructed facilities in the oil and natural gas sector to reduce these methane gas and volatile organic compound emissions. These SubpartOOOOa standards will expand previously issued NSPS published by the EPA in 2012 and known as Subpart OOOO, by using certain equipment-specificemissions control practices, requiring additional controls for pneumatic controllers and pumps as well as compressors, and imposing leak detection and repairrequirements for natural gas compressor and booster stations. However, the Subpart OOOOa standards have been subject to attempts by the EPA to stayportions of those standards, and the agency proposed rulemaking in June 2017 to stay the requirements for a period of two years and revisit implementationof Subpart OOOOa in its entirety. The EPA has not yet published a final rule and, as a result, the June 2016 rule remains in effect but future implementation ofthe 2016 standards is uncertain at this time. This rule, should it remain in effect, and any other new methane emission standards imposed on the oil and gassector could result in increased costs to our operations as well as result in delays or curtailment in such operations, which costs, delays or curtailment couldadversely affect our business. Additionally, in December 2015, the United States joined the international community at the 21st Conference of the Parties ofthe United Nations Framework Convention on Climate Change in Paris, France preparing an agreement requiring member countries to review and “representa progression” in their intended nationally determined contributions, which set GHG emission reduction goals every five years beginning in 2020. This“Paris Agreement” was signed by the United States in April 2016 and entered into force in November 2016; however, this agreement does not create anybinding obligations for nations to limit their GHG emissions, but rather includes pledges to voluntarily limit or reduce future emissions. In August 2017, theUnited States State Department informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreementprovides for a four-year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November 2020. TheUnited States’ adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiatedagreement are unclear at this time.The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHGs or otherwise restrictemissions of GHGs could result in increased compliance costs or additional operating restrictions, and could have a material adverse effect on our business,financial condition, demand for our services, results of operations, and cash flows. Recently, activists concerned about the potential effects of climate changehave directed their attention at sources of funding for fossil-fuel energy companies, which has resulted in certain financial institutions, funds and othersources of capital restricting or eliminating their investment in oil and natural gas activities. Ultimately, this could make it more difficult to secure fundingfor exploration and production or midstream activities. Notwithstanding potential risks related to climate change, the International Energy Agency estimatesthat global energy demand will continue to rise and will not peak until after 2040 and that oil and natural gas will continue to represent a substantialpercentage of global energy use over that time. Finally, some scientists have concluded that increasing concentrations of GHG in the atmosphere mayproduce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climateevents that could have an adverse effect on our assets.The swaps regulatory provisions of the Dodd-Frank Act and the rules adopted thereunder could have an adverse effect on our ability to use derivativeinstruments to mitigate the risks of changes in commodity prices and interest rates and other risks associated with our business.Provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and rules adopted by the Commodity Futures TradingCommission (the “CFTC”), the SEC and other prudential regulators establish federal regulation of the physical and financial derivatives, including over-the-counter derivatives market and entities, such as us, participating in that market. While most of these regulations are already in effect, the implementationprocess is still ongoing and the CFTC continues to review and refine its initial rulemakings through additional interpretations and supplementalrulemakings. As a result, any new regulations or modifications to existing regulations could significantly increase the cost of derivative contracts, materiallyalter the terms of derivative contracts, reduce the availability and/or liquidity of derivatives to protect against risks we encounter, reduce our ability tomonetize or restructure our existing derivative contracts, and increase our exposure to less creditworthy counterparties. Any of these consequences couldhave a material adverse effect on our financial condition, results of operations and cash available for distribution to our unitholders.The CFTC has re-proposed speculative position limits for certain futures and option contracts in the major energy markets and for swaps that are theireconomic equivalents, although certain bona fide hedging transactions would be exempt from these position limits provided that various conditions aresatisfied. The CFTC has also finalized a related aggregation rule that requires market participants to aggregate their positions with certain other persons undercommon ownership and control, unless an exemption applies, for purposes of determining whether the position limits have been exceeded. If adopted, therevised position limits rule and its finalized companion rule on aggregation may create additional implementation or operational exposure. In addition to theCFTC federal speculative position limit regime, designated contract markets (“DCMs”) also maintain speculative position limit and accountability regimeswith respect to contracts listed on their platform as well as aggregation requirements similar to the CFTC’s final aggregation rule. Any speculative positionlimit regime, whether imposed at the federal-level or at the DCM-level may impose added operating costs to monitor compliance with such position limitlevels, addressing accountability level concerns and maintaining appropriate exemptions, if applicable.50 Table of ContentsThe Dodd-Frank Act requires that certain classes of swaps be cleared on a derivatives clearing organization and traded on a DCM or other regulatedexchange, unless exempt from such clearing and trading requirements, which could result in the application of certain margin requirements imposed byderivatives clearing organizations and their members. The CFTC and prudential regulators have also adopted mandatory margin requirements for unclearedswaps entered into between swap dealers and certain other counterparties. We currently qualify for and rely upon an end-user exception from such clearingand margin requirements for the swaps we enter into to hedge our commercial risks. However, the application of the mandatory clearing and trade executionrequirements and the uncleared swaps margin requirements to other market participants, such as swap dealers, may adversely affect the cost and availabilityof the swaps that we use for hedging.In addition to the Dodd-Frank Act, the European Union and other foreign regulators have adopted and are implementing local reforms generally comparablewith the reforms under the Dodd-Frank Act. Implementation and enforcement of these regulatory provisions may reduce our ability to hedge our market riskswith non-U.S. counterparties and may make transactions involving cross-border swaps more expensive and burdensome. Additionally, the lack of regulatoryequivalency across jurisdictions may increase compliance costs and make it more difficult to satisfy our regulatory obligations.The NYSE does not require a publicly traded partnership like us to comply with certain corporate governance requirements.Because we are a publicly traded partnership, the NYSE does not require us to have a majority of independent directors on our general partner’s board ofdirectors or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, unitholders do not have the sameprotections afforded to stockholders of corporations that are subject to all of the corporate governance requirements of the applicable stock exchange.A natural disaster, catastrophe or other event could result in severe personal injury, property damage and environmental damage, which could curtail ouroperations and otherwise materially adversely affect our cash flow and, accordingly, affect the market price of our Common Units.Some of our operations involve risks of personal injury, property damage and environmental damage, which could curtail our operations and otherwisematerially adversely affect our cash flow. For example, natural gas pipeline and other facilities operate at high pressures, sometimes in excess of 1,100 poundsper square inch. Virtually all of our operations are exposed to potential natural disasters, including hurricanes, tornadoes, storms, floods and/or earthquakes.If one or more facilities that are owned by us, or that deliver natural gas or other products to us, are damaged by severe weather or any other disaster, accident,catastrophe or event, our operations could be significantly interrupted. Similar interruptions could result from damage to production or other facilities thatsupply our facilities or other stoppages arising from factors beyond our control. These interruptions might involve significant damage to people, property orthe environment, and repairs might take from a week or less for a minor incident to six months or more for a major interruption. Any event that interrupts therevenues generated by our operations, or which causes us to make significant expenditures not covered by insurance, could reduce our cash available forpaying distributions to our Unitholders and, accordingly, adversely affect the market price of our Common Units.As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and in some instances, certain insurancemay become unavailable or available only for reduced amounts of coverage. As a result, we may not be able to renew existing insurance policies or procureother desirable insurance on commercially reasonable terms, if at all. If we were to incur a significant liability for which we were not fully insured, it couldhave a material adverse effect on our financial position and results of operations. In addition, the proceeds of any such insurance may not be paid in a timelymanner and may be insufficient if such an event were to occur.Terrorist attacks aimed at our facilities could adversely affect our business, results of operations, cash flows and financial condition.The United States government has issued warnings that energy assets, including our nation’s pipeline infrastructure, may be the future target of terroristorganizations. Some of our facilities are subject to standards and procedures required by the Chemical Facility Anti-Terrorism Standards. We believe we arein compliance with all material requirements; however, such compliance may not prevent a terrorist attack from causing material damage to our facilities orpipelines. Any such terrorist attack on our facilities or pipelines, those of our customers, or in some cases, those of other pipelines could have a materialadverse effect on our business, financial condition and results of operations.51 Table of ContentsAdditional deepwater drilling laws and regulations, delays in the processing and approval of drilling permits and exploration, development, oil spill-response and decommissioning plans, and other related developments may have a material adverse effect on our business, financial condition, or results ofoperations.The federal Bureau of Ocean Energy Management (“BOEM”) and the federal Bureau of Safety and Environmental Enforcement (“BSEE”), each agencies ofthe United States Department of the Interior, have imposed more stringent permitting procedures and regulatory safety and performance requirements for newwells to be drilled in federal waters. Compliance with these more stringent regulatory requirements and with existing environmental and oil spill regulations,together with any uncertainties or inconsistencies in decisions and rulings by governmental agencies, delays in the processing and approval of drillingpermits or exploration, development, oil spill-response and decommissioning plans, and possible additional regulatory initiatives could result in difficultand more costly actions and adversely affect or delay new drilling and ongoing development efforts.In addition, new regulatory initiatives may be adopted or enforced by the BOEM or the BSEE in the future that could result in additional costs, delays,restrictions, or obligations with respect to oil and natural gas exploration and production operations conducted offshore by certain of our customers. Forexample, in April 2016, the BOEM published a proposed rule that would update existing air-emissions requirements relating to offshore oil and natural-gasactivity on federal Outer Continental Shelf waters. However, in May 2017, Order 3350 was issued by the Department of the Interior Secretary Ryan Zinke,directing the BOEM to reconsider a number of regulatory initiatives governing oil and gas exploration in offshore waters, including, among other things, acessation of all activities to promulgate the April 2016 proposed rulemaking (“Order 3350”). In an unrelated legal initiative, BOEM issued a Notice toLessees and Operators (“NTL #2016-N01”) that became effective in September 2016 and imposes more stringent requirements relating to the provision offinancial assurance to satisfy decommissioning obligations. Together with a recent re-assessment by BSEE in 2016 in how it determines the amount offinancial assurance required, the revised BOEM-administered offshore financial assurance program that is currently being implemented is expected to resultin increased amounts of financial assurance being required of operators on the OCS, which amounts may be significant. However, as directed under Order3350, the BOEM has delayed implementation of NTL #2016-N01 so that it may reconsider this regulatory initiative and, currently, this NTL’simplementation timeline has been extended indefinitely beyond June 30, 2017, except in certain circumstances where there is a substantial risk ofnonperformance of the interest holder’s decommissioning liabilities. The April 2016 proposed rule and NTL #2016-N01, should they be finalized and/orimplemented, as well as any new rules, regulations, or legal initiatives could delay or disrupt our customers operations, increase the risk of expired leases dueto the time required to develop new technology, result in increased supplemental bonding and costs, limit activities in certain areas, or cause our customers’to incur penalties, or shut-in production or lease cancellation. Also, if material spill events were to occur in the future, the United States or other countriescould elect to issue directives to temporarily cease drilling activities offshore and, in any event, may from time to time issue further safety and environmentallaws and regulations regarding offshore oil and gas exploration and development. The overall costs imposed on our customers to implement and completeany such spill response activities or any decommissioning obligations could exceed estimated accruals, insurance limits, or supplemental bonding amounts,which could result in the incurrence of additional costs to complete. We cannot predict with any certainty the full impact of any new laws or regulations onour customers’ drilling operations or on the cost or availability of insurance to cover some or all of the risks associated with such operations. The occurrenceof any one or more of these developments could result in decreased demand for our services, which could have a material adverse effect on our business aswell as our financial position, results of operation and liquidity.Our business is subject to federal, state and local laws and regulations that govern the product quality specifications of the petroleum products that westore and transport.The petroleum products that we store and transport are sold by our customers for consumption into the public market. Various federal, state and localagencies have the authority to prescribe specific product quality specifications to commodities sold into the public market. Changes in product qualityspecifications could reduce our throughput volume, require us to incur additional handling costs or require the expenditure of significant capital. In addition,different product specifications for different markets impact the fungibility of products transported and stored in our pipeline systems and terminal facilitiesand could require the construction of additional storage to segregate products with different specifications. We may be unable to recover these costs throughincreased revenues.In addition, our patented butane blending services are reliant upon gasoline vapor pressure specifications. Significant changes in such specifications couldreduce butane blending opportunities, which would affect our ability to market our butane blending service licenses and which would ultimately affect ourability to recover the costs incurred to acquire and integrate our butane blending assets.Our business could be affected adversely by union disputes and strikes or work stoppages by unionized employees.As of December 31, 2017, approximately 14% of our workforce is covered by a number of collective bargaining agreements with various terms and dates ofexpiration. There can be no assurances that we will not experience a work stoppage in the future as a52 Table of Contentsresult of labor disagreements. Any work stoppage could, depending on the affected operations and the length of the work stoppage, have a material adverseeffect on our business, financial position, results of operations or cash flows.Our operations could be disrupted if our information systems fail, causing increased expenses and loss of sales.Our business is highly dependent on financial, accounting and other data processing systems and other communications and information systems, includingour enterprise resource planning tools. We process a large number of transactions on a daily basis and rely upon the proper functioning of computer systems.If a key system was to fail or experience unscheduled downtime for any reason, even if only for a short period, our operations and financial results could beaffected adversely. Our systems could be damaged or interrupted by a security breach, fire, flood, power loss, telecommunications failure or similar event. Wehave a formal disaster recovery plan in place, but this plan may not entirely prevent delays or other complications that could arise from an informationsystems failure. Our business interruption insurance may not compensate us adequately for losses that may occur.Cybersecurity breaches and other disruptions could compromise our information and operations, and expose us to liability, which would cause ourbusiness and reputation to suffer.In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of ourcustomers, suppliers and business partners, and personally identifiable information of our employees, in our data centers and on our networks. The secureprocessing, maintenance and transmission of this information is critical to our operations and business strategy. Despite our security measures, ourinformation technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Anysuch breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access,disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information,regulatory penalties for divulging shipper information, disruption of our operations, damage to our reputation, and loss of confidence in our products andservices, which could adversely affect our business.Our information technology infrastructure is critical to the efficient operation of our business and essential to our ability to perform day-today operations.Breaches in our information technology infrastructure or physical facilities, or other disruptions, could result in damage to our assets, safety incidents,damage to the environment, potential liability or the loss of contracts, and have a material adverse effect on our operations, financial position and results ofoperations.The costs of providing pension and other postretirement health care benefits and related funding requirements are subject to changes in pension fundvalues, changing demographics and fluctuating actuarial assumptions and may have a material adverse effect on our financial results.Certain of our subsidiaries provide pension plan and other postretirement healthcare benefits to certain of their employees. The costs of providing pensionand other postretirement health care benefits and related funding requirements are subject to changes in pension and other postretirement fund values,changing demographics and fluctuating actuarial assumptions that may have a material adverse effect on the Partnership’s future consolidated financialresults. While certain of the costs incurred in providing such pension and other postretirement healthcare benefits are recovered through the rates charged bythe Partnership’s regulated businesses, the Partnership’s subsidiaries may not recover all of the costs and those rates are generally not immediately responsiveto current market conditions or funding requirements. Additionally, if the current cost recovery mechanisms are changed or eliminated, the impact of thesebenefits on operating results could significantly increase.Our contract compression operations depend on particular suppliers and are vulnerable to parts and equipment shortages and price increases, whichcould have a negative impact on results of operations.The principal manufacturers of components for our natural gas compression equipment include Caterpillar, Inc. for engines, Air-X-Changers for coolers andAriel Corporation for compressors and frames. Our reliance on these suppliers involves several risks, including price increases and a potential inability toobtain an adequate supply of required components in a timely manner. We also rely primarily on two vendors, Spitzer Industries Corp. and StandardEquipment Corp., to package and assemble our compression units. We do not have long-term contracts with these suppliers or packagers, and a partial orcomplete loss of certain of these sources could have a negative impact on our results of operations and could damage our customer relationships.Mergers among customers and competitors could result in lower volumes being shipped on our pipelines or products stored in or distributed through ourterminals, or reduced crude oil marketing margins or volumes.Mergers between existing customers could provide strong economic incentives for the combined entities to utilize their existing systems instead of oursystems in those markets where the systems compete. As a result, we could lose some or all of the volumes and associated revenues from these customers andcould experience difficulty in replacing those lost volumes and revenues, which could materially and adversely affect our results of operations, financialposition, or cash flows.53 Table of ContentsFraudulent activity or misuse of proprietary data involving its outsourcing partners could expose us to additional liability.We utilize both affiliated entities and third parties in the processing of our information and data. Breaches of security measures or the accidental loss,inadvertent disclosure or unapproved dissemination of proprietary information, or sensitive or confidential data about us or our customers, including thepotential loss or disclosure of such information or data as a result of fraud or other forms of deception, could expose us to a risk of loss, or misuse of thisinformation, result in litigation and potential liability, lead to reputational damage, increase our compliance costs, or otherwise harm its business.The liquefaction project is dependent upon securing long-term contractual arrangements for the off-take of LNG on terms sufficient to support thefinancial viability of the projectLCL, an entity whose parent is owned 60% by ETE and 40% by ETP, is in the process of developing a liquefaction project at the site of ETE’s existingregasification facility in Lake Charles, Louisiana. The project development agreement previously entered into in September 2013 with BG Group plc (now"Shell") related to this project expired in February 2017. On June 28, 2017, LCL signed a memorandum of understanding with Korea Gas Corporation andShell to study the feasibility of a joint development of the Lake Charles liquefaction project. The project would utilize existing dock and storage facilitiesowned by ETE located on the Lake Charles site. The parties’ determination as to the feasibility of the project will be particularly dependent upon theprospects for securing long-term contractual arrangements for the off-take of LNG which in turn will be dependent upon supply and demand factors affectingthe price of LNG in foreign markets. The financial viability of the project will also be dependent upon a number of other factors, including the expected costto construct the liquefaction facility, the terms and conditions of the financing for the construction of the liquefaction facility, the cost of the natural gassupply, the costs to transport natural gas to the liquefaction facility, the costs to operate the liquefaction facility and the costs to transport LNG from theliquefaction facility to customers in foreign markets (particularly Europe and Asia). Some of these costs fluctuate based on a variety of factors, includingsupply and demand factors affecting the price of natural gas in the United States, supply and demand factors affecting the costs for construction services forlarge infrastructure projects in the United States, and general economic conditions, there can be no assurance that the parties will determine to proceed todevelop this project.The construction of the liquefaction project remains subject to further approvals and some approvals may be subject to further conditions, review and/orrevocation.While LCL has received authorization from the DOE to export LNG to non-FTA countries, the non-FTA authorization is subject to review, and the DOE mayimpose additional approval and permit requirements in the future or revoke the non-FTA authorization should the DOE conclude that such exportauthorization is inconsistent with the public interest. The failure by LCL to timely maintain the approvals necessary to complete and operate theliquefaction project could have a material adverse effect on its operations and financial condition.Legal actions related to the Dakota Access Pipeline could cause an interruption to operations, which could have an adverse effect on our business andresults of operations.On July 25, 2016, the United States Army Corps of Engineers (“USACE”) issued permits to Dakota Access consistent with environmental and historicpreservation statutes for the pipeline to make two crossings of the Missouri River in North Dakota, including a crossing of the Missouri River at Lake Oahe.The USACE also issued easements to allow the pipeline to cross land owned by the USACE adjacent to the Missouri River in two locations. The StandingRock Sioux Tribe (“SRST”) filed a lawsuit in the United States District Court for the District of Columbia (the “Court”) against the USACE that challengedthe legality of the permits issued for the construction of the Dakota Access pipeline and claimed violations of the National Historic Preservation Act(“NHPA”). Dakota Access intervened in the case.In February 2017, the Department of the Army delivered an easement to Dakota Access allowing the pipeline to cross Lake Oahe. The SRST and CheyenneRiver Sioux Tribe (“CRST”) (which had intervened in the lawsuit brought by SRST), amended their complaints to incorporate religious freedom and otherclaims related to treaties and use of government property. The Oglala and Yankton Sioux tribes, and various individual members, filed related lawsuits inopposition to the Dakota Access pipeline. These lawsuits have been consolidated into the action initiated by the SRST.On June 14, 2017, the Court ruled that the USACE substantially complied with all relevant statutes in connection with the issuance of the permits andeasement, but remanded to the USACE three discrete issues for further analysis and explanation of its prior determination under certain of these statutes. OnOctober 11, 2017, the Court ruled that the pipeline could continue to transport crude oil during the pendency of the remand, but requested briefing from theparties as to whether any conditions on the continued operation of the pipeline during this period. On December 4, 2017, the Court determined to imposethree conditions on continued operation of the pipeline during the remand process. First, Dakota Access must retain an independent auditor to review itscompliance with the conditions and regulations governing its easements and to assess integrity threats to the pipeline. Second, the Court directed DakotaAccess to continue its work with the tribes and the USACE to revise and finalize its response planning54 Table of Contentsfor the section of the pipeline crossing Lake Oahe. Third, the Court directed Dakota Access to submit bi-monthly reports during the remand period disclosingcertain inspection and maintenance information recommended by PHMSA.While we believe that the pending lawsuits are unlikely to adversely affect the continued operation of the pipeline, we cannot assure this outcome. At thistime, we cannot determine when or how these lawsuits will be resolved or the impact they may have on the Dakota Access project.In addition, lawsuits of this nature could result in interruptions to construction or operations of future projects, delays in completing those projects and/orincreased project costs, all of which could have an adverse effect on our business and results of operations.Tax Risks to UnitholdersOur tax treatment depends on our status as a partnership for federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service (“IRS”) were to treat us as a corporation for federal income tax purposes or if webecome subject to a material amount of entity-level taxation for state tax purposes, then our cash available for distribution would be substantiallyreduced.The anticipated after-tax economic benefit of an investment in our Common Units depends largely on our being treated as a partnership for federal incometax purposes. We have not requested, and do not plan to request, a ruling from the IRS, with respect to our classification as a partnership for federal incometax purposes. Despite the fact that we are a limited partnership under Delaware law, we would be treated as a corporation for federal income tax purposesunless we satisfy a “qualifying income” requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement. Failing tomeet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for federal income tax purposes or otherwisesubject us to taxation as an entity.If we were treated as a corporation, we would pay federal income tax at the corporate tax rate, and we would likely pay additional state income taxes atvarying rates. Distributions to Unitholders would generally be taxed again as corporate distributions, and none of our income, gains, losses or deductionswould flow through to Unitholders. Because a tax would then be imposed upon us as a corporation, our cash available for distribution to Unitholders wouldbe substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after-tax return tothe Unitholders, likely causing a substantial reduction in the value of our Common Units.At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise,or other forms of taxation. Imposition of a similar tax on us in the jurisdictions in which we operate or in other jurisdictions to which we may expand couldsubstantially reduce our cash available for distribution to our Unitholders. Our partnership agreement provides that if a law is enacted or existing law ismodified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or localincome tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us.The tax treatment of publicly traded partnerships or an investment in our units could be subject to potential legislative, judicial or administrative changesor differing interpretations, possibly applied on a retroactive basis.The present United States federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modifiedby administrative, legislative or judicial changes or differing interpretations at any time. From time to time, members of Congress propose and considersubstantive changes to the existing United States federal income tax laws that affect publicly traded partnerships. Although there is no current legislativeproposal, a prior legislative proposal would have eliminated the qualifying income exception to the treatment of all publicly traded partnerships ascorporations upon which we rely for our treatment as a partnership for United States federal income tax purposes.In addition, on January 24, 2017, final regulations regarding which activities give rise to qualifying income within the meaning of Section 7704 of theInternal Revenue Code of 1986, as amended (the “Final Regulations”) were published in the Federal Register. The Final Regulations are effective as ofJanuary 19, 2017, and apply to taxable years beginning on or after January 19, 2017. We do not believe the Final Regulations affect our ability to be treatedas a partnership for United States federal income tax purposes.However, any modification to the United States federal income tax laws may be applied retroactively and could make it more difficult or impossible for us tomeet the exception for certain publicly traded partnerships to be treated as partnerships for United States federal income tax purposes. We are unable topredict whether any of these changes or other proposals will ultimately be enacted. Any similar or future legislative changes could negatively impact thevalue of an investment in our common units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrativedevelopments and proposals and their potential effect on your investment in our common units.55 Table of ContentsIf the IRS contests the federal income tax positions we take, the market for our Common Units may be adversely affected and the costs of any such contestwill reduce cash available for distributions to our Unitholders.We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes. The IRS may adopt positions thatdiffer from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A courtmay not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our Common Units andthe prices at which they trade. In addition, the costs of any contest with the IRS will be borne by us reducing the cash available for distribution to ourUnitholders.If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collectany taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us, in which case our cash available fordistribution to our Unitholders might be substantially reduced.Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns,it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us.To the extent possible under the new rules, our general partner may elect to either pay the taxes (including any applicable penalties and interest) directly tothe IRS or, if we are eligible, issue a revised information statement to each Unitholder and former Unitholder with respect to an audited and adjusted return.Although our general partner may elect to have our Unitholders and former Unitholders take such audit adjustment into account and pay any resulting taxes(including applicable penalties or interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that suchelection will be practical, permissible or effective in all circumstances. As a result, our current Unitholders may bear some or all of the tax liability resultingfrom such audit adjustment, even if such Unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, weare required to make payments of taxes, penalties and interest, our cash available for distribution to our Unitholders might be substantially reduced. Theserules are not applicable for tax years beginning on or prior to December 31, 2017.Unitholders may be required to pay taxes on their share of our income even if they do not receive any cash distributions from us.Because our unitholders will be treated as partners to whom we will allocate taxable income which will be different in amount than the cash we distribute, ourunitholders will be required to pay any federal income taxes and, in some cases, state and local income taxes on their share of our taxable income even if theyreceive no cash distributions from us. Our unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal tothe actual tax liability that result from that income.Tax gain or loss on disposition of our Common Units could be more or less than expected.If our unitholders sell their common units, they will recognize a gain or loss equal to the difference between the amount realized and their tax basis in thosecommon units. Prior distributions to our unitholders in excess of the total net taxable income the unitholder was allocated for a unit, which decreased theirtax basis in that unit, will, in effect, become taxable income to our unitholders if the common unit is sold at a price greater than their tax basis in that commonunit, even if the price they receive is less than their original cost. A substantial portion of the amount realized, whether or not representing gain, may beordinary income. In addition, if our unitholders sell their units, they may incur a tax liability in excess of the amount of cash received from the sale.Tax-exempt entities face unique tax issues from owning our units that may result in adverse tax consequences to them.Investment in our units by tax-exempt entities, including employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique tothem. For example, virtually all of our income allocated to Unitholders who are organizations exempt from federal income tax, including IRAs and otherretirement plans, will be “unrelated business taxable income” and will be taxable to them. Further, with respect to taxable years beginning after December 31,2017, a tax-exempt entity with more than one unrelated trade or business (including by attribution from investment in a partnership such as ours that isengaged in one or more unrelated trade or business) is required to compute the unrelated business taxable income of such tax-exempt entity separately withrespect to each such trade or business (including for purposes of determining any net operating loss deduction). As a result, for years beginning afterDecember 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our partnership to offset unrelated business taxableincome from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in our units.56 Table of ContentsNon-United States Unitholders will be subject to United States taxes and withholding with respect to their income and gain from owning our units.Non-United States unitholders are generally taxed and subject to income tax filing requirements by the United States on income effectively connected with aUnited States trade or business (“effectively connected income”). Income allocated to our unitholders and any gain from the sale of our units will generallybe considered to be “effectively connected” with a United States trade or business. As a result, distributions to a Non-United States unitholder will be subjectto withholding at the highest applicable effective tax rate and a Non-United States unitholder who sells or otherwise disposes of a unit will also be subject toUnited States federal income tax on the gain realized from the sale or disposition of that unit. The Tax Cuts and Jobs Act imposes a withholding obligation of 10% of the amount realized upon a Non-United States unitholder’s sale or exchange of aninterest in a partnership that is engaged in a United States trade or business. However, due to challenges of administering a withholding obligation applicableto open market trading and other complications, the IRS has temporarily suspended the application of this withholding rule to open market transfers ofinterests in publicly traded partnerships pending promulgation of regulations or other guidance that resolves the challenges. It is not clear if or when suchregulations or other guidance will be issued. Non-United States unitholders should consult a tax advisor before investing in our units.We have subsidiaries that will be treated as corporations for federal income tax purposes and subject to corporate-level income taxes.Even though we (as a partnership for United States federal income tax purposes) are not subject to United States federal income tax, some of our operationsare currently conducted through subsidiaries that are organized as corporations for United States federal income tax purposes. The taxable income, if any, ofsubsidiaries that are treated as corporations for United States federal income tax purposes, is subject to corporate-level United States federal income taxes,which may reduce the cash available for distribution to us and, in turn, to our Unitholders. If the IRS or other state or local jurisdictions were to successfullyassert that these corporations have more tax liability than we anticipate or legislation was enacted that increased the corporate tax rate, the cash available fordistribution could be further reduced. The income tax return filings positions taken by these corporate subsidiaries require significant judgment, use ofestimates, and the interpretation and application of complex tax laws. Significant judgment is also required in assessing the timing and amounts ofdeductible and taxable items. Despite our belief that the income tax return positions taken by these subsidiaries are fully supportable, certain positions maybe successfully challenged by the IRS, state or local jurisdictions.We treat each purchaser of Common Units as having the same tax benefits without regard to the actual Common Units purchased. The IRS may challengethis treatment, which could result in a Unitholder owing more tax and may adversely affect the value of the Common Units.Because we cannot match transferors and transferees of Common Units and because of other reasons, we have adopted depreciation and amortizationpositions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect theamount of tax benefits available to our Unitholders. It also could affect the timing of these tax benefits or the amount of gain from the sale of Common Unitsand could have a negative impact on the value of our Common Units or result in audit adjustments to tax returns of our Unitholders. Moreover, because wehave subsidiaries that are organized as C corporations for federal income tax purposes which own units in us, a successful IRS challenge could result in thissubsidiary having more tax liability than we anticipate and, therefore, reduce the cash available for distribution to our partnership and, in turn, to ourUnitholders.We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of ourunits on the first business day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge aspects of ourproration method, and, if successful, we would be required to change the allocation of items of income, gain, loss and deduction among our Unitholders.We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership ofour units on the first business day of each month (the “Allocation Date”), instead of on the basis of the date a particular unit is transferred. Similarly, wegenerally allocate certain deductions for depreciation of capital additions, gain or loss realized on a sale or other disposition of our assets and, in thediscretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. TreasuryRegulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of the proration method we haveadopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction amongour Unitholders.57 Table of ContentsA Unitholder whose units are the subject of a securities loan (e.g. a loan to a “short seller”) to cover a short sale of units may be considered as havingdisposed of those units. If so, the Unitholder would no longer be treated for tax purposes as a partner with respect to those units during the period of theloan and may recognize gain or loss from the disposition.Because there are no specific rules governing the federal income tax consequences of loaning a partnership interest, a Unitholder whose units are the subjectof a securities loan may be considered as having disposed of the loaned units. In that case, the Unitholder may no longer be treated for tax purposes as apartner with respect to those units during the period of the loan and may recognize gain or loss from such disposition. Moreover, during the period of theloan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the Unitholder and any cash distributions received bythe Unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gainrecognition from a loan of their units are urged to consult a tax advisor to determine whether it is advisable to modify any applicable brokerage accountagreements to prohibit their brokers from borrowing their units.We have adopted certain valuation methodologies in determining Unitholder’s allocations of income, gain, loss and deduction. The IRS may challengethese methods or the resulting allocations, and such a challenge could adversely affect the value of our common units.When we issue additional units or engage in certain other transactions, we determine the fair market value of our assets and allocate any unrealized gain orloss attributable to such assets to the capital accounts of our unitholders and our general partner. Although we may from time to time consult withprofessional appraisers regarding valuation matters, including the valuation of our assets, we make many of the fair market value estimates of our assetsourselves using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. Our methodologymay be viewed as understating the value of our assets. In that case, there may be a shift of income, gain, loss and deduction between certain unitholders andour general partner, which may be unfavorable to such unitholders. Moreover, under our current valuation methods, subsequent purchasers of our commonunits may have a greater portion of their Internal Revenue Code Section 743(b) adjustment allocated to our tangible assets and a lesser portion allocated toour intangible assets. The IRS may challenge our valuation methods, or our allocation of Section 743(b) adjustment attributable to our tangible andintangible assets, and allocations of income, gain, loss and deduction between our general partner and certain of our unitholders.A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to our unitholders. Italso could affect the amount of gain on the sale of common units by our unitholders and could have a negative impact on the value of our common units orresult in audit adjustments to the tax returns of our unitholders without the benefit of additional deductions.Unitholders will likely be subject to state and local taxes and return filing requirements in states where they do not live as a result of investing in our units.In addition to federal income taxes, the Unitholders may be subject to other taxes, including state and local taxes, unincorporated business taxes and estate,inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if theydo not live in any of those jurisdictions. Unitholders may be required to file state and local income tax returns and pay state and local income taxes in someor all of the jurisdictions. We currently own property or conduct business in many states, most of which impose an income tax on individuals, corporationsand other entities. As we make acquisitions or expand our business, we may control assets or conduct business in additional states that impose a personal orcorporate income tax. Further, Unitholders may be subject to penalties for failure to comply with those requirements. It is the responsibility of eachUnitholder to file all federal, state and local tax returns.Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.In general, our unitholders are entitled to a deduction for the interest we have paid or accrued on indebtedness properly allocable to our trade or businessduring our taxable year. However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, our deduction for “businessinterest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.” For the purposes of this limitation, adjusted taxableincome is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1,2022, any deduction allowable for depreciation, amortization, or depletion. Although the interest limitation does not apply to certain regulated pipelinebusinesses, application of the interest limitation to tiered businesses like ours that hold interests in regulated and unregulated businesses is not clear. Pendingfurther guidance specific to this issue, we have not yet determined the impact the limitation could have on our unitholders’ ability to deduct our interestexpense, but it is possible that our unitholders’ interest expense deduction will be limited.58 Table of ContentsTreatment of distributions on our Series A Preferred Units and Series B Preferred Units as guaranteed payments for the use of capital creates a differenttax treatment for the holders of Series A Preferred Units and Series B Preferred Units than the holders of our common units and such distributions may notbe eligible for the 20% deduction for qualified publicly traded partnership income.The tax treatment of distributions on our Series A Preferred Units and our Series B Preferred Units is uncertain. We will treat each of the holders of the SeriesA Preferred Units and Series B Preferred Units as partners for tax purposes and will treat distributions on the Series A Preferred Units and the Series B PreferredUnits as guaranteed payments for the use of capital that will generally be taxable to each of the holders of Series A Preferred Units and Series B PreferredUnits as ordinary income. Holders of our Series A Preferred Units or Series B Preferred Units will recognize taxable income from the accrual of such aguaranteed payment (even in the absence of a contemporaneous cash distribution). Otherwise, except in the case of our liquidation, the holders of Series APreferred Units and Series B Preferred Units are generally not anticipated to share in our items of income, gain, loss or deduction, nor will we allocate anyshare of our nonrecourse liabilities to the holders of Series A Preferred Units and the Series B Preferred Units. If the Series A Preferred Units and Series BPreferred Units were treated as indebtedness for tax purposes, rather than as guaranteed payments for the use of capital, distributions likely would be treatedas payments of interest by us to each of the holders of Series A Preferred Units and Series B Preferred Units. Although we expect that much of the income we earn is generally eligible for the 20% deduction for qualified publicly traded partnership income, it isuncertain whether a guaranteed payment for the use of capital may constitute an allocable or distributive share of such income. As a result the guaranteedpayment for use of capital received by our Series A Preferred Units and Series B Preferred Units may not be eligible for the 20% deduction for qualifiedpublicly traded partnership income. A holder of Series A Preferred Units or Series B Preferred Units will be required to recognize gain or loss on a sale of Series APreferred Units or Series B Preferred Units, as applicable, equal to the difference between the amount realized by such holder and such holder’s tax basis inthe Series A Preferred Units or Series B Preferred Units, as applicable, sold. The amount realized generally will equal the sum of the cash and the fair marketvalue of other property such holder receives in exchange for such Series A Preferred Units or Series B Preferred Units, as applicable. Subject to general rulesrequiring a blended basis among multiple partnership interests, the tax basis of a Series A Preferred Unit or Series B Preferred Unit, as applicable, willgenerally be equal to the sum of the cash and the fair market value of other property paid by the holder of such Series A Preferred Units or Series B PreferredUnits, as applicable, to acquire such Series A Preferred Unit or Series B Preferred Unit, as applicable. Gain or loss recognized by a holder of Series A PreferredUnits or Series B Preferred Units on the sale or exchange of a Series A Preferred Unit or Series B Preferred Unit, as applicable, held for more than one yeargenerally will be taxable as long-term capital gain or loss. Because holders of Series A Preferred Units and Series B Preferred Units will generally not beallocated a share of our items of depreciation, depletion or amortization, it is not anticipated that such holders would be required to recharacterize anyportion of their gain as ordinary income as a result of the recapture rules. Investment in the Series A Preferred Units or the Series B Preferred Units by tax-exempt investors, such as employee benefit plans and individual retirementaccounts, and non-United States persons raises issues unique to them. The treatment of guaranteed payments for the use of capital to tax-exempt investors isnot certain and such payments may be treated as unrelated business taxable income for federal income tax purposes. Distributions to non-United Statesholders of Series A Preferred Units and Series B Preferred Units will be subject to withholding taxes. If the amount of withholding exceeds the amount ofUnited States federal income tax actually due, non-United States holders of Series A Preferred Units and Series B Preferred Units may be required to fileUnited States federal income tax returns in order to seek a refund of such excess.All holders of our Series A Preferred Units and Series B Preferred Units are urged to consult a tax advisor with respect to the consequences of owning ourSeries A Preferred Units and Series B Preferred Units.ITEM 1B. UNRESOLVED STAFF COMMENTSNone.ITEM 2. PROPERTIESA description of our properties is included in “Item 1. Business.” In addition, we own office buildings for our executive offices in Dallas, Texas and officebuildings in Newton Square, Pennsylvania and Houston, Texas and San Antonio, Texas. While we may require additional office space as our businessexpands, we believe that our existing facilities are adequate to meet our needs for the immediate future, and that additional facilities will be available oncommercially reasonable terms as needed.We believe that we have satisfactory title to or valid rights to use all of our material properties. Although some of our properties are subject to liabilities andleases, liens for taxes not yet due and payable, encumbrances securing payment obligations under59 Table of Contentsnon-competition agreements and immaterial encumbrances, easements and restrictions, we do not believe that any such burdens will materially interfere withour continued use of such properties in our business, taken as a whole. In addition, we believe that we have, or are in the process of obtaining, all requiredmaterial approvals, authorizations, orders, licenses, permits, franchises and consents of, and have obtained or made all required material registrations,qualifications and filings with, the various state and local government and regulatory authorities which relate to ownership of our properties or the operationsof our business.Substantially all of our pipelines, which are described in “Item 1. Business,” are constructed on rights-of-way granted by the apparent record owners of theproperty. Lands over which pipeline rights-of-way have been obtained may be subject to prior liens that have not been subordinated to the right-of-waygrants. We have obtained, where necessary, easement agreements from public authorities and railroad companies to cross over or under, or to lay facilities inor along, watercourses, county roads, municipal streets, railroad properties and state highways, as applicable. In some cases, properties on which our pipelineswere built were purchased in fee. We also own and operate multiple natural gas and NGL storage facilities and own or lease other processing, treating andconditioning facilities in connection with our midstream operations.ITEM 3. LEGAL PROCEEDINGSSunoco, Inc. and/or Sunoco, Inc. (R&M), (now known as Sunoco (R&M), LLC) along with other members of the petroleum industry, are defendants inlawsuits alleging MTBE contamination of groundwater. The plaintiffs, state-level governmental entities, assert product liability claims and additional claimsincluding nuisance, trespass, negligence, violation of environmental laws, and/or deceptive business practices. The plaintiffs seek to recover compensatorydamages, and in some cases also seek natural resource damages, injunctive relief, punitive damages, and attorneys’ fees.As of December 31, 2017, Sunoco, Inc. is a defendant in seven cases, including one case each initiated by the States of Maryland, New Jersey, Vermont,Rhode Island, one by the Commonwealth of Pennsylvania and two by the Commonwealth of Puerto Rico. The more recent Puerto Rico action is a companioncase alleging damages for additional sites beyond those at issue in the initial Puerto Rico action. The actions brought by the State of Maryland andCommonwealth of Pennsylvania have also named as defendants Energy Transfer Partners, L.P., ETP Holdco Corporation, and Sunoco Partners Marketing &Terminals, L.P. Four of these cases are pending in a multidistrict litigation proceeding in a New York federal court; one is pending in federal court in RhodeIsland, one is pending in state court in Vermont, and one is pending in state court in Maryland.Sunoco, Inc. and Sunoco, Inc. (R&M) have reached a settlement with the State of New Jersey. The Court approved the Judicial Consent Order on December 5,2017. Dismissal of the case against Sunoco, Inc. and Sunoco, Inc. (R&M) is expected shortly. The Maryland complaint was filed in December 2017 but wasnot served until January 2018.It is reasonably possible that a loss may be realized in the remaining cases; however, we are unable to estimate the possible loss or range of loss in excess ofamounts accrued. An adverse determination with respect to one or more of the MTBE cases could have a significant impact on results of operations duringthe period in which any such adverse determination occurs, but such an adverse determination likely would not have a material adverse effect on thePartnership’s consolidated financial position.In January 2012, we experienced a release on our products pipeline in Wellington, Ohio. In connection with this release, the PHMSA issued a CorrectiveAction Order under which we are obligated to follow specific requirements in the investigation of the release and the repair and reactivation of the pipeline.This PHMSA Corrective Action Order was closed via correspondence dated November 4, 2016. No civil penalties were associated with the PHMSA Order. Wealso entered into an Order on Consent with the EPA regarding the environmental remediation of the release site. All requirements of the Order on Consentwith the EPA have been fulfilled and the Order has been satisfied and closed. We have also received a “No Further Action” approval from the Ohio EPA forall soil and groundwater remediation requirements. In May 2016, we received a proposed penalty from the EPA and DOJ associated with this release, andcontinues to work with the involved parties to bring this matter to closure. The timing and outcome of this matter cannot be reasonably determined at thistime. However, we do not expect there to be a material impact to our results of operations, cash flows or financial position.In October 2016, the PHMSA issued a Notice of Probable Violation (“NOPVs”) and a Proposed Compliance Order (“PCO”) related to our West Texas Gulfpipeline in connection with repairs being carried out on the pipeline and other administrative and procedural findings. The proposed penalty is in excess of$100,000. The case went to hearing in March 2017 and remains open with PHMSA. We do not expect there to be a material impact to our results ofoperations, cash flows or financial position.In April 2016, the PHMSA issued a NOPV, PCO and Proposed Civil Penalty related to certain procedures carried out during construction of our PermianExpress 2 pipeline system in Texas. The proposed penalties are in excess of $100,000. The case went to Hearing in November 2016 and remains open withPHMSA. We do not expect there to be a material impact to our results of operations, cash flows or financial position.60 Table of ContentsIn July 2016, the PHMSA issued a NOPV and PCO to our West Texas Gulf pipeline in connection with inspection and maintenance activities related to a2013 incident on our crude oil pipeline near Wortham, Texas. The proposed penalties are in excess of $100,000. The case went to hearing in March 2017 andremains open with PHMSA. We do not expect there to be a material impact to our results of operations, cash flows, or financial position.In August 2017, the PHMSA issued a NOPV and a PCO in connection with alleged violations on our Nederland to Kilgore pipeline in Texas. The caseremains open with PHMSA and the proposed penalties are in excess of $100,000. We do not expect there to be a material impact to our results of operations,cash flows or financial position.In December 2016, we received multiple Notice of Violations (“NOVs”) from the Delaware County Regional Water Quality Control Authority (“DELCORA”)in connection with a discharge at our Marcus Hook Industrial Complex (“MHIC”) in July 2016. We also entered in a Consent Order and Agreement from thePennsylvania Department of Environmental Protection (“PADEP”) related to our tank inspection plan at MHIC. These actions propose penalties in excess of$100,000, and we are currently in discussions with the PADEP and DELCORA to resolve these matters. The timing or outcome of these matters cannot bereasonably determined at this time; however, we do not expect there to be a material impact to our results of operations, cash flows, or financial position.The Ohio Environmental Protection Agency (“Ohio EPA”) has alleged that various environmental violations have occurred during construction of the Roverpipeline project. The alleged violations include inadvertent returns of drilling muds and fluids at horizontal directional drilling (“HDD”) locations in Ohiothat affected waters of the State, storm water control violations, improper disposal of spent drilling mud containing diesel fuel residuals, and open burning.The alleged violations occurred from April 2017 to July 2017. Although Rover has successfully completed clean-up mitigation for the alleged violations toOhio EPA’s satisfaction, the Ohio EPA has proposed penalties of approximately $2.6 million in connection with the alleged violations and is seeking certaininjunctive relief. The Ohio Attorney General filed a complaint in the Court of Common Pleas of Stark County, Ohio to obtain these remedies and that caseremains pending and is in the early stages. The timing or outcome of this matter cannot be reasonably determined at this time; however, we do not expectthere to be a material impact to our results of operations, cash flows or financial position.In addition, on May 10, 2017, the FERC prohibited Rover from conducting HDD activities at 27 sites in Ohio. On July 31, 2017, the FERC issued anindependent third party assessment of what led to the release at the Tuscarawas River site and what Rover can do to prevent reoccurrence once the HDDsuspension is lifted. Rover notified the FERC of its intention to implement the suggestions in the assessment and to implement additional voluntaryprotocols. In response, FERC authorized Rover to resume HDD activities at certain sites. On January 24, 2018, FERC ordered Rover to cease HDD activitiesat the Tuscarawas River HDD site pending FERC review of additional information from Rover. Rover continues to correspond with regulators regardingdrilling operations and drilling plans at the HDD sites where Rover has not yet completed HDD activities, including the Tuscarawas River HDD site. Thetiming or outcome of this matter cannot be reasonably determined at this time. We do not expect there to be a material impact to its results of operations, cashflows or financial position.In late 2016, FERC Enforcement Staff began a non-public investigation of Rover’s demolition of the Stoneman House, a potential historic structure, inconnection with Rover’s application for permission to construct a new interstate natural gas pipeline and related facilities. Rover and ETP are cooperatingwith the investigation. In March and April 2017, Enforcement Staff provided Rover its non-public preliminary findings regarding its investigation. Thecompany disagrees with those findings and intends to vigorously defend against any potential penalty. Given the stage of the proceeding, and the non-publicnature of the preliminary findings and investigation, ETP is unable at this time to provide an assessment of the potential outcome or range of potentialliability, if any.On July 25, 2017, the Pennsylvania Environmental Hearing Board (“EHB”) issued an order to SPLP to cease HDD activities in Pennsylvania related to theMariner East 2 project. The EHB issued the order in response to a complaint filed by environmental groups against SPLP and the Pennsylvania Departmentof Environmental Protection (“PADEP”). On August 10, 2017 the parties reached a final settlement requiring that SPLP reevaluate the design parameters ofapproximately 26 drills on the Mariner East 2 project and approximately 43 drills on the Mariner East 2X project. The settlement agreement also provides adefined framework for approval by PADEP for these drills to proceed after reevaluation. Additionally, the settlement agreement requires modifications toseveral of the HDD plans that are part of the PADEP permits. Those modifications have been completed and agreed to by the parties and the reevaluation ofthe drills has been initiated by the company.In addition, on June 27, 2017 and July 25, 2017, the PADEP entered into a Consent Order and Agreement with SPLP regarding inadvertent returns of drillingfluids at three HDD locations in Pennsylvania related to the Mariner East 2 project. Those agreements require SPLP to cease HDD activities at those threelocations until PADEP reauthorizes such activities and to submit a corrective action plan for agency review and approval. SPLP is working to fulfill therequirements of those agreements and has been authorized by PADEP to resume drilling at one of the three locations.61 Table of ContentsOn January 3, 2018, PADEP issued an Administrative Order to Sunoco Pipeline L.P. directing that work on the Mariner East 2 and 2X pipelines be stopped. The Administrative Order detailed alleged violations of the permits issued by PADEP in February of 2017, during the construction of the project. SunocoPipeline L.P. began working with PADEP representatives immediately after the Administrative Order was issued to resolve the compliance issues. Thosecompliance issues could not be fully resolved by the deadline to appeal the Administrative Order, so Sunoco Pipeline L.P. took an appeal of theAdministrative Order to the Pennsylvania Environmental Hearing Board on February 2, 2018. On February 8, 2018, Sunoco Pipeline L.P. entered into aConsent Order and Agreement with PADEP that (1) withdraws the Administrative Order; (2) establishes requirements for compliance with permits on a goingforward basis; (3) resolves the non-compliance alleged in the Administrative Order; and (4) conditions restart of work on an agreement by Sunoco PipelineL.P. to pay a $12.6 million civil penalty to the Commonwealth of Pennsylvania. In the Consent Order and agreement, Sunoco Pipeline L.P. admits to thefactual allegations, but does not admit to the conclusions of law that were made by PADEP. PADEP also found in the Consent Order and Agreement thatSunoco Pipeline L.P. had adequately addressed the issues raised in the Administrative Order and demonstrated an ability to comply with the permits. SunocoPipeline L.P. concurrently filed a request to the Pennsylvania Environmental Hearing Board to discontinue the appeal of the Administrative Order. Thatrequest was granted on February 8, 2018.On January 18, 2018, PHMSA issued a NOPV and a Proposed Civil Penalty in connection with alleged violations on our East Boston jet fuel pipeline inBoston, MA. The case remains open with PHMSA and the proposed penalties are in excess of $100,000. We do not expect there to be a material impact to itsresults of operations, cash flows or financial position.On January 18, PHMSA issued a NOPV and a PCO in connection with alleged violations on Eastern Area refined products and crude oil pipeline system inthe States of MI, OH, PA, NY, NJ and DE. The case remains open with PHMSA and the proposed penalties are in excess of $100,000. We do not expect thereto be a material impact to its results of operations, cash flows or financial position.Additionally, we have received notices of violations and potential fines under various federal, state and local provisions relating to the discharge of materialsinto the environment or protection of the environment. While we believe that even if any one or more of the environmental proceedings listed above weredecided against us, it would not be material to our financial position, results of operations or cash flows, we are required to report governmental proceedingsif we reasonably believe that such proceedings will result in monetary sanctions in excess of $100,000.For a description of other legal proceedings, see Note 11 to our consolidated financial statements included in “Item 8.

