Forward-Looking Statements

This Quarterly Report on Form 10-Q (“Quarterly Report”) contains various forward-looking statements and information that are based on our beliefs and those of our general partner, as well as assumptions made by and information currently available to us. These forward-looking statements are identified as any statement that does not relate strictly to historical or current facts. Certain words in this Quarterly Report such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “may,” “plan,” “project,” “will,” and similar expressions and statements regarding our plans and objectives for future operations, identify forward-looking statements. Although we and our general partner believe such forward-looking statements are reasonable, neither we nor our general partner can assure they will prove to be correct. Forward-looking statements are subject to a variety of risks, uncertainties and assumptions. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those expected. Among the key risk factors that may affect our consolidated financial position and results of operations are:

• the prices of crude oil, natural gas liquids, gasoline, diesel, ethanol, and biodiesel;

• energy prices generally;

• the general level of crude oil, natural gas, and natural gas liquids production;

• the general level of demand, and the availability of supply, for crude oil, natural gas liquids, gasoline, diesel, ethanol, and biodiesel;

• the level of crude oil and natural gas drilling and production in areas where we have water treatment and disposal facilities;

• the prices of propane and distillates relative to the prices of alternative and competing fuels;

• the price of gasoline relative to the price of corn, which affects the price of ethanol;

• the ability to obtain adequate supplies of products if an interruption in supply or transportation occurs and the availability of capacity to transport products to market areas;

• actions taken by foreign oil and gas producing nations;

• the political and economic stability of foreign oil and gas producing nations;

• the effect of weather conditions on supply and demand for crude oil, natural gas liquids, gasoline, diesel, ethanol, and biodiesel;

• the effect of natural disasters, lightning strikes, or other significant weather events;

• the availability of local, intrastate, and interstate transportation infrastructure with respect to our truck, railcar, and barge transportation services;

• the availability, price, and marketing of competing fuels;

• the effect of energy conservation efforts on product demand;

• energy efficiencies and technological trends;

• governmental regulation and taxation;

• the effect of legislative and regulatory actions on hydraulic fracturing, wastewater disposal, and the treatment of flowback and produced water;

• hazards or operating risks related to transporting and distributing petroleum products that may not be fully covered by insurance;

• the maturity of the crude oil, natural gas liquids, and refined products industries and competition from other marketers;

• loss of key personnel;

• the ability to renew contracts with key customers;

• the ability to maintain or increase the margins we realize for our terminal, barging, trucking, wastewater disposal, recycling, and discharge services;

• the ability to renew leases for our leased equipment and storage facilities;

• the nonpayment or nonperformance by our counterparties;

1

• the availability and cost of capital and our ability to access certain capital sources;

• a deterioration of the credit and capital markets;

• the ability to successfully identify and complete accretive acquisitions, and integrate acquired assets and businesses;

• changes in the volume of hydrocarbons recovered during the wastewater treatment process;

• changes in the financial condition and results of operations of entities in which we own noncontrolling equity interests;

• changes in applicable laws and regulations, including tax, environmental, transportation, and employment regulations, or new interpretations by regulatory agencies concerning such laws and regulations and the effect of such laws and regulations (now existing or in the future) on our business operations;

• the costs and effects of legal and administrative proceedings;

• any reduction or the elimination of the federal Renewable Fuel Standard; and

• changes in the jurisdictional characteristics of, or the applicable regulatory policies with respect to, our pipeline assets.

You should not put undue reliance on any forward-looking statements. All forward-looking statements speak only as of the date of this Quarterly Report. Except as may be required by state and federal securities laws, we undertake no obligation to publicly update or revise any forward-looking statements as a result of new information, future events, or otherwise.

Notes to Unaudited Condensed Consolidated Financial Statements

Note 1—Organization and Operations

NGL Energy Partners LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware limited partnership. NGL Energy Holdings LLC serves as our general partner.AtJune 30, 2018, our operations included:

• 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 and pipeline 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 production and for the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, our Water Solutions segment sells the recovered hydrocarbons that result from performing these services and it also sells freshwater to producers for exploration and production activities.

• Our Liquids segment supplies natural gas liquids to retailers, wholesalers, refiners, and petrochemical plants throughout the United States and in Canada using its leased underground storage and fleet of leased railcars, markets regionally through its21owned terminals throughout the United States, and provides terminaling and storage services at its salt dome storage facility joint venture in Utah.

• 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 in21states and the District of Columbia. See below for a discussion of the sale of our Retail Propane segment.

• Our Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations, purchases refined petroleum and renewable products primarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedules them for delivery at various locations throughout the country. In addition, in certain storage locations, our Refined Products and Renewables segment may also purchase unfinished gasoline blending components for subsequent blending into finished gasoline to supply our marketing business as well as third parties.

Recent Developments

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment to Superior Plus Corp. (“Superior”) for total consideration of $896.5 million in cash after adjusting for estimated working capital. Accordingly, upon satisfaction of the significant closing conditions for this transaction during the month of June 2018, the assets, liabilities and redeemable noncontrolling interest of the Retail Propane segment were classified as held for sale in our unaudited condensed consolidated balance sheets. This sale included all three of the retail propane businesses we acquired during the three months ended June 30, 2018 (see Note 4). We retained our 50% ownership interest in Victory Propane, LLC (“Victory Propane”) (see Note 2). This transaction, combined with the sale of a portion of our Retail Propane segment to DCC LPG (“DCC”) on March 30, 2018, represents a strategic shift in our operations and will have a significant effect on our operations and financial results going forward. Accordingly, the results of operations and cash flows related to the entire Retail Propane segment have been classified as discontinued operations for all periods presented and prior periods have been retrospectively adjusted in the unaudited condensed consolidated statements of operations and unaudited condensed consolidated statements of cash flows.

Note 2—Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and account balances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, and expenses related to this pipeline in our unaudited condensed consolidated financial statements.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim consolidated financial information in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the unaudited condensed consolidated financial statements exclude certain information and notes required by GAAP for complete annual consolidated financial statements. However, we believe that the disclosures made are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements include all adjustments that we consider necessary for a fair presentation of our consolidated financial position, results of operations and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed in this Quarterly Report. The unaudited condensed consolidated balance sheet at March 31, 2018 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2018 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 30, 2018 and adjusted retrospectively for the Retail Propane segment disposition as previously described.

These interim unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report. Due to the seasonal nature of certain of our operations and other factors, the results of operations for interim periods are not necessarily indicative of the results of operations to be expected for future periods or for the full fiscal year ending March 31, 2019.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amount of assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periods presented.

Critical estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the fair value of assets and liabilities acquired in business combinations, the fair value of derivative instruments, the collectibility of accounts receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation, accruals for environmental matters and estimating certain revenues. Although we believe these estimates are reasonable, actual results could differ from those estimates.

Significant Accounting Policies

Our significant accounting policies are consistent with those disclosed in Note 2 of our audited consolidated financial statements included in our Annual Report.

Fair Value Measurements

Fair 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 between market participants at the measurement date. Fair value is based upon assumptions that market participants would use when pricing an asset or liability. We use 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 in inactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, and (iv) inputs that are derived from observable 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 derivative financial instruments utilizing pricing models for similar instruments. Inputs to the pricing models include publicly available prices and forward curves generated from a compilation of data gathered from third parties.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

• 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 (Level 3). 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 a fair value measurement determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurement requires judgment, considering factors specific to the asset or liability.

Derivative Financial Instruments

We record all derivative financial instrument contracts at fair value in our unaudited condensed consolidated balance sheets except for certain contracts that qualify for the 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 derivative instruments that do not qualify as normal purchases and normal sales (whether cash transactions or non-cash mark-to-market adjustments) are reported within cost of sales in our unaudited condensed 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 into such contracts for trading purposes. Changes in assets and liabilities from commodity derivative financial instruments result primarily from changes in market prices, newly originated transactions, and the timing of settlements. We attempt to balance our contractual portfolio in terms of notional amounts and timing of performance and delivery obligations. However, net unbalanced positions can exist or are established based on our assessment of anticipated market movements. Inherent in the resulting contractual portfolio are certain business risks, including commodity price risk and credit risk. Commodity price risk is the risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response to changing market conditions.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 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 master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Income Taxes

We qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reports his 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 reporting purposes 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 on revenues net of cost of sales.

We evaluate uncertain tax positions for recognition and measurement in the unaudited condensed consolidated financial statements. To recognize a tax position, we determine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, 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 of benefit to be recognized in the unaudited condensed consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2018 or March 31, 2018.

Inventories

Our inventories are valued at the lower of cost or net realizable value, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage, and with net realizable value defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments.

Inventories consist of the following at the dates indicated:

	June 30, 2018		March 31, 2018
	(in thousands)
Crude oil	$	77,834	$	77,351
Natural gas liquids:
Propane	48,940		38,910
Butane	46,224		12,613
Other	8,265		6,515
Refined products:
Gasoline	289,021		253,286
Diesel	88,092		113,939
Renewables:
Ethanol	35,227		38,093
Biodiesel	6,883		10,596
Total	$	600,486	$	551,303

Amounts in the table above do not include inventory related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Investments in Unconsolidated Entities

Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. Investments in partnerships and limited liability companies, unless our investment is considered to be minor, and investments in unincorporated joint ventures are also accounted for using the equity method of accounting. Under the equity method, we do not report the individual assets and liabilities of these entities on our unaudited condensed consolidated balance sheets; instead, our ownership interests are reported within investments in unconsolidated entities on our unaudited condensed consolidated balance sheets. Under the equity method, the investment is recorded at acquisition cost, increased by our proportionate share of any earnings and additional capital contributions and decreased by our proportionate share of any losses, distributions paid, and amortization of any excess investment. Excess investment is the amount by which our total investment exceeds our proportionate share of the net assets of the investee.

Our investments in unconsolidated entities consist of the following at the dates indicated:

Entity	Segment	Ownership Interest (1)	Date Acquired or Formed	June 30, 2018		March 31, 2018
				(in thousands)
Water treatment and disposal facility (2)	Water Solutions	50%	August 2015	$	1,995	$	2,094
E Energy Adams, LLC (3)	Refined Products and Renewables	—%	December 2013	—		15,142
Victory Propane, LLC (4)	Corporate and Other	50%	April 2015	—		—
Total				$	1,995	$	17,236

(1) Ownership interest percentages are at June 30, 2018.

(2) This is an investment in an unincorporated joint venture.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

(3) On May 3, 2018, we sold our previously held20%interest in E Energy Adams, LLC for net proceeds of$18.6 million and recorded a gain on disposal of $3.0 million during the three months ended June 30, 2018 within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations.

(4) As our investment is $0 at June 30, 2018, our proportionate share of Victory Propane’s losses have been recorded against the loan receivable we have with Victory Propane. See Note 13 for a further discussion.

Variable Interest Entity

Victory Propane was formed as a joint venture in April 2015 by us and an unrelated third party. The business purpose of Victory Propane is to acquire and/or develop retail propane operations in a defined geographic area. In conjunction with the formation of Victory Propane, we agreed to provide Victory Propane a revolving line of credit of $5.0 million to be used for working capital and/or acquisition funding. Victory Propane began using this revolving line of credit shortly after operations commenced. At June 30, 2018, we provided a majority of Victory Propane’s financing and have concluded that Victory Propane is a variable interest entity because the equity of Victory Propane is not sufficient to fund its activities without additional subordinated financial support. Each joint venture member has an equal ownership interest in Victory Propane and has equal representation on Victory Propane’s board of managers to make all significant decisions relating to the operations of Victory Propane. Therefore, we do not have the power to direct activities that significantly influence the economic performance of Victory Propane and have concluded that we are not the primary beneficiary. Our maximum exposure to loss 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 June 30, 2018.

Other Noncurrent Assets

Other noncurrent assets consist of the following at the dates indicated:

	June 30, 2018		March 31, 2018
	(in thousands)
Loan receivable (1)	$	26,441	$	29,463
Line fill (2)	33,437		34,897
Tank bottoms (3)	44,148		42,044
Minimum shipping fees - pipeline commitments (4)	23,204		88,757
Other	47,908		49,878
Total	$	175,138	$	245,039

(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. At June 30, 2018, line fill consisted of 335,069 barrels of crude oil and 262,000 barrels of propane. At March 31, 2018, line fill consisted of 360,425 barrels of crude oil and 262,000 barrels of propane. Line fill held in pipelines we own is included within property, plant and equipment (see Note 5).

(3) Tank bottoms, which are product volumes required for the operation of storage tanks, are recorded at historical cost. We recover tank bottoms when the storage tanks are removed from service. At June 30, 2018 and March 31, 2018, tank bottoms held in third party terminals consisted of 389,737 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, or deficiency credits, for two contracts with crude oil pipeline operators. This amount can be recovered when volumes shipped exceed the minimum monthly volume commitment (see Note 9). During the three months ended June 30, 2018, we entered into a definitive agreement, as described further in Note 13, in which we agreed to provide the benefit of our deficiency credit under one of these contracts. As a result of providing this benefit to the third party, we wrote off $67.7 million of these deficiency credits to loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statements of operation during the three months ended June 30, 2018. Under the remaining other contract for which we have the future benefit, we currently have 22 months in which to ship the excess volumes.

Amounts in the table above do not include other noncurrent assets related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Accrued Expenses and Other Payables

Accrued expenses and other payables consist of the following at the dates indicated:

	June 30, 2018		March 31, 2018
	(in thousands)
Accrued compensation and benefits	$	16,600	$	18,033
Excise and other tax liabilities	33,982		40,829
Derivative liabilities	66,091		51,039
Accrued interest	32,758		39,947
Product exchange liabilities	13,911		11,842

Deferred gain on sale of general partner interest in TLP (1)	—		30,113
Other	27,275		31,701
Total	$	225,617	$	223,504

(1) See Note 15 for a discussion of the accounting for the deferred gain upon adoption of ASU No. 2014-09 and ASU No. 2017-05.

Amounts in the table above do not include accrued expenses and other payables related to the Retail Propane segment, as these amounts have been classified as liabilities held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Noncontrolling Interests

Noncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. Amounts are adjusted by the noncontrolling interest holder’s proportionate share of the subsidiaries’ earnings or losses each period and any distributions that are paid. Noncontrolling interests are reported as a component of equity, unless the noncontrolling interest is considered redeemable, in which case the noncontrolling interest is recorded between liabilities and equity (mezzanine or temporary equity) in our unaudited condensed consolidated balance sheet. The redeemable noncontrolling interest is adjusted at each balance sheet date to its maximum redemption value if the amount is greater than the carrying value. The redeemable noncontrolling interest is included in liabilities and redeemable noncontrolling interest held for sale in our unaudited condensed consolidated balance sheets (see Note 14). The following table summarizes changes in our redeemable noncontrolling interest (in thousands):

Balance at March 31, 2018	$	9,927
Net loss attributable to redeemable noncontrolling interest	(398		)
Redeemable noncontrolling interest valuation adjustment	3,300
Balance at June 30, 2018	$	12,829

Business Combination Measurement Period

We record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values. Pursuant to GAAP, an entity is allowed 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 acquired and 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 three months endedJune 30, 2018 to our estimates of the acquisition date fair values of assets acquired and liabilities assumed in business combinations that occurred during the fiscal year ended March 31, 2018.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected, which would include accounts receivable. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The ASU is effective for the Partnership beginning April 1, 2020, and requires a modified retrospective method of adoption, although early adoption is permitted. We are currently in the process of assessing the impact of this ASU on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The ASU will replace previous lease accounting guidance in GAAP. The ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The ASU retains a distinction between finance leases and operating leases. The ASU is effective for the Partnership beginning April 1, 2019, and requires a modified retrospective method of adoption. 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 consolidated financial statements.

On April 1, 2018, we adopted ASU No. 2014-09, “Revenue from Contracts with Customers,” using a modified retrospective approach of adoption. ASU No. 2014-09 supersedes previous revenue recognition requirements in Topic 605, “Revenue Recognition,” and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To achieve this core principle, more judgment and estimates are required within the revenue recognition process than required under Topic 605. In addition, ASU No. 2014-09 requires significantly expanded disclosures related to the nature, timing, amount and uncertainty of revenue and cash flows arising from contracts with customers. See Note 15 for a further discussion of the impact of adoption of ASU No. 2014-09 on our unaudited condensed consolidated financial statements and our revenue recognition policies.

On April 1, 2018, we adopted ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” One of the provisions of ASU No. 2016-01 was to supersede the guidance to classify equity securities with readily determinable fair value into different categories (that is, trading or available-for-sale) and require equity securities to be measured at fair value with changes in fair value recognized through net income. As a result of the adoption, we recorded a cumulative effect adjustment of $1.6 million, moving the unrealized loss out of accumulated other comprehensive income and to limited partners’ equity.

Note 3—Loss Per Common Unit

The following table presents our calculation of basic and diluted weighted average common units outstanding for the periods indicated:

	Three Months Ended June 30,

Note 4—Acquisitions

The following summarizes our acquisitions during the three months endedJune 30, 2018:

Water Pipeline Company

On April 24, 2018, we acquired the remaining 18.375% interest in NGL Water Pipelines, LLC operating in the Delaware Basin portion of the Permian Basin in West Texas for total consideration of approximately $4.0 million. The acquisition of the remaining interest was accounted 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 in ownership interest of the subsidiary. As of the date of the transaction, the 18.375% interest had a carrying value of $3.9 million.

Saltwater Water Solutions Facilities

During the three months ended June 30, 2018, we acquired fivesaltwater disposal facilities (including13wells) for total consideration of approximately $98.4 million. The agreements for these acquisitions contemplate post-closing payments for certain working capital items. We are accounting for these transactions as business combinations.

