Weintend to accomplish these objectives by executing the following strategies:•Focus on building a vertically integrated midstream master limited partnership providing multiple services to customers. We continue toenhance our ability to transport crude oil from the wellhead to refiners, refined products from refiners to customers, wastewater from thewellhead to treatment for disposal, recycle, or discharge, and natural gas liquids from processing plants to end users, including retail propanecustomers.•Achieve organic growth by investing in new assets that increase volumes, enhance our operations, and generate attractive rates of return. Webelieve that there are accretive organic growth opportunities that originate from assets we own and operate. We have invested and expect tocontinue to invest within our existing businesses, particularly within our Crude Oil Logistics and Water Solutions businesses as we grow thesebusinesses with highly accretive, fee-based organic growth opportunities.•Deliver accretive growth through strategic acquisitions that complement our existing business model and expand our operations. We intend tocontinue to pursue acquisitions that build upon our vertically integrated business model, add scale to our current operating platforms, andenhance our geographic diversity in our businesses. We have established a successful track record of acquiring companies and assets atattractive prices and we continue to evaluate acquisition opportunities in order to capitalize on this strategy in the future.•Focus on consistent annual cash flows by adding operations that minimize commodity price risk and generate fee-based, cost-plus, or margin-based revenues under multi-year contracts. We intend to focus on long-term fee-based contracts in addition to back-to-back contracts whichminimize commodity price exposure. We continue to increase cash flows that are supported by certain fee-based, multi-year contracts, some ofwhich include acreage dedications from producers or volume commitments.•Maintain a disciplined cash distribution policy that complements our leverage, acquisition and organic growth strategies. We target leveragelevels that are consistent with those of investment grade companies. We expect to maintain sufficient leverage, liquidity and other credit metricsto manage existing and future capital requirements and to take advantage of market opportunities.Our Competitive StrengthsWe believe that we are well positioned to successfully execute our business strategies and achieve our principal business objectives because of thefollowing competitive strengths:•Our vertically integrated and diversified operations, which help us generate more predictable and stable cash flows on a year-to-year basis.Our ability to provide multiple services to customers in numerous geographic areas enhances our competitive position. Our five business unitsare diversified by geography, customer-base and commodity sensitivities which we believe provides us with the ability to maintain cash flowsthroughout typical commodity cycles. For example, our Retail Propane business sources propane through our Liquids business which allows usto leverage the expertise of our Liquids business to help improve our margins and profitability and enhance our cash flows. Furthermore, webelieve that our Liquids business provides us with valuable market intelligence that helps us identify potential acquisition opportunities. OurRefined Products business benefits from lower energy prices driving increased customer demand, which can offset the downward pressure on ourCrude Oil Logistics and Water Solutions businesses in a low price environment.•Our network of crude oil transportation assets, which allows us to serve customers over a wide geographic area and optimize sales. Ourstrategically deployed railcar fleet, towboats, barges, and trucks, and our owned and contracted pipeline capacity, provide access to a widerange of customers and markets. We use this expansive network of transportation assets to deliver crude oil to the optimal markets.•Our water processing facilities, which are strategically located near areas of high crude oil and natural gas production. Our water processingfacilities are located among the most prolific crude oil and natural gas producing areas in the United States, including the Permian Basin, the DJBasin, the Eagle Ford shale play, the Bakken shale play, and the Pinedale Anticline. In addition, we believe that the technological capabilitiesof our Water Solutions business can be quickly implemented at new facilities and locations.9Table of Contents•Our network of natural gas liquids transportation, terminal, and storage assets, which allows us to provide multiple services over thecontinental United States. Our strategically located terminals, large railcar fleet, shipper status on common carrier pipelines, and substantialleased and owned underground storage enable us to be a preferred purchaser and seller of natural gas liquids.•Our high percentage of retail sales to residential customers, who are generally more stable purchasers of propane and distillates and generatehigher margins than other customers. Our high percentage of propane tank ownership, payment billing systems, and automatic deliveryprogram have resulted in a strong record of customer retention and help us better predict our cash flows in the Retail Propane business.•Our access to refined products pipeline and terminal infrastructure. Our capacity allocations on third-party pipelines and our proprietaryaccess to refined products terminals give us the opportunity to serve customers over a large geographic area.•Our seasoned management team with extensive midstream industry experience and a track record of acquiring, integrating, operating andgrowing successful businesses. Our management team has significant experience managing companies in the energy industry, including masterlimited partnerships. In addition, through decades of experience, our management team has developed strong business relationships with keyindustry participants throughout the United States. We believe that our management’s knowledge of the industry, relationships within theindustry, and experience in identifying, evaluating and completing acquisitions provides us with opportunities to grow through strategic andaccretive acquisitions that complement or expand our existing operations.Our BusinessesCrude Oil LogisticsOverview. Our Crude Oil Logistics segment purchases crude oil from producers and transports it to refineries or for resale at pipeline injectionstations, storage terminals, barge loading facilities, rail facilities, refineries, and other trade hubs, and provides storage, terminaling, trucking, marine andpipeline transportation services through its owned assets. Our operations are centered near areas of high crude oil production, such as the Bakken shale playin North Dakota, the DJ Basin in Colorado, the Permian Basin in Texas and New Mexico, the Eagle Ford shale play in Texas, the Anadarko Basin, includingthe STACK, SCOOP, Granite Wash and Mississippi Lime plays in Oklahoma and Texas, and southern Louisiana at the Gulf of Mexico.We own a 550-mile pipeline that transports crude oil from its origin in Colorado to Cushing, Oklahoma (the “Grand Mesa Pipeline”). Grand MesaPipeline commenced operations on November 1, 2016, and the main line portion of this pipe is comprised of a 37.5% undivided interest in a crude oilpipeline jointly owned with Saddlehorn Pipeline Company, LLC (“Saddlehorn”) where we have the right to utilize 150,000 barrels per day of capacity.During the year ended March 31, 2018, there were approximately 92,000 barrels per day transported on the Grand Mesa Pipeline. Operating costs areallocated to us based on our proportionate ownership interest and throughput. We also own 970,000 barrels of operational tankage related to the Grand MesaPipeline.Through our undivided interest in the Grand Mesa Pipeline, we have capacity sufficient to service our customer contracts at the same origin andtermination points with the ability to accept additional volume commitments. We retained ownership of our previously-acquired easements for the potentialfuture development of transportation projects involving petroleum commodities other than crude oil and condensate. With the consent and participation ofSaddlehorn, we and Saddlehorn may consider future opportunities using these easements for projects involving the transportation of crude oil andcondensate.Operations. We purchase crude oil from producers and transport it to refineries or for resale. Our strategically deployed railcar fleet, towboats, barges,and trucks, and our owned and contracted pipeline capacity, provide access to a wide range of customers and markets. We use this expansive network oftransportation assets to deliver crude oil to the optimal markets.We currently transport crude oil using the following assets:•163 owned trucks and 260 owned trailers operating primarily in the Mid-Continent, Permian Basin, Eagle Ford shale play, and Rocky Mountainregions;10Table of Contents•400 owned railcars and 397 leased railcars (of which 291 railcars are subleased to third parties) operating primarily in Colorado, Illinois, Kansas,Montana, Oklahoma, Texas, and Washington; and•10 owned towboats and 19 owned barges operating primarily in the intercoastal waterways of the Gulf Coast and along the Mississippi andArkansas river systems.Of our 400 owned railcars, all are compliant with the standards for railcars built subsequent to 2011. Notwithstanding this, 131 of these ownedrailcars have been retrofitted to meet United States Department of Transportation (“DOT”) Specification 117 regulations (see “Railcar Regulation” below fora further discussion). Another 19 of these owned railcars are expected to be retrofitted by June 30, 2018. Of our 397 leased railcars, 310 are compliant with thestandards for railcars built subsequent to 2011 (see Part I, Item 1A–“Risk Factors).We contract for truck, rail, and barge transportation services from third parties and ship on 21 common carrier pipelines. We own 27 pipelineinjection stations, the locations of which are summarized below.State Number of Pipeline Injection StationsTexas 14Oklahoma 6New Mexico 5Kansas 2Total 27We also have commitments on several interstate pipelines for transportation of crude oil.We own eight storage terminal facilities. The largest of these is a terminal in Cushing, Oklahoma with a storage capacity of 3,600,000 barrels. Thecombined storage capacity of the other seven terminals is 1,479,400 barrels.We lease 1,080,000 barrels of capacity at two storage terminal facilities. Of this leased storage capacity, 950,000 barrels are at Cushing, Oklahoma.On December 22, 2017, we sold our previously held 50% interest in Glass Mountain. Glass Mountain is a 210-mile crude oil pipeline that originatesin western Oklahoma and terminates in Cushing, Oklahoma. This pipeline, which became operational in February 2014, has a capacity of 147,000 barrels perday.Customers. Our customers include crude oil refiners, producers, and marketers. During the year ended March 31, 2018, 66% of the revenues of ourCrude Oil Logistics segment were generated from our ten largest customers of the segment. In addition to utilizing our assets to transport crude oil we own,we also provide truck transportation, barge transportation, storage, and terminal throughput services to our customers.Competition. Our Crude Oil Logistics business faces significant competition, as many entities are engaged in the crude oil logistics business, someof which are larger and have greater financial resources than we do. The primary factors on which we compete are:•price;•availability of supply;•reliability of service;•logistics capabilities, including the availability of railcars, proprietary terminals, and owned pipelines, barges, railcars, trucks, and towboats;•long-term customer relationships; and•the acquisition of businesses.Supply. We obtain crude oil from a large base of suppliers, which consists primarily of crude oil producers. We currently purchase crude oil fromapproximately 200 producers at approximately 2,500 leases.Pricing Policy. Most of our contracts to purchase or sell crude oil are at floating prices that are indexed to published rates in active markets such asCushing, Oklahoma. We seek to manage price risk by entering into purchase and sale contracts11Table of Contentsof similar volumes based on similar indexes and by hedging exposure due to fluctuations in actual volumes and scheduled volumes.Our profitability is impacted by forward crude oil prices. Crude oil markets can either be in contango (a condition in which forward crude oil pricesare greater than spot prices) or can be backwardated (a condition in which forward crude oil prices are lower than spot prices). Our Crude Oil Logisticsbusiness benefits when the market is in contango, as increasing prices result in inventory holding gains during the time between when we purchase inventoryand when we sell it. In addition, we are able to better utilize our storage assets when contango markets justify storing barrels. When markets are backwardated,falling prices typically have an unfavorable impact on our margins.Billing and Collection Procedures. Our Crude Oil Logistics customers consist primarily of crude oil refiners, producers, and marketers. We typicallyinvoice these customers on a monthly basis. We perform credit analysis, require credit approvals, establish credit limits, and follow monitoring procedures onthese customers. We believe the following procedures enhance our collection efforts with these customers:•we require certain customers to prepay or place deposits for our services;•we require certain customers to post letters of credit or other forms of surety on a portion of our receivables; •we review receivable aging analyses regularly to identify issues or trends that may develop; and•we require our marketing personnel to manage their customers’ receivable position and suspend sales to customers that have not timely paidinvoices.Trade Names. Our Crude Oil Logistics segment operates primarily under the NGL Crude Logistics, NGL Crude Transportation and NGL Marine tradenames.Water SolutionsOverview. Our Water Solutions segment provides services for the treatment and disposal of wastewater generated from crude oil and natural gasproduction and for the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, ourWater Solutions segment sells the recovered hydrocarbons that result from performing these services. Our water processing facilities are strategically locatednear areas of high crude oil and natural gas production, including the Permian Basin in Texas and New Mexico, the DJ Basin in Colorado, the Eagle Fordshale play in Texas, the Bakken shale play in North Dakota, and the Pinedale Anticline in Wyoming. During the year ended March 31, 2018, we tookdelivery of 258.2 million barrels of wastewater, an average of 707,000 barrels per day.Our Water Solutions segment is in the process of expanding its solids disposal business. With the addition of specialized equipment to selectfacilities in the Eagle Ford shale play, the Permian Basin, and the DJ Basin, we are able to accept and dispose of solids such as tank bottoms, drilling fluidsand drilling muds generated by crude oil and natural gas exploration and production activities. Our facilities will accept only exploration and productionexempt waste allowed under our current permits.12Table of ContentsOperations. We own 75 water treatment and disposal facilities, including 100 wells. The location and permitted processing capacities of thesefacilities and whether the facilities are located on lands we own or lease are summarized below.

Our pipeline delivered volumes will continue to increase as new projects come on line. Once we take delivery of thewater, the level of processing is determined by the ultimate disposition of the water. Our solids customers bring solids generated by crude oil and natural gasexploration and production operations to our facilities by truck.Our facilities in Colorado, Texas, New Mexico and North Dakota dispose of wastewater primarily into deep underground formations via injectionwells.Our facility servicing the Pinedale Anticline in Wyoming has the assets and technology needed to treat the water more extensively than a typicaldisposal facility. At this facility, the water is recycled, rather than being disposed of in an injection well. We process the water to the point where it can bereturned to producers to be reused in future drilling operations (recycle quality water). Recycling offers producers an alternative to the use of fresh water inhydraulic fracturing operations. This minimizes the impact on aquifers, particularly in arid regions of the United States. We also previously treated the waterto a greater extent, such that it exceeded the standards for drinking water, and could be returned to the ecosystem (discharge quality water), which operationsceased during the third quarter of fiscal year 2018. Since June 2012, we have recycled approximately 18.5 million barrels (777 million gallons) of recyclequality water, have returned approximately 9.0 million barrels (378 million gallons) of discharge quality water back to New Fork River, which is a tributaryof the Colorado River, and have returned approximately 2.6 million barrels (109 million gallons) of water to the ecosystem through an agricultural irrigationsystem.At our disposal facilities, we use proprietary well maintenance programs to enhance injection rates and extend the service lives of the wells.Customers. The customers of our Wyoming and Colorado facilities consist primarily of large exploration and production companies that conductdrilling operations near our facilities. The customers of our Texas and North Dakota facilities consist of both wastewater transportation companies andproducers. The primary customer of our Wyoming facility has committed to deliver a specified minimum volume of water to our facility under a long-termcontract. The primary customers of our Colorado facilities have committed to deliver all wastewater produced at wells within the DJ Basin to our facilities.One customer in Texas has committed to deliver a minimum volume of 40,000 barrels of wastewater per day to our facilities. Most customers of our otherfacilities are not under volume commitments, although many of our facilities have acreage dedications or are connected to producer facilities by pipeline.During the year ended March 31, 2018, 16% of the water treatment and disposal revenues of our Water Solutions segment were generated from our two largestcustomers of the segment, and 47% of the water treatment and disposal revenues of the segment were generated from our ten largest customers of the segment.13Table of ContentsCompetition. We compete with other processors of wastewater to the extent that other processors have facilities geographically close to our facilities.Location is an important consideration for our customers, who seek to minimize the cost of transporting the wastewater to disposal facilities. Our facilities arestrategically located near areas of high crude oil and natural gas production. A significant factor affecting the profitability of our Water Solutions segment isthe extent of exploration and production in the areas near our facilities, which is generally based upon producers’ expectations about the profitability ofdrilling new wells.Pricing Policy. We generally charge customers a fee per barrel of wastewater processed. Certain contracts require the customer to deliver a specifiedminimum volume of wastewater over a specified period of time. We also generate revenue from the sale of hydrocarbons we recover in the process of treatingthe wastewater, which we take into consideration in negotiating the processing fees with our customers.Billing and Collection Procedures. Our Water Solutions customers consist of large exploration and production companies and also watertransportation companies. We typically invoice these customers on a monthly basis. We perform credit analysis, require credit approvals, establish creditlimits, and follow monitoring procedures on these customers. We believe the following procedures enhance our collection efforts with these customers:•we require certain customers to prepay or place deposits for our services;•we require certain customers to post letters of credit or other forms of surety on a portion of our receivables;•we review receivable aging analyses regularly to identify issues or trends that may develop; and•we require our marketing personnel to manage their customers’ receivable position and suspend service to customers that have not timely paidinvoices.Trade Names. Our Water Solutions segment operates primarily under the NGL Water Solutions and Anticline Disposal trade names.Technology. We hold multiple patents for processing technologies. We believe that the technological capabilities of our Water Solutions businesscan be quickly implemented at new facilities and locations.LiquidsOverview. Our Liquids segment provides natural gas liquids procurement, storage, transportation, and supply services to customers through assetsowned by us and third parties. Our Liquids business supplies the majority of the propane for our Retail Propane business as well as other retail propanebusinesses. We also sell butanes and natural gasolines to refiners and producers for use as blending stocks and diluent and assist refineries by managing theirseasonal butane supply needs. During the year ended March 31, 2018, we sold 2.3 billion gallons of natural gas liquids, an average of 6.32 million gallonsper day.Operations. We procure natural gas liquids from refiners, gas processing plants, producers and other resellers for delivery to leased or owned storagespace, common carrier pipelines, railcar terminals, and direct to certain customers. Our customers take delivery by loading natural gas liquids into transportvehicles from common carrier pipeline terminals, private terminals, our terminals, directly from refineries and rail terminals, and by railcar.A portion of our wholesale propane gallons are presold to third-party retailers and wholesalers at a fixed price under back-to-back contracts. Back-to-back contracts, in which we balance our contractual portfolio by buying physical propane supply or derivatives when we have a matching purchasecommitment from our wholesale customers, protect our margins and mitigate commodity price risk. Presales also reduce the impact of warm weather becausethe customer is required to take delivery of the propane regardless of the weather or any other factors. We generally require cash deposits from thesecustomers. In addition, on a daily basis we have the ability to balance our inventory by buying or selling propane, butanes, and natural gasoline to refiners,resellers, and propane producers through pipeline inventory transfers at major storage hubs.In order to secure consistent supply during the heating season, we are often required to purchase volumes of propane during the entire fiscal year. Inorder to mitigate storage costs and price risk, we may sell those volumes at a lesser margin than we earn in our other wholesale operations.We purchase butane from refiners during the summer months, when refiners have a greater butane supply than they need, and sell butane to refinersduring the winter blending season, when demand for butane is higher. We utilize a portion of our railcar fleet and a portion of our leased underground storageto store butane for this purpose.14Table of ContentsWe also transport customer-owned natural gas liquids on our leased railcars and charge the customers a transportation service fee as well assubleasing railcars to certain customers.We own 21 natural gas liquids terminals and we lease a fleet of approximately 4,500 high-pressure and general purpose railcars (of which 175railcars are subleased to third parties). These assets give us the opportunity to access wholesale markets throughout the United States, and to move product tolocations where demand is highest. We utilize these terminals and railcars primarily in the service of our wholesale propane, butane and asphalt operations,although we also provide transportation, storage, and throughput services to other parties to a lesser extent.The location of the facilities and their throughput capacity are summarized below.Facility Throughput Capacity(gallons per day) Terminal InterconnectsArkansas 2,226,800 Connected to Enterprise Texas Eastern Products Pipeline; Rail FacilityMissouri 1,813,000 Connected to Phillips66 Blue Line PipelineMinnesota 1,441,000 Connected to Enterprise Mid-America Pipeline; Rail FacilityIndiana 1,058,000 Connected to Enterprise Texas Eastern Products Pipeline; Rail FacilityIllinois 883,000 Connected to Phillips66 Blue Line PipelineWisconsin 863,000 Connected to Enterprise Mid-America Pipeline; Rail FacilityWashington 717,000 Rail FacilityLouisiana 600,000 Truck FacilityOklahoma 600,000 Connected to Phillips66 Chisholm Pipeline; Rail FacilityMassachusetts 441,000 Rail FacilityNew Mexico 408,000 Rail FacilityMontana 120,000 Rail FacilityUnited States Total 11,170,800 Ontario, Canada 700,000 Truck FacilityCanada Total 700,000 Total 11,870,800 We have operating agreements with third parties for certain of our terminals. The terminals in East St. Louis, Illinois and Jefferson City, Missouri areoperated for us by a third party for a monthly fee under an operating and maintenance agreement that expires in November 2022. The terminal in St.Catherines, Ontario, Canada is operated by a third party under a year-to-year agreement.We own the land on which 14 of the 21 natural gas liquids terminals are located and we either have easements or lease the land on which theremaining terminals are located. The terminals in East St. Louis, Illinois and Jefferson City, Missouri have perpetual easements, and the terminal in St.Catherines, Ontario, Canada has a long-term lease that expires in 2022.We are the majority owner of an underground storage facility near Delta, Utah. This facility currently has capacity to store approximately 6.0 millionbarrels of natural gas liquids and refined products. We lease storage to approximately 16 customers, with lease terms ranging from one to three years. Thefacility is located on property for which we have a long-term lease.We own a natural gas liquids terminal that supports refined products blending in Port Hudson, Louisiana, and a natural gas liquids and condensatefacility in Kingfisher, Oklahoma. The Port Hudson Terminal is located near Baton Rouge, Louisiana, and is in proximity to other refined productsinfrastructure along the Colonial pipeline. This truck unloading and storage facility allows for the aggregation and supply of butane and naphtha for motorfuel blending and consists of storage tanks with total capacity of 720,000 gallons. The Kingfisher Facility is a natural gas liquids and condensate facilitylocated in Kingfisher, Oklahoma, which is located in the middle of the STACK production region. The facility connects to the Chisholm NGL pipeline andthe Conway Fractionation complex and consists of 450,000 gallons of storage capacity, a methanol extraction tower and a 5,000-barrel per day condensatesplitter.15Table of ContentsWe own 23 transloading units, which enable customers to transfer product from railcars to trucks. These transloading units can be moved tolocations along a railroad where it is most convenient for customers to transfer their product.We lease natural gas liquids storage space to accommodate the supply requirements and contractual needs of our retail and wholesale customers. Welease storage space for natural gas liquids in various storage hubs in Kansas, Mississippi, Missouri, Texas and Canada.The following table summarizes our significant leased storage space at natural gas liquids storage facilities and interconnects to those facilities: Leased Storage Space(gallons) Storage Facility BeginningApril 1,2018 AtMarch 31,2018 Storage InterconnectsKansas 67,200,000 75,390,000 Connected to Enterprise Mid-America, NuStar Pipelines and ONEOK NorthSystem Pipeline; Rail Facility; Truck FacilityMississippi 9,660,000 7,560,000 Connected to Enterprise Dixie Pipeline; Rail FacilityMissouri 7,560,000 7,560,000 Truck FacilityTexas 6,510,000 50,400,000 Connected to Enterprise Texas Eastern Products Pipeline; Truck FacilityLouisiana — 6,300,000 Connected to Enlink Pipe; Rail FacilityIndiana — 210,000 Connected to Enterprise Texas Eastern Products Pipeline; Rail FacilityUnited States Total 90,930,000 147,420,000 Ontario, Canada 23,179,000 23,179,000 Rail FacilityAlberta, Canada 3,441,000 5,162,000 Connected to Cochin Pipeline; Rail FacilityCanada Total 26,620,000 28,341,000 Total 117,550,000 175,761,000 Customers. Our Liquids business serves approximately 900 customers in 48 states. Our Liquids business serves national, regional and independentretail, industrial, wholesale, petrochemical, refiner and natural gas liquids production customers. Our Liquids business also supplies the majority of thepropane for our Retail Propane business. We deliver the propane supply to our customers at terminals located on common carrier pipelines, rail terminals,refineries, and major United States propane storage hubs. During the year ended March 31, 2018, 27% of the revenues of our Liquids segment were generatedfrom our ten largest customers of the segment (exclusive of sales to our Retail Propane segment).Seasonality. Our wholesale Liquids business is affected by the weather in a similar manner as our Retail Propane business as discussed below.However, we are able to partially mitigate the effects of seasonality by preselling a portion of our wholesale volumes to retailers and wholesalers andrequiring the customer to take delivery of the product regardless of the weather.Competition. Our Liquids business faces significant competition, as many entities, including other natural gas liquids wholesalers and companiesinvolved in the natural gas liquids midstream industry (such as terminal and refinery operations), are engaged in the liquids business, some of which havegreater financial resources than we do. The primary factors on which we compete are:•price;•availability of supply;•reliability of service;•available space on common carrier pipelines;•storage availability;•logistics capabilities, including the availability of railcars, and proprietary terminals;16Table of Contents•long-term customer relationships; and•the acquisition of businesses.Pricing Policy. In our Liquids business, we offer our customers three categories of contracts for propane sourced from common carrier pipelines:•customer pre-buys, which typically require deposits based on market pricing conditions;•market based, which can either be a posted price or an index to spot price at time of delivery; and•load package, a firm price agreement for customers seeking to purchase specific volumes delivered during a specific time period.We use back-to-back contracts for many of our Liquids segment sales to limit exposure to commodity price risk and protect our margins. We are ableto match our supply and sales commitments by offering our customers purchase contracts with flexible price, location, storage, and ratable delivery. However,certain common carrier pipelines require us to keep minimum in-line inventory balances year round to conduct our daily business, and these volumes are notmatched with a sales commitment.We generally require deposits from our customers for fixed price future delivery of propane if the delivery date is more than 30 days after the time ofcontractual agreement.Billing and Collection Procedures. Our Liquids segment customers consist of commercial accounts varying in size from local independentdistributors to large regional and national retailers. These sales tend to be large volume transactions that can range from 10,000 gallons up to 1,000,000gallons, and deliveries can occur over time periods extending from days to as long as a year. We perform credit analysis, require credit approvals, establishcredit limits, and follow monitoring procedures on these customers. We believe the following procedures enhance our collection efforts with these customers:•we require certain customers to prepay or place deposits for their purchases;•we require certain customers to post letters of credit or other forms of surety on a portion of our receivables;•we require certain customers to take delivery of their contracted volume ratably to help control the account balance rather than allowing them totake delivery of propane at their discretion;•we review receivable aging analysis regularly to identify issues or trends that may develop; and•we require our marketing personnel to manage their customers’ receivable position and suspend sales to customers that have not timely paidinvoices.Trade Names. Our Liquids segment operates primarily under the NGL Supply Wholesale, NGL Supply Terminal Company, Sawtooth Caverns,Centennial Energy, and Centennial Gas Liquids trade names.Retail PropaneOverview. Our Retail Propane segment consists of the retail marketing, sale and distribution of propane and distillates, including the sale and leaseof propane tanks, equipment and supplies, to more than 320,000 residential, agricultural, commercial and industrial customers. We also sell propane tocertain resellers. We purchase the majority of the propane sold in our Retail Propane business from our Liquids business, which provides our Retail Propanebusiness with a stable and secure supply of propane. During the year ended March 31, 2018, we sold 234.6 million gallons of propane and distillates, anaverage of 643,000 gallons per day. On March 30, 2018, we sold a portion of our Retail Propane segment (see “Dispositions” above), which accounted for67.8 million gallons, or 29%, of propane sold during the year ended March 31, 2018.Operations. We market retail propane and distillates through our customer service locations. We sell propane primarily in rural areas, but we alsohave a number of customers in suburban areas where energy alternatives to propane such as natural gas are not generally available. We own or lease 91customer service locations and 72 satellite distribution locations, with aggregate propane storage capacity of 13.0 million gallons and aggregate distillatestorage capacity of 5.7 million gallons. Our customer service locations are staffed and operated to service a defined geographic market area and typicallyinclude a business office, product showroom, and secondary propane storage. Our satellite distribution locations, which are unmanned storage tanks, allowour customer service centers to serve an extended market area.17Table of ContentsThe following table summarizes the number of our customer service locations and satellite distribution locations by state:State Number of CustomerService Locations Number of SatelliteDistribution LocationsGeorgia 27 11Massachusetts 14 10North Carolina 13 15Maine 11 10Pennsylvania 9 5New Hampshire 6 7Connecticut 3 3South Carolina 2 2Alabama 1 1Florida 1 —Maryland 1 1New Jersey 1 2Rhode Island 1 1Tennessee 1 1Vermont — 3Total 91 72 We own 57 of our 91 customer service locations and 36 of our 72 satellite distribution locations, and we lease the remainder.Tank ownership at customer locations is an important component to our operations and customer retention. At March 31, 2018, we owned thefollowing propane storage tanks:•over 300 bulk storage tanks with capacities ranging from 18,000 to 90,000 gallons; and•over 350,000 stationary customer storage tanks with capacities ranging from 7 to 30,000 gallons.We also lease an additional 16 bulk storage tanks ranging from 5,000 to 61,500 gallons.At March 31, 2018, we owned a fleet of 480 bulk delivery trucks, 30 semi-tractors, 30 propane transport trailers and 475 other service trucks.Retail deliveries of propane are usually made to customers by means of our fleet of bulk delivery trucks. Propane is pumped from the bulk deliverytruck, which holds from 2,200 to 5,000 gallons, into a storage tank at the customer’s premises. The capacity of these storage tanks ranges from 50 to 30,000gallons. We also deliver propane to retail customers in portable cylinders, which typically have a capacity of 5 to 25 gallons. These cylinders are eitherpicked up on a delivery route, refilled at our customer service locations, and then returned to the retail customer, or refilled at the customer’s location.Customers can also bring the cylinders to our customer service centers to be refilled.Approximately 72% of our residential customers receive their propane supply via our automatic route delivery program, which allows us tomaximize our delivery efficiency. For these customers, our delivery forecasting software system utilizes a customer’s historical consumption patternscombined with current weather conditions to more accurately predict the optimal time to refill the customer’s tank. The delivery information is then uploadedto routing software to calculate the most cost effective delivery route. Our automatic delivery program promotes customer retention by providing anuninterrupted supply of propane and enables us to efficiently conduct route deliveries on a regular basis. Some of our purchase plans, such as level paymentbilling, fixed price, and price cap programs, further promote our automatic delivery program.18Table of ContentsCustomers. Our retail propane and distillate customers fall into three broad categories: residential, commercial and industrial, and agricultural. AtMarch 31, 2018, our retail propane and distillate customers were comprised of:•68% residential customers;•31% commercial and industrial customers; and•1% agricultural customers.No single customer accounted for more than 1% of our retail propane volumes during the year ended March 31, 2018.Seasonality. The retail propane and distillate business is largely seasonal due to the primary use of propane and distillates as heating fuels. Inparticular, residential and agricultural customers who use propane and distillates to heat homes and livestock buildings generally only need to purchasepropane during the typical fall and winter heating season. Propane sales to agricultural customers who use propane for crop drying are also seasonal, althoughthe impact on our retail propane volumes sold varies from year to year depending on the moisture content of the crop and the ambient temperature at the timeof harvest. Propane and distillate sales to commercial and industrial customers, while affected by economic patterns, are not as seasonal as sales to residentialand agricultural customers.Competition. Our Retail Propane business faces significant competition, as many entities are engaged in the retail propane business, some of whichhave greater financial resources than we do. Also, we compete with alternative energy sources, including natural gas and electricity. The primary factors onwhich we compete are:•price;•availability of supply;•reliability of service;•long-term customer relationships; and•the acquisition of businesses.Competition with other retail propane distributors in the propane industry is highly fragmented and generally occurs on a local basis with otherlarge full-service, multi-state propane marketers, smaller local independent marketers, and farm cooperatives. Our customer service locations generally haveone to five competitors in their market area.The competitive landscape of the markets that we serve has been fairly stable. Each customer service location operates in its own competitiveenvironment, since retailers are located in close proximity to their customers due to delivery economics. Our customer service locations generally have aneffective marketing radius of 25 to 55 miles, although in certain areas the marketing radius may be extended by satellite distribution locations.The ability to compete effectively depends on the ability to provide superior customer service, which includes reliability of supply, qualityequipment, well-trained service staff, efficient delivery, 24-hours-a-day service for emergency repairs and deliveries, multiple payment and purchase optionsand the ability to maintain competitive prices. Additionally, we believe that our safety programs, policies and procedures are more comprehensive than manyof our smaller, independent competitors, which offers a higher level of service to our customers. We also believe that our overall service capabilities andcustomer responsiveness differentiate us from many of our competitors.Supply. Our Retail Propane segment purchases the majority of its propane from our Liquids segment.Pricing Policy. Our pricing policy is an essential element in the successful marketing of retail propane and distillates. We protect our margin byadjusting our retail propane pricing based on, among other things, prevailing supply costs, local market conditions, and input from management at ourcustomer service locations. We rely on our regional management to set prices based on these factors. Our regional managers are advised regularly of anychanges in the delivered cost of propane and distillates, potential supply disruptions, changes in industry inventory levels, and possible trends in the futurecost of propane and distillates. We believe the market intelligence provided by our Liquids segment, combined with our propane and distillate pricingmethods allows us to respond to changes in supply costs in a manner that protects our customer base and our margins.19Table of ContentsBilling and Collection Procedures. In our Retail Propane business, our customer service locations are typically responsible for customer billing andaccount collection. We believe that this decentralized and more personal approach is beneficial because our local staff has more detailed knowledge of ourcustomers, their needs, and their history than would an employee at a remote billing center. Our local staff often develops relationships with our customersthat are beneficial in reducing payment time for a number of reasons:•customers are billed on a timely basis;•customers tend to keep accounts receivable balances current when paying a local business and people they know;•many customers prefer the convenience of paying in person; and•billing issues may be handled more quickly because local personnel have current account information and detailed customer history availableto them at all times to answer customer inquiries.Our Retail Propane customers must comply with our standards for extending credit, which typically includes submitting a credit application,supplying credit references, and undergoing a credit check with an appropriate credit agency.Trade Names. We use a variety of trademarks and trade names that we own, including Anthem Propane Exchange, Brantley Gas, Coastal Energy,Downeast Energy, Eastern Propane, Gas Inc., Lumber River Propane, Osterman Propane, Proflame, Stallings Propane, Stiles Fuels, Stokes & Congleton,Carolina Energies, Triad Propane, Woodstock Gas, Yadkin Propane and Propane Services, among others. We typically retain and continue to use the names ofthe companies that we acquire and believe that this helps maintain the local identification of these companies and contributes to their continued success. Weregard our trademarks, trade names, and other proprietary rights as valuable assets and believe that they have significant value in the marketing of ourproducts.Refined Products and RenewablesOverview. Our Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations. In addition, incertain storage locations, our Refined Products and Renewables segment may also purchase unfinished gasoline blending components for subsequentblending into finished gasoline to supply our marketing business as well as third parties. During the year ended March 31, 2018, we sold 108.4 millionbarrels of gasoline, 56.0 million barrels of diesel, 3.4 million barrels of ethanol and 2.1 million barrels of biodiesel.Operations. The refined products we handle include gasoline, diesel, and heating oil. We purchase refined petroleum and renewable productsprimarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedule them for delivery at various locations throughout the country.On certain interstate refined products pipelines, shipment demand exceeds available capacity, and capacity is allocated to shippers based on their historicalshipment volumes. We hold allocated capacity on the Colonial and Plantation pipelines.A significant percentage of our business is priced on a back-to-back basis which minimizes our commodity price exposure. We sell our products tocommercial and industrial end users, independent retailers, distributors, marketers, government entities, and other wholesalers of refined petroleum products.We sell our products at terminals owned by third parties. As discussed in “Dispositions” above, on February 1, 2016, we sold our general partner interest inTLP. As a result, on February 1, 2016, we deconsolidated TLP and began to account for our limited partner investment in TLP using the equity method ofaccounting. As part of this transaction, we retained TransMontaigne Product Services LLC, including its marketing business, customer contracts and its linespace on the Colonial and Plantation pipelines, which is a significant part of our Refined Products and Renewables segment. We also entered into leaseagreements whereby we will remain the long-term exclusive tenant in the TLP Southeast terminal system.20Table of ContentsThe following table summarizes our leased storage space at refined products storage facilities:Locations Active Storage Capacity(shell barrels)Southeast Facilities Virginia 2,791,000Georgia 1,963,000Mississippi 1,588,516New Jersey 1,155,000North Carolina 775,000Alabama 178,000South Carolina 166,000Louisiana 100,000Florida 62,000Total Southeast Facilities Storage Capacity (1) 8,778,516 Mid-Continent Facilities Magellan North system 830,000NuStar East Products system 240,000Total Mid-Continent Facilities Storage Capacity 1,070,000 West Facilities Kinder Morgan (Phoenix, Arizona) 50,000 Total Facilities Storage Capacity 9,898,516 (1)Includes 1,067,900 barrels of capacity that is subleased to third parties.We purchase ethanol primarily at production facilities in the Midwest and transport the ethanol via trucks and railcars for sale at various locations.We also blend ethanol into gasoline for sale to customers at third party terminals. We market and handle logistics for third-party ethanol manufacturers for aservice fee. We primarily purchase biodiesel from production facilities in the Midwest and in Houston, Texas, and transport the biodiesel via railcar to sell tocustomers. We lease a total of 12,000 barrels of biodiesel storage in Deer Park, Texas and have a biodiesel terminaling agreement at a fuel terminal inPhoenix, Arizona with a minimum monthly throughput requirement. We lease 346 railcars for the transportation of renewables, of which 299 railcars aresubleased to a third party.Customers. Our Refined Products and Renewables segment serves customers in 38 states. During the year ended March 31, 2018, 35% of therevenues of our Refined Products and Renewables segment were generated from our ten largest customers of the segment. We sell to customers via rack spotsales, contract sales, bulk sales, and just-in-time sales.Contract sales are made pursuant to negotiated contracts, generally ranging from one to twelve months in duration, that we enter into with localmarket wholesalers, independent gasoline station chains, heating oil suppliers, and other customers. Contract sales provide these customers with a specifiedvolume of product during the term of the agreement. Delivery of product sold under these arrangements generally is at third party truck racks. The pricing ofthe product delivered under a majority of our contract sales is based on published index prices, and varies based on changes in the applicable indices. Inaddition, at the customer’s option, the contract price may be fixed at a stipulated price per gallon.Rack spot sales are sales that do not involve continuing contractual obligations to purchase or deliver product. Rack spot sales are priced anddelivered on a daily basis through truck loading racks. At the end of each day for each of the terminals that we market from, we establish the next day sellingprice for each product for each of our delivery locations. We announce or “post” to customers via website, e-mail, and telephone communications the rackspot sale price of various products for the following morning. Typical rack spot sale purchasers include commercial and industrial end users, independentretailers and small, independent marketers who resell product to retail gasoline stations or other end users. Our selling price of a particular product on aparticular day is a function of our supply at that delivery location or terminal, our estimate of the costs to replenish the product at that delivery location, andour desire to reduce inventory levels at that particular location that day.21Table of ContentsBulk sales generally involve the sale of products in large quantities in the major cash markets including the Houston Gulf Coast and New YorkHarbor. A bulk sale of products also may be made while the product is being transported on common carrier pipelines.We conduct just-in-time sales at a nationwide network of terminals owned by third parties. We post prices at each of these locations on a daily basis.When customers decide to purchase product from us, we purchase the same volume of product from a supplier at a previously agreed-upon price. For thesejust-in-time transactions, our purchase from the supplier occurs at the same time as our sale to our customer.Seasonality. The demand for gasoline typically peaks during the summer driving season, which extends from April to September, and declinesduring the fall and winter months. However, the demand for diesel typically peaks during the fall and winter months due to colder temperatures in theMidwest and Northeast.Competition. Our Refined Products and Renewables business faces significant competition, as many entities are engaged in the refined products andrenewables business, some of which have greater financial resources than we do. The primary factors on which we compete are:•price;•availability of supply;•reliability of service;•available space on common carrier pipelines;•storage availability;•logistics capabilities, including the availability of railcars, and proprietary terminals; and•long-term customer relationships.Market Price Risk. Our philosophy is to maintain minimum commodity price exposure through a combination of purchase contracts, sales contractsand financial derivatives. A significant percentage of our business is priced on a back-to-back basis which minimizes our commodity price exposure. Fordiscretionary inventory, and for those instances where physical transactions cannot be appropriately matched, we utilize financial derivatives to mitigatecommodity price exposure. Specific exposure limits are mandated in our credit agreement and in our market risk policy.The value of refined products in any local delivery market is the sum of the commodity price as reflected on the NYMEX and the basis differentialfor that local delivery market. The basis differential for any local delivery market is the spread between the cash price in the physical market and the quotedprice in the futures markets for the prompt month. We typically utilize NYMEX futures contracts to mitigate commodity price exposure. We generally do notmanage the financial impact on us from changes in basis differentials affected by local market supply and demand disruptions.Legal and Regulatory Considerations. Demand for ethanol and biodiesel is driven in large part by government mandates and incentives. Refinersand producers are required to blend a certain percentage of renewables into their refined products, although the percentage can vary from year to year basedon the United States Environmental Protection Agency (“EPA”) mandates. In addition, the federal government has in recent years granted certain tax creditsfor the use of biodiesel, although on several occasions these tax credits have expired. In February 2018, the federal government passed a law to reinstate thetax credit retroactively to January 1, 2017, with the credit expiring on December 31, 2017. Changes in future mandates and incentives, or decisions by thefederal government related to future reinstatement of the biodiesel tax credit, could result in changes in demand for ethanol and biodiesel.Billing and Collection Procedures. Our Refined Products and Renewables customers consist primarily of commercial and industrial end users,independent retailers, distributors, marketers, government entities, and other wholesalers of refined petroleum products. We perform credit analysis, requirecredit approvals, establish credit limits, and follow monitoring procedures on our Refined Products and Renewables customers. We believe the followingprocedures enhance our collection efforts with our customers:•we require certain customers to prepay or place deposits for our services;•we require certain customers to post letters of credit or other forms of surety on a portion of our receivables;22Table of Contents•we monitor individual customer receivables relative to previously-approved credit limits, and our automated rack delivery system gives us theoption to discontinue providing product to customers when they exceed their credit limits;•we review receivable aging analyses regularly to identify issues or trends that may develop; and•we require our marketing personnel to manage their customers’ receivable position and suspend sales to customers that have not timely paidinvoices.Trade Names. Our Refined Products and Renewables segment operates primarily under the NGL Crude Logistics and TransMontaigne ProductServices LLC trade names.EmployeesAt March 31, 2018, we had approximately 2,400 full-time employees. Thirty eight of our employees at three of our locations are members of a laborunion. We believe that our relations with our employees are satisfactory.Government RegulationRegulation of the Oil and Natural Gas IndustriesRegulation of Oil and Natural Gas Exploration, Production and Sales. Sales of crude oil and natural gas liquids are not currently regulated and aretransacted at market prices. In 1989, the United States Congress enacted the Natural Gas Wellhead Decontrol Act, which removed all remaining price andnon-price controls affecting wellhead sales of natural gas. The Federal Energy Regulatory Commission (“FERC”), which has authority under the Natural GasAct to regulate the prices and other terms and conditions of the sale of natural gas for resale in interstate commerce, has issued blanket authorizations for allnatural gas resellers subject to its regulation, except interstate pipelines, to resell natural gas at market prices. Either Congress or the FERC (with respect tothe resale of natural gas in interstate commerce), however, could re-impose price controls in the future.Exploration and production operations are subject to various types of federal, state and local regulation, including, but not limited to, permitting,well location, methods of drilling, well operations, and conservation of resources. While these regulations do not directly apply to our business, they mayaffect the businesses of certain of our customers and suppliers and thereby indirectly affect our business.Regulation of the Transportation and Storage of Natural Gas and Oil and Related Facilities. The FERC regulates oil pipelines under the InterstateCommerce Act and natural gas pipeline and storage companies under the Natural Gas Act, and Natural Gas Policy Act of 1978 (the “NGPA”), as amended bythe Energy Policy Act of 2005. The Grand Mesa Pipeline became operational on November 1, 2016 and has several points of origin in Colorado, runs fromthose origin points through Kansas and terminates in Cushing, Oklahoma. The transportation services on the Grand Mesa Pipeline are subject to FERCregulation. In February 2018, the FERC issued a revised policy to disallow income tax allowance cost recovery in rates charged by pipeline companiesorganized as master limited partnerships. The FERC’s revised policy impacts cost-of-service rates on oil pipelines. Currently, the volumes of crude oil that aretransported on the Grand Mesa Pipeline are subject to contractual agreements. Therefore, the FERC’s revised policy is not expected to impact the Grand MesaPipeline at the present time. Additionally, contracts we enter into for the interstate transportation or storage of crude oil or natural gas may be subject toFERC regulation including reporting or other requirements. In addition, the intrastate transportation and storage of crude oil and natural gas is subject toregulation by the state in which such facilities are located, and such regulation can affect the availability and price of our supply, and have both a direct andindirect effect on our business.Anti-Market Manipulation. We are subject to the anti-market manipulation provisions in the Natural Gas Act and the NGPA, which authorizes theFERC to impose fines of up to $1 million per day per violation of the Natural Gas Act, the NGPA, or their implementing regulations. In addition, the FederalTrade Commission (“FTC”) holds statutory authority under the Energy Independence and Security Act of 2007 to prevent market manipulation in petroleummarkets, including the authority to request that a court impose fines of up to $1 million per violation. These agencies have promulgated broad rules andregulations prohibiting fraud and manipulation in oil and gas markets. The Commodity Futures Trading Commission (“CFTC”) is directed under theCommodity Exchange Act to prevent price manipulations in the commodity and futures markets, including the energy futures markets. Pursuant to statutoryauthority, the CFTC has adopted anti-market manipulation regulations that prohibit fraud and price manipulation in the commodity and futures markets. TheCFTC also has statutory authority to seek civil penalties of up to the greater of $1 million per day per violation or triple the monetary gain to the violator forviolations of the anti-market23Table of Contentsmanipulation sections of the Commodity Exchange Act. We are also subject to various reporting requirements that are designed to facilitate transparency andprevent market manipulation.Maritime Transportation. The Jones Act is a federal law that restricts maritime transportation between locations in the United States to vessels builtand registered in the United States and owned and manned by United States citizens. Since we engage in maritime transportation through our barge fleetbetween locations in the United States, we are subject to the provisions of the law. As a result, we are responsible for monitoring the ownership of oursubsidiaries that engage in maritime transportation and for taking any remedial action necessary to ensure that no violation of the Jones Act ownershiprestrictions occurs. The Jones Act also requires that all United States-flagged vessels be manned by United States citizens. Foreign-flagged seamen generallyreceive lower wages and benefits than those received by United States citizen seamen. This requirement significantly increases operating costs of UnitedStates-flagged vessel operations compared to foreign-flagged vessel operations. Certain foreign governments subsidize their nations’ shipyards. This resultsin lower shipyard costs both for new vessels and repairs than those paid by United States-flagged vessel owners. The United States Coast Guard and AmericanBureau of Shipping maintain the most stringent regimen of vessel inspection in the world, which tends to result in higher regulatory compliance costs forUnited States-flagged operators than for owners of vessels registered under foreign flags of convenience.Environmental RegulationGeneral. Our operations are subject to stringent and complex federal, state and local laws and regulations relating to the protection of theenvironment. Accordingly, we must comply with these laws and regulations at the federal, state and local levels. These laws and regulations can restrict orimpact our business activities in many ways, such as:•requiring the installation of pollution-control equipment or otherwise restricting the way we operate or imposing additional costs on ouroperations;•limiting or prohibiting construction activities in sensitive areas, such as wetlands, coastal regions or areas inhabited by endangered orthreatened species;•delaying construction or system modification or upgrades during permit issuance or renewal;•requiring investigatory and remedial actions to mitigate pollution conditions caused by our operations or attributable to former operations; and•enjoining the operations of facilities deemed to be in non-compliance with permits or permit requirements issued pursuant to or imposed bysuch environmental laws and regulations.Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including theassessment of monetary penalties. Certain environmental statutes impose strict, joint and several liability for costs required to clean up and restore sites wheresubstances such as hydrocarbons or wastes have been disposed or otherwise released. The trend in environmental regulation is to place more restrictions andlimitations on activities that may adversely affect the environment. Thus, there can be no assurance as to the amount or timing of future expenditures forenvironmental compliance or remediation and actual future expenditures may be different from the amounts we currently anticipate.The following is a discussion of the material environmental laws and regulations that relate to our business.Hazardous Substances and Waste. We are subject to various federal, state, and local environmental laws and regulations governing the storage,distribution and transportation of natural gas liquids and the operation of bulk storage liquefied petroleum gas (LPG) terminals, as well as laws andregulations governing environmental protection, including those addressing the discharge of materials into the environment or otherwise relating toprotection of the environment. Generally, these laws (i) regulate air and water quality and impose limitations on the discharge of pollutants and establishstandards for the handling of solid and hazardous wastes; (ii) subject our operations to certain permitting and registration requirements; (iii) may result in thesuspension or revocation of necessary permits, licenses and authorizations; (iv) impose substantial liabilities on us for pollution resulting from ouroperations; (v) require remedial measures to mitigate pollution from former or ongoing operations; and (vi) may result in the assessment of administrative,civil and criminal penalties for failure to comply with such laws. These laws include, among others, the Resource Conservation and Recovery Act (“RCRA”),the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), the federal Clean Air Act, the Homeland Security Act of 2002,the Emergency Planning and Community Right to Know Act, the Clean Water Act, the Safe Drinking Water Act, and comparable state statutes. For example,as a flammable substance, propane is subject to risk management plan requirements under section 112(r) of the federal Clean Air Act.24Table of ContentsCERCLA, also known as the “Superfund” law, and similar state laws impose liability, without regard to fault or the legality of the original conduct,on certain classes of potentially responsible persons that are considered to have contributed to the release of a “hazardous substance” into the environment.These persons include the current and past owner or operator of the site where the release occurred, and anyone who disposed or arranged for the disposal of ahazardous substance released at the site. While natural gas liquids are not a hazardous substance within the meaning of CERCLA, other chemicals used in orgenerated by our operations may be classified as hazardous. Persons who are or were responsible for releases of hazardous substances under CERCLA may besubject to strict and joint and several liability for the costs of investigating and cleaning up the hazardous substances that have been released into theenvironment, for damages to natural resources and for the costs of certain health studies, and it is not uncommon for neighboring landowners and other thirdparties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment.RCRA, and comparable state statutes and their implementing regulations, regulate the generation, transportation, treatment, storage, disposal andcleanup of hazardous and non-hazardous wastes. Under the auspices of the EPA, most states administer some or all of the provisions of RCRA, sometimes inconjunction with their own, more stringent requirements. Federal and state regulatory agencies can seek to impose administrative, civil and criminal penaltiesfor alleged non-compliance with RCRA and analogous state requirements. Certain wastes associated with the production of oil and natural gas, as well ascertain types of petroleum-contaminated media and debris, are excluded from regulation as hazardous waste under Subtitle C of RCRA. These wastes, instead,are regulated under RCRA’s less stringent solid waste provisions, state laws or other federal laws. It is possible, however, that certain wastes now classified asnon-hazardous could be classified as hazardous wastes in the future and therefore be subject to more rigorous and costly disposal requirements. Legislationhas been proposed from time to time in Congress to re-categorize certain oil and natural gas wastes as “hazardous wastes.” Any such change could result in anincrease in our costs to manage and dispose of wastes, which could have a material adverse effect on our consolidated results of operations and financialposition.We currently own or lease properties where hydrocarbons are being or have been handled for many years. Although previous operators have utilizedoperating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on orunder the properties owned or leased by us or on or under the other locations where these hydrocarbons and wastes have been transported for treatment ordisposal. These properties and the wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, we could berequired to remove or remediate previously disposed wastes (including wastes disposed of or released by prior owners or operators), to clean up contaminatedproperty (including contaminated groundwater) or to implement remedial measures to prevent or mitigate future contamination. We are not currently aware ofany facts, events or conditions relating to such requirements that could materially impact our consolidated results of operations or financial position.Oil Pollution Prevention. Our operations involve the shipment of crude oil by barge through navigable waters of the United States. The OilPollution Prevention Act imposes liability for releases of crude oil from vessels or facilities into navigable waters. If a release of crude oil to navigable watersoccurred during shipment or from a terminal, we could be subject to liability under the Oil Pollution Prevention Act. We are not currently aware of any facts,events, or conditions related to oil spills that could materially impact our consolidated results of operations or financial position. In 1973, the EPA adoptedoil pollution prevention regulations under the Clean Water Act. These oil pollution prevention regulations, as amended several times since their originaladoption, require the preparation of a Spill Prevention Control and Countermeasure (“SPCC”) plan for facilities engaged in drilling, producing, gathering,storing, processing, refining, transferring, distributing, using, or consuming crude oil and oil products, and which due to their location, could reasonably beexpected to discharge oil in harmful quantities into or upon the navigable waters of the United States. The owner or operator of an SPCC-regulated facility isrequired to prepare a written, site-specific spill prevention plan, which details how a facility’s operations comply with the requirements. To be in compliance,the facility’s SPCC plan must satisfy all of the applicable requirements for drainage, bulk storage tanks, tank car and truck loading and unloading, transferoperations (intrafacility piping), inspections and records, security, and training. Most importantly, the facility must fully implement the SPCC plan and trainpersonnel in its execution. We maintain and implement such plans for our facilities.Air Emissions. Our operations are subject to the federal Clean Air Act and comparable state and local laws and regulations. These laws andregulations regulate emissions of air pollutants from various industrial sources, and also impose various monitoring and reporting requirements. Such lawsand regulations may require that we obtain permits prior to the construction or modification of certain projects or facilities expected to produce orsignificantly increase air emissions, obtain and strictly comply with air permits containing various emissions and operational limitations and utilize specificemission control technologies to limit emissions. Our failure to comply with these requirements could subject us to monetary penalties, injunctions,conditions or restrictions on operations and, potentially, criminal enforcement actions. Furthermore, we may be25Table of Contentsrequired to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operatingpermits and approvals for air emissions.Water Discharges. The Clean Water Act and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants intostate waters as well as waters of the United States and impose requirements affecting our ability to conduct construction activities in waters and wetlands.Certain state regulations and the general permits issued under the Federal National Pollutant Discharge Elimination System program prohibit the discharge ofpollutants and chemicals. SPCC requirements of federal laws require appropriate containment berms and similar structures to help prevent the contaminationof regulated waters in the event of a hydrocarbon or other constituent tank spill, rupture or leak. In addition, the Clean Water Act and analogous state lawsrequire individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. We have discharge permits inplace for a number of our facilities. These permits may require us to monitor and sample the storm water runoff from such facilities. Some states also maintaingroundwater protection programs that require permits for discharges or operations that may impact groundwater conditions. Federal and state regulatoryagencies can impose administrative, civil and criminal penalties for non-compliance with discharge permits or other requirements of the Clean Water Act andanalogous state laws and regulations.Underground Injection Control. Our underground injection operations are subject to the Safe Drinking Water Act, as well as analogous state lawsand regulations, which establish requirements for permitting, testing, monitoring, record keeping, and reporting of injection well activities, as well as aprohibition against the migration of fluid containing any contaminant into underground sources of drinking water. Any leakage from the subsurface portionsof the injection wells could cause degradation of fresh groundwater resources, potentially resulting in suspension of our permits, issuance of fines andpenalties from governmental agencies, incurrence of expenditures for remediation of the affected resource and imposition of liability by third parties forproperty damages and personal injuries.Hydraulic Fracturing. The underground injection of crude oil and natural gas wastes are regulated by the Underground Injection Control Programauthorized by the Safe Drinking Water Act. The primary objective of injection well operating requirements is to ensure the mechanical integrity of theinjection apparatus and to prevent migration of fluids from the injection zone into underground sources of drinking water. We do not conduct any hydraulicfracturing activities. However, a portion of our customers’ crude oil and natural gas production is developed from unconventional sources that requirehydraulic fracturing as part of the completion process and our Water Solutions business treats and disposes of wastewater generated from natural gasproduction, including production utilizing hydraulic fracturing. Hydraulic fracturing involves the injection of water, sand and chemicals under pressure intothe formation to stimulate oil and gas production. Legislation to amend the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing from thedefinition of underground injection and require federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to requiredisclosure of the chemical constituents of the fluids used in the fracturing process, have been proposed in recent sessions of Congress. Congress will likelycontinue to consider legislation to amend the Safe Drinking Water Act to subject hydraulic fracturing operations to regulation under the Act’s UndergroundInjection Control Program and/or to require disclosure of chemicals used in the hydraulic fracturing process. Federal agencies, including the EPA and theUnited States Department of the Interior, have asserted their regulatory authority to, for example, study the potential impacts of hydraulic fracturing on theenvironment, and initiate rulemakings to compel disclosure of the chemicals used in hydraulic fracturing operations, and establish pretreatment standards forwastewater from hydraulic fracturing operations. In addition, some states have also proposed or adopted legislative or regulatory restrictions on hydraulicfracturing, which include additional permit requirements, public disclosure of fracturing fluid contents, operational restrictions, and/or temporary orpermanent bans on hydraulic fracturing. We expect that scrutiny of hydraulic fracturing activities will continue in the future.Greenhouse Gas RegulationThere is a growing concern, both nationally and internationally, about climate change and the contribution of greenhouse gas emissions, mostnotably carbon dioxide, to global warming. For example, Sen. Charles Van Hollen, Jr. (D-MD) introduced the Healthy Climate and Family Security Act of2018 in the Senate on January 29, 2018 as S. 2352, and Rep. Donald Beyer (D-VA) introduced the same bill in the House of Representatives that same day asH.R. 4889. The bills would impose a cap on greenhouse gas emissions through requirement to purchase carbon permits and distribute the proceeds of suchpurchases to eligible individuals. The ultimate outcome of any possible future federal legislative initiatives is uncertain. In addition, several states havealready adopted some legal measures to reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emissioninventories and/or regional greenhouse gas cap-and-trade programs.On December 15, 2009, the EPA published its findings that emissions of carbon dioxide, methane and other greenhouse gases present anendangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth’satmosphere and other climatic changes. These findings allowed26Table of Contentsthe EPA to adopt and implement regulations to restrict emissions of greenhouse gases under existing provisions of the federal Clean Air Act. On May 12,2016, the EPA finalized three rules that regulate greenhouse gas emissions from certain sources in the oil and natural gas industry, which became effective onAugust 2, 2016. On April 18, 2017, the EPA announced its intention to reconsider certain aspects of these rules in response to several administrativereconsideration opinions. On June 12, 2017, the EPA issued a proposed rulemaking that would stay for two years with various requirements of the rule whilethe EPA reconsiders them. The schedule for when this rulemaking could be finalized is not presently known. The EPA’s greenhouse gas regulations couldrequire us to incur costs to reduce emissions of greenhouse gases associated with our operations and also could adversely affect demand for the products thatwe transport, store, process, or otherwise handle in connection with our services.Some scientists have suggested climate change from greenhouse gases could increase the severity of extreme weather, such as increased hurricanesand floods, which could damage our facilities. Another possible consequence of climate change is increased volatility in seasonal temperatures. The marketfor our natural gas liquids is generally improved by periods of colder weather and impaired by periods of warmer weather, so any changes in climate couldaffect the market for our products and services. If there is an overall trend of warmer temperatures, it would be expected to have an adverse effect on ourbusiness.Because propane is considered a clean alternative fuel under the federal Clean Air Act Amendments of 1990, new climate change regulations mayprovide us with a competitive advantage over other sources of energy, such as fuel oil and coal.The trend of more expansive and stringent environmental legislation and regulations, including greenhouse gas regulation, could continue,resulting in increased costs of conducting business and consequently affecting our profitability. To the extent laws are enacted or other governmental actionis taken that restricts certain aspects of our business or imposes more stringent and costly operating, waste handling, disposal and cleanup requirements, ourbusiness and prospects could be adversely affected.Safety and TransportationAll states in which we operate have adopted fire safety codes that regulate the storage and distribution of propane and distillates. In some states, stateagencies administer these laws. In others, municipalities administer them. We conduct training programs to help ensure that our operations comply withapplicable governmental regulations. With respect to general operations, each state in which we operate adopts National Fire Protection Association,Pamphlet Nos. 54 and 58, or comparable regulations, which establish rules and procedures governing the safe handling of propane, and Pamphlet Nos. 30,30A, 31, 385, and 395 which establish rules and procedures governing the safe handling of distillates, such as fuel oil. We believe that the policies andprocedures currently in effect at all of our facilities for the handling, storage and distribution of propane and distillates and related service and installationoperations are consistent with industry standards and are in compliance in all material respects with applicable environmental, health and safety laws.With respect to the transportation of propane, distillates, crude oil, and water, we are subject to regulations promulgated under federal legislation,including the Federal Motor Carrier Safety Act and the Homeland Security Act of 2002. Regulations under these statutes cover the security andtransportation of hazardous materials and are administered by the DOT. Specifically, crude oil pipelines are subject to regulation by the DOT, through thePipeline and Hazardous Materials Safety Administration (“PHMSA”), under the Hazardous Liquid Pipeline Safety Act of 1979 (“HLPSA”), which requiresPHMSA to develop, prescribe, and enforce minimum federal safety standards for the storage and transportation of hazardous liquids by and comparable statestatutes with respect to design, installation, testing, construction, operation, replacement and management of pipeline facilities. HLPSA covers petroleum andpetroleum products and requires any entity that owns or operates pipeline facilities to comply with such regulations, to permit access to and copying ofrecords and to file certain reports and provide information as required by the United States Secretary of Transportation. These regulations include potentialfines and penalties for violations.The Pipeline Safety Act of 1992 added the environment to the list of statutory factors that must be considered in establishing safety standards forhazardous liquid pipelines, established safety standards for certain “regulated gathering lines,” and mandated that regulations be issued to establish criteriafor operators to use in identifying and inspecting pipelines located in high consequence areas (“HCAs”), defined as those areas that are unusually sensitive toenvironmental damage, that cross a navigable waterway, or that have a high population density. In the Pipeline Inspection, Protection, Enforcement, andSafety Act of 2006, Congress required mandatory inspections for certain United States crude oil and natural gas transmission pipelines in HCAs andmandated that regulations be issued for low-stress hazardous liquid pipelines and pipeline control room management. In January 2012, the federalgovernment passed the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (the “2011 Pipeline Safety Act”). This act provides for additionalregulatory oversight of the nation’s pipelines,27Table of Contentsincreases the penalties for violations of pipeline safety rules, and complements the DOT’s other initiatives. The 2011 Pipeline Safety Act increases themaximum fine for the most serious pipeline safety violations involving deaths, injuries or major environmental harm from $1 million to $2 million. Inaddition, this law established additional safety requirements for newly constructed pipelines. The law also provides for (i) additional pipeline damageprevention measures; (ii) allowing the Secretary of Transportation to require automatic and remote-controlled shut-off valves on new pipelines; (iii) requiringthe Secretary of Transportation to evaluate the effectiveness of expanding pipeline integrity management and leak detection requirements; (iv) improving theway the DOT and pipeline operators provide information to the public and emergency responders; and (v) reforming the process by which pipeline operatorsnotify federal, state and local officials of pipeline accidents. On June 22, 2016, the Protecting Our Infrastructure of Pipelines and Enhancing Safety Act of2016 was enacted, further strengthening PHMSA’s safety authority.Railcar RegulationWe transport a significant portion of our natural gas liquids, crude oil, ethanol and biodiesel via rail transportation, and we own and lease a fleet ofrailcars for this purpose. Our railcar operations are subject to the regulatory jurisdiction of the Federal Railroad Administration of the DOT, as well as otherfederal and state regulatory agencies.In May 2015, the DOT finalized new regulations applicable to “high hazard flammable trains.” The final rule created a new North American tank carstandard known as the DOT Specification 117, or DOT-117, railcar with thicker steel and redesigned bottom outlet valves, compared to the DOT-111 tankcar. In addition, the adoption of additional federal, state or local laws or regulations, including any voluntary measures by the rail industry regarding railcardesign or crude oil rail transport activities, or efforts by local communities to restrict or limit rail traffic involving crude oil, could similarly affect ourbusiness by increasing compliance costs and decreasing demand for our services, which could adversely affect our financial position and cash flows.Occupational Health RegulationsThe workplaces associated with our manufacturing, processing, terminal, storage facilities and distribution facilities are subject to the requirementsof the federal Occupational Safety and Health Act (“OSHA”) and comparable state statutes. We believe we have conducted our operations in substantialcompliance with OSHA requirements, including general industry standards, record keeping requirements and monitoring of occupational exposure toregulated substances. Our marine vessel operations are also subject to safety and operational standards established and monitored by the United States CoastGuard. In general, we expect to increase our expenditures relating to compliance with likely higher industry and regulatory safety standards such as thosedescribed above. However, these expenditures cannot be accurately estimated at this time, but we do not expect them to have a material adverse effect on ourbusiness.Available Information on our WebsiteOur website address is http://www.nglenergypartners.com.