Please see “Cash Distribution Policy” below for a discussion of our policyregarding the payment of distributions.Description of UnitsCommon UnitsAs of February 16, 2018, there were approximately 506,829 individual Common Unitholders, which includes Common Units held in street name. TheCommon Units are entitled to distributions of Available Cash as described below under “Cash Distribution Policy.”Class E UnitsThere are currently 8.9 million Class E Units outstanding, all of which are currently owned by HHI. The Class E Units generally do not have any votingrights. The Class E Units are entitled to aggregate cash distributions equal to 11.1% of the total amount of cash distributed to all Unitholders, including theClass E Unitholders, up to $1.41 per unit per year. As the Class E Units are owned by a wholly-owned subsidiary, the cash distributions on those units areeliminated in our consolidated financial statements. Although no plans are currently in place, management may evaluate whether to retire the Class E Units ata future date.Class G UnitsThere are currently 90.7 million Class G Units outstanding, all of which are held by a wholly-owned subsidiary of the Partnership. The Class G Unitsgenerally do not have any voting rights. The Class G Units are entitled to aggregate cash distributions equal to 35% of the total amount of cash generated byus and our subsidiaries, other than ETP Holdco, and available for distribution, up to a maximum of $3.75 per Class G Unit per year. Allocations ofdepreciation and amortization to the Class G Units for tax purposes are based on a predetermined percentage and are not contingent on whether ETP has netincome or loss. These units are reflected as treasury units in the consolidated financial statements.Class I UnitsThe Class I Units are held by ETE and are not currently entitled to any distributions.63 Table of ContentsClass J UnitsOn July 27, 2016, the Partnership issued to ETE an aggregate amount of 180 Class J units representing limited partner interests in the Partnership (the “ClassJ Units”). A portion of the additional Class J Units will be issued during each of 2016, 2017 and 2018. Each Class J Unit is entitled to an allocation of $10.0million of depreciation, amortization, depletion or other form of cost-recovery during the year in which such Class J Unit was issued; no Class J Unit isentitled to any other allocations of depreciation, amortization, depletion or other cost-recovery in any other year, and such units are not entitled to any cashdistributions at any time. In exchange for the issuance of the Class J Units, ETP’s partnership agreement was amended to further reduce incentivedistributions commencing with the quarter ended June 30, 2016 and ending with the quarter ending December 31, 2017, in an aggregate amount of$720 million.Class K UnitsOn December 29, 2016, the Partnership issued to certain of its indirect subsidiaries, in exchange for cash contributions and the exchange of outstandingcommon units representing limited partner interests in the Partnership, Class K Units, each of which is entitled to a quarterly cash distribution of $0.67275per Class K Unit prior to ETP making distributions of available cash to any class of units, excluding any cash available distributions or dividends or capitalstock sales proceeds received by ETP from ETP Holdco. If the Partnership is unable to pay the Class K Unit quarterly distribution with respect to any quarter,the accrued and unpaid distributions will accumulate until paid and any accumulated balance will accrue 1.5% per annum until paid. As of December 31,2017, a total of 101.5 million Class K Units were held by wholly-owned subsidiaries of ETP.General Partner InterestAs of December 31, 2017, our General Partner owned an approximate 0.3% general partner interest in us and the holders of Common Units, Class E, Class G,Class I, Class J, and Class K Units collectively owned a 99.7% limited partner interest in us.Incentive Distribution RightsIDRs represent the contractual right, pursuant to the terms of our partnership agreement, of our general partner to receive a specified percentage of quarterlydistributions of Available Cash from operating surplus after the minimum quarterly distribution has been paid. Please read “Distributions of Available Cashfrom Operating Surplus” below.ETP Preferred UnitsIn November 2017, ETP issued 950,000 of its 6.250% Series A Preferred Units at a price of $1,000 per unit, and 550,000 of its 6.625% Series B PreferredUnits at a price of $1,000 per unit.Distributions on the Series A Preferred Units will accrue and be cumulative from and including the date of original issue to, but excluding, February 15, 2023,at a rate of 6.250% per annum of the stated liquidation preference of $1,000. On and after February 15, 2023, distributions on the Series A Preferred Units willaccumulate at a percentage of the $1,000 liquidation preference equal to an annual floating rate of the three-month LIBOR, determined quarterly, plus aspread of 4.028% per annum. The Series A Preferred Units are redeemable at ETP’s option on or after February 15, 2023 at a redemption price of $1,000 perSeries A Preferred Unit, plus an amount equal to all accumulated and unpaid distributions thereon to, but excluding, the date of redemption.Distributions on the Series B Preferred Units will accrue and be cumulative from and including the date of original issue to, but excluding, February 15, 2028,at a rate of 6.625% per annum of the stated liquidation preference of $1,000. On and after February 15, 2028, distributions on the Series B Preferred Units willaccumulate at a percentage of the $1,000 liquidation preference equal to an annual floating rate of the three-month LIBOR, determined quarterly, plus aspread of 4.155% per annum. The Series B Preferred Units are redeemable at ETP’s option on or after February 15, 2028 at a redemption price of $1,000 perSeries B Preferred Unit, plus an amount equal to all accumulated and unpaid distributions thereon to, but excluding, the date of redemption.Cash Distribution PolicyGeneral. We will distribute all of our “Available Cash” to our Unitholders and our General Partner within 45 days following the end of each fiscal quarter.Definition of Available Cash. Available Cash is defined in our Partnership Agreement and generally means, with respect to any calendar quarter, all cash onhand at the end of such quarter:•Less the amount of cash reserves that are necessary or appropriate in the reasonable discretion of the General Partner to:•provide for the proper conduct of our business;64 Table of Contents•comply with applicable law and/or debt instrument or other agreement (including reserves for future capital expenditures and for our future capitalneeds); or•provide funds for distributions to Unitholders and our General Partner in respect of any one or more of the next four quarters.•Plus all cash on hand on the date of determination of Available Cash for the quarter resulting from working capital borrowings made after the end of thequarter. Working capital borrowings are generally borrowings that are made under our credit facilities and in all cases used solely for working capitalpurposes or to pay distributions to partners.Available Cash is more fully defined in our Partnership Agreement, which is an exhibit to this report.Operating Surplus and Capital SurplusGeneral. All cash distributed to our Unitholders is characterized as either “operating surplus” or “capital surplus.” We distribute available cash fromoperating surplus differently than available cash from capital surplus.Definition of Operating Surplus. Our operating surplus for any period generally means:•our cash balance on the closing date of our initial public offering; plus•$15 million (as described below); plus•all of our cash receipts since the closing of our initial public offering, excluding cash from interim capital transactions such as borrowings that are notworking capital borrowings, sales of equity and debt securities and sales or other dispositions of assets outside the ordinary course of business; plus•our working capital borrowings made after the end of a quarter but before the date of determination of operating surplus for the quarter; plus•legacy ETP’s operating surplus at the time of closing of the merger between legacy ETP and the Partnership in April 2017; less•all of our operating expenditures after the closing of our initial public offering, including the repayment of working capital borrowings, but not therepayment of other borrowings, and including maintenance capital expenditures; less•the amount of our cash reserves that our General Partner deems necessary or advisable to provide funds for future operating expenditures.Definition of Capital Surplus. Generally, our capital surplus will be generated only by:•borrowings other than working capital borrowings;•sales of our debt and equity securities; and•sales or other disposition of assets for cash, other than inventory, accounts receivable and other current assets sold in the ordinary course of business or aspart of normal retirements or replacements of assets.Characterization of Cash Distributions. We will treat all Available Cash distributed as coming from operating surplus until the sum of all Available Cashdistributed since we began operations equals the operating surplus as of the most recent date of determination of Available Cash. We will treat any amountdistributed in excess of operating surplus, regardless of its source, as capital surplus. As defined in our Partnership Agreement, operating surplus includes $25million (consisting of $15 million related to the legacy Sunoco Logistics operating surplus and $10 million related to the legacy ETP operating surplus) inaddition to our cash balance on the closing date of our initial public offering, cash receipts from our operations and cash from working capital borrowings.This amount does not reflect actual cash on hand that is available for distribution to our Unitholders. Rather, it is a provision that enables us, if we choose, todistribute as operating surplus up to $25 million of cash we receive in the future from non-operating sources, such as asset sales, issuances of securities, andlong-term borrowings, that would otherwise be distributed as capital surplus. We have not made, and we anticipate that we will not make, any distributionsfrom capital surplus.65 Table of ContentsDistributions of Available Cash from Operating SurplusThe terms of our partnership agreement require that we make cash distributions with respect to each calendar quarter within 45 days following the end of eachcalendar quarter. As discussed above under “Description of Units – Class K Units” and “Description of Units – ETP Preferred Units,” the Class K Units, theSeries A Preferred Units and the Series B Preferred Units are entitled to distributions from ETP prior to ETP making quarterly distributions of Available Cashto other classes of units. We are required to make distributions of remaining Available Cash from operating surplus for any quarter in the following manner:•First, 100% to all Common Unitholders, Class E Unitholders and Class G Unitholders and the general partner, in accordance with their percentageinterests, until each Common Unit has received $0.075 per unit for such quarter (the “minimum quarterly distribution”);•Second, 100% to all Common Unitholders, Class E Unitholders and Class G Unitholders and the general partner, in accordance with their respectivepercentage interests, until each Common Unit has received $0.0833 per unit for such quarter (the “first target distribution”);•Third, (i) to the general partner in accordance with its percentage interest, (ii) 13% to the holders of the IDRs, pro rata, and (iii) to all CommonUnitholders, Class E Unitholders and Class G Unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner andholders of the IDRs, until each Common Unit has received $0.0958 per unit for such quarter (the “second target distribution”);•Fourth, (i) to the general partner in accordance with its percentage interest, (ii) 35% to the holders of the IDRs, pro rata, and (iii) to all CommonUnitholders, Class E Unitholders and Class G Unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner andholders of the IDRs, until each Common Unit has received $0.2638 per unit for such quarter (the “third target distribution”); and•Fifth, thereafter, (i) to the general partner in accordance with its percentage interest, (ii) 48% to the holder of the IDRs, pro rata, and (iii) to all CommonUnitholders, Class E Unitholders and Class G Unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner andholders of the IDRs.The allocation of distributions among the Common, Class E and Class G Unitholders and the General Partner is based on their respective interests as of therecord date for such distributions.Notwithstanding the foregoing, the distributions on each Class E unit may not exceed $1.41 per year and distributions on each Class G unit may not exceed$3.75 per year. In addition, the distributions to the holders of the incentive distribution rights will not exceed the amount the holders of the incentivedistributions rights would otherwise receive if the available cash for distribution were reduced to the extent it constitutes amounts previously distributed withrespect to the Class G units.The incentive distributions described above do not reflect the impact of IDR subsidies previously agreed to by ETE in connection with previous transactions,as described below under “IDR Subsidies.”Distributions of Available Cash from Capital SurplusWe will make distributions of any Available Cash from capital surplus in the following manner:•First, to all of our Unitholders and to our General Partner, in accordance with their percentage interests, until we distribute for each Common Unit, anamount of available cash from capital surplus equal to our initial public offering price; and•Thereafter, we will make all distributions of Available Cash from capital surplus as if they were from operating surplus.Our Partnership Agreement treats a distribution of capital surplus as the repayment of the initial unit price from the initial public offering, which is a return ofcapital. The initial public offering price per Common Unit less any distributions of capital surplus per unit is referred to as the “unrecovered capital.”If we combine our units into fewer units or subdivide our units into a greater number of units, we will proportionately adjust our minimum quarterlydistribution; our target cash distribution levels; and our unrecovered capital. For example, if a two-for-one split of our Common Units should occur, ourunrecovered capital would be reduced to 50% of the initial level. We will not make any adjustment by reason of our issuance of additional units for cash orproperty.In addition, if legislation is enacted or if existing law is modified or interpreted in a manner that causes us to become taxable as a corporation or otherwisesubject to additional taxation as an entity for federal, state or local income tax purposes, under the terms of the Partnership Agreement, we can reduce ourminimum quarterly distribution and the target cash distribution levels by multiplying the same by one minus the sum of the highest marginal federalcorporate income tax rate that could apply and any increase in the effective overall state and local income tax rates.66 Table of ContentsIDR Subsidies and Other Distribution AdjustmentsAs described above, our partnership agreement requires certain incentive distributions to the holders of the IDRs.In connection with previous transactions, ETE has agreed to relinquish its right to the following amounts of incentive distributions in future periods: Total Year2018 $1532019 128Each year beyond 2019 33Recent Sales of Unregistered SecuritiesNone.Issuer Purchases of Equity SecuritiesNone.Securities Authorized for Issuance Under Equity Compensation PlansFor information on the securities authorized for issuance under ETP’s equity compensation plans, see “Item 12.

Management’s Discussion and Analysis of Financial Condition and Results ofOperations” and the historical consolidated financial statements and the accompanying notes thereto included elsewhere in this report. The amounts in thetable below, except per unit data, are in millions.As discussed in Note 1 to the consolidated financial statements in “Item 8. Financial Statements and Supplementary Data” the merger of legacy ETP andlegacy Sunoco Logistics in April 2017 resulted in legacy ETP being treated as the surviving entity from an accounting perspective. Accordingly, the selectedfinancial data below reflects the consolidated financial information of legacy ETP, except otherwise noted.The historical common units, cash distributions per unit and net income (loss) per limited partner unit amounts presented in these consolidated financialstatements have been retrospectively adjusted to reflect the 1.5 to one unit-for-unit exchange in connection with the Sunoco Logistics Merger.As discussed in Note 2 to the Partnership’s consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data,” in thefourth quarter of 2017, the Partnership changed its accounting policy related to certain inventories. Certain crude oil, refined product and NGL inventorieswere changed from last-in, first-out (“LIFO”) method to the weighted average cost method. These changes have been applied retrospectively to all periodspresented, and the prior period amounts reflected below have been adjusted from those amounts previously reported.67 Table of Contents Years Ended December 31, 2017 2016* 2015* 2014* 2013*Statement of Operations Data: Total revenues$29,054 $21,827 $34,292 $55,475 $48,335Operating income2,397 1,761 2,227 2,393 1,655Income from continuing operations2,501 583 1,489 1,185 749Net income (loss) per Common Unit0.94 (1.38) (0.07) 1.16 (0.10)Diluted net income (loss) per Common Unit0.93 (1.38) (0.08) 1.15 (0.10)Cash distributions per common unit (1)2.22 2.02 1.79 1.50 1.23Cash distributions per common unit - LegacyETP (2)N/A 2.81 2.77 2.57 2.41Balance Sheet Data (at period end): Total assets77,965 70,105 65,128 62,505 49,937Long-term debt, less current maturities32,687 31,741 28,553 24,831 19,761Total equity34,151 26,441 26,986 25,298 18,731Other Financial Data: Capital expenditures: Maintenance (accrual basis)429 368 485 444 391Growth (accrual basis)5,472 5,442 7,682 5,050 2,936Cash paid for acquisitions264 1,227 804 2,367 1,737* As adjusted for the change in accounting policy related to inventory valuation, as discussed above.(1) Represents cash distributions of legacy Sunoco Logistics through the closing of the Sunoco Logistics Merger and ETP thereafter.(2) Represents cash distributions on legacy ETP common units through the closing of the Sunoco Logistics Merger.68 Table of ContentsITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONAND RESULTS OF OPERATIONS(Tabular dollar and unit amounts, except per unit data, are in millions)The following is a discussion of our historical consolidated financial condition and results of operations, and should be read in conjunction with ourhistorical consolidated financial statements and accompanying notes thereto included in “Item 8. Financial Statements and Supplementary Data” of thisreport. This discussion includes forward-looking statements that are subject to risk and uncertainties. Actual results may differ substantially from thestatements we make in this section due to a number of factors that are discussed in “Item 1A. Risk Factors” included in this report.References to “we,” “us,” “our,” the “Partnership” and “ETP” shall mean Energy Transfer Partners, L.P. and its subsidiaries.OverviewThe primary activities and operating subsidiaries through which we conduct those activities are as follows:•Natural gas operations, including the following:•natural gas midstream and intrastate transportation and storage; and•interstate natural gas transportation and storage.•Crude oil, NGLs and refined product transportation, terminalling services and acquisition and marketing activities, as well as NGL storage andfractionation services.Recent DevelopmentsJanuary 2018 Sunoco LP Common Units RepurchaseIn February 2018, after the record date for Sunoco LP’s fourth quarter 2017 cash distributions, Sunoco LP repurchased 17,286,859 Sunoco LP common unitsowned by ETP for aggregate cash consideration of approximately $540 million. ETP used the proceeds from the sale of the Sunoco LP common units to repayamounts outstanding under its revolving credit facility.CDM Contribution AgreementIn January 2018, ETP entered into a contribution agreement (“CDM Contribution Agreement”) with ETP GP, ETC Compression, LLC, USAC and ETE,pursuant to which, among other things, ETP will contribute to USAC and USAC will acquire from ETP all of the issued and outstanding membership interestsof CDM and CDM E&T for aggregate consideration of approximately $1.7 billion, consisting of (i) 19,191,351 common units representing limited partnerinterests in USAC (“USAC Common Units”), with a value of approximately $335 million, (ii) 6,397,965 units of a newly authorized and established class ofunits representing limited partner interests in USAC (“Class B Units”), with a value of approximately $112 million and (iii) an amount in cash equal to$1.225 billion, subject to certain adjustments. The Class B Units that ETP will receive will be a new class of partnership interests of USAC that will havesubstantially all of the rights and obligations of a USAC Common Unit, except the Class B Units will not participate in distributions made prior to the oneyear anniversary of the closing date of the CDM Contribution Agreement (such date, the “Class B Conversion Date”) with respect to USAC Common Units.On the Class B Conversion Date, each Class B Unit will automatically convert into one USAC Common Unit. The transaction is expected to close in the firsthalf of 2018, subject to customary closing conditions.In connection with the CDM Contribution Agreement, ETP entered into a purchase agreement with ETE, Energy Transfer Partners, L.L.C. (together with ETE,the “GP Purchasers”), USAC Holdings and, solely for certain purposes therein, R/C IV USACP Holdings, L.P., pursuant to which, among other things, the GPPurchasers will acquire from USAC Holdings (i) all of the outstanding limited liability company interests in USA Compression GP, LLC, the general partnerof USAC (“USAC GP”), and (ii) 12,466,912 USAC Common Units for cash consideration equal to $250 million.ETP Credit FacilitiesOn December 1, 2017 the Partnership entered into a five-year, $4.0 billion unsecured revolving credit facility, which matures December 1, 2022 (the “ETPFive-Year Facility”) and a $1.0 billion 364-day revolving credit facility that matures on November 30, 2018 (the “ETP 364-Day Facility”) (collectively, the“ETP Credit Facilities”).ETP Preferred UnitsIn November 2017, ETP issued 950,000 of its 6.250% Series A Preferred Units at a price of $1,000 per unit, and 550,000 of its 6.625% Series B PreferredUnits at a price of $1,000 per unit. See additional information included in “Description of Units – ETP69 Table of ContentsPreferred Units” in “Item 5. Market for Registrant’s Common Units, Related Unitholder Matters and Issuer Purchases of Equity Securities.”ETP Senior Notes Offering In September 2017, Sunoco Logistics Partners Operations L.P., a subsidiary of ETP, issued $750 million aggregate principal amount of 4.00% senior notesdue 2027 and $1.50 billion aggregate principal amount of 5.40% senior notes due 2047. The $2.22 billion net proceeds from the offering were used toredeem all of the $500 million aggregate principal amount of ETLP’s 6.5% senior notes due 2021, to repay borrowings outstanding under the SunocoLogistics Credit Facility and for general partnership purposes.August 2017 Units OfferingIn August 2017, the Partnership issued 54 million ETP common units in an underwritten public offering. Net proceeds of $997 million from the offering wereused by the Partnership to repay amounts outstanding under its revolving credit facilities, to fund capital expenditures and for general partnership purposes.Rover Contribution AgreementIn October 2017, ETP completed the previously announced contribution transaction with a fund managed by Blackstone Energy Partners and BlackstoneCapital Partners, pursuant to which ETP exchanged a 49.9% interest in the holding company that owns 65% of the Rover pipeline (“Rover Holdco”). As aresult, Rover Holdco is now owned 50.1% by ETP and 49.9% by Blackstone. Upon closing, Blackstone contributed funds to reimburse ETP for its pro ratashare of the Rover construction costs incurred by ETP through the closing date, along with the payment of additional amounts subject to certain adjustments.PennTex Tender Offer and Limited Call Right ExerciseIn June 2017, ETP purchased all of the outstanding PennTex common units not previously owned by ETP for $20.00 per common unit in cash. ETP nowowns all of the economic interests of PennTex, and PennTex common units are no longer publicly traded or listed on the NASDAQ.ETP and Sunoco Logistics MergerIn April 2017, Energy Transfer Partners, L.P. and Sunoco Logistics completed a merger transaction (the “Sunoco Logistics Merger”) in which SunocoLogistics acquired Energy Transfer Partners, L.P. in a unit-for-unit transaction, with the Energy Transfer Partners, L.P. unitholders receiving 1.5 common unitsof Sunoco Logistics for each Energy Transfer Partners, L.P. common unit they owned. Under the terms of the merger agreement, Sunoco Logistics’ generalpartner was merged with and into ETP GP, with ETP GP surviving as an indirect wholly-owned subsidiary of ETE.Permian Express PartnersIn February 2017, Sunoco Logistics formed PEP, a strategic joint venture with ExxonMobil. Sunoco Logistics contributed its Permian Express 1, PermianExpress 2, Permian Longview and Louisiana Access pipelines. ExxonMobil contributed its Longview to Louisiana and Pegasus pipelines, Hawkins gatheringsystem, an idle pipeline in southern Oklahoma, and its Patoka, Illinois terminal. Assets contributed to PEP by ExxonMobil were reflected at fair value on thePartnership’s consolidated balance sheet at the date of the contribution, including $547 million of intangible assets and $435 million of property, plant andequipment.In July 2017, ETP contributed an approximate 15% ownership interest in Dakota Access and ETCO to PEP, which resulted in an increase in ETP’s ownershipinterest in PEP to approximately 88%. ETP maintains a controlling financial and voting interest in PEP and is the operator of all of the assets. As such, PEP isreflected as a consolidated subsidiary of the Partnership. ExxonMobil’s interest in PEP is reflected as noncontrolling interest in the consolidated balancesheets. ExxonMobil’s contribution resulted in an increase of $988 million in noncontrolling interest, which is reflected in “Capital contributions fromnoncontrolling interest” in the consolidated statement of equity.Bakken Equity SaleIn February 2017, Bakken Holdings Company LLC, an entity in which ETP indirectly owns a 100% membership interest, sold a 49% interest in its wholly-owned subsidiary, Bakken Pipeline Investments LLC, to MarEn Bakken Company LLC, an entity jointly owned by MPLX LP and Enbridge Energy Partners,L.P., for $2.00 billion in cash. Bakken Pipeline Investments LLC indirectly owns a 75% interest in each of Dakota Access and ETCO. The remaining 25% ofeach of Dakota Access and ETCO is owned by wholly-owned subsidiaries of Phillips 66. ETP continues to consolidate Dakota Access and ETCO subsequentto this transaction.70 Table of ContentsGeneralOur primary objective is to increase the level of our distributable cash flow to our Unitholders over time by pursuing a business strategy that is focused ongrowing our businesses through, among other things, pursuing construction and expansion opportunities and acquiring strategic operations and businesses orassets as demonstrated by our recent acquisitions and organic growth projects. The actual amounts of cash that we will have available for distribution willprimarily depend on the amount of cash we generate from our operations.During the past several years, we have been successful in completing several transactions that have significantly increased our distributable cash flow. Wehave also made, and are continuing to make, significant investments in internal growth projects, primarily the construction of pipelines, gathering systemsand natural gas treating and processing plants, which we believe will provide additional distributable cash flow to our Partnership for years to come. Lastly,we have established and executed on cost control measures to drive cost savings across our operations to generate additional distributable cash flow.Our principal operations as of December 31, 2017 included the following segments:•Intrastate transportation and storage – Revenue is principally generated from fees charged to customers to reserve firm capacity on or move gas throughour pipelines on an interruptible basis. Our interruptible or short-term business is generally impacted by basis differentials between delivery points onour system and the price of natural gas. The basis differentials that primarily impact our interruptible business are primarily among receipt pointsbetween West Texas to East Texas or segments thereof. When narrow or flat spreads exist, our open capacity may be underutilized and go unsold.Conversely, when basis differentials widen, our interruptible volumes and fees generally increase. The fee structure normally consists of a monetary feeand fuel retention. Excess fuel retained after consumption, if any, is typically sold at market prices. In addition to transport fees, we generate revenuefrom purchasing natural gas and transporting it across our system. The natural gas is then sold to electric utilities, independent power plants, localdistribution companies, industrial end-users and other marketing companies. The HPL System purchases natural gas at the wellhead for transport andselling. Other pipelines with access to West Texas supply, such as Oasis and ET Fuel, may also purchase gas at the wellhead and other supply sources fortransport across our system to be sold at market on the east side of our system. This activity allows our intrastate transportation and storage segment tocapture the current basis differentials between delivery points on our system or to capture basis differentials that were previously locked in throughhedges. Firm capacity long-term contracts are typically not subject to price differentials between shipping locations.We also generate fee-based revenue from our natural gas storage facilities by contracting with third parties for their use of our storage capacity. From timeto time, we inject and hold natural gas in our Bammel storage facility to take advantage of contango markets, a term used to describe a pricingenvironment when the price of natural gas is higher in the future than the current spot price. We use financial derivatives to hedge the natural gas held inconnection with these arbitrage opportunities. Our earnings from natural gas storage we purchase, store and sell are subject to the current market prices(spot price in relation to forward price) at the time the storage gas is hedged. At the inception of the hedge, we lock in a margin by purchasing gas in thespot market and entering into a financial derivative to lock in the forward sale price. If we designate the related financial derivative as a fair value hedgefor accounting purposes, we value the hedged natural gas inventory at current spot market prices whereas the financial derivative is valued using forwardnatural gas prices. As a result of fair value hedge accounting, we have elected to exclude the spot forward premium from the measurement of effectivenessand changes in the spread between forward natural gas prices and spot market prices result in unrealized gains or losses until the underlying physical gasis withdrawn and the related financial derivatives are settled. Once the gas is withdrawn and the designated derivatives are settled, the previouslyunrealized gains or losses associated with these positions are realized. If the spread narrows between spot and forward prices, we will record unrealizedgains or lower unrealized losses. If the spread widens prior to withdrawal of the gas, we will record unrealized losses or lower unrealized gains.As noted above, any excess retained fuel is sold at market prices. To mitigate commodity price exposure, we may use financial derivatives to hedgeprices on a portion of natural gas volumes retained. For certain contracts that qualify for hedge accounting, we designate them as cash flow hedges of theforecasted sale of gas. The change in value, to the extent the contracts are effective, remains in accumulated other comprehensive income until theforecasted transaction occurs. When the forecasted transaction occurs, any gain or loss associated with the derivative is recorded in cost of products soldin the consolidated statement of operations.In addition, we use financial derivatives to lock in price differentials between market hubs connected to our assets on a portion of our intrastatetransportation system’s unreserved capacity. Gains and losses on these financial derivatives are dependent on price differentials at market locations,primarily points in West Texas and East Texas. We account for these derivatives using mark-to-market accounting, and the change in the value of thesederivatives is recorded in earnings. During the fourth quarter of 2011, we began using derivatives for trading purposes.71 Table of Contents•Interstate transportation and storage – The majority of our interstate transportation and storage revenues are generated through firm reservation chargesthat are based on the amount of firm capacity reserved for our firm shippers regardless of usage. Tiger, FEP, Transwestern, Panhandle, MEP and GulfStates shippers have made long-term commitments to pay reservation charges for the firm capacity reserved for their use. In addition to reservationrevenues, additional revenue sources include interruptible transportation charges as well as usage rates and overrun rates paid by firm shippers based ontheir actual capacity usage.•Midstream – Revenue is principally dependent upon the volumes of natural gas gathered, compressed, treated, processed, purchased and sold throughour pipelines as well as the level of natural gas and NGL prices.In addition to fee-based contracts for gathering, treating and processing, we also have percent-of-proceeds and keep-whole contracts, which are subject tomarket pricing. For percent-of-proceeds contracts, we retain a portion of the natural gas and NGLs processed, or a portion of the proceeds of the sales ofthose commodities, as a fee. When natural gas and NGL prices increase, the value of the portion we retain as a fee increases. Conversely, when prices ofnatural gas and NGLs decrease, so does the value of the portion we retain as a fee. For wellhead (keep-whole) contracts, we retain the difference betweenthe price of NGLs and the cost of the gas to process the NGLs. In periods of high NGL prices relative to natural gas, our margins increase. During periodsof low NGL prices relative to natural gas, our margins decrease or could become negative. Our processing contracts and wellhead purchases in richnatural gas areas provide that we earn and take title to specified volumes of NGLs, which we also refer to as equity NGLs. Equity NGLs in our midstreamsegment are derived from performing a service in a percent-of-proceeds contract or produced under a keep-whole arrangement.In addition to NGL price risk, our processing activity is also subject to price risk from natural gas because, in order to process the gas, in some cases wemust purchase it. Therefore, lower gas prices generally result in higher processing margins.•NGL and refined products transportation and services – Liquids transportation revenue is principally generated from fees charged to customers underdedicated contracts or take-or-pay contracts. Under a dedicated contract, the customer agrees to deliver the total output from particular processing plantsthat are connected to the NGL pipeline. Take-or-pay contracts have minimum throughput commitments requiring the customer to pay regardless ofwhether a fixed volume is transported. Transportation fees are market-based, negotiated with customers and competitive with regional regulatedpipelines.NGL storage revenues are derived from base storage fees and throughput fees. Base storage fees are based on the volume of capacity reserved, regardlessof the capacity actually used. Throughput fees are charged for providing ancillary services, including receipt and delivery, custody transfer, rail/truckloading and unloading fees. Storage contracts may be for dedicated storage or fungible storage. Dedicated storage enables a customer to reserve an entirestorage cavern, which allows the customer to inject and withdraw proprietary and often unique products. Fungible storage allows a customer to storespecified quantities of NGL products that are commingled in a storage cavern with other customers’ products of the same type and grade. NGL storagecontracts may be entered into on a firm or interruptible basis. Under a firm basis contract, the customer obtains the right to store products in the storagecaverns throughout the term of the contract; whereas, under an interruptible basis contract, the customer receives only limited assurance regarding theavailability of capacity in the storage caverns. Revenues are also generated by charging fees for terminalling services for NGLs and refined products andby acquiring and marketing NGLs and refined products. Generally, NGL and refined products purchases are entered into in contemplation of orsimultaneously with corresponding sale transactions involving physical deliveries, which enables us to secure a profit on the transaction at the time ofpurchase.Our refined products terminals derive revenues from terminalling fees paid by customers. A fee is charged for receiving products into the terminal anddelivering them to trucks, barges, or pipelines. In addition to terminalling fees, our refined products terminals generate revenues by charging customersfees for blending services, including certain ethanol and biodiesel blending, injecting additives, and filtering jet fuel. Our refined products pipelinesprovide supply to the majority of our refined products terminals, with third-party pipelines and barges supplying the remainder.Our refined products acquisition and marketing activities include the acquisition, marketing and selling of bulk refined products such as gasolineproducts and distillates. These activities utilize our refined products pipeline and terminal assets, as well as third-party assets and facilities. Theoperating results of our refined products acquisition and marketing activities are dependent on our ability to execute sales in excess of the aggregatecost, and therefore we structure our acquisition and marketing operations to optimize the sources and timing of purchases and minimize thetransportation and storage costs. In order to manage exposure to volatility in refined products prices, our policy is to (i) only purchase products for whichsales contracts have been executed or for which ready markets exist, (ii) structure sales contracts so that price fluctuations do not materially impact themargins earned, and (iii) not acquire and hold physical inventory, futures contracts or other derivative instruments for the purpose of speculating oncommodity price changes. However, we do utilize a hedge program involving swaps, future and other derivative instruments to mitigate the riskassociated with unfavorable market movements in the price of refined products. These derivative contracts act as a hedging mechanism against thevolatility of prices.72 Table of ContentsThis segment also includes revenues earned from processing and fractionating refinery off-gas. Under these contracts we receive an O-grade stream fromcryogenic processing plants located at refineries and fractionate the products into their pure components. We deliver purity products to customersthrough pipelines and across a truck rack located at the fractionation complex. In addition to revenues for fractionating the O-grade stream, we havepercentage-of-proceeds and income sharing contracts, which are subject to market pricing of olefins and NGLs. For percentage-of-proceeds contracts, weretain a portion of the purity NGLs and olefins processed, or a portion of the proceeds from the sales of those commodities, as a fee. When NGLs andolefin prices increase, the value of the portion we retain as a fee increases. Conversely, when NGLs and olefin prices decrease, so does the value of theportion we retain as a fee. Under our income sharing contracts, we pay the producer the equivalent energy value for their liquids, similar to a traditionalkeep-whole processing agreement, and then share in the residual income created by the difference between NGLs and olefin prices as compared to naturalgas prices. As NGLs and olefins prices increase in relation to natural gas prices, the value of the percent we retain as a fee increases. Conversely, whenNGLs and olefins prices decrease as compared to natural gas prices, so does the value of the percent we retain as a fee.•Crude oil transportation and services – Revenues are generated by charging tariffs for transporting crude oil though our pipelines as well as by chargingfees for terminalling services at our facilities. Revenues are also generated by acquiring and marketing crude oil. Generally, crude oil purchases areentered into in contemplation of or simultaneously with corresponding sale transactions involving physical deliveries, which enables us to secure aprofit on the transaction at the time of purchase.Trends and OutlookWe continue to evaluate and execute strategies to enhance unitholder value through growth, as well as the integration and optimization of our diversifiedasset portfolio. We intend to target a minimum distribution coverage ratio of 1.10x, thereby promoting a prudent balance between distribution rate increasesand enhanced financial flexibility and strength while maintaining our investment grade ratings. We anticipate significant earnings growth in 2018 from thecompletion of our project backlog. We also continue to seek asset optimization opportunities through strategic transactions among us and our subsidiariesand/or affiliates, and we expect to continue to evaluate and execute on such opportunities. As we have in the past, we will evaluate growth projects andacquisitions as such opportunities may be identified in the future, and we believe that the current capital markets are conducive to funding such futureprojects.With respect to commodity prices, crude oil and NGL prices have rebounded sharply from the lows experienced in early 2016. Current commodity pricinghas increased activities in several basins, as reflected by current rig counts. The addition of several ethane crackers and export projects currently underconstruction should help to volumetrically balance this market. Other factors such as reduced wet gas extraction will also help to balance this market andpositively impact prices. Bakken crude oil output is continuing to increase, supporting strong spreads between North Dakota and the Gulf Coast.Natural gas pricing is expected to remain within a range similar to recent history as increased supply continues to outpace demand. Texas intrastate naturalgas spreads are strong mostly due to increased production in the Permian Basin; Permian production is expected to continue growing considerably over thenext several years, and most new takeaway capacity projects are not scheduled to go into service until beyond 2018. New demand occurring in several areassuch as exports to Mexico and Canada, LNG exports, nuclear power plant de-commissioning, as well as continued coal to gas switching for power generation,will help pricing; however, supply is continuing to increase.Results of OperationsWe report Segment Adjusted EBITDA as a measure of segment performance. We define Segment Adjusted EBITDA as earnings before interest, taxes,depreciation, depletion, amortization and other non-cash items, such as non-cash compensation expense, gains and losses on disposals of assets, theallowance for equity funds used during construction, unrealized gains and losses on commodity risk management activities, non-cash impairment charges,losses on extinguishments of debt and other non-operating income or expense items. Unrealized gains and losses on commodity risk management activitiesinclude unrealized gains and losses on commodity derivatives and inventory fair value adjustments (excluding lower of cost or market adjustments). SegmentAdjusted EBITDA reflects amounts for unconsolidated affiliates based on the Partnership’s proportionate ownership.Adjusted EBITDA is a non-GAAP measure. Although we include Segment Adjusted EBITDA in this report, we have not included an analysis of theconsolidated measure, Adjusted EBITDA. We have included a total of Segment Adjusted EBITDA for all segments, which is reconciled to the GAAP measureof net income in the consolidated results sections that follow.As discussed in Note 1 to the consolidated financial statements in “Item 8. Financial Statements and Supplementary Data,” the merger of legacy ETP andlegacy Sunoco Logistics in April 2017 resulted in legacy ETP being treated as the surviving entity from an accounting perspective. Accordingly, thefinancial data below reflects the consolidated financial information of legacy ETP.73 Table of ContentsAs discussed in Note 2 to the Partnership’s consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data,” in thefourth quarter of 2017, the Partnership changed its accounting policy related to certain inventories. Certain crude oil, refined product and NGL inventorieswere changed from last-in, first-out (“LIFO”) method to the weighted average cost method. These changes have been applied retrospectively to all periodspresented, and the prior period amounts reflected below have been adjusted from those amounts previously reported.Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016Consolidated Results Years Ended December 31, 2017 2016* ChangeSegment Adjusted EBITDA: Intrastate transportation and storage$626 $613 $13Interstate transportation and storage1,098 1,117 (19)Midstream1,481 1,133 348NGL and refined products transportation and services1,641 1,496 145Crude oil transportation and services1,379 834 545All other487 540 (53)Total6,712 5,733 979Depreciation, depletion and amortization(2,332) (1,986) (346)Interest expense, net(1,365) (1,317) (48)Gains on acquisitions— 83 (83)Impairment losses(920) (813) (107)Losses on interest rate derivatives(37) (12) (25)Non-cash unit-based compensation expense(74) (80) 6Unrealized gain (loss) on commodity risk management activities56 (131) 187Losses on extinguishments of debt(42) — (42)Adjusted EBITDA related to unconsolidated affiliates(984) (946) (38)Equity in earnings of unconsolidated affiliates156 59 97Impairment of investments in unconsolidated affiliates(313) (308) (5)Other, net148 115 33Income before income tax benefit1,005 397 608Income tax benefit1,496 186 1,310Net income$2,501 $583 $1,918* As adjusted.See the detailed discussion of Segment Adjusted EBITDA below.Depreciation, Depletion and Amortization. Depreciation, depletion and amortization expense increased primarily due to additional depreciation from assetsrecently placed in service and recent acquisitions.Impairment Losses. During the year ended December 31, 2017, the Partnership recorded impairments to goodwill associated with the compression business of$223 million, the entity that owns the general partner of Panhandle of $229 million, interstate transportation and storage operations of $262 million, andrefined products transportation and services operations of $79 million. Also, during the year ended December 31, 2017, the Partnership recorded animpairment to the property, plant and equipment of Sea Robin of $127 million. During the year ended December 31, 2016, the Partnership recordedimpairments to goodwill associated with the interstate transportation and storage operations $638 million and the midstream operations $32 million. Also,during the year ended December 31, 2016, the Partnership recorded impairments to the property, plant and equipment in the interstate transportation andstorage segment $133 million and in the midstream segment $10 million. Additional discussion on these impairments is included in “Estimates and CriticalAccounting Policies” below.74 Table of ContentsLosses on Interest Rate Derivatives. Our interest rate derivatives are not designated as hedges for accounting purposes; therefore, changes in fair value arerecorded in earnings each period. Losses on interest rate derivatives during the years ended December 31, 2017 and 2016 resulted from decreases in forwardinterest rates, which caused our forward-starting swaps to change in value.Unrealized Gain (Loss) on Commodity Risk Management Activities.