The following table summarizes the preliminary estimates of the fair values as of June 30, 2018, for the assets acquired and liabilities assumed (in thousands):

Property, plant and equipment	$	29,419
Goodwill	51,756
Intangible assets	17,207
Current liabilities	(250		)
Fair value of net assets acquired	$	98,132

As of June 30, 2018, the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of the property, plant and equipment and intangible assets, (ii) calculate any asset retirement obligations and (iii) determine if the leases we assumed are considered to be favorable or unfavorable to market.

Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill represents a premium paid to expand the number of our disposal sites in an oilfield production basin currently serviced by us, thereby enhancing our competitive position as a provider of disposal services in this oilfield production basin. We expect that all of the goodwill will be deductible for federal income tax purposes.

The operations of these water solutions facilities have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the three months endedJune 30, 2018 includes revenues of $1.5 million and operating income of $0.5 million that were generated by the operations of these water solutions facilities. We incurred $0.2 million of transaction costs related to these acquisitions during the three months endedJune 30, 2018. These amounts are recorded within general and administrative expenses in our unaudited condensed consolidated statement of operations.

During the three months endedJune 30, 2018, we also acquired two disposal wells for total consideration of $9.1 million, which we are accounting for as an acquisition of assets.

Freshwater Water Solutions Facilities

During the three months ended June 30, 2018, we acquired fourfreshwater facilities (including16wells) and a right-of-way that can be used for pipelines for total consideration of approximately $14.5 million. The agreement for this acquisition contemplates post-closing payments for certain working capital items. We are accounting for this transaction as a business combination.

The following table summarizes the preliminary estimates of the fair values as of June 30, 2018, for the assets acquired and liabilities assumed (in thousands):

Property, plant and equipment	$	3,052
Goodwill	6,608
Intangible assets	4,840
Fair value of net assets acquired	$	14,500

As of June 30, 2018, the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of the property, plant and equipment and intangible assets, (ii) calculate any asset retirement obligations, (iii) calculate any contingent consideration liabilities and (iv) determine if the leases we assumed are considered to be favorable or unfavorable to market.

Credit Agreement

We are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks. As of June 30, 2018, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.3 billion for cash borrowings and letters of credit (the “Working Capital Facility”), and a revolving credit facility to fund acquisitions and expansion projects, which had a capacity of $465.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). We had letters of credit of $128.4 million on the Working Capital Facility at June 30, 2018.

At June 30, 2018, the borrowings under the Credit Agreement had a weighted average interest rate of 4.79%, calculated as the weighted average LIBOR rate of 2.09% plus a margin of 2.50% for LIBOR borrowings and the prime rate of 5.00% plus a margin of 1.50% on alternate base rate borrowings. At June 30, 2018, the interest rate in effect on letters of credit was 2.50%. Commitment fees were charged at a rate ranging from 0.375% to 0.50% on any unused capacity.

On July 5, 2018, we amended our Credit Agreement. In the amendment, the lenders consented to, subject to the consummation of the Retail Propane disposition, release Retail Propane, LLC and its wholly-owned subsidiaries from its guaranty and other obligations under the loan documents. In return, the Partnership agreed to use the net proceeds from the Retail Propane disposition to pay down existing indebtedness no later than five business days after the consummation of the Retail Propane disposition.

The following table summarizes the debt covenant levels specified in the Credit Agreement as of June 30, 2018:

		Senior Secured	Interest	Total Leverage
Period Beginning	Leverage Ratio (1)	Leverage Ratio (1)	Coverage Ratio (2)	Indebtedness Ratio (1)
June 30, 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 June 30, 2018, our leverage ratio was approximately 4.50 to 1, our senior secured leverage ratio was approximately 0.61 to 1 and our interest coverage ratio was approximately 2.71 to 1.

At June 30, 2018, we were in compliance with the covenants under the Credit Agreement.

Note 9—Commitments and Contingencies

Legal Contingencies

In August 2015, LCT Capital, LLC (“LCT”) filed a lawsuit against NGL Energy Holdings LLC (the “GP”) and the Partnership seeking payment for investment banking services relating to the purchase of TransMontaigne Inc. and related assets in July 2014. After pre-trial rulings, LCT was limited to pursuing claims of (i) quantum meruit (the value of the services rendered by LCT) and (ii) fraudulent misrepresentation against the defendants. Following a jury trial conducted in Delaware state court from July 23, 2018 through August 1, 2018, the jury returned a verdict consisting of an award of $4.0 million for quantum meruit and $29.0 million for fraudulent misrepresentation,subject to statutory interest. The GP and the Partnership contend thatthe jury verdict, at least in respect of fraudulent misrepresentation,is not supportable by eithercontrolling law orthe evidentiary record. Both defendants have a pending motion for judgment as a matter of law on the fraudulent

22

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

misrepresentation claim and plan to file post-verdict motions as appropriatebefore the trial court, and, if need be, will file an appeal to the Delaware Supreme Court. It is our position that the awards, even if they each stand, are not cumulative. Any allocation of the ultimate verdict award between the GP and the Partnership will be made by the Board of Directors once all information is available to it and after the post-trial and anyappellate process has run its course and the verdict is final as a matter of law. Because the Partnership is a named defendant in the suit, and any judgment ultimately awarded would be joint and several with the GP, we have determined that it is probable that the Partnership could be liable for a portion of this judgment. At this time, we believe the amount that could be allocated to the Partnership would not be material as it is estimated to be less than $4.0 million.

We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these other claims, legal actions, and complaints, after consideration of amounts accrued, insurance coverage, and other arrangements, is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our liabilities may change materially as circumstances develop.

Environmental Matters

At June 30, 2018, we have an environmental liability, measured on an undiscounted basis, of $2.6 million, which is recorded within accrued expenses and other payables in our unaudited condensed consolidated balance sheet. Our operations are subject to extensive federal, state, and local environmental laws and regulations. Although we believe our operations are in substantial compliance with applicable environmental laws and regulations, risks of additional costs and liabilities are inherent in our business, and there can be no assurance that we will not incur significant costs. Moreover, it is possible that other developments, such as increasingly stringent environmental laws, regulations and enforcement policies thereunder, and claims for damages to property or persons resulting from the operations, could result in substantial costs. Accordingly, we have adopted policies, practices, and procedures in the areas of pollution control, product safety, occupational health, and the handling, storage, use, and disposal of hazardous materials designed to prevent material environmental or other damage, and to limit the financial liability that could result from such events. However, some risk of environmental or other damage is inherent in our business.

In 2015, as previously disclosed, the U.S. Environmental Protection Agency (“EPA”) informed NGL Crude Logistics, LLC, formerly known as Gavilon, LLC (“Gavilon Energy”), of alleged violations that occurred in 2011 by Gavilon Energy of the Clean Air Act’s renewable fuel standards regulations (prior to its acquisition by 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 District of Iowa against Gavilon Energy and one of its then suppliers, Western Dubuque Biodiesel LLC (“Western Dubuque”). Consistent with the earlier allegations by the EPA, the civil complaint related to transactions between Gavilon Energy and Western Dubuque and the generation of biodiesel renewable identification 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 requiring the 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 to dismiss the amended complaint. On May 24, 2017, the court denied our motion to dismiss. Subsequently, the EPA filed a second amended complaint seeking an order declaring Western Dubuque’s RINs invalid, an order requiring us to retire an equivalent number of valid RINs and an award against us of statutory civil penalties. In May 2018, the parties completed briefing on cross-motions for summary judgment concerning liability issues in the case. On July 3, 2018, the Court denied our summary judgment motion and largely granted the plaintiff’s two summary judgment motions on liability. On July 19, 2018, Gavilon Energy reached an agreement in principle with the EPA regarding the terms of a settlement of the case. Such terms will result in Gavilon Energy incurring an estimated expense of up to $35.0 million over a twelve-month period, which we accrued as of June 30, 2018 and is included within accrued expenses and other payables in our unaudited condensed consolidated balance sheet and other (expense) income, net in our unaudited condensed consolidated statement of operations. The agreement is subject to the parties submitting a definitive consent decree to the Court for its approval. If ultimately approved by the Court, the consent decree will resolve all matters between Gavilon Energy and the EPA in connection with the above-described complaint.

Asset Retirement Obligations

We have contractual and regulatory obligations at certain facilities for which we have to perform remediation, dismantlement, or removal activities when the assets are retired. Our liability for asset retirement obligations is discounted to present value. To calculate the liability, we make estimates and assumptions 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 and the occurrence of future events. The following table summarizes changes in our asset retirement obligation, which is reported within other noncurrent liabilities in our unaudited condensed consolidated balance sheets (in thousands):

Balance at March 31, 2018	$	9,133
Accretion expense	152
Balance at June 30, 2018	$	9,285

In addition to the obligations described above, we may be obligated to remove facilities or perform other remediation upon retirement of certain other assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates are indeterminable. We will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable.

Operating Leases

We 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 June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	97,269
2020	114,665
2021	98,920
2022	73,322
2023	55,750
Thereafter	48,566
Total	$	488,492

Amounts in the table above exclude leases related to the sale of the Retail Propane segment (see Note 14).

Rental expense relating to operating leases was $27.9 million and $30.7 million during the three months endedJune 30, 2018 and 2017, respectively. Amounts do not include rental expense associated with the Retail Propane segment, as these amounts have been classified as part of discontinued operations within our unaudited condensed consolidated statements of operations (see Note 14).

Pipeline Capacity Agreements

We have executed noncancelable agreements with crude oil pipeline operators, which guarantee us minimum monthly shipping capacity on the pipelines. As a result, we are required 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 shipping fees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during each month remaining under the agreement, with some contracts containing 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 shipping delinquency fees. We currently have an asset recorded in other noncurrent assets in our unaudited condensed consolidated balance sheet for minimum shipping fees paid in both the current and previous periods that are expected to be recovered in future periods by exceeding the minimum monthly volumes (see Note 2).

Total	$	81,503

Of the total future minimum throughput payments in the table above, a third party has agreed to assume all rights and privileges and to be fully responsible for any minimum shipping fees due for actual shipments that are less than our allotted capacity related to $21.5 million of the fiscal year 2019 (nine months) amount and $28.8 million of the fiscal year 2020 amount under a definitive agreement we signed during the three months ended June 30, 2018 (see Note 13).

Sales and Purchase Contracts

We have entered into product sales and purchase contracts for which we expect the parties to physically settle and deliver the inventory in future periods.

As these purchase commitments are deliver-or-pay contracts, we have not entered into corresponding long-term sales contracts for volumes we may not receive.

We account for the contracts shown in the tables above using the 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. Contracts in the tables above may have offsetting derivative contracts (described in Note 11) or inventory positions (described in Note 2).

Certain other forward purchase and sale contracts do not qualify for the normal purchase and normal sale election. These contracts are recorded at fair value in our unaudited condensed consolidated balance sheet and are not included in the tables above. These contracts are included in the derivative disclosures in Note 11, and represent $71.3 million of our prepaid expenses and other current assets and $60.3 million of our accrued expenses and other payables at June 30, 2018.

Note 10—Equity

Partnership Equity

The Partnership’s equity consists of a 0.1% general partner interest and a 99.9% limited partner interest, which consists of common units. Our general partner has the right, but not the obligation, to contribute a proportionate amount of capital to us to maintain its 0.1% general partner interest. Our general partner is not required to guarantee or pay any of our debts and obligations.

General Partner Contributions

In connection with the issuance of common units for the vesting of restricted units and the warrants that were exercised for common units during the three months endedJune 30, 2018, we issued 280 notional units to our general partner for less than $0.1 million in order to maintain its 0.1% interest in us.

Equity Issuances

On August 24, 2016, we entered into an equity distribution agreement in connection with an at-the-market program (the “ATM Program”) pursuant to which we may issue and sell up to $200.0 million of common units. We did not issue any common units under the ATM Program during the three months endedJune 30, 2018, and approximately $134.7 million remained available for sale under the ATM Program at June 30, 2018.

We allocated the net proceeds on a relative fair value basis to the Class A Preferred Units, which includes the value of a beneficial conversion feature, and warrants. Accretion for the beneficial conversion feature, recorded as a deemed distribution, was $9.0 million and $3.2 million during the three months endedJune 30, 2018 and 2017, respectively.

The holders of the warrants may exercise one-third of the warrants from and after the first anniversary of the original issue date, another one-third of the warrants from and after the second anniversary and the final one-third of the warrants from and after the third anniversary. The warrants have an exercise price of $0.01 and an eight year term. We repurchased 1,229,575 unvested warrants for a total purchase price of $15.0 million on April 26, 2018. During the three months endedJune 30, 2018, 228,797 warrants were exercised for common units and we received proceeds of less than $0.1 million. As of June 30, 2018, we had 1,458,371 warrants outstanding.

We pay a cumulative, quarterly distribution in arrears at an annual rate of 10.75% on the Class A Preferred Units to the extent declared by the board of directors of our general partner. The following table summarizes distributions declared on our Class A Preferred Units during the last two quarters:

		Amount Paid/Payable to Class A
Date Declared	Date Paid/Payable	Preferred Unitholders
		(in thousands)
April 24, 2018	May 15, 2018	$	6,449
July 24, 2018	August 14, 2018	$	6,449

Class B Preferred Units

On June 13, 2017, we issued 8,400,000 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred 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 the underwriters’ discount of $6.6 million and offering costs of $0.7 million).

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

The current distribution rate for the Class B Preferred Units is 9.0% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). The following table summarizes distributions declared on our Class B Preferred Units during the last two quarters:

			Amount Paid to Class B
Date Declared	Record Date	Date Paid	Preferred Unitholders
			(in thousands)
March 19, 2018	April 2, 2018	April 16, 2018	$	4,725
June 19, 2018	July 2, 2018	July 16, 2018	$	4,725

The distribution amount paid on July 16, 2018 is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at June 30, 2018.

Equity-Based Incentive Compensation

Our general partner has adopted a long-term incentive plan (“LTIP”), which allows for the issuance of equity-based compensation. Our general partner has granted certain restricted units to employees and directors, which vest in tranches, subject to the continued service of the recipients. The awards may 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 the restricted 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 “Service Awards”) and (ii) vest contingent both on the continued service of the recipients through the vesting date and also on the performance of our common units relative to other entities in the Alerian MLP Index (the “Index”) over specified periods of time (the “Performance Awards”).

The following table summarizes the Service Award activity during the three months endedJune 30, 2018:

Unvested Service Award units at March 31, 2018	2,278,875
Units granted	97,992
Units vested and issued	(50,992	)
Units forfeited	(57,250	)
Unvested Service Award units at June 30, 2018	2,268,625

The following table summarizes the scheduled vesting of our unvested Service Award units at June 30, 2018:

Fiscal Year Ending March 31,
2019 (nine months)	933,975
2020	962,225
2021	370,925
2022	1,500
Total	2,268,625

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 period using 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, over the requisite service period 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 of the grant-date value of the award that is vested at that date.

During the three months endedJune 30, 2018 and 2017, we recorded compensation expense related to Service Award units of $2.8 million and $5.3 million, respectively.

Of the restricted units granted and vested during the three months endedJune 30, 2018, 50,992 units were granted as a bonus for performance during the fiscal year ended March 31, 2018. The total amount of these bonus payments were $0.6 million, of which we had accrued $0.6 million as of March 31, 2018.

The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	9,516
2020	6,572
2021	2,072
2022	7
Total	$	18,167

During April 2015, our general partner granted Performance Award units to certain employees. The number of Performance Award units that will vest is contingent on the performance of our common units relative to the performance of the other entities in the Index. Performance will be calculated based on the return on our common units (including changes in the market price of the common units and distributions paid during the performance period) relative to the returns on the common units of the other entities in the Index. As of June 30, 2018, performance will be measured over the following periods:

Vesting Date of Tranche	Performance Period for Tranche
July 1, 2018	July 1, 2015 through June 30, 2018
July 1, 2019	July 1, 2016 through June 30, 2019
July 1, 2020	July 1, 2017 through June 30, 2020

The following table summarizes the Performance Award activity during the three months endedJune 30, 2018:

Unvested Performance Award units at March 31, 2018	917,000
Units forfeited	(36,000	)
Unvested Performance Award units at June 30, 2018	881,000

During the July 1, 2015 through June 30, 2018 performance period, the return on our common units was below the return of the 50th percentile of our peer companies in the Index. As a result, no Performance Award units vested on July 1, 2018 and performance units with the July 1, 2018 vesting date will be forfeited.

The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grant date. 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 earned Performance Awards will terminate, expire and otherwise be forfeited by the participants. During the three months endedJune 30, 2018 and 2017, we recorded compensation expense related to Performance Award units of $1.3 million and $2.1 million, respectively.

The following table summarizes the estimated future expense we expect to record on the unvested Performance Award units at June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	2,609
2020	1,904
2021	383
Total	$	4,896

At June 30, 2018, approximately 1.3 million common units remain available for issuance under the LTIP.

Note 11—Fair Value of Financial Instruments

Our cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other current assets and liabilities (excluding derivative instruments) are carried at amounts which reasonably approximate their fair values due to their short-term nature.

(1) We may purchase or sell a physical commodity where the underlying contract pricing mechanisms are tied to different commodity price indices. These contracts are derivatives we have entered into as an economic hedge against the risk of one commodity price moving relative to another commodity price.

(2) We may have fixed price physical purchases, including inventory, offset by floating price physical sales or floating price physical purchases offset by fixed price physical sales. These contracts are derivatives we have entered into as an economic hedge against the risk of mismatches between fixed and floating price physical obligations.

Amounts in the table above do not include commodity derivative contract positions related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

During the three months endedJune 30, 2018, we recorded a net loss of $52.7 million and during the three months endedJune 30, 2017, we recorded a net gain of $36.5 million from our commodity derivatives to cost of sales in our unaudited condensed consolidated statements of operations.

Credit Risk

We have credit policies that we believe minimize our overall credit risk, including an evaluation of potential counterparties’ financial condition (including credit ratings), collateral requirements under certain circumstances, and the use of industry standard master netting agreements, which allow for offsetting counterparty receivable and payable balances for certain transactions. AtJune 30, 2018, our primary counterparties were retailers, resellers, energy marketers, producers,

31

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

refiners, and dealers. This concentration of counterparties may impact our overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. If a counterparty does not perform on a contract, we may not realize amounts that have been recorded in our unaudited condensed consolidated balance sheets and recognized in our net income.