Risk FactorsRisks Related to Our BusinessWe may not have sufficient cash to enable us to pay the minimum quarterly distribution to our unitholders following the establishment of cash reserves byour general partner and the payment of costs and expenses, including reimbursement of expenses to our general partner.28Table of ContentsWe may not have sufficient cash to enable us to pay the minimum quarterly distribution. These distributions may only be made from cash availablefor distribution after the preferred quarterly distribution to which our preferred units are entitled. The amount of cash we can distribute on our unitsprincipally depends on the amount of cash we generate from our operations, which will fluctuate from quarter to quarter based on, among other things:•weather conditions in our operating areas;•the cost of crude oil, natural gas liquids, gasoline, diesel, ethanol, and biodiesel that we buy for resale and whether we are able to pass along costincreases to our customers;•the volume of wastewater delivered to our processing facilities;•disruptions in the availability of crude oil and/or natural gas liquids supply;•our ability to renew leases for storage and railcars;•the effectiveness of our commodity price hedging strategy;•the level of competition from other energy providers; and•prevailing economic conditions.In addition, the actual amount of cash we will have available for distribution also depends on other factors, some of which are beyond our control,including:•the level of capital expenditures we make;•the cost of acquisitions, if any;•restrictions contained in our credit agreement (the “Credit Agreement”), the indentures governing our outstanding 5.125% senior notes due2019, 6.875% senior notes due 2021, 7.50% senior notes due 2023, and 6.125% senior notes due 2025 (collectively, the “Indentures”) andother debt service requirements;•restrictions contained in our 10.75% Class A Convertible Preferred Units and 9.00% Class B Fixed-to-Floating Cumulative RedeemablePerpetual Preferred Unit agreements;•fluctuations in working capital needs;•our ability to borrow funds and access capital markets;•the amount, if any, of cash reserves established by our general partner; and•other business risks discussed in this Annual Report that may affect our cash levels.The amount of cash we have available for distribution to our unitholders depends primarily on our cash flow rather than on our profitability, which mayprevent us from making distributions, even during periods in which we realize net income.The amount of cash we have available for distribution depends primarily on our cash flow and not solely on profitability, which will be affected bynon-cash items. As a result, we might make cash distributions during periods when we record net losses for financial accounting purposes and we might notmake cash distributions during periods when we record net income for financial accounting purposes.Our future financial performance and growth may be limited by our ability to successfully grow organically and complete accretive acquisitions oneconomically acceptable terms.Our ability to complete accretive acquisitions on economically acceptable terms may be limited by various factors, including, but not limited to:•increased competition for attractive acquisitions;•covenants in our Credit Agreement and Indentures that limit the amount and types of indebtedness that we may incur to finance acquisitionsand which may adversely affect our ability to make distributions to our unitholders;•lack of available cash or external capital or limitations on our ability to issue equity to pay for acquisitions; and•possible unwillingness of prospective sellers to accept our common units as consideration and the potential dilutive effect to our existingunitholders caused by an issuance of common units in an acquisition.29Table of ContentsThere can be no assurance that we will identify attractive acquisition candidates in the future, that we will be able to acquire such businesses oneconomically acceptable terms, that any acquisitions will not be dilutive to earnings and distributions or that any additional debt that we incur to finance anacquisition will not adversely affect our ability to make distributions to unitholders. Furthermore, if we consummate any future acquisitions, ourcapitalization and results of operations may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial and otherrelevant information that we will consider in determining the application of these funds and other resources.We may be subject to substantial risks in connection with the integration and operation of acquired businesses, in particular those businesses withoperations that are distinct and separate from our existing operations.Any acquisitions we make in pursuit of our growth strategy are subject to potential risks, including, but not limited to:•the inability to successfully integrate the operations of recently acquired businesses;•the assumption of known or unknown liabilities, including environmental liabilities;•limitations on rights to indemnity from the seller;•mistaken assumptions about the overall costs of equity, debt or synergies;•mistaken assumptions about sales volume, margin or operational expenses;•unforeseen difficulties operating in new geographic areas or in new business segments;•the diversion of management’s and employees’ attention from other business concerns;•customer or key employee loss from the acquired businesses; and•a potential significant increase in our indebtedness and related interest expense.We undertake due diligence efforts in our assessment of acquisitions, but may be unable to identify or fully plan for all issues and risks associatedwith a particular acquisition. Even when an issue or risk is identified, we may be unable to obtain adequate contractual protection from the seller. Therealization of any of these risks could have a material adverse effect on the success of a particular acquisition or our consolidated financial position, results ofoperations or future growth.As part of our growth strategy, we may expand our operations into businesses that differ from our existing operations. Integration of new businessesis a complex, costly and time-consuming process and may involve assets with which we have limited operating experience. Failure to timely and successfullyintegrate acquired businesses into our existing operations may have a material adverse effect on our business, consolidated financial position or results ofoperations. In addition to the risks set forth above, new businesses will subject us to additional business and operating risks, such as the acquisitions notbeing accretive to our unitholders as a result of decreased profitability, increased interest expense related to debt we incur to make such acquisitions or aninability to successfully integrate those operations into our overall business operations. The realization of any of these risks could have a material adverseeffect on our consolidated financial position or results of operations.Our substantial indebtedness may limit our flexibility to obtain financing and to pursue other business opportunities.At March 31, 2018, the face amount of our long-term debt was $2.7 billion. Our level of debt could have important consequences to us, includingthe following:•our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impairedor such financing may not be available on favorable terms;•our funds available for operations, future business opportunities and distributions to unitholders will be reduced by that portion of our cash flowrequired to make principal and interest payments on our debt;•we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and•our flexibility in responding to changing business and economic conditions may be limited.Our ability to service our debt will depend on, among other things, our future financial and operating performance, which will be affected byprevailing economic and weather conditions, and financial, business, regulatory and other factors, some of which are beyond our control. If our operatingresults are not sufficient to service our future indebtedness, we would be forced to take actions such as reducing distributions, reducing or delaying ourbusiness activities, acquisitions, investments30Table of Contentsor capital expenditures, selling assets or seeking additional equity capital. We may be unable to effect any of these actions on satisfactory terms or at all. Theagreements governing our indebtedness permit us to incur additional debt under certain circumstances, and we will likely need to incur additional debt inorder to implement our growth strategy. We may experience adverse consequences from increased levels of debt.Restrictions in our Credit Agreement and Indentures could adversely affect our business, financial position, results of operations, ability to makedistributions to unitholders and the value of our common units.Our Credit Agreement and Indentures limit our ability to, among other things:•incur additional debt or issue letters of credit;•redeem or repurchase units;•make certain loans, investments and acquisitions;•incur certain liens or permit them to exist;•engage in sale and leaseback transactions;•enter into certain types of transactions with affiliates;•enter into agreements limiting subsidiary distributions;•change the nature of our business or enter into a substantially different business;•merge or consolidate with another company; and•transfer or otherwise dispose of assets.We are permitted to make distributions to our unitholders under our Credit Agreement and Indentures as long as no default or event of default existsboth immediately before and after giving effect to the declaration and payment of the distribution and the distribution does not exceed available cash for theapplicable quarterly period. Our Credit Agreement and Indentures also contain covenants requiring us to maintain certain financial ratios. See Note 8 to ourconsolidated financial statements included in this Annual Report for a further discussion.The provisions of our Credit Agreement and Indentures may affect our ability to obtain future financing and pursue attractive business opportunitiesand our flexibility in planning for, and reacting to, changes in business conditions. In addition, a failure to comply with the provisions of our CreditAgreement could result in a covenant violation, default or an event of default that could enable our lenders, subject to the terms and conditions of our CreditAgreement, to declare the outstanding principal of that debt, together with accrued and unpaid interest, to be immediately due and payable. If we were unableto repay the accelerated amounts, our lenders could proceed against the collateral we granted them to secure our debts. If the payment of our debt isaccelerated, defaults under our other debt instruments, if any then exist, may be triggered, and our assets may be insufficient to repay such debt in full, andour unitholders could experience a partial or total loss of their investment.Increases in interest rates could adversely impact our common unit price, our ability to issue equity or incur debt for acquisitions or other purposes, andour ability to make cash distributions at our intended levels.Interest rates may increase in the future. As a result, interest rates on our existing and future credit facilities and debt offerings could be higher thancurrent levels, causing our financing costs to increase accordingly. As with other yield-oriented securities, our common unit price will be impacted by ourlevel of cash distributions and implied distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities forinvestment decision-making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors whoinvest in our common units, and a rising interest rate environment could have an adverse impact on our common unit price and our ability to issue equity orincur debt for acquisitions or other purposes and to make payments on our debt obligations and cash distributions at our intended levels.31Table of ContentsOur business depends on the availability of crude oil, natural gas liquids, and refined products in the United States and Canada, which is dependent on theability and willingness of other parties to explore for and produce crude oil and natural gas. Spending on crude oil and natural gas exploration andproduction may be adversely affected by industry and financial market conditions that are beyond our control.Our business depends on domestic spending by the oil and natural gas industry, and this spending and our business have been, and may continue tobe, adversely affected by industry and financial market conditions and existing or new regulations, such as those related to environmental matters, that arebeyond our control.We depend on the ability and willingness of other entities to make operating and capital expenditures to explore for, develop, and produce crude oiland natural gas in the United States and Canada, and to extract natural gas liquids from natural gas as well as the availability of necessary pipelinetransportation and storage capacity. Customers’ expectations of lower market prices for crude oil and natural gas, as well as the availability of capital foroperating and capital expenditures, may cause them to curtail spending, thereby reducing business opportunities and demand for our services and equipment.Actual market conditions and producers’ expectations of market conditions for crude oil and natural gas liquids may also cause producers to curtail spending,thereby reducing business opportunities and demand for our services.Industry conditions are influenced by numerous factors over which we have no control, such as the availability of commercially viable geographicareas in which to explore and produce crude oil and natural gas, the availability of liquids-rich natural gas needed to produce natural gas liquids, the supplyof and demand for crude oil and natural gas, environmental restrictions on the exploration and production of crude oil and natural gas, such as existing andproposed regulation of hydraulic fracturing, domestic and worldwide economic conditions, political instability in crude oil and natural gas producingcountries and merger and divestiture activity among our current or potential customers. The volatility of the oil and natural gas industry and the resultingimpact on exploration and production activity could adversely impact the level of drilling activity. This reduction may cause a decline in businessopportunities or the demand for our services, or adversely affect the price of our services. Reduced discovery rates of new crude oil and natural gas reserves inour market areas also may have a negative long-term impact on our business, even in an environment of stronger crude oil and natural gas prices, to the extentexisting production is not replaced.The crude oil and natural gas production industry tends to run in cycles and may, at any time, cycle into a downturn; if that occurs, the rate at whichit returns to former levels, if ever, will be uncertain. Prior adverse changes in the global economic environment and capital markets and declines in prices forcrude oil and natural gas have caused many customers to reduce capital budgets for future periods and have caused decreased demand for crude oil andnatural gas. Limitations on the availability of capital, or higher costs of capital, for financing expenditures have caused and may continue to cause customersto make additional reductions to capital budgets in the future even if commodity prices increase from current levels. These cuts in spending may curtaildrilling programs and other discretionary spending, which could result in a reduction in business opportunities and demand for our services, the rates we cancharge and our utilization. In addition, certain of our customers could become unable to pay their suppliers, including us. Any of these conditions or eventscould materially and adversely affect our consolidated results of operations.Declining crude oil prices could adversely impact our Water Solutions and Crude Oil Logistics businesses.Crude oil spot and forward prices experienced a sharp decline during the second half of calendar year 2014. While crude oil prices have reboundedfrom the lows experienced during the first three months of calendar year 2016, they are still well below the prices from the first half of calendar year 2014.This has had an unfavorable impact on the revenues of our Water Solutions business. The volume of water we process is driven in part by the level of crudeoil production, and the lower crude oil prices have given producers less incentive to expand production. In addition, a portion of the revenues in our WaterSolutions business is generated from the sale of hydrocarbons that we recover when processing wastewater, and lower crude oil prices have an adverse impacton these revenues. A further decline in crude oil prices or a prolonged period of low crude oil prices could have an adverse effect on our Water Solutionsbusiness.In addition, the sharp decline in crude oil prices has reduced the incentive for producers to expand production. If crude oil prices remain low,resultant declines in crude oil production could adversely impact volumes in our Crude Oil Logistics business.Our profitability could be negatively impacted by price and inventory risk related to our business.The Crude Oil Logistics, Liquids, Retail Propane, and Refined Products and Renewables businesses are “margin-based” businesses in which ourrealized margins depend on the differential of sales prices over our total supply costs. Our32Table of Contentsprofitability is therefore sensitive to changes in product prices caused by changes in supply, pipeline transportation and storage capacity or other marketconditions.Generally, we attempt to maintain an inventory position that is substantially balanced between our purchases and sales, including our futuredelivery obligations. We attempt to obtain a certain margin for our purchases by selling our product to our customers, which include third-party consumers,other wholesalers and retailers, and others. However, market, weather or other conditions beyond our control may disrupt our expected supply of product, andwe may be required to obtain supply at increased prices that cannot be passed through to our customers. In general, product supply contracts permit suppliersto charge posted prices at the time of delivery or the current prices established at major storage points, creating the potential for sudden and drastic pricefluctuations. Sudden and extended wholesale price increases could reduce our margins and could, if continued over an extended period of time, reducedemand by encouraging retail customers to conserve or convert to alternative energy sources. Conversely, a prolonged decline in product prices couldpotentially result in a reduction of the borrowing base under our working capital facility, and we could be required to liquidate inventory that we havealready presold.One of the strategies of our Refined Products and Renewables segment is to purchase refined products in the Gulf Coast region and to transport theproduct on the Colonial pipeline for sale in the Southeast and East Coast. Spreads between product prices in the Gulf Coast compared to locations along theColonial pipeline can vary significantly, which can create volatility in our product margins. In addition, we are subject to the risk of a price decline betweenthe time we purchase refined products and the time we sell the products. We seek to mitigate this risk by entering into NYMEX futures contracts. However,price changes in locations where we operate do not correspond directly with changes in prices in the NYMEX futures market, and as a result these futurescontracts cannot be perfect hedges of our commodity price risk.We are affected by competition from other midstream, transportation, terminaling and storage, and retail-marketing companies, some of which are largerand more firmly established and may have greater resources than we do.We experience competition in all of our segments. In our Liquids segment, we compete for natural gas liquids supplies and also for customers for ourservices. 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 liquids terminals compete with other terminaling and storage providers in the transportation andstorage of natural gas liquids. Natural gas and natural gas liquids also compete with other forms of energy, including electricity, coal, fuel oil and renewableor alternative energy.Our Crude Oil Logistics segment faces significant competition for crude oil supplies and also for customers for our services. These operations alsoface competition from trucking companies for incremental and marginal volumes in the areas we serve. Further, our crude oil terminals compete withterminals owned by integrated petroleum companies, refining and marketing companies, independent terminal companies and distribution companies withmarketing and trading operations.Our Water Solutions segment is in direct and indirect competition with other businesses, including disposal and other wastewater treatmentbusinesses.We face strong competition in the market for the sale of retail propane and distillates. Our competitors vary from retail propane companies who arelarger and have greater financial resources than we do to small independent retail propane distributors, agricultural cooperatives and fuel oil distributors whohave entered the market due to a low barrier to entry. The actions of our retail propane and distillate competitors and the impact of imports/exports could leadto lower prices or reduced margins for the products we sell, which could have an adverse effect on our business or consolidated results of operations.Our Refined Products and Renewables segment also faces significant competition for refined products and renewables supplies and also forcustomers for our services.We can make no assurance that we will compete successfully in each of our lines of business. If a competitor attempts to increase market share byreducing prices, we may lose customers, which would reduce our revenues.Our business would be adversely affected if service at our principal storage facilities or on the common carrier pipelines or railroads we use is interrupted.We use third-party common carrier pipelines to transport our products and we use third-party facilities to store our products. Any significantinterruption in the service at these storage facilities or on the common carrier pipelines we use would adversely affect our ability to obtain products. Wetransport crude oil, natural gas liquids, ethanol, and biodiesel by railcar. We33Table of Contentsdo not own or operate the railroads on which these railcars are transported. Any disruptions in the operations of these railroads could adversely impact ourability to deliver product to our customers.The fees charged to customers under our agreements with them for the transportation and marketing of crude oil, condensate, natural gas liquids,gasoline, diesel, ethanol, and biodiesel may not escalate sufficiently to cover increases in costs and the agreements may be suspended in somecircumstances, which would affect our profitability.Our costs may increase more rapidly than the fees that we charge to customers pursuant to our contracts with them. Additionally, some customers’obligations under their agreements with us may be permanently or temporarily reduced upon the occurrence of certain events, some of which are beyond ourcontrol, including force majeure events wherein the supply of crude oil, condensate, and/or natural gas liquids are curtailed or cut off. Force majeure eventsinclude (but are not limited to) revolutions, wars, acts of enemies, embargoes, import or export restrictions, strikes, lockouts, fires, storms, floods, acts of God,explosions, mechanical or physical failures of our equipment or facilities of our customers. If the escalation of fees is insufficient to cover increased costs, orif any customer suspends or terminates its contracts with us, our profitability could be materially and adversely affected.Our sales of crude oil, condensate, natural gas liquids, gasoline, diesel, ethanol, and biodiesel and related transportation and hedging activities, and ourprocessing of wastewater, expose us to potential regulatory risks.The FTC, the FERC, and the CFTC hold statutory authority to monitor certain segments of the physical and financial energy commodity markets.With regard to our physical sales of energy commodities, and any related transportation and/or hedging activities that we undertake, we are required toobserve the market-related regulations enforced by these agencies, which hold substantial enforcement authority. Our sales may also be subject to certainreporting and other requirements. Additionally, some of our operations are currently subject to the FERC regulations obligating us to comply with theFERC’s regulations and policies applicable to those assets and operations. Other of our operations may become subject to the FERC’s jurisdiction in thefuture (see “–Some of our operations are subject to the jurisdiction of the FERC and other operations may become subject in the future,” below). Any failureon our part to comply with the FERC’s regulations and policies at that time could result in the imposition of civil and criminal penalties. Failure to complywith such regulations, as interpreted and enforced, could have a material and adverse effect on our business, consolidated results of operations and financialposition.The intrastate transportation or storage of crude oil and refined products is subject to regulation by the state in which the facilities are located andtransactions occur. Compliance with these state regulations could have a material and adverse effect on that portion of our business, consolidated results ofoperations and financial position.The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) provides for statutory and regulatory requirements forderivative transactions, including crude oil, refined and renewable products, and natural gas hedging transactions. Certain transactions will be required to becleared on exchanges and cash collateral will have to be posted. The Dodd-Frank Act provides for a potential exemption from these clearing and cashcollateral requirements for commercial end users and it includes a number of defined terms that will be used in determining how this exemption applies toparticular derivative transactions and the parties to those transactions. Since the Dodd-Frank Act mandates the CFTC to promulgate rules to define theseterms, the full impact of the Dodd-Frank Act on our hedging activities is uncertain at this time. However, new legislation and any new regulations couldsignificantly increase the cost of derivative contracts (including through requirements to post collateral which could adversely affect our available liquidity),materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks that we encounter, reduce our ability tomonetize or restructure our existing derivative contracts, and increase our exposure to less creditworthy counterparties. The Dodd-Frank Act may alsomaterially affect our customers and materially and adversely affect the demand for our services.We are subject to trucking safety regulations, which are enacted, reviewed and amended by the Federal Motor Carrier Safety Administration (“FMCSA”).If our current DOT safety ratings are downgraded to “Unsatisfactory”, our business and results of our operations may be adversely affected.All federally regulated carriers’ safety ratings are measured through a program implemented by the FMCSA known as the Compliance SafetyAccountability (“CSA”) program. The CSA program measures a carrier’s safety performance based on violations observed during roadside inspections asopposed to compliance audits performed by the FMCSA. The quantity and severity of any violations are compared to a peer group of companies ofcomparable size and annual mileage. If a company rises above a threshold established by the FMCSA, it is subject to action from the FMCSA. There is aprogressive intervention strategy that begins with a company providing the FMCSA with an acceptable plan of corrective action that the company willimplement. If the issues are not corrected, the intervention escalates to on-site compliance audits and ultimately an “unsatisfactory” rating and the revocationof the company’s operating authority by the FMCSA, which could result in a34Table of Contentsmaterial adverse effect on our business, consolidated results of operations and financial position and ability to make cash distributions to our unitholders. Our business is subject to federal, state, provincial and local laws and regulations with respect to environmental, safety and other regulatory matters andthe cost of compliance with, violation of or liabilities under, such laws and regulations could adversely affect our profitability.Our operations, including those involving crude oil, condensate, natural gas liquids, refined products, renewables, and crude oil and natural gasproduced wastewater, are subject to stringent federal, state, provincial and local laws and regulations relating to the protection of natural resources and theenvironment, health and safety, waste management, and transportation and disposal of such products and materials. We face inherent risks of incurringsignificant environmental costs and liabilities due to handling of wastewater and hydrocarbons, such as crude oil, condensate, natural gas liquids, gasoline,diesel, ethanol, and biodiesel. For instance, our Water Solutions business carries with it environmental risks, including leakage from the treatment plants tosurface or subsurface soils, surface water or groundwater, or accidental spills. Our Crude Oil Logistics, Liquids, and Refined Products and Renewablesbusinesses carry similar risks of leakage and sudden or accidental spills of crude oil, natural gas liquids, and hydrocarbons. Liability under, or violation of,environmental laws and regulations could result in, among other things, the impairment or cancellation of operations, injunctions, fines and penalties,reputational damage, expenditures for remediation and liability for natural resource damages, property damage and personal injuries.We use various modes of transportation to carry propane, distillates, crude oil, refined and renewable products and water, including trucks, railcars,barges, and pipelines, each of which is subject to regulation. With respect to transportation by truck, we are subject to regulations promulgated under federallegislation, including the Federal Motor Carrier Safety Act and the Homeland Security Act of 2002, which cover the security and transportation of hazardousmaterials and are administered by the DOT. We also own and lease a fleet of railcars, the operation of which is subject to the regulatory jurisdiction of theFederal Railroad Administration of the DOT, as well as other federal and state regulatory agencies. Railcar accidents within the industry involving trainscarrying crude oil from the Bakken region (none of which directly involved any of our business operations), have led to increased legislative and regulatoryscrutiny over the safety of transporting crude oil by railcar. The introduction of regulations that result in new requirements addressing the type, design,specifications or construction of railcars used to transport crude oil could result in severe transportation capacity constraints during the periods in whichnew railcars are constructed to meet new specifications or in which the railcars already placed in service are being retrofitted. Our barge transportationoperations are subject to the Jones Act, a federal law generally restricting marine transportation in the United States to vessels built and registered in theUnited States, and manned/owned by United States citizens, as well as setting forth the rules and regulations of the United States Coast Guard. Non-compliance with any of these regulations could result in increased costs related to the transportation of our products and could have an adverse effect on ourbusiness.In addition, under certain environmental laws, we could be subject to strict and/or joint and several liability for the investigation, removal orremediation of previously released materials. As a result, these laws could cause us to become liable for the conduct of others, such as prior owners oroperators of our facilities, or for consequences of our or our predecessor’s actions, regardless of whether we were responsible for the release or if such actionswere in compliance with all applicable laws at the time of those actions. Also, upon closure of certain facilities, such as at the end of their useful life, we havebeen and may be required to undertake environmental evaluations or cleanups.Additionally, in order to conduct our operations, we must obtain and maintain numerous permits, approvals and other authorizations from variousfederal, state, provincial and local governmental authorities relating to wastewater handling, discharge and disposal, air emissions, transportation and otherenvironmental matters. These authorizations subject us to terms and conditions which may be onerous or costly to comply with, and that may require costlyoperational modifications to attain and maintain compliance. The renewal, amendment or modification of these permits, approvals and other authorizationsmay involve the imposition of even more stringent and burdensome terms and conditions with attendant higher costs and more significant effects upon ouroperations.Changes in environmental laws and regulations occur frequently. New laws or regulations, changes to existing laws or regulations, such as morestringent pollution control requirements or additional safety requirements, or more stringent interpretation or enforcement of existing laws and regulations,may adversely impact us, and could result in increased operating costs and have a material and adverse effect on our activities and profitability. For example,new or proposed laws or regulations governing the withdrawal, storage and use of surface water or groundwater necessary for hydraulic fracturing of wellsmay increase our costs for treatment of hydraulic fracturing flowback water (or affect our hydraulic fracturing customers’ ability to operate) and cause delays,interruption or termination of our water treatment operations, all of which could have a material and adverse effect on our consolidated results of operationsand financial position.35Table of ContentsFurthermore, our customers in the oil and gas production industry are subject to certain environmental laws and regulations that may imposesignificant costs and liabilities on them. Any significant increased costs or restrictions placed on our customers to comply with environmental laws andregulations could affect their production output significantly. Such an effect on our customers could materially and adversely affect our utilization andprofitability by reducing demand for our services. The adoption or implementation of any new regulations imposing additional reporting obligations ongreenhouse gas emissions, or limiting greenhouse gas emissions from our equipment and operations, could require us to incur significant costs.State legislation and regulatory initiatives relating to our hydraulic fracturing customers could harm our business.Hydraulic fracturing is a frequent practice in the crude oil and natural gas fields in which our Water Solutions segment operates. Hydraulic fracturingis an important and common process used to facilitate production of natural gas and other hydrocarbon condensates in shale formations, as well as tightconventional formations. The hydraulic fracturing process is primarily regulated by state oil and gas authorities. This process has come under considerablescrutiny from sections of the public as well as environmental and other groups asserting that chemicals used in the hydraulic fracturing process couldadversely affect drinking water supplies. New laws or regulations, or changes to existing laws or regulations in response to this perceived threat mayadversely impact the oil and gas drilling industry. Any current or proposed restrictions on hydraulic fracturing could lead to operational delays or increasedoperating costs and regulatory burdens that could make it more difficult or costly to perform hydraulic fracturing which would negatively impact ourcustomer base resulting in an adverse effect on our profitability.Federal and state legislation and regulatory initiatives relating to saltwater disposal wells could result in increased costs and additional operatingrestrictions or delays and could harm our business.The water disposal process is primarily regulated by state oil and gas authorities. This water disposal process has come under scrutiny from sectionsof the public as well as environmental and other groups asserting that the operation of certain water disposal wells has caused increased seismic activity. Newlaws or regulations, or changes to existing laws or regulations, in response to this perceived threat may adversely impact the water disposal industry.On certain occasions, a state regulatory agency has requested that we suspend operations at a specified disposal facility, pending further study of itspotential impact on seismic activity. In one instance we have modified a disposal well to redirect the flow of water to a different area of the geologicformation in order to address such concerns.We cannot predict whether any federal, state or local laws or regulations will be enacted and, if so, what actions any such laws or regulations wouldrequire or prohibit. However, any restrictions on water disposal could lead to operational delays or increased operating costs and regulatory burdens thatcould make it more difficult or costly to perform water disposal operations, which would negatively impact our profitability.Seasonal weather conditions and natural or man-made disasters could severely disrupt normal operations and have an adverse effect on our business,financial position and results of operations.We operate in various locations across the United States and Canada which may be adversely affected by seasonal weather conditions and natural orman-made disasters. During periods of heavy snow, ice, rain or extreme weather conditions such as high winds, tornados and hurricanes or after other naturaldisasters such as earthquakes or wildfires, we may be unable to move our trucks or railcars between locations and our facilities may be damaged, therebyreducing our ability to provide services and generate revenues. In addition, hurricanes or other severe weather in the Gulf Coast region could seriouslydisrupt the supply of products and cause serious shortages in various areas, including the areas in which we operate. These same conditions may cause seriousdamage or destruction to homes, business structures and the operations of customers. Such disruptions could potentially have a material adverse impact onour business, consolidated financial position, results of operations and cash flows.Risk management procedures cannot eliminate all commodity risk, basis risk, or risk of adverse market conditions which can adversely affect our financialposition and results of operations. In addition, any non-compliance with our risk policy could result in significant financial losses.Pursuant to the requirements of our market risk policy, we attempt to lock in a margin for a portion of the commodities we purchase by selling suchcommodities for physical delivery to our customers, such as independent refiners or major oil companies, or by entering into future delivery obligationsunder contracts for forward sale. We also enter into financial derivative contracts, such as futures, to manage commodity price risk. Through thesetransactions, we seek to maintain a position that is substantially balanced between purchases on the one hand, and sales or future delivery obligations on theother36Table of Contentshand. These policies and practices cannot, however, eliminate all risks. For example, any event that disrupts our anticipated physical supply of commoditiescould expose us to risk of loss resulting from the need to cover obligations required under contracts for forward sale. Additionally, we can provide noassurance that our processes and procedures will detect and/or prevent all violations of our risk management policies and procedures, particularly ifdeception or other intentional misconduct is involved.Basis risk describes the inherent market price risk created when a commodity of certain grade or location is purchased, sold or exchanged ascompared to a purchase, sale or exchange of a like commodity at a different time or place. Transportation costs and timing differentials are components ofbasis risk. In a backwardated market (when prices for future deliveries are lower than current prices), basis risk is created with respect to timing. In theseinstances, physical inventory generally loses value as the price of such physical inventory declines over time. Basis risk cannot be entirely eliminated, andbasis exposure, particularly in backwardated or other adverse market conditions, can adversely affect our consolidated financial position and results ofoperations.The counterparties to our commodity derivative and physical purchase and sale contracts may not be able to perform their obligations to us, which couldmaterially affect our cash flows and results of operations.We encounter risk of counterparty nonperformance in our businesses. Disruptions in the supply of product and in the crude oil and natural gascommodities sector overall for an extended or near term period of time could result in counterparty defaults on our derivative and physical purchase and salecontracts. This could impair our ability to obtain supply to fulfill our sales delivery commitments or obtain supply at reasonable prices, which could result indecreased gross margins and profitability, thereby impairing our ability to make payments on our debt obligations or distributions to our unitholders.Our use of derivative financial instruments could have an adverse effect on our results of operations.We have used derivative financial instruments as a means to protect against commodity price risk or interest rate risk and expect to continue to doso. We may, as a component of our overall business strategy, increase or decrease from time to time our use of such derivative financial instruments in thefuture. Our use of such derivative financial instruments could cause us to forego the economic benefits we would otherwise realize if commodity prices orinterest rates were to change in our favor. In addition, although we monitor such activities in our risk management processes and procedures, such activitiescould result in losses, which could adversely affect our consolidated results of operations and impair our ability to make payments on our debt obligations ordistributions to our unitholders.Some of our operations are subject to the jurisdiction of the FERC and other operations may become subject in the future.The FERC regulates the transportation of crude oil and refined products on interstate pipelines, among other things. Intrastate transportation andgathering pipelines that do not provide interstate services are not subject to regulation by the FERC. The distinction between the FERC-regulated interstatepipeline transportation on the one hand and intrastate pipeline transportation on the other hand, is a fact-based determination. The Grand Mesa Pipelinebecame operational on November 1, 2016 and has several points of origin in Colorado, runs from those origin points through Kansas and terminates inCushing, Oklahoma. The transportation services on the Grand Mesa Pipeline are subject to FERC regulation. Other of our transportation services could in thefuture become subject to the jurisdiction of the FERC, which could adversely affect the terms of service, rates and revenues of such services.The classification and regulation of our crude oil pipelines are subject to change based on future determinations by the FERC, federal courts,Congress or regulatory commissions, courts or legislatures in the states in which we operate. If the FERC’s regulatory reach was expanded to our otherfacilities, or if we expand our operations into areas that are subject to the FERC’s regulation, we may have to commit substantial capital to comply with suchregulations and such expenditures could have a material and adverse effect on our consolidated results of operations and cash flows.Volumes of hydrocarbons recovered during the wastewater treatment process can vary. Any significant reduction in residual crude oil content inwastewater we treat will affect our recovery of hydrocarbons and, therefore, our profitability.A portion of the revenues in our Water Solutions business is generated from the sale of hydrocarbons that we recover when processing wastewater.Our ability to recover sufficient volumes of hydrocarbons is dependent upon the residual crude oil content in the wastewater we treat, which is, among otherthings, a function of water temperature. Generally, where water temperature is higher, residual crude oil content is lower. Thus, our crude oil recovery duringthe winter season is substantially higher than our recovery during the summer season. Additionally, residual crude oil content will decrease if, among otherthings, producers begin recovering higher levels of crude oil in produced wastewater prior to delivering such water to us for37Table of Contentstreatment. Any reduction in residual crude oil content in the wastewater we treat could materially and adversely affect our profitability.Competition from alternative energy sources may cause us to lose customers, thereby negatively impacting our financial position and results of operations.Propane competes with other sources of energy, some of which are less costly for equivalent energy value. We compete for customers againstsuppliers of electricity, natural gas and fuel oil. Competition from alternative energy sources, including electricity, natural gas and renewables, has increasedas a result of reduced regulation of many utilities. Electricity is a major competitor of propane, but propane in some regions has historically had a competitiveprice advantage over electricity. Except for some industrial and commercial applications, propane is generally not competitive with natural gas in areaswhere natural gas pipelines already exist because such pipelines generally make it possible for the delivered cost of natural gas to be less expensive than thebulk delivery of propane. The expansion of natural gas into traditional propane markets has historically been inhibited by the capital cost required to expanddistribution and pipeline systems; however, the gradual expansion of the nation’s natural gas distribution systems has resulted in natural gas being availablein areas that previously depended on propane, which could cause us to lose customers, thereby reducing our revenues. Although propane is similar to fuel oilin some applications and market demand, propane and fuel oil compete to a lesser extent primarily because of the cost of converting from one to the other.We cannot predict the effect that development of alternative energy sources may have on our operations, including whether subsidies of alternativeenergy sources by local, state, and federal governments might be expanded, or what impact this might have on the supply of or the demand for crude oil,natural gas, and natural gas liquids.Energy efficiency and new technology may reduce the demand for propane and adversely affect our operating results.The national trend toward increased conservation and technological advances, such as installation of improved insulation and the development ofmore efficient furnaces and other appliances, has adversely affected the demand for propane and distillates by retail customers. Future conservation measuresor technological advances in appliance efficiency, power generation or other devices may reduce demand for propane. In addition, if the price of propaneincreases, some of our customers may increase their conservation efforts and thereby decrease their consumption of propane.The majority of our retail propane operations are geographically concentrated and localized warmer weather and/or economic downturns may adverselyaffect demand for propane, thereby affecting our financial position and results of operations.A substantial portion of our retail propane sales are to residential customers located in the northeastern, southeastern, and mid-Atlantic sections ofthe United States who rely heavily on propane for heating purposes. A significant percentage of our retail propane volume is attributable to sales during thepeak heating season of October through March. Warmer weather may result in reduced sales volumes that could adversely impact our consolidated results ofoperations and financial position. In addition, adverse economic conditions in areas where our retail propane operations are concentrated may cause ourresidential customers to reduce their use of propane regardless of weather conditions. Localized warmer weather and/or economic downturns may have asignificantly greater impact on our consolidated results of operations and financial position than if our Retail Propane business were less concentrated.Reduced demand for refined products could have an adverse effect our results of operations.Any sustained decrease in demand for refined products in the markets we serve could reduce our cash flow. Factors that could lead to a decrease inmarket demand include:•a recession or other adverse economic condition that results in lower spending by consumers on gasoline, diesel, and travel;•higher fuel taxes or other governmental or regulatory actions that increase, directly or indirectly, the cost of gasoline;•an increase in automotive engine fuel economy, whether as a result of a shift by consumers to more fuel-efficient vehicles or technologicaladvances by manufacturers;•an increase in the market price of crude oil that leads to higher refined product prices, which may reduce demand for refined products and drivedemand for alternative products; and38Table of Contents•the increased use of alternative fuel sources, such as battery-powered engines.Recent attempts to reduce or eliminate the federal Renewable Fuels Standard (“RFS”), if successful, could adversely impact our results of operations.The United States renewables industry is highly dependent on several federal and state incentives which promote the use of renewable fuels.Without these incentives, demand for and the price of renewable fuels could be negatively impacted which could have an adverse effect on our consolidatedresults of operations. The most significant of the federal and state incentives which benefit renewable products we market, such as ethanol and biodiesel, isthe RFS. The RFS requires that an increasing amount of renewable fuels must be blended with petroleum-based fuels each year in the United States. However,the EPA has authority to waive the requirements of the RFS, in whole or in part, if certain conditions are met. Opponents of the RFS have sought, and maycontinue to seek, to force the EPA to reduce or eliminate the RFS. Further, legislation has been introduced with the goal of significantly reducing oreliminating the RFS. While the outcome of these legislative efforts is uncertain, it is possible that the EPA could adjust the RFS requirements in the future. Ifthe EPA were to adjust the RFS requirements in any material way, it could negatively impact demand for the renewable fuel products we market, which couldadversely impact our consolidated results of operations.The expiration of tax credits could adversely impact the demand for biodiesel, which could adversely impact our results of operationsThe demand for biodiesel is supported by certain federal tax credits. These tax credits have typically been granted for short durations, and on severaloccasions these tax credits have expired. In December 2014, the federal government passed a law reinstating the tax credit retroactively to January 1, 2014 tobe effective through December 31, 2014. In December 2015, the federal government re-signed the law reinstating the tax credit retroactively to January 1,2015 to be effective through December 31, 2016. In February 2018, the federal government passed a law to reinstate the tax credit retroactively to January 1,2017, with the credit expiring on December 31, 2017. There can be no assurance that the federal government will grant such tax credits in the future. If thefederal government were to discontinue the practice of granting such tax credits, this would likely have an adverse effect on demand for biodiesel and on ourbiodiesel marketing operations.A loss of one or more significant customers could materially or adversely affect our results of operations.We expect to continue to depend on key customers to support our revenues for the foreseeable future. The loss of key customers, failure to renewcontracts upon expiration, or a sustained decrease in demand by key customers could result in a substantial loss of revenues and could have a material andadverse effect on our consolidated results of operations. During the year ended March 31, 2018, a significant portion of our revenues was dependent on keycustomers as summarized below:•66% of the revenues of our Crude Oil Logistics segment were generated from our ten largest customers of the segment;•16% of the water treatment and disposal revenues of our Water Solutions segment were generated from our two largest customers of the segment;•27% of the revenues of our Liquids segment were generated from our ten largest customers of the segment (exclusive of sales to our RetailPropane segment); and•35% of the revenues of our Refined Products and Renewables segment were generated from our ten largest customers of the segment.Certain of our operations are conducted through joint ventures which have unique risks.Certain of our operations are conducted through joint ventures. With respect to our joint ventures, we share ownership and managementresponsibilities with partners that may not share our goals and objectives. Differences in views among the partners may result in delayed decisions or failuresto agree on major matters, such as large expenditures or contractual commitments, the construction or acquisition of assets or borrowing money, amongothers. Delay or failure to agree may prevent action with respect to such matters, even though such action may serve our best interest or that of the jointventure. Accordingly, delayed decisions and disagreements could adversely affect the business and operations of the joint ventures and, in turn, our businessand operations. From time to time, our joint ventures may be involved in disputes or legal proceedings which may negatively affect our investments.Accordingly, any such occurrences could adversely affect our consolidated results of operations, financial position and cash flows.39Table of ContentsGrowing our business by constructing new transportation systems and facilities subjects us to construction risks and risks that supplies for such systemsand facilities will not be available upon completion thereof.One of the ways we intend to grow our business is through the construction of additions to our systems and/or the construction of new terminaling,transportation, and wastewater treatment facilities. These expansion projects require the expenditure of significant amounts of capital, which may exceed ourresources, and involve numerous regulatory, environmental, political and legal uncertainties, including political opposition by landowners, environmentalactivists and others. There can be no assurance that we will complete these projects on schedule or at all or at the budgeted cost. Our revenues may notincrease upon the expenditure of funds on a particular project. Moreover, we may undertake expansion projects to capture anticipated future growth inproduction in a region in which anticipated production growth does not materialize or for which we are unable to acquire new customers. We may also relyon estimates of proved, probable or possible reserves in our decision to undertake expansion projects, which may prove to be inaccurate. As a result, our newfacilities and infrastructure may not be able to attract enough product to achieve our expected investment return, which could materially and adversely affectour consolidated results of operations and financial position.We may face opposition to the operation of our pipelines and facilities from various groups.We may face opposition to the operation of our pipelines and facilities from environmental groups, landowners, tribal groups, local groups and otheradvocates. Such opposition could take many forms, including organized protests, attempts to block or sabotage our operations, intervention in regulatory oradministrative proceedings involving our assets, or lawsuits or other actions designed to prevent, disrupt or delay the operation of our assets and business.For example, repairing our pipelines often involves securing consent from individual landowners to access their property; one or more landowners may resistour efforts to make needed repairs, which could lead to an interruption in the operation of the affected pipeline or facility for a period of time that issignificantly longer than would have otherwise been the case. In addition, acts of sabotage or eco-terrorism could cause significant damage or injury topeople, property or the environment or lead to extended interruptions of our operations. Any such event that interrupts the revenues generated by ouroperations, or which causes us to make significant expenditures not covered by insurance, could reduce our cash available for paying distributions to ourpartners and, accordingly, adversely affect our financial condition and the market price of our securities.Product liability claims and litigation could adversely affect our business and results of operations.Our operations are subject to all operating hazards and risks incident to handling, storing, transporting and providing customers with combustibleliquids. As a result, we are subject to product liability claims and litigation, including potential class actions, in the ordinary course of business. Any productliability claim brought against us, with or without merit, could be costly to defend and could result in an increase of our insurance premiums. Some claimsbrought against us might not be covered by our insurance policies. In addition, we have self-insured retention amounts which we would have to pay in fullbefore obtaining any insurance proceeds to satisfy a judgment or settlement and we may have insufficient reserves on our balance sheet to satisfy such self-retention obligations. Furthermore, even where the claim is covered by our insurance, our insurance coverage might be inadequate and we would have to paythe amount of any settlement or judgment that is in excess of our policy limits. Our failure to maintain adequate insurance coverage or successfully defendagainst product liability claims could materially and adversely affect our business, consolidated results of operations, financial position and cash flows.A failure in our operational systems or cyber security attacks on any of our facilities, or those of third parties, may adversely affect our financial results.Our business is dependent upon our operational systems to process a large amount of data and complex transactions. If any of our financial oroperational systems fail or have other significant shortcomings, our financial results could be adversely affected. Our financial results could also be adverselyaffected if an employee causes our systems to fail, either as a result of inadvertent error or by deliberately tampering with or manipulating our systems. Inaddition, dependence upon automated systems may further increase the risk related to operational system flaws, and employee tampering or manipulation ofthose systems will result in losses that are difficult to detect.Due to increased technology advances, we have become more reliant on technology to increase efficiency in our business. We use various systems inour financial and operations sectors, and this may subject our business to increased risks. Any future cyber security attacks that affect our facilities, ourcustomers and any financial data could have a material adverse effect on our business. In addition, cyber attacks on our customer and employee data mayresult in a financial loss, including potential fines for failure to safeguard data, and may negatively impact our reputation. Third-party systems on which werely could also suffer operational system failure. Any of these occurrences could disrupt our business, resulting in potential liability or reputational damageor otherwise have an adverse effect on our financial results.40Table of ContentsWe lease certain facilities and equipment and therefore are subject to the possibility of increased costs to retain necessary land and equipment use.We do not own all of the land on which our facilities are located, and we are therefore subject to the possibility of more onerous terms and/orincreased costs to retain necessary land use if we do not have valid rights-of-way or if our facilities are not properly located within the boundaries of suchrights-of-way. Additionally, our loss of rights, through our inability to renew right-of-way contracts or otherwise, could materially and adversely affect ourbusiness, consolidated results of operations and financial position.Additionally, certain facilities and equipment (or parts thereof) used by us are leased from third parties for specific periods, including many of ourrailcars. Our inability to renew facility or equipment leases or otherwise maintain the right to utilize such facilities and equipment on acceptable terms, or theincreased costs to maintain such rights, could have a material and adverse effect on our consolidated results of operations and cash flows.Difficulty in attracting and retaining qualified drivers could adversely affect our growth and profitability.Maintaining a staff of qualified truck drivers is critical to the success of our crude oil logistics and retail propane operations. We have in the pastexperienced difficulty in attracting and retaining sufficient numbers of qualified drivers. Regulatory requirements, including the FMCSA’s CSA initiative,and an improvement in the economy could reduce the number of eligible drivers or require us to pay more to attract and retain drivers. A shortage of qualifieddrivers and intense competition for drivers from other companies would create difficulties in increasing the number of our drivers in the event we choose toexpand our fleet of trucks. If we are unable to continue to attract and retain a sufficient number of qualified drivers, we could have difficulty meetingcustomer demands, which could materially and adversely affect our growth and profitability.If we fail to maintain an effective system of internal control, including internal control over financial reporting, we may be unable to report our financialresults accurately or prevent fraud, which would likely have a negative impact on the market price of our common units.We are subject to the public reporting requirements of the Securities Exchange Act of 1934, as amended. We are also subject to the obligation underSection 404(a) of the Sarbanes Oxley Act of 2002 to annually review and report on our internal control over financial reporting, and to the obligation underSection 404(b) of the Sarbanes Oxley Act of 2002 to engage our independent registered public accounting firm to attest to the effectiveness of our internalcontrol over financial reporting.Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud, and operate successfully as a publicly tradedpartnership. Our efforts to maintain our internal controls may be unsuccessful, and we may be unable to maintain effective internal control over financialreporting, including our disclosure controls. Any failure to maintain effective internal control over financial reporting and disclosure controls could harm ouroperating results or cause us to fail to meet our reporting obligations. These risks may be heightened after a business combination, during the phase when weare implementing our internal control structure over the recently acquired business.Given the difficulties inherent in the design and operation of internal control over financial reporting, as well as future growth of our businesses, wecan provide no assurance as to either our or our independent registered public accounting firm’s conclusions about the effectiveness of internal controls inthe future, and we may incur significant costs in our efforts to comply with Section 404. Ineffective internal controls could subject us to regulatory scrutinyand a loss of confidence in our reported financial information, which could have an adverse effect on our business and would likely have a negative effect onthe market price of our common units.An impairment of goodwill and long-lived assets could reduce our earnings.At March 31, 2018, we had goodwill and long-lived assets of $4.1 billion. Such assets are subject to impairment reviews on an annual basis, or at aninterim date if information indicates that such asset values have been impaired. Any impairment we would be required to record in our financial statementswould result in a charge to our income, which would reduce our earnings.Our business requires extensive credit risk management that may not be adequate to protect against customer nonpayment.Our credit management procedures may not fully eliminate the risk of nonpayment by our customers. We manage our credit risk exposure throughcredit analysis, credit approvals, establishing credit limits, requiring prepayments (partially or41Table of Contentswholly), requiring product deliveries over defined time periods, and credit monitoring. While we believe our procedures are effective, we can provide noassurance that bad debt write-offs in the future may not be significant and any such nonpayment problems could impact our consolidated results ofoperations and potentially limit our ability to make payments on our debt obligations or distributions to our unitholders.Our terminaling operations depend on various forms of transportation for receipt and delivery of crude oil, natural gas liquids and refined products.We own natural gas liquids and crude oil terminals and lease refined products terminals. The facilities depend on pipelines, railroads, trucktransports, and storage systems that are owned and operated by third parties. Any interruption of service on pipeline, railroad or lateral connections or adversechange in the terms and conditions of service could have a material adverse effect on our ability, and the ability of our customers, to transport product to andfrom our facilities and have a corresponding material adverse effect on our revenues. In addition, the rates charged by the interconnected pipelines fortransportation to and from our facilities impact the utilization and value of our terminals. We have historically been able to pass through the costs of pipelinetransportation to our customers. However, if competing pipelines do not have similar annual tariff increases or service fee adjustments, such increases couldaffect our ability to compete, thereby adversely affecting our revenues.Our marketing operations depend on the availability of transportation and storage capacity.Our product supply is transported and stored in facilities owned and operated by third parties. Any interruption of service on the pipeline or storagecompanies or adverse change in the terms and conditions of service could have a material adverse effect on our ability, and the ability of our customers, totransport products and have a corresponding material adverse effect on our revenues. In addition, the rates charged by the interconnected pipelines fortransportation affects the profitability of our operations.The financial results of our natural gas liquids businesses are seasonal and generally lower in the first and second quarters of our fiscal year, which mayrequire us to borrow money to make distributions to our unitholders during these quarters.The natural gas liquids inventory we have presold to customers is highest during summer months, and our cash receipts are lowest during summermonths. As a result, our cash available for distribution for the summer is much lower than for the winter. With lower cash flow during the first and secondfiscal quarters, we may be required to borrow money to pay distributions to our unitholders during these quarters. Any restrictions on our ability to borrowmoney could restrict our ability to pay the minimum quarterly distributions to our unitholders.A significant increase in fuel prices may adversely affect our transportation costs.Fuel is a significant operating expense for us in connection with the delivery of products to our customers. A significant increase in fuel prices willresult in increased transportation costs to us. The price and supply of fuel is unpredictable and fluctuates based on events we cannot control, such asgeopolitical developments, supply and demand for oil and gas, actions by oil and gas producers, war and unrest in oil producing countries and regions,regional production patterns and weather concerns. As a result, any increases in these prices may adversely affect our profitability and competitiveness.Some of our operations cross the United States/Canada border and are subject to cross-border regulation.Our cross-border activities subject us to regulatory matters, including import and export licenses, tariffs, Canadian and United States customs and taxissues, and toxic substance certifications. Such regulations include the “Short Supply Controls” of the Export Administration Act, the North American FreeTrade Agreement and the Toxic Substances Control Act. Violations of these licensing, tariff and tax reporting requirements could result in the imposition ofsignificant administrative, civil and criminal penalties.The risk of terrorism and political unrest in various energy producing regions may adversely affect the economy and the price and availability of products.An act of terror in any of the major energy producing regions of the world could potentially result in disruptions in the supply of crude oil andnatural gas, which could have a material impact on both availability and price. Terrorist attacks in the areas of our operations could negatively impact ourability to transport propane to our locations. These risks could potentially negatively impact our consolidated results of operations.42Table of ContentsWe depend on the leadership and involvement of key personnel for the success of our businesses.We have certain key individuals in our senior management who we believe are critical to the success of our business. The loss of leadership andinvolvement of those key management personnel could potentially have a material adverse impact on our business and possibly on the market value of ourcommon units.Risks Inherent in an Investment in UsOur partnership agreement limits the fiduciary duties of our general partner to our unitholders and restricts the remedies available to our unitholders foractions taken by our general partner that might otherwise be breaches of fiduciary duty.Fiduciary duties owed to our unitholders by our general partner are prescribed by law and our partnership agreement. The Delaware Revised UniformLimited Partnership Act (“Delaware LP Act”) provides that Delaware limited partnerships may, in their partnership agreements, restrict the fiduciary dutiesowed by the general partner to limited partners and the partnership. Our partnership agreement contains provisions that reduce the standards to which ourgeneral partner would otherwise be held by state fiduciary duty law. For example, our partnership agreement:•limits the liability and reduces the fiduciary duties of our general partner, while also restricting the remedies available to our unitholders foractions that, without these limitations, might constitute breaches of fiduciary duty. As a result of purchasing common units, our unitholdersconsent to some actions and conflicts of interest that might otherwise constitute a breach of fiduciary or other duties under applicable state law;•permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner. Thisentitles our general partner to consider only the interests and factors that it desires, and it has no duty or obligation to give any consideration toany interest of, or factors affecting, us, our affiliates or any limited partner. Examples include the exercise of its limited call right, its votingrights with respect to the units it owns and its determination whether or not to consent to any merger or consolidation of the Partnership;•provides that our general partner shall not have any liability to us or our unitholders for decisions made in its capacity as general partner so longas it acted in good faith, meaning our general partner subjectively believed that the decision was in, or not opposed to, the best interests of thePartnership;•generally provides that affiliated transactions and resolutions of conflicts of interest not approved by the conflicts committee and not involvinga vote of our unitholders must be on terms no less favorable to us than those generally being provided to or available from unrelated thirdparties or be “fair and reasonable” to us and that, in determining whether a transaction or resolution is “fair and reasonable,” our general partnermay consider the totality of the relationships between the parties involved, including other transactions that may be particularly favorable oradvantageous to us; and•provides that our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners for any actsor omissions unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that ourgeneral partner or those other persons acted in bad faith or engaged in fraud or willful misconduct.By purchasing a common unit, a common unitholder will become bound by the provisions of our partnership agreement, including the provisionsdescribed above.Our general partner and its affiliates have conflicts of interest with us and limited fiduciary duties to our unitholders, and they may favor their owninterests to the detriment of us and our unitholders.The NGL Energy GP Investor Group owns and controls our general partner and its 0.1% general partner interest in us. Although our general partnerhas certain fiduciary duties to manage us in a manner beneficial to us and our unitholders, the executive officers and directors of our general partner have afiduciary duty to manage our general partner in a manner beneficial to its owners. Furthermore, since certain executive officers and directors of our generalpartner are executive officers or directors of affiliates of our general partner, conflicts of interest may arise between the NGL Energy GP Investor Group and itsaffiliates, including our general partner, on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our general partner mayfavor its own interests and the interests of its affiliates over the interests of our unitholders (see “–Our partnership agreement limits the fiduciary duties of ourgeneral partner to our unitholders and restricts the remedies available to our unitholders for actions taken by our general partner that might otherwise bebreaches of fiduciary duty,” above). The risk to our unitholders due to such conflicts may arise because of the following factors, among others:43Table of Contents•our general partner is allowed to take into account the interests of parties other than us, such as members of the NGL Energy GP Investor Group,in resolving conflicts of interest;•neither our partnership agreement nor any other agreement requires owners of our general partner to pursue a business strategy that favors us;•except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval;•our general partner determines the amount and timing of asset purchases and sales, borrowings, issuance of additional partnership securities andthe creation, reduction or increase of reserves, each of which can affect the amount of cash that is distributed to our unitholders;•our general partner determines the amount and timing of any capital expenditures and whether a capital expenditure is classified as amaintenance capital expenditure, which reduces operating surplus, or an expansion capital expenditure, which does not reduce operatingsurplus. This determination can affect the amount of cash that is distributed to our unitholders and to our general partner;•our general partner determines which costs incurred by it are reimbursable by us;•our general partner may cause us to borrow funds to permit the payment of cash distributions, even if the purpose or effect of the borrowing is tomake incentive distributions;•our partnership agreement permits us to classify up to $20.0 million as operating surplus, even if it is generated from asset sales, non-workingcapital borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions to our generalpartner in respect of the general partner interest or the incentive distribution rights (“IDRs”);•our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered 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;•our general partner may exercise its right to call and purchase all of the common units not owned by it and its affiliates if they own more than80% of the common units;•our general partner controls the enforcement of the obligations that it and its affiliates owe to us;•our general partner decides whether to retain separate counsel, accountants or others to perform services for us; and•our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to ourgeneral partner’s IDRs without the approval of the conflicts committee of the board of directors of our general partner or our unitholders. Thiselection may result in lower distributions to our common unitholders in certain situations.In addition, certain members of the NGL Energy GP Investor Group and their affiliates currently hold interests in other companies in the energy andnatural resource sectors. Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other thanacting as our general partner and those activities incidental to its ownership interest in us. However, members of the NGL Energy GP Investor Group are notprohibited from engaging in other businesses or activities, including those that might be in direct competition with us. As a result, they could potentiallycompete with us for acquisition opportunities and for new business or extensions of the existing services provided by us.Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our generalpartner or any of its affiliates, including its executive officers, directors and owners. Any such person or entity that becomes aware of a potential transaction,agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any suchperson or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entitypursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or informationto us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of usand our unitholders.44Table of ContentsEven if our unitholders are dissatisfied, they have limited voting rights and are not entitled to elect our general partner or its directors.Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore,limited ability to influence management’s decisions regarding our business. Unitholders will have no right on an annual or ongoing basis to elect our generalpartner or its board of directors. The board of directors of our general partner is chosen entirely by its members and not by our unitholders. Unlike publiclytraded corporations, we will not conduct annual meetings of our unitholders to elect directors or conduct other matters routinely conducted at annualmeetings of stockholders of corporations. Furthermore, if our unitholders are dissatisfied with the performance of our general partner, they will have limitedability to remove our general partner. As a result of these limitations, the price at which the common units will trade could be diminished because of theabsence or reduction of a takeover premium in the trading price. Our partnership agreement also contains provisions limiting the ability of unitholders to callmeetings or to acquire information about our operations, as well as other provisions limiting our unitholders’ ability to influence the manner or direction ofmanagement.Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.Unitholders’ voting rights are further restricted by a provision of our partnership agreement providing that any units held by a person that owns 20%or more of any class of units then outstanding, other than our general partner, its affiliates, their direct transferees and their indirect transferees approved byour general partner (which approval may be granted in its sole discretion) and persons who acquired such units with the prior approval of our general partner,cannot vote on any matter.Our general partner interest or the control of our general partner may be transferred to a third party without the consent of our unitholders.Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without theconsent of our unitholders. Furthermore, our partnership agreement does not restrict the ability of the members of the NGL Energy GP Investor Group totransfer all or a portion of their ownership interest in our general partner to a third party. The new owner of our general partner would then be in a position toreplace the board of directors and officers of our general partner with its own designees and thereby exert significant control over the decisions made by theboard of directors and officers.The IDRs of our general partner may be transferred to a third party.Prior to the first day of the first quarter beginning after the 10th anniversary of the closing date of our IPO, a transfer of IDRs by our general partnerrequires (except in certain limited circumstances) the consent of a majority of our outstanding common units (excluding common units held by our generalpartner and its affiliates). However, after the expiration of this period, our general partner may transfer its IDRs to a third party at any time without the consentof our unitholders. If our general partner transfers its IDRs to a third party but retains its general partner interest, our general partner may not have the sameincentive to grow our partnership and increase quarterly distributions to unitholders over time as it would if it had retained ownership of its IDRs.Our general partner has a limited call right that may require our unitholders to sell their common units at an undesirable time or price.If at any time our general partner and its affiliates own more than 80% of the common units, our general partner will have the right, which it mayassign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a pricethat is not less than their then-current market price, as calculated pursuant to the terms of our partnership agreement. As a result, our unitholders may berequired to sell their common units at an undesirable time or price and may not receive any return or may receive a negative return on their investment. Ourunitholders may also incur a tax liability upon a sale of their units.Cost reimbursements to our general partner may be substantial and could reduce our cash available to make quarterly distributions to our unitholders.Prior to making any distribution on the common units, we will reimburse our general partner and its affiliates for all expenses they incur on ourbehalf, which will be determined by our general partner in its sole discretion in accordance with the terms of our partnership agreement. In determining thecosts and expenses allocable to us, our general partner is subject to its fiduciary duty, as modified by our partnership agreement, to the limited partners, whichrequires it to act in good faith. These45Table of Contentsexpenses will include all costs incurred by our general partner and its affiliates in managing and operating us. We are managed and operated by executiveofficers and directors of our general partner. The reimbursement of expenses and payment of fees, if any, to our general partner and its affiliates, will reducethe amount of cash available for distribution to our unitholders.Our partnership agreement requires that we distribute all of our available cash, which could limit our ability to grow and make acquisitions.We expect that we will distribute all of our available cash to our unitholders and will rely primarily on external financing sources, includingcommercial bank borrowings and the issuance of debt and equity securities, as well as reserves we have established to fund our acquisitions and expansioncapital expenditures. As a result, to the extent we are unable to finance growth externally, our cash distribution policy will significantly impair our ability togrow.In addition, because we distribute all of our available cash, our growth may not be as fast as that of businesses that reinvest their available cash toexpand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment ofdistributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are nolimitations in our partnership agreement or the agreements governing our indebtedness on our ability to issue additional units, including units ranking seniorto the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interestexpense, which, in turn, may impact the available cash that we have to distribute to our unitholders.We may issue additional units without the approval of our unitholders, which would dilute the interests of existing unitholders.Our partnership agreement does not limit the number of additional limited partner interests that we may issue at any time without the approval of ourunitholders. Our issuance of additional common units or other equity securities of equal or senior rank will have the following effects:•our existing unitholders’ proportionate ownership interest in us will decrease;•the amount of available cash for distribution on each unit may decrease;•the ratio of taxable income to distributions may increase;•the relative voting strength of each previously outstanding unit may be diminished; and•the market price of the common units may decline.Our general partner, without the approval of our unitholders, may elect to cause us to issue common units while also maintaining its general partnerinterest in connection with a resetting of the target distribution levels related to its IDRs. This could result in lower distributions to our unitholders.Our general partner has the right to reset the initial target distribution levels at higher levels based on our distributions at the time of the exercise ofthe reset election. Following a reset election by our general partner, the minimum quarterly distribution will be adjusted to equal the reset minimum quarterlydistribution and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterlydistribution.If our general partner elects to reset the target distribution levels, it will be entitled to receive a number of common units. The number of commonunits to be issued to our general partner will be equal to that number of common units that would have entitled their holder to an average aggregate quarterlycash distribution in the prior two quarters equal to the average of the distributions to our general partner on the IDRs in the prior two quarters. We anticipatethat our general partner would exercise this reset right to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cashdistributions per common unit without such conversion. It is possible, however, that our general partner could exercise this reset election at a time when it isexperiencing, or expects to experience, declines in the cash distributions it receives related to its IDRs and may, therefore, desire to be issued common unitsrather than retain the right to receive distributions on its IDRs based on the initial target distribution levels. As a result, a reset election may cause ourcommon unitholders to experience a reduction in the amount of cash distributions that our common unitholders would have otherwise received had we notissued new common units and general partner interests to our general partner in connection with resetting the target distribution levels.46Table of ContentsOur unitholders’ liability may not be limited if a court finds that unitholder action constitutes control of our business.A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those contractual obligations ofthe partnership that are expressly made without recourse to the general partner. Our Partnership is organized under Delaware law, and we conduct business ina number of other states. The limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not beenclearly established in some of the other states in which we do business. You could be liable for any and all of our obligations as if you were a general partnerif a court or government agency were to determine that:•we were conducting business in a state but had not complied with that particular state’s partnership statute; or•a unitholder’s right to act with other unitholders to remove or replace our general partner, to approve some amendments to our partnershipagreement or to take other actions under our partnership agreement constitute “control” of our business.Our unitholders may have liability to repay distributions that were wrongfully distributed to them.Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of theDelaware LP Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets.Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and whoknew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Substituted limitedpartners are liable both for the obligations of the assignor to make contributions to the partnership that were known to the substituted limited partner at thetime it became a limited partner and for those obligations that were unknown if the liabilities could have been determined from the partnership agreement.Neither liabilities to partners on account of their partnership interests nor liabilities that are nonrecourse to the partnership are counted for purposes ofdetermining whether a distribution is permitted. For the purpose of determining the fair value of the assets of a limited partnership, the Delaware LP Actprovides that the fair value of property subject to liability for which recourse of creditors is limited shall be included in the assets of the limited partnershiponly to the extent that the fair value of that property exceeds the nonrecourse liability.The 10.75% Class A Convertible Preferred Units (“Class A Preferred Units”) and 9.00% Class B Fixed-to-Floating Rate Cumulative RedeemablePerpetual Preferred Units (“Class B Preferred Units”) (collectively the “Preferred Units”) give the holders thereof liquidation and distribution preferencesover our common unitholders.In June 2016, we issued 19,942,169 Class A Preferred Units and in June 2017, we issued 8,400,000 Class B Preferred Units, which rank senior to thecommon units with respect to distribution rights and rights upon liquidation. Subject to certain exceptions, as long as any Preferred Units remainoutstanding, we may not declare any distribution on our common units unless all accumulated and unpaid distributions have been declared and paid on thePreferred Units. In the event of our liquidation, winding-up or dissolution, the holders of the Preferred Units would have the right to receive proceeds fromany such transaction before the holders of the common units. The payment of the liquidation preference could result in common unitholders not receivingany consideration if we were to liquidate, dissolve or wind up, either voluntarily or involuntarily. Additionally, the existence of the liquidation preferencemay reduce the value of the common units, make it harder for us to sell common units in offerings in the future, or prevent or delay a change of control.The Class A Preferred Units give the holders thereof certain rights relating to our business and management, and the ability to convert such units into ourcommon units, potentially causing dilution to our common unitholders.In connection with the issuance of the Class A Preferred Units, we entered into an agreement with Oaktree Capital Management L.P. (“Oaktree”)pursuant to which we granted them the right to appoint one member to the board of directors of our general partner. In addition, the holders of the Class APreferred Units have the right to vote, under certain conditions, on an as-converted basis with our common unitholders on matters submitted to a unitholdervote. Also, as long as any Class A Preferred Units are outstanding, subject to certain exceptions, the affirmative vote or consent of the holders of at least amajority of the outstanding Class A Preferred Units, voting together as a separate class, will be necessary for effecting or validating, among other things: (i)any action to be taken that adversely affects any of the rights, preferences or privileges of the Class A Preferred Units, (ii) amending the terms of the Class APreferred Units, (iii) the issuance of any additional Class A Preferred Units or equity security senior in right of distribution or in liquidation to the Class APreferred Units, (iv) any issuance of preferred equity securities by any of our consolidated controlled subsidiaries of any issued or authorized amount of, anyspecific class or series of securities, (v) any issuance by us of parity units, subject to certain exceptions and (vi) the ability to incur funded indebtedness forborrowed money if pro forma for such incurrence, the leverage ratio (as defined in the Credit47Table of ContentsAgreement) would exceed 5.50. These restrictions may adversely affect our ability to finance future operations or capital needs or to engage in other businessactivities.Furthermore, the conversion of the Class A Preferred Units into common units, as early as three years from the issuance date of the Class A PreferredUnits, may cause substantial dilution to holders of the common units. Because the board of directors of our general partner is entitled to designate the powersand preferences of Class A Preferred Units without a vote of our unitholders, subject to New York Stock Exchange rules and regulations, our unitholders willhave no control over what designations and preferences our future preferred units, if any, will have.The issuance of common units upon exercise of the warrants may cause dilution to existing common unitholders and may place downward pressure on thetrading price of our common units.In connection with our issuance of Class A Preferred Units in June 2016, we issued warrants exercisable into a maximum of 4,375,112 common units,with an exercise price of $0.01 per common unit. One-third of the warrants are exercisable beginning on or after the first anniversary of the original issue date,another one-third of the warrant units from and after the second anniversary of the original issue date and the final one-third may be converted from and afterthe third anniversary. The future exercise of the warrants by the holders of those securities may cause a reduction in the relative voting power and percentageownership interests of our other common unitholders, and may place downward pressure on the trading price of our common units.Tax Risks to Common UnitholdersOur tax treatment depends on our status as a partnership for federal income tax purposes. We could lose our status as a partnership for a number ofreasons, including not having enough “qualifying income.” If the Internal Revenue Service (“IRS”) were to treat us as a corporation for federal incometax purposes, our cash available for distribution to our unitholders would be substantially reduced.The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federalincome tax purposes. We have not requested, and do not plan to request, a ruling from the IRS with respect to our treatment as a partnership for federalincome tax purposes.Despite the fact that we are a limited partnership under Delaware law, a publicly traded partnership such as us will be treated as a corporation forfederal income tax purposes unless, for each taxable year, 90% or more of its gross income is “qualifying income” under Section 7704 of the InternalRevenue Code of 1986, as amended (the “Internal Revenue Code”). “Qualifying income” includes income and gains derived from the exploration,development, production, processing, transportation, storage and marketing of natural gas, natural gas products, and crude oil or other passive types ofincome such as certain interest and dividends and gains from the sale or other disposition of capital assets held for the production of income that otherwiseconstitutes qualifying income. Although we do not believe based upon our current operations that we are treated as a corporation, we could be treated as acorporation for federal income tax purposes or otherwise subject to taxation as an entity if our gross income is not properly classified as qualifying income,there is a change in our business or there is a change in current law.If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate,which is currently 21% (changed from 35% under the recently enacted tax reform law), and would likely pay state and local income tax at varying rates.Distributions to our unitholders would generally be taxed again as corporate dividends (to the extent of our current and accumulated earnings and profits),and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cashavailable for distribution to our unitholders would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction inthe anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the market value of our common units.Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as acorporation or otherwise subjects us to entity-level taxation for federal income tax purposes, the minimum quarterly distribution amount and the targetdistribution amounts may be adjusted to reflect the impact of that law on us.48Table of ContentsOur 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 businessduring our taxable year. However, under the Tax Cuts and Jobs Act of 2017 (the “Act”) signed into law by the President of the United States on December 22,2017, beginning in tax year 2018, the deductibility of net interest expense is limited to 30% of our adjusted taxable income. For tax years beginning afterDecember 31, 2017 and before January 1, 2022, the Act calculates adjusted taxable income using an EBITDA-based calculation. For tax years beginningJanuary 1, 2022 and thereafter, the calculation of adjusted taxable income will not add back depreciation or amortization. Any disallowed business interestexpense is then generally carried forward as a deduction in a succeeding taxable year at the partner level. These limitations might cause interest expense to bededucted by our unitholders in a later period than recognized in the GAAP financial statements.If we were subjected to a material amount of additional entity-level taxation by individual states, it would reduce our cash available for distribution to ourunitholders.Changes in current state law may subject us to additional entity-level taxation by individual states. Because of widespread state budget deficits andother reasons, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and otherforms of taxation. Imposition of any such taxes may substantially reduce the cash available for distribution to our unitholders. Our partnership agreementprovides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to entity-level taxation, the minimum quarterlydistribution 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 common units could be subject to potential legislative, judicial or administrativechanges and differing interpretations, possibly on a retroactive basis.The present income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified byadministrative, legislative or judicial interpretation at any time. For example, from time to time, members of Congress propose and consider substantivechanges to the existing United States federal income tax laws that affect the tax treatment of publicly traded partnerships, including as a result of anyfundamental tax reform.We are unable to predict whether any such change or other proposals will ultimately be enacted or will affect our tax treatment. Any modification tothe income tax laws and interpretations thereof may or may not be applied retroactively and could, among other things, cause us to be treated as a corporationfor federal income tax purposes or otherwise subject us to entity-level taxation. Moreover, such modifications and change in interpretations may affect orcause us to change our business activities, affect the tax considerations of an investment in us, change the character or treatment of portions of our incomeand adversely affect an investment in our common units. Although we are unable to predict whether any of these changes, or other proposals, will ultimatelybe enacted, any such changes could negatively impact the value of an investment in our common units.If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contestwill reduce our cash available for distribution 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 adoptpositions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions wetake and such positions may not ultimately be sustained. A court may not agree with some or all of the positions we take. Any contest with the IRS maymaterially and adversely impact the market for our common units and the price at which they trade. In addition, our costs of any contest with the IRS will beborne indirectly by our unitholders and our general partner because the costs will reduce our cash available for distribution.49Table of ContentsIf the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it may collect any resulting taxes (including anyapplicable penalties and interest) directly from us, in which case our cash available for distribution to our unitholders could be substantially reduced.Pursuant to the Bipartisan Budget Act of 2015, if the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, itmay collect any resulting taxes (including any applicable penalties and interest) directly from us. We will generally have the ability to shift any such taxliability to our general partner and our unitholders in accordance with their interests in us during the year under audit, but there can be no assurance that wewill be able to do so under all circumstances. If we are required to make payments of taxes, penalties and interest resulting from audit adjustments, our cashavailable for distribution to our unitholders could be substantially reduced.Our unitholders will be required to pay taxes on their share of our income even if they do not receive any cash distributions from us.Because we expect to be treated as a partnership for United States federal income tax purposes, our unitholders will be treated as partners to whomwe will allocate taxable income that could be different in amount than the cash we distribute, our unitholders will be required to pay any federal income taxesand, in some cases, state and local income taxes on their share of our taxable income even if they receive no cash distributions from us. Our unitholders maynot receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability that results from that income.Tax gain or loss on the disposition of our common units could be more or less than expected.If unitholders sell their common units, they will recognize a gain or loss equal to the difference between the amount realized and their tax basis inthose common units. Because distributions in excess of the unitholder’s allocable share of our net taxable income decrease the unitholder’s tax basis in theircommon units, the amount, if any, of such prior excess distributions with respect to the units the unitholder sells will, in effect, become taxable income to theunitholder if they sell such units at a price greater than their tax basis in those units, even if the price they receive is less than their original cost. Furthermore,a substantial portion of the amount realized on any sale of common units, whether or not representing gain, may be taxed as ordinary income due to potentialrecapture items, including depreciation recapture. In addition, because the amount realized includes a unitholder’s share of our nonrecourse liabilities, if aunitholder sell units, they may incur a tax liability in excess of the amount of cash they receive from the sale.Tax exempt entities and non-United States persons face unique tax issues from owning our common units that may result in adverse tax consequences tothem.Investment in common units by tax exempt entities, such as employee benefit plans, individual retirement accounts (“IRAs”), Keogh plans and otherretirement plans and non-United States persons raises issues unique to them. For example, virtually all of our income allocated to organizations that areexempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them.Distributions to non-United States persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-United States personswill be required to file United States federal income tax returns and pay tax on their share of our taxable income. If you are a tax exempt entity or a non-United States person, you should consult your tax advisor before investing in our common units.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 adversely affect the market 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. Any position we take that is inconsistent with applicable TreasuryRegulations may have to be disclosed on our federal income tax return. This disclosure increases the likelihood that the IRS will challenge our positions andpropose adjustments to some or all of our unitholders. A successful IRS challenge to those positions could adversely affect the amount of tax benefitsavailable to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from the sale of common units and could have anegative impact on the market value of our common units or result in audit adjustments to tax returns of unitholders.We have subsidiaries that are treated as corporations for federal income tax purposes and subject to corporate level income taxes.We conduct a portion of our operations through subsidiaries that are corporations for federal income tax purposes. We may elect to conductadditional operations in corporate form in the future. Our corporate subsidiaries will be subject to50Table of Contentscorporate level tax, which will reduce the cash available for distribution to us and, in turn, to our unitholders. If the IRS or other state or local jurisdictionswere to successfully assert that our corporate subsidiaries have more tax liability than we anticipate or legislation was enacted that increased the corporate taxrate, our cash available for distribution to our unitholders would be further reduced.We prorate our items of income, gain, loss and deduction for United States federal income tax purposes between transferors and transferees of our unitseach month based on the ownership of our units 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 this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based on 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 U.S. Department of the Treasury recentlyadopted final Treasury Regulations allowing a similar monthly simplifying convention for taxable years beginning on or after August 3, 2015. However,such regulations do not specifically authorize all aspects of the proration method we have adopted. If the IRS were to challenge our proration method, wemay be required to change the allocation of items of income, gain, loss and deduction among our unitholders.A unitholder whose units are loaned to a “short seller” to effect a short sale of units may be considered as having disposed of those common units. If so,such unitholder would no longer be treated for federal income tax purposes as a partner with respect to those common units during the period of the loanand may recognize a gain or loss from the disposition.Because a unitholder whose units are loaned to a “short seller” to effect a short sale of units may be considered as having disposed of those commonunits, the unitholder would no longer be treated for federal income tax purposes as a partner with respect to those units during the period of the loan to theshort seller and the unitholder may recognize a gain or loss from the disposition. Moreover, during the period of the loan to the short seller, any of ourincome, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as tothose units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loanto a short seller are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit theirbrokers from borrowing their units.We have adopted certain valuation methodologies and monthly conventions for United States federal income tax purposes that may result in a shift ofincome, gain, loss and deduction between our general partner and our unitholders. The IRS may challenge this treatment, which could adversely affect thevalue of our common units.When we issue additional units or engage in certain other transactions, we will determine the fair market value of our assets and allocate anyunrealized gain or loss attributable to our assets to the capital accounts of our unitholders and our general partner. Our methodology may be viewed asunderstating the value of our assets. In that case, there may be a shift of income, gain, loss and deduction between certain unitholders and the general partner,which may be unfavorable to such unitholders. Moreover, under our current valuation methods, subsequent purchasers of common units may have a greaterportion of their Internal Revenue Code Section 743(b) adjustment allocated to our tangible assets and a lesser portion allocated to our intangible assets. TheIRS may challenge our valuation methods, or our allocation of the Internal Revenue Code Section 743(b) adjustment attributable to our tangible andintangible assets, and allocations of taxable income, gain, loss and deduction between the 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 ourunitholders. It also could affect the amount of taxable gain from our unitholders’ sale of common units and could have a negative impact on the value of thecommon units or result in audit adjustments to our unitholders’ tax returns without the benefit of additional deductions.There are limits on the deductibility of our losses that may adversely affect our unitholders.There are a number of limitations that may prevent unitholders from using their allocable share of our losses as a deduction against unrelatedincome. In cases where our unitholders are subject to the passive loss rules (generally, individuals and closely held corporations), any losses generated by uswill only be available to offset our future income and cannot be used to offset income from other activities, including other passive activities or investments.Unused losses may be deducted when the unitholder disposes of its entire investment in us in a fully taxable transaction with an unrelated party. Aunitholder’s share of our net passive income may be offset by unused losses from us carried over from prior years but not by losses from other passiveactivities, including losses from other publicly traded partnerships. Other limitations that may further restrict the51Table of Contentsdeductibility of our losses by a unitholder include the at-risk rules and the prohibition against loss allocations in excess of the unitholder’s tax basis in itsunits.Purchasers of our common units may become subject to state and local taxes and return filing requirements in jurisdictions where we operate or own oracquire properties.In addition to federal income taxes, holders of our common units are subject to other taxes, including foreign, state and local income taxes,unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or ownor control property now or in the future. Holders of our common units are required to file foreign, state and local income tax returns and pay state and localincome taxes in some or all of these various jurisdictions and may be subject to penalties for failure to comply with those requirements. We own assets andconduct business in a number of states, most of which impose a personal income tax on individuals. Most of these states also impose an income tax oncorporations and other entities. As we make acquisitions or expand our business, we may own or control assets or conduct business in additional states thatimpose a personal income tax.Item 1B. Unresolved Staff CommentsNone.Item 2. PropertiesWe believe that we have satisfactory title or valid rights to use all of our material properties. Although some of these properties are subject toliabilities and leases, liens for taxes not yet due and payable, encumbrances securing payment obligations under non-compete agreements entered into inconnection with acquisitions and other encumbrances, easements and restrictions, we do not believe that any of these burdens will materially interfere withour continued use of these properties in our business, taken as a whole. Our obligation under our revolving credit facility is secured by liens and mortgageson substantially all of our real and personal property.Other than as described below, we believe that we have all required material approvals, authorizations, orders, licenses, permits, franchises andconsents of, and have obtained or made all required material registrations, qualifications and filings with, the various state and local governmental andregulatory authorities that relate to ownership of our properties or the operations of our business.One of our facilities is operating with all but one of the required permits, as the state of Wyoming has not yet developed a process for issuing permitsof this type. We believe that the permit will ultimately be granted, but we are unable to determine the timing of any action by the state of Wyoming.Our corporate headquarters are in Tulsa, Oklahoma and are leased. We also lease corporate offices in Denver, Colorado and Houston, Texas.For additional information regarding our properties and the reportable segments in which they are used, see Part I, Item 1–“Business.”Item 3. Legal ProceedingsWe are involved from time to time in various legal proceedings and claims arising in the ordinary course of business.