Additional discussion on these impairments is included in “Estimates and Critical Accounting Policies” below.Other, net. Other, net primarily includes amortization of regulatory assets and other income and expense amounts.Income Tax Benefit. On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. Among other provisions, the highest corporate federal income taxrate was reduced from 35% to 21% for taxable years beginning after December 31, 2017. As a result, the Partnership recognized a deferred tax benefit of $1.56billion in December 2017. For the year ended December 2016, the Partnership recorded an income tax benefit due to pre-tax losses at its corporatesubsidiaries.75 Table of ContentsSupplemental Information on Unconsolidated AffiliatesThe following table presents financial information related to unconsolidated affiliates: Years Ended December 31, 2017 2016 ChangeEquity in earnings (losses) of unconsolidated affiliates: Citrus$144 $102 $42FEP53 51 2MEP38 40 (2)HPC(1)(168) 31 (199)Sunoco LP(2)12 (211) 223Other77 46 31Total equity in earnings of unconsolidated affiliates$156 $59 $97 Adjusted EBITDA related to unconsolidated affiliates(3): Citrus$336 $329 $7FEP74 75 (1)MEP88 90 (2)HPC46 61 (15)Sunoco LP268 271 (3)Other172 120 52Total Adjusted EBITDA related to unconsolidated affiliates$984 $946 $38 Distributions received from unconsolidated affiliates: Citrus$156 $144 $12FEP47 65 (18)MEP114 74 40HPC35 51 (16)Sunoco LP144 138 6Other80 69 11Total distributions received from unconsolidated affiliates$576 $541 $35(1) For the year ended December 31, 2017, equity in earnings (losses) of unconsolidated affiliates includes the impact of non-cash impairments recorded byHPC, which reduced the Partnership’s equity in earnings by $185 million.(2) For the years ended December 31, 2017 and 2016, equity in earnings (losses) of unconsolidated affiliates includes the impact of non-cash impairmentsrecorded by Sunoco LP, which reduced the Partnership’s equity in earnings by $176 million and $277 million, respectively.(3) These amounts represent our proportionate share of the Adjusted EBITDA of our unconsolidated affiliates and are based on our equity in earnings orlosses of our unconsolidated affiliates adjusted for our proportionate share of the unconsolidated affiliates’ interest, depreciation, depletion,amortization, non-cash items and taxes.Segment Operating ResultsWe evaluate segment performance based on Segment Adjusted EBITDA, which we believe is an important performance measure of the core profitability ofour operations. This measure represents the basis of our internal financial reporting and is one of the performance measures used by senior management indeciding how to allocate capital resources among business segments.The tables below identify the components of Segment Adjusted EBITDA, which is calculated as follows:•Segment margin, operating expenses, and selling, general and administrative expenses. These amounts represent the amounts included in ourconsolidated financial statements that are attributable to each segment.76 Table of Contents•Unrealized gains or losses on commodity risk management activities and inventory valuation adjustments. These are the unrealized amounts that areincluded in cost of products sold to calculate segment margin. These amounts are not included in Segment Adjusted EBITDA; therefore, the unrealizedlosses are added back and the unrealized gains are subtracted to calculate the segment measure.•Non-cash compensation expense. These amounts represent the total non-cash compensation recorded in operating expenses and selling, general andadministrative expenses. This expense is not included in Segment Adjusted EBITDA and therefore is added back to calculate the segment measure.•Adjusted EBITDA related to unconsolidated affiliates. These amounts represent our proportionate share of the Adjusted EBITDA of our unconsolidatedaffiliates. Amounts reflected are calculated consistently with our definition of Adjusted EBITDA.In the following analysis of segment operating results, a measure of segment margin is reported for segments with sales revenues. Segment Margin is a non-GAAP financial measure and is presented herein to assist in the analysis of segment operating results and particularly to facilitate an understanding of theimpacts that changes in sales revenues have on the segment performance measure of Segment Adjusted EBITDA. Segment Margin is similar to the GAAPmeasure of gross margin, except that Segment Margin excludes charges for depreciation, depletion and amortization.In addition, for certain segments, the sections below include information on the components of Segment Margin by sales type, which components areincluded in order to provide additional disaggregated information to facilitate the analysis of Segment Margin and Segment Adjusted EBITDA. For example,these components include transportation margin, storage margin, and other margin. These components of Segment Margin are calculated consistent with thecalculation of Segment Margin; therefore, these components also exclude charges for depreciation, depletion and amortization.For additional information regarding our business segments, see “Item 1. Business” and Notes 1 and 15 to our consolidated financial statements in “Item 8.Financial Statements and Supplementary Data.”Following is a reconciliation of Segment Margin to operating income, as reported in the Partnership’s consolidated statements of operations: Years Ended December 31, 2017 2016Intrastate transportation and storage$756 $716Interstate transportation and storage934 969Midstream2,182 1,798NGL and refined products transportation and services2,140 1,856Crude oil transportation and services1,877 1,123All other392 330Intersegment eliminations(28) (45)Total segment margin8,253 6,747Less: Operating expenses2,170 1,839Depreciation, depletion and amortization2,332 1,986Selling, general and administrative434 348Impairment losses920 813Operating income$2,397 $1,76177 Table of ContentsIntrastate Transportation and Storage Years Ended December 31, 2017 2016 ChangeNatural gas transported (BBtu/d)8,760 8,328 432Revenues$3,083 $2,613 $470Cost of products sold2,327 1,897 430Segment margin756 716 40Unrealized (gains) losses on commodity risk management activities(5) 19 (24)Operating expenses, excluding non-cash compensation expense(168) (162) (6)Selling, general and administrative expenses, excluding non-cash compensation expense(22) (22) —Adjusted EBITDA related to unconsolidated affiliates64 61 3Other1 1 —Segment Adjusted EBITDA$626 $613 $13Volumes. For the year ended December 31, 2017 compared to the prior year, transported volumes increased primarily due to higher demand for exports toMexico, more favorable market pricing, and the addition of new pipelines to our intrastate pipeline system. These increases were partially offset by lowerproduction volumes in the Barnett Shale region.Segment Margin.

For the year ended December 31, 2017 compared to the prior year, Segment Adjusted EBITDA related to our intrastatetransportation and storage segment increased due to the net impacts of the following:•an increase of $74 million in natural gas sales and other (excluding net changes in unrealized gains and losses of $6 million) primarily due to higherrealized gains from pipeline optimization activity;•an increase of $10 million in retained fuel sales (excluding net changes in unrealized gains and losses of $4 million) primarily due to higher marketprices. The average spot price at the Houston Ship Channel location increased 22% for the year ended December 31, 2017 compared to the prior year;and•an increase of $3 million in adjusted EBITDA related to unconsolidated affiliates primarily due to an increase of $16 million related to two new jointventure pipelines placed in service in 2017, offset by a decrease of $6 million due to lower demand volumes related to renegotiation of a contract on ourLouisiana intrastate pipeline system in 2017 and a decrease of $7 million due to a reserve recorded in 2017 pursuant to the bankruptcy filing of atransport customer on our Louisiana intrastate system; offset by•a decrease in transportation fees of $57 million due to renegotiated contracts resulting in lower billed volumes. This decrease was offset by increasedmargin from optimization activity recorded in natural gas sales and other;•a decrease of $11 million in storage margin (excluding net changes in unrealized gains and losses of $14 million related to fair value inventoryadjustments and unrealized gains and losses on derivatives), as discussed below; and•an increase of $6 million in operating expenses primarily due to higher compression fuel expense relating to increased market price and run times atvarious compressor stations.78 Table of ContentsStorage margin was comprised of the following: Years Ended December 31, 2017 2016 ChangeWithdrawals from storage natural gas inventory (BBtu)27,195 38,905 (11,710)Realized margin on natural gas inventory transactions$24 $36 $(12)Fair value inventory adjustments(35) 76 (111)Unrealized gains (losses) on derivatives38 (87) 125Margin recognized on natural gas inventory, including related derivatives27 25 2Revenues from fee-based storage26 25 1Total storage margin$53 $50 $3The changes in storage margin were primarily due to the movement in market price of the physical storage gas and the financial derivatives used to hedgethat gas.Interstate Transportation and Storage Years Ended December 31, 2017 2016 ChangeNatural gas transported (BBtu/d)6,082 5,476 606Natural gas sold (BBtu/d)18 19 (1)Revenues$934 $969 $(35)Operating expenses, excluding non-cash compensation, amortization and accretionexpenses(296) (302) 6Selling, general and administrative expenses, excluding non-cash compensation,amortization and accretion expenses(46) (47) 1Adjusted EBITDA related to unconsolidated affiliates498 494 4Other8 3 5Segment Adjusted EBITDA$1,098 $1,117 $(19)Volumes.

For the year ended December 31, 2017 compared to the prior year, Segment Adjusted EBITDA related to our interstatetransportation and storage segment decreased due to the net impacts of the following:•a net decrease of $35 million in revenues primarily due to a decrease in reservation revenues of $45 million on the Panhandle, Trunkline, andTranswestern pipelines, a decrease of $17 million in gas parking service related revenues on the Panhandle and Trunkline pipelines primarily due to lackof customer demand resulting from weak spreads, a decrease of $19 million in revenues on the Tiger pipeline due to contract restructuring, and a decreaseof $5 million on the Sea Robin pipeline due to producer maintenance and production declines. These decreases were partially offset by $55 million ofincremental revenues from the placement in partial service of the Rover pipeline effective August 31, 2017; offset by•a decrease in operating expenses of $6 million primarily due to lower allocated costs of $8 million and lower lease storage expense of $4 million due toexpiration of a lease. These decreases were partially offset by higher ad valorem taxes resulting from higher valuations;•an increase in adjusted EBITDA from unconsolidated affiliates of $4 million due to an increase of $6 million related to a legal settlement, an increase of$3 million resulting from higher sales of short term firm capacity on Citrus and $2 million related to higher tax gross up income from reimbursableprojects on Citrus. These increases were partially offset by lower reservation revenues on MEP primarily due to a contract modification and expiringcontracts; and•an increase in other of $5 million primarily due to higher tax gross up income from reimbursable projects.79 Table of ContentsMidstream Years Ended December 31, 2017 2016 ChangeGathered volumes (BBtu/d)10,956 9,814 1,142NGLs produced (MBbls/d)457 438 19Equity NGLs (MBbls/d)27 31 (4)Revenues$6,943 $5,179 $1,764Cost of products sold4,761 3,381 1,380Segment margin2,182 1,798 384Unrealized (gains) losses on commodity risk management activities(15) 15 (30)Operating expenses, excluding non-cash compensation expense(638) (621) (17)Selling, general and administrative expenses, excluding non-cash compensation expense(78) (84) 6Adjusted EBITDA related to unconsolidated affiliates28 24 4Other2 1 1Segment Adjusted EBITDA$1,481 $1,133 $348Volumes.

For the year ended December 31, 2016 compared to the prior year, Segment Adjusted EBITDA related to our intrastatetransportation and storage segment increased due to the net impacts of the following:•an increase of $3 million in transportation fees, despite lower throughput volumes, due to fees from renegotiated and newly initiated fixed fee contractsprimarily on our Houston Pipeline system;•an increase of $34 million in natural gas sales (excluding changes in unrealized losses of $17 million) primarily due to higher realized gains from thebuying and selling of gas along our system;•a decrease of $9 million from the sale of retained fuel, primarily due to lower market prices and lower volumes. The average spot price at the HoustonShip Channel location decreased 5% for the year ended December 31, 2016 compared to the prior year;•an increase of $37 million in storage margin (excluding net changes in unrealized amounts of $28 million related to fair value inventory adjustments andunrealized gains and losses on derivatives), as discussed below; and•a decrease of $3 million in general and administrative expenses primarily due to lower legal fees and insurance costs, as well as allocations betweensegments.Storage margin was comprised of the following: Years Ended December 31, 2016 2015 ChangeWithdrawals from storage natural gas inventory (BBtu)38,905 15,783 23,122Realized margin on natural gas inventory transactions$36 $(2) $38Fair value inventory adjustments76 4 72Unrealized gains (losses) on derivatives(87) 12 (99)Margin recognized on natural gas inventory, including related derivatives25 14 11Revenues from fee-based storage25 27 (2)Total storage margin$50 $41 $9The changes in storage margin were primarily driven by the timing of withdrawals and sales of natural gas from our Bammel storage cavern, as well as thetiming of settlement of related derivative hedging contracts.88 Table of ContentsInterstate Transportation and Storage Years Ended December 31, 2016 2015 ChangeNatural gas transported (BBtu/d)5,476 6,074 (598)Natural gas sold (BBtu/d)19 17 2Revenues$969 $1,025 $(56)Operating expenses, excluding non-cash compensation, amortization and accretionexpenses(302) (304) 2Selling, general and administrative, excluding non-cash compensation, amortization andaccretion expenses(47) (52) 5Adjusted EBITDA related to unconsolidated affiliates494 486 8Other3 — 3Segment Adjusted EBITDA$1,117 $1,155 $(38)Volumes. For the year ended December 31, 2016 compared to the prior year, transported volumes decreased 424 BBtu/d on the Trunkline pipeline due to thetransfer of one of the pipelines at Trunkline which was repurposed from natural gas service to crude oil service and lower utilization resulting from lowercustomer demand. Transported volumes decreased 82 BBtu/d on the Transwestern pipe line due to milder weather in the West and decreased 76 BBtu/d onthe Sea Robin pipeline due to reduced supply as a result of producer system maintenance and overall lower production.Segment Adjusted EBITDA. For the year ended December 31, 2016 compared to the prior year, Segment Adjusted EBITDA related to our interstatetransportation and storage segment decreased due to the net impacts of the following:•a decrease of $26 million in revenues due to contract restructuring on the Tiger pipeline, a decrease of $17 million due to lower reservation revenues onthe Panhandle and Trunkline pipelines from capacity sold at lower rates and lower sales of capacity in the Phoenix and San Juan areas on theTranswestern pipeline, a decrease of $14 million due to the transfer of one of the Trunkline pipelines which was repurposed from natural gas service tocrude oil service, a decrease of $11 million due to the expiration of a transportation rate schedule on the Transwestern pipeline, and a decrease of $10million on the Sea Robin pipeline due to declines in production and third-party maintenance. These decreases were partially offset by higher reservationrevenues on the Transwestern pipeline of $18 million, primarily from a growth project, and higher parking revenues of $9 million, primarily on thePanhandle and Trunkline pipelines; partially offset by•an increase of $8 million in Adjusted EBITDA related to unconsolidated affiliates primarily due to higher margins from sales of additional capacity onCitrus of $6 million and lower operating expenses of $5 million, offset by lower margins on MEP of $4 million due to a customer bankruptcy;•a decrease of $2 million in operating expenses primarily due to lower maintenance project costs of $5 million and lower allocated costs of $3 million.These decreases were partially offset by an increase of $7 million in ad valorem tax expense due to higher current year assessments of $2 million and aprior period credit and settlement of ad valorem taxes in 2015 of $5 million;•a decrease of $5 million in selling, general and administrative expenses primarily due to $5 million in lower allocated costs; and•an increase of $3 million in other primarily due to the tax gross-up associated with reimbursable projects on the Transwestern and Panhandle pipelines.89 Table of ContentsMidstream Years Ended December 31, 2016 2015 ChangeGathered volumes (BBtu/d):9,814 9,981 (167)NGLs produced (MBbls/d):438 406 32Equity NGLs (MBbls/d):31 28 3Revenues$5,179 $5,056 $123Cost of products sold3,381 3,264 117Segment margin1,798 1,792 6Unrealized losses on commodity risk management activities15 82 (67)Operating expenses, excluding non-cash compensation expense(621) (616) (5)Selling, general and administrative, excluding non-cash compensation expense(84) (44) (40)Adjusted EBITDA related to unconsolidated affiliates24 20 4Other1 3 (2)Segment Adjusted EBITDA$1,133 $1,237 $(104)Volumes.

For the year ended December 31, 2016 compared to the prior year, Segment Adjusted EBITDA related to our NGL and refinedproducts transportation and services segment increased due to the net impacts of the following:•an increase of $36 million in storage margin primarily due to increased volumes from our Mont Belvieu fractionators. Throughput volumes, on which weearn a fee in our storage assets, increased 34% resulting in an increase of $18 million compared to the prior year. We also realized an increase of $8million due to increased demand for our leased storage capacity as a result of more favorable market conditions. Finally, we realized increased terminalfees and pipeline lease fees of $8 million, as well as increased blending gains of $2 million resulting from higher volumes during the 2016 period;•an increase of $239 million in NGL and refined product transportation and terminal margin due to the ramp-up of several organic growth projects,including Mariner East 1, Mariner South and Allegheny Access as well as increased volumes from all producing regions, with the Permian region beingthe most significant among them;91 Table of Contents•a $4 million increase in contributions from joint venture interests primarily driven by the acquisition of an additional 1.7% ownership interest inExplorer Pipeline Company; and•an increase of $118 million in NGL processing and fractionation margin (excluding net changes in unrealized gains and losses of $11 million) primarilydue to higher NGL volumes from all producing regions, as detailed in our transport fees explanation above. We placed approximately 118 MBbls/d offractionation capacity in-service in 2016, allowing our Mont Belvieu fractionators to handle the significant increase in volumes from year to year.Additional barrels fractionated and an associated increase in blending gains at our fractionators resulted in a margin increase of $101 million. Wedelivered approximately 26% more barrels to our Mariner South LPG export terminal in the 2016 period, which resulted in an increase of $22 million incargo loading fees and blending fees compared to the prior year. These gains were offset by an increase in storage fees paid of $2 million, and a decreasein margin from our refinery services operations of $3 million; partially offset by•a decrease in marketing margin of $42 million (excluding net changes in unrealized gains and losses of $50 million) due to lower spreads compared toprior year as well as the timing of the withdrawal of NGL component product inventory and the recognition of margin from other optimization activities;and•an increase of $33 million in operating expenses primarily due to increased costs associated with organic growth projects such as our third fractionator atMont Belvieu, Mariner East 1, Mariner South and Allegheny Access.Crude Oil Transportation and Services Years Ended December 31, 2016 2015 ChangeCrude Transportation Volumes (MBbls/d)2,652 2,276 376Crude Terminals Volumes (MBbls/d)1,537 1,400 137Revenue$7,539 $8,980 $(1,441)Cost of products sold6,416 8,158 (1,742)Segment margin1,123 822 301Unrealized losses on commodity risk management activities2 — 2Operating expenses, excluding non-cash compensation expense(247) (246) (1)Selling, general and administrative expenses, excluding non-cash compensation expense(58) (53) (5)Adjusted EBITDA related to unconsolidated affiliates14 (2) 16Segment Adjusted EBITDA$834 $521 $313Segment Adjusted EBITDA.

Accordingly, we do not have any significant financial commitments for maintenance capitalexpenditures in our businesses. From time to time we experience increases in pipe costs due to a number of reasons, including but not limited to, delays fromsteel mills, limited selection of mills capable of producing large diameter pipe timely, higher steel prices and other factors beyond our control. However, weinclude these factors in our anticipated growth capital expenditures for each year.We generally fund maintenance capital expenditures and distributions with cash flows from operating activities. We generally fund growth capitalexpenditures with proceeds of borrowings under credit facilities, long-term debt, the issuance of additional Common Units or a combination thereof.As of December 31, 2017, in addition to $306 million of cash on hand, we had available capacity under the ETP Credit Facilities of $2.51 billion. Based onour current estimates, we expect to utilize capacity under the ETP Credit Facilities, along with cash from operations, to fund our announced growth capitalexpenditures and working capital needs through the end of 2018; however, we may issue debt or equity securities prior to that time as we deem prudent toprovide liquidity for new capital projects, to maintain investment grade credit metrics or other partnership purposes.Cash FlowsOur internally generated cash flows may change in the future due to a number of factors, some of which we cannot control. These include regulatory changes,the price for our products and services, the demand for such products and services, margin requirements resulting from significant changes in commodityprices, operational risks, the successful integration of our acquisitions, and other factors.Operating ActivitiesChanges in cash flows from operating activities between periods primarily result from changes in earnings (as discussed in “Results of Operations” above),excluding the impacts of non-cash items and changes in operating assets and liabilities. Non-cash items include recurring non-cash expenses, such asdepreciation, depletion and amortization expense and non-cash compensation expense. The increase in depreciation, depletion and amortization expenseduring the periods presented primarily resulted from construction and acquisitions of assets, while changes in non-cash unit-based compensation expenseresulted from changes in the number of units granted and changes in the grant date fair value estimated for such grants. Cash flows from operating activitiesalso differ from earnings as a result of non-cash charges that may not be recurring such as impairment charges and allowance for equity funds used duringconstruction. The allowance for equity funds used during construction increases in periods when we have a significant amount of interstate pipelineconstruction in progress. Changes in operating assets and liabilities between periods result from factors such as the changes in the value of derivative assetsand liabilities, timing of accounts receivable collection, payments on accounts payable, the timing of purchase and sales of inventories, and the timing ofadvances and deposits received from customers.94 Table of ContentsFollowing is a summary of operating activities by period:Year Ended December 31, 2017Cash provided by operating activities in 2017 was $4.49 billion and net income was $2.50 billion.

Distributions to partners increased between the periods as a result of increases in thenumber of Common Units outstanding.Following is a summary of financing activities by period:Year Ended December 31, 2017Cash provided by financing activities was $934 million in 2017. We received $2.28 billion in net proceeds from Common Unit offerings and $1.48 billionin net proceeds from the issuance of Preferred Units. Net proceeds from the offerings were used to repay outstanding borrowings under the ETP CreditFacilities, to fund capital expenditures and acquisitions, as well as for general partnership purposes. In 2017, we paid distributions of $3.47 billion to ourpartners and we paid distributions of $430 million to noncontrolling interests. In addition, we received capital contributions from noncontrolling interests of$1.21 billion.

Net proceeds from the offerings were used to repay outstandingborrowings under the ETLP Credit Facility, to fund capital expenditures and acquisitions,96 Table of Contentsas well as for general partnership purposes. In 2016, we had a net increase in our debt level of $4.24 billion primarily due to borrowings under our creditfacilities in aggregate of $4.04 billion, legacy Sunoco Logistics’ issuance of $550 million in aggregate principal amount of senior notes in July 2016 and$168 million of debt assumed by the Partnership in connection with the PennTex Acquisition, partially offset by repayments of long-term debt. In addition,we incurred debt issuance costs of $22 million. In 2016, we paid distributions of $3.54 billion to our partners and we paid distributions of $481 million tononcontrolling interests. In addition, we received capital contributions from noncontrolling interests of $236 million.Year Ended December 31, 2015Cash provided by financing activities was $4.94 billion in 2015. We received $1.43 billion in net proceeds from Common Unit offerings, and oursubsidiaries received $1.52 billion in net proceeds from the issuance of common units. Net proceeds from the offerings were used to repay outstandingborrowings under the ETLP Credit Facility, to fund capital expenditures and acquisitions, as well as for general partnership purposes. In 2015, we had a netincrease in our debt level of $4.85 billion primarily due to ETP’s issuance of $2.50 billion and $3.00 billion in aggregate principal amount of senior notes inMarch 2015 and June 2015, respectively, and legacy Sunoco Logistics’ issuance of $1.00 billion in aggregate principal amount of senior notes in November2015. In addition, we incurred debt issuance costs of $63 million. In 2015, we paid distributions of $3.13 billion to our partners and we paid distributions of$338 million to noncontrolling interests. In addition, we received capital contributions from noncontrolling interest of $841 million.Description of IndebtednessOur outstanding consolidated indebtedness was as follows: December 31, 2017 2016ETP Senior Notes$27,005 $24,855Transwestern Senior Notes575 657Panhandle Senior Notes785 1,085Sunoco, Inc.

The ETP Five-Year Facility contains an accordion feature, under which thetotal aggregate commitments may be increased up to $6.0 billion under certain conditions. We use the ETP Credit Facilities to provide temporary financingfor our growth projects, as well as for general partnership purposes.Borrowings under the ETP Credit Facilities are unsecured and initially guaranteed by Sunoco Logistics Partners Operations L.P. Borrowings under the ETPCredit Facilities will bear interest at a eurodollar rate or a base rate, at our option, plus an applicable margin. In addition, we will be required to pay aquarterly commitment fee to each lender equal to the product of the applicable rate and such lender’s applicable percentage of the unused portion of theaggregate commitments under the ETP Credit Facilities. Concurrent with the closing of the ETP Credit Facilities, we repaid the entire amount outstandingand terminated our previously existing $3.75 billion ETLP Credit Facility and $2.50 billion Sunoco Logistics Credit Facility.We typically repay amounts outstanding under the ETP Credit Facilities with proceeds from common unit offerings or long-term notes offerings. The timingof borrowings depends on the Partnership’s activities and the cash available to fund those activities. The repayments of amounts outstanding under the ETPCredit Facilities depend on multiple factors, including market conditions and expectations of future working capital needs, and ultimately are a financingdecision made by management. Therefore, the balance outstanding under the ETP Credit Facilities may vary significantly between periods. We do notbelieve that such fluctuations indicate a significant change in our liquidity position, because we expect to continue to be able to repay amounts outstandingunder the ETP Credit Facilities with proceeds from common unit offerings or long-term note offerings.As of December 31, 2017, the ETP Five-Year Facility had $2.29 billion outstanding, of which $2.01 billion was commercial paper. The amount available forfuture borrowings was $1.56 billion after taking into account letters of credit of $150 million. The weighted average interest rate on the total amountoutstanding as of December 31, 2017 was 2.48%.As of December 31, 2017, the ETP 364-Day Facility had $50 million outstanding, and the amount available for future borrowings was $950 million. Theweighted average interest rate on the total amount outstanding as of December 31, 2017 was 5.00%.Bakken Credit FacilityIn August 2016, Energy Transfer Partners, L.P., Sunoco Logistics and Phillips 66 completed project-level financing of the Bakken Pipeline. The $2.50 billioncredit facility is anticipated to provide substantially all of the remaining capital necessary to complete the projects and matures in August 2019 (the “BakkenCredit Facility”). As of December 31, 2017, the Bakken Credit Facility had $2.50 billion of outstanding borrowings. The weighted average interest rate onthe total amount outstanding as of December 31, 2017 was 3.00%.Covenants Related to Our Credit AgreementsCovenants Related to ETPThe agreements relating to the ETP senior notes contain restrictive covenants customary for an issuer with an investment-grade rating from the ratingagencies, which covenants include limitations on liens and a restriction on sale-leaseback transactions.The ETP Credit Facilities contains covenants that limit (subject to certain exceptions) the Partnership’s and certain of the Partnership’s subsidiaries’ abilityto, among other things: •incur indebtedness;•grant liens;•enter into mergers;•dispose of assets;•make certain investments;•make Distributions (as defined in the ETP Credit Facilities) during certain Defaults (as defined in the ETP Credit Facilities) and during any Event ofDefault (as defined in the ETP Credit Facilities);•engage in business substantially different in nature than the business currently conducted by the Partnership and its subsidiaries;•engage in transactions with affiliates; and•enter into restrictive agreements.The ETP Credit Facilities applicable margin and rate used in connection with the interest rates and commitment fees, respectively, are based on the creditratings assigned to our senior, unsecured, non-credit enhanced long-term debt. The applicable margin for eurodollar rate loans under the ETP Five-YearFacility ranges from 1.125% to 2.000% and the applicable margin for base rate98 Table of Contentsloans ranges from 0.125% to 1.000%. The applicable rate for commitment fees under the ETP Five-Year Facility ranges from 0.125% to 0.300%. Theapplicable margin for eurodollar rate loans under the ETP 364-Day Facility ranges from 1.125% to 1.750% and the applicable margin for base rate loansranges from 0.250% to 0.750%. The applicable rate for commitment fees under the ETP 364-Day Facility ranges from 0.125% to 0.225%.The ETP Credit Facilities contain various covenants including limitations on the creation of indebtedness and liens, and related to the operation and conductof our business. The ETP Credit Facilities also limit us, on a rolling four quarter basis, to a maximum Consolidated Funded Indebtedness to ConsolidatedEBITDA ratio, as defined in the underlying credit agreements, of 5.0 to 1, which can generally be increased to 5.5 to 1 during a Specified Acquisition Period.Our Leverage Ratio was 3.96 to 1 at December 31, 2017, as calculated in accordance with the credit agreements.The agreements relating to the Transwestern senior notes contain certain restrictions that, among other things, limit the incurrence of additional debt, the saleof assets and the payment of dividends and specify a maximum debt to capitalization ratio.Failure to comply with the various restrictive and affirmative covenants of our revolving credit facilities could require us to pay debt balances prior toscheduled maturity and could negatively impact the Operating Companies’ ability to incur additional debt and/or our ability to pay distributions.Covenants Related to PanhandlePanhandle is not party to any lending agreement that would accelerate the maturity date of any obligation due to a failure to maintain any specific creditrating, nor would a reduction in any credit rating, by itself, cause an event of default under any of Panhandle’s lending agreements. Financial covenants existin certain of Panhandle’s debt agreements that require Panhandle to maintain a certain level of net worth, to meet certain debt to total capitalization ratiosand to meet certain ratios of earnings before depreciation, interest and taxes to cash interest expense. A failure by Panhandle to satisfy any such covenantwould give rise to an event of default under the associated debt, which could become immediately due and payable if Panhandle did not cure such defaultwithin any permitted cure period or if Panhandle did not obtain amendments, consents or waivers from its lenders with respect to such covenants.Panhandle’s restrictive covenants include restrictions on debt levels, restrictions on liens securing debt and guarantees, restrictions on mergers and on thesales of assets, capitalization requirements, dividend restrictions, cross default and cross-acceleration and prepayment of debt provisions. A breach of any ofthese covenants could result in acceleration of Panhandle’s debt and other financial obligations and that of its subsidiaries.In addition, Panhandle and/or its subsidiaries are subject to certain additional restrictions and covenants. These restrictions and covenants include limitationson additional debt at some of its subsidiaries; limitations on the use of proceeds from borrowing at some of its subsidiaries; limitations, in some cases, ontransactions with its affiliates; limitations on the incurrence of liens; potential limitations on the abilities of some of its subsidiaries to declare and paydividends and potential limitations on some of its subsidiaries to participate in Panhandle’s cash management program; and limitations on Panhandle’sability to prepay debt.Covenants Related to Bakken Credit FacilityThe Bakken Credit Facility contains standard and customary covenants for a financing of this type, subject to materiality, knowledge and otherqualifications, thresholds, reasonableness and other exceptions. These standard and customary covenants include, but are not limited to:•prohibition of certain incremental secured indebtedness;•prohibition of certain liens / negative pledge;•limitations on uses of loan proceeds;•limitations on asset sales and purchases;•limitations on permitted business activities;•limitations on mergers and acquisitions;•limitations on investments;•limitations on transactions with affiliates; and•maintenance of commercially reasonable insurance coverage.99 Table of ContentsA restricted payment covenant is also included in the Bakken Credit Facility which requires a minimum historic debt service coverage ratio (“DSCR”) of notless than 1.20 to 1 (the “Minimum Historic DSCR”) with respect each 12-month period following the commercial in-service date of the Dakota Access andETCO Project in order to make certain restricted payments thereunder.Compliance with our CovenantsWe were in compliance with all requirements, tests, limitations, and covenants related to our debt agreements as of December 31, 2017.Off-Balance Sheet ArrangementsContingent Residual Support Agreement – AmeriGasIn connection with the closing of the contribution of its propane operations in January 2012, ETP previously provided contingent residual support of certaindebt obligations of AmeriGas. AmeriGas has subsequently repaid the remainder of the related obligations and ETP no longer provides contingent residualsupport for any AmeriGas notes.Guarantee of Sunoco LP NotesIn connection with previous transactions whereby Retail Holdings contributed assets to Sunoco LP, Retail Holdings provided a limited contingent guaranteeof collection, but not of payment, to Sunoco LP with respect to (i) $800 million principal amount of 6.375% senior notes due 2023 issued by Sunoco LP, (ii)$800 million principal amount of 6.25% senior notes due 2021 issued by Sunoco LP and (iii) $2.035 billion aggregate principal for Sunoco LP’s term loandue 2019. In December 2016, Retail Holdings contributed its interests in Sunoco LP, along with the assignment of the guarantee of Sunoco LP’s senior notes,to its subsidiary, ETC M-A Acquisition LLC (“ETC M-A”).On January 23, 2018, Sunoco LP redeemed the previously guaranteed senior notes and issued the following notes for which ETC M-A has also guaranteedcollection with respect to the payment of principal amounts:•$1.00 billion aggregate principal amount of 4.875%, senior notes due 2023;•$800 million aggregate principal amount of 5.50% senior notes due 2026; and•$400 million aggregate principal amount of 5.875% senior notes due 2028.Under the guarantee of collection, ETC M-A would have the obligation to pay the principal of each series of notes once all remedies, including in the contextof bankruptcy proceedings, have first been fully exhausted against Sunoco LP with respect to such payment obligation, and holders of the notes are stillowed amounts in respect of the principal of such notes. ETC M-A will not otherwise be subject to the covenants of the indenture governing the notes.Contractual ObligationsThe following table summarizes our long-term debt and other contractual obligations as of December 31, 2017: Payments Due by PeriodContractual Obligations Total Less Than 1 Year 1-3 Years 3-5 Years More Than 5 YearsLong-term debt $33,212 $1,700 $5,375 $6,746 $19,391Interest on long-term debt(1) 22,204 1,626 2,873 2,447 15,258Payments on derivatives 223 84 139 — —Purchase commitments(2) 3,605 3,443 99 35 28Transportation, natural gas storage andfractionation contracts 25 19 6 — —Operating lease obligations 257 39 73 53 92Other(3) 185 32 56 45 52Total(4) $59,711 $6,943 $8,621 $9,326 $34,821(1)Interest payments on long-term debt are based on the principal amount of debt obligations as of December 31, 2017. With respect to variable rate debt,the interest payments were estimated using the interest rate as of December 31, 2017. To the extent interest rates change, our contractual obligations forinterest payments will change. See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” for further discussion.100 Table of Contents(2)We define a purchase commitment as an agreement to purchase goods or services that is enforceable and legally binding (unconditional) on us thatspecifies all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and theapproximate timing of the transactions. We have long and short-term product purchase obligations for refined product and energy commodities withthird-party suppliers. These purchase obligations are entered into at either variable or fixed prices. The purchase prices that we are obligated to pay undervariable price contracts approximate market prices at the time we take delivery of the volumes. Our estimated future variable price contract paymentobligations are based on the December 31, 2017 market price of the applicable commodity applied to future volume commitments. Actual futurepayment obligations may vary depending on market prices at the time of delivery. The purchase prices that we are obligated to pay under fixed pricecontracts are established at the inception of the contract. Our estimated future fixed price contract payment obligations are based on the contracted fixedprice under each commodity contract. Obligations shown in the table represent estimated payment obligations under these contracts for the periodsindicated.(3) Expected contributions to fund our pension and postretirement benefit plans were included in “Other” above. Environmental liabilities, asset retirementobligations, unrecognized tax benefits, contingency accruals and deferred revenue, which were included in “Other non-current liabilities” in ourconsolidated balance sheets, were excluded from the table above as the amounts do not represent contractual obligations or, in some cases, the amountand/or timing of the cash payments is uncertain.(4) Excludes non-current deferred tax liabilities of $2.88 billion due to uncertainty of the timing of future cash flows for such liabilities.Cash DistributionsCash Distributions Paid by ETPUnder the Partnership’s limited partnership agreement, within 45 days after the end of each quarter, the Partnership distributes all cash on hand at the end ofthe quarter, less reserves established by the general partner in its discretion. This is defined as “available cash” in the partnership agreement. The generalpartner has broad discretion to establish cash reserves that it determines are necessary or appropriate to properly conduct the Partnership’s business. ThePartnership will make quarterly distributions to the extent there is sufficient cash from operations after establishment of cash reserves and payment of fees andexpenses, including payments to the general partner.If cash distributions exceed $0.0833 per unit in a quarter, the holders of the incentive distribution rights receive increasing percentages, up to 48 percent, ofthe cash distributed in excess of that amount. These distributions are referred to as “incentive distributions.”The following table shows the target distribution levels and distribution “splits” between the general and limited partners and the holders of the Partnership’sincentive distribution rights (”IDRs”): Marginal Percentage Interest inDistributions Total Quarterly Distribution Target Amount IDRs Partners (1)Minimum Quarterly Distribution $0.0750 —% 100%First Target Distribution up to $0.0833 —% 100%Second Target Distribution above $0.0833 up to $0.0958 13% 87%Third Target Distribution above $0.0958 up to $0.2638 35% 65%Thereafter above $0.2638 48% 52%(1) Includes general partner and limited partner interests, based on the proportionate ownership of each.101 Table of ContentsDistributions on common units declared and paid by ETP and Sunoco Logistics during the pre-merger periods were as follows:Quarter Ended ETP Sunoco LogisticsDecember 31, 2014 $0.6633 $0.4000March 31, 2015 0.6767 0.4190June 30, 2015 0.6900 0.4380September 30, 2015 0.7033 0.4580December 31, 2015 0.7033 0.4790March 31, 2016 0.7033 0.4890June 30, 2016 0.7033 0.5000September 30, 2016 0.7033 0.5100December 31, 2016 0.7033 0.5200Distributions on common units declared and paid by Post-Merger ETP were as follows:Quarter Ended Record Date Payment Date RateMarch 31, 2017 May 10, 2017 May 16, 2017 $0.5350June 30, 2017 August 7, 2017 August 15, 2017 0.5500September 30, 2017 November 7, 2017 November 14, 2017 0.5650December 31, 2017 February 8, 2018 February 14, 2018 0.5650Distributions declared and paid by ETP to the preferred unitholders were as follows: Distribution per Preferred UnitQuarter Ended Record Date Payment Date Series A Series BDecember 31, 2017 February 1, 2018 February 15, 2018 $15.451 $16.378The total amounts of distributions declared and paid during the periods presented (all from Available Cash from our operating surplus and are shown in theyear with respect to which they relate): Years Ended December 31, ETP Energy Transfer Partners, L.P.