Interest Rate Risk

Our Revolving Credit Facility is variable-rate debt with interest rates that are generally indexed to bank prime or LIBOR interest rates.AtJune 30, 2018, we had$1.3 billionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.79%.

Fair Value of Fixed-Rate Notes

The following table provides fair value estimates of our fixed-rate notes at June 30, 2018 (in thousands):

Senior Unsecured Notes:

6.125% Notes due 2025	$	369,557

For the Senior Unsecured Notes, the fair value estimates were developed based on publicly traded quotes and would be classified as Level 1 in the fair value hierarchy.

Note 12—Segments

The following table summarizes revenues related to our segments. Revenues for reporting periods beginning after April 1, 2018 are presented under Topic 606 (see Note 15 for a further discussion), while prior periods are not adjusted and continue to be reported under the accounting standard in effect for those periods. Transactions between segments are recorded based on prices negotiated between the segments. The “Corporate and Other” category in the table below includes certain corporate expenses that are not allocated to the reportable segments. The table below does not include amounts related to the Retail Propane segment, as these amounts has been classified within discontinued operations in our unaudited condensed consolidated statements of operations (see Note 14).

Agreement with WPX Energy Marketing, LLC (“WPX”)

During the three months ended June 30, 2018, we entered into a definitive agreement with WPX. Under this agreement, we agreed to provide WPX the benefit of our minimum shipping fees or deficiency credits (fees paid in previous periods that were in excess of the volumes actually shipped) totaling $67.7 million at the time of the transaction (as discussed further in Note 2), which can be utilized for volumes shipped that exceed the minimum monthly volume commitment in subsequent periods. As a result, we wrote-off these minimum shipping fees included within other noncurrent assets in our unaudited condensed consolidated balance sheet (see Note 2) and recorded a loss within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. We also agreed that we would only ship crude oil that we are required to purchase from WPX in utilizing our allotted capacity on these pipelines and they agreed to be fully responsible to us for all deficiency payments (money due when our actual shipments are less than our allotted capacity) for the remaining term of our contract, which totals $50.3 million (as discuss further in Note 9). As consideration for this transaction, we paid WPX a net $35.3 million, which we have recorded as a loss within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. A member of the board of directors of our general partner is also an executive of WPX.

Continuing Involvement

We have commitments to sell up to 104.4 million gallons of propane, valued at $106.5 million (based on the contract price) to Superior and DCC, the purchasers of the Retail Propane segment, through April 2019. During the three months ended June 30, 2018, we received $3.0 million from DCC for propane sold to them during the period.

Note 15—Revenue from Contracts with Customers

Impact of Adoption

We adopted Topic 606 on April 1, 2018, using the modified retrospective method. Revenues for reporting periods beginning after April 1, 2018 are presented under Topic 606, while prior periods are not adjusted and continue to be reported under the accounting standard in effect for those periods. We recorded an increase to the beginning balance of equity as of April 1, 2018, due to the cumulative impact of adopting the standard, as discussed further below.

Based on our evaluation, we anticipate that from time to time, differences in the timing of revenues earned and our right to invoice customers may create contract assets or liabilities. These differences in timing would be the result of contracts that contain minimum volume commitments and tiered pricing provisions, primarily within our Water Solutions segment. In addition, we completed the process of implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under this standard. Furthermore, under this standard we made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that we collect from a customer.

As discussed previously, we deferred a portion of the gain related to the sale of our general partner interest in TransMontaigne Partners L.P., of which the current portion was recorded in accrued expenses and other payables and the long-term portion was recorded in other noncurrent liabilities at March 31, 2018 within our unaudited condensed consolidated balance sheet. As this transaction was accounted for under the real estate guidance in ASC 360-20, Property, Plant and Equipment, wehad been amortizing the gain over the life of the related lease agreements. Upon adoption of ASU No. 2014-09 and ASU No. 2017-05, we determined that this transaction should be accounted for under the guidance of ASC 810-10-40 and utilizing the modified retrospective approach of adoption, the deferred gain as of March 31, 2018 of $139.3 million was recognized in the beginning balance of retained earnings as part of our cumulative effect adjustment at April 1, 2018.

The following tables summarize the impact of adoption on our unaudited condensed consolidated balance sheet and unaudited condensed consolidated statement of operations as of and for the three months ended June 30, 2018:

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

Prior to April 1, 2018, we recognized revenue for services and products when all of the following criteria were met under Topic 605: (i) either services have been rendered or products have been delivered or sold; (ii) persuasive evidence of an arrangement existed; (iii) the price for services was fixed or determinable; and (iv) collectibility was reasonably assured. We recorded deferred revenue when we received amounts from our customers but had not yet met the criteria listed above. We recognized deferred revenue in our consolidated statement of operations when the criteria had been met and all services had been rendered.

Effective April 1, 2018, we recognize revenue for services and products under revenue contracts as our obligations to either perform services or deliver or sell products under the contracts are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation in the contract and is recognized as revenue when, or as, the performance obligation is satisfied. Our revenue contracts in scope under ASU No. 2014-09 primarily have a single performance obligation. The evaluation of when performance obligations have been satisfied and the transaction price that is allocated to our performance obligations requires significant judgment and assumptions, including our evaluation of the timing of when control of the underlying good or service has transferred to our customers and the relative stand-alone selling price of goods and services provided to customers under contracts with multiple performance obligations. Actual results can vary from those judgments and assumptions. We do not have any material contracts with multiple performance obligations or under which we receive material amounts of non-cash consideration at March 31, 2018. Our costs to obtain or fulfill our revenue contracts were not material as of June 30, 2018.

The majority of our revenue agreements are within scope under ASU No. 2014-09 and the remainder of our revenue comes from contracts that are accounted for as derivatives under ASC 815 or that contain nonmonetary exchanges or leases and are in scope under Topics 845 and 840, respectively. See Note 12 for a detail of disaggregated revenue.

Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to allow customers to secure the right to reserve the product or storage capacity to be received or used at a later date, not to receive financing from our customers or to provide customers with financing.

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 to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations.

Crude Oil Logistics Performance Obligations

Within the Crude Oil Logistics segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For sales of commodities, we are obligated to deliver a predetermined amount of product on a month-to-month basis to our customers. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer.

For revenue received from services rendered, we are obligated to provide throughput services to move product via pipeline, truck, railcar, or marine vessel or to provide terminal maintenance services. In either case, the obligation is satisfied over time utilizing the output method based on each volume of product that is moved from the origination point to the final destination or based on the passage of time.

Water Solutions Performance Obligations

Within the Water Solutions segment, revenue is disaggregated into two primary revenue streams that include service revenue and commodity sales revenue. For contracts involving disposal services, we accept wastewater and solids for disposal at our facilities. In cases where we have agreed within a contract or are required by law to remove hydrocarbons from the wastewater, the skim oil will be valued as non-cash consideration. Ordinarily, it is required that the fair value of the skim oil is to be estimated at contract inception; however, due to variability of the form of the non-cash consideration, the amount and dollar value is unknown at the contract inception date. Accordingly, ASC 606-10-32-11 allows us to value the skim oil on the date in which the value becomes known.

The Water Solutions segment has certain disposal contracts that contain the following types of terms or pricing structures that involve significant judge that impacts the determination and timing of revenue.

39

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

• Minimum volume commitments. We receive a shortfall fee if the customer does not deliver a certain amount of volume of wastewater over a specified period of time. At each reporting period, we make a determination as to the likelihood of us earning this fee. We recognize revenue from these contracts when (i) actual volumes are received; and (ii) when the likelihood of a customer exercising its remaining rights to make up the deficient volumes under minimum volume commitments becomes remote (also known as the breakage model).

• Tiered pricing. For contracts with tiered pricing provisions, the period in which the tiers are earned and settled (i.e. the “reset period”) may vary from monthly to over a period of multiple months. If the tiered pricing is based on a month, we allocate the fee to the distinct daily service to which it relates. If the tiered pricing spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise our estimates of variable consideration at each reporting date throughout each reset period.

• Volume discount pricing. Volume discount pricing is a form of variable consideration whereby the customer pays for the volumes delivered on a cumulative basis. Similar to tiered pricing, the period in which the cumulative volumes are earned and settled (i.e. the “reset period”) may vary from daily to over a period of multiple months. If the volume discount is based on a month, we allocate the fee to the distinct daily service to which it relates. If the volume discount period spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise the estimate of variable consideration at each reporting date.

For all of our disposal contracts within the Water Solutions segment, revenue will be recognized over time utilizing the output method based on the volume of wastewater or solids we accept from the customer. For contracts that involve the sale of recovered hydrocarbons and freshwater, we will recognize revenue at a point in time, based on when control of the product is transferred to the customer.

Liquids Performance Obligations

Within the Liquids segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For commodity sales, we are obligated to deliver a specified amount of product over a specified period of time. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer. For revenue received from services rendered, we offer a variety of services which include: (i) storage services where product is commingled; (ii) railcar transportation services; (iii) transloading services; and (iv) logistics services. We are obligated to provide these services over a predetermined period of time. Revenue from service contracts is recognized at a point in time upon the transfer of control each month. All revenue from services is recognized over time utilizing the output method based on volumes stored or moved.

Refined Products and Renewables Performance Obligations

The Refined Products and Renewables segment has one distinct revenue stream, which is revenue from commodity sales. In these agreements, we are obligated to sell a predetermined amount of product over a specified period of time. Revenue for all commodity sales is recognized at a point in time once the customer has lifted the agreed-upon volumes.

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

Remaining Performance Obligations

Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements. The following table summarizes the amount and timing of revenue recognition for such contracts (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	98,428
2020	112,353
2021	110,461
2022	106,386
2023	104,063
Thereafter	322,019
Total	$	853,710

Many agreements are short-term in nature with a contract term of one year or less. For those contracts, we utilized the practical expedient in ASC 606-10-50 that exempts us from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. Additionally, for our product sales contracts, we have elected the practical expedient set out in ASC 606-10-50-14A, which states that we are not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these agreements, each unit of product represents a separate performance obligation and therefore future volumes are wholly unsatisfied and disclosure of transaction price allocated to remaining performance obligations is not required. Under product sales contracts, the variability arises as both volume and pricing (typically index-based) are not known until the product is delivered.

Contract Assets and Liabilities

Amounts owed from our customers under our revenue contracts are typically billed as the service is being provided on a monthly basis and are due within 1-30 days of billing, and are classified as accounts receivable-trade on our unaudited condensed consolidated balance sheets. Under certain of our contracts, we recognize revenues in excess of billings, referred to as contract assets, within prepaid expenses and other current assets in our unaudited condensed consolidated balance sheets. Accounts receivable from contracts with customers are presented within accounts receivable-trade and accounts receivable-affiliates in our unaudited condensed consolidated balance sheets. Our contract asset balances primarily relate to our underground cavern storage contracts with multi-period contracts in which the fee escalates each year and the customer provides upfront payment at the beginning of the contract period. We did not record any contract assets during this period.

Under certain of our contracts we may be entitled to receive payments in advance of satisfying our performance obligations under the contract. We recognize a liability for these payments in excess of revenue recognized, referred to as deferred revenue or contract liabilities, within advance payments received from customers in our unaudited condensed consolidated balance sheets. Our deferred revenue primarily relates to:

• Prepayments. Some revenue contracts contain prepayment provisions within our Liquids business segment. Revenue received related to our underground cavern storage services is received up-front at the beginning of the contract period and deferred until services have been rendered. In some cases, we also received prepayments from customers purchasing commodities, which allows the customer to secure the right to receive their requested volumes in a future period. Revenue from these contracts is initially deferred, thus creating a contract liability.

• Multi-period contract in which fee escalates each subsequent year of the contract. Revenue from these contracts are recognized over time based on a weighted average of what is expected to be received over the life of the contract. As the actual amount billed and received from the customer differs from the amount of revenue recognized, a contract liability is recorded.

• Tiered pricing and volume discount pricing. As described above, we revise our estimates of variable consideration at each reporting date throughout each reset period. As the actual amount billed and received from the customer differs from the amount of revenue recognized, a contract liability is recorded.

41

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

• Capital reimbursements. Certain contracts in our Water Solutions segment require that our customers reimburse us for capital expenditures related to the construction of long-lived assets, such as water gathering pipelines and custody transfer points, utilized to provide services to them under the revenue contracts. Because we consider these amounts as consideration from customers associated with ongoing services to be provided to customers, we defer these upfront payments in deferred revenue and recognize the amounts in revenue over the life of the associated revenue contract as the performance obligations are satisfied under the contract.

Deferred revenue is included in advance payments received from customers on the unaudited condensed consolidated balance sheets as the performance obligations related to these revenues are expected to be satisfied within one year or less.

The following tables summarizes the balances of our contract assets and liabilities at the dates indicated:

Note 16—Subsequent Events

Acquisitions

On July 9, 2018, and in conjunction with the sale of the Retail Propane segment (see Note 1), we acquired the remaining 40% interest in Atlantic Propane, LLC, which was part of our Retail Propane segment, for total consideration of approximately $12.8 million. The acquisition of the remaining interest was accounted 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 in ownership interest of the subsidiary. Atlantic Propane was included in the sale to Superior, as discussed below.

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment to Superior, see Note 1 and Note 14 for a further discussion.

Note 17—Unaudited Condensed Consolidating Guarantor and Non-Guarantor Financial Information

Certain of our wholly owned subsidiaries have, jointly and severally, fully and unconditionally guaranteed the Senior Unsecured Notes (see Note 8). Pursuant to Rule 3-10 of Regulation S-X, we have presented in columnar format the unaudited condensed consolidating financial information for NGL Energy Partners LP (Parent), NGL Energy Finance Corp., the guarantor subsidiaries on a combined basis, and the non-guarantor subsidiaries on a combined basis in the tables below. NGL Energy Partners LP and NGL Energy Finance Corp. are co-issuers of the Senior Unsecured Notes. Since NGL Energy Partners LP received the proceeds from the issuance of the Senior Unsecured Notes, all activity has been reflected in the NGL Energy Partners LP (Parent) column in the tables below.

During the periods presented in the tables below, the status of certain subsidiaries changed, in that they either became guarantors of or ceased to be guarantors of the Senior Unsecured Notes. For purposes of the tables below, when the status of a subsidiary changes, all subsidiary activity is included in either the guarantor subsidiaries column or non-guarantor subsidiaries column based on the status of the subsidiary at the balance sheet date regardless of activity during the year.

There are no significant restrictions that prevent the parent or any of the guarantor subsidiaries from obtaining funds from their respective subsidiaries by dividend or loan. None of the assets of the guarantor subsidiaries (other than the investments in non-guarantor subsidiaries) are restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion of NGL Energy Partners LP’s (“we,” “us,” “our,” or the “Partnership”) financial condition and results of operations as of and for the three months ended June 30, 2018. The discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q (“Quarterly Report”), as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations and the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2018 (“Annual Report”) filed with the Securities and Exchange Commission on May 30, 2018.

Overview

We are a Delaware limited partnership. NGL Energy Holdings LLC serves as our general partner.AtJune 30, 2018, our operations included:

• 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 and pipeline 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 production and for the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, our Water Solutions segment sells the recovered hydrocarbons that result from performing these services and it also sells freshwater to producers for exploration and production activities.

• Our Liquids segment supplies natural gas liquids to retailers, wholesalers, refiners, and petrochemical plants throughout the United States and in Canada using its leased underground storage and fleet of leased railcars, markets regionally through its21owned terminals throughout the United States, and provides terminaling and storage services at its salt dome storage facility joint venture in Utah.

• 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 in21states and the District of Columbia. See Note 14 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a discussion of the accounting for our Retail Propane segment.

• Our Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations, purchases refined petroleum and renewable products primarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedules them for delivery at various locations throughout the country. In addition, in certain storage locations, our Refined Products and Renewables segment may also purchase unfinished gasoline blending components for subsequent blending into finished gasoline to supply our marketing business as well as third parties.

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment to Superior Plus Corp. (“Superior”). See Note 1 and Note 14 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of the transaction.

As discussed in Note 1 to our unaudited condensed consolidated financial statements included in this Quarterly Report, we have classified the assets, liabilities and redeemable noncontrolling interest of the Retail Propane segment as held for sale and the operations as discontinued in our unaudited condensed consolidated financial statements. Accordingly, the results of operations and cash flows related to the entire Retail Propane segment (both the portion sold to DCC LPG in March 2018 and the remaining business sold to Superior) have been classified as discontinued operations for all periods presented (prior periods have been retrospectively adjusted) in the unaudited condensed consolidated statements of operations and unaudited condensed consolidated statements of cash flows.

Items Impacting the Comparability of Our Financial Results

Our current and future results of operations may not be comparable to our historical results of operations for the periods presented due to business combinations, disposals and other transactions. Our results of operations for the three months ended June 30, 2018 are not necessarily indicative of the results of operations to be expected for future periods or for the full fiscal year ending March 31, 2019.

(2) Information is presented as ofJune 30, 2018andJune 30, 2017, respectively.

Crude Oil Sales Revenues.Theincreasewas due primarily toan increasein crude oil prices and sales volumes during thethree months endedJune 30, 2018, compared to thethree months endedJune 30, 2017. The increase in crude oil prices has led to an increase in production volumes for us to market. This segment continued to be impacted by competition and low margins in the majority of the basins across the United States and we continue to market crude oil 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 not profitable.