Prior to May 12, 2011, our common units were not listed on any exchange or traded in any public market. At May 25, 2018, there wereapproximately 150 common unitholders of record which does not include unitholders for whom common units may be held in “street name.”The following table summarizes the high and low sales prices per common unit for the periods indicated as reported on the New York StockExchange Composite Transactions tape, and the amount of cash distributions paid per common unit. Price Range Cash High Low Distribution2018 Fiscal Year Fourth Quarter $17.65 $10.00 $0.3900Third Quarter $14.75 $10.07 $0.3900Second Quarter $14.78 $8.57 $0.3900First Quarter $23.19 $11.53 $0.39002017 Fiscal Year Fourth Quarter $25.80 $20.56 $0.3900Third Quarter $21.50 $14.65 $0.3900Second Quarter $20.00 $16.75 $0.3900First Quarter $20.06 $7.10 $0.3900Cash Distribution PolicyAvailable CashOur partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash (as defined in ourpartnership agreement) to unitholders as of the record date. Available cash for any quarter generally consists of all cash on hand at the end of that quarter, lessthe amount of cash reserves established by our general partner, to (i) provide for the proper conduct of our business, (ii) comply with applicable law, any ofour debt instruments or other agreements, and (iii) provide funds for distributions to our unitholders and to our general partner for any one or more of the nextfour quarters.General Partner InterestOur general partner is entitled to 0.1% of all quarterly distributions that we make prior to our liquidation. Our general partner has the right, but notthe obligation, to contribute a proportionate amount of capital to us to maintain its 0.1% general partner interest. Our general partner’s interest in ourdistributions may be reduced if we issue additional limited partner units in the future (other than the issuance of common units upon a reset of the IDRs (asdefined herein)) and our general partner does not contribute a proportionate amount of capital to us to maintain its 0.1% general partner interest.Incentive Distribution RightsThe general partner will also receive, in addition to distributions on its 0.1% general partner interest, additional distributions based on the level ofdistributions to the limited partners. These distributions are referred to as “incentive distributions” or “IDRs.” Our general partner currently holds the IDRs,but may transfer these rights separately from its general partner interest, subject to restrictions in our partnership agreement.The following table illustrates the percentage allocations of available cash from operating surplus between our unitholders and our general partnerbased on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest In Distributions” are the percentage interests ofour general partner and our unitholders in any available53Table of Contentscash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit,” untilavailable cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for our unitholders andour general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterlydistribution.