The Partnership adopted ASU 2014-09 on January 1, 2018. The Partnership applied the cumulative catchuptransition method and recognized the cumulative effect of the retrospective application of the standard. The effect of the retrospective application of thestandard was not material.For future periods, we expect that the adoption of this standard will result in a change to revenues with offsetting changes to costs associated primarily withthe designation of certain of our midstream segment agreements to be in-substance supply agreements, requiring amounts that had previously been reportedas revenue under these agreements to be reclassified to a reduction of cost of sales. Changes to revenues along with offsetting changes to costs will also occurdue to changes in the accounting for noncash consideration in multiple of our reportable segments, as well as fuel usage and loss allowances. None of thesechanges is expected to have a material impact on net income.ASU 2016-02In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which establishes the principles thatlessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arisingfrom a lease. The Partnership expects to adopt ASU 2016-02 in the first quarter of 2019 and is currently evaluating the impact that adopting this new standardwill have on the consolidated financial statements and related disclosures.ASU 2016-16On January 1, 2018, the Partnership adopted Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-entity Transfers of Assets OtherThan Inventory (“ASU 2016-16”), which requires that entities recognize the income tax consequences of an intra-entity transfer of an asset other thaninventory when the transfer occurs. The amendments in this update do not change GAAP for the pre-tax effects of an intra-entity asset transfer under Topic810, Consolidation, or for an intra-entity transfer of inventory. We do not anticipate a material impact to our financial position or results of operations as aresult of the adoption of this standard.ASU 2017-04In January 2017, the FASB issued ASU No. 2017-04 “Intangibles-Goodwill and other (Topic 350): Simplifying the test for goodwill impairment.” Theamendments in this update remove the second step of the two-step test currently required by Topic 350. An entity will apply a one-step quantitative test andrecord the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwillallocated to the reporting unit. The new guidance did not amend the optional qualitative assessment of goodwill impairment. The standard requiresprospective application and therefore will only impact periods subsequent to the adoption. The Partnership adopted this ASU for its annual goodwillimpairment test in the fourth quarter of 2017.ASU 2017-12In August 2017, the FASB issued ASU No. 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.”The amendments in this update improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk managementactivities in its financial statements. In addition, the amendments in this update103 Table of Contentsmake certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This ASU is effective for financialstatements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. ThePartnership is currently evaluating the impact that adopting this new standard will have on the consolidated financial statements and related disclosures.Estimates and Critical Accounting PoliciesThe selection and application of accounting policies is an important process that has developed as our business activities have evolved and as theaccounting rules have developed. Accounting rules generally do not involve a selection among alternatives, but involve an implementation andinterpretation of existing rules, and the use of judgment applied to the specific set of circumstances existing in our business. We make every effort to properlycomply with all applicable rules, and we believe the proper implementation and consistent application of the accounting rules are critical. Our criticalaccounting policies are discussed below. For further details on our accounting policies see Note 2 to our consolidated financial statements.Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect thereported amounts of assets and liabilities and the accrual for and disclosure of contingent assets and liabilities at the date of the financial statements and thereported amounts of revenues and expenses during the reporting period. The natural gas industry conducts its business by processing actual transactions atthe end of the month following the month of delivery. Consequently, the most current month’s financial results for the midstream, NGL and intrastatetransportation and storage segments are estimated using volume estimates and market prices. Any differences between estimated results and actual results arerecognized in the following month’s financial statements. Management believes that the operating results estimated for the year ended December 31, 2017represent the actual results in all material respects.Some of the other significant estimates made by management include, but are not limited to, the timing of certain forecasted transactions that are hedged, thefair value of derivative instruments, useful lives for depreciation, depletion and amortization, purchase accounting allocations and subsequent realizability ofintangible assets, fair value measurements used in the goodwill impairment test, market value of inventory, assets and liabilities resulting from the regulatedratemaking process, contingency reserves and environmental reserves. Actual results could differ from those estimates.Revenue Recognition. Revenues for sales of natural gas and NGLs are recognized at the later of the time of delivery of the product to the customer or thetime of sale. Revenues from service labor, transportation, treating, compression and gas processing, are recognized upon completion of the service.Transportation capacity payments are recognized when earned in the period the capacity is made available.Our intrastate transportation and storage and interstate transportation and storage segments’ results are determined primarily by the amount of capacity ourcustomers reserve as well as the actual volume of natural gas that flows through the transportation pipelines. Under transportation contracts, our customers arecharged (i) a demand fee, which is a fixed fee for the reservation of an agreed amount of capacity on the transportation pipeline for a specified period of timeand which obligates the customer to pay even if the customer does not transport natural gas on the respective pipeline, (ii) a transportation fee, which is basedon the actual throughput of natural gas by the customer, (iii) fuel retention based on a percentage of gas transported on the pipeline, or (iv) a combination ofthe three, generally payable monthly. Excess fuel retained after consumption is typically valued at market prices.Our intrastate transportation and storage segment also generates revenues and margin from the sale of natural gas to electric utilities, independent powerplants, local distribution companies, industrial end-users and other marketing companies on the HPL System. Generally, we purchase natural gas from themarket, including purchases from our marketing operations, and from producers at the wellhead.In addition, our intrastate transportation and storage segment generates revenues and margin from fees charged for storing customers’ working natural gas inour storage facilities. We also engage in natural gas storage transactions in which we seek to find and profit from pricing differences that occur over timeutilizing the Bammel storage reservoir. We purchase physical natural gas and then sell financial contracts at a price sufficient to cover our carrying costs andprovide for a gross profit margin. We expect margins from natural gas storage transactions to be higher during the periods from November to March of eachyear and lower during the period from April through October of each year due to the increased demand for natural gas during colder weather. However, wecannot assure that management’s expectations will be fully realized in the future and in what time period, due to various factors including weather,availability of natural gas in regions in which we operate, competitive factors in the energy industry, and other issues.Results from the midstream segment are determined primarily by the volumes of natural gas gathered, compressed, treated, processed, purchased and soldthrough our pipeline and gathering systems and the level of natural gas and NGL prices. We generate midstream revenues and segment margins principallyunder fee-based or other arrangements in which we receive a fee for natural104 Table of Contentsgas gathering, compressing, treating or processing services. The revenue earned from these arrangements is directly related to the volume of natural gas thatflows through our systems and is not directly dependent on commodity prices.We also utilize other types of arrangements in our midstream segment, including (i) discount-to-index price arrangements, which involve purchases of naturalgas at either (1) a percentage discount to a specified index price, (2) a specified index price less a fixed amount or (3) a percentage discount to a specifiedindex price less an additional fixed amount, (ii) percentage-of-proceeds arrangements under which we gather and process natural gas on behalf of producers,sell the resulting residue gas and NGL volumes at market prices and remit to producers an agreed upon percentage of the proceeds based on an index price,and (iii) keep-whole arrangements where we gather natural gas from the producer, process the natural gas and sell the resulting NGLs to third parties at marketprices. In many cases, we provide services under contracts that contain a combination of more than one of the arrangements described above. The terms of ourcontracts vary based on gas quality conditions, the competitive environment at the time the contracts are signed and customer requirements. Our contract mixmay change as a result of changes in producer preferences, expansion in regions where some types of contracts are more common and other market factors.We conduct marketing activities in which we market the natural gas that flows through our assets, referred to as on-system gas. We also attract othercustomers by marketing volumes of natural gas that do not move through our assets, referred to as off-system gas. For both on-system and off-system gas, wepurchase natural gas from natural gas producers and other supply points and sell that natural gas to utilities, industrial consumers, other marketers andpipeline companies, thereby generating gross margins based upon the difference between the purchase and resale prices.We have a risk management policy that provides for oversight over our marketing activities. These activities are monitored independently by our riskmanagement function and must take place within predefined limits and authorizations. As a result of our use of derivative financial instruments that may notqualify for hedge accounting, the degree of earnings volatility that can occur may be significant, favorably or unfavorably, from period to period. We attemptto manage this volatility through the use of daily position and profit and loss reports provided to senior management and predefined limits andauthorizations set forth in our risk management policy.We inject and hold natural gas in our Bammel storage facility to take advantage of contango markets, when the price of natural gas is higher in the futurethan the current spot price. We use financial derivatives to hedge the natural gas held in connection with these arbitrage opportunities. At the inception of thehedge, we lock in a margin by purchasing gas in the spot market or off peak season and entering a financial contract to lock in the sale price. If we designatethe related financial contract as a fair value hedge for accounting purposes, we value the hedged natural gas inventory at current spot market prices alongwith the financial derivative we use to hedge it. Changes in the spread between the forward natural gas prices designated as fair value hedges and the physicalinventory spot prices result in unrealized gains or losses until the underlying physical gas is withdrawn and the related designated derivatives are settled.Once the gas is withdrawn and the designated derivatives are settled, the previously unrealized gains or losses associated with these positions are realized.Unrealized margins represent the unrealized gains or losses from our derivative instruments using mark-to-market accounting, with changes in the fair valueof our derivatives being recorded directly in earnings. These margins fluctuate based upon changes in the spreads between the physical spot prices andforward natural gas prices. If the spread narrows between the physical and financial prices, we will record unrealized gains or lower unrealized losses. If thespread widens, we will record unrealized losses or lower unrealized gains. Typically, as we enter the winter months, the spread converges so that we recognizein earnings the original locked in spread, either through mark-to-market or the physical withdrawal of natural gas.NGL storage and pipeline transportation revenues are recognized when services are performed or products are delivered, respectively. Fractionation andprocessing revenues are recognized when product is either loaded into a truck or injected into a third-party pipeline, which is when title and risk of loss passto the customer.In our natural gas compression business, revenue is recognized for compressor packages and technical service jobs using the completed contract methodwhich recognizes revenue upon completion of the job. Costs incurred on a job are deducted at the time revenue is recognized.Terminalling and storage revenues are recognized at the time the services are provided. Pipeline revenues are recognized upon delivery of the barrels to thelocation designated by the shipper. Crude oil acquisition and marketing revenues, as well as refined product marketing revenues, are recognized when title tothe product is transferred to the customer. Revenues are not recognized for crude oil exchange transactions, which are entered into primarily to acquire crudeoil of a desired quality or to reduce transportation costs by taking delivery closer to end markets. Any net differential for exchange transactions is recorded asan adjustment of inventory costs in the purchases component of cost of products sold and operating expenses in the statements of operations.Regulatory Assets and Liabilities. Our interstate transportation and storage segment is subject to regulation by certain state and federal authorities, andcertain subsidiaries in that segment have accounting policies that conform to the accounting requirements105 Table of Contentsand ratemaking practices of the regulatory authorities. The application of these accounting policies allows certain of our regulated entities to defer expensesand revenues on the balance sheet as regulatory assets and liabilities when it is probable that those expenses and revenues will be allowed in the ratemakingprocess in a period different from the period in which they would have been reflected in the consolidated statement of operations by an unregulatedcompany. These deferred assets and liabilities will be reported in results of operations in the period in which the same amounts are included in rates andrecovered from or refunded to customers. Management’s assessment of the probability of recovery or pass through of regulatory assets and liabilities willrequire judgment and interpretation of laws and regulatory commission orders. If, for any reason, we cease to meet the criteria for application of regulatoryaccounting treatment for all or part of our operations, the regulatory assets and liabilities related to those portions ceasing to meet such criteria would beassessed and potentially eliminated from the consolidated balance sheet for the period in which the discontinuance of regulatory accounting treatmentoccurs.Accounting for Derivative Instruments and Hedging Activities. We utilize various exchange-traded and over-the-counter commodity financial instrumentcontracts to limit our exposure to margin fluctuations in natural gas, NGL and refined products. These contracts consist primarily of futures and swaps. Inaddition, prior to the contribution of our retail propane activities to AmeriGas, we used derivatives to limit our exposure to propane market prices.If we designate a derivative financial instrument as a cash flow hedge and it qualifies for hedge accounting, the change in the fair value is deferred in AOCIuntil the underlying hedged transaction occurs. Any ineffective portion of a cash flow hedge’s change in fair value is recognized each period in earnings.Gains and losses deferred in AOCI related to cash flow hedges remain in AOCI until the underlying physical transaction occurs, unless it is probable that theforecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period of time thereafter. Forfinancial derivative instruments that do not qualify for hedge accounting, the change in fair value is recorded in cost of products sold in the consolidatedstatements of operations.If we designate a hedging relationship as a fair value hedge, we record the changes in fair value of the hedged asset or liability in cost of products sold in ourconsolidated statement of operations. This amount is offset by the changes in fair value of the related hedging instrument. Any ineffective portion or amountexcluded from the assessment of hedge ineffectiveness is also included in the cost of products sold in the consolidated statement of operations.We utilize published settlement prices for exchange-traded contracts, quotes provided by brokers, and estimates of market prices based on daily contractactivity to estimate the fair value of these contracts. Changes in the methods used to determine the fair value of these contracts could have a material effect onour results of operations. We do not anticipate future changes in the methods used to determine the fair value of these derivative contracts. See “Item 7A.Quantitative and Qualitative Disclosures about Market Risk” for further discussion regarding our derivative activities.Fair Value of Financial Instruments. We have commodity derivatives, interest rate derivatives and embedded derivatives in our preferred units that areaccounted for as assets and liabilities at fair value in our consolidated balance sheets. We determine the fair value of our assets and liabilities subject to fairvalue measurement by using the highest possible “level” of inputs. Level 1 inputs are observable quotes in an active market for identical assets andliabilities. We consider the valuation of marketable securities and commodity derivatives transacted through a clearing broker with a published price fromthe appropriate exchange as a Level 1 valuation. Level 2 inputs are inputs observable for similar assets and liabilities. We consider OTC commodityderivatives entered into directly with third parties as a Level 2 valuation since the values of these derivatives are quoted on an exchange for similartransactions. Additionally, we consider our options transacted through our clearing broker as having Level 2 inputs due to the level of activity of thesecontracts on the exchange in which they trade. We consider the valuation of our interest rate derivatives as Level 2 as the primary input, the LIBOR curve, isbased on quotes from an active exchange of Eurodollar futures for the same period as the future interest swap settlements. Level 3 inputs are unobservable.Derivatives related to the embedded derivatives in our preferred units are valued using a binomial lattice model. The market inputs utilized in the modelinclude credit spread, probabilities of the occurrence of certain events, common unit price, dividend yield, and expected value, and are considered level 3.See further information on our fair value assets and liabilities in Note 2 of our consolidated financial statements.Impairment of Long-Lived Assets, Goodwill, Intangible Assets and Investments in Unconsolidated Affiliates. Long-lived assets are required to be tested forrecoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Goodwill and intangibleswith indefinite lives must be tested for impairment annually or more frequently if events or changes in circumstances indicate that the related asset might beimpaired. An impairment of an investment in an unconsolidated affiliate is recognized when circumstances indicate that a decline in the investment value isother than temporary. An impairment loss should be recognized only if the carrying amount of the asset/goodwill is not recoverable and exceeds its fairvalue.106 Table of ContentsIn order to test for recoverability when performing a quantitative impairment test, we must make estimates of projected cash flows related to the asset, whichinclude, but are not limited to, assumptions about the use or disposition of the asset, estimated remaining life of the asset, and future expenditures necessaryto maintain the asset’s existing service potential. In order to determine fair value, we make certain estimates and assumptions, including, among other things,changes in general economic conditions in regions in which our markets are located, the availability and prices of natural gas, our ability to negotiatefavorable sales agreements, the risks that natural gas exploration and production activities will not occur or be successful, our dependence on certainsignificant customers and producers of natural gas, and competition from other companies, including major energy producers. While we believe we havemade reasonable assumptions to calculate the fair value, if future results are not consistent with our estimates, we could be exposed to future impairmentlosses that could be material to our results of operations.The Partnership determined the fair value of its reporting units using a weighted combination of the discounted cash flow method and the guideline companymethod. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimates andassumptions include revenue growth rates, operating margins, weighted average costs of capital and future market conditions, among others. The Partnershipbelieves the estimates and assumptions used in our impairment assessments are reasonable and based on available market information, but variations in anyof the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under thediscounted cash flow method, the Partnership determined fair value based on estimated future cash flows of each reporting unit including estimates for capitalexpenditures, discounted to present value using the risk-adjusted industry rate, which reflect the overall level of inherent risk of the reporting unit. Cash flowprojections are derived from one year budgeted amounts and five year operating forecasts plus an estimate of later period cash flows, all of which areevaluated by management. Subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonablylikely to occur. Under the guideline company method, the Partnership determined the estimated fair value of each of our reporting units by applyingvaluation multiples of comparable publicly-traded companies to each reporting unit’s projected EBITDA and then averaging that estimate with similarhistorical calculations using a three year average. In addition, the Partnership estimated a reasonable control premium representing the incremental value thataccrues to the majority owner from the opportunity to dictate the strategic and operational actions of the business.One key assumption for the measurement of an impairment is management’s estimate of future cash flows and EBITDA. These estimates are based on theannual budget for the upcoming year and forecasted amounts for multiple subsequent years. The annual budget process is typically completed near theannual goodwill impairment testing date, and management uses the most recent information for the annual impairment tests. The forecast is also subjected toa comprehensive update annually in conjunction with the annual budget process and is revised periodically to reflect new information and/or revisedexpectations. The estimates of future cash flows and EBITDA are subjective in nature and are subject to impacts from the business risks described in “Item1A. Risk Factors.” Therefore, the actual results could differ significantly from the amounts used for goodwill impairment testing, and significant changes infair value estimates could occur in a given period. Such changes in fair value estimates could result in additional impairments in future periods; however,management does not believe that any of the goodwill balances in its reporting units as of December 31, 2017 is at significant risk of impairment. Therefore,the actual results could differ significantly from the amounts used for goodwill impairment testing, and significant changes in fair value estimates couldoccur in a given period, resulting in additional impairments. Management does not believe that any of the goodwill balances in its reporting units is currently at significant risk of impairment; however, of the $3.1billion of goodwill on the Partnership’s consolidated balance sheet as of December 31, 2017, approximately $1.0 billion is recorded in reporting units forwhich the estimated fair value exceeded the carrying value by less than 20% in the most recent quantitative test.During the year ended December 31, 2017, the Partnership recorded following impairments:•A $223 million impairment was recorded related to the goodwill associated with CDM. In January 2018, the Partnership announced the contribution ofCDM to USAC. Based on the Partnership’s anticipated proceeds in the contribution transaction, the implied fair value of the CDM reporting unit was lessthan the Partnership’s carrying value. As the Partnership believes that the contribution consideration also represented an appropriate estimate of fairvalue as of the 2017 annual impairment test date, the Partnership recorded an impairment for the difference between the carrying value and the fair valueof the reporting unit. Subsequent to the impairment, a total of $253 million of goodwill remains in the CDM reporting unit, which amount is subject tofurther impairment based on changes in the contribution transaction prior to closing or any other factors affecting the fair value of the CDM reportingunit. Assuming the contribution transaction closes, the remaining CDM goodwill balance will be derecognized; if the transaction does not close, thenthe CDM goodwill balance will remain on the Partnership’s consolidated balance sheet and will continue to be tested for impairment in the future.•A $262 million impairment was recorded related to the goodwill associated with the Partnership’s interstate transportation and storage reporting units,and a $229 million impairment was recorded related to the goodwill associated with the general partner of Panhandle in the all other segment. Theseimpairments were due to a reduction in management’s forecasted future107 Table of Contentscash flows from the related reporting units, which reduction reflected the impacts discussed in “Results of Operations” above, along with the impacts ofre-contracting assumptions related to future periods.•A $79 million impairment was recorded related to the goodwill associated the Partnership’s refined products transportation and services reporting unit.Subsequent to the Sunoco Logistics Merger, the Partnership restructured the internal reporting of legacy Sunoco Logistics’ business to be consistent withthe internal reporting of legacy ETP. Subsequent to this reallocation the carrying value of certain refined products reporting units was less than theestimated fair value due to a reduction in management’s forecasted future cash flows from the related reporting units, and the goodwill associated withthose reporting units was fully impaired. No goodwill remained in the respective reporting units subsequent to the impairment.•A $127 million impairment of property, plant and equipment related to Sea Robin primarily due to a reduction in expected future cash flows due to anincrease during 2017 in insurance costs related to offshore assets.•A $141 million impairment of the Partnership’s equity method investment in FEP. The Partnership concluded that the carrying value of its investment inFEP was other than temporarily impaired based on an anticipated decrease in production in the Fayetteville basin and a customer re-contracting with acompetitor during 2017.•A $172 million impairment of the Partnership’s equity method investment in HPC primarily due to a decrease in projected future revenues and cash flowsdriven be the bankruptcy of one of HPC’s major customers in 2017 and an expectation that contracts expiring in the next few years will be renewed atlower tariff rates and lower volumes.During the year ended December 31, 2016, the Partnership recorded following goodwill impairments:•A $638 million goodwill impairment and a $133 million impairment to property, plant and equipment were recorded in the interstate transportation andstorage segment primarily due to decreases in projected future revenues and cash flows driven by changes in the markets that these assets serve.•A $32 million goodwill impairment was recorded in the midstream segment primarily due to decreases in projected future revenues and cash flows drivenby declines in commodity prices.•A $308 million impairment of the Partnership’s equity method investment in MEP. The Partnership concluded that the carrying value of its investmentin MEP was other than temporarily impaired based on commercial discussions with current and potential shippers on MEP during 2016, whichnegatively affected the outlook for long-term transportation contract rates.During the year ended December 31, 2015, the Partnership recorded following goodwill impairments:•A $99 million goodwill impairment related to Transwestern primarily due to market declines in current and expected future commodity prices in thefourth quarter of 2015.•A $106 million goodwill impairment, a $24 million impairment of intangible assets, and a $110 million impairment to property, plant and equipmentrelated to Lone Star Refinery Services primarily due to changes in assumptions related to potential future revenues and market declines in current andexpected future commodity prices, as well as economic obsolescence identified as a result of low utilization.Except for the 2017 impairment of the goodwill associated with CDM, as discussed above, the goodwill impairments recorded by the Partnership during theyears ended December 31, 2017, 2016 and 2015 represented all of the goodwill within the respective reporting units.Property, Plant and Equipment. Expenditures for maintenance and repairs that do not add capacity or extend the useful life are expensed as incurred.Expenditures to refurbish assets that either extend the useful lives of the asset or prevent environmental contamination are capitalized and depreciated overthe remaining useful life of the asset. Additionally, we capitalize certain costs directly related to the construction of assets including internal labor costs,interest and engineering costs. Upon disposition or retirement of pipeline components or natural gas plant components, any gain or loss is recorded toaccumulated depreciation. When entire pipeline systems, gas plants or other property and equipment are retired or sold, any gain or loss is included in theconsolidated statement of operations. Depreciation of property, plant and equipment is provided using the straight-line method based on their estimateduseful lives ranging from 1 to 99 years. Changes in the estimated useful lives of the assets could have a material effect on our results of operation. We do notanticipate future changes in the estimated useful lives of our property, plant and equipment.Asset Retirement Obligations. We have determined that we are obligated by contractual or regulatory requirements to remove facilities or perform otherremediation upon retirement of certain assets. The fair value of any ARO is determined based on estimates and assumptions related to retirement costs, whichthe Partnership bases on historical retirement costs, future inflation rates and credit-adjusted risk-free interest rates. These fair value assessments areconsidered to be Level 3 measurements, as they108 Table of Contentsare based on both observable and unobservable inputs. Changes in the liability are recorded for the passage of time (accretion) or for revisions to cash flowsoriginally estimated to settle the ARO.An ARO is required to be recorded when a legal obligation to retire an asset exists and such obligation can be reasonably estimated. We will record an assetretirement obligation in the periods in which management can reasonably estimate the settlement dates.Except for certain amounts discussed below, management was not able to reasonably measure the fair value of asset retirement obligations as of December 31,2017 and 2016, in most cases because the settlement dates were indeterminable. Although a number of other onshore assets in Panhandle’s system are subjectto agreements or regulations that give rise to an ARO upon Panhandle’s discontinued use of these assets, AROs were not recorded because these assets havean indeterminate removal or abandonment date given the expected continued use of the assets with proper maintenance or replacement. Sunoco, Inc. haslegal asset retirement obligations for several other assets at its previously owned refineries, pipelines and terminals, for which it is not possible to estimatewhen the obligations will be settled. Consequently, the retirement obligations for these assets cannot be measured at this time. At the end of the useful life ofthese underlying assets, Sunoco, Inc. is legally or contractually required to abandon in place or remove the asset. We believe we may have additional assetretirement obligations related to its pipeline assets and storage tanks, for which it is not possible to estimate whether or when the retirement obligations willbe settled. Consequently, these retirement obligations cannot be measured at this time.Individual component assets have been and will continue to be replaced, but the pipeline and the natural gas gathering and processing systems will continuein operation as long as supply and demand for natural gas exists. Based on the widespread use of natural gas in industrial and power generation activities,management expects supply and demand to exist for the foreseeable future. We have in place a rigorous repair and maintenance program that keeps thepipelines and the natural gas gathering and processing systems in good working order. Therefore, although some of the individual assets may be replaced, thepipelines and the natural gas gathering and processing systems themselves will remain intact indefinitely.Long-lived assets related to AROs aggregated $2 million and $14 million, and were reflected as property, plant and equipment on our balance sheet as ofDecember 31, 2017 and 2016, respectively. In addition, the Partnership had $21 million and $13 million of legally restricted funds for the purpose of settlingAROs that was reflected as other non-current assets as of December 31, 2017 and 2016, respectively.Pensions and Other Postretirement Benefit Plans. We are required to measure plan assets and benefit obligations as of its fiscal year-end balance sheet date.We recognize the changes in the funded status of our defined benefit postretirement plans through AOCI or are reflected as a regulatory asset or regulatoryliability for regulated subsidiaries.The calculation of the net periodic benefit cost and benefit obligation requires the use of a number of assumptions. Changes in these assumptions can have asignificant effect on the amounts reported in the financial statements. The Partnership believes that the two most critical assumptions are the assumeddiscount rate and the expected rate of return on plan assets.The discount rate is established by using a hypothetical portfolio of high-quality debt instruments that would provide the necessary cash flows to pay thebenefits when due. Net periodic benefit cost and benefit obligation increases and equity correspondingly decreases as the discount rate is reduced.The expected rate of return on plan assets is based on long-term expectations given current investment objectives and historical results. Net periodic benefitcost increases as the expected rate of return on plan assets is correspondingly reduced.Legal Matters. We are subject to litigation and regulatory proceedings as a result of our business operations and transactions. We utilize both internal andexternal counsel in evaluating our potential exposure to adverse outcomes from claims, orders, judgments or settlements. To the extent that actual outcomesdiffer from our estimates, or additional facts and circumstances cause us to revise our estimates, our earnings will be affected. We expense legal costs asincurred, and all recorded legal liabilities are revised, as required, as better information becomes available to us. The factors we consider when recording anaccrual for contingencies include, among others: (i) the opinions and views of our legal counsel; (ii) our previous experience; and (iii) the decision of ourmanagement as to how we intend to respond to the complaints.For more information on our litigation and contingencies, see Note 11 to our consolidated financial statements included in “Item 8. Financial Statements andSupplementary Data” in this report.Environmental Remediation Activities. The Partnership’s accrual for environmental remediation activities reflects anticipated work at identified sites wherean assessment has indicated that cleanup costs are probable and reasonably estimable. The accrual for known claims is undiscounted and is based oncurrently available information, estimated timing of remedial actions and related inflation assumptions, existing technology and presently enacted laws andregulations. It is often extremely difficult to develop reasonable estimates of future site remediation costs due to changing regulations, changingtechnologies and their associated costs,109 Table of Contentsand changes in the economic environment. Engineering studies, historical experience and other factors are used to identify and evaluate remediationalternatives and their related costs in determining the estimated accruals for environmental remediation activities.Losses attributable to unasserted claims are generally reflected in the accruals on an undiscounted basis, to the extent they are probable of occurrence andreasonably estimable. We have established a wholly-owned captive insurance company to bear certain risks associated with environmental obligationsrelated to certain sites that are no longer operating. The premiums paid to the captive insurance company include estimates for environmental claims thathave been incurred but not reported, based on an actuarially determined fully developed claims expense estimate. In such cases, we accrue losses attributableto unasserted claims based on the discounted estimates that are used to develop the premiums paid to the captive insurance company.In general, each remediation site/issue is evaluated individually based upon information available for the site/issue and no pooling or statistical analysis isused to evaluate an aggregate risk for a group of similar items (e.g., service station sites) in determining the amount of probable loss accrual to be recorded.The Partnership’s estimates of environmental remediation costs also frequently involve evaluation of a range of estimates. In many cases, it is difficult todetermine that one point in the range of loss estimates is more likely than any other. In these situations, existing accounting guidance requires that theminimum of the range be accrued. Accordingly, the low end of the range often represents the amount of loss which has been recorded.In addition to the probable and estimable losses which have been recorded, management believes it is reasonably possible (i.e., less than probable but greaterthan remote) that additional environmental remediation losses will be incurred. At December 31, 2017, the aggregate of the estimated maximum reasonablypossible losses, which relate to numerous individual sites, totaled approximately $5 million. This estimate of reasonably possible losses comprises estimatesfor remediation activities at current logistics and retail assets and, in many cases, reflects the upper end of the loss ranges which are described above. Suchestimates include potentially higher contractor costs for expected remediation activities, the potential need to use more costly or comprehensive remediationmethods and longer operating and monitoring periods, among other things.Total future costs for environmental remediation activities will depend upon, among other things, the identification of any additional sites, the determinationof the extent of the contamination at each site, the timing and nature of required remedial actions, the nature of operations at each site, the technologyavailable and needed to meet the various existing legal requirements, the nature and terms of cost-sharing arrangements with other potentially responsibleparties, the availability of insurance coverage, the nature and extent of future environmental laws and regulations, inflation rates, terms of consent agreementsor remediation permits with regulatory agencies and the determination of the Partnership’s liability at the sites, if any, in light of the number, participationlevel and financial viability of the other parties. The recognition of additional losses, if and when they were to occur, would likely extend over many years.Management believes that the Partnership’s exposure to adverse developments with respect to any individual site is not expected to be material. However, ifchanges in environmental laws or regulations occur or the assumptions used to estimate losses at multiple sites are adjusted, such changes could impactmultiple facilities, formerly owned facilities and third-party sites at the same time. As a result, from time to time, significant charges against income forenvironmental remediation may occur; however, management does not believe that any such charges would have a material adverse impact on thePartnership’s consolidated financial position.Deferred Income Taxes. ETP recognizes benefits in earnings and related deferred tax assets for net operating loss carryforwards (“NOLs”) and tax creditcarryforwards. If necessary, a charge to earnings and a related valuation allowance are recorded to reduce deferred tax assets to an amount that is more likelythan not to be realized by the Partnership in the future. Deferred income tax assets attributable to state and federal NOLs and federal tax alternative minimumtax credit carryforwards totaling $604 million have been included in ETP’s consolidated balance sheet as of December 31, 2017. All of the deferred incometax assets attributable to state and federal NOL benefits expire before 2037 as more fully described below. The state NOL carryforward benefits of$266 million ($210 million net of federal benefit) begin to expire in 2018 with a substantial portion expiring between 2031 and 2037. The federal NOLs of$1.57 billion ($331 million in benefits) will expire in 2031 and 2037. Federal alternative minimum tax credit carryforwards of $62 million remained atDecember 31, 2017. We have determined that a valuation allowance totaling $236 million ($186 million net of federal income tax effects) is required for thestate NOLs at December 31, 2017 primarily due to significant restrictions on their use in the Commonwealth of Pennsylvania. In making the assessment of thefuture realization of the deferred tax assets, we rely on future reversals of existing taxable temporary differences, tax planning strategies and forecastedtaxable income based on historical and projected future operating results. The potential need for valuation allowances is regularly reviewed by management.If it is more likely than not that the recorded asset will not be realized, additional valuation allowances which increase income tax expense may berecognized in the period such determination is made. Likewise, if it is more likely than not that additional deferred tax assets will be realized, an adjustmentto the deferred tax asset will increase income in the period such determination is made.110 Table of ContentsForward-Looking StatementsThis annual report contains various forward-looking statements and information that are based on our beliefs and those of our General Partner, as well asassumptions made by and information currently available to us. These forward-looking statements are identified as any statement that does not relate strictlyto historical or current facts. When used in this annual report, words such as “anticipate,” “project,” “expect,” “plan,” “goal,” “forecast,” “estimate,” “intend,”“could,” “believe,” “may,” “will” and similar expressions and statements regarding our plans and objectives for future operations, are intended to identifyforward-looking statements. Although we and our General Partner believe that the expectations on which such forward-looking statements are based arereasonable, neither we nor our General Partner can give assurances that such expectations will prove to be correct. Forward-looking statements are subject to avariety of risks, uncertainties and assumptions. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, ouractual results may vary materially from those anticipated, estimated, projected or expected. Among the key risk factors that may have a direct bearing on ourresults of operations and financial condition are:•the volumes transported on our pipelines and gathering systems;•the level of throughput in our processing and treating facilities;•the fees we charge and the margins we realize for our gathering, treating, processing, storage and transportation services;•the prices and market demand for, and the relationship between, natural gas and NGLs;•energy prices generally;•the prices of natural gas and NGLs compared to the price of alternative and competing fuels;•the general level of petroleum product demand and the availability and price of NGL supplies;•the level of domestic oil, natural gas and NGL production;•the availability of imported oil, natural gas and NGLs;•actions taken by foreign oil and gas producing nations;•the political and economic stability of petroleum producing nations;•the effect of weather conditions on demand for oil, natural gas and NGLs;•availability of local, intrastate and interstate transportation systems;•the continued ability to find and contract for new sources of natural gas supply;•availability and marketing of competitive fuels;•the impact of energy conservation efforts;•energy efficiencies and technological trends;•governmental regulation and taxation;•changes to, and the application of, regulation of tariff rates and operational requirements related to our interstate and intrastate pipelines;•hazards or operating risks incidental to the gathering, treating, processing and transporting of natural gas and NGLs;•competition from other midstream companies and interstate pipeline companies;•loss of key personnel;•loss of key natural gas producers or the providers of fractionation services;•reductions in the capacity or allocations of third-party pipelines that connect with our pipelines and facilities;•the effectiveness of risk-management policies and procedures and the ability of our liquids marketing counterparties to satisfy their financialcommitments;•the nonpayment or nonperformance by our customers;•regulatory, environmental, political and legal uncertainties that may affect the timing and cost of our internal growth projects, such as our constructionof additional pipeline systems;111 Table of Contents•risks associated with the construction of new pipelines and treating and processing facilities or additions to our existing pipelines and facilities,including difficulties in obtaining permits and rights-of-way or other regulatory approvals and the performance by third-party contractors;•the availability and cost of capital and our ability to access certain capital sources;•a deterioration of the credit and capital markets;•risks associated with the assets and operations of entities in which we own less than a controlling interests, including risks related to management actionsat such entities that we may not be able to control or exert influence;•the ability to successfully identify and consummate strategic acquisitions at purchase prices that are accretive to our financial results and to successfullyintegrate acquired businesses;•changes in laws and regulations to which we are subject, including tax, environmental, transportation and employment regulations or new interpretationsby regulatory agencies concerning such laws and regulations; and•the costs and effects of legal and administrative proceedings.You should not put undue reliance on any forward-looking statements. When considering forward-looking statements, please review the risks describedunder “Item 1A. Risk Factors” in this annual report. Any forward-looking statement made by us in this Annual Report on Form 10-K is based only oninformation currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-lookingstatement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.InflationInterest rates on existing and future credit facilities and future debt offerings could be significantly higher than current levels, causing our financing costs toincrease accordingly. Although increased financing costs could limit our ability to raise funds in the capital markets, we expect to remain competitive withrespect to acquisitions and capital projects since our competitors would face similar circumstances.Inflation in the United States has been relatively low in recent years and has not had a material effect on our results of operations. It may in the future,however, increase the cost to acquire or replace property, plant and equipment and may increase the costs of labor and supplies. Our operating revenues andcosts are influenced to a greater extent by commodity price changes. To the extent permitted by competition, regulation and our existing agreements, wehave and will continue to pass along a portion of increased costs to our customers in the form of higher fees.ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKWe are exposed to market risks related to the volatility of commodity prices. To manage the impact of volatility from these prices, we utilize variousexchange-traded and OTC commodity financial instrument contracts. These contracts consist primarily of futures, swaps and options and are recorded at fairvalue in our consolidated balance sheets.We use futures and basis swaps, designated as fair value hedges, to hedge our natural gas inventory stored in our Bammel storage facility. At hedge inception,we lock in a margin by purchasing gas in the spot market or off peak season and entering into a financial contract. Changes in the spreads between theforward natural gas prices and the physical inventory spot price result in unrealized gains or losses until the underlying physical gas is withdrawn and therelated designated derivatives are settled. Once the gas is withdrawn and the designated derivatives are settled, the previously unrealized gains or lossesassociated with these positions are realized.We use futures, swaps and options to hedge the sales price of natural gas we retain for fees in our intrastate transportation and storage segment andoperational gas sales on our interstate transportation and storage segment. These contracts are not designated as hedges for accounting purposes.We use NGL and crude derivative swap contracts to hedge forecasted sales of NGL and condensate equity volumes we retain for fees in our midstreamsegment whereby our subsidiaries generally gather and process natural gas on behalf of producers, sell the resulting residue gas and NGL volumes at marketprices and remit to producers an agreed upon percentage of the proceeds based on an index price for the residue gas and NGL. These contracts are notdesignated as hedges for accounting purposes.We utilize swaps, futures and other derivative instruments to mitigate the risk associated with market movements in the price of refined products and NGLs tomanage our storage facilities and the purchase and sale of purity NGL. These contracts are not designated as hedges for accounting purposes.112 Table of ContentsWe use financial commodity derivatives to take advantage of market opportunities in our trading activities which complement our transportation and storagesegment’s operations and are netted in cost of products sold in our consolidated statements of operations. We also have trading and marketing activitiesrelated to power and natural gas in our all other segment which are also netted in cost of products sold. As a result of our trading activities and the use ofderivative financial instruments in our transportation and storage segment, the degree of earnings volatility that can occur may be significant, favorably orunfavorably, from period to period. We attempt to manage this volatility through the use of daily position and profit and loss reports provided to our riskoversight committee, which includes members of senior management, and the limits and authorizations set forth in our commodity risk management policy.The table below summarizes our commodity-related financial derivative instruments and fair values, including derivatives related to our consolidatedsubsidiaries, as well as the effect of an assumed hypothetical 10% change in the underlying price of the commodity.

Non-trading positions offset physical exposures to the cash market; none of these offsetting physical exposures areincluded in the above tables. Price-risk sensitivities were calculated by assuming a theoretical 10% change (increase or decrease) in price regardless of term orhistorical relationships between the contractual price of the instruments and the underlying commodity price. Results are presented in absolute terms andrepresent a potential gain or loss in net income or in other comprehensive income. In the event of an actual 10% change in prompt month113 Table of Contentsnatural gas prices, the fair value of our total derivative portfolio may not change by 10% due to factors such as when the financial instrument settles and thelocation to which the financial instrument is tied (i.e., basis swaps) and the relationship between prompt month and forward months.Interest Rate RiskAs of December 31, 2017, we had $5.11 billion of floating rate debt outstanding. A hypothetical change of 100 basis points would result in a maximumpotential change to interest expense of $51 million annually; however, our actual change in interest expense may be less in a given period due to interest ratefloors included in our variable rate debt instruments. We manage a portion of our interest rate exposure by utilizing interest rate swaps, including forward-starting interest rate swaps to lock-in the rate on a portion of anticipated debt issuances.The following table summarizes our interest rate swaps outstanding, none of which were designated as hedges for accounting purposes:Term Type(1) Notional Amount OutstandingDecember 31, 2017 December 31, 2016July 2017(2) Forward-starting to pay a fixed rate of 3.90% and receive a floating rate $— $500July 2018(2) Forward-starting to pay a fixed rate of 3.76% and receive a floating rate 300 200July 2019(2) Forward-starting to pay a fixed rate of 3.64% and receive a floating rate 300 200July 2020(2) Forward-starting to pay a fixed rate of 3.52% and receive a floating rate 400 —December 2018 Pay a floating rate based on a 3-month LIBOR and receive a fixed rate of 1.53% 1,200 1,200March 2019 Pay a floating rate based on a 3-month LIBOR and receive a fixed rate of 1.42% 300 300(1) Floating rates are based on 3-month LIBOR. (2) Represents the effective date. These forward-starting swaps have terms of 30 years with a mandatory termination date the same as the effective date. A hypothetical change of 100 basis points in interest rates for these interest rate swaps would result in a net change in the fair value of interest rate derivativesand earnings (recognized in gains and losses on interest rate derivatives) of $236 million as of December 31, 2017. For the $1.50 billion of interest rate swapswhereby we pay a floating rate and receive a fixed rate, a hypothetical change of 100 basis points in interest rates would result in a net change in annual cashflows of $15 million. For the forward-starting interest rate swaps, a hypothetical change of 100 basis points in interest rates would not affect cash flows untilthe swaps are settled.Credit RiskCredit risk refers to the risk that a counterparty may default on its contractual obligations resulting in a loss to the Partnership. Credit policies have beenapproved and implemented to govern the Partnership’s portfolio of counterparties with the objective of mitigating credit losses. These policies establishguidelines, controls and limits to manage credit risk within approved tolerances by mandating an appropriate evaluation of the financial condition ofexisting and potential counterparties, monitoring agency credit ratings, and by implementing credit practices that limit exposure according to the riskprofiles of the counterparties. Furthermore, the Partnership may, at times, require collateral under certain circumstances to mitigate credit risk as necessary.The Partnership also uses industry standard commercial agreements which allow for the netting of exposures associated with transactions executed under asingle commercial agreement. Additionally, we utilize master netting agreements to offset credit exposure across multiple commercial agreements with asingle counterparty or affiliated group of counterparties.The Partnership’s counterparties consist of a diverse portfolio of customers across the energy industry, including petrochemical companies, commercial andindustrials, oil and gas producers, municipalities, gas and electric utilities, midstream companies and independent power generators. Our overall exposuremay be affected positively or negatively by macroeconomic or regulatory changes that impact our counterparties to one extent or another. Currently,management does not anticipate a material adverse effect in our financial position or results of operations as a consequence of counterparty non-performance.114 Table of ContentsFor financial instruments, failure of a counterparty to perform on a contract could result in our inability to realize amounts that have been recorded on ourconsolidated balance sheets and recognized in net income or other comprehensive income.ITEM 8.