Crude Oil Transportation and Other Revenues.Theincreasewas due primarily to our Grand Mesa Pipeline whichincreasedrevenues by$3.6 million during the three months endedJune 30, 2018, compared to the three months endedJune 30, 2017. Theincreasewas also due to increased volumes related to production growth in the DJ Basin.During thethree months endedJune 30, 2018, approximately10.0 millionbarrels of crude oil were transported on the Grand Mesa Pipeline, which averaged approximately110,000barrels per day and financial volumes averaged approximately112,000barrels per day (volume amounts are from both internal and external parties).

Cost of Sales-Excluding Impact of Derivatives.Theincreasewas due primarily toan increasein crude oil prices during thethree months endedJune 30, 2018, compared to thethree months endedJune 30, 2017.

Cost of Sales-Derivatives.Our cost of sales during thethree months endedJune 30, 2018wasincreased by $3.8 million of net realized losses on derivatives and $7.4 million of net unrealized losses on derivatives. Our cost of sales during thethree months endedJune 30, 2017 was reduced by $4.4 million of net realized gains on derivatives and $0.7 million of net unrealized gains on derivatives.

Operating and General and Administrative Expenses.Theincreasewas due primarily to our Grand Mesa Pipeline whichincreasedexpenses by$0.8 million during the three months endedJune 30, 2018, compared to the three months endedJune 30, 2017.

Depreciation and Amortization Expense.Thedecrease was due primarily to crude transportation which decreased depreciation and amortization expense by $1.3 million during the three months endedJune 30, 2018, compared to the three months endedJune 30, 2017 as they downsized their fleet of assets.

Loss (Gain) on Disposal or Impairment of Assets, Net. During the three months endedJune 30, 2018, we recorded a net loss of $101.9 million. During the current period, we recorded a loss of $105.0 million on our transaction with a third party in which they agreed to be fully responsible for our future minimum volume commitment in exchange for $67.7 million of deficiency credits on a contract with a crude oil pipeline operator and $35.3 million in cash (see Note 2 and Note 13 to our unaudited condensed consolidated financial statements included in this Quarterly Report). The loss also includes additional costs related to this transaction of $2.0 million. This loss was offset by a gain of $3.1 million due primarily to the sale of a crude oil terminal and the receipt of additional proceeds from the sale of our 50% interest in Glass Mountain Pipeline, LLC (“Glass Mountain”). During the three months endedJune 30, 2017, we recorded a net gain of $3.6 million on the sales of excess pipe and certain other assets.

Operating expenses for wastewater processed ($/barrel)	$	0.38	$	0.42		$	(0.04	)

Disposal Service Fee Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed, partially offset by higher volumes in areas 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 the Permian Basin.

Recovered Hydrocarbon Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed and an increase in crude oil prices.

Other Service Revenues.Other service revenues primarily include solids disposal revenues and water pipeline revenues, both of which increased during the three months endedJune 30, 2018 due to increased volumes.

Cost of Sales-Excluding Impact of Derivatives. The increase was due primarily to an increase in expenses to bring wastewater to certain of our water solutions facilities.

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 the hydrocarbons we expect to recover when processing the wastewater and selling the skim oil.Our cost of sales during thethree months endedJune 30, 2018included$9.1 million of net unrealized losses on derivatives and $4.6 million of net realized losses on derivatives. Our cost of sales during thethree months endedJune 30, 2017included$0.2 million of net realized gains on derivatives.

56

Operating and General and Administrative Expenses.Theincreasewas due primarily tohighercosts of operations of water disposal wells due tohighervolumes processed, partially offset by cost reduction efforts.Due to thehighervolumes processed, our cost per barrel hasdecreased, as shown in the table above.

Depreciation and Amortization Expense.Theincrease was due primarily to acquisitions and developed facilities, partially offset by certain intangible assets being fully amortized during the fiscal year ended March 31, 2018 and three months endedJune 30, 2018.

Loss (Gain) on Disposal or Impairment of Assets, Net. During the three months endedJune 30, 2018, we recorded a net loss of $2.5 million on the disposals of certain assets. During the three months endedJune 30, 2017, we recorded 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, partially offset by a net loss of $0.6 million on the sales of certain assets.

Revaluation of Liabilities.The revaluation of liabilities represents the change in the valuation of our contingent consideration liabilities related to royalty agreements acquired as part of certain business combinations during the fiscal year ended March 31, 2017. Theincreasein the expense during thethree months endedJune 30, 2018was due primarily to higher actual and expected production from new customers, resulting in an increase to the expected future royalty payment.

(1) Revenues include $1.7 million and $1.4 million of intersegment sales during the three months endedJune 30, 2018 and 2017, respectively, that are eliminated in our unaudited condensed consolidated statements of operations.

(2) Information is presented as of June 30, 2018 and June 30, 2017, respectively.

Propane Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales excluding the impact of derivatives were due primarily to higher commodity prices and increased volumes moved by railcars due to third-party pipeline infrastructure issues.

Cost of Sales-Derivatives. Our cost of wholesale propane sales was increased by $0.3 million of net unrealized losses on derivatives and less than $0.1 million of net realized losses on derivatives during the three months endedJune 30, 2018. During the three months endedJune 30, 2017, our cost of wholesale propane sales was increased by $0.3 million of net unrealized losses on derivatives and reduced by $0.1 million of net realized gains on derivatives.

Propane margins increased due to our ability to sell our excess product in certain areas where the product cost was lower.

Butane Sales and Cost of Sales-Excluding Impact of Derivatives. The increases in revenues and cost of sales excluding the impact of derivatives were due primarily to higher commodity prices and increased volumes sold due to our ability to sell into the spot market rather than storing due to favorable pricing.

Cost of Sales-Derivatives. Our cost of butane sales during the three months endedJune 30, 2018 was increased by $2.5 million of net unrealized loss on derivatives, compared to a reduction of $1.7 million of net unrealized gains on derivatives during the three months endedJune 30, 2017. Additionally, our cost of butane sales was increased by $0.1 million of net realized losses on derivatives during the three months endedJune 30, 2018 and reduced by $0.2 million of net realized gains on derivatives during the three months ended June 30, 2017.

Product margins per gallon of butane remained consistent for the current quarter versus the prior year quarter.

Other Products Sales and Cost of Sales-Excluding Impact of Derivatives. The increase in the volume of other products sold was due primarily to increased availability in the natural gasoline and iso-butane markets due to higher than anticipated production.

Cost of Sales-Derivatives. Our cost of sales of other products was reduced by $0.6 million of net realized gains on derivatives and $0.5 million net unrealized gains on derivatives during the three months endedJune 30, 2018. Our cost of sales of other products during the three months endedJune 30, 2017 was reduced by less than $0.1 million of net realized gains on derivatives.

Product margins during the three months endedJune 30, 2018 were higher due primarily to a strong pricing environment and higher than anticipated production.

Other Revenues. This revenue includes storage, terminaling and transportation services income. The decrease was due primarily to lower storage service income.

Operating and General and Administrative Expenses. Expenses for the current quarter were higher due to an increase in employee commissions resulting from increased profit margins.

Depreciation and Amortization Expense. Expenses for the current quarter were consistent with the prior year quarter.

Gain on Disposal or Impairment of Assets, Net. During the three months endedJune 30, 2018, we recorded a net gain of less than $0.1 million related to the retirement of assets.

Refined Products Revenues and Cost of Sales-Excluding Impact of Derivatives.Theincreasesin revenues and cost of sales-excluding impact of derivatives were due toan increasein refined products prices andincreasedvolumes.Theincreasein prices was due primarily to supply and demand for refined fuels at our wholesale locations.Theincreasedvolumes were due primarily to an expansion of our refined products operations and the continued demand for motor fuels.

Refined Products Cost of Sales-Derivatives.The margin for thethree months endedJune 30, 2018 was negatively impacted by alossof$25.1 millionfrom our risk management activities due primarily to increasing future prices.The margin for thethree months endedJune 30, 2017was positively impacted by againof$27.7 millionfrom our risk management activities due primarily to decreasing future prices.

Renewables Revenues and Cost of Sales-Excluding Impact of Derivatives.Thedecreasesin revenues and cost of sales-excluding impact of derivatives were due primarily todecreasedvolumes from the loss of a marketing contract with E Energy Adams, LLC in December 2017, partially offset byan increasein renewables prices due primarily to supply and demand for renewable fuels.

Renewables Cost of Sales-Derivatives.The margin for thethree months endedJune 30, 2018was negatively impacted by alossof$0.8 millionfrom our risk management activities due primarily to increasing future prices.The margin for thethree months endedJune 30, 2017was positively impacted by againof$2.0 millionfrom our risk management activities due primarily to unrealized gains on our open forward positions.

Service Fees and Other Revenues.Theincreasewas due primarily to an early termination settlement for one our sublease agreements during the three months ended June 30, 2018.

Operating and General and Administrative Expenses.Thedecreasewas due primarily to lower environmental expense during thethree months endedJune 30, 2018from an insurance recovery received during the quarter related to a historical environmental indemnification agreement.

Depreciation and Amortization Expense.Depreciation and amortization expense for the current quarter was consistent with the prior year.

Gain on Disposal or Impairment of Assets, Net. During thethree months endedJune 30, 2018, we recordeda gainof$3.0 millionon the sale of our previously held 20% interest in E Energy Adams, LLC (seeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report).During thethree months endedJune 30, 2017, we recorded$7.5 millionof the deferred gain from the sale of the general partner interest in TransMontaigne Partners L.P. in February 2016.SeeNote 15to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of the reasons for the elimination of the deferred gain.

(1) Cost of sales include $0.2 million of intersegment cost of sales during the three months endedJune 30, 2018 that are eliminated in our unaudited condensed consolidated statements of operations.

General and Administrative Expenses. The decrease during the three months endedJune 30, 2018 was due primarily to lower equity-based compensation expense related to our service awards. The expense during the three months endedJune 30, 2018 was $2.8 million, compared to $5.3 million during the three months endedJune 30, 2017. During the three months endedJune 30, 2018, the grant date fair values for service awards granted were lower than the fair values of such awards granted during the prior year. In addition, lower vesting, as well as an overall lower number of service awards outstanding at the end of the three months endedJune 30, 2018 contributed to the lower overall expense. The decrease from equity-based compensation was partially offset by an increase in legal expenses.

Equity in Earnings of Unconsolidated Entities

Thedecreaseof$1.7 millionduring thethree months endedJune 30, 2018was due primarily to decreased earnings related to our investment in Glass Mountain, E Energy Adams, LLC and a water treatment and disposal facility.On December 22, 2017, we sold our previously held 50% interest in Glass Mountain and on May 3, 2018, we sold our previously held 20% interest in E Energy Adams, LLC.SeeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

Interest Expense

Interest expense includes interest expense on our Revolving Credit Facility (as defined herein) and senior notes, amortization of debt issuance costs, letter of credit fees, interest on equipment financing notes, and accretion of interest on non-interest bearing debt obligations. The decrease of $2.8 million during the three months endedJune 30, 2018 was due to the repurchase of all senior secured notes in the prior year. This was partially offset by higher interest expense on our Revolving Credit Facility as our average balance outstanding increased from $0.9 billion for the three months endedJune 30, 2017 to $1.1 billion for the three months endedJune 30, 2018.

Loss on Early Extinguishment of Liabilities, Net

During the three months endedJune 30, 2018, the net losses (inclusive of debt issuance costs written off) relates to the early extinguishment of a portion of the 2023 Notes. During the three months ended June 30, 2017, the net losses (inclusive of debt issuance costs written off) relate to the early extinguishment of a portion of the senior secured notes and the 2019 Notes. SeeNote 8to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

Income Tax Expense

Income tax expense was $0.7 million during the three months endedJune 30, 2018, compared to income tax expense of $0.5 million during the three months endedJune 30, 2017. SeeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

Noncontrolling Interests - Redeemable and Non-redeemable

Noncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. The increase of $0.4 million during the three months endedJune 30, 2018 was due primarily to a loss from operations of the Sawtooth joint venture, as we sold a 28.5% interest in Sawtooth in March 2018.

Non-GAAP Financial Measures

In addition to financial results reported in accordance with accounting principles generally accepted in the United States (“GAAP”), we have provided the non-GAAP financial measures of EBITDA and Adjusted EBITDA. These non-GAAP financial measures are not intended to be a substitute for those reported in accordance with GAAP. These measures may be different from non-GAAP financial measures used by other entities, even when similar terms are 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), and depreciation and amortization expense. We define Adjusted EBITDA as EBITDA excluding net unrealized gains and losses on derivatives, lower of cost or market adjustments, gains and losses on disposal or impairment of assets, gains and losses on early extinguishment of liabilities, equity-based compensation expense, acquisition expense, revaluation of liabilities, certain legal settlements and other. We also includein Adjusted EBITDA certain inventory valuation adjustments related to our Refined Products and Renewables segment, as discussed below.EBITDA and Adjusted EBITDA should not be considered alternatives tonet loss, (loss) income from continuing operations before income taxes, cash flows from operating activities, or any other measure of financial performance calculated in accordance with GAAP, as those items are used to measure operating performance, liquidity or the ability to service debt obligations. We believe that EBITDA provides additional information to investors for evaluating our ability to make quarterly distributions to our unitholders and is presented solely as a supplemental measure. We believe that Adjusted EBITDA provides additional information to investors for evaluating our financial performance without regard to our financing methods, capital structure and historical cost basis.Further, EBITDA and Adjusted EBITDA, as we define 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 between realized and unrealized gains and losses on derivatives.During the period when a derivative contract is open, we record changes in the fair value of the derivative as an unrealized gain or loss.When a derivative contract matures or is settled, we reverse the previously recorded unrealized gain or loss and record a realized gain or loss. We do not draw such a distinction between realized and unrealized gains and losses on derivatives of our Refined Products and Renewables segment.The primary hedging strategy of our Refined Products and Renewables segment is to hedge against the risk of declines in the value of inventory over the course of the contract cycle, and many of the hedges are six months to one year in duration at inception.The “inventory valuation adjustment” row in the reconciliation tablereflects the difference between the market value of the inventory ofourRefined Products and Renewables segment at the balance sheet date and its cost. We include this in Adjusted EBITDA because the unrealized gains and losses associated with derivative contracts associated with the inventory of this segment, which are intended primarily to hedge inventory holding risk and are included in net income, also affect Adjusted EBITDA.

Liquidity, Sources of Capital and Capital Resource Activities

Our principal sources of liquidity and capital are the cash flows from our operations, borrowings under our Revolving Credit Facility and accessing capital markets. See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a detailed description of our long-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 and Refined Products and Renewables businesses. Our greatest working capital borrowing needs generally occur during the period of June through December, when we are building our natural gas liquids inventories in anticipation of the heating season as well as building our gasoline inventory in anticipation of the winter gasoline contango and blending season. Our working capital borrowing needs generally decline during the period of January through March, when the cash flows from our Liquids segment is 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 our partnership 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, less the 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 of our 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 next four quarters.

We believe that our anticipated cash flows from operations and the borrowing capacity under our Revolving Credit Facility are sufficient 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 capital or sell assets. Our ability to raise additional capital, if necessary, depends on various factors and conditions, including market conditions. We cannot give any assurances that we can raise additional capital to meet these needs. Commitments or expenditures, if any, we may make toward any acquisition projects are at our discretion.

67

We have made the strategic decision to completely exit the Retail Propane business and re-deploy proceeds from this sale to repay certain indebtedness and for certain near-term strategic growth opportunities, primarily in the Water Solutions segment. We believe our Water Solutions and Crude Oil Logistics businesses have organic growth opportunities with the activity in our core basins, including the Delaware Basin and DJ Basin in particular. We plan to pursue a strategy of growth through acquisitions as well as undertaking certain capital expansion projects. We expect to consider financing future acquisitions and capital expansion projects through available capacity on our Revolving Credit Facility or other forms of financing.

Other sources of liquidity during the three months endedJune 30, 2018 are discussed below.

Dispositions

On May 3, 2018, we sold our previously held20%interest in E Energy Adams, LLC for net proceeds of$18.6 million.

Subsequent Events

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment for total consideration of$896.5 million in cash after adjusting for estimated working capital, which we used to pay down amounts outstanding under our Revolving Credit Facility.

Long-Term Debt

Credit Agreement

We are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks. As of June 30, 2018, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.3 billion for cash borrowings and letters of credit, (the “Working Capital Facility”) and a revolving credit facility to fund acquisitions and expansion projects, which had a capacity of $465.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). We had letters of credit of $128.4 million on the Working Capital Facility at June 30, 2018.

At June 30, 2018, we were in compliance with the covenants under the Credit Agreement.

Senior Unsecured Notes

The senior unsecured notes include the 2019 Notes, 2021 Notes, 2023 Notes and 2025 Notes.

Repurchases

During the three months endedJune 30, 2018, we repurchased $5.0 million of the 2023 Notes. See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of the repurchases.

Compliance

AtJune 30, 2018, we were in compliance with the covenants under the indentures for all of the senior unsecured notes.

For a further discussion of our Revolving Credit Facility and senior unsecured note repurchases, see Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

(1) Amounts for the three months ended June 30, 2018 and 2017 include $0.4 million and $1.2 million, respectively, related to our Retail Propane segment.

(2) Amounts for the three months ended June 30, 2018 and 2017 include $3.3 million and $2.7 million, respectively, related to our Retail Propane segment.

(3) Amount for the three months ended June 30, 2018 includes $19.1 million related to our Retail Propane segment. There were no amounts related to our Retail Propane segment for the three months ended June 30, 2017.

(4) Amounts for the three months ended June 30, 2018 and 2017 primarily related to contributions made to unconsolidated entities. There were no amounts related to our Retail Propane segment for the three months ended June 30, 2018 or 2017.