Management’s Discussion and Analysis of Financial Condition and Results of OperationsOverviewWe are a Delaware limited partnership (“we,” “us,” “our,” or the “Partnership”) formed in September 2010. NGL Energy Holdings LLC serves as ourgeneral partner. On May 17, 2011, we completed our initial public offering (“IPO”). Subsequent to our IPO, we significantly expanded our operations throughnumerous acquisitions as discussed in Part I, Item 1–“Business–Acquisitions.” At March 31, 2018, our operations include:•Crude Oil Logistics•Water Solutions•Liquids•Retail Propane•Refined Products and RenewablesCrude Oil LogisticsOur Crude Oil Logistics segment purchases crude oil from producers and transports it to refineries or for resale at pipeline injection stations, storageterminals, barge loading facilities, rail facilities, refineries, and other trade hubs, and provides storage, terminaling, trucking, marine and pipelinetransportation services through its owned assets.Most of our contracts to purchase or sell crude oil are at floating prices that are indexed to published rates in active markets such as Cushing,Oklahoma. We attempt to reduce our exposure to price fluctuations by using back-to-back physical contracts whenever possible. When back-to-backphysical contracts are not optimal, we enter into financially settled derivative contracts as economic hedges of our physical inventory, physical sales andphysical purchase contracts. We use our transportation assets to move crude oil from the wellhead to the highest value market. Spreads between crude oilprices in different markets can fluctuate, which may expand or limit our opportunity to generate margins by transporting crude oil to different markets.The following table summarizes the range of low and high crude oil spot prices per barrel of NYMEX West Texas Intermediate Crude Oil at Cushing,Oklahoma for the periods indicated and the prices at period end: Crude Oil Spot Price Per BarrelYear Ended March 31, Low High At Period End2018 $42.53 $66.14 $64.942017 $35.70 $54.45 $50.602016 $26.21 $61.43 $38.34We believe volatility in commodity prices will continue, and our ability to adjust to and manage this volatility may impact our financial results.Our Crude Oil Logistics segment generated operating income of $122.9 million during the year ended March 31, 2018, which included a gain of$108.6 million on the sale of our previously held 50% interest in Glass Mountain Pipeline, LLC (“Glass Mountain”). Our Crude Oil Logistics segmentgenerated an operating loss of $17.5 million during the year ended March 31, 2017.Water SolutionsOur Water Solutions segment provides services for the treatment and disposal of wastewater generated from crude oil and natural gas production andfor the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, our Water Solutionssegment sells the recovered hydrocarbons that result from performing these services.Our water processing facilities are strategically located near areas of high crude oil and natural gas production. A significant factor affecting theprofitability of our Water Solutions segment is the extent of exploration and production in the areas near our facilities, which is generally based uponproducers’ expectations about the profitability of drilling new wells. The56Table of Contentsprimary customer of our Wyoming facility has committed to deliver a specified minimum volume of water to our facility under a long-term contract. Theprimary customers of our Colorado facilities have committed to deliver all wastewater produced at wells within the DJ Basin to our facilities. One customer inTexas has committed to deliver a minimum volume of 40,000 barrels of wastewater per day to our facilities. Most customers of our other facilities are notunder volume commitments, although many of our facilities have acreage dedications or are connected to producer facilities by pipeline.Our Water Solutions segment generated an operating loss of $24.2 million during the year ended March 31, 2018. Our Water Solutions segmentgenerated operating income of $44.6 million during the year ended March 31, 2017, which included an adjustment of $124.7 million to the previouslyrecorded $380.2 million estimated goodwill impairment charge recorded during the three months ended March 31, 2016 (see Note 6 to our consolidatedfinancial statements included in this Annual Report).LiquidsOur Liquids segment purchases propane, butane, and other products from refiners, processing plants, producers, and other parties, and sells theproducts to retailers, wholesalers, refiners, and petrochemical plants throughout the United States and in Canada. Our Liquids segment owns 21 terminalsthroughout the United States and a salt dome storage facility joint venture in Utah, operates a fleet of leased railcars, and leases underground storagecapacity. See Note 15 to our consolidated financial statements included in this Annual Report for a discussion of the joint venture of our Sawtooth NGLCaverns, LLC (“Sawtooth”) business. We attempt to reduce our exposure to price fluctuations by using back-to-back physical contracts and pre-saleagreements that allow us to lock in a margin on a percentage of our winter volumes. We also enter into financially settled derivative contracts as economichedges of our physical inventory, physical sales and physical purchase contracts.Our wholesale Liquids business is a “cost-plus” business that can be affected by both price fluctuations and volume variations. We establish ourselling price based on a pass-through of our product supply, transportation, handling, storage, and capital costs plus an acceptable margin. The margin werealize in our wholesale Liquids business is substantially less on a per gallon basis than the margin we realize in our Retail Propane business.Weather conditions and gasoline blending can have a significant impact on the demand for propane and butane, and sales volumes and prices aretypically higher during the colder months of the year. Consequently, our revenues, operating profits, and operating cash flows are typically lower in the firstand second quarters of our fiscal year.The following table summarizes the range of low and high propane spot prices per gallon at Conway, Kansas, and Mt. Belvieu, Texas, two of ourmain pricing hubs, for the periods indicated and the prices at period end: Conway, Kansas Mt.

Our Liquids segment generated operating income of $43.3 million duringthe year ended March 31, 2017.Retail PropaneOur Retail Propane segment is a “cost-plus” business that sells propane, distillates, equipment and supplies to end users consisting of residential,agricultural, commercial, and industrial customers and to certain resellers in 21 states and the District of Columbia. Our Retail Propane segment purchases themajority of its propane from our Liquids segment. See Note 15 to our consolidated financial statements included in this Annual Report for a discussion of thesale of a portion of our Retail Propane segment. Our Retail Propane segment generates margins based on the difference between the wholesale cost of aproduct and the selling price of the product in the retail markets. These margins fluctuate over time due to supply and demand conditions. Weatherconditions can have a significant impact on our sales volumes and prices, as a large portion of our sales are to residential customers who purchase propaneand distillates for home heating purposes.A significant factor affecting the profitability of our Retail Propane segment is our ability to maintain our product margin. Product margin is thedifference between our sales prices and our total product costs, including transportation and storage. We monitor wholesale propane prices daily and adjustour retail prices accordingly. We believe volatility in commodity prices will continue, and our ability to adjust to and manage this volatility may impact ourfinancial results.The Retail Propane business is both weather-sensitive and subject to seasonal volume variations due to propane’s primary use as a heating source inresidential and commercial buildings and for agricultural purposes. Consequently, our revenues, operating profits, and operating cash flows are typicallylower in the first and second quarters of our fiscal year.Our Retail Propane segment generated operating income of $155.6 million during the year ended March 31, 2018, which included a gain of $89.3million on the sale of a portion of our Retail Propane segment. Our Retail Propane segment generated operating income of $49.3 million during the yearended March 31, 2017.Refined Products and RenewablesOur Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations, purchases refined petroleumand renewable products primarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedules them for delivery at various locationsthroughout the country. In addition, in certain storage locations, our Refined Products and Renewables segment may also purchase unfinished gasolineblending components for subsequent blending into finished gasoline to supply our marketing business as well as third parties. We sell our products tocommercial and industrial end users, independent retailers, distributors, marketers, government entities, and other wholesalers of refined petroleum products.We sell our products at terminals owned by third parties.The following table summarizes the range of low and high Gulf Coast gasoline spot prices per barrel using NYMEX gasoline prompt-month futuresfor the periods indicated and the prices at period end: Gasoline Spot Price Per BarrelYear Ended March 31, Low High At Period End2018 $59.24 $89.88 $84.752017 $53.44 $71.40 $71.402016 $37.75 $90.15 $59.91The following table summarizes the range of low and high diesel spot prices per barrel using NYMEX ULSD prompt-month futures for the periodsindicated and the prices at period end: Diesel Spot Price Per BarrelYear Ended March 31, Low High At Period End2018 $57.32 $89.71 $85.192017 $45.13 $71.58 $66.092016 $36.36 $84.68 $49.76Our Refined Products and Renewables segment generated operating income of $56.7 million during the year ended March 31, 2018.

The opportunity to generate revenues in our Crude OilLogistics business is heavily influenced by the volume of crude oil being produced. Crude oil prices declined sharply during the period from July 2014through February 2016. Crude oil prices have rebounded and at March 31, 2018, the spot price for NYMEX West Texas Intermediate Crude Oil at Cushing,Oklahoma was $64.94 per barrel. While crude oil production in the United States has been strong in recent years, a sharp decline in crude oil prices couldreduce the incentive for producers to expand production. Low crude oil prices could result in declines in crude oil production and may adversely impactvolumes and margins in our Crude Oil Logistics business. Crude oil price declines have had an adverse impact on many participants in the energy markets,and the inherent risk of customer or counterparty nonperformance is higher when crude oil prices are low or in decline.From January 2015 to January 2018, crude oil markets were in contango, a condition in which forward crude oil prices are greater than spot prices.Our Crude Oil Logistics business benefits when the market is in contango, as increasing prices result in inventory holding gains during the time betweenwhen we purchase inventory and when we sell it. In addition, we are59Table of Contentsable to better utilize our storage assets when contango markets justify storing barrels. Beginning in February 2018, crude oil markets have shifted to beingflat to backwardated, a condition in which forward crude oil prices are lower than spot prices. When markets are backwardated, falling prices typically havean unfavorable impact on our margins.Our opportunity to generate revenues in our Water Solutions business is based on the level of production of natural gas and crude oil in the areaswhere our facilities are located. As described above, crude oil prices declined sharply since July 2014 but have increased since March 31, 2016. Also, drillingrigs and production have increased since March 31, 2016, particularly in the Permian and DJ Basins which has positively impacted the volumes of our WaterSolutions business (during the three months ended March 31, 2018 we processed 761,000 barrels of wastewater per day, compared to 536,000 barrels ofwastewater per day during the three months ended March 31, 2017). A portion of the revenues in our Water Solutions business is generated from the sale ofhydrocarbons that we recover when processing wastewater. These recovered hydrocarbon revenues have increased due primarily to an increase in the volumeof wastewater processed, an increase in the amount of hydrocarbons per barrel of wastewater processed and an increase in crude oil prices, which have resultedin higher per-barrel revenues for our Water Solutions business.An important element of our Refined Products and Renewables segment relates to the marketing of refined products in the Southeast and East Coastregions. We purchase product in the Gulf Coast, transport the product on third party pipelines, and sell the product at terminals owned by third parties. Mostof the contracts with these customers are one year in duration, with pricing indexed to prices in the Gulf Coast at the date of sale plus a specified differential.To operate this business we maintain inventory in transit on third party pipelines and at destination terminals where we sell the product. The value of thisinventory will increase or decrease as market prices change. In order to mitigate this risk, we enter into futures contracts, which are only available based onNew York Harbor pricing. Because our contracts are indexed to Gulf Coast prices and our futures contracts are based on New York Harbor prices, the futurescontracts are not a perfect hedge against our inventory holding risk. During any given period, spreads between prices in the Gulf Coast and New York Harborcould narrow or widen, which could reduce the effectiveness of the futures contracts as a hedge of the inventory holding risk. The tenor of these futurescontracts, which are typically six months to one year in duration at inception, can also contribute to volatility in earnings among individual quarters within afiscal year.During the year ended March 31, 2018, prices for refined products increased. Gulf Coast prices, on which our sales contracts are based, increased lessthan the New York Harbor prices, on which our futures contracts are based, which had an unfavorable impact on our cost of sales. Based on historicalexperience, we generally expect the spreads between Gulf Coast and New York Harbor prices to be more consistent over the course of a contract year thanduring any individual quarter within the year, and that we should expect more volatility in cost of sales among quarters within a fiscal year than we wouldexpect during a full fiscal year.SeasonalitySeasonality impacts our Liquids, Retail Propane and Refined Products and Renewables segments. A large portion of our Retail Propane business isin the residential market where propane is used primarily for home heating purposes. Consequently, for our Liquids and Retail Propane businesses, revenues,operating profits and operating cash flows are generated mostly in the third and fourth quarters of our fiscal year. The seasonal motor fuel blend during thethird quarter of our fiscal year impacts the value of our gasoline inventory in our Refined Products and Renewables business and also represents a periodwhen we build inventory into our system. We borrow under our Revolving Credit Facility to supplement our operating cash flows during the periods inwhich we are building inventory. See “–Liquidity, Sources of Capital and Capital Resource Activities–Cash Flows.”Recent DevelopmentsTransactions during the Three Months Ended March 31, 2018Repurchases of Senior Unsecured NotesDuring the three months ended March 31, 2018, we repurchased $7.4 million of the 2019 Notes (as defined herein), $40.6 million of the 2023 Notes(as defined herein) and $23.4 million of the 2025 Notes (as defined herein). See Note 8 to our consolidated financial statements included in this AnnualReport for further discussion on the repurchases.60Table of ContentsCredit AgreementOn March 6, 2018, we amended our Credit Agreement. In the amendment, the lenders consented to, subject to the consummation of the initialSawtooth disposition, release each Sawtooth entity from its guaranty and other obligations under the loan documents. In return, the Partnership agreed to usethe net proceeds of each Sawtooth disposition to pay down existing indebtedness no later than five business days after the consummation of such Sawtoothdisposition.Subsequent EventsOn May 24, 2018, we amended our Credit Agreement to, among other things, modify our interest coverage ratio financial covenant for periodsbeginning March 31, 2018 and thereafter and to add a total leverage indebtedness ratio covenant, to be measured beginning March 31, 2019. Additionally,the amendment specifies that, should our leverage ratio be greater than 4.00 to 1 with respect to the quarter ended September 30, 2018, commitments underour Expansion Capital Facility will be decreased, immediately and permanently by $100.0 million.See Note 8 to our consolidated financial statements included in this Annual Report for a further description of our Credit Agreement.AcquisitionsAs discussed below, we completed numerous acquisitions during the years ended March 31, 2018 and 2017. These acquisitions impact thecomparability of our results of operations between our current and prior fiscal years.During the year ended March 31, 2018, in our Water Solutions segment, we acquired the remaining 50% ownership interest in NGL Solids Solutions,LLC, and in our Retail Propane segment, we acquired seven retail propane businesses and certain assets from an equity method investee. See Note 4 andNote 13 to our consolidated financial statements included in this Annual Report for a further discussion.During the year ended March 31, 2017, we acquired:•three water solutions facilities;•the remaining 25% ownership interest in three water solutions facilities;•an additional 24.5% interest in NGL Water Pipelines, LLC;•the remaining 65% ownership interest in Grassland Water Solutions, LLC (“Grassland”), in which we subsequently sold 100% of our interest;•four retail propane businesses; and•certain natural gas liquids facilities.Subsequent EventsSee Note 17 to our consolidated financial statements included in this Annual Report for a further discussion of the acquisitions that occurredsubsequent to March 31, 2018.DispositionsSale of a Portion of Retail Propane BusinessOn March 30, 2018, we sold a portion of our Retail Propane segment to DCC LPG for net proceeds of $212.4 million in cash at closing, and recordeda gain on disposal of $89.3 million during the year ended March 31, 2018. The Retail Propane businesses subject to this transaction consisted of ouroperations across the Mid-Continent and Western portions of the United States, including three of the seven retail propane businesses we acquired during theyear ended March 31, 2018. We retained our Retail Propane businesses located in the Eastern, mid-Atlantic and Southeastern sections of the United States.See Note 15 to our consolidated financial statements included in this Annual Report for a further discussion.61Table of ContentsAs this sale transaction did not represent a strategic shift that will have a major effect on our operations or financial results, operations related to thisportion of our Retail Propane segment have not been classified as discontinued operations.Sawtooth Joint VentureOn March 30, 2018, we completed the transaction to form a joint venture with Magnum Liquids, LLC, a portfolio company of Haddington VenturesLLC, along with Magnum Development, LLC and other Haddington-sponsored investment entities (collectively “Magnum”) to focus on the storage ofnatural gas liquids and refined products by combining our Sawtooth salt dome storage facility with Magnum’s refined products rights and adjacent leasehold.Magnum acquired an approximately 28.5% interest in Sawtooth from us, in exchange for consideration consisting of a cash payment of approximately $37.6million (excluding working capital) and the contribution of certain refined products rights and adjacent leasehold. The disposition of this interest wasaccounted for as an equity transaction, no gain or loss was recorded and the carrying value of the noncontrolling interest was adjusted to reflect the change inownership interest of the subsidiary. We own approximately 71.5% of the joint venture; and within the next three years, Magnum has options to acquire ourremaining interest for an additional $182.4 million. See Note 15 to our consolidated financial statements included in this Annual Report for a furtherdiscussion.Sale of Interest in Glass MountainOn December 22, 2017, we sold our previously held 50% interest in Glass Mountain for net proceeds of $292.1 million and recorded a gain ondisposal of $108.6 million during the three months ended December 31, 2017. See Note 2 to our consolidated financial statements included in this AnnualReport for a further discussion.As this sale transaction did not represent a strategic shift that will have a major effect on our operations or financial results, operations related to thisportion of our Crude Oil Logistics segment have not been classified as discontinued operations.Subsequent EventsSee Note 17 to our consolidated financial statements included in this Annual Report for a further discussion of the dispositions that occurredsubsequent to March 31, 2018.62Table of ContentsSegment Operating Results for the Years Ended March 31, 2018 and 2017Crude Oil Logistics The following table summarizes the operating results of our Crude Oil Logistics segment for the periods indicated: Year Ended March 31, 2018 2017 Change (in thousands, except per barrel amounts)Revenues: Crude oil sales $2,151,203 $1,603,667 $547,536Crude oil transportation and other 122,786 70,027 52,759Total revenues (1) 2,273,989 1,673,694 600,295Expenses: Cost of sales-excluding impact of derivatives 2,120,640 1,573,246 547,394Cost of sales-derivative loss 7,021 5,579 1,442Operating expenses 47,846 41,535 6,311General and administrative expenses 6,584 5,961 623Depreciation and amortization expense 80,387 54,144 26,243(Gain) loss on disposal or impairment of assets, net (111,393) 10,704 (122,097)Total expenses 2,151,085 1,691,169 459,916Segment operating income (loss) $122,904 $(17,475) $140,379 Crude oil sold (barrels) 39,626 34,212 5,414Crude oil transported on owned pipelines (barrels) 33,454 6,365 27,089Crude oil storage capacity - owned and leased (barrels) (2) 6,159 7,024 (865)Crude oil storage capacity leased to third parties (barrels) (2) 2,641 3,717 (1,076)Crude oil inventory (barrels) (2) 1,219 2,844 (1,625)Crude oil sold ($/barrel) $54.288 $46.874 $7.414Cost per crude oil sold ($/barrel) $53.694 $46.148 $7.546Crude oil product margin ($/barrel) $0.594 $0.726 $(0.132) (1)Revenues include $13.9 million and $6.8 million of intersegment sales during the years ended March 31, 2018 and 2017, respectively, that are eliminated in our consolidatedstatements of operations.(2)Information is presented as of March 31, 2018 and March 31, 2017, respectively.Crude Oil Sales Revenues. The increase was due primarily to an increase in crude oil prices and sales volumes during the year ended March 31,2018, compared to the year ended March 31, 2017. This segment continued to be impacted by competition and low margins in the majority of the basinsacross the United States and we continue to market crude volumes in these basins to support our various pipeline, terminal and transportation assets.Additionally, we bear the cost of certain minimum volume commitments on third-party crude oil pipelines in various basins which are currently notprofitable.Crude Oil Transportation and Other Revenues. The increase was due primarily to our Grand Mesa Pipeline becoming operational on November 1,2016 which increased revenues by $55.0 million during the year ended March 31, 2018, compared to the year ended March 31, 2017. The increase was alsodue to increased volumes related to production growth in the DJ Basin. During the year ended March 31, 2018, approximately 33.5 million barrels of crudeoil were transported on the Grand Mesa Pipeline, which averaged approximately 92,000 barrels per day and financial volumes averaged approximately96,000 barrels per day (volume amounts are from both internal and external parties). Higher revenues in our trucking operations during the year endedMarch 31, 2018 were due primarily to increased demand for transportation services, compared to the year ended March 31, 2017, and were partially offset bythe flattening of the contango curve for crude oil (a condition in which forward crude oil prices are greater than spot prices) during the year ended March 31,2018, compared to the year ended March 31, 2017.63Table of ContentsCost of Sales-Excluding Impact of Derivatives. The increase was due primarily to an increase in crude oil prices during the year ended March 31,2018, compared to the year ended March 31, 2017.Cost of Sales-Derivatives. Our cost of sales during the year ended March 31, 2018 was increased by $4.2 million of net realized losses on derivativesand $2.8 million of net unrealized losses on derivatives. Our cost of sales during the year ended March 31, 2017 was increased by $7.1 million of net realizedlosses on derivatives and reduced by $1.5 million of net unrealized gains on derivatives.Operating and General and Administrative Expenses. The increase was due primarily to our Grand Mesa Pipeline becoming operational onNovember 1, 2016 which increased expenses by $8.0 million during the year ended March 31, 2018, compared to the year ended March 31, 2017. Thisincrease was partially offset by lower repair and maintenance expense associated with having a newer fleet of barges and a smaller fleet of trucks, as well asthe timing of repairs, and lower property taxes due to decreased inventory.Depreciation and Amortization Expense. The increase was due primarily to our Grand Mesa Pipeline becoming operational on November 1, 2016which increased depreciation and amortization expense by $23.0 million during the year ended March 31, 2018, compared to the year ended March 31,2017. Also contributing to the increase was higher depreciation expense related to other capital projects being placed into service.(Gain) Loss on Disposal or Impairment of Assets, Net. During the year ended March 31, 2018, we recorded a gain of $108.6 million on the sale of ourpreviously held 50% interest in Glass Mountain (see Note 2 to our consolidated financial statements included in this Annual Report). In addition, werecorded a net gain of $2.8 million on the sales of excess pipe and certain other assets. During the year ended March 31, 2017, we recorded a net loss of $6.5million on the sales of certain assets and a loss of $4.2 million due to the write-down of certain other assets.64Table of ContentsWater SolutionsThe following table summarizes the operating results of our Water Solutions segment for the periods indicated: Year Ended March 31, 2018 2017 Change (in thousands, except per barrel and per day amounts)Revenues: Service fees $149,114 $110,049 $39,065Recovered hydrocarbons 58,948 31,103 27,845Other revenues 21,077 18,449 2,628Total revenues 229,139 159,601 69,538Expenses: Cost of sales-excluding impact of derivatives 2,150 2,071 79Cost of sales-derivative loss 17,195 1,997 15,198Operating expenses 105,200 85,562 19,638General and administrative expenses 2,623 2,469 154Depreciation and amortization expense 98,623 101,758 (3,135)Loss (gain) on disposal or impairment of assets, net 6,863 (85,560) 92,423Revaluation of liabilities 20,716 6,717 13,999Total expenses 253,370 115,014 138,356Segment operating (loss) income $(24,231) $44,587 $(68,818) Wastewater processed (barrels per day) Eagle Ford Basin 235,713 208,649 27,064Permian Basin 289,360 184,702 104,658DJ Basin 113,771 68,253 45,518Other Basins 68,466 40,185 28,281Total 707,310 501,789 205,521Solids processed (barrels per day) 5,662 3,056 2,606Skim oil sold (barrels per day) 3,210 1,989 1,221Service fees for wastewater processed ($/barrel) $0.58 $0.60 $(0.02)Recovered hydrocarbons for wastewater processed ($/barrel) $0.23 $0.17 $0.06Operating expenses for wastewater processed ($/barrel) $0.41 $0.47 $(0.06)Service Fee Revenues. The increase was due primarily to an increase in the volume of wastewater processed, partially offset by higher volumes inareas with lower fees. We continue to benefit from the increased rig counts as compared to the prior year in the basins in which we operate, particularly in thePermian Basin.Recovered Hydrocarbon Revenues. The increase was due primarily to an increase in the volume of wastewater processed, an increase in the amountof hydrocarbons per barrel of wastewater processed and an increase in crude oil prices.Other Revenues. Other revenues primarily include solids disposal revenues and water pipeline revenues, both of which increased during the yearended March 31, 2018 due to increased volumes. These increases were partially offset by a decrease in freshwater revenues due to the sale of Grassland inNovember 2016 (see below discussion of the loss on the sale of Grassland).Cost of Sales-Excluding Impact of Derivatives. Cost of sales-excluding impact of derivatives, which primarily includes expenses to bring wastewaterto certain of our water solutions facilities, was consistent between the current year and prior year.Cost of Sales-Derivatives. We enter into derivatives in our Water Solutions segment to protect against the risk of a decline in the market price of thehydrocarbons we expect to recover when processing the wastewater and selling the skim oil. Our cost of sales during the year ended March 31, 2018 included$13.7 million of net unrealized losses on derivatives and $3.565Table of Contentsmillion of net realized losses on derivatives. Our cost of sales during the year ended March 31, 2017 included $4.1 million of net realized losses onderivatives and the reversal of $2.1 million of net unrealized losses on derivatives at March 31, 2016 as there were no open derivatives at March 31, 2017.Operating and General and Administrative Expenses. The increase was due primarily to higher costs of operations of water disposal wells due tohigher volumes processed, partially offset by cost reduction efforts. Due to the higher volumes processed, our cost per barrel has decreased, as shown in thetable above.Depreciation and Amortization Expense. The decrease was due primarily to lower amortization expense from the write-off of an intangible assetduring the year ended March 31, 2017 as well as certain intangible assets being fully amortized during the year ended March 31, 2017, partially offset byacquisitions and developed facilities (see Note 7 to our consolidated financial statements included in this Annual Report).Loss (Gain) on Disposal or Impairment of Assets, Net. During the year ended March 31, 2018, we recorded a loss of $8.2 million on the disposals ofcertain assets, partially offset by a gain of $1.3 million for the termination of a non-compete agreement, which included the carrying value of the non-compete agreement intangible asset that was written off (see Note 7 to our consolidated financial statements included in this Annual Report).During the year ended March 31, 2017, we recorded:•an adjustment of $124.7 million to the previously recorded $380.2 million estimated goodwill impairment charge recorded during the threemonths ended March 31, 2016 (see Note 6 to our consolidated financial statements included in this Annual Report);•a write-off of $5.2 million related to the value of an indefinite-lived trade name intangible asset in conjunction with finalizing our goodwillimpairment analysis (see Note 7 to our consolidated financial statements included in this Annual Report);•a loss of $22.7 million related to the termination of the development agreement, which included the carrying value of the developmentagreement asset that was written off (see Note 15 to our consolidated financial statements included in this Annual Report);•an impairment charge of $1.7 million to write down a loan receivable in June 2016 (see Note 13 to our consolidated financial statementsincluded in this Annual Report); and•a loss of $9.5 million on the sales of certain assets, including the sale of Grassland (see Note 13 to our consolidated financial statementsincluded in this Annual Report for a discussion of the sale of Grassland).Revaluation of Liabilities. The revaluation of liabilities represents the change in the valuation of our contingent consideration liabilities related toroyalty agreements acquired as part of certain business combinations during the year ended March 31, 2017. The increase in the expense during the yearended March 31, 2018 was due primarily to higher actual and expected production from new customers, resulting in an increase to the expected futureroyalty payment.66Table of ContentsLiquidsThe following table summarizes the operating results of our Liquids segment for the periods indicated: Year Ended March 31, 2018 2017 Change (in thousands, except per gallon amounts)Propane sales: Revenues (1) $1,203,486 $807,172 $396,314Cost of sales-excluding impact of derivatives 1,165,414 772,871 392,543Cost of sales-derivative gain (5,577) (2,633) (2,944)Product margin 43,649 36,934 6,715 Butane sales: Revenues (1) 562,066 391,265 170,801Cost of sales-excluding impact of derivatives 535,017 354,132 180,885Cost of sales-derivative loss 19,616 7,863 11,753Product margin 7,433 29,270 (21,837) Other product sales: Revenues (1) 432,570 308,031 124,539Cost of sales-excluding impact of derivatives 414,980 290,495 124,485Cost of sales-derivative gain (173) (1,477) 1,304Product margin 17,763 19,013 (1,250) Other revenues: Revenues (1) 22,548 32,648 (10,100)Cost of sales 3,930 12,893 (8,963)Product margin 18,618 19,755 (1,137) Expenses: Operating expenses 32,792 37,634 (4,842)General and administrative expenses 5,331 4,831 500Depreciation and amortization expense 24,937 19,163 5,774Loss on disposal or impairment of assets, net 117,516 92 117,424Total expenses 180,576 61,720 118,856Segment operating (loss) income $(93,113) $43,252 $(136,365) Liquids storage capacity - owned and leased (gallons) (2) 438,968 358,537 80,431 Propane sold (gallons) 1,361,173 1,267,076 94,097Propane sold ($/gallon) $0.884 $0.637 $0.247Cost per propane sold ($/gallon) $0.852 $0.608 $0.244Propane product margin ($/gallon) $0.032 $0.029 $0.003Propane inventory (gallons) (2) 48,928 48,351 577Propane storage capacity leased to third parties (gallons) (2) 29,662 33,495 (3,833) Butane sold (gallons) 544,750 456,586 88,164Butane sold ($/gallon) $1.032 $0.857 $0.175Cost per butane sold ($/gallon) $1.018 $0.793 $0.225Butane product margin ($/gallon) $0.014 $0.064 $(0.050)Butane inventory (gallons) (2) 15,385 9,438 5,947Butane storage capacity leased to third parties (gallons) (2) 51,660 80,346 (28,686) Other products sold (gallons) 400,405 343,365 57,040Other products sold ($/gallon) $1.080 $0.897 $0.183Cost per other products sold ($/gallon) $1.036 $0.842 $0.194Other products product margin ($/gallon) $0.044 $0.055 $(0.011)Other products inventory (gallons) (2) 5,822 6,426 (604)67Table of Contents (1)Revenues include $150.7 million and $100.0 million of intersegment sales during the years ended March 31, 2018 and 2017, respectively, that are eliminated in ourconsolidated statements of operations.(2)Information is presented as of March 31, 2018 and March 31, 2017, respectively.Propane Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales-excluding impact of derivatives weredue to higher commodity prices, and increased volume due to a new long-term marketing agreement.Cost of Sales-Derivatives. Our cost of wholesale propane sales was reduced by $1.0 million and $1.5 million of net unrealized gains on derivativesfor the years ended March 31, 2018 and 2017, respectively. Additionally, our cost of wholesale propane sales was reduced by $4.6 million and $1.1 millionof net realized gains on derivatives for the years ended March 31, 2018 and 2017, respectively.Product margins per gallon of propane sold were higher during the year ended March 31, 2018 than during the year ended March 31, 2017facilitated by stronger winter demand.Butane Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales-excluding impact of derivatives wereprimarily due to higher commodity prices.Cost of Sales-Derivatives. Our cost of butane sales was increased by $0.5 million and $2.0 million of net unrealized losses on derivatives for theyears ended March 31, 2018 and 2017, respectively. Additionally, our cost of butane sales was increased by $19.1 million and $5.9 million of net realizedlosses on derivatives for the years ended March 31, 2018 and 2017, respectively.Product margins per gallon of butane sold were lower during the year ended March 31, 2018 than during the year ended March 31, 2017 dueprimarily to the overall competitive nature of the market as well as higher than anticipated unrecovered railcar fleet costs.Other Products Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales-excluding impact ofderivatives were due primarily to a new long-term marketing agreement. Also, volumes have increased with the addition of the new Port Hudson terminal.Cost of Sales-Derivatives. Our cost of sales of other products was reduced by $0.1 million and $0.2 million of net unrealized gains on derivatives forthe years ended March 31, 2018 and 2017, respectively. Additionally, our cost of other products was reduced by $0.1 million and $1.3 million of net realizedgains on derivatives for the years ended March 31, 2018 and 2017, respectively.Product margin decrease during the year ended March 31, 2018 was due primarily to an increase in unrecovered railcar fleet costs.Other Revenues. This revenue includes storage, terminaling and transportation services income. The decrease was due primarily to reducedtransportation services and increased storage capacity available in the market.Operating and General and Administrative Expenses. The decrease was due primarily to a reduction in incentive compensation that was paid incommon units and reflected in “Corporate and Other”. Repair and maintenance expense was lower across most terminals due to tightly managing andprioritizing critical repairs.Depreciation and Amortization Expense. The increase was due primarily to the acquisition of two liquids facilities during the previous fiscal year.Loss on Disposal or Impairment of Assets, Net. During the year ended March 31, 2018, we recorded a goodwill impairment charge of $116.9 millionrelated to our salt dome storage facility in Utah due to the decreased demand for natural gas liquid storage and resulting decline in revenues and earnings ascompared to actual and projected results of prior and future periods (see Note 6 to our consolidated financial statements included in this Annual Report).During the years ended March 31, 2018 and 2017, we recorded a net loss of $0.6 million and $0.1 million, respectively, related to the retirement of assets.68Table of ContentsRetail PropaneThe following table summarizes the operating results of our Retail Propane segment for the periods indicated: Year Ended March 31, 2018 2017 Change (in thousands, except per gallon amounts)Propane sales: Revenues (1) $403,871 $308,919 $94,952Cost of sales 199,227 132,818 66,409Product margin 204,644 176,101 28,543 Distillate sales: Revenues (1) 75,183 64,249 10,934Cost of sales-excluding impact of derivatives 56,568 46,125 10,443Cost of sales-derivative loss 276 378 (102)Product margin 18,339 17,746 593 Other revenues: Revenues (1) 42,457 40,038 2,419Cost of sales 13,296 12,268 1,028Product margin 29,161 27,770 1,391 Expenses: Operating expenses 129,789 118,922 10,867General and administrative expenses 11,322 10,761 561Depreciation and amortization expense 43,692 42,966 726Gain on disposal or impairment of assets, net (88,209) (287) (87,922)Total expenses 96,594 172,362 (75,768)Segment operating income$155,550 $49,255 $106,295 Propane sold (gallons) 204,145 177,599 26,546Propane sold ($/gallon) $1.978 $1.739 $0.239Cost per propane sold ($/gallon) $0.976 $0.748 $0.228Propane product margin ($/gallon) $1.002 $0.991 $0.011Propane inventory (gallons) (2) 7,526 8,180 (654) Distillates sold (gallons) 30,491 30,001 490Distillates sold ($/gallon) $2.466 $2.142 $0.324Cost per distillates sold ($/gallon) $1.864 $1.550 $0.314Distillates product margin ($/gallon) $0.602 $0.592 $0.010Distillates inventory (gallons) (2) 1,051 1,148 (97) (1)Revenues include $0.1 million and $0.1 million of intersegment sales during the years ended March 31, 2018 and 2017, respectively, that are eliminated in our consolidatedstatement of operations.(2)Information is presented as of March 31, 2018 and March 31, 2017, respectively.Revenues and Cost of Sales. The increases in propane revenues and costs of sales were due primarily to increased volumes as a result of higherdemand related to colder winter weather and acquisitions made during the current and previous fiscal years, as well as an increase in commodity prices.Distillate revenues and cost of sales also increased due to the increase in commodity prices.Operating and General and Administrative Expenses. The increase was due primarily to increased expenses associated with acquisitions of retailpropane businesses.69Table of ContentsDepreciation and Amortization Expense.