Under the supervision and with the participation of our management, including the ChiefExecutive Officer and Chief Financial Officer of ETP LLC, we conducted an evaluation of the effectiveness of our internal control over financial reportingbased on the framework in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the TreadwayCommission (“COSO framework”).Based on our evaluation under the COSO framework, our management concluded that our internal control over financial reporting was effective as ofDecember 31, 2017.Grant Thornton LLP, an independent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting as ofDecember 31, 2017, as stated in their report, which is included herein.115 Table of ContentsREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMBoard of Directors of Energy Transfer Partners, L.L.C. andUnitholders of Energy Transfer Partners, L.P.Opinion on internal control over financial reportingWe have audited the internal control over financial reporting of Energy Transfer Partners, L.P. (a Delaware limited partnership) and subsidiaries (the“Partnership”) as of December 31, 2017, based on criteria established in the 2013 Internal Control – Integrated Framework issued by the Committee ofSponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Partnership maintained, in all material respects, effective internalcontrol over financial reporting as of December 31, 2017, based on criteria established in the 2013 Internal Control – Integrated Framework issued byCOSO.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidatedfinancial statements of the Partnership as of and for the year ended December 31, 2017, and our report dated February 23, 2018 expressed an unqualifiedopinion on those financial statements.Basis for opinionThe Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness ofinternal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Ourresponsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit.We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S.federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonableassurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining anunderstanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operatingeffectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. Webelieve that our audit provides a reasonable basis for our opinion.Definition and limitations of internal control over financial reportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate./s/ GRANT THORNTON LLPDallas, TexasFebruary 23, 2018116 Table of ContentsChanges in Internal Control over Financial ReportingThere has been no change in our internal control over financial reporting (as defined in Rules 13a–15(f) or Rule 15d–15(f)) that occurred in the three monthsended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.ITEM 9B. OTHER INFORMATIONNone.117 Table of ContentsPART IIIITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCEBoard of DirectorsOur General Partner manages and directs all of our activities. On April 28, 2017, concurrent with the merger of legacy ETP and legacy Sunoco Logistics, thegeneral partner of legacy Sunoco Logistics, Sunoco Partners LLC, merged with and into the general partner of legacy ETP, Energy Transfer Partners GP, L.P.(“ETP GP”), with ETP GP surviving as the new general partner of the Partnership. The activities of ETP GP are managed and directed by its general partner,ETP LLC, which we refer to in this Item as “our General Partner.” Our officers and directors are officers and directors of ETP LLC. ETE, as the sole member ofETP LLC, is entitled under the limited liability company agreement of ETP LLC to appoint all of the directors of ETP LLC. This agreement provides that theBoard of Directors of ETP LLC shall consist of not more than 13 persons, at least three of whom are required to qualify as independent directors. As ofDecember 31, 2017, our Board of Directors was comprised of six persons, three of whom qualified as “independent” under the NYSE’s corporate governancestandards. Our Board of Directors determined that Messrs. Collins, Grimm and Skidmore all met the NYSE’s independence requirements. Our current directorswho are not independent consist of Kelcy L. Warren, ETP LLC’s Chief Executive Officer, and Matthew S. Ramsey, ETP LLC’s President and Chief OperatingOfficer, as well as Marshall S. McCrea III, the Group Chief Operating Officer and Chief Commercial Officer of ETE’s general partner.As a limited partnership, we are not required by the rules of the NYSE to seek Unitholder approval for the election of any of our directors. We believe thatETE has appointed as directors individuals with experience, skills and qualifications relevant to the business of the Partnership, such as experience in energyor related industries or with financial markets, expertise in natural gas operations or finance, and a history of service in senior leadership positions. We do nothave a formal process for identifying director nominees, nor do we have a formal policy regarding consideration of diversity in identifying director nominees,but we believe ETE has endeavored to assemble a group of individuals with the qualities and attributes required to provide effective oversight of thePartnership.Board Leadership Structure. We have no policy requiring either that the positions of the Chairman of the Board and the Chief Executive Officer, or CEO, beseparate or that they be occupied by the same individual. The Board of Directors believes that this issue is properly addressed as part of the successionplanning process and that a determination on this subject should be made when it elects a new chief executive officer or at such other times as whenconsideration of the matter is warranted by circumstances. Currently, the Board of Directors believes that the CEO is best situated to serve as Chairmanbecause he is the director most familiar with the Partnership’s business and industry, and most capable of effectively identifying strategic priorities andleading the discussion and execution of strategy. Independent directors and management have different perspectives and roles in strategy development. Ourindependent directors bring experience, oversight and expertise from outside the Partnership and from a variety of industries, while the CEO brings extensiveexperience and expertise specifically related to the Partnership’s business. The Board of Directors believes that the current combined role of Chairman andCEO promotes strategy development and execution, and facilitates information flow between management and the Board of Directors, which are essential toeffective governance.One of the key responsibilities of the Board of Directors is to develop strategic direction and hold management accountable for the execution of strategyonce it is developed. The Board of Directors believes the current combined role of Chairman and CEO, together with a majority of independent boardmembers, is in the best interest of Unitholders because it provides the appropriate balance between strategy development and independent oversight ofmanagement.Risk Oversight. Our Board of Directors generally administers its risk oversight function through the board as a whole. Our CEO, who reports to the Board ofDirectors, and the other executive officers, who report to our CEO, have day-to-day risk management responsibilities. Each of these executives attends themeetings of our Board of Directors, where the Board of Directors routinely receives reports on our financial results, the status of our operations, and otheraspects of implementation of our business strategy, with ample opportunity for specific inquiries of management. In addition, at each regular meeting of theBoard, management provides a report of the Partnership’s financial and operational performance, which often prompts questions or feedback from the Boardof Directors. The Audit Committee provides additional risk oversight through its quarterly meetings, where it receives a report from the Partnership’s internalauditor, who reports directly to the Audit Committee, and reviews the Partnership’s contingencies with management and our independent auditors.Corporate GovernanceThe Board of Directors has adopted both a Code of Business Conduct and Ethics applicable to our directors, officers and employees, and CorporateGovernance Guidelines for directors and the Board. Current copies of our Code of Business Conduct and Ethics, Corporate Governance Guidelines andcharters of the Audit and Compensation Committees of our Board of Directors are available on our website at www.energytransfer.com and will be providedin print form to any Unitholder requesting such information.118 Table of ContentsPlease note that the preceding Internet address is for information purposes only and is not intended to be a hyperlink.

As a policy matter, the Conflicts Committeegenerally reviews any proposed related-party transaction that may be material to the Partnership to determine if the transaction presents a conflict of interestand whether the transaction is fair and reasonable to the Partnership. Pursuant to the terms of our partnership agreement, any matters approved by theConflicts Committee will be conclusively deemed to be fair and reasonable to the Partnership, approved by all partners of the Partnership and not a breach bythe General Partner or its Board of Directors of any duties they may owe the Partnership or the Unitholders. These duties are limited by our PartnershipAgreement (see “Risks Related to Conflicts of Interest” in “Item 1A.

In addition, the Board determinesthat at least one member of the Audit Committee has such accounting or related financial management expertise sufficient to qualify such person as the auditcommittee financial expert in accordance with Item 407 (d)(5) of Regulation S-K.

EXECUTIVE COMPENSATIONOverviewAs a limited partnership, we are managed by our General Partner, which in turn is managed by its general partner, ETP LLC, which we refer to in this Item as“our General Partner.” As of December 31, 2017, ETE owned 100% of our General Partner, approximately 27.5 million of our outstanding Common Units and100% of our outstanding Class H and Class I Units. All of our employees are employed by and receive employee benefits from our Operating Companies.Effective April 28, 2017, ETP GP replaced SXL GP as the general partner of the former Sunoco Logistics Partners, L.P. (now renamed Energy TransferPartners, L.P.).Compensation Discussion and AnalysisNamed Executive OfficersThe executive officers referred to in this discussion as the “named executive officers” are the following officers with the roles they held for 2017:•Kelcy L. Warren, Chairman and Chief Executive Officer;•Thomas E. Long, Chief Financial Officer and Group Chief Financial Officer of ETE’s general partner;•Marshall S. (Mackie) McCrea, III, Group Chief Operating Officer and Chief Commercial Officer•Matthew S. Ramsey, President and Chief Operating Officer;•James M. Wright, General Counsel and Assistant Secretary;•Michael J. Hennigan, Former President and Chief Executive Officer of Sunoco Partners LLC; and•Peter J. Gvazdauskas, Former Chief Financial Officer and Treasurer of Sunoco Partners LLC.During 2017, Mr. McCrea, Group Chief Operating Officer and Chief Commercial Officer of ETE’s general partner and Mr. Long, as Group Chief FinancialOfficer of ETE’s general partner provided services to each of ETE, ETP (formerly named “Sunoco Logistics Partners L.P.”), Energy Transfer, LP (formerlynamed “Energy Transfer Partners, L.P.”) and, in the case of Mr. Long, Sunoco LP. Decisions with respect to Messrs. McCrea’s and Long’s compensationduring 2017 were made by the ETE Compensation Committee in consultation, as appropriate, with the ETP Compensation Committee or the Energy Transfer,LP Compensation Committee as applicable prior to the Sunoco Logistics Merger.Prior to the Sunoco Logistics Merger in April 2017, Mr. Hennigan’s and Mr. Gvazdauskas’ primary business responsibilities related to Sunoco Logistics andits consolidated subsidiaries. Prior to the Sunoco Logistics Merger, the compensation committee of Sunoco Partners LLC set the components of Mr.Hennigan’s and Mr. Gvazdauskas’ compensation, including salary, long-term incentive awards and annual bonus utilizing the same philosophy andmethodology adopted by our General Partner.Our General Partner’s Philosophy for Compensation of ExecutivesIn general, our General Partner’s executive compensation philosophy is based on the premise that a significant portion of each executive’s compensationshould be incentive-based or “at-risk” compensation and that executives’ total compensation levels should be highly competitive in the marketplace forexecutive talent and abilities. ETP LLC seeks a total compensation program for the named executive officers that provides for a slightly below the medianmarket annual base compensation rate (i.e. approximately the 40th percentile of market) but incentive-based compensation composed of a combination ofcompensation vehicles to reward both short and long-term performance that are both targeted to pay-out at approximately the top-quartile of market. ETPLLC believes the incentive-based balance is achieved by (i) the payment of annual discretionary cash bonuses that consider the achievement of ETP’sfinancial performance objectives for a fiscal year set at the beginning of such fiscal year and the individual contributions of the named executive officers tothe success of ETP and the achievement of the annual financial performance objectives and (ii) the annual grant of time-based restricted unit or phantom unitawards under the equity incentive plan(s), which awards are intended to provide a longer term incentive and retention value to the key employees to focustheir efforts on increasing the market price of the publicly traded units and to increase the cash distribution paid to unitholders.ETP LLC grants restricted unit awards that vest, based generally upon continued employment, at a rate of 60% after the third anniversary of the award and theremaining 40% after the fifth anniversary of the award. ETP LLC believes that these equity-based incentive arrangements are important in attracting andretaining executives, including the named executive officers, and key employees as well as motivating these individuals to achieve business objectives. Theequity-based compensation also reflects the importance of aligning the interests of the executives, including the named executive officers, with those ofETP’s unitholders.124 Table of ContentsWhile ETP is responsible for the direct payment of the compensation of the named executive officers as employees of ETP LLC, ETP or its controlledaffiliates, ETP does not participate or have any input in any decisions as to the compensation policies of ETP LLC or the compensation levels of theexecutive officers of ETP LLC. The compensation committee of the board of directors of ETP LLC (the “ETP Compensation Committee”) is responsible forthe approval of the compensation policies and the compensation levels of these executive officers. ETP directly pays these executive officers in lieu ofreceiving an allocation of overhead related to executive compensation from ETP LLC. For a more detailed description of the compensation of the namedexecutive officers, please see “Compensation Tables” below. Both the ETE Compensation Committee and the compensation committee of Sunoco PartnersLLC (the “Sunoco Logistics Compensation Committee”) follow a substantially similar executive compensation philosophy for executives as the ETPCompensation Committee.Compensation PhilosophyOur compensation program is structured to achieve the following:•reward executives with an industry-competitive total compensation package of targeted base salaries and significant incentive opportunities yielding atotal compensation package approaching the top-quartile of the market;•attract, retain and reward talented executive officers and key management employees by providing total compensation competitive with that of otherexecutive officers and key management employees employed by publicly traded limited partnerships of similar size and in similar lines of business;•motivate executive officers and key employees to achieve strong financial and operational performance;•emphasize performance-based or “at-risk” compensation; and•reward individual performance.Components of Executive CompensationFor the year ended December 31, 2017, the compensation paid to our named executive officers, other than our Chief Executive Officer, consisted of thefollowing components:•annual base salary;•non-equity incentive plan compensation consisting solely of discretionary cash bonuses;•time-vested restricted unit or phantom awards under the equity incentive plan(s);•payment of distribution equivalent rights (“DERs”) on unvested time-based restricted unit or phantom unit awards under the equity incentive plan(s);•vesting of previously issued time-based restricted unit/phantom unit awards issued pursuant to the ETP equity incentive plan(s) or the equity incentiveplan(s) of its affiliates;•401(k) plan employer contributions; and•severance payments where applicable.Mr. Warren, our Chief Executive Officer, has voluntarily elected not to accept any salary, bonus or equity incentive compensation (other than a salary of$1.00 per year plus an amount sufficient to cover his allocated employee premium contributions for health and welfare benefits).MethodologyThe ETP Compensation Committee considers relevant data available to it to assess our competitive position with respect to base salary, annual short-termincentives and long-term incentive compensation for executive officers, including the named executive officers. The ETP Compensation Committee alsoconsiders individual performance, levels of responsibility, skills and experience.Periodically, the compensation committee of the general partner of ETE (the “ETE Compensation Committee”) or the ETP Compensation Committeeengages a third-party consultant to provide market information for compensation levels at peer companies in order to assist in the determination ofcompensation levels for the executives, including the named executive officers. Most recently, Longnecker & Associates (“Longnecker”) evaluated themarket competitiveness of total compensation levels of a number of executives of ETE, ETP and Sunoco Logistics to provide market information with respectto compensation of those executives during the year ended December 31, 2017. In particular, the 2017 review by Longnecker was designed to (i) evaluate themarket competitiveness of total compensation levels for certain members of senior management, including the named executive officers; (ii) assist in thedetermination of appropriate compensation levels for senior management, including the named executive125 Table of Contentsofficers; and (iii) confirm that the compensation programs were yielding compensation packages consistent with the overall compensation philosophy.In conducting its review, Longnecker specifically considered the larger size of the combined ETE and ETP entities from an energy industry perspective.During 2017, Longnecker assisted in the development of the final “peer group” of leading companies in the energy industry that most closely reflect ETP’sprofile in terms of revenues, assets and market value as well as competition for talent at the senior management level and similarly situated general industrycompanies with similar revenues, assets and market value. In setting such peer group, both ETP and Longnecker considered the size of ETE and ETP on acombined basis. Unlike in prior evaluations conducted by Longnecker, a determination was made to focus the analysis specifically on the energy industrybased on a determination that an energy industry peer group provided a more than sufficient amount of comparative data to consider and evaluate totalcompensation. This decision allowed Longnecker to report on specific industry related data comparing the levels of annual base salary, annual short-termcash bonus and long-term equity incentive awards at industry peer group companies with those of the named executive officers to ensure that compensationof the named executive officers is both consistent with the compensation philosophy and competitive with the compensation for executive officers of theseother companies. The identified companies were:Energy Peer Group: • Conoco Phillips • Anadarko Petroleum Corporation• Enterprise Products Partners, L.P. • Marathon Petroleum Corporation• Plains All American Pipeline, L.P. • Kinder Morgan, Inc.• Halliburton Company • The Williams Companies, Inc.• Valero Energy Corporation • Phillips 66The compensation analysis provided by Longnecker in 2017 covered all major components of total compensation, including annual base salary, annualshort-term cash bonus and long-term incentive awards for the senior executives of these companies. In preparing the review materials, Longnecker utilizedgenerally accepted compensation principles as determined by WorldatWork and gathered data from the public peer companies and published salary surveys.Following Longnecker’s 2017 review, both the ETE Compensation Committee and the ETP Compensation Committee reviewed the information provided,including Longnecker’s specific conclusions and recommended considerations for all compensation going forward. The ETE Compensation Committee andETP Compensation Committee considered and reviewed the results of the study performed by Longnecker to determine if the results indicated that thecompensation programs were yielding a competitive total compensation model prioritizing incentive-based compensation and rewarding achievement ofshort and long-term performance objectives and considered Longnecker’s conclusions and recommendations. While Longnecker found that ETP is achievingits stated objectives with respect to the “at-risk” approach, they also found that certain adjustments should be implemented to allow ETP to achieve itstargeted percentiles on base compensation and incentive compensation (short and long-term) as described below.With the pending Sunoco Logistics Merger, the Sunoco Logistics Compensation Committee’s only compensation actions during 2017 prior to closingrelated to 2016 bonus awards and are not reported on in this report on executive compensation.Base Salary. Base salary is designed to provide for a competitive fixed level of pay that attracts and retains executive officers, and compensates them fortheir level of responsibility and sustained individual performance (including experience, scope of responsibility and results achieved). The salaries of thenamed executive officers are reviewed on an annual basis. As discussed above, the base salaries of the named executive officers are targeted to yield anannual base salary slightly below the median level of market (i.e. approximately the 40th percentile of market) and are determined by the ETP CompensationCommittee after taking into account the recommendations of Mr. Warren. During the 2017 merit review process, the ETP Compensation Committeeconsidered the recommendations of Mr. Warren, the results of the Longnecker study and the merit increase pool set for all employees of ETP LLC, ETP andSunoco Logistics.The ETP Compensation Committee approved an increase to Mr. Ramsey’s base salary of 2.5% to $653,438 from its prior level of $637,500, Mr. Wrights basesalary was initially increased 2.5% to $392,063 at the time of merit increases, but was subsequently increased to $415,000 based largely upon the results ofthe Longnecker study. The CEO (who has voluntarily elected to forgo nearly all base compensation) did not receive any base salary adjustment during 2017.In the case of Mr. McCrea, the ETE Compensation Committee approved an increase of 2.5% to Mr. McCrea’s base salary to $1,045,500 from its prior level of$1,020,000.126 Table of ContentsIn the case of Mr. Long, the ETE Compensation Committee approved an increase to Mr. Long’s base salary to $530,000 from its prior level of $459,000,which represents an approximately 15.5% increase and was based largely on the recommendation of Mr. Warren and the results of the Longnecker study.Messrs. Hennigan and Gvazdauskas did not receive a base salary adjustment during 2017, as Mr. Hennigan had left ETP prior to merit increases and Mr.Gvazdauskas had been determined to be a transition employee remaining with ETP only for a short period of time.The 2.5% increase to Mr. Ramsey and the initial 2.5% increase to Mr. Wright reflected a base salary increase consistent with the 2.5% annual merit increasepool established for all employees of the ETP LLC, ETP, Sunoco Logistics and their affiliates for 2017 by the ETP Compensation Committee.Annual Bonus. In addition to base salary, the ETE Compensation Committee and the ETP Compensation Committee make determinations whether to makediscretionary annual cash bonus awards to executives, including the named executive officers, other than the CEO (who has voluntarily elected to forgo anyannual bonuses), following the end of the year under the Energy Transfer Partners, L.L.C. Annual Bonus Plan (the “Bonus Plan”). The ETE CompensationCommittee will consider a 2017 annual cash bonus for Messrs. McCrea and Long and the ETP Compensation Committee will consider 2017 annual cashbonus awards for Messrs. Ramsey and Wright.These discretionary bonuses, if awarded, are intended to reward the named executive officers for the achievement of financial performance objectives duringthe year for which the bonuses are awarded in light of the contribution of each individual to profitability and success during such year. The ETECompensation Committee and the ETP Compensation Committee also consider the recommendation of the CEO in determining the specific annual cashbonus amounts for each of the other named executive officers. The ETE Compensation Committee and the ETP Compensation Committee do not establishtheir own financial performance objectives in advance for purposes of determining whether to approve any annual bonuses, and do not utilize any formulaicapproach to determine annual bonuses.For 2017, annual bonuses to be awarded to Messrs. McCrea, Ramsey, Long, McCrea and Wright will be determined under the Bonus Plan. The ETECompensation Committee’s and the ETP Compensation Committee’s evaluation of performance and determination of an overall available bonus pool isbased on an internal earnings target generally based on targeted EBITDA (the “Earnings Target”) budget and the performance of each department comparedto the applicable departmental budget (with such performance measured based on the specific dollar amount of general and administrative expenses set foreach department). The two performance criteria are weighted 75% on the internal Earnings Target budget criteria and 25% on internal department financialbudget criteria. Internal Earnings Target is the primary performance factor in determining annual bonuses, while internal department financial budget criteriais considered to ensure that general and administrative costs are being effectively managed in a prudent manner.The internal financial budgets are generally developed for each business segment, and then aggregated with appropriate corporate level adjustments, toreflect an overall performance objective that is reasonable in light of market conditions and opportunities based on a high level of effort and dedicationacross all segments of the business. The evaluation of performance versus the internal financial budget is based on EBITDA for a calendar year.In general, both the ETE Compensation Committee and the ETP Compensation Committee believe that performance at or above the internal Earnings Targetand at or below internal department financial budgets would support bonus pools to the named executive officers ranging from 105% to 160% of their annualbase earnings (which amount reflects the actual base salary earned during the calendar year to reflect periods before and after any base salary adjustments),with the ability to fund up to an additional 20% above each named executive officer’s target bonus pool upon achievement of 110% of the internal EarningsTarget and 110% of the internal department financial budgets. For 2017, the short-term annual cash bonus pool targets for each of the named executiveofficers were as follows: for Mr. McCrea, 160% of his annual base earnings; for Mr. Ramsey, 130% of his annual base earnings, which represented anadjustment from his previous target of 140%; for Mr. Long, 130% of his annual base earnings; and for Mr. Wright, 115% of his annual base earnings, whichrepresents an increase from his previous target of 105%. The adjustment to Mr. Ramsey’s base target represented a desire on the part of the Chairman andCEO to align the senior officers that report to him, other than Mr. McCrea, with a consistent bonus target. The increase for Mr. Wright was based onrecognition of his role as General Counsel of ETP and the results of the Longnecker study.In February 2018, the ETP Compensation Committee certified 2017 performance results under the Bonus Plan, which resulted in a bonus payout of 100% oftarget, which reflected achievement of 101.6% of the internal Earnings Target and 100% of the budget criteria. Based on the approved results, the ETPCompensation Committee approved a cash bonus relating to the 2017 calendar year to Messrs. Ramsey and Wright in the amounts of $835,125 and$453,067, respectively.127 Table of ContentsThe ETE Compensation Committee approved a cash bonus relating to the 2017 calendar year to Messrs. McCrea and Long in the amounts of $1,644,554 and$625,100, respectively.In the case of Mr. Hennigan, he received no bonus award in respect of 2017 as he had left ETP prior to consideration of bonus awards. Mr. Gvazdauskas willreceive a cash bonus of $336,000, which amount reflects a target payout at his bonus pool target of 105%. The bonus paid to Mr. Gvazdauskas was approvedoutside of the process of the named executive officers as he no longer serves as a named executive officers, but was considered consistent with the processused to evaluate bonus awards to other executives of ETP.Equity Awards. In 2017, ETE’S Board of Directors adopted the Amended and Restated Energy Transfer Equity, L.P. Long-Term Incentive Plan (the “ETEPlan”). The ETE Plan authorizes the ETE Compensation Committee, in its discretion, to grant awards of restricted units, phantom units, unit options, unitappreciation rights and other awards related to ETE common units upon such terms and conditions as it may determine appropriate and in accordance withgeneral guidelines as defined by the ETE Plan. The ETE Plan has not been approved by a majority of ETE unitholders.ETP currently has three incentive plans: (i) the Second Amended and Restated Energy Transfer Partners, L.P. 2008 Incentive Plan (the “2008 IncentivePlan”); (ii) the Energy Transfer Partners, L.P. Amended and Restated 2011 Long-Term Incentive Plan (the “2011 Incentive Plan”) and the (iii) Energy TransferPartners, L.L.C. Long-Term Incentive Plan, as amended and restated (the “ETP Plan”). Each of the 2008 Incentive Plan, 2011 Incentive Plan and the ETP Planauthorizes the ETP Compensation Committee, in its discretion, to grant awards of restricted units, phantom units, unit options and other awards related toETP common units upon such terms and conditions as it may determine appropriate and in accordance with general guidelines as defined by each such plan.The ETP Compensation Committee determined and/or approved the terms of the unit grants awarded to the named executive officers, including the numberof common units subject to the restricted unit award and the vesting structure of those restricted unit awards. All of the awards granted to the named executiveofficers under these equity incentive plans have consisted of restricted unit awards that are subject to vesting over a specified time period. Upon vesting ofany restricted unit award, ETP common units are issued.Prior to the Sunoco Logistics Merger, Messrs. Hennigan and Gvazdauskas participated in the Sunoco Partners LLC Long-Term Incentive Plan, as amended,(the “Sunoco Logistics Plan”), which became the ETP Plan after the Sunoco Logistics Merger.For 2017, the annual long-term incentive targets for the named executive officers were 900% of annual base salary for Mr. McCrea, 600% of annual basesalary for Mr. Ramsey, 500% of annual base salary for Mr. Long, 300% of annual base salary for Mr. Wright which represented an increase from his priortarget of 250%. Messrs. Hennigan and Gvazdauskas did not receive long-term incentive awards in 2017. The ETP Compensation Committee approved theincrease to Mr. Wright’s long-term incentive target in recognition of his work as General Counsel of ETP and the results of the Longnecker study. Inapproving long-term incentive awards for Mr. Long, the ETP Compensation Committee and the compensation committee of Sunoco LP’s general partnerutilized the targets set by the ETE Compensation Committee.In December 2017, the ETE Compensation Committee in consultation with ETE’s Chairman determined to issue long-term incentive awards under the ETEPlan to the ETE named executive officers, including Messrs. McCrea and Long and Mr. Ramsey. This determination was made in consideration of limitingthe number of units issued under the ETP unit plans for 2017. In December of 2017, the ETE Compensation Committee approved grants of phantom unitawards to Messrs. McCrea, Ramsey and Long of 537,379 units, 223,908 units and 121,074 units, respectively. Messrs. McCrea’s and Ramsey’s 2017 long-term incentive awards were allocated entirely to the ETE Plan.The phantom unit awards provide for vesting over a five-year period, with 60% vesting at the end of the third year and the remaining 40% vesting at the endof the fifth year, generally subject to continued employment through each specified vesting date. The phantom unit awards entitle the recipients of thephantom unit awards to receive, with respect to each ETE unit subject to such award that has not either vested or been forfeited, a DER cash paymentpromptly following each such distribution by ETE to its unitholders. In approving the grant of such restricted unit awards, the ETE Compensation Committeeconsidered several factors, including the long-term objective of retaining such individuals as key drivers of ETE’s and ETP’s future success, the existing levelof equity ownership of such individuals and the previous awards to such individuals of equity awards subject to vesting. Vesting of the 2017 awards wouldaccelerate in the event of the death or disability of the named executive officer or in the event of a change in control of ETE as that term is defined under theETE Plan.Upon vesting of the phantom units awarded under the ETE Plan, the ETE Compensation Committee reserves the right to determine if, upon vesting, suchPhantom units shall be settled in (i) common units of ETE (subject to the approval of the ETE Plan prior to the first vesting date by a majority of ETE’sunitholders pursuant to the rules of the New York Stock Exchange); (ii) cash equal to the Fair Market Value (as such term is defined in the ETE Plan) of theETE common units that would otherwise be delivered pursuant to the terms of each named executive officers grant agreement; or (iii) other securities orproperty (including, without limitation, delivery of common units of ETP purchased by ETE in the open market) in an amount equal to the Fair Market Value128 Table of Contentsof ETE common units that would otherwise be delivered pursuant to the terms of the grant agreement, or a combination thereof as determined by the ETECompensation Committee in its discretionAdditionally, with respect to Mr. Long, in 2017, in discussions between the ETE Compensation Committee and the compensation committees of the generalpartner of Sunoco LP, it was determined that a portion of Mr. Long’s total long-term incentive award target value would be composed of phantom unitsawarded under the ETE Plan as well as restricted phantom units under the Sunoco LP equity plan in consideration for his role and responsibilities at thosepartnerships. Mr. Long’s total 2017 long-term awards were allocated 80% to the ETE Plan and 20% to the Sunoco LP equity plan. Mr. Long serves as afinancial advisor in matters related to mergers and acquisitions and financing activities to Sunoco LP, and certain personnel responsible for the accountingand financial reporting functions provided to Sunoco LP report into his organization.In connection with his role at Sunoco LP, in December 2017, the compensation committee of Sunoco LP’s general partner awarded Mr. Long time-basedrestricted phantom units of Sunoco LP in the amount of 17,097 units. The terms and conditions of the restricted unit/restricted phantom unit awards to Mr.Long under the Sunoco LP equity plan are identical to the terms and conditions of the restricted unit awards under ETP’s equity plans and the phantom unitsawarded under the ETE Plan to other named executive officers.In December 2017, the ETP Compensation Committee approved grants of restricted unit awards to Mr. Wright of 62,250 units under the 2008 Incentive Planrelated to ETP common units.The restricted unit awards under the 2008 Incentive Plan, the 2011 Incentive Plan and the ETP Plan provide for vesting over a five-year period, with 60%vesting at the end of the third year and the remaining 40% vesting at the end of the fifth year, generally subject to continued employment through eachspecified vesting date. The restricted unit awards entitle the recipients of the restricted unit awards to receive, with respect to each ETP common unit subjectto such award that has not either vested or been forfeited, a DER cash payment promptly following each such distribution by ETP to its unitholders. Inapproving the grant of such restricted unit awards, the ETP Compensation Committee considered several factors, including the long-term objective ofretaining such individuals as key drivers of ETP’s future success, the existing level of equity ownership of such individuals and the previous awards to suchindividuals of equity awards subject to vesting. Vesting of the 2014, 2015, 2016 and 2017 awards would accelerate in the event of the death or disability ofthe named executive officer or in the event of a change in control of ETP as that term is defined under the 2008 Incentive Plan and 2011 Incentive Plan. Forawards previously granted under the 2008 Incentive Plan and 2011 Incentive Plan prior to December 2014, unvested awards may also become vested upon achange in control at the discretion of the ETP Compensation Committee. Under the ETP Plan, awards granted in 2014 and 2015 would be accelerated in theevent of a change in control of the applicable partnership (other than a change in control of an affiliate).The restricted phantom unit awards for 2016 and 2017 under the Sunoco LP equity incentive plan generally require the continued employment of therecipient during the vesting period, provided however, the unvested awards will be accelerated in the event of a change in control of the applicablepartnership (other than a change in control to an affiliate) or the death or disability of the award recipient prior to the applicable vesting period beingsatisfied. Under the Sunoco LP equity incentive plan, awards granted in 2014 and 2015 would be accelerated in the event of a change in control of theapplicable partnership (other than a change in control of an affiliate).Messrs. Hennigan and Gvazdauskas did not receive a long-term incentive awards for 2017 as Mr. Hennigan had left ETP prior to merit increases and Mr.Gvazdauskas had been determined to be a transition employee remaining with ETP only for a short period of time.As discussed below under “Potential Payments Upon a Termination or Change of Control,” certain equity awards automatically accelerate upon a change incontrol event, which means vesting automatically accelerates upon a change in control irrespective of whether the officer is terminated. In addition, the 2015award to Mr. Ramsey in accordance with the terms of his offer letter and the 2014 award to Mr. Hennigan included a provision in the applicable awardagreement for acceleration of unvested restricted unit awards upon a termination of employment without “cause” by the general partner of the applicablepartnership issuing the award. For purposes of the awards the term “cause” shall mean: (i) a conviction (treating a nolo contendere plea as a conviction) of afelony (whether or not any right to appeal has been or may be exercised), (ii) willful refusal without proper cause to perform duties (other than any suchrefusal resulting from incapacity due to physical or mental impairment), (iii) misappropriation, embezzlement or reckless or willful destruction of property ofthe partnership or any of its affiliates, (iv) knowing breach of any statutory or common law duty of loyalty to the partnership or any of its or their affiliates, (v)improper conduct materially prejudicial to the business of the partnership or any of its or their affiliates, (vi) material breach of the provisions of anyagreement regarding confidential information entered into with the partnership or any of its or their affiliates or (vii) the continuing failure or refusal tosatisfactorily perform essential duties to the partnership or any of its or their affiliate. Mr. Hennigan’s 2014 award became fully vested upon his termination ofemployment in 2017.129 Table of ContentsPermitting the accelerated vesting of equity awards upon a change in control creates an important retention tool by enabling employees to realize value fromthese awards in the event of a change in control transaction.Unit Ownership Guidelines. In December 2013, the ETP Board adopted the ETP Executive Unit Ownership Guidelines (the “Guidelines”), which set forthminimum ownership guidelines applicable to certain executives of ETP with respect to ETP common units. The applicable unit ownership guidelines aredenominated as a multiple of base salary, and the amount of common units required to be owned increases with the level of responsibility. Under theseGuidelines, the President and Chief Operating Officer is expected to own common units having a minimum value of five times his base salary, while each ofthe remaining named executive officers (other than the CEO) are expected to own common units having a minimum value of four times their respective basesalary. In addition to the named executive officers, these Guidelines also apply to other covered executives, which executives are expected to own eitherdirectly or indirectly in accordance with the terms of the Guidelines, common units having minimum values ranging from two to four times their respectivebase salary. The Guidelines do not apply to the CEO, who receives a salary of $1.00 per year plus an amount sufficient to cover his allocated payrolldeductions for health and welfare benefits.ETP LLC and the ETP Compensation Committee believe that the ownership of the common units, as reflected in the Guidelines, is an important means oftying the financial risks and rewards for the executives to total unitholder return, aligning the interests of such executives with those of ETP’s unitholders,and promoting ETP’s interest in good corporate governance.Covered executives are generally required to achieve their ownership level within five years of becoming subject to the Guidelines. Mr. Ramsey will berequired to be compliant with the Guidelines in November 2020 and Mr. Wright for his current role in 2021.Covered executives may satisfy the Guidelines through direct ownership of common units or indirect ownership by certain immediate family members. Director indirect ownership of ETE and Sunoco LP common units shall count on a one-to-one ratio for purposes of satisfying minimum ownership requirements;however, unvested unit awards may not be used to satisfy the minimum ownership requirements.Covered executives who have not yet met their respective guideline must retain and hold all common units (less common units sold to cover the executive’sapplicable taxes and withholding obligation) received in connection with long-term incentive awards. Once the required ownership level is achieved,ownership of the required common units must be maintained for as long as the covered executive is subject to the Guidelines. However, those individualswho have met or exceeded their applicable ownership guideline may dispose of common units in a manner consistent with applicable laws, rules andregulations, including regulations of the SEC and ETP’s internal policies, but only to the extent that such individual’s remaining ownership of common unitswould continue to exceed the applicable ownership guideline.Qualified Retirement Plan Benefits. The Energy Transfer Partners GP, L.P. 401(k) Plan (the “ETP 401(k) Plan”) is a defined contribution 401(k) plan, whichcovers substantially all of ETP’s employees, including the named executive officers. Employees may elect to defer up to 100% of their eligible compensationafter applicable taxes, as limited under the Code. Matching contributions are not less than the aggregate amount of matching contributions that would becredited to a participant’s account based on a rate of match equal to 100% of each participant’s elective deferrals up to 5% of covered compensation. Theamounts deferred by the participant are fully vested at all times, and the amounts contributed by ETP become vested based on years of service. This benefit isprovided as a means to incentivize employees and provide them with an opportunity to save for their retirement.ETP provides a 3% profit sharing contribution to employee 401(k) accounts for all employees with a base compensation below a specified threshold. Thecontribution is in addition to the 401(k) matching contribution and employees become vested based on years of service.Health and Welfare Benefits. All full-time employees, including the named executive officers, may participate in the health and welfare benefit programsincluding medical, dental, vision, flexible spending, life insurance and disability insurance.Termination Benefits. The named executive officers do not have any employment agreements that call for payments of termination or severance benefits orthat provide for any payments in the event of a change in control of ETP LLC. The 2008 Incentive Plan and 2011 Incentive Plan provide the ETPCompensation Committee with the discretion, unless otherwise specified in the applicable award agreement, to provide for immediate vesting of all unvestedrestricted unit awards in the event of (i) a change of control, as defined in the applicable plan; (ii) death or (iii) disability, as defined in the applicable plan. Inthe case of the December 2014, 2015 and 2016 long-term incentive awards to the named executive officers under the 2008 Incentive Plan or, as applicable,the Sunoco Logistics Plan and the Sunoco LP equity plan, the unvested portion of restricted unit awards would immediately and fully vest in the event of achange of control, as defined in the applicable plan. Please refer to “Compensation Tables - Potential Payments Upon a Termination or Change of Control”for additional information.130 Table of ContentsIn addition, ETP LLC has also adopted the ETP GP Severance Plan and Summary Plan Description effective as of June 12, 2013, (the “Severance Plan”),which provides for payment of certain severance benefits in the event of Qualifying Termination (as that term is defined in the Severance Plan) and related tothe Sunoco Logistics Merger, the Energy Transfer/SXL Merger Severance Plan (the “Severance Plan”). In general, the Severance Plan provides payment oftwo weeks of annual base salary for each year or partial year of employment service, up to a maximum of fifty-two weeks or one year of annual base salary(with a minimum of four weeks of annual base salary) and up to three months of continued group health insurance coverage. The Severance Plan alsoprovides that additional benefits in addition to those provided under the Severance Plan may be paid based on special circumstances, which additionalbenefits shall be unique and non-precedent setting. The Severance Plan is available to all salaried employees on a nondiscriminatory basis; therefore,amounts that would be payable to the named executive officers upon a Qualified Termination have been excluded from “Compensation Tables - PotentialPayments Upon a Termination or Change of Control” below. The SXL Severance Plan, which was adopted in connection with the Sunoco Logistics Merger,provided for an enhanced minimum severance benefit for personnel terminated in connection with the Sunoco Logistics Merger. The SXL Severance Planprovided for two weeks of annual base salary for each year or partial year up to certain maximum levels depending on the employees title. The benefit levelsare summarized below:Employee Level Minimum Severance Pay Maximum Severance PaySenior Manager or below 8 weeks of Base Pay 26 weeks of Base PayDirector or Senior Director 16 weeks of Base Pay 39 weeks of Base PayVice President and above 26 weeks of Base Pay 52 weeks of Base PayThe SXL Severance Plan also provided up to three months of continued group health insurance coverage. In addition, for employees terminated inconnection with the Sunoco Logistics Merger received certain accelerated vesting of awards long-term incentive awards under the 2008 Incentive Plan, the2011 Incentive Plan and the ETP Plan as follows:Employee Level Accelerated Vesting of Outstanding LTIP AwardsSenior Manager or below 30% of the unvested outstanding LTIP awardsDirector or Senior Director 40% of the unvested outstanding LTIP awardsVice President and above 50% of the unvested outstanding LTIP awardsIn 2017, in connection with Mr. Hennigan’s termination of employment, Mr. Hennigan received certain benefits under the SXL Severance Plan, whichprovided Mr. Hennigan with (i) a severance payment of $637,500.00, which is an amount equal to twelve (12) months of Mr. Hennigan’s base salary; and (ii)payment by ETP of the full cost of Mr. Hennigan’s premium for continued health insurance coverage under ETP's health insurance plan for a period of three(3) months. In addition, Mr. Hennigan became entitled to acceleration of the vesting of 262,652 unvested restricted units (the “Accelerated Units”) awardedto Mr. Hennigan pursuant to the terms of the ETP Plan (formerly the Sunoco Partners LLC Long-Term Incentive Plan, as amended and restated). TheAccelerated Units represented consideration of Mr. Hennigan’s non-solicit/non-hire covenant in the Separation Agreement and Full Release of Claimsexecuted by Mr. Hennigan after his termination of employment (the “Hennigan Separation Agreement”). As of his termination date, Mr. Hennigan had a totalof 415,261 unvested restricted units under the ETP Plan and other than the Accelerated Units, the remaining 152,609 were immediately forfeited upon histermination. Mr. Hennigan also received payout of his DC Plan (as that term is defined below) account in the amount of $4,381,604, this payment wasprocessed in January 2018 as payout from the DC Plan to Mr. Hennigan was subject to the deferred payment rule of IRC Section 409(a).In the case of Mr. Gvazdauskas, he became a transition employee as of the closing of the Sunoco Logistics Merger and is expected to remain as such untilsometime during the latter part of the first quarter of 2018. Upon his termination, Mr. Gvazdauskas will be entitled to receive (i) a severance payment of$221,538.46, which is an amount equal to thirty-six (36) weeks of Mr. Gvazdauskas base salary; and (ii) payment by ETP of the full cost of his premium forcontinued health insurance coverage under ETP's health insurance plan for a period of three (3) months. In addition, Mr. Gvazdauskas will become entitled toacceleration of the vesting of 30,180 unvested restricted units (the “Accelerated Units”) awarded to Mr. Gvazdauskas pursuant to the terms of the ETP Plan.The Accelerated Units will represent consideration for his non-solicit/non-hire covenant in the Separation Agreement and Full Release of Claims to beexecuted by Mr. Gvazdauskas after his termination of employment (the “Gvazdauskas Separation Agreement”). As of December 31, 2017, Mr. Gvazdauskashad a total of 60,359 unvested restricted units under the ETP Plan and other than the Accelerated Units, the remaining 30,179 will be immediately forfeitedupon his termination. All payments to Mr. Gvazdauskas will be subject to his execution and non-revocation of the Gvazdauskas Separation Agreement.ETP Deferred Compensation Plan. ETP maintains a deferred compensation plan (“DC Plan”), which permits eligible highly compensated employees to defera portion of their salary and/or bonus until retirement or termination of employment or other131 Table of Contentsdesignated distribution. Under the DC Plan, each year eligible employees are permitted to make an irrevocable election to defer up to 50% of their annualbase salary, 50% of their quarterly non-vested unit distribution income, and/or 50% of their discretionary performance bonus compensation to be earned forservices performed during the following year. Pursuant to the DC Plan, ETP may make annual discretionary matching contributions to participants’ accounts;however, ETP has not made any discretionary contributions to participants’ accounts and currently has no plans to make any discretionary contributions toparticipants’ accounts. All amounts credited under the DC Plan (other than discretionary credits) are immediately 100% vested. Participant accounts arecredited with deemed earnings or losses based on hypothetical investment fund choices made by the participants among available funds.Participants may elect to have their accounts distributed in one lump sum payment or in annual installments over a period of three or five years uponretirement, and in a lump sum upon other termination. Participants may also elect to take lump-sum in-service withdrawals five years or longer in the future,and such scheduled in-service withdrawals may be further deferred prior to the withdrawal date. Upon a change in control (as defined in the DC Plan) of ETP,all DC Plan accounts are immediately vested in full. However, distributions are not accelerated and, instead, are made in accordance with the DC Plan’snormal distribution provisions unless a participant has elected to receive a change of control distribution pursuant to his deferral agreement.ETP Deferred Compensation Plan for Former Sunoco Executives. The ETP Deferred Compensation Plan for Former Sunoco Executives (“Sunoco LogisticsDC Plan”) is a deferred compensation plan established by ETP in connection with ETP’s acquisition of Sunoco Logistics. In 2012, Mr. Hennigan waived anyfuture rights or benefits to which he otherwise would have been entitled under both the Sunoco, Inc. Executive Retirement Plan (“SERP”), a non-qualified,unfunded plan that provided supplemental pension benefits over and above the benefits under the Sunoco, Inc. Retirement Plan (“SCIRP”), a qualifieddefined benefit plan sponsored by Sunoco, Inc., under which benefits are subject to IRS limits for pay and amount, and Sunoco Logistics’ pension restorationplan, in return for which, $2,789,413 of such deferred compensation benefits was credited to Mr. Hennigan’s account under the Sunoco Logistics DC Plan.Mr. Hennigan is the only named executive officer eligible to participate in the Sunoco Logistics DC Plan. Mr. Hennigan’s account is 100 percent vested andwill be distributed in one lump sum payment upon his retirement or termination of employment, or other designated distribution event, including a change ofcontrol (as defined in the Sunoco Logistics DC Plan). His account is credited with deemed earnings (or losses) based on hypothetical investment fund choicesmade by him among available funds. As noted above, Mr. Hennigan received payout of $4,381,604 in connection with his termination. This payment wasprocessed in January 2018 as Mr. Hennigan’s payout from the DC Plan was subject to deferred payment rule of IRC Section 409(a).Risk Assessment Related to Compensation Structure. ETP believes the compensation plans and programs for the named executive officers, as well as otheremployees, are appropriately structured and are not reasonably likely to result in material risk to ETP. ETP believes the compensation plans and programs arestructured in a manner that does not promote excessive risk-taking that could harm value or reward poor judgment. ETP also believes that compensation isallocated among base salary and short and long-term compensation in such a way as to not encourage excessive risk-taking. In particular, ETP generally doesnot adjust base annual salaries for the executive officers and other employees significantly from year to year, and therefore the annual base salary ofemployees is not generally impacted by ETP’s overall financial performance or the financial performance of an operating segment. Whether, and to whatextent, the named executive officers receive a cash bonus is generally determined based on the achievement of specified financial performance objectives aswell as the individual contributions of the named executive officers to ETP’s success. Restricted units or phantom units rather than unit options are used forequity awards because restricted units or phantom units retain value even in a depressed market so that employees are less likely to take unreasonable risks toget, or keep, options “in-the-money.” Finally, the time-based vesting over five years for long-term incentive awards ensures that employees’ interests alignwith those of the unitholders.Tax and Accounting Implications of Equity-Based Compensation ArrangementsDeductibility of Executive CompensationWe are a limited partnership and not a corporation for United States federal income tax purposes. Therefore, we believe that the compensation paid to thenamed executive officers is not subject to the deduction limitations under Section 162(m) of the Internal Revenue Code and therefore is generally fullydeductible for United States federal income tax purposes.Accounting for Unit-Based CompensationFor our unit-based compensation arrangements, including equity-based awards issued to certain of our named executive officers by an affiliate (as discussedabove), we record compensation expense over the vesting period of the awards, as discussed further in Note 9 to our consolidated financial statements.132 Table of ContentsCompensation Committee Interlocks and Insider ParticipationMessrs.