Cash Flows

The following table summarizes the sources (uses) of our cash flows from continuing operations for the periods indicated:

	Three Months Ended June 30,
Cash Flows Provided by (Used in)	2018			2017
	(in thousands)
Operating activities, before changes in operating assets and liabilities	$	51,045		$	(33,780	)
Changes in operating assets and liabilities	(124,231		)	24,095
Operating activities-continuing operations	$	(73,186	)	$	(9,685	)
Investing activities-continuing operations	$	(224,512	)	$	(6,934	)
Financing activities-continuing operations	$	289,286		$	25,492

Operating Activities-Continuing Operations. 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, and decreases in natural gas liquids prices typically increase our operating cash flows due to lower cash requirements to fund increases in inventories. In our Liquids business, we

69

typically experience operating losses or lower operating income during our first and second quarters, or the six months ending September 30, as a result of lower volumes of natural gas liquids sales and when we are building our inventory levels for the upcoming heating season. The heating season runs through the six months ending March 31. The seasonal motor fuel blend during the third quarter of our fiscal year impacts the value of our gasoline inventory in our Refined Products and Renewables business and also represents a period when we build inventory into our system. We borrow under our Revolving Credit Facility to supplement our operating cash flows during the periods in which we are building inventory. Our operations, and as a result our cash flows, are also impacted by positive and negative movements in commodity prices, which cause fluctuations in the value of inventory, accounts receivable and payables, due to increases and decreases in revenues and cost of sales. The increase in net cash used in operating activities during the three months endedJune 30, 2018 was due primarily to fluctuations in the value of accounts receivable and payables during the three months endedJune 30, 2018.

Investing Activities-Continuing Operations. Net cash used in investing activities was $224.5 million during the three months endedJune 30, 2018, compared to net cash used in investing activities of $6.9 million during the three months endedJune 30, 2017. The increase in net cash used in investing activities was due primarily to:

• a $91.5 millionincrease in cash paid for acquisitions and investments in unconsolidated entities during the three months endedJune 30, 2018;

• an $84.2 millionincrease in payments to settle derivatives; and

• an increase in capital expenditures from $27.6 million during the three months endedJune 30, 2017 to $72.7 million during the three months endedJune 30, 2018 due primarily to capital expenditures for expansion projects in our Water Solutions segment.

Financing Activities-Continuing Operations. Net cash provided by financing activities was $289.3 million during the three months endedJune 30, 2018, compared to net cash provided by financing activities of $25.5 million during the three months endedJune 30, 2017. The increase in net cash provided by financing activities was due primarily to:

• an increase of $401.5 million in borrowings on our Revolving Credit Facility (net of repayments) during the three months endedJune 30, 2018; and

• a decrease in repurchases of our senior secured and unsecured notes of $69.3 million during the three months endedJune 30, 2018.

These increases were partially offset by a decrease of $203.0 million due to proceeds received from the sale of our preferred units during the three months endedJune 30, 2017.

Distributions Declared

Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash (as defined in our partnership agreement) to unitholders as of the record date. See further discussion of our cash distribution policy in Item 5. Market for Registrant’s Common Equity, Related Unitholder Matters and Issuer Purchases of Equity Securities included in our Annual Report.

On June 19, 2018, the board of directors of our general partner declared a distribution on the Class B Preferred Units for the three months endedJune 30, 2018 of $4.7 million in the aggregate, which was paid to the holders of the Class B Preferred Units on July 16, 2018.

On July 24, 2018, the board of directors of our general partner declared a distribution of $0.39 per common unit to the unitholders of record on August 8, 2018. In addition, the board of directors declared a distribution to the holders of the Class A Preferred Units of $6.4 million in the aggregate. The distributions to both the common unitholders and the holders of the Class A Preferred Units are to be paid on August 14, 2018.

For a further discussion of our distributions, see Note 10 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

(1) The estimated interest payments on our Revolving Credit Facility are based on principal and letters of credit outstanding at June 30, 2018. See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for additional information on our Credit Agreement.

(2) We have executed noncancelable agreements with crude oil operators, which guarantee us minimum monthly shipping capacity on the pipelines. As a result, we are required 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 shipping fees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during each month remaining under the agreement, with some contracts containing 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 shipping delinquency fees. See Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly Report for additional information.

(3) Index prices are based on a forward price curve at June 30, 2018. A theoretical change of $0.10 per gallon of natural gas liquids in the underlying commodity price at June 30, 2018 would result in a change of $80.3 million in the value of our index-price natural gas liquids purchase commitments. A theoretical change of $1.00 per barrel of crude oil in the underlying commodity price at June 30, 2018 would result in a change of $56.9 million in the value of our index-price crude oil purchase commitments. See Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly Report for further detail of the commitments.

(4) Our crude oil index-price purchase commitments exceed our crude oil index-price sales commitments (see Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly 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 commitments are deliver-or-pay contracts, we have not entered into corresponding long-term sales contracts for volumes we may not receive.

Off-Balance Sheet Arrangements

We do not have any off balance sheet arrangements other than the operating leases discussed in Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

The preparation of financial statements and related disclosures in conformity with GAAP requires the selection and application of appropriate accounting principles to the relevant facts and circumstances of our operations and the use of estimates made by management. We have identified certain accounting policies that are most important to the portrayal of our consolidated financial position and results of operations. The application of these accounting policies, which requires subjective or complex judgments regarding estimates and projected outcomes of future events, and changes in these accounting policies, could have a material effect on our consolidated financial statements. There have been no material changes in the critical accounting policies previously disclosed in our Annual Report, with the exception of revenue recognition. For further discussion of the changes to our revenue recognition policy, see Note 15 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

A significant portion of our long-term debt is variable-rate debt. Changes in interest rates impact the interest payments of our variable-rate debt but generally 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 its cash flows.

Our Revolving Credit Facility is variable-rate debt with interest rates that are generally indexed to bank prime or LIBOR interest rates.AtJune 30, 2018, we had$1.3 billionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.79%. A change in interest rates of 0.125% would result in an increase or decrease of our annual interest expense of $1.7 million, based on borrowings outstanding at June 30, 2018.

Commodity Price and Credit Risk

Our operations are subject to certain business risks, including commodity price risk and credit risk. Commodity price risk is the risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response to changing market conditions.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 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 master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.AtJune 30, 2018, our primary counterparties 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 gross profits depend on the differential of sales prices over supply costs. We have no control over market conditions. As a result, our profitability may be impacted by 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, to protect the value of our inventory positions, and to help ensure the availability of product during periods of short supply. We attempt to balance our contractual portfolio by purchasing volumes when we have a matching purchase commitment from our wholesale and retail customers. We may experience net unbalanced positions from time to time. In addition to our ongoing policy to maintain a balanced position, for accounting purposes we are required, on an ongoing basis, to track and report the market value of our derivative portfolio.

Although we use financial derivative instruments to reduce the market price risk associated with forecasted transactions, we do not account for financial derivative transactions as hedges. We record the changes in fair value of these financial derivative transactions within cost of sales in our unaudited condensed consolidated statements of operations. The following table summarizes the hypothetical impact on the June 30, 2018 fair value of our commodity derivatives of an increase of 10% in the value of the underlying commodity (in thousands):

	Increase (Decrease) To Fair Value
Crude oil (Crude Oil Logistics segment)	$	(12,161	)
Propane (Liquids segment)	$	503
Other products (Liquids segment)	$	(2,931	)
Gasoline (Refined Products and Renewables segment)	$	(42,359	)
Diesel (Refined Products and Renewables segment)	$	(11,631	)
Ethanol (Refined Products and Renewables segment)	$	(3,124	)
Biodiesel (Refined Products and Renewables segment)	$	5,409
Canadian dollars (Liquids segment)	$	585

73

Fair Value

We use observable market values for determining the fair value of our derivative instruments. In cases where actively quoted prices are not available, other external sources are used which incorporate information about commodity prices in actively quoted markets, quoted prices in less active markets and other market fundamental analysis.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13(a)-15(e) and 15(d)-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to provide reasonable assurance that information required to be disclosed in our filings and submissions under the Exchange Act is recorded, processed, summarized and reported within the periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management, including the principal executive officer and principal financial officer of our general partner, as appropriate, to allow timely decisions regarding required disclosure.

We completed an evaluation under the supervision and with participation of our management, including the principal executive officer and principal financial officer of our general partner, of the effectiveness of the design and operation of our disclosure controls and procedures at June 30, 2018. Based on this evaluation, the principal executive officer and principal financial officer of our general partner have concluded that as of June 30, 2018, such disclosure controls and procedures were effective to provide the reasonable assurance described above.

There have 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 endedJune 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Organization and Operations

Organization and Operations

NGL Energy Partners LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware limited partnership. NGL Energy Holdings LLC serves as our general partner.AtJune 30, 2018, our operations included:

• 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 and pipeline 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 production and for the disposal of solids such as tank bottoms, drilling fluids and drilling muds and performs truck and frac tank washouts. In addition, our Water Solutions segment sells the recovered hydrocarbons that result from performing these services and it also sells freshwater to producers for exploration and production activities.

• Our Liquids segment supplies natural gas liquids to retailers, wholesalers, refiners, and petrochemical plants throughout the United States and in Canada using its leased underground storage and fleet of leased railcars, markets regionally through its21owned terminals throughout the United States, and provides terminaling and storage services at its salt dome storage facility joint venture in Utah.

• 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 in21states and the District of Columbia. See below for a discussion of the sale of our Retail Propane segment.

• Our Refined Products and Renewables segment conducts gasoline, diesel, ethanol, and biodiesel marketing operations, purchases refined petroleum and renewable products primarily in the Gulf Coast, Southeast and Midwest regions of the United States and schedules them for delivery at various locations throughout the country. In addition, in certain storage locations, our Refined Products and Renewables segment may also purchase unfinished gasoline blending components for subsequent blending into finished gasoline to supply our marketing business as well as third parties.

Recent Developments

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment to Superior Plus Corp. (“Superior”) for total consideration of $896.5 million in cash after adjusting for estimated working capital. Accordingly, upon satisfaction of the significant closing conditions for this transaction during the month of June 2018, the assets, liabilities and redeemable noncontrolling interest of the Retail Propane segment were classified as held for sale in our unaudited condensed consolidated balance sheets. This sale included all three of the retail propane businesses we acquired during the three months ended June 30, 2018 (see Note 4). We retained our 50% ownership interest in Victory Propane, LLC (“Victory Propane”) (see Note 2). This transaction, combined with the sale of a portion of our Retail Propane segment to DCC LPG (“DCC”) on March 30, 2018, represents a strategic shift in our operations and will have a significant effect on our operations and financial results going forward. Accordingly, the results of operations and cash flows related to the entire Retail Propane segment have been classified as discontinued operations for all periods presented and prior periods have been retrospectively adjusted in the unaudited condensed consolidated statements of operations and unaudited condensed consolidated statements of cash flows.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and account balances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, and expenses related to this pipeline in our unaudited condensed consolidated financial statements.

Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim consolidated financial information in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the unaudited condensed consolidated financial statements exclude certain information and notes required by GAAP for complete annual consolidated financial statements. However, we believe that the disclosures made are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements include all adjustments that we consider necessary for a fair presentation of our consolidated financial position, results of operations and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed in this Quarterly Report. The unaudited condensed consolidated balance sheet at March 31, 2018 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2018 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 30, 2018 and adjusted retrospectively for the Retail Propane segment disposition as previously described.

These interim unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report. Due to the seasonal nature of certain of our operations and other factors, the results of operations for interim periods are not necessarily indicative of the results of operations to be expected for future periods or for the full fiscal year ending March 31, 2019.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amount of assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periods presented.

Critical estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the fair value of assets and liabilities acquired in business combinations, the fair value of derivative instruments, the collectibility of accounts receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation, accruals for environmental matters and estimating certain revenues. Although we believe these estimates are reasonable, actual results could differ from those estimates.

Significant Accounting Policies

Our significant accounting policies are consistent with those disclosed in Note 2 of our audited consolidated financial statements included in our Annual Report.

Fair Value Measurements

Fair 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 between market participants at the measurement date. Fair value is based upon assumptions that market participants would use when pricing an asset or liability. We use 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 in inactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, and (iv) inputs that are derived from observable 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 derivative financial instruments utilizing pricing models for similar instruments. Inputs to the pricing models include publicly available prices and forward curves 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 (Level 3). 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 a fair value measurement determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurement requires judgment, considering factors specific to the asset or liability.

Derivative Financial Instruments

We record all derivative financial instrument contracts at fair value in our unaudited condensed consolidated balance sheets except for certain contracts that qualify for the 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 derivative instruments that do not qualify as normal purchases and normal sales (whether cash transactions or non-cash mark-to-market adjustments) are reported within cost of sales in our unaudited condensed 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 into such contracts for trading purposes. Changes in assets and liabilities from commodity derivative financial instruments result primarily from changes in market prices, newly originated transactions, and the timing of settlements. We attempt to balance our contractual portfolio in terms of notional amounts and timing of performance and delivery obligations. However, net unbalanced positions can exist or are established based on our assessment of anticipated market movements. Inherent in the resulting contractual portfolio are certain business risks, including commodity price risk and credit risk. Commodity price risk is the risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response to changing market conditions.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 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 master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Income Taxes

We qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reports his 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 reporting purposes 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 on revenues net of cost of sales.

We evaluate uncertain tax positions for recognition and measurement in the unaudited condensed consolidated financial statements. To recognize a tax position, we determine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, 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 of benefit to be recognized in the unaudited condensed consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2018 or March 31, 2018.

Inventories

Our inventories are valued at the lower of cost or net realizable value, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage, and with net realizable value defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments.

Inventories consist of the following at the dates indicated:

	June 30, 2018		March 31, 2018
	(in thousands)
Crude oil	$	77,834	$	77,351
Natural gas liquids:
Propane	48,940		38,910
Butane	46,224		12,613
Other	8,265		6,515
Refined products:
Gasoline	289,021		253,286
Diesel	88,092		113,939
Renewables:
Ethanol	35,227		38,093
Biodiesel	6,883		10,596
Total	$	600,486	$	551,303

Amounts in the table above do not include inventory related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Investments in Unconsolidated Entities

Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. Investments in partnerships and limited liability companies, unless our investment is considered to be minor, and investments in unincorporated joint ventures are also accounted for using the equity method of accounting. Under the equity method, we do not report the individual assets and liabilities of these entities on our unaudited condensed consolidated balance sheets; instead, our ownership interests are reported within investments in unconsolidated entities on our unaudited condensed consolidated balance sheets. Under the equity method, the investment is recorded at acquisition cost, increased by our proportionate share of any earnings and additional capital contributions and decreased by our proportionate share of any losses, distributions paid, and amortization of any excess investment. Excess investment is the amount by which our total investment exceeds our proportionate share of the net assets of the investee.

Our investments in unconsolidated entities consist of the following at the dates indicated:

Entity	Segment	Ownership Interest (1)	Date Acquired or Formed	June 30, 2018		March 31, 2018
				(in thousands)
Water treatment and disposal facility (2)	Water Solutions	50%	August 2015	$	1,995	$	2,094
E Energy Adams, LLC (3)	Refined Products and Renewables	—%	December 2013	—		15,142
Victory Propane, LLC (4)	Corporate and Other	50%	April 2015	—		—
Total				$	1,995	$	17,236

(1) Ownership interest percentages are at June 30, 2018.

(2) This is an investment in an unincorporated joint venture.

(3) On May 3, 2018, we sold our previously held20%interest in E Energy Adams, LLC for net proceeds of$18.6 million and recorded a gain on disposal of $3.0 million during the three months ended June 30, 2018 within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations.

(4) As our investment is $0 at June 30, 2018, our proportionate share of Victory Propane’s losses have been recorded against the loan receivable we have with Victory Propane. See Note 13 for a further discussion.

Variable Interest Entity

Victory Propane was formed as a joint venture in April 2015 by us and an unrelated third party. The business purpose of Victory Propane is to acquire and/or develop retail propane operations in a defined geographic area. In conjunction with the formation of Victory Propane, we agreed to provide Victory Propane a revolving line of credit of $5.0 million to be used for working capital and/or acquisition funding. Victory Propane began using this revolving line of credit shortly after operations commenced. At June 30, 2018, we provided a majority of Victory Propane’s financing and have concluded that Victory Propane is a variable interest entity because the equity of Victory Propane is not sufficient to fund its activities without additional subordinated financial support. Each joint venture member has an equal ownership interest in Victory Propane and has equal representation on Victory Propane’s board of managers to make all significant decisions relating to the operations of Victory Propane. Therefore, we do not have the power to direct activities that significantly influence the economic performance of Victory Propane and have concluded that we are not the primary beneficiary. Our maximum exposure to loss 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 June 30, 2018.

Other Noncurrent Assets

Other noncurrent assets consist of the following at the dates indicated:

	June 30, 2018		March 31, 2018
	(in thousands)
Loan receivable (1)	$	26,441	$	29,463
Line fill (2)	33,437		34,897
Tank bottoms (3)	44,148		42,044
Minimum shipping fees - pipeline commitments (4)	23,204		88,757
Other	47,908		49,878
Total	$	175,138	$	245,039

(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. At June 30, 2018, line fill consisted of 335,069 barrels of crude oil and 262,000 barrels of propane. At March 31, 2018, line fill consisted of 360,425 barrels of crude oil and 262,000 barrels of propane. Line fill held in pipelines we own is included within property, plant and equipment (see Note 5).

(3) Tank bottoms, which are product volumes required for the operation of storage tanks, are recorded at historical cost. We recover tank bottoms when the storage tanks are removed from service. At June 30, 2018 and March 31, 2018, tank bottoms held in third party terminals consisted of 389,737 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, or deficiency credits, for two contracts with crude oil pipeline operators. This amount can be recovered when volumes shipped exceed the minimum monthly volume commitment (see Note 9). During the three months ended June 30, 2018, we entered into a definitive agreement, as described further in Note 13, in which we agreed to provide the benefit of our deficiency credit under one of these contracts. As a result of providing this benefit to the third party, we wrote off $67.7 million of these deficiency credits to loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statements of operation during the three months ended June 30, 2018. Under the remaining other contract for which we have the future benefit, we currently have 22 months in which to ship the excess volumes.