The increases in revenues and cost of sales-excluding impact ofderivatives were due to an increase in refined products prices and increased volumes. The increased volumes were due primarily to additional pipelinecapacity rights purchased during the year ended March 31, 2017, an71Table of Contentsexpansion of our refined products operations and the continued demand for motor fuels. The decrease in margin was due primarily to negative impact of thecontinued decline in gasoline line space values on the Colonial Pipeline, discretionary terminal volume profitability and line space sales during the yearended March 31, 2018, compared to the year ended March 31, 2017. The average value of line space was approximately negative $0.007 per gallon for theyear ended March 31, 2018, compared to an average value of approximately $0.009 per gallon for the year ended March 31, 2017.Refined Products Cost of Sales-Derivatives. The margins for both the years ended March 31, 2018 and 2017 were negatively impacted by losses of$77.1 million and $43.4 million, respectively, from our risk management activities. These losses were due primarily to increasing future prices.Renewables Revenues and Cost of Sales-Excluding Impact of Derivatives. The decreases in revenues and cost of sales-excluding impact ofderivatives were due primarily to decreased volumes from the loss of a marketing contract with an equity method investee in December 2017, partially offsetby an increase in renewables prices. The margin was higher during the year ended March 31, 2018 due primarily to favorable biodiesel margins resulting fromthe biodiesel tax credit being reinstated in February 2018 for the 2017 calendar year.Renewables Cost of Sales-Derivatives. The margins for both the years ended March 31, 2018 and 2017 were negatively impacted by losses of $1.5million and $1.3 million, respectively, from our risk management activities. These losses were due primarily to the weakness in the price of renewableidentification numbers and increasing future prices.Service Fee Revenues, Operating Expenses, General and Administrative Expenses. The decreases were due primarily to the expiration of a transitionservices agreement in October 2016 related to the sale of the general partner interest in TLP in February 2016 whereby we were reimbursed for certainexpenses incurred on behalf of a third party.Depreciation and Amortization Expense. The decrease was due primarily to certain assets being fully depreciated during the year ended March 31,2017.Gain on Disposal or Impairment of Assets, Net. During the year ended March 31, 2018, we recorded $30.1 million of the deferred gain from the saleof the general partner interest in TLP in February 2016 (see Note 2 to our consolidated financial statements included in this Annual Report for a furtherdiscussion). In addition, we recorded a net loss of less than $0.1 million on the disposal of certain assets.During the year ended March 31, 2017, we recorded:•a $104.1 million gain from the sale of all of the TLP units we owned (see Note 2 to our consolidated financial statements included in thisAnnual Report for a further discussion);•$30.1 million of the deferred gain from the sale of the general partner in interest in TLP in February 2016 (see Note 2 to our consolidatedfinancial statements included in this Annual Report for a further discussion); and•a loss of $0.1 million on the sales of certain assets.72Table of ContentsCorporate and OtherThe operating loss within “Corporate and Other” includes the following components for the periods indicated: Year Ended March 31, 2018 2017 Change (in thousands)Other revenues: Revenues $1,174 $844 $330Cost of sales 530 400 130Margin 644 444 200 Expenses: Operating expenses 1,292 1,192 100General and administrative expenses 75,158 82,723 (7,565)Depreciation and amortization expense 3,779 3,612 167Loss (gain) on disposal or impairment of assets, net 8 (1) 9Total expenses 80,237 87,526 (7,289)Operating loss $(79,593) $(87,082) $7,489General and Administrative Expenses. The decrease for the year ended March 31, 2018 was due primarily to a decrease in equity-basedcompensation expense related to service awards. The expense related to service awards was $16.2 million for the year ended March 31, 2018, compared to$37.2 million for the year ended March 31, 2017. The increase in expense in the prior fiscal year was due to the cancellation of awards which accelerated theexpense reporting. In addition, during the first quarter of the prior fiscal year, the expense for the service awards was accounted for under the liability methodand due to an increase in our unit price during that period, we recorded an increase in equity-based compensation expense. Also, see Note 10 to ourconsolidated financial statements included in this Annual Report for a further discussion of our equity-based compensation. The decrease from equity-basedcompensation was partially offset by increases in legal expenses and workmen’s compensation.Equity in Earnings of Unconsolidated EntitiesThe increase of $4.9 million during the year ended March 31, 2018 was due primarily to increased earnings related to our investment in GlassMountain. On December 22, 2017, we sold our previously held 50% interest in Glass Mountain. See Note 2 to our consolidated financial statements includedin this Annual Report for a further discussion.Interest ExpenseInterest expense includes interest charged on our revolving credit facilities, senior secured notes, and senior unsecured notes, as well as amortizationof debt issuance costs, letter of credit fees, interest on equipment financing notes, and accretion of interest on non-interest bearing debt obligations. Theincrease of $49.1 million during the year ended March 31, 2018 was due primarily to the issuance of the 2023 Notes and 2025 Notes which have higherinterest rates than our revolving credit facility. This was offset by lower interest expense on our revolving credit facility as our average balance outstandingdecreased from $1.7 billion for the year ended March 31, 2017 to $1.0 billion for the year ended March 31, 2018.73Table of Contents(Loss) Gain on Early Extinguishment of Liabilities, NetThe following table summarizes the components of (loss) gain on early extinguishment of liabilities, net for the periods indicated: Year Ended March 31, 2018 2017 (in thousands)Early extinguishment of long-term debt (1)$(23,201) $6,922Release of contingent consideration liabilities (2)— 22,278Write-off deferred debt issuance costs (3)— (4,473)(Loss) gain on early extinguishment of liabilities, net$(23,201) $24,727 (1)During the year ended March 31, 2018, this relates to net losses (inclusive of debt issuance costs written off) on the early extinguishment of all of the senior secured notes anda portion of the 2019 Notes, 2023 Notes and 2025 Notes.

The decrease in income tax expense was due primarily to a lower state franchise tax liability in Texas as well as a lower Canadian taxliability from our taxable corporate subsidiaries in Canada. See Note 2 to our consolidated financial statements included in this Annual Report for a furtherdiscussion.Noncontrolling Interests - Redeemable and Non-redeemableNoncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. The decrease of $5.6 millionduring the year ended March 31, 2018 was due primarily to adjustments related to noncontrolling interests during the year ended March 31, 2017.Segment Operating Results for the Years Ended March 31, 2017 and 2016Crude Oil LogisticsThe following table summarizes the operating results of our Crude Oil Logistics segment for the periods indicated: Year Ended March 31, 2017 2016 Change (in thousands, except per barrel amounts)Revenues: Crude oil sales $1,603,667 $3,170,891 $(1,567,224)Crude oil transportation and other 70,027 55,882 14,145Total revenues (1) 1,673,694 3,226,773 (1,553,079)Expenses: Cost of sales-excluding impact of derivatives 1,573,246 3,133,097 (1,559,851)Cost of sales-derivative loss (gain) 5,579 (11,686) 17,265Operating expenses 41,535 43,458 (1,923)General and administrative expenses 5,961 8,334 (2,373)Depreciation and amortization expense 54,144 39,363 14,781Loss on disposal or impairment of assets, net 10,704 54,952 (44,248)Total expenses 1,691,169 3,267,518 (1,576,349)Segment operating loss $(17,475) $(40,745) $23,270 Crude oil sold (barrels) 34,212 67,211 (32,999)Crude oil transported on owned pipelines (barrels) 6,365 — 6,365Crude oil storage capacity - owned and leased (barrels) (2) 7,024 6,115 909Crude oil storage capacity leased to third parties (barrels) (2) 3,717 3,127 590Crude oil inventory (barrels) (2) 2,844 2,123 721Crude oil sold ($/barrel) $46.874 $47.178 $(0.304)Cost per crude oil sold ($/barrel) $46.148 $46.442 $(0.294)Crude oil product margin ($/barrel) $0.726 $0.736 $(0.010) (1)Revenues include $6.8 million and $9.7 million of intersegment sales during the years ended March 31, 2017 and 2016, respectively, that are eliminated in our consolidatedstatements of operations.(2)Information is presented as of March 31, 2017 and March 31, 2016, respectively.Crude Oil Sales Revenues. The decrease in our sales volume was due primarily to increased competition. In addition, we also had an increase inbuy/sell transactions during the year ended March 31, 2017, compared to the year ended March 31, 2016. These are transactions in which we transact topurchase product from a counterparty and sell the same volumes of product to the same counterparty at a different location or time. As the revenues and costsof sales are netted for these transaction, so are the volumes.75Table of ContentsCrude Oil Transportation and Other Revenues. The increase was due primarily to our Grand Mesa Pipeline becoming operational on November 1,2016 with revenues of $29.2 million, partially offset by the flattening of the contango curve for crude oil (a condition in which forward crude oil prices aregreater than spot prices) during the year ended March 31, 2017, compared to the year ended March 31, 2016, and lower revenues in our trucking and bargeoperations during the year ended March 31, 2017 due to a general slowdown in demand for transportation services, compared to the year ended March 31,2016.Cost of Sales-Excluding Impact of Derivatives. The decrease was due primarily to the decline in crude oil prices and volumes due to increasedcompetition during the year ended March 31, 2017, compared to the year ended March 31, 2016.Cost of Sales-Derivatives. Our cost of sales during the year ended March 31, 2017 was increased by $7.1 million of net realized losses on derivativesand reduced by $1.5 million of net unrealized gains on derivatives. Our cost of sales during the year ended March 31, 2016 was reduced by $13.8 million ofnet realized gains on derivatives and increased by $2.1 million of net unrealized losses on derivatives.Operating and General and Administrative Expenses. The decrease was due primarily to lower compensation expense related to a reduction in thenumber of employees as a result of organizational changes, lower repair and maintenance expense related to trucking operations resulting from a generalslowdown in demand for transportation services, and lower repair and maintenance expense related to having a newer fleet of barges and the timing of repairs,partially offset by our Grand Mesa Pipeline becoming operational on November 1, 2016 which incurred operating expenses of $4.8 million.Depreciation and Amortization Expense. The increase was due primarily to our Grand Mesa Pipeline becoming operational on November 1, 2016,partially offset by certain intangible assets being fully amortized during the year ended March 31, 2016.Loss on Disposal or Impairment of Assets, Net. During the year ended March 31, 2017, we recorded a net loss of $6.5 million on the sales of certainassets and a loss of $4.2 million due to the write-down of certain other assets. During the year ended March 31, 2016, we recorded a loss of $50.1 million dueto the write-down of certain assets, a loss of $3.1 million due to the cancellation of two previously-planned projects and a loss of $1.8 million on the sales ofcertain other assets.76Table of ContentsWater SolutionsThe following table summarizes the operating results of our Water Solutions segment for the periods indicated: Year Ended March 31, 2017 2016 Change (in thousands, except per barrel and per day amounts)Revenues: Service fees $110,049 $136,710 $(26,661)Recovered hydrocarbons 31,103 41,090 (9,987)Other revenues 18,449 7,201 11,248Total revenues 159,601 185,001 (25,400)Expenses: Cost of sales-excluding impact of derivatives 2,071 (241) 2,312Cost of sales-derivative loss (gain) 1,997 (7,095) 9,092Operating expenses 85,562 112,538 (26,976)General and administrative expenses 2,469 2,778 (309)Depreciation and amortization expense 101,758 91,685 10,073(Gain) loss on disposal or impairment of assets, net (85,560) 381,682 (467,242)Revaluation of liabilities 6,717 (82,673) 89,390Total expenses 115,014 498,674 (383,660)Segment operating income (loss) $44,587 $(313,673) $358,260 Wastewater processed (barrels per day) Eagle Ford Basin 208,649 236,792 (28,143)Permian Basin 184,702 179,413 5,289DJ Basin 68,253 107,353 (39,100)Other Basins 40,185 45,949 (5,764)Total 501,789 569,507 (67,718)Solids processed (barrels per day) 3,056 3,149 (93)Skim oil sold (barrels per day) 1,989 2,935 (946)Service fees for wastewater processed ($/barrel) $0.60 $0.66 $(0.06)Recovered hydrocarbons for wastewater processed ($/barrel) $0.17 $0.20 $(0.03)Operating expenses for wastewater processed ($/barrel) $0.47 $0.54 $(0.07)Service Fee Revenues. The decrease was due primarily to a decrease in the volume processed from a slowdown in customer production anddevelopment activity and a lower price per barrel received in current market conditions from new facilities being operational during the year endedMarch 31, 2017.Recovered Hydrocarbon Revenues. The decrease was due primarily to a decrease in the volume of wastewater processed and a decrease in theamount of hydrocarbons per barrel of wastewater processed.Other Revenues. The increase was due primarily to an increase in revenues in the freshwater and water pipeline businesses as well as revenue fromtrucking wastewater to certain of our water solutions facilities. See the below discussion of the loss on the sale of Grassland.Cost of Sales-Excluding Impact of Derivatives. The increase was due to trucking expenses to bring wastewater to certain of our water solutionsfacilities.Cost of Sales-Derivatives. We enter into derivatives in our Water Solutions segment to protect against the risk of a decline in the market price of thehydrocarbons we expect to recover when processing the wastewater and selling the skim oil. Our cost of sales during the year ended March 31, 2017 included$4.1 million of net realized losses on derivatives and the reversal of $2.1 million of net unrealized losses on derivatives at March 31, 2016 as there were noopen derivatives at March 31, 2017. Our cost of sales during the year ended March 31, 2016 included $10.3 million of net realized gains on77Table of Contentsderivatives and $3.2 million of net unrealized losses on derivatives. In December 2015, we settled derivative contracts that had scheduled settlement datesfrom January 2016 through December 2016, in order to lock in the gains on those derivatives.Operating and General and Administrative Expenses. The decrease was due primarily to lower costs of operations of water disposal wells due tolower volumes processed and cost reduction efforts.Depreciation and Amortization Expense. The increase was due primarily to acquisitions and developed facilities, partially offset by loweramortization expense from the write-off of an intangible asset as well as certain intangible assets being fully amortized during the years ended March 31,2017 and 2016 (see Note 7 to our consolidated financial statements included in this Annual Report).(Gain) Loss on Disposal or Impairment of Assets, Net. During the year ended March 31, 2017, we recorded:•an adjustment of $124.7 million to the previously recorded $380.2 million estimated goodwill impairment charge recorded during the threemonths ended March 31, 2016 (see Note 6 to our consolidated financial statements included in this Annual Report);•a write-off of $5.2 million related to the value of an indefinite-lived trade name intangible asset in conjunction with finalizing our goodwillimpairment analysis (see Note 7 to our consolidated financial statements included in this Annual Report);•a loss of $22.7 million related to the termination of the development agreement, which included the carrying value of the developmentagreement asset that was written off (see Note 15 to our consolidated financial statements included in this Annual Report);•an impairment charge of $1.7 million to write down a loan receivable in June 2016 (see Note 13 to our consolidated financial statementsincluded in this Annual Report); and•a loss of $9.5 million on the sales of certain assets, including the sale of Grassland (see Note 13 to our consolidated financial statementsincluded in this Annual Report for a discussion of the sale of Grassland).During the year ended March 31, 2016, we recorded:•an estimated goodwill impairment charge of $380.2 million as the decline in crude oil prices and crude oil production have had an unfavorableimpact on our Water Solutions business (see Note 6 to our consolidated financial statements included in this Annual Report); and•a loss of $1.5 million on the sales of certain other assets.Revaluation of Liabilities. The revaluation of liabilities represents the change in the valuation of our contingent consideration liabilities related toroyalty agreements acquired as part of certain business combinations during the years ended March 31, 2017 and 2016. The increase in the expense duringthe year ended March 31, 2017 was due primarily to the reduction in the liability recorded during the year ended March 31, 2016 due to lower anticipatedproduction and development activity due to lower commodity prices.78Table of ContentsLiquidsThe following table summarizes the operating results of our Liquids segment for the periods indicated: Year Ended March 31, 2017 2016 Change (in thousands, except per gallon amounts)Propane sales: Revenues (1) $807,172 $618,919 $188,253Cost of sales-excluding impact of derivatives 772,871 570,495 202,376Cost of sales - derivative (gain) loss (2,633) 1,239 (3,872)Product margin 36,934 47,185 (10,251) Butane sales: Revenues (1) 391,265 317,994 73,271Cost of sales-excluding impact of derivatives 354,132 269,310 84,822Cost of sales-derivative loss (gain) 7,863 (4,092) 11,955Product margin 29,270 52,776 (23,506) Other product sales: Revenues (1) 308,031 302,181 5,850Cost of sales-excluding impact of derivatives 290,495 266,492 24,003Cost of sales-derivative (gain) loss (1,477) 426 (1,903)Product margin 19,013 35,263 (16,250) Other revenues: Revenues (1) 32,648 35,943 (3,295)Cost of sales 12,893 13,806 (913)Product margin 19,755 22,137 (2,382) Expenses: Operating expenses 37,634 45,140 (7,506)General and administrative expenses 4,831 8,806 (3,975)Depreciation and amortization expense 19,163 15,642 3,521Loss on disposal or impairment of assets, net 92 11,600 (11,508)Total expenses 61,720 81,188 (19,468)Segment operating income $43,252 $76,173 $(32,921) Liquids storage capacity - owned and leased (gallons) (2) 358,537 292,110 66,427 Propane sold (gallons) 1,267,076 1,244,529 22,547Propane sold ($/gallon) $0.637 $0.497 $0.140Cost per propane sold ($/gallon) $0.608 $0.459 $0.149Propane product margin ($/gallon) $0.029 $0.038 $(0.009)Propane inventory (gallons) (2) 48,351 56,584 (8,233)Propane storage capacity leased to third parties (gallons) (2) 33,495 33,264 231 Butane sold (gallons) 456,586 483,206 (26,620)Butane sold ($/gallon) $0.857 $0.658 $0.199Cost per butane sold ($/gallon) $0.793 $0.549 $0.244Butane product margin ($/gallon) $0.064 $0.109 $(0.045)Butane inventory (gallons) (2) 9,438 14,629 (5,191)Butane storage capacity leased to third parties (gallons) (2) 80,346 72,450 7,896 Other products sold (gallons) 343,365 360,716 (17,351)Other products sold ($/gallon) $0.897 $0.838 $0.059Cost per other products sold ($/gallon) $0.842 $0.740 $0.102Other products product margin ($/gallon) $0.055 $0.098 $(0.043)Other products inventory (gallons) (2) 6,426 6,297 12979Table of Contents (1)Revenues include $100.0 million and $80.6 million of intersegment sales during the years ended March 31, 2017 and 2016, respectively, that are eliminated in our consolidatedstatements of operations.(2)Information is presented as of March 31, 2017 and March 31, 2016, respectively.Propane Sales. The increase in revenues was due to higher commodity prices, partially offset by warmer winter temperatures, as compared to theprior year, experienced by certain regions in which we operate.Our cost of wholesale propane sales was reduced by $1.5 million and $2.1 million, respectively, of net unrealized gains on derivatives for the yearsended March 31, 2017 and 2016. Additionally, our cost of wholesale propane sales was reduced by $1.1 million of net realized gains on derivatives andincreased by $3.4 million of net realized losses on derivatives for the years ended March 31, 2017 and 2016, respectively.Product margins per gallon of propane sold were lower during the year ended March 31, 2017 than during the year ended March 31, 2016. Propaneprices declined significantly during February and March of 2017. Declining propane prices typically have an adverse effect on our margins as we were unableto fully recoup fixed storage fees and railcar lease costs.Butane Sales. The increase in revenues and cost of sales was primarily a function of higher commodity prices.Our cost of butane sales during the year ended March 31, 2017 was increased by $2.0 million of net unrealized losses on derivatives, as compared toa reduction of $1.9 million of net unrealized gains on derivatives during the year ended March 31, 2016. Additionally, our cost of butane sales was increasedby $5.9 million of net realized losses on derivatives and reduced by $2.2 million of net realized gains on derivatives for the years ended March 31, 2017 and2016, respectively.Product margins per gallon of butane sold were lower during the year ended March 31, 2017 than during the year ended March 31, 2016 primarilydue to underutilization of our leased railcar fleet.Other Products Sales. The decrease in revenues was primarily due to lower volumes as a result of decreases in production related to a customer’scontract.Our cost of sales of other products during the year ended March 31, 2017 was reduced by $0.2 million of net unrealized gains on derivatives, ascompared to less than $0.1 million of net unrealized losses on derivatives during the year ended March 31, 2016. Additionally, our cost of other products wasreduced by $1.3 million of net realized gains on derivatives and increased by $0.4 million of net realized losses on derivatives for the years ended March 31,2017 and 2016, respectively.Product margins during the year ended March 31, 2017 decreased primarily due to a decline in the margin on sales of asphalt, as commodity priceswhich correlate with crude oil prices have declined.Other Revenues. This revenue includes storage, terminaling and transportation services income. Other revenues decreased due to the increasedavailability of transportation services and storage capacity in the market. While railcars costs have held steady, the value we are able to realize for the railcarin the market has dropped significantly year over year, resulting in lower revenues and volumes, however costs have remained consistent.Operating and General and Administrative Expenses. The decrease was due primarily to a reduction in overall compensation expenses due to lowerincentive compensation and commission expense as well as continued cost management monitoring which focuses on expense reductions.Depreciation and Amortization Expense. The increase was due to expansion of existing terminals and acquisition of two new terminals.Loss on Disposal or Impairment of Assets, Net. During the year ended March 31, 2016, we wrote off assets of $14.6 million acquired as part of theGavilon Energy acquisition that we deemed no longer recoverable. During the year ended March 31, 2016, we received a payment of $3.0 million from thestate of Maine to relocate certain terminal assets.80Table of ContentsRetail PropaneThe following table summarizes the operating results of our Retail Propane segment for the periods indicated: Year Ended March 31, 2017 2016 Change (in thousands, except per gallon amounts)Propane sales: Revenues (1) $308,919 $248,673 $60,246Cost of sales 132,818 95,191 37,627Product margin 176,101 153,482 22,619 Distillate sales: Revenues (1) 64,249 64,868 (619)Cost of sales-excluding impact of derivatives 46,125 48,972 (2,847)Cost of sales-derivative loss (gain) 378 (781) 1,159Product margin 17,746 16,677 1,069 Other product sales: Revenues (1) 40,038 39,436 602Cost of sales 12,268 13,375 (1,107)Product margin 27,770 26,061 1,709 Expenses: Operating expenses 118,922 104,287 14,635General and administrative expenses 10,761 11,982 (1,221)Depreciation and amortization expense 42,966 35,992 6,974Gain on disposal or impairment of assets, net (287) (137) (150)Total expenses 172,362 152,124 20,238Segment operating income $49,255 $44,096 $5,159 Propane sold (gallons) 177,599 152,238 25,361Propane sold ($/gallon) $1.739 $1.633 $0.106Cost per propane sold ($/gallon) $0.748 $0.625 $0.123Propane product margin ($/gallon) $0.991 $1.008 $(0.017)Propane inventory (gallons) (2) 8,180 7,314 866 Distillates sold (gallons) 30,001 30,674 (673)Distillates sold ($/gallon) $2.142 $2.115 $0.027Cost per distillates sold ($/gallon) $1.550 $1.571 $(0.021)Distillates product margin ($/gallon) $0.592 $0.544 $0.048Distillates inventory (gallons) (2) 1,148 1,223 (75) (1)Revenues include $0.1 million of intersegment sales during the year ended March 31, 2017 that are eliminated in our consolidated statement of operations.(2)Information is presented as of March 31, 2017 and March 31, 2016, respectively.Revenues. The increase in propane revenues was primarily due to the four acquisitions in fiscal year 2017, partially offset by warmer wintertemperatures, as compared to the prior year, experienced by certain regions in which we operate.81Table of ContentsCost of Sales. The increase in propane cost of sales was due to the acquisitions in fiscal year 2017 as well as an increase in commodity prices. Thedecrease in distillates cost of sales was due to lower commodity prices in the first and second quarter of fiscal year 2017.Operating and General and Administrative Expenses. The increase was due primarily to increased expenses associated with acquisitions of retailpropane businesses.Depreciation and Amortization Expense. The increase was due primarily to acquisitions of retail propane businesses.82Table of ContentsRefined Products and RenewablesThe following table summarizes the operating results of our Refined Products and Renewables segment for the periods indicated. As previouslyreported, on February 1, 2016, we sold our general partner interest in TLP. As a result, on February 1, 2016, we deconsolidated TLP and began to account forour limited partner investment in TLP using the equity method of accounting. Also, on April 1, 2016, we sold all of the TLP common units we owned.

The increases in revenues and cost of sales-excluding impact ofderivatives were due primarily to increased volumes from additional pipeline capacity rights purchased during the years ended March 31, 2017 and 2016, anexpansion of our refined products operations, and the continued demand for motor fuels in the current low gasoline price environment. These increases werepartially offset by a decrease in refined products sale prices during the year ended March 31, 2017 as well as storage fees paid to TLP no longer beingeliminated as TLP was deconsolidated on February 1, 2016.Refined Products Cost of Sales-Derivatives. The margin for the year ended March 31, 2017 was negatively impacted by a loss of $43.4 million fromour risk management activities due primarily to increasing future prices. The margin for the year ended March 31, 2016 was positively impacted by a gain of$78.8 million from our risk management activities due primarily to decreasing future prices.Renewables Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales-excluding impact of derivativeswere due primarily to increased volumes from being able to liquidate storage volumes as the renewables markets shifted from being in contango (a conditionin which forward renewables prices are greater than spot prices) to being backwardated (a condition in which forward renewables prices are lower than spotprices) during the year ended March 31, 2017. These increases were partially offset by a decrease in renewables sale prices and a decrease in the cost ofrenewables purchased during the year ended March 31, 2017. Margins for biodiesel are impacted by a biodiesel tax credit. When the tax credit is passed atthe end of the calendar year and retroactive for the entire calendar year, it allows for more optionality and trading in the market and allows us to enter intodeals that could provide for a positive upside if that credit is passed. Product margins were lower during the year ended March 31, 2017, compared to the yearended March 31, 2016 as a result of the biodiesel tax credit being in place for the entire 2016 calendar year, compared to being reinstated in December 2015for the 2015 calendar year.Renewables Cost of Sales-Derivatives. The margin for the year ended March 31, 2017 was negatively impacted by a loss of $1.3 million from ourrisk management activities due primarily to the weakness in the price of renewable identification numbers and increasing future prices. The margin for theyear ended March 31, 2016 was positively impacted by a gain of $2.5 million from our risk management activities due primarily to decreasing future prices.Service Fee Revenues, Operating Expenses, General and Administrative Expenses, Depreciation and Amortization Expense. The decreases were dueprimarily to the inclusion of TLP for ten months of the year ended March 31, 2016 with no comparable activity during the year ended March 31, 2017, asTLP was deconsolidated on February 1, 2016.Gain on Disposal or Impairment of Assets, Net. During the year ended March 31, 2017, we recorded:•a $104.1 million gain from the sale of all of the TLP units we owned (see Note 2 to our consolidated financial statements included in thisAnnual Report for a further discussion);•$30.1 million of the deferred gain from the sale of the general partner in interest in TLP in February 2016 (see Note 2 to our consolidatedfinancial statements included in this Annual Report for a further discussion); and•a loss of $0.1 million on the sales of certain assets.During the year ended March 31, 2016, we recorded:•a gain on disposal of our general partner interest in TLP of $329.9 million, of which $204.6 million was deferred and $5.0 million of thedeferred gain was recorded during the year ended March 31, 2016 (see Note 2 to our consolidated financial statements included in this AnnualReport for a further discussion);•a loss of $1.8 million related to certain property, plant and equipment that we have retired; and•a loss of $1.3 million related to the sale of certain tank bottoms.84Table of ContentsCorporate and OtherThe operating loss within “Corporate and Other” includes the following components for the periods indicated: Year Ended March 31, 2017 2016 Change (in thousands)Other revenues: Revenues $844 $462 $382Cost of sales 400 182 218Margin 444 280 164 Expenses: Operating expenses 1,192 338 854General and administrative expenses 82,723 91,966 (9,243)Depreciation and amortization expense 3,612 5,381 (1,769)Gain on disposal or impairment of assets, net (1) — (1)Total expenses 87,526 97,685 (10,159)Operating loss $(87,082) $(97,405) $10,323General and Administrative Expenses. The decrease was due primarily to lower equity-based compensation expense. We recorded expense of $7.2million for the year ended March 31, 2017, compared to $16.4 million for the year ended March 31, 2016. The year ended March 31, 2016 included theinitial grant of the performance units as well as the vesting of the first tranche. The expense associated with the service award units (exclusive of accruals ofannual bonuses paid or expected to be paid in common units) was $37.2 million during the year ended March 31, 2017, compared to $35.2 million duringthe year ended March 31, 2016. The increase was due primarily to a change in our process for the withholding of taxes on vesting which no longer requires usto revalue our unvested units each period. During the year ended March 31, 2016, the value of the unvested units was reduced due to declines in our unitprice and resulted in the reversal of previously recorded compensation expense. See Note 10 to our consolidated financial statements included in this AnnualReport for a further discussion.Equity in Earnings of Unconsolidated EntitiesThe decrease of $13.0 million during the year ended March 31, 2017 was due primarily to a decrease of $12.6 million as a result of deconsolidatingTLP on February 1, 2016 and selling all of the TLP common units we owned on April 1, 2016 (see Note 2 to our consolidated financial statements includedin this Annual Report).Revaluation of InvestmentsOn June 3, 2016, we acquired the remaining 65% ownership interest in Grassland. Prior to the completion of this transaction, we accounted for ourpreviously held 35% ownership interest in Grassland using the equity method of accounting. As we owned a controlling interest in Grassland, we revaluedour previously held 35% ownership interest to fair value of $0.8 million and recorded a loss of $14.9 million. As the amount paid (cash plus the fair value ofour previously held ownership interest) was less than the fair value of the assets acquired and liabilities assumed, we recorded a bargain purchase gain of $0.6million (see Note 13 to our consolidated financial statements included in this Annual Report).Interest ExpenseThe increase of $17.4 million during the year ended March 31, 2017 was due primarily to the issuance of the 2023 Notes and 2025 Notes whichhave higher interest rates than our revolving credit facility, partially offset by lower interest expense related to TLP’s credit facility (our interest in TLP wasacquired in July 2014, and we deconsolidated TLP as of February 1, 2016) and lower interest expense as we repurchased a portion of the 2019 Notes and2021 Notes during the years ended March 31, 2017 and 2016.85Table of ContentsGain on Early Extinguishment of Liabilities, NetThe following table summarizes the components of gain on early extinguishment of liabilities, net for the periods indicated: Year Ended March 31, 2017 2016 (in thousands)Release of contingent consideration liabilities (1)$22,278 $—Early extinguishment of long-term debt (2)6,922 28,532Write-off deferred debt issuance costs (3)(4,473) —Gain on early extinguishment of liabilities, net$24,727 $28,532 (1)Relates to the release of certain contingent consideration liabilities in conjunction with the termination of the development agreement in June 2016 (see Note 15 to ourconsolidated financial statements included in this Annual Report for a further discussion).