For Messrs. Long, McCrea and Ramsey, amounts include equity awards of our subsidiaries and/or affiliates, as reflected in the “Grants ofPlan-Based Awards Table.” See Note 9 to our consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data” foradditional assumptions underlying the value of the equity awards.(3) During 2017, Mr. Wright had an unrealized loss of $3,245 in his account balance under the DC Plan.(4) The amounts reflected for 2017 in this column include (i) matching contributions to the 401(k) plan made by ETP on behalf of the named executiveofficers of $13,500 for each of Messrs. Long, Ramsey, McCrea and Wright, $12,750 for Mr. Hennigan and $9,846 for Mr. Gvazdauskas, (ii) the dollarvalue of life insurance premiums paid for the benefit of the named executive officers, (iii) $348,173 in severance payments for Mr. Hennigan, and (iv)$5,475,506 to Mr. Hennigan, which represents the value of the accelerated restricted common units under the ETP Plan as consideration for therestrictive covenant contained in the Hennigan Separation Agreement. The amounts reflected for all periods exclude distribution payments inconnection with distribution equivalent rights on unvested unit awards, because the dollar value of such distributions are factored into the grant date fairvalue reported in the “Unit Awards” column of the Summary Compensation Table at the time that the unit awards and distribution equivalent rights wereoriginally granted. For 2017, distribution payments in connection with134 Table of Contentsdistribution equivalent rights totaled $423,809 for Mr. Long, $1,928,181 for Mr. McCrea, $619,224 for Mr. Ramsey, $187,055 for Mr. Wright, $438,100for Mr. Hennigan and $147,237 for Mr. Gvazdauskas.(5) Mr. Warren voluntarily determined that his salary would be reduced to $1.00 per year (plus an amount sufficient to cover his allocated payrolldeductions for health and welfare benefits). He also does not accept a cash bonus or any equity awards under the equity incentive plans.(6) Mr. Ramsey serves as a member of the board of directors of ETE, the owner of our General Partner. Mr. Ramsey’s other compensation for 2015 does notinclude $104,400 of director fees paid in cash by ETE. Mr. Ramsey was also a non-employee director of Sunoco LP during 2015, until his Novemberappointment to our General Partner, and his 2015 other compensation does not include $354,210 of director fees paid in cash by Sunoco LP.(7) The amounts shown for Mr. Hennigan reflect the change in present value for all defined benefit pension plans and supplemental executive retirementplans in which he participated. The applicable disclosure rules require the change in pension value be shown as “$0” if the actual calculation of thechange in pension value is less than zero (i.e., a decrease). The decrease in SCIRP pension value for Mr. Hennigan was $49,762 for 2015. The year-over-year change in actuarial present value of Mr. Hennigan’s pension benefits under the SCIRP for 2015 was negative because Sunoco, Inc. terminated theSCIRP on October 31, 2014. Mr. Hennigan elected to receive his accrued SCIRP benefit in the form of a lump sum. Because the estimate of the presentvalue of his SCIRP benefit at year-end 2014 assumed that Mr. Hennigan (under the Final Average Pay formula) had a 90 percent probability of electing alump sum rather than an annuity (which would be transferred to an insurance company with a premium of 47.5%) at December 1, 2015 as part of the plantermination, the change in actuarial present value from the estimate at year-end 2014 was negative because no such premium was paid, resulting in alower present value of his benefit. Mr. Hennigan did not have any above market preferential payments on deferred compensation during 2017, 2016 or2015.Grants of Plan-Based Awards TableName Grant Date All Other UnitAwards: Number ofUnits(#) All Other OptionAwards: Number ofSecurities UnderlyingOptions(#) Exercise or Base Price ofOption Awards($ / Unit) Grant Date Fair Value ofUnit Awards(1)ETP Unit Awards: Kelcy L.

As discussed in the Compensation Discussion and Analysis above, the restricted unit awards under the 2008 Incentive Plan, the 2011Incentive Plan, as well as, the ETP Plan and the Sunoco LP equity plan, generally require the continued employment of the recipient during the vestingperiod, provided however, unvested awards will be accelerated in the event of the death or disability of the award recipient prior to the applicable vestingperiod being satisfied. In addition, in the event of a change in control, all awards granted in 2014, 2015 and 2016 under the 2008 Incentive Plan or the 2011Incentive Plan, as applicable, and/or the ETP Plan and the Sunoco LP equity plan would be accelerated. For awards granted under the 2008 Incentive Plan orthe ETP Plan and the Sunoco LP equity plan prior to December 2014, unless otherwise specified in the applicable award agreement, unvested awards mayalso become vested upon a change in control at the discretion of the applicable compensation committee. This discussion assumes a scenario in which theETP Compensation Committee, the Sunoco Logistics Compensation Committee137 Table of Contentsor the compensation committee of the general partner of Sunoco LP did not exercise their discretion to accelerate unvested awards in connection with achange in control of the Partnership.The awards under the 2008 Incentive Plan, the 2011 Incentive Plan and the 2014, 2015 and 2016 awards under the ETP Plan (formerly the Sunoco LogisticsPlan) and Sunoco LP equity incentive plan all provide for acceleration of vesting in the event of the death or disability of the award recipient. In addition, theETP Compensation Committee has approved a retirement provision, which provides that employees with at least ten years of service with the general partner,who leave the general partner voluntarily due to retirement, are eligible for accelerated vesting of 40% of his or her award for named executive officers age 65to 68, or 50% of his or her award for named executive officers over age 68. Under the assumption described above, none of the restricted units granted inDecember 2016 would vest upon a named executive officer’s retirement because none of such officers met the age criteria for vesting at such time. For 2015and 2016, the Sunoco Logistics Compensation Committee included a provision in their award agreements which provided that an employee with at least tenyears of service, who leaves employment voluntarily due to retirement, is eligible for accelerated vesting of 40% of his or her award from age 65 to 68 or 50%of his or her award over age 68. The acceleration of the awards is subject to the applicable provisions of IRC Section 409(A).In the event of death, the named executive officers participate in the life insurance plans offered to all employees (i.e., life insurance benefits equal to one andone-half times the named executive officer’s annual base salary, up to a maximum of $750,000 plus any supplemental life insurance elected and paid for bythe named executive officer).In 2017, in connection with Mr. Hennigan’s termination of employment, Mr. Hennigan received certain benefits under the SXL Severance Plan, whichprovided Mr. Hennigan with accelerated of the vesting of 262,652 unvested restricted units (the “Accelerated Units”) awarded to Mr. Hennigan pursuant tothe terms of the ETP Plan. The Accelerated Units represented consideration of Mr. Hennigan’s non-solicit/non-hire covenant in the Separation Agreement andFull Release of Claims executed by Mr. Hennigan after his termination of employment (the “Hennigan Separation Agreement”). As of his termination date,Mr. Hennigan had a total of 415,261 unvested restricted units under the ETP Plan and other than the Accelerated Units, the remaining 170,609 wereimmediately forfeited upon his termination.In the case of Mr. Gvazdauskas, he became a transition employee as of the closing of the Sunoco Logistics Merger and is expected to remain as such until thelatter part of the first quarter 2018. Upon his termination, Mr. Gvazdauskas will be entitled to receive acceleration of the vesting of 30,180 unvested restrictedunits (the “Accelerated Units”) awarded to Mr. Gvazdauskas pursuant to the terms of the ETP Plan. The Accelerated Units will represent consideration for hisnon-solicit/non-hire covenant in the Separation Agreement and Full Release of Claims to be executed by Mr. Gvazdauskas after his termination ofemployment (the “Gvazdauskas Separation Agreement”). As of December 31, 2017, Mr. Gvazdauskas had a total of 60,359 unvested restricted units under theETP Plan and other than the Accelerated Units, the remaining 30,179 will be immediately forfeited upon his termination.Deferred Compensation Plans. As discussed in the Compensation Discussion and Analysis above, all amounts under the DC Plan and the Sunoco LogisticsPlan (other than discretionary credits) are immediately 100% vested. Upon a change in control (as defined in the DC Plan and/or the Sunoco Logistics DCPlan), distributions from the respective plans would be made in accordance with the normal distribution provisions of the respective plan. A change incontrol is generally defined in the DC Plan and the Sunoco Logistics Plan as any change in control event within the meaning of Treasury Regulation Section1.409A-3(i)(5).As noted above, Mr. Hennigan received payout of $4,381,604 in connection with his termination. This payment was processed in January 2018 as Mr.Hennigan’s payout from the DC Plan was subject to deferred payment rule of IRC Section 409(a).CEO Pay RatioIn accordance with Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, set forth below isinformation about the relationship of the annual total compensation of Mr. Warren, ETP’s Chairman and Chief Executive Officer and the annual totalcompensation of our employees.For the 2017 calendar year:The annual total compensation of Mr. Warren, as reported in the Summary Compensation Tables of this Item 11was $5,926; andThe median total compensation of the employees supporting ETP (other than Mr. Warren) was $115,226.Based on this information, for 2017 the ration of the annual total compensation of Mr. Warren to the median of the annual total compensation of the 8,494employees supporting ETP as of December 31, 2017 was approximately 1 to 19 as Mr. Warren has voluntarily elected not to accept any salary, bonus orequity incentive compensation (other than a salary of $1.00 per year plus an amount sufficient to cover his allocated employee premium contributions forhealth and welfare benefits).To identify the median of the annual total compensation of the employees supporting ETP, the following steps were taken:138 Table of Contents1.It was determined that, as of December 31, 2017, the applicable employee populations consisted of 8,494 with all of the identified individuals beingemployed in the United States. This population consisted of all of our full-time and part-time employees. We did not engage any independentcontractors in 2017 that are required to be included in our employee population for the CEO pay ratio evaluation.2.To identify the “median employee” from our employee population, we compared the total earnings of our employees as reflected in our payroll recordsas reported on Form W-2 for 2017.3.We identified our median employee using W-2 reporting and applied this compensation measure consistently to all of our employees required to beincluded in the calculation. We did not make any cost of living adjustments in identifying the “median employee”.4.Once we identified our median employee, we combined all elements of the employee’s compensation for 2017 resulting in an annual compensation of$115,226. The difference between such employee’s total earnings and the employee’s total compensation represents the estimated value of theemployee’s health care benefits (estimated for the employee and such employee’s eligible dependents at $10,800) and the employee’s 401(k) matchingcontribution and profit sharing contribution (estimated at $5,846 per employee, includes $3,633 per employee on average matching contribution and$2,213 per employee on average profit sharing contribution (employees earning over $175,000 in base are ineligible for profit sharing)).5.With respect to Mr. Warren, we used the amount reported in the “Total” column of our 2017 Summary Compensation Table under this Item 11.Director CompensationThe Compensation Committee periodically reviews and makes recommendations regarding the compensation of the directors of our General Partner. In 2017,non-employee directors each received an annual fee of $50,000 in cash. Additionally, the Chairman of the Audit Committee receives an annual fee of$15,000 and the members of the Audit Committee receive an annual fee of $10,000. The Chairman of the ETP Compensation Committee receives an annualfee of $7,500 and the members of the ETP Compensation Committee receive an annual fee of $5,000. In 2017, members of the Conflicts Committee receivedcash payments on a to-be-determined basis for each Conflicts Committee assignment. Employee directors, including Mr. Warren, do not receive any fees forservice as directors. In addition, the non-employee directors participate in the 2008 Incentive Plan. Each director who is not also (i) a shareholder or a director indirect employee of any parent, or (ii) a direct or indirect employee of ETP LLC, ETP, or a subsidiary, who is elected or appointed to the Board for the firsttime shall automatically receive, on the date of his or her election or appointment, an award of 2,500 unvested ETP Common Units. In 2017, non-employeedirectors received annual grants of restricted Common Units equal to an aggregate of $100,000 divided by the closing price of our Common Units on the dateof grant, which will vest 60% after the third year and the remaining 40% after the fifth year after the grant date.The compensation paid to the non-employee directors of our General Partner in 2017 is reflected in the following table:Name Fees Paid in Cash(1)($) Unit Awards(2)($) All Other Compensation($) Total($)Ted Collins, Jr. $94,010 $100,372 $— $194,382Michael K.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCEFor a discussion of director independence, see Item 10. “Directors, Executive Officers and Corporate Governance.”As a policy matter, the Conflicts Committee generally reviews any proposed related-party transaction that may be material to the Partnership to determinewhether the transaction is fair and reasonable to the Partnership. The Partnership’s board of directors makes the determinations as to whether there exists arelated-party transaction in the normal course of reviewing transactions for approval as the Partnership’s board of directors is advised by its management ofthe parties involved in each material transaction as to which the board of directors’ approval is sought by the Partnership’s management. In addition, thePartnership’s board of directors makes inquiries to independently ascertain whether related parties may have an interest in the proposed transaction. Whilethere are no written policies or procedures for the board of directors to follow in making these determinations, the Partnership’s board makes thosedeterminations in light of its contractually-limited fiduciary duties to the Unitholders. The Partnership Agreement provides that any matter approved by theConflicts Committee will be conclusively deemed to be fair and reasonable to the Partnership, approved by all the partners of the Partnership and not abreach by the General Partner or its Board of Directors of any duties they may owe the Partnership or the Unitholders (see “Risks Related to Conflicts ofInterest” in “Item 1A. Risk Factors” in this annual report).ETE owns directly and indirectly the general partner interest in ETP GP, 100% of the ETP Incentive Distribution Rights and 27.5 million ETP CommonUnits.We have a shared services agreement in which we provide various general and administrative services for ETE. See discussion in Note 14 to our consolidatedfinancial statements.We previously had an operating lease agreement with the former owners of ETG, including Mr. Warren and Mr. Davis. We paid these former owners$5 million in annual operating lease payments during the term of the lease and made a one-time payment of $8.8 million in August 2017 and we retained theequipment when the lease expired at that time. With respect to the related party transaction with ETG, the Conflicts Committee of ETP met numerous timesprior to the consummation of the transaction to discuss the terms of the transaction. The committee made the determination that the sale of ETG to ETP wasfair and reasonable to ETP and that the terms of the operating lease between ETP and the former owners of ETG are fair and reasonable to ETP.We received $6 million, $21 million and $23 million in management fees from ETE for the provision of various general and administrative services for ETE’sbenefit for the years ended December 31, 2017, 2016, and 2015, respectively.On July 27, 2016, the Partnership issued to ETE an aggregate amount of 180 Class J units representing limited partner interests in the Partnership (the “ClassJ Units”). A portion of the additional Class J Units will be issued during each of 2016, 2017 and 2018. Each Class J Unit is entitled to an allocation of $10.0million of depreciation, amortization, depletion or other form of cost-recovery during the year in which such Class J Unit was issued; no Class J Unit isentitled to any other allocations of depreciation, amortization, depletion or other cost-recovery in any other year, and such units are not entitled to any cashdistributions at any time. In exchange for the issuance of the Class J Units, ETP’s partnership agreement was amended to further reduce incentive142 Table of Contentsdistributions commencing with the quarter ended June 30, 2016 and ending with the quarter ending December 31, 2017, in an aggregate amount of$720 million.In March 2016, ETP contributed to Sunoco LP its remaining 68.42% interest in Sunoco, LLC and 100% interest in the legacy Sunoco, Inc. retail business for$2.23 billion. Sunoco LP paid $2.20 billion in cash, including a working capital adjustment and issued 5.7 million Sunoco LP common units to RetailHoldings, a wholly-owned subsidiary of the Partnership.Class K UnitsOn December 29, 2016, the Partnership issued to certain of its indirect subsidiaries, in exchange for cash contributions and the exchange of outstandingcommon units representing limited partner interests in the Partnership, Class K Units, each of which is entitled to a quarterly cash distribution of $0.67275per Class K Unit prior to ETP making distributions of available cash to any class of units, excluding any cash available distributions or dividends or capitalstock sales proceeds received by ETP from ETP Holdco. If the Partnership is unable to pay the Class K Unit quarterly distribution with respect to any quarter,the accrued and unpaid distributions will accumulate until paid and any accumulated balance will accrue 1.5% per annum until paid.

AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Tabular dollar and unit amounts, except per unit data, are in millions)1.OPERATIONS AND BASIS OF PRESENTATION:Organization. The consolidated financial statements presented herein contain the results of Energy Transfer Partners, L.P. and its subsidiaries (the“Partnership,” “we,” “us,” “our” or “ETP”). The Partnership is managed by our general partner, ETP GP, which is in turn managed by its general partner,ETP LLC. ETE, a publicly traded master limited partnership, owns ETP LLC, the general partner of our General Partner.In April 2017, ETP and Sunoco Logistics completed the previously announced merger transaction in which Sunoco Logistics acquired ETP in a unit-for-unit transaction (the “Sunoco Logistics Merger”). Under the terms of the transaction, ETP unitholders received 1.5 common units of Sunoco Logistics foreach common unit of ETP they owned. Under the terms of the merger agreement, Sunoco Logistics’ general partner was merged with and into ETP GP,with ETP GP surviving as an indirect wholly-owned subsidiary of ETE. In connection with the merger, the ETP Class H units were cancelled. Theoutstanding ETP Class E units, Class G units, Class I units and Class K units at the effective time of the merger were converted into an equal number ofnewly created classes of Sunoco Logistics units, with the same rights, preferences, privileges, duties and obligations as such classes of ETP units hadimmediately prior to the closing of the merger. Additionally, the outstanding Sunoco Logistics common units and Sunoco Logistics Class B units ownedby ETP at the effective time of the merger were cancelled.In connection with the Sunoco Logistics Merger, Energy Transfer Partners, L.P. changed its name from “Energy Transfer Partners, L.P.” to “EnergyTransfer, LP” and Sunoco Logistics Partners L.P. changed its name to “Energy Transfer Partners, L.P.” For purposes of maintaining clarity, the followingreferences are used herein:•References to “ETLP” refer to Energy Transfer, LP subsequent to the close of the merger;•References to “Sunoco Logistics” refer to the entity named Sunoco Logistics Partners L.P. prior to the close of the merger; and•References to “ETP” refer to the consolidated entity named Energy Transfer Partners, L.P. subsequent to the close of the merger.The Sunoco Logistics Merger resulted in Energy Transfer Partners, L.P. being treated as the surviving consolidated entity from an accountingperspective, while Sunoco Logistics (prior to changing its name to “Energy Transfer Partners, L.P.”) was the surviving consolidated entity from a legaland reporting perspective. Therefore, for the pre-merger periods, the consolidated financial statements reflect the consolidated financial statements of thelegal acquiree (i.e., the entity that was named “Energy Transfer Partners, L.P.” prior to the merger and name changes).The Sunoco Logistics Merger was accounted for as an equity transaction. The Sunoco Logistics Merger did not result in any changes to the carryingvalues of assets and liabilities in the consolidated financial statements, and no gain or loss was recognized. For the periods prior to the Sunoco LogisticsMerger, the Sunoco Logistics limited partner interests that were owned by third parties (other than Energy Transfer Partners, L.P. or its consolidatedsubsidiaries) are presented as noncontrolling interest in these consolidated financial statements.The historical common units and net income (loss) per limited partner unit amounts presented in these consolidated financial statements have beenretrospectively adjusted to reflect the 1.5 to one unit-for-unit exchange in connection with the Sunoco Logistics Merger.The Partnership is engaged in the gathering and processing, compression, treating and transportation of natural gas, focusing on providing midstreamservices in some of the most prolific natural gas producing regions in the United States, including the Eagle Ford, Haynesville, Barnett, Fayetteville,Marcellus, Utica, Bone Spring and Avalon shales.The Partnership is engaged in intrastate transportation and storage natural gas operations that own and operate natural gas pipeline systems that areengaged in the business of purchasing, gathering, transporting, processing, and marketing natural gas and NGLs in the states of Texas, Louisiana, NewMexico and West Virginia.The Partnership owns and operates interstate pipelines, either directly or through equity method investments, that transport natural gas to variousmarkets in the United States.F - 11 Table of ContentsThe Partnership owns a controlling interest in Sunoco Logistics Partners Operations L.P., which owns and operates a logistics business, consisting of ageographically diverse portfolio of complementary pipeline, terminalling, and acquisition and marketing assets, which are used to facilitate the purchaseand sale of crude oil, NGLs and refined products.Basis of Presentation. The consolidated financial statements of the Partnership have been prepared in accordance with GAAP and include the accountsof all controlled subsidiaries after the elimination of all intercompany accounts and transactions. Certain prior year amounts have been conformed to thecurrent year presentation. These reclassifications had no impact on net income or total equity. Management evaluated subsequent events through thedate the financial statements were issued.For prior periods reported herein, certain transactions related to the business of legacy Sunoco Logistics have been reclassified from cost of products soldto operating expenses; these transactions include sales between operating subsidiaries and their marketing affiliates. These reclassifications had noimpact on net income or total equity.The Partnership owns varying undivided interests in certain pipelines. Ownership of these pipelines has been structured as an ownership of an undividedinterest in assets, not as an ownership interest in a partnership, limited liability company, joint venture or other forms of entities. Each owner controlsmarketing and invoices separately, and each owner is responsible for any loss, damage or injury that may occur to their own customers. As a result, theseundivided interests are consolidated proportionately.2.ESTIMATES, SIGNIFICANT ACCOUNTING POLICIES AND BALANCE SHEET DETAIL:Change in Accounting PolicyDuring the fourth quarter of 2017, the Partnership elected to change its method of inventory costing to weighted-average cost for certain inventory thathad previously been accounted for using the last-in, first-out (“LIFO”) method. The inventory impacted by this change included the crude oil, refinedproducts and NGLs associated with the legacy Sunoco Logistics business. Management believes that the weighted-average cost method is preferable tothe LIFO method as it more closely aligns the accounting policies across the consolidated entity, given that the legacy ETP inventory has beenaccounted for using the weighted-average cost method.F - 12 Table of ContentsAs a result of this change in accounting policy, prior periods have been retrospectively adjusted, as follows: Year Ended December 31, 2016 Year Ended December 31, 2015 As OriginallyReported* Effect of Change As Adjusted As OriginallyReported* Effect of Change As AdjustedConsolidated Statement of Operations andComprehensive Income: Cost of products sold$15,039 $41 $15,080 $26,682 $32 $26,714Operating income1,802 (41) 1,761 2,259 (32) 2,227Income before income tax benefit438 (41) 397 1,398 (32) 1,366Net income624 (41) 583 1,521 (32) 1,489Net income attributable to partners297 (9) 288 1,398 (9) 1,389Net loss per common unit - basic(1.37) (0.01) (1.38) (0.06) (0.01) (0.07)Net loss per common unit - diluted(1.37) (0.01) (1.38) (0.07) (0.01) (0.08)Comprehensive income628 (41) 587 1,581 (32) 1,549Comprehensive income attributable to partners301 (9) 292 1,458 (9) 1,449 Consolidated Statements of Cash Flows: Net income624 (41) 583 1,521 (32) 1,489Inventory valuation adjustments(170) 170 — 104 (162) (58)Net change in operating assets and liabilities(change in inventories)(117) (129) (246) (1,367) 194 (1,173) Consolidated Balance Sheets (at periodend): Inventories1,712 (86) 1,626 1,213 (45) 1,168Total partners' capital18,642 (21) 18,621 20,836 (12) 20,824* Amounts reflect certain reclassifications made to conform to the current year presentation.Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reportedamounts of assets and liabilities and the accrual for and disclosure of contingent assets and liabilities at the date of the financial statements and thereported amounts of revenues and expenses during the reporting period.The natural gas industry conducts its business by processing actual transactions at the end of the month following the month of delivery. Consequently,the most current month’s financial results for the midstream, NGL and intrastate transportation and storage operations are estimated using volumeestimates and market prices. Any differences between estimated results and actual results are recognized in the following month’s financial statements.Management believes that the estimated operating results represent the actual results in all material respects.Some of the other significant estimates made by management include, but are not limited to, the timing of certain forecasted transactions that are hedged,the fair value of derivative instruments, useful lives for depreciation and amortization, purchase accounting allocations and subsequent realizability ofintangible assets, fair value measurements used in the goodwill impairment test, market value of inventory, assets and liabilities resulting from theregulated ratemaking process, contingency reserves and environmental reserves. Actual results could differ from those estimates.Recent Accounting PronouncementsASU 2014-09In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts withCustomers (Topic 606) (“ASU 2014-09”), which clarifies the principles for recognizing revenue based on the core principle that an entity shouldrecognize revenue to depict the transfer of promised goods or services toF - 13 Table of Contentscustomers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Partnershipadopted ASU 2014-09 on January 1, 2018. The Partnership applied the cumulative catchup transition method and recognized the cumulative effect ofthe retrospective application of the standard. The effect of the retrospective application of the standard was not material.For future periods, we expect that the adoption of this standard will result in a change to revenues with offsetting changes to costs associated primarilywith the designation of certain of our midstream segment agreements to be in-substance supply agreements, requiring amounts that had previously beenreported as revenue under these agreements to be reclassified to a reduction of cost of sales. Changes to revenues along with offsetting changes to costswill also occur due to changes in the accounting for noncash consideration in multiple of our reportable segments, as well as fuel usage and lossallowances. None of these changes is expected to have a material impact on net income.ASU 2016-02In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which establishes the principlesthat lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flowsarising from a lease. The Partnership expects to adopt ASU 2016-02 in the first quarter of 2019 and is currently evaluating the impact that adopting thisnew standard will have on the consolidated financial statements and related disclosures.ASU 2016-16On January 1, 2018, the Partnership adopted Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-entity Transfers of AssetsOther Than Inventory (“ASU 2016-16”), which requires that entities recognize the income tax consequences of an intra-entity transfer of an asset otherthan inventory when the transfer occurs. The amendments in this update do not change GAAP for the pre-tax effects of an intra-entity asset transfer underTopic 810, Consolidation, or for an intra-entity transfer of inventory. We do not anticipate a material impact to our financial position or results ofoperations as a result of the adoption of this standard.ASU 2017-04In January 2017, the FASB issued ASU No. 2017-04 “Intangibles-Goodwill and other (Topic 350): Simplifying the test for goodwill impairment.” Theamendments in this update remove the second step of the two-step test currently required by Topic 350. An entity will apply a one-step quantitative testand record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount ofgoodwill allocated to the reporting unit. The new guidance did not amend the optional qualitative assessment of goodwill impairment. The standardrequires prospective application and therefore will only impact periods subsequent to the adoption. The Partnership adopted this ASU for its annualgoodwill impairment test in the fourth quarter of 2017.ASU 2017-12In August 2017, the FASB issued ASU No. 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for HedgingActivities.” The amendments in this update improve the financial reporting of hedging relationships to better portray the economic results of an entity’srisk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify theapplication of the hedge accounting guidance in current GAAP. This ASU is effective for financial statements issued for fiscal years, and interim periodswithin those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Partnership is currently evaluating the impact thatadopting this new standard will have on the consolidated financial statements and related disclosures.Revenue RecognitionRevenues for sales of natural gas and NGLs are recognized at the later of the time of delivery of the product to the customer or the time of sale. Revenuesfrom service labor, transportation, treating, compression and gas processing are recognized upon completion of the service. Transportation capacitypayments are recognized when earned in the period the capacity is made available.Our intrastate transportation and storage and interstate transportation and storage segments’ results are determined primarily by the amount of capacityour customers reserve as well as the actual volume of natural gas that flows through the transportation pipelines. Under transportation contracts, ourcustomers are charged (i) a demand fee, which is a fixed fee for the reservation of an agreed amount of capacity on the transportation pipeline for aspecified period of time and which obligates the customer to pay even if the customer does not transport natural gas on the respective pipeline, (ii) atransportation fee, which is based on the actual throughput of natural gas by the customer, (iii) fuel retention based on a percentage of gas transported ontheF - 14 Table of Contentspipeline, or (iv) a combination of the three, generally payable monthly. Fuel retained for a fee is typically valued at market prices.Our intrastate transportation and storage segment also generates revenues and margin from the sale of natural gas to electric utilities, independent powerplants, local distribution companies, industrial end-users and other marketing companies on the HPL System. Generally, we purchase natural gas from themarket, including purchases from our marketing operations, and from producers at the wellhead.In addition, our intrastate transportation and storage segment generates revenues and margin from fees charged for storing customers’ working natural gasin our storage facilities. We also engage in natural gas storage transactions in which we seek to find and profit from pricing differences that occur overtime utilizing the Bammel storage reservoir. We purchase physical natural gas and then sell financial contracts at a price sufficient to cover our carryingcosts and provide for a gross profit margin. We expect margins from natural gas storage transactions to be higher during the periods from November toMarch of each year and lower during the period from April through October of each year due to the increased demand for natural gas during colderweather. However, we cannot assure that management’s expectations will be fully realized in the future and in what time period, due to various factorsincluding weather, availability of natural gas in regions in which we operate, competitive factors in the energy industry, and other issues.Results from the midstream segment are determined primarily by the volumes of natural gas gathered, compressed, treated, processed, purchased and soldthrough our pipeline and gathering systems and the level of natural gas and NGL prices. We generate midstream revenues and segment marginsprincipally under fee-based or other arrangements in which we receive a fee for natural gas gathering, compressing, treating or processing services. Therevenue earned from these arrangements is directly related to the volume of natural gas that flows through our systems and is not directly dependent oncommodity prices.We also utilize other types of arrangements in our midstream segment, including (i) discount-to-index price arrangements, which involve purchases ofnatural gas at either (1) a percentage discount to a specified index price, (2) a specified index price less a fixed amount or (3) a percentage discount to aspecified index price less an additional fixed amount, (ii) percentage-of-proceeds arrangements under which we gather and process natural gas on behalfof producers, sell the resulting residue gas and NGL volumes at market prices and remit to producers an agreed upon percentage of the proceeds based onan index price, (iii) keep-whole arrangements where we gather natural gas from the producer, process the natural gas and sell the resulting NGLs to thirdparties at market prices, (iv) purchasing all or a specified percentage of natural gas and/or NGL delivered from producers and treating or processing ourplant facilities, and (v) making other direct purchases of natural gas and/or NGL at specified delivery points to meet operational or marketingobligations. In many cases, we provide services under contracts that contain a combination of more than one of the arrangements described above. Theterms of our contracts vary based on gas quality conditions, the competitive environment at the time the contracts are signed and customer requirements.Our contract mix may change as a result of changes in producer preferences, expansion in regions where some types of contracts are more common andother market factors.NGL storage and pipeline transportation revenues are recognized when services are performed or products are delivered, respectively. Fractionation andprocessing revenues are recognized when product is either loaded into a truck or injected into a third-party pipeline, which is when title and risk of losspass to the customer.In our natural gas compression business, revenue is recognized for compressor packages and technical service jobs using the completed contract methodwhich recognizes revenue upon completion of the job. Costs incurred on a job are deducted at the time revenue is recognized.We conduct marketing activities in which we market the natural gas that flows through our assets, referred to as on-system gas. We also attract othercustomers by marketing volumes of natural gas that do not move through our assets, referred to as off-system gas. For both on-system and off-system gas,we purchase natural gas from natural gas producers and other supply points and sell that natural gas to utilities, industrial consumers, other marketers andpipeline companies, thereby generating gross margins based upon the difference between the purchase and resale prices.Terminalling and storage revenues are recognized at the time the services are provided. Pipeline revenues are recognized upon delivery of the barrels tothe location designated by the shipper. Crude oil acquisition and marketing revenues, as well as refined product marketing revenues, are recognizedwhen title to the product is transferred to the customer. Revenues are not recognized for crude oil exchange transactions, which are entered into primarilyto acquire crude oil of a desired quality or to reduce transportation costs by taking delivery closer to end markets. Any net differential for exchangetransactions is recorded as an adjustment of inventory costs in the purchases component of cost of products sold and operating expenses in thestatements of operations.F - 15 Table of ContentsRegulatory Accounting – Regulatory Assets and LiabilitiesOur interstate transportation and storage segment is subject to regulation by certain state and federal authorities, and certain subsidiaries in that segmenthave accounting policies that conform to the accounting requirements and ratemaking practices of the regulatory authorities. The application of theseaccounting policies allows certain of our regulated entities to defer expenses and revenues on the balance sheet as regulatory assets and liabilities whenit is probable that those expenses and revenues will be allowed in the ratemaking process in a period different from the period in which they would havebeen reflected in the consolidated statement of operations by an unregulated company. These deferred assets and liabilities will be reported in results ofoperations in the period in which the same amounts are included in rates and recovered from or refunded to customers. Management’s assessment of theprobability of recovery or pass through of regulatory assets and liabilities will require judgment and interpretation of laws and regulatory commissionorders. If, for any reason, we cease to meet the criteria for application of regulatory accounting treatment for these entities, the regulatory assets andliabilities related to those portions ceasing to meet such criteria would be eliminated from the consolidated balance sheet for the period in which thediscontinuance of regulatory accounting treatment occurs.Although Panhandle’s natural gas transmission systems and storage operations are subject to the jurisdiction of FERC in accordance with the Natural GasAct of 1938 and Natural Gas Policy Act of 1978, it does not currently apply regulatory accounting policies in accounting for its operations. Panhandledoes not apply regulatory accounting policies primarily due to the level of discounting from tariff rates and its inability to recover specific costs.Cash, Cash Equivalents and Supplemental Cash Flow InformationCash and cash equivalents include all cash on hand, demand deposits, and investments with original maturities of three months or less. We consider cashequivalents to include short-term, highly liquid investments that are readily convertible to known amounts of cash and that are subject to aninsignificant risk of changes in value.We place our cash deposits and temporary cash investments with high credit quality financial institutions. At times, our cash and cash equivalents maybe uninsured or in deposit accounts that exceed the Federal Deposit Insurance Corporation insurance limit.The net change in operating assets and liabilities (net of effects of acquisitions and deconsolidations) included in cash flows from operating activities iscomprised as follows: Years Ended December 31, 2017 2016 2015Accounts receivable$(950) $(919) $819Accounts receivable from related companies67 30 (243)Inventories37 (497) (157)Other current assets39 83 (178)Other non-current assets, net(94) (78) 188Accounts payable758 972 (1,215)Accounts payable to related companies(3) 29 (160)Accrued and other current liabilities(47) 39 (83)Other non-current liabilities24 33 (219)Price risk management assets and liabilities, net9 62 75Net change in operating assets and liabilities, net of effects of acquisitions anddeconsolidations$(160) $(246) $(1,173)F - 16 Table of ContentsNon-cash investing and financing activities and supplemental cash flow information are as follows: Years Ended December 31, 2017 2016 2015NON-CASH INVESTING ACTIVITIES: Accrued capital expenditures$1,059 $822 $896Sunoco LP limited partner interest received in exchange for contribution of theSunoco, Inc. retail business to Sunoco LP— 194 —Net gains from subsidiary common unit transactions— 37 300NON-CASH FINANCING ACTIVITIES: Issuance of Common Units in connection with the PennTex Acquisition$— $307 $—Issuance of Common Units in connection with the Regency Merger— — 9,250Issuance of Class H Units in connection with the Bakken Pipeline Transaction— — 1,946Contribution of assets from noncontrolling interest988 — 34Redemption of Common Units in connection with the Bakken Pipeline Transaction— — 999Redemption of Common Units in connection with the Sunoco LP Exchange— — 52SUPPLEMENTAL CASH FLOW INFORMATION: Cash paid for interest, net of interest capitalized$1,329 $1,411 $1,467Cash paid for (refund of) income taxes50 (229) 71Accounts ReceivableOur operations deal with a variety of counterparties across the energy sector, some of which are investment grade, and most of which are not. Internalcredit ratings and credit limits are assigned to all counterparties and limits are monitored against credit exposure. Letters of credit or prepayments may berequired from those counterparties that are not investment grade depending on the internal credit rating and level of commercial activity with thecounterparty.We have a diverse portfolio of customers; however, because of the midstream and transportation services we provide, many of our customers are engagedin the exploration and production segment. We manage trade credit risk to mitigate credit losses and exposure to uncollectible trade receivables.Prospective and existing customers are reviewed regularly for creditworthiness to manage credit risk within approved tolerances. Customers that do notmeet minimum credit standards are required to provide additional credit support in the form of a letter of credit, prepayment, or other forms of security.We establish an allowance for doubtful accounts on trade receivables based on the expected ultimate recovery of these receivables and considers manyfactors including historical customer collection experience, general and specific economic trends, and known specific issues related to individualcustomers, sectors, and transactions that might impact collectability. Increases in the allowance are recorded as a component of operating expenses;reductions in the allowance are recorded when receivables are subsequently collected or written-off. Past due receivable balances are written-off whenour efforts have been unsuccessful in collecting the amount due.We enter into netting arrangements with counterparties to the extent possible to mitigate credit risk. Transactions are confirmed with the counterpartyand the net amount is settled when due. Amounts outstanding under these netting arrangements are presented on a net basis in the consolidated balancesheets.InventoriesAs discussed under “Change in Accounting Policy” in Note 2, the Partnership changed its accounting policy for certain inventory in the fourth quarter of2017.Inventories consist principally of natural gas held in storage, NGLs and refined products, crude oil and spare parts, all of which are valued at the lower ofcost or net realizable value utilizing the weighted-average cost method.F - 17 Table of ContentsInventories consisted of the following: December 31, 2017 2016Natural gas, NGLs, and refined products$733 $758Crude oil551 651Spare parts and other305 217Total inventories$1,589 $1,626We utilize commodity derivatives to manage price volatility associated with our natural gas inventory. Changes in fair value of designated hedgedinventory are recorded in inventory on our consolidated balance sheets and cost of products sold in our consolidated statements of operations.Other Current AssetsOther current assets consisted of the following: December 31, 2017 2016Deposits paid to vendors$64 $74Prepaid expenses and other146 224Total other current assets$210 $298Property, Plant and EquipmentProperty, plant and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over theestimated useful or FERC mandated lives of the assets, if applicable. Expenditures for maintenance and repairs that do not add capacity or extend theuseful life are expensed as incurred. Expenditures to refurbish assets that either extend the useful lives of the asset or prevent environmentalcontamination are capitalized and depreciated over the remaining useful life of the asset. Additionally, we capitalize certain costs directly related to theconstruction of assets including internal labor costs, interest and engineering costs. Upon disposition or retirement of pipeline components or natural gasplant components, any gain or loss is recorded to accumulated depreciation. When entire pipeline systems, gas plants or other property and equipmentare retired or sold, any gain or loss is included in our consolidated statements of operations.Property, plant and equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assetsmay not be recoverable. If such a review should indicate that the carrying amount of long-lived assets is not recoverable, we reduce the carrying amountof such assets to fair value.In 2017, the Partnership recorded a $127 million fixed asset impairment related to Sea Robin primarily due to a reduction in expected future cash flowsdue to an increase during 2017 in insurance costs related to offshore assets. In 2016, the Partnership recorded a $133 million fixed asset impairmentrelated to the interstate transportation and storage segment primarily due to expected decreases in future cash flows driven by declines in commodityprices as well as a $10 million impairment to property, plant and equipment in the midstream segment. In 2015, the Partnership recorded a $110 millionfixed asset impairment related to the NGL and refined products transportation and services segment primarily due to an expected decrease in future cashflows. No other fixed asset impairments were identified or recorded for our reporting units during the periods presented.Capitalized interest is included for pipeline construction projects, except for certain interstate projects for which an allowance for funds used duringconstruction (“AFUDC”) is accrued. Interest is capitalized based on the current borrowing rate of our revolving credit facility when the related costs areincurred. AFUDC is calculated under guidelines prescribed by the FERC and capitalized as part of the cost of utility plant for interstate projects. Itrepresents the cost of servicing the capital invested in construction work-in-process. AFUDC is segregated into two component parts – borrowed fundsand equity funds.F - 18 Table of ContentsComponents and useful lives of property, plant and equipment were as follows: December 31, 2017 2016Land and improvements$1,706 $676Buildings and improvements (1 to 45 years)1,960 1,617Pipelines and equipment (5 to 83 years)44,050 36,356Natural gas and NGL storage facilities (5 to 46 years)1,681 1,452Bulk storage, equipment and facilities (2 to 83 years)3,036 3,701Vehicles (1 to 25 years)124 217Right of way (20 to 83 years)3,424 3,349Natural resources434 434Other (1 to 40 years)534 484Construction work-in-process10,750 9,934 67,699 58,220Less – Accumulated depreciation and depletion(9,262) (7,303)Property, plant and equipment, net$58,437 $50,917We recognized the following amounts for the periods presented: Years Ended December 31, 2017 2016 2015Depreciation and depletion expense$2,060 $1,793 $1,713Capitalized interest283 199 163Advances to and Investments in Unconsolidated AffiliatesWe own interests in a number of related businesses that are accounted for by the equity method. In general, we use the equity method of accounting foran investment for which we exercise significant influence over, but do not control, the investee’s operating and financial policies. An impairment of aninvestment in an unconsolidated affiliate is recognized when circumstances indicate that a decline in the investment value is other than temporary.Other Non-Current Assets, netOther non-current assets, net are stated at cost less accumulated amortization.