Amounts in the table above do not include other noncurrent assets related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Accrued Expenses and Other Payables

Amounts in the table above do not include accrued expenses and other payables related to the Retail Propane segment, as these amounts have been classified as liabilities held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

Noncontrolling Interests

Noncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. Amounts are adjusted by the noncontrolling interest holder’s proportionate share of the subsidiaries’ earnings or losses each period and any distributions that are paid. Noncontrolling interests are reported as a component of equity, unless the noncontrolling interest is considered redeemable, in which case the noncontrolling interest is recorded between liabilities and equity (mezzanine or temporary equity) in our unaudited condensed consolidated balance sheet. The redeemable noncontrolling interest is adjusted at each balance sheet date to its maximum redemption value if the amount is greater than the carrying value. The redeemable noncontrolling interest is included in liabilities and redeemable noncontrolling interest held for sale in our unaudited condensed consolidated balance sheets (see Note 14). The following table summarizes changes in our redeemable noncontrolling interest (in thousands):

Balance at March 31, 2018	$	9,927
Net loss attributable to redeemable noncontrolling interest	(398		)
Redeemable noncontrolling interest valuation adjustment	3,300
Balance at June 30, 2018	$	12,829

Business Combination Measurement Period

We record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values. Pursuant to GAAP, an entity is allowed 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 acquired and 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 three months endedJune 30, 2018 to our estimates of the acquisition date fair values of assets acquired and liabilities assumed in business combinations that occurred during the fiscal year ended March 31, 2018.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected, which would include accounts receivable. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The ASU is effective for the Partnership beginning April 1, 2020, and requires a modified retrospective method of adoption, although early adoption is permitted. We are currently in the process of assessing the impact of this ASU on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The ASU will replace previous lease accounting guidance in GAAP. The ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The ASU retains a distinction between finance leases and operating leases. The ASU is effective for the Partnership beginning April 1, 2019, and requires a modified retrospective method of adoption. 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 consolidated financial statements.

On April 1, 2018, we adopted ASU No. 2014-09, “Revenue from Contracts with Customers,” using a modified retrospective approach of adoption. ASU No. 2014-09 supersedes previous revenue recognition requirements in Topic 605, “Revenue Recognition,” and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To achieve this core principle, more judgment and estimates are required within the revenue recognition process than required under Topic 605. In addition, ASU No. 2014-09 requires significantly expanded disclosures related to the nature, timing, amount and uncertainty of revenue and cash flows arising from contracts with customers. See Note 15 for a further discussion of the impact of adoption of ASU No. 2014-09 on our unaudited condensed consolidated financial statements and our revenue recognition policies.

On April 1, 2018, we adopted ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” One of the provisions of ASU No. 2016-01 was to supersede the guidance to classify equity securities with readily determinable fair value into different categories (that is, trading or available-for-sale) and require equity securities to be measured at fair value with changes in fair value recognized through net income. As a result of the adoption, we recorded a cumulative effect adjustment of $1.6 million, moving the unrealized loss out of accumulated other comprehensive income and to limited partners’ equity.

Business Combinations [Abstract]

Acquisitions

Acquisitions

The following summarizes our acquisitions during the three months endedJune 30, 2018:

Water Pipeline Company

On April 24, 2018, we acquired the remaining 18.375% interest in NGL Water Pipelines, LLC operating in the Delaware Basin portion of the Permian Basin in West Texas for total consideration of approximately $4.0 million. The acquisition of the remaining interest was accounted 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 in ownership interest of the subsidiary. As of the date of the transaction, the 18.375% interest had a carrying value of $3.9 million.

Saltwater Water Solutions Facilities

During the three months ended June 30, 2018, we acquired fivesaltwater disposal facilities (including13wells) for total consideration of approximately $98.4 million. The agreements for these acquisitions contemplate post-closing payments for certain working capital items. We are accounting for these transactions as business combinations.

The following table summarizes the preliminary estimates of the fair values as of June 30, 2018, for the assets acquired and liabilities assumed (in thousands):

Property, plant and equipment	$	29,419
Goodwill	51,756
Intangible assets	17,207
Current liabilities	(250		)
Fair value of net assets acquired	$	98,132

As of June 30, 2018, the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of the property, plant and equipment and intangible assets, (ii) calculate any asset retirement obligations and (iii) determine if the leases we assumed are considered to be favorable or unfavorable to market.

Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill represents a premium paid to expand the number of our disposal sites in an oilfield production basin currently serviced by us, thereby enhancing our competitive position as a provider of disposal services in this oilfield production basin. We expect that all of the goodwill will be deductible for federal income tax purposes.

The operations of these water solutions facilities have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the three months endedJune 30, 2018 includes revenues of $1.5 million and operating income of $0.5 million that were generated by the operations of these water solutions facilities. We incurred $0.2 million of transaction costs related to these acquisitions during the three months endedJune 30, 2018. These amounts are recorded within general and administrative expenses in our unaudited condensed consolidated statement of operations.

During the three months endedJune 30, 2018, we also acquired two disposal wells for total consideration of $9.1 million, which we are accounting for as an acquisition of assets.

Freshwater Water Solutions Facilities

During the three months ended June 30, 2018, we acquired fourfreshwater facilities (including16wells) and a right-of-way that can be used for pipelines for total consideration of approximately $14.5 million. The agreement for this acquisition contemplates post-closing payments for certain working capital items. We are accounting for this transaction as a business combination.

The following table summarizes the preliminary estimates of the fair values as of June 30, 2018, for the assets acquired and liabilities assumed (in thousands):

Property, plant and equipment	$	3,052
Goodwill	6,608
Intangible assets	4,840
Fair value of net assets acquired	$	14,500

As of June 30, 2018, the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of the property, plant and equipment and intangible assets, (ii) calculate any asset retirement obligations, (iii) calculate any contingent consideration liabilities and (iv) determine if the leases we assumed are considered to be favorable or unfavorable to market.

Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill represents a premium paid to expand our service offerings in an oilfield production basin currently serviced by us, thereby enhancing our competitive position as a provider of disposal and other services in this oilfield production basin. We expect that all of the goodwill will be deductible for federal income tax purposes.

The operations of these water solutions facilities have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the three months endedJune 30, 2018 includes revenues of $0.5 million and operating income of $0.4 million that were generated by the operations of these water solutions facilities. We incurred $0.2 million of transaction costs related to these acquisitions during the three months endedJune 30, 2018. These amounts are recorded within general and administrative expenses in our unaudited condensed consolidated statement of operations.

Retail Propane Businesses

During the three months endedJune 30, 2018, we acquired three retail propane businesses for total consideration of approximately $19.1 million. We are accounting for these transactions as business combinations. The assets and liabilities are included in current assets and current liabilities held for sale in our unaudited condensed consolidated balance sheet (see Note 14).

Credit Agreement

We are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks. As of June 30, 2018, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.3 billion for cash borrowings and letters of credit (the “Working Capital Facility”), and a revolving credit facility to fund acquisitions and expansion projects, which had a capacity of $465.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). We had letters of credit of $128.4 million on the Working Capital Facility at June 30, 2018.

At June 30, 2018, the borrowings under the Credit Agreement had a weighted average interest rate of 4.79%, calculated as the weighted average LIBOR rate of 2.09% plus a margin of 2.50% for LIBOR borrowings and the prime rate of 5.00% plus a margin of 1.50% on alternate base rate borrowings. At June 30, 2018, the interest rate in effect on letters of credit was 2.50%. Commitment fees were charged at a rate ranging from 0.375% to 0.50% on any unused capacity.

On July 5, 2018, we amended our Credit Agreement. In the amendment, the lenders consented to, subject to the consummation of the Retail Propane disposition, release Retail Propane, LLC and its wholly-owned subsidiaries from its guaranty and other obligations under the loan documents. In return, the Partnership agreed to use the net proceeds from the Retail Propane disposition to pay down existing indebtedness no later than five business days after the consummation of the Retail Propane disposition.

The following table summarizes the debt covenant levels specified in the Credit Agreement as of June 30, 2018:

		Senior Secured	Interest	Total Leverage

(1) Represents the maximum ratio for the period presented.

(2) Represents the minimum ratio for the period presented.

At June 30, 2018, our leverage ratio was approximately 4.50 to 1, our senior secured leverage ratio was approximately 0.61 to 1 and our interest coverage ratio was approximately 2.71 to 1.

At June 30, 2018, we were in compliance with the covenants under the Credit Agreement.

Commitments and Contingencies

Legal Contingencies

In August 2015, LCT Capital, LLC (“LCT”) filed a lawsuit against NGL Energy Holdings LLC (the “GP”) and the Partnership seeking payment for investment banking services relating to the purchase of TransMontaigne Inc. and related assets in July 2014. After pre-trial rulings, LCT was limited to pursuing claims of (i) quantum meruit (the value of the services rendered by LCT) and (ii) fraudulent misrepresentation against the defendants. Following a jury trial conducted in Delaware state court from July 23, 2018 through August 1, 2018, the jury returned a verdict consisting of an award of $4.0 million for quantum meruit and $29.0 million for fraudulent misrepresentation,subject to statutory interest. The GP and the Partnership contend thatthe jury verdict, at least in respect of fraudulent misrepresentation,is not supportable by eithercontrolling law orthe evidentiary record. Both defendants have a pending motion for judgment as a matter of law on the fraudulent misrepresentation claim and plan to file post-verdict motions as appropriatebefore the trial court, and, if need be, will file an appeal to the Delaware Supreme Court. It is our position that the awards, even if they each stand, are not cumulative. Any allocation of the ultimate verdict award between the GP and the Partnership will be made by the Board of Directors once all information is available to it and after the post-trial and anyappellate process has run its course and the verdict is final as a matter of law. Because the Partnership is a named defendant in the suit, and any judgment ultimately awarded would be joint and several with the GP, we have determined that it is probable that the Partnership could be liable for a portion of this judgment. At this time, we believe the amount that could be allocated to the Partnership would not be material as it is estimated to be less than $4.0 million.

We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these other claims, legal actions, and complaints, after consideration of amounts accrued, insurance coverage, and other arrangements, is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our liabilities may change materially as circumstances develop.

Environmental Matters

At June 30, 2018, we have an environmental liability, measured on an undiscounted basis, of $2.6 million, which is recorded within accrued expenses and other payables in our unaudited condensed consolidated balance sheet. Our operations are subject to extensive federal, state, and local environmental laws and regulations. Although we believe our operations are in substantial compliance with applicable environmental laws and regulations, risks of additional costs and liabilities are inherent in our business, and there can be no assurance that we will not incur significant costs. Moreover, it is possible that other developments, such as increasingly stringent environmental laws, regulations and enforcement policies thereunder, and claims for damages to property or persons resulting from the operations, could result in substantial costs. Accordingly, we have adopted policies, practices, and procedures in the areas of pollution control, product safety, occupational health, and the handling, storage, use, and disposal of hazardous materials designed to prevent material environmental or other damage, and to limit the financial liability that could result from such events. However, some risk of environmental or other damage is inherent in our business.

In 2015, as previously disclosed, the U.S. Environmental Protection Agency (“EPA”) informed NGL Crude Logistics, LLC, formerly known as Gavilon, LLC (“Gavilon Energy”), of alleged violations that occurred in 2011 by Gavilon Energy of the Clean Air Act’s renewable fuel standards regulations (prior to its acquisition by 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 District of Iowa against Gavilon Energy and one of its then suppliers, Western Dubuque Biodiesel LLC (“Western Dubuque”). Consistent with the earlier allegations by the EPA, the civil complaint related to transactions between Gavilon Energy and Western Dubuque and the generation of biodiesel renewable identification 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 requiring the 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 to dismiss the amended complaint. On May 24, 2017, the court denied our motion to dismiss. Subsequently, the EPA filed a second amended complaint seeking an order declaring Western Dubuque’s RINs invalid, an order requiring us to retire an equivalent number of valid RINs and an award against us of statutory civil penalties. In May 2018, the parties completed briefing on cross-motions for summary judgment concerning liability issues in the case. On July 3, 2018, the Court denied our summary judgment motion and largely granted the plaintiff’s two summary judgment motions on liability. On July 19, 2018, Gavilon Energy reached an agreement in principle with the EPA regarding the terms of a settlement of the case. Such terms will result in Gavilon Energy incurring an estimated expense of up to $35.0 million over a twelve-month period, which we accrued as of June 30, 2018 and is included within accrued expenses and other payables in our unaudited condensed consolidated balance sheet and other (expense) income, net in our unaudited condensed consolidated statement of operations. The agreement is subject to the parties submitting a definitive consent decree to the Court for its approval. If ultimately approved by the Court, the consent decree will resolve all matters between Gavilon Energy and the EPA in connection with the above-described complaint.

Asset Retirement Obligations

We have contractual and regulatory obligations at certain facilities for which we have to perform remediation, dismantlement, or removal activities when the assets are retired. Our liability for asset retirement obligations is discounted to present value. To calculate the liability, we make estimates and assumptions 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 and the occurrence of future events. The following table summarizes changes in our asset retirement obligation, which is reported within other noncurrent liabilities in our unaudited condensed consolidated balance sheets (in thousands):

Balance at March 31, 2018	$	9,133
Accretion expense	152
Balance at June 30, 2018	$	9,285

In addition to the obligations described above, we may be obligated to remove facilities or perform other remediation upon retirement of certain other assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates are indeterminable. We will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable.

Operating Leases

We 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 June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	97,269
2020	114,665
2021	98,920
2022	73,322
2023	55,750
Thereafter	48,566
Total	$	488,492

Amounts in the table above exclude leases related to the sale of the Retail Propane segment (see Note 14).

Rental expense relating to operating leases was $27.9 million and $30.7 million during the three months endedJune 30, 2018 and 2017, respectively. Amounts do not include rental expense associated with the Retail Propane segment, as these amounts have been classified as part of discontinued operations within our unaudited condensed consolidated statements of operations (see Note 14).

Pipeline Capacity Agreements

We have executed noncancelable agreements with crude oil pipeline operators, which guarantee us minimum monthly shipping capacity on the pipelines. As a result, we are required 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 shipping fees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during each month remaining under the agreement, with some contracts containing 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 shipping delinquency fees. We currently have an asset recorded in other noncurrent assets in our unaudited condensed consolidated balance sheet for minimum shipping fees paid in both the current and previous periods that are expected to be recovered in future periods by exceeding the minimum monthly volumes (see Note 2).

The following table summarizes future minimum throughput payments under these agreements at June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	39,047
2020	42,456
Total	$	81,503

Of the total future minimum throughput payments in the table above, a third party has agreed to assume all rights and privileges and to be fully responsible for any minimum shipping fees due for actual shipments that are less than our allotted capacity related to $21.5 million of the fiscal year 2019 (nine months) amount and $28.8 million of the fiscal year 2020 amount under a definitive agreement we signed during the three months ended June 30, 2018 (see Note 13).

Sales and Purchase Contracts

We have entered into product sales and purchase contracts for which we expect the parties to physically settle and deliver the inventory in future periods.

At June 30, 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 (nine months)	$	52,180	789	$	22,490	28,875
Index-Price Commodity Purchase Commitments:
2019 (nine months)	$	1,199,591	18,097	$	736,389	766,672
2020	707,225		12,148	28,812		36,680

Thereafter	204,050		4,110	—		—
Total	$	3,297,473	56,943	$	765,201	803,352

(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 commitments for crude oil that we purchase and ship on the Grand Mesa Pipeline. As these purchase commitments are deliver-or-pay contracts, we have not entered into corresponding long-term sales contracts for volumes we may not receive.

At June 30, 2018, we had the following commodity sale commitments (in thousands):

	Crude Oil			Natural Gas Liquids
	Value		Volume (in barrels)	Value		Volume (in gallons)
Fixed-Price Commodity Sale Commitments:
2019 (nine months)	$	53,333	794	$	92,537	96,100
2020	—		—	1,040		1,045
2021	—		—	59		60
Total	$	53,333	794	$	93,636	97,205
Index-Price Commodity Sale Commitments:
2019 (nine months)	$	1,060,547	14,873	$	922,685	822,251
2020	103,434		1,570	16,232		16,579
Total	$	1,163,981	16,443	$	938,917	838,830

We account for the contracts shown in the tables above using the 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. Contracts in the tables above may have offsetting derivative contracts (described in Note 11) or inventory positions (described in Note 2).

Certain other forward purchase and sale contracts do not qualify for the normal purchase and normal sale election. These contracts are recorded at fair value in our unaudited condensed consolidated balance sheet and are not included in the tables above. These contracts are included in the derivative disclosures in Note 11, and represent $71.3 million of our prepaid expenses and other current assets and $60.3 million of our accrued expenses and other payables at June 30, 2018.

Equity

3 Months Ended

Jun. 30, 2018

Equity [Abstract]

Equity

Equity

Partnership Equity

The Partnership’s equity consists of a 0.1% general partner interest and a 99.9% limited partner interest, which consists of common units. Our general partner has the right, but not the obligation, to contribute a proportionate amount of capital to us to maintain its 0.1% general partner interest. Our general partner is not required to guarantee or pay any of our debts and obligations.

General Partner Contributions

In connection with the issuance of common units for the vesting of restricted units and the warrants that were exercised for common units during the three months endedJune 30, 2018, we issued 280 notional units to our general partner for less than $0.1 million in order to maintain its 0.1% interest in us.

Equity Issuances

On August 24, 2016, we entered into an equity distribution agreement in connection with an at-the-market program (the “ATM Program”) pursuant to which we may issue and sell up to $200.0 million of common units. We did not issue any common units under the ATM Program during the three months endedJune 30, 2018, and approximately $134.7 million remained available for sale under the ATM Program at June 30, 2018.