On June 3, 2016, weacquired the remaining 65% ownership interest in Grassland and all interest income on the receivable from Grassland has been eliminated in consolidation subsequent to thatdate.(2)Represents another party’s share of the profits and losses generated from a joint crude oil marketing arrangement.(3)Represents a gain from the termination of a storage sublease agreement (see Note 15 to our consolidated financial statements included in this Annual Report for a furtherdiscussion).(4)During the year ended March 31, 2017, this relates primarily to a distribution from TLP pursuant to the agreement to sell all of the TLP common units we owned in April2016, a gain on insurance settlement related to business interruption insurance coverage on a facility in our Water Solutions segment and a payment received related to acontract termination.Income Tax Expense (Benefit)Income tax expense was $1.9 million during the year ended March 31, 2017, compared to an income tax benefit of $0.4 million during the yearended March 31, 2016. Income tax benefit during the year ended March 31, 2016 included a benefit of $3.6 million related to a change in estimate of theincome tax obligation payable related to TransMontaigne Inc. See Note 2 to our consolidated financial statements included in this Annual Report for afurther discussion.86Table of ContentsNoncontrolling Interests - Redeemable and Non-redeemableThe decrease of $5.0 million during the year ended March 31, 2017 was due primarily to the deconsolidation of TLP on February 1, 2016 as a resultof the sale of our general partner interest in TLP, partially offset by adjustments related to noncontrolling interests.Non-GAAP Financial MeasuresIn addition to financial results reported in accordance with accounting principles generally accepted in the United States (“GAAP”), we haveprovided the non-GAAP financial measures of EBITDA and Adjusted EBITDA. These non-GAAP financial measures are not intended to be a substitute forthose reported in accordance with GAAP. These measures may be different from non-GAAP financial measures used by other entities, even when similar termsare used to identify such measures.We define EBITDA as net income (loss) attributable to NGL Energy Partners LP, plus interest expense, income tax expense (benefit), anddepreciation and amortization expense. We define Adjusted EBITDA as EBITDA excluding net unrealized gains and losses on derivatives, lower of cost ormarket adjustments, gains and losses on disposal or impairment of assets, gains and losses on early extinguishment of liabilities, revaluation of investments,equity-based compensation expense, acquisition expense, revaluation of liabilities and other. We also include in Adjusted EBITDA certain inventoryvaluation adjustments related to our Refined Products and Renewables segment, as discussed below. EBITDA and Adjusted EBITDA should not beconsidered alternatives to net (loss) income, (loss) income before income taxes, cash flows from operating activities, or any other measure of financialperformance calculated in accordance with GAAP, as those items are used to measure operating performance, liquidity or the ability to service debtobligations. We believe that EBITDA provides additional information to investors for evaluating our ability to make quarterly distributions to ourunitholders and is presented solely as a supplemental measure. We believe that Adjusted EBITDA provides additional information to investors for evaluatingour financial performance without regard to our financing methods, capital structure and historical cost basis. Further, EBITDA and Adjusted EBITDA, as wedefine them, may not be comparable to EBITDA, Adjusted EBITDA, or similarly titled measures used by other entities.Other than for our Refined Products and Renewables segment, for purposes of our Adjusted EBITDA calculation, we make a distinction betweenrealized and unrealized gains and losses on derivatives. During the period when a derivative contract is open, we record changes in the fair value of thederivative as an unrealized gain or loss. When a derivative contract matures or is settled, we reverse the previously recorded unrealized gain or loss and recorda realized gain or loss. We do not draw such a distinction between realized and unrealized gains and losses on derivatives of our Refined Products andRenewables segment. The primary hedging strategy of our Refined Products and Renewables segment is to hedge against the risk of declines in the value ofinventory over the course of the contract cycle, and many of the hedges are six months to one year in duration at inception. The “inventory valuationadjustment” row in the reconciliation table reflects the difference between the market value of the inventory of our Refined Products and Renewablessegment at the balance sheet date and its cost. We include this in Adjusted EBITDA because the unrealized gains and losses associated with derivativecontracts associated with the inventory of this segment, which are intended primarily to hedge inventory holding risk and are included in net income, alsoaffect Adjusted EBITDA.87Table of ContentsThe following table reconciles net (loss) income to EBITDA and Adjusted EBITDA: Year Ended March 31, 2018 2017 2016 (in thousands)Net (loss) income $(69,605) $143,874 $(187,097)Less: Net income attributable to noncontrolling interests (240) (6,832) (11,832)Less: Net income attributable to redeemable noncontrolling interests (1,030) — —Net (loss) income attributable to NGL Energy Partners LP (70,875) 137,042 (198,929)Interest expense 199,747 150,504 126,514Income tax expense (benefit) 1,458 1,939 (420)Depreciation and amortization 266,525 238,583 217,893EBITDA 396,855 528,068 145,058Net unrealized losses (gains) on derivatives 15,883 (3,338) 1,255Inventory valuation adjustment (1) 11,033 7,368 24,390Lower of cost or market adjustments 399 (1,283) (5,932)(Gain) loss on disposal or impairment of assets, net (105,313) (209,213) 320,783Loss (gain) on early extinguishment of liabilities, net 23,201 (24,727) (28,532)Revaluation of investments — 14,365 —Equity-based compensation expense (2) 35,241 53,102 58,816Acquisition expense (3) 263 1,771 2,002Revaluation of liabilities (4) 20,607 12,761 (90,700)Other (5) 10,081 2,443 (2,645)Adjusted EBITDA $408,250 $381,317 $424,495 (1)Amount reflects the difference between the market value of the inventory of our Refined Products and Renewables segment at the balance sheet date and its cost.

See Note 8 to our consolidated financial statements included in this Annual Report for a detailed description of ourlong-term debt. Our cash flows from operations are discussed below.Our borrowing needs vary during the year due in part to the seasonal nature of our Liquids, Retail Propane and Refined Products and Renewablesbusinesses. Our greatest working capital borrowing needs generally occur during the period of June through December, when we are building our natural gasliquids inventories in anticipation of the heating season as well as building our gasoline inventory in anticipation of the winter gasoline contango andblending season. Our working capital borrowing needs generally decline during the period of January through March, when the cash flows from our RetailPropane and Liquids segments are the greatest and gasoline inventories need to be minimized due to certain inventory requirements.Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash (as defined in ourpartnership agreement) to unitholders as of the record date. Available cash for any quarter generally consists of all cash on hand at the end of that quarter, lessthe amount of cash reserves established by our general partner, to (i) provide for the proper conduct of our business, (ii) comply with applicable law, any ofour debt instruments or other agreements, and (iii) provide funds for distributions to our unitholders and to our general partner for any one or more of the nextfour quarters.We believe that our anticipated cash flows from operations and the borrowing capacity under our Revolving Credit Facility (as defined herein) aresufficient to meet our liquidity needs. If our plans or assumptions change or are inaccurate, or if we make acquisitions, we may need to raise additional capitalor sell assets. Our ability to raise additional capital, if necessary, depends on various factors and conditions, including market conditions. We cannot give anyassurances that we can raise additional capital to meet these needs (see Part I, Item 1A–“Risk Factors”). Commitments or expenditures, if any, we may maketoward any acquisition projects are at our discretion.91Table of ContentsUnder current market conditions, we are much less likely to pursue acquisitions than we have been in the past. We continue to undertake certaincapital expansion projects and expect to be able to finance these projects through available capacity on our Revolving Credit Facility, asset sales or otherforms of financing.Other sources of liquidity during the year ended March 31, 2018 are discussed below.DispositionsOn March 30, 2018, we sold a portion of our Retail Propane segment to DCC LPG for net proceeds of $212.4 million in cash at closing.On March 30, 2018, we completed the transaction to form a joint venture related to Sawtooth and received consideration consisting of a cashpayment of approximately $37.6 million (excluding working capital) and the contribution of certain refined products rights and adjacent leasehold. Thenoncontrolling interest owner has an option to purchase our interest in Sawtooth within the next three years. See Note 15 to our consolidated financialstatements included in this Annual report for a further discussion of this transaction.On December 22, 2017, we sold our previously held 50% interest in Glass Mountain for net proceeds of $292.1 million.Class B Preferred UnitsDuring the year ended March 31, 2018, we issued 8,400,000 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable PerpetualPreferred Units (“Class B Preferred Units”) representing limited partner interests at a price of $25.00 per unit for net proceeds of $202.7 million (net of theunderwriters’ discount of $6.6 million and offering costs of $0.7 million). See Note 10 to our consolidated financial statements included in this AnnualReport for a further description of the Class B Preferred Units.Long-Term DebtCredit AgreementWe are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks, which was amended and restated in February2017. As of March 31, 2018, the Credit Agreement includes a revolving credit facility to fund working capital needs (the “Working Capital Facility”) and arevolving credit facility to fund acquisitions and expansion projects (the “Expansion Capital Facility,” and together with the Working Capital Facility, the“Revolving Credit Facility”). Our Revolving Credit Facility includes an “accordion” feature that allows us to increase the capacity by $300 million if newlenders wish to join the syndicate or if current lenders wish to increase their commitments. The commitments under the Credit Agreement expire onOctober 5, 2021.At March 31, 2018, we were in compliance with the covenants under the Credit Agreement.Senior Secured Notes On December 29, 2017, we repurchased all of the remaining outstanding senior secured notes for $250.2 million. See Note 8 to our consolidatedfinancial statements included in this Annual Report for a further discussion of the repurchases.

Amounts for the year ended March 31, 2017primarily related to payments made to terminate a development agreement and other liabilities.We currently expect to spend approximately $250 million to $275 million on growth capital expenditures during fiscal year 2019, which includescertain acquisitions in our Water Solutions segment that we expect to close in the first quarter of our fiscal year 2019.Cash FlowsThe following table summarizes the sources (uses) of our cash flows for the periods indicated: Year Ended March 31,Cash Flows Provided by (Used in): 2018 2017 2016 (in thousands)Operating activities, before changes in operating assets and liabilities $290,396 $258,573 $221,074Changes in operating assets and liabilities (152,754) (282,813) 130,421Operating activities $137,642 $(24,240) $351,495Investing activities $270,582 $(363,126) $(445,327)Financing activities $(394,281) $371,454 $80,705Operating Activities. The seasonality of our natural gas liquids businesses has a significant effect on our cash flows from operating activities.Increases in natural gas liquids prices typically reduce our operating cash flows due to higher cash requirements to fund increases in inventories, anddecreases in natural gas liquids prices typically increase our operating cash flows due to lower cash requirements to fund increases in inventories. In ourLiquids and Retail Propane businesses, we typically experience operating losses or lower operating income during our first and second quarters, or the sixmonths ending September 30, as a result of lower volumes of natural gas liquids sales and when we are building our inventory levels for the upcomingheating season. The heating season runs through the six months ending March 31. The seasonal motor fuel blend during the third quarter of our fiscal yearimpacts the value of our gasoline inventory in our Refined Products and Renewables business and also represents a period when we build inventory into oursystem. We borrow under our Revolving Credit Facility to supplement our operating cash flows during the periods in which we are building inventory. Ouroperations, and as a result our cash flows, are also impacted by positive and negative movements in commodity prices, which cause fluctuations in the valueof inventory, accounts receivable and payables, due to increases and decreases in revenues and cost of sales. The change in net cash from operating activitiesbetween the years ended March 31, 2016, 2017 and 2018 was due primarily to higher inventory as a result of the purchase of additional pipeline capacityallocations in our Refined Products and Renewables segment during the year ended March 31, 2017.Investing Activities. Net cash provided by investing activities was $270.6 million during the year ended March 31, 2018, compared to net cash usedin investing activities of $363.1 million during the year ended March 31, 2017.

See Note 8 to our consolidatedfinancial statements included in this Annual Report for additional information on our Credit Agreement.(2)We have executed noncancelable agreements with crude oil pipeline operators, which guarantee us minimum monthly shipping capacity on the pipelines. As a result, we arerequired to pay the minimum shipping fees if actual shipments are less than our allotted capacity. Under certain agreements we have the ability to recover minimum shippingfees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during each month remaining under the agreement, with some contractscontaining provisions that allow us to continue shipping up to six months after the maturity date of the contract in order to recapture previously paid minimum shippingdelinquency fees. See Note 9 to our consolidated financial statements included in this Annual Report for additional information.(3)At March 31, 2018, construction commitments relate to the expansion of the Lucerne, Colorado crude oil tank storage.(4)Index prices are based on a forward price curve at March 31, 2018. A theoretical change of $0.10 per gallon of natural gas liquids in the underlying commodity price atMarch 31, 2018 would result in a change of $58.2 million in the value of our index-price natural gas liquids purchase commitments. A theoretical change of $1.00 per barrel ofcrude oil in the underlying commodity price at March 31, 2018 would result in a change of $61.2 million in the value of our index-price crude oil purchase commitments. SeeNote 9 to our consolidated financial statements included in this Annual Report for further detail of the commitments.(5)Our crude oil index-price purchase commitments exceed our crude oil index-price sales commitments (see Note 9 to our consolidated financial statements included in thisAnnual Report) due primarily to our long-term purchase commitments for crude oil that we purchase and ship on the Grand Mesa Pipeline. As these purchase commitmentsare deliver-or-pay contracts, we have not entered into corresponding long-term sales contracts for volumes we may not receive.97Table of ContentsOff-Balance Sheet ArrangementsWe do not have any off balance sheet arrangements other than the operating leases discussed in Note 9 to our consolidated financial statementsincluded in this Annual Report.Environmental LegislationSee Part I, Item 1–“Business–Government Regulation–Greenhouse Gas Regulation” for a discussion of proposed environmental legislation andregulations that, if enacted, could result in increased compliance and operating costs. However, at this time we cannot predict the structure or outcome of anyfuture legislation or regulations or the eventual cost we could incur in compliance.Recent Accounting PronouncementsFor a discussion of recent accounting pronouncements that are applicable to us, see Note 2 to our consolidated financial statements included in thisAnnual Report.Critical Accounting PoliciesThe preparation of financial statements and related disclosures in conformity with GAAP requires the selection and application of appropriateaccounting principles to the relevant facts and circumstances of our operations and the use of estimates made by management. We have identified thefollowing accounting policies that are most important to the portrayal of our consolidated financial position and results of operations. The application ofthese accounting policies, which requires subjective or complex judgments regarding estimates and projected outcomes of future events, and changes inthese accounting policies, could have a material effect on our consolidated financial statements.Revenue RecognitionWe record product sales revenues when title to the product transfers to the purchaser, which typically occurs when the purchaser receives theproduct. We record terminaling, transportation, storage, and service revenues when the service is performed, and we record tank and other rental revenuesover the lease term. Revenues for our Water Solutions segment are recognized when we obtain the wastewater at our treatment and disposal facilities.Derivative Financial InstrumentsWe record all derivative financial instrument contracts at fair value in our consolidated balance sheets except for certain contracts that qualify forthe normal purchase and normal sale election. Under this accounting policy election, we do not record the contracts at fair value at each balance sheet date;instead, we record the purchase or sale at the contracted value once the delivery occurs.We have not designated any financial instruments as hedges for accounting purposes. All changes in the fair value of our commodity derivativeinstruments that do not qualify as normal purchases and normal sales (whether cash transactions or non-cash mark-to-market adjustments) are reported withincost of sales in our consolidated statements of operations, regardless of whether the contract is physically or financially settled.We utilize various commodity derivative financial instrument contracts to attempt to reduce our exposure to price fluctuations. We do not enter intosuch contracts for trading purposes. Changes in assets and liabilities from commodity derivative financial instruments result primarily from changes in marketprices, newly originated transactions, and the timing of settlements. We attempt to balance our contractual portfolio in terms of notional amounts and timingof performance and delivery obligations. However, net unbalanced positions can exist or are established based on our assessment of anticipated marketmovements. Inherent in the resulting contractual portfolio are certain business risks, including commodity price risk and credit risk. Commodity price risk isthe risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response tochanging market conditions. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. Proceduresand limits for managing commodity price risks and credit risks are specified in our market risk policy and credit risk policy, respectively. Open commoditypositions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel. Credit risk ismonitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master nettingagreements that allow for offsetting counterparty receivable and payable balances for certain transactions.98Table of ContentsImpairment of Long-Lived AssetsWe evaluate the carrying value of our long-lived assets (property, plant and equipment and amortizable intangible assets) for potential impairmentwhen events and circumstances warrant such a review. A long-lived asset group is considered impaired when the anticipated undiscounted future cash flowsfrom the use and eventual disposition of the asset group is less than its carrying value. We compare the carrying value of the long-lived asset to the estimatedundiscounted future cash flows expected to be generated from that asset. Estimates of future net cash flows include estimating future volumes, future marginsor tariff rates, future operating costs and other estimates and assumptions consistent with our business plans. If we determine that an asset’s unamortized costmay not be recoverable due to impairment, we may be required to reduce the carrying value and the subsequent useful life of the asset. Any such write-downof the value and unfavorable change in the useful life of a long-lived asset would increase costs and expenses at that time.We evaluate our equity method investments for impairment when we believe the current fair value may be less than the carrying amount and recordan impairment if we believe the decline in value is other than temporary.Impairment of GoodwillGoodwill is subject to at least an annual assessment for impairment. We perform our annual assessment of impairment during the fourth quarter ofour fiscal year, and more frequently if circumstances warrant. For purposes of goodwill impairment testing, assets are grouped into “reporting units”. Areporting unit is either an operating segment or a component of an operating segment, depending on how similar the components of the operating segmentare to each other in terms of operational and economic characteristics. For each reporting unit, we perform a qualitative assessment of relevant events andcircumstances about the likelihood of goodwill impairment. If it is deemed more likely than not that the fair value of the reporting unit is less than itscarrying amount, we calculate the fair value of the reporting unit. Otherwise, further testing is not required. The qualitative assessment is based on reviewingthe totality of several factors, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, otherentity specific events (for example, changes in management) or other events such as selling or disposing of a reporting unit. The determination of a reportingunit’s fair value is predicated on our assumptions regarding the future economic prospects of the reporting unit. Such assumptions include (i) discretefinancial forecasts for the assets contained within the reporting unit, which rely on management’s estimates of operating margins, (ii) long-term growth ratesfor cash flows beyond the discrete forecast period, (iii) appropriate discount rates and (iv) estimates of the cash flow multiples to apply in estimating themarket value of our reporting units. If the fair value of the reporting unit (including its inherent goodwill) is less than its carrying value, a charge to earningsmay be required to reduce the carrying value of goodwill to its implied fair value. If future results are not consistent with our estimates, we could be exposedto future impairment losses that could be material to our results of operations. We monitor the markets for our products and services, in addition to the overallmarket, to determine if a triggering event occurs that would indicate that the fair value of a reporting unit is less than its carrying value. See Note 6 to ourconsolidated financial statements included in this Annual Report for a further discussion of our goodwill impairment assessment.Asset Retirement ObligationsWe have contractual and regulatory obligations at certain facilities for which we have to perform remediation, dismantlement, or removal activitieswhen the assets are retired. We are required to recognize the fair value of a liability for an asset retirement obligation if a reasonable estimate of fair value canbe made. In order to determine the fair value of such a liability, we must make certain estimates and assumptions including, among other things, projectedcash flows, the estimated timing of retirement, a credit-adjusted risk-free interest rate, and an assessment of market conditions, which could significantlyimpact the estimated fair value of the asset retirement obligation. These estimates and assumptions are very subjective and can vary over time. Ourconsolidated balance sheet at March 31, 2018 includes a liability of $9.1 million related to asset retirement obligations, which is reported within othernoncurrent liabilities.In addition to the obligations described above, we may be obligated to remove facilities or perform other remediation upon retirement of certainother assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates areindeterminable. We will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable.99Table of ContentsDepreciation and Amortization Methods and Estimated Useful Lives of Property, Plant and Equipment and Intangible AssetsDepreciation and amortization expense is the systematic write-off of the cost of our property, plant and equipment (net of residual or salvage value,if any) and the cost of our amortizable intangible assets to the results of operations for the quarterly and annual periods during which the assets are used. Wedepreciate our property, plant and equipment and amortize the majority of our intangible assets using the straight-line method, which results in our recordingdepreciation and amortization expense evenly over the estimated life of the individual asset. The estimate of depreciation and amortization expense requiresus to make assumptions regarding the useful economic lives and residual values of our assets. When we acquire and place our property, plant and equipmentin service or acquire intangible assets, we develop assumptions about the useful economic lives and residual values of such assets that we believe to bereasonable; however, circumstances may develop that could require us to change these assumptions in future periods, which would change our depreciationand amortization expense prospectively. Examples of such circumstances include changes in laws and regulations that limit the estimated economic life of anasset, changes in technology that render an asset obsolete, changes in expected salvage values or changes in customer attrition rates.Business CombinationsWe record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values. Fair values of assets acquiredand liabilities assumed are based upon available information and may involve engaging an independent third party to perform an appraisal. Estimating fairvalues can be complex and subject to significant business judgment. We must also identify and include in the allocation all acquired tangible and intangibleassets that meet certain criteria, including assets that were not previously recorded by the acquired entity. The estimates most commonly involve property,plant and equipment and intangible assets, including those with indefinite lives. The estimates also include the fair value of contracts including commoditypurchase and sale agreements, storage contracts, and transportation contracts. The excess of the purchase price over the net fair value of acquired assets andassumed liabilities is recorded as goodwill, which is not amortized but instead is evaluated for impairment at least annually. Pursuant to GAAP, an entity isallowed a reasonable period of time (not to exceed one year) to obtain the information necessary to identify and measure the fair value of the assets acquiredand liabilities assumed in a business combination.InventoriesOur inventories consist primarily of crude oil, natural gas liquids, gasoline, diesel, ethanol, and biodiesel. Our inventories are valued at the lower ofcost or net realizable value, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost oftransportation and storage, and with net realizable value defined as the estimated selling price in the ordinary course of business, less reasonably predictablecosts of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments and the opportunity to transferpropane inventory from our Liquids business to our Retail Propane business to sell the inventory in retail markets. At the end of each fiscal year, we alsoperform a “lower of cost or net realizable value” analysis; if the cost basis of the inventories would not be recoverable based on the net realizable value at theend of the year, we reduce the book value of the inventories to the recoverable amount. When performing this analysis during interim periods within a fiscalyear, accounting standards do not require us to record a lower of cost or net realizable value write-down if we expect the net realizable value to recover by ourfiscal year end. The net realizable values of these commodities change on a daily basis as supply and demand conditions change. We are unable to controlchanges in the net realizable value of these commodities and are unable to determine whether write-downs will be required in future periods. In addition,write-downs at interim periods could be required if we cannot conclude that net realizable values will recover sufficiently by our fiscal year end.Equity-Based CompensationOur general partner has granted certain restricted units to employees and directors under a long-term incentive plan. The restricted units include bothawards that: (i) vest contingent on the continued service of the recipients through the vesting date (the “Service Awards”) and (ii) vest contingent both on thecontinued service of the recipients through the vesting date and also on the performance of our common units relative to other entities in the Alerian MLPIndex (the “Index”) over specified periods of time (the “Performance Awards”). The awards may also vest upon a change of control, at the discretion of theboard of directors of our general partner.Service Awards are valued at the closing price as of the grant date less the present value of the expected distribution stream over the vesting periodusing a risk-free interest rate. We record the expense for each Service Award on a straight-line basis over the requisite period for the entire award (that is, overthe requisite service period of the last separately vesting100Table of Contentsportion of the award), ensuring that the amount of compensation cost recognized at any date at least equals the portion of the grant-date value of the awardthat is vested at that date.The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grant date. The significant inputs used to calculate thefair value of these awards include (i) the price per our common units at the grant date and the beginning of the performance period, (ii) a compounded risk-free interest rate, (iii) our compounded dividend yield, (iv) our historical volatility, (v) the volatility and correlations of our peers and (vi) the remainingperformance period. We record the expense for each of the tranches of the Performance Awards on a straight-line basis over the period beginning with thegrant date and ending with the vesting date of the tranche. Any Performance Awards that do not become earned Performance Awards will terminate, expireand otherwise be forfeited by the participants.Item 7A. Quantitative and Qualitative Disclosures About Market RiskInterest Rate RiskA significant portion of our long-term debt is variable-rate debt. Changes in interest rates impact the interest payments of our variable-rate debt butgenerally do not impact the fair value of the liability. Conversely, changes in interest rates impact the fair value of our fixed-rate debt but do not impact itscash flows.Our Revolving Credit Facility is variable-rate debt with interest rates that are generally indexed to bank prime or LIBOR interest rates. At March 31,2018, we had $969.5 million of outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of 4.99%. A change ininterest rates of 0.125% would result in an increase or decrease of our annual interest expense of $1.2 million, based on borrowings outstanding at March 31,2018.Commodity Price and Credit RiskOur operations are subject to certain business risks, including commodity price risk and credit risk. Commodity price risk is the risk that the marketvalue of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response to changing marketconditions. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract.Procedures and limits for managing commodity price risks and credit risks are specified in our market risk policy and credit risk policy, respectively.Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel.Credit risk is monitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into masternetting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions. At March 31, 2018, our primarycounterparties were retailers, resellers, energy marketers, producers, refiners, and dealers.The crude oil, natural gas liquids, and refined and renewables products industries are “margin-based” and “cost-plus” businesses in which grossprofits depend on the differential of sales prices over supply costs. We have no control over market conditions. As a result, our profitability may be impactedby sudden and significant changes in the price of crude oil, natural gas liquids, and refined and renewables products.We engage in various types of forward contracts and financial derivative transactions to reduce the effect of price volatility on our product costs, toprotect the value of our inventory positions, and to help ensure the availability of product during periods of short supply. We attempt to balance ourcontractual portfolio by purchasing volumes when we have a matching purchase commitment from our wholesale and retail customers. We may experiencenet unbalanced positions from time to time. In addition to our ongoing policy to maintain a balanced position, for accounting purposes we are required, onan ongoing basis, to track and report the market value of our derivative portfolio.101Table of ContentsAlthough we use financial derivative instruments to reduce the market price risk associated with forecasted transactions, we do not account forfinancial derivative transactions as hedges. We record the changes in fair value of these financial derivative transactions within cost of sales in ourconsolidated statements of operations. The following table summarizes the hypothetical impact on the March 31, 2018 fair value of our commodityderivatives of an increase of 10% in the value of the underlying commodity (in thousands): Increase(Decrease)To Fair ValueCrude oil (Crude Oil Logistics segment)$(9,943)Propane (Liquids segment)$(64)Other products (Liquids segment)$(238)Gasoline (Refined Products and Renewables segment)$(28,747)Diesel (Refined Products and Renewables segment)$(9,622)Ethanol (Refined Products and Renewables segment)$(3,207)Biodiesel (Refined Products and Renewables segment)$1,593Canadian dollars (Liquids segment)$637Fair ValueWe use observable market values for determining the fair value of our derivative instruments.

Under the supervision and with the participation of ourmanagement, including the Chief Executive Officer and Chief Financial Officer of our general partner, we conducted an evaluation of the effectiveness of ourinternal control over financial reporting based on the framework in the 2013 Internal Control-Integrated Framework issued by the Committee of SponsoringOrganizations of the Treadway Commission, or the COSO framework.102Table of ContentsBased on our evaluation under the COSO framework, our management concluded that our internal control over financial reporting was effective asof March 31, 2018.Our internal control over financial reporting as of March 31, 2018 has been audited by Grant Thornton LLP, an independent registered publicaccounting firm, as stated in their report, which appears in Part IV, Item 15 - “Exhibits, Financial Statement Schedules” in this Annual Report.Changes in Internal Control Over Financial ReportingOther than changes that have resulted or may result from our business combinations during the year ended March 31, 2018, as discussed below, therehave been no changes in our internal controls over financial reporting (as defined in Rule 13(a)-15(f) of the Exchange Act) during the three months endedMarch 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.We closed several business combinations during the year ended March 31, 2018, as described in Note 4 to our consolidated financial statementsincluded in this Annual Report. At this time, we continue to evaluate the business and internal controls and processes of these acquired businesses and aremaking various changes to their operating and organizational structure based on our business plan. We are in the process of implementing our internalcontrol structure over these acquired businesses. We expect that our evaluation and integration efforts related to those combined operations will continueinto future fiscal quarters.Item 9B. Other InformationNone.103Table of ContentsPART IIIItem 10.

Executive CompensationCompensation Discussion and AnalysisThe year “2018” in the Compensation Discussion and Analysis and the summary compensation table refers to our fiscal year ended March 31, 2018.109Table of ContentsIntroductionThe board of directors of our general partner has responsibility and authority for compensation-related decisions for our executive officers. Theboard of directors has formed a compensation committee to develop our compensation program, to determine the compensation of our Chief ExecutiveOfficer, and to make recommendations to the board of directors regarding the compensation of our other executive officers. Our executive officers are alsoofficers of our operating companies and are compensated directly by our operating companies. While we reimburse our general partner and its affiliates for allexpenses they incur on our behalf, our executive officers do not receive any additional compensation for the services they provide to our general partner.Our “named executive officers” for fiscal year 2018 were:•H. Michael Krimbill–Chief Executive Officer•Robert W. Karlovich III–Executive Vice President and Chief Financial Officer•Vincent J. Osterman–President, Retail Propane Operations•Lawrence J. Thuillier–Chief Accounting Officer•Kurston P. McMurray–Executive Vice President and General Counsel and SecretaryCompensation PhilosophyOur compensation philosophy emphasizes pay-for-performance, focused primarily on the ability to increase sustainable quarterly distributions toour unitholders. Pay-for-performance is based on a combination of our performance and the individual executive officer’s contribution to our performance.We believe this pay-for-performance approach generally aligns the interests of our executive officers with the interests of our unitholders, and at the sametime enables us to maintain a lower level of cash compensation expense in the event our operating and financial performance do not meet our expectations.Our executive compensation program is designed to provide a total compensation package that allows us to:•Attract and retain individuals with the background and skills necessary to successfully execute our business strategies;•Motivate those individuals to reach short-term and long-term goals in a way that aligns their interests with the interests of our unitholders; and•Reward success in reaching those goals.Recent AchievementsOur compensation structure is designed to reward our officers for achieving above-market returns for our unitholders. Our achievements during theyear ended March 31, 2018 included the following:•Issued 9.00% Class B Preferred Units for net proceeds of $202.7 million;•Sold our 50% interest in Glass Mountain for net proceeds of $292.1 million;•Sold a portion of our Retail Propane segment for net proceeds of $212.4 million; and•Sold a portion of our Sawtooth salt dome cavern facility for cash of $37.6 million and the contribution of certain refined products rights.Compensation Highlights•We paid cash bonuses to Mr. Karlovich and Mr. McMurray during fiscal year 2018, primarily due to their work related to the sale of our 50%interest in Glass Mountain and the sale of a portion of our Retail Propane segment.•The salaries of most of our named executive officers remain below the median of our benchmark peer group. This enables us to grant moreperformance-based compensation to maintain competitive total compensation packages.110Table of ContentsFactors Enhancing Alignment with Unitholder Interests•Majority of officer pay is at risk incentive compensation based on annual financial performance and growth in unitholder value;•Equity-based incentives are the largest single component of officer compensation;•Certain of the officers’ equity awards are subject to achievement of above-median total unitholder return relative to our performance peer group;•No excise tax gross-ups; and•Compensation committee engages an independent compensation adviser.Compensation Setting Process Our compensation program for our named executive officers supports our philosophy of pay-for-performance.•Role of Management: Our Chief Executive Officer also provides periodic recommendations to the compensation committee and the board ofdirectors regarding the compensation of our other named executive officers.•Role of the Compensation Committee’s Consultant: In carrying out its responsibilities for establishing, implementing and monitoring theeffectiveness of our executive compensation philosophy, plans and programs, our compensation committee has the authority to engage outsideexperts to assist in its deliberations. During fiscal year 2018, the compensation committee received compensation advice and data from PearlMeyer & Partners (“PM&P”). PM&P conducted a competitive review of the principal components of compensation for our executives, includingour named executive officers. PM&P also provided input on peer group selection (compensation and performance peers), and short and long-term incentive plan design. The compensation committee reviewed the services provided by PM&P and determined that they are independent inproviding executive compensation consulting services. In making this determination, the compensation committee noted that during fiscal year2018:◦PM&P did not provide any services to the Partnership or management other than compensation consulting services requested by or with theapproval of the compensation committee;◦PM&P does not provide, directly or indirectly through affiliates, any non-compensation services such as pension consulting or humanresource outsourcing;◦PM&P maintains a conflicts policy, which was provided to the compensation committee with specific policies and procedures designed toensure independence;◦Fees paid to PM&P by the Partnership during fiscal year 2018 were less than 1% of PM&P’s total revenue;◦None of the PM&P consultants working on Partnership matters had any business or personal relationship with compensation committeemembers;◦None of the PM&P consultants working on Partnership matters (or any consultants at PM&P) had any business or personal relationship withany executive officer of the Partnership; and◦None of the PM&P consultants working on Partnership matters own Partnership interests.The compensation committee continues to monitor the independence of its compensation consultant on a periodic basis. The compensationcommittee considered the recommendations provided by PM&P in the process of designing the fiscal year 2018 compensation program.111Table of ContentsElements of Executive CompensationAs part of our pay-for-performance approach to executive compensation, the compensation of our executive officers includes a significantcomponent of incentive compensation based on our performance.

In setting thebase salaries, the parties considered various factors, including the compensation needed to attract or retain the officers, the historicalcompensation of the officers, and each officer’s expected individual contribution to our performance. At the request of Mr. Krimbill, the partiesagreed that he should receive a lower base salary than our other executive officers at the time because, as our Chief Executive Officer, asignificant portion of his compensation should be performance-based, to further align his interests with the interests of our unitholders. InFebruary 2012, the base salary of Mr. Krimbill was reduced to $60,000, based on our operating and financial performance as a result of anunusually warm winter. The base salary of Mr. Krimbill was restored to $120,000 effective November 12, 2012. Effective July 1, 2014, the boardof directors increased Mr. Krimbill’s salary to $350,000, in consideration of the fact that his salary was low relative to the benchmark peer group(and remains below the 25th percentile of the peer group).

As of March 31, 2018,performance will be measured over the following periods:Vesting Date of Tranche Performance Period for TrancheJuly 1, 2018 July 1, 2015 through June 30, 2018July 1, 2019 July 1, 2016 through June 30, 2019July 1, 2020 July 1, 2017 through June 30, 2020 The following table summarizes the percentage of the maximum Performance Award units that will vest depending on the percentage of entities inthe Index that NGL outperforms: Our Relative Total Unitholder Return Percentile Ranking Payout (% of Target Units)Less than 50th percentile 0%Between the 50th and 75th percentile 50%–100%Between the 75th and 90th percentile 100%–200%Above the 90th percentile 200%The Performance Award units were granted in consideration of the fact that the base salaries and the service-based equity awards for the namedexecutive officers are in most cases below the median value for officers in their respective peer groups. The compensation committee believes that if theperformance of NGL’s common units falls below the median performance of the Index, the named executive officers should receive lower compensation thantheir peers, but that if the performance of NGL’s common units exceeds the median of the Index, the compensation of the named executive officers should beincreased.114Table of ContentsSeverance and Change in Control BenefitsWe do not provide any severance or change of control benefits to our named executive officers, other than to Mr. McMurray, who is entitled toreceive severance benefits pursuant to his employment agreement in the event of certain terminations of his employment (as described below after the“Summary Compensation Table” under the heading, “Employment Agreement with Mr. McMurray”). The board of directors has the option to accelerate thevesting of the restricted units in the event of a change in control of the Partnership, although it is not under any obligation to do so. If the board of directorswere to exercise its discretion to accelerate the vesting of restricted units upon a change in control, the value of such units would be the same as reported inthe “Outstanding Equity Awards at March 31, 2018” table below.401(k) PlanWe have established a defined contribution 401(k) plan to assist our eligible employees in saving for retirement on a tax-deferred basis. The401(k) plan permits all eligible employees, including our named executive officers, to make voluntary pre-tax contributions to the plan, subject to applicabletax limitations. For every dollar that employees contribute up to 1% of their eligible compensation (as defined in the plan), we contribute one dollar, plus 50cents for every dollar employees contribute between 1% and 6% of their eligible compensation (as defined in the plan). Our matching contributions prior toJanuary 1, 2015 vest over five years and, effective January 1, 2015, our matching contributions vest over two years.Other BenefitsWe do not maintain a defined benefit or pension plan for our executive officers, because we believe such plans primarily reward longevity ratherthan performance. We provide a basic benefits package available to substantially all full-time employees, which includes a 401(k) plan and medical, dental,vision, disability and life insurance.Other OfficersCertain officers who have leadership roles within our individual business units, but who are not executive officers, participate in formulaic bonusprograms that are based on the performance of the individual business units with which they are involved. In most cases, similar programs were in place priorto our acquisition of the businesses, and we have left the programs substantially intact.Competitive Review and Fiscal Year 2018 Compensation ProgramDuring fiscal year 2018, PM&P conducted a competitive review of our executive compensation program and provided input to the compensationcommittee regarding competitive compensation levels and compensation program design. In order to provide guidance to the compensation committeeregarding competitive rates of compensation, PM&P collected pay data from the following sources:•Compensation surveys including data from published compensation surveys representative of other energy industry and broader generalindustry companies with revenues of between $1 billion and $6 billion; and•Peer group data including pay data from 10-K and proxy filings for a group of 20 publicly traded midstream oil & gas partnerships of similarsize and scope to us.Compensation Peer Group Companies AmeriGas Partners LP NuStar Energy L.P.

As described above, the compensation committee considered thisdata in establishing salaries for fiscal year 2018 and in determining the number of Service Award and Performance Award units to grant to the namedexecutive officers.Employment AgreementsWe do not have employment agreements with any of our named executive officers, other than Mr. McMurray (as described below after the“Summary Compensation Table” under the heading, “Employment Agreement with Mr. McMurray”).Deductibility of CompensationWe believe that the compensation paid to the named executive officers is generally fully deductible for federal income tax purposes. We are alimited partnership and we do not meet the definition of a “corporation” subject to deduction limitations under Section 162(m) of the Internal Revenue Codeof 1986, as amended.Compensation Committee ReportThe compensation committee of the board of directors of our general partner has reviewed and discussed the Compensation Discussion and Analysisset forth above with management. Based on this review and discussion, the compensation committee recommended to the board of directors of our generalpartner that the Compensation Discussion and Analysis be included in this Annual Report. Members of the Compensation Committee: Stephen L. Cropper (Chairman)Bryan K. GuderianJames C. KnealeRelation of Compensation Policies and Practices to Risk ManagementOur compensation arrangements contain a number of design elements that serve to minimize the incentive for taking excessive or inappropriate riskto achieve short-term, unsustainable results. This includes using restricted unit grants as a significant element of the executive compensation, as the restrictedunits are designed to reward the executives based on the long-term performance of the Partnership. In combination with our risk management practices, we donot believe that risks arising from our compensation policies and practices for our employees are reasonably likely to have a material adverse effect on us.Compensation Committee Interlocks and Insider ParticipationDuring fiscal year 2018, Stephen L. Cropper, Bryan K. Guderian, and James C. Kneale served on the compensation committee. None of theseindividuals is an employee or an officer of our general partner. As described under Part I, Item 13–“Transactions With Related Persons,” Mr. Guderian is anexecutive officer of WPX, and we entered into certain transactions with WPX during fiscal year 2018. Shawn W. Coady was an executive officer and is still amember of the board of directors of our general partner. Dr. Coady also serves on the board of directors of HOH, a family-owned company, and in this capacityDr. Coady participates in the compensation setting process of the HOH board of directors.116Table of ContentsSummary Compensation Table for 2018The following table summarizes the compensation earned by our named executive officers for fiscal years 2016 through 2018.