If such a review should indicate that the carrying amount of amortizable intangible assets is not recoverable, we reduce thecarrying amount of such assets to fair value. We review non-amortizable intangible assets for impairment annually, or more frequently if circumstancesdictate.In 2015, we recorded $24 million of intangible asset impairments related to the NGL and refined products transportation and services segment primarilydue to an expected decrease in future cash flows.GoodwillGoodwill is tested for impairment annually or more frequently if circumstances indicate that goodwill might be impaired. The annual impairment test isperformed during the fourth quarter.F - 20 Table of ContentsChanges in the carrying amount of goodwill were as follows: IntrastateTransportationand Storage InterstateTransportation andStorage Midstream NGL and RefinedProductsTransportation andServices Crude OilTransportation andServices All Other TotalBalance, December 31, 2015$10 $912 $718 $772 $912 $2,104 $5,428Reduction due to contributionof legacy Sunoco, Inc. retailbusiness— — — — — (1,289) (1,289)Acquired— — 177 — 251 — 428Impaired— (638) (32) — — — (670)Balance, December 31, 201610 274 863 772 1,163 815 3,897Acquired— — 8 — 4 — 12Impaired— (262) — (79) — (452) (793)Other— — (1) — — — (1)Balance, December 31, 2017$10 $12 $870 $693 $1,167 $363 $3,115Goodwill is recorded at the acquisition date based on a preliminary purchase price allocation and generally may be adjusted when the purchase priceallocation is finalized.During the fourth quarter of 2017, the Partnership performed goodwill impairment tests on our reporting units and recognized goodwill impairments of$262 million in the interstate transportation and storage segment, $79 million in the NGL and refined products transportation and services segment and$452 million in the all other segment primarily due to changes in assumptions related to projected future revenues and cash flows from the dates thegoodwill was originally recorded.During the fourth quarter of 2016, the Partnership performed goodwill impairment tests on our reporting units and recognized goodwill impairments of$638 million the interstate transportation and storage segment and $32 million in the midstream segment primarily due to decreases in projected futurerevenues and cash flows driven by declines in commodity prices and changes in the markets that these assets serve.During the fourth quarter of 2015, the Partnership performed goodwill impairment tests on our reporting units and recognized goodwill impairments of$99 million in the interstate transportation and storage segment and $106 million in the NGL and refined products transportation and services segmentprimarily due to market declines in current and expected future commodity prices in the fourth quarter of 2015.The Partnership determined the fair value of our reporting units using a weighted combination of the discounted cash flow method and the guidelinecompany method. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimatesand assumptions include revenue growth rates, operating margins, weighted average costs of capital and future market conditions, among others. ThePartnership believes the estimates and assumptions used in our impairment assessments are reasonable and based on available market information, butvariations in any of the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment isindicated. Under the discounted cash flow method, the Partnership determined fair value based on estimated future cash flows of each reporting unitincluding estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflect the overall level of inherentrisk of the reporting unit. Cash flow projections are derived from one year budgeted amounts and five year operating forecasts plus an estimate of laterperiod cash flows, all of which are evaluated by management. Subsequent period cash flows are developed for each reporting unit using growth rates thatmanagement believes are reasonably likely to occur. Under the guideline company method, the Partnership determined the estimated fair value of eachof our reporting units by applying valuation multiples of comparable publicly-traded companies to each reporting unit’s projected EBITDA and thenaveraging that estimate with similar historical calculations using a three year average. In addition, the Partnership estimated a reasonable controlpremium representing the incremental value that accrues to the majority owner from the opportunity to dictate the strategic and operational actions ofthe business.Asset Retirement ObligationsWe have determined that we are obligated by contractual or regulatory requirements to remove facilities or perform other remediation upon retirement ofcertain assets. The fair value of any ARO is determined based on estimates and assumptions related to retirement costs, which the Partnership bases onhistorical retirement costs, future inflation rates and credit-adjustedF - 21 Table of Contentsrisk-free interest rates. These fair value assessments are considered to be Level 3 measurements, as they are based on both observable and unobservableinputs. Changes in the liability are recorded for the passage of time (accretion) or for revisions to cash flows originally estimated to settle the ARO.An ARO is required to be recorded when a legal obligation to retire an asset exists and such obligation can be reasonably estimated. We will record anasset retirement obligation in the periods in which management can reasonably estimate the settlement dates.Except for certain amounts discussed below, management was not able to reasonably measure the fair value of asset retirement obligations as ofDecember 31, 2017 and 2016, in most cases because the settlement dates were indeterminable. Although a number of other onshore assets in Panhandle’ssystem are subject to agreements or regulations that give rise to an ARO upon Panhandle’s discontinued use of these assets, AROs were not recordedbecause these assets have an indeterminate removal or abandonment date given the expected continued use of the assets with proper maintenance orreplacement. Sunoco, Inc. has legal asset retirement obligations for several other assets at its previously owned refineries, pipelines and terminals, forwhich it is not possible to estimate when the obligations will be settled. Consequently, the retirement obligations for these assets cannot be measured atthis time. At the end of the useful life of these underlying assets, Sunoco, Inc. is legally or contractually required to abandon in place or remove the asset.We believe we may have additional asset retirement obligations related to its pipeline assets and storage tanks, for which it is not possible to estimatewhether or when the retirement obligations will be settled. Consequently, these retirement obligations cannot be measured at this time.As of December 31, 2017 and 2016, other non-current liabilities in the Partnership’s consolidated balance sheets included AROs of $165 million and$170 million, respectively.Individual component assets have been and will continue to be replaced, but the pipeline and the natural gas gathering and processing systems willcontinue in operation as long as supply and demand for natural gas exists. Based on the widespread use of natural gas in industrial and power generationactivities, management expects supply and demand to exist for the foreseeable future. We have in place a rigorous repair and maintenance program thatkeeps the pipelines and the natural gas gathering and processing systems in good working order. Therefore, although some of the individual assets maybe replaced, the pipelines and the natural gas gathering and processing systems themselves will remain intact indefinitely.Long-lived assets related to AROs aggregated $2 million and $14 million, and were reflected as property, plant and equipment on our balance sheet as ofDecember 31, 2017 and 2016, respectively. In addition, the Partnership had $21 million and $13 million legally restricted funds for the purpose ofsettling AROs that was reflected as other non-current assets as of December 31, 2017 and 2016, respectively.Accrued and Other Current LiabilitiesAccrued and other current liabilities consisted of the following: December 31, 2017 2016Interest payable$443 $440Customer advances and deposits59 56Accrued capital expenditures1,006 749Accrued wages and benefits208 212Taxes payable other than income taxes108 63Exchanges payable154 208Other165 177Total accrued and other current liabilities$2,143 $1,905Deposits or advances are received from our customers as prepayments for natural gas deliveries in the following month. Prepayments and securitydeposits may also be required when customers exceed their credit limits or do not qualify for open credit.F - 22 Table of ContentsRedeemable Noncontrolling InterestsThe noncontrolling interest holders in one of our consolidated subsidiaries has the option to sell its interests to us. In accordance with applicableaccounting guidance, the noncontrolling interest is excluded from total equity and reflected as redeemable interest on ETP’s consolidated balance sheet.Environmental RemediationWe accrue environmental remediation costs for work at identified sites where an assessment has indicated that cleanup costs are probable and reasonablyestimable. Such accruals are undiscounted and are based on currently available information, estimated timing of remedial actions and related inflationassumptions, existing technology and presently enacted laws and regulations. If a range of probable environmental cleanup costs exists for an identifiedsite, the minimum of the range is accrued unless some other point in the range is more likely in which case the most likely amount in the range isaccrued.Fair Value of Financial InstrumentsThe carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate their fair value.Based on the estimated borrowing rates currently available to us and our subsidiaries for loans with similar terms and average maturities, the aggregatefair value and carrying amount of our debt obligations as of December 31, 2017 was $34.28 billion and $33.09 billion, respectively. As of December 31,2016, the aggregate fair value and carrying amount of our debt obligations was $33.85 billion and $32.93 billion, respectively. The fair value of ourconsolidated debt obligations is a Level 2 valuation based on the observable inputs used for similar liabilities.We have commodity derivatives, interest rate derivatives and embedded derivatives in our preferred units that are accounted for as assets and liabilitiesat fair value in our consolidated balance sheets. We determine the fair value of our assets and liabilities subject to fair value measurement by using thehighest possible “level” of inputs. Level 1 inputs are observable quotes in an active market for identical assets and liabilities. We consider the valuationof marketable securities and commodity derivatives transacted through a clearing broker with a published price from the appropriate exchange as a Level1 valuation. Level 2 inputs are inputs observable for similar assets and liabilities. We consider OTC commodity derivatives entered into directly withthird parties as a Level 2 valuation since the values of these derivatives are quoted on an exchange for similar transactions. Additionally, we consider ouroptions transacted through our clearing broker as having Level 2 inputs due to the level of activity of these contracts on the exchange in which theytrade. We consider the valuation of our interest rate derivatives as Level 2 as the primary input, the LIBOR curve, is based on quotes from an activeexchange of Eurodollar futures for the same period as the future interest swap settlements. Level 3 inputs are unobservable. During the year endedDecember 31, 2017, no transfers were made between any levels within the fair value hierarchy.F - 23 Table of ContentsThe following tables summarize the fair value of our financial assets and liabilities measured and recorded at fair value on a recurring basis as ofDecember 31, 2017 and 2016 based on inputs used to derive their fair values: Fair Value Total Fair Value Measurements at December 31,2017 Level 1 Level 2Assets: Commodity derivatives: Natural Gas: Basis Swaps IFERC/NYMEX$11 $11 $—Swing Swaps IFERC13 — 13Fixed Swaps/Futures70 70 —Forward Physical Swaps8 — 8Power: Forwards23 — 23Natural Gas Liquids – Forwards/Swaps193 193 —Crude – Futures2 2 —Total commodity derivatives320 276 44Other non-current assets21 14 7Total assets$341 $290 $51Liabilities: Interest rate derivatives$(219) $— $(219)Commodity derivatives: Natural Gas: Basis Swaps IFERC/NYMEX(24) (24) —Swing Swaps IFERC(15) (1) (14)Fixed Swaps/Futures(57) (57) —Forward Physical Swaps(2) — (2)Power – Forwards(22) — (22)Natural Gas Liquids – Forwards/Swaps(192) (192) —Refined Products – Futures(25) (25) —Crude – Futures(1) (1) —Total commodity derivatives(338) (300) (38)Total liabilities$(557) $(300) $(257)F - 24 Table of Contents Fair Value Total Fair Value Measurements at December 31, 2016 Level 1 Level 2 Level 3Assets: Commodity derivatives: Natural Gas: Basis Swaps IFERC/NYMEX$14 $14 $— $—Swing Swaps IFERC2 — 2 —Fixed Swaps/Futures96 96 — —Forward Physical Swaps1 — 1 —Power: Forwards4 — 4 —Futures1 1 — —Options – Calls1 1 — —Natural Gas Liquids – Forwards/Swaps233 233 — —Refined Products – Futures1 1 — —Crude – Futures9 9 — —Total commodity derivatives362 355 7 —Other non-current assets13 8 5 —Total assets$375 $363 $12 $—Liabilities: Interest rate derivatives$(193) $— $(193) $—Embedded derivatives in the Legacy ETP Preferred Units(1) — — (1)Commodity derivatives: Natural Gas: Basis Swaps IFERC/NYMEX(11) (11) — —Swing Swaps IFERC(3) — (3) —Fixed Swaps/Futures(149) (149) — —Power: Forwards(5) — (5) —Futures(1) (1) — —Natural Gas Liquids – Forwards/Swaps(273) (273) — —Refined Products – Futures(17) (17) — —Crude – Futures(13) (13) — —Total commodity derivatives(472) (464) (8) —Total liabilities$(666) $(464) $(201) $(1)Contributions in Aid of Construction CostsOn certain of our capital projects, third parties are obligated to reimburse us for all or a portion of project expenditures. The majority of sucharrangements are associated with pipeline construction and production well tie-ins. Contributions in aid of construction costs (“CIAC”) are nettedagainst our project costs as they are received, and any CIAC which exceeds our total project costs, is recognized as other income in the period in which itis realized.Shipping and Handling CostsShipping and handling costs are included in cost of products sold, except for shipping and handling costs related to fuel consumed for compression andtreating which are included in operating expenses.F - 25 Table of ContentsCosts and ExpensesCost of products sold include actual cost of fuel sold, adjusted for the effects of our hedging and other commodity derivative activities, and the cost ofappliances, parts and fittings. Operating expenses include all costs incurred to provide products to customers, including compensation for operationspersonnel, insurance costs, vehicle maintenance, advertising costs, purchasing costs and plant operations. Selling, general and administrative expensesinclude all partnership related expenses and compensation for executive, partnership, and administrative personnel.We record the collection of taxes to be remitted to government authorities on a net basis except for our all other segment in which consumer excise taxeson sales of refined products and merchandise are included in both revenues and costs and expenses in the consolidated statements of operations, with noeffect on net income (loss). For the year ended December 31, 2015, excise taxes collected by Sunoco LP were $1.85 billion. The Partnershipdeconsolidated Sunoco LP effective July 1, 2015 and no excise taxes were collected by our consolidated operations subsequent to that date.Issuances of Subsidiary UnitsWe record changes in our ownership interest of our subsidiaries as equity transactions, with no gain or loss recognized in consolidated net income orcomprehensive income. For example, upon our subsidiary’s issuance of common units in a public offering, we record any difference between the amountof consideration received or paid and the amount by which the noncontrolling interest is adjusted as a change in partners’ capital.Income TaxesETP is a publicly traded limited partnership and is not taxable for federal and most state income tax purposes. As a result, our earnings or losses, to theextent not included in a taxable subsidiary, for federal and most state purposes are included in the tax returns of the individual partners. Net earnings forfinancial statement purposes may differ significantly from taxable income reportable to Unitholders as a result of differences between the tax basis andfinancial basis of assets and liabilities, differences between the tax accounting and financial accounting treatment of certain items, and due to allocationrequirements related to taxable income under our Second Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”).As a publicly traded limited partnership, we are subject to a statutory requirement that our “qualifying income” (as defined by the Internal RevenueCode, related Treasury Regulations, and IRS pronouncements) exceed 90% of our total gross income, determined on a calendar year basis. If ourqualifying income does not meet this statutory requirement, ETP would be taxed as a corporation for federal and state income tax purposes. For the yearsended December 31, 2017, 2016, and 2015, our qualifying income met the statutory requirement.The Partnership conducts certain activities through corporate subsidiaries which are subject to federal, state and local income taxes. These corporatesubsidiaries include ETP Holdco, Inland Corporation, Oasis Pipeline Company and until July 31, 2015, Susser Holding Corporation. The Partnership andits corporate subsidiaries account for income taxes under the asset and liability method.Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between thefinancial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured usingenacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets andliabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established whennecessary to reduce deferred tax assets to the amounts more likely than not to be realized.The determination of the provision for income taxes requires significant judgment, use of estimates, and the interpretation and application of complextax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaininguncertain tax positions. The benefits of uncertain tax positions are recorded in our financial statements only after determining a more-likely-than-notprobability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, we reassessthese probabilities and record any changes through the provision for income taxes.Accounting for Derivative Instruments and Hedging ActivitiesFor qualifying hedges, we formally document, designate and assess the effectiveness of transactions that receive hedge accounting treatment and thegains and losses offset related results on the hedged item in the statement of operations. The market prices used to value our financial derivatives andrelated transactions have been determined using independent third-party prices, readily available market information, broker quotes and appropriatevaluation techniques.F - 26 Table of ContentsAt inception of a hedge, we formally document the relationship between the hedging instrument and the hedged item, the risk management objectives,and the methods used for assessing and testing effectiveness and how any ineffectiveness will be measured and recorded. We also assess, both at theinception of the hedge and on a quarterly basis, whether the derivatives that are used in our hedging transactions are highly effective in offsettingchanges in cash flows. If we determine that a derivative is no longer highly effective as a hedge, we discontinue hedge accounting prospectively byincluding changes in the fair value of the derivative in net income for the period.If we designate a commodity hedging relationship as a fair value hedge, we record the changes in fair value of the hedged asset or liability in cost ofproducts sold in our consolidated statements of operations. This amount is offset by the changes in fair value of the related hedging instrument. Anyineffective portion or amount excluded from the assessment of hedge ineffectiveness is also included in the cost of products sold in the consolidatedstatements of operations.Cash flows from derivatives accounted for as cash flow hedges are reported as cash flows from operating activities, in the same category as the cash flowsfrom the items being hedged.If we designate a derivative financial instrument as a cash flow hedge and it qualifies for hedge accounting, the change in the fair value is deferred inAOCI until the underlying hedged transaction occurs. Any ineffective portion of a cash flow hedge’s change in fair value is recognized each period inearnings. Gains and losses deferred in AOCI related to cash flow hedges remain in AOCI until the underlying physical transaction occurs, unless it isprobable that the forecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period oftime thereafter. For financial derivative instruments that do not qualify for hedge accounting, the change in fair value is recorded in cost of products soldin the consolidated statements of operations.We manage a portion of our interest rate exposures by utilizing interest rate swaps and similar instruments. Certain of our interest rate derivatives areaccounted for as either cash flow hedges or fair value hedges. For interest rate derivatives accounted for as either cash flow or fair value hedges, we reportrealized gains and losses and ineffectiveness portions of those hedges in interest expense. For interest rate derivatives not designated as hedges foraccounting purposes, we report realized and unrealized gains and losses on those derivatives in “Gains (losses) on interest rate derivatives” in theconsolidated statements of operations.Unit-Based CompensationFor awards of restricted units, we recognize compensation expense over the vesting period based on the grant-date fair value, which is determined basedon the market price of our Common Units on the grant date. For awards of cash restricted units, we remeasure the fair value of the award at the end of eachreporting period based on the market price of our Common Units as of the reporting date, and the fair value is recorded in other non-current liabilities onour consolidated balance sheets.Pensions and Other Postretirement Benefit PlansThe Partnership recognizes the overfunded or underfunded status of defined benefit pension and other postretirement plans, measured as the differencebetween the fair value of the plan assets and the benefit obligation (the projected benefit obligation for pension plans and the accumulatedpostretirement benefit obligation for other postretirement plans). Each overfunded plan is recognized as an asset and each underfunded plan isrecognized as a liability. Changes in the funded status of the plan are recorded in the year in which the change occurs within AOCI in equity or, forentities applying regulatory accounting, as a regulatory asset or regulatory liability.Allocation of IncomeFor purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall generally be allocatedamong the partners in accordance with their percentage interests.

The Class B Units that ETP will receive will be a new class of partnership interestsof USAC that will have substantially all of the rights and obligations of a USAC Common Unit, except the Class B Units will not participate indistributions made prior to the one year anniversary of the closing date of the CDM Contribution Agreement (such date, the “Class B Conversion Date”)with respect to USAC Common Units. On the Class B Conversion Date, each Class B Unit will automatically convert into one USAC Common Unit. Thetransaction is expected to close in the first half of 2018, subject to customary closing conditions.In connection with the CDM Contribution Agreement, ETP entered into a purchase agreement with ETE, Energy Transfer Partners, L.L.C. (together withETE, the “GP Purchasers”), USAC Holdings and, solely for certain purposes therein, R/C IV USACP Holdings, L.P., pursuant to which, among otherthings, the GP Purchasers will acquire from USAC Holdings (i) all of the outstanding limited liability company interests in USA Compression GP, LLC,the general partner of USAC (“USAC GP”), and (ii) 12,466,912 USAC Common Units for cash consideration equal to $250 million.2017 TransactionsRover Contribution AgreementIn October 2017, ETP completed the previously announced contribution transaction with a fund managed by Blackstone Energy Partners andBlackstone Capital Partners, pursuant to which ETP exchanged a 49.9% interest in the holding company that owns 65% of the Rover pipeline (“RoverHoldco”).

ETP maintains a controlling financial and voting interest in PEP and is the operator of all of the assets.As such, PEP is reflected as a consolidated subsidiary of the Partnership. ExxonMobil’s interest in PEP is reflected as noncontrolling interest in theconsolidated balance sheets.

In connectionwith ETP’s 2014 acquisition of Susser, ETE agreed to provide ETP a $35 million annual IDR subsidy for 10 years, which terminated upon the closing ofETE’s acquisition of Sunoco GP. In connection with the exchange and repurchase, ETE provided ETP a $35 million annual IDR subsidy for two yearsbeginning with the quarter ended September 30, 2015. In connection with this transaction, the Partnership deconsolidated Sunoco LP, includinggoodwill of $1.81 billion and intangible assets of $982 million related to Sunoco LP. At December 31, 2017, the Partnership held 37.8 million SunocoLP common units accounted for under the equity method.

The results of Sunoco LP’s operations have not been presented asdiscontinued operations and Sunoco LP’s assets and liabilities have not been presented as held for sale in the Partnership’s consolidated financialstatements.F - 30 Table of ContentsBakken PipelineIn March 2015, ETE transferred 46.2 million Partnership common units, ETE’s 45% interest in the Bakken Pipeline project, and $879 million in cash tothe Partnership in exchange for 30.8 million newly issued Class H Units of ETP that, when combined with the 50.2 million previously issued Class HUnits, generally entitled ETE to receive 90.05% of the cash distributions and other economic attributes of the general partner interest and IDRs ofSunoco Logistics (the “Bakken Pipeline Transaction”). In connection with this transaction, the Partnership also issued to ETE 100 Class I Units thatprovided distributions to ETE to offset IDR subsidies previously provided to ETP. These IDR subsidies, including the impact from distributions on ClassI Units, were reduced by $55 million in 2015 and $30 million in 2016. The Class H Units were cancelled in connection with the Sunoco LogisticsMerger in April 2017.In October 2015, Sunoco Logistics completed the acquisition of a 40% membership interest (the “Bakken Membership Interest”) in Bakken HoldingsCompany LLC (“Bakken Holdco”).

The IDR subsidy was $80 million for the year ended December 31, 2015 and will total $60 million per year for the following fouryears.The Regency Merger was a combination of entities under common control; therefore, Regency’s assets and liabilities were not adjusted. ThePartnership’s consolidated financial statements have been retrospectively adjusted to reflect consolidation of Regency for all prior periods subsequent toMay 26, 2010 (the date ETE acquired Regency’s general partner). Predecessor equity included on the consolidated financial statements representsRegency’s equity prior to the Regency Merger.ETP has assumed all of the obligations of Regency and Regency Energy Finance Corp., of which ETP was previously a co-obligor or parent guarantor.4.ADVANCES TO AND INVESTMENTS IN UNCONSOLIDATED AFFILIATES:CitrusETP owns CrossCountry, which in turn owns a 50% interest in Citrus. The other 50% interest in Citrus is owned by a subsidiary of KMI. Citrus owns100% of FGT, an approximately 5,360-mile natural gas pipeline system that originates in Texas and delivers natural gas to the Florida peninsula. Ourinvestment in Citrus is reflected in our interstate transportation and storage segment.FEPWe have a 50% interest in FEP which owns an approximately 185-mile natural gas pipeline that originates in Conway County, Arkansas, continueseastward through White County, Arkansas and terminates at an interconnect with Trunkline Gas Company in Panola County, Mississippi. Ourinvestment in FEP is reflected in the interstate transportation and storage segment. The Partnership evaluated its investment in FEP for impairment as ofDecember 31, 2017, based on FASB Accounting Standards Codification 323, Investments - Equity Method and Joint Ventures. The Partnership recordedan impairment of its investment in FEP of $141 million during the year ended December 31, 2017 due to a negative outlook for long-term transportationcontracts as a result of a decrease in production in the Fayetteville basin and a customer re-contracting with a competitor.F - 31 Table of ContentsMEPWe own a 50% interest in MEP, which owns approximately 500 miles of natural gas pipeline that extends from Southeast Oklahoma, across NortheastTexas, Northern Louisiana and Central Mississippi to an interconnect with the Transcontinental natural gas pipeline system in Butler, Alabama.

In connection with the Sunoco Logistics Merger, the previous Sunoco Logistics equitydistribution agreement was terminated.ETP Preferred UnitsIn November 2017, ETP issued 950,000 of its 6.250% Series A Preferred Units at a price of $1,000 per unit, and 550,000 of its 6.625% Series B PreferredUnits at a price of $1,000 per unit.Distributions on the Series A Preferred Units will accrue and be cumulative from and including the date of original issue to, but excluding, February 15,2023, at a rate of 6.250% per annum of the stated liquidation preference of $1,000. On and after February 15, 2023, distributions on the Series A PreferredUnits will accumulate at a percentage of the $1,000 liquidation preference equal to an annual floating rate of the three-month LIBOR, determinedquarterly, plus a spread of 4.028% per annum. The Series A Preferred Units are redeemable at ETP’s option on or after February 15, 2023 at a redemptionprice of $1,000 per Series A Preferred Unit, plus an amount equal to all accumulated and unpaid distributions thereon to, but excluding, the date ofredemption.Distributions on the Series B Preferred Units will accrue and be cumulative from and including the date of original issue to, but excluding, February 15,2028, at a rate of 6.625% per annum of the stated liquidation preference of $1,000. On and after February 15, 2028, distributions on the Series B PreferredUnits will accumulate at a percentage of the $1,000 liquidationF - 42 Table of Contentspreference equal to an annual floating rate of the three-month LIBOR, determined quarterly, plus a spread of 4.155% per annum. The Series B PreferredUnits are redeemable at ETP’s option on or after February 15, 2028 at a redemption price of $1,000 per Series B Preferred Unit, plus an amount equal toall accumulated and unpaid distributions thereon to, but excluding, the date of redemption.PennTex Tender Offer and Limited Call Right ExerciseIn June 2017, ETP purchased all of the outstanding PennTex common units not previously owned by ETP for $20.00 per common unit in cash. ETP nowowns all of the economic interests of PennTex, and PennTex common units are no longer publicly traded or listed on the NASDAQ.Quarterly Distributions of Available CashUnder the Partnership’s limited partnership agreement, within 45 days after the end of each quarter, the Partnership distributes all cash on hand at the endof the quarter, less reserves established by the general partner in its discretion. This is defined as “available cash” in the partnership agreement. Thegeneral partner has broad discretion to establish cash reserves that it determines are necessary or appropriate to properly conduct the Partnership’sbusiness. The Partnership will make quarterly distributions to the extent there is sufficient cash from operations after establishment of cash reserves andpayment of fees and expenses, including payments to the general partner.If cash distributions exceed $0.0833 per unit in a quarter, the holders of the incentive distribution rights receive increasing percentages, up to 48 percent,of the cash distributed in excess of that amount. These distributions are referred to as “incentive distributions.”The following table shows the target distribution levels and distribution “splits” between the general and limited partners and the holders of thePartnership’s incentive distribution rights (”IDRs”): Marginal Percentage Interest inDistributions Total Quarterly Distribution Target Amount IDRs Partners (1)Minimum Quarterly Distribution $0.0750 —% 100%First Target Distribution up to $0.0833 —% 100%Second Target Distribution above $0.0833 up to $0.0958 13% 87%Third Target Distribution above $0.0958 up to $0.2638 35% 65%Thereafter above $0.2638 48% 52%(1) Includes general partner and limited partner interests, based on the proportionate ownership of each. The percentage interests shown for the unitholders and the general partner for the minimum quarterly distribution are also applicable to quarterlydistribution amounts that are less than the minimum quarterly distribution.Distributions on common units declared and paid by ETP and Sunoco Logistics during the pre-merger periods were as follows:Quarter Ended ETP Sunoco LogisticsDecember 31, 2014 $0.6633 $0.4000March 31, 2015 0.6767 0.4190June 30, 2015 0.6900 0.4380September 30, 2015 0.7033 0.4580December 31, 2015 0.7033 0.4790March 31, 2016 0.7033 0.4890June 30, 2016 0.7033 0.5000September 30, 2016 0.7033 0.5100December 31, 2016 0.7033 0.5200F - 43 Table of ContentsDistributions on common units declared and paid by Post-Merger ETP were as follows:Quarter Ended Record Date Payment Date RateMarch 31, 2017 May 10, 2017 May 16, 2017 $0.5350June 30, 2017 August 7, 2017 August 15, 2017 0.5500September 30, 2017 November 7, 2017 November 14, 2017 0.5650December 31, 2017 February 8, 2018 February 14, 2018 0.5650In connection with previous transactions, ETE has agreed to relinquish its right to the following amounts of incentive distributions in future periods: Total Year2018 $1532019 128Each year beyond 2019 33Distributions declared and paid by ETP to the preferred unitholders were as follows: Distribution per Preferred UnitQuarter Ended Record Date Payment Date Series A Series BDecember 31, 2017 February 1, 2018 February 15, 2018 $15.451 $16.378Accumulated Other Comprehensive IncomeThe following table presents the components of AOCI, net of tax: December 31, 2017 2016Available-for-sale securities$8 $2Foreign currency translation adjustment(5) (5)Actuarial gain related to pensions and other postretirement benefits(5) 7Investments in unconsolidated affiliates, net5 4Total AOCI, net of tax$3 $8The table below sets forth the tax amounts included in the respective components of other comprehensive income: December 31, 2017 2016Available-for-sale securities$(2) $(2)Foreign currency translation adjustment3 3Actuarial loss relating to pension and other postretirement benefits3 —Total$4 $19.UNIT-BASED COMPENSATION PLANS:ETP Unit-Based Compensation PlanWe have issued equity incentive plans for employees, officers and directors, which provide for various types of awards, including options to purchaseETP Common Units, restricted units, phantom units, Common Units, distribution equivalent rights (“DERs”), Common Unit appreciation rights, andother unit-based awards. As of December 31, 2017, an aggregate total of 8.4 million ETP Common Units remain available to be awarded under our equityincentive plans.F - 44 Table of ContentsRestricted UnitsWe have granted restricted unit awards to employees that vest over a specified time period, typically a five-year service vesting requirement, with vestingbased on continued employment as of each applicable vesting date. Upon vesting, ETP Common Units are issued. These unit awards entitle therecipients of the unit awards to receive, with respect to each Common Unit subject to such award that has not either vested or been forfeited, a cashpayment equal to each cash distribution per Common Unit made by us on our Common Units promptly following each such distribution by us to ourUnitholders. We refer to these rights as “distribution equivalent rights.” Under our equity incentive plans, our non-employee directors each receivegrants with a five-year service vesting requirement.The following table shows the activity of the awards granted to employees and non-employee directors: Number of Units Weighted Average Grant-DateFair Value Per UnitUnvested awards as of December 31, 20169.4 $27.68Legacy Sunoco Logistics unvested awards as of December 31, 20163.2 28.57Awards granted4.9 17.69Awards vested(2.3) 34.22Awards forfeited(1.1) 25.03Unvested awards as of December 31, 201714.1 23.18During the years ended December 31, 2017, 2016, and 2015, the weighted average grant-date fair value per unit award granted was $17.69, $23.82 and$23.47, respectively. The total fair value of awards vested was $40 million, $40 million and $57 million, respectively, based on the market price of ETPCommon Units as of the vesting date. As of December 31, 2017, a total of 14.1 million unit awards remain unvested, for which ETP expects to recognizea total of $189 million in compensation expense over a weighted average period of 2.7 years.Cash Restricted Units. The Partnership previously granted cash restricted units, which entitled the award recipient to receive cash equal to the marketvalue of one ETP Common Unit upon vesting. The Partnership does not currently have any cash restricted units outstanding.10.INCOME TAXES:As a partnership, we are not subject to United States federal income tax and most state income taxes. However, the Partnership conducts certain activitiesthrough corporate subsidiaries which are subject to federal and state income taxes. The components of the federal and state income tax expense (benefit)are summarized as follows: Years Ended December 31, 2017 2016 2015Current expense (benefit): Federal$53 $18 $(274)State(18) (35) (51)Total35 (17) (325)Deferred expense (benefit): Federal(1,723) (173) 231State192 4 (29)Total(1,531) (169) 202Total income tax benefit$(1,496) $(186) $(123)F - 45 Table of ContentsHistorically, our effective rate has differed from the statutory rate primarily due to Partnership earnings that are not subject to United States federal andmost state income taxes at the partnership level. A reconciliation of income tax expense at the United States statutory rate to the Partnership’s income taxbenefit for the years ended December 31, 2017, 2016 and 2015 is as follows: Years Ended December 31, 2017 2016* 2015*Income tax expense at United States statutory rate of 35 percent$352 $139 $479Increase (reduction) in income taxes resulting from: Partnership earnings not subject to tax(457) (504) (504)Federal rate change(1,559) ——Goodwill impairments172 223 —State income taxes (net of federal income tax effects)131 (17) (37)Dividend received deduction(14) (15) (24)Audit settlement— — (7)Change in tax status of subsidiary(124) — —Other3 (12) (30)Income tax benefit$(1,496) $(186) $(123)* As adjusted.

Our corporate subsidiaries have state net operating losscarryforward benefits of $210 million, net of federal tax, which expire between 2018 and 2036. A valuation allowance of $186 million is applicable tothe state net operating loss carryforward benefits primarily attributable to significant restrictions on their use in the Commonwealth of Pennsylvania andthe remaining $3 million valuation allowance is applicable to the federal net operating loss carryforward benefit.The following table sets forth the changes in unrecognized tax benefits: Years Ended December 31, 2017 2016 2015Balance at beginning of year$615 $610 $440Additions attributable to tax positions taken in the current year— 8 —Additions attributable to tax positions taken in prior years28 18 178Reduction attributable to tax positions taken in prior years(25) (20) —Lapse of statute(9) (1) (8)Balance at end of year$609 $615 $610As of December 31, 2017, we have $605 million ($576 million after federal income tax benefits) related to tax positions which, if recognized, wouldimpact our effective tax rate.Our policy is to accrue interest expense and penalties on income tax underpayments (overpayments) as a component of income tax expense. During2017, we recognized interest and penalties of less than $3 million. At December 31, 2017, we have interest and penalties accrued of $9 million, net oftax.Sunoco, Inc. has historically included certain government incentive payments as taxable income on its federal and state income tax returns. Inconnection with Sunoco, Inc.’s 2004 through 2011 years, Sunoco, Inc. filed amended returns with the IRS excluding these government incentivepayments from federal taxable income. The IRS denied the amended returns, and Sunoco, Inc. petitioned the Court of Federal Claims (“CFC”) in June2015 on this issue. In November 2016, the CFC ruled against Sunoco, Inc., and Sunoco, Inc. is appealing this decision to the Federal Circuit. If Sunoco,Inc. is ultimately fully successful in this litigation, it will receive tax refunds of approximately $530 million. However, due to the uncertaintysurrounding the litigation, a reserve of $530 million was established for the full amount of the litigation. Due to the timing of the litigation and therelated reserve, the receivable and the reserve for this issue have been netted in the financial statements as of December 31, 2017.In December 2015, the Pennsylvania Commonwealth Court determined in Nextel Communications v. Commonwealth (“Nextel”) that the Pennsylvanialimitation on NOL carryforward deductions violated the uniformity clause of the Pennsylvania Constitution and struck the NOL limitation in its entirety. In October 2017, the Pennsylvania Supreme Court affirmed the decision with respect to the uniformity clause violation; however, the Court reversedwith respect to the remedy and instead severed the flat-dollar limitation, leaving the percentage-based limitation intact. Nextel has until April 4, 2018 tofile a petition for writ of certiorari with the U.S. Supreme Court. Sunoco, Inc. has recognized approximately $67 million ($53 million after federalincome tax benefits) in tax benefit based on previously filed tax returns and certain previously filed protective claims as relates to its cases currently heldpending the Nextel matter. However, based upon the Pennsylvania Supreme Court’sF - 47 Table of ContentsOctober 2017 decision, and because of uncertainty in the breadth of the application of the decision, we have reserved $27 million ($21 million afterfederal income tax benefits) against the receivable.In general, ETP and its subsidiaries are no longer subject to examination by the Internal Revenue Service (“IRS”), and most state jurisdictions, for the2013 and prior tax years. However, Sunoco, Inc. and its subsidiaries are no longer subject to examination by the IRS for tax years prior to 2007.Sunoco, Inc. has been examined by the IRS for tax years through 2013. However, statutes remain open for tax years 2007 and forward due to carryback ofnet operating losses and/or claims regarding government incentive payments discussed above. All other issues are resolved. Though we believe the taxyears are closed by statute, tax years 2004 through 2006 are impacted by the carryback of net operating losses and under certain circumstances may beimpacted by adjustments for government incentive payments.ETP and its subsidiaries also have various state and local income tax returns in the process of examination or administrative appeal in variousjurisdictions. We believe the appropriate accruals or unrecognized tax benefits have been recorded for any potential assessment with respect to theseexaminations.On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. Among other provisions, the highest corporate federal income tax rate wasreduced from 35% to 21% for taxable years beginning after December 31, 2017. As a result, the Partnership recognized a deferred tax benefit of $1.56billion in December 2017. For the year ended December 2016, the Partnership recorded an income tax benefit due to pre-tax losses at its corporatesubsidiaries.11.REGULATORY MATTERS, COMMITMENTS, CONTINGENCIES AND ENVIRONMENTAL LIABILITIES:Contingent Residual Support Agreement – AmeriGasIn connection with the closing of the contribution of its propane operations in January 2012, ETP previously provided contingent residual support ofcertain debt obligations of AmeriGas. AmeriGas has subsequently repaid the remainder of the related obligations and ETP no longer provides contingentresidual support for any AmeriGas notes.Guarantee of Sunoco LP NotesIn connection with previous transactions whereby Retail Holdings contributed assets to Sunoco LP, Retail Holdings provided a limited contingentguarantee of collection, but not of payment, to Sunoco LP with respect to (i) $800 million principal amount of 6.375% senior notes due 2023 issued bySunoco LP, (ii) $800 million principal amount of 6.25% senior notes due 2021 issued by Sunoco LP and (iii) $2.035 billion aggregate principal forSunoco LP’s term loan due 2019. In December 2016, Retail Holdings contributed its interests in Sunoco LP, along with the assignment of the guaranteeof Sunoco LP’s senior notes, to its subsidiary, ETC M-A Acquisition LLC (“ETC M-A”).On January 23, 2018, Sunoco LP redeemed the previously guaranteed senior notes and issued the following notes for which ETC M-A has alsoguaranteed collection with respect to the payment of principal amounts:•$1.00 billion aggregate principal amount of 4.875%, senior notes due 2023;•$800 million aggregate principal amount of 5.50% senior notes due 2026; and•$400 million aggregate principal amount of 5.875% senior notes due 2028.Under the guarantee of collection, ETC M-A would have the obligation to pay the principal of each series of notes once all remedies, including in thecontext of bankruptcy proceedings, have first been fully exhausted against Sunoco LP with respect to such payment obligation, and holders of the notesare still owed amounts in respect of the principal of such notes. ETC M-A will not otherwise be subject to the covenants of the indenture governing thenotes.FERC AuditIn March 2016, the FERC commenced an audit of Trunkline for the period from January 1, 2013 to present to evaluate Trunkline’s compliance with therequirements of its FERC gas tariff, the accounting regulations of the Uniform System of Accounts as prescribed by the FERC, and the FERC’s annualreporting requirements. The audit is ongoing.CommitmentsIn the normal course of business, ETP purchases, processes and sells natural gas pursuant to long-term contracts and enters into long-term transportationand storage agreements. Such contracts contain terms that are customary in the industry. ETPF - 48 Table of Contentsbelieves that the terms of these agreements are commercially reasonable and will not have a material adverse effect on its financial position or results ofoperations.ETP’s joint venture agreements require that it funds its proportionate share of capital contributions to its unconsolidated affiliates. Such contributionswill depend upon ETP’s unconsolidated affiliates’ capital requirements, such as for funding capital projects or repayment of long-term obligations.We have certain non-cancelable leases for property and equipment, which require fixed monthly rental payments and expire at various dates through2034.