Our Distributions

The following table summarizes distributions declared on our common units during the last two quarters:

Date Declared	Record Date	Date Paid/Payable	Amount Per Unit		Amount Paid/Payable to Limited Partners		Amount Paid/Payable to General Partner
					(in thousands)		(in thousands)
April 24, 2018	May 7, 2018	May 15, 2018	$	0.3900	$	47,374	$	82
July 24, 2018	August 8, 2018	August 14, 2018	$	0.3900	$	47,600	$	82

Class A Convertible Preferred Units

On April 21, 2016, we received net proceeds of $235.0 million (net of offering costs of $5.0 million) in connection with the issuance of 19,942,169 Class A Convertible Preferred Units (“Class A Preferred Units”) and 4,375,112 warrants.

We allocated the net proceeds on a relative fair value basis to the Class A Preferred Units, which includes the value of a beneficial conversion feature, and warrants. Accretion for the beneficial conversion feature, recorded as a deemed distribution, was $9.0 million and $3.2 million during the three months endedJune 30, 2018 and 2017, respectively.

The holders of the warrants may exercise one-third of the warrants from and after the first anniversary of the original issue date, another one-third of the warrants from and after the second anniversary and the final one-third of the warrants from and after the third anniversary. The warrants have an exercise price of $0.01 and an eight year term. We repurchased 1,229,575 unvested warrants for a total purchase price of $15.0 million on April 26, 2018. During the three months endedJune 30, 2018, 228,797 warrants were exercised for common units and we received proceeds of less than $0.1 million. As of June 30, 2018, we had 1,458,371 warrants outstanding.

We pay a cumulative, quarterly distribution in arrears at an annual rate of 10.75% on the Class A Preferred Units to the extent declared by the board of directors of our general partner. The following table summarizes distributions declared on our Class A Preferred Units during the last two quarters:

		Amount Paid/Payable to Class A
Date Declared	Date Paid/Payable	Preferred Unitholders
		(in thousands)
April 24, 2018	May 15, 2018	$	6,449
July 24, 2018	August 14, 2018	$	6,449

Class B Preferred Units

On June 13, 2017, we issued 8,400,000 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred 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 the underwriters’ discount of $6.6 million and offering costs of $0.7 million).

The current distribution rate for the Class B Preferred Units is 9.0% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). The following table summarizes distributions declared on our Class B Preferred Units during the last two quarters:

			Amount Paid to Class B
Date Declared	Record Date	Date Paid	Preferred Unitholders
			(in thousands)
March 19, 2018	April 2, 2018	April 16, 2018	$	4,725
June 19, 2018	July 2, 2018	July 16, 2018	$	4,725

The distribution amount paid on July 16, 2018 is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at June 30, 2018.

Equity-Based Incentive Compensation

Our general partner has adopted a long-term incentive plan (“LTIP”), which allows for the issuance of equity-based compensation. Our general partner has granted certain restricted units to employees and directors, which vest in tranches, subject to the continued service of the recipients. The awards may 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 the restricted 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 “Service Awards”) and (ii) vest contingent both on the continued service of the recipients through the vesting date and also on the performance of our common units relative to other entities in the Alerian MLP Index (the “Index”) over specified periods of time (the “Performance Awards”).

The following table summarizes the Service Award activity during the three months endedJune 30, 2018:

Unvested Service Award units at March 31, 2018	2,278,875
Units granted	97,992
Units vested and issued	(50,992	)
Units forfeited	(57,250	)
Unvested Service Award units at June 30, 2018	2,268,625

The following table summarizes the scheduled vesting of our unvested Service Award units at June 30, 2018:

Fiscal Year Ending March 31,
2019 (nine months)	933,975
2020	962,225
2021	370,925
2022	1,500
Total	2,268,625

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 period using 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, over the requisite service period 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 of the grant-date value of the award that is vested at that date.

During the three months endedJune 30, 2018 and 2017, we recorded compensation expense related to Service Award units of $2.8 million and $5.3 million, respectively.

Of the restricted units granted and vested during the three months endedJune 30, 2018, 50,992 units were granted as a bonus for performance during the fiscal year ended March 31, 2018. The total amount of these bonus payments were $0.6 million, of which we had accrued $0.6 million as of March 31, 2018.

The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	9,516
2020	6,572
2021	2,072
2022	7
Total	$	18,167

During April 2015, our general partner granted Performance Award units to certain employees. The number of Performance Award units that will vest is contingent on the performance of our common units relative to the performance of the other entities in the Index. Performance will be calculated based on the return on our common units (including changes in the market price of the common units and distributions paid during the performance period) relative to the returns on the common units of the other entities in the Index. As of June 30, 2018, performance will be measured over the following periods:

Vesting Date of Tranche	Performance Period for Tranche
July 1, 2018	July 1, 2015 through June 30, 2018
July 1, 2019	July 1, 2016 through June 30, 2019
July 1, 2020	July 1, 2017 through June 30, 2020

The following table summarizes the Performance Award activity during the three months endedJune 30, 2018:

Unvested Performance Award units at March 31, 2018	917,000
Units forfeited	(36,000	)
Unvested Performance Award units at June 30, 2018	881,000

During the July 1, 2015 through June 30, 2018 performance period, the return on our common units was below the return of the 50th percentile of our peer companies in the Index. As a result, no Performance Award units vested on July 1, 2018 and performance units with the July 1, 2018 vesting date will be forfeited.

The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grant date. 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 earned Performance Awards will terminate, expire and otherwise be forfeited by the participants. During the three months endedJune 30, 2018 and 2017, we recorded compensation expense related to Performance Award units of $1.3 million and $2.1 million, respectively.

The following table summarizes the estimated future expense we expect to record on the unvested Performance Award units at June 30, 2018 (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	2,609
2020	1,904
2021	383
Total	$	4,896

At June 30, 2018, approximately 1.3 million common units remain available for issuance under the LTIP.

(1) We may purchase or sell a physical commodity where the underlying contract pricing mechanisms are tied to different commodity price indices. These contracts are derivatives we have entered into as an economic hedge against the risk of one commodity price moving relative to another commodity price.

(2) We may have fixed price physical purchases, including inventory, offset by floating price physical sales or floating price physical purchases offset by fixed price physical sales. These contracts are derivatives we have entered into as an economic hedge against the risk of mismatches between fixed and floating price physical obligations.

Amounts in the table above do not include commodity derivative contract positions related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

During the three months endedJune 30, 2018, we recorded a net loss of $52.7 million and during the three months endedJune 30, 2017, we recorded a net gain of $36.5 million from our commodity derivatives to cost of sales in our unaudited condensed consolidated statements of operations.

Credit Risk

We have credit policies that we believe minimize our overall credit risk, including an evaluation of potential counterparties’ financial condition (including credit ratings), collateral requirements under certain circumstances, and the use of industry standard master netting agreements, which allow for offsetting counterparty receivable and payable balances for certain transactions. AtJune 30, 2018, our primary counterparties were retailers, resellers, energy marketers, producers, refiners, and dealers. This concentration of counterparties may impact our overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. If a counterparty does not perform on a contract, we may not realize amounts that have been recorded in our unaudited condensed consolidated balance sheets and recognized in our net income.

Interest Rate Risk

Our Revolving Credit Facility is variable-rate debt with interest rates that are generally indexed to bank prime or LIBOR interest rates.AtJune 30, 2018, we had$1.3 billionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.79%.

Segments

The following table summarizes revenues related to our segments. Revenues for reporting periods beginning after April 1, 2018 are presented under Topic 606 (see Note 15 for a further discussion), while prior periods are not adjusted and continue to be reported under the accounting standard in effect for those periods. Transactions between segments are recorded based on prices negotiated between the segments. The “Corporate and Other” category in the table below includes certain corporate expenses that are not allocated to the reportable segments. The table below does not include amounts related to the Retail Propane segment, as these amounts has been classified within discontinued operations in our unaudited condensed consolidated statements of operations (see Note 14).

Repurchase of Warrants

On April 26, 2018, we repurchased outstanding warrants, as discussed further in Note 10, from funds managed by Oaktree Capital Management, L.P., who are represented on the board of directors of our general partner.

Agreement with WPX Energy Marketing, LLC (“WPX”)

During the three months ended June 30, 2018, we entered into a definitive agreement with WPX. Under this agreement, we agreed to provide WPX the benefit of our minimum shipping fees or deficiency credits (fees paid in previous periods that were in excess of the volumes actually shipped) totaling $67.7 million at the time of the transaction (as discussed further in Note 2), which can be utilized for volumes shipped that exceed the minimum monthly volume commitment in subsequent periods. As a result, we wrote-off these minimum shipping fees included within other noncurrent assets in our unaudited condensed consolidated balance sheet (see Note 2) and recorded a loss within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. We also agreed that we would only ship crude oil that we are required to purchase from WPX in utilizing our allotted capacity on these pipelines and they agreed to be fully responsible to us for all deficiency payments (money due when our actual shipments are less than our allotted capacity) for the remaining term of our contract, which totals $50.3 million (as discuss further in Note 9). As consideration for this transaction, we paid WPX a net $35.3 million, which we have recorded as a loss within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. A member of the board of directors of our general partner is also an executive of WPX.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Impact of Adoption

We adopted Topic 606 on April 1, 2018, using the modified retrospective method. Revenues for reporting periods beginning after April 1, 2018 are presented under Topic 606, while prior periods are not adjusted and continue to be reported under the accounting standard in effect for those periods. We recorded an increase to the beginning balance of equity as of April 1, 2018, due to the cumulative impact of adopting the standard, as discussed further below.

Based on our evaluation, we anticipate that from time to time, differences in the timing of revenues earned and our right to invoice customers may create contract assets or liabilities. These differences in timing would be the result of contracts that contain minimum volume commitments and tiered pricing provisions, primarily within our Water Solutions segment. In addition, we completed the process of implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under this standard. Furthermore, under this standard we made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that we collect from a customer.

As discussed previously, we deferred a portion of the gain related to the sale of our general partner interest in TransMontaigne Partners L.P., of which the current portion was recorded in accrued expenses and other payables and the long-term portion was recorded in other noncurrent liabilities at March 31, 2018 within our unaudited condensed consolidated balance sheet. As this transaction was accounted for under the real estate guidance in ASC 360-20, Property, Plant and Equipment, wehad been amortizing the gain over the life of the related lease agreements. Upon adoption of ASU No. 2014-09 and ASU No. 2017-05, we determined that this transaction should be accounted for under the guidance of ASC 810-10-40 and utilizing the modified retrospective approach of adoption, the deferred gain as of March 31, 2018 of $139.3 million was recognized in the beginning balance of retained earnings as part of our cumulative effect adjustment at April 1, 2018.

The following tables summarize the impact of adoption on our unaudited condensed consolidated balance sheet and unaudited condensed consolidated statement of operations as of and for the three months ended June 30, 2018:

Net loss	$	(169,289	)	$	(161,761	)	$	(7,528	)

Prior to April 1, 2018, we recognized revenue for services and products when all of the following criteria were met under Topic 605: (i) either services have been rendered or products have been delivered or sold; (ii) persuasive evidence of an arrangement existed; (iii) the price for services was fixed or determinable; and (iv) collectibility was reasonably assured. We recorded deferred revenue when we received amounts from our customers but had not yet met the criteria listed above. We recognized deferred revenue in our consolidated statement of operations when the criteria had been met and all services had been rendered.

Effective April 1, 2018, we recognize revenue for services and products under revenue contracts as our obligations to either perform services or deliver or sell products under the contracts are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation in the contract and is recognized as revenue when, or as, the performance obligation is satisfied. Our revenue contracts in scope under ASU No. 2014-09 primarily have a single performance obligation. The evaluation of when performance obligations have been satisfied and the transaction price that is allocated to our performance obligations requires significant judgment and assumptions, including our evaluation of the timing of when control of the underlying good or service has transferred to our customers and the relative stand-alone selling price of goods and services provided to customers under contracts with multiple performance obligations. Actual results can vary from those judgments and assumptions. We do not have any material contracts with multiple performance obligations or under which we receive material amounts of non-cash consideration at March 31, 2018. Our costs to obtain or fulfill our revenue contracts were not material as of June 30, 2018.

The majority of our revenue agreements are within scope under ASU No. 2014-09 and the remainder of our revenue comes from contracts that are accounted for as derivatives under ASC 815 or that contain nonmonetary exchanges or leases and are in scope under Topics 845 and 840, respectively. See Note 12 for a detail of disaggregated revenue.

Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to allow customers to secure the right to reserve the product or storage capacity to be received or used at a later date, not to receive financing from our customers or to provide customers with financing.

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 to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations.

Crude Oil Logistics Performance Obligations

Within the Crude Oil Logistics segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For sales of commodities, we are obligated to deliver a predetermined amount of product on a month-to-month basis to our customers. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer.

For revenue received from services rendered, we are obligated to provide throughput services to move product via pipeline, truck, railcar, or marine vessel or to provide terminal maintenance services. In either case, the obligation is satisfied over time utilizing the output method based on each volume of product that is moved from the origination point to the final destination or based on the passage of time.

Water Solutions Performance Obligations

Within the Water Solutions segment, revenue is disaggregated into two primary revenue streams that include service revenue and commodity sales revenue. For contracts involving disposal services, we accept wastewater and solids for disposal at our facilities. In cases where we have agreed within a contract or are required by law to remove hydrocarbons from the wastewater, the skim oil will be valued as non-cash consideration. Ordinarily, it is required that the fair value of the skim oil is to be estimated at contract inception; however, due to variability of the form of the non-cash consideration, the amount and dollar value is unknown at the contract inception date. Accordingly, ASC 606-10-32-11 allows us to value the skim oil on the date in which the value becomes known.

The Water Solutions segment has certain disposal contracts that contain the following types of terms or pricing structures that involve significant judge that impacts the determination and timing of revenue.

• Minimum volume commitments. We receive a shortfall fee if the customer does not deliver a certain amount of volume of wastewater over a specified period of time. At each reporting period, we make a determination as to the likelihood of us earning this fee. We recognize revenue from these contracts when (i) actual volumes are received; and (ii) when the likelihood of a customer exercising its remaining rights to make up the deficient volumes under minimum volume commitments becomes remote (also known as the breakage model).

• Tiered pricing. For contracts with tiered pricing provisions, the period in which the tiers are earned and settled (i.e. the “reset period”) may vary from monthly to over a period of multiple months. If the tiered pricing is based on a month, we allocate the fee to the distinct daily service to which it relates. If the tiered pricing spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise our estimates of variable consideration at each reporting date throughout each reset period.

• Volume discount pricing. Volume discount pricing is a form of variable consideration whereby the customer pays for the volumes delivered on a cumulative basis. Similar to tiered pricing, the period in which the cumulative volumes are earned and settled (i.e. the “reset period”) may vary from daily to over a period of multiple months. If the volume discount is based on a month, we allocate the fee to the distinct daily service to which it relates. If the volume discount period spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise the estimate of variable consideration at each reporting date.

For all of our disposal contracts within the Water Solutions segment, revenue will be recognized over time utilizing the output method based on the volume of wastewater or solids we accept from the customer. For contracts that involve the sale of recovered hydrocarbons and freshwater, we will recognize revenue at a point in time, based on when control of the product is transferred to the customer.

Liquids Performance Obligations

Within the Liquids segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For commodity sales, we are obligated to deliver a specified amount of product over a specified period of time. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer. For revenue received from services rendered, we offer a variety of services which include: (i) storage services where product is commingled; (ii) railcar transportation services; (iii) transloading services; and (iv) logistics services. We are obligated to provide these services over a predetermined period of time. Revenue from service contracts is recognized at a point in time upon the transfer of control each month. All revenue from services is recognized over time utilizing the output method based on volumes stored or moved.

Refined Products and Renewables Performance Obligations

The Refined Products and Renewables segment has one distinct revenue stream, which is revenue from commodity sales. In these agreements, we are obligated to sell a predetermined amount of product over a specified period of time. Revenue for all commodity sales is recognized at a point in time once the customer has lifted the agreed-upon volumes.

Remaining Performance Obligations

Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements. The following table summarizes the amount and timing of revenue recognition for such contracts (in thousands):

Fiscal Year Ending March 31,
2019 (nine months)	$	98,428
2020	112,353
2021	110,461
2022	106,386
2023	104,063
Thereafter	322,019
Total	$	853,710

Many agreements are short-term in nature with a contract term of one year or less. For those contracts, we utilized the practical expedient in ASC 606-10-50 that exempts us from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. Additionally, for our product sales contracts, we have elected the practical expedient set out in ASC 606-10-50-14A, which states that we are not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these agreements, each unit of product represents a separate performance obligation and therefore future volumes are wholly unsatisfied and disclosure of transaction price allocated to remaining performance obligations is not required. Under product sales contracts, the variability arises as both volume and pricing (typically index-based) are not known until the product is delivered.

Contract Assets and Liabilities

Amounts owed from our customers under our revenue contracts are typically billed as the service is being provided on a monthly basis and are due within 1-30 days of billing, and are classified as accounts receivable-trade on our unaudited condensed consolidated balance sheets. Under certain of our contracts, we recognize revenues in excess of billings, referred to as contract assets, within prepaid expenses and other current assets in our unaudited condensed consolidated balance sheets. Accounts receivable from contracts with customers are presented within accounts receivable-trade and accounts receivable-affiliates in our unaudited condensed consolidated balance sheets. Our contract asset balances primarily relate to our underground cavern storage contracts with multi-period contracts in which the fee escalates each year and the customer provides upfront payment at the beginning of the contract period. We did not record any contract assets during this period.

Under certain of our contracts we may be entitled to receive payments in advance of satisfying our performance obligations under the contract. We recognize a liability for these payments in excess of revenue recognized, referred to as deferred revenue or contract liabilities, within advance payments received from customers in our unaudited condensed consolidated balance sheets. Our deferred revenue primarily relates to:

• Prepayments. Some revenue contracts contain prepayment provisions within our Liquids business segment. Revenue received related to our underground cavern storage services is received up-front at the beginning of the contract period and deferred until services have been rendered. In some cases, we also received prepayments from customers purchasing commodities, which allows the customer to secure the right to receive their requested volumes in a future period. Revenue from these contracts is initially deferred, thus creating a contract liability.