The agreement has a term of five years from theeffective date, subject to automatic renewals for one-year periods thereafter unless either party provides 60 days’ notice of non-renewal of the term. Theagreement provides that Mr. McMurray will receive a base salary of no less than $250,000 per year and will be eligible to receive an annual bonus withrespect to each fiscal year of the Partnership at a target of 100% of his base salary. Mr. McMurray is also entitled to receive annual awards of unvested unitsunder the Partnership’s LTIP.In the event that Mr. McMurray’s employment is terminated by the Partnership without “cause” (as defined in his agreement), provided that heexecutes a general release of claims, Mr. McMurray is entitled to receive (i) continued payment of his base salary for 12 months following the termination, (ii)the guaranteed unit awards that would have been paid or granted to Mr. McMurray had Mr. McMurray remained employed for an additional three yearsfollowing his termination, and (iii) his target annual bonus for the performance year in which his termination occurs. Mr. McMurray would also be entitled toreceive the severance benefits described in the foregoing sentence in the event that he voluntarily resigns due to a “constructive discharge,” whichcircumstances would include (1) a reduction of Mr. McMurray’s annual base salary below $250,000 (other than an across-the-board, pro rata reduction of nomore than 10% applicable to all similarly situated executives of the Partnership) or the Partnership’s failure to provide Mr. McMurray’s elements ofcompensation, (2) the removal of Mr. McMurray from the position of Senior Vice President, General Counsel and Corporate Secretary without Mr.McMurray’s written consent, (3) any action by the Partnership that results in significant diminution of Mr. McMurray’s authority, power or responsibilities,or (4) the Partnership’s relocation of its principal place of business in Oklahoma to a location more than 50 miles from its current location. Mr. McMurray issubject to non-disclosure and intellectual property rights assignment obligations, and an obligation not to solicit customers, employees or consultants lastingduring his employment and for a period of 12 months thereafter.Restricted Unit AwardsDuring fiscal year 2018, the compensation committee granted awards for which units vest at specified dates, contingent only on the continuedservice of the recipient through the service date (the “Service Awards”) and awards that vest at specific dates, contingent on both the performance of ourcommon units relative to the performance of other entities and on the continued service of the recipient through the vesting (the “Performance Awards”).118Table of Contents2018 Grants of Plan Based Awards TableThe following table summarizes the number of restricted Service and Performance Award units granted to our named executive officers, and theirgrant date fair values: Estimated Future Payouts Under Performance Awards(1) Name Grant Date Total Number ofService Award Units Threshold(#) 50% Target(#) 100% Maximum(#) 200% Grant DateFair Value ofUnit Awards($)(2)(3)Robert W.

The number of commonunits actually received by a named executive officer with respect to a Performance Award may vary based on the Partnership’s relative TUR as compared to the TUR of theperformance peer group. The Performance Awards are described above under “Long-Term Equity Incentive Awards” in the Compensation Discussion and Analysis.(2)The disclosure reflects the aggregate grant date fair value of the Performance Awards, computed in accordance with FASB ASC Topic 718 based on probable achievement ofthe performance conditions, which is consistent with the estimate of aggregate compensation to be recognized over the service period, excluding the effect of estimatedforfeitures.(3)The fair value of the restricted Service Award units shown in the table above was calculated based on the closing market price of our common units on the grant dates, withadjustments made to reflect the fact that restricted units are not entitled to distributions during the vesting period.We record the expense for each Service Award on a straight-line basis over the requisite period for the entire award (that is, over the requisite serviceperiod of the last separately vesting portion of the award), ensuring that the amount of compensation cost recognized at any date at least equals the portion ofthe grant-date value of the award that is vested at that date. The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grantdate. The significant inputs used to calculate the fair value of these awards include (i) the price per our common units at the grant date and the beginning ofthe performance period, (ii) a compounded risk-free interest rate, (iii) our compounded dividend yield, (iv) our historical volatility, (v) the volatility andcorrelations of our peers and (vi) the remaining performance period. We record the expense for each of the tranches of the Performance Awards on a straight-line basis over the period beginning with the grant date and ending with the vesting date of the tranche. Any Performance Awards that do not become earnedPerformance Awards will terminate, expire and otherwise be forfeited by the participants. The amounts reported in the table above for restricted units andperformance units is the grant date fair value for financial reporting purposes under ASC 718 and does not represent the amount actually realized by theexecutive at vesting, which may be less or more than the amount reported in the table above.119Table of ContentsOutstanding Equity Awards at March 31, 2018The following table summarizes the number of unvested Service Awards and Performance Awards outstanding and their fair values at March 31,2018: Service Awards Performance Awards Number of Unitsthat Have Not Yet Vested Market Value of Unitsthat Have NotYet Vested Number of Unitsthat Have Not Yet Vested Market Value of Unitsthat Have NotYet VestedName (#)(1) ($)(2) (#)(3) ($)(2)H.

Inthe event that Mr. McMurray’s employment had been terminated as of March 31, 2018 by the Partnership without “cause” or due to a “constructivedischarge,” Mr. McMurray would have been entitled to receive the following amounts:Cash Severance Value of Guaranteed Unit Awards Target Annual Bonus Total$300,000 $495,000 $300,000 $1,095,000The board of directors has the option to accelerate the vesting of the restricted units in the event of a change in control of the Partnership, although itis not under any obligation to do so. If the board of directors were to exercise its discretion to accelerate the vesting of restricted units upon a change incontrol, the value of such units would be the same as reported in the “Outstanding Equity Awards at March 31, 2018” table above (in the “Market Value ofUnits that Have Not Yet Vested” columns).Pay Ratio DisclosureAs required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we areproviding the following information regarding the ratio of the annual total compensation of our Chief Executive Officer, Mr. Krimbill, to the median of theannual total compensation of our employees for our last fiscal year.For the year ended March 31, 2018:•The median of the annual total compensation of all employees (other than the Chief Executive Officer) was $38,798; and•The annual total compensation of Mr. Krimbill, as reported in the Summary Compensation Table above, was $360,891.Based on the information for the year ended March 31, 2018, the ratio of the annual total compensation of our Chief Executive Officer to the annualtotal compensation of our median employee was approximately 9 to 1.During the year ended March 31, 2018, Mr. Krimbill did not receive any Service Award or Performance Unit grants. If Mr. Krimbill had received agrant of Service Awards and Performance units on January 10, 2018 with the other named executive officers and in the amount comparable to previous grants,Mr. Krimbill’s annual total compensation would have been $3,206,053 and the ratio of the annual total compensation of our Chief Executive Officer to theannual total compensation of our median employee would have been approximately 83 to 1.To determine our median employee, we identified each individual employed by us on January 1, 2018, our determination date. As of that date, wehad 2,761 employees located in two countries. We identified the median employee by examining only base pay plus overtime for the period from January 1,2017 through December 31, 2017. We included all employees, with the exception of three employees that work in Canada, whether employed on a full-timeor part-time basis, and did not make any estimates, assumptions or adjustments to any base pay plus overtime amounts. After identifying the medianemployee, we calculated the annual total compensation for the median employee using the same methodology we use to calculate total annual compensationfor our named executive officers, as set forth in the Summary Compensation Table above.121Table of ContentsThis pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and themethodology described above. The SEC rules for identifying the median employee and calculating the pay ratio based on that employee’s annual totalcompensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions thatreflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as othercompanies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions incalculating their own pay ratios.Director CompensationOfficers or employees of our general partner and its affiliates who also serve as directors do not receive additional compensation for their service as adirector of our general partner. Each director who is not an officer or employee of our general partner or its affiliates receives the following cash compensationfor his board service:•an annual retainer of $60,000;•an annual retainer of $10,000 for the chairmen of the audit and compensation committees; and•an annual retainer of $5,000 for each member of the audit and compensation committees other than the chairman.Special committees are convened by the board of directors from time to time to review specific transactions. Compensation paid to the members ofthese committees varies depending on the transaction and the expected time commitment of the committee members.In addition, each director who is not an officer or an employee of our general partner has been granted awards of restricted units. In January 2018,such directors were granted 8,000 restricted units that vest in tranches of 4,000 units on each of February 11, 2020 and November 10, 2020.All of our directors are also reimbursed for all out-of-pocket expenses incurred in connection with attending board or committee meetings. Eachdirector is indemnified for his actions associated with being a director to the fullest extent permitted under Delaware law.Director Compensation for Fiscal Year 2018The following table summarizes the compensation earned during fiscal year 2018 by each director who is not an officer or employee of our generalpartner or its affiliates:Name Fees Earned orPaid in Cash($) Restricted UnitAwards($) Total($)James M.

Our general partner determines the amountof these expenses. In addition, our general partner owns the 0.1% general partner interest and all of the IDRs. Our general partner is entitled to receiveincentive distributions if the amount we distribute with respect to any quarter exceeds levels specified in our partnership agreement.The following table summarizes the distributions and payments to be made by us to our directors, officers, and greater than 5% owners and ourgeneral partner in connection with our ongoing operation and any liquidation.

Assuming we have sufficient available cash to pay the same quarterlydistribution on all of our outstanding units for four quarters that we paid inMay 2018 ($0.39 per unit), our general partner would receive an annualdistribution of $0.3 million on its general partner interest and incentivedistribution rights, and our directors, officers, and greater than 5% ownerswould receive an aggregate annual distribution of $80.9 million on theircommon units. If our general partner elects to reset the target distribution levels, it will beentitled to receive common units and to maintain its general partner interest.

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 LLP Tulsa, Oklahoma May 30, 2018 F-3Table of ContentsNGL ENERGY PARTNERS LP AND SUBSIDIARIESConsolidated Balance Sheets(in Thousands,

OrganizationNGL Energy Partners LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware limited partnership formed in September 2010. NGL Energy HoldingsLLC serves as our general partner. On May 17, 2011, we completed our initial public offering (“IPO”). Subsequent to our IPO, we significantly expanded ouroperations through numerous acquisitions as discussed in Note 4. At March 31, 2018, our operations include:•Our Crude Oil Logistics segment purchases crude oil from producers and transports it to refineries or for resale at pipeline injection stations,storage terminals, barge loading facilities, rail facilities, refineries, and other trade hubs, and provides storage, terminaling, trucking, marine andpipeline transportation services through its owned assets.•Our Water Solutions segment provides services for the treatment and disposal of wastewater generated from crude oil and natural gas productionand for the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, ourWater Solutions segment sells the recovered hydrocarbons that result from performing these services.•Our Liquids segment supplies natural gas liquids to retailers, wholesalers, refiners, and petrochemical plants throughout the United States and inCanada using its leased underground storage and fleet of leased railcars, markets regionally through its 21 owned terminals throughout theUnited States, and provides terminaling and storage services at its salt dome storage facility joint venture in Utah. See Note 15 for a discussionof the joint venture of our Sawtooth NGL Caverns, LLC (“Sawtooth”) business.•Our Retail Propane segment sells propane, distillates, equipment and supplies to end users consisting of residential, agricultural, commercial,and industrial customers and to certain resellers in 21 states and the District of Columbia. See Note 15 for a discussion of the sale of a portion ofour Retail Propane segment.•Our Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations, purchases refinedpetroleum and renewable products primarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedules them fordelivery at various locations throughout the country. In addition, in certain storage locations, our Refined Products and Renewables segmentmay also purchase unfinished gasoline blending components for subsequent blending into finished gasoline to supply our marketing businessas well as third parties.Recent DevelopmentsOn March 30, 2018, we sold a portion of our Retail Propane segment to DCC LPG (see Note 15). As a result, we deconsolidated this portion of ourRetail Propane segment. As this sale transaction did not represent a strategic shift that will have a major effect on our operations or financial results,operations related to this portion of our Retail Propane segment have not been classified as discontinued operations.Note 2—Significant Accounting PoliciesBasis of PresentationOur consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Theaccompanying consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and accountbalances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using theequity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, andexpenses related to this pipeline in our consolidated financial statements.Use of EstimatesThe preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amountof assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periodspresented.Critical estimates we make in the preparation of our consolidated financial statements include, among others, determining the fair value of assets andliabilities acquired in business combinations, the fair value of derivative instruments,F-9NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)the collectibility of accounts receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizableintangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation,and accruals for environmental matters. Although we believe these estimates are reasonable, actual results could differ from those estimates.Fair Value MeasurementsFair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction betweenmarket participants at the measurement date. Fair value is based upon assumptions that market participants would use when pricing an asset or liability. Weuse the following fair value hierarchy, which prioritizes valuation technique inputs used to measure fair value into three broad levels:•Level 1: Quoted prices in active markets for identical assets and liabilities that we have the ability to access at the measurement date.•Level 2: Inputs (other than quoted prices included within Level 1) that are either directly or indirectly observable for the asset or liability,including (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities ininactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, and (iv) inputs that are derived fromobservable market data by correlation or other means. Instruments categorized in Level 2 include non-exchange traded derivatives such as over-the-counter commodity price swap and option contracts and forward commodity contracts. We determine the fair value of all of our derivativefinancial instruments utilizing pricing models for similar instruments. Inputs to the pricing models include publicly available prices and forwardcurves generated from a compilation of data gathered from third parties.•Level 3: Unobservable inputs for the asset or liability including situations where there is little, if any, market activity for the asset or liability.The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs (Level3). In some cases, the inputs used to measure fair value might fall into different levels of the fair value hierarchy. The lowest level input that is significant to afair value measurement determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurementrequires judgment, considering factors specific to the asset or liability.Derivative Financial InstrumentsWe record all derivative financial instrument contracts at fair value in our consolidated balance sheets except for certain contracts that qualify forthe normal purchase and normal sale election. Under this accounting policy election, we do not record the contracts at fair value at each balance sheet date;instead, we record the purchase or sale at the contracted value once the delivery occurs.We have not designated any financial instruments as hedges for accounting purposes. All changes in the fair value of our commodity derivativeinstruments that do not qualify as normal purchases and normal sales (whether cash transactions or non-cash mark-to-market adjustments) are reported withincost of sales in our consolidated statements of operations, regardless of whether the contract is physically or financially settled.We utilize various commodity derivative financial instrument contracts to attempt to reduce our exposure to price fluctuations. We do not enter intosuch contracts for trading purposes. Changes in assets and liabilities from commodity derivative financial instruments result primarily from changes in marketprices, newly originated transactions, and the timing of settlements. We attempt to balance our contractual portfolio in terms of notional amounts and timingof performance and delivery obligations. However, net unbalanced positions can exist or are established based on our assessment of anticipated marketmovements. Inherent in the resulting contractual portfolio are certain business risks, including commodity price risk and credit risk. Commodity price risk isthe risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response tochanging market conditions. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. Proceduresand limits for managing commodity price risks and credit risks are specified in our market risk policy and credit risk policy, respectively. Open commoditypositions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel. Credit risk ismonitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master nettingagreements that allow for offsetting counterparty receivable and payable balances for certain transactions.F-10NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Revenue RecognitionWe record product sales revenues when title to the product transfers to the purchaser, which typically occurs when the purchaser receives theproduct. We record terminaling, transportation, storage, and service revenues when the service is performed, and we record tank and other rental revenuesover the lease term. Revenues for our Water Solutions segment are recognized when we obtain the wastewater at our treatment and disposal facilities.The tariffs we charge for our pipeline transportation systems are primarily regulated by the Federal Energy Regulatory Commission. Ourtariffs include provisions which allow us to deduct from our customer’s inventory a small percentage of the products our customers transport on our pipelinesystems. We refer to these product quantities as pipeline loss allowance. We receive pipeline loss allowances from our customers as consideration for productlosses during the transportation of their products on our pipeline systems. Our customers are guaranteed delivery of the amount of their injected volumes, netof pipeline loss allowance, irrespective of what our actual product losses may be during the delivery process.We report taxes collected from customers and remitted to taxing authorities, such as sales and use taxes, on a net basis. We include amounts billed tocustomers for shipping and handling costs within revenues in our consolidated statements of operations. We enter into certain contracts whereby we agree topurchase product from a counterparty and sell the same volume of product to the same counterparty at a different location or time. When such agreements areentered into at the same time and in contemplation of each other, we record the revenues for these transactions net of cost of sales.Revenues during the years ended March 31, 2018, 2017 and 2016 include $1.3 million, $4.9 million and $5.8 million, respectively, associated withthe amortization of a liability recorded in the acquisition accounting for an acquired business related to certain out-of-market revenue contracts.Cost of SalesWe include all costs we incur to acquire products, including the costs of purchasing, terminaling, and transporting inventory, prior to delivery to ourcustomers, in cost of sales. Cost of sales excludes depreciation of our property, plant and equipment.Depreciation and AmortizationDepreciation and amortization in our consolidated statements of operations includes all depreciation of our property, plant and equipment andamortization of intangible assets other than debt issuance costs, for which the amortization is recorded to interest expense, and certain contract-basedintangible assets, for which the amortization is recorded to cost of sales.Income TaxesWe qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reportshis or her share of our income or loss on his or her individual tax return. The aggregate difference in the basis of our net assets for financial and tax reportingpurposes cannot be readily determined, as we do not have access to information regarding each partner’s basis in the Partnership.We have certain taxable corporate subsidiaries in Canada, and our operations in Texas are subject to a state franchise tax that is calculated based onrevenues net of cost of sales. Our fiscal years 2014 to 2017 generally remain subject to examination by federal, state, and Canadian tax authorities. We utilizethe asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future taxconsequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which these temporary differences are expected to berecovered or settled. Changes in tax rates are recognized in income in the period that includes the enactment date.A publicly traded partnership is required to generate at least 90% of its gross income (as defined for federal income tax purposes) from certainqualifying sources. Income generated by our taxable corporate subsidiaries is excluded from this qualifying income calculation. Although we routinelygenerate income outside of our corporate subsidiaries that is non-qualifying, we believe that at least 90% of our gross income has been qualifying income foreach of the calendar years since our IPO.F-11NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)We evaluate uncertain tax positions for recognition and measurement in the consolidated financial statements. To recognize a tax position, wedetermine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals orlitigation, based on the technical merits of the position. A tax position that meets the more likely than not threshold is measured to determine the amount ofbenefit to be recognized in the consolidated financial statements. We had no material uncertain tax positions that required recognition in our consolidatedfinancial statements at March 31, 2018 or 2017.On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law by the President of the United States. The Act amendedthe Internal Revenue Code of 1986 for taxable years beginning after December 31, 2017 and does not extend retroactively to any prior tax periods. As ofMarch 31, 2018 and 2017, we do not have any deferred tax assets or liabilities. Any future deferred tax assets or liabilities will be valued based on the newcorporate tax rate under the Act.Cash and Cash EquivalentsCash and cash equivalents include cash on hand, demand and time deposits, and funds invested in highly liquid instruments with maturities of threemonths or less at the date of purchase. At times, certain account balances may exceed federally insured limits.Accounts Receivable and Concentration of Credit RiskWe operate in the United States and Canada. We grant unsecured credit to customers under normal industry standards and terms, and haveestablished policies and procedures that allow for an evaluation of each customer’s creditworthiness as well as general economic conditions. The allowancefor doubtful accounts is based on our assessment of the collectibility of customer accounts, which assessment considers the overall creditworthiness ofcustomers and any specific disputes.

Investments inpartnerships and limited liability companies, unless our investment is considered to be minor, and investments in unincorporated joint ventures are alsoaccounted for using the equity method of accounting. Under the equity method, we do not report the individual assets and liabilities of these entities on ourconsolidated balance sheets; instead, our ownership interests are reported within investments in unconsolidated entities on our consolidated balance sheets.Under the equity method, the investment is recorded at acquisition cost, increased by our proportionate share of any earnings and additional capitalcontributions and decreased by our proportionate share of any losses, distributions paid, and amortization of any excess investment. Excess investment is theamount by which our total investment exceeds our proportionate share of the net assets of the investee. We consider distributions received fromunconsolidated entities which do not exceed cumulative equity in earnings subsequent to the date of investment to be a return on investment and areclassified as operating activities in our consolidated statements of cash flows. We consider distributions received from unconsolidated entities in excess ofcumulative equity in earnings subsequent to the date of investment to be a return of investment and are classified as investing activities in our consolidatedstatements of cash flows.Our investments in unconsolidated entities consist of the following at the dates indicated: Ownership Date Acquired March 31,Entity Segment Interest (1) or Formed 2018 2017 (in thousands)Glass Mountain Pipeline, LLC (2) Crude Oil Logistics —% December 2013 $— $172,098E Energy Adams, LLC (3) Refined Products andRenewables 20% December 2013 15,142 12,952Water treatment and disposal facility (4) Water Solutions 50% August 2015 2,094 2,147Victory Propane, LLC (5) Retail Propane 50% April 2015 — 226Total $17,236 $187,423 F-13NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued) (1)Ownership interest percentages are at March 31, 2018.(2)On December 22, 2017, we sold our previously held 50% interest in Glass Mountain Pipeline, LLC for net proceeds of $292.1 million and recorded a gain on disposal of$108.6 million during the three months ended December 31, 2017 within (gain) loss on disposal or impairment of assets, net in our consolidated statement of operations.

The business purpose of Victory Propane is toacquire and/or develop retail propane operations in a defined geographic area. In conjunction with the formation of Victory Propane, we agreed to provideVictory Propane a revolving line of credit of $5.0 million to be used for working capital and/or acquisition funding. Victory Propane began using thisrevolving line of credit shortly after operations commenced. At March 31, 2018, we provided a majority of Victory Propane’s financing and have concludedthat Victory Propane is a variable interest entity because the equity is not sufficient to fund Victory Propane’s activities without additional subordinatedfinancial support. Each joint venture member has an equal ownership interest in Victory Propane and has equal representation on Victory Propane’s board ofmanagers to make all significant decisions relating to the operations of Victory Propane. Therefore, we do not have the power to direct activities thatsignificantly influence the economic performance of Victory Propane and have concluded that we are not the primary beneficiary. Our maximum exposure toloss related to Victory Propane is limited to the sum of our equity investment as shown in the table above and the outstanding loan receivable (see Note 13)at March 31, 2018.F-14NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Other Noncurrent AssetsOther noncurrent assets consist of the following at the dates indicated: March 31, 2018 2017 (in thousands)Loan receivable (1) $29,463 $40,684Line fill (2) 34,897 30,628Tank bottoms (3) 42,044 42,044Minimum shipping fees - pipeline commitments (4) 88,757 67,996Other 50,780 58,252Total $245,941 $239,604 (1)Represents the noncurrent portion of a loan receivable associated with our financing of the construction of a natural gas liquids facility to be utilized by a third party.(2)Represents minimum volumes of product we are required to leave on certain third-party owned pipelines under long-term shipment commitments.

We recover tank bottoms when the storage tanks areremoved from service. At March 31, 2018 and 2017, tank bottoms held in third party terminals consisted of 366,212 barrels and 366,212 barrels of refined products,respectively. Tank bottoms held in terminals we own are included within property, plant and equipment (see Note 5).(4)Represents the minimum shipping fees paid in excess of volumes shipped for two contracts. This amount can be recovered when volumes shipped exceed the minimummonthly volume commitment (see Note 9). Under these contracts, we currently have 2.1 years and 2.5 years, respectively, in which to ship the excess volumes.Accrued Expenses and Other PayablesAccrued expenses and other payables consist of the following at the dates indicated: March 31, 2018 2017 (in thousands)Accrued compensation and benefits $22,841 $22,227Excise and other tax liabilities 41,731 64,051Derivative liabilities 51,039 27,622Accrued interest 40,024 44,418Product exchange liabilities 11,842 1,693Deferred gain on sale of general partner interest in TLP 30,113 30,113Other 32,497 17,001Total $230,087 $207,125F-15NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Sale of General Partner Interest in TransMontaigne Partners L.P. (“TLP”)As previously reported, on February 1, 2016, we sold our general partner interest in TLP to an affiliate of ArcLight Capital Partners (“ArcLight”) fornet proceeds of $343.1 million and recorded a gain on disposal of $329.9 million during the three months ended March 31, 2016. As part of this transaction,we retained TransMontaigne Product Services LLC, including its marketing business, customer contracts and its line space on the Colonial and Plantationpipelines, which is a significant part of our Refined Products and Renewables segment. We also entered into lease agreements whereby we will remain thelong-term exclusive tenant in the TLP Southeast terminal system. As a result of entering into these leases, we deferred $204.6 million of the gain on the saleand will recognize this amount over our future lease payment obligations, which is approximately seven years (see below accounting guidance that willimpact the recognition of the deferred gain). During the years ended March 31, 2018, 2017 and 2016, we recognized $30.1 million, $30.1 million and $5.0million, respectively, of the deferred gain in our consolidated statements of operations. These gains are reported within (gain) loss on disposal or impairmentof assets, net in our consolidated statement of operations. Expected amortization of the remaining deferred gain is as follows (in thousands):Year Ending March 31, 2019$30,113202030,113202129,593202226,993202322,494Total$139,306Within our March 31, 2018 consolidated balance sheet, the current portion of the deferred gain, $30.1 million, is recorded in accrued expenses andother payables and the long-term portion, $109.2 million, is recorded in other noncurrent liabilities. See “Recent Accounting Pronouncements” below for adiscussion of the accounting for the gain upon the adoption of ASU No. 2014-09.Sale of TLP Common UnitsOn April 1, 2016, we sold all of the TLP common units we owned to ArcLight for approximately $112.4 million in cash and recorded a gain ondisposal of $104.1 million during the year ended March 31, 2017. This gain is reported within (gain) loss on disposal or impairment of assets, net in ourconsolidated statement of operations.Property, Plant and EquipmentWe record property, plant and equipment at cost, less accumulated depreciation. Acquisitions and improvements are capitalized, and maintenanceand repairs are expensed as incurred. As we dispose of assets, we remove the cost and related accumulated depreciation from the accounts, and any resultinggain or loss is included in (gain) loss on disposal or impairment of assets, net. We compute depreciation expense of our property, plant and equipment usingthe straight-line method over the estimated useful lives of the assets (see Note 5).Intangible AssetsOur intangible assets include contracts and arrangements acquired in business combinations, including customer relationships, customercommitments, pipeline capacity rights, rights-of-way and easements, executory contracts and other agreements, covenants not to compete, and trade names.In addition, we capitalize certain debt issuance costs associated with our revolving credit facilities. We amortize the majority of our intangible assets on astraight-line basis over the estimated useful lives of the assets (see Note 7). We amortize debt issuance costs over the terms of the related debt using a methodthat approximates the effective interest method.Impairment of Long-Lived AssetsWe evaluate the carrying value of our long-lived assets (property, plant and equipment and amortizable intangible assets) for potential impairmentwhen events and circumstances warrant such a review. A long-lived asset group is considered impaired when the anticipated undiscounted future cash flowsfrom the use and eventual disposition of the asset group is less than its carrying value. In that event, we recognize a loss equal to the amount by which thecarrying value exceeds the fair value of the asset group. When we cease to use an acquired trade name, we test the trade name for impairment using the reliefF-16NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)from royalty method and we begin amortizing the trade name over its estimated useful life as a defensive asset. See Note 5 and Note 7 for a further discussionof long-lived asset impairments recognized in the consolidated financial statements.We evaluate our equity method investments for impairment when we believe the current fair value may be less than the carrying amount and recordan impairment if we believe the decline in value is other than temporary.GoodwillGoodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net ofliabilities assumed. Business combinations are accounted for using the “acquisition method” (see Note 4). We expect that all of our goodwill at March 31,2018 is deductible for federal income tax purposes.Goodwill and indefinite-lived intangible assets are not amortized, but instead are evaluated for impairment at least annually. We perform our annualassessment of impairment during the fourth quarter of our fiscal year, and more frequently if circumstances warrant.To perform this assessment, we first consider qualitative factors to determine whether it is more likely than not that the fair value of each reportingunit exceeds its carrying amount. If we conclude that it is more likely than not that the fair value of a reporting unit does not exceed its carrying amount, wecalculate the fair value for the reporting unit and compare the amount to its carrying amount, including goodwill. If the fair value of a reporting unit exceedsits carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its fair value, goodwill isconsidered to be impaired and the goodwill balance is reduced by the difference between the fair value and carrying amount of the reporting unit.Estimates and assumptions used to perform the impairment evaluation are inherently uncertain and can significantly affect the outcome of theanalysis. The estimates and assumptions we used in the annual goodwill impairment assessment included market participant considerations and futureforecasted operating results. Changes in operating results and other assumptions could materially affect these estimates. See Note 6 for a further discussionand analysis of our goodwill impairment assessment.Product ExchangesQuantities of products receivable or returnable under exchange agreements are reported within prepaid expenses and other current assets and withinaccrued expenses and other payables in our consolidated balance sheets. We estimate the value of product exchange assets and liabilities based on theweighted-average cost basis of the inventory we have delivered or will deliver on the exchange, plus or minus location differentials.Advance Payments Received from CustomersWe record customer advances on product purchases as a current liability in our consolidated balance sheets.Noncontrolling InterestsNoncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. Amounts are adjusted by thenoncontrolling interest holder’s proportionate share of the subsidiaries’ earnings or losses each period and any distributions that are paid. Noncontrollinginterests are reported as a component of equity, unless the noncontrolling interest is considered redeemable, in which case the noncontrolling interest isrecorded between liabilities and equity (mezzanine or temporary equity) in our consolidated balance sheet. The redeemable noncontrolling interest isadjusted at each balance sheet date to its maximum redemption value if the amount is greater than the carrying value. The following table summarizeschanges in our redeemable noncontrolling interest in our consolidated balance sheets (in thousands):Balance at March 31, 2016 $—Transfer of redeemable noncontrolling interest 3,072Balance at March 31, 2017 3,072Net income attributable to redeemable noncontrolling interest 1,030Redeemable noncontrolling interest valuation adjustment 5,825Balance at March 31, 2018 $9,927F-17NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Business Combination Measurement PeriodWe record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values. Pursuant to GAAP, an entity isallowed a reasonable period of time (not to exceed one year) to obtain the information necessary to identify and measure the fair value of the assets acquiredand liabilities assumed in a business combination. As discussed in Note 4, certain of our acquisitions are still within this measurement period, and as a result,the acquisition date fair values we have recorded for the assets acquired and liabilities assumed are subject to change.Also, as discussed in Note 4, we made certain adjustments during the year ended March 31, 2018 to our estimates of the acquisition date fair valuesof the assets acquired and liabilities assumed in business combinations that occurred during the year ended March 31, 2017.ReclassificationsWe have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscalyear. These reclassifications did not impact previously reported amounts of assets, liabilities, equity, net income, or cash flows.Recent Accounting PronouncementsIn August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, “Statement ofCash Flows-Classification of Certain Cash Receipts and Cash Payments.” The ASU requires cash payments not made soon after the acquisition date of abusiness combination by an acquirer to settle a contingent consideration liability to be separated and classified as cash outflows for financing activities andoperating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) should be classified as financing activities and any excess should be classified as operating activities. We adopted this ASU effectiveApril 1, 2017 and have revised previously reported information.In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financialassets) measured at amortized cost to be presented at the net amount expected to be collected, which would include accounts receivable. The measurement ofexpected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportableforecasts that affect the collectibility of the reported amount. The ASU is effective for the Partnership beginning April 1, 2020, and requires a modifiedretrospective method of adoption, although early adoption is permitted. We are currently in the process of assessing the impact of this ASU on ourconsolidated financial statements.In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The ASU will replace previous lease accounting guidance in GAAP. The ASUrequires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The ASU retains a distinction betweenfinance leases and operating leases. The ASU is effective for the Partnership beginning April 1, 2019, and requires a modified retrospective method ofadoption. We are currently in the process of compiling a database of leases and analyzing each lease to assess the impact under this ASU on our consolidatedfinancial statements.In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The ASU will replace the revenue recognitionrequirements in Topic 605, “Revenue Recognition”, and most industry-specific guidance. The core principle of this ASU is that an entity should recognizerevenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU No. 2014-09 definesa five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process thanrequired under existing U.S. GAAP. In addition, the standard requires more extensive disaggregated revenue disclosures in interim and annual financialstatements.The guidance permits the use of either a full retrospective or a modified retrospective transaction approach. We adopted this standard on April 1,2018 using the modified retrospective approach. Other than discussed below, the cumulative effect of adopting the new standard was immaterial and relatedprimarily to non-cash consideration received in our Water Solutions segment. Based on our evaluation, we anticipate that from time to time, differences in thetiming of revenues earned and our right to invoice customers may create contract assets or liabilities. These differences in timing would be the result ofcontracts that contain minimum volume commitments and tiered pricing provisions, primarily within our Water SolutionsF-18NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)segment. In addition, we are in the process of implementing appropriate changes to our business processes, systems and controls to support recognition anddisclosure under this standard.As discussed above under “Sale of General Partner Interest in TLP,” we deferred a portion of the gain as this transaction was accounted for under thereal estate guidance in ASC 360-20, Property, Plant and Equipment and have been amortizing the gain over the life of the lease agreements. ASU No. 2014-09 supersedes the guidance in ASC 360-20 on determining the gain or loss recognized upon the derecognition of nonfinancial assets, including in-substancenonfinancial assets, that are not an output of an entity’s ordinary activities. This guidance is codified in ASC 610-20. ASC 610-20 does not amend orsupersede the guidance on how to determine the gain or loss on the derecognition of a subsidiary or group of assets that meets the definition of a business,which is codified in ASC 810-10-40. ASU No. 2017-05 eliminated the scope exception of “in substance real estate” from ASC 810-10-40. Therefore, upon theadoption of ASU No. 2014-09 and ASU No. 2017-05, it was determined that the transaction should be accounted for under the guidance of ASC 810-10-40and utilizing the modified retrospective approach of adoption, the deferred gain as of March 31, 2018 of $139.3 million will be recognized in the beginningbalance of retained earnings as part of our cumulative effect adjustment.Note 3—(Loss) Income Per Common UnitThe following table presents our calculation of basic and diluted weighted average units outstanding for the periods indicated: Year Ended March 31, 2018 2017 2016Weighted average units outstanding during the period: Common units - Basic 120,991,340 108,091,486 104,838,886Effect of Dilutive Securities: Performance awards — 173,087 —Warrants — 3,586,048 —Common units - Diluted 120,991,340 111,850,621 104,838,886For the year ended March 31, 2018, the Service Awards (as defined herein), Performance Awards (as defined herein), warrants and Class A PreferredUnits (as defined herein) were considered antidilutive.

Total consideration was $23.1 million, which consisted of cash of $20.0 million and thetermination of a non-compete agreement that we valued at $3.1 million, and in return we received the following:•The remaining 50% interest in NGL Solids Solutions, LLC; and•Two parcels of land to develop saltwater disposal wells.We accounted for the transaction as an acquisition of assets. Acquiring assets in groups requires not only ascertaining the cost of the asset (or netasset) group but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. The cost of a group of assetsacquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed/released based on their relative fair values and does notgive rise to goodwill or bargain purchase gains. We allocated $22.9 million to noncontrolling interest and $0.2 million to land. The acquisition of theremaining interest was accounted for as an equity transaction, no gain or loss was recorded and the carrying value of the noncontrolling interest was adjustedto reflect the change in ownership interest of the subsidiary. As of the date of the transaction, the 50% noncontrolling interest had a carrying value of $16.6million. For the termination of the non-compete agreement, we recorded a gain of $1.3 million, which included the carrying value of the non-competeagreement intangible asset that was written off (see Note 7). This gain was recorded within (gain) loss on disposal or impairment of assets, net in ourconsolidated statement of operations during the year ended March 31, 2018.Retail Propane BusinessesDuring the year ended March 31, 2018, we acquired seven retail propane businesses for total consideration of $30.9 million, of which three of thosebusinesses were part of the sale of a portion of our Retail Propane segment (see Note 15). The agreements for these acquisitions contemplate post-closingpayments for certain working capital items. We incurred and charged to general and administrative expense $0.1 million of costs related to these acquisitionsduring the year ended March 31, 2018.We are in the process of identifying and determining the fair values of the assets acquired and liabilities assumed for these retail propane businesses,and as a result, the estimates of fair value at March 31, 2018 are subject to change. The following table summarizes the preliminary estimates of the fair valuesof the assets acquired and liabilities assumed (in thousands):Current assets$2,372Property, plant and equipment11,370Goodwill2,251Intangible assets16,765Current liabilities(1,588)Other noncurrent liabilities(291)Fair value of net assets acquired$30,879Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net ofliabilities assumed. Goodwill represents a premium paid to acquire the skilled workforce of each of the businesses acquired and the ability to expand intonew markets. We expect that all of the goodwill will be deductible for federal income tax purposes.The operations of these retail propane businesses have been included in our consolidated statement of operations since their acquisition date. Ourconsolidated statement of operations for the year ended March 31, 2018 includes revenues of $17.0 million and operating income of $1.7 million that weregenerated by the operations of three of these retail propane businesses. The revenues and operating income of the other retail propane business acquisitionsare not considered material.F-20NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)The following summarizes the status of the preliminary purchase price allocation of acquisitions prior to April 1, 2017:Water Solutions FacilitiesDuring the year ended March 31, 2018, we completed the acquisition accounting for two water solutions facilities. Due to the receipt of additionalinformation, we recorded a decrease of $0.2 million to property, plant and equipment and an increase of less than $0.1 million to other noncurrent liabilitiesrelated to an asset retirement obligation. The offset of these adjustments was recorded to goodwill.Retail Propane BusinessesDuring the year ended March 31, 2018, we completed the acquisition accounting for four retail propane businesses. Due to the receipt of additionalinformation, we recorded a decrease of $0.2 million to current assets and a decrease of less than $0.1 million to property, plant and equipment. The offset ofthese adjustments was recorded to goodwill. In addition, we paid $0.4 million in cash to the sellers during the year ended March 31, 2018 for considerationthat was held back at the acquisition date, which we recorded as a liability within accrued expenses and other payables in our consolidated balance sheet.Natural Gas Liquids FacilitiesDuring the year ended March 31, 2018, we completed the acquisition accounting for certain natural gas liquids facilities acquired in January 2017.There were no material adjustments to the fair value of assets acquired and liabilities assumed during the year ended March 31, 2018.Note 5—Property, Plant and EquipmentOur property, plant and equipment consists of the following at the dates indicated: Estimated March 31,Description Useful Lives 2018 2017 (in thousands)Natural gas liquids terminal and storage assets 2-30 years $238,487 $207,825Pipeline and related facilities 30-40 years 243,616 248,582Refined products terminal assets and equipment 15-25 years 6,736 6,736Retail propane equipment 2-30 years 197,113 239,417Vehicles and railcars 3-25 years 184,273 198,480Water treatment facilities and equipment 3-30 years 601,139 557,100Crude oil tanks and related equipment 2-30 years 218,588 203,003Barges and towboats 5-30 years 92,712 91,037Information technology equipment 3-7 years 38,564 43,880Buildings and leasehold improvements 3-40 years 167,472 161,957Land 63,600 56,545Tank bottoms and line fill (1) 20,118 24,462Other 3-20 years 13,145 39,132Construction in progress 77,450 87,711 2,163,013 2,165,867Accumulated depreciation (443,066) (375,594)Net property, plant and equipment $1,719,947 $1,790,273 (1)Tank bottoms, which are product volumes required for the operation of storage tanks, are recorded at historical cost.