Natural gas and crude oilare flammable and combustible. Serious personal injury and significant property damage can arise in connection with their transportation, storage or use.In the ordinary course of business, we are sometimes threatened with or named as a defendant in various lawsuits seeking actual and punitive damages forproduct liability, personal injury and property damage. We maintain liability insurance with insurers in amounts and with coverage and deductiblesmanagement believes are reasonable and prudent, and which are generally accepted in the industry. However, there can be no assurance that the levels ofinsurance protection currently in effect will continue to be available at reasonable prices or that such levels will remain adequate to protect us frommaterial expenses related to product liability, personal injury or property damage in the future.Dakota Access PipelineOn July 25, 2016, the United States Army Corps of Engineers (“USACE”) issued permits to Dakota Access consistent with environmental and historicpreservation statutes for the pipeline to make two crossings of the Missouri River in North Dakota, including a crossing of the Missouri River at LakeOahe. After significant delay, the USACE also issued easements to allow the pipeline to cross land owned by the USACE adjacent to the Missouri Riverin two locations. Also in July, the Standing Rock Sioux Tribe (“SRST”) filed a lawsuit in the United States District Court for the District of Columbiaagainst the USACE that challenged the legality of the permits issued for the construction of the Dakota Access pipeline across those waterways andclaimed violations of the National Historic Preservation Act (“NHPA”). The SRST also sought a preliminary injunction to rescind the USACE permitswhile the case is pending. Dakota Access intervened in the case. The SRST soon added aF - 49 Table of Contentsrequest for an emergency temporary restraining order (“TRO”) to stop construction on the pipeline project. On September 9, 2016, the Court deniedSRST’s motion for a preliminary injunction, rendering the TRO request moot.After the September 9, 2016 ruling, the Department of the Army, the DOJ, and the Department of the Interior released a joint statement that the USACEwould not grant the easement for the land adjacent to Lake Oahe until the Department of the Army completed a review to determine whether it wasnecessary to reconsider the USACE’s decision under various federal statutes relevant to the pipeline approval.The SRST appealed the denial of the preliminary injunction to the United States Court of Appeals for the D.C. Circuit and filed an emergency motion inthe United States District Court for an injunction pending the appeal, which was denied. The D.C. Circuit then denied the SRST’s application for aninjunction pending appeal and later dismissed SRST’s appeal of the order denying the preliminary injunction motion. The SRST filed an amendedcomplaint and added claims based on treaties between the tribes and the United States and statutes governing the use of government property.In December 2016, the Department of the Army announced that, although its prior actions complied with the law, it intended to conduct furtherenvironmental review of the crossing at Lake Oahe. In February 2017, in response to a presidential memorandum, the Department of the Army decidedthat no further environmental review was necessary and delivered an easement to Dakota Access allowing the pipeline to cross Lake Oahe. Almostimmediately, the Cheyenne River Sioux Tribe (“CRST”), which had intervened in the lawsuit in August 2016, moved for a preliminary injunction andTRO to block operation of the pipeline. These motions raised, for the first time, claims based on the religious rights of the Tribe. The District Courtdenied the TRO and preliminary injunction, and the CRST appealed and requested an injunction pending appeal in the district court and the D.C.Circuit. Both courts denied the CRST’s request for an injunction pending appeal. Shortly thereafter, at CRST’s request, the D.C. Circuit dismissedCRST’s appeal.The SRST and the CRST amended their complaints to incorporate religious freedom and other claims. In addition, the Oglala and Yankton Sioux tribes(collectively, “Tribes”) have filed related lawsuits to prevent construction of the Dakota Access pipeline project. These lawsuits have been consolidatedinto the action initiated by the SRST. Several individual members of the Tribes have also intervened in the lawsuit asserting claims that overlap withthose brought by the four Tribes.On June 14, 2017, the Court ruled on SRST’s and CRST’s motions for partial summary judgment and the USACE’s cross-motions for partial summaryjudgment. The Court rejected the majority of the Tribes’ assertions and granted summary judgment on most claims in favor of the USACE and DakotaAccess. In particular, the Court concluded that the USACE had not violated any trust duties owed to the Tribes and had generally complied with itsobligations under the Clean Water Act, the Rivers and Harbors Act, the Mineral Leasing Act, the National Environmental Policy Act (“NEPA”) and otherrelated statutes; however, the Court remanded to the USACE three discrete issues for further analysis and explanation of its prior determinations undercertain of these statutes. The Court ordered briefing to determine whether the pipeline should remain in operation during the pendency of the USACE’sreview process or whether to vacate the existing permits. The USACE and Dakota Access opposed any shutdown of operations of the pipeline during thisreview process. On October 11, 2017, the Court issued an order allowing the pipeline to remain in operation during the pendency of the USACE’s reviewprocess. In early October 2017, USACE advised the Court that it expects to complete the additional analysis and explanation of its prior determinationsrequested by the Court by April 2018.On December 4, 2017, the Court imposed three conditions on continued operation of the pipeline during the remand process. First, Dakota Access mustretain an independent auditor to review its compliance with the conditions and regulations governing its easements and to assess integrity threats to thepipeline. The auditor’s report is required to be filed with the Court by April 1, 2018. Second, the Court has directed Dakota Access to continue its workwith the Tribes and the USACE to revise and finalize its emergency spill response planning for the section of the pipeline crossing Lake Oahe. DakotaAccess is required to file the revised plan with the Court by April 1, 2018. And third, the Court has directed Dakota Access to submit bi-monthly reportsduring the remand period disclosing certain inspection and maintenance information related to the segment of the pipeline running between the valveson either side of the Lake Oahe crossing. The first report was filed with the court on December 29, 2017.In November 2017, the Yankton Sioux Tribe (“YST”), moved for partial summary judgment asserting claims similar to those already litigated anddecided by the Court in its June 14, 2017 decision on similar motions by CRST and SRST. YST argues that the USACE and Fish and Wildlife Serviceviolated NEPA, the Mineral Leasing Act, the Rivers and Harbors Act, and YST’s treaty and trust rights when the government granted the permits andeasements necessary for the pipeline. Briefing on YST’s motion is ongoing.While we believe that the pending lawsuits are unlikely to halt or suspend the operation of the pipeline, we cannot assure this outcome. We cannotdetermine when or how these lawsuits will be resolved or the impact they may have on the Dakota Access project.F - 50 Table of ContentsMont Belvieu IncidentOn June 26, 2016, a hydrocarbon storage well located on another operator’s facility adjacent to Lone Star NGL Mont Belvieu’s (“Lone Star”) facilities inMont Belvieu, Texas experienced an over-pressurization resulting in a subsurface release. The subsurface release caused a fire at Lone Star’s SouthTerminal and damage to Lone Star’s storage well operations at its South and North Terminals. Normal operations have resumed at the facilities with theexception of one of Lone Star’s storage wells. Lone Star is still quantifying the extent of its incurred and ongoing damages and has or will be seekingreimbursement for these losses.MTBE LitigationSunoco, Inc. and/or Sunoco, Inc. (R&M), (now known as Sunoco (R&M), LLC) along with other members of the petroleum industry, are defendants inlawsuits alleging MTBE contamination of groundwater. The plaintiffs, state-level governmental entities, assert product liability claims and additionalclaims including nuisance, trespass, negligence, violation of environmental laws, and/or deceptive business practices. The plaintiffs seek to recovercompensatory damages, and in some cases also seek natural resource damages, injunctive relief, punitive damages, and attorneys’ fees.As of December 31, 2017, Sunoco, Inc. is a defendant in seven cases, including one case each initiated by the States of Maryland, New Jersey, Vermont,Rhode Island, one by the Commonwealth of Pennsylvania and two by the Commonwealth of Puerto Rico. The more recent Puerto Rico action is acompanion case alleging damages for additional sites beyond those at issue in the initial Puerto Rico action. The actions brought by the State ofMaryland and Commonwealth of Pennsylvania have also named as defendants Energy Transfer Partners, L.P., ETP Holdco Corporation, and SunocoPartners Marketing & Terminals, L.P. Four of these cases are pending in a multidistrict litigation proceeding in a New York federal court; one is pendingin federal court in Rhode Island, one is pending in state court in Vermont, and one is pending in state court in Maryland.Sunoco, Inc. and Sunoco, Inc. (R&M) have reached a settlement with the State of New Jersey. The Court approved the Judicial Consent Order onDecember 5, 2017. Dismissal of the case against Sunoco, Inc. and Sunoco, Inc. (R&M) is expected shortly. The Maryland complaint was filed inDecember 2017 but was not served until January 2018.It is reasonably possible that a loss may be realized in the remaining cases; however, we are unable to estimate the possible loss or range of loss in excessof amounts accrued. An adverse determination with respect to one or more of the MTBE cases could have a significant impact on results of operationsduring the period in which any such adverse determination occurs, but such an adverse determination likely would not have a material adverse effect onthe Partnership’s consolidated financial position.Regency Merger LitigationFollowing the January 26, 2015 announcement of the Regency-ETP merger (the “Regency Merger”), purported Regency unitholders filed lawsuits instate and federal courts in Dallas and Delaware asserting claims relating to the Regency Merger. All but one Regency Merger-related lawsuits have beendismissed. On June 10, 2015, Adrian Dieckman (“Dieckman”), a purported Regency unitholder, filed a class action complaint, Dieckman v. Regency GPLP, et al., C.A. No. 11130-CB, in the Court of Chancery of the State of Delaware (the “Regency Merger Litigation”), on behalf of Regency’s commonunitholders against Regency GP, LP; Regency GP LLC; ETE, ETP, ETP GP, and the members of Regency’s board of directors (the “Regency LitigationDefendants”).The Regency Merger litigation alleges that the Regency Merger breached the Regency partnership agreement because Regency’s conflicts committeewas not properly formed, and the Regency Merger was not approved in good faith. On March 29, 2016, the Delaware Court of Chancery granted theRegency Litigation Defendants’ motion to dismiss the lawsuit in its entirety. Dieckman appealed. On January 20, 2017, the Delaware Supreme Courtreversed the judgment of the Court of Chancery. On May 5, 2017, Plaintiff filed an Amended Verified Class Action Complaint. The Regency LitigationDefendants then filed Motions to Dismiss the Amended Complaint and a Motion to Stay Discovery on May 19, 2017. On February 20, 2018, the Court ofChancery issued an Order granting in part and denying in part the motions to dismiss, dismissing the claims against all defendants other than RegencyGP, LP and Regency GP LLC.The Regency Litigation Defendants cannot predict the outcome of the Regency Merger Litigation or any lawsuits that might be filed subsequent to thedate of this filing; nor can the Regency Litigation Defendants predict the amount of time and expense that will be required to resolve the RegencyMerger Litigation. The Regency Litigation Defendants believe the Regency Merger Litigation is without merit and intend to vigorously defend againstit and any others that may be filed in connection with the Regency Merger.F - 51 Table of ContentsEnterprise Products Partners, L.P. and Enterprise Products Operating LLC LitigationOn January 27, 2014, a trial commenced between ETP against Enterprise Products Partners, L.P. and Enterprise Products Operating LLC (collectively,“Enterprise”) and Enbridge (US) Inc. Trial resulted in a verdict in favor of ETP against Enterprise that consisted of $319 million in compensatorydamages and $595 million in disgorgement to ETP. The jury also found that ETP owed Enterprise $1 million under a reimbursement agreement. On July29, 2014, the trial court entered a final judgment in favor of ETP and awarded ETP $536 million, consisting of compensatory damages, disgorgement,and pre-judgment interest. The trial court also ordered that ETP shall be entitled to recover post-judgment interest and costs of court and that Enterpriseis not entitled to any net recovery on its counterclaims. Enterprise filed a notice of appeal with the Court of Appeals. On July 18, 2017, the Court ofAppeals issued its opinion and reversed the trial court’s judgment. ETP’s motion for rehearing to the Court of Appeals was denied. ETP filed a petitionfor review with the Texas Supreme Court. Enterprise’s response is due February 26, 2018.Sunoco Logistics Merger LitigationSeven purported Energy Transfer Partners, L.P. common unitholders (the “ETP Unitholder Plaintiffs”) separately filed seven putative unitholder classaction lawsuits against ETP, ETP GP, ETP LLC, the members of the ETP Board, and ETE (the “ETP-SXL Defendants”) in connection with theannouncement of the Sunoco Logistics Merger. Two of these lawsuits were voluntarily dismissed in March 2017. The five remaining lawsuits wereconsolidated as In re Energy Transfer Partners, L.P. Shareholder Litig., C.A. No. 1:17-cv-00044-CCC, in the United States District Court for the Districtof Delaware (the “Sunoco Logistics Merger Litigation”). The ETP Unitholder Plaintiffs allege causes of action challenging the merger and the proxystatement/prospectus filed in connection with the Sunoco Logistics Merger (the “ETP-SXL Merger Proxy”). The ETP Unitholder Plaintiffs soughtrescission of the Sunoco Logistics Merger or rescissory damages for ETP unitholders, as well as an award of costs and attorneys’ fees. On October 5, 2017,the ETP-SXL Defendants filed a Motion to Dismiss the ETP Unitholder Plaintiffs’ claims. Rather than respond to the Motion to Dismiss, the ETPUnitholder Plaintiffs chose to voluntarily dismiss their claims without prejudice in November 2017.The ETP-SXL Defendants cannot predict whether the ETP Unitholder Plaintiffs will refile their claims against the ETP-SXL Defendants or what theoutcome of any such lawsuits might be. Nor can the ETP-SXL Defendants predict the amount of time and expense that would be required to resolve suchlawsuits. The ETP-SXL Defendants believe the Sunoco Logistics Merger Litigation was without merit and intend to defend vigorously against any futurelawsuits challenging the Sunoco Logistics Merger.Litigation filed by BP ProductsOn April 30, 2015, BP Products North America Inc. (“BP”) filed a complaint with the FERC, BP Products North America Inc. v. Sunoco Pipeline L.P.,FERC Docket No. OR15-25-000, alleging that Sunoco Pipeline L.P. (“SPLP”), a wholly-owned subsidiary of ETP, entered into certain throughput anddeficiency (“T&D”) agreements with shippers other than BP regarding SPLP’s crude oil pipeline between Marysville, Michigan and Toledo, Ohio, andrevised its proration policy relating to that pipeline in an unduly discriminatory manner in violation of the Interstate Commerce Act (“ICA”). Thecomplaint asked FERC to (1) terminate the agreements with the other shippers, (2) revise the proration policy, (3) order SPLP to restore BP’s volumehistory to the level that existed prior to the execution of the agreements with the other shippers, and (4) order damages to BP of approximately $62million, a figure that BP reduced in subsequent filings to approximately $41 million.SPLP denied the allegations in the complaint and asserted that neither its contracts nor proration policy were unlawful and that BP’s complaint wasbarred by the ICA’s two-year statute of limitations provision. Interventions were filed by the two companies with which SPLP entered into T&Dagreements, Marathon Petroleum Company (“Marathon”) and PBF Holding Company and Toledo Refining Company (collectively, “PBF”). A hearingon the matter was held in November 2016.On May 26, 2017, the Administrative Law Judge Patricia E. Hurt (“ALJ”) issued its initial decision (“Initial Decision”) and found that SPLP had acteddiscriminatorily by entering into T&D agreements with the two shippers other than BP and recommended that the FERC (1) adopt the FERC Trial Staff’s$13 million alternative damages proposal, (2) void the T&D agreements with Marathon and PBF, (3) re-set each shipper’s volume history to the levelprior to the effective date of the proration policy, and (4) investigate the proration policy. The ALJ held that BP’s claim for damages was not time-barredin its entirety, but that it was not entitled to damages more than two years prior to the filing of the complaint.On July 26, 2017, each of the parties filed with the FERC a brief on exceptions to the Initial Decision. SPLP challenged all of the Initial Decision’sprimary findings (except for the adjustment to the individual shipper volume histories). BP and FERC Trial Staff challenged various aspects of the InitialDecision related to remedies and the statute of limitations issue. On September 18 and 19, 2017, all parties filed briefs opposing the exceptions of theother parties. The matter is now awaiting a decision by FERC.F - 52 Table of ContentsOther Litigation and ContingenciesWe or our subsidiaries are a party to various legal proceedings and/or regulatory proceedings incidental to our businesses. For each of these matters, weevaluate the merits of the case, our exposure to the matter, possible legal or settlement strategies, the likelihood of an unfavorable outcome and theavailability of insurance coverage. If we determine that an unfavorable outcome of a particular matter is probable and can be estimated, we accrue thecontingent obligation, as well as any expected insurance recoverable amounts related to the contingency. As of December 31, 2017 and 2016, accruals ofapproximately $33 million and $77 million, respectively, were reflected on our consolidated balance sheets related to these contingent obligations. Asnew information becomes available, our estimates may change. The impact of these changes may have a significant effect on our results of operations ina single period.The outcome of these matters cannot be predicted with certainty and there can be no assurance that the outcome of a particular matter will not result inthe payment of amounts that have not been accrued for the matter. Furthermore, we may revise accrual amounts prior to resolution of a particularcontingency based on changes in facts and circumstances or changes in the expected outcome. Currently, we are not able to estimate possible losses or arange of possible losses in excess of amounts accrued.No amounts have been recorded in our December 31, 2017 or 2016 consolidated balance sheets for contingencies and current litigation, other thanamounts disclosed herein.Environmental MattersOur operations are subject to extensive federal, tribal, state and local environmental and safety laws and regulations that require expenditures to ensurecompliance, including related to air emissions and wastewater discharges, at operating facilities and for remediation at current and former facilities aswell as waste disposal sites. Historically, our environmental compliance costs have not had a material adverse effect on our results of operations but therecan be no assurance that such costs will not be material in the future or that such future compliance with existing, amended or new legal requirementswill not have a material adverse effect on our business and operating results. Costs of planning, designing, constructing and operating pipelines, plantsand other facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws andregulations may result in the assessment of administrative, civil and criminal penalties, the imposition of investigatory, remedial and corrective actionobligations, the issuance of injunctions in affected areas and the filing of federally authorized citizen suits. Contingent losses related to all significantknown environmental matters have been accrued and/or separately disclosed. However, we may revise accrual amounts prior to resolution of a particularcontingency based on changes in facts and circumstances or changes in the expected outcome.Environmental exposures and liabilities are difficult to assess and estimate due to unknown factors such as the magnitude of possible contamination, thetiming and extent of remediation, the determination of our liability in proportion to other parties, improvements in cleanup technologies and the extentto which environmental laws and regulations may change in the future. Although environmental costs may have a significant impact on the results ofoperations for any single period, we believe that such costs will not have a material adverse effect on our financial position.Based on information available at this time and reviews undertaken to identify potential exposure, we believe the amount reserved for environmentalmatters is adequate to cover the potential exposure for cleanup costs.In February 2017, we received letters from the DOJ and Louisiana Department of Environmental Quality notifying Sunoco Pipeline L.P. (“SPLP”) andMid-Valley Pipeline Company (“Mid-Valley”) that enforcement actions were being pursued for three crude oil releases: (a) an estimated 550 barrelsreleased from the Colmesneil-to-Chester pipeline in Tyler County, Texas (“Colmesneil”) operated and owned by SPLP in February of 2013; (b) anestimated 4,509 barrels released from the Longview-to-Mayersville pipeline in Caddo Parish, Louisiana (a/k/a Milepost 51.5) operated by SPLP andowned by Mid-Valley in October of 2014; and (c) an estimated 40 barrels released from the Wakita 4-inch gathering line in Oklahoma operated andowned by SPLP in January of 2015. In May of this year, we presented to the DOJ, EPA and Louisiana Department of Environmental Quality a summary ofthe emergency response and remedial efforts taken by SPLP after the releases occurred as well as operational changes instituted by SPLP to reduce thelikelihood of future releases. In July, we had a follow-up meeting with the DOJ, EPA and Louisiana Department of Environmental Quality during whichthe agencies presented their initial demand for civil penalties and injunctive relief. In short, the DOJ and EPA proposed federal penalties totaling$7 million for the three releases along with a demand for injunctive relief, and Louisiana Department of Environmental Quality proposed a state penaltyof approximately $1 million to resolve the Caddo Parish release. Neither Texas nor Oklahoma state agencies have joined the penalty discussions at thispoint. We are currently working on a counteroffer to the Louisiana Department of Environmental Quality.On January 3, 2018, PADEP issued an Administrative Order to Sunoco Pipeline L.P. directing that work on the Mariner East 2 and 2X pipelines bestopped. The Administrative Order detailed alleged violations of the permits issued by PADEP inF - 53 Table of ContentsFebruary of 2017, during the construction of the project. Sunoco Pipeline L.P. began working with PADEP representatives immediately after theAdministrative Order was issued to resolve the compliance issues. Those compliance issues could not be fully resolved by the deadline to appeal theAdministrative Order, so Sunoco Pipeline L.P. took an appeal of the Administrative Order to the Pennsylvania Environmental Hearing Board on February2, 2018. On February 8, 2018, Sunoco Pipeline L.P. entered into a Consent Order and Agreement with PADEP that (1) withdraws the AdministrativeOrder; (2) establishes requirements for compliance with permits on a going forward basis; (3) resolves the non-compliance alleged in the AdministrativeOrder; and (4) conditions restart of work on an agreement by Sunoco Pipeline L.P. to pay a $12.6 million civil penalty to the Commonwealth ofPennsylvania. In the Consent Order and agreement, Sunoco Pipeline L.P. admits to the factual allegations, but does not admit to the conclusions of lawthat were made by PADEP. PADEP also found in the Consent Order and Agreement that Sunoco Pipeline L.P. had adequately addressed the issues raisedin the Administrative Order and demonstrated an ability to comply with the permits. Sunoco Pipeline L.P. concurrently filed a request to thePennsylvania Environmental Hearing Board to discontinue the appeal of the Administrative Order. That request was granted on February 8, 2018.Environmental RemediationOur subsidiaries are responsible for environmental remediation at certain sites, including the following:•Certain of our interstate pipelines conduct soil and groundwater remediation related to contamination from past uses of PCBs. PCB assessments areongoing and, in some cases, our subsidiaries could potentially be held responsible for contamination caused by other parties.•Certain gathering and processing systems are responsible for soil and groundwater remediation related to releases of hydrocarbons.•Legacy sites related to Sunoco, Inc. that are subject to environmental assessments, including formerly owned terminals and other logistics assets,retail sites that Sunoco, Inc. no longer operates, closed and/or sold refineries and other formerly owned sites.•Sunoco, Inc. is potentially subject to joint and several liability for the costs of remediation at sites at which it has been identified as a potentiallyresponsible party (“PRP”). As of December 31, 2017, Sunoco, Inc. had been named as a PRP at approximately 43 identified or potentiallyidentifiable “Superfund” sites under federal and/or comparable state law. Sunoco, Inc. is usually one of a number of companies identified as a PRP ata site. Sunoco, Inc. has reviewed the nature and extent of its involvement at each site and other relevant circumstances and, based upon Sunoco,Inc.’s purported nexus to the sites, believes that its potential liability associated with such sites will not be significant.To the extent estimable, expected remediation costs are included in the amounts recorded for environmental matters in our consolidated balance sheets.In some circumstances, future costs cannot be reasonably estimated because remediation activities are undertaken as claims are made by customers andformer customers. To the extent that an environmental remediation obligation is recorded by a subsidiary that applies regulatory accounting policies,amounts that are expected to be recoverable through tariffs or rates are recorded as regulatory assets on our consolidated balance sheets.The table below reflects the amounts of accrued liabilities recorded in our consolidated balance sheets related to environmental matters that areconsidered to be probable and reasonably estimable. Currently, we are not able to estimate possible losses or a range of possible losses in excess ofamounts accrued. Except for matters discussed above, we do not have any material environmental matters assessed as reasonably possible that wouldrequire disclosure in our consolidated financial statements. December 31, 2017 2016Current$36 $26Non-current314 283Total environmental liabilities$350 $309In 2013, we established a wholly-owned captive insurance company to bear certain risks associated with environmental obligations related to certainsites that are no longer operating. The premiums paid to the captive insurance company include estimates for environmental claims that have beenincurred but not reported, based on an actuarially determined fully developed claims expense estimate. In such cases, we accrue losses attributable tounasserted claims based on the discounted estimates that are used to develop the premiums paid to the captive insurance company.F - 54 Table of ContentsDuring the years ended December 31, 2017 and 2016, the Partnership recorded $23 million and $43 million, respectively, of expenditures related toenvironmental cleanup programs.On December 2, 2010, Sunoco, Inc. entered an Asset Sale and Purchase Agreement to sell the Toledo Refinery to Toledo Refining Company LLC(“TRC”) wherein Sunoco, Inc. retained certain liabilities associated with the pre-closing time period. On January 2, 2013, USEPA issued a Finding ofViolation (“FOV”) to TRC and, on September 30, 2013, EPA issued a Notice of Violation (“NOV”)/ FOV to TRC alleging Clean Air Act violations. Todate, EPA has not issued an FOV or NOV/FOV to Sunoco, Inc. directly but some of EPA’s claims relate to the time period that Sunoco, Inc. operated therefinery. Specifically, EPA has claimed that the refinery flares were not operated in a manner consistent with good air pollution control practice forminimizing emissions and/or in conformance with their design, and that Sunoco, Inc. submitted semi-annual compliance reports in 2010 and 2011 to theEPA that failed to include all of the information required by the regulations. EPA has proposed penalties in excess of $200,000 to resolve the allegationsand discussions continue between the parties. The timing or outcome of this matter cannot be reasonably determined at this time, however, we do notexpect there to be a material impact to our results of operations, cash flows or financial position.Our pipeline operations are subject to regulation by the United States Department of Transportation under the PHMSA, pursuant to which the PHMSAhas established requirements relating to the design, installation, testing, construction, operation, replacement and management of pipeline facilities.Moreover, the PHMSA, through the Office of Pipeline Safety, has promulgated a rule requiring pipeline operators to develop integrity managementprograms to comprehensively evaluate their pipelines, and take measures to protect pipeline segments located in what the rule refers to as “highconsequence areas.” Activities under these integrity management programs involve the performance of internal pipeline inspections, pressure testing orother effective means to assess the integrity of these regulated pipeline segments, and the regulations require prompt action to address integrity issuesraised by the assessment and analysis. Integrity testing and assessment of all of these assets will continue, and the potential exists that results of suchtesting and assessment could cause us to incur future capital and operating expenditures for repairs or upgrades deemed necessary to ensure thecontinued safe and reliable operation of our pipelines; however, no estimate can be made at this time of the likely range of such expenditures.In January 2012, we experienced a release on our products pipeline in Wellington, Ohio. In connection with this release, the PHMSA issued a CorrectiveAction Order under which we are obligated to follow specific requirements in the investigation of the release and the repair and reactivation of thepipeline. This PHMSA Corrective Action Order was closed via correspondence dated November 4, 2016. No civil penalties were associated with thePHMSA Order. We also entered into an Order on Consent with the EPA regarding the environmental remediation of the release site. All requirements ofthe Order on Consent with the EPA have been fulfilled and the Order has been satisfied and closed. We have also received a “No Further Action”approval from the Ohio EPA for all soil and groundwater remediation requirements. In May 2016, we received a proposed penalty from the EPA and DOJassociated with this release, and continues to work with the involved parties to bring this matter to closure. The timing and outcome of this matter cannotbe reasonably determined at this time. However, we do not expect there to be a material impact to our results of operations, cash flows or financialposition.In October 2016, the PHMSA issued a Notice of Probable Violation (“NOPVs”) and a Proposed Compliance Order (“PCO”) related to our West TexasGulf pipeline in connection with repairs being carried out on the pipeline and other administrative and procedural findings. The proposed penalty is inexcess of $100,000. The case went to hearing in March 2017 and remains open with PHMSA. We do not expect there to be a material impact to ourresults of operations, cash flows or financial position.In April 2016, the PHMSA issued a NOPV, PCO and Proposed Civil Penalty related to certain procedures carried out during construction of our PermianExpress 2 pipeline system in Texas. The proposed penalties are in excess of $100,000. The case went to Hearing in November 2016 and remains openwith PHMSA. We do not expect there to be a material impact to our results of operations, cash flows or financial position.In July 2016, the PHMSA issued a NOPV and PCO to our West Texas Gulf pipeline in connection with inspection and maintenance activities related to a2013 incident on our crude oil pipeline near Wortham, Texas. The proposed penalties are in excess of $100,000. The case went to hearing in March 2017and remains open with PHMSA. We do not expect there to be a material impact to our results of operations, cash flows, or financial position.In August 2017, the PHMSA issued a NOPV and a PCO in connection with alleged violations on our Nederland to Kilgore pipeline in Texas. The caseremains open with PHMSA and the proposed penalties are in excess of $100,000. We do not expect there to be a material impact to our results ofoperations, cash flows or financial position.Our operations are also subject to the requirements of the federal OSHA, and comparable state laws that regulate the protection of the health and safety ofemployees. In addition, Occupational Safety and Health Administration’s hazardous communication standard requires that information be maintainedabout hazardous materials used or produced in our operations and that this information be provided to employees, state and local government authoritiesand citizens. We believe that our past costs forF - 55 Table of ContentsOSHA required activities, including general industry standards, record keeping requirements, and monitoring of occupational exposure to regulatedsubstances have not had a material adverse effect on our results of operations but there is no assurance that such costs will not be material in the future.12.DERIVATIVE ASSETS AND LIABILITIES:Commodity Price RiskWe are exposed to market risks related to the volatility of commodity prices. To manage the impact of volatility from these prices, we utilize variousexchange-traded and OTC commodity financial instrument contracts. These contracts consist primarily of futures, swaps and options and are recorded atfair value in our consolidated balance sheets.We use futures and basis swaps, designated as fair value hedges, to hedge our natural gas inventory stored in our Bammel storage facility. At hedgeinception, we lock in a margin by purchasing gas in the spot market or off peak season and entering into a financial contract. Changes in the spreadsbetween the forward natural gas prices and the physical inventory spot price result in unrealized gains or losses until the underlying physical gas iswithdrawn and the related designated derivatives are settled. Once the gas is withdrawn and the designated derivatives are settled, the previouslyunrealized gains or losses associated with these positions are realized.We use futures, swaps and options to hedge the sales price of natural gas we retain for fees in our intrastate transportation and storage segment andoperational gas sales on our interstate transportation and storage segment. These contracts are not designated as hedges for accounting purposes.We use NGL and crude derivative swap contracts to hedge forecasted sales of NGL and condensate equity volumes we retain for fees in our midstreamsegment whereby our subsidiaries generally gather and process natural gas on behalf of producers, sell the resulting residue gas and NGL volumes atmarket prices and remit to producers an agreed upon percentage of the proceeds based on an index price for the residue gas and NGL. These contracts arenot designated as hedges for accounting purposes.We utilize swaps, futures and other derivative instruments to mitigate the risk associated with market movements in the price of refined products andNGLs to manage our storage facilities and the purchase and sale of purity NGL. These contracts are not designated as hedges for accounting purposes.We use financial commodity derivatives to take advantage of market opportunities in our trading activities which complement our transportation andstorage segment’s operations and are netted in cost of products sold in our consolidated statements of operations. We also have trading and marketingactivities related to power and natural gas in our all other segment which are also netted in cost of products sold. As a result of our trading activities andthe use of derivative financial instruments in our transportation and storage segment, the degree of earnings volatility that can occur may be significant,favorably or unfavorably, from period to period. We attempt to manage this volatility through the use of daily position and profit and loss reportsprovided to our risk oversight committee, which includes members of senior management, and the limits and authorizations set forth in our commodityrisk management policy.F - 56 Table of ContentsThe following table details our outstanding commodity-related derivatives: December 31, 2017 December 31, 2016 NotionalVolume Maturity NotionalVolume MaturityMark-to-Market Derivatives (Trading) Natural Gas (BBtu): Fixed Swaps/Futures1,078 2018 (683) 2017Basis Swaps IFERC/NYMEX(1)48,510 2018-2020 2,243 2017Options – Calls13,000 2018 — —Power (Megawatt): Forwards435,960 2018-2019 391,880 2017-2018Futures(25,760) 2018 109,564 2017-2018Options – Puts(153,600) 2018 (50,400) 2017Options – Calls137,600 2018 186,400 2017Crude (MBbls) – Futures— — (617) 2017(Non-Trading) Natural Gas (BBtu): Basis Swaps IFERC/NYMEX4,650 2018-2020 10,750 2017-2018Swing Swaps IFERC87,253 2018-2019 (5,663) 2017Fixed Swaps/Futures(4,700) 2018-2019 (52,653) 2017-2019Forward Physical Contracts(145,105) 2018-2020 (22,492) 2017Natural Gas Liquid (MBbls) – Forwards/Swaps6,679 2018-2019 (5,787) 2017Refined Products (MBbls) – Futures(3,783) 2018-2019 (2,240) 2017Fair Value Hedging Derivatives (Non-Trading) Natural Gas (BBtu): Basis Swaps IFERC/NYMEX(39,770) 2018 (36,370) 2017Fixed Swaps/Futures(39,770) 2018 (36,370) 2017Hedged Item – Inventory39,770 2018 36,370 2017(1) Includes aggregate amounts for open positions related to Houston Ship Channel, Waha Hub, NGPL TexOk, West Louisiana Zone and Henry Hublocations.Interest Rate RiskWe are exposed to market risk for changes in interest rates. To maintain a cost effective capital structure, we borrow funds using a mix of fixed rate debtand variable rate debt. We also manage our interest rate exposure by utilizing interest rate swaps to achieve a desired mix of fixed and variable rate debt.We also utilize forward starting interest rate swaps to lock in the rate on a portion of our anticipated debt issuances.F - 57 Table of ContentsThe following table summarizes our interest rate swaps outstanding, none of which were designated as hedges for accounting purposes:Term Type(1) Notional Amount OutstandingDecember 31, 2017 December 31, 2016July 2017(2) Forward-starting to pay a fixed rate of 3.90% and receive a floating rate $— $500July 2018(2) Forward-starting to pay a fixed rate of 3.76% and receive a floating rate 300 200July 2019(2) Forward-starting to pay a fixed rate of 3.64% and receive a floating rate 300 200July 2020(2) Forward-starting to pay a fixed rate of 3.52% and receive a floating rate 400 —December 2018 Pay a floating rate based on a 3-month LIBOR and receive a fixed rate of1.53% 1,200 1,200March 2019 Pay a floating rate based on a 3-month LIBOR and receive a fixed rate of1.42% 300 300(1) Floating rates are based on 3-month LIBOR. (2) Represents the effective date. These forward-starting swaps have terms of 30 years with a mandatory termination date the same as the effective date. Credit RiskCredit risk refers to the risk that a counterparty may default on its contractual obligations resulting in a loss to the Partnership. Credit policies have beenapproved and implemented to govern the Partnership’s portfolio of counterparties with the objective of mitigating credit losses. These policies establishguidelines, controls and limits to manage credit risk within approved tolerances by mandating an appropriate evaluation of the financial condition ofexisting and potential counterparties, monitoring agency credit ratings, and by implementing credit practices that limit exposure according to the riskprofiles of the counterparties. Furthermore, the Partnership may, at times, require collateral under certain circumstances to mitigate credit risk asnecessary. The Partnership also uses industry standard commercial agreements which allow for the netting of exposures associated with transactionsexecuted under a single commercial agreement. Additionally, we utilize master netting agreements to offset credit exposure across multiple commercialagreements with a single counterparty or affiliated group of counterparties.The Partnership’s counterparties consist of a diverse portfolio of customers across the energy industry, including petrochemical companies, commercialand industrials, oil and gas producers, municipalities, gas and electric utilities, midstream companies and independent power generators. Our overallexposure may be affected positively or negatively by macroeconomic or regulatory changes that impact our counterparties to one extent or another.Currently, management does not anticipate a material adverse effect in our financial position or results of operations as a consequence of counterpartynon-performance.The Partnership has maintenance margin deposits with certain counterparties in the OTC market, primarily independent system operators, and withclearing brokers. Payments on margin deposits are required when the value of a derivative exceeds our pre-established credit limit with the counterparty.Margin deposits are returned to us on or about the settlement date for non-exchange traded derivatives, and we exchange margin calls on a daily basis forexchange traded transactions. Since the margin calls are made daily with the exchange brokers, the fair value of the financial derivative instruments aredeemed current and netted in deposits paid to vendors within other current assets in the consolidated balance sheets.For financial instruments, failure of a counterparty to perform on a contract could result in our inability to realize amounts that have been recorded onour consolidated balance sheets and recognized in net income or other comprehensive income.F - 58 Table of ContentsDerivative SummaryThe following table provides a summary of our derivative assets and liabilities: Fair Value of Derivative Instruments Asset Derivatives Liability Derivatives December 31,2017 December 31,2016 December 31,2017 December 31,2016Derivatives designated as hedging instruments: Commodity derivatives (margin deposits)$14 $— $(2) $(4) 14 — (2) (4)Derivatives not designated as hedging instruments: Commodity derivatives (margin deposits)262 338 (281) (416)Commodity derivatives44 24 (55) (52)Interest rate derivatives— — (219) (193)Embedded derivatives in Legacy ETP Preferred Units— — — (1) 306 362 (555) (662)Total derivatives$320 $362 $(557) $(666)The following table presents the fair value of our recognized derivative assets and liabilities on a gross basis and amounts offset on the consolidatedbalance sheets that are subject to enforceable master netting arrangements or similar arrangements: Asset Derivatives Liability Derivatives Balance Sheet Location December 31, 2017 December 31, 2016 December 31, 2017 December 31, 2016Derivatives withoutoffsetting agreements Derivative liabilities $— $— $(219) $(194)Derivatives in offsetting agreements: OTC contracts Derivative assets(liabilities) 44 24 (55) (52)Broker cleared derivativecontracts Other current assets(liabilities) 276 338 (283) (420) 320 362 (557) (666)Offsetting agreements: Counterparty netting Derivative assets(liabilities) (20) (4) 20 4Counterparty netting Other current assets(liabilities) (263) (338) 263 338Total net derivatives $37 $20 $(274) $(324)We disclose the non-exchange traded financial derivative instruments as price risk management assets and liabilities on our consolidated balance sheetsat fair value with amounts classified as either current or long-term depending on the anticipated settlement date.F - 59 Table of ContentsThe following tables summarize the amounts recognized with respect to our derivative financial instruments: Location of Gain/(Loss)Recognized in Income onDerivatives Amount of Gain (Loss) Recognized in IncomeRepresenting Hedge Ineffectiveness and AmountExcluded from the Assessment of Effectiveness Years Ended December 31, 2017 2016 2015Derivatives in fair value hedgingrelationships (including hedged item): Commodity derivativesCost of products sold $26 $14 $21Total $26 $14 $21 Location of Gain/(Loss)Recognized in Income onDerivatives Amount of Gain (Loss) Recognized in Income onDerivatives Years Ended December 31, 2017 2016 2015Derivatives not designated as hedginginstruments: Commodity derivatives – TradingCost of products sold $31 $(35) $(11)Commodity derivatives – Non-tradingCost of products sold 3 (173) 23Interest rate derivativesLosses on interest rate derivatives (37) (12) (18)Embedded derivativesOther, net 1 4 12Total $(2) $(216) $613.RETIREMENT BENEFITS:Savings and Profit Sharing PlansWe and our subsidiaries sponsor defined contribution savings and profit sharing plans, which collectively cover virtually all eligible employees.Employer matching contributions are calculated using a formula based on employee contributions. We and our subsidiaries made matchingcontributions of $38 million, $44 million and $39 million to these 401(k) savings plans for the years ended December 31, 2017, 2016, and 2015,respectively.Pension and Other Postretirement Benefit PlansPanhandlePostretirement benefits expense for the years ended December 31, 2017, 2016 and 2015 reflect the impact of changes Panhandle or its affiliates adoptedas of September 30, 2013, to modify its retiree medical benefits program, effective January 1, 2014. The modification placed all eligible retirees on acommon medical benefit platform, subject to limits on Panhandle’s annual contribution toward eligible retirees’ medical premiums. Prior to January 1,2013, affiliates of Panhandle offered postretirement health care and life insurance benefit plans (other postretirement plans) that covered substantially allemployees. Effective January 1, 2013, participation in the plan was frozen and medical benefits were no longer offered to non-union employees.Effective January 1, 2014, retiree medical benefits were no longer offered to union employees.Sunoco, Inc.Sunoco, Inc. sponsors a defined benefit pension plan, which was frozen for most participants on June 30, 2010. On October 31, 2014, Sunoco, Inc.terminated the plan, and paid lump sums to eligible active and terminated vested participants in December 2015.Sunoco, Inc. also has a plan which provides health care benefits for substantially all of its current retirees. The cost to provide the postretirement benefitplan is shared by Sunoco, Inc. and its retirees. Access to postretirement medical benefits was phasedF - 60 Table of Contentsout or eliminated for all employees retiring after July 1, 2010. In March, 2012, Sunoco, Inc. established a trust for its postretirement benefit liabilities.Sunoco made a tax-deductible contribution of approximately $200 million to the trust. The funding of the trust eliminated substantially all of Sunoco,Inc.’s future exposure to variances between actual results and assumptions used to estimate retiree medical plan obligations.Obligations and Funded StatusPension and other postretirement benefit liabilities are accrued on an actuarial basis during the years an employee provides services.

To achieve diversity withinits other postretirement plan asset portfolio, Panhandle has targeted the following asset allocations: equity of 25% to 35%, fixed income of 65% to 75%.The investment strategy of Sunoco, Inc. funded defined benefit plans is to achieve consistent positive returns, after adjusting for inflation, and tomaximize long-term total return within prudent levels of risk through a combination of income and capital appreciation. The objective of this strategy isto reduce the volatility of investment returns and maintain a sufficient funded status of the plans. In anticipation of the pension plan termination,Sunoco, Inc. targeted the asset allocations to a more stable position by investing in growth assets and liability hedging assets.The fair value of the pension plan assets by asset category at the dates indicated is as follows: Fair Value Measurements at December 31, 2017 Fair Value Total Level 1 Level 2 Level 3Asset category: Mutual funds(1)$1 $1 $— $—Total$1 $1 $— $—(1) Comprised of approximately 100% equities as of December 31, 2017.

ContributionsWe expect to contribute $8 million to pension plans and $10 million to other postretirement plans in 2018. The cost of the plans are funded inaccordance with federal regulations, not to exceed the amounts deductible for income tax purposes.Benefit PaymentsPanhandle and Sunoco, Inc.’s estimate of expected benefit payments, which reflect expected future service, as appropriate, in each of the next five yearsand in the aggregate for the five years thereafter are shown in the table below:Years Pension Benefits - Unfunded Plans (1) Other Postretirement Benefits (Gross, BeforeMedicare Part D)2018 $8 $242019 6 232020 6 212021 5 192022 4 172023 – 2027 15 37(1) Expected benefit payments of funded pension plans are less than $1 million for the next ten years.The Medicare Prescription Drug Act provides for a prescription drug benefit under Medicare (“Medicare Part D”) as well as a federal subsidy to sponsorsof retiree health care benefit plans that provide a prescription drug benefit that is at least actuarially equivalent to Medicare Part D.Panhandle does not expect to receive any Medicare Part D subsidies in any future periods.F - 64 Table of Contents14.RELATED PARTY TRANSACTIONS:In June 2017, the Partnership acquired all of the publicly held PennTex common units through a tender offer and exercise of a limited call right, asfurther discussed in Note 8.ETE previously paid us to provide services on its behalf and on behalf of other subsidiaries of ETE, which included the reimbursement of variousoperating and general and administrative expenses incurred by us on behalf of ETE and its subsidiaries. These agreements expired in 2016.The Partnership also has related party transactions with several of its equity method investees.

Due to the transfer of the general partner interest ofSunoco LP from ETP to ETE in 2015 and completion of the dropdown of remaining Retail Marketing interests from ETP to Sunoco LP in March 2016,all of the Partnership’s retail marketing business has been deconsolidated. The only remaining retail marketing assets are the limited partner units ofSunoco LP. As of December 31, 2017, the Partnership’s interest in Sunoco LP common units consisted of 43.5 million units, representing 43.6% ofSunoco LP’s total outstanding common units. Subsequent to Sunoco LP’s repurchase of a portion of its common units on February 7, 2018, ourinvestment consists of 26.2 million units, representing 31.8% of Sunoco LP’s total outstanding common units. This equity method investment in SunocoLP has now been aggregated into the all other segment. Consequently, the retail marketing business that was previously consolidated has also beenaggregated in the all other segment for all periods presented.Consolidated revenues and expenses reflect the elimination of all material intercompany transactions.Revenues from our intrastate transportation and storage segment are primarily reflected in natural gas sales and gathering, transportation and other fees.Revenues from our interstate transportation and storage segment are primarily reflected in gathering, transportation and other fees.

As stated in Note 2 to those financial statements, the Partnership changed its accounting for inventory costingfrom the last-in, first-out (LIFO) method to the weighted average cost method for all legacy Sunoco Logistics Partners L.P. inventory. Note 2 also statesmanagement’s belief that the newly adopted accounting principle is preferable in the circumstances because it more closely aligns with the accountingpolicies across the consolidated entity, given that the other entities are accounting for inventory costing using the weighted average cost method.With regard to the aforementioned accounting change, it should be understood that authoritative criteria have not been established for evaluating thepreferability of one acceptable method of accounting over another acceptable method and, in expressing our concurrence below, we have relied onmanagement’s business planning and judgment and on management’s determination that this change in accounting principle is preferable.Based on our reading of management’s stated reasons and justification for this change in accounting principle in the Form 10-K, and our discussions withmanagement as to their judgment about the relevant business planning factors relating to the change, we concur with management that the newly adoptedmethod of accounting is preferable in the Partnership’s circumstances.Sincerely,/s/ GRANT THORNTON LLPDallas, Texas Exhibit 21.1LIST OF SUBSIDIARIESSUBSIDIARIES OF ENERGY TRANSFER PARTNERS, L.P., a Delaware limited partnership:Advanced Diesel LLC, a Idaho limited liability companyAdvanced Meter Solutions LLC, a Delaware limited liability companyAqua-ETC Water Solutions, LLC, a Delaware limited liability companyArguelles Pipeline S de R.L.