• Multi-period contract in which fee escalates each subsequent year of the contract. Revenue from these contracts are recognized over time based on a weighted average of what is expected to be received over the life of the contract. As the actual amount billed and received from the customer differs from the amount of revenue recognized, a contract liability is recorded.

• Tiered pricing and volume discount pricing. As described above, we revise our estimates of variable consideration at each reporting date throughout each reset period. As the actual amount billed and received from the customer differs from the amount of revenue recognized, a contract liability is recorded.

• Capital reimbursements. Certain contracts in our Water Solutions segment require that our customers reimburse us for capital expenditures related to the construction of long-lived assets, such as water gathering pipelines and custody transfer points, utilized to provide services to them under the revenue contracts. Because we consider these amounts as consideration from customers associated with ongoing services to be provided to customers, we defer these upfront payments in deferred revenue and recognize the amounts in revenue over the life of the associated revenue contract as the performance obligations are satisfied under the contract.

Deferred revenue is included in advance payments received from customers on the unaudited condensed consolidated balance sheets as the performance obligations related to these revenues are expected to be satisfied within one year or less.

The following tables summarizes the balances of our contract assets and liabilities at the dates indicated:

Acquisitions

On July 9, 2018, and in conjunction with the sale of the Retail Propane segment (see Note 1), we acquired the remaining 40% interest in Atlantic Propane, LLC, which was part of our Retail Propane segment, for total consideration of approximately $12.8 million. The acquisition of the remaining interest was accounted 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 in ownership interest of the subsidiary. Atlantic Propane was included in the sale to Superior, as discussed below.

On July 10, 2018, we completed the sale of virtually all of our Retail Propane segment to Superior, see Note 1 and Note 14 for a further discussion.

Unaudited Condensed Consolidating Guarantor and Non-Guarantor Financial Information [Abstract]

Unaudited Condensed Consolidating Guarantor and Non-Guarantor Financial Information

Unaudited Condensed Consolidating Guarantor and Non-Guarantor Financial Information

Certain of our wholly owned subsidiaries have, jointly and severally, fully and unconditionally guaranteed the Senior Unsecured Notes (see Note 8). Pursuant to Rule 3-10 of Regulation S-X, we have presented in columnar format the unaudited condensed consolidating financial information for NGL Energy Partners LP (Parent), NGL Energy Finance Corp., the guarantor subsidiaries on a combined basis, and the non-guarantor subsidiaries on a combined basis in the tables below. NGL Energy Partners LP and NGL Energy Finance Corp. are co-issuers of the Senior Unsecured Notes. Since NGL Energy Partners LP received the proceeds from the issuance of the Senior Unsecured Notes, all activity has been reflected in the NGL Energy Partners LP (Parent) column in the tables below.

During the periods presented in the tables below, the status of certain subsidiaries changed, in that they either became guarantors of or ceased to be guarantors of the Senior Unsecured Notes. For purposes of the tables below, when the status of a subsidiary changes, all subsidiary activity is included in either the guarantor subsidiaries column or non-guarantor subsidiaries column based on the status of the subsidiary at the balance sheet date regardless of activity during the year.

There are no significant restrictions that prevent the parent or any of the guarantor subsidiaries from obtaining funds from their respective subsidiaries by dividend or loan. None of the assets of the guarantor subsidiaries (other than the investments in non-guarantor subsidiaries) are restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended.

For purposes of the tables below, (i) the unaudited condensed consolidating financial information is presented on a legal entity basis, (ii) investments in consolidated subsidiaries are accounted for as equity method investments, and (iii) contributions, distributions, and advances to (from) consolidated entities are reported on a net basis within net changes in advances with consolidated entities in the unaudited condensed consolidating statement of cash flow tables below.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and account balances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, and expenses related to this pipeline in our unaudited condensed consolidated financial statements.

Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim consolidated financial information in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the unaudited condensed consolidated financial statements exclude certain information and notes required by GAAP for complete annual consolidated financial statements. However, we believe that the disclosures made are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements include all adjustments that we consider necessary for a fair presentation of our consolidated financial position, results of operations and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed in this Quarterly Report. The unaudited condensed consolidated balance sheet at March 31, 2018 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2018 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 30, 2018 and adjusted retrospectively for the Retail Propane segment disposition as previously described.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amount of assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periods presented.

Critical estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the fair value of assets and liabilities acquired in business combinations, the fair value of derivative instruments, the collectibility of accounts receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation, accruals for environmental matters and estimating certain revenues. Although we believe these estimates are reasonable, actual results could differ from those estimates.

Fair Value Measurements

Fair Value Measurements

Fair 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 between market participants at the measurement date. Fair value is based upon assumptions that market participants would use when pricing an asset or liability. We use 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 in inactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, and (iv) inputs that are derived from observable 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 derivative financial instruments utilizing pricing models for similar instruments. Inputs to the pricing models include publicly available prices and forward curves 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 (Level 3). 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 a fair value measurement determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurement requires judgment, considering factors specific to the asset or liability.

Derivative Financial Instruments

Derivative Financial Instruments

We record all derivative financial instrument contracts at fair value in our unaudited condensed consolidated balance sheets except for certain contracts that qualify for the 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 derivative instruments that do not qualify as normal purchases and normal sales (whether cash transactions or non-cash mark-to-market adjustments) are reported within cost of sales in our unaudited condensed 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 into such contracts for trading purposes. Changes in assets and liabilities from commodity derivative financial instruments result primarily from changes in market prices, newly originated transactions, and the timing of settlements. We attempt to balance our contractual portfolio in terms of notional amounts and timing of performance and delivery obligations. However, net unbalanced positions can exist or are established based on our assessment of anticipated market movements. Inherent in the resulting contractual portfolio are certain business risks, including commodity price risk and credit risk. Commodity price risk is the risk that the market value of crude oil, natural gas liquids, or refined and renewables products will change, either favorably or unfavorably, in response to changing market conditions.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 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 master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Income Taxes

Income Taxes

We qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reports his 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 reporting purposes 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 on revenues net of cost of sales.

We evaluate uncertain tax positions for recognition and measurement in the unaudited condensed consolidated financial statements. To recognize a tax position, we determine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, 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 of benefit to be recognized in the unaudited condensed consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2018 or March 31, 2018.

Inventories

Inventories

Our inventories are valued at the lower of cost or net realizable value, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage, and with net realizable value defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments.

Investments in Unconsolidated Entities

Investments in Unconsolidated Entities

Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. Investments in partnerships and limited liability companies, unless our investment is considered to be minor, and investments in unincorporated joint ventures are also accounted for using the equity method of accounting. Under the equity method, we do not report the individual assets and liabilities of these entities on our unaudited condensed consolidated balance sheets; instead, our ownership interests are reported within investments in unconsolidated entities on our unaudited condensed consolidated balance sheets. Under the equity method, the investment is recorded at acquisition cost, increased by our proportionate share of any earnings and additional capital contributions and decreased by our proportionate share of any losses, distributions paid, and amortization of any excess investment. Excess investment is the amount by which our total investment exceeds our proportionate share of the net assets of the investee.

Variable Interest Entity

Variable Interest Entity

Victory Propane was formed as a joint venture in April 2015 by us and an unrelated third party. The business purpose of Victory Propane is to acquire and/or develop retail propane operations in a defined geographic area. In conjunction with the formation of Victory Propane, we agreed to provide Victory Propane a revolving line of credit of $5.0 million to be used for working capital and/or acquisition funding. Victory Propane began using this revolving line of credit shortly after operations commenced. At June 30, 2018, we provided a majority of Victory Propane’s financing and have concluded that Victory Propane is a variable interest entity because the equity of Victory Propane is not sufficient to fund its activities without additional subordinated financial support. Each joint venture member has an equal ownership interest in Victory Propane and has equal representation on Victory Propane’s board of managers to make all significant decisions relating to the operations of Victory Propane. Therefore, we do not have the power to direct activities that significantly influence the economic performance of Victory Propane and have concluded that we are not the primary beneficiary. Our maximum exposure to loss 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 June 30, 2018.

Noncontrolling Interests

Noncontrolling Interests

Noncontrolling interests represent the portion of certain consolidated subsidiaries that are owned by third parties. Amounts are adjusted by the noncontrolling interest holder’s proportionate share of the subsidiaries’ earnings or losses each period and any distributions that are paid. Noncontrolling interests are reported as a component of equity, unless the noncontrolling interest is considered redeemable, in which case the noncontrolling interest is recorded between liabilities and equity (mezzanine or temporary equity) in our unaudited condensed consolidated balance sheet. The redeemable noncontrolling interest is adjusted at each balance sheet date to its maximum redemption value if the amount is greater than the carrying value. The redeemable noncontrolling interest is included in liabilities and redeemable noncontrolling interest held for sale in our unaudited condensed consolidated balance sheets (see Note 14).

Business Combination Measurement Period

Business Combination Measurement Period

We record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values. Pursuant to GAAP, an entity is allowed 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 acquired and 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 three months endedJune 30, 2018 to our estimates of the acquisition date fair values of assets acquired and liabilities assumed in business combinations that occurred during the fiscal year ended March 31, 2018.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected, which would include accounts receivable. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The ASU is effective for the Partnership beginning April 1, 2020, and requires a modified retrospective method of adoption, although early adoption is permitted. We are currently in the process of assessing the impact of this ASU on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The ASU will replace previous lease accounting guidance in GAAP. The ASU requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The ASU retains a distinction between finance leases and operating leases. The ASU is effective for the Partnership beginning April 1, 2019, and requires a modified retrospective method of adoption. 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 consolidated financial statements.

On April 1, 2018, we adopted ASU No. 2014-09, “Revenue from Contracts with Customers,” using a modified retrospective approach of adoption. ASU No. 2014-09 supersedes previous revenue recognition requirements in Topic 605, “Revenue Recognition,” and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To achieve this core principle, more judgment and estimates are required within the revenue recognition process than required under Topic 605. In addition, ASU No. 2014-09 requires significantly expanded disclosures related to the nature, timing, amount and uncertainty of revenue and cash flows arising from contracts with customers. See Note 15 for a further discussion of the impact of adoption of ASU No. 2014-09 on our unaudited condensed consolidated financial statements and our revenue recognition policies.

On April 1, 2018, we adopted ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” One of the provisions of ASU No. 2016-01 was to supersede the guidance to classify equity securities with readily determinable fair value into different categories (that is, trading or available-for-sale) and require equity securities to be measured at fair value with changes in fair value recognized through net income. As a result of the adoption, we recorded a cumulative effect adjustment of $1.6 million, moving the unrealized loss out of accumulated other comprehensive income and to limited partners’ equity.

Equity (Policies)

3 Months Ended

Jun. 30, 2018

Equity [Abstract]

Service Awards

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 period using 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, over the requisite service period 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 of the grant-date value of the award that is vested at that date.

Performance Awards

The fair value of the Performance Awards is estimated using a Monte Carlo simulation at the grant date. 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 earned Performance Awards will terminate, expire and otherwise be forfeited by the participants.

Revenue from Contracts with Customers (Policies)

3 Months Ended

Jun. 30, 2018

Revenue from Contract with Customer [Abstract]

Revenue, Transaction Price Measurement, Tax Exclusion [Policy Text Block]

Furthermore, under this standard we made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that we collect from a customer.

Revenue Recognition

Prior to April 1, 2018, we recognized revenue for services and products when all of the following criteria were met under Topic 605: (i) either services have been rendered or products have been delivered or sold; (ii) persuasive evidence of an arrangement existed; (iii) the price for services was fixed or determinable; and (iv) collectibility was reasonably assured. We recorded deferred revenue when we received amounts from our customers but had not yet met the criteria listed above. We recognized deferred revenue in our consolidated statement of operations when the criteria had been met and all services had been rendered.

Effective April 1, 2018, we recognize revenue for services and products under revenue contracts as our obligations to either perform services or deliver or sell products under the contracts are satisfied. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation in the contract and is recognized as revenue when, or as, the performance obligation is satisfied. Our revenue contracts in scope under ASU No. 2014-09 primarily have a single performance obligation. The evaluation of when performance obligations have been satisfied and the transaction price that is allocated to our performance obligations requires significant judgment and assumptions, including our evaluation of the timing of when control of the underlying good or service has transferred to our customers and the relative stand-alone selling price of goods and services provided to customers under contracts with multiple performance obligations. Actual results can vary from those judgments and assumptions. We do not have any material contracts with multiple performance obligations or under which we receive material amounts of non-cash consideration at March 31, 2018. Our costs to obtain or fulfill our revenue contracts were not material as of June 30, 2018.

The majority of our revenue agreements are within scope under ASU No. 2014-09 and the remainder of our revenue comes from contracts that are accounted for as derivatives under ASC 815 or that contain nonmonetary exchanges or leases and are in scope under Topics 845 and 840, respectively. See Note 12 for a detail of disaggregated revenue.

Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to allow customers to secure the right to reserve the product or storage capacity to be received or used at a later date, not to receive financing from our customers or to provide customers with financing.

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 to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations.

Crude Oil Logistics Performance Obligations

Within the Crude Oil Logistics segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For sales of commodities, we are obligated to deliver a predetermined amount of product on a month-to-month basis to our customers. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer.

For revenue received from services rendered, we are obligated to provide throughput services to move product via pipeline, truck, railcar, or marine vessel or to provide terminal maintenance services. In either case, the obligation is satisfied over time utilizing the output method based on each volume of product that is moved from the origination point to the final destination or based on the passage of time.

Water Solutions Performance Obligations

Within the Water Solutions segment, revenue is disaggregated into two primary revenue streams that include service revenue and commodity sales revenue. For contracts involving disposal services, we accept wastewater and solids for disposal at our facilities. In cases where we have agreed within a contract or are required by law to remove hydrocarbons from the wastewater, the skim oil will be valued as non-cash consideration. Ordinarily, it is required that the fair value of the skim oil is to be estimated at contract inception; however, due to variability of the form of the non-cash consideration, the amount and dollar value is unknown at the contract inception date. Accordingly, ASC 606-10-32-11 allows us to value the skim oil on the date in which the value becomes known.

The Water Solutions segment has certain disposal contracts that contain the following types of terms or pricing structures that involve significant judge that impacts the determination and timing of revenue.

• Minimum volume commitments. We receive a shortfall fee if the customer does not deliver a certain amount of volume of wastewater over a specified period of time. At each reporting period, we make a determination as to the likelihood of us earning this fee. We recognize revenue from these contracts when (i) actual volumes are received; and (ii) when the likelihood of a customer exercising its remaining rights to make up the deficient volumes under minimum volume commitments becomes remote (also known as the breakage model).

• Tiered pricing. For contracts with tiered pricing provisions, the period in which the tiers are earned and settled (i.e. the “reset period”) may vary from monthly to over a period of multiple months. If the tiered pricing is based on a month, we allocate the fee to the distinct daily service to which it relates. If the tiered pricing spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise our estimates of variable consideration at each reporting date throughout each reset period.

• Volume discount pricing. Volume discount pricing is a form of variable consideration whereby the customer pays for the volumes delivered on a cumulative basis. Similar to tiered pricing, the period in which the cumulative volumes are earned and settled (i.e. the “reset period”) may vary from daily to over a period of multiple months. If the volume discount is based on a month, we allocate the fee to the distinct daily service to which it relates. If the volume discount period spans across multiple reporting periods, we estimate the total transaction price at the beginning of each reset period, based on the expected volumes. We revise the estimate of variable consideration at each reporting date.

For all of our disposal contracts within the Water Solutions segment, revenue will be recognized over time utilizing the output method based on the volume of wastewater or solids we accept from the customer. For contracts that involve the sale of recovered hydrocarbons and freshwater, we will recognize revenue at a point in time, based on when control of the product is transferred to the customer.

Liquids Performance Obligations

Within the Liquids segment, revenue is disaggregated into two primary revenue streams that include revenue from the sale of commodities and service revenue. For commodity sales, we are obligated to deliver a specified amount of product over a specified period of time. For these types of agreements, revenue is recognized at a point in time based on when the product is delivered and control is transferred to the customer. For revenue received from services rendered, we offer a variety of services which include: (i) storage services where product is commingled; (ii) railcar transportation services; (iii) transloading services; and (iv) logistics services. We are obligated to provide these services over a predetermined period of time. Revenue from service contracts is recognized at a point in time upon the transfer of control each month. All revenue from services is recognized over time utilizing the output method based on volumes stored or moved.

Refined Products and Renewables Performance Obligations

The Refined Products and Renewables segment has one distinct revenue stream, which is revenue from commodity sales. In these agreements, we are obligated to sell a predetermined amount of product over a specified period of time. Revenue for all commodity sales is recognized at a point in time once the customer has lifted the agreed-upon volumes.

Remaining Performance Obligations

Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements.

During the three months ended June 30, 2018, we entered into a definitive agreement, as described further in Note 13, in which we agreed to provide the benefit of our deficiency credit under one of these contracts. As a result of providing this benefit to the third party, we wrote off $67.7 million of these deficiency credits to loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statements of operation during the three months ended June 30, 2018. Under the remaining other contract for which we have the future benefit, we currently have 22 months in which to ship the excess volumes.

Amounts in the table above do not include other noncurrent assets related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).

(1) We may purchase or sell a physical commodity where the underlying contract pricing mechanisms are tied to different commodity price indices. These contracts are derivatives we have entered into as an economic hedge against the risk of one commodity price moving relative to another commodity price.

These contracts are derivatives we have entered into as an economic hedge against the risk of mismatches between fixed and floating price physical obligations.

Amounts in the table above do not include commodity derivative contract positions related to the Retail Propane segment, as these amounts have been classified as assets held for sale within our unaudited condensed consolidated balance sheets (see Note 14).