We estimated the fair value of our Sawtooth reporting unit based on the incomeapproach, also known as the discounted cashF-22NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)flow method, which utilizes the present value of future expected cash flows to estimate the fair value. The future cash flows of our Sawtooth reporting unitwere projected based upon estimates as of the test date of future revenues, operating expenses and cash outflows necessary to support these cash flows,including working capital and maintenance capital expenditures. We also considered expectations regarding: (i) expected storage volumes, which areassumed to increase in the coming years due to increased production of natural gas liquids, (ii) expected propane and butane prices and (iii) expected rentalfees. We assumed a 2% per year increase in commodity prices and a 4% increase in rental fees per year starting in April 2018, and held such prices and feesflat for periods in our model beyond our 2023 fiscal year. For expenses, we assumed an increase consistent with the increase in storage volumes, andmaintenance capital was held flat throughout the model. The discount rate used in our discounted cash flow method was a risk adjusted weighted averagecost of capital calculated as of September 30, 2017 of 12%. The discounted cash flow results indicated that the estimated fair value of our Sawtooth reportingunit was less than its carrying value by approximately 32% at September 30, 2017.During the three months ended September 30, 2017, we recorded a goodwill impairment charge of $116.9 million, which was recorded within (gain)loss on disposal or impairment of assets, net, in our consolidated statement of operations. At September 30, 2017, our Sawtooth reporting unit had a goodwillbalance of $66.2 million.In Note 15, we discuss a transaction in which we formed a joint venture which included our Sawtooth salt dome storage facility. As a result of thistransaction, we tested the goodwill of our Sawtooth reporting unit, immediately prior to the closing of this transaction, for impairment. As of March 30, 2018,our Sawtooth reporting unit had a goodwill balance of $66.2 million. Similar to the analysis we performed as of September 30, 2017, as discussed above, weestimated the fair value of our Sawtooth reporting unit based on the income approach, also known as the discounted cash flow method, which utilizes thepresent value of future expected cash flows to estimate the fair value. The future cash flows of our Sawtooth reporting unit were projected based uponestimates as of the test date of future revenues, operating expenses and cash outflows necessary to support these cash flows, including working capital andmaintenance capital expenditures. We also considered expectations regarding: (i) expected storage volumes, which are assumed to increase in the comingyears due to increased production of natural gas liquids, (ii) expected propane and butane prices and (iii) expected rental fees. We assumed a 2% per yearincrease in commodity prices and a 4% increase in rental fees per year starting in April 2018, and held such prices and fees flat for periods in our modelbeyond our 2023 fiscal year. For expenses, we assumed an increase consistent with the increase in storage volumes, and maintenance capital was held flatthroughout the model. The discount rate used in our discounted cash flow method was a risk adjusted weighted average cost of capital calculated as of March30, 2018 of 12.4%. The discounted cash flow results indicated that the estimated fair value of our Sawtooth reporting unit was greater than its carrying valueby approximately 2% at March 30, 2018.Our estimated fair value is predicated upon management’s assumption of the growth in the production of natural gas liquids and the decline in theuse of railcars to store natural gas liquids. We used these assumptions to estimate the demand for storage at our facility and the revenue generated bycustomers reserving capacity at our facility. Due to the current volatility in commodity prices and the excess railcars currently in the market, we believe it isreasonably possible that the need for underground storage we estimate in our model does not materialize, such that our estimate of fair value could changeand result in further impairment of the goodwill in our Sawtooth reporting unit.We performed a qualitative assessment as of January 1, 2018 to determine whether it was more likely than not that the fair value of each reportingunit was greater than the carrying value of the reporting unit. Based on these qualitative assessments, we determined that the fair value of each of thesereporting units was more likely than not greater than the carrying value of the reporting units.Fiscal Year 2017 Goodwill Impairment AssessmentWe performed a qualitative assessment as of January 1, 2017 to determine whether it was more likely than not that the fair value of each reportingunit was greater than the carrying value of the reporting unit. Based on these qualitative assessments, we determined that the fair value of each of thesereporting units was more likely than not greater than the carrying value of the reporting units.Fiscal Year 2016 Goodwill Impairment AssessmentDue to the continued decline in crude oil prices and crude oil production, we tested the goodwill within our Water Solutions reporting unit forimpairment at December 31, 2015. At December 31, 2015, our Water Solutions reporting unit had a goodwill balance of $660.8 million. We estimated the fairvalue of our Water Solutions reporting unit based on the income approach, also known as the discounted cash flow method, which utilizes the present valueof cash flows to estimate the fair value. The future cash flows of our Water Solutions reporting unit were projected based upon estimates as of the test date ofF-23NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)future revenues, operating expenses and cash outflows necessary to support these cash flows, including working capital and maintenance capitalexpenditures. We also considered expectations regarding: (i) expected disposal volumes, which have continued in spite of the lower crude oil priceenvironment as oilfield producers have focused on their most productive properties and have continued to deliver disposal volumes to our facilities, and (ii)the crude oil price environment as reflected in crude oil forward prices as of the test date. In performing the discounted cash flow analysis, we utilized reportsissued by independent third parties projecting crude oil prices through 2018. We assumed an approximate $1/barrel increase each quarter for the periodsbeyond those represented in the reports, with crude oil reaching $65/barrel by the fourth quarter of 2021. We used a price of $32/barrel for the fourth quarterof 2016, the starting point of our cash flow projections. We kept prices constant at $65/barrel for periods in our model beyond 2021. Consistent withobserved disposal volume trends, the disposal volumes were based on an expectation of a certain amount of production returning at certain crude oil pricelevels. For expenses, we assumed an increase consistent with the increase in disposal volumes. The discount rate used in our discounted cash flow methodwas calculated by using the average of the range of discount rates from a recent water solutions transaction similar in size to our Water Solutions reportingunit. The discounted cash flow results indicated that the estimated fair value of our Water Solutions reporting unit was greater than its carrying value byapproximately 9% at December 31, 2015.As a result of the continued decline in crude oil production, its continued adverse impact on our Water Solutions reporting unit and the completionof our annual budget process we decided to test the goodwill within our Water Solutions reporting unit for impairment as of March 31, 2016 as it was morelikely than not that the fair value of our Water Solutions reporting unit was less than the carrying amount. Similar to the testing performed as of December 31,2015, fair value of the Water Solutions reporting unit was based on the income approach, which utilizes the present value of cash flows to estimate the fairvalue. We utilized the same pricing, expense and discount rate assumptions in our current model as described above but adjusted our expected water volumesand percentage recovered hydrocarbons to match what we have budgeted for our fiscal year 2017. Volumes budgeted for fiscal year 2017 were heavilyinfluenced by the reporting unit’s operating results from the fourth quarter of fiscal year 2016. We utilized the same assumptions related to anticipatedvolume growth as above. The discounted cash flow results indicated that the estimated fair value of our Water Solutions reporting unit was less than itscarrying value by approximately 11% at March 31, 2016.During the year ended March 31, 2016, we recorded an estimated goodwill impairment charge of $380.2 million, which was recorded within (gain)loss on disposal or impairment of assets, net in our consolidated statements of operations. This was an initial estimate pending the completion of valuationwork being performed for us by a third party valuation firm. At March 31, 2016, our Water Solutions reporting unit had a goodwill balance of $290.9 million.During the three months ended June 30, 2016, we finalized our goodwill impairment analysis, with the assistance of a third party valuation firm. As aresult of finalizing our analysis, we determined that we needed to reverse $124.7 million of the previously recorded goodwill impairment estimate recordedduring the year ended March 31, 2016. The adjustment was due primarily to the change in the fair value of our customer relationship intangible assets. Withthe assistance of the third party valuation firm, inputs such as revenue growth rates and attrition rates related to existing customers were refined to bettercorrelate with our historical revenue growth and attrition rates of our existing customers in our Water Solutions reporting unit. This change resulted in a lowerfair value allocated to customer relationships and higher value to goodwill than in our preliminary calculation. We recorded the adjustment within (gain) losson disposal or impairment of assets, net in our consolidated statement of operations. At June 30, 2016, our Water Solutions reporting unit had a goodwillbalance of $423.7 million.For our other reporting units, we performed a qualitative assessment as of January 1, 2016 to determine whether it was more likely than not that thefair value of each reporting unit was greater than the carrying value of the reporting unit. Based on these qualitative assessments, we determined that the fairvalue of each of these reporting units was more likely than not greater than the carrying value of the reporting units.F-24NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Note 7—Intangible AssetsOur intangible assets consist of the following at the dates indicated: March 31, 2018 March 31, 2017Description AmortizableLives Gross CarryingAmount AccumulatedAmortization Net Gross CarryingAmount AccumulatedAmortization Net (in thousands)Amortizable: Customer relationships 3-20 years $882,382 $(372,944) $509,438 $906,782 $(316,242) $590,540Customer commitments 10 years 310,000 (43,917) 266,083 310,000 (12,917) 297,083Pipeline capacity rights 30 years 161,785 (17,045) 144,740 161,785 (11,652) 150,133Rights-of-way and easements 1-40 years 63,995 (3,214) 60,781 63,402 (2,154) 61,248Executory contracts and otheragreements 3-30 years 42,919 (15,424) 27,495 29,036 (20,457) 8,579Non-compete agreements 2-32 years 17,779 (7,410) 10,369 32,984 (17,762) 15,222Trade names 1-10 years 3,601 (1,909) 1,692 15,439 (13,396) 2,043Debt issuance costs (1) 5 years 40,992 (24,593) 16,399 38,983 (20,025) 18,958Total amortizable 1,523,453 (486,456) 1,036,997 1,558,411 (414,605) 1,143,806Non-amortizable: Trade names 17,485 — 17,485 20,150 — 20,150Total non-amortizable 17,485 — 17,485 20,150 — 20,150Total $1,540,938 $(486,456) $1,054,482 $1,578,561 $(414,605) $1,163,956(1)Includes debt issuance costs related to the Revolving Credit Facility (as defined herein).

As of March 31, 2018, the Credit Agreement includes a revolving credit facility to fund working capital needs (the “Working Capital Facility”) and arevolving credit facility to fund acquisitions and expansion projects (the “Expansion Capital Facility,” and together with the Working Capital Facility, the“Revolving Credit Facility”). Our Revolving Credit Facility includes an “accordion” feature that allows us to increase the capacity by $300 million if newlenders wish to join the syndicate or if current lenders wish to increase their commitments. Our Revolving Credit Facility also allows us to reallocate amountsbetween the Expansion Capital Facility and Working Capital Facility. At March 31, 2018, we had $100.0 million reallocated from the Working CapitalFacility to the Expansion Capital Facility.At March 31, 2018, the Expansion Capital Facility had a total capacity of $565.0 million for cash borrowings and the Working Capital Facility hada total capacity of $1.2 billion for cash borrowings and letters of credit. At that date, we had outstanding letters of credit of $175.7 million on the WorkingCapital Facility. Amounts outstanding for letters of credit are not recorded as long-term debt on our consolidated balance sheets, although they decrease ourborrowing capacity under the Working Capital Facility. The capacity available under the Working Capital Facility may be limited by a “borrowing base” (asdefined in the Credit Agreement), which is calculated based on the value of certain working capital items at any point in time.The commitments under the Credit Agreement expire on October 5, 2021. We have the right to prepay outstanding borrowings under the CreditAgreement without incurring any penalties, and prepayments of principal may be required if we enter into certain transactions to sell assets or obtain newborrowings. The Credit Agreement is secured by substantially all of our assets.All borrowings under the Credit Agreement bear interest, at our option, at either (i) an alternate base rate plus a margin of 0.50% to 2.00% per year or(ii) an adjusted LIBOR rate plus a margin of 1.50% to 3.00% per year. The applicable margin is determined based on our leverage ratio (as defined in theCredit Agreement). At March 31, 2018, the borrowings under the Credit Agreement had a weighted average interest rate of 4.99%, calculated as the weightedaverage LIBOR rate of 1.84% plus a margin of 3.00% for LIBOR borrowings and the prime rate of 4.75% plus a margin of 2.00% on alternate base rateborrowings. At March 31, 2018, the interest rate in effect on letters of credit was 3.00%. Commitment fees are charged at a rate ranging from 0.375% to 0.50%on any unused capacity.On June 2, 2017, we amended our Credit Agreement. The amendment modified our financial covenants. In addition, it also restricts us fromincreasing our distribution rate over the amount paid in the preceding quarter if our leverage ratio is greater than 4.25 to 1.On February 5, 2018, we amended our Credit Agreement. The amendment, among other things, amended the defined term “Consolidated EBITDA”to include the “Accrued Blenders Tax Credits” (as defined in the Credit Agreement) solely for the two quarters ended December 31, 2017 and March 31,2018.On March 6, 2018, we amended our Credit Agreement. In the amendment, the lenders consented to, subject to the consummation of the initialSawtooth disposition, release each Sawtooth entity from its guaranty and other obligations under the loan documents. In return, the Partnership agreed to usethe net proceeds of each Sawtooth disposition to pay down existing indebtedness no later than five business days after the consummation of such Sawtoothdisposition.On May 24, 2018, we amended our Credit Agreement to, among other things, modify our interest coverage ratio financial covenant for periodsbeginning March 31, 2018 and thereafter and to add a total leverage indebtedness ratio covenant, to be measured beginning March 31, 2019. Additionally,the amendment specifies that, should our leverage ratio be greater than 4.00 to 1 with respect to the quarter ended September 30, 2018, commitments underour Expansion Capital Facility will be decreased, immediately and permanently by $100.0 million.F-27NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)The following table summarizes the debt covenant levels specified in the Credit Agreement as of March 31, 2018 (as modified on May 24, 2018): Senior Secured Interest Total LeveragePeriod Beginning Leverage Ratio (1) Leverage Ratio (1) Coverage Ratio (2) Indebtedness Ratio (1)March 31, 2018 4.75 3.25 2.50 —December 31, 2018 4.75 3.25 2.75 —March 31, 2019 and thereafter 4.50 3.25 2.75 6.50 (1)Represents the maximum ratio for the period presented.(2)Represents the minimum ratio for the period presented. At March 31, 2018, our leverage ratio was approximately 4.41 to 1, our senior secured leverage ratio was approximately 0.02 to 1 and our interestcoverage ratio was approximately 2.51 to 1.The Credit Agreement contains various customary representations, warranties, and additional covenants, including, without limitation, limitationson fundamental changes and limitations on indebtedness and liens. Our obligations under the Credit Agreement may be accelerated following certain eventsof default (subject to applicable cure periods), including, without limitation, (i) the failure to pay principal or interest when due, (ii) a breach by thePartnership or its subsidiaries of any material representation or warranty or any covenant made in the Credit Agreement, or (iii) certain events of bankruptcyor insolvency.At March 31, 2018, we were in compliance with the covenants under the Credit Agreement.Senior Secured NotesOn June 19, 2012, we entered into the Note Purchase Agreement (as amended, the “Senior Secured Notes Purchase Agreement”) whereby we issued$250.0 million of senior secured notes in a private placement (the “Senior Secured Notes”). The Senior Secured Notes bear interest at a fixed rate of 6.65%which is payable quarterly. The Senior Secured Notes are required to be repaid in semi-annual installments of $25.0 million beginning on December 19, 2017and ending on the maturity date of June 19, 2022. We have the option to prepay outstanding principal, although we would incur a prepayment penalty. InDecember 2015, we amended the Senior Secured Notes Purchase Agreement to pay an additional 0.5% per year in interest if our leverage ratio exceeds 4.25to 1 plus an additional 0.5% if our leverage ratio exceeds 4.50 to 1. On August 2, 2017, we amended the Senior Secured Notes Purchase Agreement with aneffective date of June 2, 2017. The amendment, among other things, conforms the financial covenants to match the amended terms of the Credit Agreementand provides for an increase in interest charged if our leverage ratio exceeds certain predetermined levels. In addition, the amendment also restricts us fromincreasing our distribution rate over the amount paid in the preceding quarter if our interest coverage ratio is less than 3.00 to 1.

In the opinion of our management, theultimate resolution of these claims, legal actions, and complaints, after consideration of amounts accrued, insurance coverage, and other arrangements, is notexpected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters isinherently uncertain, and estimates of our liabilities may change materially as circumstances develop.Environmental MattersAt March 31, 2018, we have an environmental liability, measured on an undiscounted basis, of $2.7 million, which is recorded within accruedexpenses and other payables in our consolidated balance sheet. Our operations are subject to extensive federal, state, and local environmental laws andregulations. Although we believe our operations are in substantial compliance with applicable environmental laws and regulations, risks of additional costsand liabilities are inherent in our business, and there can be no assurance that we will not incur significant costs. Moreover, it is possible that otherdevelopments, such as increasingly stringent environmental laws, regulations and enforcement policies thereunder, and claims for damages to property orpersons resulting from the operations, could result in substantial costs. Accordingly, we have adopted policies, practices, and procedures in the areas ofpollution control, product safety, occupational health, and the handling, storage, use, and disposal of hazardous materials designed to prevent materialenvironmental or other damage, and to limit the financial liability that could result from such events. However, some risk of environmental or other damage isinherent in our business.As previously disclosed, the U.S. Environmental Protection Agency (“EPA”) had informed NGL Crude Logistics, LLC, formerly known as Gavilon,LLC (“Gavilon Energy”), of alleged violations in 2011 by Gavilon Energy of the Clean Air Act’s renewable fuel standards regulations (prior to its acquisitionby us in December 2013). On October 4, 2016, the U.S. Department of Justice, acting at the request of the EPA, filed a civil complaint in the Northern Districtof Iowa against Gavilon Energy and one of its then suppliers, Western Dubuque Biodiesel LLC (“Western Dubuque”). Consistent with the earlier allegationsby the EPA, the civil complaint related to transactions between Gavilon Energy and Western Dubuque and the generation of biodiesel renewableidentification numbers (“RINs”) sold by Western Dubuque to Gavilon Energy in 2011. On December 19, 2016, we filed a motion to dismiss the complaint.On January 9, 2017, the EPA filed an amended complaint. The amended complaint seeks an order declaring Western Dubuque’s RINs invalid and requiringthe defendants to retire an equivalent number of valid RINs and that the defendants pay statutory civil penalties. On January 23, 2017, we filed a motion todismiss the amended complaint, which was denied on May 24, 2017. On October 17, 2017, the EPA filed a motion for partial summary judgment againstGavilon Energy. Subsequently, we filed a motion for summary judgment and the EPA filed a second motion for partial summary judgment, none of whichhave yet been decided by the Court. The Court has set August 27, 2018 as the trial date for this matter. Consistent with our position against the previous EPAallegations, we deny the allegations in the amended civil complaint and that the EPA is entitled to summary judgment and we intend to continue vigorouslydefending ourselves in the civil action. However, at this time we are unable to determine the outcome of this action or its significance to us.F-31NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Asset Retirement ObligationsWe have contractual and regulatory obligations at certain facilities for which we have to perform remediation, dismantlement, or removal activitieswhen the assets are retired. Our liability for asset retirement obligations is discounted to present value. To calculate the liability, we make estimates andassumptions about the retirement cost and the timing of retirement. Changes in our assumptions and estimates may occur as a result of the passage of time andthe occurrence of future events. The following table summarizes changes in our asset retirement obligation, which is reported within other noncurrentliabilities in our consolidated balance sheets (in thousands):Balance at March 31, 2016 $5,574Liabilities incurred 1,703Liabilities assumed in acquisitions 406Liabilities settled (19)Accretion expense 517Balance at March 31, 2017 8,181Liabilities incurred 592Liabilities assumed in acquisitions 21Liabilities settled (549)Accretion expense 888Balance at March 31, 2018 $9,133In addition to the obligations described above, we may be obligated to remove facilities or perform other remediation upon retirement of certainother assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates areindeterminable. We will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable.Operating LeasesWe have executed various noncancelable operating lease agreements for product storage, office space, vehicles, real estate, railcars, and equipment.The following table summarizes future minimum lease payments under these agreements at March 31, 2018 (in thousands):Year Ending March 31, 2019$132,8612020115,962202199,312202271,038202353,273Thereafter50,061Total$522,507Rental expense relating to operating leases was $125.1 million, $124.3 million, and $125.5 million during the years ended March 31, 2018, 2017and 2016, respectively.Pipeline Capacity AgreementsWe have executed noncancelable agreements with crude oil pipeline operators, which guarantee us minimum monthly shipping capacity on thepipelines. As a result, we are required to pay the minimum shipping fees if actual shipments are less than our allotted capacity. Under certain agreements wehave the ability to recover minimum shipping fees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during eachmonth remaining under the agreement, with some contracts containing provisions that allow us to continue shipping up to six months after the maturity dateof the contract in order to recapture previously paid minimum shipping delinquency fees. We currently have an asset recorded in other noncurrent assets inour consolidated balance sheet for minimum shipping fees paid in both the current and previous periods that are expected to be recovered in future periodsby exceeding the minimum monthly volumes (see Note 2).F-32NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)The following table summarizes future minimum throughput payments under these agreements at March 31, 2018 (in thousands):Year Ending March 31, 2019$50,201202041,379Total$91,580Construction CommitmentsAt March 31, 2018, we had construction commitments of $2.7 million.Sales and Purchase ContractsWe have entered into product sales and purchase contracts for which we expect the parties to physically settle and deliver the inventory in futureperiods.At March 31, 2018, we had the following commodity purchase commitments (in thousands): Crude Oil (1) Natural Gas Liquids Value Volume(in barrels) Value Volume(in gallons)Fixed-Price Commodity Purchase Commitments: 2019 $77,015 1,230 $5,616 8,183 Index-Price Commodity Purchase Commitments: 2019 $1,403,823 23,559 $502,428 582,4562020 567,987 10,938 — —2021 453,328 9,330 — —2022 363,302 7,738 — —2023 256,327 5,482 — —Thereafter 191,010 4,112 — —Total $3,235,777 61,159 $502,428 582,456 (1)Our crude oil index-price purchase commitments exceed our crude oil index-price sales commitments (presented below) due primarily to our long-term purchase commitmentsfor crude oil that we purchase and ship on the Grand Mesa Pipeline.

The warrants have an exercise price of $0.01. During the year endedMarch 31, 2018, 607,653 warrants were exercised for common units and we received proceeds of less than $0.1 million. In addition, we repurchased 850,716unvested warrants for a total purchase price of $10.5 million on June 23, 2017. As of March 31, 2018, 2,916,743 warrants were outstanding. On April 26,2018, we repurchased outstanding warrants, asF-36NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)discussed further in Note 17, from funds managed by Oaktree, who are represented on the board of directors of our general partner.We allocated the net proceeds on a relative fair value basis to the Class A Preferred Units ($186.4 million), which includes the value of a beneficialconversion feature, and warrants ($48.6 million). As discussed below, $131.5 million of the amount allocated to the Class A Preferred Units was allocated tothe intrinsic value of the beneficial conversion feature. A beneficial conversion feature is defined as a nondetachable conversion feature that is in the moneyat the commitment date. Per the applicable accounting guidance, we are required to allocate a portion of the proceeds allocated to the Class A Preferred Unitsto the beneficial conversion feature based on the intrinsic value of the beneficial conversion feature. The intrinsic value is calculated at the commitment datebased on the difference between the fair value of the common units at the issuance date (number of common units issuable at conversion multiplied by theper unit value of our common units at the issuance date) and the proceeds attributed to the Class A Preferred Units. We record the accretion attributable to thebeneficial conversion feature as a deemed distribution using the effective interest method over the three year period prior to the effective dates of the holders’conversion right. Accretion for the beneficial conversion feature was $18.8 million and $9.0 million for the years ended March 31, 2018 and 2017,respectively.As discussed above, the Class A Preferred Units are not mandatorily redeemable but are redeemable upon a change of control, which was not certainto occur at the issuance of the Class A Preferred Units. Due to the redemption being conditioned upon an event that is not certain to occur or that is not underour control, we are required to record the value allocated to the Class A Preferred Units, excluding the value of the beneficial conversion feature, betweenliabilities and equity (mezzanine or temporary equity) in our consolidated balance sheet. The value allocated to the warrants and the beneficial conversionfeature was recorded within Limited Partners’ equity in our consolidated balance sheet.Class B Preferred UnitsDuring the year ended March 31, 2018, we issued 8,400,000 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable PerpetualPreferred Units (“Class B Preferred Units”) representing limited partner interests at a price of $25.00 per unit for net proceeds of $202.7 million (net of theunderwriters’ discount of $6.6 million and offering costs of $0.7 million).At any time on or after July 1, 2022, we may redeem our Class B Preferred Units, in whole or in part, at a redemption price of $25.00 per Class BPreferred Unit plus an amount equal to all accumulated and unpaid distributions to, but not including, the date of redemption, whether or not declared. Wemay also redeem the Class B Preferred Units upon a change of control as defined in our partnership agreement. If we choose not to redeem the Class BPreferred Units, the Class B preferred unitholders may have the ability to convert the Class B Preferred Units to common units at the then applicableconversion rate. Class B preferred unitholders have no voting rights except with respect to certain matters set forth in our partnership agreement.Distributions on the Class B Preferred Units are payable on the 15th day of each January, April, July and October of each year to holders of record onthe first day of each payment month. The initial distribution rate for the Class B Preferred Units from and including the date of original issue to, but notincluding, July 1, 2022 is 9.00% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). On and after July 1, 2022,distributions on the Class B Preferred Units will accumulate at a percentage of the $25.00 liquidation preference equal to the applicable three-month LIBORplus a spread of 7.213%.The following table summarizes distributions declared on our Class B Preferred Units during the last fiscal year:Date Declared Record Date Date Paid Amount Paid to Class BPreferred Unitholders (in thousands)September 18, 2017 September 29, 2017 October 16, 2017 $5,670December 19, 2017 December 29, 2017 January 15, 2018 $4,725March 19, 2018 April 2, 2018 April 16, 2018 $4,725The distribution amount paid on April 16, 2018 is included in accrued expenses and other payables in our consolidated balance sheet at March 31,2018.F-37NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Amended and Restated Partnership AgreementOn June 13, 2017, NGL Energy Holdings LLC executed the Fourth Amended and Restated Agreement of Limited Partnership. The preferences,rights, powers and duties of holders of the Class B Preferred Units are defined in the amended and restated partnership agreement. The Class B Preferred Unitsrank senior to the common units, with respect to the payment of distributions and distribution of assets upon liquidation, dissolution and winding up, and areon parity with the Class A Preferred Units. The Class B Preferred Units have no stated maturity but we may redeem the Class B Preferred Units at any time onor after July 1, 2022 or upon the occurrence of a change in control.On June 24, 2016, NGL Energy Holdings LLC executed the Third Amended and Restated Agreement of Limited Partnership. The preferences, rights,powers and duties of holders of the Class A Preferred Units are defined in the amended and restated partnership agreement. The Class A Preferred Units ranksenior to the common units, with respect to the payment of distributions and distribution of assets upon liquidation, dissolution and winding up. The Class APreferred Units have no stated maturity and are not subject to mandatory redemption or any sinking fund and will remain outstanding indefinitely unlessredeemed by the Partnership or converted into common units at the election of the Partnership or the Class A preferred unitholders or in connection with achange of control.Equity-Based Incentive CompensationOur general partner has adopted a long-term incentive plan (“LTIP”), which allows for the issuance of equity-based compensation. Our generalpartner has granted certain restricted units to employees and directors, which vest in tranches, subject to the continued service of the recipients. The awardsmay also vest upon a change of control, at the discretion of the board of directors of our general partner. No distributions accrue to or are paid on therestricted units during the vesting period.The restricted units include both awards that: (i) vest contingent on the continued service of the recipients through the vesting date (the “ServiceAwards”) and (ii) vest contingent both on the continued service of the recipients through the vesting date and also on the performance of our common unitsrelative to other entities in the Alerian MLP Index (the “Index”) over specified periods of time (the “Performance Awards”).During the three months ended September 30, 2016, we changed our process for how taxes are withheld upon the vesting of restricted units.Previously, employees could choose to pay cash for their portion of the taxes or have us withhold enough units to meet their tax withholding requirements.Employees could also elect to have the units withheld to exceed the statutory minimums. Now, employees will still be able to pay cash to satisfy their taxobligation or they can elect to sell enough units, through a broker assisted cashless exercise program, to meet their tax obligation. As a result of this changein process, the unvested restricted units and future grants are eligible for equity classification. Prior to this change in process, we classified any ServiceAwards or Performance Awards granted as liabilities and were required to recalculate the fair value of the award at each reporting date. Awards classified asequity are valued only at their grant date and are not revalued at each reporting date.On April 1, 2017, we made an accounting policy election to account for actual forfeitures, rather than estimate forfeitures each period (as previouslyrequired). As a result, the cumulative effect adjustment, which represents the differential between the amount of compensation expense previously recordedand the amount that would have been recorded without assuming forfeitures, had no impact on our consolidated financial statements.F-38NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)The following table summarizes the Service Award activity during the years ended March 31, 2018, 2017 and 2016:Unvested Service Award units at March 31, 2015 2,260,400Units granted 1,484,412Units vested and issued (844,626)Units withheld for employee taxes (464,054)Units forfeited (139,000)Unvested Service Award units at March 31, 2016 2,297,132Units granted 3,124,600Units vested and issued (2,350,082)Units forfeited (363,150)Unvested Service Award units at March 31, 2017 2,708,500Units granted 1,964,911Units vested and issued (2,260,011)Units forfeited (134,525)Unvested Service Award units at March 31, 2018 2,278,875In connection with the vesting of certain restricted units during year ended March 31, 2018, we canceled 57,498 of the newly-vested common unitsin satisfaction of $0.8 million of employee tax liability paid by us. Pursuant to the terms of the LTIP, these canceled units are available for future grants underthe LTIP.The following table summarizes the scheduled vesting of our unvested Service Award units at March 31, 2018:Year Ending March 31, Number of Units2019 935,9752020 969,4752021 373,425Total 2,278,875Service Awards are valued at the closing price as of the grant date less the present value of the expected distribution stream over the vesting periodusing a risk-free interest rate. We record the expense for each Service Award on a straight-line basis over the requisite period for the entire award (that is, overthe requisite service period of the last separately vesting portion of the award), ensuring that the amount of compensation cost recognized at any date at leastequals the portion of the grant-date value of the award that is vested at that date.In December 2017, the compensation committee of the board of directors of our general partner decided that the vesting of all future grants would besplit so that half of the award will vest in February and the other half will vest in November instead of the entire grant vesting in July, which was the monththe units generally vested. In addition, employees with unvested Service Awards were given an option to switch the vesting of their outstanding ServiceAwards and split the awards to vest in February and November or keep the vesting in July. For example, if an employee elected to change the vesting of theiroutstanding Service Awards, an award that was originally scheduled to vest in July 2018 would now be split so that half of the award will vest in February2018 and the other half in November 2018. The Service Awards of individuals that elected to split the vesting are considered to be modified. The impact ofthe modification was not material to the current or future unit based compensation expense.During the years ended March 31, 2018, 2017 and 2016, we recorded compensation expense related to Service Award units of $16.2 million, $56.2million and $35.2 million, respectively.Of the restricted units granted and vested during the year ended March 31, 2018, 964,702 units were granted as a bonus for performance during thefiscal year ended March 31, 2017. The total amount of these bonus payments was $12.4 million, of which we had accrued $5.5 million as of March 31, 2017.Also, 59,393 units were granted and vested as incentive compensation for the fiscal year ended March 31, 2018. The value of these awards was $0.7 millionand was recorded within general and administrative expense in our consolidated statement of operations for the year ended March 31, 2018.Of the restricted units granted and vested during the year ended March 31, 2017, 1,008,091 units were granted as a bonus for performance during theyear ended March 31, 2016. We accrued expense of $16.8 million during the year endedF-39NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)March 31, 2016 as an estimate of the value of such bonus units that would be granted. During the year ended March 31, 2017, we recorded an additional $2.2million to true up the estimate to the $19.0 million of actual expense associated with these bonuses. Since the units were not granted until August 2016, thefull $19.0 million is reflected in the expense during the year ended March 31, 2017.The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at March 31, 2018 (inthousands):Year Ending March 31, 2019 $12,4732020 6,6442021 2,081Total $21,198During April 2015, our general partner granted Performance Award units to certain employees. The number of Performance Award units that will vestis contingent on the performance of our common units relative to the performance of the other entities in the Index. Performance will be calculated based onthe return on our common units (including changes in the market price of the common units and distributions paid during the performance period) relative tothe returns on the common units of the other entities in the Index. As of March 31, 2018, performance will be measured over the following periods:Vesting Date of Tranche Performance Period for TrancheJuly 1, 2018 July 1, 2015 through June 30, 2018July 1, 2019 July 1, 2016 through June 30, 2019July 1, 2020 July 1, 2017 through June 30, 2020The following table summarizes the percentage of the maximum Performance Award units that will vest depending on the percentage of entities inthe Index that NGL outperforms:Our Relative Total Unitholder Return Percentile Ranking Payout (% of Target Units)Less than 50th percentile 0%Between the 50th and 75th percentile 50%–100%Between the 75th and 90th percentile 100%–200%Above the 90th percentile 200%The following table summarizes the Performance Award activity during the years ended March 31, 2018, 2017 and 2016:Unvested Performance Award units at March 31, 2015 —Units granted 1,041,073Units vested and issued (349,691)Units forfeited (54,000)Unvested Performance Award units at March 31, 2016 637,382Units granted 932,309Units forfeited (380,691)Unvested Performance Award units at March 31, 2017 1,189,000Units granted 224,000Units forfeited (496,000)Unvested Performance Award units at March 31, 2018 917,000During the July 1, 2014 through June 30, 2017 performance period, the return on our common units was below the return of the 50th percentile ofour peer companies in the Index. As a result, no Performance Award units vested on July 1, 2017 and performance units with the July 1, 2017 vesting date areconsidered to be forfeited.The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grant date. The significant inputs used to calculate thefair value of these awards include (i) the price per our common units at the grant dateF-40NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)and the beginning of the performance period, (ii) a compounded risk-free interest rate, (iii) our compounded dividend yield, (iv) our historical volatility, (v)the volatility and correlations of our peers and (vi) the remaining performance period. We record the expense for each of the tranches of the PerformanceAwards on a straight-line basis over the period beginning with the grant date and ending with the vesting date of the tranche. Any Performance Awards thatdo not become earned Performance Awards will terminate, expire and otherwise be forfeited by the participants. During the years ended March 31, 2018,2017 and 2016, we recorded compensation expense related to Performance Award units of $5.3 million, $7.2 million and $16.4 million, respectively.The following table summarizes the estimated future expense we expect to record on the unvested Performance Award units at March 31, 2018 (inthousands):Year Ending March 31, 2019 $4,2002020 1,9872021 406Total $6,593The number of common units that may be delivered pursuant to awards under the LTIP is limited to 10% of our issued and outstanding commonunits. The maximum number of common units deliverable under the LTIP automatically increases to 10% of the issued and outstanding common unitsimmediately after each issuance of common units, unless the plan administrator determines to increase the maximum number of units deliverable by a lesseramount. Units withheld to satisfy tax withholding obligations are not considered to be delivered under the LTIP. In addition, when an award is forfeited,canceled, exercised, paid or otherwise terminates or expires without the delivery of units, the units subject to such award are again available for new awardsunder the LTIP. At March 31, 2018, approximately 1.3 million common units remain available for issuance under the LTIP.Note 11—Fair Value of Financial InstrumentsOur cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other current assets and liabilities (excludingderivative instruments) are carried at amounts which reasonably approximate their fair values due to their short-term nature.Commodity DerivativesThe following table summarizes the estimated fair values of our commodity derivative assets and liabilities reported in our consolidated balancesheet at the dates indicated: March 31, 2018 March 31, 2017 DerivativeAssets DerivativeLiabilities DerivativeAssets DerivativeLiabilities (in thousands)Level 1 measurements $5,093 $(20,186) $2,590 $(21,113)Level 2 measurements 48,752 (54,410) 38,729 (27,799) 53,845 (74,596) 41,319 (48,912) Netting of counterparty contracts (1) (2,922) 2,922 (1,508) 1,508Net cash collateral (held) provided (1,762) 17,263 (1,035) 19,604Commodity derivatives $49,161 $(54,411) $38,776 $(27,800) (1)Relates to commodity derivative assets and liabilities that are expected to be net settled on an exchange or through a netting arrangement with the counterparty.The following table summarizes the accounts that include our commodity derivative assets and liabilities in our consolidated balance sheets at thedates indicated: March 31, 2018 2017 (in thousands)Prepaid expenses and other current assets $49,161 $38,711Other noncurrent assets — 65Accrued expenses and other payables (51,039) (27,622)Other noncurrent liabilities (3,372) (178)Net commodity derivative (liability) asset $(5,250) $10,976The following table summarizes our open commodity derivative contract positions at the dates indicated.

We paid Victory Propane $6.4 million in cash and received current assets, property, plant and equipment andcustomers. The allocation of the consideration was as follows:Current assets$276Property, plant and equipment1,366Intangible assets (customer relationships)4,782Fair value of net assets acquired$6,424Victory Propane recognized a gain on this transaction. As all intra-entity profits and losses are eliminated between an investor and investee untilrealized, we have eliminated our proportionate share of the gain from this transaction on our books. As a result, our underlying equity in the net assets ofVictory Propane exceeds our investment (see Note 2), and this difference will be amortized as income over the remaining life of the noncurrent assetsacquired or until they are sold.Victory Propane used a portion of the proceeds to pay off the outstanding balance of their note payable to us of $4.2 million and paid $2.0 millionin distributions to the owners, including us.GrasslandWe previously had a loan receivable from Grassland Water Solutions, LLC (“Grassland”) and during the three months ended June 30, 2016, wereceived loan payments of $0.7 million from Grassland in accordance with the loan agreement. On June 3, 2016, we acquired the remaining 65% ownershipinterest in Grassland. Prior to the completion of this transaction, we accounted for our previously held 35% ownership interest in Grassland using the equitymethod of accounting. As we owned a controlling interest in Grassland, we revalued our previously held 35% ownership interest to fair value of $0.8 millionand recorded a loss of $14.9 million. As the amount paid (cash plus the fair value of our previously held ownership interest) was less than the fair value of theassets acquired and liabilities assumed, we recorded a bargain purchase gain of $0.6 million. Once we acquired the remaining ownership interest in Grassland,the loan receivable was eliminated as Grassland was consolidated in our consolidated financial statements. As a result of the acquisition, we incurred animpairment charge of $1.7 million to write down the loan receivable to its fair value, which was reported within (gain) loss on disposal or impairment ofassets, net in our consolidated statement of operations. On November 29, 2016, we sold Grassland and received proceeds of $22.0 million and recorded a losson disposal of $2.3 million during the three months ended December 31, 2016. This loss is reported within (gain) loss on disposal or impairment of assets, netin our consolidated statement of operations.Note 14—Employee Benefit PlanWe have established a defined contribution 401(k) plan to assist our eligible employees in saving for retirement on a tax-deferred basis. The401(k) plan permits all eligible employees to make voluntary pre-tax contributions to the plan, subject to applicable tax limitations. For every dollar thatemployees contribute up to 1% of their eligible compensation (as defined in the plan), we contribute one dollar, plus 50 cents for every dollar employeescontribute between 1% and 6% of their eligible compensation (as defined in the plan). Our matching contributions prior to January 1, 2015 vest over fiveyears and, effective January 1, 2015, our matching contributions vest over two years. Expenses under the plan for the years ended March 31, 2018, 2017 and2016 were $3.6 million, $3.4 million and $4.2 million, respectively.Note 15—Other MattersSale of a Portion of Retail Propane BusinessOn March 30, 2018, we sold a portion of our Retail Propane segment to DCC LPG for net proceeds of $212.4 million in cash at closing, and recordeda gain on disposal of $89.3 million during the year ended March 31, 2018. This gain is reported within (gain) loss on disposal or impairment of assets, net inour consolidated statement of operations. The Retail Propane businesses subject to this transaction consisted of our operations across the Mid-Continent andWestern portions of the United States, including three of the seven retail propane businesses we acquired during the year ended March 31, 2018. We retainedour Retail Propane businesses located in the Eastern, mid-Atlantic and Southeastern sections of the United States.As this sale transaction did not represent a strategic shift that will have a major effect on our operations or financial results, operations related to thisportion of our Retail Propane segment have not been classified as discontinued operations.F-46NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)The Retail Propane businesses subject to this transaction had income before taxes of $20.0 million during the year ended March 31, 2018.Sawtooth Joint VentureOn March 30, 2018, we completed the transaction to form a joint venture with Magnum Liquids, LLC, a portfolio company of Haddington VenturesLLC, along with Magnum Development, LLC and other Haddington-sponsored investment entities (collectively “Magnum”) to focus on the storage ofnatural gas liquids and refined products by combining our Sawtooth salt dome storage facility with Magnum’s refined products rights and adjacent leasehold.Magnum acquired an approximately 28.5% interest in Sawtooth from us, in exchange for consideration consisting of a cash payment of approximately $37.6million (excluding working capital) and the contribution of certain refined products rights and adjacent leasehold, which we valued at $21.6 million andrecorded within intangible assets in our consolidated balance sheet. The disposition of this interest was accounted for as an equity transaction, no gain or losswas recorded and the carrying value of the noncontrolling interest was adjusted to reflect the change in ownership interest of the subsidiary. We ownapproximately 71.5% of the joint venture; and within the next three years, Magnum has options to acquire our remaining interest for an additional $182.4million.Termination of a Storage Sublease AgreementDuring the year ended March 31, 2017, we agreed to terminate a storage sublease agreement that was scheduled to commence in January 2017 andhad a term of five years. For terminating this agreement, the counterparty agreed to pay us a specific amount in five equal payments which began in February2017 and in January of the next four years and removed any future obligations of the Partnership. As a result, we discounted the future payments and recordeda gain of $16.2 million to other income, net in our consolidated statement of operations during the year ended March 31, 2017.Termination of Development AgreementOn June 3, 2016, we entered into a purchase and sale agreement with the counterparty to the development agreement in our Water Solutionssegment. Total cash consideration paid under the agreement was $49.6 million and in return we received the following:•Termination of the development agreement (see Note 7);•Additional interest in the water pipeline company we acquired in January 2016;•Release of contingent consideration liabilities attributed to certain of our water treatment and disposal facilities;•Certain parcels of land and permits to develop saltwater disposal wells and other parcels of land containing water wells and equipment; and•A two-year non-compete agreement with the counterparty.We accounted for the transaction as an acquisition of assets. Acquiring assets in groups requires not only ascertaining the cost of the asset (or netasset) group but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. The cost of a group of assetsacquired in an asset acquisition shall be allocated to the individual assets acquired or liabilities assumed/released based on their relative fair values and shallnot give rise to goodwill or bargain purchase gains. We allocated $1.2 million of the total consideration to property, plant and equipment, $3.3 million tointangible assets, $2.8 million to noncontrolling interest, $25.5 million to the release of contingent consideration liabilities and $16.9 million to thetermination of the development agreement. We recorded a $21.3 million gain on the release of $46.8 million of contingent consideration liabilities, whichwas recorded within (loss) gain on early extinguishment of liabilities, net in our consolidated statement of operations during the year ended March 31, 2017.For the termination of the development agreement, we recorded a loss of $22.7 million, which included the carrying value of the development agreementasset that was written off (see Note 7). This loss was recorded within (gain) loss on disposal or impairment of assets, net in our consolidated statement ofoperations during the year ended March 31, 2017.Note 16—Quarterly Financial Data (Unaudited)The following tables summarize our unaudited quarterly financial data. The computation of net income (loss) per common unit is done separately byquarter and year. The total of net income (loss) per common unit of the individual quarters may not equal net income (loss) per common unit for the year, dueprimarily to the income allocation between the general partner and limited partners and variations in the weighted average units outstanding used incomputing such amounts.F-47NGL ENERGY PARTNERS LP AND SUBSIDIARIESNotes to Consolidated Financial Statements (Continued)Our Retail Propane segment’s business is seasonal due to weather conditions in our service areas. Propane sales to residential and commercialcustomers are affected by winter heating season requirements, which generally results in higher operating revenues and net income during the period fromOctober through March of each year and lower operating revenues and either net losses or lower net income during the period from April throughSeptember of each year. Our Liquids segment is also subject to seasonal fluctuations, as demand for propane and butane is typically higher during the wintermonths. Our operating revenues from our other segments are less weather sensitive. Additionally, the acquisitions described in Note 4 impact thecomparability of the quarterly information within the year, and year to year.
